Estudio e Implementación de un Sistema de Automatización para el Incremento del OEE en un Pulpo Serigráfico.

Abstract

A performed study and an automation system were implemented to improve the Overall Equipment Effectiveness (OEE) of a manual serigraphic octopus in the XIAN Company of Ambato city. The scientific method allowed us to make the observation process acquiring previous data to automation and they determine the parameters to improve. They got as a result a measurement OEE manual Serigraphic octopus of 25.04%. After, the following materials were analyzed and selected for their implementation: rotary and linear bearings, structured metal profile, electro valves and pneumatic pistons, throttle valves, Programmable Logic Controller (PLC) with a module output expansion, magnetic and mechanical position sensors, relays, and control switcher. For programing the control system the TIA Portal platform was used; NI OPC Server software allowed us to establish communication between the PLC and Man-Machine Interface (HMI), that performs the operations control system and register of production, it was developed in programing software LabView. Afterwards, the implementation of the automated system was experimented with different configurations of the pneumatic actuators and programmable logic of PLC, an OEE = 68.48% was obtained as result. In conclusion, the machine was placed within an acceptable range of efficiency; an increase of 43.44% was achieved. It is recommended to increase the number of sensors for monitoring and individualized control of each station serigraphic octopus.
