橫編針織機中央入紗之概念設計

本研究欲設計具中央入紗功能的橫編針織機，以輸入源傳動至各部分機構，其中離合器在此扮演重要腳色。透過離合器控制來使得紗線的進入，搭配導紗桿與導紗器的運作，達到針織的功能。本研究所設計之橫編針織機中央入紗機構與先前設計比較，控制入紗的方法較為簡單，且構造不複雜，藉此提升市場上的競爭優勢。本研究中，分別以兩種控制紗線進入的方法來進行設計構想。第一種以棘爪與棘輪為離合器的主要構造，第二種方式是透過離合器與導紗器帶動塊間的接觸來控制紗線進入。本研究首先針對橫編針織機入紗方式廣泛收集專利與文獻，並進行文獻分類與分析，再依據分析之結果歸納出優缺點。根據現行機台之模型尺寸，再以創新設計方法發展橫編針織機中央入紗機構之設計改良。本研究透過電腦輔助繪圖軟體繪製電腦模型，同時確認運動模擬及干涉檢查。

This research aims to integrate the design of Central Yard Feed Mechanisms with Flat Knitting Machine, which uses a power input mechanism, where the clutch plays an important role. The machine weaves by using the clutch to control how yarn enters the machine and by working with yarn guide bars and yarn guides. Compared with the previous designs, the central yard feeding mechanisms for flat knitting machine is devised to increase the competitive advantage in the market through the same weaving action and simpler structure of the machine. In this research, two ideas, both controlled by the clutch, are designed based on different methods of controlling how yarn goes into the machine. The first method uses pawls and ratchets as the major structure of the clutch, and the second method uses the yarn guides and the clutch to control the contact between the block and the clutch. A wide range of patents and references were collected and analyzed to find out the strengths and weaknesses of each design. The function of the current size central yard feed mechanisms for flat knitting machine is improved trough two new and innovative methods. The above two methods were verified through motion simulation and the interference check by CAD software.
