The work aims to overcome the slow manual packaging speed and inaesthetic packaging appearance of fruits and vegetables, so as to improve the automation level of the packaging machinery and reduce the packaging machine cost. Firstly, the basic structure and technological process of the fruit and vegetable packaging machine were introduced. Based on that, an automatic fruit and vegetable packaging machine control system focusing on programmable controller (PLC) and touch screen was put forward, and the hardware structure based on PLC and touch screen was discussed in detail. Meanwhile, based on the hardware structure, the software system supporting the packaging machine with respect to its technological process was developed. The control system was simple, easy-to-operate and programmable, and could fully meet the movement control requirements of the automatic packaging machine. With higher reliability and maintainability, the control system significantly improves the packaging efficiency of fruits and vegetables, and the intelligence and automation level of packaging machine.
