Description

Schaltkabel bestehen aus Leitern mit Isolierung, die Adern genannt werden und paarweise zu Dreiern, Vierern oder Fünfern verdrallt und mit einem isolierenden Kabelmantel umgeben sind. Bei der Konfektionierung z. B. zu Steckkabeln besteht nach der Entfernung des Mantels das Problem, die verdrallten Adern automatisch zu entdrallen. Dieser Vorgang, der die Voraussetzung der Automatisierung von weiteren Vorgängen zur Konfektionierung von Schaltkabeln ist, wird bisher von Hand ausgeführt.Switching cables consist of conductors with insulation, which are called wires and twisted in pairs to form three, four or five and surrounded by an insulating cable sheath. When assembling z. B. to plug cables there is the problem after the removal of the jacket to automatically untwist the twisted wires. This process, which is the prerequisite for the automation of further processes for the assembly of switching cables, has so far been carried out by hand.

Der Erfindung liegt die Aufgabe zugrunde, mit einfachen Mitteln ein Verfahren und eine Vorrichtung zum autimatischen Entdrallen von Schaltkabeladern zu schaffen, nachdem der Kabelmantel entfernt ist, an das sich dann weitere Vorgänge zur Automat rung der Konfektionierung von Schaltkabeh ischließen können. Diese Aufgabe wird dadurc jetöst, daß das Kabel an einer angetriebenen Welle so befestigt wird, daß das oder die abgemantelten Enden völlig frei bleiben, daß die Welle zum Rotieren gebracht wird und daß an einer oder mehreren Stellen der Kabelrotierebene die Adern von der Rotierebene durch von einer Ausgangsstellung bewegbare Ablenkmittel abgelenkt und dadurch zu Schwingungen angeregt werden und daß nach der Entdrallzeit die Ablenkmittel in die Ausgangsstellung zurück und die Welle zum Stillstand gebracht werden.The invention has for its object to provide a simple means a method and an apparatus for automatic swirling of switching cable cores after the cable sheath is removed, to which further processes for automatization of the assembly of switching cables can then be closed. This task is now carried out so that the cable is attached to a driven shaft so that the stripped end or ends remain completely free, that the shaft is rotated and that at one or more points on the cable rotation plane the wires from the rotation plane through by deflecting means movable in a starting position are deflected and thereby excited to vibrate and that after the untwisting time the deflecting means are returned to the starting position and the shaft is brought to a standstill.

Mit der Erfindung wird eine dynamische Entdrallmethode geschaffen, die für jeden Schaltkabeltyp anwendbar ist. Alle vorschriftsmäßig verdrallten Adern können damit automatisch entdrallt werden. Für jeden Kabeltyp müssen aber die Entdrallbedingungen optimiert werden. Das Prinzip des dynamischen Entdrallens von Schaltkabeladern nach der Erfindung basiert auf dem Zusammenwirken von drei Faktoren, nämlich Schwingungen, Luftwiderstand und Fliehkraft. Die Fliehkraft hält die Ader gerade, bringt sie zu der Rotierebene zurück und überwindet den Luftwiderstand.The invention provides a dynamic swirl method that can be used for any type of switching cable. All cores that have been twisted according to the regulations can thus be automatically untwisted. The swirl conditions must be optimized for each type of cable. The principle of the dynamic swirling of switching cable cores according to the invention is based on the interaction of three factors, namely vibrations, air resistance and centrifugal force. The centrifugal force keeps the vein straight, brings it back to the rotating plane and overcomes the air resistance.

Eine Vorrichtung zur Durchführung des Verfahrens besteht dann, daß die Welle eines Motors in ein zylindrisches Gehäuse in Achsrichtung hineinragt, daß mit der Welle eine Kabelhalterung verbunden ist und daß als Ablenkmittel in der Nähe der Grund- und Deckfläche des Zylinders um 180° versetzt je ein Profil in Richtung der Kabelrotierebene verschiebbar angeordnet ist. Wenn es sich um zwei Profile handelt, werden die Adern zweimal pro Umdrehung von der Rotierebene abgelenkt und dadurch zu Schwingungen angeregt. Nach bestimmter Zeit werden die beiden Profile wieder in die Ausgangsstellung gebracht und der Motor ausgeschaltet. Die Adern sind dann einwandfrei entdrallt.A device for carrying out the method is that the shaft of a motor protrudes into a cylindrical housing in the axial direction, that a cable holder is connected to the shaft and that as a deflecting means in the vicinity of the base and top surface of the cylinder offset by 180 ° each Profile is slidably arranged in the direction of the cable rotation level. If there are two profiles, the wires are deflected from the rotating plane twice per revolution and thereby excited to vibrate. After a certain time, the two profiles are returned to the starting position and the engine is switched off. The veins are then properly untwisted.

Nach einer weiteren Ausgestaltung der Erfindung weist die Kabelhalterung ein Kabelpositionierrohr auf. Auf diese Weise ist es möglich, beliebige Längen bei der Konfektionierung von Schaltkabeln dynamisch zu entdrallen, da das Mittelteil zwischen den freibleibenden Enden als Schlaufe in das Kabelpositionierrohr eingeschoben werden kann.According to a further embodiment of the invention, the cable holder has a cable positioning tube. In this way, it is possible to dynamically untwist any lengths when assembling switching cables, since the middle part can be inserted as a loop into the cable positioning tube between the free ends.

Um auch das Einschieben des Kabels in das Kabelpositionierrohr automatisch durchführen zu können, ist gegenüber dem Kabelpositionierrohr ein Übergabestempel vorgesehen.In order to be able to automatically insert the cable into the cable positioning tube, a transfer stamp is provided opposite the cable positioning tube.

  • Figur 2 die dazugehörende Vorderansicht,
  • Figur 3 das Prinzip des dynamischen Entdrallens von Schaltkabeladern nach der Erfindung und
  • Figur 4 in schematischer Darstellung einen Aderentdrallautomaten.
The invention is explained on the basis of the figures. It shows
  • FIG. 1 shows an arrangement for dynamically untwisting switching cable cores in a side view,
  • FIG. 2 shows the associated front view,
  • Figure 3 shows the principle of dynamic swirling of switching cable wires according to the invention and

Auf einer Grundplatte 1 ist ein Montageblock 2 vorgesehen, auf dem ein elektrischer Motor 3 angeordnet ist. Auf der Grundplatte 1 sind ferner zwei Halterungen 4 und 5 angebracht, an denen ein zylindrisches Gehäuse 6 befestigt ist. Das Gehäuse 6 und der Motor 3 sind so angeordnet, daß die Motorwelle 7 in dem zylindrischen Gehäuse in Achsrichtung verläuft. Auf der Motorwelle ist in dem Gehäuse eine Kabelhalterung 8 befestigt. Mit 9 und 10 sind Aderentdrallprofile bezeichnet, die über Anordnungen 11 in Richtung der Rotationsebene und wieder in die Ruhelage zurückverschoben werden können. In der Kabelhalterung 8 ist ein Schaltkabel 12 eingelegt, dessen abgemantelte Enden 13 und 14 freibleiben. Mit x ist der Profilanstellwinkel bezeichnet.A mounting block 2, on which an electric motor 3 is arranged, is provided on a base plate 1. On the base plate 1 two brackets 4 and 5 are also attached to which a cylindrical housing 6 is attached. The housing 6 and the motor 3 are arranged so that the motor shaft 7 extends in the axial direction in the cylindrical housing. A cable holder 8 is fastened in the housing on the motor shaft. With 9 and 10 core twist profiles are designated, which can be moved back to the rest position via arrangements 11 in the direction of the plane of rotation and again. In the cable holder 8, a switching cable 12 is inserted, the stripped ends 13 and 14 remain free. The profile angle of attack is designated with x.

Aus der Figur 3 ist zu ersehen, daß bei der Rotation der Motorwelle 7 die freien Enden 13 und 14 des Schaltkabels von den in der Betriebslage befindlichen Profilen 9 und 10 zweimal pro Umdrehung von der Rotierebene abgelenkt und dadurch zu Schwingungen angeregt werden, die das Entdrallen bewirken.It can be seen from FIG. 3 that when the motor shaft 7 rotates, the free ends 13 and 14 of the switching cable are deflected by the profiles 9 and 10 in the operating position twice per revolution from the plane of rotation and are thereby excited to vibrate, which untwists cause.

Nach der Darstellung in der Figur 4 weist der elektrische Motor 3 an der dem Gehäuse zugewandten Seite eine schematisch angedeutete Bremse 15 auf. Die Kabelhalterung ist als Kabelpositionierrohr 16 ausgebildet, die eine Schlaufe 17 des zu entdrallenden Kabels aufnehmen kann. Zur Zuführung des zu entdrallenden Kabels dient ein Rollenförderer 18 mit Kabeltransportrollen 19 und einer kammartigen Kabelanhebevorrichtung 20. Gegenüber dem Kabelpositionierrohr ist ein in Pfeilrichtung verschiebbarer Übergabestempel 21 vorgesehen.According to the representation in FIG. 4, the electric motor 3 has a schematically indicated brake 15 on the side facing the housing. The cable holder is designed as a cable positioning tube 16, which can accommodate a loop 17 of the cable to be untwisted. A roller conveyor 18 with cable transport rollers 19 and a comb-like cable lifting device 20 is used to feed the cable to be untwisted. A transfer stamp 21 which can be displaced in the direction of the arrow is provided opposite the cable positioning tube.
