Desenvolvimento de um protótipo de envasadora de líquidos semiautomática de baixo custo

Abstract

In any industrial sector, there is a constant search for improvements in the production process. Process automation has become the greatest ally, as it offers greater productivity in less time, reduces human work and reduces product waste. However, the high prices of equipment becomes a risky investment, since, according to SEBRAE, high investments without planning and lack of capital result in the bankruptcy of 80% of micro and small companies before completing 1 year, that is, , in its initial phase. Thus, the present work describes the development of a low-cost semi-automatic liquid filling machine, capable of filling pre-set quantities, using containers of different sizes. The project is aimed at improving the production process of small companies in the initial phase, in the cleaning materials sector that work with liquid products, such as disinfectants, alcohol, bleach and glass cleaner. We sought to use components that are easy to access and low cost, in order to make maintenance simple and make the prototype cheaper. Among the components used, the load cell stands out, consisting of resistive strain gauges coupled to a metallic structure which deforms according to the applied force, making it possible to measure quantities such as force and pressure. A prototype was built, which met the sufficient tolerances for the liquid filling process, in accordance with INMETRO Ordinance No. 248/2008, proving to be a great option, in view of the presented precision, agility in the filling process and the reduction of product waste.
