Manual U This manual contains information for installation, operation, maintenance and repair. It should be read by installers, operators, maintenance personnel, and other personnel who may come in contact with this equipment. This manual covers the Unifoiler series of cap sealing systems. All of these systems incorporate an inverter, and a sealing coil as standard equipment. Other options are available, such as a unitized stand on wheels, or a missing foil / stalled bottle detection system. Some references in the manual may not reflect your particular equipment configuration but each component of your system will be explained individually. If you have any questions regarding the installation or use of the product, you may contact a Pillar Technologies representative for advice. You may also contact the Service Department directly during normal working hours between 8:00 a.m. and 5:00 p.m. CDT. In case of an emergency, a 24-hour a day, seven-day a week service hotline is available. Your message will be forwarded to a service representative who will then return your call. Some Terms U Some terms used throughout this manual: Optical sensor - This refers to the type of device that is used to detect the presence of an object within the beam of light. The sensors used in your system are through-beam. It consists of two sensors in alignment with one another across the conveyor that the containers pass between. Capacitor bank - The capacitors are located within the enclosure on the top of the sealing coil. These work together with the sealing coil to generate the high-energy electromagnetic field. Locating the capacitors at the coil eliminates the need for heavy, water-cooled leads to the coil. IGBT - Insulated Gate Bipolar Transistor. A very rugged type of transistor that can accommodate high power. Impedance - An electrical value associated with ability of the inverter to match the sealing coil's electrical characteristics and power requirements. This value changes in response to the amount of 1 INTRODUCTION metal passing through the sealing coil's electromagnetic field. Inductive sensor - This is a type of electronic sensor that detects the presence of metallic objects when passed near it, such as a foil liner. Induction - The phenomenon where electrical energy is transferred from one device to another through the air by an electromagnetic field. Inverter - This is the electrical unit that supplies high voltage, high frequency energy to the sealing coil. Transformer tap - The inverter contains a transformer that couples it with the sealing coil. Different size bottle caps will load the sealing coil differently. A voltage tap connection on the transformer is changed to permit the proper coupling of energy between the inverter and the foil liner. Universal coil - A special sealing coil available exclusively from Pillar that permits sealing of a wide range of cap sizes without changing coil sizes. It works by angling the coil with respect to the conveyor path. Whatever the cap size, the entire cap will pass through the electromagnetic field. Channel coil - A coil design which is directed toward the various child resistant and dispenser type caps which would be very difficult to seal using a convention flat coil system. The sealing coil allows for the container neck and cap to pass through the electromagnetic field inside the tunnel, providing uniform heating and sealing to the container. Product Description U An induction cap sealing system is used to apply a hermetic seal over the mouth of a jar or bottle. These seals can provide evidence of tampering, preserve freshness, prevent pilferage, and provide leakage protection during handling or shipping. A special plastic cap containing an aluminum foil disk is used. After the cap is screwed onto the bottle, it is passed beneath an induction sealing coil. This coil radiates an electromagnetic field, which causes the aluminum disk to heat up. A coating laminated to this disk softens and is fused to the mouth of the bottle. Features: The inverter circuitry employs IGBT technology. The IGBT is a rugged, state-of-the-art transistor device now being used in critical, high power circuitry for military and commercial aircraft. The inverter is forced-air cooled and operates quietly and reliably without the need for expensive and high maintenance water cooling systems. 2 INTRODUCTION The cap sealer utilizes a stainless steel enclosure with corrosion resistant components and hardware. The inverter cabinet is designed for ease of installation on most conveyor styles. With the unitized system, the entire system is located at the conveyor where the operator can easily view the controls and make necessary adjustments. The locally mounted operator panel puts all the operator functions right at the point of operation. A standardized coil mounting system accepts any Pillar sealing coil. Several styles of sealing coils are available to adapt to a variety of sealing needs. The coils are easy to mount, simple to adjust, and can be quickly removed for fast and efficient coil exchange. Safety U Equipment Safety Features U Any moving parts could cause injury if a person comes in contact with them. The containers moving through the equipment are no exception and caution should be used when working around the equipment during operation. For your safety, you should never bypass the interlocks or guarding system while the equipment is operating. Precautions U Pillar Technologies makes every effort to build equipment that is safe and as free of hazards as technically possible. However, not all hazards can be totally eliminated by design. It is therefore imperative that all personnel who will use or service the equipment become familiar with this manual. Areas in this manual concerning safe operation are identified with the following symbols. CAUTION The cap sealing system creates an electromagnetic field that will cause heating in metal objects brought into proximity of the sealing coil. It is recommended that rings, watches, bracelets, or other jewelry not be worn when working near the coil. Serious injury could result if these items are worn near the coil. 3 INTRODUCTION The cap sealing system is not designed to be located in a wash down, wet, or hazardous environment. The customer must ensure that all applicable safety code requirements are complied with when installing this equipment. Input power must always be disconnected and locked out at the source before service or setup of the equipment. All guards, shields, and barriers must be in place before starting the equipment. Do not operate, troubleshoot, or maintain the cap sealing equipment while under the influence of any type of drug or alcohol. Proper maintenance of the equipment, including periodic inspection , is necessary to maintain the highest degree of safety. U U Always observe all safety warnings and notices on the equipment and in this manual. 4 INSTALLATION Installation U Unpacking U Your Pillar cap sealer has been completely tested, inspected, and carefully packaged prior to shipment. Please remove the packing materials carefully and watch for any visual signs that the equipment may be damaged. Also ensure that all packing material is carefully inspected for components which may be hidden within them. If upon arrival you find that the equipment has been damaged in route, please do the following: Retain all packing materials in which the equipment was originally shipped for possible inspection by the carrier. Notify the carrier immediately upon confirmation of the damage and file the appropriate claim. Notify Pillar Technologies as soon as possible for instructions regarding the damaged equipment. NOTE: Failure to contact the carrier prior to installation of the equipment or disposal of the packing materials may result in loss of claim from the carrier. Stationary Coil Support U The coil support is to be mounted at the spot on the conveyor system where the sealing is to take place. Normally, this is directly after the capper, where the bottles will still be spaced apart. Figure 1 shows the components of the coil support assembly. Generally, the support's mounting plate can be attached directly to the side of the conveyor. However, it may be necessary to fabricate a plate or bracket to adapt to a particular conveyor. A bracket could be made to mount from the floor, if desired. In any case, the installation must be rigid. If the coil support is mounted directly to the conveyor, bracing of the conveyor may be necessary to provide sufficient rigidity. When planning the location of the mounting plate, note that the range dimensions in Figure 1 are given from the bottom of the attachment plate, not the bottom of the coil. The thickness of the coil depends on the particular style used. Consider also the range of bottle sizes that are intended to run under the coil. 5 INSTALLATION 3.12" [79.38] MIN 7.62" [193.55] MAX Figure 1 6 Stationary Conveyor Mounted Coil Support INSTALLATION Unitized Stand U To minimize the installation and setup time required, an optional unitized system is available which combines the inverter cabinet, coil support, and sealing coil onto a common frame with casters for easy movement from location to location. A typical unitized system is shown in Figure 2. The basic components include the inverter cabinet and the adjustable coil support stand. The leveling feet should be lowered to the floor, preventing tipping, and stabilizing the installation. CAUTION POWER SUPPLY STAND MUS T BE LOWERED BEFORE MOVING MACHINE Figure 2 Typical Unitized System Components 7 INSTALLATION POWER SUPPLY STAND MUST BE LOWERED BEFORE MOVING MACHINE Regardless of the type of coil support provided, the system must be mounted level so that the coil will lie parallel to the conveyor's surface. It is important that the gap between the top of the bottle cap and the bottom of the coil remain constant as the bottle passes underneath. Verify this by mounting a coil and measuring the distance from each end down to the conveyor track or belt as shown in Figure 3. On narrow conveyors, it may be necessary to space the coil support mounting plate further away from the rear side of the conveyor. Figure 3 - Checking that the coil is level 8 INSTALLATION Inverter U The inverter enclosure is not designed to be located in a wash-down, wet, or hazardous environment! The inverter is air-cooled and contains a fan to force air through the enclosure. A minimum of six inches of clearance should be provided on both the sides and rear of the enclosure to ensure adequate airflow. The 208 or 240 VAC (single phase) input power enters at the rear of the cabinet and a safety disconnect is provided with lockout capability. A cord grip has been provided to accommodate a power cable. If another type of fitting is needed, some modifications to the cabinet may be necessary. The customer must provide the necessary circuit protection (fusing or circuit breakers) in accordance with applicable codes and practices. The systems are wired for 240 VAC power when they leave the factory. Full specifications are listed on page 43. Refer to the wiring diagram BE3453-33 on page 11 for power input terminals connections. Never connect input power to disconnect terminals (1) and (3) simultaneously. Damage will occur to the inverter. Also see the wiring diagrams at the end of this manual for control transformer tap changes for your supply voltage. The sealing coil connection is provided at the rear of the cabinet and can be easily removed for fast coil change over or maintenance. Figure 4 shows a typical inverter arrangement. It is the customer s responsibility to ensure that all applicable safety code requirements are complied with when installing this equipment. Cables to the coil should be routed back to the inverter along the coil support to prevent cables from obstructing container flow. 9 INSTALLATION Provisions have been made to allow customer alarm or interlock circuitry to be wired into the inverter. Details on using these interlocks may be found on page 14. If optional equipment has been provided, or if special features have been incorporated into your equipment, please refer to the specific wiring diagram for that option or feature. A unitized adjustable stand is also available to reduce installation time and is described in more detail on page 7. If the system was shipped as a stand-alone cabinet, it can be located in any convenient location that provides adequate ventilation for cooling. Figure 4 - Typical Inverter Cabinet 10 INSTALLATION 11 INSTALLATION Sealing Coil U Coil failures due to overheating can result in personal injury. Please ensure that all safety interlocks and protection devices are connected and functioning properly. There may be several different styles of sealing coils available that can adapt to various applications. The method of mounting is the same for all styles of conveyor coils. All coils styles consist of an inductive winding, a load capacitor, and a housing to hold these components. Always disconnect the supply power from the cap sealer before mounting or removing sealing coils To mount the conveyor coil, rotate the clamp lever counterclockwise until it is loose enough to slide onto the support. A spring will force the flanges apart to provide clearance for mounting. The screw mechanism has a stop that prevents the handle from coming off. Note: Do not rotate the clamp lever past the stop position. Lift the coil up to the attachment plate and slide it into the slot. Rotate the lever clockwise and tighten until the coil is secure. Final alignment of the coil is discussed in the Setup section, starting on page 15. Connect the power cable from the coil to the back of the inverter cabinet. It is important that this connector be properly positioned and securely fastened. 12 INSTALLATION Due to the sealing coil weight, it is recommended that the installation be performed by two people, or with the assistance of a mechanical aid. Optional Equipment U U Optional equipment may have been purchased at the time of original purchase. If this is the case, the optional equipment will be installed on the Unifoiler system as much as possible. For more information on specific options, please see the Optional Equipment section of this manual. Wiring Besides power input and interlocking, there are several other terminals available for optional equipment and special features when provided. The system schematic diagrams appear on pages 5057. Please refer to these documents when installing your cap sealing system, and if you have any questions regarding your installation, contact the Pillar Service department. AC input - The supply voltage is connected to the disconnect switch provided at the rear of the inverter cabinet. Line fuses are provided at the main terminals to protect the inverter components. The system can be connected for 208 or 240 VAC +/- 10%, single phase. Refer to drawing BE3453-33 on page 11 for the connection diagram. Also see the system schematic diagram at the end of this manual for further information. Auto-start - A contact closure across terminals [77] and [93] will enable the auto-start feature. This feature could be used to put the cap sealing system into a standby mode when the conveyor system stops. When the conveyor starts again, the cap sealing system will resume operation automatically. When the contacts are closed, the cap sealing system will be in a ready condition. Initially, the START button is pressed and the unit runs. If the contacts are opened, the cap sealing system will stop delivering power to the sealing coil, but will remain in a ready state. When the contacts are closed again, operation will resume, if no fault condition exists. If the safety interlocks or external customer interlocks are opened, the cap sealing system will shut down completely. To resume operation, the interlocks must be satisfied, the auto-start contacts closed and the START button pressed. If this feature is not used, a jumper must be installed across these terminals. 13 INSTALLATION Note: Jumper J3 on the main control circuit board will inhibit this feature. If the auto-start function is to be used, this jumper must be removed. Note: When the stalled bottle feature is enabled, the operator needs to restart the inverter at the main operator panel prior to resuming operation. Customer interlock - Terminals [89] and [90] are provided for the customer interlock, and can be used to stop the cap sealing system. For the unit to run, a maintained contact closure is required across these terminals. When the contacts open, the unit will stop. Once the contacts are closed again, the START button must be pressed to resume operation. If this functionality is not required, a jumper must be placed between these terminals. Low output alarm (LSI) - This alarm activates the user alarm indicator and alarm relay, which changes state, to signal a loss of seal condition. Both normally open and normally closed contacts are available at terminals [94], [95], and [96]. (See pages 50-57) Use these terminals to activate an alarm or to shut down the conveyor system when the cap sealing system is not delivering sufficient output compared to the alarm set point. When the set point for this alarm is adjusted to zero, the relay contacts will not change state, even if the output of the power supply is zero. Run mode monitor - Whenever the cap sealing system is running, the run relay will be energized. Both normally open and normally closed contacts are available at terminals [97], [98], and [99]. (See pages 50-57) Use these terminals to monitor the operational mode of the cap sealing system. Temperature switch interlock - This interlock is used to monitor the operation of the coil cooling system (fan), and is internally connected to the inverter whenever the coil cable is connected. 14 SETUP Setup There are different procedures for setting up coils, depending on the style, but for all types of coils it is important that the conveyor guide rails are adjusted properly to allow bottles to pass without restriction. Containers must pass under the sealing coil unimpeded and with adequate speed to prevent overheating. Containers that pass to slow or stall may overheat and possibly catch fire. Depending on the size of bottle cap, a limit may occur in the inverter, preventing full output power from being obtained. This condition occurs when the load on the inverter is higher than it can deliver. If the power meter reading on the front panel of the power supply decreases when there are bottles under the coil, change the output transformer tap. Please see the discussion on changing transformer taps at the end of this section. Universal Coil The universal coil can adapt to a very wide range of cap sizes and shapes which allows the same coil to be used for a number of different applications. This is accomplished with a special coil design that allows you to angle the coil along the path of the conveyor. To achieve the best performance from this coil, follow the setup instructions below. Due to the sealing coil weight, it is recommended that the installation be performed by two people, or with the assistance of a mechanical aid. 1. Place a bottle with a cap under the coil. Adjust the vertical crank until there is about 1/8" (3 15 SETUP mm) clearance between the bottom of the coil and the top of the cap. Slide the bottle from one end of the coil to the other to check the clearance. It is important that the same spacing be achieved from one end of the coil to the other. This clearance must be enough to ensure that a bottle with a loose or crooked cap will not jam under the coil. 2. Loosen the coil mounting clamp lever. 3. Note the centerline marks on each end of the coil. Slide and swivel the coil so that the mark on the entrance end of the coil is positioned ¼ outside of one edge of the bottle cap. The mark on the exit end of the coil is to be positioned ¼ outside of the opposite edge of the bottle cap. In other words, the centerline of the coil is to sweep across the full width of the bottle cap. See Figure 6 below for additional adjustment instructions. It is best to angle the capacitor bank side of the coil over the conveyor. 4. Firmly tighten the coil mounting clamp lever. Make sure that the coil does not swivel during tightening. Figure 6 - Adjusting the Universal Coil 16 SETUP Channel Coil The channel coil is intended for specialty caps such as those with spouts. Channel coils are designed to fit a specific cap diameter and height. Verify that the coil to be mounted is appropriate for the type of cap to be sealed. Figure 7 Channel Coil 1. Note the horizontal scribe marks on each end of the coil. These show the location of the sealing field. Adjust the vertical crank until these markings are even with the lip of the bottle where the foil seals. 2. Loosen the coil mounting clamp lever. 3. Slide and swivel the coil so that the bottle can pass underneath from one end to the other without 17 SETUP the cap rubbing the sides of the channel. 4. Firmly tighten the coil-mounting clamp. Make sure that the coil does not swivel during tightening. Transformer Tap Changes Always disconnect the supply power from the cap sealer before removing the enclosure cover. Never attempt to change transformer taps with power applied. If the bottling line is capable of a variety of bottles and caps, it may be necessary to change the output transformer tap to achieve maximum sealing performance. Different size bottle caps will load the inverter differently and may cause a mismatch between the inverter and the sealing coil. The output transformer taps are provided to compensate for this condition. The power output terminal strip located on top of the output transformer contains several terminals corresponding to different taps of the transformer. Refer to the wiring diagram on pages 50-57 when changing transformer taps. One output wire from the sealing coil must be connected to the H1 terminal. The other wire can be attached to terminal H2, H3 or H4. Tap 1 (H2) is the lowest voltage; tap 3 (H4) is the highest voltage. If the impedance low indicator lights, try changing to a lower voltage tap. If small caps do not seal well, try changing to a higher voltage tap. For best results, use the highest voltage tap that does not cause the impedance low indicator to light. If the highest voltage tap does not produce adequate sealing, the conveyor speed must be reduced to allow the cap to remain under the coil for a longer time. 18 SETUP Before Starting Do not wear jewelry such as watches, rings, or bracelets while working near the sealing coil. Metal objects can become extremely hot if brought into close proximity of the sealing coil when power is applied. Always keep hands clear from under the coil unless you are certain that the inverter is shut off. 1. Check to be sure that the coil has been mounted and aligned as described above. 2. Check to see that the power cable connected between the coil and the inverter is properly seated and securely tightened. 3. Make certain that all enclosure doors are properly closed and that all internal and external interlocks are closed. 19 OPERATION Operation Inverter A disconnect switch is located on the rear of the cabinet. This switch removes all power from the inverter cabinet. A circuit breaker, which is also located on the rear of the cabinet, protects the internal circuitry from damage. The circuit breaker also supplies power to inverter components and options. READOUT SELECTION POWER SET POINT ALARM/TIMER SET POINT RUN SETUP DURATION RESET START STOP DELAY Figure 8 - Operator Panel The operator panel shown in Figure 8 above contains the diagnostic indicators, status indicators, operating set points, and a digital meter, which indicates output power. Refer to the troubleshooting section starting on page 41 for advice on how to interpret the different lights. A brief description of their function will be given here. Diagnostic Lights Setup - Indicates that the system is in the set up mode for the bottle and cap detection option. Refer to the section on detection systems for further details. Inverter On - Indicates that power is being supplied to the sealing coil. When indicator is flashing, this means that the auto start contact is open and that the inverter is in standby mode and ready to turn on when the auto start contact closes. Alarm Fault - Lights when the coil output has dropped below the threshold set by the alarm set point on the panel. This is used to indicate that the inverter is not supplying the desired power to the coil. In such a case, proper sealing may not be accomplished. This light shows that the alarm circuitry is active. 20 OPERATION Impedance High - If this light should illuminate when the inverter is in Stop mode, it does not indicate a problem. If it illuminates while the inverter is running, there may be a problem inside the inverter or coil. Typically this indicates that a capacitor within the coil assembly has opened up. In this event, please contact Pillar Service. Impedance Low - Indicates that an impedance mismatch has occurred. This condition occurs when the load on the inverter is higher than it can deliver. When this occurs, the output transformer tap may need to be changed to deliver a lower voltage to the sealing coil. Refer to page 18 (transformer tap changes) for more information. Note: If this light illuminates when the inverter is in Stop mode, it does not indicate a problem. High Temp - Indicates that the power transistors inside the inverter are not receiving sufficient cooling. The inverter will shut down to prevent the unit from overheating. If this light illuminates, you should call Pillar Service. Reject Fault Indicates that the reject verification sensor did not sense a bottle moving into the reject tray. Also illuminates during SETUP when the reject verification sensor is blocked. Current Trip - Indicates that a short circuit has occurred between the inverter and the coil. The inverter will shut down to protect the output circuits. If this light illuminates, you should call Pillar Service. Under Voltage Trip - Indicates that the supply voltage to the inverter has dropped (as in a brownout). The inverter will shut down to prevent the inverter from drawing excessive current. Check the supply voltage. Over Voltage Trip - Indicates that a voltage surge or other situation has caused an over-voltage condition within the inverter. The inverter will shut down to protect itself. Stalled Bottle Fault - When this light is illuminated it is a warning that a Stalled Bottle condition was detected at the sealing coil. Also lights when rejected bottle button is pressed. Refer to the Stalled Bottle section in this manual for further information on this system. Note: Only applies to systems that include this option. Loose Cap Fault - When this light is illuminated, it indicates that a cap was detected which is not fully seated on the container or is not threaded evenly causing a fault condition. Also lights when rejected bottle button is pressed. Refer to the Loose Cap Detector section in this manual for further information. Note: Only applies to systems that include this option. Missing Foil Fault - When this light is illuminated, it indicates that a container passed under the sealing coil that did not have a liner installed, and was not properly sealed. Also lights when rejected bottle button is pressed. Refer to the Missing Foil Detector section in this manual for further information. Note: Only applies to systems that include this option. Zero Speed Fault - When this light is illuminated it is a warning that a Zero Speed Condition 21 OPERATION was detected at the conveyor. If enabled, the Zero Speed Fault LED will illuminate when there is a zero speed fault instead of the STALLED BOTTLE FAULT. Note: Only applies to systems that include this option. Operator Controls LED Display - Shows the power level in percent being delivered by the inverter to the sealing coil. Power - When pressed the display will read the requested power set point and if the inverter is running it will return back to actual power when released. Active when green indicator is lit on button. Alarm Set - Pressing this button allows the operator to view the Alarm Set Point on the display and change as required. Active when green indicator is lit on button. Total Bottle - Indicates the total number of containers that have passed through the sealing coil. Not available without the optional detection system. Reset by holding the button for 5 seconds. Rejected Bottle - Indicates the total number of rejects due to a stalled bottle, loose cap, or missing foil fault. Not available without the optional detection system. Reset by holding button for 5 seconds. Total Run Time - Indicates the total number of operating hours on the system. Reset by holding the button for 5 seconds. Power Set Point - Digital entry of the percentage of output power. This setting will control the amount of heating induced in the bottle caps. To change the setting, press the up or down button next and set for the appropriate level on the display. Alarm / Time Set Point - Digital entry of the alarm threshold. If the actual power output to the coil falls below this setting, the alarm circuitry will be activated. This is sometimes called the loss of seal condition. Note: Set the alarm to "0" if the alarm function in not needed. Digital entry of the hand held coil on time. The on time (duration) is adjustable anywhere from 0-10 seconds. NOTE Always set the alarm set point below that of the power setting. If the alarm setting is the same or higher than the power setting, the alarm circuitry will activate. Start - Energizes the inverter causing selected power to be delivered to the sealing coil. 22 OPERATION Stop - De-energizes the inverter to cease delivering power to the sealing coil. This does not shut off the internal circuitry of the inverter. Also is used as a reset for the under voltage trip, over voltage trip, and current trip. Reset - Pressing this button after a stalled bottle, loose cap, or missing foil condition has occurred will enable the inverter as long as the fault no longer exists. Note: Only applies to systems that include these options. The reset button also serves as an alarm silence. If the loss of seal alarm is used, pressing this button will silence the loss of seal alarm. Note that the alarm can only be silenced if the capsealer is stopped. The first push of the reset button will silence the alarm. The second push of the reset button will clear any fault that is present. Run/Setup - Pressing this button will toggle between the run and setup mode for the stalled bottle detector. The setup LED will also light when in the setup mode. Power Setting It may be known from previous experience what power setting should be used for a particular cap and conveyor speed. It is always a good idea to test the setting once a setup has been changed, to assure that good seals are achieved before running production. Do not wear jewelry such as watches, rings, or bracelets while working near the sealing coil. Metal objects can become extremely hot if brought into close proximity of the sealing coil when power is applied. Always keep hands clear from under the coil unless you are certain that the inverter is shut off. 1. Determine the necessary speed of the conveyor. An increase in conveyor speed will reduce the amount of heat developed in each seal. A proportional increase in inverter output will be required to maintain seal quality. Once the proper speed has been determined it should remain constant. 23 OPERATION 2. Insure that the coil is properly mounted and positioned. 3. Set the Alarm setting to "0" or some low setting. Set the power level at some arbitrary value (such as 50%). Press the start button. Place a bottle onto the conveyor and let it run under the coil. 4. Retrieve the bottle and allow a few seconds for it to cool. Remove the cap and inspect the seal. The foil must be completely sealed around the lip of the bottle, without melting into the lip. Also, the wax must release from the foil. 5. Adjust the power level up or down as needed and test a new bottle. Repeat with a new bottle each time until a satisfactory seal is obtained. 6. Note the power setting, coil gap, and conveyor speed for future reference. 7. If the alarm will be used set the value to a few percent lower than the power setting. If the alarm function is not needed, set the control to "0", or at least a value significantly lower than the power setting. If it is not possible to get good sealing when the inverter is set at maximum power, either the output transformer tap needs to be changed or the conveyor speed must be reduced. Refer to page 18 (transformer tap changes) for more information. 24 OPTIONAL EQUIPMENT Optional Equipment Stack Light A three level, high visibility, stacked light assembly mounted to the rear of the inverter to indicate a Run (green), Stop (red), or Loss of seal (amber) condition. The lights easily mount to the inverter cabinet and a connector is provided to simplify the installation. This option can also be quickly added to existing equipment provided that it supports this option. Figure 9 below shows a typical location for a system with an optional stack light. (Note that this option utilizes the power supply loss of seal contact and run contact. These contacts will not be available for customer use.) Figure 9 Optional Stack Light 25 OPTIONAL EQUIPMENT Bottle and Cap Detection System The Bottle and Cap Detection System utilizes the latest sensor technology to detect one of three fault conditions, stalled bottle, missing foil, or loose cap. Each one of these faults is discussed in detail below. Please see the drawing of a typical detection system at the end of this section. Stalled Bottle Detector The purpose of the stalled bottle sensor assembly is to detect bottle movement on the conveyor line and activate an alarm if a bottle becomes stalled under the induction sealing coil. The stalled bottle option will also shut down the power supply when the fault occurs. If a container should stall beneath the coil, the foil liner may overheat, resulting in burning of the liner and the container, resulting in a potential safety hazard. The system senses containers entering the seal zone and also senses the containers leaving the seal zone. At the same time a third sensor monitors the conveyor speed and is used to record the proper amount of time for a container to pass between sensors. Even a slight delay from entrance to exit will cause an alarm to activate. If it is desirable to disable this option, locate the dip switches on the display circuit board and turn off switch #1. The stalled bottle detector requires two sets of photoelectric sensors located at each end of the sealing coil. Brackets are provided for mounting these sensors to the conveyor system. The outputs from these sensors are connected to the display circuit board located in the inverter enclosure. In addition, an optical encoder is also provided, which requires mounting onto the conveyor shaft at a convenient location. The output of this encoder is also connected to the display circuit board. Please see the encoder mounting instruction drawing located after this section. Specifications Minimum Conveyor Speed: 7 ft/min (2.13 M/M) Maximum Conveyor Speed: 250 ft/min (76.2 M/M) Minimum Cap Diameter: 28 mm Minimum Distance Between Caps: 1/4 inch (6.4 mm) Maximum Distance Between Sensors: 48 inches (1219.2 mm) 1 1 TP PT Smaller size bottles can be used with this system but the maximum conveyor speed of the system may change. TP PT 26 OPTIONAL EQUIPMENT Note: A minimum opening is required between caps so that the sensors can detect when a bottle is present and when it isn't. Container shape and neck configurations are also a factor in achieving reliable operation. Features Indicator Lamp - Light located on display panel lights when a stalled bottle fault occurs. Reset Button - Allows the operator to silence the alarm during a stalled bottle fault. Fail Safe Operation The system will also monitor the conveyor speed, and will give a stalled bottle fault if the conveyor speed drops below 7 ft/min (2.13 M/M). Reject Counter - A display that shows the number of rejects caused by stalled bottle faults. Function During normal operation, the stalled bottle system will monitor bottles passing under the sealing coil and indicate a fault condition should a container stall or jam. When a stalled bottle fault occurs, the system will stop the inverter output to the sealing coil and open an external contact at terminals [111] and [112] which is provided for customer use. (Note: this contact is closed during a normal run condition.) The interlock contact will turn off the power supply preventing damage to the product and the sealing coil. Once a stalled bottle fault occurs, the operator must remove all containers between the sensors before trying to reset the fault. If the operator does not clear all containers between the sensors, a false indicating fault will occur. This stalled bottle system will also monitor the entrance sensor. Should the entrance sensor not sense a passing bottle and the exit sensor does, a fault condition will occur. This allows for fail safe operation and eliminates the possibility of a stall condition not being detected. If any of the sensors are miss-aligned or damaged in any way, the system will detect a problem and a fault condition will occur preventing the system from operating. The stalled bottle faults are stored in memory and the total number of faults that occurred can be seen by pressing the rejected bottle count button. Each time the rejected bottle count button is pressed it will sequence through all the available options, like stalled bottle, missing foil, loose cap, etc. You can determine which faults have occurred by the LED indicators. Holding the rejected bottle count button in for a period greater than 5 seconds will reset all the fault counters. Missing Foil Detector The purpose of the missing foil detection system is to provide a warning to the operator in the event that a container passes under the sealing coil that did not have a liner installed. If a 27 OPTIONAL EQUIPMENT container passes under the inductive sensor that does not have a foil present, the inductive sensor will send a signal to the microprocessor, the processor will then provide a signal to alert the operator. This option does not shut down the inverter, but can be used with a reject mechanism to remove defective containers from the conveyor line. If it is desirable to disable this option, locate the dip switches on the display circuit board and turn off switch #2. The missing foil system consists of a photoelectric sensor that detects the presence of a container at the same time that the inductive sensor is looking for a foil under it. (The photoelectric sensor is the same one used for the stalled bottle function.) The outputs from both of these sensors are connected to the display circuit board the inverter enclosure. In addition, the optical encoder mentioned in the stalled bottle section is also required. Features Indicator Light - Light that is located on the display panel, which indicates when a missing foil fault has occurred. Adjustable Fault Contact A timed contact used to activate a bottle reject. Dependable Operation - The sensing of the container and the foil at the same time allow for failsafe operation and dependable detection of foils. Reject Counter - A display that shows the number of rejects caused by missing foil faults. Function During normal operation, the bottles pass under the foil sensor and past the bottle sensor at the same time. As long as the foil sensor detects a foil while the bottle sensor is activated the system will continue to operate normally. If a cap without a foil should pass under the foil sensor, a signal will not be received by the microprocessor and this will cause a foil detection fault to occur. When this happens, the fault light on the display panel will light and the reject contact on terminals [83] and [84] will close, indicating a missing foil was detected. This contact can be used to activate an alarm or to activate a reject mechanism to remove the container from the conveyor. Please see the Setup and Operation section below for reject setup. The missing foil faults are stored in memory and the total number of faults that occurred can be seen by pressing the rejected bottle count button. Each time the rejected bottle count button is pressed it will sequence through all the available options, like stalled bottle, missing foil, loose cap, etc. You can determine which faults have occurred by the LED indicators. Holding the rejected bottle count button in for a period greater than 5 seconds will reset the all the fault counters. Loose Cap Detector The loose cap detection system is used to detect the presence of a cap that is not fully seated, or a 28 OPTIONAL EQUIPMENT crooked cap, or even a container which is not setting flat on the conveyor. The result of any of these conditions will cause an output signal to an external relay which can be used to activate an alarm device, or provide the signal to a reject mechanism on the conveyor. If it is desirable to disable this option, locate the dip switches on the display circuit board and turn off switch #3. The loose cap system consists of a photoelectric sensor and a retro-reflective laser sensor that are mounted at the exit of the sealing coil. The photoelectric sensor senses the presence of a container exiting the sealing coil area. (The photoelectric sensor is the same one used for the stalled bottle function.) The retro-reflective laser sensor is looking for a cap that is not at the correct height on the conveyor. The outputs from both of these sensors are connected to the display circuit board the inverter enclosure. In addition, the optical encoder mentioned in the stalled bottle section is also required. Features Indicator Light - Light that is located on the display panel indicates when a loose cap fault has occurred. Adjustable Fault Contact A timed contact used to activate a bottle reject. Dependable Operation - The sensing of the container and the cap at the same time allow for failsafe operation and dependable detection of loose or crooked caps. Reject Counter - A display that shows the number of rejects caused by loose cap faults. Function During normal operation the loose cap sensors will detect a container passing through the sealing coil with the bottom sensor and also look for no obstruction of the beam with the upper sensor at the same time. If the upper sensor beam is broken while the lower sensor detects a container, a fault will occur and a signal is fed back to the microprocessor. The microprocessor will activate the reject contact on terminals [83] and [84] indicating a loose cap was detected. This contact can be used to activate an external alarm or to activate a reject mechanism on the conveyor. When a cone or dispenser style cap is being used, dip switch #6 needs to be in the on position. Dip switch #6 is located on the display circuit board. During normal operation, the upper sensor will detect the raised portion of the cap while the bottom sensor detects the base of the cap. When the upper sensor beam is broken for a period greater than the width of the raised portion recorded during setup, the reject contact will be activated. The loose cap faults are stored in memory and the total number of faults that occurred can be seen by pressing the rejected bottle count button. Each time the rejected bottle count button is pressed it will sequence through all the available options, like stalled bottle, missing foil, loose cap, etc. You can determine which faults have occurred by the LED indicators. Holding the rejected bottle count button in for a period greater than 5 seconds will reset all the counters. 29 OPTIONAL EQUIPMENT Setup and Operation 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 30 Attach the encoder to the conveyor per drawing AI529-39 (Figure 10). Use the supplied shoulder bolt to attach the encoder to a conveyor shaft. The conveyor shaft will need to be tapped for a 5/16 18 thread. Route the encoder cable from the sealer power supply to the encoder. Ensure that the cable will not get entangled in the conveyor or any other moving part. Turn on the power to the sealer power supply. Adjust the coil height to container being sealed. See instructions on adjusting the coil elsewhere in this manual. At the entrance to the sealing area there are two photoelectric sensors. These are designated as sensor #1. One sensor emits a red beam of light, where as the other receives the beam of light. On the receiver there is a green light (power on) and a yellow light (light beam received). Place a container with a cap at the entrance sensor pair. Loosen the four bolts on the sensor bracket and gently lower the entrance sensors until the yellow light (light beam received) on the receiver goes out. Preferably adjust the sensors to just below the bottom of the cap. Tighten the four bolts on the sensor bracket. At the exit to the sealing area there are two photoelectric sensors. These are designated as sensor #2. One sensor emits a red beam of light, where as the other receives the beam of light. On the receiver there is a green light (power on) and a yellow light (light beam received). Place a container with a cap at the exit sensor pair. Loosen the four bolts on the sensor bracket and gently lower the exit sensors until the yellow light (light beam received) on the receiver goes out. Preferably adjust the sensors to just below the bottom of the cap. Tighten the four bolts on the sensor bracket. Place a container with cap and foil under the inductive foil sensor (designated as sensor #4). Lower the inductive foil sensor by loosening the lock nuts on the sensor barrel. Lower until the indicator light on the foil sensor is illuminated. Make sure that the foil sensor will not obstruct the light beam of the loose cap sensor. The loose cap sensor is a retro-reflective laser sensor. This sensor is designated as sensor #3. The loose cap sensor is located on the same bracket as the foil sensor. This laser sensor utilizes a reflector mounted on a bracket across the conveyor from the laser. If the beam is broken, a loose cap fault has occurred. Adjust the sensitivity of the loose cap sensor by turning the potentiometer on the back of the sensor until the yellow LED goes out. Turn the potentiometer back until the yellow LED just comes on. The yellow LED must be on solid (not flashing) with out a container present. Place a container between the loose cap sensor (sensor #3) and the reflector. Lower the loose cap sensor with the thumbscrew (turning counter-clockwise) until you see the laser beam on the top of the cap. Raise the loose cap sensor with the thumbscrew (turning clockwise) to the desired height required for a loose cap fault. OPTIONAL EQUIPMENT 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. 35. 36. 37. 38. 39. Turn the conveyor on. Push RUN/SETUP on the sealer power supply. There should be an encoder reference number on the 3-digit display and the green setup light is on. Place a good container with a cap and foil on the conveyor and let it pass through all of the sensors. As the container passes by the entrance sensor (sensor #1) the yellow stalled bottle fault light on the sealer display panel will flash. As the container passes by the exit sensor (sensor #2) the yellow stalled bottle fault light on the sealer display panel will flash. As the container passes by the foil sensor (sensor #4) the yellow missing foil fault light on the sealer display panel will flash. The yellow loose cap fault light will not illuminate during setup. If any of these lights did not flash, there is a problem with the sensors (alignment, power, etc). Push RUN/SETUP on the sealer power supply. The green setup light will go out. If the stalled bottle fault, loose cap fault, or missing foil fault lights are on at this time, then the setup is invalid. Readjust the sensors and re-run the setup procedure. Start the sealer power supply. Run a good container through the sensors to verify the operation. No faults should occur. Run a container through the sensors with out a foil to verify a foil fault condition. The missing foil fault light should come on. Run a container through the sensors with a loose cap to verify a loose cap condition. The loose cap fault light should come on. Run a container through the entrance sensor only. Remove the container before it gets to the exit sensor. The stalled bottle fault light should come on and the sealer will shut off. Clear all of the bottles from the sensor area. Push RESET on the sealer power supply. Start the sealer power supply. The zero speed fault light will illuminate when the encoder reference number is below 40. The setup of the detection system is complete. If at anytime the container size changes or the sensor are adjusted a setup must be performed. 31 OPTIONAL EQUIPMENT Figure 10 32 Encoder Mounting Figure 11 POWER S UPPLY S TAND MUS T BE LOWERED BEFORE MOVING MACHINE CAUTION 4 75 IN D U S TR IALD R IVE H AR T LA N D , W I53029 ( 262) 912- 7200 OPTIONAL EQUIPMENT Typical Bottle and Cap Detection System with Reject & In-feed Bottle Stop 33 OPTIONAL EQUIPMENT Pneumatic Reject A pneumatic reject is available to work in conjunction with the missing foil and/or loose cap detection system. The reject is activated whenever these faults occur. The reject cylinder bracket is simply mounted to the portable stand. The reject signal is determined by the sensor system described above. A source of clean, dry compressed air of at least 80 psi is required to operate the cylinder. Please see the reject setup instructions below to adjust the operation of the pneumatic reject. Setup and Operation 1. 2. 3. 4. Mount the reject tray to the conveyor. Attach the airline to the pneumatic solenoid that is located under the sealer power supply. A ¼ airline fitting is supplied. A source of clean, dry compressed air of at least 80 psi is required to operate the pneumatic cylinder. Route the cables from the sealer power supply to the two photoelectric sensors (reject verification sensors #6) on the reject tray. It does not matter which cable connects to which sensor. Ensure that the cables will not get entangled in the conveyor or any other moving part. Adjust the timed contacts. See the reject setup instructions below to adjust the operation of the pneumatic reject. Reject Control Setup To setup the timed contact closure for an external reject mechanism, press the Run/Setup button on the operator panel. The Setup LED on the operator panel will illuminate. Press the Power button. This readout represents the number of encoder pulses that the relay contact at terminals [83] and [84] will remain closed for or Duration. To adjust this value (1-999), use the Duration up/down buttons. The Duration value is measured in encoder pulses and must be determined by the formula shown below. It should be set equal to but not greater than the equivalent encoder pulses of one container plus the minimum container spacing as shown in figure 13 on page 36. Duration Value = PPR / ( 3.1416*( OD + .5 ) ) * ( Container Width + Spacing ) OD (inches) - Outside Diameter of the conveyor sprocket driving the encoder. See Figure 12. PPR - Encoder pulses per revolution. Container Width plus Spacing between containers in inches. See Figure 13. EXAMPLE: Lets assume that you have a Sprocket Outside Diameter of 5 inches, a 360 ppr encoder, a container width of 2 inches, and a space between containers of 1 inch. 34 OPTIONAL EQUIPMENT Since OD + .5 = 5.5 inches Container Width + Spacing = 3 inches PPR = 360 Then 5.5 X 3.1416 = 17.28 And 360 / 17.28 = 20.83 And 20.83 X 3 = or Encoder pulses per linear inch of conveyor travel. Duration Value = 62.5 Adjust the Duration value to 62 or less. With the Setup LED illuminated, press the Alarm button to view the reject delay. This number represents the number of encoder pulses that the relay contact will be delayed in closing. The delay is from the point of sensing to the reject mechanism. To adjust this value (1-999), use the Delay up/down buttons. Use the encoder pulses per inch calculated above to set the delay value. To test the reject parameters, remove the cap from a container and place the container on the conveyor ahead of the sealing coil and sensors. Adjust the reject parameters and repeat until the reject mechanism expels the container as desired. Replace the cap on the container and run the container through the sensor system again. Press the Run/Setup button to return to the run mode. The Setup LED should now extinguish. If neither of the reject parameters were altered, the Missing Foil Fault indicator will illuminate. Press the reset button to turn off the fault light and the system is ready to operate. Figure 12 Conveyor Sprocket Diameter 35 OPTIONAL EQUIPMENT Figure 13 - Setting Container Spacing The reject verification detection system is used to verify that a container has been removed from the conveyor once the system has decided to reject it. This system consists of a sensor placed at the entrance of the reject tray. If a reject verification has not been detected after a reject, the power supply will turn off, the Reject Fault LED on the front panel will illuminate and the reject fault relay will be energized. To reset this fault and restart the power supply, the RESET or STOP button must be pressed. The system will wait approximately 600ms after the reject relay is de-energized or until the next reject (whichever is shorter) to detect the container exiting the conveyor before issuing a fault. A Reject Fault may also occur if the reject verify sensor is blocked. In Setup mode, the Reject Fault LED on the front panel will illuminate when the reject verification sensor is blocked. In-feed Bottle Stop The in-feed bottle stop is an air-actuated gate that stops bottles from entering an inactive sealing area when the machine is in STOP mode or the power is turned off. This eliminates the risk of 36 OPTIONAL EQUIPMENT unsealed product getting through production lines. It works directly with the LOS (loss of seal indicator) built-in to the induction sealer's power supply. The pneumatic mechanism actuates a 5" stroke cylinder that blocks passage of bottles under the sealing head. The In-feed bottle stop gates incoming bottles when there is an alarm condition or there is no energy to the sealing coil (head). If the sealing energy drops below the operator s output set point, causing an inactive sealing area, the gate closes. When the energy returns and is once again above the operator s set point, the gate opens and bottles are free to move into the active sealing area. Tap Selector Switch An output transformer load compensating selector switch is available to change the output taps on the inverter. The switch is located on the back of the inverter enclosure. See Figure 14. The switch is interlocked to the control circuits so the power supply will turn off prior to a tap change. The use of this switch eliminates the need to remove the inverter enclosure cover in order to change taps. 37 OPTIONAL EQUIPMENT Figure 14 Tap Selector Switch IQ/OQ Documentation Installation qualification protocol and operation qualification protocol documents are available for the specific system ordered. These documents are tailored specifically for the customer and equipment purchased. 38 OPTIONAL EQUIPMENT Conveyor System A conveyor is available to attach to the portable coil support. The conveyor is five feet long with a 4.5-inch wide belt and is constructed of stainless steel. A DC motor controller is available in either 120 VAC or 240 VAC input voltage. The controller allows speed control from 0-60 FPM. The conveyor includes single high guide rails. Please see Figure 15. 39 475 IN D U S TR IALD RIVE H A R T LAN D , W I53029 ( 262) 912-7200 OPTIONAL EQUIPMENT Figure 15 40 Conveyor System SERVICE Service Inverter Inspection Maintenance is limited to keeping the front panel and fan filters clean. Use a soft cloth and window cleaner or mild detergent to clean the front panel. Do not use solvent. Solvent will damage the plastic panel overlay. The fan filter located on the supply's right hand side should be cleaned with plant air or vacuumed occasionally. Disconnect incoming power before cleaning. Check the fan for accumulation of dust. Remove any dust carefully with dry compressed air. Troubleshooting Inverter won't start. - If the alarm circuit is being used to interlock the inverter, check the Alarm Fault indicator. The alarm setting must be lower than the power setting. - An external customer interlock may be active. - Check FAULT lights on the inverter. Refer to page 20 to interpret the lights. - Check the control transformer fuse located on the transformer board in the inverter enclosure. - If the inverter shut down due to high temperature, the inverter is not receiving sufficient cooling. The ambient temperature may be too high. Over Volt fault. - Indicates that a voltage surge or other situation has caused an over-voltage condition within the inverter. The inverter will shut down to protect itself. - Loose or open connection between the inverter and the coil. - Output transformer tap is set too high for the coil being used. Under Volt fault. - Check for a short circuit in the cable running to the coil. - Excessive coil loading. Too many bottles under the coil at once. - Indicates that the supply voltage to the inverter has dropped (as in a brownout). The inverter will shut down to prevent the inverter from drawing excessive current. Check the supply voltage. Current fault. 41 SERVICE - Loose connections between the output transformer and the coil. - Excessive coil loading. Too many bottles under the coil at once. Impedance Low indication or insufficient sealing. - Indicates that an impedance mismatch has occurred. This condition occurs when the load on the inverter is higher than it can deliver. Change output transformer tap. (Note: It is normal for the Low Impedance lamp to be lit when the inverter is in Stop mode. It should go out when the Start button is pressed.) Impedance High indication. - If this light should illuminate when the inverter is in Stop mode, it does not indicate a problem. If it illuminates while the inverter is running, there may be a problem inside the inverter or coil. Typically this indicates that a capacitor within the coil assembly has opened up. In this event, please contact Pillar Service. An optical sensor does not function properly. - Switch to Setup mode and check sensor operation. See that the connector is plugged into the correct receptacle. If the sensor is working electrically Move the support bracket to align sensors. Try sensing the bottle instead of the cap. To disable options - To disable the stalled bottle option, change dip switch #1 to the off position. (Dipswitch #1 is located on the display circuit board.) - To disable the foil detector option, change dip switch #2 to the off position. (Dipswitch #2 is located on the display circuit board.) - To disable the loose cap detector option, change dip switch #3 to the off position. (Dipswitch #3 is located on the display circuit board.) - To change the reject position from exit to entrance, change dip switch #4 to the on position. (Dipswitch #4 is located on the display circuit board.) Coil Support Clean the lead screw if it has accumulates dirt. A light application of silicone oil on the screw thread will keep the crank turning smoothly. Do not use cleaners or lubricants that are not compatible with the Delrin slide blocks. Sealing Coil If the coil is routinely mounted and dismounted, check the condition of the locking handle to ensure proper operation, apply light grease when required. 42 SERVICE Check the fan for accumulation of dust.
