Embodiment
The utility model is described further below in conjunction with specific embodiment, but the protection model required by the utility model
Enclose and be not limited to scope described by specific embodiment.
The device of 1 a kind of yarn detection with reference to the accompanying drawings, including luminous member control apparatus 1, illuminator 2, constant tension dress
4, imaging area 5, thread delivery device 6, condenser lens 7, imaging sensor 8, encoder 9, electronic controller 11 are put, is for making
One fixed width yarn 3 passes through imaging area 5, and yarn is driven by thread delivery device 6.The effect that yarn 3 passes through constant tension device 4
Under, it is maintained at a constant, repeatable tension state and enters imaging area 5 and complete imaging.
Illuminator 2 is provided in the enough light in imaging area 5 so that and image arrives imaging sensor 8 by condenser lens 7, with
Realize that clearly imaging is expected.The method that luminous member control apparatus 1 is controlled with output level controls the light of illuminator 2.Illuminator 2
It can be adjustable incandescent lamp.This provides the illuminator of a variable intensity and stabilization.In a preferred embodiment, image sensing
Device 8 is a linear imaging sensor, and it has the center of 18 microns of 5096 pel spacing.The camera lens of imaging sensor 8 can
With the octuple of enlarged drawing.
Imaging sensor 8 can carry out size detection and color detection, and two kinds of parameter detectings can be carried out in detection,
And then it is fault in material or process defect to identify.
Encoder 9 is the yarn delivered length for measuring thread delivery device 6.The output of encoder 9 can change into
The length of yarn, so as to obtain the linear velocity of yarn by electronic controller 11.Keyboard 10 is to be used to operator input Electronic Control
The operational order of device 11.The output of electronic controller 11 can be applied to display 12 and/or printer 13, create as needed
One visible output.Man-machine interface is not limited solely to display 12 and printer 13, in addition to keyboard, guidance panel etc..
When light is by each pixels sense imaging sensor, it will thus provide output of the voltage in imaging sensor 8.Electricity
Sub-controller 11 is included in the controller in its memory, can establish the threshold value of an adjustable imaging sensor output
Level, report Yarn detection device（Do not block）The incident light that pixel only has the maximum possible of selected quantity is connect by imaging device
The element received（Pixel）.In the embodiments described, the output for each element of imaging sensor 8 is one 16
Word.
Voltage corresponding to location of pixels is that imaging sensor is defined as farthest interval foundation in yarn unit length
Output voltage.
Because pixel output voltage has with light amount of incident directly related, high threshold level increase then corresponds to relatively small number of hair
The sensitiveness of hair, light receive the relatively small number of information for blocking each unit；Because pixel output voltage and light amount of incident have directly
Connect correlation, the relatively low threshold level yarn core intensive by gross weight is effectively filtered out.Therefore, threshold level can establish a spy
Fixed yarn is tested, to reach the priori of expected test result.
3 and Fig. 4 with reference to the accompanying drawings, the controller in the memory of electronic controller 11 are activated, to determine set
Width measured by threshold level is as follows.Electronic controller 11 receives the output electricity of 5096 pixels in imaging sensor successively
Flat, these values are compared successively, sequentially to determine whether that each pixel is considered as open（Equal to or higher than threshold
Value）Or block（Value is less than threshold value）.The signal provided by sensor can be evaluated.Reference picture 2, to illustrate yarn optics spy
Property, i.e. the determination of yarn faults.Two defects A and B are included along the sample of the length of yarn.First defect A color
Similar to sample color, second defect B color is different from sample color.First defect A is produced can be by imaging sensor
8 detect first signal I of out of size, which is beyond that a defect first threshold X.It is similar, second defect B
Produce second signal II.If the first defect A produces first out of size III detected from imaging sensor 8, its is low
In the threshold value being set, but because defect A's is similar in color in the property of sample, this defect is classified as defect type 1,
It may be called as " process defect ".Second defect B produces second out of size IV detected from imaging sensor 8
Second Threshold Y is exceeded.Therefore, defect B is classified as defect type 2, and it may be called as " raw material defect ".Size detection
When, it is electric corresponding to its location of pixels when the first location of pixels signal that electronic controller receives to imaging sensor is handled
After pressing from low to high to carry out transition, if during still above first threshold X, then it is assumed that size is defective；It is basic after completion size detection
It is synchronous to carry out color detection, when electronic controller is to the second location of pixels signal for substantially synchronously being received with the first location of pixels
Handled, height is changed after voltage corresponding to the location of pixels is first low, if still above Second Threshold Y, then it is assumed that color has
Defect, the imaging sensor is by determining the state of current pixel（Open or close）With the difference of previous pixel, to judge to be
No is defect.If it is, occurring from unimpeded transition blocking, or block, it is unimpeded.By if it is determined that previous picture
Plain voltage is greater than or is determined less than the threshold value, the type of transition.The each of controller control represents location of pixels, and mistake
The direction transition crossed.Then, controller inspection, and the transition pixel position of from low to high is determined, last low to high conversion
Location of pixels, and then realize the detection of two kinds of information.
Two or more different threshold values can be employed with many different modes, if the pipe nipple of yarn is measured,
And the relatively small number of the yarn image in shooting so that 5096 pixels of each image can be stored in electronics control
In device memory processed, different threshold values may apply to the data of this storage, so as to allow yarn one-shot measurement.
System of the present utility model, electronic controller program and method ensure that the measure of the filoplume true horizon of yarn.
This information can be used for as needed in the manufacture and processing operation of yarn.For example, the measurement of filoplume, or integral diameter and fibre core it is straight
The ratio between footpath, it can be referred to as " the filoplume factor ", may be used as a part for total grade of the yarn of manufacture.Because measurement is certainly
It is dynamic to carry out, and the filoplume factor is calculated by electronic controller, it may be used as being input to clearing technology to remove each several part of yarn
The oeverall quality of yarn package is improved with the not receivable filoplume factor.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model not limited to this,
In person of ordinary skill in the field's possessed knowledge, may be used also on the premise of the utility model aims are not departed from
To make a variety of changes, person of ordinary skill in the field is made without performing creative labour from above-mentioned design
A variety of conversion, all fall within the scope of protection of the utility model.
