Abstract

PURPOSE: To detect defective sheets of laver, by setting a conveyer which can transfer the sheets zigzag vertically in the direction of delivery and in the direction normal to it or in the composite direction and also setting a light emitter and optical senser for checking the zigzag course.
CONSTITUTION: A sheet of dry laver 7 is transferred in the arrow a direction on a conveyer 2, and when its tip intercepts a line, on which a light emitter 8 and optical senser 10 are aligned, immediately after passing on a vertical zigzag path 3, a light 4 is emitted from the emitter 5. If the sheet 7 has any crack, the crack 39 is opened while passing zigzag and the light 4 passing through the crack is received by the senser 6. Then a stopper 24 is turned from its vertical position to tilting position for discharging the sheet of laver from the terminal of the conveyer 2. If the rear end of the sheet does not intercept the light emitted upward from the emitter 8 at the moment when the sheet passes over the emitter 8, the sheet is found short-sized. Then the photosenser 10 is actuated to knock down the stopper 24 for discharging the sheets as defective from the conveyer 2.
