Description

Die Erfindung betrifft eine Schusseintragvorrichtung zur Umrüstung einer Schützenwebmaschine auf eine schützenlose Webmaschine, mit zwei entgegengesetzt bewegbaren und von beiden Seiten in ein Webfach einbringbaren Fadengreifern, die jeweils an einem Zahnband befestigt sind, das in Eingriff mit einem mittels einer Antriebskette mit wechselnder Umlaufrichtung angetriebenen Kettenrad steht, das mit einer gleichsinnig umlaufenden Antriebswelle der Webmaschine über eine Bewegungsumsetzeinrichtung gekoppelt ist, die einen an der Antriebswelle befestigten Kurbelarm enthält.The invention relates to a weft insertion device for converting a rifle loom to a defenseless weaving machine, with two thread grippers that can be moved in opposite directions and inserted into a shed from both sides, each of which is fastened to a toothed belt which is in engagement with a chain wheel driven by means of a drive chain with an alternating direction of rotation , which is coupled to a drive shaft of the loom rotating in the same direction via a movement conversion device which contains a crank arm fastened to the drive shaft.

Schusseintragvorrichtungen mit den vorstehend genannten Merkmalen sind durch die DE-A 2 807 920 und die BE-A 867 817 bekannt. Die bekannten Konstruktionen können jedoch den hier bei modernen Webmaschinen mit grosser Betriebsgeschwindigkeit gestellten Anforderungen an die Stabilität der Bewegungsumsetzeinrichtung und die damit zusammenhängende Betriebssicherheit jedoch nicht genügen. Es müssen hier zwei nicht masselos ausführbare Fadengreifer mit grosser Geschwindigkeit und mit relativ grosser Genauigkeit bis zur Webfachmitte bewegt und wieder aus dem Webfach herausbewegt werden. Die bekannten Schusseintragvorrichtungen sind ausserdem auf bestimmte Webmaschinen zugeschnitten und lassen sich nicht bei Webmaschinen unterschiedlicher Fabrikate einsetzen.Weft insertion devices with the features mentioned above are known from DE-A 2 807 920 and BE-A 867 817. However, the known constructions cannot meet the requirements placed on the stability of the movement conversion device and the associated operational safety in modern weaving machines with high operating speed. Two thread grippers, which cannot be carried out masslessly, have to be moved to the center of the shed at high speed and with relatively high accuracy and moved out of the shed again. The known weft insertion devices are also tailored to certain weaving machines and cannot be used in weaving machines of different makes.

Der Erfindung liegt die Aufgabe zugrunde, die Bewegungsumsetzeinrichtung einer zur Umrüstung einer Schützenwebmaschine auf eine schützenlose Webmaschine dienenden Schusseintragvorrichtung so auszubilden, dass sie an die unterschiedlichen umzurüstenden Maschirientypen anpassbar ist und auch bei hohen Betriebsgeschwindigkeiten eine einwandfreie Funktion gewährleistet.The invention is based on the object of designing the movement conversion device of a weft insertion device used to convert a shuttle loom to a defenseless weaving machine in such a way that it can be adapted to the different types of machine to be converted and that it functions properly even at high operating speeds.

Die gestellte Aufgabe wird mit einer Schusseintragvorrichtung der eingangs genannten Art erfindungsgemäss dadurch gelöst, dass die Bewegungsumsetzeinrichtung einen Hebel aufweist, der ein um einen stationären Zapfen verschwenkbares eines Ende hat, der in seinem Mittelbereich einen Gelenkzapfen trägt, der in einen Längsschlitz-eines mit dem Kurbelarm gekoppelten Lenkers ragt, und dessen anderes Ende über einen Lenker mit einem längsbewegbar gelagerten Schlitten gekoppelt ist, mit welchem die Antriebskette verbunden ist.The object is achieved according to the invention with a weft insertion device of the type mentioned at the outset in that the movement conversion device has a lever which has one end which can be pivoted about a stationary pin and which has a pivot pin in its central region which fits into a longitudinal slot - one with the crank arm coupled link protrudes, and the other end is coupled via a link to a longitudinally movable carriage to which the drive chain is connected.

Mit der erfindungsgemäss ausgebildeten Vorrichtung wird mittels Zahnbändern als äquivalent zu Antriebsketten ein einwandfreier Schusseintrag bei hohen Umdrehungszahlen der Antriebswelle erzielt, wobei mit den vorstehend angeführten kennzeichnenden Merkmalen die für die Übersetzung der relativ hohen Umdrehungszahl der Antriebswelle erforderliche Stabilität der Bewegungsumsetzeinrichtung erreicht ist. Der Hebel der Bewegungsumsetzeinrichtung ist über einen Lenker mit dem stabil geführten Schlitten gekoppelt. Der Ansatz des Kurbelarmes im Mittelbereich des Hebels ist für die geforderte Stabilität der Bewegungsumsetzeinrichtung wesentlich und bedeutet ausserdem, dass Toleranzen im Kurbelarmbereich keine merkliche Vergrösserung ihrer Auswirkung auf die Bewegungstoleranzen des stabil geführten Schlittens haben können.With the device designed according to the invention, a perfect weft insertion at high revolutions of the drive shaft is achieved by means of toothed belts as equivalent to drive chains, the stability of the motion conversion device required for the translation of the relatively high revolutions of the drive shaft being achieved with the above-mentioned characteristic features. The lever of the motion conversion device is coupled to the stable guided slide via a handlebar. The approach of the crank arm in the middle region of the lever is essential for the required stability of the movement conversion device and also means that tolerances in the crank arm region cannot have a noticeable increase in their effect on the movement tolerances of the stably guided slide.

Durch die Umrüstung einer Schützenwebmaschine mit einer Schusseintragvorrichtung gemäss der Erfindung gestaltet sich der Maschinenbetrieb erheblich geräuschärmer. Auch wird durch diesen Antrieb in den Endstellungen und Bewegungsumkehrstellungen der Tragbänder ein kurzzeitiger Stillstand dieser Bänder erreicht, durch welchen einerseits die Übergabe eines Schussfadens vom einen Greifer auf den anderen in der Fachmitte sowie das Erfassen des Anfangs eines Schussfadens durch den einen der beiden Greifer ausserhalb des Faches begünstigt wird.By retrofitting a shuttle loom with a weft insertion device according to the invention, the machine operation is considerably quieter. This drive also achieves a brief standstill of these belts in the end positions and reversal of the movement of the carrier tapes, through which on the one hand the transfer of a weft thread from one gripper to the other in the center and the detection of the start of a weft thread by one of the two grippers outside of the Subject is favored.

Nachfolgend wird ein Ausführungsbeispiel einer erfindungsgemäss ausgebildeten Schusseintragvorrichtung anhand der beiliegenden Zeichnungen näher erläutert.An exemplary embodiment of a weft insertion device designed according to the invention is explained in more detail below with reference to the accompanying drawings.

Im einzelnen zeigen:

  • Fig. 1 eine Vorderansicht der beiden Antriebseinrichtungen für die beiden Fadengreifer;
  • Fig. 2 + 3 eine Seitenansicht einer der beiden Antriebseinrichtungen bei zwei unterschiedlichen Antriebsstellungen der Vorrichtung.
In detail show:
  • Figure 1 is a front view of the two drive devices for the two thread grippers.
  • Fig. 2 + 3 is a side view of one of the two drive devices with two different drive positions of the device.

In den Figuren sind nur die erfindungswesentlichen Teile der Schusseintragvorrichtung zusammen mit Teilen des Webmaschinengestelles dargestellt. Alle anderen Teile der Webmaschine sind nicht dargestellt. Es ist auch auf eine Darstellung der für die Erfindung nicht wesentlichen Schussfadenvorratsspulen, der Schneidvorrichtung für den Schussfaden und der Steuereinrichtung zum Öffnen und Schliessen der Fadengreifer verzichtet worden.In the figures, only the parts of the weft insertion device essential to the invention are shown together with parts of the weaving machine frame. All other parts of the weaving machine are not shown. There is also no illustration of the weft thread bobbins which are not essential to the invention, the cutting device for the weft thread and the control device for opening and closing the thread grippers.

Aus Fig. 1 sind die beiden Endabschnitte 10 und 11 eines Webmaschinengestells ersichtlich, an denen obere und untere Haltearme 12, 13 bzw. 14, 15 befestigt sind. An beiden Enden der Webmaschine sind spiegelbildlich gleich ausgebildete Antriebseinrichtungen 16 und 17 für einen ersten Fadengreifer 18 und einen zweiten Fadengreifer 19 angeordnet. Beide Fadengreifer 18 und 19 sind jeweils an einem Tragband 20 oder 21 befestigt und werden mit Hilfe dieser in nicht näher dargestellter Weise durch Rollen geführten Tragbänder entgegengesetzt zueinander von gegenüberliegenden Seiten in ein Webfach der nicht dargestellten Webmaschine eingeführt, so dass sie sich in der Fachmitte treffen, wo eine Übergabe eines Schussfadenanfangs vom ersten Greifer 18 auf den zweiten Greifer 19 erfolgt, worauf dann die beiden Greifer wieder in entgegengesetzter Richtung voneinander entfernt und aus dem Webfach herausbewegt werden. Auf diese Weise wird mittels der beiden Greifer 18 und 19 ein Schussfaden von der einen zur anderen Seite einer Kettfadenanordnung durch das gebildete Webfach hindurchgeführt und anschliessend in bekannter Weise eingebunden.1 shows the two end sections 10 and 11 of a weaving machine frame, to which upper and lower holding arms 12, 13 and 14, 15 are fastened. At both ends of the weaving machine, drive devices 16 and 17 for a first thread gripper 18 and a second thread gripper 19 of identical design are arranged in mirror image. Both thread grippers 18 and 19 are each fastened to a carrying belt 20 or 21 and, with the aid of these carrying belts, which are guided by rollers in a manner not shown in detail, are introduced opposite one another from opposite sides into a shed of the weaving machine, not shown, so that they meet in the center of the compartment , where a transfer of a weft thread start from the first gripper 18 to the second gripper 19 takes place, whereupon the two grippers are then moved away from each other in the opposite direction and moved out of the shed. In this way, a weft thread is passed from one side to the other of a warp thread arrangement through the formed shed by means of the two grippers 18 and 19 and then integrated in a known manner.

Da beide Antriebsvorrichtungen 16 und 17 spiegelbildlich gleich ausgebildet sind, wird im folgenden nur eine der beiden Antriebsvorrichtungen näher erläutert. Jede der beiden Antriebsvorrichtungen 16 und 17 wird von einer im Endteil 10 oder 11 des Webmaschinengestelles gelagerten, gleichsinnig bewegbaren Antriebswelle 22 bzw. 23 der nicht dargestellten Fachbildungseinrichtung der Webmaschine angetrieben. Zu diesem Zweck ist auf das vorstehende Ende der Antriebswelle 22 ein Kurbelarm 24 mit einem im Kurbelarm zwecks einer Hubverstellung verstellbar angeordneten Kurbelzapfen 25 befestigt. Der Kurbelzapfen 25 bewegt einen Lenker 26, der einen nicht näher dargestellten Längsschlitz aufweist, in welchem ein Führungszapfen 27 gleitet, der im Mittelbereich eines Hebels 28 angeordnet ist. Wie Fig. 1 zeigt, ist der Hebel 28 gekröpft. Wie am besten aus Fig. 2 ersichtlich ist, ist der Hebel mit seinem einen Ende 28.1 auf einem auf dem Endteil 10 des Webmaschinengestells stationären Zapfen 30 verschwenkbar gelagert. Am anderen freien Ende des Hebels 28 ist das eine Ende eines Lenkers 29 angelenkt, dessen anderes Ende mit einem Schlitten 31 gelenkig verbunden ist.Since both drive devices 16 and 17 are of identical design in mirror image, will follow in the following which only one of the two drive devices explained. Each of the two drive devices 16 and 17 is driven by a drive shaft 22 or 23, which is mounted in the end part 10 or 11 of the weaving machine frame and can be moved in the same direction, of the shedding device of the weaving machine, not shown. For this purpose, a crank arm 24 is attached to the projecting end of the drive shaft 22 with a crank pin 25 which is adjustably arranged in the crank arm for the purpose of stroke adjustment. The crank pin 25 moves a link 26, which has a longitudinal slot, not shown, in which a guide pin 27 slides, which is arranged in the central region of a lever 28. 1, the lever 28 is cranked. As can best be seen from FIG. 2, the lever is pivotably mounted with its one end 28.1 on a pin 30 which is stationary on the end part 10 of the weaving machine frame. At the other free end of the lever 28, one end of a link 29 is articulated, the other end of which is articulated to a slide 31.

Der Schlitten 31 ist auf zwei parallelen Führungsstangen 32 längsverschiebbar gelagert. An ihm sind die beiden Enden 33.1 und 33.2 (Fig. 1) einer Antriebskette 33 befestigt, die über ein unteres Umlenkrad 34 und ein oberes Umlenkrad 35 geführt ist. Das obere Umlenkrad 35 ist koaxial mit einem Kettenrad 36 fest verbunden, das mit dem den einen Greifer 18 tragenden Tragband 20 in Eingriff steht.The slide 31 is mounted on two parallel guide rods 32 so as to be longitudinally displaceable. The two ends 33.1 and 33.2 (FIG. 1) of a drive chain 33 are fastened to it, which is guided via a lower deflection wheel 34 and an upper deflection wheel 35. The upper deflection wheel 35 is coaxially connected to a chain wheel 36, which is in engagement with the carrier belt 20 carrying the gripper 18.

Der Kurbelarm 24, der Hebel 26, der Schwenkhebel 28 und der Lenker 29 bilden eine Bewegungsumkehreinrichtung, mit welcher die gleichsinnige Bewegung der Antriebswelle 22 in eine hin- und hergehende Längsbewegung des Schlittens 31 und von dort aus in eine hin- und hergehende Drehbewegung des Kettenrades 36 übertragen wird. Die Schusseintragvorrichtung mit ihren beiden Antriebseinrichtungen 16 und 17 lässt sich nachträglich an praktisch jede mit Schützen arbeitende Webmaschine anbringen, wobei die Anpassung an die unterschiedlichen Webmaschinentypen und Webmaschinengrössen durch eine entsprechende Anpassung nach Länge und Kröpfungsgrad der Teile der Bewegungsumsetzeinrichtungen erfolgt.The crank arm 24, the lever 26, the pivot lever 28 and the link 29 form a movement reversing device with which the same-directional movement of the drive shaft 22 into a reciprocating longitudinal movement of the carriage 31 and from there into a reciprocating rotary movement of the chain wheel 36 is transmitted. The weft insertion device with its two drive devices 16 and 17 can be retrofitted to practically any weaving machine working with shooters, the adaptation to the different weaving machine types and weaving machine sizes being carried out by a corresponding adjustment according to the length and degree of cranking of the parts of the movement conversion devices.
