    • A warp insertion monitoring method and apparatus for positively protecting woven cloth from defects due to warp insertion error or failure. A warp detector is disposed on a loom so as to have a warp presence/absence detection region located at a front or rear side and in the vicinity of a reed which serves for beating a weft inserted through a shedding formed by the upward/downward motion of healed frames against a cloth fell. The presence or absence of abnormalities in respect to the positions at which warps are inserted through the reed is identified on the basis of detection information available from the output of the warp detector. Detection timing for the warp detection information is so established as to fall within a period during which the loom is stopped, so that the presence or absence of errors in respect to the warp insertion can be detected before the loom is restarted.
    • 一种经纱插入监测方法和装置,用于由于经纱插入错误或故障而积极地保护织布免受缺陷。 弯曲检测器设置在织机上,以便具有位于前后侧和在筘附近的经纱存在/不存在检测区域,该筘片用于通过由向上/向下运动形成的脱落插入的纬纱打纬 治疗框架对着布下落。 基于从翘曲检测器的输出可获得的检测信息,识别出通过舌簧插入经纱的位置的异常存在或不存在。 弯曲检测信息的检测定时被建立为落在织机停止的时间段内,从而可以在织机重启之前检测是否存在相对于经纱插入的错误。

    • A coating quality measuring device has a pattern plate including one reference pattern portion having a larger pattern width and a plurality of strip pattern portions having different pattern widths which are smaller than that of the reference pattern portion and are decreased in order. The pattern plate is disposed opposite the coated surface. The pattern plate is reflected on the coated surface and a reflected image is formed on an image sensor. The image sensor successively outputs signals each corresponding to the lightness of each pattern portion on a line extending in a width direction of each pattern portion of the reflected image. A computing device calculates a difference between the peak value of the signal level of the output signal corresponding to each strip pattern portion in the reflected image and the signal level of the output signal corresponding to the ground portion, divides the calculated difference by the signal level of the output signal corresponding to the reference pattern portion and detects the pattern width of the strip pattern portion wherein the division value becomes not larger than a predetermined value, thereby to obtain the coating quality of the coated surface.
    • 涂层质量测量装置具有包括具有较大图案宽度的一个参考图案部分和具有小于参考图案部分的图案宽度不同的多个条形图案部分的图案板,并且依次减小。 图案板与涂覆表面相对设置。 图案板在涂覆表面上反射,并且在图像传感器上形成反射图像。 图像传感器在反射图像的每个图案部分的宽度方向上连续地输出与每个图案部分的亮度相对应的信号。 计算装置计算与反射图像中的每个带状图案部分相对应的输出信号的信号电平的峰值与对应于接地部分的输出信号的信号电平之间的差值,将计算出的差除以信号电平 并且检测分割值不大于预定值的带状图案部分的图案宽度,从而获得涂覆表面的涂布质量。
