The specific embodiment

With reference to figure 1, as seen:

A dyeing machine 100 by program controller 105 controls, dye liquor is filled with and is dyed pond 110 in dyeing course, this dyeing machine makes and dyes the pond around base cloth or wait to dye bobbin circulation, dye the circulation 120 that produces in the pond and make the dye liquor motion, this dyeing machine comprises water pump 122, and one derived and refill the pipeline 124 that dyes pond 110 with dye liquor from dying pond 110

An analysis room 130, the piston 132 that comprises motor 134 drivings that are installed within the fabric guide roll 133, the piston 132 that transparency sensor device 140 that light source 142 is housed is moved, light source 142 by power supply 111 (Fig. 4 A is to 4G) power supply, and fibre bundle 144, the sensor 146 that links to each other with analog-digital converter 148 has been aimed in its outlet

Gearshift 136, at fibre bundle 144 to (referring to Fig. 4 A to 4D, and Fig. 4 E is to the variable of 4G) between the path of light source 142,

Controlling organization 149, it comprises:

A signal analysis device 150 is used to receive the data signal that analog-digital converter 148 sends, and an analysis result is provided,

A servomechanism installation 160 that is used to dye the acidity and/or the salinity in pond,

A temperature servomechanism installation 162 that is used to dye the pond,

A servomechanism installation 164 that is used to dye pond 110 clear water inlet,

One is used for to the servomechanism installation 166 that dyes pond interpolation dyestuff,

A command device 170 that is positioned on the motor 134, motor 134 is loaded on the piston 132, and

Command device 172 on the gearshift 136, and

The switching device shifter (figure does not show) that program controller 105 is housed is used for carrying out the exchange of dyeing machine service data, and makes program controller 105 can store or transmit the trackability of dying operation (tracabilit é) data.

Dyeing machine 100 and the composition that dyes pond 110 are the known models of textile industry.The place of dyestuff input should preferentially be positioned near the inlet that dyes pond 120, and dyestuff just is dissolved in the water at the contact base cloth or before waiting to dye bobbin.If the place of dyestuff input on pipeline 124, so, flows to according to the liquid circulation in this pipeline 124, the analysis room should be positioned at its upstream.

A lot of dyeing machines all comprise the circulation in the pond 120 of having illicit sexual relations.The model of water pump 122 and pipeline 124 is known, and a lot of dyeing machine has.They are used for guaranteeing base cloth and dye the relative motion in pond.They dye the pond or can not cause the material of profiling error to be made by not polluting.Water pump 122 preferably has firm discharge, if necessary, can regulate flow.

Fabric guide roll 133 has constituted transparency sensor 140 positioner on the liquid circulation 120 in dying the pond.This positioner has the support that is fit to above-mentioned circulation, and such as punching on pipeline 124 earlier, the connector that adopts gummed, riveted then and/or be screwed (not introducing) is perhaps changed a member on the pipeline 124.

Positioner also comprises a gearshift 132 on the sensor 140, makes on the initial circulation of sensor liquid in dying the pond or its outside moving, and initial circulation is then by pipeline 124 decisions.

In example shown in Figure 1, above-mentioned gearshift has a piston 132 that becomes horizontal placement with liquid circulation.

Analysis room 130 is made of a part and the piston 132 of pipeline 124, and the motor of being controlled by command device 170 134 drives.Rely on this piston mechanism, need not to be equipped with special pipeline into the Dye-vat Control device.Therefore, complexity, manufacturing cost, installation cost and the maintenance cost of this device manufacturing all can reduce greatly.

When piston 132 is in expanded position (or high point), transparency sensor 140 will be positioned at analysis room 130.This analysis room include over against light source 142 and fibre bundle 144, promptly be positioned at the analysis room 130 (Fig. 1,4A, 4C and 4D) on the pipeline 124.Analysis room 130 also comprises the gearshift that begins to lead to light source 142 from fibre bundle 144.Such as, gearshift 136 comprises a stepper motor by command device 172 controls.The interval that the entrance point of fibre bundle 144 and light source are 142 preferably changes in the scope of 0.1mm to 7mm at least.

When piston 132 was in recovery position (or low spot), transparency sensor 140 was positioned at outside fabric guide roll 133 places, the pipeline 124, and faces the clear water current of inlet and outlet piping 175.

Water circulation in the pipeline 175 has two effects.It can clean transparency sensor 140, particularly its optics.In addition, as a kind of replacement scheme, this circulation also can be used for the mensuration of clear water transparency.

This circulation by electrically operated valve 174 controls can be controlled by the program controller 105 of controlling organization 149 (as shown in Figure 1), dyeing machine 100, perhaps as a kind of replacement scheme, is manually controlled by operating personnel.

As a kind of replacement scheme, the valve that piston can be used as pipeline 175 uses, and need not to use electrically operated valve.

Light source 142 can be the photodiode of an incandescent bulb, a Halogen lamp LED or the coloured light that turns white.It is signal digitalized that the analog-digital converter 148 of known models can be exported sensor 146.This digitized process can carry out on the circuit such as visible light in spectral region of expression.This digitized process also can carry out on many circuits of the different spectral regions of expression, such as ruddiness, green glow and blue light.Afterwards, comprise that the sensor 146 of a plurality of sensors is just had an effect in different spectral regions, such as by being furnished with the optical fiber of known models, every circuit can link to each other with one of them sensor.

Digitized process also can carry out on an analog-digital converter.By a multiplexer, this analog-digital converter links to each other with each sensor that is used for peculiar spectrum scope measurement (such as ruddiness, green glow and blue light), perhaps has how many sensors just to be equipped with how many analog-digital converters.

Signal analysis device 150 is used to receive the data signal of analog-digital converter 148 outputs, and according to logic chart shown in Figure 2, this signal analysis device carries out following operation:

The transparency sensor is demarcated, then

Analysis result is provided, and its form is the transparence value of used spectral region,

During dyeing, the comparison of each transparence value derivative and at least one pre-set limit value is provided, if necessary, can provide the function that dyes pond composition and/or its reference point, and,

Between flush period, the comparison of each transparence value derivative and at least one pre-set limit value is provided, if necessary, can provide the function that dyes pond composition and/or its reference point.

We find that the pre-set limit value may change with the spectral region of considering.As a kind of replacement scheme, during dyeing, signal analysis device 150 can compare transparence value and pre-set limit value, if necessary, can provide the function that dyes pond composition and/or its reference point.Equally, as a kind of replacement scheme, in rinse stage, signal analysis device 150 can compare transparence value and pre-set limit value, if necessary, can provide the function that dyes pond composition and/or its reference point.

Signal analysis device can be a computer through programming, operates by process shown in Figure 2.It has the user interface (figure does not show) of a band screen, a keyboard, if necessary, also needs a bearing unit, as mouse.

Dye the acidity and/or the salinity servomechanism installation 160 in pond, dye the temperature servomechanism installation 162 in pond, the servomechanism installation 164 of clear water water inlet and dyestuff input dyed the servomechanism installation 166 in pond, will be according to the result that signal analysis device provided, respectively at least one operation of dying pond chemical addition agent input valve is controlled, dyed Chi Shuliaofamen such as the operation of the thermal source that constitutes by heat exchanger or jet chimney, clear water inlet valve and one.We find that word " valve (vanne) " does not preestablish the state (liquid, solid or gas) of dyestuff and/or other chemical addition agent, also can inject such as alkali and dye the pond.

With reference to the accompanying drawings, we can find, if dyestuff just will treat that the dyeing and weaving fibres is placed in the dyeing machine before injecting, and dyestuff may cause " first strike (first strike) " phenomenon, and device production method then shown in Figure 1 will carry out the change of step.The workman of the industry can be easy to adapt to following other operating procedures of dyeing machine.Therefore in this explanation, just no longer describe in detail.

We admit that dyeing machine is that clear water injects in elder generation and other have the reagent that is beneficial to the smooth expansion of dyeing course when beginning.This pond of dying of still not having dyestuff just is called " Bai Chi ".We admit that also original white pond has reached the dyeing temperature that needs.Otherwise when injecting clear water, we will heat to dying the pond, reach required temperature up to it.

In the stage 200 that commercial run is selected, user's selective staining method provides simultaneously and waits to dye the weight of material, the sign of used one or more dyestuffs, and needs injection to dye the dye quantity in pond.In the stage 202, the dye quantity that we dye the pond according to the dyestuff and the needs injection of selection comes the transparency sensor is controlled with respect to the displacement of light source.

As a kind of replacement scheme, specified data above must having all will be carried out the transparency of Bai Chi and be measured for each preset thickness (such as three).Mensuration contain dyestuff dye the pond transparency time, for each preset thickness, we will carry out transparency and measure.

As a kind of replacement scheme, during dyeing, we are according to the measured value of transparency, make the water sample thickness that is used to measure transparency change with the variation of measured value, and then according to water sample thickness, use the correction factor of a measured value.

So far, just all automations of device of the present invention.

In the stage 203, because sensor is positioned on the pipeline 124 of high point, we allow the water circulation in the preceding white pond of sensor flow, and after transparency sensor 140 cleans a period of time, the transparency of clear water mobile in transparency sensor 140 (in each used spectral region) is measured.Preferably can obtain many digital values, and with their average (after getting rid of presumable extreme value) away from mean value as the result who measures, with this as the complementarity reference point of dying the pond transparency change (" measured value of Bai Chi ").

In the stage 204, our control piston 132 allows it rise, and transparency sensor 140 is positioned on the circulation that dyes pond 120.

As a kind of replacement scheme, as to only the replenishing of stage 203 that transparency sensor 140 wash phases use, in the stage 205, sensor is placed low level, be positioned on the pipeline 175, and clear water flowed in sensor the place ahead.In the stage 210, clear water flows through analysis room 130, and we measure the transparency of clear water mobile in transparency sensor 140.Preferably can obtain many digital values, and with their average (after getting rid of presumable extreme value) away from mean value as the result who measures, with this as the complementarity reference point of dying the pond transparency change.Dyestuff inject dye the pond before, when having added a kind ofly may cause the chemical composition of dying the pond transparency change time, preferably use this variable to dying the pond.

After

stage

203 or 205 finished, in the stage 215, analytical equipment can be stored the corresponding measurement result of clear water or white pond transparency.This measured value is called " Bai Chi " measured value.

Then, in the stage 220, we make and dye the pond (cloth or line) moves with respect to treating the dyeing and weaving fibres, and beginning injects dyestuff to dying pond (initially being made of Bai Chi), may also can add to be used for promoting or the chemical addition agent of additional textile dyeing.In the time D during the stage 220, analytical equipment can be stored the change of representative value of the transparency (in the spectral region of each use) of analog-digital converter output.(such as Fig. 4 A to shown in the 4D, three spectral regions in the visible range).

After the initial injection of dyestuff and chemical addition agent is finished, in the stage 225, analytical equipment will be determined at least one used spectral region:

The reference point of the formed curve of value that each spectral region will reach (Fig. 3, reference point 315), and

" first strike " rate (we gallice are expressed as " cold dyeing ") of each spectral region.

When not being absorbed as yet, the reference point 315 best corresponding time D inner dyes that dye the pond transparency change dye the pond transparency.

If with fixing flow the circulation in pond 120 is dyed in the dyestuff injection, then there is transparency sensor 140 upstream.Under the definition mode of this situation of being fit to, what the reference point of curve was at first approached is the transparence value (arranging in order) at the last point of contact of transparency curve (referring to Fig. 3), this transparency curve is with changing in time when beginning to inject dyestuff and change, and to dye the point (abscissa) of pond when finishing corresponding and this point of contact and dyestuff inject.

If with fixing flow the circulation in pond 120 is dyed in the dyestuff injection, then there is transparency sensor 140 upstream.Under the definition mode of this situation of being fit to,,, determine the reference point that indicates above as the described tangent slope of above chapters and sections with using first amplification coefficient of determining by experience.Such as, if tangent slope equals at-4% o'clock of initial transparency (" Bai Chi ") value that the per minute dyestuff injects, then this tangent slope is-5%, like this, for treating dyeing and weaving thing and the initial temperature and the pH value of dying the pond, we just can inject the incipient stage of dyeing machine at dyestuff, are dying before the pond flows to the transparency sensor, and defining 20% dyestuff can be absorbed by this fabric.If with fixing flow the circulation in pond 120 is dyed in the dyestuff injection, then there is transparency sensor 140 upstream.

Under the definition mode of this situation of being fit to,,, determine the reference point that indicates above as the slope of every bit on the above-mentioned tangent line with using second amplification coefficient that is inversely proportional to the dyestuff instantaneous delivery.Such as, if tangent slope equals-4% of initial transparency (" Bai Chi ") value that the per minute dyestuff injects, flow is 1 liter of a per minute, when flow was 0.5 liter of a per minute, during the injection of per minute dyestuff, this tangent slope will reduce-2%.Therefore, can determine the transparency of reference point (abscissa) by the alternate linear interpolation.

Variable as definite mode of these different reference points, in time D, we use a non-linear interpolation of considering used physical phenomenon at least, and (such as a fabric that changes with the absorption that has taken place to the absorption coefficient of dyestuff and/or the ability that can be absorbed by fabric with the dyestuff that dyes pond inner dye change in concentration) and dyeing parameter (such as the pH value and the temperature of dying the pond) are determined reference point.

No matter adopt any method to determine reference point 315, " first strike " rate all equals following ratio:

The transparency of reference point representative and dyestuff inject the difference of the transparency on the curve when finishing, divided by

The difference of clear water (" Bai Chi ") transparency and reference point (arranging in order) transparency.

Such as, if the initial transparency of injecting when finishing equals the transparency of reference point, " first strike " rate is zero so.

Equally, the transparency when we inject beginning to dyestuff is at least carried out interpolation one time, preferably linear interpolation, and the transparency reference point when injecting end with definite dyestuff, and then determine " first strike " rate.

If " first strike " rate is greater than preset value, such as 40%, we will send an alarm signal to the user, revolve flashing light and/or ring such as on a user interface, showing an information (figure does not show) or starting, thereby make operating personnel can recognize the danger of fabric uneven dyeing, consider to stop the dyeing process, emptying is dyed the pond and is treated the dyeing and weaving thing and begin dyeing cycle again on other base cloth, or the operational factor of change dyeing machine 100, as the injection length D of the base cloth that dyeing, or the same weight of next group, use the injection length D of the base cloth of identical dyestuff.

As a kind of replacement scheme, in the stage 225, we can estimate first strike value or first strike rate in time D, if the absolute value of this first strike value or first strike rate greater than pre-set limit, we will reduce the dyestuff flow that injects dyeing machine.Therefore, controlling organization 149 just can be controlled the dyestuff flow that injects dyeing machine according to dying clarity of liquor situation of change in the pond.

In the stage 230, we get rid of each transparency change value in the stage 220 less than the spectral region of default rate of change (such as 30%).As a kind of replacement scheme, be used alternatingly above-mentioned exclusive method, perhaps when it had kept at least one spectral region, we just got rid of the spectral region (such as) of predetermined number.In the stage 220, the transparency change value in these spectral regions that are excluded is the faintest.

We observe, and significant spectral region is the complementary light spectral limit of the transparency spectral region of used dyestuff normally.We also observe simultaneously, and multiple dyestuff can act on fiber to be dyed respectively, and can exert an influence to multiple different spectral region.

Then, in the stage 230, at least one spectral region that is not excluded and spectral region that each need be considered, we will measure the transparency of one-period.The difference that we will go up the value that records and curve (changing in time) given rated value compares.This curve is to calculate the default nominal curve that draws according to first strike value or first strike rate with white pond or clear water transparency under preset value.If the difference of rated value and measured value is less than preset value, we just enter the stage 240.

As a kind of replacement scheme, we carry out the operation in stage 230 to the water sample that each preestablishes thickness, and then, we select and both avoid sensor saturated, meet the measured value of optimal dynamic again.

Otherwise in the stage 235, we control:

A servomechanism installation 160 that dyes the acidity and/or the salinity in pond,

A temperature servomechanism installation 162 that dyes the pond,

Servomechanism installation 164 that dyes pond clear water inlet and/or,

One to dying the servomechanism installation 166 that dyestuff is added in the pond,

So that the recovery dyeing course, thereby make transparence value near default nominal curve.According to known automaton, we get back to the stage 230.

Such as, if what the transparency that records with sensor 140 was represented dyes the pond emission index less than the rated value that provides on the nominal curve, then well-known, we can begin to heat or change its pH hydrogen ion exponent to dying the pond, thereby improve or reduce the speed of dying the pond discharging.

As a kind of replacement scheme, in the stage 235, we start an information warning (representative dyeing anomalous signals) at least, as visual alarm (such as revolving flashing light) or audible alarm (such as ring), so that give the alarm to operating personnel or information system, thereby both can guarantee trackability, also can revise the operational factor of dyeing machine, thereby reduce the adverse consequences that this may cause unusually.

In the stage 240, we will determine the transparency change value of in a Preset Time (such as a minute).Then, in the stage 245, we compare this changing value and a preset value.This preset value is the value of reference point 315 and the function of clear water (" Bai Chi ") calibration value preferably.If changing value is greater than preset value, we just return the stage 230 so.Otherwise, can think that dyeing course finishes, we just provide a signal to the user, point out that dyeing course finishes, such as the passage on the user interface.In the stage 250, the user begins fabric is washed, and the pond is dyed in emptying simultaneously, and continues to inject clear water.As a kind of replacement scheme, in the stage 250, we will begin flushing automatically.

In the stage 255, for each spectral region that is not excluded (referring to the stage 230), the difference of a value that we will record and a flushing rated value compares.At last, this flushing rated value curve is to determine according to the transparency and/or a default nominal curve in the clear water transparency that records in the stage 215 (" Bai Chi "), when beginning flushing.Such as, the flushing rated value equals the transparence value that records in the stage 215.If the difference of rated value and measured value is less than preset value (such as 2%), we just enter the stage 260.

In the stage 260, we will determine (such as 15 seconds) transparency change value in a Preset Time.Then, in the stage 265, we compare this changing value and a preset value.This preset value is preferably determined according to the transparency and/or a default nominal curve in the clear water transparency that records in the stage 215 (" Bai Chi "), when beginning flushing.If changing value is greater than preset value, we just return the stage 255 so.Otherwise, can think that dyeing course finishes, we just provide a signal to the user, show that dyeing course finishes, such as the passage on the user interface.In the stage 270, the user begins to stop fabric being washed.As a kind of replacement scheme, in the stage 270, we will stop to wash automatically, stop to inject clear water and stop to dye cloth or the motion of fiber, and emptying dyeing machine 100.

As a kind of replacement scheme, we can omit in

stage

255 or 265 one.The changing value of determining when stage 265 is less than stage 265 (omission stage 255) during preset value, can think that flushing finishes; The changing value of determining when stage 255 is less than stage 255 (omission stage 265) during preset value, can think that also flushing finishes.

When taking to overflow flushing, also can operational phase 250 and above-mentioned steps.

As a kind of replacement scheme, be applicable to periodically flushing, in the stage 275 after the stage 245, we begin first flushing cycle: the emptying dyeing machine, and fill with clear water.

When dyeing machine was filled with clear water, in the stage 280, for each spectral region that is not excluded (referring to the stage 230), the difference of a value that we will record and a flushing rated value compared.This flushing rated value curve is preferably according to the clear water transparency that records in the stage 215 (" Bai Chi "), and the transparency during the flushing beginning and/or default nominal curve are determined.Such as, the flushing rated value equals the transparence value that records in the stage 215.If after Preset Time finished, the difference of rated value and measured value was less than preset value, we just enter the stage 285.Otherwise we are with regard to duplication stages 275.

In the stage 285, we will determine (such as one-period) transparency change value in a Preset Time.Then, in the stage 290, we compare this changing value and a preset value.This preset value is preferably determined according to the transparency and/or a default nominal curve in the clear water transparency that records in the stage 215 (" Bai Chi "), when beginning flushing.If changing value is greater than preset value, we are with regard to duplication stages 275 so.Otherwise, can think that dyeing course finishes, we just provide a signal to the user, point out that dyeing course finishes, such as the passage on the user interface.In the stage 295, the user begins to stop fabric being washed.As a kind of replacement scheme, in the stage 295, we will stop to wash automatically, dwelling period injection clear water and stopping to be dyed cloth or the motion of fiber, and the emptying dyeing machine.

As a kind of replacement scheme, we can omit in

stage

280 or 290 one.The changing value of determining when stage 290 is less than stage 290 (omission stage 280) during preset value, thinks that flushing finishes; The changing value of determining when stage 280 is less than stage 280 (omission stage 290) during preset value, thinks that flushing finishes.

As a kind of replacement scheme, in rinse stage and/or dyeing stage, the thickness that we make water sample that need to measure transparency changes with the transparency change of flushing liquor or dyeing liquor, preferably measured value is used a correction factor.We just can make the measured value of transparency keep higher accuracy like this.

We observe, and are having under the situation of demonstration, and what we preferably showed is the change curve of dye strength.This curve is used Bert-lambert (Bert-Lambert) theorem and is obtained.

What Fig. 3 showed is that a value that reaches measurement device shown in Figure 1 or calculating in time changes and the transparency curve of variation.What this device used is logic chart shown in Figure 2:

The measured value of curve 300 expression transparencies;

The straight line of tangent line 310 expression regulation reference points 315;

320 are illustrated in the time D, the stage that dyestuff injects;

The dyeing ending phase of 330 expression regulations;

The flushing ending phase of 340 expression regulations; And

The complementary reference point of 345 expression clear water (" Bai Chi ") transparencies.

The abscissa value that we observe reference point 315 is used as the zero point of other abscissas.Preferably, determine default transparency change value or absolute value according to the transparency of reference point on the other hand on the one hand according to clear water (" Bai Chi ") transparency.

Such as, the dyeing ending phase emission index of wishing (using in the stage 230) is corresponding is 30% transparency of clear water (" Bai Chi ") the transparency difference that deducts clear water transparency and reference point 315 transparencies (abscissa).

Such as, in five minutes period, the dyeing ending phase transparency of wishing (using in the stage 240) is corresponding is 2% transparency of the difference of clear water (" Bai Chi ") transparency and reference point 315 transparencies (abscissa).

Such as, the dyeing ending phase transparency of wishing (using in the stage 280) is corresponding is 2% the transparency that clear water (" Bai Chi ") transparency deducts clear water transparency and reference point 315 transparencies (abscissa) difference.

Such as, in five minutes period or in flushing cycle, the dyeing ending phase is wished dye pond transparency (using in the stage 290) corresponding be 1% the transparency that clear water (" Bai Chi ") transparency deducts clear water transparency and reference point 315 transparencies (abscissa) difference.

We observe, in the example that Fig. 3 enumerates, dyeing finishes determine and flushing to finish to establish a capital really be that transparency change value by measuring in the certain hour is determined.These two values are all less than preset value.

We observe method and apparatus of the present invention and can be used as a kind of replacement scheme, can analyze and dye the pond transparency change, and what analyze or rather is the variation of dying pond inner dye concentration.In this case, according to known technology, preferably use Bert-lambert's theorem (Bert-Lambert) to come definite dye strength with transparency change.

Or rather, the curve correspondence that Fig. 3 represents be to adopt to overflow the curve of flushing, rather than adopt the periodically curve of flushing.Under the situation of employing cycle flushing, the transparency change value in the flushing process should have flex point.Therefore should be a curve that " gradient " arranged, that is to say, the transparency change situation of (when periodic transformation) and slow (in one-period) rapidly alternately occur.

In 4G, we have only described to use the sensor of three spectral regions at Fig. 4 A.In other designs, can use wider spectral region.

In Fig. 4 A, we observe, and when piston 132 stretched out, sensor was positioned on the circulation 120, and the water sample thickness of being controlled by motor 136 is a mean value (such as 0.9mm).

In Fig. 4 B, we observe, and when piston 132 withdrawals, sensor is positioned at outside the circulation 120, and clear water flows in pipeline 175.We observe, and in order to remove the fabric fibre that may snarl transparency sensor 140, with respect to the flow direction of transparency sensor 140, clear water flows to best with to dye the pond opposite.

In Fig. 4 C, we observe, and when piston 132 stretched, sensor was positioned on the circulation 120, and the water sample thickness of being controlled by motor 136 is a minimum of a value (such as 0.1mm).

In Fig. 4 D, we observe, and when piston 132 stretched, sensor was positioned on the circulation 120, and the water sample thickness of being controlled by motor 136 is a maximum (such as 7.2mm).

We observe best basis significantly geometric progression define thickness, that is to say that the ratio of two adjacent thickness obviously is (being 9, then is 8 below) of fixing here.

In Fig. 4 E, we observe, and light source 142 has three beams optical fiber 144A, 144B and 144C.These optical fiber are installed by different distance over against light source, such as 0.2mm, 1.2mm and 7mm, and adopt tabula rasa (figure does not show) to separate mutually from optics.The other end of each optical fiber faces toward:

Such as, a phototransistor 405 that is used to survey blue light wavelength

Such as, a phototransistor 410 that is used to survey red light wavelength, and

Such as, a phototransistor 415 that is used to survey green wavelength.

Transistor 405 (410 and 415) is preferably parallel to be placed on after the same interference filter, over against corresponding fibre bundle, and optically separates with other fibre bundles, thereby avoids cross influence.

The power circuit of phototransistor is to be controlled according to the change in signal strength that phototransistor receives by multiplexer (not describing in detail).The phototransistor output port links to each other with analog-digital converter (be not connected and introduce) by multiplexer 425.In order to optimize the signal quality that receives, can selective channel A, B or C.If necessary, can carry out the selection of channel according to one or more dyestuffs of identification use and the dye quantity of stages 200 domestic demand injection.

As a kind of replacement scheme, the whole fibre bundle of corresponding same thickness leads to same imageing sensor, closes the sensor of element (the electric charge lotus root in DTC or the English is closed element (charge coupled device) or CCD) or be furnished with the C-MOS of colouring filter device such as being furnished with the electric charge lotus root.

In Fig. 4 F, we observe, and fibre bundle 450 is installed on the pipeline 124 and faces toward prism 452.Prism 452 is parts of continuous two mirrors, and the axle of this continuous mirror and illumination fiber optic bundle 450 and the fibre bundle axle of fibre bundle 458 become miter angle respectively, its outlet over against:

A phototransistor 460 that is used to survey blue light wavelength

A phototransistor 461 that is used to survey red light wavelength, and

A phototransistor 462 that is used to survey green wavelength.

The light of fibre bundle 450 emissions is through the porch of prism 452 guiding fiber bundles 458.

The phototransistor output port links to each other with analog-digital converter by multiplexer 465.

In Fig. 4 E and 4F, we have introduced the transparency sensor of three phototransistors (each water sample thickness is used three spectral regions).But whether no matter in visible-range, the number of the present invention and used spectral region is irrelevant.Such as, we can use four spectral regions by four determined visible lights of interference filter.

In Fig. 4 G, we observe, imageing sensor 500 in analysis room 130, as the C-MOS imageing sensor (with the electric charge lotus root close element compare have very high innervation), facing to light source 510, outlet or a photodiode as a fibre bundle, like this, the pixel (or pixel) according to image sensor surface can make light source be in different distances, and/or, light source is at least in from one to ten the proportion according to different solid angles.Such as, light source is positioned at the 0.2mm place of one jiao of range image sensor, thereby makes relative one jiao of several millimeters place that are positioned at light source.We will handle image, so that select to utilize the signal that dynamic image sensor pixel is sent in the imageing sensor, and these signals are not subjected to the too strong pixel influence of illumination, thereby determine to dye the transparency in pond.

We observe, and we can use an imageing sensor of being explained as Fig. 6 B.This imageing sensor is furnished with colouring filter device or the light source that can launch light in the different spectral regions continuously.

If what use is the sensor of a C-MOS sensor or other any models, in these sensors, illumination change along with each point, electric charge gathers on the pixel of imageing sensor, and electric charge is the pointwise addressing in sensor, and we preferably eliminate apart from the electric charge on the nearer image sensor pixel of light source usually, rather than apart from the electric charge on the light source image sensor pixel far away.Such as, concerning each image sensor pixel, the elimination frequency of electric charge is relevant with the illuminance of these points.Like this, the destruction that the brightest point just can not be subjected to excessive charge, and also they also can not produce interference to the measurement of transparency.

If necessary, we can increase some measurement points corresponding with image sensor pixel, thereby improve the signal to noise ratio of measured value.These pixel utilizations be the identical dynamic part of sensor.

Viewed in Fig. 4 G at Fig. 4 A as us, controlling organization 149 also comprises the susceptibility control device 136 of sensor 140, and sensor 140 changes according to the liquid opacity of dying in the pond.

In the drawings under the situation of Jie Shaoing:

Controlling organization 149 also comprises servomechanism installation 136, and this servomechanism installation changes according to the variation of dying the liquid opacity in the pond, is used for dying the light path that light passed through of the liquid sensor emission in the pond;

One is dyed pond water sample thickness adjusting apparatus (being gearshift 136) here, by controlling organization 149 controls.Its transparency is recorded by the transparency sensor, thereby water sample thickness is directly proportional with the transparency of dying the pond;

Thickness adjusting apparatus can make light source and at least one optical fiber move mutually;

As a kind of replacement scheme, the controlling organization 149 shown in Fig. 4 G comprises:

A servomechanism installation, this device changes according to the variation of dying the liquid opacity in the pond, is used for the sensor detection time, and/or

A servomechanism installation changes according to the variation of dying the liquid opacity in the pond, and the signal to noise ratio that is used for sensor output signal is amplified.

As a kind of replacement scheme, different implementations according to above introduction, we can use at least two over against sensor, can launch the light source of different light quantities, and transparency according to hope, perhaps dye the transparency measured value of pond or flushing, control the conversion equipment that an above-mentioned light source is opened.

In Fig. 5, we observe, and have used the present invention's device 500 in a certain respect at least for one, link to each other with a dyeing machine 505, and fill with and dye pond 510, and this device 500 comprises:

Article one, dye pond circulation 520, it is furnished with a water pump 522 and a pipeline 524, be used for getting liquid and flowing back to again and dye pond 510 from dying pond 510,

, a clear water circulation 536, it is with to dye pond circulation 520 parallel;

An activity analysis chamber 530, it is positioned on the piston 532 that the motor 534 by fabric guide roll 533 drives, and has transparency sensor 540.This transparency sensor has light source 542 (referring to Fig. 6 A and 6B), and at least one optical fiber 544, and its outlet faces the sensor 546 that links to each other with analog-digital converter 548;

Controlling organization 549 comprises:

A signal analysis device 550 is used to receive the data signal that analog-digital converter 548 sends, and an analysis result is provided,

A servomechanism installation 560 that dyes the acidity and/or the salinity in pond,

A temperature servomechanism installation 562 that dyes the pond,

The servomechanism installation 564 of a clear water inlet,

One to dying the servomechanism installation 566 that dyestuff is added in the pond,

A multiplexer 568 can be controlled the light of the different spectrum that light source 542 sends, and can transmit an information separated signal by signal analysis device 550, and

The command device 570 of the motor 534 of a piston 532.

Dyeing machine 505 and the composition that dyes pond 510 are the typical models of textile industry.A lot of dyeing machines all are furnished with the pond of dying circulation 520.The model of water pump 122 and pipeline 124 is known, and dyes the pond or can not cause the material of profiling error to be made by not polluting.Water pump 122 preferably has firm discharge, can regulate flow if necessary.

By motor 534 activity analysis chamber 530 is moved at least on three positions.In first position, promptly high-order, activity analysis chamber 530 contacts with the fluid that dyes pond circulation 520, and collects one and dye the pond water sample.Second position, it is meta, activity analysis chamber 530 neither contacts with the fluid that dyes pond circulation 520, do not contact with the fluid of clear water circulation 536 yet, thereby can leave standstill water sample, bubble in the water sample can be disappeared beyond the light field of sensor 546, and the transparency sensor just can be measured on each significant band.The 3rd position, i.e. low level, activity analysis chamber 530 contacts with the fluid of clear water circulation 536, and cleans water sample.

Rely on this piston mechanism, need not to be equipped with special pipeline into the Dye-vat Control device.Therefore, complexity, manufacturing cost, installation cost and the maintenance cost of this device manufacturing all can reduce greatly.

In analysis room 530, the distance between fibre bundle 544 and the light source is fixed, and it is preferably in 0.2mm at interval in the scope of 7mm..

Under the control of multiplexer 568, light source 542 can be launched the light of different bands continuously.Have multiple photodiode such as light source 542, the spectrum summation of its emission can cover visible-range (referring to Fig. 6 A) at least.As a kind of replacement scheme, light source 542 comprises a photodiode, and the spectrum of its emission changes (referring to Fig. 6 B) along with the variation of the characteristic of the electricity that applies to it.Such as, the voltage that applies to light source 542 can make the spectrum of its emission change.

As a kind of replacement scheme, light source 542 can be incandescent bulb or halogen lamp.We apply a variable voltage to it, make the spectrum of emission change in an analytical cycle.The analog-digital converter 548 of known models is signal digitalized with sensor 546 outputs.

The signal analysis device 550 of the data signal that reception analog-digital converter 548 is exported, what use is that logic chart shown in Figure 7 comes the transparency sensor is demarcated, then according to the signal that is separated in the signal by analog-digital converter 548 outputs, analysis result is provided, its form is the transparence value in each used spectral region, and this value is with the comparison of pre-set limit value.The preset range value changes with dying the variation of forming in the pond.Signal analysis device 550 can be a computer through programming, can carry out the operation of process shown in Figure 7.It has a user interface (not describing in detail) and a keyboard of being furnished with screen, if necessary, also has a bearing unit, as mouse.

The result who provides according to signal analysis device, dye the acidity and/or the salinity servomechanism installation 560 in pond, dye the temperature servomechanism installation 562 in pond, the servomechanism installation 564 of clear water water inlet and dyestuff input dyed the servomechanism installation 566 in pond, control the operation that at least one dyes pond chemical addition agent input valve respectively, such as the operation of the thermal source that constitutes by heat exchanger or jet chimney, a clear water inlet valve, one is dyed Chi Shuliaofamen.We find that word " valve " does not preestablish the state (liquid, solid or gas) of dyestuff and/or other chemical addition agent, also can inject such as alkali and dye the pond.

We observe, and by signal analysis device 550, to the operation that these different driving devices described above carry out, can be undertaken by an outside program controller of device.Usually had program controller on the dyeing machine.This other program controller is used for after programming according to the signal of signal analysis device 550 outputs, accessory drive.

In Fig. 6 A, we observe, and activity analysis chamber 530 is in the piston 532 that motor 534 drives.In Fig. 6 A, light source 542A comprises seven photodiodes 605.They become quincunx arrangement, and wherein Zhong Yang six diodes of a diode and other contact, and these six diodes have been formed a ring equidistant with central diode.The spectrum summation of photodiode 605 emissions can cover visible-range (referring to Fig. 6 A) at least.Such as, the spectral width of each diode 605 is about 50 nanometers.

Because the axle of photodiode all points to the center of optical fiber 544 inlet faces, so all diodes 605 obviously can cover the same solid angle that optical fiber 544 porch center on.

In Fig. 6 B, we observe, and activity analysis chamber 530 is in the piston 532 that motor 534 drives.In Fig. 6 B, light source 542B has only a photodiode 655.It is over against the inlet of optical fiber 544, and applies a zigzag synchronous voltage signal by multiplexer 568 to it.The photodiode 655 spectrum summation of emission continuously can cover visible-range at least.

We observe, and shown in Figure 7 is the one-time continuous service chart of each step of Fig. 5,6A and 6B shown device implementation.

In the stage 700 that commercial run is selected, user's selective staining method provides the weight of waiting to dye material simultaneously, the sign of one or more dyestuffs of use, and the quantity that needs to inject the dyestuff that dyes the pond.As a kind of replacement scheme, explain as Fig. 2, do not use these data.In the stage 702, the displacement of our control piston 532 and position are to determine that transparency sensor 540 is in the position of dying on the pond circulation 520.

In the stage 704, we begin to inject clear water to dye liquor tank.As a kind of replacement scheme, the stage 706 can replace stage 702 and 704.In the stage 706, the displacement of our control piston 532 and position, determining transparency sensor 540 in the position of dying on the pond circulation 520, and the later stage 718.

In the stage 710, clear water (or " Bai Chi ") analysis room 530 that flows through, and in continuous seven stages (711 to 717), it is luminous in seven different spectrum or transmitting boundary that multiplexer 568 is controlled light source 542 in succession.These spectrum preferably can cover whole visible spectrum.For each emission spectrum, in identical time interval, analytical equipment can be stored the value that the interior analog-digital converter of clear water flushing time section is exported after light source is opened.Initial and the time limit in this time interval can change with the variation of emission spectrum, launches the poor of luminous energy and sensor sensing degree in the different spectral regions such as compensating.

Preferably can obtain many digital values, and their average (get rid of some may away from the extreme value of mean value) is stored as the measurement result of each spectral region.

In the replacement scheme stage 718, the displacement of our control piston 532 and position are to determine that transparency sensor 540 is in the position of dying on the pond circulation 520.

Then, in the stage 720, we begin to inject dyestuff in dying the pond, if necessary, also may add being used for promoting or the chemical addition agent of additional textile dyeing in dying the pond.We begin dying the pond heating.In the time D in stage 720, we carry out a plurality of sampling periods, in the high position of piston, water sample are left standstill; At the meta of piston, the transparency of the different spectrum of measurement light source emission; At the low level of piston, water sample is discharged in the transparency sensor.

For each cycle, analytical equipment can be stored the digital value of each emission spectrum that light source sends.These emission spectrum are controlled by multiplexer 568, and guarantee that simultaneously the time interval of use is identical with Preset Time from the stage 711 to 717.And corresponding emission spectrum that defined of each time interval:

Spectrum according to multiplexer 568 control emissions changes to the interval that this time period begins on the one hand,

Determine according to the time interval on the other hand.

After the initial injection of dyestuff and chemical composition is finished, in the stage 725, analytical equipment will be determined:

The reference point of the curve of the value that will reach (Fig. 3, reference point 315), and

" first strike " rate (we gallice are expressed as " cold dyeing ").

The reference point of curve is the point of contact of transparency curve when initial injection of dyestuff and chemical composition that changes according to the time.(referring to Fig. 3).

Initially on the transparency that " first strike " rate equals reference point representative and the curve inject the poor of point value when finishing, and the ratio of the difference of the transparency represented of clear water (" Bai Chi ") transparency and reference point.Therefore, if the initial transparency of injecting when finishing equals the transparency of reference point representative, then " first strike " rate is zero.

Therefore, the transparence value when we will inject beginning to dyestuff carries out linear interpolation, determines that dyestuff injects the transparency reference point when finishing, and then determines " first strike " rate.

If " first strike " rate is greater than preset value, as 40%, then we will provide an alarm signal to the user, such as on a user interface, showing an information, thereby make operating personnel can recognize the danger of fabric uneven dyeing, consideration stops the dyeing process, emptying is dyed the pond and treated that the dyeing and weaving thing also begins dyeing cycle again on other base cloth.

According to replacement scheme, we can carry out mathematical combination with the result, thereby determine a whole result, and perhaps we can get a maximum.

In the stage 730, for each spectral region, we carry out a transparency measuring period respectively in the diverse location of piston and different measuring intervals of TIME.We compare difference and the preset value between the given value of measured value and default nominal curve.If the difference between rated value and the measured value is less than preset value, we just enter the stage 740 so.Otherwise in the stage 735, we will control:

A temperature servomechanism installation 562 that dyes the pond,

A servomechanism installation 564 that dyes pond clear water inlet,

One to dying the servomechanism installation 566 that dyestuff is added in the pond, and/or

One to dying the servomechanism installation 568 that chemical addition agent is added in the pond,

So that recover the progressive of dyeing course, thereby make transparence value near default nominal curve, according to known automaton, we get back to the stage 730.

As a kind of replacement scheme, we do not use nominal curve, but when the transparency derivative trends towards zero, according to the transparency that records, regulate.Therefore, we use a specified program.

In the stage 740, we will determine (such as 15 seconds) transparency change value in a Preset Time.Then, in the stage 745, we compare this changing value and a preset value.This preset value can be the function of a reference point and clear water (" Bai Chi ") calibration value.And, if changing value greater than preset value, we return the stage 730 so.Otherwise, can think that dyeing course finishes, we just send a signal to the user, as the passage on the user interface, point out that dyeing course finishes.In the stage 750, the user begins fabric is washed, and the pond is dyed in emptying, and injects clear water.As a kind of replacement scheme, we are in stages 750 beginning flushing automatically.

In the stage 755, for each emission spectrum scope, we have carried out a transparency measuring period, and the difference between measured value and the flushing rated value is compared.This difference and clear water (" the Bai Chi ") transparency that records in the stage 711 to 717, and the transparency and/or the default flushing nominal curve that wash when beginning are relevant.Such as, the flushing rated value equals the transparency that records in the stage 711 to 717.If the difference between rated value and the measured value is less than preset value, we just enter the stage 760 so.

In the stage 760, we will determine (such as 15 seconds) transparency change value in a Preset Time.Then, in the stage 765, we compare this changing value and a preset value.This preset value and clear water (" the Bai Chi ") transparency that records in the stage 711 to 717, and the transparency and/or the default flushing nominal curve that wash when beginning are relevant.And, if changing value greater than preset value, we just return the stage 755 so.Otherwise, can think that dyeing course finishes, we just send a signal to the user, as the passage on the user interface, point out that dyeing course finishes.In the stage 770, the user begins to stop fabric being washed.As a kind of replacement scheme, we stop flushing automatically in the stage 770.

Stage 750 to 770 described above is applicable to overflows flushing.

As a kind of replacement scheme, be applicable to periodically flushing, in the stage 775 after the stage 745, we begin first flushing cycle: the emptying dyeing machine, and fill with clear water.

In the stage 780, when dyeing machine was filled with clear water, for the spectral region of each consideration, we carried out the measurement of one-period.Do not have the spectral region (referring to the stage 230) of eliminating for each, the difference of a value that we will record and a flushing rated value compares.This flushing rated value and clear water (" the Bai Chi ") transparency that records in the stage 715, and the transparency and/or the default flushing nominal curve that wash when beginning are relevant.Such as, the flushing rated value equals the transparence value that records in the stage 715.If after Preset Time finished, the difference of rated value and measured value was less than preset value, we just enter the stage 785.Otherwise we are with regard to duplication stages 775.

In the stage 785, we will determine (such as one-period) transparency change value in a Preset Time.Then, in the stage 790, we compare this changing value and a preset value.This preset value and clear water (" the Bai Chi ") transparency that records in the stage 715, and the transparency and/or the default flushing nominal curve that wash when beginning are relevant.If changing value is greater than preset value, we are with regard to duplication stages 775 so.Otherwise, can think that dyeing course finishes, we just send a signal to the user, as the passage on the user interface, point out that dyeing course finishes.In the stage 795, the user begins to stop fabric being washed.As a kind of replacement scheme, we stop to wash in the stage 795 automatically, dwelling period injection clear water and stopping to be dyed cloth or the motion of fiber, and the emptying dyeing machine.

As a kind of replacement scheme, we can omit the some stages in stage 780 or 790.The changing value of determining when stage 790 is less than stage 790 (omission stage 780) during preset value, thinks that flushing finishes; Perhaps the changing value of determining when stage 780 is less than stage 780 (omission stage 790) during preset value, thinks that flushing finishes.

In stage 711 to 717 and stage 730, piston mediates, or water sample is static condition.

Therefore, piston can be in three positions at least, and these three positions are respectively:

The water channel open to clear water supercharging circulation,

Dye water channel relevant in the pond with liquid circulation, and

Water channel to the sensor sealing.

Therefore, in the implementation shown in Fig. 5 to 7, separate and leave standstill with dying the pond, will no longer the be contaminted interference of bubble and foam in the pond of the measurement of transparency by making above-mentioned water sample.Therefore, when this water sample with dye the pond when separating, the transparency sensor of water sample can provide the representation signal of the above-mentioned water sample transparency at least one spectral region.

In fact, in case water sample after dye the pond and separate and leave standstill, the bubble that may exist in the water sample will be gradually and fluid separation applications, like this, sensor just can record the actual transparency degree of liquid.

The residing position of when sampling piston and water sample with dye the pond when separating between the residing position of piston, this device preferably assembles an anti-foam filter screen.

As our finding, the pond tracking means that dyes of Fig. 5 to Fig. 7 introduction comprises:

One measurements is from the measuring chamber that dyes liquid transparency in the pond.A light source is arranged in the measuring chamber, can send the multi-beam of different bands continuously.

A photoelectric sensor can receive the light that is sent, passed through measuring chamber by light source.This sensor can send a representation signal of the light quantity that receives, and

The lock detector of a band light source is used for the output signal of continuous processes sensor.This wave detector can provide the result on the different bands that sent continuously by Different Light.

Thus, only need a sensor just to handle to being used for measuring the different bands that dye the pond transparency and dye the pond discharging or the process of flushing.

A kind of replacement scheme that has constituted each implementation arbitrarily of the different implementations of the invention described above.Such as, can replace an optical fiber with a fibre bundle, can get rid of the described gearshift of Fig. 1 to Fig. 4, perhaps, on the contrary, can to implementation shown in Figure 7, add this gearshift at Fig. 5.
