Abstract

The transfer device for a tobacco rod is an improvement made to a cigarette machine; the entrainment of the tobacco rod (31) is more uniform when the web of paper (42) which is to surround the tobacco rod circulates in parallel with the porous belt (21) over a certain distance; moreover, by applying a certain compression to the tobacco rod before the latter penetrates into a guiding groove arranged under the guiding shoe (45), the rod may be made into circular shape by reducing the friction of the tobacco against the walls of the groove, which reduces the heating-up of the tobacco and the wear of the groove. <IMAGE>

Description

La présente invention concerne une amélioration d'un dispositif de transfert d'un boudin de tabac, disposé entre la poutre destinée à former et transporter ledit boudin de tabac et la partie de machine où une bande de papier sera disposée autour de ce boudin afin de former le cylindre continu qui sera ensuite découpé en cigarettes.The present invention relates to an improvement of a device for transferring a tobacco rod, placed between the beam intended to form and transport said tobacco rod and the part of the machine where a strip of paper will be placed around this rod in order to form the continuous cylinder which will then be cut into cigarettes.

La partie de machine à cigarettes chargée de former et de transporter le boudin de tabac, par aspiration sur une courroie poreuse mobile, est connue; on en trouve en particulier une description dans les demandes de brevets CH 3013/88-8 et CH 2121/90-7. Il en est de même de celle où le boudin est entouré d'une bande de papier afin de former un cylindre circulaire continu. Le dispositif de transfert, qui est la partie de machine située entre les deux parties précédentes, et qui est chargé d'assurer la transition ou le transfert du boudin entre la courroie poreuse et la bande de papier transportée par une courroie continue disposée en face de la précédente, ainsi que de la formation dudit boudin de tabac en un cylindre de section circulaire, est celui qui nous intéresse dans le cadre de la présente demande.The part of the cigarette machine responsible for forming and transporting the tobacco rod, by suction on a porous moving belt, is known; a description is found in particular in patent applications CH 3013 / 88-8 and CH 2121 / 90-7. The same is true for that where the rod is surrounded by a strip of paper in order to form a continuous circular cylinder. The transfer device, which is the part of the machine located between the two preceding parts, and which is responsible for ensuring the transition or the transfer of the rod between the porous belt and the strip of paper transported by a continuous belt arranged opposite the previous one, as well as the formation of said tobacco rod in a cylinder of circular section, is the one which interests us within the framework of the present application.

Selon l'art antérieur, cette partie de la machine comprend une poulie de renvoi de la courroie poreuse, généralement une poulie d'entraînement, dont le diamètre est relativement important. Vu que la poutre est sous dépression par rapport à l'atmosphère ambiante afin d'aspirer le tabac sur la courroie poreuse, il s'agit d'assurer une certaine étanchéité de son extrémité, en particulier à l'endroit où ladite poulie de renvoi est disposée. Pour ceci, il est nécessaire de prévoir une pièce mécanique en forme de sabot, dont une partie en arc de cercle concave vient se plaquer à faible distance de la courroie poreuse disposée sur la poulie; afin de conserver une distance uniforme entre ce sabot et la courroie, ce sabot est fixé de manière réglable sur ladite poutre, en aval de la poulie de renvoi.According to the prior art, this part of the machine comprises a pulley for returning the porous belt, generally a drive pulley, the diameter of which is relatively large. Since the beam is under vacuum with respect to the ambient atmosphere in order to suck the tobacco on the porous belt, it is a question of ensuring a certain tightness of its end, in particular at the place where said pulley of return is willing. For this, it is necessary to provide a mechanical part in the shape of a shoe, one of which part in a concave arc is placed a short distance from the porous belt disposed on the pulley; in order to maintain a uniform distance between this shoe and the belt, this shoe is fixed in an adjustable manner on said beam, downstream of the return pulley.

Légèrement en amont de l'extrémité de la poutre, sur la partie supérieure du bâti de la machine faisant face à la courroie poreuse et au-dessous de ladite courroie, une autre poulie est chargée de guider une autre courroie transportant le ruban de papier qui viendra entourer ultérieurement le boudin de tabac. Le ruban de papier et la courroie poreuse circulent sur une certaine distance se rapprochant l'une de l'autre de manière que le ruban de papier commence à entraîner le boudin à peu près à l'endroit où celui-ci quitte la courroie poreuse.Slightly upstream of the end of the beam, on the upper part of the machine frame facing the porous belt and below the said belt, another pulley is responsible for guiding another belt carrying the paper tape which will later surround the rod of tobacco. The paper tape and the porous belt circulate a certain distance approaching each other so that the paper tape begins to drive the flange about where it leaves the porous belt.

Lorsque ledit boudin arrive au droit de l'axe de la poulie de renvoi de la courroie poreuse, il en est détaché et pénètre sous le sabot assurant l'étanchéité, étant guidé par une rainure longitudinale de section transversale semi-carrée disposée dans la face inférieure du sabot. Lorsqu'il quitte ce sabot, le boudin est donc de forme approximativement carrée, ses côtés supérieur et latéraux étant formés par les côtés de la rainure de guidage longitudinale alors que son côté inférieur s'appuie sur le ruban de papier soutenu par sa courroie de transport.When said flange arrives at the axis of the pulley returning the porous belt, it is detached from it and penetrates under the shoe ensuring the seal, being guided by a longitudinal groove of semi-square cross section arranged in the face bottom of the hoof. When it leaves this shoe, the flange is therefore approximately square in shape, its upper and lateral sides being formed by the sides of the longitudinal guide groove while its lower side rests on the paper tape supported by its strap. transport.

Après avoir passé le sabot décrit précédemment, le boudin de tabac passe sous un doigt de guidage, dont la face inférieure comporte également une rainure longitudinale, et qui est fixé et ajustable sur le banc de la machine; le ruban de papier vient s'enrouler autour du boudin de tabac, le long de ce doigt de guidage, entraînant par la suite ledit boudin de tabac.After passing the shoe described above, the tobacco rod goes under a guide finger, the underside of which also has a longitudinal groove, and which is fixed and adjustable on the machine bench; the paper ribbon is wound around the tobacco rod, along this guide finger, subsequently driving said tobacco rod.

Comme il a été dit plus haut, le boudin de tabac est de section approximativement carrée lorsqu'il quitte le sabot; après avoir passé le doigt de guidage et être complètement enroulé dans le ruban de papier de cigarette, sa section est circulaire, la transition entre ces deux formes se produisant sous le doigt de guidage; la rainure longitudinale de la face inférieure de cet élément passe de façon continue d'une section transversale semi-carrée à une section en un demi-cercle et forme ainsi la partie supérieure du boudin, alors que la forme circulaire de la partie inférieure du boudin est donnée au moment où le ruban de papier est appliqué contre le boudin. Il est absolument nécessaire, pour une bonne formation du boudin, que les deux rainures longitudinales successives de guidage du sabot et du doigt de guidage soient parfaitement alignées.As mentioned above, the tobacco rod is of approximately square section when it leaves the hoof; after passing the guide finger and being completely wound in the strip of cigarette paper, its section is circular, the transition between these two forms occurring under the guide finger; the longitudinal groove of the underside of this element passes continuously from a semi-square cross section to a section in a semicircle and thus forms the upper part of the rod, while the circular shape of the lower part of the rod is given when the paper tape is applied against the sausage. It is absolutely necessary, for a good formation of the flange, that the two successive longitudinal grooves for guiding the shoe and the guide finger are perfectly aligned.

Ce dispositif selon l'art antérieur comporte de nombreux inconvénients, en particulier celui d'endommager le tabac à l'intérieur du boudin. En effet, lorsqu'il quitte la courroie poreuse, il pénètre dans la rainure de guidage du sabot, les faces supérieure et latérales du boudin frottant fortement contre la rainure de guidage; par la suite, lorsqu'il passe par la rainure de guidage du doigt de guidage, le boudin passe d'une section carrée à une section circulaire par compression d'une partie importante de son pourtour. Le frottement des brins de tabac contre les parois des deux rainures de guidage provoque un échauffement du boudin, conduisant à un desséchement et à la fragilisation des brins de tabac. Subsidiairement, le frottement du tabac contre le sabot et le doigt de guidage entraîne une forte usure de ces éléments, nécessitant leur remplacement fréquent. D'autre part, le fait que la partie supérieure du boudin soit freinée par le frottement contre les rainures alors que la partie inférieure est entraînée par le ruban de papier provoque un effet de cisaillement longitudinal du boudin, endommageant les brins de tabac et créant des irrégularités de densité longitudinale de tabac à l'intérieur du boudin, pouvant aller jusqu'à la déchirure du boudin, ainsi que des variations de la distance séparant les régions à plus forte densité de tabac qui constitueront les extrémités de la cigarette terminée. Cet effet est encore accentué du fait que la transition entre le mouvement d'entraînement de la partie supérieure du boudin par la courroie poreuse et le mouvement d'entraînement de la partie inférieure du boudin par la bande de papier sur sa courroie porteuse se fait sur une très courte distance, voire sur un seul point. Un autre inconvénient du dispositif selon l'art antérieur réside dans le fait que la rainure de guidage de la partie supérieure du boudin se trouve sur deux éléments distincts, le sabot et le doigt de guidage, disposés chacun sur un élément séparé de la machine, et qu'il est nécessaire de soigneusement aligner l'un à la suite de l'autre.This device according to the prior art has many drawbacks, in particular that of damaging the tobacco inside the tube. Indeed, when it leaves the porous belt, it enters the guide groove of the shoe, the upper and lateral faces of the flange rubbing strongly against the guide groove; thereafter, when it passes through the guide groove of the guide finger, the rod changes from a square section to a circular section by compression of a large part of its periphery. The friction of the tobacco strands against the walls of the two guide grooves causes the rod to heat up, leading to drying and embrittlement of the tobacco strands. In the alternative, the friction of the tobacco against the hoof and the guide finger causes heavy wear of these elements, requiring their frequent replacement. On the other hand, the fact that the upper part of the flange is braked by the friction against the grooves while the lower part is entrained by the paper tape causes a longitudinal shearing effect of the rod, damaging the tobacco strands and creating irregularities of longitudinal density of tobacco inside the rod, which can go as far as tearing the rod, as well as variations in the distance separating the regions with the highest density of tobacco which will constitute the ends of the finished cigarette. This effect is further accentuated by the fact that the transition between the driving movement of the upper part of the sausage by the porous belt and the driving movement of the lower part of the sausage by the strip of paper on its carrying belt takes place on a very short distance, even on a single point. Another drawback of the device according to the prior art lies in the fact that the guide groove of the upper part of the flange is located on two separate elements, the shoe and the guide finger, each arranged on a separate element of the machine, and that it is necessary to carefully align one after the other.

Le dispositif de transfert selon l'invention, ayant les caractéristiques mentionnées dans les revendications, se propose de remédier à ces inconvénients en assurant un meilleur entraînement, un meilleur guidage et une meilleure formation du boudin, en évitant l'échauffement du tabac, tout en simplifiant de façon substantielle les réglages nécessaires à un alignement correct des éléments de guidage.The transfer device according to the invention, having the characteristics mentioned in the claims, proposes to remedy these drawbacks by ensuring better training, better guidance and better formation of the rod, by avoiding the heating of the tobacco, while substantially simplifying the adjustments necessary for correct alignment of the guide elements.

Le fonctionnement du dispositif selon l'invention est plus particulièrement compréhensible à partir du dessin en annexe avec les figures où:

  • la figure 1 représente une machine à cigarettes sur laquelle est monté un dispositif selon l'art antérieur,
  • la figure 2 représente une partie aval à plus grande échelle d'une machine à cigarettes, sur laquelle est monté un dispositif selon une forme d'exécution préférentielle de l'invention,
  • la figure 3 représente trois vues d'une forme d'exécution préférentielle d'un doigt de guidage selon l'invention.
The operation of the device according to the invention is more particularly understandable from the attached drawing with the figures where:
  • FIG. 1 represents a cigarette machine on which a device according to the prior art is mounted,
  • Figure 2 shows a downstream part to larger scale of a cigarette machine, on which is mounted a device according to a preferred embodiment of the invention,
  • FIG. 3 represents three views of a preferred embodiment of a guide finger according to the invention.

Sur la figure 1, on a une machine à cigarettes 1 sur laquelle est montée la poutre 2 selon l'art antérieur. La machine à cigarettes comprend en particulier les éléments suivants: un réservoir 10 ou stock intermédiaire de tabac 3, ainsi qu'un dispositif de compression-écrêtage 11. La poutre 2 est constituée d'un bâti métallique 20, de forme généralement parallélépipédique allongée et dont la face inférieure est ouverte afin que la courroie poreuse mobile 21 soit accessible pour la confection du boudin de tabac 30. La courroie 21 est une courroie sans fin, entraînée par les poulies 22 et 22a, de manière à se déplacer selon le sens indiqué par les flèches; les poulies 22b ne servent que de poulies de renvoi ou à maintenir la courroie 21 tendue. Le dispositif d'entraînement des poulies 22 et 22a est conventionnel et n'est pas représenté. Un dispositif d'aspiration, non représenté, débouche à l'intérieur du bâti métallique 20 de la poutre 2, sur la face supérieure du brin inférieur de la courroie poreuse 21. Ainsi, lorsque le dispositif d'aspiration fonctionne et que la courroie 21 est entraînée par les poulies 22 et 22a, le tabac 3 se trouvant dans le réservoir 10 est aspiré par la courroie poreuse 21 et s'agglomère sous la courroie afin de former le boudin 30, lequel, après passage par le dispositif de compression-écrêtage 11, puis à travers les guides latéraux 12, deviendra le boudin 31 que l'on trouve vers l'extrémité aval de la poutre 2. A cet endroit, le boudin 31 est de section approximativement carrée, sa face supérieure étant appliquée par aspiration contre la face inférieure de la courroie 21, ses deux côtés latéraux ayant été formés contre les guides latéraux 12 et sa face inférieure plane provenant du dispositif de compression-écrêtage 11. Le boudin 31 est entraîné par la courroie 21 jusqu'au droit de l'axe de la poulie 22 où l'aspiration dudit boudin contre la courroie cesse. Un sabot racleur 23 assure l'étanchéité de cette partie de la poutre 2, étant fixé de manière réglable à la poutre 2; la partie avant dudit sabot 23 est de forme concave et est disposée très près de la courroie 21 afin de détacher le boudin 31 de la courroie. Un dispositif d'application du papier de cigarette 4 est constitué d'un rouleau 40 placé légèrement en amont et sous la courroie poreuse 21 afin de guider une seconde courroie 41 que rejoint un ruban de papier 42 dévidé à partir d'une galette non représentée. La seconde courroie 41, respectivement le ruban de papier 42 sont entraînés à la même vitesse longitudinale que la courroie poreuse 21, respectivement le boudin 30. Le guidage de la seconde courroie 41 et du ruban de papier 42 est tel que ladite seconde courroie se rapproche de la courroie poreuse selon un certain angle de manière que le ruban de papier 42 sur la courroie 41 rejoigne la partie inférieure du boudin 31 environ au moment où ledit boudin quitte la courroie poreuse 21. Le boudin 31 est donc entraîné simultanément par les deux systèmes sur une très courte distance, voire seulement en un seul point.In Figure 1, there is a cigarette machine 1 on which is mounted the beam 2 according to the prior art. The cigarette machine comprises in particular the following elements: a reservoir 10 or intermediate tobacco stock 3, as well as a compression-clipping device 11. The beam 2 consists of a metal frame 20, of generally elongated parallelepiped shape and the underside of which is open so that the movable porous belt 21 is accessible for making the tobacco rod 30. The belt 21 is an endless belt, driven by the pulleys 22 and 22a, so as to move in the direction indicated by arrows; the pulleys 22b only serve as return pulleys or to keep the belt 21 tensioned. The pulley drive device 22 and 22a is conventional and is not shown. A suction device, not shown, opens inside the metal frame 20 of the beam 2, on the upper face of the lower strand of the porous belt 21. Thus, when the suction device operates and the belt 21 is driven by the pulleys 22 and 22a, the tobacco 3 located in the tank 10 is sucked up by the porous belt 21 and agglomerates under the belt in order to form the rod 30, which, after passing through the compression-clipping device 11, then through the lateral guides 12, will become the flange 31 which is found towards the downstream end of the beam 2. At this point, the flange 31 is of approximately square section, its face upper being applied by suction against the underside of the belt 21, its two lateral sides having been formed against the lateral guides 12 and its flat underside coming from the compression-clipping device 11. The flange 31 is driven by the belt 21 until 'In line with the axis of the pulley 22 where the suction of said strand against the belt ceases. A scraper shoe 23 seals this part of the beam 2, being fixed in an adjustable manner to the beam 2; the front part of said shoe 23 is of concave shape and is arranged very close to the belt 21 in order to detach the flange 31 from the belt. A device for applying cigarette paper 4 consists of a roller 40 placed slightly upstream and under the porous belt 21 in order to guide a second belt 41 joined by a strip of paper 42 unwound from a wafer not shown . The second belt 41, respectively the paper tape 42 are driven at the same longitudinal speed as the porous belt 21, respectively the flange 30. The guide of the second belt 41 and of the paper tape 42 is such that said second belt approaches porous belt at an angle so that the paper tape 42 on the belt 41 joins the lower part of the strand 31 about when said strand leaves the porous belt 21. The strand 31 is therefore driven simultaneously by the two systems over a very short distance, or even only at a single point.

Les faces inférieures du sabot 23 ainsi que d'un doigt de guidage 43, fixé de manière réglable au bâti de la machine à cigarettes 1 et disposé directement après le sabot 23, comprennent chacune une rainure longitudinale, la rainure aménagée sous le sabot 23 étant de forme semi-carrée, alors que celle aménagée sous le doigt de guidage 43 passe progressivement d'une forme semi-carrée à l'avant du doigt de guidage 43, à une forme en demi-cercle à proximité de l'arrière du doigt de guidage 43, où le boudin quitte ledit doigt de guidage, afin de donner une forme circulaire à la partie supérieure du boudin 31 lors de son passage sous ledit doigt de guidage. Le ruban de papier 42, qui est à plat lorsqu'il passe par-dessus de rouleau 40, est guidé ensuite par une flûte, non représentée, afin de s'enrouler autour du boudin 31 lors de son passage sous le doigt de guidage 43. A la sortie du doigt de guidage 43, le boudin 31 est entièrement entouré par le ruban de papier, ce qui a ainsi donné la forme circulaire à la partie inférieure dudit boudin.The undersides of the shoe 23 as well as of a guide finger 43, adjustably fixed to the frame of the cigarette machine 1 and disposed directly after the shoe 23, each include a longitudinal groove, the groove provided under the shoe 23 being of semi-square shape, while that arranged under the guide finger 43 progressively passes from a semi-square shape in front of the guide finger 43, in a semicircle shape near the rear of the guide finger 43, where the flange leaves said guide finger, in order to give a circular shape to the upper part of the flange 31 when it passes under said guide finger. The paper tape 42, which is flat when it passes over roller 40, is then guided by a flute, not shown, in order to wrap around the flange 31 during its passage under the guide finger 43 At the outlet of the guide finger 43, the flange 31 is entirely surrounded by the paper tape, which has thus given the circular shape to the lower part of said flange.

Le passage du boudin 31 d'une forme approximativement carrée à une forme circulaire se fait donc par compression des coins du carré, cette compression se faisant avec un frottement contre un élément statique, provoque un échauffement et une dégradation des brins de tabac. D'autre part, le boudin 31 étant entraîné tout d'abord par la courroie 21, puis par le ruban de papier 42, la transition entre ces deux modes d'entraînement se fait sur une très courte distance, voire en un point, ce mode de faire provoquant des discontinuités et des irrégularités de l'entraînement du boudin, causant un remplissage irrégulier du boudin et parfois même sa déchirure. En cas de déchirure du boudin, il est nécessaire d'arrêter la machine à cigarettes 1, diminuant ainsi son rendement.The passage of the rod 31 from an approximately square shape to a circular shape is therefore done by compression of the corners of the square, this compression being effected with friction against a static element, causes heating and degradation of the tobacco strands. On the other hand, the flange 31 being driven first by the belt 21, then by the paper tape 42, the transition between these two drive modes takes place over a very short distance, even at a point, this mode of doing causing discontinuities and irregularities in the training of the sausage, causing irregular filling of the sausage and sometimes even tearing. In the event of tearing of the tube, it is necessary to stop the cigarette machine 1, thereby reducing its efficiency.

Un autre inconvénient d'une machine selon l'art antérieur est qu'il est nécessaire, après que la poutre ait été ouverte, puis refermée, et avant de remettre en marche la machine, de contrôler et éventuellement corriger l'alignement de la courroie 21 et du sabot 23, par rapport au doigt de guidage 43. Cette opération, absolument nécessaire pour obtenir un boudin, respectivement des cigarettes de qualité, est compliquée et fastidieuse, vu que la poulie 22 et le sabot 23 se règlent sur la poutre 2, alors que le doigt de guidage 43 se règle sur le banc de la machine et que ces trois éléments indépendants doivent être parfaitement alignés.Another disadvantage of a machine according to the prior art is that it is necessary, after the beam has been opened, then closed, and before restarting the machine, to check and possibly correct the alignment of the belt 21 and shoe 23, relative to guide finger 43. This operation, absolutely necessary to obtain a sausage, respectively quality cigarettes, is complicated and tedious, since the pulley 22 and the shoe 23 are adjusted on the beam 2, while the guide finger 43 is adjusted on the machine bench and that these three independent elements must be perfectly aligned.

La figure 2 montre la partie aval de la poutre 2 équipée du dispositif selon l'invention, la partie amont étant semblable à celle décrite précédemment n'est pas représentée. Tout d'abord, le rouleau 40 sur lequel circule la seconde courroie 41 transportant le ruban de papier 42 est décalé vers l'amont, le ruban 42, après avoir passé sur le rouleau 40 étant amené progressivement en contact avec la face inférieure du boudin 31, qui est amené par une portion de courroie transporteuse 21 légèrement inclinée par rapport à la table de guidage 44. Un appui fixe de la courroie poreuse 21, disposé en amont de la poulie 22 et constitué préférentiellement d'une bague en matière céramique 22c capable de résister à l'abrasion causée par le passage de la courroie poreuse 21, modifie le trajet suivi par ladite courroie poreuse afin de la faire se déplacer parallèlement à la table de guidage 44, sur la portion de trajet située entre ladite bague 22c et le point situé au droit de l'axe de la poulie 22. Ainsi, le boudin 31 est progressivement serré entre la courroie 21 et la seconde courroie 41, respectivement le ruban de papier 42. Ces deux éléments se déplaçant à la même vitesse, un entraînement simultané dudit boudin par ces deux moyens a donc lieu sur une portion de la table de guidage 44, avant que l'entraînement par la courroie 2 ne cesse au droit de l'axe de la poulie 22. Cette manière de faire améliore de façon notable l'entraînement du boudin 31 et diminue sensiblement les risques de remplissage irrégulier ainsi que de déchirure du boudin 31. La distance séparant les deux courroies 21 et 41 lorsqu'elles circulent parallèlement l'une à l'autre, soit sur la portion de trajet située entre la bague fixe 22c et le point situé au droit de l'axe de la poulie 22, est telle que le boudin 31 subit une certaine compression dans le sens de la hauteur; cette compression ayant lieu entre deux éléments d'entraînement ne provoque pas d'échauffement du tabac.Figure 2 shows the downstream part of the beam 2 equipped with the device according to the invention, the upstream part being similar to that described above is not shown. First of all, the roller 40 on which the second belt 41 carrying the paper ribbon circulates is shifted upstream, the ribbon 42, after having passed over the roller 40 being brought gradually into contact with the underside of the flange 31, which is brought by a portion of conveyor belt 21 slightly inclined relative to the guide table 44. A fixed support of the porous belt 21, disposed upstream of the pulley 22 and preferably consisting of a ring of ceramic material 22c capable of withstanding the abrasion caused by the passage of the porous belt 21, modifies the path followed by said porous belt in order to make it move parallel to the guide table 44, on the path portion located between said ring 22c and the point located to the right of the axis of the pulley 22. Thus, the flange 31 is progressively tightened between the belt 21 and the second belt 41, respectively the paper tape 42. These two elements elements moving at the same speed, a simultaneous drive of said flange by these two means therefore takes place on a portion of the guide table 44, before the drive by the belt 2 does not stop at right angles to the axis of the pulley 22. This procedure significantly improves the drive of the flange 31 and significantly reduces the risks of irregular filling and tearing of the flange 31. The distance separating the two belts 21 and 41 when they run parallel to each other, that is to say on the portion of the path located between the fixed ring 22c and the point located to the right of the axis of the pulley 22 , is such that the flange 31 undergoes a certain compression in the direction of the height; this compression taking place between two drive elements does not cause the tobacco to heat up.

Le diamètre de la poulie 22 a été réduit par rapport à celui de la poulie correspondante de l'ancienne exécution, ce qui diminue ainsi la section à contrôler afin d'éviter la perte de dépression à l'intérieur de la poutre. Ainsi, le sabot de raclage qu'il était nécessaire auparavant de fixer directement sur la poutre peut être supprimé et remplacé par un nouveau doigt de guidage 45 remplissant les fonctions du sabot racleur et du doigt de guidage selon l'ancienne exécution. Le doigt de guidage 45 est fixé sur le bâti 1 de la machine, de manière à pouvoir ajuster sa position transversale par rapport au boudin. Les moyens d'ajustement sont de technique connue et ne sont donc pas décrits plus avant. Le doigt de guidage 45 a aussi son extrémité avant concave, de forme semi-circulaire, venant à proximité immédiate de la courroie 21 sur la poulie 22. L'axe de rotation de la poulie 22 est supporté par un étrier 25 qui supporte aussi l'axe de rotation de la première poulie de renvoi 22b. En agissant sur un axe de fixation pivotant 26 de l'étrier 25, il est possible de faire basculer légèrement l'étrier 25 et, par conséquent, de régler la position longitudinale de la poulie 22 en face du doigt de guidage 45. Ainsi, le réglage des positions relatives de la poulie 22 et du doigt de guidage 45 se fait de manière très simple, la position longitudinale étant ajustée sur l'axe pivotant 26, alors que la position transversale est ajustée sur le doigt de guidage 45. Sur le dispositif selon l'invention, la poulie 22 n'est plus une poulie entraînante, l'entraînement de la courroie 21 se faisant uniquement à partir de la poulie 22a.The diameter of the pulley 22 has been reduced compared to that of the corresponding pulley of the old version, thereby reducing the section to be checked in order to avoid the loss of vacuum inside the beam. Thus, the scraper shoe which previously had to be fixed directly to the beam can be eliminated and replaced by a new guide finger 45 fulfilling the functions of the scraper shoe and the guide finger according to the old embodiment. The guide finger 45 is fixed to the frame 1 of the machine, so as to be able to adjust its transverse position relative to the flange. The adjustment means are of known technique and are therefore not described further. The guide finger 45 also has its concave front end, of semi-circular shape, coming in close proximity to the belt 21 on the pulley 22. The axis of rotation of the pulley 22 is supported by a stirrup 25 which also supports the axis of rotation of the first return pulley 22b. By acting on a pivoting fixing pin 26 of the stirrup 25, it is possible to slightly tilt the stirrup 25 and, consequently, to adjust the longitudinal position of the pulley 22 opposite the guide finger 45. Thus, the relative positions of the pulley 22 and the guide finger 45 are adjusted very simply, the longitudinal position being adjusted on the pivoting axis 26, while the transverse position is adjusted on the guide finger 45. On the device according to the invention, the pulley 22 is no longer a driving pulley, the drive of the belt 21 taking place only from the pulley 22a.

A la figure 3, on a quelques vues de détail du doigt de guidage 45 selon l'invention, la figure 3A en étant une élévation, la figure 3B une vue de côté et la figure 3C une vue par-dessous. On voit que le doigt de guidage 45 se compose de trois éléments, tout d'abord d'une plaque support verticale 45a, d'une plaque de fixation 45b et de la partie de guidage proprement dite 45c. La plaque verticale 45a et la plaque de fixation 45b peuvent être taillées dans la même pièce ou être assemblées par soudure ou par n'importe quel moyen, de façon que la plaque de fixation 45b, qui sera fixée au dispositif d'ajustage de position transversale du doigt de guidage 45, se présente perpendiculairement à la face supérieure de la plaque verticale 45a. La partie de guidage 45c est soudée à la partie inférieure de la plaque verticale 45a; on voit à la figure 3B que sa face inférieure comprend une rainure, l'extrémité avant 45d de ladite rainure étant en forme semi-carrée 45e, alors que l'extrémité arrière 45f a une section à peu près semi-circulaire 45g. Sur la figure 3C, on voit que cette rainure est en forme de semi-tronc de cône, et sur la figure 3A, que l'axe de cette rainure est légèrement décalé par rapport à l'horizontale; cette disposition permet une bonne formation du boudin qui doit passer d'une section approximativement carrée lorsqu'il quitte la courroie 21, étant légèrement comprimé comme expliqué précédemment, et passe l'extrémité 45d à une section circulaire lorsqu'il quitte la partie arrière 45f du doigt de guidage et qu'il est enveloppé du ruban de papier. Afin de diminuer au maximum le frottement du boudin contre les parois de la rainure provoquant un échauffement du tabac ainsi qu'un cisaillement du boudin et une usure prématurée de la rainure, les dimensions de la rainure sont telles que le boudin comprimé précédemment retrouve petit à petit son volume lors de son passage sous le doigt de guidage et soit formé selon une section circulaire avec un frottement minime contre les parois de l'élément statique que forme la rainure du doigt de guidage. La partie avant de la plaque verticale 45a est découpée en forme de segment de cercle afin de pouvoir approcher la partie avant de la partie de guidage 45c le plus près possible de la courroie 21.In Figure 3, there are some detailed views of the guide finger 45 according to the invention, Figure 3A being an elevation, Figure 3B a side view and Figure 3C a view from below. It can be seen that the guide finger 45 consists of three elements, first of all a vertical support plate 45a, a fixing plate 45b and the guide part itself 45c. The vertical plate 45a and the fixing plate 45b can be cut in the same piece or be assembled by welding or by any means, so that the fixing plate 45b, which will be fixed to the transverse position adjustment device of the guide finger 45, is perpendicular to the upper face of the vertical plate 45a. The guide part 45c is welded to the lower part of the vertical plate 45a; we see in Figure 3B that its underside comprises a groove, the front end 45d of said groove being in semi-square shape 45e, while the rear end 45f has a roughly semi-circular section 45g. In FIG. 3C, it can be seen that this groove is in the form of a semi-truncated cone, and in FIG. 3A, that the axis of this groove is slightly offset with respect to the horizontal; this arrangement allows good formation of the flange which must pass from an approximately square section when it leaves the belt 21, being slightly compressed as explained above, and passes the end 45d to a circular section when it leaves the rear part 45f of the guide finger and that it is wrapped in paper tape. In order to minimize the friction of the flange against the walls of the groove causing a heating of the tobacco as well as shearing of the rod and premature wear of the groove, the dimensions of the groove are such that the previously compressed rod gradually regains its volume during its passage under the guide finger and is formed according to a circular section with minimal friction against the walls of the static element formed by the groove of the guide finger. The front part of the vertical plate 45a is cut in the shape of a segment of a circle in order to be able to approach the front part of the guide part 45c as close as possible to the belt 21.

Ainsi, le dispositif selon l'invention permet d'améliorer sensiblement la qualité du boudin de tabac, tout d'abord en permettant que ce boudin soit mieux entraîné lors de son passage de la partie de la machine chargée de le confectionner à celle chargée de le mettre sous papier, en diminuant les frottements entre le boudin en mouvement et les parties statiques, puis en facilitant les opérations de réglage de l'alignement des pièces par lesquelles passe ledit boudin, ce qui améliore la qualité du tabac constituant le boudin, son remplissage, et diminue les risques de déchirure de ce boudin. Le dispositif selon l'invention contribue ainsi à améliorer le rendement de la machine à cigarettes en diminuant les risques de malformation du boudin et en diminuant l'usure des pièces en frottement.Thus, the device according to the invention makes it possible to substantially improve the quality of the tobacco rod, first of all by allowing this rod to be better entrained during its passage from the part of the machine responsible for making it to that responsible for put it under paper, by reducing the friction between the moving rod and the static parts, then by facilitating the operations of adjusting the alignment of the parts through which said rod passes, which improves the quality of the tobacco constituting the rod, its filling, and reduces the risk of tearing of this tube. The device according to the invention thus contributes to improving the efficiency of the cigarette machine by reducing the risks of malformation of the rod and by reducing the wear of the parts in friction.
