Definitions

  • This invention relates in a totally general manner to the manufacture of ceramic tiles.
  • the invention concerns the preparation of masses of multiple colour and/or of differing morphology from which to obtain tiles having decorative elements typical of natural stone.
  • the ceramic sector is known to be constantly seeking new and innovative ornamental motifs, with current emphasis on decorations reproducing the appearance of natural stone, such a marble, which knowingly presents generally elongate veining and striations of various forms and colour.
  • the characteristic or most important aesthetic element of said natural stone derives mainly from the randomness with which the form, the extension, the distribution, the colour and the shading of said generally elongate veining and striations are presented.
  • Decorative motifs reproducing said aesthetic element typical of marble can be obtained by the modern ceramic technology involved in the manufacture of fine porcellainized stone, well known to the expert of the art, which will not be described in detail.
  • the main object of this invention is to provide a mixer unit able to prepare base or starting materials by which the tiles leaving one and the same forming press present similar but differing aesthetic characteristics with each pressing, such as veining or striations which differ each time in at least one of the following details: shape, extension, distribution, colour, shading, such as to reproduce the randomness with which such veining is present in natural stone, for example marble.
  • Another object of the invention is to provide a mixer unit presenting a productive capacity such as to satisfy the requirements of modern production plants.
  • a further object of the invention is to provide a mixer unit able to prepare said ceramic starting materials, with said productive capacity, within the context of a simple, rational, reliable and economical construction.
  • a rotary plate above which there are positioned at least two members for dispensing powders having different characteristics, said members being adjustable relative to said plate, with said plate there being associated a fixed hollow cylindrical body for containing said powders and comprising in proximity to said plate at least one material discharge aperture with which there is associated at least one deviator element arranged to convey said powders towards said discharge aperture.
  • Said mixer unit is supported by a movable frame with which suitable drive means are associated in order to move, either continuously or at discrete time intervals, the entire mixer unit above the upper mouth of a hopper for receiving the mixed powders.
  • the said independent drive means consisting for example of a robotized work system or centre, are placed under the control of a processor the purpose of which is to control in a prearranged or random manner the movements of the mixer unit above said hopper.
  • downstream of said continuous discharge system there is preferably provided a secondary fractionating/mixing device able to subject, if necessary or considered opportune, the veined multi-colour mass leaving the cylindrical body to further fractionation and/or more or less intense partial remixing.
  • the quantity per unit of time and the mutual arrangement of the partial streams of said two materials within the moving mass passing continuously through the unit can be randomly varied, so continuously varying the veining of said mass and hence also that of the tiles formed from the starting materials prepared in accordance with the invention.
  • said at least two dispensing members are associated with a known robotized system which varies their position relative to the plate either continuously or at discrete time intervals.
  • a presser member for example a roller, is associated with said plate upstream of said discharge aperture, to compact the powders deposited on the rotating plate by the dispensing members.
  • Figure 1 is the section I-I indicated in Figure 2.
  • Figure 2 is a schematic top plan view of the invention.
  • Figures 3, 4 and 5 show some alternative forms of a part of the invention.
  • Figure 6 is a plan view of a variant of the invention.
  • Figure 7 is a plan view of the frame which manipulates the invention.
  • a gasket can be provided between said plate 2 and the base of the cylindrical body 1 to prevent undesirable seepage or spillage of the material being processed.
  • Each of the dispensing members 3 is arranged to deposit onto the rotating plate 2 the ceramic powders fed to them from overlying ceramic powder supply sources, not shown because of usual type.
  • one of the dispensing members has a circular cross-section whereas the other has a square cross-section, however the cross-section through said dispensing members can be of any shape provided it is suitable for the purpose.
  • the discharge mouths of said dispensing members can also be of different shapes according to the type of powder deposit to be created on the plate 2.
  • said mouths are of circular and square shape respectively, but they can have any other shape.
  • Each of the dispensing members 3 is provided with valve elements 31 provided to vary the powder quantity deposited on the plate 2.
  • the position of said dispensing members on the plate can be adjusted by the operator according to the type of mixing and hence aesthetic effect which is to be obtained.
  • the operator can also vary the height of each dispensing member above the plate to change the manner of delivery of the ceramic powders.
  • the deviator element 13 is in the form of a sector of a cylindrical surface with its axis parallel to that of the body 1, and with its concavity facing the arriving material (see Figure 2).
  • the deviator element 13 could also be shaped as a ploughshare, so that in addition to said plan curvature it also has a curvature transverse thereto, in correspondence with its lower portion.
  • Said device comprises an inclined cylinder provided internally with one or more fins 51' and is rotated about itself by a drive unit.
  • the cylinder is rotated by a belt 52 driven by a gearmotor with an incorporated speed variator.
  • the cylinder can be rotated by other equivalent systems suitable for the purpose.
  • the number, the position, the distribution, the dimensions, the shape and the pattern of said fins 51 can be varied on the basis of the results required.
  • Figures 3, 4 and 5 show some possible forms which the fins 51 can assume.
  • the described unit including the fractionating/mixing device, is supported by a movable frame 40, shown in Figure 7, which comprises a rectangular first carriage 41 supported on two parallel guides 42 via wheels 43.
  • the carriage 41 is operated by usual means. Specifically, on each of the two guides 42 there is fixed a belt 44 and 44', which engage in pulleys 45 and 46 located on the shaft of a gearmotor 48, the operation of this latter causing the carriage 41 to translate along the guides 42.
  • the carriage 41 supports a second carriage 49, substantially identical to the carriage 41, but translating in a direction perpendicular to the direction of translation of the carriage 41.
  • the carriage 49 which supports the entire already described mixer/fractionator unit, comprises a rectangular frame 490 which rests via wheels 491 on two parallel guides 492 rigid with the carriage 41.
  • the carriage 49 is operated by suitable drive means 60.
  • Said means comprise a gearmotor 62 on the exit shaft of which there are fixed two pulleys 62 and 62', each of which engages in a belt 62, the ends of which are fixed onto the guides 492.
  • the entire movable frame 40 is controlled by a processor which provides for moving the entire unit, continuously or at discrete intervals, above the upper mouth of a hopper 200 for receiving the mixed powders, in such a manner as to deposit said powders into said hopper in a prearranged or random sequence.
  • the powders deposited continuously on the bottom 2 are subjected to different remixing operations which can be delicate, more or less consistent, or extended according to the adjustment prevailing at that moment.
  • said dispensing members 3 are associated with a robotized system, not shown as of known type, which during powder deposition on the rotating plate 2 varies, either continuously or at predetermined time intervals, their position relative to the rotating plate in order to diversify the manner of mixing the powders.
  • a robotized system not shown as of known type, which during powder deposition on the rotating plate 2 varies, either continuously or at predetermined time intervals, their position relative to the rotating plate in order to diversify the manner of mixing the powders.
  • at least one roller 100 is associated with said plate, to compact the powder mixture upstream of the discharge aperture 12. Said roller is rotated by a gearmotor 101.
  • the roller can be mounted idle in order to obtain particular aesthetic effects.
