Description

Die vorliegende Erfindung betrifft ein Verfahren zum Verdrillen von mindestens zwei Einzelleitungen und eine Verdrill vorrichtung zu diesem Zwecke.The present invention relates to a method for twisting of at least two individual lines and a twisting device for this purpose.

Ein Verfahren zum Verdrillen und eine Verdrillvorrichtung sind aus DE-U-1838249 bekannt.A twisting method and a twisting device are known from DE-U-1838249.

Verdrillte Leitungen finden vielfach Anwendung für die unterschiedlichsten Zwecke, bei denen eine entsprechende elektromagnetische Verträglichkeit (EMV) gewünscht ist. Ein Einsatzgebiet ist die Verwendung von solchen Leitungen im Automobilbau für z.B. Lautsprecher- oder Airbagleitungen. Bisher sind die verdrillten Leitungen immer vom Leitungshersteller endlos verdrillt und in Fässern aufgewickelt verkauft worden. Bei solchen endlosen Verdrillvorgängen sind die Kabeltrommeln mit den "endlosen" Einzelleitungen am Verdrillkopf drehbar befestigt und rotieren mit diesem um die Verdrillachse. Die verdrillten Leitungen werden dann für den entsprechenden Einsatzzweck auf Länge geschnitten, die Enden teilweise wieder aufgedrillt und mit entsprechenden Einrichtungen, wie z.B. Kontaktanschlüssen, Anschlagteilen, Einzeladerabdichtungen usw. bestückt. Diese Vorgänge sind sehr arbeits- und deshalb kostenintensiv. Des weiteren muß der Lagerbestand von verdrillten Leitungen relativ hoch sein, da diese mit verschiedenen Durchmessern, Verdrillsteigungen, Anzahl von Einzelleitungen, verschiedenen Farbkombinationen der Einzelleitungen usw. für die entsprechenden Einsatzzwecke hergestellt werden.Twisted cables are used in many different ways Purposes where a corresponding electromagnetic Compatibility (EMC) is desired. An area of application is the use of such cables in automotive engineering for e.g. Loudspeaker or airbag lines. So far they are twisted lines are always twisted by the cable manufacturer and sold in barrels. In such Endless twisting processes are the cable drums with the "Endless" individual cables rotatably attached to the twisting head and rotate with it around the twist axis. The twisted Lines are then on for the appropriate purpose Cut length, the ends partially re-twisted and with appropriate facilities, such as Contact connections, Stop parts, single wire seals, etc. equipped. This Operations are very labor intensive and therefore costly. Of further, the inventory of twisted wires must be relative be high because these have different diameters, twist pitches, Number of individual lines, different color combinations of the individual lines etc. for the corresponding purposes getting produced.

Es ist nunmehr die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Verdrillen von Einzelleitungen bereitzustellen, das ein Herstellen von verdrillten Leitungen für den Kabelkonfektionär in Bezug auf Arbeitsaufwand, Herstellungs- und Lagerkosten attraktiver gestaltet.It is now the object of the present invention, a method to twist single lines to provide the a manufacture of twisted lines for the cable assembler in terms of labor, manufacturing and storage costs more attractive.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den folgenden Schritten gelöst:

  • Einspannen der einen Leitungsenden von auf eine bestimmte Länge abgelängten Einzelleitungen in jeweils eine separate, im wesentlichen parallel zu einer Verdrillachse drehbaren Entdrillspannaufnahme;
  • Einspannen der anderen Leitungsenden der Einzelleitungen im jeweils separaten Verdrillspannaufnahmen, die gemeinsam um die Verdrillachse drehbar angeordnet sind;
  • Anordnen eines Drillschiffs zwischen den im wesentlichen gespannten Leitungen; und
  • Drehen der Verdrillspannaufnahme gemeinsam um die Verdrillachse und gleichläufiges Drehen der Entdrillspannaufnahmen jeweils um die Leitungsachse der jeweiligen Leitungen.
  • According to the invention, this object is achieved by a method with the following steps:
  • Clamping the one line ends of individual lines cut to a certain length into a separate, untwisting, twist-off receptacle that can be rotated essentially parallel to a twisting axis;
  • Clamping the other line ends of the individual lines in the separate twisting clamping receptacles, which are arranged together rotatable about the twisting axis;
  • Placing a drill ship between the substantially tensioned lines; and
  • Rotating the twist clamping fixture together around the twisting axis and rotating the twisting clamping fixtures in each case around the line axis of the respective lines.
  • Der enorme Vorteil dieses Verfahrens besteht darin, daß Einzelleitungen vor der Verdrillung auf eine bestimmte Länge abgelängt, eventuell abisoliert und mit verschiedenen Bauelementen versehen werden können. Die eventuell mit Anbauteilen versehenen Enden der Leitungen werden dann in die entsprechenden Spannaufnahmen eingelegt und festgeklemmt, wobei bevorzugt jeder Spannaufnahme ein Leitungsende zugeordnet ist. Die Verdrillspannaufnahmen und das Drillschiff sorgen dann für die Verdrillung der Einzelleitungen, während die Entdrillspannaufnahmen im wesentlichen parallel zur Verdrillachse angeordnet verbleiben können. Da durch die gemeinsame Drehbewegung der Verdrillspannaufnahmen die Einzelleitungen bei jeder Umdrehung um die Verdrillachse jeweils auch um ihre Achse gedreht werden, sorgen die Entdrillspannaufnahmen für eine entsprechend gleichläufige Drehbewegung jeder einzelnen Einzelleitung, damit diese sich nicht in sich verdrehen.The enormous advantage of this method is that single lines cut to a certain length before twisting, possibly stripped and with various components can be provided. The possibly provided with attachments Ends of the lines are then in the appropriate Clamping shots inserted and clamped, preferably everyone Clamping receptacle is assigned to one line end. The twist clamps and the drill ship will take care of that Twisting of the individual lines while the untwisting tension recordings arranged essentially parallel to the twist axis can remain. Because of the common rotational movement of the Twist tension recordings of the individual cables with every revolution about the twisting axis are also rotated about their axis, the untwisting tension recordings ensure a corresponding co-rotating movement of each individual line, so they don't twist.

    Durch das erfindungsgemäße Verfahren lassen sich die Materialbestände der Lager verringern, da nicht mehr alle Kombinationen zwischen Leitungsfarbe und -querschnitt auf Lager gehalten werden müssen. Die benötigten Leitungspaarungen können nun entsprechend den Wünschen des Kabelkonfektionärs aus Standardleitungen hergestellt werden. Im Gegensatz zur Verarbeitung von herkömmlich verdrillten Leitungen entstehen keine Probleme beim Entdrillen, Glätten, Abspulen aus den Fässern, Schneiden, Ablängen, Abisolieren, Anschlagen und bei der Dichtungsmontage. Um bereits verdrillte Leitungen derartig zu bearbeiten werden Sondermaschinen benötigt. Das erfindungsgmäße Verfahren erlaubt die Verarbeitung auf Standardmaschinen, da das Verdrillen als letzter Fertigungsschritt erfolgen kann. In diesem Zusammenhang ergeben sich auch Verbesserungen in der Prozeßsicherheit und bei der Qualitität der verdrillten Leitungen. Durch das Verfahren können ohne weiteres vorkonfektionierte Leitungen mit Anbauten an den Leitungsenden jeglicher Art verarbeitet werden. Der Entdrillvorgang sorgt dafür, daß keine Torsionsbelastungen an den Enden der Einzelleitungen auftreten.The material stocks can be obtained by the method according to the invention reduce the stock, because not all combinations between line color and cross-section are kept in stock have to. The required line pairs can now be made accordingly the wishes of the cable assembler from standard cables getting produced. In contrast to the processing of Conventionally twisted cables do not cause any problems when Untwisting, smoothing, unwinding from the barrels, cutting, cutting to length, Stripping, attaching and when installing seals. In order to process already twisted cables in this way Special machines needed. The method according to the invention allows processing on standard machines, since the twisting as last manufacturing step can take place. In this context there are also improvements in process security and in the quality of the twisted cables. Through the process can easily be pre-assembled cables with attachments be processed at the cable ends of any kind. The untwisting process ensures that there are no torsional loads occur at the ends of the individual lines.

    Günstigerweise kann das Drillschiff in der Nähe der Verdrillaufnahmen zwischen den Leitungen angeordnet und beim Verdrillvorgang in Richtung der Entdrillspannaufnahmen verfahren werden. Hierdurch läßt sich eine genauere Steuerung des Verdrillvorganges erzielen, da dieser anfänglich möglichst nahe an den Verdrillspannaufnahmen beginnt.Conveniently, the drill ship can be close to the twist shots arranged between the lines and during the twisting process be moved in the direction of the untwisting fixtures. This allows more precise control of the twisting process achieve, since this initially as close as possible to the Twist clamping starts.

    Des weiteren kann die Verfahrgeschwindigkeit des Drillschiffs in Abhängigkeit der Drehzahl der Verdrillspannaufnahmen um die Verdrillachse gesteuert werden. Hierdurch läßt sich die Verdrillsteigung der Einzelleitungen variieren. Das führt sogar so weit, daß ein aus Einzelleitungen verdrilltes Kabel verschiedene Abschnitte mit unterschiedlichen Verdrillsteigungen aufweisen kann. Um die Zugspannungen, die bei dem Verdrillvorgang auf die Einzelleitungen ausgeübt werden, im wesentlichen konstant zu halten, können die Entdrillspannaufnahmen während des Verdrillvorganges auf die Verdrillspannaufnahmen in gesteuerter Weise zu bewegt werden. Durch das Verdrillen der Einzelleitungen von bestimmter Länge, können abhängig von der Verdrillsteigung verständlicherweise nur Kabel geringerer Endlänge hergestellt werden. Diese "Schrumpfung" wird bevorzugt durch gesteuertes Verfahren der Verdrillspannaufnahmen Rechnung getragen. Selbstverständlich können auch die Entdrillspannaufnahmen relativ zu den Verdrillspannaufnahmen bewegt werden. Es hat sich gezeigt, daß eine bestimmte Vorspannung auf den Einzelleitungen den Verdrillvorgang begünstigt.Furthermore, the speed of movement of the drill ship depending on the speed of the twisting fixtures Twist axis can be controlled. This allows the twist pitch of the individual lines vary. That even leads far that a cable twisted from individual lines different Have sections with different twist pitches can. To the tensile stresses that arise during the twisting process the individual lines are exercised, essentially constant can hold the untwist clamping recordings during the twisting process on the twist clamps in controlled Way to be moved. By twisting the individual lines of a certain length, depending on the twist pitch understandably only cables with a smaller final length are manufactured become. This "shrinkage" is preferably controlled by Procedure of the twist clamping recordings taken into account. Of course, the untwisting fixtures can also be relative to be moved to the twisting fixtures. It has shown that a certain bias on the individual lines favors the twisting process.

    Bei einer weiteren Variante wird vorgeschlagen, daß das Ablängen und/oder Einspannen der Einzelleitungen automatisch erfolgt. Entsprechend können noch weitere Zwischenschritte dazugeschaltet werden, wenn die Einzelleitungen jeweils noch vorkonfektioniert werden, z.B. durch entsprechende Anschlüsse an den Enden usw. Diese Maßnahme bietet sich insbesondere bei verdrillten Kabeln mit hohen Stückzahlen an.In a further variant it is proposed that the cutting to length and / or clamping of the individual lines takes place automatically. Accordingly, further intermediate steps can be added if the individual lines are still prefabricated e.g. through appropriate connections the ends etc. This measure is particularly useful for twisted ones Cables with large quantities.

    Günstigerweise können die Entdrillspannaufnahmen nach dem Klemmen der einen Leitungsenden zum Einziehen der Leitungen in eine Verdrillvorrichtung von den Verdrillspannaufnahmen entlang der Verdrillachse wegbewegt werden. Die Entdrillspannaufnahmen werden somit als Vorschubvorrichtung für die Einzelleitungen verwendet.Conveniently, the untwisting fixtures after clamping one line ends for pulling the lines into a Twisting device from the twisting fixtures along the Twisting axis are moved away. The untwist recordings will be thus used as a feed device for the individual lines.

    Dabei kann es vorgesehen sein, daß die bestimmte Einzugslänge geringer ist als der maximale Abstand von Entdrill- und Verdrillspannaufnahmen zu Beginn des Verdrillvorganges und daß nach dem Einspannen der anderen Enden in den Verdrillspannaufnahmen ein Spannen der Leitungen durch nochmaliges Verfahren der Entdrillspannaufnahmen erfolgt. Zum einen erleichtert dieser Vorgang das Einlegen der anderen Enden der Einzelleitungen, da diese noch relativ lose und ohne Vorspannung in die Verdrillspannaufnahmen einlegbar sind und zum anderen wird dann durch das Verfahren der Entdrillspannaufnahmen gezielt eine Vorspannung auf die Einzelleitungen aufgebracht.It can be provided that the particular feed length is less than the maximum distance between untwist and twist clamping fixtures at the start of the twisting process and that after the other ends have been clamped in the twist clamps tensioning the lines by repeating the procedure the untwisting take-up takes place. On the one hand, this makes it easier The process of inserting the other ends of the individual lines, since this is still relatively loose and without pre-tensioning in the twisting fixtures are insertable and then another through the process of the untwisting recordings Bias applied to the individual lines.

    Vorteilhafterweise können die Leitungen im Bereich ihrer Leitungsenden enger verdrillt werden als im restlichen Bereich. Diese engere Verdrillung im Bereich ihrer Leitungsenden stellt eine Art Verknotung und bessere Sicherung der Gesamtverdrillung dar. Somit wird ein unabsichtliches Aufdrillen der Leitungen erschwert.The lines can advantageously be in the region of their line ends are twisted closer than in the rest of the range. This creates tighter twist in the area of their line ends a kind of knotting and better protection of the overall twist Thus, an unintentional untwisting of the lines difficult.

    Des weiteren bezieht sich die Erfindung auf eine Verdrillvorrichtung zum Verdrillen von mindestens zwei Einzelleitungen. Furthermore, the invention relates to a twisting device for twisting at least two individual lines.

    Diese umfaßt mindestens zwei Entdrillspannaufnahmen zum Einspannen von Leitungsenden, die jeweils separat, im wesentlichen parallel zu einer Verdrillachse drehbar angeordnet sind, mindestens zwei den Entdrillspannaufnahmen gegenüberliegend angeordnete Verdrillspannaufnahmen zum Einspannen der anderen Leitungsenden, die gemeinsam um die Verdrillachse drehbar angeordnet sind, und ein zwischen die Leitungen positionierbares Drillschiff, wobei die Entdrillspannaufnahmen und die Verdrillspannaufnahmen relativ zueinander entlang der Verdrillachse bewegbar sind.This comprises at least two untwist clamping receptacles for clamping of line ends, each separately, essentially are arranged rotatably parallel to a twist axis, at least two arranged opposite the untwisting fixtures Twist clamps for clamping the other cable ends, which are arranged together rotatable about the twist axis and a positionable between the lines Drill ship, the untwisting and the twisting shots relative to each other along the twist axis are movable.

    Durch diese Vorrichtung läßt sich in vorteilhafter Weise das erfindungsgemäße Verfahren und die diesem zugrundeliegenden Vorteile ausführen. Diese Vorrichtung baut sehr schmal und muß lediglich die, für die Verdrillung notwendige Ausgangslänge der Einzelleitungen vorgegebene Länge aufweisen.This device can be used in an advantageous manner The inventive method and the underlying Execute benefits. This device is very narrow and must be built only the output length required for twisting the Individual lines have a predetermined length.

    Günstigerweise können dabei die Entdrillspannaufnahmen auf einem gemeinsamen Entdrillschlitten mittels eines Linearantriebes entlang der Verdrillachse verfahrbar angeordnet sein. Der Linearantrieb läßt sich sehr präzise steuern, kann aber auch relativ hohe Einzugsgeschwindigkeiten fahren. Der Antrieb für die Entdrillspannaufnahmen befindet sich dann bevorzugterweise ebenfalls auf dem Enddrillschlitten.Conveniently, the untwist recordings can be made on one common untwisting slide using a linear drive be arranged to be movable along the twist axis. The linear drive can be controlled very precisely, but can also be relative drive high feed speeds. The drive for the Untwist tension recordings are then preferably located also on the final drilling slide.

    Das Drillschiff kann ebenfalls auf einem Schlitten mittels eines Linearantriebs entlang der Verdrillachse verfahrbar angeordnet sein, wodurch sich die Verdrillsteigung genauer einstellen läßt, da der gerade verdrillte Leitungsabschnitt sich immer unmittelbar am Drillschiff befindet. Zur Vereinfachung des Vorrichtungsaufbaus können die Verdrillspannaufnahmen auf einem gemeinsamen, um die Drillachse drehbaren Träger angeordnet sein.The drill ship can also be used on a sled Linear drive arranged movable along the twist axis be, which sets the twist pitch more precisely can, because the just twisted line section always located directly on the drill ship. To simplify the construction of the device can the twist clamps on a common, rotatable about the drill axis arranged carrier his.

    Von Vorteil ist es bei einer Ausführungsform, wenn die Entdrillspannaufnahmen und/oder die Verdrillspannaufnahmen jeweils eine feste und eine bewegliche Spannbacke umfassen. Dadurch braucht lediglich die bewegliche Spannbacke angesteuert werden, um die Enden der Einzelleitungen festzuspannen. Günstigerweise können die Spannbacken einen prismatischen, größenverstellbaren Spannbereich aufweisen. Ein derartig ausgestalteter Spannbereich paßt sich automatisch an die verschiedenen Durchmessergrößen der Einzelleitungen an, so daß ohne Einstellmaßnahmen die verschiedensten Leitungsgrößen verwendet werden können.In one embodiment, it is advantageous if the untwist clamping receptacles and / or the twist clamping recordings in each case comprise a fixed and a movable jaw. Thereby only the movable jaw needs to be controlled, to clamp the ends of the individual lines. Conveniently the jaws can be a prismatic, size adjustable Have clamping range. Such a clamping area automatically adapts to the different diameter sizes of the individual lines so that without adjustment measures different line sizes can be used.

    Damit beim Verdrillvorgang die Spannbacken ohne zusätzliche Energieversorgung, z.B. durch Hydraulik- oder Luftdruck, die Spannfunktion ausüben können, kann die feste und bewegliche Spannbacke durch eine Federeinrichtung in Klemmrichtung vorgespannt sein. Demnach muß lediglich zum Öffnen der Spannbacken eine entsprechende Öffnungskraft aufgebracht werden.So that the clamping jaws without additional during the twisting process Energy supply, e.g. by hydraulic or air pressure that Can exercise the clamping function, can be fixed and movable Clamping jaw biased in the clamping direction by a spring device his. Accordingly, only needs to open the jaws a corresponding opening force can be applied.

    Bei einer weiteren Ausführungsform stellen die Entdrillspannaufnahme und Verdrillspannaufnahme jeweils einen Anschlag für die Leitungsenden bereit, so daß ein postionsgenaues Einlegen erfolgen kann.In a further embodiment, the untwist take-up is provided and twist clamping each have a stop ready for the line ends, so that a position accurate Can be inserted.

    Bevorzugterweise können die Entdrillspannaufnahme und die Verdrillspannaufnahme versetzt zum Klemmbereich der Spannbacken Aufnahmeinrichtungen für Anbauten an den Leitungsenden aufweisen. Dadurch sind die Anbauten relativ geschützt beim Verdrillvorgang positioniert und können nicht beschädigt werden.Preferably, the untwist take-up and the twist take-up offset to the clamping area of the jaws Have mounting devices for attachments at the cable ends. This means that the attachments are relatively protected during the twisting process positioned and cannot be damaged.

    Günstigerweise kann eine Steuereinrichtung vorgesehen sein, die die Drehzahlen der Entdrillspannaufnahmen und Verdrillspannaufnahmen und Verfahrgeschwindigkeiten der Verdrillspannaufnahmen und des Drillschiffs nach vorbestimmten Werten aufeinander abstimmt. Hierdurch lassen sich sehr effizient Einzelleitungen voll automatisch, selbst mit verschiedenen Verdrillsteigungen, programmgenau herstellen.A control device can advantageously be provided, which the speeds of the untwisting and twisting adapters and travel speeds of the twist clamping fixtures and the drill ship is coordinated with one another according to predetermined values. This allows individual lines to be used very efficiently fully automatic, even with different twist pitches, Manufacture to the program.

    Bei einer weiteren Ausgestaltung wird vorgeschlagen, mindestens zwei Verdrillstationen mit den entsprechenden Bauelementen nebeneinander in einer Vorrichtung anzuordnen, wodurch eine Tandemanordnung gebildet ist. Dadurch lassen sich mindestens zwei verdrillte Kabel auf einmal herstellen, wobei die Linearantriebe für beide Verdrillstationen verwendbar sind. In a further embodiment, it is proposed, at least two twisting stations with the corresponding components next to each other to be arranged in a device, whereby a tandem arrangement is formed. This allows at least two Produce twisted cables at once, using the linear drives can be used for both twisting stations.

    Um der Reduzierung der Länge der Einzelleitungen durch den Verdrillvorgang Rechnung zu tragen, können die Verdrillspannaufnahmen mittels einer Vorschubeinrichtung entlang der Linearführungen verfahrbar angeordnet sein. Ein Pneumatikzylinder mit Gegendrucksteuerung kann unter Beibehalten einer gewünschten Vorspannung ein Verfahren, aufgrund der Zugwirkung durch die Längenschrumpfung, der Verdrillspannaufnahmen zulassen.To reduce the length of the individual lines through the twisting process The twist clamps can take into account by means of a feed device along the linear guides be movably arranged. A pneumatic cylinder with Back pressure control can be maintained while maintaining a desired one Preload is a process due to the tensile effect caused by the Length shrinkage, which allow twist clamping.

    Die in den Figuren 1 und 2 dargestellte Verdrillvorrichtung umfaßt im wesentlichen einen Maschinenständer 2 mit Linearführungen 3, und jeweils an den Linearführungen 3 angeordnet einen Verdrillkopf 4, einen Entdrillkopf 5 und ein Drillschiff 6. Der Verdrillkopf 4 besteht im wesentlichen aus einem Verdrillmotor 7 und von diesem angetriebenen Verdrillspannaufnahmen 8. Der Verdrillkopf 4 wird über einen Pneumatikzylinder in Grundstellung gehalten. Beim Verdrillvorgang wird der Verdrillkopf 4 entlang der Linearführungen 3 in Richtung Entdrillkopf 5 verfahren (Gegendruck einstellbar).The twisting device shown in Figures 1 and 2 includes essentially a machine stand 2 with linear guides 3, and each arranged on the linear guides 3 Twisting head 4, an untwisting head 5 and a drilling ship 6. The Twisting head 4 essentially consists of a twisting motor 7 and driven by this twist clamping receptacles 8. The Twisting head 4 is in the basic position via a pneumatic cylinder held. During the twisting process, the twisting head 4 Move along the linear guides 3 in the direction of the untwisting head 5 (Back pressure adjustable).

    Im Gegensatz dazu läßt sich der Entdrillkopf 5, der aus Lageraufnahme 9 und den Entdrillspannaufnahmen 10 besteht, mittels eines Linearantriebs 11 entlang der Linearführungen 3 verfahren.In contrast, the untwisting head 5 can be made from Bearing receptacle 9 and the Entdrillspannaufnahmen 10, means a linear drive 11 move along the linear guides 3.

    Das Drillschiff 6, das im wesentlichen aus einem entlang der Linearführung 3 verfahrbaren Schlitten 12 und einem nach oben gerichteten Dorn 13 gebildet ist, ist ebenfalls durch einen Linearantrieb 14 angetrieben verfahrbar. Der Dorn 13 greift zwischen die Einzelleitungen 15 und 16 ein, die zwischen den Verdrillspannaufnahmen 8 und Entdrillspannaufnahmen 10 angeordnet sind. Des weiteren können innerhalb der Vorrichtung zusätzlich noch Bürstenvorrichtungen zum Beruhigen der Leitungen 15 und 16 während des Verdrillvorgangs angeordnet sein (nicht dargestellt).The drill ship 6, which essentially consists of a along the Linear guide 3 movable carriage 12 and one upwards directed mandrel 13 is also formed by a linear drive 14 driven movable. The mandrel 13 engages between the individual lines 15 and 16, which between the twist tension recordings 8 and Entdrillspannaufnahmen 10 arranged are. Furthermore, additional inside the device still brush devices for calming the lines 15 and 16 be arranged during the twisting process (not shown).

    Des weiteren kann eine Steuervorrichtung vorgesehen sein, die die Verfahrensabläufe an dem Verdrillkopf 4, dem Entdrillkopf 5 und den Linearantrieben 11 und 14 aufeinander abstimmt.Furthermore, a control device can be provided that the process sequences on the twisting head 4, the untwisting head 5 and the linear drives 11 and 14 match each other.

    Als Einzelleitungsbereitsteller kann ein Ständersystem 17 vorgesehen sein, auf dem viele Einzelleitungen 15, 16 parallel nebeneinander angeordnet sind. Bürsten 18 am Ständersystem 17 sorgen dafür, daß durch das Abziehen einzelner Leitungen 15, 16 nicht noch mehr Leitungen von dem Ständersystem 17 herunterbewegt werden. Die Einzelleitungen 15, 16 sind entsprechend vorab abgelängt und gegebenenfalls konfektioniert worden.A stand system 17 can be provided as a single line provider be on which many individual lines 15, 16 in parallel next to each other are arranged. Brushes 18 on the stand system 17 ensure that by pulling individual lines 15, 16th does not move more lines down from the stand system 17 become. The individual lines 15, 16 are accordingly in advance cut to length and possibly assembled.

    Wie in Figur 2 zu erkennen ist, handelt es sich bei der dargestellten Verdrillvorrichtung 1 um eine Tandemanlage mit einer ersten Verdrillstation 19 und einer zweiten Verdrillstation 20.As can be seen in Figure 2, it is the illustrated Twisting device 1 around a tandem system with a first twisting station 19 and a second twisting station 20.

    Anhand der Figuren 3 und 4 werden nun im folgenden der Verdrillkopf 4 und Entdrillkopf 5 näher beschrieben. The twisting head will now be described with reference to FIGS. 3 and 4 4 and Entdrillkopf 5 described in more detail.

    Der Verdrillkopf 4 (Figur 3) umfaßt bei der dargestellten Vorrichtung einen um eine Verdrillachse A drehbaren Träger 19, auf dem zwei Verdrillspannaufnahmen 8 symmetrisch zur Verdrillachse A angeordnet sind. Die Verdrillspannaufnahmen 8 umfassen eine feste Spannbacke 20 mit prismatischem Klemmeinsatz 21 und eine bewegliche Spannbacke 22 mit prismatischem Klemmeinsatz 23. Die Klemmeinsätze 21 und 23 umgrenzen eine quaderförmige Spannöffnung 24, die durch kammartiges Ineinandergreifen der Klemmeinsätze 21 und 23 in ihre Größe verstellbar ist. Die bewegliche Backe 22 ist mit einem drehbaren Öffnungsrad 24 mit Eingriffszähnen 25 verbunden. Im dargestellten Zustand sind die feste Backe 20 und bewegliche Backe 22 durch eine Federeinrichtung zur Erzeugung der Klemmwirkung aufeinander zugedrückt, so daß das Öffnungsrad 24 zum Öffnen entgegen der Wirkung der Federeinrichtung Verwendung findet.The twisting head 4 (FIG. 3) comprises in the device shown a carrier 19 rotatable about a twisting axis A. the two twist clamping receptacles 8 symmetrical to the twist axis A are arranged. The twist clamping receptacles 8 comprise one fixed jaw 20 with prismatic clamping insert 21 and one movable jaw 22 with prismatic clamping insert 23. Die Clamping inserts 21 and 23 delimit a cuboid clamping opening 24 by comb-like interlocking of the clamping inserts 21 and 23 is adjustable in size. The moveable Jaw 22 is with a rotatable opening gear 24 with engagement teeth 25 connected. In the state shown are the fixed ones Jaw 20 and movable jaw 22 by a spring device pressed together to produce the clamping effect, so that the opening wheel 24 for opening against the action of the spring device Is used.

    Zum Bewegen der beweglichen Backe 22 ist eine Öffnungsvorrichtung 26 vorgesehen, die eine höhenverstellbare Pneumatikeinheit 27 umfaßt, die mit ihrem Kolben 28 auf ebenfalls höhenbewegliche Zahnstangenabschnitte 29 und 30 wirkt. Diese Zahnstangenabschnitte 29 und 30 können mit den Eingriffszähnen 25 der Öffnungsräder 24 in Eingriff gebracht werden, wobei durch Bewegen des Kolbens 28 nach links die beweglichen Backen 22 in ihre Öffnungsstellung überführt werden. Da die Klemmwirkung durch die nicht dargestellte Federeinrichtung an den Backen 20 und 22 erreicht wird, wird die Öffnungsvorrichtung 26 nur im Öffnungsfalle entsprechend hoch und in Eingriff mit den Öffnungsrädern 24 gefahren.To move the movable jaw 22 is an opening device 26 provided a height adjustable pneumatic unit 27 comprises, with its piston 28 on also vertically movable Rack sections 29 and 30 acts. These rack sections 29 and 30 can with the engagement teeth 25 of the opening wheels 24 can be engaged by moving of the piston 28 to the left the movable jaws 22 in their Open position are transferred. Because the clamping effect by the spring device, not shown, on the jaws 20 and 22 is reached, the opening device 26 is only in the opening case correspondingly high and in engagement with the opening wheels 24 driven.

    Aus der Anordnung der Verdrillspannaufnahmen 8 auf dem Träger 19 ergibt sich, daß diese ebenfalls um die Verdrillachse A rotieren, ohne ihre relative Lage zum Träger 19 zu verändern.From the arrangement of the twist clamping receptacles 8 on the carrier 19 results that they also rotate about the twisting axis A, without changing their position relative to the carrier 19.

    Der Entdrillkopf 5 (Figur 4) umfaßt zwei Entdrillspannaufnahmen 10, die jeweils für sich um parallel zur Verdrillachse A angeordnete Drehachsen drehbar sind. Da der Aufbau der Entdrillspannaufnahmen 10 und der Öffnungsvorrichtung 26 ansonsten dem Aufbau der Verdrillspannaufnahmen 8 entspricht, können die gleichen Bezugsziffern verwendet und auf die genauere Beschreibung verzichtet werden. Ergänzend sei noch darauf hingewiesen, daß der Entdrillkopf 5 mit der Lageraufnahme 9 entlang der Linearführung 3 verfahrbar ist, wobei er durch den Linearantrieb 11 angetrieben ist. Die Entdrillspannaufnahmen 10 sind entweder gemeinsam durch einen einzigen Antrieb oder durch einen individuellen Antrieb angetrieben oder lediglich gelagert. Auch eine Kopplung mit dem Linearantrieb 11 ist durchaus möglich.The untwisting head 5 (FIG. 4) comprises two untwisting clamping receptacles 10, each arranged separately about the twist axis A Axes of rotation are rotatable. Because the structure of the untwist recordings 10 and the opening device 26 otherwise corresponds to the structure of the twist clamping receptacles 8, the same reference numerals and on the more detailed description to be dispensed with. In addition, it should be pointed out that the untwisting head 5 with the bearing receptacle 9 along the linear guide 3 is movable, it is due to the linear drive 11 is driven. The untwist fixtures 10 are either together by a single drive or by an individual Drive driven or just stored. Also one Coupling with the linear drive 11 is quite possible.

    Unter Zuhilfenahme der Figuren 5, 6 und 7 wird nun im folgenden die Wirkungs- und Funktionsweise des oben beschriebenen Ausführungsbeispieles näher erläutert.With the help of Figures 5, 6 and 7 will now be the following the effect and functionality of the embodiment described above explained in more detail.

    In den Draufsichten ist zusätzlich noch zu erkennen, daß die Klemmeinsätze 21 und 23 kürzer sind als die bewegliche Backe 22 und feste Backe 20, so daß axial versetzt zu den Klemmeinsätzen 21, 23 eine Aufnahmeaussparung 31 gebildet ist, in der Anbauten 32, z.B. Kontaktanschlüsse, der Einzelleitungen 15, 16 aufgenommen sind.In the top views it can also be seen that the Clamping inserts 21 and 23 are shorter than the movable jaw 22 and fixed jaw 20 so that it is axially offset from the clamping inserts 21, 23 a receiving recess 31 is formed in the extensions 32, e.g. Contact connections, the individual lines 15, 16 added are.

    Anhand der Figur 5 ist zu erkennen, daß zwei Leitungen 15, 16 von dem Ständersystem 17 abgezogen und deren erste Enden 33 mit den Kontaktanschlüssen 32 in die Entdrillspannaufnahmen 10 eingelegt worden sind. Dabei wird jeweils eine einzige der Leitungen 15, 16 in eine entsprechende Entdrillspannaufnahme 10 eingelegt. Hierzu muß die bewegliche Backe 22 geöffnet werden durch die Öffnungsvorrichtung 26. Die Enden 33 werden dann bis zu einer Anschlagfläche der Entdrillspannaufnahme 10 vorgeschoben, damit sie genau positioniert sind. Anschließend wird durch Bewegen des Kolbens 28 und/oder direktes Herunterfahren der Öffnungsvorrichtung 26 die bewegliche Backe 22 geschlossen. Die Klemmöffnung 24' paßt sich dann durch das kammartige Ineinandergreifen der Klemmeinsätze 21 und 23 automatisch an den entsprechenden Durchmesser der Einzelleitungen 15, 16 an und klemmt diese.It can be seen from FIG. 5 that two lines 15, 16 deducted from the stand system 17 and the first ends 33 with the contact terminals 32 inserted into the untwist receptacles 10 have been. Each one of the lines 15, 16 inserted into a corresponding untwist take-up 10. For this purpose, the movable jaw 22 must be opened through the opening device 26. The ends 33 are then up to advanced to a stop surface of the untwisting fixture 10, so that they are positioned exactly. Then through Moving the piston 28 and / or directly shutting down the Opening device 26 closed the movable jaw 22. The Clamp opening 24 'then fits through the comb-like interlocking of the clamping inserts 21 and 23 automatically on the corresponding Diameter of the individual lines 15, 16 and clamps this.

    Der Entdrillkopf 5 befindet sich bei diesem Vorgang in der Nähe des Verdrillkopfes 4 und wird nach Festklemmen der Einzelleitungen 15, 16 in die Richtung B verschoben, so daß die Leitungen 15, 16 in die Vorrichtung eingezogen werden. Dabei wird der Entdrillkopf 5 nur so weit verfahren, daß die anderen Enden 35 der Leitungen 15, 16 ohne Spannung in die geöffneten Backen 20, 22 des Verdrillkopfes 4 einlegbar und bis zur Anschlagfläche 34 vorschiebbar sind.The untwist head 5 is in the vicinity during this process of the twisting head 4 and is after clamping the individual lines 15, 16 moved in the direction B, so that the lines 15, 16 are drawn into the device. The Untwist head 5 only move so far that the other ends 35 the lines 15, 16 without tension into the open jaws 20, 22 of the twisting head 4 can be inserted and up to the stop surface 34 can be pushed forward.

    Das Öffnen und Schließen der Verdrillspannaufnahmen 8 erfolgt dann über die Öffnungsvorrichtung 26 in ähnlicher Weise wie beim Entdrillkopf 5 (siehe Figur 6).The twisting clamping receptacles 8 are opened and closed then via the opening device 26 in a similar manner as at the untwisting head 5 (see FIG. 6).

    Nachdem die anderen Enden 35 ebenfalls einzeln in die Verdrillspannaufnahmen 8 eingebracht worden sind, verfährt der Entdrillkopf 5 abermals in Richtung B, um die endgültige Spannung auf die Leitungen 15, 16 aufzubringen. Die Leitungen 15, 16 erstrecken sich nun im wesentlichen parallell zueinander. Der Dorn 13 des Drillschiffes 6 ist entweder bei diesem Vorgang automatisch zwischen den Leitungen angeordnet oder fährt entsprechend in diese Stellung vor Beginn des eigentlichen Verdrillvorganges.After the other ends 35 also individually in the twist clamping receptacles 8 have been introduced, the Untwist head 5 again in direction B to the final tension to apply to the lines 15, 16. The lines 15, 16 now extend essentially parallel to each other. The mandrel 13 of the drill ship 6 is either in this process automatically arranged between the lines or moves accordingly in this position before the actual twisting process begins.

    Beim Verdrillvorgang (siehe Figur 7) wird nun der Verdrillkopf 4 um die Verdrillachse A gedreht. Dadurch kreuzen sich die Leitungen 15, 16 im Bereich des Dorns 13 und verdrillen sich. Gleichzeitig werden die Entdrillspannaufnahmen 10 des Entdrillkopfes 5 einzeln und parallel zur Verdrillachse A in gleicher Richtung wie der Verdrillkopf 4 gedreht, so daß sich in den Einzelleitungen 15, 16 keine Torsionsspannung aufbauen kann. Die Leitungen 15, 16 führen demnach lediglich eine Verdrillbewegung aus, ohne jedoch eine Torsionsbewegung um ihre jeweilige eigene Achse auszuführen, was unter Umständen zu unzulässig hohen Spannungen und Beschädigung der Leitung führen könnte.During the twisting process (see Figure 7) the twisting head is now 4 rotated about the twisting axis A. This will cause the lines to cross 15, 16 in the area of the mandrel 13 and twist. At the same time, the untwisting fixtures 10 of the untwisting head 5 individually and parallel to the twisting axis A in the same Direction as the twisting head 4 rotated, so that in the Individual lines 15, 16 can not build up any torsional stress. The lines 15, 16 therefore only perform a twisting movement without, however, a torsional movement about their respective to execute their own axis, which may be too high Tension and damage to the line could result.

    Der Abstand zwischen Verdrillkopf 4 und Entdrillkopf 5 muß sich während des Verdrillvorganges verringern, da die Länge des verdrillten Kabels immer kürzer ist als die Einzellänge der Leitungen 15, 16. Bei dieser Vorrichtung bewegt sich der Verdrillkopf 4 in Richtung B' auf den Entdrillkopf 5 beim Verdrillvorgang zu. Dabei wird weiterhin eine entsprechende Spannung auf den Leitungen 15, 16 gehalten. Der Linearantrieb 11 kann entsprechend kraftgesteuert betrieben werden. The distance between the twisting head 4 and the untwisting head 5 must be the same reduce during the twisting process because the length of the twisted Cable is always shorter than the individual length of the cables 15, 16. In this device, the twisting head moves 4 in direction B 'on the untwisting head 5 during the twisting process to. A corresponding voltage will continue to be applied the lines 15, 16 held. The linear drive 11 can accordingly operated under power control.

    Des weiteren läßt sich durch eine Steuereinrichtung die Drehgeschwindigkeit des Verdrillkopfes 4 und die Verfahrgeschwindigkeit C des Drillschiffes 6 aufeinander abstimmen, so daß die Verdrillsteigung einstellbar ist. Bevorzugterweise werden die Leitungen 15, 16 in der Nähe des Verdrillkopfes 4 und Entdrillkopfes 5 enger verdrillt, so daß sich eine Art Knotenwirkung einstellt, die das unabsichtliche Aufdrillen nochmals erschwert.Furthermore, the speed of rotation can be controlled by a control device of the twisting head 4 and the travel speed C of the drill ship 6 coordinate so that the Twist pitch is adjustable. Preferably, the Lines 15, 16 in the vicinity of the twisting head 4 and untwisting head 5 twisted closer, so that there is a kind of knot effect sets, which makes unintentional untwisting even more difficult.

    Nach Fertigstellen des verdrillten Kabels werden die Verdrillspannaufnahmen 8 und Entdrillspannaufnahmen 10 wieder durch die Öffnungsvorrichtung 26 geöffnet und das Kabel entnommen.After the twisted cable has been completed, the twist clamping fixtures 8 and untwisting 10 again opened by the opening device 26 and the cable removed.

    Verständlicherweise können auf einer derartigen Verdrillvorrichtung 1 Leitungen mit unterschiedlichen Leitungsquerschnitten, z.B. 0,35 bis 2,5 mm2 und unterschiedlicher Länge, z.B. 0,4 bis 8 m, verdrillt werden. Dabei ist es möglich, daß die Leitungsenden 33 und 35 Anbauten 32, z.B. in Form von Kontaktanschlüssen, Gehäusen usw., aufweisen, die in den Aufnahmeaussparungen 31 aufgenommen werden. Dies ist möglich, weil keine Torsion auf die Einzelleitungen 15, 16 beim Verdrillvorgang ausgeübt wird. Wichtig ist es dabei, daß die durch die Verdrillspannaufnahmen 8 erzeugte Verdrehung der Einzelleitungen durch die Entdrillspannaufnahmen 10 wieder aufgehoben werden.Understandably, lines with different line cross sections, for example 0.35 to 2.5 mm 2 and different lengths, for example 0.4 to 8 m, can be twisted on such a twisting device 1. It is possible for the line ends 33 and 35 to have attachments 32, for example in the form of contact connections, housings, etc., which are accommodated in the recesses 31. This is possible because no torsion is exerted on the individual lines 15, 16 during the twisting process. It is important here that the twisting of the individual lines generated by the twisting clamping receptacles 8 is canceled again by the untwisting clamping receptacles 10.
