Definitions

  • the present invention relates to a cigarette maker.
  • the present invention relates to a cigarette-making machine of the type equipped with means by which to form two or more continuous cigarette rods.
  • cigarette rod indicates the assemblage of the paper strip and the tobacco, from the moment when the tobacco is deposited on the paper through the step whereby the paper is wrapped around the stream of tobacco.
  • the continuous rod formed in this way is fed toward a cutter device and divided up into single sticks, each of which will provide at least one cigarette.
  • the cigarettes are conveyed to a further machine, typically a packer.
  • a cigarette maker equipped to assemble two continuous rods can be likened, for instance, to a machine producing a single imaginary rod of which the diameter is equal to the distance between centres of the two rods, plus the diameter of one rod, and will measure 3-4 cm or thereabouts.
  • the object of the present invention is to provide a high speed cigarette maker such as will be simple and economical to implement.
  • FIG. 1 denotes a portion, in its entirety, of a cigarette making machine able to fashion a plurality of continuous cigarette rods 2a, 2b and 2c simultaneously, as indicated by the section drawing of figure 3.
  • the machine 1 comprises a frame 3 carrying a feed unit by means of which to advance three strips 4 of paper, each marginally greater in width than the developable circumference of the single rods 2a, 2b and 2c in production.
  • the feed unit in question is essentially familiar in embodiment, and indicated schematically by a block 5 in figure 1.
  • the machine 1 further comprises a feeder device 6 supplying shredded tobacco 7, also a table 8 on which the continuous cigarette rods 2a, 2b and 2c are assembled.
  • the assembly table 8 likewise carried by the frame 3, comprises three conveyor belts 9a, 9b and 9c associated respectively with each of the three paper strips 4.
  • the three belts 9a, 9b and 9c are looped around a plurality of rollers 10a, 10b, 10c, 11a, 11b, 11c and 12 and set in motion by a drive roller 13, in such a way that the strips 4 are caused to advance along respective predetermined paths P1, P2 and P3 extending along the assembly table 8 and indicated in figure 2.
  • the feed unit 5 is designed to advance each of the three strips 4 onto a respective belt 9a, 9b and 9c, in such a manner that one face 4a of the strip 4 is offered in contact to a top branch 14 of the relative belt 9a, 9b and 9c.
  • each belt 9a, 9b and 9c extends along the assembly table 8 between sets of return rollers 10a-10b-10c and 11a-11b-11c located respectively downstream and upstream relative to the direction of movement of the selfsame belts.
  • each belt 9a, 9b and 9c is designed to advance a respective strip 4 along a respective path P1, P2 and P3 in a predetermined direction F1, F2 and F3, passing through a loading station 15 (figure 1) located along the selfsame path P1, P2 and P3.
  • the loading station 15 coincides with a point at which a continuous and substantially uniform stream of tobacco 7 is released onto the upwardly directed face 4b of each strip 4 by the feeder device 6 aforementioned.
  • the three streams of tobacco are substantially identical one to another and generated in familiar manner while clinging to three downwardly directed faces 16a presented by the bottom branches of three respective aspirating conveyor belts 16, familiar likewise in embodiment, forming part of the feeder device 6 and extending in part above the assembly table 8.
  • the cigarette rod 2a, 2b or 2c is identifiable as the assemblage of the paper strip 4 and the tobacco 7, from the moment in which the tobacco is released onto the face 4b of the strip 4 at the loading station 15 to the moment, subsequent to the paper being gathered around the tobacco filler into a tubular wrapper 17, when the assembled rod is separated by a cutter device into discrete lengths or sticks, not illustrated, that will emerge ultimately as single cigarettes.
  • the aforementioned cutter device is of conventional type, appearing as a cylindrical cutter head 18 rotatable about an axis 19 substantially parallel to the assembly table 8, and presenting a pair of diametrically opposed blades 18a.
  • the cutter head is indicated schematically as a block, likewise denoted 18.
  • the machine 1 further comprises guide means 100, interposed between the downstream rollers 11a, 11b and 11c and the cutter head 18, serving to direct the rods 2a, 2b and 2c from the runout ends of the respective belts 9a, 9b and 9c into the path of the blades 18a.
  • the table 8 and the guide means 100 combine to establish the aforementioned paths P1, P2 and P3 followed by the respective cigarette rods 2a, 2b and 2c.
  • the assembly table 8 comprises three divisions consisting in beams on which the three continuous rods 2a, 2b and 2c are formed, denoted 20a, 20b and 20c respectively.
  • the forming beams 20a, 20b and 20c are identical one to another, conventional in embodiment and not illustrated in detail.
  • the three beams extend one beside another along the relative paths P1, P2 and P3 downstream of the loading station 15, following the feed directions F1, F2 and F3 of the strips 4.
  • the three paths P1, P2 and P3 are convergent, as will be explained in due course, and in particular, the two lateral divisions 20a and 20c are disposed symmetrically and convergently on opposite sides of the central division 20b.
  • the cigarette rods 2a, 2b and 2c are illustrated in section, in figure 3, and in plan in figures 1 and 4.
  • each beam 20a, 20b and 20c affords a corresponding groove 21 proportioned to accommodate a relative belt 9a, 9b and 9c.
  • the groove 21 presents a cross-sectional profile of varying geometry that narrows to the point of assuming an essentially cylindrical shape with a radius of curvature substantially matched to the radius of the single cigarette.
  • Each belt 9a, 9b and 9c thus extends along a respective groove 21 in contact with the concave profile, and is caused to bend progressively until forced into the substantially cylindrical shape aforementioned.
  • the relative paper strip 4 is caused likewise to roll around the respective stream of tobacco 7 and form the corresponding tubular wrapper 17.
  • each paper strip 4 is engaged by a gumming device of familiar embodiment (not illustrated), and thereupon joined to the other edge to seal the rod 2a, 2b and 2c.
  • Figure 3 is a schematic representation showing the cross-sectional profile of the central beam 20b at a point along the feed direction F2 beyond the formation of the substantially cylindrical section described above.
  • the section shown in figure 3 illustrates a moment in which the belt 9b, rolled previously into a cylindrical tube to form the rod 2b, begins opening out again gradually to a flat profile before passing around the cylindrical return roller 11b.
  • the upstream rollers 10a, 10b and 10c and the downstream rollers 11a, 11b and 11c at the opposite ends of the respective branches 14 are necessarily cylindrical, presenting an axial length substantially equal to the width of the respective belt 9a, 9b and 9c, since a roller of any shape other than cylindrical will not allow the belt 9a, 9b and 9c to form a clean loop.
  • the cutter device 18 operates in conjunction with a striker device by which the continuous rods 2a, 2b and 2c are supported and guided during the step of cutting the sticks.
  • the feed paths P1, P2 and P3 lie substantially in a common plane G, at least on a line coinciding with or immediately upstream of the cutter head 18.
  • the feed paths P1, P2 and P3 and the relative beams 20a, 20b and 20c are shown in figures 2 and 4 as being positioned one relative to the next, in the common plane G, at an angle ⁇ of convergence that has been accentuated in the drawings for the sake of clarity, but which in practice will be less than 5°.
  • the angle ⁇ of convergence will be less than 1°.
  • the feed paths P1, P2 and P3 might not occupy a common plane, at least on a line coinciding with or immediately upstream of the cutter head 18.
  • the central or middle path P2 of the three paths P1, P2 and P3 will lie above or below the level of the plane occupied by the two outer or lateral paths P1 and P3.
  • the three paths P1, P2 and P3 followed by the three cigarette rods 2a, 2b and 2c combine, in a plane perpendicular to at least one of the paths P1, P2 and P3 and coinciding with or immediately upstream of the cutter head 18, to describe corresponding points T1, T2 and T3 on a circumference C of predetermined diameter.
  • this arrangement is particularly convenient when transferring the cigarette sticks onto the infeed drum of a filter tip attachment machine and/or when dividing up the rods 2a, 2b and 2c with a cutter device 18 that consists in a rotor of cylindrical shape carrying a pair of peripheral blades 18a, as described above.
  • the central belt 9b associated with the middle beam 20b extends further along the relative path P2 in the respective feed direction F2 than the two belts 9a and 9c located on either side.
  • the central belt 9b reassumes its flat profile, beyond the relative groove 21 of varying geometry, along a part of the respective feed path P2 that lies downstream of the part of each path P1 and P3 along which the lateral belts 9a and 9c reassume their flat profile after leaving the grooves 21.
  • the belts 9a, 9b and 9c are made of a material such that they cannot be looped around rollers tending to induce deformation (rollers with concave surfaces, for example), reducing the width at the point where the three paths P1, P2 and P3 converge. Accordingly, given that the three belts must be looped over cylindrical rollers of which the axial length will be matched to the width of the belts, as aforementioned, the three runout portions must present the type of configuration illustrated in figures 2 and 4.
  • Figure 4 illustrates the assembly table 8 in an embodiment alternative to the one illustrated in figure 2 and described in detail above.
  • the table 8 of figure 4 again presents three belts 9a, 9b and 9c extending substantially one alongside the other along the relative paths P1, P2 and P3, from the upstream rollers 10a, 10b and 10c to the downstream rollers 11a, 11b and 11c.
  • the downstream rollers 11a, 11b and 11c are positioned substantially alongside one another so that there is no projection of the central belt 9b beyond the lateral belts 9a and 9c.
  • the belts 9a, 9b and 9c constitute means 22 by which the rods 2a, 2b and 2c are conveyed along the corresponding feed paths P1, P2 and P3.
  • the guide means 100 can also be embodied so as to incorporate the striker device supporting and guiding the rods 2a, 2b and 2c during the step of cutting the rods into sticks.
  • the convergent arrangement of at least one part of the paths P1, P2 and P3 is instrumental in enabling the cigarette rods 2a, 2b and 2c to be kept particularly close together on reaching the cutter head 18, and thus ensuring that the sticks are cut correctly.
  • the convergent part of the feed paths P1, P2 and P3 could extend along the table 8 only, in which case the rods 2a, 2b and 2c would advance parallel one with another downstream of the convergent part, oriented by the guide means 100, or alternatively, the convergence could be limited to the guide means 100 only, in which case these would be equipped with suitable means by which to take up the cigarette rods 2a, 2b and 2c from beams 20a, 20b and 20c substantially parallel one with another.
