Diseño y construcción de una máquina semiautomática de serigrafía para piezas cilíndricas y cónicas entre 20MM A 200MM

Abstract

The advertising sector in the country has experienced a significant increase in recent decades as each company tries to promote itself with eye-catching elements. Still, there is a problem with the number of screen-printed products due to the demand in production and work fatigue that can cause manual screen-printing machine operators and the use of additional personnel for the process. Therefore, the research's objective was to design and construct a semi-automatic screen printing machine for cylindrical and conical objects that improves the screen printing process in total production, reduces additional operators, and improves precision. The methodology used in the research was based on the German standard VDI 2221, which shows a systematic approach used to receive requirements and demands, as well as the choice of optimal alternative taking into account economic and theoretical aspects, once the elements that fulfill the inherent functions of the system, kinematic and dynamic analyzes were carried out that verified the paths of moving parts with their respective speed. As a result of the project, it was possible to build and install the screen printing machine with a high production capacity, even reaching 1000 pieces/h, optimizing time and reducing production costs. In this framework, it is concluded that the screen printing mechanism manages to meet the demand for products by ensuring the quality of the final products, reducing the number of personnel to only one operator per machine, and counteracting ergonomic problems caused by repetitive movements.
