Abstract

In the process of changing bobbins in turns and winding yarns continuously by rotating a freely rotatable turret which several bobbin holders are attached to, yarns are wound on bobbins by rotating the turret in the opposite direction of bobbins and transfering yarns automatically to the yarn accepting groove which is placed at the end of the extra bobbins.

The present invention relates to a method for switching winding of thread yarns, and to a method suitable for a continuous thread-winding machine winding apparatus of a revolving type.

In the conventional method of winding winding of thread thread, a threading bracket is installed at the end of the bobbin holder to catch the thread of thread changing or the threading bracket is integrally attached to the bobbin to catch the thread of thread switching. Doing.

)의 처리, 실걸이용 금구의 착탈등이 번잡하며, 자동화로 할 때에 많은 곤란이 있으며 또한 가령 자동화하여도 설비비가 고가이므로 경제적으로 채산성이 없는 등의 문제가 있다.Such a conventional method is a single yarn after the doping of the ten thousand bobbin.

), The mounting and detachment of the hanging bracket, etc. are complicated, and there is a lot of difficulties in the automation, and there is a problem such as economical profitability because the equipment cost is high even when automated.

The present invention has been made to solve such a problem, so that it is replaced with a conventional hanging bracket for catching thread thread, and a thread for thread thread catching is formed at the end of the bobbin to rotate the crate in the opposite direction to the bobbin rotation direction, and at the same time, To move the movements to keep.

It will be described in detail with reference to the accompanying drawings.

1 is a perspective view of an apparatus for implementing the present invention.

In the figure, thread 1 is traversed to the yard guide 3 of the traversing device 2 and wound around the bobbin 7 or 8 which is pressed by the sliding roller 4 via the sliding roller 4 and rotated at a constant speed to form a package.

Traverses device 2 and sliding roller 4 are protruded from the up and down slide rod (not shown), and above the traverse device, the thread release guide 12 is free to slide on the shafts 11 and 11 'installed in brackets 10 and 10'. On the guide rods 13 and 13 ', which are supported and mounted on the surface of the guide 12, the yarn guide 14 is attached freely for sliding.

The guide rod 13 also serves as the swing shaft of the thread release guide 12, and a sliding cylinder 16 is attached to the front end thereof with a lever 15 placed thereon. In addition, the yarn guide 17 is attached to the yarn guide 14.

9 is a litt, hereinafter referred to as litt arm or arm. The arm is free to rotate around the support point 9 'by an actuator (not shown), and the bobbin holders 5 and 6 protrude freely from the arm 9 and the bobbins 7, 8 are inserted into the holders 5 and 6. The pivot arm 9 rotates in a clockwise direction and is in a reverse direction with respect to the rotation directions (counterclockwise) of the bobbin holders 5 and 6.

7a and 8a are thread | pipe catching groove | channels, and it is provided in the circumferential direction at the edge part of bobbin 7,8.

19 and 20 are punch guides, respectively. The guide 19 or 20 on the traversing device side is a thread guide groove of bobbins 7, 8 from the position of the litter arm 9 at the time of switching by cylinders 21 or 22 installed on the litt arm 9. It protrudes to the vicinity of 7a and 8a.

Next, a description will be given of the winding-up winding method of yarn according to the present invention.

As shown in Fig. 1, when the thread is pulled out and the empty bobbin 7 is inserted into the bobbin, the bobbin thread is wound on the bobbin 7th and as shown in Figs. A preliminary run of bobbin 8 is initiated and then the actuator arm (not shown) is rotated clockwise and the wound arm P on the bobbin 7 rotates in contact with the surface of the sliding roller 4 by an actuator (not shown). When the circumferential package P is separated from the sliding roller 4 by 4, and the bobbin 8 comes into contact with the sliding roller 4 (FIG. 4), the thread release guide 12 swings in the direction A and the thread 1 is released from the eye guide 3 .

Thread 1 moves in tension to the center of traversus device 2 which is below the traversus support point.

The yarn guide 14 is moved in the B direction, and at the same time the punch guide 19 is moved in the C direction.

When thread 1 is moved to the position of thread catching groove 8a of bobbin 8 by thread guide 14, the thread 1 is prevented from being detached from over the whole package P as shown in Figs. Lose. The thread guide 14 moves the thread 1 to the thread catching groove 8a of the bobbin 8, and the thread catching groove 8a of the bobbin 8 is brought into contact with the thread 1 crossing the sliding roller 4 from the sliding roller 4.

The rotation direction of Gongbobin 8 and the direction of movement of yarn 1 are reversed.In addition, by the arm arm 9, the ball of bobbin 8 is inserted into yarn 1 and rotated arbitrarily, so that yarn 1 is captured by the thread of the gunbobin 8 of the gunbobin 8 A large tension is generated in thread 1 between the package P and the bobbin 8, and thread 1, which crosses over, is cut and winding of the thread to the 8th position of the bobbin is started. When thread 1 begins to be wound around gongbin 8, the thread guide 14 is returned to its original position. Then, when thread release guide 12 is returned to its original position, the transfer tail is placed on the 8th position of the bobbin by thread guide 9 and thread release guide 8. transfertail) is formed so that yarn 1 is captured by the eye guide 3 of traverse device 2 and enters the normal winding.

As described below, the winding winding of the thread 1 is successively alternately performed.

In the above embodiment, the punch guides 19 and 20 were attached to the litt arm, but the punch guides may be installed on the lower side of the traversing device 2 and the guides may be extruded between the bobbins 7 and 8, in particular, It is preferable to the so-called tantem method in which two bobbins are attached to a bobbin holder. In addition, in the embodiment has been described with respect to the friction drive winder, the present invention is also applied to a spindle drive winder.

Instead of lifting up and down the sliding roller and traverse device, it is also applied to the structure that moves the bobbin holder in the horizontal direction with the sliding roller and traverse device positioned.

The bobbin bobbin and the bobbin bobbin may be brought into contact with the friction roller at the same time during switching.

According to the method of the present invention as described above, it is possible to ensure the winding take-up of the thread, the single yarn processing of the helped package is also simple and automation is easy because no threading bracket is used.

Claims (1)

Rotate the bobbin holder freely on the free rotation of the bobbin and turn the bobbin to rotate the bobbin inserted into the holder alternately to take up the winding. A method for switching winding of a thread, characterized in that the thread is held by moving the thread to a groove for catching thread threaded at the end of a gongbin bin.
