Abstract

949,682. Blanks transferring. B. SCHLATTERER. Nov. 10, 1960, No. 38610/60. Heading B3H. A device for feeding workpieces 71 into a press 11, particularly an eccentrically driven press, comprises grippers 70 driven by a carriage 30 which first moves relatively to the grippers and towards the press through a predetermined distance which acting through screw-and-nut mechanism, causes the grippers to close on a workpiece, and then the carriage and grippers move together towards the press; upon the return movement the grippers are first opened and are then moved with the carriage to their initial position. The feed device is adjustably mounted on the press bed and carries a magazine 69 for the workpieces at station a. Carriage 30 is reciprocated along parallel guide rods by a connecting rod 34 attached to a crank-pin on a disc 47. The crank-pin is adjustable radially, Fig. 5 (not shown), for varying the carriage stroke which is indicated on a plate 37. crank disc 47 is driven through a variable-speed belt drive 35, Fig. 5 (not shown), and electromagnetic clutch 52, 54, Fig. 5 (not shown), by and electric motor 36; a brake device is incorporated in the drive. The grippers 70 are adjustably secured to bars 18 mounted for transverse movement on a guide traverse 38. The latter is mounted to slide on the guide rods under restraint of a brake pad 64, Fig. 6 (not shown), and is connected to the carriage 30 by an adjustable lost-motion coupling 32a, 33; during this lost motion which occurs at the beginning of the carriage stroke, the relative movement is converted by a wide pitch screw and nut 28, 31, Fig. 4, into a rotation of a pair of longitudinal shafts which act through pinion and rack mechanisms 26, 27 to produce the transverse movement of the bars 18 for opening and closing the grippers. The nuts 31 are rotatably adjustable in the carriage 30. A longitudinal adjustment 73 for the bars is incorporated with a yielding device and a stop mechanism which operates if the feed encounters an obstruction. Cam-operated contacts, 60, 61, Fig. 2 (not shown), contact engagement and disengagement of the electromagnetic clutch and brake and the starting of the press cycle.
