Diseño de un sistema de automatización para el horno de curado de pintura electrostática de la Compañía PROIND S.A.S

Abstract

Currently, in the facilities of the company PROIND S.A.S. (a company dedicated to offer solutions in architecture and structural design projects, furniture for exhibition, storage or interior design, etc.) is installed an electrostatic painting booth and a curing oven for the final treatment that is performed for this type of process. This equipment is indispensable both for the final finishing of the structures used in the company's different projects and for the painting service provided to third parties when requested by them. The current procedure is as follows: as a first step the powder paint is applied inside a cabin that together with a cyclone for the reception of particulate material (in this case the powder residue of the paint) controls the segregation of the particulate material into the atmosphere that was generated by the application of the paint, after this, the structure or painted pieces as described in the first step are placed either on a fixed support or on hanging supports to proceed to introduce them into the oven for curing through a heating process with gas burners, but it is here where it will enter to optimize the entire painting process since the industrial control applied to the equipment is practically null, its operation is empirical and is limited to an on and off by simply flipping an ON/OFF switch. As main objective within the first stage of automation of the general process, it is intended to design an automation system for the curing oven where the operating conditions of the same are improved, implementing a programmable logic controller (PLC) and a human-machine interface (HMI), where through the latter can visualize and control the variables of the process included in the first stage of the project.
