  • BRIEF DESCRIPTION OF THE DRAWINGS
  • Preferred exemplary embodiments of the invention will be described in the following on the basis of the drawings, in which:
  • FIG. 1 shows a first variant of a device for applying flavorings, in a schematic illustration,
  • FIG. 2 shows a second variant of a device for applying flavorings, in a schematic illustration,
  • FIG. 3 shows a third variant of a device for applying flavorings, in a schematic illustration, and
  • FIG. 4 shows a fourth variant of a device for applying flavorings, in a schematic illustration.
  • DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
  • A first variant of a device for applying flavorings is shown in the schematic illustration according to FIG. 1.
  • Flavorings here are kept available in two containers 10. A conduit 11 leads from each of the containers 10 to a valve 12. A further conduit 13 leads from the valve 12 to an applicator unit 14. The applicator unit 14 serves for the application of flavoring 15 to a medium 16.
  • For the uniform distribution of flavoring 15 on the medium 16, a distributor element 17 is provided adjacent to the applicator unit 14.
  • The elements of the device which have been described so far are heatable. A heating-regulating unit 18, which is connected to the mentioned elements via conduits 19, serves for controlling and/or regulating the heating.
  • Weighing units 20, in particular in the form of weighing cells, are assigned to each of the two containers 10. With said weighing units 20, the filling level of the containers 10 is measured. In order to indicate the filling levels of the containers 10, a filling-level indication means 21 is connected to the weighing units 20 via conduits 22.
  • The containers 10 are pressurized at a low pressure of <0.5 bar. Pressure control takes place by way of a switchover valve 23 and a proportional valve 24.
  • A machine controller 25, which, via conduits 26, is connected to the applicator unit 14, the heating-regulating unit 18, the valve 12, the valve 23, the proportional valve 24 and the filling-level indication means 21, is provided for controlling the device.
  • The device described so far substantially functions as follows: flavoring 15 is conveyed out of the containers 10 by means of positive pressure, wherein, by means of the valve 12, it is controlled from which of the two containers 10 flavoring 15 passes to the applicator unit 14.
  • The applicator unit 14 contains a controllable valve for the application of flavoring 15 to the medium 16. In the shown exemplary embodiment, the medium 16 is a blank for an inner liner of a cigarette pack.
  • During the application of flavoring 15, the medium 16 is moved past the applicator unit 14, the valve being located at a short distance from the medium 16. Applied flavoring 15 is uniformly distributed by way of the distributor element 17, which may be configured as a smoothing strip, for example. Alternatively, the valve of the applicator unit 14 may also substantially bear on the medium 16.
  • The pressure in the containers 10 is regulated via the proportional valve 24 and the switchover valve 23. The proportional valve 24 serves for regulating the pressure. By means of the switchover valve 23, the pressure is directed to that container 10 which is in operation.
  • As soon as a low filling level is detected in preferably one of the containers 10 by means of the weighing units 20, said container 10 is accordingly swapped for a filled container 10, or the container 10 is filled in situ. Preferably, conveying is in each case performed only from one container 10 at a time. However, it is also conceivable for flavoring 15 to be conveyed simultaneously from both containers 10.
  • The flavoring 15, in the present case, is menthol which is preferably processed in liquid form. The use of other flavoring or aromatic substances in other states of matter is, however, also conceivable.
  • FIG. 2 shows a second variant of the device. From a non-pressurized container 10 for receiving flavoring 15, flavoring 15 is conveyed via a heatable conduit 11, by means of a pump unit 27 which is arranged in the conduit 11, to the applicator unit 14 and, as described above, applied to the medium 16. The pump unit 27 may be a gear pump, for example.
  • Again, a heating-regulating unit 18 is connected to the elements of the device via conduits 19. A machine controller 25 controls, or regulates, the applicator unit 14, the heating unit 18 and the pump unit 27 via conduits 26.
  • Flavoring 15 is filled into the container 10 via a filling funnel 28, is liquefied owing to the heating of the container 10, and, by means of the pump unit 27, is pumped from the container 10 to the applicator unit 14 and applied to the medium 16.
  • A further variant of the device is shown in FIG. 3. From a non-pressurized container 10, flavoring 15 is supplied, via a conveying unit 29, to a container 10, which is arranged at a higher level and is heatable. Flavoring 15 is supplied from the container 10 via a conduit 11 to the applicator unit 14.
  • As is the case in the preceding exemplary embodiments, a heating-regulating unit 18 having corresponding conduits 19 and a machine controller 25 having corresponding conduits 26 are provided.
  • In the present case, the conveying unit 29 is configured as a bucket conveyor which, proceeding from the lower container 10, is arranged in an encapsulated or enclosed casing 30.
  • When processing menthol as flavoring 15, menthol crystals are transported by means of the elevator conveyor into the container 10 which is at a higher level and heatable. The container 10, for example, may be situated 3 or 4 m above the machine or the applicator unit 14, in order to build up the corresponding pressure for transporting the menthol that has been molten or liquefied therein.
  • A fourth variant for applying flavorings is shown in the schematic illustration according to FIG. 4.
  • Flavorings here are kept available in two containers 10, 31. From a first container 31, which serves as a storage container, a conduit 11 leads, via a valve 23, to a second container 10, which serves as a processing container. A conduit 13 leads from the second container 10 to the applicator unit 14.
  • The elements of the device which have been described so far are heatable. A heating-regulating unit 18, which is connected to the mentioned elements via conduits 19, serves for controlling and/or regulating the heating.
  • Weighing units 20, in particular in the form of weighing cells, are assigned to each of the two containers 10. With said weighing units 20, the filling level of the containers 10 is measured. In order to indicate the filling levels of the containers 10, a filling-level indication means 21 is connected to the weighing units 20 via conduits 22.
  • Both containers 10, 31 are pressurized by positive pressure. The (storage) container 31, which is on the left in FIG. 4, when required, feeds liquid flavoring 15, or menthol, to the (processing) container 10, which is on the right in FIG. 4.
