Definitions

  • the present invention fits into the technical sector regarding the production of glazed ceramic tiles.
  • the present invention relates to an apparatus and to a method for making, directly on a tiles production line, a kind of artistic decoration, called “third fire” decoration, on glazed tiles, and particularly those produced using the "single-fired” technique.
  • a third-fire treated tile can be moreover provided with recesses and relieves, and it can be made slightly different from each other tile, in order to enhance its characteristics of a hand-crafted and personalized product.
  • a typical production line for single fired tiles comprises a press, fit to obtain a series of raw tiles.
  • the tile surface configuration (or "structure") is obtained by means of a known baren which operates in the press. This structure can be flat, or it may have some roughness, or some recesses and relieves, but each tile is always identical to all the other tiles.
  • Downstream of the press there is a glazing station, which applies a layer of glaze with conventional techniques.
  • Said techniques comprise the using of glazing heads, airbrushes or, in some cases, a particular kind of silkscreen rollers.
  • Some single-firing production lines comprise, upstream of the aforesaid press, a further press, which allows the raw ceramic material to be subjected to a preliminary, slight pressing operation. Downstream of said further press, and upstream of the main press, there are sometimes provided one or more stations for applying a layer of powdery glaze, using spraying or silkscreening devices. When pressed by he main press, this glaze is embedded inside the tile, and it is fixed by the subsequent kiln-drying operation. In this case, the above mentioned main glazing operation may be sometimes omitted.
  • the main object of the present invention is to provide an apparatus for performing the above described "third fire” artistic decoration, particularly on single fired ceramic tiles, directly on their production line.
  • a further object of the invention is to provided an apparatus which is able to make on-line artistic decoration which can be made different on each tile.
  • Another object of the invention is to provide an apparatus for making said artistic decoration with one or more decorating steps.
  • Another object of the invention is to provide a method for making on-line artistic decoration operations on single-fired ceramic tiles.
  • numeral 1 indicates a ceramic tile being processed on a single-firing production line.
  • the tile 1 lays on a belt conveyor 3, of the kind which is commonly used for conveying tiles.
  • An active branch of said conveyor transports the tile 1 between the output of a press 4, wherein it has been formed, and the input of a kiln 5, wherein the same tile has to be subject to a high temperature drying process.
  • the press 4 is provided with a baren fit to give the tiles 1 a base structure. Of course, this base structure is always the same for all the tiles coming out from the press 4.
  • a conventional tiles glazing station Downstream of the press 4 is moreover provided a conventional tiles glazing station, not shown for convenience, for applying a layer of glaze to the tiles 1.
  • This station can be provided with a glazing head or with airbrushes.
  • Figure 1 shows schematically one out of the large number of different configurations that can be assumed by the present apparatus 100.
  • a unique characteristic feature of the apparatus 100, and of the corresponding operating method according to the present invention is that there are one or more operating stations 10,20,30 laying along the path of tiles 1 upstream of the drying kiln 5, said operating stations 10,20,30 being suitable to make decorations on the tiles which define the final decorative aspect thereof.
  • the number of the above operating stations is a function of the decoration complexity, as it will be explained in details in the following.
  • three operating stations are provided, respectively a first station 10, a second station 20 and a third station 30, which are arranged subsequently along the belt conveyor 3, above the tiles path.
  • the first station 10 comprises an operating head 11, whose position is defined by means of a robotized (i.e. position controlled by a computer) driver 13, in a phase relationship with the passing of tiles 1 below the operating area of the same head 11.
  • the robotized driver 13 is fit to define travels of said head 11 across the operating area on the tiles surface 1a, according to a predefined computer program.
  • the robotized driver 13 is provided with three articulated arms 15,16,17, which are independently driven by motor means and capable to give the aforesaid operating head 11 a three-axis moving. That means, the head 11 can be moved along the tile surface 1a and up and down with respect to this latter.
  • the driver 13 is electrically connected to a control unit 40, which comprises a computer running a program which controls the position of each one of the arms 15,16,17 along a series of programmed moving sequences, corresponding to pre-defined paths of the operating head 11.
  • the information corresponding to said sequences is coded and stored inside a computer memory, in a known way.
  • the above paths depend on the kind of decoration which has to be made on each tile 1.
  • the first station 10 comprises, mounted on the operating head 11, an engraving tool 11a, fit to engrave the tile surface 1a according to the aforesaid path.
  • This engraving can be easily made on the tile 1 as it is still soft, because it is not yet kiln-dried.
  • the second head 21 can be programmed such that the device 21a follows the same path of the engraving tool 11a, in order to fill the engraving made by this latter with glaze.
  • the glaze can be a liquid glaze, a powdery glaze or a pasty glaze. According to the glaze type, different decorating effects can be obtained on the tiles 1, more particularly if they are polished after the kiln-drying process.
  • a third operating station 30 is shown in figure 1 and figure 4, and comprises a third operating head 31 mounting a glaze applying device 31 a for powdery or pasty glaze.
  • a glaze applying device 31 a for powdery or pasty glaze.
  • the decorating path can thus comprise a travel along the tile surface 1a as well as a height variation program, in order to obtain on the tile 1 a side-shaded path of variable width.
  • the present apparatus 100 moreover comprises a detecting means 6, connected to the control unit 40, fit to detect the tile position and to synchronize the operating stations 10,20,30.
  • a detecting means 6 are well known in the art, and thus they will no more detailed.
  • All the electronic devices and memory devices that make up the control unit 40 and the drivers 13,23,33 are of known type and commercially available, as well as the programming techniques for driving the operating heads 11,21,31 are well known to medium-skilled engineers.
  • any combination of operating stations can be provided, carrying any kind of tool or any glaze application device, only depending on the number and kind of operation and glaze application, even of different colours, that a designer's fantasy can imagine for decorating a tile.
  • the computer storing capacity allows to store inside its memory a large number of coded information representing different decorating paths, and also allows to vary the decoration for each undried tile passing under the operating stations.
  • the actuating speeds of drivers 13,23,33 and of the computer residing in control unit 40 is moreover abundantly tested to comply with the actual line speed of a production line of single-fired tiles.
  • the present apparatus advantageously allows to make complex decorating operations on single-fired tiles before they reach the drying kiln, without affecting the production line performances.
  • the decorations so obtained can be easily modified and personalized.
  • a configuration variant for the apparatus 100 according to the present invention comes when the production line of single-fired tiles comprises a further press, located upstream of the main press 4 and fit to subject the raw ceramic material to a pre-pressing operation.
  • the conveyor 3 is in this case broken, and carries the forming tile 1 from the above further press to the main press 4, and downstream to the drying kiln 5.
  • operating stations 10,20,30 can be provided both just upstream of the main press 4 and upstream of the kiln 5, in order to increase the number of decorating effects that can be obtained.
