Abstract
Description
La présente invention concerne un dispositif nouveau permettant d'enrouler sous forte tension au moins une bande d'un produit allonge, tel que feuillard, fil ou cable, sur un corps cylindrique pouvant être de très grande longueur. The present invention relates to a new device for winding under high tension at least one strip of an elongated product, such as strip, wire or cable, on a cylindrical body which can be very long.
I1 est souvent nécessaire de renforcer les canalisations destines a contenir ou transporter des fluides sous haute pression par des frettes formées par un ou plusieurs enroulements helicoidaux de feuillards, cables ou fils, soit métalliques, soit en verre-résine à haute résistance. La demanderesse a déjà mis au point de nombreux dispositifs permettant d'effectuer de manière contrôlée de tels enroulements et a fait breveter certaines solutions, telle par exemple celle décrite dans son brevet français publié sous le numéro 2.364.846. It is often necessary to reinforce the pipes intended to contain or transport fluids under high pressure by hoops formed by one or more helical windings of strips, cables or wires, either metallic or made of high-resistance glass-resin. The Applicant has already developed numerous devices making it possible to carry out such windings in a controlled manner and has patented certain solutions, such as, for example, that described in its French patent published under number 2,364,846.
Ces dispositifs concernent plutôt des modes de réalisations adaptes à des réalisations bien spécifiques, par exemple l'enroulement d'un feuillard sur un corps fixe vertical, et ne sont donc pas adaptables à d'autres conditions d'enroulement.These devices rather relate to embodiments adapted to very specific embodiments, for example the winding of a strip on a vertical fixed body, and are therefore not adaptable to other winding conditions.
Par ailleurs, dans le cas ou l'on désire effectuer de tels enroulements sur des canalisations de grande longueur fixes en position, il est très utile de pouvoir effectuer cette opération en continu, c'est-à-dire sans arrêt trop long de la machine pour le remplacement d'une bobine vide par une bobine pleine. Les dispositifs connus actuellement et permettant de résoudre partiellement ce problème sont des dispositifs dits "centerless" ou "sans centre" et sont par exemple tels que décrits dans le brevet français nO 1.378.838. De tels dispositifs connues ne permettent cependant pas l'enroulement sous très forte tension et nécessitent par ailleurs un changement de sens de la bande avant enroulement, ce qui est préjudiciable pour certains matériaux. Furthermore, in the case where it is desired to carry out such windings on pipes of great length fixed in position, it is very useful to be able to carry out this operation continuously, that is to say without stopping for too long. machine for replacing an empty coil with a full coil. The devices currently known and which make it possible to partially solve this problem are so-called "centerless" or "centerless" devices and are, for example, as described in French patent No. 1,378,838. Such known devices do not however allow winding under very high tension and also require a change of direction of the strip before winding, which is detrimental for certain materials.
La présente invention concerne un dispositif permettant d'effectuer dans des conditions optimales et très varies l'enroulement contrôlé sous forte tension de produits en bande sur un corps cylindrique, que ce corps soit fixe ou tournant, horizontal ou vertical, court ou long. I1 est caractérisé en ce qu'il comporte au moins une jante en forme d'arc de cercle, cercle ou spirale, placée autour du corps cylindrique à la manière des dispositifs dits "centerless" ou "sans centre", le produit à enrouler patinant sur cette jante avant de s'enrouler sur le corps cylindrique et en ce que la jante-comporte, à son extrémité amont, un dispositif de pré-tension réglable du produit à enrouler. The present invention relates to a device making it possible to carry out, under optimal and very varied conditions, the controlled winding under high tension of strip products on a cylindrical body, whether this body is fixed or rotating, horizontal or vertical, short or long. I1 is characterized in that it comprises at least one rim in the shape of an arc of a circle, circle or spiral, placed around the cylindrical body in the manner of so-called "centerless" or "centerless" devices, the product to be rolled skating on this rim before being wound on the cylindrical body and in that the rim-comprises, at its upstream end, an adjustable pre-tensioning device for the product to be wound.
En outre, selon une caractéristique particulièrement avantageuse, le dispositif de l'invention comporte au moins une couronne auxiliaire de stockage pour la préparation de la bande de remplacement de la bande en cours d'enroulement, ladite couronne étant coaxiale à la jante et au dispositif de soutien de la bande en cours d'enroulement et étant en outre munie de moyens lui permettant de tourner en sens inverse de ladite jante. In addition, according to a particularly advantageous characteristic, the device of the invention comprises at least one auxiliary storage ring for the preparation of the strip for replacing the strip during winding, said ring being coaxial with the rim and with the device. supporting the strip during winding and being further provided with means allowing it to turn in the opposite direction of said rim.
L'invention sera mieux comprise à l'aide de la description suivante d'un exemple de réalisation relatif à une machine d'enroulement sous tres forte tension d'un feuillard sur une conduite tubulaire fixe en position, en référence aux dessins annexes dans lesquels:
- la figure 1 est une vue latérale schématique de la machine d'enroulement de bandes conforme à l'invention,
- la figure 2 est une section selon la ligne AA de la figure 1.The invention will be better understood with the aid of the following description of an exemplary embodiment relating to a machine for winding under very high tension a strip on a tubular pipe fixed in position, with reference to the accompanying drawings in which :
FIG. 1 is a schematic side view of the strip winding machine according to the invention,
- Figure 2 is a section along line AA of Figure 1.
En se reportant à l'ensemble des figures 1 et 2, la réference 1 désigne une canalisation fixe en position sur laquelle la machine de l'invention 2 enroule en hélice et sous très forte tension un feuillard métallique 3. Une jante spirale 4 terminée à son extrémité aval par un bec de forme 5 peut tourner, à la manière des dispositifs dits "centerless", autour du corps cylindrique 1. Cette jante est centré par des galets de roulement 6 réglés au diamètre du tube 1 à renforcer et inclinés conformément au pas de l'enroulement à efeffectuer. Referring to all of FIGS. 1 and 2, the reference 1 designates a fixed pipe in position on which the machine of the invention 2 coils in a helix and under very high tension a metal strip 3. A spiral rim 4 finished at its downstream end by a beak of shape 5 can rotate, in the manner of so-called "centerless" devices, around the cylindrical body 1. This rim is centered by rollers 6 adjusted to the diameter of the tube 1 to be reinforced and inclined in accordance with the no winding to be performed.
La bande 3 non encore enroulée est stockee sur une cage à galets libres 7 fixés sur des flasques (8, 9) solidaires de la jante 4. Comme on le voit en particulier sur la figure 2, la spire interieure de la bande 3 passe tout d'abord dans une pince de friction classique 10 à ressort tare 11 et plaque de serrage 12, située à l'ex trémité amont de la jante 4, ce qui permet de lui donner une faible tension d'entrée t sur la jante 4. La bande 3 s'enroule alors sur la jante 4 en patinant sur celle-ci, puis, après avoir passé le bec de forme 5, sur le corps 1. Pour ceci, on fait tourner, dans le sens de la fleche (fig. 2), la jante 4 autour du cylindre 1. The strip 3 not yet wound is stored on a cage with free rollers 7 fixed on flanges (8, 9) integral with the rim 4. As can be seen in particular in FIG. 2, the inner turn of the strip 3 passes completely first in a conventional friction clamp 10 with tare spring 11 and clamping plate 12, located at the upstream end of the rim 4, which allows it to be given a low input voltage t on the rim 4. The strip 3 is then wound on the rim 4 while skating on it, then, after having passed the beak of shape 5, on the body 1. For this, we rotate, in the direction of the arrow (fig. 2), the rim 4 around the cylinder 1.
Si l'on désigne alors par f le coefficient de frottement de la bande 3 sur la jante 4 et par d l'angle d'enroulement de ladite bande, ici voisin de 360 , la tension T obtenue grâce au dispositif de l'invention a pour valeur : T = t . e , en supposant que le patinage de la bande 3 sur la jante 4 s'effectue à la limite d'adhérence. If we then denote by f the coefficient of friction of the strip 3 on the rim 4 and by d the winding angle of said strip, here close to 360, the tension T obtained thanks to the device of the invention a for value: T = t. e, assuming that the strip 3 slips on the rim 4 takes place at the adhesion limit.
L'angle d'enroulement d pouvant hêtre augmenté à volonté en multipliant le nombre de tours de la spirale 4 et la tension d'entree t etant re- glable, on voit que l'on obtient, par le dispositif de l'invention, une tension T de la bande à enrouler d'une intensité aussi élevée que souhaitée et d'une valeur réglable avec précision.The winding angle d can be increased at will by multiplying the number of turns of the spiral 4 and the input voltage t being adjustable, we see that we obtain, by the device of the invention, a tension T of the strip to be wound of an intensity as high as desired and of a value adjustable with precision.
Comme on le voit sur la figure 1, le moteur d'entraînement 13 est fixé sur un chassies 14 portant quatre galets de centrage 15 orientés longitudinalement et reprenant le couple de basculement dû à la tension d'enroulement. La jante 4 tourne autour du châssis 14 à l'aide de roulements à billes 16. Elle est entraînée à l'aide d'un pignon à vis 17, en prise directe sur le moteur 13 et attaquant transversalement une roue dentée 18 solidaire de ladite jante 4. L'ensemble constitué par la vis 17 et la roue dentée 18 forme un dispositif antidévireur permettant, en s'opposant au retour-arrière, de maintenir la tension de l'enroulement déjà effectué.En outre, montée rotative sur la jante 4 à l'aide de roulements à billes (19, 20) se trouve une couronne auxiliaire 21 de diamètre extérieur très légèrement supérieur au diamètre extérieur de la cage à galets 7. Cette couronne auxiliaire permet le stockage de la bande de réserve 22 destinée à continuer la bande 3 en fin d'enroulement de sa bobine de stockage. Cette couronne 21 peut être entraînée à l'aide d'un pignon 23 du moteur 13 et d'une roue dentée 24 en sens inverse du sens de rotation de la jante 4, au moment de la constitution de la bobine de réserve 22. Pour ceci, le pignon 23 est relié au moteur 13 par un inverseur classique contenu dans le boîtier 25 associé audit moteur.Pour placer la bobine 22 sur la cage à galets 7, de manière à continuer l'opération d'enroulement, on fait glisser ladite bobine par translation sur les galets 7, après avoir effectué le raboutage de son extrémité intérieure sur l'extre- mite extérieure de la bande 3, - la machine étant arrêtée. As can be seen in FIG. 1, the drive motor 13 is fixed to a casing 14 carrying four centering rollers 15 oriented longitudinally and taking up the tilting torque due to the winding tension. The rim 4 rotates around the chassis 14 by means of ball bearings 16. It is driven by means of a screw pinion 17, in direct engagement with the motor 13 and attacking transversely a toothed wheel 18 integral with said rim 4. The assembly constituted by the screw 17 and the toothed wheel 18 forms a backstop device making it possible, by opposing the reverse, to maintain the tension of the winding already carried out. In addition, rotatably mounted on the rim 4 using ball bearings (19, 20) is an auxiliary ring 21 with an outside diameter very slightly greater than the outside diameter of the roller cage 7. This auxiliary ring allows the storage of the reserve strip 22 intended for continue strip 3 at the end of winding of its storage reel. This ring 21 can be driven using a pinion 23 of the motor 13 and a toothed wheel 24 in the opposite direction to the direction of rotation of the rim 4, when the reserve coil 22 is formed. this, the pinion 23 is connected to the motor 13 by a conventional inverter contained in the housing 25 associated with said motor. To place the coil 22 on the roller cage 7, so as to continue the winding operation, said slide is made to slide. reel by translation on the rollers 7, after having spliced its inner end on the outer end of the strip 3, - the machine being stopped.
Dans le cas où l'on veut effectuer simultanement deux enroulements superposés et de pas contraire, comme c'est souvent le cas, il suffit de dédoubler la machine en supprimant les galets 15 et en réalisant le symétrique de l'ensemble par rapport au plan transversal passant par la direction BB de la figure 1. Dans ce cas, on aura évidemment avantage à n'utiliser qu'un seul moteur 13 et à munir en conséquence le boîtier 25 de quatre pignons d'attaque au lieu de deux. In the case where one wishes to carry out simultaneously two superimposed windings and of no opposite, as is often the case, it suffices to split the machine by removing the rollers 15 and making the assembly symmetrical with respect to the plane transverse passing through the direction BB of FIG. 1. In this case, it will obviously be advantageous to use only one motor 13 and to consequently provide the housing 25 with four drive pinions instead of two.
L'invention s'applique plus particulièrement à la fabrication de réservoirs et de canalisations destinés à contenir ou vé- hiculer des liquides sous très haute pression. The invention applies more particularly to the manufacture of reservoirs and pipes intended to contain or convey liquids under very high pressure.
