Description
Technical field
The present invention relates to a kind of spilt filament detection device, the especially a kind of viscose filament yarn spilt filament detection device that can in the reeling technological process of viscose filament yarn, monitor lousiness in real time.
Background technology
Lousiness situation to viscose filament yarn detects in real time, and the working condition that has viscose rayon yarn in China now is descending very important meaning.This is because the production equipment technology level of China now is low, a large amount of production equipments is more outmoded, if all change up-to-the-minute sophisticated equipment into, eliminates existing equipment, the quality of product can be improved immediately comprehensively, but because too huge being practically impossible of investment.The present invention fully excavates the potentiality of existing equipment, obtains the income of effectively improving the quality of products with less investment cost, has solved a very big problem for each big chemical fibre factory is anxious.
So-called lousiness is meant that strand is injured and is the phenomenon that young pilose antler phenomenon or single wire fracture, silk head protrude from the multifilament surface.
Lousiness is an important quality index of viscose filament yarn, and what of lousiness quantity in the tube length silk are one become, and directly have influence on the quality grade of this tube.From the user perspective of long filament, this index to warping, weave and dyeability all has very big influence, determined the quality of subsequent product to a great extent.In the quality index of several evaluation viscose filament yarns, most indexs all can obtain effective guarantee by strict control measure, raising workman's operant level and quality, have only the lousiness problem not solve according to manpower.Its reason is viscose filament yarn very thin (the thickest about about 400 microns), lousiness more tiny (the thinnest 19 microns), if do not pay special attention to, naked eyes are several invisible.Even if the quality grading worker to the detection of lousiness, also can only rely on range estimation, decide the grade of a silk tube by the number of " number " wire vent tube end face lousiness appearance.This is actually very insecure, because exhausted most silk is to be wound in the middle of letter, exposes few part of the whole tube silk of only accounting for of bobbin surface and end face.So long filament production firm often is subjected to customer complaint, scold that its product inherent quality and nominal level are not inconsistent, and then claim compensation.Consequently the prestige on quality of product descends, and brings serious negative effect for the brand of product, the benefit of enterprise.Technologic in addition reason often causes the appearance of a small amount of intensive lousiness to make whole bobbin reduce to off standard, causes the significantly downslide of benefit.
Treating on the problem of lousiness, the attitude of each countries and regions has very big difference.As produce the countries and regions that the equipment technology level is higher, technology is advanced, lousiness generally can not become the problem that influences quality, thereby seldom considers the assurance to quality from the detection of dynamic aspect of lousiness.Opposite in the low place of production equipment technical merit, lousiness problem troublesome, also not seeing so far can the actual device for dynamically detecting that comes into operation.In relevant research document, focus mostly in rigidity thread or other the detection than robust fibre (as glass fibre) bigger to various diameters are discussed, as calibrate, survey surface imperfection etc., main means are to utilize electric transducer or photoelectric sensor that the correlation parameter of measured object is converted to electric signal, and one of them typical application is to adopt ccd sensor to realize the detection of dynamic in line footpath.It is feasible fully, ripe seeing technically the pick-up unit that constitutes with these methods is single, independently using, and the single assembly cost is higher not to be had very yet influences.The regrettably detection of these devices and inapplicable long filament, one of reason be long filament be not rigidity and lousiness too tiny, if do not take special measure, general sensor can't detect corresponding signal at all, it two is that platform number, the number of spindles of spooler is too many, cost to single assembly is too responsive, and this class achievement in research in fact detects in real time at the lousiness of viscose filament yarn and can not get using and promoting.
The foundation of spilt filament detection is that normal viscose filament yarn is even, smooth, has the local silk head of lousiness to protrude from the multifilament surface, and silk thread has the young pilose antler phenomenon.Utilize this feature can differentiate having or not of lousiness.Available noncontact optical measurement method realizes, and this device can not done any change or restriction to existing equipment and technology.The difficult point of this device is accurately to measure very tiny lousiness, makes the installation cost of developing minimum again, and the user can be accepted and high volume applications.Wherein the key issue that will solve is a Design of Sensor, requires to have simple as far as possible optical system and structure, and this has proposed higher requirement to light source, Sensitive Apparatus and corresponding treatment circuit.
Utilize prior art, possible testing scheme has following 2 kinds, measurement scheme 1: utilize high precision linear array CCD image sensor, directly viscose filament yarn is detected, can measure the diameter and the lousiness shape of viscose filament yarn.Testing scheme 2: the variation that utilizes photoelectric sensor to detect the luminous flux that viscose filament yarn blocks detects lousiness.Wherein, method one precision height is reliably acted charitably, but with high costs; Method 2 costs are low, but because lousiness is too tiny, the reliable rows of detection is poor.
Because the lousiness problem perplexs the chemical fibre industry of China for a long time, can not throw huge fund comprehensively more under the situation of new production equipment, be badly in need of finding a kind of investment less but the tangible method of benefit solves this problem.So we have just invented viscose filament yarn spilt filament detection device, it is a device of lousiness detection of dynamic cheaply, this device only needs simple installment work just can use (as R701 type bobbin-winding machine) on the existing bobbin-winding machine, can accurately detect the lousiness above the viscose filament yarn, and do not need superseded existing equipment just can improve the quality of product, saved production cost, crucial practical significance is arranged, its society, economic benefit prospect are bright and clear.
