BACKGROUND ART Conventionally, as shown in FIG. 11, a long glass fiber 2 wound around a core material 1 is unwound and guided into a resin liquid tank 4 via a plurality of guide rollers 3. A fiber-reinforced resin tube 6 is formed by winding the glass fiber 3 impregnated with a resin liquid around the outer circumferential surface of a rotary mold 5 that rotates in the direction of arrow A, and then the rotary mold 5 is removed from the drive shaft and placed in the bed as shown in FIG. Then, the claw 9 provided at the tip of the piston rod of the cylinder 8 is engaged with the end of the fiber-reinforced resin tube 6, and then the piston rod of the cylinder 8 is contracted and the fiber-reinforced resin tube 6 is moved in the direction indicated by the arrow. Push out in direction B and rotate mold 5
It is released from the mold.

Problems to be Solved by the Invention According to the conventional configuration described above, in order to release the fiber reinforced resin tube 6 from the rotary mold 5, the rotary mold 5 is removed from the drive shaft and placed on the bed 7, It takes time and effort to attach and detach the mold 5, and space for the bed 7 must be secured. More nails 9
Since the fiber-reinforced resin tube 6 is forcibly extruded, the ends and inner peripheral surface of the fiber-reinforced resin tube 6 are easily damaged.

Means for Solving the Problems In order to solve the above-mentioned problems, the fiber-reinforced resin pipe manufacturing apparatus of the present invention is provided with a rotary main body for forming a fiber-reinforced resin pipe whose base end is fixed to a drive shaft. A housing having a diameter smaller than that of the rotary body is provided at the tip of the rotary body, a feeding port is formed at an appropriate position on the outer peripheral surface of the housing, and a reel wound with a coil for covering the rotary body is rotatably disposed within the housing. A winding drive device is provided for winding the coil by rotating the reel in a state where there is no tensile force of the tension drive device, and a first engaging portion is formed on one side edge of the coil, and a first engagement portion is formed on the other side edge. A second engaging portion that can be engaged with the engaging portion is formed, and the first portion of the coil that has been fed out is formed at a location opposite to the feeding opening of the housing.
A glass fiber impregnated with a resin liquid is provided with an engaging tool for engaging the engaging part with a second engaging part of an adjacent part that has already been fed out, and supplies the glass fiber impregnated with a resin liquid onto a coil wound around a rotary main body. It is equipped with a supply device.

According to this configuration, when the coil is fed out from the feeding port by the tension drive device, the first engaging portion of the drawn out portion of the coil engages the second engaging portion of the adjacent portion that has already been fed out by the engaging metal fitting. When the coil is engaged with the mating portion and the coil is fully extended, the outer circumferential surface of the rotary main body can be completely covered with the coil. In such a state, after winding the resin liquid-impregnated glass fiber around the rotary main body to form a fiber-reinforced resin tube, the tensile force of the tension drive device is removed and the coil is wound by the winding drive device. A fiber-reinforced resin tube is pulled out from the rotary main body.

The upper side of the figure shows the state in which the coil 36 is being wound around the rotary main body 13 before manufacturing the fiber reinforced resin pipe 6, and the lower side of the figure shows the state immediately after manufacturing the fiber reinforced resin pipe 6. Fiber-reinforced resin pipes 6 are manufactured alternately using two rotary main bodies 13.
First, as shown in FIG. 8a, while the coil 36 is wound around the reel 35, the piston rod of the tension cylinder device 42 is extended and the motor 34 is activated. Then, the reel 35 is rotated in the direction of arrow E, and the coil 36 wound around the reel 35 is fed out from the feeding opening 33. As shown in FIG. 9, the first engaging portion 36A of the unwound portion of the coil 36 is forcibly pressed against the second engaging portion 36B of the adjacent portion supported by the engaging fitting 40, and both The engaging portions 36A, 36B are fitted together. Once the coil 36 has been wound around the entire outer peripheral surface of the rotary body 13 as shown in FIG. 8b, the flanged ring 95 is attached to the base end of the rotary body 13 as shown in FIG. 8c. The tape supply device 1 is fitted onto the outside, and the support shaft 39 is held by the bearing box 50 of the bearing device 15, and is positioned at the left end in FIG.

As a result, the tape 63 is wound onto the coil 36. Next, after wrapping the tape 63, the eighth
As shown in FIG.
is pulled out, the end of the glass fiber 2 is attached to the ring 95, and the rotary main body 13 is rotated by the drive shaft 11.
is rotated in the direction of arrow E, and the supply device 1
9 in the direction of arrow C. As a result, the resin liquid-impregnated glass fiber 2 is wound around the ring 95 and the coil 36. Next, as shown in FIG. 8e, when the resin liquid 68 is cured and the tape 63 is integrated with the glass fiber 2 to form the fiber-reinforced resin pipe 6, the piston rod of the bearing cylinder device 49 of the bearing device 15 is removed. The bearing box 50 is separated from the support shaft 39 by shrinking. Next, the moving vehicle cylinder device 55 of the rotary support device 16 moves the moving vehicle 53 located on the lower surface 52B of the cam plate 52 to above the upper surface 52A, and the supporting roller 54 is moved as shown in the lower side of FIG. The coil 36 is brought into contact with the tip of the rotary body 13 to support the tip of the rotary body 13. Next, the piston rod of the tensioning cylinder device 42 is reduced, and the reel 35 is rotated in the direction of arrow F by the winding motor 34. Then, the coil 36 is wound onto the reel 35, and the fiber-reinforced resin tube 6 is moved together with the coil 36 in the direction of arrow C.
It is pulled out from the rotary main body 13. Note that since the tip of the rotary body 13 is bent to some extent, the fiber-reinforced resin tube 6 can be easily pulled out by passing between the tip of the rotary body 13 and the support roller 54. The fiber-reinforced resin pipe 6 that has been pulled out is placed on a lifting platform 59. Next, by removing the ring 95, the fiber reinforced resin pipe 6 shown in FIG. 8f can be obtained.

In the first embodiment described above, a single coil 36 was used, but as shown in FIG. 36 may be used (second embodiment).

Effects of the Invention As described above, according to the present invention, when the coil is fed out from the feeding port by the tension drive device,
The first engaging part of the part of the coil that has been paid out is engaged by the second engaging part of the adjacent part that has already been paid out by the engaging tool, and when the coil is all paid out, the coil The outer peripheral surface of the rotary main body can be completely covered. In such a state, after winding the resin liquid-impregnated glass fiber around the rotary main body to form a fiber-reinforced resin tube, the tensile force of the tension drive device is removed and the coil is wound by the winding drive device. A fiber-reinforced resin tube is pulled out from the rotary main body.
Therefore, it is not necessary to remove the rotary type main body as in the past, which saves time and effort, and there is no need for a rotary type mounting bed, which was required in the past. Furthermore, since the fiber-reinforced resin tube is drawn out indirectly through the coil, the fiber-reinforced resin tube is not damaged.
