Definitions

  • the invention concerns a method for the manufacture of dry-moulded ceramic tiles, with relative moulding plant and tile, namely, a new process of preparing and treating clay-based powders, or ceramic granules, possibly mixed with powdered glazes, and of feeding them into the pressing device, the actual plant where the process is carried out and the ceramic tile obtained thereby also being the object of the present invention, said ceramic tiles being suitable for tiling the inside and outside floors and walls of residential and industrial buildings and of public and private premises in general.
  • the prior art involves moulding methods in which mixtures of granules or clay-based powders, are extracted from a hopper by means of a driven reciprocating grid for transfer to the matrix of the press.
  • Plant for the manufacture of ceramic tiles includes devices for the transfer of mixtures of ceramic granules , or clay-based powders, kaolin, ground glazes, and the like, to the matrix of a ceramic-tile press consisting of a trolley with a grid for the collection and transfer of said mixtures; the trolley being longitudinally mobile with a reciprocating motion along the feeder-board of the press, between a rear loading point corresponding to the outlet for the mixtures from a hopper and a front discharge point, corresponding to the matrix of the press.
  • silk-screen printing is a costly and cumbersome process, particularly in the case of polychrome decoration, when a separate printing device is required for each colour.
  • the decoration obtained by silk screen printing or by application of transfers permeates only a thin surface-layer of the tile; if it is worn off by scuffing or damaged by a blow, the unsightly, undecorated body of the tile is revealed.
  • silk-screen printing and decoration with transfers only allow for the reproduction of a repetitive motif.
  • type of powder is meant to indicate powders of different colours and/or different grain-size, singly or in combination.
  • the feed-apertures referred to at point 2) being defined by borders in any combination of straight and/or curved or mixed lines, which may also form regular geometrical shapes: it being envisaged, furthermore, that the said feed-apertures can be selectively blocked off so as to reduce their output to a greater or lesser extent, thus facilitating the spread of the powders in the die matrix.
  • At least three types of powder are envisaged so as to have streams flowing down a substantially vertical plane divided into layers of powder of different types forming the aforesaid prism-like mass.
  • the feeding of the powders from at least one column being intermittent, in order to obtain, for example, sporadic, randomly-distributed blotches of colour in the tile being moulded.
  • the invention also includes a plant for the dry-moulding of ceramic tiles, consisting of a die fed by a slide, or trolley, that is cranked to and fro along the feeder-board of the die-matrix in order to transport to the matrix itself a predetermined quantity of powders extracted by gravity from the lower outlet of a hopper by means of a grid fixed to said slide; it being envisaged that a multiple powder distributor, having at least two feed-ducts and driven to travel with a horizontal, reciprocating motion, be mounted above the upper loading aperture of said hopper; said grid consisting of a plurality of vertical baffles forming separate, selected feed apertures for the powders and conforming to a motif prefiguring that formed by the distribution of veining in the tile; said baffles presenting in plan view straight lines or broken curves, or any combination of the two, and being oriented with respect to the direction of travel of the slide at an angle of between 0° and 90°: said angle being constant or variable between the baffles and between consecutive sections of each baffle,
  • the tile obtained by this method consisting of a ceramic body obtained by dry-moulding in which the decorative effects of veining, and/or streaking, and blotching, intermingle and penetrate the possibly homogeneous body of the tile to a substantial depth of at least 2mm and even to its very base.
  • the advantages offered by the invention are: the realisation of original, choice and durable aesthetic effects on the tiles,consisting of streaking and veining, and blotching, colour-coordinated with the tile body or in contrast with it; avoidance of repetitiveness in the chromatic effect while preserving the same pattern of veining in the tiles of a given series; moderate cost; modest overall dimensions.
  • Figure 1 is a partly-sectional side view of the plant for feeding the powders to the moulding press
  • Figure 2 is a partly-sectional left view of Fig.
  • Figure 1 is a plan view of the feeder board of the die, in the version for the moulding of one tile per cycle, for example in the format 40 cm x 40 cm;
  • Figure 4 is the enlarged straight cross-section IV - IV of Figure 1 showing the configuration of the conduits in the five-channel embodyment of the multiple distributor, for example for three colours;
  • Figure 5 is a schematic diagram of the distribution of powders in the hopper after a single traverse of the multiple distributor;
  • Figure 6 is a schematic vertical section of the hopper provided with a first embodiment of the distributor having motion orthogonal to the direction of travel of the slide, the hopper showing the stratifying of the powders after to-and-fro traverse of the distributor in Fig.
  • Figure 7 is a cross-section like that of Figure 4 but in the eight-channel embodyment, for example for five colours;
  • Figure 8 is a plan view, from below, of a first embodiment of the grid for extracting the powders from the hopper and transporting the same to the moulding press, with wavy baffles inclined obliquely to the direction of travel of the trolley;
  • Figure 9 is a plan view, from below, of a second embodiment of the grid, with oblique wavy baffles interspersed with blocking elements;
  • Figure 10 is a plan view, from below, of a third embodiment of the grid with the baffles arranged in a pattern of variously-shaped polygons and interspersed with blocking elements;
  • Figures 11, 12, 13 are plan views from below of a fourth, fifth and sixth embodiment of the grid with their geometrical patterns defined, respectively, by parallel baffles, at right- angles to the direction of travel of the trolley, by straight baffles in a criss-cross configuration and by baffles that
  • the figures show: the plant 1 for the preparation of the powders and their transfer to the moulding press 2; the feeder-board 3 of the die of the press 4 along which a slide 5 travels with a reciprocating motion, having a pair of sides 6 designed to slide between longitudinal guides 7 with the interposition of two pairs of opposed rolling elements 8; a device 9 featuring a crank and slotted link for driving the slide 5; a grid 10 for receiving the powders from the lower aperture of a hopper 11 and transporting them in a controlled manner to a die-matrix 12: said matrix advantageously having a base-plate capable of vertical movement between its top position, when it lines up with the feeder-board 3 of the press, and its bottom position, when the matrix is charged before a die-punch 13 descends; a removable frame 14,( Figure 3) of the grid 10, slotted into the front section of the slide 5; a cleaning device 15 for the feeder-board operating after each pressing, comprising a cylindrical rotating brush, pivotally-mounted at the front end of the pair of sides 6: said brush being capable
  • a dispenser 28 of a multiple distributor 29 for the powders Inserted in the upper section of the hopper 11 is a dispenser 28 of a multiple distributor 29 for the powders, said distributor being gravity-fed by means of a plurality of pairs of conduits 30, 31, 32, the upper sections of which are flexible and lead from the containers 33, 34, 35, respectively, of the powders A, B, C: it being envisaged that the quantity of powder in said containers 33, 34, 35, respectively, be kept constant by means of a level-compensating device, comprising, for example, interception valves triggered by level-sensors, not shown, mounted on the feed-ducts of the containers themselves: the pair of central conduits 30 being advantageously connected to a single central conduit 30a in the lower section of the sleeve 36 of the multiple distributor 29.
  • the pairs of conduits 30, 31, 32, converging in the sleeve 36 of the multiple distributor 29, are located centrally, in the case of the pair of conduits 30 destined to carry the powder for the matrix of the tile, and in diametrically-opposite positions, in the case of the pairs of conduits carrying the powder for veining: it being possible for said powders to be of very different, or for example homogeneous, grain-size, or to consist of mixtures of granules and powder, of the same or different colour, or in polychromatic combinations.
  • the pairs of conduits 30, 31, 32 together defining a plurality of columns destined to form the layers of each stream as described in step 1) of the method according to the invention.
  • powders A, B, C flow down a plurality of adjacent streams 33b corresponding to said columns, said streams being separated by ideal sustantially vertical planes 33a: each stream, having a straight rectangular cross-section equal in length to the hopper 11, consisting of superimposed sections of a plurality of layers 33c of powders A, B, C.
  • Layers 33c being defined by ideal planes 50 inclined down in the direction Y of extraction of the slide 5 at an angle that increases as the distance of the generic layer 50 from the lower layer decreases and as the rate of extraction by the slide drops.
  • the figures also show: the depth S of the powders in the hopper 11, advantageously ranging between about 10cm and about 25cm and adjustable by varying the axial position of the dispenser 28 by means of an actuator, not shown: increased depth corresponding to greater degree of mingling between the streams 33b relative to each column; a bracket 37 clamping the ring-shaped projection of the sleeve 36 to a trolley 38 sliding bilaterally, by means of two pairs of opposed wheels 39, on a pair of transverse guiderails 40 fixed to the framework; an enclosed block-chain 41 on a pair of crownwheels 42, one of which driven, having the upper section fixed to said trolley so as to move it: the length of travel L of the trolley being equal to the transverse dimension L1 of the hopper 11 less the transverse dimension L2 of the dispenser 28 of the distributor 29; a plurality of columns D, E, F, G, H of powders, or granules, of different types, singly or in combination, monochrome or polychrome, inserted in respective couples 51,
  • the plan configuration of the baffles 45 prefigures the distribution of the veining in the tile in that it defines the separate feed apertures selected, as described in step 2) of the method according to the invention; the axis Z1 of one of the said baffles forming an angle B1 to the direction Z2 of travel of the grid 10, the term axis being used to indicate the straight line representing the mean inclination of the contour of a baffle or also of only a section of it: the angle B1 being variable between 0° and 180° and capable of remaining constant for the baffles of a given grid or of varying, in a random or repetitive manner, over single or successive sections of any one baffle, so as to create random or geometrical shapes, for instance touching circles 46, ( Figure 13), consecutive squares or parallelograms 47, ( Figure 12), parallel lines 48 ( Figure 11), or whatever is appropriate; blocking elements 49 interposed between adjacent baffles forming zones where the downward flow of powders during the charging of the grid is blocked and such as to cause the powders to spread out when the base of the
  • the axis of symmetry Z3, ( Figure 4) of the straight cross-section of the multiple distributor 29 forms an angle B2 with the direction of travel of the trolley 38: the size of the angle B2 ranging between 0° and 180°.
  • the depth of the baffles 45 determining the load capacity of the grid, is such as to allow a quantity of powder to be collected that is anyway greater than the volume of the layer of powder to be moulded that can be contained in the die-matrix 12 and may even amount to twice that volume, for example.
  • the distribution of the baffles 45 determines the nature of the veining of the tile, for example a diagonal configuration seen in Figures 8, 9 determines a correspondingly-diagonal pattern of veining, while the distribution of the baffles in asymmetrical polygons with varying contours as seen in Figure 10 produces a blotched effect.
  • Veining can be extended to the whole thickness of the tile if the die matrix is charged in a single layer, or be limited to just a part of the thickness of the tile, as when charging with several layers, the minimum thickness being about 2mm.
  • composition by volume: powder A (red) 46% powder B (black) 27% powder C (yellow) 27% grain-size from 0.01 to 1.8mm mean humidity from 5 to 6.5% format 40cm x 40cm
  • the charging of the die matrix 12 is accomplished by the lowering of the base-plate of the matrix when the slide is at the front-stop.
  • the moulding process is as follows: when, by rotation of the crank 24, the slide 5 is recalled from the front-stop position, where charging of the die-matrix 12 takes place, and the back edge of the frame 14 slides under the front edge of the hopper 11, the powder contained in the hopper itself falls by gravity into the separate selected feed outlets 45a formed by the baffles 45 and onto any residue of surplus powder remaining after the charging of said die-matrix: the rate of travel of the slide being coordinated with the rate of fall of the powders so as to effect the gradual replenishing of the grid 10 on its return run; a subsequent rotation of the crank then advances the slide towards the die-matrix and the charging process is repeated.
  • the moulded tiles are then conveyed to the kiln for firing and subsequent grinding, which may take place after laying.
  • the powders are gradually consumed along ideal planes 50, ( Figure 6) inclined forwards and down towards the feeder-board 3 of the press; the reserve of powders being replenished at every cycle by a traverse of the multiple distributor 29, clamped to the trolley 38, over the whole length of the hopper 11; the quantity of powders deposited on each run of the trolley being such as to restore the depth S of powders in the hopper 11.
  • the powders are thus distributed in the hopper 11 in streams 33b built up in layers 33c: the central stream consisting substantially of any powder being introduced in greater proportion, the lateral streams consisting of alternate layers 33c of powders in lesser proportions: the degree of mingling between layers and/or adjacent streams depending on the ratio between the volume of powder consumed at each cycle and the depth S.
  • the multiple distributor 29 may, in addition to running back and forth to restore the depth S of powders in the hopper, be enabled to rotate, continuously or intermittently, around its own longitudinal axis: this makes it possible to achieve aesthetic effects which are further enhanced by the greater degree of mixing between the powders.
  • the dispenser 28 clamped to the trolley 38 must be pivotally coupled to the sleeve 36 on a plane X orthogonal to the axis of the sleeve itself, so as to allow the rotation of the sleeve through a predetermined angle, equal to one rotation or to a fraction of a rotation: it being possible to achieve the rotary action of the distributor by means of a pneumatic cylinder, reduction unit, cam device, or other appropriate means.
  • a second embodiment of the multiple distributor 129 comprises a casing 129a extending substantially the whole width of the hopper 11, said casing enclosing a plurality of substantially vertical conduits 130, 131, 132 alligned along its length.
  • the distributor 129 coupled with driving means 153 has a bottom exit which co-operates with a flow control member comprising a shelf 151, adjacent to the top of the hopper 11, which closes the bottom exit of said distributor when not in operation (operative position in dotted line).
  • the conduits have extendable outlets 130a, 131a, whose position with respect to the bottom exit of said distributor 129 determines the quantity of powders introduced in the casing 129a: by adjusting the position of the extendable outlets it is possible to slightly change the pattern of the tile in a very easy way.
  • the hopper 11 may be provided with a plurality of parallel vanes 152, said vanes are pivotable in order to deflect the flow of powder in substantially separated streams.
