Abstract Hot and cold basket switching is currently dominated by manual handling, labor cost is high, benefit is poor。 Therefore, the design automatic switching, to shorten the production cycle, reduce the production cost, ensure the cold press can work steadily and safely。

Cold press automatic switching mechanism to meet the need to design a basket of reasonable structure, simple and safe operation, easy handling, reduce the cost of the design requirements, reduce the labor intensity of technicians, to ensure the safety and convenient operation; in case of meeting the performance requirements, according to the working environment and cost requirements, the hardware selection and the corresponding

design; PLC control procedures, in order to improve the efficiency of test data and intuitive, more close to the actual production requirements, design the delta PLC control, improve

the speed of data processing, speed up the overall control speed, shorten the production cycle; drawing control system wiring diagram of hardware and software debugging; finally, the unreasonable conduct the basket switching optimization, stable and reliable。 Close to the actual production requirements。

Cold press basket switch design automation can reduce operator labor intensity and improve the safe production and labor conditions; to improve production efficiency, ensure product quality, reduce the production cycle, reduce production costs, and ultimately enhance their competitiveness, so that enterprises to the automatic and intelligent direction。

Keywords: Delta PLC; automation; efficiency; switching basket
