Robotic system for palletizing of heat-shrink film wrapped case packages of yoghurt

The palletizing robot performs palletizing of heat-shrink film wrapped case packages of yoghurt.

The equipment was purchased to replace a worn-out palletizer. Palletizing was done manually during the downtime of the line. A target payback period of three years imposed a constraint on the project budget.

An additional constraint was the limited space in the shop to locate the new equipment.

During the preliminary development, the optimal arrangement was found to meet the target cost of the equipment by having the robot perform three operations — product palletizing, stacking of pallet from the pallet magazine, and laying the spacer.

The industrial robot grips a row of packages at a time to ensure the target output capacity. The row preparation is done with a special device called the layer former.
