ABSTRACT:
A semi-automatic palletizer is disclosed providing an elevator for positioning pallets below an arranging table to receive layers of arranged articles. As each layer is positioned on a pallet supported by the elevator, the elevator lowers to position the uppermost layer thereon, immediately below the arranging table. A power feed mechanism is provided to automatically position empty pallets on the elevator and for ejecting loaded pallets from the elevator. The feed mechanism includes a fork-type lift which is extended into the pallet, adjacent to the bottommost pallet at the pallet supply position, and which thereafter raises such pallet and all pallets above, clear of the bottom pallet at the supply position. A pusher pushes an empty pallet from the supply position onto the elevator and causes removal of a loaded pallet as the empty pallet is supplied. After retraction of the pusher, the fork lift mechanism lowers the remaining pallets to the supply platform. Rollers on the elevator are provided with a friction drag having a value sufficiently high so that empty pallets remain in proper position on the elevator during loading, but sufficiently low so that a loaded pallet can be easily rolled off of the elevator.
