1. A paint production system with automatic self-adjustment of end product properties comprising:
a control center configured to send commands from a set of instructions in a computer program;
at least one continuous processing module; and
a volumetric dosing module comprising:
an image acquisition unit arranged above arms and configured to record activation of the arms by the commands received from the control center which, through digital image processing, is configured to perform confirmations of positioning and interlocking of the arms and the opening and closing of dosing valves, one each located on a free end of at least a portion of the arms;
wherein each of at least a portion of the arms further comprise a lever mechanism driven by a pneumatic actuator configured to move the respective arm by the commands received from the control center;
wherein the dosing valves are configured to release a specified amount of a component stored in a tank, by means of a dosing pump, into a tank of the continuous processing module;
wherein each continuous processing module comprises a rotary mechanism with an indexing unit driven by the center which, after activation, rotates a central shaft, to which radial arms rotated by gearmotors are coupled;
wherein at the free end of the radial arms the tank is positioned into which the specified amount of the component is dosed into the volumetric dosing module;
wherein the tank comprises an impeller shaft with a stirrer and a drain valve; and
wherein the tank is positioned sequentially:
in a mixing station comprising:
a mixing station pneumatic lifting mechanism with a mixing station motor and a mixing station sealing cap for positioning in an upper part of the tank; and
a mixing station traction pin fixed to the mixing station motor that connects the mixing station motor to the impeller shaft;
in a continuous property adjustment station comprising:
a continuous property adjustment station pneumatic lifting mechanism with a continuous property adjustment station motor and a continuous property adjustment station sealing cap for positioning in the upper part of the tank; and
a continuous property adjustment station traction pin fixed to the continuous property adjustment station motor connecting the continuous property adjustment station motor the homogenization impeller shaft and a material circulation pump in adjustment connected to the drain valve of the tank through an automatic coupling device for product flow for the tank, followed by data collection by the control center through a circuit containing a continuous line mixer, a multi-property meter with a Coriolis effect operating principle, a wet color measurement and adjustment unit and a three-way valve for material targeting in adjustment for return to the tank or for directing to a filling station when the product has met formulation specifications; and
in a cleaning station comprising:
a cleaning station pneumatic lifting mechanism with a cleaning station motor and a cleaning station sealing cap for positioning on the upper part of the tank; and
a cleaning station traction pin fixed to the cleaning station motor connecting the cleaning station motor to the impeller shaft and solvent injector nozzles arranged in the cleaning station sealing cap that receive the solvent through automatic valves of of cleaning manifolds, with the drain valve of the tank connected to a pneumatic pump for solvent removal.
