Description

[Detailed description of the invention] The present invention aims to solve the following problems.

(Industrial Application Field) This invention relates to a method for removing unnecessary substances attached to the bottom surface of a tile, which can be used in the process of making a molded tile into a product after applying a glaze or the like to the top surface of the tile. It is something.

(Prior Art) In the process of transporting tile materials on a conveyor, there is a task of applying glaze to the tile materials. In such work, it is natural that the glaze adheres to the surface of the tile material, and sometimes it also adheres to the back side of the tile, resulting in the production of tiles with the back side stained. Since such soiled tiles are not desirable as commercial products, improvements have been desired.

(Problems to be Solved by the Invention) Except for the above-mentioned conventional problems, the present invention does not require any change in the transport state of tile materials (also simply referred to as tiles in this specification) during the process of transporting them by a conveyor. To provide a method for removing unnecessary matter adhering to the bottom surface of a tile, which enables the bottom surface of the tile to be sent out by wiping the bottom surface cleanly.

The configuration of the present invention is as follows.

(Essay means for solving the problem) The present invention takes the measures as described in the claims above, and its operation is as follows.

(Function) The tiles are placed on a conveyor and transported. During the transfer process, a wiping belt provided on the side of the conveyor comes into contact with the bottom surface of the tiles.

In that case, when the tile is pressed against the transfer surface on the upper surface of the conveyor by air pressure, and the elastic wiping surface on the upper surface of the wiping belt is compressed by the lower surface of the tile, the tile continues to be transferred. The underside is wiped clean with the wiping surface.

(Example) Below, drawings showing examples of the present application will be described. Reference numerals 1, 2, and 3 are conveyors for transportation, for example, a belt conveyor is used. In these conveyors, 4.5, 6.7 are Goo L8, 9. IO is a conveyor belt, and each belt is used, and the upper surface of these belts is the transfer surface. Each of the conveyors 1, 2.3 is driven by a drive device (not shown) to transport the tiles in the direction of the arrow. Note that the width of each of the above-mentioned conveyors is configured so that the convergence of tile A is also slightly narrower.

Next, U indicates a wiping device. In this, 12, 13
14 indicates pulleys, and L5 indicates a wiping belt wound around these pulleys. This wiping bell 15 has a cross-sectional structure as shown in FIGS. 3 and 3. That is, 16 is a base material, which is made of a material that is strong in tension and has flexibility. 3 is a wiping member attached to the base material 16, and is made of an elastic material.

For example, a porous sponge is used, but a brush-like structure may also be used. The number indicates the wiping surface on the top of the wiping member. The above-mentioned wiping bell) 15 is disposed on the side of the conveyor 2 so that the wiping surface speed is slightly higher than the transfer surface 9a of the conveyor 2 (for example, about /IEI). It moves at a speed different from the movement speed of 9. For example, the speed is half the speed of the belt 9, but it moves in the same direction. However, even if it is set to other speeds, the speed of the movement of the belt 15 is the same as the movement of the V-belt 9. You can also increase the speed. Further, the direction of movement thereof may be opposite to that of the belt 9. Furthermore, two of the above-mentioned wiping bells 15 are arranged in parallel, and are arranged so that the edge of the tile A just rests on them as shown in FIGS. 3 and 3. 19 is a tank for washing water, and inside it is filled with washing rice for washing L5.
The wiping bell) 15 is designed to submerge in this washing water. 4 is a suction duct, and an opening 22 provided at one end thereof.
It is located between the Hiro belts 9 and 9. A communication part provided at the other end of the suction duct 4 is connected to a suction device not shown.

In the structure described above, tiles that have been conveyed from a previous process (for example, a glaze application process) to a conveyor l are passed onto the transfer surface of a conveyor 2, and are transferred by the conveyor 2 in the direction of the arrow. During this transfer process, both edges of the tile man eventually rest on the opposite side of the wiping bell 15. In this case, since the suction duct 4 is always sucking air through its opening ρ, the air pressure below the tile A becomes negative pressure, and the lower surface of the tile A is pressed against the transfer surface 9a as shown in Fig. It will be done. Therefore, the lower edge of the tile's edge is compressed downward as shown in the figure.

Since the lower surface of the tile person is pressed against the transfer surface 9a, the tile person is continued to be transferred by the conveyor 2. In the process, since the moving speed of the bell) 15 is different from the moving speed of the belt 9, the wiping surface of the wiping bell) 15 is wiped on the lower side of the edge of the 18-line tile A, and the glaze etc. adhering to it is rubbed off. Drop it. The tile A whose lower edge surface has been wiped as described above is eventually transferred from the conveyor 2 to the conveyor 3 and sent to the next process. The above-mentioned wiping operation is performed on the tiles sent one after another, and a large number of tiles are sent to the next process with the lower edges of the tiles cleanly wiped. In the above case, L5 is the wiping bell (which is dirty by wiping the lower side of the edge of tile A), which is tank 1.
It is thoroughly cleaned with the washing water added in 9, so that a clean wipe surface is always in contact with the lower surface of the edge of the tile.

Next, in FIG. 1, reference numeral 6 indicates a turning device, which is a device that turns the tile person 90 degrees in a horizontal plane. ue indicates another wiping device disposed downstream of the turning device. This wiping device has the same structure as the wiping device ① described above.

When such a turning device 5 and another wiping device 11e are provided, the underside of the edge around the entire periphery of the tile A can be cleaned by passing the tile person through the wiping device u1 turning device and the wiping device lie in order. The tile can then be sent to the next process (e.g. firing process).

Next, in the above embodiment, an example was shown in which negative pressure was applied to the bottom side of the tile as a means of pressing the bottom surface of the tile against the transfer surface of the conveyor using air pressure, but instead, positive pressure could be applied to the top side of the tile. good.

That is, an air outlet that blows air downward is provided above the transfer path of tile A, and air is blown from the air outlet toward the upper surface of the tile person moving below it. Accordingly, the tile person may be pressed against the transfer surface of the conveyor.

(Effects of the Invention) As described above, in the present invention, in the process of transferring L1 tile A, the tile is placed on the conveyor 2 and transferred, and in the process of transfer, the bottom surface of the tile is wiped and Because it is wiped from the top,
It has the advantage of being able to clean the bottom surface of the tile while maintaining the state in which the tile is being transported.

Moreover, in that case, the tiles in the process of being transferred are forcibly pressed against the transfer surface 9a on the top surface of the conveyor by air pressure, gaining a force in the transfer direction, and also come into strong contact with the elastic wiping surface on the top surface of the wiping belt. , the bottom surface of the tile is simultaneously pushed in the direction of conveyance by the conveyor and wiped with strong force by the elastic wiping theory, while achieving the main purpose of tile conveyance mentioned above. Another great feature is that the underside can be wiped very cleanly.
