Description

Spinnhülse, insbesondere VerbundspinnhülseSpinning tube, in particular composite spinning tube
Beschreibungdescription
Die Erfindung betrifft eine Spinnhülse, insbesondere Ver¬ bundspinnhülse, mit einem Hülsenkörper aus Kunststoff, der zumindest an einem Ende mit einem zumindest zum Teil dem Hülsenkörper axial vorgelagerten Schutzring verbunden ist, dessen Außen- und Innenfläche fluchtend in die Außen- bzw. Innenfläche des Hülsenkörpers übergehen.The invention relates to a spinning sleeve, in particular a composite spinning sleeve, with a sleeve body made of plastic, which is connected at least at one end to a protective ring which is at least partially axially in front of the sleeve body, the outer and inner surfaces of which are flush with the outer and inner surfaces of the sleeve body pass over.
Bei derartigen Spinnhülsen, die insbesondere als Verbund¬ spinnhülsen gleiche Verfahrensstationen aufeinanderfolgend immer wieder durchlaufen, muß mit Beschädigungen insbeson¬ dere am Hülsenfuß gerechnet werden, die aus dem schlagarti- gen Auftreffen der Hülsen in den verschiedenen Halterungen und aus dem Angreifen von Enforraungsschuhen oder derglei¬ chen resultieren. Diese Beschädigungen können in recht kur¬ zer Zeit dazu führen, daß die Hülsen gegen neue ausge¬ tauscht werden müssen, da Beschädigungen gundsätzlich auch Unwuchten darstellen, die bei den immer höher werdenden Drehzahlen der Spinnhülsen zu nicht akzeptablen Störungen führen. Es sind nun bereits aus Blech gestanzte, im Profil U-för- mige Basisringe bekannt, die auf den Fuß des Hülsenkörpes aufgesetzt und dort festgelegt werden. In Anbetracht der Wandstärke des Hülsenkörpers darf die Blechstärke des ver- wendeten Ringes nur relativ gering sein. Die Praxis zeigt, daß ein solcher Ring häufig nicht überall satt auf dem Hül¬ senkörper aufliegt. Insgesamt ergibt sich deshalb, daß auch bei der Verwendung derartiger bekannter Ringe Beschädigun¬ gen auftreten, die die Spinnhülse insgesamt unbrauchbar ma- chen können.With such spinning sleeves, which in particular as composite spinning sleeves pass through the same process stations again and again in succession, damage must be expected, in particular on the sleeve base, which results from the sudden impact of the sleeves in the various holders and from the attack of deformation shoes or the like Chen result. This damage can lead in a very short time to the fact that the sleeves have to be exchanged for new ones, since damage basically also represents imbalances which lead to unacceptable disturbances with the ever increasing speeds of the spinning sleeves. Base rings are now punched out of sheet metal and have a U-shaped profile, which are placed on the base of the sleeve body and fixed there. In view of the wall thickness of the sleeve body, the sheet thickness of the ring used may only be relatively small. Practice shows that such a ring often does not lie snugly on the sleeve body everywhere. Overall, it follows that even when such known rings are used, damage occurs which can render the spinning sleeve unusable overall.
Die Aufgabe der Erfindung besteht nun darin, eine Spinn¬ hülse der eingangs erwähnten Art so auszubilden, daß die dargelegten Nachteile vermieden und insbesondere ihr Fußende zuverlässig gegen bleibende Verformungen geschützt wird.The object of the invention is now to design a spinning sleeve of the type mentioned at the outset in such a way that the disadvantages described are avoided and in particular its foot end is reliably protected against permanent deformations.
Diese Aufgabe wird bei einer Spinnhülse der eingangs er¬ wähnten Art erfindungsgemäß dadurch gelöst, daß der Schutz- ring mit dem Hülsenkörper unlösbar form- oder kraft¬ schlüssig verbunden ist und als massiver, durch Spritzen, Gießen oder spanende Bearbeitung geformter Rotationskörper ausgebildet sowie bei den bei der Verwendung der Spinnhülse vorkommenden Stoß- und Schlagbelastungen nicht plastisch verformbar ist.This object is achieved according to the invention in a spinning tube of the type mentioned at the outset in that the protective ring is non-releasably connected to the tube body in a form-fitting or non-positive manner and is designed as a solid body of revolution formed by injection molding, casting or machining, and in the case of the when using the spinning sleeve occurring shock and impact loads are not plastically deformable.
Eine solche Spinnhülse kann allein an ihrem Fußende oder aber am Fußende und am Kopfende mit je einem Schutzring versehen sein. Das Profil des Schutzringes kann den jeweils zu erwartenden Belastungen optimal angepaßt sein. Beschrän¬ kungen in der Wandstärke, wie sie bei Blechteilen zwangs¬ läufig beachtet werden müssen, fallen hier fort. Die vorge¬ sehene unlösbare form- und kraftschlüssige Verbindung zwi¬ schen dem Schutzring und dem Hülsenkörper gewährleistet die angestrebte Schutzwirkung. Die auftretenden Stoß- und Schlagbelastungen wirken sich entweder wegen der Härte des für den Schutzring verwendeten Materials oder aber wegen der Rückformung des Materials aufgrund der gegebenen Ela¬ stizität nicht bleibend aus. Es kommt also nicht zu pla- stischen Verformungen und damit zur Bildung von Unwuchten mit ihren schädlichen Effekten, insbesondere bei hohen Drehzahlen.Such a spinning sleeve can be provided with a protective ring alone at its foot end or at the foot end and at the head end. The profile of the protective ring can be optimally adapted to the expected loads. Restrictions in the wall thickness, such as must inevitably be observed in sheet metal parts, do not apply here. The provided non-releasable positive and non-positive connection between the protective ring and the sleeve body ensures the desired protective effect. The shock and impact loads that occur do not have a permanent effect either because of the hardness of the material used for the protective ring or because of the reshaping of the material due to the given elasticity. So there is no static deformations and thus the formation of unbalances with their harmful effects, especially at high speeds.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß sich der Schutzring bei freiem Fall der bespulten Spinnhülse auf eine Stahlunterlage aus mindestens einem Me¬ ter Höhe nicht plastisch verformt. Auch wenn eine solche Spinnhülse im bespulten Zustand verkantet auf ihre Unter- läge trifft, kommt es nicht zu bleibenden Verformungen.The spinning sleeve according to the invention can also be designed such that the protective ring does not plastically deform from a height of at least one meter when the spooled spool is free-falling on a steel base. Even if such a spinning tube hits its base when it is spooled, there are no permanent deformations.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß der Schutzring aus Keramik, Kunststoff oder Me¬ tall gebildet ist. Diese Materialien können so ausgewählt werden, daß sie die aufkommenden Stoß- und Schlagbelastun¬ gen aushalten, dabei aber keinerlei Verformungen erfahren.The spinning sleeve according to the invention can also be designed such that the protective ring is formed from ceramic, plastic or metal. These materials can be selected in such a way that they can withstand the occurring shock and impact loads, but do not experience any deformations in the process.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß der Schutzring aus Gummi oder einem gummiartigen Material gebildet ist. Bei der Verwendung dieses Materials ist bei den auftretenden Belastungen mit Verformungen zu rechnen, die aber elastisch sind, sich also in die Aus¬ gangsform zurückbilden. Auch auf diese Weise werden pla¬ stische Verformungen ausgeschlossen, die zu Unwuchten füh- ren würden. Die Verwendung von Gummi oder einem gummiarti¬ gen Material führt darüber hinaus zu Vorteilen bei der Lärmentwicklung in Spinnsälen, in denen in schneller Auf¬ einanderfolge die Spinnhülsen immer wieder in die jeweils nächste Halterung eingesetzt werden.The spinning sleeve according to the invention can also be designed so that the protective ring is made of rubber or a rubber-like material. When using this material, deformations are to be expected in the case of the loads which occur, but which are elastic, that is to say they regress into the original form. In this way too, plastic deformations which would lead to imbalance are excluded. The use of rubber or a rubber-like material also leads to advantages in the development of noise in spinning halls, in which the spinning sleeves are repeatedly inserted into the next holder in rapid succession.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß der Schutzring auf seiner dem Hülsenkörper zuge¬ wandten Seite mindestens eine in den Hülsenkörper eingebet¬ tete, von dem Kunststoff des Hülsenkörpers ausgefüllte Hin- terschneidung hat. Auf diese Weise kann eine zuverlässige formschlüssige Verbindung zwischen Schutzring und Hülsen¬ körper erreicht werden.The spinning sleeve according to the invention can also be designed such that the protective ring on its side facing the sleeve body has at least one undercut embedded in the sleeve body and filled by the plastic of the sleeve body. In this way, a reliable positive connection between the protective ring and the sleeve body can be achieved.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß der Schutzring einen in die Wand des Hülsenkör¬ pers eingebetteten Bund aufweist, der mit mindestens einer Hinterschneidung versehen ist.The spinning sleeve according to the invention can also be designed in this way be that the protective ring has a collar embedded in the wall of the sleeve body, which is provided with at least one undercut.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß der Bund axial verläuft und mit radialen Öffnun¬ gen versehen ist. Dabei wirken die Öffnungen wie Hinter- schneidungen und gewährleisten folglich eine sichere Fest¬ legung des Schutzrings am Hülsenkörper.The spinning sleeve according to the invention can also be designed so that the collar extends axially and is provided with radial openings. The openings act like undercuts and consequently ensure that the protective ring is securely attached to the sleeve body.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß der Bund mit mindestens einer Ringschulter verse¬ hen ist. Auch auf diese Weise kann eine zuverlässige Veran¬ kerung des Schutzringes am Hülsenkörper sichergestellt werden.The spinning sleeve according to the invention can also be designed such that the collar is provided with at least one ring shoulder. Reliable anchoring of the protective ring on the sleeve body can also be ensured in this way.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß die Innenfläche des Bundes mit der Innenfläche des Hülsenkörpers fluchtet.The spinning sleeve according to the invention can also be designed such that the inner surface of the collar is flush with the inner surface of the sleeve body.
Die erfindungsgemäße Spinnhülse kann ferner so ausgebildet sein, daß der Bund radial innen wie radial außen von dem Kunststoff des Hülsenkörpers umschlossen ist.The spinning sleeve according to the invention can also be designed such that the collar is enclosed radially on the inside and radially outside by the plastic of the sleeve body.
Schließlich kann die erfindungsgemäße Spinnhülse so ausge¬ bildet sein, daß sie an Ihren beiden Enden je einen Schutz¬ ring aufweist und daß beide Schutzringe aus gleichem oder unterschiedlichem Material bestehen. Die für die Schutz¬ ringe an den beiden Enden der Spinnhülse verwendeten Mate- rialien können den jeweiligen Beanspruchungen des be¬ troffenen Hülsenteils entsprechend gewählt werden, um in ausreichender Weise Verformungen auszuschließen und die Lärmbelastung zu reduzieren.Finally, the spinning sleeve according to the invention can be designed such that it has a protective ring at each of its two ends and that both protective rings are made of the same or different material. The materials used for the protective rings at the two ends of the spinning sleeve can be selected in accordance with the respective stresses of the sleeve part concerned in order to exclude deformations sufficiently and to reduce the noise pollution.
Im folgenden Teil der Beschreibung wird eine Ausführungs¬ form der erfindungsgemäßen Spinnhülse anhand von Zeichnun¬ gen beschrieben. Es zeigt:In the following part of the description, an embodiment of the spinning sleeve according to the invention is described on the basis of drawings. It shows:

Fig. 1 zeigt eine Spinnhülse mit einem Hülsenkörper 1 aus thermoplastischem Kunststoff zum Aufwickeln, Transportieren und Lagern von Fäden und Garnen. Diese Spinnhülse ist ins¬ besondere als Verbundspinnhülse geeignet. Sie verjüngt sich von einem Hülsenfuß 2 zu einem Hülsenkopf 3.Fig. 1 shows a spinning tube with a tube body 1 made of thermoplastic material for winding, transporting and storing threads and yarns. This spinning sleeve is particularly suitable as a composite spinning sleeve. It tapers from a sleeve base 2 to a sleeve head 3.
Am Hülsenkopf 3 der Spinnhülse ist mit dem Hülsenkörper 1 ein Schutzring 4 fest verbunden, der anhand der Figuren 2 und 3 im einzelnen beschrieben wird.A protective ring 4, which is described in detail with reference to FIGS. 2 and 3, is firmly connected to the sleeve body 1 on the sleeve head 3 of the spinning sleeve.
Der Schutzring 4 ist ein massives, formstabiles Drehteil, das durch spanende Bearbeitung aus Stahl hergestellt ist. Es hat einen Schutzabschnitt 5, der bei Verbindung mit dem Hülsenkörper 1 den unteren Rand der Spinnhülse bildet. Bei der dargestellten Ausführungsform geht von dem radial innen liegenden Bereich des Schutzabschnitts 5 ein Verbin¬ dungsabschnitt 6 aus, dessen Innenfläche 7 mit der sich daran anschließenden Innenfläche 8 der Spinnhülse aus- gerichtet ist. Von dem freien Ende des Verbindungsab¬ schnitts 6 geht eine radial nach außen vorspringende Ring¬ schulter 9 aus, die eine Hinterschneidung 10 bildet.The protective ring 4 is a solid, dimensionally stable turned part, which is made of steel by machining. It has a protective section 5 which, when connected to the sleeve body 1, forms the lower edge of the spinning sleeve. In the embodiment shown, a connection section 6 starts from the radially inner region of the protective section 5, the inner surface 7 of which is aligned with the adjoining inner surface 8 of the spinning sleeve. A radially outwardly projecting annular shoulder 9, which forms an undercut 10, extends from the free end of the connecting section 6.
Die Wandstärke des Schutzabschnitts 5, der Stoß- und Schlagbelastungen ausgesetzt ist, ist deutlich größer als die des Verbindungsabschnitts 7.The wall thickness of the protective section 5, which is exposed to shock and impact loads, is significantly larger than that of the connecting section 7.
Der Schutzabschnitt 5 hat eine Außenfläche 11, die mit ei¬ ner Außenfläche 12 des Hülsenkörpers 1 der Spinnhülse fluchtet.The protective section 5 has an outer surface 11 which is aligned with an outer surface 12 of the sleeve body 1 of the spinning sleeve.
Die Innenfläche des Schutzabschnitts 5 weist eine Eindel- lung 13 auf, die lediglich herstellungstechnische Funktion hat.The inner surface of the protective section 5 has an indentation 13 which only has a manufacturing function.
Wie Fig. 1 zeigt, ist der Schutzring 4 in den unteren Be¬ reich des Hülsenkörpers 1 eingebettet, so daß der Kunst¬ stoff des Hülsenkörpers 1 sich unmittelbar an das Profil des Basisrings 4 anlegt und lediglich die Innenfläche 7, die Außenfläche 11 und die Stirnfläche 14 des Schutzab¬ schnitts 5 freiläßt. Eine solche innige Verbindung zwischen Hülsenkörper 1 und Besisring 4 kann durch Umspritzen er¬ zielt werden.1 shows, the protective ring 4 is embedded in the lower region of the sleeve body 1, so that the plastic of the sleeve body 1 lies directly against the profile of the base ring 4 and only the inner surface 7, the outer surface 11 and the Leaves end face 14 of the protective section 5. Such an intimate connection between sleeve body 1 and besis ring 4 can be achieved by extrusion coating.
Entsprechend dem Schutzring 4 kann auch am Hülsenkopf 3 ein nicht dargestellter Schutzring vorgesehen sein.According to the protective ring 4, a protective ring (not shown) can also be provided on the sleeve head 3.
Anhand der Fig. 4 und 5 soll nun eine weitere Ausführungs¬ form eines erfindungsgemäßen Schutzrings 20 beschrieben werden, der wie der zuvor beschriebene Schutzring, einen Schutzabschnitt 21 mit einer Außenfläche 22 und einer In¬ nenfläche 23 hat. Die Außenfläche 22 und die Innenfläche 23 des Schutzabschnitts 21 fluchten mit der Außenfläche 12 bzw. der Innenfläche 8 eines Hülsenkörpers 1, wie er in Fig. 1 dargestellt ist.4 and 5, a further embodiment of a protective ring 20 according to the invention will now be described which, like the protective ring described above, has a protective section 21 with an outer surface 22 and an inner surface 23. The outer surface 22 and the inner surface 23 of the protective section 21 are aligned with the outer surface 12 and the inner surface 8 of a sleeve body 1, as shown in FIG Fig. 1 is shown.
Von dem Schutzabschnitt 21 geht in axialer Richtung ein Bund 24 aus, dessen am weitesten axial vorstehendes Ende mit einer äußeren Ringschulter 25 und einer inneren Ring¬ schulter 26 versehen ist. Die beiden Ringschultern 25,26 bilden Hinterschneidungen 27,28, die im Verbund des Schutz¬ ringes mit der Spinnhülse von dem Kunststoff des Hülsenkör¬ pers 1 ausgefüllt sind, so daß eine formschlüssige Verbin- düng zwischen dem Hülsenkörper 1 und dem Schutzring 20 vor¬ liegt. Der Bund 24 und die Ringschultern 25,26 liegen dabei innerhalb der Wandung des Hülsenkörpers 1.A collar 24 extends from the protective section 21 in the axial direction, the most axially projecting end of which is provided with an outer ring shoulder 25 and an inner ring shoulder 26. The two ring shoulders 25, 26 form undercuts 27, 28, which in the connection of the protective ring with the spinning sleeve are filled with the plastic of the sleeve body 1, so that a positive connection between the sleeve body 1 and the protective ring 20 is provided lies. The collar 24 and the annular shoulders 25, 26 lie within the wall of the sleeve body 1.
Nach einer weiteren Ausführungsform der erfindungsgemäßen Spinnhülse ist es möglich, einen Schutzring 20 zu verwen¬ den, der keinerlei Hinterschneidungen aufweist, sondern mit dem Hülsenkörper 1 verklebt oder verschweißt ist.According to a further embodiment of the spinning sleeve according to the invention, it is possible to use a protective ring 20 which has no undercuts, but is glued or welded to the sleeve body 1.
In den Fig. 6 und 7 ist eine weitere Ausführungsform eines Schutzrings 29 der erfindungsgemäßen Spinnhülse darge¬ stellt. Dieser Schutzring hat einen Schutzabschnitt 30, dessen Ausbildung derjenigen nach den zuvor beschriebenen Ausführungsformen im wesentlichen entspricht. Von dem Schutzabschnitt 30 geht ein axial verlaufender Bund 31 aus, der über seinen Umfang verteilt radial verlaufende Öffnun¬ gen 32 hat. Im Verbund mit einem Hülsenkörper 1 gemäß Fig. 1 kommt der Bund 31 in der Wandung dieses Hülsenkörpers 1 zu liegen. Beim Spritzen des Hülsenkörpers 1 tritt der Kunststoff durch die Öffnungen 32 hindurch, umschließt den Bund 31 und legt sich an die zugewandte Seite des Schutzab¬ schnitts 30 eng an. Auch auf diese Weise kommt es zu einr formschlüssigen Verbindung zwischen dem Schutzring 29 und einem Hülsenkörper 1.6 and 7 show a further embodiment of a protective ring 29 of the spinning sleeve according to the invention. This protective ring has a protective section 30, the design of which essentially corresponds to that according to the previously described embodiments. An axially extending collar 31 extends from the protective section 30 and has openings 32 which extend radially over its circumference. In conjunction with a sleeve body 1 according to FIG. 1, the collar 31 comes to rest in the wall of this sleeve body 1. When the sleeve body 1 is injected, the plastic passes through the openings 32, surrounds the collar 31 and lies closely against the side of the protective section 30 facing it. In this way, too, there is a positive connection between the protective ring 29 and a sleeve body 1.
Für die Herstellung der Schutzringe kommt in allen ihren Ausführungsformen Keramik, Kunststoff, Metall, Gummi oder gummiartiges Material in Betracht. Alle Ausführungsformen des Schutzrings können sowohl am Fußende wie auch am Kopfende eines Hülsenkörpers 1 angebracht werden. Dabei können Schutzringe abweichender Formgebung und/oder abwei¬ chenden Materials an den beiden Enden eines Hülsenkörpers 1 zum Einsatz kommen. Ceramic, plastic, metal, rubber or rubber-like material come into consideration in all of their embodiments for the production of the protective rings. All embodiments of the protective ring can be attached to both the foot end and the head end of a sleeve body 1. there protective rings of different shapes and / or different materials can be used at the two ends of a sleeve body 1.
