6 and the application roller 51 rotate, and the pump 75
Is also energized, the adhesive of the tank 71 drops from the hose 72 to the rollers 55 and 56, and is transmitted to the coating roller 51.
Further, the pinch roller 53 is kept in a state of being separated from the coating roller 51. When the tile aligning pallet 11 reaches a predetermined position, the proximity switch 15 detects the roller 11d of the pallet 11, so a signal is output from the switch 15 and the motor 30 and the motor 31 are energized based on this signal. The rotation of the drive rollers 25A, 26A, 27A is started.

As the driving roller 25A rotates, the leading end of the roll-shaped tile connecting sheet 21 sandwiched between the driving roller 25A and the pinch roller 25D is guided by the guide plate 2.
The shaft 23 is fed downward along the shaft 9 and rotates. When the leading edge of the sheet 21 passes through the drive roller 26A and reaches a position close to the drive roller 27A, the leading edge is detected by the optical sensors 48A and 48B. Based on the output signals of the optical sensors 48A and 48B, the actuator 4

At the same time, the energization of the motor 30 is interrupted and the drive roller 25A is stopped, so that the rotation of the shaft 23 is stopped and the feeding operation of the leading end of the sheet 21 is temporarily interrupted. On the other hand, since the motor 31 continues to be energized, the sheet piece 21A cut into a predetermined width is driven by the drive roller 2
6A and 27A and the pinch rollers 26B and 27B continuously feed the downward direction, and the coating roller 51 and the pinch roller 53
In between. When the sheet piece 21A reaches the coating roller 51, a timer (not shown) operates the actuator 53F to move the pinch roller 53 to the coating roller 51.
The adhesive adhered to the surface of the roller 51 is applied to the lower surface of the sheet piece 21A. When the sheet piece 21A passes between the rollers 51 and 53, the pinch roller is separated from the coating roller 53 by the actuator 53F. The sheet piece 21A coated with the adhesive in this manner is further extended downward along the guide plate 59 by the application roller 51 and the pinch roller 53, and is pressed against the tile T on the pallet 11 by the pressure roller 61. 21A is attached to the surface of the tile T.

On the other hand, to the motor 30 whose energization is interrupted based on the signals of the optical sensors 48A and 48B, energization is resumed after a predetermined time set by a timer (not shown) has elapsed. As a result, the shaft 23 of the roll-shaped tile connecting sheet 21 that has stopped stops rotating, and the sheet 21 is fed downward by the drive rollers 25A, 26A, 27A and the pinch rollers 25B, 26B, 27B as described above. Then, when the tip ends are detected by the optical sensors 48A and 48B, the cutting means 40 cuts into a predetermined width and the motor 30 stops. By such a series of steps, a predetermined interval corresponding to the time set by the timer is formed between the preceding sheet piece 21A and the following sheet piece 21A. This space is the distance between the tiles T placed on the adjacent tile alignment pallets 11 on the rail 12.
It is set according to the interval.

According to the present embodiment, however, the tile-connecting sheet 21 wound into a roll is automatically cut into a predetermined width, and the cut sheet piece 21A is being conveyed by the chain belt 13 at a constant speed. The sheet pieces 21A are being transferred to the pallet 11 from above so that the sheet pieces 21A are being transferred without interruption.
It can be attached to the tile T placed on. Therefore, it is not necessary to transfer the pallet 11 intermittently, and the efficiency of the step of attaching the sheet piece 21A is significantly improved. Further, a roll-shaped tile connecting sheet 21, drive rollers 25A, 26A, 27A, pinch rollers 25B, 2
Since most of the necessary mechanisms such as 6B, 27B and the cutting means 40 are arranged above the rails, the space required for installing the device can be saved. Further, since the pinch roller 53 arranged so as to face the coating roller 51 can be selectively held in the operating position where it abuts the coating roller 51 and the non-operating position where it is separated from the coating roller 51, both tile connecting sheets 21A can be held. Before reaching between the rollers 51 and 53 and after passing between the rollers 51 and 53, the pinch roller 53 is separated from the coating roller 51, so that the pinch roller 5
It is possible to prevent the adhesive from adhering to the surface of No. 3 and the upper surface of the tile connecting sheet 21A. Therefore, it is possible to prevent the sheet 21A attached to the tile T from being wrinkled or the attachment position being displaced.
