The Realization of the Control System of Storage Stacker Based on PLC
Abstract In the automated multi-layered storehouse the most important equipment is the tunnel stacker, the tunnel stacker is the realization entire warehouse system “automatic” the function essentional equipment. The development of the automated warehouse based on the tunnel stacker. This paper describes the realization for the control system of storage stacker based on PLC. Unified the PLC technology and the frequency conversion control technology, the change of the speed based on the transducer, as well as combined the photoelectric-encoder to constructs the system. It can achieve some functions. These functions include three-dimensional movement, exactitude orientation, emergency stop and alarm.
