Abstract

There is provided a hoop winding device, comprising: a winding table configured to have an insertion hole formed to place a mandrel at a center thereof; a drive unit configured to rotate and drive the winding table; a plurality of supports on which bobbins with wound fibers are mounted, the plurality of supports being arranged along circumference of the winding table; a first guide section configured to bundle fibers drawn from a plurality of bobbins which constitute a first bobbin group out of the bobbins respectively mounted on the plurality of supports and feed the bundled fibers to the mandrel; and a second guide section configured to bundle fibers drawn from a plurality of bobbins which are not included in the first bobbin group but constitute a second bobbin group and feed the bundled fibers to the mandrel.

First claim

The invention claimed is:

1. A hoop winding device, comprising:
one or a plurality of winding tables, each being configured to have an insertion hole formed to place a mandrel at a center thereof;
a drive unit configured to rotate and drive the one or plurality of winding tables;
a plurality of supports on which bobbins with wound fibers are mounted, the plurality of supports being arranged along circumference of the one or plurality of winding tables;
a first guide section configured to bundle fibers drawn from a plurality of bobbins which constitute a first bobbin group out of the bobbins respectively mounted on the plurality of supports, and feed the bundled fibers to the mandrel such that they are wound around the mandrel as a bundle;
a second guide section configured to bundle fibers drawn from a plurality of bobbins which are not included in the first bobbin group but constitute a second bobbin group out of the bobbins respectively mounted on the plurality of supports, and feed the bundled fibers to the mandrel such that they are wound around the mandrel as a second bundle; and
a frame configured to support the one or plurality of winding tables, the first guide section and the second guide section.

2. The hoop winding device according to claim 1 ,
wherein the first guide section and the second guide section have different lengths in an axial direction of the mandrel.

3. The hoop winding device according to claim 1 ,
wherein at least one of the first guide section and the second guide section has an adjuster to change a length in an axial direction of the mandrel.

4. The hoop winding device according to claim 1 ,
wherein the supports on which the bobbins included in the first bobbin group are mounted and the supports on which the bobbins included in the second bobbin group are mounted are placed on the same winding table.

5. The hoop winding device according to claim 4 ,
wherein the first guide section and the supports on which the bobbins included in the first bobbin group are mounted are placed on one surface of the winding table, and
the second guide section and the supports on which the bobbins included in the second bobbin group are mounted are placed on the other surface of the winding table.

6. The hoop winding device according to claim 1 ,
wherein the one or plurality of winding tables include:
a first winding table; and
a second winding table arranged concentrically with the first winding table, and the drive unit includes:
a first drive unit configured to rotate and drive the first winding table; and
a second drive unit configured to rotate and drive the second winding table, wherein the supports on which the bobbins included in the first bobbin group are mounted are placed on the first winding table and the supports on which the bobbins included in the second bobbin group are mounted are placed on the second winding table.

7. The hoop winding device according to claim 1 ,
wherein number of the bobbins included in the first bobbin group and number of the bobbins included in the second bobbin group are respectively equal to or smaller than five.

8. A filament winding apparatus, comprising:
the hoop winding device according to claim 1 .
