摘要: 介绍一种能在粘胶长丝的络丝工艺过程中实时检测毛丝的方法。该方法用光线照射粘胶长丝上的毛丝,将毛丝在光电传感器的敏感面上形成放大的影像,使光电管的受光量减弱,由此可以检测出毛丝信号,通过电路处理后还可以实现对毛丝的计数。基于此方法设计了毛丝检测装置,该装置以毛丝检测电路为基础,使用89C51单片机作为系统的主控制器,通过信号处理电路、计数测量电路、功率调节电路、键盘显示电路、执行机构驱动电路,完成毛丝检测和计数的功能。经过实际运行表明,该系统稳定可靠,成本较低且体积小。

Abstract: The paper introduces a method for real-time detecting broken filaments in the process of winding viscose filaments.By illuminating viscose filaments,the broken-filaments will become an enlarged image on the sensitive surface of the photo electricity sensor,and the image will weaken the luminous flux of photoelectric cell,by monitoring the signal,the system can detect and count broken filaments.Based on this concept,designed a kind of device for detecting broken filaments for viscose filaments based on the circuit detecting principle.It used single chip process 89C51 as the host and accomplish broken filaments detection and counting by the circuits of signal processing,counting,power governing,displaying,and implementing and driving.It has been proven by practical running that the device is characterized by reliable and stable operation,compactness and low cost.
