DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn winding device.

[0002]

2. Description of the Related Art A hollow fiber type processing apparatus using a hollow fiber module comprising a large number of hollow fibers has been widely used for blood treatment, reverse osmosis, heat exchange, and the like. By the way, in order to obtain the hollow fiber module as described above, first, the hollow fiber is wound by a winding device, and the wound material is cut into a predetermined length to form a hollow fiber bundle. A method of obtaining a hollow fiber module from the method is employed.

The applicant of the present application has already proposed such a hollow fiber winding device in Japanese Patent Application No. 1-344836. In this case, as shown in FIG. 9 and FIG.
Bobbin 5 wound with a twine yarn 52 composed of two hollow fibers 51
3 is driven to rotate, the yarn 52 is sent out from the bobbin 53, and the winding body 54 is driven to rotate, so that the sent yarn 52 is wound around the winding body 54. Have been. By the way, at the time of the above-mentioned winding, in order to wind the yarn 52 around the winding body 54 without loosening, the yarn 52
Need to be tensioned. Further, when the yarn 52 is sent out from the bobbin 53, the feeding position of the yarn 52 reciprocates in the axial direction of the bobbin 53 as it is sent out and moves inward in the radial direction of the bobbin 53. In response to this movement, the yarn 52 is wound into the winding body 5.
It is also necessary to guide well to 4. Therefore, as shown in FIGS. 11 to 13, between the bobbin 53 and the winding body 54, there is provided a tension pulley 55 for applying tension to the yarn 52, and the tension pulley 55
Has a V-shaped groove 56, and the V-shaped groove 56 guides the plying yarn 52.
It is possible to cope with the movement of the sending position of the yarn 52 on the bobbin 53.

[0004]

By the way, in the above conventional example, when each hollow fiber 51 of the plying yarn 52 composed of four hollow fibers 51 passes through the V-shaped groove 56 of the tension pulley 55, As shown in FIG. 13, each hollow fiber 51 may be guided at a different position on the side surface of the V-shaped groove 56 in the radial direction. In this case, tension pulley 5
In FIG. 5, the peripheral speeds of the portions of the plying yarns 52 where the hollow fibers 51 contact each other are different, and as shown in FIG.
A deviation occurs between the hollow fibers 51 constituting the plying yarn 52. In this state, when the yarn 52 is wound around the winding body 54, the yarn 52 is not wound orderly on the winding body 54, and the hollow fiber 51 is wound in a floating state. Therefore, when the plying yarn 52 is further wound thereon, the hollow fiber 51 is broken or bent. If the hollow fiber 51 is bent or bent as described above, it is necessary to carry out a reworking operation in a later step, and there is a problem in that the efficiency is low and a defect occurs in a final product stage. In order to solve this problem, it is conceivable to reduce the sending speed of the yarn 52 from the bobbin 53 or the winding speed of the yarn 52 of the winding body 54. However, in this case, the production efficiency is reduced. A new problem of lowering occurs. An object of the present invention is to provide a yarn winding device that can solve all of the above problems.

[0005]

Means for Solving the Problems In order to achieve the above object, a feature of the present invention is that a bobbin wound with a ply yarn consisting of a plurality of single yarns is driven to rotate, and In the yarn winding device in which the yarn is sent out and the winding body is driven to rotate and the sent yarn is wound on the winding body, the yarn winding yarn is wound between the bobbin and the winding body. And a tension pulley for applying tension to the plying yarn are arranged in the feeding direction of the plying yarn in the above order, and the guide pulley device has an axis parallel to the axis of the bobbin. And a pair of first guide pulleys arranged in close proximity to each other to guide the yarn yarn between the two, and a pair of first guide pulleys near the first guide pulleys and being orthogonal to the first guide pulley and mutually It is arranged in close proximity and guides the yarn between them. A pair of second guide pulley to the first and second guide pulley and a tension pulley is in the point that is a flat pulley. Incidentally, the single yarn may be a hollow fiber.

[0006]

When winding the yarn, the bobbin is driven to rotate and the winding body is driven to rotate. As a result, the yarn is fed from the bobbin, and the sent yarn is guided in the radial direction of the bobbin by the pair of first guide pulleys of the guide pulley device, and the pair of first yarns of the guide pulley device are also guided. The bobbin is guided in the axial direction by two guide pulleys. Then, the yarns guided by the first and second guide pulleys are given a desired tension by the tension pulleys, and are wound by the winding body without slack. In the above case, when the yarn is fed from the bobbin, the yarn feeding position reciprocates in the axial direction of the bobbin as the yarn is fed and moves radially inward of the bobbin. At this time, a pair of first axes having an axis parallel to the axis of the bobbin is provided.
A guide pulley guides the plying yarn between the two, and guides the plying yarn in response to the delivery position of the plying yarn moving inward in the radial direction of the bobbin. A pair of second guide pulleys having a pair of guides guide the plying yarn between the two and guide the plying yarn in response to the reciprocating movement of the plying yarn in the axial direction of the bobbin. Even if the sending-out position moves in the axial direction and the radial direction of the bobbin, the twine yarn is favorably guided to the winding body. Further, since the first and second guide pulleys and the tension pulley are flat pulleys, the single yarns of the ply yarn composed of a plurality of single yarns are the same in the radial direction of the first and second guide pulleys and the tension pulley. Guided by position. Therefore, in the first and second guide pulleys and the tension pulley, the peripheral speeds of the portions where the single yarns of the plying yarns abut are not different, and therefore, between the single yarns forming the plying yarns. There is no deviation, and the plying yarn is wound in a regular state on the winding body, and the single yarn on the winding body does not break or bend.
