PURPOSE:To prevent a defective laver sheet from transferring to the next step, by sensing and removing the defective laver sheet with an potical sensor provided at the peripheral position of the laver sheet. CONSTITUTION:A dried laver sheet peeled from a laver reed screen is transferred by a conveyor 1 in the direction of an arrow (a) and stopped by a stopper (S) on a defective laver sheet sensing part 2. When timing sensors 61, 62 and 63 receive light, the laver sheet is judged to be a defective in which the part is damaged. The stopper (S) is lowered to send the laver sheet directly to a stocker 9. Unless any one of the sensors 61, 62 and 63 receives light, sensors 31-36 in which two receptor elements are paired are operated, and the laver sheet without holes is delivered to the direction of an arrow (c) by lifting a roller conveyor 10 above a belt 1'. In the case of the defective laver sheet, the roller conveyor 10 is not lifted, and the stopper (S) is lowered to send the laver sheet to the stocker 9. |
