Definitions

  • both the rotary blades 10 have through holes 23, but only the through holes 23 of a single rotary blade 10 have the function of connecting the inner end 20 of the chambers 18 with the pneumatic distributor 21, whereas the through holes 23 of the other rotary blade 10 have no function.
  • the pneumatic distributor 21 comprises a cylindrical body 24 which is still, namely does not rotate around the rotation axis 11, and is coupled to the rotary blades 10.
  • an upper rotary blade 10 is arranged in contact with the cylindrical body 24 and, by rotating around the rotation axis 11, it slides against the cylindrical body 24 that instead does not rotate around the rotation axis 11.
  • the cylindrical body 24 has a compartment 25 which is shaped like an arc of a circle, is coaxial with the rotation axis 11, can be permanently connected to a suction source, and is arranged in the area of the through holes 23 of the rotary blades 10 and therefore in the area of the inner ends 20 of the chambers 18 of the support disc 17.
  • the cylindrical body 24 has a compartment 26 which is shaped like an arc of a circle, is coaxial with the rotation axis 11, can be permanently connected to a source of compressed air, and is arranged next to the compartment 25 in the area of the through holes 23 of the rotary blades 10 and therefore in the area of the inner ends 20 of the chambers 18 of the support disc 17.
  • the cutting unit 8 comprises a cleaning device (namely a kind of scraper) which is arranged in a fixed position around the two rotary blades 10, arranged at a small distance from the two rotary blades 10, and has the function of cleaning the two rotary blades 10 from any extraneous elements (pieces of cardboard of the bottom wall 6) that have become wedged between the two rotary blades 10 or stuck to a rotary blade 10.
  • the cleaning device separates from the rotary blades 10 any extraneous elements (pieces of cardboard from the bottom wall 6) wedged between the two rotary blades 10 or stuck to a rotary blade 10.
  • a control station is also provided which could be arranged along the path P downstream of the cutting unit 8 and is provided with a viewing device which, by acquiring and analysing one or more images of the pack 1 of cigarettes, is able to establish whether the strap B produced by the double cut 7 has been correctly eliminated.
  • a viewing device which, by acquiring and analysing one or more images of the pack 1 of cigarettes, is able to establish whether the strap B produced by the double cut 7 has been correctly eliminated.
  • any packs 1 of cigarettes which do not conform to the desired specifications namely, in which the strap B produced by the double cut 7 has not been correctly eliminated
  • the cutting unit 8 described above allows to ensure the removal of the strap B after the double cut 7, avoiding that the strap B (or a piece of the strap B) can remain in contact with the bottom wall 6 of the pack 1 of cigarettes.
  • the cutting unit 8 described above is simple and inexpensive to implement since, compared to a similar known cutting unit, it requires modifications that are quick to make using commercial pieces or pieces that can be easily obtained with standard machining.
  • the cutting unit 8 described above allows the cut 7 of the bottom wall 6 to be made in a very precise and accurate way, always ensuring optimal functionality of the pack 1 of cigarettes.
