Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiple yarn winding machine for traversing and winding a plurality of yarns by a plurality of traverse units. [0002] In general, when winding a yarn spun from a spinning machine, a bobbin mounting spindle rotatably mounted on the machine frame and a spindle located above the spindle, There is used a winder constituted by a traverse device which is mounted so as to be able to move up and down. The traverse device installed in the winder for winding the yarn at a high speed has a pair of rotating bodies rotatably installed on the frame body at a predetermined interval and is attached to each rotating body. And a plurality of blades and a thread guiding guide attached to the frame so as to be located within the rotation trajectory of the thread guiding edge portion of the blade form one traverse unit, and the traverse unit is mounted on the bobbin. A plurality of units are provided at a predetermined interval in the axial longitudinal direction of the spindle, and a touch roller is rotatably attached to the frame body so as to be positioned close to the downstream side of the blade of the traverse unit. A traverse device having a traverse unit as described above is disclosed, for example, in Japanese Utility Model Publication No. 60-11000 and Japanese Patent Publication No. 3-72544. In recent years, in order to improve the winding ability, the number of bobbins for inserting the spindle is increased (4 to 8).
doing. However, when the length of the spindle is increased, the bending angle of the yarn from the yarn splitting fulcrum guide provided immediately below the godet roller on the upstream side to the swing fulcrum positions of the winding portions at both ends of the spindle is increased, and the yarn in the guide portion is increased. The running resistance of the thread increases, and the thread quality decreases. It is necessary to apply a high tension for winding, and the unwinding property of the package is deteriorated. For this reason, the distance between the traverse unit and the swing fulcrum guide and the thread split fulcrum guide installed upstream of the swing fulcrum guide are limited due to the bending angle restrictions of the swing fulcrum guide section and the yarn split fulcrum guide immediately below the Gode roller. However, if the number of traverse units increases, the heights of the yarn splitting fulcrum guide upstream of the swing fulcrum guide and the gody roller become higher, which makes threading operation difficult. In addition, there is a problem that the height of the entire machine stand becomes high and can be installed only in a building with a high ceiling. [0008] The first problem is that the height of the yarn splitting fulcrum guide upstream of the swing fulcrum guide and the godie roll becomes high, which makes the threading operation difficult. . The second problem is that the height of the entire machine base becomes high and it can be installed only in a building with a high ceiling. In order to solve the first and second problems, a multi-thread winding machine according to the present invention has a traverse unit arranged at least at one end thereof. The yarn is rotated on a plane that intersects with the yarn traveling direction at the position where the yarn comes into contact with the traverse guide, and the straight line connecting both ends of the traverse area of the traverse unit and the axis of the touch roller are not arranged in parallel. It has a configuration. Further, the traverse unit is mounted on the frame body such that the pair of rotary bodies are rotatably mounted on the frame body, a plurality of blades are mounted on each of the rotary bodies, and the rotation trajectory of the blades. It is preferable that it is constituted by a guide for thread guidance.

A traverse device 3 is attached to a guide 1a formed on the machine frame 1 so as to be vertically movable. Above the traverse device, traverse fulcrum guides 30-1 to 30-4 and a yarn splitting fulcrum guide 31 are installed. The traverse device 3 is positioned above the slider 4 and the spindle 2 which is engaged with the guide 1a formed on the machine frame 1 and moves up and down in the vertical direction, and is parallel to the spindle 2.

Letting (E) be the position of the thread splitting fulcrum guide 31 provided directly above the center position of the traverse fulcrum guide 30-1 and the traverse fulcrum guide 30-4, the traverse end position (B) and the traverse fulcrum guide 30- The bending angle (θ-5) of the yarn formed by the 1 position (D) and the yarn dividing fulcrum guide 31 position (E) is
In order to prevent the yarn running resistance from increasing and the yarn tension unevenness on the upstream side to occur, it is preferable to set the angle to about 20 °. Therefore, the height position (E) of the thread dividing fulcrum guide 31 is set to the traverse end position (B) in the traverse unit 6-1, the traverse fulcrum guide 30-1 position (D),

Each support member 10 is framed so that 3 and 6-4 are rotated counterclockwise (θ-3, θ-4) degrees opposite to the traverse units 6-1 and 6-2 described above. The screw 11 is rotated along an arcuate step 5a formed on the screw 5 to adjust its position.

The yarn contact positions of the traverse end portion (A) and the traverse end portion (B) on 23 are displaced in the left-right direction. Therefore, first, the position (D ') of the traverse fulcrum 30-1 is set so that the length of the yarn path (D', A, F) is equal to the length of the yarn path (D ', B, F). ) Is determined.

When (θ-5) = (θ-9) without changing 5), the position (E2) of the above-mentioned thread splitting fulcrum guide 31 becomes (E3) and becomes the first position of the thread splitting fulcrum guide 31 (E).

The bending angle (θ-10) of the yarn at the position (E3) of the thread dividing fulcrum guide 31 is larger than the bending angle (θ-6) of the yarn at the position (E) of the thread dividing fulcrum guide 31. However, the bending angle (θ-8) of the yarn is smaller than the bending angle (θ-9) of the yarn, and the maximum bending angle is (θ-9), which is the same as when the traverse unit is not rotated. In the above-described multi-thread winding machine, the number of traverse units is 4, the traverse width is 200 mm, the distance between traverse units is 230 mm, the rotation angle (θ-1) of the traverse unit 6-1 and the traverse.

If the bending angle (θ-9) of the thread at -4 is set to 20 °,
The height from the traverse fulcrum guides 30-1 and 30-4 positions (D ') to the thread dividing fulcrum guide 31 position (E3) is 135.
The height is 3 mm, which is 502 mm lower than the height of 1855 mm when the conventional traverse unit is not rotated. At this time, the reduced length of the traverse width by rotating the traverse units 6-1 and 6-4 by 2.5 ° is (1-cos 2.5 °) × 200 = 0.2 ( mm), which is extremely small and can be ignored. Further, the number of traverse units is 8, the traverse width dimension is 123 mm, the traverse unit interval dimension is 153 mm, and the rotation angle of the traverse unit 6-1 (θ

The height dimension up to 3) is 2390 mm, and the height dimension is 2880 mm when the conventional traverse unit is not rotated.
Compared with, it can be lowered by 490 mm. If the position of the yarn splitting fulcrum guide 31 is not lowered, the bending angle of the yarn can be reduced. According to the multi-thread winding machine of the present invention, the traverse unit disposed at at least one end crosses the traveling direction of the yarn at the position where the yarn comes into contact with the traverse guide. For guiding the yarn in the traverse unit, the traverse unit is rotated so that the straight line connecting both ends of the traverse area of the traverse unit and the axis of the touch roller are not parallel to each other. The traverse center position of the guide can be moved in the direction of the traverse unit installed on the opposite side, and the yarn splitting fulcrum guide and godie roll on the upstream side of the oscillating fulcrum guide in a state where the bending angle of the yarn in the oscillating fulcrum guide does not change. The length of the machine is shorter, the threading operation is easier, and the height of the machine base is lower. Can be placed. Further, the traverse unit is attached to the frame body so as to follow a pair of rotating bodies rotatably attached to the frame body, a plurality of blades attached to each of the rotating bodies, and a rotation locus of the blades. If it is configured with the guide for thread guide,
The configuration of the entire traverse device can be simplified.
