Description

Die Erfindung bezieht sich auf ein Verfahren und eine Webmaschine zur Handhabung eines Schußfadens nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method and a weaving machine for handling a weft thread according to the preamble of patent claim 1.

Bei Webmaschinen ist es bekannt, neben den eigentlichen Gewebekettfäden an den Geweberändern sogenannte Hilfskettfäden vorzusehen. Die Hilfskettfäden werden in einem Hilfsriet geführt. Zwischen den Gewebekettfäden und den Hilfskettfäden ist ein mehr oder weniger großer Abstand vorgesehen, so daß in diesem Zwischenraum z.B. eine Einlegevorrichtung und eine Schneidevorrichtung angeordnet werden kann. Die Aufgabe der Hilfskettfäden, in Ihrer Gesamtheit auch als Fangleiste bezeichnet, ist, den Schußfaden aufzunehmen und dessen Spannung sicherzustellen, so daß der Schußfaden durch die Schneidevorrichtung ordentlich abgeschnitten werden kann. Dies wird u. a. auch in Verbindung mit einer sogenannten Streckduse erreicht, die den Schußfaden beim Austritt aus dem Schußkanal erfaßt und unter Spannung hält.In the case of weaving machines, it is known to provide so-called auxiliary warp threads in addition to the actual warp threads on the fabric edges. The auxiliary warp threads are guided in an auxiliary reed. A greater or lesser distance is provided between the fabric warp threads and the auxiliary warp threads, so that e.g. an insertion device and a cutting device can be arranged. The task of the auxiliary warp threads, also referred to in its entirety as a catch strip, is to take up the weft thread and to ensure its tension, so that the weft thread can be cut off properly by the cutting device. This will u. a. also achieved in connection with a so-called stretch nozzle, which detects the weft thread as it exits the weft channel and keeps it under tension.

Die Fangleiste weist gewöhnlich eine Breite von einigen Zentimetern auf und gilt, nachdem sie ihre Aufgabe erfüllt hat, als Abfallprodukt. Es sammelt sich also eine nicht geringe Menge an Stoffresten an, so daß beim Webvorgang ein erhöhter Materialverbrauch, d. h. Kett- und Schußfadenverbrauch und damit höhere Kosten entstehen, als unbedingt notwendig sind.The catch rail is usually a few centimeters wide and, once it has fulfilled its purpose, is considered a waste product. So it accumulates a not insignificant amount of fabric remnants, so that an increased material consumption, ie. H. Warp and weft consumption and thus higher costs than are absolutely necessary.

Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zur Handhabung des Schußfadens bei Webmaschinen der eingangs genannten Art vorzuschlagen, bei welchem auf den Einsatz der Fangleisten verzichtet werden kann.The object of the invention is to propose a method and a device for handling the weft thread in weaving machines of the type mentioned in the introduction, in which the use of the catch strips can be dispensed with.

Gelöst wird diese Aufgabe durch die technische Lehre des Anspruchs 1.This problem is solved by the technical teaching of claim 1.

Wesentliches Merkmal der Erfindung ist, daß der Einsatz von Fangleisten gänzlich vermieden wird und die Webmaschine über eine Absaugvorrichtung verfügt, welche im Bereich der Einlegevorrichtung vor dem ersten Schußwächter angeordnet ist.An essential feature of the invention is that the use of catch strips is completely avoided and the weaving machine has a suction device which is arranged in the area of the insertion device in front of the first weft guard.

Die Absaugvorrichtung befindet sich im frei gewordenen Zwischenraum zwischen Einlegekopf/Schneidevorrichtung und dem ersten Schußfadenwächter, welcher Zwischenraum beim Stand der Technik durch die Hilfskettfäden (Fangleisten) eingenommen wurde.The suction device is located in the vacant space between the insertion head / cutting device and the first weft monitor, which space was occupied by the auxiliary warp threads (catch strips) in the prior art.

Erfindungsgemäß entfallen also die Fangleisten.According to the invention, the catch strips are therefore eliminated.

Die Absaugvorrichtung hat die Aufgabe, den von der Streckdüse erfaßten Schußfaden nach erfolgreichem Fadeneintrag zu übernehmen und gespannt zu halten, so daß der Faden von der Schneidevorrichtung geschnitten werden kann. Nach dem Schneiden wird der abgeschnittene Fadenrest durch die Absaugvorrichtung abtransportiert.The suction device has the task of taking over the weft thread caught by the stretching nozzle after successful thread insertion and keeping it tensioned so that the thread can be cut by the cutting device. After cutting, the remaining thread is removed by the suction device.

Vorteil der erfindungsgemäßen Anordnung der Absaugvorrichtung ist, daß gänzlich auf die Verwendung von Hilfskettfäden (Fangleisten) verzichtet werden kann und dadurch eine Material- und Kostenersparnis erreicht wird.An advantage of the arrangement of the suction device according to the invention is that the use of auxiliary warp threads (catch strips) can be dispensed with entirely, thereby saving material and costs.

Weiterhin ist vorteilhaft, daß die Absaugvorrichtung in dem durch das Weglassen der Fangleisten frei gewordenen Raum angeordnet ist, so daß es nicht notwendig ist, aus Platzgründen auf andere wichtige Komponenten zu verzichten.It is also advantageous that the suction device is arranged in the space made free by the omission of the catch strips, so that it is not necessary to dispense with other important components for reasons of space.

Nach dem Stand der Technik war es notwendig, den Breithalter an die gewünschte Gewebebreite anzupassen. Bei der neuen Konstruktion ist vorteilhaft, daß keine Anpassung des Breithalters auf die Gewebebreite vorgenommen werden muß, da die Verwendung von Hilfskettfäden entfällt.According to the prior art, it was necessary to adapt the spreader to the desired fabric width. The advantage of the new design is that the spreader does not have to be adjusted to the width of the fabric, since the use of auxiliary warp threads is eliminated.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

Alle in den Unterlagen, einschließlich der Zusammenfassung, offenbarten Angaben und Merkmale, insbesondere die in den Zeichnungen dargestellte räumliche Ausbildung werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All of the information and features disclosed in the documents, including the summary, in particular the spatial design shown in the drawings are claimed to be essential to the invention, insofar as they are new to the prior art, individually or in combination.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile der Erfindung hervor.The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. Here, from the drawings and their description, further features and advantages of the invention that are essential to the invention emerge.

Figur 1 zeigt das Webblatt 1, in welchem eine Vielzahl von Kettfäden 15 laufen. An das Webblatt 1 schließt sich in der hinteren Position des Webblattes 1 das feststehende Füllstück 2 an, welches die Aufgabe hat, den Schußkanal des Webblattes 1 zu verlängern und einen erfolgreichen Schußeintrag zu gewährleisten. Auf Höhe des Füllstückes 2 ist in Anschlagposition des Webblattes 1 eine Einlegevorrichtung 3 angeordnet. Es schließt sich ein erster Schußfadenwächter 4 an, welcher auf einem Schußwächterhalter 5 angeordnet ist. Daran anschließend folgt die Streckdüse 6, die über einen Kanal 14 verfügt, wobei am Ende dieses Kanals ein zweiter Schußfadenwächter 7 angeordnet ist.FIG. 1 shows the reed 1, in which a large number of warp threads 15 run. In the rear position of the reed 1, the fixed filler 2 adjoins the reed 1, which has the task of lengthening the weft channel of the reed 1 and ensuring a successful weft insertion. At the level of the filler piece 2, an insertion device 3 is arranged in the stop position of the reed 1. A first weft monitor 4 follows, which is arranged on a weft monitor holder 5. This is followed by the stretching nozzle 6, which has a channel 14, a second weft monitor 7 being arranged at the end of this channel.

Zwischen Einlegevorrichtung 3 und erstem Schußfadenwächter 4 ist nun erfindungsgemäß eine Absaugvorrichtung 8 mit einer Saugöffnung 8a angeordnet, welche mit einer Vakuumpumpe 9 arbeitet. Für abgesaugte Fadenreste ist ein Sammelbehälter 10 vorgesehen.Between the insertion device 3 and the first weft monitor 4, a suction device 8 with a suction opening 8a is now arranged according to the invention, which works with a vacuum pump 9. A collecting container 10 is provided for sucked-off thread remnants.

Die Funktionsweise der erfindungsgemäßen Schußfadenhandhabung ist am besten in Verbindung aus den Figuren 2 und 3 ersichtlich.The mode of operation of the weft thread handling according to the invention can best be seen in connection with FIGS. 2 and 3.

Man erkennt in Figur 1eine Eintragsdüse 12, welche den Schußfaden 16 in den Schußkanal des Webblattes 1 und damit in das Webfach 19 einbringt. Mit Hilfe von Hilfsdüsen 13 wird der Schußfaden 16 im Schußkanal 1a geführt. Im Füllstück 2 ist der Schußkanal 1a fortgeführt, so daß der vordere Abschnitt des Fadens in den Bereich des Füllstücks 2 bis hin zum ersten Schußfadenwächter 4 gelangt, wobei die Streckdüse 6 in Aktion tritt, die den vorderen Abschnitt des Fadens erfaßt und den Faden gespannt hält.One can see in FIG. 1 an insertion nozzle 12 which introduces the weft thread 16 into the weft channel of the reed 1 and thus into the shed 19. With the help of auxiliary nozzles 13, the weft thread 16 is guided in the weft channel 1a. In the filler 2, the weft channel 1a is continued, so that the front section of the thread reaches the area of the filler 2 up to the first weft guard 4, the stretching nozzle 6 taking action, which detects the front section of the thread and keeps the thread taut .

Wie aus Figur 3 ersichtlich, verfährt nun das Webblatt 1 mit den notwendigen Vorrichtungen aus der hinteren Position nach vorne, um den Schußfaden 16 an das Gewebe anzuschlagen.As can be seen from FIG. 3, the reed 1 now moves with the necessary ones Devices forward from the rear position to strike the weft 16 against the fabric.

Der vordere Abschnitt des Schußfadens 16 ist also in der Streckdüse 6 gehalten und gespannt. Es wird nun die erfindungsgemäße Absaugvorrichtung 8 aktiviert, wobei gleichzeitig die Streckdüse 6 deaktiviert wird, so daß der Schußfaden von der Streckdüse 6 an die Absaugvorrichtung 8 übergeben wird und durch diese unter Spannung gehalten wird.The front section of the weft thread 16 is thus held and stretched in the stretching nozzle 6. The suction device 8 according to the invention is now activated, the drawing nozzle 6 being deactivated at the same time, so that the weft thread is transferred from the drawing nozzle 6 to the suction device 8 and is held under tension by the latter.

Durch eine Schneidevorrichtung 11 kann zumindest ein Teil des vorderen Schußfadenabschnittes abgeschnitten werden. Der abgeschnittene Teil des Fadenabschnittes verbleibt in der Absaugvorrichtung und wird durch diese in den Sammelbehälter 10 abtransportiert.At least part of the front weft section can be cut off by a cutting device 11. The cut-off part of the thread section remains in the suction device and is transported through it into the collecting container 10.

Der am Gewebe 21 überstehende Fadenrest kann durch eine an sich bekannte Einlegevorrichtung 3 am Geweberand in ein nach dem Schußfadenanschlag gebildetes Webfach eingelegt bzw. zurückgeführt werden.The remaining thread on the fabric 21 can be inserted or returned by a known insertion device 3 on the fabric edge into a shed formed after the weft stop.
