Definitions

  • the present invention relates to an automatic machine for the treatment and transformation of paper by compression with hot moulding and cold material, in particular in which the paper is transformed into products with a common-use volume such as trays, transport packaging, technical components, etc. having a durable consistency and endowed with high mechanical properties of resistance to blows and torsion. For this reason, these products can often replace the same products made of plastic material by means of thermoforming and/or injection.
  • Machines of this type which allow carrying out a process by which paper is transformed into mechanically resistant products, are not known from DE-A1-43 34 364, which discloses a machine according to the preamble of Claim 1.
  • Object of the present invention is solving the aforesaid prior art problems by providing an automatic machine for treating and converting paper which allows to produce a commonly used final product, as indicated above, which is mechanically resistant and has a durable consistency.
  • an automatic paper treatment and converting machine such as the one described in claim 1.
  • Preferred embodiments and non-trivial variants of the present invention form the object of dependent claims. It is understood that all attached claims form an integral part of the present description. It will be immediately obvious that innumerable variations and modifications may be made to what is described (for example relating to shape, dimensions, arrangements and parts with equivalent functionality) without departing from the scope of protection of the invention as appears from the attached claims.
  • the automatic machine 1 of the invention is used to process paper and convert it by hot moulding and cold material compression into products with a common-use volume such as trays, transport packaging, technical components, etc. having a durable consistency and endowed with high mechanical properties of resistance to blows and torsion.
  • This machine 1 substantially comprises, in the direction from left to right with respect to the sheet, which is the direction of unwinding and processing: - at least one reel-unwinding element 3, which is a piece of equipment that supports and unrolls a reel or roll of paper 4; – at least one humidifier element 5, located downstream and operatively connected to the reel- unwinder element 3, this humidifier element 5 being an equipment equipped with sprinklers 6 which spray a solution of water and glycerine at each step onto the flat roll of paper 4 being dragged, moistening it and preparing it for moulding; – at least one first drive system 7, placed downstream and operatively connected to the humidifier element 5: this first drive system 7 is a preliminary drive system which moves the unrolled and humidified paper reel 4 from the humidification zone to the forming zone; – at least one forming press 9, placed downstream and operatively connected to the first driving system 7: this forming press 9 is an electromechanical press with horizontal movement which presses the two halves (male/female, not illustrated) of
  • this system translates the semi-finished product up to the entrance of the two motorized point-guided chain guides 23 which constitute the third dragging system 22.
  • the movement described above takes place through the use of a small pneumatic press 14 which clamps the material formed by milled shapes (which copy the geometry of the formed parts) and performs advance steps programmed by means of a brushless motor 15; – at least one cutting press 16, placed downstream and operatively connected to the second driving system 13: this is an electromechanical press assigned to the perimeter cutting of the previously formed objects.
  • the machine 1 of the invention is also equipped with a control panel 18, consisting of a man/machine video interface which allows the setting, programming and control of the line during the various steps of the production process.
  • the machine 1 described above is the first machine capable of transforming a dry reel of paper into a functional, stable, pleasing to the eye and durable product.
  • the most innovative parts are those in which the dragging of the material takes place, in which the material is moistened and in which the mould works by thermocompression in order to create the desired shapes/geometries.
  • the translation of the dragging material takes place by means of the pneumatic press/plier 14 which crushes the paper material on an "idle" rubber belt: the propelled with a brushless motor programmed to perform a pre-programmed amount of travel.
  • the sprinklers 6 are placed both below and above the roll of paper 4. Furthermore, when the roll consists of a large number of layers, these layers are divided before being humidified to ensure that the paper 4 is also moistened in its deeper layers.
  • a vacuum is applied in the two halves of the mould (upper and lower) to eliminate excess humidity.
  • the mould is heated to about 280°C and the press 9 compresses the material 4 with variable pressure up to a maximum of 250 tons.
