Definitions

  • This invention concerns ceramic tile forming processes and the devices for their implementation.
  • porcellainized ceramic stone tiles in which at least the exposed part consists of a bulk-coloured layer.
  • Said layer is formed from atomized clay, the granules of which are variously coloured by known processes, and which are fed to the mould in the form of soft single-colour masses which, on partial mixing, give rise to multi-colour effects reproducing for example marble veining.
  • one of the most delicate points in the porcellainized ceramic stone tile manufacturing cycle is the powder feed to the forming mould cavity, on which the distribution of the powder mass within the tile depends.
  • the known art involves separately preparing, at a point distant from the press, intensely coloured single-colour or two-colour granules or flakes which are then independently stored and subsequently transferred to another vessel mixed with atomized powder, to be then fed to the press hopper.
  • the object of the invention is to prepare and feed said mixtures in such a manner as to avoid said drawbacks.
  • the specific characteristic of the method and apparatus is that the mixtures, including also the flakes, are prepared in a single operation immediately upstream of and in proximity to the press, so dispensing with all the intermediate handling and storage operations.
  • Figure 1 is a partly sectional side view of the invention.
  • Figure 2 is a schematic section through the invention taken on the line II-II.
  • Said figures show a usual press 2 provided with a usual mould 2.
  • a support platform 3 On the side of the press 1 there is a support platform 3 on which a usual loading carriage 4 slides to feed the material to be compacted into the impression in the mould 2.
  • Said loading carriage 4 moves with reciprocating movement between a material loading position and a material discharge position, it being driven by the geared electric motor 5 via the connecting rod-crank mechanism 6.
  • the loading carriage 4 comprises a number of compartments 7 equal to the number of impressions in the mould 2, the compartments being provided with usual internal grids 70. Three compartments are shown in the example.
  • a pusher 8 comprising a scraper 9, to the rear of the compartments there being fixed a flat plate 10, to which the connecting rod-crank mechanism 6 is connected.
  • the loading compartments 7 lie exactly below the lower mouth of the loading hopper 11, whereas when the loading carriage 4 is in the position for discharging the material to be compacted, the compartments 7 lie in correspondence with the impressions in the mould 2, at the same time the lower mouth of the hopper 11 being covered by the flat plate 10.
  • a frame 12 is provided in a position overlying the loading carriage 4, to move continuously to and fro over the upper mouth of the hopper 11, driven by the geared motor 13 via the connecting rod-crank mechanism 14.
  • Said frame 12 upperly supports the service hoppers 15,...,20 and lowerly supports a usual belt conveyor 21 driven by a usual drive, not shown.
  • Each of the hoppers 15, ..., 20 contains a powder of different material characteristics, which is deposited on the conveyor belt 21 to create the superposed material layers thereon.
  • the powder material is fed into each of the hoppers 15,...,20 by a traversing flexible distributor 22,...,27 the lower end of which travels with continuous reciprocating movement along their upper mouths to deposit the material into their interiors in a virtually uniform manner, and which is connected to an overlying vessel by a flexible pipe.
  • Each of the hoppers 15,...,20 is provided with a lower closure gate 28,...,33 operated by a pneumatic unit 34,...,39.
  • Said frame 12 also supports a double-acting cylinder-piston unit 300 fed with compressed air by a compressor, not shown.
  • a frame 301 supporting an idly mounted compacting roller 40 is fixed to the rod of the cylinder-piston unit 300 by known means.
  • the cylinder-piston unit 300 operates in practice as an air spring of adjustable thrust, by which the degree of compaction of the material travelling on the belt between the rollers 40 and 41 can be regulated.
  • the plant operation is controlled by a programmable processor, which coordinates the following operations.
  • the belt 21 is rotated continuously, and collects the respective material from one or more of the hoppers 15 to 18.
  • the material is subjected to the action of the roller 40, which compacts it and crushes the larger-size granules to cause them to assume the desired appearance of irregular flakes.
  • the compacted material Downstream of the compacting roller the compacted material receives single-colour base material from at least one of the hoppers 19, 20, to complete the tile.
  • the movement of the belt 21 is continuous, as is the reciprocating movement of the frame 12, so that several layers form in succession one on another within the hopper 11.
  • the reciprocating movement of the frame 12 is controlled by a level probe provided within the hopper 11, such that the quantity of material present in this latter remains virtually constant.
  • the carriage transfers one material layer at a time having the thickness of the loading carriage into the cavity in the mould 2.
