US Patent 7033130 Depalletizer for a material handling system

A depalletizer includes an input assembly for supporting a loaded pallet loaded with at least one product, a lift assembly, and a product take-away assembly. The input assembly presents the loaded pallet to the lift assembly, which moves the loaded pallet to a product unloading elevation. The product take-away assembly is positioned for receiving a product from the pallet at the unloading elevation. The depalletizer assembly also includes a pallet take-away assembly. After the product is unloaded from the pallet, the lift assembly moves the unloaded pallet to a pallet discharge elevation, where the pallet take-away assembly is positioned to receive an unloaded pallet from the lift assembly.
