Abstract

The invention relates to a process and a device for winding and/or unwinding multi-wire coils (10) in which several wires (3), especially wires (3) of low plastic deformability, like steel wires, are simultaneously wound on a multi-wire coil (10) and/or such wound wires (3) can simultaneously be unwound in the stranding device (12) and subsequently stranded. It is to be possible for the wires (3) to be double-twist stranded together while maintaining quality, i.e. ensuring the same length ratios in the wire layers on the multi-wire stranding principle on highly productive stranding machines. This is attained in that, during the winding process in a winding device (1), individual wires (3) are taken from stationary feeds (2) and taken to a dedicated compensating storage device (7) and several of said wires (3) are wound at a bunch of approximately parallel wires (3) on a common multi-wire coil (10), and during the unwinding of the bunch of wires (3) from a multi-wire coil (10) thus wound which is received in an unwinding device of a stranding device designed as a coil support (19) the individual wires (3) are taken to a stranding process via a dedicated compensating storage device (7').

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Bewickeln und/oder Abwickeln von Mehrdrahtspulen, wobei mehrere Drähte geringer plastischer Verformbarkeit, wie Stahldrähte, gleichzeitig auf eine Mehrdrahtspule gewickelt und/oder derart aufgewickelte Drähte gleichzeitig in Verseileinrichtungen abgewickelt und anschließend verseilt werden.The invention relates to a method and a device for winding and / or unwinding multi-wire coils, wherein several wires of low plastic deformability, such as steel wires, are simultaneously wound onto a multi-wire coil and / or wires so wound up are simultaneously unwound in stranding devices and then stranded.

Zur Herstellung von Drahtlitzen werden in der Praxis solche Verfahren angewendet, die sich in drei Etappen, nämlich Ziehen, Transportieren und Verseilen, mit den dazugehörigen Auf- und Abwickelvorgängen, untergliedern.
Durch die EP 0 493 212 A1 ist eine Vorrichtung zum Ziehen von Metalldrähten bekannt, die ihrerseits einen Drahtziehblock mit zugehörigem Glüher und einen Spuler bzw. Drahtzieh- und Glühblöcke sowie einen gemeinsamen Spuler aufweist. Die Anordnung von Glüheinrichtungen weist darauf hin, dass hier plastisch verformbare Drähte , wie z. B. Cu-Drähte, hergestellt werden sollen. Stahldrähte, d. h., Drähte mit einer geringen plastischen Verformbarkeit werden während des Ziehprozesses niemals geglüht.
Durch die DE 21 39 244 A1 ist es bekannt, mehreren Drahtziehmaschinen eine Abzieheinrichtung mit Vorratsspule zuzuordnen, wobei die Anzahl der Drahtziehmaschinen der Anzahl der Drähte der herzustellenden Litze oder des Seiles entspricht. Die einzelnen hergestellten Drähte werden gleichzeitig auf eine gemeinsame Vorratsspule aufgewickelt. Im Anschluß daran werden die Drähte, wiederum gleichzeitig, von solchen stationär angeordneten Vorratsspulen abgezogen und einer Verseilmaschine zugeführt.
Ferner ist es durch die DE 39 22 974 A1 bekannt, mit einer Drahtziehmaschine mehrere Drähte gleichzeitig zu ziehen und diese als Gesamtmenge oder unterteilt in Teilmengen einer oder mehreren Wickeleinrichtungen zuzuführen, auf denen jeweils eine Vielzahl von Drähten als Bündel gemeinsam oder als Einzeldrähte aufgewickelt werden.
In practice, such processes are used to produce wire strands, which are divided into three stages, namely pulling, transporting and stranding, with the associated winding and unwinding processes.
EP 0 493 212 A1 discloses a device for drawing metal wires, which in turn has a wire drawing block with associated glow plug and a winder or wire drawing and glow plug blocks as well as a common winder. The arrangement of glow devices indicates that plastically deformable wires such. B. Cu wires to be produced. Steel wires, ie wires with a low plastic deformability, are never annealed during the drawing process.
From DE 21 39 244 A1 it is known to assign a pulling device with a supply spool to several wire drawing machines, the number of wire drawing machines corresponding to the number of wires of the strand or rope to be produced. The individual wires produced are simultaneously wound onto a common supply spool. Subsequently, the wires are drawn off, again simultaneously, from such stationary supply spools and fed to a stranding machine.
Furthermore, it is known from DE 39 22 974 A1 to draw several wires simultaneously with a wire drawing machine and to feed these as a total or divided into partial quantities to one or more winding devices, on each of which a plurality of wires are wound together as a bundle or as individual wires.

Mit dem Verfahren soll eine Produktivitätssteigerung in der drahtherstellenden und - verarbeitenden Industrie erreicht werden. Bei Drähten mit einer geringen plastischen Verformbarkeit, wie Stahldrähten, wird jeder Draht des Drahtbündels während des Wickelvorganges durch verschiedene Wickelparameter beeinflußt. Die Beeinflussung tritt beispielsweise durch die unterschiedliche Oberflächenstruktur im Auflaufbereich der einzelnen Drähte auf der Wickelspule ein. Es werden demzufolge auch unterschiedliche Längen und Spannungszustände pro Zeiteinheit und Draht erzeugt. Wenn so bewickelte Mehrdrahtwickelspulen in Verseilmaschinen als Ablaufspulen eingesetzt werden, ist eine Einhaltung gleicher Längen der Einzeldrähte und damit eine qualitätsgerechte Verseilung der Drähte zu Litzen nicht gewährleistet. Derartig gewickelte Stahldrahtbündel entsprechen nicht den Anforderungen, die an eine weitere qualitätsgerechte Verseilung auf hochproduktiven Doppelschlagverseilmaschinen, wie sie durch die EP 0 563 586 bekannt sind, gestellt werden.The process is intended to increase productivity in the wire manufacturing and processing industry. In the case of wires with low plastic deformability, such as steel wires, each wire of the wire bundle is influenced by various winding parameters during the winding process. This is influenced, for example, by the different surface structure in the run-up area of the individual wires on the winding spool. As a result, different lengths and voltage states are generated per unit of time and wire. If multi-wire winding spools wound in this way are used as winding spools in stranding machines, it is not possible to ensure that the individual wires are of the same length, and thus that the wires are stranded in a quality-appropriate manner. Steel wire bundles wound in this way do not meet the requirements placed on a further quality-oriented stranding on highly productive double-twist stranding machines, as are known from EP 0 563 586.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum gleichzeitigen Bewickeln einer Mehrdrahtspule mit mehreren Drähten geringer plastischer Verformbarkeit, wie Stahldrähten und/oder gleichzeitigen Abwickeln solcher Drähte von einer derart bewickelten Mehrdrahtspule für eine nachfolgende Verseilung derselben, zu schaffen, bei der die Drähte qualitätsgerecht, d. h., bei Sicherung gleicher Längenverhältnisse in den Drahtlagen, nach dem Prinzip der Mehrdrahtverseilung auf hochproduktiven Verseilmaschinen im Doppelschlag miteinander verseilt werden können.The invention has for its object to provide a method and an apparatus for the simultaneous winding of a multi-wire coil with several wires of low plastic deformability, such as steel wires and / or simultaneous unwinding of such wires from a multi-wire coil so wound for subsequent stranding, in which the Wires of high quality, d. In other words, when securing the same length ratios in the wire layers, the principle of multi-wire stranding can be twisted together on highly productive stranding machines.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass

  • während des Bewickelvorganges in einer Wickeleinrichtung einzelne Drähte von stationären Abläufen ablaufen,
  • nachfolgend die einzelnen Drähte zur Erzielung gleicher Drahtlängen auf der Mehrdrahtspule zu einem Bündel von Drähten zusammengefaßt werden und
  • dieses Bündel von Drähten einem Überdrehvorgang unterworfen wird,
  • anschließend das Bündel von Drähten über eine Abzug-Tänzereinrichtung geführt sowie auseinandergefacht wird,
  • sämtliche Drähte jeweils über eine eigene Tänzerspeichereinrichtung geführt sowie weiterhin
  • über eine Verlegung als Bündel annähernd parallel nebeneinander angeordneter Drähte einem geregelten Mehrdrahtwickler zugeführt und dort auf die Mehrdrahtspule aufgewickelt werden und
  • dass während des Abwickelns des Bündels von Drähten von einer derart bewickelten Mehrdrahtspule, die ihrerseits von einer als Spulenträger ausgebildeten Abwickeleinrichtung einer Verseileinrichtung in Form einer Doppelschlagverseilmaschine aufgenommen wird, die einzelnen Drähte über jeweils eine eigene Tänzerspeichereinrichtung dem Verseilvorgang zugeführt werden.
According to the invention the object is achieved in that
  • during the winding process, individual wires run off stationary processes in a winding device,
  • The individual wires are subsequently combined to form a bundle of wires to achieve the same wire lengths on the multi-wire coil
  • this bundle of wires is subjected to an overturning process,
  • then the bundle of wires is passed over a trigger dancer device and is spread apart,
  • all the wires each have their own dancer storage device and continue to do so
  • via a laying as a bundle of wires arranged approximately parallel to one another, fed to a regulated multi-wire winder and wound up there on the multi-wire coil and
  • that during the unwinding of the bundle of wires from a multi-wire spool wound in this way, which in turn is taken up by an unwinding device of a stranding device in the form of a double-stranding machine designed as a coil carrier, the individual wires are each fed to the stranding process via their own dancer storage device.

In einer Weiterbildung der Erfindung laufen die einzelnen Drähte von den stationären Abläufen ab und werden mittels einer Drahtzieheinrichtung in Form einer Mehrdrahtziehmaschine und/oder mehrerer Einzeldrahtziehmaschinen auf den gewünschten Drahtdurchmesser gezogen und anschließend jeweils der eigenen Tänzerspeichereinrichtung zugeführt.In a further development of the invention, the individual wires run from the stationary processes and are drawn to the desired wire diameter by means of a wire drawing device in the form of a multi-wire drawing machine and / or several individual wire drawing machines, and then each fed to their own dancer storage device.

Es ist weiterhin vorgesehen, dass die einzelnen von stationären Abläufen ablaufenden Drähte zur Erzielung gleicher Drahtlängen auf der Mehrdrahtspule über eine eigene jeweils getrennt angetriebene und geregelte Ziehscheibe geführt und anschließend jeweils über eine eigene Tänzerspeichereinrichtung einer gemeinsamen Abzugsscheibe mit Andrückrolle zugeführt werden, wobei die Drähte annähernd parallel nebeneinander liegend, die Abzugsscheibe in einer oder mehreren Windungen umschlingen und nachfolgend als Bündel annähernd parallel nebeneinander angeordneter Drähte dem geregelten Mehrdrahtwickler zugeführt und dort auf die Mehrdrahtspule aufgewickelt werden.It is further contemplated that the individual wires running from stationary processes are guided over their own separately separately driven and regulated drawing disk to achieve the same wire lengths on the multi-wire spool and then each fed to a common take-off disk with pressure roller via its own dancer storage device, the wires being approximately parallel lying next to each other, looping around the take-off disk in one or more turns and subsequently fed to the regulated multi-wire winder as a bundle of wires arranged approximately parallel to one another and wound there onto the multi-wire coil.

Eine weitere erfindungsgemäße Ausbildung besteht darin, dass die mit dem Bündel von annähernd parallel nebeneinander angeordneten Drähten bewickelte Mehrdrahtspule in der als Spulenträger ausgebildeten Abwickeleinrichtung der Verseileinrichtung gelagert wird, wobei während der Verseilung das Bündel von Drähten mit konstanter Spannung abgezogen und auseinandergefacht wird, sowie jeder Draht über jeweils eine eigene Tänzerspeichereinrichtung geführt wird und abschließend sämtliche zu verseilenden Drähte in einem einzigen Verseilpunkt im Doppelschlag zu der in ihrer Struktur fertigen Drahtlitze verseilt und nach Durchlauf von zwei synchron zueinander rotierenden Flyern einer Aufwickeleinrichtung zugeführt werden.A further embodiment according to the invention consists in that the multi-wire coil wound with the bundle of wires arranged approximately parallel to one another is stored in the unwinding device of the stranding device, which is designed as a coil carrier, the bundle of wires being pulled and unfolded with constant tension during the stranding, as well as each wire is guided over each of its own dancer storage device and finally all the wires to be stranded are twisted in a single stranding point in a double lay to form the stranded wire strand and after passage are fed to a winding device by two flyers rotating synchronously with one another.

Vorteilhafterweise wird während der Verseilung das Bündel von Drähten mit konstanter Spannung von der Mehrdrahtspule abgezogen und zur Erzielung einer geringen Drahtzugkraft flaschenzugförmig über ein Rollensystem sowie eine Betätigungsrolle einer Drahtzugbremse geführt, wobei im Anschluß daran die einzelnen Drähte auseinandergefacht und über ihre zugehörige Tänzerspeichereinrichtung geführt und infolge einer Gleit- und Abwälzbewegung auf einer konischen Umlenkrolle in einem einzigen Verseilpunkt im Doppelschlag zu der in ihrer Struktur fertigen Drahtlitze verseilt werden und wobei die in ihrer Struktur fertige Drahtlitze bei Durchlauf von zwei synchron zueinander rotierenden Flyern in doppelter Drehzahl der Flyer um sich selbst rotiert, die Drahtlitze gegebenenfalls vor ihrem Aufwickeln zum Abbau ihrer inneren Torsionsspannung einem oder mehreren Überdrehvorgängen und/oder einem definierten Zugkraftanstieg und/oder einem oder mehreren Nachformvorgängen unterworfen und abschließend mit gleichbleibender Wickelkraft einer geregelten Aufwickeleinrichtung zugeführt wird.Advantageously, the bundle of wires with constant voltage is drawn off from the multi-wire coil during the stranding and, in order to achieve a low wire tensile force, guided in a pulley-like manner via a roller system and an actuating roller of a wire pull brake, the individual wires subsequently being disassembled and guided over their associated dancer storage device and as a result of one Sliding and rolling movement on a conical deflection roller are twisted in a single twist point in a double lay to the wire strand finished in its structure, and the wire strand finished in its structure rotates around itself when two flyers rotating in synchronism with each other pass through at double speed Before being wound up, wire strand may be subjected to one or more over-tightening processes and / or a defined increase in tensile force and / or one or more post-forming processes to reduce its internal torsional tension and finally with a constant winding force is fed to a regulated winding device.

Eine annähernd gleiche Länge der Drähte ist auch dadurch erreichbar, dass die, von den stationären Abläufen ablaufenden und gegebenenfalls mittels der Drahtzieheinrichtung auf den gewünschten Drahtdurchmesser gezogenen Drähte als Bündel von Drähten mit einer Drehzahl, die eine Verformung der Drähte im elastischen Bereich zuläßt, überdreht werden.An approximately equal length of the wires can also be achieved by overturning the wires running from the stationary processes and possibly drawn to the desired wire diameter by means of the wire pulling device as a bundle of wires at a speed that allows the wires to be deformed in the elastic range .

Um jede beliebige Drahtlitzenkombination zu realisieren, können die Drähte, die von der auf dem Spulenträger angeordneten Mehrdrahtspule ablaufen, mit weiteren Drähten und/oder Litzen, die von Einzel- und/oder Mehrdrahtspulen ablaufen und die ihrerseits auf einem oder mehreren Spulenträgern gelagert sind, gemeinsam verseilt werden.In order to implement any combination of wire strands, the wires that run from the multi-wire coil arranged on the coil carrier can be shared with other wires and / or strands that run from single and / or multi-wire coils and which in turn are mounted on one or more coil carriers be stranded.

Gemäß einer weiteren Ausgestaltung der Erfindung werden die einzelnen Drähte und/oder Litzen vor Einlauf in den Verseilpunkt einer Vorformung unterworfen.According to a further embodiment of the invention, the individual wires and / or strands are subjected to a preforming before entering the stranding point.

Es ist auch möglich, die in ihrer Struktur fertige Drahtlitze im Bereich zwischen dem Verseilpunkt und der konischen Umlenkrolle einer elastischen Umformung durch Überdrehung zu unterwerfen.It is also possible to subject the stranded wire structure in its area between the stranding point and the conical deflecting roller to elastic deformation by overtightening.

In einer weiteren Ausbildung der Erfindung umfaßt diese eine Vorrichtung zum gleichzeitigen Bewickeln einer Mehrdrahtspule mit mehreren Drähten geringer plastischer Verformbarkeit, wie Stahldrähten und/oder gleichzeitigem Abwickeln solcher Drähte von einer derart bewickelten Mehrdrahtspule für eine nachfolgende Verseilung derselben, so auszubilden, dass die Vorrichtung zum Bewickeln einer Mehrdrahtspule eine Wickeleinrichtung und/oder zum Abwickeln einer Mehrdrahtspule eine Verseileinrichtung in Form einer Doppelschlagverseilmaschine aufweist, wobei die Wickeleinrichtung stationäre Abläufe für die einzelnen Drähte, gegebenenfalls eine diesen nachgeordnete Drahtzieheinrichtung sowie mindestens einen Mehrdrahtwickler mit Mehrdrahtspule und die Verseileinrichtung mindestens eine Abwickeleinrichtung in Form eines Spulenträgers und eine Aufwickeleinrichtung aufweisen, und dass jedem der von stationären Abläufen der Wickeleinrichtung ablaufenden Drähte zwischen den Abläufen oder gegebenenfalls der Drahtzieheinrichtung und dem Mehrdrahtwickler mit der Mehrdrahtspule und jedem der von einer Mehrdrahtspule ablaufenden Drähte ortsfest an der Abwickeleinrichtung, in Form des Spulenträgers der Verseileinrichtung oder in Drahtlaufrichtung orstfest hinter dem Spulenträger eine Tänzerspeichereinrichtung zugeordnet ist und dass ferner zur Erzielung gleicher Drahtlängen auf der Mehrdrahtspule zwischen den Abläufen oder der Drahtzieheinrichtung der Wickeleinrichtung und den Tänzerspeichereinrichtungen in Drahtlaufrichtung nacheinander eine Überdreheinrichtung und eine Abzug-Tänzereinrichtung angeordnet sind.In a further embodiment of the invention, this comprises a device for simultaneously winding a multi-wire coil with a plurality of wires of low plastic deformability, such as steel wires and / or simultaneously unwinding such wires from a multi-wire coil wound in this way for subsequent stranding thereof, in such a way that the device for winding a multi-wire spool has a winding device and / or for unwinding a multi-wire spool has a stranding device in the form of a double-twist stranding machine, the winding device having stationary processes for the individual wires, optionally a downstream wire drawing device and at least one multi-wire winder with multi-wire coil and the stranding device at least one unwinding device in the form of a spool holder and have a winding device, and that each of the wires running from stationary runs of the winding device between the processes ode r if necessary, a dancer storage device is assigned to the wire-drawing device and the multi-wire winder with the multi-wire coil and each of the wires running from a multi-wire coil stationary on the unwinding device, in the form of the bobbin of the stranding device or in the wire running direction behind the bobbin and in order to achieve the same wire lengths on the multiple wire An overturning device and a take-off dancer device are arranged one after the other between the processes or the wire pulling device of the winding device and the dancer storage devices in the wire running direction.

Weiterhin kann zur Erzielung gleicher Drahtlängen auf der Mehrdrahtspule zwischen den Abläufen oder der Drahtzieheinrichtung und den Tänzerspeichereinrichtungen, jedem Draht eine eigene, jeweils getrennt angetriebene und geregelte Ziehscheibe zugeordnet sein und in Drahtlaufrichtung hinter der Tänzerspeichereinrichtung eine gemeinsame Abzugsscheibe mit Andrückrolle und nachfolgend die Verlegung und der geregelte Mehrdrahtwickler mit Mehrdrahtspule angeordnet sein.Furthermore, in order to achieve the same wire lengths on the multi-wire spool between the processes or the wire drawing device and the dancer storage devices, each wire can be assigned its own, separately driven and controlled drawing disk and in the wire running direction behind the dancer storage device a common take-off disk with pressure roller and subsequently the laying and the regulated one Multi-wire winders with multi-wire coil can be arranged.

Es ist möglich, dass die Drahtzieheinrichtung eine Mehrdrahtziehmaschine und/oder mehrere Einzeldrahtziehmaschinen aufweist.It is possible that the wire drawing device has a multi-wire drawing machine and / or several single-wire drawing machines.

Zweckmäßigerweise ist jeder Abwickeleinrichtung in Form eines Spulenträgers direkt ein Rollensystem mit Betätigungsrolle für die Drahtzugbremse nachgeordnet, wobei über dieses Rollensystem jeder ablaufende Draht in einer oder mehreren Windungen geführt ist.Advantageously, each unwinding device in the form of a bobbin is directly followed by a roller system with an actuating roller for the wire pull brake, with each running wire being guided in one or more turns via this roller system.

Die Tänzerspeichereinrichtungen können jeweils separat gelagert sein und mindestens eine mit einstellbaren Kräften belastbare Tänzerrolle aufweisen.The dancer storage devices can each be stored separately and have at least one dancer roll that can be loaded with adjustable forces.

Es ist vorteilhaft, dass zwischen der Tänzerspeichereinrichtung und dem Verseilpunkt gegebenenfalls eine Vorformeinrichtung sowie zwischen dem Verseilpunkt und der konischen Umlenkrolle eine Dralliereinrichtung angeordnet ist und die nach dem Verseilen in ihrer Struktur fertige Drahtlitze vor dem Aufwickeln über eine oder mehrere Überdreheinrichtungen und/oder Nachformeinrichtungen und/oder einen definierten Zugkraftanstieg erzeugenden Doppelscheibenabzug geführt ist.It is advantageous that a preforming device is optionally arranged between the dancer storage device and the stranding point, and a twisting device is arranged between the stranding point and the conical deflecting roller, and the stranded wire structure that is produced after stranding is wound up via one or more overturning devices and / or postforming devices and / or before winding or a double disc trigger that generates a defined increase in tractive force.

Vorzugsweise weisen sämtliche Umlenk- und Führungsrollen sowohl der Wickel- als auch der Verseileinrichtung, über die mehrere Drähte in annähernd paralleler Anordnung nebeneinander geführt werden, eine oder mehrere Führungsrillen mit flachem Rollenquerschnitt auf.All deflection and guide rollers of both the winding and the stranding device, via which a plurality of wires are guided next to one another in an approximately parallel arrangement, preferably have one or more guide grooves with a flat roller cross section.

Die Verseileinrichtung, die die Abwickeleinrichtung beinhaltet, kann eine Doppelschlagverseilmaschine nach dem Prinzip "in-out" oder "out-in" sein.The stranding device which contains the unwinding device can be a double-twist stranding machine according to the "in-out" or "out-in" principle.

Mit der erfindungsgemäßen Lösung wird erreicht, dass bei einem gleichzeitigen Aufwickeln von Drähten geringer plastischer Verformbarkeit, wie Stahldrähten, auf Mehrdrahtspulen, die aufzuwickelnden Drähte annähernd gleiche Längen aufweisen. Dennoch vorhandene geringe Unterschiede in der Drahtlänge werden beim Abwickeln der Drähte in den Verseileinrichtungen kompensiert. Dadurch wird eine qualitätsgerechte Verseilung bei hochproduktiven Doppelschlagverseilmaschinen erreicht.With the solution according to the invention it is achieved that with simultaneous winding of wires of low plastic deformability, such as steel wires, on multi-wire coils, the wires to be wound have approximately the same lengths. However, slight differences in wire length are compensated for when the wires are unwound in the stranding devices. This ensures high-quality stranding in highly productive double-strand stranding machines.

Die Fig. 1 zeigt eine zur Vorrichtung gehörende Wickeleinrichtung 1 in einer bevorzugten Ausführungsform, die mehrere stationäre Abläufe 2 für Drähte 3, eine Überdreheinrichtung 4, eine Abzug-Tänzereinrichtung 5, ein oder mehrere Führungsmittel 6, Tänzerspeichereinrichtungen 7, eine Verlegung 8 und einen geregelten Mehrdrahtwickler 9 mit Mehrdrahtspule 10 aufweist.1 shows a winding device 1 belonging to the device in a preferred embodiment, which has a plurality of stationary runs 2 for wires 3, an overturning device 4, a take-off dancer device 5, one or more guide means 6, dancer storage devices 7, a laying 8 and a regulated one Has multi-wire winder 9 with multi-wire coil 10.

Alternativ kann gemäß Fig. 2 zwischen den stationären Abläufen 2 und der Überdreheinrichtung 4 eine Drahtzieheinrichtung 11 in Form einer Mehrdrahtziehmaschine angeordnet sein, mit der die einzelnen ablaufenden Drähte 3 auf den gewünschten Drahtdurchmesser gezogen werden können. Die Drahtzieheinrichtung 11 kann auch eine Anzahl von Einzeldrahtziehmaschinen aufweisen. Die stationären Abläufe 2 ihrerseits können beispielsweise als Coils (Fig. 1) oder Tangentialabläufe (Fig. 2) ausgeführt sein.Alternatively, as shown in FIG. 2, a wire drawing device 11 in the form of a multi-wire drawing machine can be arranged between the stationary processes 2 and the overturning device 4, with which the individual running wires 3 can be drawn to the desired wire diameter. The wire drawing device 11 can also be a number of single wire drawing machines exhibit. The stationary processes 2, in turn, can be designed, for example, as coils (FIG. 1) or tangential processes (FIG. 2).

Während des Wickelprozesses werden die von den stationären Abläufen 2 ablaufenden Drähte 3 direkt oder über die Drahtzieheinrichtung 11 (Fig. 2) der Überdreheinrichtung 4 zugeführt und als Bündel von Drähten 3 gemeinsam einem Überdreh-vorgang unterworfen, wobei der Überdrehvorgang mit einer Drehzahl erfolgt die eine Verformung der Drähte 3 im elastischen Bereich zuläßt. Damit wird erreicht, daß die Drähte 3 bei dem folgenden Eintritt in die Abzug-Tänzereinrichtung 5, die eine Abzugsscheibe 5a und eine Tänzerscheibe 5b aufweist, annähernd gleiche Längen aufweisen.During the winding process, the wires 3 running from the stationary processes 2 are fed directly or via the wire pulling device 11 (FIG. 2) to the overturning device 4 and, as a bundle of wires 3, are jointly subjected to an overturning process, the overturning process taking place at one speed Allows deformation of the wires 3 in the elastic range. It is thereby achieved that the wires 3 have approximately the same lengths when they subsequently enter the trigger dancer device 5, which has a trigger disk 5a and a dancer disk 5b.

Anschließend wird das Bündel von Drähten 3 dem Führungsmittel 6 zugeführt. Im vorliegenden Fall ist das Führungsmittel 6 als eine Führungsrolle ausgebildet. Bei Verlassen des Führungsmittels 6 wird das Bündel auseinandergefacht. Die einzelnen Drähte 3 werden der jeweils zugehörigen ortsfest angeordneten Tänzerspeichereinrichtung 7 und weiter in annähernd paralleler Anordnung nebeneinander über eine Verlegung 8 einer nicht näher dargestellten, an sich bekannten Verlegeeinrichtung der Mehrdrahtspule 10 eines Mehrdrahtwicklers 9 zugeführt. Mit der jedem Draht 3 zugeordneten Tänzerspeichereinrichtung 7 ist gewährleistet, daß während des Bewikkelvorganges der Mehrdrahtspule 10 noch eventuell vorhandene unterschiedliche innere Spannungen und Längen der Drähte 3 pro Zeiteinheit ausgeglichen werden.The bundle of wires 3 is then fed to the guide means 6. In the present case, the guide means 6 is designed as a guide roller. When leaving the guide means 6, the bundle is unfolded. The individual wires 3 are fed to the respectively associated, fixedly arranged dancer storage device 7 and further in an approximately parallel arrangement next to one another via a laying 8 of a laying device, not shown, of the multi-wire coil 10 of a multi-wire winder 9. The dancer storage device 7 assigned to each wire 3 ensures that any different internal tensions and lengths of the wires 3 which may still be present are compensated for during the winding process of the multi-wire coil 10.

Eine weitere Ausführungsform der Wickeleinrichtung 1 ist in Fig. 11 dargestellt. Die Wickeleinrichtung 1 weist ebenfalls eine Drahtzieheinrichtung 11 auf. Die einzelnen von den stationären Abläufen 2 ablaufenden Drähte 3 durchlaufen einzeln die Drahtzieheinrichtung 11 mit ihren Ziehsteinen 40 und den Ziehscheiben 41. Anschließend laufen die einzelnen Drähte 3 über eine getrennt angetriebene und geregelte Ziehscheibe 42 und weiter über die jeweils zugehörige Tänzerspeichereinrichtung 7. Es ist möglich die Tänzerspeichereinrichtung 7 als Regeleinrichtung für die Ziehscheibe 42 einzusetzen. Die Drähte 3 werden einer gemeinsamen Abzugsscheibe 5a mit einer Andrückrolle 43 zugeführt. Die Drähte 3 umschlingen in einer oder mehreren Windungen die Abzugsscheibe 5a annähernd parallel nebeneinander. Anschließend werden die annähernd parallel nebeneinander angeordneten Drähte 3 als Bündel über die Verlegung 8 der Verlegeeinrichtung dem geregelten Mehrdrahtwickler 9 zugeführt und dort auf die Mehrdrahtspule 10 aufgewikkelt. Dabei weisen durch die Vorbehandlung die Drähte 3 gleiche Drahtlängen auf. Es ist auch möglich eine derartige Wikkeleinrichtung 1 ohne eine Drahtzieheinrichtung 11 einzusetzen.Another embodiment of the winding device 1 is shown in FIG. 11. The winding device 1 also has a wire drawing device 11. The individual wires 3 running from the stationary processes 2 individually pass through the wire drawing device 11 with their drawing dies 40 and the drawing disks 41. The individual wires 3 then run via a separately driven and controlled drawing disk 42 and further via the respective associated dancer storage device 7. It is possible to use the dancer storage device 7 as a control device for the drawing disk 42. The wires 3 are fed to a common take-off wheel 5a with a pressure roller 43. In one or more turns, the wires 3 loop around the take-off disk 5a approximately parallel to one another. Subsequently, the wires 3, which are arranged approximately parallel to one another, are fed as a bundle to the regulated multi-wire winder 9 via the laying 8 of the laying device and are wound there onto the multi-wire coil 10. Due to the pretreatment, the wires 3 have the same wire lengths. It is also possible to use such a winding device 1 without a wire drawing device 11.

Die Anordnung der Andrückrolle 43 an der Abzugsscheibe 5a ist erforderlich um ein locker werden des Bündels von Drähten 3 auf der Abzugsscheibe 5a zu verhindern und somit einen für alle Drähte 3 gleichmäßigen Drahtzug zu gewährleisten.The arrangement of the pressure roller 43 on the take-off disk 5a is necessary in order to prevent the bundle of wires 3 from becoming loose on the take-off disk 5a and thus to ensure a uniform wire pull for all wires 3.

In Fig. 3 ist eine Ausführungsform einer Verseileinrichtung 12 der Vorrichtung zum gleichzeitigen Bewickeln der Mehrdrahtspule 10 mit mehreren Drähten 3 und/oder dem gleichzeitigen Abwickeln der Drähte 3 von der derart bewickelten Mehrdrahtspule 10 für die nachfolgende Verseilung derselben gezeigt. Die Verseileinrichtung 12 weist eine Doppelschlagverseilmaschine 12a nach dem Prinzip "in-out", einen Doppelscheibenabzug 13, eine oder mehrere in Ablaufrichtung der Drahtlitze 14 nacheinander angeordnete Überdreheinrichtungen 15 und Nachformeinrichtungen 16 sowie eine geregelte Aufwikkeleinrichtung 17 auf.FIG. 3 shows an embodiment of a stranding device 12 of the device for simultaneously winding the multi-wire coil 10 with a plurality of wires 3 and / or simultaneously unwinding the wires 3 from the multi-wire coil 10 thus wound for the subsequent stranding thereof. The stranding device 12 has a double-twist stranding machine 12a according to the "in-out" principle, a double-disk take-off 13, one or more over-twisting devices 15 and post-forming devices 16 arranged one after the other in the direction of the wire strand 14, and a regulated winding device 17.

Wie in Fig. 3 gezeigt, weist die Doppelschlagverseilmaschine 12a ein rotierendes System mit einem nicht mitdrehenden Spulenträger 19 auf. Die mit dem Bündel, von annähernd parallel nebeneinander angeordneten Drähten 3 bewickelte Mehrdrahtspule 10 ist in dem Spulenträger 19, innerhalb des rotierenden Systems, angeordnet. In dem Spulenträger 19 können aber auch mehrere Mehrdrahtspulen 10 und/oder Einzeldrahtspulen angeordnet sein.As shown in FIG. 3, the double-twist stranding machine 12a has a rotating system with a non-rotating bobbin 19. The one with the bundle of approximately parallel juxtaposed wires 3 wound multi-wire coil 10 is arranged in the bobbin 19, within the rotating system. However, a plurality of multi-wire coils 10 and / or single-wire coils can also be arranged in the coil carrier 19.

Der Spulenträger 19 ist über endseitige Drehzapfen 19a; 19b, auf der, die Drehachse bildende Mittelachse der Doppelschlagverseilmaschine 12a gelagert. Aufgrund seines Eigengewichtes dreht der Spulenträger 19, wie bereits dargelegt, beim Verseilvorgang nicht mit. Die endseitigen Drehzapfen 19a; 19b können hohl ausgebildet sein.The coil carrier 19 is via end pivot 19a; 19b, on the central axis of the double twist twisting machine 12a forming the axis of rotation. Due to its own weight, the bobbin 19 does not rotate during the stranding process, as already explained. The end pivot 19a; 19b can be hollow.

Es können weitere Ablaufspulen 10' in Form von Mehr- oder Einzeldrahtspulen vor dem Spulenträger 19 angeordnet sein. Von den Ablaufspulen 10' werden weitere Drähte und/oder gegebenenfalls der Kerndraht 3' der herzustellenden Drahtlitze 14 abgezogen. Dieser Kerndraht 3' kann ebenfalls eine aus mehreren Einzeldrähten bestehende Kernlitze sein. Der Kerndraht 3' läuft entlang der Mittelachse M zu dem Drehzapfen 19a und über eine Umlenkrolle 20a zu einem Führungselement 21a. Das Führungselement 21a ist ein Bestandteil des Flyers 22a, der im Bereich des vorderen Endes des Spulenträgers 19 angeordnet ist. Von dort läuft der Kerndraht 3' in einer freien Flugkurve zu einem Führungselement 21b eines im Bereich des hinteren Endes des Spulenträgers 19 angeordneten Flyers 22b. Über eine dem Drehzapfen 19b zugeordnete Umlenkrolle 20b wird der Kerndraht 3' in den Bereich der Mehrdrahtspule 10 geführt.Further pay-off coils 10 ′ in the form of multi-wire or single-wire coils can be arranged in front of the bobbin holder 19. Further wires and / or, if appropriate, the core wire 3 'of the stranded wire 14 to be produced are drawn off from the supply coils 10'. This core wire 3 'can also be a core strand consisting of several individual wires. The core wire 3 'runs along the central axis M to the pivot 19a and via a deflection roller 20a to a guide element 21a. The guide element 21a is a component of the flyer 22a, which is arranged in the region of the front end of the coil carrier 19. From there, the core wire 3 'runs in a free flight curve to a guide element 21b of a flyer 22b arranged in the region of the rear end of the coil carrier 19. The core wire 3 ′ is guided into the area of the multi-wire coil 10 via a deflection roller 20b assigned to the pivot pin 19b.

Die Führungselemente 21a; 21b können als Führungsrollen oder Führungsnippel ausgeführt sein. Eine konische Umlenkrolle 23 ist auf, oder in dem vorderen Drehzapfen 19a im Bereich der Mittelachse M gelagert. Die Längsachse der Umlenkrolle 23 verläuft im wesentlichen senkrecht zur Mittelachse M. Die Umlenkrolle 23 bildet einen ersten Umlenkpunkt für das von der Mehrdrahtspule 10 und gegebenenfalls weiteren Ablaufspulen abgezogene Verseilgut. Das Verseilgut besteht aus den Drähten 3 und gegebenenfalls dem Kerndraht 3'.The guide elements 21a; 21b can be designed as guide rollers or guide nipples. A conical deflection roller 23 is mounted on or in the front pivot 19a in the area of the central axis M. The longitudinal axis of the deflection roller 23 extends essentially perpendicular to the central axis M. The deflection roller 23 forms a first deflection point for that of the multi-wire spool 10 and, if appropriate, further payout spools stripped stranded material. The stranded material consists of the wires 3 and possibly the core wire 3 '.

Wie in Fig. 4 gezeigt, läuft das Verseilgut auf dem größten Durchmesserabschnitt der konischen Umlenkrolle 23 auf. Das Verseilgut gleitet während der Umlenkung, unter Eigendrehung auf dem Mantel der Umlenkrolle 23, zum schmaleren Endteil hin ab. Hierdurch erfährt das Verseilgut eine vollständige Verseilung und bildet eine Drahtlitze 14. Der erste und zweite Verseilschlag werden dadurch in einem Verseilpunkt 24 (Fig. 5) vereinigt.As shown in FIG. 4, the stranded material runs onto the largest diameter section of the conical deflection roller 23. The stranded material slides off during the deflection, with its own rotation on the jacket of the deflection roller 23, towards the narrower end part. As a result, the stranded material undergoes a complete stranding and forms a wire strand 14. The first and second stranding twists are thereby combined in a stranding point 24 (FIG. 5).

Wie in Fig. 3 und Fig. 5 gezeigt, werden die als Bündel von der Mehrdrahtspule 10 abgezogenen Drähte 3 und gegebenenfalls auch die Drähte weiterer Ablaufspulen, hier der Kerndraht 3' der Ablaufspule 10', über ein Rollensystem 25 geführt. Das Rollensystem 25 ist in Form eines Flaschenzuges mit einer Betätigungsrolle 25a und einer Drahtzugbremse 26 ausgebildet. Alle von der Mehrdrahtspule 10 ablaufenden Drähte 3 verlaufen dann in einem geringen seitlichen Abstand zur Mittelachse M zu dem Verseilpunkt 24 und danach als Drahtlitze 14 entlang der Mittelachse M durch den hohlen Drehzapfen 19a hindurch zum breiteren Endteil der konischen Umlenkrolle 23.As shown in FIGS. 3 and 5, the wires 3 drawn off as a bundle from the multi-wire spool 10 and optionally also the wires of further payout spools, here the core wire 3 'of the payout spool 10', are guided over a roller system 25. The roller system 25 is designed in the form of a pulley block with an actuating roller 25a and a wire brake 26. All of the wires 3 running from the multi-wire coil 10 then run at a small lateral distance from the central axis M to the stranding point 24 and then as a stranded wire 14 along the central axis M through the hollow pivot 19a to the wider end part of the conical deflection roller 23.

Der Abschnitt zwischen der Mehrdrahtspule 10 und der Umlenkrolle 23 weist wie in Fig. 3 und Fig. 5 gezeigt, in Ablaufrichtung des Verseilgutes das oben beschriebene Rollensystem 25 auf. Entsprechend der Anzahl der ablaufenden Drähte 3 sind mit einstellbaren Kräften belastete Tänzerspeichereinrichtungen 7' angeordnet. Weiterhin ist gegebenenfalls eine Vorformeinrichtung in einer Legescheibe 27 sowie der gemeinsamen Verseilpunkt 24 für den ersten und zweiten Verseilschlag vorgesehen. Außerdem kann eine Dralliereinrichtung 28 angeordnet sein.The section between the multi-wire coil 10 and the deflection roller 23 has, as shown in FIGS. 3 and 5, the above-described roller system 25 in the direction of the stranded material. Dancer storage devices 7 'loaded with adjustable forces are arranged in accordance with the number of running wires 3. Furthermore, a preforming device is optionally provided in a washer 27 and the common stranding point 24 for the first and second stranding twist. A swirl device 28 can also be arranged.

Während der Verseilung wird das Bündel der annähernd parallel nebeneinander angeordneten Drähte 3 mit konstanter Spannung von der Mehrdrahtspule 10 abgezogen. Das Bündel wird über das Rollensystem 25 geführt und in einzelne Drähte 3 auseinandergefacht. Die Drähte 3 werden jeweils einer eigenen zugehörigen, ortsfest am Spulenträger 19 angeordneten Tänzerspeichereinrichtung 7' zugeführt. Mittels der Tänzerspeichereinrichtung 7' erfolgt pro Zeiteinheit ein spannungs- und längenausgleichender Abwickelvorgang der Drähte 3, der sich vorteilhaft auf die Qualität der herzustellenden Drahtlitze 14 auswirkt.During the stranding, the bundle becomes approximately parallel wires 3 arranged next to one another are drawn off from the multi-wire coil 10 at constant voltage. The bundle is guided over the roller system 25 and separated into individual wires 3. The wires 3 are each fed to their own associated dancer storage device 7 'arranged fixedly on the coil carrier 19. By means of the dancer storage device 7 ', a tension and length-compensating unwinding process of the wires 3 takes place, which has an advantageous effect on the quality of the wire strand 14 to be produced.

In der Fig. 6 ist eine vorteilhafte Ausführungsform der Tänzerspeichereinrichtung 7; 7' näher dargestellt. Diese weist einen separat gelagerten und mit einstellbaren Kräften belasteten Hebelarm 29 mit einer Drahtführungsrolle 30 auf. Der Hebelarm 29 kann federbelastet sein. Es ist auch eine andere Belastung beispielsweise mit Gewichten oder pneumatisch möglich. In Fig. 5 wird der Einsatz der Tänzerspeichereinrichtung 7' in der Verseileinrichtung 12 gezeigt. In den Fig. 1, 2 und 11 ist die Tänzerspeichereinrichtung 7 in der Wikkeleinrichtung 1 angeordnet, wobei die Drahtführungsrolle 30 als Tänzerrolle eine vertikale Bewegung ausführt.6 shows an advantageous embodiment of the dancer storage device 7; 7 'shown in more detail. This has a separately mounted lever arm 29 loaded with adjustable forces and having a wire guide roller 30. The lever arm 29 can be spring-loaded. Another load, for example with weights or pneumatically, is also possible. 5 shows the use of the dancer storage device 7 'in the stranding device 12. 1, 2 and 11, the dancer storage device 7 is arranged in the winding device 1, the wire guide roller 30 executing a vertical movement as a dancer roller.

Die Vorformung der einzelnen Drähte 3 mittels der Vorformeinrichtung in der Legescheibe 27 ist bei bestimmten zu verarbeitenden Materialien, insbesondere bei HT- und Ultra-HT-Drähten, erforderlich, damit diese ihre Lage im Verseilverband erhalten. An sich bekannte und demzufolge nicht näher dargestellte Ausführungsformen von Vorformeinrichtungen sehen Vorformnippel oder auch Vorformrollen vor. Die vom Verseilpunkt 24 kommende, geometrisch fertige Drahtlitze 14 kann, in Abhängigkeit vom zu verarbeitenden Drahtmaterial, mittels der Dralliereinrichtung 28 (Fig. 5) überdreht werden. Damit erhält jeder der einzelnen Drähte 3 im Verseilverband die erforderliche Länge. Es ist in diesem Fall eine plastische Verformung zu verzeichnen. Die Dralliereinrichtung 28 dreht dabei in gleicher Richtung, jedoch mit einer höheren Drehgeschwindigkeit wie die Flyer 22a; 22b der Doppelschlagverseilmaschine 12a. Je nach gewünschtem Verseilaufbau hat sich eine 1,4 bis 1,95 fach höhere Drehgeschwindigkeit der Dralliereinrichtung 28 gegenüber den Flyern 22a; 22b als vorteilhaft erwiesen.The preforming of the individual wires 3 by means of the preforming device in the laying disk 27 is necessary for certain materials to be processed, in particular for HT and Ultra-HT wires, so that they are held in the stranded structure. Known and consequently not shown embodiments of preform devices provide preform nipples or preform rollers. The geometrically finished wire strand 14 coming from the stranding point 24 can, depending on the wire material to be processed, be overturned by means of the twisting device 28 (FIG. 5). This gives each of the individual wires 3 in the stranding the required length. In this case there is a plastic deformation. The twist device 28 rotates in the same direction, but at a higher rotational speed than the flyers 22a; 22b of the double twist stranding machine 12a. Depending on the desired stranding structure, the twisting device 28 has a 1.4 to 1.95 times higher rotational speed than the flyers 22a; 22b proved to be advantageous.

Die vom schmalen Endteil der Umlenkrolle 23 abgezogene, nunmehr in ihrer Struktur fertige Drahtlitze 14 läuft gemäß Fig. 3 zum Führungselement 31a des ersten Flyers 22a und von diesem in freier Flugkurve über das Führungselement 31b des zweiten Flyers 22b zu einer in dem Drehzapfen 19b quer zur Mittelachse M gelagerten Umlenkrolle 32. Die Führungselemente 31a; 31b können als Führungsrollen oder als Führungsnippel ausgeführt sein. Die beiden Flyer 22a; 22b werden gemeinsam über an sich bekannte Getriebe, beispielsweise Zahnriementriebe, von einem Antriebsmotor 33 synchron angetrieben. Dabei rotiert die an dem Drehzapfen 19a gelagerte konische Umlenkrolle 23 zusammen mit dem Flyer 22a um die Mittelachse M. In der Fig. 5 ist der Spulenträger 19 mit einer Mehrdrahtspule 10 sowie der jeweils zugehörigen Drahtzugbremse 26 und dem Rollensystem 25 näher gezeigt. Die Drahtzugbremse 26 ist als eine sogenannte tänzergesteuerte Bremse ausgeführt und weist einen zweiarmigen Schwenkhebel 26a auf. An dem einen Arm des Schwenkhebels ist die von den ablaufenden Drähten 3 umschlungene Betätigungsrolle 25a gelagert. An dem anderen Arm des Schwenkhebels greift ein Federelement 26b an. Der, die Betätigungsrolle 25a tragende Arm ist über ein Gestänge 26c mit einem mit Bremsbacken 35 versehenen Bremsband 34 verbunden. Der Bremsbelag des Bremsbandes 34 drückt gegen die Bremsfläche einer auf der Welle der Mehrdrahtspule 10 befestigten Bremsscheibe 36. Wie vorstehend beschrieben, ist der Drahtzugbremse 26 ein Rollensystem 25 in Form eines Flaschenzuges zugeordnet. Die auf dem Schwenkhebel 26a gelagerte Betätigungsrolle 25a ist gleichzeitig ein Bestandteil des Rollensystems 25. Über die Betätigungsrolle 25a werden die Drähte 3 dem Rollensystem 25 zugeführt und durchlaufen dieses in mehreren Windungen.The wire strand 14 drawn off from the narrow end part of the deflection roller 23 and now finished in its structure runs according to FIG. 3 to the guide element 31a of the first flyer 22a and from there in a free flight curve over the guide element 31b of the second flyer 22b to one in the pivot 19b transversely to Center axis M mounted deflection roller 32. The guide elements 31a; 31b can be designed as guide rollers or as guide nipples. The two flyers 22a; 22b are driven synchronously by a drive motor 33 via gearboxes known per se, for example toothed belt drives. The conical deflection roller 23 mounted on the pivot 19a rotates together with the flyer 22a about the central axis M. In FIG. 5, the coil carrier 19 with a multi-wire coil 10 and the associated wire pull brake 26 and the roller system 25 are shown in more detail. The wire pull brake 26 is designed as a so-called dancer-controlled brake and has a two-armed pivot lever 26a. The actuating roller 25a, which is wrapped around by the running wires 3, is mounted on one arm of the pivoting lever. A spring element 26b acts on the other arm of the pivoting lever. The arm carrying the actuating roller 25a is connected via a linkage 26c to a brake band 34 provided with brake shoes 35. The brake lining of the brake band 34 presses against the braking surface of a brake disk 36 fastened on the shaft of the multi-wire coil 10. As described above, the wire tension brake 26 is assigned a roller system 25 in the form of a pulley block. The actuating roller 25a mounted on the swivel lever 26a is at the same time a component of the roller system 25 Wires 3 fed to the roller system 25 and pass through it in several turns.

Durch die Führung der Drähte 3 über das Rollensystem 25 in mehreren Windungen wird erreicht, daß bei großen Spulenmassen und damit großen Abzugskräften die Drahtzugkräfte über die gesamte Spulenfüllung gering und konstant gehalten werden können. Damit sind auch sehr dünne Drähte 3 zu verarbeiten.By guiding the wires 3 over the roller system 25 in several turns it is achieved that the wire tensile forces can be kept low and constant over the entire coil filling with large coil masses and thus large withdrawal forces. This means that very thin wires 3 can also be processed.

Die bereits bei ihrem Einlauf in den ersten Flyer 22a fertig strukturierte Drahtlitze 14 bleibt in ihrer Struktur im Bereich der freien Flugkurve zwischen den beiden Flyern 22a; 22b erhalten. Die Drahtlitze 14 wird beim Verlassen der Doppelschlagverseilmaschine 12a über die um die Mittelachse M umlaufende Umlenkrolle 32 dem Doppelscheibenabzug 13 zugeführt. In Fig. 7 ist der Doppelscheibenabzug 13 näher dargestellt. Er weist zwei, achsparallel im Abstand zueinander angeordnete Rollen 13a; 13b auf. Dabei kann die Rolle 13a mit Umfangsrillen 13c versehen sein, während die Rolle 13b eine Stufe 13d aufweist. Die Drahtlitze 14 läuft in mehreren geordneten Schlingen um die beiden Rollen 13a; 13b, wobei die Stufe 13d einen Sprung von einem kleineren zu einem größeren Rollendurchmesser verursacht. Hierdurch erfolgt ein definierter Zugkraftanstieg, durch den im Zusammenwirken mit der Überdrehung 15 Torsionsspannungen in der Drahtlitze 14 abgebaut werden.The structure of the wire strand 14 which is already structured when it enters the first flyer 22a remains in the area of the free flight curve between the two flyers 22a; 22b received. The wire strand 14 is fed to the double-disc take-off 13 when it leaves the double-twist stranding machine 12a via the deflecting roller 32 rotating around the central axis M. In Fig. 7, the double disc trigger 13 is shown in more detail. It has two rollers 13a; 13b. The roller 13a can be provided with circumferential grooves 13c, while the roller 13b has a step 13d. The wire strand 14 runs in a number of ordered loops around the two rollers 13a; 13b, step 13d causing a jump from a smaller to a larger roll diameter. This results in a defined increase in tensile force, through which 15 torsional stresses in the wire strand 14 are reduced in cooperation with the overturning.

Zum weiteren vollständigen Abbau von inneren Spannungen und zur Erhaltung des Verseilverbandes der Drahtlitze 14 ist im Bereich des Doppelscheibenabzuges 13, wie in Fig. 3 gezeigt, eine Nachformeinrichtung 16 hinter der Überdreheinrichtung 15 angeordnet. Die Überdreheinrichtung 15 ihrerseits weist eine zu den Flyern 22a; 22b der Doppelschlagverseilmaschine 12a entgegengesetzte Drehrichtung auf. Je nach gewünschtem Verseilaufbau dreht die Überdreheinrichtung 15 mit der 0,3 bis 1,0 fachen Drehgeschwindigkeit der Flyer 22a; 22b. Die Überdreheinrichtung 15 wird durch einen nicht näher dargestellten Antrieb getrennt von der Doppelschlagverseilmaschine 12a angetrieben. Die Regelung dieses Antriebes erfolgt in Abhängigkeit vom dargestellten Antriebsmotor 33 (Hauptantrieb) für die Doppelschlagverseilmaschine 12a und dem Doppelscheibenabzug 13 durch eine nicht näher dargestellte Regel- und Steuereinrichtung. Die Regelung der Drehrichtung und Drehgeschwindigkeit der Überdreheinrichtung 15 erfolgt ebenfalls über die Regel- und Steuereinrichtung.To further completely reduce internal tensions and to maintain the stranding of the wire strand 14, a post-forming device 16 is arranged behind the overturning device 15 in the region of the double-disk take-off 13, as shown in FIG. 3. The overturning device 15 in turn has one towards the flyers 22a; 22b of the double twist stranding machine 12a in the opposite direction of rotation. Depending on the desired stranding structure, the overturning device 15 rotates at a speed of 0.3 to 1.0 times that of the flyers 22a; 22b. The overturning device 15 is by a not shown Drive driven separately from the double twist stranding machine 12a. This drive is controlled as a function of the drive motor 33 (main drive) shown for the double-twist twisting machine 12a and the double-disk take-off 13 by a regulating and control device (not shown in more detail). The direction of rotation and the speed of rotation of the overturning device 15 are likewise regulated via the regulating and control device.

Die Drahtlitze 14 wird über Umlenkrollen 37 einer oder mehreren Nachformeinrichtungen 16 zugeführt, die mindestens eine Reihe von hintereinander, mit gegenseitiger Versetzung angeordnete Richtrollen aufweisen. Die gegenseitige Versetzung der Richtrollen kann nach den jeweiligen Produkt- und Betriebsbedingungen eingestellt werden kann. Die Drahtlitze 14 läuft dabei in einer wellenförmigen Bahn über die Richtrollen, und durch die dabei entstehenden Biege- und Walkwirkungen erfolgt ein Spannungsabbau sowie Lagekorrekturen der Drähte 3; 3' der Drahtlitze 14. Anschließend wird die Drahtlitze 15 über eine weitere Umlenkrolle 37 und die Rollen 13a; 13b des Doppelscheibenabzuges 13 sowie einer Verlegeeinrichtung 18 der geregelten und getrennt angetriebenen Aufwickeleinrichtung 17 zugeführt. Die von der Doppelschlagverseilmaschine 12a kommende Drahtlitze 14 wird in Pfeilrichtung, entlang den Führungsabschnitten a bis i geführt.The wire strand 14 is fed via deflection rollers 37 to one or more post-forming devices 16 which have at least one row of straightening rollers arranged one behind the other with mutual offset. The mutual relocation of the straightening rolls can be adjusted according to the respective product and operating conditions. The wire strand 14 runs in a wave-shaped path over the straightening rollers, and the resulting bending and flexing effects reduce tension and correct the position of the wires 3; 3 'of the wire strand 14. The wire strand 15 is then passed over a further deflection roller 37 and the rollers 13a; 13b of the double-disc take-off 13 and a laying device 18 of the controlled and separately driven winding device 17. The stranded wire 14 coming from the double twist stranding machine 12a is guided in the direction of the arrow, along the guide sections a to i.

Der Kerndraht 3' wird, wie anhand der Fig. 3 beschrieben, von einer außerhalb des Spulenträgers 19 angeordneten Ablaufspule 10' abgezogen. Es ist aber auch möglich den Kerndraht 3', in an sich bekannter Weise, von einer weiteren im Spulenträger 19 angeordneten Ablaufspule abzuziehen.As described with reference to FIG. 3, the core wire 3 'is drawn off from a payout spool 10' arranged outside the spool carrier 19. However, it is also possible to pull off the core wire 3 ', in a manner known per se, from a further payout spool arranged in the spool carrier 19.

Weiterhin können, wie in Fig. 8 dargestellt, sämtliche Umlenk- und Führungsrollen, über die die Drähte 3 in annähernd paralleler Anordnung nebeneinander geführt werden, eine oder mehrere Führungsrillen 38 mit flachem Rollenquerschnitt aufweisen. Die Führungsrillen 38 gewährleisten eine annähernd geordnete parallele Führung der Drähte 3 nebeneinander und verhindern insbesondere Schlaufenbildungen, die sich erheblich nachteilig, insbesondere bei der Verseilung, auswirken würden.Furthermore, as shown in FIG. 8, all deflection and guide rollers, over which the wires 3 are guided next to one another in an approximately parallel arrangement, can have one or more guide grooves 38 with a flat roller cross section. The guide grooves 38 ensure approximately orderly parallel guidance of the wires 3 next to each other and in particular prevent loop formation, which would have a considerably disadvantageous effect, in particular when stranding.

In der Fig. 9 ist eine weitere Ausführungsform der zu der Vorrichtung gehörenden Verseileinrichtung 12 gezeigt. Bei der Verseileinrichtung 12 ist die Doppelschlagverseilmaschine 12a nach dem Prinzip "in-out" durch eine Doppelschlagverseilmaschine 12b nach dem Prinzip "out-in" ersetzt. Folglich sind die eingesetzten Mehrdrahtspulen 10 nicht innerhalb, sondern außerhalb des rotierenden Systems der Doppelschlagverseilmaschine 12b angeordnet.FIG. 9 shows a further embodiment of the stranding device 12 belonging to the device. In the stranding device 12, the double-twist stranding machine 12a according to the "in-out" principle is replaced by a double-twist stranding machine 12b according to the "out-in" principle. As a result, the multi-wire coils 10 used are not arranged inside but outside the rotating system of the double-twist twisting machine 12b.

Hierbei sind die Mehrdrahtspulen 10 jeweils mit einem Bündel parallel zueinander angeordneter Drähte 3 bewickelt und in einem außerhalb der Doppelschlagverseilmaschine 12b ortsfest angeordneten Spulenträger 19 gelagert. Entsprechend der Fig. 9 sind in dem Spulenträger 19 drei Mehrdrahtspulen 10 angeordnet, von denen jeweils drei Drähte 3 abgezogen werden. Den Mehrdrahtspulen 10 ist eine weitere Ablaufspule 10' zugeordnet. Von der Ablaufspule 10' kann ein Kerndraht 3' oder eine Kernlitze, die beispielsweise aus drei Einzeldrähten besteht, abgezogen werden.In this case, the multi-wire coils 10 are each wound with a bundle of wires 3 arranged parallel to one another and are mounted in a coil carrier 19 which is arranged in a stationary manner outside the double-twist twisting machine 12b. According to FIG. 9, three multi-wire coils 10 are arranged in the coil carrier 19, from which three wires 3 are pulled off. Another multi-wire coil 10 'is assigned to the multi-wire coils 10. A core wire 3 'or a core strand, which consists, for example, of three individual wires, can be drawn off from the winding spool 10'.

Diese Anlagenkonfiguration ist geeignet zur Herstellung von Drahtlitzen 14 der Ausbildung 1+9 oder 3+9. Bei der Ausbildung 1+9 besteht die Drahtlitze 14 aus einem Kerndraht 3' und neun Drähten 3. Während bei der Ausbildung 3+9 die Drahtlitze 14 aus einer Kernlitze mit drei Einzeldrähten sowie neun Drähten 3 gebildet wird.This system configuration is suitable for the production of wire strands 14 of the design 1 + 9 or 3 + 9. In the training 1 + 9, the wire strand 14 consists of a core wire 3 'and nine wires 3. While in the training 3 + 9, the wire strand 14 is formed from a core strand with three individual wires and nine wires 3.

Zum Verseilen werden die einzelnen Drähte 3 und der Kerndraht 3' mit gleichbleibender Zugkraft abgezogen. In Drahtlaufrichtung wird das Bündel annähernd parallel nebeneinander angeordneter Drähte 3, von der jeweiligen Mehrdrahtspule 10 kommend, über das Rollensystem 25 mit der Drahtzugbremse 26 geführt. Anschließend wird jeder einzelne Draht 3 über eine eigene ortsfest am oder hinter dem Spulenträger 19 angeordnete Tänzerspeicherinrichtung 7' geführt. Im Anschluß daran werden die Drähte 3 über die Legescheibe 27 dem Verseilpunkt 24 zugeführt, wobei die Drähte 3 eine Vorformeinrichtung durchlaufen können. Der Kerndraht 3' wird seinerseits ebenfalls über ein zugehöriges Rollensystem 25 mit einer Drahtzugbremse 26 geführt, läuft jedoch dann direkt über die Legescheibe 27 zum Verseilpunkt 24. Das Verseilgut, bestehend aus Drähten 3 und dem Kerndraht 3', wird nachfolgend dem rotierenden System der Doppelschlagverseilmaschine 12b zugeführt. Der eigentliche Verseilvorgang erfolgt derart, daß das Verseilgut im ersten Umlenkpunkt über eine im ersten Drehzapfen 19a angeordnete und mitdrehende Umlenkrolle 20a sowie weiter über ein Führungselement 31a des zugehörigen Flyers 22a geführt wird. In freier Flugkurve wird das Führungselement 31b des synchron drehenden zweiten Flyers 22b erreicht und von dort, der im zweiten Drehzapfen 19b angeordneten sowie mit-drehenden konischen Umlenkrolle 23 zugeführt. Auf der konischen Umlenkrolle 23 läuft das Verseilgut auf dem größten Durchmesserabschnitt auf. Das Verseilgut gleitet während der Umlenkung, unter Eigendrehung auf dem Mantel der Umlenkrolle 23, zum schamleren Endteil hin ab. Hierdurch erfährt das Verseilgut eine vollständige Verseilung und bildet die Drahtlitze 14. Der erste und zweite Verseilschlag sind dadurch in dem Verseilpunkt 24 vereinigt. Von der konischen Umlenkrolle 23 kommend, wird die Drahtlitze 14 über einen Doppelscheibenabzug 13, eine nachfolgende Überdreheinrichtung 15 und eine Nachformeinrichtung 16 der geregelten Aufwickeleinrichtung 17 mit der Verlegeeinrichtung 18 zugeführt. Der Doppelscheibenabzug 13, die Überdreheinrichtung 15, die Nachformeinrichtung 16 und die Aufwickeleinrichtung 17 mit der Verlegeinrichtung 18 sind, in an sich bekannter Weise, in einem Spulenträger 39 ortsfest angeordnet. Der Spulenträger 39 ist zwar auf dem endseitigen Drehzapfen 19a; 19b drehbar gelagert, jedoch dreht er auf Grund seines Eigengewichtes beim Verseilvorgang nicht mit.For stranding, the individual wires 3 and the core wire 3 'are pulled off with constant tensile force. In the wire running direction, the bundle of wires 3 arranged approximately parallel to one another, from the respective multi-wire coil 10 coming, guided over the roller system 25 with the wire pull brake 26. Each individual wire 3 is then guided over its own dancer storage device 7 'which is arranged in a fixed position on or behind the coil carrier 19. Following this, the wires 3 are fed to the stranding point 24 via the washer 27, wherein the wires 3 can pass through a preforming device. The core wire 3 'is in turn also guided via an associated roller system 25 with a wire pull brake 26, but then runs directly over the laying disc 27 to the stranding point 24. The stranded material, consisting of wires 3 and the core wire 3', subsequently becomes the rotating system of the double-strand stranding machine 12b supplied. The actual stranding process takes place in such a way that the stranded material is guided in the first deflection point via a deflecting roller 20a which is arranged in the first pivot 19a and rotates along with it and further over a guide element 31a of the associated flyer 22a. The guide element 31b of the synchronously rotating second flyer 22b is reached in a free flight curve and from there it is fed to the conical deflection roller 23 which is arranged in the second pivot 19b and rotates with it. The stranded material runs onto the largest diameter section on the conical deflection roller 23. The stranded material slides during the deflection, with its own rotation on the jacket of the deflecting roller 23, towards the smaller end part. As a result, the stranded material undergoes a complete stranding and forms the stranded wire 14. The first and second stranding twists are thereby combined in the stranding point 24. Coming from the conical deflection roller 23, the stranded wire 14 is fed to the controlled winding device 17 with the laying device 18 via a double-disk take-off 13, a subsequent overturning device 15 and a post-forming device 16. The double-disk take-off 13, the overturning device 15, the post-forming device 16 and the winding device 17 with the laying device 18 are, in a manner known per se, arranged in a stationary manner in a bobbin 39. The coil carrier 39 is indeed on the end pivot 19a; 19b rotatably, however due to its own weight, it does not turn during the stranding process.

Wie in Fig.9 gezeigt, besteht weiterhin die Möglichkeit, zwischen dem Verseilpunkt 24 und der ersten Umlenkrolle 20a, außerhalb des rotierenden Systems der Doppelschlagverseilmaschine 12b, eine Dralliereinrichtung 28 anzuordnen. Weitere Ausführungen zu den vorerwähnten Einrichtungen erübrigen sich, da diese in ihrer näheren Ausgestaltung und Funktionsweise den gleichlautenden und gleichbezeichneten und bereits zur Doppelschlagverseilmaschine 12a beschriebenen Einrichtungen entsprechen.As shown in FIG. 9, there is also the possibility of arranging a twisting device 28 between the stranding point 24 and the first deflecting roller 20a, outside the rotating system of the double-twist stranding machine 12b. Further explanations on the above-mentioned devices are superfluous, since their detailed design and mode of operation correspond to the devices of the same name and the same designation and already described for the double-twist twisting machine 12a.

In den Figuren 10a bis 10g sind Konfigurationen der Verseileinrichtung 12 mit Draht- und Litzenlauf gezeigt. Der Umfang der Erfindung wird jedoch nicht auf diese Beispiele beschränkt.FIGS. 10a to 10g show configurations of the stranding device 12 with a wire and strand run. However, the scope of the invention is not limited to these examples.

Im Anschluß daran werden die einzelnen Drähte 3 über ihre jeweilige Tänzerspeichereinrichtung 7' geführt und verseilt. Nachdem die in ihrer Struktur fertige Drahtlitze 14 zum Abbau ihrer inneren Spannungen einem definierten Zugkraftanstieg und einem oder mehreren Überdreh- und Nachformvorgängen, wie bereits beschrieben, unterworfen wird, wird die fertige Drahtlitze 14 mit gleichbleibender Aufwikkelkraft der geregelten Aufwickeleinrichtung 17 zugeführt.According to FIG. 10a, a multi-wire coil 10 is arranged in the rotating system of a double-twist twisting machine 12a, which according to the programs 1x2; 1x3; 1x4 or 2 + 2 is wound with a bundle of two to four individual wires 3 arranged parallel to one another. The bundle of wires 3 is pulled off and unfolded with constant tensile force. Subsequently, the individual wires 3 are guided and stranded over their respective dancer storage device 7 '. After the wire strand 14, which is finished in its structure, is subjected to a defined increase in tensile force and one or more overturning and post-forming processes, as already described, in order to reduce its internal stresses, the finished wire strand 14 is fed to the controlled winding device 17 with a constant winding force.
