Specific implementation mode
Below in conjunction with specific embodiment, the present invention will be further described, but protection domain of the presently claimed invention not office
It is limited to range described in specific embodiment.
1 a kind of Yarn detection device with reference to the accompanying drawings is for making one fixed width yarn 3 pass through imaging area 5, and yarn is by yarn
Lines conveying equipment 6 drives.Under the action of yarn 3 is by constant tension device 4, it is maintained at a constant, repeatable tension
State and enter imaging area 5 and complete imaging.
Illuminator 2 provides the light enough in imaging area 5 so that and image arrives imaging sensor 8 by condenser lens 7, with
Realize that clearly imaging is expected.The member control apparatus 1 that shines controls the light of illuminator 2 in the method that output level controls.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, the center with 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 when detecting by waiting,
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 be converted to
The length of yarn, to obtain the linear velocity of yarn by electronic controller 11.Keyboard 10 is to input 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, further includes keyboard, operation 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 makes Yarn detection device report（It does not block）Pixel only has the incident light of the maximum possible of selected quantity to be 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.
The corresponding voltage of location of pixels is that imaging sensor is determined as farthest interval foundation in yarn unit length
Output voltage.
Since pixel output voltage has with light amount of incident directly related, high threshold level increase then corresponds to relatively small number of hair
The sensibility of hair, therefore, light receive the relatively small number of information for blocking each unit.Lower threshold level will be filtered effectively
The intensive yarn core of hair loss amount.Therefore, threshold level can establish a specific yarn and be tested, to reach expected test
As a result priori.
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 open（Equal to or higher than threshold
Value）Or it blocks（Value is less than threshold value）.The signal provided by sensor can be evaluated.With reference to Fig. 2, to 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 generations 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
Generate second signal II.If the first defect A generates first out of size III detected from imaging sensor 8, 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 generates second out of size IV detected from imaging sensor 8
It has been more than second threshold Y.Therefore, defect B is classified as defect type 2, may be called as " raw material defect ".Size detection
When, when electronic controller handles the first location of pixels signal that imaging sensor receives, the corresponding electricity of location of pixels
After pressing from low to high to carry out transition, if when 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 of reception substantially synchronous with the first location of pixels
It is handled, height is converted after the corresponding voltage of the location of pixels is first low, if still above second threshold Y, then it is assumed that color has
Defect, the state which passes through determining current pixel（It opens or closes）With the difference of previous pixel, to judge to be
No is defect.If it is, occurring blocking from unimpeded transition, or block, it is unimpeded.By if it is determined that previous picture
Plain voltage is greater than or is 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 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 applied 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 can be applied to the data of this storage, to allow yarn one-shot measurement.
The system of the present invention, electronic controller program and method ensure that the measurement of the filoplume true horizon of yarn.This
Information can be used for the manufacture in yarn and processing operation as needed.For example, the measurement of filoplume or integral diameter and core diameter it
Than 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 be automatically into
Row, and calculates the filoplume factor by electronic controller, may be used as being input to clearing technology with remove each section of yarn with not
The receivable filoplume factor improves the overall quality of yarn package.
Embodiments of the present invention are explained in detail above in association with attached drawing, however, the present invention is not limited thereto, in affiliated skill
The technical staff in art field within the scope of knowledge, can also make various changes without departing from the purpose of the present invention
Changing, person of ordinary skill in the field not inventively works from above-mentioned design, made various transformation,
It is within the scope of the present invention.
