Abstract

(57) [Summary] [Purpose] To prevent damages that occur on the lower surface side of tiles at the transfer part between the conveyor belts. [Constitution] The trailing end portion of the preceding conveyor belt 13 is made to have an upward slope, and the starting end portion of the succeeding conveyor belt 17 is made to have a gentler slope, that is, a downward slope or a horizontal slope.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a delivery part between conveyor belts in a tile conveying device, and is particularly installed in a production line of divided tiles or the like.

[0002]

[Prior Art]

 In the tile production line, the tile base is transported by a conveyor, and the glazing and baking processes are used.

Conventionally, in this type of conveyer conveyor, a continuous transfer belt transfer unit 1 has a slight gap between a preceding conveyer belt 2 and a succeeding conveyer belt 3 as shown in FIG. The conveyor belts 2 and 3 are arranged continuously so that the horizontal levels of the conveying surfaces of the conveyor belts 2 and 3 are substantially the same.

[0004]

[Problems to be solved by the device]

 However, in the conventional delivery section 1 of the conveyor belts shown in FIG. 3, the conveyor surfaces of the conveyor belts 2 and 3 cannot be installed without a gap, so that, for example, the horizontal level of the conveyor belt 2 on the leading side is the trailing side. If it is installed higher than the horizontal level of the conveyor belt 3, the tip lower surface side of the tile 4 may hit the starting end side of the conveyor belt 2 in the traveling direction, and the tip lower surface side of the tile 4 may be damaged.

On the contrary, if the horizontal level of the leading side conveyor belt 2 is lower than the horizontal level of the trailing side conveyor belt 3, the tile 4 is temporarily transferred to the trailing side conveyor belt 3 and then the tile 4 moves. The lower surface of the rear end of No. 4 may fall due to the level difference between the conveyor belts 2 and 3 and hit the conveyor belt 2 to be damaged. In particular, so-called divided tiles are transported sideways until they are separated, and since the part that becomes the tile surface is the side surface, the above-mentioned defects cause defects in the tile surface and result in defective products.

[0006]

[Means for Solving the Problems]

 In the tile transfer device according to the present invention, at the transfer part between the first transfer belt and the second transfer belt, which is provided to transfer tiles, the end part of the first transfer belt has an upward slope, The starting end of the second conveyor belt has a gentler slope than the ascending slope. Here, the phrase “a gentle slope” of the second conveyor belt means that a horizontal slope and a downward slope are included in addition to the ascent slope lower than the ascent slope.

[0007]

[Action]

 Since the rear end of the first conveyor belt has a climbing slope, approximately half of the conveyed tiles are slightly lifted and fall toward the second conveyor belt due to the weight of the tile. The tiles are moved so as not to be damaged, and the lower surface side of the tip end of the tile does not hit the second conveyor belt to be damaged. Further, since the inclination of the second conveyor belt is also gentler than the inclination of the first conveyor belt, the lower surface of the rear end of the tile will not fall onto the first conveyor belt and be damaged.

【Example】

 Hereinafter, an embodiment of the tile transfer device according to the present invention will be described with reference to the drawings. FIG. 1 is a side view showing an embodiment of a tile transfer device according to the present invention, showing a delivery part of a transfer belt, and FIG. 2 is a side view showing another embodiment. The tiles described in the following embodiments are so-called divided tiles 6 as shown in FIG. 4, and the divided tiles 6 include a protrusion 7 at the front end, a recess 8 at the rear end, and a flat plate portion at the center. 9 are formed so as to extend in the longitudinal direction, respectively, and notches 10 for splitting are provided at the central positions of the projecting portion 7 and the concave portion 8 along the longitudinal direction. After the glazing process and firing process (not shown) are completed, this tile base material becomes the tile pieces 12 that are vertically divided by the notches 10 and 11 (see FIG. 5).

In the delivery section 15 of the conveyor belts 13 and 14 shown in FIG. 1, the terminal end portion 16 of the conveyor belt 13 on the leading side has an upward slope. Pressing rollers 18 and 18 are installed at two points on both sides of the conveyor belt 13 at the starting point 17 of the climbing slope in order to prevent the conveyor belt 13 from being loosened.

On the other hand, the starting end portion 19 of the conveying belt 14 on the trailing side has a downward slope. At the end point 20 of the downward slope, pressing rollers 21 and 21 are installed like the pressing rollers 17 and 17.

The position of the starting point 17 of the conveyor belt 13 and the installation position of the ending point of the conveyor belt 14 are optimized depending on, for example, the size of the tile to be conveyed, but it is preferably at least longer than the length of the tile. .

Then, when the tile transporting device having the above-described configuration is used to transport the divided tiles 6, the divided tiles 6 climb up from the terminal end portion 16 of the transport belt 13 with an inclination, and about a half portion thereof is transported. The divided tile 6 is transferred from the belt 13 so that the divided tile 6 falls from the belt 13 to the side of the conveyor belt 14 due to its own weight. Therefore, the lower surface of the tip end of the divided tile 6 does not hit the conveyor belt 14 and be damaged. Further, once it is transferred to the conveyor belt 14 side, the divided tiles 6 become stable on the downwardly-conveyed conveyor belt 14, so that the divided tiles 6 do not fall onto the conveyor belt 13 side again, and the rear end of the divided tile 6 is prevented. There is no risk of damage to the lower surface.

FIG. 2 shows another embodiment of the tile transfer device according to the present invention, in which the transfer belt 23 on the trailing side is in a horizontal state. Other configurations are the same as those in FIG. Compared to FIG. 1, the transfer unit 24 has a small degree of rotation when the tiles are transferred, and thus is suitable for carrying long tiles, for example.

In addition to the above-described embodiment, it is needless to say that the gradient of the succeeding conveyor belt can be made gentler than the gradient of the preceding conveyor belt.

[Effect of the device]

 As described above, according to the present invention, the lower surface side of the tile is not damaged at the transfer portion between the conveyor belts. Therefore, particularly when the divided tiles are conveyed, the tile surface is not damaged, and the occurrence of defects can be suppressed.
