Abstract
The invention relates to a friction false twisting device for false-twist texturing synthetic yarns and a method for operating said friction false twisting device. Said friction false twisting device comprises at least one friction false twisting unit having a separate electric motor drive, supplied by a common controllable electric power supply system, for driving a friction means. According to the present invention, the rotational speed of the electric motor or friction means is detected by a speed sensor. The measurement signal of the speed sensor, which is integrated in the friction false twisting unit, is outwardly led to an external evaluation device. The speed of each friction false twisting unit can thus be evaluated and, in case of too strong a speed drop, only the corresponding friction false twisting unit can be switched off or a warning message can be transmitted to the operator. Speed monitoring prevents overloads of the friction false twisting units and permits defects, such as yarn windings or storage damages, to be detected. By averaging the speed values, the determined mean value can be input, as a controlled variable, in speed regulators comprised in said controllable electric power supply system.
Description
Technical field
The present invention relates to a kind of friction false twist device and a kind of method that is used for moving friction false twist device by claim 1 preamble.
Background technology
Friction false twist device comprises for example by the friction false twist unit known to the EP0744480 and its supply unit.Be used for making the false twist texturized known friction false twist unit of synthetic thread to comprise that one has the friction mechanism that a pile overlaps the to each other the dish of equidirectional rotation respectively, these dishes are arranged on the axle on the summit that is installed in an equilateral triangle abreast, on the dish by the wedge that between dish, forms by be rotated in apply on the long filament twisted.
Here three rotatably mounted frictional disks heaps connect mutually in this wise by belt or the like, make the frictional disk heap equidirectional mutually and with identical rotating speed rotation.By a Vidacare corp driving that is equipped on friction mechanism and is connected with the frictional disk heap.Usually adopt an asynchronous motor, the motor of it and other friction false twist units is together by means of the common power supply that can control for this reason, a frequency converter normally, operation.
In order to prevent to transship the damage that causes, each motor must have the protector of oneself, and it protects electric device, has both prevented the overcurrent of short time, prevents long-term overload again.For example adopt a fusing fuse and a bimetallic fuse respectively for each friction false twist unit for this reason.
For reliable false twist texturing process with show that uniformly good long filament quality only prevents that apparatus from damaging is not enough.
Summary of the invention
Therefore the objective of the invention is; improve the friction false twist device of the described type of beginning as follows; promptly also can discern and write down or report the changes of function of friction false twist unit appearance, and develop a kind of appropriate method of moving friction false twist device by the pure defencive function of electric device.
Realize by such method that according to this purpose of the present invention the friction false twist unit that promptly is included in the friction false twist device has a speed probe that is connected with drive unit formula friction mechanism, the feasible signal of analyzing and processing speed probe continuously.
Advantage of the present invention is to detect the interference of emergent and continuous appearance easily.Here the present invention utilizes such fact, considers that promptly the motor that is used for the friction false twist unit has the rotating speed-torque characteristic curve that falls.If the friction false twist unit is because interference is subjected to an extra braking moment now, just descend and can observe by rotating speed so, rotating speed descends and can discern by speed probe.
The signal of speed probe is outwards drawn, so that do outside further processing, and does not need in the inner analyzing and processing of doing on adjusting, control or the monitoring meaning of friction false twist unit.
Speed probe and asynchronous motor are used in combination advantageous particularly, because there is certain relation here between loading moment and slippage, wherein skids and can be obtained easily by the frequency of rotating excitation field and the rotating speed of measuring.But dc motor or synchronous motor also are suitable for being used for driving friction mechanism.Here can adopt the overlapped frictional disk heap that obtains driving or the combination of friction belt transmission or frictional disk and friction belt transmission as friction mechanism.
For example can consider sensor by tachometer generator principle or the like work as speed probe, it sends the measuring-signal that is directly proportional with rotating speed basically of a simulation.
The another kind of good scheme of speed probe drive unit or for example each of frictional disk heap transfer the pulse of some.This pulse train can very convenient and accurately be read in and subsequent treatment by digital signal processing device.Particularly under the situation of asynchronous motor, if speed probe is in the pulse of motor revolution generation equal number, as the number of pole-pairs that motor has, just analyzing and processing is convenient especially so.Can form the characteristic value that is proportional to slippage by the deviation that forms simply between sensor pulse frequency and the frequency converter frequency in this case.
By in the friction false twist device of the present invention, the monitoring of friction false twist unit rotating speed can make things convenient for especially and realize economically a kind of, if the signal of the speed probe of many friction false twist units is jointly handled by an APU.
Speed probe is connected advantageous particularly on the APU by a local field bus system when carrying out electric installation.
The axle that speed probe also can advantageously directly be equipped on the frictional disk heap or be connected with the frictional disk heap when adopting the frictional disk heap as friction mechanism.
In by the method that is used for moving by friction false twist device of the present invention of the present invention, constantly monitor the numerical value that rotating speed or is derived out by rotating speed, as slippage.Here constantly monitoring is not understood to, and it must carry out incessantly.But when many signals of monitoring speed probe, in proper order their are inquired about and monitoring periodically, be significant at economic aspect.
If learn by the method, the characteristic value that is formed by rotating speed is slippage for example, and departure of predesignating of the value of overstepping the extreme limit just the method is thought owing to difficult road ability or stuck breaking down so, and is turned off relevant friction false twist unit.This is equivalent to by fusing fuse protection motor.
In the improvement project of this method, additionally in monitoring under the situation of considering excess load duration and transcend quantity size in a narrow limiting value scope.Just can prevent effectively when less difficult road ability that thus drive unit is overheated.This is equivalent to by bimetallic safeties protection motor.Effectively monitoring scheme depends on such fact, i.e. motor temperature rising subtracts cooling power by power loss and takes advantage of duration of overload to obtain.If characteristic value is positioned on the threshold value,, and relatively draw error by the integrated value that obtains like this and limiting value just the deviation between characteristic value and the threshold value can become an integrated value by the time integral or the accumulation calculating of plussage so.
Utilize the rotating speed characteristic value in the another kind of good scheme of this method, for example the function of time of slippage is monitored.For example at short notice slippage increase continuously may represent to produce the long filament that forms around the frictional disk heap disorderly around.One in the long period section increasing slippage for example may be because the storage in the friction false twist unit damages causes.Here this method is correspondingly reacted by producing an error signal.
Different this method according to the error signal kind are taked different reactions.For causing the serious mistake that the friction false twist unit damages at drive unit or frictional disk heap place, stop the drive unit of relevant friction false twist unit immediately, if slippage surpasses a big threshold value at short notice, perhaps surpass a less threshold value in a long time, this situation just occurs.Equally form around frictional disk heap long filament disorderly around the time false twisting unit also stop.
Under some other situation, only send fault warning, so that fix a breakdown at the appointed time to the operator.
The characteristic value that in a kind of good improvement structure of the present invention, stores error signal or forms by error signal, and when evaluating the silk thread quality, take in.The silk thread that for example occurs above-mentioned mistake when its subsequent treatment is demoted during at qualitative classification.For the mistake of not turning off the friction false twist unit too.
In the another kind of good improvement structure of the present invention, obtain in the friction false twist device all by the mean value of the tachometer value of the friction false twist unit of a frequency converter centralized driving, and flow to frequency converter, to regulate.This has such advantage, promptly scarcely knows the rotating speed of in fact realizing when adjusting the theoretical rotational speed of friction false twist unit, and can only estimate or accurate adjustment during process optimization afterwards.Obtain mean value and feeding back to frequency converter, then opposite when regulating mean speed, guarantee to reach actually the mean speed of regulation.Because usually the quantity of the friction false twist unit that drives with a frequency converter is enough big, the rotating speed that single false twisting unit is big descends and has only little influence for mean speed, so has only little rising by the rotating speed of following all the other friction false twist units of adjusting measure.
Description of drawings
With reference to the accompanying drawings an embodiment is done more detailed explanation.Accompanying drawing is represented:
Fig. 1 presses a friction false twist unit of friction false twist device of the present invention,
One of Fig. 2 presses friction false twist device of the present invention,
The time graph of Fig. 3 tachometer value under error situation,
The time graph of Fig. 4 tachometer value under another kind of error situation.
The specific embodiment
Fig. 1 represents a friction false twist unit by friction false twist device of the present invention.Friction false twist unit 1 has one by many frictional disk heaps 2.2 and many axle 2.1 friction mechanisms of forming that are connected with the frictional disk heap.Here unillustrated long filament is passed in the wedge that forms between the dish 3 that is contained on the frictional disk heap 2.2, and twisted by equidirectional periphery with the dish 3 that rotates with identical rotating speed.Here the axle of frictional disk heap 2.2 is tightened a prism with equilateral triangle bottom surface.
Frictional disk heap 2.2 usefulness axle 2.1 can be rotated to support in the bearing block 4.Axle 2.1 opposite sides from bearing block 4 that drive frictional disk heap 2.2 stretch out, and interconnect by this way with a belt transmission 5, and it is 2.2 equidirectional and rotate with identical rotating speed to make frictional disk pile.One of this outer shaft 2.1 connects with another belt transmission 6, and it makes axle be connected with motor 7.Acting in conjunction by two belt transmission 5 and 6 impels motor 7 to drive all frictional disk heaps 2.2.
The present invention is not restricted to belt transmission connecting axle 2.1.For other drive methods of professional is well-known, can use equally on meaning of the present invention.Equally also can adopt other friction mechanisms, for example friction belt transmission.
Make the unillustrated controlled power supply of motor 7 and here by power line 8, for example frequency converter connects.Pay the utmost attention to asynchronous motor as motor, but also can consider other motor, for example dc motor or synchronous motor.
On the axle of motor 7, a speed probe 10 is installed.Also can imagine and in meaning of the present invention, speed probe 10 is installed in friction mechanism, for example in the zone of frictional disk heap 2.2, can be as dotting as a kind of selection scheme among Fig. 1.Speed probe also can be installed on the axle one of 2.1, or is installed on a belt transmission 5 or 6 by inserting himself a belt pulley.The speed probe 10 otherwise signal that is proportional to rotating speed is provided, otherwise the pulse train that is proportional to rotating speed is provided.This is favourable under the situation that adopts asynchronous motor.If particularly the speed-frequency of the speed-frequency of sensor ratio and motor is this situation than consistent.The signal that is applied on the holding wire 11 both can be aanalogvoltage or the current signal that is proportional to rotating speed, also can be the frequency that is proportional to rotating speed.But it is contemplated that also speed probe 10 comprises a modular converter that is used for localized network.Holding wire 11 is the joints that lead to nearest network connection device in this case.
Fig. 2 schematically illustrate one have a plurality of friction false twist units 1 by friction false twist device of the present invention, a controllable power supply is a frequency converter 13 in this example, produces a supply voltage of determining friction false twist unit rotating speed, it is by power generating facilities and power grids 12 outputs.Each its power line 8 of friction false twist unit 1 usefulness is connected on the power generating facilities and power grids 12.The holding wire 11 and 16 Y-connections of tach signal APU of friction false twist unit.Under the situation that a lot of friction false twist units 1 are arranged, need to estimate big separated time expense.If it is favourable adopting a network joint for holding wire 11 in this case, make 11 needs of holding wire insert signal gauze 15 with a tapping device 14.
Signal gauze 15 is guided to a tach signal APU 16 with tach signal, there otherwise by the method for all tach signals of continuous monitoring simultaneously, otherwise, carry out the analyzing and processing of each tach signal by the method for cyclic polling and the single tachometer value of analyzing and processing.Here can the rotating speed of measuring be converted into slippery difference according to the subsequent treatment of data in addition.
The result of tach signal treating apparatus 16 for example may cause turning off in the friction false twist unit 1.Cut off supervising device 17 by fault for this reason and send a signal to shutoff signal net 19.As be used for the signal gauze 15 of tach signal, here also may otherwise involve a Y-connection, otherwise involve localized network.Shutoff signal line 21 leads to a cutoff device 18 from shutoff signal tapping device 20, and it turn-offs relevant friction false twist unit 1 when fault is arranged.
Under situation about realizing as LAN, for the signal gauze 15 and shutoff signal gauze 19 of tach signal, it is favourable that two nets are arranged on the common network physically.
The result of tach signal APU 16 for example also may cause, 22 couples of operators give the alarm with a fault alarm, fault alarm 22 both can have been concentrated and also can disperse to be provided with, can give special operation indicating by the centralized displaying fault alarm in addition, for example the prompting of polluting about friction false twist unit 1.
The foundation of the mean value of same all tach signals also is integrated in the tach signal APU 16.Here the professional knows certainly, is that the tach signal that contains fault is not used for calculating mean value by recognition.The rotating speed mean value of obtaining like this flows to frequency converter 13, supposes in this case that wherein this is a frequency converter that has built-in adjuster.Here mate in this wise by the electric current of frequency converter 13, make the theoretical value that rotating speed mean value is equivalent to stipulate by electric power network output.
The different curves of rotating speed characteristic value have been marked among Fig. 3 about the time.Here adopt slippage as the rotating speed characteristic value.At slippage under the situation of asynchronous motor is deviation between rotating excitation field frequency relevant with the rotating excitation field frequency and the rotating speed measured, is that constant is as prerequisite with the rotating excitation field frequency among the figure wherein shown here.
Here under the situation of dc motor, replace the rotating excitation field frequency with idler revolutions.
Slippage signal curve 24.1 is owing to a mistake rises.Limiting value 25 is stored in the tach signal APU 16 among Fig. 2, and the expression drive unit is for the load limitation of momentary overload.In case slippage signal 24.1 values of overstepping the extreme limit just trigger a signal, the fault that this signal is transferred among Fig. 2 is cut off supervising device 17, send a cut-off signals for the cutoff device 18 that is equipped on the friction false twist unit 19 that mistake takes place by shutoff signal net 19 there, cutoff device turn-offs relevant friction false twist unit.Can show a fault warning on the fault alarm 22 in Fig. 2 in addition.
Slippage signal curve 24.2 surpasses a threshold value 26 of adjusting as the long term overloading limiting value.The plussage of the slippage signal value of going beyond the limit of exceeded threshold 26 is integrated into the limiting value plussage 27 of an accumulation.This integration is expressed as the area below the slippage signal 24.2 in Fig. 3, in case this area surpasses the limiting value at 28 places, position, so relevant friction false twist unit 1 just turn-offs as the front is said.Promptly there is the continuous functions relation in the such knowledge of monitoring utilization described here between slippage, moment of torsion and the power loss.The conversion of power loss impels drive unit to heat up, therefore turn-off prevent overheated.
Fig. 4 represents two control points in addition.Two curves 24.3 and 24.4 of representing the slippage signal at upper area.The time-derivative 29 and 31 of representing the slippage signal at lower area respectively.Slippage signal curve 24.3 has a slow ascent stage, and its derivative 29 drops within the limit range 30.This limit range 30 is so selected, and makes for example can be detected at the slippage signal that stores the slow rising that occurs when damaging, and reports that to the operator fault is together with possible reason by the fault alarm shown in Fig. 2 22 in this case.
Slippage signal 24.4 has quick growth section, and its derivative 31 drops in the higher limit range 32.This limit range 32 is selected like this, make for example can detect the long filament that forms around friction false twist unit 1 disorderly around.Turn-off relevant friction false twist unit 1 in foregoing mode in this case.
