Definitions

  • the invention relates to a method for producing essentially cuboid packs, in particular cigarette packs in the form of a hinged box, from a blank with areas at least for the front wall, rear wall, side tabs for side walls and bottom wall. Furthermore, the invention relates to a device for performing the method.
  • a significant part of the cigarette packs on the international market is designed as a hinged box (also called hinge-lid packs).
  • the standard structure is such that a box part consists of the front wall, rear wall, side walls and bottom wall.
  • a hinged lid is hinged to the rear wall, which consists of the lid rear wall, lid top wall, lid front wall and lid side walls. The latter are formed from lid side tabs arranged on the lid rear wall and lid front wall.
  • the invention is concerned with the development of such packs, but also other packs.
  • the peculiarity consists in forming selected edges, known at right angles in the case of known packs, in particular longitudinal edges, beveled (polygonal) or rounded.
  • the dimensions of the bevel are expediently adapted to the diameter of the cigarettes.
  • the invention is therefore based on the object of proposing methods and apparatus for the production of packs with beveled (longitudinal) edges.
  • the method according to the invention is characterized in that, in order to form a pack with beveled (longitudinal) edges, the front wall with the bottom wall and the side tabs arranged on the rear wall at the same time with the rear beveled longitudinal edges in an upright position to the rear wall in that then the side flaps arranged on the front wall are folded into a position transversely to this, also to form the bevelled front longitudinal edges, and that the package is finally folded after filling the same.
  • the rear longitudinal edges, that is to say the rear wall, on the one hand and the front longitudinal edges on the other hand are accordingly folded into their position according to the invention in successive folding steps, with simultaneous formation of the bevel.
  • the blank is brought into an angular intermediate folding position in a pocket of a folding turret with simultaneous erection of the side tabs in the area of the rear wall and rear wall of the lid and with the formation of the bevelled longitudinal edges on the back due to the corresponding design of folding and shaping tools.
  • the blanking areas forming the cover extend in the extension of a horizontal blank leg.
  • the cover side tabs in the area of the cover front wall are likewise folded into their upright position during a separate working step, in particular simultaneously with the side tabs of the front wall, with the formation of beveled (longitudinal) edges.
  • the device according to the invention is derived from that according to DE-OS 2 440 006.
  • the stations for filling and finishing the packaging can be designed in the manner described in the aforementioned OS.
  • a plate-shaped folding turret which can be rotated about a vertical axis, is provided with pockets open at the top and on the radially outer side for receiving a blank in each case. These are fed along a blank conveyor path above a first folding station in a flat state and downward movement is introduced into the pocket of the folding turret by means of a stamp.
  • Pocket on the one hand and stamp or stamp plate on the other hand are designed, namely profiled, that the side flaps are erected by pressing the blank or the horizontal blank leg against the bottom of the pocket and at the same time the bevelled longitudinal edges are formed in this area.
  • the device is particularly suitable for producing hinged boxes with bevelled longitudinal edges, but also for other types of packs, e.g. B. cup packs, also with bevelled longitudinal edges.
  • the blank 20 shown in FIGS. 1 and 2 in an intermediate folding position is intended for a (cigarette) pack of the hinged box type.
  • areas are defined within the cut-out for forming front wall 21, bottom wall 22, rear wall 23.
  • Side flaps 24 are arranged on front wall 21 and further side flaps 25 are arranged on rear wall 23, which, when partially covered, form narrow side walls of the essentially cuboid packing.
  • Bottom corner flaps 26 are arranged at the lower ends of the side flaps 25 and folded over against the inside of the bottom wall 22 in the finished pack.
  • the blank parts described so far form a box part 27 of the package.
  • a hinged lid 29 connects to the rear wall 23 via a hinge 28.
  • This consists of the cut parts of the lid rear wall 30, lid top wall 31 and lid front wall 32.
  • Lid lid flaps 33 and 34 each connect laterally to lid rear wall 30 and lid front wall 32 to form the lid side walls to supplement or extend the side walls of the box part 27.
  • the lid side flaps are continued 33 each a lid corner flap 35 attached, which is folded against the inside of the lid top wall 31.
  • An inner tab 36 attached at the end of the cut, namely on the free side of the lid front wall 32, is folded over against the inside of the lid front wall 32 and serves to reinforce the same.
  • longitudinal edges 37 and 38 are designed in a special way.
  • Longitudinal edges 37 and 38 of the box part 27 and longitudinal lid edges 39 and 40 are designed as bevels or beveled edges. This gives the pack an octagonal cross-section.
  • Each of the longitudinal edges 37..40 consists of two individual edges 41 and 42, between which a cut strip 43 of limited width extends over a corner. The angles enclosed in the area of the individual edges 41, 42 are of the same size.
  • the width of the blanking strip 43 is adapted to the diameter of a cigarette, so that it can nestle against the blank in a space-saving manner in the region of the longitudinal edges 37.40.
  • Bottom wall 22 and top lid wall 31 are adapted to the above-described design of the pack, namely octagonal in each case in plan.
  • a horizontally directed cutting leg 44 is essentially formed by the rear wall 23 with the adjacent side tabs 25 and by the cutting parts for the hinged lid 29.
  • An upright cutting leg 45 consists of the bottom wall 22, the front wall 21 and the adjacent side tabs 24.
  • the bottom corner tabs 26 are brought into position during this first joint folding cycle (bearing against the inside of the bottom wall 22).
  • the side tabs 25 and the lid side tabs 33 are erected, with the formation of the bevelled longitudinal edges 38 and 39 in this cutting area.
  • the side tabs 24 are folded into a position transverse to the (erected) front wall 21, forming the bevelled longitudinal edges 37.
  • the lid side tabs 34 connected to the lid front wall 32 are erected while simultaneously forming the lid longitudinal edges 40.
  • the next folding step is to fold the inner tab 36, which has already been placed in an inclined position, against the inside of the lid front wall 32.
  • the previously erected cover side tabs 34 are moved back into an approximately horizontal original position.
  • the pre-folded blank is thus open at the top and on the radially outer side (area of the hinged lid 29), so that the contents of the pack (cigarette block) can be pushed into the blank in the radial direction.
  • the structure of the device for carrying out the folds described largely corresponds to that according to DE-OS 2 440 006. This applies in particular to the stations for filling and finishing the packaging.
  • An essential element of the device is a folding turret 46 with a plurality of pockets 47 arranged along the circumference, each for receiving a blank 20.
  • the folding turret 46 is designed as a flat plate and rotatable about an upright axis (in cycles).
  • a first folding station A In the area of a first folding station A, the flat blanks 20 are fed to the folding turret 46. To this end, the folding station A extends above the folding turret 46 in the region a in the conveying direction obliquely inclined bottom blank conveyor path 48. Between an upper L EADERSHIP 49 and a lower guide 50, the blank 20 fed by feed rolls 51 to a final position in exact relative location above a pocket 47 in the area of the folding station A. In the end position, the blank 20 with the front end (inner tab 36) comes into contact with a stop piece 52.
  • a side aligner 54 which can be moved back and forth in the transverse direction, is used for the lateral alignment of the blank 20 in this position and is driven laterally against the blank 20, so that it is in the Zuismeför erbahn d 48 on the opposite side aligning (see Fig. 7).
  • the bottom corner flaps 26 are preformed or pre-folded by angling or straightening them.
  • a corner flap folder 53 is mounted in parallel in the area of the blanking conveyor track 48, namely on parallel link core 55.
  • the C-shaped corner flap folder 53 is equipped with folding fingers 56, 57 which protrude from the sides into the area of the two bottom corner flaps 26.
  • the blank 20 is now inserted into the pocket 47 of the folding turret 46 by a downward movement, specifically by means of a form stamp 58 with a stamping plate 59 which can be moved up and down.
  • the form stamp 58 is attached to an angled or arcuate pressure lever 60 which is pivotably mounted and causes movement of the die 58 along the circular path 61.
  • the stamp plate 59 of the die 58 is dimensioned such that the rear wall 23, the rear cover wall 30, the upper cover wall 31 and the front cover wall 32 are gripped.
  • the pocket 47 is dimensioned such that the rear wall 23 and the lid rear wall 30 are pressed against a pocket bottom 62 by the stamp plates 59.
  • stamp plate 59 and pocket bottom 62 are matched to one another in their design.
  • the stamp plate 59 is polygonal in cross section, namely with external corners 63 and 64 for shaping the individual edges 41 and 42 in the region of the rear longitudinal edges 38 and 39 when the corresponding cut parts are pressed into the pocket 47
  • the pocket 47 which is bowl-shaped in cross section, is provided in the region of the transition from the pocket bottom 62 to the pocket side walls 65 with inner corners 66, 67 which lie opposite the outer corners 63 and 64.
  • Stamp plate 59 and pocket 47 are therefore in the relationship between the male and female.
  • the mutually facing shaped surfaces of the pocket side walls 65 on the one hand and of the stamp side surfaces 68 on the other hand are arranged obliquely, namely diverging upwards.
  • the blank 20 or the side tabs 25 or cover side tabs 33 are thereby brought into an intermediate folding position which diverges upwards (FIG. 7).
  • Pocket 47 and stamp plate 59 are formed with a cross-section that changes over their length.
  • the cross section of the pocket 47 and the stamp plate 59 corresponds approximately to the illustration according to FIG. 9, that is to say with the inside of the pocket side wall 65 upright and correspondingly upright outer surfaces of the stamp plate 59.
  • the lid side tabs 33 in the area of the lid rear wall 30 become vertical Folded position, that is, with a slight angular offset in relation to the side tabs 25 in the region of the rear wall 23.
  • the pocket 47 ends approximately in the region of the transition from the lid rear wall 30 to the lid top wall 31. The latter lies freely outside the pocket 47. There is also no lateral limitation for the lid corner flaps 35, since these are automatically erected with the lid side tabs 33.
  • the folding of the lid side tabs 34 arranged on the lid front wall 32 and the shaping of the longitudinal lid edges 40 extending here are carried out - outside the folding turret 46 or the pocket 47 - by means of separate folding tools arranged in a fixed manner in the area of the folding station A.
