The catch or catches (8) move radially across and/or at an angle to the spindle axis (10). The catch(es) engage as the adaptor (2) is placed into position axially along the spindle.

Description

Die Erfindung betrifft einen in einer Garnspule verwendbaren Spulen-Adapter, der einen hohlzylindrischen Grundkörper zur Aufnahme einer Spindel und ein oder mehrere radial bewegbare Einrastmittel besitzt.The invention relates a bobbin adapter that can be used in a bobbin a hollow cylindrical base body for receiving a spindle and one or has several radially movable locking means.

Bei bekannten Vorrichtungen zur Spulenhalterung (vgl. DE-GM 74 09 733, DE-G 90 16 205.6 U1) wird die axiale Sicherung der Spulen auf der Spindel durch Verriegelung mittels eines Bajonette-Verschlußes herbeigeführt. Dabei gewährleisten in der Welle oder Spindel eingebrachte J-förmige Nuten und dazu komplementäre Stifte des Spulen-Adapters die Verriegelung. Zum Spulenwechsel wird mit einer Hand die Spule gegen die Kraft einer koaxialen Druckfeder nach unten gedrückt. Mit der anderen Hand wird der oben angeordnete Adapter erst geradlinig in die J-Nut eingeführt, und dann muß über eine Drehbewegung die Verriegelung bewirkt werden. Ist die koaxiale Druckfeder im oben angeordneten Adapter baulich integriert (vgl. DE-G 90 16 205.6 U1), muß bei dem genannten Bewegungsablauf der Bediener noch zusätzlich Kräfte zur Überwindung der Druckfeder ausüben. Vor allem die Notwendigkeit einer Drehbewegung bei diesem Bewegungsablauf ist ergonomisch nachteilig, insbesondere weil das Bedienungspersonal dies zum Spulenwechsel tagtäglich viele Male durchführen muß. Folglich sind bereits gesundheitliche Schäden im Handgelenk und in den Sehnen und sonstige ernsthafte Gesundheitsbeschwerden bei Durchführung dieser Arbeit zu beobachten gewesen. In known devices for coil holder (see. DE-GM 74 09 733, DE-G 90 16 205.6 U1) is the axial securing of the coils on the spindle brought about by locking by means of a bayonet catch. Ensure it J-shaped grooves made in the shaft or spindle and in addition complementary pins of the coil adapter locking. For changing bobbins the coil is moved with one hand against the force of a coaxial compression spring pressed down. With the other hand, the adapter located at the top becomes the first inserted straight into the J-groove, and then the Locking can be effected. The coaxial compression spring is arranged in the top The adapter is structurally integrated (cf. DE-G 90 16 205.6 U1) Movement sequence of the operator additionally forces to overcome the Apply compression spring. Above all, the need for a rotary movement with this Movement is ergonomically disadvantageous, especially because of the operating personnel this must be done many times a day to change the bobbin. As a result, there is already damage to the health of the wrist and tendons and other serious health problems when performing this work been observed.

Um bei einer Spulensicherung für Spinn- und Zwirnspindeln eine sichere axiale und radiale Halterung zu gewährleisten, eine gute und zentrische Führung der Spule sicherzustellen und eine unkomplizierte Handhabung bei der Bestückung und der Entnahme der Spule zu ermöglichen, ist bei einer bekannten Spulensicherung folgendes vorgesehen (DE-A-31 32 159): Ein unterer Adapter ist axial gegen die Kraft einer Feder verschiebbar ausgebildet. Ein oberer lösbarer Adapter ist mit mindestens zwei radial herausklappbaren, von einer Feder vorgespannten Haltesegmenten versehen. Die Haltesegmente tragen je einen im Bereich einer Spindelseele angeordneten Rasterstift, der beim Eindrücken des Adapters in die Spulenhülse in einer Nut der Spindelseele einrastet und die Spulenhülse axial sichert. Die Rasterstifte rasten beim Eindrücken des Adapters in die Spulenhülse in die Nut der Spindelseele ein und sichern so die Spulenhülse axial. Das Abnehmen der Spindelhülse geschieht dadurch, daß sie gegen die Kraft einer unteren Feder, welche den unteren Adapter beaufschlagt, nach unten gedrückt wird. Sobald die Spulenhülse über die Haltesegmente hinaus verschoben ist, werden diese frei und von den Federn radial nach außen geklappt. Dadurch verlassen die Rasterstifte die Ausnehmungen und die Nut und die Spindelhülse können zusammen mit dem Adapter von der Spindelseele abgenommen werden. Es kann also allein durch Drücken der Spindelhülse nach unten deren Lösen ausgelöst werden.To ensure a safe axial and with a spool lock for spinning and twisting spindles radial holder to ensure good and central guidance of the coil and uncomplicated handling during assembly and removal To enable the coil is the following with a known coil fuse provided (DE-A-31 32 159): A lower adapter is axially against the force of a spring slidably designed. An upper detachable adapter is radial with at least two fold-out, spring-loaded holding segments. The Holding segments each carry a raster pin arranged in the area of a spindle core, when the adapter is pressed into the coil sleeve in a groove in the spindle core engages and axially secures the coil sleeve. The grid pins snap when you press the Adapters into the coil sleeve in the groove of the spindle core and thus secure the coil sleeve axially. The removal of the spindle sleeve happens in that it against the Force of a lower spring, which acts on the lower adapter, pressed down becomes. As soon as the bobbin tube is moved beyond the holding segments, the springs are free and are folded radially outwards by the springs. Leave thereby the grid pins, the recesses and the groove and the spindle sleeve can be put together can be removed from the spindle core with the adapter. So it can do it alone by pressing the spindle sleeve downwards to release it.

Dem gegenüber liegt der Erfindung die Aufgabe zugrunde, einen Spulenadapter zu schaffen, mit dem nicht nur ein schneller und einfach handhabbarer Spulenwechsel in ergonomisch angepaßter bzw. den Menschen körperlich möglichst wenig belastenderweise durchgeführt werden kann, sondern auch eine erhöhte Zuverlässigkeit realisiert ist. Zur Lösung werden die in den Patentansprüchen 1, 4 und 6 angegebenen Spulenadapter nebengeordnet vorgeschlagen. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Patentansprüchen. In contrast, the invention has for its object to a coil adapter create with which not only a quick and easy to use spool change in ergonomically adapted or physically as little stressful as possible can be carried out, but also increased reliability realized is. The solution is the coil adapters specified in claims 1, 4 and 6 proposed as a subsidiary. Further advantageous configurations result itself from the dependent claims.

Die Einrastmittel stehen mit einer Lagerung, Anlenkung und/oder Führung in (Wirkungs-)Verbindung, die zur Rasteneinrichtung der Spindel der erfindungsgemäßen Vorrichtung gerichtet sind, dorthin auslaufen oder diese tangieren. Damit ist ein Mechanismus geschaffen, der für ein gegenüber der Spindelachse und/oder einer Axialebene der Spindel radiales, schräges oder quer verlaufenden Einrücken der Einrastmittel des Adapters in die Rasteneinrichtung der in dessen Grundkörper eingesteckten Spindel sorgt.The Locking means are available with storage, articulation and / or guidance (Active) connection to the locking device of the spindle of the invention Device are directed, leak there or tangent to it. In order to is a mechanism created for one against the spindle axis and / or an axial plane of the spindle radial, oblique or transverse Engaging the latching means of the adapter in the latching device in the Main body inserted spindle ensures.

Mit Vorteil sind ein oder mehrere Federelemente vorgesehen, die zumindest Wirkungskomponenten in gegenüber der Spindelachse und/oder einer Axialebene der Spindel schräger, querverlaufender und/oder radialer Richtung aufweisen und mit den Einrastmitteln baulich integriert oder zumindest gekoppelt sind. Die radialen, schrägen oder quer verlaufenden Wirkungskomponenten können dabei so eingesetzt werden, daß sie den Einrastmitteln Stellbewegungen erteilen, die zum Einrücken bzw. Eingriff in die Rasteneinrichtung der Spindel führen. Advantageously, one or more spring elements are provided, which are at least functional components in opposite to the spindle axis and / or an axial plane the spindle has an oblique, transverse and / or radial direction and are structurally integrated or at least coupled with the latching means. The radial, oblique or transverse active components can be so are used that they give the locking means actuating movements to Engage or engage in the locking device of the spindle.

Der erfindungsgemäße Adapter besitzt einen Schieber als Einrastmittel, der in einer Führung zumindest teilweise quer zur Zylinderachse bewegbar gelagert ist und eine Ringlasche mit mittiger Bohrung aufweist. Zweckmäßig ist die Bohrung der Ringlasche mit einem größeren Durchmesser ausgebildet als der Hohlraum des zylindrischen Grundkörpers des Adapters. Umfaßt im verriegelten Zustand die Ringlasche aufgrund ihres größeren Durchmessers die durchgeschobene Spindel exzentrisch, entsteht bei Rotation eine Zentrifugalkraft auf den exzentrischen bzw. asymmetrischen Teil des Schiebers, die zusätzlich die Verrastung zwischen Spulen-Adapter und Spindel fördert. Der Einsatz von Zentrifugal- bzw. Fliehkraftvorrichtungen zum Festklemmen von Spulen auf Spindeln in Textilmaschinen ist der Fachwelt an sich aus anderem technischen Zusammenhang (DE 35 46 260 A1) bekannt.The adapter according to the invention has a slide as a locking means, which is at least partially transverse in a guide is movably mounted to the cylinder axis and an annular plate with a central bore having. It is advisable to bore the ring plate with a larger diameter formed as the cavity of the cylindrical base body of the adapter. Covers the ring tab in the locked state due to its larger size Eccentric diameter of the inserted spindle arises during rotation a centrifugal force on the eccentric or asymmetrical part of the slide, which additionally promotes the locking between the coil adapter and the spindle. The use of centrifugal or centrifugal devices for clamping The bobbins on spindles in textile machines are in themselves different from the professional world technical context (DE 35 46 260 A1) known.

Zur weiteren Förderung der Verriegelung bzw. Verrastung ist nach einer zusätzlichen Erfindungsausbildung ein radial gerichtetes Federelement als Stelleinrichtung vorgesehen, das gegen den Grundkörper abgestützt ist und gegen den Schieber vorzugsweise nach radial außen drückt. Damit läßt sich im Zuge des axialen Aufsteckens des Adapters ein selbstätiges Einschnappen der Ringlasche beispielsweise in eine ringförmige Vertiefung auf dem Spindelmantel herbeiführen, was die Bedienung und Handhabbarkeit erleichtert und die Ergonomie weiter verbessert.To further promote the locking or latching is after an additional Invention training a radially directed spring element as an adjusting device provided that is supported against the base body and against the Pushes slide preferably radially outwards. This can be in the course of plugging the adapter axially into place, the ring clip automatically snaps into place for example lead into an annular recess on the spindle jacket, which facilitates operation and handling and ergonomics improved.

Nach einer anderen Alternative der Erfindung sind elastische Hakenteile, vorzugsweise kranz- oder ringartig angeordnet, vorgesehen, die mit dem einen Ende am Adapter-Grundkörper befestigt sind. Die Anlenkung ist dabei so ausgeführt, daß aufgrund der Elastizität eine federnde Schwenkbewegung der freien Hakenenden jeweils durch eine Aussparung in der Grundkörper-Innenwandung gegenüber der Spindelachse und/oder einer Axialebene der Spindel radial nach innen zum Hohlraum des Grundkörpers erfolgt. Hier wird ohne besonderen Verriegelungsmechanismus der Eingriff bzw. die Verrastung im wesentlichen durch die Elastizität der hakenartigen Federelemente und deren spezifische Anordnung an den Adapter-Grundkörper in Kombination mit der axialen Aufsteckbewegung erreicht. Um die Haken aus ihrer Verrastung mit der eingesteckten Spindel zu lösen, ist ein axial verschiebbar geführter Lösering oder -schieber zweckmäßig, der so an der Innenseite des Hakenfederelements angeordnet ist, daß bei entsprechender Schiebebewegung das Hakenteil gegenüber der Spindelachse und/oder einer Axialebene der Spindel schräg, quer und/oder radial nach außen verstellt wird.According to another alternative of the invention, elastic hook parts are preferred arranged like a wreath or ring, provided with one end are attached to the adapter base. The linkage is designed so that due to the elasticity a resilient pivoting movement of the free hook ends each through a recess in the inner wall of the base body the spindle axis and / or an axial plane of the spindle radially inwards to the cavity of the base body. Here is without a special locking mechanism the engagement or locking essentially by the Elasticity of the hook-like spring elements and their specific arrangement reached the adapter body in combination with the axial plug-on movement. To release the hooks from their engagement with the inserted spindle, is an axially displaceably guided release ring or slide, the so is arranged on the inside of the hook spring element, that with appropriate Sliding movement of the hook part against the spindle axis and / or one Axial plane of the spindle is adjusted obliquely, transversely and / or radially outwards.

Der einfachen Handhabung dient auch eine Ausbildung der Einrastelemente als Wälzelemente, insbesondere Kugeln, die in oder an der Grundkörperwandung axial und gegenüber der Spindelachse und/oder einer Axialebene der Spindel schräg, quer und/oder radial geführt und über den Zylinderumfangringartig verteilt angeordnet sind. Dabei kann als Stelleinrichtung ein Sicherungsring verwendet werden, welcher die Wälzelemente umfaßt und bei axialer Verschiebung zur oder von der Rasteneinrichtung auf der Spindel verstellt. Das selbständige Einrasten der Wälzelemente läßt sich mit Hilfe einer Federung herbeiführen, welche den Sicherungsring selbstätig in die Einraststellung für die Wälzelemente bewegt. Deren Ausrücken aus der Rasteneinrichtung auf der Spindel wird nach einer weiteren Ausbildung durch die Anordnung eines oder mehrerer, axial oder achsparallel wirkender Federelemente erleichtert. Diese sind in den Adapter-Grundkörper eingebaut und bilden ein Zwischenglied zwischen einem Adapter-Verriegelungsteil mit Einrastmitteln und einem Adapter-Spulenmitnahmeteil mit Eingriffsmitteln (zum Beispiel Reibflächen) für die Spule. Über die Federelemente können Verriegelungsteil und Spulenmitnahmeteil axial gegeneinander verstellt werden. Im Zusammenhang mit dem Ausrasten der oben genannten Wälzelemente unterstützen die zwischengeschalteten Federelemente vorteilhaft deren Ausrücken aus der Rasteneinrichtung der Spindel, wenn der Sicherungsring in eine Freigabestellung verschoben ist.The simple handling also serves as a design of the latching elements Rolling elements, in particular balls, in or on the base body wall axially and with respect to the spindle axis and / or an axial plane of the spindle guided obliquely, transversely and / or radially and arranged distributed over the circumference of the cylinder are. A locking ring can be used as an adjusting device which includes the rolling elements and with axial displacement to or from the Latching device adjusted on the spindle. The self-engaging of the rolling elements can be brought about with the aid of a suspension which holds the locking ring automatically moved into the engagement position for the rolling elements. Their Disengagement from the detent device on the spindle is another Training through the arrangement of one or more, acting axially or axially parallel Spring elements relieved. These are built into the adapter body and form an intermediate link between an adapter locking part Snap-in means and an adapter coil driving part with engagement means (for Example friction surfaces) for the coil. About the spring elements can locking part and coil driving part can be adjusted axially against each other. In connection support by disengaging the rolling elements mentioned above the intermediate spring elements advantageously disengage them from the Locking device of the spindle when the locking ring is in a release position is moved.

Gemäß Fig. 1 ist die Spindel 1 einer nicht näher gezeichneten Textilmaschine mit ihrem oberen Endbereich in den Hohlraum eines oberen Spulen-Adapters 2 mit hohlzylindrischer Grundform eingeschoben. Der obere Adapter 2 besteht im wesentlichen aus zwei zusammenhängenden gegeneinander axial verschiebbaren Teilen, nämlich dem oberen Verriegelungsteil 3 und dem unteren Spulenmitnahmeteil 4, der im Beispiel als hohlzylindrische Büchse mit im oberen Stirnbereich konischer Außenwandung 5 ausgeführt ist. Diese steht mit der gegenüberliegenden Innenwandung einer Garnspule 6 in reibschlüssigem Eingriff. Eine oder mehrere achsparallele oder koaxiale Druckfedern 7, die gegen die Unterseite des Verriegelungsteils 3 abgestützt sind, drücken den Spulenmitnahmeteil 4 mit seinem konischen Außenwandungsabschnitt 5 an die Innenwandung der Garnspule 6. Der Zusammenhang der genannten Teile 3 und 4 ist durch eine gegenseitige Verhakung 43 realisiert.1, the spindle 1 of a textile machine, not shown, is included their upper end area in the cavity of an upper coil adapter 2 with hollow cylindrical basic shape inserted. The upper adapter 2 consists essentially from two connected axially displaceable against each other Parts, namely the upper locking part 3 and the lower coil driving part 4, in the example as a hollow cylindrical sleeve with in the upper front area conical outer wall 5 is executed. This stands with the opposite Inner wall of a bobbin 6 in frictional engagement. One or more axially parallel or coaxial compression springs 7, which are against the underside of the locking part 3 are supported, press the coil driving part 4 with his conical outer wall section 5 to the inner wall of the yarn package 6. The connection between parts 3 and 4 is due to mutual interlocking 43 realized.

Der Verriegelung bzw. Verrastung des oberen Adapters 2 mit der Spindel 1 dient als Einrastmittel ein Querschieber 8, der gemäß Fig. 2 in einer Querführung 9 senkrecht zur Adapter-Zylinderachse 10 verschiebbar ist. Der Schieber 8 besitzt gemäß Fig. 2 eine ringartige Lasche 11 mit einer mittigen Bohrung 12, welche die Spindel 1 umgibt. Zu diesem Zweck besitzt die Bohrung 12 einen größeren Durchmesser als die Spindel 1. Letztere ist in ihrem dem Adapter 2 zugeordneten Bereich mit einer Ringnut 13 versehen, in die gemäß Fig. 1 die Lasche 11 mit einem Teil 11a des die Bohrung 12 begrenzenden Innenumfangs eingerückt ist. Dieses Einrücken kann im Zuge des axialen Aufsteckens des Adapters 2 auf die Spindel 1 aufgrund der Querfeder 14 selbstätig erfolgen, die gegen den Außenmantel des Adapter-Grundkörpers abgestützt auf die Innenseite eines Schenkels des Schiebers 8 mit L-artigem Grundprofil im Axialschnitt drückt. Im nicht aufgestecktem Zustand (nicht gezeichnet) würde die Bohrung 12 der Schieberlasche 11 durch die Querfeder 14 nach radial außen außer Deckung mit der Zylinderachse 10 des Adapters 2 verstellt. Das Aufstecken des Adapters 2 mit Schieber 8 wird durch eine umlaufende, vorzugsweise konische Schrägfläche 15 erleichtert, die am Spindelende 16 ausgebildet ist. Die Schrägfläche 15 bewirkt eine Zentrierung insbesondere des Schiebers 8 mit seiner Bohrung 12 derart, daß dieser in Verbindung mit dem Querdruck der Querfeder 14 in die Ringnut 13 der Spindel 1 einrasten kann. Mittels ein oder mehrerer achsparallelen Fixier- und/oder Anschlagstifte 17, der den Adapter-Grundkörper und gegebenenfalls auch die Lasche 11 durchsetzt, kann neben der zusätzlichen Arretierung bzw. Verriegelung noch ein Ausgleich rotatorisch- asymmetrischer Masseverteilungen im Adapter-Grundkörper bewirkt werden. Die asymmetrischen Masseverteilungen gehen insbesondere auf die spezififsche Ausbildung des Querschiebers 8 und der asymmetrischen Anordnung der Querfeder 14 zurück. Demgegenüber können die Anschlag- und/oder Fixierstifte 17 die Funktion von Auswuchtkörpern ausführen.The locking or latching of the upper adapter 2 with the spindle 1 is used as a latching means a cross slide 8, which according to FIG. 2 in a transverse guide 9 is displaceable perpendicular to the adapter cylinder axis 10. The slide 8 has 2 an annular tab 11 with a central bore 12 which the Surrounds spindle 1. For this purpose, the bore 12 has a larger one Diameter than the spindle 1. The latter is assigned to the adapter 2 Area provided with an annular groove 13 into which the tab 11 with a Part 11a of the inner circumference delimiting the bore 12 is indented. This engagement can take place in the course of the axial attachment of the adapter 2 Spindle 1 take place automatically due to the transverse spring 14, which against the outer jacket of the adapter body supported on the inside of a leg of the slide 8 with an L-like basic profile in axial section. Im not attached Condition (not shown) would be the bore 12 of the slide tab 11 through the transverse spring 14 radially outward out of alignment with the cylinder axis 10 of the adapter 2 adjusted. Plugging the adapter 2 with slider 8 will facilitated by a circumferential, preferably conical inclined surface 15 which is formed at the spindle end 16. The inclined surface 15 causes centering in particular the slide 8 with its bore 12 such that it is connected engage with the transverse pressure of the transverse spring 14 into the annular groove 13 of the spindle 1 can. Using one or more axially parallel fixing and / or stop pins 17, the adapter base body and possibly also the tab 11 enforced, in addition to the additional locking or locking Compensation of rotationally asymmetrical mass distributions in the adapter body be effected. The asymmetrical mass distributions go in particular on the specific design of the cross slide 8 and the asymmetrical Arrangement of the cross spring 14 back. In contrast, the stop and / or fixing pins 17 perform the function of balancing bodies.

Bei Spindeln ohne die genannte Schrägfläche kann die richtige Aufsteckposition durch manuellen Druck auf die Außenseite des Schiebers 8, wodurch dieser gegen die radial nach außen gerichtete Kraft der Querfeder 14 verschoben wird, erreicht werden. Zum Lösen der Verriegelung wird der Schieber 8 durch geringfügigen, manuellen Druck nach radial innen in eine Auslöseposition gebracht, in welcher die Fläche der mittigen Bohrung 12 den Querschnitt der Spindel 1 vollständig abdeckt bzw. die Lasche 11 die Ringnut bzw. die Spindel 1 nicht mehr berührt. Die Axial-Druckfeder 7 kann dann den Verriegelungsteil 3 gegenüber dem Mitnahmeteil 4 axial nach oben verschieben, um die Entriegelung bzw. Ausrastung des Schiebers 8 zu vollenden.The correct mounting position can be used for spindles without the inclined surface mentioned by manual pressure on the outside of the slide 8, whereby this against the radially outward force of the cross spring 14 is shifted reached become. To release the lock, the slider 8 is slightly manual pressure brought radially inward into a release position, in which the area of the central bore 12 completely the cross section of the spindle 1 covers or the tab 11 no longer touches the annular groove or the spindle 1. The axial compression spring 7 can then the locking part 3 with respect to the driving part 4 Move axially upwards to unlock or disengage to complete the slide 8.

Gemäß Fig. 3 ist am unteren Ende der Spule 6 ein unterer Spulenadapter 18 ebenfalls mit einer konischen Außenwandung 5 angeordnet. Die Federkraft der Axialdruckfeder 7 gemäß Fig. 1, die sich über den eingerasteten Schieber 8 gegen die Ringnut 13 abstützt, bewirkt Reibschluß zwischen den konischen Außenwandungen 5 des oberen Adapters 2 und des unteren Adapters 18 und der jeweiligen Innenwandung der Garnspule 6.3, at the lower end of the coil 6 is a lower coil adapter 18 also arranged with a conical outer wall 5. The spring force of the Axial compression spring 7 according to FIG. 1, which is against the latched slide 8 against the annular groove 13 supports, causes frictional engagement between the conical outer walls 5 of the upper adapter 2 and the lower adapter 18 and the respective Inner wall of the thread spool 6.

Gemäß Fig. 4a, 5a ist lediglich ein einziger Anschlag- und Fixierstift 17 vorgesehen, welcher den Verriegelungsteil 3 des Spulenadapters 2 achsparallel durchsetzt. Er bildet gleichsam ein Gegengewicht zur Querfeder 14 und den dadurch radial nach außen gedrückten Querschieber 8, wie insbesondere aus der in Fig. 5a gezeigten Stellung ersichtlich. In dieser Stellung ist der Einrastteil 11a der Ringlasche 11 in die Ringnut 13 eingerückt, und die mittige Bohrung 12 der Ringlasche 11 steht außer Deckung mit dem maximalen Querschnitt 100 der Spindel 1. In der Stellung nach Fig. 4b, 5b dagegen ist der Querschieber 8 bzw. die Ringlasche 11 beispielsweise mittels Fingerdruck gegen die Querfeder 14 radial nach innen derart gedrückt, daß sich die Bohrung 12 der Ringlasche 11 mit dem Spindelquerschnitt 100 so decken, daß der Spulenadapter 2 nach oben abgezogen werden kann, ohne daß ein Eingriffs- bzw. Einrückteil 11a der Ringlasche 11 dem im Wege stehen würde. Gemäß Fig. 4a, 4b besitzt der Fixier- und Anschlagstift 17 an seinem unteren, stirnseitigen Ende einen vorspringenden Anschlagzapfen 17a, der in ein Langloch 11b taucht, das zwischen dem äußeren Rand und der Bohrung 12 der Ringlasche ausgebildet ist. Die Längsrichtung des Langloches 11b verläuft etwa radial bezüglich der Bohrung 12 und/oder der Spindelachse 10. In der verriegelten Stellung gemäß Fig. 5a schlägt der Anschlagszapfen 17a im Langloch 11b etwa gegen dessen radial äußeres Ende, während in der Verriegelungsstellung 5b der gegen das radial innere Ende des Langloches 11b anliegt.4a, 5a, only a single stop and fixing pin 17 is provided, which passes through the locking part 3 of the coil adapter 2 axially parallel. It forms, as it were, a counterweight to the transverse spring 14 and thereby radially outwardly pushed cross slide 8, as in particular from the in Fig. 5a shown position. In this position, the latching part 11a of the ring plate 11 indented in the annular groove 13, and the central bore 12 of the ring plate 11 is out of register with the maximum cross section 100 of the spindle 1. In contrast, in the position according to FIGS. 4b, 5b, the cross slide 8 or the ring plate is 11 radially for example by finger pressure against the transverse spring 14 pressed inside such that the bore 12 of the ring plate 11 with the spindle cross section Cover 100 so that the coil adapter 2 is pulled upwards can be without an engaging or engaging part 11a of the ring plate 11 the would stand in the way. 4a, 4b has the fixing and stop pin 17th at its lower end face a projecting stop pin 17a, which plunges into an elongated hole 11b, which is between the outer edge and the bore 12 of the ring plate is formed. The longitudinal direction of the elongated hole 11b runs approximately radially with respect to the bore 12 and / or the spindle axis 10. In 5a strikes the stop pin 17a in the locked position Elongated hole 11b approximately against its radially outer end while in the locking position 5b which bears against the radially inner end of the elongated hole 11b.

Die Ausführung nach Fig. 6 dient dazu, auf einer einzigen Spindel 1 Garnspulen 6a, 6b unterschiedlicher Länge aufnehmen zu können. Zu diesem Zweck ist die Spindel 1 im axialen Abstand voneinander mit zwei Ringnuten 13a und 13b als Rasteneinrichtungen versehen. Die obere Ringnut 13b dient zur axialen Verriegelung der längeren Garnspule 6b, die untere Ringnut 13a zur Verriegelung der kürzeren Garnspule 6a. Wegen sonstiger Einzelheiten und der Funktionsweise kann auf die vorher erläuterten Ausführungsbeispiele entsprechend verwiesen werden.6 serves 1 spools of thread on a single spindle 6a, 6b of different lengths. For this purpose, the Spindle 1 at an axial distance from one another with two annular grooves 13a and 13b Provide locking devices. The upper annular groove 13b is used for axial locking the longer bobbin 6b, the lower ring groove 13a for locking the shorter one Yarn spool 6a. Because of other details and how it works reference is made accordingly to the previously explained exemplary embodiments.

Auch gemäß den weiteren Ausbildungen gemäß Fig. 7 - 11 ist zur Verriegelung oder Entriegelung nur eine geradlinige, axiale Bewegung 29 notwendig.Also according to the further training according to FIGS. 7-11 is for locking or unlocking only a straight, axial movement 29 necessary.

Gemäß Fig.7 erfolgt die Verriegelung mittels Einrastmittel, die als Kugelelemente 19 in kranz- oder ringartiger Anordnung mit gleichmäßiger Verteilung um die Zylinderachse 10 realisiert sind. Die Kugelelemente 19 werden im nicht verriegelten bzw. ausgerasteten Zustand beispielsweise in jeweils zugeordneten Führungstaschen 20 entsprechender, ringartiger Anordnung gehalten und unmittelbar vor Einrastung achsparallel zur Ringnut 13 der Spindel 1 geleitet. Dabei ist im Zuge des Aufsteckens des oberen Adapters 2 ein Sicherungsring 21 gegen den Druck einer oder mehrerer axialer oder achsparalleler Sicherungsfedern 22 nach oben geschoben. Damit werden den Kugelelementen 19 nicht mehr der Parallelabschnitt 23 der Sicherungsring-Innenwandung (parallel zur Zylinderachse 10), sondern der polygonal nachfolgende Schrägabschnitt 24 der Sicherungsring-Innenwandung gegenübergestellt. Der gegenüberliegende Schrägabschnitt 24 ermöglicht den Kugelelementen 19, in radialer Richtung nach außen zu treten, so daß sie aufgrund der Schwerkraftwirkung und des entstandenen Spieles nach unten auf die ringartige Auflageschulter 25 auftreffen können. Diese liegt bündig bzw. auf gleicher Höhe wie die untere Kante der Ringnut 13, die ähnlich wie nach Fig. 1 angeordnet ist. Sodann wird der beispielsweise manuell nach oben verschobene Sicherungsring 21 losgelassen und aufgrund der Schwerkraft und des Drucks der Sicherungsfeder 22 nach unten verfahren. Dabei gelangt der Innenwand-Parallelabschnitt des Sicherungsrings 21 in Anlage an die Kugelelemente 19, wodurch diese in die Ringnut 13 eingerückt werden. Eine radiale und somit auch axiale Bewegung der Kugelelemente 19 ist damit verhindert.According to Figure 7, the locking takes place by means of latching means, which are spherical elements 19 in a wreath or ring-like arrangement with an even distribution around the cylinder axis 10 are realized. The ball elements 19 are not locked or disengaged state, for example, in the associated guide pockets 20 corresponding, ring-like arrangement held and immediately in front Locking guided axially parallel to the annular groove 13 of the spindle 1. It is on the move of attaching the upper adapter 2 a locking ring 21 against the pressure one or more axial or axially parallel locking springs 22 upwards pushed. The spherical elements 19 no longer become the parallel section 23 of the circlip inner wall (parallel to the cylinder axis 10), but the polygonal subsequent inclined section 24 of the inner ring of the circlip juxtaposed. The opposite inclined section 24 allows the ball elements 19 to step outward in the radial direction, so that it due to the effect of gravity and the resulting game after can hit the ring-like support shoulder 25 below. This is flush or at the same level as the lower edge of the annular groove 13, which is similar to after Fig. 1 is arranged. Then the, for example, manually moved up Circlip 21 released and due to gravity and Move the pressure of the locking spring 22 downwards. The inner wall parallel section arrives the locking ring 21 in contact with the ball elements 19, whereby these are inserted into the annular groove 13. A radial and therefore axial movement of the ball elements 19 is thus also prevented.

Zum Lösen der Verriegelung und des oberen Spulenadapters 2 wird der Sicherungsring 21 wieder nach oben geschoben. Dabei entstehen axiale Federkräfte sowohl aufgrund der Sicherungsfeder 22 als auch der Druckfeder 7. Insbesondere aufgrund letzterer wird die Auflageschulter 25 nach oben gerückt, wobei die Kugelelemente 19 aus der Ringnut 13 herausgestoßen und in ihre Führungstaschen 20 zurückgeführt werden können. Neben der einfachen Handhabung bringt diese rotationssymmetrische Spulenhalterung weitere Vorteile wie einfache, kostengünstige Fertigung und Vermeidung von Unwuchten und somit von Zentrifugalkräften.To release the lock and the upper coil adapter 2, the locking ring 21 pushed up again. This creates axial spring forces both due to the locking spring 22 and the compression spring 7. In particular due to the latter, the support shoulder 25 is moved up, the ball elements 19 pushed out of the annular groove 13 and into their guide pockets 20 can be returned. In addition to the easy handling, this brings rotationally symmetrical coil holder further advantages such as simple, inexpensive Manufacture and avoidance of unbalance and thus centrifugal forces.

Gemäß Fig. 9 ist die untere Spulenhalterung 18 über Schraubmittel 26 lösbar auf die Spindelwelle aufgebracht. Diese formschlüssigen Verbindungselemente können in einfacher Weise die Kraft auf die Halterung übertragen. Bei Verschleiß der Reibfläche des Spulenmitnahmeteils 4 kann dieses nach Lösen der Schraubmittel 26 einfach ausgetauscht werden wie in Fig. 5 veranschaulicht. Bei der fest durch Kleben oder Pressen aufgebrachten Aufnahme (vgl. Fig. 3) wird diese vorzugsweise aus zwei Teilen gefertigt. Bei Verschleiß verbleibt der Kern auf der Welle, während ein äußerer Ring ausgetauscht wird.According to FIG. 9, the lower coil holder 18 can be detached via screwing means 26 the spindle shaft applied. These positive connection elements can simply transfer the force to the bracket. If the The friction surface of the coil driving part 4 can do this after loosening the screwing means 26 can be easily exchanged as illustrated in FIG. 5. At the firm through Adhesive or pressing applied receptacle (see. Fig. 3) is preferred made of two parts. The core remains on the shaft when worn, while an outer ring is being replaced.

Gemäß Fig. 10 sind die Einrastmittel als kranzartig um die Spindel 1 herum angeordnete Federhaken 27 ausgeführt. Deren oberer Schaftteil 28 ist an der Innenwandung des Verriegelungsteils befestigt. Durch diese Anlenkung kann der freie Hakenteil, wenn dem Adapter 2 bzw. 2a eine ausreichende Aufsteckbewegung 29 erteilt wird, in die Einkerbung 30 der Spindel 1 einschnappen bzw. einrasten. Diese verbreitert sich von der Oberkante 31 aus in Richtung zur Spindelmitte zunehmend, so daß die Oberkante 31 für das freie Hakenende der Federhaken 27 gleichsam einen Widerhaken bildet. Zum Lösen des Adapters 2 bzw. 2a wird ein zwischen Spindel 1 und Innenwandung des Adapters 2 bzw. 2a geführter Lösering 32 nach unten in Richtung zur Einkerbung 30 verschoben. Insbesondere aufgrund des etwa keilartigen Axialschnittprofils des Löserings 32 erfolgt mit zunehmender Verschiebung gemäß Aufsteckbewegung 29 eine Aufweitung der Federhaken 27 nach radial außen, so daß deren freie Hakenende außer Eingriff mit der Oberkante 31 bzw. dem Widerhaken der Einkerbung 30 gelangen. In diesem Zustand ist eine Abziehbewegung nach oben entgegengesetzt zur Aufsteckbewegung 29 nach unten möglich, um einen Austausch der Garnspule 6 vorzunehmen.According to FIG. 10, the latching means are arranged as a ring around the spindle 1 Spring hook 27 executed. Its upper shaft part 28 is on the inner wall of the locking part attached. Through this articulation the free Hook part if the adapter 2 or 2a has a sufficient plug-on movement 29 is granted, snap or snap into the notch 30 of the spindle 1. This increasingly widening from the upper edge 31 towards the center of the spindle, so that the upper edge 31 for the free hook end of the spring hook 27th as it were a barb. To release the adapter 2 or 2a is a Loosening ring guided between spindle 1 and inner wall of adapter 2 or 2a 32 moved down towards the notch 30. In particular due to the approximately wedge-like axial section profile of the release ring 32 takes place with increasing Displacement according to plug-on movement 29 an expansion of the spring hook 27 radially outward so that the free hook end of it out of engagement with the upper edge 31 or the barb of the notch 30. Is in this state a pull-off movement upwards opposite to the plug-on movement 29 possible downwards to replace the yarn package 6.

Gemäß linker Hälften der Fig. 10 und 11 ist die Axialdruckfeder 7 im Verriegelungsteil 3 des Spulenadapters 2 baulich integriert und erzeugt die zum Reibschluß zwischen konischer Außenwandung 5 und Innenseite der Garnspule 6 notwendige Axialkraft. Gemäß rechte Hälften der Fig. 10 und 11 ist im unteren Adapter 18a eine Axialdruckfeder 7a mit gleichartiger Funktion zur Herbeiführung des Reibschlußes zwischen konischen Außenwandungen 5 und Innenwandungen der Garnspulen 6 angeordnet. Dann kann im oberen Spulenadapter 2a eine Axialdruckfeder entfallen, muß aber nicht.10 and 11, the axial compression spring 7 is in the locking part 3 of the coil adapter 2 structurally integrated and generates the friction between the conical outer wall 5 and the inside of the yarn package 6 necessary axial force. According to the right halves of FIGS. 10 and 11 is in the lower Adapter 18a an axial compression spring 7a with a similar function for bringing about of the frictional connection between conical outer walls 5 and inner walls the bobbins 6 arranged. Then one can in the upper coil adapter 2a Axial compression spring is not required, but does not have to.
