Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method for continuously manufacturing tiles.

(Prior art and problems to be solved by the invention) The entire tile manufacturing process includes a molding process for molding the tile, a glazing process for applying glaze to the surface of the molded tile (in the case of glazed tiles), and a glazed tile. The process includes a drying process to dry the tiles and a molding process to fire the tiles, but in the past, this drying process was generally set up separately and separately from the main production line that connects the molding process, glazing process, and firing process. ,
For this reason, it is necessary to move conventionally glazed tiles from the main production line to the drying process, or to return the dried tiles to the main production line, which complicates the entire tile production process and increases the work involved. There were problems such as it was complicated and the work efficiency was poor.

In addition, in the tile manufacturing process, a certain amount of dried tiles is stored at the stage before firing, but in addition to the drying process being provided separately and independently, such stocking This necessity has been an obstacle to automating the entire tile manufacturing process.

(Means for Solving the Problems) The present invention has been made to solve the above problems, and the gist thereof is a tile molding process, a glazing process of applying glaze to the surface of the molded tile, and , a firing process for firing the glazed tiles is incorporated on one production line, and a drying/stocking process for drying and storing the glazed tiles is connected in series on the production line between the glazing process and the firing process. This is because it was established in

(Function) In this way, there is no need to transfer the tiles flowing along the production line connecting the forming process, glazing process, and firing process to the drying process or vice versa, thereby simplifying the tile manufacturing process. This will also make your work more efficient.

In addition, in the present invention, the drying process also serves as a stocking process, so the space previously required for these processes is reduced and the process is shortened.
Furthermore, since the stocking process is provided in series on the production line, there is no need to stop the line even if trouble occurs on the upstream side of the line. This is because it is sufficient to sequentially send out the tiles stored in the stocking process.

In this way, according to the present invention, each process necessary for tile manufacturing is integrated on one line,
Furthermore, even if a problem occurs, there is no need to stop the line, making it easier to automate the tile manufacturing process.

In the present invention, various means for stocking the tiles on the production line can be considered, but as the tile transport means, one having a shelf for transporting the tiles on the top surface and a feeding mechanism for transporting the shelf is used. If the tiles are transported in a state where they are stacked on shelves, the tiles can be easily stocked, and the tiles can also be easily dried during the storage.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

Figure 1 shows a continuous tile production line, where A is the tile forming process, B is the primary drying process of the molded tiles, C is the glazing process of applying glaze to the surface of the primary dried tiles, D is a secondary drying/stocking process, and E is a firing process for firing the tiles. As shown in the figure, the production line in this example consists of three columns, I, and.

In the forming process A, dry press forming of the tiles is performed, and the formed tiles are conveyed to the shelving station 10 according to the arrow a, where they are adsorbed by a suction device and placed on the transport shelf 12 (Fig. 5). can be transferred to the top.

The shelf 12 has a rectangular planar shape as shown in FIG. The support bars 16 are stretched over each other, and the support bars 16 are connected by a connecting rod 18, so that the tiles can be arranged on the support bars 16 without gaps.

The shelves 12 on which the tiles are placed at the shelving station 10 are sent in the direction of arrow b to the stacking station 20, where they are stacked into multiple tiers by a transfer machine 22. Figure 6 shows the transfer machine 22.
A simplified configuration is shown. As shown in the figure, this transfer machine 22 includes a pair of gripping arms 24 that grips or releases the pair of frames 14 of the shelf 12 from both the left and right sides, and an elevating cylinder 28 that moves the gripping arms 24 up and down under the guidance of a guide rod 26. and a main body 3 that supports the gripping arm 24 and the lifting cylinder 28.
0 and a guide 34 provided on the frame 32 to guide the movement of the main body 30 in the front and back direction, and a pair of left and right gripping arms 24 grip the shelf 12 from both the left and right sides and lift it with the lifting cylinder 28. After the main body 30 is raised and further moved along the guide 34, the lifting cylinder 28 lowers the shelf 12 and the gripping arm 24 releases the shelf 12, thereby stacking the shelves 12 one by one.

The shelves 12 stacked in this way are then sent to a primary drying step B, where the tiles are primarily dried. The shelves 12 that come out of the primary drying process B in a stacked state are then disassembled into individual shelves 12 at a shelf disassembly station 36, and then sent to the glazing process C. In this glazing process C, as shown in FIG.
A slurry-like glaze is sprayed from step 8, and the glaze is applied to the surface with a constant thickness. The glazed tiles 60 on the shelf 12 then reach the stacking station 40 again, where they are again stacked by the transfer machine 22 and then sent to the next second drying process/stocking process D. It will be done. This second drying process and stocking process D
, while drying the glazed tile 60,
This is a process for storing a certain amount of tiles 60 at a stage before firing, and a simplified configuration of the apparatus is shown in FIGS. 8 and 9. In the figure, reference numeral 42 denotes a tunnel-shaped drying chamber, which extends from the rear of the I-th row to almost the entirety of the I-th row. Drying room 42
Conveyance rollers 44 are disposed at the bottom of the frame 46 and supported by a frame 46, and a cart 47 and a plurality of shelves 12 stacked on top of these conveyance rollers 44 are disposed at the bottom of the frame 46.
is sent at a constant speed. Further, a window 52 consisting of a transparent glass 48 and a frame 50 is provided on the side surface of the drying chamber 42, so that the condition inside the drying chamber can be visually checked from the outside. Hot air is sent into the drying chamber 42 through a duct (not shown), so that the tiles 60 are dried in a stacked manner.

In this process D, a large number of tiles 60 are stacked in long rows compared to the amount that can be accommodated in a firing furnace (roller hearth kiln) 58, which will be described later. It is used for both purposes.

Now, the tiles 60 that have been transported inside the drying chamber 42 are
It reaches the shelf take-out station 54, where the stacked shelves are taken out one by one from the bottom side.
Subsequently, it is transported in the direction of arrow e and reaches the separation station 56. Then, the tiles 60 on the shelf 12 are sucked by the suction device and placed on the rollers of the first row. The tile 60 placed on the roller is conveyed in the direction of arrow f and enters a roller hearth kiln (RHK) 58, and then conveyed inside the roller hearth kiln 58 in the direction of arrow g and is fired in the process. Ru.

On the other hand, the empty shelves 12 are indicated by dashed arrows h, i,
It is sent in the directions shown by j and k and returned to the original shelf loading station 10 (the conveyance path of the empty shelf 12 is provided on the lower side of the conveyance path of the shelf 12 on which the tiles are placed), and there again. The tiles are used for conveying tiles and are sent in the direction of arrow b.

As described above, in this example, process D serves as both the drying process and the stocking process of the glazed tiles 60, and is directly connected to the tile manufacturing line, so that the molding process A on the upstream side and the shelf Placing station 10, stacking station 20, glazing process C
Even if a trouble occurs in the above process, tiles 60 can be continued to be supplied to the roller hearth kiln 58, and the tile manufacturing line will not be stopped.

Additionally, the drying process, which used to be a separate process, is now directly connected to the production line, making work more efficient.
Furthermore, automation of a series of manufacturing steps from molding to firing of the tile 60 can be realized.

Although the embodiments of the present invention have been described in detail above, this is merely an example of the present invention, and the tile forming method,
The present invention can be implemented with various modifications without departing from the spirit thereof, such as the glazing method, tile stocking method, etc., which may be modified as necessary.

(Effects of the Invention) As described in detail above, according to the present invention, the tile manufacturing process is simplified, the work content is simplified, and the work efficiency is improved.

In addition, in the present invention, the drying process also serves as a stocking process, which reduces the space previously required for these processes and shortens the process.In addition, the drying process also serves as a stocking process, which shortens the process. This makes it easier to automate the entire tile manufacturing process.

In the stocking process, if the tiles are placed on shelves and transported in a stacked state, the stocking and drying of the tiles can be easily carried out at the same time.
