Description

[Detailed description of the invention] [Industrial application field] This invention relates to a spinning winder.

[Conventional technology]

The winding speed of the spinning winding machine that winds up the spun yarn from the spinning beam has been increased (approximately 8000 m/min)
As a result, the maintenance management of the spinning winding machine has become more complicated and difficult, and therefore has become even more important.

For example, in the case of conventional winding machines that are relatively low-speed, the degree of wear and tear on movable parts such as the bobbin holder bearing and traverse cam bearing, or each drive motor can be determined to some extent based on conventional data and operator experience. If a guess is made based on intuition, etc., and bearing parts, etc. are replaced based on the above data after a suitable operating period, even if there is slight variation, the timing for parts replacement will be significantly missed. Nothing happened. In other words, parts that have hardly worn out have been replaced,
Or, even though a certain part had worn out so much that it was already time to replace it, there was little risk of a serious breakdown occurring if the machine continued to be operated.

However, as the winding speed of spinning winding machines increases as mentioned above, the degree of wear on moving parts such as bearings or drive motors varies greatly depending on each part, or there are special However, there were moving parts that were subject to significant wear and tear, making it impossible to perform proper maintenance by relying on conventional data or intuition based on the operator's experience.

A spindle motor 7 is connected to the base end of each bobbin holder 2, and the motor 7 actively rotates the bobbin holder 2. As the revolving turret 3 rotates, each bobbin holder 2 rotates. The position can be changed so that a full bobbin and an empty bobbin can be exchanged.

The weight of the lifting frame 6 is supported by a fluid cylinder (not shown), and the weight of the lifting frame 6 is supported by a fluid cylinder (not shown).

In this winding machine, in the same way as the known method,
The spun yarn Y is traversed by a traverse device 5 and wound onto a bobbin 8 which is actively rotating. A sensor is installed in this manner, and an analysis device 13 and a display device 14 for analyzing and displaying information from the sensor are connected.

That is, the bearings 15 and 16 before and after each bobbin holder 2, the spindle motor 7 of each bobbin holder, and the scroll cam roller 11.
Thermocouples 23 are provided in contact with the front and rear bearings 17, 18 and the drive motor 9, and the front and rear bearings 21, 22 of the Tatsuchi roller 4, respectively, and the tip of the lifting frame 6 has a vibration sensor. An acceleration sensor 24 is installed to detect the

The thermocouple 23 is installed so that its detection end contacts the outer housing of each bearing or the housing of each motor, and the acceleration sensor 24 is installed at the tip of the lifting frame 6 where the touch roller 4, scroll cam roller 11, and bobbin holder 2 are closest. It is installed.

A thermocouple 23 attached to the bearings 21 and 22 of the touch roller 4, a thermocouple 23 attached to the bearings 17 and 18 of the scroll cam roller 11, a thermocouple 23 attached to the drive motor 9, and an acceleration sensor Each output line 25 from 24 is connected to a controller 28 outside the machine via a multiplexer 26 and a converter 27 provided in the frame 1, and is connected to a thermoelectric wire attached to the bearings 15, 16 of each bobbin holder 2. The pair 23 and each output line 25 from the thermocouple 23 attached to the spindle motor 7 are connected to a multiplexer 29 provided in the revolving turret 3, a converter 31, and a slip ring 3 coaxial with the turret 3.
2 to a controller 28 outside the machine.

The multiplexers 26 and 29 receive the signal 33 from the controller 8 and convert the horizontal vibration signal 4a and the vertical vibration signal 24b of each thermocouple 23 and acceleration sensor 24 into serial signals,
31 is each thermocouple 23 converted into its serial
The temperature information and vibration information from the acceleration sensor 24 are converted into a current value that can be input to the controller 28 or a Fourier transformer 34, which will be described later.

As shown in the first figure, the slip ring 32 is mounted coaxially with the rotating shaft 35 of the revolving turret 3, and is attached to the bobbin holder 2 and the spindle motor 7.
Even if the turret rotates three times, each thermocouple 2
The output signal from 3 is outputted to the controller 28 without interruption.

Numeral 36 is a multiplexer which switches the output signal from the bobbin holder 2 side and the output signals from the touch roller 4, traverse device 5, and acceleration sensor 24 to produce a serial signal.

In addition, the controller 28 of each output signal 37 described above
The vibration information from the acceleration sensor 24 is Fourier-transformed and analyzed into each frequency component, and the analyzed information is sent to the microcomputer 3.
The controller 28 is also connected to the microcomputer 38, and the input temperature information and vibration information are sent to the microcomputer 3.
It can be displayed on CRT14 of 8.

That is, in the above example, both the Fourier transformer 34 and the microcomputer 38

For example, since the winding machine according to the present invention is configured as described above, during winding operation at high speed, each bobbin holder 2, touch roller 4, traverse device 5
Temperature information and vibration information of the frame 6 are always input in real time to the microcomputer 38 from each movable part, and each information is displayed on the CRT 14 in the following manner, for example.

That is, as shown in Figure 3, each detection position is displayed on the horizontal axis and the temperature information and vibration information of each detection position are displayed on the vertical axis as a bar graph on the CRT 14, and the vibration information is displayed on the CRT 14 as shown in Figure 4. The information analyzed for each frequency component by the Fourier transformer 34 can be displayed on the CRT 14 as is.

When displaying as shown in Figure 3, the same reference value or different reference value for each detection position is input into the microcomputer 38, and the reference value 41 is also displayed on the CRT 14. Then, the operator can instantly determine that the portion of the bearing or motor that exceeds the reference value 41 is overheating.

In the example shown in the third figure, the temperature of the seventh component from the left exceeds the reference value 41, indicating that this location requires maintenance.

In addition, when displayed as shown in the fourth figure, since the vibration information is divided into frequency components, the frequency component is located at the position B corresponding to the number of rotations of the bobbin holder 2.

In the above embodiment, the thermocouple 23 is a temperature sensor, and the acceleration sensor 24 is a vibration sensor.
Since both temperature and vibration information about the winding machine are monitored in real time using
