Design And Realization Of Control System Of Batch-off Machine

Batch-off machine is an important part in rubber production line. It can press the film through pressing machine. The process is to dip, to cool into dryness, and continuously to swing, fold up or cut into pieces in the batch-off machine. Based on the project, this dissertation uses the Programmable Logic Controller (PLC) and advanced control method to realize the control system, and analyzes synchronous control of velocity between the takeup equipment and hanging equipment.The main work of this dissertation is given as below:1. On the basis of collecting a vast amount of domestic and overseas data, according to customers'requirement, the author designs and makes the mechanical part. The innovation is to add a fixed manipulator to reduce working intensity and improve automatic level.2. Considering the advantage of PLC, the author designs the control system on software and hardware sides, in which PLC input and output wiring, sensor using and so on include. The whole facility is finished the adjustment of machine at last.3. In order to enlarge the production capability and improve the automatic level for some customers, the author also researches synchronous control of velocity between the takeup equipment and hanging equipment. The PID controller based on PLC is used to ensure the consistency of working time to control precision.4. To fit the needs of technical requirement, the author designs the control and monitoring program using Visual C++ which can realize the online velocity, film length and so on. It has data acquisition system. The whole operation system is simple and useful.In all, it gives out certain value to future similar facility and has broad application foreground.
