INFEED AND CENTERING
SYSTEM EV / EVP
The infeed- and centering systems EV / EVP are installed in
front of chipper canters.
Their main task is the optimum
alignment of logs which is particularly complex with logs that, despite their irregular shape, must be
supplied to the chipper canter in a
correct position.
The arrangement and control of the
rollers in the infeed- and centering
systems allow a feeding of logs
with large end first, small end first
or mixed orientation with constant
volume and accuracy.
Various alignment functions and accurate centering guarantee maximum
lumber recovery.
INFEED AND CENTERING SYSTEM EV / EVP
Roller units
The roller units are directly
mounted on supports which
channel the arising forces directly
into the steel support without
any influence on the chain bed.
The roller pairs can optionally be
equipped with servo-hydraulic
adjustment which allows the
sawing of asymmetrical cutting
patterns with primary processing
and a diagonal cant alignment
with secondary processing.
Primary processing
Log rotation
The infeed system for primary processing
is equipped with two pairs of rollers for
rotating the logs into their proper position.
Decisive for an optimum lumber
recovery is the rotating accuracy.
Two pairs of centering rollers and a holddown roller then take and hold the log in
position.
The optional servo-hydraulic side
adjustment of the roller pairs allows the
sawing of asymmetrical cutting patterns
and the usage of the infeed system in
sawlines with merry-go-round system.
The data from a 3D-scanner as well
as the cutting pattern are used for
determining the rotating angle which
is then realized with an accuracy of
S = ± 5°.
Optimum log position
with regards to
cutting pattern
Log rotation also considers negative
influences resulting from the growth
habit of the log.
Secondary processing
Cant alignment
The infeed system for secondary processing feeds the two-sided cant centered and
aligned to the secondary chipper canter.
Split taper or full taper centering,
diagonal alignment or active curve
sawing can be used for feeding the
two-sided cants to the following
chipper canter.
Alignment of the two-sided cant is done
by two pairs of servo-hydraulically positioned centering rollers.
Log position
during scanning
Hold-down rollers hold the cant in position on the chain bed.
The sawline software makes the
decision for the optimum alignment
for each individual log by using the
stored parameters.
Doors at the infeed systems facilitate
the access to the chipper canter for tool
change.
The required gap remains small no
matter which alignment type is
chosen.
