Abstract

The present invention relates to a gripper loom having a feed gripper (11) and a take-up gripper. The feed gripper (11) has in its cover plate an orifice (40) which is closed on itself and through which the weft yarn (14) is guided. The orifice (40) has a rearwardly extending narrowing (41) which guides the weft yarn (14) exactly in the mid-plane of the gripper (11). The advantage of the invention in comparison with the state of the art is to be seen in that the weft yarn does not have to be threaded in anew in the gripper (11) at each weft insertion, and in that it is guided exactly along the mid-plane of the gripper (11). This reduces the danger of fibril breaks in the processing of glass-fibre and chemical-fibre yarns and the soiling of the fabric. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf eine Greiferwebmaschine von der im Oberbegriff des Patentanspruches 1 bekannten Art. Beispiele eines im Oberbegriff erwähnten Bringergreifers sind aus den Figuren 1 und 4 der Europäischen Patentanmeldung EP-A-0 272 206 ersichtlich.The present invention relates to a rapier weaving machine of the type known in the preamble of claim 1. Examples of a rapier gripper mentioned in the preamble can be seen in FIGS. 1 and 4 of European patent application EP-A-0 272 206.

Bei bekannten Greiferwebmaschinen muss jeder Schussfaden mittels eines Fadenvorlegers dem Bringer von der Seite her dargeboten werden. Dies ist eine Ursache von Verschmutzungen des Gewebes. Ausserdem muss der dargebotene Faden zwischen zwei Einfädlerspitzen hindurch bewegt werden, was ein Hängenbleiben oder Beschädigen des Fadens durch die Spitzen und Qualitätseinbussen des Gewebes wegen des Vorhandenseins einzelner im Gewebe eingeschlossener Fibrillenbrüche bewirken kann.In known rapier weaving machines, each weft thread must be presented to the bringer from the side by means of a thread feeder. This is a cause of tissue contamination. In addition, the presented thread must be moved between two threader tips, which can cause the thread to get caught or damaged due to the tips and loss of quality of the tissue due to the presence of individual fibril breaks enclosed in the tissue.

Die Laschen (siehe z.B. Lasche 42 der obigen Europäischen Patentanmeldung) können ebenfalls die Ursache von beim Weben auftretenden Schwierigkeiten sein.The tabs (see e.g. tab 42 of the above European patent application) can also be the cause of difficulties encountered in weaving.

Diese Nachteile sollen gemäss der Erfindung vermieden werden. Diese weist die im kennzeichnenden Teil des Patentanspruches aufgeführten Merkmale auf und sei im folgenden anhand der Figuren der Zeichnung näher erläutert. In der letzteren sindThese disadvantages are to be avoided according to the invention. This has the features listed in the characterizing part of the claim and is based on the Figures of the drawing explained in more detail. In the latter are

Fig. 1 und 2 zwei Ansichten von oben gesehen, die zur Erläuterung des Schusseintrages mit Greiferbringern bei bekannten Webverfahren dienen.1 and 2 two views seen from above, which serve to explain the weft insertion with rapier in known weaving methods.

Fig. 3 zeigt einen Schussfadeneintragsvorgang bei einer Webmaschine mit einem neuen Bringergreifer.Fig. 3 shows a weft insertion process in a weaving machine with a new rapier.

Es sei auch auf die mit dieser Patentanmeldung gleichentags getätigte Parallelanmeldung Nr CH 02899/90-6 verwiesen.Reference is also made to parallel application No. CH 02899 / 90-6 made on the same day with this patent application.

Figur 1 zeigt einen Bringergreifer (Bringer) 11, der mit einer durch dessen Deckplatte verdeckten Fadenklemme (Klemme) 12 versehen ist. Der Bringer 11 ist mit einem als Antriebsorgan dienenden Antriebsband 13 fest, welches in bekannter Weise die Hin- und Herbewegung des Bringers 11 bewirkt. Ein Schussfaden 14 läuft von einem ortsfesten Schussfadenvorrat 15 über einen Fadenvorleger 19 zu einem Gewebe 16, in welchem es den zuletzt eingewobenen Schussfaden bildet. Durch Kettfäden wird ein Webfach 17 gebildet. Eine Schere 18 dient zum Schneiden des Schussfadens 14. Der schematisch gezeichnete Fadenvorleger dient zum Uebergeben des Fadens 14 an den Bringer 11.FIG. 1 shows a bringer gripper (bringer) 11 which is provided with a thread clamp (clamp) 12 hidden by its cover plate. The bringer 11 is fixed with a drive belt 13 serving as a drive member, which causes the bringer 11 to move back and forth in a known manner. A weft thread 14 runs from a stationary weft thread supply 15 via a thread feeder 19 to a fabric 16 in which it forms the last woven-in thread. A shed 17 is formed by warp threads. A pair of scissors 18 is used to cut the weft thread 14. The schematically drawn thread feeder is used to transfer the thread 14 to the carrier 11.

Im Betrieb der Webmaschine bewegt sich in bekannter Weise der Bringer 11 nach links in das offene Webfach 17 hinein. Dabei muss der Fadenvorleger 19 den Faden 14 in der Weise führen, dass dieser zwischen den Einfädlerspitzen 20,21 des Bringers 11 eingefädelt wird. Um dies in der Praxis durchzuführen, muss sich der Fadenvorleger 19 auf der der Webfachspitze 22 abgewandten Seite des Bringers 11 befinden. Bei der Weiterbewegung des letzteren wird der Faden 14, welcher in diesem Zeitpunkt bereits eingewoben und daher vom Gewebe 16 gehalten und zudem im Fadenvorleger 19 gebremst ist, in den Bringer 11 hinein zur Klemme 12 gebracht und von dieser gehalten.Darauf wird der Faden 14 mittels der Schere 18 geschnitten. In der Mitte des Webfaches wird in bekannter Weise der von der Klemme 12 gehaltene Fadenteil von einem mit dem Bringer 11 zusammenarbeitenden, in der Figur 1 nicht gezeigten Nehmergreifer übernommen.In operation of the weaving machine, the bringer 11 moves to the left into the open shed 17. The thread feeder 19 must guide the thread 14 in such a way that it is threaded between the threading tips 20, 21 of the feeder 11. In order to do this in practice, the thread feeder 19 must be on the side of the applier 11 facing away from the shed tip 22. When the latter moves further, the thread 14, which is already woven in at this point in time and is therefore held by the fabric 16 and is also braked in the thread feeder 19, is brought into the clamp 11 into the clamp 12 The thread 14 is then cut with the scissors 18. In the middle of the shed, the thread part held by the clamp 12 is taken over in a known manner by a slave rapier, not shown in FIG.

In Figur 2 sind wiederum der Bringer 11 mit der Klemme 12 und den Spitzen 21,22, das Antriebsband 13, der Schussfaden 14 und der Fadenvorleger 19 gezeigt. Zusätzlich ist noch eine Lade 23 gezeichnet. Die auf der rechten Seite derselben gezeigte Verlängerung 24 ist feststehend und gehört zum Maschinengestell, auf dem auch der Fadenvorleger 19 befestigt ist.In Figure 2, the bringer 11 with the clamp 12 and the tips 21, 22, the drive belt 13, the weft thread 14 and the thread feeder 19 are shown again. In addition, a drawer 23 is drawn. The extension 24 shown on the right side thereof is fixed and belongs to the machine frame on which the thread feeder 19 is also attached.

Für die Uebergabe des Schussfadens 14 vom Bringer 13 zum Nehmergreifer müssen diese zum Stillstand gebracht werden. Es kann nicht vermieden werden, dass bei dieser enormen Abbremsung des Bringers 11 der Faden 14 kurzzeitig etwas locker wird. Dadurch kann er bei diesem Uebergabevorgang auf das Antriebsband 13 fallen. Der Faden 14 kommt bei diesem Vorgang als Folge der im vorherigen erwähnten seitlichen Position des Vorlegers 19 in der in Figur 2 durch den Faden 14 gezeigten Lage in einen spitzen Winkel zum Antriebsband 13 zu liegen.For the transfer of the weft thread 14 from the bringer 13 to the slave gripper, these have to be brought to a standstill. It cannot be avoided that with this enormous braking of the bringer 11 the thread 14 becomes somewhat loose for a short time. As a result, he can fall onto the drive belt 13 during this transfer process. In this process, the thread 14 comes to lie at an acute angle to the drive belt 13 in the position shown by the thread 14 in the position shown in FIG.

In der Regel werden diese Antriebsbänder 13, um ihr Gewicht klein zu halten, aus Kohlefasern hergestellt. Da die Bänder in seitlichen Führungen geführt sind, weisen ihre Seitenkanten einen Belag feinen Staubes auf. Dieser verschmutzt die darauf fallenden Schussfäden 14 und bewirkt Einbussen der Qualität, da dadurch das Gewebe ebenfalls verschmutzt wird. Dieser Nachteil tritt vor allem bei Kohlefaserbändern 13, aber auch bei Bändern aus anderem Material,auf.As a rule, these drive belts 13 are made of carbon fibers in order to keep their weight small. Since the belts are guided in side guides, their side edges have a coating of fine dust. This contaminates the weft threads 14 falling thereon and causes a loss of quality, since this also causes the fabric to become dirty. This disadvantage occurs primarily with carbon fiber tapes 13, but also with tapes made of a different material.

Eine beispielsweise Ausführungsform der Erfindung, bei welcher dieser Nachteil vermieden ist, sei anhand der Figur 3 erläutert. In dieser Figur werden Teile mit gleicher Funktion wie Teile der Figuren 1 und 2 mit gleichen Bezugszahlen bezeichnet. Figur 3 zeigt wiederum einen Bringergreifer oder Bringer 11, der wiederum eine Fadenklemme 12 aufweist. Im weiteren sind wieder ein als Antriebsorgan dienendes Antriebsband 13, ein von einem Schussfadenvorrat 15 herkommender Schussfaden 14, ein Gewebe 16, Kettfäden eines Webfaches 17 und eine Schere 18 zum Schneiden des Schussfadens 14 vorgesehen.An exemplary embodiment of the invention in which this disadvantage is avoided is shown in FIG. 3 explained. In this figure, parts with the same function as parts of Figures 1 and 2 are denoted by the same reference numerals. FIG. 3 again shows a bringer gripper or bringer 11, which in turn has a thread clamp 12. Furthermore, a drive belt 13 serving as a drive element, a weft thread 14 coming from a weft thread supply 15, a fabric 16, warp threads of a shed 17 and a pair of scissors 18 are provided for cutting the weft thread 14.

Im Unterschied zu den heute bekannten Ausführungen ist jedoch der Fadenvorleger 19 nicht mehr seitlich der Bewegungsbahn des Bringers 11 angebracht, sondern der Fadenvorleger 19 befindet sich im wesentlichen senkrecht über der gedachten Mittellinie des in der Längsrichtung des bandförmigen, als Antriebsorgan für den Bringer 11 dienenden, auf der Weblade 23 (Figur 2) aufliegenden Antriebsbandes 13.In contrast to the designs known today, however, the thread feeder 19 is no longer attached to the side of the movement path of the feeder 11, but the thread feeder 19 is located essentially perpendicularly above the imaginary center line of the band-shaped, in the longitudinal direction, serving as the drive element for the feeder 11, drive belt 13 resting on the sley 23 (FIG. 2).

Ausserdem erstreckt sich der Schussfaden 14 vom Fadenvorleger 19 zum Bringergreifer 11 bis zu einer Oeffnung 40 desselben durch die letztere hindurch und von dort an der Fadenklemme 12 vorbei zum Gewebe 16. Die Oeffnung 40 weist in bezug auf die Eintragsrichtung des Bringers 11 (in Figur 3 nach links) eine nach hinten gerichtete Verjüngung 41 auf, deren Ende durch eine kleine Abrundung 42 gebildet ist. Auch diese Abrundung 42 befindet sich mindestens ungefähr senkrecht über der im vorherigen Absatz erwähnten gedachten Mittellinie.In addition, the weft thread 14 extends from the thread feeder 19 to the feeder gripper 11 up to an opening 40 thereof through the latter and from there past the thread clamp 12 to the fabric 16. The opening 40 points with respect to the direction of entry of the feeder 11 (in FIG. 3 to the left) has a rearward taper 41, the end of which is formed by a small rounding 42. This rounding 42 is also at least approximately perpendicular to the imaginary center line mentioned in the previous paragraph.

Wenn im Betrieb der Webmaschine sich der Bringer 11 nach links bewegt, so zieht die Abrundung 42 den Schussfaden 14 mit sich. Dadurch gelangt er in die Fadenklemme 12, wobei die freien Seitenkanten der Oeffnung 40 bei der Führung des Fadens 14 zur Klemme 12 mitwirken. Unmittelbar nach dem Klemmen des Fadens 14 durch die Klemme 12 wird dieser mit der Schere 18 geschnitten und ins Webfach 17 eingetragen, in dessen Mitte er einem nicht gezeigten Nehmergreifer übergeben und von diesem noch vollständig ins Webfach 17 eingetragen wird. Dabei läuft der Faden 14 dauernd, auch während der Rückkehrbewegung des Bringers 11, durch die Oeffnung 40 hindurch. Beim Austritt des Bringers 11 aus dem Webfach 17 wird der neu eingezogene Schussfaden angeschlagen. Damit liegt der in Figur 3 gezeigte Zustand wieder vor. Der Faden 14 ist vor dem Webvorgang, während desselben und nach diesem, d.h. dauernd, in der Oeffnung 40 eingefädelt. Bezüglich der in Figur 1 gezeigten Arbeitsweise ist ein Einfädeln des Fadens 14 zwischen den Einfädlerspitzen 20,21 nicht notwendig und sind die erwähnten dadurch bedingten Nachteile,insbesondere die Gefahr der Fibrillenbrüche, eliminiert. Ein weiterer ganz wesentlicher Vorteil besteht darin, dass der Fadenvorleger 19 nicht mehr die in Figur 1 gezeigte,durch das Einfädeln zwischen den Einfädlerspitzen 20,21 bedingte, seitlich des Kopfes des Bringers 11 befindliche Position einnehmen muss. Dies erlaubt es, den Fadenvorleger 19 hinter der Umkehrposition des aus dem Webfach 17 ausgetretenen Bringers 11 anzubringen. Als Folge davon kann dieser auch mindestens ungefähr senkrecht über der im vorherigen bereits erwähnten gedachten Mittellinie des Antriebsbandes 13, welche in der Längsrichtung des auf der Lade aufliegenden Bandes 13 verläuft, angebracht werden.If, during operation of the weaving machine, the bringer 11 moves to the left, the rounding 42 pulls the weft thread 14 with it. As a result, it gets into the thread clamp 12, the free side edges of the opening 40 cooperating in guiding the thread 14 to the clamp 12. Immediately after the thread 14 has been clamped by the clamp 12, it is cut with the scissors 18 and inserted into the shed 17, in the middle of which it is handed over to a slave gripper, not shown, and is then completely entered into the shed 17. The thread 14 runs continuously through the opening 40, even during the return movement of the bringer 11. When the bringer 11 exits the shed 17, the newly drawn weft thread is cast on. The state shown in FIG. 3 is thus again present. The thread 14 is threaded into the opening 40 before, during and after the weaving process, ie continuously. With regard to the mode of operation shown in FIG. 1, threading the thread 14 between the threading tips 20, 21 is not necessary and the disadvantages mentioned, in particular the risk of fibril breaks, are eliminated. Another very important advantage is that the thread feeder 19 no longer has to assume the position shown on the side of the head of the bringer 11 as shown in FIG. This allows the thread feeder 19 to be attached behind the reversed position of the feeder 11 emerging from the shed 17. As a result, it can also be attached at least approximately vertically above the imaginary center line of the drive belt 13 already mentioned above, which runs in the longitudinal direction of the belt 13 resting on the drawer.

Wenn zum Zweck der Uebergabe des Schussfadens 14 vom Bringerzum Nehmergreifer diese zum Stillstand und abgebremst werden müssen und dabei der Faden 14 etwas locker wird, so fällt dieser auf die Mitte des Bandes 13 und wird somit durch die sich an dessen Rändern befindlichen Schmutzteilchen, Fibrillen oder die durch Abrieb sonstwie gebildeten Partikel nicht beschmutzt. Man erhält durch die Erfindung eine ganz erhebliche Verbesserung der Gewebequalität.

Figure imgb0001
If, for the purpose of transferring the weft thread 14 from the bringer to the gripper, these have to be brought to a standstill and braked and the thread 14 becomes somewhat loose, then this falls on the middle of the band 13 and is thus caused by the dirt particles, fibrils or on its edges the particles otherwise formed by abrasion are not soiled. The invention gives a very considerable improvement in the quality of the tissue.
