Description

La présente invention concerne un dispositif de revêtement d'un fil conducteur.The present invention relates to a device for coating a conductive wire.

Le document EP-0 875 299 représente le préambule de la revendication 1 et divulgue un dispositif de revêtement d'un fil conducteur qui comporte un applicateur de vernis sur le fil et un four d'émaillage dans lequel défile le fil. Le four comprend à cet effet une chambre équipée d'éléments chauffants en regard de la trajectoire du fil pour permettre l'évaporation de solvants du vernis ainsi que la cuisson de ce vernis. Les vapeurs de solvants sont traitées par combustion au contact des éléments chauffants, sans flamme résultante, sous atmosphère contrôlée à faible teneur en oxygène. Pour ce faire, la chambre comporte une sonde de mesure de la teneur en oxygène ainsi qu'un entrée d'alimentation d'air asservie à la mesure de la sonde. Selon ce document, un ventilateur est monté en regard de l'entrée d'alimentation d'air. Ainsi, l'air circule dans la chambre et il se produit un mélange entre le flux d'air introduit et le flux d'air et de vapeurs présent dans le chambre.EP-0 875 299 represents the preamble of claim 1 and discloses a coating device of a conductive wire which comprises a lacquer applicator on the wire and an enameling furnace in which the wire runs. The oven comprises for this purpose a chamber equipped with heating elements facing the path of the wire to allow the evaporation of solvents varnish and the cooking of this varnish. The solvent vapors are treated by combustion in contact with the heating elements, without a resulting flame, under a controlled atmosphere with a low oxygen content. To do this, the chamber comprises a probe for measuring the oxygen content and an air supply inlet controlled by the measurement of the probe. According to this document, a fan is mounted opposite the air supply inlet. Thus, the air circulates in the chamber and there is a mixture between the air flow introduced and the flow of air and vapors present in the chamber.

Ce dispositif, quoique présentant de nombreux avantages, ne donne cependant pas entièrement satisfaction.This device, although having many advantages, does not, however, fully satisfactory.

En effet, le flux d'air introduit est dirigé par le ventilateur en partie vers l'applicateur de vernis, ce qui a pour conséquence de détériorer la qualité du revêtement et d'entraîner une oxydation immédiate des solvants créant des flammes à la surface du fil qui détériorent la qualité du revêtement.Indeed, the air flow introduced is directed by the fan in part towards the varnish applicator, which has the effect of deteriorating the quality of the coating and cause immediate oxidation of solvents creating flames on the surface of the coating. wire that deteriorate the quality of the coating.

La présente invention a pour objet de remédier à ces inconvénients, et notamment de mettre au point un dispositif de revêtement d'un fil conducteur permettant d'obtenir un fil émaillé sans entraîner la création de flammes à la surface du fil à l'intérieur du four d'émaillage.The object of the present invention is to remedy these drawbacks, and in particular to develop a device for coating a conductive wire making it possible to obtain an enamelled wire without causing the creation of flames on the surface of the wire inside the wire. enameling furnace.

Cet objet est atteint par le caractéristiques de la partie caractérisante de la revendication 1.This object is achieved by the features of the characterizing part of claim 1.

Grâce à l'invention, on évite d'entraîner les solvants évaporés vers le fil, de sorte qu'on empêche la formation de flammes à la surface du fil revêtu. On améliore ainsi très nettement la qualité du revêtement.Thanks to the invention, it is avoided to cause the solvents evaporated towards the wire, so that the formation of flames on the surface of the coated wire is prevented. This improves the quality of the coating very clearly.

De manière très avantageuse, le traitement desdits solvants par combustion a lieu dans une zone dite de combustion desdits solvants communiquant avec ladite chambre.Very advantageously, the treatment of said solvents by combustion takes place in a so-called combustion zone of said solvents communicating with said chamber.

Ledit ventilateur est situé avant ladite entrée d'alimentation d'air par rapport à la direction de circulation desdits solvants.Said fan is located before said air supply inlet with respect to the flow direction of said solvents.

Selon un caractéristique avantageuse de l'invention, un conduit d'alimentation d'air communiquant à ses deux extrémités avec ladite chambre, et d'autre part avec ladite entrée d'alimentation d'air est ménagé à l'intérieur dudit four, de manière à former un circuit fermé de circulation de gaz, ledit circuit comprenant ladite zone de cuisson dudit vernis, ladite zone d'évaporation desdits solvants et la zone de combustion desdits solvants, les gaz circulant dans ce circuit en sens inverse de la direction de défilement dudit fil à l'intérieur de ladite chambre.According to an advantageous characteristic of the invention, an air supply duct communicating at its two ends with said chamber, and secondly with said air supply inlet is provided inside said furnace, so as to form a closed gas circulation circuit, said circuit comprising said cooking zone of said varnish, said evaporation zone of said solvents and the combustion zone of said solvents, the gases circulating in this circuit in the opposite direction to the scrolling direction said wire within said chamber.

D'autres caractéristiques et avantages de la présente invention apparaîtront dans la description qui va suivre d'un mode de réalisation de l'invention, donné à titre illustratif et nullement limitatif.Other features and advantages of the present invention will appear in the following description of an embodiment of the invention, given by way of illustration and in no way limiting.

La figure unique est une vue en coupe très schématique d'un dispositif de revêtement d'un fil conducteur selon l'invention.The single figure is a very schematic sectional view of a device for coating a conductive wire according to the invention.

Ce dispositif 100 comprend un applicateur de vernis 1 et un four d'émaillage 2 monté à la suite de l'applicateur et couplé à celui-ci, à travers lesquels un fil conducteur 3 défile horizontalement dans la réalisation illustrée. Bien entendu, en variante, le dispositif 100 peut être disposé verticalement. L'applicateur de vernis 1 contient le vernis dissout dans des solvants pour le dépôt d'une couche de ce vernis sur le fil 3 défilant dans l'applicateur.This device 100 comprises a varnish applicator 1 and an enamelling furnace 2 mounted after the applicator and coupled thereto, through which a conductive wire 3 scrolls horizontally in the illustrated embodiment. Of course, alternatively, the device 100 may be arranged vertically. The varnish applicator 1 contains the varnish dissolved in solvents for depositing a layer of this varnish on the wire 3 running in the applicator.

Le four d'émaillage 2 comporte une chambre unique 4 pour l'évaporation des solvants de la couche de vernis sur le fil, le traitement des vapeurs de solvants et la cuisson à haute température du vernis sur le fil, au fur et à mesure du défilement du fil dans cette chambre.The enameling furnace 2 comprises a single chamber 4 for evaporation of the solvents from the coating layer on the wire, the treatment of the solvent vapors and the high temperature firing of the varnish on the wire, as and when required. scrolling the wire in this room.

Ce four 2 présente une entrée 5 et une sortie 6 du fil 3 dans la chambre 4, prévues à ses extrémités opposées. Il comporte également une paroi longitudinale inférieure 8 et une paroi longitudinale supérieure 9 de préférence formée d'une double paroi 9A, 9B. Le four 2 est en outre équipé d'éléments chauffants rayonnants (non représentés), montés dans la chambre 4 en regard de la trajectoire du fil 3 dans celle-ci, par exemple dans la paroi 9A. Ce sont des résistances électriques choisies pour permettre de porter la chambre 4 à une température de l'ordre de 1000°C.This oven 2 has an inlet 5 and an outlet 6 of the wire 3 in the chamber 4, provided at its opposite ends. It also comprises a lower longitudinal wall 8 and an upper longitudinal wall 9 preferably formed of a double wall 9A, 9B. The oven 2 is also equipped with radiant heating elements (not shown), mounted in the chamber 4 facing the path of the wire 3 therein, for example in the wall 9A. These are electrical resistances chosen to allow to carry the chamber 4 to a temperature of the order of 1000 ° C.

La chambre 4 est de préférence, ainsi qu'il est décrit dans le document EP-0 875 299, à atmosphère intérieure à faible teneur en oxygène, par exemple inférieure à 6% et de préférence inférieure à 3%. Cette teneur est contrôlée. A cet effet, la chambre 4 est équipée d'une sonde 10 de mesure de la teneur en oxygène de l'atmosphère intérieure de la chambre 4. Une entrée contrôlée d'air 11 est asservie à la sonde 10 et assure le maintien de la teneur en oxygène dans la chambre à la valeur souhaitée.The chamber 4 is preferably, as described in EP-0 875 299, with a low oxygen interior atmosphere, for example less than 6% and preferably less than 3%. This content is controlled. For this purpose, the chamber 4 is equipped with a probe 10 for measuring the oxygen content of the interior atmosphere of the chamber 4. A controlled air inlet 11 is slaved to the probe 10 and maintains the oxygen content in the chamber at the desired value.

L'entrée d'alimentation d'air 11 débouche dans un conduit d'alimentation 12, avantageusement mais non nécessairement défini par les parois 9A, 9B du four 2 et débouchant à ses deux extrémités dans les parties terminales d'entrée 5 et de sortie 6 de la chambre 4. Un ventilateur 13 est monté dans le conduit d'alimentation d'air 12.The air supply inlet 11 opens into a supply duct 12, advantageously but not necessarily defined by the walls 9A, 9B of the oven 2 and opening at its two ends in the inlet and outlet end portions 5 6 of the chamber 4. A fan 13 is mounted in the air supply duct 12.

Pusieurs zones sont définies dans le four : une zone A de cuisson du vernis, une zone B d'évaporation des solvants située au voisinage immédiat de l'entrée 5 du fil 3, et une zone C de traitement des solvants évaporés par combustion.Several zones are defined in the furnace: a zone A for cooking the varnish, a zone B for the evaporation of solvents located in the immediate vicinity of the inlet 5 of the wire 3, and a zone C for treating the solvents evaporated by combustion.

Selon l'invention, le ventilateur 13 et l'entrée d'alimentation d'air 11 sont situés à des positions distinctes et espacées l'une de l'autre ; plus précisément, le ventilateur 13 est situé entre la zone B d'évaporation des solvants et l'entrée d'alimentation d'air 11 de manière à entraîner les solvants vers l'entrée d'alimentation d'air 11 afin que les solvants soient traités par combustion au niveau de la zone C de traitement des solvants, en dehors de la zone de cuisson A du vernis. En d'autres termes, lors du défilement du fil 3 revêtu de sa couche de vernis dans la chambre 4, selon la direction de droite à gauche sur la figure, représentée par le flèche F, les solvants s'évaporent de la couche de vernis au niveau de la zone B. Les vapeurs de solvants de la zone B, entraînées par le ventilateur 13 vers l'entrée d'alimentation d'air 11 et la zone C sont ensuite brûlées complètement au niveau de la zone C. La circulation des gaz à l'intérieur du four 2 est illustrée par les flèches G et a lieu en sens inverse de la direction F au sein de la zone A.According to the invention, the fan 13 and the air supply inlet 11 are located at distinct positions and spaced apart from each other; more specifically, the fan 13 is located between the solvent evaporation zone B and the air supply inlet 11 so as to entrain the solvents towards the air supply inlet 11 so that the solvents are treated by combustion at the zone C of solvent treatment, outside the cooking zone A of the varnish. In other words, during the running of the wire 3 coated with its varnish layer in the chamber 4, in the direction from right to left in the figure, represented by the arrow F, the solvents evaporate from the varnish layer at the level of zone B. The vapors of solvents in zone B, driven by the fan 13 to the air supply inlet 11 and zone C, are then burned completely at the level of zone C. The circulation of gas inside the furnace 2 is illustrated by the arrows G and takes place in the opposite direction of the direction F within the zone A.

Ainsi, selon l'invention, le ventilateur 13 est situé avant l'entrée d'alimentation d'air 11 par rapport à la direction G de circulation des gaz.Thus, according to the invention, the fan 13 is located before the air supply inlet 11 relative to the direction G of gas flow.

Bien entendu, la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit.Of course, the present invention is not limited to the embodiment which has just been described.

Notamment, l'alimentation contrôlée en air de la chambre peut être faite de manière différente de celle illustrée, en n'intégrant pas le conduit d'alimentation dans l'une des parois du four.In particular, the controlled air supply of the chamber may be made differently than illustrated, by not integrating the supply duct in one of the walls of the oven.

Par ailleurs, le dispositif de revêtement peut comporter plusieurs ensembles analogues à l'ensemble formé de l'applicateur 1 et du four 2, et sont alors montés à la suite l'un de l'autre ou des autres.Furthermore, the coating device may comprise several sets similar to the assembly formed of the applicator 1 and the oven 2, and are then mounted one after the other or the others.
