Description

L'invention concerne le domaine de la fabrication des fils métalliques destinés à la réalisation de renforts de pneumatiques. De manière générale, ces fils servent à constituer des nappes de renfort constituées de tronçons de fils enrobés dans un mélange de caoutchouc, parallèles entre eux, et faisant un angle donné avec la direction longitudinale de la nappe.The invention relates to the field of the manufacture of metal son for the realization of tire reinforcements. In general, these threads serve to form reinforcing plies consisting of sections of son embedded in a rubber mixture, parallel to one another, and forming a given angle with the longitudinal direction of the ply.

Ces fils peuvent être des fils unitaires ou des assemblages de fils obtenus par retordage de fils unitaires métalliques.These son may be single son or wire assemblies obtained by twisting single son metal.

De manière à améliorer leur résistance, certains de ces fils, du type des fils formés par assemblage, ont la particularité de présenter une âme enrobée dans du caoutchouc. Toutefois, la fabrication de ces fils particuliers peut causer des irrégularités à la surface du fil, liées à des débordements de la gomme servant à gainer l'âme du fil sur les couches extérieures dudit fil.In order to improve their resistance, some of these son, of the type of son formed by assembly, have the particularity of having a core embedded in rubber. However, the manufacture of these particular son can cause irregularities on the surface of the wire, related to overflows of the rubber used to sheath the core of the wire on the outer layers of said wire.

Ces irrégularités peuvent entraîner des anomalies lors de la réalisation des nappes de renfort en modifiant localement le pas entre deux fils et en altérant la qualité des ponts de gomme que l'on cherche à réaliser entre les fils pour les lier entre eux.These irregularities may cause anomalies during the production of reinforcement plies by locally changing the pitch between two son and altering the quality of rubber bridges that are sought to achieve between the son to bind them.

Aussi, il s'avère nécessaire dans certains cas de compléter le processus de fabrication des fils présentant une âme gainée dans du caoutchouc par une étape de nettoyage destinée à enlever toutes les traces de gomme indésirables.Also, it is necessary in some cases to complete the manufacturing process of the son having a core sheathed in rubber by a cleaning step for removing all traces of unwanted gum.

L'invention a pour objet de proposer un dispositif et un procédé destiné à mener à bien cette étape supplémentaire.The object of the invention is to propose a device and a method for carrying out this additional step.

Le document FR 2364 705 divulgue un dispositif de brossage d'un fil métallique selon le préambule de la revendication 1.The document FR 2364705 discloses a device for brushing a wire according to the preamble of claim 1.

Le dispositif de brossage d'un fil métallique selon l'invention est tel que divulgué par la revendication 1.The brushing device of a wire according to the invention is as disclosed by claim 1.

L'invention concerne aussi différentes méthodes d'utilisation du dispositif selon les revendications 6 à 8.The invention also relates to different methods of using the device according to claims 6 to 8.

Les différents modes de réalisation particuliers du dispositif sont divulgués par les revendications dépendantes 2 à 5.The various particular embodiments of the device are disclosed by the dependent claims 2 to 5.

Les différents modes de réalisation particuliers de la méthode sont divulgués par les revendications dépendantes 9 à 11.The various particular embodiments of the method are disclosed by dependent claims 9 to 11.

De la sorte, il est possible d'exercer une certaine pression sur le fil avec les brosses de manière à augmenter l'efficacité de brossage et permettre une élimination des résidus de caoutchouc présents à la surface du fil, sans que l'effort d'application des brosses sur le fil déforme le fil en raison de la tension exercée sur le fil.In this way, it is possible to exert a certain pressure on the wire with the brushes so as to increase the brushing efficiency and allow elimination of the rubber residues present on the surface of the wire, without the effort of Applying the brushes on the wire deforms the wire due to the tension exerted on the wire.

La description qui suit permet de décrire le dispositif à l'aide d'un exemple de mise en oeuvre et s'appuie sur

  • la figure 1 qui représente une vue en perspective du dispositif selon l'invention.
  • la figure 2 qui représente une vue schématique du fonctionnement du moyen d'applique,
  • Les figures 3 à 5 qui représentent différentes variantes de disposition des brosses.
The description which follows makes it possible to describe the device with the aid of an example of implementation and is based on
  • the figure 1 which represents a perspective view of the device according to the invention.
  • the figure 2 which represents a schematic view of the operation of the applying means,
  • The Figures 3 to 5 which represent different variants of arrangement of the brushes.

Le dispositif illustré à la figure 1 comprend un châssis 1 sur lequel sont implantés les organes destinés à réaliser le brossage des fils.The device illustrated in figure 1 comprises a frame 1 on which are implanted the organs for brushing the son.

Le fil F circule, depuis un moyen de déroulage amont (non représenté) vers un moyen de réception aval (non représenté). Toutefois, il est tout à fait possible d'insérer un dispositif équivalent en fin de ligne d'une unité de gommage et d'assemblage du fil, ou encore en amont d'un processus de calandrage ou de réalisation d'un fil engommé.The wire F flows from an upstream unwinding mechanism (not shown) to a downstream receiving means (not shown). However, it is quite possible to insert an equivalent end-of-line device of a scrubber and wire assembly unit, or upstream of a calendering process or realization of an enameled wire.

Les moyens d'entraînement du fil F dans le dispositif sont formés par les cabestans 310 et 320 et par les moyens de déroulage ou d'alimentation situés en amont, et les moyens de réception situés en aval comportant chacun leur propre motorisation.The means for driving the wire F in the device are formed by the capstans 310 and 320 and the unwinding means or supply located upstream, and the receiving means located downstream each having their own motorization.

Dans le cas spécifique du dispositif faisant l'objet de la présente description, l'ensemble de brosses est constitué de deux paires de brosses rotatives 21 et 22. Ces paires de brosses sont disposées sur le trajet du fil qui circule de manière rectiligne entre deux cabestans 31 et 32. Les brosses (210, 211, 220, 221) ont une forme sensiblement circulaire de rayon r.In the specific case of the device which is the subject of the present description, the set of brushes consists of two pairs of rotating brushes 21 and 22. These pairs of brushes are arranged on the path of the wire which flows rectilinearly between two capstans 31 and 32. The brushes (210, 211, 220, 221) have a substantially circular shape of radius r.

Les axes de rotation d'une paire de brosse sont parallèles entre eux et sensiblement perpendiculaires à la direction C de circulation du fil. Les axes des deux paires de brosses sont également perpendiculaires entre eux.The axes of rotation of a pair of brushes are parallel to one another and substantially perpendicular to the direction C of circulation of the wire. The axes of the two pairs of brushes are also perpendicular to each other.

Lorsqu'il est prévu de disposer plus de deux paires de brosses, les axes sont alors disposés de sorte que les directions des axes fassent entre elles des angles égaux de manière à atteindre toute la circonférence du fil à brosser comme cela est illustré à la figure 5 où les axes des deux paires de brosses sont perpendiculaires entre eux et parallèle à un plan perpendiculaire au sens de circulation C du fil dans le dispositif de brossage.When it is planned to have more than two pairs of brushes, the axes are then arranged so that the directions of the axes make equal angles between them so as to reach the entire circumference of the wire to be brushed as shown in FIG. figure 5 wherein the axes of the two pairs of brushes are perpendicular to each other and parallel to a plane perpendicular to the flow direction C of the wire in the brushing device.

Les axes des brosses peuvent être disposés de manière à être situés dans un plan P perpendiculaire à la direction C de circulation du fil comme cela est représenté à la figure 3 ou, comme cela est illustré dans la figure 4, être décalés d'une longueur d donnée.The axes of the brushes may be arranged so as to be located in a plane P perpendicular to the direction C of movement of the wire as shown in FIG. figure 3 or, as illustrated in the figure 4 , be offset by a given length.

Chaque paire de brosse est montée sur une platine (41, 42) qui supporte l'ensemble de motorisation des brosses (non représenté). Au moins une des brosses de la paire comprend des moyens d'applique, aptes à mettre les brosses en contact avec le fil.Each pair of brushes is mounted on a plate (41, 42) which supports the motorization assembly of the brushes (not shown). At least one of the brushes of the pair comprises applying means adapted to put the brushes in contact with the wire.

Dans le cas d'espèce, chacun des axes des brosses est monté mobile de manière à circuler dans une lumière 229 pratiquée sur la platine 42. Le trajet de la brosse s'effectue selon la direction sensiblement circulaire de la flèche T, telle qu'illustrée à la figure 2. A titre exemplatif, l'axe 222 de la brosse 221 est porté par un bras 223 pivotant autour d'un axe 224 monté sur la platine et relié à un actionneur formé lui-même d'un bras 225 relié par un axe 226 au piston 227 d'un vérin 228. L'axe de la brosse demeure perpendiculaire au plan de la platine 42 pendant ce mouvement. Ce mécanisme est placé sous la platine de manière à être isolé des particules de gomme arrachées de la surface du fil pendant l'opération de brossage. Des mécanismes identiques sont prévus pour animer le mouvement des brosses 220, 210 et 211.In the present case, each of the axes of the brushes is movably mounted so as to circulate in a slot 229 made on the plate 42. The path of the brush is made in the substantially circular direction of the arrow T, such that illustrated at figure 2 . By way of example, the axis 222 of the brush 221 is carried by an arm 223 pivoting about an axis 224 mounted on the plate and connected to an actuator itself formed by an arm 225 connected by an axis 226 to the piston 227 of a cylinder 228. The axis of the brush remains perpendicular to the plane of the plate 42 during this movement. This mechanism is placed under the plate so as to be isolated from the gum particles torn from the surface of the wire during the brushing operation. Identical mechanisms are provided to animate the movement of the brushes 220, 210 and 211.

Lorsque le dispositif est en fonctionnement, les brosses 220 et 221 viennent presser le fil qui est alors mis en contact simultanément avec les circonférences des deux brosses de la paire, qui exercent alors sur lui une pression d'applique donnée. La force d'applique des brosses sur le fil peut utilement être comprise entre 1 N et 8 N.When the device is in operation, the brushes 220 and 221 come to press the wire which is then brought into contact simultaneously with the circumferences of the two brushes of the pair, which then exert on it a given applied pressure. The force of applying brushes on the wire can usefully be between 1 N and 8 N.

Les brosses (210, 211, 220, 221) sont entraînées en rotation par des moteurs (non visibles) disposés sous les platines 41, 42. Les brosses d'une paire donnée ont des vitesses de rotation identiques mais de sens opposées (voir les figures 3, 4 et 5) de manière à permettre si nécessaire aux poils des brosses de s'interpénétrer. On s'arrange également pour que la vitesse tangentielle des brosses au point de contact avec le fil soit de sens opposée au sens de circulation du fil dans le dispositif.The brushes (210, 211, 220, 221) are rotated by motors (not visible) arranged under the plates 41, 42. The brushes of a given pair have identical speeds of rotation in opposite directions (see FIG. Figures 3, 4 and 5 ) so as to allow, if necessary, the bristles of the bristles to interpenetrate. It is also arranged that the tangential speed of the brushes at the point of contact with the wire is opposite to the direction of flow of the wire in the device.

La vitesse de rotation des brosses peut utilement être comprise entre 3000 t/min et 6000 t/min. On observera ici que plus la vitesse de rotation des brosses est élevée, meilleur est le brossage du fil. De plus à ces vitesses on bénéficie des effets de la force centrifuge pour forcer l'évacuation des particules de gomme arrachées de la surface du fil.The speed of rotation of the brushes can usefully be between 3000 rpm and 6000 rpm. It will be observed here that the higher the speed of rotation of the brushes, the better is the brushing of the wire. Moreover, at these speeds, the effects of the centrifugal force are used to force the evacuation of the gum particles torn from the surface of the wire.

A cet effet, pour se protéger des projections de particules, on peut placer le dispositif dans une enceinte fermée 5 dans laquelle on fait circuler de l'air A à l'aide d'un moyen de ventilation forcée de manière à s'assurer de l'évacuation desdites particules de gomme dans un moyen de recueillement des poussières adapté.For this purpose, to protect itself from projections of particles, the device can be placed in a closed chamber 5 in which air A is circulated by means of forced ventilation means so as to ensure that evacuating said gum particles in a suitable dust collecting means.

Il est alors important de faire en sorte que le fil reste le plus rectiligne possible pour que le travail des brosses soit efficace. A cet effet, des moyens de régulation de la tension sont placés en amont 31 et en aval 32 de l'ensemble de brosses, et qui ont pour objet de maintenir une tension donnée et calibrée tout au long du parcours du fil le long des paires de brosse. Ces moyens sont formés par un cabestan amont 31 et un cabestan aval 32 autour de chacun desquels le fil est enroulé plusieurs fois.It is important to ensure that the wire remains as straight as possible so that the brush work is effective. For this purpose, voltage regulation means are placed upstream 31 and downstream 32 of the set of brushes, and whose object is to maintain a given voltage and calibrated throughout the course of the wire along the pairs of brush. These means are formed by an upstream capstan 31 and a downstream capstan 32 around each of which the wire is wound up several times.

Chaque cabestan est animé en rotation par un moteur de type moteur asynchrone 310, 320. Le moteur du cabestan situé en aval de l'ensemble de brosse a une vitesse de rotation imposée en fonction de la vitesse d'avance du fil dans le processus. On asservi alors la vitesse du moteur amont 310 sur la vitesse du moteur aval 320 et on impose au moteur amont 310 un couple freineur, de manière à mettre le fil en tension entre les deux cabestans 31 et 32.Each capstan is rotated by an asynchronous motor type motor 310, 320. The capstan motor located downstream of the brush assembly has a rotational speed imposed depending on the feed speed of the wire in the process. The speed of the upstream engine 310 is then controlled on the speed of the downstream engine 320 and a braking torque is imposed on the upstream engine 310, so as to put the wire in tension between the two capstans 31 and 32.

On obtient de bons résultats de brossage en imposant au fil une tension comprise entre 5 daN et 20 daN déterminée en particulier en fonction du diamètre du fil à brosser.Good brushing results are obtained by imposing on the wire a tension of between 5 daN and 20 daN determined in particular as a function of the diameter of the wire to be brushed.

Ainsi, de manière générale, plus la tension dans le fil est élevée plus il sera possible d'appliquer les brosses avec une pression élevée et meilleur sera la qualité du brossage effectué.Thus, in general, the higher the tension in the yarn, the more it will be possible to apply the brushes with high pressure and the better the quality of the brushing performed.

La vitesse de défilement du fil dans le dispositif peut varier de 50 m/min à 600m/min, voire plus. On observera que la vitesse de défilement du fil dans le dispositif peut facilement être elle-même asservie à la vitesse de défilement du fil dans un processus amont ou aval sans qu'il soit porté préjudice à la qualité du brossage effectué.The speed of travel of the wire in the device can vary from 50 m / min to 600m / min or more. It will be observed that the running speed of the wire in the device can easily itself be controlled by the speed of travel of the wire in an upstream or downstream process without prejudice to the quality of the brushing performed.

Les poils des brosses sont formés par de fils métalliques radiaux disposés sur le moyeu de la brosse. Il peut s'avérer judicieux de choisir des poils de brosse dans un matériau dont la dureté est ajustée de manière à éviter de dégrader les revêtements du fil à brosser.The bristles of the brushes are formed by radial metal wires arranged on the hub of the brush. It may be advisable to choose brush bristles in a material whose hardness is adjusted so as to avoid degrading the coatings of the wire to be brushed.
