Description
L'invention concerne un dispositif d'entraînement par traction d'un matériau long à section sensiblement constante, tel que fil, câble, gaine ou feuillard comprenant deux surfaces mobiles en synchronisme et se déplaçant parallèlement l'une à l'autre sur une longueur importante par rapport à leur écartement de manière à enserrer entre elles le matériau long à entraîner, lesdites surfaces comprenant sur leurs faces qui sont en regard dans cette zone de déplacement parallèle des saillies créant sur le matériau long entraîné des alternances de points de compression et de zones libres, les saillies d'au moins une des surfaces étant partiellement déformables élastiquement.The invention relates to a device for driving by traction a long material of substantially constant cross section, such as wire, cable, sheath or strip comprising two surfaces which move in synchronism and move parallel to each other over a length. large with respect to their spacing so as to enclose between them the long material to be driven, said surfaces comprising on their faces which are opposite in this zone of parallel displacement of the projections creating on the long driven material alternating compression points and free zones, the projections of at least one of the surfaces being partially elastically deformable.
L'entraînement d'un matériau long à section constante est difficile à mettre en oeuvre de manière sûre et répétitive, sans glissement, et avec une précision élevée. Ces qualités sont cependant requises lorsque, par exemple, le dispositif d'entraînement est destiné à alimenter une machine de coupe devant fournir des longueurs précises du matériau long.The drive of a long material with constant section is difficult to implement in a safe and repetitive manner, without slipping, and with high precision. These qualities are however required when, for example, the drive device is intended to supply a cutting machine which has to supply precise lengths of the long material.
On a proposé, pour résoudre ce problème, une machine utilisant deux pinces alternées montées sur câble. Cette machine permet d'obtenir le résultat voulu, avec une cadence convenable, mais est encombrante, compliquée et coûteuse. Son encombrement ne permet pas, en particulier, de l'utiliser directement avec une table tournante de montage.To solve this problem, a machine has been proposed using two alternating clamps mounted on a cable. This machine makes it possible to obtain the desired result, with a suitable rate, but is bulky, complicated and expensive. Its size does not allow, in particular, to use it directly with a rotary assembly table.
On connaît un autre dispositif constitué de deux courroies parallèles dont une au moins est entraînée et entre lesquelles le matériau est serré. Ce dispositif est d'un prix de revient et d'un encombrement réduits, mais ne permet pas d'obtenir un entraînement sûr, sans à - coups ni bourrage, sans glissement et avec une grande précision. Ces défauts sont dus au fait que le matériau long passe entre deux rouleaux opposés des courroies dont l'écartement a une cote finie. Dès que le matériau long présente une augmentation de section, par exemple due à une déformation, une boursouflure, un défaut de surface, etc., l'arrivée de cette section accrue entre les rouleaux produit un bourrage, pouvant aller jusqu'à un blocage de l'appareil. Si on donne du jeu à l'un des rouleaux par rapport à l'autre, le serrage du matériau long devient insuffisant et il se produit des glissements.Another device is known which consists of two parallel belts of which at least one is driven and between which the material is clamped. This device is of reduced cost and size, but does not make it possible to obtain a safe drive, without jerks or stuffing, without sliding and with great precision. These defects are due to the fact that the long material passes between two opposite rollers belts whose spacing has a finite dimension. As soon as the long material has an increase in cross-section, for example due to deformation, blistering, a surface defect, etc., the arrival of this increased cross-section between the rollers produces a blockage, which can go as far as blocking of the device. If one of the rollers is given clearance relative to the other, the tightening of the long material becomes insufficient and slipping occurs.
Un autre appareil connu est constitué de deux molettes en regard l'une de l'autre et dont l'une est motorisée. On retrouve les inconvénients précédents dus à la cote finie existant entre les molettes avec, en outre l'inconvénient d'un marquage de la surface du matériau long par les molettes.Another known device consists of two knobs facing each other and one of which is motorized. We find the previous drawbacks due to the finite dimension existing between the rollers with, in addition the drawback of marking the surface of the long material by the rollers.
On connaît enfin, par DE-B-1.114.690, un dispositif d'entraînement pour du tissu dans une machine à coudre, comprenant deux bandes sans fin crantées se déplaçant parallèlement l'une à l'autre sur une grande partie de leur longueur en créant sur le tissu déplacé des alternances de points de compression et de zones libres. Les crans des bandes sans fin sont formés par des dents d'une seule pièce avec la bande, donc élastiques. Dans ce dispositif connu, pour permettre l'introduction de plusieurs couches de tissu sans bourrage et assurer un entraînement sûr, on prévoit de pouvoir faire pivoter une des bandes sans fin, avec ses pignons et poulies, par rapport à l'autre bande. Un tel dispositif est de construction onéreuse et fragile.Finally, from DE-B-1,114,690, a drive device for fabric in a sewing machine is known, comprising two notched endless bands moving parallel to one another over a large part of their length by creating alternating compression points and free zones on the displaced fabric. The notches of the endless bands are formed by teeth in one piece with the band, therefore elastic. In this known device, to allow the introduction of several layers of fabric without tamping and ensuring a safe drive, provision is made to be able to rotate one of the endless bands, with its pinions and pulleys, relative to the other band. Such a device is of expensive and fragile construction.
La présente invention vise à fournir un nouveau dispositif ne présentant pas les inconvénients des dispositifs connus, qui soit simple, solide, économique et peu encombrant, qui assure un entraînement précis même avec des forces de traction élevées et à grande vitesse, sans risque de détérioration de la superficie du matériau long.The present invention aims to provide a new device which does not have the drawbacks of known devices, which is simple, solid, economical and compact, which ensures precise driving even with high tensile forces and at high speed, without risk of deterioration. of the area of the long material.
Ce but est atteint, conformément à l'invention, grâce au fait qu'une seconde surface est constituée par le fond muni de saillies, par exemple moleté, d'une gorge centrale d'un pignon engrenant avec les saillies d'une première surface.This object is achieved, in accordance with the invention, thanks to the fact that a second surface is constituted by the bottom provided with projections, for example knurled, of a central groove of a pinion meshing with the projections of a first surface. .
L'entraînement du matériau long sur une longueur importante entre deux surfaces le pressant en un grand nombre de points, associé à la synchronisation des surfaces, se fait sans glissement possible, sur toute la longueur de la zone de parallélisme des deux surfaces. La déformabilité des saillies d'au moins une des surfaces permet d'absorber toutes les variations régionales de section sans relâcher la pression des saillies sur les autres sections du matériau long, donc sans produire aucun glissement. Cette déformabilité limite en outre les pressions ponctuelles en évitant ainsi de déformer ou marquer le matériau.The entrainment of the long material over a significant length between two surfaces pressing it at a large number of points, associated with the synchronization of the surfaces, is done without possible sliding, over the entire length of the zone of parallelism of the two surfaces. The deformability of the projections of at least one of the surfaces makes it possible to absorb all the regional variations in section without releasing the pressure of the projections on the other sections of the long material, therefore without producing any slippage. This deformability further limits the point pressures, thus avoiding deforming or marking the material.
On peut prévoir que les surfaces sont entraînées par un pignon moteur indépendant ayant une circonférence plusieurs fois plus courte que la longueur de la zone de déplacement parallèle desdites surfaces, ledit pignon moteur étant monté directement en bout d'arbre du moteur, ce qui assure une force de traction importante sur le matériau.Provision may be made for the surfaces to be driven by an independent driving pinion having a circumference several times shorter than the length of the zone of parallel movement of said surfaces, said driving pinion being mounted directly at the end of the motor shaft, which ensures a high tensile force on the material.
Avantageusement, la première surface est constituée par une bande sans fin portant des crans sur sa surface extérieure.Advantageously, the first surface is formed by an endless band carrying notches on its outer surface.
les éléments mobiles étant parfaitement synchronisés et l'entraînement se produisant sans glissement, une forme de réalisation de l'invention prévoit qu'un des éléments mobiles est relié à un dispositif de mesure de longueur, par exemple par comptage d'impulsions.the movable elements being perfectly synchronized and the drive occurring without sliding, an embodiment of the invention provides that one of the movable elements is connected to a length measuring device, for example by counting pulses.
On peut par exemple prévoir que le dispositif de mesure comprend un émetteur d'impulsions relié à au moins un détecteur de passage des saillies d'une des surfaces. L'utilisation de plusieurs détecteurs permet d'augmenter la précision de mesure par diminution du pas apparent.One can for example provide that the measuring device comprises a pulse emitter connected to at least one detector for passage of the projections of one of the surfaces. The use of several detectors makes it possible to increase the measurement accuracy by reducing the apparent pitch.

Dans la forme de réalisation des figures 1 à 3, le dispositif selon l'invention comprend une bande sans fin 1 tendue sur des rouleaux 2, 3, 4, 5 et dont la surface extérieure porte des crans 6 déformables élastiquement. Entre deux rouleaux 2 et 5, la bande 1 est serrée contre un pignon moteur 7 dont les dents 8 engrènent avec les crans 6 de la bande 1. Le pignon moteur 7 comporte une gorge centrale 9 dont le fond 10 est moleté.In the embodiment of Figures 1 to 3, the device according to the invention comprises an
Le matériau à transporter 11, par exemple du fil électrique, est amené sur le rouleau d'entrée 2 qui est en avant du premier point de contact entre la bande 1 et le pignon moteur 7 afin de ne pas créer de point de passage de cote finie. Le fil 11 est saisi et transporté contre le fond moleté 10 de la gorge 9 du pignon 7, en étant maintenu par points par les crans 6 de la bande 1, dans toute la zone de recouvrement de la bande 1 autour du pignon 6. Le fil 11 quitte cette zone de recouvrement avant le dernier rouleau 5 afin de ne pas créer de point de passage de cote finie.The material to be transported 11, for example electric wire, is brought to the
