基于红外传感器的环锭纺断纱在线检测装置

为了解决环锭纺纱在纺纱过程中细纱断头难以及时发现的问题,提高纺织企业的生产效能,设计了基于红外传感器的环锭纺断纱在线检测装置,装置包括红外传感器、双运算放大器和单片机控制模块。在环锭细纱机上试纺18.2 tex棉纱,利用环锭纺断纱检测装置对纺纱过程中的细纱气圈信号进行在线检测。实验结果表明,装置将细纱气圈信号转换成电信号,再经过单片机控制模块处理判断,准确实现了细纱断纱在线检测。为了验证装置对棉纱的品种适应性,对5.8 tex、9.7 tex、18.2 tex三种纱支的棉纱进行检测。结果表明,装置能够实现对市场上大部分棉纱的断纱在线检测。

On-line detection device for ring spun-yarn breakage based on infrared sensor

In order to solve the problem that yarn breakage can not be found in time during the spinning process and improve the production efficiency of the textile enterprises,on-line detection device for ring spinning yarn breakage based on infrared sensors was designed.The devices include an infrared sensor,a dual operational amplifier and a microcontroller control module.18.2 tex cotton yarn was spun on ring spinning frame,and yarn breakage was detected with the proposed device.The experimental results show that the device can convert the spinning balloon signal into electrical signal,and then through the processing and judgement of the microcontroller control module,on-line detection of the yarn breakage can be accurately realized.In order to verify the adaptability of the cotton yarn,the cotton yarns of 5.8tex,9.7tex and 18.2tex yarns were tested.The results show that the device can achieve on-line detection of most yarns on the market.
