Diseño e implementación de una máquina insertadora de liners para automatizar el proceso de enlainado en la producción de tapas de 28, 38 y 48 milímetros de diámetro en la empresa Valdisplast Cia. Ltda.

Abstract

The current degree work consisted in the development of a machine capable of automating the process of inserting liners in plastic caps with diameters of 28mm, 38mm and 48mm. the set of caps and liners used for this work corresponds to the line of products offered by the company Valdisplast Cia. Ltda., which is addressed to the production and sale of plastic containers and accessories for multiple industries around the country. This work aims to present an alternative to the constant problems that the company is subjected to in the lining process of its caps due to the growing demand for these products, requiring multiple workers to meet delivery times and even extending working hours. A design capable of offering flexibility to the machine was proposed to work with all the variants of caps and liners, both at the material level and in the geometric aspect. In the implementation, the choice of materials that avoid contamination in the elements that are part of the process was taken care of, and the automation plan was established through a programmable logic controller that governs a pneumatic system; defining their actions from the information received from sensors and through a Human-Machine Interface. Functional tests were carried out on the existing machine based on information related to the existing demand in the company, in the tests the production times and effectiveness in the lining of caps were determined. Finally, some financial consideration related to the investment of the work and its scope in general were reviewed.
