Abstract

The eyelet in the disc (1) of a leno selvedge unit for a loom, takes the leno yarn round a common centre axis (3) through a theoretical cone-shaped entry (4) and identical exit (5) path. The theoretical cone is from a line round the centre axis, where the radius (R1) of an edge (7,8) at the entry and exit (4,5) forms a projection (9) in the yarn passage (6) with the radius (R2) between the yarn entry and exit. The eyelet (2) has a hard chrome surface layer, or is of a ceramic material.

Description

Die Erfindung betrifft eine Öse, insbesondere einer Dreherscheibe eines Rotations-Kantendrehers in einer Webmaschine zur Führung eines Dreherfadens.The invention relates to an eyelet, in particular a rotating disc of a rotary edge rotator in a weaving machine for guiding a leno thread.

Bekannt ist aus der DE 24 23 454 C2 und aus der DE 44 05 778 C1 eine Kantendrehervorrichtung bzw. ein Rotations-Kantendreher mit einer Dreherscheibe bzw. mit einer als Zahnkranz ausgebildeten Dreherscheibe, nachfolgend mit Dreherscheibe bezeichnet.
Die Dreherscheibe weist zwei diametral gegenüberliegend auf der Kreisfläche der Scheibe vorhandene Ösen bzw. Fadenführungskanäle auf.
Durch jede Öse oder jeden Führungskanal ist ein Dreherfaden führbar.Known from DE 24 23 454 C2 and from DE 44 05 778 C1 is an edge turning device or a rotary edge turning device with a rotating disk or with a rotating disk designed as a toothed ring, hereinafter referred to as rotating disk.
The rotating disc has two diametrically opposed eyelets or thread guide channels on the circular surface of the disc.
A leno thread can be passed through each eyelet or guide channel.

Der betreffende Dreherfaden erfährt auf dem Wege von der Dreherfadenspule zur Dreherkante und zwar beim Hindurchführen durch die Öse oder den Führungskanal der Dreherscheibe eine zweimalige Umlenkung von etwa 90°.
Bei der Verarbeitung von insbesondere bruchempfindlichen Dreherfäden können diese Umlenkungen zu Dreherfadenbrüchen führen.The leno thread in question experiences a two-fold deflection of approximately 90 ° on the way from the leno thread bobbin to the leno edge, namely when it is passed through the eyelet or the guide channel of the lathe disc.
When processing in particular break-sensitive leno threads, these deflections can lead to leno thread breaks.

Im Einsatzprozeß des aus der DE 44 05 777 C1 bekannten Rotations-Kantendrehers, dessen Dreherscheibe z.B. Ösen zur Dreherfadenführung aufweist, ergibt sich im Zuge der Erzeugung von Umkehrbewegungen der Dreherscheibe, nämlich aus der Bewegung zur Ausführung einer Volldrehung in der einen Richtung in die Bewegung zur Ausführung einer Volldrehung in die andere Richtung, daß der durch die Ösen geführte Dreherfaden kurzzeitig spannungslos ist.
Bei bruchempfindlichen Dreherfäden werden dann im Moment der Bewegungsumkehr der Dreherscheibe besonders an der Eingangskante und Ausgangskante der Ösen bzw. der Fadenzuführkanäle, die Dreherfäden auf Knicken beansprucht.In the application process of the rotary edge turner known from DE 44 05 777 C1, the rotating disk of which, for example, has loops for leno thread guidance, results in the course of the generation of reversing movements of the rotating disk, namely from the movement to carry out a full rotation in one direction in the movement to Execution of a full turn in the other direction so that the leno thread passed through the eyelets is briefly without tension.
In the case of break-sensitive leno threads, the leno threads are then subjected to buckling at the moment of reversal of movement of the rotating disc, particularly at the entrance edge and exit edge of the eyelets or the yarn feed channels.

Bekannte Fadenführungsösen in Dreherscheiben sind letztlich an ihren Fadenführungsflächen einem erhöhten Verschleiß ausgesetzt, was zu einem relativ frühzeitigen Austausch der Dreherscheibe oder zumindest etwaiger Ösen führt. Known thread guide eyelets in the rotating discs are ultimately on their thread guide surfaces exposed to increased wear, which leads to a relatively early replacement of the Rotary disc or at least any eyelets leads.

Außerdem sollte von Vorteil sein, wenn insbesondere bruchempfindliche Dreherfäden innerhalb der Ösen oder Fadenführungskanäle eine gewisse Fadenführung erfahren.It should also be an advantage if, in particular, fragile leno threads experience a certain thread guidance within the eyelets or thread guide channels.

Aufgabe der Erfindung ist es, in Ösen oder Fadenführungskanälen einer Dreherscheibe oder in zur Dreherscheibe technisch äquivalenten Elementen eines Rotations-Kantendrehers die Dreherfadenführung derart zu verbessern, daß die Bruchgefahr des je Öse geführten Dreherfadens reduziert wird.
Ferner besteht die Aufgabe der Erfindung darin, Vorkehrungen zu treffen, die den Dreherfaden innerhalb der Öse oder des Fadenführungskanals etwa im mittleren Bereich zwischen dem Dreherfadeneim- und -auslauf zwangsweise führen.
Des weiteren ist es Aufgabe der Erfindung, das Verschleißverhalten der Ösen oder Fadenführungskanäle zu verbessern.The object of the invention is to improve the leno thread guide in eyelets or thread guide channels of a rotating disc or in elements of a rotary edge rotator which are technically equivalent to the rotating disc in such a way that the risk of breakage of the leno thread guided per eye is reduced.
Furthermore, the object of the invention is to take precautions which forcibly guide the leno thread within the eyelet or the thread guide channel approximately in the middle region between the leno thread inlet and outlet.
Furthermore, it is an object of the invention to improve the wear behavior of the eyelets or thread guide channels.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen genannt.According to the invention the object is achieved by the features of patent claim 1. Advantageous developments of the invention are mentioned in the subclaims.

Der Vorteil der erfindungsgemäßen Lösung besteht in einer schonenden Dreherfadenführung durch die Ösen oder Führungskanäle einer Dreherscheibe, vorzugsweise bei der Verarbeitung von bruchgefährdeten Dreherfäden wie z.B. Glasseide.
Die erfindungsgemäße Lösung beschränkt sich allerdings nicht nur auf die Führung bruchgefährdeter Dreherfäden, sondern sie ist in vorteilhafter Weise für alle Dreherfaden-Typen verwendbar.The advantage of the solution according to the invention is a gentle leno thread guidance through the eyelets or guide channels of a rotating disc, preferably when processing leno threads, such as glass silk, which are at risk of breakage.
However, the solution according to the invention is not only limited to guiding leno threads that are at risk of breakage, but can be used advantageously for all types of leno threads.

Mit dem erfindungsgemäß ausgebildeten Dreherfadenein- und -auslauf wird im Falle, daß die Dreherfadendurchführungen der Dreherscheibe diese Ausbildung aufweisen, eine unmittelbare Massenreduzierung der Dreherscheibe erreicht.
Ferner ist von Vorteil, daß die Position der Mittenachse der Öse bzw. des Fadendurchführungskanals im Vergleich zur Position der Ösen bzw. der Fadendurchführungskanäle bekannter Dreherscheiben, beibehalten wird.
In aller Regel wäre nämlich eine sanftere Dreherfadenumlenkung mit einer Vergrößerung des Fadendurchgangs verbunden. Eine solche Lösung wird in der DE 25 15 961 C2 und in der DE 44 05 777 C1 dargestellt.
Damit würde aber zumindest eine Verringerung des Hubes der Dreherscheibe zur Bildung des Dreherfachs einhergehen.With the leno thread inlet and outlet designed according to the invention, in the event that the leno thread bushings of the rotator disc have this design, an immediate mass reduction of the rotator disc is achieved.
It is also advantageous that the position of the center axis of the eyelet or of the thread feed-through channel is maintained in comparison with the position of the eyelets or of the thread feed-through channels of known rotary disks.
As a rule, a gentler leno thread deflection would be associated with an increase in the thread passage. Such a solution is presented in DE 25 15 961 C2 and in DE 44 05 777 C1.
But this would go hand in hand with at least a reduction in the stroke of the rotating disk to form the rotating compartment.

Durch Hartverchromen der fädenführenden Flächen der Ösen oder durch die Herstellung der Ösen aus einem Keramikmaterial, wie es beispielsweise zur Herstellung anderer fadenführender Elemente im Textilmaschinenbau verwendet wird, kann auf das Verschleißverhalten von Ösen und Fadendurchführungskanälen in der Dreherscheibe positiv Einfluß genommen werden.
Vorteilhaft ist ferner, daß die Ösen als separate Elemente, sozusagen als Austauschelemente in die Dreherscheibe eines Rotations-Kantendrehers integrierbar sind. Die Verbindung der Ösen mit der Dreherscheibe erfolgt dabei durch allgemein übliche Maßnahmen.
In gleicher Weise können erfindungsgemäß die bislang als reine Durchgangslöcher in der Dreherscheibe vorhandenen Fadenführungskanäle ausgebildet sein, was in bestimmten Anwendungsfällen von Vorteil sein kann.Hard chromium plating of the thread-guiding surfaces of the eyelets or by the production of the eyelets from a ceramic material, such as is used for example for the production of other thread-guiding elements in textile machine construction, can have a positive influence on the wear behavior of eyelets and thread feed-through channels in the rotating disc.
It is also advantageous that the eyelets can be integrated as separate elements, so to speak as exchange elements in the rotating disc of a rotary edge rotator. The eyelets are connected to the rotating disc by generally customary measures.
In the same way, according to the invention, the thread guide channels that were previously present as pure through holes in the rotating disc can be designed, which can be advantageous in certain applications.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher beschrieben.The invention is described in more detail below using an exemplary embodiment.

Figur 1 zeigt eine Dreherscheibe 1 eines Rotations-Kantendrehers einer Webmaschine, wie dieser z.B. aus der DE 44 05 777 C1 bekannt ist.
Die technische Aufgabe, der strukturelle Aufbau und die Funktion eines Rotations-Kantendrehers sind in diesem Dokument dargestellt und beschrieben.Figure 1 shows a rotary disc 1 of a rotary edge turner of a weaving machine, as is known for example from DE 44 05 777 C1.
The technical task, the structural design and the function of a rotary edge turner are shown and described in this document.

Die Dreherscheibe 1 ist hier massearm ausgeführt, d.h. die Scheibe weist eine entsprechende Aussparung 1a auf.
Eine erste rotationssymmetrische Öse 2 ist diametral zu einer zweiten rotationssymmetrischen Öse 2 gegenüberliegend innerhalb der Dreherscheibe 1 angeordnet. Die Mittenachsen 3 beider Ösen 2 liegen, entsprechend einer dem Schußfadeneintrag notwendigen Hubhöhe h, vom Schnittpunkt der vertikalen Mittellinie 10 mit der horizontalen Mittellinie 11 im Abstand h/2 entfernt.
Die Ösen sind dabei mittels allgemein bekannter Maßnahmen mit der Dreherscheibe 1 verbunden.The rotating disc 1 is of low mass here, ie the disc has a corresponding recess 1a.
A first rotationally symmetrical eyelet 2 is arranged diametrically opposite a second rotationally symmetrical eyelet 2 within the rotating disc 1. The center axes 3 of both eyelets 2 are located at a distance h / 2 from the intersection of the vertical center line 10 with the horizontal center line 11, corresponding to a lifting height h necessary for the weft thread entry.
The eyelets are connected to the rotary disk 1 by means of generally known measures.

Denkbar ist eine innerhalb der Dreherscheibe rotierende Anordnung der Ösen 2. Damit kann der Reibungswiderstand der Ösen 2 gegenüber dem Dreherfaden minimiert werden.An arrangement of the eyelets 2 rotating within the rotating disk is conceivable the frictional resistance of the eyelets 2 to the leno thread can be minimized.

Figur 2 zeigt die geometrische Ausbildung der Öse 2 in Verbindung mit der Dreherscheibe 1 gemäß Schnitt A-A in Figur 1.
Die Öse 2 besitzt hier einen imaginären kegelförmig ausgebildeten Dreherfadeneinlauf 4 und einen im wesentlichen dazu gestaltungsidentischen Dreherfadenauslauf 5.
Der Dreherfadeneinlauf 4 und der Dreherfadenauslauf 5 ist durch einen um die Mittenachse 3 gelegenen rotationssymmetrischen Fadendurchgang 6 miteinander verbunden.FIG. 2 shows the geometric design of the eyelet 2 in connection with the rotating disc 1 according to section AA in FIG. 1.
Here, the eyelet 2 has an imaginary conical leno thread inlet 4 and a leno thread outlet 5 which is essentially identical to the design.
The leno thread inlet 4 and the leno thread outlet 5 are connected to one another by a rotationally symmetrical thread passage 6 located about the central axis 3.

Zur Verminderung des Dreherfaden-Reibungswiderstandes und der Knickbeanspruchung ist die Kante des Dreherfadeneinlaufs 4 und die des Auslaufs 5 mit einem Radius R1 versehen. Zu diesem Zweck ist auch der Fadendurchgang 6 von einem im Inneren der Öse 2 umlaufenden Vorsprung 9 gebildet, dessen freies Ende einen Radius R2 ausbildet.
Ein in Richtung des Pfeiles 12 in der Öse 2 einlaufender Dreherfaden hat dementsprechend lediglich nacheinander mit der Oberfläche der Kante 7, des Vorsprunges 9 und der Kante 8 Berührungskontakt.To reduce the leno thread frictional resistance and the buckling stress, the edge of the leno thread inlet 4 and that of the outlet 5 are provided with a radius R 1 . For this purpose, the thread passage 6 is also formed by a projection 9 running around the inside of the eyelet 2, the free end of which forms a radius R 2 .
A leno thread entering the eyelet 2 in the direction of the arrow 12 accordingly only has contact with the surface of the edge 7, the projection 9 and the edge 8 one after the other.

Die Kante 7,8 und der Vorsprung 9 besitzen einen Radius R1 bzw. R2 dessen Größe so gewählt sein sollte, daß insbesondere bruchempfindliche Garne problemlos darüber geführt werden können.
Der Winkel α und β des Dreherfadeneinlaufs- 4 bzw. -auslaufs 5 sollte jeweils nicht kleiner als 90 ° sein, wie Figur 3 zeigt.The edge 7, 8 and the projection 9 have a radius R 1 or R 2, the size of which should be selected such that, in particular, fragile yarns can be passed over it without any problems.
The angle α and β of the leno thread inlet 4 and outlet 5 should not be less than 90 °, as shown in FIG. 3.

In Figur 4 ist die Größe der Winkel α und β des Dreherfadeneinlaufs- 4 bzw. -auslaufs 5 verschieden voneinander. In Figure 4, the size of the angles α and β of the leno thread inlet 4 and outlet 5 different from each other.
