Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device that grips and conveys cut sides of extrusion-molded tiles for splitting into two.

FIG. 1 shows the shape of a tile 1 for splitting into two. This tile for splitting into two parts 1 is made by cutting a continuously extruded molded body into predetermined dimensions.
After drying, glaze is applied to the upper and lower surfaces 1a and 1b,
Obtained by firing. This halving tile 1 is divided vertically into two to obtain two product tiles 2 as shown in FIG. 2. 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, and 1e and 1f are cut side surfaces.

By the way, the conventional glazing method for producing the tile 1 for splitting into two is as shown in FIG. The glaze is applied by spraying using a spray applicator 6 located above. However, in this glazing method, the glaze sprayed between each tile 1 dries and adheres to the upper surface of the flat belt 5. For this reason, there were disadvantages in that the flatness of the belt 5 was impaired, the amount of glaze used was increased, and the upper and lower surfaces (glazed surfaces) of the tiles were stained or damaged. Furthermore, it is necessary to stop the production line at predetermined intervals and replace the flat belt 5, or to peel off and remove the glaze adhered to the flat belt 5, resulting in a reduction in productivity. This was a fatal drawback, especially in production lines where full automation was established.

The present invention has been developed to improve and eliminate the above-mentioned drawbacks of the conventional technology, and by crimp-clamping the cut sides of tiles for halving and transporting them, it is unnecessary to install a flat belt in the glazing section. It is an object of the present invention to provide a conveying device of this type that is capable of recovering glaze sprayed between tiles for splitting into two parts.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

FIG. 4 is a plan view showing the entire conveying device 7 according to the present invention. In the figure, 8A and 8B are endless conveyor belts (V-belts) arranged on both sides of the conveyance path of the tile 1 for splitting into two. The conveyor belts 8A and 8B are wound around drive or support pulleys 9 and 10 at both ends with the belt surfaces in a horizontal state (so-called vertical installation type). The intermediate portion of the belt located above each belt 8A, 8B is connected to two guide pulleys 11, 12 installed at an angle, and a linear guide disposed between the guide pulleys 11, 12. Both belts 8 in the section of the guide rail 13 are supported by the rail 13.
A and 8B are twisted from a horizontal state to a vertical state. The guide rails 13, 13 can each be moved in the left-right direction in FIG. 6 by adjusting the support frames 14, 14, and the gap between the guide rails 13, 13 can be adjusted as desired. . A strip 15 made of soft rubber and having a large number of small protrusions erected thereon is attached to the surface side of the conveyor belts 8A, 8B. The above-mentioned small protrusion is located in the section of the guide rail 13 in the conveying direction, as shown in FIGS. Three small protrusions 16a, 16b, 16c installed in the direction, and two small protrusions 17a, 17b installed in the vertical direction that contact the cut side surfaces 1e, 1d of the split tile 1.
It becomes more. The small protrusions 17a and 17b are arranged above and below the horizontal small protrusion 16b. These five small protrusions constitute one pattern P, and a large number of such patterns P are provided on the conveyor belts 8A and 8B. In addition, the number and arrangement of each small protrusion constituting this pattern P are as follows:
It is not limited to what is described above.

In FIG. 4, 18 is a chute for carrying in (it may be a flat belt), 19 is a support frame that adjusts the height of the outlet side of the chute 18 according to the thickness of the tile 1 for halving, and 20 is for carrying out. The flat belt 21 is a glaze spray coating device installed above the conveying device 7 in the section of the guide rail 13.

Next, the operation mode of the conveyance device 7 configured as described above will be explained.

The tile 1 for halving carried in by the chute 18 has its belt surface twisted from a horizontal state to a vertical state, and at the same time the conveyor belt 8A, whose interval is narrowed,
The cut side surfaces 1e and 1f are crimped and clamped by 8B. The clamping state is as shown in FIGS. 4, 6, and 7, and each conveyor belt 8A, 8B
A plurality of appropriate horizontal projections 16a to 16c partially enter the through hole 3 of the halving tile 1 to prevent it from falling. In addition, the remaining horizontal small protrusions 16a to 16
c, and the small projections 17a and 17b in the vertical direction elastically contact the cut side surfaces 1e and 1f of the tile 1 and clamp them. In this way, the tile 1 held between the cut sides 1e and 1f is conveyed along the section of the guide rail 13, and as it passes through the section,
Spray coating device 21 placed above the middle part
Glaze is applied to the upper surface 1a by. In other words,
The section of the guide rail 13 is a glazed section.
The glaze sprayed between each tile 1 is applied to the conveyor belts 8A and 8B in the section of the guide rail 13.
It is possible to collect the waste by disposing a saucer or a funnel-shaped container below the gap. The glazed tiles 1 are released from the clamping force from the conveyor belts 8A, 8B at the end of the guide rail 13, and are then transferred to the flat conveyor belt 20 disposed below between the belts 8A, 8B. It is transferred and transported to a reversing device for the next process. Then, the upper and lower surfaces 1a and 1b of the tile 1 are reversed by this reversing device. After that, the above-mentioned transport device 7 and spray coating device 21
The glaze may be applied to the lower surface 1b of the tile in the same manner as described above.

If this is the case, the contact surfaces of each of the small protrusions 16a to 16c and 17a and 17b with the tile 1,
No glaze will stick to it. Moreover, since a plurality of horizontal small protrusions 16a to 16c fit into the through hole 3, stable support is possible.
In addition, the support of the tile 1 is the cut side surface 1 of the tile 1.
Since the tiles e and 1f are clamped together, they do not come into contact with the glazed surface (1a or 1b) of the tile 1, and the glazed surface is not stained or damaged. Furthermore, the glaze sprayed between the tiles 1 can be easily recovered.

In addition, the conveyor belts 8A and 8B of the conveyor device 7
Although a so-called vertically installed type belt was described, a so-called horizontally installed type belt in which the belt surface is vertical in the same manner as in the section of the guide rail 13 may also be used.

As explained above, in the present invention, by clamping and conveying the cut side of the tile for halving, it is unnecessary to install a flat belt in the glazing section, and the glaze sprayed between the tile for halving can be removed. It is possible to recover. Therefore, in conventional conveying devices of this type that have a flat belt in the glazing section, the glaze is also applied to the flat belt and dries and hardens.
The flatness of the flat belt may be lost, and the glazed surface of the tile that has been painted in half may become stained or damaged by the glaze that has dried and adhered to the flat belt. The present invention does not have the disadvantage of having to be cleaned and replaced.
