1365304 Feeding workpieces to presses L DYCHE 5 Aug 1971 [11 Aug 1970] 38619/70 Heading B3W Mechanism for feeding workpieces singly to a press comprises a slide reciprocable along a guider to move support means carried by the slide between an unloading position in which the outer, workpiece-carrying end of the supportmeans is above a fixed die of the press and a loading position in which the said end is removed from the die, the guide being pivoted upwardly from its normal horizontal position to raise the slide for travel from the loading to the unloading position and lowered when the slide is in the unloading position to deposit the workpieoe on the die. As shown, arms 14 carrying workpiece support plates 14a are pivotable by a double acting cylinder unit 18 about vertical pins 15 on a plate 15A mounted on a slide 13 for vertical, lateral and longitudinal movement relative thereto. The slide is reciprocable along a guide 12 by a double acting cylinder 19. The guide 12 is itself pivotable by means of a single acting cylinder limit (27), Fig. 3 (not shown), about horizontal pivots supported by lugs 11. With the guide 12 horizontal and the slide retracted, a workpiece is dropped into the recess 14b between the plates 14a so that an enlarged portion of the workpiece rests on the plates. The guide is pivoted to raise the workpiece, the slide is moved along the guide until the workpiece is above the lower die of the press. The guide is pivoted to lower the workpiece on to the die and the arms 14 are pivoted outwardly about axes 15. As the slide is retracted, the arms 14 move together again. A pneumatic valve system for synchronizing operation of the feed mechanism with the operation of the press is described. Instead of arms 14, a single arm may be provided having a longitudinal slot at its outer end with a narrowed mouth through which a workpiece having an enlarged upper end is passed to locate the enlarged end in a recess around the slot.
