Description

Die Erfindung betrifft einen Spulendorn-Halter der im Oberbegriff des Patentanspruchs 1 bekannten Art, siehe US-A-3 391 889.The invention relates to a mandrel holder in the preamble of the known type of claim 1, see US-A-3 391 889.

Bei einem aus einem allgemeinen Katalog "Gestelle und Spulenhalter" der Fa. ROJ Electrotex bekannten Spulendorn-Halter für vertikale Gestellstreben (S. I3, S. I5), ist der Lagerbock nicht radial am Außenumfang der Ringfassung angeordnet. Die Aufnahme ist eine Sackbohrung mit in etwa zur Halterachse radialer Bohrungsachse. Eine in etwa tangential zum Umfang der Ringfassung in eine Gewindebohrung einschraubbares Fixierschraube dient zum Festlegen des in die Aufnahme eingesteckten Spulendorns. Der Lagerbock kragt bei dem bekannten Halter weit aus. Es ergibt sich eine nur kurze Stützlänge für den Spulendorn. Ferner läßt sich in manchen Fällen der Spulendorn nicht weit genug in die Aufnahme einschieben, um eine Spule optimal zu haltern. Es ergeben sich bei schweren Spulen lokale Belastungen, die zu einem frühzeitigen Verschleiß der Aufnahme, zu hohen Spannungen im Übergang vom Lagerbock zur Ringfassung und zu vibrierender Spule führen können. Zum Spulenwechsel läßt sich die Ringfassung relativ zum Hülsenkörper gegen die Haltewirkung der Federverrastung beiseite schwenken. Der Halter ermöglicht jedoch nur eine einzige Position für den Spulendorn, die durch die Position des Halters an der Gestellstrebe festgelegt ist.For one from a general catalog "Racks and spool holders" known from the company ROJ Electrotex for vertical frame struts (p. I3, p. I5) is the bearing block not arranged radially on the outer circumference of the ring frame. The receptacle is a blind bore with approximately the axis of the holder radial bore axis. One roughly tangent to the circumference the ring socket can be screwed into a threaded hole is used to define the inserted in the recording Spool. The pedestal protrudes from the known one Bracket wide. There is only a short support length for the spool. Furthermore, the Do not insert the mandrel far enough into the holder to to optimally hold a spool. It results in severe Coils local loads that cause premature wear the intake, too high tensions in the transition from the bearing block lead to the ring holder and vibrating coil. The ring holder can be changed relative to the spool Set the sleeve body aside against the retaining action of the spring catch swing. However, the holder allows only one Position for the mandrel, which is determined by the position of the Holder is fixed to the frame strut.

Es ist zwar aus demselben Katalog, S. I2 und S. I5 ein Spulendorn-Halter für horizontale Gestellstreben bekannt, bei dem die Aufnahme in einem seitlich von der Ringfassung abstehenden Lagerbock und beidendig offen ausgebildet ist, so daß sich der Spulendorn von der einen oder der anderen Seite in die Aufnahme einstecken läßt. Die Ringfassung ist bei festgelegtem Halter aus der durch das Gewicht der Spule gehaltener Arbeitsstellung in einer Richtung leicht verdrehbar (Spulenwechsel). Um den Spulendorn an der anderen Seite der Gestellstrebe haltern zu können, ist es erforderlich, den Halter auf der Gestellstrebe zu lösen und insgesamt zu verdrehen. Ungünstig ist ferner, daß der Spulendorn mit zwei Klemmschrauben zwischen zwei Klemmflanschen gehalten wird. Dies erfordert mühselige und zeitaufwendige Manipulationen zum Festlegen und Lösen des Spulendorns und die Lebensdauer beeinträchtigende Verformungen der Klemmflansche. Schließlich ist der Seitenabstand des Spulendorns von der Gestellstrebe verhältnismäßig groß, so daß bei schweren Spulen große Belastungen und exzentrische Kräfte auftreten, die die Halterung des Halters auf der Gestellstrebe beeinträchtigen und das Material des Halters ermüden. Der verhältnismäßig große Abstand des Spulendorns von der Achse der Gestellstrebe begünstigt ferner ein Vibrieren der angeordneten Spule.Although it is from the same catalog, p. I2 and p. I5, a mandrel holder known for horizontal frame struts, at which the recording in a laterally protruding from the ring setting Bearing bracket and open at both ends, so that the mandrel from one side or the other has the receptacle plugged in. The ring setting is fixed Holder from the one held by the weight of the spool Working position easily rotatable in one direction (Spool change). To the mandrel on the other side of the To be able to hold the frame strut, it is necessary to Loosen the holder on the frame strut and twist it altogether. It is also unfavorable that the mandrel with two Clamping screws are held between two clamping flanges. This requires laborious and time-consuming manipulations for setting and releasing the spool and the service life impairing deformations of the clamping flanges. Finally is the side distance of the spool from the frame strut relatively large, so that heavy loads on heavy coils and eccentric forces occur that hold the bracket of the holder on the frame strut and affect the material tired of the holder. The relatively large distance of the coil mandrel favored by the axis of the frame strut a vibration of the arranged coil.

Der Erfindung liegt die Aufgabe zugrunde, einen Spulendorn-halter der eingangs genannten Art zuschaffen, der sich für horizontale und vertikale Gestellstreben gleichermaßen eignet, das rasche Wegschwenken der Spule zum Spulentausch ohne Lösen von Befestigungsmitteln erlaubt, kompakte Abmessungen besitzt und eine stabile und platzsparende Abstützung des Spulendorns ermöglichen. Der Halter soll es ermöglichen soll, einen Spulendorn ohne aufwendige Manipulationen entweder an der einen oder an der anderen Seite der Gestellstrebe positionieren zu können, um beengten Platzverhältnissen leichter Rechnung zu tragen bzw. eine optimale Fadenablaufgeometrie zuzulassen.The invention has for its object a mandrel holder of the type mentioned at the beginning, which is suitable for horizontal and vertical frame struts are equally suitable, the swivel away of the spool to swap the spool without Loosening of fasteners allows compact dimensions has and a stable and space-saving support of the Allow spool mandrel. The holder should enable a spool without any complex manipulation either position one or the other side of the frame strut to be able to make confined spaces easier To take into account or an optimal thread outlet geometry allow.

Die gestellte Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst.The task is with the features of the claim 1 solved.

Der Halter ist kompakt, bedienungsfreundlich und ermöglicht eine besonders stabile und platzsparende Abstützung des Spulendorns an jeder Gestellstrebe. Die Bohrung nutzt nämlich den Raum im Fleisch der Ringfassung und liegt demzufolge günstig nahe an der Gestellstrebe. Der Lagerbock ragt nur wenig nach außen. Der Spulendorn wird nahe an der Gestellstrebe abgestützt. Der Halter läßt sich sowohl für vertikale als auch für horizontale Gestellstreben benutzen Der kurze Hebelarm der langen Bohrung gegenüber der Achse der Ringfassung spart nicht nur Platz, sondern führt zu einer stabilen Abstützung der Masse der Spule bei oder gegen Erschütterungen.The holder is compact, easy to use and enables a particularly stable and space-saving support for the spool on each frame strut. The bore uses namely the space in the flesh of the ring setting and is therefore convenient close to the frame strut. The bearing block protrudes only a little outward. The spool is supported close to the frame strut. The holder can be used for both vertical and use for horizontal frame struts The short lever arm the long hole opposite the axis of the ring setting saves not only space, but leads to a stable support the mass of the coil during or against vibrations.

Da die Bohrung gemäß Anspruch 2 extrem lang ist, wobei sie mit ihren die Ringfassung verlassenden Endabschnitten im Lagerbock verläuft, steht eine sehr große Stützlänge für den Spulendorn zur Verfügung. Die beidendig offene Bohrung läßt es zu, den Spulendorn, bzw. eigentlich den Fußteil des Spulendorns, so weit einzuschieben, wie dies für eine optimale und stabile Halterung der Spule zweckmäßig ist. Gegebenenfalls steht das freie Ende des Spulendorns sogar aus der Bohrung vor. Der Spulendorn kann von jedem Ende der Bohrung eingeführt werden, so daß die Ringfassung - falls es die Platzverhältnisse oder die Fadengeometrie erfordern - um 180° verdreht werden kann, um den Spulendorn an der anderen Seite der Gestellstrebe abzustützen. Die Fixierschraube ist bequem handhabbar, da sie optimal zugänglich plaziert ist. Die Verdrehbarkeit der Ringfassung und die Federverrastung haben eine Doppelfunktion, da sie einerseits eine bequeme Handhabung bei einem Spulentausch ermöglichen, weil nur die Ringfassung entsprechend weit aus der Arbeitsposition verdreht zu werden braucht, und andererseits die Ringfassung auch um 180° gedreht werden kann, um den Spulendorn an der anderen Seite der Gestellstreben zu positionieren.Since the bore according to claim 2 is extremely long, it with their end sections leaving the ring frame in the bearing block runs, there is a very large support length for the Coil mandrel available. The open bore at both ends leaves it, the coil mandrel, or actually the foot part of the coil mandrel, insert as far as this for optimal and stable support of the coil is appropriate. Possibly the free end of the spool is even out of the hole in front. The spool can be inserted from either end of the hole be so that the ring setting - if there is space or require the thread geometry - rotated by 180 ° can be to the mandrel on the other side of the Support the brace. The fixing screw is convenient manageable, since it is placed in an optimally accessible place. The rotatability the ring setting and the spring catch have one Double function because it is easy to use allow when changing bobbins because only the ring holder to be rotated accordingly far from the working position needs, and on the other hand the ring setting also rotated by 180 ° can be to the mandrel on the other side of the Position frame braces.

Die Ausführungsform gemäß Anspruch 3 ist vorteilhaft, weil der Fortsatz des Lagerbocks genügend Fleisch für die Fixierschraube in der Gewindebohrung sicherstellt, ohne die kompakten Abmessungen des Halters nennenswert zu vergrößern. The embodiment according to claim 3 is advantageous because the extension of the pedestal has enough meat for the fixing screw ensures in the threaded hole without the compact Significantly increase the dimensions of the holder.

Besonders zweckmäßig ist die Ausführungsform gemäß Anspruch 4, weil auch nach langer Standzeit kein Ausleiern des Gewindes zu befürchten ist.The embodiment according to claim is particularly expedient 4 because the thread does not wear out even after a long service life is to be feared.

Die Ausführungsform gemäß Anspruch 5 hat den Vorteil, daß die Ringfassung zwei diametral gegenüberliegende feste Drehpositionen hat, in denen der Spulendorn abstützbar ist. Es läßt sich somit der Spulendorn, falls es der Platz oder die Fadengeometrie erfordern, von einer Seite der Gestellstrebe auf die andere Seite umsetzen ohne die Halterung lösen zu müssen.The embodiment according to claim 5 has the advantage that the Ring setting two diametrically opposite fixed turning positions in which the spool can be supported. It leaves the spool, if there is space or the thread geometry require from one side of the frame strut move the other side without having to loosen the bracket.

Eine herstellungstechnisch und montagetechnisch günstige Ausführungsform geht aus Anspruch 6 hervor. Die Federverrastung läßt sich problemlos innerhalb der kompakten Abmessungen der Ringfassung und des Hülsenkörpers unterbringen. Mit der C-förmigen Feder weden hohe Haltekräfte für stabile Drehpositionen der Ringfassung erreicht, sobald die Wälzkörper in die Rastvertiefungen eingreifen.A manufacturing technology and assembly technology favorable embodiment emerges from claim 6. The spring catch can be easily within the compact dimensions of the Place the ring frame and the sleeve body. With the C-shaped Spring hold high holding forces for stable turning positions the ring setting is reached as soon as the rolling elements in the Intervene with recesses.

Eine besonders stabile Fixierung des Halters auf der Gestellstrebe ist bei der Ausführungsform gemäß Anspruch 7 möglich. Ferner sind die Kappen und die Fixierung der Kappen und des Hülsenkörpers an der Gestellstreben herstellungs- und montagetechnisch zweckmäßig.A particularly stable fixation of the holder on the frame strut is possible in the embodiment according to claim 7. Furthermore, the caps and the fixation of the caps and the Sleeve body on the frame struts manufacturing and assembly technology expedient.

Die Ausführungsform gemäß Anspruch 8 dient zum Festlegen eines Spulendorns senkrecht zur Achse der Gestellstrebe.The embodiment according to claim 8 is used to define a Spool mandrel perpendicular to the axis of the frame strut.

Herstellungstechnisch und in bezug auf die Lebensdauer und das Gewicht sind die Ausführungsformen der Ansprüche 9 und 10 vorteilhaft.Technically and in terms of service life and the weight are the embodiments of claims 9 and 10 advantageous.

Ein Spulengestell C gemäß Fig. 1, wie es beispielsweise an mit Fadenliefergeräten ausgestatteten Webmaschinen benutzt wird, um die ggfs. voluminösen und schweren Fadenspulen abzustützen, weist beispielsweise vier vertikale Gestellstreben 1, 2, 3, 4 auf, die über einen Fußteil 5 mit einem Standfuß 6 und Laufrädern 7 miteinander verbunden sind. Sind nur vertikale Gestellstreben vorgesehen, dann ist zweckmäßigerweise auch ein nicht gezeigtes Kopfteil vorhanden, um das Gestell stabil auszusteifen. Es ist aber auch denkbar, horizontale Gestellstreben vorzusehen, beispielsweise wie die Gestellstrebe 11, die aussteifend wirken und ebenfalls die Halterung von Spulen ermöglichen. Das Spulengestell C kann in mehrere Etagen unterteilt werden, und zwar mittels Trennplatten P, die an Trennplatten-Haltern der Gestellstreben 8 abnehmbar angebracht sind. Üblicherweise handelt es sich um ein Spulengestell (Fig. 1 unterer Teil) nur mit vertikalen Gestellstreben, aus denen alle Spulen gehaltert werden, und mit übereinanderliegenden Etagen, oder um ein Spulengestell nur mit horizontalen Gestellstreben (wie in Fig. 1 oben) zum Abstützen der Spulen, und nebeneinanderliegenden Fächern, getrennt durch hängende Trennplatten. Die jeweils zum Abstützen der Spulen vorgesehenen Gestellstreben sind natürlich mit weiteren Gestellstreben zu einem selbsttragenden Gebilde verbunden, wobei die weiteren Gestellstreben nicht zum Abstützen von Spulen genutzt werden. Aber auch die in Fig. 1 gezeigte Mischform mit horizontalen und vertikalen Gestellstreben, die das Gestell definieren und zum Abstützen von Spulen dienen ist praktikabel.A bobbin frame C according to FIG. 1, as is the case, for example looms equipped with thread delivery devices to support the possibly voluminous and heavy thread spools, has, for example, four vertical frame struts 1, 2, 3, 4, which have a base 5 with a base 6 and impellers 7 are connected to each other. Are only vertical Frame struts provided, then it is appropriate there is also a head part, not shown, around the frame stiffen stably. But it is also conceivable to use horizontal To provide frame struts, such as the frame strut 11, which act stiffening and also the bracket of coils. The coil frame C can be divided into several Floors are divided, namely by means of partition plates P, the removable on the plate brackets of the frame struts 8 are attached. It is usually a coil frame (Fig. 1 lower part) only with vertical frame struts, from which all coils are held, and with superimposed ones Tiers, or around a bobbin rack only with horizontal Frame struts (as in Fig. 1 above) for support of the coils, and adjacent compartments, separately by hanging partition plates. Each for supporting the Coil-provided rack struts are of course with other Frame struts connected to a self-supporting structure, the other frame struts are not for support be used by coils. But also the one shown in Fig. 1 Mixed form with horizontal and vertical frame struts define the frame and serve to support coils is workable.

Zum Haltern der Spulen 10 mit ihren Spulendornen 9 sind an den Gestellstreben Spulendorn-Halter H angebracht, die im Detail aus den Fig. 2 und 3 zu entnehmen sind. Die beiden Gestellstreben 3 und 4 sind über Einsätze 13 miteinander verbunden, in denen Ablaufösen 14 für den jeweiligen Faden angeordnet sind.To hold the coils 10 with their spindles 9 are on attached to the rack strut mandrel holder H, which in detail 2 and 3 can be seen. The two frame struts 3 and 4 are connected to one another via inserts 13, in which drain eyelets 14 are arranged for the respective thread are.

Bei der in Fig. 1 in der Mitte angedeuteten Spule 10 ist erkennbar, daß der Halter so festgelegt ist, daß die Achse der Spule 10 bzw. deren Spulendorns in etwa zur zugehörigen Ablauföse weist. Der Halter H weist (Fig. 2 und 3) eine Ringfassung (Fig. 2) auf, die sich um 180° verdrehen läßt, um den Spulendorn 9' an der anderen Seite der Gestellstrebe 1 zu positionieren, z.B. aus Platzgründen und/oder wegen der Fadenablaufgeometrie. Ferner läßt sich der Spulendorn 9 mit der Ringfassung in Richtung eines Doppelpfeiles 12 zu einem Spulenwechsel beliebig weit hin- und herschwenken. Nach einem Spulenwechsel wird die neue Spule mit dem Spulendorn wieder in die jeweilige Arbeitslage zurückgeschwenkt und durch den Halter fixiert.The coil 10 indicated in the middle in FIG. 1 shows that the holder is set so that the axis of the Spool 10 or its spool mandrel approximately to the associated drain eyelet points. The holder H has (Fig. 2 and 3) a ring setting (Fig. 2), which can be rotated by 180 ° to the Position the mandrel 9 'on the other side of the frame strut 1, e.g. for space reasons and / or because of the thread drain geometry. Furthermore, the mandrel 9 with the Ring holder in the direction of a double arrow 12 for a coil change Swing back and forth as far as you want. After one The new bobbin with the bobbin mandrel will change the bobbin again pivoted back into the respective working position and by the Holder fixed.

Gemäß den Fig. 2 und 3 weist der Halter H einen inneren Hülsenkörper 15 auf, der an der Gestellstrebe 1 bis 4, 11, z.B. mit einer Fixierschraube 35, festgelegt ist. In einem axial begrenzten Längsbereich des Spulenkörpers 15 sind außen zwei diametral gegenüberliegende Rastvertiefungen 16 eingeformt. Zumindest ein Ende des Hülsenkörpers 15 enthält eine radiale Bohrung 17 (gegebenenfalls eine Gewindebohrung) für die Fixierschraube 35. An einer zur Bohrung 17 in Umfangsrichtung versetzten Stelle ist eine Aufnahme 18 eingeformt. 2 and 3, the holder H has an inner sleeve body 15 on the frame strut 1 to 4, 11, e.g. is fixed with a fixing screw 35. In an axial limited longitudinal area of the bobbin 15 are two on the outside diametrically opposed locking recesses 16 are formed. At least one end of the sleeve body 15 contains a radial one Hole 17 (a threaded hole if necessary) for the fixing screw 35. At one to the bore 17 in the circumferential direction a receptacle 18 is formed in the offset point.

Auf dem Hülsenkörper 15 ist drehbar eine konzentrische Ringfassung 19 angeordnet, die einen quer zur Achse der Ringfassung 19 verlaufenden, einstückig angeformten Lagerbock 20 trägt, der in etwa mittig einen nach außen ragenden Fortsatz 21 besitzt. In den Fortsatz 21 und den Lagerbock 20 ist ein Gewindeeinsatz 22 eingebettet, der eine Gewindebohrung 23 für eine nicht dargestellte Fixierschraube aufweist. Die Gewindebohrung 23 mündet in eine Aufnahme A für einen nicht gezeigten Spulendorn 9. Die Aufnahme A ist eine in Umfangsrichtung geschlossene, beidendig offene Längsbohrung 24 im Lagerbock 20, wobei die Bohrung 24 einen in Fig. 3 kreisabschnittförmigen Mittellängsabschnitt M besitzt, der innerhalb der Ringfassung 19 liegt. Die Bohrungsachse 25 befindet sich demzufolge nahe an dem Hülsenkörper 15 bzw. der Gestellstrebe.A concentric ring mount is rotatable on the sleeve body 15 19 arranged a transverse to the axis of the ring frame 19 extending, integrally molded bearing block 20 bears an extension projecting approximately in the middle 21 owns. In the extension 21 and the bracket 20 is a Threaded insert 22 embedded, which is a threaded bore 23 for has a fixing screw, not shown. The threaded hole 23 opens into a receptacle A for a not shown Spool mandrel 9. The receptacle A is one in the circumferential direction closed, open at both ends longitudinal bore 24 in the bearing block 20, the bore 24 being a circular segment in FIG. 3 Has central longitudinal section M, which is within the ring frame 19 lies. The bore axis 25 is therefore located close to the sleeve body 15 or the frame strut.

Die Bohrungsachse 25 verläuft mit dem Lagerbock 20 senkrecht zur Achse der Gestellstrebe, so wie dies in der Fig. 4 angedeutet ist.The bore axis 25 runs vertically with the bearing block 20 to the axis of the frame strut, as indicated in FIG. 4 is.

Der Hülsenkörper 15 weist eine Umfangsschulter 26 auf, die mit einer inneren Schulter 27 der Ringfassung 19 zusammenarbeitet, um diese axial zu sichern. Die Ringfassung 19 wird in Fig. 2 von oben auf den Hülsenkörper 15 aufgefädelt.The sleeve body 15 has a circumferential shoulder 26 which cooperates with an inner shoulder 27 of the ring holder 19, to secure them axially. The ring frame 19 is in Fig. 2 threaded onto the sleeve body 15 from above.

Die Ringfassung 19 ist innen mit taschenförmigen Hohlräumen und Versteifungsrippen ausgestattet, so daß sich eine innere Schürze 28 ergibt, die bis über den Bereich der Rastvertiefungen 16 im Hülsenkörper 15 reicht. In den Rastvertiefungen 16 sind (in der Haltestellung bzw. der fixierten Drehposition der Ringfassung 19) zwei Wälzkörper 29 gelagert (z.B. tonnenförmig oder kugelförmig sind). Jeder Wälzkörper 29 steht aus der Rastvertiefung 16 nach außen vor und greift in eine Umfangsausnehmung 39 der Schürze 28 ein. Außen liegt auf den Wälzkörpern 29 eine C-förmige Feder 30 mit Vorspannung auf, die die Wälzkörper 29 in den Rastvertiefungen 16 festhält. The ring holder 19 is inside with pocket-shaped cavities and stiffening ribs so that there is an inner Apron 28 results in that over the area of the recesses 16 in the sleeve body 15 is sufficient. In the recesses 16 (in the stop position or the fixed rotational position the ring socket 19) two rolling elements 29 are mounted (e.g. barrel-shaped or are spherical). Each rolling element 29 is pending the recess 16 in front and engages in a circumferential recess 39 of the apron 28. Outside lies on the Rolling elements 29 have a C-shaped spring 30 with pretension, which holds the rolling elements 29 in the locking recesses 16.

Außerhalb der Feder 30 ist in der Ringfassung 19 ein radialer Expansionsraum 31 vorgesehen, dessen radiale Weite so bemessen ist, daß die Feder 30 nachgeben kann, wenn die Wälzkörper 29 aus den Rastvertiefungen 16 austreten wollen.Outside the spring 30 is in the ring 19 a radial Expansion space 31 is provided, the radial width so dimensioned is that the spring 30 can yield when the rolling elements 29 want to emerge from the recesses 16.

An beiden Enden des die Ringfassung 19 überragenden Hülsenkörpers 15 sind kreisringförmige Kappen 32, 33 angebracht, entweder nur aufgesteckt oder mittels Sicherungsbolzen 37 verdreh- und abziehfest gesichert. In der Kappe 32 ist eine Radialbohrung 36 erkennbar, in die der Sicherungsbolzen 37 so weit eingesetzt und, z.B. durch Verkleben, gesichert ist, daß er mit seinem innenliegenden Ende bis in die Aufnahme 18 eintritt. Ferner ist in der Kappe 32 eine Gewindebohrung 34 für die Fixierschraube 35 vorgesehen, die sich gegen den Umfang der Gestellstrebe 1 bis 4, 11 spannen läßt und damit die Position des Hülsenkörpers 15 an der Gestellstrebe festlegt. Zwischen den Rastvertiefungen 16 sind auf dem Hülsenkörper 15 Auflagen 38 für die Wälzkörper 29 geformt.At both ends of the sleeve body projecting beyond the ring socket 19 15 annular caps 32, 33 are attached, either only plugged in or by means of securing bolts 37 secured against twisting and peeling. In the cap 32 is one Radial bore 36 can be seen in which the securing bolt 37 so widely used and, e.g. by gluing, it is ensured that it enters the receptacle 18 with its inner end. Furthermore, a threaded bore 34 is in the cap 32 for the fixing screw 35 is provided, which is against the circumference the frame strut 1 to 4, 11 can tension and thus the position of the sleeve body 15 on the frame strut. Between the locking recesses 16 are on the sleeve body 15 Pads 38 shaped for the rolling elements 29.

Bei gemäß Fig. 2 und 3 in die Rastvertiefungen 16 hineingedrückten Wälzkörpern 29 ist die Ringfassung 19 in einer bestimmten Drehposition auf dem Hülsenkörper 15 festgelegt. Der Spulendorn 9 ist in die Bohrung 24 so weit eingeschoben, wie dies für die optimale Positionierung der Spule für erforderlich gehalten wird, und mittels einer in die Gewindebohrung 23 eingeschraubten Fixierschraube festgelegt. Zu einem Spulenwechsel wird mittels des Spulendorns die Ringfassung 19 relativ zum Hülsenkörper 15 verdreht. Dabei werden durch die schrägen Rampen, die die Rastvertiefungen 16 begrenzen, die Wälzkörper 29 aus den Rastvertiefungen 16 ausgehoben und durch die Umfangsausnehmungen 39 in der Schürze 28 der Ringfassung 19 entlang der Auflagen 38 in Drehrichtung verschoben. Die Feder 30 expandiert in den Expansionsraum 31. Die Reibung der Wälzkörper 29 unter der Kraft der Feder 30 reicht aus, die verdrehte Ringfassung 19 bei einem Spulenwechsel zu positionieren. Ist eine neue Spule aufgesetzt, dann wird mittels des Spulendorns die Ringfassung wieder in die ursprüngliche Position zurückgedreht, bis die Wälzkörper 29 in die Rastvertiefungen 16 einfallen. Soll der Spulendorn an die andere Seite der Gestellstrebe gebracht werden, dann wird die Ringfassung um 180° verdreht, bis die Wälzkörper 29 wieder in die Rastvertiefungen einfallen. Der Spulendorn 9 wird dann vom anderen Ende der Bohrung 24 in diese eingesteckt und fixiert.2 and 3 pressed into the locking recesses 16 Rolling bodies 29 is the ring socket 19 in a certain Set rotational position on the sleeve body 15. The Spool mandrel 9 is inserted into the bore 24 as far as this is necessary for the optimal positioning of the coil is held, and by means of a in the threaded bore 23 screwed fixing screw. For a bobbin change is the ring socket 19 by means of the coil mandrel rotated relative to the sleeve body 15. In doing so, the inclined ramps that delimit the recesses 16 that Rolling elements 29 are lifted out of the locking recesses 16 and through the circumferential recesses 39 in the apron 28 of the ring frame 19 moved along the supports 38 in the direction of rotation. The spring 30 expands into the expansion space 31. Die Friction of the rolling elements 29 under the force of the spring 30 is sufficient off, the twisted ring socket 19 when changing the spool position. If a new bobbin is attached, use the the ring mandrel back into the original Turned back position until the rolling elements 29 in the Engaging recesses 16. Shall the mandrel go to the other Side of the frame strut, then the Ring setting rotated by 180 ° until the rolling elements 29 in again the recesses come in. The mandrel 9 is then from the other end of the hole 24 inserted into it and fixed.
