
The roller track is to be swiveled by means of a
double acting cylinder.
The signals to extend and to retract are given
from separate push buttons. The cylinder is to
remain in the position indicated by the last signal
until an opposing signal is given.

Transfer of a Part
Project Description:



Using a double acting cylinder, a part is t be
moved from one roller track to another, as part
of a material handling operation.
The operation is to be started used a push
button. An acknowledgment signal is required
when the piston is fully extended to ensure that
the part has been transferred.
The return stroke is to be automatic.


Production parts are moving an actuator away from a
gravity feed magazine toward an assembly device
Two push buttons are to be incorporated in the circuit.
When either of these is actuated, parts are to be feed.
The return stroke is initiated by the actuator after it
reaches the end of the forward rotation.
The forward and return strokes are to be adjustable.
