Description

Technical Field

[0001] This disclosure relates to a cylinder manufacturing support device and a method for manufacturing a cylinder.

[0002] This application claims priority based on Japanese Patent Application No. 2024-179849, filed on October 15, 2024, the contents of which are incorporated herein by reference. Background Technology

[0003] Patent Document 1 below describes a method for manufacturing a cylindrical tube using multiple metal plates around a cylindrical axis. The tube is manufactured by arranging multiple metal plates circumferentially around the cylindrical axis in a direction extending along the cylindrical axis and in a circumferential direction relative to the cylindrical axis, and joining the multiple metal plates together. In this method, a tube manufacturing support device is used to manufacture the tube.

[0004] The cylinder manufacturing support device includes a portal frame and a crane. The portal frame has: a first column and a second column, which extend vertically and are arranged laterally at intervals on the work floor; and a top beam, which extends laterally and connects the upper ends of the first column and the upper ends of the second column. The crane is mounted on the top beam by means of a clamp in a manner that allows it to move along the top beam.

[0005] Multiple metal plates each have an edge that extends circumferentially and along the cylinder axis. During the manufacturing process of the cylinder, even if the edges of two metal plates that are adjacent in the circumferential direction are brought together, there are cases where a portion of the edge of one metal plate is radially offset relative to a portion of the edge of the other metal plate relative to a portion of the edge of the first metal plate, and a portion of the edge of the other metal plate is not circumferentially offset relative to a portion of the edge of the first metal plate.

[0006] In this case, in the manufacturing method described in Patent Document 1, a lifting device for the support device is manufactured using a cylinder. For example, a portion of one metal plate along its edge is pressed radially inward relative to the cylinder axis, so that a portion of the edge of one metal plate is circumferentially opposed to a portion of the edge of another metal plate. While maintaining this state, a portion of the edge of one metal plate is joined to a portion of the edge of the other metal plate. Furthermore, after moving the two metal plates relative to the portal frame in a depth direction perpendicular to both the vertical and horizontal directions, a lifting device for the support device is manufactured using a cylinder. For example, another portion of one metal plate along its edge is pressed radially inward relative to the cylinder axis, so that another portion of the edge of one metal plate is circumferentially opposed to another portion of the edge of the other metal plate. While maintaining this state, another portion of the edge of one metal plate is joined to another portion of the edge of the other metal plate. This process is repeated until the entire edge of one metal plate extending in the cylinder axis direction is joined to the edge of the other metal plate.

[0009] Patent Document 1: Japanese Patent Application Publication No. 2012-135802 Summary of the Invention

[0010] The problem that the invention aims to solve

[0011] In the technology described in Patent Document 1, when pressing down a portion of the edge of one metal plate using a lifting device, both metal plates need to be supported beforehand to prevent them from moving or tilting due to the pressure from the lifting device. Furthermore, during the process of joining the edges of the two metal plates together, the two metal plates need to move integrally with respect to the portal frame in the depth direction. Therefore, the technology described in Patent Document 1 imposes a burden on the operator.

[0012] Therefore, the purpose of this disclosure is to provide a cylinder manufacturing support device and a cylinder manufacturing method that can reduce the burden on the operator during cylinder manufacturing.

[0013] Methods for solving problems

[0014] A cylinder manufacturing support device, as one solution for achieving the aforementioned objective, is used when a plurality of metal plates extending in the direction of the cylinder axis and in the circumferential direction relative to the cylinder axis are arranged around the cylinder axis in the circumferential direction, and the metal plates that are adjacent in the circumferential direction among the plurality of metal plates are joined together to manufacture a cylinder.

[0015] The cylinder manufacturing support device comprises: a portal frame having a first column and a second column extending vertically and spaced apart from each other laterally, and an upper beam extending laterally and connecting the upper ends of the first column and the second column; a slider capable of supporting the plurality of metal plates between the first column and the second column, and movable in a depth direction perpendicular to both the lateral and vertical directions; an upper pressing mechanism mounted on the upper beam in a manner movable along the upper beam in the lateral direction, capable of pressing any one of the plurality of metal plates supported by the slider; a first lateral pressing mechanism mounted on the first column, capable of pressing any one of the plurality of metal plates supported by the slider; and a second lateral pressing mechanism mounted on the second column, capable of pressing any one of the plurality of metal plates supported by the slider.

[0016] When manufacturing a cylinder using the cylinder manufacturing support device of this solution, a first metal plate and a second metal plate from a plurality of metal plates are brought into contact with the first metal plate in the circumferential direction (joining plate arrangement process). Next, a temporary assembly plate assembly including the first and second metal plates is moved along the depth direction on a slider to adjust the position of the temporary assembly plate assembly by positioning it below the upper beam, such that the predetermined joining position of the second metal plate relative to the edge of the first metal plate in the cylinder axial direction is located at a working position. In this solution, during the position adjustment process, by sliding the temporary assembly plate assembly along the depth direction on the slider, the operator's workload in the position adjustment process can be reduced.

[0017] Next, the first and second lateral pressing mechanisms are operated to clamp the temporary assembly plate group located in the working position, restricting its movement (movement restriction process). By executing this movement restriction process, the temporary assembly plate group is constrained to prevent movement in the lateral and depth directions, and the tilting of the cylinder axis and the tilting around the cylinder axis are restricted.

[0018] Next, during the movement restriction process, a portion of the edge of the first metal plate extending along the cylinder axis and a portion of the edge of the second metal plate extending along the cylinder axis are pressed by the upper pressing mechanism, causing the edge portion of the first metal plate to be circumferentially aligned with the edge portion of the second metal plate (edge ​​alignment process). This edge alignment process is performed during the movement restriction process, thus allowing it to be performed while the movement and tilting of the temporary assembly of the plates are restricted. Then, the edge portion of the first metal plate and the edge portion of the second metal plate are joined together during both the movement restriction process and the edge alignment process (joining process). This joining process is performed during the movement restriction process, thus allowing it to be performed while the movement and tilting of the temporary assembly of the plates are restricted. Therefore, in this solution, the workload of the operator in the edge alignment process and the joining process can be reduced.

[0019] In a method for manufacturing a cylinder as one embodiment of the stated purpose, a cylinder manufacturing support device is used as one embodiment.

[0020] The manufacturing method includes: a preparation step, preparing the plurality of metal plates, a first auxiliary metal plate corresponding to the internal dimensions and internal shape of the first side of the cylinder's axis (one of the first and second sides of the cylinder's axis), and a second auxiliary metal plate corresponding to the internal dimensions and internal shape of the second side of the cylinder's axis (one of the first and second sides of the cylinder's axis); and a temporary joining step, temporarily joining the first metal plate and the third metal plate to the first auxiliary metal plate in a manner that makes the relative positional relationship between the first metal plate and the third metal plate, which are opposed to each other across the cylinder's axis, consistent with the relative positional relationship between the first metal plate and the third metal plate after the cylinder is completed. A portion of the edge of the auxiliary metal plate and a portion of the edge of the second auxiliary metal plate; a placement process, in which the first metal plate and the third metal plate, temporarily joined to the first auxiliary metal plate and the second auxiliary metal plate, are placed on the slider such that the cylinder axis extends along the depth direction; a joining plate arrangement process, in which the edge of the second metal plate (other than the first metal plate and the third metal plate) extending in the circumferential direction and in the direction of the cylinder axis is adjacent to the edge of the metal plate temporarily joined to one of the first metal plate and the third metal plate, extending in the circumferential direction and in the direction of the cylinder axis; A position adjustment step is performed to adjust the position of the temporary assembly plate group, which is a collection of the first auxiliary metal plate, the second auxiliary metal plate, the first metal plate, the second metal plate, and the third metal plate, so that the predetermined engagement position of the second metal plate relative to the edge of one of the metal plates in the direction of the cylinder axis is located on the lower side of the upper beam. A movement restriction step is performed by operating the first lateral pressing mechanism and the second lateral pressing mechanism to clamp the temporary assembly plate group located in the working position and restrict its movement. The movement of the temporary assembly plate group; the edge-aligning process, in the execution of the movement restriction process, using the upper pressing mechanism, pressing a portion of one of the edges of the first metal plate extending along the direction of the cylinder axis and a portion of the edge of the second metal plate extending along the direction of the cylinder axis, so that the portion of the edge of the first metal plate is aligned with the portion of the edge of the second metal plate in the circumferential direction; the joining process, in the execution of the movement restriction process and the edge-aligning process, joining the portion of the edge of the first metal plate with the portion of the edge of the second metal plate;The process includes an auxiliary plate removal step, in which the first auxiliary metal plate and the second auxiliary metal plate are removed from the first metal plate and the third metal plate after the plurality of metal plates are connected to each other. The position adjustment step, the movement restriction step, the edge alignment process, and the joining step are repeated until the entire edge of the second metal plate extending in the direction of the cylinder axis is joined to the edge of one of the metal plates.

[0021] In the cylinder manufacturing method of this solution, since a cylinder manufacturing support device is used as described in the solution, the burden on the operator can be reduced during cylinder manufacturing.

[0106] Hereinafter, an embodiment of the cylinder manufacturing support device of the present invention and a method for manufacturing a cylinder using the cylinder manufacturing support device will be described with reference to the accompanying drawings.

[0107] "Implementation Method of the Cylinder"

[0108] First, the implementation method of the cylinder that is to be manufactured will be described.

[0109] In this embodiment, the cylinder is a cylinder that forms part of the burner of a gas turbine. The burner has a burner nozzle for injecting fuel and air and a combustion cylinder (or tail cylinder) that divides the combustion space for the fuel injected from the burner nozzle to burn. In this embodiment, the cylinder is the combustion cylinder.

[0110] like Figure 1As shown, in this embodiment, the cylinder 1 is cylindrical around the cylinder axis At. Here, the direction in which the cylinder axis At extends is defined as the cylinder axis direction Da, one of the two sides on the cylinder axis direction Da is defined as the first axis side Da1, and the other side on the cylinder axis direction Da is defined as the second axis side Da2. In addition, the circumferential direction relative to the cylinder axis At is defined as the circumferential direction Dc, one of the two sides on the circumferential direction Dc is defined as the first circumferential direction side Dc1, and the other side on the circumferential direction Dc is defined as the second circumferential direction side Dc2.

[0111] In this embodiment, the cylinder axis At of cylinder 1 is not a straight line, but rather... Figure 3 As shown, it is curved. Figure 1 As shown, a first opening is formed at the end of the cylinder 1 on the first side Da1 of the axis, opening from the inside toward the first side Da1. A second opening is formed at the end of the cylinder 1 on the second side Da2 of the axis, opening from the inside toward the second side Da2. The cross-section of the cylinder 1 on the imaginary plane perpendicular to the cylinder axis At has different cross-sectional shapes and dimensions depending on the position of the cylinder axis direction Da. For example, the cross-sectional shape at the end of the cylinder 1 on the first side Da1 of the axis is circular. In addition, the cross-sectional shape at the end of the cylinder 1 on the second side Da2 of the axis is an isosceles trapezoid, and the cross-sectional dimension is smaller than that at the end of the cylinder 1 on the first side Da1 of the axis.

[0112] In this embodiment, the cylinder 1 is manufactured by joining multiple metal plates 3 together. The number of metal plates 3 in this embodiment is four. Each of the multiple metal plates 3 extends along the cylinder's axial direction Da and circumferential direction Dc. However, the multiple metal plates 3 are not flat but curved. Each of the multiple metal plates 3 has an inner circumferential surface 4 forming a portion of the inner circumferential surface of the cylinder 1, an outer circumferential surface 5 forming a portion of the outer circumferential surface of the cylinder 1, and an edge 6. The edge 6 has a first edge 6a extending toward the first circumferential side Dc1 and along the cylinder's axial direction Da, and a second edge 6b extending toward the second circumferential side Dc2 and along the cylinder's axial direction Da. The multiple metal plates 3 are arranged circumferentially around the cylinder axis At along the cylinder's circumferential direction Dc, and the edges 6 of circumferentially adjacent metal plates 3 in the multiple metal plates 3 are joined together.

[0113] It should be noted that, as described above, the cylinder 1 in this embodiment is a combustion cylinder (or tail cylinder). However, the cylinder 1 can be any cylinder as long as it is formed by arranging multiple metal plates 3 around the cylinder axis At in the circumferential direction Dc and joining the multiple metal plates 3 together.

[0114] Implementation method of "Cylinder manufacturing support device"

[0115] Reference Figures 2-8 The implementation method of the cylinder manufacturing support device will be described.

[0116] like Figures 2-4 As shown, the cylinder manufacturing support device M in this embodiment includes a gate-shaped frame 10, an upper pressing mechanism 20, a first transverse pressing mechanism 20a, a second transverse pressing mechanism 20b, an upper base support frame 30, a first base support frame 40a, a second base support frame 40b, a first base swing mechanism 45a, a second base swing mechanism 45b, a first support frame moving mechanism 50a, a second support frame moving mechanism 50b, a slider 60, and a plurality of legs 65.

[0117] The portal frame 10 has a first column 11a and a second column 11b extending in the vertical direction Dv and spaced apart from each other in the transverse direction Ds, and an upper beam 12 extending in the transverse direction Ds and connecting the upper ends of the first column 11a and the second column 11b. A guide hole 13 is formed in the upper beam 12, penetrating in the vertical direction Dv and extending in the transverse direction Ds. The portion of the upper beam 12 including the area where the guide hole 13 is formed curves such that it gradually moves towards the vertically upward side as the first column 11a approaches the center of the upper beam 12 in the transverse direction Ds, and gradually moves towards the vertically upward side as the second column 11b approaches the center.

[0118] like Figure 5 As shown, the upper pressing mechanism 20, the first lateral pressing mechanism 20a, and the second lateral pressing mechanism 20b each have a base 21 and a front end 22 that can move relative to the base 21 in the front end moving direction. Specifically, the upper pressing mechanism 20, the first lateral pressing mechanism 20a, and the second lateral pressing mechanism 20b are all hydraulic cylinders that use hydraulic pressure to move the front end 22. The hydraulic cylinder has a piston rod and a working cylinder housing. The piston rod extends in the front end moving direction and has a front end 22 as the end in the front end moving direction. The working cylinder housing constitutes the base 21 of each pressing mechanism 20, 20a, and 20b, covering the piston rod in a state where the piston rod can move in the front end moving direction and the front end 22 is exposed. A contact end 23 that can contact any of the metal plates 3 constituting the cylinder 1 is installed at the front end 22 of the first lateral pressing mechanism 20a and the front end 22 of the second lateral pressing mechanism 20b.

[0119] The base 21 of the upper pressing mechanism 20 is mounted on the upper beam 12 via the upper base support frame 30 in such a way that the front end moving direction has a vertical component Dv and the front end 22 of the upper pressing mechanism 20 faces downward.

[0120] like Figure 5 as well as Figure 8As shown, the upper base support frame 30 is a groove-shaped member having a pair of side plates 31 spaced apart from each other and a base plate 33 connecting the ends of the pair of side plates 31 to each other. Base insertion holes 32 are formed in each of the pair of side plates 31, extending through the direction in which the pair of side plates 31 are arranged. The upper base support frame 30 is configured such that the upper beam 12 is located between the pair of side plates 31 and is movable relative to the upper beam 12 in the lateral direction Ds. The base 21 of the upper pressing mechanism 20 is fixed to the upper base support frame 30 in a state where it is inserted into the base insertion holes 32 formed in the pair of side plates 31 and the guide holes 13 formed in the upper beam 12. Therefore, the upper base support frame 30 and the base 21 of the upper pressing mechanism 20 supported on the upper base support frame 30 are movable relative to the upper beam 12 in the lateral direction Ds within the range where the guide holes 13 are formed in the upper beam 12. The upper base support frame 30 is provided with a lateral movement limiting bolt 34 for limiting the lateral movement Ds relative to the upper beam 12.

[0121] The base 21 of the first lateral pressing mechanism 20a is mounted on the first column 11a via the first base support frame 40a, with the front end moving in a lateral direction having a component of Ds and the front end 22 of the first lateral pressing mechanism 20a facing the second column 11b. The base 21 of the first lateral pressing mechanism 20a is mounted on the first base support frame 40a in a manner that allows it to swing via the first base swing mechanism 45a. The first base support frame 40a is mounted on the first column 11a in a manner that allows it to move in the vertical direction Dv via the first support frame moving mechanism 50a.

[0122] The base 21 of the second lateral pressing mechanism 20b is mounted on the second column 11b via the second base support frame 40b, with the front end moving in a lateral component Ds and the front end 22 of the second lateral pressing mechanism 20b facing the first column 11a. The base 21 of the second lateral pressing mechanism 20b is mounted on the second base support frame 40b in a manner that allows it to swing via the second base swing mechanism 45b. The second base support frame 40b is mounted on the second column 11b in a manner that allows it to move in the vertical direction Dv via the second support frame moving mechanism 50b.

[0123] The second base support frame 40b has the same structure as the first base support frame 40a, except that the orientation of the lateral Ds is opposite to that of the first base support frame 40a. The second base swing mechanism 45b has the same structure as the first base swing mechanism 45a, except that the orientation of the lateral Ds is opposite to that of the first base swing mechanism 45a. The second support frame moving mechanism 50b has the same structure as the first support frame moving mechanism 50a, except that the orientation of the lateral Ds is opposite to that of the first support frame moving mechanism 50a. Therefore, the following description only covers the structures of the first base support frame 40a, the first base swing mechanism 45a, and the first support frame moving mechanism 50a, omitting the description of the structures of the second base support frame 40b, the second base swing mechanism 45b, and the second support frame moving mechanism 50b.

[0124] like Figure 5 As shown, the first base support frame 40a has a pair of support plates 41 arranged to clamp the first column 11a in the depth direction Dl perpendicular to the vertical direction Dv and the lateral direction Ds (see reference). Figure 3 and Figure 5 The base retaining ring 42 holds the portion of the base 21 of the first lateral pressing mechanism 20a at the front end 22 side. The base retaining ring 42 has a swing shaft 43 extending along the depth direction Dl. The base retaining ring 42 is mounted on a pair of support plates 41 in such a way that it can rotate together with the base 21 of the first lateral pressing mechanism 20a held by the base retaining ring 42 about the swing shaft 43.

[0125] like Figure 5 as well as Figure 7 As shown, the first base swing mechanism 45a has a swing operating end 46, a swing screw 47, and a swing linkage mechanism 48. The swing operating end 46 is mounted on a pair of support plates 41 in a manner that allows it to rotate about the axis 49 of the swing screw, which extends in the vertical direction Dv. An internal threaded hole is formed in the swing operating end 46, extending in the vertical direction Dv with the axis 49 of the swing screw as the center. The swing screw 47 is screwed into the internal threaded hole of the swing operating end 46. Therefore, when the swing operating end 46 is rotated about the axis 49 of the swing screw, the swing screw 47 moves relative to the swing operating end 46 in the vertical direction Dv. A part of the swing linkage mechanism 48 is connected to the front end of the swing screw 47. In addition, another part of the swing linkage mechanism 48 is connected to the base end side of the base 21 of the first transverse pressing mechanism 20a. Therefore, by operating the swing operating end 46, the base 21 of the first transverse pressing mechanism 20a swings about the swing axis 43.

[0126] like Figure 5 and Figure 6As shown, the first support frame moving mechanism 50a includes a moving operating end 51, an internal thread member 52, and a connecting member 53. The moving operating end 51 is mounted on the upper beam 12 in a manner rotatable about a moving thread axis 54 extending in the vertical direction Dv. The upper vertical end of the moving operating end 51 is located at a position higher than the upper beam 12 and forms an operating section. The lower vertical end of the moving operating end 51 is located at a position lower than the upper beam 12 and has an external thread. The internal thread member 52 has an internal threaded hole extending in the vertical direction Dv with the moving thread axis 54 as its center. The external thread of the moving operating end 51 is screwed into this internal threaded hole. Therefore, when the moving operating end 51 is rotated about the moving thread axis 54, the internal thread member 52 moves relative to the moving operating end 51 in the vertical direction Dv. The connecting member 53 connects the internal thread member 52 to a pair of support plates 41. Therefore, by operating the moving end 51, the first base support frame 40a having a pair of support plates 41, the base 21 supported on the first base support frame 40a, and the first base swing mechanism 45a provided on the first base support frame 40a move integrally along the first column 11a in the vertical direction Dv.

[0127] like Figure 2 and Figure 4 As shown, the slider 60 supports the component between the first post 11a and the second post 11b, enabling it to move along the depth direction Dl. Here, "enabling the component to move in the depth direction Dl" means that the article can be moved with less effort compared to moving it in the vertical direction Dv and the transverse direction Ds. The slider 60 is a roller conveyor having a pair of roller guides 61 and a plurality of rollers 62. The pair of roller guides 61 extend along the depth direction Dl and are spaced apart from each other in the transverse direction Ds between the first post 11a and the second post 11b. The plurality of rollers 62 are arranged along the depth direction Dl and positioned between the pair of roller guides 61, supported on the pair of roller guides 61 in a manner that allows them to rotate about the axis of the rollers 62 extending in the transverse direction Ds.

[0128] Multiple legs 65 support the portal frame 10 and the slider 60.

[0129] "Implementation Method of the Manufacturing Method of the Cylinder"

[0130] according to Figure 9 The flowchart shown illustrates an embodiment of the manufacturing method of cylinder 1 using the cylinder manufacturing support device M described above.

[0131] First, such as Figure 10As shown, four metal plates 3, a first auxiliary metal plate 71a, and a second auxiliary metal plate 71b are prepared to form cylinder 1 (preparation step S1). The first auxiliary metal plate 71a is a circular metal plate that corresponds to the internal dimensions and internal shape of the first side Da1 of the axis of cylinder 1. In addition, the second auxiliary metal plate 71b is a trapezoidal metal plate that corresponds to the internal dimensions and internal shape of the second side Da2 of the axis of cylinder 1.

[0132] Next, the first metal plate 3a and the third metal plate 3c, which are opposite each other across the cylinder axis At, are temporarily joined to a portion of the edge of the first auxiliary metal plate 71a and a portion of the edge of the second auxiliary metal plate 71b (temporary joining step S2). By performing this temporary joining step S2, the relative positional relationship between the first metal plate 3a and the third metal plate 3c is substantially the same as the relative positional relationship between the first metal plate 3a and the third metal plate 3c in the cylinder 1 at the end.

[0133] Next, as Figure 2 As shown, with the cylinder axis At extending along the depth direction Dl and the first metal plate 3a located on the side closer to the first post 11a than the third metal plate 3c, the first metal plate 3a and the third metal plate 3c, temporarily joined to the first auxiliary metal plate 71a and the second auxiliary metal plate 71b, are placed on the slider 60 (loading process S3). It should be noted that in... Figure 2 In the process, a working plate 69 is placed on the slider 60, and a first metal plate 3a and a second metal plate 3b, which are temporarily attached to the first auxiliary metal plate 71a and the second auxiliary metal plate 71b, are placed on the working plate 69 together with the first auxiliary metal plate 71a and the second auxiliary metal plate 71b.

[0134] Next, as Figure 10 As shown, the first edge 6a of the second metal plate 3b extending toward the circumferential first side Dc1 and in the cylindrical axis direction Da is abutted to the second edge 6b of the first metal plate 3a extending toward the circumferential second side Dc2 and in the cylindrical axis direction Da, which is temporarily joined to the first auxiliary metal plate 71a and the second auxiliary metal plate 71b (joining plate arrangement step S4). It should be noted that in this joining plate arrangement step S4, the second edge 6b of the second metal plate 3b may also be abutted to the first edge 6a of the third metal plate 3c temporarily joined to the first auxiliary metal plate 71a and the second auxiliary metal plate 71b. Here, the set of the first auxiliary metal plate 71a, the second auxiliary metal plate 71b, the first metal plate 3a, the third metal plate 3c, and the second metal plate 3b, which serves as a joining plate joined to the first metal plate 3a, is designated as a temporary assembly plate group 9.

[0135] Next, as Figure 11As shown, in the first edge 6a of the second metal plate 3b, the temporary assembly plate group 9 is slid along the depth direction Dl on the slider 60 in a manner that the predetermined engagement position relative to the second edge 6b of the first metal plate 3a in the cylindrical axis direction Da is located below the upper beam 12, thereby adjusting the position of the temporary assembly plate group 9 (position adjustment step S5). It should be noted that the aforementioned engagement plate configuration step S4 can be performed at any time as long as it is before the position adjustment step S5 and after the temporary engagement step S2.

[0136] Next, operate the first lateral pressing mechanism 20a and the second lateral pressing mechanism 20b, as follows: Figure 12 As shown, the movement restriction step S6 is performed. In this movement restriction step S6, firstly, the movement operation end 51 of the first support frame moving mechanism 50a is operated to adjust the vertical direction Dv position of the base 21 of the first transverse pressing mechanism 20a, so that the contact end 23 provided at the front end 22 of the first transverse pressing mechanism 20a is opposite to the first metal plate 3a in the transverse direction Ds. Furthermore, the swing operation end 46 of the first base swing mechanism 45a is operated to adjust the tilt of the base 21 of the first transverse pressing mechanism 20a. Additionally, the movement operation end 51 of the second support frame moving mechanism 50b is operated to adjust the vertical direction Dv position of the base 21 of the second transverse pressing mechanism 20b, so that the contact end 23 provided at the front end 22 of the second transverse pressing mechanism 20b is opposite to the third metal plate 3c in the transverse direction Ds. Finally, the swing operation end 46 of the second base swing mechanism 45b is operated to adjust the tilt of the base 21 of the second transverse pressing mechanism 20b. Next, the front end 22 of the first lateral pressing mechanism 20a is moved relative to the base 21 of the first lateral pressing mechanism 20a, and the front end 22 of the second lateral pressing mechanism 20b is moved relative to the base 21 of the second lateral pressing mechanism 20b, thereby clamping the temporary assembly plate group 9 using the front ends 22 of the first lateral pressing mechanism 20a and the front ends 22 of the second lateral pressing mechanism 20b. At this time, the contact end 23 provided at the front end 22 of the first pressing mechanism contacts the outer peripheral surface 5 of the first metal plate 3a in the temporary assembly plate group 9, and the contact end 23 provided at the front end 22 of the second pressing mechanism contacts the outer peripheral surface 5 of the second metal plate 3b in the temporary assembly plate group 9.

[0137] By performing the movement restriction process S6, the temporary assembly plate group 9 is restricted from moving laterally Ds and in the depth direction Dl, and the tilting of the cylinder axis At and the tilting around the cylinder axis At are restricted.

[0138] Next, as Figures 12-14As shown, during the execution of the movement restriction step S6, the upper pressing mechanism 20 presses a portion of the outer peripheral surface 5 of the second metal plate 3b, located at a predetermined engagement position relative to the second edge 6b of the first metal plate 3a along the cylindrical axis direction Da, in a direction having a vertically downward directional component. At this time, to avoid damaging the outer peripheral surface 5 of the second metal plate 3b, it is preferable to place a pad 72 made of copper or the like, which is softer than the metal plate 3, between the front end 22 of the upper pressing mechanism 20 and the outer peripheral surface 5 of the second metal plate 3b. Then, a portion of the first edge 6a of the second metal plate 3b is aligned with a portion of the second edge 6b of the first metal plate 3a in the circumferential direction Dc, so that the outer peripheral surface 5 of the second metal plate 3b and the outer peripheral surface 5 of the first metal plate 3a are substantially in the same plane (edge ​​alignment processing step S7). This edge alignment processing step S7 is performed during the execution of the movement restriction step S6, thus allowing the edge alignment processing step S7 to be performed while the movement and tilting of the temporary assembly plate group 9 are restricted.

[0139] It should be noted that, as mentioned above, Figure 13 As shown, a portion of the first edge 6a of the second metal plate 3b is located radially outward (Dro) relative to a portion of the second edge 6b of the first metal plate 3a relative to the cylinder axis At. Therefore, the upper pressing mechanism 20 presses a portion of the outer peripheral surface 5 of the second metal plate 3b along the portion of the first edge 6a towards a direction having a vertically downward component. However, when a portion of the second edge 6b of the first metal plate 3a is located radially outward (Dro) relative to the cylinder axis At, in the edge-aligning processing step S7, the upper pressing mechanism 20 presses a portion of the outer peripheral surface 5 of the first metal plate 3a along the portion of the second edge 6b towards a direction having a vertically downward component.

[0140] Next, during the execution of the movement restriction step S6 and the edge alignment process S7, a portion of the first edge 6a of the second metal plate 3b is joined to a portion of the second edge 6b of the first metal plate 3a (joining step S8). This joining step S8 is performed during the execution of the movement restriction step S6, so the joining step S8 can be performed while the movement and tilting of the temporary assembly plate group 9 are restricted.

[0141] Next, the operator determines whether the entire edge 6 of the second metal plate 3b is engaged with the edges 6 of the first metal plate 3a and the third metal plate 3c (first determination step S9). If the entire edge 6 of the second metal plate 3b is not engaged with the edges 6 of the first metal plate 3a and the third metal plate 3c, the steps S5 to S9 described above are repeated until the entire edge 6 of the second metal plate 3b is engaged with the edges 6 of the first metal plate 3a and the third metal plate 3c.

[0142] When it is determined in the first judgment step S9 that the edge 6 of the second metal plate 3b is joined to the edges 6 of the first metal plate 3a and the third metal plate 3c, the operator determines whether all the metal plates 3 are joined to each other (second judgment step S10). When it is determined that all the metal plates 3 are not joined to each other, the above-described steps S4 to S10 are repeated until all the metal plates 3 are joined to each other.

[0143] For example, assuming that in the second judgment step S10 it is determined that the fourth metal plate 3d is not joined with other metal plates 3, then after performing the joining plate arrangement step S4 on the fourth metal plate 3d, the steps S5 to S9 described above are repeatedly performed on the fourth metal plate 3d. Furthermore, if the operator determines in the first judgment step S9 that the entire edge 6 of the fourth metal plate 3d is joined with the edges 6 of the first metal plate 3a and the third metal plate 3c, then the operator performs the second judgment step S10.

[0144] When the operator determines in the second judgment process S10 that all the metal plates 3 are joined together, the first auxiliary metal plate 71a and the second auxiliary metal plate 71b are removed from the temporary assembly plate group 9 (auxiliary plate removal process S11).

[0145] That concludes the process for cylinder 1.

[0146] In this embodiment, during the position adjustment process S5, when the temporary assembly plate group 9 is moved along the depth direction D1, the operator's workload in the position adjustment process S5 can be reduced by allowing the temporary assembly plate group 9 to slide on the slider 60. Furthermore, in this embodiment, the edge alignment process S7 and the joining process S8 can be performed while the movement and tilting of the temporary assembly plate group 9 are restricted, thus reducing the operator's workload in these processes.

[0147] "Variations"

[0148] In the above embodiments, the upper pressing mechanism 20, the first lateral pressing mechanism 20a, and the second lateral pressing mechanism 20b are all hydraulic cylinders. However, these pressing mechanisms 20, 20a, and 20b could also be, for example, electromagnetic cylinders, cranes with linkage mechanisms, etc.

[0149] In the above embodiments, the slider 60 is a roller conveyor having a plurality of rollers 62 arranged along the depth direction Dl. However, the slider can be any structure as long as it can move the article along the depth direction Dl with less labor compared to moving the article in the vertical direction Dv and the horizontal direction Ds. For example, it can also be a belt conveyor having a belt extending along the depth direction Dl.

[0150] In the above embodiment, the number of metal plates 3 constituting the cylinder 1 is four. However, the number of metal plates 3 can be any number, as long as there are three or more.

[0151] Furthermore, this disclosure is not limited to the embodiments described above. Various additions, modifications, substitutions, partial deletions, etc., can be made without departing from the conceptual idea and spirit of the present invention derived from the content specified in the technical solution and its equivalents.

[0152] Postscript

[0153] The cylinder manufacturing support device M in the above embodiments and variations is understood as follows.

[0154] (1) The cylinder manufacturing support device M in the first embodiment is used when a plurality of metal plates 3 extending in the cylinder axis direction Da and in the circumferential direction Dc relative to the cylinder axis At are arranged around the cylinder axis At along the circumferential direction Dc, and adjacent metal plates 3 in the circumferential direction Dc are joined together to manufacture a cylinder 1. The cylinder manufacturing support device M includes: a portal frame 10 having a first column 11a and a second column 11b extending in the vertical direction Dv and spaced apart from each other in the transverse direction Ds, and an upper beam 12 extending in the transverse direction Ds and connecting the upper end of the first column 11a to the upper end of the second column 11b; a slider 60 between the first column 11a and the second column 11b, which can support the plurality of metal plates 3 so that they can move in the depth direction Dl perpendicular to the transverse direction Ds and the vertical direction Dv; and an upper pressing mechanism. 20, which is mounted on the upper beam 12 in a manner that allows it to move along the upper beam 12 in the transverse direction Ds, and is capable of pressing any one of the plurality of metal plates 3 supported by the slider 60; a first transverse pressing mechanism 20a, which is mounted on the first column 11a, and is capable of pressing any one of the plurality of metal plates 3 supported by the slider 60; and a second transverse pressing mechanism 20b, which is mounted on the second column 11b, and is capable of pressing any one of the plurality of metal plates 3 supported by the slider 60.

[0155] When manufacturing cylinder 1 using the cylinder manufacturing support device M of this solution, the first metal plate 3a and the second metal plate 3b of the plurality of metal plates 3 are brought abutted against the first metal plate 3a in the circumferential direction Dc (joining plate arrangement step S4). Next, the temporary assembly plate group 9, including the first metal plate 3a and the second metal plate 3b, is slid along the depth direction Dl on the slider 60 to adjust the position of the temporary assembly plate group 9 in such a way that the predetermined joining position of the edge 6 of the second metal plate 3b in the cylinder axial direction Da relative to the edge 6 of the first metal plate 3a is located below the upper beam 12 (position adjustment step S5). In this solution, in the position adjustment step S5, by sliding the temporary assembly plate group 9 on the slider 60 while moving it along the depth direction Dl, the burden on the operator in the position adjustment step S5 can be reduced.

[0156] Next, the first lateral pressing mechanism 20a and the second lateral pressing mechanism 20b are operated to clamp the temporary assembly plate group 9 located in the working position, thereby restricting the movement of the temporary assembly plate group 9 (movement restriction step S6). By executing this movement restriction step S6, the temporary assembly plate group 9 is constrained to prevent movement in the lateral direction Ds and the depth direction Dl, and the tilting of the cylinder axis At and the tilting around the cylinder axis At are restricted.

[0157] Next, during the execution of the movement restriction step S6, the upper pressing mechanism 20 presses down on a portion of the edge 6 of the first metal plate 3a extending along the cylindrical axis direction Da, and a portion of the edge 6 of the second metal plate 3b extending along the cylindrical axis direction Da, so that a portion of the edge 6 of the first metal plate 3a and a portion of the edge 6 of the second metal plate 3b are aligned in the circumferential direction Dc (edge ​​alignment processing step S7). This edge alignment processing step S7 is performed during the execution of the movement restriction step S6, so it can be performed while the movement and tilting of the temporary assembly plate group 9 are restricted. Then, the portion of the edge 6 of the first metal plate 3a and the portion of the edge 6 of the second metal plate 3b are joined during the execution of both the movement restriction step S6 and the edge alignment processing step S7 (joining step S8). This joining step S8 is performed during the execution of the movement restriction step S6, so it can be performed while the movement and tilting of the temporary assembly plate group 9 are restricted. Therefore, this solution can reduce the burden on operators in the edge alignment process S7 and the joining process S8.

[0158] (2) In the second embodiment, the cylinder manufacturing support device M is based on the cylinder manufacturing support device M in the first embodiment. The upper pressing mechanism 20, the first transverse pressing mechanism 20a, and the second transverse pressing mechanism 20b each have a base 21 and a front end 22 that can move relative to the base 21 along the front end moving direction. The base 21 of the upper pressing mechanism 20 is mounted on the upper beam 12 such that the front end moving direction has a component of the vertical direction Dv and the front end 22 of the upper pressing mechanism 20 faces downwards. The base 21 of the first transverse pressing mechanism 20a is mounted on the first column 11a such that the front end moving direction has a component of the transverse direction Ds and the front end 22 of the first transverse pressing mechanism 20a faces the side of the second column 11b. The base 21 of the second transverse pressing mechanism 20b is mounted on the second column 11b such that the front end moving direction has a component of the transverse direction Ds and the front end 22 of the second transverse pressing mechanism 20b faces the side of the first column 11a.

[0159] (3) The cylinder manufacturing support device M in the third embodiment is based on the cylinder manufacturing support device M in the second embodiment. The cylinder manufacturing support device includes: a first base support frame 40a, which supports the base 21 of the first transverse pressing mechanism 20a and is mounted on the first column 11a in a manner that allows it to move along the vertical direction Dv; a first support frame moving mechanism 50a, which allows the first base support frame 40a to move along the vertical direction Dv; a second base support frame 40b, which supports the base 21 of the second transverse pressing mechanism 20b and is mounted on the second column 11b in a manner that allows it to move along the vertical direction Dv; and a second support frame moving mechanism 50b, which allows the second base support frame 40b to move along the vertical direction Dv.

[0160] In cylinder 1, there are cases where the cylinder axis At is bent, and the external dimensions and shape of cylinder 1 differ depending on the position of the cylinder axis direction Da. In this solution, even in such cases, by moving the first lateral pressing mechanism 20a and the second lateral pressing mechanism 20b along the vertical direction Dv, the temporary assembly plate group 9 can be clamped in the movement restriction step S6 using the front end 22 of the first lateral pressing mechanism 20a and the front end 22 of the second lateral pressing mechanism 20b.

[0161] (4) In the fourth embodiment, the cylinder manufacturing support device M is based on the cylinder manufacturing support device M in the third embodiment. The first base support frame 40a supports the base 21 of the first transverse pressing mechanism 20a so that it can swing about a swing axis 43 extending along the depth direction Dl. The second base support frame 40b supports the base 21 of the second transverse pressing mechanism 20b so that it can swing about a swing axis 43 extending along the depth direction Dl. The cylinder manufacturing support device includes: a first base swing mechanism 45a, which is mounted on the first base support frame 40a and is capable of swinging the base 21 of the first transverse pressing mechanism 20a about the swing axis 43 of the first base support frame 40a; and a second base swing mechanism 45b, which is mounted on the second base support frame 40b and is capable of swinging the base 21 of the second transverse pressing mechanism 20b about the swing axis 43 of the second base support frame 40b.

[0162] In cylinder 1, there are cases where the cylinder axis At is bent, and the external dimensions and shape of cylinder 1 differ depending on the position of the cylinder axis direction Da. In this solution, even under such circumstances, by swinging the first lateral pressing mechanism 20a and the second lateral pressing mechanism 20b, the movement and tilting of the temporary assembly plate group 9 in the movement restriction process S6 can be stably restricted.

[0163] (5) The fifth embodiment of the cylinder manufacturing support device M is based on the cylinder manufacturing support device M in any of the first to fourth embodiments, wherein the slider 60 has: a pair of roller guides 61 extending along the depth direction D1 and disposed at intervals between the first post 11a and the second post 11b on the transverse direction Ds; and a plurality of rollers 62 arranged along the depth direction D1 and disposed between the pair of roller guides 61, and supported on the pair of roller guides 61 in a manner that allows them to rotate about the axis of the rollers 62 extending along the transverse direction Ds.

[0164] (6) The sixth embodiment of the tube manufacturing support device M is based on the tube manufacturing support device M of any of the first to fifth embodiments, wherein the portion of the upper beam 12 including the range in which the upper pressing mechanism 20 can move along the transverse Ds is bent such that as the upper beam 12 approaches the center of the transverse Ds from the first column 11a, it gradually moves toward the vertical upper side and as the upper beam 12 approaches the center from the second column 11b.

[0165] The multiple metal plates 3 constituting the cylinder 1 are all substantially bent. In this design, the upper beam 12 includes a portion that allows the upper pressing mechanism 20 to move laterally by Ds, thus enabling the front end 22 of the upper pressing mechanism 20 to move in the appropriate direction relative to the front end of the base 21 of the upper pressing mechanism 20, relative to the bent metal plates 3.

[0166] The manufacturing method of cylinder 1 in the above-described embodiments and variations is as follows.

[0167] (7) Regarding the manufacturing method of the cylinder 1 in the seventh embodiment, the cylinder 1 is manufactured using the cylinder manufacturing support device M in any one of the first to sixth embodiments.

[0168] The manufacturing method includes: a preparation step S1, preparing the plurality of metal plates 3, a first auxiliary metal plate 71a corresponding to the internal dimensions and internal shape of the first side Da1 of the cylinder 1 in the first axis Da1 and the second side Da2 of the cylinder axis direction Da, and a second auxiliary metal plate 71b corresponding to the internal dimensions and internal shape of the second side Da2 of the cylinder 1 in the first axis Da1 and the second side Da2 of the cylinder axis direction Da; and a temporary joining step S2, to fix the relative positions of the first metal plate 3a and the third metal plate 3c, which are opposed to each other across the cylinder axis At among the plurality of metal plates 3. In the process of connecting the first metal plate 3a and the third metal plate 3c after the completion of the cylinder 1, the first metal plate 3a and the third metal plate 3c are temporarily joined to a portion of the edge 6 of the first auxiliary metal plate 71a and a portion of the edge 6 of the second auxiliary metal plate 71b, respectively; in the placement process S3, the first metal plate 3a and the third metal plate 3c, temporarily joined to the first auxiliary metal plate 71a and the second auxiliary metal plate 71b, are placed on the slider 60 such that the cylinder axis At extends along the depth direction D1; in the joining plate configuration process S4, the first metal plate 3a and the third metal plate 3c, which are temporarily joined to the first auxiliary metal plate 71a and the second auxiliary metal plate 71b, are placed on the slider 60. The edge 6 of the second metal plate 3b, excluding the first metal plate 3a and the third metal plate 3c, extending in the circumferential direction Dc and in the cylindrical axis direction Da, is adjacent to the edge 6 of one of the metal plates 3a and 3c that are temporarily joined to the first auxiliary metal plate 71a and the second auxiliary metal plate 71b, extending in the circumferential direction Dc and in the cylindrical axis direction Da; Position adjustment step S5, so that the predetermined engagement position of the edge 6 of the second metal plate 3b relative to the edge 6 of the one metal plate 3 in the cylindrical axis direction Da becomes located on the upper beam 12. The temporary assembly plate group 9, which is a collection of the first auxiliary metal plate 71a, the second auxiliary metal plate 71b, the first metal plate 3a, the second metal plate 3b, and the third metal plate 3c, is moved along the depth direction D1 on the slider 60 in a way that adjusts the position of the temporary assembly plate group 9; in the movement restriction step S6, the first lateral pressing mechanism 20a and the second lateral pressing mechanism 20b are operated to clamp the temporary assembly plate group 9 located in the working position and restrict the movement of the temporary assembly plate group 9;Edge-aligning processing step S7: During the execution of the movement-restricting step S6, the upper pressing mechanism 20 presses a portion of one of the edges 6 extending along the cylinder axis direction Da of the metal plate 3 and a portion of the edges 6 extending along the cylinder axis direction Da of the second metal plate 3b, so that the portion of the edge 6 of the metal plate 3 and the portion of the edge 6 of the second metal plate 3b are aligned in the circumferential direction Dc; Joining step S8: During the execution of the movement-restricting step S6 and the edge-aligning processing step S7, the portion of the edge 6 of the metal plate 3 and the portion of the edge 6 of the second metal plate 3b are joined; and auxiliary plate removal step S11: After the plurality of metal plates 3 are connected to each other, the first auxiliary metal plate 71a and the second auxiliary metal plate 71b are removed from the first metal plate 3a and the third metal plate 3c. The position adjustment process S5, the movement restriction process S6, the edge alignment process S7, and the joining process S8 are repeated until the entire edge 6 of the second metal plate 3b extending in the cylindrical axial direction Da is joined to the edge 6 of one of the metal plates 3.

[0169] In the manufacturing method of cylinder 1 in this scheme, since the cylinder manufacturing support device M of the above scheme is used, the burden on the operator can be reduced when manufacturing the cylinder.

In the edge-aligning process, during the execution of the movement restriction process, the upper pressing mechanism is used to press a portion of one of the edges of the first metal plate extending along the direction of the cylinder axis and a portion of the edge of the second metal plate extending along the direction of the cylinder axis, so that the portion of the edge of the first metal plate is aligned with the portion of the edge of the second metal plate in the circumferential direction. In the joining process, during the execution of the movement restriction process and the edge alignment process, a portion of the edge of one metal plate is joined to a portion of the edge of the second metal plate; and In the auxiliary plate removal process, after the plurality of metal plates are connected to each other, the first auxiliary metal plate and the second auxiliary metal plate are removed from the first metal plate and the third metal plate. The position adjustment process, the movement restriction process, the edge alignment process, and the joining process are repeated until the entire edge of the second metal plate extending in the direction of the cylinder axis is joined to the edge of the one metal plate.
