DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overcoat apparatus for applying an overcoat to a card.

[0002]

2. Description of the Related Art Heretofore, for example, there has been known a card which is overcoated to protect a printing surface. In this apparatus for applying an overcoat to a card, a platen roller and a heat roller are disposed to face each other, and a card and an overcoat ribbon pass between the platen roller and the heat roller from one side to the other. It has become. The platen roller and the heat roller have smooth and cylindrical pressing surfaces so as to cover the entire surface of the card.

An overcoat ribbon is formed by laminating an overcoat film on a base film so that the overcoat film can be peeled off. When the overcoat ribbon and the card are laminated and heated and pressed by a heat roller, the overcoat film adheres to the surface of the card. Then, the surface of the card is overcoated. The overcoated card is stored in a stacker or the like through a guide roller for conveyance.

[0004]

However, in the conventional overcoating apparatus, if the overcoating operation for covering the entire surface of the card with the overcoat film by heating and pressing the heat roller is continued, the heat of the heat roller is reduced by the heat roller and the heat roller. The temperature may accumulate on the platen roller and become high. If this high temperature condition continues, the softening state of the adhesive of the overcoat film becomes remarkable, and when the overcoat film separates from the base film after passing between the heat roller and the platen roller, the adhesive of the overcoat film is removed. The card is cooled while the thread is pulled, and burrs may be generated at the rear end of the card in the transport direction.

The overcoat apparatus of the present invention has been made in view of such a problem. When overcoating a card with an overcoat film, heat is accumulated on a heat roller or a platen roller and the rear end of the card is overheated. It is an object of the present invention to disclose an overcoat apparatus that removes burrs during transportation of a card even if burrs are generated in the section.

[0006]

In order to solve the above-mentioned problems, an overcoating apparatus according to the present invention comprises a platen roller and a heat roller, which heat and press the overcoat ribbon and the card, and then pressurize the overcoat. In an overcoating device that separates the overcoated ribbon and the card by a peeling roller that guides the coated ribbon, and removes the peeled card by a pair of transporting rollers, the overcoating device is disposed between the peeling roller and the pair of transporting rollers. And a cutter for cutting off burrs protruding from an end of the card.

[0007]

According to the overcoat apparatus of the present invention,
With a cutter disposed between the transport roller and the peeling roller, the rear end of the card sandwiched between the transport rollers can be cut to remove burrs.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an overcoat apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a main configuration of an overcoat apparatus according to an embodiment of the present invention. The overcoat device 1 is provided in a card maker that records characters or images on the plastic card 2 by recording magnetic data or the like on the plastic card 2 and then using a thermal head, an indirect transfer device, a laser device, or the like. In addition, the image rendering method of the card making machine is inkjet type,
There are also types such as electrostatic copying, but plastic card 2
After the magnetic data is recorded, an image is drawn and is carried into the overcoat apparatus 1 for overcoating the image. However, the overcoat apparatus 1 does not have to be a part of the above-described card making machine, and the present invention can be applied to the overcoat apparatus 1 alone.

The overcoat apparatus 1 includes a housing and a chassis (not shown), and a platen roller 4 and a heat roller 5 for guiding the plastic card 2 and the overcoat ribbon 3 are rotatably supported by the chassis. I have. The heat roller 5 can adjust the pressure by coming into contact with and separating from the platen roller 4, and the platen roller 4 transmits the rotational driving force. The overcoat ribbon 3 is guided by a guide roller 6 and a peeling roller 7 from an unwinding reel to a take-up reel driven by a motor, and includes a base and an overcoat layer. Heat roller 5 for overcoat layer
Is applied to the surface of the plastic card 2 to cover the printing surface of the plastic card 2. The base and the plastic card 2 are separated by the peeling roller 7, and the overcoat layer adhered to the plastic card 2 and the base are peeled. A heater 8 and a reflection plate 9 are provided on the heat roller 5 to heat the surface of the heat roller 5. The heat roller 5 is formed of a heat-resistant silicone rubber cylindrical cylinder, and can accumulate radiant heat from the heater 8 and the reflection plate 9. The platen roller 4 is coated with a heat-resistant resin so that the plastic card 2 can be moved.
Can be conveyed from the guide roller 6 toward the peeling roller 7. Behind the nip position N between the heat roller 5 and the platen roller 4, a pair of transport rollers 1
The plastic cards 2 are fed from the nip position N in the direction of arrow A in FIG.

A cutter 11 protruding from the rear end of the plastic card 2 by its own weight is provided between the transport rollers 10, 10 and the peeling roller 7. Cutter 11
Is axially supported by a pin 12 so as to be a fulcrum. The other end of the cutter 11 is a stopper 1
3 to be supported. Cutter 11
Is a slope 11a for lifting the cutter 11 by the force of the plastic card 2 moving from the peeling roller 7 to the transport rollers 10, 10, and a vertical plate 11b for lowering the cutter 11 along the rear end of the plastic card 2. have.

The stopper 13 is provided for the plastic card 2
Supports the cutter 11 so that the inclined surface 11a is positioned in the moving area of the plastic card 2 so that the plastic card 2 can push up the cutter 11, and the plastic card 2 advances from the nip position N toward the cutter 11 so as to move. When the plastic card 2 comes, the cutter 11 is raised upward by the inclined surface 11a and passes under the cutter 11, and when the plastic card 2 passes below the cutter 11, the vertical plate portion 11b of the cutter 11 is It descends along the rear end. Plastic card 2
Since the vicinity of the rear end portion is held by the pair of transport rollers 10, 10, the cutting edge of the cutter 11 does not shift, and the burr of the plastic card 2 is cut cleanly.

In the above embodiment, the burrs at the rear end of the plastic card 2 are cut by the weight of the cutter 11, but the burrs may be cut automatically, or the rear end of the plastic card 2 may be , The rotation of the transport rollers 10, 10 may be temporarily stopped. Further, the heat roller may have a heat source therein. The heater may be provided inside or outside the platen roller.

[0014]

According to the overcoating device of the present invention, the rear end of the plastic card sandwiched between the transport rollers is removed by a cutter disposed between the transport roller and the peeling roller to remove burrs. it can.
