Definitions

  • the invention relates to a press, multi-stage press or the like. Forming machine of a generic type.
  • the end areas of a press are assigned to the insertion of blanks and the removal of these after shaping.
  • the drive of the transport rails for the transfer movement can be assigned to the removal area of the press.
  • the removal can take place on a conveyor belt.
  • Loading takes place via a blank loader, which is important in terms of size, separating blanks, cleaning and, if necessary, straightening them, orienting and inserting the blanks into a first station of the press, even in the insertion area of the press.
  • the end regions of the transport rails extend into the area of the blank loader in accordance with the transfer stroke. The movement towards each other for gripping the workpieces and the transfer movement result in a significant restriction for the board loader.
  • the documents DE 28 16 928 C2, DE 33 29 900 C2 and EP 0 202 882 A2 show transport rails which extend into the area of the board loader and thus beyond the area for initiating the lifting / lowering movement and the opening / closing movement.
  • the presses shown here have overall solutions for guiding the transport rails, in which the length of the running rails due to the length of the transfer movement is included in the moving part of the guide, that is to say in the transport rail.
  • the transport rails must be made longer by this amount of movement, on the other hand, there are spatial restrictions for the board loader.
  • press stands 1 From the press, four press stands 1 are shown with the means attached to them for the lifting and lowering movement and for the tensioning and releasing movement of transport rails 2.
  • Drive means 6 for the opening / closing movement and drive means 9 for the lifting / lowering movement of the transport rails 2 are attached in each area of a pair of press stands 1. These means act via gears, toothed racks or the like.
  • Means on the transport rails 2 which are mounted horizontally and vertically in rails 8, 11 or 12.
  • the transfer movement is 4, the opening / closing movement is 7, the lifting / lowering movement positioned with 10.
  • the means for these movements are well known in one form or another from the prior art, so that there is no need to go into detail about these means.
  • the area of the transport rails 2 which is assigned to the drive for the transfer movement is generally indicated at 17.
  • the transport rails 2 are mounted on or in guides 13 in the area 18 which is removed from the drive area 17.
  • the guides 13 are displaceable on a cross part 14 in guide strips, as shown at 8 in the region 17, in the opening and closing movement by means of the drive motor 6.
  • the cross bar 14 can be lifted and lowered overall in guide bars 11 by means of the drive motor 9.
  • the transport rails 2 are provided with holding means such as gripping tools 15 or suction bars 16 for gripping and holding workpieces through the processing stages.
  • the suction bars 16 are only hinted at as a variant.
  • the length of the guide 13 for the transport rail 2 is set to the length of the transfer movement plus the required length of the guide or guide means on or in the transport rail 2.
  • two guide means are provided , the arrangement and structure of which can be seen in a preferred embodiment from FIG. 2.
  • the guide 13 is set up as an inner part, the transport rail 2 as an outer part.
  • Running rails or running rails 20 are attached to the guide 13.
  • the transport rail 2 has rollers 21 running thereon as counter-running means.
  • Both the guides 13 and the transport rails 2 can be articulated in hinge bearings or in ball socket bearings or the like. Means.
  • the motion drive in The three axes shown here can thus, as shown, take place via discrete motor control as well as in a curve-guided manner.
  • the length of the guide strips 20 on the guides 13 results here from the length of the transfer movement of the transport rods 2, the distance between the roller means, pairs of rollers 21 in the cutting areas II-II and, if applicable, a selectable oversize.
