Definitions
- the invention relates to a twisting device and a method for twisting electrical or optical lines, such as wires, cables, wire bundles, optical fibers, etc., with a base and a first, relative to the base rotatable twisting head, which is formed around the lines to be twisted to grab at their first ends.
- electrical or optical lines such as wires, cables, wire bundles, optical fibers, etc.
- Twisted lines are e.g. in vehicles, aircraft, etc., used to reduce as much as possible interference on and from other lines.
- the twisted wires must meet specifications. You must have a defined uniform lay length over the total length and the insulation must not be damaged.
- the average length of twisted wires in the automobile e.g. is about 4 meters.
- Twisting machines are u.a. known from the following publications
- Cables are in the prior art at one end of the line by a driven twisting head in rotation about the longitudinal axis offset, while the opposite ends of the line are clamped in the holder stationary.
- the speed of the twisting head is limited in terms of process reliability and the protection of the lines.
- Twisting device including methods to provide, with the duration of the actual Verdrillvorganges can be significantly reduced. At the same time, the lines should be optimally protected. The twisting process should be so
- twisting head of the type mentioned above in that the twisting device has a second, relative to the base rotatable twisting head, which is arranged opposite the first twisting head and is adapted to the twisted lines at their second, opposite the first ends Grasping ends, and that the second twisting head is rotatable in opposite sense to the first twisting head.
- the twisting time is approximately halved.
- the lines to be twisted are handled just as gently in the process as in twisting devices with only one-sided twisting drive.
- the twisting heads are spaced from each other by approximately the length of the lines to be twisted. This distance is preferably variable in order, on the one hand, to be adaptable to different cable lengths and, on the other hand, to exert a predetermined tensile force on the lines to be twisted during the twisting operation.
- the twisting heads are mounted on the base so that they have substantially the same axis as a rotation axis. When tensioned lines this axis coincides approximately with the longitudinal axes of the lines.
- the common base may be a rack, a table, a suspension, a pedestal, a mounting platform, a rail and the like.
- the lines are offset at both ends of lines of counter-rotating Verdrillköpfen in rotary motion about its longitudinal axis and twisted in this way in their total length with each other.
- the twisted cable ends in the twisting head are not twisted.
- the twisting heads preferably have their own drives.
- the acceleration of the twisting head and thus the lines around the longitudinal axis is initially slow, so that the individual lines can form uniform wraps over the entire length with each other and are stabilized in the cohesion. Thereafter, the Verdrill process is further accelerated to the final speed, the lines are held in the longitudinal direction with a defined tensile force on.

VERDRILLVORRICHTUNG twisting
Die Erfindung betrifft eine Verdrillvorrichtung und ein Verfahren zum Verdrillen von elektrischen oder optischen Leitungen, wie Drähten, Kabeln, Leitungsbündel, Lichtleitfasern, etc., mit einer Basis und einem ersten, relativ zur Basis drehbaren Verdrillkopf, der ausgebildet ist, um die zu verdrillenden Leitungen an ihren ersten Enden zu greifen. The invention relates to a twisting device and a method for twisting electrical or optical lines, such as wires, cables, wire bundles, optical fibers, etc., with a base and a first, relative to the base rotatable twisting head, which is formed around the lines to be twisted to grab at their first ends.
Verdrillte Leitungen werden z.B. in Fahrzeugen, Flugzeugen, etc., eingesetzt, um Störeinflüsse auf und von anderen Leitungen möglichst weitgehend zu reduzieren. Die verdrillten Leitungen müssen Spezifikationen entsprechen. Sie müssen über die Gesamtlänge eine definierte gleichmässige Schlaglänge besitzen und die Isolation darf nicht beschädigt sein. Die durchschnittliche Länge von verdrillten Leitungen im Automobil z.B. liegt bei ca. 4 Metern. Twisted lines are e.g. in vehicles, aircraft, etc., used to reduce as much as possible interference on and from other lines. The twisted wires must meet specifications.

Die zunächst parallel an den Leitungsenden in Halterungen eingespannten The first clamped in parallel at the line ends in brackets
Leitungen werden nach dem bekannten Stand der Technik an einem Leitungsende durch einen angetriebenen Verdrillkopf in Rotation um die Längsachse versetzt, während die gegenüberliegenden Leitungsenden in der Halterung stationär eingespannt sind. Cables are in the prior art at one end of the line by a driven twisting head in rotation about the longitudinal axis offset, while the opposite ends of the line are clamped in the holder stationary.
Der sich aus dem bekannten Stand der Technik ergebende Nachteil ist The disadvantage resulting from the known state of the art
insbesondere darin zu sehen, dass der eigentliche Verdrillvorgang eine zeitliche Prozessoptimierung verhindert. Die Drehzahl des Verdrillkopfes ist im Hinblick auf die Prozesssicherheit und die Schonung der Leitungen beschränkt. in particular to see that the actual twisting prevents temporal process optimization. The speed of the twisting head is limited in terms of process reliability and the protection of the lines.
Die Erfindung setzt sich zum Ziel, diesen Nachteil zu beseitigen und eine The invention has for its object to eliminate this disadvantage and a
Verdrillvorrichtung samt Verfahren zur Verfügung zu stellen, mit dem die Dauer des eigentlichen Verdrillvorganges wesentlich reduziert werden kann. Gleichzeitig sollen die Leitungen optimal geschont werden. Der Verdrillprozess soll also Twisting device including methods to provide, with the duration of the actual Verdrillvorganges can be significantly reduced. At the same time, the lines should be optimally protected. The twisting process should be so
leitungsschonend verlaufen. Die Leitungsisolation und die Kupferlitzen dürfen nicht beschädigt werden. Ein zuverlässiger und einfach zu programmierender run gently. The cable insulation and the copper strands must not be damaged. A reliable and easy to program
Prozessablauf soll gewährleistet sein. Dieses Ziel wird mit einem Verdrillkopf der eingangs genannten Art dadurch erreicht, dass die Verdrillvorrichtung einen zweiten, relativ zur Basis drehbaren Verdrillkopf aufweist, der dem ersten Verdrillkopf gegenüberliegend angeordnet ist und ausgebildet ist, um die zu verdrillenden Leitungen an ihren zweiten, den ersten Enden gegenüberliegenden Enden zu greifen, und dass der zweite Verdrillkopf in gegenläufigem Sinn zum ersten Verdrill köpf drehbar ist. Process flow should be guaranteed. This object is achieved with a twisting head of the type mentioned above in that the twisting device has a second, relative to the base rotatable twisting head, which is arranged opposite the first twisting head and is adapted to the twisted lines at their second, opposite the first ends Grasping ends, and that the second twisting head is rotatable in opposite sense to the first twisting head.
Durch Einsatz von gegenläufig rotierenden Verdrillköpfen an beiden Leitungsenden wird die Verdrillzeit annähernd halbiert. Dabei werden die zu verdrillenden Leitungen im Prozess ebenso schonend behandelt, wie bei Verdrilleinrichtungen mit nur einseitigem Verdrillantrieb. Die Verdrillköpfe sind voneinander um etwa die Länge der zu verdrillenden Leitungen beabstandet. Dieser Abstand ist vorzugsweise variabel, um einerseits auf verschiedene Kabellängen adaptierbar zu sein und andererseits während des Verdrillvorganges eine vorbestimmte Zugkraft auf die zu verdrillenden Leitungen auszuüben. Die Verdrillköpfe sind dabei so an der Basis gelagert, dass sie im Wesentlichen dieselbe Achse als Drehachse aufweisen. Bei gespannten Leitungen fällt diese Achse in etwa mit den Längsachsen der Leitungen zusammen. Die gemeinsame Basis kann ein Gestell, ein Tisch, eine Aufhängung, ein Sockel, eine Montageplattform, eine Schiene und dgl. sein. By using counter-rotating twist heads on both ends of the cable, the twisting time is approximately halved. In the process, the lines to be twisted are handled just as gently in the process as in twisting devices with only one-sided twisting drive. The twisting heads are spaced from each other by approximately the length of the lines to be twisted. This distance is preferably variable in order, on the one hand, to be adaptable to different cable lengths and, on the other hand, to exert a predetermined tensile force on the lines to be twisted during the twisting operation. The twisting heads are mounted on the base so that they have substantially the same axis as a rotation axis. When tensioned lines this axis coincides approximately with the longitudinal axes of the lines. The common base may be a rack, a table, a suspension, a pedestal, a mounting platform, a rail and the like.
Die Leitungen werden an beiden Leitungsenden von gegenläufig angetriebenen Verdrillköpfen in Drehbewegung um ihre Längsachse versetzt und auf diese Weise in ihrer Gesamtlänge miteinander verdrillt. Nicht verdrillt werden die im Verdrillkopf eingespannten Leitungsenden. Die Verdrillköpfe besitzen vorzugsweise eigene Antriebe. The lines are offset at both ends of lines of counter-rotating Verdrillköpfen in rotary motion about its longitudinal axis and twisted in this way in their total length with each other. The twisted cable ends in the twisting head are not twisted. The twisting heads preferably have their own drives.
Das Beschleunigen des Verdrillkopfes und damit der Leitungen um die Längsachse erfolgt zunächst langsam, so dass die einzelnen Leitungen über die Gesamtlänge miteinander gleichmässige Umschlingungen bilden können und im Zusammenhalt stabilisiert werden. Danach wird der Verdrill prozess weiter bis zur Enddrehzahl beschleunigt, wobei die Leitungen in Längsrichtung mit einer definierten Zugkraft auf Spannung gehalten werden. The acceleration of the twisting head and thus the lines around the longitudinal axis is initially slow, so that the individual lines can form uniform wraps over the entire length with each other and are stabilized in the cohesion. Thereafter, the Verdrill process is further accelerated to the final speed, the lines are held in the longitudinal direction with a defined tensile force on.
Das Verdrillen erfolgt nach einstellbaren Programmen. Zunächst wird eine vorwählbare Anzahl an Umdrehungen in eine Richtung verdrillt, danach wird gezielt in entgegengesetzter Drehrichtung zurückgedreht, so dass die fertig verdrillte Leitung keine nach aussen wirkende Spannung aufweist. Das ist der Fall, wenn die verdrillte, nicht mehr eingespannte Leitung auf einer Fläche gestreckt liegenbleibt, ohne sich zu krümmen, sich nicht um die eigene Achse dreht oder Schlingen bildet. The twisting takes place according to adjustable programs. First, a preselectable number of revolutions is twisted in one direction, then it is rotated back in the opposite direction of rotation, so that the finished twisted Line has no externally acting voltage. This is the case when the twisted, no longer clamped pipe remains stretched on a surface without bending, turning on its own axis or forming loops.
Verdrilleinrichtungen nach dem bekannten Stand der Technik haben einen Twisting devices according to the known prior art have one
Verdrillantrieb an nur einem Leitungsende und eine nicht rotierende Twist drive at only one end of the line and one non-rotating
Leitungshalterung am zweiten Leitungsende. Der Verdrillvorgang dauert also bei gleicher Umdrehungsanzahl mit einem Verdrillkopf doppelt so lange, wie mit erfindungsgemäss zwei gegenläufig angetriebenen Verdrillköpfen (Voraussetzung: Gleiche Beschleunigungsrampen und Maximaldrehzahlen). Die Leitungen werden erfindungsgemäss gleich schonend behandelt. Es ergibt sich also eine annähernde Halbierung der Verdrillzeit bei gleich schonendem Verdrillprozess im Vergleich zu Verdrilleinrichtungen mit nur einseitigem Verdrillantrieb. Cable support at the second end of the cable. The twisting process thus takes twice as long with the same number of revolutions with a twisting head, as with two counter-rotating twisting heads according to the invention (prerequisite: equal acceleration ramps and maximum speeds). The lines are treated according to the invention gently. Thus, there is an approximate halving of the twisting time with equally gentle twisting process in comparison to twisting devices with only one-sided twisting drive.
In einer bevorzugten Ausführungsform ist den Verdrillköpfen jeweils ein In a preferred embodiment, the twist heads each one
Leitungstransfergreifer zugeordnet, der die jeweiligen Enden der Leitungen an den jeweiligen Verdrillkopf übergibt. Dadurch kann das Einziehen der zu verdrillenden Leitungen in den Bereich zwischen den Verdrillköpfen nacheinander erfolgen. Assigned line transfer gripper, which transfers the respective ends of the lines to the respective twisting head. As a result, the drawing of the lines to be twisted into the region between the twisting heads can take place one after the other.
Während eine bereits eingezogene Leitung durch die Leitungstransfergreifer gehalten wird, erfolgt das Einziehen einer weiteren Leitung, die dann ebenfalls von den Leitungstransfergeifern übernommen wird. Die zu verdrillenden Leitungen werden dann gleichzeitig an die Verdrillköpfe übergeben. Das nacheinander Einziehen der einzelnen Leitungen hat den Vorteil, dass die Fördermittel zum Einziehen der Leitungen nicht doppelt oder mehrfach ausgeführt sein müssen. While a line that has already been fed in is held by the line transfer gripper, another line is pulled in, which is then also taken over by the line transfer fighters. The lines to be twisted are then transferred simultaneously to the twist heads. The successive retraction of the individual lines has the advantage that the conveying means for drawing in the lines need not be made double or multiple.
In einer bevorzugten Ausführungsform wird jeder Verdrillkopf durch einen gesonderten Drehantrieb in Drehung versetzt. Dadurch kann jeder Verdrillkopf je nach Bedarf mit einer eigenen Beschleunigungsrampe beaufschlagt werden. In a preferred embodiment, each twisting head is rotated by a separate rotary drive. As a result, each twisting head can be subjected to its own acceleration ramp as required.
In einer bevorzugten Ausführungsform sind die Drehantriebe der Verdrill köpfe aufeinander synchronisiert. Mit gleichen Drehzahlen bei gegenläufigem In a preferred embodiment, the rotary drives of the twisting heads are synchronized with each other. With same speeds at opposite
Umdrehungssinn kann die Verdrillzeit maximal reduziert, d.h. halbiert werden. The sense of rotation can maximally reduce the twisting time, i. be halved.
In einer bevorzugten Ausführungsform sind die Verdrillköpfe zur Variation ihres gegenseitigen Abstandes relativ zueinander verschiebbar. Zum Zwecke dieser Verschiebbarkeit weisen die Verdrillköpfe eigene Verschiebeantriebe auf. Dadurch können einerseits die Leitungen während des Verdrillens ständig unter Zug gehalten werden, andererseits die Verdrillköpfe unterschiedlichen Leitungslängen angepasst werden. In a preferred embodiment, the twisting heads are displaceable relative to each other for varying their mutual distance. For the purpose of this displacement, the Verdrillköpfe on own displacement drives. As a result, on the one hand, the lines during the twisting constantly kept under train On the other hand, the twist heads are adapted to different cable lengths.
Vorzugsweise sitzt zumindest einer der Verdrillköpfe auf einem verfahrbaren Schlitten, der relativ zur Basis verfahrbar ist. Dies stellt eine besonders einfache und zuverlässige Möglichkeit dar, den gegenseitigen Abstand der Verdrillköpfe in Längsrichtung zu variieren. Preferably, at least one of the Verdrillköpfe sitting on a movable carriage, which is movable relative to the base. This is a particularly simple and reliable way to vary the mutual distance of the twisting heads in the longitudinal direction.
In einer bevorzugten Ausführungsform weist die Verdrillvorrichtung einen In a preferred embodiment, the twisting device has a
Leitungseinzugsgreifer zum Greifen der Leitungen auf und verläuft im Bereich zwischen den Verdrillköpfen eine Führung, entlang derer der Leitungstransfergreifer verfahrbar ist, um die Leitungen in den Bereich zwischen den Verdrillköpfen einzuziehen. Dies stellt eine einfache, platzsparende und zuverlässige Methode dar, die Leitungen entlang ihrer Längserstreckung in die Verdrillvorrichtung zu fördern. Line pick-up gripper for gripping the lines and runs in the area between the twist heads a guide along which the line transfer gripper is moved to feed the lines in the area between the twist heads. This represents a simple, space-saving and reliable method of conveying the lines along their length in the twisting device.
In einer bevorzugten Ausführungsform umfasst die Basis der Verdrillvorrichtung zumindest zwei Teile, wobei ein zweiter Teil der Basis relativ zu einem ersten Teil der Basis entlang einer Richtung verfahrbar ist, die im Wesentlichen parallel zur Verfahrrichtung des Leitungseinzugsgreifers entlang der Führung steht, und wobei die Führung mit dem Leitungseinzugsgreifer auf dem ersten Teil der Basis sitzt und einer der Verdrillköpfe auf dem zweiten Teil der Basis sitzt, und dass zur In a preferred embodiment, the base of the twisting device comprises at least two parts, wherein a second part of the base is movable relative to a first part of the base along a direction that is substantially parallel to the direction of travel of the line pull-in gripper along the guide, and wherein the guide the lead intake gripper is seated on the first part of the base and one of the twisting heads is seated on the second part of the base, and that to
Positionierung des zweiten Teils der Basis relativ zum ersten Teil der Basis der Leitungseinzugsgreifer an den zweiten Teil der Basis ankoppelbar ist, vorzugsweise über eine Wirkschnittstelle (die den Leitungseinzugsgreifer ansonsten in eine geöffnete und/oder geschlossene Stellung bringt), sodass der angekoppelte Positioning of the second part of the base relative to the first part of the base of the line pull-in gripper is coupled to the second part of the base, preferably via an active interface (which otherwise brings the line intake gripper in an open and / or closed position), so that the coupled
Leitungseinzugsgreifer bei einem Verfahren entlang der Führung den zweiten Teil der Basis relativ zum ersten Teil der Basis antreibt und in die gewünschte Position bringt. In the case of a method along the guide, the line pull-in gripper drives the second part of the base relative to the first part of the base and brings it into the desired position.
Durch diese Massnahme kann der Abstand zwischen den Verdrillköpfen bzw. By this measure, the distance between the twisting heads or
zwischen den Leitungstransfergreifern auf einfache Weise verändert werden, z.B. um die Verdrilleinrichtung an die Länge der zu verarbeitenden Leitungen between the line transfer grippers are easily changed, e.g. to the twisting device to the length of the lines to be processed
anzupassen. Einer der Verdrillköpfe wird somit durch den Leitungseinzugsgreifer programmierbar in seine gewünschte Position verfahren.

Die Positionierung übernimmt der Leitungseinzugsgreifer, dessen Ansteuerung ohnedies bereits vorhanden ist. adapt. One of the twisting heads is thus moved programmably by the line intake gripper in its desired position. This coupling function can save a complete positioning axis. The positioning takes over the line intake gripper whose control is already available anyway.
Die Wirkschnittstelle ist dazu ausgebildet, um mit dem Leitungseinzugsgreifer in Wirkverbindung zu treten und diesen in eine geschlossene Stellung oder geöffnete Stellung zu bringen, wenn sich der Leitungseinzugsgreifer im Wirkbereich der Wirkschnittstelle befindet.

The active interface is designed to come into operative connection with the line pull-in gripper and bring it into a closed position or open position when the line pull-in gripper is in the effective range of the active interface. The line pull-in gripper is thus preferably coupled via the same active interface to the movable part of the base, which is also used to open (or close) the line pull-in gripper.

In a preferred embodiment, the Verdrillköpfe each have at least two gripper arms, which can be brought from an open position into a closed, the lines cross-position. The use of gripper arms has proven particularly advantageous. Each twisting head thus also has a gripper drive for opening and closing the gripper.

Die Grundmaschine (bei Schleuniger CrimpCenter genannt) fördert mit einer Leitungszuführeinrichtung (in Fig. 1 durch den links dargestellten Pfeil F angedeutet) zunächst eine Leitung 2 in die Verdrillvorrichtung 1. Vorzugsweise ist diese Leitung 2 an ihrem ersten, rechten Ende bereits mit einem Kontakt bestückt worden, z.B. durch Crimpen. The basic machine (called Schleuniger CrimpCenter) promotes with a Leitungszuführeinrichtung (in Fig. 1 by the arrow F shown on the left) initially a line 2 in the Verdrillvorrichtung 1. Preferably, this line 2 is already equipped at its first, right end with a contact been, for example by crimping.

Hier übernimmt der Gripper closers in the closed, cross position brings) and promotes the Line 2 synchronized with the line feeder (indicated by the arrow F only) of the basic machine to an active interface Y, which includes a gripper opener for opening the line intake gripper 10. Here takes over the
Leitungstransfergreifer X das erste Leitungsende und der Leitungseinzugsgreifer 10 fährt geöffnet zurück, um die nächste Leitung 2 zu übernehmen. Line transfer gripper X the first line end and the line intake gripper 10 moves back to accept the next line 2.
Das nacheilende zweite Leitungsende wird nun ebenfalls mit einem Kontakt bestückt, z.B. durch Crimpen, und dann mit Hilfe von zusätzlichen The trailing second line end is now also equipped with a contact, e.g. by crimping, and then with the help of additional

The movements of the line transfers on the first and second sides of the twisting device 1 are coordinated so that the respective line 2 remains taut with low sag.
Die Leitungstransfergreifer 6, 7 halten nun vorläufig diese erste Leitung 2 an ihren Enden. In der Zwischenzeit wurde im Leitungswechsler der Grundmaschine zur nächsten Leitung gewechselt. Diese wird nun durch die Leitungszuführeinrichtung (Pfeil F) in Richtung Verdrillvorrichtung 1 gefördert. Das voreilende Leitungsende wird mit einem Kontakt versehen. Diese zweite Leitung wird nun analog zur ersten Leitung (wie oben beschrieben) durch den Leitungseinzugsgreifer 10 in die The line transfer grippers 6, 7 now provisionally hold this first line 2 at their ends. In the meantime, the line changer of the basic machine was switched to the next line. This is now conveyed by the line feed device (arrow F) in the direction of twisting device 1. The leading end of the line is provided with a contact. This second line is now analogous to the first line (as described above) through the line intake gripper 10 in the

Während des Verdrillprozesses werden die Leitungen 2 in axialer Richtung mit einer definierten Zugkraft beaufschlagt, so dass das gewünschte Verdrillergebnis erzielt wird und andererseits die Leitungen 2 nicht beschädigt werden. Dann werden die Greiferarme 13, 14 bzw. Spannzangen der Verdrillköpfe 3, 4 geöffnet und das verdrillte, fertige Leitungspaar fällt in eine Ablagewanne (der Übersichtlichkeit wegen nicht dargestellt). Line pair contains no external voltages. During the twisting process, the lines 2 are acted upon in the axial direction with a defined tensile force, so that the desired Verdrillergebnis is achieved and on the other hand, the lines 2 are not damaged. Then the gripper arms 13, 14 or collets of Verdrillköpfe 3, 4 are opened and the twisted, finished pair of wires falls into a storage tray (not shown for clarity).
Fig. 3 ist eine schematische und im Vergleich zur Fig. 1 vereinfachte Darstellung und zeigt eine Ausführungsform der Erfindung, bei der wiederum die Basis 5 der Verdrillvorrichtung 1 zumindest zwei Teile 5a, 5b umfasst. Ein zweiter Teil 5b der Basis 5 ist relativ zu einem ersten Teil 5a der Basis 5 entlang einer Richtung verfahrbar ist, die im Wesentlichen parallel zur Verfahrrichtung des Fig. 3 is a schematic and simplified compared to Fig. 1 representation and shows an embodiment of the invention, in turn, the base 5 of the twisting device 1 comprises at least two parts 5a, 5b. A second part 5b of the base 5 is movable relative to a first part 5a of the base 5 along a direction which is substantially parallel to the direction of travel of the
Leitungseinzugsgreifers 10 entlang der Führung 1 1 steht. Die Führung 1 1 mit dem Leitungseinzugsgreifer 10 sitzt auf dem ersten Teil 5a der Basis 5 und einer der Verdrillköpfe 3 (in Fig. 3 der rechte) sitzt auf dem zweiten Teil 5b der Basis 5. Leitungsseinzugsgreifers 10 along the guide 1 1 stands. The guide 1 1 with the line intake gripper 10 sits on the first part 5 a of the base 5 and one of the twisting heads 3 (in FIG. 3 the right) is seated on the second part 5 b of the base 5.
Um die Verdrillvorrichtung zu Beginn des Verdrillvorganges an die Leitungslänge anzupassen, wird zur Positionierung des zweiten Teils 5b der Basis 5 relativ zum ersten Teil 5a der Basis 5 der Leitungseinzugsgreifer 10 an den zweiten Teil 5b der Basis 5 angekoppelt. Dies erfolgt vorzugsweise über die Wirkschnittstelle Y, an die der Leitungseinzugsgreifer 10 herangefahren wird, sodass die Wirkschnittstelle Y, z.B. durch eine Greif beweg ung, den Leitungseinzugsgreifer 10 fixieren kann. Der angekoppelte Leitungseinzugsgreifer 10 wird nun entlang der Führung 1 1 verfahren und nimmt den zweiten Teil 5b der Basis 5 mit sich mit. Dadurch wird der zweite Teil 5a relativ zum ersten Teil 5a der Basis 5 angetrieben und in die gewünschte In order to adapt the twisting device to the line length at the beginning of the twisting operation, the line 5 is fixed to the second part 5b of the base 5 for positioning the second part 5b of the base 5 relative to the first part 5a of the base 5. This is preferably done via the active interface Y, to which the line pull-in gripper 10 is moved, so that the active interface Y, e.g. by a gripping movement, the line intake gripper 10 can fix. The coupled line intake gripper 10 is now moved along the guide 1 1 and takes the second part 5b of the base 5 with it. As a result, the second part 5a is driven relative to the first part 5a of the base 5 and into the desired
Position gebracht. Anschliessend wird der Leitungseinzugsgreifer 10 wieder abgekoppelt. Eine Bremse 16 ist vorgesehen, um den zweiten Teil der Basis in der gewünschten Position zu arretieren. Position brought. Subsequently, the line intake gripper 10 is decoupled again. A brake 16 is provided to lock the second part of the base in the desired position.
Mit anderen Worten: Zum Einrichten der Maschine auf die gewünschte In other words: to set up the machine to the desired
Leitungslänge muss der verfahrbare Teil 5b neu positioniert werden. Dazu fährt der Leitungseinzugsgreifer 10 ohne die Leitung zur Wirkschnittstelle Y. In dieser Position erfolgt die Ankopplung. Danach wird die Bremse 16 des verfahrbaren Teiles 5b gelöst. Die (indirekte) Ankopplung des Leitungseinzugsgreifer 10 an den zweiten Teil 5b ermöglicht es nun, diesen mit Hilfe der Linearachse des Cable length, the movable part 5b must be repositioned. For this purpose, the line intake gripper 10 moves without the line to the active interface Y. In this position, the coupling takes place. Thereafter, the brake 16 of the movable part 5b is released. The (indirect) coupling of the line pull-in gripper 10 to the second part 5b now makes it possible with the help of the linear axis of the
Leitungseinzugsgreifers 10 in die neue Position zu verfahren. Dort wird die Bremse 16 des zweiten Teiles 5b wieder festgesetzt und der Leitungseinzugsgreifers 10 abgekoppelt. Die Verdrillvorrichtung 1 mit dem Leitungseinzugsgreifer 10 ist nun bereit, neue, zu verdrillende Leitungen einzuziehen. Lead-in gripper 10 to move to the new position. There is the brake 16 of the second part 5 b fixed again and the line intake gripper 10 decoupled. The twisting device 1 with the line intake gripper 10 is now ready to collect new, to be twisted lines.
Im Beispiel der Fig. 3 ist der zweite Teil 5b der Basis unmittelbar auf dem ersten Teil 5a der Basis gelagert. Alternativ könnte der zweite Teil 5b der Basis auch auf der Führung 1 1 gelagert sein und entlang der Führung 1 1 verfahrbar und arretierbar sein. Die Ausdrücke .erster und zweiter Teil der Basis' sind daher im weitesten Sinne zu verstehen. In the example of FIG. 3, the second part 5b of the base is supported directly on the first part 5a of the base.
