Problems solved by technology

In this way, if a shadow occurs on the fiber strip, the shadowed part will be misdetected as a foreign object and an unnecessary removal operation will be performed, so it is not economical and efficient.

[0035] figure 1The illustrated spinning machine 1 as a yarn winding machine includes a plurality of winder units 2 arranged in parallel, a yarn splicing cart 3 , a blower box 4 , and a prime mover box 5 .

[0036] Each spinning unit 2 is configured by stretching the sliver 15 into a fiber bundle 8 , twisting the fiber bundle 8 to obtain a spun yarn 10 , and then winding the spun yarn 10 to form a package 14 . In addition, the sliver 15, the fiber bundle 8, the spun yarn 10, etc. can be collectively referred to as "fiber strands" because the fibers are connected elongatedly.

[0037] like figure 1 and figure 2 As shown, each weaving unit 2 has, as main components in order from upstream to downstream: a drafting device 7 , a weaving device 9 , and a winding device 13 . Additionally, if figure 2 As shown, each spinning unit 2 has a unit controller 25 for controlling each configuration of the spinning unit 2 . In addition, "upstream" and "downstream" in this specification...

Abstract

A textile-material monitoring device (11) that can improve accuracy in detection of a foreign matter by reducing shadows during the detection and detect a thickness irregularity of a textile material (10) favorably is provided. A clearer of the textile-material monitoring includes a light source unit (36), a light receiving unit (37) that doubles as a transmitted-light receiving unit and a reflected-light receiving unit, and a diffuser member (38). The light receiving unit (37) receives, of light emitted from the light source unit (36) toward a running spun yarn, light transmitted through the spun yarn and light reflected from the same. The diffuser member (38) arranged between the light source unit. (36) and the spun yarn (10) diffuses the light emitted from the light source unit (36) such that a degree of light diffusion in a plane orthogonal to a running direction of the spun yarn is greater than a degree of light diffusion in a plane parallel to the running direction.

Description

technical field [0001] The present invention mainly relates to a measuring device for fiber strips. Specifically, it relates to the structure of a diffusion member for diffusing light when light is irradiated to a fiber strand in a fiber strand measuring device. Background technique [0002] An apparatus for winding fiber strands such as spun yarns may include a fiber strand measuring device for detecting foreign matter contained in the fiber strands and thickness unevenness of the fiber strands. Here, as a structure for detecting, for example, the uneven thickness of the spun yarn and the incorporation of foreign matter, the following optical measuring device is generally used: The variation of the transmitted light is used to detect unevenness of the thickness, and the change of the reflected light of the light irradiated on the spun yarn is used to detect foreign matter. As a change in the amount of light, either transmitted light or reflected light is converted into an...
