In this case, the vibration information is not sent through the signal line 2b and is sent from the wirelessly rotating turret board to the frame portion of the fixed portion, or is taken out through the slip ring at the rear of the winding device. The signal is sent to the local station 3 via the signal line 2b. Each local station 3 processes the vibration information transmitted from the vibration pickup sensor in a predetermined format of each winding device group, compares it with a preset alarm value, and issues an alarm if necessary. , L that spread the information in the factory
Information is transmitted to a center station 5 described later via the AN 4.

The frequency analysis of the vibration information may be performed by the center station 5.

In many cases, the host computer 8 has a mission of controlling the entire factory, and has a function of managing and controlling the amount of yarn wound by the winding device according to the present invention. The station 3 and the center station 5 may also be omitted as appropriate.

When the vibration pickup sensor 2 is mounted on a non-movable part, a frame 1a as shown in FIG.
A turret board 1b rotatably mounted on the turret board 1b has two bobbin mounting spindles 1c and 1c 'rotatably mounted thereon, and a traverse mechanism 1r mounted on the frame 1a.
In a turret-type winding device having a structure in which a roller bale and a roller bale 1s are provided so as to be able to move up and down, the vibration pickup sensor 2 is mounted on the side of the frame 1 which is a position near the bearing of the spindle 1c or the bearing of the turret b. Have been.

When the vibration pickup sensor 2 is mounted on the movable part, as shown in FIG.

The vibration pickup sensors 2, 2 'can be provided at bearings 1f, 1f' of shafts 1e, 1e 'of the spindles 1c, 1c' and bearings of electric motors 1g, 1g '.

Next, a method of capturing vibration information from the winding device according to the present invention will be described with reference to FIG.

First, when the yarn winding amount of the winding devices belonging to the winding device group reaches a predetermined amount, a host computer 8, which controls and integrates the entire factory, issues a yarn switching signal to the group 1.

The signal is transmitted to the center station 5 via the line 9 and at the same time to a yarn switching controller of a winding device (not shown).
Thread switching is performed sequentially from -1.

The spindle which is waiting in the winding device 1 starts running, and when a predetermined speed (in most cases, a predetermined winding speed) is reached, the speed is detected and a signal is sent to the local station 3-1. The winding device 1-1 is connected by the wire 2b.
Pick-up sensor 2-1 attached to
The current vibration information from (not shown) is captured.

The captured vibration acceleration information is branched into two in the local station 3, one of which is passed through only a vibration information of a corresponding frequency by a band-pass filter of, for example, 5 Kz to 40 Kz. The vibration waveform is subjected to envelope processing, and is converted into a waveform having a lower frequency than the waveform frequency band at the time of passing through the band-pass filter.
Further, the amplitude value of the highest-lowest amplitude [peak
Peak value (A)] and the area average value (B) of the vibration wave. The other one is processed as it is to the peak-to-peak value (C).

In the local station 3-1, (A0) for the peak-to-peak value (A) and (B0) for the area average value (B) of the vibration wave are separately set as alarm setting values in advance. , (C0) for the peak-to-peak value (C) is determined, and the value obtained by processing the sequentially acquired vibration information is compared with the alarm set value. If it is higher, an alarm is issued, and the data is sent to the center station 5 via the LAN 4, where it is sequentially stored in the storage device 6 in the form of an enveloped low-frequency waveform and a waveform as captured.

If the value is lower than the alarm set value, the alarm is not issued and is sent to the center station 5 via the LAN 4 without any change. Each is sequentially stored as a waveform.

When the spindle bearing in the winding device is damaged, the peak-to-peak value (A) is obtained.
Is particularly large, and when the bearings are worn down overall in an average favorable condition, the area average value of the vibration wave (B)
Increases. When the dynamic balance of the spindle is lost, the value of the peak-to-peak value (C) increases. Therefore, by accumulating these values over time and observing the tendency of the values, it is possible to determine which part of the winding device is getting worse and will soon reach the value of the abnormal alarm value or Condition continues,
It is possible to guess at an early stage that a situation such as an abnormal situation has not yet been reached.

The alarm value at this time should be determined in consideration of various conditions, but it is generally desirable that the alarm value be about three times the vibration value in a normal state. With such an alarm value, even if the vibration amplitude increases and becomes larger than the alarm set value when the bearings or the like begin to become abnormal, then the bearing will seize and stop in a short time, and will not lead to an accident. Is common.

If the bearing size used in the winding device is used under the load condition, if the vibration value is about three times the normal vibration as the alarm value, the alarm is issued. Some literature can calculate that a bearing will break approximately 1 to 1.5 months after it is emitted. Therefore, it is natural that, in many cases, there is no problem even if a measure is taken after an alarm is issued and the winding device reaches an abnormality.

When the alarm value exceeds the alarm set values (A0) and (B0) and the alarm value is generated, the envelope-processed low-frequency waveform is converted to an FFT (Fourier transform).
, It can be seen that the output value of the specific frequency is prominent as shown in FIG. In many cases, this behavior indicates that the bearing has been damaged and abnormal vibration has begun to occur. In such a case, since the calculation can be performed in the case where the damage is simple from the data such as the shape of the used bearing (the dimensions of the inner and outer rings, the number of balls, etc.) and the number of revolutions,
In the initial stage, it can be estimated from the information shown in FIG. 5 which part of the used bearing has started to be damaged.

On the other hand, in a normal vibration state in a normal bearing, even if the vibration waveform subjected to the same processing is applied to the FFT, a large output value at a specific frequency is not observed as shown in FIG.

5 and 6, the vertical axis MAG (mV) indicates the output (voltage: mV) of the vibration pickup sensor.
The horizontal axis KHZ indicates a frequency value.

FIG. 7 is a view showing waveforms which are obtained by sequentially processing the vibration information from the winding device along the process of winding the spindle in the winding device in which the phenomenon shown in FIG. It can be seen that the vibration output value generated by the damage of the bearing decreases as the winding layer increases. The sampling interval of this data is 10 minutes. On the other hand, FIG. 8 shows the information obtained by processing the vibration information from the winding device which is considered to be normal in the same manner, and displaying the waveforms obtained by applying the FFT.

From these facts, it is desirable that the vibration information is collected at a time when the winding layer is thin in order to grasp a change over time of the winding device. One of the most desirable vibration information capturing points is, for example, when the approach spindle reaches a predetermined speed (before the spindle that has completed the approach comes into contact with the roller bale, or when the standby spindle starts the approach at the standby position, (When a predetermined speed is reached). At this time, the vibration information from the spindle during winding is 1/3 to 1 with respect to the vibration information from the approaching spindle during high-speed rotation.
/ 4 low frequency, abnormal output signal is also thin,
Vibration information from the newly high-speed rotating approach spindle becomes dominant. The vibration information obtained at this point is excellent in reproducibility, and also because the external noise given to the rotating spindle is small, the S /
This is vibration information having a high N ratio, which is preferable. However, it can be understood from FIG. 7 that the thread may be started after winding.

When a value exceeding the alarm set value is measured, an alarm is issued immediately at that time, or when an alarm value is continuously exceeded a plurality of times. There are various methods of issuing an alarm, such as issuing an alarm when the ratio of the number of occurrences exceeds a certain value. They are determined in consideration of the surrounding circumstances.

A very short time is required for capturing and processing the vibration information at the time of yarn switching of the winding device. Therefore, the vibration information of the winding device operating in the factory is sequentially sampled using the time other than the data collection / processing time. If there is a spindle or the like in which the winding layer has begun to collapse and an imbalance is starting to occur and there is a winding device whose amplitude is higher than the normal vibration amplitude value, the information is collected. At this time, the vibration information from the vibration pickup sensor is processed into a predetermined form without applying the band pass filter, and then a preset alarm value (D0) [possibly the same value as the alarm set value (C0)] Is compared to The taken vibration information value is compared with the set alarm value, and if it is lower, the vibration information of the next winding device is collected without any treatment. If a relatively high value is detected, an alarm is issued by the same determination method as described above, or the alarm is issued and the winding device is stopped at the same time.

The function of the local station 3 for specifically processing the vibration information taken from the winding device will be described with reference to FIG.

A multiplexer 11 is provided from a vibration pickup sensor 2-1, 2-2, 2-3, etc. installed in the winding device.
When connected to the circuit 14 by the second multiplexer 12, the vibration information collected in the order instructed by (1) is branched into two vibration information 16 and 17 via a branch point 15.
The vibration information 17 is directly used as the peak-to-peak processing device 1
At 8 it is converted to a peak-to-peak value (C). The vibration information 16 is a bandpass filter 19 of 5 KHz to 40 KHz.
, And then processed into a low-perimeter waveform by an envelope processing device 20 (envelope processing can also be performed by software processing). The processed waveform is then processed
Is converted to a peak-to-peak value (A). The waveform processed in the same manner is converted by the waveform processing device 22 into an average area value (B) of the vibration wave. The values (A), (B), (C)
Are the set alarm values (A0), (B0
) And (C0) are compared by the determiner 23. If the value is higher than the set alarm value, an alarm is issued based on the above-mentioned judgment criterion, and in some cases, the winding device is automatically stopped.

Set alarm value (A0), (B0), (C0)
After the comparison, the data is sent to the center station 5 via the LAN 4 and sequentially stored in the storage device 6 in a predetermined format.

When an abnormality is generated and an alarm is issued, or when it is desired to confirm the current state of the winding device as data, the center station 5 is operated in a predetermined manner to obtain the data shown in FIGS. The time-dependent vibration change behavior of the winding device as shown in FIG. 9 can be displayed on the display device 10 for viewing. From the behavior, valuable information such as the current situation of each winding device, the tendency of change, and the margin to the abnormal alarm value can be obtained. Further, it is possible to estimate a date when an abnormality is likely to occur from the change tendency chart.

As described above, the second multiplexer 1 of the local station 3 at a time other than the time of the signal fetch processing for observing the change with time at the predetermined time.
2 selects the circuit 13 side, and the multiplexer 11 sequentially looks at the vibration information during the operation of the grouped winding devices in a predetermined order, and the vibration information value is peak-to-peak processed by the peak-to-peak processing device 18. Converted to a peak value (C), and is compared with a predetermined alarm value (D0) by the decision unit 23. If the value is higher than the alarm value, an abnormality signal is issued based on the abnormality occurrence rule as described above, or at the same time, the operation of the abnormal winding device during operation is stopped.

If the value is lower than the abnormal alarm value, the multiplexer 11 switches without performing any processing and fetches the next vibration pickup sensor information and performs the same processing as described above.

It is needless to say that the technology of the present invention is not limited to the application of only the spindle, but can be uniformly applied to other high-speed rotating members such as a roller bale of a peripheral winding device, a thread feed god roll, and the like.

By using the above-mentioned technology, a regular maintenance method (Time maintenance method), in which a device which has been widely used in the past, performs regular maintenance before an accident occurs, is performed.
Based maintenance method) can be shifted to the condition-dependent maintenance method (condition based maintenance method) that performs maintenance in order from the equipment that has become rationally faulty.

That is, it is well known that the bearing life time described in a catalog of a bearing or the like is a time when an abnormality occurs in 10% of the whole, and the life of other bearings is longer.

In the case of the periodic maintenance system, maintenance is performed at a point in time before the first bearing abnormality of a group of winding devices occurs, and the devices that are still operating smoothly without any problem are simultaneously disassembled. In most cases, maintenance such as replacement of bearings was performed.

On the other hand, if the present invention is applied, only those in which signs of abnormality have begun to be seen are extracted and bearing replacement and other maintenance are sequentially performed. Is also operating as it is, and as a result, the maintenance cycle is greatly extended as a whole.

It is essential that a high-speed rotating body composed of many members, such as a high-speed winding device, be assembled and adjusted so that dynamic imbalance does not occur in the assembled state. For this reason, once the bearing is disassembled and replaced, the high-speed rotation characteristics like before cannot be obtained as it is, because of the change in the dimensions of the fitting part of the bearing part, the occurrence of imbalance due to reassembly, etc. It is often necessary to use advanced assembly adjustment techniques such as field balance correction.

Further, the yarn winding device of the present invention stores the vibration information sent to the center station 5 in the first storage device 6-1 as shown in FIG.
A second storage device 6 separately provided with the same vibration information
-2, and transmits the vibration information stored in the second storage device 6-2 to a monitoring center (a textile machine is installed by a textile machine) at a remote location using communication means 30 such as a telephone line, the Internet, and commercially available computer software. The management device 31 such as a computer installed in a management department other than the factory or a management department of a take-up device manufacturing company, a management department of a maintenance contracting company, etc.) can store and print out the data as required. By doing so, double monitoring can be performed in the monitoring section of the factory where the winding device is installed and the monitoring center in a remote place, and the winding device can be more reliably managed.

When the vibration information stored in the storage device 6-2 is fetched into the management device 31, the vibration information stored in the storage device 6-2 may be deleted or may not be output twice. In addition, it is possible to prevent the vibration information from being taken in redundantly.
