Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen eine Verseilung aus wenigstens zwei SZ-verseilten Lagen mit einer der Anzahl der zu verseilenden Lagen entsprechenden Anzahl von Drallspeichern gemäß des Oberbegriffs der Anspruchs 1.The invention relates to a device for producing stranding from at least two SZ-stranded layers with one of the number the number of swirl stores corresponding to the layers to be stranded according to the preamble of claim 1.

Mehrlagige Verseilungen werden üblicherweise mit in Durchlaufrichtung des zu verseilenden Stranges hintereinander angeordneten Verseilmaschinen hergestellt, wobei zunächst mit einer Verseilmaschine eine erste Lage hergestellt wird. Um das Aufdrehen der SZ-verseilten Lage zu verhindern, ist es erforderlich, daß diese Lage z.B. mit einem sogenannten Bändchenspinner umwickelt wird. Auf diese fixierte erste Lage wird dann eine weitere Lage aufgebracht, auf die dann entweder eine Hülle aufextrudiert wird oder eine dritte Lage, wobei es in letzterem Fall ebenfalls wieder erforderlich ist, mit einem Bändchenspinner die zweite Lage zu fixieren, bevor die dritte Lage aufgebracht werden kann.Multi-layer strandings are usually included in the direction of flow of the strand to be stranded stranding machines arranged one behind the other manufactured, initially with a stranding machine a first layer is made. To unscrew the SZ-stranded To prevent position, it is necessary that this position e.g. With a so-called ribbon spinner is wrapped. Fixed on this Then another layer is applied to the first layer, onto which then either a sheath is extruded or a third layer where in the latter case it is also necessary again with a Ribbon spinner to fix the second layer before the third layer can be applied.

Das Fixieren der einzelnen Lagen z.B. mittels Bändchenspinner ist aber technisch aufwendig, wobei zusätzlich die Durchlaufgeschwindigkeit meist verringert werden muß, da die Bändchenspinner nicht eine so große Arbeitsgeschwindigkeit wie die Verseilmaschinen aufweisen. Eine Vorrichtung mit nur einem Verseilpunkt ist aus US-3187495-A bekannt.Fixing the individual layers e.g. using a ribbon spinner but technically complex, in addition the throughput speed usually has to be reduced, since the ribbon spinner is not one have the same working speed as the stranding machines. A device with only one stranding point is known from US-3187495-A known.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung zu verbessern, d.h. den technischen Aufwand möglichst klein und die Durchlaufgeschwindigkeit möglichst groß zu halten.The invention is therefore based on the object of a device to improve the genus mentioned at the beginning, i.e. the technical Effort as small as possible and the throughput speed as possible keep big.

Gelöst wird diese Aufgabe dadurch, daß nur ein Verseilpunkt vorgesehen ist, in dem die Adern der Lagen verseilt werden, daß die Drallspeicher hintereinander angeordnet sind, und daß jeder Drallspeicher mit einer Einlaufscheibe und einer Vereilscheibe versehen ist. Bei der erfindungsgemäßen Vorrichtung ist nur ein einziger Verseilpunkt vorgesehen, in dem gleichzeitig die Adern aller Lagen verseilt werden. Nach dem Verseilpunkt kann dann z.B., wie an sich üblich, eine Hülle auf den verseilten Strang aufextrudiert werden. This problem is solved in that only one stranding point is provided is in which the veins of the layers are stranded that the Swirl accumulators are arranged one behind the other, and that each swirl accumulator is provided with a washer and a washer. In the device according to the invention there is only a single stranding point provided in which the cores of all layers are twisted at the same time become. After the stranding point, for example, as usual, a sheath can be extruded onto the stranded strand.

Um alle Adern zum Verseilpunkt zu führen, kann in einer bevorzugten Ausführungsform der Erfindung eine Führung, mit der die Adern des in Durchlaufrichtung hinteren Drallspeichers zentral durch den vorderen Drallspeicher geführt werden, vorgesehen sein. Die Adern des oder der hinteren Drallspeicher werden zentrisch durch den oder die vorderen Drallspeicher geführt, also bereits in ringförmigen aber unverseilten Lagen, die den im Verseilpunkt herzustellenden, verseilten Lagen entsprechen.In order to lead all wires to the stranding point, a preferred one can be used Embodiment of the invention a guide with which the wires of the in Direction of flow of the rear swirl accumulator centrally through the front Swirl storage can be performed. The veins of the or the rear swirl storage are centered by the or the front swirl storage led, so already in annular but un stranded layers that stranded the one to be produced at the stranding point Locations correspond.

Bevorzugt ist dabei, wenn die Führung mit der Verseilscheibe verbunden ist und mit dieser gedreht wird. Die Führung kann im weitesten Sinne als verlängerte Verseilscheibe angesehen werden, die sich zentrisch durch den oder die nachfolgenden Drallspeicher erstreckt, was eine sehr einfache und zuverlässige Führung der Adern bis zum Verseilpunkt gewährleistet.It is preferred if the guide is connected to the stranding disk and is rotated with it. The leadership can be the broadest Senses can be viewed as an elongated extends centrally through the following swirl accumulator (s), which is a very simple and reliable guiding of the wires up to Stranded point guaranteed.

    Es versteht sich, daß anstelle der mit Bezug auf Fig. 1 dargestellten Drallspeicher 2, 3 auch jede andere Form eines Drallspeichers verwendet werden kann, wobei lediglich beispielhaft auf die in der EP A 582 802 beschriebenen Drallspeicher verwiesen wird.It is understood that instead of that shown with reference to FIG. 1 Swirl storage 2, 3 also any other form of swirl storage can be used, only as an example to the in the Swirl memory described in EP A 582 802.

    Die Adern 16 des hinteren Drallspeichers 2 und die Adern 17 des vorderen Drallspeichers 3 werden alle zu einem gemeinsamen Verseilpunkt 18 geführt, der als ösenförmiger Verseilnippel 19 ausgeführt ist. Um die Adern 16 des hinteren Drallspeichers 2 zum Verseilpunkt 18 zu führen, ist mit der Verseilscheibe 6 des hinteren Drallspeichers 2 eine Führung 20 drehfest verbunden, die sich zentral durch den Drallspeicher 3 erstreckt.The wires 16 of the rear swirl storage 2 and the wires 17 of the front swirl accumulator 3 all become a common stranding point 18 out, which is designed as an eyelet stranding nipple 19 is. Around the wires 16 of the rear swirl accumulator 2 to the stranding point 18 to lead, with the stranding disk 6 of the rear swirl accumulator 2 a guide 20 non-rotatably connected, which is centrally through the swirl accumulator 3 extends.

    Die Speicherscheiben 5 weisen, wie an sich bekannt, Bohrungen 21 auf, durch welche die Adern 16, 17 geführt sind. Die Verseilscheiben 6, 7 weisen ebenfalls Bohrungen 22 auf, durch welche die Adern 16, 17 geführt sind. Die Führung 20 ist mit ihrem vorderen, dem Verseilpunkt 18 zugewandten Ende 23 in der Verseilscheibe 22 des vorderen Drallspeichers 3 drehbar gelagert, wie in Fig. 2 in vergrößertem Maßstab zu sehen ist. Um die Adern 16 an der Führung 20 zu führen, sind im Bereich des vorderen Endes 23 der Führung 20 weitere Bohrungen 24 an ringförmigen Stegen 25 angebracht, durch welche die Adern 16 geführt sind, bevor sie in den Verseilnippel 19 einlaufen. Je nach Länge der Führung 20 und deren Drehzahl können zwischen den Bohrungen 24 im Bereich des vorderen Endes 23 und den Bohrungen 22 in der Verseilscheibe 6 weitere Stege 25 mit Bohrungen 24 vorgesehen sein.As is known per se, the storage disks 5 have bores 21 through which the wires 16, 17 are guided. The stranding washers 6, 7 also have bores 22 through which the wires 16, 17 are performed. The guide 20 is with its front, the stranding point 18 facing end 23 in the stranding disk 22 of the front Swirl storage 3 rotatably mounted, as in Fig. 2 in an enlarged Scale can be seen. In order to guide the wires 16 on the guide 20, are 20 more holes in the region of the front end 23 of the guide 24 attached to annular webs 25 through which the veins 16 are guided before they enter the stranding nipple 19. ever according to the length of the guide 20 and its speed can between Bores 24 in the area of the front end 23 and the bores 22 6 additional webs 25 with holes 24 are provided in the stranding disk his.

    In alternativen, in den Zeichnungen nicht dargestellten Ausführungsformen der Erfindung kann die Führung 20 auch als außen glattes Rohr ausgeführt sein, an welchem die Adern 16 anliegen. Weiters ist es möglich, daß an Stelle der Stege 25 mit den Bohrungen 24 durchgehende Rohre eines für jede Ader 16 vorgesehen sind. Es ist auch möglich, die Führung 20 als Rohr auszuführen, in welchem an der äußeren Mantelfläche längslaufende Nuten angebracht sind, in welchen die Adern 16 laufen.In alternative embodiments not shown in the drawings According to the invention, the guide 20 can also be an externally smooth tube be carried out on which the wires 16 rest. Furthermore, it is possible that instead of the webs 25 with the holes 24 continuous Tubes one for each wire 16 are provided. It is also possible to run the guide 20 as a tube, in which on the outer circumferential surface longitudinal grooves are attached, in which the wires 16 run.

    In Fig. 3 ist ausschnittweise eine Ausführungsform einer erfindungsgemäßen Vorrichtung im Bereich des verseilpunktes 18 dargestellt, mit der eine SZ-Verseilung aus drei Lagen hergestellt werden kann, wofür es erforderlich ist, daß drei Drallspeicher hintereinander angeordnet sind. Dies bedeutet, daß durch die Drallspeicher 2, 3 von Fig. 1 eine weitere Führung 27 zentral durchgeführt ist, die ebenfalls im Bereich der Verseilscheibe 7 des vordersten Drallspeichers 3 endet. Der Drallspeicher der innersten, ersten Lage ist entsprechend den Drallspeichern 2, 3 der beiden äußeren Lagen ausgeführt. Die Adern 26 der ersten bzw. innersten Lage werden dabei durch eine Führung 27 geführt, die Rohre 28 aufweist, die an einem Trägerrohr 29 befestigt sind.In Fig. 3 is a detail of an embodiment of an inventive Device shown in the area of stranding point 18, with which SZ stranding can be made from three layers, for which it is necessary that three swirl accumulators in a row are arranged. This means that by the swirl storage 2, 3 of Fig. 1 another guide 27 is performed centrally, which also in the area of the stranding disk 7 of the foremost swirl accumulator 3 ends. The swirl accumulator of the innermost, first layer is corresponding the swirl stores 2, 3 of the two outer layers. The wires 26 of the first or innermost layer are covered by a Guide 27 guided, the tubes 28, which on a support tube 29 are attached.

    Durch die Führungen 20, 27 werden auch die Adern 16, 26 der hinteren Drallspeicher im unverseilten Zustand bis zum Verseilpunkt 18 geführt und dort gleichzeitig mit den Adern 17 des vordersten Drallspeichers 3 in drei Lagen verseilt. Durch die erfindungsgemäße Vorrichtung werden Halte- oder Sicherungsmaßnahmen der SZ-Verseilung, z.B. mittels Bändchenspinner der inneren Lagen entbehrlich. Des weiteren bietet sich der erhebliche Vorteil, daß die einzelnen Drallspeicher bzw. Verseilscheiben gegebenenfalls mit den ihnen zugeordneten Führungen so angetrieben werden können, daß z.B. bei gleicher Schlaglänge aller Lagen die Wendepunkte der einzelnen Lagen genau definiert zueinander, z.B. genau übereinander hergestellt werden können, was bei mehrlagigen SZ-Verseilungen, bei welchen die einzelnen Lagen unabhängig voneinander verseilt werden, nicht gewährleistet ist.Through the guides 20, 27, the wires 16, 26 of the rear Swirl storage in the unswaged state led to the stranding point 18 and there simultaneously with the wires 17 of the foremost swirl storage 3 stranded in three layers. By the invention Device are holding or securing measures of SZ stranding, e.g. the inner layers can be dispensed with using a ribbon spinner. Furthermore, there is the considerable advantage that the individual Swirl storage or stranding disks, if necessary, with them associated guides can be driven so that e.g. at the same lay length of all layers the turning points of the individual layers well defined to each other, e.g. made exactly on top of each other can be what with multilayer SZ stranding, in which the individual layers are stranded independently of one another, not guaranteed is.

    Die Führungen 20, 27 sind rohrförmig ausgeführt, damit ein Kern, beispielsweise ein bereits verseiltes Kabel, durchgeführt werden kann, auf welches dann weitere Lagen aufgebracht werden.The guides 20, 27 are tubular so that a core, for example, an already stranded cable can, on which then further layers are applied.

    Zusammenfassend kann ein bevorzugtes Ausführungsbeispiel der erfindungsgemäßen Vorrichtung wie folgt beschrieben werden:In summary, a preferred embodiment of the invention Device can be described as follows:

    Zum Herstellen einer Verseilung aus mehreren SZ-verseilten Lagen weist eine Vorrichtung eine der Anzahl der zu verseilenden Lagen entsprechende Anzahl von Drallspeichern 2, 3 auf, die hintereinander angeordnet sind. Die Verseilscheibe 6 des in Durchlaufrichtung (Pfeil 1) hinteren Drallspeichers 2 weist eine Verlängerung 20 als Führung auf, die sich zentral durch den vorderen Drallspeicher 3 bis zu dessen Verseilscheibe 7 erstreckt.For producing stranding from several SZ stranded layers a device has one of the number of layers to be stranded corresponding number of swirl stores 2, 3, one after the other are arranged. The stranding disk 6 in the direction of travel (Arrow 1) rear swirl accumulator 2 has an extension 20 as Leadership, which is central through the front swirl storage 3 to extends to the stranding disk 7.

    Es ist nur ein einziger Verseilpunkt 18 in Form eines Verseilnippels 19 vorgesehen, in welchem gleichzeitig alle Adern 16, 17 zu den einzelnen Lagen verseilt werden. Durch diese Anordnung ist es möglich, auf Maßnahmen zu verzichten, die beim Stand der Technik erforderlich sind, um das Aufdrehen einer verseilten Lage zu verhindern, bevor die nächste Lage aufgebracht wird.It is only a single stranding point 18 in the form of a stranding nipple 19 provided, in which all the wires 16, 17 to the individual layers are stranded. With this arrangement it is possible to dispense with measures that are required in the prior art are to prevent a stranded layer from being unscrewed, before the next layer is applied.
