    • PROBLEM TO BE SOLVED: To provide a traveling yarn line inspection method that inspects the condition of each of a plurality of yarn lines traveling in parallel on the same surface online at the same time, and obtains the defect information of each yarn line to thereby improve an yield by finding a process abnormality such as the fluctuation of a process condition early or performing the quality control of the yarn lines and yarn line packages.
      SOLUTION: The traveling yarn line inspection method inspects yarn lines traveling in parallel on the same surface. The traveling yarn line inspection method is provided with a first illumination means 2a and a line sensor for imaging the plurality of yarn lines on the side of the first surface of the traveling surface of the yarn lines and a second illumination means 2b on the side of the second surface, and includes a data processing means which processes data obtained by the line sensor and a recording means 8 which records data processed by the data processing means with time.

    • 要解决的问题:提供一种行进纱线检查方法,其同时在同一面上并行行进的多根纱线的条件进行检查,得到各纱线的缺陷信息 从而通过早期发现处理条件的波动或进行纱线和纱线包装的质量控制等过程异常来提高产量。

      解决方案:行进纱线检查方法检查在同一表面上平行行进的纱线。 行进纱线检查方法设置有第一照明装置2a和线传感器,用于对多条纱线在纱线的行进面的第一表面侧进行成像,第二照明装置2b 并且包括处理由线传感器获得的数据的数据处理装置和记录数据由数据处理装置处理的数据的记录装置8。 版权所有(C)2009,JPO&INPIT
