Abstract

With this improvement to the device for feeding a cable into an automatic cable processor, it is possible to move normal cables and cables of reduced wall thickness (18) at high speeds through the drive surfaces (3.1,8.1) of two drive belts (3,8), applied against each other, of two belt drives (1,2). By the separation of a drive roller (12) driven synchronously with the belt drives (1,2) from the measurement drive roller (21) of the cable length measurement device (22), it is made possible to vary the diameter and hence the peripheral speed of this drive roller (12). Thus a tension can be constantly applied to the cable (18) between the belt drives (1,2) and the drive roller (12) corresponding to the running direction of the cable (18), preventing piling up of the cable in this region and a possible lateral emergence of the cable from the belt drives (1,2), and ensuring an accurate length measurement for the cable sections. <IMAGE>

Description

Die Erfindung betrifft eine Verbesserung an der Einrichtung zum Zubringen eines Kabels in einen Kabel-Verarbeitungsautomaten, mit zwei gegeneinandergerichteten Riementrieben und einer die vorgegebene Länge eines Kabelabschnittes messenden Kabel-Längenmesseinrichtung, wobei ein erster Riementrieb mit zwei Umlenkrollen, mindestens einer Druckrolle und einem Treibriemen fest angeordnet ist und ein zweiter Riementrieb eine feste, antreibbare Umlenkrolle und auf einer senkrecht zur Zubringrichtung des Kabels parallel verschiebbar gelagerten Tragplatte angeordnete, aus Umlenkrollen, Druckrollen und dem Treibriemen bestehende Anpresseinrichtung aufweist, welche durch eine Kraft den Treibriemen des zweiten Riementriebes gegen den Treibriemen des ersten Riementriebes, bzw. gegen das zwischen den beiden Treibriemen eingelegte Kabel drückt und das Kabel gegen den Kabel-Verarbeitungsautomaten antreibt und das angetriebene Kabel seinerseits, ausserhalb des fest angeordneten Riementriebes eine Messtreibrolle der Kabel-Längenmesseinrichtung mittreibt.The invention relates to an improvement in the device for feeding a cable into a cable processing machine, with two belt drives directed against one another and a cable length measuring device measuring the predetermined length of a cable section, a first belt drive with two deflection rollers, at least one pressure roller and a drive belt being arranged in a fixed manner is and a second belt drive has a fixed, drivable deflection roller and on a support plate, which is mounted parallel to the feed direction of the cable and can be displaced in parallel and consists of deflection rollers, pressure rollers and the drive belt, which force the drive belt of the second belt drive against the drive belt of the first belt drive , or presses against the cable inserted between the two drive belts and drives the cable against the automatic cable processing machine and the driven cable in turn, a meter outside the fixed belt drive driving roller of the cable length measuring device.

Eine solche Einrichtung zum Transportieren eines Kabels in einen Kabelverarbeitungsautomaten ist in der vorausgehenden EP-Anmeldung Nr. 90114421.2 der gleichen Anmelderin beschrieben. Bei dieser Einrichtung wird der Draht zwischen zwei gegeneinandergerichteten Riementrieben eingeklemmt und durch die beiden Riemen transportiert. Ein Riementrieb ist stationär eingebaut und besitzt eine angetriebene Messtreibrolle, eine Umlenkrolle und eine Anzahl Druckrollen kleineren Durchmessers, welche zusammen mit der mit der Umlenkrolle und dem Treibriemen eine in einer Ebene liegende Antriebsfläche für das Kabel bilden. Der andere Riementrieb ist verschiebbar gelagert und besteht aus einer auf einer fest angeordneten Achse drehbar gelagerten Antriebsrolle und einer Anzahl auf einer verschiebbar gelagerten Platte angeordneten Umlenk- und Druckrollen, welche mit der Lage der Rollen des stationären Riementriebes übereinstimmen und mit dem Treibriemen eine parallel zur Antriebsfläche des stationären Riementriebes verlaufende Antriebsfläche bilden und einer Spannrolle zum automatischen Spannen des Treibriemens. Die Antriebsfläche des verschiebbar gelagerten Riementriebes überragt die Antriebsfläche des stationären Riementriebes und bildet damit, zusammen mit dem angetriebenen Kabel eine Antriebsfläche für die Messtreibrolle der Kabel-Längenmesseinrichtung.Such a device for transporting a cable into an automatic cable processing machine is described in the previous EP application No. 90114421.2 by the same applicant. In this device, the wire is clamped between two belt drives facing each other and transported by the two belts. A belt drive is installed stationary and has a driven measuring drive roller, a deflection roller and a number of pressure rollers of smaller diameter, which together with the one with the deflection roller and the drive belt lie in one plane Form the drive surface for the cable. The other belt drive is slidably mounted and consists of a drive roller rotatably mounted on a fixed axis and a number of deflection and pressure rollers arranged on a slidably mounted plate, which correspond to the position of the rollers of the stationary belt drive and with the drive belt parallel to the drive surface of the stationary belt drive running drive surface and a tension roller for automatic tensioning of the drive belt. The drive surface of the displaceably mounted belt drive projects beyond the drive surface of the stationary belt drive and thus forms, together with the driven cable, a drive surface for the measuring drive roller of the cable length measuring device.

Ein Nachteil dieser Einrichtung liegt darin, dass der einwandfreie Lauf des Kabels auf der verhältnismässig langen Strecke zwischen den beiden Riementrieben schwer kontrollierbar ist, und dass sich zwischen den beiden Riementrieben zum Antreiben des Kabels und der vom Kabel angetriebenen Messtreibrolle der Kabel-Längenmesseinrichtung unterschiedliche Schlupfverhältnisse ergeben, derart, dass sich das Kabel zwischen dem Austritt aus den Riementrieben und der nachfolgenden Kabelführung aufstauen kann. Dabei kann es vorkommen, dass das Kabel seitlich aus der Zuführeinrichtung austritt und diese unkontrolliert verlässt und vor dem Eintritt in den Kabel-Verarbeitungsautomaten ein Kabel-Wirrwarr entsteht.A disadvantage of this device is that the proper running of the cable over the relatively long distance between the two belt drives is difficult to control, and that there are different slip ratios between the two belt drives for driving the cable and the measuring drive roller of the cable length measuring device driven by the cable , such that the cable can drift between the exit from the belt and the subsequent cable guide. It can happen that the cable emerges from the side of the feed device and leaves it in an uncontrolled manner and there is a tangle of cables before entering the cable processing machines.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Verbesserung der Einrichtung zum Zubringen eines Kabels in einen Kabel-Verarbeitungsautomaten vorzuschlagen, durch welche ein einwandfreier Lauf des Kabels zwischen den beiden Riementrieben gewährleistet ist und ein Aufstauen des angetriebenen Kabels zwischen dem Austritt aus den Riementrieben und der nachfolgenden Kabelführung oder ein seitliches Austreten des Kabels aus der Zuführeinrichtung verhindert wird.The invention is therefore based on the object of proposing an improvement in the device for feeding a cable into a cable processing machine, by means of which a perfect running of the cable between the two belt drives is ensured and a build-up of the driven cable between the exit from the belt drives and the subsequent cable routing or a lateral escape of the cable from the feed device is prevented.

Diese Aufgabe wird durch die im Anspruch 1 gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in claim 1.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass eine separat angetriebene und vom Treibriemen unabhängige Antriebsrolle für den Antrieb der Kabel-Längenmesseinrichtung im Durchmesser variiert werden kann, wodurch je nach der Bewegungsrichtung des Kabels mit einer grösseren oder einer kleineren Antriebsrolle stets eine das Kabel streckende Spannung im Kabel zwischen den Riementrieben und der angetriebenen Messtreibrolle zur Kabel-Längenmesseinrichtung erreicht werden kann. Zusammen mit zusätzlichen Kabelführungen zwischen den Riementrieben und der Messtreibrolle und zwischen der Messtreibrolle und der Klemmvorrichtung wird ein Aufstauen oder ein Austreten des Kabels aus der Kabelzuführeinrichtung verhindert. Damit wird auch die gnaue Funktion der Kabel-Längenmesseinrichtung gewährleistet.The advantages achieved by the invention can be seen essentially in the fact that a separately driven drive roller independent of the drive belt for driving the cable length measuring device can be varied in diameter, so that depending on the direction of movement of the cable with a larger or a smaller drive roller a tension stretching the cable in the cable between the belt drives and the driven measuring drive roller to the cable length measuring device can be achieved. Together with additional cable guides between the belt drives and the measuring drive roller and between the measurement drive roller and the clamping device, the cable is prevented from being jammed or escaping from the cable feed device. This also ensures that the cable length measuring device functions correctly.

In den Fig. 1, 2, 3 und 4 ist mit 1 ein stationärer Riementrieb bezeichnet. Der stationäre Riementrieb 1 weist einen Treibriemen 3, eine erste, angetriebene Umlenkrolle 4, eine zweite Umlenkrolle 5 und beispielsweise drei Druckrollen 6 auf. Die zweite Umlenkrolle 5 und die Druckrollen 6 weisen nicht gleiche Durchmesser auf, sind aber so angeordnet, dass sie zusammen mit dem Treibriemen 3 eine in einer Ebene liegende Antriebsfläche 3.1 bilden, wobei die Umlenkrolle 4, welche mit einer auf Kugellagern gelagerten Welle 4.1 fest verbunden ist, gegenüber den Druckrollen 6 so angeordnet ist, dass der Treibriemen 3 mit einer Neigung 3.2 in die Antriebsfläche 3.1 einläuft. Auf der gleichen Welle 4.1 ist als Antriebsrad beispielsweise ein Zahnrad 7 fest angeordnet. Gegenüber dem stationären Riementrieb 1 ist ein senkrecht zu der Bewegungsrichtung des Kabels verschiebbar gelagerter Riementrieb 2 vorgesehen, bestehend aus einem Treibriemen 8, einer auf Kugellagern drehbar aber unverschiebbar angeordneten Welle 9.1, welche auf einem Ende mit einer Umlenkrolle 9 und auf dem anderen Ende mit einem angetriebenen Zahnrad 23 fest verbunden ist, sowie einer senkrecht zur Bewegungsrichtung des Kabels verschiebbar gelagerten Tragplatte 10. Die verschiebbar gelagerte Tragplatte 10 des verschiebbar gelagerten Riementriebes 2 ist auf zwei senkrecht zur Antriebsfläche 3.1 fest auf einem Tragrahmen des stationären Riementriebes 1 parallel angeordneten Führungszapfen 11 gleitend geführt. Die Tragplatte 10 nimmt eine Umlenkrolle 13, beispielsweise drei kleinere Druckrollen 14 und eine Ausgleichsrolle 15 auf. Die Umlenkrolle 13 und die Druckrollen 14 sind auf Kugellagern gelagert, welche auf fest mit der Tragplatte 10 verbundenen Achsen ruhen und so angeordnet, dass sie zusammen mit dem Treibriemen 8 stets eine in einer Ebene liegende und parallel zur Antriebsfläche 3.1 des festen Riementriebes 1 verlaufende Antriebsfläche 8.1 bilden. Die Tragplatte 10 wird mit Hilfe einer Antriebseinheit, beispielsweise einer Kolben-Zylindereinheit 24, auf den Führungszapfen 11 gleitend gegen den stationären Riementrieb 1 bewegt, wobei die Antriebsfläche 8.1 des verschiebbar gelagerten Riementriebes 2 parallel gegen die Antriebsfläche 3.1 des stationären Riementriebes 1 drückt. Die Ausgleichsrolle 15 dient dazu, den Treibriemen 8 des verschiebbar gelagerten Riementriebes 2 auch in der ausgefahrenen Ruhestellung unter Spannung zu halten, bzw. eine Längenreserve des Treibriemens 8, welche für die Verschiebung der Tragplatte 10 mit den Druckrollen 14 und der Umlenkrolle 13 in die Arbeitsstellung benötigt wird, in der ausgefahrenen Ruhestellung aufzunehmen. Zwischen den Antriebsflächen 3.1, 8.1 der beiden aufeinander abwälzenden Treibriemen 3, 8 ist ein Draht oder Kabel 18 eingelegt. Die Druckrollen 6 und die Umlenkrolle 5 des stationären Riementriebes 1 liegen walzenartig gegenüber den Druckrollen 14 und der Umlenkrolle 13 des verschiebbar gelagerten Riementriebes 2, so dass der Draht oder das Kabel 18 durch die beiden in gleicher Richtung bewegten Trums der gegenläufig angetriebenen Riementriebe 1, 2 mitbewegt wird. Auf der Kabel-Zuführseite 16 wird das Kabel 18 durch eine in der Achsrichtung des zugeführten Kabels 18 verschiebbar gelagerte Klemm-Spannvorrichtung 19 und auf der Kabel-Austrittseite 17 durch eine zusätzliche Kabelführung 32 und eine Klemmvorrichtung 20 hindurchgeführt. Neben der Umlenkrolle 5 des stationären Riementriebes 1 ist eine einzelne Antriebsrolle 12 ebenfalls stationär angeordnet, welche mit einer gegenüberliegenden Messtreibrolle 21 einer Kabel-Längenmesseinrichtung 22 zusammenarbeitet. Die Antriebsrolle 12 ist fest verbunden mit einem Ende einer auf Kugellagern im Tragrahmen des stationären Riementriebes 1 gelagerten Welle 12.1 auf deren anderem Ende ein Zahnrad 26 ebenfalls fest verbunden ist. Die Kabel-Längenmesseinrichtung 22 ist senkrecht zu der Bewegungsrichtung des Kabels verschiebbar gelagert und mit einer justierbaren Zustellung ausgerüstet, die ein Mitdrehen der Messtreibrolle 21 durch das von den Riementrieben 1, 2 bewegte Kabel 18 ermöglicht, aber ein Mitdrehen bei fehlendem Kabel 18 verhindert. Im Zwischenraum zwischen den Riementrieben 1, 2 und der Kabel-Längenmesseinrichtung 22 ist am Tragrahmen des stationären Riementriebes 1 die zusätzliche Kabelführung 32 angeordnet. Ein endloser doppelseitiger Zahnriemen 30, von einem Antriebsmotor 31 über ein Zahnrad 23 angetrieben, treibt über die Zahnräder 7 und 23 die beiden Riementriebe 1, 2 und über das Zahnrad 26 die Antriebsrolle 12 an. Um die gewünschte Drehrichtung und einen genügenden Umschlingungswinkel für jedes einzelne Zahnrad zu erhalten sind zusätzlich Umlenkzahnräder 28, 29 erforderlich.1, 2, 3 and 4, 1 denotes a stationary belt drive. The stationary belt drive 1 has a drive belt 3 , a first, driven deflection roller 4 , a second deflection roller 5 and, for example, three pressure rollers 6 . The second deflection roller 5 and the pressure rollers 6 do not have the same diameter, but are arranged such that they form a drive surface 3.1 lying in one plane together with the drive belt 3 , the deflection roller 4 , which is fixedly connected to a shaft 4.1 mounted on ball bearings is arranged opposite the pressure rollers 6 in such a way that the drive belt 3 runs into the drive surface 3.1 with an inclination 3.2 . A gear 7 , for example, is fixedly arranged on the same shaft 4.1 as the drive wheel. Compared to the stationary belt drive 1 , a belt drive 2 is provided which is displaceable perpendicular to the direction of movement of the cable, consisting of a drive belt 8 , a shaft 9.1 which is rotatably but non-displaceably arranged on ball bearings and which has a deflection roller 9 on one end and a one on the other end driven gear 23 is fixedly connected, and a support plate 10 mounted displaceably perpendicular to the direction of movement of the cable. The displaceably mounted support plate 10 of the displaceably mounted belt drive 2 is slidably guided on two guide pins 11 arranged parallel to the drive surface 3.1 on a support frame of the stationary belt drive 1 in parallel. The support plate 10 receives a deflection roller 13 , for example three smaller pressure rollers 14 and a compensating roller 15 . The deflection roller 13 and the pressure rollers 14 are mounted on ball bearings, which rest on axles firmly connected to the support plate 10 , and are arranged such that, together with the drive belt 8, they always have a drive surface lying in one plane and parallel to the drive surface 3.1 of the fixed belt drive 1 8.1 form. The support plate 10 is with the help a drive unit, for example a piston-cylinder unit 24 , slidably moves on the guide pin 11 against the stationary belt drive 1 , the drive surface 8.1 of the displaceably mounted belt drive 2 pressing in parallel against the drive surface 3.1 of the stationary belt drive 1 . The compensating roller 15 serves to keep the drive belt 8 of the displaceably mounted belt drive 2 under tension even in the extended rest position, or a length reserve of the drive belt 8 , which is used for the displacement of the support plate 10 with the pressure rollers 14 and the deflection roller 13 into the working position is needed to record in the extended rest position. A wire or cable 18 is inserted between the drive surfaces 3.1 , 8.1 of the two drive belts 3, 8 which roll on one another. The pressure rollers 6 and the deflection roller 5 of the stationary belt drive 1 lie in a roller-like manner with respect to the pressure rollers 14 and the deflection roller 13 of the displaceably mounted belt drive 2 , so that the wire or the cable 18 through the two strands of the oppositely driven belt drives 1, 2 moved in the same direction is moved. On the cable feed side 16 , the cable 18 is guided through a clamping tensioning device 19 which is displaceably mounted in the axial direction of the supplied cable 18 and on the cable exit side 17 through an additional cable guide 32 and a clamping device 20 . In addition to the deflection roller 5 of the stationary belt drive 1 , a single drive roller 12 is also arranged in a stationary manner, which cooperates with an opposite measuring drive roller 21 of a cable length measuring device 22 . The drive roller 12 is fixedly connected to one end of a shaft 12.1 mounted on ball bearings in the support frame of the stationary belt drive 1 , on the other end of which a gearwheel 26 is also fixedly connected. The cable length measuring device 22 is mounted displaceably perpendicular to the direction of movement of the cable and is equipped with an adjustable infeed which prevents the measuring drive roller 21 from rotating as well enables cables 18 moved by the belt drives 1 , 2 , but prevents rotation when the cable 18 is missing. In the space between the belt drives 1 , 2 and the cable length measuring device 22 , the additional cable guide 32 is arranged on the support frame of the stationary belt drive 1 . An endless double-sided toothed belt 30 , driven by a drive motor 31 via a toothed wheel 23 , drives the two belt drives 1 , 2 via the toothed wheels 7 and 23 and the drive roller 12 via the toothed wheel 26 . In order to obtain the desired direction of rotation and a sufficient wrap angle for each individual gear wheel, additional deflection gears 28 , 29 are required.

Die vorstehend beschriebene Einrichtung zum Zubringen eines elektrischen Leiters oder eines Kabels 18 in einen Kabel-Verarbeitungsautomaten arbeitet wie folgt: Ein ausgewähltes Kabel 18 wird im ausgefahrenen Ruhestand des verschiebbar gelagerten Riementriebes 2 bei nicht angetriebenen Treibriemen 3, 8 manuell durch die Klemm-Spannvorrichtung 19, zwischen den Treibriemen 3, 8 der beiden Riementriebe 1, 2, durch die zusätzliche Kabelführung 32, zwischen der Antriebsrolle 12 und der Messtreibrolle 21 der Kabel-Längenmesseinrichtung 22 und durch die Klemmvorrichtung 20 hindurchgeführt. Das Kabel 18 wird von der Klemm-Spannvorrichtung 19 und von der Klemmvorrichtung 20 geklemmt, mit der Klemm-Spannvorrichtung 19 gespannt und der verschiebbar gelagerte Riementrieb 2 mit Hilfe der pneumatischen Kolben-Zylindereinheit 24 zugestellt, bis das eingezogene Kabel 18 zwischen den beiden Antriebsflächen 3.1, 8.1 der Riementriebe 1, 2 festgehalten ist. Gleichzeitig wird auch die Messtreibrolle 21 der Kabel-Längenmesseinrichtung 22 an das Kabel 18 angestossen. Nach diesen Manipulationen werden die Klemmvorrichtung 20 und die Klemm-Spannvorrichtung 19 gelöst und gleichzeitig der Antrieb für die Riementriebe eingeschaltet, wobei der doppelseitige Zahnriemen 30 über das Zahnrad 23, durch den Antriebsmotor 31 angetrieben wird. Beide Riementriebe 1, 2 bewegen das Kabel 18 mit gleicher Geschwindigkeit um eine erste vorgewählte und von der Kabel-Längenmesseinrichtung 22 überwachte Minimaldistanz vorwärts in eine nicht dargestellte Schneidvorrichtung und halten an, für einen ersten Schnitt durch die Schneidvorrichtung. Der Kabelzubringer ist damit bereit für den automatischen Betrieb, bei welchem die beiden angetriebenen Riementriebe 1, 2 das Kabel 18 taktweise vorwärtsbewegen. Die Messtreibrolle 21 der Kabel-Längenmesseinrichtung 22 wird vom vorwärtsbewegten Kabel angetrieben, bis die vorgewählte Länge für den jeweiligen Kabelabschnitt erreicht ist und die Kabel-Längenmesseinrichtung 22 jedesmal den Impuls zum Stillsetzen der Riementriebe gibt, bzw. das Steuerprogramm zum Festhalten des Kabels und zum Betätigen der ausserhalb der Einrichtung zum Zubringen eines Kabels angeordneten und nicht dargestellten und nicht direkt zum Erfindungsgegenstand gehörige Einrichtungen des Kabel-Verarbeitungsautomaten, wie das Schneidmesser, die Abisoliereinrichtung, die Crimppressen etc. einsetzt.
Beim Zustellen des verschiebbar gelagerten Riementriebes 2 wird die verschiebbar gelagerte Tragplatte 10 zusammen mit der Umlenkrolle 13, den Druckrollen 14 und der Ausgleichsrolle 15, durch die beiden Führungszapfen 11 parallel geführt. Dabei verschiebt sich die gebildete Antriebsfläche 8.1 des Treibriemens 8 parallel gegen die Antriebsfläche 3.1 des Treibriemens 3 des stationären Riementriebes 1. Zwischen der fest angeordneten Umlenkrolle 9, welche ihre Lage stets beibehält, und der ersten Druckrolle 14 entsteht ein grösserer Achsabstand, so dass der Treibriemen 8 auch beim verschiebbaren Riementrieb 2 in der eingefahrenen Arbeitsstellung (Fig. 2) mit einer Neigung 8.2 in die Antriebsfläche 8.1 einläuft. Innerhalb der beiden Neigungen 3.2, 8.2 führt eine stationäre, konisch zulaufende Führungsbüchse 25 das Kabel 18 exakt zwischen die Antriebsflächen 3.1, 8.1 der Riementriebe 1, 2. Beim Verschieben der Antriebsfläche 8.1 des verschiebbar gelagerten Riementriebes 2 gegen die Antriebsfläche 3.1 des stationären Riementriebes 1 wird der untere Riementrum des Treibriemens 8 gespannt, während gleichzeitig der obere Riementrum durch das Mitbewegen der Ausgleichsrolle 15 entlastet wird. Die Ausgleichsrolle 15 bewirkt, dass der verschiebbar gelagerte Riementrieb 2 trotz feststehender, angetriebener Umlenkrolle 9 in jeder Stellung zwischen ausgefahrener Ruhestellung (Fig.1) und der eingefahrenen Arbeitsstellung (Fig. 2) ungefähr die gleiche Riemenspannung aufweist. Beide Treibriemen 3, 8 sind durch je eine nicht dargestellte Exzenter-Spannvorrichtung zusätzlich spannbar, um Längenungenauigkeiten der endlosen Treibriemen 3, 8 auszugleichen.
Die Messtreibrolle 21 der Kabel-Längenmesseinrichtung 22 kann zusätzlich einen limitierten Weg senkrecht zur Bewegungsrichtung des Kabels 18 ausführen und wird durch die Kraft von Federn an das Kabel 18 angedrückt und später durch das bewegte Kabel 18 angetrieben. Bei fehlendem Kabel 18 berührt aber die Messtreibrolle 21 die Antriebsrolle 12 nicht und die Kabel-Längenmesseinrichtung 22 wird auch nicht angetrieben. Für das beschriebene Ausführungsbeispiel wird der Durchmesser der Antriebsrolle 12 zur Messtreibrolle 21 leicht grösser gewählt, derart, dass die Umfangsgeschwindigkeit der Antriebsrolle 12 leicht grösser ist als die Umfangsgeschwindigkeit der Treibriemen 3, 8. Dadurch entsteht im Kabel 18 zwischen dem Austritt aus den Riementrieben 1, 2 und der Kabel-Längenmesseinrichtung 22 stets eine Zugspannung. Mit dieser Zugspannung und der zusätzlichen Kabelführung 32 wird ein Kabelstau vor und nach der Kabel-Längenmesseinrichtung 22 verhindert.
Zur Überwachung einer abnormalen Kabelzugkraft, bzw. um Beschädigungen der laufenden Treibriemen bei blockiertem Kabel zu verhindern, ist eine vergleichende Schlupfmessvorrichtung zwischen den Treibriemen und der Messtreibrolle der Kabel-Längenmesseinrichtung vorgesehen. Sobald bei angetriebenen und bewegten Treibriemen keine Drehbewegung der Messtreibrolle erfolgt, wird der Antrieb der Riementriebe unterbrochen.
Die Kontrolle eines blockierten Kabels wäre auch durch die Überwachung des Drehmomentes des Antriebsmotors der Riementriebe möglich, indem bei einer abnormalen Zunahme des Motordrehmomentes, durch die Zunahme der Reibung zwischen den Riementrieben und einem blockierten Kabel, der Antriebsmotor abgeschaltet wird.
The above-described device for feeding an electrical conductor or a cable 18 into a cable processing machine works as follows: A selected cable 18 is manually moved out of the retractable belt drive 2 with the drive belt 3 , 8 not driven by the clamping tensioning device 19 , between the drive belts 3 , 8 of the two belt drives 1 , 2 , through the additional cable guide 32 , between the drive roller 12 and the measuring drive roller 21 of the cable length measuring device 22 and through the clamping device 20 . The cable 18 is clamped by the clamping tensioning device 19 and by the clamping device 20 , tensioned with the clamping tensioning device 19, and the displaceably mounted belt drive 2 is delivered by means of the pneumatic piston-cylinder unit 24 until the retracted cable 18 between the two drive surfaces 3 . 1 , 8 . 1 of the belt drives 1 , 2 is held. At the same time, the measuring drive roller 21 of the cable length measuring device 22 is also pushed onto the cable 18 . After these manipulations, the clamping device 20 and the clamping tensioning device 19 are released and at the same time the drive for the belt drives is switched on, the double-sided toothed belt 30 being driven by the drive motor 31 via the toothed wheel 23 . Both Belt drives 1 , 2 move the cable 18 at the same speed forward by a first preselected minimum distance, monitored by the cable length measuring device 22 , into a cutting device (not shown) and stop for a first cut through the cutting device. The cable feeder is thus ready for automatic operation, in which the two driven belt drives 1 , 2 move the cable 18 forward in cycles. The measuring drive roller 21 of the cable length measuring device 22 is driven by the advancing cable until the preselected length for the respective cable section is reached and the cable length measuring device 22 gives the impulse to stop the belt drives or the control program to hold the cable and to actuate it the devices of the cable processing machine, such as the cutting knife, the stripping device, the crimping presses, etc., which are arranged outside the device for feeding a cable and are not shown and do not directly belong to the subject matter of the invention.
When the displaceably mounted belt drive 2 is delivered, the displaceably mounted support plate 10, together with the deflection roller 13 , the pressure rollers 14 and the compensating roller 15 , are guided in parallel by the two guide pins 11 . The drive surface 8 formed thereby shifts. 1 of the drive belt 8 in parallel against the drive surface 3 . 1 of the drive belt 3 of the stationary belt drive 1 . There is a larger center distance between the fixed deflection roller 9 , which always maintains its position, and the first pressure roller 14 , so that the drive belt 8 also with the displaceable belt drive 2 in the retracted working position (FIG. 2) with an inclination 8.2 in the drive surface 8 . 1 arrives. Within the two inclinations 3 . 2 , 8 . 2 , a stationary, tapered guide bush 25 guides the cable 18 exactly between the drive surfaces 3 . 1 , 8 . 1 of the belt drives 1 , 2 . At the Moving the drive surface 8 . 1 of the slidably mounted belt drive 2 against the drive surface 3 . 1 of the stationary belt drive 1 , the lower belt drum of the drive belt 8 is tensioned, while at the same time the upper belt drum is relieved by moving the compensating roller 15 . The compensating roller 15 causes the displaceably mounted belt drive 2 to have approximately the same belt tension in any position between the extended rest position (FIG. 1) and the retracted working position (FIG. 2), despite the stationary, driven deflection roller 9 . Both drive belts 3 , 8 can additionally be tensioned by an eccentric tensioning device, not shown, in order to compensate for inaccuracies in length of the endless drive belts 3 , 8 .
The measuring drive roller 21 of the cable length measuring device 22 can additionally execute a limited path perpendicular to the direction of movement of the cable 18 and is pressed against the cable 18 by the force of springs and later driven by the moving cable 18 . If the cable 18 is missing, the measuring drive roller 21 does not touch the drive roller 12 and the cable length measuring device 22 is also not driven. For the exemplary embodiment described, the diameter of the drive roller 12 for the measuring drive roller 21 is selected to be slightly larger, such that the peripheral speed of the drive roller 12 is slightly greater than the peripheral speed of the drive belts 3 , 8 . This always creates a tension in the cable 18 between the exit from the belt drives 1 , 2 and the cable length measuring device 22 . This tension and the additional cable guide 32 prevent a cable jam before and after the cable length measuring device 22 .
A comparative slip measuring device is provided between the drive belt and the measuring drive roller of the cable length measuring device to monitor an abnormal cable tensile force or to prevent damage to the running drive belts when the cable is blocked. As soon as there is no rotational movement of the driven and moving drive belts Belt drive is stopped, the drive of the belt drives is interrupted.
The control of a blocked cable would also be possible by monitoring the torque of the drive motor of the belt drives by switching off the drive motor in the event of an abnormal increase in the motor torque due to the increase in friction between the belt drives and a blocked cable.

In obiger Beschreibung mit den zugehörigen Zeichnungen ist eine Einrichtung zum Zubringen eines Kabels in einen Kabel-Verarbeitungsautomaten beschrieben, bei welcher nach den Riementrieben eine unabhängige, separat angetriebene Antriebsrolle mit einer Messtreibrolle der Kabel-Längenmesseinrichtung zusammenarbeitet. Es ist ohne weiteres denkbar, anstelle der Messtreibrolle und der Kabel-Längenmesseinrichtung eine gewöhnliche einzelne Druckrolle 33 einzubauen und mit der angetriebenen Antriebsrolle zusammenarbeiten zu lassen. Die Kabel-Längenmesseinrichtung könnte in diesem Falle an einer anderen Stelle, beispielsweise auf der Kabel-Zuführseite angeordnet sein.
Es wäre auch möglich, die beschriebene Einrichtung ohne die verschiebbar gelagerte Klemm-Spannvorrichtung auf der Kabel-Zuführseite und/oder ohne die Klemmvorrichtung auf der Kabel-Austrittseite zu betreiben.
Ebenso ist in obiger Beschreibung ein doppelseitiger Zahnriemen vorgesehen, welcher gemeinsam die Zahnräder für die Riementriebe und das Zahnrad für die Antriebsrolle zur Messtreibrolle antreibt. Es wäre ohne weiters möglich mit dem doppelseitigen Zahnriemen nur die Zahnräder für die Riementriebe anzutreiben und die Antriebsrolle zur Messtreibrolle und/oder die Druckrolle mit einem separaten Antrieb, beispielsweise einem separaten Elektromotor auszurüsten.
In the above description with the associated drawings, a device for feeding a cable into a cable processing machine is described, in which, according to the belt drives, an independent, separately driven drive roller interacts with a measuring drive roller of the cable length measuring device. It is readily conceivable to install an ordinary single pressure roller 33 instead of the measuring drive roller and the cable length measuring device and to have it cooperate with the driven drive roller. In this case, the cable length measuring device could be arranged at another location, for example on the cable feed side.
It would also be possible to operate the described device without the displaceably mounted clamping tensioning device on the cable feed side and / or without the clamping device on the cable exit side.
Likewise, a double-sided toothed belt is provided in the above description, which drives the gearwheels for the belt drives and the gearwheel for the drive roller to the measuring drive roller. It would also be possible to drive the double-sided toothed belt only for the belt drives for the belt drives and to equip the drive roller for the measuring drive roller and / or the pressure roller with a separate drive, for example a separate electric motor.
