FIGS. 4 to 6 show the details of the gluing device 14. The glue discharging portion 49 is formed by forming a glue collecting portion 49 by a groove in the lengthwise direction and arranging small holes in the glue collecting portion 49. A rotatable glue pipe 36 which forms 35 and has a spiral groove 50 formed on the peripheral surface other than the glue reservoir 49, and a free roller 37 which opposes this are combined, and transmitted to the glue pipe 36. A motor 39 connected by a gear 38 is arranged in parallel. The glue pipe 36 was connected to a glue container 47 via a glue feeding hose 45 made of a flexible tube.
Then, these are stored in a dolly 41 having wheels 40,
The trolley 41 faces the pressure roller 15 and the photographic paper 2
The guide rail 42 extending along the traveling line of was movably installed.

Although various traveling drive mechanisms of the carriage 41 are conceivable, a rotary spiral rod 43 is provided along the guide rail 42, and a spiral receiving portion 44 provided on the carriage 41 side is engaged with the rotary spiral rod 43.
Although not shown, the rotary spiral rod 43 is rotationally driven by a motor.

Next, usage and operation will be described. The photographic paper 2 set in a roll on the roll feeder 1 is pulled out from the roll feeder 1, and the guide roller 4, the reverse rotation tension roller 13,
It is sequentially fed out through the guide roller 4, the gluing device 14, and the pressure bonding roller 15.

When passing through the gluing device 14, the glue discharged from the glue discharge portion 35 of the glue pipe 36 is applied to the upper surface of the glue pipe 36 opposite to the printing surface of the photograph and dried by the dry air pipe 19. In particular, since the back side of the photographic paper 2 has a vinyl surface, it is difficult to absorb water, while the postcard to be attached is liable to absorb water, and thus curling may occur unless proper drying is performed.

Further, spraying with the fog generator 46 may give a proper amount of moist air. The fog generator 46 is used when the photographic paper 2 is temporarily stopped during operation.
In such a case, the adhesiveness of the adhesive can be restored by applying an appropriate amount of moist air to the portion that has already been applied with the adhesive and is about to dry, by spraying with the mist generator 46.

On the other hand, at the inner bottom of the postcard paper box 20, the flip-up plate 25 vibrates by the eccentric cam 26, and the postcard paper 23 at the lowermost stage is placed above the bottommost postcard sheets stacked by the flip-up plate. Several postcards are placed in a slanted step so that the one on the rear edge goes out. On the contrary, the front end is a slanted step such that the lower one goes out to the outside, and the postcard paper 23 at the lowermost step is the most protruding at the front end.

Then, the front end of the lowermost postcard paper 23 is surely fed to the feeding roller device 24.
The sheet is sandwiched by 24a and passed to the driving roller 24b, and is sent by the driving roller 24b and discharged one by one. Moreover, the drive roller 24b of the delivery roller device 24
Is a position sensor that detects the photo position of photographic paper 2.
Since the synchronization is made at 30, the postcard paper 23 is sent out according to the photo position printed on the photographic paper 2, and the postcard paper 23 is attached to the photographic paper 2. In this case, the sensor 28 can detect the movement of the rear end of the lowermost postcard paper 23 sent by the sending roller device 24, and the synchronization can be made more reliable.

The photographic paper 2 thus pasted with the postcard paper 23 passes through the pressure roller 15 and is firmly glued and fixed. Then, the slitter 17 cuts and removes the side margins, and the head cutting rotary cutter 16 The head portion is cut by the guillotine type cutter 18, the remaining rear margin is cut and removed by the guillotine type cutter 18, and the product is collected in the product collection box 33.

Next, the movement of the gluing device 14 will be described. Although FIG. 7 is an explanatory view thereof, for example, a sensor 48 is provided between the reverse rotation tension roller 13 and the gluing device 14.

This sensor 48 detects a stop signal on the photographic paper 2 during normal operation. Then, the supply of the glue from the gluing device 14 is stopped at the stop signal position on the photographic paper 2.

No glue is applied to the photographic paper 2 after the stop signal, and the glue pipe 36 is rotated by the motor 39 so that the glue discharge portion 35 is directed upward to prevent the glue from dripping. Rotating spiral rod at the same time
43 is rotationally driven, and the gluing device 14 is moved along with the movement of the carriage 41.
Also moves to the right fixed position.

When the postcard paper 23 has been pasted up to the end of the glue-applied portion of the photographic paper 2 (stop signal position), the supply of the postcard paper 23 in the postcard paper box 20 is stopped, and at the same time the pressure roller is pressed. The drive roller for running the photographic paper 2 such as 15 also stops, and the photographic paper 2 also stops on the spot.

When the postcard paper 23 in the postcard paper box 20 is replaced with a new one and restarted by another signal, the drive rollers such as the pressure roller 15 rotate in the reverse direction and the stop signal position of the photo paper 2 is reached. Sends the photographic paper 2 back to the position of the glue discharge part 35 at the right fixed position of the gluing device 14. The reversely fed photographic paper 2 is fed toward the roll feeder 1 while being tensioned by the reversely rotating tension roller 13, and the reversely rotating tension roller 13 absorbs the excess.

While the supply of the postcard paper 23 from the drive roller such as the pressure roller 15 and the postcard paper box 20 is stopped, the carriage 41 and the gluing device 14 rotate the glue pipe 36 so that the glue discharge part 35 faces downward. , And photo paper 2
The adhesive is continuously supplied to the left fixed position while supplying the adhesive to the photographic paper 2.

When the gluing device 14 returns to the left fixed position (normal position), the photographic paper 2 starts to be driven, and at the same time, the postcard paper 23 in the postcard paper box 20 starts to be supplied to start the normal operation.

[0038]

As described above, in the photo postcard manufacturing apparatus of the present invention, it is possible to set the postcard paper on the gluing surface of the photographic paper in a reliable position, and to restart after the suspension. Even in the case, it is possible to start the gluing from the necessary position and prevent waste.
