DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus for manufacturing a fiber-reinforced resin pipe by winding glass fiber impregnated with a resin liquid around a rotary main body.

BACKGROUND ART Conventionally, as shown in FIG. 9, 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 attached to the head 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 above-described conventional structure, the tip of the rotary mold 5 is supported by a fixed bearing, so the fiber reinforced resin tube 6 cannot be removed from the rotary mold 5 as it is. Therefore, remove the rotary mold 5 from the drive shaft and place it on the bed 7.
After that, the fiber reinforced resin tube 6 is released from the rotary mold 5. Therefore, it takes time and effort to attach and detach the rotary mold 5, and space in the bed 7 must be secured. Furthermore, the fiber-reinforced resin tube 6 is easily damaged when it is attached and detached.

The operation of the above configuration will be explained below. In addition, the first
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 housing 32 is rotated in the direction of arrow E by the reel drive motor 29. Then, the reel 35 is also rotated in the same direction, and the coil 36 wound around the reel 35 is fed out from the feeding opening 33. As a result, the guide rod 37 at the tip of the coil 36 moves in the direction of arrow D while being guided by the guide rail 27.
The coil 36 is wound around the rotary main body 13. At this time, the tension motor 34 applies a rotational force in the direction of arrow F to the reel 35 to apply appropriate tension to the coil 36 to prevent the coil 36 from loosening. After the coil 36 is wound around the entire outer circumference of the rotary main body 13 as shown in FIG. Fit the bearing box 50 of the bearing device 15
The support shaft 39 is held by the spindle 39, and the tape 63 is pulled out from the tape supply device 18 located at the left end in FIG. While rotating the mold body 13 in the direction of arrow F, the screw shaft 20
The tape supply device 18 is moved in the direction of arrow C by the rotation. As a result, the tape 63 is wound onto the coil 36. Next, after wrapping the tape 63, as shown in FIG. 8d, the glass fiber 2 is pulled out from the resin liquid-impregnated glass fiber supply device 19 located at the left end in FIG. Installation, drive shaft 11
As a result, the rotary main body 13 is rotated in the direction of arrow E, and the supply device 19 is moved 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 bearing device 15
The piston rod of the bearing cylinder device 49 is reduced to separate the bearing box 50 from the support shaft 39. Next, the lower surface 52 of the cam plate 52 is moved by the moving vehicle cylinder device 55 of the rotating support device 16.
Move the moving vehicle 53 located above B to above the upper surface 52A, bring the support roller 54 into contact with the tip of the rotary main body 13 via the coil 36 as shown in the lower part of FIG. 13 is supported. Next, the housing 32 is rotated in the direction of arrow F by the reel drive motor 29. Then, the coil 36 is wound onto the reel 35, and the coil 3
6, the fiber-reinforced resin tube 6 is moved in the direction of arrow C and 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 drawn-out fiber reinforced resin pipe 6 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.

Effects of the Invention As described above, according to the present invention, after the fiber-reinforced resin tube is formed, the bearing drive device moves the bearing box away from the support shaft at the tip of the rotary mold body, so that the rotary mold body can be supported on a cantilever. You can simply wind the coil onto a reel using the reel drive device without removing the rotating body from the drive shaft.
The fiber-reinforced resin tube can be pulled out from the rotary main body. Therefore, there is no need for the time and effort required to attach and detach the rotary type main body as in the prior art, and there is no need for a rotary type mounting bed. Also, if the rotary body is cantilevered as shown above,
When pulling out the fiber-reinforced resin pipe, the rotating body may swing and may not be pulled out smoothly.
According to the present invention, it is possible to prevent the rotary body from swinging by moving the vehicle using the vehicle drive device and bringing the support roller into contact with the lower surface of the tip of the rotary body. Therefore, the fiber-reinforced resin pipe can be smoothly pulled out from the rotary main body.
