Definitions

  • the invention relates to a device for transferring workpieces through a Sequence of processing stations of a press, a simulator or the like or set-up machine according to the one defined in the preamble of claim 1 Art.
  • Such transfer devices are used in presses, step presses, press lines, but also in simulators for moving workpieces, in the latter application used to set up a press.
  • DE-A1- 43 10 057 describes a device for transferring workpieces known by a sequence of processing stations in which the motion drive the longitudinal extent of transport rails is carried out by at least one motor, which acts by means of a gear on a gearwheel that is aligned in the longitudinal direction the transport rail extending rack cooperates, being on the rack a tap point is formed in an area remote from the transport rails, in which is coupled to a coupling rod with one end part, the other end part to the Transport rail is articulated.
  • the drive devices can be used for the individual directions of movement
  • the transport rails are made by motors that are clock-dependent Synchronous operation are electrically coupled together.
  • the additional transverse drives to be provided which are synchronized with that in a lock case the drive motor arranged for the horizontal movement of the transport rails act, include canting of the crossbar in its guide rails out.
  • the drive devices can not simple coupling links, such as rods, connected to the transport rails become. Unbalanced movements lead to a wrong one, from the transfer movement predefined storage or removal position for the workpieces and tilting and tensioning of the coupling and guiding means.
  • the present invention relates to a device for transferring workpieces according to the preamble of claim 1 based on the problem avoid that arise when the transport rails move on one in one vertical level circular orbit.
  • the direction of flow of workpieces through the press 1 is through a Arrow indicated.
  • Gripping devices 3 are known on the transport rails 2 Kind attached, e.g. B. pliers, suction cups or the like.
  • lock boxes 4 of the press 1 there are drive devices for movements of the transport rails 2 in the transverse direction, i.e. towards each other in a horizontal plane, and arranged for movements in the vertical direction.
  • the longitudinal movements of the transport rails 2 are from Drive devices 5, which carriage 6 move that in linear guides parallel to the direction of flow are movable.
  • the cross members 7 are in linear guides 8 stored.
  • the trusses 7 are of an additional Transverse drive 9 synchronized with the movement of the Transport rails 2 moved.
  • FIG. 1 A connection between the trusses 7 and the Transport rails 2 are carried out schematically in FIG. 1 shown compensation guides 10, which in Figures 2 and 3 are shown in more detail.
  • Each Compensating guide has two struts 11, 12, which on the one hand on the truss side, i.e. on the the traverse 7 facing side, via an upper Articulation point 15 and a lower articulation point 16 with the traverse 7 and on the other hand via articulation points 17, 18 with a triangular double-armed Tab 13 are hinged, as in Fig. 2nd and 3.
  • FIGs. 4 and 5 A second embodiment of a compensation guide is shown in Figs. 4 and 5. Already in connection with the description of the previous Reference numerals introduced in the figures are intended below can be used for the same components.
  • a straight tab 20 is used, on the The struts each end at the articulation points 17, 18 11 and 12 are articulated, while the Transport rails 2 facing ends of the struts 11th and 12 via the upper articulation point 15 and the lower one Articulation point 16 with the crossbar 7 articulated are.
  • the straight tab 20 itself is centered over the third Articulation point 19 with the transport rail 2 articulated connected.
