DETAILED DESCRIPTION OF THE INVENTION

[0031] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [First embodiment of the invention] Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

[0032] First, the configuration of this embodiment will be described. As shown in Fig. 1, a solid reinforcement conveying device 10 for a cylindrical body of this embodiment is a conveying device for conveying the solid reinforcement materials B (described later) to an opening 2 of the cylindrical body 1 and filling the solid reinforcement materials B from the opening 2 into the cylindrical body interior 3 when filling the interior 3 of the cylindrical body with a plurality of solid reinforcement materials B (described later) to reinforce, for example, a cylindrical pole equipped with a mobile phone base station antenna (hereinafter referred to as cylindrical body 1). Note that the use of the cylindrical body 1 is not limited to installing a mobile phone base station antenna, and it may be used for any appropriate purpose.

[0033] The cylindrical body 1 is a generally elongated columnar body having a hollow portion (hereinafter referred to as the cylindrical body interior 3) formed approximately at the center along the longitudinal direction. At least one longitudinal end forms an opening 2 to the cylindrical body interior 3, and this opening 2 allows multiple solid reinforcing bodies B to be filled into the cylindrical body interior 3. The cylindrical body 1 of this embodiment is erected in a generally vertical direction with the opening 2 at the top. In this embodiment, the cylindrical body 1 has a generally cylindrical shape, the cylindrical body interior 3 is also formed in a generally cylindrical shape, and the opening 2 is an approximately circular opening. However, this is not limited thereto. The cylindrical body may have a shape other than a generally cylindrical shape, such as a rectangular tube shape or an elliptical shape, and the cylindrical body interior 3 may also have a shape other than a generally cylindrical shape, such as a rectangular tube shape, and the opening may also be formed in a shape other than a generally circular shape, such as a square tube shape. Furthermore, in this embodiment, the cylindrical body 2 is in an upright position on the ground, but this is not limited to this, and it may be in a position other than upright, such as being placed sideways on the ground or being held at an angle.

[0034] Furthermore, a predetermined number of solid reinforcing materials B are filled into the interior 3 of the cylindrical body, and are formed to be at least smaller in size than the diameter of the interior 3 of the cylindrical body. In this embodiment, solid reinforcing materials B are used, which are roughly spherical bodies made of a core of FRP resin (or other suitable resins) coated with a polyurethane resin, and each of the solid reinforcing materials is able to move independently without sticking to each other. Polyurea resin is a resin having a urea bond formed by a chemical reaction between isocyanate and an amino group, for example. One example of a polyurethane resin is formed by reacting polyisocyanate with a polyamine. By using such solid reinforcing materials B, multiple lightweight yet strong solid reinforcing materials B can be filled into the interior 3 of the cylindrical body, thereby providing effective strength reinforcement.

[0035] In this embodiment, the solid reinforcing material B is formed into a substantially spherical body. However, in this embodiment, the substantially spherical shape is not limited to a perfect sphere, and may include spheres and ellipsoids that exhibit surface irregularities or sphericity resulting from the production process. Furthermore, the solid reinforcing material B may be formed into other shapes, such as a polygonal solid or an irregular solid, but a substantially spherical shape is particularly preferable due to its enhanced reinforcing effect. The shape and size of the solid reinforcing material B may be determined appropriately depending on the shape and size of the opening 2 of the cylindrical body 1 and the interior 3 of the cylindrical body to be filled. Furthermore, the material of the solid reinforcing material B is not limited to the polyurethane resin coating described above, and any other suitable material can be selected. However, the polyurethane resin coating is particularly preferred due to its light weight and high strength, as described above.

[0036] The solid reinforcement material conveying device 10 for a cylindrical body of this embodiment is configured to convey a plurality of solid reinforcement materials B from below upward and fill the interior 3 of the cylindrical body through the opening 2. In more detail, this solid reinforcement material conveying device 10 for a cylindrical body is configured to include an upward conveying device 20 as upward conveying means for conveying a plurality of solid reinforcement materials B from below upward, a lateral conveying section 30 as lateral conveying means for conveying the plurality of solid reinforcement materials B conveyed upward by this upward conveying device 20 in a substantially lateral direction, and a filling section 40 as filling means for filling the plurality of solid reinforcement materials B from the opening 2 into the interior 3 of the cylindrical body after being conveyed by this lateral conveying section 30.

[0037] Furthermore, the solid reinforcement material transport device 10 for cylindrical bodies of this embodiment is configured to be separable, so that it can be divided into multiple segments according to the distance to transport multiple solid reinforcement materials B and adjusted to the appropriate length for use. Here, the upper transport device 20 is configured to be separable into multiple segments 50, 60, 70, and 80, which can be combined appropriately to transport the solid reinforcement materials B upward to a predetermined height. Here, the segments 50, 60, 70, and 80 are configured to be connected alternately left and right from bottom to top.

[0038] Depending on the situation, the segments may be connected alternately left and right, or may be connected in other ways, such as by connecting one segment to the other in a stepped manner. Furthermore, segments 50, 60, 70, and 80 may be further joined together to transport the solid reinforcement material B upward to even higher locations. In this embodiment, the horizontal conveying device 30 and the filling unit 40 are not configured to be separable, but this is not a limitation. These may also be separable, allowing the horizontal length to be adjusted, or the length of the filling portion to be changed.

[0039] As shown in FIGS. 2 to 7 , the upper conveying device 20 is configured by connecting multiple segments 50, 60, 70, and 80, as described above. Each segment 50, 60, 70, and 80 has conveyor belts 51, 71, and 81 (the conveyor belt of segment 60 is not shown) for conveying the solid reinforcement material B vertically, mounting pieces 53, 73, and 83 (the mounting pieces of segment 60 are not shown) attached at equal intervals to the conveyor belts 51, 71, and 81 to place and transport the solid reinforcement material B, and motors 52, 72, and 82 (the motor of segment 60 is not shown) as rotational drive units. Note that, here, two motors 52, 72, and 82 are provided on the top and bottom of each segment, but this is not limited thereto. One motor per segment may be provided, or three or more motors per segment may be provided. Furthermore, the number of motors provided may vary from segment to segment. Furthermore, if the motor has a high output, only one motor may be provided for any of the divided bodies, and all of the divided bodies may be driven by that one motor.

[0040] 2 and 3, the lowermost divided body 50 is provided with an inflow passage 25 for the solid reinforcing material B, and this inflow passage is inclined so that the solid reinforcing material B is successively taken into the divided body 50, placed on the placing piece 53, and transported upward. A shutter 24 is provided at the location where the inflow passage 25 of the divided body 50 is attached, and the shutter 24 is closed when the transport device 10 is not in use.

[0041] 4 and 5, at the connection portions between the divided bodies 50, 60, 70, and 80 (here, the connection portion between the divided bodies 70 and 80 is shown), the solid reinforcing material B that has been placed on the mounting piece 73 and transported upward is pushed out toward the next divided body 80 by the pushing portion 74 provided at a position above the divided body 70, and is placed on the next mounting piece 83. In this embodiment, the pushing portion 74 is composed of a rotating roller fixed to that location, and when the solid reinforcing material B that has been placed on the mounting piece 73 and transported upward by the conveyor belt 71 abuts against the pushing portion 74, the movement of the conveyor belt 71 presses the solid reinforcing material B against the pushing portion 74, and it is pushed out toward the divided body 80 (leftward in FIGS. 4 and 5).

[0042] In addition, in this embodiment, as shown in Figure 4, the motors 52, 72, and 82 of each divided body 50, 60, 70, and 80 are connected by gears 75 and 85, respectively (gears of the other divided bodies are not shown), and are configured so that each drive speed is the same.

[0043] Furthermore, the solid reinforcing material B transported to a position above the uppermost divided body 80 is pressed against the extrusion section 84 and extruded in the direction of the lateral transport section 30 (to the right in FIGS. 6 and 7).

[0044] The lateral conveying section 30 is made up of a bellows-shaped cylindrical member, and is attached so as to be inclined downward from the divided body 80 so that the solid reinforcing material B flows naturally in the direction of the filling section 40.

[0045] The filling unit 40 is fixed to the cylindrical body 1 so as to cover the opening 2 of the cylindrical body 1, and a sensor 91 (described later) protrudes below the filling unit 40. A support unit 45 is formed laterally from the filling unit 40, and is configured to support the upper conveying device 20 on the cylindrical body 1.

[0046] In this embodiment, a control unit (not shown) is provided to control the motors serving as drive devices for each of the divided bodies 50, 60, 70, and 80 of the upper conveying device 20, thereby driving each of them at the same speed. This embodiment also includes a solid reinforcement material filling stopper means that can stop the filling of the solid reinforcement material B from entering the interior 3 of the cylindrical body 1 when the solid reinforcement material B filled through the opening 2 nearly fills the interior 3 of the cylindrical body 1. This solid reinforcement material filling stopper means includes a sensor 91 as a detection means and a control unit as a stopper means. Here, the sensor 91 is a contact sensor that protrudes downward from the filling section 40 and is positioned along the edge of the opening 2 of the cylindrical body 1. When the solid reinforcement material B comes into contact with this sensor 91, a contact signal is sent to the control unit, and in response, the control unit automatically sends a motor stop signal. When the motor stop signal is sent, the motors of the divided bodies 50, 60, 70, and 80 are stopped, thereby halting the supply of the solid reinforcement material B.

[0047] In this embodiment, a forced stopper device 90 is provided as second stop means. As shown in Figures 8 and 9, this stopper device 90 is disposed near the filling section 40 and has a stopper 92 that is generally L-shaped in cross section. This stopper 92 forcibly stops the filling of the solid reinforcing material B from the filling section 40 into the cylindrical body interior 3, and is normally biased diagonally upward (upper right in Figure 8) by a biasing means 93 such as a spring and held by an opening / closing member connected to an opening / closing motor 94, as shown in Figure 8.

[0048] When the solid reinforcing material B is nearly full inside the cylindrical body 3 and the sensor 91 detects that the solid reinforcing material B has reached the full capacity and issues a signal indicating that the solid reinforcing material B is nearly full, but the control unit is unable to automatically stop the motor, an operator can press the stop button on the control unit to issue a forced stop signal, activate the open / close motor 94, release the hold on the open / close member, remove the biasing means 93, and, as shown in Fig. 9, the stopper 92 rotates around the upper pivot axis due to gravity, with the lower part moving diagonally downward (to the lower left in Fig. 9) and blocking the flow path of the filling unit 40. This prevents the solid reinforcing material B from forcibly flowing in through the opening 2, and prevents any more solid reinforcing material B from being filled into the cylindrical body 3.

[0049] In addition to the above-mentioned cases where the motor cannot be stopped, the system may be configured so that the sensor 91 as detection means detects that the container is nearly full, the control unit as stop means stops the motor, and the stopper 92 is operated by an operator. Also, the system may be configured so that the stopper 92 is automatically activated when the sensor 91 detects that the container is nearly full (the forced stopper device 90 acts as stop means). Furthermore, the system may be configured so that the control unit automatically stops the motor and activates the stopper 92 when the sensor 91 detects that the container is nearly full (both the control unit and the forced stopper device 90 act as stop means).

[0050] 10 to 13 is provided as a separate component constituting the solid reinforcement material transport device 10 for a cylindrical body, and in the solid reinforcement material transport device 10 for a cylindrical body, after the solid reinforcement material B is filled into the cylindrical body interior 3, the solid reinforcement material B filled into the cylindrical body interior 3 is pressurized from the opening 2 side using the pressurizing jig 100 to perform a pressurizing step in which the solid reinforcement material B is made difficult to move within the cylindrical body interior 3, both between the solid reinforcement material B and each other and between the solid reinforcement material B and the cylindrical body interior 3. This further increases the strength of the cylindrical body 1.

[0051] 10 to 13, the pressing jig 100 of this embodiment has a first driving member 101 and a second driving member 102. The second driving member 102 is provided with an elongated hole 109, and the first driving member 101 is provided with a protrusion 103, which is inserted into the elongated hole 109, so that the first driving member 102 and the second driving member 102 can slide and rotate relative to each other with the protrusion 103 as an axis.

[0052] The pressurizing jig 100 also has a first operating unit 106 and a second operating unit 108. Of these, the first operating unit 106 is an operating unit for operating the first driving member 101 and the second driving member 102 to hold and fix the pressurizing jig 100 to the cylindrical body 1 with the first driving member 101 and the second driving member 102. The second driving member 102 is an operating unit for pressurizing the solid reinforcing material B filled inside the cylindrical body 3.

[0053] To explain in detail how the pressing jig 100 is held and fixed to the cylindrical body 1, the first operating part 106 is a generally rod-shaped member, and a flange-shaped locking part 107 is provided at the tip of the first operating part 106. A handle is provided at the rear end of the first operating part 106 for rotating it along the axial direction. The first operating part 106 is configured to be installed in a generally horizontal direction so that the locking part 107 passes through the cylindrical part 105 fixed to the second driving member 102 and abuts on the locked part 104 fixed to the first driving member 101. The first operating part 106 and the cylindrical part 105 are configured to be threaded together (thread grooves and the like are not shown). By rotating the first operating part 106 in one axial direction, a force is applied in a direction that moves the cylindrical part 105 toward the rear end around the protrusion 103, and at the same time, the locking part 107 presses the locked part 104 in the direction opposite to the rear end. 12 and 13, the first driving member 101 and the second driving member 102 move in the opening direction around the protrusion 103, and both are pressed against the inner wall of the cylindrical body 1. This causes the pressing jig 100 to be held and fixed to the cylindrical body 1.

[0054] Regarding the application of pressure to the solid reinforcing material B filled inside the cylindrical body 3, the second operating part 108 is a generally rod-shaped member, and the generally disk-shaped pressure member 110 is attached to the tip of the second operating part 108 by screws. A handle is provided at the rear end of the second operating part 108 for rotating it along the axial direction. The second operating part 108 is screwed onto the second driving member 102 so that it passes from above to below. By rotating the second operating part 108 in one axial direction, the pressure member 110 moves downward relative to the second driving member 102. A short, roughly cylindrical pressure plate 120 is placed on top of the filled solid reinforcing material B, and by pressing the pressure plate 120 downward with the pressure section 110 moving from above to below, the filled solid reinforcing material B is pressurized with a predetermined pressure, causing the solid reinforcing materials B to adhere closely to each other and to the inside of the cylindrical body 3, making it difficult for them to move together, and as a result, creating a state in which the strength of the cylindrical body 1 is further increased.

[0055] After pressing, the pressing jig 100, including the pressing plate 120, may be removed from the cylindrical body 1 and used to pressurize the next cylindrical body 1. Alternatively, only the pressing plate 120 or the pressing jig 100 may be left installed on the cylindrical body 1.

[0056] Furthermore, the pressing jig used in the pressing step is not limited to the pressing jig 100 described above, and other pressing jigs or pressing devices may be used to perform similar pressing. For example, a pressing jig 100A as shown in Fig. 14 may be used. This pressing jig 100A includes a base portion 102A, a driving member 101A provided on the upper portion thereof, a pressing unit 110A disposed below the base portion 102A, and operation units 103A and 104A for operating these units.

[0057] More specifically, this pressurizing jig 100A has a base portion 102A that is generally circular in plan view and is provided with a plurality of drive members 101A (four in this example) that are generally fan-shaped in plan view. The top surface of the base portion 102A is configured to slope downward from the center to the outside, and by rotating a first operating unit 103A provided on the drive member 101A in one direction using a jig or the like, the drive member 101A moves diagonally downward and outward along the slope of the base portion 102A. The drive members 101A of the pressurizing jig 100A are inserted into the interior 3 of the cylindrical body 1 through the opening 2 of the cylindrical body 1, and the first operating units 103A are rotated to move the plurality of drive members 101A outward relative to the base portion 102A (in the direction of the arrows in FIG. 14). This causes the plurality of drive members 101A to be pressed against the inner wall of the cylindrical body 1, thereby holding and fixing the pressurizing jig 100A to the cylindrical body 1.

[0058] Further, a pressure applying unit 110A for pressing the solid reinforcing material B is disposed below the base portion 102A, and a rod-shaped second operating unit 104A is attached to the upper portion of this pressure applying unit 110A. The second operating unit 104A extends above the driving member 101A through an insertion hole 105A provided in the center of the base portion 102A. After the driving member 101A is pressed against the inner wall of the cylindrical body 1 to hold and fix the pressing jig 100A to the cylindrical body 1, the second operating unit 104A is operated with a jig or the like to move the pressure applying unit 110A downward, and the pressure applying unit 110A applies a predetermined pressure to the solid reinforcing material B filled in the cylindrical body interior 3, thereby creating a state in which the solid reinforcing materials B are less likely to move within the cylindrical body interior 3, both between themselves and the cylindrical body interior 3, and as a result, the strength of the cylindrical body 1 is further increased.

[0059] After pressing, the pressing jig 100A may be removed from the cylindrical body 1 and used to pressurize the next cylindrical body 1, similar to the above-described pressing jig 100. It is also possible to leave the pressing jig 100A installed on the cylindrical body 1 as it is.

[0060] Furthermore, the pressure applying jig is not limited to the above-described pressure applying jigs 100 and 100A, which apply pressure by holding the jig on the inside (inner wall) of the cylindrical body 1, but may be one that applies pressure by holding and fixing the jig from the outside of the opening 2 of the cylindrical body 1 (for example, by clamping it at multiple points), although this is not shown in the drawings. Also, the driving means for moving the pressure applying part may be any means that moves the pressure applying part by an appropriate force, such as manual, electric, or hydraulic.

[0061] Next, a method for transporting a solid reinforcement material for a cylindrical body using the apparatus 10 for transporting a solid reinforcement material for a cylindrical body according to this embodiment will be described.

[0062] First, in a preparation step, the divided bodies 50, 60, 70, and 80 are assembled to a predetermined height (a length slightly higher than the cylindrical body 1) to match the cylindrical body 1. The cylindrical body 1 and the upper conveying device 20 are connected by a support part 45. An inlet passage 25 is attached to the bottom divided body 50, a lateral conveying part 30 is attached to the top divided body 80, a filling part 40 is attached to the lateral conveying part 30, and the filling part 40 is attached to the opening 2 of the cylindrical body 1.

[0063] Once preparations are complete, the conveying step is carried out. Here, the solid reinforcing material B is taken in from the lowest divided body 50, conveyed to the top divided body 80 in an upward conveying step by the upward conveying device 20, conveyed to the filling section 40 in a horizontal conveying step by the horizontal conveying section 30, and then poured from the filling section 40 into the opening 2 of the cylindrical body 1 in the filling step, thereby filling the interior 3 of the cylindrical body with the solid reinforcing material B.

[0064] The solid reinforcement material filling stopper process includes a detection process using a sensor 91 that detects that the interior 3 of the cylindrical body is nearly full with the solid reinforcement material B filled through the opening 2, and a stop process in which a control unit stops the motor to stop the filling of the solid reinforcement material B into the interior 3 of the cylindrical body when the detection process detects that the interior 3 is nearly full, thereby safely and reliably filling the interior 3 of the cylindrical body with the solid reinforcement material B. The solid reinforcement material filling stopper process may include a stopper device 90 that forcibly stops the inflow of the solid reinforcement material B instead of or in addition to stopping the motor.

[0065] In this embodiment, a pressurizing step is then performed. Specifically, a pressurizing plate 120, as shown in FIGS. 10 to 13, is inserted into the interior 3 of the cylindrical body and placed on top of the filled solid reinforcing material B. The pressurizing jig 100 is attached to the opening 2 of the cylindrical body 1. The first operating unit 106 is operated to move the first driving member 101 and the second driving member 102 in the opening direction, thereby holding and fixing them to the inner wall of the cylindrical body 1. Then, the second operating unit 108 is operated to move the pressurizing unit 110 downward and press the pressurizing plate 120, thereby pressurizing the solid reinforcing material B with a predetermined pressure, thereby creating a state in which the solid reinforcing materials B are difficult to move relative to each other and between the solid reinforcing material B and the interior 3 of the cylindrical body. The pressurizing jig 100 and the pressurizing plate 120 are then removed from the cylindrical body 1, completing the reinforcement of the cylindrical body 1 with the predetermined strength.

[0066] The pressurizing step may also be performed using a pressurizing jig 100A as shown in FIG. 14 . Here, the pressurizing unit 110A of the pressurizing jig 100A is inserted into the interior 3 of the cylindrical body 1 through the opening 2 and placed on top of the filled solid reinforcing material B. The drive member 101A of the pressurizing jig 100A is also inserted into the interior 3 of the cylindrical body 1 through the opening 2 of the cylindrical body 1. Then, the first operating unit 103A is operated to move the drive member 101A in a direction opening outward relative to the base unit 102A, thereby holding and fixing it to the inner wall of the cylindrical body 1. Then, the second operating unit 104A is operated to move the pressurizing unit 110A downward to apply a predetermined pressure to the solid reinforcing material B, thereby creating a state in which the solid reinforcing material B is less likely to move relative to each other and between the solid reinforcing material B and the interior 3 of the cylindrical body 1. The pressurizing jig 100A is then removed from the cylindrical body 1, completing the reinforcement of the cylindrical body 1 with the predetermined strength.

[0067] Furthermore, the pressurizing step may be performed using another pressurizing jig. For example, the pressurizing jig may be held by clamping the opening 2 of the cylindrical body 1 with holding parts at multiple locations, and then a hydraulic device may be used to move a pressurizing part provided in the center downward to pressurize the solid reinforcing material B with a predetermined pressure, thereby creating a state in which the solid reinforcing material B is less likely to move relative to each other and between the solid reinforcing material B and the cylindrical body interior 3. In this case, too, the pressurizing jig is then removed from the cylindrical body 1, and reinforcement of the cylindrical body 1 with the predetermined strength is completed. [Embodiment 2 of the Invention] Next, a second embodiment of the present invention will be described with reference to Fig. 15.

The drone 1511 is remotely controlled by an operating device 1513. Sixteenth Embodiment Next, a sixteenth embodiment of the present invention will be described with reference to Fig. 29. A solid reinforcement material transport device 1610 for a cylindrical body in this embodiment has an upper transport device 1620 that is driven by a motor 1621 as in the first embodiment and transports the solid reinforcement material B upward on a mounting piece 1612, and unlike the first embodiment, a filling section 1630 is configured as a feeding device that feeds the material from above. Seventeenth Embodiment Next, a seventeenth embodiment of the present invention will be described with reference to Figure 30. The solid reinforcement material transport device 1710 for a cylindrical body of this embodiment has an upward transport device 1720 consisting of a crane, and is configured to transport the solid reinforcement material B placed in a transport box 1721 upward by the crane and pour it into a filling section 1730 provided in the opening 2. [Embodiment 18] Next, an eighteenth embodiment of the present invention will be described with reference to Figure 31. A solid reinforcement material transport device 1810 for a cylindrical body in this embodiment has an upper transport device 1820 in which a transport basket 1821 is attached to a balloon 1820, and is configured so that the balloon 1820 transports solid reinforcement material B from below to above and fills it through a filling section 1830 connected to the opening 2. A support column 1822 is provided so that the balloon can move straight up and down. [Embodiment 19] Next, a nineteenth embodiment of the present invention will be described with reference to Fig. 32. A solid reinforcement transport device 1910 for a cylindrical body in this embodiment has an upper transport device 1920 consisting of a forklift that moves a transport box 1922 up and down on a transport section 1921, and is configured so that the forklift 1920 transports the solid reinforcement B from below upward and fills it through a filling section 1930 that connects to the opening 2. Twenty Embodiments of the Invention Next, a twentieth embodiment of the present invention will be described with reference to Figures 33 to 41. The solid reinforcement material transport device 2010 for a cylindrical body of this embodiment is configured to include an upward transport device 2020 as upward transport means for transporting a plurality of solid reinforcement materials B from below upward, a lateral transport means for transporting the plurality of solid reinforcement materials B transported upward by the upward transport device 2020 further upward and then transporting them in a substantially lateral direction, and a filling unit 2040 which also serves as a filling means for filling the inside 3 of the cylindrical body from the opening 2.

[0069] Furthermore, the solid reinforcement material transport device 2010 for cylindrical bodies in this embodiment is configured to be separable, so that it can be divided according to the distance to transport multiple solid reinforcement materials B and adjusted to the appropriate length for use. Here, the upper transport device 2020 is configured to be separable into multiple divided bodies 2050 (shown in Figures 37 and 38), 2060, 2070, and 2080, which can be appropriately combined to transport the solid reinforcement materials B upward to a predetermined height. Here, the divided bodies 2050, 2060, 2070, and 2080 are configured to be connected in a substantially straight line (vertical row) from bottom to top. Note that the upper transport device does not necessarily have to be separable into divided bodies, and it may also be configured as a single device without being configured to be separable into divided bodies.

[0070] In this embodiment, the filling section 2040 is configured to be separable into an upper conveying section 2041 and a lateral conveying section 2042 that also serves as lateral conveying means and filling means. Here, a solid reinforcement material spill prevention shutter device 2091 is provided at the boundary between the upper conveying section 2041 and the lateral conveying section 2042. This solid reinforcement material spill prevention shutter device 2091 is designed to automatically lower a shutter on the upper conveying section 2041 by the force of a biasing means such as a spring when the upper conveying section 2041 and the lateral conveying section 2042 are removed, for example, during dismantling of the solid reinforcement material conveying device 2010 for cylindrical bodies. This prevents the solid reinforcement material B from spilling even if it remains in the upper conveying section 2041, enabling safe dismantling.

[0071] The configuration of the filling section 2040 is not limited to this, and depending on the situation, it may be further separable so that the length in the vertical and horizontal directions can be adjusted, or the length of the filling part may be changed. Also, the filling section 2040 may not be separable and may be formed as a single member.

[0072] 33 to 39, the upper conveying device 2020 is configured by connecting a plurality of divided bodies 2050, 2060, 2070, and 2080 as described above, and each divided body 2050, 2060, 2070, and 2080 has a hollow portion 2051, 2061, 2071, and 2081 for transporting the solid reinforcement material B along the top and bottom, respectively, and these hollow portions 2051, 2061, 2071, and 2081 are connected linearly so as to be connected in a straight line. In addition, a push-up drive device 2021 is provided below the lowest divided body 2050 as a push-up means.

[0073] The push-up drive device 2021 alone is used to push up from below the solid reinforcement materials B that are lined up in a vertical row in contact with the hollow portions 2051, 2061, 2071, and 2081. Here, each time the push-up drive device 2021 moves up and down, it pushes up approximately one solid reinforcement material B at a time. Note that the portions of the hollow portions 2051, 2061, 2071, and 2081 that come into contact with the solid reinforcement materials B are made of a slippery material and have a shape that allows the solid reinforcement materials B to move smoothly when pushed up, and furthermore, the inner width (inner diameter) of the hollow portions 2051, 2061, 2071, and 2081 is formed to be large enough to allow just one solid reinforcement material B to pass through.

[0074] Furthermore, the upper end of the push-up drive device 2021 and the lower end of each divided body 2050, 2060, 2070, 2080 are provided with return stoppers 2022, 2052, 2062 (the return stoppers of the divided bodies 2070, 2080 are not shown), respectively. These return stoppers 2022, 2052, 2062 are configured to prevent the solid reinforcing material B, once it has reached above the stoppers, from returning below the stoppers. Specifically, as shown in FIGS. 36 and 39, the return stoppers 2022, 2052, 2062 are provided in a substantially L-shape and are composed of two members of the same shape attached symmetrically. Furthermore, they are rotatable about predetermined shafts 2023, 2053, 2063. When the solid reinforcement B attempts to pass from below to above, the upper ends of these two components rotate in an opening direction, allowing the solid reinforcement B to pass through. Conversely, when the solid reinforcement B attempts to pass from above to below, the upper ends rotate in a closing direction, preventing the solid reinforcement B from passing through.

[0075] With this configuration, when the push-up drive device 2021 pushes up one solid reinforcing material B, the solid reinforcing material B at the positions of the return stoppers 2022, 2052, 2062 cannot return downward after passing from below to above, and is reliably pushed up one solid. By repeating this process, the solid reinforcing material B is reliably pushed up and finally filled into the interior 3 of the cylindrical body.

[0076] In addition, the push-up drive device 2021 is not limited to being installed only below the lowest divided body 2050, but push-up drive devices may also be installed at one or more locations along the upper conveying device 2020, and these may work together to transport the solid reinforcement material B upward.

[0077] Also, as shown in Figure 35, the push-up drive device 2021 provided at the bottom of the upward conveying device 2020 is provided with an inflow passage 2025 for the solid reinforcement material B, and this inflow passage is inclined so that the solid reinforcement material B is taken into the upward conveying device 2020 and conveyed upward by the push-up drive device 2021.

[0078] Furthermore, the solid reinforcing material B transported to a position above the topmost divided body 2080 passes through the inside of the upper conveying section 2041 of the filling section 2040 provided above it, is pushed out horizontally (diagonally downward) from the top, passes through the bellows-shaped, cylindrical horizontal conveying section 2042, and is poured into the interior 3 of the cylindrical body 1 through the opening 2 of the cylindrical body, as shown in Figures 40 and 41.

[0079] As in the above-described embodiment 1, a contact sensor protruding downward from the filling section 2040 is arranged along the edge of the opening 2 of the cylindrical body 1, and support sections 2011 and 2012 are attached laterally to the upper and lower ends of the cylindrical body 1, so that the cylindrical body 1 is configured to support the push-up drive device 2021 and the filling section 2040.

[0080] This embodiment also includes a control unit (not shown) that controls and drives the push-up drive device 2021. This embodiment also includes a solid reinforcement material filling stopper means that can stop the filling of the solid reinforcement material B from entering the cylindrical body interior 3 when the solid reinforcement material B filled through the opening 2 nearly fills the cylindrical body interior 3. This solid reinforcement material filling stopper means includes a sensor as a detection means and a control unit as a stop means. Here, the sensor includes a contact sensor that protrudes downward from the filling section 2040 and is arranged along the edge of the opening 2 of the cylindrical body 1. When the solid reinforcement material B comes into contact with this sensor, a contact signal is sent to the control unit, and in response, the control unit automatically sends a stop signal to the push-up drive device 2021. When the stop signal is sent, the push-up drive device 2021 is stopped, thereby halting the upward supply of the solid reinforcement material B.

[0081] In this embodiment, a forced stopper device 2090 is provided as second stopping means. Similar to the first embodiment, this stopper device 2090 is disposed near the filling section 2040 and has a stopper that is generally L-shaped in cross section. This stopper forcibly stops the filling of the solid reinforcing material B from the filling section 2040 into the cylindrical body interior 3, and is normally biased by a biasing means such as a spring to hold it in an open position.

[0082] When the solid reinforcing material B approaches a full state inside the cylindrical body 3 and a signal indicating that the sensor detects this is being detected, a stop signal is automatically sent by the control unit to issue a forced stop signal, the open / close member is released, and the biasing means rotates to close the flow path of the filling section 2040. This prevents the solid reinforcing material B from being forcibly flowed in through the opening 2, and prevents any more solid reinforcing material B from being filled into the cylindrical body 3.

[0083] In this embodiment, similarly to the first embodiment described above, after the solid reinforcing material B is filled into the cylindrical body interior 3, a pressurizing step is carried out in which the solid reinforcing material B filled into the cylindrical body interior 3 is pressed from the opening 2 side using a pressurizing jig to form a state in which the solid reinforcing material B is less likely to move within the cylindrical body interior 3, both among itself and between the solid reinforcing material B and the cylindrical body interior 3. This further increases the strength of the cylindrical body 1.

[0084] Next, a method for transporting a solid reinforcement material for a cylindrical body using the device 2010 for transporting a solid reinforcement material for a cylindrical body according to this embodiment will be described.

[0085] First, in a preparation step, the support parts 2011 and 2012 are attached to the cylindrical body 1. Then, the filling part 2040, the divided bodies 2050, 2060, 2070, and 2080, and the push-up drive device 2021 are assembled to fit the cylindrical body 1 to a predetermined height (a length slightly higher than the cylindrical body 1).

[0086] 40 and 41, a wire (not shown) is passed through an opening 2013 formed in the support portion 2012, and further connected to the upper conveying portion 2041 of the filling portion 2040 and the divided body 2080. This is then passed through an opening formed in the divided body 2080 (an opening formed in each divided body, such as the opening 2055 shown in FIG. 35) and lifted up. Along the way, the lower divided body 2070 is attached to the divided body 2080, and then the divided bodies 2060 and 2050 are also attached, and finally the push-up drive device 2021 is attached. This allows the upper conveying portion 2041, divided bodies 2050, 2060, 2070, 2080, and push-up drive device 2021 of the filling portion 2040 to be smoothly lifted upward while being connected.

[0087] Then, when it reaches a predetermined height, one end of the horizontal conveying section 2042 is attached to the upper conveying section 2041 of the filling section 2040, and the other end is attached to the opening 2 of the cylindrical body 1. Also, an inflow passage 2025 is attached to the lowest push-up driving device 2021. This completes the preparation of the solid reinforcement material conveying device 2010.

[0088] Once preparations are complete, the conveying process is carried out. Here, the solid reinforcing material B is taken in from the lowest push-up drive device 2021, and in the upward conveying process by the upward conveying device 2020, it is conveyed from the top divided body 2080 to the upper conveying section 2041 of the filling section 2040, and in the filling process, the solid reinforcing material B is poured from the filling section 2040 into the opening 2 of the cylindrical body 1, and the inside 3 of the cylindrical body is filled with the solid reinforcing material B.

[0089] As in the first embodiment described above, the present embodiment is provided with a solid reinforcement material filling stopper process including a detection process using a sensor that detects that the interior 3 of the cylindrical body is nearly full with the solid reinforcement material B filled through the opening 2, and a stop process in which a control unit stops the motor to stop the filling of the solid reinforcement material B into the interior 3 of the cylindrical body when the detection process detects that the interior 3 is nearly full, thereby safely and reliably filling the interior 3 of the cylindrical body with the solid reinforcement material B. In the solid reinforcement material filling stopper process, instead of or in addition to stopping the motor, a stopper device 90 is used to forcibly stop the inflow of the solid reinforcement material B.

[0090] Thereafter, in this embodiment, the same pressurizing step as in the first embodiment is carried out.

[0091] As described above, according to the solid reinforcement material conveying devices 10 to 2010 for cylindrical bodies of embodiments 1 to 20, by having a conveying means and a conveying process for conveying multiple solid reinforcement materials B to the opening 2 of the cylindrical body 1 and filling the interior 3 of the cylindrical body from the opening 2, the solid reinforcement materials B can be filled into the interior 3 of the cylindrical body simply and efficiently.

[0092] Furthermore, according to embodiments 1 and 20, a solid reinforcing material filling stopper means and a solid reinforcing material filling stopper process are provided that stop the filling of the solid reinforcing material B when it is detected that the interior of the cylindrical body 3 is nearly full, thereby preventing the solid reinforcing material B from overflowing from the opening 2 and causing damage to the surrounding area.

[0093] Furthermore, according to embodiments 1 and 20, when the cylindrical body 1 is erected in an approximately vertical direction with the opening 2 at the top, by transporting multiple solid reinforcing materials B from below to above and filling them into the interior 3 of the cylindrical body, the solid reinforcing materials B can be reliably filled into the cylindrical body 1 in an erect state.

[0094] Furthermore, according to embodiments 1 and 20, the conveying means and conveying process are divided into upward conveying for conveying upward, lateral conveying for conveying laterally thereafter, and then a means and process for filling the solid reinforcing material B into the interior 3 of the cylindrical body through the opening 2, thereby making it possible to more reliably fill the interior 3 of the cylindrical body with the solid reinforcing material B.

[0095] Furthermore, according to the first and twentieth embodiments, the solid reinforcing material B is formed into a substantially spherical body, so that the solid filler B having a high reinforcing effect can be transported and filled.

[0096] Furthermore, according to embodiments 1 and 20, the conveying means is divisible and can be used by adjusting the length according to the conveying distance of the solid reinforcing material B, so that the solid reinforcing material B can be conveyed at just the right length, without excess or deficiency.

[0097] Furthermore, according to embodiments 1 and 20, by applying pressure to the solid reinforcing material B filled inside the cylindrical body 3, the solid reinforcing materials B can be brought into close contact with each other and made less likely to move, thereby more firmly reinforcing the cylindrical body 1.

[0098] Furthermore, according to embodiment 20, the conveying means and conveying process are configured to arrange multiple solid reinforcing materials B in a vertical row while they are in contact with each other, and the push-up means and push-up process are configured to push up the multiple solid reinforcing materials B in this state from below, so that the solid reinforcing materials B can be reliably transported with a relatively simple structure and the solid reinforcing materials B can be filled into the interior 3 of the cylindrical body.

[0099] It goes without saying that the above-described embodiments are merely examples of the present invention, and that the present invention is not limited to the above-described embodiments. If the object of the present invention can be achieved using other configurations, they may be applied as appropriate.
