Definitions
- the invention relates to a method for producing a coil assembly by means of a winding machine, wherein a wire is wound onto a winding pin of a winding assembly of the winding machine to produce a coil of the coil assembly.
- the invention also relates to a corresponding winding machine for producing such a coil arrangement.
- Such a method and such a winding machine are for example from the EP 2 237 292 A2 .
- a disadvantage of known methods for producing coils or corresponding winding machines is that the coil to be produced must begin at a free end of the wire. Consequently, the coil can not be formed into a piece of wire, one side of which is already part of an electrical component and the other side on one Reel is rolled up.
- the individual coils In order to produce, for example, with known methods an arrangement of several series-connected coils, the individual coils must be manufactured separately from each other and electrically connected after their preparation, for example by soldering. The production of these electrical connections is complicated and error-prone, so that coil arrangements produced by the known methods or known winding machines are relatively expensive and have a high failure rate.
- the object of the present invention is to provide a method of manufacturing a coil arrangement which makes it possible to mold an electrical coil into a piece of wire whose free ends can not be accessed. This object is achieved by a method according to claim 1 and a winding machine according to claim 6.
- a method according to claim 1 wherein from a first wire portion of the wire, a first part winding of the coil is produced by the winding pin is wound according to a first winding sense with the first wire portion and from a second wire portion of the wire, a second part of the winding Coil is produced by the winding pin is wound in accordance with a second winding direction opposite to the first winding sense with the second wire section.
- the coil produced by this method thus comprises two partial windings which are wound in opposite winding sense.
- a partial winding for example the first partial winding runs from the outside inwards (towards a longitudinal axis of the coil) and the other partial winding, for example the second partial winding, from inside to outside (away from the longitudinal axis of the coil).
- a current flowing through the wire of the coil Therefore, in both partial windings has the same direction of rotation with respect to the central axis of the coil. Therefore, despite the different Wickelsinne with the coil, a magnetic flux can be generated.
- Dividing the coil into the two partial windings ensures that it is not necessary to access a free end of the wire in order to mold the coil into the wire.
- the coil can also be formed in such a wire whose first end is for example part of an already manufactured component, for example another coil, and whose other free end is still on a reel or reel.
- a coil assembly having multiple serially connected coils can be made from a single piece of wire.
- the individual coils need not be made of different pieces of wire and then electrically connected together. With the method, therefore, the operation of the electrical connection of the individual coils can be saved, which allows a cost-effective production of the coil assembly and excludes the electrical connections between the coils as a cause for a failure of the coil assembly.
- a middle portion of the wire between the two wire sections is fixed to the winding pin. According to the method, therefore, the winding of the two partial windings is started at the central region. Consequently, a free end of the wire need not be accessed.
- the winding pin is rotated about its longitudinal axis in order to wind it with the first wire section.
- the winding machine has a wire feed arrangement, and that during manufacture of the first part of the winding winding winding is rotated relative to the wire feed arrangement of the winding machine that the resulting from the rotational movements peripheral speeds are the same size on the winding pin, so that when producing the first part winding , the winding pin is only wound by the first wire section.
- the winding arrangement and the winding pin are rotated about at least substantially parallel axes of rotation. This prevents that during winding of the first part of the winding winding simultaneously, the second wire section is wound in the same sense as the first wire section.
- the rotation of the winding pin is prevented about its longitudinal axis and the winding assembly is rotated relative to the wire feed arrangement of the winding machine, so that the winding pin is wrapped by the second wire section due to the rotation of the winding assembly relative to the wire feed arrangement.
- the manufacture of the coil is divided into two steps.
- the first step the first partial winding is produced from the first wire section, wherein the winding arrangement and the winding pin rotate in opposite directions.
- the winding arrangement is further rotated so that the second partial winding is produced from the second wire section.
- a plurality of coils are produced from a single piece of wire by successively winding a plurality of winding pins each having a first wire section and a second wire section.
- a coil arrangement with a plurality of coils can be produced particularly easily, wherein each coil comprises a first partial winding and a second partial winding.
- an end of the first wire section facing away from the central region has a fixed spatial reference to the winding arrangement and the winding pin is moved towards the end of the first wire section, preferably along a straight line, while the winding pin is wound with the first wire section.
- the winding pin is moved towards the end of the first wire section, preferably along a straight line, while the winding pin is wound with the first wire section.
- the end of the first wire section is held at a fixed location, while moving during winding of the first partial winding of the winding pin to the end of the wire section.
- the coil to be produced can be particularly easily attached to a component, for example another coil, in which the wire is installed.
- the coil arrangement with a plurality of coils connected in series can be produced easily.
- a counterforce is generated which counteracts a movement of the winding pin.
- an actuator which is pneumatically or electrically driven, for example, can be provided.
- a spring for generating the counterforce can also be used.
- the winding pin is locked after moving to the end of the first wire portion in an end position corresponding to a predetermined position of the coil within the coil assembly. This ensures that, for example, when producing the coil arrangement with a plurality of coils connected in series, the individual coils are positioned with sufficient accuracy relative to one another. Thus, the required for the manufacture of coil assemblies for electric motors tolerances with respect to the geometry of the coil assembly can be met.
- the same actuator may be provided, which is also set up to generate the opposing force.
- the actuator is driven so that it generates the counterforce, whereas it is driven after reaching the end position so that it counteracts any movement of the winding pin away from the end position.
- the end position is predetermined by a mechanical stop or the like and the winding pin is held by appropriate control of a pneumatic actuator, for example a compressed air cylinder, in this predetermined position.
- a winding machine having a winding arrangement which is adapted to wind a wire on a winding pin to produce a spool of the spool assembly, the winding machine being arranged to consist of a first Wire portion of the wire to produce a first part winding of the coil, in which the winding pin is wound according to a first winding sense with the first wire portion and a second wire portion of the wire to produce a second partial winding of the coil by the winding pin is wound according to a second winding direction opposite to the first winding sense with the second wire section.
- the winding arrangement has a plate rotatably mounted about a main axis of rotation on which at least one winding pin, preferably in a radial direction relative to the main axis of rotation, is slidably mounted. Due to the displaceable mounting it is achieved that, as described above, the winding pin can be moved toward the end of the first wire section during the production of the first partial winding. This movement can, as described above, be controlled by means of an actuator.
- the winding machine has a wire feed arrangement which is arranged such that the rotation of the plate about the main axis of rotation leads to a rotation of the winding pin around the wire feed arrangement.
- the second partial winding can be manufactured according to the second winding direction and / or the first partial winding can be prevented from being wound according to the first winding direction during the production of the first partial winding.
- the wire feed arrangement is fastened to a movable linkage so as to counteract the movement of the winding pin as a result of the rotation of the plate and / or can follow the displacement of the winding pin towards the end of the first wire section. Despite the movement of the winding pins, the wire feed arrangement thus always remains in the vicinity of the winding pin.
- the winding machine has guide means which cooperate with the winding pin and / or the wire feed means such that the wire feeding means follow the movement of the winding pin due to the rotation of the disk and / or the shifting of the winding pin towards the end of the first wire section.

Since the winding pin 23 is mounted displaceably in a radial direction with respect to the main axis of rotation 49, the winding pin 23 moves during the winding of the first wire section 55 along a radial direction of movement (arrow 61 in FIG FIG. 4 ). When the first part winding 59 is finished, the winding pin 23 is in an in FIG. 4 Dashed line end position 63.

Description
Die Erfindung betrifft ein Verfahren zum Herstellen einer Spulenanordnung mit Hilfe einer Wickelmaschine, wobei ein Draht auf einen Wickelpin einer Wickelanordnung der Wickelmaschine aufgewickelt wird, um eine Spule der Spulenanordnung herzustellen. Die Erfindung betrifft außerdem eine entsprechende Wickelmaschine zum Herstellen einer solchen Spulenanordnung.The invention relates to a method for producing a coil assembly by means of a winding machine, wherein a wire is wound onto a winding pin of a winding assembly of the winding machine to produce a coil of the coil assembly. The invention also relates to a corresponding winding machine for producing such a coil arrangement.
Ein derartiges Verfahren und eine derartige Wickelmaschine sind beispielsweise aus der
Es ist allgemein bekannt, Spulen, insbesondere für Elektromotoren, maschinell herzustellen. Beim maschinellen Herstellen einer Spule wird ein Stück Draht auf einem rotierenden Wickelpin aufgewickelt. Sobald eine gewünschte Zahl an Windungen aufgewickelt worden ist, wird der Draht abgeschnitten, und die Spule ist hergestellt.It is well known to machine coils, especially for electric motors. When machining a coil, a piece of wire is wound on a rotating winding pin. Once a desired number of turns has been wound up, the wire is cut off and the spool is made.
Nachteilig an bekannten Verfahren zum Herstellen von Spulen beziehungsweise entsprechenden Wickelmaschinen ist, dass die herzustellende Spule an einem freien Ende des Drahtes beginnen muss. Folglich kann die Spule nicht in ein Stück Draht eingeformt werden, dessen eine Seite bereits Teil eines elektrischen Bauteils ist und dessen andere Seite auf einer Haspel aufgerollt ist. Um beispielsweise mit bekannten Verfahren eine Anordnung aus mehreren in Serie geschalteten Spulen herzustellen, müssen die einzelnen Spulen getrennt voneinander hergestellt werden und nach ihrer Herstellung elektrisch, beispielsweise durch Löten miteinander verbunden werden. Das Herstellen dieser elektrischen Verbindungen ist aufwändig und fehleranfällig, so dass mit den bekannten Verfahren beziehungsweise bekannten Wickelmaschinen hergestellte Spulenanordnungen relativ teuer sind und eine hohe Ausfallrate aufweisen.A disadvantage of known methods for producing coils or corresponding winding machines is that the coil to be produced must begin at a free end of the wire. Consequently, the coil can not be formed into a piece of wire, one side of which is already part of an electrical component and the other side on one Reel is rolled up. In order to produce, for example, with known methods an arrangement of several series-connected coils, the individual coils must be manufactured separately from each other and electrically connected after their preparation, for example by soldering. The production of these electrical connections is complicated and error-prone, so that coil arrangements produced by the known methods or known winding machines are relatively expensive and have a high failure rate.
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zum Herstellen einer Spulenanordnung zu schaffen, das es ermöglicht, in ein Stück Draht, auf dessen freie Enden nicht zugegriffen werden kann, eine elektrische Spule einzuformen. Diese Aufgabe wird durch ein Verfahren gemäß Anspruch 1 und eine Wickelmaschine gemäß Anspruch 6 gelöst.The object of the present invention is to provide a method of manufacturing a coil arrangement which makes it possible to mold an electrical coil into a piece of wire whose free ends can not be accessed. This object is achieved by a method according to claim 1 and a winding machine according to claim 6.
In einer Ausführungsform ist ein Verfahren gemäss Anspruch 1 vorgesehen, wobei aus einem ersten Drahtabschnitt des Drahts eine erste Teilwicklung der Spule hergestellt wird, indem der Wickelpin gemäß einem ersten Wickelsinn mit dem ersten Drahtabschnitt bewickelt wird und aus einem zweiten Drahtabschnitt des Drahts eine zweite Teilwicklung der Spule hergestellt wird, indem der Wickelpin gemäß einem dem ersten Wickelsinn entgegengesetzten zweiten Wickelsinn mit dem zweiten Drahtabschnitt bewickelt wird. Die mit diesem Verfahren hergestellte Spule umfasst also zwei Teilwicklungen, die in entgegengesetztem Wickelsinn gewickelt sind. Bezogen auf eine Längsrichtung des Drahts verläuft jedoch eine Teilwicklung, beispielsweise die erste Teilwicklung von außen nach innen (zu einer Längsachse der Spule hin) und die andere Teilwicklung, beispielsweise die zweite Teilwicklung, von innen nach außen (von der Längsachse der Spule weg). Ein durch den Draht der Spule fließender Strom weist deshalb in beiden Teilwicklungen dieselbe Drehrichtung bezogen auf die Mittelachse der Spule auf. Deshalb kann trotz der unterschiedlichen Wickelsinne mit der Spule ein magnetischer Fluss erzeugt werden.In one embodiment, a method according to claim 1 is provided, wherein from a first wire portion of the wire, a first part winding of the coil is produced by the winding pin is wound according to a first winding sense with the first wire portion and from a second wire portion of the wire, a second part of the winding Coil is produced by the winding pin is wound in accordance with a second winding direction opposite to the first winding sense with the second wire section. The coil produced by this method thus comprises two partial windings which are wound in opposite winding sense. With respect to a longitudinal direction of the wire, however, a partial winding, for example the first partial winding runs from the outside inwards (towards a longitudinal axis of the coil) and the other partial winding, for example the second partial winding, from inside to outside (away from the longitudinal axis of the coil). A current flowing through the wire of the coil Therefore, in both partial windings has the same direction of rotation with respect to the central axis of the coil. Therefore, despite the different Wickelsinne with the coil, a magnetic flux can be generated.
Durch das Aufteilen der Spule in die beiden Teilwicklungen wird erreicht, dass nicht auf ein freies Ende des Drahtes zugegriffen werden muss, um die Spule in den Draht einzuformen. Somit kann die Spule auch in einen solchen Draht eingeformt werden, dessen erstes Ende beispielsweise Teil eines bereits hergestellten Bauteils ist, beispielsweise einer anderen Spule, und dessen anderes freies Ende sich noch auf eine Rolle oder Haspel befindet. Somit kann aus einem einzigen Stück Draht eine Spulenanordnung mit mehreren in Serie geschalteten Spulen hergestellt werden. Anders als bei bekannten Verfahren müssen die einzelnen Spulen nicht aus unterschiedlichen Drahtstücken hergestellt werden und anschließend elektrisch miteinander verbunden werden. Mit dem Verfahren kann also der Arbeitsgang des elektrischen Verbindens der einzelnen Spulen eingespart werden, was eine kostengünstige Herstellung der Spulenanordnung ermöglicht und die elektrischen Verbindungen zwischen den Spulen als Ursache für einen Ausfall der Spulenanordnung ausschließt.Dividing the coil into the two partial windings ensures that it is not necessary to access a free end of the wire in order to mold the coil into the wire. Thus, the coil can also be formed in such a wire whose first end is for example part of an already manufactured component, for example another coil, and whose other free end is still on a reel or reel. Thus, a coil assembly having multiple serially connected coils can be made from a single piece of wire. Unlike known methods, the individual coils need not be made of different pieces of wire and then electrically connected together. With the method, therefore, the operation of the electrical connection of the individual coils can be saved, which allows a cost-effective production of the coil assembly and excludes the electrical connections between the coils as a cause for a failure of the coil assembly.
Es wird ein mittlerer Bereich des Drahts zwischen den beiden Drahtabschnitten an dem Wickelpin fixiert. Gemäß dem Verfahren wird also an dem mittleren Bereich mit dem Wickeln der beiden Teilwicklungen begonnen. Folglich muss nicht auf ein freies Ende des Drahts zugegriffen werden. Beim Herstellen der ersten Teilwicklung wird der Wickelpin um seine Längsachse rotiert, um ihn mit dem ersten Drahtabschnitt zu bewickeln.A middle portion of the wire between the two wire sections is fixed to the winding pin. According to the method, therefore, the winding of the two partial windings is started at the central region. Consequently, a free end of the wire need not be accessed. When the first part winding is produced, the winding pin is rotated about its longitudinal axis in order to wind it with the first wire section.
Weiter ist vorgesehen, dass die Wickelmaschine eine Drahtzuführungsanordnung aufweist, und dass beim Herstellen der ersten Teilwicklung die Wickelanordnung gegenüber der Drahtzuführungsanordnung der Wickelmaschine derart rotiert wird, dass die aus den Drehbewegungen resultierenden Umfangsgeschwindigkeiten am Wickelpin gleich groß gewählt werden, so dass beim Herstellen der ersten Teilwicklung, der Wickelpin lediglich vom ersten Drahtabschnitt bewickelt wird. Vorzugsweise werden die Wickelanordnung und der Wickelpin um zumindest im Wesentlichen parallel zueinander verlaufende Drehachsen rotiert. Hierdurch wird verhindert, dass beim Wickeln der ersten Teilwicklung gleichzeitig der zweite Drahtabschnitt im selben Wickelsinn wie der erste Drahtabschnitt gewickelt wird.It is further provided that the winding machine has a wire feed arrangement, and that during manufacture of the first part of the winding winding winding is rotated relative to the wire feed arrangement of the winding machine that the resulting from the rotational movements peripheral speeds are the same size on the winding pin, so that when producing the first part winding , the winding pin is only wound by the first wire section. Preferably, the winding arrangement and the winding pin are rotated about at least substantially parallel axes of rotation. This prevents that during winding of the first part of the winding winding simultaneously, the second wire section is wound in the same sense as the first wire section.
Weiter ist vorgesehen, dass beim Herstellen der zweiten Teilwicklung die Rotation des Wickelpins um seine Längsachse unterbunden wird und die Wickelanordnung gegenüber der Drahtzuführungsanordnung der Wickelmaschine rotiert wird, so dass der Wickelpin von dem zweiten Drahtabschnitt infolge der Rotation der Wickelanordnung gegenüber der Drahtzuführungsanordnung umwickelt wird. Auf diese Weise wird die Herstellung der Spule in zwei Schritte unterteilt. Im ersten Schritt wird aus dem ersten Drahtabschnitt die erste Teilwicklung hergestellt, wobei sich die Wickelanordnung und der Wickelpin in entgegengesetzten Richtungen drehen. In einem zweiten Schritt wird die Wickelanordnung weiter rotiert, so dass aus dem zweiten Drahtabschnitt die zweite Teilwicklung hergestellt wird.It is further provided that during the production of the second partial winding, the rotation of the winding pin is prevented about its longitudinal axis and the winding assembly is rotated relative to the wire feed arrangement of the winding machine, so that the winding pin is wrapped by the second wire section due to the rotation of the winding assembly relative to the wire feed arrangement. In this way, the manufacture of the coil is divided into two steps. In the first step, the first partial winding is produced from the first wire section, wherein the winding arrangement and the winding pin rotate in opposite directions. In a second step, the winding arrangement is further rotated so that the second partial winding is produced from the second wire section.
In einer besonders bevorzugten Ausführungsform ist vorgesehen, dass mehrere Spulen aus einem Stück Draht hergestellt werden, indem nacheinander mehrere Wickelpins mit jeweils einem ersten Drahtabschnitt und einem zweiten Drahtabschnitt bewickelt werden. Durch die Verwendung mehrerer Wickelpins kann besonders einfach eine Spulenanordnung mit mehreren Spulen hergestellt werden, wobei jede Spule eine erste Teilwicklung und eine zweite Teilwicklung umfasst.In a particularly preferred embodiment, it is provided that a plurality of coils are produced from a single piece of wire by successively winding a plurality of winding pins each having a first wire section and a second wire section. By using a plurality of winding pins, a coil arrangement with a plurality of coils can be produced particularly easily, wherein each coil comprises a first partial winding and a second partial winding.
Es ist bevorzugt, dass ein vom mittleren Bereich abgewandtes Ende des ersten Drahtabschnitts einen festen räumlichen Bezug zu der Wickelanordnung aufweist und der Wickelpin zum Ende des ersten Drahtabschnitts, vorzugsweise entlang einer Geraden hin bewegt wird, während der Wickelpin mit dem ersten Drahtabschnitt bewickelt wird. Bei dem Verfahren wird also nicht der Wickelpin, sondern das Ende des ersten Drahtabschnitts an einem festen Ort gehalten, während sich beim Wickeln der ersten Teilwicklung der Wickelpin zu dem Ende des Drahtabschnitts hin bewegt. Auf diese Weise kann die herzustellende Spule besonders einfach an ein Bauteil, beispielsweise einer anderen Spule, in das der Draht verbaut ist, angefügt werden. Somit lässt sich insbesondere die Spulenanordnung mit mehreren in Serie geschalteten Spulen einfach herstellen.It is preferred that an end of the first wire section facing away from the central region has a fixed spatial reference to the winding arrangement and the winding pin is moved towards the end of the first wire section, preferably along a straight line, while the winding pin is wound with the first wire section. In the method, therefore, not the winding pin, but the end of the first wire section is held at a fixed location, while moving during winding of the first partial winding of the winding pin to the end of the wire section. In this way, the coil to be produced can be particularly easily attached to a component, for example another coil, in which the wire is installed. Thus, in particular, the coil arrangement with a plurality of coils connected in series can be produced easily.
Um die erste Teilwicklung mit einer guten Qualität herstellen zu können, ist bevorzugt, dass eine Gegenkraft erzeugt wird, die einer Bewegung des Wickelpins entgegenwirkt. Zum Erzeugen dieser Gegenkraft kann ein Aktor, der beispielsweise pneumatisch oder elektrisch angetrieben ist, vorgesehen sein. Alternativ oder ergänzend hierzu kann auch eine Feder zum Erzeugen der Gegenkraft eingesetzt werden.In order to be able to produce the first partial winding with a good quality, it is preferred that a counterforce is generated which counteracts a movement of the winding pin. To generate this counterforce, an actuator which is pneumatically or electrically driven, for example, can be provided. Alternatively or additionally, a spring for generating the counterforce can also be used.
Weiter ist bevorzugt, dass der Wickelpin nach dem Bewegen zum Ende des ersten Drahtabschnitts hin in einer Endposition arretiert wird, die einer vorgegebenen Lage der Spule innerhalb der Spulenanordnung entspricht. Hierdurch wird sichergestellt, dass beispielsweise beim Herstellen der Spulenanordnung mit mehreren in Serie geschalteten Spulen die einzelnen Spulen hinreichend genau relativ zueinander positioniert sind. Somit können die zum Herstellen von Spulenanordnungen für Elektromotoren erforderlichen Toleranzen bezüglich der Geometrie der Spulenanordnung eingehalten werden. Zum Arretieren des Wickelpins in seiner Endposition kann beispielsweise derselbe Aktor vorgesehen sein, der auch zum Erzeugen der Gegenkraft eingerichtet ist. Während des Bewegens des Wickelpins zum Ende des ersten Drahtabschnitts hin wird der Aktor so angesteuert, dass er die Gegenkraft erzeugt, wohingegen er nach dem Erreichen der Endposition so angesteuert wird, dass er jeder Bewegung des Wickelpins von der Endposition weg entgegenwirkt. Es ist denkbar, dass die Endposition durch einen mechanischen Anschlag oder dergleichen vorgegeben wird und der Wickelpin durch entsprechende Ansteuerung eines pneumatischen Aktors, beispielsweise eines Druckluftzylinders, in dieser vorgegebenen Position gehalten wird.Further, it is preferred that the winding pin is locked after moving to the end of the first wire portion in an end position corresponding to a predetermined position of the coil within the coil assembly. This ensures that, for example, when producing the coil arrangement with a plurality of coils connected in series, the individual coils are positioned with sufficient accuracy relative to one another. Thus, the required for the manufacture of coil assemblies for electric motors tolerances with respect to the geometry of the coil assembly can be met. For locking the winding pin in its end position, for example, the same actuator may be provided, which is also set up to generate the opposing force. During movement of the winding pin toward the end of the first wire section, the actuator is driven so that it generates the counterforce, whereas it is driven after reaching the end position so that it counteracts any movement of the winding pin away from the end position. It is conceivable that the end position is predetermined by a mechanical stop or the like and the winding pin is held by appropriate control of a pneumatic actuator, for example a compressed air cylinder, in this predetermined position.
Gemäß einer weiteren Ausführungsform der Erfindung ist eine Wickelmaschine gemäss Anspruch 6 vorgesehen, wobei die Wickelmaschine eine Wickelanordnung aufweist, die dazu eingerichtet ist, einen Draht auf einen Wickelpin aufzuwickeln, um eine Spule der Spulenanordnung herzustellen, wobei die Wickelmaschine dazu eingerichtet ist, aus einem ersten Drahtabschnitt des Drahts eine erste Teilwicklung der Spule herzustellen, in dem der Wickelpin gemäß einem ersten Wickelsinn mit dem ersten Drahtabschnitt bewickelt wird und aus einem zweiten Drahtabschnitt des Drahts eine zweite Teilwicklung der Spule herzustellen, indem der Wickelpin gemäß einem dem ersten Wickelsinn entgegengesetzten zweiten Wickelsinn mit dem zweiten Drahtabschnitt bewickelt wird.According to a further embodiment of the invention, there is provided a winding machine according to claim 6, wherein the winding machine has a winding arrangement which is adapted to wind a wire on a winding pin to produce a spool of the spool assembly, the winding machine being arranged to consist of a first Wire portion of the wire to produce a first part winding of the coil, in which the winding pin is wound according to a first winding sense with the first wire portion and a second wire portion of the wire to produce a second partial winding of the coil by the winding pin is wound according to a second winding direction opposite to the first winding sense with the second wire section.
Es ist vorgesehen, dass die Wickelanordnung eine um eine Hauptdrehachse drehbar gelagerte Platte aufweist, auf der mindestens ein Wickelpin, vorzugsweise in einer radialen Richtung bezüglich der Hauptdrehachse, verschiebbar gelagert ist. Durch die verschiebbare Lagerung wird erreicht, dass der Wickelpin, wie oben beschrieben, beim Herstellen der ersten Teilwicklung zum Ende des ersten Drahtabschnitts hin bewegt werden kann. Diese Bewegung kann, wie oben beschrieben, mit Hilfe eines Aktors kontrolliert werden.It is provided that the winding arrangement has a plate rotatably mounted about a main axis of rotation on which at least one winding pin, preferably in a radial direction relative to the main axis of rotation, is slidably mounted. Due to the displaceable mounting it is achieved that, as described above, the winding pin can be moved toward the end of the first wire section during the production of the first partial winding. This movement can, as described above, be controlled by means of an actuator.
Weiter ist vorgesehen, dass die Wickelmaschine eine Drahtzuführungsanordnung aufweist, die derart angeordnet ist, dass die Drehung der Platte um die Hauptdrehachse zu einer Rotation des Wickelpins um die Drahtzuführungsanordnung herum führt. Somit kann durch die Drehung der Platte die zweite Teilwicklung gemäß dem zweiten Wickelsinn hergestellt werden und/oder beim Herstellen der ersten Teilwicklung verhindert werden, dass der zweite Drahtabschnitt gemäß dem ersten Wickelsinn gewickelt wird.It is further provided that the winding machine has a wire feed arrangement which is arranged such that the rotation of the plate about the main axis of rotation leads to a rotation of the winding pin around the wire feed arrangement. Thus, by the rotation of the plate, the second partial winding can be manufactured according to the second winding direction and / or the first partial winding can be prevented from being wound according to the first winding direction during the production of the first partial winding.
Um bei der Herstellung der Spule beziehungsweise der Spulenanordnung den Draht gezielt zuführen zu können und eine gleichmäßige Bewicklung zu bewirken, ist bevorzugt, dass die Drahtzuführungsanordnung an einem beweglichen Gestänge befestigt ist, so dass sie der Bewegung des Wickelpins infolge der Drehung der Platte und/oder dem Verschieben des Wickelpins zum Ende des ersten Drahtabschnitts hin folgen kann. Trotz der Bewegung des Wickelpins bleibt die Drahtzuführungsanordnung also immer in der Nähe des Wickelpins.In order to be able to supply the wire in a targeted manner during the production of the coil or of the coil arrangement and to effect a uniform winding, it is preferred that the wire feed arrangement is fastened to a movable linkage so as to counteract the movement of the winding pin as a result of the rotation of the plate and / or can follow the displacement of the winding pin towards the end of the first wire section. Despite the movement of the winding pins, the wire feed arrangement thus always remains in the vicinity of the winding pin.
Hierbei ist besonders bevorzugt, dass die Wickelmaschine Führungsmittel aufweist, die mit dem Wickelpin und/oder den Drahtzuführungsmittel derart zusammenwirken, dass die Drahtzuführungsmittel der Bewegung des Wickelpins infolge der Drehung der Platte und/oder dem Verschieben des Wickelpins zum Ende des ersten Drahtabschnitts hin folgen. Die Führungsmittel können beispielsweise einen Mitnehmer aufweisen, wobei ein erster Mitnehmerabschnitt des Wickelpins in einen zweiten Mitnehmerabschnitt der Drahtzuführungsanordnung eingreifen oder auf sonstige Weise
mit diesem zusammenwirken kann, um die Drahtzuführungsanordnung der Bewegung des Wickelpins folgen zu lassen.In this case, it is particularly preferred that the winding machine has guide means which cooperate with the winding pin and / or the wire feed means such that the wire feeding means follow the movement of the winding pin due to the rotation of the disk and / or the shifting of the winding pin towards the end of the first wire section. The guide means may for example comprise a driver, wherein a first driver portion of the winding pins engage in a second driver portion of the wire feed arrangement or otherwise
can cooperate with this to follow the wire feed arrangement of the movement of the winding pin.

Die Platte 15 ist Teil einer Wickelanordnung 21 der Wickelmaschine 11. Die Wickelanordnung 21 weist mindestens einen Wickelpin 23, vorzugsweise mehrere, insbesondere sechs Wickelpins 23, auf, die auf der Platte 15 in bezüglich einer Hauptdrehachse der Platte 15 radialer Richtung verschiebbar befestigt sind. Die verschiebbare Befestigung der Wickelpins 23 kann beispielsweise mittels Schieber 25 erreicht werden, wobei jedem Wickelpin 23 jeweils ein solcher Schieber 25 zugeordnet ist. Jedem Schieber 25 bzw. Wickelpin 23 kann ein Aktor 27 mit einem pneumatischen Antrieb 29 zugeordnet sein. An Stelle des pneumatischen Antriebs 29 kann auch ein elektromagnetischer Antrieb vorgesehen sein. Es ist auch denkbar, an Stelle des Aktors 27 oder zusätzlich zum Aktor 27 eine Feder vorzusehen, die auf den jeweiligen Wickelpin 23 eine Kraft ausübt, die in Richtung zur Hauptdrehachse wirkt.The
Des Weiteren weist die Wickelmaschine 11 eine Drahtzuführungsanordnung 31 auf, die dazu eingerichtet ist, beim Wickeln von Spulen dem jeweiligen Wickelpin 23 Draht zuzuführen und eine Drahtführung beim Wickeln auf den Wickelpin 23 sicherzustellen.

Mit dem Verfahren bzw. der Wickelmaschine 11 können deshalb insbesondere Spulenanordnungen 51 für Elektromotoren mit scheibenförmigen Spulen hergestellt werden.In summary, the winding
