  • Automatic selection apparatus of sheet material
    Patent number: 5115144
    Abstract: An automatic selection apparatus for sheet material can automatically distinguish whether sheet materials such as sheets of paper are good or bad. While the sheet materials are carried one by one in the direction perpendicular to the flow direction in the manufacturing process or working process of the sheet materials with a leading edge thereof being held by a gripper, an optical type defect detection device detects a defect in the sheet material. Accordingly, vibration of the sheet material is avoided and the defect can be accurately detected. A controller receives a signal from the defect detection device and drives a switching device which opens and closes the gripper at a defective sheet discharged portion or a good sheet stacked portion.
