control for repetitive machinery operations in industrial
environments can be extremely boring for human operators
but make ideal tasks for computer control. The following
is an example of a custom machine control system developed
Cut-To-Length Wood Tape
company that produces wood tape products for a variety of applications
had one customer that needed strips cut to specific lengths
without any seams. The first phase of manufacturing creates
large rolls of wide strips with seams throughout the roll. Previously
they passed these wide rolls through a spliter that gave them
the width they needed. Then they hand cut the strips to the
required length and eliminated seams. Their problem was this
operation was too labor intensive and they could not keep up
with their orders.
Collaborating with a mechanical engineer we designed and built
a machine that automated the process completely. The machine
included an LCD display and keypad interface that permits an
operator to enter the desired length and the number of pieces
required for each order. A single axis of motion control advances
the material through the machine while measuring the length.
At the specified length the advancement of the material is paused
long enough to make a cut.
sensor checks for changes in the amount of reflected light that
indicate a seam. Once a seam has been advanced past the cutting
mechanism another cut is made. After a seam has been removed
the measuring counter is reset to zero to begin measuring for
the next piece.
machine was originally commissioned as a prototype machine to
prove the design, but it worked so well it was put to work in
