Automatización de la máquina flejadora para puertas enrollables de la empresa Industrias Metálicas Vilema del cantón Guano.

Abstract

The main objective of the present degree work is to automate the strapping machine for rolling doors of the company Industrias Metálicas Vilema of canton Guano in order to improve the production process, reducing the times and costs of production. For the analysis of the initial situation process diagrams, a tool for the study of methods and times are used. The design of the automated system is carried out by means of the appropriate selection of elements that allow the automatic cutting of the straps for the rolling door. In the design, the structure and components of the system are established, then the CAD modeling and the Static Analysis are performed. As for the results, in the initial situation analysis, a production time of 5,22 hours was determined with a strapping time of 1,41 hours which is high compared to the other operations due to the fact that it is a repetitive work because 45 strips have to be manually elaborated, for this reason, the need was seen to implement this process in order to raise the productivity of 67,05%. An automated system based on a programmable logic controller (PLC) was implemented, which controls the supply and automatic cutting of the strapping in the strapping machine, which reduced the operator's operating time of 1,19 hours, reduced the costs of production 2,97 dollars and increased productivity from 67,05% al 86,55%. The automation of the strapping machine replaces the tasks performed by the operator, which is why it is recommended to use their labor in other activities required by the company in order to improve productivity.
