Abstract

Each coil builds up on equally spaced, narrow, axially oriented slats (340) arranged around a notional cylinder whose horizontal axis is perpendicular to the direction (X) of extrusion. At one end, the slats are cantilevered on mountings adjustable, to set inner diameter of the coil, along spokes (33) extending radially from a central disk. Radial side-bars (341), axially adjustable along the slats, determine the coil width. This assembly (33,340,341), with a supporting base (31), axle (36) and drive motor (331), can slide on transverse rails (30) into contact with a corresponding inboard disk (32), defining the other side of the coil. This disk, rotating freely on bearings (320) on a fixed central support (300), is then driven by the outboard disk. The traversing feeding head (4) directs newly extruded tube, etc. to form coils on each frame (A,B) alternately. Completed coils are bound by ligatures passed through their open centers by the retractable arms (52) of a binding unit (5), which also cuts the coil at the correct length. Relaxing devices on the slats free them from the coil, whose weight passes to rollers (60,61), raised from the bars. The outboard assembly then withdraws laterally (30), allowing the coil to roll into a railed (63) dispatch area. The supervising controller (7) is opt. integrated with the extrusion line controller.

Description

La présente invention concerne un dispositif de mise en torches d'un élément longiligne, par exemple un tube, obtenu par extrusion d'un matériau synthétique ou par tout autre procédé de production en continu.The present invention relates to a device for flaring a elongated element, for example a tube, obtained by extruding a material synthetic or by any other continuous production process.

Il est connu que certains éléments longilignes obtenus par extrusion en continu sont récoltés après avoir été refroidis, en forme de torche, constituée d'une pluralité de couches successives de spires disposées côte à côte, ce qui évite l'utilisation de bobines de transport ou de stockage. De préférence, le dispositif de confection de la torche est associé à un dispositif apte à disposer une ligature en plusieurs endroits autour des spires assemblées formant la torche, de manière à la maintenir en forme.It is known that certain elongated elements obtained by extrusion continuously are harvested after being cooled, torch-shaped, consisting of a plurality of successive layers of turns arranged side by side side, which avoids the use of transport or storage coils. Of preferably, the device for making the torch is associated with a device suitable for placing a ligature in several places around the turns assemblies forming the torch, so as to keep it in shape.

Vu que l'élément longiligne est obtenu par un procédé d'extrusion en continu, le dispositif de mise en torche doit être conçu de telle manière que lorsqu'une torche est complète et que l'élément longiligne a été coupé, des moyens soient prévus permettant de recevoir l'extrémité coupée pour former une nouvelle torche, sans qu'il soit nécessaire d'arrêter le processus d'extrusion.Since the elongated element is obtained by an extrusion process in continuous, the flaring device must be designed in such a way that when a torch is complete and the elongated element has been cut, means are provided for receiving the cut end to form a new torch, without the need to stop the process extrusion.

Un dispositif de mise en forme est décrit dans le brevet EP-0.426.614. Ce dispositif prévoit deux dispositifs de mise en torche disposés chacun à une extrémité d'un bras pivotant. Lorsqu'une première torche est terminée, le bras pivotant bascule amenant l'autre dispositif de mise en torche en face des moyens d'amenée de l'élément longiligne, alors que l'emballage de la première torche peut être terminé et celle-ci sortie du dispositif durant la confection de la torche suivante.A shaping device is described in patent EP-0,426,614. This device provides two flaring devices arranged each at one end of a pivoting arm. When a first torch is finished, the swivel arm rocks bringing the other torch device opposite the means for supplying the elongated element, while the packaging of the first torch can be finished and it left the device during the making the next torch.

Un tel dispositif est difficilement utilisable lorsque les dimensions de la torche deviennent importantes, soit lorsque l'élément longiligne mis en torche est de très grande longueur, soit lorsque cet élément possède un diamètre important. Dans ces cas, les masses et les volumes à mettre en mouvement lors du pivotement du bras mobile deviennent très importants et les dimensions du dispositif deviennent prohibitives, notamment en hauteur, vu les diamètres des torches.Such a device is difficult to use when the dimensions of the torch becomes important, either when the elongated element put in torch is very long, either when this element has a large diameter. In these cases, the masses and volumes to be used movement during pivoting of the movable arm becomes very important and the dimensions of the device become prohibitive, especially in height, given the torch diameters.

Un premier but de l'invention est de proposer un dispositif de confection de torches d'un élément longiligne muni de moyens permettant d'alimenter un deuxième moyen de mise en torche dès qu'une longueur déterminée de l'élément longiligne a été assemblée sur un premier moyen de mise en torche, ledit dispositif étant d'encombrement limité.A first object of the invention is to propose a device for making torches of a slender element provided with means allowing to supply a second means of flaring as soon as a length of the elongated element has been assembled on a first means of torch, said device being of limited size.

Un deuxième but de l'invention est de proposer un dispositif de mise en torches muni d'un dispositif de trancanage automatique de la première torche puis des torches suivantes.A second object of the invention is to propose a setting device in torches fitted with an automatic cutting device for the first torch then subsequent torches.

Un troisième but de l'invention est de proposer un dispositif de mise en torches muni d'un dispositif de ligature automatique de la première torche puis des torches suivantes.A third object of the invention is to propose a setting device in torches fitted with an automatic ligating device for the first torch then the following torches.

Enfin, encore un autre but de l'invention est de proposer un dispositif de mise en torches muni de moyens de commande automatique permettant de passer automatiquement de la confection d'une torche à celle de la torche suivante.Finally, yet another object of the invention is to propose a device in torches provided with automatic control means making it possible to automatically switch from making a torch to making the torch next.

Ces buts sont obtenus par un dispositif de mise en torches possédant les caractéristiques de la revendication 1, des formes d'exécution particulières ou variantes étant décrites dans les revendications dépendantes.These goals are achieved by a flare device having the features of claim 1, embodiments particulars or variants being described in the dependent claims.

Les moyens de guidage 30 peuvent être des rails ou des coulisses disposés à même le sol. Un bâti fixe 300 est monté en travers des moyens de guidage 30, étant aligné sur l'axe X de la ligne de production. Le bâti 300 ne peut pas se déplacer le long des moyens de guidage 30. Deux bâtis mobiles 31 sont montés sur les moyens de guidage respectifs 30, étant aptes à se déplacer le long desdits moyens de guidage entre une position écartée ou ouverte, comme représenté par exemple par le bâti 31 du poste A écarté du bâti 30, et une position rapprochée ou fermée, comme représenté par exemple par le bâti 31 du poste B rapproché du bâti 30. Des moyens d'entraínement motorisés non représentés sur les figures assurent les déplacements décrits ci-dessus des bâtis mobiles 31 des postes A et B. Des moyens de coulissement ou de glissement, représentés en 310 sur la figure 4, adaptés au type des moyens de guidage 30 permettent le déplacement des bâtis 31 des postes A et B.Figure 2 is a top view of some of the elements of the Figure 1. The torch making device 3 consists of two stations A and B for making a torch, the two stations A and B being arranged side by side in a direction perpendicular to the X axis schematically showing the longitudinal axis of the production line 1. The torch making device 3 comprises in particular two pairs of guide means 30 arranged perpendicular to the previously mentioned X axis and extending symmetrically on either side of said axis X. The guide means 30 can be rails or slides arranged on the floor. A fixed frame 300 is mounted across the guide means 30, being aligned on the axis X of the production line. Frame 300 cannot move along guide means 30. Two movable frames 31 are mounted on the means respective guide 30, being able to move along said means of guiding between a spread or open position, as shown for example by the frame 31 of the position A moved away from the frame 30, and a close position or closed, as shown for example by the frame 31 of station B close to the frame 30. Motorized drive means not shown in the figures ensure the movements described above of the movable frames 31 of the stations A and B. Sliding or sliding means, represented at 310 on the Figure 4, adapted to the type of guide means 30 allow the displacement of the frames 31 of stations A and B.

    Le bâti fixe 300 porte une première flasque 32 sur chacune de ses faces dirigées vers un bâti mobile 31. Chaque flasque 32 est montée de manière indépendante en rotation libre sur un palier 320, les deux dits paliers étant alignés selon un même axe, perpendiculaire à l'axe X et montés l'un derrière l'autre sur la portion centrale du bâti fixe 300. En allant à la figure 3, qui représente une flasque 32 vue de face, on voit qu'elle n'est pas constituée d'un disque plein mais de plusieurs segments de couronne circulaire 321, s'étendant radialement, régulièrement disposés autour d'un périmètre extérieur d'un disque central 322. La figure montre que la flasque 32 comprend six segments 321, mais elle pourrait en comprendre un nombre différent. Une première exigence du dispositif est que des espaces libres subsistent entre les segments 321, pour pouvoir effectuer les opérations de ligature qui seront décrites ultérieurement, alors qu'une deuxième exigence est que les segments offrent une résistance mécanique suffisante pour soutenir latéralement la torche en train d'être confectionnée. L'homme du métier saura concilier ces deux exigences contradictoires et trouver le nombre d'espaces entre deux segments ainsi que les dimensions desdits segments selon son application. Le diamètre extérieur exinscrit par les segments 321, respectivement le diamètre extérieur de la flasque 32 est légèrement plus grand que le diamètre maximum admissible d'une torche. The fixed frame 300 carries a first flange 32 on each of its faces directed towards a movable frame 31. Each flange 32 is mounted independently in free rotation on a bearing 320, the two so-called bearings being aligned along the same axis, perpendicular to the X axis and mounted one behind the other on the central portion of the fixed frame 300. Going to FIG. 3, which represents a flange 32 seen from the front, we see that it is not made up of a solid disc but of several circular crown segments 321, extending radially, regularly arranged around an outer perimeter of a central disc 322. The figure shows that the flange 32 comprises six segments 321, but it could include a different number. A first requirement of the device is that free spaces remain between the segments 321, in order to be able to carry out the ligating operations which will be described later, while a second requirement is that the segments provide sufficient mechanical strength to support laterally the torch being made. Those skilled in the art will be able to reconcile these two conflicting requirements and find the number of spaces between two segments as well as the dimensions of said segments according to its application. The outer diameter written out by segments 321, respectively the diameter outside of flange 32 is slightly larger than the maximum diameter admissible torch.

    Les flasques 32 des postes A et B sont identiques. Chacune peut donc être mise en rotation sur son propre palier 320, indépendamment de l'autre.The flanges 32 of stations A and B are identical. Each can therefore be rotated on its own bearing 320, independently of the other.

    En revenant à la figure 1, on voit que, de manière assez similaire, chaque bâti mobile 31 porte une deuxième flasque 33 faisant face à une flasque 32. Chaque flasque 33 est montée sur son bâti mobile 31 par un palier 330, chacune desdites flasque pouvant être entraínée indépendamment en rotation par son propre moyen d'entraínement motorisé 331.Returning to Figure 1, we see that, quite similarly, each movable frame 31 carries a second flange 33 facing a flange 32. Each flange 33 is mounted on its movable frame 31 by a bearing 330, each of said flange being able to be driven independently by rotation by its own motorized drive means 331.

    La constitution particulière de chaque flasque 33 est visible à la figure 4, qui montre une flasque 33 vue de face. Pour les mêmes raisons et avec les mêmes contraintes que décrites plus haut, les flasques 33 sont composées de segments de couronne circulaire 332 fixés sur un disque central 333. Contrairement aux flasques 32 décrites plus haut, le diamètre extérieur exinscrit par les segments 332 est inférieur au diamètre d'une torche. Chaque segment 332 porte un élément d'appui mobile 34 constitué ici d'un segment d'appui intérieur 340 et d'un segment d'appui latéral 341. L'élément mobile 34 est apte à être déplacé radialement sur une certaine distance le long du segment 332 par un actionneur 35. On voit sur la figure 4 que les segments d'appui intérieurs 340 forment des portions d'un cercle correspondant au diamètre intérieur de la torche à former. En revenant à la figure 2, notamment à sa portion de droite montrant le poste B avec la flasque 33 en position rapprochée de la flasque 32, on voit que la couche intérieure de spires de la torche à former, non représentée sur la figure afin de ne pas la surcharger, prendra appui sur les segments d'appui intérieurs 340, formant le diamètre intérieur de la torche, les spires latérales de chaque couche successive venant en appui latéral d'un côté sur les portions d'extrémités des segments 321 de la flasque 32 et de l'autre côté sur les segments d'appui latéraux 341.The particular constitution of each flange 33 is visible on the Figure 4, which shows a flange 33 front view. For the same reasons and with the same constraints as described above, the flanges 33 are composed of circular crown segments 332 fixed on a central disc 333. Unlike the flanges 32 described above, the outside diameter exinscribed by the segments 332 is less than the diameter of a torch. Each segment 332 carries a movable support element 34 consisting here of a segment internal support 340 and a lateral support segment 341. The movable element 34 is able to be moved radially over a certain distance along the segment 332 by an actuator 35. It can be seen in FIG. 4 that the segments internal support 340 form portions of a circle corresponding to the inside diameter of the torch to be formed. Returning to FIG. 2, in particular to its right portion showing station B with the flange 33 in position close to the flange 32, we see that the inner layer of turns of the torch to be formed, not shown in the figure so as not to overload it, will be supported on the interior support segments 340, forming the diameter inside the torch, the lateral turns of each successive layer coming in lateral support on one side on the end portions of segments 321 of the flange 32 and on the other side on the lateral support segments 341.

    La figure 5 montre une manière préférentielle selon laquelle l'élément mobile 34 est monté sur le segment 332 et est actionné par l'actionneur 35. Ici, chaque actionneur 35 comprend une vis sans fin 350 montée parallèlement au plan du segment 332 correspondant et s'étendant radialement. L'extrémité de chaque vis 350 distale du disque central 333 est munie d'un palier, non représenté, fixé à l'extrémité du segment 332 correspondant. Des moyens, non représentés mais connus de la technique, logés dans le disque central 333 sont aptes à mettre simultanément en rotation toutes les vis 350 d'une flasque 33. L'extrémité de chaque segment d'appui intérieur 340 connexe au segment 332 correspondant est munie de moyens de guidages 342 aptes à guider le segment d'appui intérieur 340 de manière à ce qu'il soit apte à se déplacer radialement le long du segment 332, tout en restant perpendiculaire audit segment. Les moyens de guidage 342 comprennent notamment un trou traversant 343 à travers lequel passe librement la vis sans fin 350. L'actionneur 35 comprend ensuite un bloc 351, lui aussi muni de moyens de guidage le long du segment 332 et comprenant en outre un trou taraudé 352 correspondant au filet de la vis 350. Un mouvement de rotation de la vis 350 dans un sens ou dans l'autre provoque donc un déplacement radial, dans un sens ou dans l'autre du bloc 351. Un vérin 353 est fixé par son cylindre au segment d'appui intérieur 340, la tige de piston 354 étant reliée par deux biellettes 355 et 356 d'une part à une portion du segment d'appui intérieur 340 proche des moyens de guidage 342 et d'autre part au bloc 351, les articulations entre ces différents éléments étant pivotantes. La tige de piston 354 ainsi que les biellettes 355 et 356 sont représentées sur la figure en une position intermédiaire, pour la bonne compréhension du fonctionnement du dispositif. Ainsi, pour un état donné du vérin 353, l'ensemble formé par le bloc 351, les biellette 356 et 355 et le segment d'appui intérieur 340 forme un bloc rigide. Un actionnement de la vis 350 dans un sens ou dans l'autre provoque donc un déplacement du segment d'appui intérieur 340 dans un sens ou dans l'autre, soit, en considérant l'ensemble des segments d'appui 340 actionnés simultanément, une augmentation ou une diminution du diamètre intérieur du cercle exinscrit à ces segments d'appui intérieurs formant le diamètre intérieur de la torche à former. Pour un réglage de diamètre déterminé comme décrit ci-dessus par les vis 350, l'actionnement des vérins 353, soit un déplacement des tiges de pistons 354 vers la gauche selon la figure 5, provoque un rapprochement des segments d'appui intérieurs 340 relativement aux blocs 351, qui eux restent fixes relativement au segment 332, provoquant ainsi une légère diminution du diamètre exinscrit par les segments d'appui intérieurs 340. Un actionnement en sens contraire des vérins 353 ramène les segments d'appui intérieurs 340 dans leur position initiale, respectivement au diamètre exinscrit réglé. Une telle fonction permet de diminuer temporairement légèrement le diamètre exinscrit par les segments d'appui intérieurs 340, de manière à pouvoir libérer une torche terminée comme on le verra plus loin. Le circuit hydraulique ou pneumatique des vérins 353 est conçu de telle manière qu'il est nécessaire d'appliquer une pression pour abaisser les segments d'appui intérieurs 340.Figure 5 shows a preferred way in which the movable element 34 is mounted on the segment 332 and is actuated by the actuator 35. Here, each actuator 35 comprises an endless screw 350 rising parallel to the plane of the corresponding segment 332 and extending radially. The end of each screw 350 distal from the central disc 333 is provided with a bearing, not shown, fixed to the end of segment 332 corresponding. Means, not shown but known in the art, housed in the central disc 333 are able to simultaneously rotate all the screws 350 of a flange 33. The end of each support segment interior 340 connected to the corresponding segment 332 is provided with means for guides 342 capable of guiding the internal support segment 340 so that that it is able to move radially along segment 332, while remaining perpendicular to said segment. Guide means 342 include a through hole 343 through which passes the worm 350 freely. The actuator 35 then comprises a block 351, also provided with guide means along segment 332 and comprising in in addition to a tapped hole 352 corresponding to the thread of the screw 350. A movement of rotation of the screw 350 in one direction or the other therefore causes a radial movement, in one direction or the other of the block 351. A cylinder 353 is fixed by its cylinder to the inner support segment 340, the piston rod 354 being connected by two links 355 and 356 on the one hand to a portion of the segment internal support 340 close to the guide means 342 and on the other hand to block 351, the articulations between these different elements being pivoting. The piston rod 354 and the links 355 and 356 are shown on the is in an intermediate position, for the correct understanding of the operation of the device. Thus, for a given state of the cylinder 353, the assembly formed by the block 351, the link 356 and 355 and the support segment interior 340 forms a rigid block. A screw 350 actuation in one direction or in the other therefore causes a displacement of the interior support segment 340 one way or the other, that is, considering all of the support segments 340 actuated simultaneously, an increase or a reduction of the inside diameter of the circle exinscribed to these support segments interiors forming the internal diameter of the torch to be formed. For an adjustment diameter determined as described above by screws 350, actuation cylinders 353, i.e. a displacement of the piston rods 354 to the left according to FIG. 5, brings the inner support segments closer together 340 relative to blocks 351, which remain fixed relative to the segment 332, thus causing a slight decrease in the diameter exinscribed by the internal support segments 340. Actuation in opposite directions of the cylinders 353 returns the interior support segments 340 to their initial position, respectively to the set exinscribed diameter. Such a function allows temporarily decrease the diameter excribed by the segments slightly internal support 340, so that a completed torch can be released as we will see later. The hydraulic or pneumatic circuit of the cylinders 353 is designed in such a way that it is necessary to apply pressure to lower the inner support segments 340.

    Les moyens de réglage du diamètre exinscrit par les segments intérieurs 340 peuvent évidemment être conçus différemment de ce qui est décrit ici ; par exemple la vis 350 pourrait être remplacée par des moyens à crémaillère, des moyens à vérin ou plus simplement le segment 332 pourrait comporter un certain nombre de positions déterminées sur lesquelles le bloc 351 pourrait être directement fixé. De même, les moyens d'abaissement temporaires des segments d'appui intérieurs 340 pourraient aussi être conçus différemment et être constitués par exemple de cames. En variante, il serait aussi possible de supprimer les moyens d'abaissement temporaire décrits, un abaissement temporaire pouvant être obtenu par les moyens de réglage de diamètre, par exemple la vis 350 engrenant directement dans le trou 343, qui est alors taraudé afin de coopérer avec la vis 350.The means of adjusting the diameter written out by the segments interiors 340 can obviously be designed differently from what is described here; for example the screw 350 could be replaced by means to rack, cylinder means or more simply segment 332 could have a certain number of determined positions on which the block 351 could be directly fixed. Likewise, the means of lowering temporary interior support segments 340 could also be designed differently and be made for example of cams. Alternatively, it would also possible to remove the temporary lowering means described, a temporary lowering obtainable by means of adjustment of diameter, for example the screw 350 meshing directly in the hole 343, which is then tapped in order to cooperate with the screw 350.

    On voit aussi sur la figure 5 que la position du segment d'appui latéral 341 est réglable le long du segment d'appui intérieur 340. Des moyens de fixation 344 permettent de fixer chaque segment d'appui latéral 341 sur des positions de fixation déterminées le long de chaque segment d'appui intérieur 340, permettant ainsi de régler la largeur de la torche à former.It can also be seen in FIG. 5 that the position of the support segment lateral 341 is adjustable along the inner support segment 340. Means 344 fasteners allow each lateral support segment 341 to be fixed on fixing positions determined along each interior support segment 340, thus making it possible to adjust the width of the torch to be formed.

    En variante, il serait aussi possible de supprimer les segments d'appui latéraux 341 et de prolonger les segments 332 jusqu'à former un diamètre de flasque équivalent au diamètre maximum d'une torche à former. Le réglage de largeur de la torche à former étant alors obtenu par un rapprochement adéquat de la flasque 33 relativement à la flasque 32.Alternatively, it would also be possible to delete the segments lateral supports 341 and extend the segments 332 until forming a flange diameter equivalent to the maximum diameter of a torch to be formed. The width adjustment of the torch to be formed then being obtained by a adequate approximation of the flange 33 relative to the flange 32.

    En revenant aux figures 2 et 4, on voit que chaque flasque 33 est munie d'un arbre de verrouillage 36 dont une extrémité est fixée au disque central 333 correspondant. L'autre extrémité des arbres 36 est munie d'un moyen de fixation 360, apte à se fixer dans un moyen de fixation correspondant 361 du disque central 322 des flasques 32. Un moyen d'actionnement 362 permet de commander l'ouverture ou la fermeture des moyens de fixation 360 de manière à fixer ensemble ou désolidariser les deux flasques 32 et 33. Sur la portion de droite de la figure 2 représentant le poste B, on voit que les moyens de fixation 360 et 361 coopèrent pour verrouiller ensemble les flasques 32 et 33, respectivement pour supporter les efforts latéraux exercés par la torche en formation sur ces deux flasques. La portion de droite de la même figure représentant le poste A, montre que les deux flasque 32 et 33 ont été désolidarisées.Returning to FIGS. 2 and 4, it can be seen that each flange 33 is provided with a locking shaft 36, one end of which is fixed to the disc central 333 correspondent. The other end of the shafts 36 is provided with a fixing means 360, suitable for fixing in a corresponding fixing means 361 of the central disc 322 of the flanges 32. An actuating means 362 allows the opening or closing of the fixing means to be controlled 360 so as to fix together or separate the two flanges 32 and 33. On the right portion of Figure 2 representing station B, we see that the means fixing 360 and 361 cooperate to lock together the flanges 32 and 33, respectively to support the lateral forces exerted by the torch in training on these two flanges. The right portion of the same figure representing station A, shows that the two flanges 32 and 33 have been separated.

    Sur les figures 2, 3 et 4 on voit encore que des moyens d'entraínement 37 sont prévus pour entraíner en rotation les flasques 32 de chaque poste A et B. Ces moyens peuvent être constitués par exemple d'au moins un toc d'entraínement comprenant une barre d'entraínement 370 en saillie sur le disque central 333 de chaque flasque 33 ainsi que d'une barre entraínée 371 en saillie sur le disque central 322 de chaque flasque 32. Lorsque les deux flasques 32 et 33 sont en position rapprochée, comme représenté sur la portion de droite de la figure 2 correspondant au poste B, la flasque 33, entraínée en rotation par ses moyens d'entraínement motorisés 331, entraíne en rotation la flasque 32 par l'intermédiaire des moyens d'entraínement 37 qui viennent d'être décrits. Plusieurs jeux de barres 370, 371 peuvent être prévus sur chaque jeu de flasques 32, 33.In FIGS. 2, 3 and 4 it can still be seen that means drive 37 are provided to rotate the flanges 32 of each station A and B. These means can consist, for example, of minus a training bar including a training bar 370 in projection on the central disc 333 of each flange 33 as well as a bar driven 371 projecting from the central disc 322 of each flange 32. When the two flanges 32 and 33 are in close position, as shown in the right portion of Figure 2 corresponding to station B, the flange 33, driven in rotation by its motorized drive means 331, rotates the flange 32 by means 37 which have just been described. Several busbars 370, 371 may be provided on each set of flanges 32, 33.

    Le dispositif de confection de torches 3 qui vient d'être décrit est de préférence complété d'un dispositif de trancanage 4 comme on le voit particulièrement sur la figure 2. Ce dispositif de trancanage est essentiellement semblable à d'autres dispositifs connus si ce n'est qu'il est apte à se déplacer sur des moyens de guidage 40 plus longs qu'habituellement, de manière à pouvoir alimenter successivement soit le poste A de gauche, soit le poste B de droite. Le dispositif de trancanage 4 peut être complété d'un dispositif de coupe 41, apte à couper le tube lorsqu'une première torche est pleine sur un premier poste. Les moyens de commande 7 sont aptes à régler la course de trancanage selon la position réglée des segments d'appui latéraux 341 sur les segments d'appui intérieurs 340, définissant ainsi la largeur de la torche à former.The torch-making device 3 which has just been described is of preferably supplemented with a cutting device 4 as seen particularly in FIG. 2. This cutting device is essentially similar to other known devices except that it is able to move on guide means 40 which are longer than usual, so as to be able to supply successively either station A on the left or station B of right. The cutting device 4 can be completed with a cut 41, able to cut the tube when a first torch is full on a first post. The control means 7 are capable of adjusting the travel of cutting according to the adjusted position of the lateral support segments 341 on the inner support segments 340, thereby defining the width of the torch to form.

    Une unité de ligature 5, particulièrement visible à la figure 2, peut venir utilement compléter le dispositif. Cette unité de ligature 5 est aussi essentiellement semblable à d'autres dispositifs connus si ce n'est qu'elle est apte à se déplacer sur des moyens de guidage 50 plus longs qu'habituellement, de manière à pouvoir alimenter successivement soit le poste A de gauche, soit le poste B de droite. L'unité de ligature 5 est composée d'un chariot 51, apte à se déplacer sur les moyens de guidage 50, ledit chariot portant deux bras de pose 52 aptes à s'écarter, comme représenté sur la figure ou à se rapprocher de manière à ce que leurs extrémités soient en contact, sous l'action d'un actuateur 53. L'unité comprend en outre une unité de dévidage d'un lien 54, apte à faire circuler le lien dans les bras 52 lorsqu'ils sont rapprochés et à tendre ce lien qui vient à être soudé par un dispositif de soudage 55. Les bras 52 peuvent être relevés pour que l'unité de ligature 5 passe d'un poste de confection de torche à l'autre. L'unité de commande 7 est aussi apte à régler la position du chariot 51 sur les moyens de guidage 50 en fonction de la position des segments d'appui latéraux 341, de manière à ce que le dispositif de soudage 55 opère sur une portion centrale de la largeur de la torche formée.A ligating unit 5, particularly visible in FIG. 2, can usefully complete the system. This ligature unit 5 is also essentially similar to other known devices except that it is able to move on longer guide means 50 that usually, in order to be able to supply successively either the station A on the left, that is, post B on the right. The ligature unit 5 is composed of a carriage 51, able to move on the guide means 50, said carriage carrying two laying arms 52 able to move apart, as shown in the figure or to approach so that their ends are in contact, under the action of an actuator 53. The unit further comprises a unit of unwinding of a link 54, able to circulate the link in the arms 52 when they are brought together and stretch this bond which comes to be welded by a device welding 55. The arms 52 can be raised so that the ligating unit 5 goes from one torch-making station to another. The control unit 7 is also able to adjust the position of the carriage 51 on the guide means 50 in depending on the position of the lateral support segments 341, so that the welding device 55 operates over a central portion of the width of the formed torch.

    Les moyens d'évacuation, visibles sur les figures 1 et 2, sont constitués, selon une forme d'exécution, de deux paires de rouleaux d'appui 60 et 61, chaque rouleau étant monté sur son propre moyen d'élévation. Chaque paire de rouleaux peut être suivie d'une rampe 62 conduisant à des guidages 63 où les torches terminées sont éventuellement stockées, étant prêtes à être enlevées par des moyens connus. On voit donc que par des moyens d'évacuation 6 décrits comme ci-dessus, les torches 20 terminées sont évacuées en aval de la ligne de production, et n'encombrent donc pas des régions latérales de la ligne de production ou du dispositif de confection de torches.The evacuation means, visible in FIGS. 1 and 2, are made up, according to one embodiment, of two pairs of support rollers 60 and 61, each roller being mounted on its own lifting means. Each pair of rollers can be followed by a ramp 62 leading to guides 63 where the completed torches are optionally stored, being ready to be removed by known means. So we see that by means 6 described as above, the torches 20 finished are evacuated downstream from the production line, and therefore do not encumber lateral regions of the production line or of the confection device torches.

    L'unité de commande 7 peut être propre au dispositif de confection de torches ou intégrée à l'unité de commande de la ligne de production. De préférence l'unité de commande comprend une unité à microprocesseur équipée d'un programme adéquat de gestion et de commande du dispositif de confection de torches. Des capteurs disposés aux endroits adéquats du dispositif de confection de torches indiquent l'état, position, vitesse, etc. de l'élément auxquels ils sont associés, l'unité de commande actionnant alors les divers entraínement ou actuateurs décrits.The control unit 7 can be specific to the manufacturing device of torches or integrated into the control unit of the production line. Of preferably the control unit includes a microprocessor unit equipped with an adequate management and control program for the making torches. Sensors placed in the appropriate places on the torch-making device indicates the state, position, speed, etc. of the element with which they are associated, the control unit then actuating the various drives or actuators described.

    Les divers dispositifs et éléments composant le dispositif de confection de torches ayant été décrits ci-dessus, on peut maintenant en décrire plus précisément son fonctionnement.The various devices and elements composing the device torch making having been described above, we can now describe more precisely how it works.

    En position de départ, au moins un des deux postes A ou B est fermé, c'est-à-dire que, comme représenté sur la portion droite de la figure 2 correspondant au poste B, la flasque 33 est rapprochée de la flasque 32, le verrouillage entre les moyens de fixation 360 et 361 ayant été effectué. La position radiale de chacun des segments d'appui intérieurs 340 a été réglée de manière à ce que le diamètre du cercle exinscrit par lesdits segments corresponde au diamètre intérieur désiré pour la torche. La position des segments d'appui latéraux 341 a été réglée selon la largeur désirée pour la torche.In the starting position, at least one of the two stations A or B is closed, i.e. as shown in the right portion of Figure 2 corresponding to station B, the flange 33 is brought closer to the flange 32, the locking between the fixing means 360 and 361 having been carried out. The radial position of each of the inner support segments 340 has been adjusted by so that the diameter of the circle written by said segments corresponds to the desired internal diameter for the torch. The position of lateral support segments 341 has been adjusted according to the desired width for the torch.

    Les bras 52 du dispositif de ligature 5 ont été relevés et le dispositif de trancanage 4 est amené de manière à pouvoir commencer la première spire à proximité d'une flasque 32 ou 33 du poste B.The arms 52 of the ligating device 5 have been raised and the device of cutting 4 is brought so as to be able to start the first turn near a flange 32 or 33 of station B.

    Lorsque la ligne de production 1 est mise en route et que l'extrémité de l'élément longiligne, soit du tube 2 sort du retireur 11, cette extrémité est amenée manuellement vers les poulies d'entrée du dispositif de trancanage 4. Le tube 20 traverse le dispositif de trancanage immobile puis est guidé vers un moyen d'accrochage connu de la technique disposé sur la flasque 32 ou 33 disposée en face du dispositif de trancanage 4 ou elle s'accroche. Le poste B peut être mis en rotation, par les moyens d'entraínement motorisés 331 la flasque 32 étant aussi mise en rotation lorsque les moyens d'entraínement 37 entrent en contact. Le dispositif de trancanage 4 est aussi activé afin de confectionner les spires successives sur les segments d'appui intérieurs 340. Lorsque la première couche de spires est terminée, le dispositif de trancanage confectionne les spires de la couche suivante et ainsi de suite.When production line 1 is started and the end of the elongate element, or of the tube 2 comes out of the withdrawer 11, this end is manually brought to the input pulleys of the cutting device 4. The tube 20 passes through the stationary cutting device and is then guided towards a attachment means known in the art disposed on the flange 32 or 33 arranged opposite the cutting device 4 or it hooks. Item B can be rotated by the motorized drive means 331 la flange 32 also being rotated when the drive means 37 come into contact. The cutting device 4 is also activated in order to make the successive turns on the inner support segments 340. When the first layer of turns is finished, the cutting device make the turns of the next layer and so on.

    Pour des torches de très grand diamètre, il est possible d'actionner le dispositif de ligature 5 afin de confectionner une ou plusieurs ligatures intermédiaires.For very large diameter torches, it is possible to activate the ligature device 5 in order to make one or more ligatures intermediaries.

    Lorsque la dernière couche de la torche est en voie d'être terminée, le dispositif de ligature est actionné au moins une fois afin de confectionner au moins une ligature avant d'activer le dispositif de coupe 41 du dispositif de trancanage 4.When the last layer of the torch is nearing completion, the ligating device is activated at least once in order to make up minus a ligature before activating the cutting device 41 of the cutting 4.

    Durant la confection de la première torche, comme décrit ci-dessus, le deuxième poste a été fermé et préparé comme indiqué plus haut pour le premier poste.During the making of the first torch, as described above, the second station was closed and prepared as indicated above for the first post.

    Dès que la coupe a été effectuée, le dispositif de trancanage 4 est rapidement amené en face du deuxième poste où la deuxième torche est confectionnée de la même manière que décrite plus haut.As soon as the cut has been made, the cutting device 4 is quickly brought in front of the second post where the second torch is made in the same way as described above.

    Durant ce temps, le dispositif de ligature 5 effectue quelques ligatures sur le périmètre de la torche afin de la maintenir assemblée, suite de quoi les rouleaux 61 et 61 sont élevés pour entrer en contact avec la surface périphérique extérieure de la torche terminée afin de la supporter. Les moyens 35 permettant de diminuer temporairement le diamètre exinscrit par les segments d'appui 340 sont activés de manière à ce que lesdits segments d'appui soient libérés de la torche. Les moyens de fixation 360 et 361 sont déclenchés, faisant qu'il est alors possible d'écarter le bâti mobile 31, respectivement la flasque 33, jusqu'à ce que les segments d'appui intérieurs 340 et la barre de fixation 36 soient entièrement dégagés du centre de la torche. En abaissant alors le rouleau d'appui 61, la torche se met à rouler sur la rampe 62 tout en étant guidée par les moyens de guidage 63.During this time, the ligating device 5 performs a few ligatures on the perimeter of the torch to keep it assembled, following what the rollers 61 and 61 are raised to come into contact with the surface outer device of the completed torch to support it. Ways 35 allowing the diameter exinscribed by the support segments 340 are activated so that said segments support are released from the torch. The fixing means 360 and 361 are triggered, making it possible to move aside the movable frame 31, respectively the flange 33, until the inner support segments 340 and the fixing bar 36 are entirely disengaged from the center of the torch. By then lowering the support roller 61, the torch begins to roll on the ramp 62 while being guided by the guide means 63.

    Les mêmes opérations se déroulent pour la deuxième torche lorsqu'elle est terminée. The same operations take place for the second torch when it is finished.

    En variante, il est aussi possible que les moyens de coupe ne soient pas prévus sur le dispositif de trancanage 4 mais soient associés à l'extrémité de la ligne de production 1, suivant immédiatement le retireur 11. La référence 12 de la figure 1 désigne ce dispositif de coupe. Cette variante peut être utilisée lorsque le temps nécessaire pour mettre en place le dispositif de trancanage 4 en face du nouveau poste à alimenter est trop grand relativement à la vitesse de production de la ligne. Dans ce cas le tube peut former une ou plusieurs sinusoïdes sur le sol, dans l'espace séparant le dispositif de coupe 12 du dispositif de trancanage 4, des moyens de guidage 13 pouvant être prévus afin de guider l'extrémité du tube dans cet espace.Alternatively, it is also possible that the cutting means are not not provided on the cutting device 4 but are associated with the end of production line 1, immediately following withdrawer 11. The reference 12 of Figure 1 denotes this cutting device. This variant can be used when the time required to set up the cutting 4 in front of the new substation to be supplied is too large relatively at line production speed. In this case the tube can form one or several sinusoids on the ground, in the space separating the cutting device 12 of the cutting device 4, guide means 13 can be provided to guide the end of the tube in this space.

    On voit donc qu'il est possible de confectionner des torches successives, sans qu'il soit nécessaire d'arrêter ou de ralentir la machine de production. Le processus peut être fortement automatisé, permettant de diminuer le nombre d'opérateurs nécessaires à la conduite de la ligne de production. Comme indiqué ce dispositif nécessite peu de place, notamment en hauteur, et ne nécessite pas l'entraínement de fortes masses ni de volumes importants.So we see that it is possible to make torches without successively stopping or slowing down the machine production. The process can be highly automated, allowing reduce the number of operators required to run the line production. As indicated, this device requires little space, especially in height, and does not require the training of heavy masses or volumes important.
