Abstract
This cleaning system is designed to automated and minimize or eliminate the excessive amount of manpower associated with other suction processes. It is a combination of paint recovery, and flushing methods in a automated manner. It is designed to minimize the paint lost as a result of color changing of circulation systems, as well as minimize the associated time and solvents used to in the cleaning process. This is accomplished by inserting a first pig into the circ system at the end of a desired painting cycle to push out the paint and propelling the first pig through the system using a solvent. The location of the first pig is then sensed and the first pig collected from the system. A second pig is injected into the system to separate the solvent from a new cycle of paint.
