The method comprises the following specific steps:

(1) the code is marked on the top of each bobbin. The code can adopt common two-dimensional codes, bar codes and the like, and other standard codes can be adopted. In addition, the coding system may also be constructed by self-coding, which is not limited herein.

In this embodiment, a code such as a two-dimensional code is engraved or sprayed on the top of the bobbin by means of engraving or spraying a code. The top position can be well recognized by devices such as a bar code because no yarn is wound.

In addition, in order to ensure that the code information on each bobbin can be accurately and reliably identified by devices such as a code scanner, the invention also creatively designs that a plurality of codes are marked in a certain circumferential direction at the top of each bobbin. The number of the codes is three, four, five or even more, so that when the bobbin is on the spindle, no matter which position of the bobbin the code scanner is aligned with, one code information can be acquired, and the reliability is obviously improved.

(2) And a first code scanner is used for scanning the codes of all the yarn tubes on the spinning frame in sequence, and meanwhile, the position serial numbers of the spindles corresponding to all the yarn tubes are recorded through the position check code scanner, so that the relation between the yarn tube codes and the spindle positions is established in sequence.

(4) And carrying out online quality detection on the yarn on an automatic winder, and when the quality of the yarn is detected to be qualified, winding the qualified yarn on a cone to obtain a final product which leaves the factory.

And when the quality of the yarn is detected to be unqualified, the defective yarn bobbin is removed. Meanwhile, in order to trace back the lagging spindle, the automatic bobbin winder searches the coding information of the bobbin according to the working time of the winding spindle and the working time information of the bobbin.

(5) And searching spindle position information corresponding to the coded information of the yarn tube from a spinning database, and finding out the position of the backward spindle.

Furthermore, a plurality of coding marks 441 are required to be arranged at the end of each spun yarn bobbin, and the coding marks 441 are distributed at intervals around the end of each spun yarn bobbin. The coded mark can be made on the bobbin by using an ink-jet printer or a code engraving machine. Meanwhile, the position information of the spindle and the coding information on the spun yarn bobbin produced by the spindle are collected and stored in a database in advance. Specifically, various means can be adopted, for example, the encoded information on the spun yarn bobbin produced on a certain row of spindles is sequentially scanned by devices such as a code scanner, that is, the encoded information on the spun yarn bobbin produced by a certain row of first spindles is firstly collected, then the encoded information on the spun yarn bobbin produced by a second spindle is collected, and the above steps are sequentially carried out, so that the position information of the upper spindle and the encoded information of the spun yarn bobbin produced correspondingly can be stored in the database. Therefore, after the position information of the lagging spindle is determined, the defective yarn bobbin coding information correspondingly produced by the lagging spindle can be searched and determined. The spindle can also be coded, and the coded information on the spindle and the coded information on the spun yarn bobbin produced by the spindle are simultaneously collected during collection, the link between the position of the spindle and the coded information on the spun yarn bobbin produced by the spindle is established, and the link is stored in a database.

The third code scanner 41 arranged on one side of the conveying belt is also connected with the database, and the third code scanner 41 transmits the coded information of each passing spun yarn bobbin on the scanned conveying belt to the database for comparison, so as to determine whether the passing spun yarn bobbin is a defective spun yarn bobbin produced by a lagging spindle. The database is connected with the control device, the control device is connected with the first motor of the rejecting structure, and the connection mode is a conventional means. When the spun yarn bobbin is determined to be a defective yarn bobbin produced by a backward spindle, the database transmits a defective yarn bobbin removing instruction to the control device, and the control device controls the removing structure to move to remove the defective yarn bobbin from the conveying belt, so that the quality qualification rate of the yarn on the spun yarn bobbin conveyed to the yarn storage of the bobbin winder can be ensured.
