Definitions

  • the present invention relates to a device for producing cutting templates, with a cutting table on which the sheet material from which the cutting templates are made, with a device for separating the cutting templates from the remaining part of the sheet material, this cutting device located above the Cutting table is located, and with a device for selectively holding the sheet material by negative pressure on the cutting table.
  • the aforementioned stencils can be used, for example, in the clothing, upholstery and shoe industries.
  • Cardboard, plastic, paper, metal foil or sheet metal etc. can be used as the template material. It is known that during the production of cutting templates, a sheet of one of the materials mentioned lies on the cutting table, from which the cutting templates are cut out.
  • the working surface of the cutting table is provided with air passages, the mouths of which lie below the flat stencil material.
  • the other ends of the said passages are connected to a device that can generate negative pressure.
  • negative pressure is first generated in the passages, with the result that the material sheet lies tightly on the flat surface of the cutting table. This ensures that the sheet is flat and that it cannot move on the working surface of the cutting table during the cutting process.
  • the negative pressure in the passages causes the An Number of air molecules between the sheet of material and the table surface, which allow the ß ⁇ gen slide on the table surface, is greatly reduced. As a result, both the entire sheet of material and individual parts of it adhere strongly to the table surface. At the point where the cutting tool of the cutting device has cut through the material sheet, air can penetrate under this material part again. The further penetration of air molecules under the parts of the stencil material that are more distant from the interface is relatively slow because of the strong adhesion of the flat material on the surface of the cutting table.
  • the cutting templates that have already been cut out of the material sheet continue to adhere to the table surface after the cutting process has ended.
  • the object of the present invention is to provide a device which does not have the disadvantages mentioned.
  • the device for producing cutting templates which is shown in the accompanying drawing, has a cutting table 1, on which there is the two-dimensional material 2 from which cutting templates are made. Above the table 1 there is a device 3 for separating those parts of the sheet material 2 from the rest of the same which represent the cutting templates.
  • Said separation device 3 contains a bridge 4, which is approximately U-shaped in a front view. Through the vertical legs of this bridge 4, of which only the front leg 5 of the bridge 4 can be seen in the drawing, horizontally lying guide rods 6 pass through, which are attached laterally to the cutting table 1 and which run parallel to the working surface of the cutting table 1.
  • the web 7 connecting the vertical legs 5 is located above the working surface of the table 1 and it extends to the longitudinal direction of the table 1.
  • a cutting device 8 can be moved along the web 7 mentioned.
  • This cutting device 8 contains a support part 9, which is in engagement with the bridge 7 and to which a cutting head 10 is attached so as to be vertically movable.
  • the cutting table 1 to ge wa part of the cutting head 10 is provided with a cutting tool 11.
  • This cutting tool 11 can be designed, for example, as a milling cutter, graver or knife, or it can act on the template material electroerosively, with an arc, etc.
  • the type of cutting tool 11 largely depends on the type of template material 2 used.
  • the cutting table 1 is further provided with a control device (not shown) which controls the movements of the bridge 4 on the guide rods 6 along the cutting table 1 and the cutting device 8 along the bridge 4 in accordance with the shape of the desired cutting template. Since such control devices for the production of cutting templates are generally known, a more detailed description of this control device is omitted here.
  • the present device also has a transport pad 15 which can be moved along the cutting table 1 and which lies directly on the surface of the cutting table 1 and on which the stencil material 2 rests in the region of the table surface.
  • this transport document 15 is a self-contained, i.e. Endless structure that wraps around the support surface of the cutting table 1.
  • the transport pad 15 is shown in the drawing with the aid of a dash-dotted line in order to be able to distinguish this pad 15 in the area of the working surface of the cutting table 1 from the other parts shown here.
  • the transport pad can be made of an airtight material, e.g. be made of cardboard, plastic, paper, metal foil, etc., such a transport pad (15) having continuous openings.
  • the transport pad can also be made of a textile material, e.g. from a fabric or from a nonwoven.
  • the cutting table 1 is provided with rollers 16, 17, 18 and 19, over which the transport pad 15 is guided. At least one of these rollers 16 to 19 can be driven by means of a drive device 20. which is only hinted at in the drawing.
  • a tensioning device 21 is also provided for the transport pad 15, which has a tensioning roller 22. This tension roller 22 is located above the lower left guide roller 18 for the transport pad 15. The chip roller 22 can be pressed against the outside of the transport pad 15 with the aid of a device, not shown, whereby the desired tension in the pad 15 can be achieved.
  • the transport pad mentioned is a web that is rewound from one end section of the cutting table 1 to the opposite end section thereof.
  • the one end part of the cutting table 1 is provided with a supply roller for the web-shaped transport pad.
  • the opposite end of the cutting table is then equipped with a roller for winding up the transport document.
  • the rollers just mentioned are driven by the drive device 20 for the transport pad 15.
  • the template material 2 already mentioned has the shape of a web in the example shown.
  • a supply roll 25 with the stencil material 2 that has not yet been processed.
  • the stencil material 2 is first guided to the surface of the cutting table 1, where it is on the Transport pad 15 rests and where it is processed using the cutting device.
  • a further roller 26 on which the rest of the already processed template material 2, ie the waste 27, is wound.
  • the take-up roller 26 contains a shaft 28, the ends of which each slide in a fork 29 and which can also be driven by means of the drive device 20 already mentioned. Since the take-up roller 26 is merely resting in the forks 29, it can be quickly removed from the device and on the steep side thereof, a shaft 28 which is still empty can be inserted into the device just lay
  • Two of the guide rollers 16 and 17 already mentioned for the transport pad 15 are located in the upper region of the cutting table 1 in such a way that the tangent to the respective guide rollers 16 and 17, respectively, which runs horizontally and touches the uppermost part of the guide rollers 16 and 17 mentioned, in the plane of the working surface of the cutting table 1 or a little below.
  • Such a position of the upper guide rollers 16 and 17 enables easy guidance of the transport pad 15 over the work surface of the table 1.
  • the other two guide rollers 18 and 19 for the transport pad are in the lower part of the cutting table 1 and they are used primarily for returning the Transport pad 15.
  • the tensioning roller 22 is connected upstream of the lower left guide roller 18.
  • This collecting device 30 contains an obliquely arranged plate 32 falling off the exit edge 31 of the cutting table 1, the lower edge part of this plate 32 being provided with a stop 33.
  • This stop 33 is approximately at right angles to the base plate 32 mentioned and it is relatively high so that several layers of Sehnitschabionen can rest on this stop 33.
  • the entire working surface of the cutting table 1 is provided with transverse air passages 34, of which only two such passages are shown in the drawing.
  • the upper mouth of the respective passage is located under the transport pad 15.
  • the passages 34 open into a collecting chamber 35, which is located under the working surface of the table 1 and which is connected via a line 36 is connected to a device 37 for generating negative pressure in the collecting chamber 35 and thus also in the passages 34.
  • the operation of the cutting device 3 is controlled according to the desired shape of the cutting templates. This is done in a known manner using a computer.
  • the front end of the web 2 made of the stencil material 2 is guided up to the shaft 28 for the winding roller 26, where this front end of the web 2 is fastened.
  • the greater part of the material web 2, which is located between the two rollers 25 and 26, rests on that section of the transport pad 15 which lies on the working surface of the cutting table 1.
  • the device 37 for generating negative pressure can now be put into operation, so that air is first extracted from the area below the transport pad 15. Since the base 15 is permeable to air, that air is also sucked out, which is between the stencil material 2 on the table 2 and the Tr an s po rtu nte r l a ge. The web 2 made of the template material now adheres firmly to the transport base 15 and thus also to the table 1. The cutting templates from the web material 2 can now be cut out.
  • the mode of operation of the separating device 3 is programmed in such a way that the separating device 3 can move as far as possible over the entire width and length of the cutting table 1 in order to cut out cutting templates from the template material 2. Here, as little waste as possible 27 should arise.
  • Vacuum device 37 turned off so that the atmospheric pressure can build up again between the flat material 2 on the table 1 and the table surface. Then the drive device 20 for the transport substrate 15 and for the winding roller 26 for the waste 27 is put into operation. The material web 2 and also the transport pad 15 now move in the direction towards the take-up roller 26, the waste 27 reaching this roller 26 freely suspended. In the area of the upper left guide roller 17, the transport pad 15 is sharply deflected downward, while the waste 27 moves approximately in the same direction as far as the winding roller 26. In this area of the present device, the cut-out cutting templates separate from the remaining part of the material web 2 and they fall into the collecting device 30 for the latter.
  • the drive device 2 for the transport pad 15 and the winding roller 26 is switched off and the vacuum device 37 can be switched on in order to produce a new set of cutting templates can.
  • a device for processing the waste 27 by cutting can be provided. This device can also be driven by the device 20 for driving the transport pad 15.
