Diseño de un sistema automatizado de lavado por aspersión para piezas a pintar con recubrimiento electrostático en la Empresa Creación Pintura y Diseño S.A.S

Abstract

Painting and Design Creation S.A.S is a company dedicated to paint metal parts, which requires processes that involve chemical baths at specific temperatures and times. Before being impregnated with powder paint, there is a phase of enlistment or cleaning, once this procedure is performed, the pieces are impregnated with powder paint and then passed to an oven in which the polymerization is carried out. All these processes are carried out manually, and the most critical is the one of enlistment or washing, since when a piece is poorly washed the following processes are completely canceled, for this reason our proposal focuses on the design of an automated washing system for pieces, which would replace the first process, improving the quality of parts washing and decreasing the operation times in this phase. The automated washing system for parts is composed of an electromechanical parts transport system that moves the parts through chains and devices from the feeding place through washing booths to the paint booths, in the washing the cleaning is carried out of the pieces by aspersion, thanks to a network of pipes arranged in 4 phases; first pre-rinse, phosphatized, second pre-rinse and passivated, at the end of this tour the pieces are transported to the paint booths mechanically avoiding any type of contamination before being painted. The transport system works in a continuous way thanks to a control circuit, this circuit also controls the system of pumping and heating of the fluids. It should be noted that apart from the washing of the pieces, the system also assumes the transportation of the pieces from the feeding to the painting, avoiding unnecessary efforts and injuries on the part of the operators, thus guaranteeing an online process. In the market there are complex and expensive automatic systems that would be inaccessible to medium-sized companies, our less complex design based on cost reduction is a solution for the company Pintura Pintura y Diseño S.A.S which would overcome its problems of quality and production obtaining greater benefit.
