Specific embodiment
This utility model is described further below in conjunction with specific embodiment, but the protection model required by this utility model
Enclose the scope for being not limited to described by specific embodiment.
1 a kind of Yarn detection device, including luminous member control apparatus 1 with reference to the accompanying drawings, luminous body 2, constant tension device
4th, imaging area 5, thread delivery device 6, condenser lenses 7, imageing sensor 8, encoder 9, electronic controller 11, are for making one
Fixed width degree yarn 3 passes through imaging area 5, yarn to be driven by thread delivery device 6.Effect of the yarn 3 by constant tension device 4
Under, it is maintained at a tension state that is constant, repeating and imaging is completed into imaging area 5.
Luminous body 2 is provided in the enough light in imaging area 5 so that image arrives imageing sensor 8 by condenser lenses 7, with
Realize that clearly imaging is expected.Luminous member control apparatus 1 control the light of luminous body 2 in the method that output level is controlled.Luminous body 2
It can be adjustable electric filament lamp.This stable luminous body there is provided a variable intensity.In a preferred embodiment, image sensing
Device 8 is a linear imaging sensor, and which has the center of 18 microns of 5096 pel spacing.The camera lens of imageing sensor 8 can
With the octuple of enlarged drawing.
Imageing sensor 8 can carry out size detection and color detection, can carry out two kinds of parameter detecting in detection,
And then identification is fault in material or process defect.
Encoder 9 is the yarn delivered length for measuring thread delivery device 6.The output of encoder 9 can be changed into
The length of yarn, obtains the linear velocity of yarn so as to pass through electronic controller 11.Keyboard 10 is to be input into Electronic Control for operator
11 operational order of device.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, also including keyboard, guidance panel etc..
When light passes through each pixels sense imageing sensor, it will thus provide output of the voltage in imageing sensor 8.Electricity
Sub-controller 11 is included in the controller in its memorizer, can set up the threshold value of an adjustable imageing sensor output
Level, reports Yarn detection device（Do not block）Pixel is only selected the incident illumination of the maximum possible of quantity and is connect by imaging device
The element for receiving（Pixel）.In the embodiments described, the output for each element of imageing sensor 8 is one 16
Word.
The corresponding voltage of location of pixels is that imageing sensor is defined as farthest interval foundation in yarn unit length
Output voltage.
As pixel output voltage has directly related with light amount of incident, high threshold level increase then corresponds to relatively small number of hair
The sensitivity sent out, therefore, light receives the relatively small number of information for blocking each unit.Relatively low threshold level effectively will be filtered
The intensive yarn core of hair loss amount.Therefore, threshold level can be set up a specific yarn and be tested, to reach expected test
As a result priori.
With reference to the accompanying drawings 3 and Fig. 4, the controller in the memorizer of electronic controller 11 is activated, to determine set
Width measured by threshold level is as follows.Electronic controller 11 receives the output electricity of 5096 pixels in imageing 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 blocking（Value is less than threshold value）.The signal provided by sensor can be evaluated.With reference to Fig. 2, illustrate that yarn optics is special
Property, i.e. the determination of yarn faults.Sample along the length of yarn includes two defects A and B.The color of first defect A
Similar to sample color, the color of second defect B is different from sample color.First defect A is produced can be by imageing sensor
8 detect first signal I of out of size, which is beyond that 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 imageing sensor 8, which is low
In the threshold value being set, but being similar in color in the property of sample of defect A is because, this defect is classified as defect type 1,
Which may be called for " process defect ".Second defect B produces second out of size IV detected from imageing sensor 8
Second Threshold Y is exceeded.Therefore, defect B is classified as defect type 2, and which may be called for " raw material defect ".Size detection
When, when the first location of pixels signal that electronic controller is received to imageing sensor is processed, the corresponding electricity of its location of pixels
Pressure first after height it is low carry out transition after, if during still above first threshold X, then it is assumed that size is defective；Complete basic after size detection
Color detection is carried out synchronously, when second location of pixels signal of the electronic controller to reception substantially synchronous with the first location of pixels
Processed, the first low rear height of the corresponding voltage of the location of pixels is changed, if still above Second Threshold Y, then it is assumed that color has
Defect, state of the imageing sensor by determination current pixel（Open or close）It is different from previous pixel, judge be
No is defect.Block if it is, occurring in that from unimpeded transition, or blocking, it is unimpeded.By if it is determined that previous picture
Plain voltage is greater than or less than the threshold value, and the type of transition is determined.Each of controller control represents pixel location, and mistake
The direction transition crossed.Then, controller inspection, and low transition pixel position after first height 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 by with it is many it is different in the way of be employed, if the pipe nipple of yarn is measured,
And in the relatively small number of the yarn image for shooting so that 5096 pixels of each image can be stored in electronics control
In device memorizer 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 manufacture and process operation as needed in yarn.For example, the measurement of filoplume, or integral diameter is straight with fibre core
The ratio in footpath, it can be referred to as " the filoplume factor ", can serve as a part for total grade of the yarn for manufacturing.Because measurement is certainly
It is dynamic to carry out, and the filoplume factor is calculated by electronic controller, can serve as being input to each several part of the clearing technology to remove 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 this utility model not limited to this,
In the ken that person of ordinary skill in the field possesses, may be used also on the premise of without departing from this utility model objective
To make a variety of changes, person of ordinary skill in the field is from above-mentioned design, without performing creative labour, done
A variety of conversion, all fall within protection domain of the present utility model.
