Description

La présente invention se rapporte à un dispositif d'enroulage de bobine souple.The present invention relates to a flexible reel winding device.

Il est connu de réaliser des dispositifs d'enroulage mono-axe comprenant un support, par exemple un touret, un tambour ou une bobine, sur lequel est enroulé un produit, par exemple un fil, un câble, un tuyau ou une bandelette. Dans les dispositifs d'enroulage connus, l'enroulage du produit sur le support s'effectue grâce à un système de trancannage, permettant un enroulage du produit de manière ordonnée. Le système de trancannage se translate selon l'axe du support dans un sens puis dans l'autre. Le support peut comporter à chaque extrémité des rebords appelés joues. Dès que le système de trancannage s'approche d'une joue, celui-ci repart dans le sens inverse jusqu'à s'approcher de l'autre joue et inverser de nouveau son sens de translation. Ainsi, l'enroulage du produit sur le support est réalisé spire après spire puis couche après couche, une nouvelle couche de produit venant couvrir la couche précédente à chaque changement de sens du système de trancannage.It is known to make single-axis reeling devices comprising a support, for example a reel, a drum or a reel, on which is rolled a product, for example a wire, a cable, a pipe or a strip. In known winding devices, the winding of the product on the support is carried out by means of a cutting system, allowing a winding of the product in an orderly manner. The cutting system is translated along the axis of the support in one direction and then in the other. The support may have at each end flanges called cheeks. As soon as the slicing system approaches one cheek, it starts in the opposite direction until it approaches the other cheek and reverse its direction of translation again. Thus, the winding of the product on the support is made turn after turn then layer after layer, a new product layer covering the previous layer at each change of direction of the cutting system.

Il est également connu d'effectuer l'enroulage du produit sur le support par translation du support lui-même le long de son axe, dans un mouvement de va et vient.It is also known to perform the winding of the product on the support by translation of the support itself along its axis, in a movement back and forth.

Ces dispositifs d'enroulage connus donnent généralement satisfaction dans la mesure où ils permettent un enroulage uniforme du produit.These known winding devices are generally satisfactory in that they allow uniform winding of the product.

Cependant, ces dispositifs d'enroulage n'offrent qu'un enroulage discontinu du produit. De plus, il est nécessaire à l'opérateur d'intervenir pour couper le produit et terminer ainsi la bobine, puis de retirer cette bobine et d'amorcer l'enroulage d'une nouvelle bobine. C'est une opération qui monopolise un opérateur et qui prend du temps au détriment de la productivité.However, these winding devices offer only a discontinuous winding of the product. In addition, it is necessary for the operator to intervene to cut the product and thus terminate the coil, then remove the coil and initiate the winding of a new coil. It is an operation that monopolizes an operator and takes time at the expense of productivity.

Aussi, la présente invention a pour but de résoudre tout ou partie des inconvénients mentionnés ci-dessus.Also, the present invention aims to solve all or part of the disadvantages mentioned above.

Un but de l'invention est de proposer un dispositif d'enroulage de bobine de produit souple offrant le remplacement automatique d'une bobine terminée par un support vierge sur lequel peut être enroulée une nouvelle bobine.An object of the invention is to provide a flexible product coil winding device offering the automatic replacement of a coil terminated by a blank support on which can be wound a new coil.

Un autre but de l'invention est de proposer un dispositif d'enroulage de bobine de produit souple offrant une découpe automatisée d'une bobine terminée et un amorçage automatisé de l'enroulage d'une seconde bobine.Another object of the invention is to provide a flexible product reel winding device providing automated cutting of a finished reel and automated initiation of the reeling of a second reel.

Un autre but de l'invention est de proposer un dispositif d'enroulage de bobine de produit souple offrant un enroulage en continu du produit à enrouler.Another object of the invention is to provide a device for winding a flexible product reel providing a continuous winding of the product to be wound.

A cet effet, la présente invention a pour objet un dispositif d'enroulage d'un produit sur une barre d'enroulage, comportant un système de trancannage muni de moyens de mise en translation dans un sens puis dans l'autre selon un axe parallèle à la barre d'enroulage, et des moyens d'amenée du produit sur la barre d'enroulage, la barre d'enroulage étant munie de moyens de mise en rotation autour de son axe de rotation afin de permettre l'enroulage du produit sur la barre d'enroulage, caractérisé en ce que le dispositif d'enroulage comporte au moins une seconde barre d'enroulage parallèle à la barre d'enroulage et des moyens de changement de position des barres d'enroulage permettant de positionner la seconde barre d'enroulage à la place de la première barre d'enroulage lorsqu'une longueur prédéterminée de produit a été enroulée sur la première barre d'enroulage, afin de permettre l'amorçage et l'enroulage automatique d'une nouvelle bobine.For this purpose, the subject of the present invention is a device for winding a product on a winding bar, comprising a slicing system provided with translation means in one direction and then in the other along a parallel axis. at the winding bar, and means for feeding the product onto the winding bar, the winding bar being provided with means for rotating around its axis of rotation in order to allow the winding of the product on the winding bar, characterized in that the winding device comprises at least one second winding bar parallel to the winding bar and means for changing the position of the winding bars for positioning the second winding bar. winding in place of the first winding bar when a predetermined length of product has been wound on the first winding bar, to allow automatic priming and winding of a new spool.

La figure 1 représente un dispositif d'enroulage 1 de bobine de produit souple. Le dispositif d'enroulage 1 comprend un système de trancannage 2. Le système de trancannage 2 comporte des moyens d'amenée d'un produit 7 sur une barre d'enroulage 3. Dans le mode de réalisation décrit, ces moyens d'amenée du produit 7 comportent un bras de trancannage 4 dont l'extrémité est pourvue d'un galet rotatif 5, masqué par le bras de trancannage 4 sur les différentes figures, et d'un galet rotatif 6. Les galets rotatifs 5,6 supportent le produit 7 acheminé en continu sur la barre d'enroulage 3. En fonctionnement, le galet rotatif 6 permet de mettre en contact le produit 7 avec la barre d'enroulage 3. Le produit 7 est en effet pris en sandwich entre le galet rotatif 6 et la barre d'enroulage 3.The figure 1 represents a winding device 1 of flexible product coil. The winding device 1 comprises a slicing system 2. The slicing system 2 comprises means for feeding a product 7 onto a winding bar 3. In the embodiment described, these means of feeding the product 7 comprise a cutting arm 4 whose end is provided with a rotary roller 5, masked by the cutting arm 4 in the different figures, and a rotary roller 6. The rotary rollers 5,6 support the product 7 In operation, the rotary roller 6 makes it possible to put the product 7 into contact with the winding bar 3. The product 7 is in fact sandwiched between the rotary roller 6 and the winding bar 3.

La barre d'enroulage 3 comporte des moyens de mise en rotation autour de son axe de rotation, non représentés, afin de permettre l'enroulage du produit autour de la barre d'enroulage 3.

A coil 8 of product 7 is formed as the product 7 is wound up.

Le bras de trancannage 4 comporte une liaison pivot permettant une rotation du bras de trancannage 4 par rapport à un axe parallèle à l'axe d'enroulage. Cela permet de maintenir le galet rotatif 6 appuyé contre la bobine 8 au fur et à mesure que le produit 7 est enroulé sur la barre d'enroulage 3.The cutting arm 4 comprises a pivot connection allowing a rotation of the cutting arm 4 relative to an axis parallel to the winding axis. This keeps the rotary roller 6 pressed against the coil 8 as the product 7 is wound on the winding bar 3.

Le dispositif d'enroulage 1 selon le mode de réalisation décrit de l'invention comporte un plateau 9. Comme cela est représenté sur les figures 1 à 5, le plateau 9 décrit la forme d'un disque. Le plateau 9 est capable de pivoter autour d'un axe de rotation 1, visible notamment sur la figure 5.The winding device 1 according to the described embodiment of the invention comprises a plate 9. As is shown in FIGS. figures 1 at 5 , the plate 9 describes the shape of a disc. The plate 9 is able to pivot about an axis of rotation 1, visible in particular on the figure 5 .

Un des côtés du plateau 9 comporte au moins deux barres d'enroulage 3,10. Les barres d'enroulage 3,10 sont excentrées par rapport à l'axe de rotation I du plateau 9. Les barres d'enroulage 3,10 sont parallèles à l'axe de rotation I du plateau 9.One of the sides of the plate 9 comprises at least two winding bars 3,10. The winding bars 3, 10 are eccentric with respect to the axis of rotation I of the plate 9. The winding bars 3, 10 are parallel to the axis of rotation I of the plate 9.

Le dispositif d'enroulage 1 selon le mode de réalisation décrit comporte également un système de coupe 11 du produit 7 lorsque la longueur désirée de produit 7 enroulé sur une barre d'enroulage 3 ou 10 a été atteinte. Le système de coupe 11 comporte un bras 12 pivotant selon un axe parallèle à l'axe d'enroulage.The winding device 1 according to the described embodiment also comprises a cutting system 11 of the product 7 when the desired length of product 7 wound on a winding bar 3 or 10 has been reached. The cutting system 11 comprises an arm 12 pivoting along an axis parallel to the winding axis.

Le bras 12 comporte une première partie 12a et une seconde partie 12b liées entre elles par une liaison pivot. La première partie 12a et la seconde partie 12b du bras 12 présentent chacune une paroi 13a, 13b en forme d'arc de cercle. L'arc de cercle formé par les parois 13a,13b présente un diamètre égal ou supérieur à celui des barres d'enroulage 3,10. Ainsi, le bras 12 présente une forme de « col de cygne ». Le bras 12 comporte aussi des moyens de mise en rotation relative de la première partie et de la seconde partie, par exemple un vérin 14. L'une des extrémités du bras 12 est pourvue de moyens de coupe, par exemple un ciseau de coupe 15.The arm 12 has a first portion 12a and a second portion 12b interconnected by a pivot connection. The first portion 12a and the second portion 12b of the arm 12 each have a wall 13a, 13b in the shape of a circular arc. The arc formed by the walls 13a, 13b has a diameter equal to or greater than that of the winding bars 3,10. Thus, the arm 12 has a shape of "gooseneck". The arm 12 also comprises relative rotation means for rotating the first portion and the second portion, for example a jack 14. One of the ends of the arm 12 is provided with cutting means, for example a cutting chisel 15 .

Les figures 1 à 4 illustrent différentes étapes du fonctionnement du dispositif d'enroulage 1 selon le mode de réalisation décrit. Dans une première étape de fonctionnement, représentée à la figure 1, le produit 7 est enroulé autour de la barre d'enroulage 3, formant une bobine 8. La barre d'enroulage 10 n'est pas utilisée. Lorsque la longueur de produit 7 désirée est atteinte par la première bobine 8, le plateau 9 pivote, de sorte que la barre d'enroulage 10 occupe la position qu'occupait la barre d'enroulage 3. Ainsi, la barre d'enroulage 10 vient au contact du produit 7 au niveau du galet rotatif 6, comme cela est représenté sur la figure 2. Le bras 12 pivote autour de son axe de rotation, de sorte que la paroi 13a enserre partiellement la barre d'enroulage 10. Le vérin 14 actionne ensuite la rotation de la seconde partie 12b du bras 12 par rapport à la première partie 12a, de sorte que la paroi 13b achève d'enserrer la barre d'enroulage 10, comme cela est montré à la figure 3. Ainsi est amorcé l'enroulage du produit 7 sur la barre d'enroulage 10, le produit 7 adhérant instantanément sur la barre d'enroulage 10. Le ciseau de coupe 15 permet de couper le produit 7 à la longueur désirée. Bien que cela ne soit pas visible sur les différentes figures, cette opération nécessite, dans le mode de réalisation décrit, que le bras de trancannage 4 amenant la bandelette de produit 7 sur la barre d'enroulage 3 soit sensiblement positionné, à la fin de l'enroulage de la bobine 8, dans le même plan, perpendiculaire à l'axe d'enroulage, que le système de coupe 11. Ce positionnement est obtenu grâce au principe de correction dynamique du pas de trancannage, décrit dans le paragraphe suivant. Une fois l'opération de coupe terminée, la seconde partie 12b du bras 12 s'ouvre afin de libérer la barre d'enroulage 10 et le bras 12 pivote afin de retrouver sa position initiale. L'enroulage du produit 7 se poursuit autour de la barre d'enroulage 10, pendant que l'opérateur peut décharger la bobine 8 créée sur la barre d'enroulage 3. Une fois qu'une seconde bobine est enroulée sur la barre d'enroulage 10, l'opération se répète, la barre d'enroulage 3 venant prendre la place de la barre d'enroulage 10. Le dispositif d'enroulage 1 permet ainsi un enroulage continu et offre une découpe du produit 7 et un amorçage automatisés de l'enroulage sur les barres d'enroulage 3,10.The Figures 1 to 4 illustrate different steps of the operation of the winding device 1 according to the embodiment described. In a first step of operation, represented in figure 1 , the product 7 is wound around the winding bar 3, forming a coil 8. The winding bar 10 is not used. When the desired length of product 7 is reached by the first coil 8, the plate 9 pivots, so that the winding bar 10 occupies the position occupied by the winding bar 3. Thus, the winding bar 10 comes into contact with the product 7 at the rotary roller 6, as shown in FIG. figure 2 . The arm 12 pivots about its axis of rotation, so that the wall 13a partially encloses the winding bar 10. The cylinder 14 then actuates the rotation of the second portion 12b of the arm 12 relative to the first portion 12a, of so that the wall 13b completes gripping the winding bar 10, as shown in FIG. figure 3 . Thus is initiated the winding of the product 7 on the winding bar 10, the product 7 adhering instantly on the winding bar 10. The cutting chisel 15 cuts the product 7 to the desired length. Although it is not visible in the various figures, this operation requires, in the embodiment described, that the cutting arm 4 bringing the product strip 7 on the winding bar 3 is substantially positioned at the end of the winding of the coil 8, in the same plane, perpendicular to the winding axis, as the cutting system 11. This positioning is obtained through the principle of dynamic correction of the slicing step, described in the following paragraph. Once the cutting operation is completed, the second portion 12b of the arm 12 opens to release the winding bar 10 and the arm 12 pivots to return to its initial position. The winding of the product 7 continues around the winding bar 10, while the operator can unload the spool 8 created on the winding bar 3. Once a second spool is wound on the winding bar 10, the operation is repeated, the winding bar 3 to take the place of the winding bar 10. The winding device 1 and allows a continuous winding and offers a cutting of the product 7 and an automated boot of winding on the winding bars 3,10.

Dans le dispositif d'enroulage 1 selon le mode de réalisation décrit de l'invention, le système de trancannage 2 est un système de trancannage numérique qui permet de maîtriser le pas de trancannage. Le pas de trancannage correspond à la distance, mesurée selon la direction de l'axe d'enroulage, séparant les centres de deux spires consécutives de produit 7. La correction dynamique du pas de trancannage est nécessaire dans la mesure où le trancannage numérique ne permet pas d'obtenir un fonctionnement identique pour chaque bobine 8, et ce en raison notamment de la compacité de la bobine 8 ou du type de produit 7 enroulé. En effet, au démarrage de chaque bobine 8, le bras de trancannage 4 est situé au même endroit par rapport à la bobine 8 pour chaque tête d'enroulage 16,17,18,19, comme cela est représenté sur la figure 7. En fonctionnement, après quelques couches de produit 7 déposées sur chaque bobine 8, les bras de trancannage 4 sont décalés les uns par rapport aux autres, comme cela est représenté sur la figure 8. Ce phénomène s'accentue au fur et à mesure que les bobines 8 s'enroulent. La correction dynamique du pas de trancannage vise à y remédier, pour faire en sorte que tous les bras de trancannage 4 arrivent au même moment devant le système de coupe 11, visible sur la figure 9. Pour ce faire, le bras de trancannage 4 le plus rapide est pris pour référence. Dans l'exemple illustré à la figure 8, il s'agit du bras de trancannage 4 distant d'une longueur L2 de sa position initiale, à savoir le bras de trancannage 4 de la tête d'enroulage 17. La correction dynamique du pas de trancannage consiste alors, lorsque l'écart entre les bras de trancannage 4 est trop important, à augmenter la vitesse des bras de trancannage 4 en retard par rapport au bras de trancannage 4 de référence. Cela a pour effet d'augmenter le pas de trancannage et de permettre à tous les bras de trancannage 4 de se positionner en même temps à proximité du système de coupe 11. Dans l'exemple illustré à la figure 8, la vitesse des bras de trancannage 4 des têtes d'enroulage 16,18,19 est ainsi augmentée.In the winding device 1 according to the described embodiment of the invention, the cutting system 2 is a digital cutting system that allows to control the step of slicing. The pitch corresponds to the distance, measured in the direction of the winding axis, separating the centers of two consecutive turns of product 7. The dynamic correction of the pitch is necessary because the digital cutting does not allow not to obtain an identical operation for each coil 8, and this due in particular to the compactness of the coil 8 or the type of product 7 wound. Indeed, at the start of each coil 8, the cutting arm 4 is located at the same location with respect to the coil 8 for each winding head 16,17,18,19, as shown in FIG. figure 7 . In operation, after a few layers of product 7 deposited on each coil 8, the cutting arms 4 are offset relative to each other, as shown in FIG. figure 8 . This phenomenon is accentuated as the coils 8 roll up. The dynamic correction of the step is intended to remedy this, to ensure that all the cutting arms 4 arrive at the same time in front of the cutting system 11, visible on the figure 9 . To do this, the fastest 4-handed cutting arm is taken for reference. In the example shown in figure 8 it is the remote arm 4 of a length L 2 of its initial position, namely the cutting arm 4 of the winding head 17. then, when the gap between the cutting arms 4 is too large, the dynamic correction of the non-cutting step is to increase the speed of the cutting arms 4, which is delayed relative to the reference cutting arm 4. This has the effect of increasing the step of slicing and allow all the cutting arms 4 to position themselves at the same time near the cutting system 11. In the example shown in FIG. figure 8 the speed of the cutting arms 4 of the winding heads 16, 18, 19 is thus increased.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit ci-dessus, ce mode de réalisation n'ayant été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par la substitution d'équivalents techniques, sans pour autant sortir du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described above, this embodiment having been given as an example. Modifications are possible, in particular from the point of view of the constitution of the various elements or by the substitution of technical equivalents, without departing from the scope of protection of the invention.

Ainsi, le bras 12 peut comporter une seule partie munie d'une paroi 13 en arc de cercle destinée à enserrer la barre d'enroulage 3 ou 10.Thus, the arm 12 may comprise a single portion provided with a wall 13 in a circular arc for gripping the winding bar 3 or 10.

Ainsi, le dispositif d'enroulage 1 peut comporter plus de deux barres d'enroulage.Thus, the winding device 1 may comprise more than two winding bars.

Il est encore possible que l'invention soit mise en oeuvre dans le cadre d'un trancannage dans lequel le bras de trancannage 4 est fixe et dans lequel ce sont les barres d'enroulage 3, 10 qui sont mobiles en translation le long de l'axe d'enroulage, animées d'un mouvement de va-et-vient permettant l'enroulage du produit 7 sous la forme d'une bobine 8.It is still possible that the invention is implemented in the context of a trancouver in which the cutting arm 4 is fixed and in which it is the winding bars 3, 10 which are movable in translation along the l winding axis, moved back and forth for winding the product 7 in the form of a coil 8.
