摘要
针对复合胶条的生产线,设计了以西门子S7-200PLC为核心的控制系统。PLC输出模拟量控制变频器的频率以实现多台电机的同步控制,胶条的垂度由光电开关检测,PLC内部控制算法保证胶条的垂度在一定范围内。该系统操作方便,可靠性高,得到了实际应用。
A control system is designed for composite rubber strip product line, adopting Siemens S7-200 as the core. The frequency of converter is controlled by the analog quantity of PLC. Thus the synchrocontrol of multiply motors is realized. The drop of the rubber strip is detected by photoelectricity switch. The drop of the rubber strip is controlled within certain scope by the control algorithm in PLC. The system is easily operated, and has higher reliability. It has been applied in the factory.
