Description

Die Erfindung betrifft eine Luftdüsen-Webmaschine mit einer auf einem Jacquard-Gerüst angeordneten Jacquard-Maschine.The invention relates to an air jet loom with a jacquard machine arranged on a jacquard frame.

Eine Luftdüsen-Webmaschine mit einer Jacquard-Maschine ist bereits bekannt, siehe auch EP 0 087 519.An air jet weaving machine with a jacquard machine is already known, see also EP 0 087 519.

Die Jacquard-Maschine sitzt vertikal mittig genau über der vorgesehenen Einzugsbreite des Webblattes, so daß eine symmetrische Ausrichtung der Harnischschnüre gegeben ist.The jacquard machine sits vertically in the middle, exactly above the intended feed width of the reed, so that there is a symmetrical alignment of the harness cords.

Bei einer Veränderung der Einzugsbreite wurde das Webblatt entsprechend angepaßt. So wurde bei einer Verkleinerung der Einzugsbreite ein entsprechend verkürztes Webblatt verwendet.If the feed width was changed, the reed was adjusted accordingly. A correspondingly shortened reed was used to reduce the feed width.

Um wieder eine symmetrische Ausrichtung auf ein verkleinertes Webblatt zu erreichen, mußte man bislang die gesamte Jacquard-Maschine verschieben, um derart eine symmetrische Verteilung der Harnischschnüre auch bei verringerter Einzugsbreite zu erreichen.In order to achieve a symmetrical alignment on a reduced reed again, the entire jacquard machine had to be moved so far in order to achieve a symmetrical distribution of the harness cords even with a reduced feed width.

Damit war jedoch nachteilig ein großer Umrüstaufwand verbunden.However, this was disadvantageously associated with a large changeover effort.

Aus der FR-PS 2 184 052 und der US-PS 3,908,710 ist eine Luftdüsen-Webmaschine bekannt, die nicht mit einer Jacquard-Maschine in Verbindung steht. Hier ist die Fangseite in Richtung auf eine veränderte Einzugsbreite des Webblattes nachführbar. Die Schußseite hingegen ist feststehend angeordnet.From FR-PS 2 184 052 and US-PS 3,908,710 an air jet weaving machine is known which is not connected to a jacquard machine. Here the catch side can be adjusted in the direction of a changed feed width of the reed. The weft side, however, is fixed.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Luftdüsen-Webmaschine, die mit einer Jacquard-Maschine zusammenarbeitet und wobei das Webblatt zentrisch zur Jacquard-Maschine ausgerichtet ist, steuerbare Funktionselemente der Schußseite und der Fangseite dem Webblatt, das eine bestimmte Einzugsbreite besitzt, nachführbar auszubilden und dabei die Zeiteinstellung der steuerbaren Funktionselemente innerhalb eines Webzyklus aufrechtzuerhalten. Die Aufgabe ist durch die Merkmale des Anspruches 1 gelöst.The invention is based on the object, in an air jet weaving machine that works together with a jacquard machine and the reed is centered on the jacquard machine, controllable functional elements of the The weft side and the catch side of the reed, which has a certain feed width, to be designed to be traceable and at the same time to maintain the time setting of the controllable functional elements within a weaving cycle. The object is solved by the features of claim 1.

Durch eine solche Lösung wird eine bedienungsfreundliche Anordnung der Schußund Fangseite erreicht.
Darüber hinaus gilt für die symmetrische Ausrichtung des Webblattes einer Luftdüsen-Webmaschine gegenüber der Jacquard-Maschine der Vorteil, daß das Gewebe über die Ausbreitwalze symmetrisch abläuft, wodurch ein schonender Gewebeabzug gewährleistet wird.
Vorteilhaft ist ferner, daß bei Verwendung von Webschäften für die Fachbildung die Schäfte symmetrisch belastet sind, wodurch bei höheren Webfrequenzen die Schwingungen der Schäfte reduziert werden.With such a solution, a user-friendly arrangement of the weft and catch side is achieved.
In addition, for the symmetrical alignment of the reed of an air jet loom compared to the jacquard machine, the advantage is that the fabric runs symmetrically over the spreading roller, which ensures gentle fabric removal.
It is also advantageous that when using heald frames for shed formation the shafts are loaded symmetrically, whereby the vibrations of the shafts are reduced at higher weaving frequencies.

Erfindungsgemäß ist ferner vorgesehen, daß sich über die gesamte Maschinenbreite eine synchron angetriebene Steuerwelle erstreckt, und längs dieser Steuerwelle sämtliche zu verschiebende, steuerbare Funktionselemente an der Schußseite und an der Fangseite der Einzugsbreite nachgeführt werden können und dabei stets synchron von dieser Steuerwelle beaufschlagt werden.According to the invention it is further provided that a synchronously driven control shaft extends over the entire machine width, and along this control shaft all controllable functional elements to be moved can be tracked on the weft side and on the catch side of the feed width and are always acted upon synchronously by this control shaft.

Hierbei ergibt sich der wesentliche Vorteil, daß die Zeiteinstellung der steuerbaren Funktionselemente innerhalb eines Webzyklus erhalten bleibt. Im Gegensatz dazu erstreckte sich bei den bisher bekannten Maschinen die Steuerwelle nicht über die gesamte Maschinenbreite. Daher war die Synchronisation der verschiedenen Funktionselemente an einer mit einer Jacquard-Maschine in Verbindung stehenden Luftdüsen-Webmaschine relativ schwierig.The main advantage here is that the time setting of the controllable functional elements is retained within a weaving cycle. In contrast to this, the control shaft did not extend over the entire machine width in the previously known machines. It was therefore relatively difficult to synchronize the various functional elements on an air-jet weaving machine connected to a jacquard machine.

Im Folgenden wird die Erfindung anhand von lediglichen einen Ausführungsweg darstellende Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile der Erfindung hervor.In the following, the invention is explained in more detail with the aid of only drawings that illustrate one embodiment. Here, from the drawings and their description, further features and advantages of the invention that are essential to the invention emerge.

In Figur 1 ist schematisiert dargestellt, daß eine Jacquard-Maschine 1 mittig auf einem Jacquard-Gerüst 2 angeordnet ist und mit einer Luftdüsen-Webmaschine 48 zusammenwirkt.FIG. 1 shows schematically that a jacquard machine 1 is arranged centrally on a jacquard frame 2 and interacts with an air jet weaving machine 48.

In Figur 1 ist erkennbar, daß die von der Jacquard-Maschine 1 ausgehenden Harnischschnüre 3 symmetrisch in Richtung des Webblattes 4 der Luftdüsen-Webmaschine 48 geführt sind.It can be seen in FIG. 1 that the harness cords 3 emanating from the jacquard machine 1 are guided symmetrically in the direction of the reed 4 of the air jet weaving machine 48.

Will man nun die Einzugsbreite 9 des Webblattes 4 der Luftdüsen-Webmaschine 48 verändern, indem man z.B. eine verringerte Einzugsbreite 10 wünscht, so muß man ein entsprechend kürzeres Webblatt 5 verwenden.If you now want to change the feed width 9 of the reed 4 of the air jet weaving machine 48, for example by if a reduced feed width 10 is desired, then a correspondingly shorter reed 5 must be used.

Das längere Webblatt 4 wird also durch ein kürzeres Webblatt 5 ausgetauscht.The longer reed 4 is thus replaced by a shorter reed 5.

Erfindungsgemäß wird nun das kürzere Webblatt 5 genau symmetrisch und mittig unter der Jacquard-Maschine 1 angeordnet, ohne dabei die Jacquard-Maschine 1 auf dem Jacquard-Gerüst 2 verschieben zu müssen.According to the invention, the shorter reed 5 is now arranged exactly symmetrically and centrally under the jacquard machine 1 without having to move the jacquard machine 1 on the jacquard frame 2.

Anstatt des Austausches des längeren Webblattes 4 durch ein kürzeres Webblatt 5 ist es in einer anderen Ausführung möglich, das Webblatt 4 so zu kürzen, daß es der Länge des Webblattes 5 entspricht.Instead of replacing the longer reed 4 with a shorter reed 5, it is possible in another embodiment to shorten the reed 4 so that it corresponds to the length of the reed 5.

Wegen der verkürzten Länge des Webblattes 5 ist es nun erforderlich, sowohl die Schußseite 6 in Pfeilrichtung 12 als auch die Fangseite 7 in Pfeilrichtung 14 dem entsprechenden Webblatt 4 bzw. 5 nachzuführen.Because of the shortened length of the reed 5, it is now necessary to track both the weft side 6 in the arrow direction 12 and the catch side 7 in the arrow direction 14 of the corresponding reed 4 or 5.

Aus dem vorher erwähnten Stand der Technik ist also nur bekannt, die Schußseite 6 stationär angeordnet zu belassen und die Fangseite 7 in Pfeilrichtung 14 nachzuführen und die Differenz 15 an der Fangseite zwischen dem kürzeren Webblatt 5 und dem längeren Webblatt 4 auszugleichen.
Bei einer Luftdüsen-Webmaschine, die mit einer Jacquard-Maschine in Verbindung steht, ergeben sich dabei aber die vorstehend erwähnten Nachteile.From the aforementioned prior art it is only known to leave the weft side 6 arranged in a stationary manner and to track the catch side 7 in the direction of arrow 14 and to compensate for the difference 15 on the catch side between the shorter reed 5 and the longer reed 4.
In the case of an air-jet weaving machine which is connected to a jacquard machine, however, the disadvantages mentioned above arise.

Gemäß der Erfindung wird nun die Schußseite 6 in Pfeilrichtung 12 zusätzlich nachgeführt, um die Differenz 13 zwischen dem längeren Webblatt 4 und dem kürzeren Webblatt 5 auszugleichen.According to the invention, the weft side 6 is now additionally tracked in the direction of the arrow 12 in order to compensate for the difference 13 between the longer reed 4 and the shorter reed 5.

Gemäß der Erfindung müssen nun die an der Schußseite 6 angeordneten und steuerbaren Funktionselemente in Längsrichtung, nämlich in Pfeilrichtung 12 (und in Gegenrichtung dazu) verstellbar an der Luftdüsen-Webmaschine 48 angeordnet sein.According to the invention, the functional elements arranged and controllable on the weft side 6 must now be arranged on the air jet weaving machine 48 so as to be adjustable in the longitudinal direction, namely in the direction of the arrow 12 (and in the opposite direction).

Die Figuren 2 bis 4 zeigen weitere Einzelheiten der Längsverstellung.Figures 2 to 4 show further details of the longitudinal adjustment.

In Figur 2 ist dargestellt, daß eine Hauptdüse 16 aus einem Halter 17 besteht, in dem ein oder mehrere Düsenrohre 18 angeordnet sind, die an ihrer Vorderseite eine Fadenaustrittsöffnung 19 besitzen.FIG. 2 shows that a main nozzle 16 consists of a holder 17 in which one or more nozzle tubes 18 are arranged, which have a thread outlet opening 19 on their front side.

Der Halter 17 ist hierbei in den Pfeilrichtungen 12 längs verschiebbar an der Blattleiste 46 angeordnet.The holder 17 is arranged in the arrow directions 12 to be longitudinally displaceable on the sheet bar 46.

Hierzu sind in der Blattleiste 46 Bohrungen 21 vorgesehen, in welche entsprechende Schrauben 23 einschraubbar sind. Die Schrauben 23 durchgreifen jeweils im Halter 17 in Längsrichtung angeordnete Langlöcher 22, so daß der gesamte Halter 17 im Bereich des Langloches 22 auf der Blattleiste 46 verschiebbar ist.For this purpose, holes 21 are provided in the sheet bar 46, into which corresponding screws 23 can be screwed. The screws 23 each pass through elongated holes 22 arranged in the longitudinal direction in the holder 17, so that the entire holder 17 can be moved in the region of the elongated hole 22 on the sheet bar 46.

Um größere Verschiebungsbereiche zu gewährleisten, ist es vorgesehen, daß die Schrauben 23 vollständig entfernt und in andere Bohrungen 21 eingeschraubt werden.In order to ensure larger ranges of displacement, it is provided that the screws 23 are completely removed and screwed into other bores 21.

In Figur 2 ist noch dargestellt, daß die Schußfäden 49 der Hauptdüse 16 zugeführt werden.FIG. 2 also shows that the weft threads 49 are fed to the main nozzle 16 will.

Figur 3 zeigt Einzelheiten des Synchron-Antriebes der einzelnen Elemente.Figure 3 shows details of the synchronous drive of the individual elements.

Hierbei ist von wesentlicher Bedeutung, daß sich die Steuerwelle 24 über die gesamte Breite der Luftdüsen-Webmaschine 48 erstreckt. Damit ist der wesentliche Vorteil verbunden, daß alle steuerbaren Funktionselemente der Schußseite 6 und der Fangseite 7 längs dieser Steuerwelle verschiebbar sind und stets synchron von dieser Steuerwelle angetrieben werden.It is essential that the control shaft 24 extends over the entire width of the air jet loom 48. This has the essential advantage that all controllable functional elements of the weft side 6 and the catching side 7 can be moved along this control shaft and are always driven synchronously by this control shaft.

Dies ist neu gegenüber dem Stand der Technik, denn bisher war auf der Schußseite 6 nur eine relativ kurze Steuerwelle vorhanden, die es nicht ermöglichte, die an der Schußseite angeordneten, steuerbaren Funktionselemente durchgehend längs der Steuerwelle zu verschieben.This is new compared to the prior art, because previously there was only a relatively short control shaft on the weft side 6, which did not make it possible to continuously move the controllable functional elements arranged on the weft side along the control shaft.

In Figur 3 ist gezeigt, daß die Steuerwelle 24 über Lager 25,26 drehbar auf Lagerböcken 27 am Gestell 50 der Luftdüsenwebmaschine gelagert ist.In FIG. 3 it is shown that the control shaft 24 is rotatably mounted on bearings 25 on the frame 50 of the air jet weaving machine via bearings 25, 26.

Der Drehantrieb der Steuerwelle 24 erfolgt hierbei über ein Zahnradgetriebe 31,32.The rotary drive of the control shaft 24 takes place here via a gear transmission 31, 32.

In Figur 3 ist beispielhaft ein verschiebbarer Scherenantrieb dargestellt. Es versteht sich von selbst, daß die anderen steuerbaren Funktionselemente der Schußseite durch gleichwirkende Elemente gesteuert werden und verschiebbar sind.A displaceable scissor drive is shown as an example in FIG. It goes without saying that the other controllable functional elements on the weft side are controlled by elements having the same effect and are displaceable.

Gemäß Figur 3 ist der für den Antrieb der in Figur 4 dargestellten Schere 36 vorgesehene Exzenter 28 drehfest mit einer Büchse 29 verbunden, die ihrerseits über eine Paßfeder 30 in Längsrichtung auf der Steuerwelle 24 verschiebbar ist.According to FIG. 3, the eccentric 28 provided for driving the scissors 36 shown in FIG. 4 is connected in a rotationally fixed manner to a bush 29, which in turn can be displaced in the longitudinal direction on the control shaft 24 via a feather key 30.

In Figur 4 sind weitere Einzelheiten des Antriebes der Schere 36 dargestellt.In Figure 4, further details of the drive of the scissors 36 are shown.

Im Lagerbock 27 ist gemäß Fig. 3 die Steuerwelle 24 drehbar gelagert, wobei man erkennt, daß der Exzenter 28 auf einem einseitig im Lager 38 schwenkbar am Lagerbock 27 gelagerten Schwenkhebel 37 wirkt, der federbelastet über die Feder 39 kraftschlüssig auf die Schere 36 wirkt.3, the control shaft 24 is rotatably mounted, wherein it can be seen that the eccentric 28 acts on a pivotally mounted on one side in the bearing 38 on the bearing block 27 pivot lever 37 which acts spring-loaded on the spring 39 non-positively on the scissors 36.

Hierbei wird die eine Schneide 40 schwenkbar angetrieben, während die andere Schneide 40 fest am Lagerbock 27 befestigt ist.Here, one cutting edge 40 is pivotally driven, while the other Cutting edge 40 is firmly attached to the bearing block 27.

Entsprechend der Darstellung in Fig. 3 ist damit die gesamte Schere 26 senkrecht zur Zeichenebene der Fig. 4 längs der Steuerwelle 24 verschiebbar.According to the illustration in FIG. 3, the entire scissors 26 can thus be displaced along the control shaft 24 perpendicular to the plane of FIG. 4.

Ferner ist erkennbar, daß die Ketffäden 41 durch die Litzenaugen 43 der parallel angeordneten und einen gegenseitigen Abstand voneinander einnehmenden Litzen 42 geführt werden, wobei zwischen dem oberen und dem unteren Ketffaden 41 das Schußfaden-Eintragssystem angeordnet ist, welches aus dem Webblatt 4 mit einem Schußfadeneintragskanal 44, dem Stafettendüsen 45 zugeordnet sind, und der Hauptdüse 16 besteht, wobei die genannten Teile auf der Blattleiste 46 montiert sind, die ihrerseits auf einer Blattstütze 47 befestigt ist.It can also be seen that the warp threads 41 are guided through the heddle eyes 43 of the strands 42 arranged in parallel and spaced apart from one another, the weft insertion system being arranged between the upper and the lower warp thread 41, which system consists of the reed 4 with a weft insertion channel 44, which are associated with relay nozzles 45, and the main nozzle 16, the parts mentioned being mounted on the sheet bar 46, which in turn is fastened on a sheet support 47.

Das fertiggestellte Gewebe 34 wird über die Ausbreitwalze 33 in Pfeilrichtung 35 abgezogen.The finished fabric 34 is drawn off over the spreading roller 33 in the direction of arrow 35.

Wichtig bei der vorliegenden Erfindung ist also, daß die Schußseite 6 nach Fig. 1 in den Pfeilrichtungen 12 verschiebbar angeordnet ist, so daß damit eine symmetrische Ausrichtung der Einzugsbreite bei Luftdüsen-Webmaschinen, die mit einer Jacquard-Maschine in Verbindung stehen, gewährleistet ist. Damit ist sichergestellt, daß das Gewebe über die Ausbreitwalze 33 symmetrisch abläuft, wodurch einen schonender Gewebeabzug gewährleistet ist.It is therefore important in the present invention that the weft side 6 according to FIG. 1 is arranged to be displaceable in the direction of the arrows 12, so that a symmetrical alignment of the feed width in air jet looms which are connected to a jacquard machine is ensured. This ensures that the fabric runs symmetrically over the spreading roller 33, which ensures gentle fabric removal.

Der schonende Gewebeabzug wird durch die jetzt mögliche symmetrische Führung der Harnischschnüre 3 erreicht.The gentle tissue removal is achieved by the symmetrical guidance of the harness cords 3 now possible.

Sofern man eine Jacquard-Maschine 1 mit Webschäften (hier nicht zeichnerisch dargestellt) kombiniert, besteht der weitere Vorteil, daß diese Webschäfte symmetrisch belastet werden, wodurch höhere Webfrequenzen erzielbar sind und Schaftschwingungen vermieden werden.If you combine a jacquard machine 1 with heald frames (not shown here in the drawing), there is the further advantage that these heald frames are loaded symmetrically, as a result of which higher weave frequencies can be achieved and shaft vibrations are avoided.
