Abstract

A method and apparatus for winding ring cores, ring coils, ring core parts or ring coil parts, especially of ring core transformers or ring core measuring transformers, whereby the arrangement includes a winding material storage unit (33) which is moved alternately by means of two transfer mechanisms (20, 21) a distance about the ring core (5). Winding material 51 present on a supply roller (50) is thereby reeled off and wound on the ring core (5). The transfer mechanisms (20, 21) thereby move equally but in opposite directions between two transfer places (U 1, U 2) and are coupled respectively decoupled thereat with respective transfer mechanisms (20, respectively 21). The winding material storage unit (33) is thereby guided as structural unit during each winding through the ring core opening (7) of the ring core (5) respectively ring coil or the like.

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren und auf eine Vorrichtung zum Bewickeln von Ringkernen, Ringkernspulen, Ringkernteilen oder Ringspulenteilen gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a method and a device for winding toroidal cores, toroidal core coils, toroidal core parts or toroidal coil parts according to the preamble of claim 1.

Aus der DE-A-1 614 712 und der DD-A-149442 sind Verfahren und Vorrichtungen bekannt, bei denen ein Ringkern, beispielsweise der Eisenkern eines Ringkerntransformators, mittels eines als offener Ring ausgebildeten Wickelgutspeichers dadurch bewickelt wird, daß der Ring des Wickelgutspeichers den Ringkern umgibt und beim Drehen um seine eigene Achse das auf ihm gespeicherte Wickelgut auf den Ringkern aufwickelt. Dabei dreht sich der Ringkern relativ zum Wickelgutspeicher um seine Zentralachse, so daß das Wickelgut, hier der Draht mit bestimmter, evtl. veränderbarer Steigung, auf den Ringkern aufgewickelt wird.Methods and devices are known from DE-A-1 614 712 and DD-A-149442, in which a toroidal core, for example the iron core of a toroidal core transformer, is wound by means of a winding material storage device designed as an open ring in that the ring of the winding material storage device Surrounds the ring core and winds the winding material stored on it onto the ring core when rotating about its own axis. The ring core rotates relative to the winding material storage about its central axis, so that the winding material, here the wire with a certain, possibly variable pitch, is wound onto the ring core.

Der Wickelgutspeicher gemäß der DD-A-149 442 kann dabei relativ schmal gehalten werden, da das Wickelgut während des Wickelvorganges laufend ergänzt wird.The winding material storage according to DD-A-149 442 can be kept relatively narrow, since the winding material is continuously supplemented during the winding process.

Derartige Wickelgutspeicherringe sind jedoch nur dann einsetzbar, wenn die Länge des Ringkernes nicht sehr groß ist, d. h. wenn dessen Querschnitt wenigstens annähernd quadratisch ist oder wenn der Ringkerndurchmesser besonders groß ist. Maximal kann die Ringkernlänge jedoch höchstens annähernd dem Durchmesser des Speicherringes betragen und die lichte Weite des Ringkernes muß mindestens dem Radius des Speicherringes entsprechen. Somit kann mit einer derartigen Vorrichtung höchstens ein Ringkern bewickelt werden, dessen Länge etwa doppelt so groß ist wie seine lichte Weite.Such winding material storage rings can, however, only be used if the length of the toroidal core is not very long, ie. H. if its cross-section is at least approximately square or if the toroidal core diameter is particularly large. However, the maximum length of the toroidal core can at most be approximately the diameter of the storage ring and the clear width of the toroidal core must at least correspond to the radius of the storage ring. Thus, at most one toroid can be wound with such a device, the length of which is approximately twice as large as its clear width.

Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, ein Verfahren und eine dafür geeignete Vorrichtung zu schaffen, mit dem bzw. der auch Ringkerne, Ringspulen, Ringkernteile oder Ringspulenteile bewickelt werden können, deren Länge ein Vielfaches ihrer lichten Weite beträgt. Insbesondere soll die Erfindung auch zur Lösung der Aufgabe geeignet sein, Ringkerne oder Ringspulen mit kleiner lichter Weite bzw. kleinem Öffnungsquerschnitt zu bewickeln.The object of the present invention is to provide a method and a device suitable therefor with which toroidal cores, toroidal coils, toroidal core parts or toroidal coil parts can also be wound, the length of which is a multiple of their clear width. In particular, the invention should also be suitable for solving the task of winding toroidal cores or toroidal coils with a small internal width or a small opening cross section.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale der Ansprüche 1 und 10 gelöst.According to the invention, this object is achieved by the characterizing features of claims 1 and 10.

Bei dem erfindungsgemäßen Verfahren bzw. bei der erfindungsgemäßen Vorrichtung ist die Länge des zu bewickelnden Ringkernes, der zu bewickelnden Ringspule, bzw. der zu bewickelnden Ringkernteile oder Ringspulenteile nur noch durch die Länge der Übergabevorrichtung bzw. Übergabevorrichtungen begrenzt.In the method according to the invention or in the device according to the invention, the length of the toroidal core to be wound, the toroidal coil to be wound, or the toroidal core parts or toroidal coil parts to be wound is only limited by the length of the transfer device or transfer devices.

In Figur 1 ist an einem Ständer 1 ein Tragarm 2 vorgesehen, der eine insbesondere als Schlittenbett ausgebildete Auflagefläche 3 aufweist. An letzterer ist ein Tragtisch 4 insbesondere längs des Tragarmes 2 erstellbar und in bestimmten Einstellagen fixierbar angeordnet. Auf dem Tragtisch 4 ist ein beispielsweise als zu bewickelnder Spulen- oder Eisenkörper ausgebildeter Ringkern 5 aufgespannt oder in sonst geeigneter Weise befestigt. Der Tragtisch 4 ist mit einer Aussparung 6 versehen, deren Tiefe sich wenigstens annähernd über den Durchmesser der Ringöffnung 7, also über die lichte Weite eines Ringkerns 5 erstreckt und den Tragtisch 4 an einer Seite, hier an der linken Frontseite 8, durchtrennt.In FIG. 1, a support arm 2 is provided on a stand 1, which has a support surface 3, which is designed in particular as a slide bed. A support table 4 can be created on the latter, in particular along the support arm 2, and can be fixed in certain setting positions. On the support table 4, for example, a toroidal core 5 designed as a coil or iron body to be wound is clamped or fastened in any other suitable manner. The support table 4 is provided with a recess 6, the depth of which extends at least approximately over the diameter of the ring opening 7, that is to say over the clear width of an annular core 5, and cuts through the support table 4 on one side, here on the left front side 8.

An den Enden 9 des Tragarmes 2 sind Stützen 10, 11, insbesondere senkrecht zum Tragarm 2, angebracht. In oder an diesen Stützen 10, 11 ist je ein Tragpfosten 12, 13 in Achsrichtung der Stützen 10, 11, also senkrecht zum Tragarm 2, verschiebbar gelagert. Die Tragpfosten 12, 13 sind über je einen Stellantrieb 14, 15 verstellbar. Gegebenenfalls können die Tragpfosten 12, 13 über einen Verbindungssteg 16 miteinander starr gekuppelt sein. Die Tragpfosten 12, 13 können daher auch gemeinsam, gegebenenfalls mittels eines vorzugsweise mittig am Verbindungssteg 16 angreifenden Stellantriebs 17 senkrecht zum Tragarm 2, verstellt werden.Supports 10, 11, in particular perpendicular to the support arm 2, are attached to the ends 9 of the support arm 2. In or on these supports 10, 11, a support post 12, 13 is slidably mounted in the axial direction of the supports 10, 11, that is perpendicular to the support arm 2. The support posts 12, 13 are each adjustable via an actuator 14, 15. Optionally, the support posts 12, 13 can be rigidly coupled to one another via a connecting web 16. The support posts 12, 13 can therefore also be adjusted jointly, if necessary by means of an actuator 17, which preferably engages in the center of the connecting web 16, perpendicular to the support arm 2.

An den freien Enden 18, 19 der Tragpfosten 12, 13 ist je eine Übergabevorrichtung 20, 21 senkrecht zu den Tragpfosten 12, 13, also parallel zu der Auflagefläche 3 am Tragarm 2, verschiebbar gelagert. Jede Übergabevorrichtung 20, 21 ist über einen eigenen Stellantrieb 22, 23 verstellbar. Die Übergabevorrichtungen 20, 21 bestehen hier aus je einem mit dem zugeordneten Stellantrieb 22 bzw. 23 gekoppelten Stab 24 bzw. 25, an deren freien Enden 26 bzw. 27 je eine Übernahmekupplung 28 bzw. 29 angebracht ist. Letztere ist mit einem Gegenkupplungsteil 30 bzw. 31 eines Trägers 32 einer Wickelgutspeichereinheit 33 kuppelbar.At the free ends 18, 19 of the support posts 12, 13, a transfer device 20, 21 is slidably mounted perpendicular to the support posts 12, 13, that is, parallel to the bearing surface 3 on the support arm 2. Each transfer device 20, 21 is adjustable via its own actuator 22, 23. The transfer devices 20, 21 here each consist of a rod 24 or 25 coupled to the associated actuator 22 or 23, on the free ends 26 or 27 of which a take-up coupling 28 or 29 is attached. The latter can be coupled to a mating coupling part 30 or 31 of a carrier 32 of a winding material storage unit 33.

Zur besseren Lagefixierung, insbesondere um ein Kippen des Trägers 32 auf einer Übernahmekupplung 28 bzw. 29 zu verhindern, besteht der Träger 32 aus einem in der Zeichenebene senkrecht angeordneten und daher hier nicht sichtbaren Tragkörper 34 (Figur 2), einer an diesem befestigten, senkrecht zum Tragkörper 34 abstehenden Drehachse 35 und einem am freien Ende derselben starr befestigten, zweiten Tragkörper 36. Im ersteren Tragkörper 34 sind bezüglich der Drehachse 35 an diametral gegenüberliegenden Stellen 37, 38 die Gegenkupplungsteile 30 bzw. 31 vorgesehen. Im zweiten Tragkörper 36 sind entsprechend angebrachte Lagefixierelemente 39 in Form von Aussparungen und/oder Erhöhungen, beim Ausführungsbeispiel in Form von Bohrungen, angebracht.To better fix the position, in particular to prevent the carrier 32 from tilting on a take-over coupling 28 or 29, the carrier 32 consists of a support body 34 (FIG. 2), which is arranged vertically in the plane of the drawing and is therefore not visible here, one vertically attached to the latter to the support body 34 protruding axis of rotation 35 and one at the free end the same rigidly fastened second support body 36. In the former support body 34, the counter-coupling parts 30 and 31 are provided at diametrically opposite points 37, 38 with respect to the axis of rotation 35. Correspondingly attached position fixing elements 39 in the form of recesses and / or elevations, in the embodiment in the form of bores, are mounted in the second support body 36.

Wie in Figur 2 dargestellt, besteht die Kupplung zwischen den Stäben 24 bzw. 25 und dem Träger 32 aus Bajonettverschlüssen, wobei im Stabende seitlich abstehende Stifte 40 und im Tragkörper 34 Bohrungen 41 und die Bajonettwinkelschlitze 42 vorgesehen sind. Die Kupplung erfolgt durch Einstecken des Stabendes in die Bohrung 41 und anschließendes Verdrehen des Stabes 24 bzw. 25 in Richtung des Pfeiles 43.As shown in FIG. 2, the coupling between the rods 24 and 25 and the carrier 32 consists of bayonet locks, pins 40 projecting laterally in the rod end and bores 41 and the bayonet angle slots 42 being provided in the support body 34. The coupling is carried out by inserting the rod end into the bore 41 and then turning the rod 24 or 25 in the direction of arrow 43.

Die Lagefixierung des Trägers 32 der Wickelgutspeichereinheit 33 erfolgt durch Einsetzen der Enden 44 von Fixierstäben 45, 46 in Bohrungen 36 des zweiten Tragkörpers 36. Der Fixierstab 45 bzw. 46 ist beispielsweise über einen mit dem Stellantrieb 22 bzw. 23 und dem Tragpfosten 12 bzw. 13 verbundenen Führungskopf 47 bzw. 48 mit dem Stab 24 bzw. 25 starr gekuppelt.The position of the carrier 32 of the winding material storage unit 33 is fixed by inserting the ends 44 of fixing rods 45, 46 into bores 36 of the second support body 36. The fixing rod 45 or 46 is, for example, connected to the actuator 22 or 23 and the support post 12 or 13 connected guide head 47 or 48 rigidly coupled to the rod 24 or 25.

Auf der Drehachse 35 ist ein Führungshebel 49 drehbar gelagert. Dieser dient zur Halterung einer an ihrem einen Ende starr oder drehbar gelagerten Vorratsrolle 50 für ein Wickelgut 51. Andererseits dient der Führungshebel 49 auch zur Halterung einer an ihm drehbar gelagerten Andrückrolle 52, wenn diese nicht unmittelbar auf der Drehachse 36 gelagert ist, wie dies beim Ausführungsbeispiel der Fall ist. Gegebenenfalls kann die Andrückrolle 52 auch auf dem über die Drehachse 35 hinaus verlängerten Teil des Führungshebels 49 angeordnet sein. Die Vorratsrolle 50 und die Andrückrolle 52 sind hier so angeordnet, daß erstere weiter von der Drehachse 35 entfernt ist als die Andrückrolle 52. Wird anstelle der beiden Rollen 50, 52 nur eine Vorratsrolle 50 verwendet, so ist diese zugleich die Andrückrolle und sie ist dann auf der Drehachse 35 gelagert.A guide lever 49 is rotatably mounted on the axis of rotation 35. This is used to hold a supply roll 50, which is rigidly or rotatably mounted at one end, for a winding material 51. On the other hand, the guide lever 49 also serves to hold a pressure roll 52 rotatably mounted on it, if this is not mounted directly on the axis of rotation 36, as in Embodiment is the case. If necessary, the pressure roller 52 can also be arranged on the part of the guide lever 49 which is extended beyond the axis of rotation 35. The supply roller 50 and the pressure roller 52 are arranged here in such a way that the former is further away from the axis of rotation 35 than the pressure roller 52. If only one supply roller 50 is used instead of the two rollers 50, 52, this is also the pressure roller and it is then mounted on the axis of rotation 35.

Die Vorratsrolle 50 kann gemäß Figur 3 zweiteilig ausgeführt sein, wobei das eine Teil 501 am Führungshebel 49 starr oder drehbar gehaltert ist und das andere Teil 502 in ersteres einschraubbar ist oder beide Teile 501, 502 in sonst geeigneter Weise, beispielsweise über ein federndes Spannglied, miteinander verbindbar sind. Hierdurch kann auf die Vorratsrolle 50 leicht und schnell eine mit Wickelgut 50 bewickelte Hülse 53 aufgeschoben und lagerichtig gehaltert werden.The supply roll 50 can be designed in two parts according to FIG. 3, one part 501 being held rigidly or rotatably on the guide lever 49 and the other part 502 being screwable in the former, or both parts 501, 502 in an otherwise suitable manner, for example via a resilient tensioning member, are interconnectable. As a result, a sleeve 53 wound with material to be wound 50 can be easily and quickly pushed onto the supply roll 50 and held in the correct position.

Auf einer Flanschseite ist neben oder auf dem einen Rollenflansch 54 der Vorratsrolle 50 eine Auflagescheibe 55 vorgesehen. Diese kann auch vom Rollenflansch 54 selbst gebildet sein. Vorzugsweise besteht der Rollenflansch 54 bzw. die Auflagescheibe 55 oder zumindest deren Rand 56 aus einem Material, das einen geringen Reibungskoeffizienten besitzt, wie beispielsweise Messing, Polyamid, Teflon oder dgl. Auch ist die Auflagescheibe 55 drehbar angebracht, so daß beim Anliegen am Ringkern 5 während des Wickelvorgangs keine große Reibung entsteht.A washer 55 is provided on a flange side next to or on the one roller flange 54 of the supply roller 50. This can also be formed by the roller flange 54 itself. Preferably, the roller flange 54 or the support disk 55 or at least its edge 56 is made of a material that has a low coefficient of friction, such as brass, polyamide, Teflon or the like. Also, the support disk 55 is rotatably mounted so that when it is in contact with the toroidal core 5 there is no great friction during the winding process.

Das nachfolgend beschriebene erfindungsgemäße Wickelverfahren wird mit der vorgenannten Vorrichtung wie folgt durchgeführt :The winding method according to the invention described below is carried out with the aforementioned device as follows:

In Figur 4 ist die Vorrichtung im Augenblick der Übergabe der Wickelgutspeichereinheit 33 von der unteren Übergabevorrichtung 21 auf die obere Übergabevorrichtung 20 dargestellt. Zuvor ist die untere Übergabevorrichtung 21 nach oben und die obere Übergabevorrichtung 20 nach unten bewegt worden, wobei die Wickelgutspeichereinheit 33 mit der unteren Übergabevorrichtung 21 gekuppelt ist. Beide Übergabevorrichtungen 20, 21 befinden sich daher an einer ersten Übergabestelle Ü 1. Nach dem Einsetzen der Übernahmekupplung 28 in die Gegenkupplung 20 des Tragkörpers 34 und bei einer Bajonettkupplung nach dem Drehen des Stabes 24 ist die Wickelgutspeichereinheit 33 mit der Übergabevorrichtung 20 gekuppelt. Zugleich oder anschließend wird die untere Übergabevorrichtung 21 durch Drehen des Stabes 25 in Öffnungsrichtung vom Tragkörper 34 abgekoppelt.FIG. 4 shows the device at the moment of transfer of the winding material storage unit 33 from the lower transfer device 21 to the upper transfer device 20. The lower transfer device 21 has previously been moved upward and the upper transfer device 20 has been moved downward, the winding material storage unit 33 being coupled to the lower transfer device 21. Both transfer devices 20, 21 are therefore located at a first transfer point U 1. After inserting the take-over coupling 28 into the counter-coupling 20 of the support body 34 and in the case of a bayonet coupling after rotating the rod 24, the winding material storage unit 33 is coupled to the transfer device 20. At the same time or subsequently, the lower transfer device 21 is decoupled from the support body 34 by rotating the rod 25 in the opening direction.

Hierauf wird die obere Übergabevorrichtung 20 nach oben und die untere Übergabevorrichtung 21 nach unten bewegt. Die Stäbe 24, 25 sind durch die Stellantriebe 14, 15 bzw. durch den Stellantrieb 17 so weit nach rechts bewegt, daß die Andrückrolle 52 an der Innenwand 57 des Ringkernes 5, der Ringspule oder dgl. unter zumindest geringem Druck anliegt. Beim Nachobenbewegen wird daher die Andrückrolle 52 im Uhrzeigersinn gedreht. Dabei wird von der in Bewegungsrichtung vor der Andrückrolle 52 befindlichen Vorratsrolle 50 das Wickelgut 51 abgezogen und an die Innenwand 57 angedrückt, beispielsweise bei Verwendung eines einseitig selbstklebenden Bandes dort angeklebt.The upper transfer device 20 is then moved upward and the lower transfer device 21 is moved downward. The rods 24, 25 are moved so far to the right by the actuators 14, 15 or by the actuator 17 that the pressure roller 52 bears against the inner wall 57 of the toroidal core 5, the toroidal coil or the like under at least slight pressure. When moving upward, the pressure roller 52 is therefore rotated clockwise. In this case, the winding material 51 is pulled off the supply roll 50 located in front of the pressure roller 52 in the direction of movement and pressed onto the inner wall 57, for example when a self-adhesive tape is used, glued there.

Das Wickelgut 51 ist so aufgelegt, daß es von der der Innenwand 57 angewandten Seite abgezogen wird. Insbesondere bei Verwendung eines einseitig selbstklebenden Bandes, dessen Klebeseite auf der Vorratsrolle 50 nach innen weist. wird dadurch auf den Führungshebel 49 ein im Uhrzeigersinn wirkendes Moment erzeugt. Hierdurch wird die Vorratsrolle 50 mit ihrem Flanschrand bzw. die Auflagescheibe 55 mit ihrem Rand 56 leicht gegen die Innenwand 57 gedrückt. Durch diese Maßnahmen wird außerdem ein kontinuierliches Abwickeln des Wickelgutes 51 von der Wickelrolle erreicht. Gleichzeitig gleitet die Vorratsrolle 50 bzw. die Auflagescheibe 55 an der Innenwand 57 entlang, wobei die Vorratsrolle 50 entgegen dem Uhrzeigersinn gedreht wird. Bei einer drehbar angebrachten Andrückrolle 55 rollt diese mit ihrem Rand 56 auf der Innenwand 57 des Ringkernes 5 ab.The winding material 51 is placed in such a way that it is pulled off from the side applied to the inner wall 57. In particular when using a self-adhesive tape on one side, the adhesive side of which on the supply roll 50 points inwards. a clockwise moment is thereby generated on the guide lever 49. As a result, the supply roll 50 with its flange edge or the support disk 55 with its edge 56 is pressed slightly against the inner wall 57. These measures also achieve continuous unwinding of the winding material 51 from the winding roll. At the same time, the supply roll 50 or the support disk 55 slides along the inner wall 57, the supply roll 50 being rotated counterclockwise. In the case of a rotatably attached pressure roller 55, its edge 56 rolls on the inner wall 57 of the ring core 5.

Ist nun, wie die Figur 5 zeigt, die obere Übergabevorrichtung 20 an der oberen Innenkante 58 des Ringkernes 5 angelangt, dann wird die Vorratsrolle 50 infolge des vorstehend erwähnten Drehmoments um diese Innenkante 57 herum zur oberen Stirnfläche 59 des Ringkernes 5 gerollt und anschließend wird auch die Andrückrolle 52 automatisch gerollt, indem die obere und vorzugsweise zugleich auch die untere Übergabevorrichtung 20 bzw. 21 nach rechts bewegt werden und die Bewegung der Übergabevorrichtung 20 nach oben und die der Übergabevorrichtung 21 nach unten gestoppt wird.If, as shown in FIG. 5, the upper transfer device 20 has reached the upper inner edge 58 of the toroidal core 5, the supply roll 50 is rolled around this inner edge 57 to the upper end face 59 of the toroidal core 5 as a result of the aforementioned torque and then also the pressure roller 52 automatically rolled by the top and front preferably the lower transfer device 20 or 21 are also moved to the right and the movement of the transfer device 20 upwards and that of the transfer device 21 downward is stopped.

Beim Weiterbewegen der beiden Übergabevorrichtungen 20, 21 nach rechts wiederholt sich der Umlenkvorgang an der oberen Außenkante 60 des Ringkernes 5, wie in Figur 6 dargestellt.When the two transfer devices 20, 21 are moved further to the right, the deflection process is repeated on the upper outer edge 60 of the toroidal core 5, as shown in FIG.

Anschließend wird die obere Übergabevorrichtung 20 nach unten und die untere Übergabevorrichtung 21 nach oben bewegt und die seitliche Bewegung nach rechts gestoppt. Schließlich erreichen beide Übergabevorrichtungen 20, 21 eine in Figur 7 gezeigte zweite Übergabestelle Ü 2, an der die untere Übergabevorrichtung 21 mit dem Tragkörper 34 koppelt und die obere Übergabevorrichtung 20 entkoppelt. Hierauf werden beide Übergabevorrichtungen 20, 21 voneinander entfernt, indem die untere nach unten und die obere nach oben bewegt wird. Die Umfahrung der unteren Außenkante 61, der unteren Stirnfläche 62 und der unteren Innenkante 63 erfolgt entsprechend wie an der oberen Außenkante 60 bzw. an der oberen Stirnfläche 59, nur daß die beiden Übergabevorrichtungen 20, 21 jetzt dabei nach links bewegt werden.The upper transfer device 20 is then moved downward and the lower transfer device 21 is moved upward, and the lateral movement to the right is stopped. Finally, both transfer devices 20, 21 reach a second transfer point U 2 shown in FIG. 7, at which the lower transfer device 21 couples to the support body 34 and the upper transfer device 20 decouples. The two transfer devices 20, 21 are then removed from one another by moving the lower one downward and the upper one upward. The bypass of the lower outer edge 61, the lower end face 62 and the lower inner edge 63 is carried out in the same way as on the upper outer edge 60 and on the upper end face 59, except that the two transfer devices 20, 21 are now moved to the left.

Schließlich wird wieder die erste Übergabestelle Ü 1 erreicht, sodaß eine volle Windung des Wickelgutes 51 auf den Ringkern 5 aufgebracht ist.Finally, the first transfer point U 1 is reached again, so that a full turn of the winding material 51 is applied to the toroidal core 5.

Wie leicht einzusehen, können auf diese Weise auch sehr lange Spulen bzw. Ringkerne bewickelt werden, da diese nur von einer geeigneten Übergabevorrichtung, beim Ausführungsbeispiel von der Einstecklänge der Stäbe 24 bzw. 25 abhängt.As can be easily seen, very long coils or toroidal cores can also be wound in this way, since this only depends on a suitable transfer device, in the exemplary embodiment on the insertion length of the rods 24 or 25.

Beim Wickelvorgang sind die Übergabevorrichtungen 20, 21 immer im Abstand vom Ringkern 5 so geführt, daß immer ein leichter Andruck der Wickelgutspeichereinheit 33 an den Ringkern 5 möglich ist.During the winding process, the transfer devices 20, 21 are always guided at a distance from the toroidal core 5 so that a slight pressure of the winding material storage unit 33 against the toroidal core 5 is always possible.

Um den Ringkern 5 über seine ganze Länge bewickeln zu können, ist dieser auf dem Tragtisch 4 von Hand drehbar oder durch eine geeignete Einrichtung um seine Zentralachse 64 drehbar montiert. Die Drehung kann dabei so erfolgen, daß beispielsweise ein Wickeldraht an der Innenwand 57 abstandslos oder eng benachbart gewickelt wird oder daß dabei ein Isolier- oder ein Wickelband so aufgebracht wird, daß es an der Außenwand 65 überlappend oder nicht überlappend gewickelt wird.In order to be able to wind the toroidal core 5 over its entire length, it can be rotated by hand on the support table 4 or can be rotated about its central axis 64 by a suitable device. The rotation can take place in such a way that, for example, a winding wire is wound on the inner wall 57 without spacing or closely adjacent, or that an insulating tape or a winding tape is applied in such a way that it is wound overlapping or not overlapping on the outer wall 65.

Um eine möglichst schnelle Bewicklung vornehmen zu können, werden die Übergabevorrichtungen 20, 21 so durch die ihnen zugeordneten Stellantriebe 14, 22 bzw. 15, 23 bewegt, daß sie ihre vorgegebenen Wegstrecken, beispielsweise a, b, c, und a', b', c' in gleichen Zeiten durchlaufen. Vorteilhaft sind daher die zurückzulegenden Wegstrecken gleich lang und insbesondere je Bewegungsrichtung gleich lang, also bezüglich einer Mittellinie symmetrisch. Vorzugsweise sind die Übergabestellen daher im Bereich der Mittelinien, also beispielsweise jeweils in der Mitte der Länge des Ringkernes 5 vorgesehen. Im Ausführungsbeispiel ist dies dadurch erreicht, daß die erste Übergabestelle Ü 1 wenigstens annähernd in der Mitte innerhalb und die zweite Übergabestelle Ü 2 wenigstens annähernd in der Mitte außerhalb des Ringkernes 5 vorgesehen ist.In order to be able to carry out the winding as quickly as possible, the transfer devices 20, 21 are moved by the actuators 14, 22 or 15, 23 assigned to them in such a way that they move their predetermined distances, for example a, b, c, and a ', b' , c 'run through at the same times. The distances to be covered are therefore advantageously of the same length and in particular of the same length in each direction of movement, that is to say symmetrical with respect to a center line. The transfer points are therefore preferably provided in the region of the center lines, that is to say for example in the middle of the length of the toroidal core 5. In the exemplary embodiment, this is achieved in that the first transfer point U 1 is provided at least approximately in the middle within the ring core 5 and the second transfer point U 2 is at least approximately in the middle.

Durch die insbesondere stabförmige Ausbildung des die Übergabekupplung aufweisenden Teils der Übergabevorrichtungen 20, 21 und die mögliche schmale Bauweise der Wickelgutspeichereinheit können noch Ringkerne 5 mit relativ kleinem Durchmesser der Ringöffnung 7 bewickelt werden.Due to the particular rod-shaped design of the part of the transfer devices 20, 21 having the transfer coupling and the possible narrow construction of the winding material storage unit, toroidal cores 5 with a relatively small diameter of the ring opening 7 can still be wound.

Prinzipiell ist es auch möglich, mehr als zwei Übergabevorrichtungen vorzusehen, beispielsweise je eine für innen und außen und je eine für die obere und die untere Stirnfläche. Diese Anordnung kann insbesondere bei sehr großen Ringkernen vorteilhaft sein.In principle, it is also possible to provide more than two transfer devices, for example one for the inside and one for the outside and one for the upper and the lower end face. This arrangement can be particularly advantageous for very large toroidal cores.

Auch besteht die Möglichkeit, anstatt des Antriebes der Übergabevorrichtungen 20, 21 bzw. der Übergabekupplungen 28, 29 in zwei, insbesondere senkrecht zueinander stehenden Koordinaten, eine Mehrkoordinatensteuerung vorzusehen.It is also possible to provide a multi-coordinate control instead of driving the transfer devices 20, 21 or the transfer clutches 28, 29 in two, in particular mutually perpendicular, coordinates.

Als Stellantriebe 14, 15 bzw. 17 eignen sich hydraulische, elektrische, pneumatische oder gemischte Antriebsservos. Besonders vorteilhaft sind pneumatische Antriebe, da infolge der federnden Eigenschaften derselben das sanfte und trotzdem je nach Wunsch kräftige Anliegen der Andruckrolle 52 und/oder der Vorratsrolle 50 und/oder der Auflagescheibe 55 am Ringkern 5 leicht steuerbar ist.Hydraulic, electrical, pneumatic or mixed drive servos are suitable as actuators 14, 15 or 17. Pneumatic drives are particularly advantageous since, due to their resilient properties, the pressure roller 52 and / or the supply roller 50 and / or the support disc 55 on the toroidal core 5 can be easily and gently pressed as desired.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind bei Anwendung von Bajonettkupplungen die beiden am Tragkörper 34 bezüglich der Drehachse 35 einander diametral gegenüberliegenden Bajonettwinkelschlitze 42 zueinander gegenläufig vorgesehen, so daß jeder Stab 24 durch eine Rechts- oder durch eine Linksdrehung gekuppelt werden kann. Beide Bajonettverschlüsse sind also in diesem Fall links- oder rechtsgängig angebracht. Anstelle der Bajonettverschlüsse können auch Klemmkupplungen, beispielsweise nach Art von Spannzangen oder Spannpratzen, vorgesehen sein.According to an advantageous embodiment of the invention, when using bayonet couplings, the two bayonet angle slots 42 diametrically opposite one another on the support body 34 with respect to the axis of rotation 35 are provided in opposite directions, so that each rod 24 can be coupled by a right or a left turn. In this case, both bayonet locks are attached to the left or right. Instead of the bayonet locks, clamping couplings, for example in the manner of collets or clamping claws, can also be provided.

Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung eignen sich für jede Art von Bewicklung, Isolierung, Bandagierung oder dgl. von Ringkernen, Ringspulen, Ringkernteilen oder Ringspulenteilen.The method according to the invention and the device according to the invention are suitable for any type of winding, insulation, bandaging or the like of toroidal cores, toroidal coils, toroidal core parts or toroidal coil parts.

Unter Ringkernen oder Ringspulen werden hier vollkommen geschlossene oder durch Luftspalte überbrückte Kerne oder Spulen beliebiger geometrischer Anordnungen verstanden. Neben kreisringförmigen Kernen und Spulen können auch solche mit ovaler oder polyederförmiger Ausgestaltung bewickelt, isoliert oder bandagiert werden.Ring cores or ring coils are understood here to mean completely closed cores or coils of any geometric arrangement or bridged by air gaps. In addition to annular cores and coils, those with an oval or polyhedral configuration can also be wound, insulated or bandaged.
