A system which continuously automatically produces paint, particularly for
automotive applications, includes tanks of raw materials which are
constructed to supply resins, paint concentrates, paint additives, and
paint solvents in a fully automated and continuous matter, which results
in the production of paints substantially without manual intervention. The
system includes a main circulation system which receives the metered
dosages of raw materials automatically, collects the raw materials in
mixing tanks and which includes outlet pipes which direct the mixture
towards a main mixer. The paint is directed to a storage tank, with a
portion of the paint being diverted to a control cell which samples the
paint and analyzes it and derives from it parametric information which is
compared to prestored criteria and which serves to adjust the properties
of the ultimately obtained paint as to color, coverage and viscosity. An
internally provided cleaning system uses pressurized nitrogen to push
remnants of the paint from the pipes and associated equipment at the
conclusion of the production of a given paint to prepare the system for
the production of a paint having different characteristics, ingredients,
and raw materials.
