Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for firing a roof tile.

[0002]

2. Description of the Related Art Roof tiles come in various shapes such as flat tiles and flue tiles, and several types of roof tiles are used depending on the place of use. Molded, glaze, and dried roof tile elements are loaded on a shelf board brick, which is placed on a baking carriage and baked in a tunnel kiln. The tunnel kiln is provided with a pre-tropical zone, a firing zone, and a cooling zone, a number of trucks are sent one after another, and a number of roof tiles are fired continuously.

The flat tile, which is the most used among various roof tiles, has a shape that can be stood without a support material.
Therefore, the bricks are fired by stacking them on the shelf bricks at equal intervals. On the other hand, the roof tiles used for buildings
It is a shape that cannot be self-sustaining like a flat roof tile. For this reason, conventionally, the roof tiles are fired using shelf bricks provided with support pins at equal intervals. That is, the roof tiles are inserted between two or two sets of support pins provided on the shelf bricks, and the support pins are supported and stacked so that the roof tiles do not fall. It should be noted that the shelf bricks are usually provided with two grooves and a round bar made of heat-resistant steel is arranged in the grooves. Then, stack the Reito tile on the round bar and fire it with the shelf board floating a little.

[0004]

In the conventional firing process of flat roof tiles, loading and unloading work of the tile base material onto the bogie has been automated by the loading and unloading device. However, in the firing process of Reto tile, many support pins are obstacles, and the loading and unloading work cannot be automated, so that the work is dependent on manual work.

[0005] The manual loading and unloading work of the roof tiles is a work of inserting and removing the roof tiles one by one between the narrow support pins, and this is performed on the carriage. For this reason, the work becomes complicated, and the glaze surface is scratched, the support pin is damaged, and the flue tile and the support pin are easily adhered by the glaze when unloading. Furthermore, the work place is hot due to the residual heat of the trolley, and the cramped work environment near the trolley is harsh and dangerous, and automation is also strongly desired for loading and unloading the stile tiles.

The present invention solves the problems of the prior art as described above and mechanizes the loading and unloading operations.
It is an object of the present invention to provide a firing method for flue tiles that can be automated to save labor and improve the danger of work and the work environment.

[0007]

According to the present invention, three heat-resistant steel supporting members 13 for supporting a roof tile 16 are arranged side by side on a shelf board brick 11, and the supporting portion of the central supporting member 13 is different from the other supporting members. It should be 1.5 to 2.5 mm higher than the supporting portion of the supporting member 13, and 5 to 5 mm on at least one end surface of the roof tile 16
A state in which a recess 17 having an inclination of 8 degrees is provided, the recess 17 is supported by the support portion of the central support member 13, and the reed tile 16 is inclined at an angle of 3 to 5 degrees with respect to the vertical line. The gist is the method of firing Reto tiles, which is characterized by firing in a self-supporting manner.

[0008]

[Function] Since the reed tiles are self-supporting and fired without using the support pins, the loading and unloading work can be automated.

The supporting surface of the central supporting member is set to be 1.5 to 2.5 mm higher than the other supporting surfaces, the inclination angle of the concave portion of the end face of the reed tile is set to 5 to 8 degrees, and the reed tile is shelved. By leaning 3 to 5 degrees with respect to the vertical line when it is loaded on the board brick, it is possible to make the sword tile stand in the most stable state. For this reason, the sword of the dolly does not fall over due to the shaking of a normal trolley.

If the above three values are not within the above range, the sword tile cannot be stably supported by itself. That is,
By the synergistic action of the three conditions, it is possible to achieve self-sustaining in an optimal state.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a state in which the roof tile 16 is set on the carriage 10. FIG. 2 is a perspective view showing a state where the roof tile 16 is stacked on the shelf brick 11.

The carriage 10 has wheels 9 and is configured to be able to travel on rails 8 laid in a tunnel kiln (not shown). A plurality of legs 12 are provided on the dolly 10, and a shelf brick 11 is placed on the legs 12. 4 shelves 11 can be installed on this trolley 10, but if a larger trolley 10 is used, more shelves 1 can be installed.
1 can be installed.

The shelf bricks are made of a high alumina material and have dimensions of 440 × 220 × 40 mm, for example. Three grooves 20 are provided on the front and back surfaces of the shelf brick 11 along the longitudinal direction. The groove 20 on the back surface is provided so that the back surface can also be used when the surface is contaminated with glaze or the like and cannot be used. The central groove is slightly offset to the side of one groove, for example, 15 mm from the center line. The distance between the left and right grooves is 190 mm, for example
And The central groove is set to be slightly shallower than the left and right grooves, for example, 1.5 mm. Therefore, when a supporting member such as a heat-resistant steel round bar 13 is set in the groove 20,
The supporting part of the central round bar 13 is 1.5 mm more than the left and right round bars.
Only higher. The support portion is a portion that actually supports the roof tile, and in the case of a round bar, corresponds to the vicinity of the uppermost portion. Round bar 13
For example, those having a diameter of 10 mm and a length of 400 mm are used.

Generally, the roof tile 16 is manufactured in a shape as shown in FIG. 2, and is divided into two parts from a center line 19 by a hammer at a construction site. Further, the concave portion 18 is used as a hook during use.

As shown enlarged in FIG. 3, recesses 17 are provided in the upper and lower end surfaces of the roof tile 16. Recess 1
7 is formed in the center of the end face with a predetermined width. Recess 17
Is inclined toward the inner side of the curved surface of the roof tile 16 and its gradient is set to, for example, 1/10.

When stacking the roof tile 16 on the shelf board 11,
Both side portions of the lower end surface of the stile tile are supported by the left and right round bars 13, and the recess 17 is supported by the central round bar 13. Then, the roof tile 16 inclines slightly in the direction of the curved inner surface, for example, inclines by 4 degrees with respect to the vertical line, and stands on its own.

Two tilt-prevention pins 21 made of ceramic are fixed to both ends of the shelf brick 11. Due to the action of the fall-prevention pin 21, even if an impact force is exerted on the bogie for some reason, the reed tile 16 does not fall into shogi. However, in the case of a normal bogie shake, the fall prevention pin 2
1 is not necessary.

A loading experiment shown in FIG. 2 was adopted, and a dolly larger than the dolly shown in FIG. 11 shelves bricks are loaded with 11 red tiles,
A total of 15 shelf bricks were installed on the trolley. Shelf board bricks were arranged in 3 rows and 5 columns. The total number of 熨 堂 tiles loaded is 1
It was 65 sheets.

On the other hand, as a conventional example, firing was carried out by stacking red tiles on a shelf brick provided with a large number of support pins. The size of the shelf bricks is the same as that of the embodiment, but since a large number of support pins are provided, only eight roof tiles can be loaded on one shelf plate. This shelf board brick was provided with two grooves, and two heat-resistant steel round bars were set therein. Further, since the support pin is provided, the fall prevention pin is not provided.

Firing was performed under the same conditions as in the experimental example and the conventional example described above. In the conventional example, it is impossible to automatically load and unload the red roof tiles, which requires 6 workers. In the experiment example, automation was possible and only one work supervisor could perform the firing work.

[0022]

According to the present invention, three heat-resistant steel supporting members 13 for supporting the roof tile 16 are arranged and installed on the shelf board brick 11, and the supporting portion of the central supporting member 13 is another supporting member 1.
3 to 1.5 to 2.5 mm higher than the support part,
A recess 17 having an inclination of 5 to 8 degrees is provided on at least one end surface of the reed tile 16 so that the recess 17 can be supported by the support portion of the central support member 13, and the reed tile 16 can be supported with respect to the vertical line. The main feature of this method is the firing method for Reito tiles, which is characterized by inclining it at an angle of 3 to 5 degrees, and firing it independently. Work can be automated. In the past, six workers were required for loading and unloading work, but automation allows only one supervisor to perform firing, which saves labor. In addition, since the Reito tile is self-sustaining with the optimum balance, there is no possibility that the Reit tile will fall down due to the shaking of the normal carriage. Moreover, since a large number of support pins are not required on the shelf bricks, the loading efficiency is about 30.
You can raise%.

The present invention is not limited to the above embodiment. For example, the shape and thickness of the shelf bricks can be variously modified. Further, the support member may be a square bar having a polygonal cross section or a bar having a semicircular cross section, instead of the round bar, in which case the groove of the shelf board brick can be omitted. You may provide four or more support members. Furthermore, the shape of the Rei roof tile can be modified in various ways. The recess may be provided only on one end surface. It is also possible to provide recesses on both ends of the end face or on the entire end face.
