摘要

本論文主要目的在探討印表機或事務機中取紙模組(Pick-up module)及送紙模組(Feed & Delivery module)的機構設計參數。研究的重點著重在進紙角度、分紙墊及取紙輪位置幾何關係，以及進紙檔片與進紙滾輪的幾何關係。研究方法是先行解析紙張的動態撓曲行為，再依據解析出來的數值建立有限元素模型，再使用Ls-Dyna模擬其動態撓曲行為。最後建立取紙模組及送紙模組幾何模型，再使用Ls-Dyna做全面性的分析。
本研究以實際的印表機設計為藍本，探討在五種不同進紙角度(65 ，70 ，75 ，80 ，85 )的條件下，取紙滾輪對紙張的力學行為及幾何關係、分紙墊與紙張幾何關係、進紙檔片及進紙滾輪對紙張的力學行為及幾何關係，進而取得這些設計參數的關係式及了解其相互間的交互作用。透過本研究的分析及數據歸納，印表機設計人員可以在設計的相關限制及設計品質要求下，去配置相關的設計參數，得到預期的結果，並减少重覆測試及設計變更的次數及時間。

This paper is to study the design parameters of printer’s pick-up and feed-delivery modules. This paper focused on feeding angle, geometry relation between pad and pick roller and geometry relation between plate and feed roller. The approach is to calculate the dynamic deflection of paper by using finite difference method. According to numerical result, a finite element model of paper is built and simulated by Ls-Dyna. Finally, a finite element model of pick-up and feed-delivery modules are built and simulated by Ls-Dyna.
This study is based on physical printer’s design. We could study dynamic effects ( including geometry and reaction) of pick roller/paper, pad/paper and plate/feed roller
constrained by the conditions of five different feeding angle (65 、70 、75 、80 、85 ). Also we could obtain the relations of those design parameters and understand their interactions. By analyzing the data collected by this study, printer designers could be guided to verify the consequence of changing different design parameters. They could choose proper configuration to get ideal result under constraints. This will be helpful on reducing test time and possibility of design changing.
