It can comprise so that it can approach and separate with respect to the radial direction of the said winding roll.

  Thereby, for example, when the winding of the pipe rehabilitation member proceeds and the diameter of the winding roll increases, the bending portion and the winding roll can be moved because the radial position of the bending portion can be moved. Interference can be prevented.

  In each of the manufacturing apparatuses, the fitting portion includes at least one upper roller disposed on the upper side of the reinforcing member and at least one lower roller disposed on the lower side of the belt-shaped member. The upper roller and the lower roller are configured to be close to and away from the radial direction of the take-up roll according to the take-up amount of the conduit rehabilitation member that is taken up by the take-up roll. can do.

  Thereby, for example, when the winding of the pipe retreading member proceeds and the diameter of the winding roll becomes large, the radial position of the fitting portion can be moved, so the fitting portion and the winding roll Can be prevented from interfering with each other.

  The fitting unit 6 includes a housing 61, a plurality of rollers 62 to 65 accommodated in the housing 61, and a moving mechanism 66 that moves the rollers 62 to 65. The casing 61 is formed to extend radially outward with the take-up roll 71 as a reference. Hereinafter, unless otherwise specified, the terms “radial direction” and “circumferential direction” are based on the winding roll 71.

  A pair of first large roller 62 and first small roller 63 disposed on the upstream side are disposed inside the casing 61, and the first large roller 62 is more than the first small roller 63. Is also arranged radially outward. As shown in FIG. 7, the first large rollers are arranged at a predetermined interval and are connected by a rotation shaft 69. Each first large roller 62 is inserted between the side plate portions 21 and 22 of the reinforcing member 2 and the connecting portion 23 so as to press the reinforcing member 2 from the outside in the radial direction. On the other hand, the length of the first small roller 63 in the axial direction is formed larger than the width between the ribs 12 so as to support the belt-like member 1 on the radially inner side.

  The belt-shaped member 1 and the reinforcing member 2 are configured to pass between the first large roller 62 and the first small roller 63. As a result, the belt-like member 1 and the reinforcing member 2 are pressed by both rollers 62 and 63, and the reinforcing member 2 is fitted between the ribs 12 of the belt-like member 1.

<3. Manufacturing Method for Pipe Rehabilitation Member>
Next, the operation of the manufacturing apparatus for the pipe rehabilitation member 100 configured as described above, that is, the method for manufacturing the pipe rehabilitation member 100 will be described.

  First, the first roll 31 is rotationally driven to feed out the belt-like member 1, and the second roll 41 is also rotationally driven to pay out the reinforcing member 2. Then, the reinforcing member 2 fed out from the second roll 41 is conveyed linearly to the bending part 5, and bending bends are given in the bending part 5. That is, the reinforcing member 2 is guided straight by the first and second upper rollers 51 and 52 of the bending portion 5 and the lower roller 53 so that the reinforcing member 2 moves straight in the horizontal direction, but the bending member disposed on the downstream side thereof. The roller 54 is pressed downward and bent downward. Thereby, the metal reinforcing member 2 is bent so as to draw an arc along the longitudinal direction, and is conveyed to the fitting portion 6.

  On the other hand, the belt-like member 1 fed out from the first feeding roll passes linearly below the reinforcing member 2 and contacts the lower end side of the reinforcing member 2 while being guided by the guide portion 8 below the bending portion 5. To do. And the reinforcement member 2 and the strip | belt-shaped member 1 are guided to the fitting part 6 in the state which contacted. In the fitting portion 6, the reinforcing member 2 and the belt-like member 1 are pressed between the large rollers 62 and 64 and the small rollers 63 and 65 from the inside and the outside in the radial direction. Thereby, the reinforcing member 2 is fitted between the adjacent ribs 12 of the belt-shaped member 1, and the pipe line rehabilitation member 100 is formed. At this time, the reinforcing member 2 is pushed between the ribs 12 while being pressed in the width direction. And as shown in FIG. 1, the upper end part of each side-plate part 21 and 22 of the reinforcement member 2 latches to the retaining part 13 provided in the front-end | tip of the rib 12 from the lower side, and, thereby, the reinforcement member 2 Is prevented from coming out of the belt-like member 1.

  Thus, the pipe rehabilitation member 100 that has passed through the fitting portion 6 is wound around the winding roll 71 that is rotationally driven while being pulled downward.

  The pipe rehabilitation member 100 manufactured as described above is applied to an existing pipe as follows. That is, while being fed from the take-up roll 71, it is supplied spirally in the existing pipe. Then, the projecting member 14 of the first end 101 of the preceding pipe rehabilitation member 100 and the locking groove 15 of the second end 112 of the subsequent pipe rehabilitation member 100 that is delayed in circulation are sequentially joined to each other. A cylindrical rehabilitation pipe is formed in the pipe line.

<4. Features>
(1) Since the reinforcing member 2 is fed out linearly and conveyed to the fitting portion 6 and fitted between the ribs 12 of the belt-shaped member 1, the direction of the reinforcing member 2 does not change during conveyance. Therefore, the reinforcing member 2 which is heavy and has high rigidity can be stably conveyed. For example, if the reinforcing member 2 is transported along a curved path, the reinforcing member 2 may be displaced from the path or the transport speed may vary, but such a problem is caused by the above configuration. Can be prevented.

(2) Since the reinforcing member 2 is formed of a metal material, and the rigidity of the reinforcing member 2 and the belt-like member 1 is different, it is not easy to fit the reinforcing member 2 into the belt-like member 1 smoothly. On the other hand, in this embodiment, before the reinforcing member 2 is fitted into the belt-like member 1, a curl that bends in an arc shape is applied to the reinforcing member 2. Thereby, the reinforcing member 2 can be smoothly fitted into the band-shaped member 1.

(3) Since the rollers 62 to 65 can be moved in the radial direction in the fitting portion 6, for example, the winding of the pipe rehabilitation member 100 in the winding roll 71 proceeds, and the diameter of the winding roll 71 is large. When this happens, the rollers 62 to 65 of the fitting portion 6 are moved radially outward to prevent interference with the take-up roll. Such movement of the rollers 62 to 65 can be controlled in various ways. For example, the diameter of the take-up roll 71 can be measured, and the rollers 62 to 65 can be automatically moved in accordance with this measurement. Alternatively, the rollers 62 to 65 can be manually moved.

<5. Modification>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. Hereinafter, modified examples will be described. However, the following modifications can be combined as appropriate.

<5-1>

For example, the belt-shaped member 1 can be fed out as it is after being molded from resin. And the reinforcing member 2 can be similarly extended without using a roll.

<5-2>
The form of the band-shaped member 1 and the reinforcing member 2 is not particularly limited. For example, for the band-shaped member 1, a pair of ribs 12 into which at least the reinforcing member 2 is fitted may be formed on one surface of the substrate 11. Therefore, in addition to the number of ribs 12 and retaining portions 13 and 17, the configuration of the projecting member 14 and the locking groove 15 for connection can be appropriately set as necessary.

  Further, the reinforcing member 2 only needs to be composed of at least a pair of side plate portions 21 that contact the ribs 12 and a connecting portion 23 that connects these side plate portions 21 and 22. Therefore, the configuration of the connecting portion 23 can be changed as appropriate, and for example, as shown in FIG. 8, it can be a connecting portion having a U-shaped cross section.

<5-3>
The bending part 5 can have various configurations as long as the bending member 5 can be provided with the bending member, and the number of rolls is not particularly limited. Moreover, pressing with a roll like the said embodiment is an example, and you may press other than a roll. The bending unit 5 can also be configured so that the roll can be moved in the radial direction in the same manner as the fitting unit 6, and the movement can be controlled in the same manner as the fitting unit 6.

<5-4>
The configuration of the fitting portion 6 is not particularly limited as long as the band-shaped member 1 and the reinforcing member 2 are sandwiched by a roll or the like, and the reinforcing member 2 may be pushed between the ribs 12. Therefore, the shape and number of rolls are not particularly limited, and can be appropriately changed according to the cross-sectional shape of the reinforcing member 2. Moreover, the structure which moves the fitting part 6 to radial direction is not specifically limited, Various structures are possible.
