Definitions

  • the invention relates to an apparatus for supplying a forming cavity of a ceramic press for producing tiles.
  • the invention further relates to a ceramic slab, in particular a tile.
  • vitrified stoneware tiles and in particular of tiles of large size, i.e. tiles with a substantially rectangular shape having a longitudinal dimension that is noticeably greater than a transverse dimension, that are suitable for covering large surfaces such as those of railway stations, airports, etc.
  • ornamental effects are notably requested that reproduce the veining of natural stone or marble.
  • a drawing comprising veining can be obtained by means of known apparatuses provided with a sliding grid on a sliding plane and moved by a carriage between a loading zone, in which the grid receives from a hopper ceramic powder to be pressed, and a pressing zone in which the grid releases the ceramic powders to be pressed inside a forming cavity.
  • the ceramic powders are previously arranged in the hopper in layers of various colours such that during movement of the grid to the forming cavity the ceramic powders of a given colour become attached to slats, with which the grid is provided, shaped according to the veining that it is desired to obtain.
  • a drawback of known apparatuses is that, in order to produce ceramic tiles having different patterns from one another, the grid has to be dismantled from the apparatus, thus causing the apparatus to stop.
  • the manufacturer of ceramic tiles has to procure a grid for each drawing that he wishes to obtain.
  • Still a further drawback of known apparatuses that use a grid is that in order to obtain the drawing formed by the ceramic powders on the front face of the ceramic tile the surface of the tile has to be polished.
  • the state of the art comprises further apparatuses for supplying a forming cavity for producing ceramic tiles, so-called “double loading” apparatuses, by means of which a layer of decorative material that is suitable for defining a decoration on the ceramic tile is applied to a base layer of ceramic powders during supplying of the forming cavity.
  • a drawback of the aforesaid apparatuses is that it is not possible to obtain longitudinal veining on tiles of big size.
  • An object of the present invention is to improve known apparatuses for supplying a forming cavity of a ceramic press for producing tiles.
  • Another object is to produce an apparatus that enables longitudinal veining to be obtained on a ceramic tile having a longitudinal dimension that is noticeably greater than a transverse dimension.
  • a further object is to provide an apparatus that enables a decoration to be modified that is to be produced on a ceramic tile without it being necessary to dismantle parts of the apparatus.
  • Still another object is to produce an apparatus that enables a decoration to be obtained on the front face of a ceramic tile without having to polish the surface of the tile.
  • Another object is to obtain a ceramic slab of relatively large dimensions having ornamental effects that reproduce the appearance of natural stone such as marble or travertine.
  • an apparatus comprising flexible supporting means, suitable for supporting loose ceramic material to be pressed, containing means arranged for loading said flexible supporting means with said loose ceramic material and further comprising movement means, such as to move said flexible supporting means along a movement direction between a loading position, in which said flexible supporting means is nearer said containing means and a pressing position, in which said flexible supporting means is further from said containing means, said apparatus further comprising driving means such as to drive said containing means along a direction transverse to said movement direction.
  • this forming cavity By supplying a forming cavity of a ceramic press along the movement direction with the apparatus according to the invention, this forming cavity, having a main dimension that extends substantially orthogonally to the movement direction, it is thus possible to form a ceramic tile having a front face, i.e. a face intended to be in view during use, provided with a pattern that reproduces the veining or the blotches of natural stone, such veining or blotches extending longitudinally on the front face of the ceramic tile.
  • a rectangular slab comprising a decoration made of ceramic material pressed into a base body, said slab having a longer edge and a shorter edge having a length of at least 60 cm, said decoration being provided with zones of a colour distributed in said base body substantially parallelly to said longer edge.
  • a zone or a group of said zones is more extended in a direction transverse to said longer edge of a further zone or of a further group of said zones.
  • the colour zones are dispersed in further zones of a further colour and/or of said base body.
  • a plurality of slabs is provided, each slab of said plurality of slabs being rectangular, comprising a decoration made of ceramic material pressed into a base body and having a longer edge and a shorter edge having a length of at least 60 cm, said decoration being provided with zones of a colour distributed in said base body substantially parallelly to said longer edge, characterised in that zones of a colour of a slab of said plurality of slabs are arranged in a different position compared with longitudinally corresponding zones of another slab of said plurality of slabs.
  • said decoration is applied to said plurality of slabs with the same apparatus.
  • the apparatus 1 is provided with movement means comprising in particular a carriage 26 arranged for moving loose ceramic material to be pressed to supply the forming cavity 2 along a movement direction indicated by the arrows F1 and F2 in Figure 1 and in Figure 3.
  • the carriage 26, driven by motor means that is not shown, is movable along the direction F1 between a loading position, illustrated in Figure 1 and in Figure 3, in which the loose ceramic material is loaded onto the carriage 26 and a pressing position, not shown, in which the loose ceramic material is transferred from the carriage 26 inside the forming cavity 2. From the pressing position the carriage 26 returns to the loading position, moving along the direction F2 to be loaded again with loose ceramic material.
  • the loose ceramic material can comprise ceramic powders of various shapes and colours such as atomised powders, granules, chips, frit, glaze and other material.
  • the apparatus 1 enables a plurality of layers of ceramic powder to be obtained inside the forming cavity 2, in particular a base layer and a decorative layer, according to a technique known as "double loading".
  • the base layer defines much of the thickness of the pressed ceramic tile
  • the decorating layer defines a decoration on the front face of the ceramic tile, i.e. the face intended to be in view during use.
  • the ceramic powder intended for forming the base layer is contained inside a base hopper 29 suitable for loading a grid 27 by means of a movable baffle 40.
  • the grid 27, moved by the carriage 26, is slidable on a sliding plane 28 as far as above the forming cavity 2, in which the ceramic powder is deposited.
  • the ceramic powder intended for forming the decorating layer is contained in containing means 4 such as to distribute the ceramic powder on flexible supporting means for forming a layer that is the precursor of the decorating layer.
  • the flexible supporting means may be of continuous type, such as a belt 41 of a conveyor belt 3, or of discrete type, such as sheets, for example of plastics.
  • the belt 41 is wound around a pair of rollers 39, said pair of rollers 39 comprising a drive roller arranged for rotating the belt 41 such that a substantially flat portion of the belt 41 is movable in a direction parallel to the movement direction Fl.
  • the conveyor belt 3 is further moved along the movement direction F1, F2, by the carriage 26 alternatively between the loading position, in which the conveyor belt 3 is nearer the containing means 4, and the pressing position, in which the conveyor belt 3 is further from the containing means 4, in particular the conveyor belt 3 is arranged above the grid 27 at the forming cavity 2. From this position, during motion of the carriage 26 to the loading position, along the direction F2 the belt 41 is rotated so as to pour into the forming cavity 2, above the base layer previously deposited by the grid 27, the precursor layer of the decorating layer.
  • the apparatus 1 can supply the forming cavity 2 as disclosed in RE2004A000097.
  • the containing means 4 is movable along a direction indicated by the arrows T1 and T2, in Figures 2 and 3, transversally to the movement direction F1, F2, alternatively between a first filling position A, illustrated in Figures 2, 3 and 4, and a second filling position B, illustrated in Figures 7 and 8, driven by driving means 20.
  • the driving means 20 comprises a motor 22, a shaft 42 and transmission means 43.
  • the transmission means 43 comprises a transmission belt 23 that can transmit motion to a frame 24 arranged for supporting the containing means 4.
  • an element 44 is fixed that is provided with wheels, which are not shown, that run on a guiding bar 25.
  • the containing means 4 comprises a hopper 5, having an outlet opening 7 for the exit of the loose ceramic material to be deposited on the belt 41.
  • a screening element 8 comprising a frame 9 and an opening 10, for example of rectangular shape, having dimensions substantially corresponding to those of the forming cavity 2.
  • the outlet opening 7 faces respectively a first frame 47 portion 9 and a second frame 48 portion 9, the second portion 48 being opposite the first portion 47 and both portions 47 and 48 being substantially flat and of the same dimensions.
  • the outlet opening 7 extends over a large part of the dimensions of each portion 47, 48, such that the screening element 8 prevents the ceramic powder exiting the hopper 5.
  • the ceramic powder may drop to the conveyor belt 3 by the force of gravity through the opening 10 for forming the precursor layer of the decorating layer.
  • a pair of closing elements is provided, for example a pair of profiled sections, or of sheet metal, each closing element being arranged so as to extend below the outlet opening 7 to close the outlet opening 7 when the containing means 4 is respectively at the first filling position A or at the second filling position B.
  • the screening element 8 is not present and the hopper 5 pours the loose ceramic material directly onto the flexible supporting means.
  • the containing means 4 further comprises a further hopper 11 arranged for pouring ceramic powder through an inlet opening 46 of the hopper 5, the further hopper 11 being provided below with a rotatable baffle 12 of known type, which is drivable by an actuator 13, which may be pneumatic.
  • an actuator 13 which may be pneumatic.
  • the mixer 14 comprises a containing body 15, in the form of an upturned hollow taper with a vertical axis that is open at the bottom inside which a shaft is rotatable that is now shown that is drivable by a motor 16 for mixing ceramic powders of various colours contained therein.
  • the mixer 14 comprises a cover 19 provided with a plurality of inlet ports 17 through which ceramic powders are loaded in the containing body 15 from a known supplying line, which is not shown.
  • a slidable baffle 30 is interposed that enables the containing body 15 to be closed and/or opened from the bottom.
  • the mixer 14 is movable with alternative motion substantially parallelly to the movement direction F1, F2, in a direction indicated by the arrows M1, M2, between a first stopping position C, shown in Figure 9, and a second stop position D, shown in Figure 11, driven by a further motor 18.
  • the mixer 14 receives the ceramic powders from the supplying line and the slidable baffle 30 maintains the containing body 15 closed below.
  • an intermediate motion position G illustrated in Figure 10 during movement of the mixer 14 from the first stop position C to the second stop position D, or vice versa, the slidable baffle 30 opens the containing body 15 below and the ceramic powders are transferred by gravity to the further hopper 11.
  • the slidable baffle 30 can maintain the containing body 15 open whatever the position of the mixer 14.
  • the mixer 14 supplies ceramic powders to the further hopper 11, moving from the first stop position C to the second stop position D, or vice versa, the further hopper 11 being maintained closed below by the rotatable baffle 12.
  • the rotatable baffle 12 is driven and part of the ceramic powders contained in the further hopper 11 are transferred to the hopper 5.
  • the apparatus 1 further comprises further driving means 31 that enables a supporting structure 32 to be raised or lowered with respect to the conveyor belt 3.
  • a supporting structure 32 On the supporting structure 32 there are mounted the supporting means 20, the frame 24 and also the screening element 8, by means of members that are not shown.
  • the containing means 4 is thus movable in an auxiliary direction, indicated by the arrows S1 and S2 in Figure 2, between a raised position E, in which the containing means 4 is further from the belt 41 and a lowered position F, in which the containing means 4 is nearer the belt 41.
  • the screening element 8 Being mounted on the supporting structure 32, also the screening element 8 is driven by the further driving means 31 to move along the auxiliary direction S1, S2, together with the containing means 4, maintaining itself interposed between the hopper 5 and the belt 41.
  • the further driving means 31 is mounted on a base frame 53.
  • the containing means 4 loads the grid 27 and the conveyor belt 3 with the ceramic powders in the manner disclosed below.
  • the containing means 4 In the loading position of the apparatus 1, the containing means 4 is initially arranged, for example, in the first filling position A and the screening element 8 is arranged in the raised position E. From the raised position E, shown in Figure 2, the screening element 8, together with the containing means 4, is lowered to the belt 41, as far as the lowered position F, shown in Figure 5, in which the screening element 8 is at a minimum distance from the belt 41, for example 3 mm.
  • the containing means 4 is driven by the driving means 20 to move along the direction T1 to the second filling position B.
  • the hopper 5 has the outlet opening 7 facing the opening 10 of the screening element 8.
  • the ceramic powders contained in the hopper 5 drop through the force of gravity through the opening 10, occupying a region bounded latterly, at least in part, by the frame 9 and below by the belt 41. Walls 21 of the hopper 5 level the ceramic powders during movement of the hopper 5 between the two filling positions A and B.
  • the containing means 4 stops at the second portion 48 of frame 9 that prevents the exit of further ceramic powder from the hopper 5.
  • the supporting structure 32 is driven by the further driving means 31 to rise such that the screening element 8 reaches the raised position E, shown in Figure 8, in which the frame 9 no longer interacts with the ceramic powders and the precursor layer 49, having a plan dimension that is substantially the same as that of the plan dimension of the frame 9 and therefore of the forming cavity 2, is thus formed on the belt 41.
  • the screening element 8 is further from the belt 41 than the thickness of the precursor layer 49.
  • the conveyor belt 3 is then moved by the carriage 26 to the pressing position, being free to pass below the screening element 8 without interfering therewith.
  • the containing means 4 Whilst the carriage 26 transfers the ceramic powders to the forming cavity 2, the containing means 4 is in a filling position, for example the second filling position B. In this position, the supplying line supplies powders to the mixer 14, which fills the further hopper 11, in the previously disclosed manner. Once the further hopper 11 has been supplied, the rotatable baffle 12 supplies the hopper 5.
  • the containing means 4 already contains the ceramic powders that are required for forming a new precursor layer on the belt 41.
  • the ceramic powders of various colours on the belt 41 such that each colour extends prevalently along the motion direction of the containing means 4, i.e. of the hopper 5. This enables a decoration to be obtained in the decorating layer, and therefore on the front face of the produced ceramic tile comprising streaks, or elongated colour zones, or blotches, that reproduce the veining of marble, and in particular of travertine.
  • a large-size tile i.e. a rectangular tile having a longitudinal dimension that is noticeably greater than a cross section, for example having a longer edge and a shorter edge in which the shorter edge is at least 60 cm, provided with longitudinal veining.
  • the forming cavity for producing large-size tiles is generally arranged such that the longer edge of the tile to be formed is transverse to the movement direction of the carriage.
  • the containing means 4 arranges coloured ceramic powders on the belt 41 along a direction transverse to the movement direction of the carriage, thus creating streaks or veining or elongated zones of colour that are substantially parallel to the longer edge of the ceramic tile.
  • the veining obtained with the apparatus 1 is not traceable to an arrangement of slats of a loading grid of apparatuses of known type, inasmuch as such veining does not show clear but blurred contours.
  • the coloured ceramic powders are transferred from the belt 41 to the forming cavity 2 without substantial alteration of the decoration obtained in the precursor layer.
  • the pattern that is obtained on the front face is substantially the same as that that would be obtained by polishing the surface of the ceramic tile according to known polishing techniques. It is thus possible to obtain a decoration on the front face of ceramic tiles without it being necessary to polish the surface of the tile.
  • a slab 54 of rectangular shape which is obtainable by supplying a forming cavity of a ceramic press with the apparatus 1, has a front face that is provided with a decoration 55 obtained by pressing ceramic powders of various colours in a base body 56.
  • the decoration 55 comprises zones of a colour 57 that extends substantially parallelly to a longer edge of the slab 54.
  • FIG 18 there is shown a further slab 54' of rectangular shape, in which a decoration 55' formed by pressing coloured ceramic powders in a further base body 56' is obtainable by means of the apparatus 1.
  • the decoration 55' comprises wave-shaped zones of a colour 57' the wave having a crest that extends in a direction substantially parallelly to a longer edge of the further slab 54'.
  • elongated zones 58 of a colour in a certain ceramic tile, decorated by preparing the precursor layer 49 on the belt 41, are arranged in a different position from longitudinally corresponding zones of another ceramic tile produced for example subsequently to that certain ceramic tile.
  • the apparatus 1 thus enables a plurality of ceramic tiles to be obtained that are decorated successively, each tile of the plurality of ceramic tiles having a decoration that enables such a tile to be distinguished from other tiles of the plurality of ceramic tiles due to the different arrangement on the front face of the veining, or streaks, or zones of a colour.
  • the tiles of the plurality of tiles are not therefore repetitive inside a common decorative pattern, as occurred in ceramic tiles of the state of the art produced with a grid.
  • the apparatus 1 enables a decoration to be obtained that is substantially repeatable on the ceramic tiles produced.
  • the containing means 4 can arrange a certain colour substantially in a same region of the belt 41, so as to obtain, for example, a streak of that colour having substantially the same dimensions and which extends substantially in the same position on the front face of ceramic tiles produced in sequence.
  • Figures 12 and 13 show an alternative embodiment 5' of the hopper 5.
  • projecting means 34 arranged for interacting with the ceramic powders contained in the hopper 5' to mix them at least partially.
