Description

Die Erfindung betrifft eine Nadelbandwebmaschine gemäss Ober­gebriff des Anspruches 1.The invention relates to a needle ribbon loom according to the preamble of claim 1.

Nadelbandwebmaschinen der eingangs genannten Art sind mehr­fach bekannt, so beispielsweise aus den US-PSen 3 064 689 sowie 3 901 285. Das hierbei verwendete Rädergetriebe besteht aus einem Kegelradgetriebe, wobei ein Kegelradsegment an einer Welle angeordnet ist, die mit dem Hebelgetriebe in Ver­bindung steht. Ein zweites, kleineres Kegelrad ist an der Welle befestigt, die mit der Schussnadel in Verbindung steht. Mit einem solchen Getriebe lassen sich beliebig grosse Schwenkwinkel der Schussnadel erzeugen. Das Getriebe hat allerdings den entscheidenden Nachteil, dass jeweils nur wenige Zähne in Eingriff stehen, sodass es grossem Ver­schleiss unterliegt. Dadurch ergeben sich die Nachteile gerin­ger Standzeiten des Getriebes, ungenaue Bewegungsabläufe, grosse Lärmentwicklung. Ueberdies bedarf ein solches Kegelrad­getriebe einer laufenden Schmierung mit Schmiermitteln, so­dass es in einem entsprechenden Gehäuse untergebracht werden muss.Needle ribbon looms of the type mentioned are known several times, for example from US Pat. Nos. 3,064,689 and 3,901,285. The gear mechanism used here consists of a bevel gear mechanism, a bevel gear segment being arranged on a shaft which is connected to the lever mechanism. A second, smaller bevel gear is attached to the shaft, which is connected to the weft needle. With such a gear, any large swivel angle of the weft needle can be generated. However, the gearbox has the decisive disadvantage that only a few teeth are meshed, so that it is subject to great wear. This results in the disadvantages of short gear life, inaccurate movement sequences, and high levels of noise. In addition, such a bevel gear requires continuous lubrication with lubricants, so that it must be housed in a corresponding housing.

Aus der CH-PS 633 331 oder aus der WO 85/01524 sind andere Nadelbandwebmaschinen bekannt, die die oben beschriebenen Nachteile zum Teil dadurch beheben, dass ein Rädergetriebe entfällt und das Hebelgetriebe bis zur Welle geführt ist, an der die Schussnadel angeordnet ist. Solche Nadelbandwebma­schinen weisen einen geringen Verschleiss auf, haben somit hohe Standzeiten und zeichnen sich durch Geräuscharmut und Genauigkeit aus. Allerdings sind der Schwenkbewegung der Schussnadel Grenzen gesetzt, sodass diese einen Schwenkwinkel von höchstens 90° ausführen kann.From CH-PS 633 331 or from WO 85/01524 other needle ribbon looms are known which partially overcome the disadvantages described above by eliminating a gear train and guiding the lever gear up to the shaft on which the weft needle is arranged. Such needle ribbon looms have low wear, thus have a long service life and are characterized by low noise and accuracy. However, the pivotal movement of the Weft needle set limits, so that it can execute a swivel angle of at most 90 °.

Aufgabe der Erfindung ist es, eine Nadelbandwebmaschine der eingangs genannten Art so auszubilden, dass die erwähnten Nachteile vermieden werden.The object of the invention is to design a needle ribbon loom of the type mentioned at the outset in such a way that the disadvantages mentioned are avoided.

Die Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Dadurch, dass das Räderge­triebe als Ketten-, Riemen- oder insbesondere Zahnriemenge­triebe ausgebildet ist, verteilt sich der Kraftangriff auf eine grössere Anzahl von Zähnen, wodurch der Verschleiss ei­nes solchen Getriebes erheblich vermindert wird. Damit erge­ben sich hohe Standzeiten, eine grosse Genauigkeit und Ge­räuscharmung. Insbesondere wenn ein Riemengetriebe verwendet wird, entfallen überdies noch Schmiermittelprobleme, da sol­che Getriebe trocken laufen können, wodurch sich eine weitere wesentliche Vereinfachung der Nadelbandwebmaschine ergibt. Mit einer solchen Nadelbandwebmaschine können somit wesent­lich höhere Antriebsleistungen (beispielsweise über 1500 U/Min.) erreicht werden.The object is achieved according to the invention by the characterizing features of claim 1. Because the gear train is designed as a chain, belt or, in particular, toothed belt gear, the force application is distributed over a larger number of teeth, as a result of which the wear of such a gear is considerably reduced. This results in a long service life, great accuracy and low noise. In particular, if a belt transmission is used, lubrication problems are also eliminated since such transmissions can run dry, which results in a further substantial simplification of the needle ribbon weaving machine. With such a needle ribbon weaving machine, significantly higher drive powers (for example over 1500 rpm) can be achieved.

Der mit der vorliegenden Nadelbandwebmaschine erzielbare grös­sere Schwenkwinkel (beispielsweise 120°) der Schussnadel er­möglicht es, den Hub einer Wirknadel zur Abbindung der ein­getragenen Schussfadenschlaufe kleiner zu wählen, wodurch sich eine schönere Kantenbildung ergibt. Der grössere Schwenk­winkel der Schussnadel bringt den Schussfaden bereits beim Eintrag bis fast zur Gewebeanschlagkante. Dadurch wird der Schussfaden weniger durch das Webblatt belastet, sodass das Gewebe in höherer Qualität herstellbar ist.The larger swivel angle (for example 120 °) of the weft needle that can be achieved with the present needle ribbon weaving machine makes it possible to select a smaller stroke of a knitting needle for tying off the weft thread loop, which results in a nicer edge formation. The larger swivel angle of the weft needle brings the weft thread almost to the fabric stop edge as soon as it is inserted. As a result, the weft is less stressed by the reed, so that the fabric can be produced in higher quality.

Vorteilhafte Ausführungsformen der Nadelbandwebmaschine sind in den Ansprüchen 2 bis 5 beschrieben.Advantageous embodiments of the needle ribbon loom are described in claims 2 to 5.

Ansich ist es möglich, die Koppelstange des Hebelgetriebes an einem Kurbelarm einer Welle anzulenken, die ein Zahnrad des Rädergetriebes trägt. Vorteilhafter ist jedoch eine Ausge­staltung nach Anspruch 2. Dies ermöglicht insbesondere auch eine Weiterbildung der Nadelbandwebmaschine nach Anspruch 3, wodurch sich eine besonders einfache Spannvorrichtung für den Zahnriemen, Riemen oder die Kette des Rädergetriebes er­gibt.In itself, it is possible to link the coupling rod of the lever mechanism to a crank arm of a shaft which carries a gear wheel of the gear mechanism. However, an embodiment according to claim 2 is more advantageous. In particular, this also enables a further development of the needle ribbon loom according to claim 3, which results in a particularly simple tensioning device for the toothed belt, belt or chain of the gear train.

Je nach Uebersetzungsverhältnis und Einstellung des Räderge­triebes und des Hebelgetriebes können die verschiedensten Schwenkbewegungen der Schussnadel eingestellt werden. Vorteil­haft ist jedoch eine Ausgestaltung nach Anspruch 4, mit einer Schwenkbewegung der Schussnadel von 80° bis 180°, vorzugs­weise 120°.Depending on the gear ratio and setting of the gear mechanism and the lever mechanism, the most varied pivoting movements of the weft needle can be adjusted. However, an embodiment according to claim 4 is advantageous, with a pivoting movement of the weft needle of 80 ° to 180 °, preferably 120 °.

Es können Schussnadeln der verschiedensten Form zum Einsatz kommen, vorteilhaft ist jedoch eine solche gemäss Anspruch 5.A wide variety of weft needles can be used, but one according to claim 5 is advantageous.

Die Nadelbandwebmaschine kann ein Hebelgetriebe der verschie­densten Art aufweisen, insbesondere auch solche gemäss der CH-PS 633 331 und der WO 85/01524.The needle ribbon weaving machine can have a lever gear of the most varied types, in particular also those according to CH-PS 633 331 and WO 85/01524.

Ein schematisches Ausführungsbeispiel der erfindungsgemässen Nadelbandwebmaschine wird nachfolgend anhand der Zeichnungen näher beschrieben, dabei zeigen:

  • Figur 1 eine Nadelbandwebmaschine in Seitenan­sicht; und
  • Figur 2 die Nadelbandwebmaschine der Figur 1 im Grundriss und teilweise geschnitten.
A schematic embodiment of the needle ribbon loom according to the invention is described in more detail below with reference to the drawings, in which
  • Figure 1 shows a needle ribbon loom in side view; and
  • Figure 2 shows the needle ribbon loom of Figure 1 in plan and partially cut.

Die in den Figuren 1 und 2 schematisch dargestellte Nadelband­webmaschine enthält eine Hauptantriebswelle 2, an der ein Schussnadelantrieb 4, ein Webblattantrieb 6, ein Wirknadelan­trieb 8 und ein Fachbildeantrieb 10 angeschlossen sind. Fer­ner sind Kettfäden 12, das Kettfach 14 und ein gewobenes Band 16 angedeutet.The needle ribbon loom shown schematically in FIGS. 1 and 2 contains a main drive shaft 2, to which a weft needle drive 4, a reed drive 6, a knitting needle drive 8 and a shedding drive 10 are connected. Warp threads 12, the warp pocket 14 and a woven band 16 are also indicated.

An der Hauptantriebswelle 2 ist eine Scheibe 18 angeordnet, die einen in einer schwalbenschwanzförmigen Nut 20 radial verstellbar geführten Kurbelzapfen 22 enthält, sodass die Exzentrizität des Kurbelzapfens einstellbar ist. An dem Kur­belzapfen 22 ist eine Pleuelstange 24 angeschlossen, die über einen Gelenkbolzen 26 an einem Schwinghebel 28 befestigt ist, der drehfest mit einer Welle 30 verbunden ist.A disk 18 is arranged on the main drive shaft 2 and contains a crank pin 22 which is guided in a radially adjustable manner in a dovetail-shaped groove 20, so that the eccentricity of the crank pin can be adjusted. A connecting rod 24 is connected to the crank pin 22 and is fastened via a hinge pin 26 to a rocker arm 28 which is connected in a rotationally fixed manner to a shaft 30.

Eine im Schwinghebel 28 angeordnete Längsführung 32 dient zur Einstellung der wirksamen Hebellänge des Schwinghebels 28. An der Welle 30 ist weiter ein Arm 34 drehfest angeord­net, der an seinem freien Ende ein Webblatt 36 trägt.A longitudinal guide 32 arranged in the rocker arm 28 is used to adjust the effective lever length of the rocker arm 28. An arm 34 is also arranged on the shaft 30 in a rotationally fixed manner and carries a reed 36 at its free end.

An der Welle 30 des Webblattantriebes 6 ist weiter eine Schwinge 38 drehfest befestigt, an der eine Koppelstange 40 gelenkig angeschlossen ist, die wiederum mit einer Schwinge 42 gelenkig verbunden ist, welche am Schussnadelantrieb 4 vorhanden ist. Diese Schwinge 42 ist drehfest mit einer Welle 44 verbunden, welche eine weitere Schwinge 46 trägt, an der eine weitere Koppelstange 48 angeschlossen ist, welche die Verbindung zu einem Rädergetriebe 50 herstellt, über das eine vertikale Welle 52 angeschlossen ist. Letztere trägt am obe­ren Ende die in das Kettfach 14 eingreifende Schussnadel 54.On the shaft 30 of the reed drive 6, a rocker 38 is also non-rotatably attached, to which a coupling rod 40 is articulated, which in turn is articulated to a rocker 42 which is provided on the weft needle drive 4. This rocker 42 is non-rotatably connected to a shaft 44 which carries a further rocker 46, to which a further coupling rod 48 is connected, which establishes the connection to a gear train 50, via which a vertical shaft 52 is connected. The latter carries the weft needle 54 which engages in the warp compartment 14 at the upper end.

Das Rädergetriebe 50 ist als Kettengetriebe oder vorzugsweise als Zahnriemengetriebe ausgebildet. Es weist ein grosses Zahn­rad 56 auf, das an einem Exzenter 58 gelagert ist, der wiederum um seine Exzenterachse 60 schwenkbar angeordnet ist. Mittels einer Feststellschraube 62 kann der Exzenter 58 in seiner jeweiligen Lage arretiert werden. Die Exzenteranord­nung dient zum Spannen einer Kette oder vorzugsweise eines Zahnriemens 64, welcher das grosse Zahnrad 56 mit einem kleinen Zahnrad 66 verbindet, welches an der Welle 52 der Schussnadel 54 befestigt ist. Das grosse Zahnrad 56 weist einen Exzenterbolzen 68 auf, an dem die Koppelstange 48 des Hebelgetriebes angeschlossen ist. Mit Hilfe des Räderge­triebes 50 wird die beschränkte Schwenkbewegung des Hebelge­triebes derart übersetzt, dass die Schussnadel einen grossen Schwenkweg von vorzugsweise ungefähr 120° ausführen kann. Im gezeigten Beispiel weist die Schussnadel beispielsweise einen gabelförmigen Kopf 70 zum Erfassen und Eintragen einer Schuss­fadenschlaufe 72 in das Kettfach 14 auf.The gear transmission 50 is designed as a chain transmission or preferably as a toothed belt transmission. It has a large gear wheel 56 which is mounted on an eccentric 58, which in turn is arranged pivotably about its eccentric axis 60. The eccentric 58 can be locked in its respective position by means of a locking screw 62. The eccentric arrangement serves for tensioning a chain or preferably a toothed belt 64, which connects the large gear 56 with a small gear 66, which is fastened to the shaft 52 of the weft needle 54. The large gear 56 has an eccentric pin 68 to which the coupling rod 48 of the lever gear is connected. With the help of the gear mechanism 50, the limited pivoting movement of the lever mechanism is translated in such a way that the weft needle can execute a large pivoting path of preferably approximately 120 °. In the example shown, the weft needle has, for example, a fork-shaped head 70 for grasping and inserting a weft loop 72 into the warp pocket 14.

In den Figuren 1 und 2 ist weiter der Wirknadelantrieb 8 ge­zeigt, welcher eine an der Hauptantriebswelle 2 angeordnete Kurvenscheibe 74 besitzt, an der ein Mitnehmer 76 eines zwei­armigen Schwinghebels 78 angreift. Eine Feder 80 drückt den Mitnehmer 76 an die Kurvenscheibe 74. An dem dem Mitnehmer 76 abgewandten Ende des Schwinghebels 78 ist eine Wirknadel 82 befestigt, die in bekannter Weise an einer Seite des her­zustellenden Bandes angreift und zum Abbinden der mittels der Schussnadel 54 in das Kettfach 14 eingetragenen Schuss­fadenschlaufen 72 dient.FIGS. 1 and 2 also show the knitting needle drive 8, which has a cam 74 arranged on the main drive shaft 2, on which a driver 76 of a two-armed rocker arm 78 engages. A spring 80 presses the driver 76 against the cam 74. At the end of the rocking lever 78 facing away from the driver 76, a knitting needle 82 is fastened, which acts in a known manner on one side of the band to be produced and for tying it into the warp pocket by means of the weft needle 54 14 registered weft loops 72 is used.

Der ebenfalls an der Hauptantriebswelle 2 angeschlossene Fach­bildeantrieb 10 enthält ein einstufiges Getriebe 84, welches aus einer Schnecke 86, die mit der Hauptantriebswelle 2 ver­bunden ist, und einem Schneckenrad 88 gebildet ist, welches auf einer Nebenantriebswelle 90 sitzt, an der verschiedene Exzenter 92 befestigt sind, die in bekannter, nicht näher dargestellter Weise Schäfte antreiben.The tray drive 10, which is also connected to the main drive shaft 2, contains a single-stage gear 84 which is formed from a worm 86 which is connected to the main drive shaft 2 and a worm wheel 88 which is seated on a secondary drive shaft 90 to which various eccentrics 92 are fastened which drive shafts in a known, not shown manner.

Der im vorliegenden Beispiel gezeigte Anschluss der Schuss­nadeln an ein Hebelgetriebe lässt sich auch bei anderen Aus­führungsformen der Hebelgetriebe mit Vorteil einsetzen, so beispielsweise bei jenen der CH-PS 633 331 und der WO 85/01524.The connection of the weft needles to a lever mechanism shown in the present example can also be used advantageously in other embodiments of the lever mechanism, for example in those of CH-PS 633 331 and WO 85/01524.

Nadelbandwebmaschinen haben in der Regel mehr als eine Web­stelle, wobei jede Webstelle gegebenenfalls zwei gegeneinan­der arbeitende Schussnadeln aufweisen kann, die jeweils einen Teil der Breite der Gewebebahn überfahren. Bei solchen Nadel­bandwebmaschinen kann für jede Schussnadel ein Rädergetriebe der vorliegenden Art vorgesehen sein.As a rule, needle ribbon looms have more than one weaving point, each weaving point possibly having two weft needles working against one another, each of which traverses part of the width of the fabric web. In such needle ribbon looms, a gear mechanism of the present type can be provided for each weft needle.
