The art of creating stable stacks Whether you are palletising bags, pouches, cartons, boxes, pails, buckets or drums, the ultimate stability of your stack is paramount. Of course, you want to be an efficient operation and getting as much product onto the pallet as possible within the appropriate weight and height limits plays a part in this, but not at the detriment of other people’s safety. Outside of these primary aims, other factors to consider are bar code scanning or the ease of picking or de-packing the stack by the customer. Leaving gaps between boxes can help to create a stable stack, and an automated programme can do this repetitive task consistently. Retailers are also calling for more mixed pallet loads in an effort to pare down stockroom inventories. A robot can be configured to differentiate light from heavy packages, which means they can palletise a variety of case sizes of products on one pallet without compromising the stability. base pallet load being sufficiently strong to carry the load of the pallet above. The weight of the upper pallet must be evenly shared by all sides of the bottom stack, which articulated robotic arms can successfully accomplish.
