Description

La présente invention se rapporte au domaine des mécanismes de gestion de fils dans un système de traitement et plus particulièrement au domaine des mécanismes de gestion de fils en amont d'une interface de traitement thermique.The present invention relates to the field of son management mechanisms in a processing system and more particularly to the field of son management mechanisms upstream of a heat treatment interface.

Actuellement, lors d'un traitement conjoint de plusieurs fils, l'ensemble des fils traités, provenant de plusieurs bobines, sont réunis pour réaliser un toron.Currently, during a joint processing of several threads, all of the treated threads, coming from several coils, are joined to form a strand.

Cependant, suite aux différentes opérations de traitement effectuées sur ce toron de fils traités simultanément, il a été observé que pour un même toron traité, certains fils présentent des divergences de qualités soulevant un problème dans l'homogénéité du traitement des fils par le dispositif.However, following the various processing operations carried out on this strand of son treated simultaneously, it was observed that for the same strand treated, some son have divergence of qualities raising a problem in the homogeneity of son treatment by the device.

La présente invention a pour but de pallier ces inconvénients en proposant une solution qui permet de supprimer ce problème d'homogénéité entre les différents fils traités.The present invention aims to overcome these disadvantages by proposing a solution that eliminates this problem of homogeneity between the different son treated.

L'invention a ainsi pour objet un dispositif de gestion de fils dans une ligne de traitement de fils en aval d'une boîte à friser et en amont d'un moyen de fixation thermique de la frisure, ledit dispositif comprenant un support fixe, l'entrée de la boîte à friser étant formée par un ou plusieurs rouleaux de frisure d'amenée d'au moins un fil dans la boîte à friser, caractérisé en ce que le dispositif comprend au moins un tambour axial positionné en amont du moyen de fixation thermique, le tambour étant traversé par un fil dans la boite à friser et monté sur le support fixe du dispositif de façon à opérer une rotation sensiblement axiale permettant de générer au moins une fausse torsion aux fils traités.The subject of the invention is thus a device for managing yarns in a yarn processing line downstream of a curling box and upstream of a means for thermal fixation of the crimp, said device comprising a fixed support, inlet of the curling box being formed by one or more crimping rolls for feeding at least one wire into the curling box, characterized in that the device comprises at least one axial drum positioned upstream of the fastening means thermal, the drum being traversed by a wire in the curling box and mounted on the fixed support of the device so as to operate a substantially axial rotation for generating at least one false twist to the treated son.

L'invention porte aussi sur un tambour caractérisé en ce qu'il comprend :

  • un corps sensiblement axial et tubulaire comprenant, d'une part, une surface extérieure et, d'autre part, une surface intérieure, ainsi qu'au moins une ouverture au niveau de chacune de ses extrémités, ces ouvertures étant aptes à permettre le passage d'au moins fil,
  • au moins une interface de montage du corps du tambour sur un bâti autorisant la rotation du corps du tambour autour d'un axe,
  • au moins une surface d'accroche d'au moins un fil, disposée sur la surface intérieure du corps du tambour et apte à permettre l'entrainement en rotation d'au moins un fil avec le corps du tambour.
The invention also relates to a drum characterized in that it comprises:
  • a substantially axial and tubular body comprising, on the one hand, an outer surface and, on the other hand, an inner surface, and at least one opening at each of its ends, these openings being able to allow the passage at least thread,
  • at least one mounting interface of the drum body on a frame allowing rotation of the drum body about an axis,
  • at least one gripping surface of at least one wire, disposed on the inner surface of the drum body and adapted to allow rotation of at least one wire with the drum body.

L'invention concerne également un procédé de gestion de fils dans une ligne de traitement de fils, caractérisé en ce qu'il comprend une étape de génération d'au moins une fausse torsion des fils lors du passage des fils dans un tambour, préalablement à une étape de fixation thermique des fils.The invention also relates to a method for managing yarns in a yarn processing line, characterized in that it comprises a step of generating at least one false twist of the yarns during the passage of the yarns in a drum, prior to a step of thermal fixing of the son.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une représentation schématique d'un exemple de dispositif de gestion de fils selon l'invention dans laquelle les flèches indiquent le sens de déplacement des fils,
  • la figure 2 est une représentation schématique d'un premier exemple de tambour selon l'invention,
  • la figure 3 est une représentation schématique d'un second exemple de tambour selon l'invention.
The invention will be better understood, thanks to the following description, which refers to a preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • the figure 1 is a schematic representation of an example of a wire management device according to the invention in which the arrows indicate the direction of movement of the wires,
  • the figure 2 is a schematic representation of a first example of a drum according to the invention,
  • the figure 3 is a schematic representation of a second example of a drum according to the invention.

La présente invention porte sur un dispositif de gestion 1 de fils dans une ligne de traitement de fils en aval d'une boîte à friser 2 et en amont d'un moyen de fixation thermique de la frisure, ledit dispositif 1 comprenant un support 3 fixe, l'entrée de la boîte à friser 2 étant formée par un ou plusieurs rouleaux de frisure 7 d'amenée d'au moins un fil dans la boîte à friser 2, caractérisé en ce que le dispositif 1 comprend au moins un tambour 4 axial positionné en amont du moyen de fixation thermique, le tambour 4 étant traversé par un fil dans la boite à friser 2 et monté sur le support 3 fixe du dispositif 1 de façon à opérer une rotation sensiblement axiale permettant de générer au moins une fausse torsion aux fils traités.The present invention relates to a device 1 for managing yarns in a line for processing yarns downstream of a curling box 2 and upstream of a means for thermal fixation of the curl, said device 1 comprising a fixed support 3 , the inlet of the curling box 2 being formed by one or more crimping rolls 7 for feeding at least one thread into the curling box 2, characterized in that the device 1 comprises at least one axial drum 4 positioned upstream of the thermal fixing means, the drum 4 being traversed by a wire in the curling box 2 and mounted on the fixed support 3 of the device 1 so as to operate a substantially axial rotation to generate at least one false twist to treated son.

La génération d'une fausse torsion à l'ensemble des fils destinés à subir un traitement thermique permet une homogénéisation de la répartition de ces fils lors de leur pose dans le moyen de fixation thermique.The generation of a false twist to all the son intended to undergo a heat treatment allows homogenization of the distribution of these son during their installation in the thermal fixing means.

Dans leur traversée du tambour axial 4, les fils sont sans tension. La bascule par rotation du tambour 4 permet une modification de la répartition de la portion des fils présent dans le tambour au sein du toron de fils qui les réunit. Cette modification de la répartition des fils par le tambour 4 dans la ligne de traitement permet ainsi une réorganisation des fils au sein du toron sur l'ensemble de leur longueur respective. De même, la génération de cette fausse torsion permet à différentes portions d'un même fil d'être disposées différemment le long de la ligne de traitement, par exemple sur le tapis transporteur, et notamment au niveau de chacune des étapes de traitement du fil avec les autres fils du toron.In their crossing of the axial drum 4, the son are without tension. The latch by rotation of the drum 4 allows a change in the distribution of the portion of the son present in the drum within the son strand that joins them. This modification of the distribution of the son by the drum 4 in the treatment line thus allows a reorganization of the son within of the strand over their entire respective length. Similarly, the generation of this false twist allows different portions of the same wire to be arranged differently along the treatment line, for example on the conveyor belt, and in particular at each of the thread processing stages. with the other wires of the strand.

Ainsi l'invention porte également sur un procédé de gestion de fils dans une ligne de traitement de fils, caractérisé en ce qu'il comprend une étape de génération d'au moins une fausse torsion des fils lors du passage des fils dans un tambour, préalablement à une étape de fixation thermique des fils.Thus, the invention also relates to a method for managing yarns in a yarn processing line, characterized in that it comprises a step of generating at least one false twist of the yarns during the passage of the yarns in a drum, prior to a heat fixing step son.

Une rotation anarchique du tambour 4 permettrait d'aboutir à un résultat de similaire dans l'homogénéisation du traitement des fils au sein du toron. Toutefois, la génération d'une fausse torsion par le tambour 4 présente comme avantages supplémentaires, d'une part, d'éviter un emmêlement des différents fils d'un même toron et, d'autre part, de permettre un démêlage facilité lors de l'opération de bobinage en fin de traitement. Aussi, selon une particularité de construction, le dispositif de gestion 1 de fils selon l'invention est caractérisé en ce que le tambour 4 est monté sur le support 3 fixe du dispositif 1 et arrangé pour opérer un mouvement rotatif pendulaire autour de l'axe du tambour 4.An anarchic rotation of the drum 4 would lead to a similar result in the homogenization of son processing within the strand. However, the generation of a false twist by the drum 4 has the additional advantages, on the one hand, to prevent entanglement of the different wires of the same strand and, on the other hand, to allow easy disentangling during the winding operation at the end of treatment. Also, according to a construction feature, the wire management device 1 according to the invention is characterized in that the drum 4 is mounted on the fixed support 3 of the device 1 and arranged to operate a rotary pendular movement around the axis of the drum 4.

Selon un exemple de construction préféré du dispositif de gestion 1 de l'invention, le tambour 4 est associé à un moyen moteur 5 d'entraînement en rotation. Cette association peut être réalisée par tout mécanisme connu par exemple une courroie d'entraînement ou un engrenage.According to an exemplary preferred construction of the management device 1 of the invention, the drum 4 is associated with a drive means 5 for driving in rotation. This association can be achieved by any known mechanism for example a drive belt or a gear.

Selon une particularité de construction du dispositif complémentaire, l'axe de rotation du tambour 4 est orienté selon un axe sensiblement horizontal. Selon cette construction, le déplacement des fils au travers du tambour 4 est généré soit en amont par l'arrivée des fils par le râtelier d'alimentation qui opère un bourrage dans le tambour 4 en bascule pendulaire, soit en aval par une traction des fils déposés sur un moyen d'entraînement, par exemple un tapis roulant, soit encore une combinaison de ces deux phénomènes.According to a construction feature of the complementary device, the axis of rotation of the drum 4 is oriented along a substantially horizontal axis. According to this construction, the displacement of the son through the drum 4 is generated either upstream by the arrival of the son by the feeding rack which operates a stuffing in the drum 4 pendulum swing, or downstream by pulling the son deposited on a drive means, for example a treadmill, or a combination of these two phenomena.

Il convient de noter que la bascule pendulaire du tambour 4 permet de limiter voire supprimer les tensions sur les fils lorsque ceux-ci sont tractés par le moyen d'entraînement en aval du tambour 4.It should be noted that the pendulum swing of the drum 4 makes it possible to limit or eliminate the tensions on the wires when they are pulled by the drive means downstream of the drum 4.

Selon une alternative de construction à cette particularité, l'axe de rotation du tambour 4 est orienté selon un axe réalisant une inclinaison par rapport à un axe horizontal. Préférentiellement, cette inclinaison est réalisée depuis un point haut en amont du tambour 4 vers un point bas en aval du tambour 4. Une telle inclinaison permet de faciliter le déplacement des fils au travers du tambour 4 depuis un point haut vers un point bas en profitant de la gravité des fils qui constituent le toron qui traverse le tambour 4.According to a construction alternative to this feature, the axis of rotation of the drum 4 is oriented along an axis providing an inclination with respect to a horizontal axis. Preferably, this inclination is made from a high point upstream of the drum 4 to a low point downstream of the drum 4. Such inclination makes it easier to move the threads through the drum 4 from a high point to a low point by taking advantage of of the gravity of the wires which constitute the strand which crosses the drum 4.

L'invention porte aussi plus spécifiquement sur le tambour 4 adapté pour permettre la génération d'une fausse torsion sur les différents fils qui le traversent.The invention also relates more specifically to the drum 4 adapted to allow the generation of a false twist on the various son passing through it.

Le tambour 4 selon l'invention est ainsi caractérisé en ce qu'il comprend :

  • un corps 4a sensiblement axial et tubulaire comprenant, d'une part, une surface extérieure 4b et, d'autre part, une surface intérieure 4c, ainsi qu'au moins une ouverture 4d, 4e au niveau de chacune de ses extrémités, ces ouvertures 4d, 4e étant aptes à permettre le passage d'au moins fil,
  • au moins une interface de montage du corps du tambour 4 sur un bâti 3 autorisant la rotation du corps 4a du tambour 4 autour d'un axe,
  • au moins une surface d'accroche 6 d'au moins un fil, disposée sur la surface intérieure 4c du corps 4a du tambour 4 et apte à permettre l'entrainement en rotation d'au moins un fil avec le corps 4a du tambour 4.
The drum 4 according to the invention is thus characterized in that it comprises:
  • a substantially axial and tubular body 4a comprising, on the one hand, an outer surface 4b and, on the other hand, an inner surface 4c, and at least one opening 4d, 4e at each of its ends, these openings 4d, 4e being able to allow the passage of at least wire,
  • at least one mounting interface of the body of the drum 4 on a frame 3 allowing the body 4a of the drum 4 to rotate about an axis,
  • at least one gripping surface 6 of at least one wire, disposed on the inner surface 4c of the body 4a of the drum 4 and adapted to allow rotation of at least one wire with the body 4a of the drum 4.

Selon un mode de construction préféré, le tambour 4 de l'invention présente un corps 4a de forme sensiblement cylindrique avec une section circulaire ou ovale. Toutefois, cette forme pourrait être de section polygonale, par exemple pentagonale, hexagonale ou octogonale.According to a preferred embodiment, the drum 4 of the invention has a substantially cylindrical body 4a with a circular or oval section. However, this shape could be of polygonal section, for example pentagonal, hexagonal or octagonal.

De façon alternative ou complémentaire, le tambour 4 de l'invention est caractérisé en ce que la surface intérieure 4c du corps 4a du tambour 4 présente une forme sensiblement conique. L'arrangement conique est préférentiellement disposé depuis une ouverture amont restreinte vers une ouverture avale large. Un tel arrangement permet d'opérer une pose facilitée en sortie du tambour 4, par exemple au niveau d'un point précis d'un moyen d'entraînement tel qu'un tapis roulant.Alternatively or additionally, the drum 4 of the invention is characterized in that the inner surface 4c of the body 4a of the drum 4 has a substantially conical shape. The conical arrangement is preferably arranged from a restricted upstream opening to a wide downstream opening. Such an arrangement makes it possible to perform a facilitated installation at the outlet of the drum 4, for example at a precise point of a drive means such as a conveyor belt.

Selon une particularité de construction, le corps 4a du tambour 4 présente une forme tubulaire sensiblement axiale. Toutefois, cet axe du corps 4a du tambour 4 peut être différent de l'axe de rotation du tambour 4 lors de son fonctionnement pour la génération de fausses torsions. Cependant, selon un mode de construction préférentielle, l'axe de rotation du tambour 4 est confondu avec l'axe du corps 4a du tambour 4.According to a construction feature, the body 4a of the drum 4 has a substantially axial tubular shape. However, this axis of the body 4a of the drum 4 may be different from the axis of rotation of the drum 4 during its operation for the generation of false twists. However, according to a preferred embodiment, the axis of rotation of the drum 4 coincides with the axis of the body 4a of the drum 4.

Selon une particularité de construction, le tambour 4 est caractérisé en ce qu'il comprend au moins une surface d'accroche 6 réalisée par au moins un relief de la surface intérieure dans une section perpendiculaire à l'axe du tambour 4. Cette surface d'accroche 6 participe à l'entrainement en rotation des fils pour permettre d'y générer des fausses torsions, conjointement avec la rotation du tambour 4. Outre l'entrainement en rotation, cette surface d'accroche 6 doit cependant autoriser le glissement des fils au travers du corps 4a du tambour 4.According to a particular feature of construction, the drum 4 is characterized in that it comprises at least one gripping surface 6 made by at least one relief of the inner surface in a section perpendicular to the axis of the drum 4. This surface d 6 grip participates in the rotational training of the son to allow to generate false twists, together with the rotation of the drum 4. In addition to the rotational drive, the grip surface 6 must however allow the sliding of the son through the body 4a of the drum 4.

Préférentiellement, cette surface d'accroche 6 est réalisée de façon continue sur la longueur de la surface intérieure 4c du tambour 4 entre l'ouverture amont 4d et l'ouverture avale 4e. Cette surface d'accroche 6 peut également être continue ou discontinue le long du pourtour de la surface intérieure 4c du tambour 4.Preferably, this gripping surface 6 is made continuously along the length of the inner surface 4c of the drum 4 between the upstream opening 4d and the downstream opening 4e. This gripping surface 6 can also be continuous or discontinuous along the periphery of the inner surface 4c of the drum 4.

Selon une première particularité de construction non-limitative de l'invention, cette surface d'accroche 6 est réalisée par une surface rugueuse, par exemple de type toile émeri déposée sur tout ou partie de la surface intérieure 4c du corps 4a du tambour 4.According to a first feature of non-limiting construction of the invention, this gripping surface 6 is made by a rough surface, for example of emery-type deposited on all or part of the inner surface 4c of the body 4a of the drum 4.

Selon une autre particularité de construction, éventuellement complémentaire de la particularité précédente, le tambour 4 est caractérisé en ce qu'il comprend au moins une surface d'accroche 6 réalisée par au moins un relief 6a de la surface intérieure 4c. Ce relief 6a qui réalise un dépassement par rapport à la surface intérieure 4c permet un entraînement en rotation des différents fils avec le tambour 4 au niveau de la portion de fils qui traverse ce tambour 4. Ce relief 6a peut être spécifique d'un entraînement en rotation des fils selon un sens particulier de rotation du tambour 4.According to another construction feature, possibly complementary to the preceding feature, the drum 4 is characterized in that it comprises at least one gripping surface 6 made by at least one relief 6a of the inner surface 4c. This relief 6a which exceeds the inner surface 4c allows a rotation drive of the various son with the drum 4 at the portion of son that passes through the drum 4. This relief 6a may be specific to a training in rotation of the threads according to a particular direction of rotation of the drum 4.

Selon une construction préférentielle de cette particularité, le relief 6a qui forme cette surface d'accroche 6 dans le tambour 4 est disposé de façon à réaliser un relief 6a continu sur la longueur de la surface intérieure 4c du tambour 4 entre l'ouverture amont 4d et l'ouverture avale 4e. De façon alternative, le relief 6a est construit de façon à présenter une variation de sa hauteur entre une hauteur plus importante au niveau d'un point à proximité de l'ouverture amont 4d et une hauteur moins importante au niveau d'un point à proximité de l'ouverture avale 4e.According to a preferred construction of this feature, the relief 6a which forms this gripping surface 6 in the drum 4 is arranged so as to achieve a continuous relief 6a along the length of the inner surface 4c of the drum 4 between the upstream opening 4d and the opening swallows 4th. Alternatively, the relief 6a is constructed to have a variation of its height between a greater height at a point near the upstream opening 4d and a smaller height at a nearby point. from the opening swallows 4th.

Toutefois, selon une spécificité de cette particularité de construction, le relief 6a comprenant un axe de symétrie S qui réalise une intersection avec l'axe de rotation du tambour 4 dans une section perpendiculaire à l'axe de la structure du tambour 4. La réalisation d'un relief 6a comprenant une telle symétrie permet d'opérer un entraînement en rotation des différents fils par le tambour 4 qui soit identique dans les deux sens de rotation du tambour 4. Une telle construction facilite ainsi la génération de fausses torsions homogènes au niveau des différents fils en déplacement dans le tambour 4.However, according to a specificity of this construction feature, the relief 6a comprises an axis of symmetry S which intersects the axis of rotation of the drum 4 in a section perpendicular to the axis of the drum structure 4. The embodiment a relief 6a comprising such a symmetry makes it possible to operate a rotation of the various son by the drum 4 which is identical in both directions of rotation of the drum 4. Such a construction thus facilitates the generation of homogeneous false twists at the level different wires moving in the drum 4.

Selon une particularité de construction du tambour 4, la surface intérieure 4c du corps 4a du tambour 4 comprend au moins deux surfaces d'accroche 6 d'au moins un fil. La multiplication du nombre de surfaces d'accroche 6 du fil à l'intérieur du tambour 4 permet une optimisation de l'entraînement en rotation des fils avec la bascule du tambour 4.According to a construction feature of the drum 4, the inner surface 4c of the body 4a of the drum 4 comprises at least two gripping surfaces 6 of at least one wire. The multiplication of the number of gripping surfaces 6 of the thread inside the drum 4 makes it possible to optimize the rotation of the threads with the rocker of the drum 4.

Selon un mode de construction préférée, le tambour 4 de l'invention est adapté pour être intégré dans un dispositif de gestion 1 de fils selon l'invention.According to a preferred embodiment, the drum 4 of the invention is adapted to be integrated in a son of management device 1 according to the invention.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté 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 embodiment described and shown in the accompanying drawings.
