Figure 4.14 Palletizer with Soft Start and Preset Slow Speed Option
Problem: Stacks of paper on a conveyor were moved to a bander
and then moved through the bander process onto a skid.
When the papers were loose, a controlled low speed
acceleration into the bander was required. After the
papers were bound, a soft start was needed to keep the
bundles from falling off the palletizer. The expense of a
variable frequency drive to control the motor speed was
not feasible.
Solution: The SMC Dialog Plus controller with the Preset Slow
Speed option was installed, eliminating the need for
frequent jogging of the conveyor to align the load with
the bander. The loose papers were moved into the bander
at 15% of full speed. A Soft Start was used to accelerat
the motor to full speed, and load the bound stacks on th
skid. The SMC Dialog Plus controller was a cost
effective method of achieving the results required by the
application.
