Definitions

  • the invention relates to a method for separating tobacco or the like fibers moving on channeled trajectories.
  • the invention also relates to a device for separating tobacco fibers which have been converted by an acceleration means into trajectories delimited by channel walls.
  • similar fibers generally means fibers made of smokable material, for example also made of tobacco substitutes.
  • quality features relate to various product properties in a defined range of variation, such as the uniformity of the tobacco distribution in the cigarettes, weight fluctuations, filling power, hardness, fiber length and head quality of the cigarettes.
  • the quality features mentioned depend crucially, among other things, on the most complete separation possible, even distribution and filling of the tobacco fibers in the so-called distributor of the cigarette machine.
  • the tobacco fibers are shortened in an undesirable manner due to the sometimes very rough mechanical effects on the tobacco.
  • the invention is based, to take measures for a gentle tobacco separation of the tobacco fibers the task.
  • the tobacco fibers are acted upon alternately from opposite sides along their trajectory by blowing air guided essentially transversely to the direction of movement or with a component in the direction of movement of the tobacco fibers.
  • air guided essentially transversely to the direction of movement or with a component in the direction of movement of the tobacco fibers By alternately blowing such a tobacco shower, the tobacco fibers are deflected several times from their main direction of movement, the faster lateral air flow loosening clumps and separating the tobacco fibers.
  • an optimal dissolving and separating effect is achieved in that the tobacco fibers are acted upon by the blown air at alternately offset locations on the sides delimiting the trajectories.
  • the trajectories expediently extend in the substantially vertical direction of fall of the tobacco fibers.
  • the device for carrying out the method described at the outset is formed by blowing air openings which alternately emerge along the trajectory of the tobacco fibers on opposite channel walls and are oriented essentially transversely to the trajectory or with a component in the direction of flight of the tobacco fibers. In this way, a targeted, concentrated, rapid blown air flow can be directed towards the tobacco shower flying past, which is thus alternately deflected against the opposite channel walls and thereby fanned out or detached and separated with respect to its fibers.
  • the blown air openings are arranged on alternately opposite parts of the duct walls.
  • the blown air openings can be designed in different ways within the meaning of the invention, for example designed as rows of holes. According to a preferred embodiment of the invention, the blown air openings are designed as slots which extend over the width of the channel walls.
  • the blown air deflection according to the invention can advantageously be integrated into a conventional distributor of a cigarette machine in which the channel walls delimit a substantially vertical chute for the tobacco fibers.
  • the blown air openings can best be realized according to one embodiment in that the blown air openings are assigned to nozzle boxes integrated in the channel walls.
  • the trajectories of the tobacco fibers required as a prerequisite for the lateral blowing air can best be achieved, according to an additional proposal, in that the accelerating means is a rotating beater roller which interacts with a tobacco discharging roller from a storage chute.
  • the chute opens on the underside of a tobacco fibers through a cross-air flow into a sighting device that transports a strand building zone.
  • the advantage achieved by the invention is that the tobacco is deflected several times from its predetermined trajectory by the offset lateral blowing and thereby on gentle, Tobacco sparing way is isolated. In the end, this more isolated tobacco, which has retained its fiber length, results in a more even tobacco distribution, less weight fluctuations, greater hardness and a more uniform, better head quality of the cigarettes.
  • the figure shows schematically the distributor of a cigarette rod machine in longitudinal section.
  • the distributor which is only partially shown for an understanding of the invention, has a storage chute 1 with a tobacco supply 2 and a removal device 3, which consists of a removal roller 4 and a beater roller 6.
  • the shower 7 of tobacco fibers which is removed from the storage shaft 1 by the removal device 3, enters a funnel-shaped drop shaft 8, on the underside of which a viewing device 9 forming a presifter through blowing air nozzles 12 associated with a cross-air flow from a pressure chamber 11 the tobacco fibers emerging from the drop shaft 8 transferred a strand build-up zone described below.
  • the transverse air flow separates lighter tobacco fibers 13 from heavier tobacco fibers 14 (tobacco ribs) and conveys them in the direction of arrow 16 to the strand building zone.
  • Some lighter tobacco fibers 13 sink down with the heavier tobacco ribs 14. You get through a rotary valve 17 into a viewing shaft 18, in which the heavier tobacco ribs 14 sink further down and are discharged, while the lighter tobacco fibers 13 rise due to the injector effect of a blast air jet from a nozzle 19 forming a re-sifter and into the stream of lighter fibers 13 are returned.
  • the tobacco fibers With the support of further blowing air nozzles 21 of a pressure chamber 22 the tobacco fibers are transferred to a guideway in the form of a guide surface 23, on which they are built up into a tobacco stream 24 of loosened and spreading tobacco fibers, blown air and tobacco particles forming a wall flow moving closely along the guide surface 23.
  • the loosened and spreading tobacco stream 24 arrives in a strand build-up zone 28 to a suction strand conveyor 29, to which a suction pull for forming and holding a tobacco strand is applied from the rear by the suction effect of a vacuum chamber 31. Excess blown air escapes through a sieve 32 into a relaxation space 33.
  • the suction line conveyor 29 rotates in a tobacco channel 34 which is laterally delimited by two channel cheeks 36 and 37.
  • the end section 23a of the guide surface 23 is aligned with one of the channel cheeks 36, so that a seamless, smooth transition of the guide surface to the tobacco channel 34 is ensured.
  • the end section 23a of the guide surface 23 is designed as a guide body 39 which can be pivoted about a pivot axis 38 in order to ensure better accessibility of the device in the event of faults.
  • the beater roller 6 knocking the tobacco out of the removal roller 4 serves as an accelerating means for the tobacco shower 7, which in this way is converted into a downward main trajectory (arrow 41).
  • the chute 8 is delimited by opposite, downwardly converging duct walls 42 and 43, into the alternately offset blowing air openings in the form of slots 44 and 46 extending across the width of the duct walls (perpendicular to the plane of the drawing) are let in.
  • the slots 44 and 46 are aligned essentially transversely or with a slight component in the direction of the flight path 41 of the tobacco shower 7.
  • the slots 44 and 46 are fed with blown air from nozzle boxes 47 and 48 arranged on the rear of the channel walls 42 and 43. Due to the alternately against the downwardly thrown tobacco shower 7 essentially transverse air flow from the slots 44 and 46, the tobacco shower 7 is alternately deflected from its main trajectory 41 and the tobacco fibers contained therein detached from one another, so that at the exit of the chute 8 a largely loosened tobacco shower 7 is transferred to the viewing device 9.
