Definitions

  • the apparatus comprises a storage station of flat blanks, or die-cuts, made of card material, from which the blanks are fed one by one, translating on a horizontal plane along a feeding direction, to an erecting station.
  • the blank is subjected to the action of a so-called "mandrel” or “mould” vertically movable in a reciprocating manner and consisting in a block having a shape corresponding to the box to be erected.
  • the vertical corners of the box being erected are joined in correspondence with the folding means, by applying lengths of heat adhesive tapes.
  • the mandrel is lifted with the box arranged therearound, the slipping off of the box from the mandrel, and eventually the exit of the box from the erecting station in a horizontal direction, on the opposite side with respect to the feeding side.
  • the blank is usually cross-shaped, or T-shaped or even double-T-shaped.
  • the latter two mentioned formats are the preferred ones in case of deep boxes, i.e. boxes having one or two dimensions greatly prevailing with respect to a third dimension.
  • the above described erecting method may give rise to drawbacks, especially related with accuracy of the result.
  • the device according to the invention is used within a box erecting apparatus having overall characteristics corresponding to those of the prior art (for example of the apparatus disclosed in the Italian patent application mentioned in the introductory part), and thus neither illustrated nor described in detail. It is sufficient to point out that the device is arranged in the erecting station, over the area in which the flat blank F is positioned, awaiting to undergo the action of the mandrel.
  • the latter indicated at 101 and schematically represented only in figures 3a-3h , described in detail further ahead, works moving in a reciprocating manner along a vertical direction Z.
  • the device has a generally quadrilateral framework 1 lying on a horizontal plane, i.e. orthogonal to the axis Z, which delimits a window 2 for the passage of the mandrel.
  • the framework 1 comprises a pair of parallel and spaced fixed crosspieces 3 integral with respective plates 5 connected to the bearing structure of the apparatus.
  • the crosspieces 3 and the plates 5 are omitted in figure 2 for the sake of illustrative clarity.
  • the two crosspieces 3 are elongated in a direction indicated at Y, parallel to the direction along which the flat blank F is fed to the erecting station.
  • Each crosspiece 3 slidingly supports a pair of blocks 6, which in turn bear respective ends of two movable crosspieces 7, square sections elongated in a mutually parallel manner along a direction X orthogonal to the direction Y.
  • the fixed and movable crosspieces 3, 7 thus define the sides of the framework structure 1, delineating the window 2.
  • the sliding of the sliders 8 along the movable crosspieces 7 is then driven by a couple of second motors 15 mounted in cantilever fashion on respective blocks 6 of a same fixed crosspiece 3 (the one on the left in the representation of figures 1 and 2 ), and projecting outwards.
  • Each second motor 15 drives, by means of a transmission belt not shown, a second threaded bar 16 (not represented along one of the two sides, for the sake of clarity, in figure 2 ) extending between one block and the opposed block, and being arranged adjacent to the respective movable crosspiece.
  • the central intermediate region F6 represents the one intended to provide a bottom of the box, from which there will be erected two main flat walls (regions F5 and F7), and two smaller side walls, obtained by overlapping the flaps F1 and F2 (on a side) and the flaps F3 e F4 (on the opposite side).
  • the mandrel 101, and the plate 102 therewith is pushed further downwards ( figure 3g ), making the folding blades slip out of the box and bringing the same box to interfere with underlying fixed folding means 104, arranged in proximity to the end of the run of the mandrel.
  • the folding means 104 may comprise pressure elements working on the side walls to improve the adhesion of the glue, and in any case they have the effect of compacting the box around the mandrel, conferring a stable and accurate form thereto, substantially according to equivalent methods already provided for by the prior art.
  • a further and definite consolidation of the box is also obtained by applying, on the corners, lengths of heat-adhesive tape, according to the known techniques.
  • the blades 9 may be used as actual mechanical and automatic "fingers" to obtain further effects, for example withholding the box when slipping off the mandrel thereof during the final step of the erection, so as to prevent the mandrel itself from withholding the box, due to friction, in its upwards movement.
  • the blades may even be used, after the slipping of the box off the mandrel and before the sideways extraction, to realize a certain shaping of the box, to compensate the natural, slight external bulging of the walls, inevitably present following the folding operations.
  • Such functionalities shall be performed by suitably exploiting the movements of the blocks 6 and the sliders 8, thus such movements, as previously mentioned, also become working and not only adjustment movements.
  • the folding device and method for erecting boxes starting from T-shaped or double-T-shaped flat blanks according to the present invention may be subjected to numerous variants and/or modifications without departing from the scope of protection of the invention itself as defined by the appended claims.
  • the shape of the folding blades, and the respective adjustment/drive systems may undergo even substantial construction modifications, as long as it ensures an equivalent overall functionality.
  • the term "blade” shall not be deemed restrictive, in that generally extended elements capable of ensuring the required folding function may be used.
