Problem: A
brewery in Queensland uses large rolls of shrink wrap
plastic to wrap three six-packs at once at the end of the
filling line. The problem was that since the introduction
of the three bay line there was a large and costly surplus
of shrink wrap which was only wide enough to wrap two
six-packs at a time. The two-bay line couldn't be used
directly as it was slower than the line feeding it and so
the problem arose.
Solution: The line feeding the two bay shrink
wrapper had to be slowed down. By application of a
UNIMETER, the speed of the line could be decreased without
making major changes to the plants operation. The UNIMETER
converted the 0-10V speed control to approximately 0-6.6V
using its span adjust function. Hence the UNIMETER was
used to slow down the line and allow it to run at the same
speed as the slower line, allowing the use of the two bay
shrink wrap.
Benefits: The Brewery managed to significantly
reduce costs by using the left over shrink wrap as a
result of a very basic UNIMETER application. The UNIMETER
allowed changes in the speed of the line feed without
making any changes to the lines control system. Hence in
order to change the wrapping line from three to two or
vice versa it was as simple as the addition or removal of
a UNIMETER.
