Abstract

The cross-winding mechanism is for use with conical spools, where the spool is driven by a friction roller and the thread laid by a guide. The point (2) where the spool (1) bears against the driving roller (3) is moved with the thread guide, and the roller has a flexible outer wall rotating about eccentric axes so that it assumes an oblong spiral form. The eccentric axes are moved so as to synchronise the contact point with the guide. The roller wall can be of elastomer or textile material, or of one or more concentric spirals of metal.

Description

Kreuzwickel-Aufspul-Einrichtung Cross winding device

für Konushülsen Die Erfindung setritft eine Aufspuleinrichtung für konische, durch Friktion angetriebene Kreuzspulen. Die llerstellung von Konus-Kreuzspulen durch Friktionsantrieb bei einem Umspulvorgang ist bekannt, wobei die Garnzuführung entsprechend dem variablen Umfang des nit konstanter Drehgeschwindigkeit rotierenden Kegelstumpfes mit variabler Geschwindigkeit vor sich geht. Das fierstellen einer Konusspule wir aber problematisch, wenn, wie etwa bei Spinnmaschinen einer Lufttexturiermaschinen, eine Garnzuführung $Antrieb $Kurvenhahb Zur Lösung dieses Problems wurcle bereits vorgeschlagen, die konische Kreuzspule uurcn eine mit einem Fadenführer gekoppelt hin- und hergehende ballige AntrieDsrolle in Rotation zu versetzen ocjer den Antrieb ciurch ein endloses Band mit darauf erhaben angeordneter Kurvenbahn vorzunehmen oder aber getrennte Antriebs- und Unterstützungselemente für die Konusspule zu verwenden. Alle diese Anorclnungen konnten sich nicht durch setzen, entweder weil es zu Furchenbildungen in der Spule kam, oder dazu, dass die spule nur noch einseitig auf em unterstützenden Element auflag und der Antrieb gänzlich unterblieb, wenn das betreffende Unterstützungselement nicht in Kontakt mit dem anteilbenden Element war. for conical sleeves The invention meets a winding device for conical packages driven by friction. The production of cone packages by friction drive in a rewinding process is known, the yarn feed rotating according to the variable scope of the constant rotation speed The truncated cone is going on at variable speeds. The fierstellen one However, conical bobbins are problematic if, as in the case of spinning machines of an air texturing machine, a twine feed $ drive $ camshaft. This problem has already been solved proposed that the conical package uurcn coupled with a thread guide reciprocating spherical drive roller to set in rotation or the drive ci by an endless belt with a raised curved track on it or to use separate drive and support elements for the cone coil. All of these anomalies could not prevail, either because furrows were formed came in the coil, or that the coil only supported on one side on em Element rested and the drive did not take place when the relevant support element was not in contact with the participating element.

Die erfindung hat die Aufgabe, die genauen Nachteile zu vermeiden und das Wickeln einer einwandfreien konischen Kreuzspule bei gleichförmiger Garnzuführung zu ermöglichen.The task of the invention is to avoid the precise disadvantages and winding a flawless conical cheese with uniform yarn feed to enable.

Die an sich richtige Aufgabenstellung der bekannten Lösungsversuche, mit dem FadenfUhrer den Friktionspunkt eines antreibenden Elements am jeweiligen Nantellinienpunkt der konischen Spule mitzubewegen, wird efindungsgemäss dadurch gelöst, dass der Antriebszylinder mit einer flexiblen Aussenwand ausgebildet ist, die um derart exzentrisch angeordnete Achsen rotiert, dass der Antriebszylinder schraubenartig verformt erscheint. Die hier gemeinte Schraubenform hat eine sehr viel grossere Steigung, als "Gewinde"-Tiefe -Tiefe und weniger als 1 Ganghöhe Lange. Ein solches Gebilde Uberall annähernd kreisförmigen Querschnitts kat hat zu jeder beliebigen Tangente, also auch zu einer die möglichen Auflagepunkte verbindenden Nantellinie des aufliegenden Kegelstumpfes, nur einen einzigen Berührungspunkt. Dieser Punkt kann offenbar durch Rotations der Schraube um ihre achse in achsialer Richtung bewegt werden. Es ist Teil der erfinderischen Idee, die exzentrischen Teilachsen derart um eine gemeinsame Achse zu drehen, dass sich <jer Auflagepunkt gerade mit dem Fadenführer mitbewegt.The per se correct task of the known solution attempts, Use the thread guide to determine the friction point of a driving element on the respective Moving the circumferential line point of the conical coil is thereby achieved according to the invention solved that the drive cylinder is designed with a flexible outer wall, which rotates about such eccentrically arranged axes that the drive cylinder appears helically deformed. The screw shape meant here has a very Much larger pitch than "thread" -depth -depth and less than 1 pitch length. One such Formations almost circular cross-section everywhere kat has the possible support points for any tangent, including one connecting nantellar line of the truncated cone on top, only a single point of contact. This point can evidently be made axially by rotating the screw about its axis Direction to be moved. It is part of the inventive idea, the eccentric partial axes to rotate around a common axis in such a way that <each point of support is straight moved with the thread guide.

Die Oberfläche von Antriebsrollen der bekannten iurt wie auch der erfinderischen Art ist mechanischen Beanspruchungen ausgesetzt. Die flexible Aussenwand des ertinderischen Antriebselements kann erfindungsgemãss aus einem abtriebfeste Elastomer oder einem Gewebe in Schlauchform hergestellt werden oder/ und aus einem spiralförmig gewickelten Gebilde z.B. aus metall stehen, woDei es besonders vorteilhaft sein kann, zwei gegenläufige Spiralen konzentrisch zueinander zu verwenden.The surface of drive rollers of the well-known iurt as well as the inventive type is exposed to mechanical stresses. The flexible outer wall According to the invention, the electric drive element can consist of a fixed output Elastomer or a fabric can be produced in tubular form and / or from a Spirally wound structures e.g. made of metal, where it is particularly advantageous can be to use two counter-rotating spirals concentric to each other.

Die Erfindung wird anhand der zeichnerischen Darstellung in Fig. 1 näher beschrieben. 1 bedeutet die Konusspule, 2 zeigt deren momentanen Auflagepunkt auf der schraubenförmigen Antriebsrolle 3, deren Rotationsantrieb von der Seite 4 erfolgt, 5 bedeutet den Fadenführer, dessen grosshubige Hin- und Herbewegung durch den spiralig geschlitzten Zylinder 6 in den für die Änderung der Schraubenposition gengenden relativ kleinen liub umgewandelt wird und mittels Zahnstange 7 auf die Schraubenachse übertragen wird. Die hin- und hergehende Verdrehung der Schraubenachse kann ebensogut durch eine Pleuelstange erzielt werden.The invention is illustrated by the drawing in FIG. 1 described in more detail. 1 means the cone coil, 2 shows its current point of support on the helical drive roller 3, whose rotary drive from the side 4 takes place, 5 means the thread guide whose large-stroke back and forth movement occurs the spirally slotted cylinder 6 in the for changing the screw position Sufficient relatively small liub is converted and by means of rack 7 on the Screw axis is transmitted. The back and forth rotation of the screw axis can be achieved just as well by a connecting rod.
