Description

Spandex covered yarn defect monitoring device

Technical Field

The application relates to the field of textile preparation, in particular to a monitoring device.

Background

The spandex covered yarn is elastic yarn formed by covering the spandex yarn in an extended state in a spiral manner by using the spandex yarn as a core and using filament yarn or short fiber yarn;

the spandex covered yarn can be divided into a single covering and a double covering according to the number of covered layers, and the difference is the difference of the number of layers and the wrapping degree of the covered yarn.

The single-covered yarn is formed by covering an outer covered yarn (yarn) on the outer layer of the core yarn spandex, the number of turns is less, the exposed core of the fabric is obvious, and the single-covered yarn is not suitable for being used as a dark color product. Is mainly used for elastic fabrics such as socks, weft-knitted underwear and the like.

Double covered yarns are yarns or filaments covered by two layers of spandex core yarn, wherein the two layers of covered yarns are generally opposite in direction. The covered degree of the spandex of the core yarn is good, the uncovering phenomenon is light, and because the outer covered yarn symmetrically covers the core yarn by the reverse spiral angles, the elastic force of the covered yarn is good, the subsequent processing can be carried out generally without shaping treatment, but the processing cost of the double-covered yarn is higher. Is mainly used for elastic fabrics such as leg guards, elastic bands, sock mouths, pantyhose and the like.

One of the very important quality indexes of spandex-covered yarns is the presence or absence of exposed or broken spandex yarns; if the finished spandex-covered yarn has excessive defects, the strength of the spandex-covered yarn is reduced, and the user experience is influenced; the defects of the spandex-covered yarn are difficult to detect manually because the spandex-covered yarn has a thin wire diameter and a long length to be detected; the invention provides a spandex filament exposure monitoring device which can automatically detect whether spandex filament exposure or filament breakage exists on spandex covered yarns.

In one embodiment, the spandex covered yarn defect monitoring device comprises:

an unwinding apparatus 1 mounted with a first wire roll 113; the unreeling device 1 further comprises a first driving piece; the first driving member drives the first wire roller 113 to rotate in a first plane;

a winding device 2 mounted with a second wire roller 213; the winding device 2 further comprises a second driving element and a third driving element, wherein the second driving element drives the second wire roller 213 to rotate; the third driving member drives the second wire roller 113 to rotate in a second plane; under the driving of the first driving member and the third driving member, the first wire roller 113 and the second wire roller 213 rotate coaxially and synchronously; and

an inspection apparatus 3 including an AOI vision inspection device; the AOI vision detection device comprises a CCD camera device; the CCD camera device is arranged between the unreeling device 1 and the reeling device 2 and used for collecting image data of the fiber yarns passing through the unreeling device 1 and the reeling device 2;

the CCD camera device is characterized in that limiting parts are arranged at two side positions of the CCD camera device along a first direction x, limiting holes (1111 and 2111) are formed in the limiting parts, the limiting holes (1111 and 2111) are coaxial, the axial direction of the limiting holes is along the first direction x, and the limiting holes (1111 and 2111) supply the fiber filaments to penetrate so as to limit the extending direction of the fiber filaments.

It is to be understood that the above-mentioned fiber yarn may be the spandex covered yarn 5.

It can be understood that the semi-finished spandex coated yarn 5 is wound on a winding core 4, and the winding core 4 is of a tubular structure and comprises a main body and limiting parts positioned at two ends of the main body; the main body is of a cylindrical tubular structure; the limiting parts at two ends are annular plates sleeved on the main body; the wire winding core 4 can be sleeved on the first wire roller 113 of the unreeling device 1; further, the winding core 4 is in clearance fit with the first wire roller 113, and can rotate freely relative to the first wire roller 113.

It can be understood that the winding core 4 is also sleeved on the second wire roller 213 of the winding device 2, and the winding core 4 cannot rotate freely relative to the second wire roller 213, that is, when the second driving member drives the second wire roller 213 to rotate, the winding core 4 also rotates synchronously; this can be achieved by various structures, for example, the cross section of the second wire roller 213 is a polygonal structure, and the channel of the wire winding core 4 located on the second wire roller 213 is also relatively arranged to be a polygonal structure, so as to prevent the wire winding core 4 from rotating relatively to the second wire roller 213.
