Abstract

Bei der Schaftantriebsvorrichtung ist der Antriebsteil (28) des Übertragungsmechanismus an die Querbalken (23) des Webschaftes (4) angekuppelt, so daß die Bewegungsrichtung (20) des Schaftes und die Antriebskraft für den Schaft (4) jeweils parallel zueinander verlaufen. Dadurch brauchen die Querstreben nicht besonders kräftig ausgebildet zu sein. Andererseits können die Längsbalken (21, 22) relativ leicht gebaut sein, weil auf sie keine Antriebskraft übertragen wird. Die Masse des gesamten Schaftes wird dadurch relativ gering, so daß sich die Antriebsvorrichtung besonders für hohe Drehzahlen der Webmaschine eignet.In the shaft drive device, the drive part (28) of the transmission mechanism is coupled to the crossbeams (23) of the heald frame (4), so that the direction of movement (20) of the shaft and the drive force for the shaft (4) each run parallel to one another. As a result, the cross struts do not need to be particularly strong. On the other hand, the longitudinal beams (21, 22) can be built relatively lightly because no driving force is transmitted to them. The mass of the entire shaft is relatively low, so that the drive device is particularly suitable for high speeds of the loom.

Description

Die Erfindung betrifft eine Schaftantriebsvorrichtung für eine Webmaschine, mit einem die Längs- und Querbalken enthaltenden Schäfte in Hin- und Herbewegung versetzenden Mechanismus zur Uebertragung der Antriebsbewegung.The invention relates to a shaft drive device for a weaving machine, with a mechanism for the transmission of the drive movement which causes the shafts containing the longitudinal and transverse beams to move back and forth.

Bei einer bisherigen Vorrichtung dieser Art (CH-PS 623 364 / T.497) besteht der Uebertragungsmechanismus aus einem Gestänge, das an dem unteren Längsbalken des Schaftes angreift. Das Gestänge enthält z.B. zwei auf und abwärts bewegte Steigplatinen, an deren oberen Enden jeweils ein Haken angebracht ist, welcher einen im unteren Längsbalken des Schaftes angebrachten, dazu passenden Stollen umgreift. Es liegt also eine formschlüssige Ankupplung des Uebertragungsmechanismus an den Schaft am unteren Längsbalken des Schaftes vor. Der Schaft muss zwecks Uebertragung der in den Längsbalken eingeleiteten Antriebskräfte mit besonders stark ausgebildeten Längsbalken versehen sein, wodurch eine entsprechend hohe Masse hin und her bewegt werden muss. Für hohe Drehzahlen der Webmaschine z.B. von 400 min-1 und mehr ist diese Antriebsart wegen der ständig zu beschleunigenden und wieder abzubremsenden Massen der Schäfte nicht geeignet.In a previous device of this type (CH-PS 623 364 / T.497), the transmission mechanism consists of a linkage which engages the lower longitudinal beam of the shaft. The linkage contains e.g. two climbing boards moved up and down, at the upper ends of which a hook is attached, which engages around a matching stud attached to the lower longitudinal beam of the shaft. So there is a positive coupling of the transmission mechanism to the shaft on the lower longitudinal beam of the shaft. For the transmission of the driving forces introduced into the longitudinal beams, the shaft must be provided with particularly strong longitudinal beams, as a result of which a correspondingly high mass has to be moved back and forth. For high speeds of the weaving machine e.g. This type of drive of 400 min-1 and more is not suitable due to the masses of the shafts that have to be continuously accelerated and braked again.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser hinsicht verbesserte Schaftantriebsvorrichtung zu schaffen.The invention has for its object to provide a shaft drive device which is particularly improved in this regard.

Die Erfindung besteht darin, dass der Uebertragungsmechanismus jeweils am Querbalken der Schäfte angekuppelt ist und Antriebsbewegung und Antriebskraft in den Querbalken des Schaftes eingeleitet ist.The invention consists in the fact that the transmission mechanism is coupled in each case to the crossbar of the shafts and drive motion and driving force are introduced into the crossbar of the shaft.

Durch die Einleitung von Antriebsbewegung und Antriebskraft in den Querbalken des Schaftes lässt sich erzielen, dass Antriebs- und Bremskraft des Uebertragungsmechanismus während des Betriebes ständig parallel zur Längserstreckung des Querbalkens liegen. Dadurch wird der die Antriebskraft aufnehmende Balken des Schaftes, nämlich der Querbalken, nicht auf Biegung beansprucht und kann relativ schwach ausgebildet sein. Demzufolge wird der ganze Schaft verhältnismässig leicht, weshalb sich die Vorrichtung besonders für hohe Drehzahlen z.B. bei Webmaschinen mit Lufteintrag eignet.By introducing the drive movement and driving force into the crossbeam of the shaft, it can be achieved that the driving and braking force of the transmission mechanism are constantly parallel to the longitudinal extension of the crossbeam during operation. As a result, the beam of the shaft, namely the crossbar, which absorbs the driving force is not subjected to bending and can be designed to be relatively weak. As a result, the entire shaft is relatively light, which is why the device is particularly suitable for high speeds, e.g. suitable for weaving machines with air intake.

Es lässt sich ferner erreichen, dass die Antriebskräfte seitens des Uebertragungsmechanismus z.B. unter Verwendung einer parallel zum Querbalken des Schaftes verlaufenden Verzahnung kraftschlüssig in den Querbalken eingeleitet werden. Gelenke zwischen Uebertragungsmechanismus und Schaftbalken lassen sich weitgehend vermeiden. Auch die Längsbalken des Schaftes können verhältnismässig leicht gebaut sein, so dass sie nur relativ geringen Massenanteil zur Gesamtmasse des Schaftes liefern.It can also be achieved that the drive forces on the part of the transmission mechanism e.g. using a toothing running parallel to the crossbeam of the shank can be introduced non-positively into the crossbeam. Joints between the transmission mechanism and the shaft beam can be largely avoided. The longitudinal beams of the shaft can also be built relatively lightly, so that they only provide a relatively small proportion of the total mass of the shaft.

Weitere Merkmale ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen in Verbindung mit der Zeichnung und den Ansprüchen.Further features result from the following description of exemplary embodiments in conjunction with the drawing and the claims.

  • Fig. 5 einen Schnitt nach Linie V - V in Fig. 2.5 shows a section along line V - V in FIG. 2.

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 weaving machine designated as a whole by 1, e.g. an air-entry machine, contains a machine frame 2, a shaft drive machine 3, e.g. Eccentric or card shaft 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 Gegenverzahnung 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 cross beams, of which in Fig. 1 only one is visible and designated 23. A rail-shaped extension element 24 is fastened to the crossbar 23, for example detached 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 pull cable 8 is connected with its two sections 8a, 8b at 38.39 to the link 28, e.g. jammed. On the rail-shaped member 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 Fig. 1,2 is on the opposite side, not shown, of the shaft is provided 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 much longer than the cross bars 23, so that 21, 22 form the longitudinal bars and 23 the cross bars. As a rule, crossbeams 23 are attached to the two ends of the longitudinal beams 21, 22; if the weaving width is large, 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.
