Description

Die Erfindung betrifft eine Spindel für das Spinnen bzw. Zwirnen von Fäden auf Ringspinn-und bzw. oder Ringzwirnmaschinen mit reduziertem Fadenballon mit einem auf dem Spindelschaft sitzenden Spindelkopf mit den Faden bei seiner Drehung mitnehmenden und von diesem zu übergleitenden Fadenmitnehmern, welche über den von dem über den Spindelkopf laufenden Faden umschriebenen Rotationskörper hinausragen, und gegebenenfalls mit einem unter diesem befindlichen, sich nach unten verjüngenden Kegelkörper.The invention relates to a spindle for the spinning or twisting of threads on ring spinning and / or ring twisting machines with a reduced thread balloon with a spindle head seated on the spindle shaft with the thread taking along the thread during its rotation and to be slid over by it, which over the thread carrier Project a rotating body circumscribing the thread running over the spindle head, and if necessary with a tapered body located below it and tapering downwards.

Nachdem man gefunden hatte, daß es möglich ist, auf Ringspinn- bzw. Ringzwirnmaschinen « ballonlos bzw. richtiger ausgedrückt, mit reduziertem Fadenballon zu spinnen bzw. zu zwirnen, hat es an den verschiedensten Vorschlägen nicht gefehlt, diese Methode zu verbessern, weil sie beträchtliche Vorteile bietet.After it had been found that it was possible to spin or twist with a reduced thread balloon on ring spinning or ring twisting machines, there was no lack of various proposals to improve this method because it was considerable Offers advantages.

Das Hauptproblem beim Spinnen bzw. Zwirnen steht in engem Zusammenhang mit der Fadenspannung sowie mit Fadenspannungsschwankungen bzw. dem Ort, wo diese Fadenspannungen auftreten. Durch sie sind der Steigerung der Leistungsfähigkeit der gebräuchlichen Ringspinn- und -zwirnmaschinen Grenzen gesetzt, deren Erhöhung in jüngerer Zeit praktisch kaum noch gelungen ist, zumindest nicht in einem so bedeutenden Umfang, um mit den in Betracht kommenden Maschinen noch wirtschaftlicher arbeiten zu können.The main problem with spinning or twisting is closely related to the thread tension as well as with thread tension fluctuations or the place where these thread tensions occur. They set limits to the performance of the conventional ring spinning and twisting machines, the increase of which has hardly been successful in recent times, at least not to such an extent that the machines in question can work even more economically.

Mit diesen Problemen steht auch die Frage der Qualität des erhaltenen Erzeugnisses im engen Zusammenhang.The issue of the quality of the product obtained is closely related to these problems.

Es wurden bereits Spindeln mit besonders geformten Spindelköpfen bzw. auf den Spindeln aufsetzbaren Fadenführern empfohlen, durch die die Verhältnisse beim Spinnen und Zwirnen ohne oder mit reduziertem Fadenballon verbessert werden sollten, insbesondere hinsichtlich der Fadenspannung zwischen dem Lieferzylinder und dem Kopf.Spindles with specially shaped spindle heads or thread guides that can be placed on the spindles have already been recommended, by means of which the conditions during spinning and twisting without or with a reduced thread balloon should be improved, in particular with regard to the thread tension between the delivery cylinder and the head.

So sind bereits Spindeln mit Spindelköpfen für Ringspinn- und -zwirnmaschinen bekanntgeworden, bei welchen der Faden mittels an diesen angeordneten Gruppen von Mitnehmern verschiedenster Art schraubenlinienförmig über den Spindelkopf geführt wird. Die Mitnehmer bestehen z.B. aus prismatischen bzw. kegelförmigen, pyramidenähnlichen oder dgl. Vorsprüngen, die in unterschiedlichster Weise am Spindelkopf angeordnet sind. Dabei ist der Spindelkopf zumeist so ausgebildet, daß der von der Fadenführeröse kommende Faden möglichst ungestört und tangential auf entsprechend geformte Flächen des Spindelkopfes aufläuft, welche so abgerundet wie möglich ausgebildet sind, damit der Fadenlauf möglichst wenig gestört werden sollte. Da diese bekannten Vorsprünge am Spindelkopf die Aufgabe haben, den Faden mitzunehmen, sind sie dieser Aufgabe entsprechend ausgebildet und werden auch als Mitnehmer bezeichnet, denn sie sollen den Faden daran hindern, vom Spindelkopf fortzufliegen und einen Ballon zu bilden.Thus, spindles with spindle heads for ring spinning and twisting machines have already become known, in which the thread is guided in a helical manner over the spindle head by means of groups of carriers of various types arranged on these. The drivers consist e.g. made of prismatic or conical, pyramid-like or the like projections which are arranged in various ways on the spindle head. The spindle head is usually designed so that the thread coming from the thread guide eyelet runs as undisturbed and tangentially on appropriately shaped surfaces of the spindle head, which are as rounded as possible so that the thread run should be disturbed as little as possible. Since these known projections on the spindle head have the task of taking the thread with them, they are designed for this task and are also referred to as carriers, because they are intended to prevent the thread from flying away from the spindle head and forming a balloon.

Weiterhin wurde bereits vorgeschlagen, einen Spindelkopf zu verwenden, welcher aus einem im wesentlichen zylindrischen Körper besteht, über den der vom Fadenführer kommende Faden geführt wird und der als wesentliches Merkmal nutartige Einschnitte im Außenmantel aufweist (DE-PS 11 16 584 und DE-PS 1286438). Die in dem zylindrischen Körper des Spindelkopfes angeordneten nutartigen Einschnitte erstrecken sich nach oben bis zur Stirnfläche des Kopfes und endigen unten in der zylindrischen Mantelfläche, unterhalb welcher sich eine nach unten verjüngende Kegelmantelfläche befindet.Furthermore, it has already been proposed to use a spindle head which consists of an essentially cylindrical body, over which the thread coming from the thread guide is guided and which, as an essential feature, has groove-like incisions in the outer jacket (DE-PS 11 16 584 and DE-PS 1286438 ). The groove-like incisions arranged in the cylindrical body of the spindle head extend up to the end face of the head and end at the bottom in the cylindrical lateral surface, below which there is a conical lateral surface tapering downwards.

Es hat sich nun aber, nachdem die vorgenannten Spindelköpfe, vor allem diejenigen nach der DE-PS 11 16584 und der DE-PS 1286438. in sehr großen Stückzahlen und seit vielen Jahren benutzt werden, herausgestellt, daß diese trotz aller in sie gesetzten und im wesentlichen auch erfüllten Erwartungen noch Wünsche übriglassen, insbesondere hinsichtlich der Qualität der erhaltenen Fäden.It has now turned out, however, after the aforementioned spindle heads, especially those according to DE-PS 11 16584 and DE-PS 1286438. have been used in very large numbers and for many years, that these are used in spite of all and in leave much to be desired, especially with regard to the quality of the threads received.

Der Erfindung liegt die Aufgabe zugrunde, die Spindelköpfe der in Betracht kommenden vorbekannten Art noch weiter zu verbessern, um die aufgezeigten Nachteile zu vermeiden und einen möglichst störungsfreien Spin- bzw. Zwirnbetrieb zu gewährleisten, der einwandfreie, qualitativ hochwertige und völlig gleichmäßige Erzeugnisse liefert.The invention has for its object to further improve the spindle heads of the known type in question in order to avoid the disadvantages shown and to ensure as trouble-free a spin or twisting operation that delivers flawless, high quality and completely uniform products.

Es ist bekannt, daß beim Spinnen mit Selfaktoren der erhaltene Faden eine außerordentlich gute Gleichmäßigkeit aufweist, was darauf zurückzuführen ist, daß der Faden beim Ausfahren des Wagens infolge der sich drehenden Spindel und des dabei über den Spindel- bzw. Hülsenkopf springenden bzw. diesen überrollenden Fadens in transversale Schwingungen versetzt wird, wodurch eine bessere Orientierung und Ordnung der Fasern im Faden bereits von Beginn seiner Drehung an erreicht wird, die eine Qualitätsverbesserung des Fadens zur Folge hat.It is known that when spinning with self-actuators, the thread obtained has an extraordinarily good uniformity, which is due to the fact that the thread when the carriage extends as a result of the rotating spindle and thereby jumping or rolling over the spindle or sleeve head The thread is set in transverse vibrations, whereby a better orientation and order of the fibers in the thread is achieved right from the start of its rotation, which results in an improvement in the quality of the thread.

Im Rahmen dieser Erkenntnisse liegt die spezielle Aufgabe des Gegenstandes der Erfindung darin, insbesondere beim Ringspinnen zumindest ähnliche Verhältnisse wie beim Selfaktorspinnen zu schaffen.Within the framework of these findings, the special object of the subject matter of the invention is to create at least similar conditions to those for self-actuator spinning, especially in ring spinning.

Nach umfangreichen Experimenten zur Lösung der vorgenannten Aufgabe wurde überraschenderweise gefunden, daß sich gegenüber den vorbekannten Spindelköpfen beachtliche Verbesserungen erzielen lassen, wenn man in etwa ausgehend von einem Spindelkopf nach der DE-PS 11 16584 bzw. der DE-PS 1286438 diese in der Weise ausbildet, daß die Fadenmitnehmer aus einem am oberen Ende mit einer Abrundung versehenen, im wesentlichen vertikalen zylindrischen Zapfen bestehen, welcher über einen radialen Steg mit einem zentralen zylindrischen Körper verbunden ist, daß die Fadenmitnehmer den zentralen Körper überragen und daß die Oberkante der radialen Verbindungsstege auf der Verbindungslinie von der oberen Stirnfläche des zentralen Körpers zum höchsten Punkt der Fadenmitnehmer liegt.After extensive experiments to solve the aforementioned problem, it was surprisingly found that, compared to the known spindle heads, considerable improvements can be achieved if they are roughly formed from a spindle head according to DE-PS 11 16584 or DE-PS 1286438 that the thread drivers consist of a rounded, essentially vertical cylindrical pin at the upper end, which has a central radial cylindrical web Body is connected that the thread drivers project beyond the central body and that the upper edge of the radial connecting webs lies on the connecting line from the upper end face of the central body to the highest point of the thread drivers.

Bei Versuchen über einen ausreichend bemessenen Zeitraum zwecks Sicherung der erhaltenen Ergebnisse konnte festgestellt werden, daß beim Spinnen bzw. Zwirnen mit erfindungsgemäß ausgebildeten Spindelköpfen bestückten Spindeln der Faden leicht vibrierend läuft, während die Fadenspannung unverändert im günstigsten Bereich liegt, wodurch eine bessere Faserordnung und -dichte im kritischen Bereich erzielt wird und ein Faden erhalten werden kann, der wesentlich gleichmäßiger als bisher ist. Auch konnte festgestellt werden, daß der Drall des Fadens gleichmäßiger und besser geworden ist.In tests over a sufficiently long period of time to ensure the results obtained, it was found that when spinning or twisting with spindles designed according to the invention, the spindles run slightly vibrating, while the thread tension remains in the most favorable range, resulting in a better fiber order and density is achieved in the critical area and a thread can be obtained which is much more uniform than before. It was also found that the twist of the thread has become more even and better.

Versuche haben nun aber gezeigt, daß sich hinsichtlich bestimmter Fäden, insbesondere solcher, die sich schwieriger verspinnen bzw. zwirnen lassen, der zuvor beschriebene Spindelkopf noch verbessern läßt, um einen einwandfreien und störungsarmen Betrieb zu gewährleisten.Experiments have now shown, however, that with regard to certain threads, in particular those which are more difficult to spin or twist, the spindle head described above can still be improved in order to ensure flawless and trouble-free operation.

In weiterer Ausbildung des Gegenstands der Erfindung wird vorgeschlagen, die Spindelköpfe für die in Betracht kommenden Spindeln in der Weise auszubilden, daß die Oberkante der radialen Stege vom Zentrum der oberen Stirnfläche des zentralen zylindrischen Körpers ausgehend nach außen hin zunächst bis zu einem höchsten Punkt ansteigt und dann von diesem aus nach außen hin zum oberen Ende der zylindrischen Zapfen abfällt, wobei der höchste Punkt der Oberkante der raidalen Stege zwischen dem zentralen Körper und den zylindrischen Zapfen liegt.In a further development of the object of the invention it is proposed to design the spindle heads for the spindles in question in such a way that the upper edge of the radial webs initially rises outwards from the center of the upper end face of the central cylindrical body to a highest point and then descends from this outwards to the upper end of the cylindrical pegs, the highest point of the upper edge of the raidal webs being between the central body and the cylindrical pegs.

In den Figuren 1 bis 4 der Zeichnungen ist der gemäß der Erfindung verbesserte Spindelkopf anhand zweier bevorzugter Ausfüh.rungsbeispiele dargestellt, welche nachstehend im einzelnen näher beschrieben sind. Es zeigen :

  • Figur 1 einen Axialschnitt durch den oberen Teil einer Spindel mit erfindungsgemäß ausgebildetem Spindelkopf, teilweise im Schnitt,

  • Figure 4 is a plan view of the spindle head according to Figure 3.

Wie die Figuren 1 und 2 erkennen lassen, ist auf das obere Ende 11 des Spindeischafts12 der Spindelkopf 13 aufgesetzt, der aus einem unteren, kegelstumpfförmigen Teil 14 und einem oberen Kopfteii15 besteht, an welchem die Fadenmitnehmer 16 angeordnet sind. Die Fadenmitnehmer 16 bestehen aus im wesentlichen vertikalen, zylindrischen Zapfen, die sich von der oberen, größeren Stirnfläche 17 des unteren Kopfteils 14 nach oben erstrecken und ein oberes, ebenes, kuppelförmiges oder kegelförmiges Kopfende 18 aufweisen. Die Fadenmitnehmer 16 sind mittels radialer Stege 19 mit einem zentralen, zylindrischen Körper 20 verbunden, dessen oberen horizontale Stirnfläche 21 axial tiefer liegt als die höchsten Punkte 22 der Kopfenden 18 der Fadenmitnehmer 16. Die Oberkante 23 der Stege 19 liegt auf der Verbindungslinie zwischen der Stirnfläche 21 des zentralen Körpers und dem höchsten Punkt 22 der Kopfenden 18 der Fadenmitnehmer 16 und steigt von innen nach außen unter einem Winkel a gegenüber einer Horizontalebene an. Im Spindelkopf 13 befindet sich eine axiale Bohrung 24 für die Aufnahme des Bolzens 25, mit welchen der Spindelkopf 13 auf dem Spindelschaft 12 befestigt ist.As can be seen in FIGS. 1 and 2, the spindle head 13, which consists of a lower, frustoconical part 14 and an upper head part 15, on which the thread carriers 16 are arranged, is placed on the upper end 11 of the spindle shaft 12. The thread carriers 16 consist of essentially vertical, cylindrical pins which extend upwards from the upper, larger end face 17 of the lower head part 14 and have an upper, flat, dome-shaped or conical head end 18. The thread carriers 16 are connected by means of radial webs 19 to a central, cylindrical body 20, the upper horizontal end face 21 of which lies axially lower than the highest points 22 of the head ends 18 of the thread carriers 16. The upper edge 23 of the webs 19 lies on the connecting line between the end face 21 of the central body and the highest point 22 of the head ends 18 of the thread drivers 16 and rises from the inside to the outside at an angle a with respect to a horizontal plane. In the spindle head 13 there is an axial bore 24 for receiving the bolt 25, with which the spindle head 13 is fastened on the spindle shaft 12.
