Definitions

  • the present invention relates to a method for feeding and feeding a strip into or through a forming tool according to the preamble of claim 1, and a strip feeder for carrying out this method.
  • Processes and strip feeders of this type are e.g. B. from DE-U-8,220,431 or EP-A-0,409,151 known.
  • a revolving conveying element i.e. a belt or a roller, is provided, and these conveying elements, provided that they are provided with a driving finger, have to run back the full way after the gradual advancement of a strip in order to detect a next strut.
  • conveyor rollers are provided, it is hardly possible to move strips or similar parts exactly in all cases, and to bring the rear end thereof close enough to a tool.
  • the aim of the present invention is to avoid the disadvantages mentioned with a simple structure. This goal is achieved according to the characteristics of claims 1 and 3, respectively. Since the finger bar has several fingers in the longitudinal direction or direction of movement, which are preferably at different distances from one another, there is extensive freedom in the program design and only limited, quickly executable steps of, for example, at most 400 mm are required.
  • FIG. 1 shows a forming tool 1, for example for punching out rondelles from strips 2.
  • the strips 2 have the usual shape with wavy sides, from which, with optimal use of the material according to FIG. B. two rows of rondelles offset in the longitudinal and transverse directions can be punched out. However, other processing, for example deformation of the material, can of course also take place.
  • the strip feeder has a finger bar 3, which in the exemplary embodiment is equipped with five resilient fingers or drivers 4-8. In the unloaded state, these fingers protrude under the spring action over the finger bar 3 and can thus grip and take a strip 2 on its rear edge, and the fingers covered by a strip are pressed into the finger bar 3.
  • the foremost finger 8 lies at the front end of the finger rod 3 and can thus move a strip 2 according to FIG. 2 into the last position to cut out the last rondelle or to process the last part in a strip, without colliding with the forming tool.
  • the remaining grid of the strip, from which all parts are punched out, is pulled out of the forming tool by means of a pair of pull-out rollers 9.
  • the strips 2 are individually removed from a magazine 10 by means of a vertical stacker 11 in a known manner and placed on a guide path, not shown, on which they pass through the fingers of the Finger bar 3 can be detected and fed to the forming tool 1.
  • the finger rod 3 is connected to a programmable linear drive 12 which can execute an entire program of any forward and return strokes, as indicated in FIG. 1 by arrows of different lengths.
  • FIGS. 1 and 2 show the state in which a strip 2 is pushed one last step into the forming tool 1.
  • the foremost tooth 8 at the front end of the finger rod 3 is in the immediate vicinity of the forming tool, but without coming into conflict with the same.
  • the finger bar can be withdrawn before the working stroke of the forming tool, if this is necessary.
  • the position of a newly placed strip 2 can also be seen in FIG. Under this strip, the finger bar 3 is now pulled back by a relatively large stroke into the position according to FIG. 3, in which the rearmost finger 4 of the finger bar 3 engages just behind the rear edge of the strip 2.
  • the finger bar 3 with the strip 2 is then moved forward by a practically identical step, into the position according to FIG. 4.
  • FIG. 5 shows a further stage in which the strip 2 has already been partially processed and the finger rod 3 has been reset for the further gradual advancement of the strip 2 to such an extent that the finger 7 becomes effective in order to advance the strip further.
  • the finger rod 3 must be withdrawn again so that the finger 8 at the front end of the finger bar is used to advance the strip into the end position according to FIGS. 1 and 2.
  • any conditions can now be met, for example differently dimensioned feed steps, possibly also differently dimensioned feed strokes for strips of different lengths.
  • the strip guide can be moved transversely to the feed direction to process two or more rows of the strip.
  • FIG. 6 shows a possible complete movement cycle of the finger bar 3, the feed or feed positions of the finger bar being shown in solid lines, while the return positions are shown in dashed lines.
  • the respective positions of the rear edge 2 'of the strip 2 are shown under the finger bars 3.
  • FIG. 6 above shows the retracted starting position of the finger bar according to FIG. 3, in which the finger 4 detects the strip 2 in the position shown.
  • the next position, in which the fingers 4 - 8 are all still shown, corresponds to the first processing position according to FIG. 4, in which the strip has been advanced by the finger 4.
  • the finger bar is already pulled back into the position in which the finger 6, of which only the front edge is shown, detects the strip. There then follow three further positions in which the finger 6 advances the strip by one step each.
  • a toothed belt which is moved back and forth accordingly, could also be provided as funding. So far it has been assumed that there is a single grant, e.g. B. a single finger bar available. However, several funds, e.g. B. finger poles, arranged side by side, which are of the same design and are moved.
