Abstract
Description
Die Erfindung betrifft eine Anordnung zum Direktfachen an Luftdüsen-Webmaschinen mit mehreren parallelen Kreuzspulen als Garnvorrat.The invention relates to an arrangement for direct shedding on air-jet weaving machines with a plurality of parallel packages as a yarn supply.
Mit der Anordnung nach der Erfindung werden an einer Luftdüsen-Webmaschine mehrfach gefachte Garne und/oder Zwirne hergestellt.With the arrangement according to the invention, multiple-fold yarns and / or threads are produced on an air-jet weaving machine.
Bisher war es bekannt, wenn man in einer Luftdüsen-Webmaschine ein mehrfach gefachtes Garn oder Zwirn verwenden wollte, daß man die Herstellung der Fachung des Garnes oder Zwirns in einer vorgeschalteten Fachmaschine durchführte. Dies war mit einem erhöhten Maschinenaufwand verbunden, was zu höheren Herstellungskosten führte und zu einer Verkomplizierung der Arbeitsgänge, weil in bekannter Weise vorher der Arbeitsgang der Fachung des Garnes vorgeschaltet werden mußte.Up to now it was known, if one wanted to use a multiple-fold yarn or twine in an air-jet weaving machine, that the manufacture of the shed of the yarn or twine was carried out in an upstream specialist machine. This was associated with an increased outlay on machinery, which led to higher production costs and to a complication of the work steps, because the work step had to be preceded by the shedding of the yarn in a known manner.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine Luftdüsen-Webmaschine der eingangs genannten Art so weiterzubilden, daß die Verarbeitung eines mehrfach gefachten Garnes vereinfacht wird.The present invention has for its object to develop an air jet loom of the type mentioned that the processing of a multi-fold yarn is simplified.
Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Herstellung des gefachten Garnes auf der Luftdüsen-Webmaschine selbst direkt erfolgt.To achieve the object, the invention is characterized in that the production of the plied yarn is carried out directly on the air jet loom.
In einer bevorzugten Ausführungsform der vorliegenden Erfindung ist vorgesehen, daß eine Anzahl von Garne und/oder Zwirne von einem Garnvorrat abgezogen werden und einem einzigen Schußfadenspeicher zugeführt werden.In a preferred embodiment of the present invention it is provided that a number of yarns and / or threads are drawn off from a yarn supply and fed to a single weft store.
Von dem Garnvorrat kann sowohl ein Garn ( ein einfädiges,textiles Gebilde bestehend aus Spinnfasern oder Filamenten) oder auch ein Zwirn entnommen werden, wobei unter dem Begriff Zwirn die durch zusammendrehen (zwirnen) einfacher Garne entstehenden Zwirne verstanden werden.Both a yarn (a single-thread, textile structure consisting of staple fibers or filaments) or a twine can be taken from the yarn supply, the term twine being understood to mean the twists formed by twisting (twisting) simple yarns.
Diese Garne oder Zwirne werden also parallel von parallel zueinander angeordneten Kreuzspulen oder Garnvorräten abgezogen. Um einen Bruch dieser Garne oder Zwirne festzustellen ist vorteilhaft ein Fadenführer mit integrierten Wächtern vorgesehen, wobei dieser Fadenführer bevorzugt zwischen der Kreuzspule oder dem Garnvorrat und dem Schußfadenspeicher geschaltet ist.These yarns or threads are thus drawn off in parallel from cross-wound bobbins or yarn stores arranged parallel to one another. In order to determine a break in these yarns or threads, a thread guide with integrated monitors is advantageously provided, this thread guide preferably being connected between the package or the thread supply and the weft thread store.
Der Schußfadenspeicher ist ein bekanntes Element und besteht im wesentlichen aus einem rechtwinklig abgekröpften Fadenführungselement, welches den an der Eingangsseite hereinkommenden Faden auf einen feststehenden Trommelspeicher aufwickelt. Der Trommelspeicher mündet ausgangsseitig in eine Mündung, an der unmittelbar die Schußeintragselemente der Luftdüsen-Webmaschine ansetzen. Dieser Schußfadenspeicher hat im übrigen die Aufgabe eine genau abgemessene Fadenlänge der Luftdüsen-Webmaschine zur Verfügung zu stellen.The weft thread store is a known element and essentially consists of a right-angled thread guide element which winds the thread coming in on the input side onto a fixed drum store. On the output side, the drum store opens into a mouth at which the weft insertion elements of the air-jet weaving machine directly attach. This weft store has the task of providing a precisely measured thread length of the air jet loom.
Dieses am Ausgang des Schußfadenspeichers abgezogene Garn wird dann den Schußeintragsorganen der Luftdüsen-Webmaschine zugeführt, wie z. B. der Hauptdüse.This drawn off at the exit of the weft store yarn is then fed to the weft insertion organs of the air jet loom, such as. B. the main nozzle.
Im Sinne der vorstehenden Beschreibung kommt also am Ausgang des Schußfadenspeichers ein mehrfach gefachtes Garn ( kein Zwirn!) heraus, weil ein Zwirn nur dann vorläge, wenn der Faden einen bestimmten Drall hätte, was hier nicht der Fall ist.In the sense of the above description, a multi-fold yarn (no twist!) Comes out at the exit of the weft store, because a twist would only exist if the yarn had a certain twist, which is not the case here.
Der Schußfadenspeicher übernimmt also die an seinem Eingang getrennt zugeführten Garne und Zwirne einfach in paralleler Form, d. h. diese Garne und Zwirne werden im Schußfadenspeicher in zueinander parallele Form gebracht, so daß am Ausgang des Schußfadenspeichers das mehrfach gefachte Garn vorliegt, ohne Zwirnung.The weft store therefore takes over separately at its entrance supplied yarns and twists simply in parallel form, ie these yarns and twists are brought into parallel form in the weft store, so that the multiply folded yarn is present at the exit of the weft store without twisting.
In einer Weiterbildung der vorliegenden Erfindung ist die Vervielfachung der erfindungsgemäßen Anordnung vorgesehen, wobei nicht nur ein Schußfadenspeicher vorhanden ist sondern eine Vielzahl von Schußfadenspeichern und jedem Schußfadenspeicher nun über eine entsprechende Anzahl von Kreuzspulen oder Garnvorräten eine Anzahl von Garnen oder Zwirnen zugeführt wird.In a further development of the present invention, the arrangement according to the invention is multiplied, not only a weft store but also a plurality of weft stores and each weft store now being supplied with a number of yarns or twists via a corresponding number of cross-wound bobbins or yarn stores.
Am Eingang der Luftdüsen-Webmaschine wird dann nicht nur ein mehrfach gefachtes Garn eingetragen, sondern über eine entsprechend vervielfachte Hauptdüse auch zwei, drei oder vier mehrfach gefachte Garne.At the entrance to the air jet weaving machine, not only is a yarn that has been multiplied several times entered, but also two, three or four yarns that have been multiplied several times via a correspondingly multiplied main nozzle.
Wichtig ist hierbei, daß der Fadenführer mit dem integrierten Bruchwächter zwischen der Kreuzspule oder dem Garnvorrat und dem Schußfadenspeicher angeordnet ist, denn nur so könnte ein Schußfadenbruch eines einzelnen Garnes oder Zwirnes festgestellt werden.It is important here that the thread guide with the integrated break monitor is arranged between the package or the yarn supply and the weft store, because only in this way could a weft break of an individual yarn or thread be determined.
Die Anordnung eines Wächters am Ausgang des Schußfadenspeichers hätte keinen Sinne mehr, denn man könnte durch diesen Wächter nicht mehr feststellen, ob am Eingang des Schußfadenspeichers ein oder mehrere Garne oder Zwirne fehlen.The arrangement of a guard at the exit of the weft store would no longer make sense, because one could no longer determine by this guard whether one or more yarns or twists are missing at the entrance of the weft store.
Die Erfindung wird nun anhand eines Ausführungsbeispieles näher erläutert.The invention will now be explained in more detail using an exemplary embodiment.
In der Zeichnung ist mit 1 eine Luftdüsen-Webmaschine, mit 2 ein Schußfadenspeicher, mit 3 das am Ausgang des Schußfadenspeichers durch den Schußfadenspeicher erzeugte mehrfach gefachte Garn mit 4 das einfach Garn oder der Zwirn, welches von der Kreuzspule oder dem Garnvorrat 6 jeweils getrennt abgezogen wird und mit 5 der Fadenführer mit integriertem Bruchwächter, wobei wichtig ist, daß jedem einfach Garn oder Zwirn 4 jeweils ein Fadenführer mit integriertem Wächter zugeordnet ist.In the drawing, 1 is an air-jet weaving machine, 2 is a weft store, and 3 is the one at the exit of the weft store the weft store produced multiple fold yarn with 4 the single yarn or thread, which is drawn off separately from the package or yarn supply 6 and with 5 the thread guide with integrated break monitor, it being important that each single thread or thread 4 has a thread guide is assigned with an integrated guard.
Bei Bruch des einfach Garns oder des Zwirns 4 wird dann die Luftdüsen-Webmaschine über die gezeigten Signalleitungen 7 sofort außer Betrieb gesetzt.If the simple yarn or the twine 4 breaks, the air jet weaving machine is immediately put out of operation via the signal lines 7 shown.
In der Abbildung ist nicht näher dargestellt, daß dem Schußfadenspeicher 2 eine Anordnung zur Abmessung der Länge des mehrfach gefachten Garnes zugeordnet ist, so daß über diese Anordnung eine ganz bestimmte Länge immer in die Luftdüsen-Webmaschine eingetragen wird.The figure does not show in more detail that an arrangement for measuring the length of the multiple-fold yarn is assigned to the weft store 2, so that a specific length is always entered into the air-jet weaving machine via this arrangement.
Mit der beschriebenen Anordnung zum Direktfachen von mehrfach gefachten Garnen wird also der wesentliche Vorteil erzielt, daß eine der Luftdüsen-Webmaschine vorgeschaltete und getrennt von der Luftdüsen-Webmaschine arbeitende Facheinrichtung vermieden wird, d. h. es wird ein wesentlicher Apparateaufwand eingespart, es werden wesentliche Fehlerquellen vermieden und erfindungsgemäß wird die Anordnung jetzt wesentlich vereinfacht, denn durch die Anordnung zum Direktfachen sind direkt zwischen den Kreuzspulen oder dem Garnvorrat und dem Schußfadenspeicher die Bruchwächter angeordnet, so daß stets das Garn auf Vollständigkeit abgeprüft wird.With the arrangement described for the direct shedding of multiply folded yarns, the essential advantage is achieved that a shed device upstream of the air jet loom and working separately from the air jet loom is avoided, i. H. it saves a considerable amount of apparatus, essential sources of error are avoided and the arrangement is now simplified considerably according to the invention, because the arrangement for direct shedding means that the breakage monitors are arranged directly between the packages or the thread supply and the weft store, so that the thread is always checked for completeness becomes.
Die Anordnung ist damit auch wesentlich flexibler als im Vergleich zu vorgeschalteten Fachmaschinen, denn bei derartigen Fachmaschinen bedarf es zunächst der Herstellung großer Chargen, damit diese Vorrichtungen überhaupt wirtschaftlich arbeiten, dann bedarf es noch der Übertragung der hergestellten mehrfach gefachten Garne auf die Luftdüsen-Webmaschine und dies wird alles gemäß der vorliegenden Erfindung vermieden.The arrangement is thus also considerably more flexible than in comparison to upstream specialist machines, because such specialist machines first require the production of large batches, so that these devices work economically at all, then transmission is still required of the multi-ply yarns produced on the air jet loom and all of this is avoided in accordance with the present invention.
Weiterer Vorteil dieer Erfindung ist, daß am Ausgang der Fachmaschine ja ein mehrfach gefachtes Garn erzeugt wird, welches aufgrund seines Volumens auf einer großvolumigen Spule aufgewickelt wird, auf der nur eine sehr kurze Garnlänge aufgewickelt werden kann, weil es sich hier ja um ein mehrfach gefachtes Garn handelt.Another advantage of this invention is that a multi-fold yarn is produced at the output of the specialist machine, which due to its volume is wound on a large-volume spool on which only a very short length of yarn can be wound, because this is a multi-fold Yarn deals.
Gemäß der vorliegenden Erfindung werden hier Spulen verwendet auf denen einfach Garn oder Zwirn aufgewickelt ist und daher können auf derartigen Einzelspulen wesentlich größere Längen aufgewickelt werden, so daß der Arbeitsvorgang des Anknüpfens von Garn stark reduziert wird.According to the present invention, bobbins are simply used here on which yarn or twine is wound, and therefore much greater lengths can be wound on such individual bobbins, so that the process of tying yarn is greatly reduced.
