Definitions

  • the invention relates to the field of personal-use apparatus for the manufacture of cigarettes of the type using preformed paper tubes to fill with tobacco.
  • the present apparatus makes it possible to reproducibly and simply control the density of tobacco introduced into such a tube.
  • US2004 / 0099277 discloses an apparatus comprising a funnel filled with tobacco and provided with a retractable rod adapted to supply tobacco by reciprocating movements a hemicylindrical compression tank at the bottom of which is placed an elongated shovel-shaped transfer rod and in which the transferred tobacco rests.
  • a hemi-cylindrical arch is closed over the compression reservoir to compact the tobacco on the transfer rod to form a cylindrical volume of diameter just below that of paper tubes ready to be filled with tobacco.
  • the transfer rod is then moved with the tobacco cylinder that it supports and introduced into a paper tube.
  • This device can be automated by the use of motors and a controller, which increases the price.
  • a major defect of this apparatus is that the tobacco is not homogenized before being transferred to the compression tank and may include lumps which result in a cigarette having tobacco densities varying along the length of the tube.
  • FR2716344 discloses another type of tobacco filling apparatus also comprising a funnel provided with a mixing cylinder comprising rods extending radially about an axis of rotation and allowing a certain homogenization of the tobacco before it reaches a compression tank located in the bottom of the funnel.
  • a metering device may be interposed between the mixing wheel and the compression chamber to control the amount of tobacco falling into the compaction chamber. Once compacted, the tobacco is transferred to a tube using a transfer rod as described above.
  • US6739343 describes a device similar to the preceding comprising a passage defined between a cylindrical chamber and a mixing cylinder rotatably mounted in said cylindrical chamber and provided with short rods extending radially from the cylinder to the inner wall of the cylindrical chamber. At the bottom of the cylindrical chamber is a reservoir of compaction similar to those discussed above. The defect of the latter two devices is that the mixing cylinders do not allow sufficient homogenization of the tobacco before transfer into a compression chamber.
  • WO2007 / 093417 discloses an apparatus comprising a rotor accommodated in a stator.
  • the rotor is formed by a cylindrical rotary chamber whose wall is provided with openings and the stator is a static cylindrical chamber comprising a single opening in the bottom thereof, having the same geometry as the openings of the rotary chamber.
  • the rotating chamber is filled with tobacco and turning a tobacco mixture is performed.
  • tobacco can fall by gravity into a compression chamber as described above.
  • US3892245 discloses an apparatus comprising a cylindrical chamber provided with a rotary mixer composed of thin rods extending radially from the axis of rotation of the mixer along a side wall of the cylindrical chamber and once the peripheral wall is reached, forming a right angle and extending parallel to the peripheral wall.
  • the bottom of the cylindrical chamber comprises an opening communicating with a metering chamber provided with a transfer rod.
  • This apparatus does not include a compression chamber for compacting the tobacco accumulated on the transfer rod. Although the mixing of the tobacco is substantially better than in the previous apparatuses, it is not possible to reproducibly control the dosage of the paper tubes.
  • the document CA 2 647 771 A1 describes another device for the production of cigarettes.
  • each blade of the mixer is of substantially flexible reference. They may be made of an elastomeric material and / or having a thinner thickness than the rest of the blade.
  • the height, d1 of the discharge opening is advantageously between 5 and 30 mm, preferably between 10 and 25 mm.
  • the distal portion of the transfer rod is advantageously cylindrical with a diameter substantially equal to and less than D0 and the proximal portion of the transfer rod has a shovel-shaped length of between 5 and 10 cm.
  • the transfer rod is thus able to slide in the cylindrical compression chamber between a filling position to which the proximal portion is laid over substantially the entire length of the cradle of the first jaw and a transfer position to which the proximal portion is placed on the cigarette tube support and the distal portion is in the cylindrical compaction chamber.
  • the shovel-shaped proximal portion preferably has a trunk section geometry of diameter equal to that of the cylindrical distal portion, having an opening angle of 170 to 210 ° at the level where the proximal portion contacts the distal portion and a diameter slightly smaller than the inside diameter of a cigarette paper tube and a smaller opening angle than the free end of the proximal portion, preferably between 60 and 120 °.
  • the first cradle stop defining the downstream lip of the discharge opening is defined as the free end of a flat wall parallel to the axis of revolution, X1, extending the semi-cylindrical cradle, preferably on a height of between 1 and 5 mm, in order to obtain a shearing effect with the first crown defining the upstream lip of the discharge opening, for cutting tobacco particles partially in the chamber of compression and partially in the mixing chamber during the displacement of the jaws to their compression position.
  • the rotational speed, v M , of the mixer is for example between 1000 and 1500 rpm and the mixing time, t M , can be between 0.5 and 5 s.
  • a cigarette manufacturing apparatus comprises a tobacco mixing unit (1), a metering and pressing unit (5) of said tobacco, and a tobacco transfer unit thus homogenized, metered and compressed into paper cigarette tubes.
  • the tobacco mixing unit is essential to the effectiveness of the present apparatus, since it makes it possible to homogenise the tobacco before dosing it and compress it to introduce it into a cigarette paper tube. Indeed, a major defect of the apparatus of the prior art is that the homogenization of the tobacco is not sufficient and the filling of the cigarette paper tubes is not reproducible, because one can not avoid with such devices the formation of tobacco lumps or voids in the tube.
  • the mixing chamber consists of a substantially cylindrical peripheral wall around an axis of revolution, X1, and two side walls closing the sides of the chamber.
  • the mixing chamber comprises an inlet opening (not shown) for introducing tobacco into the chamber.
  • the inlet opening may be in the peripheral wall or in one of the side walls. It is preferably provided with a closure valve for closing the inlet opening once the desired amount of tobacco has been introduced into the mixing chamber.
  • the inlet opening may be equipped with an automatic or semi-automatic tobacco supply system.
  • the mixing chamber (12) also comprises a discharge opening (3) located on the peripheral wall and extending substantially the entire width, L, of said wall.
  • the discharge opening is in communication with the dosing and compression unit described below. Unlike prior art apparatuses described above, the discharge opening (3) is not at the lowest point of the metering / mixing chamber.
  • This positioning of the discharge opening (3) is favorable for a transfer of the finest particles in the compression unit (5), made possible by the rotation and geometry of the mixer (12).
  • the tobacco is not transferred to the compression chamber (5c) by gravity as is the case of the apparatuses of the prior art described above, but by the centrifugal force generated by the rotation of the mixer (12).
  • the mixer (12) of an apparatus comprises at least two blades. It can understand more, for example three or four blades as represented in the Figure 2 (c) & (D).
  • the mixer (12) is rotatably mounted about the axis, X1, of revolution of the peripheral wall of the mixing chamber (2). It has a span, Db, equal to or slightly greater than the diameter, D, of the cylindrical peripheral wall of the mixing chamber (2).
  • the span, Db, of the mixer may be slightly greater than the diameter of the mixing chamber (2) in the case where at least a portion of the blades, in particular the free end of the blades, is flexible, for example made in one piece. elastomeric material and / or having a finer section.
  • each blade comprises at least one window (12f) allowing the passage of tobacco therethrough.
  • the total area covered by the window (s) on one side of a blade preferably represents between 15 and 85% of the area of said blade face, preferably between 20 and 80%, more preferably between 25 and 80%, % and 75% of the area of said blade face.
  • the window or windows of each blade are preferably separated from the free end of said blade by a distance, Df, of at least 5 mm, preferably at least 10 mm. This allows the free end of each blade to push the tobacco particles along the peripheral wall of the mixing chamber (2).
  • the mixer is coupled to a motor (not shown in the Figures) for rotating the mixer (12) about its axis of rotation, X1, at a speed between 500 and 10000 rpm (revolutions per minute), preferably between 1000 and 1500 rpm.
  • the mixer preferably rotates in the direction such that it first scans the upstream lip of the discharge opening defined by the second jaw (5b) before scanning the downstream lip defined by the first jaw (5a).
  • the Compression Unit The Compression Unit
  • the compression unit (5) is placed adjacent to the discharge opening (3) of the mixing chamber (2). It is the compression unit (5) which controls the extent (or height) of the discharge opening (3) in the circumferential direction of the peripheral wall.
  • the compression unit (5) comprises a first jaw (5a) and a second jaw (5b) defining a volume between the two.
  • the first jaw (5a) forms a hemicylindrical cradle and is defined by first and second cradle crests each extending parallel to the axis of revolution, X1, from one side wall to the other over a substantially lengthwise length. equal to the width, L, of the mixing chamber.
  • a first stop cradle defines the downstream lip of the discharge opening (3).
  • This first cradle stop is advantageously defined as the free end of a plane wall parallel to the axis of revolution, X1, extending the semi-cylindrical cradle, as shown in FIGS. Figures 3 & 4.
  • the height of said planar wall of extension can typically be between 1 and 5 mm.
  • This configuration has two advantages. First, it allows to contain a larger amount of tobacco before compression than in the case where the lip down the discharge opening would correspond to the end of the semicylindrical part of the cradle. Secondly, it provides a shearing effect with the first crown defining the upstream lip of the discharge opening, to cut tobacco particles partially in the compression chamber (5c) and partially in the mixing chamber when moving the jaws to their compression position.
  • the second jaw (5b) forms a hemicylindrical vault defined by a first and a second arches extending each parallel to the axis of revolution, X1, from one side wall to the other over a length substantially equal to L.
  • a first vault defines the upstream lip of the discharge opening (3) of the mixing chamber.
  • the second vault extends to form a plane wall parallel to the axis of revolution, X1, and in contact with the second cradle stop, the first and second jaws (5a, 5b) are movable relative to each other.

Figures 3 (a) and 4 (a) & (b)), and a compression position to which the upstream and downstream lips of the discharge opening (3) are in contact with each other and the cradle and vault together form a cylindrical chamber of compression of diameter, D0 (cf. Figures 3 (b) and 4 (c) ).
  • the height, d1, of the discharge opening may be between 5 and 30 mm, preferably between 10 and 25 mm.
  • the height, d1 depends on the type of tobacco used, the density of tobacco in the desired cigarette, as well as the presence or absence of a blade (4) illustrated in FIG. Figure 4 and described below.
  • the translation movement of the jaws (5a, 5b) thus makes it possible, on the one hand, to control the extent (or height) of the discharge opening (3) in the circumferential direction of the peripheral wall of the chamber of mixture (2) which makes it possible to control the quantity of tobacco transferred per unit of time in the compression unit (5) and, secondly, to compact the tobacco thus transferred in a cylinder which can be introduced into a tube (10) of cigarette paper.
