Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for treating a yarn end of a bobbin that has been ejected.

[Prior Art] Generally, an automatic winder for rewinding a yarn is equipped with a yarn end feeding device for pulling out the yarn end of a bobbin to be supplied.

As shown in FIG. 5, conventionally, this type of tapping device is provided in the middle of a transfer path 1 to an automatic winder (not shown),
In stations A to F installed around the rotary plate 2 which is rotated intermittently, the lead-out is sequentially performed.

That is, the bobbin 4 inserted in the tray 3 is unbunched by the unwinding roller 5 provided in the station B, and then rotated by the rotating roller 6 provided in the station C, so that the yarn Y It is lightly wound around the surface of the yarn layer 7 and sent to the next station D.

Then, at station D, the yarn end Y is sucked and held by the suction mouth 11 having the mouth portion 9 and the slit 10 while being rotated to the unwinding side by the rotating roller 8, and at the next station E, the yarn YGF cutter 12
Is cut into an appropriate length by the, and is inserted into the shaft hole from the top hole 14 of the bobbin core tube 13 by a suction pipe (not shown) provided below. In this state, the bobbin 4 is sent to the automatic winder via the station F.

[Problems to be Solved by the Invention] By the way, the bobbin 4 thus dispensed is supplied to the automatic winder, and in each winding unit, the yarn end Y is blown up by the suction pipe to be caught and rewound. It will be.

However, at the time of this blow-up, the fluff between the drawn yarn Y and the yarn layer 7 of the bobbin 4 sufficiently unwinds the yarn.
There was a problem that the blow-up might not be done.

In addition, in the case of an automatic winder in which a bobbin with residual thread is supplied in addition to the groove bobbin, the free thread length is large because the distance between the thread layer 7 and the bobbin top hole 14 is large, and it is inserted during transportation Even if the thread end Y that has been drawn is dragged out, or even if it is not dragged out, the length of the thread end Y that is inserted from the top hole 14 will be shortened, and it will not be sucked into the suction pipe that stands up at the time of blowing up. There was a problem of catching mistakes.

In view of the above circumstances, the present invention has been devised to newly provide a yarn end yarn end treating device that brings a bobbin to be led out into a state in which a mistake such as blowing up does not occur.

[Means for Solving the Problems] The present invention relates to a yarn drawing means for drawing a yarn from a yarn layer, a rotating means for rotating a bobbin drawn from the yarn layer around its axis, and a yarn. And a guide member for guiding the yarn to the upper portion of the bobbin rotated by the rotating means and winding the yarn around the upper end portion of the core tube.

[Operation] With the above configuration, the rotating means rotates the bobbin from which the thread has been drawn out by the thread drawing means, around its axis.
The guide member engages the drawn-out thread, guides the thread to the upper part of the rotating bobbin, and winds the thread around the upper end of the core tube.

EXAMPLES Examples of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 and FIG. 2 show an embodiment of an outlet yarn end treating apparatus according to the present invention, and are shown as being provided in an outlet device substantially similar to the conventional one.

This device includes rotating means 21 for rotating the bobbin 4 about its axis, and a guide member 22 for restricting the yarn Y wound around the bobbin 4 below the bobbin top hole 14 by the rotation.
It consists of and.

The rotating means 21 is provided at the station E of the feeding device, and is formed by a roller 23 that comes into contact with the side surface of the tray 3 and a motor 24 that appropriately rotates the roller 23. That is, the bobbin 4 in a state in which the thread (thread end) 7 from the thread layer 7 is sucked by the suction mouth 25 which is a thread drawing means.
Are rotated together with the tray 3 a predetermined number of times. The rotation direction a of the bobbin 4 is the same as the winding direction of the yarn layer 7, in other words, the direction in which the yarn is not unwound.

The suction mouth 25 is appropriately bent and extended from the stations D to E as in the conventional case. The mouse portion 26 is formed so as to face the side portion of the bobbin 4 located at the station D, and
A slit 27 is formed continuously from 26 upward or substantially horizontally.

In this embodiment, the suction mouse 25 is the second
As shown in the figure, the slit 27 is formed so as to extend from the outer side of the disc 2 to the inner side via the upper side of the bobbin 4 of the station E.

The guide member 22 is composed of a horizontally supported cantilevered rod body,
At the station E, on the upper end side surface of the bobbin core tube 13,
It is formed so as to abut tangentially. The base end side of the guide member 22 is located at the winding of the slit 27 of the suction mouth 25 and the bobbin 4 at the station D. That is, the yarn Y passing through the slit 27 while being sucked is engaged and guided below and outside the guide member 22.

In addition, the station E is provided with a suction pipe 29 for sucking the yarn Y cut by the cutter 6 from the top hole 14 to the shaft hole 28 of the core tube 13.

Next, the operation of this embodiment will be described.

Bobbin 4 unwound and punched in the dispensing device
At the station D, the yarn end Y is sucked by the mouth portion 26 of the suction mouth 25, pulled out along the slit 27, and held upward. At this time, the yarn Y is
During this process, the lower side of the guide member 22 is engaged.

Then, at the next station E, the bobbin 4 is rotated by the rotating means 21. This is the yarn Y being sucked
While being guided to the upper end of the core tube 13 by the guide member 22, it is wound around this several times.

After the winding is completed, the cutter 12 cuts the yarn Y above it. The cut thread end Y is a suction pipe.
It is sucked by 29 and inserted into the shaft hole 28 from the top hole 14.

After the insertion, the bobbin 4 is moved to the station F, and the guide member 22 is disengaged from the yarn Y in the process. Therefore, the yarn Y drawn from the yarn layer 7 is supplied to the automatic winder in a state in which the yarn Y is wound in the middle and inserted into the shaft hole 28.

Then, in the winding unit of the automatic winder, the inserted yarn end Y is blown up, and the yarn Y that has been continuously wound is unwound and blown up.
It is caught by the suction pipe.

As described above, since the rotating means 21 is provided in the station E and the guide member 22 that engages with the yarn Y sucked by the suction mouth 25 is provided, the extra yarn Y can be wound around the core tube 13, No fluffing with the layer 7 occurs. That is, unwinding and blowing mistakes in the automatic winder are prevented.

Further, since the guide member 22 holds the yarn Y wound by rotation as it is at the abutting portion, it is not loosened by the suction force of the suction mouth 25. In addition, the wound portion is not pulled together with the yarn end Y when sucked into the shaft hole 28.

That is, the guide member 22 has a function of guiding the yarn Y to be wound around the core tube 13 and a function of restricting the wound yarn Y from being unwound.

Further, although the groove bobbin 4 is illustrated in FIG. 1, the bobbin with the residual thread is similarly wound.

In this case, as shown in FIGS. 3 and 4, the pulled-out yarn Y is the yarn layer 32 of the bobbin 31 with residual yarn and the upper end portion of the core tube 13.
It is wound several times with respect to 33, and further wound at the upper end 33. Therefore, all the yarns Y up to the top hole 14 are wound around the core tube 13 so that there is no yarn dropout during conveyance and catch mistakes in the winding unit are prevented.

The yarn processing can be performed in the same manner as above even in the case of the picking device in which the suction mouth 25 is provided in the station E.

[Effects of the Invention] In short, according to the present invention, the yarn drawn from the yarn layer can be ejected in a state of being wound around the upper end portion of the core tube of the bobbin by a predetermined amount, and unwinding in the bobbin yarn rewinding step
It has the excellent effect of preventing blow-up mistakes.
