Automatización del conteo de pérdidas del proceso productivo de baldosas en la empresa Ecuatoriana de Cerámica C.A. utilizando un sistema de monitoreo de tiempo real.

Abstract

The current degree work consists in the automation of counting of losses of productive process of ceramic tiles in Ecuatoriana de Cerámica C.A Company, using a monitoring system of real time that will allow to the user the display of losses register in a production process. It was used a photoelectric sensors network E3F-R2N that send logical signals of a "1" if it detects the ceramic tile on the other hand a "0" to the digital inputs of Programmable Logical Controller (PLC) TWDLCAE40DRF that executes the control program and sends data through the Modbus network; for its display in the HMI screen that is found connected to the basis on data production lines, stages, dates and shifts. The data base is linked to a web page where is showed the losses register in each stage of the different production lines, the access to the registers was done through three types of users: manager, control and reports. It was implemented a control panel where it is found the PLC, the breaker that protects to the system, the power supply SITOP that is mandated of energizing to the devices, contactors to which are connected the sensors signals and the starting button. To analysing the register time of losses data by production processes, handily they were obtained 40 minutes; while to monitoring the data of automatic way they were obtained 9 minutes; showing a time saving of 31 minutes that means a 77% of improvement in time. With the project implementation it is optimized human resources and time; offering thereby a monitoring system truthful and efficient. It is recommended to explain not only to the operator about the system working; but also to the users about the running of web page in order to provide an optimum usage to the system.
