Description

Die Erfindung betrifft eine Antriebsvorrichtung für die Schäfte einer Webmaschine, bei der der Uebertragungsmechanismus für die Bewegung zu den Schäften an den parallel zu den Weblitzen verlaufenden Querbalken der Schäfte angelenkt ist.The invention relates to a drive device for the heald frames of a weaving machine, in which the transmission mechanism for the movement to the heald frames is articulated on the crossbeams of the heald frames running parallel to the healds.

Bei einer Vorrichtung gemäss der deutschen Patentschrift Nr. 857 629 besteht der Uebertragungsmechanismus aus einem Gestänge sowie Zugelementen, die an den Querbalken des Schaftes parallel zur Längserstreckung der Weblitzen angreifen. Die Teile des Gestänges sind an den Seiten des Webschaftes unten und oben an den Querbalken in Haken eingehängt. Zum Herausnehmen der Schäfte aus der Webmaschine müssen mindestens zwei Haken gelöst werden. Nach Entfernen eines oder mehrerer Schäfte ist der Mechanismus zur Hin- und Herbewegung der Schäfte unterbrochen. Die Teile des Gestänges müssen beim neuerlichen Ankuppeln von Schäften einzeln festgehalten und an entsprechende Teile des Webschaftes angehängt werden. Der Federrückzug, der den Uebertragungsmechanismus verspannt, ist zu entspannen, während die Schäfte aus der Webmaschine entfernt sind. Der Wechselvorgang für die Schäfte in einer Webmaschine mit der beschriebenen Schaftantriebsvorrichtung dauert entsprechend der Anzahl auszuführender Handgriffe relativ lange, wodurch der Betriebsnutzeffekt der Webmaschine sinkt.In a device according to German Patent No. 857 629, the transmission mechanism consists of a linkage and tension elements which act on the crossbar of the shaft parallel to the longitudinal extension of the healds. The parts of the boom are hooked onto the sides of the heald frame at the bottom and at the top of the crossbeams. To remove the shafts from the weaving machine, at least two hooks must be released. After one or more shafts have been removed, the mechanism for reciprocating the shafts is interrupted. The parts of the linkage must be individually held when coupling the heald and attached to the corresponding parts of the heald frame. The spring retraction, which tensions the transmission mechanism, must be relaxed while the shafts are removed from the weaving machine. The process of changing the heald frames in a weaving machine with the described shaft drive device takes a relatively long time, depending on the number of handles to be carried out, as a result of which the operating efficiency of the weaving machine is reduced.

Es ist Aufgabe der vorliegenden Erfindung, eine Schaftantriebsvorrichtung zu schaffen, deren Uebertragungsmechanismus zu den Schäften einfach handzuhaben ist. Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Schäfte an den Querbalken Ansatzelemente aufweisen, in welche eine in Richtung der Hin- und Herbewegung des Schaftes verlaufende Verzahnung eingearbeitet ist, an welche mittels eines Klemmelements eine ebenfalls mit einer Gegenverzahnung versehene Partie einer Lasche im Uebertragungsmechanismus angepresst wird. Nach Einbringen eines Schaftes in die Webmaschine muss zur Befestigung an den Uebertragungsmechanismus lediglich eine Verschraubung beispielsweise an einer Klemmhülse angezogen werden, wodurch der Schaft mit dem Uebertragungsmechanismus fest verbunden ist. Wenn die Rillen der Verzahnung in Längsrichtung des Querbalkens verlaufen, ist eine einfache Höhenverstellbarkeit des Schaftes gegeben. Die ineinandergreifenden Rillen am Ansatzelement des Schaftes und an der Lasche des Uebertragungsgestänges erzeugen eine hohe Flächenpressung zwischen den aneinandergedrückten Teilen und sorgen so für eine gute Sicherheit gegen Verrutschen des Schaftes gegenüber dem Uebertragungsmechanismus auch bei vergleichsweise bescheidener Verschraubungskraft. An der Lasche des Uebertragungsmechanismus kann eine Anschlagmuffe angeklemmt werden, welche dafür sorgt, dass nach Entfernung und Wiedereinlegen eines Schaftes in der Webmaschine ohne Umstände die ursprüngliche Schaftposition gefunden wird.It is an object of the present invention to provide a shaft drive device whose transmission mechanism to the shafts is easy to handle. The object is achieved according to the invention in that the shafts on the crossbeams have shoulder elements, into which a toothing running in the direction of the back and forth movement of the shaft is incorporated, to which a portion of a tab in the transmission mechanism, which is likewise provided with counter-toothing, is pressed by means of a clamping element becomes. After a shaft has been introduced into the weaving machine, only a screw connection, for example on a clamping sleeve, has to be tightened for fastening to the transmission mechanism, as a result of which the shaft is firmly connected to the transmission mechanism. If the grooves of the toothing run in the longitudinal direction of the crossbeam, the height of the shaft can be adjusted easily. The interlocking grooves on the attachment element of the shaft and on the tab of the transmission linkage create a high surface pressure between the pressed parts and thus ensure good security against slipping of the shaft against the transmission mechanism even with a comparatively modest screwing force. Connections a can by the tab of the transmission mechanism h lagmuffe be clamped, which ensures that the original stem position is found, after removal and re-insertion of a shaft in the weaving machine without any fuss.

Die als Ganzes mit 1 bezeichnete Webmaschine, z. B. eine Lufteintragsmaschine, enthält ein Maschinengestell 2, eine Schaftantriebsmaschine 3, z. B. Exzenter- oder Kartenschaftmaschine, und mehrere Schäfte, von denen in Fig. 1 nur einer gezeichnet und mit 4 bezeichnet ist.The loom designated as a whole with 1, for. B. an air entry machine, contains a machine frame 2, a shaft drive machine 3, z. B. eccentric or card stock machine, and several shafts, of which only one is shown in Fig. 1 and designated 4.

Die Schaftmaschine 3 enthält für jeden Schaft einen bei 5 schwenkbar gelagerten Antriebshebel 6, eine daran angelenkte Zugklemme 7, an welcher ein aus zwei Abschnitten 8a, 8b bestehendes Zugseil 8 angeklemmt ist. Dieses ist über eine ortsfeste Rolle 9 zu einer Stelle 11 geführt, an welcher es an den Schaft 4 angekuppelt ist. In Fig. 1 oben ist das Zugseil 8 über eine bei 12 schwenkbar gelagerte Bogenschwinge 13 geleitet, an der es auch befestigt ist. Ein Federzug 14 greift bei 15 an die Bogenschwinge 13 an und ist bestrebt, diese in Fig. 1 in Uhrzeigersinn zu verschwenken. Während des Webbetriebes wird der Schaft 4 in Fig. 1 unter der abwärtsziehenden Zugkraft des Eilabschnittes 8a nach unten bewegt ; unter der aufwärtsziehenden, vom Federzug 14 erzeugten Kraft des Seilabschnittes 8b wird der Schaft aufwärtsbewegt.The dobby 3 contains for each shaft a drive lever 6 pivotably mounted at 5, a pull clamp 7 articulated thereon, to which a pull rope 8 consisting of two sections 8a, 8b is clamped. This is guided via a fixed roller 9 to a point 11 at which it is coupled to the shaft 4. In Fig. 1 above, the pull cable 8 is guided over a swing arm 13 pivotally mounted at 12, to which it is also attached. A spring balancer 14 engages the bow rocker 13 at 15 and strives to pivot it clockwise in FIG. 1. During weaving operation, the shaft 4 in FIG. 1 is moved downward under the pulling force of the rapid section 8a; the shaft is moved upwards under the upward force of the cable section 8b generated by the spring balancer 14.

Der Schaft 4 enthält zwei Längsbalken 21, 22, die durch Querbalken miteinander verbunden sind, von denen in Fig. 1 nur einer sichtbar und mit 23 bezeichnet ist. An dem Querbalken 23 ist ein schienenförmiges Ansatzelement 24 befestigt, z. B. bei 25 angelöstet. Das Ansatzelement 24 besitzt auf der in fig. 2 rechten Seite eine parallel zur Bewegungsrichtung 20 verlaufende Verzahnung 26, In welche eine in gleicher Richtung verlaufende Gegenverzhnung 27 eines ebenfalls schienenförmig ausgebildeten Gliedes 28 des Seilzuges 8 eingreift. Das Glied 28 besitzt an der der Verzahnung 27 gegenüberliegenden Seite eine wiederum parallel zu Pfeil 20 verlaufende Verzahnung 31, in welche eine Gegenverzahnung 32 einer Klemmhülse 33 eingreift. Die Teile 31, 32 bilden eine Zusatzverzahnung.The shaft 4 contains two longitudinal beams 21, 22 which are connected to one another by transverse beams, of which only one is visible in FIG. 1 and is designated by 23. On the crossbar 23, a rail-shaped extension element 24 is attached, for. B. solved at 25. The attachment element 24 has on the in Fig. 2 on the right-hand side a toothing 26 running parallel to the direction of movement 20, in which a counter toothing 27 running in the same direction engages a link 28 of the cable pull 8 which is also of rail-shaped design. The link 28 has, on the side opposite the toothing 27, a toothing 31, again running parallel to the arrow 20, into which a counter toothing 32 of a clamping sleeve 33 engages. The parts 31, 32 form an additional toothing.

Die Klemmhülse 33 umschliesst die Teile 24, 28. welche mittels einer Schraube 35 unter Zwischenlage eines U-förmigen Druckstückes 36 zusammengeklemmt sind.The clamping sleeve 33 encloses the parts 24, 28 which are clamped together by means of a screw 35 with the interposition of a U-shaped pressure piece 36.

Das Zugseil 8 ist mit seinen beiden Abschnitten 8a, 8b bei 38, 39 mit dem Glied 28 verbunden. z. B. verklemmt. Auf dem schienenförmigen Glied 28 ist eine Anschlagmuffe 41 verschiebbar und mittels einer Schraube 42 höheneinstellbar angebracht. Durch die Verzahnungen 26, 27, 31, 32 wird die seitens des Zugseiles 8 auf die Kupplungsstelle 11 geleitete Antriebs- bzw. Bremskraft jeweils in Richtung 20 der Bewegung des Schaftes 4 eingeleitet ; es liegt eine kraftschlüssige Bewegungsübertragung vor. Der Schaft 4 lässt sich stufenlos entlang der Verzahnung 27 an das schienenförmige Glied 28 des Seilzuges 8 ankuppeln, welcher den seitens des Uebertragungsmechanismus 6, 8, 13 hin und her bewegten Antriebsteil für den Schaft 4 bildet.The traction cable 8 is connected with its two sections 8a, 8b at 38, 39 to the link 28. e.g. B. jammed. On the rail-shaped Link 28, a stop sleeve 41 is slidable and height-adjustable by means of a screw 42. Through the toothing 26, 27, 31, 32, the drive or braking force directed by the pull cable 8 to the coupling point 11 is introduced in each case in the direction 20 of the movement of the shaft 4; there is a non-positive transmission of motion. The shaft 4 can be coupled continuously along the toothing 27 to the rail-shaped member 28 of the cable 8, which forms the drive part for the shaft 4 which is moved back and forth by the transmission mechanism 6, 8, 13.

Die in Fig. 1, 2 dargestellte Kupplungspartie 11 ist auf der gegenüberliegenden, nicht dargestellten Seite des Schaftes in entsprechender Weise vorgesehen, so dass der Schaft 4 an den beiden Querbalken 23 angetrieben wird. Die nicht sichtbare, linke Kupplungspartie 11 wird über ein Seil 8c ebenfalls von der Schaftmaschine 3 angetrieben.The coupling section 11 shown in FIGS. 1, 2 is provided on the opposite side, not shown, of the shaft in a corresponding manner, so that the shaft 4 is driven on the two crossbeams 23. The invisible, left coupling part 11 is also driven by the dobby 3 via a cable 8c.

Bei einer abgewandelten Ausführungsform besteht das Ansatzelement 24 mit dem Querbalken 23 aus einem Stück. Die Bewegungsrichtung des Schaftes 4 verläuft bei den meisten Webmaschinen auf und abwärts. Die Balken 22 sind in der Regel wesentlich länger ausgebildet als die Querbalken 23, so dass 21, 22 die Längsbalken und 23 die Querbalken bilden. In der Regel sind an den beiden Enden der Längsbalken 21, 22 Querbalken 23 angebracht, bei grosser Webbreite können auch dazwischen Querbalken 23 (Zwischenstreben) vorgesehen sein. Erfindungsgemäss greift der Uebertragungsmechanismus 6, 8, 28 an denjenigen Balken der Schäfte 4 an, welche parallel zur Bewegungsrichtung 20 verlaufen.In a modified embodiment, the extension element 24 with the crossbar 23 consists of one piece. The direction of movement of the shaft 4 runs up and down in most weaving machines. The bars 22 are generally made much longer than the crossbars 23, so that 21, 22 form the longitudinal bars and 23 the crossbars. As a rule, crossbeams 23 are attached to the two ends of the longitudinal beams 21, 22; with a large weaving width, crossbeams 23 (intermediate struts) can also be provided between them. According to the invention, the transmission mechanism 6, 8, 28 engages those beams of the shafts 4 which run parallel to the direction of movement 20.
