Design and manufacture of automatic plastic valve welding machine

Abstract

Plastic welding method is a widely used technology for the welding of pressure and vacuum bags using plastic valves. Conducting this process with traditional methods creates disadvantages in terms of production speed, product quality and economical aspects. Today, assembly costs make up the majority of total production costs, manufacturers pay more attention to assembly automation and work in this direction in order to reduce costs, speed up the production process and increase efficiency. In this study, it is aimed to design and manufacture a single Automatic Valve Welding Machine that can do all of these operations and integrated automation system instead of cutting, punching and plastic welding process that can be performed with multiple machines and workers. In this context, a new automated machine was designed in 3 D, and engineering analyzes were carried out to manufacture a prototype. In design, the machine has been made suitable for developing technology by using PLC (Programming Logic Controller) and pneumatic system. In addition, static analyzes of the machine were made. With the inclusion of a production-specific automatic controlled plastic welding machine, manufacturing can be done faster, with higher quality, lower costs and less wastage compared to the traditional manufacturing process.
