Gemäß der vorliegenden Offenbarung übernimmt die Transfereinheit ein Ende des verdrillten Leitungspaars und hält dieses. Der erste Leitungsgreifer der Transfereinheit hält die erste Einzelleitung, und der zweite Leitungsgreifer hält die zweite Einzelleitung. Der Abstand zwischen dem ersten Leitungsgreifer und dem zweiten Leitungsgreifer ist veränderlich, und zwar entsprechend dem Abstand der Enden der Einzelleitungen. In der Regel wird der Abstand zwischen dem ersten Leitungsgreifer und dem zweiten Leitungsgreifer verringert, so dass der Abstand der Enden der Einzelleitungen ebenfalls entsprechend geringer wird.According to the present disclosure, the transfer unit accepts and holds one end of the twisted pair of wires. The first line gripper of the transfer unit holds the first single line, and the second line gripper holds the second single line. The distance between the first line gripper and the second line gripper is variable, according to the distance of the ends of the individual lines. In general, the distance between the first line gripper and the second line gripper is reduced, so that the distance between the ends of the individual lines is also correspondingly lower.

Die nachverdrillten Enden der Leitungen im verdrillten Leitungspaar weisen nach Abschluss des Nachverdrillens bei hoher Qualität einen kleineren Abstand auf.Subsequently, the reduced in the spaced ends of the individual lines are twisted. The twisted ends of the Wires in the twisted pair of wires have a smaller distance at the end of the post-twisting with high quality.
Typischerweise ist der Abstand zwischen dem ersten Leitungsgreifer und dem zweiten Leitungsgreifer programmierbar veränderlich. Ein programmierbares Verändern umfasst beispielsweise ein Anpassen des Abstands zwischen dem ersten Leitungsgreifer und dem zweiten Leitungsgreifer entsprechend einer vorgegebenen oder vorgebbaren Leitungskonfiguration (Vorgabe einer Distanz einer ersten Kreuzungsposition, Schlaglänge der Verdrillung etc.) und/oder entsprechend einer Leitungsbeschaffenheit (Leitungsquerschnitt, Stärke der Isolierung etc.).Typically, the distance between the first line gripper and the second line gripper is programmably variable. Programmable modification includes, for example, adjusting the distance between the first line gripper and the second line gripper according to a predetermined or predeterminable line configuration (specification of a distance of a first intersection position, lay length of the twist, etc.) and / or according to a line condition (line cross section, thickness of the insulation, etc .).

Jeder Nachverdrillkopf hält die beiden Einzelleitungen des verdrillten Leitungspaars und führt eine vorgegebene oder vorgebbare, typischerweise programmierbare, Anzahl von Umdrehungen für das Nachverdrillen aus.In embodiments, at least one of stationary post-blending module and portable post-twisting module comprises a post-twisting head. Each post-twisting head holds the two individual wires of the twisted pair of wires and executes a predetermined or specifiable, typically programmable, number of revolutions for post-twisting.
Bei Ausführungsformen ist mindestens einer der Nachverdrillköpfe in der Verlaufsrichtung des Leitungspaars bewegbar, so dass eine Zugkraft auf das Leitungspaar aufgebracht wird. Mit dem Aufbringen einer Zugkraft können Leitungsparameter wie z. B. die Schlaglänge auch für den nachverdrillten Leitungsabschnitt am Leitungsende gewährleistet werden. Der mindestens eine der Nachverdrillköpfe kann kraftgeregelt bewegbar ausgeführt sein, um eine vorgegebene oder vorgegebene Zugkraft auf das Leitungspaar aufzubringen.In embodiments, at least one of the Nachverdrillköpfe is movable in the direction of the line pair, so that a tensile force is applied to the pair of wires. With the application of a tensile force line parameters such. B. the lay length are guaranteed even for the post-twisted line section at the end of the line. The at least one of Nachverdrillköpfe can be designed to be movable under power, to apply a predetermined or predetermined tensile force on the pair of wires.
Bei Ausführungsformen ist das ortsveränderliche Nachverdrillmodul als Wagen ausgebildet, der an einer Linearführung der Vorrichtung bereitgestellt und entlang der Linearführung in der linearen Führungsrichtung geführt bewegbar ist. Eine Ausführung als linear geführter Wagen ermöglicht einen besonders einfachen und effektiven Aufbau. Der Wagen kann mittels eines Zahnriemenantriebs bewegbar sein, was den Aufbau abermals vereinfacht.In embodiments, the portable Nachverdrillmodul is designed as a carriage which is provided on a linear guide of the device and guided along the linear guide in the linear guide direction is movable. An execution as a linearly guided car allows a particularly simple and effective construction. The carriage can be moved by means of a toothed belt drive, which simplifies the structure again.
Bei Ausführungsformen umfasst das ortsveränderliche Nachverdrillmodul weiter einen Antrieb zum Bewegen eines jeweiligen gehaltenen Endes der Leitungen in Leitungsrichtung umfasst. Der Antrieb ist typischerweise als Spindelantrieb ausgebildet.In embodiments, the portable post-twist module further comprises a drive for moving a respective held end of the lines in the conduit direction. The drive is typically designed as a spindle drive.
Bei Ausführungsformen umfasst die Transfereinheit weiter einen Horizontalantrieb und einen Vertikalantrieb, wobei der Horizontalantrieb und der Vertikalantrieb so konfiguriert sind, dass sie mindestens einen von erstem und zweitem Leitungsgreifer in einer rechtwinklig zur Kabelachse liegenden Ebene senkrecht und waagerecht bewegen. Beispielsweise ist der Horizontalantrieb ein Horizontal-Spindelantrieb. Beispielsweise ist der Vertikalantrieb ein Vertikal-Spindelantrieb.In embodiments, the transfer unit further comprises a horizontal drive and a vertical drive, wherein the horizontal drive and the vertical drive are configured so that they move at least one of first and second line gripper in a plane perpendicular to the cable axis perpendicular and horizontal. For example, the horizontal drive is a horizontal spindle drive. For example, the vertical drive is a vertical spindle drive.
Gemäß einem weiteren Aspekt wird ein Verfahren zum Verdrillen einer ersten und zweiten elektrischen Einzelleitung zu einem Leitungspaar unter Verwendung einer hierin beschriebenen Vorrichtung angegeben. Das Verfahren umfasst ein Verdrillen der elektrischen Einzelleitungen mit dem Hauptverdrillmodul, um ein verdrilltes Leitungspaar zu erhalten; ein Bewegen der Leitungsgreifer des Transfermoduls zu einer Position entsprechend einer zugehörigen Einzelleitung des verdrillten Leitungspaars; ein Übergeben der Einzelleitungen an den jeweils zugehörigen Leitungsgreifer; ein Verkleinern des Abstands zwischen den Leitungsgreifern; ein Verbringen des verdrillten Leitungspaars an eine Nachverdrillposition; ein Übergeben des verdrillten Leitungspaars an die Nachverdrillköpfe der Nachverdrillmodule; und ein Nachverdrillen des verdrillten Leitungspaars.According to another aspect, there is provided a method of twisting a first and second single electrical line to a pair of lines using a device described herein. The method includes twisting the single electrical leads to the main twisting module to obtain a twisted pair of leads; moving the line grippers of the transfer module to a position corresponding to an associated single line of the twisted pair cable; a transfer of the individual lines to the respective associated line gripper; reducing the distance between the line grippers; bringing the twisted pair of wires to a post-twisting position; passing the twisted pair of wires to the post-twist heads of the post-twist modules; and a post-twisting of the twisted pair of wires.
Mit dem Verfahren kann ein Nachverdrillvorgang mit verkleinertem Abstand zwischen den Einzelleitungen an den Enden des Leitungspaars automatisiert werden. Beispielsweise ist über eine Bedienoberfläche der Abstand der Einzelleitungen an einem oder an beiden Enden des Leitungspaars vorgebbar. Es ist auch denkbar, dass ein Abstand einer ersten Kreuzungsposition der Einzelleitungen an dem jeweiligen Ende zum Leitungsende vorgebbar ist. Die erste Kreuzungsposition der Einzelleitungen ist die Position, ausgehend von dem jeweils betrachteten Ende, an welcher die Leitungen zum Ausbilden des verdrillten Zustands erstmals aneinander anliegen bzw. sich überkreuzen.The method can automate a post-twisting operation with reduced spacing between the individual wires at the ends of the wire pair. For example, the distance of the individual lines at one or both ends of the line pair can be predetermined via a user interface. It is also conceivable that a distance of a first crossing position of the individual lines at the respective end to the line end can be predetermined. The first crossing position of the individual lines is the position, starting from the respectively considered end, at which the lines for forming the twisted state first abut each other or cross each other.
Bei Ausführungsformen wird beim Nachverdrillen das verdrillte Leitungspaar von einem der Leitungsgreifer oder von einem Fixiergreifer fixiert. Dadurch ist ein besonders einfaches und sicheres Nachverdrillen gewährleistet.In embodiments, in the post-twisting, the twisted wire pair is fixed by one of the wire grippers or by a fixing gripper. This ensures a particularly simple and secure Nachverdrillen.
Bei Ausführungsformen wird vor dem Verbringen des verdrillten Leitungspaars an die Nachverdrillposition das ortsveränderliche Nachverdrillmoduls in Richtung auf das ortsfeste Nachverdrillmodul zu bewegt. Das Leitungspaar wird also vor dem Verbringen entspannt. Ein Entspannen des Leitungspaars verringert die Gefahr, dass sich die gehaltenen Einzelleitungen aus den Leitungsgreifern lösen oder in ihrer Position verändert werden.In embodiments, before moving the twisted pair of wires to the post-twisting position, the portable post-twisting module is moved toward the stationary post-twisting module. The pair of wires is thus relaxed before moving. A relaxation of the line pair reduces the risk that the held individual lines from the line grippers to solve or changed their position.
Bei Ausführungsformen wird vor dem Nachverdrillen des verdrillten Leitungspaars und während des Nachverdrillens eine Zugkraft auf das zu verdrillende Leitungspaar ausgeübt.In embodiments, before the post-twisting of the twisted pair of wires and during the post-twisting, a tensile force is exerted on the pair of wires to be twisted.
