Definitions

  • Prior-art rotary decorating machines for glaze-patterning tiles use a rotary printing cylinder on which the glaze is loaded and distributed by a transfer roller, predisposed to roll undraggingly on the impression cylinder.
  • the glaze is predisposed on the transfer roller by a further roller rotating contactingly on said transfer roller.
  • each machine works with one colour only, or more precisely with one type only of glaze, so that in order to obtain decorations containing more than one colour, several machines have to be predisposed according to the number of colours required for the finished decoration.
  • the present invention provides a decorating machine capable of actuating a decoration procedure on ceramic tiles in which in a single operation a multi-coloured pattern can be achieved, which pattern is charactenzed by a special blurred effect.
  • figure 1 is a schematic perspective view of the invention.
  • 1 denotes an impression cylinder bearing, engraved into an external cylindrical surface thereof, decorations to be reproduced on ceramic tiles 2 fed to the cylinder by a transport line 12.
  • the printing is achieved by rolling the impression cylinder 1 on the upper surface of the tiles 2.
  • Glaze is deposited on the cylinder external surface by means of a transfer cylinder or roller 3 arranged parallel to the impression cylinder 1 and in contact therewith.
  • a feed group continuously supplies the transfer roller 3 with a sufficient and homogeneous layer of glaze, which is then transferred during relative rolling from said transfer roller 3 to said impression cylinder 1.
  • the feed group comprises a first roller 4 and a second roller 5, reciprocally parallel and in reciprocal contact and rotating in different directions.
  • the second roller 5 is also in contact with the transfer roller 3.
  • the two rollers 4 and 5 together afford a funnel cavity above which three independent feed nozzles 6, 7 and 8 are distributed.
  • the nozzles 6, 7 and 8 are aligned according to a direction which is parallel to the axes of the rollers 4 and 5.
  • Each nozzle is predisposed to dispense a type of glaze in a batched quantity.
  • Batcher devices are provided, denoted respectively by 9, 10 and 11, which on command dispense a precise quantity of glaze to the respective nozzles 6, 7 and 8.
  • a collection tray 13 is positioned below the rollers 4 and 5 and partially below the transfer roller 3, to prevent traces or drops of glaze from falling on the tiles 2 transiting along the transport line 12 before the tiles come into contact with (and are decorated by) the impression cylinder 1.
  • different glazes are conveyed through the nozzles 6, 7 and 8 into the cavity afforded by the upper external surfaces of the rollers 4 and 5.
  • the roller 4, rolling in an opposite direction to roller 5, has the task of distributing continuously on the surface of roller 5 a sufficiently uniform layer of glaze.
  • the roller 5 will be covered with a layer of glaze composed of three different colours. In the edge zones between the colours, that is for example where the glaze from nozzle 6 meets the glaze from nozzle 7, there will be a partial mixing of the colours.
  • a further step is achieved during rolling contact between the roller 5 and the transfer roller 3, where a greater uniformity is achieved in the thickness of the layer of glaze, without altering the composition of the layer itself, which is constituted by three distinct layers of colour.
  • the impression cylinder 1 then distributes the three colours on a tile (when the latter comes into contact with the former) as if they were a single layer of glaze.
  • a layer of glaze is deposited on a tile which layer is composed of a plurality of colours which number depends on the number of nozzles operating above the rollers 4 and 5.
  • the depositing of three colours on a single tile requires three passages, that is three distinct decoration operations performed by three different decorating machines.
  • the invention is therefore especially useful for the production of ceramic tiles having a blurred colour effect.
  • nozzles 6, 7 and 8 are fixed, but embodiments could be realized in which they were mobile, able to be displaced at least in a parallel direction to the roller 4 and 5 axes during normal machine functioning.
  • a further embodiment offers the possibility of effecting the deposit of the pluri-coloured layer of glaze on the transfer roller 3 by means of spray guns, predisposed to operate on the surface of the cylinder itself and appropriately distanced in a longitudinal direction.
  • a variation of colour tone on the tiles can be achieved also in the advancement direction thereof. To obtain this it will be sufficient to feed a single nozzle alternatingly with different glazes.
