变频控制技术在不锈钢钢管自动包装机中的应用

介绍了PLC、HMI和变频器驱动控制技术在不锈钢钢管自动包装机中的应用,自动包装机的组成及工作过程。在成品钢管包装线的电气设计时选用了西门子PLC、HMI和变频器,确定了固定速度切换方案,编制了PLC程序、HMI画面程序,对变频器进行了参数设置和说明。应用PLC、HMI控制技术,解决了变频器运行速度切换问题,保证了钢管的包装质量,实现了包装机的自动控制。

Application of Variable Frequency Control Technique to Automatic Packing Machine for Stainless Steel Pipes

Elaborated here in the assay are the application of PLC,HMI and inverter drive control technique to the automatic packing machine for stainless steel pipes,and the configuration and operation process of the packing machine itself. The PLC,HMI and the inverter made by Siemens are chosen for the electric design for the finished pipe packing line,and the program for fixed speed change-over is determined;the PLC program and the HMI picture program are made;and the data of the inverter are set and described. Thanks to employment of the PLC and HMI control technique,the problem with change-over of the inverter’s running speed is fixed so that steel pipe packing quality is assured,and automatic control of the packing machine realized.
