With Separator For Tobacco Dust, Stems Or Foreign Material Patents (Class 131/109.2)
  • Patent number: 10791757
    Abstract: A plant material assembly for separating cannabis plant material is provided having a plant material hopper configured to receive the cannabis plant material and feed the cannabis plant material to a plant material separator. The plant material separator is configured to separate undesirable plant material from desirable plant material by using a first roller, a second roller, and a third roller. The first roller and the second roller separating the cannabis plant material into the desirable plant material and the undesirable plant material by sending the desirable plant material in a first directional path and the undesirable plant material in a second directional path. Next, the third roller is used in relation to the first roller and the second roller, wherein the third roller redirects the undesirable plant material from the second directional path into a third directional path and finally into a catch depository.

  • Patent number: 7802578
    Abstract: A shredded tobacco supply device for a cigarette manufacturing machine includes a separation throat (20) diverging from a gravity chute (18) through which shredded tobacco is let fall down, and an extension (68) extending from the outlet (20b) of the separation throat (20) and forming an air confluent nozzle (69) in cooperation with the trough bottom (38) of a fluid bed trough (36). The air confluent nozzle (69) produces a transport flow by joining together primary and secondary air jets J1 and J2 used for winnowing the shredded tobacco, and the transport flow causes a shred mixture obtained by the winnowing to be conveyed along a conveyance surface (38) toward a tobacco band.

  • Patent number: 7584758
    Abstract: A distributor or hopper is part of a cigarette production machine and serves for dressing the tobacco in the provision of a continuous tobacco strand. An integral part of a distributor is a metering system which prepares the tobacco for the production of the tobacco strand. To separate out undesirable constituents, such as foreign bodies, stalks or ribs, from the tobacco, at least one sifter (15) is provided. The latter precedes the metering system of the distributor in the working direction, in particular is arranged outside the distributor, so that sifted tobacco is introduced into the distributor.

  • Patent number: 6877515
    Abstract: Apparatus for making one or more rod-like fillers of shredded tobacco for use in the making of cigarettes or the like employs one or two pneumatic conveyors having endless foraminous belts trained over pulleys and including elongated stretches below communicating parts of a common suction chamber. A shower of intermixed tobacco shreds and smaller particles including tobacco dust and coarser particles is directed against the undersides of the elongated stretches. The shreds are attracted to and advance with the respective belts to form streams which are ready to be trimmed and thereupon draped into cigarette paper or the like. At least some smaller particles penetrate through the respective belts into the corresponding parts of the suction chamber. The contents of the suction chamber are evacuated by suction and are returned to the undersides of the elongated stretches of the belts for classification.

  • Patent number: 6768317
    Abstract: A method of detecting impurities in a mass, such as detecting metallic and/or plastic particles in a stream of tobacco particles or filter material for tobacco smoke, includes the steps of moving the mass relative to a microwave field and/or vice versa, and analyzing the influence of the mass upon the microwave field. The analyzing step involves simultaneously measur- the actual values of a first and a second parameter of the microwave field, ascertaining the presence or absence of those changes of the parameters which are attributable to the presence of impurities in the mass, determining whether or not the changes are within an acceptable range, and generating signals for segregation of impurities-containing portions of the mass from the other portions when the changes are outside of the acceptable range.

  • Patent number: 6371125
    Abstract: Apparatus for transporting rod-shaped tobacco smoke filters which contain and/or carry particles of charcoal and/or other solid particulate tobacco smoke filtering and/or flavoring material. A sender directs a series of successive filters lengthwise into a pneumatic conduit wherein the filters advance toward a receiving station. A section of the conduit has an arcuate shape and advances successive filters from a lower level to a higher level. The underside of the section has an elongated arcuate opening which is overlapped by a cover in such a way that any solid particles which became separated from the filters can be expelled into a neighboring chamber due to fluid pressure in the section as well as under the action of gravity and/or centrifugal force.

  • Publication number: 20010052346
    Abstract: A hopper is connected with a machine for manufacture of tobacco industry products including a tangential separator sequentially feeding an entry stock of the hopper. The distribution between portions of tobacco streams including a large proportion of short tobacco fibers and portions including a large proportion of long tobacco fibers of the tobacco stream set apart in advance in the entry stock is essentially longitudinal when the stream arrives on a transfer belt of the hopper. By imposing a change of direction on the tobacco stream as well as a reduction of speed of displacement of this stream, this longitudinal distribution is transformed into a transverse distribution. A spiked or barbed roller, placed at a right angle to this latter stream, homogenizes the distribution, making it possible for the distribution to be regular between short fibers and long fibers in the tobacco stream arriving through the chimney for the manufacture of the tobacco rod.
