High-speed automatic line for producing paints

An automatic line for producing paints, comprising:

• a first dosing unit configured to form in each of a plurality of empty retail containers a first base including at least one first base dose;
• at least one coloring unit configured to dispense at least one dose of colorant into the retail containers coming from said first dosing unit via a transport system and containing said first base;
• a second dosing unit configured to form a second base including at least one second base dose in the retail containers coming from said at least one coloring unit via the transport system and containing said first base and said at least one dose of colorant;
• at least one closing unit configured to apply closing lids to respective retail containers to form closed retail containers;
• at least one mixing unit configured to agitate said closed retail containers and to mix said first and second bases and said at least one dose of colorant;
• and
• each of the first and second dosing units including a plurality of volumetric dosing devices, each volumetric dosing device including:
• an accumulation tank;
• a dosing tank, wherein the accumulation tank is positioned above the dosing tank;
• and
• a dispensing cylinder in separate fluid communications with the accumulation tank and the dosing tank, the dispensing cylinder having an outlet for dispensing dosages and being positioned below the dosing tank and including a dispensing piston selectively actuatable to i) place the accumulation tank and dosing tank in fluid communication with each other, and ii) place the dosing tank in fluid communication with the outlet of the dispensing cylinder for dispensing one of the at least first base dose and the at least second base dose into the retail containers.
