Description

[Detailed description of the invention] The present invention is equipped with an endless carry-in belt and an endless carry-out belt, and inverts the article so that the upper and lower surfaces of the article are reversed in the transfer area from the carry-in belt to the carry-out belt. It is related to the device.

Here, items that require reversal are items such as tiles, bricks, roof tiles, etc. that require reversing the top and bottom sides (the front and back sides are the same) and applying some kind of processing to each side. be. The following will be described based on an example in which glazing is applied to the upper and lower surfaces of a tile for splitting into two parts.

FIG. 1 shows the shape of a tile 1 for splitting into two. This tile 1 for splitting into two parts is made by cutting a continuously extruded molded body into predetermined dimensions, and then glazing the top and bottom surfaces 1a and 1b.
Obtained by firing. The tile 1 for splitting into two is divided into two vertically to obtain two product tiles 2 shown in FIG. 2. The upper and lower surfaces 1a and 1b of the above-mentioned halving tile 1 serve as the tile surfaces of the product tile 2, respectively. Reference numeral 3 denotes a through hole provided in the halving tile 1 to form the sole 4 of the product tile 2.
In Fig. 1, 1c and 1d are extruded side surfaces, 1
e and 1f are cut sides.

When the upper and lower surfaces 1a and 1b of the tile for splitting into two 1 are to be glazed, one of the upper and lower surfaces 1a and 1b is first glazed, and this is reversed and the remaining surfaces are glazed. A conventional reversing conveyance device is as shown in FIG. This reversing conveyance device 5 includes a carry-in belt 6, a carry-out belt 7, and a round belt 8.
It has three belts. The carrying belt 6 is
The belt is wrapped around a horizontal type belt pulley 9 placed on the carry-in side and a vertical type belt pulley 10 placed on the carry-out side, and twisted so that the surface of the belt changes from a horizontal state to a vertical state. Further, the carry-out belt 7 is wrapped around a vertical type belt pulley 11 placed on the carry-in side and a horizontal type belt pulley 12 placed on the carry-out side.
The surface of the belt is twisted from vertical to horizontal. The carry-in belt 6 and the carry-out belt 7 are arranged so that they partially overlap with a predetermined gap. The round belt 8 is wound around a pulley 13 mounted on the rotating shaft of the belt pulley 9 and a pulley 14 mounted on the rotating shaft of the belt pulley 12, and passes between the carry-in belt 6 and the carry-out belt 7. It's on.

Tiles 1 for splitting into two placed on the carrying belt 6
As the carry-in belt 6 advances, the attitude is raised from a horizontal state to a vertical state one after another. As the tile 1 assumes its posture, its side surface comes into contact with the round belt 8 and is supported by this.
Then, due to the force of being conveyed, the article falls down from the vertical position toward the conveying belt 7 side, transfers to the belt 7, and is conveyed to the next process. The tile 1 is located in the above-mentioned transfer area from the carry-in belt 6 to the carry-out belt 7, and the contact surface with the carry-in belt 6 becomes the upper surface when placed on the carry-out belt 7, and the tile 1 is reversed. It is.

By the way, in the delivery area of the tile 1 mentioned above, the round belt 8 is connected to the tile 1 as shown in FIG.
It is important to support the central part of the tile 1 by standing vertically at the center of the gap W between the carry-in belt 6 and the carry-out belt 7. However, in reality, as the weight of the succeeding tile 1 is added to the round belt 8, the round belt 8 is bent and, as shown in FIG. 5, is supported eccentrically with respect to the tile 1 in most cases. . For this reason,
Part of the side surface and part of the glaze surface of tile 1 were sometimes damaged. Also, if the thickness t of the tile 1 changes, the gap W between the carry-in belt 6 and the carry-out belt 7
It is necessary to change the However, when the gap W is changed, the center line connecting belt pulleys 9 and 10 and the center line connecting belt pulleys 11 and 12,
The center lines connecting pulleys 13 and 14 are no longer parallel to each other. For this reason, the loading and unloading belt 6,
7 have different distances from the round belt 8, especially the belt pulley 10 of the carry-in belt 6.
In the vicinity, the amount of eccentricity of the round belt 8 had become extreme due to the addition of the aforementioned eccentricity factor. As a result, the degree of damage to tile 1 became severe, and tile 1 sometimes fell off. For these reasons, in the conventional reversing conveyance device 5, the gap W between the carry-in belt 6 and the carry-out belt 7 is usually kept constant, and it cannot be used for tiles having different thicknesses t.

The present invention improves and eliminates the above-mentioned drawbacks of the conventional technology, and includes a portion where the carry-in belt and the carry-out belt overlap with a variable predetermined gap,
By providing continuous uneven article support members on the lower side edges of both belts, it is possible to realize reversal conveyance of articles in a stable and reliable supported state, and also to prevent articles of different sizes from being conveyed. It is an object of the present invention to provide a reversing conveyance device for articles, which can be conveyed even when the articles are conveyed.

The configuration of the present invention will be described below with reference to the drawings based on an embodiment of an apparatus for transporting tiles for halving with their upper and lower surfaces reversed.
Note that the same reference numerals as in the conventional case represent the same members.

FIG. 6 is a schematic plan view showing the entire embodiment device 15 according to the present invention. The tension structure of the carry-in belt 6 and the carry-out belt 7 is the same as in the conventional case.
In this embodiment, as shown in an enlarged view in FIG. 7, a V-shaped cross section is provided at the lower side edges of both belts 6 and 7 where the carry-in belt 6 and the carry-out belt 7 overlap. The support members 16 of the article are attached in succession. The vertical belt pulleys 10 and 11 of both belts 6 and 7 are made movable as shown by the arrows in FIG. I have to. Further, by pressing the entrance side of the carry-in belt 6 wrapped around the belt pulley 10 from the inside with a roller 17, the carry-in belt 6 at this portion is inclined toward the carry-out belt 7 side. Note that this roller 17 is not necessarily necessary. Moreover, the roller 17 may be constructed in place of a plate member.

Reversing conveyance device 15 for articles configured in this way
If so, the surface of the carry-in belt 6 is sequentially twisted from a horizontal state to a vertical state, so that the carry-in belt 6
The tiles 1 placed in a horizontal state are sequentially raised to a vertical state. As the posture occurs, the tile 1 comes into contact with the support member 16 with its side surface and is supported by the support member 16. Then, the roller 17
It is pushed out toward the carry-out belt 7 side and supported by the supporting member 16 of the opposing carry-out belt 7. That is, regarding the carry-in belt 6 and the carry-out belt 7,
Tile 1 is transferred. At this time, the surface of the tile 1 that was in contact with the carry-in belt 6 becomes a non-contact surface on the carry-out belt 7 side, and when the carry-out belt 7 becomes horizontal, the non-contact surface becomes the upper surface.
That is, the upper and lower surfaces 1a and 1b of the tile 1 are reversed. By inverting and transporting the tile 1 in this way, it is possible to glaze the upper and lower surfaces 1a and 1b of the tile 1 before and after the device 15.

If the thickness of the tile for splitting into two 1 changes, the gap between the carry-in belt 6 and the carry-out belt 7 may be adjusted by moving the belt pulleys 10 and 11 as shown by the arrows in FIG. In this device 15, the vertically erected tile 1 is supported by the support member 16, so even if the gap between the belts 6 and 7 is changed, there will be no problem in supporting the tile 1. This enables reliable and stable support.

Note that the supporting members 16 for the article are not limited to those having the above-mentioned shape, and for example, members having a U-shaped cross section or rod-shaped members may be attached at predetermined intervals. Alternatively, a material may be used that is flexible in the transport direction and has high rigidity in the vertical direction at the portion where the carry-in belt 6 and the carry-out belt 7 overlap, so that the belt has a U-shaped cross section. Further, this reversing and conveying device 15 can be applied not only to the above-mentioned tile 1 for splitting into two, but also to articles that require reversing, such as bricks and roof tiles, and can be used in a wide range of applications. Furthermore, if necessary, by making the carry-in belt 6 slope downward toward the carry-out side and the carry-out belt 7 slope upward towards the carry-out side, the support members 16 of both belts 6 and 7 may come into contact with each other. At the same time, the support member 16 of the carry-out belt 7 may scoop up and receive the tile 1 supported by the support member 16 of the carry-in belt 6 from below.

Also, if the thickness of tile 1 becomes smaller,
There is a possibility that the supporting members 16 of both belts 6 and 7 may interfere with each other. In such a case, both belts 6,
The support members 16 of both belts 6 and 7 may be engaged with each other by adjusting the conveyance speed and conveyance timing of belt 7. Alternatively, the rigidity of the support member 16 of one of the belts may be reduced so that the support members 16 of both belts are plastically deformed when they interfere with each other.

As explained above, in the present invention, in the part where the carry-in belt and the carry-out belt overlap with a variable predetermined gap, the lower side edges of both belts are provided with continuous unevenness. Since the article supporting members are respectively provided, when the articles are transferred from the carry-in belt to the carry-out belt, the articles in the upright state can be reliably supported from below by the support members, and stable support can be obtained. Furthermore, since the article is supported as described above, even if the thickness of the article changes, it is possible to adjust the gap between the carry-in belt and the carry-out belt and reverse conveyance. In short, the apparatus of the present invention is capable of stable and reliable reversal conveyance even for articles of different sizes. Therefore,
Conventional reversing conveyance devices supported articles in eccentric positions, which caused accidents such as articles falling off or parts of articles being damaged, but the device of the present invention eliminates these problems. It doesn't exist at all.
