Abstract
Tamil Nadu Newsprint and Papers Limited (TNPL) produces sheet bundle which is called ream can be stored in ASRS (Automatic Storage and Retrieval System) of 7000 tons capacity. Reams which are stored in ASRS can be retrieved and ready for loading point at any time. AS/RS system process is controlled by PLC (Programmable Logic Controller using the PLC process can be controlled manually and automatically as well .In TNPL finishing house area, the reams are packed manually by using brown sheet and being sent to the shrink wrapping machine. In which reams are packed by polythene cover. A single ream bundle contains 500 sheets and 4 or 5 reams are sent for eight fans for reams packing operation. From shrink wrapping machine the packed reams are collected and fed in to the ASRS input conveyor manually. In our project the system eliminates manual handling and will be controlled by PLC with automation and manual control. By extending the output conveyor from shrink wrapping machine reams are pushed to the next perpendicular conveyor using hydraulic pusher and collected by input conveyor of AS/RS. The system also comprises storage conveyor to control the ream flow during maximum production. This system will produce the time consumption and manual efforts.
