Description
Technical field
The present invention relates to a kind of spinning machine or spinning preparing machine, have the drawing-off of being used for such as cotton, the fiber of polyester or material like that is in conjunction with the drafting system of strip, has the draw zone that at least one is formed by two identical drafters, have one and pass device, be used for being determined to the drawing-off height of a rare draw zone, at least before drafting system, connect an input sensor and/or behind drafting system, connect an output sensor at least, be used to determine to input or output the weight of end fiber in conjunction with strip section per unit length fiber skein cross section or fiber, and, be respectively applied for the method for setting up amplitude-frequency-function (spectrogram) and/or amplitude-time-function (curve map) at least by the test signal of input and/or output sensor.The present invention relates to a kind of corresponding method equally.
Background technology
The known spinning preparing machine that has drafting system utilizes the sensor of respective design in input and output, can set up the spectrogram of fiber skein, and promptly a kind of amplitude-frequency-function is used to find out periodic flaw, and represents scheme.For example by U.S. Pat 5,509,179 learn, in order to control and regulate drafting process, obtain corresponding signal from the spectrogram of input and output material.Similarly be to learn,, accept a spectrogram respectively at the input and the output of drawing frame equally in order to revise flaw accordingly and to calculate corresponding correction value in the discriminance analysis signal from European patent 574,693.Be known that equally at the machine output and take out one section long drawn fiber strip, and go up test at a laboratory test instrument (a so-called uster tester device uster-Tester).For the last use of mentioning instrument, only determine applicable these information, whether fiber skein satisfies desirable requirement or is not.
Amplitude-time-the function that provides so-called curve map form to be is provided equally, therefrom can finds out the flaw at random of fibrous material, for example slubbing and details.
Shortcoming in known device is, is not best by the information content that spectrogram and curve map provided.Therefore task of the present invention is better at input and/or output sensor with utilize the information of spectrogram that Laboratory Instruments obtains and/or curve map where necessary.
Summary of the invention
Task of the present invention is by the feature of claim independently, the method and apparatus of mentioning when solving beginning.
The appreciable advantage of the present invention particularly is, in order on fiber skein output or drawing-off, to obtain the prompting of fiber skein weight cause of fluctuation, utilize the help of computer (for example microprocessor), finish the input sensor, the spectrogram and/or the curve map of output sensor and/or laboratory test instrument (having two kinds at least in three kinds), corresponding soft program is related mutually.The best deducibility of such evaluation, which position of spinning preparing machine has been caused flaw or can not have been compensated on drafting system.
When the spectrogram of at least two kinds of sensors of mentioning and curve map are done mutually relatively, not necessarily must use all three kinds of equipment according to the present invention, but two kinds of equipment are enough to enforcement of the present invention.
The source of fiber skein flaw can be positioned by computer specially, and the flaw source produces before the input sensor and/or between the input and output end sensor.In order to infer the flaw source, mainly be to be mutual calibration with the spectrogram of input sensor and output sensor and curve map mutual superposition and in necessity according to the flaw of two spectrograms or curve map.
For example at the input sensor, equally also in the spectrogram of output sensor or curve map, can discern flaw, the material flaw that exists in the deducibility drafting system can not be got rid of thus.On the other hand at the output spectrogram or the deviation of standard value in the output curve map, occurred leaving, this does not exist in input spectrogram or input curve map, starting point to this is, promptly between input and output sensor in the drafting system, exist flaw or a kind of other flaw source.
Preferably consistent with each other to the fiber skein that will compare mutually, thus the fiber skein section always compares with identical fiber.This point is for very accurate measurement advantageous particularly.When such accuracy when being unwanted, particularly when when whole fiber skein appears as periodic flaw, uniformity is not absolute demand just.Because when the window through selecting, for example the fiber of Lian Jieing is in conjunction with the information of strip, and occurring periodically, flaw is identical basically.
When flaw exists and when strip flaw or deviation also belong to standard, nature is preferably regulated by the operator according to the corresponding limiting value of definition.
Utilize the present invention also can determine, whether the strip flaw is created in output sensor back.Replace input and output-or additional-two kinds of spectrograms and/or the comparison of curve map, also can use the spectrogram and the curve map of the drawn fiber strip of accepting by the laboratory test instrument, the fiber skein of this drawing-off takes out in the bar tube that is full of usually.Used a uniformity inspection instrument for this purpose, in all conventions, all used the uster tester device, with the laboratory test instrument of briefly speaking of above being used for.Particularly by spectrogram and curve map by the laboratory test instrument, at least compare with the spectrogram and the curve map of output sensor, whether the flaw that can infer strip on the drawing frame occurs between output sensor and the bar tube, for example, enter the bar tube with coil form by the rotating disk belt by producing wrong strap in the rotating disk.
People distinguish two kinds of situations usually when the spectrogram evaluation, on the one hand be between drafting wave or drawing-off are disturbed, and the spectrum line that multiple wide cut rises has appearred simultaneously in these ripples and to disturb be not strictly periodically to repeat in spectrogram; Being mechanical faults on the other hand, is that strict periodicity repeats, and has occurred the spectrum line of one or two rising in spectrogram.The flaw of at first mentioning is the floating fiber that produces in drafting system.It is improper to regulate as drafting system, then drafting wave may occur, causes producing uncontrollable staple fibre and floating fiber.Also may select the strip horn mouth too narrow, perhaps the drafting system Load Regulation is low excessively.The top roller cover plate is improper in addition may be the basis of drafting wave.
May produce strict periodic or mechanical flaw in contrast, this produces by various drive disk assemblies or workpiece, for example owing to clash into cylinder, damaged bearing, the top roller of oval-shaped or passivation, driving belt damaged or that make dirty, drive or gear.
The method according to this invention, at least can relatively easily discern the comparison of two kinds of spectrograms, be periodic flaw of non-strictness and strict periodic flaw, so that not only infer the flaw of flaw in drafting system or behind the drafting system before the drafting system, but also deducibility flaw source and most of flaw place and/or flaw kind.
Analyzing the degree of in drafting system, getting rid of especially, utilizing a kind of cross relation the spectrum comparison method just to occur from computer by the reason and the reason of drawing-off generation slubbing and/or details.The for example sensor by input and slubbing before drafting system, the process certain-length is 50cm for example, and measuring strip thickness flaw is 15%, drops to 10% by drawing-off slubbing flaw, the reason of this flaw can be sought in drafting system, and for example top roller load is wrong.For long slubbing and details, then need better adjusting especially.Can find out simultaneously whether originally in drafting system, produce by drafting process slubbing and details.
Particularly advantageous is according to comparison of the present invention, to scheme the source of expression flaw, can equally get rid of reason to this operator to the operator.Usually just appear on the spinning preparing machine, for example on drawing frame, use display.Preferably give operator's the indication of originating of being not only, and be the suggestion of getting rid of flaw about flaw.These two kinds of information also may take place simultaneously, if show cylinder or rolling bearing in the transmission plane for example on display, the operator just knows that he need check or change bearing.
For can be immediately or make more accurate localization and the final flaw of getting rid of to flaw, when a plurality of possible flaw occurring, be preferably in and give concrete suggestion of operator on the display by the measure (for example progressively test) of system.Flaw for example will find out whether flaw depends on total draft, preliminary draft, feed speed and/or adjusting during the location.Whether also can analyze flaw relevant with the strip storage level and write down a real or fict flaw thus.Belonging to such recommendations mainly is, the change of total draft, at total draft is under the situation of constant, the change of preliminary draft in two continuous drafting districts, the change of dominant draft, the change of one or more drawing-off spacings, the change of drafting system load, the change of top roller cover plate, regulate the change of tap points, the bell-mouthed replacing of drafting system output strip, the change of rotary speed, leave the change of drafting system fiber skein feed speed, the change of draw zone pressure bar position and/or the replacing of defective top roller.Also can point out, comprise whether the carding machine that the adjusting of drawing frame of drafting system and/or drafting system are preposition or the adjusting of combing machine should change to the operator.Carding machine or combing machine can be machines separately herein, and spinning preparing machine perhaps according to the present invention is a kind of integrated machine (unitization design) that comprises drafting system.
The invention viewpoint that reaches activity classification of classification also can be regarded independently, install to a kind of method of suggestion order in the machine as, must not compare two or three spectrograms or curve map to these viewpoints.Spectrogram or the curve map just mentioned according to the suggestion of machine of the present invention are favourable do mechanical analysis, because saved usually the long-time information of seeking publication flaw dictionary in handbook.Would rather give operator-preferably at first is to get rid of flaw by the display-a kind of work plan according to machine of the present invention.Particularly under the situation of multiple possible flaw reason, by electronics storage flaw dictionary and in case of necessity also can be by unique and also by electronics storage empirical value (self-study flaw dictionary), machine can be advised to the operator, those may be the reasons of flaw, and the operator at first must seek the eliminating flaw there for this reason.
Two invention viewpoints that are suitable for are preferably especially that spinning preparing machine arranges, and especially by servomotor or other, the flaw eliminating measure can be carried out automatically.For example, get rid of in order better to reach flaw location or other flaws, the calibration command of this starting computer in order to change total draft and/or preliminary draft automatically.So can seek the flaw part at least and better realize automatic flaw location where necessary.
The flaw of just some areas roughly being determined is followed the trail of continuously at the beginning, preferentially reuse according to evaluation method of the present invention, to two evaluations in the spectrogram (perhaps three all), the for example evaluation of input and output spectrogram, and the spectrogram of where necessary the drawn fiber strip being accepted is to the sensor emergency of laboratory test device.A kind of then optimization action of further eliminating flaw can be implemented.This situation is according to the curve map evaluation.
According to spinning preparing machine of the present invention, it is characterized in that the comparative evaluation of at least two according to the present invention spectrograms of computer work or curve map.This computer can be a central location or independent computer of spinning preparing machine.The software of computer is design like this, and is by the comparison of two spectrograms or curve map, attainable during the local positioning in strip flaw source.
Computer can from the laboratory test instrument of check strip uniformity function for example the uster tester device handle preferred value, operator or process computer input device, or cable, radio and infrared ray or the suchlike method of process laboratory test instrument are transmitted preferred value on computers.Correspondingly computer also can be included in the test value of laboratory test instrument and find out within the flaw source, the flaw that produces behind definite especially output sensor.
The special priority application of computer comprises that in the flaw dictionary electronic databank is suitable, and allows computer to find out the flaw source by expert system, mainly in input sensor proparea and output sensor back zone or position between two sensors.Particularly computer can preferentially be inferred the source of multiple flaw, particularly flaw reason, flaw place and/or flaw kind.The flaw kind here can be regarded as strict periodic flaw of periodic and non-strictness (by the spectrogram analysis) and flaw (by the curve map analysis) at random.Yet, at this moment can position by the spectrogram evaluation of the laboratory test Instrument sensor mentioned in the past and the additional name of curve map evaluation at the output back segment.Because as broad as long relevant therewith of the spectrogram of input and output sensor with curve map.
In the electronics storage dictionary of being mentioned, preferential is to comprise flaw source and influence thereof all known on standard spectrum diagram and the canonical plotting.In the evaluation of so far output spectrogram (output curve map), occur doubling clear, comparative evaluation by input and output spectrogram (or corresponding curve map) being excluded especially, as exist two kinds of possible flaws, wherein a kind of possible flaw source is before the input sensor, and another kind of possible flaw source is behind the input sensor.Dictionary can be according to the present invention the information of comparative evaluation, flaw will double clear the eliminating and accurate explanation flaw source in two sections.
The display screen that this is particularly mentioned has been considered diagrammatic representation in advance to the operator, to the measure of operator's demonstration about taking, and where necessary to the suggestion order of operator's demonstration about taking measures.Computer or central computer can be preferential in this situation, if by-so-inquiry and advise next step logic action from the corresponding input of operator.New under complicated situation, can reach a kind of step-type flaw of finding out, reach the purpose that disconnects flaw then.
For example showing a kind of periodicity to the operator, is not orientable immediately flaw, and suggestion at first changes the total draft that disconnects when regulating.Do not move as periodic flaw, its reason may be down the front roller defectiveness, is the front roller defectiveness or turns to the top roller defectiveness.After also the possibility flaw is created in the drafting system material outlet, perhaps have a kind of so-called false flaw, for example be created in the bar tube reserves.Periodically flaw moves when total draft changes, and suggestion is to change preliminary draft under the situation of constant at total draft.As at this moment periodically flaw do not move, before flaw is created in the fibrous material inlet, by rear roller down or go up rear roller or enter drafting system by the drafting system transmission.It is middle roller or upward middle roller defectiveness down that the periodicity flaw moves.
The processing of one or more wavelength is to take out in the spectrogram of laboratory test instrument, handles a kind of independently invention viewpoint of expression, and this viewpoint is described in all claim 23 and 24.At least two or three spectrograms or curve map do not need comparative evaluation in viewpoint of the present invention yet.More precisely, independent viewpoint of the present invention relates in the spinning preparing machine computer the especially evaluation of spectrogram data (perhaps curve diagram data); The data of being obtained are outside, promptly by means of the help of laboratory test instrument, for example use the uster tester device to obtain.The operator can to submit significant data or data circuit (cable, radio and infrared ray etc.) to be to be responsible for these information transmission by handling according to the operating unit of spinning preparing machine of the present invention.The wavelength of laboratory test instrument spectrogram particularly, can be by means of the help of flaw dictionary Computer Analysis from machine, in the access of flaw dictionary, and wavelength points out the reason of flaw and the concrete prompting of getting rid of flaw preferably is provided for the operator at the display screen of machine.A kind of in corresponding Machinery Design automatically flaw get rid of and can stipulate that promptly the operator does not participate in, the automatic intervention that only may be asked about and must approval whether agree to determine.
Together with last-mentioned invention viewpoint, the help by means of the laboratory test instrument for example appears, can handle fiber from the spinning preparing computer in conjunction with the measuring light spectrogram of strip section, on uncontrollable drawing frame, carry out.After analyzing aspect the computer, the operator can draw corresponding output flaw prompting so.In adjustable drawing frame, particularly have the drawing frame of single transmission, can realize automatic debug adjusting in case of necessity.
Superiority of the present invention is further deepened, and will illustrate by the feature of following claim.
Description of drawings
Fig. 1 is the schematic side view of a drawing frame;
The specific embodiment
The present invention elaborates according to a unique schematic diagram below, the figure shows the schematic side view of a drawing frame, the example of this drawing frame more accurate say so spinning machine or spinning preparing machine.According to examples show a plurality of untwisted basically fiber skein FB (fiber skein is herein only made in front) that adjoin in the drawing frame, may be only to import a kind of fiber skein FB on the drawing frame equally, it be directly to be obtained by a preposition carding machine or combing machine.Settled a horn mouth 12 at the inlet of drawing frame in order to the compacting fiber strip.Also can select to use another kind of compaction apparatus.In addition, fiber skein is through the member scanning means 2,3 of input sensor 1, and this moment, a plurality of single fiber skein FB became the fiber skein FB ' of compression, entered drawing frame core drafting system 4.Drafting system is usually by three drawing machines or three pairs of rollers, real drawing-off has taken place between drafter or three pairs of rollers, drafter is that rear roller is to 5a, 5b, middle roller are to 6a, 6b and front roller to or claim delivery roller to 7a, 7b, roller to the rotating speed of rotation accordingly in order in to improve.The drawing-off degree of fiber skein FB ' and peripheral speed are than conforming to.In addition, meaning of the present invention is that also the fiber skein of supatex fabric is the fiber bonding.
Rear roller is to 5a, and 5b and middle roller are to 6a, and 6b has constituted so-called preliminary draft district, and middle roller is to 6a, and 6b and front roller are to 7a, and 7b has constituted so-called main drawing area.In uncontrollable drawing frame, in drafting process, not only all kept constant, and in adjustable drawing frame,, realized on the contrary disconnecting and regulated owing to passed through the change of drawing-off height in the preliminary draft district but also at main drawing area.In addition, in an adjustable drafting system, not only can change preliminary draft but also can change dominant draft, but chop and change dominant draft almost.Its reason be the change of dominant draft greater than preliminary draft so that can be used as one and regulate more accurately.
Usually settled a pressure bar 8 that fiber skein FB ' is turned in that main drawing area is additional, thereby fiber better led, particularly not at two rollers to clamping fiber (so-called floating fiber).The fiber skein FB ' of drawing-off turns to deflector roll 9 and a slivering machine device 10 to be merged by means of one, and passes through pressure roller to 13,14 and wobble channel 16, is placed on the rotating disk 17 with the angular velocity omega rotation, makes fiber skein with certain speed V
L Enter bar tube 18.
Fluctuation for balance strip weight on adjustable drawing frame, common mode is the scanning means of the fiber skein FB of displaying through draft of drawing frame device 4 fronts, scanning means is made up of two disk scanners 2 and 3 in an illustrated embodiment, and disk scanner also is the part of strip transvers section measuring device simultaneously.Disk scanner 2 is designed to fixed, and when disk scanner 3 utilized pressure to press to disk scanner 2, disk scanner 3 in the direction perpendicular to rotating shaft deflection had taken place.In this case, the deflection size of disk scanner 3 is exactly fiber skein FB ' cross sectional dimensions, and fiber skein enters between two disk scanners.In described form of implementation, disk scanner 3 links to each other with a corresponding measuring cell 20 (measurement value transformer), its output signal is at first to export on a storage device 21 with voltage signal, this storage device has considered that the strip section is at process scanning means 2,3 and enter the progressive error that taken place between drafting system 4 inlet and time difference (the FIFU memory-first-advance-first-go out memory), after the time difference warp, continue to be delivered to evaluation unit and regulon 22 so.Therefore evaluation unit and regulon 22 send control instruction, and by changing middle roller to 6a, the peripheral speed of 6b changes rear roller in case of necessity to 5a, and the peripheral speed of 5b is with the fluctuation of balance strip weight.The fluctuation of dominant draft section strip weight, balance is to reach by the revolution that changes servo drive 23 under current situation, utilizes epicyclic gearbox 24 to produce the revolution of control during this drive unit.Main motor 25 drives epicyclic gearbox 24 control output end privileges, and disk scanner 2 and rear roller are to 5a, and 5b and middle roller are to 6a, and bottom roll 5a and the 6a of 6b are driven.The speed of the front roller 7a that drives from main motor 25 remains constant, and guarantees to produce accurate computable fiber skein.Same main motor 25 drives pressure roller 13, by another pressure roller 14 of friction-driven.
Similar to disk scanner 3,13,14 fiber skein FB ' that pass through make pressure roller 14 that deflection take place equally at pressure roller, and deflection for example can be measured by measurement of inductance instrument 15 (measurement value transformer).Pressure roller to 13,14 and measuring instrument 15 constituted output sensor 11.The test signal of measuring instrument 15 is transmitted on evaluation unit and the regulon 22, and these unit and two devices 28,29 link to each other and form spectrogram SE and SA.The electronic memory of the test signal of input sensor 1 is combined into integral body with device 28 in addition, set up the spectrogram SE of test signal, and install 29 electronic memories that contain the test signal of output sensor 11 equally, set up the spectrogram SA of test signal.Certainly electronic memory also can be from installing the member of opening in 28,29 minutes.
Two spectrogram SE, the evaluation of SA can be realized by the table base line.The function of time can utilize formula and statement translator-Fourier-parsing to change in frequency range so.The channel of single expression is for example 1024 or 2048.
Computer 30 (for example microprocessor) is connected on two device 28,29 back; Computer is used a corresponding soft program according to present embodiment, preferably two spectrogram SE, the SAs of identical fiber in conjunction with strip section apparatus 28,29 is compared mutually.Two spectrogram SE, SA do such processing where necessary herein, for example by concentrating and/or calibration, spectrogram can be appropriate one is being folded one laying, for example the height of the drawing-off of drawn fiber strip is herein compared with the fiber skein in the drafting system 4, is also noted that the fiber skein FB of not drawing-off.
In order to reach the purpose of evaluation, computer 30 access on database 31 is originated in order to pass through an expert system analysis evaluation flaw, and database has comprised one-maximum benefit and also has been self study-flaw dictionary.In the flaw dictionary, stored the reason of strict periodicity and the periodic strip flaw of non-strictness, particularly additional damaged roller, bearing and driving belt etc.Noticeable wavelength jut has appearred in spectrogram, rising through a plurality of passages appearance, prompt for the periodic flaw of non-strictness (drafting wave), for example be because drafting system is regulated defectiveness, drafting system load is low, and the top roller cover plate is improper or because the one-tenth strip device of drawing-off outlet is too narrow causes.The feature of the periodic flaw of strict periodic and non-strictness and additional flaw source are deposited with in the database 31, and use two spectrogram SE herein, and SA makes comparisons.
The primary and foremost purpose of the comparison of mentioning, main in the proparea of input sensor 1 in corresponding described embodiment, the back zone of output sensor 11 or between two sensors 1,11, local positioning is carried out in the flaw source.This input and output spectrogram SE, SA are one to be folded one and is laying.Find out its difference where necessary.If two spectrogram SE, SA are basic identical, point out same flaw in the same wave strong point, can give this and to point out, it is correct that the inner defectiveness of this illustrative material and drafting system are regulated, otherwise a kind of flaw occurs in output spectrum SA, and this flaw does not exist in the input spectrogram, this spectrogram is clearly indicated, exist between two sensors 1,11 on drawing frame that drafting system is regulated mistake or machine part exists defective.
Flaw in technical field is just analyzed according to the evaluation of output spectrogram SA.So the ambiguity in the spectrogram (for by the tangible flaw of spectrogram by different possibilities) be not soluble immediately, the flaw and/or the bar protonatomic mass that contain a plurality of superpositions especially as spectrogram, when particularly the CV value is not the best, so that spectrogram does not meet standard spectrum diagram and clearly outwards outstanding flaw-wavelength.Pass through the location possibility mentioned, become easily thereby make flaw determine also to make flaw to get rid of.
In addition, exist or new flaw occurs, preferably calculate a kind of suggestion order of function suggestion automatically or starting like this if any flaw, above-mentioned relative measures and and then during test to the comparison of spectrogram, can cause suggestion next time.The method of this repetition is made additional seeking advice in database, finally propose flaw by the suggestion of computer and get rid of.
In order to implement best automatic searching flaw, computer 30 is also imported definite information to the operator, so that can many better flaws location.The operator can use a kind of input unit 33 herein, and contact screen for example is so that computer 30 domination material parameters.Can consider in advance that also machine is putd question to the operator by display 32, whether flaw is sought and is wished automatically, so that the operator can make definite or negate.Last situation for example can occur, and has seen flaw or has recognized another kind of flaw as the operator.
In addition, a kind of uniformity inspection instrument as laboratory test instrument 27 (being illustrated on the work T of figure), for example particularly a kind of known uster tester device, can be used for fiber skein FB ' counter extensioin and that put into the bar tube in case of necessity and set up spectrogram, and according to an invention viewpoint comparison input and/or output spectrogram SE, SA, and the spinning preparing machine computer of being mentioned above the viewpoint utilization according to another invention 30 is made separate analysis (not making comparisons).For these two kinds of situations, always have at least a kind of longer fiber skein section under the laboratory condition of definition, to measure.
The use spectrogram compares, and preferably the fiber skein section that compares mutually is consistent, so that can make accurate report for definite fiber skein length in the time window of selecting.But this is not achievable at all occasions.Whether along whole fiber skein have periodic flaw, so that exist flaw in each strip section if for example depending on.The strip section that herein will compare does not need unconditionally consistent with each otherly, because in selecting very the precise time window, the flaw information of strip section is identical continuously.
By the operator according to second kind of situation about mentioning (the independent evaluation of laboratory spectrogram SL), for example find to have among the spectrogram SL of laboratory test instrument 27 the suspicious wavelength of a kind of mistake is arranged, the operator can enter into input unit 33 by manual input, wavelength is input to computer 30 (direction of arrow), and computer is engaged in the flaw analysis.This computer is preferentially caught the database 31 flaw dictionary of combination with it.The information of flaw source and/or flaw eliminating measure can be provided to the operator on display 32.Replace the manual operations input, have the numerical value of Laboratory Instruments 27 also can arrive computer through electronic data transfer.
The spectrogram SL of Laboratory Instruments 27 compares and can infer thereon to the spectrogram SA that is less than output sensor 11, whether the belt flaw is upwards caused by output sensor 11 air-flows, perhaps whether in the distance of 18 in output sensor 11 and bar tube, caused flaw, for example particularly in the strip storage level, caused.In last situation, the flaw value appears among the spectrogram SL of laboratory instrumentation 27, otherwise does not occur in input and output spectrogram SE, SA.
Aforesaid embodiment relates to spectrogram relatively.About substituting and additional evaluation of flaw (for example details and slubbing) response curve figure at random, be possible unconfined equally.
Modification of the present invention has been done explanation by figure, application that can be free from all inhibitions.Replace the input sensor 1 and/or the output sensor 11 of mechanical scanning, used a microwave remote sensor and cavity resonator respectively, utilize it just can find out the belt weight of contactless per unit length.The technical field of this microwave sounding does not need to do detailed explanation herein.Evaluation unit and adjusting unit 22 or equipment control device and computer 30 can be combined into one.The present invention is operable to uncontrollable or adjustable drawing frame and the spinning preparing machine that has drafting system usually.
