Abstract

A filament winding apparatus includes a working area in which an operator performs an operation to at least one bobbin and/or liner on a conveyance path, an operation area in which a winder is driven, a buffer area between the working area and the operation area in a conveyance direction on the conveyance path, and an outside area that is neither the working area, the operation area, nor the buffer area being provided; and first fixed fences provided at borders between (i) the operation area and the buffer area and (ii) the working area and at the borders between (I) the operation area and the buffer area and (II) the outside area; and a first door provided at a border between the working area and the buffer area, and wherein the buffer area includes an accumulator portion capable of accumulating the at least one bobbin and the liner.

First claim

The invention claimed is:

1. A filament winding apparatus comprising:
a winder that detachably supports at least one bobbin on each of which a fiber bundle is wound and configured to wind the fiber bundle taken out from the bobbin onto a liner; and
a conveyance device including a conveyance path through which the at least one bobbin and the liner are carried in and out from the winder,
in the filament winding apparatus, a working area in which an operator performs an operation to the at least one bobbin and/or the liner on the conveyance path,
an operation area in which the winder is driven,
a buffer area between the working area and the operation area in a conveyance direction on the conveyance path, and
an outside area that is neither the working area, the operation area, nor the buffer area being provided,
the filament winding apparatus further comprising:
first fixed fences provided at borders between (i) the operation area and the buffer area and (ii) the working area and at the borders between (I) the operation area and the buffer area and (II) the outside area; and
a first door provided at a border between the working area and the buffer area, and wherein
the buffer area includes an accumulator portion capable of accumulating the at least one bobbin and the liner.

2. The filament winding apparatus according to claim 1 , wherein a second fixed fence and a second door are provided at a border between the working area and the outside area.

3. The filament winding apparatus according to claim 2 , further comprising:
an unlocking operation unit operated by the operator to unlock the second door; and
a control unit configured to control the first door and the second door, wherein,
when the unlocking operation unit is operated, the control unit unlocks the second door and locks the first door.

4. The filament winding apparatus according to claim 3 , further comprising a locking operation unit operated by the operator from the outside area to lock the second door, wherein
the control unit maintains the first door in a locked state during a period after operation of the unlocking operation unit and before operation of the locking operation unit.

5. The filament winding apparatus according to claim 1 , further comprising a human detection unit capable of detecting the operator in the working area.

6. The filament winding apparatus according to claim 5 , further comprising a control unit configured to control the first door, wherein,
when the human detection unit detects that the operator is in the working area, the control unit locks the first door.

7. The filament winding apparatus according to claim 1 , wherein
the winder detachably supports a cartridge to which a plurality of the at least one bobbin are attached, and
the conveyance device carries the cartridge in and out from the winder.

8. The filament winding apparatus according to claim 7 , wherein the first door in an open state is sized to allow at least one of the cartridge or the liner to pass through the first door.

9. The filament winding apparatus according to claim 1 , wherein the fiber bundle is wound onto the liner that is used as a hydrogen tank mounted on a fuel cell vehicle.

10. The filament winding apparatus according to claim 2 , further comprising a human detection unit capable of detecting the operator in the working area.

11. The filament winding apparatus according to claim 3 , further comprising a human detection unit capable of detecting the operator in the working area.

12. The filament winding apparatus according to claim 4 , further comprising a human detection unit capable of detecting the operator in the working area.

13. The filament winding apparatus according to claim 2 , wherein
the winder detachably supports a cartridge to which a plurality of the at least one bobbin are attached, and
the conveyance device carries the cartridge in and out from the winder.

14. The filament winding apparatus according to claim 3 , wherein
the winder detachably supports a cartridge to which a plurality of the at least one bobbin are attached, and
the conveyance device carries the cartridge in and out from the winder.

15. The filament winding apparatus according to claim 4 , wherein
the winder detachably supports a cartridge to which a plurality of the at least one bobbin are attached, and
the conveyance device carries the cartridge in and out from the winder.

16. The filament winding apparatus according to claim 5 , wherein
the winder detachably supports a cartridge to which a plurality of the at least one bobbin are attached, and
the conveyance device carries the cartridge in and out from the winder.

17. The filament winding apparatus according to claim 6 , wherein
the winder detachably supports a cartridge to which a plurality of the at least one bobbin are attached, and
the conveyance device carries the cartridge in and out from the winder.

18. The filament winding apparatus according to claim 2 , wherein the fiber bundle is wound onto the liner that is used as a hydrogen tank mounted on a fuel cell vehicle.

19. The filament winding apparatus according to claim 3 , wherein the fiber bundle is wound onto the liner that is used as a hydrogen tank mounted on a fuel cell vehicle.

20. The filament winding apparatus according to claim 4 , wherein the fiber bundle is wound onto the liner that is used as a hydrogen tank mounted on a fuel cell vehicle.
