Definitions

  • the invention relates to a device and a method for removing long-fiber foreign matter from tobacco before its further processing into cigarettes.
  • the tobacco to be processed in a cigarette machine can contain foreign bodies and foreign substances that must not get into the cigarette machine, in spite of the necessary care during harvesting and shipping by the manufacturer, in order to prevent damage to the machine and negative effects on the quality of the cigarettes.
  • Granular foreign bodies such as metal parts, which differ significantly from tobacco in terms of their shape and weight, can be removed relatively easily using suitable detectors.
  • fibrous components which have a consistency similar to that of tobacco pose considerable problems. This applies in particular to fibers that occasionally detach from the jute bags used to ship the tobacco and get into the tobacco. Such fibers differ from the tobacco particles practically only by their greater length.
  • a cleaning device is known from EP 046 63 49 with which pollutants and other substances are removed from the tobacco.
  • This cleaning device has comb rollers on which the substance to be cleaned is applied.
  • the comb rollers are provided with a layer with small hooks protruding radially outwards.
  • This layer consists of the material known under the trade name "Velcro”. Pollutants that are present in the tobacco get caught on the above hooks of this layer, so that these foreign bodies circulate with the comb rollers.
  • the comb rollers must therefore be cleaned of foreign bodies at regular intervals.
  • a disadvantage of the device shown is the low cleaning effect of the "Velcro" layer, since the above hooks are elastic, so that heavier foreign bodies are poorly carried away by this layer. Furthermore, the cleaning layer has to be laboriously cleaned or replaced if it is clogged with foreign bodies.
  • the invention has for its object to provide a device by means of which long-fiber foreign substances can be removed from the tobacco intended for processing in a cigarette machine.
  • the degree of cleaning is to be improved compared to known devices and a simple possibility for cleaning the cleaning agents is to be created.
  • the device according to the invention has a plurality of rollers arranged parallel to one another, which are provided on their outer circumference with a plurality of radially outwardly directed needles and rotate in the same direction of rotation.
  • the overhead circumferential surfaces of the rollers thereby move essentially in the same direction and move the one on the rearmost roller in this direction of movement added tobacco one by one to the foremost roller. Small tobacco particles that fall between the rollers are caught underneath and added to the rest of the tobacco.
  • All needles advantageously have the same length of 5 to 30 mm, preferably 10 mm, and a mutual distance of 1.5 to 15 mm, preferably 3 mm.
  • the gap between the tips of the needles of two adjacent rolls is 0.0 to 80 mm, preferably 50 mm wide, with an outside diameter of the rolls of 150 to 300 mm, preferably 200 mm.
  • the rollers can be arranged in a housing which is open at the top and lie next to one another at the same height. However, it is also possible to arrange them inclined with respect to the horizontal, so that there is a slight slope in the direction of the tobacco being transported.
  • rollers which are alternately fed with the tobacco to be cleaned.
  • the rollers are provided with a scraper belt on their circumference.
  • a scratch tape is an elastic band from which diagonally arranged steel needles protrude. This scraper tape is easy to manufacture by passing a large number of staples through a tape with a textile layer and an elastic plastic layer. With the scraper belt, the rollers with the needles protruding outwards can be produced simply and cheaply by winding the scraper belt on cylindrical rollers.
  • a cleaning device which removes the foreign substances deposited between the needles. This eliminates the tedious manual cleaning of the rollers, so that no rollers have to be provided for replacement if the rollers are clogged with foreign bodies. Such a cleaning device shortens the cleaning process, with the rollers being cleaned very thoroughly.
  • the cleaning device preferably has at least one cleaning roller which is provided with knife disks.
  • a simple and thorough cleaning can be achieved if the needles are arranged in rows and the knife disks engage between two rows of needles. This also keeps wear to a minimum, since the individual needles are not damaged and the knife discs comb on the soft roller surface.
  • roller of the cleaning device While the roller of the cleaning device is driven in the circumferential direction, there is no separate drive in the axial direction. Rather, the feed is effected by the rotating, spirally arranged needles, which abut against the side surfaces of the cutter disks of the device and move the cleaning roller axially forward.
  • the device consists of a rectangular frame 1 with a support 2 arranged in its center, which supports a bottom 3.
  • the bottom 3 is rotatable about the axis of the support 2 and also inclined in the manner shown in FIG. 1 with respect to the horizontal.
  • two rectangular housings 4 are arranged side by side, consisting of a floor and four side walls, while the top is open.
  • each housing 4 seven rollers 5 are mounted side by side and axially parallel, each of which is driven by a common drive 6 in the same direction of rotation.
  • the direction of rotation is such that the tops of the adjacent rollers rotate against the direction of the slope, i.e. the rollers 5 indicated in Fig. 1 rotate clockwise.
  • the rollers 5 have a diameter of about 200 mm and are equipped with a large number of short needles 7 on their outer circumference, which protrude radially outwards.
  • the needles are all the same length with a length of approx. 10 mm and are close together.
  • the individual rollers are spaced apart from one another such that there is a distance of approximately 50 mm between the tips of opposing needles.
  • a feed for the tobacco to be processed opens in the form of a chute 8 on the right, while a discharge conveyor is provided on the right, which in the exemplary embodiment shown is designed as a conveyor belt 9.
  • a discharge conveyor is provided on the right, which in the exemplary embodiment shown is designed as a conveyor belt 9.
  • the housing 4 can also be arranged horizontally displaceably on a suitable guide.
  • the tobacco is continuously fed via the chute 8 onto the rollers 5, which rotate at high speed.
  • the short-fiber tobacco particles are taken from the top of the rollers with the needles and in this way pass from one roller to the adjacent one.
  • Smaller tobacco particles, which are more granular, occasionally pass through the narrow gap between the rollers and fall to the bottom of the housing 4 due to their own weight and the centrifugal force of the rollers. These particles are reunited with the fibrous tobacco particles at the outlet end of the housing 4.
  • the drive 6 is stopped briefly and the housing 4 which is in the waiting position is brought under the chute 9 by rotating the base 3 or moving the housing. Operation can then be resumed immediately.
  • the foreign substances are removed from the waiting rollers by suitable means.
  • FIG. 4 shows a further exemplary embodiment of the invention, in which a cleaning device 10 is provided.
  • the cleaning device 10 is located above a roller 5 and has two cleaning rollers 11 which are driven by a belt 13 and a drive unit 12.
  • the cleaning device 10 is movably supported on a guide rail 14 by two guides 15, so that it can be moved along the guide rail 14 in the axial direction.
  • the scraper belt consists of a textile layer that faces the roller 5 and an elastic plastic layer that is attached to the textile layer.
  • a large number of steel staples are passed through these two layers and are slightly inclined above the elastic plastic layer.
  • the tips of the staples form the needles 7.
  • the staples are arranged in rows, so that individual grooves 17 are formed between adjacent needles 7, which are spaced about 1.5 mm apart.
  • the surface at the end of the needle tips is perpendicular to the radial direction when the scraping tape is applied to the roller 5.
  • the inclination of the individual needles 7 results in different angles on the edge of this end on the surface of the end of the needles 7.
  • the cleaning rollers 11 have the same direction of rotation as the roller 5, so that knife disks 18 arranged on the cleaning rollers 11 and the roller 5 move in the opposite direction on the contact surface. Due to the spiral arrangement of the scraper belt and the grooves 17 formed by the individual needles 7, the entire cleaning device 10 is moved in the axial direction. A drive for the feed is not required.
  • the hardened knife disk 18 has a plurality of knife teeth 19, the circumferential angle of which is 15 ° on the knife disk 18.
  • Each knife tooth 19 has a cutting surface 20 on its front side.
  • the knife disk 18 is guided in the groove 17 formed by needles 7, the knife teeth 19 removing the foreign bodies from the groove 17.
  • the foreign bodies are entrained by the rotary movement of the cutter disk 18 in the direction of rotation of the cutter disk 18 and suctioned off through a suction pipe 21.
  • the suction pipe 21 has an attachment which is fixedly mounted on the cleaning device and thus follows every movement.
  • the diameter is about 80 mm.
  • the cutter disks 18 on the cleaning rollers 11 are offset from one another so that the cutter teeth 19 of the one cutter disk 18 are in contact with the roller 5 when there is a gap to the roller 5 in the adjacent cutter disk 18 due to a tooth gap. This ensures that the cleaning rollers 11 rest on the roller 5 without interruption.
  • the cleaning device 10 As soon as the cleaning device 10 has reached the edge region of a roller 5, the cleaning device is lifted off the roller 5 and placed on the next roller 5. On the next roller 5, the scraper belt is spirally wound in the opposite direction, so that the cleaning device 10 is guided from one end of the roller 5 to the other end of the roller 5 and a meandering cleaning pattern is thereby created.
  • the cleaning process is always carried out when no tobacco is transported over the rollers 5.
  • the cleaning device can be controlled automatically or manually.
  • the rotational speed of the roller 5 is reduced to approximately 15% of its normal rotational speed in order to be able to better grip and separate the foreign bodies on the roller 5.
  • the rotational speed of the cleaning roller 11 is approximately the same as the rotational speed of the rollers 5 during the cleaning process.
