Definitions
- the present invention relates to a cigarette making machine of the type equipped to manufacture two continuous cigarette rods simultaneously.
- Twin-track cigarette makers utilized in the tobacco industry are equipped with a carding unit designed to generate a flow of shredded tobacco particles, and operate by producing two continuous cigarette rods at one time.
- the flow of tobacco is fed typically into an ascending duct, or chimney, inside which the particles are carried forcibly upwards and into contact with two aspirating belts positioned to enclose the chimney at the top end.
- the particles are gathered progressively into two continuous streams; the two streams are thereupon enveloped by strips of paper and formed into two continuous cigarette rods, each of which then advances along a relative path through downstream processing stations.
- the flow of tobacco particles emerging from the chimney is not always perfectly uniform, due to an uneven distribution of the selfsame particles that derives from their dissimilar physical properties. Consequently, the two resulting streams of tobacco formed on the belts may present a different depth and/or weight per unit of length.
- Air is introduced at an initial velocity in such a manner as to "launch”, then entrain and guide the particles of tobacco until the flow rates of the air and the tobacco are equalized. It is in the upper part of the chimney that the air flow rate becomes slower, due to the widening cross section of the chimney, and tends to attenuate the velocity of the tobacco particles, especially that of the smaller particles charged with less kinetic energy. Thus, not all of the tobacco particles are able to reach the aspirating belts, by reason of their dissimilar size, specific weight and aerodynamic behaviour.
- the object of the present invention is to provide a cigarette maker equipped to manufacture two continuous cigarette rods simultaneously, in which all of the aforementioned drawbacks are overcome.
- One object of the invention is to provide a machine for manufacturing two continuous cigarette rods simultaneously, such as will allow a uniform distribution of the tobacco particles to be obtained on the two aspirating belts.
- numeral 1 denotes a machine, in its entirety, equipped to manufacture two continuous cigarette rods simultaneously.
- the machine 1 presents a first portion denoted 2, by which a continuous flow of shredded tobacco particles is fed to a second portion denoted 3; during their passage through the second portion 3, the particles are distributed in such a way as to form two continuous streams 4 of tobacco.
- the first portion 2 comprises a substantially horizontal internal duct 5 housing a power driven conveyor belt 6, looped at opposite ends around two pulleys 7 of which one only can be seen in figure 2.
- the top branch of the belt 6 is positioned to take up shredded tobacco from a carding unit of familiar type (shown in figure 1) and transfer it beyond the downstream pulley 7 into a feed chamber 8 communicating uppermost, by way of a gap between two rollers 9 and 10 contrarotating about parallel horizontal axes, with a channel 11 aligned on a substantially vertical axis 12 and delimiting an ascending duct, or chimney 13.
- the chimney 13 comprises a bottom inlet end 14, communicating with the chamber 8, and a top outlet end 15 enclosed by a pair of aspirating conveyor belts 16.
- the two aspirating belts 16 are driven in a predetermined conveying direction substantially normal to the viewing plane of figure 2, hence transverse to the axis 12 of the chimney 13, and made preferably of a permeable fabric.
- the shredded tobacco particles are carried up through the chimney 13 on an ascending current of air and formed gradually into a continuous stream 4 on each of the aspirating belts 16.
- Each stream 4 of tobacco, responding to selected physical specifications of depth, weight, moisture content and so forth, is formed into a continuous cigarette rod that will be divided subsequently into single cigarette sticks (not illustrated) by rotary cutter means (likewise not illustrated).
- a separator 17 of familiar type appearing as a bar of substantially ogival section, positioned facing the interior of the chimney 12 and extending parallel to the length dimension of the aspirating belts 16.
- the machine 1 is equipped further with pneumatic means 18 by which the aforementioned ascending flow of air is generated internally of the chimney 13; such means comprise a source 19 of compressed air connected to a duct 20 of which an outlet end 20a is located inside the feed chamber 8, positioned below the pulley 7 and directed toward the inlet end 14 of the chimney 13.
- the chimney 13 presents a lower first segment 21 equipped with means 22 by which to counter the deceleration in the flow of tobacco particles, consisting in at least two side walls, or flaps 23, located internally of the channel 11.
- the lower first segment 21 extends into an upper second segment 24 delimited by the walls 25 of the channel 11, which extend divergently toward the top outlet end 15 of the chimney 13.
- Figure 2a illustrates a first configuration in which the two flaps 23 are disposed parallel one with another, with the result that the lower first segment 21 of the chimney 13 presents a cross section of constant width.
- Figure 2b shows a second configuration in which the flaps 23 are angled one relative to the other, and more exactly convergent, in such a way that the first segment 21 of the chimney 13 presents a cross section decreasing in width from the bottom inlet end 14 upwards.
- the flaps 23 are flat.
- the flaps 23 can be curved as in the example of figure 2c, with respective convex faces directed toward the inside of the chimney 13, and the first segment 21 again presenting a cross section that decreases in width from the bottom inlet end 14 upwards.
- the lower first segment 21 of the chimney 13 and the relative means 22 of countering deceleration in the flow of ascending particles will extend from the bottom inlet end 14 of the chimney 13 to a height between 10% and 70% of the overall height of the chimney 13, and preferably between 15% and 40% of this same height.
- the optimum height of the first segment 21 is around 25% of the full height of the chimney 13.
- the flaps 23 are pivotable about axes 26 transverse to the axis 12 of the chimney 13 in such a way that their angle of inclination can be adjusted, and the cross section of the passage presented by the first segment 21 of the chimney 13 thus varied selectively.
- the flaps 23 can be moved between a position of parallel alignment one with another and a position of upward convergence one with another.
- the height of the aforementioned upper second segment 24 is preferably at least 30% of the full height of the chimney 13. As mentioned previously, the second segment 24 is delimited by the walls 25 of the channel 11, which present a substantially Vee formation as viewed in the drawings.
- the machine 1 also comprises control devices 27 of conventional type, such as will monitor selected parameters to which the streams 4 of tobacco retained by the belts 16 must respond.
- the control devices 27 operate in conjunction with actuator means 28 by which the flaps 23 in the first segment 21 of the chimney 13 can be positioned at a selected angle of inclination.
- the channel 11 presents an area between the first segment 21 and the second segment 24, in particular between the free top ends 29 of the flaps 23 and the relative surfaces 25a of the channel walls 25, identifiable as a join zone 30.
- the join zone 30 preferably establishes a smooth transition from the first segment 21 to the second segment 24, such as will to prevent any tobacco particles from penetrating between the flaps 23 and the surfaces 25a presented by the walls 25 of the channel 11.
- the free ends 29 of the flaps 23 occupying the join zone 30 present bevels and localized breaks in continuity that can create vortices or turbulence.
- a suitable join zone 30 can be created utilizing flexible membranes (not illustrated) to connect the free ends 29 of the flaps 23 with the surfaces 25a of the relative walls 25 of the channel 11.
- Each accelerator 31 comprises a vacuum unit 32 positioned externally of the channel 11 and communicating with the interior of the chimney 13 via a plurality of suction holes 33.
- each of the flaps 23 might consist in a plurality of portions, each adjustable for angular position in such a way that the geometry of the lower first segment 21 of the chimney 13 can be varied further, according to the required velocity of the air flow.
- the flaps 23 might be rigidly associated with the walls 25 of the channel 11, or embodied as relative lower portions 25b of these same walls. Likewise in this instance, it remains possible to obtain the three configurations described above, namely with walls in the lower segment extending parallel, convergent and rectilinear or convergent and curvilinear when seen in section.
- the shredded tobacco directed from the top branch of the conveyor belt 6 into the feed chamber 8 is launched toward the chimney 13 both by the force of the rollers 9 and 10 and by the flow of compressed air from the duct 20.
- the flow of tobacco particles is admitted to the chimney 13 via the inlet end 14 delimited by the contrarotating rollers 9 and 10, whereupon it rises through the first segment 21 and then through the second segment 24.
- the two parts of the flow of tobacco particles split by the separator element 17 are attracted in a state of uniform distribution by the aspirating belts 16, and formed gradually into two continuous streams 4.
- the parallel or tapered section presented by the lower first segment 21 has the effect of significantly reducing the tendency of the air flow to slow the progress of the tobacco particles in the upper segment 24 of the chimney, while maintaining a uniform flow of tobacco up to the point of impact against the aspirating belts 16.
- the initial velocity of the air and of the tobacco particles will remain substantially constant throughout the entire dwell internally of the first segment 21, whereupon the velocity decreases through the second segment 24 of divergent section.
- the velocity both of the air and of the tobacco particles will be accelerated.
- the shredded tobacco particles undergo a deceleration along the divergent section, becoming uniformly distributed and dividing appropriately between the two aspirating belts 16.
- the second segment 24 of the ascending channel 11 necessarily presents a divergent profile when seen in section, given that the width of the chimney at the top outlet end is determined by the transverse dimension of the paired aspirating belts 16, which extend side by side and are separated one from another by the ogival bar 17.
- the chimney 13, and in particular the lower first segment 21, is configured in such a way that the final velocity at which the tobacco particles hit the belts 16 can be increased, by varying the angle of the flaps 23, to between three and four times the initial velocity at which the tobacco particles are fed into the chimney 13.
- the velocity at which the tobacco particles hit the belts 16 is higher by 50-60% than the corresponding impact velocity of the tobacco in other prior art machines.
- correction signals are sent to the actuator means 28 and the angle of the flaps 23 is adjusted accordingly.
- the adjustment in question can be independent and dissimilar for the two single flaps 23 so as to compensate and cancel out any non-symmetrical distribution of the tobacco on the two aspirating belts 16.
- the angle of the flaps 23 might also be adjusted manually.
- the invention affords significant advantages.
