Nesta dissertação, é descrito um estudo realizado sobre um protótipo desenvolvido para efetuar a entrega automática de componentes plásticos numa máquina de gravação a laser e a sua respetiva recolha automática, após efetuada esta operação de gravação. Trata-se de uma solução mecânica automatizada que requer um operador para a sua respetiva programação, para o seu carregamento de componentes semiacabados na entrada deste equipamento e para a descarga dos respetivos componentes acabados. Mais concretamente, podemos defini-lo como um sistema de processo Buffer e que foi desenvolvido para ser carregado de forma modular, sendo que estas peças plásticas são montadas em paletes plásticas de dimensão standard de 600 mm x 600 mm e que poderão ser carregadas e descarregadas em cinco níveis. Para melhor definir este equipamento, o mesmo irá ser caracterizado em três áreas distintas que irão descrever o seu modo de funcionamento de uma forma mais simples e concisa.
A primeira zona é de alimentação, que pode ter até cinco tipos de componentes diferentes (cinco níveis com paletes de 600 mm x 600 mm) sendo que cada palete envolve um ciclo na máquina de gravação a laser. A segunda zona é denominada como a zona de picking das respetivas paletes e da entrega destas na máquina de gravação a laser. A terceira zona é a zona idêntica à primeira, mas nesta zona pretende-se a recolha das paletes da máquina de laser e a entrega destas nos cinco níveis que serão recolhidos posteriormente pelo operador.
Quanto ao seu modo operacional ou de funcionamento, este equipamento foi desenvolvido para trabalhar de forma automática ou de forma manual, sendo que será munido de um software desenvolvido por uma empresa externa (Sistemáquina), para controlar as operações de forma sequencial e para se poder efetuar manobras, de forma ajustada e manual. A máquina de gravação a laser também não estará neste âmbito de desenvolvimento sendo que esta será construída por uma empresa externa (Centi-Support). Contudo este equipamento é um culminar de diversas áreas e que se reflete numa solução única, resultante de uma combinação de tecnologias e empresas adaptadas a diversas realidades e soluções. Este equipamento irá resultar numa solução com inúmeras vantagens, sendo que as principais ir-se-ão refletir na diminuição dos tempos de operações, aumento de produtividade e diminuição de mão-de-obra.
In this dissertation, a study on a prototype developed to perform the automatic delivery of plastic components in a laser engraving machine and its respective automatic collection after this recording operation has been performed. It is na automated mechanical solution that requires an operator for its programming, for its loading of semi-finished components at the entrance of this equipment and for the discharge of its finished components. More specifically, it can be defined as a process system Buffer that was developed to be loaded in modular form, and the plastic parts are mounted on plastic pallets of standard size of 600 mm x 600 mm and can be loaded and unloaded in five levels. To better define this equipment I will characterize it in three different areas that will describe its mode of operation in a simpler and concise way. The first zone is the feed zone which can have up to five different component types (five levels with 600 mm x 600 mm pallets) and each pallet involves a cycle in the laser engraving machine. The second zone is referred to as the picking zone of the respective pallets and the delivery of these in the laser engraving machine. The third zone is identical to the first one, but in this zone we will have to pick up the pallets of the laser machine and the delivery of these in the five levels that will be collected later by the operator. In terms of its operational or operating mode, this equipment was developed to work automatically or manually and will be equipped with software developed by na external company (Sistemáquina), to control operations sequentially and to be able to perform maneuvers of adjusted and manual form. The laser engraving machine is also not in our scope of development and it will be built by an external company (CentiSupport). However, this equipment is a culmination of several areas and is reflected in a unique solution, resulting from a combination of technologies and companies adapted to different realities and solutions. This equipment will result in a solution with numerous advantages, the main ones being reflected in the reduction of the times of operations, increase of productivity and decrease of workmanship.
