การลดเวลาในการปรับตั้งลูกอัดสำหรับการผลิตไม้ฝาสังเคราะห์ / โกสินทร์ เจริญวรเกียรติ = Time reduction for forming roll set up in artificial wood plank manufacturing / Kosin Charoenvorakeat
The objective of this research is to reduce the time of forming roll set up process in the artificial wood plank manufacturing . This process consumes much time more than other processes because of its unnecessary or inefficient steps leading to time and resource losses. The search for this cause of unnecessary or inefficient time in the set up process is based on the knowledge of time study , working process study and fishbone graph after that improvement this process with adaptive technique called “ SMED (Single Minute Exchange of Die) ’’ . In process is change internal activity to external activity leading to reduce 54 minutes and improvement process can be classified in 6 steps . Improve internal activity 5 steps and improve external activity 1 step .(1) Unnecessary set up activities are eliminated leading to reduce 20 minutes. (2) Improve preparation activity to external activity leading to reduce 13 minutes. (3) Improve set up activity to external activity leading to reduce 7 minutes. (4) Improve adjustment activity to external activity leading to reduce 8 minutes. (5) Improve overall internal set up activity leading to reduce 33 minutes. (6) Improve overall external set up activity leading to reduce 20 minutes by not include internal set up time . After improvement the set up time has reduced 135 minutes . Finally of 6 machines in this research , the set up time has reduced from 300.40 minutes to 165.20 minutes per time or about 45.01% .
