Problems solved by technology

[0009] However, in the inkjet printer of Patent Document 1, there is no problem when printing on one side, but in the case of paper on which images are printed on both sides, there is insufficient drying of the ink on the side that does not face the drying device. , does not adequately suppress curl concerns
[0010] Therefore, there is a problem that stack failure due to curling occurs when paper sheets on which images are printed by an inkjet printer are sequentially placed on the processing tray.

[0084] First, the configuration of the printing device will be described. figure 1 is a schematic diagram showing the configuration of a printing device, figure 2 is a configuration diagram showing the configuration of the printing unit, image 3 It is a configuration diagram showing the configuration of the intermediate unit. Such as figure 1 As shown, the printing device 1 according to the present embodiment includes a printing unit 100 as a printing unit and a post-processing device 2 disposed on the side of the printing unit 100 .

[0085] Furthermore, the post-processing device 2 includes an intermediate unit 200 and a post-processing unit 300 as a post-processing unit. The printing unit 100 is, for example, a device that prints an image on paper M as a medium. In addition, the printing unit 100 includes a control unit 10 for overall controlling the driving of each mechanism in the printing device 1 . The post-processing unit 300 is, for example, a device...

[0210] Next, the tension applying mechanism of the intermediate unit 200a according to the second embodiment of the present invention will be described. Figure 15 It is a schematic diagram for explaining the operation of the tension applying mechanism of the intermediate unit according to the second embodiment. It should be noted that the same reference numerals are assigned to the same components as those in the first embodiment, and overlapping descriptions will be omitted.

[0211] The intermediate unit 200a according to the second embodiment is different from the intermediate unit 200 of the first embodiment in that it does not include the guide plate 271 for guiding the paper M during drying, but includes a tension applying mechanism.

[0212]

[0213] The intermediate unit 200a is provided with a tension applying mechanism for applying tension to the paper M in order to suppress deformation such as curling of the paper M. Such as Figure 15 As shown, the tension imp...

[0243] Next, the tension applying mechanism of the intermediate unit 200b according to Modification 1 of the second embodiment of the present invention will be described. Figure 17 It is a schematic diagram for explaining the operation of the tension applying mechanism of the intermediate unit 200b according to Modification 1 of the second embodiment. It should be noted that the same reference numerals are assigned to the same components as those in the first embodiment, and overlapping descriptions will be omitted.

[0244] The intermediate unit 200b according to Modification 1 is different from the intermediate unit 200a of the second embodiment in that the pressure roller 280 is provided in the tension imparting mechanism.

[0245] In the intermediate unit 200b, a pressure roller 280 is provided in the tension applying mechanism. The pressure roller 280 is arranged at a position facing the paper M on the downstream side of the second roller pair 268 b in the direction in ...

Abstract

The present invention provides an intermediate unit, a post-processing device, and a printing device that suppress curling of paper on which images are printed. The intermediate unit of the present invention has a conveying path capable of conveying the paper printed by the printing unit to a post-processing unit for post-processing the paper, wherein the printing unit uses ink to print the paper as a medium, and is set on the conveying path There is a drying unit to facilitate paper drying.

Description

[0001] Japanese Patent Application No.2017-089382 filed on April 28, 2017, Japanese Patent Application No.2016-138251 filed on July 13, 2016, Japanese Patent Application No. 2016-138252 and Japanese Patent Application No. 2016-138253 filed on July 13, 2016 are hereby incorporated by reference in their entirety. technical field [0002] The invention relates to an intermediate unit, a post-processing device and a printing device. Background technique [0003] Conventionally, as an apparatus for printing an image on paper, for example, an inkjet printer equipped with a recording head that discharges liquid ink as droplets is known. [0004] However, when an image is printed using an inkjet printer, the paper on which the image is printed may curl (a state such as a part of the paper being bent and deformed) due to absorption of ink (moisture) or drying of the ink. [0005] Therefore, Patent Document 1 discloses an inkjet printer capable of preventing curling by including a dr...
