[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gloss processing device that imparts gloss to an image surface of a recording sheet on which an image is formed.

[0002]

[Prior Art]

 Conventionally, as this type of gloss processing apparatus, an apparatus as shown in FIG. 2 has been used.

A roll-shaped laminating material 1 in which a heat-meltable layer 1 b is laminated on one surface of a plastic film 1 a is wound through a guide roller pair 2, a conveyance guide 3, a heating roller pair 4, and a conveyance roller pair 6. It is wound around the take-up roller 7. As the plastic film 1a, a polyester film, a polyimide film, a polycarbonate film or the like can be used, and the thickness thereof is suitably in the range of 5 μm to 50 μm. As the heat-fusible layer 1b, a substance that exhibits fluidity at 60 ° C. to 200 ° C. is used, and for example, polystyrene, styrene-butadiene copolymer, styrene-acrylic copolymer, etc. can be used, The thickness is suitably in the range of 1 μm to 20 μm.

The heating roller pair 4 is provided with a heater 5 therein, and is maintained at a temperature at which the heat-meltable layer 1 b of the laminate material 1 is melted, and is positioned so that a predetermined pressure is applied between the heating roller pair 4. Has been done.

The recording sheet 9 is conveyed toward the heating roller pair 4 by being sandwiched by the guide roller pair 2 in a state where the image portion 9 a formed on the surface and the heat-melting layer 1 b of the laminating material 1 are superposed on each other. To be done. When the recording sheet 9 and the laminating material 1 are pressed against each other between the heating roller pair 4, the heat-melting layer 1b of the laminating material 1 is melted by the heating from the heating roller pair 4, and the surface of the image portion 9a of the recording sheet 9 is melted. Transfer to.

In the laminate material 1 integrated with the recording sheet 9, only the plastic film 1a is taken up by the take-up roller 7 when it is carried out from the pair of carrying rollers 6, and the recording sheet 9 is placed on the surface of the image portion 9a. The heat-fusible layer 1b is laminated to give gloss to the image surface.

The degree of gloss of the image surface changes depending on the smoothness of the surface of the heat-fusible layer 1b laminated on the surface of the image portion 9a of the recording sheet 9. For example, if the surface of the heat-fusible layer 1b is a smooth surface such as a mirror surface, diffuse reflection of light is reduced and the degree of gloss is increased. On the contrary, if the surface of the heat-fusible layer 1b is a rough surface having irregularities, diffuse reflection of light increases and the degree of gloss decreases. Therefore, in the above gloss treatment equipment, in order to change the degree of gloss, prepare a laminate material in which a heat-meltable layer is formed on a plastic film with different surface roughness, and select from it. Was.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

First, the configuration of the present embodiment will be described with reference to FIG. The same members as those of the conventional technique are designated by the same reference numerals, and the description thereof will be omitted.

The two pairs of heating rollers 4a and 4b having different surface roughnesses are connected by a connecting member 10 and are held so as to be pressed against each other and separated from each other about the rotating shaft 11. The heating roller pair 4a is processed as a gloss roller pair with a surface roughness of 2 μm, and the heating roller pair 4b is processed as a semi-gloss roller pair with a surface roughness of 10 μm. The surface roughness of the plastic film 1a of the laminate material 1 is the same as or smaller than the surface roughness of the heating roller pair 4a. A gear 12 is fixed to one end of the rotating shaft 11 and meshes with a drive gear 14 fixed to the shaft of a motor 13.

Next, the operation of the gloss processing device of the present invention will be described. The recording sheet 9 on which the image is formed is sandwiched between the guide roller pair 2 and directed toward the heating roller pairs 4a and 4b in a state where the image portion 9a surface and the heat-melting layer 1b of the laminating material 1 are superposed. Be transported. When it is desired to make the image surface glossy, the drive gear 14 of the motor 13 rotates counterclockwise to rotate the gear 12 clockwise, and the connecting member 10 also rotates about the rotating shaft 11 to rotate the heating roller pair. 4a is held in a pressure contact state. When the recording sheet 9 and the laminating material 1 are pressed against each other between the heating roller pair 4a, the heat-melting layer 1b of the laminating material 1 is melted by the heating from the heating roller pair 4a, and the surface of the image portion 9a of the recording sheet 9 is melted. Transfer to. At this time, the surface state of the surface of the heat-fusible layer 1b is transferred by the pressure of the heating roller pair 4a. In the laminate material 1 integrated with the recording sheet 9, only the plastic film 1a is taken up by the take-up roller 7 at the time of being carried out from the carrying roller pair 6, and the recording sheet 9 is heat-melted on the surface of the image portion 9a. The functional layer 1b is laminated to give gloss to the image surface.

Next, when it is desired to make the image surface semi-glossy, the drive gear 14 of the motor 13 rotates in the clockwise direction to rotate the gear 12 in the counterclockwise direction, and the connecting member 10 with the rotating shaft 11 as the center. Also rotates, the heating roller pair 4a is separated, and the heating roller pair 4b is held in a pressure contact state. Similarly, by passing the recording sheet 9 and the laminating material 1 between the heating roller pair 4b, the surface state of the heating roller pair 4b is transferred to the surface of the heat-fusible layer 1b, and the image surface of the recording sheet 9 is half-printed. Gloss is imparted. In this way, by driving the motor 13, either the heating roller pair 4a or 4b can be selected, and the degree of light can be easily changed.

In the present embodiment, as the operation selecting means, the two heating roller pairs are pressed and separated by the motor to change the degree of gloss, but two heating rollers are used. It is also possible to select the heating roller pair by selecting and operating the heater of the heating roller pair while keeping the pair pressed.

Although only one of the two heating roller pairs is selected and operated by the operation selecting means, the heating roller pair for gloss is always operated and the image surface is semi-glossy. The pair of heating rollers for semi-gloss may be operated only when the state is desired.

Further, although the heating roller pair is used to heat and pressure bond the recording sheet and the laminate material, only the roller on the laminate material side may be the heating roller and the recording sheet side may be the pressure roller.

Furthermore, the surface roughness of the heating roller pair is not limited to that of the embodiment, and a suitable value can be used depending on the desired degree of gloss. Also, the surface roughness of the rollers on both the laminating material side and the recording sheet side need not be the same, and similar results can be obtained by changing only the surface roughness of the laminating material side rollers. You can
