Definitions

  • the invention relates to a method for producing (cigarette) packs with the method steps of the preamble of claim 1. Furthermore, the invention relates to a device for implementing the method according to the preamble of claim 9.
  • the subject of the invention is the treatment of packs in which the pack contents or an inner pack is encased by a blank made of packaging material which is problematic with regard to exact folding. In particular, it is about the production of correct folding edges in the area of folding tabs and the control of restoring forces in the area of the folding tabs after the folding step.
  • EP 1 016 593 B1 To create precise folding edges, the blank for an inner pack is provided with embossing lines for longitudinal and transverse folding edges.
  • the embossing lines are designed as groove-like deformations of the material. Due to the low dimensional stability of the material, this method cannot effectively eliminate the problems.
  • the object on which the invention is based is therefore to achieve exact folds for, in particular, thin-walled, critical (internal) blanks and, in particular, to avoid restoring forces in the region of side tabs.
  • the method according to the invention has the features of claim 1.
  • the technology of the invention therefore consists in pre-folding the folding edge to be produced by way of a pre-folding or auxiliary folding beyond the desired folding position (usually 90 °), in particular with the formation of a folding of (approximately) 180 °.
  • This pre-folding or auxiliary folding takes place in the area of a material supply formed by deformation of the blank, in particular in the area of a curved deformation of the inner blank adjacent to the folding edge to be produced, but at a distance from it.
  • the blank deformation can consist of a material curvature directed towards the free side, in particular in the form of a folding bead, which forms an approximately U-shaped fold in cross section.
  • This folding which goes beyond the standard folding (90 °), prepares an exact folding edge. Furthermore, the stresses that generate the restoring forces in the folding tabs are eliminated.
  • a folding web positioned in the plane of the folding flaps or parallel to these is preferably provided, which, due to the corresponding dimensions and / or arrangement, projects with a folding edge over the contour of the pack and thereby produces the folding bead as a pre-fold.
  • a counterfold is preferably assigned to the folding web, which causes the folding around the folding edge of the folding web, in particular a (stationary) folding switch which, during the transport of the inner pack, folds the initially flaps - side flaps - around the folding edge of the web so that the folding flaps start the outside of the folding web. Due to the (larger) dimension of the folding webs, the side tabs form a material protrusion protruding beyond the contour of the inner packing, namely the folding bead.
  • a folding of approximately 180 ° is created. Outside the area of the folding bars the folded bead is eliminated, in particular with the formation of a further (intermediate) folding curvature of the material until the longitudinal edges are finished and the side tabs are correctly positioned.
  • the folding steps i.e. the preforming or pre-folding of the blank in the area of the longitudinal edges, is preferably carried out during the transport of the cigarette group and (partially folded) blank with the aid of stationary folding and shaping elements which change in the manner of folding switches, i.e. with changing ones Dimension and / or contour along the path of movement, preferably on both sides of the package.
  • Double block cigarette packs are known, including the manufacture of the two inner packs in parallel cigarette lanes. In the area of a packing platform, the inner packs are pushed together in the transverse direction by a corresponding cross slide to the system and then inserted into a partially folded outer pack ( DE 28 10 586 C2 ).
  • block or cuboid packs in particular of inner packs 10 as the content of an outer pack 11, involves the precise formation of folded edges and / or the trouble-free positioning of folding tabs after folding along a folded edge.
  • the inner pack 10 contains a group of shaped cigarettes 12 to form a cigarette group 13, in the present case with a formation of two rows of cigarettes with the same alignment in pairs.
  • the cigarette group 13 is enveloped by an inner blank 14.
  • This is a tinfoil cut, a paper cut or a (multilayer) film cut, in principle in any case a thin-walled, unstable material.
  • the inner blank 14 envelops the cigarette group 13 in such a way that upright and transversely oriented packaging edges are formed as folded edges.
  • upright or longitudinal edges 15, 16 extending in the longitudinal direction of the cigarettes 12 are the subject of the innovation.
  • Four of these longitudinal edges 15, 16 are formed in pairs opposite one another at the corners or in the area of corner cigarettes of the cigarette group 13, so that a block-shaped inner pack 10 is formed in each case.
  • two inner packs 10 are arranged side by side as the content of the outer pack 11 to form a so-called double block pack.
  • the outer pack 11 as a hinged box consists of a (lower) box part 17, a cover 18 and a collar 19.
  • the latter is designed such that the (two) inner packs 10 lying next to one another are encompassed by the common collar 19.
  • a coupon 20 designed as a rectangular blank is arranged in the outer pack 11, specifically on the front side between a collar front wall 21 and the two inner packs 10.
  • the preferably rectangular inner blank 14 is placed around the cigarette group 13 such that a closed bottom wall 22, large front wall 23 and Rear wall 24 arise.
  • Narrow upright side walls 25, 26 and an upper or end wall 27 are formed from folded, partially overlapping folding tabs.
  • the side walls 25, 26 consist in particular of trapezoidal side flaps 28, 29 which are connected to the front wall 23 - outer side flaps 28 - on the one hand and to the rear wall 24 - inner side flaps 29 - on the other hand.
  • the side tabs 28, 29 are arranged due to appropriate folding along the longitudinal edges 15, 16 with mutual partial overlap in the region of the side walls 25, 26.
  • the end wall 27 also consists of (trapezoidal) end flaps 30, 31, likewise in connection with the front wall 23 (end flap 30) and with the rear wall 24 (end flap 31). Further folding tabs are formed on the upper and lower end regions of the side walls 25, 26, namely bottom corner tabs 32 and end corner tabs 33 connected to the bottom wall 22 on the one hand and the end wall 27 on the other hand and folded into the plane of the side walls 25, 26.
  • the procedure is such that (two) cigarette groups 13 are transported along a pack or fold path, hereinafter: cigarette path 34, at a distance from one another — continuously — and pass through work stations or fold stations.
  • cigarette path 34 a pack or fold path
  • inner blanks 14 are kept ready in a plane transverse to the transport direction and folded around the (free) cigarette ends lying forward in the transport direction with a U-shaped fold.
  • first folding station namely in a bottom folding station 36
  • the bottom corner flaps 32 are folded against the side areas of the cigarette group 13.
  • Another folding station follows, namely side folding station 37, in which the side flaps 28, 29 are successively folded, the inner (lower) side flap 29 first.
  • the front corner flaps 33 and then the front flaps 30, 31 are folded in a forehead folding station 38.
  • the cigarette block thus finished can be inserted as an inner pack 10 into a blank of an outer pack 11.
  • a special feature are folding measures in the production of folding edges or packing walls from folding tabs of the inner blank 14.
  • the production of the longitudinal edges 15, 16 of the inner packing 10 is particularly critical. On the one hand, it is a matter of correct formation of the folding edges there and, on the other hand, the dismantling from Restoring forces of the material in the area of folding tabs, in particular in the area of the side tabs 28, 29.
  • the folding, in particular of the longitudinal edges 15, 16 of the inner pack 10, is carried out in several successive folding steps, in particular during the transport.
  • material deformations are preferably carried out at the same time at a distance from the end position of the longitudinal edges 15, 16, in the present case by elevations in shape or with the formation of folded beads 39, 40.
  • These are offset in one plane from the front wall 23 or rear wall 24 of the Inner blank 14, with the inner pack lying flat, directed upwards and downwards, that is to say above the front wall 23 on the one hand and below the rear wall 24 on the other hand.
  • the folding beads 39, 40 of the inner blank 14 result from an essentially U-shaped deformation of the material in the region of the longitudinal edges 15, 16, so that a fold of approximately 180 ° is produced.
  • the side tabs 28, 29 are positioned approximately in the final folding position, that is to say directed transversely to the front wall 23 and rear wall 24 ( Fig. 2 ).
  • the folding beads 39, 40 are applied transversely to the plane of the front wall 23 and rear wall 24, in the formation shown ( Fig. 3 ) in the downward or upward direction.
  • the folding tabs namely the side tabs 28, 29, can be moved into the end position appropriate for the pack.
  • an intermediate deformation of the material during the deformation of the folding beads 39, 40 is advantageous, namely in such a way that folding arches directed sideways or transversely to the side walls 25, 26 arise ( Fig. 3 ).
  • These are finally deformed or eliminated by transverse loading and by deformation in the plane of the side walls, as a result of which the side tabs 28, 29 reach the final folding position without tension ( Fig. 4 ).
  • Another special feature of the method is that the steps described for pre-folding the inner blanks 14 are carried out along two parallel cigarette lanes 34, the (two) inner packs 10 assigned to an outer pack 11 passing through the individual stations 36, 37, 38 in parallel and simultaneously.
  • the mutually assigned inner packs 10 in the transverse direction brought together with the aid of cross-slides 43, preferably arranged on both sides, until the adjacent side walls 25, 26 abut against one another.
  • the transverse slides 43 have a double function in that they perform the final phase of the folding in the region of the inner side walls 25, 26 during the transverse thrust movement, namely the lifting of the folding arches 41, 42.
  • the folding arches 41, 42 in the region of the side walls 25, 26 facing each other of the two inner packs 10 are removed by pressing them together, so that the folds on both side walls 25, 26 are completed by the process of pushing the two inner packs 10 together.
  • the means to carry out the pre-folding ( 2, 3 ) are preferably fixed organs designed in the manner of folding switches in the region of the movement path of the cigarette groups 13 with an inner cut 14, that is to say in particular along the cigarette paths 34.
  • Each cigarette web 34 is assigned top guides 44 and underpasses 45, the latter serving as a support for the units of cigarette groups 13 and inner cut 14 transported in the longitudinal direction of the cigarettes 12.
  • Side guides 46 and 47 are arranged on the opposite side walls 25, 26 and are dimensioned in this way that the material deformations of the inner blank 14 can be carried out in the area of the longitudinal edges 15, 16, in particular the formation of the (sideways) folding arches 41, 42.
  • the (first) deformation of the inner blanks 14 is brought about by - upright - folding webs 48, 49 on either side of the inner packs 10 or the cigarette groups 13. These lie to form the upward and downward folding beads 39, 40 on the side regions of the cigarette groups 13.
  • the side flaps 28, 29 are folded around (upper and lower) folding edges 50, 51 of the folding webs 48, 49, so that the side flaps 28, 29 temporarily rest against the folding webs 48, 49, namely on their free (outer) side ( Fig. 2 ).
