Description

Die Erfindung betrifft ein Verfahren zum spaltfreien Aufwikkeln von Kabeln auf eine drehbar angetriebene Kabeltrommel, wobei ein ankommendes Kabel an der Auflaufstelle in einer neuen Windung unmittelbar neben die vorhergehende Windung gewickelt wird, und wobei der Auflaufwinkel des Kabels nachgeführt wird, wenn eine Überwachungseinrichtung einen Spalt zwischen den letzten Windungen feststellt.The invention relates to a method for gap-free winding from cables to a rotatably driven cable drum, where an incoming cable at the run-up point in a new turn immediately next to the previous turn and where the run-up angle of the cable is tracked when a monitoring device has a gap between the last turns.

Bei der geregelten Kabelverlegung wird das Kabel auf die Kabeltrommel aufwickelt, während die Trommel quasi kontinuierlich in Achsrichtung verschoben wird. Die Verschiebung beträgt pro Trommelumdrehung ungefähr einen Kabeldurchmesser. Dieser Verlegung wird die Verlegekorrektur im Bedarfsfall überlagert. Die Verlegekorrektur wird mit einer angetriebenen Kabelführungseinrichtung, die beispielsweise eine Verlegehand oder eine Führungsrolle aufweisen kann, durchgeführt.With the regulated cable laying, the cable is on the cable drum winds up while the drum is quasi continuous is moved in the axial direction. The shift is approximately one cable diameter per drum revolution. This relocation becomes the relocation correction if necessary superimposed. The laying correction is driven by a Cable routing device, for example a laying hand or can have a guide role.

Aus der EP-B10043366 ist ein Verfahren zum Aufwickeln von Kabel auf eine Kabeltrommel bekannt, bei dem das fortlaufend so zugeführt wird, dass eine möglichst gleichmäßige Bewicklung erreicht wird. Eine Fernsehkamera ist für die Überwachung der Lage des Kabels vorgesehen, und die von der Fernsehkamera ermittelten Daten über die jeweilige Lage der Windung wird einem Rechner zugeführt, der die entsprechende Verlegekorrektur veranlaßt. Dabei erfaßt eine als erste Meßeinrichtung zur Überwachung eingesetzte, etwa tangential auf die Wickellage gerichtete Videokamera die gegebenenfalls von einem Scheinwerfer beleuchtete Wickellage. Durch die Videokamera wird dabei die Lage der Windungsflanke der zuletzt gewickelten Windung bestimmt und zwar an einer um einen bestimmten Spulendrehwinkel von der Auflaufstelle des Kabels entfernt liegenden Punkt. Des weiteren ist eine Meßeinrichtung zur Erfassung der jeweiligen Changierposition der Kabeltrommel und ein Fühler für das Kabel vorgesehen. Aus den Meßdaten beider Meßeinrichtungen werden die Relativpositionen berechnet, die die Kabeltrommel und die Führungseinrichtung für das Kabel nach dem Drehen der Kabeltrommel zur Aufrechterhaltung des Auflaufwinkels erreicht haben müssen. Eine Steuereinrichtung dient dazu, einen konstanten Auflaufwinke1 zu Verlegung der Windung innerhalb jeder Wickellage aufrecht zu erhalten.EP-B10043366 describes a method for winding up cables known on a cable drum, in which the continuously so that the winding is as uniform as possible is achieved. A television camera is for surveillance Position of the cable provided, and those determined by the television camera One gets data about the respective position of the turn Computer supplied, the corresponding laying correction causes. It detects a first measuring device for Monitoring used, approximately tangential to the winding position directional video camera which may be from a headlight illuminated wrapping. Through the video camera the position of the turn flank of the last turn wound determined and that at a specific coil rotation angle away from the run-up point of the cable Point. There is also a measuring device for detection the respective traversing position of the cable drum and a sensor provided for the cable. From the measurement data of both measuring devices the relative positions are calculated that the Cable drum and the guide device for the cable after rotating the cable drum to maintain the run-up angle must have reached. A control device is used to lay a constant run-up angle1 Maintain winding within each winding layer.

Um demgegenüber eine einfachere und möglichst schnelle und effiziente Verlegekorrektur durchführen zu können, ist aus der DE 19726285.6 A1 bekannt, bezogen auf die Kabeltrommel-Achse in radialer Richtung gesehen jeweils für mindestens zwei Windungen der neuen Wickellage die Lage der Scheitelpunkte dieser Windungen zu bestimmen und bei einer Abweichung dieser Scheitelpunkte von einem Sollwert eine die Abweichung verringernde Verlegekorrektur durchzuführen. Dabei wird in paralleler Richtung zur Kabeltrommel-Achse gesehen im Bereich des Auftreffpunktes des Kabels jeweils für mindestens zwei Windungen der neuen Wickellage der Abstand der Scheitelpunkte dieser Windungen bestimmt. Wenn sich der Spalt zwischen der vorletzten und der letzten Windung vergrößert und sich dadurch der Abstand zwischen den benachbarten Scheitelpunkten vergrößert, wird eine Verlegekorrektur in dem Sinne durchgeführt, dass der seitliche Abstand der letzten Windung gegenüber der vorletzten Windung verkleinert wird.In contrast, a simpler and as fast as possible and It is no longer possible to carry out efficient laying corrections known from DE 19726285.6 A1, based on the cable drum axis seen in the radial direction for at least two turns of the new winding position the position of the vertices to determine these turns and in the event of a deviation this apex from a set point is the deviation to carry out reducing laying correction. Thereby in seen parallel to the cable drum axis in the area the point of impact of the cable for at least two Turns of the new winding layer the distance of the vertices of these turns determined. If the gap between the penultimate and the last turn enlarged and thereby the distance between the adjacent vertices enlarged, a laying correction is carried out in the sense that the lateral distance opposite the last turn the penultimate turn is reduced.

Die bekannten Verfahren zur Verlegekorrektur sind solange brauchbar, wie die Kabel in geordneter Weise auf die Kabeltrommel aufgewickelt werden. Bei höheren Geschwindigkeiten besteht jedoch die Gefahr, dass das Kabel beim Aufwickeln verspringt oder dass sich die Kabel beim Aufwickeln kreuzen. Dadurch entsteht das Problem, dass die Einrichtungen, die die automatische Verlegekorrektur durchführen sollen, keine Informationen mehr darüber haben, welches die letzte und die vorletzte Windung beim Aufwickeln des Kabels war. Dann läßt sich die automatische Verlegekorrektur nicht mehr in der vorgesehenen Art durchführen.The known methods for laying correction are long usable as the cables in an orderly manner on the cable drum be wound up. At higher speeds however, there is a risk that the cable will wind up jumps or that the cables cross during winding. This creates the problem that the facilities that the should perform automatic laying correction, no information have more about which one is the last and the other penultimate turn when winding the cable was. Then lets the automatic laying correction is no longer in the intended Perform kind.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum spaltfreien Aufwickeln von Kabel auf einer Kabeltrommel bei vollautomatischer Verlegekorrektur bereitzustellen, die die Möglichkeit bieten soll, die letzte und die vorletzte Windung voneinander zu unterscheiden und damit Wickelfehler festzustellen, die bisher nicht gehandhabt werden konnten.In contrast, the invention is based on the object Method and device for gap-free winding of Cable on a cable drum with fully automatic laying correction to provide, which should provide the opportunity distinguish the last and the penultimate turn from each other and thus to determine winding errors, which so far could not be handled.

Zur Lösung dieser Aufgabe ist das eingangs genannte Verfahren dadurch gekennzeichnet, dass eine sich zeitlich verändernde Markierung auf das Kabel vor dem Aufwickeln desselben aufgebracht wird, und dass der Zustand der Markierung wenigstens in der neuen und der vorhergehenden Windung detektiert wird, wobei die neue Windung von der vorhergehenden Windung zu unterscheiden ist. Bei dem erfindungsgemäßen Verfahren wird somit eine sich zeitlich verändernde Markierung beim Aufwickeln des Kabels aufgebracht, deren Zustand detektiert wird, um die aktuell entstehende Windung von der unmittelbar vorher aufgewickelten
Windung eindeutig unterscheiden zu können. Das Kabel kann daher auch in den Fällen mit automatischer Verlegekorrektur aufgewickelt werden, die, wie oben dargelegt, bisher nicht gehandhabt werden konnten. Durch das erfindungsgemäße Verfahren werden lagenweise aufgebaute Wickelpakete erzielt, wobei die Kabelwindungen dicht nebeneinander liegen. Eine Verlegekorrektur von Hand ist nicht mehr erforderlich. Vielmehr führt die Kabelführungseinrichtung das auflaufende Kabel in die Sollposition neben der letzten Windung, und während sich das Kabel von der Sollposition entfernt, werden die erforderlichen Verlegekorrekturen automatisch vorgenommen.To achieve this object, the method mentioned at the outset is characterized in that a time-changing marking is applied to the cable before winding it up, and in that the state of the marking is detected at least in the new and the previous turn, the new turn of the previous turn is to be distinguished. In the method according to the invention, a time-changing marking is thus applied when the cable is being wound up, the state of which is detected by the winding which is currently being formed from the winding which was wound up immediately before
To be able to clearly distinguish between the turns. The cable can therefore also be wound up with automatic laying correction in cases which, as explained above, could not previously be handled. Layer-by-layer winding packages are achieved by the method according to the invention, the cable windings lying close together. Manual adjustment is no longer necessary. Rather, the cable routing device guides the incoming cable into the target position next to the last turn, and while the cable is moving away from the target position, the necessary laying corrections are made automatically.

Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass die Markierung dadurch erzeugt wird, dass die Oberfläche des Kabels erwärmt wird, und dass die Wärmeabstrahlung des Kabels in der neuen und der vorhergehenden Windung detektiert wird. Die Kabeloberfläche wird somit kurz vor dem Aufwickeln des Kabels auf die Kabeltrommel erwärmt, und die Temperatur des auflaufenden Kabels wird mit der Temperatur der benachbarten Kabelwindung verglichen, wobei die zweithöchste Temperatur bei der vorher aufgewickelten Windung festgestellt wird. Die vorher aufgewickelten Windungen haben einer quasi kontinuierlichen oder exponentiellen Abkühlfunktion entsprechend niedrigere Oberflachentemperaturen. Somit können die Windungen des Kabels nach ihrer Reihenfolge der Bewicklung unterschieden werden.An advantageous embodiment of the method according to the invention is characterized in that the marking is generated that the surface of the cable is heated and that the heat radiation of the cable in the new and the previous turn is detected. The cable surface is thus shortly before the cable is wound onto the cable drum warmed up, and the temperature of the cable coming out is compared with the temperature of the neighboring cable turn, being the second highest temperature at the previously wound Winding is determined. The previously wound up Turns have a quasi-continuous or exponential Cooling function correspondingly lower surface temperatures. Thus, the turns of the cable can their order of wrapping can be distinguished.

Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass die Markierung dadurch erzeugt wird, dass die Oberfläche des Kabels abgekühlt wird, und dass die Wärmeabstrahlung des Kabels in der neuen und der vorhergehenden Windung detektiert wird. Eine Kaltmarkierung ist insbesondere dann vorteilhaft, wenn die Kabeloberfläche beim Aufwickeln deutlich wärmer ist als die Temperatur im Kabel. In einem solchen Fall könnte es sonst vorkommen, dass die Wärmeübertragung vom Innern des Kabels zu seiner Oberfläche die gewünschte Unterscheidung beeinträchtigt oder unmöglich macht.An advantageous embodiment of the method according to the invention is characterized in that the marking is generated that the surface of the cable is cooled, and that the heat radiation of the cable in the new and the previous turn is detected. A cold mark is particularly advantageous if the cable surface when winding is significantly warmer than the temperature in the cable. In such a case, it could otherwise happen that heat transfer from the inside of the cable to its surface the desired distinction is impaired or impossible makes.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass zur Abkühlung Wasser verwendet wird, dessen Temperatur unterhalb der Raumtemperatur liegt. Wasser ist ein gefahrlos einsetzbares Medium für diesen Zweck. Another advantageous embodiment of the invention The method is characterized in that for cooling Water is used whose temperature is below room temperature lies. Water is a medium that can be used safely for this purpose.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass zur Abkühlung flüssiger Stickstoff verwendet wird, wodurch in vorteilhafter Weise in kürzester Zeit ein großer Temperaturunterschied zur Umgebung hergestellt werden kann, so dass die unterschiedlichen Wärmeabstrahlungen der verschiedenen Wicklungen deutlich erkennbar ist.Another advantageous embodiment of the invention The method is characterized in that for cooling Liquid nitrogen is used, which is beneficial Make a big temperature difference in no time Environment can be made so that the different Heat radiation from the different windings is clear is recognizable.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass die Markierung dadurch erzeugt wird, dass die Oberfläche des Kabels mit einem Stoff ausgerüstet wird, der nach entsprechender Anregung eine zeitlich abklingende Abstrahlung aufweist, und dass die Abstrahlung des Kabels an der neuen und der vorhergehenden Windung detektiert wird. Je nach der Art des Stoffes und seiner Anregung können die veränderungen der Abstrahlung in einem solchen Fall auch aus größerer Entfernung detektierbar sein.Another advantageous embodiment of the invention The method is characterized in that the marking is created by covering the surface of the cable with a Fabric is equipped after appropriate suggestion has a decaying radiation, and that the Radiation of the cable on the new and the previous one Turn is detected. Depending on the type of substance and its The changes in radiation can be stimulated in one such a case can also be detected from a greater distance his.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass als Ausrüstungsstoff Phosphor verwendet wird, der sich mit geringer Energie anregen läßt und eine genügend starke Abstrahlung aufweist.Another advantageous embodiment of the invention The method is characterized in that as a finishing material Phosphorus is used which is low energy can be stimulated and has a sufficiently strong radiation.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist schließlich dadurch gekennzeichnet, dass die Markierung dadurch erzeugt wird, dass die Oberfläche des Kabels mit einer Farbe beschichtet wird, die beim Austrocknen mit der Zeit ihre Farbe ändert, und dass die Farbe des Kabels in der neuen und der vorhergehenden Windung detektiert wird. Auch eine Farbänderung läßt sich aus größerer Entfernung detektieren wie auch die erwähnte Veränderung der Abstrahlung. Another advantageous embodiment of the invention Finally, the process is characterized in that the Marking is created by the surface of the cable is coated with a paint that dries out with time their color changes and that the color of the cable is detected in the new and the previous turn. A change in color can also be detected from a greater distance as well as the aforementioned change in radiation.

Zur Lösung der genannten Aufgabe ist eine Vorrichtung zur Durchführung des Verfahrens gekennzeichnet durch eine Markierungseinrichtung, die eine sich zeitlich verändernde Markierung auf das Kabel vor dem Aufwickeln desselben aufbringt, und durch ein Detektoreinrichtung, die den Zustand der Markierung wenigstens in der neuen und der vorhergehenden Windung detektiert, wobei die neue Windung von der vorhergehenden Windung zu unterscheiden ist. Die gestellte Aufgabe kann somit mit einem fast statischen Mittel gelöst werden.To achieve the above object, a device for Implementation of the method characterized by a marking device, which is a time-changing marker on the cable before winding it up, and by a detector device that detects the state of the mark at least in the new and the previous turn detected, the new turn from the previous one A distinction is to be made between the turns. The task can thus be solved with an almost static means.

Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Vorrichtung ist gekennzeichnet durch eine Heizeinrichtung, die die Oberfläche des Kabels erwärmt, und durch einen Wärmedetektor, der die Wärmeabstrahlung des Kabels in der neuen und der vorhergehenden Windung detektiert. Derartige Heizeinrichtungen und Wärmedetektoren sind gängige Bauteile, die mit geringen Kosten eingesetzt werden können.An advantageous embodiment of the device according to the invention is characterized by a heater that the surface of the cable is heated, and by a heat detector, the heat radiation of the cable in the new and the previous turn is detected.

Als Heizeinrichtungen sind Heizmanschetten und dergleichen denkbar. Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Vorrichtung ist jedoch dadurch gekennzeichnet, dass als Heizeinrichtung ein Infrarotstrahler und als Detektor ein Infrarotsensor vorgesehen sind.

This device stands out advantageously by high security and low Operating costs.

An embodiment of the invention will now be described with reference to the accompanying drawings. Show it:
Figure 1
a side view of a partially sectioned cable drum with a cable, a marking device and a detector device; and
Figure 2
is a schematic representation of a cable drum with a coiled cable in a first winding position.

Figur 1 zeigt in teilweise geschnittener Seitenansicht ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung zum spaltenfreien Aufwickeln eines Kabels 2 auf einer Kabeltromme1 4. Die Kabeltrommel 4 hat eine Trommel 6 und einen Flansch 8. Bei dem ankommenden Kabel 2 ist eine Markierungseinrichtung 10 vorgesehen, die eine Markierung auf das Kabel 2 aufbringt. Eine Detektoreinrichtung 12 detektiert den Zustand der Markierung wenigstens in der neuen Windung 2' (Figur 2) und der vorhergehenden Windung 2", wie durch das Detektionsfenster 14 in Figur 2 angedeutet ist.Figure 1 shows a partially sectioned side view Embodiment of the device according to the invention gap-free winding of a cable 2 on a cable drum 1 4. The cable drum 4 has a drum 6 and one Flange 8. There is a marking device on the incoming cable 2 10 provided a mark on the cable 2 applies. A detector device 12 detects the state the marking at least in the new turn 2 '(FIG 2) and the previous turn 2 ", as through the detection window 14 is indicated in Figure 2.

Je nach der Art der Markierung kann die Markierungseinrichtung 10 eine Heizeinrichtung, eine Kühleinrichtung, eine Einrichtung, die die Oberfläche des Kabels mit einem Stoff ausrüstet, der nach entsprechender Anregung eine zeitlich abklingende Abstrahlung aufweist, oder eine Farb-Beschichtungseinrichtung sein. Entsprechend ist die Detektoreinrichtung 12 auf den Markierungsstoff abgestimmt und detektiert die Wärmeabstrahlung der Kabelwindungen 2', 2", eine sonstige Abstrahlung, beispielsweise Phosphoreszenz, oder die Farbe der Windungen 2', 2".Depending on the type of marking, the marking device 10 a heating device, a cooling device, a device, that finishes the surface of the cable with a fabric, which, after the appropriate suggestion, decays in time Has radiation, or a color coating device his. The detector device 12 is correspondingly matched to the marking substance and detects the heat radiation the cable turns 2 ', 2 ", another radiation, for example phosphorescence, or the color of the Turns 2 ', 2 ".

Wenn, wie in diesem Ausführungsbeispiel, die Kabeltrommel 4 in ihrer Achsrichtung bewegt wird, um eine Wickellage auf der Trommel 6 zu erzeugen, sind die Markierungseinrichtung 10 und die Detektoreinrichtung 12 ortsfest über dem ankommenden Kabel 2 angeordnet. Wenn andererseits die Kabeltrommel 4 ortsfest angeordnet ist, können die Markierungseinrichtung 10 und die Detektoreinrichtung 12 mit dem ankommenden Kabel 2 mitbewegt werden.If, as in this embodiment, the cable drum 4 is moved in its axial direction to a winding position on the To produce drum 6 are the marking device 10 and the detector device 12 is stationary over the incoming cable 2 arranged. On the other hand, if the cable drum 4 is stationary is arranged, the marking device 10 and the detector device 12 moves with the incoming cable 2 become.

Wenn beim Bewickeln die aktuell entstehende Kabelwindung den Trommelflansch 8 oder den anderen Trommelflansch 16 (Figur 2) erreicht, wird das Kabel in dieser flanschnahen Position gehalten, bis die Kabeltrommel ca. 320 Grad in Aufwickelrichtung weitergedreht hat. Daran anschließend wird das auflaufende Kabel um den Abstand eines Kabeldurchmessers vom Flansch entfernt positioniert. Ab diesem Zeitpunkt wird wieder die Aufwickelposition so geregelt, dass das auflaufende Kabel, welches, wenn die Markierungseinrichtung 10 eine Heizeinrichtung ist, die höchste Temperatur hat, seitenrichtig neben dem zweitwärmsten Kabel zu liegen kommt. Dieser Übergang berücksichtigt die Tatsache, dass die Windung, die über die letzte Windung an dem Flansch gewickelt wird, die darunter liegende Windung abdeckt, so dass die unmittelbare Reihenfolge der beiden Windungen in diesem Augenblick nicht festgestellt beziehungsweise detektiert werden kann.If the current winding of the cable during winding Drum flange 8 or the other drum flange 16 (FIG. 2) reached, the cable is held in this position close to the flange, until the cable drum is about 320 degrees in the winding direction has continued to shoot. Then the accumulating Cable by the distance of a cable diameter from the Flange positioned away. From that point on again the winding position is regulated so that the accumulating Cable, which if the marker 10 is a heater is, the highest temperature, right side comes to lie next to the second warmest cable. This transition takes into account the fact that the turn that over the last turn is wound on the flange, the one below covering lying turn, so the immediate order of the two turns at this moment can be determined or detected.
