Definitions

  • the present invention relates to a method for the digital decoration of ceramic tiles.
  • the digital machines for decorating ceramic tiles of known type generally comprise a bearing frame to which is associated a supporting surface of one or more ceramic tiles mobile along a forward direction.
  • Such machines then comprise a tile decorating unit placed above the supporting surface and having a plurality of digital printing heads.
  • the decoration unit of digital machines of known type can be of two types, to each of which types corresponds a different decorating method.
  • the decoration unit supports a printing head for each colour to be dispensed and is mobile during the printing operation to cover the whole surface of a ceramic tile to be decorated.
  • the movement completed by the decoration unit of this first type is of the type of a plotter for printing on paper, where, during the decoration phase, the heads move with respect to the surface to be decorated so as to fully cover such surface.
  • This type of digital machine thus contemplates the continuous movement of the relative decoration unit, with a consequent high mechanical stress of the elements kinematically coupled together.
  • the decoration phase is fairly slow considering the ink jet dispensed by the heads is able to only cover a minimum part of the tile to be decorated and that the heads themselves must move along two directions at right angles to each other to cover the entire surface to be decorated.
  • the decoration unit has a plurality of rows of heads for digital printing, where such rows are arranged crossways to the forward direction of the tiles and each of them is suitable for dispensing a specific colour.
  • the decoration unit and each individual head are stopped during tile decoration. More in detail, depending on the size of the tile to be decorated, the area of decoration changes within which the glaze has to be dispensed from the heads to reach any point of the tile itself.
  • the decoration unit therefore has active heads suitable for dispensing glaze inside the decoration area relating to the tile to be decorated without the treed to move the decoration unit itself at all.
  • the number of active heads varies relating to each colour and which are then used during the decoration process.
  • the heads suitable for dispensing outside such decoration area are on the other hand inactive, i.e., they do not take part in the decoration process.
  • the tile to be decorated being a large-size tile, such as a 700x700 mm tile, such therefore as to substantially occupy the entire transversal overall dimensions of the supporting surface
  • its decoration is done using practically all the heads of each row of the decoration unit, in such a way as to cover the entire surface of the tile itself.
  • the tiles to be decorated being of smaller size, such as a 300x300 mm tile (currently corresponding to one of the most common sizes)
  • the heads are used arranged in the proximity of the central area of the supporting surface, i.e., only the heads arranged above the area where the tile transits.
  • This type of digital machine, and therefore the relevant decorating technology also has a number of drawbacks.
  • the inactivity of a number of the printing heads which occurs while decorating medium-small size tiles and which sometimes continues for long periods of time, results in these, at the time of their reactivation following a sire change, ether not working or else producing a decoration different with respect to the heads that have always remained active and which therefore, have a different degree of wear.
  • the replacement of the digital printing heads is very costly from an economic viewpoint and also produces long machine down times, causing an increase in the cost of the end product and a reduction in the output of the machine itself.
  • the main aim of the present invention is to provide a method for the digital decoration of ceramic tiles, and a machine able to implement such method, which allows exploiting in a substantially homogeneous way all the heads of then decoration unit whatever the size of the tile to be decorate.
  • One object of the present invention is therefore to optimise the use of all the printing heads in order to obtain an amount of wear more or less constant on all the heads and therefore a substantially uniform decoration over time.
  • Another object of the present invention is to extend the life of the printing heads, thereby avoiding their premature replacement and improving the payback on the investment relating to the machine itself,
  • Yet another object of the present invention is to increase the output of the machine, reducing machine down times in a specific period of time.
  • Another object of the present invention is to provide a method for the digital decoration of ceramic tiles that allows to overcome the mentioned drawbacks of the state of the art in the ambit of a simple, rational, easy and effective to use as well as low cost solution.
  • the present objects are achieved by the present method for the digital decoration of ceramic tiles according to claim 1.
  • reference number 1 globally indicated by reference number 1 is a digital machine for the decoration of ceramic tiles.
  • the machine 1 comprises a bearing frame 2 arranged resting on a reference surface and having a supporting surface 3 for supporting one or more ceramic tiles P', P" mobile along a forward direction identified in the illustrations by the arrow 4.
  • the surface 3 is defined by a plurality of belts 5 arranged parallel with one another and at a distance from one another.
  • the belts 5 are mobile along the forward direction 4.
  • Different embodiment cannot however be ruled out in which the surface 3 is defined by a different movement system such as, e.g., a continuous belt.
  • the machine 1 also comprises at least a decoration unit 6 arranged above the surface 3 and comprising a plurality of heads 7',7" for digital printing on the ceramic tiles P' P".
  • the heads 7',7" are electronically controlled by a command and control unit, not shown in the illustration, which controls their operation.
  • At least a part of the heads 7',7" can be activated to dispense glaze in correspondence to a decoration area 20 defined on the surface, 3 and facing the decoration unit 6 so as to reach any point of the tile P', P" to be decorated.
  • the decoration area 20 substantially corresponds to the area of the surface 3 intercepted by the tile P', P" during its movement along the forward direction 4.
  • the size of the decoration area 20 therefore varies according to the dimensions of the tile P', P" to be decorated and to its position on the surface 3. More in particular, depending on the size of the tile P', P" to be decorated, the width varies of the decoration area 20 considered as dimension transversal to the forward direction 4.
  • the decoration unit 6 has one or more heads 7' which can be operated to dispense glaze in correspondence to the relative decoration area 20, and which are defined as active heads 7' in the present treatise, and one or more heads 7" able to dispense glaze outside the decoration area 20, and which are defined as inactive heads 7" in the present treatise inasmuch as they do not take part in the decoration phase of the tile P',P".
  • active heads is therefore used to identify all the heads of the decoration unit 6 which take part, from time to time, in the decoration phase of a tile P',P" and which are therefore able to dispense glaze in correspondence to the relative decoration area 20; similarly, the term “inactive heads” is used to identify all the heads of the decoration unit 6 which do not take part in the decoration process and, therefore, remain inactive as the term itself suggests.
  • the number of active heads 7' and their arrangement with respect to the decoration area 20 can be preset by an operator according to the size to be decorated or, alternatively, can be automatically identified by the command and control unit which is operatively connected to sensor means suitable for detecting the dimensions of the tile P',P" and therefore of the relative decoration area 20.
  • the active heads 7' therefore belong to an active area defined on the decoration unit, while the inactive heads 7" are arranged outside such active area, Preferably, such active area corresponds to the projection of the decoration area 20 on the decoration unit 6.
  • Different embodiments cannot however be ruled out wherein the dimensions of the active area in correspondence to which are arranged the active heads 7" which dispense glaze during the decoration phase are different with respect to the dimensions of me decoration area 20.
  • the heads 7',7" are grouped in several rows 8 arranged substantially parallel the one to the other and which extend along a direction transversal to the forward direction 4.
  • each row 8 comprises at least one active head 7' and at least one inactive head 7" able to dispense glaze in correspondence to and outside the decoration area 20 respectively.
  • each head 7',7" comprises at least a nozzle for dispensing the glaze on the tile P',P", not visible in detail in the illustrations, and a relative electronic part 7a, which can be operatively connected to the command and control unit and is suitable for commanding the dispensing of ink through the nozzle of the corresponding head 7',7". More in particular, the nozzles of the heads 7',7" are arranged substantially facing the supporting surface 3 and the relative electronic parts 7a are arranged above the corresponding nozzles.
  • the machine 1 also comprise a plate 9 having one or more openings for fitting in the heads 7',7" and which defines a first face substantially facing the surface 3 and in correspondence to which protrude the nozzles and a second face in correspondence to which the electronic parts 7a are arranged.
  • the decoration unit 6 is mobile in translation with respect to the surface 3 along at least a first direction, identified in the illustrations by the double arrow 10, transversal to the forward direction 4 and substantially parallel to the surface 3, to change the position of the heads 7',7" with respect to the decoration area 20 so as to modify at least in part, between two subsequent decorations, the active heads 7' able to dispense glaze in correspondence to the decoration area itself.
  • the decoration unit 6, which is stopped during the decoration phase, is therefore mobile along the first direction 10, between two successive decorations, to selectively change the active heads 7' able to dispense glaze in correspondence to the decoration area 20 of the relative tile P',P" to be decorated.
  • the movement of the decoration unit 6 is suitable for moving at least one of the inactive heads 7" arranged outside the active area relating to the first tile P'' in correspondence to the active area relating to the second tile P".
  • the movement of the decoration unit 6 is suitable for changing the position of the heads 7',7" with respect to the active area of a relative tile P',P" as well as with respect to the decoration area 20.
  • the movement of the decoration unit 6 along the first direction 10 thus causes the active heads 7' and the inactive heads 7" relating to the decoration of a first tile P' to be different with respect to those relating to a second tile P" fed after the first tile itself.
  • the decoration unit 6 is mobile along the first direction 10 between at least a first and at least a second operating position, where the active heads 7' in the first operating position are at least in part different from the active heads 7' in the second operating position.
  • the first direction 10 is substantially parallel to the direction of extension of the rows 8 of the heads 7
  • the first direction 10 is substantially perpendicular to the forward direction 4.
  • the decoration unit 6 is mobile along both the sides defined by the first direction 10, as indicated by the bidirectional arrow shown in the illustrations.

  • the first nut screw 11b therefore translates along the first direction 10 due to the rotation of the first screw 11a around its axis.
  • the first screw 11a extends longitudinally along the first direction 10.
  • the first nut screw 11b is connected sliding to the frame 2 along the first direction 10 while the first screw 11a is integral in translation with the frame 2.
  • the machine 1 also comprises a supporting structure 12 of the decoration unit 6 which is associated sliding with the frame 2 along the first direction 10.
  • the first screw nut 11b is therefore associated integral with the supporting structure 12.
  • the slide 13 comprises a runner 13a associated integral with the supporting structure 12 and which cooperates with a fixed guide 13b, associated integral with the bearing frame 2.
  • the machine 1 comprises first starting means 14 of the first movement means 11.
  • the first starting means 14 can be of the manual and/or electro-mechanical type.
  • the first starting means 14 comprise at least a first electric motor 14a , mechanically linked to the first screw 11a.
  • the first motor 11a is connected to the first screw 11a by means of a reduction device, e.g., by means of a belt drive.
  • the first starting means 14 also comprise a first pulley 14b, associated integral in rotation with the exit shaft of the first motor 14a, and a second pulley 14c, associated integral in rotation with the first screw 11a, linked together in rotation by means of a belt 14d.
  • the first drive pulley 14b has a smaller diameter than the second driven pulley 14c, so as to achieve a reduction of the rotation speed from the first motor 14a to the first screw 11a.
  • the first motor 14a is associated integral with the frame 2 and, consequently, it is fixed with respect to the supporting surface 3.
  • first starting means 14 comprise, alternatively or in addition to the first electric motor 14a, also manual means mechanically linked to the first screw 11a, suitable for allowing a manual adjustment of the position of the decoration unit 6 with respect to the surface 3 along the first direction 10.
  • the decoration unit 6 is also able to move closer/away from the surface 3 along a second direction, identified in the illustrations by a double arrow 15, crossways to the first direction 10.
  • the second direction 15 is substantially perpendicular to the first direction 10.
  • the second direction 15 is substantially perpendicular to the forward direction 4 and to the supporting surface 3.
  • the decoration unit 6 is integral in translation with the supporting structure 12 along the first direction 10 and is mobile with respect to this along the second direction 15.
