Palletizing/depalletizing is the process of lifting on or off packages on a pallet. There is a wide selection of products that is used very much today when palletizing e.g. suction cups, large area vacuum gripper systems, or ergonomic handling systems in combination with vacuum pumps. Palletizing machines use vacuum pumps, suction cups and other pneumatic components. These machines typically pick up multiple boxes at a time and place them on a stack or unload from a pallet. Today, because of the high speeds required, robots are often used to accomplish this task. Another vacuum application during this process is the handling of slip sheets or tier sheets that are placed between the layers of packages which have different requirements than handling the boxes.
