Abstract

The holding device is provided with a shaped body for raising and lowering the plate-shaped element located within the fixedly mounted support. The shaped body may be in the form of a wedge shaped body or in the form of an eccentric. Suitable means are provided for holding the wedge shaped body in place. Raising and lowering of the plate-shaped elements allows the electrical contact elements to be raised and lowered to adapt to the operating conditions of the weaving machine.

Description

Die Erfindung betrifft eine Haltevorrichtung für die Schienen, insbesondere Kontaktschienen des Kettfadenwächters einer Webmaschine, mit einem die Schienen umgreifenden, plattenförmigen Teil, der an einem feststehenden Träger verschiebbar angeordnet ist.The invention relates to a holding device for the rails, in particular contact rails of the warp thread monitor of a weaving machine, with a plate-shaped part encompassing the rails, which is arranged displaceably on a fixed support.

Bei einer bisherigen Vorrichtung dieser Art (DE-A Nr. 1760945 und US-A Nr. 3584659) ist der plattenförmige Teil auf dem Träger mittels Langloch und zugehöriger Klemmschraube verstellbar und feststellbar. Bei grosser Webbreite der Webmaschine werden mehrere solche Träger mit verschiebbaren, plattenförmigen Teilen gebraucht, um die sich über die ganze Webbreite erstreckenden Schienen des Kettfadenwächters zu halten. Mit der bekannten Verstelleinrichtung ist es erschwert, bei den einzelnen Haltern und plattenförmigen Teilen jeweils die gleiche Höhenstellung herbeizuführen, so dass die Schienen des Kettfadenwächters über die ganze Webbreite exakt gleiche Position haben und in der Regel horizontal verlaufen. Von der Position der Kontaktschienen des Kettfadenwächters hängt die Fallhöhe der zugehörigen Abstellamellen ab.In a previous device of this type (DE-A No. 1760945 and US-A No. 3584659), the plate-shaped part on the carrier is adjustable and fixable by means of an elongated hole and associated clamping screw. If the weaving machine has a large weaving width, several such carriers with displaceable, plate-shaped parts are needed in order to hold the rails of the warp thread monitor which extend over the entire weaving width. With the known adjusting device, it is difficult to bring about the same height position in the individual holders and plate-shaped parts, so that the rails of the warp thread monitor have exactly the same position over the entire weaving width and generally run horizontally. The drop height of the associated parking slats depends on the position of the contact rails of the warp thread monitor.

Es besteht nun das Bedürfnis, den plattenförmigen Teil eines jeden Trägers des Kettfadenwächters leicht und exakt auf gleiche Höhe einstellen zu können, wie bei den anderen Trägern, so dass die betreffenden Schienen überall gleiche Höhe aufweisen. Die Höhe der Schienen sowie die Fallhöhe der Abstellamellen bei Kettfadenbruch lässt sich dadurch variieren und den jeweiligen Verhältnissen (Position des Spannbaumes der Webmaschine, Höhe des geöffneten Webfaches, Art des verwendeten Garnes) anpassen.There is now a need to be able to easily and exactly adjust the plate-shaped part of each carrier of the warp thread monitor to the same height as the other carriers, so that the rails in question have the same height everywhere. The height of the rails and the drop height of the storage slats in the event of warp thread breakage can be varied and adapted to the respective conditions (position of the tensioning tree of the weaving machine, height of the open shed, type of yarn used).

Die Erfindung besteht darin, dass zwischen plattenförmigen Teil und Träger ein im wesentlichen keilförmiges Schiebeelement geschaltet ist, das entlang einer an dem plattenförmigen Teil oder/ und dem Träger befindlichen Schräge stufenhaft einstellbar ist. Hierdurch lässt sich die Position der plattenförmigen Teile bei jedem Träger und damit die Stellung der Schienen insbesondere der Kontaktschienen des Kettfadenwächters exakt gleich einstellen. Dadurch lassen sich insbesondere Fehlabstellungen durch den Kettfadenwächter vermeiden.The invention consists in that an essentially wedge-shaped sliding element is connected between the plate-shaped part and the carrier and can be adjusted in stages along a slope located on the plate-shaped part and / or the carrier. As a result, the position of the plate-shaped parts on each carrier and thus the position of the rails, in particular the contact rails of the warp thread monitor, can be set exactly the same. In particular, incorrect positioning by the warp thread monitor can thereby be avoided.

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

  • Fig. 1 zeigt in Vorderansicht eine erfindungsgemäss ausgebildete Haltevorrichtung,
  • Fig. 2 ist ein zugehöriger Schnitt nach Linie 11 - II in Fig. 1, und
  • Fig. 3 zeigt die Vorrichtung nach Fig. 1 in einer anderen Position.
Further features emerge from the following description of exemplary embodiments in conjunction with the claims and the drawing.
  • 1 shows a front view of a holding device designed according to the invention,
  • Fig. 2 is an associated section along line 11 - II in Fig. 1, and
  • Fig. 3 shows the device of Fig. 1 in a different position.

Das Webmaschinengestell enthält eine in Schussrichtung verlaufende Stange 1 von ovalem Querschnitt, an der mehrere U-förmige Halter 2 mittels Schrauben 3 und Spannkeil 4 befestigt sind. In jeden Rahmen 2 ist in Fig. 1 und 2 von oben ein Träger 5 eingeschoben. Er enthält in seinem unteren Teil eine schräg verlaufende Leiste 5a, während er im oberen Teil aus zwei parallelen Wandungen 5b besteht.The weaving machine frame contains a rod 1 of oval cross-section running in the weft direction, to which several U-shaped holders 2 are fastened by means of screws 3 and clamping wedge 4. 1 and 2, a support 5 is inserted into each frame 2 from above. In its lower part it contains a sloping bar 5a, while in the upper part it consists of two parallel walls 5b.

Zwischen die Wandungen 5b ist ein plattenförmiger Teil 6 geschoben, der Füsse 7 aufweist. Das in Fig. 1 untere Ende der Füsse 7 liegt auf einer Geraden 10, die in Fig. 1 gestrichelt angedeutet ist.A plate-shaped part 6, which has feet 7, is pushed between the walls 5b. The lower end of the feet 7 in FIG. 1 lies on a straight line 10, which is indicated by dashed lines in FIG. 1.

Die Leiste 5a besitzt eine Verzahnung 8 in welche Zähne 9 greifen, die am unteren Ende eines Schiebekeiles 11 angebracht sind. Das obere Ende 12 des Schiebekeiles 11 bildet eine Führung für die auf der Geraden angeordneten Füsse 7. An dem in Fig. 1 linken Ende weist der Schiebekeii 11 eine Nase 12 auf, die zwischen die beiden Wandungen 5b ragt.The strip 5a has a toothing 8 in which teeth 9 engage, which are attached to the lower end of a sliding wedge 11. The upper end 12 of the sliding wedge 11 forms a guide for the feet 7 arranged on the straight line. At the left end in FIG. 1, the sliding wedge 11 has a nose 12 which projects between the two walls 5b.

Der Schiebekeil 11 ist als Formkörper in die getriebliche Verbindung (Wirkungsverbindung) zwischen Träger 5 und plattenförmigem Teil 6 geschaltet. Beim Verschieben des Keiles 11 in Fig. 1 nach rechts wird dieser zweckmässig durch Einstecken eines Werkzeuges in eine Bohrung 15 etwas aus der Verzahnung 8 herausgehoben und gemäss Pfeil 16 nach rechts geschoben. Dabei bewegt er sich unter den Füssen 7 hinweg, so dass die Platte 6 dabei angehoben wird.The sliding wedge 11 is connected as a molded body in the gear connection (operative connection) between the carrier 5 and the plate-shaped part 6. When the wedge 11 is moved to the right in FIG. 1, it is expediently lifted out of the toothing 8 by inserting a tool into a bore 15 and pushed to the right according to arrow 16. He moves under the feet 7, so that the plate 6 is raised.

In der Platte 6 sind in Schlitzen 17 als Ganzes mit 18 bezeichnete Kontaktschienen geführt, während Führungsschienen 19 in Schlitzen 21 des Trägers 5 gehalten sind. Die Kontaktschienen 18 dienen zum Abstellen der Webmaschine bei Abfallen einer Abstellamelle 22 infolge Bruches eines Kettfadens 23. Die Führungsschienen 19 dienen dazu, die auf die Kontaktschiene 18 aufgereihten Lamellen 22 in Abstand voneinander zu halten, indem die Lamellenfüsse 24 zwischen je zwei Führungsschienen 19 gehalten sind. Der dem Webfach 51 entsprechende Abstand der Kettfäden 23 oberhalb der Stange 1 ist mit A bezeichnet.In the plate 6, contact rails, designated as a whole by 18, are guided in slots 17, while guide rails 19 are held in slots 21 of the carrier 5. The contact rails 18 serve to shut down the weaving machine when a parking slat 22 falls as a result of breakage of a warp thread 23. The guide rails 19 serve to keep the slats 22 lined up on the contact rail 18 at a distance from one another by holding the slat feet 24 between two guide rails 19 each . The distance of the warp threads 23 above the rod 1 corresponding to the shed 51 is designated by A.

Nach Verschieben des Keiles 11 im Rahmen der in dem Träger 5 angebrachten Öffnung 26 gelangt der Keil 11 z.B. in die Position 11 nach Fig. 3, in der die Platte 6 in der höheren Stellung 6a positioniert ist. Diese entspricht dem in Fig. 3 angenommenen, grösseren Abstand B der Kettfäden 23 bei grösserem Webfach 52. Die Kontaktschienen sind in der Position 18a. Die Fallzeit einer Lamelle 22 ist im Falle eines Kettfadenbruches gleich wie bei der Position nach Fig. 1, da in beiden Positionen der der Fallhöhe der Lamellen 22 gleiche Abstand C zwischen Kontaktschiene 18 und oberem Ende des zugehörigen Schlitzes der Lamellen 22 gleich ist.After moving the wedge 11 in the frame of the opening 26 made in the carrier 5, the wedge 11 reaches e.g. 3, in which the plate 6 is positioned in the higher position 6a. This corresponds to the larger distance B of the warp threads 23 assumed in FIG. 3 with a larger shed 52. The contact rails are in position 18a. The fall time of a slat 22 in the event of a warp thread break is the same as in the position according to FIG. 1, since in both positions the fall height of the slats 22 has the same distance C between the contact rail 18 and the upper end of the associated slot of the slats 22.

Während der Rahmen 2 z.B. aus metallischem Werkstoff, z.B. AI-Guss besteht, bestehen der Träger 5 und die Platte 6 aus Kunststoff, z.B. aus Polyamid oder Polytetrafluoräthylen. Sowohl der Träger 5 als auch die Platte 6 sind bei 31 in einer Führung des Rahmens 2 gehalten. Durch das Gewicht der Schienen 18,19 werden die Teile in der Zeichnung nach unten gedrückt, so dass auch die Zähne 9 ständig in der Verzahnung 8 gehalten sind und der Keil 11 nicht etwa nach links abrutschen kann.While the frame 2 consists, for example, of a metallic material, for example cast aluminum, the support 5 and the plate 6 are made of plastic, for example made of polyamide or polytetrafluoroethylene. Both the carrier 5 and the plate 6 are held at 31 in a guide of the frame 2. The parts in the drawing are pressed downward by the weight of the rails 18, 19, so that the teeth 9 are also constantly held in the toothing 8 and the wedge 11 cannot slide to the left.

Durch die Verzahnung 8 ist eine stufen hafte Einstellung des Keiles 11 bei jedem Träger 5 des Kettfadenwächters zu erzielen. Gegebenenfalls können Marken, z. B. Zahlen an den einzelnen Lücken der Verzahnung 8 angebracht werden, so dass sich leicht bei jedem Rahmen 5 bzw. Keil 11 die gleiche Stellung über die ganze Webbreite der Webmaschine erzielen lässt, wobei die Kontaktschienen 18 auf exakt gleicher Höhe stehen und horizontal verlaufen.Through the teeth 8 a gradual setting of the wedge 11 can be achieved with each carrier 5 of the warp thread monitor. If necessary, brands, e.g. B. numbers are attached to the individual gaps in the toothing 8, so that the same position can easily be achieved over the entire width of the weaving machine for each frame 5 or wedge 11, the contact rails 18 being at exactly the same height and running horizontally.

Die Anordnung ist so getroffen, dass sowohl der Keil 11 auf der Schräge 29 bzw. der Verzahnung 8 wie auch die Platte 6 auf dem Keil 11 formschlüssig aufliegen. Klemmteile wie Schrauben oder dergleichen sind nicht erforderlich. Die Anordnung lässt sich besonders leicht verstellen und den jeweils vorliegenden Verhältnissen anpassen. Bei einer abgewandelten Bauart kann z.B. die Schräge 29 am Träger 5 fortfallen. Die Verzahnung 8 verläuft dann horizontal. Die durch die Füsse 7 gebildete Schräge entsprechend der Geraden 10 wird dann eine passende, andere Steigung aufweisen. Der Keil 11 kann verschieden gestaltet sein. Es muss wenigstens an einem der Teile 5, 6 eine Schrägge angebracht sein, durch welche bei Verschieben des zwischen den Teilen 5 und 6 wirksamen Schiebeelementes 11 eine Höhenverstellung der Platte 6 erfolgt.The arrangement is such that both the wedge 11 on the bevel 29 or the toothing 8 and the plate 6 rest on the wedge 11 in a form-fitting manner. Clamping parts such as screws or the like are not required. The arrangement is particularly easy to adjust and adapt to the prevailing conditions. With a modified design, e.g. the bevel 29 on the carrier 5 is omitted. The toothing 8 then runs horizontally. The slope formed by the feet 7 corresponding to the straight line 10 will then have a suitable, different slope. The wedge 11 can be designed differently. At least one of the parts 5, 6 must be provided with an incline, by means of which the height of the plate 6 is adjusted when the sliding element 11 acting between the parts 5 and 6 is moved.
