Application of TRIZ to Improve the Material Handling and Productivity in a Screw-Packaging Factory

摘要

Although the screw is small, it is really basic and necessary in our lives. It is an integral part of almost all the industrial products. This study uses a systematic and innovative approach, TRIZ (Teoriya Resheniya Izobreatatelskikh Zadatch), to solve the layout problems of an existing screw-packaging factory. The work has modified the layout of the factory and applied a closed-loop-type rail-guided vehicle system (RGVS) with a forklift device. The automatic material handling system has replaced some forklift trucks. The advantage of this modification is an increase in production output from 48 ton/day to 96 ton/day, reducing the number of forklift trucks from six sets to three sets and increasing the throughput of material handling from 80 pallet/h to 160 pallet/h. In addition, the results also improve the industrial safety and make the environment more eco-friendly.
