Definitions

  • Apparatus for delivering cigarettes from a [54] APPARATUS FOR MANIPULATING ROD-SHAPED cigarette machine to a packing machine comprises a supply conveyor which advances a succession of cigarettes past three transfer conveyors each of which removes from the succession a series of groups in such a way that the first transfer conveyor permits predetermined numbers of cigarettes which can form two groups to advance to the second transfer conveyor and that the second transfer conveyor removes a group from each predetermined number and allows a group of cigarettes to reach the third transfer conveyor.
  • All of the transfer conveyors supply groups to the pockets of an assembly conveyor which forms blocks of 20 cigarettes each and delivers such blocks to hollow mandrels in the conveyor of the packing machine.
  • the supply conveyor receives cigarettes from a feed which in turn receives cigarettes directly from a cigarette machine.
  • the present invention relates to apparatus for manipulating rod-shaped articles.

These pressure channels are connected to the atmosphere or to a compressor or another source of compressed air or other gas.
  • the flutes 307 are grouped into a series of groups or sets 381, 382, 383. When the flutes 307 of the set 381 contain cigarettes F, they are connected with the suction channel 368 by holding means in the form of suction ducts 384 and 386.
  • the flutes 307 of a set 383 are connected with the suction channel 371 by way of holding means or suction ducts 389, 391 when they deliver cigarettes F toward the transfer station P, and these flutes are connected to the pressure channel 374 by the corresponding ducts 389, 391 when they arrive at the transfer station P.
  • FIG. 9 illustrates a fourth apparatus which is very similar to the apparatus of FIG. 6 with the sole exception that the pockets or receiving means (including those shown at 417, 418, 419, 420 and 421) of the endless assembly chain conveyor 406 are closer to each other than the pockets 217, 218, 219, 221 of the chain conveyor 206. This is due to the fact that the conveyor 406 is operated intermittently. Suction in the flutes 407 of the belt 401a in the supply conveyor 401 can be produced in a manner as shown in FIG. 6 or as shown in FIGS. 7-8. The remaining parts of the apparatus shown in FIG. 9 are denoted by numerals corresponding to those employed in FIG. 6 plus 200.
  • the difference between the pitch T of the pockets 417-421 on the assembly conveyor 406 and 20! is proportional to the duration of intervals during which the assembly conveyor dwells between successive advances in a direction to the left, as viewed in FIG. 9. Otherwise, the operation of this apparatus is practically identical with that of the apparatus shown in FIG. 6.
  • FIG. 10 there is shown an apparatus whose supply conveyor 501 (including an endless belt or band 501a with flutes 507 and suction chambers 564-566) and transfer conveyors 502-504 (with withdrawing means 511, 508, 513) are identical with the corresponding conveyors of the apparatus shown in FIG. 6.

  • Each of these receiving means comprises a pocket with three upright compartments or shafts defined by outer walls 527 and thin intermediate walls or par titions 575.
  • each median compartment is located at a level above the bottoms of the adjoining outer compartments so that the cigarettes F of the median group or layer C in an array or block E are automatically staggered with reference to the cigarettes of the outer layers or groups B and D.
  • Each transfer conveyor comprises two coaxial and axially spaced disks or wheels (see the disks 502d, 502:2 of the con veyor 502) and such disks carry the halves of the respective withdrawing means.
  • the walls 575, 527 of each pocket are disposed between the disks of the transfer conveyors so that they automatically remove the cigarettes F of the respective groups B, C, D while the pockets travel below the transfer conveyors.
  • the assembly conveyor 506 is at a standstill during delivery of cigarettes F into its pockets. Complete arrays E are expelled from filled pockets while the conveyor 5% is at a standstill.
  • the improved apparatus can be modified in a number of ways without departing from the spirit of the present invention.
  • the number of transfer conveyors can be reduced below or increased above three.
  • the apparatus can be designed to assemble blocks each of which comprises two, four or more layers or groups and wherein the cigarettes of one or more layers may but need not be staggered with reference to the cigarettes of the other layer or layers.
