[[alternative]]Study of Applying Material Tension Controller on Roller Process Equipments

碩士電機工程學系[[abstract]]材料張力控制應用隨著電子科技與包裝產業之蓬勃發展，使用的越來越多也越來越廣泛，尤其是圓捲型材料因重複多次加工之速度與精度要求越來越高而更顯出其重要性。本研究主要探討藉由增加張力控制機制來降低輪轉設備於材料加工時，因材料特性（如延展性、伸縮彈性等）或設備元件加工精度與傳動導輪圓周誤差所造成之各加工站間的速度累積誤差，致使加工材料被拉扯或擠壓變形，進而影響到加工品質。為解決前述問題，本研究在兩傳動導輪機構之間加入張力檢測設備，藉由對被傳送的材料進行張力檢測，並依設定的張力值作為基準，修正傳動導輪的速度，以使材料能在穩定的張力下提升50%以上的加工速度、精度及穩定度，進而提升設備產能與稼動率，降低材料損耗及生產成本，提高良率及毛利率與國際競爭力。[[abstract]]Abstract The technique of material tension control has been adopted widely due to the booming development of electric technology and packing industry. The strong demand of high speed and accuracy of multiple repeating manufacturing for reel material demonstrates the importance of this technique. By increasing tension controller, this paper aims to reduce the inaccuracy of power roller circumference that causes the inaccuracy of accumulating speed among different work stations during the process of material manufacturing of reel equipment. Especially, the characteristics of material (such as extensibility, flexibility…) or the manufacturing accuracy of equipments create the inaccuracy speed of material manufacturing and affect the quality of manufacture due to material damage or extensibility in the process. To solve this problem, the tension measuring equipment is installed between two power rollers to test the extension of delivered material and fix the power roller’s speed according to the value of tension. Under stable extension, the speed, accuracy and stability of material manufacturing are improved more than 50%. The productivity and up time are therefore increased to reduce the cost and material damage, and promote the yield, Gross Profit Margin and the international competition ability
