Title:
ROTARY ATOMIZING TYPE COATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/154622
Kind Code:
A1
Abstract:
Provided is a rotary atomizing type coating machine that can reliably prevent cleaning agent leaks from a cleaning nozzle during coating and prevent occurrences of coating malfunctions caused thereby. This rotary atomizing type coating machine 1 is provided with a cleaning fluid supply pathway 21 for supplying the cleaning agent and air to a cleaning nozzle 26 for a rotary atomizing head 14, a check valve 31, and the like. The check valve 31 is disposed on the upstream side in the immediate vicinity of the cleaning nozzle 26 so as to close the cleaning fluid supply pathway 21 along the way when not cleaning. The check valve 31 has a valve main body 32, a valve seat 33, and a biasing means 34. The biasing means 34 biases the valve main body 32 on the valve seat 33 side in opposition to forward flow of the cleaning fluid. The biasing force applied by the biasing means 34 is set smaller than the supply pressure for the cleaning fluid during cleaning. A residual pressure reducing mechanism Z1 is provided for reducing residual pressure in the area on the upstream side of the check valve 31 in the cleaning fluid supply pathway 21.
