Definitions

  • Separating device for separating tobacco fibers flowing through a flow path
  • the application relates to a separating device for separating tobacco fibers flowing through a flow path, with at least one rotatably driven Ver ⁇ einzelungswalze.
  • EP 0 895 721 B1 discloses a conditioning device with a rotating Winnover roller which is acted upon by a conditioning medium. From DE 100 08 961 Al a separating device with a pair of cooperating, in the same direction rotating rake is known, which are acted upon by air and Heildü ⁇ sen for generating blast air jets. To solve clumped or intertwined tobacco, a further improvement of the singulation effect is desired.
  • EP 0 410 682 B1 and US Pat. No. 4,867,180 disclose a tobacco feed device for a cigarette production machine, in which jammed tobacco is removed from a stowage shaft by means of two metering rollers and is separated and separated by means of an opening roller. The tobacco is compressed between the metering rollers, whereby the fiber structure of the tobacco can be destroyed by mechanical force.
  • the object of the present invention is to provide a separating device with improved separating effect.
  • the separating device has at least three rotatably driven separating pulleys which are operatively connected and which are designed and arranged in such a way that the tobacco fibers release the pulp rotating separating rollers pass substantially congestion.
  • the forces exerted on the tobacco by the separating rollers are directed differently, whereby the tobacco fibers are subjected to shearing forces which, on the one hand, hold the tobacco and on the other hand remove it, thereby leading to an effective separation of the tobacco fibers.
  • the tobacco fibers pass through the separating rollers substantially without jamming, so they are not dammed up and combed off in order to avoid a mechanical impairment of the tobacco fibers due to a compression of the accumulated tobacco between the separating rollers.
  • This can be achieved, in particular, by a suitable spacing of the separating rollers from one another and / or by a suitable number, arrangement and length of separating elements, for example pins, attached to the separating rollers.
  • the passage speed of the tobacco through the separating device is determined primarily by the free flow rate of the tobacco in the flow path, and less by the rotational speed of the separating rollers.
  • the separating device can in particular be designed so that the flowing tobacco can pass through the separating device even with stationary separating rollers substantially free of congestion, at least at low tobacco mass flow.
  • At least one of the separating rollers on outlet openings for a medium, in particular air, steam or a mixture thereof.
  • a medium in particular air, steam or a mixture thereof.
  • the separating rollers are driven individually in order to be able to individually adjust the rotational speed and / or direction of rotation of the separating rollers in a simple manner.
  • the following features are preferably realized alternatively or in combination: opposite directions of rotation of the separating rollers; differently designed nozzles for the medium; different surface conditions of the separating rollers and / or separating elements attached thereto, for example pens.
  • the rotational speeds of the separating rollers can be individually adjusted according to the requirements or the type of tobacco.
  • the separating rollers are arranged on a common, adjustable carrier in order to make it possible to adapt to the respective requirements or the respective type of tobacco by adjusting the carrier relative to the flow path.
  • the carrier may be rotatably mounted. It can also be provided that the carrier is rotated by means of a rotary drive, in order thereby to achieve an improvement in the singling effect.
  • steam in particular saturated steam
  • conditioning in particular expansion, of the tobacco
  • FIG. 1 shows a schematic sketch of a flow path for the tobacco feed with a separating device
  • FIG. 2 is a perspective view of a separating device
  • FIG. 3 shows a further perspective view of the separating device from FIG. 2;
  • FIG. 4 shows a plan view of the separating device from FIG. 2 from above;
  • FIG. 5 a side view of the separating device from FIG. 2; FIG.
  • FIG. 6 a front view of the separating device from FIG. 2; FIG. and
  • FIG. 7 shows a further side view of the separating device opposite to the view according to FIG. 6.
  • FIG. FIG. 1 shows an application of a separating device before a tobacco inlet opening for a downstream pneumatic dryer or current dryer.
  • the singling device can also be used, for example, for feeding tobacco into a pneumatic conveying system, a pneumatic conveying or charging, a fluidized bed conveyor (dryer, cooler, classifier) or a cross-flow view.
  • a delivery assembly 10 includes a tubular housing 11 through which tobacco material 12 flows in the direction of the arrow of Fig. 1.
  • a separating device 16 is arranged, which comprises a plurality of separating rollers 13 to 15 for separating the tobacco material 12 flowing through the chamber 11.
  • the tobacco is fed through a tobacco inlet in the form of a rotary feeder 20 into the part of the housing 11 assigned to the separating device 16.
  • the supply can generally also be effected, for example, by means of a channel, a conveyor belt or another conveying element.
  • the tobacco material 12 enters through the outlet opening 17 into a drying tube 18, through which a hot gas stream 19 flows, of a current dryer.
  • the hot gas stream 19 receives the incoming tobacco material 12 and transports it in the direction of arrow through the drying tube 18th
  • the separating device 16 comprises in the embodiment of FIGS. 2 to 7, three separating rollers 13-15.
  • the separating rollers 13-15 each comprise a roller body 23-25 and thereon arranged separating elements 33-35.
  • the separating elements 33-35 preferably extend radially with respect to the roll body 23-25.
  • a separating roller 13 in the form of a raking rollers with pins 33 and two separating rollers 14, 15 in the form of spiked rollers with spikes or pins 34, 35 are provided.
  • the invention um ⁇ summarizes any combination of computing rollers and / or spiked rollers or other rollers with differently shaped separating elements.
  • the separating elements 33-35 can be rotatable about their own longitudinal axis, for example by using rotating internals or a vapor or air-flowed wing structure, and thereby pulsating the medium onto the tobacco in order thereby to submerge Circumstances to achieve an improvement of the singulation effect.
  • At the pins 33 of the arithmetic roller 13 may additionally be arranged spikes or pins.
  • the separating rollers 13-15 are arranged at a sufficient distance from each other to allow a substantially free or jam-free fall of the tobacco by the separating device 16. This applies in the case of rotating separating rollers 13-15 and preferably also in stationary separating rollers 13-15, if the tobacco mass flow is not too high.
  • the separating elements 33-35 of different separating rollers 13-15 are preferably arranged without overlapping.
  • the distance of the separating rollers 13-15 is preferably adjustable, for example by means of corresponding guides 48, to allow adaptation to changing conditions or different types of tobacco.
  • the separating rollers 13-15 are preferably arranged not in a line but offset from one another in several planes, in order to achieve an improved cooperation.
  • the longitudinal or rotational axes of the separating rollers 13-15 are preferably arranged parallel to one another.
  • the separating rollers 13-15 are mounted rotatably about their longitudinal axis by means of corresponding bearings 26-28 and are driven in rotation by corresponding individual drives 43-45, for example via corresponding toothed belts 53-55.
