Definitions

  • the invention relates to a method for producing cigarette packs with the features of the preamble of claim 1.
  • the invention also relates to a device with the features of the preamble of claim 4 for a device for producing cigarette packs.
  • the inner collar is designed like a tray, namely with a collar front wall and transverse side or support walls and with a collar base.
  • the inner collar is arranged so that the front wall faces the front side of the inner package, namely an inner front wall.
  • the cigarette group is preferably not covered by the inner collar in the area of an end face and on the rear side.
  • the unit consisting of the group of cigarettes and the inner collar - hereinafter: block of cigarettes - forms the contents of the inner pack. This can be arranged in an outer pack, preferably in a hinged box.
  • the inner collar is then removed from the molding assembly by a ram and inserted into an adjacent pocket of a turret. This transports the folded inner collar to a loading station, in which groups of cigarettes fed by a cigarette revolver are pushed into the inner collar by a ram.
  • the object of the invention is to improve the production of units made up of cigarette group and inner collar—hereinafter cigarette block—and, in particular, to avoid misalignments in efficient packers.
  • a special feature of the process steps is that with the help of a folding turret, the inner collar is shaped in a single folding step, the cigarette group is fed in and the transfer to a block conveyor for transporting the cigarette blocks away, specifically for tray-like inner collars.
  • a further special feature are measures for folding folding flaps in the area of a collar base with the production of a glue-free connection of the folding flaps, exclusively by means of a plug connection.
  • inner pack 12 ( 15 ) consists of the cigarette group 11 and a covering made of sealing film, namely a film covering 13, which completely surrounds it an inner collar 14.
  • the inner collar 14 is manufactured in a first step and filled with a cigarette group 11 .
  • this is formed as a film tube 18, in the present example ( 14 ) with continuous tubular seam formed on the underside.
  • the cigarette blocks 16 are arranged within the film tube 18 at a distance from one another.
  • transverse sealing seams 20, 21 in the form of a fin seam are produced in the middle between successive cigarette blocks 16, with simultaneous severing of the film tube 18 between the successive cigarette blocks 16 in the region of the sealing seams 20, 21, so that inner packs 12 with lateral, protruding sealing seams 20, 21 in the area of side walls - inside walls - arise, in the execution as a fin seam.
  • the inner collar 14 can be designed in various ways, but has at least one large-area front wall or collar front wall 22 and transverse side tabs on both sides, so that the inner collar is U-shaped in cross section.
  • an end wall directed transversely to the walls 22, 23, 24 is also provided, namely a collar base 25.
  • the inner collar 14 is therefore designed in the shape of a tray.
  • Collar edges formed between the collar front wall 22 and side flaps 23, 24 are designed as bevel edges 26 with two parallel fold lines ( 7 ).
  • the cigarette blocks 16 designed in this way or in a similar way are transported into the wrapping station 15 by a block conveyor 27 .
  • the block conveyor 27 transports the cigarette blocks 16 at precise distances from one another, in this case by means of at least one driver 28 on the rear and preferably a stop 29 on the front.
  • the prepared film web 17 is lowered from above onto the block conveyor 27 or the successive cigarette blocks 16 in the region of the wrapping station 15 and placed on the front wall 22 of the collar. Laterally protruding areas are formed around the cigarette blocks 16 by stationary guiding and folding elements.
  • the block conveyor 27 ends in the area of the wrapping station 15 by being deflected downwards on a deflection roller 30 . In this area, the film web 17 is folded to such an extent that the film tube 18 is formed, which entrains the cigarette blocks 16 while maintaining the relative position.
  • the (in 14 not shown) hose seam produced, which stabilizes the wrapping of the cigarette blocks 16.
  • the film web 17 is fixed to the cigarette blocks 16, in particular to the collar front wall 22 pointing upwards.
  • the connection can be made by means of glue fields. In the present case, however, a connection is produced by thermal sealing.
  • the web of film 17 is subjected to heat and pressed against the collar front wall 22, creating an adequate bond.
  • an elongated sealing element is arranged above the film web 17 or the film tube 18, which transmits heat and pressure to the film web 17 over a sufficient transport distance. This involves a traveling belt 31 and a stationary sealing jaw 32 which bears against the free side of a traveling (lower) strand of the belt 31 .
  • the strand of the belt 31 runs friction-free with the film web 17 and transfers heat and pressure in the area of the collar front wall 22. It is important that the sealing unit 31, 32 extends into the area of the block conveyor 27 so that the fixing already takes place , While the packs or the cigarette blocks 16 are constrained by the block conveyor 27. Thereafter, the connection between the film web 17 and cigarette blocks 16 is sufficient to maintain the relative position.

  • the first manufacturing step deals with the inner collar 14.

  • the feed conveyor 38 consists of a continuous base for the blanks 14 - web plate 40 - on which the blanks 14 are transported at a distance from one another by upper belts 41, namely by being gripped by means of drivers until they are transferred to the folding turret 39.
