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 constituted by a pair of half-pipe bodies that can be opened and closed via a hinge, and a spring is provided to bias these half-pipe bodies to open and close, and the fiber rolls are provided with a spring that biases the half-pipe bodies to open and close. A closing movement imparting tool for closing the half pipe body is provided, and the end face of the opening of both half pipe bodies is configured to clamp the base end of the fiber, and the clamping end face is formed into a rough surface. This paper proposes a fiber roll for use in a centrifugal forming apparatus, which is provided with a regulating device on the inside to regulate the amount of protrusion of the proximal end of the fiber. According to this configuration, by closing both half-pipe bodies against the spring by the closing movement imparting tool, the proximal end of the fiber can be easily and reliably closed by the roughened both end surfaces of the opening. By releasing the closing movement imparting device, both half-pipe bodies can be opened using spring force. This can be done simultaneously and easily.

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 5, the fiber roll 7 is composed of a pair of half pipe bodies 7A and 7B that can be opened and closed via a hinge 9. Inside the fiber roll 7 are both half pipe bodies 7A and 7B.
A spring 10 is provided to bias the opening. In the embodiment, a C-shaped leaf spring is shown as the spring 10, but this may also be a tension spring. Reference numeral 11 denotes both half pipe bodies 7A and 7B against the spring 10.
A closing movement imparting device that moves the fiber roll 7 to close.
A rod 12 disposed from the inside to the inside of the trolley 5,
Links 13A and 13B connecting this rod 12 and the inner surfaces of both half-pipe bodies 7A and 7B, a cylinder 14 through which the rod 12 is inserted inside the truck 5, a receiving plate 15 attached to the rod 12, and the cylinder 14. a compression spring 16 disposed between the rod 12 and urging the rod 12 to protrude;
It consists of a removable pin 17 for positioning the rod 12 when it is retracted against the force of the rod.A tension spring can be used in place of the links 13A and 13B, and a wire can be used in place of the rod 12. Opening end surface 7 of both half pipe bodies 7A, 7B
The opening end faces 7a and 7b are formed to have rough surfaces, and the base end 8a of the fiber is held between the opening end faces 7a and 7b. A restrictor 18 is provided inside the opening to restrict the amount of protrusion of the fiber proximal end 8a, and the restrictor 18 mainly consists of a rubber body in the shape of a half-split pipe.

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 pin 17 is removed and the rod 12 is moved in a protruding manner by the elastic force of the compression spring 16, thereby causing the link 1 to move.
3A, 13B and the elastic force of the spring 10, the two half pipe bodies 7 are attached around the hinge 9.
A and 7B are opened to separate both opening end faces 7a and 7b. The fiber proximal end 8a is then inserted between the opening end surfaces 7a and 7b, and the amount of insertion is regulated by coming into contact with the regulating tool 18. In addition, the restrictor 18 has a fiber base end 8a.
This prevents the rods from becoming entangled with the rod 12 and links 13A and 13B. Next, both springs 10,1
6, pull the rod 12, and separate the two half-pipe bodies 7.
A, 7B are moved to close, and the fiber base end 8a is held (pinched) by both opening end surfaces 7a, 7b. This clamping position is maintained by inserting the pin 17. And the fiber 8 whose proximal end is held
is wound around the fiber roll 7. Then the first
A fiber roll 7 is inserted into the cylindrical mold 1 as shown in FIGS. 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 peripheral surface of the cylindrical mold. When the fiber is almost completely wound, the pin 17 is pulled out and the two half pipe bodies 7A, 7B are opened to release the fiber proximal end 8a from being held by the opening end surfaces 7a, 7b. 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 as described above, by closing the two half pipe bodies against the spring by the opening motion imparting tool, the fiber roll is formed by the opening end face formed in a rough surface. The base end of the pipe can be easily and reliably held, and by releasing the closing motion imparting tool, the two half-pipe bodies can be opened using the spring force. Proximal detachment can be performed simultaneously and easily over the entire length. In addition, the regulating device can regulate the protrusion amount of the proximal end of the fiber to a length that is easy to remove, and can prevent the proximal end of the fiber from becoming entangled with other objects.
