Description

La présente invention a trait à un dispositif permettant d'amener les fils de chaîne dans trois positions différentes par l'intermédiaire de plusieurs cadres de griffes mobiles verticalement.The present invention relates to a device making it possible to bring the warp threads into three different positions by means of several claw frames movable vertically.

On sait qu'il existe des dispositifs du genre en question, qui comprennent généralement un seul cadre de griffes, comme décrit dans le brevet français N° 1 513 410 du 9 Décembre 1966.We know that there are devices of the kind in question, which generally include a single frame of claws, as described in French patent No. 1,513,410 of December 9, 1966.

Il s'agit plus particulièrement de faire coopérer deux crochets, commandés sélectivement par deux aiguilles, avec le même cadre de griffes. A chacune des extrémités des deux crochets sont fixées les extrémités d'une cordelette qui passe autour d'une poulie, laquelle est reliée par l'intermédiaire d'une biellette à une autre poulie, réalisant ainsi un moufle. Autour de cette seconde poulie passe une autre cordelette, dont l'une des extrémités est solidaire du bâti et l'autre comprend un collet associé à une lisse. Dans ce dispositif, les deux crochets sont sélectivement commandés par deux aiguilles, et les deux couteaux avec lesquels ils coopèrent font partie du même cadre de griffes, permettant ainsi à ce collet muni du fil de chaîne d'arriver soit dans une position haute, soit dans une position intermédiaire, ou soit dans une position basse. Les positions haute et basse sont respectivement atteintes lorsque les deux crochets sont retenus par le cadre de griffes et leur course verticale est équivalente à celle dudit cadre. La position intermédiaire est établie lorsqu'un seul des deux crochets est en prise avec le cadre de griffes, ce qui permet de déplacer le collet de la moitié de la course verticale du cas précédent.It is more particularly a question of making two hooks cooperate, selectively controlled by two needles, with the same frame of claws. At each end of the two hooks are fixed the ends of a cord which passes around a pulley, which is connected by means of a link to another pulley, thus producing a muffle. Around this second pulley passes another cord, one of the ends of which is integral with the frame and the other comprises a collar associated with a heddle. In this device, the two hooks are selectively controlled by two needles, and the two knives with which they cooperate are part of the same claw frame, thus allowing this collar provided with the warp thread to arrive either in a high position, or in an intermediate position, or either in a low position. The high and low positions are reached respectively when the two hooks are retained by the claw frame and their vertical stroke is equivalent to that of said frame. The intermediate position is established when only one of the two hooks is engaged with the claw frame, which allows the collar to be displaced by half of the vertical stroke of the previous case.

Il existe de même un brevet Suisse N° 367 452 du 19 Avril 1958 qui décrit une mécanique d'armure à double lève réalisée sous la forme de deux crochets réunis par un cordon qui passe, comme dans le brevet français, autour d'une poulie d'un moufle, dont l'autre poulie coopère avec une cordelette comportant une extrémité fixe.Similarly, there is a Swiss patent N ° 367,452 of April 19, 1958 which describes a double lift armor mechanism produced in the form of two hooks joined by a cord which passes, as in the French patent, around a pulley a block, the other pulley of which cooperates with a cord having a fixed end.

Pour réaliser une mécanique d'armure à trois positions, il faut utiliser deux systèmes à deux crochets dont les secondes poulies des moufles sont entourées par une cordelette à extrémités fixes et qui encercle la première poulie d'un troisième moufle dont l'autre poulie est encerclée par un fil d'arcade à une extrémité fixe.To make a three-position armor mechanism, two systems with two hooks must be used, the second pulley blocks of the mittens are surrounded by a cord with fixed ends and which encircles the first pulley with a third muffle, the other pulley of which is encircled by an arch wire at a fixed end.

On a décrit dans BE-A-529 019 une mécanique d'armure à trois positions dont l'arcade d'un crochet passe autour d'une poulie folle montée sur un axe fixe puis sur une poulie folle d'un moufle dont l'autre poulie est déplacée par un crochet voisin.We have described in BE-A-529 019 a three-position armor mechanism, the arch of a hook of which passes around a mad pulley mounted on a fixed axis and then on a mad pulley of a block, the another pulley is moved by a neighboring hook.

Les mécaniques d'armure à trois positions décrites dans les brevets antérieurs comportent certains inconvénients en ce qui concerne le guidage vertical des différents moufles. Ces derniers ont tendances à se déplacer horizontalement lors des différentes courses effectuées, si bien qu'on doit prévoir des guidages appropriés dont le prix de revient est élevé et qui compliquent considérablement la structure de la mécanique.The three-position armor mechanics described in the prior patents have certain drawbacks with regard to the vertical guidance of the various mittens. The latter tend to move horizontally during the various races carried out, so that it is necessary to provide suitable guides whose cost is high and which considerably complicate the structure of the mechanics.

C'est à ces inconvénients qu'entend spécialement remédier la présente invention.It is to these drawbacks that the present invention especially intends to remedy.

La mécanique d'armure à trois positions suivant l'invention est caractérisée en ce qu'elle comprend :

  • deux dispositifs voisins de formation de la foule en soi connus et comportant chacun deux crochets mobiles verticalement sous l'effet de couteaux qui se déplacent en opposition, suivant un mouvement de va-et-vient, ces crochets sont réunis par une cordelette passant autour d'une des poulies d'un moufle ;
  • une poulie montée folle sur un axe fixe par rapport au bâti de la mécanique ;
  • et un cordon dont l'une des extrémités est ancrée au bâti de la mécanique et qui entoure successivement la seconde poulie du moufle du premier dispositif, puis la poulie folle, ensuite la seconde poulie du moufle du second dispositif, la seconde extrémité dudit cordon étant associée à un collet auquel est accrochée au moins une lisse.
The three-position armor mechanics according to the invention is characterized in that it comprises:
  • two neighboring crowd-forming devices known per se and each comprising two hooks movable vertically under the effect of knives which move in opposition, following a back-and-forth movement, these hooks are joined by a cord passing around 'one of the pulleys of a mitten;
  • a pulley mounted idly on a fixed axis relative to the mechanical frame;
  • and a cord, one end of which is anchored to the mechanical frame and which successively surrounds the second pulley of the muffle of the first device, then the idler pulley, then the second pulley of the muffle of the second device, the second end of said cord being associated with a collar to which at least one stringer is attached.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 à 3 illustrent l'ensemble des éléments d'une mécanique d'armure à crochets suivant l'invention, respectivement en position basse, intermédiaire et haute du collet de l'arcade.
  • Fig. 4 est une vue semblable à celle de fig. 1, mais illustrant une variante préférée de l'invention.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 to 3 illustrate all the elements of a mechanical armor with hooks according to the invention, respectively in the low, intermediate and high position of the collar of the yoke.
  • Fig. 4 is a view similar to that of FIG. 1, but illustrating a preferred variant of the invention.

On a représenté en fig. 1 deux dispositifs de formation de la foule A et B comportant chacun deux crochets mobiles 1 et 2 destinés à coopérer avec deux cadres de griffes 3 et 4 portant chacun des couteaux 3a et 4a.There is shown in fig. 1 two crowd formation devices A and B each comprising two movable hooks 1 and 2 intended to cooperate with two claw frames 3 and 4 each carrying knives 3 a and 4 a .

Les crochets 1 et 2 sont constitués par une branche principale 1a et 2a rectiligne dont l'extrémité supérieure est pourvue d'un bec 1b et 2b, tandis que son extrémité inférieure est recourbée pour former une seconde branche 1c, 2c verticale, munie d'un crochet 1d, 2d coopérant respectivement avec une barre 5a et 5b de la grille 5 constituant la planche de fond.The hooks 1 and 2 are constituted by a main branch 1 a and 2 a straight whose upper end is provided with a spout 1 b and 2 b , while its lower end is curved to form a second branch 1 c , 2 c vertical, provided with a hook 1 d , 2 d cooperating respectively with a bar 5 a and 5 b of the grid 5 constituting the bottom board.

Chacune des branches 1a, 2a des crochets 1 et 2 passe dans l'anneau d'une aiguille de presse référencée 6a, 6b et 7a, 7b qui à la manière connue permet de faire échapper les becs 1b, 2b aux couteaux 3a, 4a quand on ne désire pas que les crochets soient saisis par ces couteaux.Each of the branches 1 a , 2 has hooks 1 and 2 passes through the ring of a press needle referenced 6 a , 6 b and 7 a , 7 b which in the known manner allows the spouts 1 b to escape, 2 b to the knives 3 a , 4 a when you do not want the hooks to be gripped by these knives.

Les liaisons 1e, 2e des branches 1a, 1c respectivement 2a, 2c des crochets 1 et 2 sont reliées par une cordelette 8 passant autour d'une poulie 9a d'un moufle 9.The connections 1 e , 2 e of the branches 1 a , 1 c respectively 2 a , 2 c of the hooks 1 and 2 are connected by a cord 8 passing around a pulley 9 a of a block 9.

Entre les deux dispositifs A et B on a prévu une poulie 10 tournant librement autour d'un axe 11 solidaire du bâti 12 de la mécanique d'armure. Les secondes poulies 9b des deux moufles 9 des deux dispositifs A et B, et la poulie 10 sont entourées par une autre cordelette ou arcade 13 dont l'une des extrémités 13a est attachée à un point fixe 12a du bâti 12, tandis que son autre extrémité 13b porte un mousqueton 14 constituant le collet auquel au moins une lisse 15 est fixée.Between the two devices A and B there is provided a pulley 10 freely rotating about an axis 11 secured to the frame 12 of the armor mechanism. The second pulleys 9b of two flasks 9 of the two devices A and B, and the pulley 10 are surrounded by another or arcade cord 13 whose one end 13a is attached to a fixed point 12 a of the frame 12, while that its other end 13 b carries a carabiner 14 constituting the collar to which at least one heald 15 is attached.

On réalise ainsi un double mouflage permettant d'obtenir les trois positions recherchées du collet 14, soit une position basse correspondant à la position inférieure des fils de chaîne (fig. 1), une position horizontale ou intermédiaire de ceux-ci (fig. 2), et une position haute ou supérieure de ces fils (fig. 3).A double hauling is thus carried out, making it possible to obtain the three desired positions of the collar 14, that is to say a low position corresponding to the lower position of the warp threads (fig. 1), a horizontal or intermediate position of these (fig. 2 ), and an upper or upper position of these wires (fig. 3).

Lorsque les fils de chaîne doivent être à la position basse (fig. 1), les branches 1a des dispositifs A et B sont pressées de manière que le couteau 4a n'accroche pas les becs 1b correspondants quand le cadre de griffes 4 monte. De même, les crochets 2 sont pressés pour que leur bec 2b ne soit pas entraîné par le couteau 3a correspondant au cadre de griffes 3 lorsqu'il s'élève après s'être abaissé. Ainsi, le collet 14 demeure en position basse et tous les crochets 1d, 2d des dispositifs A et B reposent sur les barres 5a, 5b de la grille 5.When the warp son should be in the lowered position (fig. 1), the arms 1a of the devices A and B are pressed so that the knife 4 has not grip the spouts 1b when the corresponding part of claws 4 mounts. Similarly, the hooks 2 are pressed so that their beak 2 b is not driven by the knife 3 a corresponding to the frame of claws 3 when it rises after being lowered. Thus, the collar 14 remains in the low position and all the hooks 1 d , 2 d of the devices A and B rest on the bars 5 a , 5 b of the grid 5.

La position moyenne représentée en fig. 2 est réalisé par le fait que l'on presse alternativement les branches 1a, 2a des crochets 1 et 2 du dispositif A, afin que les crochets 1d, 2d se trouvent en appui contre les barres 5a, 5b de la grille 5. Au contraire, les becs 1b, 2b des crochets du dispositif B restent en prise avec les couteaux 3a, 4a pendant le mouvement de va-et-vient des cadres de griffes 3 et 4.The average position shown in fig. 2 is realized in that one presses alternately the branches 1a, 2a of the hooks 1 and 2 of the device A, so that the hooks 1 d, 2 d are in abutment against the bars 5a, 5b of the grid 5. On the contrary, the beaks 1 b , 2 b of the hooks of the device B remain in engagement with the knives 3 a , 4 a during the back-and-forth movement of the claw frames 3 and 4.

Enfin, si le collet 14 doit venir en position haute (fig. 3), on laisse les becs 1b, 2b des quatre crochets 1 et 2 des dispositifs A et B en prise avec les couteaux 3a, 4a des deux cadres de griffes 3 et 4.Finally, if the collar 14 is to come in the high position (fig. 3), the beaks 1 b , 2 b of the four hooks 1 and 2 of the devices A and B are left in engagement with the knives 3 a , 4 has the two frames of claws 3 and 4.

Bien entendu, la disposition précédente peut aussi s'appliquer à une mécanique d'armure du genre de celle décrite dans le brevet français N° 2 587 045 du 6 septembre 1985 de la présente demanderesse.Of course, the above provision can also apply to an armor mechanism of the kind described in French patent No. 2,587,045 of September 6, 1985 of the present plaintiff.

On a représenté en fig. 4 un module 16 comportant une multiplicité de cloisons verticales 16a, 16b etc.., entre chacune desquelles se trouvent des dispositifs de formation de la foule A, B, C, D.., constitués chacun par deux crochets 17, 18 reliés par un cordon 19 entourant la première poulie 20a d'un moufle 20 guidé entre les cloisons considérées.There is shown in fig. 4 a module 16 comprising a multiplicity of vertical partitions 16 a , 16 b etc., between each of which are crowd-forming devices A, B, C, D .., each constituted by two hooks 17, 18 connected by a cord 19 surrounding the first pulley 20 a of a block 20 guided between the partitions considered.

Ces crochets 17, 18 se déplacent verticalement par l'intermédiaire de couteaux disposés sur des cadres de griffes, non représentés, et animés d'un mouvement de va-et-vient. Des éléments de retenue associés à des électro-aimants sont susceptibles de retenir les crochets mobiles 17, 18 en position haute. On ne reviendra pas en détail sur une telle stucture conforme au brevet français N° 2 587 045.These hooks 17, 18 move vertically by means of knives arranged on claw frames, not shown, and driven back and forth. Retaining elements associated with electromagnets are capable of retaining the movable hooks 17, 18 in the high position. We will not go into detail on such a structure in accordance with French Patent No. 2,587,045.

Conformément à l'invention, l'on a prévu une poulie folle 21 dont l'axe de rotation 21a est fixé sur une paroi horizontale 16c du module 16. Les secondes poulies 20b des moufles 20 de deux dispositifs A et B du module 16 et la poulie folle 21 sont entourées par une cordelette ou arcade 22 dont l'une des extrémités 22a est ancrée à un point fixe 16d du module, tandis que l'autre extrémité 22b porte un mousqueton 23 constituant le collet auquel au moins une lisse 24 est fixée.In accordance with the invention, an idler pulley 21 is provided, the axis of rotation 21 a of which is fixed to a horizontal wall 16 c of the module 16. The second pulleys 20 b of the mittens 20 of two devices A and B of the module 16 and the idler pulley 21 are surrounded by a cord or arch 22, one of the ends 22 a of which is anchored to a fixed point 16 d of the module, while the other end 22 b carries a carabiner 23 constituting the collar to which at least one heald 24 is attached.

On obtient ainsi un double mouflage permettant de réaliser les trois positions décrites précédement mais appliqué à un module décrit dans le brevet français 2 587 045 au nom de la Demanderesse et qui ne nécessite aucune pièce de guidage supplémentaire par rapport à celles d'un module standard, de sorte qu'une mécanique ainsi réalisée est économique et d'une grande simplicité de fabrication et d'entretien.A double hauling is thus obtained making it possible to achieve the three positions described above but applied to a module described in French patent 2,587,045 in the name of the Applicant and which does not require any additional guide part compared to those of a standard module , so that a mechanical thus produced is economical and very simple to manufacture and maintain.
