                          摘要:為了保證細紗機集落系統可靠、高效插拔紗管,介紹集落裝置用抓管器功能、結構型式及工作原理,分析活塞式抓管器和氣囊式抓管器的失效形式,詳述二者使用密封滑動墊的工作原理、破損機理及影響其可靠性的因素和提升措施;計算活塞式抓管器的握持力,從能效轉換角度說明增加抓管器握持力的方法,并提出改進方向。指出:密封滑動墊或氣囊疲勞破損產生漏氣是抓管器失效的主要原因,集落裝置的凸盤型式和紡紗工藝對滑動密封墊可靠性有影響;密封滑動墊漏氣影響集落裝置動作的正確性,應在設計、生產加工及使用等全過程采取措施提高其性能;為活塞式抓管器增設類似波紋管的軸向可伸縮結構,使密封滑動墊膜片獲得較大的軸向伸縮量,延長使用壽命;使用軟質壓頭和抓管喇叭調節塊,改進紗管頭部結構和壓頭結構等措施有利于增大抓管器握持力和提高能效轉化率。

                          Abstract:In order to ensure the reliability and high efficiency of inserting and pulling yarn tubes in the collective doffing system of spinning frame,the function,structure type and working principle of the bobbin grabber used in the collective doffing device are introduced,and the failure forms of piston bobbin grabber and air bag bobbin grabber are analyzed.The working principle and damage mechanism of seal sliding pad used in piston bobbin grabber and air bag bobbin grabber,as well as the factors affecting its reliability and improving measures are described in detail.The grip force of the piston bobbin grabber is calculated,the method of increasing the grip force of the bobbin grabber is explained from the factor of energy efficiency conversion,and the direction of improvement is proposed.It is pointed out that air leakage caused by fatigue damage of seal sliding pad or air bag is the main reason for failure of bobbin grabber.The raised disk type and spinning process of the collective doffing device have influence on the reliability of the seal sliding pad.The air leakage of the seal sliding pad affects the correctness of the movement of the collective doffing device,so measures should be taken to improve the performance of seal sliding pad in the whole process of design,production and use.An axial scalable structure similar to bellows is added to the piston bobbin grabber,so that the diaphragm of the seal sliding pad can obtain a larger axial expansion and extend the service life.Using the soft indenter and the adjusting block of the grab horn,improving the structure of the head and the inden-ter to yarn tube are beneficial to increase the grip force of the bobbin grabber and improve the conversion rate of energy efficiency.
