Abstract
The invnetion is to automatically sort sample sheets from NG sheets with a simple mechanism without damaging any sheet. A web (14A) is cut into the sample sheets and the NG sheets by a cutter (18). Since the sheets are carried while sucked by a suction conveyor (20), they can be consistently carried without any damages. The carried sample sheets are transferred to a stacking table (22). The stacking table (22) is evacuated from a top part of an NG conveyor (46) disposed below the stocking table (22) by an air cylinder (40). By evacuating the stacking table (22), the NG sheets to be carried by the suction conveyor (20) are dropped onto the NG conveyor (46) and stacked. Thus, the sample sheets can be automatically sorted from the NG sheets without taking out the NG sheets from the stacking table (22) one by one.
