<p>PURPOSE:To prevent that a top thin plates stichs to a lower side already separated and that the two thin plates are picked up together by stopping lowering of a suction pad, and then raising the thin plate with respect to the suction pad. CONSTITUTION:A vertically moving cylinder 4 is operated to lower the suction pad 5 of a suction unit 3 to a predetermined position, and to the state capable of sucking. A laminated thin plate 1 in a cassette 2 is raised by a reflow 6 in this state, and the air is injected from an air nozzle 8 in synchronization with the raising. As a result, the plate 1 of the uppermost side is separated by the air injection force, and sucked by a suction pad 5. When it is detected by a suction detecting mechanism, the plate 1 is lowerd by the reflow 6, the air injection is thereafter continued for several seconds, and the unit 3 is raised. Thus, there is no possibility that the sucked plate 1 sticks to the separated plate 1 of the lower side, thereby preventing picking-up of two plates.</p> |
