Definitions

  • the present invention refers to a system for altering the arrangement of the powders forming a strip for the forming of ceramic tiles or slabs.
  • a preparation facility of coloured powders for the forming of ceramic tiles or slabs, comprising a vertical hopper placed above a movable horizontal drop surface.
  • the hopper has a parallelepiped shape with a first pair of faces, called laterals, arranged parallel to the advancing direction of the movable surface and a second pair of faces, front and rear respectively, arranged perpendicular to the advancing direction of the movable surface.
  • the distance between the front face and the rear face is equal to the thickness of the strip of powders to be compacted.
  • the coloured powders are loaded through the opening above and unloaded from the opening below placed at a distance from the movable drop surface equal to the thickness of the strip.
  • the powders are loaded into the hopper in a prearranged manner by means of appropriate feeding means and continuously descend, since they are drawn from the underlying moving surface.
  • Said facility permits not only continuously forming ceramic slabs of the desired thickness by simply varying the distance between the front and rear faces, and, proportionally, that between the unloading opening and the movable surface, but also the realisation of slabs which imitate natural stones, like marble and granite.
  • Object of the present invention is that of providing a system for altering the arrangement of the powders forming a strip for the forming of ceramic tiles or slabs having structural and functional characteristics such to satisfy the aforesaid needs and to remedy at the same time the aforesaid drawbacks.
  • the system comprises a vertical hopper 34 placed above a movable horizontal drop surface 2.
  • the hopper 34 has a parallelepiped conformation with a first pair of faces 34c, called laterals, arranged parallel to the advancing direction (indicated with an arrow) of the movable surface 2 and a second pair of faces 34a,34b, front and rear, respectively, arranged perpendicular to the advancing direction of the movable surface 2.
  • the distance “B" between the front face 34a and the rear face 34b is preferably equal to the thickness "S" of the powder strip 100 to be compacted. Nevertheless, small deviations between said thickness "S" and said distance "B” are possible.
  • the powders 33 are loaded through an opening 37 above and unloaded from an opposite opening 38 below, the latter placed at a distance from the movable drop surface 2 equal to the thickness S of the strip 100.
  • the powders 33 are loaded in the hopper 34 in a prearranged manner by means of appropriate feeding means, not illustrated here for display ease, and continuously descend, since they fall on the underlying moving surface 2. In such a manner, a strip 100 of powders can form on the movable surface 2, reproducing the same prearrangement of the powders 33 present in the hopper 34.
  • the prearranged arrangement of the strip 100 reproduces the typical veining of the natural stones.
  • the system further comprises alteration means of the prearranged arrangement of the powders 33 present in the hopper 34 adapted to operate on the powders 33 before these are transferred onto the movable surface 2.
  • Said alteration means are illustrated in figures 1 and 2 in a first embodiment of the present invention, with an aspirator 11 arranged on the hopper 34 adapted to draw a certain quantity of powder 33 through an opening 20, preferably made on the rear face 34b of the hopper 34. Alternatively, it is possible to make the opening 20 on the front face 34a.
  • the opening 20 is a slit which extends horizontally for the entire width "L" of the rear face 34b of the hopper 34 and can be realised in any position, for example in the lower part (Figs. 1, 1A) or at an intermediate height (Figs. 2,2A) of the hopper 34.
  • Said opening 20 has a height preferably from 5-30 mm and is realised so to prevent the powder 33 from exiting the same.
  • the opening 20 permits the mouth 11a of the aspirator 11 to access the powders 33.
  • such opening 20 is realised as a tilted channel having the lowest part placed inside the hopper 34 and the highest part placed outside the hopper 34.
  • the mouth 11a of the aspirator has a width preferably comprised between 1/3 and 1/10 of the width L of the hopper 34.
  • the alteration means are a drawing bar 12 shaped to be moved into an opening 20' between an external position wherein the opening 20' is closed, preventing the release of the powders 33, and an internal position, represented in figure 3, wherein said opening 20' opens and diverts a certain amount of powder 33 exiting from the hopper 34, through the opening 20' itself.
  • the opening 20' of this second embodiment realised in any position, permits the free release of the powders 33, which is blocked by the drawing bar 12.
  • the drawing bar 12 has a width preferably comprised between 1/3 and 1/10 of the width L of the hopper 34 and the opening 20' has an identical width. Placing the drawing bar 12 in the internal position (Fig. 3), a vacuum is created immediately below it which attracts the powders 33, which descend the sides of the drawing bars 12 and join together below it. This generates, at the exit of the hopper 34, a strip 100 having, at the point wherein it was operated, a clean fracture of the veining which is very similar to the fault separation.
  • the alteration means are an interception bar 13 shaped to be inserted in an opening 20 made in the same manner as the opening 20 described in the first embodiment, and i.e. so to not freely allow the exit of the powders 33.
  • the interception bar 13 creates a vacuum immediately below it which attracts the powders 33 which descend the sides of the interception bar 13 and join together below it. This generates, upon exiting the hopper 34, a strip 100 having, at the point wherein it was operated, a clean fracture of the veining which is very similar to the fault separation.
  • the system for altering the arrangement of the powders forming a strip for the forming of ceramic tiles or slabs according to the present invention permits satisfying the needs and overcoming the drawbacks stated in the introduction of the present invention.
  • the system of the present invention permits obtaining a strip of powders to be compacted for forming a slab reproducing the typical motifs of the natural stones, including the "defects" caused by some natural phenomena such as fault slips.
