Definitions

  • the invention relates to a method for producing in particular dimensionally stable packages of preferably thin cardboard, in particular folding cartons for cigarettes, with an outer envelope of sealable film, wherein folding flaps of the outer packaging surrounding the package by stapling .
  • Fastening be fixed in a folded position and then connected by thermal, in particular full-surface sealing in the region of overlaps.
  • the invention relates to an apparatus for producing such packages according to the preamble of claim 6.
  • the invention concerns measures for an improved production of such packages, in particular hinge-lid packs for cigarettes.
  • the invention has for its object to ensure an improved, especially wrinkle-free appearance of the outer sheath, by shrinking the film.
  • the invention is based on the finding that when the shrinking or heat treatment is initiated, the outer sheath is completely finished, ie all folding flaps have to be folded into the pack-type position and fixed in this position.
  • the outer sheath is completely fixed in the folding position suitable for packaging, without shrinkage treatment being initiated by this stitching or pre-seal. Thereafter, the package can be exposed directly to a shrinkage treatment or sealed in the usual manner in the field of folding flaps over a large area.
  • the device according to the invention as part of a packaging machine is designed such that a sealing station or sealing units for the folding flaps are arranged in front of stapling members which cause adhesion or sealing of the folded outer wrapping in the region of the folding flaps.
  • the drawings relate to a rectangular pack 10 of the type folding carton for cigarettes.
  • the pack 10 consists of a blank of thin cardboard.
  • the package consists of a box part 11 and a lid 12.
  • the package 10 is surrounded by an outer sheath 13 of thin film, namely a shrink film.
  • the outer sheath 13 forms according to the shape of the pack 10 large-area walls, namely front wall 14 and rear wall 15, narrow, elongated side walls 16 and 17 and end wall 18 and bottom wall 19th
  • the outer sheath 13 forms folding flaps, which are interconnected by thermal sealing.
  • side flaps 20 and 21 of the blank of the outer sheath 13 form a strip-shaped overlap 22. This overlaps the full length of the outer sheath 13 (FIGS. 3, 4).
  • the side tabs 20, 21 are connected together in the region of the overlap 22 by sealing, over the entire surface of the overlap 22, as shown in Fig. 1 by blackening of the sealing surfaces.
  • End wall 18 and bottom wall 19 also consist of folding flaps, namely from inside transverse tabs 23, 24 and outer, trapezoidal longitudinal tabs 25, 26.
  • the tabs 23..26 cover each other partially.
  • Fig. 2 is blackened or represented as a hatched area of the overlap area and thus the area of the lobes 23.26 interconnected by sealing.
  • the attachment of the large-area seals in the region of the overlap 22 and the bottom wall 19 causes at least the initiation of the shrinking process with respect to the outer sheath 13. This is especially disadvantageous if the sealing of the overlap 22 on the one hand and the seal of the end wall 18 and bottom wall 19 on the other hand successive steps are performed.
  • the folding tabs are connected to each other in preceding steps by stitching, the attachment of the stitch is associated with low or localized heat.
  • stitching is applied in the region of the overlap 22 of the side flaps 20, 21.
  • This consists in the embodiment of FIG. 3 of small-area point seals 27.
  • Several circular or oval point seals 27 are mounted along the (unfolded) overlap 22, with distances from each other.
  • At least one point seal 27 in each case is located in the area of the regions of the outer envelope that protrude beyond the pack 10 to form the transverse tabs 23.
  • FIG. 4 An alternative is shown in Fig. 4 by a sealing strip 28 extending over the full length of the blank or blank (unfolded) 22. This is of relatively small width, for example about 2 mm. As a result, a connection of the side tabs 20, 21 sufficient for the further folding process is provided, without the shrinkage process for the outer sheath 13 being introduced as a result of the heat supply.
  • the folding tabs 23..26 also small-area staples produced by thermal sealing are provided, namely two tacking strips 29, 30. This are mounted so that all folding tabs of the end wall 18 and bottom wall 19 detected, namely, are connected to each other locally. Namely, the stitching strips 29, 30 are located in a region in which respective transverse tabs 23 or 24 and both longitudinal tabs 25, 26 overlap one another.
  • the attachment of the stitching connections to the outer sheath 13 is expediently integrated into the production process of the outer sheath 13.
  • the device according to FIG. 6 is expediently part of a production line for cigarette packs.
  • the finished to the outer casing 13 packs 10 are fed to a horizontal packing web 31.
  • the packs 10 arriving at intervals from one another pass through a cutting unit 32.
  • the blanks are held ready by an upright cut conveyor 34 in an upright plane transverse to the package web 31, such that the blank of the outer wrapper 13 is folded in a U-shape around the package 10 conveyed along the package web 31.
  • the package 10 is transferred with the outer sheath 13 to a folding turret 35.
  • This is equipped with a plurality of pockets 36, each for receiving a pack 10 with outer sheath 13, in the present case, eight pockets 36, of which there are two each in a horizontally directed receiving position or Ausschub ein.
  • the pockets 36 are directed radially and open on the outside.
  • the transverse tabs 24 projecting there are folded on both sides of the pack, by means of fixed folding fingers 37 arranged in or on each pocket 36.
  • the packages 10 are conveyed into a first stitching station 38 and then into a second stitching station 39.
  • the first stitching station 38 corresponds to a vertical position of the relevant pocket 36.
  • the side flaps 20, 21 of the outer cover 13 are already folded upon reaching this first stitching station 38 into a position according to FIG. 3 or FIG. 4.
  • a heated stapling member 40 is moved to the radially outwardly directed side wall 16 of the pack 10. In this case, sealing tools 41 on the side tabs 20, 21 come to rest, in the region of the overlap 22.
  • the sealing tools 41 are formed according to the stapling to be produced, for example as individual projections for a point stitching of FIG. 3 or as a thin, continuous sealing jaw for Embodiment according to Fig. 4.
  • the stapling member 40 is pivotally mounted on a support arm 42.
  • the second stitching station 39 the stitching of the side flaps 20, 21 is completed by a correspondingly formed stitching member 43.
  • Two stapling members or two stapling stations 38, 39 are required in particular for short downtimes of the folding turret 35.
  • the pack of outer wrapper 13 designed in accordance with FIG. 3 or FIG. 4 is removed from the folding turret 35 in the radial direction in the region of an ejection station 44 and inserted into a folding web 45.
  • this horizontal folding web 45 the parts of the outer casing 13 projecting on both sides in the region of the end wall 18 and bottom wall 19 are folded, namely first during the extension of the transverse tabs 23 by a fixed folding finger 46 and then the two longitudinal tabs 25 and 26 by corresponding folding members 47 , so-called folding switches.
  • the package 10 with completely folded outer casing 13 arrives at a platform 48. From here, the packs 10 are cyclically raised to form a packing tower 49 up to the region of a correspondingly higher, horizontal sealing web 50.
  • stapling members 51, 52 are arranged on both sides of the folding web 45 and the platform 48, each with two stapling jaws 53 spaced apart according to the shape of the stapling strips 29, 30.
  • the stapling members 51, 52 are moved during the stoppage phase of the pack 10 against the end wall 18 and bottom wall 19.
  • the package 10 with now completely stapled outer sheath 13 is subjected to a seal in the usual way.
  • the side tabs 20, 21 are completely sealed by a sealing tool 54, which extends in height over several, namely three packs 10 and during three stoppage phases of the packs 10 in the region of the packing tower 49, the side tabs 20, 21 seal.
  • the packs 10 pass through the transverse web in the sealing web 50.
  • the packs 10 are positioned in two rows arranged one above the other.
  • the sideways end walls 18 and bottom walls 19 are completely sealed here by sealing jaws 55, and also during the respective stoppage phases of the packs 10 in several Siegeltakten.
