Definitions
- the present invention relates to a rotor for ring spinning machines according to the preamble of claim 1.
- a rotor for ring spinning machines From DE-U-78 14 259 various designs of rotor for conical spinning rings are known.
- the runner claimed there has a thread guide part consisting of two symmetrical lying straight sections converging at an angle. With this design, the disadvantage of too narrow a passage for the yarn between the ring and the rotor is to be eliminated, as is described, for example, in DE-B-12 84 338.
- the thread guide part consisting of straight sections results in a substantially larger passage cross section between the ring and the runner than in the case of a semi-arch-shaped guide part.
- this geometry of the guide part with the small radius precisely defines the thread path. This leads to rapid wear of the rotor in the apex radius between the straight sections.
- the object of the present invention is to create a runner which has a sufficiently large thread passage and has good thread running properties without the mass and thus the centrifugal forces increasing compared to the known runners.
- Another task is to ensure a low-friction run for thick spots and piecing.
- the straight section of the guide part ensures a large through opening between the runner and the ring, and the subsequent quarter-curve piece brings the undefined guide surface necessary for the running of the yarn and therefore no local wear.
- the large radius of the quarter arch means that no individual fibers are pushed on and piecing cannot jam. This is particularly advantageous for very fine yarns with a small ring and runner.
- the runners 1 and 2 shown in FIGS. 1 and 2 and known from the prior art are shown in the functional position on a ring 3.
- the narrow passage for the yarn 5 between the runner 1 and the upper edge of the ring 3 can clearly be seen (FIG. 1).
- the yarn 5 always runs exactly in the apex 8 of the two straight sections 6, 7.
- the runners 9 in FIGS. 3 and 4 have a guide part which has a quarter curve 10 for the thread passage between the short leg 12 and the apex 8 and a straight to slightly curved section 14 between the apex 8 and the long leg 13.
- the radii of the rotor 9 advantageously have the following values:
- the runner 11 shown in FIG. 5 differs from the runner 9 by legs 12, 13 widening in a V-shape and other values for the radii, which are preferably assumed as follows: R 1 1,5 1.5 mm, R 2 0,8 0.8 mm and r ⁇ 1 mm.
- FIG. 6 shows a runner 15, measured in detail, as can be used for the Tex 20 number range.
- the mass of this rotor 15 corresponds to ISO standard No. 2266, series R20, No. 45 (ie 1,000 pieces weigh 45 grams).
- the two small radii r and R 2 1.2 mm for section 14 are clearly visible.
- the radius of the arc R 1 is significantly larger (1.6 mm).

Description
Die vorliegende Erfindung bezieht sich auf einen Läufer für Ringspinnmaschinen gemäss Oberbegriff des Patentanspruches 1. Aus dem DE-U-78 14 259 sind verschiedene Ausbildungen von Läufern für kegelförmige Spinnringe bekannt. Der dort beanspruchte Läufer weist einen aus zwei symmetrisch liegenden, in einem Winkel zusammenlaufenden geraden Teilstücken bestehenden Fadenführerteil auf. Mit dieser Ausbildung soll der Nachteil eines zu engen Durchganges für das Garn zwischen Ring und Läufer behoben werden, wie es beispielsweise in der DE-B-12 84 338 beschrieben wird.The present invention relates to a rotor for ring spinning machines according to the preamble of claim 1. From DE-U-78 14 259 various designs of rotor for conical spinning rings are known. The runner claimed there has a thread guide part consisting of two symmetrical lying straight sections converging at an angle. With this design, the disadvantage of too narrow a passage for the yarn between the ring and the rotor is to be eliminated, as is described, for example, in DE-B-12 84 338.
Tatsächlich ergibt sich bei dem aus geraden Teilstücken bestehenden Fadenführungsteil ein wesentlich grösserer Durchgangsquerschnitt zwischen Ring und Läufer als bei einem halbbogenförmigen Führungsteil. Allerdings wird durch diese Geometrie des Führungsteiles mit dem kleinen Radius der Fadenlauf genau definiert. Dies führt zu raschem Verschleiss des Läufers im Scheitelradius zwischen den geraden Teilstücken.In fact, the thread guide part consisting of straight sections results in a substantially larger passage cross section between the ring and the runner than in the case of a semi-arch-shaped guide part. However, this geometry of the guide part with the small radius precisely defines the thread path. This leads to rapid wear of the rotor in the apex radius between the straight sections.
Es kann auch nicht vermieden werden, dass sich im Radius Dickstellen und Ansetzer trotz grossem Durchgangsquerschnitt verklemmen und schlecht durchlaufen. Weiter neigt diese Läuferform dazu, Einzelfasern an der Garnoberfläche aufzuschieben, was zu haarigem Garn und zu Nissenbildung führen kann.It can also not be avoided that thick spots and attachments jam in the radius and run through poorly despite the large passage cross-section. Furthermore, this runner shape tends to push individual fibers onto the surface of the yarn, which can lead to hairy yarn and to the formation of nits.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, einen Läufer zu schaffen, welcher einen genügend grossen Fadendurchgang aufweist und gute Fadenlaufeigenschaften hat, ohne dass die Masse und damit die Fliehkräfte gegenüber den bekannten Läufern zunehmen.The object of the present invention is to create a runner which has a sufficiently large thread passage and has good thread running properties without the mass and thus the centrifugal forces increasing compared to the known runners.
Eine weitere Aufgabe besteht darin, für Dickstellen und Ansetzer einen reibungsarmen Durchlauf zu gewähren.Another task is to ensure a low-friction run for thick spots and piecing.
Erfindungsgemäss werden diese Aufgaben gemäss dem Kennzeichen des Patentanspruches 1 gelöst.According to the invention, these objects are achieved in accordance with the characterizing part of patent claim 1.
Weitere vorteilhafte Ausführungsformen ergeben sich aus den Ansprüchen 2 und 3.Further advantageous embodiments result from claims 2 and 3.
Ueberraschenderweise werden die Nachteile der bekannten Läufer durch die vorgeschlagene neuartige Ausbildung des Führungsteiles behoben, ohne dass die guten Laufeigenschaften der bekannten Läufer auf dem Ring in irgendeiner Weise beeinträchtigt werden.Surprisingly, the disadvantages of the known runners are eliminated by the proposed novel design of the guide part, without the good running properties of the known runners on the ring being impaired in any way.
Der gerade Abschnitt des Führungsteiles gewährleistet eine grosse Durchgangsöffnung zwischen Läufer und Ring und das anschliessende Viertelsbogenstück bringt die für den Lauf des Garnes notwendige undefinierte Führungsfläche und damit keinen örtlichen Verschleiss.The straight section of the guide part ensures a large through opening between the runner and the ring, and the subsequent quarter-curve piece brings the undefined guide surface necessary for the running of the yarn and therefore no local wear.
Des weiteren werden durch den grossen Radius des Viertelsbogens keine Einzelfasern aufgeschoben und Ansetzer können nicht verklemmen. Insbesondere bei sehr feinen Garnen mit kleinem Ring und Läufer wirkt sich dies besonders vorteilhaft aus.Furthermore, the large radius of the quarter arch means that no individual fibers are pushed on and piecing cannot jam. This is particularly advantageous for very fine yarns with a small ring and runner.
Die Erfindung wird nun im folgenden anhand von Ausführungsbeispielen näher erläutert.The invention will now be explained in more detail below with the aid of exemplary embodiments.
Es zeigen :
- Figuren 1 und 2 ein Querschnittprofil durch einen Spinnring mit herkömmlichem Läufer,
- Figur 3 ein Querschnittprofil durch einen Spinnring mit einem Läufer gemäss der Erfindung,
- Figur 4 einen Läufer nach Figur 3, vergrössert dargestellt,
Figur 5 einen Läufer nach Figur 4, jedoch mit v-förmiger Anordnung der Schenkel, speziell für feine Garnnummern mit entsprechend kleinem Ringprofil und Läufer,- Figur 6 einen Läufer mit konkreter Vermassung.
- 1 and 2 show a cross-sectional profile through a spinning ring with a conventional rotor,
- FIG. 3 shows a cross-sectional profile through a spinning ring with a rotor according to the invention,
- FIG. 4 shows a rotor according to FIG. 3, enlarged,
- 5 shows a runner according to FIG. 4, but with a v-shaped arrangement of the legs, especially for fine thread numbers with a correspondingly small ring profile and runner,
- Figure 6 shows a runner with concrete dimensions.
Die in den Figuren 1 und 2 gezeigten, aus dem Stand der Technik bekannten Läufer 1 und 2 sind in Funktionsstellung auf einem Ring 3.dargestellt. Beim Läufer 1 mit halbbogenförmigem Führungsteil 4 ist deutlich der enge Durchgang für das Garn 5 zwischen dem Läufer 1 und der Oberkante des Ringes 3 ersichtlich (Fig. 1). Die Ausbildung des Führungsteiles des Läufers 2 aus zwei symmetrischen, in einem Winkel vorgesehenen geraden Abschnitten 6, 7 (Fig. 2) bringen ganz offensichtlich eine wesentliche Querschnittvergrösserung für den Garndurchgang. Allerdings läuft das Garn 5 immer genau im Scheitel 8 der beiden geraden Abschnitte 6, 7.The runners 1 and 2 shown in FIGS. 1 and 2 and known from the prior art are shown in the functional position on a ring 3. In the case of the runner 1 with the semicircular guide part 4, the narrow passage for the
Die Läufer 9 in Figur 3 und 4 haben einen Führungsteil, welcher zwischen dem kurzen Schenkel 12 und dem Scheitel 8 einen Viertelsbogen 10 für den Fadendurchlauf und zwischen dem Scheitel 8 und dem langen Schenkel 13 einen geraden bis leicht gebogenen Abschnitt 14 aufweist.The
Für Garn 5 mit Dickstellen ergibt sich ein grosser Durchgangsquerschnitt und gleichzeitig auf dem anschliessenden Bogenstück 10 die erwünschte breite, nicht definierte freie Gleitfläche. Die Radien des Läufers 9 weisen vorteilhafterweise folgende Werte auf :
Der in Figur 5 dargestellte Läufer 11 unterscheidet sich vom Läufer 9 durch v-förmig sich erweiternde Schenkel 12, 13 sowie andere Werte für die Radien, welche vorzugsweise wie folgt angenommen werden : R1 ≥ 1,5 mm, R2 ≥ 0,8 mm und r ≥ 1 mm.The
Figur 6 zeigt einen detailliert vermassten Läufer 15, wie er für den Nummernbereich Tex 20 Anwendung finden kann. Dieser Läufer 15 entspricht in seiner Masse der ISO-Norm Nr. 2266, Serie R20, Nr. 45 (d. h. 1 000 Stück wiegen 45 Gramm) Klar ersichtlich sind die beiden kleinen Radien r und R2 = 1,2 mm beim Abschnitt 14. Der Radius des Bogens R1 ist bedeutend grösser (1,6 mm).FIG. 6 shows a
