Description

Lorsqu'on désire dérouler d'une bobine le fil qu'elle contient, on place la bobine sur un dérouleur qui est généralement freiné afin de donner au fil une certaine tension.When you want to unwind the thread it contains from a reel, place the reel on an unwinder which is generally braked to give the thread some tension.

Un tel mode opératoire est parfaitement satisfaisant pour les.fils peu fragiles enroulés sur de petites bobines. Par contre, s'il s'agit de fils fragiles, en raison de leur finesse et/ou de leur nature (fibres de verre), la tension appliquée pendant leur déroulement doit être faible et très régulière, et cela même lorsqu'ils sont déroulés de bobines grosses et lourdes. Or, dans un tel cas, les irrégularités provoquées par les frottements, les balourds et l'inertie des bobines rendent inutilisable un simple freinage de celles-ci.Such a procedure is perfectly satisfactory for the weak bristles wound on small coils. On the other hand, in the case of fragile yarns, because of their fineness and / or their nature (glass fibers), the tension applied during their unwinding must be low and very regular, even when they are unwound large and heavy coils. However, in such a case, the irregularities caused by friction, unbalance and the inertia of the coils make it impossible to simply brake them.

Dans le but de permettre un déroulement parfait et sans risque de rupture d'un fil fragile issu d'une bobine lourde, il est connu d'utiliser un dispositif de déroulement comprenant un mécanisme susceptible d'qpliquer un couple moteur ou résistant à la bobine en rotation au cours du déroulement du fil qu'elle contient, ce mécanisme, composé d'un moteur d'entraînement et d'un frein de ralentissement de la bobine, étant commandé à partir d'un capteur sensible à la tension du fil à la sortie de la bobine de manière à maintenir constante ladite tension. Un tel dispositif peut assurer une régulation très fine de la tension du fil par asservissement de la vitesse de rotation de la bobine réalisé de manière active, et non par simple freinage.In order to allow a perfect unwinding and without risk of breaking a fragile wire from a heavy coil, it is known to use an unwinding device comprising a mechanism capable of applying a motor torque or resistant to the coil in rotation during the unwinding of the thread that it contains, this mechanism, composed of a drive motor and a reel slowdown brake, being controlled from a sensor sensitive to the tension of the thread to the output of the coil so as to maintain constant said voltage. Such a device can ensure very fine regulation of the thread tension by slaving the speed of rotation of the coil produced in an active manner, and not by simple braking.

Selon l'invention, seul le moteur dudit mécanisme est commandé à partir du capteur précité, tandis que le frein applique à la bobine un couple de freinage constant. Il convient de régler le couple constant appliqué en permanence par le frein à la bobine à une valeur supérieure à la valeur maximale de l'ensemble des couples parasites que subit la bobine dans sa rotation du fait des imperfections de structure ou de montage qu'elle comporte inévitablement, de manière que ce soit le couple de freinage volontairement appliqué à la bobine qui soit prépondérant et définisse le couple résistant global qui s'exerce sur la bobine, y compris le couple nécessaire pour vaincre l'inertie de la bobine pendant la décélération.According to the invention, only the motor of said mechanism is controlled from the aforementioned sensor, while the brake applies to the coil a constant braking torque. The constant torque permanently applied by the brake to the coil should be adjusted to a value greater than the maximum value of all the parasitic torques which the coil undergoes in its rotation due to structural or mounting imperfections that it inevitably involves so that it is the braking torque voluntarily applied to the coil which is predominant and defines the overall resistive torque exerted on the coil, including the torque necessary to overcome the inertia of the coil during deceleration.

Le moteur peut être alimenté par un variateur de vitesse électronique à un quadrant piloté par le capteur de tension du fil, ce qui est une solution avantageuse, car le variateur à un quadrant est un appareil relativement simple et peu coûteux. Par ailleurs, la puissance consommée par le frein est en pratique très faible.The motor can be powered by an electronic quadrant speed controller controlled by the thread tension sensor, which is an advantageous solution because the quadrant drive is a relatively simple and inexpensive device. In addition, the power consumed by the brake is in practice very low.

La description qui va suivre, en regard du dessin annexé à titre d'exemple non limitatif, permettra de bien comprendre comment la présente invention peut être mise en pratique.The description which follows, with reference to the attached drawing by way of nonlimiting example, will make it possible to understand clearly how the present invention can be put into practice.

La figure unique représente schématiquement un dispositif selon l'invention.The single figure schematically represents a device according to the invention.

On voit sur la figure une bobine 1 chargée d'un fil 2 et montée sur un dérouleur 3. A la sortie de la bobine, le fil 2 forme entre deux poulies 4, 5 une boucle 6 passant sur une poulie 7 mobile. Celle-ci appartient à un pantin 8 servant à mesurer la tension Q du fil 2 et constitué par un bras pivotant 9 autour d'un point 9a et un ressort de traction 10 tendant à augmenter l'ampleur de la boucle 6. Le bras 9 est couplé, par l'intermédiaire d'engrenage 11, 12, à un potentiomètre 13 connecté à l'entrée d'un variateur de vitesse électronique 14 à.un quadrant dont la sortie alimente un moteur 15 relié au dérouleur 3 par une courroie 16.We see in the figure a coil 1 loaded with a wire 2 and mounted on an unwinder 3. At the exit of the coil, the wire 2 forms between two pulleys 4, 5 a loop 6 passing over a movable pulley 7. This belongs to a puppet 8 used to measure the tension Q of the wire 2 and constituted by a pivoting arm 9 around a point 9a and a tension spring 10 tending to increase the amplitude of the loop 6. The arm 9 is coupled, via gear 11, 12, to a potentiometer 13 connected to the input of an electronic speed controller 14 to a quadrant whose output feeds a motor 15 connected to the unwinder 3 by a belt 16 .

Un frein 17 applique en permanence un couple de freinage constant au dérouleur 3.A brake 17 permanently applies a constant braking torque to the unwinder 3.

Lorsque la vitesse de la bobine 1 varie, la poulie 7 du pantin 8 se déplace et commande, par l'intermédiaire de la chaîne d'asservissement 9, 11, 12, 13 et 14, le moteur 15 de manière que le couple moteur qu'il fournit varie en conséquence.When the speed of the reel 1 varies, the pulley 7 of the jaw 8 moves and controls, via the servo chain 9, 11, 12, 13 and 14, the motor 15 so that the motor torque qu 'it provides varies accordingly.

En régime stabilisé, le pantin ne bouge pas et la tension du fil est Q = F, F étant la force du 2 ressort 10. Il suffit de régler F pour ajuster la tension Q.In steady state, the puppet does not move and the thread tension is Q = F, F being the force of the 2 spring 10. It suffices to adjust F to adjust the tension Q.

Lorsque la vitesse linéaire de déroulement du fil 2 n'est pas constante ou lorsque la bobine 1 est de mauvaise qualité, les irrégularités correspondantes sont compensées par de faibles déplacements du pantin 8.When the linear speed of unwinding of the wire 2 is not constant or when the reel 1 is of poor quality, the corresponding irregularities are compensated for by small movements of the puppet 8.

L'inertie et le couple de frottement du pantin 8 risquent d'engendrer des variations de la tension Q du fil. Pour rendre ces variations négligeables, il convient de réduire le plus possible l'importance de ces paramètres de fabrication affectant le pantin.The inertia and the friction torque of the puppet 8 risk generating variations in the tension Q of the wire. To make these variations negligible, the importance of these manufacturing parameters affecting the puppet should be reduced as much as possible.

En fonctionnement, le couple moteur combat le couple de freinage, ce dernier étant réglé à une valeur supérieure à la valeur maximale de l'ensemble des couples parasites affectant la bobine 1 en rotation et inhérents à son montage (frottements) et à sa structure (inertie, balourds), de manière à masquer les fluctuations de ces couples parasites. Lorsque le pantin 8 se déplace vers le haut, le couple moteur augmente et, lorsqu'il se déplace vers le bas, le couple moteur diminue, de sorte que le couple résultant appliqué à la bobine par l'ensemble du moteur 15 et du frein 17 se trouve modulé de manière à mantenir la tension du fil 2 constante et égale à la valeur Q = F. 2In operation, the engine torque combats the braking torque, the latter being set to a value greater than the maximum value of all the parasitic torques affecting the coil 1 in rotation and inherent in its mounting (friction) and its structure ( inertia, unbalance), so as to mask the fluctuations of these parasitic couples. When the jack 8 moves up, the engine torque increases and, when it moves down, the engine torque decreases, so that the resulting torque applied to the coil by the assembly of the engine 15 and the brake 17 is modulated so as to keep the thread tension 2 constant and equal to the value Q = F. 2
