Description

[Detailed Description of the Invention] The present invention has been developed by approaching the bobbin holder of the above-mentioned cradle arm for the purpose of punch winding a punch winding device, in particular, to be able to punch wind continuously fed yarn without slack. The present invention is characterized in that a yarn end holding member is provided at this position, which also functions as a suction device that can suction the yarn end before punch winding is started, and a cutting device that can appropriately cut the suctioned yarn end.

Yarn spun by an air spinning device is continuously fed out, so when winding the spun yarn around an empty bobbin, the yarn fed out becomes slack during the winding operation. This makes it difficult to perform reliable winding.

Therefore, the device of the present invention makes it possible to wind the yarn end around an empty bobbin without causing this slack.

An example of implementation of the device of the present invention will be described below with reference to the drawings.

Reference numeral 1 designates a cradle arm consisting of a pair of arms rotatably supported by a shaft 2 in the direction of the arrow 3, each of which has a bobbin holder 4 rotatably mounted on the same center. It is positioned on the line and supported by the shaft 5.

The bobbin holder 4 has a dish shape, and a groove 6 is formed on the periphery of one bobbin holder, and a thread retaining water 7 is formed on the side wall surface of the groove 6.
is provided so as to protrude across the groove 6.

A bobbin 8 is supported between the pair of bobbin holders 4, 4.

A drive roller 9 is supported by a support member 10, and a yarn end holding member 11 is provided at the top of the support member 100 close to the bobbin 8.

Reference numeral 12 denotes a yarn end suction device for the yarn end holding member 11, which consists of a duct 12 connected to a pressure reducing device (not shown), and a suction port 13 is provided in the sliding plate 14 at a position facing the groove 6 of the bobbin holder 4. It's crawling.

The sliding plate 14 has a ventilation hole 15 provided on the front side of the duct 12.
It is slidably supported by a guide groove provided on the front surface of the duct 12.

When the suction port 13 and the ventilation port 15 match, the yarn end is sucked into the duct 12 from the outside, and the suction port 13 is connected to the duct 112.
0 ventilation hole 15 when the outside air duct 12
Inhale inside.

If the position of the suction port 13 is shifted from the ventilation port 15 by sliding the plate 14, the suction is stopped, and at the same time, the edge 15' of the ventilation port 15 and the edge of the suction port 13 of the sliding plate 14 are 1
3' acts as a cutter 19.

Next, the operation of the device of the present invention will be explained.

When the bobbin is fully wound with thread, the cradle arm 1 turns in the direction of arrow 3 and is doffed by known means, and the empty bobbin 8 is placed in the bobbin holders 4 and 4 of the cradle arm 1.
installed in between.

During this time, the yarn end is sucked into the duct 12 from the suction port 13 of the yarn end holding member 11.

When the empty bobbin 8 is attached to the bobbin holder 4, the thread end 16, which is suctioned and held by the thread end holding member 11, is guided into the groove 6 of the bobbin holder 4 by an appropriate thread guide tool 11.

The thread guide tool 17 is a thin rod-shaped body, a wire, etc. with a hook 18 formed at its tip, and when the thread guide tool 17 is held in hand, the thread end 16 being sucked into the suction port 13 of the thread end holding member 11 is held. is engaged with the hook 18 and the thread end is guided into the groove 6 of the bobbin holder 4.

As a result, the yarn that is connected between the spinning side and the yarn end holding member 11 engages the yarn locking pawl 7 of the bobbin holder 4 in the middle, so that one side is on the spinning side and the other is on the yarn end holding member 11. It exhibits a state of being extended toward the thread holding member side.

At this time, since the bobbin holder 4 is rotating, the groove 6
The thread end 16 is caught on the thread locking piece 7 that protrudes inward, and the 2
When the suction port 13 has been wrapped around the groove three times, the suction port 13 is slid sideways together with the sliding plate 14, and the edge 13' of the suction port 13 and the edge 15' of the ventilation port 15 provided on the sliding plate 14 are The thread being sucked into the duct 12 between the threads is cut.

The above-mentioned guiding of the thread into the groove 6 by the thread guide device 17 and the sliding of the suction port 13 are continuous operations, and two to three threads are placed in the groove 6.
Do it quickly while waiting for the turn.

Next, the thread wound around the groove 6 is guided to the end of the bobbin by the thread guide device 17, and after punch winding is performed, a normal traverse is started to form a thread layer on the bobbin 8.

According to the device of the present invention, as described above, since the steam yarn end holding member is provided close to the empty bobbin and serves as a suction device and a cutting device for appropriately cutting the suctioned yarn ends, while the empty bobbin is being attached, the steam yarn end holding member is provided. The yarn end that is continuously spun can be held without slackening, and the yarn end can be cut immediately after winding around the bobbin is started.

The sliding plate of the present invention can close the vent at the same time as cutting the thread under suction, and the sliding plate seals the vent by the suction force of the duct.

Therefore, it is possible to prevent the suction force from decreasing in other weights, and it is possible to reliably perform the punch winding operation for each weight.

Furthermore, since the sliding plate cuts the yarn by sliding, it has the advantage of high cutting ability.
