摘要

目前市面上販售飲料，普遍採用的幾種包裝形式為：玻璃瓶、馬口鐵易拉罐、鋁質易拉罐、無菌鋁質複合包、PET瓶及塑膠罐頭瓶裝...等；近年來，由於PET瓶材料與製造技術的突破，PET瓶成為飲料包裝的主流。吹瓶機之吹瓶流程概分為：加熱、入胚、合模、吹氣、出胚五種流程，控制這五種流程之機構稱為開關(合)模機構。
目本研究之目的在於重新設計的開關(合)模機構，並希望它具有更好的運動和動力特性。首先，搜尋與研究相關機構(專利及文獻資料)作為本研究之參考；並分析銓寶公司所提供直線式吹瓶機之運動特性；接著，利用型態分析法進行開關模機構設計，合成出60組機構，挑選A1B1C1、A2B1C1、A5B4C2三組進行運動模擬與動力分析，其中A2B1C1側模運動之加速度可降低38.94%、A5B4C2側模運動之加速度可降低29.73%；A2B1C1底模運動之加速度可降低63.37%、A5B4C2底模運動之加速度可降低38.85%。A2B1C1 和A5B4C2 兩種組合均較現有機構具備更好的運動特性。

The package of drinks can be: glass bottles, tin cans, aluminum cans, plastic bottles, and PET bottles. As the material and manufacture technology breakthroughs, PET bottle becomes the mainstream of drink package. The processes of blow-molding machine are: heat, in-feed, mold close, blow, and mold open. Open-Close Mold Mechanism can mainly control these five processes.
The purpose of this research is to redesign the Open-Close Mold Mechanism and hope it has better kinematic and dynamic performances. First, collect and analyze the related mechanisms (patent and literature) as reference of this study. Also, analyze the kinematic and dynamic performances of Open-Close Mold Mechanism provided by Chumpower Company. Then, according to the method of “Morphological Chart Analysis”, 60 Open-Close Mold Mechanisms are synthesized. Three combinations (A1B1C1, A2B1C1, and A5B4C2) are chosen and their kinematic and dynamic performances are analyzed. The maximum lateral acceleration of A2B1C1 (A5B4C2) can be reduced 38.94% (29.73%). The maximum bottom acceleration of A2B1C1 (A5B4C2) can be reduced 63.37% (38.85%). The two combinations (A2B1C1 and A5B4C2) are better than the existing design.
