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. |
