Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is applied to a continuous manufacturing plant for tiles installed on walls and interiors of buildings and houses, in which excessive amounts of glaze are applied to the surface of the unglazed tile material. It relates to a mechanism for scraping glaze.

[Prior art]

In a conventional tile continuous manufacturing plant, a mechanism for scraping excess glaze when applying glaze to unglazed tile material is performed by a belt-type scraping mechanism whose side surface is arranged laterally in the traveling direction of the conveyor belt. Was scraped off by a two-sided scraper supported from above.

Therefore, since the scraping mechanism protruding from the left and right of the conveyor belt scrapes the left and right surfaces of the unglazed tile material,
There was a problem that the unglazed tile materials could only be arranged in one row on the conveyor belt.

Therefore, it is necessary to process a plurality of unglazed tile materials at once by providing a large number of conveyor belts 16 for one row of tiles, which causes a problem that the continuous manufacturing apparatus becomes wide. Of.

[Issues to be solved by the device]

The present invention is capable of scraping glazed and excess glaze while arranging and transporting unglazed tile materials in a plurality of rows on one conveyor belt. By arranging the tiles, it is possible to carry out glaze and scrape off excess glaze, so that they can be conveyed to the wide tile baking furnace in multiple rows as they are.

[Means for solving the problem]

The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

When the glaze is applied, the conveyor belt 16 that conveys the unglazed tile material 4 is intermittently driven, and when the conveyor belt is stopped intermittently, the excess glaze 3a on the four sides of the unglazed tile material 4 after glaze
Remove the two side scrapers 5 and 6 from the conveyor belt 16
Of the biscuit tile tile 4 when adsorbing and fixing the biscuit tile material 4 at the time of scraping, and after scraping off the excess glaze 3a on the front and rear sides by the two side scrapers 5 and 6. The suction device 7 is rotated 90 degrees, and the remaining two sides are scraped in the return stroke of the two-sided scrapers 5 and 6.

[Action]

Since the present invention is constructed as described above, it has the following effects.

The unglazed tile material 4 after the glaze 3 is evenly glazed by the curtain hanging device 19 on the glazed conveyor belt 1 is the conveyor belt 1
6 is transferred.

The conveyor belt 16 is driven intermittently, and when stopped, the two side scrapers 5 and 6 attached to the scraping device support 9 are moved orthogonally to the conveyor belt 16 so that the front and rear surfaces of the biscuit tile material 4 are first crossed. Excessive glaze 3a protruding out,
It is scraped off by a rotating belt.

Next, the suction device 7 which supports the lower side of the bisque-tiled tile material 4 by the vacuum suction device 11 is rotated by 90 degrees by the rotation drive device so that the left and right surfaces of the bisque-tiled tile material 4 are positioned in the front-rear direction, and the two sides of the return stroke The scrapers 5 and 6 scrape off the excess glaze 3a on the left and right sides, which is newly formed on the front and rear sides.

〔Example〕

The problems to be solved and the means for solving the problems of the present invention are as described above. Next, the structure of the embodiment shown in the accompanying drawings will be described.

The overall structure of the tile continuous manufacturing plant will be described with reference to FIG.

A tile material is formed by forming and pressing the tile material soil, and the tile material is placed on a roller conveyor that passes through the biscuit oven, and the biscuit tile material 4 is obtained while passing through the biscuit oven.

The unglazed tile material 4 is conveyed by the conveyor belt 21 and transferred onto the glazed conveyor belt 1. A supporting protrusion is projected on the glazed conveyor belt 1, and a curtain-shaped device 19 reciprocates in a direction perpendicular to the traveling direction of the glazed conveyor belt 1 in a state of being mounted on the supporting protrusion. Then, the glaze 3 that falls is uniformly applied.

The curtain hanging device 19 includes a curtain hanging cylinder 17 and a guide rod 18.
Thus, the glazed conveyor belt 1 on which a plurality of rows, for example, 14 rows of unglazed tile materials 4 are arranged, is reciprocated.

The glazed transport belt 1 is stopped while the drape is applied by the drapery device 19, and the glazed transport belt 1 is configured to be intermittently driven by signal control from the controller 15.

Further, in the embodiment shown in FIG. 1, the curtain hanging device 19 is configured to hang two horizontal rows at a time, and one round trip of the curtain hanging device 19 makes four horizontal rows of biscuit tile material 4 in total. It is possible to hang the line.

A cleaning mechanism 20 for cleaning the glazed transport belt 1 is provided on the lower surface of the glazed transport belt 1, and the glaze transport belt 1 in a colored state is moved downward by the glaze 3 flowing down on the upper surface of the glazed transport belt 1. In order to easily change the color after cleaning.

It is the pressure control device 22 that controls the timing of expansion and contraction of the curtain cylinder 17.

On the glazed conveyor belt 1, a plurality of rows of biscuit tile material 4
The glaze 3 is hung on all of the tiles. At this time, as shown in FIG. 7 and FIG.
The excessive glaze 3 that has flowed down from the end portions of the four sides becomes the excessive glaze 3a and drips.

If the excess glaze 3a is left in the tile baking furnace 2 and baked as it is, the tile becomes a defective tile in which the width of the side surface is not uniform, and the drip of the glaze is conspicuous in terms of design.

In the present invention, the portion of the excess glaze 3a generated when the curtain is hung is scraped off.

As shown in FIG. 1, the unglazed tile material 4 after being glazed on the glazed conveyor belt 1 is transferred onto the conveyor belt 16. Since the conveyor belt 16 is transferred in a state of being arranged in 14 rows, in order to scrape off the excess glaze 3a on the left and right surfaces in the traveling direction of the biscuit tile material 4 and the front and rear surfaces, the moving direction is set. Two types of two-sided scraper with different 5
・ 6 must be placed.

However, in the case of the present invention, the suction device 7 supporting the unglazed tile material 4 can be rotated by 90 degrees, so that the excess partial scraping mechanism after the glazed tile is constituted by only one set. .

The excess scraping mechanism after the tile is glazed is composed of a scraping cylinder 12, a scraping guide rod 14, and a scraping device support 9 which reciprocates in a direction traversing the traveling direction of the conveyor belt 16 by the scraping cylinder 12 and the scraping guide rod 14. .

The scraping cylinder 12 is supported by the controller 15 and controlled by the pressure control device 21 so that the scraping cylinder 12 reciprocates left and right when the intermittent driving of the conveyor belt 16 is stopped.

The curtain cylinder 17 and the scraping cylinder 12 may be expanded and contracted by air pressure, may be hydraulic, or may be reciprocated by an electric motor.

Next, referring to FIGS. 2 and 3, the structure of the scraping device support 9 and the two side scrapers 5 and 6 will be described.

One side of the scraping device support 9 has two side scrapers 5
Four sets of 6 are supported, and with the configuration of FIG. 2, it is possible to scrape off the excess glaze 3a of the four horizontal rows of unglazed tile material at a time.

The supporting part of the biscuit tile material 4 in the part where the scraping device support 9 reciprocates is constituted by a suction device 7, and the suction device 7 is sucked from below by a vacuum suction device 11 to form two side surfaces. Even when scraping with the scrapers 5 and 6, the biscuit tile material 4 is configured so as not to move back and forth and to the left and right.

The suction device 7 is controlled by the lower 90-degree rotating mechanism 10 so as to rotate by 90 degrees together with the forward movement of the two-side scrapers 5 and 6.

Then, first, as shown in FIG. 5, after the excess glaze 3a on the front and rear surfaces is scraped off by the two-sided scrapers 5 and 6, the suction device 7 is rotated 90 degrees, and this time, the excess glaze on the two sides that had been left and right up to that time. 3a is scraped off.

The two-sided scrapers 5 and 6 are configured so that a file-shaped belt coated with gold sand or the like can rotate in the vertical direction.
It is configured so that it will not be worn by scraping off the excess glaze 3a.

As the two side scrapers 5 and 6 rotate, the glaze 3 protrudes from the shape of the biscuit tile material 4 as shown in FIGS. 9 and 10 without adversely affecting the glaze 3 on the surface of the biscuit tile material 4. However, the unglazed tile material 4 coated with the glaze 3 could be obtained.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

First, the scraping cylinder 12 of the scraping device support 9
The excess glaze 3a that can be formed on all four sides of the biscuit tile material 4 can be removed by the reciprocating motion of the tiled material 4, so there are two sets of front and back and left and right sides of the excess part scraping mechanism after the tile is glazed. There is no longer any need to do it.

Secondly, the two side scrapers 5 and 6 that reciprocate at right angles to the traveling direction of the conveyor belt 16 can scrape off the excess glaze 3a of the conveyed unglazed tile material 4, so that the unglazed tile material 4 can be removed. Can be formed into a large number of rows, and the large number of rows can be used for the roller conveyor 2 of the tile firing furnace 2.
Since it can be configured in multiple columns with a full width of 5,
By setting the widths of the glazed transfer belt 1 and the transfer belt 16 to the full width of the roller conveyor 25, one linear transfer line can be formed.

Conventionally, the line width of the glazed conveyor belt 1 or the conveyor belt 16 can be only about 4 rows, and the width of the roller conveyor 25 can be about 20 rows. Therefore, the conveyor belt 16 should be orthogonal to the roller conveyor 22. Then, four rows above the conveyor belt 16 were laid sideways and 20 rows were separated and transferred to the roller conveyor 25 side.

In the case of such a conventional configuration, there is a problem that the conveyor belt 16 and the roller conveyor 25 need to be orthogonal to each other, which limits the arrangement of the tile continuous manufacturing plant.

The present invention was able to improve this point.
