Definitions

  • the invention relates to a method of forming a tobacco rod for the manufacture of rod-shaped articles of the tobacco processing industry, wherein a particulate-enriched stream is separated from a particulate tobacco fiber stream for the tobacco rod and the tobacco fiber stream is fed to the particles of lean tobacco fiber stream.
  • the invention relates to a device for forming a tobacco rod for producing rod-shaped articles of the tobacco processing industry with a Tabakstrangsente issued and a feeder of a tobacco fiber stream to tobacco rod forming device and a separator for particles from the tobacco fiber stream.
  • a tobacco stream or tobacco rod is formed.
  • the tobacco supply must be made as uniform as possible to form the tobacco rod.
  • working with an excess of tobacco Under a Saugstrangadder the tobacco rod is aufauert and wrapped after leveling. Subsequently, the wrapped tobacco rod is cut into individual articles or tobacco sticks.
  • the tobacco used to form the tobacco rod can be roughly subdivided into short tobacco or other tobacco fibers, for example, medium and long tobacco fibers.
  • Short tobacco occurs in all processing steps of the manufacture of such articles.
  • the longer tobacco fibers provide the structural stability of the article, while the short tobacco contributes little to this.
  • a stream of tobacco is conveyed to a separation unit to separate the light, usable tobacco fibers and particles from the heavy, woody particles consisting primarily of the ribs of the tobacco leaves.
  • the heavy particles fall into a waste channel while the light tobacco fibers are fed by vacuum into a vertical channel closed at its tip by a suction conveyor onto which the light tobacco fibers are deposited to form a tobacco layer from which a continuous tobacco rod is formed ,
  • This object is achieved in a method for forming a tobacco rod for the production of rod-shaped articles of the tobacco-processing industry, wherein a particle-enriched stream is separated from a particle-laden tobacco fiber stream for the tobacco rod and the particle tobacco fiber stream is fed to the tobacco rod strand, the proportion of particles enriched in the particle is detected and that the separation process of the particles from the tobacco fiber stream is regulated as a function of the particle fraction in the particle-enriched stream.
  • the tobacco fiber stream is pre-sized.
  • the tobacco fiber stream is regulated as a function of the deviation of the actual value of the particle fraction in the particle-enriched stream from a, preferably predefinable, desired value.
  • the ratio of the particle fraction density in the particle-enriched stream to the tobacco fiber stream density in the particle-lean tobacco fiber stream is kept constant.
  • the particle fraction is detected by means of a gravimetric or optical measuring device.
  • gravimetric measuring devices weighing scales, belt scales or baffles are known.
  • An optical measuring device is known, for example, DE-C-199 48 559.
  • the particle fraction is detected by means of a microwave measuring device. This has the advantage that in addition to the excluded or separated Particles, in particular ribs, and foreign bodies are detected and discharged.
  • the detection of the particle fraction and the control of the tobacco fiber stream is carried out continuously.
  • the tobacco fiber stream is controlled by means of a prepare for delivery.
  • tobacco ribs are precipitated as particles from the supplied tobacco fiber stream.
  • a device for forming a tobacco rod for producing rod-shaped articles of the tobacco processing industry with a Tabakstrangsente coupled and a feeder of a tobacco fiber stream to Tabakstrangsente interests and a separator for particles from the tobacco fiber stream further developed by the fact that a measuring device for detecting the proportion of particles in the Particle enriched stream and that a control device are provided for controlling the tobacco fiber stream.
  • a tobacco fiber stream caulking device is provided to remove long tobacco fibers from the tobacco fiber stream conveyed to the separator.
  • the tobacco fiber stream density can preferably be regulated as a function of the particle fraction in the particle-enriched stream.
  • control device is a comparison device for comparing an actual value of the particle fraction with a, preferably predetermined, setpoint, so that the degree of separation of the particles is kept constant from the tobacco fiber stream.
  • the target value is determined and entered before the start of production for the processed tobacco mixture.
  • the measuring device is designed as a gravimetric or optical measuring device.
  • the measuring device is designed as a microwave measuring device.
  • Fig. 1 the principle of the deposition of a particle flow from an output stream according to the prior art is shown in a schematic diagram.
  • a tobacco fiber stream 110 with particles consisting of tobacco fibers and tobacco ribs and other constituents is placed on a sifter 120.
  • Tobacco ribs and other particles are separated off from the tobacco fiber stream 110 by means of the classifier 120 in a separation stream 140.
  • the unseeded tobacco fibers as well as other ingredients are supplied as tobacco fiber stream 130 to the tobacco mat as well as the tobacco rod to be formed.
  • Via an actuator 125 the degree of separation of the tobacco ribs and the other heavier components or foreign bodies on the separator 120 is adjusted manually by operating personnel.
  • the degree of separation is determined manually and remains unchanged during the production of a tobacco rod in a certain tobacco mixture.
  • an embodiment of an inventive control of the tobacco fiber stream is shown in a schematic diagram.
  • a measuring device 145 the proportion of the tobacco ribs and other particles in the separation stream 140 is determined and forwarded as an actual value to a control device 150. Since the proportions of the particles or of the tobacco ribs in the tobacco fiber stream 110 also change when the tobacco mixture changes, a desired value SW for the degree of separation of the tobacco ribs or particles on the classifier 120 is likewise input to the regulating device 150. Depending on the difference between the common actual value and the target value SW, a signal becomes too large a deviation the actual value of the target value SW is given to an actuator 155, so that the deposition of the tobacco ribs and other components from the tobacco fiber stream 110 is changed and adjusted during operation.
  • the actuator 155 shown in Fig. 2 is realized for example by a servo motor.
  • Fig. 3 shows a schematic cross-sectional view of a fluidized bed distributor of a cigarette manufacturing machine not shown here for supplying tobacco to a suction belt conveyor 70.
  • the distributor is shown in fragmentary form in the right part of FIG.
  • a vibrating trough 4 or vibrating conveyor trough with a measuring device according to the invention is shown in a side view.
  • the vibrating conveyor trough is also shown in the right part of the figure in the lower region in longitudinal cross-section.
  • the cautioner 13 is provided with a caution nozzle and produces a substantially horizontal air flow.
  • the air flow directed transversely to the direction of fall of the tobacco separates lighter tobacco fibers from heavier ribs and promotes the lighter tobacco fibers on a guide surface 14 to form a tobacco mat.
  • the heavier tobacco components with the tobacco ribs fall as a separated partial flow T2 in a cell roller 15 and are added in portions in a Nachsichter 16.
  • a (not shown here) throttle blown air and the tobacco ribs / amount of tobacco is affected, which reaches the Nachsichter 16. Too large amount of tobacco / ribs can lead to clogging of the cell roller lock 15.
  • the separated partial flow T2 is fed to a in the Nachsichtschacht 17 directed vertically upwards classifying air flow. This results in a largely clean separation of the tobacco fiber stream (see Fig. 2, reference numeral 110) between the tobacco fibers and the tobacco ribs.
  • the tobacco fibers from the tobacco substream T2 together with the fibers from the caustic stream, enter the tobacco rod.
  • the heavier fins and particles in the post-sifter 16 fall as a particle enriched stream on a vibrating conveyor trough 4 and are conveyed out of the distributor area.
  • the vibrating conveyor trough 4 transports the trapped tobacco ribs R to a collecting funnel 9.
  • the tobacco ribs R enter the measuring area of a measuring device 8.
  • the measuring device is designed as a microwave sensor, so that the portion of the tobacco ribs and other foreign bodies are detected in the microwave field. By means of the microwave measuring device 8, the density of the tobacco ribs in the conveyed particles enriched stream is determined.
  • the ribs R contained in the particle stream slide over the sensor surface of the microwave measuring device 8 onto the bottom of the collecting funnel 9.
  • the particle stream is sucked off via a connected pipeline 7 and led to a collecting point.
  • the microwave measuring device 8 is associated with a signal processing electronics 18, which generates a signal for the rib mass flow and forwards it to a controller 19.
  • the controller 19 compares the actual value with an input target value SW and controls a servomotor 20 in the event of deviations.
  • the servomotor 20 may be, for example, a linear motor.
  • the servomotor 20 moves a linkage 21 due to the received signal from the regulator 19, so that the distance between the movable front sifter wall of the indenter 16 and the fixed sifter back wall is increased or decreased. As a result, the speed of the classifying air or blown air and thus the rib discharge from the supplied partial flow T2 change.
  • the classifying air flow is changed or regulated by changing the speed of the motor for the admirationstrom generating fan.
  • the classifying air flow can be changed separately via a motor-driven throttle.
  • the invention it is possible to produce a solid rib discharge or to adjust particle discharge from a tobacco fiber stream, wherein the adjustment and regulation takes place automatically. Due to the continuous measurement and control of the rib discharge, the tobacco stream is influenced in a targeted and automatic manner during the production of a tobacco rod or cigarette rod.
