Problems solved by technology

[0003] At present, the LED light source used for the detection of hairy defects is used to supplement the light. The disadvantages are as follows: 1. In this way, the hairs in the picture taken from one angle will appear again at other angles, and it is impossible to judge whether it has been repeatedly detected. out
2. The LED light source is relatively divergent. During the irradiation process, the height of the hairs that need to be detected cannot be judged, and the hairs that do not need to be counted as defects will also be included in the statistics, which will easily affect the final calculation results.

Embodiment 1

[0058] The textile silk roller 4 is placed on the rotating tray 1, and the rotation of the rotary tray 1 can drive the textile silk roller 4 to rotate by 360°. The upper end surface of the laser transmitter 3 and the textile silk roll 4 is kept horizontal, and the laser transmitter 3 and the camera 2 are installed on the same horizontal plane. In this way, the camera 2 can photograph the moment when the laser is irradiated to the wool of the silk roll.

Embodiment 2

[0060] 1. Place the textile silk roll 4 on the rotating tray 1.

[0061] Such as figure 1 As shown, the axis of the textile silk roll 4 and the axis of the rotary tray 1 are kept consistent in the vertical direction.

[0062] 2. Adjust the angles of the camera 2 and the laser transmitter 3 .

[0063] Such as figure 2 As shown, the camera angle of the camera 2 needs to be adjusted to form an angle of 90° with the axis of the laser emitter 3 , that is, the angle of the camera of the camera 2 needs to form a 90° angle with the laser beam of the laser emitter 3 .

[0064] 3. Calculate the rotation angle α of the rotating tray 1 in the interval time when the camera 2 takes pictures of the textile yarn roll 4 .

[0065] ①. Calculation of the angle α of the rotation of the rotating tray 1 during the interval when the camera 2 takes pictures of the spinning roller 4:

[0066] α=2arcsin(D / 2R)

[0067] Wherein R is the radius of the inspected textile silk roll 4, and D is the thic...

Abstract

The invention discloses a textile silk roller broken filament defect detection method, belongs to the technical field of broken filament detection, and aims to realize broken filament detection in a local area irradiated by laser by utilizing the characteristic of good directivity of the laser. The camera angle of the camera needs to be adjusted to form an angle of 90 degrees with the axis of thelaser emitter, that is, the angle of the camera of the camera needs to form a 90-degree angle with the laser ray of the laser emitter, and the divergence angle of the laser beam is very small, so thatin the rotating process of the wire roller, an area which cannot be repeatedly irradiated within 360 degrees is formed, and broken filaments in the area scanned by the laser can be accurately countedand counted. The method is scientific, reasonable and safe and convenient to use, the distance between the laser beam and the end face of the wire roller is adjusted, and short broken filaments without defects can be avoided. Therefore, the problem which cannot be solved only through an image processing algorithm can be solved from the source of image acquisition.

Description

technical field [0001] The invention relates to the technical field of fluff detection, in particular to a method for detecting fluff defects of textile silk rolls. Background technique [0002] For the current production process of various silk threads, it is inevitable to produce wooly yarns containing defects, and the detection of wooly yarns on textile silk rolls is an inevitable process. [0003] At present, the LED light source used for the detection of hairy defects is used to supplement the light. The disadvantages are as follows: 1. In this way, the hairs in the picture taken from one angle will appear again at other angles, and it is impossible to judge whether it has been repeatedly detected. out. 2. The LED light source is relatively divergent. During the irradiation process, the height of the hairs that need to be detected cannot be judged, and the hairs that do not need to be counted as defects will also be included in the statistics, which will easily affect ...
