Description

Die Erfindung betrifft eine Greiferwebmaschine gemäss Oberbegriff des Anspruches 1.The invention relates to a rapier weaving machine according to the preamble of claim 1.

Greiferwebmaschinen sind in grosser Zahl, so beispielsweise aus der DE-A-23 44 123, bekannt, dabei werden Greifer formschlüssig in ein Webfach eingeschoben bzw. wieder herausgezogen. Es wird zwischen Greiferwebmaschinen mit einseitigen und solchen mit zweiseitigen Greifern unterschieden, wobei einseitige Greifer das ganze Webfach durchlaufen. Bei zweiseitigen Greifern wird von jeder Gewebeseite aus ein Greifer in das Webfach eingebracht, wobei ein Greifer als Bringer von einer Seite einen Schussfaden einzieht, ihn in der Mitte des Webfaches an den Nehmer-Greifer abgibt, der dann den Schussfaden vollständig aus dem Webfach herauszieht.Gripper weaving machines are known in large numbers, for example from DE-A-23 44 123, grippers are positively inserted or pulled out of a shed. A distinction is made between rapier weaving machines with one-sided and those with double-sided rapiers, with one-sided rapiers running through the entire shed. In the case of double-sided rapiers, a rapier is inserted into the shed from each side of the fabric, a rapier pulling in a weft thread from one side, delivering it in the middle of the shed to the taker gripper, who then pulls the weft thread completely out of the shed.

Die EP-A-0 266 286 (veröffentlicht 04.05.88) beschreibt eine solche Greiferwebmaschine mit einer während des Webens betätigbare Betätigungsvorrichtung für den Öffner, um eine Auflaufschiene mit einem Nocken der Schussfaden-Klemme zu deren Öffnen in Eingriff zu bringen. Aufgabe dieser Betätigungsvorrichtung ist es, die Auflaufschiene nur dann zum Eingriff zu bringen, wenn die Schussfaden-Klemme geöffnet werden soll, d.h. beim Aufnehmen oder Abgeben eines Schussfadens. In der jeweils anderen Bewegungsphase der Schussfaden-Klemme, d.h. beim Leerhub, wird die Auflaufschiene zurückgenommen, um den Bewegungsvorgang des Greifers nicht zu beeinträchtigen. Eine Einstellung des Abstandes der Offenstellung der Klemme vom Webfach oder der Webkante ist nicht vorgesehen und auch nicht möglich, da die Stellvorrichtung die Auflaufschiene nur in zwei genau festgelegte Stellungen bringen kann, d.h. entweder EIN oder AUS.EP-A-0 266 286 (published 04.05.88) describes such a rapier weaving machine with an actuating device for the opener which can be actuated during weaving in order to engage a run-on rail with a cam of the weft thread clamp in order to open it. The task of this actuating device is to bring the run-up rail into engagement only when the weft thread clamp is to be opened, ie when picking up or dispensing a weft thread. In the other phase of movement of the weft thread clamp, ie during the idle stroke, the run-up rail is withdrawn so as not to impair the movement of the hook. An adjustment of the distance of the open position of the clamp from the shed or the selvedge is not provided and also not possible, since the adjusting device can only bring the run-up rail into two precisely defined positions, ie either ON or OFF.

Aufgabe der Erfindung ist es, solche Greiferwebmaschinen dahingehend weiterzuverbessern, dass der Abstand der Offenstellung des Greifers vom Webfach bzw. der Webkante zur Schussfadenfreigabe nach dem Einziehen des Schussfadens durch das Webfach während des Betriebes der Greiferwebmaschine einstellbar ist.The object of the invention is to further improve such rapier weaving machines in such a way that the distance of the open position of the rapier from the shed or the selvedge to the weft thread release after the weft thread is drawn in by the shed can be adjusted during operation of the rapier weaving machine.

Die Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The object is achieved according to the invention by the characterizing features of claim 1.

Die Stellvorrichtung der vorliegenden Art wird nicht zum EIN-oder AUS-schalten des Öffners der Schussfaden-Klemme verwendet, sondern bleibt sowohl beim Arbeitshub wie beim Leerhub des Greifers im Einsatz. Im erfindungsgemässen Falle ist die Stellvorrichtung mit einer Regelvorrichtung ausgestattet, mit der während des Webens der Abstand der Offenstellung der Klemme vom Webfach oder der Webkante einstellbar ist. Mit Hilfe der Regelvorrichtung ist es möglich, den Abstand der Offenstellung der Klemme vom Webfach bzw. der Webkante nach dem Durchziehen des Schussfadens durch das Webfach, auf die jeweiligen Betriebsbedingungen einzustellen. So ist es zum Beispiel möglich, beim Stillstand oder Kriechgang der Greiferwebmaschine die Offenstellung mit grösserem Abstand vom Webfach vorzusehen und dieselbe während des Betriebes beispielsweise in Abhängigkeit von der Drehzahl näher an das Webfach heranzuführen und zwar derart, dass der Abstand auf das minimal Mögliche reduzierbar ist.The adjusting device of the present type is not used to switch the opener of the weft thread clamp ON or OFF, but remains in use both during the working stroke and during the idle stroke of the hook. In the case of the invention, the adjusting device is equipped with a control device with which the distance of the open position of the clamp from the shed or the selvedge can be adjusted during weaving. With the help of the control device, it is possible to adjust the distance of the open position of the clamp from the shed or the selvedge after the weft thread has been pulled through the shed to the respective operating conditions. For example, when the rapier weaving machine is at a standstill or crawling, it is possible to provide the open position at a greater distance from the shed and to bring it closer to the shed during operation, for example depending on the speed such that the distance can be reduced to the minimum possible.

Vorteilhafte Ausgestaltungen der Greiferwebmaschine sind in den Ansprüchen 2 bis 10 beschrieben.Advantageous embodiments of the rapier weaving machine are described in claims 2 to 10.

Eine besonders einfache Lösung der Stellvorrichtung beschreibt Anspruch 2. Aber auch eine Ausgestaltung nach Anspruch 3 ist möglich. Für den Regelantrieb der Stellvorrichtung Sind verschiedene Varianten denkbar, wie dies in den Ansprüchen 4 bis 8 angegeben ist.Claim 2 describes a particularly simple solution of the adjusting device. However, an embodiment according to Claim 3 is also possible. Various variants are conceivable for the control drive of the actuating device, as specified in claims 4 to 8.

Die Ansteuerung zum Regeln der Stellvorrichtung kann nun individuell von Hand geschehen oder automatisch, in dem die Stellvorrichtung beispielsweise gemäss Anspruch 8 ausgestaltet ist. Besonders vorteilhaft ist eine automatische Ansteuerung gemäss Anspruch 9.The control for regulating the actuating device can now be carried out individually by hand or automatically, in which the actuating device is designed, for example, according to claim 8. Automatic control according to claim 9 is particularly advantageous.

Die Stellvorrichtung ist sowohl für Greiferwebmaschinen mit einseitigen Greifern wie insbesondere gemäss Anspruch 10 für solche mit zweiseitigen Greifern geeignet.The adjusting device is suitable both for rapier weaving machines with one-sided rapiers and, in particular, for those with double-sided rapiers.

Die Figuren 1 bis 3 zeigen einen Nehmer-Greifer 2 einer Greiferwebmaschine mit zwei Schussfadeneintragvorrichtungen, d.h. zweiseitigen Greifern nach dem Verlassen des durch Kettfäden 4 gebildeten Webfaches 6, durch das der Nehmer-Greifer 2 einen Schussfaden 8 gezogen hat. Der Nehmer-Greifer 2 ist an einem Eintragband 10 befestigt und enthält an einem lanzenförmigen Teil 12 einen Aufnahmeschlitz 14 für den Schussfaden 8. Zur Verhinderung des ungewollten Herausgleitens des Schussfadens 8 ist eine Klemme 16 vorhanden, die um einen Bolzen 18 verschwenkbar ist und einen mit dem Aufnahmeschlitz 14 zusammenwirkenden Klemmarm 20 aufweist. Auf der dem Klemmarm 20 abgewandten Seite enthält sie einen weiteren Arm 22, der mittels einer Feder 24 in Klemmstellung vorgespannt ist. Der Klemmarm 22 bildet einen Auflaufnocken 26, der mit einem Oeffner, d.h. einer Stellvorrichtung 28 zum Oeffnen der Klemme zusammenwirkt.Figures 1 to 3 show a slave rapier 2 of a rapier weaving machine with two weft insertion devices, i.e. two-sided grippers after leaving the shed 6 formed by warp threads 4, through which the slave gripper 2 has drawn a weft thread 8. The slave gripper 2 is fastened to an infeed belt 10 and contains a receiving slot 14 for the weft thread 8 on a lance-shaped part 12. To prevent the weft thread 8 from sliding out unintentionally, a clamp 16 is provided which can be pivoted about a bolt 18 and with one the receiving slot 14 cooperating clamping arm 20. On the side facing away from the clamping arm 20, it contains a further arm 22 which is prestressed in the clamping position by means of a spring 24. The clamping arm 22 forms an overrun cam 26 which, with an opener, i.e. an actuator 28 cooperates to open the clamp.

Die Stellvorrichtung 28 enthält eine um einen Bolzen 30 schwenkbare Steuerleiste 32, die mit dem Auflaufnocken 26 zusammenwirkt. Die Neigung der Steuerleiste 32 und damit die Offenstellung der Klemme kann durch ein Exzenter-Getriebe 34 geregelt werden. Dabei kann der an einer Scheibe 36 angeordnete Exzenterzapfen 38 entweder von Hand betätigt werden oder mittels eines Elektromotors 40. Letzterer ist mit einer Steuervorrichtung 42 verbunden, die beispielsweise die Schalteinrichtung eines Hauptmotor und/oder eines Kriechgangmotors für die übrigen Aggregate der Greiferwebmaschine oder die mit einem Mikroprozessor ausgestattete Steuereinrichtung der Greiferwebmaschine sein kann.The adjusting device 28 contains a control bar 32 which can be pivoted about a bolt 30 and which cooperates with the overrun cam 26. The inclination of the control bar 32 and thus the open position of the terminal can be regulated by an eccentric gear 34. The eccentric pin 38 arranged on a disk 36 can either be operated by hand or by means of an electric motor 40 Microprocessor-equipped control device of the rapier weaving machine can be.

Diese Regelvorrichtung ermöglicht es, die Offenstellung frühzeitig zu bewirken, d.h. mit kurzem Abstand X1 vom Webfach bzw. von der Webkante 43, wenn die Steuerleiste gemäss Figur 2 praktisch parallel zur Laufrichtung des Nehmer-Greifers liegt. Bildet die Steuerleiste 32 hingegen eine Neigung zur Laufrichtung des Nehmer-Greifers, wie dies in Figur 3 gezeigt ist, so ergibt sich eine späte Offenstellung der Klemme 16 mit entsprechend grossem Abstand X2 vom Webfach 6 bzw. der Webkante.This control device makes it possible to effect the open position early, i.e. with a short distance X1 from the shed or from the selvedge 43, if the control bar according to FIG. 2 is practically parallel to the direction of travel of the slave rapier. If, on the other hand, the control bar 32 forms an inclination to the running direction of the slave gripper, as shown in FIG. 3, the clamp 16 is opened late with a correspondingly large distance X2 from the shed 6 or the selvedge.

Die Figur 4 zeigt ein weiteres Ausführungsbeispiel einer Stellvorrichtung 44, die eine mit dem Auflaufnocken 26 der Klemme 16 zusammenwirkende Steuerleiste 46 aufweist. Letztere enthält eine Auflaufkurve 48 und ist in Laufrichtung 50 des Nehmer-Greifers 2 verschiebbar. Hierzu ist die Steuerleiste 46 über Langlöcher 52 am Bolzen 54 gelagert. Zum Verschieben, d.h. Regeln dient ein fluidbetätigtes Kolben/Zylinder-Aggregat 56, dessen Kolbenstange 58 an einem Arm 60 der Steuerleiste 46 angelenkt ist. Die Ansteuerung d.h. Regelung der Stellvorrichtung 44 kann in mannigfacher, nicht näher dargestellter Weise analog den obigen Ausführungen erfolgen.FIG. 4 shows a further exemplary embodiment of an actuating device 44 which has a control bar 46 which interacts with the run-up cam 26 of the terminal 16. The latter contains a run-up curve 48 and is displaceable in the running direction 50 of the slave gripper 2. For this purpose, the control bar 46 is mounted on the bolt 54 via slots 52. To move, i.e. A fluid-operated piston / cylinder unit 56 is used to regulate, the piston rod 58 of which is articulated on an arm 60 of the control strip 46. The control i.e. Regulation of the adjusting device 44 can take place in a variety of ways, not shown in detail, analogous to the above statements.

Die Figur 5 zeigt ein weiteres Ausführungsbeispiel einer Stellvorrichtung 62, die ähnlich jener des Ausführungsbeispiels der Figuren 2 und 3 ausgebildet ist, wobei jedoch die Steuerleiste 32 mittels einer Feder 64 gegen den Nehmer-Greifer 2 bzw. dessen Klemme 16 vorgespannt ist, an der Steuerleiste 32 ist ein Zugorgan 66, z.B. eine Kordel, ein Riemen oder dergl. angeschlossen, das über eine Umlenkrolle 68 zu einer Steuervorrichtung 70 der Greiferwebmaschine geführt ist. Die Steuervorrichtung kann beispielsweise eine durch einen Mikroprozessor gesteuerte Fachbildevorrichtung, z.B. Jarquardvorrichtung sein, wobei eine Steuerlitze derselben mit dem Zugorgan 66 verbunden ist. Der Mikroprozessor kann dann die Steuerlitze und damit die Stellvorrichtung in Abhängigkeit von der Drehzahl der Grei ferwebmaschine steuern bzw. regeln.FIG. 5 shows a further exemplary embodiment of an actuating device 62, which is designed similarly to that of the exemplary embodiment of FIGS. 2 and 3, but the control strip 32 is prestressed against the slave gripper 2 or its clamp 16 on the control strip by means of a spring 64 32 is a tension member 66, for example a cord, a belt or the like. Connected, which is guided via a deflection roller 68 to a control device 70 of the rapier weaving machine. The control device can be, for example shedding device controlled by a microprocessor, for example a jar quard device, a control wire of which is connected to the traction element 66. The microprocessor can then control the control wire and thus the control device depending on the speed of the Grei ferwebmaschine.
