Abstract
Abstract Conveyor system with plural branches and return path portions for operation in an overall closed loop configuration, there being pallets on the conveyor system circulating in the closed loop and receiving individual items of load to be transported, the conveyor system having individual loading stations for pallets and unloading stations for loaded pallets, from which the empty pallets return to the loading stations. The closed loop including a portion of the conveyor system that is common for return of pallets for several of the unloading stations to several of the loading stations. A pallet stacking station is disposed behind unloading stations for feeding stacks of empty pallets into that common portion, and a pallet unstacking station is disposed in front of the loading stations, receiving stacks of empty pallets and unstacking them for individual availability of emtpy pallets in the loading stations, so that only loaded pallets circulate in the system, loaded either with load proper or with other, empty pallets.
