Description

DISPOSITIF DE COWTRE-COLLAGE & A LA FLAMME A BRULBARS MOBILES
HORIZONTALEMEXT
La présente invention concerne le contre-collage à la flamme dans lequel une première bande continue d'une mousse thermofusible est déroulée continûment devant la flamme d'au moins un brflleur faisant toute la largeur de la bande avant d'être appliquée sur une seconde bande continue d'un matériau, par exemple textile, moyennant quoi la partie superficielle thermofondue de la mousse réalise le collage de la mousse sur le textile. Elle concerne plus particulièrement un dispositif de contre-collage équipé de brûleurs dont le déplacement par rapport aux cylindres de pression se fait selon un mouvement de translation sensiblement horizontal.COWTRE-BONDING & FLAME DEVICE WITH MOBILE BRULBARS
HORIZONTALEMEXT
The present invention relates to flame lamination in which a first continuous strip of hot-melt foam is continuously unrolled in front of the flame of at least one burner making the entire width of the strip before being applied to a second strip. continuous of a material, for example textile, whereby the thermofused surface portion of the foam achieves the bonding of the foam on the textile. It relates more particularly to a lamination device equipped with burners whose movement relative to the pressure cylinders is done in a substantially horizontal translational movement.

La technique de contre-collage à la flamme est bien connue. The flame lamination technique is well known.

L'installation pour sa mise en oeuvre comporte un certain nombre de cylindres de pression délimitant le parcours d'une part de la mousse de contre-collage et d'autre part du ou des matériaux, par exemple textiles, destinés à être collés sur une face ou sur les deux faces de la mousse. Elle comporte également des brflleurs généralement au nombre de deux, chacun étant monté transversalement et apte à produire une flamme à proximité de la mousse lors de son déplacement continu sur toute la largeur de celle-ci.The installation for its implementation comprises a certain number of pressure cylinders delimiting the path on the one hand of the lamination foam and on the other hand of the material or materials, for example textiles, intended to be glued to a face or on both sides of the foam. It also includes burners, generally two in number, each being mounted transversely and capable of producing a flame near the foam during its continuous movement over the entire width of the latter.

Dans les installations connues , lors du démarrage ou de l'arrêt de l'opération de contre-collage, chaque brûleur est soumis à un déplacement en arc de cercle ayant pour effet simultanément d'éloigner la flamme de la mousse et de la dévier du cylindre de pression. Ce déplacement est indispensable pour éviter l'inflammation de la mousse. Pour cela , le support du broyeur est solidaire d'un axe qui est suffisamment en retrait par rapport aux cylindres de pression pour que lors de sa rotation les deux effets précités soient obtenus. In known installations, when starting or stopping the lamination operation, each burner is subjected to a displacement in an arc of circle having the effect simultaneously of moving the flame from the foam and deflecting it from the pressure cylinder. This movement is essential to avoid ignition of the foam. For this, the support of the mill is secured to an axis which is sufficiently set back relative to the pressure cylinders so that during its rotation the two aforementioned effects are obtained.

Cependant la présence de cet axe et le basculement du support des brûleurs autour de cet axe augmentent les difficultés d'accès des cylindres pour l'opérateur lors du chargement du dispositif. However, the presence of this axis and the tilting of the burner support around this axis increase the difficulties of access of the cylinders for the operator when loading the device.

Or on a trouvé et c'est ce qui fait l'objet de l'invention un dispositif de contre-collage à la flamme qui pallie l'inconvénient précité. Ce dispositif est du type connu en ce qu'il comprend deux brûleurs et des cylindres de pression délimitant le parcours de la mousse et du ou des matériaux de contre-collage, notamment textile. Now we have found, and this is what is the subject of the invention, a flame lamination device which overcomes the aforementioned drawback. This device is of the type known in that it comprises two burners and pressure cylinders delimiting the path of the foam and of the lamination material (s), in particular textile.

Selon l'invention, les axes des cylindres de pression étant sensiblement dans le même plan vertical, chaque brtleur est équipé de moyens de translation sensiblement horizontale entre une position dite de flambage où ils sont à proximité de la mousse et une position dite de recul où ils sont éloignés de la mousse, et, de plus , le dispositif comporte des moyens d'injection d'air comprimé dirigés parallélement aux cylindres dans la zone d'action des brflleurs et dont le fonctionnement est coordonné à celui des moyens de translation, de telle sorte que l'air est injecté des que les brûleurs passent de la position de flambage à la position de recul et l'air est coupé dès que les brûleurs passent de la position de recul à la position de flambage
Le recul sensiblement horizontal du brflleur n'entraîne pas de déviation de la flamme par rapport à la mousse, et c'est l'injection simultanée d'air comprimé le long de la mousse dans la zone d'action du brûleur qui évite tout risque d'inflammation de la mousse.According to the invention, the axes of the pressure cylinders being substantially in the same vertical plane, each burner is equipped with substantially horizontal translation means between a so-called buckling position where they are close to the foam and a so-called recoiling position where they are distant from the foam, and, moreover, the device comprises means for injecting compressed air directed parallel to the cylinders in the area of action of the burners and the operation of which is coordinated with that of the means of translation, so that air is injected as soon as the burners move from the buckling position to the reverse position and the air is cut off as soon as the burners move from the reverse position to the buckling position
The substantially horizontal recoil of the burner does not cause the flame to deflect relative to the foam, and it is the simultaneous injection of compressed air along the foam into the burner action zone which avoids any risk foam inflammation.

Selon le mode préféré de réalisation , les moyens de translation sensiblement horizontale d'un brûleur consistent en deux chariots , chacun étant solidaire d'une extrémité du brûleur et coulissant sur un rail sensiblement horizontal , et en un vérin dont la tige est solidaire de l'un des chariots. According to the preferred embodiment, the means for substantially horizontal translation of a burner consist of two carriages, each being secured to one end of the burner and sliding on a substantially horizontal rail, and to a jack whose rod is secured to the 'one of the carts.

De préférence le dispositif comporte des cales de réglage, aptes à être positionnées sur les rails de guidage des chariots d'un brûleur et à limiter la course du vérin. Preferably, the device comprises adjustment shims, capable of being positioned on the guide rails of the carriages of a burner and of limiting the stroke of the jack.

D'autres avantages et caractéristiques ressortiront de la description qui va être faite d'un mode de réalisation d'un dispositif de contre-collage à la flamme à brûleurs mobiles horizontalement , donné à titre d'exemple non limitatif , illustré par le dessin annexé dans lequel
La figure unique est une représentation schématique de côté du dispositif.Other advantages and characteristics will emerge from the description which will be given of an embodiment of a flame lamination device with horizontally movable burners, given by way of nonlimiting example, illustrated by the appended drawing. in which

Le dispositif de contre-collage à la flamme comporte un bâti I dont on n'a représenté que la partie, fixée au sol 2 supportant à sa partie haute la hotte d'aspiration 6 et les trois cylindres de pression 3,4,5 , respectivement le cylindre central 3 qui est fixe, le cylindre supérieur 4 mobile verticalement et le cylindre inférieur 5 mobile verticalement . Chaque cylindre est entraîné en rotation à la même vitesse par des moyens non représentés, les cylindres supérieur 4 et inférieur 5 tournant dans le même sens (fléchie S) tandis que le cylindre central 3 tourne dans le sens inverse (flèche T). The flame lamination device comprises a frame I of which only the part has been shown, fixed to the ground 2 supporting at its upper part the suction hood 6 and the three pressure cylinders 3,4,5, respectively the central cylinder 3 which is fixed, the upper cylinder 4 movable vertically and the lower cylinder 5 movable vertically. Each cylinder is rotated at the same speed by means not shown, the upper 4 and lower 5 cylinders rotating in the same direction (deflected S) while the central cylinder 3 rotates in the opposite direction (arrow T).

Le bâti 1 comporte des montants verticaux , respectivement des montants avant 7, dans le sens du déplacement de l'article contre-collé 9 selon la flèche F, et des montants arriére 8. Les montants 7,8 les plus extérieurs délimitent un volume ayant la forme d'un parallélépipéde rectangle , à l'intérieur duquel sont placés les trois cylindres de pression 3,4 et 5, dont les axes de rotation, parallèles entre eux, sont orientés transversalement par rapport au déplacement de l'article 9. The frame 1 comprises vertical uprights, respectively uprights 7, in the direction of movement of the laminated article 9 according to arrow F, and rear uprights 8. The outermost uprights 7, 8 define a volume having the shape of a rectangular parallelepiped, inside which are placed the three pressure cylinders 3,4 and 5, the axes of rotation of which, parallel to each other, are oriented transversely to the displacement of the article 9.

Les montants 7,8, correspondant à un même côté du dispositif , sont reliés par trois traverses 10,11 et 12. Sur la traverse centrale 10 est monté le palier 13 de roulement de l'axe 17 de rotationdu cylindre central 3. Le cylindre 3, maintenu de chaque côté par des paliers 13 est fixe en position. The uprights 7,8, corresponding to the same side of the device, are connected by three crosspieces 10,11 and 12. On the central crosspiece 10 is mounted the bearing 13 for rolling the axis 17 of rotation of the central cylinder 3. The cylinder 3, held on each side by bearings 13 is fixed in position.

Sur la traverse supérieure il est fixé le vérin 14 dont la tige 15 est terminée par un cadre 16 dans lequel est monté le palier 18 de roulement de l'axe 19 de rotation du cylindre supérieur 4. On the upper cross member, the jack 14 is fixed, the rod 15 of which is terminated by a frame 16 in which the bearing 18 for rolling the axis 19 of rotation of the upper cylinder 4 is mounted.

Sur la traverse inférieure 12 est fixé le vérin 20 dont la tige 21 est terminée par un cadre 22 dans lequel est monté le palier 23 de roulement de l'axe 24 de rotation du cylindre.  On the lower cross member 12 is fixed the jack 20 whose rod 21 is terminated by a frame 22 in which is mounted the bearing 23 for rolling the axis 24 of rotation of the cylinder.

Ces moyens , qui sont usuels dans l'industrie textile, consistent dans des barres respectivement 29,30,31,32 sur lesquelles sont enfilés les tubes de support de la mousse 25, des tissus 26 et 27 et de l'article contre-collé 9, seule la dernière barre 32 étant mue en rotation pour entraîner l'article contre-collé 9 dans le sens de la flèche F. These means, which are usual in the textile industry, consist of bars respectively 29,30,31,32 on which are threaded the tubes for supporting the foam 25, the fabrics 26 and 27 and the laminated article 9, only the last bar 32 being rotated to drive the laminated article 9 in the direction of the arrow F.

Sur le parcours de la mousse 25, des tissus 26,27 et de l'article contre-collé 9 sont placées des barres de détour afin de régulariser la tension. Along the course of the foam 25, fabrics 26, 27 and of the laminated article 9 are placed detour bars in order to regulate the tension.

De part et d'autre du bâti I sont montés deux brûleurs 28 et 33. Chaque brûleur 28 est constitué d'une enceinte 34 de répartition du gaz à briller et d'une tête de flambage 35, par laquelle le gaz s'échappe et est enflammé . La tête de flambage 35 est parallèle aux cylindres de pression ; sa longueur est sensiblement la même que celle desdits cylindres. L'enceinte 34 de répartition de chaque brflleur 28,33 est raccordée par au moins une conduite à une alimentation en gaz ou en mélange air-gaz approprié au flambage. On either side of the frame I are mounted two burners 28 and 33. Each burner 28 consists of an enclosure 34 for distributing the gas to be shined and of a buckling head 35, through which the gas escapes and is on fire. The buckling head 35 is parallel to the pressure cylinders; its length is substantially the same as that of said cylinders. The enclosure 34 for distributing each burner 28,33 is connected by at least one pipe to a gas or air-gas mixture suitable for buckling.

Le premier brûleur 28 est situé à proximité de la partie basse du cylindre supérieur 4, sa tête de flambage 35 étant dirigée vers celui-ci. Il est , sur la figure, à droite du bâti ), c'est-à-dire du côté où sont situées l'alimentation du tissu 27 et la réception de l'article contre-collé 9. The first burner 28 is located near the lower part of the upper cylinder 4, its buckling head 35 being directed towards the latter. It is, in the figure, to the right of the frame), that is to say on the side where the supply of the fabric 27 and the reception of the laminated article 9 are located.

Le second brûleur 33 est situé à proximité de la partie basse du cylindre central 3. Il est , sur la figure , a gauche du bâti 1, c'est-à-dire du côté où est située l'alimentation de la mousse 25 et du tissu 26. The second burner 33 is located near the lower part of the central cylinder 3. It is, in the figure, to the left of the frame 1, that is to say on the side where the supply of foam 25 is located and fabric 26.

Chacun des brûleurs 28 est fixé à ses deux extrémités sur un chariot 39 ayant à sa partie inférieure deux roulettes 40,41 libres en rotation et à sa partie avant une avancée 42 formant butoir. A chaque chariot 39 correspond un rail de guidage 43 fixé perpendiculairement au montant 7 du bâti 1. Ainsi le brûleur 38 repose par l'intermédiaire des chariots 39 sur deux rails de guidage , sur lesquels il peut se déplacer horizontalement. Ce déplacement est obtenu grâce au vérin 44 dont le corps est solidaire du rail 43 et dont l'extrémité libre de la tige 46 est fixée au chariot 39. Each of the burners 28 is fixed at its two ends to a carriage 39 having at its lower part two rollers 40,41 free to rotate and at its front part an advanced 42 forming a stopper. Each carriage 39 corresponds to a guide rail 43 fixed perpendicular to the upright 7 of the frame 1. Thus the burner 38 rests via the carriages 39 on two guide rails, on which it can move horizontally. This displacement is obtained thanks to the jack 44 whose body is integral with the rail 43 and whose free end of the rod 46 is fixed to the carriage 39.

Contre le montant vertical 7 et en avant de l'avancée 42 du chariot 39 sont disposées des cales 47 destinées à bloquer le déplacement du chariot 39 et donc limiter la course du vérin 44. Against the vertical upright 7 and in front of the advance 42 of the carriage 39 are arranged shims 47 intended to block the movement of the carriage 39 and therefore limit the stroke of the jack 44.

Le réglage de la position de flambage en fonction des paramètres de fonctionnement du dispositif et en particulier la force de collage souhaitée est obtenue en choisissant l'épaisseur de la cale 47 de manière à ajuster la distance entre la mousse 25 et la tête de flambage 35.The setting of the buckling position as a function of the operating parameters of the device and in particular the desired bonding force is obtained by choosing the thickness of the wedge 47 so as to adjust the distance between the foam 25 and the buckling head 35 .

Sensiblement dans le plan de la tette de flambage 35 de chacun des brûleurs 28 est fixéeau montant 7 du bâti une buse 48 d'injection d'air comprimé, raccordée à une source d'air comprimé non représentée. Cette buse 48 est dirigée vers la zone d'action du brûleur 28 correspondant , parallèlement aux cylindres 3,4,5. Significantly in the plane of the buckling plate 35 of each of the burners 28 is fixed to the upright 7 of the frame a nozzle 48 for injecting compressed air, connected to a source of compressed air not shown. This nozzle 48 is directed towards the zone of action of the corresponding burner 28, parallel to the cylinders 3,4,5.

On a représenté par des fléches sur les tracés représentant la mousse 25, les tissus 26,27 et l'article contre-collé 9, la direction prise par chacun de ces éléments au cours du fonctionnement du dispositif , pour la réalisation d'un article 9 composé d'une mousse 25 sur chaque face de laquelle est contre-collé un tissu respectivement 25,26. The directions taken by each of these elements during the operation of the device, for the production of an article, have been represented by arrows on the lines representing the foam 25, the fabrics 26, 27 and the laminated article 9. 9 composed of a foam 25 on each face of which a fabric 25.26 is laminated respectively.

Le contre-collage est réalisé de la manière suivante. La mousse 25 s'enroule successivement sur une portion de la périphérie du cylindre supérieur 4, du cylindre central 3 et du cylindre inférieur 5, étant entraînée par la rotation de ces trois cylindres . Le brûleur 28 étant allumé et dans sa position de flambage , la tige 46 du vérin 44 étant sortie, la flamme sortant de la tête de flambage 35 correspondante porte à l'état thermoplastique une certaine quantité du matériau constituant la mousse en regard de ladite tête de flambage 35. Le tissu 27 est enroulé autour du cylindre central 3 puis du cylindre inférieur 5. Laminating is carried out as follows. The foam 25 is wound successively over a portion of the periphery of the upper cylinder 4, of the central cylinder 3 and of the lower cylinder 5, being driven by the rotation of these three cylinders. The burner 28 being lit and in its flaming position, the rod 46 of the jack 44 being extended, the flame emerging from the corresponding flaming head 35 carries in the thermoplastic state a certain amount of the material constituting the foam opposite said head. of buckling 35. The fabric 27 is wound around the central cylinder 3 then of the lower cylinder 5.

Il pénètre sur le cylindre central 3 à proximité immédiate de la ligne de pression entre le cylindre supérieur 4 et le cylindre central 3. Dans cette zone, la partie de la mousse 25 à l'état thermoplastique est comprimée sur le tissu 27 , réalisant de ce fait le contre-collage de ce tissu 27 sur la mousse 25.It enters the central cylinder 3 in the immediate vicinity of the pressure line between the upper cylinder 4 and the central cylinder 3. In this zone, the part of the foam 25 in the thermoplastic state is compressed on the fabric 27, producing this makes the laminating of this fabric 27 on the foam 25.

Il en est de même pour le second brûleur 33, portant à un état thermoplastique une certaine quantité du matériau constituant l'autre face de la mousse 25. Cette partie est comprimée sur le tissu 26 lors de leur passage entre le cylindre central 3 et le cylindre inférieur 5. Ainsi après son passage entre les trois cylindres , la mousse 25 est collée par chacune de ses deux faces sur les deux tissus 27 et 26 et constitue l'article contre-collé 9. It is the same for the second burner 33, bringing to a thermoplastic state a certain amount of the material constituting the other face of the foam 25. This part is compressed on the fabric 26 during their passage between the central cylinder 3 and the lower cylinder 5. Thus after its passage between the three cylinders, the foam 25 is bonded by each of its two faces to the two fabrics 27 and 26 and constitutes the laminated article 9.

Les moyens de réglage du positionnement relatif des cylindres supérieur 4 et inférieur 5 par rapport au cylindre central 3 consistent en deux cales 45a,b placées dans des logements faisant face aux cadres 16,22 lors de leur déplacement. The means for adjusting the relative positioning of the upper 4 and lower 5 cylinders relative to the central cylinder 3 consist of two wedges 45a, b placed in housings facing the frames 16, 22 during their movement.

Un logement comprend une traverse 36 montée entre les deux montants 7,8 et formant le fond du logement et , au moins pour le logement inférieur correspondant au cadre 22, deux portions 37,38 de traverse montées sur l'un 7 et l'autre 8 montants. Ces deux portions de traverse 37,38 maintiennent la cale 45 dans son logement , lorsque la tige 21 du vérin 20 est rentrée. La dimension du logement est telle qu'il est possible d'y introduire des cales 45 de différentes épaisseurs de manière à régler la course correspondante du vérin et donc la force de compression des cylindres sur la mousse en fonction des paramètres de fonctionnement du dispositif et en particulier de l'épaisseur de la mousse 25. Les cales 45a,b placées dans le logement forment butée pour les cadres 16,22 qui se déplacent verticalement entre les deux portions de traverse (37,38) , règlent la position relative des cylindres supérieur 4 et inférieur 5 par rapport au cylindre central 3, et par conséquent l'écartement entre ceux-ci.A housing comprises a crosspiece 36 mounted between the two uprights 7,8 and forming the bottom of the housing and, at least for the lower housing corresponding to the frame 22, two portions 37,38 of the crossmember mounted on one 7 and the other 8 uprights. These two cross-section portions 37, 38 maintain the wedge 45 in its housing, when the rod 21 of the jack 20 is retracted. The size of the housing is such that it is possible to introduce shims 45 of different thicknesses therein so as to adjust the corresponding stroke of the jack and therefore the compression force of the cylinders on the foam as a function of the operating parameters of the device and in particular of the thickness of the foam 25. The shims 45a, b placed in the housing form a stop for the frames 16, 22 which move vertically between the two cross-section portions (37, 38), regulate the relative position of the cylinders upper 4 and lower 5 relative to the central cylinder 3, and therefore the spacing between them.

En fonction de la force de collage souhaitée , le réglage correspond généralement à un écrasement de la mousse de I à 2mm, c'est-à-dire que l'épaisseur des cales est choisie en sorte que la valeur de l'écartement entre les cylindres soit inférieure à l'épaisseur de la mousse 25 de ] à 2 mm. Depending on the desired bonding force, the setting generally corresponds to a crushing of the foam from I to 2mm, that is to say that the thickness of the shims is chosen so that the value of the spacing between the cylinders is less than the thickness of the foam 25 from] to 2 mm.

On comprend que pour l'introduction de la mousse 25 et des tissus 26,27 , les cylindres supérieur 4 et inférieur 5 doivent être écartés du cylindre central 3, les tiges 15,21 des vérins
14,20 étant rentrées, et que les brûleurs 28,33 sont dans la position de recul et les buses 48 d'injection sont en fonctionnement.It is understood that for the introduction of the foam 25 and of the fabrics 26, 27, the upper 4 and lower 5 cylinders must be separated from the central cylinder 3, the rods 15, 21 of the jacks
14,20 being retracted, and the burners 28,33 are in the recoil position and the injection nozzles 48 are in operation.

Le dispositif comprend aussi des moyens de commande , non représentés sur la figure , assurant la commande synchronisée de tous les organes du dispositif selon un programme pré-établi, lors du démarrage et de l'arrêt de l'opération de contre-collage. Une fois la mousse introduite autour des cylindres et les tissus positionnés sur la face correspondante de la mousse grâce par exemple à un ruban adhésif , le démarrage s'effectue par la commande simultanée des vérins 14,20 de déplacement des cylindres de pression, la commande simultanée des vérins 44 de déplacement des chariots 39 de chaque brûleur 28,33 , les amenant de la position de recul à la position de flambage , l'arrêt des buses 48 d'injection d'air comprimé et la rotation des axes 17,19,24 des cylindres de pression et de l'arbre 32 de réception de l'article contre-collé 9. The device also includes control means, not shown in the figure, ensuring the synchronized control of all the organs of the device according to a pre-established program, when starting and stopping the laminating operation. Once the foam has been introduced around the cylinders and the fabrics have been positioned on the corresponding face of the foam, for example using an adhesive tape, the start-up is carried out by the simultaneous control of the cylinders 14, 20 for moving the pressure cylinders, the control cylinders 44 for moving the carriages 39 of each burner 28,33, bringing them from the backward position to the buckling position, stopping the nozzles 48 for injecting compressed air and rotating the axes 17,19 , 24 of the pressure cylinders and of the shaft 32 for receiving the laminated article 9.

Dans l'exemple ci-dessus décrit de réalisation, les cylindres de pression avaient un même diamètre de 200mm.  In the example described above of embodiment, the pressure cylinders had the same diameter of 200mm.

L'invention n'est pas limitée au mode de réalisation qui a été décrit à titre d'exemple non exhaustif , mais en couvre toutes les variantes. Bien sur elle s'applique aussi au contre-collage une seule face , et non uniquement au contre-collage double face décrit ci-dessus.  The invention is not limited to the embodiment which has been described by way of non-exhaustive example, but covers all variants thereof. Of course, it also applies to single-sided lamination, and not only to double-sided lamination described above.
