Title:
INK RECOVERY TUBE CLEANING APPARATUS FOR FLEXOGRAPHIC PRINTER
Document Type and Number:
Japanese Patent JP3901802
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To effectively clean the inside of an ink and cleaning liquid recovery tube by arranging an injection nozzle for blowing mixed fluid of high pressure containing the air and cleaning liquid to the tube disposed near an end pan, thereby shortening a recovery time of the ink and cleaning liquid.
SOLUTION: An injection nozzle 18 of mixed fluid provided at an upstream side of a recovery tube 1 is operated at a predetermined timing on the way of recovering cleaning liquid 3 via end pans 9a, 9b and the tubes 1a, 1b in a series of ink replacing operations. Thus, the fluid sent to the tube 1 in a high pressure fog state cleans and removes ink fixed to and retained on an inner wall surface of the tube 1 while sequentially colliding with the inner wall of the tube 1, and discharged together with the fluid into a bucket 14 of a downstream side. As a result, in the case of color changing at the time of order change, a fault of mixing old ink with ink of next order to contaminate the ink is eliminated to improve printing quality.
