DEVICE FOR CLEANING PNEUMATIC LINE FOR SELF-HARDENING MATERIAL

摘要

PROBLEM TO BE SOLVED: To reduce plugging of pneumatic lines effectively with a simple structure by effectively cleaning and removing residues of a self-hardening material in the pneumatic lines of a cleaning device equipped with at least 3 or more pneumatic lines for self-hardening materials. SOLUTION: At least 3 or more pneumatic lines for the self-hardening material are connected respectively with supply lines of cleaning water, and the each line is equipped with a switching valve capable of controlling opening or closing of the line. The each line is connected with a main line of the cleaning water by a connecting fixture installed on the upstream side of the position where the switching valve is located. On the upstream side of the position where the connecting fixture is located, an open/close valve capable of controlling opening or closing of the main line of the cleaning water is installed.
