Device and method for dynamically detecting multiple targets of yarns of spinning machines

Abstract

The invention relates to the field of technologies for detecting yarns, in particular to a device and a method for dynamically detecting multiple targets of yarns of spinning machines. The device comprises a CCD (charge coupled device) camera, an image processing module, a master control system, a sensing assembly, a compact spinning device and auxiliary devices. The CCD camera is provided with an illuminating system, can acquire images of the yarns and can transmit the acquired images to the image processing module, the image processing module comprises an image gray-scale transformation unit, an image filter unit, an image binarization processing unit, a sub-pixel edge detection unit and a size calibration unit, and measured yarn information is transmitted to the master control system by the image processing module and is analyzed and judged by the master control system, so that the quality of the yarns can be detected. The device and the method for dynamically detecting the multiple targets of the yarns of the spinning machines have the advantages that the quality of the yarns of the spinning machines can be automatically detected by the aid of the device and the method, and the accuracy of detection results can be improved.

Description

technical field [0001] The invention relates to the technical field of yarn detection, in particular to a multi-target dynamic detection device and a detection method for spinning frame yarns. Background technique [0002] The spinning frame plays a key role in the spinning process, and the output and quality of the spinning frame is a comprehensive reflection of the evaluation of the pros and cons of each process in the spinning process. However, during the twisting and winding process of the yarn on the spinning frame, excessive fluctuations in the diameter of the yarn line or excessive length and quantity of hairiness often occur, which will seriously affect the quality of the yarn. Therefore, it is necessary to carry out multi-indicator on-line detection of the spinning machine yarn, but the existing yarn detection device has a complex structure, and the detection result is single and inaccurate. It cannot provide information feedback for the unqualified yarn and automat...

Problems solved by technology

However, during the twisting and winding process of the yarn on the spinning frame, there are often excessive fluctuations in the diameter of the yarn line or excessive length and quantity of hairiness, which will seriously affect the quality of the yarn.

Therefore, it is necessary to carry out multi-indicator on-line detection of the spinning machine yarn, but the existing yarn detection device has a complex structure, and the detection result is single and inaccurate. It cannot provide information feedback for the unqualified yarn and automatically adjust the yarn. The relevant parameters
