AUTOMATED STORAGE AND RETRIEVAL SYSTEM USING PLC INTEGRATION
Abstract
Tamil Nadu Newsprint and Papers Limited (TNPL), produces sheet bundle which is called ream can be stored in Automatic Storage and Retrieval System (AS/RS) of 7000 tons capacity. Reams which are stored in AS/RS can be retrieved and ready for loading point at any time. AS/RS system process is controlled by Programmable Logic Controller (PLC) using the PLC process can be controlled manually and automatically as well.The main aim this paper is 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. Whereas, adding intermediate path between packing and storage section, will reduce the paper damage and give full efficient work throughout the day. Due to this, the manual effort will be reduced and the paper mill will get an immense production
