Abstract

Dispositif de bobinage caractérisé par le fait qu'il permet de fabriquer des bobines dont les supports ou carcasses sont pratiquement démunis de toute rigidité. Le dispositif comprend un élément (1) pour la fixation du support non rigide (2) pendant toute l'opération du bobinage. Pour que cette opération devienne possible, un élément (4) nommé système se déplace axialement à celui de la bobine avançant synchroniquement et dans le même sens que le mécanisme dont le bras (5) enroule le fil à bobiner (3) autour du support non rigide (2), ce système (4) possédant deux parties (6 et 7) recouvrant la part bobinée sur deux de ses grandes faces opposées de telle manière que la ou les dernières spires réalisées en cours de fabrication soient au moins recouvertes sur l'ensemble de la largeur du support non rigide (2). Pour éviter l'inconvénient que la bobine en fabrication se mette à vibrer entre les deux parties (6 et 7) du système (4) le support non rigide (2) étant sollicité par la tension du fil à bobiner (3) dont le sens est tournant, il est prévu de monter sur l'une des deux parties (6 ou 7) du système (4) un solénoïde (8) parcouru par un courant électrique formant ainsi un électro-aimant capable d'attirer contre lui le support non rigide (2) supposé construit dans un matériau sensible à un champ magnétique.Winding device characterized in that it makes it possible to manufacture reels whose supports or carcasses are practically devoid of any rigidity. The device comprises an element (1) for fixing the non-rigid support (2) during the entire winding operation. For this operation to become possible, an element (4) called system moves axially to that of the coil advancing synchronously and in the same direction as the mechanism whose arm (5) wraps the spool yarn (3) around the support not rigid (2), this system (4) having two parts (6 and 7) covering the part wound on two of its large opposite faces in such a way that the last turn or turns carried out during manufacture are at least covered on the the entire width of the non-rigid support (2). To avoid the disadvantage that the coil in manufacture starts to vibrate between the two parts (6 and 7) of the system (4) the non-rigid support (2) being stressed by the tension of the thread to be wound (3) whose direction is rotating, it is planned to mount on one of the two parts (6 or 7) of the system (4) a solenoid (8) traversed by an electric current thus forming an electromagnet capable of attracting against it the support not rigid (2) assumed to be constructed of a material sensitive to a magnetic field.

Description

Dispositif de bobinageWinding device
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 present invention relates to 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 sectional view while the bottom image is a plan view.
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 à celui de 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 réalisées 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 suffi srimment 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 to that of 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 whorls 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 rigid 2 whose plane is practically the same as that of the coil which is currently 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 part 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 prévu 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.
