The work aims to improve the automation of the pillow type packaging machine and enhance the universality and portability of its control system. With Omron PLC CPU-CJ2M and motion control module CJ1W-NC414 as core of the control system, and in combination with such advanced techniques as servo system and photoelectric sensor, the synchronous control over the three axes of the packaging machine was achieved. As for the temperature control, CJ1W-TC001 temperature control unit was adopted to achieve the precise temperature control over the horizontal and vertical sealing of the packaging machine. Meanwhile, Weinview TK6050IP touch screen was used to monitor in real time, set the parameters of and online display the entire control system. The system successfully achieved the automatic control over the pillow type packaging machine as well as the monitoring of operating state and the setting of packaging parameters. The system has been successfully applied in the three servo pillow type packaging machine, with which the packaging precision, speed and automation of the packaging machine have been improved.
