That is, after the first tile piece is received by the fixed stopper 19, the movable stopper 20 is immediately extended to receive the second tile piece,
Next, the movable stopper 21 is projected to receive the third tile piece to form a vertical joint.

Further, the joint adjustment piece 22 is positioned on one side of each tile received by the stopper, and the tile pieces are brought closer to the partition wall 24 side from the side to evenly adjust the horizontal joints. To explain the operating mechanism of this joint adjustment piece 22, the lower mounting plate of the adjustment piece 22 is pivotally supported on the machine base by a pivot 38, and the fixing rod attached to the mounting plate is connected to the operating rod 39, and the air cylinder 40 By the operation of , the fixed rod is pushed laterally through the operating rod,
8 as a fulcrum, the upper end of the adjustment piece 22 is rotated laterally to push the side of the tile piece. This joint adjustment piece 22 is normally stored in the recess 41 of the partition wall 24 so as not to interfere with the progress of the tile pieces.

In the figure, E is a backing paper storage device of an automatic backing device, and a storage body 43 stores small backing paper 42 of arbitrary shape only at the corner aggregation part a and outside b of a plurality of tile pieces.
The lower part of the laminated backing paper is held in association with the tip receiving part of the push-up rod 44, and the opening of the storage body 43 is provided with a light emitter and a light receiver (not shown) in association with each other. When the top backing paper is taken out, the storage backing paper is pushed up by one sheet. F is a backing paper adsorption device that adsorbs a set of backing papers from the storage device, transports them to the temporary adhesion position of the alignment and transfer device, and temporarily attaches them; G is an adhesion device that attaches water or glue to the back side of the backing papers; H is a tile suction device that adsorbs the temporarily pasted tiles and transports them to the final pasting table.On the final pasting table, another suction device (not shown) heats and presses the tiles to perform the final pasting, and then transports them to the carry-out conveyor. do.

Since the present invention has the above-described configuration, the transfer box 1 in which mosaic tiles are stacked and stored in multiple sets in advance by combining them in contact with each other is placed on the transfer device A, transferred to the suction transfer device B, and stopped at a predetermined position X. Then, the suction box support 7 is lowered by the air cylinder 5 of the suction transfer device B, and the suction port 10 of the suction box is brought into contact with the tile piece located at the top of the transfer box 1, and then the tile is removed by the suction force of the air. The pieces are held by suction and the suction box support 7 is raised by the operation of the air cylinder 5. At the time of the ascent, the suction boxes 9 on both sides are opened laterally to separate the tile pieces laterally, and then the air cylinders 13 are used to adsorb and transfer them. The apparatus B is moved laterally along the rail, stopped and lowered at a predetermined position Y on the belt of the alignment and transfer apparatus C, and the suction force is released and the tile piece is placed on the conveyor belt 17.

Next, the tile pieces are transferred by the conveyor belt 17 of the alignment and transfer device C, and temporarily held on the receiving plate 29 of the standby device D, and the temporary adhesion of the backing paper is completed at the temporary adhesion position to the preceding set of tile pieces. Then, the receiving table 29 is raised to transfer the next set of tile pieces, and the tiles that were in vertical contact due to the speed difference between belts 17 and 18 are removed. The first tile piece is received by the fixed stopper 19 which separates the pieces and is positioned in the tile path at the temporary attachment position of the rear belt 18, and the movable stoppers 20 and 21 receive the succeeding tile pieces in order and move the tiles vertically. Form a certain joint.
After a set of tile pieces is received by a stopper, it is pushed from the side with a joint adjustment piece 22 to adjust the horizontal joints. Then, on the tile piece whose vertical and horizontal joints are aligned on the belt at the temporary pasting position Z, the backing paper taken out from the backing paper storage device E by the backing paper adsorption device F is attached with water etc. by the adhesion device G. A mosaic tile is formed by temporarily pasting and connecting the tile pieces, and this mosaic tile is sucked by a tile suction device H and carried to a final pasting stand, after which it is finally pasted and then transported out.

Therefore, when temporary pasting of backing paper is performed on one set of tile pieces at the backing paper temporary pasting position Z, the next set of tile pieces is sent to the standby device by the conveyor belt 17, and then the next set of tile pieces The sets of tile pieces are moved from the transfer box 1 to the alignment transfer device C by the suction transfer device B, and are operated in a correlated manner according to a preset program. When the transfer box 1 is empty after all the tile pieces have been suction-transferred, it is pushed out by the air cylinder 14, and the transfer device A moves to move the next transfer box to the suction-transfer position, and the tile pieces are placed on the back side in the same manner as described above. It is automatically supplied to the pasting device.

〔Effect of the invention〕

According to this invention, a transfer box containing stacked tile pieces assembled without joints is placed on a transfer device at regular intervals, and is intermittently transferred to a suction transfer device. The tile pieces are automatically picked up one set at a time, and the tile rows are separated horizontally to form horizontal joints, and then transported to the alignment and transfer device, which also separates the multiple rows of tile pieces in the vertical direction. The tile is then received by a stopper at the temporary pasting position of the backing device to form vertical joints, and the vertical and horizontal joints between each tile piece can be automatically adjusted and supplied. Moreover, if a joint adjustment piece is provided, horizontal joints can be adjusted and supplied accurately.

Therefore, the process of supplying tile pieces with joints to the backing device can be automated without requiring any manual labor, and the feeding speed can be faster than that by hand, so the feeding efficiency can be significantly increased. By combining them, it is possible to completely automate the process from forming the joints of the tile pieces to supplying them and pasting the backing paper, and it is possible to improve productivity.
