Definitions

  • the invention relates to a tobacco distributor for cigarette rod machines, with a feed means for loading a tobacco to a fleece-spreading pin roller.
  • Modules of the type described at the outset largely determine the overall height of the machines mentioned, since certain requirements must be met with regard to the indispensable quality criteria of the end products produced in order to loosen, distribute or spread and compress the tobacco in the preparation phase.
  • the invention has for its object to significantly reduce the overall height of the tobacco distributor while ensuring proper operation.
  • the feed means is designed as a substantially horizontally aligned storage well equipped with a vibratory conveyor drive.
  • a slight inclination of the stowage shaft both inclines in the direction of conveyance and increases in the direction of conveyance also ensures proper operation.
  • a perfect function is guaranteed both with a swinging top wall and with a fixed top wall.
  • a supportive effect with regard to a uniform distribution and filling of the pin roller is achieved according to a further development in that the stowage shaft in its mouth area is assigned a screed strip that oscillates parallel to the axis of the pin roller on the roller outlet side.
  • a special seal between the pin roller and the stowage shaft can be dispensed with, whereby according to a further development for better derivation of the tobacco passing through the gap, an inclined ramp adjoining a bottom plate of the stowage shaft in the region of the mouth, a drop chute extending below the pin roller limited.
  • the storage chute is provided at the rear end in its task area with a ramp that adjoins its base plate and is inclined downward against its conveying direction.
  • the tobacco is transported upwards by the vibrating conveyor drive along the ascending ramp, but the heavier foreign components are separated out in the opposite direction.
  • a sensor monitoring the filling height is embedded in a top wall of the storage shaft. If the filling is inadequate, this can correspondingly control the delivery rate of tobacco supply means arranged upstream.
  • the storage chute is provided with a chute section which extends essentially vertically downwards and ends at the upper periphery of the pin roller Mistake.
  • the function of the stowage shaft is optimized in such a way that the tobacco is redirected into the vertical shaft section, so that any gaps on the horizontal conveying section are closed with certainty. It has also been shown that with this design, a separate scraper bar or a corresponding scraper roller at the outlet of the vertical shaft section can be dispensed with, since the reciprocating movement of the outlet of the vertical shaft section above the pins of the customer pin roller satisfactorily results in this can be filled.
  • an additional improvement in the filling of the pin roller is achieved in that the conveying cross section of the storage shaft increases continuously in the conveying direction to the end of the horizontal shaft section and from there to the end of the vertical shaft section.
  • This increase in cross-section is expediently achieved in that the top wall is at a distance from the counter wall that increases in the conveying direction towards the end of the stowage shaft.
  • the vibratory conveyor drive of the storage shaft naturally works with a high vibration frequency.
  • the vibratory conveyor drive be provided with an eccentric rod designed as a leaf spring. This arrangement eliminates the need for connecting rod bearings and the like that are susceptible to wear.
  • the advantage achieved by the invention is that surprisingly, with the construction height of the storage shaft reduced by at least part of the length of the storage shaft, a continuous, complete filling of the pin roller, which at all times covers the machine output, is ensured. In this way, a closed tobacco fleece is always formed, with which the subsequent strand build-up can be made without disturbances and quality losses.
  • the distributor has a pneumatic feed lock 1 for tobacco, the lock chamber 2 of which is separated from an air extraction line 4 by a sieve bottom 3 and is connected to a storage container 7 via a pivotable, controllable flap 6.
  • the chamber 11 is also separated from an air extraction line 13 by a screen plate 12.
  • a metering roller 16 which can be driven to rotate in the direction of arrow 14 and is designed as a rake roller, and a combing roller 17 which is driven in opposite directions and at three times the circumferential speed.
  • rollers 18 and 19 Below these rollers are inclined guide plates 18 and 19, and below the guide plate 18 there is a vertical magnetic strip 21.
  • the elements mentioned are on the feed side of a horizontally oriented stowage shaft 22, which has an eccentric 26 which can be driven by a leaf spring bearing 23 and a motor 24 existing vibratory conveyor drive is equipped.
  • the storage shaft 22 is provided with a ramp 27 which is inclined towards the rear or counter to its conveying direction and which ends at the end in a collecting channel 28 of the storage shaft 22.
  • a combing roller 29 and a sensor 32 embedded in a top wall 31 are assigned to the top of the storage shaft 22.
  • the storage shaft 22 In its outlet or mouth area, the storage shaft 22 is assigned a pick-up pin roller 34 which rotates in the direction of the arrow 33 and a scraper bar 36 which oscillates parallel to the axis of the pin roller 34 on the roller outlet side.
  • the pin roller 34 works with a considerably faster rotating drum roller 37, under which one Chute 38 extends.
  • an inclined downward ramp 39 extends into the chute 38.
  • a transverse duct 41 branches off from the chute 38, into which blowing nozzles 42, 43 are directed and which merges into a curved guide surface 44, into which blowing nozzles 46 likewise open.
  • a suction line conveyor 47 connects to the guide surface 44.
  • the space extending above the guide surface 44 is connected to an air extraction line 49 via a screen plate 48.
  • the drop chute 38 which continues downward after the transverse channel 41, is connected via a cellular wheel sluice 51 to a riser 52 which opens into a collecting conveyor 53 at the bottom and into the transverse channel 41 or into the guide surface 44 at the top and also on one side wall thereof Blow out nozzles 54.
  • the mode of action is as follows: By swinging the flap 6 into the dash-dotted position, cut tobacco is discharged into the storage container 7 in portions. Any excess tobacco that is returned is fed via the transport means 11 to the combing roller 17, which at the same time deflects the cut tobacco discharged from the storage container 7 by the metering roller 16. Metal parts 56 are retained by the magnetic strip from the tobacco falling past the magnetic strip 21 in this way, while the tobacco falls onto the inclined ramp 27 of the storage shaft 22.
  • tobacco and heavier foreign bodies 57 are separated, for example stones, in that the tobacco is conveyed upwards on the ramp 27 by the oscillating drive of the storage shaft 22, while the foreign bodies 57 slide downwards into the collecting channel 28 of the storage shaft 22, from which they run out of time can be removed at time.
  • the supply or replenishment of the tobacco in the storage shaft 22 is set so that the tobacco accumulates in the horizontal conveying section of the storage shaft 22 up to its top wall 31, the combing roller 29 paddling the excess back in the entrance area to the horizontal conveying section.
  • the storage volume formed in this way is maintained in the long term when the tobacco is continuously discharged by means of the pin roller 34 and the scraper bar 36, by the sensor 32 always increasing the conveying capacity of the upstream conveying means accordingly if the filling is found to be inadequate or incomplete.
  • the tobacco shower knocked out of the pin roller 34 by the beater roller 37 into the chute 38 and combined with the tobacco sliding down on the inclined ramp 39 is detected by the blow nozzles 42 and 43 at the level of the transverse channel 41, with lighter components being conveyed directly onto the guide surface 44 and heavier components (eg ribs) fall further down and are discharged through the rotary valve 51.
  • the riser 52 there is again a separation of heavier rib parts which fall no further processed and fall into the collecting conveyor 53 and lighter rib parts which are again combined with the main tobacco flow along the guide surface 44 by the blowing nozzles 54.
  • the tobacco fleece, which strives upward along the guide surface 44 and is supported by the blowing nozzles 46, is then transferred to the suction strand conveyor 47 to form a tobacco strand.
  • the storage well 122 a horizontal shaft section and a shaft section 159, which extends vertically downward and ends at the upper periphery of the pin roller 134, which form a sharp-edged deflection zone 161, at which the tobacco is redeployed, with the gaps in the horizontally advanced tobacco mass as it descends in the vertical shaft section getting closed.
  • the top wall 131 of the storage shaft 122 also swings, whereby it has a distance from the counter wall, that is to the horizontal floor or to the vertical rear wall of the vibrating conveyor, increasing in the conveying direction towards the end of the storage shaft.
