Description

Die Erfindung betrifft eine Auflösewalze für eine Offenend-Spinnvorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to an opening roller for an open-end spinning device according to the preamble of claim 1.

Derartige Auflösewalzen für Offenend-Spinnvorrichtungen sind in verschiedenen Ausführungsformen bekannt und beispielsweise in der DE 197 12 880 A1 beschrieben.Such opening rollers for open-end spinning devices are known in various embodiments and for example described in DE 197 12 880 A1.

Durch die DE 40 36 017 A1 ist des weiteren eine Auflösewalze bekannt, deren Garniturring direkt auf dem Außenläufer eines Elektroantrieb angeordnet ist.
Das heißt, auf dem rotierbar gelagerten Außenläufer eines Auflösewalzenantriebes ist mittels eines sogenannten Spannsatzes ein Garniturring festgelegt.
From DE 40 36 017 A1, an opening roller is also known, the clothing ring of which is arranged directly on the outer rotor of an electric drive.
This means that a clothing ring is fixed on the rotatably mounted outer rotor of an opening roller drive by means of a so-called clamping set.

Ein solcher, im Maschinenbau durchaus bewährter Spannsatz ermöglicht zwar ein sicheres und bei Bedarf lösbares Festlegen eines Garniturringes auf einem frei rotierbar gelagerten Bauteil, das heißt, auf einem Bauteil, das während der Montage des Garniturringes nicht gegen Rotation gesichert werden kann, jedoch stellt ein solcher Spannsatz ein relativ aufwendiges und kostspieliges Konstruktionselement dar.Such a clamping set, which has been tried and tested in mechanical engineering allows a secure and if necessary releasable setting of a clothing ring on a freely rotatable one Component, that is, on a component during assembly the set ring cannot be secured against rotation, however, such a clamping set is relatively expensive and expensive construction element.

Außerdem gestaltet sich beim Einsatz eines Spannsatzes das Wechseln eines Garniturringes verhältnismäßig mühsam und zeitaufwendig, da in einem solchen Fall zunächst mittels eines entsprechenden Werkzeuges die einzelnen Spannschrauben des Spannsatzes gelöst werden müssen, die nach dem Einbau eines neuen Garniturringes dann wieder erneut angezogen werden müssen.In addition, this is the case when using a clamping set Changing a set ring is relatively tedious and time-consuming, because in such a case, initially using a appropriate tool the individual clamping screws of the Clamping set must be solved after installing a new rings are then tightened again have to.

Des weiteren sind durch die DE-OS 27 52 591 Auflösewalzen für Offenend-Spinnvorrichtungen bekannt, bei denen der Garniturring jeweils mittels einer drehmomentfreien Schnellspannvorrichtung leicht lösbar an einem Grundkörper der Auflösewalze festgelegt ist.
Das heißt, zwischen ein Spannelement, das den Garniturring in seiner Einbaulage sowohl axial als auch radial fixiert und dem Grundkörper sind Federelemente eingeschaltet, die das Spannelement und damit den Garniturring kraftschlüssig am Grundkörper der Auflöswalze festlegen sollen.
Die bekannte Auflösewalze konnte sich in der Praxis allerdings nicht durchsetzen, da die von den Federelementen aufgebrachten Haltekräfte nicht ausreichten, um unter allen Bedingungen eine weitestgehend schlupffreie Festlegung des Garniturringes auf dem Grundkörper der Auflösewalze zu gewährleisten.
Furthermore, from DE-OS 27 52 591 opening rollers for open-end spinning devices are known, in which the clothing ring is in each case easily detachably fixed to a base body of the opening roller by means of a torque-free quick clamping device.
That is, between a tensioning element that fixes the clothing ring in its installed position both axially and radially and the base body, spring elements are switched on, which are intended to fix the tensioning element and thus the clothing ring non-positively on the base body of the opening roller.
In practice, however, the known opening roller could not prevail, since the holding forces applied by the spring elements were not sufficient to ensure a largely slip-free fixing of the clothing ring on the base body of the opening roller under all conditions.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Auflösewalze zu schaffen, bei der der Garniturring problemlos und schnell auf einem frei rotierbar gelagerten Bauteil der Auflösewalze festlegbar ist.Based on the aforementioned prior art, the Invention based on the object of creating an opening roller in which the clothing ring easily and quickly on a free rotatably mounted component of the opening roller can be fixed.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved by a device solved, as described in claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Dependent claims.

Die erfindungsgemäße, drehmomentfreie Schnellspanneinrichtung hat insbesondere den Vorteil, daß sie ein problemloses Auswechseln eines Garniturringes auch dann ermöglicht, wenn das den Garniturring aufnehmende Bauteil frei rotierbar gelagert, das heißt, nicht gegen Rotation festgelegt werden kann.
Die Schnellspannvorrichtung verfügt dabei über zwei Exzenterklemmen, die ein Federelement, vorzugsweise eine Tellerfeder, beaufschlagen.
Über die Tellerfeder, die sich an einer Bordscheibe der Auflösewalze abstützt, wird eine axiale Kraftkomponente auf die Bordscheibe übertragen, die sicherstellt, daß der Garniturring zuverlässig zwischen der Bordscheibe und einem ringförmigen Ansatz am Außenläufer des Auflösewalzenantriebes fixiert wird.
Die erfindungsgemäße Schnellspanneinrichtung stellt außerdem ein sehr kostengünstiges und sicheres Befestigungsmittel dar, das ohne daß der Einsatz irgendeines Werkzeuges notwendig wird, eingesetzt werden kann.
The torque-free quick release device according to the invention has the particular advantage that it enables problem-free replacement of a clothing ring even if the component receiving the clothing ring is freely rotatable, that is to say cannot be fixed against rotation.
The quick release device has two eccentric clamps which act on a spring element, preferably a plate spring.
Via the plate spring, which is supported on a flanged wheel of the opening roller, an axial force component is transmitted to the flanged wheel, which ensures that the clothing ring is reliably fixed between the flanged wheel and an annular shoulder on the outer rotor of the opening roller drive.
The quick release device according to the invention also represents a very inexpensive and safe fastening means that can be used without the use of any tools.

Besonders vorteilhaft ist eine solche drehmomentfreie Schnellspanneinrichtung zum Beispiel einsetzbar, wenn, wie im Anspruch 2 dargelegt, als Auflösewalzenantrieb ein sogenannter Außenläufer zum Einsatz kommt. Das heißt, wenn der Garniturring direkt auf dem als Außenläufer ausgebildeten Rotor eines Auflösewalzenantriebes festgelegt werden soll und der frei drehbar gelagerte Rotor dabei nicht fixierbar ist.Such a torque-free one is particularly advantageous Quick release device can be used, for example, if, as in Claim 2 set out as a so-called opening roller drive Outrunner is used. That is, if the Set ring directly on the outside runner Rotor of an opening roller drive is to be determined and the freely rotatable rotor cannot be fixed.

Vorzugsweise weisen die Exzenterklemmen dabei, wie im Anspruch 3 dargelegt, jeweils eine manuell bedienbare Betätigungslasche sowie wenigstens einen exzentrisch gelagerten Klemmkörper auf.
Derartig ausgebildete Exzenterklemmen können, wie vorstehend bereits angedeutet, ohne den Einsatz eines speziellen Werkzeuges bedient werden und üben aufgrund ihrer Übersetzung in ihrer Arbeitsposition einen solchen Druck auf die Tellerfeder aus, daß diese mechanisch verformt wird.
Preferably, as stated in claim 3, the eccentric clamps each have a manually operated actuating tab and at least one eccentrically mounted clamping body.
Eccentric clamps designed in this way can, as already indicated above, be operated without the use of a special tool and, due to their translation in their working position, exert such pressure on the plate spring that it is mechanically deformed.

Wie im Anspruch 4 ausgeführt, sind die Exzenterklemmen über eine Schwenkachse mit einem Bolzen verbunden, der seinerseits über einen Bajonettverschluß am Außenläufer des Elektroantriebes festlegbar ist.
Ein solcher Bajonettverschluß stellt, insbesondere, wenn er die im Anspruch 5 oder die im Anspruch 6 beschriebene Ausführungsform aufweist, ein einfaches, während des Betriebes jedoch zuverlässiges Befestigungsmittel dar, das im Bedarfsfall jederzeit problemlos gelöst werden kann.
As stated in claim 4, the eccentric clamps are connected via a pivot axis to a bolt, which in turn can be fixed on the external rotor of the electric drive via a bayonet lock.
Such a bayonet lock, especially if it has the embodiment described in claim 5 or in claim 6, is a simple, but reliable during operation fastener that can be easily solved if necessary.

Die an den Exzenterklemmen angeordneten Betätigungslaschen liegen im Betriebszustand der Auflösewalze geschützt in einer zentralen Aussparung der Bordscheibe (Anspruch 7).
Eine solche Ausbildung der Exzenterklemmen gewährleistet nicht nur einen optimalen Schutz des Bedienpersonals, insbesondere, wenn die zentrale Aussparung, was im vorliegenden Ausführungsbeispiel nicht dargestellt ist, mit einer Abdeckkappe verschlossen wird, sondern die Betätigungslaschen der Exzenterklemmen sind im Bedarfsfall auch problemlos zugängig.
Das heißt, zum Lösen der Schnellspanneinrichtung müssen lediglich die Betätigungslaschen aufgeklappt und der mittels Bajonettverschluß fixierte Bolzen der Schnellspanneinrichtung um beispielsweise 45° im Gegenuhrzeigersinn gedreht werden.
When the opening roller is in the operating state, the actuating tabs arranged on the eccentric clamps are protected in a central recess in the flanged disc (claim 7).
Such a design of the eccentric clamps not only ensures optimal protection of the operating personnel, in particular if the central recess, which is not shown in the present exemplary embodiment, is closed with a cover cap, but the actuating tabs of the eccentric clamps are also easily accessible if necessary.
This means that to release the quick release device, only the actuating tabs have to be opened and the bolt of the quick release device fixed by means of a bayonet lock has to be rotated counterclockwise, for example by 45 °.

Weitere Einzelheiten der Erfindung sind einem nachfolgend anhand der Zeichnungen erläuterten Ausführungsbeispiel entnehmbar.Further details of the invention are as follows exemplary embodiment explained with reference to the drawings removable.

Die Figur 1 zeigt einen Auflösewalzenantrieb 4, der als sogenannter Außenläufer ausgebildet ist. Das heißt, der Stator 9, der über entsprechende Befestigungsmittel, beispielsweise Schraubenbolzen 10, an ein Auflösewalzengehäuse 11 angeschlossen ist, wird von einem Rotor umfaßt, der in einem solchen Fall als Außenläufer 4 bezeichnet wird.
Die Statorwicklung 12 des Auflösewalzenantriebes 4 ist dabei über eine Energieleitung 13 mit einer (nicht dargestellten) Energiequelle verbunden. Auf dem Außenumfang 27 des, wie vorstehend angedeutet, als Außenläufer 3 ausgebildeten Rotors des elektrischen Antriebes 4 ist außerdem, auswechselbar, ein Garniturring 2 einer Auflösewalze 1 festgelegt.
Das heißt, zwischen einer Bordscheibe 5 und einem ringförmigen Ansatz 6 des Außenläufers 3 ist, durch die Bordscheibe 5 in axialer Richtung beaufschlagt, ein Garniturring 2 fixiert.
Die Bordscheibe 5 ist dabei über eine drehmomentfreie Schnellspanneinrichtung 7, die auf eine Tellerfeder 8 wirkt, an den Außenläufer 3 angeschlossen.
FIG. 1 shows an opening roller drive 4, which is designed as a so-called external rotor. That is to say, the stator 9, which is connected to an opening roller housing 11 via corresponding fastening means, for example screw bolts 10, is encompassed by a rotor, which in this case is referred to as the external rotor 4.
The stator winding 12 of the opening roller drive 4 is connected via an energy line 13 to an energy source (not shown). On the outer circumference 27 of the rotor of the electric drive 4 designed as an external rotor 3, as indicated above, a clothing ring 2 of an opening roller 1 is also interchangeably fixed.
This means that between a flanged wheel 5 and an annular shoulder 6 of the external rotor 3, a clothing ring 2 is fixed by the flanged wheel 5 in the axial direction.
The flanged wheel 5 is connected to the external rotor 3 via a torque-free quick-action clamping device 7, which acts on a plate spring 8.

Bordscheibe 5 und Garniturring 2 können dabei auch als Montageeinheit ausgebildet sein. Das bedeutet, der Zentrieransatz 28 der Bordscheibe 5 und der Innendurchmesser 29 des Garniturringes 2 sind so aufeinander abgestimmt, daß sie miteinander eine festsitzende Passung bilden, die gewährleistet, daß diese Bauteile gemeinsam ein- und ausgebaut werden können. Der Garniturring 2 und die Bordscheibe 5 können dabei bereits in einem vorgeschalteten Arbeitsgang miteinander verbunden werden.Flanged wheel 5 and trim ring 2 can also be used as Assembly unit be formed. That means the Centering shoulder 28 of the flanged wheel 5 and the inner diameter 29 of the clothing ring 2 are coordinated so that they form a tight fit with each other, the ensures that these components are installed and removed together can be. The trim ring 2 and the flanged wheel 5 can with each other in an upstream operation get connected.

Wie insbesondere aus den Figuren 2 bis 4 ersichtlich, besteht die drehmomentfreie Schnellspanneinrichtung 7 beispielsweise aus einem Bolzen 14, der radiale Ansätze 15 für einen Bajonettverschluß 16 sowie eine Schwenkachse 17 aufweist.
Am Bolzen 14 sind zwei Betätigungslaschen 18 schwenkbar gelagert.
Die Betätigungslaschen 18 sind dabei über exzentrisch gelagerte Bohrungen in den Klemmkörpern 19 sowie die Schwenkachse 17 mit dem Bolzen 14 verbunden.
Der Bolzen 14 ist seinerseits mit seinem zylindrischen Körper 20 in einer entsprechenden Bohrung 21 eines kragenförmigen Ansatzes 22 des Außenläufers 3, begrenzt drehbar, gelagert.
Das heißt, in den kragenartigen Ansatz 22 sind entweder, wie insbesondere aus Fig.5 ersichlich, axiale Nuten 23 sowie schraubenförmige Nuten 24 eingelassen, in denen die radialen Ansätze 15 des Bolzens 14 geführt sind, oder der Bolzen 14 weist, wie in Fig.6 angedeutet, seinerseits radiale und schraubenförmige Nuten 23' bzw. 24' auf, in die dann entsprechende radiale Ansätze 15' des kragenartigen Ansatzes 22 einfassen.
Das heißt, die Nuten 23, 24 bzw. 23', 24' bilden zusammen mit den radialen Ansätzen 15 bzw. 15' jeweils einen Bajonettverschluß 16 der Bestandteil der drehmomentfreien Schnellspanneinrichtung 7 ist.
As can be seen in particular from FIGS. 2 to 4, the torque-free quick-release device 7 consists, for example, of a bolt 14 which has radial projections 15 for a bayonet lock 16 and a pivot axis 17.
Two actuating tabs 18 are pivotally mounted on the bolt 14.
The actuating tabs 18 are connected to the bolt 14 via eccentrically mounted bores in the clamping bodies 19 and the pivot axis 17.
The bolt 14 is in turn mounted with its cylindrical body 20 in a corresponding bore 21 of a collar-shaped extension 22 of the external rotor 3, with limited rotation.
This means that, as can be seen in particular in FIG. 5, axial grooves 23 and helical grooves 24, in which the radial projections 15 of the bolt 14 are guided, or the bolt 14, as shown in FIG. 6 indicated, in turn radial and helical grooves 23 'and 24', in which then surround corresponding radial lugs 15 'of the collar-like extension 22.
That is, the grooves 23, 24 and 23 ', 24' together with the radial lugs 15 and 15 'each form a bayonet lock 16 which is part of the torque-free quick release device 7.

Funktion der Einrichtung:Function of the facility:

Im Betriebszustand der Auflösewalze, der beispielsweise in den Figuren 1, 2 und 3 angedeutet ist, sind die Betätigungslaschen 18 nach außen verschwenkt und liegen dabei geschützt in einer zentralen Aufnahmebohrung 25 der Bordscheibe 5. Diese zentrale Aufnahmebohrung 25 kann dabei zusätzlich durch eine (nicht dargestellte) Schutzkappe verschlossen sein.
In dieser Lage beaufschlagen die exzentrisch gelagerten Klemmkörper 19 der Exzenterklemmen 26 die Tellerfeder 8, die dadurch ihrerseits mit einer radialen Kraftkomponente auf die Bordscheibe 5 wirkt. Unter der Einwirkung dieser axialen Kraftkomponente wird der Garniturring 2 gegen den ringförmigen Anschlag 6 am Außenläufer 3 des Elektroantriebes 4 gedrückt und dabei kraftschlüssig fixiert.
In the operating state of the opening roller, which is indicated, for example, in FIGS. 1, 2 and 3, the actuating tabs 18 are pivoted outward and are protected in a central receiving bore 25 of the flanged disc 5. This central receiving bore 25 can additionally be provided by a (not shown) ) Protective cap must be closed.
In this position, the eccentrically mounted clamping bodies 19 of the eccentric clamps 26 act on the plate spring 8, which in turn acts on the flanged disc 5 with a radial force component. Under the action of this axial force component, the clothing ring 2 is pressed against the annular stop 6 on the outer rotor 3 of the electric drive 4 and thereby fixed in a force-fitting manner.

Zum Wechseln des Garniturringes 2 wird zunächst der Elektroantrieb 4 gestoppt, das heißt, der Stator 12 wird stromlos geschaltet.To change the ring set 2, first the Electric drive 4 stopped, that is, the stator 12 switched off.

Sobald die Auflösewalze 1 in den Stillstand ausgelaufen ist, werden die Betätigungslaschen 18 der Exzenterklemmen 26 der Schnellspanneinrichtung 7 in die in Figur 4 angedeutete Stellung verschwenkt, in der die exzentrisch gelagerten Klemmkörper 19 der Exzenterklemmen 26 außer Anlage mit der Tellerfeder 8 sind.
Die Exzenterklemmen 26 werden anschließend über die Betätigungslaschen 18, zum Beispiel im Gegenuhrzeigersinn, so weit gedreht, bis die radialen Ansätze 15 am Bolzen 14 der Schnellspanneinrichtung 7 mit den axialen Nuten 23 im kragenförmigen Ansatz 22 des Außenläufers 3 korrespondieren.
Die Schnellspanneinrichtung 7 kann dann aus der Bohrung 21 des kragenförmigen Ansatzes 22 des Außenläufers 3 gezogen und die Bordscheibe 5 sowie der Garniturring 2 ausgebaut werden.
Zur Durchführung der vorbeschriebenen Tätigkeiten ist dabei keinerlei Einsatz von Werkzeug notwendig.
As soon as the opening roller 1 has come to a standstill, the actuating tabs 18 of the eccentric clamps 26 of the quick release device 7 are pivoted into the position indicated in FIG. 4, in which the eccentrically mounted clamping bodies 19 of the eccentric clamps 26 are out of contact with the plate spring 8.
The eccentric clamps 26 are then rotated via the actuating tabs 18, for example counterclockwise, until the radial projections 15 on the bolt 14 of the quick-action clamping device 7 correspond to the axial grooves 23 in the collar-shaped extension 22 of the external rotor 3.
The quick release device 7 can then be pulled out of the bore 21 of the collar-shaped extension 22 of the external rotor 3 and the flanged wheel 5 and the clothing ring 2 can be removed.
No tools are required to carry out the activities described above.

Der Wiedereinbau eines neuen Garniturringes 2 erfolgt in umgekehrter Reihenfolge.
Das heißt, nach dem Aufschieben eines neuen Garniturringes 2 auf den Außenumfang 27 des Außenläufer 3 des Elektroantriebes 4 wird die Bordscheibe 5 positioniert und die Tellerfeder 8 in die zentrale Aussparung 25 der Bordscheibe 5 eingelegt. Anschließend wird die Schnellspanneinrichtung 7 montiert.
Das bedeutet, der zylindrische Körper 20 des Bolzens 14 mit seinen radialen Ansätzen 15 wird so in die Bohrung 21 des kragenförmigen Ansatzes 22 des Außenläufers 3 eingeführt, daß die Ansätze 15 in die axialen Nuten 23 gleiten. Der Bolzen 14 wird dann mittels der Betätigungslaschen 18 im Uhrzeigersinn gedreht, was zu einer Fixierung der Schnellspanneinrichtung 7 am Außenläufer 3 des Elektroantriebes 4 führt.
Im Anschluß daran werden die Betätigungslaschen 18 um die Schwenkachse 17 nach außen geschwenkt. Bei dieser Verschwenkung beaufschlagen die exzentrisch gelagerten Klemmkörper 19 der Exzenterklemmen 26 die Tellerfeder 8, die ihrerseits die Bordscheibe 5 gegen den Garniturring 2 drückt und diesen dabei kraftschlüssig arretiert.
Reinstalling a new clothing ring 2 is done in reverse order.
That is, after a new clothing ring 2 has been pushed onto the outer circumference 27 of the outer rotor 3 of the electric drive 4, the flanged disc 5 is positioned and the plate spring 8 is inserted into the central recess 25 of the flanged disc 5. Then the quick release device 7 is mounted.
This means that the cylindrical body 20 of the bolt 14 with its radial projections 15 is inserted into the bore 21 of the collar-shaped projection 22 of the external rotor 3 in such a way that the projections 15 slide into the axial grooves 23. The bolt 14 is then rotated clockwise by means of the actuating tabs 18, which leads to a fixation of the quick release device 7 on the external rotor 3 of the electric drive 4.
Subsequently, the actuating tabs 18 are pivoted outward about the pivot axis 17. During this pivoting, the eccentrically mounted clamping bodies 19 of the eccentric clamps 26 act on the plate spring 8, which in turn presses the flanged disc 5 against the clothing ring 2 and thereby locks it in a force-locking manner.

Die vorbeschriebene, drehmomentlose Schnellspanneinrichtung 7 ermöglicht nicht nur ein problemloses und schnelles Austauschen von Garniturringen 2, sondern stellt auch eine sehr kostengünstige und sichere Befestigungseinrichtung dar.The torque-free quick release device 7 described above not only enables easy and quick Replacing clothing rings 2, but also provides one very inexpensive and safe fastening device.

Die Erfindung ist nicht auf das in den Zeichnungen beschriebene Ausführungsbeispiel beschränkt.
Es sind durchaus Modifikationen einzelner Bauteile möglich, ohne daß dadurch der allgemeine Erfindungsgedanke verlassen wird.
The invention is not restricted to the exemplary embodiment described in the drawings.
Modifications of individual components are possible without departing from the general idea of the invention.

Es ist beispielsweise möglich, daß die Exzenterklemmen 26 nicht, wie im Ausführungsbeispiel dargelegt, jeweils zwei Klemmkörper 19 aufweisen, sondern daß jeweils pro Exzenterklemme 26 nur ein Klemmkörper 19 zum Beaufschlagen der Tellerfeder 8 vorgesehen ist.For example, it is possible for the eccentric clamps 26 not two, as explained in the exemplary embodiment Have clamp body 19, but that each Eccentric clamp 26 only one clamp body 19 for loading the Disc spring 8 is provided.

Des weiteren ist es zum Beispiel denkbar, anstelle einer Tellerfeder 8 ein vergleichbares Federelement, z.B eine Schraubenfeder oder dgl., zum Einsatz kommt.It is also conceivable, for example, instead of one Belleville spring 8 a comparable spring element, e.g. a Coil spring or the like, is used.
