  • the present invention relates to an automatic machine for manufacturing shaped plate-like elements, particularly for packagings, thermal and acoustic insulations, and the like. Summary of the invention The aim of the invention is to provide, an automatic machine which allows to manufacture continuously plate-like elements which are the result of the coupling of a first ribbon of expanded plastic material, which is shaped so as to have undulations of any shape, and is joined to a flat ribbon, which in practice acts as a stabilizing element.
  • an object of the invention is to provide an automatic machine that allows to work at a particularly high speed, without having structurally complicated elements which negatively affect operation of the machine.
  • Another object of the present invention is to provide an automatic machine in which it is possible to considerably simplify all the shaping operations and to achieve very small undulation spacings and heights, obtaining a component which is particularly versatile and functional.
  • Another object of the present invention is to provide an automatic machine which can be easily obtained starting from commonly commercially available elements and materials and is further competitive from a merely economical standpoint.
  • an automatic machine for manufacturing shaped plate-like elements particularly for packagings, thermal and acoustic insulations, and the like, according to the invention, characterized in that it comprises means for the continuous shaping of a first longitudinally moving ribbon, means for arranging a second ribbon laterally adjacent to the shaped ribbon in output from said means for the continuous shaping of a first ribbon, and means for rigidly coupling, at least in discrete regions, said first and second ribbons.
  • Figure 1 is a schematic side elevation view of the automatic machine according to the invention
  • Figure 2 is a front view of the automatic machine
  • Figure 3 is an enlarged-scale sectional view of the detail of an end of the continuous shaping means
  • Figure 4 is an exploded perspective view of one end of the continuous shaping means
  • Figure 5 is a perspective view of one end of the shaping means.
  • the automatic machine for manufacturing shaped plate-like elements, particularly for packagings, thermal and acoustic insulations, and the like, according to the invention comprises a supporting frame 2, on which shaping means are provided, generally designated by the reference numeral 10, for the continuous shaping of a first longitudinally moving ribbon.
  • the shaping means 10, as shown more clearly in Figure 1, comprise a roller with radial fins 11, constituted by a core 12, from which wings 13 protrude which form between them a hollow 14 which extends longitudinally along the roller.
  • the roller with radial fins 11 in practice mates by meshing with insertion bars, generally designated by the reference numeral 20, which are arranged according to a cylindrical configuration and are supported at their axial ends by bell-shaped flanges 25, which are supported rotatably, by means of the interposition of bearings 26, by a rotationally fixed shaft 27.
  • the insertion bars are distributed uniformly circumferentially and are turned by turning means comprising a toothed pulley 28, which is keyed onto the bell-shaped flange 25 and engages a toothed driving belt 29 actuated by motor means, which are not shown on the drawing.
  • the coupling between the bars 20 and the roller 1 is a coupling of the gear-like type, which is designed to insert in the seats 14 a first ribbon 5, which is advantageously made of expanded plastic material and is made to advance along its longitudinal extension.
  • the coupling between the roller 11 and the wings 20 in practice provides an undulation of the first ribbon, which is inserted in the seats 14 formed between the wings 13.
  • motion means are provided for the radial translational motion of the bars 20.
  • Said radial translational motion means for the bars 20 comprise end blocks 30, which are connected to the bars 20 and can slide radially on rods 31, which are supported by the bell-shaped flange 25.
  • the end block 30 is provided with a cam follower roller 32, which enters a cam-shaped track 33 formed on a disk 34 which is keyed to the shaft 27.
  • the cam-shaped track 33 is shaped so as to cause an outward radial translational motion of the insertion bar when two wings 13 couple each other, thus achieving a further insertion of. the first ribbon 5, which in practice forms a bend which is accommodated in the seat 14.
  • the shaft 27 is supported on threaded posts 40, which by engaging a female thread 41 which is rigidly coupled to the end of the shaft 27 produce a translational motion of the shaft 27 in a radial direction with respect to the roller 11, so as to be able to vary the insertion.
  • arrangement means are provided for arranging laterally adjacent thereto a second ribbon 55, which is preferably also made of expanded plastic material; said arrangement means are provided with a feed roller 51, in which the axis is substantially parallel to the axis of the roller 11 and is arranged on supports 52, which allow to vary the radial distance of the roller 51 from the roller 11 depending on the thickness of the ribbons used.
  • the shaping means for the continuous shaping of the first ribbon there are coupling means for coupling, at least in discrete regions, the first and second ribbons, which in a preferred embodiment are constituted by a blower 60, which introduces a jet of hot air in the region for coupling the portions of the first ribbon which remain arranged above the outer ends of the wings 13, which are thus coupled to the second ribbon 50 in regions where the blower 60 in practice provides a localized melting which allows, at the moment of contact, to obtain mutual welding and joining.
  • this type of coupling it is possible to vary at will the type of shaping of the bends that are used; moreover, by modifying the spacing of the insertion bars 20 it is possible to achieve a wide range of types of coupling and shaping.
