Definitions

  • the invention relates to a press loading device for manufacturing ceramic tiles.
  • the invention also relates to a press equipped with a loading device as well as a method for loading a press for manufacturing ceramic tiles.
  • Italian patent nr. 1,280,079 describes a loading device of the type comprising a trolley with reciprocating movement for taking powder from a main feeding hopper and for transferring the powders to at least one press die-matrix; and wherein the trolley has at least one loading grid, which is filled with powders to transfer the powders to the die-matrix or die-matrixes of the press.
  • Italian patent nr. 1,287,772 describes a device for feeding powders or sand into a press die-matrix loading grid for manufacturing tiles.
  • various powders are unloaded in a controlled fashion by a set of hoppers onto a slanted chute. From here, the powders fall into an elongated hopper which develops transversely with respect to the direction of movement of the press die-matrix loading grid. From the hopper, the powders are unloaded into the underlying grid at each loading cycle. Special decorative effects on the finished tile are obtained by overlaying several layers of various colored powders on the slanted chute and unloading them from the feeding hopper to the loading grid.
  • European patent nr. 605930 describes a method and device for loading powders into die-matrixes for the production of tiles.
  • the device consists of a powder feeding system from a plurality of overhead containers via a plurality of tubes. Veining of powder of various colors is formed in a distributor which feeds the lower grid, which can be formed by variously shaped baffles, whose shape may be irregular.
  • Object of the invention is to realize a loading device for manufacturing ceramic tiles with veining similar to that of stone, that is randomly distributed, as characteristically occurs in natural materials.
  • the invention provides a loading device which is capable of depositing small amounts of suitably coloring powders (atomized, micronized or other) in the die-matrix loading grid of the press during the return phase of the grid from the press.
  • the device according to the invention comprises an auxiliary hopper arranged downstream to the main feeding hopper - with respect to the direction of advancement of the trolley from the loading area to the die-matrix - and developing transversally with respect to the direction of advancement of the trolley.
  • the auxiliary hopper is equipped with a distributor for distributing a controlled amount of at least one coloring powder into the loading grid during the return travel of the grid from die to the main feeding hopper.
  • the invention also relates to a method for manufacturing ceramic tiles comprising the following phases:
  • the loading device comprises a trolley 3 reciprocatingly mobile in the direction of the double arrow f3 from a loading position, illustrated in Fig. 1, where the powders are loaded onto the trolley, to a filling position of one or more die-matrixes of a press, generically indicated by reference numeral 5.
  • the press 5 presents a double die.
  • Each die is equipped with a lower punch (indicated by references 7A and 7B for the two dies, respectively) and an upper punch (indicated by references 9A and 9B).
  • References f7 and f9 indicate the upwards and downwards movements of the lower punch and the upper punch, respectively.
  • each loading grid 11A, 11B essentially corresponds to the dimension of the respective matrix and is formed by a number of baffles, indicated by reference numeral 12, whose shape is irregular and generally curved.
  • auxiliary grids Two corresponding auxiliary grids, indicated by references 13A and 13B, are arranged in front of each loading grid 11A, 11B, i.e. between the grids and the press 5, for the purposes described below.
  • the grids 13A, 13B are formed by straight baffles 14, whose development is orthogonal to the direction of movement (arrow f3) of the trolley 3.
  • a main feeding hopper is arranged in the loading station, where the trolley 3 is found in the arrangement shown in Fig. 1.
  • the main feeding hopper 17 is developed in the orthogonal direction with respect to the direction f3 of movement of the trolley 3 and is subdivided into two parts to feed powders to the two grid pairs 11A, 13A and 11B, 13B respectively.
  • a chute 18 is arranged over the main feeding hopper 17, onto which powder from one or more overhead containers 19A, 19B, 19C is fed; each container is equipped with a rotary valve 20A, 20B, 20C or other suitably controlled metering means.
  • a respective auxiliary hopper is arranged downstream with respect to the main hopper 17 between the main hopper and the press 5 for each pair of grids 11A, 13A and 11B, 13B; the auxiliary hopper presents a longitudinally elongated development with a lower unloading mouth whose length is equal to the width of the respective grid 11A, 13A or 11B, 13B.
  • Each hopper 31 is subdivided by a longitudinal intermediate partition 32 into two compartments 31A, 31 B.
  • Two distributors 35A, 35B - which receive powders via conduits 37A, 37B connected to overhead containers 39A, 39B - lead to each of the compartments 31A, 31 B of the two auxiliary hoppers 31.
  • the distributors 35A, 35B have elongated unloading apertures according to the longitudinal development of the auxiliary hoppers 31 so to distribute the powders along the entire longitudinal development of the compartments 31A, 31B of the hoppers 31.
  • the four containers 39A, 39B can contain reciprocally different powders or only two types of powders so that the two hoppers 31 each receive the same two types of powders in the two compartments 31A, 31B into which they are subdivided.
  • auxiliary hoppers 31A, 31 B can be loaded with different loading methods because the method used to introduce the material into the hoppers 31A, 31B is not relevant for the purpose of the present invention and neither is the method for filling the grids with basic material from the main hopper 17.
  • each auxiliary hopper 31 is closed by a respective distributing valve 41 with two unloading apertures 41A and 41B.
  • the apertures 41A, 41B can have a continuous longitudinal development equal to the length of the respective auxiliary hopper 31, or be subdivided into slots whose length is shorter than the total longitudinal development of the auxiliary hopper 31.
  • Two cylinder-piston actuators or other type are arranged on the ends of each auxiliary hopper 31 to control the movement of the distributing valve 41 according to the double arrow f41.
  • the distributing valve 41 may assume one of the three positions shown in Figs. 1, 2 and 5D, respectively.
  • the distributing valve 41 is in a position that closes the unloading mouth of the respective auxiliary hopper 31. This is because the apertures 41A, 41B are exactly under the compartments 31A, 31B into which the auxiliary hopper 31 is subdivided and over a lower closing plate 45.
  • the apertures 41A, 41 B are completed closed by the plate 45.
  • the distributing valve 41 is moved to the right with respect to the intermediate position assumed in Fig. 1. In this way, the inner compartment 31B of the auxiliary hopper 31 can unload a small amount of powder material through the aperture 41B in the distributing valve 41 downwards. In the arrangement shown in Fig. 5D, on the other hand, the distributing valve 41 is moved leftwards and puts the inner compartment 31A of the respective auxiliary hopper 31 into connection with the outside to unload the material therein contained.
  • each distributing valve 41 can be moved and arranged on a slant, also only of a few degrees, with respect to the middle plane of the respective auxiliary hopper 31. In this way, the width of the material unloading aperture may be varied along the longitudinal development of the hopper 31, to unload a variable amount of material from one end of the hopper to another hopper 31, for the purposes which will be illustrated in detail below. Furthermore, the valves 41 of the two auxiliary hoppers 31 can be controlled independently one respect to the other.
  • each auxiliary hopper 31 is equipped with scrapers 47 that prevent the accidental, undesired output of material and the reciprocal mixing of powder in the two internal compartments 31A, 31B.
  • the loading grids 11A, 11B and the auxiliary grids 13A, 13B are filled with powder material mainly fed from the main hopper 17 and - for the main grids 11A, 11B - with a minimum amount from the auxiliary hoppers 31, as described below.
  • the loading grids 11A, 11B are positioned exactly over the lower punch 7A, 7B of the press 5.
  • the lower punch is in line with a sliding surface P which extends from the trolley loading area to the press dies and from there to a conveyor belt 51 for removing the manufactured tiles.
  • the powders contained in the loading grids 11A, 11B and in the auxiliary grids 13A, 13B cannot fall out of the grids.
  • the front part of the trolley 3 has pushed the tile P1 formed during the previous cycle from the pressing area onto a conveyor belt 51 which carries it to the oven.
  • the lower punches 7A, 7B can be moved down to reach the position in Fig. 5B. Consequently, the powdered material contained in the loading grids 11A, 11B is integrally unloaded into the two press matrixes, on top of the upper surfaces of the punches 7A, 7B. The matrixes are not entirely filled, as can be seen in Fig. 5B.
  • the powdered material contained in the auxiliary grids 13A, 13B remains inside, due to the presence of the sliding surface P which closes the lower part of the auxiliary grids 13A, 13B.
  • the height of the loading grids 11A, 11B is chosen so that the powder material therein contained is entirely unloaded into the two matrixes of the press 5 whereby entirely emptying the loading grids 11A, 11B.
  • the powder material therein contained is not sufficient to entirely fill the press matrixes and the empty spaces are entirely filled with the material contained in the auxiliary grids 13A, 13B during the return stroke of the loading trolley 3, as shown in Fig. 5C.
  • auxiliary grids 13A, 13B are never entirely unloaded during this phase to ensure the complete filling of the matrixes of the press 5. In other words, the total of the powder material in each pair of grids 11A, 13A and 11B, 13B exceeds the amount of material needed to completely fill the respective press matrix.
  • the trolley 3 passes under the auxiliary hoppers 31 (Fig. 5D).
  • Each hopper 31 is opened, by a controlled movement in either one and/or the other direction of the distributing valve 41, to unload a small amount of powder material from one of the two compartments (or in sequence from both compartments) 31A, 31B of each auxiliary hopper 31 into the space defined by the baffles 12 of the respective loading grid 11A, 11B.
  • a minimum amount of the material is distributed on the bottom of the grids 11A, 11B next to the curved baffles 12, as shown in particular in the schematic magnification of Fig. 6.
  • the material unloaded from the auxiliary hopper 31 into the loading grid 11A or 11B is accumulated next to the baffles of the grid and is schematically indicated by references V1, V2, V3, V4.
  • the amount of material is minimal with respect to the total loading volume of the grids 11A, 11B and is distributed next to the baffles 12 forming the grids 11A, 11B by effect of the movement of said grid.
  • a sort of veining whose pattern is defined by the curved baffles 12 of the grid, is formed.
  • line F1 represents the relative position in a temporal instant and that this position changes slightly in time due to the movement of the trolley and the grid 11A, 11B before closing the feeding slit. This movement will not be considered in the description that follows for the sake of simplicity.
  • the powder unloaded from auxiliary hopper 31 in position F1 is accumulated against the first curved baffle 12 and forms continuous veining V1.
  • the powder unloaded from the auxiliary hopper 31 in position F2 accumulates against the two different curved baffles 12, forming broken veining V2.
  • the veining V2 is broken in the point where the line F2 crosses the baffle indicated by reference 12A.
  • the powder unloaded from position F3 forms veining V3, subdivided into two parts, and the powder unloaded from position F4 forms broken veining V4.
  • a veining distribution sequence with consequent changes in the pattern on the tiles can be obtained by suitably controlling the movement of the distributing valve 41 according to the position of the grid 11A or 11B underneath.
  • the valves can open in variable positions of the grid 11A or 11B at each passage of the trolley 3 under the auxiliary hoppers, with the consequent creation of random patterns.
  • the opening time of each valve, the number of times that the valve opens and the direction of opening (with consequent unloading from either one or the other of the compartments 1A, 31B) can be controlled to increase the number of patterns reproduced on the various tiles.
  • the number of patterns which can be obtained can be additionally increased by using different powders in the four compartments 31A, 31B of the two auxiliary hoppers 31 to manufacture tiles whose veining is distributed in an essentially random fashion.
  • the movement of the distributing valve 41 forces the powder material contained in the volume defined by the aperture 41A or 41B of the valve. Consequently, a very limited opening time of the valve is required to feed the required amount of powder material. This can be exploited to suitably program the distribution of veining V1-V4 in the grid 11A, 11B. Furthermore, the opening and closing system can be exploited to obtain a very accurate control of the starting and end instant of powder feeding from the hoppers 31, with consequent excellent control over the distribution of veining.
  • the auxiliary hopper 31 is definitively closed with a movement of the distributing valve 41 when the loading grids 11A, 11B are passed underneath, essentially before the auxiliary grids 13A, 13B pass to prevent feeding powder material contained in the compartments 31A, 31B into the auxiliary hopper 31. This is because the presence of these powders in the auxiliary grids 13A, 13B is unnecessary.
  • the movement of the trolley ends when the grids 11A, 11B and 13A, 13B are under the main hopper 17 or slightly by the side, as shown in Fig. 5E.
  • the hopper 17 is opened when the grids 11A, 11B, 13A, 13B pass underneath so to feed the powder and fill the grids entirely. Filling is obtained by the movement of the trolley 3 under the hopper 17.
  • each of the grids 11A, 11B contain a mass of basic material from the main hopper 17 and a number of small veins V1-V4 of colored material from the respective auxiliary hopper 31. This veining of material remains essentially in the same position, i.e. next to the baffles 12 of the grids 11A, 11B (as shown in Fig. 6) during the following travel of the trolley 3 towards the press 5, due to the presence of the material fed by the hopper 17 on top.
  • the colored powders fed by the auxiliary hoppers 31 form veining which remains visible on the surface of the tile.
  • the veining can be enhanced by slightly polishing the visible surface of the tile after pressing, either before or after firing.
  • the resulting product in essence, is a ceramic tile comprising a main thickness made of basic material (whose color can be uniform or variable in the tile and from tile to tile) with veining of a different color with respect to that of the basic material on the visible surface of the tile formed by the random distribution of coloring powders, said veining concerning a fraction of the thickness of the tile.
  • An effect of the random distribution of the decoration - also if less valuable - can be obtained by using an auxiliary hopper which is not subdivided into two portions, but feeds a single type of coloring powder.
  • the number of coloring powders which can be used can be increased by using more than one auxiliary hopper arranged in series.
  • two auxiliary hoppers can be arranged in series, each split into two internal compartments and equipped with a distributing valve with two feeding apertures. In this way, four different types of coloring powders can be fed in different ways.
  • the illustrated device can be advantageously controlled by a central programmable control unit, e.g. a programmable logic controller (PLC) or a microprocessor.
  • the control unit manages the movement of the trolley 3, the opening and closing of the main hopper 17 (which is advantageously provided with a lower closing unit 16), the movement of the distributing valves 41, the operation of the distribution units 20A-20C or other means of distribution of the powders to the main hopper 17, and all other required movements.
