Ergonomics Assessment in Improving the Work for the Winding Process

Abstract

The purpose of this research is to study the ergonomics problems in the winding process of the Ban Rong Yang weaving woman group and to advise the way of improvement by using RULA techniques. The results show that the performances before adjusting the weft and warp winding process are 3 and 4, respectively. It means that the winding process may need to redesign. According to the thread winding process, the spinning of arms and wrists will be used repeatedly. It may cause body aches. Thus, this study will design and create the drum winding machine drive by AC motor as the primary power source to rotate the drum in order to pull the thread from the reciprocal to the cylinder. The results of this study show that the performance after adjustment turns to 2. It means the development process can be accepted. The result of the improvement of working methods in spinning and threading process is effective at 1.83 and 1.48 times of work before the improvement.
