Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Spulenwechsel und insbesondere zum Wechseln einer mit metallischem Stranggut gefüllten vollen Spule gegen eine leere Spule in einer Verlitzmaschine.The present invention relates to a device for changing bobbins and in particular for changing a full bobbin filled with metallic strand material for an empty bobbin in a bunching machine.

Mit der DE 35 00 949 C2 ist eine automatisch arbeitende Spulenwechselvorrichtung für eine Doppelschlagverlitzmaschine bekannt geworden. Bei dieser bekannten Vorrichtung ist eine Verlegerolle vorgesehen, die die fertiggestellte Litze an einer Aufwickelspule entlangführt, um eine gleichmäßige Verlegung des Wickelgutes zu gewährleisten. Sobald der vorbestimmte Füllungsgrad der Spule erreicht ist, wird der Fertigungsvorgang und das Aufspulen der Litze auf die Spule so lange fortgesetzt, bis die Verlegerolle eine vorbestimmte Position am Seitenflansch der Spule erreicht hat. Anschließend wird die Spule von einem Hubtisch aufgenommen und aus ihrer horizontalen Lage in der Maschine abgesenkt, wobei die Spule aber weiterhin mit der in der Maschine befindlichen Litze verbunden ist. Um einen übermäßigen Zug in der Litze zu vermeiden, wird die Spule beim Absenken rückwärts gedreht. Nach dem Absenken der Spule wird die Litze mit einer Halte- und Schneideinrichtung durchtrennt und das zur Maschine laufende Ende der Litze festgehalten. Die auf dem Hubtisch befindliche Spule wird dann durch ein Schwenkgestell ergriffen und aus der Maschine herausgeschwenkt.From DE 35 00 949 C2, an automatically operating bobbin changing device for a double-twist bunching machine has become known. In this known device, a laying roller is provided, which guides the finished strand along a winding spool in order to ensure a uniform laying of the winding material. As soon as the predetermined degree of filling of the bobbin is reached, the manufacturing process and the winding of the strand onto the bobbin continue until the laying roller has reached a predetermined position on the side flange of the bobbin. The coil is then picked up by a lifting table and lowered from its horizontal position in the machine, but the coil is still connected to the stranded wire located in the machine. In order to avoid excessive tension in the strand, the bobbin is turned backwards when it is lowered. After lowering the The bobbin is cut with a holding and cutting device and the end of the strand running towards the machine is held in place. The spool on the lifting table is then gripped by a swivel frame and swung out of the machine.

Obwohl diese Vorrichtung zufriedenstellend arbeitet, hat sich doch gezeigt, daß sie die heutigen, erhöhten Ansprüche an die Genauigkeit der Produktionslängen einerseits und an den Automatisierungsgrad andererseits nicht zu erfüllen vermag. So ist es ein grundsätzlicher Nachteil der bekannten Vorrichtung, daß die Verlegebewegung immer so lange fortgesetzt werden muß, bis sich die Verlegerolle in einer bestimmten Endlage im Bereich des dazu vorbestimmten Spulenflansches befindet. Im ungünstigsten Fall müssen also nach dem Erreichen der gewünschten Meterzahl auf der Spule noch fast zwei weitere Wickellagen aufgebracht werden, bis sich die Verlegerolle in der Endlage befindet, in der ein Spulenwechsel möglich ist. Aufgrund der Abmessungen derartiger Rollen kann dies bedeuten, daß mehrere hundert Meter Litze zusätzlich auf die Rolle aufgewickelt werden müssen.Although this device works satisfactorily, it has been shown that it cannot meet today's increased demands on the accuracy of the production lengths on the one hand and on the degree of automation on the other. It is a fundamental disadvantage of the known device that the laying movement must always be continued until the laying roller is in a specific end position in the region of the coil flange predetermined for this. In the worst case, after the desired number of meters has been reached, almost two additional winding layers must be applied to the reel until the laying roller is in the end position in which a bobbin change is possible. Due to the dimensions of such rolls, this can mean that several hundred meters of strand must also be wound onto the roll.

Dies bedeutet zum einen einen wirtschaftlichen Verlust für den Drahthersteller, wichtiger ist jedoch die Tatsache, daß die auf der Spule befindliche Überlänge die weitere Drahtherstellung erheblich beeinträchtigen kann. Dies ist z.B. dann der Fall, wenn aus mehreren dünnen Litzen eine dickere Litze hergestellt werden soll. Da die dickere Litze nur so lang sein kann, wie die kürzeste auf den Zuführspulen befindliche Litze, kann die auf den einzelnen Spulen befindliche Überlänge nicht verwendet werden, sondern muß manuell von den Spulen entfernt werden. Die Kabelhersteller legen deshalb großen Wert darauf, daß alle bewickelten Spulen exakt die gleiche Kabellänge aufweisen.On the one hand, this means an economic loss for the wire manufacturer, but more important is the fact that the excess length on the spool can significantly impair the further wire production. This is the case, for example, if a thicker strand is to be produced from several thin strands. Since the thicker strand can only be as long as the shortest strand on the feed spools, the excess length on the individual spools cannot be used, but must be manually removed from the spools. Cable manufacturers therefore attach great importance to ensuring that all wound coils have exactly the same cable length.

Ein weiteres Problem bei derartigen Wechselvorrichtungen ist die Bereitstellung eines ausreichend langen, nach außen geführten inneren Endes der Litze. Die Litzen werden in der Regel nach ihrer Fertigstellung in einem kontinuierlichen Prozeß mit Kunststoff ummantelt. Um diesen Prozeß nicht zu unterbrechen, muß das innere Ende derjenigen Spule, von welcher der Draht gerade abgezogen wird, mit dem äußeren Ende der nachfolgenden Spule verschweißt oder verlötet werden. Dazu muß das aus der fertigen Spule herausgeführte innere Ende eine gewisse Länge aufweisen, die bei der bekannten Vorrichtung jedoch sehr begrenzt ist. Weiterhin ist es nicht möglich, den Automatisierungsgrad der bekannten Vorrichtung mit angemessenem Aufwand zu erhöhen.Another problem with such changing devices is the provision of a sufficiently long, inner end of the strand leading outwards. The strands are usually covered with plastic in a continuous process after their completion. In order not to interrupt this process, the inner end of the coil from which the wire is being drawn off must be welded or soldered to the outer end of the subsequent coil. For this purpose, the inner end led out of the finished coil must have a certain length, which, however, is very limited in the known device. Furthermore, it is not possible to increase the degree of automation of the known device with reasonable effort.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Wechseln einer gefüllten Spule gegen eine leere Spule in einer Spuleinrichtung und insbesondere in der Spuleinrichtung einer Doppelschlagverlitzmaschine zu schaffen, welche bzw. welches das Wechseln der Spule ermöglicht, sobald die vorbestimmte Menge von strangförmigem Gut auf die Spule aufgewickelt ist, welches in kurzer Zeit durchgeführt werden kann, und welches es ermöglicht, ein langes inneres Ende des Stranggutes für die Weiterverarbeitung zur Verfügung zu stellen und den Spulenwechselvorgang vollständig zu automatisieren.The present invention is therefore based on the object of providing a method and a device for changing a filled bobbin against an empty bobbin in a winding device and in particular in the winding device of a double-twist bunching machine, which enables the bobbin to be changed as soon as the predetermined amount of strand-like material is wound onto the spool, which can be carried out in a short time, and which makes it possible to provide a long inner end of the strand material for further processing and to fully automate the spool changing process.

Durch die Erfindung wird es ermöglicht, den Spulenwechsel auszuführen, sobald die vorbestimmte Menge des Stranggutes auf die Spule aufgewickelt ist. Sobald diese vorbestimmte Menge erreicht ist, wird die Spule stillgesetzt. In diesem Zustand befindet sich die Verlegeeinrichtung, die sich parallel zur Spulenachse bewegt, in einer beliebigen Position in bezug auf die Innenflansche der Spule. Nach dem Stillsetzen der Spule wird eine Stranggut-Greifeinrichtung von einer ersten Position, die sich in einem Abstand zur Spule befindet, in eine zweite Position in die Nähe der Spule, und zwar in den Bereich zwischen der Spule und der Verlegeeinrichtung gebracht. Während dieses Vorganges befindet sich die Greifeinrichtung vorzugsweise in einer Position in der Nähe eines der beiden Innenflansche der Spule. Anschließend wird die Greifeinrichtung parallel zur Spulenlängsachse bewegt, bis sie in Kontakt mit dem Stranggut kommt, welches sich zwischen der stillstehenden Spule und der stillstehenden Verlegeeinrichtung befindet. Die Greifeinrichtung ergreift das Stranggut und bewegt sich von der Spule weg, und zwar vorzugsweise in ihre erste Position zurück, wobei dies allerdings in einer Ebene senkrecht zur Spulenlängsachse erfolgt, die der Ebene entspricht, in der sich die Verlegerolle zum Zeitpunkt des Stillsetzens der Spuleinrichtung befindet. Während des Zurückfahrens der Greifeinrichtung wird die Spule entgegen ihrer üblichen Drehrichtung zum Aufspulen des Stranggutes gedreht, so daß ein Teil des Stranggutes wieder abgewickelt wird. Dadurch bildet sich zwischen der gefüllten Spule, der Greifeinrichtung und der Verlegeeinrichtung eine Stranggutschleife.The invention makes it possible to carry out the bobbin change as soon as the predetermined amount of the strand material has been wound onto the bobbin. As soon as this predetermined amount is reached, the coil is stopped. In this state, the laying device, which moves parallel to the coil axis, is in any position with respect to the inner flanges of the coil. After the spool has stopped, an extrudate gripping device is brought from a first position, which is at a distance from the spool, to a second position in the vicinity of the spool, specifically in the area between the spool and the laying device. During this process, the gripping device is preferably in a position in the vicinity of one of the two inner flanges of the coil. The gripping device is then moved parallel to the longitudinal axis of the coil until it comes into contact with the stranded material which is located between the stationary coil and the stationary laying device. The gripping device grips the strand material and moves away from the spool, preferably back to its first position, although this takes place in a plane perpendicular to the longitudinal axis of the spool, which corresponds to the plane in which the laying roller is at the time the winding device is stopped . During the retraction of the gripping device, the spool is rotated counter to its usual direction of rotation for winding up the strand material, so that part of the strand material is unwound again. As a result, an extrudate loop is formed between the filled bobbin, the gripping device and the laying device.

Anschließend wird das Stranggut in der Nähe der gefüllten Spule mit einer Schneideinrichtung geschnitten und mit einer Halteeinrichtung festgehalten, so daß die Stranggutschleife nun zwischen der Verlegerolle und dieser Halteeinrichtung besteht.The extrudate near the filled bobbin is then cut with a cutting device and with held by a holding device, so that the strand loop now exists between the laying roller and this holding device.

Die gefüllte Spule kann nun durch eine Handhabungseinrichtung aus der Spuleinrichtung entnommen und eine leere Spule eingesetzt werden.The filled spool can now be removed from the spooling device by a handling device and an empty spool can be inserted.

Nach dem Einsetzen der Leerspule wird das Ende des Stranggutes, das in der Halteeinrichtung gehalten ist, in eine Klemmeinrichtung im Bereich des Außenflansches der Leerspule festgeklemmt und mit der Greifeinrichtung in den Spulenwickelraum zwischen den beiden Spuleninnenflanschen gelegt. Danach kann das Aufspulen auf die Leerspule erfolgen.After inserting the empty spool, the end of the stranded goods, which is held in the holding device, is clamped in a clamping device in the area of the outer flange of the empty spool and placed with the gripping device in the coil winding space between the two inner spool flanges. Then the winding onto the empty spool can take place.

Der gesamte Wechselvorgang wird durch eine Steuereinrichtung gesteuert und überwacht.The entire changing process is controlled and monitored by a control device.

Die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren erlauben es, eine genau definierte Stranggutlänge auf die Spule aufzuwickeln, da die Spule unmittelbar nach Erreichen der vorbestimmten Länge gestoppt wird und der Spulenwechsel aus jeder Stellung der Verlegeeinrichtung heraus erfolgen kann. Da die Position des strangförmigen Gutes während des Spulenwechsels durch die Greifeinrichtung einerseits und die Halteeinrichtung andererseits sehr genau definiert ist, kann das Einbringen des Stranggutes in die Klemmeinrichtung mit hoher Zuverlässigkeit erfolgen, wodurch Betriebsstörungen vermieden werden. Dieses ist sehr wichtig, da derartige Anlagen, insbesondere während der Nachtschichten, ohne Bedienungspersonal arbeiten können sollen.The device according to the invention and the method according to the invention allow a precisely defined length of extruded material to be wound onto the spool, since the spool is stopped immediately after the predetermined length has been reached and the spool can be changed from any position of the laying device. Since the position of the strand-like material during the bobbin change is very precisely defined by the gripping device on the one hand and the holding device on the other hand, the strand material can be introduced into the clamping device with a high degree of reliability, thereby avoiding malfunctions. This is very important since such systems should be able to work without operating personnel, especially during the night shifts.

Die Zuverlässigkeit wird weiter erhöht, wenn die Klemmeinrichtung, gemäß einer bevorzugten Weiterbildung der Erfindung, durch eine über die Steuereinrichtung steuerbare Betätigungseinrichtung betätigt wird. Damit wird eine Fehlfunktion der Klemmeinrichtung, wie z.B. ein versehentliches Öffnen vor dem Wiederanlaufen der Spuleinrichtung, vermieden.The reliability is further increased if the clamping device, According to a preferred development of the invention, it is actuated by an actuating device which can be controlled via the control device. This prevents a malfunction of the clamping device, such as an accidental opening before restarting the winding device.

Ein weiterer Vorteil der Vorrichtung ist es, daß die einzelne Bauelemente an vorhandene Maschinen, insbesondere Doppelschlagverlitzmaschinen, nachgerüstet werden können.Another advantage of the device is that the individual components can be retrofitted to existing machines, in particular double twist bunching machines.

Gemäß einer weiteren bevorzugten Ausführungsform ist eine Abklebeeinrichtung vorgesehen, durch welche sowohl das äußere Ende des Stranggutes als auch, nach einem Überwerfen des inneren Endes des Stranggutes auf die Wicklungen, das innere Ende festgeklebt werden kann. Das Festkleben kann mit Klebeband oder Etiketten erfolgen, so daß der Spulenwechselvorgang mit allen Einzelvorgängen vollständig automatisiert ist. Das Abkleben erfolgt vorzugsweise im eingespannten Zustand der Spule, so daß deren Drehantrieb für das Abkleben genutzt werden kann.According to a further preferred embodiment, a masking device is provided, by means of which both the outer end of the strand material and, after the inner end of the strand material has been thrown onto the windings, the inner end can be glued. The sticking can be done with adhesive tape or labels so that the bobbin changing process is fully automated with all individual processes. The masking is preferably done in the clamped state of the coil, so that its rotary drive can be used for masking.

Wenn die Spule in der Spuleinrichtung, was zu bevorzugen ist, mit horizontaler Achse gehalten ist, erfolgt das Ausbringen der gefüllten Spule aus der Spuleinrichtung vorzugsweise mit einem Hubtisch, welcher in eine Position unterhalb der gefüllten Spule gebracht und anschließend angehoben wird, um die Spule aufzunehmen. Sobald die Spule in entsprechender Weise auf dem Hubtisch aufliegt, wird die Spanneinrichtung der Spule gelöst und die Spule mit dem Hubtisch abgesenkt. Der Hubtisch ist vorzugsweise um eine vertikale Achse schwenkbar, so daß die Spule durch eine Drehung um einen vorgegebenen Winkel, unter Beibehaltung ihrer horizontalen Lage, aus der jeweiligen Spuleinrichtung bzw. der Maschine ausgebracht werden kann. Bei einem vollständig automatisierten System wird die volle Spule dann durch eine Greifeinrichtung aufgenommen und durch eine leere Spule ersetzt, die dann wieder mittels des Hubtisches in eine Position vertikal unterhalb der Wickelposition geschwenkt und in die Spannposition gehoben wird. Im Unterschied zum Stand der Technik kann der Hubtisch wesentlich einfacher ausgeführt werden, da die Spule während des Absenkens nicht drehbar gelagert werden muß.If the bobbin is held with a horizontal axis in the bobbin, which is preferred, the filled bobbin is preferably brought out of the bobbin with a lifting table, which is brought into a position below the filled bobbin and then raised to accommodate the bobbin . As soon as the coil rests on the lifting table in a corresponding manner, the tensioning device of the coil is released and the coil with the lifting table is lowered. The lifting table is preferably pivotable about a vertical axis, so that the spool can be removed from the respective winding device or the machine by rotating through a predetermined angle while maintaining its horizontal position. At In a fully automated system, the full bobbin is then picked up by a gripping device and replaced by an empty bobbin, which is then pivoted back into a position vertically below the winding position by means of the lifting table and lifted into the tensioning position. In contrast to the prior art, the lifting table can be made much simpler, since the coil does not have to be rotatably supported during the lowering.

Nach dem Festspannen der Spule wird das durch die Handhabungseinrichtung gehaltene innere Ende dann in die Klemmeinrichtung eingelegt.After the coil has been tightened, the inner end held by the handling device is then inserted into the clamping device.

Die Klemmeinrichtung ist vorzugsweise an einer Scheibe befestigt, die parallel zu einem Außenflansch der Spule angeordnet ist, und welche einen umlaufenden Ringvorsprung aufweist, auf den ein Teil des Stranggutes aufgewickelt wird. Dazu wird die Spule in der entsprechenden Wickelrichtung gedreht und die Greifeinrichtung gleichzeitig auf die Spule zubewegt, so daß ein Teil dieser gebildeten Drahtschleife auf diesen Ringvorsprung aufgespult wird. Anschließend kann dann die Greifeinrichtung derart verfahren werden, daß das Stranggutende von der Position außerhalb des Wickelraumes in eine Position innerhalb des Wickelraumes zwischen den Innenflanschen der Spule überführt wird. Sobald diese Position erreicht ist, wird die Greifeinrichtung in einer solchen Weise parallel zur Spulenlängsachse der Leerspule bewegt, daß sich das Stranggut von der Greifeinrichtung löst und die Greifeinrichtung in ihre erste Warteposition zurückgefahren werden kann.The clamping device is preferably attached to a disc which is arranged parallel to an outer flange of the coil and which has a circumferential annular projection on which a part of the strand material is wound. For this purpose, the spool is rotated in the corresponding winding direction and the gripping device is simultaneously moved towards the spool, so that part of the wire loop formed is wound onto this ring projection. The gripping device can then be moved in such a way that the end of the strand material is transferred from the position outside the winding space to a position within the winding space between the inner flanges of the coil. As soon as this position has been reached, the gripping device is moved parallel to the longitudinal axis of the empty spool in such a way that the strand material detaches from the gripping device and the gripping device can be moved back into its first waiting position.

Während die Hubeinrichtung vorzugsweise unmittelbar an der Spuleinrichtung, also z.B. an der Doppelschlagverlitzmaschine befestigt ist, sind die übrigen Bestandteile der Spulenwechselvorrichtung, d.h. insbesondere die Greifeinrichtung, die Halte- und Schneideinrichtung, die Klebeeinrichtung usw., zu einer Manipulationseinrichtung zusammengefaßt, die vorzugsweise in bezug auf die Spuleinrichtung verfahrbar ist. Dadurch ist es möglich, mit einer einzelnen Spulenwechselvorrichtung bzw. Manipulationseinrichtung, den Spulenwechsel an einer Vielzahl von entsprechend gestalteten Spuleinrichtungen durchzuführen. Dies bedeutet eine wesentliche Reduzierung der Investitionskosten für die Spulenwechselvorrichtung.While the lifting device is preferably attached directly to the winding device, for example to the double-twist bunching machine, the remaining components of the bobbin changing device, ie in particular the gripping device, are the holding and cutting device, the gluing device, etc., combined to form a manipulation device which can preferably be moved with respect to the winding device. This makes it possible to use a single bobbin changing device or manipulation device to change the bobbin on a large number of appropriately designed bobbins. This means a substantial reduction in the investment costs for the bobbin changing device.

Fig. 1 zeigt in einer schematischen Darstellung eine Vorderansicht einer Doppelschlagverlitzmaschine mit einer Spulenwechselvorrichtung gemäß der Erfindung.Fig. 1 shows a schematic representation of a front view of a double-twist beating machine with a bobbin changing device according to the invention.

Der insgesamt mit 1 bezeichneten Doppelschlagverlitzmaschine wird (von links in der Darstellung in Fig. 1) ein Drahtbündel 2 zugeführt, welches in der Doppelschlagverlitzmaschine zu einer Litze geformt wird. Die Doppelschlagverlitzmaschine weist dazu, wie im Stand der Technik bekannt, ein oder zwei Bügel 3 auf, welche durch eine (in Fig. 1 nicht sichtbare) Antriebseinrichtung, im üblichen Fall ein Elektromotor, in Drehung versetzt werden. Die Drehachse liegt dabei in der Zeichenebene der Fig. 1.A wire bundle 2 is fed to the double-twist bunching machine, designated overall by 1 (from the left in the illustration in FIG. 1), which is formed into a strand in the double-bunching beating machine. For this purpose, as known in the prior art, the double-twist bunching machine has one or two brackets 3, which are set in rotation by a drive device (not visible in FIG. 1), in the usual case an electric motor. The axis of rotation lies in the plane of the drawing in FIG. 1.

Eine Wickelspule 5, deren Längsachse 6 in der Darstellung gemäß Fig. 1 senkrecht zur Zeichenebene ist, ist in der Doppelschlagverlitzmaschine angeordnet, um die fertiggestellte Litze aufzuspulen. Die Spule rotiert mit den Bügeln 3 und um ihre Längsachse, um die Litze aufzuwickeln.A winding spool 5, the longitudinal axis 6 of which in the illustration according to FIG. 1 is perpendicular to the plane of the drawing, is arranged in the double-twist bunching machine in order to wind up the finished strand. The spool rotates with the brackets 3 and about its longitudinal axis in order to wind up the strand.

Die Vorrichtung wird insgesamt durch eine Steuereinrichtung 8 gesteuert, die schematisch in Form eines Schaltschrankes neben der Doppelschlagverlitzmaschine dargestellt ist. Ein Portalgerüst 10 ist vorgesehen, an dem eine Spulentransportvorrichtung 11, sowie die nun in bezug auf die Fig. 2 und 3 beschriebene Manipulationseinrichtung 9 verfahrbar befestigt ist.Overall, the device is controlled by a control device 8, which is shown schematically in the form of a control cabinet next to the double-twist bunching machine. A portal frame 10 is provided, on which a coil transport device 11 and the manipulation device 9 now described with reference to FIGS. 2 and 3 are movably attached.

Die Manipulationseinrichtung 9 ist, wie insbesondere in Fig. 3 zu erkennen ist, mittels eines vertikalen Stützträgers 12 an einem Querträger 13 des Portalgerüstes befestigt. Parallel zum vertikalen Stützträger 12 ist eine Spindel 14 angeordnet, welche durch eine (nicht dargestellte) Antriebseinrichtung gedreht werden kann. Auf der Spindel ist eine Spindelmutter 16 befestigt, die eine Hubbewegung nach oben oder nach unten ausführt, wenn die Spindel 14 gedreht wird.As can be seen in particular in FIG. 3, the manipulation device 9 is fastened to a cross member 13 of the portal frame by means of a vertical support beam 12. A spindle 14 is arranged parallel to the vertical support beam 12 and can be rotated by a drive device (not shown). A spindle nut 16 is attached to the spindle, which has a lifting movement executes up or down when the spindle 14 is rotated.

Die Spindelmutter 16 ist ihrerseits über eine Tragplatte 17 mit einem, sich ebenfalls im wesentlichen in vertikaler Richtung erstreckenden Tragrahmen 19 verbunden.The spindle nut 16 is in turn connected via a support plate 17 to a support frame 19 which also extends essentially in the vertical direction.

An diesem vertikalen Tragrahmen 19 und in einem spitzen Winkel 21, der vorzugsweise etwa 45° beträgt, ist ein weiterer Tragrahmen 22 befestigt, der die ausfahrbare Stranggut-Greifeinrichtung 24 aufnimmt, die nachfolgend kurz als Greifeinrichtung bezeichnet wird.On this vertical support frame 19 and at an acute angle 21, which is preferably approximately 45 °, a further support frame 22 is attached, which receives the extendable extrudate gripping device 24, hereinafter referred to as a gripping device.

Die Greifeinrichtung 24 weist eine Stange 26 auf, welche verschieblich in bezug auf den Tragrahmen 22 gelagert ist.The gripping device 24 has a rod 26 which is slidably mounted with respect to the support frame 22.

Am unteren Ende der Stange 26 ist ein Winkel 28 vorgesehen, welcher zwei nach vorne vorspringende Platten 30a, 30b aufweist, die elektrisch gegeneinander isoliert sind. Die Platten 30a und 30b sind jeweils mit der Steuereinrichtung 8 verbunden.At the lower end of the rod 26 there is an angle 28, which has two protruding plates 30a, 30b which are electrically insulated from one another. The plates 30a and 30b are each connected to the control device 8.

Im unteren Bereich des Winkels 28 ist eine drehbare Rolle 32 befestigt, in welche sich das strangförmige Gut einhängt.In the lower region of the angle 28, a rotatable roller 32 is fastened, in which the strand-like material hangs.

Die Verschiebung der Stange 26 erfolgt mittels eines pneumatischen Zylinders 33, der parallel zur Stange 26 angeordnet ist, und in dem ein Kolben längsbeweglich gelagert ist. Im Unterschied zu herkömmlichen Kolben-Zylinder-Anordnungen ist der Kolben jedoch nicht mit einer Kolbenstange verbunden, sondern mit einem Seilzug 35, der am Kolben befestigt ist und über Rollen 36, 37, die am Tragrahmen 22 gehalten sind, geführt ist. Der Seilzug 35 ist fest mit einer Hülse 38 verbunden, die ihrerseits über einen Winkel 39 an der Stange befestigt ist. Die Hülse 38 ist außerdem mit einem Ring 40 verbunden, der gleitbeweglich an dem Außenumfang des Zylinders 33 geführt ist.The rod 26 is displaced by means of a pneumatic cylinder 33 which is arranged parallel to the rod 26 and in which a piston is mounted so as to be longitudinally movable. In contrast to conventional piston-cylinder arrangements, however, the piston is not connected to a piston rod, but rather to a cable 35 which is fastened to the piston and is guided via rollers 36, 37 which are held on the support frame 22. The cable 35 is firmly connected to a sleeve 38, which in turn over an angle 39 is attached to the rod. The sleeve 38 is also connected to a ring 40 which is slidably guided on the outer circumference of the cylinder 33.

Durch diese Gestaltung ist es möglich, die Stange 26 mit vergleichsweise geringem Aufwand über eine große Strecke zu verschieben. Außerdem wird durch die Verwendung des Seilzuges eine lange Kolbenstange eingespart, die die Gesamtlänge der Vorrichtung wesentlich erhöhen würde.This design makes it possible to move the rod 26 over a long distance with comparatively little effort. In addition, the use of the cable saves a long piston rod, which would significantly increase the overall length of the device.

Ein besonderer Vorteil dieser Bauweise ist die exakt einstellbare Verschiebekraft. Bei den Funktionen, bei denen ein Zurückfahren der Greifeinrichtung erforderlich ist, wird der Druck im Zylinder 33 und damit die Kraft eingestellt, daß sie durch den von der Spule aufgebrachten Litzenzug kompensiert oder überwunden werden kann, ohne daß die Litze reißt.A particular advantage of this design is the precisely adjustable displacement force. In the functions in which a retraction of the gripping device is required, the pressure in the cylinder 33 and thus the force is set so that it can be compensated for or overcome by the strand pull applied by the spool without the strand breaking.

Statt der vorbeschriebenen Bauweise ist es auch möglich, die Stange 26 auf andere Art und Weise in Längsrichtung zu verschieben. So kann z.B. die Stange 26 als sogenannte Rund-Zahnstange ausgeführt werden, und dann über einen Elektromotor oder einen sonstigen Antrieb bewegt werden, der über ein Ritzel in die Verzahnung der Rund-Zahnstange eingreift.Instead of the construction described above, it is also possible to move the rod 26 in the longitudinal direction in another way. For example, the rod 26 are designed as a so-called round rack, and are then moved by an electric motor or another drive which engages with a toothing in the toothing of the round rack.

Ebenfalls am vertikalen Tragrahmen 19 ist in einem spitzen Winkel 41, der vorzugsweise 60° beträgt, ein weiterer Tragrahmen 42 angeordnet. Am unteren Ende des Tragrahmens 42 ist eine Halte- und Schneideinrichtung 43 vorgesehen, deren Aufbau im Stand der Technik bekannt ist. Die Betätigung der Halte- und Schneideinrichtung erfolgt über einen Pneumatikzylinder, dessen Zuführungen 44 in Fig. 3 schematisch mit eingezeichnet sind.Another support frame 42 is also arranged on the vertical support frame 19 at an acute angle 41, which is preferably 60 °. At the lower end of the support frame 42, a holding and cutting device 43 is provided, the structure of which is known in the prior art. The holding and cutting device is actuated via a pneumatic cylinder, the feeds 44 of which are shown schematically in FIG. 3.

Die Schneid- und Halteeinrichtung 43 ist in bezug auf den Tragrahmen 42 beweglich, d.h. sie kann in Richtung des Pfeiles 45 in Fig. 3, d.h. parallel zum Tragrahmen 42, ausgefahren und eingefahren werden, wobei der Antrieb über einen Pneumatikzylinder erfolgt.The cutting and holding device 43 is movable with respect to the support frame 42, i.e. it can be viewed in the direction of arrow 45 in Fig. 3, i.e. parallel to the support frame 42, extended and retracted, the drive being carried out via a pneumatic cylinder.

Am Tragrahmen 19 ist ferner über ein Traggestell 50 eine Platte 51 befestigt, auf der eine Betätigungseinrichtung 53 angeordnet ist. Die Betätigungseinrichtung 53 weist einen pneumatischen Zylinder auf, in dem ein Stößel 55 in Richtung des Doppelpfeiles 56 beweglich angeordnet ist. Die pneumatischen Zuführungen zur Betätigungseinrichtung 53 sind durch Stutzen 58 angedeutet.A plate 51, on which an actuating device 53 is arranged, is also fastened to the support frame 19 via a support frame 50. The actuating device 53 has a pneumatic cylinder in which a plunger 55 is arranged to be movable in the direction of the double arrow 56. The pneumatic feeds to the actuating device 53 are indicated by connecting pieces 58.

Die Tragplatte 51 nimmt weiterhin die Überwerfeinrichtung 60 auf, welche ebenfalls einen pneumatischen Zylinder aufweist, der einen beweglichen Stößel 61 aufnimmt. Der Stößel 61 ist in Richtung des Doppelpfeiles 62 bewegbar. Die pneumatischen Anschlußstutzen sind mit dem Bezugszeichen 63 gekennzeichnet.The support plate 51 also receives the throwing device 60, which also has a pneumatic cylinder which receives a movable plunger 61. The plunger 61 can be moved in the direction of the double arrow 62. The pneumatic connecting pieces are identified by reference number 63.

Am vorderen, vom pneumatischen Zylinder abgewandten Ende des Stößels 61 ist mittels eines Winkels 64 ein Überwerfstift 65 befestigt.A coupling pin 65 is attached to the front end of the plunger 61 facing away from the pneumatic cylinder by means of an angle 64.

Am vertikalen Tragrahmen 19 ist weiterhin mittels Zwischenträgern 70, 71 ein als Pneumatikzylinder gestalteter vertikaler Führungszylinder 72 befestigt, durch welche eine Abklebeeinrichtung 74 geführt ist.A vertical guide cylinder 72, designed as a pneumatic cylinder, is also attached to the vertical support frame 19 by means of intermediate supports 70, 71, through which a masking device 74 is guided.

Die Führung der Abklebeeinrichtung 74 erfolgt über eine Zylinderhülse 76, die längsverschieblich an dem Führungszylinder 72 angeordnet ist. Die Zylinderhülse 76 ist dazu über eine Befestigungseinrichtung 78 mit einem Seilzug 79 verbunden, der zu einem (nicht dargestellten) Kolben in dem Führungszylinder 72 geführt ist. Der Antrieb der Zylinderhülse 76 erfolgt also in gleicher Weise wie der Antrieb der Stange 26.The masking device 74 is guided via a cylinder sleeve 76 which is arranged on the guide cylinder 72 so as to be longitudinally displaceable. For this purpose, the cylinder sleeve 76 is connected via a fastening device 78 to a cable 79 which leads to a piston (not shown) in FIG the guide cylinder 72 is guided. The cylinder sleeve 76 is thus driven in the same way as the rod 26 is driven.

An der Zylinderhülse 76 ist ein horizontaler Tragrahmen 84 befestigt, an dem die Abklebeeinrichtung 74 drehbeweglich angeordnet ist, wobei die Drehachse 86 vertikal verläuft. Die Drehbewegung wird durch einen horizontal liegenden pneumatischen Drehzylinder 87 bewirkt, der eine Drehung der Abklebeeinrichtung zwischen zwei festgelegten Drehpunkten um einen Winkel von 180° ermöglicht.A horizontal support frame 84 is attached to the cylinder sleeve 76, on which the masking device 74 is rotatably arranged, the axis of rotation 86 extending vertically. The rotary movement is effected by a horizontally lying pneumatic rotary cylinder 87, which enables the masking device to be rotated between two fixed pivot points by an angle of 180 °.

Die Abklebeeinrichtung weist eine erste Rolle 90 auf, über welche ein mit Etiketten beklebtes Band 91 geführt ist. Eine Rolle 92 dient als Andruckrolle für die von der Rolle 90 abgenommenen Etiketten. Zum Abnehmen der Etiketten ist ein Blech 94 vorgesehen, über welches das Etikettenband 91 geführt ist. Die Breite der Abklebeeinrichtung und der Rollen 90, 92 ist so bemessen, daß das Band auch unmittelbar am Spulenflansch anliegend auf das Litzenende geklebt werden kann.The masking device has a first roller 90, over which a tape 91 stuck with labels is guided. A roller 92 serves as a pressure roller for the labels removed from the roller 90. To remove the labels, a plate 94 is provided, over which the label tape 91 is guided. The width of the masking device and the rollers 90, 92 is dimensioned such that the tape can also be glued to the end of the strand lying directly against the spool flange.

Das Entnehmen der gefüllten Spule aus der Doppelschlagverlitzmaschine erfolgt mit einer Hubeinrichtung, wie schematisch in den Fig. 4 und 5 dargestellt ist. Die insgesamt mit 100 bezeichnete Hubeinrichtung weist eine vertikale Tragsäule 101 auf, an der ein Führungszylinder 104 durch eine (nicht dargestellte) Antriebseinrichtung, vorzugsweise eine Kolben-Zylinder-Einheit, in Richtung des Doppelpfeiles 105 nach oben und nach unten bewegt werden kann.The filled bobbin is removed from the double-impact beating machine with a lifting device, as is shown schematically in FIGS. 4 and 5. The lifting device, designated as a whole by 100, has a vertical support column 101, on which a guide cylinder 104 can be moved up and down in the direction of the double arrow 105 by a drive device (not shown), preferably a piston-cylinder unit.

Dazu ist der Führungszylinder 104 über einen horizontalen Tragarm 106 mit einer Tragplatte 107 verbunden. Auf der Tragplatte 107 befinden sich zwei parallel zueinander angeordnete horizontale Stützbleche 109, 110, auf welchen die, in Fig. 4 schematisch angedeutete, Spule während des Entnehmens aufliegt.For this purpose, the guide cylinder 104 is connected to a support plate 107 via a horizontal support arm 106. On the support plate 107 there are two horizontal support plates 109, 110 arranged parallel to one another, on which the coil, indicated schematically in FIG. 4, rests during removal.

Eine weitere Antriebseinrichtung ist vorgesehen, um den Arm 106 und die Platte 107 um die senkrechte Tragsäule 101 in Richtung des Pfeiles 112 zu schwenken. Der Schwenkwinkel beträgt vorzugsweise 90°, so daß eine auf der Hubeinrichtung befindliche Spule, deren Längsachse parallel zu den Tragblechen 109, 110 ist, von einer Stellung, in der sie vertikal in bezug auf die Zeichenebene gemäß Fig. 1 steht, in eine Ebene geschwenkt wird, in der die Längsachse parallel zur Zeichenebene gemäß Fig. 1 ist.A further drive device is provided in order to pivot the arm 106 and the plate 107 around the vertical support column 101 in the direction of the arrow 112. The pivot angle is preferably 90 °, so that a coil located on the lifting device, the longitudinal axis of which is parallel to the support plates 109, 110, is pivoted from one position into which it is vertical with respect to the plane of the drawing according to FIG. 1 in which the longitudinal axis is parallel to the plane of the drawing according to FIG. 1.

Die Funktion der Hubeinrichtung wird, wie auch die übrige Funktion der Doppelschlagverlitzmaschine durch die Steuereinrichtung 8 gesteuert.The function of the lifting device, like the rest of the function of the double-twist bunching machine, is controlled by the control device 8.

Die vorstehend beschriebene Manipulationseinrichtung 9 ist dafür vorgesehen, an einer Vielzahl von Doppelschlagverlitzmaschinen, die in einer Reihe zueinander angeordnet sind, verwendet zu werden. Um die optimale Steuerung der einzelnen Maschinen und der Manipulationseinrichtung sicherzustellen, ist jede Doppelschlagverlitzmaschine mit einer Steuereinrichtung 8 verbunden. Zusätzlich ist eine übergeordnete (nicht dargestellte) Zentralsteuereinrichtung vorgesehen, die z.B. die Fahrbewegung des Portalgerüstes 10 und die Bewegung der Transporteinrichtung 11 steuert. Um eine optimale Funktion der Doppelschlagverlitzmaschinen und der Spulenwechselvorrichtung sicherzustellen, sind die Steuereinrichtung 8 und die Zentralsteuereinrichtung so beschaffen, daß die Steuerung der Spulenwechselvorrichtung durch die Steuereinrichtung 8 übernommen wird, sobald das Portalgerüst 10 sich an der entsprechenden Stelle befindet. Dazu ist eine elektro-mechanische oder aber auch eine logische Umschalteinrichtung vorgesehen, die bewirkt, daß die Steuereinrichtung 8 die Steuerung des Portalgerüstes 10 und der Manipulationseinrichtung 9 übernimmt, sobald der Spulenwechsel dort auszuführen ist.The manipulation device 9 described above is intended to be used on a large number of double-impact bunching machines which are arranged in a row with respect to one another. In order to ensure optimal control of the individual machines and the manipulation device, each double-impact bunching machine is connected to a control device 8. In addition, a superordinate (not shown) central control device is provided which controls, for example, the travel movement of the portal frame 10 and the movement of the transport device 11. In order to ensure optimal functioning of the double-twist bunching machines and the bobbin changing device, the control device 8 and the central control device are designed such that the control of the bobbin changing device is taken over by the control device 8 as soon as the gantry frame 10 is in the appropriate place. For this purpose, an electro-mechanical or a logical switching device is provided, which causes the control device 8 to take control of the portal frame 10 and the manipulation device 9 as soon as the bobbin change is to be carried out there.

Die Funktion des Ausführungsbeispiels gemäß den Fig. 1 bis 5 wird nun in bezug auf die Fig. 6 bis 8 weiter erläutert. Dabei wird zur besseren Verdeutlichung, vor der Spule 5 die zur Spuleneinrichtung gehörende Mitnehmerscheibe 128 mit dargestellt, die im wesentlichen den gleichen Durchmesser aufweist, wie die Flansche der Spule 5.The function of the exemplary embodiment according to FIGS. 1 to 5 will now be explained further with reference to FIGS. 6 to 8. For the sake of clarity, the driving disk 128 belonging to the coil device is also shown in front of the coil 5 and has essentially the same diameter as the flanges of the coil 5.

Die Doppelschlagverlitzmaschine 1 weist eine Sensoreinrichtung, vorzugsweise einen Meterzähler auf, der ein Signal an die Steuereinrichtung 8 ausgibt, sobald die vorbestimmte Litzenlänge auf der Spule 5 erreicht ist. Daraufhin wird die Doppelschlagverlitzmaschine sofort definiert stillgesetzt, was bedeutet, daß die Rotorbügel horizontal ausgerichtet sind und daß die Verlegung und die Spule in der jeweils eingenommenen Position fixiert werden. Die horizontale Fixierung erfolgt durch (nicht dargestellte) pneumatisch betätigte Indexbolzen.The double lay beating machine 1 has a sensor device, preferably a meter counter, which outputs a signal to the control device 8 as soon as the predetermined strand length on the spool 5 is reached. Thereupon, the double-twist bunching machine is immediately stopped in a defined manner, which means that the rotor brackets are aligned horizontally and that the laying and the spool are fixed in the respectively assumed position. The horizontal fixation is carried out by pneumatically operated index bolts (not shown).

Anschließend wird zunächst das lange innere Litzenende für die nächste Spule gebildet. Dazu wird die Manipulationseinrichtung 9 mit dem Portalgerüst 10 an die Doppelschlagverlitzmaschine 1 angekoppelt und die Steuerung der Manipulationseinrichtung durch die Steuereinrichtung 8 übernommen. Die Stranggut-Greifeinrichtung 24 wird, wie es in Fig. 6 dargestellt ist, so weit ausgefahren, daß sie sich in einer Position zwischen der Verlegeeinrichtung 120 und der Wickelspule 5 befindet. Dann wird das Portalgerüst 10 senkrecht zur Zeichenebene in Fig. 1 bewegt, wodurch die Greifeinrichtung 24 sich parallel zu der horizontal angeordneten Spulenachse 6 bewegt. Diese Bewegung wird solange fortgesetzt, bis die gefertigte Litze in Kontakt mit den Platten 30a und 30b an der Greifeinrichtung 24 kommt. Dadurch werden die elektrisch gegeneinander isolierten Platten elektrisch miteinander verbunden, und die Steuereinrichtung 8 stoppt die Bewegung des Portalgerüstes 10. Nun wird die Greifeinrichtung 24 mit einem Gegendruck beaufschlagt, der sie mit definierter Kraft in die Richtung zur ersten Position drückt, wodurch die drehbare Rolle 32 in Kontakt mit der in Fig. 6 mit L bezeichneten Litze kommt.Then the long inner strand end is formed for the next coil. For this purpose, the manipulation device 9 with the portal frame 10 is coupled to the double impact bunching machine 1 and the control device 8 controls the manipulation device. The strand gripping device 24, as shown in FIG. 6, is extended so far that it is in a position between the laying device 120 and the winding spool 5. The portal frame 10 is then moved perpendicular to the plane of the drawing in FIG. 1, as a result of which the gripping device 24 moves parallel to the horizontally arranged coil axis 6. This movement continues until the manufactured strand comes into contact with the Plates 30a and 30b on the gripping device 24 comes. As a result, the plates, which are electrically insulated from one another, are electrically connected to one another, and the control device 8 stops the movement of the portal frame 10. Now the gripping device 24 is subjected to a counterpressure which presses it in the direction of the first position with a defined force, as a result of which the rotatable roller 32 comes into contact with the strand designated L in FIG. 6.

Nun wird die Spule 5 in Richtung des Pfeiles 122 gedreht, d.h. entgegengesetzt zur normalen Spulrichtung, um die erforderliche Litzenlänge freizugeben. Die Drehung erfolgt über die Antriebseinrichtung der Doppelschlagverlitzmaschine.Now the coil 5 is rotated in the direction of arrow 122, i.e. opposite to the normal winding direction to release the required strand length. The rotation takes place via the drive device of the double-twist bunching machine.

Die Greifeinrichtung 24 fährt dabei vollständig zurück und befindet sich dann wieder in der Position, die in Fig. 6 mit festen Linien eingezeichnet ist. Die Litze bildet dann eine Schleife, welche aus den Litzensträngen La und Lb besteht. Nun wird die Halte- und Schneideinrichtung 43, die sich in einer Ebene, senkrecht zur Spulenlängsachse 6 mit der Greifeinrichtung 24 befindet, auf die Spule 5 zubewegt, und in eine Endposition gebracht, die in Fig. 6 dargestellt ist. In dieser Position wird die Litze durchgeschnitten und festgehalten, wodurch der Litzenstrang Lc entsteht. Die zwischen der Verlegeeinrichtung 120, der Greifeinrichtung 24 und der Halteeinrichtung 43 gebildete Litzenschleife besteht also nur noch aus den Litzensträngen La und Lc.The gripping device 24 moves back completely and is then again in the position which is shown in FIG. 6 with solid lines. The strand then forms a loop, which consists of the strand strands La and Lb. Now the holding and cutting device 43, which is located in a plane perpendicular to the coil longitudinal axis 6 with the gripping device 24, is moved towards the coil 5 and brought into an end position, which is shown in FIG. 6. In this position, the strand is cut through and held, whereby the strand Lc is created. The strand loop formed between the laying device 120, the gripping device 24 and the holding device 43 thus only consists of the strand strands La and Lc.

Anschließend wird die Abklebeeinrichtung 74, deren Rollen 90 und 92 sich ebenfalls in der gleichen Ebene senkrecht zur Spulenachse befinden, wie die Rolle 32 und die Schneide- und Halteeinrichtung 43, auf die Spule abgesenkt und mit definiertem Druck im Zylinder 72 gegen diese gepreßt.Subsequently, the masking device 74, the rollers 90 and 92 of which are also located in the same plane perpendicular to the coil axis as the roller 32 and the cutting and holding device 43, is lowered onto the coil and pressed against the cylinder 72 with a defined pressure.

Die Spule wird nun wieder in der üblichen Wickelrichtung gedreht und das äußere Litzenende mit Etiketten vom Etikettenband 91 festgeklebt. Da die Halte- und Schneideinrichtung die Litze immer an der gleichen Stelle durchtrennt, ist die Position des Litzenendes exakt vorgegeben.The spool is now rotated again in the usual winding direction and the outer end of the strand is stuck with labels from the label tape 91. Since the holding and cutting device always cuts the strand at the same point, the position of the strand end is precisely specified.

Nach dem Abkleben des äußeren Litzenendes wird die gesamte Manipulationseinrichtung 9 sowie die Verlegeeinrichtung 120 zum vorderen (in der Darstellung gemäß Fig. 1) Innenflansch der Spule 5 gefahren. Dann wird die Platte 51 nach unten verfahren und die Klemmeinrichtung 125 mit dem Stößel 55 (Fig. 6) über den Öffnungshebel 126 geöffnet. Dadurch löst sich das über den Flansch geführte innere Ende der auf der Spule 5 befindlichen Litze aus der Klemmeinrichtung. Um den Kontakt zwischen Stößel 55 und Hebel 126 zu bewirken, wird die Spule in Wickelrichtung gedreht, bis der Hebel 126 gegen den Stößel 55 stößt. Dann wird der Überwerfstift 65 in Kontakt mit dem Spulenflansch gebracht und die Spule entgegen ihrer üblichen Wickelrichtung gedreht, um das herausgeführte innere Ende auf die Wicklungen in der Spule zu legen. Die Abklebeeinrichtung 74 wird durch den Drehzylinder 87 um 180° geschwenkt und am Spuleninnenflansch in Kontakt mit der Wicklung gebracht. Dann wird das herausgeführte innere Ende der Litze mit den Etiketten vom Etikettenband 91 auf den Wicklungen festgeklebt. Dadurch ist die auf der Spule befindliche Litze vollständig von der Maschine und der Spuleinrichtung getrennt.After masking off the outer end of the strand, the entire manipulation device 9 and the laying device 120 are moved to the front (in the illustration according to FIG. 1) inner flange of the coil 5. Then the plate 51 is moved downward and the clamping device 125 with the plunger 55 (FIG. 6) is opened via the opening lever 126. As a result, the inner end of the stranded wire located on the coil 5 is released from the clamping device. In order to effect the contact between the plunger 55 and the lever 126, the coil is rotated in the winding direction until the lever 126 abuts the plunger 55. Then the coupling pin 65 is brought into contact with the coil flange and the coil is rotated counter to its usual winding direction in order to place the inner end which has been brought out on the windings in the coil. The masking device 74 is pivoted through the rotary cylinder 87 by 180 ° and brought into contact with the winding on the inner coil flange. Then the led out inner end of the strand with the labels from the label tape 91 is glued to the windings. As a result, the stranded wire located on the spool is completely separated from the machine and the spooling device.

Nun wird der Hubtisch 107 an der Säule 102 nach oben gefahren, bis das Gewicht der Spule auf den Tragblechen 109, 110 aufliegt. Die Pinolen der Spuleinrichtung werden geöffnet und die Spule nach unten gesenkt und durch eine Drehung um 90° in Richtung des Pfeiles 112 aus der Maschine herausbefördert. Die Spule steht dann auf den Tragblechen 109, 110, wobei die Längsachse parallel zur Zeichenebene in Fig. 1 ausgerichtet ist. Die volle Spule wird nun mit der Transporteinrichtung 11 ergriffen und in eine Warteposition gebracht und eine leere Spule auf den Hubtisch aufgesetzt. Dann schwenkt der Hubtisch zurück und wird wieder nach oben gefahren, so daß die Leerspule von der Spuleinrichtung gespannt werden kann.Now the lifting table 107 on the column 102 is moved upwards until the weight of the coil rests on the support plates 109, 110. The quills of the winding device are opened and the bobbin is lowered and conveyed out of the machine by rotating through 90 ° in the direction of arrow 112. The coil is then on the support plates 109, 110, the longitudinal axis being aligned parallel to the drawing plane in FIG. 1. The full bobbin is now gripped with the transport device 11 and brought into a waiting position and an empty bobbin is placed on the lifting table. Then the lifting table swings back and is moved up again, so that the empty spool can be tensioned by the winding device.

Sobald die Leerspule aufgenommen ist, wird die Schneide- und Halteeinrichtung 43 so weit ausgefahren, daß sich die daran gehaltene Litze bei einer Drehung der Spule in die an einer Mitnehmerscheibe 128 angeordnete Klemmeinrichtung 125 einklemmen kann. Gleichzeitig fährt die Greifeinrichtung 24 etwas in Richtung auf die Spule hin, so daß sich die Gesamtlänge der Litzenstränge La und Lc nicht ändert. Die Litze wird nun durch die Klemmeinrichtung 125 und die Greifeinrichtung 24 gehalten. Anschließend wird die Spule, wie Fig. 8 zeigt, entgegen der üblichen Wickelrichtung gedreht, wodurch sich die Litze L auf einen Ringvorsprung 133 an der Mitnehmerscheibe 128 auflegt. Dabei bewegt sich die Greifeinrichtung 24 auf die Spule zu. Sobald eine vorbestimmte Menge der Litze L auf den Ringvorsprung 133 aufgewickelt ist, wird die Manipulationseinrichtung mit der Greifeinrichtung 24 aus der in Fig. 8 gezeigten Position in den Wickelraum zwischen den Spuleninnenflanschen zurückbewegt. Dadurch wird die Litze L über die Klemmscheibe und den Flansch der Spule in den Wickelraum verbracht, wobei gleichzeitig auch die Verlegeeinrichtung 120 aus ihrer Position gemäß Fig. 8 zurückbewegt wird. Die Greifeinrichtung 24 fährt dann etwas weiter aus und wird parallel zur Spulenlängsachse vom vorderen Flansch wegbewegt, wodurch sich die Litze L von der Rolle 32 löst. Dann wird die Greifeinrichtung 24 in ihre Ausgangsposition zurückgebracht und die Doppelschlagverlitzmaschine gestartet.As soon as the empty bobbin is received, the cutting and holding device 43 is extended so far that the stranded wire held thereon can become jammed into the clamping device 125 arranged on a driving disk 128 when the bobbin rotates. At the same time, the gripping device 24 moves somewhat towards the spool, so that the total length of the strand strands La and Lc does not change. The strand is now held by the clamping device 125 and the gripping device 24. Then, as shown in FIG. 8, the coil is rotated counter to the usual winding direction, as a result of which the stranded wire L lies on an annular projection 133 on the drive plate 128. The gripping device 24 moves towards the coil. As soon as a predetermined amount of the strand L is wound onto the ring projection 133, the manipulation device with the gripping device 24 is moved back from the position shown in FIG. 8 into the winding space between the coil inner flanges. As a result, the stranded wire L is brought into the winding space via the clamping disk and the flange of the coil, the laying device 120 also being moved back out of its position according to FIG. 8. The gripping device 24 then extends a little further and is moved away from the front flange parallel to the longitudinal axis of the spool, as a result of which the strand L is detached from the roller 32. Then the gripping device 24 is returned to its starting position and the double-impact bunching machine is started.

Das vorliegende Ausführungsbeispiel wurde in bezug auf eine Doppelschlagverlitzmaschine erläutert. Es soll jedoch darauf hingewiesen werden, daß die Vorgangsweise prinzipiell bei allen Spuleinrichtungen angewendet werden kann, bei denen eine volle Spule gegen eine leere Spule gewechselt werden muß.The present embodiment has been explained with reference to a double-twist bunching machine. However, it should be pointed out that the procedure can in principle be applied to all winding devices in which a full bobbin has to be exchanged for an empty bobbin.
