Definitions

  • the invention relates to a film wrapping machine for cuboid objects, in particular cigarette packs, with a revolver which has cells and can be rotated step by step, a slide for pushing the objects into a cell, a feed device for film sections into the area between the slide and cell, and with an upper and a Unterfalter, wherein the Oberfalter is formed by a revolver arc beginning in the direction of rotation of the revolver adjacent to the position of the cell in the receiving position and the lower folder is movable from below into contact with the outward-facing side of the object received in the receiving position cell by means of a drive .
  • the object of the invention is therefore to provide a film wrapping machine of the type mentioned at the outset, which ensures gentle handling of the edges of the packets of cigarettes with a simple construction.
  • the drive for the sub-folder is designed such that the sub-folder passes through a closed circulation path on which the sub-folder of the cell in the receiving position is from a position at a distance from the cell and outside its insertion area to the system on the Object inserted into the cell overlaps the lower flap of the film section, moves along the region of the lower flap until it is essentially completely covered, moves further in the direction of the cell rotation at the beginning of the indexing of the revolver and then vented and into the Starting position returns.
  • a curve-controlled parallelogram drive is particularly suitable as the drive, but a drive from a guide rod guided in a guide can also be used, the guide itself being additionally pivotable.
  • the film wrapping machine shown comprises a revolver 1 which has cells 2 for receiving cigarette packs 3 and can be rotated step by step in the direction of the arrow by a cell division in each case by means of a stepping drive drive (not shown). Furthermore, a slide 4 is provided, by means of which a cigarette packet 3 brought into the insertion position can be pushed along a transfer path 5 into the cell 2 of the revolver 1 which is in the receiving position.
  • a feed device 6 for film sections 7, which are usually provided with a tear strip is provided.
  • the feed device 6 comprises a rotating and a fixed knife 8, 9 and a pair of feed rollers 10 which conveys the film section 7, separated by the knives 8, 9 from a film band 11, for wrapping a cigarette packet 3 into the transfer path 5 of the cigarette packet 3, which transports the film section 7 entrains when pushed into cell 2 by slide 4.
  • the film section 7 first comes into contact with the leading side of the cigarette packet 3 and then into contact with the upper and lower sides, so that in the case of the cigarette packet 3 located in the cell 3, the lower and upper rollover 12, 13 to the outside opposite the cell 2 survive.
  • the film section 7 protrudes laterally, cf. FIG. 2, the end tips 14 having already been folded in by corresponding side folders 15 when pushed over.
  • a folder 18 is also provided, which is connected to a parallelogram drive 20 via a support element 19.
  • the parallelogram drive 20 comprises two bearing sleeves 22, 23 fastened at a distance from one another in a housing wall 21, each of which serves for mounting one of two parallel axes 24, 25.
  • a crank 26 Located on axis 24 a crank 26.
  • the crank 26 receives an axle 27, on which a rod 28 is also supported at one end, while the other end is rotatably arranged on an axle 29 of a crank 30.
  • the crank 30 is rotatably arranged with respect to the axis 25.
  • the axis 25 is connected to a lever 31 which carries at its free end two rollers 32 for engagement with two control cams 33.
  • the movement sequence of the lower folder 18 is controlled via the latter.
  • the rod 28 can be designed to be telescopically compressible against a spring 34.
  • FIG 3a shows the starting position of the lower folder 18 after a cigarette packet 3 with a film section 7 has been inserted into the cell 3 of the revolver 1 in the receiving position. From this position at a distance in front of the cell 3 and outside the transfer path 5, the lower folder 18 first approaches the lower flap 12, in order then to move obliquely towards the side of the cigarette packet 3 which slightly protrudes from the cell 3, taking the lower flap with it 12 to approach the packet of cigarettes 3 and to come into contact with it with partial overlap with the lower rollover 12.
  • the underfold 18 moves along the cigarette packet 3 until it substantially completely covers the lower rollover 12 which has been brought into contact with it, FIG. 3b.
  • the lower folder 18 exerts a pulling action due to friction on the lower rollover 12 in the direction away from the fold-over edge of the lower rollover 12 in order to tighten the lower rollover 12.
  • the revolver 1 begins to rotate and the subfold 18 moves a short distance in the direction of the cell path with the cigarette packet 3.
  • the upper flap 13, which is located adjacent to the edge of the revolver arch 16, is first folded obliquely in the direction of the lower flap 12 already flipped by the bevel 17 during the movement of the revolver 1.
  • the upper flap 13 slides along the bevel 17 and initially forms an angle to the packet of cigarettes 3 such that the lower folder 18 can escape, which at the beginning of the folding of the upper flap 13 through the section of the upper folder 16 or vented somewhat beforehand and thus releases the edge around which the lower rollover 12 has been folded over, so that it is not claimed, FIG. 3c.
  • the retractor 18 has no retracting effect on the folded-over lower flap 12.
  • the lower folder 18 returns to its starting position according to FIG. 3a, during which the next packet of cigarettes 3 is inserted into a new cell 3 in the receiving position together with a film section 7.
