ABSTRACT:
An independent pallet delivery system for transporting pallets through a block forming machine that forms concrete blocks on a pallet. The systems includes a pallet magazine for storing a plurality of pallets therein. A conveyor belt formed with a pulley system for transporting the pallets. A pallet pick-up position which receives a pallet from the pallet magazine and places the pallet in a holding position above the conveyor. A jacking assembly is provided to raise that conveyor to engage with the pallet and deliver the pallet to the block forming machine. The block forming machine lifts the empty pallet and forms a molded block thereon. As the block forming machine lowers the pallet towards the conveyor, the jacking assembly lowers the conveyor to cushion the return of the pallet having the molded cement blocks thereon. The pallet with the molded concrete blocks is placed on the conveyor and a takeaway conveyor which move at essentially the same speed and outputs the pallet to an automated conveyor.
