Incremento del OEE en una inyectora de plástico basandose en la repotenciación del sistema de control

Abstract

It was designed and implemented a control system in order to improve OEE (Efficiency Global Team) of a plastic injection machine production company owners PARTIPLAST in Riobamba. The control system design was performed by TwidoSuite software for PLC, Studio Panel for HMI (Human Machine Interface), materials used as terminals, terminal blocks, relays and cables, a user manual is written for system management. The SFC programming and graphical programming TwidoSuite Panel Studio was performed by these connected elements Modbus TCP, programming design is based on the optimal management of temperatures, pressures and times, which can be manipulated and controlled by the sent via Modbus HMI and PLC which is responsible for handling each element of the injection machine, these parameters are crucial in the production process. Achieving an increase in production that is on a schedule from 9 am to 3 pm produced before 1200 shipowners while 800 were produced, the rate of defective owners if they fell before 120 owners now have 24 damaged. In conclusion, the machine OEE increased by 50%, loss of raw material is reduced by 80%. As a recommendation the operator of the machine must read the user manual.
