Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention allows a tile placed on a moving table to freely reciprocate between a plurality of glaze stations to form a desired glaze layer having a multilayer structure. The present invention relates to a glazed method for forming.

[Prior Art] Usually, in a glazing line for tiles or the like, a tile is conveyed from one side of a conveying device such as a V-belt or a flat belt to the other side, and at a glazing station arranged on the way, The glaze is applied to the surface of the tile base by spraying or curtaining. That is, the conventional glazed line is
It is glazed with a one-way system.

[Problems to be Solved by the Invention]

However, in the above-mentioned glazed line, if the glaze layer is to have a multi-layered structure, it is necessary to add the glazed stations continuously in a straight line, and there is a drawback that the total length of the glazed line becomes extremely long. In the case of a V-belt or flat-belt conveyor system, when a large tile of 300 mm square or more is conveyed, the belt repeatedly swings up and down due to the weight of the tile itself, and its moving speed changes partially discontinuously. Then, there is a drawback that a so-called crisping phenomenon occurs and the amount of glaze applied to the surface of the tile base material varies. If there is such a variation in the coating amount, a smooth tile surface cannot be obtained, and a uniform pattern cannot be obtained. Therefore, there is a drawback that the product value of the tile is reduced.

[Means for Solving the Problems]

The present invention has been made by improving and removing the above in view of the above-mentioned conventional problems, and provides a glaze method in which a plurality of glaze stations can be freely reciprocated to obtain a glaze layer. It is a thing.

Thus, the means adopted by the present invention in order to solve the above-mentioned problem is to dispose a movable table capable of reciprocating the glazed line, and to provide a plurality of glazed stations at several points along the glazed line, By arbitrarily moving the moving table back and forth between the glaze stations, a desired multi-layered glaze layer is formed on the surface of the tile placed on the moving table by coating.

[Action]

The moving table can freely reciprocate between a plurality of glazing stations. Therefore, it is easy to make the glaze layer into a multi-layered structure by arbitrarily selecting each glaze station and reciprocating the moving table between them, and to significantly shorten the total length of the glaze line in that case. Is possible.

〔Example〕

The method of the present invention will be described below with reference to the embodiments shown in the drawings.

FIG. 1 is a plan view showing the overall arrangement of a tile manufacturing line to which the method of the present invention is applied. As shown in the figure, in this tile manufacturing line, a roller hearth kiln 2 is arranged on an extension line of the press molding machine 1, and a conveyor device 3 and a glazed line 4 are continuous in parallel with the roller hearth kiln 2. Are arranged. A traverser 5 is arranged between the press molding machine 1 and the roller hearth kiln 2 and one end of the conveying device 3.

The operation of the entire production line is that the tile 6 formed by the press forming machine 1 is first carried into the conveying device 3 by the traverser 5. The loaded tiles 6 are transported to the other end side of the transport device 3 and transferred onto the moving table 7 of the glaze line 4. Then, the glaze stations A, B, and C are arbitrarily moved back and forth to form a desired multi-layered glaze layer on the surface of the tile base. When the glazing is completed, the tiles 6 are supplied from the moving table 7 to the transport device 3, and are supplied to the entrance side of the roller hearth kiln 2 by the traverser 5.
After that, by passing through the roller hearth kiln 2, predetermined firing is performed, and a tile as a product having a multilayer glaze layer is obtained.

As described above, in the present embodiment, in the glazing line 4, the plurality of glazing stations A, B, C are appropriately selected and the moving table 7 is arbitrarily reciprocated to make a glaze layer having a multilayer structure. To form. As shown in FIG. 2, the moving table 7 includes rollers 10, 10 on upper and lower guide rails 9, 9 fixedly installed on a side surface of a pedestal 8 continuously provided over substantially the entire length of the glazed line 4. It is slidably attached via. The pinion 12 of the motor 11 attached to the moving table 7 is meshed with the rack 13 fixedly installed on the upper end surface side of the gantry 8. Therefore, by driving the motor 11, the pinion 12 is rotationally moved on the rack 13, and the moving table 7 can be moved along the upper and lower guide rails 9, 9. The moving table 7 has an arm 14 for mounting the tile 6 on the upper surface thereof as a framework.

By the way, the glazing station A installed in the middle of the glazing line 4 is provided with a glazed booth 15 as shown in FIGS. 3 and 4. Inside the glaze booth 15, a spray device 16 for ejecting glaze or water is installed. Further, the glazing stations B and C are provided with curtain hanging devices 17, 17 shown in FIGS. 5 to 7. This curtain hanging device
Each of 17, 17 has a container 19 having a slit 18 formed on the lower surface side thereof, and a pan 20 for collecting the glaze flowing in a curtain shape from the slit 18 at a predetermined interval below the container 19.
Is installed. Thus, the container 19 and the bread 20 are
It is attached to a rotatable post 21. Motor 22
Is driven, the post 21 is rotated via the pinion 23 and the gear 24. The moving table 7 has a container 19 and a pan 20 when the container 19 and the pan 20 of the curtain hanging device 17, 17 are glazed as shown in FIG.
It is designed to pass between.

Thus, in the glazed line 4 configured in this way,
The glazed procedure of the tile 6 placed on the arm 14 of the moving table 7 via the setter (bed) will be described. First, the motor 11 on the moving table 7 is driven to rotate the pinion 12 to move the moving table 7 into the glazed booth 15 of the glazing station A and stop it. Then, in this state, water is applied to the surface of the tile 6 by the spray device 16,
The water content of the tile 6 is adjusted. This is to make the moisture evenly permeate the entire tile 6 when the glaze is applied, and to eliminate the unevenness of drying of the glaze.

After that, the motor is driven again, the moving table 7 is moved to the glazing station B side, and the curtain hanging device 17 is passed. As a result, the tile 6 placed on the arm 14 of the moving table 7 passes between the container 19 and the pan 20 of the curtain hanging device 17 and continuously drops from the slit 18 of the container 19 in a curtain shape. Is applied to the surface of tile 6. Further, when the moving table 7 similarly passes through the curtain hanging device 17 of the glaze station C, the glaze is separately applied.

Next, by driving the motor 11 in the opposite direction to the conventional one, the moving table 7 reaches from the glazing station C to the glazed booth 15 of the glazed station A through the glazed station B. In that case, the curtain hanging devices 17 of the glazing stations B and C are made to be the same by the curtain hanging devices 17 by deviating from the range of the loci through which the moving table 7 passes, as shown in FIGS. 5 and 6, for example. No different types of glaze are applied over the tile 6. Of course, conversely, it is also possible to apply the same type of glaze in layers. For example, the glazes of the glazing stations B and C are set to different types, and each curtain hanging device 17 is always exposed within the movement locus range of the moving table 7 as shown in FIG. Accordingly, a total of four layers of different types of glaze may be alternately applied and laminated. When the movable table 7 reaches the inside of the glazed booth 15 of the glazed station A on the return path, the drive of the motor 11 is released and the movable table 7 is stopped. Then, this time, a different type of glaze is spray-applied from the spray device 16. This makes it possible to form at least three glaze layers by coating.

In this way, the moving table 7 is reciprocally moved between the glaze stations A to C, and the glaze layer of the tile 6 is laminated and applied, whereby the total length is significantly shortened as compared with the conventional one-way glaze line. It is possible. For reference, in the case of coating and forming three layers of glaze, the conventional glaze line required at least 20 m, but the glazed line obtained by applying the method of the present invention can be shortened to 10 m.

Of course, if necessary, the moving table 7 is selectively and arbitrarily reciprocally moved between the glaze stations A to C,
A desired multi-layered glaze layer may be formed by coating. Further, it is possible to provide a larger number of glaze stations, and in that case, it is possible to appropriately select a glaze device such as a spray device or a curtain hanging device.

〔The invention's effect〕

As described above, according to the present invention, the moving table having the tile placement portion is freely reciprocated between the plurality of glazing stations, and the desired multi-layered glazed layer is applied at the appropriately selected glazing station. It is possible to form. With such a glaze method, it is possible to significantly reduce the total length of the glazed line as compared with the conventional case. In addition, since it is a glazed line that reciprocates a moving table equipped with a tile placement part, the conveying path of the moving table does not bend, and it is possible to convey at a stable speed at all times. There is no variation in thickness.
