The winding unit 102 winds the yarn Y wound around the spinning bobbin 113 around the paper tube B to form a larger package P. On the delivery side of the winding unit 102, a spinning bobbin 113 is automatically supplied from the continuous automatic bobbin supplying device 6 of FIG. 1 installed at the end of the machine base 101 to connect threads, remove thread defects, etc. Is automatically performed by the control circuit 114. Incidentally, 125 is a slab catcher, and 126 is a yarn splicing device.

In FIG. 3, a first temperature sensor 33, a second temperature sensor 34, and a small camera 35 are installed in this order from the top at the portion of the doffing device 106 facing the package P, and are connected to the computing unit 3 of FIG. Has been done. The first temperature sensor 33 is installed toward the bobbin supporting portion 31 of the cradle arm 110, and the second temperature sensor 34 is the rotating shaft portion 32 of the drum 129.
And detects the temperature of a bearing (not shown) of the relevant part. A non-contact type infrared heat sensing sensor or the like is used for both the temperature sensors 33 and 34. The small camera 35 is installed toward the tensor roller 127a of the tensor 127, and the tensor roller 127a is provided with a mark 37 such as a color mark for confirming the presence or absence of rotation. The small camera 35 detects the presence / absence of rotation of the roller 127a by the mark 37.

An upper limit value 36 is set in advance in the control device in accordance with the relationship between the temperature during operation and the service life obtained from experience in use, experiments, etc. When the upper limit value 36 is exceeded (t1), as shown in FIG. A display for instructing maintenance is displayed on the display device 5. Therefore, maintenance can be predicted. Further, when the failure occurs at once, the failure can be automatically detected.

Further, these processed data are sent to the central control unit 4 to be accumulated, and are also displayed and output to be used for further analysis of the maintenance information.

In the above embodiment, the case where the bearing temperature and the presence / absence of rotation of the roller are detected as the maintenance information has been described, but the present invention is not limited to these, and for example, a specific member. It is possible to apply it as long as it is maintenance information such as detecting the operation of.
