2. Description of the Related Art As a yarn traversing device as described above,
Conventionally, the one disclosed in JP-A-59-194977 is known.

FIG. 8 is a plan view of a yarn traversing device constructed based on the above conventional example, and FIG. 9 is a schematic side view thereof. In these figures, 01 ... The traverse mechanism provided so as to correspond to the upstream side in the yarn winding direction of each of the plurality of bobbins 02 is shown.

Each of the traverse mechanisms 01 ... Rotates around the first rotary shaft core P1 to guide and move the yarn Y toward one side in the rotary shaft core direction of the bobbin 02. 03, and rotates in the opposite direction to the first traverse blade 03 around the second rotation axis P2 which is deviated from the first rotation axis P1 in a direction parallel to the rotation axis of the bobbin 02. Three second traverse blades 04 for guiding and moving the yarn Y to the other side in the direction of the rotation axis of the bobbin 02.
It consists of and.

First and second traverse blades 03
Each of the ..., 04 ... is provided with a phase difference of 120.degree.
In the case of the first traverse blades 03, 03, the first traverse blades 03, 03 are the same as each other in the first and second traverse blades 03, 03.
So that they rotate in opposite directions in the plane of
The traverse blades 04, 04 are configured to rotate in opposite directions in the same second plane, which is offset from the first plane described above in the direction of the axis of rotation.

Further, the first traverse blade 03,0

[0007]

However, in the configuration of the above-mentioned conventional example, in the adjacent traverse mechanisms 01, 01, the first and second traverse blades 03, 04 are provided.
Both of them rotate in the opposite directions and rotate in the same plane. Therefore, when attempting to attach / detach the traverse mechanism 01 at the intermediate position as a unit in the direction orthogonal to the axis of the rotation axis for repair and inspection, etc. , For example, the first
When the traverse blades 03, 03 of No. 1 are rotated so as not to interfere with each other, conversely, the second traverse blade 0
4,04 will rotate in the direction of mutual interference,
It is difficult to prevent the first and second traverse blades 03, ..., 04 from interfering with each other, and it takes a lot of time to attach and detach the traverse mechanism 01, resulting in a troublesome repair inspection.

Further, in the adjacent traverse mechanisms 01, 01, since the first traverse blades 03 ... And the second traverse blades 04 ... Are both rotated in the same plane, the adjacent traverse blades are There is a drawback in that the traverse device is expensive in terms of manufacturing because it interferes with each other and precision is required for assembling them.

In the adjacent traverse mechanisms 01, 01, the first and second traverse blades 03, 0
Since the rotation direction is opposite to any of the four, the same shape cannot be used, and two kinds of each of the first and second traverse blades 03 and 04 must be prepared,
There is a drawback that the device cost becomes high.

The reason why the same shape cannot be used as described above is that the yarn Y is smoothly released when the yarn Y is transferred between the first traverse blade 03 and the second traverse blade 04. This is because the tip end portion is formed with a taper surface F that is inclined with respect to the yarn winding direction and the radial directions of the rotation trajectories C1 and C2, and the shape of the taper surface F is different as the rotation direction is different.

Further, since there are two types of the first and second traverse blades 03, 04 respectively as described above, it is necessary to take care not to assemble the same type to the adjacent ones at the time of assembling. However, there is a drawback in that it requires skill and labor for assembling, and is expensive in this respect as well.

The present invention has been made in view of the above circumstances, and the yarn traversing device according to the first aspect of the present invention enables each traverse mechanism to be provided only by making a simple improvement in the arrangement. The yarn traversing device of the invention according to claim 2 can be easily attached and detached and can be manufactured at low cost, and the same kind of traverse mechanism can be used as the traverse mechanism. The purpose is to be able to make it inexpensive in any of the aspects.
