Abstract

The coupling arrangement contains a stop (83) which is driven by means of a lever (86, 87) and behind which the hook-shaped free end (82) of the sinker (23) can engage with play A when the sinker (23) is to be moved into the upper position according to the particular program. This ensures that, during the upward movement of the sinker (23), the hook (82) can reliably engage behind the stop (83) and, for example, the surface (96) of the hook (82) cannot strike against the surface (97) of the stop (83) as a result of machine vibrations. When the sinker (23) is moved upwards, the stop (83) is moved to the left again by the lever (86, 87) and the play A is cancelled. The sinker (23) and the control levers (14-17) are thereby locked. The hooks (18) cannot momentarily be pivoted upwards as a result of machine vibrations or by being taken up by the pawl (5), the result of which would be that the pawl (5) could be coupled to the shaft (1) in an undesirable way. Operating faults in the movements of the heald frame of the weaving machine are thereby prevented. <IMAGE>

Description

Die Erfindung bezieht sich auf 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 sowie mit einer den Exzenter umschliesssenden Lasche einer Kurbelstange für den Anhieb zu den Schäften und mindestens einem in den Weg der Klinke bewegbaren, sie auskuppelnden Steuerhebel, welcher von einer in einen Hubmessertrieb einkuppelbaren Platine hin- und her verschwenkbar 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 a pawl which can be coupled into the groove and is arranged on an eccentric rotatably mounted on the drive shaft, and with a tab of a crank rod which encloses the eccentric for the stroke to the shafts and at least one control lever which can be moved in the path of the pawl and disengages them and which can be pivoted back and forth by a circuit board which can be coupled into a lifting knife drive.

bereits Bei einer/vorgeschlagenen Anordnung dieser Art (EP-Anmeldung 80105440.4) ist der Anschlag für die Platine ortsfest angeordnet. Die Kooperation zwischen Platine und Anschlag kann bei dieser bekannten Ausführungsform unsicher werden. Bei Schwingungen während des Betriebes kann es z. B. vorkommen, dass die Platine bei Beginn des Verriegelungsvorganges, wo sie gegen den ortsfesten Anschlag hin bewegt wird, in unerwünschter Weise mit ihrem Ansatz gegen den Anschlag trifft und gegebenenfalls in den Hubmessertrieb zurück geworfen werden kann. Die Verriegelung wird dadurch verspätet eingeleitet oder unmöglich gemacht. Der Betrieb wird gestört.Already in a / proposed arrangement of this type (EP application 80105440.4), the stop for the circuit board is arranged in a stationary manner. The cooperation between the circuit board and the stop can become uncertain in this known embodiment. In the event of vibrations during operation, it can e.g. B. occur that the board at the beginning of the locking process, where it is moved against the stationary stop, hits in an undesirable manner with its approach against the stop and possibly thrown back into the linear drive can be. This means that the locking is initiated late or made impossible. Operation is disrupted.

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

Die Erfindung besteht darin, dass die Platine unter Zwischenschaltung einer Feder von einem Hubteil angetrieben ist, der zugleich als federndes Abtastelement zum Abtasten einer zugehörigen Programmsteuereinrichtung ausgebildet ist. Hierdurch wird es möglich, beim Aufschlagen der Platine auf den Anschlag ein genügend grosses Spiel zwischen Anschlag und Platinenansatz vorzusehen, sodass dieser Vorgang auch unter Berücksichtigung von Maschinenschwingungen sicher vonstatten gehen kann. Nachdem die Platine ihre Anschlagsstellung erreicht hat, kann der Anschlag durch den Antrieb in eine zweite Position überführt werden, in welcher das Spiel ganz oder weitgehend aufgehoben ist und der Platinenansatz hinter den Anschlag greift. In dieser Position wird vermieden, dass die in Wirkungsstellung befindlichen Steuerhebel etwa durch Schwingungen während des Betriebes momentan in wirkungslose Stellung überführt werden. Vielmehr werden die Steuerhebel durch die verriegelte Platine zwangläufig in ihrer Wirkungsstellung gehalten. Die Klinke bleibt dann so lange mit Sicherheit ausgekuppelt, wie es dem Programm entspricht. Die Schäfte der Webmaschine laufen daher exakt programmgemäss.The invention consists in that the circuit board is driven, with the interposition of a spring, by a lifting part which is at the same time designed as a resilient scanning element for scanning an associated program control device. This makes it possible to provide sufficient clearance between the stop and the base of the board when the board is struck on the stop, so that this process can also take place safely, taking machine vibrations into account. After the board has reached its stop position, the drive can move the stop into a second position, in which the play is completely or largely eliminated and the board attachment engages behind the stop. In this position it is avoided that the control levers in the operative position are momentarily brought into an ineffective position by vibrations during operation. Rather, the control levers are inevitably held in their operative position by the locked circuit board. The jack will then remain safely disengaged as long as the program corresponds. The weaving machine shafts therefore run exactly according to the program.

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. 1 ist ein Schnit durch eine erfindungsgemäss ausgebildete Kupplungsanordnung zur Steuerung von Webschäften einer Webmaschine,1 is a section through a coupling arrangement designed according to the invention for controlling heald frames of a weaving machine,
  • Fig. 2 veranschaulicht ein Detail aus Fig. 1 in grösserem Massstab.FIG. 2 illustrates a detail from FIG. 1 on a larger scale.

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.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.

Auf Welle 1 sind eine ganze Anzahl, z. B. sechs bis vierzehn 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- und Tieffachstellung bewegt.On wave 1 there are a whole number, e.g. B. six to fourteen of the drive parts 6, 7 shown in Fig. 1, namely an eccentric 6 for each shaft of the loom, and a tab 7. The entire parts 1, 6, 7 form the so-called eccentric machine for driving and controlling all heald frames the weaving machine. The shafts are moved according to a binding program for the warp threads in the up and down positions.

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 Web 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 pins 12, 13 are installed, which have hooks 18 at the free ends, which can be pivoted into the web 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 geäss Pfeil 24 hin- und her bewegten 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.

Die Platine 23 besitzt einen gabelförmigen Teil 26, der einen Schlitz 27 bildet. In diesen greift ein Zapfen 28 eines nicht dargestellten Antriebshebels ein, wodurch die Platine 23 während des Betriebes entsprechend Pfeil 81 um 22 hin und her verschwenkt werden kann. In der in Fig. 2 dargestellten, oberen Position ist Platine 23 vom Hubmesser 25 ausgekuppelt, in der gestrichelt angedeuteten, unteren Position 26a kooperiert die Platine mit dem Hubmesser 25. Sie wird von diesem hin- oder herbewegt, so dass die Hebel 14 - 17 um ihre Lagerzapfen 12, 13 verschwenkt werden.The board 23 has a fork-shaped part 26 which forms a slot 27. A pin 28 of a drive lever, not shown, engages in this, whereby the board 23 can be pivoted back and forth by 22 according to arrow 81 during operation. In the upper position shown in FIG. 2, the board 23 is disengaged from the lifting knife 25, in the lower position 26a, indicated by dashed lines, the board cooperates with the lifting knife 25. It is moved back and forth by the latter, so that the levers 14-17 to be pivoted about their journals 12, 13.

Das in Fig. 1 linke, freie Ende 82 der Platine 23 ist hakenförmig ausgebildet, so dass es bei der in Fig. 2 ausgezogen dargestellten, oberen Position hinter einen Anschlag 83 zu greifen vermag, vgl. Fig. 2. Anschlag 83 ist mittels einer Schraube 84 an einem um 85 verschwenkbaren, zweiarmigen Hebel 86, 87 befestigt. Anschlag 83 erstreckt sich in Fig. 2 senkrecht zur Zeichenebene über sämtliche zu den Schäften gehördenden Antriebsteile 14 - 17, 23 und ist an seinem anderen, dem Beschauer abgewandten Ende an einem weiteren, dem Hebel 86, 87 entsprechenden Hebel befestigt.The free end 82 of the board 23 on the left in FIG. 1 is hook-shaped, so that it can reach behind a stop 83 in the upper position shown in FIG. 2, see FIG. Fig. 2. Stop 83 is fastened by means of a screw 84 to a two-armed lever 86, 87 which can be pivoted by 85. Stop 83 in FIG. 2 extends perpendicular to the plane of the drawing over all drive parts 14 - 17, 23 belonging to the shafts and is attached at its other end facing away from the viewer to a further lever corresponding to lever 86, 87.

In das gabelförmige, freie Ende 88 des Armes 87 greift ein Bolzen 89 ein, der auf einem Arm 91 eines dreiarmigen, um 94 schwenkbaren Hebels 91, 92, 93 sitzt. Der Hebel 91 - 93 wird während des Betriebes entsprechend Pfeil 95 hin und her bewegt, so dass der Bolzen 89 in dem Schlitz des Endes 88 hin- und her bewegt wird und dabei den Hebel 86, 87 um 85 hin- und her verschwenkt.A bolt 89 engages in the fork-shaped, free end 88 of the arm 87 and sits on an arm 91 of a three-armed lever 91, 92, 93 which can be pivoted about 94. The lever 91-93 is moved back and forth during operation in accordance with arrow 95, so that the bolt 89 is moved back and forth in the slot of the end 88 and thereby pivots the lever 86, 87 back and forth by 85.

Die Wirkungsweise ist folgende. Das Hubmesser 25 und der Anschlag 83 werden während des Betriebes dauernd gegenläufig angetrieben, d. h. wenn das Hubmesser 25 nach links bewegt wird, wird der Anschlag 83 nach rechts bewegt und umgekehrt. Auf eine Drehung von 180 der Welle 1 kommt jeweils eine volle Hin- und Herbewegung von Hubmesser 25 und Anschlag 83.The mode of action is as follows. The lifting knife 25 and the stop 83 are continuously driven in opposite directions during operation, ie when the lifting knife 25 moves to the left the stop 83 is moved to the right and vice versa. For a rotation of 180 of the shaft 1 there is a full reciprocating movement of the lifting knife 25 and stop 83.

Wenn programmgemäss die Platine 23 aus der unteren,in Fig. 2 strichpunktiert angedeuteten Position in die obere, ausgezogen dargestellte Stellung bewegt werden soll, steht der Anschlag 83 in der gestrichelt angedeuteten, rechten Stellung. Nunmehr wird Platine 23 und damit das hakenförmige Ende 82 nach oben bewegt. Das Ende 82 hintergreift den Anschlag 83 unter relativ grossem Spiel A.If, according to the program, the board 23 is to be moved from the lower position shown in broken lines in FIG. 2 to the upper position shown in solid lines, the stop 83 is in the right-hand position shown in broken lines. Now the board 23 and thus the hook-shaped end 82 is moved upwards. The end 82 engages behind the stop 83 with a relatively large clearance A.

Anschliessend wird zusammen mit der Rechtsbewegung des Hubmessers 25 der Hebel 91 - 93 im Uhrzeigersinn und der Hebel 86, 87 im Gegenzeigersinn verschwenkt. Damit wird der Anschlag 83 nach links bewegt, so dass das Spiel A aufgehoben wird. Die Platine 23 befindet sich nunmehr in der Fig. 1 ausgezogen gezeichneten, linken, oberen Position, in welcher die Steuerhebel 14 - 17 in der dargestellten Wirkungsstellung sind. Die Haken 18 ragen in den Weg des freien Endes 61 der mit der Welle 1 rotierenden, eingekuppelten Klinke 5, wodurch das Ende 61 auf einen der Haken 18 aufläuft. Bei weiterer Drehung entsprechend Pfeil 66 wird-Klinke 5 aus der Welle 1 ausgekuppelt und gelangt in die in Fig. 1 gestrichelt dargestellte Position 5a. Der Arm 17 ist in Anlage an dem ortsfesten Anschlag 54, auf dem er unter Wirkung der Zugfeder 55 gehalten wird. Da die Teile 23, 14 - 17 verriegelt sind, wird verhindert, dass beispielsweise infolge von Maschinenschwingungen die Haken 18 der Hebel 14 - 17 momentan auswärts bewegt werden können, wodurch Klinke 5 in unerwünschter Weise eingekuppelt werden könnte. Der zugehörige Schaft, welcher über das Gestänge 9 mitgenommen wird, verbleibt also solange in seiner Hoch- bzw. Tieffachstellung, bis gemäss dem Bindungsprogramm Klinke 5 wieder eingekuppelt wird.Then, together with the rightward movement of the lifting knife 25, the lever 91-93 is pivoted clockwise and the lever 86, 87 in the counterclockwise direction. Thus, the stop 83 is moved to the left so that the game A is canceled. The circuit board 23 is now in the left-hand, upper position in solid line in FIG. 1, in which the control levers 14-17 are in the operative position shown. The hooks 18 protrude into the path of the free end 61 of the coupled pawl 5 rotating with the shaft 1, as a result of which the end 61 runs onto one of the hooks 18. With further rotation according to arrow 66, pawl 5 is disengaged from shaft 1 and reaches position 5a shown in dashed lines in FIG. 1. The arm 17 is in contact with the fixed stop 54, on which it is held under the action of the tension spring 55. Since the parts 23, 14-17 are locked, it is prevented that, for example as a result of machine vibrations, the hooks 18 of the levers 14-17 can momentarily be moved outwards, as a result of which the pawl 5 could be engaged in an undesirable manner. The associated shaft, which is carried along via the linkage 9, therefore remains in its up or down position, until jack 5 is engaged again according to the binding program.

Die Entriegelung der Platine 23 aus dem Anschlag 83 geht folgendermassen vor sich. Zunächst wird das Hubmesser 25 nach links bewegt. Während dessen werden der Hebel 91 - 93 im Gegenzeigersinn, der Hebel 86, 87 im Uhrzeigersinn verschwenkt, wodurch der Anschlag 83 nach rechts bewegt und das Spiel A wieder hergestellt wird. Sobald das Hubmesser 25 seine linke Stellung ereicht hat, wird Platine 23 mittels des abwärtsbewegten Antriebszapfens 28 abwärts bewegt in die Position 26a, in der sie vom Hubmesser 25 je nach dem Programm ergriffen werden kann. Wenn das Hubmesser 25 Fig. 1 nach rechts läuft, wird z. B. Platine 23 mitgenommen. Dadurch werden die Enden 18 der Hebel 14 - 17 auswärts verschwenkt, so dass die Klinke 5 unter Wirkung der Zugfeder 60 wieder in die Welle 1 eingekuppelt wird. Bei der weiteren, absatzweisen Drehung der Welle 1 wird der Schaft wieder in die Tief- bzw. Hochfachstellung gewegt. Er wird so lange hin-und her bewegt, bis wieder die Klinke 5 ausgekuppelt wird. Dies geschieht auf die oben beschriebene Weise.The unlocking of the board 23 from the stop 83 proceeds as follows. First, the lifting knife 25 is moved to the left. In the meantime, the lever 91-93 is pivoted counterclockwise, the lever 86, 87 clockwise, whereby the stop 83 is moved to the right and the play A is restored. As soon as the lifting knife 25 has reached its left position, the board 23 is moved downward by means of the drive pin 28 moved down to the position 26a, in which it can be gripped by the lifting knife 25 depending on the program. If the lifting knife 25 Fig. 1 runs to the right, z. B. board 23 taken. As a result, the ends 18 of the levers 14-17 are pivoted outward, so that the pawl 5 is coupled back into the shaft 1 under the action of the tension spring 60. As shaft 1 rotates further in sections, the shaft is moved back into the low or high position. It is moved back and forth until the pawl 5 is disengaged again. This is done in the manner described above.

Dadurch, dass beim Verriegeln der Haken 82 der aufwärts zu bewegenden Platine 23 immer unter Spiel A hinter den Anschlag 83 geführt wird, ist dafür gesorgt, dass nicht etwa infolge von Maschinenschwingungen der Haken 82 mit der Fläche 96 gegen die Fläche 97 des Anschlags 83 schlagen kann. Haken 82 hintergreift vielmehr in jedem Fall den Anschlag 83. Andererseits ist in der Fig. 2 linken Position 83a des Anschlags 83 dafür gesorgt, dass nicht etwa infolge von Maschinenschwingungen die Enden 18 der Hebel 14 - 17 momentan auswärts geschwenkt und dadurch Klinke 5 in unerwünschter Weise eingekuppelt werden könnte.The fact that when the hook 82 of the board 23 to be moved upwards is always locked with play A behind the stop 83, it is ensured that the hook 82 does not hit against the surface 97 of the stop 83 with the surface 96 as a result of machine vibrations can. Rather, hook 82 engages behind the stop 83 in any case. On the other hand, in FIG. 2, left position 83a of the stop 83, it is ensured that the ends 18 of the levers 14-17 are not swiveled outward as a result of machine vibrations, and therefore pawl 5 is undesirable Way could be engaged.
