Definitions

  • the present invention relates to a device for automatic and uniform loading of molds of presses for forming ceramic articles, in particular tiles.
  • presses adapted to form tiles; among these, some are of the so-called rotary type, i.e. presses the molds whereof are provided horizontally in a step-by-step motorized rotor assembly; the latter rotates immediately below the pressing assemblies and forms the raw tiles.
  • the abovementioned type of press is operatively very fast, but however requires feeding assemblies for filling the molds, or assemblies for directly spreading dry enamels on the molds already filled with clay or other material. These assemblies must perform this operation in a rapid and uniform manner, filling even the corners of said molds, this operation being heretofore very complicated due to the circular arrangement of these last and to the similar trajectory which they trace during the operation of said press.
  • DE-A-3 151 654 shows a ceramic press having a feeding assembly for filling the molds which includes a sliding distributor arranged above a dispensing frame which is placed above the mold.
  • the sliding distributor receives material from a hopper and slidingly feeds the material to the dispensing frame, while the dispensing frame has a lower bottom constituted by a belt which slidingly opens to thereby feed the material to the mold.
  • the technical aim of the present invention is to eliminate the above described disadvantages by providing a device for automatic and uniform loading of molds of presses for forming ceramic articles, in particular tiles, which is capable of operating at great speed providing, at the same time, the desired accurate and complete filling of said molds.
  • 1 generally indicates a device for automatic and uniform loading of molds 2 of presses 3 for the formation of ceramic articles, in particular tiles.
  • Said device 1 comprises an assembly 4 for feeding material 5, which is constituted by a conveyor belt 6 movable alternately backwards and forwards on related carriages 7 which are slideably guided on horizontal rails 8 or the like and pushed by means 9, preferably of the conventional fluidodynamic type.
  • the output front 6a of the conveyor 6 overlies a small accumulation hopper 10 which is supported by a related framework 11 and has its bottom constituted by three plates, a first upper one 10a, a second middle one 10b and a third lower one 10c, provided with through holes, respectively 12, 13 and 14 with preset diameters, said plates being fitted in sliding contact with one another, the first and third thereof being fixed and the second middle one movable, actuated by related means 15.
  • a small horizontal vibrating grid 16 is provided for spreading the material 5, said grid being moved by related independent elements 17, also coupled to the framework 11.
  • Said means 15 are constituted, in the preferred embodiment, essentially by a fluidodynamic cylinder 18 which has an end 18a rigidly associated with said framework 11 and the opposite end 18b articulated to an edge of the second middle plate 10b.
  • the material 5 is conveyed towards the small hopper 10 by the conveyor belt 6 which is moved backwards and forwards by the conventional fluidodynamic means 9 and is supported, partially protruding, by the carriages 7 which are slideable on the horizontal rails 8 or equivalent devices.
  • the operation of the cylinder 18 is normally controlled by sensors for the passage of the molds 2 below the small hopper 10 and, in a second operation step, the cylinder 18 moves the second middle plate 10b so that its holes 13 are axially aligned with the holes 14 of the third lower plate 10c; in this movement the material 5 accumulated in the abovesaid chambers is progressively carried along and moved towards the holes 14 through which it falls into the underlying mold 2 after passing through the vibrating grid 16 which provides a uniform spreading.
  • the second middle plate 10b acts as bottom for the upper one 10a, closing its holes 12 and allowing the accumulation of further material in the small hopper 10.
  • the cylinder 1 returns the second middle plate 10b to the preceding position, again aligning its holes 13 with the holes 12 of the upper one and thus repositioning itself for the above described operating cycle.
  • the device according to the invention allows the production of new and pleasant chromatic variegations on the surface of the tiles both by intervening, as mentioned, on the diameter of the holes and on their form and/or distribution, and on the loading action of the conveyor 6 into the hopper 10; it is furthermore possible to achieve a deeper interpenetration of said enamels into the material, with consequent production of tiles having a surface colouring thicker and hence considerably more resistant to the wear of time than those currently manufactured.
