Abstract(s)
Ao longo dos últimos anos, a competitividade empresarial tem vindo a aumentar
drasticamente. Assim sendo, tornou-se necessário a criação de mecanismos de superação
em relação aos concorrentes. A simulação surge assim como um mecanismo “chave” de
resolução de grandes problemas, nomeadamente financeiros, de gestão de stocks, e
possivelmente mais importante, na ajuda ao processo de tomada de decisão tendo em conta
o ganho de tempo inerente aos projetos.
À medida que o tempo foi passando, as características dos simuladores foram sendo
melhoradas e especializadas, surgindo assim a simulação de robôs. Esta torna-se fulcral na
realização deste projeto.
A simulação de robôs caracteriza-se, não só mas principalmente, pela possibilidade de
efetuar a programação offline de robôs, a qual se diferencia da programação online no facto
de a primeira não usar o robô propriamente dito durante o desenvolvimento do programa.
A simulação de robôs possibilita também efetuar estudos e análises de layouts, durante a
fase projeto, sem a necessidade de aquisição prévia dos equipamentos para efetuar estes
testes. A otimização do layout de pintura de pneus, trabalho descrito nesta Dissertação,
recorre à utilização de um pacote de simulação de robôs, neste caso o ABB RobotStudio
para estudo da melhor solução a implementar na prática.
Inicialmente foram atendidas as informações de uma solução já existente, de modo a
estudar a melhor maneira de a otimizar. Foram propostos e analisados, junto da empresa
proponente deste trabalho, vários layouts, até à seleção de cinco que preenchiam os
requisitos e se mostraram mais promissores, tendo em conta o objetivo final – possibilitar
pintar 2000 pneus por hora – e o investimento inicial.
A solução apresentada como a mais viável, em resultado do estudo desenvolvido, tem em
conta a relação pneus pintados / investimento, apresentando, no entanto, um conjunto de
vantagens e desvantagens que também serão aqui abordadas. Tendo em conta o facto da
solução encontrada possibilitar pintar mais pneus do que o objetivo inicial proposto, isto poderá ser uma desvantagem caso a linha de produção seja expressamente de 2000 pneus
por hora, o que implicará o não funcionamento a 100% de todos os robôs nesse espaço de
tempo.
Over the past few years, business competitiveness has increased dramatically. Therefore, it became necessary the creation of mechanisms of resilience in relation to competitors. Simulation comes up like this, as a key mechanism for the resolution of major problems, namely financial, stock management, and possibly more important, aid the decisionmaking process taking into account the time gain inherent to projects. As time went by, simulators’ characteristics were being improved and specialized, resulting in the appearance of robot simulation applications. This becomes of crucial importance in the realization of this project. The simulation of robots is characterized, not only but mainly, for the possibility to perform the offline programming of robots, in which differs from online programming in the fact of the first do not use the robot itself during program development. The simulation of robots also allows performing studies and analyses of layouts, during the project phase, without the necessity of prior acquisition of equipment to perform these tests. Tire paint layout optimization, the work described in this Dissertation, appeals to the use of a robot simulation package, in this case the ABB RobotStudio, for the study of the best solution to implement in practice Initially it has been taken into account the former solution information in order to study the best way to optimize it. Were proposed and analyzed with the company several layouts, being selected five who meet the requirements and became the preferred layout, bearing in mind the ultimate goal – meet 2000 tires per hour – and the initial investment. The most viable solution takes into account the relation painted tires / investment, however presents its advantages and disadvantages. Considering the fact that the solution found to be able to paint more tires than the objective, this can be a disadvantage if the production line is expressly of 2000 tires per hour, which will entail non 100% operation of all the robots in that amount of time.
