Description

Die Erfindung betrifft eine Fadenhülse zur Klemmung auf einer Spindel, bzw. eine Spindel zur Aufnahme einer klemmend auf dieser aufgesteckten Hülse.The invention relates to a thread sleeve for clamping on a spindle, or a spindle for receiving a sleeve clamped on this.

In der Textilindustrie und insbesondere bei Feinspinnmaschinen, kommen derartige Hülsen mehrfach tagtäglich zur Anwendung. Bei einer herkömmlichen Hülse findet die einzige Zentrierung statt, indem das untere Hülsenende gegen den Konus der Spindel geklemmt wird. Meist sind ausserdem drei federbelastete, kalottenförmige Mitnehmer auf etwa 5/6 der Spindelhöhe am Spindelumfang vorgesehen. Diese Mitnehmer zentrieren die Hülse nicht, da die Federn herstellungsbedingte Abweichungen haben können. Bei den üblichen Spindeldrehzahlen unterhalb 20 000 UPM war diese Art von Klemmung zufriedenstellend. Der Trend ist aber eine Erhöhung der Drehzahl und dann können Probleme entstehen. So ist es bereits vorgekommen, dass kalottenförmige Mitnehmer bei höheren Drehzahlen aus leeren Spindeln, zentrifugalbedingt, herausgeflogen sind. Einerseits stellt dies eine Gefahr für das Personal dar, andererseits erhalten diese Spindeln eine Unwucht. Zusätzlich muss eine Wiederinstandstellung der betreffenden Spindeln erfolgen, was unter Umständen eine Stillsetzung der ganzen Ringspinnmaschine nach sich zieht. Des weiteren wird die Federkraft der Kalottenfedern durch die erhöhte Zentrifugalkraft geschmälert, sodass die Hülsen schlottern und nicht koaxial auf der Spindel gehalten werden können, was wiederum Unwuchtprobleme verursacht. Durch die inhärente Elastizität des Hülsenwerkstoffes weiten sich die am Spindelkonus anliegenden Hülsendurchmesser aus, sodass die Klemmwirkung nachlässt.Such sleeves are used several times a day in the textile industry and especially in fine spinning machines. In a conventional sleeve, the only centering takes place by clamping the lower sleeve end against the cone of the spindle. In addition, three spring-loaded, dome-shaped drivers are usually provided on the spindle circumference at approximately 5/6 of the spindle height. These drivers do not center the sleeve because the springs can have manufacturing-related deviations. At the usual spindle speeds below 20,000 rpm, this type of clamping was satisfactory. However, the trend is an increase in speed and then problems can arise. It has already happened that dome-shaped drivers have flown out of empty spindles at higher speeds due to centrifugal effects. On the one hand, this poses a danger to the personnel, on the other hand, these spindles are imbalanced. In addition, the spindles in question must be repaired, which in some circumstances may result in the entire ring spinning machine being shut down. Furthermore, the spring force of the spherical springs is reduced by the increased centrifugal force, so that the sleeves shake and cannot be held coaxially on the spindle, which in turn causes unbalance problems. Due to the inherent elasticity of the sleeve material, the sleeve diameter on the spindle cone expands, so that the clamping effect diminishes.

Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Fadenhülse bzw. eine Spindel für hohe Geschwindigkeiten zu schaffen, die eine Verbesserung der Befestigung der Hülse auf einer Spindel bei hohen Drehzahlen ermöglicht.It is therefore an object of the present invention to provide a thread sleeve or a spindle for high speeds, the one Enhances the mounting of the sleeve on a spindle at high speeds.

Diese Aufgabe wird durch die Merkmale der kennzeichnenden Teile der Ansprüche 1 bzw. 12 gelöst. Es wird dann bei Ausweitung des Hülsenaussendurchmessers die Klemmung immer stärker. Da ein Hülsenteil durch die Zentrifugalkraft bzw. Zentripetalkraft gegen einen Teil der Spindel gedrückt wird, bleibt die koaxiale Lage der Hülse erhalten. Die Hülse wird vorzugsweise in deren unterem und oberem Endbereich auf der Spindel geklemmt. Im unteren Hülsenendbereich liegt die Hülse an einen Zentrierrand an. Durch Lippenbildung im unteren Hülsenendbereich kann die Klemmkraft noch erhöht werden. Mit einem unterbrochenen Zentrierrand geht ein Selbstreinigungseffekt einher, da Flug- und lose Fasern automatisch weggeschleudert werden. Erfinderisch ist ebenfalls das Vorhandensein eines Schutzringes, der den unteren Hülsenklemmbereich, besonders beim Fallenlassen, schützt. Im oberen Hülsenbereich weist die Hülse einen Zapfen auf, der in eine zentrische Bohrung in der Spindelspitze eingedrückt wird. Dies ist herstellungstechnisch einfacher als eine Ausnehmung mit einem unrunden, z.B. rechteckigen Querschnitt. Wenn man den Zapfen hohl ausführt und zudem noch Lippen im Hohlzapfen gestaltet, kann die Klemmkraft auch im oberen Hülsenbereich erhöht werden. Vorteilhaft wäre, die oberen und unteren Lippen geringfügig nach aussen abzuwinkeln, sodass kleine Herstellungsabweichungen ausgeglichen werden können und bereits bei Stillstehen der Spindel eine Klemmkraft vorhanden ist. Natürlich sollten die Lippen geeignete Abschrägungen haben, die eine leichte Einführung auf die Spindel ermöglichen. Eine horizontale Bohrung, die die aufwärts weisende Bohrung für den Zapfen schneidet, ermöglicht ein automatisches Herausschleudern von darin angesammeltem Flug. Ein wesentlicher Vorteil ist weiterhin, dass die Hülse, samt Schutzring, Hohlzapfen, Verstärkungsrippen und Klemmlippen auf einfache Weise einstückig aus herkömmlichem Kunststoff hergestellt werden kann.This object is solved by the features of the characterizing parts of claims 1 and 12 respectively. The clamping then becomes increasingly stronger when the outer diameter of the sleeve is expanded. Since a sleeve part is pressed against a part of the spindle by the centrifugal force or centripetal force, the coaxial position of the sleeve is retained. The sleeve is preferably clamped on the spindle in its lower and upper end region. In the lower end area of the sleeve, the sleeve lies against a centering edge. The clamping force can be increased by lip formation in the lower sleeve end area. With an interrupted centering edge, there is a self-cleaning effect because fly and loose fibers are automatically thrown away. The presence of a protective ring, which protects the lower sleeve clamping area, especially when dropped, is also inventive. In the upper sleeve area, the sleeve has a pin which is pressed into a central bore in the spindle tip. In terms of manufacturing technology, this is simpler than a recess with a non-circular, for example rectangular, cross section. If you make the pin hollow and also design lips in the hollow pin, the clamping force can also be increased in the upper sleeve area. It would be advantageous to slightly bend the upper and lower lips outwards so that small manufacturing deviations can be compensated for and a clamping force is already present when the spindle is at a standstill. Of course, the lips should have suitable bevels that allow easy insertion on the spindle. A horizontal hole, which cuts the upward hole for the pin, enables the flight of accumulated flight to be automatically ejected. Another major advantage is that the sleeve, including the protective ring, hollow spigot, reinforcing ribs and clamping lips, is simple Way can be made in one piece from conventional plastic.

Die Erfindung wird nunmehr anhand der Zeichnung näher erläutert. Es zeigen:

Fig. 1:
eine Ansicht, teilweise im Schnitt, einer Spindel, wobei eine erfinderische Hülse auf der linken Hälfte der Figur auf der Spindel montiert ist, und
Fig. 2:
eine perspektivische Ansicht eines zur Hülse nach Fig. 1 gehörenden Zapfens.
The invention will now be explained in more detail with reference to the drawing. Show it:
Fig. 1:
a view, partly in section, of a spindle, wherein an inventive sleeve is mounted on the left half of the figure on the spindle, and
Fig. 2:
a perspective view of a peg belonging to the sleeve of FIG. 1.

Eine Spindel 2 hat, wie üblich, einen unteren, leicht konischen Längenabschnitt 3, einen mittleren zylinderischen Längenabschnitt 4 und einen leicht konischen, oberen Längenabschnitt 5. Auch eine Unterwindkrone 8 ist üblich. Darüber hinaus ist ein Zentrierrand, bzw. eine Zentrierkrone 9, oberhalb der Unterwindkrone 8 an der Spindel 2 angeordnet. Der Zentrierrand 9 kann einstückig mit der Spindel verbunden sein und weist vorzugsweise drei über den Umfang gleichmässig verteilte Teilränder 10 auf. Durch die zwischen den Teilrändern 10 befindlichen Einschnitte 11 kann, bei einer leeren und drehenden Spindel Flug usw. herausgeschleudert werden. Zentrisch in der Spitze 15 der Spindel 2 befindet sich eine aufwärtsweisende, vertikale Bohrung 16. Eine horizontale Bohrung 17 erstreckt sich durch die Spindel 2 und schneidet die Bohrung 16. Der Zweck ist das Herausschleudern von in der Bohrung 16 angesammeltem Flug bei einer leeren und drehenden Spindel.A spindle 2 has, as usual, a lower, slightly conical length section 3, a middle cylindrical length section 4 and a slightly conical, upper length section 5. An underwind crown 8 is also common. In addition, a centering edge, or a centering crown 9, is arranged above the underwind crown 8 on the spindle 2. The centering edge 9 can be connected in one piece to the spindle and preferably has three partial edges 10 distributed uniformly over the circumference. Through the incisions 11 located between the partial edges 10, flight etc. can be thrown out when the spindle is empty and rotating. Centrally located in the tip 15 of the spindle 2 is an upward vertical bore 16. A horizontal bore 17 extends through the spindle 2 and intersects the bore 16. The purpose is to eject flight accumulated in the bore 16 with an empty and rotating one Spindle.

Eine einstückige Hülse 21 kontaktiert in der linken Hälfte der Figur 1 die Spindel klemmend an zwei Stellen, oben und unten an der Spindel 2. Ein abwärtsweisender Hohlzapfen 23 der Hülse 21 ist in die Bohrung 16 eingeführt. Der Hohlzapfen 23 hat längliche, unten offene Ausnehmungen 24, wodurch Lippen 25 gebildet werden. Es ist einleuchtend, dass diese Lippen 25 durch die Zentrifugalkraft an den um die Lippen 25 herum angeordneten Spindelteil 15 angedrückt werden und je höher die Zentrifugalkraft, um so fester wird die Klemmung der Hülse 21 auf der Spindel 2, wobei die koaxiale Stellung der Hülse erhalten bleibt. Die Lippen 25 sind leicht, d.h. bis zu einigen Graden, nach aussen abgewinkelt. In der Zeichnung ist dies mit der strichpunktierten Linie 26 angedeutet. Abschrägungen sind angedeutet durch das Bezugszeichen 27. Sie haben den Zweck, den Hohlzapfen 23 leicht in die Bohrung 16 einführen zu können. Damit die wirksame Hublänge der Hülse 21 vergrössert werden kann, befindet sich der Hohlzapfen 23 auf einem Abstand unterhalb des oberen Hülsenendes 30. Zur Erhöhung der Hülsenstabilität sind einige, bspw. 3 Verstärkungsrippen 31 im oberen Hülsenbereich vorgesehen.In the left half of FIG. 1, a one-piece sleeve 21 contacts the spindle in two places, at the top and bottom of the spindle 2. A downward-pointing hollow pin 23 of the sleeve 21 is inserted into the bore 16. The hollow pin 23 has elongated recesses 24 which are open at the bottom, as a result of which lips 25 are formed. It is obvious that these lips 25 are pressed by the centrifugal force on the spindle part 15 arranged around the lips 25 and the higher the centrifugal force, the tighter the clamping of the sleeve 21 on the spindle 2, whereby the coaxial position of the sleeve is maintained remains. The lips 25 are slightly angled outwards, ie up to a few degrees. In the drawing, this is indicated by the dash-dotted line 26. Bevels are indicated by the reference number 27. They have the purpose of being able to easily insert the hollow pin 23 into the bore 16. So that the effective stroke length of the sleeve 21 can be increased, the hollow pin 23 is located at a distance below the upper sleeve end 30. To increase the sleeve stability, some, for example 3, reinforcing ribs 31 are provided in the upper sleeve area.

Im unteren Hülsenendbereich sind ebenfalls Lippen 35 vorgesehen, auf ähnliche, in Fig. 2 gezeigte und beschriebene Art. Auch diese Lippen 35 sind leicht nach aussen abgewinkelt und haben Abschrägungen, genau wie die Abschrägungen 27 des Hohlzapfens 23. Diese Lippen 35 sind umgeben vom Zentrierrand 9 bzw. von den Teilrändern 10. Ein durchgehender Schutzring 39 schützt die Lippen 35 vor Beschädigungen.Lips 35 are also provided in the lower end of the sleeve, in a similar manner, shown and described in FIG. 2. These lips 35 are also slightly angled outwards and have bevels, just like the bevels 27 of the hollow pin 23. These lips 35 are surrounded by the centering edge 9 or from the partial edges 10. A continuous protective ring 39 protects the lips 35 from damage.

Es wird ausdrücklich darauf hingewiesen, dass jedes mögliche Anspruchsgebilde in Erwägung gezogen wurde. So kann bspw. Anspruch 1 mit jedem darauf zurückgezogenen Anspruch allein als auch in beliebiger, sinnvoller Kombination mit anderen darauf rückbezogenen Ansprüchen zusammengelegt werden.It is expressly pointed out that every possible entity has been considered. For example, claim 1 can be merged with each claim withdrawn thereon alone or in any meaningful combination with other claims referring to it.
