[0005] Patent Literature 1: Japanese Patent No. 4035901 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] The plate processing system of Patent Literature 1 transports the plate in the left-right direction between the loading table that is disposed on the right side or the left side of the processing machine and the table of the processing machine by the loading device. Thus, it is necessary to ensure a wide space for the loading table and a space for a guide rail of the loading device and the like on the right side or the left side of the processing machine. However, if the loading table and the loading device are disposed on the right side or the left side of the processing machine, other devices cannot be disposed adjacent to the right side or the left side of the processing machine, and the space efficiency in a building is not good. Further, in a case where other devices and the like are already disposed adjacent to the left side and the right side of the processing machine in a building, there is a problem that the loading table and the loading device cannot be disposed with respect to the processing machine. Further, the front side of the processing machine is sometimes set to include a space that can be used as a passage for an operator, and it is required to effectively utilize the space.

[0008] An object of the present application is to provide a plate processing system that does not require a space for disposing a loading table and a loading device on the right side and the left side of a processing machine, and can effectively utilize a space on the front side of the processing machine.

[0009] MEANS FOR SOLVING THE PROBLEMS

[0010] The plate processing system according to the aspect of the present application includes a processing machine that processes a processing site of a plate at a processing position, a loading device that transports the plate between a table on which the plate is placed and the processing machine, the processing machine includes a table on which the plate is placed, a carriage that is provided so as to extend in a left-right direction and is movable in a front-rear direction, and a slider that holds the plate and is guided by the carriage so as to be movable in the left-right direction, the plate held by the slider is moved on the table by at least one of movement of the carriage in the front-rear direction and movement of the slider in the left-right direction, and the processing site of the plate is positioned with respect to the processing position, the table is disposed on a front side of the processing machine in the front-rear direction, and the loading device includes a guide rail that extends in the front-rear direction above the carriage, a movable member that is guided by the guide rail so as to be movable in the front-rear direction, and a suction head that is provided to the movable member so as to be able to be raised and lowered and is able to suction the plate, and the plate suctioned by the suction head is transported between the table and the table.

[0011] Effects of Invention

[0012] According to the plate processing system described above, the table is disposed on the front side of the processing machine in the front-rear direction, the suction head of the loading device is moved along the guide rail that extends in the front-rear direction above the carriage, and thus the plate is transported between the table and the table, and therefore, it is not necessary to secure a space for disposing the table and the loading device on the right side and the left side of the processing machine. As a result, it is possible to dispose other devices adjacent to the right side and the left side of the processing machine, and it is possible to improve the space efficiency in a building. Furthermore, the table and a part of the loading device are disposed on the front side of the processing machine, and therefore, it is possible to effectively utilize the space on the front side of the processing machine.

[0013] Furthermore, in the plate processing system described above, the suction head can include a first suction head that is used to carry an unprocessed plate from the table to the processing machine, and a second suction head that is used to carry a processed plate from the processing machine to the table. According to this configuration, it is possible to efficiently transport the unprocessed plate and the processed plate. Furthermore, the first suction head and the second suction head can be integrally movable in the front-rear direction. According to this configuration, it is possible to easily control movement of the first suction head and the second suction head in the front-rear direction. Furthermore, in the plate processing system described above, the first suction head and the second suction head can be independently raisable and lowerable. According to this configuration, it is possible to suction or release the unprocessed plate and the processed plate at appropriate timings, respectively.

[0014] Further, in the above-described board processing system, the first and second suction heads can be arranged in the front-rear direction, and the first and second placement portions can be arranged in the front-rear direction in the placement table. The first placement portion can place the unprocessed board sucked by the first suction head, and the second placement portion can place the processed board sucked by the second suction head. According to this configuration, the unprocessed board and the processed board can be efficiently transported by matching the arrangement of the first and second suction heads with the arrangement of the first and second placement portions. Further, in the above-described board processing system, the interval of the first and second suction heads in the front-rear direction can be set in accordance with the interval of the first and second placement portions in the front-rear direction. According to this configuration, the unprocessed board and the processed board can be simultaneously or almost simultaneously sucked or released. Further, in the above-described board processing system, the first placement portion can include a positioning member that is brought into contact with an edge portion of the unprocessed board placed thereby to position the board. According to this configuration, the unprocessed board can be easily positioned with respect to the first suction head.

[0015] Further, in the above-described board processing system, the placement table can be guided by a rail arranged in the left-right direction and can be moved between an entry position below the rail and a retreat position away from below the rail. According to this configuration, by moving the placement table to the retreat position, the unprocessed board can be easily replenished to the placement table or the processed board can be easily recovered. Further, in the above-described board processing system, the placement table can be arranged such that an upper placement table and a lower placement table overlap in the up-down direction, and the upper and lower placement tables can be guided by rails and can be moved in the left-right direction. According to this configuration, by switching the use of the two placement tables, the unprocessed board can be efficiently replenished and the processed board can be efficiently recovered.

[0016] Further, in the above-described board processing system, either one of the upper and lower placement tables can place the unprocessed board sucked by the suction head, and the other can place the processed board sucked by the suction head. According to this configuration, the unprocessed board and the processed board can be distinguished and placed on the two placement tables, and thus the unprocessed board can be more efficiently replenished and the processed board can be more efficiently recovered. Further, in the above-described board processing system, the processing machine can include a punch mechanism or a laser head at the processing position. According to this configuration, the right and left sides of the processing machine including the punch mechanism or the laser head at the processing position do not need to be provided with space for the placement table or the like.

[0034] Hereinafter, embodiments will be described with reference to the drawings. However, the present application is not limited to the embodiments described below. Furthermore, in order to illustrate the embodiments in the drawings, the scale is appropriately changed to be represented by enlarging or emphasizing a part or the like, and sometimes the shape and size are different from those of the actual product. In each of the following drawings, the directions in the drawings are illustrated using an XYZ coordinate system. In the XYZ coordinate system, the up-down direction (vertical direction) is set as the Z direction, and the X direction and the Y direction are set along the horizontal plane. The X direction is the left-right direction D1 in the horizontal plane, and the Y direction is the front-rear direction D2 in the horizontal plane. Furthermore, with respect to each of the X, Y, and Z directions, the direction indicated by the arrow is represented as the + direction (for example, the +X direction, the +X side), and the opposite direction of the direction indicated by the arrow is represented as the - direction (for example, the -X direction, the -X side).

[0035] Figure 1 is a perspective view of the sheet processing system SYS of the embodiment as viewed from above the front side. Figure 2 is a plan view of the sheet processing system SYS as viewed from the upper side (+Z side). Figure 3 is a side view of the sheet processing system SYS as viewed from the -X side in the left-right direction D1. Figure 4 is a front view of the sheet processing system SYS as viewed from the +Y side in the front-rear direction D2. In the present embodiment, the +X side is the left side in the left-right direction D1, and the -X side is the right side in the left-right direction D1. Furthermore, the +Y side is the front side in the front-rear direction D2, and the -Y side is the rear side in the front-rear direction D2.

[0036] As shown in Figures 1 to 4 , the sheet processing system SYS is provided with a processing machine 101 and a loading device 102. The processing machine 101 is, for example, a press working machine that performs press working on a working site of a workpiece (sheet) W1 at a processing position P1. The processing machine 101 has a press mechanism 10, a press frame 20, and a conveying device 30. In the present embodiment, unprocessed workpieces (sheets) are denoted as workpieces W1, and processed workpieces are denoted as workpieces W2. Furthermore, the space on the front side (+Y side) in the front-rear direction D2 of the sheet processing system SYS (processing machine 101) is used, for example, as a passage for an operator or the like, a conveying path for carrying in and out the workpieces W1, W2 with respect to the sheet processing system SYS, or the like, and no other device is provided.

[0037] The press mechanism 10 has an upper turret 11 and a lower turret 12. That is, the processing machine 101 is a turret press. The upper turret 11 is held to an upper side press frame portion 22 of the press frame 20 via a rotation shaft 13. The lower turret 12 is held to a lower side press frame portion 21 of the press frame 20 via a rotation shaft 14. The upper turret 11 and the lower turret 12 are each formed in a disc shape. The upper turret 11 and the lower turret 12 are each formed so as to be able to rotate with the rotation shaft 13 and the rotation shaft 14 as an axis by driving a driving device such as an electric motor, which is not shown. The upper turret 11 and the lower turret 12 are disposed in a state of facing each other.

[0038] The upper turret 11 holds upper side press tools 15 such as punches. On the upper turret 11, a plurality of the upper side press tools 15 are arranged and disposed in a direction of rotation centered on the rotation shaft 13. A lower surface side of the upper side press tool 15 functions as a blade or a molding portion and processes the workpiece W1. The upper turret 11 drives the upper side press tool 15 in the up-and-down direction (Z direction). A head 17 that feeds out the upper side press tool 15 downward is disposed on the upper turret 11.

[0039] The lower turret 12 holds lower side press tools 16 such as dies. On the lower turret 12, a plurality of the lower side press tools 16 are arranged and disposed in a direction of rotation centered on the rotation shaft 14. The lower side press tools 16 are disposed at intervals below (−Z direction) the upper side press tools 15. The lower side press tool 16 is, for example, a member that is cylindrical or concave with the Z direction as an axis direction, and a top surface side thereof functions as a blade or a molding portion and processes the workpiece W1. The lower side press tool 16 can be configured to be fixed in the up-and-down direction (Z direction) at the time of processing of the workpiece W1, or can be configured to be fed out upward by a driving portion, which is not shown.

[0040] The upper turret 11 and the lower turret 12 are each rotated by a driving device, which is not shown, to select a pair of a group of the upper side press tool 15 and the lower side press tool 16 to a processing position P1. The press mechanism 10 disposes a processing target portion that is a part of the workpiece W1 at the processing position P1, feeds out the upper side press tool 15 downward by the head 17 or feeds out the upper side press tool 15 downward and feeds out the lower side press tool 16 upward, and clamps a processing site of the workpiece W1 by the upper side press tool 15 and the lower side press tool 16, whereby the processing site of the workpiece W1 is subjected to hole processing, molding processing, or cutting processing, or the like.

[0041] The press frame 20 supports the press mechanism 10. The press frame 20 has a lower side press frame portion 21, an upper side press frame portion 22, and a longitudinal press frame portion 23. The lower side press frame portion 21 is provided on, for example, the floor of a building. Further, the lower side press frame portion 21 supports the lower turret 12 that is a part of the press mechanism 10. The upper side press frame portion 22 is located above the conveying space K of the workpieces Wl, W2 with respect to the lower side press frame portion 21. The upper side press frame portion 22 supports the upper turret 11. The longitudinal press frame portion 23 links the lower side press frame portion 21 and the upper side press frame portion 22.

[0042] Further, the press frame 20 has a fixed table (table) 24. The fixed table 24 is provided to the lower side press frame portion 21. The fixed table 24 is disposed at a height between the upper turret 11 and the lower turret 12. In addition, a brush, a free ball bearing, or the like can be provided to the upper surface of the fixed table 24 to reduce friction with the lower surface side of the workpieces Wl, W2.

[0043] The conveying device 30 is provided to the lower side press frame portion 21 of the press frame 20. The conveying device 30 has movable tables (tables) 31, carriages 32, Y guides 33, sliders 34, and workpiece holders 35. The movable tables 31 are disposed on the left (+X side) and the right (-X side) of the fixed table 24, respectively. The two movable tables 31 are, for example, linked to each other on the +Y side, integrated by a drive portion not shown, and movable in the front-rear direction D2 (Y direction) by the Y guides 33. The Y guides 33 guide the two movable tables 31 in the front-rear direction D2. The Y guides 33 are provided to the lower side press frame portion 21, but are not limited to this configuration and can be provided to the floor on which the processing machine 101 is provided. A brush, a free ball bearing, or the like can be provided to the upper surface of the movable tables 31 to reduce friction with the lower surface side of the workpieces Wl, W2.

[0044] The carriage 32 extends in the left-right direction D1 (X direction) and is provided at the end of the movable table 31 on the front side (+Y side) via a connecting member such as an arm, which is not shown. Thus, the carriage 32 moves in the front-rear direction D2 integrally with the movable table 31. In other words, the movable table 31 moves in the front-rear direction D2 together with the carriage 32 by the movable table 31 moving in the front-rear direction D2 by the carriage 32. The carriage 32 functions as a connecting member that links the movable table 31 on the left side and the movable table 31 on the right side. The carriage 32 is provided at a position higher than the fixed table 24. Thus, when the carriage 32 moves in the front-rear direction D2, it does not interfere with the fixed table 24. In addition, in the present embodiment, the movable table 31 moves in the front-rear direction D2 integrally with the carriage 32, but it is not limited to this manner. For example, in the case where the processing machine 101 does not have the movable table 31 (i.e., in the case where the fixed table 24 extends to the area of the movable table 31 in plan view, etc.), a manner in which the carriage 32 moves in the front-rear direction D2 relative to the fixed table 24 can also be used.

[0045] The slide 34 is provided on the rear side (-Y side) of the carriage 32. The slide 34 is movable in the left-right direction D1 (X direction) along the carriage 32 by a drive section, which is not shown. The slide 34 has a plurality of (three in the present embodiment) workpiece holders 35. The plurality of workpiece holders 35 are arranged at a plurality of predetermined intervals in the left-right direction D1 on the rear side of the slide 34 and hold the end portions of the +Y sides of the workpieces W1, W2. In addition, the workpiece holders 35 can be movable in the X direction relative to the slide 34. By the carriage 32 moving in the front-rear direction D2 together with the movable table 31 and the slide 34 moving in the left-right direction D1 relative to the carriage 32, the workpieces W1, W2 held by the workpiece holders 35 can be moved in the horizontal plane in the left-right direction D1 and the front-rear direction D2.

[0046] The drive of each part of the above-described processing machine 101 is controlled by the control section C. The control section C drives each part of the conveying device 30 and moves the workpiece W1 held by the workpiece holders 35 on the fixed table 24 or the movable table 31 by at least one of the movement of the carriage 32 in the front-rear direction D2 and the movement of the slide 34 in the left-right direction D1, and positions the processing site of the workpiece W1 relative to the processing position P1. In addition, the control section C drives each part of the press mechanism 10 and performs press processing on the processing site of the workpiece W1. In addition, for the drive of each part in the processing machine 101, manual operation by an operator can be performed instead of the control by the control section C.

[0047] The loading device 102 conveys the workpiece W between the placement table 103 on which the workpiece W can be placed and the machining machine 101. The placement table 103 is disposed on the front side (+Y side) of the machining machine 101 in the front-rear direction D2 (Y direction). The placement table 103 has an upper placement table 61 and a lower placement table 62. The upper placement table 61 and the lower placement table 62 are disposed so as to overlap in the vertical direction on the front side of the machining machine 101. The upper placement table 61 and the lower placement table 62 are each guided by a rail 63, 64 disposed along the left-right direction D1 so as to be movable in the left-right direction D1. The upper placement table 61 and the lower placement table 62 are movable between an entry position P3 below the guide rail 41 described later and a retreat position P4 away from below the guide rail 41.

[0048] The upper placement table 61 has a first placement section 61a and a second placement section 61b. The first placement section 61a places unprocessed workpieces W1 in a stacked state. The second placement section 61b places processed workpieces W2 processed by the machining machine 101 in a stacked state. The workpieces W1, W2 shown in the present embodiment are long strip-shaped materials that are longer in the left-right direction D1 and shorter in the front-rear direction D2.

[0049] The first placement section 61a and the second placement section 61b are arranged in the front-rear direction D2. The first placement section 61a is disposed on the rear side in the front-rear direction D2, and the second placement section 61b is disposed on the front side in the front-rear direction D2. Alternatively, the first placement section 61a and the second placement section 61b can be arranged in the opposite configuration in the front-rear direction D2. The upper placement table 61 has a positioning member 61c in the first placement section 61a. The positioning member 61c positions the stacked unprocessed workpieces W1 in the first placement section 61a by abutting against the edge portions of the plurality of unprocessed workpieces W1 placed in the first placement section 61a.

[0050] The loading device 102 has a rail mechanism 40 and a moving mechanism 50. The rail mechanism 40 has a guide rail 41 and two support columns 42. The guide rail 41 guides the moving mechanism 50. The guide rail 41 is disposed so as to extend above the carriage 32 in the front-rear direction D2. The guide rail 41 is disposed on the right side (+X side) of the press frame 20 in the front-rear direction D2 in plan view. The guide rail 41 is disposed so as to span the right movable table 31 and the placement table 103 in the front-rear direction D2. The two support columns 42 are disposed respectively on the rear side (-Y direction) of the right movable table 31 and on the front side (+Y direction) of the carriage 32 (placement table 103). The support columns 42 support the end portions of the guide rail 41 on the rear side and the front side, respectively.

[0051] The moving mechanism 50 has a movable member 51, a lifting rod 52, and a suction head 53. The movable member 51 is guided by the rail 41 and moves in the front-rear direction D2 (Y direction) by a driving mechanism not shown. As the driving mechanism, for example, a rack-and-pinion mechanism using an electric rotary motor, a ball screw mechanism, a linear motor, or the like is used. The movable member 51 is disposed on the rail 41 and moves in the front-rear direction D2 in a state of being supported by the rail 41. In addition, the movable member 51 can also be a manner in which a traveling wheel is provided to be rotationally driven by an electric motor or the like as the driving mechanism, and moves on the rail 41 in the front-rear direction D2 by rotationally driving the traveling wheel. The movable member 51 has portions protruding to the left and right sides with respect to the rail 41.

[0052] The lifting rod 52 is a rod-shaped body extending in the up-down direction (Z direction). The lifting rod 52 is supported by the movable member 51 in a state of being able to move in the up-down direction. The lifting rod 52 is provided on the front side and the rear side of the portions of the movable member 51 protruding to the left and right sides from the rail 41. The lifting rod 52 is lifted with respect to the movable member 51 by a driving mechanism not shown. As the driving mechanism, for example, a rack-and-pinion mechanism using an electric rotary motor, a ball screw mechanism, a linear motor, or the like is used.

[0053] The lifting rod 52 has two first lifting rods 52a provided on the rear side of the movable member 51, and two second lifting rods 52b provided on the front side of the movable member 51. The two first lifting rods 52a are respectively disposed on the left side and the right side on the rear side of the movable member 51. Both of the two first lifting rods 52a are integrally lifted. The two second lifting rods 52b are respectively disposed on the left side and the right side on the front side of the movable member 51. Both of the two second lifting rods 52b are integrally lifted. The lifting of the first lifting rod 52a and the lifting of the second lifting rod 52b can be independently performed. That is, the driving mechanism that lifts the first lifting rod 52a and the driving mechanism that lifts the second lifting rod 52b are separately provided.

[0054] The suction head 53 has a plurality of suction pads on the lower surface side, and can suction the workpieces W1, W2 by the suction pads. The suction head 53 has two first suction heads 53a provided on the lower ends of the two first lifting rods 52a, and two second suction heads 53b provided on the lower ends of the two second lifting rods 52b.

[0055] The first suction head 53a suctions the unprocessed workpiece Wl when the unprocessed workpiece Wl placed on the first placement portion 61a of the placement table 103 is carried into the processing machine 101. The first suction head 53a is raised and lowered together with the first lifting rod 52a. The second suction head 53b suctions the processed workpiece W2 when the processed workpiece W2 is carried out of the processing machine 101. The second lifting rod 52b is raised and lowered together with the second lifting rod 52b. Further, the first suction head 53a and the second suction head 53b are moved in the front-rear direction D2 integrally with the movable member 51 via the first lifting rod 52a and the second lifting rod 52b, respectively.

[0056] The first suction head 53a and the second suction head 53b are arranged in the front-rear direction D2 (Y direction). The arrangement of the first suction head 53a and the second suction head 53b corresponds to the arrangement of the first placement portion 61a and the second placement portion 61b. That is, the first suction head 53a is arranged on the rear side of the movable member 51 in correspondence with the first placement portion 61a arranged on the rear side in the front-rear direction D2, and the second suction head 53b is arranged on the front side of the movable member 51 in correspondence with the second placement portion 61b arranged on the front side in the front-rear direction D2.

[0057] Further, the interval V of the first suction head 53a and the second suction head 53b in the front-rear direction D2 is set in accordance with the interval of the first placement portion 61a and the second placement portion 61b in the front-rear direction D2. That is, the interval V of the first suction head 53a and the second suction head 53b is set so that, in a state where the movable member 51 is held at a prescribed position in the front-rear direction D2, the first suction head 53a is positioned above the first placement portion 61a and the second suction head 53b is positioned above the second placement portion 61b. As a result, the state where the movable member 51 is held at the prescribed position in the front-rear direction D2 is maintained, and the first suction head 53a and the second suction head 53b are lowered, whereby the unprocessed workpiece Wl on the first placement portion 61a can be suctioned by the first suction head 53a, and the processed workpiece W2 can be placed on the second placement portion 61b by the second suction head 53b.

[0058] The driving of each portion of the loading device 102 is controlled by the control section C. The control section C drives each portion of the loading device 102 to transport the unprocessed workpiece Wl from the first placement portion 61a to the processing machine 101, and to transport the processed workpiece W2 from the processing machine 101 to the second placement portion 61b. Alternatively, the driving of each portion in the loading device 102 can be performed by manual operation by an operator instead of the control by the control section C. Further, in the present embodiment, the processing machine 101 and the loading device 102 are controlled by one control section C, but the present application is not limited to this mode, and for example, the control section C can be formed separately as a control section that controls the processing machine 101 and a control section that controls the loading device 102.

[0059] Thus, according to the sheet processing system SYS of the present embodiment, the placement table 103 is arranged at the front side of the processing machine 101 in the front-rear direction D2, and the loading device 102 moves along the guide rail 41 extending above the carriage 32 in the front-rear direction D2, whereby the workpieces W1, W2 are transported between the fixed table 24 and the movable table 31 and the placement table 103. As a result, no space for arranging the placement table 103 and the loading device 102 is required at the right and left sides of the processing machine 101, other devices can be arranged adjacent to the right and left sides of the processing machine 101, and the space efficiency in the building can be improved. Further, since the placement table 103 and a part of the loading device 102 are arranged at the front side of the processing machine 101, the space at the front side of the processing machine 101 can be effectively utilized.

[0060] Further, as shown in Figure 2 , the processing machine 101 can also be provided with a laser head 36 in addition to the punching mechanism 10. The laser head 36 irradiates laser light toward a processing site of the workpiece W1, and performs cutting or hole formation of the processing site, or the like. The laser head 36 is supported by a guide member (not shown) so as to be movable in the front-rear direction D2 (Y direction). By the movement of the laser head 36 in the front-rear direction D2 and the movement of the workpiece W1 in the left-right direction D1 by the transport device 30, the processing site of the workpiece W1 can be arranged at an irradiation position at which the laser head 36 irradiates laser light.

[0061] Next, the operation of the sheet processing system SYS of the present embodiment will be described. Figures 5 to 12 An example of the operation of the sheet processing system SYS will be described, mainly focusing on the operation of the loading device 102. Figure 5 is a view showing a state in which the loading device 102 transports the unprocessed workpiece W1 from the placement table 103 and places it in the processing machine 101. As shown in Figure 5 , the loading device 102 carries the workpiece W1 into the processing machine 101. First, the control section C moves the movable member 51 in the front-rear direction D2 to arrange it above the placement table 103. At this time, the position of the movable member 51 is set so that the first suction head 53a is positioned above the first placement portion 61a.

[0062] Next, the control unit C lowers the first lifting rod 52a, causing the first suction head 53a to descend until it reaches the upper surface of the uppermost workpiece W1 among the unprocessed workpieces W1 stacked on the first mounting unit 61a. Afterwards, the control unit C, having suctioned the workpiece W1 via the first suction head 53a, raises the first suction head 53a, causing the movable member 51 to move rearward (in the -Y direction) in the forward-backward direction D2, thus positioning the first suction head 53a (workpiece W1) above the loading / unloading position P2 of the processing machine 101. The loading / unloading position P2 is, for example, set at a position spanning the fixed worktable 24 and the movable worktable 31 on the right side (see reference). Figure 2 ), then, as Figure 5 As shown, the control unit C lowers the first adsorption head 53a, placing the workpiece W1 at the transfer-in / transfer-out position P2 and releasing the adsorption. Through this action, the unprocessed workpiece W1 is transferred into the transfer-in / transfer-out position P2 of the processing machine 101. The control unit C then raises the first adsorption head 53a, which has released its adsorption, and retracts it from the transfer-in / transfer-out position P2.

[0063] Next, the control unit C drives the conveyor 30 of the machining machine 101 so that the workpiece holder 35 holds the +Y side end of the workpiece W1. The machining machine 101 performs stamping processing on the workpiece W1. The control unit C performs stamping processing on the processing part of the workpiece W1, for example, based on a preset processing program.

[0064] Figure 6 This diagram illustrates the state of workpiece W1 being processed by machining machine 101. For example... Figure 6 As shown, the machining machine 101 moves the workpiece W1 in one or both of the left-right direction D1 and the front-back direction D2 via the carriage 32 (movable worktable 31) and the slider 34, positioning the machining area of ​​the workpiece W1 at machining position P1. The machining machine 101 rotates the upper turret 11 and the lower turret 12 to select the upper stamping tool 15 and the lower stamping tool 16 for stamping, respectively, and positions them at machining position P1. Next, the machining machine 101 lowers the head 17, sending the upper stamping tool 15 downwards. The upper and lower stamping tools 15 and 16 then clamp the machining area of ​​the workpiece W1, performing stamping operations (such as hole drilling, forming, or cutting). The machining machine 101 performs stamping operations on multiple machining areas of the workpiece W1 by repeatedly performing this series of actions. After stamping, the machined workpiece W2 is positioned at the loading / unloading position P2.

[0065] Furthermore, when the processing machine 101 is equipped with a laser head 36 (see reference) Figure 2), the workpiece W1 can be subjected to laser processing using laser light emitted from the laser head 36 after or before the workpiece W1 is subjected to press processing by the press mechanism 10. This laser processing is performed by emitting laser light from the laser head 36 and moving the laser head 36 relative to the workpiece W1 to cut or perforate the processing site. For example, the laser head 36 is moved in the front-rear direction D2, and the workpiece W1 is moved in the left-right direction Dl by the conveyance device 30, whereby the processing site of the workpiece W1 is positioned at the laser light irradiation position of the laser head 36, laser light is emitted from the laser head 36, and laser processing is performed.

[0066] In parallel with the press processing or laser processing of the workpiece W1 by the processing machine 101 (during the press processing or laser processing), the control section C, as described above, moves the movable member 51 in the -Y direction of the front-rear direction D2 after the unprocessed workpiece W1 on the first placement portion 61a is adsorbed by the first adsorption head 53a. Figure 7 is a view showing a state in which the next unprocessed workpiece W1 is conveyed by the loading device 102. As shown in Figure 7 , the control section C positions the movable member 51 at a prescribed position in the front-rear direction D2 so that the second adsorption head 53b is positioned above the processed workpiece W (above the in-out position P2).

[0067] Next, the control section C lowers the second adsorption head 53b. At this time, the state becomes one in which the processed workpiece W2 is positioned above the in-out position P2 of the processing machine 101, and the workpiece holder 35 is separated from the workpiece W2 to the +Y side. In addition, the first adsorption head 53a is not lowered but waits above the processing machine 101 in a state in which the workpiece W1 is held. Figure 8 is a view showing a state in which the processed workpiece W2 is adsorbed by the loading device 102. As shown in Figure 8 , the control section C adsorbs the processed workpiece W2 by the second adsorption head 53b after lowering the second adsorption head 53b until the upper surface of the processed workpiece W2 is reached. Thereafter, the control section C raises the second adsorption head 53b to which the workpiece W2 is adsorbed.

[0068] Next, the control section C moves the movable member 51 in the +Y direction of the front-rear direction D2 to position the first adsorption head 53a to which the unprocessed workpiece W2 is adsorbed above the in-out position P2. Thereafter, the control section C lowers the first adsorption head 53a. Figure 9 is a view showing a state in which the next unprocessed workpiece W1 is placed on the processing machine 101 by the loading device 102. As shown in Figure 9As shown, the control section C lowers the first adsorption head 53a, places the workpiece Wl at the carrying-in / out position P2, and releases the adsorption. By this action, the next unprocessed workpiece Wl is carried into the carrying-in / out position P2 of the processing machine 101. At this time, the second adsorption head 53b does not lower and waits above the processing machine 101 in a state of holding the workpiece W2. After that, the control section C raises the first adsorption head 53a and retreats from the carrying-in / out position P2.

[0069] The workpiece Wl placed at the carrying-in / out position P2 is held by the workpiece holder 35 at the end portion on the +Y side as with the above, and is conveyed by the conveying device 30 as shown. Figure 6 The workpiece Wl is subjected to press processing at a plurality of processing sites at the processing position PI.

[0070] In parallel with the press processing of this workpiece Wl (during the press processing), the control section C moves the movable member 51 in the +Y direction of the front-rear direction D2, and configures the adsorption head 53 above the placement table 103. Figure 10 is a view showing a state in which the processed workpiece W2 is conveyed by the loading device 102. As shown, Figure 10 the control section C moves the movable member 51 and configures the movable member 51 such that the first adsorption head 53a is positioned above the first placement portion 61a and the second adsorption head 53b is positioned above the second placement portion 61b. At this time, the second adsorption head 53b holds the workpiece W2 and the first adsorption head 53a does not hold the workpiece Wl.

[0071] Next, the control section C lowers both the first adsorption head 53a (the first lifting rod 52a) and the second adsorption head 53b (the second lifting rod 52b). Figure 11 is a view showing a state in which the processed workpiece W2 is placed on the placement table 103 by the loading device 102 and the next unprocessed workpiece Wl is adsorbed. As shown, Figure 11 the control section C lowers both the first adsorption head 53a and the second adsorption head 53b at the same time or almost at the same time. In addition, it is not limited to the case in which the first adsorption head 53a and the second adsorption head 53b are lowered at the same time or almost at the same time. For example, the control section C can lower either of the first adsorption head 53a and the second adsorption head 53b first, and lower the other after or during the lowering.

[0072] The first adsorption head 53a is lowered until the upper surface of the uppermost workpiece Wl among the unprocessed workpieces Wl is reached, and the uppermost workpiece Wl is adsorbed. The second adsorption head 53b is lowered until the adsorbed processed workpiece W2 reaches the second placement portion 61b, and the workpiece W2 that has reached the second placement portion 61b is released from the adsorption. As a result, it becomes a state in which the unprocessed workpiece Wl is held by the first adsorption head 53a and the processed workpiece W2 is placed on the second placement portion 61b.

[0073] Next, the control section C causes both the first and second suction heads 53a and 53b to rise. Figure 12 is a view showing a state in which the next unprocessed workpiece Wl is conveyed by the loading device 102. As shown in Figure 12 , the control section C causes both the first and second suction heads 53a and 53b to rise at the same time or almost at the same time. Note that the case where the first and second lifting rods 52a and 52b rise at the same time or almost at the same time is not limited. For example, the control section C can cause either of the first and second suction heads 53a and 53b to rise first, and cause the other to rise in or after the rising.

[0074] After that, the control section C moves the movable member 51 in the -Y direction of the front-rear direction D2, and in a state in which the unprocessed workpiece Wl is sucked by the first suction head 53a, the second suction head 53b is disposed above the carrying-in / out position P2 of the processing machine 101 (see Figure 7 ). Hereinafter, as described above, the control section C repeatedly performs the operation shown in Figures 7 to 12 . Note that in a case where the unprocessed workpiece Wl is replenished to the first placement section 61a or a case where the processed workpiece W2 placed on the second placement section 61b is recovered, the upper placement stage 61 is retracted from the entry position P3 (see Figure 2 ) to the retraction position P4 (see Figure 2 ). At this time, the unprocessed workpiece Wl is placed in advance in a portion of the lower placement stage 62 corresponding to the first placement section 61a, and the first and second placement sections 61a and 61b are used on the lower placement stage 62 as well, whereby even after the retraction of the upper placement stage 61, the same can be used in the lower placement stage 62 as well. Alternatively, the upper and lower placement stages 61 and 62 can be alternately used.

[0075] In this way, by causing the loading device 102 to operate, the suction of the unprocessed workpiece Wl on the first placement section 61a based on the first suction head 53a and the placement of the processed workpiece W2 on the second placement section 61b based on the second suction head 53b can be performed at the same time or almost at the same time without moving the movable member 51 in the front-rear direction D2, and the conveyance efficiency of the workpieces Wl and W2 can be improved, and the processing efficiency of a plurality of workpieces Wl can be improved.

[0076] In the above embodiment, the case where the first adsorption head 53a and the second adsorption head 53b are used has been described as an example, but the present application is not limited to this. For example, a case where one adsorption head 53 is used can be employed. In this case, the transport of the unprocessed workpiece Wl and the transport of the processed workpiece W2 are repeatedly performed by the one adsorption head 53. Further, in the above embodiment, only the upper stage 61 of the stages 103 is used, but a case where only the lower stage 62 is used can be employed, or a case where both the upper stage 61 and the lower stage 62 are used can be employed. In the case where both the upper stage 61 and the lower stage 62 are used, for example, a case where the unprocessed workpiece Wl is placed on either one of the upper stage 61 and the lower stage 62 and the processed workpiece W2 is placed on the other one can be employed.

[0077] In the above embodiment, the case where the workpieces Wl, W2 that are longer in the left-right direction Dl and shorter in the front-rear direction D2 are transported has been described, but in the case where workpieces (sheets) Wl l, W12 that are longer in the front-rear direction D2 are transported, the operation of the loading device 102 is different. Figures 13 to 17 Another example of the operation of the loading device 102 will be described. The workpieces Wl l, W12 represent sheets that are longer in both the left-right direction Dl and the front-rear direction D2. Further, in the above embodiment, the case where the unprocessed workpiece Wl l is placed on the upper stage 61 and the processed workpiece W12 is placed on the lower stage 62 has been described, but the case where the unprocessed workpiece Wl l is placed on the lower stage 62 and the processed workpiece W12 is placed on the upper stage 61 can be employed. Figures 13 to 17 In the operation of the loading device 102 shown in the drawing, the case where the unprocessed workpiece Wl l is placed on the upper stage 61 and the processed workpiece W12 is placed on the lower stage 62 has been described, but the same can be described even in the case where the unprocessed workpiece Wl l is placed on the lower stage 62 and the processed workpiece W12 is placed on the upper stage 61.

[0078] Figure 13 is a view showing a state where the unprocessed workpiece Wl l is transported from the upper stage 61 by the loading device 102 and placed on the processing machine 101. First, the control section C causes the movable member 51 to be arranged at a prescribed position in the front-rear direction D2 so that the first adsorption head 53a and the second adsorption head 53b are positioned above the unprocessed workpiece Wl l stacked on the upper stage 61. Thereafter, the control section C causes the first adsorption head 53a and the second adsorption head 53b to be lowered simultaneously or almost simultaneously until the upper surfaces of the workpieces Wl l of the uppermost workpiece Wl l in the unprocessed workpiece Wl l are reached. Alternatively, the control section C can cause the first adsorption head 53a and the second adsorption head 53b to be lowered at different timings.

[0079] Next, the control section C causes the first and second adsorption heads 53a and 53b to ascend after adsorbing the unprocessed workpiece W11, and moves the movable member 51 in the -Y direction of the front-rear direction D2 to position the workpiece W11 above the carrying-in and carrying-out position P2 of the processing machine 101. Thereafter, as shown in Fig. 17, the control section C causes the first and second adsorption heads 53a and 53b to descend, and places the workpiece W11 at the carrying-in and carrying-out position P2, and releases the adsorption. By this operation, the unprocessed workpiece W11 is carried into the processing machine 101. Figure 13

[0080] Next, the control section C causes the first and second adsorption heads 53a and 53b to ascend. In addition, the end portion of the workpiece W11 placed at the carrying-in and carrying-out position P2 on the +Y side is held by the workpiece holder 35, and is moved to the left and right direction D1 and the front-rear direction D2 by the conveying device 30, and is subjected to press processing at the processing position PI. During the press processing of the workpiece W11, the first and second adsorption heads 53a and 53b are on standby above the carrying-in and carrying-out position P2. Further, the processed workpiece W12 is positioned at the carrying-in and carrying-out position P2. Figure 6

[0081] Next, the control section C causes the first and second adsorption heads 53a and 53b to descend, and adsorbs the processed workpiece W12. At this time, the workpiece holder 35 releases the holding of the workpiece W12 and retreats to the +Y side. Figure 14 is a view showing a state in which the processed workpiece W12 is conveyed by the loading device 102. As shown in Fig. 18, the control section C causes the first and second adsorption heads 53a and 53b to ascend after adsorbing the processed workpiece W12, and moves the movable member 51 in the +Y direction of the front-rear direction D2 to position above the placement table 103 (the upper placement table 61). Figure 14

[0082] During the conveyance of the processed workpiece W12 above the placement table 103 or after the conveyance above the placement table 103, the upper placement table 61 is caused to retreat from the entry position P3 to the retreat position P4. Figure 15 is a view showing a state in which the upper placement table 61 is caused to retreat to the retreat position P4. As shown in Fig. 19, the upper placement table 61 is moved in the +X direction of the left and right direction D1 along the rail 63, and is positioned at the retreat position P4. In addition, the movement of the upper placement table 61 can be controlled by the control section C, or can be performed by the operation of the operator. The lower placement table 62 is positioned directly at the entry position P3, and by the movement of the upper placement table 61 to the retreat position P4, the space on the upper side of the lower placement table 62 is opened. Figure 15 ​​​​

[0083] Next, the control section C lowers the first and second adsorption heads 53a and 53b. Figure 16 is a view showing a state in which the processed workpiece W12 is placed on the lower placement table 62 by the loading device 102. As shown in the view, the control section C lowers the first and second adsorption heads 53a and 53b, and lowers the adsorbed processed workpiece W12 onto the lower placement table 62. Thereafter, the control section C places the processed workpiece W12 on the lower placement table 62 by releasing the adsorption of the first and second adsorption heads 53a and 53b. Figure 16 is a view showing a state in which the processed workpiece W12 is placed on the lower placement table 62 by the loading device 102. As shown in the view, the control section C lowers the first and second adsorption heads 53a and 53b, and lowers the adsorbed processed workpiece W12 onto the lower placement table 62. Thereafter, the control section C places the processed workpiece W12 on the lower placement table 62 by releasing the adsorption of the first and second adsorption heads 53a and 53b.

[0084] Next, the control section C raises the first and second adsorption heads 53a and 53b. Figure 17 is a view showing a state in which the adsorption heads 53 are raised. As shown in the view, after the control section C raises the first and second adsorption heads 53a and 53b, the upper placement table 61 enters the entry position P3 from the retreat position P4 in the -X direction of the left-right direction D1 along the rail 63. The entry of the upper placement table 61 into the entry position P3 can be controlled by the control section C, or can be performed by the operation of the operator. Figure 17 Thereafter, the control section C lowers the first and second adsorption heads 53a and 53b to adsorb the unprocessed workpiece W11 on the upper placement table 61. Hereafter, the control section C repeatedly performs the operations described above. In addition, in the case of repeatedly performing the operations described above, for example, the unprocessed workpiece W11 can be replenished when the upper placement table 61 is located at the retreat position P4, or the processed workpiece W12 can be recovered when the lower placement table 62 is located at the retreat position P4. In addition, it can also be configured in such a manner that the lower placement table 62 is located at the retreat position P4 when the unprocessed workpiece W11 is carried into the processing machine 101, and the lower placement table 62 is located at the entry position P3 when the processed workpiece W12 is carried out of the processing machine 101.

[0085] Figures 13 to 17

[0086] Thus, when the workpieces W11 and W12 are transported by the loading device 102, the unprocessed workpiece W11 is placed on either one of the upper and lower placement tables 61 and 62 (the upper placement table 61), and the processed workpiece W12 is placed on the other one (the lower placement table 62), and therefore, one or both of the replenishment of the unprocessed workpiece W11 and the recovery of the processed workpiece W12 can be efficiently performed.
