Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for processing a thread end of a bobbin that has been picked out.

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

As shown in FIG. 5, conventionally, this type of pick-up device has four slots in the middle of a transfer path 1 to an automatic winder (not shown).
At stations A to F installed around the rotary plate 2 which is intermittently rotated, pick-up is performed in sequence.

That is, the bobbin 4 placed in the tray 3 is punched and unwound by the unwinding roller 5 installed at station B, and then rotated by the rotating roller 6 installed at station C, thereby unwinding the yarn Y. It is lightly wound around the surface of yarn layer 7 and sent to the next station D.

Then, at station D, the mouse portion 9 and the slit 10 are rotated toward the unwinding side by the rotating roller 8.
The yarn end Y is sucked and held by a suction mouth 11 having a ) is inserted into the shaft hole from the top hole 14 of the bobbin core tube 13. In this state, the bobbin 4 is sent to the automatic winder via station F.

[Problems to be Solved by the Invention] By the way, the bobbin 4 that has been opened in this way is supplied to an automatic winder, and in each winding unit, the yarn end Y is blown up and captured by the suction pipe, and is rewound. It turns out.

However, during this blow-up, due to the fuzz between the thread Y being pulled out and the thread layer 7 of the bobbin 4, the thread is not completely unraveled and
There was a problem in that blow-up sometimes did not occur.

In addition, in the case of an automatic winder that is supplied with a bobbin with remaining yarn in addition to a full bobbin, the distance between the yarn layer 7 and the bobbin top hole 14 is large, so the free yarn length is large, and the yarn is inserted during transportation. The yarn end Y inserted through the top hole 14 will be pulled out, or even if it is not dragged out, the length of the yarn end Y inserted through the top hole 14 will be shortened, and the yarn end Y will be sucked into the suction pipe waiting above when blowing up. There was a problem that a catch error could occur.

In view of the above-mentioned circumstances, the present invention has been devised to provide a new thread end processing device for threading a bobbin into a state where blow-up errors and the like do not occur.

[Means for Solving the Problems] The present invention includes a rotating means for rotating a bobbin from which a thread end has been pulled out around its axis, and a rotating means for regulating the thread wound around the bobbin by the rotation below the bobbin hole. It is equipped with a guide member.

[Function] With the above configuration, the thread pulled out from the bobbin is wound around the core tube or the upper part of the thread layer of the bobbin, and after being cut, it is inserted into the top hole and brought into the open state.

C Example] Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 and 2 show an embodiment of a pick-up yarn end processing device according to the present invention, and are shown as being installed in a pick-up device that is substantially the same as a conventional pick-up device.

This device is comprised of a rotating means 21 for rotating the bobbin 4 around its axis, and a guide member 22 for regulating the thread Y wound around the bobbin 4 by the rotation below the bobbin top hole 14.

The rotating means 21 is provided at the station E of the pick-out device, and includes a roller 23 that contacts the side surface of the tray 3, and a roller 23 that contacts the side surface of the tray 3.
3 and a motor 24 for appropriately rotating the motor 3. That is, the bobbin 4 with the yarn end Y being suctioned by the suction mouth 25 is rotated a predetermined number of times together with the tray 3. Further, the rotation direction a of the bobbin 4 is the same direction as the winding direction of the yarn layer 7, in other words, the direction is such that the yarn is not unwound.

The suction mouth 25 is appropriately bent and extended from station D to E as in the conventional case.

The mouth portion 26 is formed to face the side of the bobbin 4 located at station D, and a slit 27 is formed continuously above or substantially horizontally from the mouth portion 26. .

In this embodiment, this suction mouse 25 is
As shown in FIG. 2, the slit 27 is formed to extend from the outside of the disk 2 to the inside via above the bobbin 4 of the station E.

The guide member 22 is formed of a horizontally cantilevered rod, and is formed to abut tangentially on the side surface of the upper end of the bobbin core tube 13 at the station E. The base end side of this guide member 22 is positioned between the slit 27 of the suction mouth 25 and the bobbin 4 at the station D. That is, the thread Y passing through the slit 27 while being attracted is engaged with the lower and outer sides of the guide member 22 and guided.

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

Next, the operation of this embodiment will be explained.

Bobbin 4 fed into the pick-out device and punched and unwound
At station D, the yarn end Y is suctioned by the mouse B26 of the suction mouth 25, and
7 and held upward. At this time, the thread Y is engaged with the lower side of the guide member 22 in the middle thereof.

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

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

After insertion, the bobbin 4 is moved to station F, during which the guide member 22 is removed from the thread Y. Therefore, the yarn Y pulled out from the yarn layer 7 is wound in the middle and inserted into the shaft hole 28 before being supplied to the automatic winder.

In the winding unit of the automatic winder, the inserted yarn end Y is blown up, and the continuously wound yarn Y is unwound and blown up.
In this way, since the rotating means 21 is provided at the station E and the guide member 22 is provided which engages the thread Y being sucked by the suction mouth 25, the excess thread Y is removed from the core tube. 1
3, and there is no occurrence of fluffing with the yarn layer 7. In other words, unwinding and
Blow-up mistakes are prevented.

In addition, this guide member 22 holds the thread Y wound around it until it is in contact with it, so that it does not unravel due to the suction force of the suction mouth 25, and the thread Y is not sucked into the shaft hole 28. The wound portion is not pulled together with the yarn end Y when the yarn is wound.

That is, the guide member 22 has the function of guiding the yarn Y so that it is wound around the core tube 13, and also regulating the wound yarn Y so that it does not unravel.

Further, in FIG. 1, a full bobbin 4 is shown, but even a bobbin with remaining yarn can be wound in the same manner.

In this case, as shown in FIGS. 3 and 4, the drawn-out yarn Y is wound several times between the yarn layer 32 of the bobbin 31 with remaining yarn and the upper end 33 of the core tube 13, and then further wound around the upper end 33 of the core tube 13. The winding is made at section 33. Therefore, the sky hole 14
The thread Y up to is all wound around the core tube 13,
There are no extra tricks during transportation, and catch errors in the winding unit are prevented.

In this embodiment, the yarn Y is wound around the core tube 13, but even if a guide member 22 is formed to guide the yarn Y so that it is wound around the upper part of the yarn layer (chess part), it will not become oval.

It should be noted that yarn processing can be performed in the same manner as described above also in a thread pulling device in which the suction mouth 25 is provided at station E.

[Effects of the Invention] In summary, according to the present invention, the following excellent effects are achieved.

The present invention is equipped with a rotating means for rotating the bobbin from which the thread end has been pulled out around its axis, and a guide member that restricts the thread wound around the bobbin by the rotation below the bobbin hole, so that the thread end is not attached to the bobbin. It is possible to unwind the shaft after it has been wound several times and inserted into the shaft hole, which prevents mistakes in unwinding and blowing up in the automatic winder in the next process.
