Definitions
- weft spools the spool material arranged on bobbins, e.g. Plastic ribbon tapes, carry, clamped by means of spring force between two receiving devices in the shuttle.
- side windows are attached to the weft coil bodies before they are clamped in the shuttle.
- the side windows serve to catch winding loops falling down from the coil winding. These loose loops can occur due to imperfection of the coil winding or uneven tensile stresses on the Spulgut.
- the coils are rotated, resulting in a relative movement between the bobbin tubes and the side windows. As a result, rub the ends of the bobbin tubes on the side windows.
- aluminum shot sleeve sleeves the abrasion through the side windows, which are usually reinforced with steel rings, is very high, as a result of which the bobbin sleeves become shorter and shorter.
- Another problem is the dust that results when abrading bobbin tubes (especially aluminum). On the one hand, it damages the bearings of the receptacles, and on the other hand, the fabric is polluted by the dust.
- a relative movement of the side windows with respect to the phenolic resin layer and the flanged ends of the bobbin tube is made difficult, but not impossible, by the frictional forces exerted on the side plates by the phenolic resin layer and the ends of the bobbin tube.

- the plugs are thus rotated against the bobbin tube.
- the plugs serve as supports for receiving devices. The preparation of these coils is complicated and expensive, because it requires many operations.
- the present invention solves this problem by providing a bobbin with a cylindrical bobbin tube and arranged at the ends of the bobbin tube protection rings, wherein the bobbin tube on its inner surface at least one inwardly directed, at least partially axially extending web and the protective rings with the at least one web form fit secured against rotation, for example by pressing.
- the at least one web is directed radially inwardly in one embodiment of the invention.
- the positive connection has the function of a Mutual toothing of the bobbin tube and protective rings, which reliably prevents a rotation of the guard rings with respect to the bobbin tube.
- the bobbin tube is protected from wear by abrasion at its ends, whereby its length remains constant, which gives the bobbin an extremely long life. Only the protective rings are replaced if necessary.
- a bobbin having a high rigidity is obtained when the bobbin tube has a plurality of webs which are arranged uniformly or non-uniformly spaced around the circumference of the inner surface of the bobbin tube. Maximum rigidity is achieved if the at least one web extends axially over the entire length of the bobbin tube.

Description
Auf dem Gebiet der Rundwebtechnik werden Schussspulen, die auf Spulenkörpern angeordnetes Spulgut, z.B. Schussbändchenwickel aus Kunststoff, tragen, mittels Federkraft zwischen zwei Aufnahmeeinrichtungen in Webschützen eingeklemmt. Üblicherweise werden sogenannte Seitenscheiben an den Schussspulenkörpern angebracht, bevor diese im Webschütz eingespannt werden. Die Seitenscheiben dienen dazu, vom Spulenwickel herunterfallende Spulgutschlaufen aufzufangen. Diese losen Schlaufen können durch Unvollkommenheit der Spulenwickel oder ungleichmäßige Zugspannungen auf das Spulgut auftreten. Beim Abwickeln des Spulgutes während des Webvorgangs werden die Spulen in Rotation versetzt, wobei es zu einer Relativbewegung zwischen den Spulenhülsen und den Seitenscheiben kommt. Dadurch reiben die Enden der Spulenhülsen an den Seitenscheiben. Insbesondere bei Schussspulenhülsen aus Aluminium ist der Abrieb durch die Seitenscheiben, die üblicherweise mit Stahlringen verstärkt sind, sehr hoch, wodurch die Spulenhülsen immer kürzer werden.In the field of round weaving technology, weft spools, the spool material arranged on bobbins, e.g. Plastic ribbon tapes, carry, clamped by means of spring force between two receiving devices in the shuttle. Usually so-called side windows are attached to the weft coil bodies before they are clamped in the shuttle. The side windows serve to catch winding loops falling down from the coil winding. These loose loops can occur due to imperfection of the coil winding or uneven tensile stresses on the Spulgut. When unwinding the Spulgutes during the weaving process, the coils are rotated, resulting in a relative movement between the bobbin tubes and the side windows. As a result, rub the ends of the bobbin tubes on the side windows. Especially with aluminum shot sleeve sleeves the abrasion through the side windows, which are usually reinforced with steel rings, is very high, as a result of which the bobbin sleeves become shorter and shorter.
Durch die Verkürzung der Spulenhülsen wird die von den Aufnahmeeinrichtungen am Webschütz auf die Spulenhülsen ausgeübte Federkraft verringert. Dadurch wird ein Trudeln der Spule beim Abwickeln des Spulgutes begünstigt, und die Gefahr, dass die Spule bei laufendem Webschütz aus dieser Aufnahmeeinrichtung fällt, steigt mit zunehmendem Verschleiß der Spulenhülse. Bereits ab einer Abnützung von ca. 2 % der Gesamtlänge der Spulenhülsen ist ein sicherer Halt im Webschütz während des Webens nicht mehr gewährleistet und die Hülsen müssen entsorgt werden.By shortening the bobbin tubes, the spring force exerted by the receiving devices on the shuttle on the bobbins is reduced. As a result, spinning of the bobbin during unwinding of the package material is favored, and the risk that the bobbin falls from the receiving device when the weft is running increases with increasing wear on the bobbin tube. Already from a wear of about 2% of the total length of the bobbin tubes a secure hold in the wiper during weaving is no longer guaranteed and the sleeves must be disposed of.
Durch die stetig steigende Leistung von Rundwebmaschinen steigt die Drehzahl der Spulen beim Weben und damit der Verschleiß ihrer Spulenhülsen an und stellt ein immer größer werdendes Problem dar, da die Spulen nur mehr eine sehr geringe Lebensdauer haben.Due to the steadily increasing performance of looms, the speed of the coils during weaving and thus the wear of their bobbin tubes increases and represents an ever-increasing problem, since the coils have only a very short life.
Ein weiteres Problem bildet der Staub, der beim Abreiben von Spulenhülsen (insbesondere aus Aluminium) entsteht. Er beschädigt einerseits die Lager der Aufnahmeeinrichtungen, und andererseits wird das Gewebe durch den Staub verschmutzt.Another problem is the dust that results when abrading bobbin tubes (especially aluminum). On the one hand, it damages the bearings of the receptacles, and on the other hand, the fabric is polluted by the dust.
Eine Alternative zu Spulenhülsen aus Aluminium stellen Hülsen aus mit Phenolharz getränktem Papier dar, da diese geringeren Verschleiß an den Seitenscheiben aufweisen. Die Fertigung dieser Hülsen ist jedoch sehr aufwändig und teuer.An alternative to spool sleeves made of aluminum are sleeves made of phenol resin impregnated paper, since they have less wear on the side windows. However, the production of these sleeves is very complicated and expensive.
Aus dem Dokument
Es besteht somit nach wie vor ein Bedürfnis nach Spulenkörpern, die weitgehend verschleißfreie Spulenhülsen umfassen, deren Dimensionen, insbesondere deren Länge, im Betrieb auch bei hoher Beanspruchung konstant bleibt, die hohe Steifigkeit aufweisen und die außerdem billig und einfach herstellbar sind.There is therefore still a need for bobbins that include largely wear-free bobbin tubes whose dimensions, in particular their length remains constant during operation even at high stress, which have high rigidity and are also cheap and easy to produce.
Die vorliegende Erfindung löst die gestellte Aufgabe durch Bereitstellen eines Spulenkörpers mit einer zylindrischen Spulenhülse und an den Enden der Spulenhülse angeordneten Schutzringen, wobei die Spulenhülse an ihrer Innenfläche zumindest einen einwärts gerichteten, zumindest abschnittsweise axial verlaufenden Steg aufweist und die Schutzringe mit dem zumindest einen Steg formschlüssig gegen Verdrehen gesichert sind, beispielsweise durch Einpressen. Der zumindest eine Steg ist in einer Ausführungsform der Erfindung radial einwärts gerichtet. Die formschlüssige Verbindung hat die Funktion einer gegenseitigen Verzahnung von Spulenhülse und Schutzringen, die eine Verdrehung der Schutzringe in Bezug auf die Spulenhülse verlässlich verhindert. Dadurch ist die Spulenhülse vor Verschleiß durch Abreiben an ihren Enden geschützt, wodurch ihre Länge konstant bleibt, was dem Spulenkörper eine extrem lange Lebensdauer verleiht. Es werden lediglich die Schutzringe bei Bedarf getauscht.The present invention solves this problem by providing a bobbin with a cylindrical bobbin tube and arranged at the ends of the bobbin tube protection rings, wherein the bobbin tube on its inner surface at least one inwardly directed, at least partially axially extending web and the protective rings with the at least one web form fit secured against rotation, for example by pressing. The at least one web is directed radially inwardly in one embodiment of the invention. The positive connection has the function of a Mutual toothing of the bobbin tube and protective rings, which reliably prevents a rotation of the guard rings with respect to the bobbin tube. As a result, the bobbin tube is protected from wear by abrasion at its ends, whereby its length remains constant, which gives the bobbin an extremely long life. Only the protective rings are replaced if necessary.
Man erhält einen Spulenkörper mit hoher Steifigkeit, wenn die Spulenhülse eine Mehrzahl von Stegen aufweist, die um den Umfang der Innenfläche der Spulenhülse gleichmäßig oder ungleichmäßig voneinander beabstandet angeordnet sind. Höchste Steifigkeit wird erzielt, wenn der zumindest eine Steg axial über die gesamte Länge der Spulenhülse verläuft. Diese Ausführungsform der Spulenhülse eignet sich auch hervorragend für die Herstellung mittels Strangpressverfahren. In einer alternativen Ausführungsform umfasst der zumindest eine Steg voneinander getrennte Abschnitte, die jeweils von einem der Enden der Spulenhülse axial zur Spulenkörpermitte hin verlaufen. Auch diese Ausführungsform bietet hohe Steifigkeit, insbesondere an den Endbereichen der Spulenhülse, die durch die Federkraftbeaufschlagung von Aufnahmeeinrichtungen der Webschützen besonders hoch belastet sind. Durch die hohe Steifigkeit des erfindungsgemäßen Spulenkörpers ist es möglich, gegenüber herkömmlichen Spulenkörpern den Außendurchmesser der Spulenhülse im Vergleich zum Innendurchmesser, der von der Spulenaufnahmeeinrichtung abhängig ist, zu vergrößern, ohne dabei den Materialaufwand enorm zu erhöhen. Durch den größeren Außendurchmesser wiederum wird die Drehgeschwindigkeit beim Abwickeln leer werdender Spulen geringer gehalten, was zu einer geringeren Lagerreibung und geringeren Fadenspannung führt.A bobbin having a high rigidity is obtained when the bobbin tube has a plurality of webs which are arranged uniformly or non-uniformly spaced around the circumference of the inner surface of the bobbin tube. Maximum rigidity is achieved if the at least one web extends axially over the entire length of the bobbin tube. This embodiment of the bobbin tube is also ideal for production by means of extrusion molding. In an alternative embodiment, the at least one web comprises mutually separate sections, each extending axially from one of the ends of the bobbin tube towards the bobbin center. This embodiment also offers high rigidity, in particular at the end regions of the bobbin tube, which are subjected to particularly high loads by the spring force loading of receiving devices of the shuttle. Due to the high rigidity of the bobbin according to the invention, it is possible over conventional bobbins to increase the outer diameter of the bobbin tube compared to the inner diameter, which is dependent on the coil receiving device, without increasing the cost of materials enormously. Due to the larger outer diameter, in turn, the rotational speed when unwinding empty coils is kept lower, resulting in a lower bearing friction and lower thread tension.
Axialbewegungen der Schutzringe in Bezug auf die Spulenhülse werden beträchtlich erschwert, wenn der zumindest eine Steg zumindest einen sich in Umfangsrichtung der Spulenhülse erstreckenden Abschnitt aufweist. Der Steg kann im Querschnitt gesehen beispielsweise T-Form, Y-Form oder L-Form aufweisen. Diese Ausführungsform der Spulenhülse führt zu einer Vergrößerung der Grenzfläche der formschlüssigen Verbindung zwischen Spulenhülse und Schutzringen, die die gegenseitige Reibung erhöht und somit ein Herausbewegen der Schutzringe von der Spulenhülse verhindert.Axial movements of the guard rings with respect to the bobbin tube are considerably more difficult if the at least one web has at least one section extending in the circumferential direction of the bobbin tube. The web can be seen in cross-section, for example, T-shape, Y-shape or L-shape. This embodiment of the bobbin tube leads to an enlargement of the interface of the positive connection between the bobbin tube and protective rings, which increases the mutual friction and thus prevents the protective rings from moving out of the bobbin tube.
In einer Ausführungsform der Erfindung ist der Außendurchmesser der Schutzringe kleiner oder gleich dem Außendurchmesser der Spulenhülse ist. Man kann jedoch den Schutzringen zusätzlich die Funktion von Seitenscheiben verleihen, die ein Herunterfallen von Spulgutschlaufen verhindern, indem man den Außenumfang der Schutzringe größer dimensioniert als den Außenumfang der Spulenhülse. Vorzugsweise ist in diesem Fall der Außendurchmesser so groß wie der maximale Durchmesser eines auf die Spulenhülse aufgewickelten Spulgutwickels. In einer alternativen Ausgestaltung, die ebenfalls das Herunterfallen von Spulgutschlaufen verlässlich verhindert, sind an den Enden des Spulenkörpers Seitenscheiben angeordnet, die mit dem zumindest einen Steg der Spulenhülse formschlüssig gegen Verdrehen gesichert verbunden sind. Als vorteilhaft in Bezug auf Verschleiß und Steifigkeit hat sich erwiesen, wenn die Seitenscheiben aus einem Kunststoff, vorzugsweise Polyamid, gefertigt sind, wobei der Kunststoff optional faserverstärkt ist. Aus denselben Gründen erweist es sich als günstig, wenn die Schutzringe aus einem Kunststoff, vorzugsweise Polyamid, gefertigt sind, wobei der Kunststoff optional faserverstärkt ist.In one embodiment of the invention, the outer diameter of the guard rings is less than or equal to the outer diameter of the bobbin tube. However, one can also give the protection rings the function of side windows, which prevent falling of Spulgutschlaufen by the outer circumference of the protective rings larger dimensions than the outer circumference of the bobbin tube. Preferably, in this case the Outer diameter as large as the maximum diameter of a wound on the bobbin Spulgutwickels. In an alternative embodiment, which also reliably prevents the falling of Spulgutschlaufen, side windows are arranged at the ends of the bobbin, which are positively connected to the at least one web of the bobbin sleeve secured against rotation. It has proven to be advantageous in terms of wear and stiffness if the side windows are made of a plastic, preferably polyamide, wherein the plastic is optionally fiber-reinforced. For the same reasons, it proves to be advantageous if the protective rings are made of a plastic, preferably polyamide, wherein the plastic is optionally fiber-reinforced.
In einer bevorzugten Ausführungsform der Erfindung ist die Spulenhülse aus Metall, insbesondere Aluminium oder einer Aluminiumlegierung gefertigt, wobei die Spulenhülse vorzugsweise im Strangpressverfahren hergestellt ist. Diese Spulenhülse zeigt hohe Steifigkeit, geringes Gewicht und geringen Verschleiß.In a preferred embodiment of the invention, the bobbin tube is made of metal, in particular aluminum or an aluminum alloy, wherein the bobbin tube is preferably produced by the extrusion process. This bobbin tube shows high rigidity, low weight and low wear.

Durch die nachfolgend beschriebenen Maßnahmen gelingt es, Abrieb an der Spulenhülse 2 zu vermeiden und somit ihre Länge über die gesamte Lebensdauer des Spulenkörpers 1 konstant zu halten. Durch die konstant bleibende Länge der Spulenhülse 2 ist auch eine gleichbleibende Federkraft beim Einklemmen des Spulenkörpers 1 zwischen die Aufnahmeeinrichtungen 5 im Webschütz 7 gewährleistet. Die Aufnahmeeinrichtungen 5 können sowohl zylindrisch als auch konisch ausgeführt sein.By the measures described below, it is possible to avoid abrasion on the
In der einfachsten Ausführungsform sind die Stege 2c nur radial einwärts gerichtet.
Durch die Stege 2c, 2d erhält die Spulenhülse 2, 2', 2" eine hervorragende Steifigkeit, so dass im Vergleich zu herkömmlichen Spulenkörpern der Außendurchmesser a vergrößert werden kann, was zu verringerten Drehzahlen beim Abziehen des Spulguts führt. Der an den Stegen 2c, 2d gemessene Innendurchmesser b hängt von der Spulenaufnahmeeinrichtung 5 ab. Weiters kann das Gewicht der Spulenhülse 2, 2', 2" durch die Stege 2c, 2d trotz großem Außendurchmesser a gering gehalten werden. Besonders in der Rundweberei ist es wichtig das Gewicht der einzelnen Komponenten, wie Webschütz 7 bzw. Spulenkörper 1, gering zu halten, um den Verschleiß der Bauteile, die durch die Fliehkraft der Webschützen 7 belastet werden, zu minimieren.By means of the
Die Stege 2c, 2d der beschriebenen Ausführungsformen der Spulenhülse 2, 2', 2" sind alle nach innen offen und können einfach mittels Strangpressen hergestellt werden. In die offenen Enden der Spulenhülse 2, 2', 2" sind axial Schutzringe 3 einführbar, so dass sie mit den Stegen 2c, 2d formschlüssig gegen Verdrehen gesichert verbunden sind. In
Wenn der Außendurchmesser d der Schutzringe 3 gleich groß ist wie der Außendurchmesser a der Spulenhülse 2, 2', 2", so ist die Außenfläche 2a der Spulenhülse 2, 2', 2" bündig mit der Außenumfangsfläche 3d des Schutzrings. Eine solche Ausführungsform ist dann zweckmäßig, wenn das Spulgut mit hoher Qualität auf den Spulenkörper gewickelt ist, so dass nicht befürchtet werden muss, dass Spulgutschlaufen vom Spulenwickel fallen. In diesem Fall werden die Schutzringe 3 als Gegenstücke zu den Spulenaufnahmeeinrichtungen 5 ausgebildet. Ist eine solche hohe Qualität des Spulgutwickels nicht garantiert, so ist eine Ausführungsform des Spulenkörpers zweckmäßig, bei der der Außendurchmesser d des ringförmigen Körpers 3c' der Schutzringe 3' größer ist als der Außendurchmesser a der Spulenhülse 2, 2', 2". Dadurch ragt der Schutzring 3 radial nach außen über die Spulenhülse 2, 2', 2" hinaus und erfüllt so die Funktion einer in
