Apparatus and method for engraving marks on spun bobbins

Abstract

The invention discloses a marking marking device for spun yarn bobbins, which comprises an empty bobbin box, an empty bobbin conveyor belt and an engraving workbench. Several empty bobbin bobbins are stacked in the empty bobbin box, and the empty bobbin bobbins are transported through the empty bobbins. The belt is transported to the engraving workbench, which includes a worktable, and a yarn bobbin empty tube drop slot is arranged on the side of the workbench close to the conveyor belt body, and the yarn bobbin empty tubes are transported to the worktable by the conveyor belt body Roll and fall into the trough of the bobbin empty bobbin; above the working table, there is an inkjet printer or code engraving machine for marking the bobbin empty bobbin, and on one side of the working table is a The driving device for the rotation of the bobbin empty bobbin. The present invention can directly engrave markings such as codes on the empty tubes of the bobbins, which facilitates the positioning and tracking of the bobbins, and the quick search when the detected yarns on the bobbins do not meet the requirements, and has the advantages of simple and convenient mark engraving and low cost , has no effect on bobbin structure and spinning quality.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a spun bobbin mark-engraving device for traceability of spun yarn bobbins, and a method for engraving the spun bobbin mark by using the mark-engraving device. 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 spindle that produced the spun yarn on this bobbin. The method commonly used in the industry at present is to search ingots one by one, which is time-consuming and laborious, and the effect is not good...

AI Technical Summary

Problems solved by technology

To integrate the RIFD electronic tag on the bobbin, at present, there are two methods of embedding the RIFD electronic tag inside the bobbin or sticking the RIFD electronic tag on the bobbin surface. The method of embedding the RIFD electronic tag inside the bobbin requires the structure Larger changes are required, and the implementation cost is high. Although the RIFD electronic label is directly attached to the bobbin surface, it has little effect on the bobbin structure, but it is easy to fall off.

In addition, when the RIFD electronic tag is running at high speed, it will also produce problems such as induced electromotive force

To sum up, it can be seen that integrating RIFD electronic tags on the bobbin has a series of problems such as high cost, the need to change the structure of the bobbin, and the impact on spinning quality.
