Description

On sait que pour ouvrir le pas de la nappe des fils de chaîne d'un métier à tisser on utilise une mécanique destinée à lever un certain nombre de ces fils tout en laissant les autres à leur niveau inférieur de manière à permettre le passage d'une duite.We know that to open the pitch of the web of warp threads in a weaving loom, we use a mechanism intended to lift a certain number of these threads while leaving the others at their lower level so as to allow the passage of a pick.

Les dispositifs pour la formation de la foule sont généralement réalisés au moyen d'une mécanique d'armure comportant des crochets qui sont élevés et abaissés par des cadres de griffes, une sélection à partir d'un carton étant faite pour que les crochets soient saisis ou non par lesdits cadres de griffes.The devices for forming the crowd are generally produced by means of an armor mechanism comprising hooks which are raised and lowered by claw frames, a selection from a cardboard being made so that the hooks are grasped or not by said claw frames.

Il existe aussi des systèmes suivant lesquels chaque arcade est associée à la première poulie d'un palonnier qui comporte une seconde poulie entourée par un organe funiculaire dont les extrémités sont solidaires de deux crochets qui de manière continuelle sont déplacés verticalement de manière alternative en sens inverses au moyen de dispositifs appropriés tels que des couteaux. Lorsqu'on veut élever une arcade l'un des crochets mobiles est saisi, à son point mort haut, par un crochet de retenue généralement actionné par un électro-aimant. Un tel dispositif est décrit dans la demande de brevet allemand 2 204 815 retirée depuis Juin 1974. Les différents éléments des dispositifs pour la formation de la foule du genre décrit dans cette demande de brevet sont libres dans l'espace, ce qui entraîne un nombre élevé d'inconvénients. Tout d'abord, les crochets mobiles associés aux extrémités de l'élément funiculaire se trouvent à l'état isolé, de telle sorte que si une arcade se rompt, son remplacement est très difficile à effectuer et ceci d'autant plus qu'elle se trouve éloignée du bord du dispositif en question.There are also systems according to which each arch is associated with the first pulley of a lifting beam which comprises a second pulley surrounded by a funicular member whose ends are integral with two hooks which are continuously moved vertically alternately in opposite directions by means of suitable devices such as knives. When one wants to raise an arch one of the movable hooks is gripped, at its top dead center, by a retaining hook generally actuated by an electromagnet. Such a device is described in the German patent application 2 204 815 withdrawn since June 1974. The various elements of the devices for the formation of the crowd of the kind described in this patent application are free in space, which results in a number high drawbacks. First of all, the movable hooks associated with the ends of the funicular element are in an isolated state, so that if an arch is broken, its replacement is very difficult to perform and this all the more so since it is far from the edge of the device in question.

On constate en outre que le palonnier, c'est-à-dire le système à deux poulies dont l'une est entourée par l'élément funiculaire assurant la liaison entre les deux crochets mobiles, tandis que l'autre coopère avec l'arcade, est soumis à des mouvements parasites. On observe très souvent un mouvement pendulaire du palonnier et une tendance à la rotation. Ces différents inconvénients ont entraîné une limitation du nombre d'arcades sur les machines à grande vitesse connues.We also note that the lifting beam, that is to say the system with two pulleys, one of which is surrounded by the funicular element ensuring the connection between the two movable hooks, while the other cooperates with the yoke , is subject to parasitic movements. We very often observe a pendulum movement of the spreader and a tendency to rotation. These various drawbacks have led to a limitation in the number of arches on known high-speed machines.

Là encore, une rupture de l'élément funiculaire entraîne une chute du palonnier et de son arcade.Again, a rupture of the funicular element causes a fall of the lifter and its arch.

Les perfectionnements qui font l'objet de la présente invention visent à remédier aux inconvénients précités et à permettre la réalisation d'un dispositif pour la formation de la foule d'un métier à tisser qui puisse comprendre un grand nombre de systèmes de levée des fils de chaîne.The improvements which are the subject of the present invention aim to remedy the aforementioned drawbacks and to allow the production of a device for training the crowd in a weaving loom which may include a large number of yarn lifting systems. chain.

A cet effet, le dispositif suivant l'invention est esentiellement caractérisé en ce que les éléments de chaque système, c'est-à-dire les crochets de retenue avec leur dispositif de sélection, les crochets mobiles, et le palonnier sont disposés enfilé entre deux cloisons verticales reliées l'une avec l'autre de manière à former un ensemble compact et autonome.To this end, the device according to the invention is essentially characterized in that the elements of each system, that is to say the retaining hooks with their selection device, the movable hooks, and the lifter are arranged threaded between two vertical partitions connected to each other so as to form a compact and autonomous assembly.

Suivant une réalisation particulièrement avantageuse, on assemble côte-à-côte un certain nombre d'ensembles de manière à constituer un module que l'on peut facilement extraire ou remettre en place en cas d'incident à la place de n'importe quel autre du fait qu'il est pré-réglé.According to a particularly advantageous embodiment, a number of assemblies are assembled side by side so as to constitute a module which can be easily removed or replaced in the event of an incident in place of any other. because it is preset.

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 est une vue schématique illustrant un dispositif pour la formation de la foule d'un métier à tisser réalisé sous la forme d'un module établi conformément à l'invention et destiné à la commande de deux lisses seulement.
  • Fig. 2 à 5 illustrent le fonctionnement usuel d'un dispositif pour la formation de la foule dont chaque arcade est associée à un élément funiculaire muni de deux crochets à mouvement alternatif vertical.

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 is a schematic view illustrating a device for training the crowd of a weaving loom produced in the form of a module established in accordance with the invention and intended for the control of only two heddles.
  • Fig. 2 to 5 illustrate the usual operation of a device for training the crowd, each arcade of which is associated with a funicular element provided with two hooks with vertical reciprocating movement.
  • Fig. 6 is a cross section showing the arrangement of the elements of each arcade control system between two separating partitions.
  • Fig. 7 shows in perspective a module established in accordance with the invention.

On a illustré schématiquement en fig. 1 une nappe de fils de chaîne 1 disposée sur un métier à tisser et qui provient d'une ensouple 2. Chaque fil de chaîne passe dans l'oeillet 3a d'une lisse 3 destinée à ouvrir le pas pour permettre le passage d'une duite en vue de constituer un tissu qui s'enroule sur une bobine 4. Dans l'exemple représenté on suppose qu'il n'existe que deux lisses 3, ou que deux groupes de lisses, les unes étant en position élevée et les autres en position basse. C'est ainsi que l'on a référencé 3' la lisse en position basse et 3 celle en position haute. Les extrémités inférieures de chaque lisse sont reliées au bâti par un ressort de traction 5, tandis que leurs extrémités supérieures sont solidaires chacune d'une arcade 6. Les arcades sont élevées et abaissées au moyen d'un dispositif pour la formation de la foule référencé 7.Schematically illustrated in FIG. 1 a layer of warp threads 1 placed on a loom and which comes from a beam 2. Each warp thread passes through the eyelet 3a of a heddle 3 intended to open the pitch to allow the passage of a pick in order to constitute a fabric which is wound on a spool 4. In the example shown, it is assumed that there are only two heddles 3, or only two groups of heddles, one being in the raised position and the other in the low position. This is how we referenced 3 'the beam in the low position and 3 that in the high position. The lower ends of each stringer are connected to the frame by a tension spring 5, while their upper ends are each secured to an arcade 6. The arches are raised and lowered by means of a device for forming the crowd referenced 7.

Le dispositif pour la formation de la foule 7 est dans le cas de la présente invention constitué par un organe funiculaire 8 à chacune des extrémités duquel est associé un crochet 9. Ces derniers comportent un bec latéral coopérant avec un couteau 10 animé d'un mouvement alternatif vertical comme cela est bien connu. L'élément funiculaire 8 passe autour de la première poulie 11 d'un palonnier 12 dont la seconde poulie 13 est entourée par une arcade 6. L'extrémité de celle-ci opposée à celle qui est reliée à la vis 3 est ancrée à un point fixe 14 du bâti de la machine. La partie supérieure du dispositif 7 est pourvue de crochets de retenue réalisés sous la forme de lames flexibles 15 associées à la manière en soi connue à un électro-aimant unique 16 destiné à faire varier la position des lames de manière que ces dernières soient déplacées vers le centre lorsque l'électro-aimant est excité afin que leurs extrémités recourbées 15a puissent saisir l'un ou l'autre ou les deux crochets 9.The device for forming the crowd 7 is in the case of the present invention constituted by a funicular member 8 at each end of which is associated a hook 9. The latter comprise a lateral beak cooperating with a knife 10 animated by a movement vertical alternative as is well known. The funicular element 8 passes around the first pulley 11 of a spreader 12 whose second pulley 13 is surrounded by an arch 6. The end of the latter opposite to that which is connected to the screw 3 is anchored to a fixed point 14 of the machine frame. The upper part of the device 7 is provided with retaining hooks produced in the form of flexible blades 15 associated in the known manner with a single electromagnet 16 intended to vary the position of the blades so that the latter are moved towards the center when the electromagnet is energized so that their curved ends 15a can grip one either or both hooks 9.

C'est ainsi qu'en fig. 2, l'éléctro-aimant 16 n'est pas alimenté, de telle sorte que les crochets 9 s'élèvent et s'abaissent sans être saisis par les lames recourbées 15 de manière que le fil de chaîne correspondant reste à sa position basse. On a illustré en fig. 3 la position inverse des crochets mobiles qui ne change rien au positionnement de la lisse et du fil de chaîne correspondant puisque le palonnier reste en position stable.Thus in fig. 2, the electromagnet 16 is not supplied, so that the hooks 9 rise and fall without being gripped by the curved blades 15 so that the corresponding warp wire remains in its low position. Illustrated in fig. 3 the reverse position of the movable hooks which does not change the positioning of the arm and the corresponding warp thread since the lifter remains in the stable position.

Si à la position du crochet mobile de fig. 3 l'électro-aimant 16 est excité, les deux lames sont attirées de telle sorte que lors de la descente du couteau correspondant, le crochet considéré reste en position haute, si bien que la lame 10 redescend à vide. Lors de la montée de l'autre lame, on va provoquer l'élévation du palonnier 12 et celle de l'arcade et de la lisse considérée pour arriver à la position de fig. 4 dans laquelle les deux crochets mobiles restent en position haute de sorte que le fil de chaîne correspondant demeure soulevé en position de pas ouvert.If at the position of the movable hook of fig. 3 the electromagnet 16 is excited, the two blades are attracted so that during the descent of the corresponding knife, the hook considered remains in the high position, so that the blade 10 descends empty. During the rise of the other blade, the lifting beam 12 will be raised and that of the yoke and of the beam considered to arrive at the position of FIG. 4 in which the two movable hooks remain in the high position so that the corresponding warp thread remains raised in the open step position.

Pour redescendre le fil de chaîne à partir de sa position haute, on coupe l'aiimentation de l'électro-aimant, de telle sorte que les deux lames s'écartent de son noyau. L'un des crochets est saisi par le premier couteau qui arrive à son niveau et provoque sa descente tandis que l'autre reste accroché à la lame recourbée 15. Lorsque l'autre couteau arrive au niveau du crochet resté en haut, il le décroche de l'extrémité recourbée 15a de la lame 15 de telle sorte qu'on en revient à la position illustrée en fig. 2 sur laquelle on voit le crochet associé par son bec latéral au couteau 10.To lower the chain wire from its high position, the power supply to the electromagnet is cut off, so that the two blades move away from its core. One of the hooks is gripped by the first knife which arrives at its level and causes it to descend while the other remains attached to the curved blade 15. When the other knife arrives at the hook which remains at the top, it unhooks it from the curved end 15a of the blade 15 so that it returns to the position illustrated in FIG. 2 on which we see the hook associated by its side beak with the knife 10.

Il n'est pas utile de décrire plus avant le fonctionnement d'un tel dispositif pour la formation de la foule qui est bien connu dans la pratique.It is not useful to describe further the operation of such a device for training the crowd which is well known in practice.

Pour la facilité de la compréhension on appellera dans les présentes un système l'ensemble des éléments de commande d'une arcade, c'est-à-dire l'électro-aimant 16, les deux lames élastiques recourbées 15, les deux crochets mobiles 9 avec leur élément funiculaire 8 ainsi que le palonnier 12.For ease of understanding, a system will be referred to herein as all of the control elements of an arch, that is to say the electromagnet 16, the two bent elastic blades 15, the two movable hooks 9 with their funicular element 8 as well as the lifter 12.

Conformément à l'invention on place chaque système décrit ci-dessus entre deux cloisons séparatrices 17, reliées entre elles au niveau de leur tête 17a et de leur partie inférieure 17b. De plus des entretoises 17c assurent l'écartement de deux cloisons séparatrices voisines permettant le passage des crochets mobiles 9. On constitue ainsi un ensemble compact et autonome.In accordance with the invention, each system described above is placed between two dividing partitions 17, connected together at their head 17a and their lower part 17b. In addition, spacers 17c ensure the spacing of two adjacent dividing partitions allowing the passage of the movable hooks 9. This thus constitutes a compact and autonomous assembly.

On note que chaque cloison séparatrice 17 est pourvue d'une ouverture oblongue 17d constituant guidage pour le palonnier 12 qui comporte deux flasques 12a s'engageant chacune dans une ouverture 17d.It will be noted that each separating partition 17 is provided with an oblong opening 17d constituting a guide for the lifter 12 which comprises two flanges 12a each engaging in an opening 17d.

La tête 17a de chaque cloison séparatrice 17 est pourvue de deux épaulements 17e destinés à reposer sur deux traverses 18 du dispositif 7.The head 17a of each separating partition 17 is provided with two shoulders 17e intended to rest on two crosspieces 18 of the device 7.

On observe que la partie inférieure 17b des cloisons séparatrices 17 comporte une encoche 17f lui permettant de chevaucher une troisième traverse de retenue 19 ou vice-versa.It is observed that the lower part 17b of the dividing partitions 17 has a notch 17f allowing it to overlap a third retaining crosspiece 19 or vice versa.

Comme illustré en fig. 7 on assemble un certain nombre d'ensembles autonomes tel que celui illustré en fig. 6 de façon à constituer un module 20 comportant de manière non limitative par exemple six à dix ensembles. Le module supporte une plaquette 21 comportant le circuit d'alimentation des électro-aimants correspondants. Ladite plaquette est embrochée par rapport à des fiches complémentaires portées par des dispositifs 7 et qui n'on pas été représentés sur les dessins.As illustrated in fig. 7 a number of autonomous assemblies such as that illustrated in FIG. 6 so as to constitute a module 20 comprising, without limitation, for example six to ten assemblies. The module supports a plate 21 comprising the supply circuit for the corresponding electromagnets. Said plate is skewered with respect to complementary sheets carried by devices 7 and which have not been shown in the drawings.

De la façon dont il est conçu, chaque module 20 peut être extrait pour des raisons d'entretien ou de réparation de manière simple et en un temps très court. Il va de soi que la remise en place d'un module s'effectue dans les mêmes conditions en faisant coopérer ses moyens de retenue 17e, 17f avec les traverses 18, 19.As it is designed, each module 20 can be removed for maintenance or repair reasons in a simple manner and in a very short time. It goes without saying that the replacement of a module is carried out under the same conditions by making its retaining means 17e, 17f cooperate with the crosspieces 18, 19.

On observe en fig. 6 et 7 que l'extrémité de l'arcade 6 opposée à celle qui est associée à la lisse est engagée dans une entaille 17g ménagée dans la base de chaque cloison séparatrice afin de s'y coincer par exemple au moyen d'un embout surmoulé sur l'extrémité correspondante de la lisse.We observe in fig. 6 and 7 that the end of the arch 6 opposite to that which is associated with the heddle is engaged in a notch 17g formed in the base of each separating partition in order to be wedged therein for example by means of a molded end piece on the corresponding end of the arm.
