Automatic tracing and positioning system for falling-behind spindles corresponding to spun yarn and bobbin linkage defected yarn tubes

Abstract

The invention discloses an automatic tracing and positioning system for falling-behind spindles corresponding to spun yarn and bobbin linkage defected yarn tubes. An engraving device for conducting encoding and marking on spun yarn tubes, a first information collecting device used for collecting the encoding information on the spun yarn tubes and the spindle position information corresponding to the spun yarn tubes, and a second information collecting device used for collecting encoding information of yarn tubes in an automatic winder yarn warehouse are included. According to the automatic tracing and positioning system, on the basis of the principle of scanning recognition, codes are marked on the tops of various yarn tubes, and a scanner sequentially scans the codes of various yarn tubeson a spinning machine and meanwhile scans the position information of spindles corresponding to all the yarn tubes; the means that a code scanner is arranged at the last preparing station before winding in the automatic winder yarn warehouse and scans the code of the yarn tube at the last preparing station before winding in the yarn warehouse, and meanwhile the work time information of the yarn tube is recorded are adopted, so that falling-behind spindle automatic tracing is achieved, and compared with a spindle-by-spindle searching manner, efficiency is obviously improved, and tracing reliability is high.

Description

technical field

[0001] The invention belongs to the technical field of spinning, and in particular relates to a rapid and automatic traceability and positioning system for backward spindles of defective yarn bobbins produced by fine-coil linkage. Background technique

[0002] In the spinning workflow, the last two processes are spinning and winding. The spun yarn is wound on the spun yarn bobbin, and after the quality of the yarn is tested in the winding process, the qualified yarn is packaged on the cone bobbin and becomes the final product before leaving the factory. If the winding process detects that the quality of the yarn on a bobbin does not meet the requirements, the automatic winding machine will automatically reject it, but it is very difficult to find the outdated spindle that produced the spun yarn on this bobbin. At present, the method commonly used in the industry is to search ingots one by one, which is time-consuming, laborious and inefficient. Contents of...
