Description

La présente invention concerne le domaine de la filature et a, plus particulièrement, pour objet des éléments de détour de fils, chacun respectivement par rapport à un organe de roulement du fil sur lui-même, notamment pour une machine à broches creuses telle qu'une machine à guiper.The present invention relates to the field of spinning and, more particularly, relates to wire turning elements, each respectively with respect to a rolling member of the wire on itself, in particular for a machine with hollow spindles such as a guiper machine.

De telles machines sont notamment constituées, par différents modules de guipage, disposés en parallèle, et constitués chacun, par des cylindres délivrant le fil qui passe tout d'abord dans un conduit, puis à l'intérieur d'une broche creuse où il reçoit le filament qui est enroulé autour de lui, ce qui constitue le fil guipé, c'est-à-dire le produit sortant de la machine à guiper.Such machines are in particular constituted by different covering modules, arranged in parallel, and each constituted by cylinders delivering the wire which passes first through a conduit, then inside a hollow spindle where it receives the filament which is wound around it, which constitutes the gimped yarn, that is to say the product leaving the gimping machine.

Actuellement, ces machines sont équipées, en outre, d'organes de fausse torsion, encore appelés "rotafils", assurant une régularité de tension et de guipage quelle que soit la vitesse de filage. Ces "rotafils" sont montés chacun à la sortie de chaque broche creuse, et le fil est maintenu en permanence contre la surface interne de chaque "rotafil" à l'aide d'un élément de détour, par exemple un galet ou autre. (GB-A-1 603 717) Chaque "rotafil" présente donc une surface interne dont la forme et la matière permettent de faire rouler le fil sur lui-même. Ce "rotafil" est, par exemple, en polyuréthane élastomère ou encore en un métal recouvert d'une surface granuleuse du type électro-érosion ou encore recouvert de stries identiques à celles figurant sur les organes de sortie de rotor en filature open end.Currently, these machines are also equipped with false twist members, also called "rotafils", ensuring regularity of tension and wrapping whatever the spinning speed. These "rotafils" are each mounted at the outlet of each hollow spindle, and the wire is permanently held against the internal surface of each "rotafil" with the aid of a detour element, for example a roller or the like. (GB-A-1 603 717) Each "rotafil" therefore has an internal surface whose shape and material allow the thread to roll on itself. This "rotafil" is, for example, made of elastomeric polyurethane or else of a metal covered with a granular surface of the electro-erosion type or else covered with streaks identical to those appearing on the rotor output members in open end spinning.

La présence d'un tel "rotafil" est également indispensable pour réaliser la rattache dite à l'américaine, c'est-à-dire en remontant le fil de la bobine renvidée jusque derrière la bosse de pression du cylindre étireur. En effet, ce "rotafil" favorise grandement le mariage des fibres étirées et du fil de rattache. En actionnant provisoirement la tige qui pousse le fil contre le "rotafil" on obtient précisément un effet favorisant la rattache.The presence of such a "rotafil" is also essential to achieve the so-called American piecing, that is to say by winding the thread of the reel wound up behind the pressure bump of the stretching cylinder. Indeed, this "rotafil" greatly promotes the marriage of stretched fibers and connecting thread. By temporarily actuating the rod which pushes the wire against the "rotafil", an effect promoting the piecing is precisely obtained.

Mais, lesdits organes de fausse torsion, encore appelés "rotafils", présentent l'inconvénient, d'une part, de s'user très rapidement, notamment au niveau de leurs surfaces internes, ce qui entraîne un remplacement très fréquent et, d'autre part, d'ébouriffer le fil et de malmener le filament, ce qui peut même conduire jusqu'à un bouchage complet de la broche, lorsque, comme c'est presque toujours le cas, ils sont placés en aval de celle-ci.However, said false-twist members, also called "rotofils", have the drawback, on the one hand, of wearing out very quickly, in particular at the level of their internal surfaces, which results in very frequent replacement and, on the other hand, to ruffle the wire and to abuse the filament, which can even lead to a complete blockage of the spindle, when, as is almost always the case, they are placed downstream of the latter.

Or, on a constaté que cette fausse torsion n'est nécessaire que lors des trois phases d'accélération, de décélération et d'arrêt de la machine. Par contre, pendant le fonctionnement normal de la machine, une telle fausse torsion appliquée à chaque fil est parfaitement inutile.However, it has been found that this false twist is only necessary during the three phases of acceleration, deceleration and stopping of the machine. By cons, during normal operation of the machine, such a false twist applied to each wire is perfectly unnecessary.

Le problème général à résoudre par l'objet de la présente invention réside, par conséquent, à concevoir un dispositif ne permettant l'utilisation de chaque "rotafil" que lors des trois phases d'accélération, de décélération et d'arrêt de la machine, c'est-à-dire n'appliquant le fil que temporairement contre la surface interne de chaque "rotafil", en général monté en sortie de broche. Ainsi, la durée de vie de chaque "rotafil" en sera considérablement rallongée. Par ailleurs, le fil ne sera plus ébouriffé et le filament ne sera plus malmené, ce qui évitera tous les risques de bouchage de la broche.The general problem to be solved by the object of the present invention therefore lies in designing a device allowing the use of each "rotafil" only during the three phases of acceleration, deceleration and stopping of the machine. , that is to say applying the wire only temporarily against the internal surface of each "rotafil", generally mounted at the spindle outlet. Thus, the lifespan of each "rotafil" will be considerably extended. Furthermore, the thread will no longer be ruffled and the filament will no longer be roughed up, which will avoid all risks of plugging the spindle.

A cet effet, la présente invention a pour objet des éléments de détour de fils, chacun respectivement par rapport à un organe de roulement du fil sur lui-même, notamment pour une machine à broches creuses telle qu'une machine à guiper, éléments caractérisés en ce qu'ils sont mobiles en translation ou en rotation grâce à des moyens de déplacement, chacun sous la forme d'un organe de liaison reliant tous les éléments de détour entre eux, commandé par un moyen d'actionnement et contrôlé par une surveillance électrique, d'une position première, lors du fonctionnement normal de la machine, dans laquelle chaque fil n'est plus en contact avec l'élément de détour correspondant, et ainsi avec l'organe de roulement correspondant, dans une position seconde lors des phases d'accélération, de décélération et d'arrêt de la machine, dans lesquelles chaque fil est alors appliqué par l'élément de détour avec lequel il est en contact, contre l'organe de roulement correspondant, de manière à recevoir durant ces trois phases uniquement, la fausse torsion nécessaire à lui assurer, à ce moment-là, une régularité de tension et de guipage indépendante de la vitesse de filage, et en ce que l'une des deux extrémités de l'organe de liaison est reliée au moyen d'actionnement, et l'autre est reliée à la surveillance électrique, dont un élément de maintien assure un contact électrique lors des trois phases d'accélération, de décélération et d'arrêt de la machine, de manière à ce que cette dernière ne puisse être mise en route que lorsque le contact électrique est assuré, ce dernier étant relâché lorsque la machine tourne normalement.To this end, the present invention relates to wire routing elements, each respectively with respect to a rolling member of the wire on itself, in particular for a hollow pin machine such as a gimp machine, elements characterized in that they are movable in translation or in rotation by means of displacement, each in the form of a connecting member connecting all the detour elements to each other, controlled by an actuating means and controlled by electrical monitoring, from a first position, during normal operation of the machine, in which each wire is no longer in contact with the corresponding detour element, and thus with the corresponding rolling member, in a second position during the acceleration, deceleration and stop phases of the machine, in which each wire is then applied by the detour element with which it is in contact, against the corresponding rolling member, so as to receive during these three phases only, the false twist necessary to assure it, at that time, regularity tension and wrapping independent of the spinning speed, and in that one of the two ends of the connecting member is connected to the actuating means, and the other is connected to the electrical monitoring stick, of which a holding element provides electrical contact during the three phases of acceleration, deceleration and stopping of the machine, so that the latter can only be started when the electrical contact is ensured, the latter being released when the machine is running normally.

The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:

Conformément à l'invention, les éléments de détour 1 de fils 2 sont mobiles en translation ou en rotation grâce à des moyens de déplacement 5, chacun sous la forme d'un organe de liaison 8 reliant tous les éléments de détour 1 entre eux, commandé par un moyen d'actionnement 9 et contrôlé par une surveillance électrique 12, d'une position première 6, lors du fonctionnement normal de la machine, dans laquelle chaque fil 2 n'est plus en contact avec l'élément de détour correspondant, et ainsi avec l'organe de roulement 3 correspondant, dans une position seconde 7 lors des phases d'accélération, de décélération et d'arrêt de la machine, dans lesquelles chaque fil 2 est alors appliqué par l'élément de détour 1 avec lequel il est en contact, contre l'organe de roulement 3 correspondant, de manière à recevoir durant ces trois phases uniquement, la fausse torsion nécessaire à lui assurer, à ce moment-là, une régularité de tension et de guipage indépendante de la vitesse de filage, et l'une 10 des deux extrémités 10, 11 de l'organe de liaison 8 étant reliée au moyen d'actionnement 9, et l'autre 11 étant reliée à la surveillance électrique 12, dont un élément de maintien 13 assure un contact électrique 14 lors des trois phases d'accélération, de décélération et d'arrêt de la machine, de manière à ce que cette dernière ne puisse être mise en route que lorsque le contact électrique 14 est assuré, ce dernier étant relâché lorsque la machine tourne normalement.According to the invention, the detour elements 1 of wires 2 are movable in translation or in rotation thanks to displacement means 5, each in the form of a connecting member 8 connecting all the detour elements 1 to each other, controlled by an actuating means 9 and controlled by an electrical monitoring 12, from a first position 6, during normal operation of the machine, in which each wire 2 is no longer in contact with the corresponding detour element, and thus with the corresponding rolling member 3, in a second position 7 during the acceleration, deceleration and stop phases of the machine, in which each wire 2 is then applied by the detour element 1 with which it is in contact, against the corresponding rolling member 3, so as to receive during these three phases only, the false torsion necessary to ensure it, at that time, regularity of tension and independent covering of the spinning speed, and one 10 of the two ends 10, 11 of the connecting member 8 being connected to the actuating means 9, and the other 11 being connected to the electrical monitoring 12, including one element of holding 13 ensures electrical contact 14 during the three phases of acceleration, deceleration and stopping of the machine, so that the latter can only be started when electrical contact 14 is ensured, the latter being released when the machine is running normally.

Selon un premier mode de réalisation de l'invention, les moyens de déplacement 5 sont sous la forme d'un organe de liaison 8 reliant tous les éléments de détour 1 entre eux, commandé par un moyen d'actionnement 9 et contrôlé par une surveillance électrique 12.According to a first embodiment of the invention, the displacement means 5 are in the form of a connecting member 8 connecting all of the detour elements 1 to one another, controlled by an actuating means 9 and controlled by monitoring electric 12.

Selon une caractéristique de l'invention, et comme le montrent les figures 2 et 3, l'une 10 des deux extrémités 10 et 11 de l'organe de liaison 8 est reliée au moyen d'actionnement 9, et l'autre 11 est reliée à la surveillance électrique 12, dont un élément de maintien 13 assure un contact électrique 14 lors des trois phases d'accélération, de décélération et d'arrêt de la machine, de manière à ce que cette dernière ne puisse être mise en route que lorsque le contact électrique 14 est assuré, ce dernier étant relâché lorsque la machine tourne normalement.According to a characteristic of the invention, and as shown in Figures 2 and 3, one 10 of the two ends 10 and 11 of the connecting member 8 is connected to the actuating means 9, and the other 11 is connected to the electrical monitoring 12, a holding element 13 of which provides electrical contact 14 during the three phases of acceleration, deceleration and stopping of the machine, so that the latter can only be started when the electrical contact 14 is ensured, the latter being released when the machine is running normally.

L'élément de maintien 13 pourra être, par exemple, un taquet.The holding element 13 could be, for example, a cleat.

Comme représenté aux figures 2 et 3, l'organe de liaison 8 pourra être sous la forme d'une tringle reliée à son extrémité 10 à un vérin 9, de manière à pouvoir se déplacer selon un mouvement de translation en va-et-vient.As shown in Figures 2 and 3, the connecting member 8 may be in the form of a rod connected at its end 10 to a cylinder 9, so as to be able to move in a back and forth translation movement .

Les éléments de détour 1 pourront être, par exemple, sous la forme d'un crochet 1 disposé à proximité de l'organe de roulement 3 du fil 2 (figures 2 et 3), ou encore d'au moins un cylindre disposé à proximité dudit organe de roulement 3 du fil 2 (figure 1).The detour elements 1 could be, for example, in the form of a hook 1 placed near the rolling member 3 of the wire 2 (Figures 2 and 3), or even at least one cylinder placed near of said rolling member 3 of wire 2 (Figure 1).

Ainsi, lors du fonctionnement normal de la machine, c'est-à-dire en production de fils 2 guipés, chaque fil passe au milieu du "rotafil" 3 et est appelé et enroulé par les cylindres 15. En effet, pendant le fonctionnement normal de la machine, la tringle 8 est dans la position représentée à la figure 2, c'est-à-dire que les crochets 1 sont écartés de chaque fil 2 guipé qui, en passant au milieu du "rotafil" 3, ne touche ainsi plus la surface interne 16 dudit "rotafil" 3, ce qui fait qu'il n'a plus aucun effet sur le fil 2 guipé.Thus, during normal operation of the machine, that is to say in the production of gimped wires 2, each wire passes through the middle of the "rotafil" 3 and is called up and wound up by the cylinders 15. In fact, during operation normal of the machine, the rod 8 is in the position shown in Figure 2, that is to say that the hooks 1 are separated from each covered wire 2 which, passing in the middle of the "rotafil" 3, does not touch plus the inner surface 16 of said "rotafil" 3, which means that it no longer has any effect on the wrapped wire 2.

Par contre, lors des trois phases d'accélération, de décélération et d'arrêt de la machine, le fil 2 guipé est appliqué contre la surface interne 16 du "rotafil" 3, précisément à l'aide des crochets 1. En effet, durant ces trois phases, la tringle 8 est actionnée par le vérin 9 dans le sens de la flèche 17 et se retrouve dans la position représentée à la figure 3.On the other hand, during the three phases of acceleration, deceleration and stopping of the machine, the wrapped wire 2 is applied against the internal surface 16 of the "rotafil" 3, precisely using the hooks 1. In fact, during these three phases, the rod 8 is actuated by the jack 9 in the direction of the arrow 17 and is found in the position shown in FIG. 3.

Ainsi, les crochets 1 sont dans une position tels qu'ils font faire un détour aux fils 2 guipés qui, de ce fait, se retrouvent appliqués contre la surface interne 16 du "rotafil" 3 de manière à recevoir la fausse torsion qui leur assure, à ce moment là, la régularité de tension et de guipage souhaitée. Puis, lorsque la machine est remise en fonctionnement normal, le vérin 9 repousse la tringle 8, suivant la flèche 18 dans la position représentée à la figure 2, c'est-à-dire celle où le fil 2 guipé n'est plus en contact avec le "rotafil" 3.Thus, the hooks 1 are in a position such that they make a detour to the wrapped wires 2 which, as a result, find themselves applied against the internal surface 16 of the "rotafil" 3 so as to receive the false twist which ensures them , at this time, the regularity of tension and wrapping desired. Then, when the machine is returned to normal operation, the jack 9 pushes the rod 8, along arrow 18 in the position shown in Figure 2, that is to say that where the wrapped wire 2 is no longer in contact with "rotafil" 3.

La longueur de translation des éléments de détour 1 pourra être, par exemple, comprise entre 10 et 40 mm, de préférence 20 mm.The translation length of the detour elements 1 could be, for example, between 10 and 40 mm, preferably 20 mm.

Pour contrôler l'ensemble du fonctionnement, la surveillance électrique 12 montée en bout de tringle 8, par l'intermédiaire du taquet 13,maintient le contact électrique 14 durant les trois phases d'accélération, de décélération et d'arrêt de la machine, de telle manière que cette dernière ne puisse être mise en route que lorsque le contact électrique 14 est assuré. Bien entendu, lorsque la machine tourne normalement, le contact électrique 14 est relâché.To control the entire operation, the electrical monitoring 12 mounted at the end of the rod 8, by means of the cleat 13, maintains the electrical contact 14 during the three phases of acceleration, deceleration and stopping of the machine, so that the latter can only be started when the electrical contact 14 is insured. Of course, when the machine is running normally, the electrical contact 14 is released.

Selon un second mode de réalisation de l'invention, chaque moyen de déplacement 5 est relié directement à chaque élément de détour 1.According to a second embodiment of the invention, each displacement means 5 is connected directly to each detour element 1.

Selon une caractéristique supplémentaire de l'invention, ces moyens de déplacement 5 sont sous la forme chacun d'un moyen d'actionnement 9, ce dernier, étant, par exemple, sous la forme d'un vérin relié à la surveillance électrique 12.According to an additional characteristic of the invention, these displacement means 5 are each in the form of an actuating means 9, the latter being, for example, in the form of a jack connected to the electrical monitoring 12.

Ainsi, dans ce mode de réalisation, il n'y a pas d'éléments de liaison 8 entre lesdits éléments de détour 1. Ceux-ci sont actionnés individuellement, chacun, par exemple, par un vérin 9.Thus, in this embodiment, there are no connecting elements 8 between said detour elements 1. These are actuated individually, each, for example, by a jack 9.

Les moyens de déplacement 5 peuvent également être directement sous la forme, par exemple, chacun d'un levier pouvant être manoeuvré individuellement et manuellement grâce à une poignée 19 (figures 4 et 5).The displacement means 5 can also be directly in the form, for example, each of a lever which can be maneuvered individually and manually by means of a handle 19 (FIGS. 4 and 5).

Une telle variante est utilisée lorsqu'il est nécessaire de réaliser une rattache dite à l'américaine. Ainsi, lorsque la machine fonctionne normalement, le fil 2 n'est pas en contact avec l'élément de détour 1, ni avec l'organe de roulement 3. Lors des phases d'accélération, de décélération et d'arrêt de la machine, chaque levier 5 est abaissé et l'élément de détour 1 qui y est fixé fait faire un détour au fil 2 qui se met ainsi en contact avec le rotafil 16.Such a variant is used when it is necessary to carry out a so-called American connection. Thus, when the machine is operating normally, the wire 2 is not in contact with the detour element 1, nor with the rolling member 3. During the acceleration, deceleration and stopping phases of the machine , each lever 5 is lowered and the detour element 1 which is attached to it makes a detour to the wire 2 which thus comes into contact with the rotafil 16.

Les leviers 5 peuvent être levés ou baissés tous en même temps ou alors, et c'est là l'objet de la présente variante, être manoeuvrés individuellement par la poignée 19.The levers 5 can be raised or lowered all at the same time or else, and this is the object of the present variant, to be maneuvered individually by the handle 19.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiments described and shown in the drawings attached. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
