Description
La présente invention concerne un dispositif de câblage de fils d'armure autour d'une âme d'un câble, comprenant un plateau tournant muni de bobines de fils d'armure, une grille de répartition tournante entraînée par le plateau, et une filière de câblage regroupant les fils d'armure sur l'âme du câble.The present invention relates to a device for wiring armor wires around a core of a cable, comprising a turntable provided with coils of armor wires, a rotary distribution grid driven by the tray, and a die for wiring grouping the armor wires on the cable core.
Elle concerne également un procédé mis en oeuvre par ce dispositif.It also relates to a method implemented by this device.
Dans les câbleuses-toronneuses assurant le câblage de fils d'armure autour d'une âme centrale d'un câble, les fils sont généralement stockés sur des bobines puis ils sont guidés à travers une grille de répartition tournante avant d'être regroupés par une filière autour de l'âme centrale qui se déplace longitudinalement.In stranding machines ensuring the wiring of armor wires around a central core of a cable, the wires are generally stored on spools and then they are guided through a rotating distribution grid before being grouped by a die around the central core which moves longitudinally.
On connaît, notamment par le document FR-A-2 088 104, un dispositif de câblage dont la grille de répartition tourne de manière uniforme pour câbler hélicoïdalement les fils autour de l'âme centrale. Au cours d'un arrêt de cette câbleuse, l'inertie du plateau tournant continue à entraîner la grille de répartition alors que l'âme centrale est déjà stoppée, car l'inertie du dispositif d'entraînement de l'âme est plus faible que celle du plateau. Il se produit donc un surcâblage des fils d'armure qui écrasent l'âme du câble, et ceci est notamment préjudiciable aux âmes de câbles à fibres optiques. Ce surcâblage est bien entendu rattrapé au redémarrage de la câbleuse, mais il a déjà produit son effet néfaste.Is known, in particular from document FR-A-2 088 104, a wiring device whose distribution grid rotates uniformly to wire the wires helically around the central core. During a shutdown of this stranding machine, the inertia of the turntable continues to drive the distribution grid while the central core is already stopped, because the inertia of the core drive device is lower than that of the plateau. There is therefore an overwiring of the armor wires which crush the core of the cable, and this is particularly detrimental to the cores of optical fiber cables. This overwiring is of course caught up with when the strander is restarted, but it has already produced its harmful effect.
La présente invention permet d'obtenir un arrêt simultané de la grille de répartition et de l'âme du câble pour éviter le surcâblage.The present invention makes it possible to obtain a simultaneous stop of the distribution grid and of the core of the cable to avoid overwiring.
Le dispositif selon l'invention est caractérisé en ce qu'il comprend un accouplement débrayable constitué de deux parties séparables et situé entre le plateau et la grille de répartition, et un frein pour bloquer la grille de répartition.The device according to the invention is characterized in that it comprises a disengageable coupling consisting of two separable parts and located between the plate and the distribution grid, and a brake for blocking the distribution grid.
Cet accouplement peut être, par exemple, un limiteur de couple, un embrayage, ou encore un coupleur électromagnétique.This coupling can be, for example, a torque limiter, a clutch, or even an electromagnetic coupler.
Le procédé selon l'invention, dans lequel on enroule hélicoïdalement des fils d'armure sur une âme d'un câble se déplaçant longitudinalement, est caractérisé en ce que, en cas d'arrêt de l'opération de câblage, on bloque la grille de répartition et on la sépare mécaniquement du plateau tournant pour éviter un surcâblage des fils d'armure sur l'âme immobilisée, ceThe method according to the invention, in which armor wires are helically wound on a core of a cable moving longitudinally, is characterized in that, in the event of the cabling operation being stopped, the grid is blocked distribution and it is mechanically separated from the turntable to avoid overwiring of the armor wires on the immobilized core, this
surcâblage se produisant alors entre la grille de répartition et le plateau tournant entraîné par son inertie.overwiring then occurs between the distribution grid and the turntable driven by its inertia.
Avantageusement, l'immobilisation de l'âme commande le freinage de la grille de répartition.Advantageously, the immobilization of the core controls the braking of the distribution grid.
De préférence, pour redémarrer l'opération de câblage, on tourne le plateau en sens inverse pour rattraper le surcâblage, on desserre le frein de la grille de répartition et, les deux parties étant à nouveau accouplées, on relancePreferably, to restart the wiring operation, we turn the plate in the opposite direction to catch up with the overwiring, we release the brake on the distribution grid and, the two parts being coupled again, we restart
l'opération de câblage en inversant à nouveau la rotation du plateau.the wiring operation by again reversing the rotation of the plate.
Il est décrit ci-après à titre d'exemple et en référence à la figure unique du dessin annexé, un dispositif de câblage selon l'invention.It is described below by way of example and with reference to the single figure of the accompanying drawing, a wiring device according to the invention.
Dans cette figure unique, le dispositif de câblage 1 comprend un plateau tournant 2 sur lequel sont montées des bobines 3 de fils d'armure 11, une grille de répartition tournante 4 séparant les fils 11, et une filière 5 regroupant les fils 11 autour d'une âme 10 pour former un câble 12.In this single figure, the
La grille de répartition 4 est raccordée mécaniquement au plateau tournant 2 par un accouplement 20 composé de deux parties séparables 21, 22, la partie 21 étant raccordée à un tube 30 solidaire du plateau 2, et la partie 22 étant raccordée à la grille de répartition. Avantageusement le diamètre et la longueur du tube central 30 sont calculés pour ne pas produire de déformation permanente des fils d'acier lors du surcâblage. Les deux parties deThe distribution grid 4 is mechanically connected to the turntable 2 by a
l'accouplement sont accouplées pendant l'opération de câblage et désaccouplées au moment du freinage de la grille de répartition car à cet instant, le couple tournant exercé par le plateau est très important. Un frein à disque 40, commandé par l'arrêt de l'avancement du câble, est monté à la périphérie de la grille de répartition.the couplings are coupled during the wiring operation and uncoupled when the distribution grid is braked because at this instant, the rotating torque exerted by the plate is very high. A
Le plateau et l'âme sont entraînés par des moyens mécaniquement indépendants mais reliés néanmoins par un asservissement électrique. L'inertie du moyen d'entraînement du plateau est plus importante que celle du moyen d'entraînement de l'âme.The plate and the core are driven by mechanically independent means but nevertheless connected by an electric control. The inertia of the plate drive means is greater than that of the core drive means.
Une opération de câblage se déroule de la manière suivante: l'âme se déplace longitudinalement et traverse entièrement le dispositif de câblage 1, et le plateau ainsi que la grille de répartition entraînent en rotation les fils d'armure qui s'enroulent alors hélicoïdalement autour de l'âme au niveau de la filière.A wiring operation takes place as follows: the core moves longitudinally and passes entirely through the
Au cours d'un arrêt de l'opération de câblage, l'âme du câble s'immobilise quasiment instantanément du fait de sa faible inertie, et cette immobilisation déclenche, à cet instant précis et par des moyens de commande connus, le serrage du frein de la grille de répartition.During a stopping of the wiring operation, the cable core stops almost instantaneously due to its low inertia, and this immobilization triggers, at this precise moment and by known control means, the tightening of the brake of the distribution grid.
Les fils d'armure sont alors stoppés en rotation entre la grille de répartition et la filière, supprimant ainsi tout surcâblage au niveau de cette filière.The armor wires are then stopped in rotation between the distribution grid and the die, thus eliminating any overwiring at this die.
La grille de repartition étant freinée, l'accouplement sépare mécaniquement celle-ci du plateau qui, du faît de sa grande inertie de rotation, continue à tourner pendant éventuellement plusieurs tours.The distribution grid being braked, the coupling mechanically separates it from the plate which, due to its great rotational inertia, continues to rotate for possibly several turns.
Le surcâblage se trouve alors à cet instant, entre le plateau et la grille de répartition, et l'âme du câble se trouve donc protégée.The overwiring is then at this instant, between the plate and the distribution grid, and the cable core is therefore protected.
La séparation mécanique de la grille et du plateau peut être automatique dans le cas d'un accouplement du type limiteur de couple par exemple, ou commandée par des moyens connus dans le cas d'un accouplement du type embrayage par exemple.The mechanical separation of the grid and the plate can be automatic in the case of a coupling of the torque limiter type for example, or controlled by known means in the case of a coupling of the clutch type for example.
Pour redémarrer l'opération de câblage, on garde serré le frein de la grille de répartition, on fait tourner le plateau en marche lente et en sens inverse pour aligner les fils d'armure, puis à la fin de cette opération, les deux parties de l'accouplement sont accouplees automatiquement dans le cas d'un accouplement du type limiteur de couple, ou de manière commandée dans le cas d'un accouplement du type embrayage. Après avoir desserré le frein de la grille de répartition, on relance l'opération de câblage en démarrant simultanément l'âme du câble et le plateau tournant dont on a bien sûr inversé de nouveau le sens de rotation.To restart the wiring operation, keep the brake on the distribution grid engaged, the plate is rotated in slow motion and in the opposite direction to align the armor wires, then at the end of this operation, the two parts of the coupling are automatically coupled in the in the case of a torque limiter type coupling, or in a controlled manner in the case of a clutch type coupling. After releasing the brake on the distribution grid, the wiring operation is restarted by simultaneously starting the cable core and the turntable, the direction of rotation of which has of course been reversed again.
Sans sortir du cadre de l'invention, ce dispositif et son procédé peuvent s'appliquer à toutes câbleuses-toronneuses enroulant hélicoïdalement des fils sur une âme gainée ou lisse d'un câble électrique à fibres optiques ou autre, et la grille de répartition peut, par exemple, comporter un dispositif de préformation des fils.Without departing from the scope of the invention, this device and its method can be applied to all stranding machines helically winding wires on a sheathed or smooth core of an optical fiber or other electrical cable, and the distribution grid can , for example, include a device for preforming the wires.
