Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a novel glazed tile body side surface finishing process that removes excess glaze adhering to the peripheral side surface of a glazed tile body whose surface is glazed. It is related to the device.

"Prior Art" During the tile manufacturing process, the coating on the surface drips and adheres to the peripheral side surface of the glazed tile body after glazing. Conventionally, the equipment members shown in Figs. 3 and 5 have been used to remove excess glaze as described above.
I found something like the one shown in the picture.

The surplus glaze removal device member 1 shown in FIG.
are installed on both sides of the tile conveyance path 3. The scraping belts 2, 2 are moved annularly as shown by arrows in the figure by appropriate rotational drive means (not shown). In this surplus glaze removal device member 1, the glazed tile element body 4 is
While being conveyed above, when passing between the two scraping belts 2, 2, the scraping belt 2 comes into contact with the side surface of the scraping belt 2 and scrapes off the excess glaze.

The surplus glaze removal member 7 shown in FIG. 5 is simply a rectangular parallelepiped-shaped sponge 5, 5 that maintains a water-containing state and is fixed on both sides of the tile conveyance path 3. The excess glaze is wiped off by the conveyance passage in step 4. In addition, the symbol 6 in the figure
is a water supply pipe that supplies water to the sponges 5, 5.

"Problems to be Solved by the Invention" FIG. 4 is a partial front view of the surplus glaze removing device member 1 shown in FIG. 3. As shown in the figure, the scraping belts 2, 2 of the surplus glaze removal device member 1 move in a circular manner from the surface edge 4a of the glazed tile element body 4' toward the conveyance seat edge 4b, as described above. However, this method has the disadvantage that the excess glaze that has been scraped off is rubbed against the surface edge 4a of the glazed tile body 4' again. Furthermore, when using this surplus glaze removal device member 1 to finish the side surface of a glazed tile body 4' having a large thickness, such as a two-split glazed tile body or an accessory tile body, for example, As shown in the figure, the scraping belts 2, 2 come into contact with the surface edge 4a of the glazed tile element body 4' and the conveyor seat edge 4b and are bent in an arched shape, causing the glazed tile element body 4'
The excess glaze that adheres to the center of the side surface cannot be removed. The above phenomenon tended to increase as the thickness of the glazed tile body 4' increased, and as the pressing force for bringing the scraping belts 2, 2 into contact with the glazed tile body 4' increased.

On the other hand, since the parts of the sponges 5, 5 of the surplus glaze removal member 7 as shown in FIG. The wear condition of 5a becomes uneven. For this reason, as shown in FIG. 6, the sponge 5 comes to bite into and come into contact with the surface edge 4a of the glazed tile body 4, and the sponge 5 comes into contact with the surface glazed portion.
There were scratches caused by. Further, although the sponge 5 is always kept in a water-containing state by the water supply pipe 6, the pores of the sponge 5 become clogged with the glaze that has been wiped off, and the sponge 5 becomes dry within a short period of about one hour. 5 had to be removed and cleaned, and this cleaning work was carried out periodically.

``Object of the Invention'' The present invention has been made in view of the above-mentioned circumstances. At the same time, we have developed a new glazed tile body side finishing device (hereinafter referred to as this book) that keeps the scraped surface for excess glaze always ready for scraping and prevents the removed glaze from adhering to the surface of the glazed tile body again. The purpose of the invention is to provide an inventive device.

"Structure of the Invention" (Means for Solving Problems) The scraping surface of the surplus glaze scraping member is brought into full contact with the side surface of the glazed tile body, and is directed from the edge of the glazed surface to the edge of the conveying seat surface. Made it move tilted. Further, the scraping surface of the surplus glaze scraping member is formed of a soft porous material, and the glaze cleaning member impregnates and removes the glaze cleaning liquid from the scraping surface located outside the scraping area of the glazed tile body. has been added.

(Function) Since the scraped surface of the excess glaze scraping member is in full contact with the side surface of the glazed tile body, uneven wear of the scraped surface is prevented. In addition, the scraped surface is inclined with respect to the side surface of the glazed tile body, and the moving direction is an inclined direction from the surface edge of the glazed tile body toward the conveyance seat surface, so that the glazed tile is always It acts to press the element body against the conveyance surface of the tile conveyance path. Therefore, there is no need to provide special floating prevention means for the glazed tile element in the tile conveyance path.
Furthermore, by attaching a glaze cleaning member to the scraped surface, the scraped surface can always be kept ready for scraping.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a perspective view showing the main components of the apparatus of the present invention. In the apparatus of this embodiment shown in the figure, two apparatuses of the present invention are installed on both sides of a tile conveyance path 3, respectively. As shown in the figure, the apparatus of the present invention consists of a surplus glaze scraping member 8 and a glaze cleaning member 9.

The surplus glaze scraping member 8 is mainly composed of a rotatable sponge roller. FIG. 2 is an enlarged side view of FIG.
The state of contact with is shown by the two-dot chain line. As shown in the figure, the excess glaze scraping member 8 is installed so that its rotation axis 12 is inclined with respect to the conveyance direction of the tile conveyance path 3. Of the rotating circumferential surface of the surplus glaze scraping member 8, the surface that can come into contact with the side surface of the glazed tile body 4 transported by the tile transport path 3 (shown with hatching in the figure) is defined as the scraped surface 8a. The degree of inclination of the surplus glaze scraping member 8 is adjusted so as to satisfy the following conditions. That is, this scraped surface 8a is larger than the excess glaze scraped member 8 with respect to the thickness dimension t of the side surface of the glazed tile body 4.
The thickness dimension b of the two contacts is such that the entire width thereof is in contact with each other. In addition, when adjusting the degree of inclination, the surplus glaze scraping member 8 having a constant thickness dimension b may be inclined with respect to the thickness dimension t of the glazed tile body 4; Preferably, the surplus glaze scraping member 8
The angle θ between the rotation axis 12 of the
60°), and at this time, the excess glaze scraping member 8 has a thickness dimension b that satisfies the above conditions.
It is better to choose.

In FIG. 1, the glaze cleaning member 9 includes a supply member (not shown) that impregnates the surplus glaze scraping member 8 with a suitable glaze cleaning liquid, and a squeezing roller 10 that removes the glaze cleaning liquid.

The squeezing roller 10 is a hard shaft-shaped member that is rotatable, and is installed so as to press against the rotating circumferential surface of the excess glaze scraping member 8. The position where the squeezing roller 10 is installed on the rotating circumferential surface of the surplus glaze scraping member 8 is on the scraping surface 8.
A is a portion located outside the scraped area with the glazed tile body 4.

The supply member has a supply pipe 11 that guides the glaze cleaning liquid to the excess glaze scraping member 8. The position facing the outlet of the supply pipe 11 is such that the scraping surface 8a of the surplus glaze scraping member 8 rotates and extends from the scraping area with the glazed tile body 4 to the installation location of the squeezing roller 10. It is preferable to set it between. In the apparatus of this example, ordinary water was used as the glaze cleaning liquid.

In the apparatus of the present invention constructed as described above, the rotation direction of the surplus glaze scraping member 8 is determined in relation to the direction in which the surplus glaze scraping member 8 is inclined with respect to the conveyance direction of the glazed tile body 4. It is being For example, when the glazed tile body 4 is transported as indicated by arrow A in FIG. The direction of rotation is as shown by arrow B. That is, the rotation direction of the surplus glaze scraping member 8 is an inclined direction from the leading edge of the surface of the glazed tile body 4 toward the trailing edge of the conveyance seat surface. However, the direction of rotation and inclination of the glazed tile body 4 does not need to be limited as in this embodiment. For example, in FIG. , the direction may be from the trailing edge of the surface of the glazed tile body 4 toward the leading edge of the conveyance seating surface.
However, in this case, it is desirable that the rotation speed of the excess glaze scraping member 8 is set to several times the conveyance speed of the glazed tile body 4.

(Study of Alternative Embodiments) The detailed configuration and shape of each part of the device of the present invention can be changed as appropriate depending on the embodiment. In addition, although illustrations and explanations are omitted, when finishing the entire circumferential side surface of a glazed tile body using the device of the present invention, the device of the present invention is installed upstream and downstream of the tile conveyance path, and the distance between these two devices is A direction changing mechanism that rotates the conveying direction of the glazed tile body by 90 degrees may be installed in the tile.

"Effects of the Invention" As is clear from the above explanation, according to the glazed tile body side surface finishing device according to the present invention, the scraped surface for excess glaze is in full contact with the side surface of the glazed tile body. Therefore, the scraped surface wears uniformly over its entire surface. Therefore, the scraped surface will not dig into and come into contact with the surface of the glazed tile body, and the surface edge will not be scratched or the glaze that has been scraped off will not adhere again. Moreover, since the scraped surface is formed of a soft porous material, it closely contacts the shape of the side surface of the glazed tile body. Therefore, even if the glazed tile element has a large thickness, such as a two-split glazed tile element or an accessory tile element, it is possible to finish the side surface thereof. Moreover, since the glaze cleaning member impregnates and removes the glaze cleaning liquid into the pores inside the surplus glaze scraping member, the scraping surface can always be prepared for scraping. , has many excellent advantages.
