Description

Procedure, loading device and press for the manufacture of tiles with striated or veined in the mass.

The present invention relates to a procedure for the manufacture of tiles with striated or veined in the dough and to a press and loading device that use this process. In the manufacture of tiles, the problem is known to get a striatum in the dough.

In the prior art several are known devices for depositing diversified layers of material to press inside the mold to try to simulate the shape and striatum distribution found, for example, in stone natural. In the document DE-B-1183001 and, as regards the decorated tiles, in the document EP-A-0839618 are released Presses with translational powder loading devices.

It has also been proposed to obtain a box of mold filling with overdraft movement so that you could fill in the vertical position and then take the horizontal position for conventional pouring use in mold. Filling can take place through successive layers of differently colored materials. For better distribution of the striatum it has also been proposed to place distribution channels between the loading hoppers and the tilting box.

In a different embodiment, it has been proposed to directly fill a vertical mold that, to then it would be pressed laterally with a shaft press horizontal.

The prior art devices do not they provide completely satisfactory results, especially in relation to the impression of naturalness of the striatum.

The general objective of the present invention is remedy the aforementioned problems by providing a procedure, a press and a loading device that allow the obtaining tiles with veining or striated in the mass that are of very natural and obvious appearance on both main sides of the tile.

With this objective it is provided, according to the present invention, a tile press according to claim one.

A procedure is also provided for manufacture of tiles with marbling in the mass according to the claim 6.

To clarify the explanation of the principles Innovators of the present invention and their advantages in comparison with the prior art described below, with the help of the attached drawings, a possible embodiment by way of non-limiting example in which these principles apply. In the drawings:

Figure 1 illustrates a front elevation view schematic vertical of a press with loading device according to the present invention;

Figure 2 illustrates a front view of the device depicted in Figure 1; Y

Figure 3 illustrates a sectional side view cross and schematic of a detail of the device of the Figure one.

With reference to the Figures, a press of tiles indicated in full by reference number 10 comprises a pressing mold 11 disposed between the plates presses 12, 13 and in which a loading device with a box 14 pour the powder to be pressed. The charging device 14 it comprises a main hopper 15 in which the powder is fed to produce the mass of the tile and at least one secondary hopper 16 in which powder is fed for the production of the striatum or veined in the dough.

The main and secondary hoppers receive the respective powders from the feeder units and ducts 23, 24.

The main hopper 15 and the secondary hopper 16 they pour under control, for example, by means of pouring gates machined 25, 26 in a channel 17 to send the powder to the box load 18 that moves between a resting position shown with solid lines in Figure 1, outside the plates of the press and a position represented in dashed lines for pouring in the mold. The movement of the mounted box, for example, in a motorized carriage and the pouring of dust inside the mold is get with known devices and procedures easily imaginable by experts in this field and therefore, it is not described in more detail or represented in the figures.

According to the principles of the present invention, an accumulation well is arranged between the channel and the box intermediate 19 that extends vertically and receives in the part top the dust poured from the canal and in turn, pour it, under control, from the bottom to the inside of the arranged box under it while moving box 18 from its resting position to its position for pouring into the mold. Preferably, the box 18 has dividing walls vertical 31.

The accumulation well 19 has a shape generally parallelepipedic with dimension A in the direction of movement of the box, which is practically almost the internal height of the box and a transverse width B which is almost the width internal transverse of the box.

As can also be seen in Figure 3, for the spill sent, the accumulation well 19 has a mouth of lower discharge 20 closed by a discharge gate 21 which is extends over the entire transverse width of the well and is driven by means of an actuator 22.

As clearly illustrated in Figure 2, the main hopper 15 and secondary hopper 16 move transversely along channel 17 by means of a car motorized 27 that travels on tracks 28 to distribute the Pouring of the respective powders into the channel.

Again as can be seen in Figure 2, The loading device can be multiple to serve molds presses with multiple prints.

Figure 2 illustrates, for example, three units of load 14a, 14b, 14c that are almost identical.

As can be seen in Figure 3, the load of dust takes place by loading in the vertical well 19 the dust 29 to be pressed to form the mass of the tile and the powder 30 to form the grain in the dough. The distribution takes place in different amounts and at different intervals, depending on the concrete aesthetic effect that you want to achieve. Once the well, gate 21 opens to pour the dust along the horizontal box 18 which, at the same time, moves under the well to move to the pouring position in the mold. In this way, the box is filled with the default striatum distribution in the vertical well during loading.

It is clear that the ends have been achieved default It has been discovered that the load made according to procedure and the device described above get aesthetic results qualitatively much better than those They can get in the prior art. In particular, the striatum obtained in the dough and evident on both sides of the tile has A much more natural and aesthetically pleasing appearance.

Of course, the previous description of a embodiment, applying the innovative principles of the present invention, is provided by way of non-limiting example of these principles within the scope of the exclusive right claimed herein. For example, although will prefer the movement of the box under intermediate well 19 to optimize cycle time, for charging purposes according to the present invention the reciprocal movement must be understood As a relative movement. Therefore, the well can be provided so that it will move to move above the box.
