Description
Technical field
The present invention relates to a kind of spinning preparation machine, it has a drafting system that is used for drawing at least one fiber skein, especially a kind of carding machine, drawing machine or combing machine, it has at least one microwave remote sensor, is arranged on the import and/or the exit of drafting system, to be used for measuring the thickness of at least one fiber skein, this microwave remote sensor comprises at least one cavity resonance device, and is drafted in measuring process by at least one fiber skein of this cavity resonance device.The present invention also comprises a such cavity resonance device.
Background technology
In spinning industry, at first produced a kind of fibre structure of for example wool, become the yarn of a bending after through the series of process step, with as final products.This spinning machine, carding machine for example, drawing machine or combing machine, reverse arrangement on the manufacturing direction of yarn has the effect that the quality fluctuation that makes one or more fiber skein keeps balance.In order to reach this purpose, the fiber skein sensor is installed in, for example on the drafter, and being used for measuring the thickness of this fiber skein, that is fiber skein quality and fluctuation thereof.This sensor is also given regulon these transfer of data simultaneously, and this regulon can suitably be regulated the drafting component of at least one draft apparatus.Even in the drafter that can't regulate, thirsted for obtaining too in many cases about the data of fiber skein thickness fluctuation.If the thickness of this fiber skein is higher or lower than its threshold value, be arranged at a suitable sensor of draft apparatus outlet, sending one for example is that cutout response and/or alarm signal are to this equipment.
The known method that is used for measuring the fiber skein thickness fluctuation mainly is based on the mode of mechanical scanning.But the mode of action of these mechanical pick-up devices no longer has been applicable to the transfer rate of draft apparatus outlet, when especially surpassing 1000m/min.In addition, the strong mechanical compress of necessity of mechanical pick-up device front makes its negative on the drawing-off capacity seem particularly noticeable.
WO00/12974 discloses a kind of microwave remote sensor, to be used for continuous detecting in the textiles that moves of draft apparatus porch, the fluctuation situation of the thickness of its fiber skein.Alternatively or extraly, a microwave remote sensor is arranged at the exit of draft apparatus, the average quality that particularly its can display fibers raw material.
According to the described equipment of WO00/12974, comprise: a sensor for measuring temperature, to be used for compensating a temperature fluctuation by the processor generation, yet described design has its shortcoming, and that is exactly the whole measurement result of this temperature-compensating meeting influence, therefore this is not a best solution, because it is higher that it spends on the one hand, on the other hand, it is based on necessary empirical formula computational methods.
Summary of the invention
The problem that the present invention need solve is the accuracy of how fibres modified strip thickness measure in general weaving manufacturing works.
This problem solves at the initial spinning preparation machine of mentioning, it is by microwave remote sensor is set in measurement, and the cavity resonance device chamber wall of this sensor prevents that temperature conditions from changing and realizes.This problem is the cavity resonance device solves that has a cavity resonance device chamber wall by, and this cavity resonance device chamber wall has the material of low thermal coefficient of expansion by segmentation manufacturing at least by one.
The invention has the advantages that in fact, when using microwave, have the variations in temperature of certain influence being eliminated on the degree very much to certainty of measurement.Expensive computational methods solution also can be eliminated fully.
At this product when bringing into use, the temperature that reaches the surface in the machine is relatively low, but it can raise along with the time, the heat of machine motor and other moving meters increases especially, also have fiber skein can cause the rising of temperature, thereby make cavity resonance device chamber wall produce distortion in the friction in import of cavity resonance device and exit.The geometry deformation of this cavity resonance device can cause the change (by the cross structure of a unmodifiable fiber skein) of resonant frequency and the change of the measured value that thereupon produces and/or cause measuring inaccuracy.The accuracy of this measurement can be significantly improved by the equipment that changes according to the temperature conditions that prevents cavity resonance device chamber wall of the present invention.Thus, this machine is a period of time that just brought into operation or worked just to seem unimportant.On the other hand, if use a kind of single calculating compensation of temperature effect, at first, this temperature must be measured, and a specified temp of the representative of the appropriate point in finding correct curve.
Be applied to as described in the present invention in the cavity resonance device in the preferred embodiments of the present invention, cavity resonance device chamber wall is made by the piecewise by a kind of raw material of low thermal coefficient of expansion.The advantage of doing like this is, variations in temperature and expansion, and the contraction of cavity resonance device chamber wall can be controlled in the very little scope.On this connected, preferable material was to have a low thermal expansion characteristics energy, and it is about 1/5 of in the textile machine general steel that uses, is 1/10 better.This steel, for example the Ni36 steel contains the nickel of about 35-37% and other metals of less composition, and carbon, the perhaps another kind of steel similar to it.The Ni36 steel has an almost negligible thermal expansion, that is to say, and in the time of 20 ℃, the thermal coefficient of expansion of this steel no better than 0.This steel is named as invar at present knownly
Steel, other steel then has other trade name.In addition, the Ni36 steel also has relative elasticity except negligible thermal coefficient of expansion almost, that is to say, compare with ceramic material do not allow frangible,
If such material is used for cavity resonance device chamber wall, the composition of meeting and this cavity resonance device collides, and/or influence cavity resonance device frequency and amplitude thereof in the measuring transducer cavity, cavity resonance device inwall can manufacture one and has conductive layer so, and the thickness of this layer can be 5 μ m.
Another optional or extra advantage of the present invention is, uses a kind of heat sensor of heat insulator can most ofly reduce remaining number of sensors of machine.Such heat rejection can prevent to conduct to sensor from the heat of engine or the generation of other movable machine elements, thereby causes the change of the resonant frequency of volume and cavity resonance device.
In fact, such heat rejection, the aluminium book that for example insulate can be disposed in around cavity resonance device most.Alternatively or extraly, this sensor can partly coat with a kind of heat rejection shell.In another optional or extra design, be used for connecting the interface components of this sensor, fix, thereby the heat of this part conduction is cut off basically with the material of low heat conductivity to machine part.
Alternatively or extraly, as previously described prevent the equipment that cavity resonance device chamber wall temperature condition changes, a temperature active adjustment device can also be set.This can be so that have very big elasticity in the adjustment of these chamber walls.In this case, temperature can be adjusted to desirable scope, and not conceivable heating of a kind of cavity resonance device chamber wall or cooling can be cancelled.In order to reach this purpose, if so thermostatic target temperature can be conditioned, it will seem effective especially.
In order to realize above-mentioned adjusting, provide one or more and be used for measuring the interior cavity temperature of cavity resonance device and/or the temperature-measuring element of inner wall temperature is favourable.In order to reach this purpose, can pass through, for example a kind of thermal resistance measurement obtains the result of cavity resonance device chamber wall and/or temperature on every side.In addition, the measurement device of known a kind of like this economy, for example PT100 is fixed on the outer wall of cavity resonance device.Alternatively, can also use an inductance coil or other measuring methods that is fit to.
It is very favourable that described at least one temperature element (TE can be positioned on the fixed position, with the typical case as the behavior of whole cavity resonance device temperature.Alternatively, a plurality of temperature sensors are arranged on different positions, anticipate more suitably to be used for selecting whose signal.Fasten in this pass to help assessing and estimate that one represents temperature, as regulating temperature with a mean value or other.
If the air by the cavity resonance device is controlled under the steady temperature, in the temperature different distributions of cavity resonance device inwall, and not conceivable coarse temperature measurement result can be avoided to a great extent.This air-flow can be used for cleaning the inwall of cavity resonance device equally, especially eliminates the fiber that gets loose from fibre structure.
The target temperature of temperature active adjustment device is regulated and can be carried out in every way.For example, use a discrete control module in one embodiment.Alternatively or extraly, an evaluation unit combines with at least one microwave remote sensor, to be used for regulating temperature.And the machine central control unit can receive this thermostatic adjusting.
Especially advantageously, described temperature-adjusting device comprises, a heater, and the target temperature of cavity resonance device inwall is higher than machine and influence on every side valuably, and fricative temperature.Use the advantage of this heater to be, for example, a hotness coil can be attached on the quite large-area zone of outside of cavity resonance device.
Alternatively or extraly, at least one cavity resonance device inwall is heated.Thereby produce a hotness voltage.
Except heating cavity resonance device chamber wall, cooling agent can be used to regulate this temperature equally and make it to be lower than machine and influence on every side, and the temperature that rubs and produced.
Alternatively or extraly, cooling agent is used to provide a kind of cold airflow.Such air-flow can be used for cleaning the inner room of cavity resonance device and/or the machine part of connection equally.Under many circumstances, if this air-flow can be controlled under the constant temperature at cavity resonance device inwall, so, the even distribution of said temperature can realize at cavity resonance device inner chamber by this air-flow.
This temperature active adjustment device can independently cause the heating or the cooling of at least one cavity resonance device inwall, and the electric current of corresponding heating agent or cooling effect can reach desired value or be interrupted before this.If surpass or be lower than this desired temperatures, electric current is heated or cools off by closure again.When machine was configured to reach preferred temperature fast, its same advantage was, can regulate this heating or cooling effect.
This temperature-adjusting device preferably is designed to a Peltier element (Peltier element), to be used for heating or cooling off at least one cavity resonance device chamber wall.When being used for carrying out cooling effect, thus described at least one Peltier element the heat of cavity resonance device chamber wall take away make it the cooling.The temperature of described at least one cavity resonance device chamber wall can be maintained at below the temperature that realizes the tradition cooling significantly.
It also is in the cards that different cavity resonance device elements is regulated respectively.For example, the cavity resonance device surface can be cooled to one side of inner room, one side back to then can be heated.Corresponding cavity resonance device zones of different also there is no need to use same target temperature.But in measuring process, on the contrary, its purpose all is that the geometry of cavity resonance device is remained unchanged.
In measuring process, the combination that can in all sorts of ways of the various devices that are used for preventing the distortion of cavity resonance device.
A uniqueness of the present invention is characterised in that, can keep totally or by air flow cleaning of cavity resonance device.The intensity of this air flow and/or flow path can advantageously be regulated by an air flow controller.For example, the choke valve on the air entrapment element of described device.The A/F of described at least one choke valve can be regulated by manual or electronic.Especially, the automatic driving of described at least one choke valve can be implemented.The pollution level of cavity resonance device can be configured to controlling value, and in a favourable exemplary embodiments, this controlling value can be set with the sensor that is fit to.Such sensor can be, an optical pickocff for example, and this optical pickocff can receive owing to polluting increases the signal that dies down, and finally is lower than a threshold value.Other embodiment can be based on the measurement of the resistance value that depends on pollution, and this resistance value is the function of the thickness of pollution film on the cavity resonance device chamber wall or composite lubricating film.A kind of result who pollutes about inner chamber can optionally draw from cavity resonance device signal itself, and more advantageously when the cavity resonance device is cavity, the border of cavity resonance device characteristic (cavity resonance device quality) is surmounted.In this case, the evaluation unit of sensor advantageously sends an appropriate signals, to be used for controlling at least one choke valve of another air flow controller.
Described air-flow can be used as one and inhale a flow process or a wind drift journey.In addition, continuous flow or interruption air-flow can be used.Its time interval is periodically, perhaps sets according to the threshold values or the threshold value that surpass cavity resonance device pollution level or quality.
The order of continuous suction or the power that blows can be advantageously in time be adjusted to continuous or be interrupted at an operation stand (being called substrate) and/or the central control equipment in the spinnery.Same as above, air-flow continuously, be interrupted, intensity, flow paths etc. all are manually and/or automatically to regulate.
The advantage of another variation of this air-flow is that this air-flow is driven when container changes, because if there is not described container rapidly to change in continuous fiber skein production process, just do not have measurement so this moment and be performed on fixing fiber skein.If this has just proved that air-flow is that direct flowing along fibrous raw material is very favourable.Especially preferentially, air is controlled on the relative edge of fibrous raw material.Therefore, can guarantee that independent fiber and other pollution stages can be removed effectively.
Be used for cleaning and/or thermoregulator air-flow can directly be controlled.For example, suction can be applied in sensor as described above.Similarly, can in being centered around the housing of sensor, produce a kind of vacuum, and make it heat insulation by this air-flow.
Feature in further advantage of the present invention such as claims is described.
Details of the present invention will be further explained in conjunction with details and accompanying drawing subsequently.

The specific embodiment
A kind of Principles of Regulation of drafting system 1 will make an explanation by subsequent embodiment shown in Figure 1.The fiber skein 2 that inserts is that the fiber skein thickness of 6 fiber skein 2 is detected by a microwave remote sensor 3 in the porch of drafting system 1 here, and this microwave remote sensor carries out work (microwave generator does not indicate in the drawings) according to the principle of cavity resonance device.Funnel 18 is one to be used for compressing the compression set of this fiber skein 2, and it is connected in the front end of cavity resonance device.By behind the microwave remote sensor 3, by behind the microwave remote sensor 3, fiber skein 2 is with the form output (to the expansion of drafting system 1 triangle) of the wool that enters drafting system 1.In this embodiment, described drafting system 1 is right by a pair of inlet roller, a pair of in the middle of roller to one supply with roller to form (only showing that in the drawings descending roller is to 20,21 and 22).The drawing-off of fiber skein 2 is to realize by the fiber skein or the wool 2 that clamp between the right roller of each roller, and described roller is to being with the peripheral speed rotation that increases from the throughput direction of fiber skein.
The measured value of sensor 3 is transformed into voltage value by evaluation unit 4, and this voltage value is represented the fluctuation of fiber skein thickness, and stores memory 5 into.This memory 5 is a FIFO memory (push-up storage), and it postpones to be transported to theoretical value module 7 to described voltage with a preset time.In order to reach this purpose, memory 5 receives a series of pulses of being sent by an impulse generator 6, and it is the velocity measurement by the fiber skein 2 of sensor 3.Fiber skein from the inlet roller to being sent to here, thereby suitably pulse generator 6 and this roller to being coupled.Use the pulse of this impulse generator, the voltage value of sensor 3 is stored in the memory 5 according to the path that the fiber skein between sensor 3 and the drafting system 1a passes through.When the fiber skein of fiber skein bundle or wool 2 arrived the imagination drawing-off position in drafting system 1a drawing-off zones, corresponding measured value was stored that device discharges and a suitable position operation is performed, and this part content will be described in subsequent details.Interval between sensor 1 measuring position and the drawing-off position is called as the adjusting starting point.
Alternatively, impulse generator 6 can be right with another roller, for example one transmits the back (side that along fiber skein transmit look up) of roller to being coupling in sensor 3.In this embodiment, not right by the inlet roller, but by transmitting roller to transmitting fiber skein by sensor 3.
Yet theoretical value module 7 receives a guiding voltage from guiding rotating speed device 9.This guiding voltage is the right descending roller 22 speed measured values of supply roller, and described roller 22 is driven by sustainer.In theoretical value module 7, calculate a theoretical value then, and send control module 10 to.Carry out the comparison of an average theory value in control module 10, the actual value of regulating engine 11 is sent to actual value rotating speed device 12, and this actual value rotating speed device sends corresponding actual value to control module 10.In control module 10 theoretical value and actual value relatively be used to provide one with want the drawing-off that obtains to change corresponding very definite speed to give and regulate engine 11.Regulate engine 11 and drive planetary conveyer 13, thereby make the speed of the descending roller 21 that descending roller 20 that the inlet roller is right and middle roller are right change according to the smooth degree of fiber skein of expectation.Fiber skein thickness among the drafting system 1a is conditioned in so-called adjusting starting point, the drawing-off position that the speed symmetry that this adjusting starting point just is meant the sustainer 8 that counts described idle time and regulates engine 11 overlaps.
Other driving method, for example, single driving may realize (not describing) with its dependent variable herein.
Microwave remote sensor 30 is arranged in the delivery outlet of drafting system 1a, and connects from 19 following currents of wool pipe, and it is as a compression set in this preferred embodiment.Leave the fiber skein or the wool 2 of drafting system, by the calendering roller that connects from sensor 30 following currents to flowing out.The signal of sensor 30 offers evaluation unit 31, and this evaluation unit can send and transmit this voltage signal to control module 10 according to the thickness of drafted fiber skein 2 '.For example, the long-wave band of fiber skein 2 fluctuation expression drafting system 1a can regulate by the signal of sensor 30.Alternatively or extraly, the signal of sensor 30 is used for quality control, during this period, is exceeded or is lower than as a threshold value, and this machine can shut down easily.
Figure 1 shows that a temperature element ( TE 40,41 is arranged on the schematic diagram on the sensor 3,30, to be used for measuring the temperature of a cavity resonance device chamber wall or inner chamber.Some temperature-measuring elements also can be used equally to obtain an average temperature value.The temperature fluctuation that produced of machine opening and closing because the certainty of measurement of sensor 3,30 is subjected to, and the influence of machine works environment and the heating of cavity resonance device chamber wall, cooling are so a kind of suitable temperature control needs.
Temperature element (TE 40,41 is sent to evaluation unit 4,31 with the temperature value that records.In this exemplary embodiments, shown evaluation unit 4,31 can carry out temperature control equally, the temperature-adjusting device 14,15 that designs with observing and controlling correspondingly.If sensor 3 is arranged on the front end of drafting system 1a, evaluation unit 4 is regulated heater circuits 14, and this heater circuit 14 is used at least one cavity resonance device chamber wall of heating sensor 3.Alternatively, at least one hotness coil is connected in the heater circuit 14 that segmentation is centered around the cavity resonance device, preferably for keeping in touch (not indicating among the figure).It should be noted that these heaters can not cause any interference to the microwave resonance signal.
After machine is opened, keep the long duration steadily after, heater circuit 14 can be driven at once, thereby reaches needed heating-up temperature rapidly.The temperature that this target temperature can come a quite stable for a cavity resonance device chamber cornice, the temperature of this temperature and machine intimate, temperature around the machine is compared, and compares with the fricative temperature of cavity resonance device element with fiber skein if applicable, is relatively independent.At that time, under a such constant temperature, just do not have temperature conditions and change, thereby can improve the precision of measured value.
In the ordinary course of things, temperature-measuring element 40 records current temperature, and then, if this temperature is lower than a preset threshold value, evaluation unit 4 is regulated heater circuit 14.If measuring cell 40 temperature displayed surpass preset value, evaluation unit 40 sends a corresponding instruction and gives heater circuit 14, stops heating steps.
A kind of simulation heating method of respective design is provided, the drafting system exit that is used for sensor 30, evaluation unit 31 is being born the effect of controlling heater circuit 15 equally, and described heater circuit 15 is the temperature that are used for regulating at least one cavity resonance device of sensor chamber wall.
