Abstract

In the shrink bobbin, especially for smooth filament yarn, having a rotationally symmetrical body which possesses a casing forming a supporting surface for the yarn and having supporting webs (5, 6) extending in the longitudinal direction between end rings (1, 2) and supported circumferentially against one another via deformable shrinkage elements (8), its deformation is dependent on the residual shrinkage of the material to be processed and builds up flexibly to maximum shrinkage. The yarn package is thus not deformed, and a direct processing of the wound yarn is possible. The supporting webs (5, 6) are connected directly to the end rings (1, 2). Arranged between the supporting webs (5, 6) are stay webs (7) which extend essentially in the circumferential direction and the ends of which are each supported on a supporting web (7) via respective deformable shrinkage elements (8). <IMAGE>

Description

Die Erfindung betrifft eine Schrumpfhülse, insbesondere für Filament-Glattgarn, mit einem rotationssymmetrischen Körper, der einen eine Tragfläche für das Garn bildenden Mantel mit in Längsrichtung zwischen Endringen verlaufenden, in Umfangsrichtung über verformbare Schrumpfelemente aneinander abgestützten Tragstegen aufweist.The invention relates to a shrink sleeve, in particular for smooth filament yarn, with a rotationally symmetrical body which has a jacket forming a supporting surface for the yarn with supporting webs supported against one another in the longitudinal direction between end rings and supported in the circumferential direction via deformable shrinking elements.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Schrumpfhülse der eingangs erwähnten Art so auszubilden, daß sich ihre Verformung nach dem Restschrumpf des zu bearbeitenden Materials, insbesondere eines Filament-Glattgarns, richtet und sich flexibel bis zum Maximalschrumpf ausbaut. Das Garnpaket soll dabei nicht deformiert werden, so daß eine Direktverarbeitung des aufgespulten Garns möglich ist.The object of the present invention is to design a shrink sleeve of the type mentioned at the outset in such a way that its deformation is based on the residual shrinkage of the material to be processed, in particular a smooth filament yarn, and is flexibly expanded to maximum shrinkage. The yarn package should not be deformed, so that a direct processing of the wound yarn is possible.

Diese Aufgabe wird bei einer Schrumpfhülse der eingangs erwähnten Art erfindungsgemäß dadurch gelöst, daß die Tragstege unmittelbar an die Endringe angeschlossen sind, daß zwischen den Tragstegen im wesentlichen in Umfangsrichtung verlaufende Stützstege angeordnet sind, deren Enden sich jeweils über verformbare Schrumpfelemente an einem Tragsteg abstützen.This object is achieved according to the invention in a shrink sleeve of the type mentioned at the outset in that the support webs are connected directly to the end rings, that support webs running essentially in the circumferential direction are arranged between the support webs, the ends of which are each supported on a support web via deformable shrink elements.

Die Verformung der Schrumpfhülse erfolgt dabei in Abhängigkeit von dem in dem zu bearbeitenden Material noch gegebenen Restschrumpf. Der Garnwickel bleibt in seiner Form erhalten, so daß das Garn nach dem Schrumpfen ohne weiteres von der Schrumpfhülse direkt abgespult und weiter verarbeitet werden kann.The shrink sleeve is deformed as a function of the residual shrinkage still present in the material to be processed. The yarn package is retained in its shape, so that after shrinking the yarn can be easily unwound from the shrink sleeve and processed further.

Die erfindungsgemäße Schrumpfhülse kann ferner so ausgebildet sein, daß die Stützstege jeweils einen in einer Radialebene liegenden Kranz bilden.The shrink sleeve according to the invention can also be designed so that the support webs each form a ring lying in a radial plane.

Die erfindungsgemäße Schrumpfhülse kann ferner so ausgebildet sein, daß die Stützstege im Bereich ihrer Längsmitte mit mindestens einem Tragsteg starr verbunden sind. Dadurch wird der Aufbau der Schrumpfhülse besonders stabil, ohne die radiale Nachgiebigkeit zu stören.The shrink sleeve according to the invention can also be designed such that the support webs are rigidly connected to at least one support web in the region of their longitudinal center. This makes the construction of the shrink sleeve particularly stable without interfering with the radial flexibility.

Die erfindungsgemäße Schrumpfhülse kann ferner so ausgebildet sein, daß die in Umfangsrichtung aufeinanderfolgenden Tragstege alternierend mit Stützstegen ausschließlich starr oder ausschließlich über Schrumpfelemente verbunden sind.The shrink sleeve according to the invention can also be designed in such a way that the support webs which follow one another in the circumferential direction are alternately connected with support webs exclusively rigidly or exclusively via shrink elements.

Die erfindungsgemäße Schrumpfhülse kann ferner so ausgebildet sein, daß die Schrumpfelemente bügelförmig ausgebildet sind, sich mit ihren Schenkein an einem Tragsteg abstützen und im mittleren Bereich eines Quersteges mit einem Stützsteg verbunden sind. Die Schrumpfelemente sind dabei vorzugsweise U-förmig, V-förmig oder bogenförmig ausgebildet.The shrink sleeve according to the invention can also be designed so that the shrink elements are bow-shaped, are supported with their legs on a supporting web and are connected to a supporting web in the central region of a transverse web. The shrinking elements are preferably U-shaped, V-shaped or curved.

Die erfindungsgemäße Vorrichtung kann ferner so ausgebildet sein, daß die Schrumpfelemente mit Schrumpfbegrenzungselementen versehen sind, die beim radialen Zusammendrücken mit dem zugehörigen Tragsteg zusammenarbeiten. Somit kann der Umfang, auf den die Schrumpfhülse maximal zusammengedrückt werden kann, genau definiert werden.The device according to the invention can also be designed in such a way that the shrink elements are provided with shrinkage limiting elements which cooperate with the associated supporting web during radial compression. The extent to which the shrink sleeve can be maximally compressed can thus be precisely defined.

Die erfindungsgemäße Schrumpfhülse kann ferner so ausgebildet sein, daß die Tragstege an ihren beiden sich an die Endringe anschließenden Enden reduzierten Querschnitt haben. Hierdurch wird die Verformung am Übergang zwischen den Endringen einerseits und den Tragstegen andererseits erleichtert und einem bestimmten Bereich der Tragstege zugeordnet.The shrink sleeve according to the invention can also be designed so that the supporting webs have a reduced cross section at their two ends adjoining the end rings. As a result, the deformation at the transition between the end rings on the one hand and the supporting webs on the other hand is facilitated and assigned to a specific area of the supporting webs.

Die erfindungsgemäße Schrumpfhülse kann ferner so ausgebildet sein, daß die Außenflächen der Tragstege an ihren beiden sich an die Endringe anschließenden Enden in Richtung auf die Endringe nach radial innen abfallen. Durch das radiale Zusammendrücken wird die somit anfänglich in der Tragfläche nahe den Endringen vorhandene Neigung reduziert und abgebaut. Dadurch wird ein Abrutschen in den Randzonen des Garnwickels verhindert.The shrink sleeve according to the invention can also be designed such that the outer surfaces of the supporting webs at their two ends adjoining the end rings fall radially inward in the direction of the end rings. The radial compression reduces the inclination initially present in the wing near the end rings and dismantled. This prevents slipping in the edge zones of the yarn package.

Die erfindungsgemäße Schrumpfhülse kann ferner so ausgebildet sein, daß zumindest auf einem Endring Raum zur Aufnahme einer Fadenreserve vorgesehen ist.The shrink sleeve according to the invention can also be designed such that space is provided at least on an end ring for receiving a thread reserve.

schließlich kann die erfindungsgemaße Schrumpfhülse so ausgebildet sein, daß der an einem Ende eines ersten Wickelträgers befindliche Endring in den am anderen Ende eines zweiten Wickelträgers befindlichen Endring zumindest zum Teil einsteckbar ist. Auf diese Weise wird der erforderliche Stapel- und Transportraum wesentlich reduziert.Finally, the shrink sleeve according to the invention can be designed such that the end ring located at one end of a first winding support can be at least partially inserted into the end ring located at the other end of a second winding support. In this way, the required stacking and transport space is significantly reduced.

Die in den Fig. 1 - 4 dargestellte Ausführungsform der erfindungsgemäßen Schrumpfhülse hat einen unteren Endring 1 und einen oberen Endring 2. Dabei ist der untere Endring 1 in den oberen Endring 2 eines axial benachbarten Wickelträgers einsetzbar. Der obere Endring 2 hat eine Mantelfläche 3 und ist mit einer Fadenreservenut 4 versehen.The embodiment of the shrink sleeve according to the invention shown in FIGS. 1-4 has a lower end ring 1 and an upper end ring 2. The lower end ring 1 can be inserted into the upper end ring 2 of an axially adjacent winding carrier. The upper end ring 2 has a lateral surface 3 and is provided with a thread reserve groove 4.

Es sind parallel zur Achse des Wickelträgers verlaufende Tragstege 5, 6 vorgesehen, die sich an ihren Enden jeweils an den unteren Endring 1 bzw. den oberen Endring 2 anschließen.There are supporting webs 5, 6 running parallel to the axis of the winding support, each of which connects at its ends to the lower end ring 1 or the upper end ring 2.

In Umfangsrichtung wechseln jeweils Tragstege 5 und Tragstege 6 ab, wobei die Tragstege 5 starr mit Stützstegen 7 verbunden sind, die in Umfangsrichtung verlaufen und dabei beiderseits um das gleiche Maß über einen Tragsteg 5 hinausreichen. Die von dem jeweiligen Tragsteg 5 abgewandten Enden der Stützstege 7 schließen mittig an nachgiebige, bogenförmig ausgebildete Schrumpfelemente 8, die an ihren beiden Enden 9 an einen Tragsteg 6 angeschlossen sind. Die Tragstege 6 sind mit Ausnahme der Anbindung der Schrumpfelemente 8 ebenso ausgebildet wie die Tragstege 5.In the circumferential direction, support webs 5 and support webs 6 alternate, the support webs 5 being rigidly connected to support webs 7 which run in the circumferential direction and extend on both sides by the same amount beyond a support web 5. The ends of the support webs 7 facing away from the respective support web 5 are centrally connected to flexible, arched shrink elements 8 which are connected at their two ends 9 to a support web 6. With the exception of the connection of the shrinking elements 8, the supporting webs 6 are designed in the same way as the supporting webs 5.

Die Schrumpfelemente 8 sind mit Schrumpfbegrenzungselementen 10 versehen, die in der Ausgangsposition (Fig. 1) mit Abstand von dem zugehörigen Tragsteg 6 liegen. Der Abstand zwischen den Schrumpfbegrenzungselementen 10 und dem zugehörigen Tragsteg 6 definiert das Maß, um welches der Umfang der Schrumpfhülse maximal reduziert werden kann.The shrinking elements 8 are provided with shrinkage limiting elements 10, which in the starting position (FIG. 1) are at a distance from the associated supporting web 6. The distance between the shrinkage limiting elements 10 and the associated one Support bar 6 defines the extent by which the circumference of the shrink sleeve can be reduced to a maximum.

Im Ausführungsbeispiel bilden die Stützstege 7 in Umfangsrichtung unter Zwischenschaltung der Schrumpfelemente 8 und der Tragstege 6 einen in einer Radialebene liegenden Kranz. Derartige Kränze sind äquidistant über die Höhe der Schrumpfhülse verteilt.In the exemplary embodiment, the support webs 7 form a ring lying in a radial plane in the circumferential direction with the interposition of the shrinking elements 8 and the support webs 6. Wreaths of this type are distributed equidistantly over the height of the shrink sleeve.

Die Außenflächen der Tragstege 5, 6 definieren eine Trag- oder Wickelfläche für das aufzunehmende Garn. Diese Tragfläche fällt in der Ausgangsposition der Schrumpfhülse (Fig. 1) nahe den Endringen 1, 2 nach radial innen ab, bildet also eine zum jeweiligen Ende hin geneigte Konusfläche 11. Die Kornusflächen 11 sind im Bereich des unteren Endrings 1 durch einen Ringbund 12 und im Bereich des oberen Endrings durch eine Schulter 13 begrenzt.The outer surfaces of the supporting webs 5, 6 define a supporting or winding surface for the yarn to be picked up. This wing falls in the starting position of the shrink sleeve (Fig. 1) near the end rings 1, 2 radially inward, thus forming a conical surface 11 inclined towards the respective end. The corneal surfaces 11 are in the area of the lower end ring 1 by an annular collar 12 and limited by a shoulder 13 in the area of the upper end ring.

Wenn nun auf eine Schrumpfhülse gemäß Fig. 1 ein Garn, z. B. ein Filament-Glattgarn, mit Restschrumpf aufgespult wird, dann führt die Schrumpfung des Garns zur Verformung der Schrumpfhülse aus der in Fig. 1 dargestellten Ausgangsposition in die in Fig. 3 dargestellte geschrumpfte Position. In dieser Position stellt sich die Trag- oder Wickelfläche im wesentlichen zylindrisch dar. Die bogenförmigen Schrumpfelemente sind in ihrem mittleren Bereich eingedrückt, und die Schrumpfbegrenzungselemente 10liegen an den Tragstegen 6 an.If now on a shrink sleeve according to FIG. 1, a yarn, for. B. a filament smooth yarn is wound with residual shrinkage, then the shrinkage of the yarn leads to the deformation of the shrink sleeve from the starting position shown in Fig. 1 in the shrunk position shown in Fig. 3. In this position, the supporting or winding surface is essentially cylindrical. The arcuate shrinking elements are pressed in in their central area, and the shrinkage limiting elements 10 bear against the supporting webs 6.

Die radiale Wandstärke der Tragstege 5 und 6 ist im Bereich der Kornusflächen 11 in Richtung auf den jeweiligen Endring zunehmend reduziert, um die Verformung der Tragstege 5, 6 in diesem Bereich zu erleichtern. Dadurch wird ein Abrutschen in den Randzonen des Garnwickels verhindert und eine anschließende Direktverarbeitung ermöglicht.The radial wall thickness of the supporting webs 5 and 6 is increasingly reduced in the area of the corneal surfaces 11 in the direction of the respective end ring in order to facilitate the deformation of the supporting webs 5, 6 in this area. This prevents slipping in the edge zones of the yarn package and enables subsequent direct processing.

Die in den Fig. 5 - 8 dargestellte weitere Ausführungsform der erfindungsgemäßen Schrumpfhülse weicht lediglich durch die Ausgestaltung der Schrumpfelemente 8 von der zuvor beschriebenen Ausführungsform ab. Nach Fig.5 - 7 sind diese Schrumpfelemente 8 U-förmig ausgebildet, haben also jeweils zwei parallel zueinander verlaufende Schenkel 15 und einen in der Ausgangsposition (Fig. 5) parallel zum Tragsteg 6 verlaufenden Quersteg 14. An diesen Quersteg 14 ist mittig jeweils ein Stützsteg 7 angelenkt.The further embodiment of the shrink sleeve according to the invention shown in FIGS. 5-8 differs from the one described above only by the configuration of the shrink elements 8 Embodiment from. According to FIGS. 5-7, these shrinking elements 8 are U-shaped, that is to say they each have two legs 15 running parallel to one another and a transverse web 14 running parallel to the supporting web 6 in the starting position (FIG. 5) Support bridge 7 articulated.

In den Fig. 9 und 10 ist eine weitere Ausführungsform der erfindungsgemäßen Schrumpfhülse dargestellt, welche ebenfalls allein die Ausbildung der Schrumpfelemente 8 betrifft. Hier sind diese Schrumpfelemente 8 V-förmig ausgebildet, haben also in Richtung auf den angeschlossenen Stützsteg 7 aufeinanderzu geneigte Schenkel 16.9 and 10 show a further embodiment of the shrink sleeve according to the invention, which likewise only relates to the configuration of the shrink elements 8. Here, these shrinking elements 8 are V-shaped, that is to say they have legs 16 which are inclined towards one another in the direction of the connected support web.

In den dargestellten Ausführungsbeispielen sind die Schrumpfelemente 8 jeweils an einen Stützsteg 6 angeschlossen, während die Stützstege 5 frei von solchen Schrumpfelementen sind. Es ist aber auch möglich, z. B. alternierend an ein und demselben Tragsteg 5, 6 in axialer Richtung Schrumpfelemente 8 und starre Verbindungen mit Stützstegen 7 aufeinanderfolgen zu lassen.In the illustrated exemplary embodiments, the shrinking elements 8 are each connected to a supporting web 6, while the supporting webs 5 are free from such shrinking elements. But it is also possible, for. B. alternately on one and the same support web 5, 6 in the axial direction shrink elements 8 and rigid connections with support webs 7 can follow one another.

Die Schrumpfhülsen nach den beschriebenen Ausführungsformen sind aus thermoplastischem Kunststoff in Spritzverfahren herstellbar.The shrink sleeves according to the described embodiments can be produced from injection molded thermoplastic.
