PURPOSE:To increase a production speed in a press stage, by surely conveying blank materials punched in the first and second blanking positions sheet by sheet to a prescribed position in an idle stage with a receiver moved in accordance with lifting of a press slide. CONSTITUTION:A blank material 5 punched in the first blanking position 20A is dropped onto a receiver 29 of a carriage 21. Then the carriage 21 is moved in the direction of an arrow head (a) synchronously with lifting of a slide 8, and the receiver 29 is moved to the first idle position 6A at the top dead center of the slide 8 to deliver the blank material to an idle conveyer device 15 in a press process. Then synchronouly with descending of the slide 8, the carriage 21 is moved in the direction of an arrow head (b) and displaced to the second blanking position 20B, and the second blank material 5 is punched and accepted by the receiver 29, again moved to the position 6A by a reverse procedure and delivered to the device 15. Hereafter, each blank material 5 is conveyed to a molding press stage 43 through a receiving bed 13. |
