Inkjet recording apparatus

Abstract

The invention provides an inkjet recording apparatus, including an image recording section which records an image on a front surface of a cut sheet recording medium by an inkjet method by using an aqueous ink; a chain gripper which receives the recording medium, on the front surface of which an image has been recorded, from the image recording section, and conveys the recording medium by gripping a leading end of the received recording medium; and a drying processing section which carries out a drying process on the recording medium conveyed by the chain gripper.

Description

technical field [0001] The present invention relates to inkjet recording devices, and more particularly, to inkjet recording devices that record images using aqueous UV inks. Background technique [0002] There is known an aqueous UV inkjet recording apparatus that records an image by an inkjet method using an aqueous medium-based UV (ultraviolet) curable ink (for example, see Japanese Patent Application Laid-Open No. 2011-46872). [0003] In an aqueous UV inkjet recording device, in order to fix a formed image, it is necessary to irradiate the image with UV (ultraviolet rays) after image formation. In addition, if ordinary printing paper (ie, not special inkjet paper but paper mainly composed of cellulose such as coated paper used in ordinary offset printing) is used, drying treatment is also required after image formation. [0004] In order to perform this UV irradiation process and drying process, in Japanese Patent Application Laid-Open No. 2011-37195, in an inkjet reco...

Problems solved by technology

[0007] However, as described in Japanese Patent Application Laid-Open No. 2011-37195, when paper is subjected to a drying process, in a configuration in which the paper is conveyed using drums and the drying devices are provided on the conveying path, the number of drying devices that can be installed is limited , and it is difficult to dry the paper quickly and efficiently

In other words, in order to quickly and efficiently dry the paper after image formation, it is necessary to arrange a plurality of drying devices at a high density, however, in order to arrange a plurality of drying devices at a high density, it is necessary to make the diameter of the conveying drum large so that the device's size increased

[0008] In addition, it is desirable to perform drying processing on the sheet immediately after image formation, however, as described in Japanese Patent Application Laid-Open No. nearby, the heat generated during the drying process heats the transfer drum, and the heat of the transfer drum dries the inkjet head, and there is a risk that droplet ejection accuracy will decrease

[0009] Similarly, in Japanese Patent Application Laid-Open No. 2006-305773, the conveyor belt is heated by drying heat, and the heat of the conveyor belt dries the inkjet head, and there is a risk that droplet ejection accuracy will be reduced
