RESEARCH ON PRODUCTIVITY IMPROVEMENT AND QUALITY CONTROL SYSTEM DEVELOPMENT FOR AUTOMATIC LINE STRIPE REMOVAL SYSTEM USING DRY ICE BLASTER

摘要

Recently, the construction industry beyond the traditional construction has increased automatic construction system because it is necessary to development for skilled labor shortage, productivity improvement, cost saving, quality improvement, safety concerns. However, current line stripe removing process both labor intensive and time consuming, employing a conventional grinding type manual machine. Out of manual tasks trigger various dangers either traffic accidents or explosion of harmful gas used for finalizing removing process. Therefore, the part of automatic system is that Automatic line stripe removing is necessary to improvement in construction field. This study develops the new concept of system using previously developed dry ice blaster to improve the productivity of line stripe removal system and includes the system development to remove residuals generated after removal processes perfectly. Also, a quality control system, for work efficiency after removing line stripe, will be developed by adding post-work quality control processes to improve the work efficiency through quality check by operator after work.
