PURPOSE:To realize saving of the floor space by performing both reciprocating motion of a mobile body and elevating/lowering motion of a feed bar by means of one driving device and giving the feed bar a big reciprocating motion through a small one of the mobile body. CONSTITUTION:A mobile body 4 guided by a machine in the direction of conveyance of raw material and the like is provided with a freely rotatable crankshaft 8, and also provided with a holder 6 which is connected to an eccentric part of said crankshaft 8 through a rod 9 and also guided by means of the mobile body 4 so as to freely go up and down. Further, a feed bar 17 guided by the holder 6 in the direction of conveyance is provided with a holder 18 for the raw material and the like, while a reciprocating belt-like member 15 is provided in the state of being suspended from pulleys 11, 12, 14 provided on the machine so as to rotate freely. Furthermore, member 15 is hung from the shaft 8 and also a brake system is provided to brake the shaft 8, while a stopper 16 is provided on the machine to control movement of the mobile body 4. Thus, the length of the machine in the direction of conveyance is reduced, therefore, an interval between presses is reduced and the floor space can be saved. |
