Description
Technical field
The present invention relates to a kind of method that yarn is monitored at the work station of weaving loom, the yarn produced in it is given birth at it
By yarn qualities Sensor monitoring between terms, yarn faults are detected, the quality of yarn is assessed and transfers data to control device,
Control device makes the decision on subsequent process at work station.
The invention further relates to a kind of weaving loom for the equipment for having and being used at work station monitor yarn, the weaving loom includes
Row's work station disposed adjacent one another, wherein each work station includes yarn qualities sensor, yarn qualities sensor and yarn
Line operating path is aligned and coupled to control device, and the control device is provided with the dress for making decision and controlling work station
Put.
Background technology
In yarn production, the yarn of production is at the work station of weaving loom by yarn qualities Sensor monitoring, yarn matter
Quantity sensor is connected to work station and/or work station group（Part）And/or machine control device.Yarn qualities sense
Device is mainly autonomous device, is preset to the yarn property of monitoring certain desired, so as to the yarn qualities Sensor monitoring yarn, is commented
Estimate the characteristic of yarn, and the data on result are sent to control device.Then, control device is provided with device, the device
The decision for the step of then being carried out in the case of for making on finding yarn faults at work station.Generally, yarn faults
Detected by yarn qualities sensor, the yarn qualities sensor has set so-called cleaning limitation or so-called cleaning curve.Clearly
It is considered as defect and that clean limitation or cleaning curve characterize those yarn parameters changes detected for yarn qualities sensor
A little differences being not qualified as between defect.The defects of different type, is according to their characteristic, particularly different length and diameter
The defects of or section defect, the uneven or crinosity of yarn（hairiness）Increase etc. distinguished.If yarn parameter
Change exceedes the limit for being limited by cleaning or being cleaned curve limit, then is evaluated as real yarn faults, and yarn lacks
Removal process is fallen into be initiated by control device.
However, in yarn production, when due to a certain yarn parameter be considered defect in one case and
Defect may be not qualified as in the case of difference, and is difficult when finding out whether currently detected yarn parameter is defective, to deposit
In specific activity and situation.
Such typical case is the production of flame, and the parameter of spun yarn is timely at work station during this period
Intentionally change, i.e., along the length of yarn, so that these changes will cause the desired change of yarn parameter.Yarn it is so-called
" fancy quality " manifests themselves as the intentional uneven of yarn appearance（Such as local thick point, local thin point, the part of yarn twisting count
Change etc.）, this have impact on yarn appearance etc..The generation of these " events " in yarn is detected by yarn qualities sensor.However,
In the case of these flames, it is also desirable to detect the generation of undesirable phenomenon, these phenomenons are then evaluated as yarn
The defects of line or the quality of reduction, are hereinafter represented by general terms yarn defect.In general, these yarn defects are detecting it
Afterwards, it is necessary to be removed from yarn.In the case of flame, due to its property, the intentional scrambling of yarn is possibly even
Exceed the border that above-mentioned cleaning limits or cleans curve in a manner of with undesirable scrambling identical, it means that in standard
The scrambling for the yarn that even these are desired in method, are intentionally formed will be classified as actual yarn defect or drop low-quality yarn
Line, and will be off-loaded automatically from yarn and remove（According to its seriousness）, this is undesirable in this case.According to WO
2010009565, it is known that for the solution for the detection for improving fancy yarn yarns defect, wherein in addition to cleaning curve, will also
So-called permission event（The scrambling of permission）Additional areas be incorporated into the evaluation process of yarn defect, its exceed by cleaning limit
The border of system or cleaning curve setting, but sensor or control system are not considered as that they are the defects for the treatment of to remove from yarn.
These allow the region description of the event uneven permission situation of yarn（The defects of permission）Feature, the permission situation examining
Defect is not expressed as when looking into, and does not initiate the process of defect removal.
In addition, US 7,424,800 discloses solution, the solution introduces description in the evaluation process of yarn defect
" excellent " yarn and the additional standard for also describing the intentional scrambling of yarn.When detecting these marks by yarn qualities sensor
During the generation of standard, then determine " excellent " yarn or whether sensed by the yarn qualities with yarn uneven intentionally
Device, or it is undesirable（Do not allow）Whether scrambling is correspondingly made whether start defect remove by sensor
The decision of process.
The shortcomings that these solutions is, it is necessary to change setting and the parameter in the region of permission event, or whenever depositing
The yarn types of production change or yarn parameter intentional scrambling change when additional standard setting, this is
Harsh and complicated process.
Another problem in yarn production is perhaps multi-mode generation, its influence the yarn parameter that detects and although
More than cleaning limitation or cleaning curve, defect can not be construed as, because the state in discussion in terms of whole work station
It is classified as the change of the state deliberately selected or state.One example is typically the spinning phase in certain form of staple fibre
Between yarn adding liquid additive into sir jet spinning machines.The liquid provided is the necessity of technology, and is given birth in yarn
During production and its quality testing, the liquid shows in the yarn in itself, such as by reducing " crinosity " of yarn, is examined by changing
Yarn diameter measured etc..However, if liquid supply defect occurs in this process, no matter reduce or increase what is supplied
Amount of liquid, or in the case of complete defect, this always may not suitably be detected by yarn qualities sensor, and this may lead
Cause subsequent decision mistake etc..In addition, when the intentional change of the amount of the liquid of injection and the yarn parameter as caused by the change
When change may not be classified as defect, it may occur however that situation.
Another problem condition that current yarn qualities sensor fails to sufficiently respond to is the speed of the yarn of such as production
Degree change, it not necessarily reflects the change of yarn thickness or other specification, but its assessment to yarn defect（Particularly must also
The length of defect is evaluated）With significantly affecting.Assuming that the standard speed of yarn movement is 300 in production process
M.min-1, then yarn qualities sensor, which has, cleans limitation or cleaning curve setting with corresponding with this speed, it means that at this
Under the speed of yarn movement, it is determined that length of yarn time per unit by the monitored area of Yarn senser, this is by advance in advance
Hope, because current yarn qualities sensor monitors discontinuously but one after the other yarn, it means that time per unit shoot to
The yarn image of fixed number amount, and this it is determined that defect length and the general evaluation system of yarn qualities assess in be expected to.However, such as
The yarn speed at work station changes fruit for some reason, although the yarn then shot within the unit interval by Yarn senser
The frequency of line image will be identical, but time per unit will will also be changed by the length of yarn of yarn qualities sensor.
However, in the case where not knowing that yarn speed has changed, the length parameter of yarn defect is assessed to yarn qualities sensor error.Cause
This, the assessment of length defect is full of prunes, and the general evaluation system that yarn qualities are assessed is wrong.
When the situation that yarn qualities sensor can not be at the work station to weaving loom is suitably made a response and lacked
The defective detection for the state of falling into, or it is opposite when being not detected by defect state, many other situations also be present.
Therefore, the common drawback of background technology is yarn qualities sensor to condition during yarn is produced at work station
Difference change flexible responses it is limited in one's ability.
It is therefore an object of the present invention to the shortcomings that eliminating or at least minimizing background technology, in particular according in machine
The change of working condition at work station improves the detection of yarn.
The content of the invention
By realizing the purpose of the present invention, the original of this method for monitoring the method for yarn at the work station of weaving loom
Reason is that control device will be online on the information of the current operational conditions of work station and be transferred to yarn qualities sensing in real time
Device, so as to which correspondingly adjustment monitors yarn and assesses the process of yarn parameter, and adjusted monitoring yarn qualities process
Result be sent to control device, so as to make the decision on the subsequent process at work station.
The invention further relates to the weaving loom with the equipment for monitoring yarn at work station, the principle of the weaving loom exists
Interconnected in yarn qualities sensor and control device by device, the device is used for the transmission of online and real time bidirectional on life
The parameter of the yarn of production and/or the information on the condition change at work station.
The advantages of solution, is that it can be according to the operation currently performed at work station, in real-time mode
Operationally change the setting of yarn qualities sensor, suitably to set yarn qualities sensor all the time, with according to work
The current setting for the operating mechanism stood monitors the yarn of production.

According to another advantageous embodiment, control device 8 is transmitted in the length of yarn 3 to yarn qualities sensor 9
Various pieces in yarn 3 intentional uneven at least one qualitative parameter information.Therefore, yarn qualities sensor 9 can
With the angle of the parameter from yarn 3 in the given part of yarn 3 come assess yarn 3 it is each intentionally it is uneven.
In another embodiment of the present invention, when monitoring the quality of uniform yarn 3 on Air-Jet Spinning loom, wherein
Auxiliary liquid（Usually water or water base mixture or other liquid）Fed during yarn 3 is formed, in the yarn of standard
The fact that the production period of line 3, yarn 3 show some parameters, including it includes the liquid.According to the yarn 3 detected
Parameter, this for example influences the crinosity of yarn 3.However, if the crinosity of the yarn 3 detected changes, this is not necessarily mean that
Liquid supplies mistake, because it can also be caused by other mistakes.Because the present invention is fully automated, therefore can be made as to whether
The determination of liquid supply mistake be present.For example, control system 8 gives signal to liquid delivery system（Increase liquid supply
Signal）, the liquid delivery system is also one in other working nodes 7 at work station.Meanwhile control system 8 is to yarn
Mass sensor 9 is online and sends the information on liquid supply change in real time, and yarn qualities sensor 9 is larger
Yarn 3 is monitored in the case of the liquid of amount to be ready, and will detection in the case of no liquid or with a small amount of liquid
To the parameter of yarn 3 be sent to control device 8.According to the parameter of yarn 3 detected, control device 8 and then decision work station
The further step at place, such as be stopped station and removal defect, or recover the original supply of liquid and recover spinning, or
Another test is determined, wherein the supply of the liquid for example fed is stopped or reduced, information is online and is sent in real time
Yarn qualities sensor, the yarn qualities sensor are to monitor this yarn 3 to be ready and send out the parameter of yarn 3 detected
Send back to control device 8.Then, control device 8 determines the further process operated at work station.
Another example using the present invention is the repetition of the speed of yarn 3 in stable yarn 3 produces（It is short
Phase）During change, when control device 8 by the speed of yarn 3 this repetition（In short term）The information of change is online and in real time
When being sent to yarn qualities sensor 9, the defects of yarn 3 can also be correctly detected and oeverall quality, yarn qualities sensor 9
The setting of its parameter is adjusted in real time to adapt it to the present speed of yarn 3, and then according to the present speed of the motion of yarn 3
Adaptively perform the appropriate and reliable monitoring to the mass of yarn 3（Transmit data to control device 8）.
Therefore, essential characteristic of the invention is yarn qualities sensor to the conditions present at work station or to these conditions
The adaptation changed immediately, this is online by control device 8 and current at the work station of notice yarn qualities sensor 9 in real time
The change of condition or these conditions and become possible to.Therefore, yarn qualities sensor 9 is adapted to these conditions presents all the time, and
And the generation of the quality and defect of yarn 3 can be correctly assessed in all cases, or for detecting the work of work station
State of device etc..
In principle, the present invention is always based on the conditions present at work station or based on the working node 1 to 7 at work station
Current setting, it is allowed to the parameter of yarn 3 carry out adaptability sensing.
It is obvious that in the presence of many possible plots for the yarn qualities sensor for how using adaptability, but protect all the time
Hold general principle, i.e., control device 8 will be online on the information of the current operational conditions of work station and be transferred to yarn in real time
Mass sensor 9, yarn qualities sensor 9 correspondingly adjust the process and the parameter evaluation of yarn 3 of the monitoring of yarn 3, and will be by
The result of this adjusted quality-monitoring of yarn 3 is sent to control device 8, and control device 8 determines the subsequent mistake at work station
Journey.Control device 8 transmits the beginning and end of the operation change of the node 1 to 7 on work station to yarn qualities sensor 9,
Or start and the information of duration, or control device 8 transmitted in each portion of yarn 3 to yarn qualities sensor 9
The information of at least one qualitative parameter of the operation change of the node 1 to 7 of work station in point.Based on the node 1 on work station
