Diseño e implementación de un módulo didáctico para un proceso de corte transversal y transporte de papel controlado y supervisado desde un sistema scada diseño en Labview.

Abstract

This thesis project is based on a process of cutting steel sheets, in order to give greater ease of getting the raw material, has been used as material to cut the paper. The training module has the function of performing control of paper tension between the area of the paper reel and the pinch rollers, an ultrasonic sensor for it ensures that the consistent detection of the end of the roll is used, and that by means of a closed-loop controller determines the speed of the reel shaft. This will prevent the accumulation or lack of material. The incremental encoder wheel type installed, allow you to run the court once the programmable logic controller has reached the set length in the SCADA by the user indicated. The process ensures a continuous and stable flow of sheets to the system output by the speed control reel, wherein the paper tension remains constant. Further, the process has a proper synchronization between the primary and secondary pinch rollers, which meets the requirements for accurate and repeatable cut. The training module is designed to perform the cross-cutting role both in the manual mode and automatic. In manual mode is actuated by pushbuttons and automatic mode the PLC starts working, being out of operation manual operation mode.
