State of the art

The elaboration of mosaics in natural stone is dates back to very old dates (stone mosaics are preserved natural from the time of the Roman Empire in many ruins). I weighed to the great tradition that this product presents, its manufacture does not has experienced great progress and requires a high amount of labor (the pieces of stone that make up the mosaic or tiles are glued by hand one by one), which causes it to be a slow and expensive process.

For the reasons mentioned, so far the The use of natural stone mosaics has been restricted to very specific applications

The present invention is embedded in the elaboration of this type of products, but allowing a simple manufacturing and that can also be easily industrialized in order to allow high production of this type of products.

Explanation and description of the drawings

The invention that is intended to be patented by This request is the creation of a manufacturing process for stone mosaics, which can allow high production and some manufacturing costs much lower than those obtained in the traditional processes, since it is capable of being totally automated

When treating the invention of a process of mosaic fabrication, it has been deemed appropriate to join the points explanation and description of the drawings.

The manufacturing process begins with gluing of natural stone tiles. The tile format and the material (by material we understand the type of stone used, by example white marble, red travertine, gray granite, etc.) choose according to the desired final product (tile size, table size, color scheme, etc.).

Figure 1 shows how this is done First glue Proceeding according to the scheme in Figure 1, we would get a block formed by n tiles. The number n of tiles will depend on the final table that you want to obtain.

Figure 2 shows how the block would be obtained from the gluing of the stone pieces.

From the laboratory tests and the information collected, we have verified that the adhesive used for bonding the tiles can be of the epoxy resin or polyurethane resin type.
no.

The following process consists of sawing the block of figure 2, following the arrangement indicated in the Figure 3. For the sawing process, you can use the cutting tools commonly used in the sector Industrial natural stone.

As can be seen in Figure 3, it they would get a series of stone tables of dimensions (n \ cdota) \ cdotd \ cdotb. The number of tables, m, will not be the number obtained by dividing c by d, since the tools of cut wasted material (there is a decrease in the performance).

Once the tables are obtained, it is carried back another bonding process, as represented in the Figure 4. As indicated above, for bonding We can use an epoxy or polyurethane type adhesive.

Once the process in Figure 4 is finished, we would obtain a block like the one represented in figure 5. Finally, the block would be cut as outlined in the figure 6.

The final product of this process would be the dimension tables (m \ cdotd) \ cdot (n \ cdota) \ cdote. These mosaic tables can be treated in the current processes of tamping, polishing or cutting that are carried out in the industries of stone.

Embodiment

This section will show an example of production of these natural stone mosaics, which is not intended be limited to the scope of the technique object of this request for patent.

The dimensions that you want to obtain from Final product (mosaic tables) are 120 x 100 x 2 cm. further the tiles will have surface dimensions of 2 x 2 cm.

The first step of the process will be the paste of 50 stone tiles of dimensions 60 x 30 x 2 cm. This process is Repeat two more times, so you will finally get 3 blocks of dimensions 100 x 60 x 30 cm. This process is schematized in figures 1 and 2, where parameters a, b, c and n They have the following values:

\ text {*}

a = 2 cm.

\ text {*}

b = 30 cm

\ text {*}

c = 60 cm

\ text {*}

n = 50 units

Then these blocks will be cut following the direction shown in figure 3. In each cut wastes 1 cm. of material, so that each block is generated 20 boards of 100 x 30 x 2 cm. (the parameter d of the figure, in the Explained embodiment would be equal to 2 cm.)

The 60 tables produced from the first cutting stage are glued following the arrangement shown in figure 4. Acting in the manner described, a block of 120 x 100 x 30 cm is obtained. Finally, this block is cut again as shown in Figure 6 and we get 10 boards of 120 x 20 x 2 cm. (In each cut 1 cm of material is wasted and the parameter e of Figure 6 is equal in this embodiment to 2 cm.).

Tables manufactured following this process, are can use for many applications, such as countertops, flooring, facades, tables, etc.

Another alternative that allows this product is its use for crafts if the second stage of cut (figure 6).

Claims (4)

1. New manufacturing procedure for Easily automatable natural stone mosaics, which part of boards or tiles of natural stone, of varying dimensions that we will generically name a, b and c (thickness, width and length), which comprises the following stages: I. Application of a suitable adhesive (for example an epoxy resin or a polyurethane resin) on the surface of the tables defined by the addresses of b and c. The application it can be done on only one of the faces or on both, in function of the characteristics of the adhesive. II. Stacking and pasting the boards, at along the direction of a, so that it is obtained at the end of this stage a block composed of n tables of dimensions n \ cdota, b and c. III. Block cut obtained in stage II parallel to the plane defined by the directions of \ ndota and b in new tables with a imposed thickness defined as d. Be they will obtain new tables at the end of the stage composed of pasted bands of the raw material of dimensions n \ cdota, b and d. IV. Application of adhesive on the boards obtained in stage III, equivalent to stage I. Stacking of said tables in an equivalent way to stage II a along the direction of d, so that you finally get a new block consisting of m tables of dimensions n \ cdota, b y m \ cdotd. V. Cut of the block obtained in stage IV parallel to the plane defined by the directions of \ ndota and m \ cdotd in new tables according to a imposed thickness defined as and. In this way final dimensions mosaic tables are obtained n \ cdota, m \ cdotb and e composed of small squares. According to the defined procedure, the dimensions of the initial tables or tiles (a, b and c), the number of tables to paste to form the first and second of the blocks (n and m), and the thickness imposed for the first and second cut (d and e) is will select according to the desired dimensions for the final product, as well as those of the small squares that constitute the mosaic. 2. A method according to claim 1 characterized in that in the stage IV new tables of unprocessed natural stone are alternated to those resulting from stage III, so that after stage IV, final tables are obtained which alternate small squares with bands. 3. A method according to claims 1 and 2 that includes as raw material any type of material (glass, wood, artificial or agglomerated stone, etc.) that can presented in the form of tables of dimensions a, b and c. 4. A product manufacturing procedure of handicrafts (sinks, fireplaces, moldings, etc.) from the blocks made according to steps I to IV included in the claim 1 or its modifications in claims 2 and 3.
