Derartige Offenend-Spinnvorrichtungen sind beispielsweise durch die DE 196 17 527 A1 bekannt.Such open-end spinning devices are known for example from DE 196 17 527 A1.
Bei dieser Spinnvorrichtung weist ein schwenkbar gelagertes Deckelelement eine Ringnut zum Einlegen eines Lippendichtelementes sowie eine in Richtung Rotorgehäuse offene Aufnahme mit konischen Anlageflächen auf. In dieser Aufnahme ist lösbar ein Kanalplattenadapter festgelegt. Die winkelgenaue Einbaulage des Kanalplattenadapters wird mittels einer aus einem zentrierstift und einer bogenförmigen Nut bestehenden Positioniereinrichtung bewirkt, wobei über eine Kontrolleinrichtung das Einhalten der vorschriftsmäßigen Winkellage des Kanalplattenadapters in der Faserkanalplatte überwacht werden kann. Im eingebauten Zustand liegt der mittels des Zentrierstiftes winkelgenau ausgerichtete Kanalplattenadapter mit seiner konischen Anlagefläche an der entsprechend geformten Anlagefläche der Aufnahme an und wird dabei über gemeinsam wirkende form- und kraftschlüssige Befestigungsmittel mit einer in axialer Richtung wirkenden Haltekraft beaufschlagt.In this spinning device, a pivotably mounted cover element has an annular groove for inserting a lip sealing element and a receptacle with conical contact surfaces that is open in the direction of the rotor housing. A duct plate adapter is detachably fixed in this receptacle. The angularly precise installation position of the channel plate adapter is effected by means of a positioning device consisting of a centering pin and an arcuate groove, wherein the compliance with the correct angular position of the channel plate adapter in the fiber channel plate can be monitored via a control device. In the installed state, the conical contact surface of the channel plate adapter, which is aligned by means of the centering pin with its conical contact surface, lies against the correspondingly shaped contact surface of the receptacle and is subjected to a holding force acting in the axial direction via jointly acting positive and non-positive fastening means.
Bei dieser bekannten Vorrichtung ist die Art der Befestigung nachteilig.

Bajonettverschluß ausgebildete und mit der Magnetkupplung zusammenwirkende formschlüssige Befestigungsmittel ggf. unter Verwendung von Spezialwerkzeug gelöst werden.In this known device, the type of attachment is disadvantageous. To replace the duct plate adapter, you must always use e.g. The magnetic coupling used as a non-positive fastening means, the form-fitting fastening means designed as a threaded connection or bayonet lock and interacting with the magnetic coupling may be released using a special tool.
Ausgehend vom vorstehend beschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine vereinfachte und damit verbesserte Befestigung für Kanalplattenadapter zu schaffen.Starting from the prior art described above, the invention has for its object to provide a simplified and thus improved attachment for channel plate adapter.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.According to the invention, this object is achieved by a device having the characterizing features of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Ausbildung des kraftschlüssigen Befestigungsmittels als Magnetkupplung führt zu einer einfachen, im Bedarfsfall leicht und schnell lösbaren, während des Betriebes bzw. des Zusammenbaus jedoch sehr sicheren und exakten Fixierung des Kanalplattenadapters.The inventive design of the non-positive fastening means as a magnetic coupling leads to a simple, easily and quickly detachable if necessary, but very safe and exact fixation of the channel plate adapter during operation or assembly.
In bevorzugter Ausführungsform besteht die Magnetkupplung aus mindestens einem an der Faserkanalplatte oder dem Kanalplattenadapter festgelegten oder eingelassenen Permanentmagneten sowie einem damit zum Kraftschluß in axialer Richtung zusammenwirkenden ferromagnetischen, vorteilhaft als Scheibe ausgebildeten Bauteil, das am jeweils anderen Teil angeordnet und bevorzugt als Scheibe ausgebildet ist. vorzugsweise sind zwei symmetrisch angeordnete, scheibenförmige Permanentmagnete oder vorteilhaft auch ein zentrisch angeordneter Ringmagnet in der Faserkanalplatte oder einem mit der Faserkanalplatte verbundenen Bauelement fest verankert. Die zugehörigen ferromagnetischen Bauteile, zum Beispiel ein Stahlring oder zwei entsprechend symmetrisch angeordnete Stahlscheiben, sind dabei bevorzugt so im Kanalplattenadapter positioniert, daß sich im Einbauzustand die Permanentmagnete und die ferromagnetischen Bauteile unter Wahrung eines geringen Luftspaltes gegenüberstehen. Dieser Luftspalt gewährleistet eine paßgenaue axiale Einbaulage des Kanalplattenadapters, da dadurch sichergestellt ist, daß der Kanalplattenadapter stets im Bereich seiner konischen Anlagefläche aufliegt.In a preferred embodiment, the magnetic coupling consists of at least one permanent magnet fixed or embedded in the fiber channel plate or the channel plate adapter, and a ferromagnetic component which cooperates with it in the axial direction and is advantageously designed as a disk, which is arranged on the other part and is preferably designed as a disk. preferably two symmetrically arranged, disk-shaped permanent magnets or advantageously also a centrally arranged ring magnet are firmly anchored in the fiber channel plate or a component connected to the fiber channel plate. The associated ferromagnetic components, for example a Steel ring or two correspondingly symmetrically arranged steel disks are preferably positioned in the channel plate adapter so that the permanent magnets and the ferromagnetic components face each other while maintaining a small air gap. This air gap ensures a precisely fitting axial installation position of the channel plate adapter, since this ensures that the channel plate adapter always lies in the area of its conical contact surface.
Eine zwischen der Faserkanalplatte und dem Kanalplattenadapter angeordnete Positioniereinrichtung gewährleistet in einer weiteren vorteilhaften Ausgestaltung eine erforderliche winkelgenaue Einbaulage des Kanalplattenadapters. Von Vorteil ist auch die Verwendung eines Auswerfers für den Kanalplattenadapter.In a further advantageous embodiment, a positioning device arranged between the fiber channel plate and the channel plate adapter ensures that the channel plate adapter is required to be installed at an exact angle. The use of an ejector for the duct plate adapter is also advantageous.
Der Erfindungsgegenstand vereinigt in vorteilhafter Weise neben einer kostengünstigen Fertigung eine einfache und leichte Handhabung mit hoher Funktionssicherheit und einer sicheren und exakten Fixierung des Kanalplattenadapters in der Aufnahme der Faserkanalplatte. Mit der erfindungsgemäßen Ausbildung eines rein kraftschlüssigen, lösbaren Befestigungsmittels wird das herrschende Vorurteil, daß eine rein kraftschlüssige Befestigung für diesen Anwendungszweck keine ausreichende Betriebssicherheit bietet und das zu bekannter Kombination von kraftschlüssiger und formschlüssiger Befestigung führte, überwunden.In addition to cost-effective production, the subject of the invention advantageously combines simple and easy handling with high functional reliability and secure and exact fixation of the channel plate adapter in the receptacle of the fiber channel plate. With the design according to the invention of a purely non-positive, releasable fastening means, the prevailing prejudice that purely non-positive fastening for this purpose of use does not offer sufficient operational safety and that led to a known combination of non-positive and positive fastening.

Die in Fig. 1 in einer Teilansicht dargestellte Offenend-Spinnvorrichtung 1 weist, wie bekannt, ein Rotorgehäuse 2 auf, in dem ein Spinnrotor 3 mit hoher Drehzahl umläuft. Das nach vorne offene Rotorgehäuse 2 wird während des Betriebes nach vorne durch eine Faserkanalplatte 4 eines Deckelelementes 5 verschlossen. Die Faserkanalplatte 4 ist dabei als separates Bauteil am Deckelelement 5 befestigt. Sie kann auch direkt in das Deckelelement 5 integriert sein.As is known, the open-end spinning device 1 shown in a partial view in FIG. 1 has a rotor housing 2 in which a spinning rotor 3 rotates at high speed. The rotor housing 2, which is open at the front, is closed at the front during operation by a fiber channel plate 4 of a cover element 5. The fiber channel plate 4 is attached to the cover element 5 as a separate component. It can also be integrated directly into the cover element 5.
Die Faserkanalplatte 4 weist einen ringförmigen Ansatz für ein Lippendichtelement 6 sowie eine in Richtung des Rotorgehäuses 2 hin offene Aufnahme 7 auf. Die seitliche Anlagefläche 8 der Aufnahme 7 ist dabei nach Art eines Konus ausgebildet.The fiber channel plate 4 has an annular extension for a lip sealing element 6 and a receptacle 7 that is open in the direction of the rotor housing 2. The lateral contact surface 8 of the receptacle 7 is designed in the manner of a cone.
In der Aufnahme 7 ist ein Kanalplattenadapter 10 mit seinem Lagerkörper 9 winkelgenau ausrichtbar und leicht lösbar festgelegt. Die Befestigung erfolgt mittels einer Magnetkupplung 15. Der Kanalplattenadapter 10 weist eine zentrale Bohrung für eine Fadenabzugsdüse 11 sowie den auch in Fig. 3 dargestellten Mündungsbereich eines Faserleitkanales 12 auf. In Fadenabzugsrichtung schließt sich an die Fadenabzugsdüse 11 ein Fadenabzugsröhrchen 13 an.In the receptacle 7, a channel plate adapter 10 with its bearing body 9 can be aligned with precise angles and is easily detachable. The fastening takes place by means of a magnetic coupling 15. The channel plate adapter 10 has a central bore for a thread take-off nozzle 11 as well as the mouth region of a fiber guide channel 12 also shown in FIG. 3. In the thread take-off direction, a thread take-off tube 13 connects to the thread take-off nozzle 11.
Der Kanalplattenadapter 10 weist an seiner der Fadenabzugsdüse 11 gegenüberliegenden Seite ein Anschlußmittel 17 auf. Das Anschlußmittel 17 ist dabei als ferromagnetische, ringförmige Scheibe 18 ausgebildet, die fest in den zum Beispiel aus Aluminium oder Kunststoff gefertigten Kanalplattenadapter 10 eingepreßt ist.The channel plate adapter 10 has a connection means 17 on its side opposite the thread take-off nozzle 11. The connection means 17 is designed as a ferromagnetic, annular disk 18, which is firmly pressed into the channel plate adapter 10 made, for example, of aluminum or plastic.
Beim Einbau des Kanalplattenadapters 10 wird dieser mit seiner konischen Anlagefläche 19 an die entsprechend ausgebildete Anlagefläche 8 der Aufnahme 7 gezogen und dort fixiert. Ein an der Scheibe 18 befestigter und durch eine Öffnung 25 der Faserkanalplatte 4 teilweise nach außen ragender Auswerfer 24 ermöglicht ein einfaches Lösen des Kanalplattenadapters 10 von der Faserkanalplatte 4.When installing the duct plate adapter 10, its conical contact surface 19 is pulled onto the correspondingly designed contact surface 8 of the receptacle 7 and fixed there. An ejector 24 attached to the disk 18 and partially projecting outward through an opening 25 of the fiber channel plate 4 enables the channel plate adapter 10 to be easily detached from the fiber channel plate 4.
Die winkelgenaue Einbaulage des Kanalplattenadapters 10 ist anhand einer in Fig. 2 dargestellten Positioniereinrichtung 20, bestehend aus einem beispielsweise in den Adapter eingelassenen Zentrierstift 21 und einer in die Lagerscheibe 16 eingebrachten Bohrung 22, leicht erzielbar.The angularly precise installation position of the channel plate adapter 10 can be easily achieved using a positioning device 20 shown in FIG. 2, consisting of a centering pin 21, for example embedded in the adapter, and a bore 22 made in the bearing disk 16.
Zwei symmetrisch, wie aus Fig. 2 ersichtlich im Grund der Aufnahme 7 angeordnete, scheibenförmige Permanentmagnete 14,14' sind über eine in der Aufnahme 7 festgelegte Lagerscheibe 16 an der Faserkanalplatte 4 fest verankert, wobei die Lagerscheibe 16 die Magnetwirkung verstärkt. Das zugehörige ferromagnetische Bauteil, eine Stahlscheibe 18, ist dabei im Kanalplattenadapter 10 so positioniert, daß sich im Einbauzustand die Permanentmagnete 14,14' und das ferromagnetische Bauteil unter Wahrung eines geringen Luftspaltes 23 gegenüberstehen. Der Luftspalt 23 beträgt 0,1 bis 0,2 mm, so daß einerseits sichergestellt ist, daß der Kanalplattenadapter 10 stets mit der Anlagefläche 19 seines Lagerkörpers 9 an der entsprechenden Anlagefläche 8 der Aufnahme 7 der Faserkanalplatte 4 anliegt und andererseits eine Magnetkraft wirksam ist, die ausreichend groß ist, um den Kanalplattenadapter 10 während des Betriebes sowie beim Öffnen und Schließen des Deckelelementes 5 sicher in dieser Einbaulage zu halten. Der in Fig. 3 in der Rückansicht des Kanalplattenadapters 10 dargestellte Auswerfer 24 ist so angeordnet, daß er durch die Öffnung 25, deren Lage die Fig. 2 zeigt, aus der Oberfläche der Faserkanalplatte 4 hervorsteht. Das Lösen des Kanalplattenadapters 10 von der Faserkanalplatte 4 kann durch einfaches Überwinden des Kraftschlusses mittels manuellem Druck auf den fest mit dem Kanalplattenadapter 10 verbundenen Auswerfer 24 und Abheben des Adapters erfolgen.Two disc-shaped permanent magnets 14, 14 'arranged symmetrically in the base of the receptacle 7 as shown in FIG. 2 are firmly anchored to the fiber channel plate 4 via a bearing disk 16 fixed in the receptacle 7, the bearing disk 16 increasing the magnetic effect. The associated ferromagnetic component, a steel disk 18, is positioned in the channel plate adapter 10 such that the permanent magnets 14, 14 ′ and the ferromagnetic component face each other while maintaining a small air gap 23. The air gap 23 is 0.1 to 0.2 mm, so that on the one hand it is ensured that the channel plate adapter 10 always bears with the contact surface 19 of its bearing body 9 on the corresponding contact surface 8 of the receptacle 7 of the fiber channel plate 4 and on the other hand a magnetic force is effective, which is sufficiently large to hold the channel plate adapter 10 securely in this installed position during operation and when opening and closing the cover element 5. The ejector 24 shown in FIG. 3 in the rear view of the channel plate adapter 10 is arranged such that it projects through the opening 25, the position of which is shown in FIG. 2, from the surface of the fiber channel plate 4. The channel plate adapter 10 can be detached from the fiber channel plate 4 by simply overcoming the frictional connection manual pressure on the ejector 24 firmly connected to the channel plate adapter 10 and lifting the adapter.
Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele begrenzt. Die im Grund der Aufnahme 7 angeordneten Permanentmagnete 14,14' können anstatt in die Lagerscheibe 16 direkt in das Gehäuse der Faserkanalplatte 4 eingelassen werden. Es ist beispielsweise auch durchaus möglich, die Anordnung der Teile der Magnetkupplung 15 zu vertauschen und z.B. die Permanentmagnete 14,14' am Kanalplattenadapter 10 und die ferromagnetische Scheibe 18 an der Faserkanalplatte 4 anzuordnen.The invention is not limited to the exemplary embodiments shown. The permanent magnets 14, 14 ′ arranged in the base of the receptacle 7 can be inserted directly into the housing of the fiber channel plate 4 instead of in the bearing disk 16. For example, it is also entirely possible to interchange the arrangement of the parts of the magnetic coupling 15 and e.g. to arrange the permanent magnets 14, 14 'on the channel plate adapter 10 and the ferromagnetic disk 18 on the fiber channel plate 4.
Mit der erfindungsgemäßen Ausbildung läßt sich ein Auswechseln des Kanalplattenadapters 10 ohne Schraubbewegung bei Gewindeverbindungen oder Drehen eines Bajonettverschlusses durchführen, wodurch das Auswechseln einfacher und vor allem schneller erfolgt. Damit ist es auch nicht erforderlich, für die Erzeugung der Drehbewegung Spezialwerkzeug einzusetzen. Das Entfernen des Kanalplattenadapters 10 aus der Einbaulage " erfolgt lediglich durch Überwinden des Kraftschlusses.With the design according to the invention, the channel plate adapter 10 can be replaced without screwing in the case of threaded connections or turning a bayonet lock, as a result of which the exchange is easier and, above all, faster. It is therefore not necessary to use special tools to generate the rotary movement. The removal of the channel plate adapter 10 from the installation position "takes place only by overcoming the frictional connection.
Bei der Fertigung der erfindungsgemäßen Ausführung der Faserkanalplatte 4 samt Kanalplattenadapter 10 werden Bauteile bzw. Bearbeitungsvorgänge, insbesondere Gewindeteile oder die Gewindeherstellung, eingespart. Die Positioniereinrichtung 20 kann einfacher ausgeführt werden, da durch den Wegfall der Drehbewegung beim Lösen und Befestigen des Kanalplattenadapters 10 anstelle einer bogenförmigen Nut z.B. eine einfache Bohrung zur Aufnahme des in den Kanalplattenadapter 10 eingelassenen Zentrierstiftes ausreicht. Die erfindungsgemäße Faserkanalplatte 4 läßt sich somit kostengünstiger fertigen.In the manufacture of the embodiment of the fiber channel plate 4 together with the channel plate adapter 10, components or processing operations, in particular threaded parts or the thread production, are saved. The positioning device 20 can be made simpler, since by eliminating the rotary movement when loosening and fastening the channel plate adapter 10 instead of an arcuate groove, e.g. a simple hole for receiving the centering pin embedded in the channel plate adapter 10 is sufficient. The fiber channel plate 4 according to the invention can thus be manufactured more cost-effectively.
