一种控制切纸机的PLC程序设计

Design of PLC Ladder Program for Paper Cutting Machine

以切纸机为控制对象,采用西门子S7-1200 PLC进行梯形图编程,设计出一套程序实现切纸机对卷筒纸任意长度、任意数量的纸带切割,程序包括自动控制程序、手动控制程序。同时,采用西门子SIMATIC精简系列HMI触摸屏进行画面组态,实现在HMI触摸屏上完成参数设置以及对切纸机的各项操作。经过实际运行,该PLC梯形图程序能让切纸机切割出符合要求的纸带。

This paper designs ladder program using Siemens S7-1200 PLC and interface on Siemens SIMATIC HMI to control paper cutting machine.This ladder program can make paper cutting machine cut rolled paper into paper belts whose lengths and quantities can be pre-set on HMI.The paper belts satisfy the requirements in terms of efficiency and precision.
