Definitions

  • the invention relates to a device for conveying and processing tobacco - fibers made of smokable material - in connection with the formation of a tobacco rod for the production of cigarettes, the tobacco being able to be fed to a distributor - hopper.
  • tobacco in this case includes all types of fibers made of smokable material, but also fibers for the manufacture of cigarette filters.
  • a continuous tobacco rod is usually formed for the manufacture of cigarettes, which is surrounded by cigarette paper.
  • the manufacture of the tobacco rod requires careful preparation of the tobacco or the tobacco fibers.
  • the tobacco in the area of the tobacco rod should be free of foreign bodies. When preparing the tobacco, it is important that on the one hand tobacco lumps are avoided or eliminated, and on the other hand that the tobacco fibers are not crushed too much.
  • the invention has for its object to propose measures for a powerful, in particular mechanical processing of tobacco (tobacco fibers), through which the tobacco is optimally treated.
  • the device according to the invention is characterized by the following features:
  • the distributor forms a closed tobacco room within a housing, preferably in the upper region,
  • a rotatingly driven conveying and loosening element for tobacco is mounted, namely a tobacco roller having a driver.
  • a tobacco room is therefore formed in the upper region of the closed distributor, in which negative pressure prevails due to the suction of air.
  • This also promotes tobacco in the tobacco room.
  • the tobacco roller is special because it is driven at a relatively high speed and by special Trained carriers dissolve or loosen the tobacco while removing lumps of tobacco.
  • the tobacco roller which acts as a tobacco conveyor, transfers the tobacco to a discharge wheel, which transfers the tobacco from the negative pressure area to an area below with normal pressure, namely a transverse tobacco conveyor, which, due to its mode of operation, removes foreign objects with a higher weight.
  • a special feature of the invention is the feeding of the tobacco above the tobacco roller into the tobacco room, with simultaneous transverse distribution.
  • a lower boundary of the tobacco space is designed as a conveyor which transports the tobacco to the circumference of the tobacco roller.
  • FIG. 1 shows a device for treating tobacco in side view or in vertical section of the overall device
  • FIG. 2 shows the upper area of the device according to FIG. 1 on an enlarged scale
  • FIG. 3 shows a detail of the device in a sectional plane III-III of FIG. 2, on a further enlarged scale
  • FIG. 5 shows the detail according to FIG. 4 in a view corresponding to V-V of FIG. 4,
  • FIG. 6 shows a horizontal section essentially of a tobacco drum in the section plane VI-VI of FIG. 2,
  • Fig. 7 is an illustration analogous to FIG. 2 for another embodiment of the device according to the invention.
  • the manufacture of cigarettes also requires careful mechanical processing of the tobacco.
  • the tobacco is introduced into a treatment device, namely into a distributor - hopper - which is surrounded by a housing 10.
  • the tobacco is introduced laterally as tobacco flow 12 into the distributor in the upper region, namely immediately below an upper wall 11.
  • the tobacco stream 12 enters into a tobacco chamber 13 formed in the upper region by suction, that is to say due to negative pressure.
  • Within this tobacco room 13 there is a tobacco conveyor which, in the embodiment according to FIGS. 1 to 6, is designed as a screen roller 14 with a transverse axis of rotation.
  • the tobacco is fed into the tobacco room 13 above the tobacco conveyor or above the screen roller 14.
  • Light tobacco i.e. tobacco parts with a low dead weight, falls from above onto the screen roller 14, namely onto the roller jacket 15 16 of the tobacco room 13.
  • the tobacco room 13 is delimited at the bottom by a chamber wall 17 arranged in a special way within the housing 10.
  • the chamber wall 17 is inclined downwards in the direction of the screen roller 14.
  • the chamber wall 17 continues as an arcuate area, with adaptation and nestling to the circumference of the screen roller 14.
  • the chamber wall 17 extends to the area of a subsequent conveyor, namely a rotary valve 18.
  • the tobacco which is not deposited directly on the screen roller 14 is guided or moved in the direction of the screen roller 14.
  • tobacco is continuously taken up by the screen roller 14, which for this purpose is along the circumference. distributed drivers.
  • the tobacco or tobacco stream 12 is introduced into the device in a special way, namely by distributing the tobacco in the transverse direction, that is to say parallel to the axis of rotation of the screen roller 14.
  • the tobacco stream 12 is fed through a tubular tobacco channel 19 which is above the screen roller 14 in the housing 10 opens with a horizontal leg.
  • a movable steering member for the tobacco stream 12 is attached.
  • a special feature is the design and mode of operation of the screen roller 14.
  • This is equipped with an air-permeable roller jacket 15.
  • the roller jacket 15 consists of a grid of longitudinal webs 23 and circumferential webs 24. These together form a lattice-shaped structure with (rectangular) openings. Fine-meshed sieves 25 are attached within the openings.
  • the screen roller 14 is rotatably mounted in or on the housing 10 via end walls 26, 27.
  • a vacuum is generated in the interior of the hollow screen roller 14, by means of which the tobacco is held on the circumference or on the roller jacket 15.
  • the screen roller 14 is supported on one side with a hollow shaft 28 in the housing wall.
  • a suction element is connected to the screen roller 14, namely a suction tube 29.
  • This only enters the screen roller 14 as a pipe socket and generates negative pressure within the same, which is passed on to the tobacco chamber 13 via the air-permeable roller jacket 15. Accordingly, there is also negative pressure in the tobacco room 13, which also causes the tobacco to be supplied via the tobacco channel 19.
  • drivers are attached to the outside of the roller shell. These are a plurality of driver webs 30 arranged at a circumferential distance from one another. These extend in the direction parallel to the axis and are directed at an acute angle to the roller jacket 15, to be precise with the formation of hook-like drivers in profile.
  • the driver Crosspieces 30 are attached to support profiles 31 running in the longitudinal direction of the roll shell 15.
  • the carrier webs 30 are formed with a profile which brings about the comminution or dissolution of tobacco lumps, namely in the present case with a sawtooth profile 32.
  • the carrier web 30 thus produces a combing effect when the carrier webs 30 are moved one after the other from a lower region into the through the rotary movement of the screen roller 14 accumulated stock of tobacco.
  • tobacco portions 33 formed in the longitudinal direction of the screen roller 14 are taken along by the carrier webs 30.
  • the screen roller 14 thus also serves as a conveyor for the tobacco within the tobacco room 13, the tobacco being transported up to 180 ° and more.
  • the tobacco or the tobacco portions 33 are removed from the roller jacket 15 during a downward movement.
  • the tobacco portions 33 essentially reach the area of the cellular wheel sluice 18 in free fall, which transports the tobacco further and thereby delimits a subsequent area with normal pressure from the negative pressure area in the upper part of the housing 10.
  • a rotatable separating member 34 is effective adjacent to the roller jacket 15. This has rotating organs that enter the tobacco or tobacco portions 33.
  • a plurality of transversely projecting fingers 36 are arranged on a rotatable tube 35, namely in two approximately radially projecting rows. These fingers 36 enter the tobacco as a result of the rotational movement of the singling member 34, loosen it or separate clumps and convey the tobacco treated in this way towards the cellular wheel lock 18.
  • the singling member 34 rotates at high speed, at least significantly higher than the speed of rotation of the screen roller 14.
  • the direction of rotation of the separating member 34 is opposite to that of the screen roller 14.
  • a stationary blowing member namely an elongated, slit-shaped blowing nozzle 37
  • the blow pipe 38 enters the suction pipe 29, which has a correspondingly larger diameter, and runs centrally within the suction pipe 29.
  • the blow nozzle 37 which extends approximately over the full length of the screen roller 14, directly adjoins the blow pipe.
  • An opening of the blowing nozzle 37 is in the immediate vicinity of the roller jacket 15, specifically in the region of the tobacco discharge, namely opposite the separating member 34.
  • the blowing member or the blowing nozzle 37 is thus also a cleaning member for the screen roller 14.
  • the loosened and unclumped tobacco is conveyed downward from the rotary valve 18 and placed on a connecting conveyor.
  • the connection conveyor is designed here as a vibrating conveyor, namely as a vibrating conveyor trough 40. This extends from a region below the cellular wheel sluice 18 with a slight incline upwards to the opposite side of the device or the housing 10. There the tobacco is processed.
  • the vibrating conveyor trough 40 is driven to vibrate for conveyance. As a result, the (light) tobacco is moved upward, while heavy foreign bodies 39 are moved downward against the conveying direction by their own weight and thereby fall into a collecting container 41.
  • the negative pressure prevailing in the entire tobacco room 13 up to the cellular wheel sluice 18 is generated according to FIGS. 1 to 6 via the screen roller 14 or the suction pipe 29, which emerges from the housing at the top in the region of the upper wall 11.
  • Normal pressure prevails in the housing 10 in the area outside the tobacco room 13.
  • ventilation takes place via a suction pipe or ventilation pipe 42, which likewise emerges from the housing 10 in the upper area.
  • a special feature is the overall design of the device according to FIG. 1.
  • the unit described for distributing the tobacco and for loosening it is located in an upper region of the very compact housing 10.
  • organs and units are arranged which feed the tobacco transported by the vibrating conveyor trough 40 to a suction belt 43 which forms within a suction channel 44 and forms tobacco flows in channels.
  • a tobacco rod is formed on the underside of a lower strand of the suction belt 43 as part of a cigarette rod for the manufacture of the cigarettes.
  • the upper area of the housing 10 is therefore delimited by the chamber wall 17 from the lower part, in which normal pressure prevails.
  • negative pressure or positive pressure is generated in the channels.
  • the entire device is thus housed in a clear formation within the compact housing 10.
  • the embodiment according to FIG. 7 largely corresponds to the example described above, so that the same reference numbers are used for the same objects.
  • the negative pressure in the tobacco room 13 is generated here in a different way, at least not via the tobacco conveyor. Rather, air is extracted directly from the tobacco room 13.
  • a suction pipe 45 is attached in the area of an upper wall 11 of the housing 10. This leads directly into the tobacco room 13, namely adjacent or above the mouth of the tobacco channel 19.
  • the suction pipe 45 has a sieve insert 50.
  • the tobacco conveyor is designed as a closed hollow body, namely as a tobacco roller 46.
  • This has a closed cylindrical jacket 47, on the circumference of which the drivers or driver webs 30 are attached in the embodiment described.
  • the tobacco roller 46 is driven to rotate in the direction of the arrow.
  • a further special feature is a conveying aid for feeding the tobacco in the tobacco room 13 to the circumference of the tobacco roller 46.
  • a tobacco conveyor is provided as the lower boundary of the tobacco room 13 or as part of the chamber wall 17, a conveyor belt 48 in the exemplary embodiment shown 49 forms the boundary of the tobacco room 13 in this area.
  • the conveyor belt 48 is directed obliquely downwards, namely approximately tangentially to the tobacco roller 46.
  • the conveyor belt 48 reliably feeds the tobacco in the tobacco chamber 13 to the circumference of the tobacco roller 46 in the lower region thereof. Areas of the chamber wall 17 seal against the conveyor belt 48.
