Bobbin holder of winding machine

The present invention relates to a bobbin holder of a winding machine, and more particularly, when the bobbin rotates at a high speed by receiving a driving force generated from the power transmission device of the winding machine, an eccentric rotation is generated by the centrifugal force due to the deviation of the concentricity of the bobbin. Bobbins of one winding machine, to prevent shorting of the yarn while winding the yarn to the bobbin, to facilitate the replacement of the finished bobbin, and to selectively use bobbins of different heights. Relates to a holder.

As is generally known, a bobbin is a winding of a yarn which is a high speed and is fed as a raw material of a fabric by receiving a driving force of a power transmission device disposed at an appropriate position of a winding machine, through a belt.

1 is a configuration diagram showing an example of a general winding machine, Figure 2 is a cross-sectional view showing a conventional bobbin holder in detail.

As shown in the figure, a plurality of bobbin holders 20 are provided in the proper place of the main body 10 of the winding machine, and the yarn 30 is disposed below the main body 10.

A plurality of rollers and tensioning devices are disposed on elements of a path from the yarn 30 to the bobbin holder 20 to prevent shorting of the yarn 30 supplied toward the bobbin holder 20.

The bobbin holder 20 is a support portion in which a rotating part 22 is arranged below the bobbin holder 20, and an elastic member 24 is placed on the upper side of the bobbin holder 20 that coincides with the central axis of the rotating part 22. 23 is built up.

As shown in FIG. 3, the pivoting part 22 penetrates perpendicularly to the bobbin holder 20 disposed below, and includes a cylinder 22a in which an appropriate amount of oil is contained, and a lower end of the cylinder 22a. Is supported by the bearing portion 22c provided on the inside of the upper side is supported by the bearing (22d), but the outer peripheral surface of the rotating shaft 22b having an oil passage (22b '), and the upper end of the rotating shaft 22b is press-fitted It consists of the rotating member 22e which seals the upper side of the said cylinder 22a, and the cushion member 22f fitted in the upper side of the said rotating member 22e.

And, the upper side of the support 23 is provided with a lever 25 for compressing the elastic member 24 to raise and lower the support 23, the lower end is provided with a support member (23a).

On the other hand, the bobbin 27 is fitted above the rotating member 22e of the rotating part 22 and below the supporting member 25 of the supporting part 23.

That is, the driving force generated while driving the main body 10 of the winding machine is transmitted to a belt (not shown) by a power transmission device (not shown), and the power transmitted to the belt is rotated by the belt and the rotating part 22. Induces rotational force at.

As described above, when the rotating member 22e in which the rotating shaft 22b is pressurized is rotated by the rotating force transmitted to the rotating unit 22, and the rotating shaft 22b is rotated by the rotation of the rotating member 22e. The oil contained therein is lubricated by repeating the operation of raising and lowering along the oil passage 22b 'formed on the rotation shaft 22b.

Accordingly, the lower end of the bobbin 27 is rotated by receiving the power of the belt directly through the rotating member 22e, and the upper end thereof is coupled to be idling with respect to the support member 23a provided on the support 23 side. It is to be idle, the yarn (30) to be supplied is wound (권).

However, the following problems occur in the bobbin holder of such a general winding machine.

That is, the bobbin 27 is supplied to the rotating member 22e and the support member 23a of the bobbin holder 20 while being supplied with the rotational force of the belt applied to the rotating part 22 side to rotate at high speed. In the winding, the upper side of the bobbin 27 fitted to the tapered support member 23a is rotated out of the support member 23a by the rotational force generated while the rotation member 22e rotates to generate a centrifugal force.

Therefore, the centrifugal force generated from the upper side of the bobbin 27 is a factor that causes the bobbin to shake left and right on the basis of concentricity, that is, the vertical center line, and the fiber yarn is shorted when winding the thin fiber yarn by the shake. It became a factor.

At this time, the cushion member 22f supporting the lower end of the bobbin 27 in a state of being fitted above the rotating member 22e and rotating at high speed together with the rotating member 22e is subjected to the centrifugal force generated by the rotating member 22e. It extends outwards, thereby increasing the factor causing tremor on the upper side of the bobbin 27.

In addition, the bobbin is mainly made of aluminum, the inner diameter or outer diameter is not always uniformly produced during the manufacturing process, when the thickness and concentricity is slightly shifted or eccentrically used, the above-mentioned problems are more weighted. It is pointed out as a problem.

On the other hand, since the rotating part 22 requires a plurality of parts such as the rotating shaft 22b and the bearing part 22c in which the rotating member 22e and the oil flow path 22b 'are formed, the manufacturing process of the bobbin holder is difficult and the manufacturing cost In addition to being a factor to increase, the lower end portion of the rotating shaft 22b is in surface contact with the bearing portion 22c, and the long-term use due to the moistened structure causes wear and shortens the service life.

In addition, when the winding of the thread is completed on the bobbin 27, the bobbin is separated, and replaces the new bobbin, in this case, as shown by the one-point arrow of Figure 2, by operating the lever 25 with one hand upwards, the support ( 23) after lifting, the pivot member 26 'provided at the lower end thereof is separated from the upper end of the bobbin 27, and the support state of the bobbin 27 is released and at the same time the yarn is wound with the other hand. There is also the troublesome problem of separating (27).

The present invention is not limited thereto, and the rotating member 26 'supporting the upper side of the bobbin 27 has a height H at which the elastic member 24 holding the rotating member 26' downwardly can be compressed. Since it has almost the same height as), there is another problem that can not be used to replace the bobbin 27 having a different height.

Therefore, the technical problem to be achieved by the present invention, that is, the first object of the present invention is devised in view of the problems of the bobbin holder of the winding machine as described above, the driving force generated in the power transmission device of the winding machine When the bobbin is rotated at high speed, the concentricity of the bobbin is shifted and the eccentric rotation caused by the centrifugal force is prevented. To provide.

A second object of the present invention is to provide a bobbin holder of a winding machine that easily replaces a bobbin in which yarn winding is completed with a new bobbin.

It is a third object of the present invention to provide a bobbin holder of a winding machine which enlarges the use width of a bobbin holder by selectively using bobbins having different heights.

A fourth object of the present invention is to provide a bobbin holder of a winding machine, which simplifies the manufacturing process by simplifying the number of parts of a rotating part that transmits rotational force to the bobbin, and thus lowers the manufacturing cost.
