Definitions

  • the present invention relates to a method and unit for simultaneously forming multiple tobacco mats on a multiple-rod cigarette manufacturing machine.
  • the partition member normally divides the input stream of shredded tobacco into substreams equal in number to the upflow conduits to form an equal number of tobacco mats, which should theoretically be identical.
  • identical mats which presuppose a homogenous input stream of shredded tobacco across its whole section, are difficult to achieve, and cigarettes formed by cutting rods produced from different tobacco mats invariably differ slightly.
  • EP-1364588-A1 was filed before, but published after the date of filing of the present application and discloses an arrangement for the formation of at least two tobacco rods in a cigarette rod making machine.
  • an input stream of shredded tobacco is fed to a switch conduit selectively alignable with the inputs of two downflow conduits, each of which communicates via a respective carding assembly with a respective upflow conduit closed by a respective conveyor belt for a respective tobacco mat; the switch conduit being switched between positions selectively aligned with the downflow conduits in response to a clock signal of predetermined frequency.
  • a unit for forming mats of shredded tobacco on a multiple-rod cigarette manufacturing machine as claimed in claim 4 and, preferably, in any one of the following Claims depending directly or indirectly on claim 4.
  • Number 1 in the accompanying drawing indicates as a whole a dual-rod cigarette manufacturing machine, which comprises an input portion defined by a unit 2 for forming two mats 3 of shredded tobacco on the underside surface of respective parallel conveyor belts 4 made of material permeable to air, and which run directly beneath respective suction boxes 5 for retaining mats 3 on respective conveyor belts 4 by suction.
  • Unit 2 comprises a loading hopper 6 for an input stream 7 of shredded tobacco fed to the top of hopper 6 by a known tank conveyor 8 .
  • Beneath hopper 6 unit 2 comprises two side by side, substantially parallel downflow conduits 9 in a plane parallel to the drawing plane.
  • Each downflow conduit 9 is closed at the bottom by a respective carding assembly 10 comprising a carding roller 11 rotating about an axis 12 in a direction 13 , and a known thrower roller 14 substantially tangent to respective carding roller 11 and rotating about an axis 15 parallel to axis 12 in an opposite direction 16 to direction 13 .
  • each downflow conduit 9 communicates, via relative carding assembly 10 , with the bottom end of a relative upflow conduit 17 closed at the top output end by relative conveyor belt 4 .
  • a respective intermediate partition 18 defines, to the side of the input end of relative upflow conduit 17 , a respective conduit 19 , which flows at the top into relative upflow conduit 17 at a given distance from relative conveyor belt 4 , and communicates at the bottom with a respective outlet of a compressed air supply circuit 20 .
  • switch conduit 22 alignable selectively with the inputs of the two downflow conduits 9 .
  • switch conduit 22 extends between two fixed walls 23 (only one shown) parallel to the plane of the accompanying drawing; and switch device 21 comprises two valve members 24 laterally defining switch conduit 22 and forming the cranks of an articulated parallelogram 25 , which also comprises a connecting rod 26 connecting the two valve members 24 .
  • Each valve member 24 in section, is substantially in the form of an isosceles triangle, and is hinged at a top vertex to fixed walls 23 , which define the frame of articulated parallelogram 25 , to oscillate about a respective axis 27 parallel to axes 12 and 15 .
  • Valve members 24 are defined laterally by respective flat facing surfaces 28 , which are maintained parallel by connecting rod 26 and define, between them and together with fixed walls 23 , switch conduit 22 .
  • each valve member 24 is defined by a cylindrical surface portion 29 , which, as switch device 21 oscillates, closes a respective downflow conduit 9 when switch conduit 22 is aligned with the other downflow conduit 9 .
  • Switch device 21 is powered by a motor 30 , which is connected to one of the two axes 27 to oscillate articulated parallelogram 25 between two positions aligning switch conduit 22 with one or the other of the two downflow conduits 9 , and is controlled by a logic unit 31 , which activates motor 30 to switch conduit 22 between said two positions following the emission of a “minimum level” signal and “maximum level” signal emitted by a level detecting device 32 comprising a number of sensors 33 along each downflow conduit 9 .
  • the switch is made when the level of shredded tobacco in the downflow conduit 9 not being supplied at the time reaches the “minimum level”; or after a given supply time of one of downflow conduits 9 , providing the other downflow conduit 9 in the meantime does not reach the “minimum level”; or when the downflow conduit 9 being supplied reaches the “maximum level”.
