Description
Fadenabschneidvorrichtung an Webstühlen mit Schusswechselapparat. Den Gegenstand der vorliegenden Erfin dung bildet eine Fadenabschneidvorrichtung an Webstühlen mit Schusswechselapparat.
Auf der beiliegenden Zeichnung ist eine beispielsweise Ausführungsform des Erfin dungsgegenstandes dargestellt, und zwar zeigt: Fig. 1 eine Seitenansicht der Vorrichtung, Fig. 2 eine Ansicht von links in Fig. 1 unter Weglassung und Schnitt einiger Teile, Fig. 3 einen Vertikalschnitt nach der Linie A-A der Fig. 2.
Ein Aufnahmestück 1 weist eine Bohrung 2 auf, mit welcher es an eine Stange 3 gesteckt und an derselben mittelst einer Schraube 4 festgehalten ist. Die Stange 3 ist in einen mit Schusswechselapparat ausgestatteten Web stuhl eingebaut. Das Aufnahmestück 1 besitzt zwei seitliche Platten 5, in denen eine Achse 6 drehbar gelagert ist. Auf dieser sitzt eine am Umfang mit Schmirgelbelag 7 verkleidete Walze 8 fest. An den über die Platten 5 vorstehenden Endteilen der Achse 6 sitzt einerseits ein- Stellring 9 und anderseits eine am Umfang mit spitzen Zähnen versehene Antriebsscheibe 10 fest. An einem am Auf nahmestück 1 festsitzenden Träger 11 sind mittelst zweier Bolzen 12 zwei aneinander liegende Flachfedern 13 befestigt.
Zwischen den selben ist ein um die Walze 8 gelegtes endloses Band- 14 hindurchgeführt, welches von der Walze 8 in umlaufende Bewegung versetzt wird. Des fernem ist am Aufnahmestück 1 ein Scherenhebelarm 15 festgeschraubt, wel cher angelenkt, einen zweiten Scherenhebel arm 16 trägt. Dieser steht unter Wirkung einer Schraubenfeder 17.
Die Wirkungsweise des beschriebenen Fadenabschneiders ist folgende Der seitliche Rand des vom Webstuhl hergestellten Stoffes wird, in Fig. 2 betrachtet, rechts vom Aufnahmestück 1 und damit an den beiden Flachfedern 13 vorbeibewegt, wobei das Antriebsrad 10 in den sich über dasselbe hinwegbewegenden Stoff eingreift, von diesem gedreht- und mit dem Band 14 in Umlauf versetzt wird. Hierbei kommen die seitlich am Stoffrand vorstehenden Faden enden auf das Band 14 aufzuliegen, mit welchem sie zwischen den Flachfedern 13 hindurchbewegt werden, bis dieselben von der Schere 15, 16 abgeschnitten werden.
Die Schere wird zweckmässigerweise durch die Ratiere des Webstuhles betätigt, mit welcher sie durch ein am Scherenhebel 16 angreifendes, über eine Leitrolle 18 geführtes Zugorgan 19 verbunden ist.
Thread cutting device on looms with gunshot apparatus. The subject of the present invention is a thread cutting device on looms with a gun gun.
In the accompanying drawing, an exemplary embodiment of the subject of the invention is shown, namely: Fig. 1 is a side view of the device, Fig. 2 is a view from the left in Fig. 1 with the omission and section of some parts, Fig. 3 is a vertical section according to the Line AA of FIG. 2.
A receiving piece 1 has a bore 2 with which it is plugged onto a rod 3 and held on the same by means of a screw 4. The rod 3 is installed in a chair equipped with a gunshot web. The receiving piece 1 has two lateral plates 5 in which an axis 6 is rotatably mounted. A roller 8 covered on the circumference with an emery coating 7 sits firmly on this. On the end parts of the axle 6 protruding beyond the plates 5, an adjusting ring 9 on the one hand and a drive pulley 10 provided on the circumference with pointed teeth on the other hand are firmly seated. On a fixed on the take-up piece 1 carrier 11 two adjacent flat springs 13 are fastened by means of two bolts 12.
Between the same, an endless belt 14 placed around the roller 8 is passed, which is set in rotating motion by the roller 8. Furthermore, a scissors lever arm 15 is screwed to the receiving piece 1, wel cher hinged, a second scissors lever arm 16 carries. This is under the action of a helical spring 17.
The mode of operation of the thread cutter described is as follows: The lateral edge of the fabric produced by the loom, viewed in FIG. 2, is moved to the right of the receiving piece 1 and thus past the two flat springs 13, with the drive wheel 10 engaging the fabric moving over the same this is rotated and set with the belt 14 in circulation. The threads protruding laterally on the edge of the fabric come to rest on the band 14 with which they are moved between the flat springs 13 until they are cut off by the scissors 15, 16.
The scissors are expediently actuated by the ratchet of the loom, with which they are connected by a pulling element 19 which engages on the scissor lever 16 and is guided via a guide roller 18.
