Description

Technisches GebietTechnical area

In vielen Einsatzgebieten, insbesondere bei der Fertigung von Kabelsätzen für Kraftfahrzeuge, ist es wünschenswert, Kabelwickel vorbestimmter Länge zur Verfügung zu haben. Die vorbereiteten Kabelwickel sind einfach zu handhaben und zu montieren.In many applications, especially in the manufacture of cable harnesses for motor vehicles, it is desirable to have cable reels of predetermined length available. The prepared cable wraps are easy to handle and assemble.

Das Dokument US-A-5 063 974 offenbart ein Verfahren und eine Vorrichtung zur maschinellen Herstellung von spulenlosen Kabelwickeln gemäß dem Oberbegriff des Anspruchs 1, bzw. 7.The document US-A-5 063 974 discloses a method and an apparatus for the manufacture of coilless cable coils according to the preamble of claim 1 or 7, respectively.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine zur Durchführung des Verfahrens geeignete Vorrichtung für die maschinelle Herstellung von spulenlosen Kabelwickeln zu schaffen. Das Verfahren bzw. die Vorrichtung soll möglichst einfach sein und eine hohe Fertigungsgeschwindigkeit zulassen.The invention has for its object to provide a method and an apparatus suitable for carrying out the method for the machining of coilless cable coils. The method and the device should be as simple as possible and allow a high production rate.

Die Lösung der gestellten Aufgabe erfolgt bei dem Verfahren zur maschinellen Herstellung von spulenlosen Kabelwickeln gemäß dem Anspruch 1.The solution of the object is achieved in the method for the machine production of bobbinless cable winding according to claim 1.

Die zur Durchführung des Verfahrens geeignete Vorrichtung zeichnet sich durch die Merkmale des unabhängigen Anspruchs 7.The device suitable for carrying out the method is characterized by the features of independent claim 7.

Bei der Durchführung des Verfahrens wird der Kabelstrang über eine Kabelzuführung einer Haltevorrichtung bzw. Führungsvorrichtung, zugeführt, welche das freie vordere Kabelende einem mit einer Wickeleinrichtung verbundenen Greifer übergibt. Danach wird von der Wickeleinrichtung ein Kabelstrang vorbestimmter Länge aufgewickelt, wobei das vordere Kabelende vom Greifer gehalten bleibt. Der gebildete Wickel wird von der Wickeleinrichtung einer Fixiereinrichtung übergeben, welche den Wickel übernimmt. Die Fixiereinrichtung legt sodann den Wickel auf einer unterhalb der Wickeleinrichtung liegenden Tischablage ab, auf dem der Wickel an mindestens einer Stelle durch einen Kabelbinder umschlossen wird. Der Kabelbinder hält die einzelnen Wickelstränge zusammen. Sodann wird das vordere Kabelende durch den Greifer einer längs der Tischablage in der Tischebene verfahrbaren ersten Kluppe zugeführt und darin festgeklemmt. Danach wird der Greifer in entsprechender Weise gedreht und aus seiner unteren, am Tisch angrenzenden Lage wieder nach oben geführt, nimmt sodann den im Bereich oberhalb der ersten Kluppe liegenden Kabelstrang und hält ihn fest. Gleichzeitig wird eine Trenneinrichtung herangeführt, welche den Kabelstrang durchtrennt. Das nach der Durchtrennung des Kabelstrangs entstandene hintere Ende des Kabelstrangs wird durch den Greifer durch Absenken einer zweiten Kluppe zugeführt, welche der ersten Kluppe vorauseilt. Das Ende des Kabelstrangs wird in der zweiten Kluppe festgeklemmt. Mit der Bewegung der Kluppen wird der Wickel auf der Tischablage entlang einer Verpackung bzw. die überstehenden Kabelenden verschiedenen Bearbeitungsstationen zugeführt.When carrying out the method, the cable strand is fed via a cable feed to a holding device or guide device, which transfers the free front cable end to a gripper connected to a winding device. Thereafter, a cable strand of predetermined length is wound up by the winding device, wherein the front end of the cable is held by the gripper. The formed winding is transferred from the winding device of a fixing device which takes over the winding. The fixing device then deposits the winding on a table rest lying below the winding device, on which the winding is enclosed at least at one point by a cable tie. The cable tie holds the individual winding strands together. Then, the front end of the cable is fed by the gripper of a movable along the table shelf in the table level first clip and clamped therein. Thereafter, the gripper is rotated in a similar manner and out of its lower, adjacent to the table position back up, then takes the lying in the area above the first cable harness and holds him firmly. At the same time a separation device is introduced, which cuts through the cable harness. The rear end of the wire harness resulting from the severing of the wire harness is fed by the gripper by lowering a second wire leading the first wire. The end of the harness is clamped in the second clip. With the movement of the clips, the winding is fed to the table tray along a package or the protruding cable ends to various processing stations.

Um eine möglichst einwandfreie Übergabe des vorderen Kabelendes aus der Haltevorrichtung in den Greifer durchzuführen, ist es günstig, wenn in der Haltevorrichtung das vordere Kabelende gespannt wird. Hierfür ist die Haltevorrichtung zweiteilig ausgeführt, so dass der Greifer zwischen die beiden Teile der Haltevorrichtung eingreifen kann.In order to carry out a possible flawless transfer of the front cable end of the holding device in the gripper, it is advantageous if the front end of the cable is tensioned in the holding device. For this purpose, the holding device is made in two parts, so that the gripper can engage between the two parts of the holding device.

Für das Erfassen des vorderen Kabelendes ist der an der Wickeleinrichtung angebrachte Greifer an die als Übergabestelle funktionierende Haltevorrichtung heranfahrbar. Auch zur Übergabe der Kabelenden an die Kluppen wird der Greifer unabhängig zu der Wickeleinrichtung an die Kluppen herangefahren. Sowohl beim Übergabevorgang in der Haltevorrichtung als auch bei der Übergabe an den Kluppen wird der Greifer abgesenkt bzw. hochgezogen.For detecting the front end of the cable attached to the winder gripper can be moved to the functioning as a transfer point holding device. Also for the transfer of the cable ends to the clips, the gripper is moved independently of the winding device to the clips. Both during the transfer process in the holding device as well as the transfer to the clips, the gripper is lowered or pulled up.

Die Vorrichtung zur Durchführung des Verfahrens ergibt eine automatische Herstellung der spulenlosen Kabelwickel. In einer Aufnahme der Vorrichtung wird eine Vorratskabelrolle eingesetzt. Eine Kabelzuführung mit Transportrollen erfasst den Kabelstrang und führt denselben der Haltevorrichtung zu, in der der Kabelstrang gehalten wird. Die Haltevorrichtung hat einen ausfahrbaren Abstützarm. Sowohl in der Haltevorrichtung als auch im Stützarm sind unter Federspannung stehende Klemmleisten vorhanden, die voneinander beabstandet das ihr zugeführte vordere Ende erfassen. Daher wird das vordere Kabelende gespannt. Während dieses Vorgangs befindet sich die Wickeleinrichtung in einer Lage oberhalb der Kluppen. Die Wickeleinrichtung selbst besteht aus einer Wickelwelle, an der mindestens drei aufspreizbare Wickelarme befestigt sind. Außerdem ist sie mit einem Greifer ausgestattet. Dieser Greifer ist mit zwei voneinander beabstandeten gabelartigen und unter Federspannung stehenden Klemmzangen versehen. Er ist darüber hinaus nach unten über die Wickelarme verschiebbar an der Wickelwelle angebracht. Um das vordere Ende des Kabelstrangs zu erfassen, wird die Wickeleinrichtung mit dem Greifer an die Haltevorrichtung herangeführt. Dabei sind die Wickelarme eingeschwenkt und der Greifer steht mit seinen Klemmzangen radial über die Wickelarmenden hinaus hervor. Durch Absenken des Greifers gelangen dessen Klemmzangen zwischen die Haltevorrichtung und dessen Stützarm und können das vordere Kabelende sicher erfassen. Danach wird die Wickeleinrichtung in eine Lage oberhalb der Tischablage gefahren, wobei der Greifer den Kabelstrang mitzieht bzw. die Kabelzuführung exakt soviel Leitung synchron nachspult, wie die Wickeleinrichtung wegfährt und aufwickelt. Gleichzeitig werden die Wickelarme aufgespreizt, die an ihren Enden mit halbrunden, nach außen gerichteten Wickelhaken versehen sind. Dabei wird der Wickelkern, gebildet durch die Wickelarme, unterschiedlich weit aufgefaltet, damit ein einheitlicher Kabelüberstand der Kabelenden vom Wickel nach dem Wickeln und Binden des Wickels erreicht wird. Der Wickelvorgang wird solange durchgeführt, bis die vorbestimmte Länge des Kabelstrangs aufgewickelt ist. Danach wird die Fixiereinrichtung unterhalb der Wickeleinrichtung angehoben. Diese übernimmt den Wickel und wird wieder auf die Tischablage abgesenkt. An mindestens einer Stelle wird sodann der Wickel von einem Kabelbinder oder Fixierelement umschlossen. Der Greifer führt sodann das vordere Kabelende einer kastenartigen Kluppe zu und übergibt das vordere Kabelende der Kluppe. Die Kluppe hat eine kastenartige Kontur, so dass die Klemmzangen des Greifers über diese Kontur greifen können und dadurch das Kabelende in die Kluppe eindrücken können. Danach wird der Greifer durch entsprechende Bewegungen der Wickeleinrichtung an die Haltevorrichtung für den Kabelstrang herangeführt, in dem die Wickeleinrichtung gedreht und hochgezogen wird. Der Greifer erfasst sodann den Kabelstrang, der über eine Trenneinrichtung durchtrennt wird. Das so entstandene hintere Kabelende wird sodann vom Greifer der zweiten Kluppe zugeführt die in Bewegungsrichtung vor der ersten Kluppe liegt. In der zweiten Kluppe wird das Kabelende festgehalten, womit nach Freigabe des Wickels durch die Fixiereinrichtung der Wickelvorgang beendet ist.The apparatus for carrying out the method results in an automatic production of the bobbinless cable wraps. In a recording of the device, a supply cable roll is used. A cable feed with transport rollers detects the cable harness and leads the same to the holding device, in which the cable harness is held. The holding device has an extendable support arm. Both in the holding device and in the support arm spring-loaded terminal strips are present, the distance from one another detect the supplied front end. Therefore, the front cable end is tensioned. During this process, the winding device is in a position above the clips. The winding device itself consists of a winding shaft to which at least three expandable winding arms are attached. In addition, it is equipped with a gripper. This gripper is provided with two spaced fork-like and spring-loaded clamps. It is also mounted downwards over the winding arms on the winding shaft. To grasp the front end of the cable harness, the winding device is brought to the holding device with the gripper. Here are the wrapping arms swung in and the gripper stands with its clamping forceps radially beyond the Wickelarmenden also out. By lowering the gripper reach the clamping pliers between the holding device and the support arm and can detect the front cable end safely. Thereafter, the winding device is moved to a position above the table shelf, wherein the gripper pulls along the cable harness or rewinding the cable feed exactly as much line synchronously, as the winding device wegfährt and wound up. At the same time, the winding arms are spread open, which are provided at their ends with semicircular, outwardly directed winding hooks. In this case, the winding core, formed by the winding arms, unfolded to different degrees, so that a uniform cable projection of the cable ends is achieved by the winding after winding and binding of the coil. The winding process is carried out until the predetermined length of the wire harness is wound up. Thereafter, the fixing device is raised below the winding device. This takes over the winding and is lowered back onto the table shelf. At least one point then the winding is enclosed by a cable tie or fixing. The gripper then feeds the front cable end to a box-like clip and passes the front cable end of the clip. The clip has a box-like contour, so that the grippers of the gripper can grasp this contour and thereby push the cable end into the clip. Thereafter, the gripper is brought by appropriate movements of the winding device to the holding device for the wire harness, in which the winding device is rotated and pulled up. The gripper then detects the harness, which is severed by a separator. The resulting rear end of the cable is then fed by the gripper of the second clip which lies in the direction of movement in front of the first clip. In the second clip, the cable end is held, whereby after release of the coil by the fixing device of the winding process is completed.

Die Klemmleisten und Klemmzangen von Greifer bzw. Kluppen sind mit Antrieben ausgestattet, über die die Klemmleisten und Klemmzangen geöffnet werden.The clamping bars and clamps of grippers or clips are equipped with drives that open the clamping strips and clamps.

Die Wickelwelle mit ihrer Wickeleinrichtung ist mit Servoantrieben versehen, welche eine voneinander unabhängige Betätigung der Wickelwelle, längs oder quer zu ihrer Achse, ihre Drehbewegung und die Spreizbewegung der Wickelarme erlauben.The winding shaft with its winding device is provided with servo drives, which allow independent operation of the winding shaft, along or transverse to its axis, its rotational movement and the spreading movement of the winding arms.

Die Servo- und Pneumatikantriebe werden in einem aufeinander abgestimmten Arbeitstaktprogramm gesteuert.The servo and pneumatic drives are controlled in a coordinated work cycle program.

Um einen einheitlichen Überstand der Kabelenden über den Kabelwickel zu erreichen, ist es von Vorteil, wenn die Wickelarme in Abhängigkeit von der gewollten Kabellänge aufgespreizt werden. Hierdurch können auftretende Längenunterschiede am Kabel ausgeglichen werden.In order to achieve a uniform projection of the cable ends over the cable winding, it is advantageous if the winding arms are spread apart depending on the desired cable length. As a result, occurring length differences on the cable can be compensated.

Außerdem ist es günstig, wenn die Wickelarme leicht nachgiebig ausgebildet werden. Dies kann dadurch geschehen, dass die Wickelarme aus einem elastischen Material, beispielsweise aus Kunststoff, hergestellt werden, oder auch dadurch, dass die Wickelarme nachgiebig angelenkt sind, zum Beispiel über entsprechende Federpakete.Moreover, it is advantageous if the winding arms are designed to be slightly yielding. This can be done by the winding arms are made of an elastic material, such as plastic, or also in that the winding arms are articulated resilient, for example via corresponding spring assemblies.

Die in der Fig. 1 gezeigte Vorrichtung besteht im Wesentlichen aus einer Aufnahme für eine Kabelrolle 1, der Kabelzuführung 8, der Haltevorrichtung 9, der Trenneinrichtung 20, der Wickeleinrichtung 2 mit dem Greifer 11, einer Fixiereinrichtung 12 mit Kabelbinder 4, einer Tischablage 13 sowie längs der Tischablage 13 verfahrbaren Kluppen 16 und 19.The device shown in FIG. 1 essentially consists of a receptacle for a cable reel 1, the cable feed 8, the holding device 9, the separating device 20, the winding device 2 with the gripper 11, a fixing device 12 with cable tie 4, a table shelf 13 and along the table shelf 13 movable clips 16 and 19.

Auf der Kabelrolle 1 befindet sich ein Vorrat des Kabelstrangs 7, der zu einzelnen Kabelsträngen 7 vorbestimmter Länge zu einem Wickel 3 maschinell gewickelt wird. Der Kabelstrang 7 wird von der Kabelzuführung 8 in die Haltevorrichtung 9 überführt, welche ihrerseits das freie vordere Kabelende 10 den mit der Wickeleinrichtung 2 verbundenen Greifer 11 übergibt. Die Wickeleinrichtung 2 ist an einem nicht näher gezeigten Arm mit Antriebseinrichtungen gehalten und ist quer zur Tischablage 13 verschiebbar.On the cable reel 1 is a supply of the cable harness 7, which is wound into individual cable strands 7 of predetermined length to a winding 3 by machine. The cable harness 7 is transferred from the cable feed 8 in the holding device 9, which in turn passes the free front cable end 10 connected to the winding device 2 gripper 11. The winding device 2 is held on a not shown arm with drive means and is transversely displaceable to the table shelf 13.

In der Fig. 2 ist in der Schrägansicht die Lage der einzelnen Teile zueinander vor der Übergabe gezeigt. Die Wickeleinrichtung 2 mit dem Greifer 11 befindet sich oberhalb der Übergabestelle und das vordere Kabelende 10 steht frei über die Haltevorrichtung 9 hinaus hervor. Auf der Tischablage 13 liegen zwei bereits fertige Wickel 3 auf, wobei das vordere Ende 10 und das hintere Ende 18 des jeweiligen Kabelstrangs 7 in den Kluppen 16 bzw. 19 gehalten ist. Die an der Wickeleinrichtung 2 vorhandenen Wickelarme 21 sind eingeklappt.In Fig. 2, the position of the individual parts to each other before handing over is shown in the oblique view. The winding device 2 with the gripper 11 is located above the transfer point and the front cable end 10 protrudes freely beyond the holding device 9 addition. On the table tray 13 are two already finished winding 3, wherein the front end 10 and the rear end 18 of the respective wire harness 7 is held in the clips 16 and 19 respectively. The existing on the winding device 2 winding arms 21 are collapsed.

Die Fig. 3 zeigt das Erfassen des Kabelendes 10 durch den Greifer 11. Hierfür ist ein Stützarm 31 aus der Haltevorrichtung 9 ausgefahren, um das Kabelende 10 mit einer am Stützarm 31 befestigten Klemmgabel 22 zu erfassen. In der Haltevorrichtung 9 befindet sich eine zweite Klemmgabel 23, welche ebenfalls das Kabelende 10 ergreift. Durch die beiden Klemmgabeln 22 und 23 wird das Kabelende 10 fest eingespannt und der Greifer 11 kann mit seinen voneinander beabstandeten gabelartigen Klemmzangen 24 das Kabelende 10 übernehmen.3 shows the detection of the cable end 10 by the gripper 11. For this purpose, a support arm 31 is extended from the holding device 9 in order to detect the cable end 10 with a clamping fork 22 fastened to the support arm 31. In the holding device 9 is a second clamping fork 23, which also engages the cable end 10. Through the two terminal forks 22 and 23, the cable end 10 is firmly clamped and the gripper 11 can take over the cable end 10 with its spaced apart fork-like clamping forceps 24.

Nachdem der Greifer 11 das Kabelende 10 fest erfasst hat, wird die Wickeleinrichtung 2 mit dem Greifer 11 in Richtung auf die Fixiereinrichtung 12 bewegt und oberhalb der Tischablage 13 angehalten. Fig. 4. Der Greifer 11 selbst durchfährt dabei zunächst die Klemmgabel 22, welche für diesen Zweck ausschwenkbare Klemmleisten hat. Die aus Kunststoff bestehenden Wickelarme 21 der Wickeleinrichtung 2 werden ausgefahren und der Wickelvorgang beginnt, während das vordere Kabelende 10 noch vom Greifer 11 gehalten wird.After the gripper 11 has firmly gripped the cable end 10, the winding device 2 is moved with the gripper 11 in the direction of the fixing device 12 and stopped above the table support 13. Fig. 4. The gripper 11 itself passes through first the clamping fork 22, which has swung out for this purpose terminal strips. The existing winding plastic arms 21 of the winding device 2 are extended and the winding process begins, while the front end of the cable 10 is still held by the gripper 11.

Nach dem Aufwickeln eines Kabelstrangs 7 vorbestimmter Länge ist der Wickelvorgang beendet. Danach ergreift die Fixiereinrichtung 12 durch Einschwenken ihrer Arme 34 den Wickel 3, wie in der Fig. 5 gezeigt.After winding a wire harness 7 predetermined length of the winding process is completed.
