The second drying means is not limited to the hot air blowing means 302, and radiation heating means such as an IR heater can also be used.

Here, for example, a glass fiber mesh belt can be used as the suction conveying belt 301 . By using the mesh belt, it is possible to reduce fluttering of the sheet material P due to rebounding of the hot air blown from the hot air blowing means 302 .

The amount of heat given to the sheet material P by the hot air blowing means 302 as the second drying means is made larger than the amount of heat given to the sheet material P by the IR heater 60A as the first drying means.

In this manner, the sheet material is dried by the IR heater 60A as the first drying means 60 on the transfer path of the transfer drum 25 for transferring the sheet material P from the drum 51 to the suction transfer belt 301 of the suction transfer mechanism 31, which is the transfer means.

Then, by performing drying by the second drying means (drying mechanism section 32) in this state, it is possible to reliably fix and prevent peeling of the printed surface.

Further, as described above, when a mesh belt is used as the suction conveying belt 301, if the sheet material P is placed on the mesh belt having a net shape on the surface in a state where the water-based liquid (ink) is not very dry, the belt 301 It has been confirmed that a pattern corresponding to the shape of the net of the mesh belt appears in the image due to non-uniform contact between the belt and the sheet material P or the like.

Therefore, as in the present embodiment, by performing drying (pre-drying) by the first heating means before drying (main drying) by the second heating means on the suction conveying belt 301, the traces of the mesh belt are removed. Abnormal images that appear in images can be prevented. In other words, when a water-based liquid (ink) is applied to the sheet material and drying is performed while the sheet material is conveyed by a mesh belt, pre-drying before placing the sheet material on the mesh belt will cause abnormalities. Image generation can be prevented.

Further, by using the ink containing at least water as the liquid as in the present embodiment, it is possible to perform heat drying by the first drying means 60 and heat drying by the second drying means (drying mechanism section 32). .

On the other hand, for example, in the case of using an ultraviolet curable ink, when the ink is cured by UV irradiation at a position corresponding to the first drying means 60 (transfer path by the transfer cylinder 25), the second The need for drying at the drying means is eliminated.

Next, the first drying means in the second embodiment of the invention will be explained with reference to FIG. FIG. 5 is an explanatory diagram of a main part for explaining the first drying means.

In this embodiment, as the first drying means 60, warm air is blown from the back side of the transfer drum 25 to the liquid-applied surface of the sheet material P along the transfer path of the transfer drum 25. A means 60B is arranged.

Even with this configuration, it is possible to obtain the same effects as those of the first embodiment.

Next, the first drying means in the third embodiment of the invention will be described with reference to FIG. FIG. 6 is an explanatory diagram of a main part for explaining the first drying means.

In this embodiment, the first drying means 60 includes an IR heater 60A that heats the liquid-applied surface of the sheet material P from the opposite side of the transfer path of the transfer cylinder 25, and a hot air blower that blows hot air. Attachment means 60B are arranged.

By configuring in this way, the amount of heat given to the sheet material P can be made larger than in the first embodiment and the second embodiment.

A hot air blowing means 60B for blowing hot air is arranged.

As the first drying means 60, an IR heater 60A is arranged to heat the surface (rear surface) of the sheet material P opposite to the surface to which the liquid is applied with respect to the transfer path of the transfer drum 25. FIG.

By heating both the front surface and the rear surface of the sheet material P in this way, the sheet material P can be dried efficiently.

Further, preheating is performed in the delivery path by the delivery cylinder 25 having a diameter smaller than that of the drum 51, so that the sheet material P can be efficiently heated from the front surface and the back surface.

As described above, the transfer cylinder 25 is substantially hollow in the widthwise region where the sheet material P is held, except for the gripper 82, the holding member 84, and the rotating shaft 25a. Therefore, the hot air blown out from the hot air blowing means 60 can pass through the inside of the transfer cylinder 25 and blow onto the surface of the sheet material P gripped by the gripper 82 .

By using the transfer drum 25 having a diameter smaller than that of the drum 51, the position of blowing hot air across the transfer drum 25 and the conveying position of the sheet material P can be brought close to efficiently apply heat.
