Description
La présente invention a pour objet un dispositif de guidage de quartes réalisées sur un premier ensemble de toronnage puis transférées dans une filière de commettage placée avant un deuxième ensemble de toronnage, comprenant une grille de répartition de quartes à la sortie du premier ensemble de toronnage et des moyens de guidage placés entre la grille de répartition et la filiere de commettage.The subject of the present invention is a device for guiding quarters produced on a first stranding set then transferred to a committing die placed before a second stranding set, comprising a grid for distributing quarters at the outlet of the first stranding set and guide means placed between the distribution grid and the committing die.
Ce dispositif permet de toronner de manière régulière un câble pour éviter la création de zones non toronnées, c'est-à-dire parallèles à l'axe principal du câble, qui déséquilibrent géométriquement etélectriquement ledit câble, en particulier un câble de télécommunication. On sait que pour toronner des câbles, en particulier des câbles télephoniques, une des techniques actuelles consiste à effectuer le toronnage sur une machine dite ""machine SZ" qui torsade ce câble alternativement dans un sens et dans l'autre, sans théoriquement ne jamais laisser apparaitre de zones où les fils sont parallèles à l'axe principal du câble.This device makes it possible to regularly strand a cable to avoid the creation of non-stranded zones, that is to say parallel to the main axis of the cable, which geometrically and electrically unbalance said cable, in particular a telecommunication cable. We know that to strand cables, in particular telephone cables, one of the current techniques consists in stranding on a machine called "" SZ machine "which twists this cable alternately in one direction and in the other, without theoretically never reveal areas where the wires are parallel to the main axis of the cable.
On peut, par exemple, fabriquer sur une telle machine, un câble possédant quatorze groupes de quatre fils qui seront toronnés dans un premier ensemble de toronnage en vue de former quatorze quartes.One can, for example, manufacture on such a machine, a cable having fourteen groups of four wires which will be stranded in a first stranding assembly in order to form fourteen fourths.
Ces quatorze quartes torsadées sont dirigées dans une grille de répartition et sont ensuite regroupées par une filière de commettage pour former le câble proprement dit qui sera ensuite guipé par un ruban pour éviter le déquartage, torsadé à nouveau suivant le principe ""SZ" dans un deuxième ensemble de toronnage puis enroulé sur une bobine réceptrice, avant d'être transféré sur une autre machine.These fourteen twisted quartes are directed in a distribution grid and are then grouped together by a committing die to form the cable proper which will then be wrapped with a ribbon to avoid the quartering, twisted again according to the "" SZ "principle in a second stranding assembly then wound on a take-up reel, before being transferred to another machine.
Au cours du passage de chaque quarte, entre la grille de répartition et la filière de commettage, certaines d'entre elles se gênent, favorisant ainsi le déquartage, c'est-à-dire l'absence de toronnage sur des distances notoires, qui provoque des déséquilibres géométriques et électriques laissant apparaitre à l'utilisation des phénomènes de diaphonie.During the passage of each quarter, between the distribution grid and the committing channel, some of them hinder each other, thus favoring the de-quartering, that is to say the absence of stranding over known distances, which causes geometric and electrical imbalances letting appear with the use of the crosstalk phenomena.
On connaît par le document FR-A-1.602.865 une installation de fabrication de câbles utilisant un collecteur placé entre une grille de répartition et une filière, mais ce collecteur ne sépare pas des quartes extérieures et des quartes intérieures.Document FR-A-1,602,865 discloses a cable manufacturing installation using a collector placed between a distribution grid and a die, but this collector does not separate outside quarters and inside quarters.
La présente invention permet de remédier à cet inconvénient en proposant l'adjonction d'une grille de guidage ou d'un c6ne de guidage permettant de bien séparer les quartes avant leur passage dans la filière de commettage.The present invention makes it possible to remedy this drawback by proposing the addition of a guide grid or a guide cone making it possible to separate the quarters well before they pass through the committing die.
Le dispositif de guidage selon l'invention est caractérisé en ce que les moyens de guidage séparent des quartes extérieures et des quartes intérieures.The guiding device according to the invention is characterized in that the guiding means separate outside quarters and inside quarters.
Avantageusement, les moyens de guidage sont une grille de guidage comportant en son centre, des orifices de passage munis de pastilles en matière céramique pour guider les quartes intérieures, et à sa periphérie des supports curvilignes en matière céramique pour guider les quartes extérieures.Advantageously, the guide means are a guide grid comprising, in its center, passage orifices provided with pellets of ceramic material to guide the inner quarters, and at its periphery curvilinear supports in ceramic material to guide the outer quarters.
Avantageusement les moyens de guidage sont un cône de guidage fixé dans la grille de répartition et séparant les quartes intérieures des quartes extérieures, les quartes intérieures étant guidées par une partie conique intérieure du cône de guidage.Advantageously, the guide means are a guide cone fixed in the distribution grid and separating the interior quarters from the exterior quarters, the interior quarters being guided by an interior conical part of the guide cone.
Il est décrit ci-après, à titre d'exemple et en référence aux figures du dessin annexé un dispositif de guidage selon l'invention utilisé dans la fabrication d'un câble téléphonique comportant quatorze quartes. Dans ce cas particulier on emploie cent douze bobines connectées par paires pour effectuer un changement automatique quand cela s'impose; il rentre donc cinquante six fils dans un premier ensemble de toronnage qui produira quatorze quartes. Ces quatorze quartes rentrent dans un deuxième ensemble de toronnage qui produira le câble téléphonique proprement dit.

Les quartes 11 ainsi formées, passent dans un dispositif de guidage 18 comprenant une grille de répartition 6 et une grille de guidage 7, puis elles sont regroupées dans une filière de commettage 8. Le câble 12 ainsi formé est guipé dans un ensemble de guipage 9, toronné dans le deuxieme ensemble 13 de toronnage comprenant une première tête de toronnage 14 et une deuxième tête de toronnage 15, tiré par un cabestan 16 et enroulé sur une bobine 17. Cette bobine sera ensuite transferée sur une autre machine pour faire subir au câble d'autres opérations.The
Dans la figure 2, on distingue le dispositif de guidage 18 comprenant la grille de répartition 6 munie d'orifices 22 de passage de quartes 11, la grille de guidage 7 munie de quatre orifices centraux 20 et de dix supports curvilignes 21, de passage des quartes 11. On distingue également la filière de commettage 8 qui regroupe les quatorze quartes 11 formant le câble 12, c'est-à-dire dix quartes extérieures IIA et quatre quartes intérieures 11 B.In FIG. 2, a distinction is made between the
Dans la figure 3, on voit un autre dispositif de guidage 18 comprenant la grille de répartition 6 munie d'orifices 23 de passage des dix quartes extérieures 11 A, un cône de guidage 24 fixé dans la grille de répartition 6 à l'intérieur duquel passent les quatre quartes interieures 11 B. On distingue également la filière de commettage 8 qui regroupe les quatorze quartes 11 formant le câble 12.In FIG. 3, we see another
La figure 4 montre que les dix quartes extérieures 11A sont guidées par l'extérieur du cône 24 et que les quatre quartes intérieures 11 B sont guidées par une surface intérieure conique 25 du cône 24.FIG. 4 shows that the ten
Sans sortir du cadre de l'invention, le dispositif de guidage peut bien sûr comporter plus ou moins d'orifices de passages de quartes, pour se monter sur une machine fabriquant d'autres types de câbles.Without departing from the scope of the invention, the guide device can of course comprise more or less orifices for the passage of fourths, for mounting on a machine manufacturing other types of cables.
