Definitions

  • the present invention relates to a method and a Transfer arrangement on a press for gradual Transporting workpieces through a machining station Tool according to the preamble of claim 1 or 2.
  • a A method or an arrangement of this type is known from DE-A-33 20 830.
  • the transport rods lead pro Working cycle a closed rectangular movement, by recording a number in a first bar Advance workpieces to the next station of the tool, then laterally removed from the tool, lengthways returned and for gripping the workpieces back to Tools are moved.
  • Transfer movement is usually a vertical movement overlaid by the transport bars with the grippers slightly raised after each gripping of the workpieces so that the captured workpieces can be safely the next station of the tool. Without these Vertical movement there is a risk that workpieces during Running into a next station against parts of the same could strike. This additional vertical movement of the Transport bars and grabs bring a significant Price increases and an increase in the inert masses with it.
  • the aim of the present invention is to have a simple structure the transfer arrangement a safe transfer of the To ensure workpieces. That goal will in the generic method achieved that by means of the attached to the grippers Magnet the workpiece during transport from one Processing station to the next without vertical movement of the transport bars and grippers is raised. thanks this very simple measure is the disadvantageous Vertical movement of the transport bars and grippers away.
  • a Another advantage is that the grippers are rigid executed and rigidly connected to the transport rods could be. You only need to Orientation means, for example V-shaped End faces or orientation pins, which the workpieces during the lifting by the Magnets and during the transfer of workpieces from one Processing station in the next in the desired position to back up.
  • a transfer arrangement according to the invention is defined in claim 2. Preferred embodiments are given in dependent claims 3 to 7.
  • Figure 1 shows a section of the transfer system Press, with two transport bars 1, on which two rigid Grippers 2 and 3 are permanently installed. These grippers are used in the way described above for detecting and Transporting a workpiece 4, namely a deep-drawn part with a raised middle part 4a and an annular flange 4b.
  • the two grippers 2 and 3 have V-shaped ones End faces 5, which in the case of FIG shown, closed position lowest mutual distance between the two grippers 2 and 3 with something Play against the raised middle part 4a of the workpiece 4 and orient it in a certain position.
  • the two grippers are each with two permanent magnets 6 occupied, the lower end faces are flush with the Bottom of the grippers 2 and 3.
  • a sensor 7 for presence control mounted on a cable 8 with the press control connected is. It is assumed that the workpiece is behind completed processing in a processing station in a in Figure 2 indicated by dashed lines. To the The workpiece is captured and transported further Transport rods 1 with the grippers 2 and 3 from one spread position in the shown in Figures 1 and 2, closed or approximated position shifted. Here the grippers move, as shown in Figure 2, over the Flange 4b of the workpiece inwards and orient it Workpiece with its end faces 5 against lateral Shift. However, the orientation is done with a certain game, d. H. the workpiece can move between the Practically move the grippers freely in the vertical direction.
  • the magnets 6 lying over the flange 4b now lift that ferromagnetic workpiece in the in Figure 2 in solid lines shown raised position in which then the workpiece in the next processing station brought.
  • the sensor 7 monitors the Presence of a workpiece and in the absence of a Workpiece immediately stopping the press.
  • the illustrated embodiment shows the possibility how deep-drawn workpieces are oriented and raised can. Flatter workpieces cannot do this be oriented.
  • the grippers 2 and 3 be provided with orientation pins, either by rest against the edge of the workpiece or in Intervene in the orientation holes of the workpiece.
  • orientation pins 9 the orientation of the workpiece serve by abutting the flange 4b from the outside, are shown in Figure 1 in dash-dotted lines. It orientation pins could also be provided, which when lifting the workpiece by the magnets 6 in Penetrate the same orientation holes.
