Description

Vorrichtung zum Bilden eines Drehergewebes Device for forming a leno fabric
Die Erfindung betrifft eine Vorrichtung zum Bilden eines Drehergewebes mit einer Vielzahl von nebeneinander angeordneten Nadeln mit jeweils einem Führungsauge für einen Kettfaden und mit eine Vielzahl von nebeneinander angeordnete Führungsaugen für Kettfäden aufweisenden Mitteln, die Kettfäden relativ zu den stationären Nadeln in Längsrichtung der Nadeln und quer dazu bewegen.The invention relates to a device for forming a leno fabric with a plurality of juxtaposed needles, each with a guide eye for a warp thread and with a plurality of juxtaposed guide eyes for warp thread means, the warp threads relative to the stationary needles in the longitudinal direction of the needles and transversely thereto move.
Bei einer bekannten Vorrichtung der eingangs genannten Art nach der DE 466 340 dient als parallel und quer zu den Nadeln bewegliches Element ein Schaftrahmen mit zwei gegensinnig bewegbaren Lochschienen, die innerhalb eines Schaftrahmens an Blattfederstäben aufgehängt sind. Bei den Querbewegungen werden diese Blattfedern durchgebogen.In a known device of the type mentioned at the outset according to DE 466 340, a shaft frame with two perforated rails which can be moved in opposite directions and which are suspended from leaf spring bars within a shaft frame serves as the element which can be moved parallel and transversely to the needles. These leaf springs are deflected during the transverse movements.
Es ist auch bekannt, beispielsweise aus CH 579 162, FR 2 174 675 und WO 98/07913, das mit der Vielzahl der Führungsaugen versehene Element und die Nadeln mit den Führungsaugen relativ zu einander zu bewegen. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der hohe Webgeschwindigkeiten erzielbar sind, ohne dass die Gefahr von Fehlern aufgrund von Schwingungen besteht.It is also known, for example from CH 579 162, FR 2 174 675 and WO 98/07913, to move the element provided with the plurality of guide eyes and the needles with the guide eyes relative to one another. The invention has for its object to provide a device of the type mentioned, in which high weaving speeds can be achieved without the risk of errors due to vibrations.
Diese Aufgabe wird dadurch gelöst, dass die sich mit den Führungsaugen bewegenden Mittel sowohl bei in Längsrichtung der Nadeln erfolgenden Längsbewegungen als auch bei quer dazu erfolgende Querbewegungen in Führungen geführt sind.This object is achieved in that the means which move with the guide eyes are guided in guides both in the case of longitudinal movements in the longitudinal direction of the needles and in the case of transverse movements transverse to them.
Damit wird erreicht, dass sowohl die Nadeln als auch das die Vielzahl von Führungsaugen aufweisende Mittel weder in Längsrichtung noch in Querrichtung Schwingungen ausführen, die den Webvorgang beeinträchtigen könnten.It is thereby achieved that both the needles and the means having the plurality of guide eyes do not vibrate either in the longitudinal direction or in the transverse direction, which could impair the weaving process.
Vorteilhaft wird vorgesehen, dass die Nadeln von oben nach unten gerichtet sind und zur Aufnahme der Kettfäden einer die Unterseite eines Webfachs bildenden Kettfadenschar dienen. Dadurch lassen sich die Antriebe, insbesondere für die Auf- und Abbewegung des bewegbaren Elementes unten anordnen, d.h. in einer Position, in der üblicherweise die Antriebe von Webschäften angeordnet sind. Damit ist es möglich, das Element mittels eines einem Antrieb für Webschäfte ähnelnden Antriebs anzutreiben.It is advantageously provided that the needles are directed from top to bottom and serve to receive the warp threads of a warp thread group forming the underside of a shed. As a result, the drives, in particular for the up and down movement of the movable element, can be arranged below, i.e. in a position in which the drives of heald frames are usually arranged. It is thus possible to drive the element by means of a drive similar to a drive for heald frames.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass ein Antrieb mit eigenem Antriebsmotor zum Ausführen der Querbewegungen vorgesehen ist. Dadurch wird die Möglichkeit gegeben, ohne großen Aufwand an Einstellungen einer Maschine die Dreherbindungen zu ändern. Darüber hinaus ist es möglich, mittels eines derartigen Antriebsmotors die Bewegungen des mit der Vielzahl von Führungsaugen versehenen Elementes zu Zeiten durchzuführen, in welchen die darin geführten Kettfäden nicht an den stationär angeordneten Nadeln anliegen. Damit wird die Gefahr der Anregung der Nadeln zu Schwingungen reduziert. Außerdem wird die Gefahr eines Verschleisses der Nadeln vermindert.In a further embodiment of the invention, it is provided that a drive with its own drive motor is provided for executing the transverse movements. This enables the lathe bindings to be changed without much effort in the settings of a machine. In addition, it is possible by means of such a drive motor to carry out the movements of the element provided with the plurality of guide eyes at times when the warp threads guided therein do not rest on the needles arranged in a stationary manner. This eliminates the danger of Excitation of the needles reduced to vibrations. It also reduces the risk of needle wear.
Bei einer vorteilhaften Ausführungsform wird vorgesehen, dass der Antrieb als ein vorzugsweise einstellbarer Exzenterantrieb gestaltet ist. Dadurch ist es möglich, die Relativpositionen der Nadeln und der Führungsaugen des Elementes zueinander einzustellen.In an advantageous embodiment, it is provided that the drive is designed as a preferably adjustable eccentric drive. This makes it possible to adjust the relative positions of the needles and the guide eyes of the element to one another.

Jeweils eine Gruppe von Nadeln 1 ist in einem Halter 2 montiert. Die Halter 2 sind austauschbar hintereinander auf einer Trägerplatte 3 befestigt, die mittels Schrauben 4 an einem Querbalken 5 befestigt ist. Der Querbalken 5 erstreckt sich über die gesamte Breite der Webmaschine und wird mittels Halteböcken 6 am nicht dargestellten Seitenrahmen der Webmaschine angebracht. Die Höhenposition der Nadeln kann mit Hilfe von Einstellschrauben 7 eingestellt werden, die an einer abgewinkelten Kante der Trägerplatte 3 angebracht sind und sich auf dem Querbalken 5 abstützen.

A group of needles 1 is mounted in a holder 2. The holders 2 are interchangeably fastened one behind the other on a carrier plate 3 which is fastened to a crossbar 5 by means of screws 4. The crossbeam 5 extends over the entire width of the weaving machine and is attached to the side frame of the weaving machine (not shown) by means of support brackets 6. The height position of the needles can be adjusted with the aid of adjusting screws 7, which are attached to an angled edge of the carrier plate 3 and are supported on the crossbeam 5. By means of these adjusting screws, the position can be changed in which the carrier plate 3 is fastened to the crossbar 5 by means of the screws 4.
Die Webmaschine ist mit einem weiteren Querbalken 8 versehen, der sich ebenfalls über die gesamte Breite der Webmaschine erstreckt und der an den Seitenrahmen der Webmaschine befestigt ist. Zwischen der Träger- platte 3 und dem zweiten Querbalken 8 sind in regelmäßigen Abständen voneinander Stützen 9 angebracht, um Verformungen der Trägerplatte 3, sowie der Querbalken 5 und 8 zu begrenzen.The weaving machine is provided with a further crossbeam 8, which likewise extends over the entire width of the weaving machine and which is fastened to the side frame of the weaving machine. Between the carrier plate 3 and the second crossbar 8 are at regular intervals from each other supports 9 to limit deformation of the support plate 3, and the crossbars 5 and 8.
In regelmäßigen Abständen sind an der Trägerplatte 3 Halter 10 befestigt, beispielsweise mit nicht dargestellten Schrauben, die durch die Halter 2 hindurch in die Trägerplatte 3 eingeschraubt werden. Auf diesen Haltern 10 liegt eine Umlenkstange 11 , die die Kettfäden umlenkt, die von den Führungsaugen der Nadeln geführt werden. Die Umlenkstange 11 wird mittels eines Klemmhalters 12 in einer definierten Axialposition an der Trägerplatte 3 befestigt.Holders 10 are fastened to the carrier plate 3 at regular intervals, for example with screws, not shown, which are screwed into the carrier plate 3 through the holders 2. On these holders 10 there is a deflecting rod 11 which deflects the warp threads which are guided by the guide eyes of the needles. The deflecting rod 11 is fastened to the carrier plate 3 in a defined axial position by means of a clamp holder 12.
Zusätzlich zu den mit Führungsaugen für Kettfäden versehenen Nadeln 1 ist entsprechend Fig. 1 und 2 ein leistenartiges Element 13 vorgesehen, das eine Vielzahl von Führungsaugen 14 für Kettfäden besitzt. Dieses E- lement 13 erstreckt sich im wesentlichen über die gesamte Breite der Webmaschine. Der Abstand zwischen den Führungsaugen 14 des Elementes 13 entspricht dem Abstand zwischen den Nadeln 1 , d.h. der Führungsaugen der Nadeln 1. Das Element 13 ist fest in einem Rahmen 15 angeordnet, der zwei Seitenteile 16 aufweist, die über das Element 13 und eine einen größeren Querschnitt aufweisende Querstrebe 17 verbunden sind. Die Seitenteile 16 sind in Führungen 18 geführt, so dass der Rahmen 15 in einer Ebene nach oben und unten sowie seitlich hin- und herbewegt werden kann, die im wesentlichen lotrecht zu den Kettfäden gerichtet ist. Bei dem dargestellten Ausführungsbeispiel ist der Rahmen 15 im Bereich der Seitenteile 16 mittels eines Gelenkes 19, Verbindungsstangen 20, 21 und einem Hebel 22 mit einem nicht dargestellten Antrieb für ein Auf- und Abwärtsbewegen des Rahmens 15 verbunden. Die Hebel 22 beider Seiten sind in bekannter Weise auf Querträgern 23 der Webmaschine gelagert. Der Antrieb kann einem üblichen Antrieb für Rahmen von Webschäften entsprechen. Ein solcher Antrieb enthält beispielsweise ein Nockensystem, das den Rahmen 15 zwischen zwei aufeinanderfolgenden Einträgen von Schussfäden aus der obersten Position über die unterste Position wieder zurück in die oberste Position bringen kann. Das Nockensystem kann dabei so gestaltet werden, dass die Aufwärtsbewegung und die Abwärtsbewegung jeweils über eigene Nocken bewirkt werden. Mittels eines derartigen Antriebes kann das Element 13 in einer im wesentlichen lotrecht zu den Kettfäden verlaufenden und von den Führungen 18 bestimmten Ebene in Richtung S nach oben und nach unten bewegt werden.In addition to the needles 1 provided with guide eyes for warp threads, a strip-like element 13 is provided according to FIGS. 1 and 2, which has a plurality of guide eyes 14 for warp threads.

In the exemplary embodiment shown, the frame 15 is connected in the region of the side parts 16 by means of a joint 19, connecting rods 20, 21 and a lever 22 to a drive (not shown) for moving the frame 15 up and down. The levers 22 on both sides are mounted in a known manner on cross members 23 of the weaving machine. The drive can correspond to a conventional drive for frames of heald frames. Such a drive contains, for example, a cam system that separates the frame 15 between two consecutive entries Can bring weft threads from the top position over the bottom position back to the top position. The cam system can be designed so that the upward movement and the downward movement are each effected via their own cams. By means of such a drive, the element 13 can be moved up and down in the direction S in a plane running essentially perpendicular to the warp threads and determined by the guides 18.
Das Element 13 wird mittels eines Antriebes, bei dem Ausführungsbeispiel mittels eines Exzenterantriebes, parallel zu der Reihe der Nadeln 1 hin- und herbewegt. Bei dem dargestellten Ausführungsbeispiel ist an die Querstrebe 17 des Rahmens 15 eine Verbindungsstange 24 angelenkt, die über einen Exzenter 25 von der Antriebswelle 27 eines regelbaren Antriebsmotors 28 angetrieben wird, um das Element 13 in Richtung des Pfeiles L hin- und herzubewegen. Der Antriebsmotor 28 ist bei dem Ausführungsbeispiel an dem Querbalken 8 befestigt. Er ist beispielsweise ein regelbarer, schaltbarer Reluktanzmotor. Der Exzenter 25 ist mittels Schrauben 26 auf einer Scheibe 33 befestigt, die drehfest auf der Antriebswelle 27 angeordnet ist. Der Exzenter 25 kann bei gelockerten Schrauben in Schlitzen 29 der Scheibe 33 verschoben und durch Festziehen der Schrauben 26 in einer vorgegeben radialen Stellung auf der Scheibe 33 befestigt werden. Dadurch ist es möglich, die Amplitude der Bewegung einzustellen, beispielsweise in Abhängigkeit von dem Abstand zwischen den Führungsaugen 14 des Elements 13. Wie aus Fig. 2 weiter zu ersehen ist, besteht die Verbindungsstange aus zwei Teilen 24A und 24B, die mittels Schrauben 30 und Schlitzen 31 in unterschiedlichen Axialpositionen miteinander verbunden werden können, so dass die Länge der Verbindungsstange 24 eingestellt werden kann. Dadurch kann die Position der Führungsaugen 14 des Elementes 13 in seitlicher Richtung bezüglich der Nadeln 1 eingestellt werden. Die Verbindungsstange 24 ist mittels eines Gelenks 32 mit der Querstrebe 17 verbunden. Die Querstrebe 17 ist mittels mehrerer über ihre Länge verteilt angeordneter Führungen 34, 35 geführt, die an den Stützen 9 angebracht sind und die verhindern, dass sich die Querstrebe 17 in Richtung der Kettfäden durchbiegt. Bei dem dargestellten Ausführungsbeispiel befinden sich die Antriebswelle 27 und die Verbindungsstange 24 nahezu in einer horizontalen Ebene 36, wenn sich das Element zwischen seiner obersten und seiner untersten Position befindet. Die Verbindungsstange verläuft dann im wesentlichen parallel zu der Querstrebe 17. In der untersten Position des Elementes 13 befinden sich die von diesem geführten Kettfäden unterhalb der Nadeln 1 und liegen deshalb nicht an den stationären Nadeln 1 an.The element 13 is moved back and forth parallel to the row of needles 1 by means of a drive, in the exemplary embodiment by means of an eccentric drive. In the illustrated embodiment, a connecting rod 24 is articulated to the cross strut 17 of the frame 15, which is driven via an eccentric 25 by the drive shaft 27 of a controllable drive motor 28 in order to move the element 13 back and forth in the direction of the arrow L. The drive motor 28 is fastened to the crossbar 8 in the exemplary embodiment. For example, it is a controllable, switchable reluctance motor. The eccentric 25 is fastened by means of screws 26 on a disk 33 which is arranged on the drive shaft 27 in a rotationally fixed manner. When screws are loosened, the eccentric 25 can be moved in slots 29 of the disk 33 and fastened on the disk 33 in a predetermined radial position by tightening the screws 26. This makes it possible to adjust the amplitude of the movement, for example depending on the distance between the guide eyes 14 of the element 13. As can further be seen from FIG. 2, the connecting rod consists of two parts 24A and 24B, which are fastened by means of screws 30 and Slots 31 can be connected to each other in different axial positions, so that the length of the connecting rod 24 can be adjusted. As a result, the position of the guide eyes 14 of the element 13 can be adjusted in the lateral direction with respect to the needles 1. The connecting rod 24 is connected to the cross strut 17 by means of a joint 32. The cross strut 17 is guided by means of a plurality of guides 34, 35 distributed over its length, which are attached to the supports 9 and which prevent the cross strut 17 from bending in the direction of the warp threads. In the illustrated embodiment, the drive shaft 27 and the connecting rod 24 are almost in a horizontal plane 36 when the element is between its uppermost and its lowest position. The connecting rod then runs essentially parallel to the cross strut 17. In the lowest position of the element 13, the warp threads guided by it are below the needles 1 and therefore do not rest on the stationary needles 1.
Wie aus Fig. 3 zu sehen ist, wird eine Kettfadenschar 37 von den Führungsaugen 14 des Elementes 13 geführt. Die andere Kettfadenschar 38 läuft über die Umlenkstange 11 zu den Führungsaugen 39 der Nadeln 1. Die Kettfäden der Kettfadenscharen 37, 38 werden von einem nicht dargestellten Kettbaum, beispielsweise über einen federnd montierten Streichbaum, zu der erfindungsgemäßen Vorrichtung geführt. Zwischen dem Streichbaum und der erfindungsgemäßen Vorrichtung können gegebenenfalls noch Mittel zum Kompensation der Spannungsänderungen in den Kettfäden der Kettfadenscharen 37, 38 angeordnet sein.As can be seen from Fig. 3, a warp 37 is guided by the guide eyes 14 of the element 13. The other warp thread family 38 runs over the deflecting rod 11 to the guide eyes 39 of the needles 1. The warp threads of the warp thread families 37, 38 are guided to the device according to the invention by a warp beam, not shown, for example via a spring-mounted match tree. Means for compensating for the changes in tension in the warp threads of the warp thread groups 37, 38 can optionally also be arranged between the match tree and the device according to the invention.
Wie in Fig. 4 dargestellt ist, werden jeweils ein Kettfaden der Kettfadenschar 37 und ein Kettfaden der Kettfadenschar 38 zwischen zwei Zähnen 40 eines Webblattes 41 geführt. Diese Kettfäden, die zwischen zwei Web- blattzähnen 40 geführt werden, sollen zusammen eine Dreherbindung bilden. Dadurch entsteht ein Drehergewebe 42, wenn entsprechend Schussfäden 43 eingebracht werden.As shown in FIG. 4, one warp thread of the warp thread family 37 and one warp thread of the warp thread family 38 are guided between two teeth 40 of a reed 41. These warp threads, which are guided between two reed teeth 40, should together form a leno weave. This creates a leno fabric 42 when wefts 43 are inserted accordingly.
Wie in Fig. 5 dargestellt ist, ist das Webblatt 41 auf einer Weblade 44 montiert. Die Kettfadenscharen 37 und 38 bilden ein Webfach 45, wobei die untere Kettfadenschar 38 des Webfaches 45 von den Kettfäden gebildet wird, die von den stationär angeordneten Nadeln 1 geführt werden. Die obere Kettfadenschar 37 wird von den Kettfäden gebildet, die von dem Element 13 geführt werden.As shown in FIG. 5, the reed 41 is mounted on a sley 44. The warp thread groups 37 and 38 form a shed 45, the lower warp thread set 38 of the shed 45 being formed by the warp threads which are guided by the needles 1 arranged in a stationary manner. The upper warp thread sheet 37 is formed by the warp threads which are guided by the element 13.
Beim Weben wird beispielsweise, ausgehend von der Position nach Fig. 5 und 6, bei denen sich die Kettfäden der Kettfadenschar 37 in ihrer obersten Position und links von den zugehörigen Nadeln 1 befinden, das Element 13 nach unten bewegt. Während dieser Bewegung kann das Element 13 mit den Kettfäden der Kettfadenschar 37 mittels des Antriebsmotors 28 seitlich in Richtung zu den Nadeln 1 bewegt werden, wie dies in Fig. 7 und 8 dargestellt ist. Bei der Weiterbewegung in die Position nach Fig. 9 und 10 kann durch eine weitere seitliche Bewegung des Elements 13, wie dies in Fig. 11 dargestellt ist, erreicht werden, dass die Kettfäden der Kettfadenschar 37 auf die andere Seite der jeweiligen Nadel 1 gebracht werden. Bei einer anschließenden Aufwärtsbewegung des Elementes 13 bleiben die Kettfäden der Kettfadenschar 37 auf dieser Seite der zugehörigen Nadel 1 , so dass sich eine Position entsprechend Fig. 12 und 13 ergibt. Wenn dann jeweils Schussfäden 43 eingetragen werden, wird ein Drehergewebe 42 entsprechend Fig. 4 erhalten.During weaving, for example, starting from the position according to FIGS. 5 and 6, in which the warp threads of the warp thread family 37 are in their uppermost position and to the left of the associated needles 1, the element 13 is moved downward. During this movement, the element 13 with the warp threads of the warp thread family 37 can be moved laterally in the direction of the needles 1 by means of the drive motor 28, as is shown in FIGS. 7 and 8. When moving further into the position according to FIGS. 9 and 10, a further lateral movement of the element 13, as shown in FIG. 11, can bring the warp threads of the warp thread family 37 to the other side of the respective needle 1 , During a subsequent upward movement of the element 13, the warp threads of the warp thread family 37 remain on this side of the associated needle 1, so that a position corresponding to FIGS. 12 and 13 results. If weft threads 43 are then inserted in each case, a leno fabric 42 corresponding to FIG. 4 is obtained.
Es ist selbstverständlich möglich, den Antriebsmotor 28 so zu steuern, dass das Element 13 nicht bei jedem Eintrag seitlich bewegt wird, sondern nur nach definierten Einträgen. In diesem Fall wird ein Drehergewebe erzeugt, bei dem die Kettfäden der Kettfadenscharen 37 und 38 nicht um jeden Schussfaden 43 eine Dreherbindung bilden, sondern nur nach einer Gruppe von mehreren Schussfäden. Selbstverständlich muss auch das Element 13 nicht für jeden Schusseintrag von der obersten in die unterste und wieder in die oberste Höhenposition gebracht werden. Es kann vorgesehen werden, dass diese Bewegung nur nach einer vorgegebenen Anzahl von Schusseinträgen erfolgt. Selbstverständlich sind auch Kombinationen der vorstehend beschriebenen Bewegungen möglich. Durch entsprechende Steuerung des Antriebsmotors 28 zu einer seitlichen Bewegung in beiden Richtungen mit dem Element 13 relativ zur Auf- und Abwärtsbewe- gung können Kettfäden der Kettfadenschar 37 in der untersten Position des Elementes 13 auf die gewünschte Seite der Nadeln 1 gebracht werden, um die entsprechende Dreherbindung zu erhalten.It is of course possible to control the drive motor 28 so that the element 13 is not moved laterally with each entry, but only after defined entries. In this case, a leno fabric is produced in which the warp threads of the warp thread groups 37 and 38 do not form a leno weave around each weft thread 43, but only after a group of several weft threads. Of course, the element 13 does not have to be brought from the top to the bottom and back to the top height position for every weft insertion. It can be provided that this movement takes place only after a predetermined number of weft entries. Of course, combinations of the movements described above are also possible. By appropriate control of the drive motor 28 for a lateral movement in both directions with the element 13 relative to the up and down movement supply warp threads of the warp thread array 37 can be brought to the desired side of the needles 1 in the lowest position of the element 13 in order to obtain the corresponding leno binding.
Bevorzugt wird die Herstellung eines Drehergewebes 42, bei welchem das Element 13 während jedes Eintrags seitlich in die eine oder die andere Richtung bewegt wird und bei welchem das Element 13 zwischen jedem Eintrag eine Auf- und Abwärtsbewegung ausführt, da in diesem Fall ein gut gebundenes Drehergewebe 42 erhalten wird. Ein derartiges Drehergewebe 42 ist insbesondere für die Verwendung als Teppichrücken geeignet. Damit wird auch der Vorteil erhalten, dass der Antriebsmotor 28 in eine Richtung mit nahezu konstanter Geschwindigkeit rotieren kann. Die Geschwindigkeit verläuft synchron zur Webmaschinengeschwindigkeit mit der halben Durchschnittsgeschwindigkeit. Die Geschwindigkeit des Antriebsmotors 28 muss nicht absolut synchron zur kontinuierlich veränderlichen Geschwindigkeit der Webmaschine sein. Sie muss nur im Mittel synchron zur Webmaschinengeschwindigkeit verlaufen. Dies bedeutet auch, dass der Antriebsmotor 28 so angetrieben werden muss, dass die von dem Element 13 geführten Kettfäden der Kettfadenschar 37 zu dem Zeitpunkt auf der gewünschten Seite der Nadeln positioniert werden, zu welchem die Kettfäden bei ihrer Aufwärtsbewegung gerade die Nadeln 1 passieren. Das Element kann sich zwischen den zwei oben genannten Zeitpunkten praktisch in einer beliebigen seitlichen Position befinden. Bevorzugt wird allerdings, dass sich das Element 13 zwischen den zwei vorstehend genannten Zeitpunkten in einer Position befindet, in welcher die Kettfäden möglichst nicht an den Nadeln 1 anliegen, um einen Verschleiß der Kettfäden und der Nadeln 1 aufgrund der Reibung der Kettfäden an den Nadeln 1 zu begrenzen. Im dargestellten Beispiel bedeutet das, dass der Exzenter 25 vom Antriebsmotor 28 beispielsweise pro Eintrag eines Schussfadens 43 um 180° verdreht wird, wobei der Antriebsmotor 28 mit veränderlicher Geschwindigkeit angetrieben wird. Diese veränderliche Geschwindigkeit kann so eingestellt werden, dass das Element 13 sich im wesentlichen in seitlicher Richtung zu einer Zeit bewegt, zu welcher sich dieses Element 13 im wesentlichen in der untersten Höhenposition unterhalb der Nadeln 1 befindet.Preferred is the manufacture of a leno fabric 42 in which the element 13 is moved laterally in one direction or the other during each entry and in which the element 13 performs an up and down movement between each entry, since in this case a well-bound leno fabric 42 is obtained. Such a leno fabric 42 is particularly suitable for use as a carpet back. This also has the advantage that the drive motor 28 can rotate in one direction at an almost constant speed. The speed is synchronized with the weaving machine speed at half the average speed. The speed of the drive motor 28 does not have to be absolutely synchronous with the continuously variable speed of the weaving machine. It only has to run synchronously with the weaving machine speed on average. This also means that the drive motor 28 must be driven in such a way that the warp threads of the warp thread family 37 guided by the element 13 are positioned on the desired side of the needles at the point in time at which the warp threads just pass the needles 1 during their upward movement. The element can practically be in any lateral position between the two times mentioned above. However, it is preferred that the element 13 is in a position between the two times mentioned above in which the warp threads do not rest against the needles 1, in order to prevent wear of the warp threads and the needles 1 due to the friction of the warp threads on the needles 1 to limit. In the example shown, this means that the eccentric 25 is rotated by the drive motor 28, for example per entry of a weft thread 43, by 180 °, the drive motor 28 being driven at a variable speed. This variable speed can be adjusted so that the element 13 is essentially in the lateral direction moved at a time when this element 13 is substantially in the lowest height position below the needles 1.
Bei dem Ausführungsbeispiel nach Fig. 14 ist das quer und parallel zu den stationären Nadeln 1 bewegliche Element in zwei Elemente 47 und 48 geteilt. Das Element 47 ist mit parallel zu den Nadeln 1 verlaufenden Führungsschlitzen 46 versehen. Es wird mittels eines an der Trägerplatte 3 angebrachten Antriebsmotors 28 und eines Exzenterantriebs mittels einer Verbindungsstange quer zu den Nadeln 1 in Richtung des Pfeiles L hin- und herbewegt. Die durch die Führungsschlitze 46 laufenden Kettfäden sind außerdem in einem Querschlitz 49 des Elementes 48 geführt, das mittels Seitenteilen und einer Querstrebe 50 in Führungen 18 geführt und zu Bewegungen parallel zu den Nadeln 1 in Richtung des Pfeiles S angetrieben ist. Die Schlitzführungen 46 und der Schlitz 49 bilden Führungsaugen für die Kettfäden der Kettfadenschar 37, die relativ zu den Nadeln 1 bewegt werden. Das Element 47 ist mit balkenförmigen Ansätzen 51 in Führungen 52 geführt, die an der Trägerplatte 3 angebracht sind.In the exemplary embodiment according to FIG. 14, the element which is movable transversely and parallel to the stationary needles 1 is divided into two elements 47 and 48. The element 47 is provided with guide slots 46 running parallel to the needles 1. It is moved back and forth across the needles 1 in the direction of arrow L by means of a drive motor 28 attached to the carrier plate 3 and an eccentric drive by means of a connecting rod. The warp threads running through the guide slots 46 are also guided in a transverse slot 49 of the element 48 which is guided in guides 18 by means of side parts and a cross strut 50 and is driven to move parallel to the needles 1 in the direction of the arrow S. The slot guides 46 and the slot 49 form guide eyes for the warp threads of the warp thread family 37, which are moved relative to the needles 1. The element 47 is guided with bars 51 in guides 52, which are attached to the carrier plate 3.
In Fig. 15 ist eine Ausführungsform dargestellt, die mit Ausnahme des Antriebs der Querbewegung des Elements 13 dem Ausführungsbeispiel nach Fig. 1 entspricht. An der Grundplatte der Führung 18 ist ein steuerbarer Linearmotor 53 angebracht, der einen ausfahrbaren Kolben 54 antreibt, der mit einem quer gerichteten Zapfen 55 versehen ist. Der Zapfen 55 greift in einen in Richtung der Hub-Bewegung verlaufenden Schlitz 56 eines Führungsblockes 57 ein, der an dem Seitenteil 16 des Rahmens 15 befestigt ist. Mittels des auf einen entsprechend eingestellten Geschwindigkeitsverlaufs angetriebenen Antriebsmotors 53 kann der Rahmen 15 seitlich zu den Nadeln so bewegt werden, dass Reibung zwischen den Kettfäden und den Nadeln 1 nur in beschränktem Maße auftritt. Bei einer Auf- und Abwärtsbewegung des Rahmens 15 gleitet der Zapfen 55 in dem Schlitz 56. Gemäß einer nicht dargestellten Variante kann auch die Auf- und Abbewe- gung des Rahmens 15 mit Hilfe eines eigenen Motors, beispielsweise eines Linearmotors, durchgeführt werden. Ebenso ist es auch möglich, diese Bewegung von einer anderen Welle der Webmaschine abzuleiten, beispielsweise von der Ladenwelle.FIG. 15 shows an embodiment which corresponds to the exemplary embodiment according to FIG. 1 with the exception of the drive for the transverse movement of the element 13. A controllable linear motor 53 is attached to the base plate of the guide 18 and drives an extendable piston 54 which is provided with a transversely directed pin 55. The pin 55 engages in a slot 56 in the direction of the stroke movement of a guide block 57 which is fastened to the side part 16 of the frame 15. By means of the drive motor 53 driven to an appropriately set speed profile, the frame 15 can be moved laterally to the needles in such a way that friction between the warp threads and the needles 1 only occurs to a limited extent. When the frame 15 moves up and down, the pin 55 slides in the slot 56. According to a variant not shown, the up and down movement of the frame 15 can also be carried out with the aid of a separate motor, for example a linear motor. It is also possible to derive this movement from another shaft of the weaving machine, for example from the loading shaft.
Bei der Ausführungsform nach Fig. 16 ist die Umlenkstange 11 an der Trägerplatte 13 federelastisch nachgiebig gehalten. Hierzu sind das Klemmelement 12 und die Halter 10 beweglich in parallel zu den Nadeln 1 verlaufenden Führungen geführt und mittels Federn 63 an einem Halteteil 64 der Trägerplatte 3 aufgehängt. Damit ist es möglich, Spannungsänderungen in der Kettf adenschar 38 zu begrenzen.In the embodiment according to FIG. 16, the deflecting rod 11 is held on the carrier plate 13 in a resilient manner. For this purpose, the clamping element 12 and the holder 10 are movably guided in guides running parallel to the needles 1 and suspended by means of springs 63 on a holding part 64 of the carrier plate 3. It is thus possible to limit changes in tension in the warp thread family 38.
Bei der Ausführungsform nach Fig. 16 ist ferner vorgesehen, dass die Verbindungsstange 20 nicht mittels eines Drehgelenkes an den Rahmen 15 angelenkt ist. Die Verbindungsstange 20 ist federelastisch verformbar (biegbar), so dass ein Gelenk entfallen kann. Bevorzugt wird vorgesehen, dass die Verbindungsstange 20 eine definierte Biegestelle 61 in Form einer Materialschwächung aufweist. Die Verbindungsstange 20 ist bei diesem Ausführungsbeispiel dann mit einem Halter 62 fest mit dem Rahmen 15 verbunden.In the embodiment according to FIG. 16 it is further provided that the connecting rod 20 is not articulated to the frame 15 by means of a swivel joint. The connecting rod 20 is resiliently deformable (bendable) so that a joint can be omitted. It is preferably provided that the connecting rod 20 has a defined bending point 61 in the form of a material weakening. The connecting rod 20 is then firmly connected to the frame 15 with a holder 62 in this embodiment.
Bei einer abgewandelten Ausführungsform ist die Umlenkstange 11 oben an dem Rahmen 15 befestigt. Bei einer weiter abgewandelten Ausführungsform sind anstelle einer Umlenkstange 11 einzelne Fadenführer oben an dem Rahmen befestigt.In a modified embodiment, the deflecting rod 11 is attached to the frame 15 at the top. In a further modified embodiment, 11 individual thread guides are attached to the top of the frame instead of a deflecting rod.
Bei einer nicht dargestellten Ausführungsform wird vorgesehen, dass auch das Element 13 oder 47 von dem Hauptantrieb der Webmaschine angetrieben wird. Ein derartiger Antrieb besteht beispielsweise aus einem von einer Welle der Webmaschine angetriebenen Nocken, der über Verbindungsstangen mit dem Element 13 oder 47 verbunden ist. Bei einer derar- tigen Ausführungsform ist allerdings die Möglichkeit der Variation der Dreherbindungen begrenzt.In one embodiment, not shown, it is provided that the element 13 or 47 is also driven by the main drive of the weaving machine. Such a drive consists, for example, of a cam driven by a shaft of the weaving machine, which is connected to the element 13 or 47 via connecting rods. With such a term embodiment, however, the possibility of varying the leno bindings is limited.
Obwohl die vorliegende Erfindung am Beispiel einer Luftdüsenwebmaschine dargestellt worden ist, ist ihre Anwendung nicht darauf beschränkt. Sie ist ohne weiteres auch in Verbindung mit anderen Webmaschinen, beispielsweise Greiferwebmaschinen, Greiferschützenwebmaschinen, Wasserstrahlwebmaschinen, Projektilwebmaschinen oder anderen Webmaschinen einsetzbar. Dabei besteht der Vorteil, dass die erfindungsgemäße Vorrichtung praktisch an jeder Webmaschine problemlos nachträglich angebaut werden kann.Although the present invention has been illustrated using the example of an air jet weaving machine, its application is not restricted to this. It can also be used in conjunction with other weaving machines, for example rapier weaving machines, rapier shooters, water jet weaving machines, projectile weaving machines or other weaving machines. The advantage here is that the device according to the invention can be easily retrofitted to practically any weaving machine.
Die vorstehend beschriebenen Ausführungsformen dienen nur zur Erläuterung der Erfindung, die auch in anderen Ausführungsformen ohne weiteres realisiert werden kann The embodiments described above serve only to explain the invention, which can also be easily implemented in other embodiments
