Technical field
The present invention relates to a kind of process of dyeing, particularly a kind of detection of overflow dyeing machine water wash procedures and control method.
Background technology
In dyeing and printing process for fabrics, fabric is placed in container, and utilizes dye liquor in container to paint for fabric.After colouring step completes, dye liquor can be discharged from, and still can residual fraction dye liquor on fabric.Cleaning fabric must import the dye liquor in detersive cut-back tank and on fabric.This operation can be repeated for several times until fabric face is clean.Yet during textile dyeing, how to grasp in time the color of dye liquor? how to define in time the degree of clean fabric? the decision of these parameters is very important, because it can directly affect effect and the production cost of printing and dyeing.Traditional method is to rely on industry experience to decide number of times, deal and the cleaning time that imports dyestuff or detersive, but the operation of this dependence experience is difficult to accurately.
Find after deliberation, because common salt content in dye liquor and its concentration have direct relation, and common salt monitoring technology is also simpler, thus in printing and dyeing industry the existing common salt content of dye liquor that adopts in cleaning process in Real-Time Monitoring container with the method for the dye liquor concentration in estimation container.When the content of common salt exceeds certain level, machine can constantly move cleaning procedure until concentration is up to standard.Yet the dye liquor ratio of same deal but different colours under, its common salt content also has difference.Be two kinds of colors of same common salt content, its concentration may be different.This detection method exists major defect, can not accurately reflect the concentration of dye liquor in machine.
Therefore, in dyeing and printing process, be badly in need of very much detecting in time in a kind of printing and dyeing environment that is applicable to High Temperature High Pressure detection and the control method of dye liquor color situation.
Summary of the invention
The technical matters that the present invention solves is, overcomes deficiency and the defect of above-mentioned prior art, provides a kind of novel overflow dyeing machine water wash procedures to detect and control method.
The step of the inventive method is:
Containing the dye liquor carrying in the container of overflow dyeing machine dyeing, introduce dye liquor measurement chamber;
By emitter, send light beam, light beam is measured after the dye liquor in chamber through dye liquor, by receiving trap, is received and is collected;
Receive induction installation and be connected to master control system, the data analysis that master control system sends receiving induction installation, utilizes color data to define the concentration of dye liquor;
Master control system selects floss hole to discharge stage by stage containing the dye liquor carrying in the container of dyeing according to the concentration of defined dye liquor and other index with reference to setting value;
Master control system is controlled cleaning procedure and is stopped when the color detecting or its rate of change reach setting value.
The detection of a kind of overflow dyeing machine water wash procedures provided by the invention and control method, the light beam that described emitter is launched is the white light that LED lamp sends.
The detection of a kind of overflow dyeing machine water wash procedures provided by the invention and control method, described receiving trap is RGB sensor.
The detection of a kind of overflow dyeing machine water wash procedures provided by the invention and control method, there is valve the gateway of described dye liquor measurement chamber respectively device, when dye liquor is full of described chamber, close one period of blink and complete after the detection of dye liquor, again dye liquor is introduced and measured chamber and again dye liquor detected, so repeat, continuous detecting is measured the dye liquor in chamber.
The detection of a kind of overflow dyeing machine water wash procedures provided by the invention and control method, described dye liquor is the aqueous solution of cleaning dyeing and weaving thing.
The detection of a kind of overflow dyeing machine water wash procedures provided by the invention and control method, described setting value is by computer control and the storage of master control system.
The detection of a kind of overflow dyeing machine water wash procedures provided by the invention and control method, described step is to inject detection chambers purification of water detection chambers calibrated detector reading simultaneously before the dyeing of each batch starts with after finishing.
Unlike the prior art, the inventive method directly captures the data of dye liquor color in real time, can calculate more accurately and predict the variation in color.
Visible spectrum is comprised of Red Green Blue, and the record of color data is also usingd tri-indexes of RGB as expression way, the lifting of three indexes just can representative color the process of conversion.Such as in dyeing course, dyestuff is progressively injected in the solution of overflow dyeing machine, and the color of dye liquor is constantly to change, and from color A, finally reaches a certain color B, and two kinds of colors can be expressed by following mode:
A=(a
1,a
2,a
3)
B=(b
1,b
2,b
3)
With the form of math matrix, record respectively the RGB index of different colours, three unit in matrix represent respectively the height of tri-indexes of RGB.The R(of representative color A and color B is red respectively to suppose a1 and b1 in above matrix) index, both subtract each other the luffing of R index while just equaling color from A to B.The deal of solution and dyestuff is known, the time that adds dyeing course can be measured, from above several the factors, just can be built into a mathematical model, show the impact of different dyes on dye liquor color, to express the relation between solvent, dyestuff, time three factors and change color.Use the characteristic (variation to color index RGB) that a formula removes to express various dyestuffs and be recorded in operating system, just can calculating place dye the anticipation needed dyestuff deal of color and time.
Detecting the RGB sensor that in dye liquor, RGB index need see through in control circuit realizes.Described RGB sensor is a kind of photosensitive device, by projection white light, to detected dye liquor and gather the light beam of its refraction, converts three kinds of voltage signals (v1, v2, v3) to.By a large amount of collection data and statistical study, the height of these three kinds of voltage signals can form a numerical relationship model with the reading of RGB.The index being comprised with color A (a1, a2, a3) is example, by the expression way of function, is:
a
1=f
1(v
1,v
2,v
3)
a
2=f
2(v
1,v
2,v
3)
a
3=f
3(v
1,v
2,v
3)
In other words, controller mat reads three voltage datas, just can calculate the RGB index of detected dye liquor.Yet the light beam that is refracted to sensor can be affected by white light intensity.The dye liquor of same color, if white light intensity has change, the reading of sensor has difference, misdeems into more shallow or darker color, makes error.So the strength factor of white light is also included in described mathematical model, the RGB index that makes to calculate has comprised the offset of white light intensity, to draw data more accurately.By the expression way of function, can further understand work:
a
1=f
1(v
1,v
2,v
3,x)
a
2=f
2(v
1,v
2,v
3,x)
a
3=f
3(v
1,v
2,v
3,x)
Wherein x representative projects the required current value of white light.The power of its size of current and white light has direct relation, and size of current is a kind of circuit signal that control system can be monitored.So three voltage signals that the calculating of RGB index is sent by collecting sensor, are aided with white light current value as one of them variable in function.
The present invention detects the color situation of dye liquor in real time by detecting the RGB index of dye liquor, and realizes the control to overflow dyeing machine dyeing and water wash procedures by the computer system of control center.
In the past in rinse cycle, determine that the variation that rinsing program finished with human eye observation dye liquor color determines, even if repeatedly locate to dye batch its decision of same color and carrying capacity, be also not quite similar.The present invention adopts digitized color to represent mode, can accurately define the condition that rinsing program finishes, and only needs the dye liquor color data of setting detecting device feedback to meet some conditions, just can process more objectively the operational factor of each batch.As the destination node of rinsing program being set as to the color C:(c of certain appointment
1, c

3).When rinse cycle carries out, the concentration of dye liquor constantly declines, and color also can be thin out gradually.Until the three primary colors index c of the dye liquor color that color detector is measured and setpoint color
1, c
2, c
3coincide, system just defines finishing of rinsing program, carries out and the program relevant action that finishes, for example, close the valve of injection detersive.
