Development of Automatic Corner Stone Trimming Working Machine for Boundary Stones

Abstract

Stones are major materials for various civil engineering works and architectural construction areas and various kinds of stones are being used in construction sites and those areas are also very diverse. Even though the size of domestic stone market size is currently increasing, production volume cannot meet the demand because the production method is still highly dependent on manual work. In addition, as China is rising as the center of world stone market which emphasized the strong price competitiveness, imports from China are currently increasing because China is gradually securing the quality competitiveness as well. This seems because the quality of Chinese stones does not fall behind than the quality of domestic stones and in order to recover this situation, it is considered important to maximize the productivity of domestic stone working companies through the automation of production environment and to secure the price competitiveness through quality equalization to deal with low labor costs which China is emphasizing as their strength. Based on these reasons, this development was conducted and tried to secure the competitiveness of stone working by developing automatic control technology and stone working technology using air pressure and PLC, preventing risk factors and environmental problems caused by manual work in stone working site, removing working risk factors through automation and reducing dust and noise. And accordingly, automatic corner stone trimming working machine for boundary stones was developed, and production environments were improved and productivity could be maximized through the automation of manpower dependent works.
