Description
- The invention refers to an apparatus intended to perform the pressing and water suction steps during the manufacturing process of tiles, namely single-layer tiles and to a method for pressing single-layer tiles.
- For the same purpose, there are known apparatus of the type disclosed for example in the international patent application
WO-A-2012/160583 and inEP-A-1 262 296 , said units envisaging a frame comprising a mold in which it is possible to introduce a water-based mixture and, during operation, is pressed by a plate which is movable relative to the frame and equipped with suction ducts distributed next to the lower pressing surface, where at least one filter applied to the lower face of the plate is also envisaged. - In the systems of a known type, a suction source is envisaged and it is intended simultaneously to sucks centrally the water through the filter below the pressing plate, and the water and the unfiltered sediment that settle in the perimeter movement gap between the frame and the plate.
- The known solutions, however, have some drawbacks due to the simultaneous performance of the central and peripheral suction steps.
- It has been verified that during the molding step, the presence of perimetral suction open holes involves a considerable reduction of the applied pressure and therefore the suction capacity. This vacuum reduction indicates an increase in the time needed to suck the exceeding water out of the mixture until the desired ratio water/mixture is reached. Another, not negligible, disadvantage of the suction steps simultaneity can be observed on to the pressed tile and it is due to the fact that the suction through the lateral holes excessively dries the upper perimeter of the tile and this causing, at the end of the process, this part to be the most friable area of the tile, since concrete suffered from lack of moisture in this area during the hardening phase.
- However, turning down the perimetral suction would result in a presence of exceeding water in the perimetral area, and therefore part of this water would pour back on the tile and on the mold during the releasing step of the tile from the mold. These are both negative effects. In the first case, the freshly molded tile shows still fresh concrete and water pouring on the tile tends to locally soften it; in the second case, the quantity of water pouring back on the ring nut tends to pool there and increases the possibility of dirt accumulating and thus causing - over time - difficulties to close the mold over the bed.
- It is therefore needed a piece of equipment able to solve the drawbacks of the known systems, thus obtaining - at the same time - a better efficiency of the pressing system during the pressing step of the tile.
- These objects have been achieved by developing a device and a method according to
independent claims 1 and 6 respectively. - A first advantage is that the flow rate of the vacuum pump is used to the maximum of its possibilities during the first suction step and with relatively low pressing values, whereas only during the final pressing step, suction is activated in the perimeter movement gap between plate and mold.
- A further advantage is that the upper perimeter of the tile is not excessively dried.
- These and other advantages will be better understood by anyone skilled in the art from the following description and the accompanying drawings, given as a non-limiting example, wherein:

Figure 10 shows the detail "C" of the angular suction area of the plate shown infigure 9 ; - With reference to the accompanying drawings, it is disclosed a preferred embodiment of a unit 1 according to the invention intended for presses of the type used for manufacturing single-layer tiles starting from an underlying water-based
mixture 2 contained into apressing mold 3. - The unit 1, starting from the contact area with the
mixture 2, substantially comprises:
Apressing unit 110 movable with respect to themold 3 and afilter 6 applied to the pressing unit next to apressing surface 25. - In the shown non-limiting example, the pressing unit comprises in greater detail:
- a
perimeter frame 5, - a
filter 6 hold by the frame and in contact with the mixture so as to allow the suction of the liquid phase from the top, - a first
lower manifold 7 which is preferably a metal mesh or a pack of overlappingmetal meshes 78, - a
second manifold 8 which is preferably a perforated plate in contact with the upper face of thefirst manifold 7, - a
suction plate 9, which is preferably mounted by means ofmagnets 10 on a vertically movablepressing pad 11. - The mounting of the
manifolds plate 9 is achieved by using screws 46A into theholes 22 of theplate 9, in such a way that the manifolds remain adherent to theplate 9 when only the filter needs replacing or they can also be removed occasionally when they need to be disassembled for a more thorough cleaning. - Preferably, the
second manifold 8 is obtained by a thin stainless steel sheet, having a fully perforated surface. - Alternatively, and with reference to
figure 6b , thecollectors sub-filter structure 78 created by the superposition of three or more, preferably four,mesh manifolds 7 suitably mounted in a pack and staggered by half a pitch so that they fit above one another, thus obtaining a substantially flat and compact structure. - With this solution,
structure 78 directly channels water to the variousdiagonal ducts 32,perimetral ducts 35 and to the fouropenings 34 of the corners. - In particular (
figure 10 ), twodiagonal ducts 32 located on the right and on the left with respect to the geometric diagonals "d" of the plate can be extended withsections 37 beyond theopening 34 towards the corners of the mold. - The direct passage of water takes place, therefore, from the
filter 6 to the overlappingmesh sub-filter 78 and to the various steps 32-34-35 for their usable surface and no longer through the more or less thick holes of theplate 8. Advantageously, the draining function of theplate 9 is facilitated over the entire molding or pressingsurface 25. In addition, the overlapping of the four above-described meshes creates a structure capable of withstanding without flexing in those wide water passage areas, next to thechannels plate 9 was processed by using acentring slot 43 to house the twomanifolds pressing surface 25 which is substantially flat and devoid of roughness or discontinuities, which will contact theliquid mixture 2 during the pressing procedure. During thenecessary processing 43 to house the two manifolds, and more precisely on the surface where thesecond manifold 8 lies, a number of intersectingdiagonal ducts 32 have been created, theholes 33 on thesecond manifold 8 are also diagonally positioned, so as to let the water/air flow pass directly from the holes to the ducts. - On the
upper surface 24 ofplate 9 there are: - at the ends of the diagonals, four
housings 27 having a generally oval shape surrounded by O-ring gaskets. In thehousings 27 vacuum comes from the fourholes 28 positioned on thepressing pad 11; - a
channel 29 to house an O-ring gasket protecting themagnetic element 10 housed on thepad 11; - supply
air ducts 31 with O-ring to pneumatically extract the frame, when the latter is mounted together with the buffer. Said ducts orholes 31 are also useful if the frame needs to be removed manually from the plate when it is detached from the buffer; -
holes 47 to apply the locking and removal brackets of the plate when it lies on the bottom of the mold; -
holes 46 to refer to the centring pins between the buffer and the plaque. - The connection for the air/water passage between the upper and lower sides of the
plate 9 is realized next to theupper housings 27. In these four areas, throughopenings 34 generally having an L shape, have been created and connect the bottom surface and the top surface of the plate, into which theducts 32 of the bottom surface of the plate (e.g. four), centered on the diagonals, directly flow. The extension of allother ducts 32 is delimited by fourperimetral ducts 35. Preferably, theperimetral ducts 35 are deeper than thediagonal ducts 32 and flow into the L-shaped openings 34. - In
figures 4, 5 the detail of the ducts flowing into thelateral sides 106 of the plate used for the suction of water and of the unfiltered sediment found in theinterspace 72 between theplate 9 and themold 3. - In particular, with reference to
figure 4 , thebuffer 11 is shown and equipped withfirst holes cavities 27 to allow the vacuum to get to the corners of the plate from where the filtered water is sucked, andadditional holes elastomer perimetral cavities 102 to send vacuum to the chambers into which the water and the sediment, pooled in the perimeter gap between theplate 9 and the mold during the pressing-squeezing step, flow. - In a preferred embodiment, shown in
figure 8a , theelastomer chamber 102 has an upper part having a semi-toroidal shape on both sides A and operating with respect to the buffer as a seal shaped as a loop. The bag B of thechamber 102 forms a pooling area for the water and the sediment flowing into its end holes D through the holes of the plate 36A. - The housing B guarantees the closing between plaque and buffer, even when the sediment is stuck to the buffer surface in the area between the two toroidal parts A. The entire perimeter profile of the
chamber 102 has also preferably a diverging inclination C having an angle of approximately seven degrees with respect to the surface of theplate 9, in such a way that after inserting it into the plate, it is locked into place. - According to the invention, and with particular reference to
figure 7 , the suction system of the equipment comprises a pneumatic unit having a manifold 103 equipped with acoupling device 107, which receives the vacuum generated by the vacuum pump. - The manifold 103 has four outlets B1-B2-B3-B4, which are connected to four
coupling points 23 of the buffer respectively, and which lead the vacuum in the pressing surface for sucking out the through filtered water throughfilter 6. In the end part of the manifold 103, it can be found avalve 104, which is normally shut, for example a valve equipped with a pneumatically actuatedplate 109, which, if activated by means of a suitablepneumatic control 108, allows the communication of thevacuum 107 with the ducts A1, A2 , A3, A4 connected to the fourconnections 100 of the buffer that are, in turn, in communication through theseals 102 and theperimetral holes 36a to the side edges of theplate 9 for the suction of water and unfiltered sediment. - During its use, the
mixture 2 is measured out and poured into themold 3, such molds have a cylindrical shape and the mixture is poured from a height. In order to level out the poured mixture in the mold, what needs to be done is having the mold vibrate, according to a well-known technique. After pouring the mixture into the mold, the pressing buffer is lowered so thatplate 9 comes into contact with the mixture and perform the suction and squeezing steps aimed at obtaining the correct water stoichiometric ratio and the desired compactness. - For example, in a preferred embodiment of the suction and pressing steps, the applied pressure will vary proportionally and progressively, and will have a lower pressure on the mixture in its initial step and a higher pressure during the final compaction step.
- With the adopted solution, during the pressing and squeezing steps of the mixture, the operator may decide to trigger the vacuum in the manifold 103, and consequently under the
filter 6, before the filter comes into contact with themixture 2, or at the beginning of the squeezing step, by keeping the vacuum until the end of the pressing process. - According to the invention, the
valve 104 is controlled upon opening 1-2 seconds before the end time of the pressing process, since the exceeding water in the mixture is sucked out when the specific molding pressure is low and thus the light specific pressure together with the high pneumatic vacuum facilitate the ascent of the water from the entire mixture and get to filter 6 and to the lower manifolds of the plate. - Advantageously, since during this step no pressure drop is registered because of the opening of the lateral holes 36A of the plate, the vacuum pump is exploited to the maximum and only for this function.
- In the final phase of the pressing process, for example from 75 to 100% of the final set specific pressure, the compaction of the various components of the mixture is almost exclusively due to the strong specific molding pressure. For this reason, it is possible and advantageous to use only at this stage, even for a few seconds, part of the vacuum and the of flow rate of the pump via the
valve 104 to trigger also the water and the sediment suction in the interspace between the plate and the mold via theholes 100. - In a possible preferred embodiment, the suction system is provided with two pumps with different functional characteristics that can be selectively associated to the central suction phase or to the side suction phase, for example a liquid ring pump for extracting water from the filter and a side blower pump for the side suction of water and sediment.
- The present invention has been disclosed according to preferred embodiments, but equivalent variants can be designed without departing from the scope of the invention.
