The flow of drying in the drying device 104 configured as described above is as follows. Dry the liquid application surface by spraying the surface.

Next, the surface of the continuous paper 110 opposite to the surface to which the liquid is applied is heated while being passed over the heating drum 12 arranged inside the plurality of heating rollers 11 , and the second air supply unit 21 supplies an air flow (air) to the liquid. The application surface is sprayed to dry the liquid application surface.

After that, while the guide roller 13 is brought into contact with the liquid-applied surface of the continuous paper 110 , the surface of the continuous paper 110 opposite to the liquid-applied surface is brought into contact with the heating roller 11 again to heat the continuous paper 110 . (Air) is blown onto the liquid application surface to dry the liquid applied to the continuous paper 110 . That is, in the present embodiment, the continuous paper 110 to be dried is brought into contact with the same plurality of heating rollers 11 from different directions to heat the object to be dried.

FIG. 4 is an explanatory diagram of an air supply device in the drying apparatus shown in FIGS. 2 and 3. FIG.

The drying device 104 has a front side plate 81 , a rear side plate 83 and a housing 85 . Between the front side plate 81 and the rear side plate 83, the heating drum 12, the heating roller 11, the air supply section 31, and the second air supply section 21 are arranged. A drum flange 12f and a roller flange 11f that rotatably support the heating drum 12 and the heating roller 11 are provided outside the front side plate 81 and the rear side plate 83, respectively.

Between the rear side plate 83 and the housing 85, there are provided a fan 20, which is an example of a blowing section that blows air toward the drum flange 12f of the heating drum 12, and a duct 71 that feeds the air around the drum flange 12f to the air supply section 31. are placed.

At a position outside the fan 20 in the housing 85, a vent 20A is formed through which the fan 20 takes in the air outside the housing 85. As shown in FIG. The fan 20 sends out the normal temperature air outside the housing 85 taken in from the vent 20A toward the drum flange 12f. As a result, the drum flange 12f heated to a high temperature by the heat source of the heating drum 12 is cooled, and overheating of the drum flange 12f is suppressed.

The duct 71 has an intake port 711 for taking in air around the drum flange 12f, an air supply port 713 connected to the air supply portion 31, and a second air supply port 712 connected to the second air supply portion 21. , distributes the air taken in from the suction port 711 and sends it to the air supply unit 31 and the second air supply unit 21 . The suction side (upstream side) of the fan 20 has a negative pressure, and the delivery side (downstream side) of the fan 20 has a positive pressure. The air that is sent out toward the drum flange 12f and hits against the drum flange 12f and heated is taken in from the suction port 711. As shown in FIG. As a result, the room-temperature air taken in through the air vent 20</b>A is prevented from being taken in directly through the suction port 711 .

The air supply portion 31 is arranged downstream of the second air supply portion 21 in the air flow direction, and the duct 71 has a second air supply port 712 connected to the second air supply portion 21 . and the air supply port 713 connected to the air supply portion 31 is arranged so as to be close to the roller flange 11 f of the heating roller 11 . Since the roller flange 11f is heated to a high temperature by the heat source of the heating roller 11, the air between the rear side plate 83 and the housing 85 is also heated by heat transfer from the roller flange 11f. As a result, the portion of the duct 71 adjacent to the roller flange 11f is also heated, so that the air passing through the duct 71 is heated or kept warm.

In this embodiment, the fan 20, the air vent 20A, the duct 71, the air supply section 21, and the second air supply section 31 constitute an air supply device.

The drying device 104 includes an air supply unit 31 that feeds air toward the continuous paper 110 positioned upstream or downstream of the heating drum 12 in the conveying direction, and air around the heating drum 12 (drum flange 12f). The heating drum 12 (drum flange 12f) is provided with the liquid application surface of the continuous paper 110 located upstream or downstream of the heating drum 12 in the conveying direction. You can apply the warm air around you. As a result, drying of the continuous form paper 110 located upstream or downstream in the transport direction of the heating drum 12 can be accelerated, and the drying efficiency is improved.

That is, since the continuous paper 110 directly facing the heating drum 12 is sufficiently heated by the heating drum 12, the continuous paper 110 heated by the heating drum 12 is heated by the heating drum 12. Also, the heating drum 12 blows warm air toward the unheated continuous paper 110 to improve the drying efficiency.

The drying device 104 also includes a fan 20 for sending air to the heating drum 12 (drum flange 12f), and a duct 71 supplies the air sent from the fan 20 toward the heating drum 12 (drum flange 12f). By sending it to the air section 31, the heating drum 12 (drum flange 12f) can be cooled, and the warm air around the heating drum 12 (drum flange 12f) can be effectively utilized, thereby improving the drying efficiency.

Furthermore, the duct 71 distributes the air around the heating portion of the heating drum 12 (drum flange 12 f ) to the air supply portion 31 and the second air supply portion 21 , so that the continuous line facing the heating drum 12 is Warm air around the heating drum 12 (drum flange 12f) can also be applied to the paper 110 to promote drying. That is, compared to a configuration in which warm air is applied to only the continuous paper 110 located upstream or downstream in the transport direction of the heating drum 12 or only the continuous paper 110 at a position facing the heating drum 12. , the area where the continuous paper 110 receives warm air is expanded, so that the drying efficiency is increased.

Also, the air supply unit 31 sends air toward the continuous paper 110 heated by the heating roller 11 . As a result, drying of the continuous paper 110 located upstream or downstream in the transport direction of the heating drum 12 can be further accelerated.

Since the duct 71 is arranged so that the portion between the second air supply portion 21 and the air supply portion 31 is close to the roller flange 11f of the heating roller 11, the air sent to the air supply portion 31 is , is reheated or kept warm by the heat of the heating roller 11 . As a result, the temperature of the air sent from the air supply unit 31 can be prevented from lowering, and drying of the continuous paper 110 located upstream or downstream of the heating drum 12 in the transport direction can be promoted.

FIG. 5 is a perspective explanatory view of an air supply unit in the drying apparatus shown in FIGS. 2 and 3. FIG.

The air supply unit 31 includes an air supply chamber 51 that is connected to the air supply port 713 of the duct 71 and serves as a flow path, a nozzle 52 that is an outlet for blowing out the air that communicates with the air supply chamber 51, and the air supply chamber 51. and exhaust chambers 53, 53 arranged on both sides in the short direction of.

An exhaust hole 61 is provided in the exhaust chamber 53, and the exhaust chamber 53 is connected to a suction fan through a duct. The air supply unit 31 is arranged so that the nozzle 52 and the exhaust hole 61 face the liquid applying surface of the continuous paper 110 .

The air supply unit 31 guides the warm air around the heating drum 12 to the nozzle 34 through the duct 71 and blows out the air from the nozzle 34 .

The exhaust chamber 53 collects warm air containing moisture and solvent generated when the continuous paper 110 is heated by the heating roller 11, and the exhaust chamber 53 is not cooled by the collected air. In addition, since the air supply chamber 52 also flows the warm air around the heating drum 12 (drum flange 12f), it is difficult to cool. As a result, when the continuous paper 110 is heated by the heating roller 11 or the like, vapor of the solvent contained in the liquid is generated. It is possible to suppress the occurrence of dew condensation.

Further, the air supply portion 31 is made of a material having a thermal conductivity of 1 W/(m·K) or less. As a material having a thermal conductivity of 1 W/(m·K) or less, for example, resin materials such as engineering plastics such as polyacetal and polyamide can be used. As a result, even if warm air containing moisture or a solvent generated by being heated by the heating roller 11 comes into contact with the inner peripheral surface or the outer peripheral surface of the air supply chamber 51, dew condensation is unlikely to occur.

Therefore, it is possible to prevent deterioration of image quality such as dew condensation falling on the printing surface of the continuous paper 110 and staining the printed image.

Instead of forming the entire air supply unit 31 with a material having a thermal conductivity of 1 W/(m·K) or less, the wall separating the air supply chamber 51 and the exhaust chamber 53 and the air supply chamber 52 Only the wall in contact with the outside air may be made of a material with a thermal conductivity of 1 W/(m·K) or less. Alternatively, a sheet made of a material having low thermal conductivity such as foam or rubber may be attached to the wall surface of the air supply portion 31 made of metal.

The intake ports 711A-711J are arranged closer to the heating drum 112 than the air supply units 31A-31J. Although illustration of the air supply units 31L to 31Q shown in FIG. 3 is omitted, they are configured in the same manner as the air supply units 31A to 31J.

That is, a plurality of pairs of ducts 71A-71J, air supply portions 31A-31J and second air supply ports 712A-71J are provided.

As a result, the warm air around the heating drum 12 (drum flange 12f) can be applied to a plurality of locations of the continuous paper 110 located upstream or downstream in the transport direction of the heating drum 12. Improves drying efficiency.

In addition, since the warm air around the heating drum 12 (drum flange 12f) can be applied to a plurality of locations of the continuous paper 110 facing the heating drum 12, the drying efficiency is improved.

A plurality of ducts 71A to 71J are radially arranged corresponding to the plurality of air supply sections 31A to 31K being arranged to surround the heating drum 12 .

As a result, the distances from the suction ports 711A to 71J to the air supply ports 713A to 713J in the plurality of ducts 71A to 71J are substantially the same, and the temperature of the air sent out from the plurality of air supply portions 31A to 31K is substantially the same. Therefore, it is possible to reduce drying unevenness at a plurality of locations on the continuous paper 110 located upstream or downstream of the heating drum 12 in the transportation direction.

In addition, the air supply units 31A to 31J are arranged downstream of the second air supply units 21A to 21J in the air flow direction, respectively, and the duct 71 is connected to the second air supply units 21A to 21J. The portions between the air portions 31A to 31J are arranged so as to be close to the heating rollers 11A to 11J, respectively.

As a result, the temperature of the air sent from the air supply units 31A to 31J can be prevented from dropping, and drying of the continuous paper 110 located upstream or downstream of the heating drum 12 in the transport direction can be promoted.

In the above embodiment, an example in which continuous paper is used as the object to be dried and printed is described, but the present invention is not limited to this.
