Projeto de um protótipo de um flambador automatizado de garrafas squeezes: estrutura mecânica

Abstract

This work was performed in accordance with the need for a manufacturer of gift ware that was having problems with the quality of flaming of the squeeze bottles, causing loss and rework. The squeeze bottles are made of polyethylene and before receiving the superficial print must pass into a superficial treatment, due the low superficial tension of that polymer, it is necessary to oxidize this surface, in order to improve the ink adhesion. The current process consists on a ring flamer machine, where have a flume coupled, the operator places one bottle at time to down and cross the ring flaming, so, this process depends of the presence of the operator for all the time, and for being repetitive work involving fire, cause ergonomic, accidents and physical risks. For the achievement of this work were consulted mainly articles and websites of manufacturers, for the purpose of have a better basement on the subject and the equipment. The choice of the materials took into consideration the location of the outfitter, prices and customer preferences, as in the case of the engine, stripe flaming and the thongs. This work has the objective to develop the design of the mechanical structure of a prototype of an automated flamer of squeeze bottles, aiming to solve the quality problem of the flaming. Two projects were proposed, the first one involving automatization and automation and second one, automatization only, that to be less expensive and less complex was chosen by the company. The project consists on a feeder, a supporter base, the carrier, the stripe flamer, safety devices and electrical parts. The last part that was commented is not subject of this work. Although studies show that cylindrical surfaces are best reated in aring flamer, the company demanded that the strip flamer must to be used, increasing the project cost. By automatization, this process will not depend on the operator, freeing of the repetitive work and providing an increased production.
