Description

La présente invention concerne un perfectionnement apporté aux machines permettant de réaliser des câblés, c'est-à-dire des éléments textiles de grande longueur, obtenus par assemblage par torsion d'au moins deux fils élémentaires.The present invention relates to an improvement made to machines making it possible to produce cords, that is to say textile elements of great length, obtained by assembling by twisting at least two elementary threads.

D'une manière générale, et ainsi que cela ressort de la figure 1 annexée qui est une reproduction de la figure illustrant le FR-A-2 565 261 (correspondant à l'US-A-4 592 195), une machine de câblage est constituée d'une pluralité de positions de travail identiques, disposées côte à côte, chaque position comportant un ensemble analogue à une broche double torsion dévideuse (ensemble DT) permettant de réunir par torsion deux fils élémentaires (1,2).In general, and as is apparent from the appended FIG. 1 which is a reproduction of the figure illustrating FR-A-2,565,261 (corresponding to US-A-4,592,195), a wiring machine consists of a plurality of identical working positions, arranged side by side, each position comprising an assembly analogous to a double twist spindle reel (DT assembly) making it possible to join two elementary wires (1,2) by twist.

Dans une telle machine, le fil (1) prélevé d'une source d'alimentation non représentée, arrive à l'extrémité inférieure de la broche creuse (3) de l'ensemble DT et passe au travers d'un canal percé radialement dans un plateau rotatif (3a) de ladite broche. En raison de la rotation de cette broche, il subit une fausse torsion et il forme un ballon (1a) qui entoure la cuvette (3b) de la broche (3) de l'ensemble DT. A l'intérieur de la cuvette (3b), est disposée une bobine (4) du second fil (2). Ce second fil (2) passe au travers d'un dispositif de freinage (6), dénommé également "régulateur de tension" et qui est porté par le couvercle (3c) de la cuvette (3b). L'assemblage des fils (1) et (2) est obtenu par torsion au moyen d'un ensemble désigné par la référence générale (7), et communément appelé "tête de câblage" ou "régulateur de longueur".In such a machine, the wire (1) taken from a power source not shown, arrives at the lower end of the hollow spindle (3) of the DT assembly and passes through a channel drilled radially in a rotary plate (3a) of said spindle. Due to the rotation of this spindle, it undergoes a false twist and it forms a balloon (1a) which surrounds the bowl (3b) of the spindle (3) of the DT assembly. Inside the bowl (3b) is disposed a coil (4) of the second wire (2). This second wire (2) passes through a braking device (6), also called "voltage regulator" and which is carried by the cover (3c) of the bowl (3b). The assembly of the wires (1) and (2) is obtained by twisting by means of an assembly designated by the general reference (7), and commonly called "wiring head" or "length regulator".

L'invention porte plus particulièrement sur "la tête de câblage" ou "régulateur de longueur" (7) que comportent de telles installations ainsi que sur un nouveau type d'ensemble intégrant à la fois le régulateur de tension (6) (ou dispositif de freinage) et une telle tête de câblage ou régulateur de longueur (7) comme cela sera vu dans la suite de la description.The invention relates more particularly to the "wiring head" or "length regulator" (7) which such installations comprise as well as to a new type of assembly integrating both the voltage regulator (6) (or device braking) and such a wiring head or length regulator (7) as will be seen in the following description.

Après réunion par torsion des deux fils (1,2) à la sortie de la tête de câblage (7), le câblé formé (8) passe sur un dispositif (9) bloquant la remontée de torsion, puis, après passage éventuel autour d'un guide de renvoi (10), il est renvidé sur un système conventionnel désigné par la référence générale (11).After joining by twist of the two wires (1,2) at the outlet of the wiring head (7), the formed cable (8) passes over a device (9) blocking the rise in torsion, then, after possible passage around 'a reference guide (10), it is returned to a conventional system designated by the general reference (11).

D'une manière générale, à ce jour, les têtes de câblage (7) sont constituées essentiellement par un ensemble tournant monté dans un palier supérieur (12) et dont l'axe de rotation est confondu avec celui de la broche (3). Cet ensemble tournant comporte en général deux poulies (13,14) disposées sur un même axe transversal à celui de la broche (3) et angulairement solidaires l'une de l'autre. Les fils (1,2) sont enroulés autour de ces poulies (13,14), puis sont réunis au point de câblage proprement dit (15), et passent alors à l'intérieur d'un canal axial de l'ensemble tournant pour être amenés au système bloqueur de remontée de torsion. De telles têtes de câblage à poulies rotatives sont connues depuis fort longtemps et sont décrites notamment dans le FR-A-1 208 273 ainsi que dans le FR-A-1 202 572 qui décrit une autre forme de réalisation selon laquelle les deux poulies sont montées sur leur support selon un axe confondu avec l'axe de la broche, au lieu d'être montées sur un axe transversal à celui de la dite broche comme vu précédemment.In general, to date, the wiring heads (7) consist essentially of a rotating assembly mounted in an upper bearing (12) and whose axis of rotation coincides with that of the spindle (3). This rotating assembly generally comprises two pulleys (13,14) arranged on the same axis transverse to that of the spindle (3) and angularly integral with one another. The wires (1,2) are wound around these pulleys (13,14), then are brought together at the actual wiring point (15), and then pass inside an axial channel of the rotating assembly for be brought to the torsion ascent blocking system. Such wiring heads with rotary pulleys have been known for a very long time and are described in particular in FR-A-1 208 273 as well as in FR-A-1 202 572 which describes another embodiment according to which the two pulleys are mounted on their support along an axis coincident with the axis of the spindle, instead of being mounted on an axis transverse to that of said spindle as seen above.

Il convient de noter que dans de telles têtes de câblage ou régulateurs, l'entraînement en rotation peut être obtenu soit par le fil extérieur (1) formant le ballon (1a) soit, éventuellement, au moyen d'un moteur individuel permettant un synchronisme parfait.It should be noted that in such wiring heads or regulators, the rotary drive can be obtained either by the external wire (1) forming the balloon (1a) or, optionally, by means of an individual motor allowing synchronism perfect.

Dans tous les cas, l'un des principaux problèmes qui se posent est celui de communiquer des tensions très régulières aussi bien aux fils élémentaires qu'au câblé formé ainsi que d'avoir une inertie aussi faible que possible pour l'ensemble tournant. Par ailleurs, une telle tête de câblage doit pouvoir être entretenue facilement et permettre une mise en place aisée des fils autour des roulettes.In all cases, one of the main problems which arises is that of communicating very regular voltages both to the elementary wires and to the cable formed as well as having as low an inertia as possible for the rotating assembly. Furthermore, such a wiring head must be able to be easily maintained and allow easy installation of the wires around the rollers.

Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, une solution de conception particulièrement simple, qui permet non seulement de résoudre l'ensemble de ces problèmes, mais également autorise l'utilisation d'un tel ensemble régulateur sans poulie (ou roulette) de renvoi pour les fils élémentaires, une telle possibilité étant rendue possible par le fait que, grâce à l'invention, on supprime au maximum les points d'embarrage et de frottement des fils élémentaires lors de leur trajet et que, par ailleurs, le point de câblage des deux fils se trouve parfaitement positionné et stabilisé.Now we have found, and this is the subject of the present invention, a particularly simple design solution, which not only makes it possible to solve all of these problems, but also allows the use of such a regulator assembly without pulley (or caster) for returning the elementary wires, such a possibility being made possible by the fact that, thanks to the invention, the points of interlocking and friction of the elementary wires are eliminated as much as possible path and that, moreover, the wiring point of the two wires is perfectly positioned and stabilized.

Un tel résultat est obtenu conformément à l'invention en réalisant une tête de câblage se présentant sous la forme d'un ensemble amovible, pouvant être monté sur le bâti support de la machine par l'intermédiaire d'un palier permettant son entraînement en rotation, ledit ensemble comportant essentiellement un corps de forme générale cylindrique, présentant sur sa hauteur une fenêtre traversante dont les faces sont parallèles à la génératrice dudit cylindre, et qui comporte à son extrémité libre un plateau circulaire de plus grande dimension supportant deux oeillets de guidage :

  • l'un proche de son bord périphérique et à l'intérieur duquel passe le fil formant le ballon et qui entraîne l'ensemble en rotation lors de la formation du câblé,
  • l'autre, disposé à proximité ou confondu avec l'axe de rotation de l'ensemble, et à l'intérieur duquel passe le second fil provenant de la bobine d'alimentation montée à l'intérieur de la cuvette de la broche,
ces deux oeillets définissant avec l'entrée du canal de sortie du câblé de ladite tête de câblage un triangle rectangle, dont le grand côté de l'angle droit est situé sensiblement selon l'axe de rotation de ladite tête, le point de câblage des deux fils élémentaires étant stabilisé sur ce côté en un point intermédiaire entre les deux extrémités.Such a result is obtained in accordance with the invention by producing a wiring head in the form of a removable assembly, which can be mounted on the support frame of the machine by means of a bearing allowing it to be driven in rotation. , said assembly essentially comprising a body of generally cylindrical shape, having on its height a window through which the faces are parallel to the generator of said cylinder, and which comprises at its free end a circular plate of larger dimension supporting two guide eyelets:
  • one close to its peripheral edge and inside which passes the wire forming the balloon and which drives the whole in rotation during the formation of the cable,
  • the other, placed close to or coincident with the axis of rotation of the assembly, and inside which passes the second wire coming from the supply coil mounted inside the spindle cup,
these two eyelets defining with the entry of the cable outlet channel of said wiring head a right triangle, the long side of the right angle of which is situated substantially along the axis of rotation of said head, the wiring point of the two elementary wires being stabilized on this side at an intermediate point between the two ends.

Au sens de la présente invention, l'expression "triangle rectangle", désigne aussi bien un véritable triangle rectangle qu'un triangle dont l'angle au sommet n'est pas strictement égal à 90°, mais voisin d'un tel angle.Within the meaning of the present invention, the expression "right triangle" denotes both a true right triangle and a triangle whose angle at the top is not strictly equal to 90 °, but close to such an angle.

Un tel ensemble de conception particulièrement simple peut être utilisé soit tel que, le point de câblage des fils étant maintenu stable à l'intérieur de la fenêtre ou chambre ouverte du corps cylindrique, et ce sensiblement à mi-hauteur de cette dernière, soit être équipé d'une roulette comportant deux gorges de guidage pour les fils élémentaires, ladite roulette étant alors montée de préférence éclipsable à l'intérieur de la chambre précitée et le point de câblage étant alors situé entre l'orifice d'entrée du canal de sortie et ladite roulette.Such a particularly simple design assembly can be used either such that, the wiring point of the wires being kept stable inside the window or open chamber of the cylindrical body, and this substantially halfway up the latter, or be fitted with a caster having two guide grooves for the elementary wires, said caster then being preferably mounted eclipsable inside the aforementioned chamber and the wiring point then being located between the inlet of the outlet channel and said roulette.

Par ailleurs, grâce à l'invention, il est possible également de réaliser des ensembles compacts, ensembles qui seront désignés par l'expression "ensembles de régulation" qui combinent, d'une part les moyens de régulation de tension du fil provenant de la bobine disposée à l'intérieur du pot de la broche double torsion et, d'autre part, ladite tête de câblage (ou régulateur de longueur) conforme à l'invention et qui permet la réunion des deux fils élémentaires. Dans un tel ensemble intégré, la tête de câblage conforme à l'invention est alors montée libre en rotation directement sur le boitier du tendeur de sortie de la broche, coaxialement à cette dernière, par l'intermédiaire d'un palier fixe, dont la base solidarisée audit boitier du tendeur, se présente sous la forme d'un disque contre la périphérie duquel s'appuie le ballon du fil extérieur, le plateau porte-oeillet du régulateur de longueur comportant éventuellement une embase ou jupe entourant le palier support fixe sur sa hauteur.Furthermore, thanks to the invention, it is also possible to produce compact assemblies, assemblies which will be designated by the expression "regulating assemblies" which combine, on the one hand, the means of regulating the tension of the thread coming from the coil disposed inside the pot of the double twist spindle and, on the other hand, said wiring head (or length regulator) according to the invention and which allows the two elementary wires to be united. In such an integrated assembly, the wiring head according to the invention is then mounted free to rotate directly on the housing of the spindle output tensioner, coaxially with the latter, by means of a fixed bearing, the base secured to said case of the tensioner, is in the form of a disc against the periphery of which the balloon of the outer wire rests, the eyelet holder plate of the length regulator possibly comprising a base or skirt surrounding the fixed support bearing on his height.

Pour réaliser un tel ensemble de régulation comportant à la fois un régulateur de longueur conforme à l'invention et un régulateur de tension, on utilisera par exemple, pour réaliser ce dernier élément (régulateur de tension), un ensemble du type faisant l'objet du brevet européen 409,743, le régulateur de longueur réalisé conformément à l'invention étant alors adapté de manière à pouvoir être monté libre en rotation sur un palier support fixé au boitier dudit régulateur de tension.To produce such a regulation assembly comprising both a length regulator in accordance with the invention and a voltage regulator, use will be made, for example, of producing the latter element (voltage regulator), an assembly of the type which is the subject of European patent 409,743, the length regulator produced in accordance with the invention then being adapted so as to be able to be mounted free in rotation on a support bearing fixed to the housing of said voltage regulator.

  • Figures 2, 2a and 2b are detailed views of an embodiment of a wiring head (or length regulator) produced in accordance with the invention, and in which the connection between the two elementary wires is carried out without presence of guide rollers;
  • Figures 3, 3a, 3b and 4, 4a, 4b, 4c illustrate two embodiments of a wiring head (or length regulator) according to the invention, equipped with a guide wheel for the elementary son;
  • Figures 5 and 6 illustrate an embodiment of an integrated assembly comprising a wiring head according to the invention mounted directly on a length regulator (or tensioner) for the wire from the spool disposed inside the pot of the double twist spindle.

L'invention porte, comme dit précédemment, sur un perfectionnement apporté aux têtes de câblage (ou régulateurs) utilisées sur les machines du type illustré par la figure 1 et dont la structure générale a été détaillée précédemment et ne sera donc pas repris à ce stade de la description, les mêmes références que celles utilisées précédemment étant employées pour désigner les mêmes éléments.The invention relates, as said previously, to an improvement made to the wiring heads (or regulators) used on the machines of the type illustrated in FIG. 1 and the general structure of which has been detailed previously and will therefore not be repeated at this stage. of the description, the same references as those used previously being used to designate the same elements.

Dans les trois exemples de réalisation illustrés aux figures 2, 3 et 4, la tête de câblage proprement dite désignée par la référence générale (7) est montée sur le bâti support (20) de la machine (schématisé uniquement à la figure 3) par l'intermédiaire d'un palier (12) permettant son entraînement en rotation, en marche normale, directement par l'intermédiaire du ballon (1a) du fil (1). Ce montage est réalisé en disposant l'arbre creux (21) de sortie du câblé formé (8) à l'intérieur du palier (12) au moyen de roulements (22).In the three exemplary embodiments illustrated in FIGS. 2, 3 and 4, the wiring head proper designated by the general reference (7) is mounted on the support frame (20) of the machine (shown diagrammatically only in FIG. 3) by by means of a bearing (12) enabling it to rotate, in normal operation, directly through the balloon (1a) of the wire (1). This assembly is carried out by placing the hollow shaft (21) for the outlet of the formed cable (8) inside the bearing (12) by means of bearings (22).

Ainsi que cela ressort des schémas annexés, la tête de câblage (7) est conçue pour pouvoir être montée de manière amovible à l'intérieur du palier (12).As can be seen from the attached diagrams, the wiring head (7) is designed so that it can be removably mounted inside the bearing (12).

Dans les trois formes de réalisation illustrées, l'ensemble amovible constituant la tête de câblage proprement dite (7), comporte essentiellement un corps (25) de forme générale cylindrique et qui présente sur sa hauteur une fenêtre (26) dont les faces (27a,27b) sont parallèles à la génératrice dudit cylindre (25). Ce corps cylindrique (25) est prolongé à son extrémité libre par un plateau circulaire (27) de plus grande dimension, ce plateau pouvant présenter une face biseautée comme illustré aux figures 2 et 4, soit simplement être plat tel que représenté à la figure 3.In the three illustrated embodiments, the removable assembly constituting the actual wiring head (7) essentially comprises a body (25) of generally cylindrical shape and which has at its height a window (26) whose faces (27a , 27b) are parallel to the generator of said cylinder (25). This cylindrical body (25) is extended at its free end by a larger circular plate (27), this plate may have a bevelled face as illustrated in FIGS. 2 and 4, or simply be flat as shown in FIG. 3 .

Un tel ensemble (7) sera de préférence réalisé par moulage d'une matière plastique ou autre matériau, permettant de réaliser l'ensemble léger de manière à réduire au maximum l'inertie.Such an assembly (7) will preferably be produced by molding a plastic or other material, making it possible to produce the light assembly so as to reduce inertia as much as possible.

Ainsi que cela ressort des schémas annexés, le plateau extrême (27) supporte deux oeillets de guidage (28,29). L'oeillet (28) est disposé à proximité du bord périphérique dudit plateau (27) et sert d'élément de guidage pour le fil (1) qui forme le ballon (1a) et permet d'entraîner l'ensemble en rotation lors de la formation du câblé (8). Le second oeillet (29) est, quant à lui, soit confondu avec l'axe de rotation de l'ensemble (exemple illustré par les figures 2, 2a et 2b), soit légèrement décalé par rapport audit axe dans le cas où un tel ensemble est associé à une roulette de guidage pour les deux fils à assembler, tel que cela est illustré dans les deux modes de réalisation (figures 3, 3a, 3b et figures 4, 4a,4b,4c), le second fil (2) provenant de la bobine d'alimentation (21) montée à l'intérieur de la cuvette de la broche étant amené à l'intérieur de cet oeillet de guidage (29).As can be seen from the appended diagrams, the end plate (27) supports two guide eyelets (28,29). The eyelet (28) is disposed near the peripheral edge of said plate (27) and serves as a guide element for the wire (1) which forms the balloon (1a) and makes it possible to drive the assembly in rotation during cable formation (8). The second eyelet (29) is, for its part, either coincident with the axis of rotation of the assembly (example illustrated by Figures 2, 2a and 2b), or slightly offset from said axis in the case where such together is associated with a guide roller for the two wires to be assembled, as illustrated in the two embodiments (FIGS. 3, 3a, 3b and FIGS. 4, 4a, 4b, 4c), the second wire (2) coming from the supply coil (21) mounted inside the bowl of the spindle being brought inside this guide eyelet (29).

Ces deux oeillets (28,29) définissent avec l'orifice d'entrée (30) du canal de sortie (31) du câblé (8), un triangle rectangle ou sensiblement rectangle.These two eyelets (28,29) define with the inlet orifice (30) of the outlet channel (31) of the cable (8), a right triangle or substantially right triangle.

Avec un tel dispositif tel qu'illustré aux figures 2, 2a et 2b, il est possible de réaliser un câblage des deux fils élémentaires (1) et (2) sans utiliser de roulette de guidage, les deux fils étant réunis au point de câblage (33) qui est disposé sensiblement le long de l'axe de rotation de ladite tête, et à mi-hauteur de la fenêtre (26) qu'elle comporte. Un tel mode de réalisation qui implique de délivrer les fils (1) et (2) sous des tensions très précises, est cependant fort avantageux pour réaliser le câblage de fils fragiles, notamment de fils de rayonne, car lesdits fils ne subissent pratiquement aucun embarrage ni frottement lors de leur déplacement.With such a device as illustrated in FIGS. 2, 2a and 2b, it is possible to wire the two elementary wires (1) and (2) without using a guide roller, the two wires being joined at the wiring point. (33) which is arranged substantially along the axis of rotation of said head, and halfway up the window (26) which it comprises. Such an embodiment which involves delivering the wires (1) and (2) under very precise voltages, is however very advantageous for carrying out the wiring of fragile wires, in particular of rayon wires, since said wires undergo practically no interference. nor friction during their displacement.

Par ailleurs, un tel ensemble peut, si cela est souhaitable, être facilement associé à une roulette comportant deux gorges de guidage pour les deux fils élémentaires (1) et (2) comme cela ressort des exemples illustrés par les figures 3 et 4.Furthermore, such an assembly can, if it is desirable, be easily associated with a caster comprising two guide grooves for the two elementary wires (1) and (2) as is apparent from the examples illustrated in FIGS. 3 and 4.

Dans la forme de réalisation illustrée par les figures 3, 3a et 3b, la roulette de guidage (40) est montée à l'intérieur de la fenêtre ouverte (26) par l'intermédiaire d'un axe (41) permettant qu'elle soit entraînée librement en rotation. De préférence, l'axe (41) est constitué d'éléments permettant de monter et démonter facilement ladite roulette (40).In the embodiment illustrated in FIGS. 3, 3a and 3b, the guide roller (40) is mounted inside the open window (26) by means of an axis (41) allowing it is freely rotated. Preferably, the axle (41) is made up of elements making it possible to easily mount and dismount said caster (40).

Par ailleurs, l'oeillet (29) pour le guidage du fil (2) est, par rapport aux positionnement de l'oeillet tel qu'illustré à la figure 2, décalé légèrement par rapport à l'axe de rotation de l'ensemble.Furthermore, the eyelet (29) for guiding the wire (2) is, relative to the positioning of the eyelet as illustrated in FIG. 2, slightly offset relative to the axis of rotation of the assembly .

Une telle conception a comme avantage, d'une part, d'avoir une roulette (40) de guidage emprisonnée à l'intérieur de la fenêtre, ce qui limite tout risque d'échappement du fil lors de l'arrêt d'une position pendant son fonctionnement. Par ailleurs, le léger décalage de l'oeillet de guidage (29) par rapport à l'axe de rotation, permet au fil (2) de former un fuseau (tel que schématisé à la figure 3a), ce qui limite le risque d'enroulement du fil (1) autour du fil (2), notamment lors du démarrage d'une position.On the one hand, such a design has the advantage of having a guide roller (40) trapped inside the window, which limits any risk of the wire escaping when stopping from a position. during its operation. Furthermore, the slight offset of the guide eyelet (29) relative to the axis of rotation, allows the wire (2) to form a spindle (as shown diagrammatically in FIG. 3a), which limits the risk of winding of the wire (1) around the wire (2), in particular when starting a position.

Enfin, les deux gorges de la roulette (40) étant proches l'une de l'autre, le point de câblage (33) des fils se trouve stabilisé dans une zone intermédiaire entre la périphérie de la roulette (40) et l'entrée (30) du canal de sortie du câblé formé.Finally, the two grooves of the caster (40) being close to each other, the wiring point (33) of the wires is stabilized in an intermediate zone between the periphery of the caster (40) and the inlet (30) of the outlet channel of the cable formed.

Les figures 4, 4a, 4b et 4c illustrent une variante d'un tel dispositif qui permet de réaliser une mise en place et un enlèvement aisé de la roulette (40) à l'intérieur de la fenêtre (26) que comporte l'ensemble (7). Dans ce mode de réalisation et ainsi que cela ressort plus particulièrement des figures 4a et 4c, ladite roulette (40) comporte un axe (41) constitué de deux parties élémentaires pouvant être rapprochées l'une de l'autre et qui sont soumises à l'action d'un ressort interne. Par suite, pour remettre en place la roulette, il suffit de repousser les deux bords extrêmes dudit axe (41), les deux extrémités venant s'encastrer automatiquement dans des ouvertures latérales (42a,42b) prévues sur les parois de la fenêtre et, pour enlever ladite roulette, il suffit de réaliser l'opération inverse. Par ailleurs, dans cette forme de réalisation, l'oeillet (29) est monté à la partie inférieure de l'ensemble (7) de manière à pouvoir être rapproché ou éloigné de l'axe de rotation.Figures 4, 4a, 4b and 4c illustrate a variant of such a device which allows for easy installation and removal of the wheel (40) inside the window (26) that includes the assembly (7). In this embodiment and as can be seen more particularly from FIGS. 4a and 4c, said roller (40) comprises an axis (41) consisting of two elementary parts which can be brought together and which are subjected to the action of an internal spring. Consequently, to put the caster back in place, it suffices to push back the two extreme edges of said axis (41), the two ends coming automatically to be embedded in lateral openings (42a, 42b) provided on the walls. of the window and, to remove said roller, it suffices to carry out the reverse operation. Furthermore, in this embodiment, the eyelet (29) is mounted at the lower part of the assembly (7) so as to be able to be moved towards or away from the axis of rotation.

Un tel ensemble présente de nombreux avantages, tels que :

  • mise en place et enlèvement facile de la roulette de guidage du fil ;
  • facilité de nettoyage,
  • positionnement aisé des fils (1) et (2) à câbler par le fait que les roulettes sont "éclipsables", un tel "éclipsage" permettant l'enroulement de un ou plusieurs tours de fils à câbler dans leur gorge respective avec une très grande aisance.
Such a set has many advantages, such as:
  • easy positioning and removal of the wire guide roller;
  • ease of cleaning,
  • easy positioning of the wires (1) and (2) to be wired by the fact that the rollers are "eclipsable", such "eclipsing" allowing the winding of one or more turns of wires to be wired in their respective grooves with a very large ease.

Par ailleurs, un tel ensemble régulateur (7) conforme à l'invention peut être facilement adapté pour être combiné avec l'élément tendeur (6) pour le fil (2) provenant de la broche contenue à l'intérieur du pot (3) de la broche double torsion comme cela ressort de l'exemple de réalisation illustré par les figures 5 et 6.Furthermore, such a regulator assembly (7) according to the invention can be easily adapted to be combined with the tensioning element (6) for the wire (2) coming from the spindle contained inside the pot (3). of the double twist spindle as shown in the embodiment illustrated in FIGS. 5 and 6.

Ainsi que cela ressort de ces figures, un tel ensemble intégré comporte les deux ensembles (6,7) (régulateur de tension et régulateur de longueur), le régulateur (7) étant monté, par l'intermédiaire du boitier (120) de l'élément tendeur (6) directement sur le couvercle (3c) de la broche double torsion (3), ce couvercle et cette broche n'étant pas représentés aux figures 5 et 6.As can be seen from these figures, such an integrated assembly comprises the two assemblies (6,7) (voltage regulator and length regulator), the regulator (7) being mounted, by means of the housing (120) of the 'tensioning element (6) directly on the cover (3c) of the double twist spindle (3), this cover and this spindle not being shown in Figures 5 and 6.

Dans un tel ensemble intégré, le régulateur de tension (6) est réalisé conformément aux enseignements du brevet européen 409 743 et ne sera donc pas décrit en détail.In such an integrated assembly, the voltage regulator (6) is produced in accordance with the teachings of European patent 409 743 and will therefore not be described in detail.

Le montage du régulateur de longueur (7) conforme à l'invention est réalisé, dans cette forme de réalisation particulière, par l'intermédiaire d'une douille ou palier, désigné également par la référence (12), de forme générale cylindrique et qui comporte une base (122) qui sert d'élément de jonction avec la surface supérieure (120a) du boitier (120). Cette base (122) se présente sous la forme d'un disque contre la périphérie duquel peut s'appuyer le ballon (1a) du fil (1) (voir figure 6).The mounting of the length regulator (7) according to the invention is carried out, in this particular embodiment, by means of a bushing or bearing, also designated by the reference (12), of generally cylindrical shape and which has a base (122) which serves as a junction with the upper surface (120a) of the housing (120). This base (122) is in the form of a disc against the periphery of which can support the balloon (1a) of the wire (1) (see Figure 6).

Comme dit précédemment, la tête de câblage (7) a une structure similaire à celle faisant l'objet des figures 2 à 4c, si ce n'est que sa structure est adaptée pour qu'elle puisse être montée libre en rotation sur le palier (12). Pour ce faire, elle comporte, en dessous du plateau (27) qui supporte les oeillets de guidage (28,29) pour les deux fils élémentaires (1,2), un axe creux (124) monté par l'intermédiaire de roulements (22) à l'intérieur du palier cylindrique (12). Par ailleurs, une surface cylindrique ou jupe (126) est également prévue en dessous de la couronne (27), et entoure le palier cylindrique (12) sur toute sa hauteur.As said previously, the wiring head (7) has a structure similar to that which is the subject of FIGS. 2 to 4c, except that its structure is adapted so that it can be mounted to rotate freely on the bearing. (12). To do this, it comprises, below the plate (27) which supports the guide eyelets (28,29) for the two elementary wires (1,2), a hollow pin (124) mounted by means of bearings ( 22) inside the cylindrical bearing (12). Furthermore, a cylindrical surface or skirt (126) is also provided below the crown (27), and surrounds the cylindrical bearing (12) over its entire height.

Grâce à un tel ensemble de conception particulièrement simple pouvant être monté directement sur la broche, il est possible d'obtenir un alignement parfait de l'axe de l'ensemble de régulation avec l'axe de ladite broche.Thanks to such a particularly simple design assembly which can be mounted directly on the spindle, it is possible to obtain perfect alignment of the axis of the regulation assembly with the axis of said spindle.

Par ailleurs, un tel mode de réalisation permet de supprimer de multiples réglages de hauteur, de parallélisme et d'alignement que nécessite un montage conventionnel. En effet, un tel ensemble intègre la distance optimale (A) (voir figure 6) entre le plateau (122) qui non seulement, sert d'élément de jonction entre les deux éléments, mais également permet d'assurer le guidage du ballon (1a) du fil (1) et le plateau supérieur (27) qui supporte les oeillets de guidage (28,29) pour les deux fils élémentaires (1,2), ce qui permet d'éviter toute erreur humaine de réglage et garantir un démarrage optimal du régulateur de longueur du fil (1) du ballon (1a) et d'optimiser les embarrages imposés au fil.Furthermore, such an embodiment makes it possible to eliminate the multiple height, parallelism and alignment adjustments that conventional mounting requires. Indeed, such an assembly integrates the optimal distance (A) (see FIG. 6) between the plate (122) which not only serves as a junction element between the two elements, but also makes it possible to guide the balloon ( 1a) of the wire (1) and the upper plate (27) which supports the guide eyelets (28,29) for both elementary wires (1,2), which makes it possible to avoid any human adjustment error and guarantee an optimal starting of the length regulator of the wire (1) of the balloon (1a) and to optimize the interferences imposed on the wire.

Par ailleurs, un tel ensemble de régulation particulièrement compact permet de protéger le fil (2) du pot, et évite les casses intempestives des fils élémentaires (1) et (2) au démarrage. En effet, la conception du régulateur de longueur (7) et plus particulièrement la présence de la "jupe" tournante (126) qui entoure le palier (12) sur sa hauteur, permet de réaliser une réserve de fil sur cette partie tournante (126), ce qui facilite le démarrage de la production du câblé, et absorbe les chocs éventuels de tension lors de la production.Furthermore, such a particularly compact regulating assembly makes it possible to protect the wire (2) of the pot, and prevents untimely breakage of the elementary wires (1) and (2) at start-up. Indeed, the design of the length regulator (7) and more particularly the presence of the rotating "skirt" (126) which surrounds the bearing (12) over its height, makes it possible to produce a reserve of wire on this rotating part (126 ), which facilitates the start of cable production, and absorbs any voltage shocks during production.

Un tel ensemble permet également de diminuer les balourds provoqués par les masses en rotation, et contribue également à un abaissement des vibrations et nuisances sonores de l'ensemble de la machine.Such an assembly also makes it possible to reduce the imbalances caused by the rotating masses, and also contributes to a lowering of vibrations and noise pollution of the whole machine.

Bien entendu, l'invention n'est pas limitée à un tel exemple de réalisation, mais elle en couvre toutes les variantes réalisées dans le même esprit. Ainsi, si la jupe (126) est de préférence cylindrique, il pourrait être envisagé d'avoir une jupe (126) de forme conique.Of course, the invention is not limited to such an exemplary embodiment, but it covers all the variants produced in the same spirit. Thus, if the skirt (126) is preferably cylindrical, it could be envisaged to have a skirt (126) of conical shape.
