Description

Gegenstand der Erfindung ist eine Webmaschine nach dem Oberbegriff des Anspruches 1.The invention relates to a loom according to the preamble of Claim 1.

Bei den bisher bekannten Webmaschinen (US-A-4 957 144) war es relativ schwierig, von einer Webbreite des Gewebes zur nächsten zu wechseln. Hierzu mußte jeweils die vorgesehene Breithalteeinrichtung mit den zugehörigen Anbauten ausgetauscht werden, danach mußten die beiden gewebeseitigen Einlege- und Schneidvorrichtungen neu montiert und justiert werden. Insgesamt handelt es sich hierbei um eine relativ komplizierte und zeitaufwendige Prozedur.In the previously known weaving machines (US-A-4 957 144) it was relatively difficult to get one Switch the weaving width of the fabric to the next. To do this, the The intended spreader device is replaced with the associated attachments then the two fabric-side insertion and cutting devices had to be can be reassembled and adjusted. Overall, this is a relatively complicated and time-consuming procedure.

Aufgabe der vorliegenden Erfindung ist es daher, auf einfache Weise an einer Webmaschine die Schneid- und Einlegevorrichtung auf unterschiedliche Webbreiten einstellbar zu gestalten, ohne dabei einen ersten Breithaltertisch mit Breithalteeinrichtung gegen einen auf die veränderte Webbreite zugeschnittenen Breithaltertisch mit Breithalteeinrichtung austauschen zu müssen.The object of the present invention is therefore, in a simple manner on a Weaving machine the cutting and inserting device on different weaving widths adjustable, without having a first spreader table Spreading device against one tailored to the changed weaving width Need to replace the spreader table with the spreader device.

Erfindungsgemäß erfolgt diese Lösung durch die Merkmale des kennzeichnenden Teils der Ansprüche 1 und 3.According to the invention, this solution is provided by the features of the characteristic Part of claims 1 and 3.

Dabei ist wesentlich, daß die Schneidvorrichtung mit dem zugehörigen Einleger über die Breite der Webmaschine längs des durchgehend ausgebildeten Breithaltertisches bzw. der durchgehenden StabBreithalteeinrichtung verstellbar ausgebildet ist.It is essential that the cutting device with the associated insert across the width of the loom along the continuously trained Spreader table or the continuous rod-spreading device adjustable is trained.

Mit den erfindungsgemäßen Merkmalen ergibt sich der wesentliche Vorteil, daß beim Wechsel von einer Webbreite zur anderen nunmehr kein Wechsel der Breithalteeinrichtung einschließlich des Breithaltertisches erforderlich ist, sondern einfach die Schneidvorrichtung mit dem zugehörigen Einleger über die Breite der Webmaschine verschoben werden kann. Eine Demontage des Breithaltertisches mit Breithalteeinrichtung ist nicht mehr erforderlich.
Dies ist erfindungsgemäß sowohl bei Luft- als auch bei Greiferwebmaschinen möglich, wenn es sich bei dem Einleger z.B. um eine pneumatisch betriebene Einrichtung handelt.With the features according to the invention there is the essential advantage that when changing from one weaving width to another no change of the spreading device including the spreading table is now required, but rather the cutting device with the associated insert can be moved across the width of the weaving machine. Disassembly of the spreader table with spreader is no longer necessary.
According to the invention, this is possible both in the case of air and rapier weaving machines if the insert is, for example, a pneumatically operated device.

Es ist nun vorgesehen, den verstellbar ausgebildeten Einleger und die Schneidvorrichtung auf einem gemeinsamen Träger anzuordnen. Hierdurch ergibt sich der Vorteil, daß lediglich eine einzige Verstellung erforderlich ist, weil die gegenseitige Lage des Einlegers zur Schneidvorrichtung durch die Halterung auf den gemeinsamen Träger konstant bleibt.It is now provided for the adjustable insert and the Arrange the cutting device on a common support. This gives the advantage that only a single adjustment is required because the mutual position of the insert to the cutting device through the holder the common carrier remains constant.

In einer anderen Ausführungsform der Erfindung ist vorgesehen, den Einleger und die Schneidvorrichtung unabhängig voneinander und verstellbar anzuordnen. Hierdurch ergibt sich der Vorteil, daß die Einlegetiefe im Gewebe leicht einstellbar ist.In another embodiment of the invention, the insert and to arrange the cutting device independently of one another and adjustable. This has the advantage that the insertion depth in the tissue is easily adjustable is.

Beiden Ausführungsformen ist gemeinsam, daß sowohl eine Grobeinstellung auf die ungefähre Breite des Gewebes, als auch eine Feinjustierung von Einleger zur Schneidvorrichtung vorgesehen ist. Durch diese Ausführungsform läßt sich eine genaue Positionierung von Schneidvorrichtung und Einleger zu der zu bildenden Einlegekante im Gewebe in kurzer Zeit erreichen.Both embodiments have in common that both a rough adjustment to the approximate width of the fabric, as well as a fine adjustment of insert for Cutting device is provided. This embodiment allows one exact positioning of the cutting device and insert to the one to be formed Reach the insert edge in the fabric in a short time.

In einer Weiterbildung der obigen Ausführungsformen ist vorgesehen, daß der Einleger an einer feststehenden Klinge der Schneidvorrichtung starr befestigt ist. Die bewegliche Klinge, die vom zugehörigen Motor der Schneidvorrichtung angetrieben ist, ist dann gelenkig an der feststehenden Klinge gelagert. Es ist selbstverständlich auch möglich, nicht nur eine einzige Gewebebahn auf einer Webmaschine zu fertigen, sondern, bei einer genügenden Breite der Webmaschine, mehrere Gewebebahnen nebeneinander herzustellen.In a development of the above embodiments it is provided that the Insert is rigidly attached to a fixed blade of the cutting device. The movable blade, which is associated with the cutter's motor is driven, is then articulated on the fixed blade. Of course, it is also possible not just a single web of fabric on one Manufacture loom, but, with a sufficient width of the loom, to produce several fabric webs next to each other.

Für die Ausbildung des Breithaltertisches selbst gibt es mehrere Möglichkeiten. In einer ersten Ausführungsform ist der Breithaltertisch mit einem zwischen dem Breithaltertisch und dem Breithalterdeckel angeordneten im wesentlichen zylinderförmigen Breithalterstab vorgesehen. Breithalterdeckel und -stab bilden die Breithalteeinrichtung. In einer zweiten Ausführungsform ist vorgesehen, einen sogenannten Nadelbreithalter einzusetzen, der im wesentlichen zwischen zwei am Breithaltertisch befestigten Ausbreitelementen in das fertige Gewebe eingreift. There are several options for designing the spreader table itself. In a first embodiment is the spreader table with a between the Spreader table and the spreader cover arranged essentially cylindrical Spreader bar provided. Spreader cover and rod form the Spreading device. In a second embodiment, one is provided use so-called needle spreader, which is essentially between two am Spreading table attached spreading elements engages in the finished fabric.

Zur Minimierung der Webblattmasse ist vorgesehen, das feststehende Hilfswebblatt direkt mit dem Träger des Einlegers zu verbinden. Hierdurch wird der Justieraufwand bei einer Breitenverstellung weiter vermindert.The fixed auxiliary reed is provided to minimize the reed mass to be connected directly to the carrier of the insert. This will Adjustment effort with a width adjustment further reduced.

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 Vorteil der Erfindung hervor.In the following, the invention is explained using only one embodiment illustrative drawings explained in more detail. Here go from the drawings and its description further features and advantages of the invention Invention.

Die Fig. 1 und 2 zeigen jeweils eine identische Seitenansicht in zwei unterschiedlichen Ausführungsformen der Breithalteeinrichtung. Hierbei werden gleiche Bauteile mit gleichen Bezugszeichen versehen.1 and 2 each show an identical side view in two different embodiments of the spreading device. Here are Identical components with the same reference numerals.

Gemäß diesen Figuren werden von einem nicht näher dargestellten Kettbaum Kettfäden 1 zugeführt, die über die jeweiligen Webschäfte 2 in den Pfeilrichtungen 3, 4 beweglich sind. Diese Kettfäden 1 bilden das im wesentlichen dreieckige Webfach 5 aus.According to these figures, a warp beam (not shown) Warp threads 1 fed over the respective heald frames 2 in the arrow directions 3, 4 are movable. These warp threads 1 form the essentially triangular Shed 5 out.

In dieses Webfach wird senkrecht zur Zeichenebene in Fig. 1 und Fig. 2 ein nicht näher dargestellter Schußfaden eingetragen, wobei dieser Eintrag entweder mittels Luftstrom durch Düsen oder durch Greifer erfolgen kann. Im dargestellten Ausführungsbeispiel erfolgt der Eintrag des Schußfadens mittels einer Düse 29. In this shed a perpendicular to the plane of the drawing in Fig. 1 and Fig. 2 is not weft thread shown, this entry either using Air flow can take place through nozzles or through grippers. In the illustrated In the exemplary embodiment, the weft thread is inserted by means of a nozzle 29.

Der Schußfadeneintrag erfolgt, wenn sich das schwenkbar angeordnete Webblatt 6 in seiner zurückgezogenen Stellung befindet. Danach wird das Webblatt 6 nach vorne in Pfeilrichtung 7 geschwenkt und schlägt somit den Schußfaden am Bindepunkt 9a des Gewebes 9 an. Während das Webblatt 6 in seine Ausgangsposition in Pfeilrichtung 8 zurückschwenkt und mittels der Webschäfte 2 ein Fachwechsel erfolgt, wird über die Schneidvorrichtung 23 der Schußfaden abgetrennt und mittels des Einlegers 14 in ein folgendes gebildetes Webfach 5 eingelegt.The weft thread is inserted when the pivotably arranged reed 6 is in its retracted position. Then the reed 6 is after pivoted at the front in the direction of arrow 7 and thus beats the weft thread at the binding point 9a of the fabric 9. While the reed 6 in its starting position in Arrow direction 8 swings back and by means of the heald frames 2 a change of subject takes place, the weft is cut off by means of the cutting device 23 and by means of of the insert 14 is inserted into a subsequent shed 5.

Das fertiggestellte Gewebe 9 wird gemäß Fig. 1 über den Breithaltertisch 11, den Breithalterstab 10 und den Breithalterdekkel 12 abgezogen. Der Breithalterdeckel 12 ist über eine Stütze 12a mit einem maschinenfesten Bauteil 13 verbunden.The finished fabric 9 is shown in FIG. 1 on the spreader table 11 Spreader bar 10 and the spreader cap 12 are removed. The spreader lid 12 is connected to a machine-fixed component 13 via a support 12a.

Es wird aus Gründen einer massearmen Ausbildung des Webblattes 6 bevorzugt, wenn das Hilfswebblatt 6a starr am Einlegerträger 25 befestigt ist. Der Einleger selbst ist z.B. über den Träger 25 direkt mit dem Bauteil 13 in eine Führung 13b verstellbar verbunden.For reasons of low-mass formation of the reed 6, it is preferred when the auxiliary reed 6a is rigidly attached to the insert carrier 25. The depositor itself is e.g. via the carrier 25 directly with the component 13 in a guide 13b adjustable connected.

Die Schneidvorrichtung 23 besteht im wesentlichen aus einem Antriebsmotor 20, der mit einem Arm 18 versehen ist, an welchem ein Arm 19 angelenkt ist, und der Arm 18 zum Zwecke des Schußfadenschneidens zwischen zwei Anschlägen 21, 22 hin- und herpendelt. Der Arm 19 ist mit der beweglichen Klinge 16 der Schneidvorrichtung 23 verbunden, die wiederum mit einem Gelenk 17 mit der feststehenden Klinge 15 verbunden ist. Im gezeigten Ausführungsbeispiel kann diese feststehende Klinge 15 starr mit dem Einleger 14 bzw. dessen Träger 25 verbunden sein.The cutting device 23 consists essentially of a drive motor 20 which is provided with an arm 18, on which an arm 19 is articulated, and the arm 18 for the purpose of weft cutting between two stops 21, 22 and shuttles. The arm 19 is with the movable blade 16 Cutting device 23 connected, which in turn with a joint 17 with the fixed blade 15 is connected. In the embodiment shown this fixed blade 15 rigidly with the insert 14 or its support 25 be connected.

Die gesamte Schneidvorrichtung 23 ist mittels eines Trägers 24 in Analogie zum Einleger in einer Führung 13a in dem Bauteil 13, das die Breithalteeinrichtung 11, 12 trägt, geführt und befestigt.The entire cutting device 23 is by means of a carrier 24 in analogy to Insert in a guide 13a in the component 13, which the spreading device 11, 12 carries, guided and attached.

In einer weiteren dargestellten Ausführungsform ist es ebenfalls möglich, den Einleger 14 und die Schneidvorrichtung 23 über einen Verbundträger, bestehend aus den Trägern 24, 25, auf dem gemeinsamen maschinenfesten Bauteil 13 zu führen und zu befestigen. In a further illustrated embodiment, it is also possible to use the Insert 14 and the cutting device 23 via a composite carrier from the carriers 24, 25 on the common machine-fixed component 13 lead and fasten.

Der Unterschied zwischen Fig. 1 und Fig. 2 besteht darin, daß gem. Fig. 2 nicht mehr ein Breithaltertisch 11 in Verbindung mit einem Breithalterstab 10 und einem Breithalterdeckel 12 vorgesehen ist, sondern anstelle des Breithalterstabes 10 und des Breithalterdeckels 12 ein Nadelbreithalter 26 verwendet wird. Hier wird die fertiggestellte Gewebebahn 9 über zwei am Breithaltertisch 11 angebrachte Ausbreitwalzen oder Ausbreitrollen 11a bzw. 11b geführt, wobei zwischen diesen Rollen der Nadelbreithalter 26 das Gewebe 9 führt.The difference between Fig. 1 and Fig. 2 is that according to. Fig. 2 does not more a spreader table 11 in connection with a spreader bar 10 and one Spreader cover 12 is provided, but instead of the spreader rod 10 and the spreader cover 12 a needle spreader 26 is used. Here is the completed fabric web 9 over two attached to the spreader table 11 Spreading rollers or spreading rollers 11a and 11b guided, between them Rolling the needle spreader 26 leads the tissue 9.

Fig. 3 zeigt eine schematische Draufsicht auf die erfindungsgem. Ausbildung an der Webmaschine. Hierbei ist an der linken Seite eine Schußfadeneintragseinrichtung 29 vorgesehen, die, wie bereits gesagt, z.B. in Form einer Schußfadeneintragsdüse oder als Greifer ausgebildet sein kann. Beim Schußfadeneintrag quert der Schußfaden das feststehende Hilfswebblatt 6a, gelangt nachfolgend in das sich in seiner hinteren Anschlagposition befindende schwenkbare Webblatt 6 und durchquert sodann das rechte, feststehende Hilfswebblatt 6b.
In dieser Figur sind die Schneidvorrichtungen 23, 23a nur schematisch durch stilisierte Scheren dargestellt.
Um nun die kombinierte Schneid- und Einlegervorrichtung auf eine veränderte Webbreite einstellen zu können, ist vorgesehen, den rechten Einleger 14a sowie die zugehörige Schneidvorrichtung 23a in den Pfeilrichtungen 27, 28 verschiebbar auszubilden. Es wird hierbei bevorzugt, wenn, wie bereits erwähnt, das feststehende Hilfswebblatt 6b am Träger 25 des Einlegers 14a oder an einem geeigneten Anbauteil des Einlegers 14a befestigt ist, wie in den Fig. 1 und 2 gezeigt.Fig. 3 shows a schematic plan view of the invention. Training on the weaving machine. Here, a weft insertion device 29 is provided on the left side, which, as already mentioned, can be designed, for example, in the form of a weft insertion nozzle or as a gripper. When the weft thread is inserted, the weft thread crosses the fixed auxiliary weaving reed 6a, subsequently passes into the pivotable weaving reed 6 located in its rear stop position and then traverses the right, fixed auxiliary weaving reed 6b.
In this figure, the cutting devices 23, 23a are shown only schematically by stylized scissors.
In order to be able to adjust the combined cutting and inserting device to a changed weaving width, provision is made for the right insert 14a and the associated cutting device 23a to be displaceable in the arrow directions 27, 28. It is preferred in this case if, as already mentioned, the fixed auxiliary reed 6b is attached to the carrier 25 of the insert 14a or to a suitable attachment part of the insert 14a, as shown in FIGS. 1 and 2.

Fig. 4 zeigt eine weitere Ausführungsform, bei der zwei Gewebebahnen 9, 9a gleichzeitig auf der Webmaschine hergestellt werden.
Hierbei ist vorgesehen, daß zwischen den Gewebebahnen lediglich eine einzige Schneidvorrichtung 23b angeordnet ist, die für die zugehörigen Einleger 14b, 14c die Schußfadenenden bereitstellt.4 shows a further embodiment in which two fabric webs 9, 9a are produced simultaneously on the weaving machine.
It is provided here that only a single cutting device 23b is arranged between the fabric webs, which provides the weft thread ends for the associated inserts 14b, 14c.

Vorteilhaft bei der in Fig. 4 gezeigten Ausgestaltung ist, daß für den jeweils rechten Geweberand der selbe Einleger verwendet werden kann. Für den linken Geweberand wird ebenfalls jeweils der selbe Einleger verwendet.
Die Einleger 14 und 14c sind identisch und die Einleger 14a und 14b sind identisch. Es ist nun möglich, den rechten Einleger 14a sowie die beiden mittigen Einleger 14b, 14c in Pfeilrichtung 27, 28 gegeneinander sowie über die gesamte Webbreite der Webmaschine zu verstellen.An advantage of the embodiment shown in FIG. 4 is that the same insert can be used for the right fabric edge. The same insert is also used for the left edge of the fabric.
The inserts 14 and 14c are identical and the inserts 14a and 14b are identical. It is now possible to adjust the right-hand insert 14a and the two central inserts 14b, 14c in the direction of arrow 27, 28 against each other and over the entire weaving width of the weaving machine.

Wie bereits eingangs erwähnt, ist für jeden Einleger 14, 14a, 14b, 14c sowie für jede Schneidvorrichtung 23, 23a, 23b eine Grob- sowie eine Feinjustierung vorgesehen, die in x-, y- und z-Richtung erfolgen kann. Die Grobjustierung erfolgt hierbei bevorzugt dadurch, daß der jeweilige Träger 24, 25 oder der daraus gebildete Verbundträger in entsprechenden Führungen 13a, 13b, 13c des Bauteils 13 verstellbar ist.As already mentioned at the beginning, 14, 14a, 14b, 14c as well as for each is for each insert Cutting device 23, 23a, 23b a coarse and a fine adjustment provided, which can be done in the x, y and z directions. The rough adjustment is done here preferably in that the respective carrier 24, 25 or the one formed therefrom Composite carrier in corresponding guides 13a, 13b, 13c of component 13 is adjustable.

Mit der erfindungsgemäßen Lösung wurde somit eine Möglichkeit geschaffen, unter Vermeidung eines komplexen Justierungs- und Einrichtungsaufwandes und ohne dem Wechsel des Breithaltertisches mit Breithalteeinrichtung an Gewebebahnen unterschiedlicher Breite, Einlegekanten exakt auszubilden. With the solution according to the invention, a possibility was thus created under Avoiding complex adjustment and setup effort and without changing the spreader table with spreader on fabric webs of different widths to form insert edges exactly.
