By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventors TOBE, Kenji (Tsukuba-shi, JP); SHIMOKAWA, Hiromichi (Tsukuba-shi, JP); MIYOSHI, Tomoya (Tsukuba-shi, JP); TATENO, Masaya (Tsukuba-shi, JP); OHNAMI, Atsushi (Tsukuba-shi, JP), filed on December 21, 2017, was made available online on July 5, 2018, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to Komori Corporation.

The following quote was obtained by the news editors from the background information supplied by the inventors: "A liquid transfer apparatus which transfers liquid (for example, coating liquid such as varnish) to a print medium (sheet or web) includes an impression cylinder configured to convey the print medium, a coater cylinder (blanket cylinder) in contact with the impression cylinder, and an anilox roller (engraved roller) in contact with the coater cylinder. The liquid supplied to the anilox roller by a liquid supplying device (chamber device) is transferred to the print medium on the impression cylinder via the coater cylinder.

"Various types of anilox rollers are selectively used for the transfer of the liquid to the print medium by the liquid transfer apparatus, depending on the content of printing performed on the print medium. The various types of anilox rollers vary in a cell shape, a cell volume, and the like of engraving formed on a surface of the anilox roller. Accordingly, when the printing content is changed in a printing apparatus, the anilox roller sometimes has to be changed (switched) in the liquid transfer apparatus depending on the changed printing content. Examples of the technique for switching the anilox roller in the liquid transfer apparatus as described above include one described in Patent Literature 1."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "Technical Problem

"In the technique described in Patent Literature 1, a revolver magazine which can hold four screen rollers is provided above a cylinder (plate cylinder or blanket cylinder). The screen roller to be used is moved to a specified position by rotating the revolver magazine and the worker moves the screen roller disposed at the specified position to an active position (print position) in contact with the cylinder, by using a crane.

"However, in the technique described in Patent Literature 1, the worker has to perform work of switching the roller (work of moving the roller to the print position) by using the crane in a small space between units in the printing press. The work of switching the roller by using the crane in such a small space between units is poor in workability and takes time.

"Moreover, since the roller is moved (conveyed) by the crane in the small space between units, the roller may come into contact with peripheral members around the roller. Such contact between the roller and the peripheral members may damage the roller or the peripheral members.

"The present invention has been made in view of the aforementioned problems and an object is to facilitate switching of a roller in a liquid transfer apparatus.

"Solution to Problem

"A first aspect of the present invention for solving the aforementioned problems provides a liquid transfer apparatus characterized in that the liquid transfer apparatus includes: rollers configured to transfer supplied liquid to a blanket cylinder; a roller holding device configured to detachably hold the rollers and perform a rotating operation to move any one of the rollers to a predetermined position facing the blanket cylinder; and a contact-separation unit configured to bring the roller held by the roller holding device and disposed at the predetermined position into and out of contact with the blanket cylinder.

"A second aspect of the present invention for solving the aforementioned problem provides the liquid transfer apparatus according to the first aspect, characterized in that the liquid transfer apparatus includes an alignment unit configured to determine positions of the rollers relative to the roller holding device.

"A third aspect of the present invention for solving the aforementioned problem provides the liquid transfer apparatus according to the first or second aspect, characterized in that the liquid transfer apparatus includes a position fixation unit configured to fix a position of the roller held by the roller holding device and disposed at the predetermined position.

"A fourth aspect of the present invention for solving the aforementioned problem provides the liquid transfer apparatus according to any one of the first to third aspects, characterized in that the liquid transfer apparatus includes a printing pressure adjustment unit configured to adjust printing pressure between the blanket cylinder and each of the rollers being at the predetermined position.

"Advantageous Effects of Invention

"In the liquid transfer apparatus according to the first aspect, a worker does not have to perform work of switching the roller (work of moving the roller to a print position) by using a crane in a small space between units in a printing press and can easily perform the switching of the roller in the liquid transfer apparatus. Accordingly, there is no risk of bringing the roller into contact with peripheral members around the roller and damaging the roller or the peripheral members.

"In the liquid transfer apparatus according to the second aspect, each of the rollers held by the roller holding device can be moved to any position (phase) by the rotating operation of the roller holding device.

"In the liquid transfer apparatus according to the third aspect, the roller can be brought into and out of contact with the blanket cylinder at the same position every time.

"In the liquid transfer apparatus according to the fourth aspect, a state of the liquid to be transferred can be adjusted."
