摘要


毛巾織機以運動方式分類可分成五大運動機構,分別為開口、引緯、打緯、捲取、送經運動機構,而其運動方式為開口機構將織口打開始引緯機構可順利將緯紗引入織口,打緯機構則是將引入織口的緯紗進行緊密的排列,捲取機構則是將編織完成的胚布引離織口,送經機構則是將經紗送出。而送經機構主要的功能為確保織造過程中經紗可穩定的由下經紗退繞送出,使織造過程連續且不間斷。而送經機構可分為經紗送出裝置及張力調節裝置,經紗送出裝置是將棉紗穩定的退繞送出,張力調節裝置是在調節棉紗從上機到織造時的張力變化,以因應不同織物在不同製程條件下的控制。本研究論文將針對張力調節裝置作進一步分析探討,文中將對片梭織機之單後樑及雙後樑張力調節裝置作運動模擬及運動位置分析,並利用簡單的數學方程式比較出兩種後樑系統之差異性。

There are five main modulus including opening, weft guiding, tying weft, take-up, and weft deliver mechanism in towel textile machines. The function of each modulus provides an exact motion for towel manufacture. The opening mechanism make the wrap open to let weft can pass inside the hole. The tying weft mechanism makes sure the wrap and weft can be arranged regularly. The component of the towel includes the loop area and the ribbon area which provides different function. The weft form a small loop in the loop area of the towel and the weft deliver by the weft deliver mechanism should longer than the ribbon area. Too much length or short wefts for these tow area make the towel quality bad. In this study, two different weft deliver mechanisms, single shaft and twin shafts are analyzed theoretically first, then an experimental test is implemented in towel manufacture factory to compare their difference in efficiency. The result shows that twin shafts type provide accuracy motion than the single shaft type machine. However the complexity of this machine makes difficulty in tension of the weft control.
