  • the storage bays are at a predeterminable loading frequency of the storage bays 40, 40 'and a corresponding predetermined charging time, which can be predetermined for example directly via a machine control device 23 40, 40 'filled as evenly as possible. This may be due to the respective geometry of the devices, in particular the device according to Fig. 1
  • one of the storage bays 40, 40 ' is filled with more tobacco than the other.
  • the invention proposes to adapt the throughput of tobacco from the storage compartments 40, 40 'as a function of the damming height 27, 27' by varying the rotational speed of the withdrawal rollers 42, 42 '.

  • the controller 22 is connected to the engine control device 23 via a cable 24. Signals may be sent from the controller 22 to the engine control device 23 as well as the reverse path.
  • the controller 22 receives the detected signals of the sensors 11-16 and converts them into a control signal, by means of which the speed of the removal rollers 42, 42 ', which are connected to the controller via cables 25 and 26, are controlled. This results in a regulation of the filling level or accumulation height 27, 27 'of the tobacco 28, 28' in the storage spaces 40, 40 '.
  • the controller can be, for example, a conventional PID controller whose parameters can be set by the skilled person by simple trial and error.

The sensors may also be designed to indicate a relatively precise position of the accumulation height 27, 27 'in the respective storage spaces 40, 40'. So it can position sensitive sensors such as a CCD array be predetermined. The accuracy can be in the range of a few millimeters. Depending on the type of sensors, the control parameters must then be set.
  • the distribution element 39 is also correspondingly variable to control and not set with fixed predetermined values. It is recommended in this case, in particular the charging time of the respective storage shaft 40, 40 'of the damming height 27, 27' adapt. The lower the damming height 27, 27 ', the higher the feeding time should be.
  • the loading duration of the respective storage compartments is fixedly determined for different lengths of time. This can be predetermined by fixed presettings, for example in the machine control device 23. The loading periods could then possibly be varied manually, if over a longer period of time, a change in the damming height 27, 27 'results, which is undesirable. However, it still makes sense to regulate at least one fine adjustment of the damming height 27, 27 'via the flow of tobacco from the stowage.
  • the mean value of the accumulation height 27, 27 'and / or the sum of the delivery rates or the tobacco flow of the removal rollers 42, 42' serves to control the delivery rate of the steep conveyor 17.
