Description

La présente invention a trait à un perfectionnement apporté aux broches utilisées dans l'industrie textile, notamment pour le retordage des fils.The present invention relates to an improvement made to pins used in the textile industry, in particular for twisting the threads.

Les broches de retordage sont des dispositifs connus depuis fort longtemps et sont constituées essentiellement d'un arbre (ou fût de broche) monté libre en rotation sur le bâti de la machine par l'intermédiaire d'un palier approprié.Twisting pins are devices which have been known for a very long time and consist essentially of a shaft (or spindle barrel) mounted freely in rotation on the frame of the machine by means of an appropriate bearing.

Outre les broches dites "simple torsion" dans les­quelles le tube autour duquel est enroulé le fil est emmanché directement sur le fût de broche, et qui per­mettent donc, pour une rotation de ladite broche d'ob­tenir un tour de torsion sur le fil, il a été proposé depuis fort longtemps de réaliser des broches dites "à double torsion" qui, comme les broches précédentes, com­portent un fût vertical entraîné en rotation. Dans les deux cas, comme moyen d'entraînement en rotation, le système le plus répandu consiste dans l'utilisation d'une courroie sans fin, qui entraîne simultanément toutes les broches de la machine et qui est en contact tangentiel avec la base du fût de la broche.In addition to the so-called "simple twist" pins in which the tube around which the wire is wound is fitted directly onto the spindle barrel, and which therefore allow, for a rotation of said spindle to obtain a twist turn on the wire, has been proposed for a long time to make pins called "double twist" which, like the previous pins, have a vertical shaft driven in rotation. In both cases, as a means of rotary drive, the most widespread system consists in the use of an endless belt, which simultaneously drives all the spindles of the machine and which is in tangential contact with the base of the barrel. of the spindle.

Dans le domaine des broches de retordage à simple torsion, il a été proposé depuis fort longtemps, ainsi que cela ressort notamment du brevet français 650 239 et du brevet US-2 274 147, d'entraîner les broches indivi­duellement au moyen d'un moteur électrique. De très nom­breux perfectionnements à un tel système d'entraînement par moteur individuel ont été proposés. Parmi les solu­tions récentes, on peut citer celle faisant l'objet du brevet français 81 12 918 (publication :2 508 499) cor­respondant au brevet US 4 420 226 qui, par rapport aux solutions antérieures, présente l'avantage de permettre un amortissement très efficace des vibrations, d'abaisser le centre de gravité de l'ensemble par rapport au bâti support, d'être silencieuse, de pouvoir être facilement démontée, notamment lors d'une opération d'entretien.In the field of single-twist twisting pins, it has been proposed for a very long time, as is apparent in particular from French patent 650 239 and from patent US-2 274 147, to drive the pins individually by means of a motor. electric. Numerous improvements have been made to such an individual motor drive system. Among the recent solutions, one can cite that which is the subject of French patent 81 12 918 (publication: 2 508 499) corresponding to US patent 4 420 226 which, compared to previous solutions, has the advantage of allowing very effective vibration damping, of lowering the center of gravity of the together with respect to the support frame, to be silent, to be able to be easily disassembled, in particular during a maintenance operation.

Dans le domaine des broches double torsion qui sont d'une conception beaucoup plus complexe comparées à des broches simple torsion, l'entraînement au moyen d'un moteur individuel pose cependant encore un certain nom­bre de problèmes, notamment en ce qui concerne les faci­lités de démontage des éléments constituant "la partie textile" de tels ensembles, éléments qui sont constitués essentiellement d'un porte-enroulement concentrique à l'axe de la broche destinée à recevoir la bobine de fil à tordre, cet enroulement étant constitué essentielle­ment d'un axe fixe disposé selon l'axe mobile, d'une embase et d'un pot de protection emmanché sur ladite embase, d'un plateau de renvoi rotatif, solidaire de la broche proprement dite, situé dans un plan horizontal sous le porte-enroulement et des moyens d'immobilisation dudit porte-enroulement.In the field of double twist spindles which are of a much more complex design compared to single twist spindles, the drive by means of an individual motor however still poses a certain number of problems, in particular as regards the ease of dismantling of the elements constituting "the textile part" of such assemblies, elements which consist essentially of a winding holder concentric with the axis of the spindle intended to receive the spool of twisting yarn, this winding consisting essentially of a fixed axis disposed along the mobile axis, of a base and a protective pot fitted on said base, of a rotary deflection plate, integral with the spindle proper, located in a horizontal plane under the winding carrier and means for immobilizing said winding carrier.

Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, un perfectionnement apporté aux bro­ches double torsion, qui non seulement permet l'entraîne­ment desdites broches au moyen d'un moteur de commande individuel, mais également conduit à la réalisation d'un ensemble totalement démontable, la partie textile pouvant être séparée très facilement de la partie stator du mo­teur fixée sur le bâti de la machine.Now we have found, and this is what is the subject of the present invention, an improvement made to the double twist spindles, which not only allows the driving of said spindles by means of an individual control motor, but also leads when making a completely removable assembly, the textile part being able to be very easily separated from the stator part of the motor fixed to the frame of the machine.

D'une manière générale, l'invention concerne donc une broche de retordage à double torsion entraînée par un moteur électrique individuel dont le stator est fixé sur le bâti support de la machine et dont le rotor est solidaire du fût de la broche, un porte-enroulement fixe étant disposé dans le prolongement de ladite broche. La broche selon l'invention se caractérise en ce que le montage des organes fixes sur le bâti de la machine est réalisé par l'intermédiaire d'un manchon monté de manière élastique sur ledit bâti et qui est solidaire du carter du moteur, les roulements guidant et supportant les or­ganes mobiles de ladite broche étant montés à l'intérieur d'une douille intermédiaire, fixée de manière amovible à l'intérieur du manchon support.In general, the invention therefore relates to a twisting twist spindle driven by an individual electric motor, the stator of which is fixed to the support frame of the machine and the rotor of which is integral with the barrel of the spindle, a door -fixed winding being arranged in the extension of said spindle. The spindle according to the invention is characterized in that the mounting of the fixed members on the frame of the machine is carried out by means of a sleeve resiliently mounted on said frame and which is integral with the motor housing, the bearings guiding and supporting the movable members of said spindle being mounted inside an intermediate sleeve, removably fixed inside the support sleeve.

L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce à l'exemple de réalisation donné ci-après à titre indicatif, mais non limitatif et qui est illustré par les schémas annexés dans lesquels:

  • - la figure 1 est une vue en coupe de l'ensemble d'une broche double torsion conforme à l'invention uti­lisée lors d'une opération de câblage direct, c'est-à-­dire pour retordre deux fils élémentaires ensemble ;
  • - les figures 2 et 3 sont des vues partielles, agrandies par rapport à la figure 1, qui montrent plus en détail la structure de la broche conforme à l'inven­tion lorsqu'elle est démontée, la figure 2 correspondant aux éléments de la broche qui restent solidaires du bâti de la machine, alors que la figure 3 montre l'ensemble des organes qui constituent la partie textile de la bro­che.
The invention and the advantages which it brings will however be better understood thanks to the example of embodiment given below for information, but not limitation and which is illustrated by the appended diagrams in which:
  • - Figure 1 is a sectional view of the assembly of a double twist pin according to the invention used during a direct wiring operation, that is to say to twist two elementary son together;
  • - Figures 2 and 3 are partial views, enlarged with respect to Figure 1, which show in more detail the structure of the spindle according to the invention when it is dismantled, Figure 2 corresponding to the elements of the spindle which remain integral with the frame of the machine, while FIG. 3 shows all of the members which constitute the textile part of the spindle.

Il est bien entendu que cet exemple de réalisation n'est pas limitatif et que le même type de broche pour­rait être utilisé pour communiquer une torsion à un fil simple.It is understood that this exemplary embodiment is not limiting and that the same type of pin could be used to communicate a twist to a single wire.

Ainsi qu'on peut le voir sur les figures annexées, la broche double torsion réalisée conformément à l'in­vention est constituée essentiellement d'un ensemble monté sur le bâti (1) de la machine et qui se compose essentiellement d'un fût (2) destiné à être entraîné en rotation et au-dessus duquel sont montés les principaux organes constituant la partie textile de ladite broche. Ces organes sont constitués essentiellement d'un porte-­enroulement (3) fixe, pour une bobine de fil (4) montée sur une embase fixe (5) et autour duquel est monté un déflecteur (6). Un plateau rotatif (7) de renvoi, soli­daire du fût (2) de la broche verticale, est disposé en­dessous du porte-enroulement (3). Dans la forme de réali­sation illustrée à la figure 1 où la broche double tor­sion conforme à l'invention est utilisée pour réaliser une opération de câblage direct, un fil (F1) passe au travers du fût (2) de la broche et forme un ballon autour de l'ensemble décrit précédemment, le second fil (F2) provenant de la bobine (4) passant au travers d'un ten­deur (T) et les deux fils étant réunis en (8).As can be seen in the appended figures, the double twist spindle produced in accordance with the invention consists essentially of an assembly mounted on the frame (1) of the machine and which essentially consists of a barrel (2 ) intended to be rotated and above which are mounted the main members constituting the textile part of said spindle. These members essentially consist of a fixed winding carrier (3), for a coil of wire (4) mounted on a fixed base (5) and around which a deflector (6) is mounted. A revolving turntable (7), integral with the barrel (2) of the vertical spindle, is arranged below the winding holder (3). In the embodiment illustrated in Figure 1 where the double twist pin according to the invention is used to perform a direct wiring operation, a wire (F1) passes through the barrel (2) of the pin and forms a balloon around the assembly described above, the second wire (F2) coming from the spool (4) passing through a tensioner (T) and the two wires being joined together in (8).

L'entraînement en rotation des organes mobiles de la broche (représentés à la figure 3) et plus particu­lièrement du fût (2) est obtenu au moyen d'un moteur in­dividuel désigné par la référence générale (9). Ce mo­teur individuel est constitué essentiellement d'un sta­tor (10) et d'un rotor (11). Le stator (10) est monté sur le bâti (1) de la machine par l'intermédiaire d'un manchon (12) disposé à l'intérieur du corps du moteur. Ce manchon (12) est fixé au moyen de plots élastiques (13) sur le bâti (1). Le rotor (11) est, quant à lui, monté à l'extrémité du fût (2) de broche (voir figure 3).The rotational drive of the movable members of the spindle (shown in Figure 3) and more particularly of the barrel (2) is obtained by means of an individual motor designated by the general reference (9). This individual motor essentially consists of a stator (10) and a rotor (11). The stator (10) is mounted on the frame (1) of the machine by means of a sleeve (12) arranged inside the body of the motor. This sleeve (12) is fixed by means of elastic studs (13) on the frame (1). The rotor (11) is, in turn, mounted at the end of the spindle barrel (2) (see Figure 3).

Conformément à l'invention, le fût (2) de broche est monté à l'intérieur du manchon (12) fixe par l'in­termédiaire de roulements (14,15) qui sont montés à l'in­térieur d une douille intermédiaire (16) immobilisée à l'intérieur du manchon (12) au moyen d'une vis de blocage (17). Aux figures 2 et 3 où la broche conforme à l'inven­tion est montrée démontée, la vis de blocage (17) n'est pas représentée, seul l'axe (17a) selon lequel s'effectue la jonction entre les éléments étant schématisé. Une entretoise (18) et un écrou (19) disposés autour du fût (2) permettent d'assurer l'immobilisation du rotor (11) autour dudit fut.According to the invention, the spindle barrel (2) is mounted inside the fixed sleeve (12) by means of bearings (14,15) which are mounted inside an intermediate sleeve (16) immobilized inside the sleeve (12) by means of a locking screw (17). In Figures 2 and 3 where the spindle according to the invention is shown disassembled, the locking screw (17) is not shown, only the axis (17a) along which the junction between the elements is shown schematically. A spacer (18) and a nut (19) arranged around the barrel (2) make it possible to immobilize the rotor (11) around said barrel.

Un tel ensemble de conception particulièrement sim­ple présente comme avantage de pouvoir être démonté très facilement puisqu'il suffit, pour enlever tous les élé­ments formant la partie textile de la broche (et qui sont montrés à la figure 3), de dévisser la vis de blocage (17).Such an assembly of particularly simple design has the advantage of being able to be disassembled very easily since it suffices, to remove all the elements forming the textile part of the spindle (and which are shown in FIG. 3), to unscrew the locking screw (17).

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation décrit précédemment, mais elle en couvre toutes les variantes réalisées dans le même esprit.Of course, the invention is not limited to the embodiment described above, but it covers all the variants produced in the same spirit.
