Definitions

  • the present invention relates to a method for feeding and advancing a strip into and through a Forming tool according to the preamble of claim 1, and a strip feeder for performing this procedure.
  • Processes and strip feeders of this type are e.g. B. from DE-U-8,220,431 (closest state of the art) or EP-A-0,409,151.
  • a rotating conveyor that is a belt or a roller, and these conveying elements must if they are provided with a driving finger, after the gradually advance a strip the full way run back to capture another streak.
  • Conveyor rollers provided, it is hardly possible in all Cases to move strips or the like parts accurately, and the rear end of the same sufficiently close to one Convey tool.
  • US-A-4,090,703 shows an apparatus for feeding and Feeding strips into and through a Forming tool with three different conveyor units from which the finger sticks with in uniform Spaced fingers to gradually advance of a strip.
  • the funding bodies are with driven by a uniform, non-adjustable stroke.
  • the aim of the present invention is to Avoid functional disadvantages with a simple structure. This goal is according to claim 1 or 3 reached. Since the finger bar in the longitudinal direction or Direction of movement has several fingers, preferably are at different distances from each other extensive freedom in programming and it are always limited, quickly executable steps of, for example, a maximum of 400 mm is required.
  • FIG. 1 shows a forming tool 1, for example for punching out of rondelles from strips 2.
  • the strips 2 point the usual form with wavy sides on which with optimal use of the material according to FIG. 2 e.g. B. two rows of offset in the longitudinal and transverse directions Rondelles can be punched out. But of course it can another processing, for example a deformation of the material.
  • the strip feeder has one Finger rod 3, which in the embodiment with five resilient fingers or carriers 4-8 is occupied. These fingers are spring loaded when unloaded over the finger bar 3 in front, and can thus one Grip strip 2 on its rear edge and take it with you, and the fingers covered by a strip are placed in the Finger rod 3 pushed in.
  • the three in the conveying direction rearmost fingers 4 - 6 are in a smaller mutual Distance than the front fingers 6, 7 and 8.
  • the foremost Finger 8 lies at the front end of finger bar 3 and can thus a strip 2 according to FIG. 2 in the last Position for cutting out the last roundel or for editing insert the last part into a strip, without colliding with the forming tool.
  • the Remaining grid of the strip from which all parts are punched out are, by means of a pair of pull-out rollers 9 from the Forming tool removed.
  • the strips 2 are made from one Magazine 10 by means of a vertical stacker 11 in a known Taken individually and in a manner not shown On the guideway, on which they pass through the fingers of the Finger bar 3 detected and fed to the forming tool 1 can be.
  • the finger bar 3 is programmable Linear drive 12 connected, the whole program perform any forward and return strokes can, as indicated in Fig. 1 by arrows of different lengths is.
  • FIGS. 1 and 2 show the state, in which a strip 2 by one last step is advanced into the forming tool 1.
  • the foremost Tooth 8 at the front end of the finger bar 3 is in immediate vicinity of the forming tool without, however, with the same to come into conflict. Even before the working stroke of the The finger bar can be withdrawn, if necessary. 2 is already the Position of a newly placed strip 2 can be seen. Under this strip is now the finger bar 3 by one relatively large stroke retracted into the position according to FIG. 3, in which the rearmost finger 4 of the finger bar 3 grips just behind the rear edge of the strip 2. The Finger bar 3 with the strip 2 is then practical same step forward, into position according to FIG. 4.
  • the strip 2 thus comes in as far the forming tool 1 that the first machining is done can.
  • the finger bar 3 is again in the immediate range Near the forming tool 1 has been advanced and must now again to advance the strip 2 again be withdrawn.
  • the next finger 5, or the next but one finger 6 are used to move the Advance stripes gradually.
  • Figure 5 shows a further stage in which the strip 2 is already at Part is processed and the finger bar 3 for further incremental advancement of the strip 2 so far has been that the finger 7 is effective to the To advance strips further.
  • the finger bar 3 must be pulled back again so that the finger 8 at the front end of the finger bar for use comes to the strip to the end position according to the figures To advance 1 and 2.
  • the finger bar and thanks to its programmable Drive can now meet any conditions different feed steps, for example if necessary also different sized Feed strokes for strips of different lengths.
  • the stripe guide can be moved across the feed direction if necessary to process two or more rows of the strip.
  • Figure 6 shows a possible complete movement cycle the finger bar 3, the feed or feed positions the finger bar are shown in full lines, while the return positions are shown in dashed lines are.
  • the respective positions are under the finger bars 3 the rear edge 2 'of the strip 2 shown.
  • Fig. 6 above is the retracted starting position of the Finger rod shown in FIG. 3, in which the finger 4 captured the strip 2 in the position shown.
  • the next position, in which fingers 4 - 8 are still all are shown corresponds to the first processing position 4, in which the strip through the finger 4 has been advanced.
  • the finger bar is already pulled back into the position in which the finger 6, of which only the front edge is shown, the Stripes captured.
