[[alternative]]Improvement Study Of High Speed Sewing Thread Winder

碩士電機工程學系[[abstract]]摘 要 全自動高速繞線機是一種用於生產縫紉線的機械，而縫紉線是縫紉機用於縫製衣服所使用的紗線。目前市售繞線機的結構，大都以空壓元件組合而成的自動循環動作系統，其缺點是使用者購買機械時，必需再投資設立供氣系統進而形成能源的浪費，同時空壓元件運轉時產生的噪音，對於機械操作者身體健康也有不良的影響。 本研究主要以小型電容式齒輪馬達，帶動多個凸輪組合的結構以替代由空壓元件組合的結構，達成自動循環動作，使得每錠捲取馬力從原先370W降低到180W，機台重量從1000kgs/4sp降低為500kgs/5sp，換管的時間從12秒縮短為8秒而大幅降低製造成本達50％以上，期望在市場銷售更具競爭力。 關鍵字：紡織機械、繞線機械、縫紉線機械。[[abstract]]Abstract While thread, to most people’s knowledge, is vital to the textile industry, a fully automatic high-speed sewing thread winder is also a necessary machine in producing all kinds of sewing threads or embroidery yarns. Most of the recent sewing thread winders are automatic circulation systems that are mainly composed of air compressors. When using them, operators need to set up air-supply systems which easily generate energy waste. In addition, the noise made by air compressors is also harmful to human health. This thesis proposes a multi-cam mechanism driven by gear motor of small-capacitance type to replace air-pressure devices for the improvement of the automatic circulation. The motor rating required for each bobbin decrease from 370w to 180w, with machine weight reduced from 1000kg/4sp to 500kg/5sp, and thereby shortening product exchange time from 12 to 8 seconds. This thus results in a cost reduction of 50% and an increase in the competitiveness of the market. Keywords: textile machine, fabric machine, sewing thread winder
