Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Aufwickeln von Rundmaterial auf eine mit Endflanschen versehene Spule mit Hilfe einer Anordnung zum Drehen und axialen Verschieben der Spule sowie einer radial am Umfang der Spule anliegenden, axial verschiebbaren Anpreß-einrichtung. Das erfindungsgemäße Verfahren und die Vorrichtung sind dabei besonders für starkes, relativ schwer biegbares Rundmaterial wie starke Rundddrähte oder Kabel geeignet, können in gleicher Weise jedoch auch bei dünneren Materialien zur Anwendung kommen.The invention relates to a method and a device for winding round material onto a spool provided with end flanges with the aid of an arrangement for rotating and axially displacing the spool and an axially displaceable pressing device which lies radially on the circumference of the spool. The method and the device according to the invention are particularly suitable for strong, relatively difficult to bend round material such as strong round wires or cables, but can also be used in the same way for thinner materials.

Beim Aufwickeln von Rundmaterial ist es wichtig, das Material so zu verlegen, daß ein dichter und gleichmäßiger Wickel mit optimalem Füllgrad entsteht als Voraussetzung für eine knickfreie Aufspulung und eine einwandfreie Abwickelbarkeit des Rundmaterials. Dies läßt sich nur dadurch erreichen, daß das Rundmaterial dicht aneinander und genau in die Windungsrille der darunterliegenden Lage gelegt wird.When winding round material, it is important to lay the material in such a way that a tight and even winding with an optimal filling level is created as a prerequisite for kink-free winding and perfect unwinding of the round material. This can only be achieved by placing the round material close together and precisely in the winding groove of the underlying layer.

In der US-PS 4,202,512, die den Stand der Technik und den Oberbegriff des Anspruchs 3 bildet, ist eine Aufwickelvorrichtung gezeigt, die am Umfang einer sich drehenden Spule ein Führungsmittel zur Führung des sich aufwickelnden Drahtes aufweist. Das Führungsmittel drückt dabei die Wicklungen des Drahtes dicht zusammen. Nachteilig an diesem Gerät ist, daß die Umlenkrolle auf einer Achse gleitend gelagert ist und es daher durch Abnutzung oder/und Verschmutzungen zu einer Verklemmung kommen kann, sodaß eine dauerhafte sichere Führung des Drahtes nicht gewährleistet ist. Kommt es zu einer Abweichung des Winkels von 90°, so tritt beim Aufwickeln auf die Spule zwischen der letzten Wicklung und der neuen Wicklung erhöhte Reibung auf, was einen Verschleiß des Drahtes bedingt.In US-PS 4,202,512, which forms the prior art and the preamble of claim 3, a winding device is shown, which has a guide means for guiding the winding wire on the circumference of a rotating spool. The guide means presses the windings of the wire together tightly. A disadvantage of this device is that the deflection roller is slidably mounted on an axis and jamming and / or contamination can therefore result in jamming, so that permanent, secure guidance of the wire is not guaranteed. If the angle deviates by 90 °, increased friction occurs between the last winding and the new winding when winding onto the coil, which causes wear on the wire.

In der DE-OS 2 437 295 ist eine Wickelvorrichtung gezeigt, bei der mittels einer Geschwindigkeits-Regeleinrichtung versucht wird, das dichte Anliegen der einzelnen Wicklungen zu steuern. Die Regeleinrichtung umfaßt dabei Fühler, die zur Erfassung der Lage des Drahtes vorgesehen sind, über die die axiale Vorschubgeschwindigkeit der Trommel gesteuert wird. Zwar sorgt hier die axiale Verschiebung der Trommel für ein einigermaßen gleichmäßiges Anliegen der einzelnen Wicklungen aneinander, aber es ist nicht möglich mit dieser Vorrichtung, ein enges Anliegen der Spulenwicklungen aneiander zu gewährleisten, da kein Führungsmittel zur Führung des sich aufwickelnden Drahtes vorgesehen ist.DE-OS 2 437 295 shows a winding device in which an attempt is made to control the tightness of the individual windings by means of a speed control device. The control device includes sensors which are provided for detecting the position of the wire, by means of which the axial feed speed of the drum is controlled. Although the axial displacement of the drum ensures that the individual windings lie against one another to some extent, it is not possible with this device to ensure that the coil windings fit tightly against one another, since no guide means is provided for guiding the winding wire.

Bekannte Einrichtungen mit einer hin und her bewegbaren Führung, die das Rundmaterial nur dem Aufwickelverlauf folgend leiten, bieten keine Gewähr dafür, daß beim Übergang von einer Lage in die nächsthöhere das Rundmaterial nicht klemmt und zuverlässig in die Windungsrille der vorherigen Lage gelegt wird.Known devices with a back and forth guide that guide the round material only following the winding process do not guarantee that the round material will not jam when moving from one layer to the next higher one and will be reliably placed in the winding groove of the previous layer.

Der Erfindung liegt die Aufgabe zugrunde, die Mittel anzugeben, die ein zuverlässiges und genaues Aufwickeln von Rundmaterial, insbesondere von solchem mit größerem Durchmesser, gewährleisten.The invention has for its object to provide the means that ensure a reliable and accurate winding of round material, especially those with a larger diameter.

Die Aufgabe wird verfahrensmäßig durch die Merkmale des Patentanspruchs 1 gelöst. Eine zur Lösung der Aufgabe geeignete Vorrichtung ist Gegenstand des Anspruchs 3. Vorteilhafte Ausgestaltungen ergeben sich aus den Ansprüchen 2 und 4 bis 9.The task is solved procedurally by the features of claim 1. A device suitable for achieving the object is the subject of claim 3. Advantageous refinements result from claims 2 and 4 to 9.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen:

  • Fig. 1 eine perspektivische Darstellung der wichtigsten Teile der erfindungsgemäßen Vorrichtung,
  • Fig. 2a und 2b schematisch den Ablauf des Aufwickelvorgangs.
The invention is explained in more detail below with reference to an embodiment shown in the drawing. The drawing shows:
  • 1 is a perspective view of the most important parts of the device according to the invention,
  • 2a and 2b schematically the course of the winding process.

Die Wickelvorrichtung besteht im wesentlichen aus einem durch eine Verstelleinrichtung 1 geführten Wickelmotor 2, der, ggfs. unter Zwischenschaltung eines Getriebes, zur Aufnahme der Wickelspule 3 dient. In Umlaufrichtung hinter dem Berührungspunkt des Rundmaterials auf der Spule liegt eine Anpreßrolle 5 federnd an dem Rollenumfang an. Die Halterung der Rolle 5 ist als Verstelleinheit 4 ausgebildet, mittels der die Rolle 5 parallel zur Achse der Spule 3 verschoben werden kann. Die Rolle 5 hat die Form einer Kreisscheibe und liegt mit ihrem Umfang an der Wickelspule 3 bzw. der untersten Lage des Rundmaterials, mit einer ihrer Seitenflächen seitlich an dem aufgewickelten Rundmaterial an.The winding device essentially consists of a winding motor 2 which is guided by an adjusting device 1 and which, if necessary with the interposition of a gear, serves to receive the winding spool 3. In the direction of rotation behind the point of contact of the round material on the spool, a pressure roller 5 rests resiliently on the circumference of the roller. The holder of the roller 5 is designed as an adjustment unit 4, by means of which the roller 5 can be moved parallel to the axis of the coil 3. The roller 5 has the shape of a circular disc and lies with its circumference on the winding spool 3 or the lowest layer of the round material, with one of its side surfaces on the side of the wound round material.

Das aufzuwickelnde Rundmaterial 8 wird von einem Vorrat über eine feststehende Rolle 6 zugeführt. Zwischen der Rolle 6 und der Wickelspule 3 befinden sich unter dem zulaufenden Rundmaterial zwei Sensoren 7, die ein Signal an eine Rechen- und Steuereinheit abgeben, wenn sich das Rundmaterial infolge seitlicher Auslenkung über einem der Sensoren befindet.The round material 8 to be wound is fed from a supply via a fixed roller 6. Between the roll 6 and the winding spool 3 there are two sensors 7 under the incoming round material, which emit a signal to a computing and control unit when the round material is located above one of the sensors due to lateral deflection.

Der Aufwickelvorgang ist schematisch in den Fig. 2a und 2b in den aufeinanderfolgenden Phasen dargestellt. Der untere Teil der Darstellung zeigt dabei eine Aufsicht senkrecht auf das zulaufende Rundmaterial, der obere Teil eine Ansicht senkrecht dazu gegen die Richtung des zulaufenden Rundmaterials. Die axialen Verschiebebewegungen der Wickelspule 3 und der Anpreßrolle 5 sind dabei durch Pfeile angedeutet.The winding process is shown schematically in FIGS. 2a and 2b in the successive phases. The lower part of the illustration shows a view perpendicular to the incoming round material, the upper part a view perpendicular to the direction of the incoming round material. The axial displacement movements of the winding spool 3 and the pressure roller 5 are indicated by arrows.

In der Ausgangssituation befindet sich die Spule in der Position (1), in der das von der Rolle 6 kommende Rundmaterial 8 ohne Abstand zur Innenseite des Spulenflansches im rechten Winkel zur Spulenachse geführt ist und in einer dafür vorgesehenen Bohrung am Spulenflansch befestigt werden kann. Die Anpreßrolle 5 wird axial bis zum Abstand eines Materialdurchmessers an den Spulenflansch bewegt und dort radial an den Spulenkern gedrückt. Sodann wird der Drehantrieb der Wickelspule eingeschaltet und mit dem Aufwickeln begonnen.In the initial situation, the bobbin is in position (1), in which the round material 8 coming from the roll 6 is guided at a right angle to the bobbin axis without any clearance to the inside of the bobbin flange and can be fastened in a bore provided on the bobbin flange. The pressure roller 5 is moved axially up to the distance of a material diameter on the spool flange and pressed radially there on the spool core. The rotary drive of the winding spool is then switched on and winding begins.

Gemäß Position (2) wird zu Beginn des Aufwickelns die Anpreßrolle 5 den aufgewickelten Windungen folgend verschoben, und zwar um einen Weg pro Spulenumdrehung, der dem Durchmesser des Rundmaterials entspricht. Die Wickelspule steht dabei in axialer Richtung fest. Alternativ kann sie aber auch in zur Anpreßrolle entgegengesetzter Richtung verschoben werden, jedoch mit geringerer Geschwindigkeit als die Anpreßrolle. Deren Verchiebegeschwindigkeit muß in diesem Fall so eingestellt sein, daß die Summe der Verschiebungen von Wickelspule und Anpreßrolle pro Spulenumdrehung gleich dem Materialdurchmesser ist.According to position (2), the pressure roller 5 is shifted following the coiled windings at the beginning of the winding, namely by one path per spool revolution, which corresponds to the diameter of the round material. The winding spool is fixed in the axial direction. Alternatively, it can also be moved in the opposite direction to the pressure roller, but at a lower speed than the pressure roller. In this case, their displacement speed must be set so that the sum of the displacements of the winding spool and pressure roller per spool revolution is equal to the material diameter.

Durch die Anpassung der Verschiebung von Anpreßrolle und/oder Wickelspule an den Materialdurchmesser wird dem zulaufenden Material für die folgenden Windungen nur ein Abstand, der dem Materialdurchmesser entspricht, zur Verfügung gestellt, so daß die Windungen seitlich dicht aneinanderliegend ohne seitlichen Zwischenraum aufgewickelt werden.By adapting the displacement of the pressure roller and / or winding spool to the material diameter, the incoming material for the following turns is only a distance that corresponds to the material diameter, so that the turns are wound side by side without any space between them.

Wegen der stillstehenden oder langsamer als dem Zulauf entsprechend verschobenen Wickelspule ändert sich der ursprünglich rechte Winkel zwischen der Spulenachse und dem von der Rolle 6 kommenden Rundmaterial. In Position (3) hat der Winkel einen Wert erreicht, bei dem der in der Darstellung linke Sensor aktiviert wird. Das von dem Sensor ausgehende Signal bewirkt, daß die Verschiebung der Anpreßrolle unterbrochen und der Verschiebeantrieb der Wickelspule aktiviert wird, und zwar in einer zur Verschiebung der Anpreßrolle entgegengesetzten Richtung (in den unteren Darstellungen nach rechts). Die Verschiebegeschwindigkeit ist dabei größer als eine Materialbreite pro Spulenumdrehung. Bei bereits in Position (2) erfolgender langsamerer Verschiebung der Wickelspule wird die Geschwindigkeit in Position (3) entsprechend erhöht.Because the winding bobbin is stationary or displaced more slowly than the inlet, the originally right angle between the bobbin axis and the round material coming from the roll 6 changes. In position (3) the angle has reached a value at which the sensor shown on the left is activated. The signal emanating from the sensor has the effect that the displacement of the pressure roller is interrupted and the displacement drive of the winding spool is activated in a direction opposite to the displacement of the pressure roller (to the right in the lower illustrations). The displacement speed is greater than a material width per spool revolution. If the winding spool is shifted more slowly in position (2), the speed in position (3) is increased accordingly.

Durch die schnellere Verschiebung der Wickelspule wird die Winkeländerung rückgängig gemacht und der Sensor deaktiviert. Dadurch wird die Verschiebung der Anpreßrolle wieder aufgenommen und die der Wickelspule stillgesetzt (oder verlangsamt). Der bisherige Vorgang wiederholt sich so oft, bis der lichte Abstand zwischen der Anpreßrolle und dem anderen Spulenflansch das 1,5fache des Materialdurchmessers beträgt.The faster movement of the winding spool reverses the change in angle and deactivates the sensor. As a result, the displacement of the pressure roller is resumed and that of the winding spool is stopped (or slowed down). The previous process is repeated until the clear distance between the pressure roller and the other spool flange is 1.5 times the material diameter.

Zu diesem in Position (4) dargestellten Zeitpunkt wird die Verschieberichtung der Anpreßrolle umgekehrt und diese in gleicher Richtung wie die Wickelspule bewegt, und zwar mit einer der Materialdicke pro Spulenumdrehung entsprechenden Geschwindigkeit. Das hat zur Folge, daß der Abstand zwischen der Anpreßrolle und dem Spulenflansch konstant bleibt, jedoch kein Platz mehr für das zur Spule laufende Material neben der Anpreßrolle zur Verfügung gestellt wird. Dadurch wird das Material unter die Anpreßrolle gedrückt bzw. diese durch das Material angehoben wird und die folgenden Windungen werden unter der Anpreßrolle aufgewickelt (Position 5)).At this time, shown in position (4), the direction of displacement of the pressure roller is reversed and it is moved in the same direction as the winding spool, with one corresponding to the material thickness per spool revolution Speed. The result of this is that the distance between the pressure roller and the spool flange remains constant, but no more space is made available for the material running to the spool next to the pressure roller. This pushes the material under the pressure roller or it is lifted by the material and the following turns are wound up under the pressure roller (position 5)).

In Position (6) hat das Material unter der Anpreßrolle den anderen Spulenflansch erreicht. Die gleichgerichtete Verschiebung von Wickelspule und Anpreßrolle wird jetzt erhöht und so lange beibehalten, bis das von der Rolle 6 kommende Material im rechten Winkel zur Spulenachse zuläuft. Dann wird die Spulenverschiebung ausgeschaltet und die Verschiebung der Anpreßrolle für eine Spulenumdrehung angehalten. Dadurch wird das Material über die bereits vorhandene Windung der ersten Lage gewickelt und wegen des Abstandes der Anpreßrolle um den 1,5fachen Materialdurchmesser von dem Spulenflansch in die Windungsrille zwischen der letzten und der vorletzten Windung der ersten Lage gelegt.In position (6) the material has reached the other spool flange under the pressure roller. The rectified shift of the winding spool and the pressure roller is now increased and maintained until the material coming from the roller 6 runs at a right angle to the spool axis. Then the spool shift is turned off and the shift of the pressure roller is stopped for one spool revolution. As a result, the material is wound over the already existing turn of the first layer and, because of the distance of the pressure roller, is placed 1.5 times the material diameter from the coil flange into the winding groove between the last and the penultimate turn of the first layer.

Hiernach wird in Position (7) die Verstelleinrichtung 4 für die Anpreßrolle wieder eingeschaltet und mit der Wicklung der zweiten Lage begonnen. In Position (8) ist durch die Auslenkung des Materials der andere Sensor aktiviert worden, der eine Verschiebung der Wickelspule bzw. eine Erhöhung der Verschiebegeschwindigkeit nach links bewirkt.Thereafter, the adjustment device 4 for the pressure roller is switched on again in position (7) and the winding of the second layer is started. In position (8), the deflection of the material has activated the other sensor, which causes the winding spool to shift or to increase the shifting speed to the left.

Das Aufwickeln wird in dieser Weise mit wechselnden Seitenrichtungen fortgesetzt.The winding is continued in this way with changing lateral directions.
