Description

[Detailed description of the invention] The present invention has a cylindrical shape that is rotatable around a horizontal axis, and a fiber roll located on the horizontal axis, and the fibers on this fiber roll are moved inside the cylindrical shape. This relates to a centrifugal molding device that rolls up onto a peripheral surface.

In such a centrifugal forming apparatus, the conventional fiber roll is a cylindrical body, and the proximal ends of the fibers wound around the fiber roll are held by a number of needles erected from the fiber roll. According to this conventional holding method, it was not easy to lock the proximal end to the needle group during winding, and it was also difficult to separate the proximal end from the needle group at the same time and easily at the end of winding. .

The present invention aims to solve the above problems.

That is, the present invention has a cylindrical shape rotatable around a horizontal axis and a fiber roll located on the horizontal axis, and the fibers on this fiber roll are wound onto the inner peripheral surface of the cylindrical shape. In the centrifugal forming apparatus, the fiber roll is composed of spiral-shaped elastic plates whose overlapping parts are urged to be separated from each other, and a rod is inserted into the fiber roll, and the rod and the inner circumferential surface of the fiber roll are inserted. A plurality of points are connected by links, and the overlapping portions are configured to approach each other by pushing the rod, and a spring is provided to press and bias the rod, and the proximal end of the fiber is held by the overlapping portion. This paper proposes a fiber roll in a centrifugal forming apparatus configured as follows. According to this configuration, by pushing the rod using the spring force and bringing the overlapping parts closer to each other, the proximal end of the fiber can be easily and reliably held by the overlapping part, and the rod can be pulled against the spring force. In this way, the overlapping parts can be moved apart from each other, and the proximal end can be easily separated over the entire length at the same time when the winding is completed.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIG. 1, numeral 1 has a cylindrical shape with end jigs 2 at both ends, and is supported by a plurality of wheels 3 so as to be rotatable around a horizontal axis 4. As shown in FIG. Reference numeral 5 denotes a trolley that can run while being guided by rails 6. A fiber roll 7 movable on the horizontal axis 4 is provided from the front of the trolley, and this fiber roll 7 has a fiber (cloth-like reinforcing fiber) 8 wound thereon. I am wearing it.
As shown in FIGS. 2 to 4, the fiber roll 7 is made of a spirally wound elastic plate, and the overlapping portion formed by both ends 7a and 7b is urged to be separated from each other. A rod 9 is disposed extending from inside the fiber roll 7 to inside the trolley 5,
The rod 9 is connected to the inner peripheral surface of the fiber roll 7 by links 10 at a plurality of locations in the circumferential direction. and rod 9
By pushing the fibers from the cart 5 side to the fiber roll 7 side, the overlapping parts are moved closer to each other against the elasticity of the fiber rolls 7. A cylinder 11 into which the rod 9 is inserted is provided in the truck 5, and a cylinder 11 is provided between the cylinder 11 and a receiving plate 12 attached to the rod 9 to push the rod 9 toward the fiber roll 7. A biasing spring 13 is provided.

The action will be explained below. The fiber roll 7 is pulled out from the cylindrical mold 1.
The fiber 8 is wound around the fiber 8. That is, the rod 9 is pulled against the spring 13, and both ends 7a, 7b of the fiber roll 7 are separated from each other by utilizing the elastic force of the fiber roll 7. Then, the fiber end 8a is inserted between the separated ends 7a and 7b. Then, the pulling force of the rod 9 is released and the rod 9 is pushed in by the elastic force of the spring 13. As a result, both ends 7a and 7b of the fiber roll 7 move toward each other against its own elasticity, and the fiber base end 8a is held (pinched) by the ends 7a and 7b. and proximal end 8
The fiber 8 holding a is wound around the fiber roll 7. Next, as shown in FIGS. 1 and 3, the fiber roll 7 is inserted into the cylindrical mold 1, and the fiber 8 is opposed to the inner peripheral surface of the cylindrical mold. Then, the cylindrical mold 1 and the fiber roll 7 are rotated relative to each other, and the fibers 8 on the fiber roll 7 are rolled onto the inner peripheral surface of the cylindrical mold. Almost completely rolled,
The rod 9 is pulled to separate the ends 7a and 7b, and the holding of the fiber proximal end 8a by the ends 7a and 7b is released as shown in FIG. As a result, the fiber base end 8a is completely removed from the fiber roll 7 side and transferred to the cylindrical mold 1 side.

According to the fiber roll in the centrifugal forming apparatus of the present invention described above, by pushing the rods with spring force and bringing the overlapping parts closer to each other, the proximal ends of the fibers can be easily and reliably held by the overlapping parts. Moreover, by pulling the rod against the spring force, the overlapping parts can be moved apart from each other, so that the proximal end can be easily removed over the entire length at the same time when the winding is completed.
