Abstract

The device for the continuous bonding of strips comprises two modules (16, 17) longitudinally movable by two cylinders (25, 26) and bearing cutting elements (50, 45) and mobile celotape holders (47, 48, 49). The end of the prepared strip (6) is first fixed on the first module (16) with a clip (35), and the prepared bobbin (3) is blocked. For the bonding, the unwinding bobbin (5) is blocked with a clip (20), the strips are cut with a cutter (50), then the modules (16, 17) are moved in opposite directions to bring the mobile cellotape holders (47, 48) in the gluing area and to move apart simultaneously the strip chutes. The mobile cellotape holders (47, 48) apply the cellotape on both surfaces of the strips to be bonded, then the clip (20) is loosened. Thus the preparation of the strips is made much easier, and the device ensures a particularly reliable but inexpensive bonding.

Description

DISPOSITIF DE COLLAGE DE BANDES EN CONTINU CONTINUOUS BANDING DEVICE
La présente invention concerne les dispositifs permettant de réaliser un défilement continu d'une bande par solidarisation de plusieurs bandes les unes à la suite des autres . Les bandes se présentent enroulées sur des bobines, et la solidarisation intervient lorsqu'on arrive en fin de déroulement d'une bobine pour commencer le déroulement de la bobine suivante L'invention s'applique notamment aux bandes destinées à former des sachets pour emballage . On connaît en particulier un dispositif de ce genre, décrit dans le document EP 0 182 724 A. Un tel dispositif permet de coller des bandes en continu, en solidarisant le début d'une bande en attente et la fin d'une bande déroulante Des moyens de coupe permettent de couper les extrémités des bandes à solidariser Deux rouleaux opposés placés de part et d'autre des bandes permettent de maintenir longitudmalement en correspondance, dans une zone de maintien, les tronçons d'extrémité de bandes a solidariser Des moyens de collage, comprenant un support mobile et les rouleaux opposés, permettent d'appliquer un ruban adhésif simple face dans la zone de collage recouvrant les extrémités des bandes à solidar.ser Les ccuteaux sont disposes en une position longitudinale fixe, en amont des rouleaux Les rouleaux sont fixes en position longitudinale , et peuvent se déplacer transversalement Le support mobile est pivotant a our d'un axe fixeThe present invention relates to devices making it possible to carry out a continuous movement of a strip by securing several strips one after the other. The strips are wound on reels, and the joining occurs when the end of the unwinding of a reel begins to start the unwinding of the following reel. The invention applies in particular to strips intended to form sachets for packaging. In particular, a device of this type is known, described in document EP 0 182 724 A. Such a device makes it possible to glue strips continuously, securing the start of a waiting strip and the end of a rolling strip Des cutting means make it possible to cut the ends of the strips to be joined Two opposite rollers placed on either side of the strips make it possible to maintain longitudinally in correspondence, in a holding zone, the end sections of strips to be joined Adhesive means , comprising a movable support and the opposite rollers, make it possible to apply a single-sided adhesive tape in the bonding zone covering the ends of the strips to be joined. The cutters are arranged in a fixed longitudinal position, upstream of the rollers The rollers are fixed in the longitudinal position, and can move transversely The movable support is pivotable to a fixed axis
Au cours du déroulement de la bande déroulante, on positionne une longueur d'adhésif à l'extrémité de la bande en attente, en utilisant le support mobile, puis on transfère la longueur dépassante de ruban adhésif sur l'un des rouleaux En fin de déroulement de la bande déroulante, les rouleaux pressent la bande déroulante sur la partie dépassante de ruban adhésif, coupent la chute de bande déroulante et assurent le collage par entraînement simultané des deux bandes entre les rouleauxDuring the unwinding of the unrolling strip, a length of adhesive is positioned at the end of the waiting strip, using the mobile support, then the excess length of adhesive tape is transferred to one of the rollers. unwinding of the unrolling tape, the rollers press the unrolling tape on the protruding part of adhesive tape, cut the drop of unrolling tape and ensure the bonding by simultaneous entrainment of the two bands between the rollers
Il s'avère que la préparation des rubans adhésifs en bout de la bande en attente est relativement longue et délicate, et le dispositif ne permet pas d'assurer de façon simple et économique la solidarisation des bandes par deux adhésifs collés sur l'une et l'autre des faces de bandeIt turns out that the preparation of the adhesive tapes at the end of the waiting strip is relatively long and delicate, and the device does not make it possible to ensure in a simple and economical way the joining of the strips by two adhesives glued on one and the other of the tape faces
On connaît également un dispositif de collage de bandes en continu décrit dans le document US 2,987,108 A, dans lequel les organes actifs sont répartis en un module supérieur et un module inférieur distincts l'un de l'autre, disposés de part et d'autre des bandes dans une zone d'assemblage. Les modules sont mobiles alternativement en sens inverses l'un de l'autre par rotation vers l'amont et vers l'aval de la zone d'assemblage. Les portions de bande peuvent être bloquées par une pince aval et un dispositif d'aspiration amont. Les moyens de collage et les moyens de coupe sont décalés longitud alement sur les modulesThere is also known a continuous tape bonding device described in document US 2,987,108 A, in which the members assets are divided into an upper module and a lower module distinct from each other, arranged on either side of the strips in an assembly area. The modules are movable alternately in opposite directions to each other by rotation upstream and downstream of the assembly area. The strip portions can be blocked by a downstream clamp and an upstream suction device. The bonding means and the cutting means are offset longitudinally on the modules
Un inconvénient important de ce dispositif est que, entre l'étape de coupe des bandes et l'étape de collage, les portions de bandes à coller ne sont pas maintenues latéralement, et peuvent ainsi se déformer II en résulte que les bandes à coller ne se retrouvent pas de maniera certaine bout à bout lors de l'étape de collage Un autre inconvénient est la difficulté pour fixer l'extrémité de bande en attente sur le ruban de collage, car l'extrémité est peu accessible. EXPOSE DE ' INVENTIONAn important drawback of this device is that, between the step of cutting the strips and the step of bonding, the portions of strips to be bonded are not held laterally, and can thus be deformed. It follows that the strips to be bonded do not There is no certain way to end-to-end during the bonding step. Another drawback is the difficulty in fixing the end of the band waiting on the bonding tape, since the end is not very accessible. STATEMENT OF THE INVENTION
Un objet de la présente invention est de concevoir un nouveau dispositif de collage de bandes en continu, dans lequel la préparation des rubans adhésifs soit plus simple et plus rapide, tout en assurant un collage fiable et résistant des bandes les unes à la suite des autres Un autre objet est de concevoir un tel dispositif dont la structure soit particulièrement simple et peu onéreuse, et dont le fonctionnement soit particulièrement fiableAn object of the present invention is to design a new device for gluing continuous strips, in which the preparation of adhesive tapes is simpler and faster, while ensuring reliable and resistant bonding of the strips one after the other.

Les bobines 3 et 4 tournent librement sur leur axe respectif 1 ou 2 , l'entraînement des bandes étant assure en aval du dispositif. Les axes supports 1 et 2 sont toutefois associes a des freins que l'on peut commander pour immobiliser sélectivement en rotation les bobines 3 et 4DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment illustrated in FIG. 1, the device for gluing continuous strips according to the invention comprises two horizontal support axes 1 and 2 intended to each receive a respective coil 3 or 4 carrying a strip. The device is shown in the figure in a state where the reel 4 supports a drop-down strip 5 soon at the end of the roll-out, and the reel 3 supports a standby strip 6 which will have to continue. The coils 3 and 4 rotate freely on their respective axis 1 or 2, the drive of the strips being provided downstream of the device. The support axes 1 and 2 are however associated with brakes which can be controlled to selectively immobilize the coils 3 and 4 in rotation.
La bande déroulante 5 est guidée linéairement dans une zone d'assemblage 7 entre un rouleau de guidage amont 8 et un rouleau de guidage aval 9 La direction de la bande 5 dans la zone d'assemblage définit la direction longitudinale du dispositif, et la bande 5 se déplace de l'amont vers l'aval En aval du rouleau de guidage aval 9 est dispose un dispositif tampon 10, dont la fonction est d'assurer l'accumulation réversible d'une certaine longueur de bande Dans la réalisation représentée sur la figure, le dispositif tampon 10 comprend une succession de rouleaux comprenant un premier rouleau fixe 11, puis un rouleau mobile 12 monté sur un chariot 13 coulissant selon la flèche 14, puis un rouleau fixe 15 Le chariot 13 coulisse selon la flèche 14 pour se rapprocher et s'éloigner des rouleaux fixes 11 et 15, en étant sollicité par des moyens élastiques non représentés sur la figure et tendant a l'éloigner des rouleaux fixes 11 et 15. Le dispositif tampon 10 permet que le défilement de bande déroulante 5 en aval du dispositif tampon 10 soit continu et indépendant du défilement en amont On peut ainsi arrêter momentanément le défilement des bandes à l'intérieur du dispositif de collage pour assurer leur solidarisation l'une à l'autre, sans perturber le défilement de bande en aval Dans la zone d'assemblage 7 se trouvent les organes actifs du dispositif de collage de bandes selon l'invention. Dans le mode de réalisation représenté sur la figure 1, les organes actifs sont répartis en un premier module 16 et un second module 17 distincts l'un de l'autre et disposés de part et d'autre des bandes 5 et 6 dans la zone d'assemblage Les modules 16 et 17 sont mobiles alternativement en sens inverses l'un de l'autre vers l'amont et vers l'aval de la zone d'assemblage comme illustré par les doubles flèches respectives 18 et 19 Dans le mode de réalisation de la figure 1, le mouvement des modules 16 et 17 est un mouvement de translation longitudinale selon la direction longitudinale des bandes dans la zone d'assemblage 7, et selon un mouvement d'amplitude déterminée entre un premier et un second état extrême Sur la figure 1, les modules 16 et 17 sont dans le premier état extrême, tandis que sur la figure 3 les modules 16 et 17 sont dans le second état extrême.The unwinding strip 5 is guided linearly in an assembly area 7 between an upstream guide roller 8 and a downstream guide roller 9 The direction of the strip 5 in the assembly area defines the longitudinal direction of the device, and the strip 5 moves from upstream to downstream Downstream of the downstream guide roller 9 there is a buffer device 10, the function of which is to ensure the reversible accumulation of a certain length of strip In the embodiment shown in the Figure, the buffer device 10 comprises a succession of rollers comprising a first fixed roller 11, then a movable roller 12 mounted on a carriage 13 sliding along arrow 14, then a fixed roller 15 The carriage 13 slides along arrow 14 to get closer and move away from the fixed rollers 11 and 15, being stressed by elastic means not shown in the figure and tending to move it away from the fixed rollers 11 and 15. The buffer device 10 allows the d unrolling of the unrolling strip 5 downstream of the buffer device 10 is continuous and independent of the upstream scrolling It is thus possible to temporarily stop the running of the bands inside the bonding device to ensure that they join together without disturbing downstream tape scrolling In the assembly area 7 are the active members of the tape bonding device according to the invention. In the embodiment shown in FIG. 1, the active members are distributed in a first module 16 and a second module 17 distinct from each other and arranged on either side of the strips 5 and 6 in the area The modules 16 and 17 are alternately movable in opposite directions from each other upstream and downstream of the assembly area as illustrated by the respective double arrows 18 and 19. embodiment of FIG. 1, the movement of the modules 16 and 17 is a movement of longitudinal translation in the longitudinal direction of the strips in the assembly zone 7, and according to a movement of determined amplitude between a first and a second extreme state Sur Figure 1, the modules 16 and 17 are in the first extreme state, while in Figure 3 the modules 16 and 17 are in the second extreme state.
Une pince de blocage 20 est adaptée pour bloquer sélectivement la bande déroulante 5 en aval des modules 16 et 17 et en amont du dispositif tampon 10. Comme précédemment indiqué, un frein de bobine, non représenté sur les figures, permet de bloquer la rotation de la bobine 3 en attente.A locking clamp 20 is adapted to selectively block the unwinding strip 5 downstream of the modules 16 and 17 and upstream of the buffer device 10. As previously indicated, a coil brake, not shown in the figures, makes it possible to block the rotation of coil 3 on standby.
Pour la suite de la description, on se référera tout d'abord a la figure 2 montrant les éléments du dispositif de collage à plus grande échelleFor the remainder of the description, reference will first be made to FIG. 2 showing the elements of the bonding device on a larger scale
Les modules 16 et 17 sont montés chacun à coulissement longitudinal selon des glissières longitudinales respectives 21 et 22 sur un support intermédiaire respectif 23 ou 24 dont la position longitudinale est fixe Les modules 16 et 17 sont entraînés en translation par des vérins respectifs 25 et 26, pilotés par un dispositif de commande Chaque support intermédiaire 23 ou 24 est déplaçable latéralement, selon une direction perpendiculaire au plan des bandes 5 et 6 dans la zone d'assemblage 7, par rapport à un support fixe respectif 27 ou 28, le déplacement des supports intermédiaires étant assuré par des vérins de serrage respectifs 29 ou 30 pilotés par le dispositif de commandeThe modules 16 and 17 are each mounted with longitudinal sliding according to respective longitudinal slides 21 and 22 on a respective intermediate support 23 or 24 whose longitudinal position is fixed The modules 16 and 17 are driven in translation by respective cylinders 25 and 26, controlled by a control device Each intermediate support 23 or 24 can be moved laterally, in a direction perpendicular to the plane of the strips 5 and 6 in the assembly area 7, relative to a respective fixed support 27 or 28, the movement of the supports intermediates being provided by respective clamping cylinders 29 or 30 controlled by the control device
Dans le mode de réalisation de la figure 2, chacun des modules 16 et 17 présente une forme générale parallélépipédique, limitée notamment par une surface d'appui comportant une portion intérieure 31 ou 32 de surface d'appui et une portion aval extérieure 33 ou 34 de surface d'appui Les portions intérieures 31 et 32 de surface d'appui sont en regard l'une de l'autre, de sorte que les bandes 5 et 6 défilent longitudmalement entre elles. Les portions aval extérieures 33 et 34 de surface d'appui sont orientées vers l'extérieur, par exemple à 90° par rapport aux portions intérieures 31 et 32 correspondantes de surface d'appui, de façon à être aisément accessibles à l'utilisateur.In the embodiment of FIG. 2, each of the modules 16 and 17 has a generally parallelepiped shape, limited in particular by a bearing surface comprising an inner portion 31 or 32 of bearing surface and a downstream outer portion 33 or 34 of surface support The inner portions 31 and 32 of the support surface are opposite one another, so that the strips 5 and 6 run longitudinally between them. The outer downstream portions 33 and 34 of the bearing surface are oriented outward, for example at 90 ° relative to the corresponding inner portions 31 and 32 of the bearing surface, so as to be easily accessible to the user.
Chaque module 16 ou 17 comprend un élément de blocage respectivement 35 ou 36, constitué par exemple d'une pince actionnée par un verin 37 ou 38 piloté par le dispositif de commande, et adapté pour solidariser l'extrémité de la bande en attente sur la portion aval extérieure correspondante 33 ou 34 de surface d'appui Par exemple, dans la position illustrée sur la figure 2, l'élément de blocage 35 solidarise l'extrémité de la bande en attente 6 sur la portion aval extérieure 33 de surface d'appui du module 16. Par contre, l'élément de blocage 36 du module 17 est relâchéEach module 16 or 17 comprises a blocking element respectively 35 or 36, constituted for example by a clamp actuated by a jack 37 or 38 piloted by the control device, and adapted to secure the end of the strip waiting on the corresponding external downstream portion 33 or 34 of support surface For example, in the position illustrated in FIG. 2, the blocking element 35 secures the end of the waiting band 6 on the external downstream portion 33 of the surface of module 16 support. On the other hand, the blocking element 36 of module 17 is released
Pour faciliter le coulissement des bandes 5 et 6 le long des surfaces d'appui des modules 16 et 17, chaque module peut comprendre, comme illustré sur la figure 2, un rouleau d'entrée tel que le rouleau 39 du module 16, et un rouleau de sortie tel que le rouleau 40 du module 16. Les portions intérieures 31 et 32 de surface r1' appui sont avantageusement munies de trous d'aspiration repartis sur leur longueur et relies à des moyens d'aspiration pneumatiques sche atiquement représentés 41, 42, 43 et 44. Les moyens d'aspiration sont commandés par le dispositif de commande, et permettent de plaquer l'une des bandes 5 ou 6 sur le module correspondant 17 ou 16, pendant les opérations de coupe, de collage ou de translationTo facilitate the sliding of the strips 5 and 6 along the bearing surfaces of the modules 16 and 17, each module can comprise, as illustrated in FIG. 2, an input roller such as the roller 39 of the module 16, and a output roller such as the roller 40 of the module 16. The interior portions 31 and 32 of surface 1 support are advantageously provided with suction holes distributed over their length and connected to dry pneumatic suction means 41 represented, 42, 43 and 44. The suction means are controlled by the control device, and allow one of the strips 5 or 6 to be pressed onto the corresponding module 17 or 16, during cutting, gluing or translating operations
Dans la réalisation illustrée sur la figure 2 , le premier module 16 comprend deux fentes 45 et 46 transversales décalées longitudmalement l'une par rapport à l'autre dans le sens de défilement des bandes, et comprend un support mobile d'adhésif 47 disposé entre les fentes 45 et 46In the embodiment illustrated in FIG. 2, the first module 16 comprises two transverse slots 45 and 46 offset longitudinally relative to one another in the direction of travel of the strips, and comprises a movable adhesive support 47 disposed between slots 45 and 46
Le second module 17 comprend deux supports mobiles d'adhésif 48 et 49 décalés longitudmalement dans le sens de défilement des bandes, et comprend un couteau 50 disposé entre les supports mobiles 48 et 49.The second module 17 comprises two mobile adhesive supports 48 and 49 offset longitudinally in the direction of travel of the strips, and comprises a knife 50 disposed between the mobile supports 48 and 49.
Chaque support mobile d'adhésif tel que les supports 47, 48 et 49 comporte une surface porteuse 51 conformée pour recevoir un ruban adhésif et le retenir par aspiration. Ainsi, le support mobile d'adhésif est associé à des moyens d'aspiration pneumatiques relies à des trous d'aspiration répartis sur la surface porteuse 51 pour retenir un ruban adhésif plaqué contre ladite surface par sa face non collanteEach movable adhesive support such as supports 47, 48 and 49 has a support surface 51 shaped to receive an adhesive tape and retain it by suction. Thus, the mobile adhesive support is associated with pneumatic suction means connected to holes. suction distributed over the supporting surface 51 to retain an adhesive tape pressed against said surface by its non-sticky face
Chaque support mobile d'adhésif est déplaçable entre au moins une position de préparation dans laquelle sa surface porteuse telle que la surface 51 est accessible pour l'application du ruban adhésif, et une position de collage dans laquelle sa surface poiteuse 51 est en appui contre une bande à coller telle que la bande 6 ou la bande 5 pour transférer sur elle le ruban adhésif qu'elle porteEach movable adhesive support is movable between at least one preparation position in which its supporting surface such as the surface 51 is accessible for the application of the adhesive tape, and a bonding position in which its nasty surface 51 is pressed against a band to stick like band 6 or band 5 to transfer the adhesive tape she wears on her
Dans l'application illustrée, le support mobile 47 est en réalité déplaçable entre trois positions, selon deux mouvements successifs perpendiculaires. Par une translation transversale parallèlement au plan des bandes 5 et 6 à coller, c'est-à-dire perpendiculairement au plan de la figure 2, le support mobile 47 est déplaçable entie la position de préparation dans laquelle la surface porteuse est à l'écart des bandes 5 et 6 et une position d'attente illustrée sur la figure 2 dans laquelle la surface porteuse 51 est légèrement en retrait en regard des bandes à coller 5 et 6 Par un second mouvement de translation latérale, perpendiculairement au plan des bandes 5 et 6 à coller, le support mobile 47 est déplaçable entre la position d'attente précédemment définie et la position de collage précédemment définie Ce second mouvement de translation latérale peut être commandé par un verin 52, piloté par le dispositif de commande. Le premier mouvement de translation transversale peut être par exemple exécuté par actionnement manuel du support mobile 47, monté à coulissement dans le module 16. Les autres supports mobiles 48 et 49 peuvent avoir la même structure et le même fonctionnement.In the illustrated application, the mobile support 47 is actually movable between three positions, according to two successive perpendicular movements. By a transverse translation parallel to the plane of the strips 5 and 6 to be bonded, that is to say perpendicular to the plane of Figure 2, the movable support 47 is movable entie the position of preparation in which the carrier surface is separation of the strips 5 and 6 and a standby position illustrated in FIG. 2 in which the support surface 51 is slightly set back opposite the strips to be bonded 5 and 6 By a second lateral translation movement, perpendicular to the plane of the strips 5 and 6 to be bonded, the mobile support 47 is movable between the previously defined standby position and the previously defined bonding position. This second lateral translational movement can be controlled by a jack 52, controlled by the control device. The first transverse translational movement can for example be performed by manual actuation of the mobile support 47, slidably mounted in the module 16. The other mobile supports 48 and 49 can have the same structure and the same operation.
Le couteau 50 est déplaçable par translation latérale, perpendiculairement au plan des bandes 5 et 6 à coller, entre une position de retrait illustrée sur la figure 2 dans laquelle le couteau 50 est à l'écart des bandes 5 et 6, et une position de coupe illustrée sur la figure 3 dans laquelle le couteau sectionne les bandes 5 et 6 et pénètre dans la fente 45 elle-même conformée et disposée pour permettre cette pénétration.The knife 50 is movable by lateral translation, perpendicular to the plane of the strips 5 and 6 to be bonded, between a withdrawal position illustrated in FIG. 2 in which the knife 50 is away from the strips 5 and 6, and a position of section illustrated in Figure 3 wherein the knife cuts the strips 5 and 6 and enters the slot 45 itself shaped and arranged to allow this penetration.
Ainsi, comme on le voit sur la figure 2 notamment, les surfaces d'appui 31-34, les éléments de blocage 35, 36 et les trous d'aspiration associés aux moyens d'aspiration pneumatiques 41-44 constituent des moyens de maintien qui sont adaptés pour maintenir un tronçon d'extrémité de bande en attente 6 sur le module 16 initialement en amont, et pour maintenir le tronçon d'extrémité de bande déroulante 5 sur le module initialement en aval 17Thus, as can be seen in FIG. 2 in particular, the bearing surfaces 31-34, the locking elements 35, 36 and the suction holes associated with the pneumatic suction means 41-44 constitute holding means which are adapted to maintain an end section of strip on standby 6 on the module 16 initially upstream, and to maintain the end section of the unrolling strip 5 on the module initially downstream 17
Les moyens de collage constitués par les supports mobiles d'adhésif 47-49 et les moyens de coupe sont décalés longitudmalement sur les modules 16 et 17.The bonding means constituted by the movable adhesive supports 47-49 and the cutting means are offset longitudinally on the modules 16 and 17.
On choisit les amplitudes de mouvement de translation longitudinale des modules 16 et 17 de façon que, lorsque les modules sont dans l'un des états extrêmes tel qu'illustré par exemple sur la figure 2, les moyens de coupe constitués par le couteau 50 peuvent sectionner les bandes 5 et 6 en une position intermédiaire des tronçons d'extrémité de bande en attente 6 et de bande déroulante 5, et, lorsque les modules 16 et 1 1 ont ensuite été déplaces dans l'autre des états extrêmes tel qu'illustré sur la figure 4, les moyens de collage 47, 48 se trouvent en regard des bords extrêmes à coller des bandes et le mouvement relatif des modules 16 et 17 a déplacé les chutes d'extrémité à l'écart de la zone de collage des bandes. Pour cela, sur chaque module 16 ou 17, les moyens de collage 47-49 et les moyens de coupe 45, 50 sont décalés selon ladite amplitude déterminée. Ce fonctionnement est explicité en relation avec la suite des figures 2 à 5, ainsi que les figures 7 à 12The amplitudes of longitudinal translation movement of the modules 16 and 17 are chosen so that, when the modules are in one of the extreme states as illustrated for example in FIG. 2, the cutting means constituted by the knife 50 can section the strips 5 and 6 at an intermediate position of the end sections of the waiting strip 6 and the unrolling strip 5, and, when the modules 16 and 1 1 have then been moved into the other of the extreme states as illustrated in FIG. 4, the bonding means 47, 48 are located opposite the extreme edges to be bonded on the strips and the relative movement of the modules 16 and 17 has displaced the end falls away from the zone for bonding the strips . For this, on each module 16 or 17, the bonding means 47-49 and the cutting means 45, 50 are offset according to said determined amplitude. This operation is explained in relation to the rest of Figures 2 to 5, as well as Figures 7 to 12
Sur la figure 2, le dispositif est en attente les modules 16 et 17 sont écartés latéralement l'un de l'autre, permettant la libre circulation de la bande déroulante 5. Pendant cette circulation de la bande déroulante 5, l'utilisateur a passé l'extrémité de la bande en attente 6 entre les deux modules 16 et 17, et le tronçon d'extrémité de bande en attente longe la portion intérieure de surface d'appui 31 et est plaquée et solidarisée sur la portion aval extérieure 33 de surface d'appui par la pince 35 sollicitée par le vérin 37 La bobine en attente 3 est bloquée en rotation par son moyen de freinage La pince de blocage 20 est en position ouverte, autorisant le libre coulissement de la bande défilante 5In FIG. 2, the device is on standby, the modules 16 and 17 are separated laterally from one another, allowing the free circulation of the unrolling strip 5. During this circulation of the unrolling strip 5, the user has passed the end of the waiting band 6 between the two modules 16 and 17, and the waiting band end section runs along the inner portion of the bearing surface 31 and is pressed and secured to the downstream outer surface portion 33 support by the clamp 35 biased by the jack 37 The standby coil 3 is locked in rotation by its braking means The locking clamp 20 is in the open position, allowing the sliding band 5 to slide freely
Sur la figure 3, les modules 16 et 17 ont été déplacés latéralement dans leur position rapprochée, par actionnement des vérins 29 et 30 de serrage, de sorte qu'un faible espace existe entre les deux portions intérieures 31 et 32 de surface d'appui, favorisant le guidage des bandes 5 et 6 La pince de blocage 20 est alors serrée, pour bloquer le mouvement de la bande défilante 5, et les moyens d'aspiration pneumaticfues 41, 42, 43 et 44 maintiennent les tronçons de bande contre les modules 16 ou 17 correspondants dans la zone d'assemblage 7 Les deux modules 16 et 17 restent dans leur première position extrême qu'ils avaient en position d'attente de la figure 2, le premier module 16 étant en amont, le second module 17 étant en aval. Dès l'arrêt de la bande défilante 5, on actionne le couteau 50 qui tranche les deux bandes 5 et 6 et pénètre dans la fente 45, puis retourne en position de retraitIn FIG. 3, the modules 16 and 17 have been moved laterally in their close position, by actuation of the clamping cylinders 29 and 30, so that a small space exists between the two inner portions 31 and 32 of the bearing surface , favoring the guiding of the bands 5 and 6 The locking clamp 20 is then tightened, to block the movement of the moving strip 5, and the pneumaticfues suction means 41, 42, 43 and 44 hold the strip sections against the corresponding modules 16 or 17 in the assembly area 7 The two modules 16 and 17 remain in their first extreme position they had in the standby position of Figure 2, the first module 16 being upstream, the second module 17 being downstream. As soon as the moving strip 5 stops, the knife 50 is actuated which cuts the two strips 5 and 6 and enters the slot 45, then returns to the withdrawal position.
On déplace alors les modules 16 et 17 pai actionnement des venns correspondants 25 et 26, comme illustre sur la figure 4, pour amener le premier module 16 en position extrême aval et le second moduleThe modules 16 and 17 are then moved by actuation of the corresponding valves 25 and 26, as illustrated in FIG. 4, to bring the first module 16 to the extreme downstream position and the second module
17 en position extrême amont Pendant ce mouvement, les moyens d'aspiration pneumatiques 41-44 maintiennent le_. parties correspondantes de tronçons de bande en appui glissant contre les modules 16 ou 17 respectifs Dans ce second état extrême, les supports mobiles d'adhésif 47 et 48 se trouvent en regard 1 ' un de l'autre et simultanément en regard des extrémités correspondantes precoupées de la portion amont de bande en attente 6 et de la portion aval de bande déioulante 5 Le déplacement latéral des supports mobiles d'adhésif 47 et 48 permet alors d'appliquer les rubans adnésifs qu'ils portent, par leurs face;, adhésives, contre les faces correspondantes des extrémités de bande en attente 6 et de bande déroulante 5, pour effectuer un collage double face Un collage simple face peut être réalisé en plaçant un seul adhésif selon un seul côté17 in the upstream extreme position During this movement, the pneumatic suction means 41-44 maintain the. corresponding parts of strip sections in sliding contact against the respective modules 16 or 17 In this second extreme state, the movable adhesive supports 47 and 48 are located opposite one another and simultaneously opposite the corresponding precut ends of the upstream portion of waiting tape 6 and of the downstream portion of unrolling tape 5 The lateral displacement of the mobile adhesive supports 47 and 48 then makes it possible to apply the adhesive tapes which they carry, by their faces; against the corresponding faces of the ends of the waiting strip 6 and of the unrolling strip 5, for performing a double-sided bonding A single-sided bonding can be carried out by placing a single adhesive on one side
Sur la figure 5, les deux modules 16 et 1 sont alors déplacés latéralement à l'écart l'un de l'autre par actionnement des vérins respectifs 29 et 30, et l'on distingue les adhésifs 53 et 54 solidarisant l'extrémité amont de la bande en attente 6 et l'extrémité aval de la bande défilante 5 L'utilisateur peut alors retire) aisément les chutes constituées par l'extrémité aval 55 de la bande en attente 6 et l'extrémité amont 56 de la bande déroulante 5 Dans la position de cette figure, après déroulement de la bobine de bande 6, l'utilisateur pourra recommencer l'opération après avon adapté 'extrémité d une nouvelle bande sur le module 17, de façon symétrique de la position illustrée sur la figure 2 Les opérations de collage sont illustrées à nouveau sur les figures 7 à 9, pour représenter plus clairement les tronçons de bande avant et après collage • sur la figure 7, 1 ' actionnement du couteau 50 IIn Figure 5, the two modules 16 and 1 are then moved laterally away from each other by actuation of the respective cylinders 29 and 30, and there are adhesives 53 and 54 securing the upstream end of the waiting band 6 and the downstream end of the moving band 5 The user can then easily remove) the scraps formed by the downstream end 55 of the waiting band 6 and the upstream end 56 of the unrolling band 5 In the position of this figure, after unwinding of the tape reel 6, the user can repeat the operation after having adapted the end of a new strip on the module 17, symmetrically from the position illustrated in FIG. bonding operations are illustrated again in FIGS. 7 to 9, to more clearly represent the strip sections before and after bonding • in FIG. 7, the actuation of the knife 50 I
sectionne la bande en attente 6 et la bande déroulante 5, séparant un tronçon aval de bande en attente 55 du reste de la bande, et séparant un tronçon amont 56 de bande déroulante par rapport au reste de la bande. Entre les deux positions successives illustrées sur les figures 7 et 8 , le déplacement en translation des deux modules 16 et 17 déplace simultanément les deux tronçons 55 et 56 qui sont tenus sur les modules respectifs 16 et 17 par l'élément de blocage 35 (figure 3) ou par le moyen d'aspiration pneumatique 43 (figure 2) . Les tronçons 55 et 56 sont ainsi déplacés à l'écart de la zone de collage, et constitueront, les chutes de bande. Pendant le mouvement de translation des modules 16 et 17, l'extrémité 57 de la bande en attente 6 et l'extrémité 58 de la bande déroulante 5 sont bloquées longitudinalement respectivement par le frein de la bobine en attente 3 et par la pince de blocage 20, et sont, maintenues en appui glissant contre les portions intérieures 31 ou 32 de surfaces d'appui des modules respectifs 16 ou 17 par les moyens d'aspi ation pneumatiques respectifs 42 ou 44 (figure 2) . En fin de mouvement de translation (figure 8), ces extrémités à coller 57 et 58 se retrouvent alors face aux supports mobiles d'adhésif 47 et 48.cuts the standby strip 6 and the unwinding strip 5, separating a downstream section of waiting strip 55 from the rest of the strip, and separating an upstream section 56 of unwinding strip with respect to the rest of the strip. Between the two successive positions illustrated in FIGS. 7 and 8, the displacement in translation of the two modules 16 and 17 simultaneously displaces the two sections 55 and 56 which are held on the respective modules 16 and 17 by the locking element 35 (FIG. 3) or by the pneumatic suction means 43 (Figure 2). The sections 55 and 56 are thus moved away from the bonding zone, and will constitute the scrap of tape. During the translational movement of the modules 16 and 17, the end 57 of the standby strip 6 and the end 58 of the unwinding strip 5 are locked longitudinally respectively by the brake on the standby reel 3 and by the locking clamp. 20, and are kept in sliding contact against the inner portions 31 or 32 of the bearing surfaces of the respective modules 16 or 17 by the respective pneumatic suction means 42 or 44 (FIG. 2). At the end of the translational movement (FIG. 8), these ends to be bonded 57 and 58 are then faced with the mobile adhesive supports 47 and 48.
Sur la figure 9, après actionnement des supports mobiles d'adhésif 47 et 48 qui ont appliqué sur les bandes les adhésifs 53 et 54, la bande 5 se trouve solidarisée à la bande C et leur défilement longitudinal peut se poursuivre en relâchant la pince de blocage 20 et le frein de la bobine en attente 3.In FIG. 9, after actuation of the mobile adhesive supports 47 and 48 which have applied the adhesives 53 and 54 to the strips, the strip 5 is secured to the strip C and their longitudinal travel can continue by releasing the clamp blocking 20 and the coil brake on standby 3.
Les figures 10 à 12 illustrent le fonc ionnement symétrique du dispositif pour le changement suivant de bande. La bande 6 est devenue la bande déroulante, tandis que la bande 5 est devenue la bande en attente. L' actionnement du couteau 50 tranche les deux bandes 5 et 6. Sur la figure 11, le déplacement des modules dans le sens inverse déplace les chutes de bande et amène les supports mobiles d'adhésif 47 et 49 l'un en face de l'autre et en face des extrémités des bandes à coller. Sur la figure 12, après actionnement des supports mobiles d'adhésif 47 et 49, les deux bandes b et 6 sont collées et les chutes peuvent être enlevées.Figures 10 to 12 illustrate the symmetrical operation of the device for the next band change. Band 6 has become the drop-down band, while band 5 has become the standby band. The actuation of the knife 50 cuts the two strips 5 and 6. In FIG. 11, the displacement of the modules in the opposite direction displaces the falling strips and brings the movable adhesive supports 47 and 49 one opposite the 'other and opposite the ends of the strips to be glued. In FIG. 12, after actuation of the mobile adhesive supports 47 and 49, the two strips b and 6 are glued and the scraps can be removed.
On notera que, dans le mode de réalisation qui a été décrit, le premier module 16 comprend deux fentes 45 et 46 et un support mobile d'adhésif 47, tandis que le second module 17 comprend un couteau 50 et deux supports mobiles d'adhésif 48 et 49. Les figures 13 à 18 illustrent un mode de réalisation différent, dans lequel chaque module comprend deux supports mobiles d'adhésif décalés longitudinalement : le second module 17 comprend les mêmes éléments 48, 49 et 50 que dans le mode de réalisation précédent ; le premier module 16 comprend une seule fente 45 disposée entre deux supports mobiles d'adhésif 47 et 147.Note that, in the embodiment which has been described, the first module 16 comprises two slots 45 and 46 and a movable adhesive support 47, while the second module 17 comprises a knife 50 and two movable adhesive supports 48 and 49.
