Definitions
- the invention relates to a device and a method for winding toroidal cores arranged in a toroidal core plane with a wire arranged in a winding plane.
- a toroidal coil winding device with a toroidal core holder and an annular magazine guided through the toroidal core opening with elements used for guiding and storing wires is, for example, from FIG DE 101 53 896 A1 famous.
- a disadvantage of this known device is that the wire to be wound onto the toroidal core during operation exerts a high load on the toroidal core when a wire turn is generated, since the wire is wound directly onto the toroidal core. In particular with toroidal cores with low material strength and when wrapping with a thick wire, this can lead to material failure of the toroidal core.
- Another toroidal core winding device with a toroidal core holder and a magazine-free wire guide is for example from the EP 2 953 149 B1 famous.
- a disadvantage of this known device is that the wire to be wound onto the toroidal core during operation exerts a high load on the toroidal core when a wire turn is generated, since the wire is wound directly onto the toroidal core. In particular with toroidal cores with low material strength and when wrapping with a thick wire, this can lead to material failure of the toroidal core.
- the present invention is therefore based on the object of creating a device for winding toroidal cores and a corresponding winding method which enable the automated winding of toroidal cores with, in particular, comparatively low material strength.
- the device should have a simple and robust structure and should be inexpensive to manufacture.
- the invention provides a device for winding toroidal cores arranged in a toroidal core plane with a wire arranged in a winding plane, the apparatus comprising a protective cover, which is arranged essentially in the toroidal core plane and perpendicular to the winding plane and is mounted horizontally translationally movable in the toroidal core plane and is set up to be guided over the toroidal core in areas during operation and thereby protect the toroidal core and to create an inner shape of at least one wire turn on which the wire is wound.
- the device further comprises a slide which is arranged essentially in the toroidal core plane and parallel to the protective cover and is mounted slidably around the protective cover and surrounds the protective cover in some areas and is designed to move the at least one wire winding wound onto the protective cover during operation by a translational movement from the protective cover onto the toroidal core.
- a method for winding toroidal cores arranged in a toroidal core plane with a wire arranged in a winding plane comprises winding the wire onto a protective cover and furthermore the following steps: advancing a slide and pushing the at least one wire turn from the protective cover onto the toroidal core; and pushing back the slide.
- the method also includes the above-mentioned preceding step of positioning and braking the wire to be wound by means of guide plates.
- a wire turn is generated on the protective cover that protects the toroidal core during operation, in that the protective cover generates an inner shape of at least one wire turn on which the wire is wound. Furthermore, the at least one wire turn wound on the protective cover is deposited during operation according to the invention by a translational movement of the slide against the wire turn from the protective cover onto the toroidal core. As a result, the load during the generation of the wire winding is absorbed by the protective cover. Since the toroidal core thus experiences essentially no load during the generation of the wire winding, toroidal cores with, in particular, a comparatively low material strength can also be wound or wires with a comparatively larger wire diameter can also be wound.
- the device according to the invention has a simple structure, since further precautions that enable the winding of toroidal cores with low material strength can be dispensed with. Due to the relatively simple structure, the device is also robust and inexpensive to manufacture. The method according to the invention thus allows automated winding of toroidal cores with, in particular, comparatively low material strength, which cannot be wound with conventional toroidal core (coil) winding devices.
- the invention In comparison to conventional toroidal core winding devices with a magazine, the invention has a simple structure, since further precautions that enable toroidal cores with low material strength to be wound can be dispensed with. Due to the relatively simple structure, the device is also robust and inexpensive to manufacture. The method according to the invention thus allows automated winding of toroidal cores with, in particular, comparatively low material strength, which cannot be wound with conventional toroidal core winding devices.
- the protective cover comprises a receiving area in an area essentially opposite the end face of the toroidal core, which is designed to receive an area of the toroidal core that is already wound with the wire.
- the receiving area is formed by the geometry of the protective cover between the end face of the toroidal core and the protective cover in order to prevent a collision with the partially wound toroidal core during operation.
- the slide comprises a receiving area in an area essentially opposite the end face of the toroidal core, which is designed to receive an area of the toroidal core already wound with the wire.
- the receiving area is formed by the geometry of the slide between the end face of the toroidal core and the slide in order to prevent a collision with the partially wound toroidal core during operation. This enables the toroidal core to be wound automatically. As a result, the process time for winding the toroidal core can be reduced and the quality of the wound toroidal core can be increased.
- the device comprises a first guide plate and a second guide plate, which are arranged essentially parallel to the winding plane and are designed to guide and brake the wire in a predetermined position in the winding plane before being wound onto the protective cover.
- the wire should preferably be guided in the winding plane.
- the wire is guided on the protective cover between the first guide plate and the second guide plate in the winding plane.
- the wire located in between is braked by friction. This reduces the load on the protective cover when the wire is wrapped and prevents the wire from tearing off. In addition, this increases the quality of the wire winding produced.
- the first guide plate is mounted in a stationary manner and the second guide plate is mounted such that it can move horizontally in the toroidal core plane.
- the wire strikes the first guide plate and the second guide plate and moves the second guide plate away from the first guide plate.
- the wire is guided between the first guide plate and the second guide plate into a position in the winding plane that is advantageous for producing a wire turn. This enables the device to be used for wires with different wire thicknesses and an increase in the quality of the wire winding produced.
- the first guide plate and the second guide plate have an incline in an upper region which continuously increases the distance between the first guide plate and the second guide plate and forms a funnel-shaped wire guide region.
- the wire hits the first guide plate and the second guide plate, the wire is passed through the funnel-shaped wire guide area between the first guide plate and the second guide plate is guided into the winding plane.
- the wire is also guided from a position outside the winding plane into a position between the first guide plate and the second guide plate in the winding plane that is advantageous for generating a wire turn, and the process reliability is thereby increased.
- the second (or also the first or both) guide plate (s) preferably has a surface with braking properties which is designed to brake the wire before it is wound onto the protective cover when the wire is guided between the guide plates.
- the braking property can be achieved, for example, in that the second guide plate has a surface made of a material (e.g. felt) with a coefficient of friction which is higher than the coefficient of friction of the first guide plate.
- the surface of one or both guide plates is correspondingly coated or processed in such a way that the desired coefficient of friction is achieved.
- the first guide plate and the second guide plate comprise receiving areas which are designed to receive the toroidal core, the protective cover and the slide.
- the receiving areas of the first guide plate and the second guide plate allow a compact and robust design of the device.
- the device comprises at least two drive rollers with recesses each arranged on the end face of the drive rollers, which are arranged essentially parallel and adjacent to the toroidal core and are designed to place the wire windings on the toroidal core take up and drive the toroidal core in rotation. Due to the parallel and adjacent arrangement of the drive rollers, the toroidal core is stored in a stationary manner during operation. At least one of the drive rollers is driven in rotation and, during operation, transmits the rotary movement to the toroidal core. The cutouts in the drive rollers take wire turns already wound on the toroid during operation in order to avoid a collision and also to ensure the transmission of the rotary movement when the toroid has already been partially wound.
- the protective cover and the slider are designed in a mirrored manner on the winding plane. This design allows toroidal cores to be wound in both directions of rotation and can thus shorten the winding cycle time.
- the device 1000 for winding toroidal cores 2000 preferably has a protective cover 1100 which surrounds and protects the toroidal core 2000 in areas during operation.
- the protective cover 1100 is arranged essentially in the toroidal core plane 4100 and perpendicular to the winding plane 4200.
- the protective cover 1100 is mounted in the toroidal core plane 4100 such that it can move horizontally in translation and can be guided over the toroidal core 2000 in areas.
- the area of the protective cover 1100 which is guided over the toroidal core 2000 during operation has a U-shaped inner shape corresponding to the outer shape of the toroidal core 2000.
- the outer shape of the protective cover 1100 corresponds to the inner shape of at least one wire turn 3100.
- the protective cover 1100 surrounds the toroidal core 2000 in areas during operation in order to protect the toroidal core 2000 while the wire 3000 is being wound. During the winding, the wire 3000 is wound on the protective cover 1100.
- the protective cover 1100 is preferably made of a material with a material strength that is higher than the material strength of the toroidal core 2000.
- the device 1000 for winding toroidal cores 2000 further comprises a slide 1200 which, during operation, pushes the at least one wire winding 3100 wound onto the protective cover 1100 from the protective cover 1100 onto the toroidal core 2000.
- the slide 1200 is arranged essentially in the toroidal core plane 4100 and parallel to the protective cover 1100 and is mounted so as to be slidable around the protective cover 1100.
- the inner shape of the slide 1200 which is arranged over the protective cover 1100 during operation, corresponds to the outer shape of the protective cover 1100.
- the slide 1200 is in an initial position during the winding of the protective cover 1100, as in FIG Figure 4a is shown.
- the slider 1200 moves in the direction of the wire turn 3100 and pushes the wire turn 3100 from the protective cover 1100 onto the toroidal core 2000, as in FIG Fig. 4b shown. After the slider 1200 has pushed the at least one wire turn 3100 from the protective cover 1100 onto the toroidal core 2000, the slider 1200 moves back into the starting position, which enables the wire 3000 to be further wrapped around the protective cover 1100.
- the protective cover 1100 and the slide 1200 include receiving areas 1110, 1210 which are arranged in an area essentially opposite the end face of the toroidal core 2000, as in FIG Fig. 2 shown.
- the receiving areas 1110, 1210 are set up to receive an area of the ring core 2000 that has already been wound with the wire 3000 during operation. This prevents the already wound area of the ring core 2000 from colliding with the protective cover 1100 or the slide 1200 during operation.
- the illustrated first and second guide plates 1310, 1320 are arranged essentially parallel and adjacent to the winding plane 4200.
- the first guide plate 1310 is mounted in a stationary manner and the second guide plate 1320 is mounted in the toroidal core plane 4100 so that it can move horizontally in a translatory manner.
- the guide plates 1310, 1320 guide the wire 3000 into a predetermined position in the winding plane 4200 and brake the wire 3000 before it is wound onto the protective cover 1100.
- the first guide plate 1310 and the second guide plate 1320 have inclines in an upper region 1330, which the Continuously increase the distance between the first guide plate 1310 and the second guide plate 1320 and form a funnel-shaped wire opening area 1340.
- the wire 3000 When the wire 3000 hits the first guide plate 1310 and the second guide plate 1320, the wire 3000 is guided through the funnel-shaped wire opening area 1340 by moving the second guide plate 1320 between the first guide plate 1310 and the second guide plate 1320. The wire 3000 is thus also guided from a position outside the winding plane 4200 into a position in the winding plane 4200 that is advantageous for generating at least one wire turn 3100. The wire 3000 is guided between the first guide plate 1310 and the second guide plate 1320 into a position in the winding plane 4200 that is advantageous for producing the wire winding 3100.
- the wire 3000 between the first guide plate 1310 and the second guide plate 1320 is braked on the one hand by a restoring force which acts from the second guide plate 1320 in the direction of the first guide plate 1310.
- the wire 3000 located in between is pressed by the second guide plate 1320 against the first guide plate 1310 and thereby braked when the wire 3000 is guided between the guide plates 1310, 1320.
- the second guide plate 1320 according to an embodiment of the present invention has a surface 1322 with braking properties made of a material (e.g. provided with a brake lining such as felt or the like) with a coefficient of friction that is higher than the coefficient of friction of the first guide plate 1310, as in FIG Fig. 1 shown.
- the wire 3000 is also braked by the increased friction between the wire 3000 and the second guide plate 1320 due to the surface 1322 with braking properties.
- the first guide plate 1310 or both guide plates 1310, 1320 can also be mounted in a translationally movable manner.
- the first guide plate 1310 or both guide plates 1310, 1320 can have a surface 1322 with braking properties.
- the device 1000 comprises at least two drive rollers 1410, 1420 with recesses 1411, 1421 each arranged on the end face of the drive rollers 1410, 1420.
- the drive rollers 1410, 1420 are arranged on their end face adjacent to the toroidal core 2000 and drive the toroidal core 2000 rotatory on during winding.
- the recesses 1411, 1421 of the drive rollers 1410, 1420 are set up to receive the wire windings 3100 already wound on the toroidal core 2000 during operation. This ensures that the drive rollers 1410, 1420 do not collide with the wire windings 3100 wound on the toroidal core 2000 and that the rotational movement is also transmitted to the toroidal core 2000 when the toroidal core 2000 has already been partially wound.
- the method 5000 for winding toroidal cores 2000 can be performed as follows with reference to FIG Figure 4a , 4b and 5 can be summarized as described.
- the toroidal core 2000 is inserted into the device 1000 and rotated during winding.
- the protective cover 1100 is guided over the toroidal core 2000 in some areas, whereby the toroidal core 2000 is mounted in a preferred position in the device 1000 in a fixed and rotationally movable manner by the drive rollers 1410, 1420 and the protective cover 1100.
- a first turn of wire 3100 is wound on the protective cover 1100, as in FIG Figure 4a shown.
- the slide 1200 moves in the direction of the wire turn 3100 and pushes it from the protective cover 1100 onto the toroidal core 2000.
- the slide 1200 then moves back into its original position. These steps are repeated until a predetermined desired number of turns of wire 3100 is wound on the toroidal core 2000.
- the method 5000 for winding toroidal cores 2000 can, in addition to the steps described above, also include a preceding step of positioning and braking the wire 3000 to be wound by means of guide plates 1310, 1320.
- the wire 3000 hits the first guide plate 1310 and the second guide plate 1320, the wire 3000 is guided through the funnel-shaped wire opening area 1340 between the first guide plate 1310 and the second guide plate 1320.
- the guide plates 1310, 1320 guide the wire 3000 into a predetermined position in the winding plane 4200 and brake the wire 3000 before it is wound onto the protective cover 1100.
- FIG. 5 shows a flowchart of an embodiment of a method 5000 for winding toroidal cores 2000 according to an embodiment of the present invention.
- step 5100 the toroidal core 2000 is inserted into the device 1000 before the winding.
- the protective cover 1100 is guided over the toroidal core 2000, as a result of which the toroidal core 2000 is mounted in a stationary and rotationally movable manner by the drive rollers 1410, 1420 and the protective cover 1100.

Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Bewickeln von in einer Ringkernebene angeordneten Ringkernen mit einem in einer Wickelebene angeordneten Draht.The invention relates to a device and a method for winding toroidal cores arranged in a toroidal core plane with a wire arranged in a winding plane.

Eine weitere Ringkernen-Wickelvorrichtung mit einer Ringkernhalterung und einer magazinlosen Drahtführung ist beispielsweise aus der
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Bewickeln von Ringkernen sowie ein entsprechendes Wickelverfahren zu schaffen, die ein automatisiertes Bewickeln von Ringkernen mit insbesondere vergleichsweiser geringer Materialfestigkeit ermöglichen. Zusätzlich soll die Vorrichtung einfach und robust aufgebaut und kostengünstig herstellbar sein.The present invention is therefore based on the object of creating a device for winding toroidal cores and a corresponding winding method which enable the automated winding of toroidal cores with, in particular, comparatively low material strength. In addition, the device should have a simple and robust structure and should be inexpensive to manufacture.
Zur Lösung dieser Aufgabe sieht die Erfindung eine Vorrichtung zum Bewickeln von in einer Ringkernebene angeordneten Ringkernen mit einem in einer Wickelebene angeordneten Draht vor, wobei die Vorrichtung eine Schutzabdeckung umfasst, welche im Wesentlichen in der Ringkernebene und senkrecht zu der Wickelebene angeordnet und in der Ringkernebene horizontal translatorisch beweglich gelagert ist und dazu eingerichtet ist, im Betrieb bereichsweise über den Ringkern geführt zu werden und den Ringkern dadurch zu schützen und eine innere Form von zumindest einer Drahtwindung zu erzeugen, auf die der Draht gewickelt wird. Die Vorrichtung umfasst ferner einen Schieber, welcher im Wesentlichen in der Ringkernebene und parallel zu der Schutzabdeckung angeordnet und um die Schutzabdeckung gleitbar gelagert ist und die Schutzabdeckung bereichsweise umgibt und dazu eingerichtet ist, die zumindest eine auf die Schutzabdeckung gewickelte Drahtwindung im Betrieb durch eine translatorische Bewegung von der Schutzabdeckung auf den Ringkern zu schieben.To achieve this object, the invention provides a device for winding toroidal cores arranged in a toroidal core plane with a wire arranged in a winding plane, the apparatus comprising a protective cover, which is arranged essentially in the toroidal core plane and perpendicular to the winding plane and is mounted horizontally translationally movable in the toroidal core plane and is set up to be guided over the toroidal core in areas during operation and thereby protect the toroidal core and to create an inner shape of at least one wire turn on which the wire is wound. The device further comprises a slide which is arranged essentially in the toroidal core plane and parallel to the protective cover and is mounted slidably around the protective cover and surrounds the protective cover in some areas and is designed to move the at least one wire winding wound onto the protective cover during operation by a translational movement from the protective cover onto the toroidal core.
Zur Lösung der Aufgabe wird weiterhin ein Verfahren zum Bewickeln von in einer Ringkernebene angeordneten Ringkernen mit einem in einer Wickelebene angeordneten Draht vorgeschlagen. Das Verfahren umfasst dabei das Wickeln des Drahtes auf eine Schutzabdeckung und ferner folgende Schritte: Vorschieben eines Schiebers und Schieben der zumindest einen Drahtwindung von der Schutzabdeckung auf den Ringkern; und Rückschieben des Schiebers. In einer vorteilhaften Ausführungsform umfasst das Verfahren zudem einen den oben genannten vorgeschalteten Schritt des Positionierens und Bremsens des zu wickelnden Drahtes durch Führungsbleche.To achieve the object, a method for winding toroidal cores arranged in a toroidal core plane with a wire arranged in a winding plane is also proposed. The method comprises winding the wire onto a protective cover and furthermore the following steps: advancing a slide and pushing the at least one wire turn from the protective cover onto the toroidal core; and pushing back the slide. In an advantageous embodiment, the method also includes the above-mentioned preceding step of positioning and braking the wire to be wound by means of guide plates.
Das Erzeugung einer Drahtwindung erfolgt damit erfindungsgemäß auf der den Ringkern im Betrieb schützenden Schutzabdeckung, indem die Schutzabdeckung eine innere Form von zumindest einer Drahtwindung erzeugt, auf die der Draht gewickelt wird. Ferner erfolgt das Ablegen der zumindest einen auf die Schutzabdeckung gewickelten Drahtwindung im Betrieb erfindungsgemäß durch eine translatorische Bewegung des Schiebers gegen die Drahtwindung von der Schutzabdeckung auf den Ringkern. Dadurch wird die Belastung bei der Erzeugung der Drahtwindung von der Schutzabdeckung aufgenommen. Da somit der Ringkern während der Erzeugung der Drahtwindung im Wesentlichen keine Belastung erfährt, können auch Ringkerne mit insbesondere vergleichsweiser geringer Materialfestigkeit bewickelt bzw. auch Drähte mit vergleichsweise größerem Drahtdurchmesser gewickelt werden.According to the invention, a wire turn is generated on the protective cover that protects the toroidal core during operation, in that the protective cover generates an inner shape of at least one wire turn on which the wire is wound. Furthermore, the at least one wire turn wound on the protective cover is deposited during operation according to the invention by a translational movement of the slide against the wire turn from the protective cover onto the toroidal core. As a result, the load during the generation of the wire winding is absorbed by the protective cover. Since the toroidal core thus experiences essentially no load during the generation of the wire winding, toroidal cores with, in particular, a comparatively low material strength can also be wound or wires with a comparatively larger wire diameter can also be wound.
Im Vergleich zu einer herkömmlichen Ringkern(spulen)-Wickelvorrichtung mit einer Drahtführung ist die erfindungsgemäße Vorrichtung einfach aufgebaut, da auf weitere Vorkehrungen, die das Bewickeln von Ringkernen mit geringer Materialfestigkeit ermöglichen, verzichtet werden kann. Durch den relativ einfachen Aufbau ist die Vorrichtung ebenfalls robust und kostengünstig herzustellen. Das erfindungsgemäße Verfahren erlaubt somit ein automatisiertes Bewickeln auch von Ringkernen mit insbesondere vergleichsweiser geringer Materialfestigkeit, die mit herkömmlichen Ringkern(spulen)-Wickelvorrichtungen nicht wickelbar sind.In comparison to a conventional toroidal core (coil) winding device with a wire guide, the device according to the invention has a simple structure, since further precautions that enable the winding of toroidal cores with low material strength can be dispensed with. Due to the relatively simple structure, the device is also robust and inexpensive to manufacture. The method according to the invention thus allows automated winding of toroidal cores with, in particular, comparatively low material strength, which cannot be wound with conventional toroidal core (coil) winding devices.
Im Vergleich zu herkömmlichen Ringkern-Wickelvorrichtungen mit einem Magazin ist die Erfindung einfach aufgebaut, da auf weitere Vorkehrungen, die das Bewickeln von Ringkernen mit geringer Materialfestigkeit ermöglichen, verzichtet werden kann. Durch den relativ einfachen Aufbau ist die Vorrichtung ebenfalls robust und kostengünstig herzustellen. Das erfindungsgemäße Verfahren erlaubt somit ein automatisiertes Bewickeln auch von Ringkernen mit insbesondere vergleichsweiser geringer Materialfestigkeit, die mit herkömmlichen Ringkern-Wickelvorrichtungen nicht wickelbar sind.In comparison to conventional toroidal core winding devices with a magazine, the invention has a simple structure, since further precautions that enable toroidal cores with low material strength to be wound can be dispensed with. Due to the relatively simple structure, the device is also robust and inexpensive to manufacture. The method according to the invention thus allows automated winding of toroidal cores with, in particular, comparatively low material strength, which cannot be wound with conventional toroidal core winding devices.
Gemäß einem Aspekt umfasst die Schutzabdeckung einen Aufnahmebereich in einem der Stirnfläche des Ringkerns im Wesentlichen gegenüberliegenden Bereich, der dazu eingerichtet ist, einen bereits mit dem Draht bewickelten Bereich des Ringkerns aufzunehmen. Der Aufnahmebereich wird durch die Geometrie der Schutzabdeckung zwischen der Stirnfläche des Ringkerns und der Schutzabdeckung gebildet, um eine Kollision mit dem teilweise bewickelten Ringkern im Betrieb zu verhindern. Dies ermöglicht das automatisierte Bewickeln des Ringkerns. Dadurch kann die Prozesszeit zum Bewickeln des Ringkerns reduziert werden und die Qualität des bewickelten Ringkerns erhöht werden.According to one aspect, the protective cover comprises a receiving area in an area essentially opposite the end face of the toroidal core, which is designed to receive an area of the toroidal core that is already wound with the wire. The receiving area is formed by the geometry of the protective cover between the end face of the toroidal core and the protective cover in order to prevent a collision with the partially wound toroidal core during operation. This enables the toroidal core to be wound automatically. As a result, the process time for winding the toroidal core can be reduced and the quality of the wound toroidal core can be increased.
Gemäß einem weiteren Aspekt umfasst der Schieber einen Aufnahmebereich in einem der Stirnfläche des Ringkerns im Wesentlichen gegenüberliegenden Bereich, der dazu eingerichtet ist, einen bereits mit dem Draht bewickelten Bereich des Ringkerns aufzunehmen. Der Aufnahmebereich wird durch die Geometrie des Schiebers zwischen der Stirnfläche des Ringkerns und dem Schieber gebildet, um eine Kollision mit dem teilweise bewickelten Ringkern im Betrieb zu verhindern. Dies ermöglicht das automatisierte Bewickeln des Ringkerns. Dadurch kann die Prozesszeit zum Bewickeln des Ringkerns reduziert werden und die Qualität des bewickelten Ringkerns erhöht werden.According to a further aspect, the slide comprises a receiving area in an area essentially opposite the end face of the toroidal core, which is designed to receive an area of the toroidal core already wound with the wire. The receiving area is formed by the geometry of the slide between the end face of the toroidal core and the slide in order to prevent a collision with the partially wound toroidal core during operation. this enables the toroidal core to be wound automatically. As a result, the process time for winding the toroidal core can be reduced and the quality of the wound toroidal core can be increased.
Gemäß einem weiteren Aspekt umfasst die Vorrichtung ein erstes Führungsblech und ein zweites Führungsblech, welche im Wesentlichen parallel zu der Wickelebene angeordnet und dazu eingerichtet sind, den Draht vor dem Bewickeln auf die Schutzabdeckung in eine vorbestimmte Position in der Wickelebene zu führen und zu bremsen. Für die Erzeugung einer Drahtwindung auf der Schutzabdeckung ist der Draht vorzugsweise in der Wickelebene zu führen. Der Draht wird vor dem Bewickeln auf der Schutzabdeckung zwischen dem ersten Führungsblech und dem zweiten Führungsblech in der Wickelebene geführt. Durch eine Rückstellkraft des zweiten Führungsblechs in Richtung des ersten Führungsblechs wird der dazwischen befindliche Draht durch Reibung gebremst. Dadurch wird die Belastung auf die Schutzabdeckung bei der Bewicklung mit dem Draht reduziert und ein Abriss des Drahtes verhindert. Zudem wird dadurch die Qualität der erzeugten Drahtwindung erhöht.According to a further aspect, the device comprises a first guide plate and a second guide plate, which are arranged essentially parallel to the winding plane and are designed to guide and brake the wire in a predetermined position in the winding plane before being wound onto the protective cover. To create a wire winding on the protective cover, the wire should preferably be guided in the winding plane. Before being wound, the wire is guided on the protective cover between the first guide plate and the second guide plate in the winding plane. By a restoring force of the second guide plate in the direction of the first guide plate, the wire located in between is braked by friction. This reduces the load on the protective cover when the wire is wrapped and prevents the wire from tearing off. In addition, this increases the quality of the wire winding produced.
Gemäß einem weiteren Aspekt ist das erste Führungsblech ortsfest gelagert und das zweite Führungsblech in der Ringkernebene horizontal translatorisch beweglich gelagert. Bei der Erzeugung der Drahtwindung trifft der Draht auf das erste Führungsblech und das zweite Führungsblech und verschiebt das zweite Führungsblech weg von dem ersten Führungsblech. Dadurch wird der Draht zwischen dem ersten Führungsblech und dem zweiten Führungsblech in eine für die Erzeugung einer Drahtwindung vorteilhaften Position in der Wickelebene geführt. Dies ermöglicht die Anwendung der Vorrichtung für Drähte mit verschiedenen Drahtdicken und eine Erhöhung der Qualität der erzeugten Drahtwindung.According to a further aspect, the first guide plate is mounted in a stationary manner and the second guide plate is mounted such that it can move horizontally in the toroidal core plane. When the wire winding is produced, the wire strikes the first guide plate and the second guide plate and moves the second guide plate away from the first guide plate. As a result, the wire is guided between the first guide plate and the second guide plate into a position in the winding plane that is advantageous for producing a wire turn. This enables the device to be used for wires with different wire thicknesses and an increase in the quality of the wire winding produced.
Gemäß einem weiteren Aspekt weisen das erste Führungsblech und das zweite Führungsblech in einem oberen Bereich eine Neigung auf, welche den Abstand zwischen dem ersten Führungsblech und dem zweiten Führungsblech kontinuierlich erhöht und einen trichterförmigen Drahtführungsbereich bildet. Beim Auftreffen des Drahtes auf das erste Führungsblech und das zweite Führungsblech wird der Draht durch den trichterförmigen Drahtführungsbereich zwischen das erste Führungsblech und das zweite Führungsblech in die Wickelebene geführt. Dadurch wird der Draht auch aus einer Position außerhalb der Wickelebene in eine für die Erzeugung einer Drahtwindung vorteilhaften Position zwischen dem ersten Führungsblech und dem zweiten Führungsblech in der Wickelebene geführt und die Prozesssicherheit wird dadurch erhöht.According to a further aspect, the first guide plate and the second guide plate have an incline in an upper region which continuously increases the distance between the first guide plate and the second guide plate and forms a funnel-shaped wire guide region. When the wire hits the first guide plate and the second guide plate, the wire is passed through the funnel-shaped wire guide area between the first guide plate and the second guide plate is guided into the winding plane. As a result, the wire is also guided from a position outside the winding plane into a position between the first guide plate and the second guide plate in the winding plane that is advantageous for generating a wire turn, and the process reliability is thereby increased.
Gemäß einem weiteren Aspekt weist vorzugsweise das zweite (oder auch das erste oder beide) Führungsblech(e) eine Oberfläche mit Bremseigenschaften auf, die dazu eingerichtet ist, den Draht vor dem Bewickeln auf die Schutzabdeckung beim Führen des Drahtes zwischen den Führungsblechen zu bremsen. Die Bremseigenschaft kann beispielsweise erreicht werden, indem das zweite Führungsblech eine Oberfläche aus einem Material (z.B. Filz) mit einem Reibungskoeffizienten aufweist, der höher als der Reibungskoeffizient des ersten Führungsblechs ist. Gemäß weiterer Ausführungsformen ist die Oberfläche eines oder beider Führungsbleche entsprechend so beschichtet oder verarbeitet, dass der gewünschte Reibungskoeffizient erreicht wird. Beim Auftreffen des Drahtes auf das erste Führungsblech und das zweite Führungsblech und der Verschiebung des zweiten Führungsblechs wird der Draht durch die Rückstellkraft und die erhöhte Reibung zwischen dem Draht und dem zweiten Führungsblech gebremst. Dadurch wird sowohl die Belastung auf die Schutzabdeckung, als auch die Belastung auf das erste Führungsblech und das zweite Führungsblech bei der Bewicklung mit dem Draht reduziert und ein Abriss des Drahtes verhindert. Zudem wird dadurch die Qualität der erzeugten Drahtwindung erhöht.According to a further aspect, the second (or also the first or both) guide plate (s) preferably has a surface with braking properties which is designed to brake the wire before it is wound onto the protective cover when the wire is guided between the guide plates. The braking property can be achieved, for example, in that the second guide plate has a surface made of a material (e.g. felt) with a coefficient of friction which is higher than the coefficient of friction of the first guide plate. According to further embodiments, the surface of one or both guide plates is correspondingly coated or processed in such a way that the desired coefficient of friction is achieved. When the wire hits the first guide plate and the second guide plate and the displacement of the second guide plate, the wire is braked by the restoring force and the increased friction between the wire and the second guide plate. This reduces both the load on the protective cover and the load on the first guide plate and the second guide plate when the wire is wrapped, and prevents the wire from tearing off. In addition, this increases the quality of the wire winding produced.
Gemäß einem weiteren Aspekt umfassen das erste Führungsblech und das zweite Führungsblech Aufnahmebereiche, die dazu eingerichtet sind, den Ringkern, die Schutzabdeckung und den Schieber aufzunehmen. Die Aufnahmebereiche des ersten Führungsblechs und des zweiten Führungsblechs erlauben eine Kompakte und robuste Bauart der Vorrichtung.According to a further aspect, the first guide plate and the second guide plate comprise receiving areas which are designed to receive the toroidal core, the protective cover and the slide. The receiving areas of the first guide plate and the second guide plate allow a compact and robust design of the device.
Gemäß einem weiteren Aspekt umfasst die Vorrichtung zumindest zwei Antriebsrollen mit jeweils an der Stirnfläche der Antriebsrollen angeordneten Aussparungen, welche im Wesentlichen parallel und benachbart zu dem Ringkern angeordnet sind und dazu eingerichtet sind, die Drahtwindungen auf dem Ringkern aufzunehmen und den Ringkern rotatorisch anzutreiben. Durch die parallele und benachbarte Anordnung der Antriebsrollen wird der Ringkern im Betrieb ortsfest gelagert. Zumindest eine der Antriebsrollen ist rotatorisch angetrieben und überträgt im Betrieb die rotatorische Bewegung auf den Ringkern. Die Aussparungen der Antriebsrollen nehmen im Betrieb bereits gewickelte Drahtwindung auf dem Ringkern auf, um eine Kollision zu vermeiden und die Übertragung der rotatorischen Bewegung auch zu gewährleisten, wenn der Ringkern bereits teilweise bewickelt wurde.According to a further aspect, the device comprises at least two drive rollers with recesses each arranged on the end face of the drive rollers, which are arranged essentially parallel and adjacent to the toroidal core and are designed to place the wire windings on the toroidal core take up and drive the toroidal core in rotation. Due to the parallel and adjacent arrangement of the drive rollers, the toroidal core is stored in a stationary manner during operation. At least one of the drive rollers is driven in rotation and, during operation, transmits the rotary movement to the toroidal core. The cutouts in the drive rollers take wire turns already wound on the toroid during operation in order to avoid a collision and also to ensure the transmission of the rotary movement when the toroid has already been partially wound.
Gemäß einem weiteren Aspekt sind die Schutzabdeckung und der Schieber an der Wickelebene gespiegelt doppelt ausgeführt. Diese Ausführung erlaubt das Bewickeln von Ringkernen in beide Drehrichtungen und kann somit die Zykluszeit des Bewickelns verkürzen.According to a further aspect, the protective cover and the slider are designed in a mirrored manner on the winding plane. This design allows toroidal cores to be wound in both directions of rotation and can thus shorten the winding cycle time.

Im Sinne der Erfindung schließt der Begriff Ringkern auch Rohrkerne oder Kerne mit besonderer Öffnungsgeometrie ein und betrifft insbesondere solche Ringkerne mit geringer Materialfestigkeit oder Kerne mit verwinkelter Öffnungsgeometrie sowie Rohrkerne, die aufgrund ihrer geringen Materialfestigkeit nicht mit herkömmlichen Ringkern-Wickelvorrichtung bewickelt werden können, da die Bewicklung mit einem Draht zum Materialversagen des Ringkerns führen würde. Die hier beschriebenen Ausführungsformen eignen sich jedoch ebenfalls zum Bewickeln von sonstigen Ringkernen oder Kernen mit sonstiger Öffnung und auch solchen mit hoher Materialfestigkeit und erlauben ein einfaches und komfortables Bewickeln.In the context of the invention, the term toroidal core also includes tube cores or cores with a special opening geometry and relates in particular to those toroidal cores with low material strength or cores with angled opening geometry as well as tube cores which, due to their low material strength, cannot be wound with conventional toroidal core winding devices because the winding with a wire would lead to material failure of the toroidal core.
