Definitions
- the tobacco is brought in a continuous flow to a clipping and compression device where a regular tobacco rod is formed before being covered with cigarette paper and then cut into individual cigarettes.
- a regular tobacco rod is formed before being covered with cigarette paper and then cut into individual cigarettes.
- the tobacco flow in the device it is first compressed locally and then the amount of tobacco exceeding that necessary for the preparation of the rod is eliminated by a clipping device.
- the disadvantage of such a device is that the thickness of the tobacco flow is absolutely irregular before the cam compresses a segment thereof; therefore, compressed segments are obtained whose densities of tobacco different from one to the other, since the compression cam can act on very different flow thicknesses from each other. It is obvious that thereafter this thickness is regulated by the clipping knives, as described for example in documents DE-A-3 407 893 or EP-A-0 259 071, but irregularities in tobacco density nevertheless remain in the compressed segments.
- a device for controlling the flow of tobacco according to the invention is arranged upstream of the clipping and compression device.
- the clipping and compression device 1 visible in FIG. 1, corresponds to that described in the patent application mentioned above; it consists mainly of an endless belt 10, driven in translation between the two pulleys 10a and 10b, any of these pulleys being driven in rotation by a motor not shown in the figure, of a compression cam 11 and two rotary knives 12 clipping the excess tobacco.
- This tobacco 2 comes from an intermediate stock 13 from which it is sucked through the belt 10, so that the tobacco strands come together against the belt 10, forming a layer 20, limited in width by two side rails 14 and 15 (visible in Figures 2 and 3).
- the layer 20 is irregular, that is to say that its thickness is uneven; if there was no flow control device before the cam 11, it would act sometimes on a thin layer, sometimes on a layer of greater thickness, which would lead to irregularities in the segments densified by the cam 11, of the output flange 21.
- the flow control device 3 consists of a motor 30, which can be electric, pneumatic or hydraulic, rotating at constant speed and connected by a clutch 31 to a disc 32 of cylindrical shape rotating in a plane arranged perpendicular to the irregularities of the layer 20, around an axis of rotation arranged perpendicular to the direction of advance of said layer.
- the upper circular circular face 32a of the disc 32 is located in a plane just below the lower faces 14a and 15a of the side rails 14 and 15, while as seen in Figure 3, the axis of rotation of the disc 32 is offset from the line of passage of the layer so that the layer 20 is intercepted by a portion of the outer cylindrical surface 32b of the disc 32 located proximity to the place where this external cylindrical surface 32b moves parallel to the layer 20 and in the same direction as it.
- the portion of the surface 32b intercepting the layer 20 deflects the part 22 of the layer 20 located below the upper circular surface 32a.
- the speed of rotation of the disc 32 is such that the peripheral speed of the cylindrical surface 32b is close to the speed of translation of the layer 20, the excess tobacco strands 22 are delicately separated from the layer 20, without being torn off or torn; this surplus tobacco is eliminated by the side of the disc 32 and falls on a transport device which can be a belt transport device 16a and 16b where it is mixed with the surplus tobacco 23 eliminated by the clipper 12 in order to be recycled and returned to the intermediate stock 13.
- said layer has a regular thickness, determined by the distance separating the belt 10 from the upper circular surface 32a. So that this thickness is truly uniform, it is necessary that the minimum thickness of the layer 20, before it passes over the disc 32, is always greater than said regulated thickness.
- the cam 11 acts to compress a segment of the layer, it always acts on the same thickness of this layer, which makes the density of the tobacco of the different compressed segments of the final roll uniform. 21.
- the clutch coupling 31 is located between the engine 30 and the disc 32; it is indeed necessary, during the launching of the machine, to cause the disc 32 to rotate at a speed such that its peripheral linear speed is approximately the running speed of the layer 20; thereafter, the friction of the lower face of the layer against the upper circular surface 32a is sufficient to drive the disc 32 at good speed; it is therefore possible to decouple the drive of said disc by the clutch coupling 31 and to cut off the power supply to the motor 30. It is understood that it is quite possible to provide an embodiment of the device according to the invention does not include this declutching, the disc 32 remaining continuously driven by the motor 30.
- the speed of movement of the layer of tobacco in a machine of the type described is of the order of 500 to 1000 m / min.
- the disc In order to have a regular separation of the surplus 22 from the tobacco layer 20, various precautions must be taken with regard to the geometry of the disc as well as its constituent material; in particular the outer cylindrical surface 32b of the disc 32 must be arranged perpendicular to the direction of passage of the layer 20 in order to correctly eliminate the excess 22 from the side; misalignment of this surface 32b, in one direction or the other, would lead to a slight compression or depression of the layer of controlled thickness, which would harm its regularity.
- the material of the disc must be chosen so that the tobacco particles do not adhere to the disc, for this, according to a preferred embodiment, the disc is made of POLYDUR (registered trademark of LEDER & Co.
- the disc can be made of any material covered with a layer or a coating on which the tobacco does not adhere.
- the surface condition of the faces 32a and 32b of the disc is absolutely smooth.
- the tobacco flow control device according to the invention has been described mounted just before a clipping and compression device in which the tobacco flow is sucked against a belt which moves it; other clipping and compression systems exist on which the device according to the invention can equally well be applied. More generally, whatever the geometry according to which the tube is formed, the device according to the invention can be applied to adjust the thickness of said tube. Similarly, the device can be applied to any device for clipping and reinforcing the sausage requiring regulation of the thickness of the layer of tobacco before reinforcement and clipping, regardless of the way in which the strengthening of the ends of cigarettes is carried out. .
- the device for controlling a flow of tobacco according to the invention is particularly suitable for regulating the thickness of a layer of tobacco of irregular thickness, before it enters the reinforcement or compression device, so that the segments of the sausage having a higher density all have the same density.
- the device according to the invention eliminates the surplus of tobacco without the latter being damaged.

- Manufacturing Of Cigar And Cigarette Tobacco (AREA)
Description
Lors de la fabrication de cigarettes, le tabac est amené en un flux continu vers un dispositif d'écrêtage et de compression où un boudin de tabac régulier est formé avant d'être recouvert du papier à cigarettes puis coupé en cigarettes individuelles. Au cours du passage du flux de tabac dans le dispositif, celui-là est tout d'abord comprimé localement puis la quantité de tabac excédant celle nécessaire à la confection du boudin est éliminée par un dispositif d'écrêtage.During the manufacture of cigarettes, the tobacco is brought in a continuous flow to a clipping and compression device where a regular tobacco rod is formed before being covered with cigarette paper and then cut into individual cigarettes. During the passage of the tobacco flow in the device, it is first compressed locally and then the amount of tobacco exceeding that necessary for the preparation of the rod is eliminated by a clipping device.
Un tel dispositif d'écrêtage et de compression est décrit dans la demande de brevet EP-A-0 354 874. Dans ce dispositif, le tabac est aspiré afin de venir s'agglomérer contre une mince courroie poreuse se déplaçant longitudinalement, cette courroie transporte le tabac entre deux rails latéraux et l'amène tout d'abord vers une came qui comprime légèrement le tabac, c'est-à-dire augmente sa densité sur une courte distance; le boudin de tabac passe immédiatement après dans un dispositif d'écrêtage, constitué de deux couteaux circulaires en rotation, chargé d'éliminer le surplus de tabac afin d'obtenir un boudin régulier de tabac qui comporte des segments également espacés où la densité de tabac est plus élevée que dans le reste du boudin; les cigarettes individuelles seront ensuite coupées sur ces segments à plus haute densité ou renforcés qui forment alors des sortes de bouchons empêchant le tabac de s'échapper de la cigarette.Such a clipping and compression device is described in patent application EP-A-0 354 874. In this device, the tobacco is sucked up in order to come to agglomerate against a thin porous belt moving longitudinally, this belt transports the tobacco between two side rails and first leads it to a cam which slightly compresses the tobacco, that is to say increases its density over a short distance; the tobacco rod immediately passes through a clipping device, consisting of two circular knives in rotation, responsible for removing excess tobacco in order to obtain a regular rod of tobacco which has equally spaced segments where the density of tobacco is higher than in the rest of the sausage; the individual cigarettes will then be cut on these higher density segments or reinforced which then form kinds of plugs preventing the tobacco from escaping from the cigarette.
L'inconvénient d'un tel dispositif est que l'épaisseur du flux de tabac est absolument irrégulière avant que la came n'en comprime un segment; de ce fait, on obtient des segments comprimés dont les densités de tabac différent de l'un à l'autre, vu que la came de compression peut agir sur des épaisseurs de flux très différentes les unes des autres. Il est évident que par la suite cette épaisseur est régulée par les couteaux d'écrêtage, comme décrit par exemple dans les documents DE-A-3 407 893 ou EP-A-0 259 071, mais des irrégularités de densité de tabac subsistent néanmoins dans les segments comprimés.The disadvantage of such a device is that the thickness of the tobacco flow is absolutely irregular before the cam compresses a segment thereof; therefore, compressed segments are obtained whose densities of tobacco different from one to the other, since the compression cam can act on very different flow thicknesses from each other. It is obvious that thereafter this thickness is regulated by the clipping knives, as described for example in documents DE-A-3 407 893 or EP-A-0 259 071, but irregularities in tobacco density nevertheless remain in the compressed segments.
Afin d'éliminer cet inconvénient et par là d'augmenter la régularité de la production de cigarettes, il est nécessaire de contrôler le flux de tabac, c'est-à-dire son épaisseur, avant que celui-ci ne pénètre dans le dispositif d'écrêtage et de compression.In order to eliminate this drawback and thereby increase the regularity of cigarette production, it is necessary to control the flow of tobacco, that is to say its thickness, before it enters the device. clipping and compression.
D'autre part, il est nécessaire que le tabac en surplus et qui doit donc être éliminé du boudin ne soit pas endommagé, c'est-à-dire que les brins de tabac ne soient pas déchirés ou arrachés, c'est pourquoi des dispositifs simples comme un couteau racleur, une brosse fixe ou tournante ou une roue à palletes, comme décrite dans GB-A-2 072 483, ne peuvent être utilisés puisqu'ils endommagent les brins de tabac.On the other hand, it is necessary that the tobacco in excess and which must therefore be removed from the rod is not damaged, that is to say that the tobacco strands are not torn or torn off, this is why simple devices such as a scraper knife, a fixed or rotating brush or a paddle wheel, as described in GB-A-2 072 483, cannot be used since they damage the tobacco strands.
Pour contrôler, avant la compression, l'épaisseur de la couche de tabac devant former le boudin, en évitant d'endommager le tabac, un dispositif de contrôle du flux de tabac selon l'invention, conforme aux parties caractérisantes des revendications, est disposé en amont du dispositif d'écrêtage et de compression.To control, before compression, the thickness of the layer of tobacco to form the rod, avoiding damaging the tobacco, a device for controlling the flow of tobacco according to the invention, in accordance with the characterizing parts of the claims, is arranged upstream of the clipping and compression device.
Le fonctionnement du dispositif de contrôle du flux de tabac est particulièrement compréhensible par la description d'une forme d'exécution préférentielle dudit dispositif en regard du dessin avec les figures où:
- la figure 1 représente une vue en élévation d'un dispositif d'écrêtage et de compression précédé d'un dispositif de contrôle du flux de tabac,
- la figure 2 représente une vue en élévation du dispositif de contrôle du flux de tabac selon une forme d'exécution préférentielle, et
- la figure 3 représente une vue en plan par dessus du dispositif de contrôle du flux de tabac.
- FIG. 1 represents an elevation view of a clipping and compression device preceded by a device for controlling the flow of tobacco,
- FIG. 2 represents an elevation view of the device for controlling the flow of tobacco according to a preferred embodiment, and
- Figure 3 shows a plan view from above of the tobacco flow control device.
Le dispositif d'écrêtage et de compression 1, visible à la figure 1, correspond à celui décrit dans la demande de brevet mentionnée plus haut; il est constitué principalement d'une courroie sans fin 10, entraînée en translation entre les deux poulies 10a et 10b, l'une quelconque de ces poulies étant entraînée en rotation par un moteur non représenté sur la figure, d'une came de compression 11 et de deux couteaux rotatifs 12 écrêtant le surplus de tabac. Ce tabac 2, provient d'un stock intermédiaire 13 duquel il est aspiré à travers la courroie 10, afin que les brins de tabac viennent s'agglomérer contre la courroie 10, formant une couche 20, limitée en largeur par deux rails latéraux 14 et 15 (visibles sur les figures 2 et 3). On remarque que la couche 20 est irrégulière, c'est-à-dire que son épaisseur est inégale; si on ne disposait pas de dispositif de contrôle du flux avant la came 11, celle-ci agirait tantôt sur une couche de faible épaisseur, tantôt sur une couche d'épaisseur plus importante, ce qui amènerait à des irrégularités dans les segments densifiés par la came 11, du boudin de sortie 21. Pour éviter ceci, le dispositif de contrôle de flux 3 est constitué d'un moteur 30, pouvant être électrique, pneumatique ou hydraulique, tournant à vitesse constante et relié par un embrayage 31 à un disque 32 de forme cylindrique tournant dans un plan disposé perpendiculairement aux irrégularités de la couche 20, autour d'un axe de rotation disposé perpendiculairement au sens d'avance de ladite couche.The clipping and
Comme on le voit à la figure 2, la face plane circulaire supérieure 32a du disque 32 est située dans un plan juste dessous les faces inférieures 14a et 15a des rails latéraux 14 et 15, alors que comme on le voit sur la figure 3, l'axe de rotation du disque 32 est décalé par rapport à la ligne de passage de la couche de manière à ce que la couche 20 soit interceptée par une portion de la surface cylindrique extérieure 32b du disque 32 située à proximité de l'endroit où cette surface cylindrique extérieure 32b se déplace parallèlement à la couche 20 et dans le même sens qu'elle.As seen in Figure 2, the upper circular
Ainsi, lorsque le disque 32 est en rotation, selon le sens de la flèche de la figure 3, la portion de la surface 32b interceptant la couche 20 dévie la partie 22 de la couche 20 située au-dessous de la surface circulaire supérieure 32a. Lorsque la vitesse de rotation du disque 32 est telle que la vitesse périphérique de la surface cylindrique 32b est proche de la vitesse de translation de la couche 20, les brins de tabac en surplus 22 sont délicatement séparés de la couche 20, sans être arrachés ou déchirés; ce tabac en surplus est éliminé par le côté du disque 32 et tombe sur un dispositif de transport pouvant être un dispositif de transport à bandes 16a et 16b où il est mélangé avec le surplus de tabac 23 éliminé par l'écrêteur 12 afin d'être recyclé et de retourner dans le stock intermédiaire 13. Ainsi, après passage de la couche 20 au-dessus du disque 32, ladite couche a une épaisseur régulière, déterminée par la distance séparant la courroie 10 de la surface circulaire supérieure 32a. Afin que cette épaisseur soit vraiment uniforme, il est nécessaire que l'épaisseur minimum de la couche 20, avant que celle-ci ne passe par dessus le disque 32, soit toujours plus grande que ladite épaisseur régulée. Ainsi, lorsque la came 11 agit pour comprimer un segment de la couche, elle agit toujours sur une même épaisseur de cette couche, ce qui rend uniforme la densité du tabac des différents segments comprimés du boudin final 21.Thus, when the
Selon une forme d'exécution prèférentielle, l'accouplement à embrayage 31 est situé entre le moteur 30 et le disque 32; il est en effet nécessaire, lors du lancement de la machine, d'amener le disque 32 à tourner à une vitesse telle que sa vitesse linéaire périphérique soit approximativement la vitesse de défilement de la couche 20; par la suite, le frottement de la face inférieure de la couche contre la surface circulaire supérieure 32a est suffisant pour entraîner le disque 32 à bonne vitesse; il est donc possible de découpler l'entraînement dudit disque par l'accouplement à embrayage 31 et de supprimer l'alimentation du moteur 30. Il est bien entendu qu'il est tout à fait possible de prévoir une forme d'exécution du dispositif selon l'invention ne comportant pas ce débrayage, le disque 32 restant continuellement entraîné par le moteur 30. La vitesse de déplacement de la couche de tabac dans une machine du type décrit est de l'ordre de 500 à 1000 m/min.According to a preferred embodiment, the
Afin d'avoir une séparation régulière du surplus 22 de la couche de tabac 20, différentes précautions sont à prendre en ce qui concerne la géométrie du disque ainsi que sa matière constitutive; en particulier la surface cylindrique extérieure 32b du disque 32 doit être disposée perpendiculairement au sens de passage de la couche 20 afin d'éliminer correctement par le côté le surplus 22; un désalignement de cette surface 32b, dans un sens ou dans l'autre, amènerait à une légère compression ou dépression de la couche d'épaisseur régulée, ce qui nuirait à sa régularité. De même la matière constitutive du disque doit être choisie afin que les particules de tabac n'adhèrent pas au disque, pour ceci, selon une forme d'exécution préférentielle, le disque est en POLYDUR (marque déposée de LEDER & Co. AG), étant bien entendu que toute autre matière sur laquelle les brins et la poussière de tabac ne peuvent adhérer peut être utilisée; plus généralement, le disque peut être fait en un matériau quelconque recouvert d'une couche ou d'un enduit sur lequel le tabac n'adhère pas. L'état de surface des faces 32a et 32b du disque est absolument lisse.In order to have a regular separation of the
Le dispositif de contrôle d'un flux de tabac selon l'invention a été décrit monté juste avant un dispositif d'écrêtage et de compression dans lequel le flux de tabac est aspiré contre une courroie qui le déplace; d'autres systèmes d'écrêtage et de compression existent sur lesquels le dispositif selon l'invention peut tout aussi bien s'appliquer. Plus généralement, quelle que soit la géométrie selon laquelle le boudin est formé, le dispositif selon l'invention peut s'appliquer à régler l'épaisseur dudit boudin. De même, le dispositif peut s'appliquer à tout dispositif d'écrêtage et de renforcement du boudin nécessitant une régulation d'épaisseur de la couche de tabac avant renforcement et écrêtage, quelle que soit la manière dont le renforcement des bouts de cigarettes est effectué.The tobacco flow control device according to the invention has been described mounted just before a clipping and compression device in which the tobacco flow is sucked against a belt which moves it; other clipping and compression systems exist on which the device according to the invention can equally well be applied. More generally, whatever the geometry according to which the tube is formed, the device according to the invention can be applied to adjust the thickness of said tube. Similarly, the device can be applied to any device for clipping and reinforcing the sausage requiring regulation of the thickness of the layer of tobacco before reinforcement and clipping, regardless of the way in which the strengthening of the ends of cigarettes is carried out. .
Ainsi le dispositif de contrôle d'un flux de tabac selon l'invention est particulièrement apte à réguler l'épaisseur d'une couche de tabac d'épaisseur irrégulière, avant que celle-ci ne pénètre dans le dispositif de renforcement ou de compression, afin que les segments du boudin ayant une plus forte densité aient tous la même densité. De par sa construction et sa géométrie, le dispositif selon l'invention élimine le surplus de tabac sans que ce dernier ne soit endommagé. L'introduction d'un tel dispositif dans une machine de confection du boudin de tabac de cigarettes ou d'autres articles de l'industrie du tabac, permet une production plus régulière, ainsi qu'une augmentation de qualité des produits finis par une diminution des déchets.Thus the device for controlling a flow of tobacco according to the invention is particularly suitable for regulating the thickness of a layer of tobacco of irregular thickness, before it enters the reinforcement or compression device, so that the segments of the sausage having a higher density all have the same density. By virtue of its construction and its geometry, the device according to the invention eliminates the surplus of tobacco without the latter being damaged. The introduction of such a device in a machine for making the rod of tobacco from cigarettes or other articles of the tobacco industry, allows a more regular production, as well as an increase in quality. finished products by reducing waste.
