一、概述西德Ramisch公司在生产PVC彩色发泡地毯时,有涂复线、印花线和发泡线三条主生产线,每条线上有两套纠偏装置,防止地毯在生产运行中的偏移。涂复线和发泡线采用光电纠偏装置,印花线采用气液纠偏装置。光电纠偏装置,是采用光电检测,利用检测后的电信号控制伺服电机驱动纠偏机构。这种装置的特点:信号传递快、发射器 I. Overview In the production of PVC colored foamed carpets, West Germany Ramisch Company has three main production lines, namely coated lines, printing lines and foaming lines. There are two sets of corrective devices on each line to prevent the displacement of carpets during production. Coating line and foaming line adopt photoelectric correction device, printing line uses gas-liquid deviation correction device. The photoelectric correcting device adopts photoelectric detection, and uses the detected electric signal to control the servo motor to drive the correcting mechanism. This device features: fast signal transmission, transmitter
