Abstract
A printing press cleaning device includes a solvent supply nozzle (34) configured to supply a solvent containing a surfactant to an ink roller group (21) that includes a plurality of ink rollers configured to receive ink from an ink fountain (18a) and send the ink to a plate cylinder (17). The cleaning device includes a first or second cleaning solution supply nozzle (35, 36) configured to supply a first or second cleaning solution containing a volatile organic solvent to the ink roller group (21). The cleaning device includes a doctor blade (33) configured such that a distal end thereof can come into contact with and be moved away from an ink roller of the plurality of ink rollers, and scrape and collect the ink, the solvent, and the first or second cleaning solution of the ink roller group (21) at a contact position of the distal end that comes into contact with the ink roller. It is possible to provide a printing press cleaning device capable of shortening a cleaning time and improving an operation efficiency by efficient cleaning without increasing the supply amount of the cleaning solution.
