Description

La présente invention concerne l'industrie textile et plus particulièrement le domaine des machines à tisser sans navette.The present invention relates to the textile industry and more particularly to the field of shuttleless weaving machines.

Un moyen bien connu d'insérer la trame dans la foule d'une machine à tisser de ce type consiste à utiliser une paire d'aiguilles, rigides ou souples, animées d'un mouvement de va et vient en sens inverses entre les lisières et, généralement, le milieu de la laize. Chaque aiguille porte une pince dont l'une, fixée à l'aiguille dite d'entrée ou d'amenée saisit l'extrémité de la duite à insérer au voisinage de l'une des lisières et l'introduit dans la foule. Vers le milieu de la laize, elle transfère la duite à la pince fixée à l'autre aiguille, dite aiguille de sortie ou de tirage, qui, en reculant, l'entraîne jusqu'à l'autre lisière.A well-known means of inserting the weft into the crowd of a weaving machine of this type consists in using a pair of needles, rigid or flexible, animated back and forth in opposite directions between the selvedges and , generally, the middle of the width. Each needle carries a clamp, one of which, fixed to the so-called entry or supply needle, grasps the end of the pick to be inserted in the vicinity of one of the selvedges and introduces it into the crowd. Towards the middle of the width, it transfers the pick to the forceps attached to the other needle, known as the exit or draw needle, which, by moving back, carries it to the other edge.

L'invention concerne plus précisément un perfectionnement à la pince, dite pince de sortie, qui est fixée à l'extrémité de l'aiguille de sortie.The invention relates more precisely to an improvement to the clamp, called the outlet clamp, which is fixed to the end of the outlet needle.

Ce mode d'insertion devient de plus en plus délicat à mettre en oeuvre à mesure que la vitesse des machines à tisser s'accroît. En effet, l'aiguille d'entrée prend la duite alors qu'elle est soumise à une accélération considérable, ce qui peut provoquer la rupture du fil, surtout s'il est fin ou fragile. Le temps imparti à l'échange de la duite entre l'aiguille d'entrée et l'aiguille de sortie est de plus en plus court ; cet échange doit donc être rapide et cependant précis.This mode of insertion becomes more and more difficult to implement as the speed of the weaving machines increases. In fact, the entry needle picks up the pick while it is subjected to considerable acceleration, which can cause the wire to break, especially if it is thin or fragile. The time allowed for the exchange of the pick between the inlet needle and the outlet needle is shorter and shorter; this exchange must therefore be rapid and however precise.

Toutes ces considérations conduisent à chercher des pinces toujours plus légères, capables de saisir et de relâcher le fil avec précision et de circuler dans des foules qui se referment de plus en plus vite.All these considerations lead to the search for ever lighter pliers, capable of grasping and releasing the wire with precision and of circulating in crowds which close more and more quickly.

Le brevet DE-20 61 194 décrit une pince de sortie perfectionnée par rapport aux réalisations antérieures. Suivant ce brevet, le fil est pincé entre une partie fixe, en forme de crochet, solidaire du corps de pince, et une pièce centrale mobile, à ouverture commandée, dont l'extrémité s'engage dans l'ouverture du crochet pour y retenir le fil. Cependant, le fil est pincé entre deux facettes parallèles sensiblement verticales ; il se produit un double effet de coin, de sorte que le fil bloque la pince. Pour le libérer à la sortie de la laize, l'ouverture de la pince s'effectue en pressant sur la pièce centrale pour qu'elle s'éloigne du crochet, mais si le corps de la pince qui porte le crochet n'est pas suffisamment rigide, il suit la partie mobile et l'ouverture ne se fait pas. Pour éviter cet incident il faut un corps de pince massif, donc lourd.Patent DE-20 61 194 describes an improved output clamp compared to the previous embodiments. following In this patent, the wire is pinched between a fixed part, in the form of a hook, integral with the clamp body, and a movable central part, with controlled opening, the end of which engages in the opening of the hook to retain the wire. However, the wire is pinched between two substantially vertical parallel facets; there is a double wedge effect, so that the wire blocks the clamp. To release it at the exit of the width, the clamp is opened by pressing on the central part so that it moves away from the hook, but if the body of the clamp which carries the hook is not sufficiently rigid, it follows the mobile part and the opening is not made. To avoid this incident, you need a massive pliers body, therefore heavy.

Le but de la présente invention est de remédier à ces inconvénients en réalisant une pince de sortie légère, qui libère le fil d'une manière rapide et fiable. Le coincement de la pince par le fil est évité en pinçant celui-ci entre des facettes inclinées par rapport au plan de déplacement du crochet, celui-ci n'étant plus porté par le corps de pince mais par la partie mobile, ce qui permet de bénéficier de la pression du fil sur le crochet pour accentuer la force qui provoque sa fermeture.The object of the present invention is to remedy these drawbacks by making a light output clamp, which releases the wire in a rapid and reliable manner. The clamping of the clamp by the wire is avoided by pinching the latter between facets inclined relative to the plane of displacement of the hook, the latter no longer being carried by the clamp body but by the movable part, which allows to benefit from the pressure of the wire on the hook to accentuate the force which causes its closure.

L'invention consiste en une pince de sortie pour l'insertion de la trame dans une machine à tisser sans navette dans laquelle le fil est pincé entre une partie fixe et une partie mobile, l'une de ces parties affectant la forme d'un crochet, caractérisée en ce que le crochet est porté par la partie mobile et les deux facettes entre lesquelles est pincé le fil sont inclinées d'un certain angle par rapport au plan de déplacement de la partie mobile.The invention consists of an output clamp for inserting the weft in a shuttleless weaving machine in which the thread is pinched between a fixed part and a mobile part, one of these parts taking the form of a hook, characterized in that the hook is carried by the mobile part and the two facets between which the wire is pinched are inclined at a certain angle relative to the plane of movement of the mobile part.

La pince faisant l'objet de la présente invention se compose de deux pièces : le corps 1, fixe, solidaire de l'aiguille 2 et une partie mobile 3. Ces deux pièces sont liées en rotation par un axe 4 qui traverse le corps 1 et qui est rivé en 5 pour retenir la pièce 3.The clamp forming the subject of the present invention consists of two parts: the body 1, fixed, secured to the needle 2 and a movable part 3. These two parts are linked in rotation by an axis 4 which passes through the body 1 and which is riveted in 5 to retain part 3.

Le corps de pince 1 se compose d'une partie l' affectant la forme d'une équerre qui épouse les parois internes 9 et 10 de l'aiguille 2 (figure 3). Sur la représentation de la figure 1, les deux composants l' et 2 sont réunis par des vis 11 et 11' mais tous autressystèmesconnustelsque collage, rivetage, etc... peuvent être utilisés. Une lame de ressort 12 dont le rôle sera précisé ci-dessous est fixée à la pièce 1 par des vis 13.The clamp body 1 is made up of a part affecting it in the form of a square which matches the internal walls 9 and 10 of the needle 2 (FIG. 3). In the representation of FIG. 1, the two components 1 ′ and 2 are joined by screws 11 and 11 ′ but all other custom systems such as bonding, riveting, etc. can be used. A leaf spring 12, the role of which will be specified below, is fixed to part 1 by screws 13.

Le corps de pince 1 se termine par une partie 15 qui est la partie active pour le pincement du fil et qui coopère avec un crochet 14 porté par la partie mobile 3.The clamp body 1 ends in a part 15 which is the active part for pinching the wire and which cooperates with a hook 14 carried by the movable part 3.

En fonctionnement, la pince se déplace suivant les directions 6-6', comme représenté sur la figure l entre le peigne P et la façure F à partir de laquelle se forme le tissu T. Les fils de chaîne 7-7' ont également été représentés sur la figure 1.In operation, the clamp moves in directions 6-6 ′, as shown in FIG. 1 between the comb P and the face F from which the fabric T is formed. The warp threads 7-7 ′ have also been shown in Figure 1.

La partie active 15 de la pince (figure 5) présente une arête longitudinale 101, tournée vers la façure F et une arête 101' opposée à la première et qui limite l'une des facettes 102 de pincement du fil 19. Cette facette de pincement, qui coopère avec une facette correspondante opposée 16 prévue dans le crochet 14, présente deux inclinaisons : l'une par rapport au sens longitudinal de la pince qui donne à l'extrémité 15 de la pièce fixe une configuration de coin et l'autre par rapport au plan de déplacement de la partie mobile. Dans la réalisation décrite, la valeur de cette dernière inclinaison est d'environ 20° (figure 4). Cette valeur est définie comme sensiblement égale ou supérieure à la valeur angulaire limite permettant l'irréversibilité du coin formé dans la rainure 14' du crochet 14 par la partie 15 et le fil inséré 19. Cet angle est fonction du coefficient de frottement des surfaces en contact, c'est-à-dire de la nature du matériau constituant les parties fixe et mobile de la pince et aussi de la nature du fil. La liaison entre la facette droite 103 et la facette inclinée 102 est réalisée par une courbe 104 qui forme avec la courbe correspondante du crochet 14 l'ouverture d'insertion du fil 19. La zone 104 peut présenter une inclinaison supérieure à celle de la facette de pincement 102 pour faciliter l'insertion des fils les plus gros.The active part 15 of the clamp (FIG. 5) has a longitudinal edge 101, turned towards the face F and an edge 101 'opposite the first and which limits one of the facets 102 for pinching the wire 19. This pinch facet , which cooperates with a corresponding opposite facet 16 provided in the hook 14, has two inclinations: one relative to the longitudinal direction of the clamp which gives the end mity 15 of the part fixes a corner configuration and the other relative to the plane of movement of the mobile part. In the embodiment described, the value of this latter inclination is approximately 20 ° (FIG. 4). This value is defined as substantially equal to or greater than the limit angular value allowing the irreversibility of the corner formed in the groove 14 'of the hook 14 by the part 15 and the inserted wire 19. This angle is a function of the coefficient of friction of the surfaces in contact, that is to say the nature of the material constituting the fixed and movable parts of the clamp and also the nature of the wire. The connection between the straight facet 103 and the inclined facet 102 is produced by a curve 104 which forms with the corresponding curve of the hook 14 the insertion opening for the wire 19. The area 104 may have a greater inclination than that of the facet pinch 102 to facilitate the insertion of the largest wires.

L'extrémité de la partie mobile 3 opposée au crochet 14 s'appuie sur la lame de ressort 12. Elle comporte une partie 17 formant rampe , suivie d'une partie 18 sensiblement horizontale dans la position de fonctionnement de la pince.The end of the movable part 3 opposite the hook 14 rests on the spring leaf 12. It has a part 17 forming a ramp, followed by a part 18 which is substantially horizontal in the operating position of the clamp.

La pince qui vient d'être décrite et qui circule dans la foule avec la pointe 22 du crochet 14 tournée vers le peigne P fonctionne comme suit : sensiblement au milieu de la laize, le fil de trame 19 amené par une pince d'entrée (non représentée) est introduit entre les facettes 16 et 102, respectivement de la partie mobile 3 et de la partie fixe 1. Le brin tendu 19' du fil 19 qui est encore relié à la réserve de trame (non représentée) passe sur le crochet 14 et contribue à l'appliquer sur la partie fixe en regard, renforçant la fermeture de la pince qui est assurée par le ressort 12.The clamp which has just been described and which circulates in the crowd with the tip 22 of the hook 14 facing the comb P operates as follows: substantially in the middle of the width, the weft thread 19 brought by an input clamp ( not shown) is introduced between the facets 16 and 102, respectively of the movable part 3 and of the fixed part 1. The stretched strand 19 ′ of the wire 19 which is still connected to the weft reserve (not shown) passes over the hook 14 and contributes to applying it to the fixed facing part, reinforcing the closing of the clamp which is ensured by the spring 12.

Quand la pince a reculé jusqu'à ce que le crochet 14 arrive au niveau de la lisière, un galet fixe par rapport au bâti de la machine (non représenté) agit progressivement sur la rampe 17 puis appuie sur la partie 18 de la pièce mobile 3 et la fait basculer à l'encontre du ressort 12 autour de l'axe 4 sensiblement dans un plan perpendiculaire au plan du crochet 14, suivant la direction D indiquée par une flèche sur la figure 4. Le crochet 14 se soulève et libère le fil 19. Afin d'accroître la précision du mouvement de la partie mobile 3, celle-ci est guidée entre deux blocs de matière plastique 20, 21, fixés au corps de pince 1.When the clamp has retreated until the hook 14 arrives at the edge, a roller fixed relative to the frame of the machine (not shown) acts progressively on the ramp 17 then presses on the part 18 of the movable part 3 and causes it to tilt against the spring 12 around the axis 4 substantially in a plane perpendicular to the plane of the hook 14, in the direction D indicated by an arrow in FIG. 4. The hook 14 lifts and releases the wire 19. In order to increase the precision of the movement of the movable part 3, the latter is guided between two plastic blocks 20, 21, fixed to the clamp body 1.

Grâce au fait que le crochet est porté par la partie mobile de la pince et que le serrage du fil s'effectue entre deux facettes inclinées, on peut réaliser une pince plus rigide, donc d'un fonctionnement plus sûr, et plus légère que les pinces connues jusqu'à présent.Thanks to the fact that the hook is carried by the movable part of the clamp and that the tightening of the wire takes place between two inclined facets, it is possible to produce a more rigid clamp, therefore of a safer operation, and lighter than pliers known so far.

Il a été dit ci-dessus que la description qui précède s'applique au cas où la pointe 22 du crochet 14 est tournée du côté du peigne de la machine à tisser. Cependant, cette pince peut également fonctionner si elle est réalisée avec la pointe 22 du crochet 14 tournée du côté de la façure. Dans ce cas, il peut être avantageux que le plan du crochet 14 soit sensiblement parallèle à la nappe supérieure de la foule et que l'axe d'articulation 4 soit incliné de façon que la partie mobile 3 se déplace suivant un plan qui est oblique par rapport à un plan perpendiculaire au plan du crochet 14.It has been said above that the above description applies to the case where the tip 22 of the hook 14 is turned towards the comb side of the weaving machine. However, this clamp can also function if it is produced with the point 22 of the hook 14 turned towards the side of the facade. In this case, it may be advantageous for the plane of the hook 14 to be substantially parallel to the upper ply of the crowd and for the hinge pin 4 to be inclined so that the movable part 3 moves along a plane which is oblique. with respect to a plane perpendicular to the plane of the hook 14.
