[0071] figure 1 It is a perspective view showing the overall structure of an embodiment of the liquid application device 100 of the present invention. The liquid application device 100 shown here generally includes: a liquid application unit for applying a predetermined application liquid to a medium (hereinafter also referred to as application medium) as an object to apply the liquid; and A liquid supply unit for supplying a coating liquid to the liquid coating unit.

[0072] The liquid application unit includes a cylindrical application roller 1001 , a cylindrical counter roller (medium support member) 1002 arranged to face the application roller 1001 , and a roller drive mechanism 1003 for driving the application roller 1001 . The roller driving mechanism 1003 includes a roller driving motor 1004 and a power transmission mechanism 1005 having a gear train for transmitting the driving force of the roller driving motor 1004 to the application roller 1001 .

[0160] Figure 20 It is a lookup table for determining the number of preliminary spins (preparatory spin time) in this embodiment. The pretreatment operation in this embodiment is to discharge the thickened and adhering material of the coating liquid remaining on the coating roller and in the liquid holding member when the device is not used for a long time, for example, ΔT is greater than or equal to 24 hours. dust on. That is, this is a control method for recovering the coating liquid at least once after performing a certain number of preliminary rotations.

Abstract

The present invention provides a liquid application device, an inkjet recording device, and a recording device capable of performing an appropriate application initial operation according to the length of standby time and power-off time, and a control method of the liquid application device. In the present invention, the information related to the end time of the previous process for recovering liquid is read from the nonvolatile memory, and the current time information indicating the current time is obtained, and the information from the end time of the previous recovery to the present time is obtained. Information about the elapsed time from the start time of the second application. Thereafter, the preliminary rotation number R of the application roller is determined based on the information on the elapsed time and by referring to the lookup table. Therefore, the pretreatment operation is performed by rotating the coating roller at the determined number of preliminary rotations R.

Description

technical field [0001] The present invention relates to a liquid application device and an inkjet recording device. In particular, the present invention relates to a liquid application device and an inkjet recording device for applying a liquid to a medium for a specific purpose such as promoting the separation of a pigment when recording with an ink containing a pigment as a coloring material. condensation. Furthermore, the invention also relates to a method of controlling the liquid application device. Background technique [0002] It is well known that for an inkjet recording device such as a printer, a treatment liquid that insolubilizes or coagulates the coloring material of the ink is used to improve recording quality such as bleeding, density, tone, and offset, and to improve such properties as water resistance and weather resistance. Image firmness. [0003] One of the methods of applying the treatment liquid to the recording medium is to spray the treatment liqui...
