Abstract

In a package carrier for receiving yarns, with a rotationally symmetrical one-piece or multi-piece body forming a supporting surface (2) carrying the yarn, the body (1) is equipped at each of its two ends with an annularly extending toothing (3, 4; 13, 14). The teeth (5, 6; 15) of this toothing (3, 4; 13, 14) project in the axial direction, and their radially outer faces adjoin the supporting surface (2) continuously. Their outside diameters are identical to one another. The teeth (5, 6; 15) of one toothing (3, 4; 13, 14) are matched respectively to the tooth interspaces of the other toothing (3, 4; 13, 14). The package carrier is wound with yarn from the region of one toothing (3, 4; 13, 14) into the region of the other toothing (3, 4; 13, 14). The sum of the axial lengths of the wound regions of the two toothings (3, 4; 13, 14) corresponds essentially to the amount by which the toothings of axially adjacent package carriers can be introduced into one another. <IMAGE>

Description

Die Erfindung betrifft einen Wickelträger zur Aufnahme von Garnen, mit einem rotationssymmetrischen Körper, der eine das Garn tragende Tragfläche bildet, wobei der Körper an seinen beiden Enden jeweils mit einer ringförmig verlaufen­den Verzahnung versehen ist, deren Zähne in axialer Rich­tung vorstehen und deren radial außen liegende Flächen sich stufenlos an die Tragfläche anschließen sowie untereinander gleiche Durchmesser haben, und wobei die Zähne der einen Verzahnung jeweils den Zahnzwischenräumen der anderen Ver­zahnung angepaßt sind.The invention relates to a winding support for receiving yarns, with a rotationally symmetrical body that forms a wing supporting the yarn, the body being provided at both ends with an annular toothing, the teeth of which protrude in the axial direction and the radially outer ones Surfaces connect continuously to the wing and have the same diameter among each other, and the teeth of one toothing are each adapted to the interdental spaces of the other toothing.

Es ist bekannt, derartige Wickelträger, nachdem sie mit ei­nem Garnwickel versehen worden sind, axial übereinander an­zuordnen. Auf diese Weise wird der für die bespulten Wickelträger erforderliche Lager- und/oder Transportraum reduziert. Weiter ist es bekannt, derartige Wickelträger geführt von einem Färbespeer oder einer Färbespindel zum Zwecke der Behandlung des Garnwickels mit einem Behand­lungsmedium, insbesondere zum Färben, axial übereinander anzuordnen. Dabei werden die von den einzelnen Wickelträ­gern getragenen Wickel zu einer möglichst homogenen Garn­säule zusammengepreßt mit dem Ziel, über die gesamte Höhe dieser Säule für das Behandlungsmedium gleiche Durchströ­mungsverhältnisse zu erhalten.It is known to arrange such winding carriers axially one above the other after they have been provided with a yarn package. In this way, the storage and / or transport space required for the wound winding carrier is reduced. Furthermore, it is known to arrange such winding carriers guided axially one above the other by a dye spear or a dyeing spindle for the purpose of treating the yarn winding with a treatment medium, in particular for dyeing. The coils carried by the individual winding carriers are pressed together to form a yarn column that is as homogeneous as possible with the aim of maintaining the same flow conditions for the treatment medium over the entire height of this column.

Es sind Wickelträger bekannt, bei denen die für die Auf­nahme des Garns vorgesehene Tragfläche zumindest an einem Ende des Wickelträgers durch einen geschlossenen Endring begrenzt ist, der gegenüber der Tragfläche radial nach außen vorspringt.Winding supports are known in which the supporting surface provided for receiving the yarn is delimited at least at one end of the winding support by a closed end ring which extends radially relative to the supporting surface protrudes outside.

Beim Bespulen dieser bekannten Wickelträger müssen die bei­den Stirnflächen der erzeugten Wickel stets einen Abstand von dem benachbarten Ende des Wickelträgers frei lassen, so daß bei dem bespulten Wickelträger immer beide Enden des Wickelträgers ein Stück aus dem Wickel herausstehen. In ei­nem solchen vorstehenden Stück des Wickelträgers kann sich z.B. ein radial vorstehender Endring befinden.When this known winding carrier is wound, the two end faces of the winding produced must always leave a distance from the adjacent end of the winding carrier, so that both ends of the winding carrier always protrude a bit from the winding in the wound winding carrier. In such a protruding piece of the winding carrier, e.g. a radially protruding end ring.

Wenn nun derartige Wickelträger z.B. zum Färben axial übereinandergesetzt werden, so kommen zunächst nur die Wickelträger aneinander zur Anlage, während zwischen den Wickeln benachbarter Träger ein beträchtlicher Ringraum freibleibt. Wenn also aus den Wickeln eine homogene Garn­säule gebildet werden soll, dann müssen zunächst einmal die vorstehenden Enden der Wickelträger gegeneinander ver­schoben werden, wobei es zu Verlagerungen des Garns auf dem Wickelträger und zum Einpressen der Wickelträgerenden in die Wickel kommt. Störungen des vorgegebenen Garnverlaufs sind die Folge, die sich z.B. beim Abspulen nachteilig aus­wirken können.If such winding carriers now e.g. are placed axially one above the other for dyeing, so initially only the winding carriers come into contact with one another, while a considerable annular space remains free between the windings of adjacent carriers. If a homogeneous column of yarn is to be formed from the bobbins, then the protruding ends of the bobbin must first be shifted against each other, with the yarn being displaced on the bobbin and the ends of the bobbin being pressed into the bobbin. Disturbances in the specified course of yarn are the result, e.g. can have a negative impact on unwinding.

Erst wenn auf diese Weise die über die Wickel vorstehenden Stücke der Wickelträger von den Wickeln überlagert sind, kommen die Wickel aneinander zur Anlage. Folglich bewirkt erst dann die weitere Pressung eine Homogenisierung der zu einer Säule zusammengestellten Garnwickel.Only when the pieces of the winding carrier projecting over the windings are overlaid by the windings in this way do the windings come into contact with one another. Only then does the further pressing bring about a homogenization of the yarn packages assembled into a column.

Es sind ferner bereits Wickelträger bekannt (DE-PS 851 946), die einen durchbrochenen Hülsenmantel und an dessen Enden im wesentlichen in der Hülsenmantelfläche angeordnete Vorsprünge und Lücken aufweisen, welche geeignet sind, zahnartig in entsprechende, an den Enden benachbarter gleichachsiger Wickelträger vorgesehene Lücken und Vor­sprünge axial verschiebbar einzugreifen. Nachteilig ist bei diesen bekannten Wickelträgern, daß sie nicht aneinander axial geführt sind und daß sie zudem eine sichere Unter­bringung einer Fadenreserve nicht gestatten.There are also already known winding carriers (DE-PS 851 946), which have a perforated sleeve jacket and at the ends of the projections and gaps arranged essentially in the sleeve jacket surface, which are suitable, tooth-like in corresponding gaps provided at the ends of adjacent coaxial carrier and To engage projections axially slidably. The disadvantage of these known winding carriers is that they are not axially guided against one another and that they also do not permit secure accommodation of a thread reserve.

Es ist ferner ein Wickelträger bekannt (EP-OS 201 826), bei dem ein oberer Endring mit einem axial vorstehenden Bund versehen ist, der in dem unteren Endring eines axial be­nachbarten, gleich ausgebildeten Wickelträgers eingesteckt werden kann und dabei Raum für eine auf dem Bund vorgese­hene Fadenreserve läßt, die somit geschützt untergebracht ist. Das Maß, um das der Bund eines Wickelträgers in einen anderen eingesteckt werden kann, wird durch Schultern und Ansätze begrenzt. An seinem dem Bund eines benachbarten Wickelträgers übergreifenden Ende ist eine Anlaufringfläche vorgesehen, die in Bezug auf die Tragfläche nach radial außen versetzt ist. Nachteilig ist dabei, daß beim Aufein­andersetzen bespulter Wickelträger zwischen deren Wickeln zunächst Ringspalte verbleiben, die beim Komprimieren unter Garnverlagerung geschlossen werden müssen.There is also a winding carrier known (EP-OS 201 826), in which an upper end ring is provided with an axially projecting collar, which can be inserted into the lower end ring of an axially adjacent, identically designed winding carrier and thereby space for one on the collar provided thread reserve, which is thus housed protected. The extent to which the waistband of one winding carrier can be inserted into another is limited by shoulders and shoulders. At its end which overlaps the collar of an adjacent winding support, a thrust ring surface is provided which is offset radially outward with respect to the support surface. The disadvantage here is that when winding wound bobbins are placed one on top of the other, annular gaps remain between their windings, which have to be closed when compressing with yarn displacement.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, einen Wickelträger der eingangs erwähnten Art so auszubil­den, daß eine Fadenreserve sicher untergebracht werden kann und daß unmittelbar nach dem axialen Übereinandersetzen solcher Wickelträger die darauf befindlichen Wickel anein­ander zur Anlage kommen, so daß im Falle eines axialen Pressens nicht zunächst allein die Wickelträger verschoben werden müssen, sondern daß stets gemeinsam mit den Wickel­trägern auch die Wickel komprimiert werden.The object of the present invention is to provide a bobbin of the type mentioned in such a way that a thread reserve can be safely accommodated and that immediately after such bobbins are axially stacked, the bobbins thereon come into contact with one another, so that in the case of axial pressing not only the winding carriers have to be moved first, but that the windings are always compressed together with the winding carriers.

Diese Aufgabe wird erfindungsgemäß bei einem Wickelträger der eingangs erwähnten Art dadurch gelöst, daß an dem einen Ende des Körpers ein über die Verzahnung hinaus axial vor­stehender Bund vorgesehen ist, dessen Außenfläche in Bezug auf diese Verzahnung nach radial innen versetzt ist, und daß an dem anderen Ende des Körpers eine den Außenabmessun­gen des Bundes angepaßte Aufnahme vorgesehen ist, deren Außenfläche bezüglich der an diesem Ende vorgesehenen Ver­zahnung nach radial innen versetzt ist.This object is achieved according to the invention in a winding support of the type mentioned in the introduction in that at one end of the body there is a collar projecting axially beyond the toothing, the outer surface of which is offset radially inward with respect to this toothing, and in that on the other At the end of the body a receptacle adapted to the outer dimensions of the collar is provided, the outer surface of which is offset radially inward with respect to the toothing provided at this end.

Bei diesem Wickelträger kann die Bespulung bis in den Be­reich der beiden Verzahnungen durchgeführt werden und diese z.B. um 50% ihrer axialen Erstreckung überdecken. Somit verbleibt dann für die Verzahnungen noch ein Überstand ge­genüber dem Wickel von etwa 2 bis 4 Millimetern. Werden derartige bespulte Wickelträger axial übereinandergesetzt, so bewirken die Verzahnungen eine gegenseitige Zentrierung. Darüber hinaus kommen die Stirnflächen der benachbarten Wickel unmittelbar aneinander zu liegen. Auf diese Weise wird Lager- und Transportraum eingespart. Ferner wird si­chergestellt, daß im Falle eines axialen Zusammendrückens zugleich dieser Druck auch zwischen den Wickeln wirksam wird, so daß Relativbewegungen zwischen den Wickeln einer­seits und den Wickelträgern andererseits praktisch ausge­schaltet werden.With this winding carrier, the winding can be carried out up to and in the area of the two toothings cover, for example, 50% of their axial extent. This leaves a gap of about 2 to 4 millimeters for the gears. If such wound bobbin carriers are placed axially one above the other, the toothings bring about mutual centering. In addition, the end faces of the adjacent windings come to lie directly against one another. This saves storage and transport space. Furthermore, it is ensured that, in the event of an axial compression, this pressure also becomes effective between the windings, so that relative movements between the windings on the one hand and the winding carriers on the other hand are practically eliminated.

Die beiden Verzahnungen eines Wickelträgers sind zwar an­einander angepaßt, um ein Ineinderführen zu ermöglichen, können aber in ihren Konturen durchaus voneinander abwei­chen.The two toothings of a winding carrier are adapted to one another to enable insertion into one another, but their contours may well differ from one another.

Die Tragfläche des erfindungsgemäßen Wickelträgers kann zylindrisch, konisch oder anderweitig ausgebildet sein und in die Außenflächen der Verzahnungen stufenlos übergehen. Es liegt keinerlei Einschränkung hinsichtlich der anzuwen­denden Wickelart vor.The supporting surface of the winding support according to the invention can be cylindrical, conical or otherwise and can be continuously merged into the outer surfaces of the toothings. There is no restriction regarding the type of wrapping to be used.

Der Bund verbessert die Führung zwischen zwei axial benach­barten Wickelträgern. Er kann ferner zur Unterbringung ei­ner Fadenreserve benutzt werden.The collar improves the guidance between two axially adjacent winding carriers. It can also be used to accommodate a thread reserve.

Der erfindungsgemäße Wickelträger kann ferner so ausgebil­det sein, daß die Aufnahme eine Anschlagschulter für das Ende des Bundes eines axial benachbarten Wickelträgers auf­weist. Diese Anschlagschulter definiert genau das Maß, bis zu dem zwei benachbarte Wickelträger ineinander ohne Pres­sung eingeführt werden können.The winding support according to the invention can also be designed so that the receptacle has a stop shoulder for the end of the collar of an axially adjacent winding support. This stop shoulder defines exactly the extent to which two adjacent winding carriers can be inserted into one another without pressing.

Der erfindungsgemäße Wickelträger kann ferner so ausgebil­det sein, daß auf dem Bund eine Fadenreservenut vorgesehen ist. Auf diese Weise kann die Plazierung einer Fadenreserve weiter gesichert werden.The winding support according to the invention can also be designed so that a thread reserve groove is provided on the collar. In this way, the placement of a thread reserve be further secured.

Der erfindungsgemäße Wickelträger kann ferner so ausgebi-1­det sein, daß die beiden Verzahnungen wellenförmige Zahn­profile haben. Bei Verwendung eines solchen Zahnprofils führen sich die Verzahnungen benachbarter Wickelträger selbsttätig ineinander ein.The winding carrier according to the invention can also be designed in such a way that the two toothings have undulating tooth profiles. When using such a tooth profile, the teeth of adjacent winding carriers automatically lead into each other.

Der erfindungsgemäße Wickelträger kann ferner so ausgebil­det sein, daß die beiden Verzahnungen sägezahnartige Zahn­profile haben.The winding support according to the invention can also be designed so that the two toothings have sawtooth-like tooth profiles.

Der erfindungsgemäße Wickelträger kann ferner so ausgebi-1­det sein, daß die beiden Verzahnungen im wesentlichen rechteckige Zahnprofile haben.The winding carrier according to the invention can also be designed such that the two toothings have essentially rectangular tooth profiles.

Der erfindungsgemäße Wickelträger kann ferner so ausgebil­det sein, daß die Zähne zumindest einer Verzahnung minde­stens einen nur einen Teil des jeweiligen Zahnprofils aus­machenden Auflageabschnitt zur Anlage an den Zähnen eines axial benachbarten gleichen Wickelträgers haben. Dies ist insbesondere dann vorteilhaft, wenn das Einstecken benach­barter Wickelträger durch den Zahneingriff, nicht also durch eine Anschlagschulter, begrenzt wird. Es wird auch dann ein Verklemmen ausgeschlossen.The winding carrier according to the invention can also be designed such that the teeth of at least one toothing have at least one support section which only makes up part of the respective tooth profile for contacting the teeth of an axially adjacent identical winding carrier. This is particularly advantageous if the insertion of adjacent winding carriers is limited by the tooth engagement, not by a stop shoulder. A jamming is then also excluded.

Der in Fig. 1 dargestellte Wickelträger hat einen rotationssymmetrischen Körper 1, der lediglich schematisch abgebildet ist und dessen Ausbildung nicht Gegenstand der Erfindung ist. Der Körper 1 kann ein- oder mehrteilig sein und dabei eine zylindrische, konische oder anderweitige Form haben.The winding support shown in Fig. 1 has a rotationally symmetrical body 1, which is only shown schematically and the formation of which is not the subject of the invention. The body 1 can be in one or more parts and have a cylindrical, conical or other shape.

Der Körper 1 bildet eine Tragfläche 2, welche durch Stege oder durch eine vorzugsweise perforierte Mantelwand gebil­det sein kann.The body 1 forms an airfoil 2, which can be formed by webs or by a preferably perforated jacket wall.

An die Tragfläche 2 schließen sich eine untere Verzahnung 3 sowie eine obere Verzahnung 4 an. Beide Verzahnungen 3,4 verlaufen ringförmig und haben äquidistant verteilte Zähne 5,6, die jeweils axial vorstehen. Die radial außen liegen­den Flächen der Zähne 5,6 schließen sich stufenlos an die Tragfläche 2 an.A lower toothing 3 and an upper toothing 4 are connected to the wing 2. Both toothings 3, 4 are ring-shaped and have equidistantly distributed teeth 5, 6, each of which protrude axially. The radially outer surfaces of the teeth 5, 6 connect continuously to the wing 2.

Die Außendurchmesser der beiden ringförmigen Verzahnungen 3,4 sind untereinander gleich.The outer diameters of the two annular toothings 3, 4 are identical to one another.

Im Bereich der oberen Verzahnung 4 ist ein Bund 7 vorgese­hen, der in axialer Richtung über die obere Verzahnung 4 hinaus vorsteht. Der Bund 7 hat eine Außenfläche 8, die re­lativ zur oberen Verzahnung 4 nach radial innen versetzt ist. Die Zähne 6 können somit als auf der Außenfläche 8 des Bundes 7 liegend verstanden werden.In the area of the upper toothing 4, a collar 7 is provided which projects beyond the upper toothing 4 in the axial direction. The collar 7 has an outer surface 8 which is offset radially inwards relative to the upper toothing 4. The teeth 6 can thus be understood as lying on the outer surface 8 of the collar 7.

Im Bereich der unteren Verzahnung 3 ist eine Aufnahme 9 vorgesehen, deren Durchmesser dem Außendurchmesser des Bun­des 7 angepaßt ist. Die Aufnahme 9 bildet eine Anschlag­schulter 10.In the area of the lower toothing 3, a receptacle 9 is provided, the diameter of which is adapted to the outer diameter of the collar 7. The receptacle 9 forms a stop shoulder 10.

Bei der Ausführungsform nach Fig. 1 haben beide Verzahnun­gen 3,4 ein wellenförmiges Profil.In the embodiment according to FIG. 1, both toothings 3, 4 have an undulating profile.

Fig. 2 zeigt drei Wickelträger der in Fig. 1 beschriebenen Art mit Wickeln 11, die zu einer Garnsäule 12 zusammenge­stellt sind. Fig. 2 macht deutlich, daß die Stirnflächen der Wickel 11 jeweils im mittleren Bereich der beiden Ver­zahnungen 3,4 liegen. Aufgrund der Anpassung zwischen der unteren Verzahnung 3 und der oberen Verzahnung 4 können derartige Wickelträger axial übereinander gesetzt werden, wobei die Zähne 5,6 miteinander in Eingriff kommen und der Bund 7 in die Aufnahme 9 eingreift, wo er schließlich an der Anschlagschulter 10 anschlägt. Wenn nun nach Fig. 2 zusammengestellte Wickel 11 axial komprimiert werden sol­len, dann führt ein Pressen sogleich zu einem Zusammen­drücken der Wickelträger und der Wickel 11, da schon nach dem Aufeinandersetzen der Wickelträger praktisch kein Spalt zwischen den Wickeln 11 vorliegt.FIG. 2 shows three winding carriers of the type described in FIG. 1 with windings 11, which are assembled into a yarn column 12. Fig. 2 makes it clear that the end faces of the winding 11 are each in the central region of the two toothings 3, 4. Because of the adaptation between the lower toothing 3 and the upper toothing 4, such winding carriers can be placed axially one above the other, the teeth 5, 6 engaging with one another and the collar 7 engaging in the receptacle 9, where it finally strikes the stop shoulder 10. If the coils 11 assembled according to FIG. 2 are to be axially compressed, then pressing immediately results in the winding carriers and the coils 11 being compressed, since there is practically no gap between the coils 11 after the winding carriers have been placed on top of one another.

Fig. 3 verdeutlicht in größerem Maßstab das Ineinandergrei­fen benachbarter Wickelträger.Fig. 3 illustrates on a larger scale the interlocking of adjacent winding carriers.

Der Durchmesser der Außenfläche 8 des über die Zähne 6 vor­stehenden Bundes 7 ist kleiner als der Innendurchmesser der Aufnahme 9, so daß auf der Außenfläche 8 geschützt eine Fa­denreserve untergebracht werden kann. Die Unterbringung der Fadenreserve kann dadurch weiter gesichert werden, daß in der Außenfläche 8 eine Fadenreservenut vorgesehen ist, wie sie in Fig.3 gestrichelt angedeutet ist.The diameter of the outer surface 8 of the collar 7 projecting beyond the teeth 6 is smaller than the inner diameter of the receptacle 9, so that a thread reserve can be accommodated on the outer surface 8 in a protected manner. The placement of the Thread reserve can be further secured in that a thread reserve groove is provided in the outer surface 8, as indicated by dashed lines in FIG.

In den Figuren 4 bis 7 sind Zahnprofilformen dargestellt, die u.a. bei dem erfindungsgemäßen Wickelträger Verwendung finden können. Bei den Zahnprofilen nach den Figuren 4 und 5 handelt es sich um sägezahnartige Profile, die sich le­diglich in der Ausbildung ihrer Spitzen unterscheiden.In the figures 4 to 7 tooth profile shapes are shown, which among other things. can be used in the winding carrier according to the invention. The tooth profiles according to FIGS. 4 and 5 are sawtooth-like profiles that only differ in the design of their tips.

Fig. 6 zeigt ein Zahnprofil, das rechteckig ausgebildet ist.Fig. 6 shows a tooth profile which is rectangular.

Die Figuren 4 bis 6 machen deutlich, daß hier die Begren­zung der Einstecktiefe nicht durch die Zähne 5,6 erfolgt, sondern durch einen anderweitigen Anschlag, z.B. die An­schlagschulter 10 gemäß den Figuren 1 und 3.Figures 4 to 6 make it clear that here the insertion depth is not limited by the teeth 5, 6, but by another stop, e.g. the stop shoulder 10 according to FIGS. 1 and 3.

Fig. 7 zeigt zwei voneinander abweichende Verzahnungen 13,14. Die Verzahnung 13 ist wellenförmig profiliert. Die Verzahnung 14 hat Zähne 15, welche Auflageabschnitte 16 aufweisen, die nur einen Teil des gesamten Zahnprofils aus­machen und definieren, wie weit die Verzahnungen 13,14 in­einandergeführt werden können.7 shows two mutually different toothings 13, 14. The toothing 13 is profiled in a wave shape. The toothing 14 has teeth 15 which have support sections 16 which only make up part of the entire tooth profile and define how far the toothings 13, 14 can be guided into one another.

Die Zähne aller beschriebenen Ausführungsformen sind insbe­sondere an ihren vorderen Enden gerundet, um jeweils den auf dem anderen Wickelträger befindlichen Wickel 11 zu un­terfahren, um Beschädigungen des Garns zu vermeiden.The teeth of all the described embodiments are rounded in particular at their front ends, in order to pass under the winding 11 located on the other winding support in order to avoid damage to the yarn.
