Abstract

Winding device characterized in that it enables to fabricate coils of which the supports or formers are substantially deprived of rigidity. The device comprises an element (1) for fixing the non-rigid support (2) during the whole winding operation. In order to make said operation possible, an element (4) called system is axially displaced with respect to the synchronously fed coil and in the same direction as the mechanism of which the arm (5) winds the wire to be wound (3) around the non-rigid support (2), said system (4) having two parts (6 and 7) covering the wound portion on two of its opposite large faces so that the last turn or turns made during fabrication are at least covered on the width of the non-rigid support (2). To prevent the coil from vibrating during manufacturing between the two parts (6 and 7) of the system (4) while the non-rigid support (2) is acted upon by the tension of the wire to be wound (3) of which the direction is turning, there is provided to mount on one of the two parts (6 or 7) of the system (4) a solenoid (8) through which is circulated an electric current thereby forming an electromagnetic capable of attracting thereagainst the non-rigid support (2) which is supposedly made with a material sensitive to a magnetic field.

Description

La présente invention a pour objet un dispositif de bobinage caractérisé par le fait qu'il permet de fabriquer des bobines en enroulant leurs fils autour de leurs supports ceux-ci étant pratiquement démunis de toute rigidité.The subject of the present invention is a winding device characterized in that it makes it possible to manufacture coils by winding their wires around their supports, these being practically devoid of any rigidity.

Le dessin annexé représente à simple titre d'exemple et non limitatif, une forme d'exécution dans son principe de l'objet de la présente invention.The appended drawing represents by way of example and without limitation, an embodiment in principle of the object of the present invention.

La fig. 1 image du haut en est une vue en coupe alors que l'image du bas en est une vue en plan.Fig. 1 top image is a section view while the bottom image is a plan view.

On connaît du document BE-A 793577 un dispositif de bobinage comprenant un système capable de rendre pratiquement inflexible le support de bobine solicité par les tensions qu'exerce sur lui le fil à bobiner et dont la section du support à cet endroit se trouve être sensiblement dans le plan de la spire en train de se former en cours de fabrication. Ce dispositif comporte deux organes de retenue pouvant se rapprocher et s'éloigner l'un de l'autre et susceptible chacun de maintenir temporairement et alternativement le support de la bobine. Chaque fois que ce support change d'organe de retenue une bobine débitrice est déplacée linéairement perpendiculairement à la direction de déplacement des organes de retenue. L'axe d'une bobine ainsi réalisée est perpendiculaire à la direction de déplacement des organes retenue. Un tel dispositif est complexe et ne permet pas de réaliser de bobines allongées sur des supports flexibles. Le but de la présente invention est de remédier à ces inconvénients.Document BE-A 793577 discloses a winding device comprising a system capable of rendering the reel support solicited practically inflexible by the tensions exerted on it by the winding wire and the section of the support of which is found to be substantially in the plane of the whorl being formed during manufacture. This device comprises two retaining members which can move towards and away from one another and each capable of temporarily and alternately maintaining the support of the coil. Each time this support changes the retaining member, a supply reel is moved linearly perpendicular to the direction of movement of the retaining members. The axis of a coil thus produced is perpendicular to the direction of movement of the selected members. Such a device is complex and does not allow elongated coils to be produced on flexible supports. The object of the present invention is to remedy these drawbacks.

Le dispositif selon l'invention se distingue par les caractéristiques décrites et revendiquées dans ce qui suit.The device according to the invention is distinguished by the characteristics described and claimed in the following.

Le dispositif de bobinage représenté au dessin comprend un élément 1 servant de pince et destiné à positionner puis à fixer le support non rigide 2 pendant le bobinage, l'épaisseur de ce support 2 pouvant être réduite dans la pratique à celle d'une mince feuille de papier.The winding device shown in the drawing comprises an element 1 serving as a clamp and intended to position and then fix the non-rigid support 2 during the winding, the thickness of this support 2 can in practice be reduced to that of a thin sheet of paper.

Pour que le bobinage devienne quelque chose de possible, il est nécessaire de pouvoir rendre inflexible la partie du support non rigide 2 sollicitée par les tensions exercées par le fil à bobiner 3. Dans cet objectif, un élément 4 nommé système est prévu pour se déplacer axialement par rapport à la bobine dont l'avance est synchronisée avec le bras 5 du mécanisme de bobinage à chacune de ses révolutions, cette avance étant commandée par un moteur non représenté. Par les deux parties 6 et 7 du système 4 espacées d'une distance à peine supérieure à l'épaisseur du support non rigide 2 plus deux fois le diamètre du fil à bobiner 3 et recouvrant la partie bobinée de telle manière que la ou les dernières spires réalisée en cours de fabrication soient pour le moins recouvertes sur l'ensemble de la largeur du support non rigide 2, ce système 4 est à même par là et par ses deux parties 6 et 7 de rendre suffisamment inflexible la section du support non rigide 2 dont le plan est pratiquement le même que celui de la spire qui se trouve présentement en cours de fabrication.For the winding to become something possible, it is necessary to be able to make inflexible the part of the non-rigid support 2 stressed by the tensions exerted by the wire to be wound 3. For this purpose, an element 4 called system is provided for moving axially with respect to the coil, the advance of which is synchronized with the arm 5 of the winding mechanism at each of its revolutions, this advance being controlled by a motor not shown. By the two parts 6 and 7 of the system 4 spaced apart by a distance barely greater than the thickness of the non-rigid support 2 plus twice the diameter of the wire to be wound 3 and covering the wound part in such a way that the last turns made during manufacture are at least covered over the entire width of the non-rigid support 2, this system 4 is able thereby and by its two parts 6 and 7 to make the section of the non-rigid support sufficiently inflexible 2, the plane of which is practically the same as that of the coil which is currently in the process of being manufactured.

Au cours de l'opération du bobinage et par le fait que l'épaisseur de la bobine est à peine inférieure à la distance séparant les deux parties 6 et 7 du système 4 cette construction permettant un déplacement libre de ces deux parties 6 et 7 sur la partie du support non rigide 2 déjà bobinée, il en résulte dans ces conditions la possibilité que ce support non rigide 2 sous la tension qu'exerce le fil 3 à chaque révolution se mette dans un mouvement oscillatoire. Pour éviter un tel inconvénient et pour autant que le support non rigide 2 soit pris dans un matériau sensible à l'action magnétique d'un aimant, il est prévue d'emmancher sur l'une des deux parties 6 ou 7 du système 4, un solénoïde 8 parcouru par un courant électrique.During the winding operation and the fact that the thickness of the coil is barely less than the distance separating the two parts 6 and 7 of the system 4, this construction allowing free movement of these two parts 6 and 7 over the part of the non-rigid support 2 already wound, this results in these conditions the possibility that this non-rigid support 2 under the tension exerted by the wire 3 at each revolution is put into an oscillatory movement. To avoid such a drawback and provided that the non-rigid support 2 is caught in a material sensitive to the magnetic action of a magnet, provision is made to fit onto one of the two parts 6 or 7 of the system 4, a solenoid 8 traversed by an electric current.

Chacune des deux parties du système travaille alternativement l'une après l'autre en soutenant le support d'une manière continue et ceci à chaque endroit successif sollicité par la tension du fil tout au long de l'opération du bobinage.Each of the two parts of the system works alternately one after the other by supporting the support in a continuous manner and this at each successive place stressed by the tension of the thread throughout the winding operation.

Dans une variante le système 4 ne possède que la partie entourée par le solénoïde, la force suffisamment grande de l'électro-aimant jouant ici le rôle de la seconde partie du système.In a variant, the system 4 only has the part surrounded by the solenoid, the sufficiently large force of the electromagnet playing here the role of the second part of the system.

Dans une exécution particulière, le système et le mécanisme dont la fonction est d'enrouler le fil à bobiner autour de son support ne se déplacent pas dans un mouvement axial à celui de la bobine alors que le mouvement dans cette même direction est reporté uniquement sur le support de bobine.In a particular embodiment, the system and the mechanism whose function is to wind the thread to be wound around its support do not move in an axial movement to that of the coil while the movement in this same direction is transferred only to the spool holder.

Dans une autre réalisation, le mécanisme porteur du fil à bobiner est fixe alors que le système et le support tournent ensemble sur eux-mêmes ce dernier possédant en plus de son mouvement de rotation un mouvement axial à celui de la bobine.In another embodiment, the carrier mechanism of the winding wire is fixed while the system and the support rotate together on themselves, the latter having in addition to its rotational movement an axial movement to that of the coil.
