  • Automated warehouse inloading/outloading storage controller
    Patent number: 5568393
    Abstract: A picking means for picking goods from pallets removed from a storehouse, and a filling means for filling the pallets with incoming goods and storing them in the storehouse, are connected by a pallet transport means. When goods are to be delivered, the storage space created by picking goods from the pallets is detected. Pallets in which storage space is detected are transported by the transport means to the filling means, where they are filled with incoming goods of sizes which match their storage space, and are then stored in the storehouse. Goods are thereby stored in the storehouse promptly, and the filling density in the storehouse is increased.
