The method includes winding the wire onto the toroidal core in a fixed winding plane, rotating the toroidal core during winding, the rotating being about an axis that is perpendicular to a plane of the ring shape of the magazine, and holding the toroidal core using a gripper that moves with the toroidal core during winding.

Description

Die Erfindung betrifft ein Verfahren zum Bewickeln eines Ringkerns, wobei der Ringkern um eine senkrecht zur Ringebene stehenden Achse gedreht wird.The invention relates to a method for winding a toroidal core, wherein the toroidal core is rotated about an axis perpendicular to the ring plane.

Aus den Druckschriften DE 12 01 488 B und JP 01 091409 sind Verfahren der eingangs genannten Art bekannt, bei denen der Ringkern mittels eines Drahtmagazins in einer ortsfesten Ebene bewickelt wird. In der Druckschrift DE 12 01 488 B wird ein Verfahren beschrieben, bei dem der Ringkern zwischen drei im Winkel von 120° versetzten Rollen gehalten und durch gleichmäßiges Drehen der Rollen in die entsprechende Wickelposition bewegt wird.From the pamphlets DE 12 01 488 B and JP 01 091409 Methods of the type mentioned are known in which the toroidal core is wound by means of a wire magazine in a stationary plane. In the publication DE 12 01 488 B a method is described in which the toroidal core is held between three offset at an angle of 120 ° rollers and moved by uniform rotation of the rollers in the corresponding winding position.

In der Druckschrift JP 04 017314 A wird ein weiteres Verfahren zum Bewickeln eines Ringskerns beschrieben.In the publication JP 04 017314 A Another method of winding a ring core is described.

Dieses Verfahren hat den Nachteil, daß die nach Beginn des Aufwickelvorgangs einsetzende Größenänderung des Ringkerns aufgrund der aufgebrachten Wicklungen eine exzentrische Lage des Kerns zum Drahtmagazin bewirkt. Dabei ist die sich ergebende Exzentrizität um so größer, je dicker der aufgewickelte Draht ist. Das Loch in der Mitte des Ringkerns muß aus diesem Grund wesentlich größer sein als der Querschnitt des verwendeten Drahtmagazins. Somit ist das bekannte Verfahren zum Bewickeln von Ringkernen mit einem sich ergebenden Restloch in der Größe des verwendeten Magazinquerschnitts nicht geeignet.This method has the disadvantage that the change in size of the toroidal core commencing after the start of the winding operation causes an eccentric position of the core to the wire magazine due to the applied windings. The resulting eccentricity is greater, the thicker the wound wire is. The hole in the center of the ring core must therefore be much larger than the cross section of the wire magazine used for this reason. Thus, the known method for winding ring cores with a resulting residual hole in the size of the magazine cross-section used is not suitable.

Zudem führt das bekannte Verfahren mit dem Rollenantrieb zu einem Taumeln des Ringkerns während des Bewickelns, wodurch ebenfalls das Loch in der Mitte des Ringkerns größer sein muß.In addition, the known method with the roller drive leads to a tumbling of the toroidal core during winding, whereby also the hole in the middle of the toroidal core must be larger.

Ziel der vorliegenden Erfindung ist es daher, ein Verfahren zum Bewickeln eines Ringkerns anzugeben, das die Bewicklung kleiner Ringkerne ermöglicht.The aim of the present invention is therefore to provide a method for winding a toroidal core, which allows the winding of small ring cores.

Dieses Ziel wird erfindungsgemäß durch ein Verfahren zum Bewickeln eines Ringkerns nach Patentanspruch 1 erreicht. Vorteilhafte Ausgestaltungen der Erfindung sind den weiteren Patentansprüchen zu entnehmen.This object is achieved by a method for winding a toroidal core according to claim 1. advantageous Embodiments of the invention can be found in the further claims.

Die Erfindung gibt ein Verfahren zum Bewickeln eines Ringkerns mit einem Draht an, wobei die Bewicklung des Ringkerns in einer ortsfesten Wickelebene erfolgt. Während des Bewikkelns wird der Ringkern von einem mit dem Ringkern mitlaufenden Greifer gehalten und um seine senkrecht zur Ringebene stehenden Achse gedreht.The invention provides a method for winding a toroidal core with a wire, wherein the winding of the toroidal core takes place in a stationary winding plane. During Bewikkelns the toroidal core is held by a follower with the toroidal gripper and rotated about its axis perpendicular to the plane of the ring axis.

Das erfindungsgemäße Verfahren hat den Vorteil, daß der Ringkern unabhängig von seiner Bewicklung immer fest von dem Greifer gehalten wird und dadurch Exzentrizitäten vermieden werden können. Die Bewicklung des Ringkerns kann beispielsweise mittels eines Drahtmagazins, das im wesentlichen auch die Form eines Rings hat, durchgeführt werden. Dabei kann der Greifer den Ringkern in oder gegen den Uhrzeigersinn um das Magazin herumführen.The method according to the invention has the advantage that the toroidal core is always held firmly by the gripper independently of its winding and thus eccentricities can be avoided. The winding of the toroidal core can be carried out, for example, by means of a wire magazine, which also essentially has the shape of a ring. The gripper can guide the toroid around or around the magazine clockwise or counterclockwise.

Die von dem Greifer auf dem Ringkern benutzte Fläche kann klein gehalten werden, und ist in einer vorteilhaften Weiterbildung der Erfindung nur so groß, wie es dem zur elektrischen Isolation erforderlichen Abstand zwischen zwei Wicklungen entspricht, so daß durch die vom Greifer eingenommenen Fläche keine Einschränkung der Bewicklung des Ringkerns resultiert.The area used by the gripper on the toroidal core can be kept small, and in an advantageous embodiment of the invention is only as large as it corresponds to the distance required for electrical insulation between two windings, so that by the gripper occupied area no restriction of Winding of the ring core results.

In einer weiteren vorteilhaften Ausführungsform der Erfindung bedeckt der Greifer weniger als 4% des Umfangs des Ringkerns. Dadurch kann dafür Sorge getragen werden, daß für die Bewicklung des Ringkerns mit Wicklungen keine Einschränkung besteht, da ohnehin zwischen den einzelnen Wicklungen aus Gründen der elektrischen Isolierung eines Mindestabstand eingehalten werden muß. Gegebenenfalls kann der Greifer an den Mindestabstand zwischen zwei Wicklungen angepaßt werden, so daß eine Einschränkung der Wicklungen durch den Greifer ausgeschlossen wird.In a further advantageous embodiment of the invention, the gripper covered less than 4% of the circumference of the toroidal core. As a result, care can be taken that there is no restriction for the winding of the toroidal core with windings, since a minimum distance must anyway be maintained between the individual windings for reasons of electrical insulation. Optionally, the gripper can be adapted to the minimum distance between two windings, so that a limitation of the windings is excluded by the gripper.

Es ist ferner vorteilhaft, wenn während des Bewickelns des Ringkerns in der Nähe der Wickelebene ein Gegenlager angeordnet ist, durch das der Ring gleiten kann und das die beim Wickeln auftretenden Zugkräfte des Drahtes aufnimmt. Das Gegenlager ist insbesondere erforderlich für Greiferstellungen, wo die Ebene, in der der Greifer liegt, senkrecht auf der Wickelebene steht. In diesem Fall sind die durch die Drahtzugkräfte erzeugten, am Greifer anliegenden auftretenden Momente am größten.It is also advantageous if during the winding of the toroidal core in the vicinity of the winding plane an abutment is arranged, through which the ring can slide and which absorbs the tensile forces of the wire occurring during winding. The anvil is particularly required for gripper positions where the plane in which the gripper is located, is perpendicular to the winding plane. In this case, the torques generated by the Drahtzugkräfte, applied to the gripper occurring moments are greatest.

Um den Kern über seinen vollen Umfang bewickeln zu können, ist es vorteilhaft, wenn das Gegenlager nur so lange im Eingriff mit dem Ringkern bleibt, bis sich der Greifer gegen Ende des Wickelprozesses zwangsläufig dem Gegenlager nähert. Zu diesem Zeitpunkt kann das Gegenlager ausschwenken und der Greifer noch eine weitere Drehbewegung des Ringkerns erzeugen. Dadurch kann der Kern nahezu ganz bewickelt werden. In dieser Greiferposition sind auch die durch die Zugkräfte erzeugten Biegemomente, die auf dem Greifer wirken, nicht mehr kritisch, da die Greiferebene nur noch einen sehr kleinen Winkel zur Wickelebene einschließt.In order to be able to wrap the core over its full circumference, it is advantageous if the counter bearing only remains in engagement with the ring core until the gripper inevitably approaches the counter bearing towards the end of the winding process. At this time, the anvil can swing out and the gripper still produce a further rotational movement of the toroidal core. As a result, the core can be almost completely wound. In this gripper position and the bending forces generated by the tensile forces acting on the gripper are no longer critical, since the gripper level includes only a very small angle to the winding plane.

Das Verfahren zum Bewickeln eines Ringkerns kann weiterhin verbessert werden, indem der Greifer durch einen präzisen Schrittmotor gesteuert wird. Dadurch wird eine exakte Steigungsvorgabe, das heißt, der notwendige Vorschub des Ringkerns in Relation zum Drahtdurchmesser auch für mehrlagige Drosseln ermöglicht.The method of winding a toroidal core can be further improved by controlling the gripper with a precise stepping motor. As a result, an exact pitch specification, that is, the necessary feed of the toroidal core in relation to the wire diameter also allows for multi-layer throttles.

Das erfindungsgemäße Verfahren hat weiterhin den Vorteil, daß auch extrem kleine Ringkerne mit einem Außendurchmesser < 4 mm, welche mit Hilfe der Rollenlagerung nicht mehr bewikkelt werden können, nun der Bewicklung mit automatischen Bewicklungsmaschinen zugänglich sind.The inventive method has the further advantage that even extremely small toroidal cores with an outer diameter <4 mm, which can not be bewikkelt using the roller bearing, now the winding with automatic Bewicklungsmaschinen are accessible.

Darüber hinaus ermöglicht es die Bewicklung von Ringkernen mit relativ kleinem Innenloch, wobei die Bewicklung mit dikken Drähten oder hoher Windungszahl erfolgen kann.In addition, it allows the winding of ring cores with a relatively small inner hole, the winding can be done with thick wires or high number of turns.

Der Kern kann bei einem sehr kleinen bzw. schmalen Greifer über einen Winkel von mindestens 350° bewickelt werden.The core can be wound with a very small or narrow gripper over an angle of at least 350 °.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels und den dazugehörigen Figuren näher erläutert.

Figur 1
zeigt beispielhaft eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens am Anfang des Bewicklungsvorgangs in einer schematischen Darstellung.
Figur 2
zeigt eine Vorrichtung nach Figur 1 etwa nach der Hälfte des Bewicklungsvorgangs.
Figur 3
zeigt eine Vorrichtung nach Figur 1 gegen Ende des Bewicklungsvorgangs.
Figur 4
zeigt den Schnitt durch eine Vorrichtung nach Figur 1, der das Gegenlager zeigt.

zeigt einen Schnitt durch eine Vorrichtung nach Figur 1, der den Greifer zeigt.
In the following the invention will be explained in more detail with reference to an embodiment and the associated figures.
FIG. 1
shows an example of an apparatus for performing the method according to the invention at the beginning of Bewicklungsvorgangs in a schematic representation.
FIG. 2
shows a device after FIG. 1 about halfway through the winding process.
FIG. 3
shows a device after FIG. 1 towards the end of the winding process.
FIG. 4
shows the section through a device FIG. 1 showing the counter bearing.
FIG. 5
shows a section through a device according to Figure 1, showing the gripper.

Figur 1 zeigt einen Ringkern 1 in Form eines Kreisringes, dessen Ober- und Unterseite jeweils durch eine ebene Fläche begrenzt ist. Der Ringkern 1 wird mittels eines Drahtmagazins 6, das in Figur 1 im Schnitt dargestellt ist, und das sich senkrecht zur Zeichenebene erstreckt, in der ortsfesten Wikkelebene 3 bewickelt. Der auf dem Drahtmagazin 6 aufgewickelte Draht 2 wird auf den Ringkern 1 aufgewickelt. Der Ringkern 1 wird von einem Greifer 4, der den Ringkern hält, bewegt. Der gekrümmte Pfeil zeigt die Drehrichtung des Greifers 4 an. Auf der dem Greifer 4 entgegengesetzten Seite des Drahtmagazins 6 ist ein Gegenlager 5 angeordnet, das die Biegemomente, die aus dem Drahtzugkräften resultieren, aufnimmt. FIG. 1 shows a ring core 1 in the form of a circular ring whose top and bottom is bounded in each case by a flat surface. The ring core 1 is by means of a wire magazine 6, the in FIG. 1 is shown in section, and which extends perpendicular to the plane, wound in the stationary Wikkelebene 3. The wound on the wire magazine 6 wire 2 is wound on the ring core 1. The toroidal core 1 is moved by a gripper 4 which holds the toroidal core. The curved arrow indicates the direction of rotation of the gripper 4. On the gripper 4 opposite side of the wire magazine 6, an abutment 5 is arranged, which absorbs the bending moments resulting from the Drahtzugkräften.

Figur 2 zeigt die Vorrichtung nach Figur 1, wobei etwa die Hälfte des Wickelvorgangs beendet ist. FIG. 2 shows the device after FIG. 1 , wherein about half of the winding process is completed.

Figur 3 zeigt die Vorrichtung nach Figur 1, kurz vor Beendigung des Wickelvorgangs. Um einen möglichst großen Bereich des Ringkerns 1 bewickeln zu können, wird das Gegenlager 5 gegen Ende des Wickelvorgangs durch eine mit dem Pfeil angezeigte Bewegung ausgerückt, so daß der Greifer 4 den Kern 1 im Wickelsinn weiterführen kann und sich nahe an die Wickelebene 3 annähern kann. Dabei übernimmt er die Stützfunktion des Gegenlagers 5. In diesem Zustand treten auch keine großen Biegemomente auf, da die Ebene des Greifers 4 mit der Wickelebene 3 nur einen sehr kleinen Winkel einschließt. FIG. 3 shows the device after FIG. 1 , just before the end of the winding process. In order to be able to wind the largest possible area of the toroidal core 1, the counter bearing 5 is disengaged towards the end of the winding process by a movement indicated by the arrow, so that the gripper 4 can continue the core 1 in the winding direction and can approach close to the winding plane 3 , He assumes the support function of the thrust bearing 5. In this state, no large bending moments occur because the plane of the gripper 4 with the winding plane 3 includes only a very small angle.

Figur 4 zeigt den von dem Gegenlager 5 gehaltenen Ringkern 1. Ferner sind verschiedene Positionen des aufgewickelten Drahtes 2 dargestellt. Die Zugkräfte F werden dabei jeweils in Drahtrichtung ausgeübt. Sie erzeugen ein Biegemoment M, welches durch den gekrümmten Doppelpfeil illustriert ist. FIG. 4 shows held by the anvil 5 ring core 1. Furthermore, various positions of the wound wire 2 are shown. The tensile forces F are in each case exercised in the wire direction. They generate a bending moment M, which is illustrated by the curved double arrow.

Der Ringkern 1 kann dabei in dem Gegenlager 5 mittels eines Kugellagers 7 gelagert sein. Es ist aber auch möglich, den Ringkern 1 mittels eines gleitfähigen Kunststoffs in dem Gegenlager 5 zu lagern.The ring core 1 can be stored in the counter bearing 5 by means of a ball bearing 7. But it is also possible to store the ring core 1 by means of a lubricious plastic in the anvil 5.

Figur 5 zeigt den vom Greifer 4 festgehaltenen Ringkern 1, wobei die Schnittebene in der Wickelebene liegt. Zusätzlich ist der Draht 2 schematisch in verschiedenen Momentaufnahmen während des Bewickelns dargestellt. Die Darstellung der Zugkräfte F und des Biegemoments M entspricht der Darstellung in Figur 4. Der Greifer 4 kann aus zwei Hälften bestehen, die durch Auseinanderdrücken in der mit dem Doppelpfeil gekennzeichneten Richtung vom Ringkern 1 entfernt werden können, wodurch der Ringkern 1 nach dem Bewicklungsvorgang entnommen werden kann. FIG. 5 shows the detained by the gripper 4 toroidal core 1, wherein the cutting plane is in the winding plane. In addition, the wire 2 is shown schematically in various snapshots during winding. The representation of the tensile forces F and the bending moment M corresponds to the illustration in FIG FIG. 4 , The gripper 4 may consist of two halves, which can be removed from the ring core 1 by pushing apart in the direction indicated by the double arrow, whereby the ring core 1 can be removed after the Bewicklungsvorgang.

Die Erfindung beschränkt sich nicht auf die dargestellten Ausführungsbeispiele, sondern wird in ihrer allgemeinsten Form durch Patentanspruch 1 definiert.The invention is not limited to the illustrated embodiments, but is defined in its most general form by claim 1.
