A realizaĆ§Ć£o desta Tese/DissertaĆ§Ć£o tem como objectivo o estudo e implementaĆ§Ć£o piloto de um Sistema de SupervisĆ£o e AquisiĆ§Ć£o de dados (SCADA) na Swedwood Portugal, na qual exerƧo as funƧƵes de Engenheiro de Processo nas linhas de montagem de mobiliĆ”rio.
Foi efectuado um estudo das necessidades da empresa relativamente Ć s melhorias dos processos das linhas de montagem, com o intuito de melhorar a montagem do semi-produto, a nĆvel de qualidade das matĆ©rias-primas, operaĆ§Ć£o e desempenho de equipamentos. Chegou-se Ć conclusĆ£o que existe uma grande necessidade de controlar a qualidade das matĆ©rias-primas utilizadas na construĆ§Ć£o do semi-produto em tempo real, de modo a que seja possĆvel diminuir a complexidade na recolha atempada de amostras por parte dos elementos de operaĆ§Ć£o e diminuir o atraso da entrega de resultados das amostras por parte do laboratĆ³rio.
A colagem Ć© um elemento crĆtico na montagem do semi-produto, devido Ć s variaƧƵes de viscosidade da cola, consequĆŖncia das variaƧƵes climatĆ©ricas a que foi sujeita, desde a saĆda do fornecedor atĆ© Ć sua utilizaĆ§Ć£o nas linhas de montagem.
Para tal concebeu-se uma soluĆ§Ć£o para dar uma resposta mais rĆ”pida no controlo de qualidade da cola Ć base de acetato de polivinil (PVAC), ou seja, a implementaĆ§Ć£o piloto de um sistema SCADA na sala de colas, de modo a que haja um controlo a nĆvel de temperatura e humidade, controlo de viscosidade em tempo real e controlo do nĆvel da cola na cuba, fazendo com que haja sĆ³ uma supervisĆ£o por parte dos elementos de operaĆ§Ć£o.
Optou-se por um conjunto de hardware e software da SIMATIC desenvolvido pela Siemens, para elaboraĆ§Ć£o da programaĆ§Ć£o e desenvolvimento da Interface Homem MĆ”quina (HMI).
The realization of this Thesis/Dissertation has the goal to study and implement a pilot Supervisory Control and Data Acquisition (SCADA) in Swedwood Portugal, in which I perform the functions of Process Engineer in the assembly lines of furniture. It was realized a study of company needs for the processes improvements in the assembly lines, in order to improve the assembly of semi-product, raw material quality, operation and equipment performance. This study reached the conclusion that there is the need to control the quality of raw materials that are used in the assembly of semi-product in real time, so that it is possible to reduce the complexity in the timely collection of samples by the operating elements and decrease the delay in delivery of results of the samples by the laboratory. The glue is a critical element in the assembly of semi-product, due to changes in viscosity, as a consequence of the variations in the weather conditions to which it was subjected, since the departure of the supplier until being ready to use on the assembly lines. With this purpose, a solution was conceived to provide a faster response in the quality control of the glue, based on polyvinyl acetate (PVAC), ie, the pilot implementation of a SCADA system in the glue room, so that there is a control of temperature and humidity, real time viscosity control and level control of the glue in its container, making possible only one supervision by the operating elements. We chose a set of SIMATIC hardware and software developed by Siemens, for the implementation of the programming and development of Human Machine Interface (HMI).
