Aplicación del diseño concurrente de una máquina briquetadora.

Abstract

The present work has the purpose of designing a briquetting machine through the integrative methodology of the concurrent engineering for the production of sawdust briquettes and chip in the company DECOSA CIA LTDA, located in the city of Quito. In order to comply with the objective, the deductive and experimental research methods were incorporated, which allowed the design of the fundamental parts in witch to work for a concurrent design, so that the conceptual design was developed in the witch establishes the initial specifications required by the user regarding the specifications of the machine. The tool that was used for the developed of this stage was the Quality Function Deployment (QFD), which involved the construction of the quality house matrix, this matrix helped to control and measure the design parameters. For the functional design, the functional analysis was used, which allowed to establish 5 modules that are part of the briquetting machine, with each one of its functions, the solutions alternatives that were determined for each module were evaluated by the method of the weighted criteria, which allowed to establish the best alternative conceptual and functional design. In the phase of the details design the materials were defined and each of the modules of the machine was dimensions with the help of the Solidwork tool, a pressure of 30 Mpa was determined for the compaction of the material and a hardness of 90%. To complete de detail phase, the SIEMENS S7-200 PLC and rotary vane level sensors were selected, which help the automation proposal of the briquetting machine. With the implementation of this methodology it was possible to reduce development times in the design and created a machine that through the implementation, can be competitive in the market. It is recommended to analyze and study the possibility of the implementation of the briquette machine in the timber sectors, especially in the factories that present a high degree af accumulation of sawdust and chip waste.
