摘要

Based on the problem that the control system of rotary screen printing machine can not on-line inspect and real-timely adjust off pattern in the process of printing, an automatic inspecting registration system is designed by images of pattern position marks on both sides of fabric in wax dying. The images of pattern position marks before printing are captured by a CCD image sensor, and the real distance about the current pattern and the error between the measured value and the standard value are calculated, which are used to estimate the registration precision and produce the control pulse for regulating the rolling speed. After printing, the effect of dynamic adaptation is given by another CCD image sensor and according to the feedback the secondary adjustment is made. In this way, the closed-loop registration system for rotary screen printing machine is realized that will raise the quality and the productivity of printing.
