Definitions

  • the present invention relates to a method for the production of packs of rolls of paper with relative carry handle.
  • the present invention is usefully and advantageously applied in the production of packs containing numerous rolls and/or in packs on which the height of the closing side is quite significant.
  • packs of rolls of paper intended, for example, for use as toilet or kitchen rolls is currently carried out using machines designed to: automatically wrap sheets of polythene film, or similar material, around the side surfaces of the rolls arranged neatly in one or more rows; close the front surface of the pack by folding the end flaps of the polythene sheet over the bottom surfaces of the rolls contained in the pack; and finally, seal the folded flaps together.
  • packaging is completed with the application of a strip, again made of polythene or a similar material, whose ends are fixed to the two sides of the pack at one of the two front surfaces and which is long enough to be used as a handle for picking up and carrying the pack.
  • the aim of the present invention is to propose a method for the production of packs of rolls of paper which allows packs to be obtained by wrapping with a plastic film which is folded and sealed, complete with a pack carry handle.
  • Another aim of the invention is to propose a method for the automatic production of packs of rolls which is extremely effective even for packs in which the height of the closing side is significant relative to the width.
  • a further aim of the invention is to propose an apparatus for the automatic production of packs of rolls of paper with sheets of plastic film with an integral pack carry handle.
  • the present invention achieves the above-mentioned aims with a method for the production of packs of rolls of paper, the packs having a substantially prismatic shape, in which the side surfaces are wrapped with a sheet of plastic film and in which one front surface is closed by folding the external flaps of the sheet then sealing the folded flaps to one another.
  • the method is characterised in that the other front surface of the pack is closed with the steps of: using retaining plates to hold the flaps so that they lie parallel with the side surfaces of the pack of which they are respective extensions; bringing the flaps together, allowing them to slide in a controlled way at a tangent to the plates; and gradually inserting between the flaps the side surfaces of the sheet adjacent to them as they are brought together.
  • This pack production method also comprises further steps of stably connecting the flaps joined to one another; and finally, of making an opening in the flaps which can be used as a pack carry handle.
  • the present invention provides an apparatus for the automatic production of packs of rolls of paper wrapped in sheets of plastic film, characterised in that it comprises suction plates, which move vertically in opposite directions, to bring together two opposite flaps of the sheet of plastic film at one of the two front surfaces of the pack, keeping them stretched out opposite one another, with the possibility of sliding at a tangent to these suction plates.
  • the apparatus also comprises: means designed to neatly push the material of the side surfaces of the sheet located between the flaps into the space between the two flaps, gradually as they are brought together, and means designed to seal the two flaps once they have been brought together; and means designed to make an opening in the surface at which the two flaps are joined.
  • the means designed to neatly arrange the material of the side surfaces of the sheet of polythene film in the space between the two flaps as they are brought together advantageously consist of devices which emit air flows with adjustable direction and intensity.
  • the numeral 10 denotes as a whole a pack which has a substantially prismatic shape, containing rolls of paper, for example toilet or kitchen rolls.
  • the pack has two layers of three rolls neatly arranged next to one another.
  • the pack of rolls is already partially wrapped in a sheet 11 of a plastic material, for example a film made of polythene or an equivalent material, preferably in one piece.
  • the side surfaces of the pack 10 and one 25 of the two bottom surfaces are already wrapped, using conventional techniques and apparatus (of the known type and therefore not described in detail here).
  • the other bottom surface 26 is closed using an apparatus which comprises suction plates 12, 13, which move vertically in opposite directions, close to the surface 26 to be closed.
  • the two plates 12, 13 have apertures 14 evenly distributed on their front feed faces 27.
  • the apertures 14 are connected, for example by rods 15 and 16 cables which support and move the plates 12 and 13, to suction means operating with a vacuum which guarantee that the flaps 17, 18 of the sheet 11 which constitute the extensions of the larger side surfaces of the pack 10 adhere between the plates 12 and 13.
  • Adherence between the suction plates 12, 13 and the flaps 17, 18 of the sheet 11 of plastic film is suitably regulated and metered, at the various points of the stroke, so as to allow the flaps 17, 18 to slide relative to the front faces 27 of the suction plates 12 and 13 and, at the same time, hold the flaps 17 and 18 in the stretched configuration opposite one another, as illustrated in Figure 2, to guarantee that the material is neatly arranged between them.
  • the subsequent operation consists of making a central cavity 21 in the layer of plastic material 19, with a shape and dimensions such that it may be used as a pack 10 handle.
  • This operation may be performed, for example, by punching the layer 19 using suitable punches, also obviously known in the sector.
  • the present invention has obvious industrial applications.
  • the advantages in terms of rationality and efficiency of the pack production method proposed are evident, as is the structural simplicity of the associated apparatus, which can easily be implemented in the basic structure of production lines which are already known and consolidated in the sector, such as those operating with the technique in which polythene film is wrapped around packs of rolls.
  • the shape and dimensions of the suction plates 12, 13 may vary according to the dimensions of the pack to be produced and the type of film, and the shape and distribution of the apertures 14 in the plates may vary.
  • the suction means connection to the apertures 14 may be of various types and strengths, according to the applications, and the same applies to the relative adjusting means.
  • the dimensions and positions of the sealing bars and punches used to make the opening 21 may vary.
