Abstract(s)
O fabrico de vestuário é uma atividade que se desenvolve em Portugal há várias décadas.
Existem marcas de vestuário com reconhecimento a nível mundial que são de origem portuguesa.
Para se conseguir qualidade é necessário inovar e automatizar determinados processos, de forma a
aumentar produtividades e reduzir erros devido à mão de obra de tarefas intensivas. Na empresa
Portuguesa Henrique Camões, com uma vasta experiência ligada a equipamentos de fabrico têxtil,
nasceu a ideia de projetar um protótipo de um equipamento automatizado para o fabrico de colarinhos
e punhos, com a finalidade de verificar a sua viabilidade a nível funcional.
Este trabalho teve assim por base a necessidade de efetuar um projeto sobre um equipamento
capaz de costurar e cortar colarinhos e punhos, a serem aplicados em peças de vestuário. Inicialmente
foi efetuado um estudo prévio de levantamento de equipamentos já existentes para fins semelhantes.
Foi então necessário idealizar um equipamento capaz de responder às expectativas e exigências por
parte do cliente. Após os esboços iniciais, onde foram definidos os tipos de mecanismos e formas de
funcionamento dos diferentes sistemas em função dos movimentos e ações pretendidas e a estrutura
do equipamento, estes sistemas foram otimizados por forma a se obter como resultado final um
equipamento funcional. Foi também projetado o esquema pneumático e Grafcet de funcionamento
do equipamento. Como auxiliares do projeto, apresentam-se a lista de componentes e de processos
de fabrico, bem como os desenhos de pormenor de todos os componentes integrantes da estrutura.
O resultado final é um conjunto de ideias e soluções possíveis de aplicar num equipamento
deste tipo. De facto, a solução proposta é uma possibilidade viável para um equipamento
automatizado para costura e corte de colarinhos e punhos.
Clothing manufacturing is an activity that takes place in Portugal for several decades. Several clothing brands with worldwide recognition are of Portuguese origin. To achieve quality, it is necessary to innovate and automate certain processes, in order to increase productivity and reduce errors due to labor intensive tasks. In the Portuguese company Henrique Camões, which has extensive experience in the design of textile manufacturing equipment, an idea was born to design a prototype of an automated equipment for the manufacture of collars and cuffs, in order to verify its functional viability. This study was thus based on the need to design a machine able to sew and cut collars and cuffs, to be applied on clothing. Initially, a previous survey study for similar purpose existing equipment was performed. Then, it was necessary to devise an equipment able to meet the expectations and requirements of the client. After the initial sketches, in which the types of mechanisms and the desired functions of the different systems were defined as a function of the intended movements and actions and the equipment structure, these systems have been optimized to obtain a functional unit as the final result. The pneumatic scheme and Grafcet of operation of the equipment were also designed. As auxiliary of the project, the list of components and manufacturing processes, as well as detailed plans of all integral components of the structure, were presented. The end result is a set of possible ideas and solutions to apply in equipments of this type. In fact, the proposed solution is a viable possibility for an automated equipment for sewing and cutting collars and cuffs.
