Description
Die Erfindung betrifft eine Offenend-Rotorspinnvorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to an open-end rotor spinning device according to the preamble of claim 1.
Derartige Offenend-Rotorspinnvorrichtungen sind durch verschiedene Veröffentlichungen bekannt.Such open-end rotor spinning devices are through various publications known.
Die DE 36 36 182 C2 beschreibt beispielsweise Rotorspinnvorrichtungen, die mit ihren Spinnboxgehäusen am Maschinengestell einer OE-Spinnmaschine festgelegt sind. Jedes Spinnboxgehäuse weist ein besaugbares Rotorgehäuse auf, in dem die Rotortasse eines auf Stützscheiben gelagerten Spinnrotors umläuft. Das nach vorne an sich offene Rotorgehäuse ist während des Spinnprozesses durch ein Deckelelement verschlossen.DE 36 36 182 C2 describes, for example Rotor spinning devices with their spin box housings on Machine frame of an OE spinning machine are set. Each spin box housing has an extractable rotor housing, in which the rotor cup is mounted on support disks Spinning rotor rotates. The rotor housing, which is open to the front is during the spinning process by a cover element locked.
Bei dieser bekannten Rotorspinnvorrichtung weist das schwenkbar gelagerte Deckelelement außerdem eine Faserbandauflöseeinrichtung auf, die, wie üblich, im wesentlichen aus einem Faserbandeinzugszylinder, einer in einem Auflösewalzengehäuse rotierenden Auflösewalze sowie einem sich zwischen der Auflösewalze und dem Spinnrotor erstreckenden, einteiligen Faserleitkanal besteht.In this known rotor spinning device, this has a pivotable design stored lid element also a Sliver opening device, which, as usual, in essentially from a sliver feed cylinder, one in one Opening roller housing rotating opening roller and one itself extending between the opening roller and the spinning rotor, one-piece fiber guide channel.
Zur Durchführung von, zum Beispiel, Wartungsarbeiten kann die Spinnbox geöffnet werden. In diesem Fall wird das Deckelelement entriegelt und um eine Schwenkachse nach unten geklappt, die im hinteren Spinnboxbereich liegt. Beim Verschwenken des Deckelelementes kommt dabei sowohl der Antriebswirtel der Auflösewalze als auch das endseitig des Faserbandeinzugszylinders angeordnete Schneckenrad außer Eingriff mit den zugehörigen Antriebsmitteln, das heißt, die rotierbaren Bauelemente der Faserbandauflöseeinrichtung laufen in den Stillstand aus. Gleichzeitig wird über ein Hebelgestänge das Abbremsen des Spinnrotors eingeleitet.For example, to carry out maintenance work Spin box can be opened. In this case the cover element unlocked and folded down about a pivot axis, which in the rear spinning box area. When swiveling the Cover element comes both the drive whorl Opening roller and the end of the Sliver feed cylinder arranged worm wheel except Engagement with the associated drive means, that is, the rotatable components of the sliver opening device run to a standstill. At the same time, a lever linkage braking of the spinning rotor initiated.
Nachteilig bei dieser Art von Spinnboxen ist vor allem die Einbaulage der Schwenkachse des Deckelelementes. Die relativ weit hinter der Rotortasse angeordnete Schwenkachse führt zu ungünstigen geometrischen Verhältnissen und damit zu gewissen Problemen insbesondere beim Einschwenken des die Faserleitkanalmündung aufweisenden Kanalplattenansatzes in die Öffnung der Rotortasse.The disadvantage of this type of spin boxes is above all that Installation position of the swivel axis of the cover element. The relative Swivel axis arranged far behind the rotor cup leads to unfavorable geometric conditions and thus certain Problems especially when swiveling the Fiber channel channel opening having channel plate approach in the Opening the rotor cup.
Der vorbeschriebene Nachteil konnte bei Offenend-Rotorspinnvorrichtungen, wie sie beispielsweise durch die DE 43 23 213 A1 oder die DE 43 04 088 A1 bekannt sind, vermieden werden.The disadvantage described above could Open-end rotor spinning devices, such as those used by DE 43 23 213 A1 or DE 43 04 088 A1 are known, be avoided.
Die DE 43 23 213 A1 beschreibt beispielsweise eine Rotorspinnvorrichtung, deren Deckelelement um eine orthogonal zur Rotorachse ausgerichtete, senkrecht unterhalb der Rotoröffnung angeordnete Schwenkachse drehbar gelagert ist. Die Schwenkachse, um die das Deckelelement gekippt werden kann, wird dabei vorzugsweise durch kurze Bolzen gebildet, die in nach vorne kragenden Auslegern der Spinnboxgehäusewandung angeordnet sind und die von am Deckelelement angeordneten, nach hinten weisenden Befestigungslaschen mit schlitzartigen Ausnehmungen überfaßt werden. Die Bolzen werden in diesen Ausnehmungen durch abschraubbare Sicherungsmittel arretiert.DE 43 23 213 A1 describes, for example Rotor spinning device, the cover element of which is orthogonal aligned to the rotor axis, perpendicularly below the Rotor opening arranged pivot axis is rotatably mounted. The pivot axis around which the cover element can be tilted is preferably formed by short bolts that in cantilevers of the spinning box housing wall are arranged and arranged on the cover element, after rear-facing fastening tabs with slit-like Recesses are covered. The bolts are in this Recesses locked by unscrewable securing devices.
Das heißt, das verschwenkbare Deckelelement kann nach Lösen der Sicherungsmittel als Ganzes abgenommen. Die Anordnung der Schwenkachse etwa senkrecht unter der Rotoröffnung führt zwar dazu, daß der beim Einschwenken des Kanalplattenansatzes zu berücksichtigende vertikale Versatz sehr gering ist und daher der Mündungsbereich des Faserleitkanales sehr nahe an die Faserrutschwand des Rotors herangelegt werden kann, was sich sehr positiv auf das Spinnergebnis auswirkt, nachteilig bei dieser bekannten Einrichtung ist allerdings, daß die im Bereich der Schwenkachse des Deckelelementes angeordneten Sicherungsmittel bei in die Textilmaschine eingebauten Spinnvorrichtungen kaum oder nur sehr schwer zugängig sind.This means that the pivotable cover element can be loosened after the Belay means removed as a whole. The arrangement of the Swivel axis leads approximately perpendicularly under the rotor opening to the fact that when swiveling the channel plate approach considering vertical offset is very small and therefore the mouth area of the fiber guide channel very close to the Fiber slide wall of the rotor can be applied to what is has a very positive effect on the spinning result, disadvantageous at this known device, however, is that in the area arranged the pivot axis of the cover element Securing means for built in the textile machine Spinning devices are hardly or only very difficult to access.
Die Rotorspinnvorrichtung gemäß DE 43 04 088 A1 beschreibt eine
Rotorspinnvorrichtung mit einem abnehmbaren Deckelelement, das
über eine gabelartige Aufnahme auf einer entsprechend
geformten, an der Spinnboxgehäusewandung festgelegten Lagerung
lösbar gehaltert ist.
Das heißt, das Deckelelement ist quer zur seiner Schwenkachse,
die im Bereich der maschinenlangen Antriebswelle für den
Faserbandeinzugszylinder liegt, von seiner Lagerung am
Spinnboxgehäuse abnehmbar, ohne daß vorher irgendwelche
Sicherungselemente oder dergleichen gelöst werden müssen.The rotor spinning device according to DE 43 04 088 A1 describes a rotor spinning device with a removable cover element, which is detachably supported via a fork-like receptacle on a correspondingly shaped bearing attached to the wall of the spinning box housing.
This means that the cover element can be removed transversely to its pivot axis, which is in the area of the machine-long drive shaft for the fiber ribbon feed cylinder, from its mounting on the spinning box housing without any securing elements or the like having to be released beforehand.
Bei einer solchen Ausführungsform ist allerdings die Gefahr, daß sich das aufgeklappte Deckelelement versehentlich von seiner Lagerung löst, nicht völlig auszuschließen.In such an embodiment, however, there is a risk that that the opened cover element accidentally its storage triggers, not to be completely excluded.
Ausgehend von Offenend-Rotorspinnvorrichtungen der vorbeschriebenen Gattung liegt der Erfindung die Aufgabe zugrunde, derartige Rotorspinnvorrichtungen zu verbessern.Starting from open-end rotor spinning devices of above described genus, the invention has the object based on improving such rotor spinning devices.
Diese Aufgabe wird erfindungsgemäß durch eine Offenend-Rotorspinnvorrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved by a Open-end rotor spinning device solved as in claim 1 is described.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Advantageous embodiments of the invention are the subject of Dependent claims.
Die erfindungsgemäße Anbindung des schwenkbar gelagerten Deckelelementes an das Spinnboxgehäuse mittels verschiebbar gelagerter, definiert ansteuerbare verriegelungsbolzen hat den Vorteil, daß einerseits eine sichere Arretierung des Deckelelementes am Spinnboxgehäuse sowohl während des Spinnprozesses als auch in geöffnetem Zustand gewährleistet ist und andererseits im Bedarfsfall, wenn zum Beispiel an den Aggregaten der in das Deckelelement integrierten Faserbandauflöseeinrichtung Einstell- oder Reinigungsarbeiten durchgeführt werden sollen, durch einfaches Abnehmen des Deckelelementes die Zugängigkeit der Spinnbox sowie des Deckelelementes erheblich verbessert werden kann. Nach Beendigung der Arbeiten kann das Deckelelement dann ebenso problemlos wieder eingebaut werden. Zum Ein- und Ausbau des Deckelelementes ist weder ein Werkzeug nötig, noch fallen dabei irgendwelche zeitaufwendigen Justierarbeiten an.The inventive connection of the pivoted Cover element to the spin box housing by means of sliding stored, controllable locking bolt has the Advantage that on the one hand a secure locking of the Cover element on the spin box housing both during the Spinning process is guaranteed as well as in the open state and on the other hand if necessary, for example to the Aggregates of the integrated in the cover element Sliver opening device Adjustment or cleaning work should be performed by simply removing the Cover element the accessibility of the spin box and the Cover element can be significantly improved. To The cover element can then also be completed can be easily reinstalled. To install and remove the Cover element is neither a tool necessary nor fall any time-consuming adjustment work.
In vorteilhafter Ausgestaltung verfügen die
Verriegelungsbolzen, wie im Anspruch 2 dargelegt, über
rotationssymmetrische Lageransätze, die im Einbauzustand des
Deckelelementes in entsprechenden Lagerschalen in den
Anschlußwangen des Spinnboxgehäuses positioniert sind.
Die in den Lagerschalen drehbar gelagerten Lageransätze der
Verriegelungsbolzen bilden dabei eine Schwenkachse, um die das
Deckelelement beim öffnen der Spinnbox schwenkbar gelagert ist.In an advantageous embodiment, the
Locking bolt as set out in
Vorzugsweise sind die Verriegelungsbolzen dabei, wie im
Anspruch 3 beschrieben, jeweils über ein Federelement permanent
beaufschlagt. Das heißt, die verriegelungsbolzen werden ständig
im Sinne "Verriegelungsbolzen ausfahren" beaufschlagt, so daß
auf einfache Weise sichergestellt ist, daß das Deckelelement
während der "normalen" Arbeitsgänge stets zuverlässig am
Spinnboxgehäuse befestigt ist. Preferably, the locking bolts are, as in
Wie im Anspruch 4 dargelegt, sind die beiden Verriegelungsbolzen über eine Getriebeanordnung, vorzugsweise bestehend aus gelenkbeweglich angeschlossenen Hebelgestängen, einem Anschlußmittel sowie einem Betätigungshebel miteinander gekoppelt. Die Verriegelungsbolzen können dadurch auf einfache Weise über einen gemeinsamen Betätigungshebel gleichmäßig angesteuert, das heißt, im Bedarfsfall aus ihren Lagerschalen in den Anschlußwangen des Spinnboxgehäuses zurückgezogen werden.As set out in claim 4, the two are Locking bolt via a gear arrangement, preferably consisting of articulated lever linkages, a connecting means and an operating lever with each other coupled. The locking bolts can be easily Way evenly over a common operating lever controlled, that is, from their bearing shells if necessary withdrawn in the connecting cheeks of the spin box housing become.
In bevorzugter Ausführungsform ist der Betätigungshebel dabei
so angeordnet, daß er nur bei geöffnetem Deckelelement zugängig
ist (Anspruch 5).
Das heißt, das Deckelelement kann nur in einem Betriebszustand
abgenommen werden, in dem sicher gewährleistet ist, daß die
während des Spinnbetriebes mit hoher Drehzahl rotierenden
Betriebsmittel (Spinnrotor, Auflösewalze) bereits stillgesetzt
sind.In a preferred embodiment, the actuating lever is arranged so that it is only accessible when the cover element is open (claim 5).
This means that the cover element can only be removed in an operating state in which it is reliably ensured that the equipment (spinning rotor, opening roller) rotating at high speed during the spinning operation is already shut down.
