An improved toroidal core attaching device for a winding device for toroidal coils including a receptacle sleeve held on a pivotable arm to receive the toroidal core, the core and receptacle being pivotable on the arm into the orbit of an annular wire magazine. The receptacle sleeve is open in a region of its generated surface which is directed to the center of the magazine in the winding position and the receptacle sleeve and toroidal core form a clamp therebetween for an end of the wire. The open region of the receptacle sleeve forms an access opening for the clamping area.

Description

Die Erfindung betrifft eine Ringkernspulen-Wickelvorrichtung mit einer Ringkern-Halterung, einem durch die Ringkern-Öffnung geführten, gegebenenfalls in einem Bereich seiner Länge unterbrochenen ringförmigen Magazin zur Drahtführung und Magazinierung, wobei der Ringkern und das Magazin um ihre vorzugsweise senkrecht zueinander ausgerichteten rotationssymmetrischen Achsen drehbar sind und mit einer Drahtzuführung zum Magazin.The invention relates to a toroidal coil winding device with a toroidal core holder, an annular magazine for wire guidance and magazation, which is guided through the toroidal core opening and possibly interrupted in a region of its length, the toroidal core and the magazine being rotatable about their rotationally symmetrical axes, which are preferably oriented perpendicular to one another and with a wire feed to the magazine.

Ringkernspulen-Wickelvorrichtungen dieser Art sind durch die US-PS 4 079 895 bekannt. Deren geschlossenes Magazin besitzt einen zum Austausch der Ringkerne aufklappbaren, während des Wickelns geschlossenen Teil. Das Magazin ist zudem so ausgebildet, daß bereits während des Bewickelns des Ringkerns das Magazinieren des Wickeldrahtes erfolgt. Der Drahtanfang wird von Hand am Ringkern fixiert und während des gesamten Wickelvorgangs von Hand geführt. Auch das Einfädeln des Drahtanfangs in das Magazin gestaltet sich sehr umständlich, da der Draht zwischen Bremsrollen, die den erforderlichen Wickelzug beim Wickel bewirken, eingefädelt werden muß.Toroidal core winding devices of this type are known from US Pat. No. 4,079,895. Their closed magazine has a part that can be opened for exchanging the ring cores and is closed during winding. The magazine is also designed so that the winding wire is already being magazineed while the ring core is being wound. The beginning of the wire is fixed to the toroid by hand and guided by hand during the entire winding process. The threading of the beginning of the wire into the magazine is also very cumbersome, since the wire must be threaded between brake rollers, which bring about the required winding tension during winding.

Eine Ringkernspulen-Wickelvorrichtung mit geschlossenem Magazin, das im übrigen nur eine Vorratsmagazinierung, also keine Magazinierung während des Wickelns zuläßt, ist durch die US-PS 3 982 705 bekannt. Der Drahtanfang wird dabei gleichfalls von Hand am Ringkern befestigt und von Hand während des gesamten Wickelvorganges geführt.A toroidal core winding device with a closed magazine, which, moreover, only permits magazine storage, that is to say no magazine during winding, is known from US Pat. No. 3,982,705. The wire start is also attached to the toroid by hand and guided by hand during the entire winding process.

Die DE-OS 2 307 014 beschreibt eine Wickelvorrichtung für Ablenkspulen mit in einem Bereich seiner Länge unterbrochenen und drehbar gelagerten Drahtvorratsmagazin und mit einem gleichfalls in einem Bereich seiner Länge unterbrochenen, sich drehenden Spulenwickelläufer, dem vom Drahtvorratsmagazin der Draht angeliefert wird. Auch bei dieser Wickelvorrichtung wird der Drahtanfang von Hand am Spulenwickelläufer fixiert und während des Wickelvorganges von Hand geführt.DE-OS 2 307 014 describes a winding device for deflection coils with a wire storage magazine which is interrupted and rotatably supported in a region of its length and with a rotating coil winder which is likewise interrupted in an area of its length and to which the wire is supplied by the wire storage magazine. With this winding device too, the beginning of the wire is fixed by hand to the bobbin winder and guided by hand during the winding process.

Die DE-PS 2 820 674 behandelt schließlich eine Wickelvorrichtung für Ringkernspulen mit einer Ringkern-Halterung, einem durch die Ringkern-Öffnung geführten, zur Drahtführung und Magazinierung mit drehbar gelagerten Gleitrollen ausgerüsteten, in einem Bereich seiner Länge unterbrochenen ringförmigen Magazin, wobei der Ringkern und das Magazin um ihre vorzugsweise senkrecht zueinander ausgerichteten rotationssymmetrischen Achsen drehbar sind, und mit einer Drahtzuführung, die derart ausgebildet ist, daß der Drahtanfang zwischen zwei Gleitrollen zu einem vom Magazin getrennten Fixierelement zum Fixieren des Drahtanfangs geführt wird, das auch vom Ringkern getrennt angeordnet ist und das den Drahtanfang im Verlauf des Wickelns wieder freigibt.DE-PS 2 820 674 finally deals with a winding device for toroidal coils with a toroidal holder, a guided through the toroidal opening, equipped for wire guidance and magazine with rotatably mounted sliding rollers, interrupted in an area of its length, annular magazine, the toroidal core and the magazine can be rotated about its preferably perpendicularly aligned rotationally symmetrical axes, and with a wire feed which is designed such that the wire start between two guide rollers is guided to a fixing element separate from the magazine for fixing the wire start, which is also arranged separately from the toroid and that releases the beginning of the wire in the course of winding.

Bei dieser Wickelvorrichtung erfolgt keine Fixierung des Drahtanfangs am Ringkern. Es ist jedoch darauf zu achten, daß der Drahtanfang nach erfolgter Freigabe durch das Fixierelement vom Innenloch des Ringkernes freigehalten wird; anderenfalls behindert das Drahtende die einwandfreie Führung des Wickelmagazins durch das Ringkern-Loch.With this winding device, the wire start is not fixed to the ring core. However, it must be ensured that the start of the wire is kept clear of the inner hole of the toroid after the release by the fixing element; otherwise the end of the wire prevents the winding magazine from being properly guided through the ring core hole.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Ringkernspulen-Wickelvorrichtung der eingangs genannten Art so zu verbessern, daß möglichst bereits auf eine Fixierung des Wickeldrahtanfanges von Hand zumindest jedoch auf die bei einzelnen Wickelvorrichtungen während des gesamten Wickelvorganges erforderliche manuelle Führung des Wickeldrahtanfanges verzichtet und die Fixierung und Führung weitgehend automatisch erfolgen kann.The present invention has for its object to improve a toroidal winding device of the type mentioned in such a way that, if possible, a fixation of the winding wire start by hand at least, however, the manual guidance of the winding wire beginning required for individual winding devices during the entire winding process is dispensed with and the fixing and leadership can be done largely automatically.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Ringkern-Halterung eine Aufnahmehülse für die Ringkerne aufweist, die in die Umlaufbahn des Magazins schwenkbar und in ihrem in Wickelstellung zur Magazinmitte gerichteten Bereich ihrer Mantelfläche offen ist.To achieve this object, the invention provides that the toroidal holder has a receiving sleeve for the toroidal cores, which can be pivoted into the orbit of the magazine and is open in its area of its lateral surface directed towards the center of the magazine in the winding position.

Zum Wickelbeginn wird gegebenenfalls selbsttätig der zu bewickelnde Ringkern auf diese Aufnahmehülse aufgesteckt und anschließend die Aufnahmehülse samt Ringkern in die Umlaufbahn des Magazins geschwenkt.At the start of the winding, the toroid to be wound is possibly automatically placed on this receiving sleeve and then the receiving sleeve together with the toroid is pivoted into the orbit of the magazine.

Bei Wickelvorrichtungen mit am Ringkern fixiertem Drahtanfang muß dieser nur kurzzeitig von Hand vom Ringkernloch ferngehalten werden, bis, bedingt durch die Drehung des Ringkerns beim Wickeln, der Drahtanfang sich zwischen der Aufnahmehülse und dem Ringkern befindet.In the case of winding devices with the start of the wire fixed to the ring core, this need only be kept briefly away from the ring core hole by hand until, due to the rotation of the ring core during winding, the wire start is between the receiving sleeve and the ring core.

Bei Einsatz dieser Ringkern-Halterung in einer durch die DE-PS 2 820 674 bekannten Ringkernspulen-Wickelvorrichtung entfällt auch diese manuelle Sicherung des Drahtanfangs. Bei dieser bevorzugten Wickelvorrichtung genügt es, wenn das vom Ringkern und vom Magazin entfernt angeordnete Fixierelement für den Drahtanfang diesen erst freigibt, wenn der angewickelte Ringkern in eine Stellung gedreht ist, in welcher der freigegebene Drahtanfang zwischen die Aufnahmehülse und den Ringkern geklemmt ist.When using this toroidal holder in a toroidal winding device known from DE-PS 2 820 674, this manual securing of the wire start is also omitted. In this preferred winding device, it is sufficient if the fixing element for the wire start, which is arranged away from the ring core and from the magazine, only releases the latter when the wound ring core is rotated into a position in which the released wire start is clamped between the receiving sleeve and the ring core.

Die Aufnahmehülse der Ringkern-Halterung kann - betrachtet in Hülsenlängsrichtung - zweigeteilt sein. Der lichte Querschnitt dieser und der einteiligen Aufnahmehülse ist selbstverständlich größer gewählt als der Querschnitt des Magazins.The receiving sleeve of the toroidal core holder can - viewed in the longitudinal direction of the sleeve - be divided into two. The clear cross-section of this and the one-piece receiving sleeve is of course chosen larger than the cross-section of the magazine.

Die vorstehend erläuterte Ringkern-Halterung trägt erheblich zur Automatisierung der Ringkern-Bewickelung bei.The toroidal holder explained above contributes significantly to the automation of the toroidal winding.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below using an exemplary embodiment.

Die Wickelvorrichtung nach Fig. 1 und 2 weist ein ringförmiges Magazin 1 auf, das bei 11 durch einen Spalt unterbrochen ist und auf seiner einen Stirnfläche zueinander beabstandete Gleitrollen 2 trägt. Bezugszeichen 5 bezeichnet einen Antrieb mit einem auf einer Welle drehbar gelagerten Treibrad 4, das mit weiteren, gleichfalls auf Wellen drehbar gelagerten Rädern 20, 22 (siehe Fig. 3) gegen die Außenmantelfläche eines in einer Ringkern-Halterung gemäß Fig. 3 bis 6 gehalterten Ringkernes 3 anliegt. Das Magazin 1, das als Ring, insbesondere Zahnkranz ausgebildet ist, wird in der Darstellung nach Fig. 2 in Pfeilrichtung A gedreht. Der Transport besteht hierbei aus einem Transportrad 15, das bei Rotation in Pfeilrichtung B über zwischengeschaltete Transporträder 13, 14 - die in Pfeilrichtung C rotieren - mit dem Zahnkranz des Magazins kämmt. Der Ringkern 3 und das Magazin 1 sind dabei um ihre senkrecht zueinander ausgerichteten rotationssymmetrischen Achsen drehbar. Die Elemente der Wickelvorrichtung sind zum Teil fest, zum Teil drehbar auf einer Montageplatte 12 angeordnet.1 and 2 has an annular magazine 1, which is interrupted at 11 by a gap and carries on its one end face spaced-apart rollers 2. Reference numeral 5 denotes a drive with a drive wheel 4 rotatably mounted on a shaft, which with further wheels 20, 22 (see FIG. 3) also rotatably mounted on shafts, against the outer surface of a ring-type holder according to FIGS. 3 to 6 Toroidal core 3 abuts. The magazine 1, which is designed as a ring, in particular a ring gear, is rotated in the direction of arrow A in the illustration according to FIG. 2. The transport consists of a transport wheel 15 which, when rotated in the direction of the arrow B, intermeshes with the toothed ring of the magazine via transport wheels 13, 14 which are connected in the direction of the arrow C and rotate. The toroidal core 3 and the magazine 1 can be rotated about their rotationally symmetrical axes oriented perpendicular to one another. The elements of the winding device are partly fixed, partly rotatable on a mounting plate 12.

Ein Wickeldraht 8 wird von einer in der Zeichnung nicht dargestellten Vorratsrolle abgezogen und mittels in Pfeilrichtung D entsprechend rotierender Transportrollen 6, 7 in Magazinrichtung befördert. Zum Fixieren des Drahtanfangs dient ein drehfest angeordnetes Klemmelement 9, das zum Magazin und zum Ringkern 3 beabstandet ist.A winding wire 8 is drawn off from a supply roll (not shown in the drawing) and conveyed in the magazine direction by means of transport rollers 6, 7 which rotate in the direction of the arrow D. A fixed clamping element 9, which is spaced from the magazine and the toroidal core 3, is used to fix the start of the wire.

Das Magazin 1, das zum Beispiel einen Zahnkranz aufweist und die Gleitrollen 2 sind in einer zur Zahnkranzmitte durchgehend geöffneten, drehfest angeordneten und in einem Bereich ihrer Länge unterbrochenen, in der Zeichnung nicht dargestellten schlauchringförmigen Verkleidung untergebracht, die im Bereich der Drahtzufuhr eine Drahtdurchführung besitzt.The magazine 1, which has, for example, a ring gear and the sliding rollers 2 are accommodated in a tubular ring-shaped covering, which is open to the center of the ring gear and is non-rotatably arranged and interrupted in an area of its length, which is not shown in the drawing and which has a wire feed-through in the area of the wire feed.

Im Inneren der nicht dargestellten Verkleidung befinden sich verstellbare Bürsten 10, die entsprechend dem gewünschten Wickelzug mit mehr oder weniger Druck auf dem magazinierten Draht aufliegen. Hierdurch ist es möglich, den Wickelzug, der bei Wickelbeginn zusätzlich durch den Abwickelzug von der Vorratsrolle erhöht ist und beim Leeren des Magazins merklich abnimmt, entsprechend zu steuern.In the interior of the cladding, not shown, there are adjustable brushes 10 which lie on the magazine wire with more or less pressure in accordance with the desired winding tension. This makes it possible to control the winding tension, which is additionally increased by the unwinding tension from the supply roll at the start of winding and which decreases noticeably when the magazine is emptied.

Die Ringkem-Halterung besitzt eine auf einem Schwenkarm 24 angeordnete Aufnahmehülse 30 (siehe Fig. 4) mit einem Ringflansch 32 für die Auflage des Ringkernes 3 und mit einem in Wickelstellung zur Magazinmitte hin offenen Bereich 31 ihrer Mantelfläche.The ring core holder has a receiving sleeve 30 arranged on a swivel arm 24 (see FIG. 4) with an annular flange 32 for supporting the toroidal core 3 and with an area 31 of its outer surface which is open towards the center of the magazine in the winding position.

In der Darstellung nach Fig. 3 ist der bei 25 schwenkbar gelagerte und durch eine Dämpfungseinrichtung 26, 27 in seiner Schwenkbewegung gedämpfte Schwenkarm 24 in die zur Magazinmitte - siehe Pfeilrichtung E - gerichtete Wickelstellung geschwenkt. Das Treibrad 4 und die weiteren Räder 20, 22 liegen dabei gegen die Außenmantelfläche des in Fig. 6 dargestellten und auf die Aufnahmehülse 30 aufgeschobenen Ringkernes 3 an.In the illustration according to FIG. 3, the swivel arm 24 pivotably mounted at 25 and damped in its swiveling movement by a damping device 26, 27 is swiveled into the winding position directed towards the center of the magazine - see direction of arrow E. The drive wheel 4 and the other wheels 20, 22 lie against the outer surface of the ring core 3 shown in FIG. 6 and pushed onto the receiving sleeve 30.

Fig. 6 zeigt bereits die Wickelstellung des Ringkernes 3, in welcher der Ringkern 3 mit seinem Wickeldrahtanfang aus dem offenen Bereich 31 der Mantelfläche der Aufnahmehülse 30 herausgedreht und folglich zwischen die Aufnahmehülse und den Ringkern geklemmt und damit gesichert ist.6 already shows the winding position of the toroidal core 3, in which the toroidal core 3 is turned with its winding wire beginning out of the open area 31 of the lateral surface of the receiving sleeve 30 and consequently is clamped between the receiving sleeve and the toroidal core and is thus secured.

Die Wirkungsweise dieser Wickelvorrichtung und die durch diese Vorrichtung erzielbaren Vorteile, insbesondere hinsichtlich Automatisierung und Aufwandminderung lassen sich durch folgendes Beispiel, das die Herstellung einer stromkompensierten Zweifach-Drossel beschreibt, veranschaulichen.

  • a) Es wird die Aufnahmehülse 30 mit aufgestecktem Ringkern 3 bei entsprechender Stellung des Magazins 1 in die Umlaufbahn des Magazins geschwenkt.
  • b) Es wird der Draht 8 zwischen zwei Gleitrollen 2 eingeschoben.
  • c) Der Drahtanfang wird im Klemmelement 9 fixiert.
  • d) Das Magazin wird zunächst langsam in Pfeilrichtung A transportiert und unter Drehung des Ringkerns 3 der am Ringkern angeschlagene Draht zwischen die Aufnahmehülse und den Ringkern geklemmt.
  • e) Der Drahtanfang wird freigegeben und die Rotationsgeschwindigkeit des Magazins gesteuert.
  • f) Der Draht wird von der Vorratsrolle abgetrennt.
  • g) Die Stellung der Bürsten wird dem gewünschten Wickelzug angepaßt und die Wickelgeschwindigkeit auf ihre Maximalgeschwindigkeit erhöht.
  • h) Die Rotationsbewegung des Magazins wird abgebremst und das Magazin langsam in die Ausgangsposition gefahren.
  • i) Das Magazin wird gestoppt.
  • j) Es werden der Drahtrest entfernt und anschließend der Kern weitergedreht.
  • k) Es folgen wiederum die Schritte a) bis h), wobei der Wickelsinn wahlweise umgekehrt werden kann.
The mode of operation of this winding device and the advantages which can be achieved by this device, in particular with regard to automation and reduction of expenditure, can be illustrated by the following example, which describes the production of a current-compensated double choke.
  • a) The receiving sleeve 30 with the ring core 3 attached is pivoted into the orbit of the magazine when the magazine 1 is in the appropriate position.
  • b) The wire 8 is inserted between two rollers 2.
  • c) The beginning of the wire is fixed in the clamping element 9.
  • d) The magazine is first slowly transported in the direction of arrow A and, with the ring core 3 rotated, the wire struck on the ring core is clamped between the receiving sleeve and the ring core.
  • e) The wire start is released and the rotation speed of the magazine is controlled.
  • f) The wire is separated from the supply roll.
  • g) The position of the brushes is adapted to the desired winding tension and the winding speed is increased to its maximum speed.
  • h) The rotational movement of the magazine is braked and the magazine is slowly moved into the starting position.
  • i) The magazine is stopped.
  • j) The wire residue is removed and the core is then rotated further.
  • k) Steps a) to h) follow again, with the winding direction optionally being reversed.

Beim vorstehenden Arbeitsablauf wird für den Zweifach-Drossel-Typ jede Wicklung getrennt magaziniert. Dadurch kann frei programmiert werden und zwar je nachdem, ob gleich- oder gegensinnige Wicklungen gewünscht sind; zum anderen muß das Magazin nur noch die halbe Drahtmenge aufnehmen und kann somit weiter verkleinert werden.In the above workflow, each winding is separately magazine for the double choke type. This means that programming can be carried out freely, depending on whether winding in the same direction or in the opposite direction is desired; on the other hand, the magazine only has to take up half the amount of wire and can therefore be further reduced.
