Description
L'invention a trait à un dispositif d'entraínement d'aiguilles de maillage pour métier à tisser à faucilles. L'invention a également trait à un métier à tisser équipé d'un tel dispositif.The invention relates to a training device mesh needles for a sickle loom. The invention also relates to an equipped loom such a device.
Dans le domaine des métiers à tisser à faucilles, il est connu d'utiliser, pour la formation des lisières des tissus ou rubans en cours de fabrication, des aiguilles dites de maillage qui opèrent par mouvement d'avance et de recul en synchronisme avec le mouvement des faucilles, ceci afin de crocheter le fil de trame amené par une faucille et le mailler avec la trame précédente. Ces aiguilles de maillage sont généralement pourvues d'un clapet et commandées par des dispositifs à cames et bielles qui doivent être réglés de façon précise afin de fixer l'amplitude et les positions extrêmes de la course de ces aiguilles. Ces dispositifs d'entraínement et de commande sont complexes et relativement peu fiables. Ils sont, en outre, coûteux et leur réglage est long et délicat, ce qui ne permet pas d'obtenir une précision et une répétitivité satisfaisantes du mouvement des aiguilles de maillage.In the field of sickle looms, it is is known to use, for the formation of selvedges fabrics or ribbons in the process of manufacture, needles so-called mesh which operate by movement in advance and recoil in synchronism with the movement of the sickles, this in order to crochet the weft thread brought by a sickle and mesh it with the previous frame. These needles mesh are usually provided with a flap and controlled by cam and link devices which must be precisely regulated in order to fix the amplitude and the extreme positions of the race of these needles. These training and control devices are complex and relatively unreliable. They are, in addition, expensive and their adjustment is long and delicate, which does not provide precision and repeatability satisfactory movement of the mesh needles.
C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau dispositif d'entraínement pour des aiguilles de maillage qui est aisément réglable et qui n'a pas tendance à se dérégler au cours du temps, alors que sa construction est plus simple que celle des dispositifs connus, ce qui lui confère une meilleure fiabilité.It is to these disadvantages that more particularly remedy the invention by proposing a new training device for the needles of mesh that is easily adjustable and does not tend to go wrong over time, while its construction is simpler than that of known devices, which gives it better reliability.
Dans cet esprit, l'invention concerne un dispositif d'entraínement d'aiguilles de maillage pour métier à tisser à faucilles qui comprend un actionneur rotatif électrique dont l'arbre de sortie est cinématiquement lié, par des moyens de transformation d'un mouvement rotatif en un mouvement translatif, à plusieurs aiguilles de maillages. In this spirit, the invention relates to a device training mesh needles for loom with sickles that includes an electric rotary actuator whose output shaft is kinematically linked, by means of transforming a rotary motion into a translational movement, with several meshing needles.
Grâce à l'invention, les réglages du mouvement des aiguilles de maillage peuvent être effectués de façon extrêmement rapide et précise en jouant sur les paramètres de commande de l'actionneur rotatif électrique. En outre, le fait de commander plusieurs aiguilles grâce à un même actionneur permet de limiter le nombre de composants du dispositif d'entraínement, ce qui diminue son coût et améliore sa fiabilité. Le dispositif de l'invention peut fonctionner à vitesse élevée, notamment plus élevée que les systèmes à bielles et cames de l'état de la technique, alors que son encombrement est réduit. Le mouvement linéaire des aiguilles de maillage parallèlement à la lisière du tissu ou du ruban en cours de tissage permet de faire des mailles moins hautes et de réduire la compensation nécessaire.Thanks to the invention, the adjustments of the movement of mesh needles can be made so extremely fast and accurate by playing on the parameters control of the electric rotary actuator. In addition, the fact of ordering several needles thanks to the same actuator makes it possible to limit the number of components of the drive device, which decreases its cost and improves its reliability. The device of the invention can operate at high speed, particularly higher than rod and cam systems of the state of the art, while its size is reduced. Movement linear needles mesh parallel to the edge of the fabric or ribbon being woven allows for make smaller stitches and reduce the necessary compensation.

- Les moyens de transformation de mouvement sont répartis selon la longueur ou la direction longitudinale de l'arbre précité et permettent d'entraíner chacun une aiguille de maillage. Dans ce cas, la position de ces moyens de transformation de mouvement le long de cet arbre est avantageusement réglable, ce qui permet un déplacement aisé des aiguilles de maillage dans le sens de la trame, donc un réglage de la largeur du tissu ou du ruban tissé.
- Selon un premier mode de réalisation, le dispositif comprend au moins un pignon entraíné en rotation par l'arbre précité et en prise avec une crémaillère solidaire d'une aiguille de maillage. Ce pignon est avantageusement monté coulissant à jeu réduit le long de l'arbre précité. Cet arbre peut avoir une section extérieure non circulaire, alors que le pignon est pourvu d'une ouverture de passage de l'arbre qui a un profil au moins en partie sensiblement complémentaire de sa section. On peut, par exemple, prévoir que l'arbre est cannelé, alors que le pignon a une ouverture centrale également cannelée.
- Selon un second mode de réalisation de l'invention, au moins un élément flexible est arrimé et partiellement enroulé autour de l'arbre, cet élément flexible étant solidarisé à une aiguille de maillage ou à un organe d'entraínement en translation d'une telle aiguille.
- Selon un troisième mode de réalisation de l'invention, l'arbre précité est équipé d'au moins un élément faisant saillie radialement, notamment de type bielle ou came, qui s'étend vers l'extérieur par rapport à l'arbre précité et qui est accouplé à l'une des aiguilles de maillage ou à un organe d'entraínement en translation d'une telle aiguille.
- Quel que soit le mode de réalisation, l'aiguille de maillage est avantageusement solidarisée de façon amovible sur la crémaillère ou sur son organe d'entraínement.
- The movement transformation means are distributed along the length or the longitudinal direction of the aforementioned shaft and allow each to drive a mesh needle. In this case, the position of these movement transformation means along this shaft is advantageously adjustable, which allows an easy movement of the mesh needles in the direction of the weft, so an adjustment of the width of the fabric or ribbon woven.
- According to a first embodiment, the device comprises at least one pinion driven in rotation by the aforementioned shaft and engaged with a rack integral with a mesh needle. This pinion is advantageously slidably mounted with reduced clearance along the aforementioned shaft. This shaft may have a non-circular outer section, while the pinion is provided with a passage opening of the shaft which has a profile at least partly substantially complementary to its section. One can, for example, provide that the shaft is fluted, while the pinion has a central opening also fluted.
- According to a second embodiment of the invention, at least one flexible element is stowed and partially wound around the shaft, this flexible element being secured to a mesh needle or to a drive member in translation of such a member. needle.
- According to a third embodiment of the invention, the aforementioned shaft is equipped with at least one radially projecting element, in particular of the connecting rod or cam type, which extends outwards with respect to the aforementioned shaft and which is coupled to one of the mesh needles or to a drive member in translation of such a needle.
- Whatever the embodiment, the mesh needle is advantageously secured in a detachable manner on the rack or on its drive member.
L'invention concerne également un métier à tisser à faucilles équipé d'un dispositif d'entraínement tel que précédemment décrit. Un tel métier est plus aisé à fabriquer, à régler et à entretenir que ceux de l'état de la technique et peut fonctionner à vitesse plus élevée.The invention also relates to a loom for sickles equipped with a training device such as previously described. Such a job is easier to to manufacture, regulate and maintain those of the State of the technique and can operate at higher speed.

Le métier à tisser M représenté partiellement à la figure 1 permet de tisser en parallèle plusieurs rubans R en croisant des fils de chaíne 1 et des fils de trame 2. Pour chaque ruban R, les fils de trame sont plus ou moins écartés les uns des autres en formant une foule F, cette foule étant, par exemple, obtenue au moyen d'un mécanisme de type Jacquard, connu en soi et non représenté.The loom M partially represented in the FIG. 1 makes it possible to weave several ribbons in parallel. by crossing warp yarns 1 and weft yarns 2. For each ribbon R, the weft threads are more or less spaced apart from each other by forming a crowd F, this crowd being, for example, obtained by means of a mechanism Jacquard type, known in itself and not shown.
Pour chaque ruban, le fil de trame 2 est fourni à
partir d'un dévidoir non représenté et introduit dans la
foule F au moyen d'une faucille 4 animée d'un mouvement de
rotation alternée F1 autour d'un axe X-X' sensiblement
vertical. Le fil de trame 2 passe dans un oeillet 41 ménagé
au voisinage de l'extrémité libre 42 de la faucille 4 dont
le mécanisme d'entraínement autour de l'axe X-X' n'est pas

dont l'arbre de sortie 7 est cannelé et centré sur un axe
géométrique Y-Y' globalement perpendiculaire à l'axe X-X'
et à la direction F3 d'avance des fils de chaíne. Sur
l'arbre 7 sont montés des pignons 8 en nombre égal au
nombre d'aiguilles 5 à entraíner, chacun de ces pignons
étant destiné à être en prise avec une crémaillère 9 sur
laquelle est rapportée une aiguille 5.To drive the three
En pratique, chaque crémaillère est pourvue d'un
logement 91 de réception d'une extrémité arrière 51 d'une
aiguille 5, ainsi que d'une vis 92 de blocage de cette
extrémité 51 dans ce logement 91. Ainsi, chaque aiguille 5
est solidarisée de façon amovible avec une crémaillère 9,
ce qui permet de procéder à un échange rapide et aisé d'une
ou plusieurs aiguilles 5 lors des opérations de maintenance
du métier M.In practice, each rack is provided with a
Comme il ressort plus particulièrement de la figure 2,
chaque pignon 8 est pourvu d'une ouverture centrale
cannelée 81 dont la géométrie est sensiblement
complémentaire des cannelures 71 de l'arbre 7, de façon à
permettre une solidarisation en rotation du pignon 8 avec
l'arbre 7 et un coulissement à jeu réduit du pignon 8 le
long de cet arbre, parallèlement à l'axe Y-Y', comme
