Description

Die Erfindung betrifft eine Einrichtung zum Speichern von fadenförmigem Material für den Schusseintrag bei Webmaschinen mit einer umlaufenden, das Material tragenden Scheibe und einer darauf gerichteten Düse zum Zuführen von Luft und Material. Im folgenden ist als fadenförmiges Material beispielsweise Garn angenommen.The invention relates to a device for storing thread-like material for weft insertion in weaving machines with a rotating disk carrying the material and a nozzle directed thereon for supplying air and material. In the following, for example, yarn is assumed as the thread-like material.

Bei einer bisherigen Speichereinrichtung dieser Art (DE-PS 2 215 003) wird das zu speichernde Garn durch eine quer zur Umlaufrichtung der Scheibe hin und her bewegte Zuführdüse auf diese in Schlingenform abgelegt. Das Garn wird nach der Speicherung im wesentlichen senkrecht zur Fläche der Tragscheibe von dieser abgezogen. Das Garn soll lediglich durch die Kraftwirkung der Zuführdüse auf der Tragscheibe festgehalten werden.In a previous storage device of this type (DE-PS 2 215 003), the yarn to be stored is deposited on it in a loop shape by a feed nozzle which is moved back and forth transversely to the direction of rotation of the disk. After being stored, the yarn is drawn off the support disk essentially perpendicular to the surface thereof. The yarn should only be held on the supporting disc by the force of the feed nozzle.

Die schlingenförmige Garnablage kann jedoch leicht in Unordnung geraten, so dass sich einzelne Schlingen übereinander legen können. Der Abzug des gespeicherten Garnes kann dadurch gestört werden, weil häufig mehrere, übereinander liegende Schlingen zu gleicher Zeit abgezogen werden können anstatt hintereinander. Bei dieser bekannten Ausführungsform lässt sich überdies Beginn und Ende der auf der Tragscheibe zu speichernden Fadenlänge nicht genau definieren; die Speicherlänge kann daher nur angenährert der bei der Webmaschine benötigten Eintragslänge angepasst werden. Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Hinsicht verbesserte Speichereinrichtung zu schaffen.However, the loop-shaped yarn deposit can easily become disordered, so that individual loops can overlap. The withdrawal of the stored yarn can be disturbed because often multiple loops lying one above the other can be removed at the same time instead of one after the other. In this known embodiment, moreover, the beginning and end of the thread length to be stored on the support disk cannot be precisely defined; the length of the memory can therefore only be approximated to the length of the entry required on the weaving machine. The object of the invention is to create a storage device which is particularly improved in this regard.

Die erfindungsgemässe Einrichtung ist gekennzeichnet durch wenigstens eine einzige, mit der Scheibe umlaufende, gegen sie bewegbare und das Material auf sie drückende Fadenklemme und durch eine Auflage auf der Tragscheibe, die zwischen der Fadenklemme und der Tragscheibe angeordnet ist zum Halten des Materials auf der Scheibe, wobei das Material zwischen Scheibe und Auflage gespeichert wird.The device according to the invention is characterized by at least one single thread clamp rotating with the disc, movable against it and pressing the material onto it, and by a support on the support disc which is arranged between the thread clamp and the support disc for holding the material on the disc, where the material is stored between the disc and the pad.

Durch die Fadenklemme lässt sich ein besonders genauer Zeitpunkt für den Beginn einer Speicherlänge auf der Tragscheibe definieren. Ferner lässt sich auch ein genauer Zeitpunkt für das Ende der Speicherlänge und zugleich für den Beginn des Schusseintrages und damit des Abzugs der gespeicherten Fadenablage definieren. Die Einrichtung eignet sich daher besonders für Luftdüsen-Webmaschinen, bei denen die Eintragslänge durch die Speicherlänge auf der Schussfadenspeichereinrichtung bestimmt werden soll.A particularly precise point in time for the beginning of a length of storage on the support disk can be defined by the thread clamp. Furthermore, a precise point in time for the end of the storage length and at the same time for the beginning of the weft insertion and thus the withdrawal of the stored thread deposit can also be defined. The device is therefore particularly suitable for air jet looms in which the entry length is to be determined by the length of the storage on the weft storage device.

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

  • Fig. 1 zeigt in Draufsicht und in schematischer Darstellung eine erfindungsgemäss ausgebildete Schussfadenspeichereinrichtung und - in kleinerem Massstab - eine zugehörige Webmaschine,
  • Fig. 2 ist eine zugehörige Vorderansicht, teilweise im Schnitt, unter Weglassung der Webmaschine und
  • Fig. 3 veranschaulicht eine zugehörige Ansicht nach Linie 111/111 in Fig. 2.
Further features emerge from the following description of exemplary embodiments in conjunction with the drawing and the claims.
  • 1 shows a top view and a schematic representation of a weft thread storage device designed according to the invention and - on a smaller scale - an associated weaving machine,
  • Fig. 2 is an associated front view, partly in section, with the weaving machine and omitted
  • FIG. 3 illustrates an associated view along line 111/111 in FIG. 2.

Die Webmaschine 1 besitzt zwei Wangen 2, 3, einen Kettbaum 4, Schäfte 5 und einen Warenbaum 6. Das Gewebe 7 läuft entsprechend Pfeil 8 vom Kettbaum 4 durch die Schäfte 5 hindurch zum Warenbaum 6.The weaving machine 1 has two cheeks 2, 3, a warp beam 4, shafts 5 and a fabric beam 6. The fabric 7 runs according to arrow 8 from the warp beam 4 through the shafts 5 to the fabric beam 6.

Das Schussgarn 11 wird mittels einer auf der Schussseite 71 angeordneten Hauptdüse 12 durch das von den Schäften 5 gebildete Webfach hindurch zu einer auf der Fangseite 72 angeordneten Saugdüse 13 geführt.The weft yarn 11 is guided by means of a main nozzle 12 arranged on the weft side 71 through the shed formed by the shafts 5 to a suction nozzle 13 arranged on the catch side 72.

An der Maschinenwange 2 ist ein Gestell 15 angebracht. In ihm ist eine in Fig. 2 vertikal stehende, während des Betriebes kontinuierlich vom Hauptantrieb der Webmaschine 1 angetriebene Welle 16 gelagert. Auf ihr ist eine Tragscheibe 17 für das zu speichernde Schussgarn 11 befestigt. Der Antrieb der Welle 16 und der Scheibe 17 erfolgt über ein Zahnriemenrad 18 und ein Getriebe 19.A frame 15 is attached to the machine cheek 2. A shaft 16, which is vertical in FIG. 2 and is continuously driven by the main drive of the weaving machine 1 during operation, is mounted in it. A support disk 17 for the weft yarn 11 to be stored is fastened on it. The shaft 16 and the disk 17 are driven via a toothed belt wheel 18 and a gear 19.

Die Tragscheibe 17 ist in ihrem inneren Bereich 21 vertieft, während sie in einem äusseren Bereich eine Erhöhung 22 (Fig. 2) aufweist. Die Scheibe 17 trägt einen ringscheibenförmigen Nadelfilz 23. Sein innerer Bereich 24 liegt in dem Vertiefungsbereich 21, während der äussere Bereich 25 in einer relativ zur Scheibe 17 schrägen Position gehalten ist.The support disk 17 is recessed in its inner region 21, while it has an elevation 22 (FIG. 2) in an outer region. The disk 17 carries an annular disk-shaped needle felt 23. Its inner area 24 lies in the depression area 21, while the outer area 25 is held in an oblique position relative to the disk 17.

In Fig. 2 oberhalb des Bereiches 24 des Filzes 23 ist eine Deckscheibe 26 angeordnet. Durch sie wird der Filz 23 niedergehalten und insbesondere seine innere Partie 24 nach unten gedrückt. Der äussere Bereich 25 wird durch die Erhöhung 22 mehr oder weniger in der Schrägstellung nach Fig. 2 gehalten.A cover disk 26 is arranged above the area 24 of the felt 23 in FIG. 2. The felt 23 is held down by it and in particular its inner part 24 is pressed down. The outer region 25 is more or less held in the inclined position according to FIG. 2 by the elevation 22.

In einer Nabe 27 der Druckscheibe 26 sind z.B. drei, um Schwenklager 28 schwenkbare Arme 81 bis 83 angeordnet, an denen je eine mit Druckfedern 29 versehene Klemme 31, 32, 33 gelagert ist. Jede Feder 29 ist bestrebt, die zugehörige Klemme 31 - 33 in Fig. 2 abwärts zu drücken. An den Armen 81 - 83 greifen ausserhalb ihrer Schwenklager 28 drei Zugfedern 75 - 77 an. Diese sind bestrebt, die Arme 81 bis 83 in Fig. 2 nach oben zu schwenken und damit die Klemmen 31 - 33 in der in Fig. 2 links dargestellten, bei Klemme 31 gezeichneten, wirkungslosen Stellung zu halten.In a hub 27 of the thrust washer 26, e.g. three arms 81 to 83 which can be pivoted about pivot bearings 28, on each of which a clamp 31, 32, 33 provided with compression springs 29 is mounted. Each spring 29 strives to push the associated clamp 31-33 downward in FIG. 2. Outside of their swivel bearings 28, three tension springs 75 - 77 act on the arms 81-83. These endeavor to pivot the arms 81 to 83 in FIG. 2 upward and thus to hold the clamps 31-33 in the ineffective position shown at the left in FIG.

Die Klemmen 31 - 33 laufen während des Betriebes zusammen mit den Teilen 17, 23, 26 entsprechend Pfeil 34 um. Eine in Fig. 2 darüber angeordnete, mit einem Nocken 36 ausgestattete Nockenscheibe 37 steht während des Betriebes still. An den Armen 81 - 83 angeordnete Rollen 38 laufen während des Betriebes auf der in Fig. 2 unteren Fläche der Nockenscheibe 37 ab. Wenn eine Rolle 38 über den Nocken 36 läuft, wird z.B. der Arm 82 in Fig. 2 abwärts geschwenkt, so dass die zugehörige Klemme 32 in die untere Klemmposition 32a gelangt. In dieser drückt Klemme 32 unter Durchtritt durch den zugehörigen, im Filz 23 bei den Klemmen angebrachten Ausschnitt 84 auf die Scheibe 17. Dadurch kann ein von einer ortsfesten Düse 41 eingeblasenes Fadenstück 51 des Schussfadens 11 auf der Scheibe 17 gehalten werden.The terminals 31-33 rotate together with the parts 17, 23, 26 according to arrow 34 during operation. A cam disk 37 arranged above it in FIG. 2 and equipped with a cam 36 stands still during operation. Rollers 38 arranged on the arms 81-83 run during operation on the lower surface of the cam disk 37 in FIG. When a roller 38 runs over the cam 36, e.g. the arm 82 is pivoted downward in FIG. 2 so that the associated clamp 32 reaches the lower clamp position 32a. In this clamp 32 presses on the pane 17 while passing through the associated cutout 84 provided in the felt 23 at the clamps. This allows a piece of thread 51 of the weft thread 11 blown in by a stationary nozzle 41 to be held on the pane 17.

Das Schussgarn 11 wird von einer nicht dargestellten Zumesstrommel abgezogen. Die Düse 41 ist durch einen Keil 42 geschützt, der in Drehrichtung der Tragscheibe 17 (Pfeil 34) vor der Düse 41 angeordnet ist. Durch den Keil 42 wird der äussere Bereich 25 der Filzscheibe 23 kurz vor der Aufblasstelle 92 angehoben, so dass das gezeichnete Fadenstück 51 auf die Tragscheibe 17 zu liegen kommt. Nach dem Auflegen des Fadens auf Scheibe 17 kann der Filzbereich 25 wieder mehr oder weniger von selbst abwärts klappen, so dass das Fadenstück 51 leicht von oben her gehalten werden kann.The weft yarn 11 is drawn off from a metering drum, not shown. The nozzle 41 is protected by a wedge 42 which is arranged in front of the nozzle 41 in the direction of rotation of the support disk 17 (arrow 34). By the wedge 42, the outer loading Rich 25 of the felt disk 23 is raised shortly before the inflation point 92, so that the drawn piece of thread 51 comes to rest on the support disk 17. After the thread has been placed on disk 17, the felt region 25 can fold down more or less of its own accord, so that the thread piece 51 can easily be held from above.

Die Wirkungsweise ist folgende.The mode of action is as follows.

Während des Webbetriebes laufen die Scheibe 17, der Filz 23 und die Klemmen 31 - 33 kontinuierlich entsprechend Pfeil 34 um. Aus Düse 41 bläst kontinuierlich ein Luftstrom, durch welchen Schussfaden 11 kontinuierlich auf Scheibe 17 in Form einer schlingenförmigen Fadenablage 51 abgelegt wird. Klemme 33 durchläuft die in Fig. 1 gezeichnete Position. Darauf läuft sie in Fig. 2 oberhalb des Keiles 42 an diesem vorbei und gelangt in die Stellung 33a. In diesr wird die Klemme infolge Auflaufens der zugehörigen Rolle 38 auf den Nocken 36 in Fig. 2 abwärts verschwenkt. Das Ende des gespeicherten Fadenstückes 51 wird dadurch festgeklemmt.During the weaving operation, the disk 17, the felt 23 and the clamps 31 - 33 continuously rotate according to arrow 34. An air stream continuously blows from nozzle 41, through which weft thread 11 is continuously deposited on disk 17 in the form of a loop-shaped thread deposit 51. Terminal 33 passes through the position shown in Fig. 1. It then runs past the wedge 42 in FIG. 2 and reaches position 33a. In this, the clamp is pivoted downward as a result of the associated roller 38 running onto the cam 36 in FIG. 2. The end of the stored piece of thread 51 is thereby clamped.

Während Klemme 33 von Position 33 in Stellung 33a läuft, läuft Klemme 32 von Position 32a in die Stellung 32b. Dabei verlässt die zugehörige Rolle 38 den Nocken 36 unter der Wirkung der angrenzenden Federn 75, 77. Das gespeicherte Fadenstück 51 bestimmter Länge wird dadurch freigegeben. Die Hauptdüse 12 erhält Druck, der Schusseintrag beginnt. Während die Tragscheibe 17 weiterläuft, wird die gespeicherte, genau definierte Fadenlänge 51 abgezogen. Zugleich wird ein nächster Fadenvorrat gleicher Länge zwischen den Klemmen 33 und 31 abgelegt.While terminal 33 is running from position 33 to position 33a, terminal 32 is running from position 32a to position 32b. The associated roller 38 leaves the cam 36 under the action of the adjacent springs 75, 77. The stored piece of thread 51 of a certain length is thereby released. The main nozzle 12 receives pressure, the weft insertion begins. While the support disk 17 continues to run, the stored, precisely defined thread length 51 is drawn off. At the same time, a next thread supply of the same length is deposited between terminals 33 and 31.

Der äussere Bereich 25 des Filzes 23 wird in dem Sektor 61 zwischen je zwei aufeinanderfolgenden Klemmen 32, 33 während des Speicher- bzw. Eintragsvorganges durch Keil 42 und den Strahl von Düse 41 mehr oder weniger in der oberen Schrägstellung (entsprechend Fig. 2 links) gehalten. Während des Schusseintrages kann gegebenenfalls eine leichte Bremswirkung auf den unter dem Filzbereich 25 befindlichen Schussfaden 51 erfolgen. Dadurch kann dieser während des Eintrages straff gehalten werden. Die Nockenscheibe 37 kann mittels Schrauben 93, 94 und eines Langloches 63 in eine gewünschte Position verschwenkt und fixiert werden.The outer area 25 of the felt 23 is more or less in the upper oblique position in the sector 61 between two successive clamps 32, 33 during the storage or entry process by wedge 42 and the jet from nozzle 41 (corresponding to FIG. 2 left) held. During the weft insertion, a slight braking effect on the weft thread 51 located under the felt area 25 can optionally take place. This allows it to be kept taut during the entry. The cam disk 37 can be pivoted and fixed into a desired position by means of screws 93, 94 and an elongated hole 63.

Die Schussfadenspeichervorrichtung kann auch bei einer anderen Webmaschinengattung als einer Luftdüsenmaschine verwendet werden.The weft storage device can also be used in a weaving machine type other than an air jet machine.

Bei einer abgewandelten Ausführungsform wird während ein und desselben Schusseintrages zunächst der gesamte Speichervorrat 51 verbraucht und zusätzlich ein kurzes Fadenstück unmittelbar aus der Düse 41 nachgezogen.In a modified embodiment, the entire storage supply 51 is initially consumed during one and the same weft insertion and, in addition, a short piece of thread is drawn directly from the nozzle 41.

Statt eines Filzes 23 kann auch eine andere, mit rauher Oberfläche versehene Auflage 23 zum Festhalten bzw. Auflegen der schlingenförmigen Fadenablage 51 benutzt werden oder eine gitterartige Auflage.Instead of a felt 23, it is also possible to use another support 23 provided with a rough surface for holding or placing the loop-shaped thread support 51 or a grid-like support.
