Description

Yarn winder for preventing yarn from outmost inner and outer bunch concentration and yarn transferring method using the same}

The present invention relates to a yarn winding device capable of preventing the formation of the innermost and outer layer bunches and a yarn transfer method using the same.

Referring to FIG. 1A, a yarn winding apparatus according to the related art, a yarn transfer method, and a yarn cutting method therethrough are illustrated. Referring to FIG. 1B, a cake in which innermost and outer layer bunch concentration is generated is illustrated.

As shown in FIG. 1A, the conventional four winding device 100 ′ is a rotatable rotary drum 110 ′ and a bobbin holder 111 ′ rotatably coupled to the upper and lower portions of the rotary drum 110 ′, respectively. 112 'and a traverse roller portion 120' positioned at an upper portion of the rotary drum 110 'to allow the yarn to be wound around the bobbin holders 111' and 112 'with a predetermined width, and the bobbin. It consists of a friction roller 130 'in contact with the yarn to provide a predetermined pressure. Here, the bobbin may be called a branch pipe, and the state in which the bobbin is wound around the bobbin may be called a cake.

In the four winding device 100 ', for example, when the upper bobbin becomes the man bobbin 113', the rotary drum 110 'is rotated by a predetermined angle so that the manbobin 113' and the ball bobbin 114 'are rotated. The positions of are interchanged. That is, as shown in Figure 1a, the rotary drum 110 'is rotated so that the bobbin 114' is located at the top, the manbobin 113 'is located at the bottom.

In this state, the yarn Y is transferred to the upper bobbin 114 'and simultaneously cut. To this end, the traverse roller portion 120 'and the friction roller portion 130' rise upwardly from the rotary drum 110 'by a predetermined height, and then the lower manbobin 113' stops rotating. Then, since the upper bobbin 114 'continues to rotate, the yarn Y is transferred to the upper bobbin 114', and the saga between the mann bobbin 113 'and the bobbin 114' is moved. Forcibly cut.

However, the conventional yarn winding device and the yarn transfer and cutting method according to the related art have a problem that the bunches are concentrated on the outermost side of the man bobbin during transfer and cutting of the yarn. That is, as shown in FIG. 1B, the outermost layer side bunch SB in which yarns are wound around the outermost side of the cake C formed on the manbobin is generated.

This problem is not only that the yarn between the manbobin 113 'and the gongbobin 114' is directly transferred and cut at the time of yarn transfer and cutting, but also after the yarn is transferred to the transfer and cutting position, the manbobin 113 'and the gazette. It is believed that after the bin 114 'is rotated many more times, the transfer and cutting of the yarn is made. In particular, the side bunch (SB) formed on the outermost layer of the cake (C) formed on the manbobin must be manually removed by a person before shipping the product, thereby reducing the productivity of four winding.

In addition, in the conventional yarn winding apparatus and thus the yarn transfer and cutting method, the traverse roller portion 120 'and the friction roller portion 130' are raised by a predetermined height from the rotating drum 110 'during transfer and cutting of the yarn. In addition, there is a problem in that the bunching is formed on the innermost layer of the Gongbobin, which is newly wound up. That is, as shown in FIG. 1B, the innermost middle bunch bunch MB in which yarns are wound intensively in the center of the cake C formed by the bobbin is generated.

Such a problem is known to occur because the traverse roller portion 120 'and the friction roller portion 130' ascend from the rotating drum 110 'by a predetermined height during yarn transfer and cutting. That is, since the distance from the bobbin 114 'to the traverse roller part 120' is relatively far, the yarn is wound up centrally in the bobbin center part at the beginning of winding. In this way, if the middle bunch occurs on the bobbin, there may be a problem in the post-processing process such as dyeing due to the difference in the tension of the yarn at the time of disintegration for manufacturing various fabrics, and in severe cases, the thread may be broken. Can be.
