Diseño y construcción de una máquina bobinadora de precisión para rafia de polipropileno en la Empresa HIPLAS.

Abstract

¨HIPLAS¨, Specialized Plastic Thread, is a company that works in the manufacture of strings and plastic cords which are obtained by extracting polypropylene, after passing it through a heating furnace changing its physical properties and after passing through a train stretching and finally get raffia, which it is wound continuously and properly distributed, it can follow the following processes such as the twisted, braided and packaging, resulting the final product for commercialization. The factory has winding machines with a load capacity of 5 kg, these coils raffia continuously fed to different machines of the following processes, therefore more coils are needed for the same article producing a big quantity of joins or mooring, it means that they do not have enough volume charge. Because of the need to improve the productive capacity of the winding machine was raised to increase the load to 20 kg, and it is made a precision tissue helping the manufactured coil that has a cylindrical shape and uniform distribution reaching an adequate load capacity, reducing the joints and improving operational performance and functionality. The development of the improvement of it is estimated by mechanic study of elements of the winding machine, analyzing the parameters required to design and build, selecting the best choice to be made by developing assays to determine properties of the tape raffia as the breaking force, selection of mechanical elements, power and control. The successful design and construction of precision winding machine load increase productivity by 75%, reducing significantly the problem of food, and the marked improvement of the quality of the final product with acceptable efficiency.
