Description

La présente invention concerne une enrubanneuse permettant l'enru­bannage à chaud d'un conducteur électrique.The present invention relates to a wrapper allowing the hot wrapping of an electrical conductor.

Dans les grandes machines électriques, la technique de l'isolation des conducteurs consiste à enrouler un ou plusieurs rubans isolants en plusieurs couches successives selon un pas hélicoïdal, puis à calibrer les dimensions du conducteur au moyen de rouleaux presseurs après la pose de chaque couche. Les rubans isolants actuellement utilisés sont des rubans pré-imprégnés qu'il est nécessaire de réchauffer de quelques dizaines de degrés pour leur apporter, en cours de pose, une viscosité nécessaire à leur glissement naturel sur le conducteur, ou sur la spire du ruban déjà posée, en utilisant ce film résineux comme lubrifiant. Ce glissement naturel du ruban évite alors des problèmes de foisonnement du ruban nuisibles au calibrage du conducteur.In large electric machines, the technique of insulating the conductors consists in winding one or more insulating tapes in several successive layers in a helical pitch, then in calibrating the dimensions of the conductor by means of pressure rollers after the laying of each layer. The currently used insulating tapes are pre-impregnated tapes which need to be warmed up by a few tens of degrees to give them, during installation, a viscosity necessary for their natural sliding on the conductor, or on the turn of the ribbon. installed, using this resinous film as a lubricant. This natural sliding of the ribbon then avoids problems of swelling of the ribbon which are harmful to the calibration of the conductor.

Dans les enrubanneuses connues, le réchauffage du ruban est obtenu par un réchauffage direct de la bobine porte-ruban installée sur un dévidoir, et/ou par un réchauffage du conducteur en amont de l'enruban­neuse.In known wrappers, the reheating of the ribbon is obtained by direct reheating of the ribbon reel installed on a reel, and / or by reheating of the conductor upstream of the wrapper.

Le réchauffage du ruban au niveau de la bobine, donc loin du conducteur, crée un problème de pégosité, le film résineux ayant tendance à couler avant l'opération de pose proprement dite.The reheating of the tape at the level of the reel, therefore far from the conductor, creates a tackiness problem, the resinous film tending to flow before the laying operation proper.

Le réchauffage du ruban par le seul préchauffage du conducteur, en amont de l'enrubanneuse, est insuffisant.The reheating of the ribbon by the sole preheating of the conductor, upstream of the wrapper, is insufficient.

La combinaison de ces deux modes de réchauffage du ruban ne supprime pas l'inconvénient majeur du premier moyen de réchauffage connu, à savoir le foisonnement important entraînant un mauvais calibrage.The combination of these two modes of reheating the ribbon does not eliminate the major drawback of the first known reheating means, namely the significant swelling resulting in poor calibration.

La présente invention a pour but d'obtenir un bon calibrage des dimensions du conducteur en diminuant fortement le foisonnement des rubans, et cette forte diminution du foisonnement est obtenue en réchauffant le ruban le plus près possible du conducteur, donc juste avant l'opération de pose proprement dite.The object of the present invention is to obtain a good calibration of the dimensions of the conductor by greatly reducing the swelling of the ribbons, and this strong reduction in swelling is obtained by heating the ribbon as close as possible to the conductor, therefore just before the operation of proper pose.

La présente invention a pour objet une enrubanneuse pour l'enru­bannage à chaud d'un conducteur électrique, comportant une couronne externe fixe en rotation et recevant en son centre le conducteur à isoler, une couronne tournante roulant à l'intérieur de la couronne fixe et portant au moins une bobine sur laquelle est enroulé un ruban isolant pré-imprégné, l'enrubanneuse ou le conducteur étant animé d'un mouvement de translation qui, associé au mouvement de rotation de la couronne tournante, provoque l'enroulement hélicoïdal du ou des rubans autour du conducteur, caractérisée en ce que la couronne fixe comporte un canal périphérique alimenté en air chaud, et en ce que la couronne tournante est munie d'un ensemble tournant comportant un flasque qui ferme le canal périphérique, au moins un auget tournant dans ce canal périphérique, et au moins une buse chauffante associée, alimentée en air chaud par l'auget, chaque ruban traversant un couloir de transfert de la buse chauffante.The present invention relates to a wrapper for the hot wrapping of an electrical conductor, comprising a crown external fixed in rotation and receiving in its center the conductor to be insulated, a rotating crown rolling inside the fixed crown and carrying at least one coil on which is wound a pre-impregnated insulating tape, the wrapper or the conductor being driven by a translational movement which, associated with the rotational movement of the rotating crown, causes the helical winding of the ribbon (s) around the conductor, characterized in that the fixed crown has a peripheral channel supplied with hot air, and that the rotating crown is provided with a rotating assembly comprising a flange which closes the peripheral channel, at least one bucket rotating in this peripheral channel, and at least one associated heating nozzle, supplied with hot air by the bucket, each ribbon crossing a transfer corridor of the heating nozzle.

D'une manière générale, cette enrubanneuse peut être fixe, et dans ce cas c'est le conducteur qui défile à travers l'enrubanneuse, celui-ci étant guidé et entraîné par deux chariots robotisés, ou cette enruban­neuse peut être mobile en translation, et dans ce cas c'est le conducteur qui est fixe, l'enrubanneuse étant guidée et entraînée par deux chariots robotisés ou entraînée par des galets roulant sur les deux faces du conducteur.In general, this wrapper can be fixed, and in this case it is the conductor who passes through the wrapper, the latter being guided and driven by two robotic carriages, or this wrapper can be movable in translation, and in this case, the conductor is stationary, the wrapper being guided and driven by two robotic carriages or driven by rollers rolling on both sides of the conductor.

Dans tous ces cas, l'enrubanneuse comporte, en aval de la pose du ou des rubans, un dispositif de calibrage constitué rouleaux verticaux et horizontaux.In all these cases, the wrapper comprises, downstream of the laying of the ribbon (s), a calibration device consisting of vertical and horizontal rollers.

Il est décrit ci-après, à titre d'exemple et en référence aux dessins annexés, une enrubanneuse selon l'invention entraînée en trans­lation par deux galets verticaux, le conducteur étant alors fixe.

  • La figure 1 montre une vue partielle en perspective d'une enrubanneuse selon l'invention.
  • La figure 2 montre une coupe partielle de cette enrubanneuse, selon le plan vertical principal, une buse étant située dans ce plan vertical, les bobines n'étant pas représentées.
  • La figure 3 montre une vue de face de cette enrubanneuse, l'ensemble tournant ayant effectué environ un quart de tour par rapport à la figure 1.
It is described below, by way of example and with reference to the accompanying drawings, a wrapper according to the invention driven in translation by two vertical rollers, the conductor then being fixed.
  • Figure 1 shows a partial perspective view of a wrapper according to the invention.
  • Figure 2 shows a partial section of this wrapper, along the main vertical plane, a nozzle being located in this vertical plane, the coils not being shown.
  • FIG. 3 shows a front view of this wrapper, the rotary assembly having performed approximately a quarter of a turn relative to FIG. 1.

La figure 1 montre un conducteur 1 fixe dans l'espace et sur lequel est posé de manière hélicoïdale une première couche d'un ruban 2. Cette figure montre également une machine 10 composée d'une couronne fixe 20, d'une couronne tournante 30, d'un mécanisme d'entraînement 40 de cette couronne tournante 30, d'un ensemble tournant 50 solidaire de la couronne tournante 30, d'un mécanisme d'entraînement 60 de la machine le long du conducteur 1, d'un dispositif de calibrage 70 du ruban posé.Figure 1 shows a conductor 1 fixed in space and on which is helically placed a first layer of a ribbon 2. This figure also shows a machine 10 composed of a fixed crown 20, a rotating crown 30, a drive mechanism 40 for this rotating crown 30, d 'A rotating assembly 50 secured to the rotating ring 30, a drive mechanism 60 of the machine along the conductor 1, a device 70 for calibrating the installed ribbon.

La couronne fixe 20 est suspendue à un palan non représenté se déplaçant librement le long d'un rail. Elle comporte un canal périphéri­que 21 en forme de U, ouvert du côté du flasque 51. Elle est munie de quatre tubes d'alimentation en air chaud 22 tous étant visibles en fig. 3, un tube 22 comportant un élément soufflant 24 et un élément chauffant 23. Chaque tube 22 alimente donc en air chaud le canal périphérique 21.The fixed crown 20 is suspended from a not shown hoist moving freely along a rail. It comprises a U-shaped peripheral channel 21, open on the side of the flange 51. It is provided with four hot air supply tubes 22, all of which are visible in FIG. 3, a tube 22 comprising a blowing element 24 and a heating element 23. Each tube 22 therefore supplies hot air to the peripheral channel 21.

La couronne tournante 30 roule sur des galets 25, cette couronne comportant une denture 31 permettant son entraînement, et un pas de vis interne 32 pour l'entraînement d'une roue 62.The rotating crown 30 rolls on rollers 25, this crown comprising a toothing 31 allowing it to be driven, and an internal screw pitch 32 for driving a wheel 62.

Le mécanisme d'entraînement 40 de la couronne 30 est constitué par un moteur 41 dans l'axe duquel est monté un pignon 42. Deux poulies 44, 45 portent une courroie 43 crantée extérieurement, cette courroie étant entraînée par le pignon 42 et elle entraîne elle-même la denture 31 de la couronne 30.The drive mechanism 40 of the crown 30 is constituted by a motor 41 in the axis of which is mounted a pinion 42. Two pulleys 44, 45 carry an externally toothed belt 43, this belt being driven by the pinion 42 and it drives itself the toothing 31 of the crown 30.

L'ensemble tournant 50 est fixé sur la couronne tournante 30 et il comporte un flasque 51 qui ferme le canal 21.The rotating assembly 50 is fixed to the rotating crown 30 and it includes a flange 51 which closes the channel 21.

Ce flasque 51 reçoit deux axes 52 sur chacun desquels est montée une bobine 53 port-ruban. La figure 3 montre que la bobine 53 est main­tenue sur l'axe 52 par l'intermédiaire d'un bouton moleté "quart de tour" 53A et plus ou moins freinée sur l'axe 52 par un écrou moleté 53B qui régle la tension d'un ressort 53C.This flange 51 receives two axes 52 on each of which is mounted a ribbon-carrying reel 53. FIG. 3 shows that the coil 53 is held on the axis 52 by means of a knurled "quarter-turn" button 53A and more or less braked on the axis 52 by a knurled nut 53B which regulates the tension d 'a spring 53C.

Ce flasque 51 comporte deux galets de guidage 54 et deux buses de chauffage 55, un seul galet et une seule buse étant représentée dans cette figure 1. Ce galet 54 permet d'orienter le ruban dans un couloir de transfert 56 de la buse 55, chaque ruban est donc tendu entre le conduc­teur 1 et le galet 54, et chaque couloir de transfert 56 s'étend depuis le galet de guidage 54 monté sur le flasque 51 jusqu'au niveau du conduc­teur 1.This flange 51 comprises two guide rollers 54 and two heating nozzles 55, a single roller and a single nozzle being shown in this FIG. 1. This roller 54 makes it possible to orient the ribbon in a transfer passage 56 of the nozzle 55, each strip is therefore stretched between the conductor 1 and the roller 54, and each transfer passage 56 extends from the guide roller 54 mounted on the flange 51 to the level of the conductor 1.

La buse 55 reçoit son air chaud d'un auget 57, visible en figure 2, solidaire du flasque 51 et tournant ainsi dans le canal 21.The nozzle 55 receives its hot air from a trough 57, visible in FIG. 2, secured to the flange 51 and thus rotating in the channel 21.

Le mécanisme d'entraînement 60 de l'enrubanneuse 10 le long du conducteur, est constitué par deux galets 61 puis par la roue 62 entraînée par le filetage 32 de la couronne tournante 30, par une autre roue 63 entraînée par la roue 62, cette roue 63 comportant de chaque côté une denture conique 64 engrénant avec une denture conique 65 d'un galet 61, les deux galets 61 roulant sur les faces du conducteur 1.The drive mechanism 60 of the wrapper 10 along the conductor, is constituted by two rollers 61 then by the wheel 62 driven by the thread 32 of the rotating ring 30, by another wheel 63 driven by the wheel 62, this wheel 63 comprising on each side a conical toothing 64 meshing with a conical toothing 65 of a roller 61, the two rollers 61 rolling on the faces of the conductor 1.

Bien entendu, dans le cas où cette enrubanneuse est entraînée par deux chariots robotisés, ce mécanisme d'entraînement 60 n'est plus nécessaire.Of course, in the case where this wrapper is driven by two robotic carriages, this drive mechanism 60 is no longer necessary.

En aval de la pose des rubans, est installé un dispositif de calibrage 70 constitué de quatre rouleaux, deux rouleaux verticaux 71 et deux rouleaux horizontaux 72. Bien entendu on peut prévoir juste en amont de ce dispositif de calibrage, un moyen de réchauffage du conducteur afin d'obtenir un calibrage encore plus satisfaisant.Downstream of the laying of the ribbons, a calibration device 70 is installed, consisting of four rollers, two vertical rollers 71 and two horizontal rollers 72. Of course, a means of heating the conductor can be provided just upstream of this calibration device. in order to obtain an even more satisfactory calibration.

Ces quatre rouleaux sont entraînés par un moteur 73, puis par l'intermédiaire d'un différentiel 75 pour les rouleaux verticaux 71 et par l'intermédiaire d'un mécanisme approprié non représenté, pour les rouleaux horizontaux 72. Les entraxes respectifs des rouleaux verticaux et des rouleaux horizontaux sont réglables afin d'assurer un calibrage des dimensions extérieures du conducteur enrubanné, et ceci pour chaque couche.These four rollers are driven by a motor 73, then by means of a differential 75 for the vertical rollers 71 and by means of a suitable mechanism not shown, for the horizontal rollers 72. The respective centers of the vertical rollers and horizontal rollers are adjustable to ensure a calibration of the external dimensions of the wrapped conductor, and this for each layer.

La figure 2 montre un auget 57, qui collecte l'air chaud du canal 21 pour l'injecter dans le couloir de transfert 56 de la buse 55.FIG. 2 shows a trough 57, which collects the hot air from the channel 21 to inject it into the transfer passage 56 of the nozzle 55.

Cette figure 2 montre également un bâti arrière 29 solidaire de la couronne fixe 20 et un bâti 79 solidaire du bâti 29 et supportant le dispositif de calibrage 70. Ce bâti 79 assure donc le guidage des rouleaux 71, 72 mais aussi le guidage des galets 61. Bien entendu les guidages des roues 62 et 63, non représentés, sont solidaires du bâti 79. Deux molettes 72A assurent le réglage de l'entraxe des rouleaux 72, deux autres molettes, non représentées, assurant le réglage de l'entraxe des rouleaux 71.This FIG. 2 also shows a rear frame 29 secured to the fixed crown 20 and a frame 79 secured to the frame 29 and supporting the calibration device 70. This frame 79 therefore ensures the guiding of the rollers 71, 72 but also the guiding of the rollers 61 Of course the guides of the wheels 62 and 63, not shown, are integral with the frame 79. Two knobs 72A ensure the adjustment of the center distance of the rollers 72, two other knobs, not shown, ensuring the adjustment of the center distance of the rollers 71.

La figure 3 montre de manière claire, que l'air chaud provenant des tubes 22 est projeté dans le canal 21 à l'encontre des augets 57 car ceux-ci tournent dans le sens horaire. Ceci provoque une addition des vitesses d'écoulement de l'air chaud, la vitesse d'écoulement V4 dans un couloir 56 étant la somme des vitesses V1, V2, V3, V1 étant la vitesse d'entrée de l'air ambiant dans un élément soufflant 24, V2 étant la vitesse d'éjection de l'air chaud dans le canal 21, et V3 étant la vitesse circonférentielle d'un auget dans le canal.Figure 3 clearly shows that the hot air from the tubes 22 is projected into the channel 21 against the buckets 57 because these rotate clockwise. This causes an addition of the flow rates of the hot air, the flow speed V4 in a corridor 56 being the sum of the speeds V1, V2, V3, V1 being the speed of entry of the ambient air into a blowing element 24, V2 being the speed of ejection of the hot air into the channel 21, and V3 being the circumferential speed of a trough in the channel.

Toute augmentation de la vitesse de déplacement de l'enrubanneuse provoque une augmentation de la vitesse de défilement du ruban dans un couloir de transfert, mais aussi une augmentation de la vitesse d'écoulement du flux gazeux dans le couloir de transfert, la régulation de la température du ruban étant alors assurée quelle que soit la vitesse de déplacement de l'enrubanneuse.Any increase in the speed of movement of the wrapper causes an increase in the speed of travel of the ribbon in a transfer corridor, but also an increase in the speed of flow of the gas flow in the transfer corridor, the regulation of the ribbon temperature then being ensured regardless of the speed of movement of the wrapper.

Une opération d'enrubannage s'effectue de la manière suivante :
- on place l'enrubanneuse à l'extrémité du conducteur,
- on introduit chaque ruban dans un couloir de transfer de la buse correspondante,
- on fixe les rubans sur le conducteur,
- on met en marche les éléments soufflants puis les éléments chauffants pour chauffer le couloir de tranfert, une sonde interdisant la mise en rotation de l'enrubanneuse tant que la montée en température du couloir de transfert n'est pas satisfaisante,
- dès que la bonne température du couloir est atteinte, on alimente les moteurs 41 et 73.A wrapping operation is carried out as follows:
- the wrapper is placed at the end of the conductor,
each ribbon is introduced into a transfer corridor of the corresponding nozzle,
- the ribbons are fixed on the conductor,
the blowing elements are then switched on, then the heating elements to heat the transfer corridor, a probe prohibiting the rotation of the wrapper as long as the temperature rise in the transfer corridor is not satisfactory,
- as soon as the correct corridor temperature is reached, the motors 41 and 73 are supplied.

Le moteur 41 assure la rotation de la couronne 30 donc la rotation du flasque 51 qui enroule les rubans autour du conducteur, et la rotation des galets 61 qui entraîne l'enrubanneuse 10 le long du conducteur. Les rubans sont alors enroulés selon un pas hélicoïdal.The motor 41 ensures the rotation of the crown 30 therefore the rotation of the flange 51 which wraps the ribbons around the conductor, and the rotation of the rollers 61 which drives the wrapper 10 along the conductor. The ribbons are then wound in a helical pitch.

Le moteur 73 assure la rotation des quatres rouleaux de calibrage qui complètent éventuellement l'action d'entraînement des galets 61 mais qui assurent surtout un calibrage des dimensions extérieurs du conducteur.The motor 73 rotates the four calibration rollers which possibly complete the drive action of the rollers 61 but which above all ensure a calibration of the external dimensions of the conductor.
