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 claim 1.
• a process for producing wire baskets of this type in which the basket shape is produced from a wire star consisting of four individual wires, 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 (intersection point C) and an end-side again parallel formation, cf.
• the German translation of EP-PS 00 44 798 see in particular Fig. 3-6 and the associated description. This is to prevent jamming in automatic distributors.
• a device suitable for this process is not described.
• the invention is therefore based on the object of creating 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 device which first preform wire stars or, in a third stage following the present device, wire rings mon ⁇ animals that ultimately twist around the bottle neck while twisting.
• This object is achieved in a device for producing wire baskets according to the preamble of claim 1 by the features in the characterizing part of patent claim 1.
• 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 disc, 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. Characterized in that the sprockets 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. However, it has proven to be beneficial for the functional reliability to hold the stirrups with the aid of spring-loaded magnets in the embodiment of the invention, the stirrups on these magnets remaining in the cutting and hook-forming stage.
• a separate bracket is not necessary in the following stage, the chen chenformung, since the cone angle of the mold can be chosen so that the basket can be held securely by the spring action of the adjacent legs. Stops can advantageously be arranged behind the molding tools, on which the tools can be supported when the punches engage. In the simplest case, 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 is proposed to equip 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, in the rest position, projects above the upper edge of the tool.
• 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 push 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 chain wheels lying vertically one above the other in a plane following a deflection from the horizontal tool guide.
• the invention is explained in more detail by way of example with reference to the schematic drawing.
• Fig. 5 shows the ejection mechanism
• FIGS. 4 and 5 show four chain wheels 1, 1 'arranged vertically one above the other in pairs on one plane, on which forming tools 3 revolve step by step on a chain 2, 2'.
• the molds 3 completely fill the chain, so that no empty steps are required.
• punches 4, 5, 6 are arranged at a suitable point opposite the forming tools 3, which interact with corresponding instruments of the forming tools, but each forming tool has all the instruments shown in FIGS. 4 and 5 are shown in more detail.
• a wire bracket 24 which has been previously provided and 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 opened cut the required length. If the stirrups are cut to length by other external tools beforehand, this step can of course basically 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 chain wheel 1 ', is deflected by 90 ° by an ejector 15 from the tool 3.
• FIG. 2 shows the molding tool 3 in cooperation with the stamp 4, which is guided as a slide on a rail 22.
• 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 any excess wire pieces.
• the wire bracket 24 is held on the tool 3 by magnets 17 provided with springs 16.
• 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 elongated bracket 24 by the raised punch 5.
• the punch 5 has four correspondingly concave recesses 7 and the tool 3 has convex bulges 8 positioned opposite one another.
• the knives 18 which are 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 step (Fig. 3) can be seen.
• the tool 3 has a central inner cone 12, into which the wire circle 26 is pushed up to a contact surface 27 with the aid of the stamp 6, the legs 28 resting against the inner cone 12 and there after the stamp 6 has been moved back remain magnetically secured by clamping action or, if necessary, additionally.
• 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, and two more are perpendicular to it.
• the wire basket 25 After the wire basket 25 has been formed, it is moved around the lower sprocket 1 ′ through 90 ° into a vertical position over the number of steps required for this purpose and positioned opposite the ejector 15.
• 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 cup 25 by a spring 20 and projects beyond the upper edge 19 of the mold. Its length is such that the end face 29 of the ejector 15 does not have to penetrate the guide 30 for the pin 21 to eject the basket 25, so that certain positioning inaccuracies can be compensated for.
• the tools 3 are returned in the circuit via the upper sprocket 1 '.
• the wire basket 25 After the wire basket 25 has been ejected, 9 wire rings can be inserted into the hooks, which serve to finally close the securing device by twisting it around a bottle neck.
• the wire baskets can be stored temporarily or can be fed directly for further processing.
