Description

Die Erfindung betrifft eine Einrichtung zum Reinigen des Rietes einer Webmaschine, z. B. einer Luftstrahlwebmaschine.The invention relates to a device for cleaning the reed of a weaving machine, for. B. an air jet loom.

Zum Reinigen des Rietes einer Webmaschine muss dieses unter Umständen aus der Maschine herausgenommen und separat von Hand oder mit einer Bürstmaschine behandelt werden. Anschliessend müssen die Kettfäden neu in das Riet eingezogen werden, bevor es in die Maschine eingesetzt werden kann. Diese Reinigungsart ist kompliziert und zeitraubend.To clean the reed of a weaving machine, it may have to be removed from the machine and treated separately by hand or with a brushing machine. The warp threads must then be pulled back into the reed before it can be used in the machine. This type of cleaning is complicated and time consuming.

Eine direkte Reinigung des Rietes innerhalb der Webmaschine selbst ist bisher nur mittels Handbürste oder Druckluft möglich. Eine solche Reinigung, bei der die Kettfäden im Riet eingezogen bleiben können, ist zwar weniger zeitaufwendig, aber für das Bedienungspersonal beschwerlich. Die Bedienungsperson muss vorsichtig zu Werk gehen, damit die eingezogenen Kettfäden nicht verletzt werden. Der Schmutz kann dann mittels einer Saugvorrichtung abgesaugt werden.A direct cleaning of the reed inside the weaving machine itself has so far only been possible using a hand brush or compressed air. Such cleaning, in which the warp threads can remain drawn in the reed, is less time-consuming, but difficult for the operating personnel. The operator must go to work carefully so that the drawn-in warp threads are not injured. The dirt can then be sucked off using a suction device.

Der Erfindung liegt die Aufgabe zugrunde, eine Reinigungseinrichtung für das Riet einer Webmaschine zu schaffen, die das Riet, insbesondere die Lamellen im Bereich des Führungskanals für den Schussfaden, ohne grösseren Zeitaufwand einer Bedienungsperson wirkungsvoll von Verunreinigungen wie z.

Das Gerät 21 befindet sich mit seinem durch die Lamelle 52 gebildeten, unteren Ende oberhalb der Stafettendüsen 17.The cleaning device 21 is now raised in the inclined position according to FIG. 3 with the guides 56, 57 over the upper reed beam 81 and then lowered. Beam 81 now forms a pivot point for the cleaning device 21, about which the device is pivoted under its gravity in FIG. 3 according to arrow 82 into the operating position according to FIG. 4, in which the axes 61, 62 and the entire device 21 are vertical. The support roller 47 is supported against the slats 78. The device 21, with its lower end formed by the slat 52, is located above the relay nozzles 17.

Nunmehr wird Ventil 27 in Fig. 2 gegen die Wirkung der Feder 25 nach rechts gedrückt (Pfeil 26), so dass die beiden Motoren 23, 41 Druckluft erhalten. Der Endlostrieb 35 bewegt sich entsprechend Pfeil 83, die Bürsten 45, 46 laufen gemäss Pfeil 84. Das Gerät 21 läuft langsam auf dem Riet 12 entsprechend Pfeil 85 in Fig. 2 nach rechts. Die Lamellen 78 werden durch die Bürsten 45, 46 gereinigt, der Schmutz kann in einen unteren Sammelraum 86 fallen.Valve 27 in FIG. 2 is now pressed against the action of spring 25 to the right (arrow 26), so that the two motors 23, 41 receive compressed air. The endless drive 35 moves according to arrow 83, the brushes 45, 46 run according to arrow 84. The device 21 runs slowly on the reed 12 according to arrow 85 in FIG. 2 to the right. The fins 78 are cleaned by the brushes 45, 46, the dirt can fall into a lower collecting space 86.

Wenn ein an dem Gerät 21 angebrachter Fühler 87 auf einen ortsfesten, an der Stütze 72 befestigten Anschlag 88 auftrifft, wird eine Schaltstange 91 (Fig. 5) entgegen der Wirkung einer Zugfeder 92 relativ zum Gehäuse 22 nach links bewegt, wodurch ein um 93 schwenkbarer Block 94 gemäss Pfeil 95 verschwenkt wird. Dadurch werden eine an dem Block 94 angelenkte Schaltstange 96 und ein daran befestigter Riegel 99 gemäss Pfeil 97 abwärtsbewegt, wodurch Ventil 27 freigegeben und unter der Wirkung der Feder 25 in Fig. 5 nach links bewegt wird. Leitung 24 wird geschlossen, Die Motoren 23, 41 stehen still, der Reinigungs-. vorgang ist beendet.When a sensor 87 attached to the device 21 strikes a stationary stop 88 fastened to the support 72, a switching rod 91 (FIG. 5) is moved to the left relative to the housing 22 against the action of a tension spring 92, as a result of which a pivotable by 93 Block 94 is pivoted according to arrow 95. As a result, a switching rod 96 articulated on the block 94 and a bolt 99 fastened thereon are moved downward in accordance with arrow 97, as a result of which valve 27 is released and moved to the left in FIG. 5 under the action of spring 25. Line 24 is closed, the motors 23, 41 stand still, the cleaning. process is finished.

Gegebenenfalls kann der im Sammelraum 86 anfallende Schmutz durch eine in Fig. 2 gestrichelt angedeutete Absaugdüse 101 entfernt werden.If necessary, the dirt accumulating in the collecting space 86 can be removed by means of a suction nozzle 101 indicated by dashed lines in FIG. 2.

Der Durchlassquerschnitt der Zuführungsleitungen zu den beiden Motoren 23, 41 kann durch zwei Drosselventile 103, 104 (Fig. 2) verstellt werden, so dass auch die Drehzahl der Motoren und damit die Geschwindigkeit der Fortbewegung des Gerätes 21 auf dem Riet 12 wie auch die Rotation der Bürsten 45, 46 eingestellt werden können. Das Gerät lässt sich mittels eines Handgriffes 106 leicht wieder vom Riet abheben, um dieses nach Wegnahme der Stützen 71, 72 wieder in die Betriebsposition abzusenken. Hiernach kann der Webbetrieb forgesetzt werden.The passage cross section of the feed lines to the two motors 23, 41 can be adjusted by two throttle valves 103, 104 (FIG. 2), so that the speed of the motors and thus the speed of the movement of the device 21 on the reed 12 as well as the rotation the brushes 45, 46 can be adjusted. The device can be easily lifted off the reed by means of a handle 106 in order to lower it again into the operating position after the supports 71, 72 have been removed. After that, the web operation can be continued.

Bei einer abgewandelten Ausführungsform sind statt Luftmotoren 23, 41 Elektromotoren benutzt. Gegebenenfalls kann die Fortbewegung des Gerätes 21 auf dem Riet 12 entsprechend Pfeil 85 und/oder die Drehbewegung der Bürsten 45, 46 mittels einer von Hand zu betätigenden Antriebsvorrichtung, etwa eines Kurbeltriebes ausgeführt werden. Statt der Reinigung mittels Reinigungsbürsten 45, 46 kann gegebenenfalls auch Druckluft durch die zwischen den Lamellen 78 befindlichen, verschmutzten Schlitze (Rohre) 107 geleitet werden.In a modified embodiment, electric motors are used instead of air motors 23, 41. If necessary, the movement of the device 21 on the reed 12 in accordance with arrow 85 and / or the rotary movement of the brushes 45, 46 can be carried out by means of a manually operated drive device, for example a crank drive. Instead of cleaning by means of cleaning brushes 45, 46, compressed air can optionally also be passed through the dirty slots (pipes) 107 located between the fins 78.

Die Bürsten 45, 46 können auch entgegen Pfeil 84 rotieren, wenn ein oberer Sammelraum 86a vorgesehen ist. Die Reinigung kann auch z. B. unter Aufsprühen einer Reinigungsflüssigkeit auf die rotierenden Bürsten 45, 46 erfolgen (Nassreinigung).The brushes 45, 46 can also rotate counter to arrow 84 if an upper collecting space 86a is provided. The cleaning can also be done e.g. B. by spraying a cleaning liquid onto the rotating brushes 45, 46 (wet cleaning).
