Implementación de una estación de fijación y prensado con un PLC para el laboratorio de control y automatización de procesos industriales de la Facultad de Mecánica de la ESPOCH.

Abstract

The dimensioning of a fixation and pressing module has been carried out in CAD software due to the need of didactic modules in the faculty of mechanics of the ESPOCH, for obtaining the lists of materials and simulation of basic movements. The design incorporates a sequence for the positioning of two burettes, its transport, and later pressed. For the pressing process it was used an analog pressure sensor, a proportional pressure actuator and the pneumatic muscle like system to be controlled. Control parameters as the SETPOINT communicate via Ethernet network from the HMI; once the SETPOINT and the pressure of feedback are equal the break-even point is reached. Both the SETPOINT and the pressure of feedback appear in real-time in the HMI. To facilitate the maintenance tasks each of the actuators of the training module can be activated manually, as well as the system of pressing can be activated from the HMI with any pressure inside a definite status of pressure (0-6 bar). The security services implemented were established by means of programming, in the case of a pressure value out of the established limits, the PID regulator comes to turn off automatically. A manual of preventive and corrective maintenance was made with frequencies according to the use of didactic modules, finally cost analysis allowed to know the economic value of fixing and pressing station.
