Definitions
- 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.
- 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.
- these deflections can lead to leno thread breaks.
- 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.
- 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.
- 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 central 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.
- the advantage of the solution according to the invention is a gentle leno thread guidance through the eyelets or guide channels of a rotating disk, preferably when processing leno threads, such as glass silk, which are at risk of breakage.
- 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.
- Hard chrome plating of the thread-guiding surfaces of the eyelets or by manufacturing the eyelets from a ceramic material, such as is used, for example, to produce 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.
- 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.
- 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 point of 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.
- FIG. 2 shows the geometric design of the eyelet 2 in connection with the rotating disc 1 according to section AA in FIG. 1.
- the eyelet 2 here 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.
- the edge of the leno thread inlet 4 and that of the outlet 5 are provided with a radius R 1 in order to reduce the leno thread friction resistance and the buckling stress.
- 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.
- the edge 7, 8 and the projection 9 have a radius R 1 or R 2, the size of which should be selected so that, in particular, fragile yarns can be passed over it without any problems.
- the angle ⁇ and ⁇ of the leno thread inlet 4 and outlet 5 should not be less than 90 °, as shown in FIG. 3.

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, die als nächstliegender Stand der Technik angesehen werden, 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.It is known from DE 24 23 454 C2 and from DE 44 05 778 C1, which are considered to be the closest prior art, an edge-turning device or a rotary edge-turning device with a rotating disk or with a rotating disk designed as a ring gear, hereinafter with a rotating disk designated.
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 Dreherfadenein- 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 central 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
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 disk, 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 chrome plating of the thread-guiding surfaces of the eyelets or by manufacturing the eyelets from a ceramic material, such as is used, for example, to produce 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.
