Yarn coiler, automatic winder and splicing portion detection method

Abstract

The invention provides a yarn coiler, an automatic winder and a splicing portion detection method; the winding unit (10) comprises the following elements: a yarn tube support (11) supporting a yarn feeding tube (B), a coiling portion coiling on the yarn (Y) of the yarn feeding tube supported by the yarn tube support, a splicing device (31) arranged between the yarn tube support and the coiling portion so as to splice the yarn on the yarn tube support side and the yarn on the coiling portion, a size obtaining portion (110) obtaining the size of the yarn splicing portion using a splicing unit to splice the yarn, a force obtaining portion (120) obtaining the force of the yarn splicing portion, and a detection control portion having a normal mode and a detection mode, wherein the detection control portion can switch the yarn coiling on the yarn feeding tube so as to form a coil work in the normal mode, and the detection control portion can use the size obtaining portion and the force obtaining portion to obtain the yarn splicing portion size and force, thus outputting a detection value in the detection mode.

Description

technical field [0001] The invention relates to a yarn winding machine, an automatic yarn winder and an inspection method for a yarn splicing part. Background technique [0002] There is known a yarn winding machine for winding a yarn of a yarn supplying bobbin into a package. In the yarn winding machine, after removing the yarn defect or replacing the yarn supplying bobbin, the yarn splicing device is used to connect the lower yarn on the yarn supplying bobbin side and the upper yarn on the package side. In the above-mentioned yarn winding machine, in order to produce a package with a specified specification, when changing the size of the yarn type and yarn count, for example, the yarn splicing nozzle of the yarn splicing device is replaced, or the setting of the yarn splicing device is adjusted. Set items (for example, seam length and twisting time, etc.). [0003] In the above-mentioned yarn winding machine, when the scale is changed, in order to confirm whether the rep...

Problems solved by technology

[0005] However, there is a concern that the inspection accuracy cannot be maintained constantly in the inspection of the dimensions of the spliced ​​yarn portion based on visual observation.

In addition, the inspection of the strength of the yarn splicing part by the measuring device requires careful attention to the correspondence between the yarn winding machine and the sampled yarn, which is very labor-intensive and time-consuming.
