BROCHE DOUBLE TORSION PERFECTIONNEE POUR LE RETORDAGE OU
LE CABLAGE DE FILS.PERFECTED DOUBLE TORSION PIN FOR TWISTING OR
WIRING WIRING.
La présente invention concerne un perfectionnement apporté aux broches double torsion utilisées dans l'industrie textile pour réaliser le retordage (torsion communiquée à un seul fil élémentaire) ou le câblage (torsion et assemblage de plusieurs fils en une seule opération). The present invention relates to an improvement made to the double twist pins used in the textile industry for carrying out twisting (twisting imparted to a single elementary thread) or wiring (twisting and assembling of several threads in a single operation).
La figure 1 illustre, de manière schématique et vue de côté, la structure et le fonctionnement des machines de moulinage qui permettent de réaliser soit une opération de retordage sur un seul fil (partie droite référencée D), soit une opération de "câblage" de deux fils (partie gauche référencée G). FIG. 1 illustrates, schematically and seen from the side, the structure and the functioning of the molding machines which make it possible to carry out either a twisting operation on a single wire (right part referenced D), or a "wiring" operation of two wires (left part referenced G).
Dans les deux cas, l'organe essentiel de la machine est constitué par une broche double torsion, ensemble désigné par la référence générale (I), et qui comporte essentiellement
- un arbre vertical (2), entraîné en rotation par exemple par un système tangentiel à courroies (exemple représenté à la figure 1) ou par tout autre moyen équivalent, tel que par exemple un moteur individuel, et qui est maintenu sur le bâti B du métier par l'intermédiaire d'un palier ;
- un porte-enroulement (3) monté libre en rotation à l'extrémité de l'arbre (2) et maintenu fixe par rapport à celui-ci, par exemple à l'aide de moyens d'immobilisation magnétiques, ledit porte-enroulement étant destiné à recevoir une bobine ou gateau (4) de fil à tordre ;;
- un organe de renvoi (5) dit "plateau tournant", rotatif, disposé en dessous du porte-enroulement, et qui présente un canal latéral (6) pour le passage du fil. In both cases, the essential organ of the machine is constituted by a double twist spindle, assembly designated by the general reference (I), and which essentially comprises
- A vertical shaft (2), driven in rotation for example by a tangential belt system (example shown in Figure 1) or by any other equivalent means, such as for example an individual motor, and which is held on the frame B of the trade through a landing;
- a winding holder (3) mounted free to rotate at the end of the shaft (2) and kept fixed relative to the latter, for example using magnetic immobilization means, said winding holder being intended to receive a spool or cake (4) of twisting thread;
- A return member (5) called "rotating plate", rotating, arranged below the winding holder, and which has a lateral channel (6) for the passage of the wire.
Dans de tels ensembles, le fil F qui sort au travers de l'oeillet (6) du plateau rotatif (5), forme un ballon qui entoure les organes précités, puis passe dans un élément de guidage (7) disposé dans le prolongement de l'axe de la broche avant d'être renvidé de manière conventionnelle. In such assemblies, the wire F which comes out through the eyelet (6) of the rotary plate (5), forms a balloon which surrounds the abovementioned members, then passes through a guide element (7) arranged in the extension of the spindle axis before being returned in a conventional manner.
I1 a été proposé depuis fort longtemps, notamment en vue d'augmenter les vitesses et de diminuer la puissance consommée tout en ayant des entraxes réduits entre deux broches consécutives, d'entourer l'enroulement de fil (4) par un pot ou manchon (9), et ce sur toute sa hauteur. I1 has been proposed for a very long time, in particular with a view to increasing the speeds and decreasing the power consumed while having reduced centers between two consecutive pins, to surround the winding of wire (4) by a pot or sleeve ( 9), and this over its entire height.
Si en cours de fonctionnement normal, la présence de tels pots ne pose aucun problème de fonctionnement, en revanche, lors de la mise en route, il se produit des frottements susceptibles de provoquer des casses. Un tel inconvénient se trouve amplifié pour les fils sensibles à la chaleur, tels que par exemple les fils à base de polypropylène. Par suite, les solutions proposées à ce jour pour faciliter l'opération de démarrage, consistent à diminuer autant que possible le coefficient de frottement soit par adjonction d'huile, soit en traitant superficiellement les pots. If during normal operation, the presence of such pots poses no operating problem, on the other hand, during start-up, there is friction which may cause breakage. Such a drawback is amplified for heat-sensitive yarns, such as, for example, yarns based on polypropylene. Consequently, the solutions proposed to date to facilitate the start-up operation consist in reducing the friction coefficient as much as possible either by adding oil, or by treating the pots superficially.
Ces solutions ne donnent cependant pas entière satisfaction. However, these solutions are not entirely satisfactory.
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, un perfectionnement simple, qui permet de résoudre l'ensemble de ces problèmes. However, we have found, and this is what is the subject of the present invention, a simple improvement, which makes it possible to solve all of these problems.
D'une manière générale, le perfectionnement selon l'invention qui permet de diminuer les risques de casse lors du lancement de l'installation, se caractérise en ce que la surface extérieure du pot situé à l'intérieur du ballon formé par le fil, présente une succession d'excroissances disposées au moins dans les zones susceptibles d'être en contact avec le ballon du fil ou proches de celui-ci lors du démarrage de la broche. In general, the improvement according to the invention which makes it possible to reduce the risk of breakage during the launching of the installation, is characterized in that the external surface of the pot situated inside the balloon formed by the wire, has a succession of growths arranged at least in the areas likely to be in contact with the ball of the wire or close to it when the spindle starts.
De telles excroissances peuvent être soit rapportées sur le pot après réalisation, soit formées directement avec ce dernier. Elles peuvent avoir différentes formes, mais se présentent avantageusement sous la forme de rampes disposées à intervalles réguliers. Such growths can either be added to the pot after completion, or formed directly with the latter. They can have different shapes, but are advantageously in the form of ramps arranged at regular intervals.
L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce aux exemples de réalisation donnés ci-après à titre indicatif mais non limitatif, et qui sont illustrés par les schémas annexés dans lesquels:
- la figure 1 illustre comme dit précédemment, la structure générale des machines textiles utilisant des broches double torsion ;
- la figure 2 est une vue schématique en élévation d'un pot réalisé conformément à l'invention utilisable sur de telles machines ;
- les figures 3 et 4 sont des vues de dessus montrant deux formes de réalisation d'excroissance à la surface périphérique du pot illustré à la figure 1.The invention and the advantages which it brings will however be better understood thanks to the exemplary embodiments given below for information but not limitation, and which are illustrated by the appended diagrams in which:
- Figure 1 illustrates as said above, the general structure of textile machines using double twist spindles;
- Figure 2 is a schematic elevational view of a pot made according to the invention usable on such machines;
- Figures 3 and 4 are top views showing two embodiments of protuberance on the peripheral surface of the pot illustrated in Figure 1.
En se reportant aux figures annexées, dans une broche double torsion (1) conforme à l'invention, la surface extérieure du pot (9) qui entoure l'enroulement de fil (4), comporte une série d'excroissances (10) disposées au moins dans les zones susceptibles d'être en contact avec le ballon du fil F lors du démarrage de ladite broche, zons en général situées au sommet (11) de la partie cylindrique dudit pot (9). De telles excroissances peuvent avoir diverses formes comme cela ressort des figures 3 et 4. Dans la forme de réalisation illustrée à la figure 3, le pot (9) qui entoure les pièces se trouvant à l'intérieur du ballon, est de forme cylindrique et les excroissances (10) sont au nombre de quatre et se présentent sous la forme de petites rampes de section plane (quelques millimètres d'épaisseur) et de forme triangulaire. Referring to the appended figures, in a double twist spindle (1) according to the invention, the outer surface of the pot (9) which surrounds the wire winding (4), comprises a series of protrusions (10) arranged at least in the zones likely to be in contact with the ball of the wire F during the start-up of said spindle, zones generally situated at the top (11) of the cylindrical part of said pot (9). Such protuberances can have various shapes as can be seen from FIGS. 3 and 4. In the embodiment illustrated in FIG. 3, the pot (9) which surrounds the parts located inside the ball, is cylindrical in shape and the protrusions (10) are four in number and are in the form of small ramps of planar section (a few millimeters thick) and of triangular shape.
I1 pourrait également être envisagé, comme cela ressort de la figure 4, d'avoir un ensemble entourant les éléments disposés à l'intérieur du ballon ayant une forme polygonale. Les excroissances (10), dans un tel cas, seront disposées aux extrémités de chaque côté de cet ensemble polygonal. I1 could also be envisaged, as emerges from Figure 4, to have an assembly surrounding the elements arranged inside the balloon having a polygonal shape. The protuberances (10), in such a case, will be arranged at the ends of each side of this polygonal assembly.
Grâce à une telle conception, lors du démarrage, le fil F, comme cela ressort notamment des figures 2 et 3, se trouve décollé de la position F1 à la position F2 par la présence des excroissances périphériques (10). Il a été constaté qu'en procédant de cette manière, on éliminait pratiquement toutes les casses qui se produisent lors d'une telle opération et qu'il était même possible de traiter sur de telles broches double torsion des fils pratiquement impossibles à traiter à ce jour sur un tel matériel, sauf à prendre des précautions particulières telles que notamment des fils de polypropylène. Thanks to such a design, during start-up, the wire F, as is apparent in particular from FIGS. 2 and 3, is detached from position F1 to position F2 by the presence of the peripheral protuberances (10). It has been found that by proceeding in this way, practically all the breakages which occur during such an operation are eliminated and it is even possible to treat on such double twist pins wires which are practically impossible to treat at this point. day on such material, except to take special precautions such as in particular polypropylene threads.
Selon l'invention, les excroissances périphériques peuvent être soit rapportées soit former partie intégrante de la surface extérieure du pot (9). Elles peuvent être métalliques, en plastique, à base de matériau composite, en céramique. According to the invention, the peripheral protuberances can either be added or form an integral part of the external surface of the pot (9). They can be metallic, plastic, based on composite material, ceramic.
