HOIST / CRANE APPLICATION ON A PALLETIZER
PALLETIZER MEASUREMENT FOR FOOD MANUFACTURERS
LASER RANGEFINDERS VERIFY THE POSITIONS OF PALETTES
A major frozen dough manufacturer automates much of their production and packaging. They use a palletizer to organize cases of product onto a pallet. This robotic machine builds each row of boxes and the position of the moving parts is verified with a laser rangefinder. The sensors report positional feedback to a master PLC so that no boxes are crushed or improperly positioned.
The solution was implemented by a local integrator who chose the eye-safe AR4000-RET rangefinders which had a high frequency response and an analog output 4-20mA signal. The sensors operate in cold ambient temperatures and are impervious to the electromagnetic interference created by the robot’s variable frequency drive motors.
