ABSTRACT:
Material handling apparatus and methods, especially for use with loose stacks of paper and the like in pallets. The invention includes depalletizing apparatus, distributing apparatus, and hopper loading apparatus; and material handling apparatus for transporting material between the depalletizing apparatus, the distributing apparatus, and the hopper loading apparatus. The depalletizing operation includes lateral sliding of layers of a pallet load onto a removal conveyor and then away from the pallet. Significant advantages are achieved by using a special spacing sheet in the pallet load instead of slip sheets and tie sheets. Fingers on the pusher extend below individual layers of the load and into the channels in a spacing sheet, effecting the removal of even the bottom layer of papers in a stack. Similar use of fingers and channels applies to operation of the hopper loader and its control of the bottom papers in the stack. Accumulator apparatus is used as desired for staging appropriate materials throughout the system. Spacing sheets and empty pallets are automatically removed from the depalletizer, to collection and storage areas.
