DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braid winding device for winding a braid formed by a braider onto a bobbin.

[0002]

2. Description of the Related Art Conventionally, a braid formed by a braider is pinched and pulled out by a nip roller and wound on a bobbin, or a braid formed by a braider is directly used without using a nip roller. There is known a braid take-up device adapted to take up a bobbin.

Are not limited to those described above, and various known traverse mechanisms can be adopted.

The braid b formed around the mandrel 4 and pulled out from the mandrel 4 in a substantially horizontal direction is guided by the guide roller 11 and is positively driven for rotation disposed below the guide roller 11. The direction is changed to the pair of feed rollers 13 and 14. Next, as shown in FIG. 2, the feed rollers 13 and 14 are wound in a figure-eight shape, and then, through the feed rollers 13 located above, by the traverse guide 24 c of the traverse mechanism 24. While being reciprocated along the axis of the winding bobbin 19, it is wound on the winding bobbin 19.

As described above, the braid b pulled out from the mandrel 4 in the substantially horizontal direction is wound around the feed rollers 13 and 14 which are positively driven to rotate in the shape of a figure 8, so that they do not slip. , Surely, and
At a constant speed, it is pulled out of the mandrel 4 by the feed rollers 13 and 14.

Is mounted on a machine of the next process such as a resin impregnating device. Accordingly, the composition speed of the blader B and the winding speed of the winding bobbin 19 can be freely set without considering the processing capability of the next step such as a resin impregnating device, so that the productivity of the blader B is reduced. Will be improved.

Further, according to the composition speed of the braid b of the braider B, the rotation speed of the motor 16 is appropriately controlled,
Alternatively, by replacing the pulleys described above, the winding speed of the braid b on the winding bobbin 19 can be freely set independently of the composition speed of the braid b of the braider B. Therefore, the braid of the braid b is made coarser or denser, or the winding speed of the braid b is increased to make the braid b thinner, or the winding speed of the braid b is made slower to make the braid b thicker. The composition operation can be performed under various conditions.

In addition, by disposing a hollow guide member 28 as shown in FIG. 3 in front of the bobbin 5 for the center thread, a braid b without a twisted portion is incorporated.
Can be composed. Of course, when the flat yarn y and the flat center yarn y 'are not used, it is not necessary to use the bobbin carrier C and the hollow guide member 28 as described above.

[0031]

Since the present invention is configured as described above, the following effects can be obtained.

The braid is wound around the feed roller in the shape of a figure 8 and actively pulled out, so that the braid can be wound on the winding bobbin reliably and at a constant speed without slipping. Comes out. Therefore, a braid having a constant mesh can always be formed. Further, since the braid is configured to be pulled out by the positively rotating feed roller, it is possible to prevent the braid from being damaged when the braid is pulled out while being pinched by a nip roller or the like.

Since the braid formed around the mandrel is pulled out by a pair of feed rollers,
Variations in the speed at which the braid is extracted from the mandrel can be prevented, and thus a braid having improved quality can be formed.

Since the composition speed of the braid of the braider and the speed of winding the braid onto the winding bobbin can be set independently and separately, the composition of the braid can be performed under various conditions.
