Description

La présente invention concerne un dispositif permettant de fermer de manière automatique une torche constituée d'un élément longiligne assemblé en une pluralité de couches d'une pluralité de spires, sur un poste de confection de torche, ainsi que de décharger ladite torche du poste de confection de torche.The present invention relates to a device for closing automatically a torch made up of an elongated element assembled in a plurality of layers of a plurality of turns, on a post making a torch, as well as discharging said torch from the torch making.

De nombreux éléments longilignes, comme par exemple des tubes, des profilés de n'importe quelle forme, des câbles isolés ou autres, sont obtenus selon un processus continu d'extrusion d'un matériau synthétique ou tout autre procédé de fabrication. Vu leur grande longueur, ces éléments sont bobinés sur une bobine à joues fixe disposée sur un bobinoir ou alors sur une fausse bobine constituée de deux flasques et d'un corps central formant fût, au moins une flasque pouvant être désolidarisée afin d'extraire du corps central la torche constituée de l'élément longiligne enroulé en une pluralité de couches d'une pluralité de spires. Un tel dispositif de confection de torches est décrit en particulier dans la demande 98811010.2.Many elongated elements, such as tubes, profiles of any shape, insulated cables or other, are obtained by a continuous process of extrusion of a synthetic material or any other manufacturing process. Given their great length, these elements are wound on a fixed cheek coil placed on a winder or else on a false coil consisting of two flanges and a central body forming a barrel, minus a flange that can be detached in order to extract from the central body the torch consisting of the elongated element wound in a plurality of layers of a plurality of turns. Such a torch-making device is described in particular in application 98811010.2.

Généralement, lorsque la longueur requise de l'élément longiligne est atteinte, ledit élément est coupé légèrement en amont de l'endroit où la torche est confectionnée et un opérateur doit saisir l'extrémité coupée et la retenir afin qu'elle s'enroule correctement sur la dernière couche, avant qu'une ligature puisse être faite, manuellement ou par des moyens automatiques, afin de maintenir la bobine assemblée. Cette opération nécessite donc la présence d'un opérateur et n'est pas sans danger. Dans le cas où l'extrémité coupée est laissée libre sans être retenue durant un certain temps, la torche a tendance à se défaire, au mois sur sa couche supérieure, ce qui la rend moins compacte et moins rigide une fois que les ligatures sont faites.Generally, when the required length of the elongated element is reached, said element is cut slightly upstream from where the torch is made and an operator must grasp the cut end and the retain so that it wraps properly on the last layer, before a ligation can be done, manually or by automatic means, so to maintain the assembled coil. This operation therefore requires the presence of an operator and is not without danger. In case the cut end is left free without being retained for a certain time, the torch tends to fall apart, monthly on its upper layer, which makes it less compact and less rigid once the ligatures are made.

Par exemple, du document DE-A 41 42 262, on connaít une installation de confection de torches d'un élément longiligne, comprenant:

  • au moins un élément de bâti,
  • une première flasque destinée à former un appui latéral pour une torche en formation, ladite première flasque étant supportée par un arbre dans un palier du bâti, et pouvant être mise en rotation libre dans ce palier,
  • une deuxième flasque et un faux centre, supportés par un autre élément de bâti, ces éléments pouvant être solidarisés avec la première flasque afin de former une fausse bobine pour recueillir l'élément longiligne et l'assembler en une torche,
  • des moyens d'entraínement en rotation d'au moins l'une des flasques, de manière à enrouler l'élément longiligne sur le faux centre,
  • un dispositif de confection de ligatures.
For example, from document DE-A 41 42 262, there is known an installation for making torches of a long element, comprising:
  • at least one frame element,
  • a first flange intended to form a lateral support for a torch in formation, said first flange being supported by a shaft in a bearing of the frame, and being able to be set in free rotation in this bearing,
  • a second flange and a false center, supported by another frame element, these elements being able to be joined to the first flange in order to form a false coil to collect the elongated element and assemble it into a torch,
  • means for driving in rotation at least one of the flanges, so as to wind the elongate element on the false center,
  • a device for making ligatures.

Dans cette installation le dispositif de ligature comprend un moyen presseur destiné à exercer une action de pression contre l'élément longiligne juste à côté de la ligature.In this installation, the ligating device comprises a means presser intended to exert a pressure action against the elongated element right next to the ligature.

Une telle installation a des avantages, mais la demanderesse estime qu'avec ce type d'installation l'extrémité coupée d'un élément longiligne, après que celui-ci ait été coupé, n'est pas maintenue suffisamment de manière à conserver la torche, et notamment sa dernière couche, bien assemblée.Such an installation has advantages, but the applicant considers that with this type of installation the cut end of a long element, after that it has been cut, is not maintained sufficiently so as to keep the torch, and in particular its last layer, well assembled.

Après que la torche ait été ligaturée, il est nécessaire de la décharger du poste de confection de torche où elle a été assemblée. Des moyens séparés sont généralement prévus à cet effet. After the torch has been ligated, it is necessary to unload from the torch-making station where it was assembled. of the separate means are generally provided for this purpose.

Un premier but de l'invention est de proposer un dispositif permettant de maintenir l'extrémité coupée d'un élément longiligne après que celui-ci ait été coupé, de manière à conserver la torche, et notamment sa dernière couche, bien assemblée.A first object of the invention is to propose a device to maintain the cut end of a slender member after it has been cut, so as to keep the torch, and in particular its last layer, well assembled.

Un deuxième but de l'invention est de proposer que le dispositif ci-dessus permette que la finition de la torche puisse s'effectuer automatiquement, respectivement sans danger pour l'opérateur.A second object of the invention is to propose that the above device allows the torch to be finished automatically, respectively safe for the operator.

Un troisième but de l'invention est de permettre que le dispositif ci-dessus soit conçu de manière à permettre le déchargement d'une torche assemblée.A third object of the invention is to allow the above device is designed to allow the discharge of a torch Assembly.

Ces différents buts sont obtenus par un dispositif de fermeture et de déchargement possédant les caractéristiques mentionnées dans la partie caractérisante de la revendication 1. Des variantes ou autres formes d'exécution sont décrites dans les revendications dépendantes.These various aims are obtained by a closure device and unloading having the characteristics mentioned in the part characterizing of claim 1. Variants or other forms are described in the dependent claims.

Une forme d'exécution préférentielle d'un dispositif selon l'invention est décrite ci-dessous, la description étant à considérer en regard du dessin annexé comportant les figures où :

  • la figure 1 est une vue partiellement en coupe transversale d'un dispositif selon l'invention associé à un poste de confection de torche,
  • la figure 2 est une vue latérale du dispositif de la figure 1, et
  • les figures 3A à 3G représentent une succession d'étapes montrant le fonctionnement du dispositif selon l'invention.
    • A preferred embodiment of a device according to the invention is described below, the description being to be considered with regard to the appended drawing comprising the figures where:

  • FIG. 2 is a side view of the device in FIG. 1, and
  • FIGS. 3A to 3G represent a succession of steps showing the operation of the device according to the invention.

    • La figure 1 montre un poste de confection de torche 1 vu partiellement en coupe selon un plan perpendiculaire à l'axe longitudinal de la ligne de production de l'élément longiligne 2. Le poste de confection de torche 1 comprend un bâti 10 supportant une première flasque 11 destinée à former un appui latéral pour une torche 20 en formation. Cette première flasque 11 est supportée par un arbre 12 dans un palier 13 du bâti 10. La première flasque 11 peut être mise en rotation libre dans le palier 13. Une deuxième flasque 14 et un faux centre 15, supportés par un autre élément de bâti non représenté sur la figure, peuvent être solidarisés avec la première flasque 11 afin de former une fausse bobine permettant de recueillir l'élément longiligne 2 et l'assembler en une torche 20. Des moyens d'entraínement en rotation, non représentés sur la figure, permettent d'entraíner l'une et/ou l'autre des flasques 11,14, de manière à enrouler l'élément longiligne 2 sur le faux centre 15.Figure 1 shows a torch making station 1 seen partially in section along a plane perpendicular to the longitudinal axis of the production line for the elongated element 2. The torch-making station 1 comprises a frame 10 supporting a first flange 11 intended to form lateral support for a torch 20 in formation. This first flange 11 is supported by a shaft 12 in a bearing 13 of the frame 10. The first flange 11 can be rotated freely in the bearing 13. A second flange 14 and a false center 15, supported by another frame element not shown in the figure, can be secured to the first flange 11 to form a false coil allowing to collect the elongated element 2 and assemble it in a torch 20. Rotational drive means, not shown in the figure, allow to drive one and / or the other of the flanges 11,14, so to wind the elongate element 2 on the false center 15.

    Comme on le voit à la figure 2, la première flasque 11 représentée en traits discontinus est constituée d'un disque central 110 sur lequel une pluralité de segments de couronne circulaire 111 sont régulièrement disposés radialement, un espace libre subsistant entre deux segments 111 successifs. La figure montre aussi en traits discontinus le diamètre constitué par le faux centre 15 sur lequel la torche 20 sera assemblée.As seen in Figure 2, the first flange 11 shown in broken lines consists of a central disc 110 on which a plurality of circular crown segments 111 are regularly arranged radially, a free space remaining between two successive segments 111. The figure also shows in broken lines the diameter formed by the false center 15 on which the torch 20 will be assembled.

    Le dispositif de fermeture 3 est disposé coaxialement sur l'arbre 12, entre le bâti 10 et la première flasque 11. De manière générale, le dispositif 3 tourne librement sur l'arbre 12. Le dispositif 3 comprend une portion support 30, munie du palier lui permettant de tourner autour de l'arbre 12, un côté dudit support étant muni de deux vérins 31, 32, chacun d'entre eux actionnant un bras support coudé 310, 320, chacun desdits bras coudés étant muni d'une portion d'appui 311, respectivement 321 (voir figure 2). Comme indiqué précédemment le dispositif 3 peut tourner librement autour de l'arbre 12, il ne possède aucun moyen d'entraínement propre en rotation mais est par contre muni d'un dispositif d'indexation de technique connue, schématisé en 33. Le dispositif d'indexation 33 permet de verrouiller le dispositif 3 selon deux positions angulaires relativement au bâti 10, une première position basse, comme représentée aux figures 1 et 2, où les bras coudés 310 et 320 sont disposés en bas de la torche 20 et une deuxième position haute, décalée de 180° relativement à la première position où les bras coudés sont disposés au sommet de la torche 20 (voir figure 3C).The closing device 3 is arranged coaxially on the shaft 12, between the frame 10 and the first flange 11. In general, the device 3 rotates freely on the shaft 12. The device 3 comprises a support portion 30, provided with the bearing allowing it to rotate around the shaft 12, one side of said support being provided with two jacks 31, 32, each of them actuating a bent support arm 310, 320, each of said bent arms being provided with a support portion 311, respectively 321 (see FIG. 2). As indicated previously the device 3 can rotate freely around the shaft 12, it does not has no own drive in rotation but is on the other hand fitted with an indexing device of known technique, shown diagrammatically in 33. The indexing device 33 allows the device 3 to be locked in two angular positions relative to the frame 10, a first low position, as shown in Figures 1 and 2, where the bent arms 310 and 320 are arranged at the bottom of the torch 20 and a second high position, offset by 180 ° relative to the first position where the bent arms are arranged at the top of torch 20 (see FIG. 3C).

    Les deux vérins 31 et 32 agissent sur les deux bras supports coudés 310 et 320 pour les positionner selon une position de relâchement, comme représenté aux figures 1 et 2 où les deux portions d'appui 311 et 321 sont dégagées de la flasque 11 et de la torche 20, ou une position de serrage selon laquelle les deux portions d'appui 311 et 321 des bras support 310 et 320 sont engagées dans un espace séparant deux segments 111 et pressent la dernière couche constituant la torche 20.The two jacks 31 and 32 act on the two bent support arms 310 and 320 to position them in a relaxed position, as shown in Figures 1 and 2 where the two support portions 311 and 321 are disengaged from the flange 11 and from the torch 20, or a clamping position according to which the two support portions 311 and 321 of the support arms 310 and 320 are engaged in a space separating two segments 111 and pressing the last layer constituting the torch 20.

    De préférence les deux bras supports 310 et 320 peuvent être actionnés simultanément de même qu'indépendamment l'un de l'autre.Preferably the two support arms 310 and 320 can be operated simultaneously as well as independently of each other.

    Un détecteur de position angulaire 16 détecte la position angulaire relative de la flasque 11 relativement au dispositif de fermeture 3, respectivement relativement aux deux bras coudés 310 et 320, de manière à ce qu'un serrage des portions d'appui 311 et 321 ne puisse être commandé que lorsque lesdites portions d'appui sont dans un espace séparant deux segments 111, ceci afin de ne pas risquer un endommagement de l'un et/ou l'autre des deux bras coudés 310,320 ainsi que d'un segment 111.An angular position detector 16 detects the angular position relative of the flange 11 relative to the closing device 3, respectively with respect to the two bent arms 310 and 320, so that that a tightening of the support portions 311 and 321 can only be controlled when said support portions are in a space separating two segments 111, this in order not to risk damage to one and / or the other of the two bent arms 310,320 as well as a segment 111.

    De préférence, le dispositif 3 peut encore être muni d'un autre dispositif d'indexation de technique connue, schématisé en 34, apte à verrouiller le dispositif 3 selon un certain nombre de positions angulaires relativement à la flasque 11, dans lesquelles lesdites portions d'appui 311 et 321 peuvent s'engager entre deux segments 111 consécutifs. Lorsque le verrouillage 34 entre le dispositif 3 et la flasque 11 est enclenché, une mise en rotation de la flasque 11 entraíne la rotation du dispositif 3.Preferably, the device 3 can also be provided with another indexing device of known technique, shown diagrammatically at 34, suitable for lock the device 3 in a number of angular positions relative to the flange 11, in which said bearing portions 311 and 321 can engage between two consecutive segments 111. When the locking 34 between the device 3 and the flange 11 is engaged, a setting rotation of the flange 11 causes the rotation of the device 3.

    Le dispositif de fermeture 3 est commandé par une unité de commande 17, pouvant être propre au dispositif lui-même, pouvant être intégrée à l'unité de commande du poste de confection de torche ou pouvant être intégrée à l'unité de commande de la ligne de production. L'unité de commande 17 comprend de préférence une unité à microprocesseur munie d'un programme permettant d'effectuer les opérations de fermeture de la torche qui vont être décrites ci-dessous.The closing device 3 is controlled by a unit of control 17, which can be specific to the device itself, which can be integrated into the control unit of the torch-making station or capable of be integrated into the production line control unit. The unit of control 17 preferably comprises a microprocessor unit provided a program allowing to carry out the operations of closing the torch which will be described below.

    La figure 3A et les suivantes montrent schématiquement une torche 20 en cours d'être confectionnée et le fonctionnement du dispositif de fermeture et de déchargement 3. Sur ces figures seuls les éléments strictement nécessaires à la compréhension des opérations ont été représentés.FIG. 3A and the following diagrammatically show a torch 20 being assembled and the functioning of the closing and unloading 3. In these figures only the elements strictly necessary for understanding the operations have been shown.

    La figure 3A montre un élément longiligne 2 en cours de production, par un procédé d'extrusion ou autre, l'élément 2 se déplaçant comme indiqué par la flèche A, la torche 20 en cours d'assemblage étant en rotation, comme indiqué par la flèche B, le dispositif 3 est verrouillé en position basse contre le bâti du poste de confection de torche, les deux bras coudés 310 et 320 étant dégagés de la flasque et de la torche et est déverrouillé relativement à la flasque.FIG. 3A shows an elongated element 2 during production, by an extrusion or other process, the element 2 moving as indicated by arrow A, the torch 20 being assembled being in rotation, as indicated by arrow B, the device 3 is locked in the low position against the frame of the torch-making station, the two bent arms 310 and 320 being clear of the flange and torch and is unlocked relative to the flange.

    Lorsque la longueur désirée de l'élément 2 sur la torche 20 approche de la longueur désirée, un dispositif de ligature 18, de technique connue, muni de deux bras mobiles 180 un seul étant visible sur la figure, est approché de la torche 20 en voie de finition. La rotation du poste de confection de torche, respectivement de la torche 20 est arrêtée, sa position d'arrêt étant commandée par le détecteur de position angulaire 16 décrit plus haut, de manière à ce qu'un espace séparant deux segments 111 consécutifs de la flasque 11 se trouve en face des deux bras coudés 310 et 320. Le dispositif de fermeture 3 est déverrouillé relativement au bâti et est verrouillé relativement à la flasque. Simultanément, les deux vérins 31 et 32 sont actionnés afin que les deux portions d'appui 311 et 321 serrent la dernière couche de la torche 20. Une rotation d'une portion de tour de la torche 20 est alors commandée, entraínant le dispositif 3 par le verrouillage 34 entre le dispositif 3 et la flasque ou par les portions d'appui 311 et 321 serrées contre la couche supérieure de la torche 20, de manière à ce qu'un dispositif de coupe 19 ne soit actionné que lorsque la longueur du tronçon de l'élément 2 déjà sur la torche 20 additionnée à la longueur non encore sur la torche, jusqu'au point de coupe, corresponde à la longueur finale désirée de l'élément longiligne 2 sur la torche 20. A ce moment la rotation de la torche 20 est à nouveau stoppée, le dispositif de coupe 19 est actionné et l'exécution d'une première ligature 181 peut alors être commandée afin de maintenir au plus tôt la torche assemblée.When the desired length of element 2 on torch 20 approach the desired length, a ligature device 18, technique known, provided with two movable arms 180 only one being visible in the figure, is approached torch 20 nearing completion. The rotation of the garment station torch, respectively torch 20 is stopped, its stop position being controlled by the angular position detector 16 described above, from so that a space separating two consecutive 111 segments from the flange 11 is located opposite the two bent arms 310 and 320. The device for closure 3 is unlocked relative to the frame and is locked relative to the flange. Simultaneously, the two cylinders 31 and 32 are actuated so that the two support portions 311 and 321 clamp the last layer of the torch 20. A rotation of a portion of the torch 20's turn is then controlled, driving the device 3 by the lock 34 between the device 3 and the flange or by the support portions 311 and 321 clamped against the upper layer of the torch 20, so that a cutting device 19 is only actuated when the length of the section of element 2 already on the torch 20 added length not yet on the torch, up to the cutting point, corresponds to the desired final length of the elongate element 2 on the torch 20. At this moment the rotation of the torch 20 is again stopped, the device for section 19 is activated and the execution of a first ligature 181 can then be ordered to maintain the assembled torch as soon as possible.

    Cette étape est visible sur la figure 3B où on voit que le dispositif de coupe 3 a été entraíné en rotation d'une portion de tour et que la coupe de l'extrémité de l'élément longiligne 2 a été faite et qu'une première ligature 181 a été effectuée.This step is visible in Figure 3B where we see that the device section 3 has been driven in rotation by a portion of a tower and that the section of the end of the elongate element 2 was made and that a first ligature 181 Has been done.

    Sur la figure 3C on voit que la torche 20 a de nouveau été entraínée en rotation d'une portion de tour, entraínant le dispositif de fermeture 3 jusqu'à ce que ce dernier soit en position de manière à pouvoir être verrouillé en position haute sur le bâti. Les deux portions d'appui 311 et 321 serrent toujours la torche 20. L'extrémité de l'élément 2 non encore assemblée sur la torche 20 suit librement. Le dispositif de ligature confectionne la deuxième ligature 182.In Figure 3C we see that the torch 20 has again been driven in rotation of a portion of a tower, causing the closure device 3 to that the latter is in position so that it can be locked in high position on the frame. The two support portions 311 and 321 always tighten the torch 20. The end of the element 2 not yet assembled on the torch 20 follows freely. The ligature device makes up the second ligature 182.

    Sur la figure 3D, le dispositif de fermeture 3 reste verrouillé en position haute relativement au bâti mais est déverrouillé relativement à la flasque. Les deux vérins 31 et 32 sont actionnés afin de relâcher la torche 20 et celle-ci est entraínée en rotation d'une portion de tour.In FIG. 3D, the closing device 3 remains locked in high position relative to the frame but is unlocked relative to the flange. The two jacks 31 and 32 are actuated in order to release the torch 20 and it is rotated by a portion of a tower.

    Ensuite, comme on le voit sur la figure 3E, le mouvement de rotation de la torche 20 est stoppé, les deux vérins 31 et 32 sont actionnés afin que les portions d'appui 311 et 321 serrent à nouveau la torche 20, et une nouvelle ligature 183 est confectionnée.Then, as seen in Figure 3E, the rotational movement torch 20 is stopped, the two cylinders 31 and 32 are actuated so that the support portions 311 and 321 again tighten the torch 20, and a new ligature 183 is made.

    En variante, il est aussi possible que lors de la rotation de la torche entre l'étape de la figure 3D et celle de la figure 3E, une légère pression reste appliquée par les deux portions d'appui 311 et 321 sur la couche extérieure de la torche, de manière à presser l'extrémité libre de l'élément longiligne contre les spires déjà assemblées de la torche 20.Alternatively, it is also possible that when rotating the torch between the step of figure 3D and that of figure 3E, a slight pressure remains applied by the two bearing portions 311 and 321 on the outer layer of the torch, so as to press the free end of the elongate element against the already assembled turns of the torch 20.

    Les deux dernières opérations décrites relativement aux figures 3D et 3E sont ensuite répétées, jusqu'à ce que l'extrémité libre de l'élément 2 soit complètement assemblée sur la torche et maintenue par une ligature et que le nombre voulu de ligatures soit effectué sur la torche 20 afin de la maintenir rigidement.The last two operations described in relation to 3D figures and 3E are then repeated, until the free end of element 2 is completely assembled on the torch and held by a ligature and that the desired number of ligatures is made on torch 20 in order to maintain it rigidly.

    La figure 3F montre la torche 20 complètement terminée, un certain nombre de ligatures ayant été réalisées afin de la maintenir rigidement. Le dispositif de ligature a été éloigné et le dispositif de fermeture 3 a été ramené en position basse où il est à nouveau verrouillé sur le bâti. Les deux vérins 31 et 32 sont activés afin de serrer la torche 20. A ce stade, la deuxième flasque 14 et le faux centre 15 sont dégagés, par des moyens connus, de la flasque 11 et de la torche 20, cette dernière restant supportée par les deux bras supports 311 et 321.FIG. 3F shows the torch 20 completely finished, a certain number of ligatures having been made in order to keep it rigidly. The ligature device has been moved away and closure device 3 has been brought back in the low position where it is again locked on the frame. The two cylinders 31 and 32 are activated in order to clamp torch 20. At this stage, the second flange 14 and the false center 15 are released, by known means, from the flange 11 and torch 20, the latter remaining supported by the two support arms 311 and 321.

    La figure 3G montre l'utilisation du dispositif 3 pour le déchargement de la torche 20. Celle-ci étant supportée uniquement par les bras supports 311 et 321, il suffit maintenant d'abaisser légèrement le bras support 321, ou d'élever légèrement le bras support 311, pour que la torche 20 soit déséquilibrée et commence à pivoter pour se dégager du poste de confection de torche. Une rampe 35 et des moyens de guidage non représentés permettent de l'amener vers un poste de stockage intermédiaire d'où elle pourra être reprise par des moyens connus.Figure 3G shows the use of device 3 for unloading torch 20. The latter being supported only by the support arms 311 and 321, it is now sufficient to slightly lower the support arm 321, or to slightly raise the support arm 311, so that the torch 20 is unbalanced and begins to pivot to free itself from the garment station torch. A ramp 35 and guide means not shown allow it to be brought to an intermediate storage station from where it may be taken up by known means.

    Les différentes étapes mentionnées ci-dessus permettant de fermer et décharger une torche l'ont été uniquement à titre d'exemple possible d'un processus de fermeture et de déchargement. Des variantes, sont évidemment aussi envisageables, par exemple il n'est pas indispensable que la première ligature 181 soit effectuée dès que la coupe de l'extrémité de l'élément longiligne a été faite, elle peut par exemple être faite un peu plus tôt, lors du premier arrêt du poste de confection de torche, ou plus tard, la ligature 182 étant alors la première ligature effectuée sur la torche. D'autres variations du processus sont encore possibles.The different steps mentioned above to close and discharge a torch were only as a possible example of a closing and unloading process. Variants, are obviously also possible, for example it is not essential that the first ligature 181 is performed as soon as the end of the element is cut has been made, it can for example be made a little earlier, when first stop of the torch-making station, or later, the ligature 182 then being the first ligature performed on the torch. Other variations of processes are still possible.

    Le dispositif 3 a été décrit avec deux vérins 31 et 32, ceux-ci pouvant être des vérins hydrauliques ou pneumatiques. D'autres moyens d'actionnement des bras support coudés 310 et 320, par exemple à crémaillère, à vis sans fin ou d'autres moyens mécaniques peuvent aussi être envisagés.The device 3 has been described with two jacks 31 and 32, these can be hydraulic or pneumatic cylinders. Other ways of the elbow support arms 310 and 320, for example at rack, worm gear or other mechanical means can also be considered.

    Le dispositif de fermeture et de déchargement d'une torche a été décrit pour être incorporé de manière avantageuse à un poste de confection de torches tel que décrit dans la demande 98811010.2. Dans ce cas où le poste de confection de torches est double, on aurait donc deux dispositifs tels que décrit, un pour chaque poste. Il est évident qu'un tel dispositif peut être associé à des postes de confection de torche ayant des configurations différentes; l'homme du métier saura adapter les caractéristiques constructives et de fonctionnement décrites ci-dessus à celles du poste de confection de torche qu'il doit équiper.The device for closing and unloading a torch has been described to be advantageously incorporated into a garment making station torches as described in application 98811010.2. In this case, the post torch confection is double, so we would have two devices such as described, one for each position. It is obvious that such a device can be combined at torch-making stations having different configurations; those skilled in the art will be able to adapt the constructive and operation described above to those of the torch making station that he has to equip.

    De même, il n'est pas indispensable que les moyens décrits permettant de décharger la torche du poste de confection soient inclus dans le dispositif de fermeture de torche. Dans le cas où le poste de confection de torche est déjà muni d'un dispositif de déchargement le dispositif décrit pourrait être simplifié en prévoyant par exemple que les deux vérins 31 et 32 ne peuvent fonctionner que simultanément ou alors en ne prévoyant qu'un seul vérin.Likewise, it is not essential that the means described to discharge the torch from the garment station are included in the torch closing device. In the case where the garment torch is already equipped with an unloading device the device described could be simplified by providing for example that the two cylinders 31 and 32 do not can operate only simultaneously or with only one cylinder.

    Comme indiqué plus haut, les différentes opérations décrites ci-dessus sont de préférence effectuées sous la conduite de l'unité de commande 17. Ainsi, il est possible d'automatiser entièrement les opérations de finition de la torche de même que son déchargement du poste de confection de torche. Vu que l'opérateur n'a plus à saisir l'extrémité libre de l'élément longitudinal, ni même à pousser la torche terminée pour la dégager du poste de confection, d'importants risques de danger sont ainsi éliminés.As indicated above, the different operations described above are preferably carried out under the control of the control unit 17. Thus, it is possible to fully automate the finishing operations of the torch as well as its unloading from the torch-making station. Since the operator no longer has to grasp the free end of the longitudinal element, nor even pushing the finished torch out of the garment station, significant danger risks are thereby eliminated.
