Design and Start-Up of an Automatic Paint Mixer

Abstract In daily life, is very common to witness scenes in which it is necessary to obtain different ranges of colors in the paintings that are used either with water or oil. This range of colors comes from the fusion and homogenization of primary colors or tones. Frequently, the process of mixing and dosing are carried out by people who, by trial and error, determine the color desired by the user. Then, the quality and precision of the paint is affected and generate customer dissatisfaction, claims, waste, and low productivity. This article shows the design and start up process of an automatic mixer prototype that doses and mixes paint to create complex color shades by implementing a human-machine interface and a control stage and verification. Also, the results of this investigation shows the engineering process carried out to obtain a prototype of a functional, automatic, exact mixing machine and a homogenous and quality product that meets the customer’s requirements. Improvements that will can do and future work are included too.
