Abstract

In the weaving machine, the yarn-guide channel (3) is formed by upper (1) and lower (2) dropwires. The upper (1) and lower (2) dropwires are in different cross-sectional planes of the channel (3), the lower dropwires (2) being attached firmly to a batten (8), whilst the upper dropwires (1) have their own guide system which is so designed that, in a particular movement phase, points of the upper dropwires (1) located furthest away from the batten centre of rotation (14) provide predetermined path curves (16) which so intersect the path curves (15) of the points of the lower dropwires (2) furthest away from the batten centre of rotation (14) that the path curve (16) of the upper dropwires (1) is at a shorter distance from the batten centre of rotation (14) at the batten stop (13) than in the feed position of the batten (8). At the same time the upper dropwires (1) are mounted at a centre of rotation (17) fixed on the batten (8) and are connected to a fixed point (21) via a coupling rod (19). These measures make it possible, despite a smaller stroke of the batten, to ensure a sufficient distance between the dropwires of the yarn-guide channel during penetration into the shed. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf eine Webmaschine mit Schusseintrag durch ein strömendes Medium, bei welcher ein aus Lamellen gebildeter Führungskanal an der Weblade befestigt ist, welcher mit der Bewegung der Weblade in das aus den Kettfäden gebildete Webfach ein- und austaucht.The present invention relates to a loom with weft insertion through a flowing medium, in which a guide channel formed from lamellae is fastened to the sley, which, with the movement of the sley, dips into and out of the shed formed from the warp threads.

Zur Erzielung eines streifenfreien Gewebes müssen diese aus Lamellen gebildeten Fadenführungskanäle in einem ausreichenden Abstand von dem zuletzt angeschlagenen Schussfaden ein- und austauchen. Dieser Abstand bedingt jedoch bei bekannten Webmaschinen grosse Ladenhübe und damit grosse Webfachhöhen. Das führt zu Leistungsgrenzen infolge hoher Massenkräfte mit Verschleiss, Lärm und Energiebedarf.To achieve a streak-free fabric, these thread guide channels formed from lamellae must be inserted and removed at a sufficient distance from the last weft thread. In known weaving machines, however, this distance requires large shop lifts and thus large shed heights. This leads to performance limits due to high mass forces with wear, noise and energy requirements.

Es werden deshalb Webmaschinen angestrebt, welche bei kleinem Hub der Weblade dennoch einen ausreichenden Abstand der Lamellen des Fadenführungskanals beim Eintauchen aufweisen.Weaving machines are therefore sought which, with a small stroke of the sley, nevertheless have a sufficient distance between the lamellae of the thread guide channel when immersed.

Bekannte Vorrichtungen dieser Art gemäss der DE-OS 26 31 593 und der DE-OS 24 54 878 verwenden zur Lösung dieser Aufgabe eine getrennte Bewegung des einstückig ausgeführten Fadenführungskanals und der Weblade. Die getrennte Bewegung des gesamten Kanals muss jedoch selbst grosse Hübe aufweisen. Daraus entstehen neue Nachteile.Known devices of this type according to DE-OS 26 31 593 and DE-OS 24 54 878 use a separate movement of the one-piece thread guide channel and the sley to solve this problem. However, the separate movement of the entire channel must itself have large strokes. This creates new disadvantages.

Weitere bekannte Vorrichtungen gemäss der DE-OS 19 32 836, der DE-OS 21 60 998, der DE-OS 20 56 992, der DE-OS 28 06 301, der CH-PS 586 298 oder der CH-PS 438 167, welche mit einer der Ladebewegung überlagerten Bewegung von Teilen des Fadenführungskanals arbeiten, weisen nicht die Merkmale auf, die eine Verringerung des Ladeweges ermöglichen. Ihre Aufgabe besteht ausschliesslich im Verschliessen und Oeffnen des Fadenführungskanales.Other known devices according to DE-OS 19 32 836, DE-OS 21 60 998, DE-OS 20 56 992, DE-OS 28 06 301, CH-PS 586 298 or CH-PS 438 167, which work with a movement of parts of the thread guide channel superimposed on the loading movement do not have the features which make it possible to reduce the loading path. Your task consists exclusively in closing and opening the thread guide channel.

Eine weitere bekannte Vorrichtung gemäss der DE-OS 24 20 368 mit einer der Ladebewegung überlagerten Bewegung des gesamten Fadenführungskanales weist ebenfalls leistungs- und gewebequalitätsmindernde Nachteile auf. Der zur Anwendung kommende Fadenführungskanal ist abhängig von der Dichte des Webblattes und damit von der jeweils herzustellenden Gewebequalität, die bei Aenderungen einen Wechsel des Webblattes mit dem dazu passenden Fadenführungskanal erforderlich macht, was äusserst unwirtschaftlich ist. Zudem entsteht mit den durch das Webblatt hindurch zu bewegenden Fadenführungslamellen für die Kettfäden ein mit erhöhter Fadenreibung verengter Durchlass, der zusätzliche Materialbeanspruchung und Kettfadenbrüehe mit Webfehlern zur Folge hat.Another known device according to DE-OS 24 20 368 with a movement of the entire thread guide channel superimposed on the loading movement likewise has disadvantages which reduce performance and weave quality. The thread guide channel that is used depends on the density of the reed and thus on the fabric quality to be produced in each case, which changes the reed in the event of changes matching thread guide channel required, which is extremely uneconomical. In addition, the thread guide lamella for the warp threads to be moved through the reed creates a passage constricted with increased thread friction, which results in additional material stress and warp thread broth with weaving defects.

Es ist nun Aufgabe der vorliegenden Erfindung, eine Webmaschine der vorgenannten Art zu schaffen, welche unter Vermeidung der Nachteile der bekannten Anordnungen gestattet, die vorzitierten Anforderungen voll zu erfüllen.It is an object of the present invention to provide a weaving machine of the aforementioned type which, while avoiding the disadvantages of the known arrangements, allows the requirements cited above to be fully met.

Dies wird erfindungsgemäss dadurch erreicht, dass der Kanal durch Ober- und Unterlamellen gebildet ist, wobei die Ober- und die Unterlamellen in unterschiedlichen Querschnittsebenen des Kanals liegen und wobei die Unterlamellen fest an einer Weblade angebracht sind, während die Oberlamellen ein eigenes Führungssystem besitzen, welches so ausgebildet ist, dass, jeweils in einer Bewegungsphase, am weitesten vom Ladedrehpunkt entfernt liegende Punkte der Oberlamellen vorgegebene Bahnkurven ergeben, die die Bahnkurven der am weitesten vom Ladedrehpunkt entfernten Punkte der Unterlamellen so schneiden, dass die Bahnkurve der Oberlamellen beim Webladeanschlag einen geringeren Abstand zum Ladedrehpunkt aufweist, als bei der Eintragsstellung der Weblade.This is achieved according to the invention in that the channel is formed by upper and lower lamellae, the upper and lower lamellae being in different cross-sectional planes of the channel and the lower lamellae being fixedly attached to a sley, while the upper lamellae have their own guide system, which is designed in such a way that, in each movement phase, points of the top lamella furthest away from the loading pivot point result in predetermined trajectory curves which are the furthest Cut the points of the lower slats at a distance from the loading point of rotation so that the path curve of the upper slats is less close to the loading point of rotation at the web loading stop than at the position of the sley loading.

Hierbei kann die Ausgestaltung vorteilhaft so sein, dass die Oberlamellen an einem an der Weblade festen Drehpunkt gelagert sind und über eine Koppelstange mit einem ortsfesten Punkt verbunden sind.In this case, the configuration can advantageously be such that the upper slats are mounted at a pivot point fixed to the sley and are connected to a fixed point via a coupling rod.

Dadurch, dass nunmehr eine separate Bewegung eines Teiles der den Kanal bildenden Führungslamellen erfolgt, sind geringe Lamellenhübe bei, geringer Lamellenmasse möglich. Ferner kann auf eine mechanische Umschliessung des Kanals verzichtet werden. Dieser, nach der Webblattseite hin offene, in der Ebene der Kanalachse erfindungsgemäss zweiteilig ausgeführte Kanal wird dabei durch die den neuesten Erkenntnissen folgende Strahllage der über die Webbreite verteilt angeordneten Strömungsaustrittsöffnungen bei monostabiler Fadenführung dynamisch verschlossen. Die Strömungsaustrittsöffnungen liegen dazu nahe an der blattseitigen Kanalöffnung und sind so gerichtet, dass sie in geschlossenem Zustand des Fadenführungskanales bei ruhender Weblade optimale Bedingungen für einen von Sekundärströmungen freien, sicheren und energiesparenden Schusseintrag ergeben.The fact that a part of the guide slats forming the channel now moves separately means that small slat strokes are possible with a low slat mass. Furthermore, there is no need to mechanically enclose the channel. This channel, which is open in the plane of the channel axis according to the invention and is open towards the reed side, is closed dynamically by the jet position following the latest knowledge of the flow outlet openings arranged over the weaving width with monostable thread guidance. The flow outlet openings are close to the leaf-side channel opening and are directed so that they in the closed state of the thread guide channel with the sley closed, result in optimal conditions for a safe, energy-saving weft insertion free of secondary currents.

Durch die Verkürzung des Ladehubes und der Webfachhöhe lässt sich die Drehzahl und damit die Webleistung einer erfindungsgemäss ausgebildeten Webmaschine ohne ansteigenden Energiebedarf und Verschleissanfälligkeit beträchtlich erhöhen. Zudem wird das Material der Webkette durch die kürzeren Hub- und Reibungswege von Webblatt und Schaftlitzen, trotz steigender Drehzahl, vermindert beansprucht. Auch wird der Lärmpegel durch höhere Frequenz und geringere Massenkräfte günstig beeinflusst.By shortening the loading stroke and the height of the shed, the speed and thus the weaving performance of a weaving machine designed according to the invention can be increased considerably without increasing energy requirements and susceptibility to wear. In addition, the material of the warp is less stressed due to the shorter stroke and friction paths of the reed and heald strands, despite increasing speed. The noise level is also favorably influenced by higher frequencies and lower mass forces.

In den Figuren 1, 2 und 3 ist eine erfindungsgemässe Anordnung an einer Webmaschine mit einer Weblade 8, die bei 14 fest gelagert ist, mit einem Webblatt 6, den Webschäften 12, den Kettfäden 9 und 10, dem Webfach 11, dem Schussfadenanschlag und Gewebe 13 und dem aus Oberlamellen 1 und Unterlamellen 2 gebildeten zweiteiligen Fadenführungskanal 3 dargestellt.In Figures 1, 2 and 3, an arrangement according to the invention on a weaving machine with a sley 8, which is fixed at 14, with a reed 6, the heald frames 12, the warp threads 9 and 10, the shed 11, the weft stop and fabric 13 and the two-part thread guide channel 3 formed from upper lamellae 1 and lower lamellae 2.

Figur 1 zeigt eine Seitenansicht der Anordnung in Eintragssstellung mit dem Schussfaden 7 sowie die Strömungsaustrittsöffnung 4, mit der Achse des Austrittsstrahles 5, welche Achse nahe der blattseitigen weiten Kanalöffnung liegt und so gerichtet ist, dass diese zur Ebene des Webblattes 6 stromabwärts einen grösser werdenden Abstand und zur Kanalaehse 3 stromabwärts einen kleiner werdenden Abstand aufweist, wobei die Achse des Austrittstrahles 5 die Hüllfläche derjenigen Seite des Kanals 3 nicht schneidet, auf der sich die Strömungsaustrittsöffnungen 4 befinden.Figure 1 shows a side view of the arrangement in the entry position with the weft thread 7 and the flow outlet opening 4, with the axis of the outlet jet 5, which axis is close to the wide channel opening on the blade side and is directed such that it becomes a greater distance downstream from the plane of the reed 6 and has a decreasing distance from the channel axis 3 downstream, the axis of the outlet jet 5 not intersecting the envelope surface of that side of the channel 3 on which the flow outlet openings 4 are located.

Mit dieser erfindungsgemässen Anordnung wird der offene Kanal 3 blattseitig dynamisch verschlossen und eine monostabile, energiesparende Fadenführung erreicht.With this arrangement according to the invention, the open channel 3 is dynamically closed on the leaf side and monostable, energy-saving thread guidance is achieved.

Figur 2 zeigt die Anordnung während des Schussfadenanschlages, wobei der erfindungsgemäss zweiteilig ausgeführte Schussfadenkanal 3 geöffnet ist und durch das den Oberlamellen 1 erfindungsgemäss zugeteilte Führungssystem synchron mit der Ladebewegung eine Bahnkurve 16 verliehen wird, die von der Bahnkurve 15 der Unterlamellen 2 derart abweicht und sich die Bahnkurven 15 und 16 schneiden, dass zwischen dem Sehussfadenanschlag mit Gewebe 13 bis zum Eintauchen des so getrennt bewegten Teiles 1 des Kanals 3 ein Abstand gemäss der Strecke A erreicht wird. Durch diesen ausreichenden Abstand A wird trotz kurzem Ladehub die Erzielung eines streifenfreien Gewebes mit geringer Fadenreibung garantiert.FIG. 2 shows the arrangement during the weft thread stop, the weft thread channel 3, which is designed in two parts according to the invention, being opened and by the guide system assigned to the upper lamellae 1, a path curve 16 is imparted synchronously with the loading movement, which deviates from the path curve 15 of the lower lamellae 2 in such a way that it deviates Cut trajectories 15 and 16 so that a distance according to the distance A is reached between the optic thread stop with fabric 13 until the part 1 of the channel 3 moved so separately is immersed. This sufficient distance A ensures that streak-free fabric with low thread friction is achieved despite a short loading stroke.

Weiter wird den Oberlamellen 1 über das zugeteilte Führungssystem die Bahnkurve 16 derart verliehen, indem die Oberlamellen 1 über eine Traverse 22 mit dem Hebel 18, der bei 17 an der Lade gelagert ist, fest verbunden sind und der Hebel 18 über die,zwischen dem Drehpunkt 20 und dem ortsfesten Punkt 21 befindliche Koppelstange 19 mit der Ladebewegung bewegt wird.Furthermore, the upper slats 1 are given the trajectory 16 via the assigned guide system in such a way that the upper slats 1 are firmly connected via a cross member 22 to the lever 18, which is mounted on the drawer at 17, and the lever 18 via, between the pivot point 20 and the fixed point 21 located coupling rod 19 is moved with the loading movement.

Figur 3 zeigt die erfindungsgemässe Anordnung an der Webmaschine während der Bewegung in das Webfach 11.Figure 3 shows the arrangement according to the invention on the Loom while moving into the shed 11.

In den Figuren 4, 5, 6 und 7 ist ein zweiteiliger Fadenführungskanal 3 in geschlossenem Zustand von vier Seiten her dargestellt, der aus den Oberlamellen 1 und den Unterlamellen 2 gebildet ist, wobei die obere und vordere Hüllfläche aus den Lamellen 1 und die untere Hüllfläche aus den Lamellen 2 entsteht. Der aus beiden, in verschiedenen Kanalquerschnitten liegenden Lamellenarten 1 und 2 gebildete Kanal 3 ist auf der Webblattseite weit offen.In Figures 4, 5, 6 and 7, a two-part thread guide channel 3 is shown in the closed state from four sides, which is formed from the upper lamellae 1 and the lower lamellae 2, the upper and front envelope surface from the lamellae 1 and the lower envelope surface arises from the slats 2. The channel 3 formed from both types of lamella 1 and 2 lying in different channel cross sections is wide open on the reed side.

Der Fadenführungskanal 3 besteht aus Lamellen mit Strömungsaustrittsöffnungen 4 und solchen ohne, wobei sich der Querschnitt des Kanals 3 jeweils nach einer Lamelle mit Strömungsaustrittsöffnung 4 gemäss den Figuren 4, 5 und 6 stufenförmig erweitert und sich dann in Eintragsrichtung bis zur nächsten Lamelle mit Strömungsaustrittsöffnung 4 verengt.The thread guide channel 3 consists of lamellae with flow outlet openings 4 and those without, the cross section of the channel 3 widening in steps after a lamella with flow outlet opening 4 according to FIGS. 4, 5 and 6 and then narrowing in the entry direction to the next lamella with flow outlet opening 4 .

In den Figuren 8 und 9 ist die erfindungsgemässe Anordnung eines zweiteiligen Fadenführungskanales 3 in Draufsicht und Seitenansicht, jedoch in geöffnetem Zustand gemäss Figur 2 während des Schussanschlages 13 dargestellt.FIGS. 8 and 9 show the arrangement according to the invention of a two-part thread guide channel 3 in top view and side view, but in the open state according to FIG. 2 during the weft stop 13.

Als weiterer Vorteil der vorbeschriebenen Anordnung an einer Webmaschine ist die feste Verbundenheit der Strömungsaustrittsöffnungen 4 mit ihren Zuführungen zusammen mit den Unterlamellen 2 an der Weblade 8 zu sehen, weil dadurch ein präzises und stabiles Richten des Transportstrahles 5 gegeben ist.A further advantage of the arrangement described above on a weaving machine is the firm connection of the flow outlet openings 4 with their feeds together with the lower lamellae 2 on the sley 8, because this gives the transport jet 5 a precise and stable direction.
