Definitions

  • This invention relates to the decorating of ceramic tiles, and in particular to the decorating of large-dimension tiles, by distributing material by free fall onto their exposed surface.
  • Decorating systems comprising distribution means for finishing material intended to cover the upper exposed surface of the tiles which transit below said means on a conveyor.
  • Said systems conceived for covering the tile surface with a layer of vitreous glaze in aqueous suspension, have been gradually improved to enable not only liquid material but also material in powder form to be distributed, with latterly the programmed distribution of several materials having different characteristics.
  • Typical examples are those cases in which two different finishing materials are distributed which on falling onto the uncovered portions of the conveyor partially mix together.
  • the object of the present invention is to remedy the said drawbacks by providing a decorating system in which the tiles are made to advance continuously and uniformly along a conveyor below one or more distributors providing free fall of finishing material, said system operating without soiling the line while at the same time enabling complete recovery of any finishing material which has not been collected on the tiles.
  • the conveyor is constructed as coplanar sections separated from each other by interruptions which correspond to the regions onto which the finishing material is made to fall.
  • the number of interruptions must be at least equal to the number of overlying free-fall distribution means for the finishing material.
  • Figure 1 is a schematic side view of one embodiment of the invention.
  • Figure 2 shows the section II-II of Figure 1.
  • a conveying line 1 for tiles 2 feeds an alignment of tiles preferably but not necessarily spaced equally apart, to a decorating system 4.
  • This latter comprises a bench 5 which supports an overlying flat conveyor 6 consisting of a series of equidistant motorized rollers driven by an underlying common belt 8, 81
  • two belts 8 and 81 are shown, symmetrically disposed on each side of the conveyor and driven respectively by two geared motors 82 and 83 after conveniently passing about suitable pulleys.
  • finishing material distribution devices of known type, arranged exactly above the space defined between two adjacent rollers 7.
  • transverse trough 10 which collects the material falling from the overlying distribution device 9.
  • the trough 10 is supported in a laterally open seat 11 provided in a lower protection plate 12; specifically, the trough 10 comprises two flanges 13 which rest on the edges of said seat, and can be withdrawn by lateral sliding.
  • the invention can also be implemented in other ways, for example by making the conveyor in the form of a succession of belt conveyor segments of usual type, separated from each other by a space enabling the finishing material distributed by an overlying device 9 to pass through.
  • each distribution device 9 can distribute material different from the material of the other devices, and is provided with closure means, of which the times and manner of opening are controlled by a programmable processor which enables different decorative effects to be obtained on the tile.
