Description

Lorsque des produits souples allongés, comme par exemple des tubes en matière plastique, des câbles ou des profilés souples sont enroulés en torches il est nécessaire de lier chaque torche au moyen d'un lien qui est disposé selon une boucle autour de la section de l'anneau formé par la torche, et cela à plusieurs endroits répartis sur tout le pourtour de cet anneau. On connaît des machines qui comportent deux bras articulés et un dispositif de liage situé entre les bras articulés. Ces machines font parcourir au lien le chemin en forme de boucle qu'il doit parcourir pour entourer la section de l'anneau et lient ensuite les deux extrémités de cette boucle dans une position serrée autour de la torche par exemple par une opération de soudage si le lien est une bande de matière plastique. (Voir EP-0 099 606)When flexible elongated products, such as plastic tubes, cables or flexible profiles are wound in torches it is necessary to link each torch by means of a link which is arranged in a loop around the section of the 'ring formed by the torch, and this in several places distributed around the periphery of this ring. Machines are known which comprise two articulated arms and a binding device located between the articulated arms. These machines make the link traverse the path in the form of a loop which it must traverse to surround the section of the ring and then link the two ends of this loop in a tight position around the torch for example by a welding operation if the link is a strip of plastic. (See EP-0 099 606)

Toutefois, jusqu'à maintenant, l'opération de liage des torches formées sur des enrouleurs automatiques comportant deux tambours de support des torches montés sur un barillet et basculant alternativement entre une position d'enroulement et une position de déchargement n'avait pas encore pu être automatisée complètement dans des conditions permettant d'adapter facilement l'installation au liage de torches dont les dimensions de la section de torches sont différentes.However, until now, the operation of tying the torches formed on automatic reels comprising two drums for supporting the torches mounted on a barrel and rocking alternately between a winding position and an unloading position had not yet been able be fully automated under conditions allowing the installation to be easily adapted to the binding of torches with different dimensions of the torch section.

Le but de la présente invention est de combler cette lacune.The object of the present invention is to fill this gap.

Dans ce but, la présente invention a pour objet une installation de formation de torches comportant, d'une part, un enrouleur équipé de tambours et présentant une position d'arrêt dans laquelle un des tambours est dans une position de liage d'une torche enroulée sur ce tambour, chaque tambour comprenant un assemblage de secteurs répartis à distance les uns des autres autour de l'axe du tambour, et chaque secteur comportant un élément de fût, un premier élément de flasque situé à une extrémité du fût et un second élément de flasque, et, d'autre part, une lieuse munie de bras de guidage d'un lien, agencée de manière à déterminer un point de liage et placée à proximité de l'enrouleur, cette lieuse étant mobile en direction de l'axe du tambour situé en position de liage, les bras étant agencés de manière à s'engager entre deux secteurs du tambour arrêté en position de liage, puis à se refermer autour de la torche. Une telle installation est connue de EP-A 99 606. L'installation selon l'invention est caractérisée en ce que les seconds éléments de flasques des tambours sont mobiles en translation le long des éléments de fût, de manière à permettre un ajustement de la largeur axiale des torches, et en ce que la lieuse est agencée de manière que le point de liage se trouve sensiblement sur une ligne droite définie comme l'intersection d'un plan formant une face frontale de la torche et d'un plan contenant l'axe du tambour et soit mobile le long de cette droite.To this end, the present invention relates to a torch forming installation comprising, on the one hand, a reel equipped with drums and having a stop position in which one of the drums is in a position for tying a torch wound on this drum, each drum comprising an assembly of sectors distributed at a distance from each other around the axis of the drum, and each sector comprising a barrel element, a first flange element located at one end of the barrel and a second flange element, and, on the other hand, a binder provided with a link guiding arm, arranged so as to determine a binding point and placed near the reel, this binder being movable towards the axis of the drum situated in the binding position, the arms being arranged so as to engage between two sectors of the drum stopped in the binding position, then to close around the torch. Such an installation is known from EP-A 99 606. The installation according to the invention is characterized in that the second flange elements of the drums are movable in translation along the barrel elements, so as to allow adjustment of the axial width of the torches, and in that the binder is arranged so that the tying point lies substantially on a straight line defined as the intersection of a plane forming a front face of the torch and a plane containing l axis of the drum and be movable along this straight line.

On va décrire maintenant, à titre d'exemple, et en se référant au dessin annexé une forme d'exécution de l'installation selon l'invention.

We will now describe, by way of example, and with reference to the accompanying drawing, an embodiment of the installation according to the invention.
  • Fig. 1 is an elevational view, schematic and on a small scale, of the entire installation,
  • the. fig. 2 is a plan view also on a small scale of the installation of FIG. 1,
  • fig. 3 and 4 are views respectively in partially cut plan and in perspective, partial and on a larger scale showing a detail of the binder shown in FIGS. 1 and 2,
  • fig. 5, 6 and 7 are schematic top plan views on a larger scale than that of FIGS. 1 and 2 showing the relative positions of the reel and the binder under three different operating conditions of the installation, and

L'installation qui est représentée aux fig. 1 et 2 est destinée à former automatiquement des torches à partir d'un produit souple 1 qui provient d'une ligne de fabrication dont il n'est pas nécessaire de décrire les détails ici. Ce produit souple est guidé par un dispositif de trancannage 2 qu'il n'est pas non plus nécessaire de décrire en détail et au moment où une torche est terminée, il se trouve enroulé sur un tambour 3 qui se trouve en position de déchargement. Ce tambour est monté sur un barillet 4 et fait pendant à un autre tambour 5 qui lui se trouve alors en position d'enroulement. On comprend que, par un moyen non décrit ici, le produit souple 1, par exemple un tuyau en matière plastique, va être sectionné sur le tambour 5, l'extrémité du nouveau brin étant alors fixée au tambour 5 de sorte que l'enroulement d'une nouvellé torche commence sur ce tambour. Le tambour 3 doit alors être arrêté et la torche terminée 6 doit être liée, ceci au moyen d'une machine désignée de façon générale par 7 et qui se trouve au voisinage du tambour en position de déchargement. Cette machine 7 comporte de façon générale un socle 8 fixe à l'intérieur duquel est logé un tambour 9 supportant le lien qui servira à lier la torche 6. Sur ce socle est monté la lieuse proprement dite qui comporte un support 10 des bras articulés 11 et 12 ainsi qu'un dispositif de liage 13. D'autre part, pour comprendre le fonctionnement de la machine et le déroulement du procédé, il faut considérer que chacun des deux tambours 3 et 5 de l'enrouleur, dont le socle 14 supporte rotativement le barillet 4 est constitué d'une série de secteurs 15 comportant chacun un élément de flasque pivotant 16 et un élément de flasque 17 qui est mobile axialement sur l'élément de fût 18 correspondant au secteur 15. Les secteurs de tambour 15 sont portés par une étoile rotative 19 et sont ajustables radialement sur cette pièce, ce qui permet de régler à volonté le diamètre intérieur de la torche. D'autre part, la possibilité de déplacement des secteurs 17 parallèlement à eux- mêmes le long du fût permet de régler à volonté la largeur de la torche que l'on désire réaliser, alors que la possibilité de faire pivoter les éléments de flasque 16 sur l'extrémité du secteur de fût permet d'ouvrir le tambour pour assurer le déchargement de la torche.The installation which is shown in fig. 1 and 2 is intended to automatically form torches from a flexible product 1 which comes from a production line, the details of which need not be described here. This flexible product is guided by a slicing device 2 which is also not necessary to describe in detail and when a torch is finished, it is wound on a drum 3 which is in the unloading position. This drum is mounted on a barrel 4 and is pendant to another drum 5 which is then in its winding position. It is understood that, by a means not described here, the flexible product 1, for example a plastic pipe, will be cut on the drum 5, the end of the new strand then being fixed to the drum 5 so that the winding a new torch begins on this drum. The drum 3 must then be stopped and the finished torch 6 must be linked, this by means of a machine generally designated by 7 and which is located in the vicinity of the drum in the unloading position. This machine 7 generally comprises a fixed base 8 inside which is housed a drum 9 supporting the link which will serve to link the torch 6. On this base is mounted the binder itself which comprises a support 10 of the articulated arms 11 and 12 as well as a binding device 13. On the other hand, to understand the operation of the machine and the process, it must be considered that each of the two drums 3 and 5 of the reel, whose base 14 supports in rotation the barrel 4 is made up of a series of sectors 15 each comprising a pivoting flange element 16 and a flange element 17 which is axially movable on the barrel element 18 corresponding to the sector 15. The drum sectors 15 are carried by a rotary star 19 and are radially adjustable on this part, which allows to adjust at will the inside diameter of the torch. On the other hand, the possibility of displacement of the sectors 17 parallel to themselves along the barrel makes it possible to adjust at will the width of the torch that one wishes to produce, while the possibility of rotating the flange elements 16 on the end of the barrel sector opens the drum to ensure the discharge of the torch.

Selon la fig. 1, le support 10 des bras pivotants 11 et 12 est monté dans une coulisse sur le socle 8, de sorte que ce support peut être déplacé radialement, c.à.d. dans une direction qui est située dans un plan horizontal à la hauteur de l'axe du tambour 3 en position de déchargement. Dans la position de retrait représenté à la fig. 1, le support 10 est placé de telle façon que les bras 11 et 12 se trouvent entièrement à l'extérieur des flasques 16 et 17. En revanche, une fois que le tambour 3 situé en position de déchargement a été arrêté dans une orientation telle que l'espace entre deux secteurs 15 se trouve dans le plan horizontal au niveau de l'axe, on peut, en déplaçant le support 10 sur le socle 8 amener les bras pivotant 11 et 12 à s'engager entre deux secteurs 15 jusqu'à une distance de l'axe qui est inférieure au rayon sur lequel s'étend l'élément de fût 18. C'est ce que représente la fig. 2. On comprend donc qu'il est possible que lors de ce mouvement les bras pivotant 11 et 12 embrassent la torche terminée et que d'autre part un lien entraîné par des galets et guidé le long de la face interne des deux bras 11 et 12 parcourt un chemin tel qu'il entoure complètement la section de la torche.According to fig. 1, the support 10 of the pivoting arms 11 and 12 is mounted in a slide on the base 8, so that this support can be moved radially, i.e. in a direction which is situated in a horizontal plane at the height of the axis of the drum 3 in the unloading position. In the withdrawal position shown in fig. 1, the support 10 is placed so that the arms 11 and 12 are entirely outside the flanges 16 and 17. On the other hand, once the drum 3 located in the unloading position has been stopped in such an orientation that the space between two sectors 15 is in the horizontal plane at the level of the axis, it is possible, by moving the support 10 on the base 8, to bring the pivoting arms 11 and 12 to engage between two sectors 15 until at a distance from the axis which is less than the radius over which the barrel element 18 extends. This is what FIG. 2. It is therefore understood that it is possible that during this movement the pivoting arms 11 and 12 embrace the completed torch and that, on the other hand, a link driven by rollers and guided along the internal face of the two arms 11 and 12 travels along a path such that it completely surrounds the section of the torch.

L'agencement qui permet ce déplacement est représenté plus en détail aux fig. 3 et 4. A la fig. 3, on voit tout d'abord une partie de la tête de liage 13. D'autre part, sur une partie proéminente du support 10 on voit les moyens qui sont prévus pour amener un lien 20 à se déplacer le long des bras pivotants et en particulier du bras 12 dont l'embase est visible à cette fig. 3. Le lien 20 est conduit de façon à passer entre deux galet 21 et 22. Le galet 21 est monté selon un axe fixe sur le support 10. Il est entraîné par un moteur et entraîne par deux engrenages le galet 22 qui est monté sur un levier de support 23 pivotant en 24 sur le support 10 et sollicité par un ressort 25 réglable au moyen d'une vis 26 sur une butée 27. Le lien 20 est conduit de façon à passer entre les deux galets 21 et 22, puis autour du galet 22 et dirigé ensuite le long de la façe frontale de la tête de liage 13. Après avoir passé devant l'élément 29 qui joue un rôle particulier comme on l'expliquera plus loin, le lien 20 pénètre dans une coulisse de guidage 28. Cette dernière a la forme visible à la fig. 4. Elle est constituée d'une enveloppe souple présentant une fente à sa partie médiane. Cette coulisse recouvre l'extrémité gauche de la tête de liage 13 à la fig. 3, ainsi que les faces internes des deux bras pivotants 11 et 12. On comprend que l'extrémité du lien étant poussée par les galets 21 et 22 dans la coulisse 28, elle va suivre progressivement toute la longueur de la face interne du bras 11 puis celle du bras 12 et décrire ainsi une boucle fermée, l'extrémité arrivant finalement devant le moyen de blocage 29. A cet endroit cette extrémité peut être bloquée, par exemple par un élément magnétique ou par tout autre moyen de fixation temporaire. Si ensuite on entraîne les galets 21 et 22 dans le sens inverse à celui de l'enroulement du lien autour de la torche, l'extrémité du lien restant fixée à l'élément 29, alors le lien est sollicité de façon à se dégager de la coulisse 28 en soulevant les deux languettes opposées de cette coulisse. C'est ce qui permet le serrage de la torche et finalement la fixation du lien.The arrangement which allows this movement is shown in more detail in FIGS. 3 and 4. In fig. 3, we see first of all a part of the binding head 13. On the other hand, on a prominent part of the support 10 we see the means which are provided to cause a link 20 to move along the pivoting arms and in particular of the arm 12 whose base is visible in this fig. 3. The link 20 is driven so as to pass between two rollers 21 and 22. The roller 21 is mounted along a fixed axis on the support 10. It is driven by a motor and drives the roller 22 which is mounted on two gears a support lever 23 pivoting at 24 on the support 10 and biased by a spring 25 adjustable by means of a screw 26 on a stop 27. The link 20 is conducted so as to pass between the two rollers 21 and 22, then around of the roller 22 and then directed along the front face of the binding head 13. After passing in front of the element 29 which plays a particular role as will be explained below, the link 20 enters a guide slide 28 The latter has the form visible in FIG. 4. It consists of a flexible envelope having a slit in its middle part. This slide covers the left end of the binding head 13 in FIG. 3, as well as the internal faces of the two pivoting arms 11 and 12. It is understood that the end of the link being pushed by the rollers 21 and 22 in the slide 28, it will progressively follow the entire length of the internal face of the arm 11 then that of the arm 12 and thus describe a closed loop, the end finally arriving in front of the blocking means 29. At this point this end can be blocked, for example by a magnetic element or by any other temporary fixing means. If then the rollers 21 and 22 are driven in the opposite direction to that of the winding of the link around the torch, the end of the link remaining fixed to the element 29, then the link is stressed so as to be released from the slide 28 by lifting the two opposite tabs of this slide. This is what allows the torch to be tightened and ultimately the link to be fixed.

Ces deux dernières opérations sont décrites maintenant en se référant aux fig. 5, 6 et 7. A la fig. 5 on voit la lieuse 7 avec son support 10, les deux galets 21 et 22 et les deux bras pivotant 12 et 11 en position d'engagement sur un secteur 15 monté sur l'étoile 19 à une distance de l'axe du tambour qui correspond au diamètre maximum de la torche. De plus, le flasque mobile en translation 17 se trouve dans la position la plus écartée possible du flasque pivotant 16 et cette position permet de réaliser la torche susceptible de contenir la plus grande longueur de tube 1 possible. Lorsque le lien a été amené dans la position représentée à cette figure, le moteur d'entrai- nement des galets 21 et 22 est donc arrêté puis réenclenché dans le sens inverse après que le segment 29 a été commandé de façon à fixer l'extrémité du lien. En même temps, la tête de liage 13, qui détermine le point de liage, est déplacée par rapport au socle 8 (non représenté à la fig. 5) et au support 10 de façon que le point de liage se trouve sur la surface cylindrique externe de la torche au voisinage immédiat de la paroi frontale limitée par le flasque 16. On comprend que ceci permet de serrer le lien autour de la torche et d'exécuter automatiquement au moyen de la tête 13, la fixation des deux extrémités du lien et le coupage du lien au droit de la boucle ainsi formée. Cette opération étant effectuée le support 10 et la tête 13 peuvent être ramenés en arrière de façon à permettre la rotation du tambour d'un angle correspondant à la largeur angulaire des secteurs 15, de sorte qu'un nouvel espace situé entre deux secteurs se trouve dans le plan horizontal en regard de la lieuse. L'opération de liage peut alors recommencer et être répétée de manière à placer un lien dans chacun des espaces entre deux secteurs 15. On peut aussi se contenter de lier la torche au moyen d'une ou deux ou trois boucles 31 (fig. 8) le nombre maximum correspondant au nombre d'intervalles entres les secteurs du tambour.These last two operations are now described with reference to FIGS. 5, 6 and 7. In fig. 5 we see the binder 7 with its support 10, the two rollers 21 and 22 and the two pivoting arms 12 and 11 in the engagement position on a sector 15 mounted on the star 19 at a distance from the axis of the drum which corresponds to the maximum diameter of the torch. In addition, the flange movable in translation 17 is in the position as far apart as possible from the pivoting flange 16 and this position makes it possible to produce the torch capable of containing the greatest length of tube 1 possible. When the link has been brought to the position shown in this figure, the drive motor for the rollers 21 and 22 is therefore stopped and then reset in the opposite direction after the segment 29 has been controlled so as to fix the end of the link. At the same time, the tying head 13, which determines the tying point, is moved relative to the base 8 (not shown in fig. 5) and to the support 10 so that the tying point is on the cylindrical surface external of the torch in the immediate vicinity of the front wall limited by the flange 16. It is understood that this makes it possible to tighten the link around the torch and to execute automatically by means of the head 13, the fixing of the two ends of the link and cutting the link to the right of the loop thus formed. This operation being carried out the support 10 and the head 13 can be brought back so as to allow the rotation of the drum by an angle corresponding to the angular width of the sectors 15, so that a new space located between two sectors is in the horizontal plane opposite the binder. The binding operation can then start again and be repeated so as to place a link in each of the spaces between two sectors 15. It can also be content to tie the torch by means of one or two or three loops 31 (fig. 8 ) the maximum number corresponding to the number of intervals between the sectors of the drum.

Si maintenant la torche que l'on désire fabriquer a le même diamètre qu'avec la disposition de la fig. 5, mais une largeur axiale réduite, les opérations à effectuer découlent de ce que l'on voit à la fig. 6. Le flasque coulissant 17 a été déplacé par rapport à l'élément de fût 18 du secteur 15. La tête 13 et l'élément 29 peuvent encore être déplacés radialement en direction de l'axe jusqu'au moment où la tête de liage 13 se trouve appliquée contre la face cylindrique externe de la torche à proximité immédiate flasque 16. Il est donc possible de lier une torche de largeur et de diamètre minimale après un réajustage du point de liage qui peut être programmé.If now the torch which one wishes to manufacture has the same diameter as with the arrangement of FIG. 5, but a reduced axial width, the operations to be carried out result from what is seen in FIG. 6. The sliding flange 17 has been moved relative to the barrel element 18 of the sector 15. The head 13 and the element 29 can still be moved radially in the direction of the axis until the tying head 13 is applied against the external cylindrical face of the torch in the immediate vicinity of the flange 16. It is therefore possible to link a torch of minimum width and diameter after a readjustment of the binding point which can be programmed.

Finalement la fig. 7 montre les positions relatives du support 10 de la tête 13 et de l'élément 29 par rapport à l'axe du tambour dans le cas où, les secteurs 15 sont placés à une distance de l'axe qui est minimale. On se rend compte ainsi que l'ensemble des réglages nécessaires pour adapter la machine à une torche de section quelconque se réduit à des réglages effectués selon une même ligne droite définie comme l'intersection de deux plans qui sont d'une part le plan perpendiculaire à l'axe du tambour et définissant la face frontale de la torche voisine des éléments de flasque 16, et d'autre part le plan horizontal passant par l'axe du tambour. Tous les réglages peuvent être effectués en déplaçant soit le support des bras pivotants soit la tête de liage dans cette direction.Finally fig. 7 shows the relative positions of the support 10 of the head 13 and of the element 29 with respect to the axis of the drum in the case where the sectors 15 are placed at a distance from the axis which is minimal. We thus realize that all of the adjustments necessary to adapt the machine to a torch of any section is reduced to adjustments made along the same straight line defined as the intersection of two planes which are on the one hand the perpendicular plane to the axis of the drum and defining the front face of the torch close to the flange elements 16, and on the other hand the horizontal plane passing through the axis of the drum. All adjustments can be made by moving either the swivel arm support or the tying head in this direction.

On notera encore que, pour assurer automatiquement le serrage du lien sur la torche quelle que soit sa section, une seule opération est nécessaire: avant de commencer l'opération de liage proprement dite sur une torche ou sur une série de torches de même section, on commence par mesurer le périmètre de sa section. Pour cela, le lien 20 (fig. 3) est avancé dans la coulisse 28 de façon à parcourir la face interne de l'ensemble des deux bras 11 et 12, et durant cette opération le nombre de tours du galet 21 est compté dans un dispositif électronique adéquat. Lorsque l'extrémité du lien est arrivée devant l'élément de fixation 29, le moteur est arrêté puis réenclenché dans le sens inverse une fois que l'extrémité du lien a été fixée à l'élément 29, le nombre de tours effectués dans le sens inverse par le moteur 21 étant également strictement compté. Ainsi il est possible de mémoriser les deux longueurs de déplacement du lien 20 permettant d'une part de fermer la boucle sur elle-même et d'autre part de diminuer sa longueur de manière qu'elle soit tendue sur la section de la torche. Ces deux valeurs étant mises en mémoire, l'ensemble de l'opération de liage peut s'effectuer automatiquement.It will also be noted that, to automatically ensure the tightening of the link on the torch whatever its section, a single operation is necessary: before starting the actual binding operation on a torch or on a series of torches of the same section, we start by measuring the perimeter of its section. For this, the link 20 (fig. 3) is advanced in the slide 28 so as to traverse the internal face of the assembly of the two arms 11 and 12, and during this operation the number of turns of the roller 21 is counted in a adequate electronic device. When the end of the link has arrived in front of the fixing element 29, the engine is stopped and then reset in the opposite direction once the end of the link has been fixed to the element 29, the number of revolutions made in the reverse by motor 21 also being strictly counted. Thus it is possible to memorize the two displacement lengths of the link 20 allowing on the one hand to close the loop on itself and on the other hand to reduce its length so that it is stretched over the section of the torch. These two values being stored, the entire binding operation can be performed automatically.
