Ein solches Verfahren und eine solche Einrichtung ist aus der EP 0 881 720 bekannt, die eine Einrichtung zur Tüllenbestückung von elektrischen Kabeln beschreibt, bei der die Tüllen in einer Schiene angeliefert, jeweils einzeln von einem Pickdorn aufgepickt, von diesem durchstossen und in einer durchgehenden Bewegung auf einen Aufspreizer aufgeschoben werden. Anschliessend wird der Aufspreizer mit einer Drehvorrichtung verschwenkt und die auf diesem Aufspreizer befindliche Tülle mit Hilfe eines Tüllenaufnahmeteils auf einem entsprechend in dieser Achse gelagerten Kabel abgelegt.Such a method and such a device is from the EP 0 881 720 known that a device for the fitting of spouts describes electrical cables, in which the grommets in one Delivered rail, picked individually by a pick pin, pierced by it and in a continuous movement be pushed onto a spreader. Subsequently the spreader is pivoted with a rotating device and the spout on this spreader with the help of a Grommet receiving part on a correspondingly mounted in this axis Cable stored.

Ein weiteres Verfahren und Einrichtung zur Tüllenbestückung ist aus der EP 0 626 738 bekannt. Diese setzt eine Drehvorrichtung mit vier Dornen ein, die jeweils schrittweise um einen bestimmten Winkel weiterdrehbar sind, wobei das Aufschieben der Tülle auf den Dorn, das Aufweiten der Tülle auf einem weiteren Teil des Dornes sowie das Aufbringen der Tülle auf das Kabel in verschiedenen Drehpositionen der Drehvorrichtung durchgeführt wird. Diese Vorrichtung weist gegenüber anderen Tüllenbestückungsmaschinen, wie sie beispielsweise aus der EP 0 534 106 oder der EP 0 881 720 bekannt sind, den vorteil auf, dass durch den Einsatz eines Revolvers eine höhere Taktrate erreicht werden kann. Des weiteren ist diese Vorrichtung wartungsfreundlich, da die dem Verschleiss unterworfenen Komponenten leichter zugänglich sind. Another method and device for fitting spouts is known from EP 0 626 738. This sets a rotating device with four thorns, one step at a time Angle can be rotated further, pushing on the spout on the mandrel, expanding the spout on another part the mandrel as well as applying the grommet to the cable in various Rotational positions of the rotating device is carried out. Compared to other spout placement machines, this device as for example from EP 0 534 106 or EP 0 881 720 are known to have the advantage of being used of a revolver a higher clock rate can be achieved. Of furthermore, this device is easy to maintain because the Components subject to wear are more easily accessible.

Bei der Vorrichtung nach der EP 0 534 106 wird die Tülle aus der Förderschiene direkt in ein Tüllenaufnahmeteil gedrückt, welches anschliessend verschwenkt wird; um gegen ein Kabel vorgeschoben zu werden. Ein Aufweiten der Tülle findet nicht statt.In the device according to EP 0 534 106, the spout is made of Conveyor rail pressed directly into a sleeve receiving part, which is then pivoted; to be pushed against a cable to become. The spout does not widen.

Aus der EP 410 416 ist eine Tüllenbestückungseinheit bekannt, bei der eine Tülle mit Hilfe von Haltebacken in der Achse des Zentrierdorns, des Tüllenaufnahmeteils und des zu bestückenden Kabels gehalten wird. Anschliessend wird die Tülle durch den konischen Zentrierdorn aufgespreizt, durch ein Aufspreizteil gehalten und nach Einführen eines Kabels auf diesem abgesetzt. Diese Einrichtung weist eine langsame Taktrate auf, da alle Elemente entlang einer Achse angeordnet sind.A nozzle assembly unit is known from EP 410 416, in which a grommet with the help of holding jaws in the axis of the Centering mandrel, the sleeve receiving part and the one to be fitted Cable is held. Then the spout is replaced by the conical one Centering mandrel spread, held by a spreading part and placed on it after inserting a cable. This facility has a slow clock rate since all elements are arranged along an axis.

The mandrel 8 is advanced so far that the jaws 11 and 12 of the grommet receptacle 10 Can close spout 2.

Anschliessend wird durch eine weitere Relativbewegung zwischen den Schlittenelementen 23 und 24 die Tülle 2 auf ein vor den Backen 11 und 12 präsentiertes Kabel 13 aufgeschoben. Das Schlittenelement 24 ist mit dem Gestell der Vorrichtung fest verbunden. Alternativ kann jede als Relativbewegung bezeichnete Bewegung auch anders ausgestaltet sein, hier durch ein Vorschieben des Kabels 13 in die Tüllenaufnahme 10. Die kombinierte Schlittenbewegung gestattet einen einfachen Aufbau, der ohne weitere Adaptationen mit einer Vielzahl von Kabel präsentierenden Einrichtungen zusammenwirken kann.Then another relative movement between the slide elements 23 and 24, the spout 2 in front of the Jaws 11 and 12 presented cable 13 pushed on. The Carriage element 24 is fixed to the frame of the device connected. Alternatively, each can be referred to as a relative movement Movement can also be designed differently, here by pushing it forward of the cable 13 in the grommet receptacle 10. The combined Slide movement allows a simple structure that without further adaptations with a variety of cables presenting Facilities can work together.

Indem sich die Backen 11 und 12 in der dargestellten Art und Weise in senkrechter Richtung öffnen, kann das Kabel 13 mit dem bereits bestückten Tüllenelement 2 senkrecht aus der Zeichenebene der Fig. 2 auf den Betrachter entfernt werden, wobei ein weiteres Kabel 13 senkrecht von unterhalb der Zeichenebene einschwenkt, bevor der Schlitten 23 bezüglich der Basis 24 zurückfährt. Während dieses Zurückfahrens ist durch eine Relativbewegung des Schlittens 22 bezüglich dem Schlitten 23 die Drehvorrichtung 9 bereits wieder in die Ausgangsstellung mit senkrechtem Dorn 8 überführt worden und kann somit eine weitere Tülle 2 aufnehmen.By the jaws 11 and 12 in the manner shown and Open way in the vertical direction, the cable 13 with the already fitted grommet element 2 vertically from the drawing plane 2 are removed to the viewer, with another Cable 13 swings in vertically from below the drawing plane, before the carriage 23 moves back with respect to the base 24. During this retraction is due to a relative movement of the carriage 22 with respect to the carriage 23, the rotating device 9 already in the starting position with vertical Mandrel 8 has been transferred and can therefore be a further spout 2 take up.

Bei der in der Fig. 2 dargestellten Orientierung der Dreheinrichtung wird beispielsweise mit Hilfe einer Lichtschranke festgestellt, ob auf dem Rohr 8 ein Tülle aufsitzt und falls nicht gegebenenfalls ein Fehlersignal ausgegeben. Vorteilhafterweise ist im Bereich der Backen 11 und 12 unterhalb von diesen, beispielsweise am Schlitten 22 oder 23 montiert, ein Luftauslass vorgesehen, durch den beim Öffnen der Backen 11 und 12 ein Luftstoss auf den Bereich der eingelegten Tülle 2 ausgelöst wird, so dass diese, falls kein Kabel präsentiert worden ist, auf das die Tülle 2 -aufgeschoben werden konnte, die Tülle 2 weggeblasen wird, um für den nächsten Bestückungsvorgang die Backen 11 und 12 zu leeren.In the orientation of the rotating device shown in FIG. 2 is detected, for example, with the help of a light barrier, whether there is a spout on the pipe 8 and if not an error signal may be output. advantageously, is in the area of the jaws 11 and 12 below these, for example mounted on slide 22 or 23, an air outlet provided by an air blast when opening the jaws 11 and 12 is triggered on the area of the inserted spout 2, so that, if no cable has been presented, that the Spout 2 - could be pushed on, the spout 2 blown away is in order for the next assembly process the jaws 11 and 12 to empty.

Durch die Aufnahme der Tülle 2 auf den konisch sich aufweitenden Dorn 5 und dessen Vorschieben gegen eine Blende 6, kann die Tülle in wenigen Prozessschritten mit einer ersten Bearbeitungseinheit und in einem ersten Schritt zur Aufnahme eines Kabels 13 vorbereitet werden. Die zweite Bearbeitungseinheit umfasst die Drehvorrichtung 9 mit dem Rohr 8, auf welches die Tülle 2 übergeben wird. Diese wird in einer durch eine L-förmige Zwangsführung kombinierten Dreh- und Vorwärtsbewegung in einem zweiten Schritt verschwenkt, um die Tülle 2 in einer Tüllenaufnahme 10 einzuführen.By including the spout 2 on the conically widening Mandrel 5 and its advancement against an aperture 6, the spout in a few process steps with a first processing unit and in a first step for receiving a cable 13 to get prepared. The second processing unit comprises the Rotary device 9 with the tube 8, on which the spout 2 pass becomes. This is done in an L-shaped positive guide combined rotation and forward movement in a second Step pivoted around the spout 2 in a spout receptacle 10 introduce.

In einem dritten Schritt schliesslich wird die vorgenannte Einheit aus Drehvorrichtung 9 und Tüllenhalterung 10 gegen ein Kabel 13 vorgeschoben und anschliessend durch eine Relativbewegung der Elemente 9 und 10 gegeneinander die Tülle 2 auf dem Kabel 13 abgesetzt. Durch eine zur Förderrichtung der Kabel 13 senkrechten Anordnung der Backen 11 und 12 kann das Kabel 13 bereits entnommen werden, bevor die Tüllenhalterung 10 zurückfährt. Während des Absetzens der Tülle 2 auf dem Kabel 13 kann bereits die nächste Tülle 2 durch den Dorn 5 aufgenommen und durch die Blende 6 vorgespreizt werden. Die Verbindung zwischen diesen beiden Bewegungen wird durch die kombinierte Dreh- und Translationsbewegung der Vorrichtung 9 gebildet. Damit sind sehr geringe Taktzeiten bei der Tüllenbestückung erreichbar.Finally, in a third step, the aforementioned unit from rotating device 9 and grommet holder 10 against a cable 13 advanced and then by a relative movement the elements 9 and 10 against each other the grommet 2 on the cable 13 discontinued. By a perpendicular to the conveying direction of the cable 13 Arrangement of the jaws 11 and 12, the cable 13 can already be removed before the grommet holder 10 moves back. While the placement of the grommet 2 on the cable 13 can already next grommet 2 received through the mandrel 5 and through the panel 6 can be spread. The connection between these two Movements become through the combined rotation and translation movement the device 9 is formed. This means very short cycle times accessible when fitting the grommet.

Durch die Trennung der Elemente ist die Modularität der Vorrichtung hervorragend. Bei einer Umrüstung der Einrichtung auf eine andere Tüllengrösse sind somit auszuwechseln: die Förderschiene 1, der Dorn 5, der vorteilhafterweise mit einem Steckverschluss eingesetzt ist, das Rohr 8, welches ebenfalls in der Drehvorrichtung 9 eingesteckt ist, sowie die Backen 11 und 12 der Tüllenaufnahme 10. Somit kann eine Vorrichtung mit leicht erreichbaren Verschleissteilen angegeben werden, die wirtschaftlich vorteilhaft ist und mit wenigen Handgriffen umgerüstet werden kann.The modularity of the device is due to the separation of the elements outstanding. When converting the facility to a other grommet sizes must therefore be replaced: the conveyor rail 1, the mandrel 5, which advantageously with a plug closure is used, the tube 8, which is also in the rotating device 9 is inserted, and the jaws 11 and 12 of the grommet holder 10. Thus, a device with easily accessible Wear parts are specified that are economical is advantageous and can be converted in just a few steps can.

Die Fig. 3 zeigt in schematischer Weise eine Möglichkeit der Ausgestaltung der Zwangsführung, wobei der Rahmen zu dem Schlittenelement 23 gehört und die Zwangsführung 31 ein L bildet, in dem beispielsweise ein mit der Drehvorrichtung 9 verbundenes Kugellager abrollt. Anstelle einer Verschwenkung um die in der Fig. 3 dargestellten 90 Grad sind auch andere Winkeleinstellungen möglich. In der Fig. 2 ist zu erkennen, dass das Rohr 8, fluchtend mit dem Dorn 5' einen kleinen Winkel von ungefähr 1 bis 2 Grad aufweist. Zwischen der Aufnahme einer Tülle 2 mit dem Dorn in der Position 5 und der Weiterverarbeitung der aufgenommenen Tülle 2 in der Position 5' besteht ebenfalls ein Winkel von 10 bis 15 Grad, welcher ein Ausfluss des Platzbedürfnisses für das Ende der Schiene 1 und den Dornhalter und -antrieb ist.3 shows a possibility of the in a schematic manner Design of the positive guidance, the frame to the slide element 23 belongs and the forced guidance 31 forms an L, in which, for example, a ball bearing connected to the rotating device 9 rolls. Instead of a pivoting around the in the 3 90 degrees are other angle settings possible. 2 that the tube 8, aligned with the mandrel 5 'a small angle of approximately 1 has up to 2 degrees. Between the inclusion of a spout 2 with the Mandrel in position 5 and the processing of the recorded Spout 2 in position 5 'also has an angle from 10 to 15 degrees, which is an outflow of space for the end of the rail 1 and the mandrel holder and drive.
