O presente projeto de tese de mestrado com o tema āAutomatizaĆ§Ć£o do Pro cesso Manual de Pesagem de Pigmentosā foi desenvolvido em contexto industrial,
na empresa Continental Mabor - IndĆŗstria de Pneus (CMIP), localizada em Lou sado. Esta dissertaĆ§Ć£o apresenta, no seu conteĆŗdo, uma anĆ”lise do processo atual de
pesagem de pigmentos, um estudo e projeto de uma soluĆ§Ć£o para automatizaĆ§Ć£o do
respetivo processo, tendo sido encontradas diferentes soluƧƵes possĆveis. Foi ainda
implementado um robĆ“ colaborativo para possibilitar testar uma parte da soluĆ§Ć£o
idealizada.
O projeto iniciou com a identificaĆ§Ć£o e estudo do processo atual de pesagem dos
pigmentos que, Ć data, consistia num processo totalmente manual de manipulaĆ§Ć£o
dos pigmentos e dos sacos de plƔstico utilizados para o seu transporte. O processo
em questĆ£o foi caraterizado, tendo sido descrito cada etapa do processo, as ferra mentas e o espaƧo de trabalho existente. Foram tambĆ©m listados e caraterizados
os pigmentos utilizados no processo. AlƩm disso, foi realizado um estudo, obtendo
dados representativos do processo atual e que servem de base para o projeto da
soluĆ§Ć£o futura.
ApĆ³s uma primeira fase de reconhecimento e caraterizaĆ§Ć£o do processo atual,
foram propostos os requisitos necessĆ”rios para cada equipamento da soluĆ§Ć£o futura
idealizada. Este projeto acabou por estar dividido em duas partes: o doseamento
dos pigmentos e a manipulaĆ§Ć£o dos sacos de plĆ”stico. Para a primeira parte, jĆ”
existia um conceito prƩ-identificado, onde apenas foi necessƔrio efetuar alguns ajustes ao conceito inicial e realizar a escolha dos componentes necessƔrios, conforme os
requisitos propostos inicialmente. ApĆ³s essa escolha, foi implementado um primeiro
protĆ³tipo funcional do conceito, no qual foram realizados alguns testes de desempenho. AtravĆ©s destes testes, foi possĆvel obter os primeiros dados do possĆvel sistema
de doseamento, mais especificamente, dos tempos de ciclo do robƓ colaborativo. Na
segunda parte, foi necessƔrio investigar quais as soluƧƵes presentes no mercado que
se enquadravam melhor nos requisitos estabelecidos. Foram encontradas trĆŖs tecnologias diferentes, tendo sido projetado uma soluĆ§Ć£o com cada tecnologia. Para alĆ©m
disso, foi preparada uma descriĆ§Ć£o de das soluƧƵes, com as vantagens e desvantagens,
e o respetivo orƧamento necessĆ”rio para a sua implementaĆ§Ć£o.
Em forma de conclusĆ£o, os resultados obtidos dos testes realizados apresentam
um tempo de ciclo elevado, em relaĆ§Ć£o do processo atual. PorĆ©m, em termos deergonomia e bem-estar, esta soluĆ§Ć£o torna todo o processo e a Ć”rea de trabalho
associada mais acessĆvel e adequada para a presenƧa do humano. Esta automaĆ§Ć£o
do processo afasta os operadores do trabalho duro e repetitivo, passando-os para a
tarefa de supervisĆ£o e/ou tarefas extras.
This masterās thesis project, entitled āAutomatization of the Manual Pigment Weighing Processā, was carried out in an industrial context, at the company CMIP, located in Lousado. The content of this dissertation includes an analysis of the current pigment weighing process, a study and design of a solution to automate the process, and different possible solutions were found. A collaborative robot was also implemented to test part of the idealized solution. The project began by identifying and studying the current pigment weighing process, which at the time consisted of a completely manual process of handling the pigments and the plastic bags used to transport them. The process in question was characterized, describing each stage of the process, the tools and the existing workspace. The pigments used in the process were also listed and characterized. In addition, a study was carried out, obtaining data representative of the current process and serving as a basis for the design of the future solution. After a first phase of recognizing and characterizing the current process, the necessary requirements were proposed for each piece of equipment in the idealized future solution. This project ended up being divided into two parts: the dosing of pigments and the handling of plastic bags. For the first part, a pre-identified concept already existed, where it was only necessary to make some adjustments to the initial concept and choose the necessary components, according to the requirements initially proposed. After this choice, a first functional prototype of the concept was implemented, in which some performance tests were carried out. Through these tests, it was possible to obtain the first data on the possible dosing system, more specifically, the cycle times of the collaborative robot. In the second part, it was necessary to investigate which solutions on the market best met the established requirements. Three different technologies were found and a solution was designed with each technology. In addition, a description of the solutions was prepared, with the advantages and disadvantages, and the respective budget required for their implementation. In conclusion, the results obtained from the tests carried out show a high cycle time compared to the current process. However, in terms of ergonomics and wellbeing, this solution makes the entire process and the associated work area more accessible and suitable for human presence. This automation of the process takes operators away from hard, repetitive work and into supervisory and/or extra tasks
