。(Prior Art) In an open-end spinning machine equipped with a large number of take-out units that heat and continuously draw out the fibers guided to the eastern part of the inner heel of the rotor, the rotor's rotating shaft ( The shaft is rotated by applying pressure to the spindle. This belt drive system has the disadvantage that the transmission efficiency between the bell 1 and the drive J pulley, guide pulley, or spindle is poor and power consumption per heel is large. Furthermore, since the radial load moves on the bearing that supports the rotor spindle, there is a problem that the bearing wears out over time. These problems become more noticeable when the rotor rotates at an extremely high speed.

提案されている。To solve this problem, Japanese Patent Publication No. 51-13778 published on May 4, 1978 proposes a device in which the spindle of each rotor is directly connected to a motor to drive it. Also, ring spinning other than open end spinning 1m? 7 also proposes driving the spindle by directly connecting it to a motor.

題がある。(Problem to be solved by the invention) However, in the conventional device described above, even if the bearing is damaged due to the bearing load of the spindle due to high speed rotation, the operation continues without noticing the damage, and it is difficult to avoid overload. This causes the recoil to break 10, and there is an inconvenience that in order to replace the spindle, the entire motor including the coil portion must be replaced. Furthermore, in Japanese Patent Publication No. 58-9169 published on February 19, 1988, a device was proposed that reliably lubricates the bearings of a rotor rotating at high speed for a long time. If operation is continued in a state where the parts are worn and damaged, the coils will be damaged, and there is a problem in that the cost of replacement becomes high as in the conventional device.

The detection signal No. 13 is sent to the arithmetic unit, and the arithmetic unit constantly compares the detection signal with a predetermined reference value. If the detection signal exceeds a predetermined reference value, it is determined that the spindle is abnormal and an abnormality signal is output.
Based on that signal, single shogun! Power supply to the I7J device is stopped. Therefore, an abnormality in the spindle can be reliably detected before it causes damage to the coil, and only the spindle can be replaced at that point.

Electric power is supplied to the single spindle drive device 3 of each spinning unit 1 from a power source 4 via an inverter 5 and a drive device 6. The detection part 12a of the thermal lightning thermometer 12 disposed in each single spindle drive device 3 always detects the temperature of the bearing 93,
Electricity (ffi number) is sent from the thermal N thermometer 12 to the calculation device 13.The calculation device 13 deduces the temperature If of the bearing 9a based on the detection signal from the thermal lightning thermometer 12,
Compare with the reference temperature corresponding to the spindle abnormality. In the calculation step 13, when the temperature detected by the thermocouple thermometer 12 exceeds the temperature t, it is determined that there is an abnormality in the spindle and outputs an abnormal signal to the drive device 6, and the drive device 6 operates to supply electricity from the inverter 5. The electric power supplied to the machine is cut off, and the spinning unit 1 stops driving. The arithmetic device 13 outputs an abnormal signal to the drive device 6 and at the same time outputs the abnormal signal to the monitor device 1.

The power supply to each single spindle drive device 3 is controlled using a drive device built into the unit. That is, in the device of this embodiment, when the spindle is abnormal, the arithmetic unit 13
A signal output from the inverter 5 is inputted to the inverter 5, and a drive device within the inverter 5 is activated based on the signal, and the supply of power to the single spindle drive device 3 is stopped. Therefore,
In the apparatus of this embodiment, as in the apparatus of the second embodiment, during spindle replacement work due to spindle abnormality,
By simply stopping the single spindle drive device 3 of the spinning unit 1, the other spinning units 1 can continue spinning. Furthermore, when replacing the spindle 7 with a new one, it is usually preferable to perform a break-in operation of the spindle, but in this device, since the inverter 5 is installed independently for each spinning unit 1, other The spindle can be run-in without affecting the spinning unit 1.
