摘要:

为解决赛络纺生产过程中粗纱断纱难以及时发现的问题,利用光电转换原理检测粗纱断纱前后纱线经过检测头所形成的方波信号,对方波信号宽度值变化特点进行横向与纵向对比。结果发现,粗纱断纱前后二者数值差异明显,由此可判断是否存在粗纱断纱现象,在 FA507B 细纱机上纺制线密度为 29.2tex 的精梳纯棉赛络纱进行验证。研究结果表明:考虑纱线粗细、表面毛羽、气圈形态变化等因素的影响,当赛络纺粗纱断纱后,单个方波的宽度较断股前增加 0.3~0.4 倍,通过此变化可间接判断赛络纺粗纱断纱情况,为后续开发赛络纺粗纱断纱检测装置提供理论依据。

Abstract:

To solve the problem that roving strand broken of siro-spinning is difficult to be discovered in time during the process of production, the square wave signal is checked in this paper by using the principle of photoelectric detection,which is caused by the yarn rununing the front of detection probe before and after roving strand broken. There is a clearly difference between each wave signal width values before and after the roving strand broken by the transverse and longitudinal comparison to change features of each wave signal width values, which can be used to judge whether there is a roving break phenomenon .In this paper, experiments spinning the fineness of 29.2 tex combed cotton siro-spinning yarn were carried out on the FA507B spinning frame to validate the conclusion. The results showed that considering the influence of such factors as the yarn thickness, surface hairiness, change of balloon shape, the width of a single square wave increased by 0.3 ~ 0.4 times after roving strand broken. The case of siro-spinning roving strand broken can be indirectly judged by this change, thus it can provide theory bases for subsequent development of siro-spinning roving break stocks detection device.
