Description of the new model: [New technology belongs to the weaving] The new field of this creation is about the frictional fake dress set in the foreword of the first paragraph of the patent Qianwei of Qianzhi JT Ming, and Youguan J Pincong and related technology of 4 kinds of friction false twist device. New Background 10 A friction false twisting device includes a friction false twisting unit as disclosed, for example, in EP 0 744 480 and its power source. This is known as a friction and false twisting unit for falsely finishing synthetic fiber threads. It includes friction with overlapping unidirectional rotating discs. It is mounted on a shaft configured on a Kesan Xiaoli towel, and 1 by the Tangent point rotations formed between these discs twist the line. ， 15 纟 In this type of unit, the three rotating branch-shaped friction disc stacks • are strapped together and connected to each other, so that these disc stacks rotate in the same direction: the same speed. This drive is generated by an electric motor combined with this friction device and connected to the friction disc stack. To achieve this, a non-synchronous motor is usually used, which operates together with the motors of other friction false twisting units and has a common controllable power source (normally an inverter). In order to protect against damage caused by excessive load, each motor needs to have its own protection device, which protects electrical equipment from short-term surge current and permanent overload. For this purpose, someone uses, for example, a safety fuse and a bimetal fuse M283852 for each friction false twist unit. With regard to a reliable false twist finishing process and a recorded uniformly satisfactory yarn quality, this unit alone is not sufficient to prevent damage. 5 [What's new] Summary of the new type Therefore, the purpose of this creation is to further develop: the friction false twist device in the form described at the beginning to the extent that it allows detection and recording or notification not only of the protective function of electrical equipment but also of this The initial function of the friction false twist unit 10 is changed; and an appropriate technique for operating the friction false twist device. This purpose is achieved in this way in accordance with this creation: the friction false twist unit included in the friction false twist device includes a rotation speed sensor connected to a drive or friction device, so that the rotation rate sensor can continuously evaluate the signal. 15 The advantage of this creation is that it can detect sudden and continuous development failures. In this respect, the present creation takes advantage of the fact that electric motors suitable for use in a friction false twist unit have a characteristic of decreasing rate-torque. When the friction false twisting unit is loaded with an additional braking torque due to a failure, the additional load becomes apparent by a reduction in the rotation rate, and it is easily detected by the rotation rate sensor 20. For the purpose of further processing externally, the signal from this rotation rate sensor is directed outwards without being evaluated in a friction false twist unit by means of adjustment, control or monitoring. It is particularly advantageous to use a rotation rate sensor in conjunction with an asynchronous motor M283852, as there is a defined relationship between the load force and the slip in this case. This slip can be easily determined by the frequency of the rotation field and the measured rotation rate. However, direct current (dc) motors or synchronous motors are also suitable for driving friction devices. The friction device used here may include a stack of 5 discs driven by friction, or a friction belt, or a combination of a friction disk and a friction belt. This rotation rate sensor may be, for example, a sensor that operates on the principle of a speed measuring generator or similar, which emits a measurement signal that is substantially similar to the rotation rate. Another advantageous variation of the rotation rate sensor emits the number of pulses per rotation set by the driver 10 or, for example, a friction disc stack. These pulse sequences can be easily read and further processed by a digital signal processing device. In the example of a non-synchronous motor, this evaluation becomes very simple when the rotation rate sensor produces the same number of pulses per rotation of the motor as the number of pairs of poles of the motor. In this case, it is possible to form a parameter value proportional to the slip only by obtaining the difference between the sensor pulse frequency and the inverter frequency. In the creation of the friction false twist I, when the signals of multiple rotation rate sensors are jointly evaluated by the evaluation device, the friction false stroke unit is rotated; the speed monitoring is a particularly simple and economical 20 # When implementing an electrical installation, this rotation rate sensor can be connected to the evaluation device via a field bus system in a particularly advantageous manner. When a friction disc stack is used as a friction device, the rotation rate sensor can also be advantageously directly connected to the disc stack or a shaft on which the disc stack is mounted. This technique for operating the original creation of the friction false twisting device according to this creation 7 M283852 The technique includes steps to continuously monitor, for example, the rate of rotation of a slip or a value derived therefrom. Continuous monitoring does not mean that it must be implemented without interruption. Instead, when monitoring multiple signals of the rotation rate sensor, it will be economical and useful to sample and monitor the same periodically one after the other. 5 Once this technique detects a 芩 value formed by, for example, the rate of rotation of a slide, and exceeds the limit by a previously determined number of differences, this technique assumes a failure due to slowness or obstruction, and turns off this specific Mopin_ rice twist unit. This corresponds to protecting the motor by a safety fuse. In the further development of this technology, this monitoring continues in addition to having a narrower limit value by considering periods and quantities exceeding 10. In the case of less latency, it therefore makes it possible to effectively protect the drive from overheating. This corresponds to protecting the motor with a bimetal fuse bar. This is useful for * The strategy is based on the fact that the excessive temperature of the motor is due to the loss of power minus the cooling power and multiplied by the period of excessive load. Therefore, when the value of this parameter is higher than the threshold value, the difference between the parameter value and the threshold value can be calculated by integrating or adding to the integer the amount exceeded by the elapsed time, and by The integer is compared with the limit value and a fault is detected. In a further advantageous variation of the technology, this monitoring includes a historical development of a rate parameter such as a sliding 20 °. In a short period of time, the continuous increase of the two energy 20 indicates that, for example, a yarn overlap is formed near the friction disc stack. The increase in slip over a longer period of time may be caused, for example, by bearing damage in the friction false twist unit. In this example, the technology therefore responds by generating a fault signal. This technique uses different deer stags depending on the type of error signal. In the case of serious failure, the drive of this friction and false twisting unit may be damaged. M283852 Friction disc stacking may cause damage. You must immediately turn off the driver of the affected friction and false twisting unit. The above also applies to: When sliding exceeds a very high threshold during a short period of time, or a low threshold during a longer period of time. When the yarns overlap near the friction disc stack, it is also necessary to turn off this unit. In other cases, the fault signal only warns the operator to eliminate the fault at the appropriate time. In other developments beneficial to this creation, when assessing the quality of the yarn, the fault signals or parameters formed by the fault signals are stored and considered. Therefore, for example, the quality level of a yarn affected by one of the above-mentioned failures in its further processing is reduced. This also applies to the failure that does not cause the friction false twist unit to shut down. In a further advantageous further development of this creation, the rotation 15 speed values of all friction false twisting units collectively driven by the inverter in the friction false twisting device are averaged and supplied to the inverter during the adjustment process. This has the advantage that during the adjustment of the desired rotation rate of the friction dummy unit, the actually achieved rotation rate is typically unknown and can only be estimated, or the process must be optimized at a later time Finely adjusted during the period. However, in the case of averaging and returning these rotation speed values to the inverter and adjusting the average speed, it is ensured that the preset rotation speed is actually achieved on average on average. Since the converter operates a sufficiently large number of friction false twist units under normal conditions, and even the notable reduction of the rotation rate of individual units, it has only a slight impact on the average rate, so that subsequent adjustment interventions only cause the rest The rate of the friction dummy unit only increased slightly. 9 M283852 Brief description of the drawings In the following, the embodiments of the present invention will be described in detail with reference to the drawings. Figure 1 shows the friction false twist unit of the friction false twist device of this creation; Figure 2 shows the friction false twist device of the friction false twist device of this creation; 5 Figure 3 shows the time curve of the rate parameter in a fault situation; and Figure 4 shows the other The time slope of the rate parameter in a fault situation. I: Detailed description of the preferred embodiment of Embodiment 3 10 FIG. 1 shows the friction false twist unit of the friction false twist device of the present invention. This friction false twisting unit includes a friction configuration consisting of a plurality of friction disc stacks 2.2 and a plurality of shafts 2.1 for mounting the friction disc stacks 2.2. The unillustrated yarn advances through a cutting point formed between the discs 3 of the friction disc stack 2.2. This yarn is twisted by twisting it around the surface of disc 3, which rotates at the same rate as 15 at the same direction. In this configuration, the axis of these friction disc stacks 2.2 forms a prism and has an equilateral triangle as its bottom surface. The friction disk stack 2.2 mounted on the shaft 2.1 is used to rotate in the bearing block 4. The shaft 2.1 of the driving friction disk stack 2.2 is protruded from the other side of the bearing block 4. They are connected to each other by means of a tape drive 5, in this way these friction 20 disc stacks 2.2 are rotating in the same direction at the same rate. Furthermore, one of these shafts 2.1 is connected to the other belt drive 6, which connects this shaft to the electric motor 7. The cooperation of these two belt drives 5 and 6 causes the electric motor 7 to drive all the friction disc stacks 2.2. This creation is not limited to connecting the shaft 2.1 by a tape drive. The other 10 M283852 transmission technology is well known to those familiar with this technology and can be used in the process of this creation. It is also possible to use other friction devices such as friction belt drives. The voltage source line 8 connects the electric motor 7 to a controllable voltage source (not shown) 5 which may be a converter. Although a non-synchronous motor is preferably used, other electric motors such as a direct current (dc) motor or a synchronous motor may be used. A rotation rate sensor 10 is mounted on the shaft of the electric motor 7. In the meaning of this creation, the rotation rate sensor 10 can also be installed in the area of the friction device (such as the friction disk stack 2.2), which is shown in FIG. 1 as an alternative by means of yarn. Therefore, this rotation rate sensor can also be mounted on one of the shafts 2.1 or on one of the belt drives 5 or 6 by inserting its own belt pulley. This rotation rate sensor 10 provides a signal proportional to the rotation rate or a pulse sequence proportional to the rotation rate. This is advantageous when using a non-synchronous motor, and it is especially applicable when the rate-frequency ratio of this sensor corresponds to the rate-frequency ratio of the motor 15. The signal applied to the signal line 11 is a similar voltage or current signal proportional to the rotation rate, or a frequency proportional to the rotation rate. However, the rotation rate sensor 10 may also include a conversion module for a local area network. In this example, the signal line 11 is a connection to an adjacent network link. 20 Figure 2 is a schematic diagram of a friction false twisting device with multiple false

The controllable voltage supply (inverter 13 in this embodiment) generates a supply voltage which determines the rotation rate of the friction false twist unit, and which is transmitted via the voltage supply network 12. Each friction false twist unit 1 is connected to a voltage supply network 12 by its voltage supply line 8. The signal line 11 of this friction false twisting unit is star-c_ected by Y 11 M283852 to the rate evaluation unit i 6. In the case of a false twisting unit 期望, it is expected that there will be a very large demand for an electrically slow connection. In this example, it is advantageous when a network connection is used for the signal line ^ so that the signal line 11 must be lightly connected to the signal line network 15 at the junction 14. The signal line network supplies the rotating material signal to the rate evaluation unit 16. In this unit, the individual rotation rate signals are evaluated, and all the rotation rate signals of the unit are continuously monitored at the same time, or the individual rotation rate values are periodically sampled and evaluated. Depending on the progress of the data, it is additionally possible to convert the measured rate into a sliding value at this point. This result from the rotation rate evaluation unit 16 may cause, for example, the closure of the friction false twist unit 1. To this end, the fault shutdown monitoring unit 17 sends a signal to the shutdown signal network 19. In the same manner as in the case of the signal line network 15 for the rotation rate signal, this network may be a wye connection or a 15-area network. From the closing signal engagement 20 and the closing signal line 2m to the closing device 18, it disconnects the special friction dummy unit 1 in the event of a failure. When implemented as a local area network, it will be useful for carrying the bluffing line network 15 that carries the rotation rate, and it will be useful for closing the signal network 19, which 20 physically provides these two networks in a common path. The result of the rate signal evaluation unit 16 may also be caused, for example, in which the signal is displayed on the fault notifier 22 to the operator. This fault notifier 22 can be configured in a centralized or decentralized manner. With the integrated display, this fault notifier can additionally provide special operating instructions, such as displaying contamination in one of these friction 12 M283852 false twisting units 1. Also integrated in this rotation rate evaluation unit 16 is a device for averaging all rotation rate signals. In this respect, it is obvious to those skilled in the art that these rotation rate signals affected by the failure have not been used for averaging. The average speed thus determined is supplied to the converter 13, which is assumed here to be a converter with an integrated regulator. In this case, the current output by the inverter is adjusted via the voltage supply network so that the average value of the speed corresponds to a preset desired value. > In Figure 3, different curves of the rate parameters with respect to time are plotted. The rate parameter used in this case is sliding. In the case of non-synchronous motors, this slip is about the difference in the frequency of the rotating field between the frequency of the rotating field and the measured rate. In the diagram illustrated here, the frequency of this rotating field is assumed to be constant. In the case of a direct current (dc) motor, a no-load rate is used instead of rotating the 15-field frequency. The rise of this sliding signal 24.1 is due to a fault. The limit value 25 B is the load limit stored in the rate signal evaluation unit 16 in FIG. 2 and represents the driver's short-term excessive load. Once the sliding signal 24.1 exceeds this limit value, a signal is sent. This signal is sent to the fault shutdown monitoring unit 20 17 in FIG. 2. In addition, the shutdown signal network 19 in FIG. 2 transmits the shutdown signal to the closing device 18. Connected to the fault release friction false twist unit 1, and it closes the specific friction false twist unit. In addition, a failure signal can be displayed on the failure notifier 22 in FIG. 2. The curve of the sliding signal 24.2 intersects with the critical value curve 26. This critical value 13 M283852 curve is set as the limit value for permanent overload. The number of this sliding signal exceeding this critical limit 26 is integrated into the limit crossing area integral 27. This integral is shown in Figure 3 as the surface (area) under the sliding signal 24 2. Once this surface passes the limit at point 28, this particular friction false twist unit 1 will be closed as explained above. The monitoring described here uses this knowledge: there is a continuous relationship between slip, torque and power loss. This power loss conversion causes the drive to heat up, so turn it off to prevent overheating. Figure 4 shows two additional monitoring points. This figure has two Λ lines showing the sliding signals 24.3 and 24.4 in the upper part. The lower part of the figure shows the sliding signal for the $ 29 between the B inch and 31. The sliding signal 24.3 shows a slow rise and its derivative 29 falls into the restricted area 30. The restricted area 30 must be selected so that a slowly rising slip signal can be detected, for example in the case of bearing damage. In this example, the fault notifier 22 of FIG. 2 notifies the operator of the fault and its possible cause. The sliding signal 24.4 shows a rapid rise. This causes 31 to fall into the higher restricted area 32. This restricted area 32 has to be selected so that, for example, a yarn overlap formed in the friction false twist unit 1 can be measured. In this case, the specific friction false twist unit is closed in the manner described above.
