Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for continuously forming a product tile, which has a convex or concave surface on its surface, by joining the back sides of the product tile to each other, and then forming a molded body to be divided into two. The present invention relates to a method for manufacturing irregularly shaped tiles, which is extruded and cut into predetermined dimensions.

[Conventional technology and its drawbacks]

Conventionally, for example, No. 7111! The production of the irregularly shaped tile l shown in J, which is intended to be divided into two parts, is carried out by the vertical punching method shown in FIG. That is, a mold 3 is attached to the front side of the extruder 2 to extrude the plastic clay, and convex portions 5.5 are formed on the left and right extrusion side surfaces 4a and 4b.

The extruded molded body 4 is cut into a predetermined size (slightly larger than a plurality of irregularly shaped tiles l in the extrusion direction) by a rough cutter 7 using a piano wire 6, and then extruded by a pusher 8. It is transported in the direction perpendicular to the direction. Then, as in the case of the cutting machine 7 described above, the tile is cut into predetermined dimensions by a cutting machine 9 using piano wire 6.

After that, the molded body 4 is dried, and the extruded side surfaces 4a and 4b are glazed. After firing, the irregularly shaped tile 1 is divided into two product tiles (not shown) from the central dividing portion 4c. Extruded side surfaces 4a and 4b of molded body 4
are the tile surfaces of the product tiles, respectively.

In this way, conventionally, two product tiles are obtained from the irregularly shaped tile l of l (if). It does not have sufficient hardness.Therefore, when @a of the convex surface 5 is 10% or less of the longitudinal dimension A of the molded body 4, when the pusher 8 transfers it in the direction perpendicular to the extrusion direction, the convex surface 5 In such cases, automatic cutting using the pusher 8 is not possible, so a manual cutting machine 10 shown in FIG. This is inefficient because the tiles are cut into predetermined tile dimensions.This is also the case with irregularly shaped tiles 11, 12, and 13 shown in FIGS. 8 to 10.

For this reason, it is necessary to match the manual cutting operation (1iaio), which is slow due to the nature of the operation, and the extrusion molding operation to the slower one depending on the progress of the irregular tile 1.11.
There was a drawback that the production efficiency of 12.13 was significantly reduced.

[Means for solving problems]

The present invention improves and eliminates the above drawbacks of the conventional manufacturing method for irregularly shaped tiles, and enables automatic cutting of irregularly shaped tiles with concave or convex surfaces of any shape, thereby increasing production efficiency. The aim is to maintain it high.

Therefore, the gist of the present invention is to attach a mold to the front of an extruder to turn plastic clay into tangible clay, and to press the back surfaces of product tiles in which a convex or concave surface is formed on the tile surface. In a method for producing irregularly shaped tiles, in which a molded body to be divided into two parts is continuously extruded in a state in which two parts are joined together, and the molded body is cut into a predetermined size, the tangible clay extruded by an extruder is The mold is used to separate the upper cutout, the molded body, and the lower cutout, and immediately after separation, the upper cutout is removed, and a release agent is injected between the molded body and the lower cutout. , the irregularly shaped tiles are transported to a cutting process in a state where they are in close contact with each other to be cut into a predetermined size, and the lower part of the tiles is removed during the subsequent drying process. This is the manufacturing method.

The manufacturing method of the present invention will be explained in more detail below based on embodiments shown in the drawings. Note that the same shuttle numbers as in the conventional case refer to the same members.

〔Example〕

FIG. 1 is a perspective view showing the entire extrusion molding line formed through the manufacturing method of the present invention. In this embodiment, two irregularly shaped tiles 11 shown in FIG. 8 are extruded at the same time in parallel in the horizontal direction. The tangible clay 18 extruded from the mold 15 by the extruder 16 is cut into upper and lower cutouts 17a, 17 by the mold 15, as shown in FIG.
b and the molded body 17. In addition, the left and right molded bodies 1
7.17 and cutout 17a.

17b are also separated at the same time. Then, the upper cut portions 17a, 17a are transferred onto a conveyor 20 that moves in a direction perpendicular to the extrusion direction above and below the table 19, and are discharged. On the other hand, the molded body 17.17 immediately after leaving the mold 15, the cutout part 17b on the lower side,
A slight gap is formed between it and 17b. Therefore, in this embodiment, a mold release agent is injected into the gap from the front side surface of the mold 15 using a spray nozzle (not shown) or the like. This is to facilitate separation of the two in the subsequent process.

The molded bodies 17.17 extruded in this manner move on the table 19 while being placed on the cutouts 17b, 17b on the lower side. Then, as in the conventional case, the rough cutter 7 cuts the tile into a predetermined size (a size slightly longer than a plurality of irregularly shaped tiles 1 in the extrusion direction). When the molded body 17.17 and the cutout portions 17a and 17b on the lower side are pushed out to the position of the table 21, they are transferred by the pusher 8 to the position of the table 23 through the table 22 in a direction perpendicular to the extrusion direction.

Here, the pusher 8 includes one side surface 17d of the molded body 17 and one side surface 1 of the lower cutout portion 17b.
7e and promote these simultaneously. Furthermore, the back and front surfaces of the lower cutout portions 17b, 17b are joined to the table 21. Therefore, stable transfer is possible. That is, even if the thickness of the side surface 17d of the molded body 17 is extremely small, the lower side cutout 1
By increasing the thickness of 7b, stable transfer is possible.

A cutting machine 9 is disposed between the table 22 and the table 23, and the cutting machine 9 has a plurality of piano wires 6 stretched in the vertical direction at predetermined intervals. The molded body 17.17 and the cutout portions 17b, 17b on the lower side are cut to a predetermined tile width dimension.

FIG. 1 shows the case where it is cut into five pieces. FIG. 3 also shows the molded body 17°17 after cutting and the cutout part 17b on the lower side.
, 17b.

Thereafter, the molded bodies 17 are taken out one by one, transferred onto a drying plate 24 as shown in FIG. 4, and transported to a drying process. At the time of taking out, a mold release agent is injected between the molded bodies 17, 17 and the cut-out portions 17b, 17b on the lower side, so that separation of the two is extremely easy. After drying, glaze is applied to the convex surfaces 17c and 17c of the molded body 17,
Fire in a roller hearth kiln, etc.

Thereby, it is possible to manufacture irregularly shaped tiles 11 shown in FIG.

It should be noted that, as in the conventional case, the irregularly shaped tile 11 is divided into two from the central dividing portion 11b, and the convex surfaces 11a and lla become the tile surface of the divided product tile.

In this way, in this embodiment, two irregularly shaped tiles 11
．． 11 can be extrusion-molded at the same time, and automatic cutting is possible since the molded bodies 17 and 17 are placed on the lower side cut-out parts 17b and are transferred in a direction perpendicular to the extrusion direction. . Therefore, the productivity of irregularly shaped tiles 11 can be improved.

Incidentally, the method of the present invention is not limited to the above-described embodiments, and can be modified as appropriate.

For example, the irregularly shaped tiles may have the shapes shown in FIGS. 9 and 10, or may have other shapes. In addition, there is a rough cutting machine 7. The pusher 8 and the cutting machine 9 may be other than these.

Furthermore, within the capacity of the extruder 16, it is possible to simultaneously extrude three or more irregularly shaped tiles in parallel. Therefore, it is clear that the present invention does not require that a plurality of irregularly shaped tiles be extruded simultaneously in parallel.

(Effects of the Invention) As explained above, in the present invention, in the case of irregularly shaped tiles in which the surface of the product tile is formed to be a convex or concave surface, the convex or concave surface, etc. Even if the shape is different, it can be automatically cut using a pusher and a cutting machine, which significantly improves productivity.Furthermore, stable extrusion is possible without crushing or deforming the convex or concave surfaces.
