Description

Die Erfindung bezieht sich auf ein Verfahren zum endseitigen Entdrallen eines insbesondere zweiadrigen Kabels mit gesonderten Adern bzw. Drähten.The invention relates to a method for the end untwisting of a particular two-core cable with separate wires or wires.

Bei der Konfektionierung von Schalt- bzw. Steckkabeln müssen die Adern an den Kabelenden u.a. entdrallt und in die gewünschte Position gebracht werden, um sie im weiteren mit Steckern oder Lötleisten zu verbinden. Hierzu ist es bekannt, die verdrallten Adern des Kabels manuell mit der Hand mehrfach gegen eine Kante zu schlagen und anschließend zwischen den Fingern oder einer Zange auszustreifen und auszurichten. Dieses Entdrall- und Richtverfahren ist umständlich und liefert vor allem für eine maschinelle Weiterverarbeitung ein unbefriedigendes Ergebnis.When assembling switching or plug-in cables, the wires on the Cable ends etc. untwisted and placed in the desired position to them to be further connected with plugs or solder strips. For this purpose, it is known that twisted the wires of the cable manually against an edge several times by hand hit and then strip between fingers or pliers and align. This swirl and straightening process is cumbersome and delivers An unsatisfactory result, especially for mechanical processing.

Aus der DE-A 28 33 563 ist ein Verfahren und eine Vorrichtung zum automatischen Entdrallen von Schaltkabeln bekannt. Hierbei wird das Kabel an einer angetriebenen Welle so befestigt, daß die freien Enden an einer oder mehreren Stellen der Kabelrotierebene durch Ablenkmittel abgelenkt und beim Rotieren der Welle zu Schwingungen angeregt werden, wodurch die Adern entdrallt werden. Das Verfahren ist umständlich und bedingt für eine wirksame Entdrallung relativ hohe Drehzahlen. DE-A 28 33 563 describes a method and a device for automatic Untwist of switching cables known. Here, the cable is driven by a Shaft attached so that the free ends at one or more locations on the Cable rotation plane deflected by deflecting means and when the shaft rotates Vibrations are excited, which untwists the veins. The procedure is cumbersome and requires relatively high speeds for effective swirling.

Weiter zeigt und beschreibt die DE-C 32 24 840 ein Verfahren zum Entdrallen der Adern eines Kabels, wobei die zu entdrallenden Adern auf eine Platte aufgelegt und mit Hilfe einer zu den Adern quer ausgerichteten Profilwalze über den gesamten Bereich der freiliegenden Adern ausgestreift werden und wobei ferner die Profilwalze während des Ausstreifens der Adern in einer zu den Ademenden hin gerichteten Drehrichtung angetrieben und mit definiertem Druck gegen die auf der Platte aufliegenden Adern gedrückt wird. Zwar wird durch die Verwendung der Profilwalze und durch die spezielle Drehrichtung der angetriebenen Profilwalze neben dem Entdrallen gleichzeitig auch ein Ausrichten der Adern bewirkt, jedoch erscheint die für dieses Verfahren angegebene Vorrichtung relativ bauaufwendig.Furthermore, DE-C 32 24 840 shows and describes a method for untwisting the Cores of a cable, the cores to be untwisted placed on a plate and with the help of a profile roller aligned across the entire wire Area of the exposed wires are stripped and also the profile roller during the stripping of the veins in a direction towards the Ademenden Direction of rotation driven and with defined pressure against that on the Plate overlying wires is pressed. By using the Profile roller and the special direction of rotation of the driven profile roller In addition to the untwist, the wires are also aligned, however the device specified for this method appears to be relatively complex.

Weiter sind aus der DE-U 94 08 659 und der US 4 620 573 gattungsfremde Vorrichtungen und Verfahren bekannt zum abschnittsweisen Entdrallen von Adern in entsprechend der gewünschten Ablängung beabstandeten Bereichen eines einstückigen Vorrats-Kabels.Furthermore, from DE-U 94 08 659 and US 4 620 573 non-generic devices and method known for sectioned untwisting of veins in according to the desired cut-off areas of a one-piece Supply cable.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Verfahren so weiterzubilden, daß mit geringem Aufwand ein einwandfreies Kabel-Entdrallen erzielt ist.The invention is based, so the generic method task to further develop that a perfect cable untwisting achieved with little effort is.

Diese Aufgabe ist mit dem Patentanspruch 1 gelöst, und zwar dadurch, daß das nahe einem Endabschnitt drehfest gehaltene Kabel durch eine abschnittsweise rollende Mitnahme des Endabschnittes zwischen relativ zueinander bewegten, elastisch nachgiebig beabstandeten Einrichtungen einer Vorrichtung entdrallt wird.This object is achieved with claim 1, namely in that the near one end section, non-rotatable cables by a section rolling entrainment of the end section between relatively moved, is elastically yieldingly spaced apart devices of a device.

Der Grundgedanke der Erfindung ist, die miteinander verdrillten Adern bzw. Drähte in einem Endabschnitt des Kabels durch eine zwischen relativ zueinander bewegten Einrichtungen ausgelöste, der Steigung der Verdrillung entgegengerichtete Rollbewegung des Kabel-Endabschnittes zu entrollen.The basic idea of the invention is the twisted wires or wires in an end portion of the cable by a moving relative to each other Devices triggered, counter to the slope of the twist Unroll rolling movement of the cable end section.

Der Aufwand des Kabel-Entdrallens bleibt verfahrensmäßig dadurch vorteilhaft gering, daß der Kabel-Endabschnitt zwischen einer fest angeordneten Einrichtung und einer relativ dazu beweglich angeordneten Einrichtung quer zu deren Bewegungsrichtung eingebracht wird, wobei das drehfest gehaltene bzw. in der Drehhalterung fixierte Kabel zum Entdrallen des Endabschnittes mitbewegt wird.In terms of the process, the effort of cable swirling remains advantageous low that the cable end section between a fixed device and a device movably arranged relative thereto, transverse to the direction of its movement is introduced, the non-rotatably held or in the rotary holder fixed cable is also moved to untwist the end section.

Beim Entdrallen eines insbesondere zweiadrigen Kabels kann der Aufwand vorteilhafterweise weiter dadurch verringert werden, daß das Kabel während des Durchlaufes zwischen den Einrichtungen von Hand drehfest gehalten wird.The effort can be advantageous when untwisting an in particular two-core cable can be further reduced in that the cable during the passage between the devices is held by hand.

In weiteren Ansprüchen ist eine mit geringem Aufwand erzielbare Vorrichtung zur Durchführung des Verfahrens beschrieben.In further claims a device can be achieved with little effort Implementation of the procedure described.

Die Erfindung ist anhand einer in der Zeichnung schematisch dargestellten Vorrichtung zur Durchführung des Verfahrens zum endseitigen Entdrallen eines insbesondere zweiadrigen Kabels mit gesonderten Adern bzw. Drähten beschrieben.The invention is based on a device shown schematically in the drawing to carry out the method for untwisting an end in particular described two-core cable with separate wires or wires.

Eine Vorrichtung 1 weist in einem Gestell 2 eine fest angeordnete Einrichtung 3 und eine relativ dazu beweglich angeordnete Einrichtung 4 auf. Die fest angeordnete Einrichtung 3 umfaßt eine federelastisch nachgiebig angeordnete, biegesteife Rollplatte 5 mit einer beispielsweise aus einem Elastomer gebildeten Reibauflage 6. Die andere Einrichtung 4 umfaßt ein über zwei Rollen 7, 8 umlaufendes Band 9 mit einer ebenfalls aus einem Elastomer gebildeten Reibauflage 10. Das Band 9 läuft mit seiner Rückseite über eine zwischen den Rollen 7, 8 angeordnete Abstützung 11. Die Vorrichtung 1 ist weiter so gestaltet, daß die Rollplatte 5 in ihrem Abstand zum Band 9 entsprechend den Durchmessern der Adern bzw. Drähte eines verdrillten Kabels einstellbar ausgebildet ist.A device 1 has a fixed arrangement 3 in a frame 2 and a device 4 arranged movably relative thereto. The fixed one Device 3 comprises a resiliently arranged, rigid Roll plate 5 with a friction pad formed, for example, from an elastomer 6. The other device 4 comprises a belt 9 rotating over two rollers 7, 8 with a friction pad 10 also formed from an elastomer. The belt 9 runs with its back over a arranged between the rollers 7, 8 support 11. The device 1 is further designed so that the rolling plate 5 in its Distance to band 9 according to the diameters of the wires or wires a twisted cable is adjustable.

Die Vorrichtung 1 dient zur Durchführung des Verfahrens zum endseitigen Entdrallen eines insbesondere zweiadrigen Kabels 12 mit gesonderten Adern bzw. Drähten 13, 14, wobei das nahe einem Endabschnitt 15 vorzugsweise von Hand drehfest gehaltene Kabel 12 durch eine rollende Mitnahme des Endabschnittes 15 zwischen der fest angeordneten Rollplatte 5 und dem umlaufenden Band 9 entdrallt wird. Das Kabel 12 wird mit seinem verdrillten Endabschnitt 15 bei 16 quer zur Bewegungsrichtung 17 des Bandes 9 zugeführt, wobei die Bewegungsrichtung 17 des Bandes 9 der Steigung der Verdrillung der Drähte 13, 14 entgegengerichtet gewählt ist. Durch die Reibauflage 6 der Rollplatte 5 und durch die Reibauflage 10 des Bandes 9 wird das bei 16 quer zum Band 9 eingebrachte Kabel 12 erfaßt und durch die rollende Mitnahme zwischen den beiden Einrichtungen 3 und 4 entdrallt, d.h. die zunächst miteinander verdrillten Adern 13 und 14 sind entsprechend dem vorgewählten Endabschnitt 15 am Ende des Durchlaufes durch die Vorrichtung 1 voneinander entfernt und überraschend weitgehend gerad gerichtet.The device 1 is used to carry out the method for untwisting at the end a particularly two-wire cable 12 with separate wires or wires 13, 14, the near an end portion 15 preferably rotatably by hand held cable 12 by a rolling entrainment of the end portion 15 between the fixed roller plate 5 and the revolving belt 9 swirled becomes. The cable 12 is with its twisted end section 15 at 16 transverse to the direction of movement 17 of the belt 9 fed, the direction of movement 17th of the band 9 of the slope of the twisting of the wires 13, 14 opposed is selected. Through the friction pad 6 of the roller plate 5 and through the friction pad 10 of the band 9, the cable 12 introduced at 16 across the band 9 is detected and swirled by the rolling entrainment between the two devices 3 and 4, i.e. the wires 13 and 14 which are initially twisted together are corresponding to the preselected end section 15 at the end of the passage through the device 1 apart and surprisingly largely straight.

Der entsprechend dem Durchmesser des jeweiligen Drahtes 13, 14 des Kabels 12 gewählte Abstand zwischen der Rollplatte 5 und dem Band 9 einerseits und der Härte der Abfederung der Rollplatte 5 andererseits erklärt die vorteilhafte Geradrichtung der voneinander entfernten Adern bzw. Drähte 13, 14 im entdrallten Endabschnitt 15'.Which corresponds to the diameter of the respective wire 13, 14 of the cable 12 selected distance between the roller plate 5 and the belt 9 on the one hand and the Hardness of the cushioning of the roller plate 5, on the other hand, explains the advantageous straight direction the twisted wires or wires 13, 14 in the untwisted End section 15 '.

Das erfindungsgemäße Verfahren bietet somit neben dem mit geringem Aufwand vorteilhaft durchführen Entdrallen eines insbesondere zweiadrigen Kabels zusätzlich den Vorteil weitgehend gerad gerichteter, voneinander entfernter Adern bzw. Drähte 13, 14 im entdrallten Endabschnitt 15'.In addition to that, the method according to the invention offers little effort advantageously perform an untwist of a two-core cable in particular the advantage of largely straight, spaced cores or Wires 13, 14 in the untwisted end section 15 '.
