Description

[Detailed description of the invention] The present invention relates to a method for glazing dried beans.

Looking at the continuous manufacturing process for traditional Japanese tiles, we see that clay chips are put into a kneading machine, kneaded, and then extruded into a single strip-shaped Japanese tile base. They are cut to a certain length, press-molded into the desired shape of the Japanese tile base, stacked in multiple stages on the pallets of a drying cart, and transported to the drying room. After this, the drying cart is removed from the drying room. After going through a series of steps, such as hanging one end of the dried beans called Shiroji on the hook of the required trolley conveyor, applying glaze, loading the glazed tile onto a firing cart and firing. , mass production and automation are being promoted.

At that time, when applying the glaze to the dried beans, in the case of the conventional pouring method, the fully dried tiles are hung on the hooks of the trolley conveyor and the glaze is cascaded down from below. It is conveyed upward in a lifting manner. Then, the surface side of the dried beans is pushed into the flow of the glaze, and the glaze is coated in a similar manner, and then pulled up and carried.The applied tile is carried suspended over a long distance, and the glaze is thoroughly removed. I deal with it by doing things. 1+, in the case of the conventional immersion method type,
The glaze is applied by pouring dried beans directly into the glaze tank.

Therefore, in the case of the pouring method, the glaze is usually applied not only over the entire surface of the tile, including the outer edge of the tile, but also around the periphery of the back of the tile. Also,
In the case of the dipping method, the entire outer surface of the tile, including both the front and back sides, is glazed because it is doused. Therefore, although it would normally be sufficient to apply the glaze to the outer surface of the tile or the surface of the tile including the outer peripheral end surface of the tile, since the glaze is applied to the back side of the tile as described above,
More glaze than necessary is always wasted, resulting in a pot of expensive glaze. However, since the glazing must be sufficiently drooped after glazing, the conveying fins become unnecessary and redundant, and since the glazed tile is suspended and conveyed, the upper part of the glazed tile is thin and thin compared to the glazed tile. As a result, the lower part of the glazed tile becomes thicker, making it difficult to obtain a glazed tile with a uniform thickness and no uneven coating.

On the other hand, as is well known, Japanese tiles are stacked tightly together from the bottom to the top of the roof, from one side of the roof to the other, and the roofing is finally done. It will be done.

The present invention was invented in view of the above-mentioned points.
Alternatively, they can be gently overlapped horizontally and vertically, arranged in a row in a shape similar to that of a tiled roof, and then transported to the necessary part of the tile surface of the tiled roof.

By uniformly misting the atomized glaze and leaving the back of the tile unglazed, as well as the part where the dried beans overlap, we minimize the waste of #1'#&.
Efficiently achieves glazing without glaze spots, and furthermore,
The aim is to make the conveyance line more compact by drying the glazed tiles in a short time, and also to eliminate the unevenness of baked soil after firing, which in turn aims to reduce product costs and equalize the quality of Japanese tile products by making them uniform. It is.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

Next, in Fig. 3, which shows an outline of a second embodiment of the present invention, in which dried beans Oo are arranged in a row by gently overlapping each other in the vertical and horizontal directions to form a two-row roof-like tiled roof. The tile roofing device consists of the following configurations. The space is a horizontally installed two-figure support frame), and

are formed in a hanging manner. - is a sufurid conveyor, which conveys a large number of dried beans (a) that are gently stacked vertically and horizontally in two rows of roof-like tiles. During this conveyance process, a glazing room (9) consisting of a first glazing room Q1, a second glazing room (2), a glaze supply device, a mist generator M, and a drying room, as well as the @1 flow side, are installed. 1) hot air 2) air supply pipes, etc. are arranged and configured, respectively. 1m, (57a)

Therefore, 0 ot of dried beans are placed on multiple rows of bale holes directly below the support frame girth of the tile roofing device G) at the imaginary line position in Figure 3.
- Send in a flat drying trolley. Next, the entire tile roofing device including the 7-lay Al4a support is lowered, and the dried beans are
The two rows are formed to hang down from the inside of the fixed support frame (1) and the swing support frame (1), respectively, and are sucked and held by the suction cups (γ) at the lower end of the intake pipe (6), respectively, and pulled up. Then, the entire tile roofing device (2) is turned around in the direction of arrow A around the rotary support (for rotating support), and is moved in the direction of arrow B to move directly above the sufurid conveyor. During or after the reversal, transition, drive cylinder 1 is operated to slide and guide the fixed support frame and the sliding piece for opening the swing support frame to one side of the fixed frame. Two rows of dried beans 001 suction-supported by individual suction cups (7) - each row is gently overlapped in the vertical direction (longitudinal direction) and fitted, and the drive motor 1611 is rotated in the normal direction to move the rotation between the rotation axes. , the arm swings in one direction, thereby swinging the space between the swinging support frames toward the fixed support frame in a lifting manner. In this way, as shown in Figure 4, the two rows of dried beans rxJ are placed on the source side (b) of one dried bean ■, and also gently in the lateral direction (width direction) where the side side (a) of the other dried bean ■ is covered. At this stage, the support frame is lowered and the suction force of the suction cup (1) is released, thereby creating a roof-like tiled roof on the two rows of dry tile roof stut conveyor. Place it and transport it.

In this way, the two rows of tiled roofs were dried, and the next glazing room (

After wiping away dust, etc. on the surface of the tiles by ventilation,
The glaze is sent into the glazing chamber (9), and in the first glazing chamber α and second glazing chamber (121) in the glazing chamber (9), glaze is applied to the exposed surface of the dry 1 tile in the tile roofing state 1. The glazed tiles (Xl) thus treated with glaze are sent into the drying room (9) in two rows of tiles through the air curtain-1 at the outlet. The drying chamber is dried with hot air for a short time and sent out of the drying chamber.This is carried out by two rows of belt conveyors (57a) branched at the rear end of the slant conveyor. As shown in the figure, the glazed tiles (XI) are separated into two rows, and then the glazed tiles (XI) are individually separated and conveyed individually by the belt conveyor (58a) as shown in Figure 6. . On top of that, the glazed tiles (XR) are made by the autochat car at the rear.
Launched.

It is suspended and supported on a trolley conveyor and transported to the loading process onto a baking cart.

In addition, as a modification of the second embodiment, after glazing the two rows of roof tiles, the belt conveyor moe s (5
7a) is separated and further transferred to a conveyor belt of 1581° (38
Although a) is arranged in series so that the glazed tiles (Xl) are separated and dried, this does not change the gist of the present invention in any way.

Furthermore, if the glazed state of the glazed tile (Xi), α1) that has been mist coated by the steps shown in the second embodiment is shown separately, it is shown in FIGS. 7(a), (b), and (cl). As shown, the tiled roof is shaped like a roof (the part where the stacked dried beans ② sink in is unglazed, and the exposed surface is uniformly glazed).

The present invention is a method of drying, which consists of various steps such as stacking a large number of dried beans to form a roof-like tile roof as described above, atomizing the glaze, and applying the glaze by misting the exposed surface of the tile. Since we used the bean glazing method, the glazing process on the tile surface is even.
Moreover, it is done without applying the glaze, and while the glaze is applied to the surface of the tiles in a roof-like tile roofing state, the glaze is not applied to the submerged or overlapping parts, which eliminates waste of glaze and reduces the amount of expensive glaze used. Enables savings. In addition, since the mist coating ensures a uniform and spotless coating on the tile surface, there is no room for drying spots and it is possible to dry in a short time, resulting in a uniform finish after firing. In addition, the small drips are effectively removed, which in turn brings about performance effects such as contributing to reduction of product cost and further improvement of quality.

In particular, its advantages over previous glazing methods are as follows.

(b) The amount of glaze decreases.

In the case of the conventional pouring method type or dipping method type, it is necessary to fill a tank with several times as much glaze as the amount required to glaze the dried beans, or pour it onto the dried beans1. In the case of this glazing method, since the dried beans are placed in a row in a tiled state and subjected to mist glazing, there is no loss of glaze and the required amount of glazing can be used.

(b) The coated surface becomes uniform and clean◎ Dried beans are conveyed on a conveyor in a flat #I pattern with a tile roof and are coated with mist, so when immersed in a tank using the immersion method. There is no shaking of the tiles or variations in the timing of glazing due to the pouring method.

All tiles can be glazed in a uniform, spotless pattern.

In particular, in the case of the pouring method, it is necessary to suspend the glaze on a trolley conveyor and cut off the drippings sufficiently.
The glaze was thin on the top and thick on the bottom, and was more likely to occur after glazing in the vertical direction of the tile.

(F) Eliminates glazing mistakes.

In the conventional pouring method, the glazing tip becomes clogged, which often results in mistakes in glazing.However, according to the present method, such mistakes are eliminated and the yield of glazed tiles is significantly improved.

) There is little change in the glaze components.

In the case of traditional glazing methods, multiple layers of glaze are circulated, so
Spots tend to appear in the flow of the glaze after glazing due to changes in the temperature of the glaze, but with the amount of glaze used in this device, such unevenness μ is unlikely to occur. b0 (e) The device can be made smaller. .

Because the amount of glaze used is much less than the conventional method,
The glaze tank, feed pump, glaze supply tank, stirring device, etc. can also be small and small in capacity.

(f) It is easy to change the glaze color and clean the equipment.

Since the amount of glaze used is small and there is no surplus, the booth can be cleaned in a short time and the glaze color can be easily changed.
It also contributes to reducing work time.

(g) The working environment will be improved.

Traditional glazing departments have a strong image of being dirty places, with glaze splatter scattered everywhere and piles of poorly glazed tiles. With this device, such drawbacks are eliminated and the working environment is significantly improved.

(Ao) It is possible to shorten or abolish the trolley line.

In the case of the conventional glazing method, a long-distance drying trolley line is indispensable in order to allow the glazed tiles to drip sufficiently and move around the kiln. The glazing process and drying process are installed side by side, eliminating the need for a trolley line for drying, and even if the product is transported over the kiln for preheating drying, the transport distance is significantly shortened. .
