YJ17卷制成型机电控系统分析

Design and Research on the Electronic Control System for Roll-formed Machine YJ17

YJ17卷制成型机引进德国先进的PROTOS70技术,采用西门子PLC S7-400控制系统,PLC内部的启动程序、纸盘转换程序、张紧力控制程序等驱动外部的电气设备,实现主驱动装置控制、接纸控制、烟纸张紧力控制等功能。以封口器控制为例,阐述了启动程序的7步工作顺序由烟条时钟脉冲RCP和3个级联计数器CTR来延时,实现不同工作状态有顺序地稳步进行。实际运行证明:整个系统具有稳定性好、有效作业率高、剔除点准确等特点。

YJ17 Roll-Formed Machine is high-speed roll-formed device for the domestic mainstream production of cigarettes for introducing Germany advanced PROTOS70 technology.Siemens PLC S7-400 control system is adopted for YJ17 Roll-Formed Machine.Due to combining PLC’s Internal start-up program, paper-tray conversion program, tension control program etc with external electrical equipment, the system can realize main drive control, splicing control, cigarette papers’tension control etc.In the case of sealing device control, Seven-steps work order in start-up program is delayed by cigarette clock pulse RCP and three cascaded counters CTR, and it achieves that different working conditions are sequentially steady. Actually the whole system has good stability, high efficiency operation, accurate excluding points and so on.
