損を生ずる欠点があった。(Problems to be solved by the invention) In the conventional high-speed winding machine shown in FIG. 4, the peripheral speed of the yarn is 8,000 m /
The bobbin shaft rotation speed has reached 20,000 times / minute. If the bobbin collapses while the bobbin is rotating at such a high speed, the weight balance around the bobbin shafts 3 and 3'is disrupted and the bobbin shafts 3 and 3'are supported by a cantilever. Therefore, the bobbin shafts 3 and 3'has a drawback that they are subjected to a large bending force and the supporting force of the bobbin bearing is exceeded, resulting in damage to the bobbin shaft, the bearing and peripheral parts.

決のための手段とするものである。Therefore, according to the present invention, an extension shaft is provided on the center line of the bobbin shaft tip of a high-speed winder, and a bearing device that is movable in the axial direction is provided on the extension shaft. The inner diameter of the bearing is larger than the outer diameter of the extension shaft, and the clearance is set so that it does not come into contact even when considering the runout of the bobbin shaft during normal operation. At times, the bearing device is configured to support the extension shaft, which serves as means for solving the problem.

The bearing is designed to be a holding shaft, the inner diameter of the bearing is larger than the outer diameter of the extension shaft, and the clearance is set so that it will not come into contact even when considering the runout of the bobbin shaft during normal operation.
The bearing is in a position to support the bobbin shaft during operation, but it moves in the direction away from the bobbin shaft until the bobbin is fully wound and the turret is turned until the next bobbin comes to the predetermined position. Stand by at a position that will not interfere with various tasks.

減少を図ることができる。On the other hand, when the bobbin of the winder winds the yarn at high speed, if an unbalance occurs around the bobbin shaft due to collapse of the winding balls, the bearing placed in non-contact supports the tip of the bobbin shaft. The displacement of the bobbin shaft can be suppressed, damage around the bobbin shaft can be prevented, and the bobbin shaft can be kept small. Further, during normal operation, the extension shaft at the end of the bobbin shaft and the bearing are not in contact with each other, so that it is not necessary to use a high-speed lubricating device for this bearing, and the cost can be reduced.

触であり、球軸受16は回転しない。To explain the operation, FIG. 1 shows the positions of the respective parts when the bobbin winds the yarn at a high speed. The turret 2 is kept in a predetermined position by the pin of the pneumatic cylinder 25, and the ball bearing 16 is in a position straddling the extension shaft 15. However, the shaft center of the ball bearing 16 and the shaft center of the extension shaft 15 are on the same center line, and the inner diameter d 2 of the ball bearing 16 is larger than the outer diameter d 1 of the extension shaft 15, so that the bobbin shaft 3 swings during normal operation. In consideration of the above, the gap is set so that the ball bearing 16 does not come into contact with each other, and therefore the ball bearing 16 does not rotate during normal operation.

故防止の役割を終った後取替えることとする。This high-speed winder is so fast as to reach a maximum yarn speed of 8,000 m / min and a maximum bobbin rotation speed of 20,000 rpm, so if an unbalance around the bobbin occurs due to a collapse of the yarn ball, you should use a ball bearing. If there is no support for 16, the bobbin shaft 3 is supported only by the bearing on the side of the turret 2, so the imbalance expands all at once, leading to major damage around the bobbin shaft. However, because of the support of the ball bearing 16, the deviation of the bobbin shaft 3 due to the imbalance is suppressed to the size of the gap between the extension shaft 15 and the ball bearing 16, and large damage is prevented. Also, since the ball bearing 16 is instantly accelerated to a high rotation speed, there is a high possibility that seizure or burnout will occur, but this mechanism is a precaution and should be replaced after it has finished its role of preventing accidents. .

す。When the bobbin B is full in normal operation, compressed air enters the pneumatic cylinder 20, the bearing holder 18 moves leftward, and the ball bearing 16 comes out of the extension shaft 15. Next, the touch roll 13 is raised, the pin of the pneumatic cylinder 25 that has stopped the turret 2 is removed, the electric motor 4 is rotated, and the turret 2 is slowly rotated to switch bobbins B and B '. Shortly before the turret 2 has finished rotating 180 °, the limit switch 24 is actuated by the cam 33 to further reduce the rotation speed of the electric motor 4, and the pin of the pneumatic cylinder 25 is pushed out to stop the turret 2 at a predetermined position. Next, the rotation of the empty bobbin B'is increased, the touch roll 13 is lowered to cut the thread, and switching is performed. Next, the bearing holder 18 is replaced by the pneumatic cylinder 20.
Is pushed to the right by and the ball bearing 16 is located on the shaft 15.
The full bobbin is located at the positions 3'and 31 ', the rotation of the bobbin shaft 3 is stopped, and the bobbin is taken out from between the legs 29 of the abutment.
