Definitions

  • the invention relates to methods for producing packages, in particular cigarette packages, with the features of the preamble of claim 1. Furthermore, the invention relates to devices for carrying out the method.

  • the connection of the folding flaps can be done by means of cold glue and / or by hot melt (hotmelt).
  • hot melt hot melt
  • the longer curing time of the glue joint must be taken into account. During this time, relative displacements of the interconnected folding flaps are possible.
  • the relevant property of hot glue is the comparatively short time for setting.
  • the heat sensitivity of this glue type must be taken into account in the finished packages, for example, heat generation due to solar radiation.
  • the invention relates to the production of packages in which folding flaps are connected to each other by cold glue and / or by hot glue.
  • the problem underlying the invention is to take into account the different properties of the types of glue used in the manufacture of packages, in particular with regard to ensuring exact shapes of the packages.
  • the inventive method is formed with the features of claim 1.
  • the folding tabs are pressed together by active folding measure.
  • An advantage of this method is the attachment of the glue fields, in particular glue points, on both folding flaps to be joined together, ie in particular on the outside of an inner side flap on the one hand and on the inside of the outer side flap on the other hand, preferably in parallel, spaced rows of glue dots. It makes sense to attach the Kaltleima (exclusively) on the outer side lobe, preferably on the downwardly directed inside of these folding tabs in their horizontal starting position. In this case, the hot glue dots are (exclusively) applied to the outside of the inner side flap, which is preferably folded into an upright, pack-like position.
  • the outer side tabs are then, so after application of the glue, formed in an intermediate or prefolding position, in particular at a (acute) angle to horizontal starting position, ie with (small) distance from the associated inner side lobe.
  • Hot glue is applied in the final phase of the movement and completion of the pack, in such a way that the folding flaps are brought into the end position according to the pack before setting the hot glue.
  • the packages are for this purpose - while maintaining the spaced relative position of the folding flaps, but for the exact alignment of the packs otherwise - introduced into pockets of a forming unit. In the area of the pockets then movable folding organs are effective, which fold the outer folding tabs in the end position and press against the inner folding flaps.
  • a special feature relates to the formation of the transport route for the packages during the gluing and (partial) folding, ie the formation of a package web.

  • the movable or pivotable folding lever 52 are actuated so that immediately after the insertion of a pack 10, ie in particular in the lower insertion position, the folding members 52, 54 are effective, so the folding of the outer lobe 13 is completed ( Fig. 7 ).
  • the folding members 52, 54 remain in the folded position during the subsequent rotational movement of the turret 18 to the upper Ausub ein ( Fig. 8 ).
  • the folding lever 52 and the folding heads 54 are withdrawn, so that the packs can be pushed out of the pocket 19 in the manner described by the transverse conveyor 49.
  • the folding levers 52 remain in the retracted position until the introduction of the next pack 10.
  • the support surfaces 74 are presently designed as a radially outer boundary of the recesses 51 and arranged so that the outer lobe 13 - box side tabs 71 and lid side tabs 72 - find a support on the support surface 74, such that the pressure defined by arrow 68 on The support surface 74 is formed with a sloping to the package 10 slope so that the folding process for the outer lobe 13 while maintaining the abutment of the flap edge 62 can be performed on the support surface 74 ,
  • An innovative feature is the coordinated control of the movements of the packs 10 until they are handed over to the forming turret 18.
  • the movements are set up so that the packs 10 are transferred from the pack web 17 to the forming turret 18 or a pocket 19 during one machine cycle.
  • Particularly important is the control of the machine in that the application of the hot glue - hot glue dots 31 -, the feed along the end portion of the package web 17, in particular by the slider 41, and the finished folding of the package 10, preferably in the region of the forming turret 18, during a single Machinery clocks done.
  • the slider 41 is driven by a servo, so it can act independently of the feed of the packs 10 in the remaining region of the packing web 17, in particular with a movement characteristic deviating from the (continuous) movement of the packs 10 in the region of the packing web 17.
  • the autonomy of the conveying movements for the packs 10 allows the application of hot glue even during reduced machine speed and the insertion of the pack 10 in the forming turret 18 at increased conveying speed, so that the package 10 is completed shortly after the application of hot melt.
  • a cold gluing can be omitted.
  • the drive of the slider 41 may alternatively be coupled to the machine drive. Important is the embedding of the gluing with hot glue in a working cycle, which always leads to the completion of the package, namely production of the glue joint.
  • the slider 41 preferably detects the package in a final phase of (continuous) transport through the belt 22, so that the transport of the packages 10 is continued without interruption, preferably with an increased conveying speed. Due to the fork-shaped design of the driver head 42 a collision with the belt 22 is excluded. The slider 41 transports the packs 10 in a (continuous) movement cycle through the gluing station 27 into the end position within the forming revolver 18.
