螺旋焊管板宽自动测量装置的设计应用

Design and Application of the Automatic Measure Device to SAWH Pipe Plate Width

为提高螺旋焊管板宽测量的准确性和精度,降低岗位人员劳动强度,消除测量过程中的安全隐患,针对生产中铣边后钢板宽度采用手动测量的现状,设计了一套板宽自动测量装置。该装置通过基恩士激光位移传感器IG28检测钢板两侧板边位置,采用西门子SM331模拟量模块将检测信号采集到PLC主站中,PLC程序对这些信号进行逻辑判断,从而计算出钢板的实时宽度。利用Wincc Flexible组态软件对钢板的实时宽度进行显示,并设置每种规格钢板宽度的上限、下限值,超限时给予报警提示,在触摸屏上显示出来。实际应用表明,该系统运行稳定,测量数据准确,测量误差在±0.5 mm。

In order to improve the accuracy and precision of spiral welded pipe plate width measurement, reduce staff labor intensity, eliminate the potential safety hazard in the process of measurement, aiming at the current status of manual measuring steel plate width after edge milling in production, a set of plate width automatic measurement device was designed.The device detected the edge position of steel plate both sides by adopting IG28 keyence laser displacement sensor, using Siemens SM331 analog module to acquire the signal to the PLC master station, the PLC program conducted logical judgment for these signals, and calculated the real-time width of steel plate. The Wincc Flexible configuration software was used to display the real-time width of steel plate, set the upper limit and lower limit of each type of steel plate width, an alarm will be given and be displayed on the touch screen if the setting is ultralimit. The actual use showed that this device runs stably,measurement data is accurate, and the measurement deviation is within ±0.5 mm.
