Abstract

In a flanged reel having an essentially cylindrical casing (1) which forms a winding surface and which adjoins at one end a radially outward-projecting flange (3) and at its other end a concentric annular collar (9) of reduced diameter, and having a supporting element (11) arranged within the casing (1) and possessing a central guide tube (12), the latter is made elastically flexible in the radial direction in an edge region (16) facing the end (foot end) equipped with the flange (3). Such a flexibility can reliably guarantee that the edge region (16) will bear against a receiving mandrel, with the result that the concentric running properties and load absorption are improved. <IMAGE>

Description

Die Erfindung betrifft eine Flanschenspule aus Kunststoff, insbesondere zur Aufnahme von Glasfasergarnen, mit einem im wesentlichen zylindrischen, eine Wickelfläche bildenden Mantel, an den sich an seinem einen Ende ein radial nach außen vorstehender Flansch und an seinem anderen Ende ein konzentrischer Ringbund mit reduziertem Durchmesser an­schließt, und mit einem innerhalb des Mantels angeordneten Stützelement, das eine zentrale Führungshülse aufweist.The invention relates to a flange spool made of plastic, in particular for receiving glass fiber yarns, with an essentially cylindrical jacket forming a winding surface, to which at one end a radially outwardly projecting flange and at the other end a concentric ring collar with a reduced diameter adjoins , and with a support element arranged within the jacket and having a central guide sleeve.

Bei den bekannten Flanschenspulen dieser Art ist das Stütz­element ein separat hergestelltes Element, das anschließend in der Flanschenspule plaziert wird. Das Stützelement ist dabei mittels einer Schnappverbindung oder durch Klebung mit dem Mantel der Flanschenspule verbunden. Es hat eine starre Führungshülse, in die das obere Ende eines Auf­nahmedorns zentrierend eingreift. Eine weitere Zentrierung erfolgt über einen Aufnahmering im Flanschenbereich.In the known flange coils of this type, the support element is a separately manufactured element which is then placed in the flange coil. The support element is connected to the jacket of the flange coil by means of a snap connection or by gluing. It has a rigid guide sleeve in which the upper end of a mandrel engages. A further centering takes place via a receiving ring in the flange area.

Es wird nun angestrebt, die von einer solchen Flanschen­spule aufzunehmende Garnmenge beträchtlich zu erhöhen und darüber hinaus auch die beim Spulvorgang angewandten Dreh­zahlen zu steigern.The aim now is to considerably increase the amount of yarn to be taken up by such a flange bobbin and also to increase the speeds used in the winding process.

Die Erhöhung der von einer Flanschenspule aufzunehmenden Garnmenge hat zur Folge, daß bisher vonhand ausgeführte Um­steckvorgänge automatisiert und zukünftig maschinell vorge­nommen werden müssen. Daraus ergeben sich bei Spulen der hier betroffenen Art Schwierigkeiten hinsichtlich der Art und der Größe der aufzunehmenden Kräfte. Die angestrebte Erhöhung der Drehszahlen führt zu gesteigerten Forderungen hinsichtlich der Zentrierung der Flanschenspule auf dem Aufnahmedorn.The increase in the amount of yarn to be picked up by a flange bobbin has the consequence that changing operations previously carried out by hand must be automated and in the future carried out mechanically. In the case of coils of the type concerned here, this results in difficulties with regard to the type and the size of the forces to be absorbed. The desired increase in engine speeds leads to increased demands with regard to the centering of the flange coil on the arbor.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Flanschenspule der eingangs erwähnten Art derart aus­zubilden, daß sie für ein maschinelles Handling auch bei erhöhten Garnmengen und Drehzahlen geeignet ist.The object of the present invention is to design a flange spool of the type mentioned at the outset in such a way that it is suitable for mechanical handling even at increased yarn quantities and speeds.

Diese Aufgabe wird erfindungsgemäß bei einer Flanschenspule der eingangs erwähnten Art dadurch gelöst, daß die Füh­rungshülse in einem dem mit dem Flansch versehenen Ende (Fußende) zugewandten Randbereich in radialer Richtung ela­stisch nachgiebig ausgebildet ist. Durch eine solche Nachgiebigkeit kann ein Anliegen des Randbereiches an dem Aufnahmedorn zuverlässig sichergestellt werden, wodurch die Rundlaufeigenschaften und die Lastaufnahme verbessert wer­den.This object is achieved according to the invention in the case of a flange coil of the type mentioned at the outset in that the guide sleeve is designed to be elastically resilient in the radial direction in an edge region facing the end (foot end) provided with the flange. Such flexibility makes it possible to reliably ensure that the edge area bears against the arbor, which improves the concentricity and load carrying capacity.

Die erfindungsgemäße Flanschenspule kann ferner so ausge­bildet sein, daß im Randbereich der Führungshülse über de­ren Innenfläche nach radial innen vorstehende Ansätze vor­gesehen sind. Die Ansätze sind dabei so plaziert und be­messen, daß es immer zu einem Angreifen der Ansätze an der Umfangsfläche des Aufnahmedorns kommt. Erforderlichenfalls wird dabei der Randbereich nach außen verformt. Jedenfalls ergibt sich ein straffer Sitz der Führungshülse auf dem Aufnahmedorn.The flange coil according to the invention can also be designed in such a way that in the edge region of the guide sleeve over the inner surface there are projections projecting radially inwards. The lugs are placed and dimensioned so that there is always an attack on the lugs on the peripheral surface of the mandrel. If necessary, the edge area is deformed outwards. In any case, there is a tight fit of the guide sleeve on the mandrel.

Die erfindungsgemäße Flanschenspule kann ferner so ausge­bildet sein, daß die Ansätze als Nocken ausgebildet sind.The flange coil according to the invention can also be designed so that the lugs are designed as cams.

Die erfindungsgemäße Flanschenspule kann ferner so ausge­bildet sein, daß der Randbereich durch von seinem freien Ende ausgehende Schlitze in mehrere Segmente aufgeteilt ist. Diese Segmentbildung erleichtert das Ausweichen des Randbereichs nach außen, sofern dies beim Einführen des Aufnahmedorns in die Führungshülse erforderlich wird.The flange coil according to the invention can also be designed such that the edge region is divided into several segments by slots extending from its free end. This segment formation makes it easier for the edge region to deflect outward, provided this becomes necessary when the mandrel is inserted into the guide sleeve.

Die erfindungsgemäße Flanschenspule kann ferner so ausge­bildet sein, daß der Randbereich ein in Umfangsrichtung wellenförmiges Profil hat. Daraus können sich hinsichtlich der Entformbarkeit der Herstellung Vorteile ergeben.The flange coil according to the invention can also be designed so that the edge region has a corrugated profile in the circumferential direction. This can result in advantages with regard to the demoldability of the production.

Die erfindungsgemäße Flanschenspule kann ferner so ausgebildet sein, daß die Wandstärke der Führungshülse im Randbereich reduziert ist.The flange coil according to the invention can also be designed so that the wall thickness of the guide sleeve is reduced in the edge region.

Die erfindungsgemäße Flanschenspule kann ferner so ausge­bildet sein, daß die Führungshülse, in ihrem Randbereich mit nach radial innen wirksamen Federelementen versehen ist. Dabei kann der Randbereich der Führungshülse starr bleiben oder sich ebenfalls verformen.The flange coil according to the invention can also be designed such that the guide sleeve is provided in its edge region with spring elements acting radially inwards. The edge area of the guide sleeve can remain rigid or can also deform.

Die erfindungsgemäße Flanschenspule kann ferner so ausge­bildet sein, daß der Randbereich durch Ausschnitte zum Teil umgrenzte Zonen aufweist, in denen nach radial innen vor­stehende Nocken angeordnet sind. Dabei verformen sich le­diglich die die Nocken tragenden Zonen nach radial außen.The flange coil according to the invention can also be designed such that the edge region has partially delimited zones by cutouts, in which cams projecting radially inward are arranged. Only the zones carrying the cams deform radially outward.

Die erfindungsgemäße Flanschenspule kann so ausgebildet sein, daß sie im Bereich des Flansches einen Aufnahmering aufweist, der wie der Randbereich der Führungshülse ausge­bildet ist. Der Aufnahmedorn wird üblicherweise im Stütze­lement sowie im Bereich des Flansches geführt. Demzufolge können alle Merkmale, die zu einem straffen, optimal zen­trierten Sitz des Aufnahmedorns in der Führungshülse füh­ren, auch an dem Aufnahmering im Bereich des Flansches be­nutzt werden.The flange coil according to the invention can be designed in such a way that it has a receiving ring in the region of the flange, which is designed like the edge region of the guide sleeve. The mandrel is usually guided in the support element and in the area of the flange. Accordingly, all features that lead to a tight, optimally centered fit of the holding mandrel in the guide sleeve can also be used on the holding ring in the region of the flange.

Die erfindungsgemäße Flanschenspule kann so ausgebildet sein, daß die Führungshülse des Stützelements durch radial angeordnete Stege gehalten ist, welche in dem Randbereich einen Spalt zur Außenfläche der Führungshülse frei lassen.The flange coil according to the invention can be designed such that the guide sleeve of the support element is held by radially arranged webs, which leave a gap in the edge region to the outer surface of the guide sleeve.

Die erfindungsgemäße Flanschenspule kann so ausgebildet sein, daß das Stützelement ein homogenes, einstückig mit der Flanschenspule gespritztes Bauteil ist, das sich unmit­ telbar an das mit dem Ringbund versehende Ende der Flan­schenspule anschließt, und daß die Führungshülse allein über axial gerichtete Stege an den Mantel angeschlossen ist.The flange coil according to the invention can be designed in such a way that the support element is a homogeneous component which is injection-molded in one piece with the flange coil and which is unrelated connects to the end of the flange coil provided with the collar, and that the guide sleeve is connected to the jacket solely via axially directed webs.

Diese Ausbildung des Stützelements erlaubt es bei einfacher Herstellung zum automatisierten Handling der bespulten Flanschenspule einen durch den Ringbund hindurch eingeführ­ten Tragdorn aufzunehmen und die von diesem auf gewandten Kräfte auf den Mantel der Spule zuverlässig zu übertragen. Dabei können insbesondere aufgrund der einstückigen Ausbil­dung enge Toleranzen beim Innendurchmesser der Führungs­hülse eingehalten werden, welche die Zentrierung der Flan­schenspule auf einem von dem Flanschende her eingeführten Aufnahmedorn und damit die Rundlaufeigenschaften erheblich verbessern.This design of the support element makes it possible, in the case of simple manufacture, for automated handling of the spooled flange coil to accommodate a support mandrel inserted through the annular collar and to reliably transmit the forces applied by it to the jacket of the coil. In particular, due to the one-piece design, tight tolerances in the inner diameter of the guide sleeve can be maintained, which considerably improve the centering of the flange coil on a mandrel inserted from the flange end and thus the concentricity properties.

Die erfindungsgemäße Flanschenspule kann ferner so ausge­bildet sein, daß die dem mit dem Flansch versehenen Ende (Fußende) zugewandten Kanten der Stege in Richtung auf das mit dem Ringbund versehene Ende (Kopfende) zur Führungs­hülse hin geneigt verlaufen. Dadurch wird das Einführen des Aufnahmedorns in die Führungshülse verbessert.The flange coil according to the invention can also be designed such that the edges of the webs facing the flange-provided end (foot end) are inclined in the direction of the ring-collar end (head end) towards the guide sleeve. This improves the insertion of the mandrel into the guide sleeve.

Die erfindungsgemäße Fianschenspule kann ferner so ausge­bildet sein, daß die dem mit dem Ringbund versehenen Ende Kopfende) zugewandten Kanten der Stege in Richtung auf das mit dem Flansch versehene Ende (Fußende) zur Führungshülse hin geneigt verlaufen. Auf diese Weise kann die Einführung eines durch den Ringbund hindurchreichenden Tragdorns oder dergleichen vereinfacht werden.The Fianschenspule according to the invention can also be designed so that the edges of the webs facing the end provided with the annular collar (head end) run inclined towards the end provided with the flange (foot end) towards the guide sleeve. In this way, the introduction of a supporting mandrel or the like which extends through the annular collar can be simplified.

Die erfindungsgemäße Flanschenspule kann schließlich so ausgebildet sein, daß das Stützelement in die Flanschen­spule eingeklebt oder mittels einer Schnappverbindung in diese eingesetzt ist.The flange coil according to the invention can finally be designed such that the support element is glued into the flange coil or inserted into it by means of a snap connection.

Die hier betroffene Flanschenspule besteht aus Kunststoff. Die anhand der Fig. 1 bis 3 beschriebene Ausführungsform hat einen zylindrischen Mantel 1, der mit Durchbrechungen 2 versehen ist. An ihrem einen Ende, das nachfogend als Fußende bezeichnet wird, weist die Flanschenspule einen nach radial außen vorstehenden Flansch 3 auf, der einen ra­dial verlaufenden Scheibenteil 4 hat, von dem in Fig.1 nach unten hin drei konzentrische Ringe 5, 6, 7 ausgehen. Der Ring 5 fluchtet dabei mit der Zylinderfläche des Mantels 1. Der am weitesten radial außen liegende Ring 7 hat auf sei­ner Außenfläche eine Fadenreservenut 8.The flange coil affected here is made of plastic. The embodiment described with reference to FIGS. 1 to 3 has a cylindrical jacket 1 which is provided with openings 2. At one end, which is referred to as the foot end, the flange coil has a radially outwardly projecting flange 3, which has a radially extending disk part 4, from which three concentric rings 5, 6, 7 extend downwards in FIG . The ring 5 is aligned with the cylindrical surface of the jacket 1. The most radially outer ring 7 has a thread reserve groove 8 on its outer surface.

An den Mantel 1 schließt sich an dem anderen Ende der Flan­schenspule, das nachstehend als Kopfende bezeichnet wird, ein konzentrischer Ringbund 9 an, der in seinem Durchmesser gegenüber dem des Mantels 1 stark reduziert ist. Am Über­gang zwischen dem Mantel 1 und dem Ringbund 9 ist eine Ringschulter 10 vorgesehen. Innerhalb des Mantels 1 ist ein Stützelement 11 angeordnet, das eine konzentrische Füh­rungshülse 12 hat, die über axiale und dabei radial gerich­tete geschlossene Stege 13 an dem Mantel 1 abgestützt ist. Die Stege 13 schließen sich an die Innenfläche der Ring­schulter 10 unmittelbar an. Das Stützelement 11 ist mit dem übrigen Teil der Flanschenspule demnach homogen und ein­stückig verbunden.The jacket 1 is adjoined at the other end of the flange coil, which is referred to below as the head end, by a concentric annular collar 9, whose diameter is greatly reduced compared to that of the jacket 1. At the transition between the jacket 1 and the collar 9 an annular shoulder 10 is provided. A support element 11 is arranged inside the casing 1, which has a concentric guide sleeve 12 which is supported on the casing 1 by means of axially and radially directed closed webs 13. The webs 13 directly adjoin the inner surface of the annular shoulder 10. The support element 11 is therefore homogeneously and integrally connected to the remaining part of the flange coil.

Die Stege 13 haben an ihrem dem Fußende zugewandten Ende Kanten 14, die ausgehend vom Mantel 1 nach radial innen verlaufen und dabei zum Kopfende hin geneigt sind. Diese Kanten 14 fluchten mit dem dem Fußende zugewandten Rand 15 der Führungshülse 12.At their end facing the foot end, the webs 13 have edges 14 which, starting from the casing 1, extend radially inwards and are inclined towards the head end. These edges 14 are aligned with the edge 15 of the guide sleeve 12 facing the foot end.

Die Führungshülse 12 hat einen dem Fußende zugewandten Randbereich 16, in dem die Stege 13 einen Abstand zur Außenfläche der Führungshülse 12 frei lassen, sodaß hier je­der Steg 13 einen Schlitz 17 bildet.The guide sleeve 12 has an edge region 16 facing the foot end, in which the webs 13 leave a clearance to the outer surface of the guide sleeve 12, so that each web 13 forms a slot 17 here.

Von dem inneren Rand der Ringschulter 10 gehen Kanten 18 der Stege 13 aus, welche mit dem oberen Rand 19 der Füh­rungshülse 12 fluchten und dabei nach radial innen gerich­tet sind.Edges 18 of the webs 13 extend from the inner edge of the annular shoulder 10, which are aligned with the upper edge 19 of the guide sleeve 12 and are directed radially inward.

Die in den Fig. 12,13 dargestellte Ausführungsform unter­scheidet sich von der zuvor beschriebenen lediglich da­durch, daß hier ein Stützelement 11′ mit Abstand vom Kopfende 9 der Flanschenspule in diese eingesetszt ist, welches zunächst als als Bauteil separat hergestellt und dann in die Flanschenspule eingesetzt wurde. Die Festlegung dieses Stützelements in der Flanschenspule erfolgt durch eine Kleb- oder eine Schnappverbindung. Insbesondere hin­sichtlich der Ausbildung des Randbereichs 16 kann das Stützelement 11′ mit dem zuvor beschriebenen Stützelement 11 voll übereinstimmen. Die nachfolgend beschriebenen Aus­führungsformen des Randbereichs können folglich bei Stütz­elementen Anwendung finden, die einstückig mit einer Flan­schenspule oder separat hergestellt sind.The embodiment shown in Fig. 12,13 differs from the previously described only in that here a support element 11 'is inserted at a distance from the head end 9 of the flange coil, which is initially manufactured as a component and then inserted into the flange coil has been. This support element is fixed in the flange coil by an adhesive or snap connection. In particular with regard to the formation of the edge region 16, this can be done Support element 11 'fully match the previously described support element 11. The embodiments of the edge region described below can consequently be used in support elements which are produced in one piece with a flange coil or separately.

Anhand der Fig. 4 und 5 wird eine Ausführungsform beschrie­ben, die sich allein durch eine besondere Ausgestaltung des Randbereichs 16 der Führungshülse 12 auszeichnet. Der Rand­bereich 16 ist dabei durch Schlitze 25 in vier Segmente 26 unterteilt, welche jeweils einen konisch nach innen sich verjüngenden Rand 27 und einen Ansatz 28 haben, der über die Innenfläche 29 der Führungshülse 12 hinaus nach radial innen vorsteht. Der Ansatz 28 ist wulstartig ausgebildet.An embodiment is described with reference to FIGS. 4 and 5, which is characterized solely by a special configuration of the edge region 16 of the guide sleeve 12. The edge region 16 is divided by slots 25 into four segments 26, each of which has a conically tapering edge 27 and a shoulder 28 which projects radially inward beyond the inner surface 29 of the guide sleeve 12. The approach 28 is bead-like.

Bei der Ausführungsrorm nach den Fig. 6, 7 sind im Randbe­reich 16 der Führungshüise 12 auf deren Innenfläche 29 tropfenartige Ansätze 30 vorgesehen, die nach radial innen vorstehen.6, 7 in the edge region 16 of the guide sleeve 12 on the inner surface 29 drop-like projections 30 are provided which protrude radially inwards.

Bei der Ausführungsform nach den Fig. 8, 9 ist im Randbe­reich 16 der Führungshülse 12 die Wandstärke reduziert. Das Profil dieses Randbereichs 16 stellt sich dabei in Umfangs­richtung wellenförmig dar. Es wird durch diese Ausbildung plastisch verformbar in radialer Richtung.In the embodiment according to FIGS. 8, 9, the wall thickness is reduced in the edge region 16 of the guide sleeve 12. The profile of this edge region 16 is undulating in the circumferential direction. This configuration makes it plastically deformable in the radial direction.

Im Randbereich 16 der Ausführungsform nach Fig. 10, 11 sind durch jeweils zwei axial verlaufende Langlöcher 31 verform­bare Zonen 32 geschaffen, die jeweils einen nach radial in­nen über die Führungsfläche 29 der Führungshülse 12 hinaus nach radial innen vorstehenden Ansatz 33 tragen.In the edge region 16 of the embodiment according to FIGS. 10, 11, zones 32 which can be deformed are each created by two axially extending elongated holes 31, each of which carries a projection 33 projecting radially inward beyond the guide surface 29 of the guide sleeve 12 and radially inwardly.

Bei der Ausführungsform nach den Fig. 10, 11 ist eine Auf­weitung des Randbereichs 16 insgesamt nicht erforderlich. Folglich sind bei dieser Ausführungsform zwischen den Ste­gen 13 und dem Randbereich 16 keine Schlitze vorgesehen.In the embodiment according to FIGS. 10, 11, widening of the edge region 16 is not required overall. Consequently, no slots are provided between the webs 13 and the edge region 16 in this embodiment.

Die besondere Ausgestaltung des Randbereichs 16 in den ver­schiedenen Ausführungsformen der erfindungsgemäßen Flan­ schenspule dient dazu, hier eine straffe Führung auf dem oberen Ende eines nicht dargestellten Aufnahmedorns her­beizuführen, der vom Fußende her in die Flanschenspule ein­geführt wird, um diese beim Spulvorgang anzutreiben.The special configuration of the edge region 16 in the various embodiments of the flange according to the invention Serve coil is used here to bring about a tight guide on the upper end of a mandrel, not shown, which is inserted from the foot end into the flange coil to drive it during the winding process.

Der Aufnahmedorn wird üblicherweise auch an dem am weite­sten innen liegenden Ring 5 des Flansches 3 aufgenommen und geführt. Folglich liegt an diesem Ring 5 die bleiche Pro­blematik vor wie im Randbereich 16 der Führungshülse 12:
ein Spiel zwischen dem Aufnahmedorn einerseits und dem Ring beziehungsweise Randbereich 16 ist zu vermeiden, um opti­male Rundlaufeigenschaften auch bei hohen Drehzahlen sicherzustellen. Aufgrund der gleichen Problematik an den beiden bezeichneten Elementen sieht die Erfindung vor, die zur Lösung dieses Problems vorstehend in Verbindung mit dem Randbereich 16 beschriebenen Merkmale auch mit dem Ring 5 zu kombinieren.The mandrel is usually also received and guided on the innermost ring 5 of the flange 3. Consequently, this ring 5 has the pale problem as in the edge region 16 of the guide sleeve 12:
a play between the arbor on the one hand and the ring or edge area 16 is to be avoided in order to ensure optimum concentricity even at high speeds. Because of the same problem with the two designated elements, the invention provides that the features described above in connection with the edge area 16 also be combined with the ring 5 to solve this problem.
