ABSTRACT:
A depalletizer and pallet stacking system includes an inlet station which an elevatable U-shaped loaded pallet support frame which permits a forklift unit to be lowered to deposit a loaded pallet with tiers of articles thereon. The loaded pallet support frame rises in steps to move the remaining uppermost tier of articles opposite the inlet end of an elevated horizontally extending conveyor. A shuttle carriage supported above the inlet station carries article gripping units each of which includes horizontally spaced article end hunting clamping members which come together to clamp an associated row of articles of widely varying size with the corresponding articles in the various rows being preferably laterally aligned. The shuttle carriage sequentially delivers each uppermost tier of articles to the inlet end of the conveyor, and the loaded pallet support means then lowers to deliver the empty pallet upon a pallet stacking support means which has been moved into an extended position to receive the pallet. The pallet stacking support means then retracts to a position below the inlet end of the conveyor and upon subsequent return extended to its position drops the pallet thereon upon a stack of empty pallets therebelow.
