Operator-free fabric web inspection system |
摘要 |
A moving fabric web vision inspection system. The apparatus includes at least two electronic cameras on one side of the moving fabric web for measuring the light intensity of a predetermined area of the moving fabric web. A high frequency, backlight, contrast panel on the other side of the moving fabric web provides reference point for the cameras to detect a defect. A controller connected to each of the electronic cameras generates a stop signal if the light intensity of the predetermined area of the moving fabric web deviates from a predetermined value. The predetermined value corresponds to a detected defect in the moving fabric web. Finally, a repair station downstream from the cameras allows an operator to repair a defect detected by the vision inspection system.
