These conventional palletizers are ideal for the high-speed palletizing of bags and boxes. High-level palletizers work by first forming each row, which is then moved onto the layer forming platform. The pallet is on an elevator under the platform and moves into place. Once a layer is complete, the layer is squared up with powered guides and the platform opens to deposit the layer onto the pallet. When layer count is achieved, the pallet is discharged from the palletizer and a fresh pallet moved into position, while a new layer begins formation.
