摘要
为实现针对造纸机切纸工段的精确控制,提出了一套基于PLC(可编程控制器)的电气控制系统。该系统主要由SIMENS S7-200型PLC、SIMENS MM440型变频器和OMRON E6B2-CWZ6C型编码器所组成,通过变频器和编码器相结合的方式实现对于电机转速的控制。在软件设计方面,根据切纸工段的一般工艺流程建立主控制程序,并根据主控制程序的运行流程组建切纸机电气控制系统触摸屏幕控制界面,帮助造纸企业实现造纸机切纸工段的自动化电气控制。
In order to achieve precise control of the paper cutting section of a paper machine,this study proposes an electrical control system based on PLC(Programmable Logic Controller).The system is mainly composed of SIMENS S7-200 PLC,SIMENS MM440 frequency converter,and OMRON E6B2-CWZ6C encoder.The motor speed is controlled through a combination of frequency converter and encoder.In terms of software design,the main control program is established according to the general process flow of the paper cutting section.And the touch screen control interface of the electrical control system of the paper cutter is established according to the operation flow of the main control program to help the paper enterprises achieve automatic electrical control of the paper cutting section of the paper machine.
