Definitions

  • the invention relates to a device for producing wire baskets for securing bottle corks, in particular sparkling wine corks, according to the preamble of patent claim 1.
  • a method for producing such wire baskets in which the basket shape is produced from a wire star consisting of four individual wires while leaving a central opening free by twisting wire pairs and bending or rolling the ends of the wire pairs.
  • the twisting is accomplished in such a way that the twisted area is followed by an untwisted area, which is followed by a loop (crossing point C) and an end-side, again parallel formation, cf.
  • the German translation of EP-A-00 44 798 see in particular Fig. 3-6 and the associated description). This is to avoid jamming in automatic distributors.
  • a device suitable for this process is not described.
  • the invention is therefore based on the object of providing a device with the aid of which such wire baskets can be produced from preformed wire stars at high production speeds.
  • production speeds of up to over 100 pieces per minute are to be achieved in order to be able to integrate this device with correspondingly fast automatic machines into a production facility which first preform wire stars or, in a third stage following the present device, assemble wire rings on the wire basket finally twist the bottle neck around twisting.
  • Such a device which is fundamentally independent of the type of manufacture of the wire bracket and the type of final completion of the bottle cork securing device, is characterized by an extremely high production speed. This can be can be attributed to the fact that the individual steps of cutting, hook formation and kinking of the legs as well as the ejection or ejection process are so divided by the shape of the tool and the punches that these processes each take the same time and permit high cycle times.
  • the stamp and the ejector can be driven synchronously by a common cam, which also leads to a less complex construction.
  • the molds are identical to each other, only the stamps are designed differently and interact with different areas of the molds. Because the chain wheels lie one above the other in one plane and the chain is thus guided vertically in the lateral areas, the space requirement of the device according to the invention is also small.
  • the wire brackets can be fed in any way and held on the tools, for example by grippers.
  • the stirrups on these magnets remaining in the cutting and hook-shaping stage:
  • a separate holder is not required in the following stage, the cup formation, since the cone angle of the molding tool can be selected so that the cup can be held securely by the spring action of the legs resting on it.
  • Stops can be advantageously arranged behind the molding tools, on which the tools can be supported when the punches engage.
  • a rear rail is sufficient, through which the tools are guided by the chain.
  • the last stamp can be provided with a supply of prefabricated caps which, when the corks are secured, lie between them and the wire circle or the immediately adjacent area of the legs.
  • These caps consist of sheet metal which is cut to size and, if necessary, bulged, mostly printed, but which are primarily used only for optical purposes.
  • the molding tool with a central opening located above the inner cone, through which the ejector can act on the wire basket in order to eject the basket held by the clamping action.
  • the ejection device is designed in a divided manner and has a spring-loaded ejection pin which is held in the tool and which projects over the top edge of the tool in the rest position.
  • the ejector itself can be wider than the ejector pin, i.e. have a larger diameter than the pin. To eject it is therefore only necessary to press the ejector pin down to the level of the upper edge of the tool, so that there can be no malfunction due to inaccurate positioning and jamming of the ejector in the opening.
  • a particularly space-saving configuration which is suitable for the subsequent processing, if necessary, by inserting and securing a locking ring, is seen in the fact that the ejector lies between the sprockets lying vertically one above the other in a plane following a deflection from the horizontal tool guide.
  • Fig. 1 shows four pairs in a plane vertically one above the other sprockets 1,1 ', on which on a chain 2,2' molds 3 revolve gradually at the same distance from each other.
  • the molds 3 fill the chain completely, so that no empty steps are required.
  • the dies 3, 4, 4, 6 are arranged at a suitable point, which interact with corresponding instruments of the dies, but each die has all the instruments shown in FIGS. 4 and 5 are shown in more detail.
  • a previously supplied wire bracket 24 which has the shape of a star interwoven from four individual wires with a central circle and twisted legs protruding therefrom at angles of 90 °, is optionally to the required length tailored. If the stirrups are cut to length by other external tools, this step can of course be omitted. However, a cut at this point is preferred.
  • the second processing stage is used with the aid of the stamp 5 to produce end hooks 9 in the legs; the hooks 9 are intended for receiving a locking ring which is ultimately to be inserted.
  • the punch 5 has concave recesses 7 and the tool 3 has corresponding bulges 8.
  • the bracket 24 provided with hooks 9 is formed into a basket 25 which, after being guided around the sprocket 1 'deflected by 90 °, is removed by an ejector 15 from the tool 3.
  • Fig. 2 shows the mold 3 in cooperation with the punch 4, which is guided as a slide on a rail.
  • Four knives 18 are arranged on the side of the tool 3, which interact with the corresponding counter knives 23 on the stack 4 and cut off excess wire pieces.
  • the wire bracket 24 is held on the tool 3 by springs 16 provided with magnets.
  • the punch 4 is moved back and the tool 3 is moved over the next punch 5 and stopped there.
  • FIG. 3 shows this next processing stage, in which four hooks 9 are formed in the legs 28 of the cut-off bracket 24 by the raised punch 5.
  • the plunger 5 has four correspondingly concave recesses 7 and the tool 3 has convex bulges 8 positioned opposite one another.
  • the knives 18 not required in this stage are indicated on the tool 3.
  • the punch 5 is moved back and the tool, like all other tools, is moved one step further.
  • Fig. 4 shows the shape of the basket 25, on which the hooks 9 from the previous stage (Fig. 3) can be seen.
  • the tool 3 has a central inner cone 12, into which the wire circle 26 is pushed with the aid of the stamp 6 up to a contact surface 27, the legs 28 resting against the inner cone 12 and there after the stamp 6 has been moved back by clamping action or, if appropriate remain magnetically secured.
  • the wire bracket 24 is indicated in dashed lines in the initial form. For the sake of clarity, only two legs 28 of the basket 25 are shown, two more are perpendicular to it.
  • On the stamp 6 is a sheet metal cap 31 before the formation of the basket 25, which is pressed into the wire circle 26 and the roots of the legs 28 and remains there.
  • the ejector 15 After the formation of the wire basket 25, this is moved around the lower sprocket 1 'by 90 ° into a vertical position over the required number of steps and the ejector 15 is positioned opposite.
  • the ejector 15 has an end face 29 which acts on an ejector pin 21. In the rest position, this pin 21 is pressed away from the basket 25 by a spring 20 and projects beyond the upper die card 19. Its length is such that the end face 29 of the ejector 15 does not have to penetrate into the guide 30 for the pin 21 to eject the basket 25, so that certain positioning inaccuracies can be compensated for.
  • wire rings can be inserted into the hooks 9, which serve to finally close the fuse by twisting it around a bottle neck.
  • the wire baskets can be stored temporarily or also fed directly to the further processing.
