目的 设计一款集制袋-填充-封合于一体的高速自动化生产设备及其控制系统。方法 采用S7-1200PLC作为控制系统， 并通过触摸屏对封合温度进行调整并在线显示。供料装置采用压缩气体吹气式供料方式， 以实现高速给料。结果 通过PLC高速计数读取旋转编码器转角控制各机构动作的执行， 封合温度采用PID控制， 达到了稳定控制效果。结论 通过PLC与触摸屏的结合使用， 增加了系统的柔性,实现了高速包装。

The study aimed to design an automatic production equipment and its control system which included bag making, filling and sealing. S7-1200PLC was used as the control system of the packaging machine. The touch screen was used to adjust sealing temperature and online display. The feeding device was set using compressed gas of air blowing type to realize high-speed feeding. The execution of each action was controlled through reading the rotary encoder angle by high-speed counting of PLC and the sealing temperature was controlled by PID, thus, the steady control effect was realized. With the use of PLC and touch screen, the flexibility of the system was increased and the high speed packaging was achieved.
