There is a need to.

Furthermore, the viscosity of this UV curable resin liquid changes with temperature,
This will prevent uniform application, so especially when placing the part where the UV curable resin liquid is applied and the UV irradiation part to be cured in close proximity, make sure that it is not affected by heat from the UV irradiation part. At the same time, if dust adheres to the UV curable resin liquid, the quality of the ID card will be impaired, so it is necessary to configure the device to prevent dust from adhering.

This invention has been made in view of the above points, and provides a protective layer forming device for ID cards that is small and capable of high-speed processing, and that is capable of coating and curing UV curable resin in an appropriate environment. The purpose is to

[Means for Solving the Problems] In order to achieve the above object, the ID card protective layer forming apparatus of the present invention includes a card conveyance path for conveying a card-shaped photosensitive material inside the apparatus main body.

Note that depending on the type of ID card I, it may be sufficient to just take a data image.

This photosensitive material 2 is cut in advance to the size of an ID card I, and as shown in FIG. 4, writing 112b is formed on one side of the base synthetic resin support 2a, and this writing Fi2b is It corresponds to conventional note paper and allows you to freely write on it with a pencil or pen.

Further, a photosensitive emulsion layer 2c is formed on the other side of the support 2a, and a person image and a data image are formed on this photosensitive emulsion layer 2C. This light-sensitive emulsion layer 2c is covered with a protective layer 3, and this protection! It'! 3 is a ti shadow, which is formed in the process described below after the development process is completed.

Mechanism for transporting photographic light-sensitive material from coating section Photographic light-sensitive material 2 is supplied from a card slot 100 of the apparatus main body 1 to a reversing mechanism 301 via a guide 300, with the photosensitive surface of the photographic light-sensitive material 2 facing downward. This reversing mechanism 301 reverses the photosensitive material 2, transfers it to a guide 302 with the photosensitive surface facing upward, and supplies it to the coating mechanism.

Coating Mechanism The coating mechanism is disposed downstream of the card loading section A, as shown in FIG. 1, and a vat 400 stores UV curable resin liquid. This UV curable resin liquid is supplied to the transfer roll 402 by rotation of the pickup roll 401, and is applied to the gap between the transfer roll 402 and the back roll 403 when the photosensitive material 2 is passed through.

The transfer roll 402 is made of rubber, and the pickup roll 401 and back roll 403 are made of metal. This pickup roll 401 has a rough surface.
The pumping amount of the V-curing resin liquid can be dynamically controlled, and the surface of the back roll 403 is also roughened so that the photographic material 2 can be easily conveyed.

The pickup roll 401 can move eight times, and the contact pressure with the transfer roll 402 can be adjusted. Further, a predetermined gap is formed between the back roll 403 and the transfer roll 402, and this gap is also formed between the back roll 403 and the transfer roll 402.
It can be adjusted by moving the thickness of the photosensitive material 2, and is set to be smaller than the thickness of the photographic material 2.

The transfer roll 402 is driven by a motor 404, and its power is transmitted from a gear (not shown) of the transfer roll 402 to the gears of the pickup roll 401 and the back roll 403, which rotate in conjunction with each other.

A plate-shaped heater 405 is provided at the bottom of the bat 400, and a temperature detection sensor 406 is provided near the pickup roll 401. Temperature information obtained from the temperature detection sensor 406 is input to the control section H. This control unit H controls the heater 405 to control the UV curable resin liquid to a predetermined temperature, for example, 37°C.

Further, this vat 400 is provided with a replenishment tank 407 for replenishing the UV curable resin liquid.
The tip of the supply pipe 407a of No. 7 is opened by cutting diagonally, and when the liquid level of the UV curable resin liquid in the vat 400 decreases, the UV curable resin liquid is automatically supplied from the replenishment tank 407.

The coating on this coating area is carried out as follows. The UV curable resin liquid is drawn up by the rotation of the pickup roll 401 and supplied to the transfer roll 402. Transfer roll 402
With a predetermined rotation of , the UV curable resin liquid becomes a constant film thickness, for example, 10 to 15 μm. The film thickness formed on this transfer roll 402 depends on the viscosity of the UV curable resin liquid, the rigidity and rotational speed of the pickup roll 401, and this transfer roll 402 is UV cured by directly contacting the pickup roll 401. Since the UV curable resin liquid is supplied, the occurrence of liquid pooling between the two is reduced, and the film thickness of the UV curable resin liquid is always uniform, allowing continuous application.

A UV irradiation section is disposed downstream of the UV irradiation section type cloth section, and the UV curable resin liquid of the photographic light-sensitive material 2 conveyed via the conveyor belt 304 is irradiated with ultraviolet rays and cured. For example 3~
A protective layer 3 having a thickness of 7 μm is formed.

The photosensitive material 2 is cut in advance to the size of the ID card I, and a conveyor belt 30 conveys the photosensitive material 2.
4 is used from a position below the application section to the embossed section F, and the photosensitive material 2 is conveyed in the direction of the embossed section F by the drive of a drive motor 303. For example, a metal mesh belt is used as the conveyor belt 304 to reduce the heat effect of ultraviolet rays. For example, it is preferable to use a belt with a mesh size of 100 or less for better cooling efficiency.

A UV irradiation unit is disposed above the conveyor belt 304, and the UV curable resin liquid of the photographic light-sensitive material 2 is irradiated with ultraviolet light from a UV lamp 501 provided in a UV irradiation chamber 500 to cure it.

For example, a high-pressure mercury lamp is used as the UV lamp 501, and is provided in a lamp house 502. lamp house 502
The lamp house 5 is formed into a box shape with an opening at the bottom.
A vent (not shown) is formed in the lamp house 502 to easily take air into the lamp house 502.
This improves the cooling efficiency of 1.

The UV lamp 501 has a reflecting mirror 503, and the reflecting mirror 503 reflects ultraviolet light to irradiate the photosensitive material 2. The longitudinal direction of this UV lamp 501 is the photosensitive material 2.
When the photosensitive material 2 is conveyed by the conveyor belt 304, the time for the ultraviolet rays from the UV lamp 501 to pass through becomes longer, and the curing of the UV curing resin liquid can be accelerated.

The UV irradiation chamber 500 is partitioned with a heat insulating material and has an irradiation window 50.
4 is provided with a cold filter 505 to block the heat of the UV lamp 501 from being transmitted to the outside. U
An air inlet 507 is formed in the lower part of the V irradiation chamber 500 via a filter 506, and an air exhaust port 509 having a fan 508 is formed in the upper part, thereby forming an air passage for flowing air from below to upward. .

When the fan 508 is driven, air is introduced from the lower air inlet 507, enters the lamp house 502, directly cools the UV lamp 501, and is discharged to the outside of the apparatus main body 1 from the upper air exhaust port 509. . Note that the air passage may be formed so that air flows from above to below.

In this way, the air passage formed in the UV irradiation chamber 500 directly cools the UV clamp 01 itself, and the heat insulating material that partitions the UV irradiation chamber 500 blocks the heat of the U clamp ol from being transmitted to the outside. As a result, the heat effect on the UV curable resin liquid at the application section is reduced, and it is possible to arrange the device close to the application section, resulting in a smaller device.

Embossed part F U■ An embossed part F is arranged after the irradiation part E, and the photographic light-sensitive material 2 is formed with the application part and the UV irradiation part.
An emboss is formed on the protective layer 3 of the ID card I to prevent imitation and theft of the ID card I.

This embossing is formed when the photographic light-sensitive material 2 is passed between the embossing roll 600 and the back roll 601 arranged above and below, and is formed only on the protective layer 3 of the photographic light-sensitive material 2, and does not damage the image area. It is designed so that it never happens. This embossing includes, for example, one that stamps a predetermined shape or one that adds a striped pattern.

Air Conditioning Section G An air conditioning section G is arranged above the UV irradiation section E, and is used to cool and clean the air inside the apparatus main body 1 and to make it under a positive pressure. This air conditioning section G includes a fan 700 and this fan 70.
It cleans the air inside the device main body l, which is composed of filters 701 and 702 placed before and after 0, to prevent dust from adhering to the UV curable resin liquid, and also creates a positive pressure to remove the air inside the device main body i from the outside. This prevents dirty air from entering the interior. This positive pressure is set to, for example, a pressure at which the water column rises by 2 to 3 meters.

Furthermore, the capacity of the fan 700 is set to maintain the internal temperature of the apparatus main body 1 at 25 to 32 degrees Celsius or less, and the heater 405 is driven by temperature information from the temperature detection sensor 406 at the coating section, and UV curing is performed. Temperature resin liquid at 37℃, for example.
It is easy to hold and control.

Furthermore, the control section H controls each driving means of the card conveyance path C, the coating section, the UV irradiation section E1, the embossed section F, and the air conditioning section G.

[Effects of the Invention] As described above, the present invention forms a card conveyance path for conveying a card-shaped photosensitive material inside the main body of the apparatus, and along this card conveyance path, UV curing which is stored by a pickup roll is carried. an application section that supplies a UV curable resin liquid to a transfer roll and applies the UV curable resin liquid to the photosensitive material that is conveyed through the gap between the transfer roll and the back roll; and a U irradiation chamber that is partitioned by a heat insulating material. The apparatus is equipped with a UV irradiation section for irradiating ultraviolet rays to cure the UV curable resin liquid of the photosensitive material, and an air conditioning section for cooling, purifying, and positive pressure the air inside the main body of the apparatus. The air conditioner cleans the air inside the device body, creates positive pressure to prevent dirty air from entering from the outside, prevents dust from adhering to the UV curable resin, and Since the heat of the UV irradiation part is prevented from affecting the application part, the UV curable resin liquid can be applied under appropriate application conditions, and uniform application is possible.

In addition, the pickup roll in the application section removes the accumulated UV.
Since the curable resin liquid is directly supplied to the transfer roll, the film thickness of the UV curable resin liquid on the transfer roll becomes constant, allowing continuous and uniform application.

Furthermore, the UV irradiation section is housed in a U irradiation chamber separated by U clamp insulation material, which prevents the influence of heat on the application section, so the UV irradiation section and application section are placed close together. This makes it possible to downsize the device.
