Description
Technical field
The present invention relates to weaving sensor technical field, in particular to a kind of knitting machines people yarn defect sensors.
Background technique
In textile manufacturing, fault and it is irregular be it is recurrent, either tradition spinning or all kinds of novel spinnings, even if
Be using best spinning material, newest spinning equipment and optimal spinning process, yarn defect and it is irregular be also inevitable
's.Yarn is as the raw material in fabrication processes being both an intermediate products and subsequent technique, therefore to yarn in spinning process
Effective detection of line flaw is particularly important.Length thickness section, cotton knot, wrong branch, chain yarn defect are to influence yarn qualities
One of key factor.In rear process process, it can not only reduce bobbin-winding machine production efficiency, influence the weaving effect of loom
Rate, so that influence appearance of fabrics.With the continuous improvement of product quality and class, length thickness section, cotton knot, wrong branch, chain yarn
The influences of the yarns defect type to cloth cover quality such as defect, replacement yarn head and the tail manual splice are also to be more and more obvious.Yarn quality thus
The yarn defect sensor of detection is most important, and existing yarn defect sensor detecting method mainly has: photo-electric and condenser type can be effective
Detection yarn defect, and then improve product quality.With reference to Fig. 1, the photo-electric yarn defect sensor of Loepfe company (model:
WeftMaster FALCON-i), including shell 1 ', the photoelectric detective circuit being set in shell 1 ', the yarn for being set to 1 ' top of shell
Line current groove 11 ', the Photoelectric Detection slot for being set to the current yarn in 1 ' upper detection yarn current groove of shell, 11 ' place and it is set to shell
The current aperture frame 2 ', 3 ' of the yarn of 1 ' front and back, the current aperture frame 2 ', 3 ' of yarn are located above yarn current groove 11 '
Rear and front end makes yarn effectively can detect yarn by yarn current groove 11 ' convenient for Photoelectric Detection slot for the current limit of yarn
Whether line has the flaws such as tieing, cotton knot, thickness section, which has processor control Photoelectric Detection and provide
NPN and PNP output signal, but the photo-electric yarn defect sensor is due to yarn fibers filoplume friction generation during yarn movement
The accumulations such as many flyings be attached in the yarn current groove of yarn defect sensor will affect yarn detection judging result: cause wrong report or
It is to fail to report, influences working efficiency and fabric quality.And the cleaning of yarn defect sensor is inconvenient, manual cleaning needs to shut down, waste of manpower
Resource, while replacing yarn variety type and using detection use is started again needing that operation adjustment yarn is manually gone to start to examine again
Mark is fixed, inconvenient for use, past when a fairly large number of yarn defect sensor carries out detection yarn especially for needing to be arranged on production line
It carries out demarcating detection manually toward requiring a great deal of time, the preparation time cycle is longer, reduces working efficiency, and have
The risk of operation error.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes a kind of knitting machines people yarn defect sensor, has yarn flaws
