A system and method for detecting appearance defects of chemical fiber tail

Abstract

The invention discloses a chemical fiber tail fiber appearance defect detecting system and method. The system comprises a tray for carrying a fiber ingot, and a conveying belt for conveying the tray.The fiber ingot is provided with a label. A hidden box is arranged on the conveying belt. A sorting unit is arranged on a transmission belt of the hidden box. An image collecting unit for collecting alabel image and a fiber ingot image is arranged in the hidden box. The image collecting unit sends collecting information to a processing unit to carry out tail fiber defect detection. The system recognizes and reads the label information from the label image, screens a to-be-detected image provided with a fiber ingot paper tube from the fiber ingot image, detects the edge of a paper tube area ofthe to-be-detected image, extracts the main feature describing the paper tube area, brings the to-be-detected image after being processed into a tail fiber classifier to be classified, obtains the fiber ingot tail fiber detecting information and sends the information to the sorting unit, and the sorting unit sorts qualified fiber ingot products and reject fiber ingot products according to fiber ingot tail fiber classification. The system saves the cost, the working efficiency is higher, and detecting is more accurate.

Description

Technical field [0001] The invention relates to the technical field of wire spindle defect detection, in particular to a system and method for detecting defects in the appearance of chemical fiber filament tails. Background technique [0002] There are four main factors that produce chemical fiber yarn without tail. Operation reason: When raising the head, leave the tail, but not well, it may be due to the tendency of personnel. Process factor: The process setting of the tail wire is inappropriate. Paper tube factors: the length of the tail wire groove, the depth, and the angle of the incision are inappropriate, or the length of the paper tube is not suitable. Equipment factor: Some domestic equipment is not good at keeping tails. [0003] At present, most of the production lines of chemical fiber spindle production plants adopt the manual inspection method of manual appearance observation. However, the manual inspection is labor-intensive and low in production efficiency. It ca...
