Referring to the operating state of the spindle drive (A) of the present invention configured as described above are as follows.

In other words, the spindle drive device (A) of the present invention is installed on the front side of the main body (6) of the winder in parallel with the real winding guide device (B) and left and right, respectively, the lower part bobbin falling from the spindle drive device (A) in the lower portion When the guide tube 50 rotates to be discharged when discharged, and the dropper 60 which detects the trimming while guiding the thread supplied from the yarn cone to the rotary table of the tube tube 50 is installed, the spindle drive device A The thread collecting table 70 is mounted on the outside to supply the thread of the bobbin bobbin to the threading actuator having the tip of the spindle 2 so that the space is utilized so as not to interfere with each other so that the bite is made. .

In the above state, the spindle drive device A is wound as shown in Figs. 2 and 4 by the completion of winding of the thread in the bobbin, and the spindle drive device A rotates from the thread winding guide device B to the other side. As the spindle 4 retracts through the cylinder 14, the full bobbin falls down and rests on the mandrel plate 50, which is waiting at the bottom, while a new bobbin is supplied between the spindle 2 and the tailspin 4. This is done.

Subsequently, the cylinder of the threaded bobbin in the discharged state is seated on the pipe plate 50 so that the thread is snapped to the threading actuator of the spindle 2 by the thread collecting rod 70 rotating from the outside. 14) The tail spindle 4 advances the tail spindle 4 to cut the thread of the dropped bobbin while the threading actuator of the spindle 2 bites the thread, so that the spindle drive A receives a new bobbin and receives the thread winding guide device. It is ready for transfer to (B).

Before turning to the other thread winding guide device B in the preparation step in which the new bobbin is mounted on the spindle drive A, the cylinder 14 of the present invention reverses the tail spindles 4 back slightly.

After the thread is gradually wound on the bobbin, as the winding diameter of the bobbin increases in a full range, the spindle drive A naturally moves away from the guide drum 18 and the rotating body 30 moves in reverse to guide the groove 28. At the time of reaching the position substantially perpendicular to the axis), the belt 42 coupled to the linked lever 36 descends and senses the thread length wound on the bobbin according to the rotation of the encoder 44 axis. ) And the rotation of the guide drum 18 is stopped.

The spring 40, which is connected to the spindle drive A to the lever 36, is again tensioned when the pivot 30 in the state where the winding operation is stopped is perpendicular to the guide groove 28. By applying the inverted and linked rotating body 30 to be rotated so as to move completely back along the guide groove 28, the operation of the spindle drive A is completed. After that, the full bobbin drops and the new bobbin is dropped. All operations made by switching to the preparatory stage of supplying are performed smoothly without operation errors.

Therefore, the spindle drive device (A) of the present invention is rotated with the thread winding guide device (B) on the other side to be controlled to form the shape of the thread cleanly at a constant pressure during the winding operation, and with other devices sequentially linked and operated. The structure can be simplified by utilizing a wide space for smooth operation without interference, and since the spindle drive (A) is rotated to wind the bobbin from the actual winding guide device (B), various sizes of cone bobbins can be used. It would be.
