The Control System Of Automatic Bagging And Palletizing Line Based On PLC

Most conventional mechanical facilities are machines. They are mechanicalfacilities in the control of electrics, hydraulic pressure and aerodynamic pressure.Automatic control of mechanical facility has replaced manual work step by step.PLC is a late-model automatic equipment . Its development is based on computer technology , automatization technology and communications. At the present,PLC has become the most important automatic equipment and been applied widely , after the development of 30 years. PLC has hold the primacy in the field of industry automatization (PLC,ROBOT,CAD&CAM). The degree and extent of PLC development are the symbols of automatic level in one country.In this paper, I try to bring the completed and detailed idea of design of automatic bagging & palletizing line control system's hardware and software.This article is made up of fife parts of the design. It includes the design of machinery, the aerodynamic system and the control system. It's main functions and hard/software were introduced. This automatic bagging & palletizing line is in the charge of integrated application of PLC.Automatic bagging & palletizing line is used in the industries of petrochemical, fertilizer, food processing, and transportation port etc. It can perform bagging and palletizing automatically for powder and granular materials such as chemical fertilizer, plastic granules (PP/PE/PVC) and grains etc. It is easy for customers to store, transport and sale their products. Automatic bagging & palletizing line consists of auto-weighing bagging machine, auto-bag feed group, sealing system, bag turn down machine, metal detector, sorting machine, jet printer and palletizing machine etc. units. Through programming controller, the whole system process can be automatic controlled. Any process operation troubles, not enough feeds, bag feeding not due or palletizing not in time all can be alarmed by sound or light. It has the advantages of simple operation, reliable and easy maintenance etc. According to the customer's requirements, the system also can be equipped with communication port interface for DCS control, equipped with printer for printing daily, monthly production records, also can be connected with computer or touch screen for auto weighing bagging machine monitoring or intranet network management.
