Description

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

(Prior Art) In the process of applying a slurry-like glaze to the surface of a tile, the tile is generally conveyed by being placed on a plurality of cord-like belts 102 as shown in FIG. A method is used in which the tile 100 is placed on top of the tile 100 and transported, and a slurry-like glaze is sprayed by a spray device onto the transported tile 100 to apply the glaze to the surface of the tile.

By the way, the cord-like belt 102 allows the tile 1 to be
When conveying 00, it is necessary to arrange the cord belts 102 relatively closely in order to keep the tiles 100 in a stable posture during conveyance, and to prevent the left and right, front and rear tiles 100 from interfering with each other. , it is necessary to leave space between the tiles 100 on the left and right and front and back.

However, in this case, a considerable amount of the glaze sprayed from the spray device does not spray onto the tile surface, but instead sprays onto the belt 102 and adheres to the belt 102, resulting in a large amount of glaze being lost as material loss. A problem occurs.

Furthermore, it is necessary to clean and remove the glaze attached to the belt 102 at regular intervals, but this requires the conveyance device and spray device to be temporarily stopped, which reduces the operating rate of the device. This results in a decrease in productivity.

This problem also occurs when a mesh belt is used as the conveyance means.

(Means for Solving the Problems) The present invention has been made to solve the above problems, and its gist is that the planar shape is rectangular, a frame is arranged at the edge, The purpose is to use a shelf with a plurality of support bars stretched between the frames at predetermined intervals, and to send the shelf with tiles lined up on the shelf by a predetermined feeding means.

(Function) As mentioned above, when tiles are conveyed using a cord-like belt, etc., it is necessary to keep the tiles a certain distance apart from each other in the front and rear or left and right to avoid interference between the left and right tiles or the front and rear tiles during conveyance. However, when the tiles are transported using shelves as in the present invention, the tiles can be transported in a state where they are lined up left and right and front and back without gaps. In this case, almost all of the glaze sprayed from above by the spray device is sprayed onto the tile surface.
This greatly reduces glaze material loss.

Moreover, when transporting tiles using shelves,
Even if the glaze passes between the tiles and escapes downward, the amount of the glaze adhering to the shelf can be suppressed to a small amount.

As mentioned above, when conveying tiles using a cord-shaped belt, etc., the belt sways or sways, so it is necessary to convey the tiles while holding them in a stable position, so such a cord-shaped belt is not used. It is necessary to arrange the tiles closely, and in this case, a large amount of the glaze that has leaked downward between the tiles will adhere to the cord-shaped belt, resulting in material loss. In order for the shelf of the present invention to support tiles in a stable posture, it is possible to provide a large gap between the support bars, and in this case, the space between the tiles can be extended downwardly. Most of the glaze that has been added to the glaze passes between the support bars and goes down the shelf, and does not stick to the support bars. The glaze that has passed between the support bars can be recovered and reused, resulting in less loss of glaze.

The present invention also has the following features. In other words, since the shelf itself can be freely taken out from the conveyance line, it is easy to clean and remove the glaze that has adhered to the shelf, and during cleaning,
Since there is no need to stop the spray device, conveyance device, etc., the device operating rate can be increased, thereby contributing to improved productivity.

Further, according to the present invention, when stacking tiles, the tiles can be stacked together on shelves without having to be relocated.

When tiles are conveyed using the aforementioned conveyor belt or the like, it is necessary to take them out from the conveyor belt and transfer them onto a separate predetermined table when stacking the tiles. The shelf can be used as it is as a stand for stacking, and no special work is required to transfer the tiles. In addition, in the present invention, it is also possible to transport tiles in a stacked state by stacking shelves, thereby simplifying the work in the tile manufacturing line and saving labor.

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

In FIGS. 1 to 3, reference numeral 10 indicates an example of a shelf used in the present invention. This shelf 1
0 is made of metal (aluminum),
A frame 12 having a rectangular planar shape and arranged on both left and right edges, a plurality of plate-shaped support bars 14 stretched between these frames 12, and a frame extending through these support bars 14. 12 and a connecting rod 16 arranged in the same direction as the main elements. As shown in detail in FIG. 2, the frame 12 is made of a channel material having a U-shaped cross section, having a top plate part 18, a bottom plate part 20, and a hanging wall part 22. 20, a plurality of rectangular reinforcing pieces 24 are inserted and arranged in the recess surrounded by the hanging wall portion 22. Further, a plurality of ventilation holes 26 are formed in the hanging wall portion 22, into which a fitting convex portion 28 formed at the end of the support bar 14 is inserted and fixed by welding.

As shown in FIG. 2, a round hole 30 is formed in each of the support bars 14 arranged parallel to each other in the left-right direction that connects the frame 12, and a round rod (connecting rod) 16 is inserted through the hole 30. There is. The connecting rod 16 is welded to the support bar 14, and each support bar 14 is connected and reinforced in the front-rear direction by the connecting rod 16.

In this example, as shown in FIG. 4, the frame 12
The vertical height of the frame 12 is higher than the height of the support bar 14, and the support bar 14 is arranged at the upper and lower middle part of the frame 12, and the upper and lower ends of the frame 12 are respectively higher than the upper and lower ends of the support bar 14. It is made to protrude upward or downward by a certain dimension.

The shelf 10 of this example is configured with the following dimensional relationship. That is, the frame 12 and the support bar 14 have lengths of 1000 mm and 1500 mm, respectively, and the support bar 1
The arrangement interval of 4 is 75mm, so for example, 150×
Tiles of any size such as 150 mm, 100 x 200 mm, 200 x 200 mm, 300 x 300 mm, etc. can be placed thereon, and each support bar 14 is constructed so as to be almost completely hidden under the tile when these tiles are placed. has been done.

By using such a shelf 10, tiles can be transported in a state where they are lined up without gaps.
That is, for example, as shown in FIG. 5, the tiles are arranged without gaps on a shelf 10, and the frames 12 at both ends of the shelf 10 are placed on the feed rollers 32 and moved, so that the tiles are continuously conveyed. can do. In this case, each support bar 14 is almost completely hidden under the tile, and while the tile is transported using such a shelf 10, a slurry glaze is applied by a spray device 34 as shown in the figure. When sprayed/applied onto the tile surface, the glaze sprayed downward is efficiently sprayed onto the tile surface. That is, the amount of glaze that escapes downward through the gaps between the tiles is extremely small, and most of the glaze that escapes downward through the gaps between the tiles passes through between the support bars 14 as is. The amount of glaze that is lost by adhering to the support bars 14 is greatly reduced compared to conventional belt conveyance. Incidentally, in the case of the conveyance method using the above-mentioned cord-shaped belt, approximately 30% of the glaze is lost as material loss, whereas when the tiles are conveyed according to this example, the loss of glaze is 1/1 of that of the conventional method. It will be about 3.

In addition, since the glaze does not adhere to the shelf 10 as a tile conveying means, the frequency of cleaning the shelf 10 is reduced, and since the shelf 10 can be taken out from the conveyance line when cleaning is performed, cleaning is possible. The work can be done easily and there is no need to stop the conveyance line during the work.

In addition to the above, in this example, the height of the frame 12 is higher than the height of the support bar 14, and since the shelf 10 has a form in which both the upper and lower ends protrude beyond the upper and lower ends of the support bar 14, the tiles can be shelf 10
They can be stacked as they are, which has the effect of simplifying the work on the tile manufacturing line.

Although the embodiments of the present invention have been described in detail above, the present invention can be implemented in other embodiments.

For example, in the shelf 10 of the above example, the support bar 14
Although the support bar is made of a plate-shaped member, it is also possible to make the support bar of a round bar, square bar, or other shaped member, and the number of such support bars,
It is also possible to change the arrangement interval, dimensions, etc. as appropriate.

Furthermore, the present invention can be modified such that the support bars can be arranged in a lattice pattern, the frame can be arranged around the entire circumference, the shape of the frame can be different from the above example, and a chain or the like can be used as a means for feeding the shelves. It is possible to implement the present invention with various modifications without departing from the spirit thereof.

(Effects of the Invention) As described in detail above, according to the present invention, tiles can be transported in a state where they are lined up without gaps. As a result, the glaze sprayed by the spray device can be efficiently sprayed onto the tile surface, reducing glaze loss, and the glaze adhering to the shelf used as a transportation means can be easily cleaned and removed. The operating rate of the device can be increased without stopping the conveyance line during cleaning.

Further, according to the present invention, tiles can be stacked on shelves without being transferred, and various excellent effects such as simplifying work on a tile manufacturing line are produced.
