Description

Die Erfindung betrifft eine Kupplungsanordnung zum Steuern der Schäfte einer Webmaschine, mit einer mindestens eine Nut aufweisenden, intermittierend drehenden Antriebswelle und einer in die Nut einkuppelbaren, auf einem auf der Antriebswelle drehbar gelagerten Exzenter angeordneten Klinke und mit mindestens einem in den Weg der Klinke bewegbaren, sie auskuppelnden Steuerhebel, welcher von einem Hubmessertrieb aus verschwenkbar und von einer Feder gegen einen ortsfesten Anschlag gezogen ist.The invention relates to a coupling arrangement for controlling the shafts of a weaving machine, with an intermittently rotating drive shaft having at least one groove and an engaging pawl which can be coupled into the groove and is arranged on a cam rotatably mounted on the drive shaft and with at least one pawl which can be moved in the path of the pawl. they disengage the control lever, which can be pivoted from a lifting knife drive and is pulled by a spring against a stationary stop.

Bei einer bisherigen Kupplungsanordnung (DE-PS 11 54 048) werden die Steuerhebel über von einem Hubmessertrieb aus in Bewegung gesetzte Züge in Wirkungsstellung gebracht, in der die Klinke ausgekuppelt werden kann. Soll die Rückführung der Steuerhebel in wirkungslose Stellung unter dem Einfluss einer Feder erfolgen, durch welche die Steuerhebel gegen einen Anschlag gedrückt werden, so hat die Feder bei Anschlagstellung der Steuerhebel die geringste Auslenkung und damit die geringste Spannung. Der zugehörige Steuerhebel neigt daher beim Auflaufen auf den Anschlag zu Schwingungen, so dass er nicht sofort zur Ruhe kommt und auch nicht mit genügender Kraft in Ruhestellung gehalten wird.In a previous clutch arrangement (DE-PS 11 54 048), the control levers are brought into operative position via trains set in motion by a lifting knife drive, in which the pawl can be disengaged. If the control levers are to be returned to an ineffective position under the influence of a spring, by means of which the control levers are pressed against a stop, the spring has the least deflection and thus the lowest tension when the control levers are in the stop position. The associated control lever therefore tends to vibrate when it hits the stop, so that it does not come to rest immediately and is not held in the rest position with sufficient force.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Hinsicht verbesserte Anordnung zu schaffen.The invention has for its object to provide a particularly improved arrangement in this regard.

Diese Aufgabe wird durch die Kupplungsanordnung gemäß Anspruch 1 gelöst. Durch die erfindungsgemäße Anordnung lässt sich erreichen, dass der Steuerhebel während des Auflaufens auf den ortsfesten Anschlag unter besonders starker Federkraft steht. Die Kraft der Rückziehfeder, die in dieser Position relativ schwach ist, kann ergänzt werden durch die Kraft der Zusatzfeder. Schwingungen beim Aufschlagen des Steuerhebels lassen sich dadurch vermeiden bzw. dämpfen. Auch kann der Steuerhebel während des Betriebes nicht etwa infolge von Maschinenschwingungen aus der Wirkungsstellung bewegt werden. Das dieser Stellung entsprechende Auskuppeln der Klinke der Kupplungsanordnung kann daher besonders zuverlässig durchgeführt werden.This object is achieved by the coupling arrangement according to claim 1. The arrangement according to the invention makes it possible for the control lever to be under particularly strong spring force when it hits the stationary stop. The force of the return spring, which is relatively weak in this position, can be supplemented by the force of the additional spring. This prevents or dampens vibrations when the control lever is knocked open. Also, the control lever cannot be moved from the operative position due to machine vibrations during operation. The disengagement of the pawl of the clutch arrangement corresponding to this position can therefore be carried out particularly reliably.

Weitere Merkmale ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen in Verbindung mit der Zeichnung und den Ansprüchen.

  • Figur 1 ist ein Schnitt durch eine erfindungsgemäss ausgebildete Kupplungsanordnung zur Steuerung von Webschäften einer Webmaschine und
  • Figur 2 erläutert eine andere Position der Teile.
Further features result from the following description of exemplary embodiments in conjunction with the drawing and the claims.
  • FIG. 1 is a section through a coupling arrangement designed according to the invention for controlling heald frames of a weaving machine and
  • Figure 2 illustrates another position of the parts.

Eine von der Hauptwelle der Webmaschine aus absatzweise jeweils um 180° in Drehung versetzte Antriebswelle 1 enthält zwei Nuten 2, in welche die Nase 3 einer bei 4 schwenkbar gelagerten, unter Wirkung einer Zugfeder 60 stehenden Kupplungsklinke 5 eingreifen kann. Die Klinke 5 ist auf einem auf Welle 1 drehbar gelagerten Exzenter 6 gelagert, der von einer Lasche 7 umschlossen ist. Diese ist bei 8 an einem Uebertragungsgestänge 9 angelenkt, über welches die gemäss Pfeil 11 entstehende Hin- und Herbewegung der Lasche 7 auf einen zugehörigen Schaft einer Webmaschine übertragen wird. Auf Welle 1 sind eine ganze Anzahl, z. B. sechs bis zwölf der in Fig. 1 dargestellten Antriebsteile 6, 7 angeordnet, nämlich zu jedem Schaft der Webmaschine ein Exzenter 6 und eine Lasche 7. Die gesamten Teile 1, 6, 7 bilden die sogenannte Exzentermaschine für Antrieb und Steuerung sämtlicher Webschäfte der Webmaschine. Die Schäfte werden entsprechend einem Bindungsprogramm für die Kettfäden in Hoch- oder Tieffachstellung bewegt.A drive shaft 1, which is set in rotation by 180 ° from the main shaft of the weaving machine in each case, contains two grooves 2, into which the nose 3 of a coupling pawl 5 pivotably mounted at 4 and acting under the action of a tension spring 60 can engage. The pawl 5 is mounted on an eccentric 6 rotatably mounted on shaft 1, which is enclosed by a tab 7. This is articulated at 8 to a transmission linkage 9, via which the back and forth movement of the tab 7, which arises in accordance with arrow 11, is transmitted to an associated shaft of a weaving machine. On wave 1 there are a whole number, e.g. B. six to twelve of the drive parts 6, 7 shown in Fig. 1, namely an eccentric 6 and a tab 7 for each shaft of the loom. The entire parts 1, 6, 7 form the so-called eccentric machine for driving and controlling all heald frames Weaving machine. The shafts are moved in a high or low position according to a binding program for the warp threads.

Zur Betätigung der Klinke 5 während des Betriebes sind zwei auf den ortsfesten Lagerzapfen 12, 13 schwenkbar gelagerte Steuerhebel 14, 15 bzw. 16, 17 eingebaut, die an den freien Enden Haken 18 aufweisen, welche in den Weg der Klinke 5 verschwenkt werden können. Die beiden Steuerhebel sind mit den Armen 15,17 bei 21 durch ein Gelenk verbunden.To actuate the pawl 5 during operation, two control levers 14, 15 and 16, 17 pivotally mounted on the fixed bearing journals 12, 13 are installed, which have hooks 18 at the free ends, which can be pivoted into the path of the pawl 5. The two control levers are connected to the arms 15, 17 at 21 by a joint.

Auf dem Arm 15 ist bei 22 eine Platine 23 schwenkbar gelagert, die mit einem gemäss Pfeil 24 hin- und herbewegten Hubmesser 25 gekuppelt werden kann.On the arm 15 a plate 23 is pivotally mounted at 22, which can be coupled with a reciprocating knife 25 moved back and forth according to arrow 24.

Das Hubmesser 25 ist auf einem um 26 hin und her verschwenkbaren, zweiarmigen Antriebshebel 27, 28 befestigt. Der Arm 28 enthält einen Schlitz 31, in dem eine unter Wirkung einer Zugfeder 32 stehende, sich über die ganze Länge von Antriebswelle 1 erstreckende und damit sämtliche nebeneinander angeordnete Steuerhebel 16, 17 erfassende Walze 30 verschiebbar angeordnet ist. Die Feder 32 ist an dem anderen Ende bei 33 auf dem Arm 28 befestigt.The lifting knife 25 is fastened on a two-armed drive lever 27, 28 which can be pivoted back and forth by 26. The arm 28 contains a slot 31 in which a roller 30, which acts under the action of a tension spring 32 and extends over the entire length of the drive shaft 1 and thus detects all control levers 16, 17 arranged next to one another, is displaceably arranged. The spring 32 is attached to the arm 28 at 33 at the other end.

Die Wirkungsweise ist folgende. Bei der Kupplungsstellung der Klinke 5 nach Fig. 1 wird die Drehbewegung der Welle 1 gemäss Pfeil 66 über die Klinke 5 auf den Exzenter 6 übertragen, so dass die Schwinge 7 und das Gestänge 9 gemäss Pfeil 11 hin und her bewegt werden und der zugehörige Webschaft wechselweise von der Hochfachstellung in die Tieffachstellung und zurück bewegt wird. Die Platine 23 steht dabei in Eingriff mit dem Hubmesser 25, durch welches sei jeweils bei der Bewegung des Hubmessers in Fig. 1 nach rechts gegen die Wirkung der Feder 55 ebenfalls nach rechts bewegt wird. Hierdurch gelangen die beiden Steuerhebel 14 bis 17 in die in Fig. 1 gezeichnete, wirkungslose Position, in der das Ende 61 der Klinke 5 unter den beiden Haken 18 der Steuerhebel 14 bis 17 hindurchzulaufen vermag, ohne von ihnen ergriffen zu werden.The mode of action is as follows. In the coupling position of the pawl 5 according to FIG. 1, the rotary movement of the shaft 1 according to arrow 66 is transmitted via the pawl 5 to the eccentric 6, so that the rocker 7 and the linkage 9 are moved back and forth according to arrow 11 and the associated heald frame is alternately moved from the high position to the low position and back. The circuit board 23 is in engagement with the lifting knife 25, by means of which the movement of the lifting knife in FIG. 1 also moves to the right against the action of the spring 55 to the right. As a result, the two control levers 14 to 17 move into the ineffective position shown in FIG. 1, in which the end 61 of the pawl 5 can pass under the two hooks 18 of the control levers 14 to 17 without being gripped by them.

Bei Bewegung des Hubmessers 25 in Fig. 1 nach links folgen Platine 23 sowie die Arme 15, 17 der Steuerhebel nach links unter der Wirkung der Zugfeder 55, so dass die Steuerhebel vorübergehend in Wirkungsstellung gelangen. Das Ende 61 der Klinke 5 befindet sich jedoch zu diesem Zeitpunkt nicht im Bereich eines der Haken 18. Bei der folgenden Rechtsbewegung des Hubmessers 25 werden die Teile wieder in die Position nach Fig. 1 bewegt. Die Walze 30 verbleibt bei allen diesen Bewegungen in der Sohle 41 des Schlitzes 31.When the lifting knife 25 moves to the left in FIG. 1, the board 23 and the arms 15, 17 of the control lever follow to the left under the effect of Tension spring 55 so that the control levers temporarily move into the operative position. At this time, however, the end 61 of the pawl 5 is not in the area of one of the hooks 18. When the lifting knife 25 moves to the right, the parts are moved back into the position according to FIG. 1. The roller 30 remains in the sole 41 of the slot 31 during all these movements.

Zwecks Stillsetzung des Webschaftes in der Hochfach- oder in der Tieffachstellung wird von einer nicht dargestellten Programmsteuereinrichtung Klinke 23 am Ende eines Linkshubes des Hubmessers 25 aus der Kupplungsstellung in Fig. 1 in die wirkungslose, obere Postion 23a (Fig. 2) gehoben, in der sie ausser Eingriff mit dem Hubmesser 25 steht. Kurz bevor der Arm 17 auf den Anschlag 54 aufläuft, legt sich die Walze 30 gegen den Arm 16. Bei der weiteren Bewegung des Hebels 27, 28 gemäss Pfeil 40 läuft auch der Arm 28 im Gegenzeigersinn weiter, so dass sich die Walze 30 von der Sohle 41 des Schlitzes 31 unter gleichzeitiger, zusätzlicher Anspannung der Zugfeder 32 abhebt. Es entsteht die Position nach Fig. 2.For the purpose of stopping the heald frame in the high shed or in the shed position, a program control device, not shown, pawl 23 at the end of a left stroke of the lifting knife 25 lifts it from the coupling position in FIG. 1 into the ineffective, upper position 23a (FIG. 2), in which it is out of engagement with the lifting knife 25. Shortly before the arm 17 runs onto the stop 54, the roller 30 lies against the arm 16. When the lever 27, 28 moves further according to arrow 40, the arm 28 also continues to run in the counterclockwise direction, so that the roller 30 moves away from the Sole 41 of the slot 31 lifts up while simultaneously tensioning the tension spring 32. The position according to FIG. 2 is created.

Während also beim Auflaufen des Armes 17 auf den Anschlag 54 die Feder 55 geringere Spannkraft erhält, nimmt die Zugspannung der Feder 32 entsprechend zu, so dass der Steuerhebel 16, 17 gleichwohl unter genügender Spannung auf den Anschlag 54 auftrifft und Schwingungen beim Aufschlagen oder während des folgenden Betriebes seitens der Maschine weitgehend unschädlich gemacht sind. Der Arm 17 bleibt unter der ausreichenden Spannkraft der Federn 55 und insbesondere 32 ausreichend fest auf dem Anschlag 54 gehalten. Walze 30 hat somit dämpfende Wirkung gegenüber dem Aufschlagen oder den Maschinenschwingungen. In der Position nach Fig. 2 läuft das Ende 61 der Klinke 5 auf einen der Haken 18 der Steuerhebel 14 bis 17 auf, so dass die in Fig. 2 dargestellte Auskupplungsstellung von Klinke 5 entsteht, wonach der Exzenter 6, die Schwinge 7, das Gestänge 9 und der zugehörige Webschaft in Ruhestellung gelangen.So while the arm 55 hits the stop 54 the spring 55 receives less tension, the tension of the spring 32 increases accordingly, so that the control lever 16, 17 hits the stop 54 with sufficient tension and vibrations when struck or during following operation on the part of the machine are largely made harmless. The arm 17 remains held sufficiently firmly on the stop 54 under the sufficient tensioning force of the springs 55 and in particular 32. Roller 30 thus has a damping effect against impact or machine vibrations. In the position shown in FIG. 2, the end 61 of the pawl 5 runs onto one of the hooks 18 of the control levers 14 to 17, so that the disengaged position of the pawl 5 shown in FIG. 2 arises, after which the eccentric 6, the rocker 7, the Linkage 9 and the associated heald frame come to rest.
