Definitions

  • the invention relates to a method of producing packs having an outer wrapper made of shrink-wrapping film, namely, a method of producing (cuboidal) packs having an outer wrapper made of sealable shrink-wrapping film, in particular a cigarette pack of the hinge-lid-box type, wherein folding flaps of the outer wrapper are connected to one another by thermal tacking and (subsequent) sealing and the outer wrapper is subjected to shrink-wrapping treatment by in particular surface-area heat-discharging mechanisms in the region of mutually opposite surfaces or walls of the pack or outer wrapper—in the case of a hinge-lid box (for cigarettes) a front wall and rear wall, on the one hand, and (upright) side walls, on the other hand—characterized in that surfaces of the packs or walls of the outer wrapper are subjected individually or in pairs, simultaneously or one after the other, to heat and pressure for sealing purposes and/or shrink-wrapping treatment, wherein some walls of the outer wrapper are subjected to a sealing treatment using heat and pressure and
  • Packs made of in particular thin cardboard and an outer wrapper made of film are subjected, providing the film has appropriate technical suitability for such a purpose, to a shrink-wrapping treatment in order that the pack is enclosed in a smooth and crease-free manner, under tensioning, by the film.
  • the focus here is on (cigarette) packs of the hinge-lid-box type having such an outer wrapper.
  • the packs are guided through a shrink-wrapping station, in the region of which the upwardly and downwardly directed large-surface-area pack sides—front wall and rear wall of the outer wrapper—are subjected, by plate-like heat-discharging mechanisms, to heat measured out for the shrink-wrapping process (EP 1 103 465 A1).
  • the invention concerns the further development of such production process, in particular in terms of ensuring that the folding flaps are sealed in a manner which is satisfactory from a technical and quality point of view and, furthermore, the provision is made for an optimum shrink-wrapping treatment, to be precise with increased output capacity of the (packaging) machine and shorter cycle times brought about as a result.
  • the method according to the invention is characterized by a method of producing (cuboidal) packs having an outer wrapper made of sealable shrink-wrapping film, in particular a cigarette pack of the hinge-lid-box type, wherein folding flaps of the outer wrapper are connected to one another by thermal tacking and (subsequent) sealing and the outer wrapper is subjected to shrink-wrapping treatment by in particular surface-area heat-discharging mechanisms in the region of mutually opposite surfaces or walls of the pack or outer wrapper—in the case of a hinge-lid box (for cigarettes) a front wall and rear wall, on the one hand, and (upright) side walls, on the other hand—characterized in that surfaces of the packs or walls of the outer wrapper are subjected individually or in pairs, simultaneously or one after the other, to heat and pressure for sealing purposes and/or shrink-wrapping treatment, wherein some walls of the outer wrapper are subjected to a sealing treatment using heat and pressure and the other walls of the outer wrapper are subjected
  • a core of the invention resides in the fact that all the surfaces or walls of the outer wrapper, but at least the front wall and rear wall, on the one hand, and narrow (upright) side walls, on the other hand, are subjected to a shrink-wrapping treatment.
  • the shrink-wrapping operation that is to say the surface-area feed of shrink-wrapping temperature, is combined with the thermal sealing of the folding flaps, to be precise in particular in conjunction with preceding tacking of the folding flaps prior to final sealing.
  • the sealing and shrink-wrapping operations are carried out, according to the invention, in a number of steps, even simultaneously in respect of pack surfaces which are directed transversely in relation to one another.
  • a further special feature is the increase in output of the apparatus, based on packs being fed individually, one after the other, preferably at a distance apart from one another and on cyclic movement.
  • a plurality of (successive) packs are transported together, in the form of a conveying unit, in a conveying cycle.
  • the pack units are moved transversely in relation to the supply direction, that is to say in particular upward, and, in the process, are transported in cyclic fashion through a plurality of processing stations arranged one above the other.
  • the apparatus according to the invention comprises folding mechanisms for the outer wrapper, tacking stations, sealing stations and shrink-wrapping subassemblies. According to the invention, these are no longer arranged, and active, in the order which has been customary up until now.
  • a first shrink-wrapping process follows the tacking of the folding flaps. It is important here for sealing jaws, on the one hand, and also (plate-like) heating mechanisms for the shrink-wrapping treatment to be active in the same station, but to be active on different surfaces or walls of the outer wrapper, said surfaces or walls being directed in particular at an angle of 90° in relation to one another.

  • the examples illustrated in the drawings refer to the treatment of cuboidal packs 10 made of comparatively stiff packaging material, in particular made of (thin) cardboard.
  • the specific example relates to (cigarettes) packs 10 configured in the form of a hinge-lid box or hinge-lid pack.
  • the pack is enclosed on all sides by an outer wrapper 11 made of film which can be sealed thermally—in the region of folding flaps—and can be shrink-wrapped by the feed of heat (shrink-wrapping film).
  • a blank of the outer wrapper 11 is folded around the pack 10 or hinge-lid box to produce a (large-surface-area) front wall 12 , a corresponding rear wall 13 , narrow, upright side walls 14 , 15 and an end wall 16 and base wall 17 .
  • the outer wrapper 11 is folded to produce folding flaps which overlap one another (partially) on one side wall 15 , that is to say flexible-tube flaps 18 .
  • the end wall 16 and base wall 17 are provided with complex folding arrangements (envelope folding arrangement), with trapezoidal closure flaps 19 being formed in the process.
  • the outer wrapper 11 has an opening aid, that is to say a tear-open strip 20 running all the way round.

  • the apparatus shown schematically in FIG. 1 is part of an installation for producing (cigarettes) packs 10 .
  • the latter are transported along a horizontal, essentially rectilinear pack path.
  • the latter is subdivided into portions, that is to say into path portions 21 , 22 which run in the same direction in (vertically) offset planes.
  • the packs 10 coming from a packing machine and, with the exception of the outer wrapper 11 , completed are fed in cyclic fashion and at a distance apart from one another to a folding apparatus, that is to say a folding turret 23 , via an intermediate conveyor.
  • Said folding turret is preferably designed in a manner analogous to the folding turret of EP 1 103 465 A1.
  • the flexible-tube flaps 18 are formed and fixed in tacking fashion by tacking mechanisms 24 (connecting the folding flaps by means of small sealing surfaces).
  • the folding turret 23 is provided with three successive (different) tacking mechanisms 24 .
  • the packs 10 pass into a first region of the path portion 21 .
  • Transportation takes place by an endless belt, that is to say lower belt 25 , which is expediently designed in accordance with EP 2 019 783 B1, that is to say with special drivers 26 , 27 which grip, and thus fix precisely, each pack 10 on the front side—side wall 14 with flexible-tube flaps 18 —and on the rear side—side wall 15 .
  • the packs are transported through a folding route of the path portion 21 in order for the closure flaps 19 to be produced.
  • folding diverters 28 of known construction are arranged laterally alongside the belt 25 , said folding diverters forming the folding flaps 19 during transportation.
  • the packs 10 pass into the region of a further operating station, that is to say a tacking and shrink-wrapping station 29 .
  • a first tacking mechanism that is to say a tacking jaw 30 , is positioned laterally, at a fixed location, partially in the region of the folding diverter 28 .
  • the folding diverter 28 is formed, by a reduction in width, as a lateral guide piece 31 , in order to fix the folding flaps 18 in the folding position until the first tacking operation.
  • the guide piece 31 has an aperture 32 ( FIG. 6 ), through which the tacking jaw 30 or a projecting tacking crosspiece 33 passes until it butts against the end wall 16 or base wall 17 in order to transmit heat and pressure in a limited-surface-area region (tacking).
  • the guide piece 31 is of angled design, as seen in cross section, and therefore the pack 10 is supported on the underside by way of a horizontal limb.
  • the path portion 21 is also designed such that the relatively narrow belt 25 is supported by an elongate path plate 34 , with a central depression for the strand of the lower belt 25 and with lateral supporting crosspieces 35 , on which the pack rests by way of peripheral surface regions.
  • the first tacking jaw 30 is followed by a further tacking mechanism for the sideways directed closure flaps 19 , that is to say by a (relatively long) tacking bar 36 .
  • the latter is dimensioned such that, in one operating cycle, it can act on two packs 10 following one after the other (at a distance apart).
  • the tacking bar 36 supplements or completes the tacking in the region of the folding flaps 19 .
  • the operating surface of the tacking bar 36 is of appropriate design, in the present case with a convex tacking surface 37 .
  • the lateral folding flaps 19 following this processing operation, are fixed to a sufficient extent.
  • the tacking of the folding flaps 19 coincides with a (first) shrink-wrapping treatment.
  • the large-surface-area free pack side that is to say the upwardly oriented front wall 12 (or rear wall 13 ) is subjected to the action of a surface-area shrink-wrapping mechanism, that is to say of a heating plate 38 .
  • the latter can be moved up and down (with very small amplitudes). Heat in the region of the shrink-wrapping temperature is transmitted during the brief full-surface-area abutment against the pack 10 .
  • the heating plate 38 is provided with an aperture or groove 39 on the underside, in the region of the tear-open strip 20 , and therefore the latter is not subjected to heat.
  • An assembly station 40 serves for forming groups or units made up of a plurality of originally successively transported packs 10 .
  • packs 10 form such a processing unit.
  • the packs 10 in the region of the assembly station 40 , are transported transversely in relation to the incoming conveying direction, in the present case in the upward direction.
  • the packs 10 are removed from the common belt 25 and transported further by other conveyors.
  • the present assembly station 40 has a plurality of vertical conveyors, that is to say in each case pairs of vertical belts 41 , 42 .
  • two mutually opposite vertical belts 41 , 42 are assigned to a pack 10 or to a series of (cyclically) upwardly transported packs 10 .
  • Each vertical belt 41 , 42 is guided via upper and lower deflecting rollers 43 (with the drive at the bottom).
  • the belts 41 , 42 have crosspiece-like protrusions 44 , 45 in the form of drives for the packs 10 .
  • the pack 10 which is to be transported is gripped by the protrusions 44 , 45 on the underside and on the upper side, to be precise in each case in a peripheral region adjacent to the end wall 16 and base wall 17 .
  • the vertical belts 41 , 42 and the protrusions 44 , 45 have a smaller transverse dimension than the corresponding dimension (width) of the packs 10 , and therefore at least the side walls 14 , 15 of the packs 10 are fully exposed on either side of the belts 41 , 42 .
  • the vertical belts 41 , 42 are driven together, in cyclic fashion.
  • the conveying movement of the packs by the lower belt 25 is coordinated with the movement of the vertical belts 41 , 42 such that, once a number of packs 10 (four) have been introduced into the region of the vertical conveyor ( FIG. 8 ), the vertical belts 41 , 42 are moved by one cycle, as a result of which the packs 10 are raised off from the belt 25 and fed to a first processing station in the region of the elevator.
  • Processing takes place during the standstill, and therefore four packs 10 can be processed simultaneously, while the same number is fed by the belt 25 in the lower plane, to be precise in conveying cycles of the belt 25 which correspond in each case to the distances between individual packs 10 , and therefore four conveying cycles are necessary in order to provide the appropriate number of packs for being received by the elevator.
  • the side walls 14 , 15 are processed in the region of the assembly station 40 , to be precise in each case the (four) packs 10 of a single unit simultaneously.
  • a strip-like heater 47 gives rise to a shrink-wrapping operation of the side walls 14 , 15 .
  • just the folding-flap-free side wall 15 is subjected to shrink-wrapping heat.
  • a support is provided opposite, in the region of the side wall 14 .
  • the support is a movable supporting mechanism, that is to say a (short-stroke) cylinder 48 , which pushes the pack 10 against the fixed heater 47 for the shrink-wrapping process. This operation takes place at the same time, in the region of the shrink-wrapping station 46 , for all the (four) packs located in the same horizontal plane.
  • the vertical belts 41 , 42 are moved into the next operating station, that is to say into a (first) sealing station 49 .
  • the folding flaps 18 are connected to one another by sealing in the region of the side wall 14 .
  • a special feature resides in the fact that the sealing operation is split up into at least two successive steps.
  • Elongate sealing bodies 50 having a convex sealing surface, for example as in the case of the tacking bar 36 are active in the sealing station 49 .
  • the resulting cross-sectional shape of the sealing body 50 gives rise to a central region of the surface of the side wall 14 being subjected to the necessary (sealing) pressure, wherein the longitudinal edges of the pack remain essentially free of pressure.
  • a (short-stroke) cylinder 48 is arranged opposite the sealing body 50 , and therefore the packs 10 are pushed against fixed sealing mechanisms.
  • a second sealing step is carried out, in the region of the flexible-tube flaps 18 .
  • An elongate sealing body 52 is formed with an essentially planar sealing surface and dimensioned such that the side walls 14 are covered over their full surface area or beyond the same. It is also the case that this embodiment of sealing bodies 52 is assigned a (short-stroke) cylinder 48 in each case.
  • the assembly station 40 is equipped with three operating stations 46 , 49 , 51 , wherein, in each of these stations, simultaneously a plurality of—in the present case four—packs 10 are processed during a standstill phase, the latter lasting approximately four times as long as a standstill phase in the region where the packs 10 are supplied (belt 25 ).
  • the operation of the assembly station 40 is set up such that the packs 10 are transported further at a distance apart from one another, in particular with the previous relative positioning in the form of a unit being maintained in the process. Accordingly, the packs 10 are spaced apart from one another within the unit and from the packs of the preceding and subsequent units.
  • Packs 10 sealed to completion in the region of the side wall 14 are guided into a removal station 53 by a further conveying cycle of the vertical belts 41 , 42 .
  • the packs 10 located horizontally one beside the other, are received by a removal conveyor, an upper belt 54 .
  • the latter is designed in a manner analogous to the lower belt 25 , including the drivers 26 , 27 .
  • the upper belt 54 comprises two correspondingly configured individual belts 55 , 56 .
  • the packs 10 are thus gripped in each case by two drivers 26 , 27 at a distance apart from one another and conveyed out of the region of the vertical belts 41 , 42 ( FIG. 7 ).
  • a further special feature resides in the fact that appropriate transporting movement of the upper belt 54 causes the (four) packs 10 held in the removal station 53 to be transported away simultaneously. Accordingly, the conveying cycle of the upper belt 54 corresponds to the dimensioning of a unit made up of the packs 10 transported away.
  • the packs are gripped between the associated vertical belts 41 , 42 , by drivers 26 , 27 of the upper belt 54 or of the individual belts 55 , 56 , and conveyed simultaneously out of the region of the vertical belts 41 , 42 in the transverse direction. Gaps between the vertical belts 41 , 42 are bridged by horizontal supporting plates 65 .
  • the packs 10 are fed, along the path portion 22 , to further treatment stations, to be precise to a combined sealing and shrink-wrapping station 57 immediately following the assembly station.

  • the heat-discharging plates 58 are dimensioned such that at least the entire pack surface is covered ( FIG. 9 ).
  • the heat-discharging plates 58 also serve for bearing the packs 10 during transportation, wherein the packs 10 slide on the heat-discharging plates 58 .
  • the heat-discharging plates 58 can be moved up and down, that is to say, for carrying out a shrink-wrapping cycle, they can be moved upwards in order to generate a slight amount of increased abutment pressure against the packs 10 .
  • the heat-discharging plate 58 preferably extends over the entire length of the station 57 , that is to say over a length corresponding to (in the present case) four packs 10 .
