Description
Technical field
The present invention relates to a kind of particularly method that has situation (finishing agent method for supervising) of oil of finishing agent that is used to monitor; The method is on a coating unit; Carry out in the time of on the textile yarn in certain finishing agent coating amount being coated to the weaving silk thread in advancing by means of this coating unit or advancing, the invention still further relates to a kind of equipment that is used to implement this method.Said finishing agent exist situation especially also refer to finishing agent that is finishing agent stream flowing velocity have a situation.Said finishing agent method for supervising has following method step:
-by means of dosing system, from a reservoir vessel, carry the finishing agent coating amount towards the coating unit direction through fluid pipeline, be used for controllably carrying finishing agent to be applied,
-first measurement point on fluid pipeline is by means of one of first temperature sensor measurement, first finishing agent temperature curve over time,
-second measurement point on fluid pipeline is by means of one of second temperature sensor measurement, second finishing agent temperature curve over time,
-will be to be carried between said first and second measurement points by means of heating arrangement finishing agent heating, and
-confirm the curve over time of the difference of measured finishing agent temperature, and the curve over time of the difference through assessing measured finishing agent temperature is monitored the situation that exists of finishing agent.
Background technology
Textile assistant for example emulsion and the mineral oil of plant is called as finishing agent, and they for example improve its performance and/or characteristic when the silk thread following process.Silk thread is called as arrangement through the processing that finishing agent carries out.For example in EP 1 405 938 A1, disclose such equipment (collator), be used for certain finishing agent coating amount is coated to silk thread.Wherein, the control unit of dosing system is connected on the sensor, and this sensor is used for surveying the yarn speed of the silk thread of advancing to be put in order, and according to calculating the finishing agent coating amount by means of the measured yarn speed of sensor.In such collator, must guarantee during operation: untreated zone on silk thread to be put in order, do not occur, that is on the coating unit direction, must have enough finishing agents lastingly.For this reason, the curve over time of the difference through confirming measured finishing agent temperature, the curve over time of the difference through assessing measured finishing agent temperature is implemented the monitoring that has situation of finishing agent.
Particularly when beginning to apply this finishing agent coating amount; For example during carrying out the winder of yarn bobbin by bobbin-winding machine; Be lower than under the very little finishing agent coating amount situation of 0.5 grams per minute (g/min); When the curve over time of poor (that is the induced signal of temperature sensor is poor) of assessing measured finishing agent temperature, may encounter difficulties, therefore, on the coating unit direction, can not confirm the situation that exists of finishing agent definitely reliably.
The induced signal difference is directly proportional with the delivery speed of finishing agent coating amount through fluid pipeline.Delivery speed is high more, and heated finishing agent is just fast more to the conveying of the second temperature sensor direction in heating region.
Heating arrangement is positioned near first temperature sensor, than nearer from second temperature sensor.In quiescence, that is when not having finishing agent stream, owing to be static state between temperature sensor, so ratio is heated at the second temperature sensor place finishing agent more consumingly at the first temperature sensor place.When finishing agent is transferred, promptly there is finishing agent stream, then, makes heat be sent to second temperature sensor from heating arrangement through this finishing agent stream.Thereby ratio produces higher temperature at the first temperature sensor place at the second temperature sensor place.
Finishing agent stream is big more; Described effect is by disturbing factor, particularly disturbed fewly more by diffusion process (temperature drift), and can confirm the situation that exists of finishing agent further reliably by means of the curve over time of the difference of the measured finishing agent temperature of assessment.Difficulty in assessment produces thus; Promptly; In order when beginning to apply this finishing agent coating amount, to confirm the situation that exists of finishing agent; That is for example at the starting bobbin-winding machine when (using the finishing agent method for supervising above that), the edge (pulse) that one of analysis and evaluation occurs in the conditional curve of induced signal difference owing to begin to carry finishing agent, promptly one of the induced signal difference over time.Very little and when causing delivery speed very little thus, temperature drift maybe be so big when the finishing agent coating amount, thus the induced signal difference does not have the significant edge (pulse) that has situation that is enough to reliably confirm finishing agent.
Summary of the invention
The objective of the invention is, a kind of method that has situation that is used to monitor finishing agent is provided, this method has been avoided the shortcoming of prior art, wherein, particularly when little operational throughput, also can monitor the situation that exists of finishing agent reliably.
For this reason; The present invention provides a kind of method that has situation that is used to monitor finishing agent; The method is on a coating unit; Carry out in the time of on the textile yarn in certain finishing agent coating amount being coated to the weaving silk thread in advancing by means of this coating unit or advancing, comprise following method step:, carry the finishing agent coating amount towards the coating unit direction through fluid pipeline by means of dosing system; Be used for controllably carrying finishing agent to be applied; First measurement point on fluid pipeline is by means of one of first temperature sensor measurement, first finishing agent temperature curve over time, and second measurement point on fluid pipeline is by means of one of second temperature sensor measurement, second finishing agent temperature curve over time, finishing agent heating that will be to be carried by means of heating arrangement between said first and second measurement points; And the curve over time of confirming the difference of measured finishing agent temperature; And the curve over time of the difference through assessing measured finishing agent temperature monitors the situation that exists of finishing agent, it is characterized in that, during measuring the finishing agent temperature; In a time gap, produce an of short duration finishing agent operational throughput that departs from the finishing agent coating amount by means of dosing system and change.
Correspondingly, the present invention provide a kind of by means of a coating unit with certain finishing agent coating amount be coated in advancing the weaving silk thread or advance in textile yarn on equipment, it comprises: the dosing system that comprises a control unit; Be used for carrying finishing agent to be applied towards coating unit through fluid pipeline directionally controlledly; The finishing agent measuring system comprises that one is used for measuring one of the first finishing agent temperature in first measurement point on the fluid pipeline first temperature sensor and one of curve are used on fluid pipeline second measurement point and measure one of the second finishing agent temperature second temperature sensor of curve over time over time; Wherein, Be provided with one and be used for, and the analysis and assessment unit, be used for confirming the curve over time of the difference of measured finishing agent temperature at the heating arrangement of heating finishing agent to be carried between first and second measurement points on the fluid pipeline; Monitor the situation that exists of finishing agent with the curve over time that is used for the difference through assessing measured finishing agent temperature; It is characterized in that, said control unit is set, control dosing system by following mode; Promptly; During measuring the finishing agent temperature, in a time gap, produce an of short duration finishing agent operational throughput that departs from the finishing agent coating amount by means of said dosing system and change.
In according to method of the present invention; Can monitor finishing agent particularly oil have a situation; The method is for example to be designed on the coater nozzle coating unit at one; Carry out in the time of on the textile yarn in by means of this coating unit certain finishing agent coating amount being coated to the weaving silk thread in advancing or advancing, particularly at the finishing agent coating amount less than 0.5 grams per minute, preferably under the situation less than 0.3 or 0.2 grams per minute.Have following method step according to method of the present invention:
-by means of dosing system, particularly from a reservoir vessel, carry the finishing agent coating amount towards the coating unit direction through fluid pipeline, be used for controllably carrying finishing agent to be applied.At this, the finishing agent coating amount can change in the process that applies, for example described in EP 1 405 938 A1.Wherein, the finishing agent coating amount can be confirmed by three kinds of modes especially.The one,, can the for example known yarn speed of a certain bobbin position control be forwarded to the finishing agent control of dosing system.Be to survey the wheel measurement yarn speed by means of one, and forward it finishing agent control of dosing system in addition.Besides, for example yarn speed is imported in the artificially in the finishing agent control of dosing system.Like this, the control of dosing system just realizes through a kind of beginning-stop-signal.
-first measurement point on fluid pipeline is by means of the curve over time of one first temperature sensor measurement, the first finishing agent temperature, and second measurement point on fluid pipeline is by means of the curve over time of one second temperature sensor measurement, the second finishing agent temperature.At this, needn't measure the temperature of finishing agent itself.For example, the surface temperature of measurement fluid pipeline is just enough on measurement point.
-between first and second measurement points; Heat finishing agent to be carried by means of a heating device; And confirm the curve over time (heal differential) of the difference of measured finishing agent temperature, and the curve over time of the difference through assessing measured finishing agent temperature is monitored the situation that exists of finishing agent.
According to the present invention; During measuring the finishing agent temperature; In a time gap, produce an of short duration finishing agent operational throughput that departs from the finishing agent coating amount by means of dosing system and change (increasing (Boost)), that is the finishing agent operational throughput raises and/or reduction.
By means of method of the present invention; Under through the very little situation of the finishing agent flow velocity of fluid pipeline; Until the quiescence that finishing agent is carried; That is, also can produce a curve over time that is enough to discern the difference that has finishing agent temperature situation, measured of finishing agent when finishing agent coating amount seldom the time.According to prior art, the difference of measured finishing agent temperature is just very little, particularly because temperature drift; It no longer can be different from interfering signal sometimes; And by means of according to method of the present invention, it is big that the difference of finishing agent temperature is able to become, and therefore can carry out analysis and assessment to it more reliably.This realizes through following manner,, because of short duration finishing agent coating amount changes, and in the induced signal difference, produces the edge (pulse) of a rising that is, and when finishing agent coating amount seldom the time, this edge is enough to discern reliably the situation that exists of finishing agent.In order to define a kind of increase (Boost); Curve over time for the variation of finishing agent operational throughput; Can preferably be suitable for: curve has a steep rising and a steep decline over time; That is to say that rising and the time length that descends are merely per centum that total finishing agent operational throughput changes time length, for example are less than 10%.For the finishing agent coating amount, this increases and causes a heal differential stronger with respect to the finishing agent operational throughput (sensor response).This stronger sensor response is by analysis and assessment.
If the time gap that the finishing agent operational throughput changes be less than 10 seconds, preferably up to one section time length of 3 seconds, it is poor then to produce an induced signal that has situation that is enough in known finishing agent equipment, to be used to monitor finishing agent.At this, the operational throughput that the finishing agent operational throughput changes is 1 to 100 microlitre, and this interference that can not cause finishing agent on silk thread or yarn, to apply changes.
Preferably during continuous, a unbroken coating process; After the finishing agent operational throughput of a finishing agent coating amount temporary transient, that surpass the expectation raises; In fluid pipeline,, carry out the of short duration loopback of certain finishing agent loopback amount by means of dosing system against the coating unit direction.This loopback can for example directly be carried out after the finishing agent operational throughput raises.Therefore also can, relatively large, of short duration finishing agent operational throughput avoid occurring in undesirable variation that finishing agent applies on silk thread or the yarn when changing.
Finishing agent loopback amount advantageously raises corresponding to the finishing agent operational throughput, wherein, the time length of preferred loopback corresponding to the finishing agent operational throughput raise, the time length when beginning to apply for example.By this way, finishing agent loopback amount can keep constant in the time stage casing.
Particularly advantageously be; Carrying out the finishing agent operational throughput in the textile yarn in the finishing agent coating amount begins to be coated in the weaving silk thread in advancing or advances raises; That is when spindle begins starting and is wound into silk thread or yarn on it; And loopback is to carry out in the finishing agent coating amount finish applying, that is when spindle stops to be wound into silk thread or yarn on it perhaps after this.Back one method flexible program is suitable for such application especially, that is, and and the yarn that will be to be put in order after loopback or the drum-changing of silk thread.Because it is the same big with negative increase when finishing in the increase in when beginning; That is when stopping to apply finishing agent; Do not rely on the enforcement that changes according to finishing agent operational throughput of the present invention, particularly when the finishing agent volume that increases was consistent, the finishing agent coating amount on silk thread or the yarn remained unchanged.In fluid pipeline, only there is a small amount of finishing agent to carry forward and backward.When spindle stops, perhaps after this, compensate additional finishing agent operational throughput, therefore, on silk thread or yarn, always cause applying accurately, that is have desired finishing agent coating amount through said being increased in when beginning.When beginning for the first time, that is when yarn processing machine (it is provided with and is used to implement the equipment according to the inventive method) started, finishing agent must be introduced in the system, that is to say, in fluid pipeline, carried finishing agent through it.Therefore when starting, the finishing agent operational throughput of expection can not disturbed by increasing for the first time.
A kind of in order to implement to have set up according to equipment of the present invention according to method of the present invention, be used for by means of a coating unit particularly coater nozzle certain finishing agent coating amount is coated to the weaving silk thread of advancing or advance in textile yarn.Have according to the equipment that is used to apply certain finishing agent coating amount of the present invention:
-comprise the dosing system of a control unit, be used for particularly carrying finishing agent to be applied through fluid pipeline towards coating unit from a reservoir vessel directionally controlledly,
-finishing agent measuring system; Comprise that one is used on fluid pipeline first measurement point and measures one of the first finishing agent temperature first temperature sensor of curve over time; With one be used on fluid pipeline second measurement point and measure one of the second finishing agent temperature second temperature sensor of curve over time; Wherein, be provided with one and be used at the heating arrangement that heats finishing agent to be carried on the fluid pipeline between first and second measurement points, and
-analysis and assessment unit is used for confirming curve over time and the situation that exists that the curve over time that is used for the difference through assessing measured finishing agent temperature is monitored finishing agent of the difference of measured finishing agent temperature.
Be provided with control unit according to the present invention; In this wise dosing system is controlled, that is, and during measuring the finishing agent temperature; In a time gap, produce an of short duration finishing agent operational throughput that departs from the finishing agent coating amount by means of dosing system and change.Therefore produce the variation between temperature sensor of the curve over time of a difference that has situation that is finishing agent temperature that be enough to assess, measured that is enough to confirm finishing agent; That is to say; Therefore, the curve over time of the difference of measured finishing agent temperature has an enough significant edge (pulse) that is used for analysis and assessment.
When control unit is set, in this wise dosing system is controlled, promptly; After of short duration finishing agent operational throughput raises; In fluid pipeline, carry out the of short duration loopback of certain finishing agent loopback amount, particularly after a winder process that applies finishing agent has stopped, at this against the coating unit direction; By means of dosing system; The finishing agent coating amount that is applied on silk thread or the yarn can keep constant, particularly, equals finishing agent loopback amount if the finishing agent operational throughput raises.
Dosing system preferably has one can realize the accuracy control to the finishing agent operational throughput with simple mode thus by the pump that promotes magnet drives, because such lifting magnet can carry out the pulsating suction to finishing agent through fluid pipeline.But dosing system can have drive system arbitrarily in principle, particularly arbitrarily electrical motor as actuating device.
Heating arrangement preferably is positioned between first and second temperature sensors asymmetricly, finally causes induced signal difference highly significant.Because, confirm the heal differential between first and second temperature sensors for the situation that exists of analysis and assessment finishing agent, therefore, be imported into the heat energy in the finishing agent, that is heating power, can between temperature sensor, keep very for a short time.In quiescence, because be static between temperature sensor, ratio is heated at the second temperature sensor place finishing agent more consumingly at the first temperature sensor place.Be transferred like finishing agent, then heat is sent to second temperature sensor through finishing agent stream from heating arrangement.Obtained higher temperature than the first temperature sensor place at the second temperature sensor place.
Be specially adapted to particularly apply finishing agent in the bobbin-winding machine according to equipment of the present invention at yarn processing machine.At this, for the finishing agent that liquefies, a heating arrangement can be set, it is positioned at after the equipment, preferably directly before finishing agent being coated on silk thread or the yarn, so that improve the flow characteristic of finishing agent.
Description of drawings
Below by means of an embodiment with reference to the present invention of accompanying drawing illustrated in detail.In the accompanying drawing:
Fig. 1 is according to the scheme drawing of collator of the present invention;
The curve over time of Fig. 2 difference of measured finishing agent temperature in and corresponding finishing agent operational throughput curve according to collator of the present invention.
The specific embodiment
Accompanying drawing simply illustrates scheme theme of the present invention, is that not to scale (NTS) is represented.Each assembly of the present invention program's theme illustrates by this way,, can express its structure well that is.
Shown in Fig. 1 according to a scheme drawing of collator of the present invention (equipment oils).Yarn 2 to be put in order from a feeding bobbin 3 unwindings, and is wound on the package bobbin 4 in a bobbin position.At this, the coating unit 6 that is configured to coater nozzle in the zone by means of a spinning line that is positioned in yarn 2 is coated in certain finishing agent coating amount on the yarn 2 in advancing.Finishing agent to be applied is that the finishing agent coating amount is transported in the coater nozzle equipment through a fluid pipeline 8.Finishing agent by means of dosing system 11 usefulness of a Be Controlled unit 10 control for example one can carry by the pump of stepper motor driving.The conveying of finishing agent coating amount is to represent through the line that is provided with arrow in fluid pipeline 8 inside.
Finishing agent measuring system in location on fluid pipeline 8; It comprises that curve and one second temperature sensor 14 are used for measuring one of second finishing agent temperature curve over time with second measurement point on fluid pipeline 8 one first temperature sensor 13 over time in order to measure one of the first finishing agent temperature in first measurement point on the fluid pipeline 8.By means of a heating arrangement 16, heating finishing agent to be carried on the fluid pipeline 8 between first and second measurement points.At this, heating arrangement 16 is to locate with respect to measurement point asymmetricly, that is, for example, the distance between the heating arrangement 16 and first measurement point is less than the distance between the heating arrangement 16 and second measurement point.
Measured finishing agent temperature for example passes to an analysis and assessment unit as the induced signal of temperature sensor 13,14.The curve over time of the poor Δ T of measured finishing agent temperature confirmed by this analysis and assessment unit, and the curve over time that is used for the difference through assessing measured finishing agent temperature is monitored the situation that exists of finishing agent.The analysis and assessment unit can for example be configured to microcomputer or micro chip, on its simulation inlet, applies the induced signal of temperature sensor.Also can adopt an independently unit; Differential amplifier 20 for example; As the parts of analysis and assessment unit, in order to confirm the poor of measured finishing agent temperature, like this; Difference just can be used as this independently i.e. poor as induced signal of output of unit, carries out analysis and assessment as the input of a simulation inlet of microcomputer 21.
In the example shown, microcomputer 21 is used as the control unit 10 of dosing system 11 simultaneously.This control unit 10 is control dosing system 11 like this; Promptly; During measuring the finishing agent temperature, in a time gap, surpass the finishing agent operational throughput finishing agent coating amount, of short duration, that rising realizes as the finishing agent operational throughput by means of one of dosing system 11 generation and change 25.The of short duration rising that the latter can for example pass through the pump motor rotating speed realizes.This of short duration finishing agent operational throughput rising 25 raises as rectangle in the accompanying drawings and is depicted on the line of the conveying of representing the finishing agent coating amount with arrow.
Fig. 2 is illustrated in the corresponding finishing agent operational throughput curve 35, measured finishing agent temperature poor-as the curve over time of poor (induced signal is poor) 30 of the induced signal of temperature sensor.For example, can adopt the motor speed of the pump motor that drives dosing system to represent finishing agent operational throughput curve 35.Shown finishing agent operational throughput curve 35 has finishing agent operational throughput (just increasing) 37 that raise, it be on the textile yarn in the finishing agent coating amount begins to be coated to the weaving silk thread in advancing or advances in, that is when the value of time shaft t is very little.These finishing agent operational throughput rising 37 subregions as finishing agent operational throughput curve 35 illustrate, and this zone surpasses for example steady state value zone of finishing agent coating amount.In shown finishing agent operational throughput curve 35; In end coating finishing agent coating amount; That is when the value of time shaft t is high; Just just increasing after 37, in fluid pipeline, carrying out the of short duration loopback 39 of certain finishing agent loopback amount (negative increase) by means of dosing system against the coating unit direction.This loopback illustrates as the subregion of finishing agent operational throughput curve 35, and this zone is for example under the steady state value zone of finishing agent coating amount.In fluid pipeline, exist the induced signal shown in just drawing under the situation of finishing agent to differ from 30.Because second temperature sensor is set in the zone after the heating arrangement, so, differed from 30 o'clock a kind of like this induced signal occurring exactly, can infer the coating unit aspect finishing agent have a situation.In order to realize that at this moment induced signal is differed from the assessment of necessity of 30, use the induced signal that draws from finishing agent operational throughput curve 35 and differ from 30 40,41 zones, edge (pulse).This edge 40,41 be respectively along with in the accompanying drawings through shown in each double-head arrow, with respect to increasing or just increasing the time delay that the finishing agent operational throughput that produced changes and occur by negative.This time delay flows from finishing agent, but also comprises the time delay that is determined by system, for example carries out the time constant that temperature is transmitted to temperature sensor.At this and since the time delay that causes of finishing agent conductance be equivalent to be used to make finishing agent along from heating arrangement to be positioned at flowing the required time of thereafter temperature sensor at flow direction apart from the highway section.
When beginning to apply, Once you begin start the bobbin position among Fig. 1 for example, then the of short duration rising of the rotating speed of the pump drive through dosing system has just produced and has increased.At this, raise 39 as the finishing agent operational throughput, the amount that can in for example about 2 seconds time, carry for example about 40 microlitres.This is just increasing and has the for example finishing agent volume of several microlitres, and in by the circulation sensor of finishing agent measuring system structure, produces the edge (pulse) of a rising of induced signal difference.If after this increases, induced signal differs from 30 with a definite critical value decline, and then finishing agent exists.After this, the pump time per unit of dosing system is carried a predefined finishing agent coating amount.This moment, induced signal differed from 30 slowly risings.The lower induced signal that is caused by said increase that should slowly rise differs from 30 generations.If get rid of to disturb value of consult volume, after a period of time, induced signal differs from 30 and will be stabilized on the value of characteristic of a predefined finishing agent coating amount that characterizes time per unit.
When end applies, directly after the pump of dosing system is shut down, dosing system Be Controlled unit is controlled like this, that is, pump produces negative increase by 39 through the of short duration loopback of finishing agent.At this, the finishing agent loopback is performed such, that is, said negative increase by 39 at least aspect its finishing agent volume that is pumped, preferred also consistent with just increase by 37 before aspect the curve over time at it, that is by value, equate.Should negative increase the finishing agent volume that comprises several microlitres, its cause induced signal differ from 30 faster with more rise on the highland.If induced signal differs from 30 this negative increasing after 39 with a definite critical value rising, then finishing agent existence.
A kind of method that has situation that is used to monitor finishing agent has been proposed; The method is on a coating unit 6; In in certain finishing agent coating amount being coated to the weaving silk thread in advancing by means of this coating unit 6 or advancing 2 last times of textile yarn, carry out, and comprises following method step:
-by means of dosing system 11, particularly from a reservoir vessel, carry the finishing agent coating amount towards the coating unit direction through fluid pipeline 8, be used for controllably carrying finishing agent to be applied,
-first measurement point on fluid pipeline is measured one of first finishing agent temperature curve over time by means of first temperature sensor 13,
