Description

Die Erfindung betrifft eine Schussfadenspeichervorrichtung für eine Webmaschine, mit einem Wickelkörper zum Aufwickeln des Schussfadens, welcher Wickelkörper aus einem exzentrisch zur Antriebsachse der Speichervorrichtung angeordneten, trommelförmigen Teil und mehreren, einen radial verstellbaren Wickelteil bildenden Bügeln besteht, die mit einem radial zum Wickelkörper stehenden Schenkel in dem trommelförmigen Teil gehalten sind, während der andere, im wesentlichen achsparallel zur Speicherachse verlaufende Schenkel gegen eine Grundscheibe des Wickelkörpers hin verläuft.The invention relates to a weft thread storage device for a weaving machine, with a winding body for winding up the weft thread, which winding body consists of a drum-shaped part arranged eccentrically to the drive axis of the storage device and a plurality of brackets forming a radially adjustable winding part, which has a leg radially to the winding body the drum-shaped part are held, while the other leg, which runs essentially axially parallel to the storage axis, runs against a base disk of the winding body.

Bei einer bisherigen Vorrichtung dieser Art (CH-PS 639 711) wird jeder Radialschenkel der Bügel in einer Bohrung des trommelförmigen Teiles mittels einer Klemmschraube gehalten. Der Axialschenkel verläuft bis unmittelbar gegen die Grundscheibe. Er kann diese berühren, ohne in ihr befestigt zu sein.In a previous device of this type (CH-PS 639 711), each radial leg of the bracket is held in a bore in the drum-shaped part by means of a clamping screw. The axial leg runs directly against the base plate. He can touch it without being attached to it.

Soll der Wickeldurchmesser des Wickelkörpers und damit die der Webbreite der zugehörigen Webmaschine entsprechende Länge der Speicherwicklung verändert werden, so ist die Klemmschraube bei jedem Radialschenkel zu lösen und der Bügel von Hand mehr oder weniger einzuschieben und in einer neuen Position mittels der Schraube wieder festzuklemmen. Diese Verstellung der Bügel erfordert relativ grosses Geschick von der Bedienungsperson der Webmaschine. In der Regel muss durch Probieren die neue Position des Bügels herausgefunden werden, welche der gewünschten Webbreite entspricht.If the winding diameter of the winding body and thus the length of the storage winding corresponding to the weaving width of the associated weaving machine are to be changed, the clamping screw on each radial leg must be loosened and the bracket pushed in more or less by hand and clamped in a new position by means of the screw. This adjustment of the bracket requires relatively great skill from the operator of the weaving machine. As a rule, the new position of the hanger which corresponds to the desired weaving width must be found out by trying.

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

Die Erfindung besteht darin, dass die Grundscheibe drehbar ausgebildet und mit mindestens einer spiralförmigen Nut versehen ist, in welche Axialschenkel der Bügel hineinragen.The invention consists in that the base plate is designed to be rotatable and is provided with at least one spiral groove, into which the axial limbs of the bracket project.

Hierdurch lässt sich erreichen, dass alle Bügel gemeinsam radial um ein im wesentlichen gleiches Mass verstellt werden können, indem die Grundplatte verdreht wird. Die Axialschenkel der Bügel werden dabei gemeinsam in radialer Richtung weiter nach innen oder aussen bewegt, je nachdem wie die Spiralnut verläuft. Zugleich werden die Radialschenkel der Bügel in der zugehörigen Bohrung der Wickeltrommel weiter nach innen bzw. aussen verschoben. Hiernach würden in der Regel die Radialschenkel der Bügel wieder festzuspannen sein. Dadurch lässt sich leicht eine neue Speicherlänge des Schussfadens einstellen.As a result, it can be achieved that all of the brackets can be adjusted radially by an essentially the same amount by rotating the base plate. The axial limbs of the stirrups are moved further inwards or outwards in the radial direction, depending on how the spiral groove runs. At the same time, the radial legs of the brackets are moved further inwards or outwards in the associated bore of the winding drum. After this, the radial limbs of the brackets would normally have to be tightened again. This makes it easy to set a new storage length for the weft thread.

Insbesondere wird es möglich, die Verstellung der Bügel als Feineinstellung für die Schusseintragslänge zu benutzen; zu welcher eine entsprechende Grobeinstellung gehört. Die Grobeinstellung lässt sich beispielsweise durch Wahl einer passenden Anzahl von Windungen auf dem Wickelkörper erzielen, die zu ein und derselben Schusseintragslänge gehört. Die zugehörige Feineinstellung lässt sich durch die geschilderte Verstellung der Bügel erzielen.In particular, it becomes possible to use the adjustment of the stirrups as a fine adjustment for the weft insertion length; to which a corresponding rough setting belongs. The rough adjustment can be achieved, for example, by selecting an appropriate number of turns on the winding former that belong to the same weft insertion length. The associated fine adjustment can be achieved by adjusting the bracket as described.

In einem zylindrischen Gehäuse 1 ist eine schematisch angedeutete Antriebswelle 2 der Speichervorrichtung 3 angeordnet, die über einen Zahnriementrieb 4 entsprechend Pfeil 5 angetrieben wird. Auf der Welle 2 ist ein Fadenzuführungsrohr 6 angebracht, das entsprechend Pfeil 7 angetrieben ist. Dabei wird der mit 8 bezeichnete Schussfaden gemäss Pfeil 9 zugeführt und in Form von Windungen 11 auf einen als Ganzes mit 12 bezeichneten Wickelkörper aufgewickelt. Zum Massenausgleich gegenüber dem Rohr 6 ist ein Stab 51 vorgesehen.A schematically indicated drive shaft 2 of the storage device 3 is arranged in a cylindrical housing 1 and is driven via a toothed belt drive 4 according to arrow 5. On the shaft 2, a thread feed tube 6 is attached, which is driven according to arrow 7. The weft thread designated 8 is fed according to arrow 9 and wound in the form of windings 11 onto a winding body designated as a whole as 12. A rod 51 is provided for mass balance with respect to the tube 6.

Während des Webbetriebes rotiert Scheibe 13 gemäss Pfeil 14 und lässt in jeder Zahnlücke 15 eine bestimmte Anzahl Windungen nach rechts durch. Ueber die Stirnseite 16 wird der Schussfaden während des Webens gemäss Pfeil 17 über Kopf abgezogen und in das Webfach einer zugehörigen, nicht dargestellten Webmaschine eingetragen.During weaving operation, disk 13 rotates according to arrow 14 and allows a certain number of turns to the right in each tooth gap 15. The weft thread is drawn off over the end face 16 during the weaving according to arrow 17 and entered into the shed of an associated weaving machine, not shown.

Der Wickelkörper 12 besteht aus einem mit seiner Achse 18 exzentrisch gegenüber der Achse 2 des Speichers 3 angeordneten, trommelförmigen Wickelteil 19 und beispielsweise sieben, im unteren Bereich des Teiles 19 angebrachten Bügeln 21. Jeder Bügel enthält einen im wesentlichen radial zum Teil 19 gerichteten Schenkel 22 und einen im wesentlichen parallel zu den Achsen 18,2 verlaufenden Axialschenkel 23. Jeder Schenkel 22 ragt in eine Ausnehmung 24 des Wickelteils 19, jeder Schenkel 23 erstreckt sich bis zu einer Grundscheibe 26 hin. Scheibe 26 ist unter Zwischenlage eines Kugellagers 60 drehbar auf dem Wickelteil 19 gelagert. Scheibe 26 besitzt einen gebogenen Schlitz 62, durch den eine Klemmschraube 61 in den Wickelteil 19 eingeschraubt ist. Nach Lösen der Schraube 61 (Fig. 5) kann die Scheibe 26 z. B. von Hand gedreht und in einer neuen Position mittels der Schraube 61 wieder festgeklemmt werden.The winding body 12 consists of a drum-shaped winding part 19 arranged with its axis 18 eccentrically with respect to the axis 2 of the store 3 and, for example, seven stirrups 21 attached in the lower region of the part 19. Each stirrup contains a leg 22 directed essentially radially to the part 19 and an axial leg 23 running essentially parallel to the axes 18, 2. Each leg 22 projects into a recess 24 in the winding part 19, each leg 23 extends up to a base plate 26. Disc 26 is rotatably supported on the winding part 19 with the interposition of a ball bearing 60. Disc 26 has a curved slot 62 through which a clamping screw 61 is screwed into the winding part 19. After loosening the screw 61 (Fig. 5), the disc 26 z. B. rotated by hand and clamped in a new position by means of the screw 61.

Die Scheibe 26 dargestellt ist, enthält eine durchgehend verlaufende, spiralförmige Nut 28. Die Enden 29 jedes Axialschenkels 23 ragen in die Spiralnut 28 und in eine zugehörige Radialnut 27. Durch Nut 27 werden die Enden 29 bei ihrer Radialbewegung geführt. Die Enden 31 der Radialschenkel 22 sind unter Zwischenlage eines Gummiringes 32 mittels einer stirnseitigen Scheibe 33 unter Verwendung einer Spannschraube 34 festgeklemmt.The disk 26 is shown, contains a continuous, spiral-shaped groove 28. The ends 29 of each axial leg 23 protrude into the spiral groove 28 and into an associated radial groove 27. The ends 29 are guided through their groove 27 during their radial movement. The ends 31 of the radial legs 22 are interposed Rubber ring 32 clamped by means of a front disc 33 using a clamping screw 34.

An dem Gehäuse 1 ist ein winkelförmiger Führungsteil 41 befestigt, der einen Schlitz 42 aufweist, in den die Zähne 40 der Separierscheibe 13 hineinragen. Dadurch wird der aus dem zylinderförmigen Wickelteil 19 und den Bügeln 23 bestehende Wickelkörper 3, der drehbar auf der Welle 2 gelagert ist, gegen Drehung gesichert.An angular guide part 41 is fastened to the housing 1 and has a slot 42 into which the teeth 40 of the separating disk 13 protrude. As a result, the winding body 3, which consists of the cylindrical winding part 19 and the brackets 23 and is rotatably mounted on the shaft 2, is secured against rotation.

Während des Webbetriebes ist die Anordnung beispielsweise so getroffen, dass jeweils fünf Windungen 11a in ein und dieselbe Zahnlücke 15a der Separierscheibe 13 gelangen und in Fig. 1 nach rechts abgezogen werden, wenn der zugehörige Zahn 40a in den trommelförmigen Teil 9 weggetaucht ist. Die fünf Windungen 11a enthalten beispielsweise eine Länge von 1.40 m, die gleich der gewünschten Webbreite ist.During the weaving operation, the arrangement is made, for example, in such a way that five turns 11a each get into one and the same tooth gap 15a of the separating disk 13 and are pulled off to the right in FIG. 1 when the associated tooth 40a is immersed in the drum-shaped part 9. The five turns 11a contain, for example, a length of 1.40 m, which is equal to the desired weaving width.

Soll beispielsweise eine Webbreite von 2 m auf dem Wickelkörper 3 gespeichert werden, so wird die Schraube 34 gelöst, so dass die Bügel 21 in den Schlitzen 24 gelockert sind. Darauf wird die Schraube 61 gelöst und die Scheibe 26 von Hand so verdreht, dass die Bügel 21 aufgrund der Spiralnut 28 in Fig. 2 weiter nach aussen bewegt werden. Der Verstellweg kann an den Marken 44 der Schenkel 22 abgelesen werden kann. In einer neuen, der Webbreite W = 2 m entsprechenden Position werden die Schrauben 61, 34 wieder angezogen, so dass die Scheibe 26 und die Bügel 21 wieder fest sitzen. Nunmehr kann der Webbetrieb mit der neuen Webbreite fortgesetzt werden.If, for example, a weaving width of 2 m is to be stored on the winding body 3, the screw 34 is loosened so that the stirrups 21 are loosened in the slots 24. The screw 61 is then loosened and the disk 26 is rotated by hand in such a way that the brackets 21 are moved further outwards due to the spiral groove 28 in FIG. 2. The adjustment path can be read from the marks 44 of the legs 22. In a new position corresponding to the weaving width W = 2 m, the screws 61, 34 are tightened again, so that the washer 26 and the stirrups 21 are firmly seated again. Now the weaving operation can be continued with the new weaving width.

Bei einer abgewandelten Ausführungsform ist statt einer einzigen, durchlaufenden Spiralnut 28 eine Anzahl von sich jeweils nur über einen Bruchteil des Umfangs erstreckenden Teilnuten 28a, b, c gemäss Fig. 6 vorgesehen, in denen z. B. jeweils zwei Bügel 21 mit ihren Enden 29 geführt sind. Zweckmässig sind weitere Teilnuten 28d, e in der Scheibe 26a als Blindnuten angebracht, damit die Scheibe 26a leicht in jeder Drehstellung benutzt werden kann. In den Nuten 28d, e sind bei dem Beispiel keine Bügelenden 29 geführt.In a modified embodiment, instead of a single, continuous spiral groove 28, a number of partial grooves 28a, b, c each extending only over a fraction of the circumference is provided according to FIG. B. two brackets 21 are guided with their ends 29. Other partial grooves 28d, e are expediently provided in the disk 26a as blind grooves, so that the disk 26a can be easily used in any rotational position. In the example, no temple ends 29 are guided in the grooves 28d, e.
