具變導程螺桿之直線式吹瓶機是由加熱系統、直線式吹瓶模座、變導程螺桿傳送系統、及出入胚系統組成。變導程螺桿傳送系統由滑塊、固定螺桿、旋轉螺桿、及夾爪裝置組成，目的是將瓶胚從加熱區傳送至吹瓶模座區，其設計影響整個吹瓶機之效率。本研究提出一套系統化方法，設計變導程螺桿傳送系統之運動，以提昇吹瓶機之性能。首先，根據傳送系統作動時之設計需求與限制，分析吹瓶機入瓶輸送裝置系統之運動，以基本的凸輪運動曲線(修正梯形曲線、修正正弦曲線、修正等速度曲線)生成運動曲線函數，並以牛頓運動原理與壓力角之定義進行凸輪系統的壓力角分析與靜動力分析；接著利用最佳化原理設計Bezier與Fourier series曲線，改進運動與靜動力特性。本研究利用最佳化法所設計的運動曲線，改善了吹瓶機之傳送系統的運動與靜動力特性，且降低變導程螺桿之壓力角與系統運作時所需的輸入力。

The linear type blow-molding machine with a variable pitch lead screw consists of a heating system, a linear blow-station, a variable pitch lead screw transmission system, and an infeed-and-outlet system. The va-riable pitch lead screw (VPLS) transmission system consists of a slider, a fixed screw, a rotary screw, and a catch device. It transfers the bottle from the heating system to the blow-station. The design of the motion of VPLS transmission system affects the efficiency of blow-molding machine. This works presents a systematic analytical method to design the motion of VPLS transmission system to improve the performance of blow-molding machine. Firstly, the motion of the VPLS transmission system is analyzed. Based on the design requirements and constraints of the motion of trans-mission system, the curve of VPLS is synthesized by applying the cam motion curves (MT, MS, and MCV). According to Newton’s law and the definition of pressure angle, the pressure angle of the cam mechanisms and the kineotastatic analysis are evaluated. The kinematic and kinetos-tatic characteristics are improved based on the optimal theorem by using the Bezier and Fourier series curves as the design curves. As a result, the motion curve by using the optimum method approach improves the ki-nematic and kinetostatic characteristics of the transmission system of the blow-molding machine and decreases the pressure angle of the VPLS and the input force of the transmission device.
