Description

[Detailed Description of the Invention] The present invention includes a yarn winding device, in particular, a plurality of spinning units that are integrated with a spinning device and continuously wind up the yarn spun by the spinning device.
In a yarn winding device in which a yarn splicing cart having knots is moved, a yarn storage device that suctions and stores spun yarn that is being continuously spun while the yarn splicing device is in operation by cutting the yarn or detecting a slab. By providing this between the spinning device and the winding device of the spinning unit, the purpose is to shorten the time from the end of the yarn splicing operation to the start of the yarn splicing truck.

Conventionally, a yarn winding device performs yarn splicing using a yarn splicing cart that moves the front surface of parallel spinning units.
The knotter is located on the side of the splicing device, and accordingly, a yarn storage device for suctioning and storing the yarn spun until the yarn splicing operation is completed is provided on the splicing cart. For this reason, even after the knotter ties the yarn and the yarn tying is completed, the yarn splicing cart must not be moved unless the yarn in the yarn storage device is completely out of the yarn storage device and positioned on the normal winding path. I couldn't. As a result, the yarn splicing cart was needlessly stopped for about 10 to 45 seconds until the stored yarn came out of the yarn storage device, which was not desirable in terms of work efficiency.

Therefore, in the present invention, once the yarn tying by the knotter is completed, the yarn accumulating device is passed through the yarn on the spinning unit side so that the yarn splicing cart can be moved even if the yarn is accumulated in the yarn accumulating device. The above drawbacks have been improved by providing them along the path.

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

One unit is a spinning device 1 such as an air spinning device, and a plurality of spinning/winding units 3 each having a spun yarn winding device 2 are arranged in parallel, and the front surface thereof is connected to a guide rail 4. The yarn splicing cart 5 is now able to travel.

Further, a shaft 35 of a solenoid 34 is engaged with the middle of the protruding rod 33, and the protruding rod 33 is swung when the solenoid 34 is activated. The solenoid 34 is activated by thread trimming sensing by a thread trimming sensing member (not shown).

The spinning side yarn end suction arm 52 has a tip end configured such that it can be inserted into the casing of the spinning device 2 when rotating in the clockwise direction in FIG. A thread guide groove 54 is provided on the side. A cam 55 is provided at the top of the package cage side yarn end suction arm 53. The cam 55 contacts the cam follower 28 of the cam plate 26 when the suction arm 53 rotates,
The cam plate 26 is rotated by the rotation of the suction arm 53.
It is constructed so that it can be rotated.

A package drive roller 56 is supported at the tip of an arm 58 that is swingably supported on a shaft 57.
When the arm 58 swings, it comes into contact with the package 6. 5
9 is Notusa.

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

Under normal conditions, the yarn 9 spun by the spinning device 1 such as an air spinning device passes through the rollers 10, the slab catcher 12, and the traverse guide 13 before being wound up into the package cage 6. 12 detects a slab or the like and cuts the yarn, the yarn end on the spinning side is transferred to the yarn storage device 1.
The yarn is sucked into the yarn storage device 11 from the yarn suction port 11a of No. 1, and at the same time receives a yarn breakage signal, the solenoid 34
is activated and the shaft 35 is projected. Therefore, the protruding rod 3 is reciprocated up and down by the constantly rotating disk 32.
3, the lower end is moved to the left in FIG. As a result, the protruding rod 33 moves downwardly when the supporting plate 20
The support plate 20 is rotated clockwise around the shaft 19, and the package pressing plate 18 is pushed between the friction roller 14 and the package 6 to hold the package 6 at the position indicated by the dashed line 6a. At the same time, the crank 24 also swings, and the lid 25 of the spinning device 1
Open. At this time, the protrusion 29 of the support plate 20 and the notch 30 of the cam plate 26 engage, and the cam plate 26 assumes the position indicated by the two-dot chain line.
3 rises, the support plate 20 also maintains the position indicated by the two-dot chain line. In this state, a thread breakage indicator (not shown) is displayed and the unit in which the thread breakage has occurred stops winding.

There, the cart 5 moves and stops in front of the thread cutting and spinning unit by normal means, and the package operating lever 51 rotates and comes into contact with the shoe 15 of the cradle arm 7 as shown by the two-dot chain line, fixing the cradle arm 7. do.

Next, the package cage side yarn end suction arm 53
rotates clockwise, and the cam 55 of the same arm contacts the cam follower 28 of the cam plate 26, and the cam plate 26
returns from the position of the two-dot chain line to the position of the solid line, and the notch 3
0 and the protrusion 29 is also released, the support plate 2
0 is pulled by the spring 22, and the package pressing plate 18 is also at the solid line position. During this time, the package drive roller 56 comes into contact with the package 6 at the position indicated by the dashed line 6a, reverses the package 6, causes the suction arm 53 to suck the yarn end, and introduces the yarn end into the knotter 59. Package operation lever 51
, rotate the cradle arm 7 clockwise while keeping it in contact with the shoe 15, and move the package 6 to 6b.
position. At this time, the package drive roller 5
6 has returned to its original solid line position.

On the other hand, at this time, the spinning side yarn end suction arm 5
2 rotates as shown by the two-dot chain line, inserts its tip into the casing of the spinning device 1, and sucks the yarn being spun.
The suctioned thread passes through the thread guiding groove 54 and is connected to the knotter 59.
will be introduced in Then, the knotter 59 is activated to perform yarn splicing.

While the knotter 59 is in operation, the spun yarn is sucked into the yarn storage device 11 and accumulated as shown in 11c, but immediately after the knotter is operated, the package operation lever 5 is
1 to the upper right in FIG. 1, the package 6 is brought into contact with the friction roller 14 and winding is resumed. Package 6 is friction roller 14
After contacting, the package operating lever 51 returns to its original position.

When the knotter 59 finishes the yarn tying operation, the yarn splicing cart starts moving even if the yarn is being sucked into the yarn storage device 11.

As mentioned above, in the device of the present invention, the yarn storage device that sucks the spun yarn end until the yarn tying operation is completed during yarn cutting is provided on the spinning/winding unit side, without providing it on the yarn splicing cart. After tying the yarn with the knotter, the yarn splicing cart can resume running without waiting for the rotation of the package cage to start and the subsequent work such as pulling out the yarn from the yarn accumulating device is completed, reducing the time the yarn splicing cart stops. This can improve efficiency.
