Description

Dans les machines de fabrication de cigarettes ou de filtres fonctionnant en continu, les bandes de papier qui reçoivent le tabac et forment le boudin, sont délivrées sous forme de bobines, et présentent donc une longueur finie. Ainsi le segment final de chaque bande de papier doit être relié au segment initial de la bande suivante à chaque changement de bobine.In machines for manufacturing cigarettes or filters operating continuously, the paper strips which receive the tobacco and form the rod, are delivered in the form of reels, and therefore have a finite length. Thus the final segment of each strip of paper must be linked to the initial segment of the following strip each time the reel is changed.

On sait qu'il est avantageux d'effectuer cette liaison par interpénétration de matière plutôt que par collage. Les deux segments final et initial des deux bandes, qui doivent être solidarisés, doivent être placés dans des positions relatives de recouvrement mutuel et retenus dans ces positions de telle manière que la déformation contrôlée nécessaire pour assurer l'interpénétration s'effectue correctement.We know that it is advantageous to make this connection by interpenetration of material rather than by gluing. The final and initial two segments of the two bands, which must be joined, must be placed in relative positions of mutual overlap and retained in these positions in such a way that the controlled deformation necessary to ensure interpenetration takes place correctly.

En général, ces opérations sont effectuées par des moyens incorporés à la machine de fabrication et ces moyens comportent des dispositifs dont la plupart sont compliqués, lourds et coûteux, sans toutefois assurer une automatisation complète du remplacement d'une bobine en fin de course par une nouvelle bobine pleine.In general, these operations are carried out by means incorporated in the manufacturing machine and these means comprise devices, most of which are complicated, heavy and costly, without however ensuring complete automation of the replacement of a reel at the end of its stroke by a new full reel.

Selon le document GB-2 17 4371, les deux segments sont maintenus l'un au-dessus de l'autre par des dispositifs superposés, puis des zones de liaison appartenant à chacun des segments sont comprimées, après quoi les segments sont coupés respectivement en arrière et en avant des zones de liaison.According to GB-2 17 4371, the two segments are held one above the other by superimposed devices, then connecting zones belonging to each of the segments are compressed, after which the segments are respectively cut into behind and in front of the connection zones.

Selon le document FR-1 287 020, le segment initial de la nouvelle bande est maintenu au moment de la liaison, en coïncidence avec le segment final de l'ancienne bande par une paire de rouleaux entre lesquels les deux bandes sont conduites, et les organes de pression sont eux-mêmes deux galets tournant sur leurs axes et entre lesquels passent les zones de liaison des segments.According to document FR-1 287 020, the segment initial of the new strip is maintained at the time of the connection, coinciding with the final segment of the old strip by a pair of rollers between which the two strips are driven, and the pressure members are themselves two rollers rotating on their axes and between which pass the connecting zones of the segments.

Selon le document GB-1 086 065, le segment initial de la nouvelle bande est fixé à un galet, au-dessus du segment final de l'ancienne bande, puis un poinçon est abaissé contre une surface d'embase de manière que des zones de liaion appartenant aux deux segments final et initial de l'ancienne et de la nouvelle bande soient comprimées et liées par interpénétration de matière. Ensuite, les parties arrière et avant des segments final et initial sont sectionnées. La disposition des lames de sectionnement est telle que le risque d'endommagement des parties de segments qui ne doivent pas être coupées subsiste.According to GB-1 086 065, the initial segment of the new band is fixed to a roller, above the final segment of the old band, then a punch is lowered against a base surface so that zones of liaion belonging to the final and initial two segments of the old and the new band are compressed and linked by interpenetration of matter. Then, the rear and front parts of the final and initial segments are cut. The arrangement of the cutting blades is such that the risk of damage to the segment parts which must not be cut remains.

On connaît encore, par le document US-2 724 426, un procédé et une machine capables d'effectuer des liaisons entre des sangles d'emballage qui se déroulent de bobines successives. La liaison est effectuée par soudage. Dans ce cas, le segment final de l'ancienne bande et le segment initial de la nouvelle bande sont sectionnés respectivement en arrière et en avant de la zone de liaison avant que ces zones de liaison soient amenées en superposition et cette dernière opération est effectuée après coup, ce qui exige un appareillage compliqué.Also known from document US-2,724,426 is a method and a machine capable of making connections between packaging straps which take place from successive reels. The connection is made by welding. In this case, the final segment of the old strip and the initial segment of the new strip are sectioned respectively behind and in front of the connection zone before these connection zones are brought into superposition and this last operation is carried out after suddenly, which requires complicated apparatus.

Enfin, le document GB-A-2189226 décrit un procédé d'assemblage bout-à-bout de bandes selon le préambule de la revendication 1.Finally, document GB-A-2189226 describes a method of end-to-end assembly of strips according to the preamble of claim 1.

Ce dispositif ne fait pas partie de l'invention et ne sera pas décrit ici. La liaison entre un segment final 5 (fig. 2) de la bande 8 enroulée sur la première bobine et un segment initial 6 de la bande 11 portée par la deuxième bobine, a lieu dans un dispositif de liaison désigné de façon générale par 7 et qui sera décrit plus en détail plus loin. A la fig. 1, la bande 8 se déroule de la première bobine 3, passe sur un galet 9 et est conduite ensuite vers une machine de fabrication de cigarettes. Avant la phase finale du déroulement de la bobine 3, donc avant que toute la bande ait quitté le mandrin 1 et se soit déroulée, on active par des moyens qui ne sont pas représentés, le déroulement de cette bobine 3, de façon à créer une réserve de papier 10 en aval du dispositif de liaison 7. Ensuite, il est possible de bloquer la bobine 3 pour effectuer la liaison. Une dernière longueur de bande, qui forme le segment final 5, se trouve alors partiellement dans le dispositif de liaison et un coupeur 29 est mis en action de façon à couper ce segment final selon une ligne située à un endroit prédéterminé. Ensuite, un transporteur 12 auquel a été fixé le segment initial 6 de la bande de papier 11 enroulée sur la bobine 4 est déplacé d'une position initiale représentée à la fig. 1 à une position de liaison représentée à la fig. 2, de sorte que le segment initial 6 de la bande 11 vient se placer en regard du segment final 5 de la bande 8 et se superpose à lui. Des zones de liaison que l'on définira plus loin et qui appartiennent à ces deux segments sont alors exactement superposées dans le dispositif de liaison. Le segment 6 est alors fixé par rapport à l'embase du dispositif de liaison. Le transporteur 12 est ramené dans sa position initiale et les moyens de liaison sont mis en oeuvre de façon à réaliser la liaison des deux segments final et initial par interpénétration, comme le montre schématiquement la fig. 3. Pendant cette opération, la partie de bande 8 mise en réserve fournit l'alimentation nécessaire à la machine de cigarettes. Une fois que la liaison est réalisée, la nouvelle bobine 4 peut être entraînée en rotation ou plus exactement libérée et une bande continue se déplace en direction de la machine de fabrication.Figs. 1, 2 and 3 show the essential elements of the machine and illustrate the implementation of the process. These figures show a mandrel 1 for supporting a first coil 3 on which is wound a strip 8 and a mandrel 2 for supporting a second coil 4 on which is wound a strip 11. These mandrels are discs located at same level, with parallel axes and sufficient spacing so that, when the first coil 3 is about to run out, the second coil 4 can be mounted on the mandrel 2. The reel support mandrels are associated with a supply device which can be arranged in different ways depending on whether the reels are put in place and prepared for unwinding by hand or in a mechanized manner. This device is not part of the invention and will not be described here. The connection between a final segment 5 (fig. 2) of the strip 8 wound on the first reel and an initial segment 6 of the strip 11 carried by the second reel takes place in a connecting device generally designated by 7 and which will be described in more detail later. In fig. 1, the strip 8 is unwound from the first reel 3, passes over a roller 9 and is then led to a machine for manufacturing cigarettes. Before the final phase of the unwinding of the reel 3, therefore before the entire strip has left the mandrel 1 and has taken place, the unwinding of this reel 3 is activated by means which are not shown, so as to create a reserve of paper 10 downstream of the connecting device 7. Then, it is possible to block the reel 3 to make the connection. A last length of strip, which forms the final segment 5, is then partially in the connecting device and a cutter 29 is actuated so as to cut this final segment along a line located at a predetermined location. Next, a conveyor 12 to which the initial segment 6 of the paper strip 11 wound on the reel 4 has been fixed is moved from an initial position shown in FIG. 1 at a connection position shown in FIG. 2, so that the initial segment 6 of the strip 11 is placed opposite the final segment 5 of the strip 8 and is superimposed on it. Connection zones which will be defined later and which belong to these two segments are then exactly superimposed in the connecting device. The segment 6 is then fixed relative to the base of the connecting device. The conveyor 12 is returned to its initial position and the connection means are used so as to link the two final and initial segments by interpenetration, as shown diagrammatically in FIG. 3. During this operation, the strip portion 8 set aside provides the necessary power for the cigarette machine. Once the connection is made, the new coil 4 can be rotated or more exactly released and a continuous strip moves in the direction of the manufacturing machine.

Les fig. 4 à 8 montrent différents aspects du dispositif de liaison 7. Un support à paroi verticale 13 (fig. 7 et 8) porte une console générale 14 supportant elle-même les éléments essentiels du dispositif de liaison. La console 14 porte une plaque 19 et est agencée avec une embase équipée de trois suceurs fixes 16, 17 et 18. La plaque 19 (voir fig. 4, 5 et 6) située au centre et à fleur de la surface supérieure horizontale 14a de la console 14 est conçue de façon à coopérer avec un poinçon 20 situé au-dessus d'elle et dont le fonctionnement sera décrit plus loin. Le suceur 16 est aménagé dans l'embase 14a en avant de l'élément d'appui 19. Il comporte un collecteur horizontal 16a communiquant par deux rangées de cinq conduits 16b avec la surface 14a et un raccord 21 qui est relié par une tubulure 22 à une source de vide. Les orifices des conduits 16b débouchent dans la surface 14a sous forme de deux rangées parallèles étalées sur une largeur correspondant à la largeur L des bandes 8 et 11 portées par les mandrins 1 et 2.Figs. 4 to 8 show different aspects of the connection device 7. A vertical wall support 13 (fig. 7 and 8) carries a general console 14 itself supporting the essential elements of the connection device. The console 14 carries a plate 19 and is arranged with a base fitted with three fixed nozzles 16, 17 and 18. The plate 19 (see fig. 4, 5 and 6) located in the center and flush with the horizontal upper surface 14a of the console 14 is designed so as to cooperate with a punch 20 located above it and the operation of which will be described later. The squeegee 16 is arranged in the base 14a in front of the support element 19. It comprises a horizontal collector 16a communicating by two rows of five conduits 16b with the surface 14a and a connector 21 which is connected by a tube 22 to a vacuum source. The orifices of the conduits 16b open into the surface 14a in the form of two parallel rows spread over a width corresponding to the width L of the strips 8 and 11 carried by the mandrels 1 and 2.

Les suceurs 17 et 18 ont une constitution semblable à celle du suceur 16 et comportent chacun deux rangées d'orifices 17b et 18b disposées côte à côte en arrière de l'élément d'appui 19, une fente 23 étant aménagée entre ces deux suceurs.The squeegees 17 and 18 have a constitution similar to that of the squeegee 16 and each comprise two rows of orifices 17b and 18b arranged side by side behind the support element 19, a slot 23 being arranged between these two squeegees.

Enfin, en arrière des suceurs 17 et 18, on trouve encore un autre suceur 24 qui comporte un corps cylindrique fixé à la console 14. Ce corps cylindrique est muni de plusieurs rangées de conduits 24b et comporte un collecteur central 24a. Ce dernier est raccordé par un raccord 25 à une tubulure d'aspiration 26. Le suceur 24 est placé à une certaine distance en arrière de la partie de l'embase 14 qui porte les suceurs 17 et 18. Une fente 27 dont la fonction sera décrite plus loin est prévue entre les suceurs 24 et 18. On remarque que le corps cylindrique du suceur 24 est tangent au plan horizontal de la surface 14a et en particulier à la face supérieure plane de l'élément d'appui 19. Au-dessus de ces moyens de fixation et d'appui, le dispositif de liaison 7 comporte un tendeur à galet 28, un coupeur 29, et un poinçon 30. Le tendeur 28 consiste essentiellement en un galet cylindrique 59 porté par un étrier 60 fixé à la tige 21 d'un vérin 32. Les tubulures 33 et 34 de ce vérin sont reliées à un dispositif de commande de type pneumatique ou hydraulique. Au moment voulu, le galet 59 sera abaissé en direction des moyens de fixation comme on le verra plus loin. Le coupeur 29 est également représenté à la fig. 7. Il comporte une lame 35 fixée à l'extrémité inférieure de la tige 38 d'un vérin 39. Ce coupeur peut être commandé de façon à se déplacer de haut en bas ou de bas en haut. Comme on le voit à la fig. 4, lors de son déplacement vers le bas, la lame 35 pénètre dans la fente 23 et assure la découpe de la bande 8 selon une ligne perpendiculaire à la direction de déplacement du papier. Au moment de cette opération, la partie de cette bande qui se trouve au-dessus des suceurs 17 et 18 est aspirée par ces suceurs et, de ce fait, plaquée contre la surface plane du dispositif. De plus, un jet d'air propulsé par un souffleur 36 est dirigé sur la bande.Finally, behind the nozzle 17 and 18, there is yet another nozzle 24 which comprises a cylindrical body fixed to the console 14. This cylindrical body is provided with several rows of conduits 24b and comprises a central manifold 24a. The latter is connected by a connector 25 to a suction tube 26. The nozzle 24 is placed at a certain distance behind the part of the base 14 which carries the nozzles 17 and 18. A slot 27 whose function will be described below is provided between the squeegees 24 and 18. Note that the cylindrical body of the squeegee 24 is tangent to the horizontal plane of the surface 14a and in particular to the flat upper face of the support element 19. Above of these fixing and support means, the connecting device 7 comprises a roller tensioner 28, a cutter 29, and a punch 30. The tensioner 28 essentially consists of a cylindrical roller 59 carried by a stirrup 60 fixed to the rod 21 of a jack 32. The pipes 33 and 34 of this jack are connected to a pneumatic or hydraulic type control device. At the desired time, the roller 59 will be lowered towards the fastening means as will be seen below. The cutter 29 is also shown in FIG. 7. It comprises a blade 35 fixed to the lower end of the rod 38 of a jack 39. This cutter can be controlled so as to move from top to bottom or from bottom to top. As seen in fig. 4, during its downward movement, the blade 35 penetrates into the slot 23 and ensures the cutting of the strip 8 according to a line perpendicular to the direction of movement of the paper. At the time of this operation, the part of this strip which is located above the nozzles 17 and 18 is sucked in by these nozzles and, therefore, pressed against the flat surface of the device. In addition, an air jet propelled by a blower 36 is directed onto the strip.

Le poinçon 30 est également visible en élévation de profil à la fig. 8. Sur la console 14 sont fixés d'une part un vérin 41 et d'autre part une coulisse 42 capable de guider verticalement le corps de poinçon 20 qui est fixé à la tige 43 du vérin 41. La forme du corps de poinçon 20 est celle d'un parallèlépipède rectangle avec une face inférieure 44 qui s'étend selon un plan et qui est pourvue d'un relief formé d'un réseau de pointes 45. Les tubulures 46 et 47 assurent la commande du vérin 41.The punch 30 is also visible in side elevation in FIG. 8. On the console 14 are fixed on the one hand a jack 41 and on the other hand a slide 42 capable of vertically guiding the punch body 20 which is fixed to the rod 43 of the jack 41. The shape of the punch body 20 is that of a rectangular parallelepiped with a lower face 44 which extends along a plane and which is provided with a relief formed by a network of points 45. The pipes 46 and 47 provide control of the jack 41.

On va décrire encore le transporteur 12 et des moyens qui permettent de fixer le segment initial 6 de la bande 11 à ce transporteur. L'élément transporteur 12 (fig. 6) est une plaque équipée de conduits de suceur 48 et munie d'une fente 49. Cette plaque 12 est portée par un organe mobile (non représenté) de façon à pouvoir se déplacer de la position représentée à la fig. 6 qui est la position de liaison à la position initiale représentée aux fig. 1 et 3 puis en sens inverse de celle-ci à la position de liaison. Dans sa position initiale, la plaque 12 du transporteur se trouve au voisinage de la bobine 4 (v. fig. 1 et 3), exactement en regard d'un élément de positionnement 50 qui est équipé d'un coupeur 51 actionné par le vérin 52.We will still describe the transporter 12 and means which allow the initial segment 6 of the strip 11 to be fixed to this transporter. The conveyor element 12 (fig. 6) is a plate fitted with squeegee conduits 48 and provided with a slot 49. This plate 12 is carried by a movable member (not shown) so as to be able to move from the position shown in fig. 6 which is the position of connection to the initial position shown in FIGS. 1 and 3 then in the opposite direction to the connection position. In its initial position, the plate 12 of the conveyor is located in the vicinity of the coil 4 (see fig. 1 and 3), exactly opposite a positioning element 50 which is equipped with a cutter 51 actuated by the jack. 52.

Lorsque la bande 8 enroulée sur la bobine 3 est pratiquement à épuisement et que la réserve 10 a été formée comme on l'a dit au début, le déroulement de cette bobine est interrompu, et par mise en action des suceurs 16, 17 et 24, le segment final 5 de la bande 8 est fixé à l'embase. A ce moment, l'extrémité 6 de la bande 11 est détachée de la bobine 4 et placée sur l'élément 50.When the strip 8 wound on the reel 3 is practically exhausted and the reserve 10 has was formed as we said at the beginning, the unwinding of this coil is interrupted, and by activating the squeegees 16, 17 and 24, the final segment 5 of the strip 8 is fixed to the base. At this moment, the end 6 of the strip 11 is detached from the coil 4 and placed on the element 50.

Le dispositif suceur 48 associé au transporteur 12 lie alors la partie du segment 6 qui se trouve sur l'élément 50 au transporteur. Le coupeur 51 est actionné et le transporteur 12 est déplacé vers la position de liaison.The suction device 48 associated with the transporter 12 then links the part of the segment 6 which is located on the element 50 to the transporter. The cutter 51 is actuated and the conveyor 12 is moved to the connection position.

Le bras transporteur 12 décrit alors un mouvement qui l'amène, de la position initiale représentée à la fig. 1 à la position de liaison représentée à la fig. 2. Cette position de liaison est déterminée d'une façon précise, afin que, comme on le voit à la fig. 6, la ligne de coupe du segment initial 6 se trouve exactement jointive avec le bord antérieur de l'élément d'appui 19, c.à.d. immédiatement en-dessous du bord antérieur de la surface 44 garnie des pointes 45 du corps de poinçon 20 (voir fig. 3). Lorsque cette position est atteinte, le suceur 18 est excité à nouveau, le dispositif tendeur 28 est amené en position inférieure, de sorte que le galet 59 prend la position de la fig. 6. D'autre part, le suceur 48 est mis hors service, et le transporteur 12 libère le segment 6, puis s'écarte de sa position de liaison. Le dispositif de liaison est alors dans la position de la fig. 3. Le vérin 41 est actionné et le corps de poinçon 20 vient presser les deux segments 5 et 6 superposés entre sa surface inférieure 44 et la surface supérieure de l'élément d'appui 19. Au cours de cette opération, il se produit une interpénétration des papiers des deux segments selon des zones correspondantes qui constituent les zones de liaison de la bande 8 avec la bande 11.The conveyor arm 12 then describes a movement which brings it from the initial position shown in FIG. 1 at the connection position shown in FIG. 2. This connection position is determined in a precise manner, so that, as seen in FIG. 6, the line of cut of the initial segment 6 is exactly contiguous with the front edge of the support element 19, i.e. immediately below the front edge of the surface 44 filled with the points 45 of the punch body 20 (see fig. 3). When this position is reached, the squeegee 18 is excited again, the tensioning device 28 is brought into the lower position, so that the roller 59 takes the position of FIG. 6. On the other hand, the squeegee 48 is put out of service, and the transporter 12 releases the segment 6, then departs from its connection position. The connecting device is then in the position of FIG. 3. The jack 41 is actuated and the punch body 20 presses the two segments 5 and 6 superimposed between its lower surface 44 and the upper surface of the support element 19. During this operation, a interpenetration of the papers of the two segments according to corresponding zones which constitute the strip 8 connecting zones with strip 11.

Une fois que cette liaison est effectuée, le poinçon 20 peut être relevé et le tirage de la bande de papier peut reprendre.Once this connection is made, the punch 20 can be raised and the drawing of the paper strip can resume.

Les essais ont montré que les moyens décrits permettaient d'établir une liaison entre des bandes successives de papier du type utilisé dans la fabrication de cigarettes. Cette liaison est suffisamment résistante pour permettre la formation d'un boudin continu et le sectionnement ultérieur de ce boudin en éléments constituant des cigarettes. La liaison est réalisée de manière automatique et sans utiliser de colle.Tests have shown that the means described make it possible to establish a connection between successive strips of paper of the type used in the manufacture of cigarettes. This connection is strong enough to allow the formation of a continuous rod and the subsequent sectioning of this rod into elements constituting cigarettes. The connection is made automatically and without using glue.

La machine décrite, ou en tout cas certains de ses éléments peuvent être réalisés et fonctionner selon différentes modalités, tout en accomplissant les mêmes fonctions ou des fonctions semblables, selon que l'on désire un fonctionnement partiellement ou entièrement automatique.The machine described, or in any case some of its elements, can be produced and operate in different ways, while performing the same or similar functions, depending on whether a partially or fully automatic operation is desired.

Le transporteur 12 pourrait être déplacé par une courroie sur une coulisse de guidage ou en pivotement autour d'un axe. Comme on l'a dit, les moyens de déplacement seront agencés de manière que les déplacements du transporteur soient d'une grande précision.The conveyor 12 could be moved by a belt on a guide slide or by pivoting about an axis. As said, the displacement means will be arranged so that the movements of the conveyor are of high precision.

Le suceur d'écartement 24 pourrait, le cas échéant, être mobile en rotation autour de son axe et commandé de manière à tourner d'un certain angle au moment où la partie coupée du segment 6 doit libérer le suceur 18.The spacer nozzle 24 could, if necessary, be movable in rotation about its axis and controlled so as to rotate by a certain angle when the cut part of segment 6 must release the nozzle 18.

Enfin les commandes des vérins et les suceurs seront reliés à un dispositif électronique susceptible d'être programmé et contrôlé de manière que chaque action s'enclenche au moment voulu et que son exécution correcte soit vérifiée et confirmée. Les détecteurs nécessaires seront prévus pour cela aux endroits voulus.Finally, the actuators of the jacks and the squeegees will be connected to an electronic device capable of being programmed and controlled so that each action is triggered at the desired moment and that its execution be checked and confirmed. The necessary detectors will be provided for this in the desired locations.

De manière générale, bien que l'on ait représenté et décrit comme moyen de fixation des suceurs et comme organe de déplacement des vérins, il est clair que tout autre moyen de fixation ou de déplacement peut aussi être prévu. Cependant, l'emploi de suceurs comme moyen de fixation simplifie l'agencement de la console 14. En effet, l'ensemble des dispositifs suceurs peut être placé sous la surface d'embase, donc en-dessous des bandes à relier, ce qui ménage la place nécessaire pour le déplacement du transporteur amenant le segment 6 de la bande 11 au dessus du segment 5 de la bande 8.In general, although it has been shown and described as a means of fixing the squeegees and as a member for moving the jacks, it is clear that any other means of fixing or moving can also be provided. However, the use of squeegees as a fixing means simplifies the arrangement of the console 14. In fact, all of the sucking devices can be placed under the base surface, therefore below the bands to be connected, which saves the space necessary for the movement of the conveyor bringing the segment 6 of the band 11 above the segment 5 of the band 8.
