Lesdits outils de formage (3) sont dotés d'arrêtes tranchantes (18), de saillies (8) et d'un cône intérieur (12). Ils peuvent être dirigés progressivement vers trois poinçons (4, 5, 6), dont le premier (4) comporte, par exemple, des couteaux (23), le second (5), des indentations (7), qui coopèrent avec les saillies (8) de l'outil de formage (3) de manière à former des crochets (9) à l'extrémité des branches (28), et le troisième (6), une surface de pression, qui presse la partie centrale (26) de l'arceau de fil métallique (24) dans le cône (12), formant ainsi le muselet (25). Un éjecteur (15) est ajouté dans une étape ultérieure.Said device is in particular intended for bottles of sparkling wine. It consists of prefabricated wire hoops (24) comprising four sections of wire, which are arranged in a circle from which four small twisted branches protrude horizontally. A chain (2, 2 '), to which forming tools (3) are attached, passes through four chain wheels (1, 1') arranged in pairs, perpendicular to each other. Said forming tools (3) are provided with cutting edges (18), protrusions (8) and an inner cone (12). They can be directed progressively towards three punches (4, 5, 6), of which the first (4) comprises, for example, knives (23), the second (5), indentations (7), which cooperate with the projections (8) of the forming tool (3) so as to form hooks (9) at the end of the branches (28), and the third (6), a pressure surface, which presses the central part (26) ) of the wire arch (24) in the cone (12), thus forming the muzzle (25). An ejector (15) is added in a later step.

Description

Vorrichtung zur Herstellung von Drahtkörbchen zur Sicherung von FlaschenkorkenDevice for the production of wire baskets for securing bottle corks
Die Erfindung betrifft eine Vorrichtung zur Herstellung von Draht körbchen zur Sicherung von Flaschenkorken, insbesondere von Schaumweinkorken, gemäß dem Oberbegriff des Patentanspruchs 1.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.
Bekannt ist ein Verfahren zur Herstellung derartiger Drahtkörb¬ chen, bei welchem aus einem aus vier Einzeldrähten bestehenden Drahtstern unter Freilassung einer zentralen Öffnung durch Ver¬ drillen von Drahtpaaren sowie Umbiegen oder Einrollen der Draht¬ paarenden die Körbchenform hergestellt wird. Dabei wird das Verdrillen so bewerkstelligt, daß an den ver¬ drillten Bereich ein unverdrillter anschließt, dem eine Um¬ schlingung (Kreuzungspunkt C) und eine endseitige wieder parallele Ausformung folgt, vgl. die deutsche Übersetzung der EP-PS 00 44 798 (vgl. insbesondere Fig. 3-6 und die zugehörige Beschreibung). Hierdurch soll ein Verhaken in automatischen Ver¬ teilern vermieden werden. Eine für diesen Vorgang geeignete Vor¬ richtung ist nicht beschrieben.A process for producing wire baskets of this type is known, 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.
Der Erfindung liegt von daher die Aufgabe zugrunde, eine Vorrich¬ tung zu schaffen, mit deren Hilfe derartige Drahtkörbchen aus vorgeformten Drahtsternen mit hoher Produktionsgeschwindigkeit gefertigt werden können. Insbesondere sollen Produktionsge¬ schwindigkeiten von bis zu über 100 Stück pro Minute erreicht werden, um diese Vorrichtung mit entsprechend schnellen Automaten zu einer Fertigungseinrichtung integrieren zu können, die zunächst Drahtsterne vorformen bzw. in einer an die vorliegende Vorrichtung anschließenden dritten Stufe an den Drahtkörbchen Drahtringe mon¬ tieren, die letztlich unter Verdrillen den Flaschenhals um¬ schlingen. Die Lösung dieser Aufgabe gelingt bei einer Vorrichtung zur Her¬ stellung von Drahtkörbchen gemäß dem Oberbegriff des Anspruchs 1 durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1.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. In particular, 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.
Ausgestaltungen im Rahmen der Erfindung ergeben sich aus den Unteransprüchen 2 bis 7.Refinements within the scope of the invention result from subclaims 2 to 7.
Eine solche Vorrichtung, die grundsätzlich unabhängig ist von der Art der Herstellung der Drahtbügel und der Art der letztlichen Fertigstellung der Flaschenkorken-Sicherung, zeichnet sich durch eine extrem hohe Produktionsgeschwindigkeit aus. Dies läßt sich u.a. darauf zurückführen, daß die einzelnen Schritte Schneiden, Hakenformung und Abknicken der Beinchen sowie der Ausstoß- bzw. Auswerfvorgang derart durch die Werkzeuggestalt und die Stempel aufgeteilt sind, daß diese Vorgänge jeweils die gleiche Zeit in Anspruch nehmen und hohe Taktzeiten erlauben. Somit lassen sich auch die Stempel sowie der Auswerfer von einer gemeinsamen Kurven scheibe synchron antreiben, was auch zu einer wenig aufwendigen Konstruktion führt.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. Thus, the stamp and the ejector can be driven synchronously by a common cam disc, which also leads to a less complex construction.
Die Formwerkzeuge sind dabei untereinander gleich, lediglich die Stempel sind unterschiedlich gestaltet und wirken mit unterschied lichen Bereichen der Formwerkzeuge zusammen. Dadurch, daß die Kettenräder in einer Ebene übereinanderliegen und die Kette in de seitlichen Bereichen somit vertikal geführt ist, ist auch der Platzbedarf der erfindungsgemäßen Vorrichtung gering.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.
Die Drahtbügel können in beliebiger Weise zugeführt und an den Werkzeugen z.B. durch Greifer gehalten werden. Es hat sich jedoch für die FunktionsSicherheit als förderlich erwiesen, in Ausge¬ staltung der Erfindung die Bügel mit Hilfe gefederter Magnete zu halten, wobei die Bügel an diesen Magneten in der Stufe Schneiden und Hakenformung verbleiben. Eine eigene Halterung ist in der folgenden Stufe, der Kör chenformung, nicht erforderlich, da der Konuswinkel des Formwerkzeuges so gewählt werden kann, daß das Körbchen durch die Federwirkung der an diesem anliegenden Beinche sicher gehalten werden kann. Hinter den Formwerkzeugen können vorteilhafterweise Anschläge angeordnet sein, an denen sich die Werkzeuge beim Eingriff der Stempel abstützen können. Im einfachsten Falle genügt dazu eine rückwärtige Schiene, über die die Werkzeuge von der Kette geführt werden.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.
Gewünschtenfalls kann der letzte Stempel mit einer Zuführung von vorgefertigten Kappen versehen sein, die beim Sichern der Korken zwischen diesen und dem Drahtkreis bzw. dem unmittelbar an¬ schließenden Bereich der Beinchen liegen. Diese Kappen bestehen aus rund zugeschnittenen und gegebenenfalls vorgewölbten meist bedruckten Blechen, die jedoch vornehmlich nur optischen Zwecken dienen.If desired, 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.
Weiterhin wird vorgeschlagen, das Formwerkzeug mit einem zentralen, über dem Innenkonus liegenden Durchbruch auszustatten, durch den hindurch der Auswerfer auf das Drahtkörbchen einwirken kann, um das durch Klemmwirkung gehaltene Körbchen auszuwerfen. I besonders vorteilhafter Weise ist die Auswerfeinrichtung jedoch geteilt ausgebildet und weist einen gefederten, im Werkzeug ge¬ haltenen Auswerfstift auf, der in Ruhelage die Werkzeugoberkante überrag .Furthermore, it 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. In a particularly advantageous manner, however, 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.
Der Auswerfer selbst kann dabei breiter sein als der Auswerfstift d.h. einen größeren Durchmesser als der Stift aufweisen. Zum Aus¬ werfen ist es somit lediglich erforderlich, den Auswerfstift bis maximal auf das Niveau der Werkzeugoberkante niederzudrücken, so daß es nicht zu einer Fehlfunktion durch ungenaues Positionieren und Verklemmen des Auswerfers im Durchbruch kommen kann.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.
Eine besonders platzsparende und für die gegebenenfalls sofort anschließende Weiterverarbeitung durch Einlegen und Sichern eines Verschlußringes geeigneter Ausgestaltung wird darin gesehen, daß der Auswerfer zwischen den in einer Ebene senkrecht übereinander liegenden Kettenrädern im Anschluß an eine Umlenkung aus der horizontalen Werkzeugführung liegt. Anhand der schematischen Zeichnung wird die Erfindung beispielhaft näher erläutert.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. 1 zeigt vier paarweise in einer Ebene vertikal übereinander angeordnete Kettenräder 1,1', an denen auf einer Kette 2,2' Form¬ werkzeuge 3 in gleichem Abstand voneinander schrittweise umlaufen. Dabei füllen die Formwerkzeuge 3 die Kette vollständig aus, so daß keine Leerschritte erforderlich sind. Im Bereich des unteren Kettentrums 2 - sind an geeigneter Stelle den Formwerkzeugen 3 gegenüberliegend Stempel 4,5,6 angeordnet, die mit entsprechenden Instrumenten der Formwerkzeuge zusammenwirken, wobei aber jedes Formwerkzeug vollständig über alle Instrumente verfügt, die in den Fig. 2,3,4 und 5 näher dargestellt sind.1 shows 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. In the area of the lower chain center 2, 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.
In der ersten Bearbeitungsstufe wird mit Hilfe von am Stempel 4 angeordneten Gegen essern 23 ein vorher zugestellter Draht¬ bügel 24, der die Form eines aus vier Einzeldrähten verflochtenen Sternes mit einem mittleren Kreis und davon unter Winkeln von 90° abstehenden verdrillten Beinchen hat, gegebenenfalls auf die erforderliche Länge zugeschnitten. Werden die Bügel vorher von anderen externen Werkzeugen abgelängt, kann diese Stufe natürlich grundsätzlich entfallen. Ein Zuschnitt an dieser Stelle wird jedoch vorgezogen. Die zweite Bearbeitungsstufe dient mit Hilfe des Stempels 5 zur Herstellung von endseitigen Haken 9 in den Beinchen; die Haken 9 sind zur Aufnahme eines letztlich einzulegenden Verschlußringes bestimmt. Dazu weist der Stempel 5 konkave Ausnehmungen 7 und das Werkzeug 3 entsprechende Ausbuchtungen 8 auf.In the first processing stage, with the aid of counter-eaters 23 arranged on the punch 4, 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. For this purpose, the punch 5 has concave recesses 7 and the tool 3 has corresponding bulges 8.
Mit Hilfe des Stempels 6 wird der mit Haken 9 versehene Bügel 24 zu einem Körbchen 25 geformt, das nach Führung um das Kettenrad 1' um 90° umgelenkt durch einen Auswerfer 15 aus dem Werkzeug 3 ent¬ fernt wird.With the aid of the stamp 6, 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.
Das Umlenken vor dem Auswerfen bringt eine erhebliche Platzein¬ sparung mit sich.The deflection before the ejection brings about a considerable saving in space.
Fig. 2 zeigt das Formwerkzeug 3 im Zusammenwirken mit dem Stem¬ pel 4, der als Schlitten auf einer Schiene 22 geführt ist. Seitlich am Werkzeug 3 sind vier Messer 18 angeordnet, die mit den entsprechenden Gegenmessern 23 am Stapel 4 zusammenwirken und überstehende Drahtstücke abschneiden. Der Drahtbügel 24 ist am Werkzeug 3 von mit Federn 16 versehenen Magneten 17 gehalten.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.
Nach dem Abschneiden der Drahtüberlängen wird der Stempel 4 zurückgefahren und das Werkzeug 3 über den nächsten Stempel 5 bewegt und dort angehalten.After the wire excess lengths have been cut off, the punch 4 is moved back and the tool 3 is moved over the next punch 5 and stopped there.
Fig. 3 zeigt diese nächste Bearbeitungsstufe, in der durch den hochgefahrenen Stempel 5 vier Haken 9 in die Beinchen 28 des abge¬ längten Bügels 24 geformt werden. Dazu weist der Stempel 5 vier entsprechend liegende konkave Ausnehmungen 7 und das Werkzeug 3 gegenüber positionierte konvexe Ausbuchtungen 8 auf. Die in dieser Stufe nicht erforderlichen Messer 18 sind am Werkzeug 3 ange¬ deutet. Der Stempel 5 wird nach Formung der vier Haken 9 zurück¬ gefahren und das Werkzeug, wie alle anderen Werkzeuge ebenfalls, um einen Schritt weiterbewegt. Fig. 4 zeigt die Formung des Körbchens 25, an dem die Haken 9 aus der vorherigen Stufe (Fig. 3) erkennbar sind. Dazu weist das Werk¬ zeug 3 einen zentralen Innenkonus 12 auf, in den mit Hilfe des Stempels 6 der Drahtkreis 26 bis zu einer Anlagefläche 27 gescho¬ ben wird, wobei sich die Beinchen 28 an den Innenkonus 12 anlegen und dort nach Zurückfahren des Stempels 6 durch Klemmwirkung oder gegebenenfalls zusätzlich magnetisch gesichert verbleiben. Strichliert ist der Drahtbügel 24 in der Ausgangsform angedeutet. Der Übersichtlichkeit halber sind lediglich zwei Beinchen 28 des Körbchens 25 dargestellt, zwei weitere stehen senkrecht dazu. Auf dem Stempel 6 liegt vor der Formung des Körbchens 25 eine Blech¬ kappe 31, die in den Drahtkreis 26 und die Ansätze der Beinchen 28 eingepreßt wird und dort verbleibt.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. For this purpose, 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. After the four hooks 9 have been formed, 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. For this purpose, 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. On the stamp 6, before the basket 25 is formed, there is a sheet metal cap 31 which is pressed into the wire circle 26 and the roots of the legs 28 and remains there.
Nach der Formung des Drahtkörbchens 25 wird dieses um das untere Kettenrad 1' um 90° herum in eine senkrechte Stellung über die dazu erforderliche Anzahl von Schritten bewegt und dem Aus¬ werfer 15 gegenüber positioniert. Der Auswerfer 15 besitzt gemäß Fig. 5 eine Stirnfläche 29, die auf einen Auswerferstift 21 ein¬ wirkt. Dieser Stift 21 ist in Ruheposition durch eine Feder 20 vom Körbchen 25 weggedrückt und steht über die Formwerkzeugober¬ kante 19 vor. Seine Länge ist so bemessen, daß die Stirnfläche 29 des Auswerfers 15 zum Ausstoßen des Körbchens 25 nicht in die Füh¬ rung 30 für den Stift 21 eindringen muß, so daß gewisse Positio- nierungsungenauigkeiten ausgeglichen werden können.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. According to FIG. 5, 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.
Über das obere Kettenrad 1' werden die Werkzeuge 3 im Kreislauf zurückgeführt.The tools 3 are returned in the circuit via the upper sprocket 1 '.
Nach dem Auswerfen des Drahtkörbchens 25 können in die Haken 9 Drahtringe eingelegt werden, die zum endgültigen Verschließen der Sicherung durch Verdrillen um einen Flaschenhals dienen. Dazu können die Drahtkörbchen zwischengelagert oder auch direkt zur Weiterverarbeitung zugeführt werden. 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. For this purpose, the wire baskets can be stored temporarily or can be fed directly for further processing.
