Abstract
The objective of this paper is to create an ergonomic automatic controlled system based on a methodology used by a large-sized automotive company that point some criteria to evaluate working spots analyzing the worker movements during the takt. It involves the Project and Management area with planning, management and automation studies, which has great importance to companies bringing continuous improvements due to quality increase, volume increase, cost reduction and standard routines operation. This methodology evaluates industrial operational stations and classifies them as good, medium or bad work condition regarding ergonomics topic, in order to avoid health issues to the worker. Due to that, this study aims at worker position evaluation during factory routines instantaneously, in such a way that good ergonomic conditions and worker comfort are preserved and labor risk minimized. Therefore, an operator vestment was developed with mechanical and electronic devices combined also using a sort of different sensors to acquire information like body/member position, and that indicate bad ergonomic situations in real time. Movements analyzed are the main angles of the human body, loads carried, forces needed, heights, distances and positions, in the moment of tasks execution. There is a lack of ergonomic evaluation solutions, for industrial companies, even more automatic ones, which work with several manual operations but without continuous monitoring of working tasks. To validate this system, preliminary tests were conducted at the university, collecting the results and making improvements on the device in order to favor the operation and avoid normal routine alteration. At the end, results are compared with the methodology and the efficiency of the system is noted. For next steps, this optimized system can be used in any manual industrial operation.
