ABSTRACT
The packageing machinery is a kind of steping complicated machine tools.Applying Programmable Logic Controller to the control system of packageing machinery can simplify the system design and raise the effectiveness and reliability of the system.In this paper,the control systems of chemical fiber baler are used as a example.At first it introduces the characteristics,method of designing the program,and method of editing the program of Mitsubishi FX2N.The method of designing and editing the program include the Experience Designing Method ,Sequencely Controlling Designing Method,and STL(Step Ladder Instruction).Then,it concretely analyses and introduces the electrical construct,electrical feature,and program of the control systems of chemical fiber baler.At last it introduces using the personal computer to input the program into the Programmable Packageing Machinery.The used software is SWOPC-FXGP/WIN-C of Mitsubishi company.
