The work aims to develop a new control system of automatic sealing capping machine. An industrial touch-screen control system with ARM9 S3C2416 microprocessor as the core was designed and it constituted an integrated device in combination with servo driver, frequency converter and relay. The working process, control timing scheme and procedure flow chart, as well as working sequence of single-tube mode and dual-tube mode of the sealing capping machine were introduced in detail. The scheme in which software timer was used to achieve multi-functional timing was proposed. With such scheme, the real-time communication interruption and other problems of motor speed and capping torque were solved. After replacing the traditional PLC control with ARM9 embedded system, the control system is characterized by stable performance, fast response, high control accuracy and friendly man-machine interface. With single-tube/dual-tube modes, the production speed is accelerated.
