BEAM TRANSFER MECHANISM

Beam transfer mechanism

A beam-type transfer mechanism for moving workpieces step by step along a row of stations through the dies of a press to progressively form a blank into a finished part. A pair of laterally spaced beams extend parallel to the row of stations, having opposed work holding fixtures cooperable to grip the workpiece. The beams are movable in operation laterally toward and away from each other, vertically up and down, and longitudinally, to simultaneously advance the workpieces one step at a time from station to station. The dies would ordinarily be removable and replaceable through the front of the press except for one of the beams which occupies and obstructing position throughout its entire operative movement. Means are provided to lift the beams sufficiently to enable the removal and replacement of the dies through the front of the press without obstruction.

A transfer mechanism for transferring a workpiece between dies in a pressing machine, whose ram is operated by a crank mechanism, has gripping jaws driven from the crank, said jaws moving in a plane normal to the die axis. Jaws 6 are traversed in direction S (Fig. 2) by moving shafts 12 longitudinally, and transverse gripping motion is applied by rotation of shafts 12 which carry pinions meshing with racks in the underface of each gripper 6. Both axial displacement and rotation of the shafts 12 is derived from an eccentric pin 25 (Fig. 3) mounted on one of the press actuating connecting rods 22. Gripping movement of the jaws.-Movement of the pin 25 (Fig. 3) about an elliptical path e causes the ends of rocker 34 to oscillate about a centre 35 which, through link 36 and linkage 38, 39, 40 results in oscillatory rotation of the two shafts 40.

Transportation method for transferring workpieces between several successive stages of a machining device.

Bei einem Transportverfahren zum Umsetzen von Werkstücken zwischen mehreren aufeinanderfolgenden Stufen einer Bearbeitungseinrichtung, insbesondere einer Umformeinrichtung, werden Werkstücke jeweils gleichzeitig mittels mehrerer gemeinsam beweglicher Greifwerkzeuge in einem Transportzyklus von einer Stufe zur jeweils nächstfolgenden Stufe der Bearbeitungseinrichtung transportiert. Beim Vorliegen einer Prozessstörung wird der Transportzyklus unterbrochen und die Greifwerkzeuge mit den Werkstücken werden in eine Warteposition (27), in welcher die Werkstücke ausserhalb des Wirkungsbereichs von Bearbeitungswerkzeugen der Stufen der Bearbeitungseinrichtung sind, bewegt. Nach Wegfall der Prozessstörung wird der Transportzyklus der Werkstücke wieder aufgenommen. Durch die Bewegung der Greifwerkzeuge in eine sichere Warteposition ausserhalb des Wirkungsbereichs der Bearbeitungswerkzeuge der Stufen können Folgeschäden der Prozessstörung verhindert werden. In a transport method for converting workpieces between a plurality of successive stages of a processing device, in particular a forming device, workpieces are each transported simultaneously by means of a plurality of jointly movable gripper tools in a transport cycle from one stage to each next stage of the processing device. In the presence of a process disturbance, the transport cycle is interrupted and the gripping tools with the workpieces are moved to a waiting position (27) in which the workpieces are outside the working range of processing tools of the stages of the processing device. After elimination of the process fault, the transport cycle of the workpieces is resumed. The movement of the gripper tools into a safe waiting position outside the effective range of the processing tools of the stages can prevent consequential damage to the process disturbance.

In the embodiment two feed rails are operated by the followers on a press, Fig. 1, for making can lids with tear-off strips from strip material, the feed rails carrying pockets into which the parts stamped out are ejected during descent of the press-tools 21-30. These are mounted on rams 9, 10, 35, 36 driven, through eccentrics and connecting rods, from a shaft 4 which also drives the drum cam 38 through gearings 39, 40. During ascent of the rams the blanks are lifted out by the pockets and moved against top tools mounted on a head plate 3. The rollers 43, 44 are mounted on a bolt 45 moved axially by a nut 46 to take up play and prevented by a key 49 from rotating. The rails 47 are guided by cylindrical and bevel rollers (52, 53), Fig. 3 (not shown), on eccentric bolts.

Supplying apparatus of materials to press

Material is fed to a high-speed press by an arrangement in which the carry-out arm for pressed material is in a higher plane than that in which the carry in arm for new material is turned. The arms move pivotally in a horizontal direction and linearly in a vertical direction. The fulcrum for pivoting is mounted on a rear surface of the press bolster. The dead point of the carry-in arm is at the end of in-feeding and that for the carry-out arm is at the start of out- feeding. Movements of the arms are timed so that the materials fed in and taken out are overlapped vertically in a position above a lower press die.
