Information board 96
Since it has a bearing on the ground surface with the pallet truck 90, it does not prevent the pallet truck 90 from moving up and down.

The tile transfer device 1, which includes the above-mentioned tile fabric conveyor 10 and the like, transfers the tile fabric W transported from the tile forming INK by the tile fabric conveyor 10 onto the pallet truck 90 as described below. As shown in Fig. 5, the pallet P is a rectangular body on which tile fabrics W can be placed horizontally in 5 x 3 rows. It is equipped with a raw tile floor support Po of a shape suitable for.

When the tile fabric conveyor 10 conveys the tile fabric W to its terminal end, the tile fabric suction transfer member 8 moves from the original position shown in FIG.
0 is lowered, and the suction pads 84 in two directions come into close contact with the raw tile floor W. The suction pad 84 suctions and holds the raw tile floor W by the negative pressure of the blower 77.

Then, while holding the five pieces of tile fabric W from two directions, the tile fabric suction and transfer member 80 rises, and the traveling cart 60 moves to a predetermined position on the pallet P waiting at the pallet standby position of the pallet conveyor 30, for example. After traveling to the first row, it stops. Then, the tile material suction and transfer member 80 descends and places the tile material W on the raw tile material receiver Po in the first row of the pallet P.

The suction pad 84 releases the suction of the tile cloth W when the negative pressure of the suction pad 84 is eliminated by the suction switching valve 78 attached to the top surface of the traveling carriage 60. Then, as the tile material suction and transfer member 80 rises, it returns to its original position above the tile material carrying conveyor 10 due to the travel of the traveling cart 60, and is in a state where a new tile material W is transferred. In this way, the tile fabrics are repeatedly placed on the pallet P, and when a predetermined number of tile fabrics W are placed on the pallet P, the pallet conveyor 30 transfers the pallet P to the pallet cart 90.
It is stored in the pallet storage shelf 92. In this way, palette P
When storage is completed, the pallet truck lifting lifter 100 raises or lowers the pallet truck 90, and the pallet storage shelf 9 on which the pallet P on which no tile material is placed is stored.
2 at a height suitable for the pallet conveyor 30 and then stopped. And the pallet bushing 107 is the pallet storage shelf 92
After the pallet P inside is pushed out to the pallet conveyor 30, the pallet conveyor 30 transports this pallet P to a pallet standby position. In this way, when the pallet P carrying the tile fabric W is stored in the pallet storage shelf 92 of the predetermined stage of the pallet truck 90, the pallet truck 90 on which the tile fabric W has been transferred is transported to the next process and a new one is placed. The pallet truck 90 enters the pallet truck lifter 100, and the tile material W is removed.
Repeat the transfer. Since replacing the pallet truck 90 takes more time than replacing the pallet P to the pallet conveyor 30, it may be necessary to stop conveying the tile fabrics on the tile fabric conveyor 10 during this time. Therefore, in order not to stop the conveyance of the tile fabric, the tile fabric W that has been conveyed during the idle time when the pallet truck 90 is replaced is placed on the pallet P at the pallet standby position and on the idle stage 20. Note that the new pallet truck 90 that enters the pallet truck lifter 100 does not have the pallet P loaded on one stage of the pallet storage shelf. This is because when replacing the pallet cart, the tile material W
This is to first store the pallet P which is placed in the pallet standby position.

The tile transfer device 1 described above consists of a pallet conveyor that horizontally transfers pallets and a pallet truck lifting/lowering lid that raises and lowers the pallet truck.Since the pallets are stored in the pallet truck, the number of components for each member is small and the number of complicated components is small. No drive mechanism required. Therefore, the device can be made smaller, so
It is possible to save installation space and reduce equipment investment costs.

In addition, multiple pieces of tile fabric can be automatically placed on a pallet in a flat position suitable for flat drying, and the pallet can be automatically stored in a pallet truck, reducing the work required to transfer tile fabric. This can be easily done without any manual intervention. Furthermore, in this example, since an idle stage for temporarily storing the tile fabric is provided, the tile fabric can be transferred without stopping the tile fabric transport from the tile forming machine, which improves the transfer efficiency. improves.

Effects of the Invention As described above in detail including the embodiments, the tile transfer device of the present invention can save space and can be installed without requiring expensive capital investment. Further, a large number of tiles can be stored in a flat state on a pallet truck without any manual intervention, and labor savings in the tile transfer work can be easily achieved.
