[0030] The travel carriage 11 is movable and has a plate shape along the horizontal direction. Figure 4 ) is U-shaped. However, the traveling cart 11 is not limited to such a shape, for example, it can also be H-shaped when viewed from above. The traveling cart 11 is equipped with a plurality of (4 in the present embodiment) traveling wheels 21, 22. However, the number of the traveling wheels 21, 22 is not limited to 4, as long as it is 3 or more, for example, the traveling wheel 2 can also be set to 1. A pair of traveling wheels 21 is arranged on both sides of the Y direction on one side of the X direction in the traveling cart 11. A pair of traveling wheels 21 is rotatably supported on the traveling cart 11 by an axle 23 along the Y direction. In addition, a pair of traveling wheels 22 is arranged on both sides of the Y direction on the other side of the X direction in the traveling cart 11. A pair of traveling wheels 22 is rotatably supported on the traveling cart 11 by an axle 24 along the Y direction.

[0031] The four running wheels 21 and 22 can be driven to rotate and can be steered. The axle 23 of the pair of running wheels 21 is supported on the running vehicle 11 via the driving steering device 25. The pair of running wheels 21 can be driven to rotate and can be steered by the driving steering device 25.

[0032] The travel vehicle 11 can be driven by, for example, an operator sitting in a driver's seat (not shown) and operating a steering wheel and an accelerator pedal or a brake pedal, or the operator can be driven by remote control without sitting in the vehicle.

[0033] The sandblasting head 12 is mounted on the traveling carriage 11. That is, the sandblasting head 12 is supported by the moving device 14, the moving device 14 is supported by the lifting device 13, and the lifting device 13 is supported by the traveling carriage 11. The lifting device 13 can move the sandblasting head 12 in the vertical direction (Z direction). The moving device 14 can move the sandblasting head 12 in the horizontal direction (Y direction).

[0034] In detail, the traveling carriage 11 is provided with a pair of supporting members 31 and 32 at intervals in the Y direction on one side in the X direction and on both sides in the Y direction. The supporting members 31 and 32 are of the same shape and are prism-shaped and longer in the Z direction. A pair of supporting arms 33 and 34 are arranged along the X direction and are arranged at intervals in the Y direction. One end of the longitudinal direction (X direction) of one supporting arm 33 is supported by the supporting member 31 so as to be movably supported in the vertical direction. One end of the longitudinal direction (X direction) of the other supporting arm 34 is supported by the supporting member 32 so as to be movably supported in the vertical direction.

[0035] That is, the support members 31 and 32 are provided with guide grooves 31a and 32a along the Z direction on the surfaces facing each other. The support arms 33 and 34 are provided with guide members 33a and 34a on the surfaces not facing each other, and the guide members 33a and 34a are respectively supported movably in the guide grooves 31a and 32a of the support members 31 and 32. The lifting device 13 includes a first drive device 35 and a second drive device 36 for moving the support arms 33 and 34 along the guide grooves 31a and 32a of the support members 31 and 32 via the guide members 33a and 34a. The first drive device 35 and the second drive device 36 are, for example, drive motors provided on one of the support members 31 and 32 and the support arms 33 and 34, and a pinion rotated by the drive motor is meshed with a rack provided on the other of the support members 31 and 32 and the support arms 33 and 34. Therefore, the first drive device 35 and the second drive device 36 can move the support arms 33 and 34 upward and downward relative to the support members 31 and 32 .

[0036] In this embodiment, the first lifting device is composed of the guide groove 31a, the guide member 33a and the first drive device 35, and the second lifting device is composed of the guide groove 32a, the guide member 34a and the second drive device 36. In addition, the first drive device 35 and the second drive device 36 are not limited to the above-mentioned structure, and may be, for example, a ball screw mechanism or a fluid cylinder mechanism.

[0037] The pair of support arms 33 and 34 are parallel to each other and are arranged at intervals in the Y direction. The pair of support arms 33 and 34 are connected to a support frame 41 at the other end in the longitudinal direction (X direction). The support frame 41 is arranged along the horizontal direction (Y direction) orthogonal to the support arms 33 and 34, and each end in the longitudinal direction (Y direction) is connected to the other end of the support arms 33 and 34. The sandblasting head 12 is supported on the support frame 41 so as to be movable along the horizontal direction (Y direction). Therefore, the lifting device 13 drives the first drive device 35 and the second drive device 36 to move the pair of support arms 33 and 34 in the vertical direction (Z direction), thereby enabling the sandblasting head 12 to move along the vertical direction (Z direction).

[0038] The sandblasting head 12 is movably supported on the support frame 41 via the swing device 42. The swing device 42 can swing the sandblasting head 12 in the vertical direction (Z direction) and the horizontal direction (Y direction). In addition, the moving device 14 can move the sandblasting head 12 in the horizontal direction (Y direction) relative to the support frame together with the swing device 42. That is, the support frame 41 is Figure 4 A guide groove 41a is provided along the Y direction on the surface side (upper side) of the support frame 41. The movable body 43 is movably supported in the guide groove 41a of the support frame 41. The moving device 14 has a driving device 44 that moves the movable body 43 along the guide groove 41a of the support frame 41. The driving device 44 is, for example, a driving motor provided on one of the support frame 41 and the movable body 43, and a pinion rotated by the driving motor is meshed with a rack provided on the other of the support frame 41 and the movable body 43. Therefore, the driving device 44 can move the movable body 43 horizontally relative to the support frame 41.

[0039] In this embodiment, the guide groove 41a, the movable body 43, and the driving device 44 constitute the moving device 14. The driving device 44 is not limited to the above-mentioned structure, and may be, for example, a ball screw mechanism or a fluid cylinder mechanism.

[0040] The swing device 42 is provided on the moving body 43, and can swing the sandblasting head 12 in the vertical direction (Z direction) and the horizontal direction (Y direction). Figure 4 and Figure 6As shown, the moving body 43 supports the first rotating shaft 45 so as to be rotatable along the X direction. The first rotating shaft 45 can rotate around the first axis O1 parallel to the X direction. The moving body 43 is provided with a first driving device 46, and the first driving device 46 can rotate the first rotating shaft 45. The first rotating shaft 45 is connected to a U-shaped connecting bracket 47 at the front end. The connecting bracket 47 is connected along a direction orthogonal to the X direction (in Figure 4 The second rotating shaft 48 is rotatably supported in the Y direction (in the X direction). The second rotating shaft 48 can rotate around a second axis O2 parallel to a direction orthogonal to the X direction. The connecting bracket 47 is provided with a second driving device 49, and the second driving device 49 can rotate the second rotating shaft 48.

[0041] The sandblasting head 12 is mounted on the second rotating shaft 48. The sandblasting head 12 is mounted on the second rotating shaft 48 in a direction orthogonal to the second rotating shaft 48. Therefore, when the first rotating shaft 45 is rotated by the first driving device 46, the sandblasting head 12 can swing around the first axis O1. In addition, when the second rotating shaft 48 is rotated by the second driving device 49, the sandblasting head 12 can swing around the second axis O2.

[0042] In addition, in this embodiment, the swing device 42 is configured as a so-called gimbal mechanism, but the present invention is not limited to this structure. For example, the swing device 42 may be configured by a spherical bearing or the like.

[0043] The paint removal device 10 includes a measuring device 51 and a camera (photographing device) 52. The support frame 41 is provided with a bracket 53 at the other end, and the measuring device 51 and the camera 52 are arranged on the bracket 53. The measuring device 51 measures the distance between the sandblasting head 12 and the outer surface of the aircraft 100. The measuring device 51 outputs the measurement result to the control unit (not shown in the figure). The control unit drives and controls the traveling trolley 11, the lifting device 13, the moving device 14 and the swing device 42 based on the measurement result of the measuring device 51 so that the distance between the sandblasting head 12 and the outer surface of the aircraft 100 is maintained at a predetermined distance. The camera 52 photographs the outer surface of the aircraft 100 from which the paint has been removed. The camera 52 outputs the photographing result to the control unit. The control unit can store the photographed image of the camera 52 in the storage unit (not shown in the figure) and display it on the display unit (not shown in the figure). The operator can confirm the paint removal state of the outer surface of the aircraft 100 by observing the photographed image of the camera 52 on the display unit.

[0044] <Sandblasting device>

[0045] Figure 7 This is a schematic diagram showing the structure of a sandblasting device.

[0046] like Figure 7As shown, the sandblasting device 60 includes a sandblasting head 12, a compressed air supply device (supply device) 61, a sandblasting pot 62, an exhaust device (recovery device) 63, an exhaust filter 64, and a separation device 65. Here, the sandblasting head 12, the sandblasting pot 62, the exhaust filter 64, and the separation device 65 constituting the sandblasting device 60 are preferably installed on the support frame 41.

[0047] The sandblasting head 12 includes a head body 12a, a cylindrical brush 12b, and a branch portion 12c. The head body 12a of the sandblasting head 12 is connected to a sandblasting pot 62, and the sandblasting pot 62 is connected to a compressed air supply device 61. Therefore, when the compressed air supply device 61 supplies compressed air, the sandblasting material B in the sandblasting pot 62 is supplied to the head body 12a, and the sandblasting material B is sprayed from the cylindrical brush 12b, for example, toward the upper surface 102a of the main wing 102 of the aircraft 100. The sandblasting material B collides with the upper surface 102a of the main wing 102, and the paint on the upper surface 102a is removed by grinding.

[0048] The branch portion 12c of the blasting head 12 is connected to the separation device 65, the separation device 65 is connected to the exhaust filter 64 and the blasting pot 62, and the exhaust filter 64 is connected to the exhaust device 63. When the exhaust device 63 acts on the suction force, the suction force acts on the blasting head 12 via the exhaust filter 64 and the separation device 65. Then, the blasting head 12 recovers the blasting material B that has collided with the upper surface 102a of the main wing 102 and the coating material P removed from the main wing 102 from the cylindrical brush 12b, and conveys them to the separation device 65 from the branch portion 12c. The separation device 65 is, for example, a cyclone separator, and separates the blasting material B from the coating material P, and returns the blasting material B to the blasting pot 62. On the other hand, the exhaust filter 64 recovers the coating material P.

[0049] The fuselage of the aircraft 100 is made of, for example, duralumin, which is an aluminum alloy. The coating on the surface of the fuselage of the aircraft 100 is, for example, a top coat of polyurethane or fluorine paint provided on the surface of a base layer of epoxy paint.

[0050] As the blasting material B, for example, alumina particles, iron particles, dry ice, etc. are used.

[0051] <Aircraft paint removal method>

[0052] Figure 8 This is a top view showing the operation of the aircraft paint removal device.

[0053] The aircraft paint removal method of this embodiment has the following steps: moving the traveling trolley 11 to make the sandblasting head 12 approach the fuselage 101 of the aircraft 100, and spraying sandblasting material toward the upper surfaces 102a, 103a of the main wing 102 and the horizontal tail 103 which are the horizontal wings of the aircraft 100; alternatingly performing the action of making the sandblasting head 12 approach the fuselage 101 of the aircraft 100 and the action of moving the sandblasting head 12 along the horizontal direction (X direction); and moving the sandblasting head 12 along the vertical direction according to the height of the upper surfaces 102a, 103a of the main wing 102 or the horizontal tail 103.

[0054] Next, the operation of continuously removing the paint from the upper surface 102a of one main wing 102 of the aircraft 100 to the fuselage 101 by the paint removal device 10 will be described. Figure 3 As shown, in the paint removal device 10, the sandblasting head 12 is placed in an upward position by using the lifting device 13, and the traveling carriage 11 is moved to stop the sandblasting head 12 at the paint removal starting position. The paint removal starting position refers to the position where the sandblasting head 12 is located above the upper surface 102a of the front end of the main wing 102.

[0055] At the paint removal start position, the sandblasting head 12 is lowered by the lifting device 13, and the position of the sandblasting head 12 is adjusted to a position facing the upper surface 102a of the rear end portion of the main wing 102 by the moving device 14. At this time, the sandblasting head 12 is in a position where the front end is in contact with the upper surface 102a of the main wing 102. That is, the sandblasting head 12 is in a state where the front end of the cylindrical brush 12b provided on the head body 12a is in contact with the upper surface 102a of the main wing 102.

[0056] In this state, if Figure 8 As shown, the sandblasting material B is ejected from the sandblasting head 12. Then, first, the sandblasting head 12 is moved from the rear end portion toward the front end portion of the main wing 102 by the moving device 14, thereby removing the paint at the front end portion of the upper surface 102a of the main wing 102. At this time, the sandblasting device 60 recovers the sandblasting material B and the painted material P. Next, the sandblasting head 12 is moved toward the fuselage 101 side by the traveling carriage 11, thereby removing the paint at the front end portion of the upper surface 102a of the main wing 102. Next, the sandblasting head 12 is moved from the front end portion toward the rear end portion of the main wing 102 by the moving device 14, thereby removing the paint at the portion of the upper surface 102a adjacent to the front end portion. In this way, by moving the sandblasting head 12 in a zigzag shape in the width direction relative to the upper surface 102a of the main wing 102, the paint from the front end portion to the base end portion of the upper surface 102a is removed.

[0057] When the blasting head 12 is moved relative to the upper surface 102 a of the main wing 102 , the control unit controls the first drive device 35 and the second drive device 36 based on the measurement result of the measuring device 51 to adjust the height of the blasting head 12 .

[0058] When the blasting head 12 and the upper surface 102 a of the main wing 102 are relatively moved, the oscillating device 42 is operated as necessary to oscillate the blasting head 12 , thereby adjusting the angle of the blasting head 12 according to the angle of the upper surface 102 a of the main wing 102 .

[0059] [Effects of this embodiment]

[0060] The first type of aircraft paint removal device comprises: a movable traveling carriage 11; a sandblasting head 12 mounted on the traveling carriage 11 and capable of spraying sandblasting materials; a lifting device 13 capable of moving the sandblasting head 12 in a vertical direction; and a moving device 14 capable of moving the sandblasting head 12 in a horizontal direction.

[0061] According to the aircraft paint removal device of the first embodiment, the sandblasting head 12 is raised and lowered by the lifting device 13 according to the height or position of the surface of the aircraft 100, and the sandblasting head 12 is horizontally moved by the moving device 14, thereby making the sandblasting head 12 face the surface of the aircraft 100. Therefore, in a state where the sandblasting head 12 faces the surface of the aircraft 100, the sandblasting material B is ejected from the sandblasting head 12 while moving, thereby making it possible to appropriately remove the paint on the surface of the aircraft 100. As a result, the operation can be simplified and the paint removal operation can be made more efficient.

[0062] The aircraft paint removal device of the second embodiment is based on the aircraft paint removal device of the first embodiment, wherein a pair of support members 31, 32 of the traveling carriage 11 are erected in the vertical direction, one end of a pair of support arms 33, 34 arranged in the horizontal direction in the longitudinal direction is supported by the pair of support members 31, 32 so as to be movably supported in the vertical direction, respectively, a support stand 41 arranged in the horizontal direction orthogonal to the support arms 33, 34 is connected to the other end of the support arms 33, 34 in the longitudinal direction, and the sandblasting head 12 is supported by the support stand 41 so as to be movably supported in the horizontal direction. Thus, by supporting the sandblasting head 12 from the support members 31, 32 of the traveling carriage 11 via the support arms 33, 34 in the horizontal direction, it is possible to prevent the traveling carriage 11 from contacting the aircraft 100 when the sandblasting head 12 is used to remove the paint from the aircraft 100.

[0063] The paint removal device for aircraft of the third embodiment is based on the paint removal device for aircraft of the second embodiment, in which the lifting device 13 can move the sandblasting head 12 in the vertical direction by moving the support arms 33 and 34 in the vertical direction, and the moving device 14 can move the sandblasting head 12 in the horizontal direction relative to the support frame 41. Thus, by moving the sandblasting head 12 in the vertical direction, the distance between the sandblasting head 12 and the surface of the aircraft 100 can be adjusted, and by moving the sandblasting head 12 in the horizontal direction, the paint removal operation can be continuously performed.

[0064] The fourth embodiment of the aircraft paint removal device is based on the aircraft paint removal device of any one of the first to third embodiments, and further includes a swing device 42 that can swing the sandblasting head 12 in the vertical direction and the horizontal direction. Thereby, the angle of the sandblasting head 12 can be appropriately adjusted relative to the angle of the surface of the aircraft 100.

[0065] The paint removal device for aircraft of the fifth embodiment is based on the paint removal device for aircraft of any one of the second to fourth embodiments, and further comprises: a compressed air supply device 61 that supplies blasting material to the blasting head 12; an exhaust device (recovery device) 63 that recovers the blasting material B and the material to be coated P ejected from the blasting head 12; and a separation device 65 that separates the recovered blasting material B from the material to be coated P. Thus, the blasting material B can be used efficiently, and the scattering of the material to be coated P can be suppressed.

[0066] The sixth embodiment of the aircraft paint removal device is based on the aircraft paint removal device of any one of the first to fifth embodiments, and the travel vehicle 11 further has at least three steerable travel wheels 21, 22. Thus, for example, the sandblasting head 12 can be moved according to the shape of the main wing 102, and the position of the sandblasting head 12 corresponding to the main wing 102 can be adjusted to an appropriate position.

[0067] The seventh embodiment of the aircraft paint removal device is based on the aircraft paint removal device of any one of the first to sixth embodiments, and is further provided with a measuring device 51 for measuring the distance between the outer surface of the aircraft 100 and the sandblasting head 12. Thus, the height or angle of the sandblasting head 12 can be adjusted according to the measurement result of the measuring device 51, and the distance between the sandblasting head 12 and the outer surface of the aircraft 100 can be appropriately maintained.

[0068] The aircraft paint removal device of the eighth embodiment is based on the aircraft paint removal device of any one of the first to seventh embodiments, and is further provided with a camera (photographing device) 52 for photographing the outer surface of the aircraft 100 from which the paint has been removed. Thus, by causing the display unit to display the outer surface of the aircraft 100 photographed by the camera 54, the operator can confirm the paint removal state of the outer surface of the aircraft 100.

[0069] The ninth embodiment of the aircraft paint removal method has the following steps: moving the traveling carriage 11 so that the sandblasting head 12 approaches the fuselage 101 of the aircraft 100, and spraying the sandblasting material toward the upper surface 102a, 103a of the main wing 102 or the horizontal tail 103 as the horizontal wing of the aircraft 100; alternately performing the action of bringing the sandblasting head 12 close to the fuselage 101 of the aircraft 100 and the action of moving the sandblasting head 12 along the horizontal direction; and moving the sandblasting head 12 along the vertical direction according to the height of the upper surface 102a, 103a of the main wing 102 or the horizontal tail 103. Thus, the paint on the upper surface 102a, 103a of the main wing 102 or the horizontal tail 103 as the horizontal wing can be appropriately removed. As a result, the operation can be simplified and the paint removal operation can be made more efficient.

[0070] The tenth embodiment of the aircraft paint removal method is based on the ninth embodiment of the aircraft paint removal method, when the sandblasting head 12 reaches the fuselage 101, the sandblasting head 12 is moved along the upper surface 101a of the fuselage 101. In this way, the paint on the upper surface 102a of the main wing 102 and the upper surface 101a of the fuselage 101 can be continuously removed.

[0071] The eleventh embodiment of the aircraft paint removal method is based on the ninth or tenth embodiment of the aircraft cleaning method, and the sandblasting head 12 is moved along the side of the vertical tail 104 of the aircraft 100. In this way, not only the paint of the main wing 102 or the fuselage 101 but also the paint of the side of the vertical tail 104 can be removed.

[0072] In the above embodiment, a double support structure is adopted in which each end of the support frame 41 is supported by a pair of support arms 33 and 34, but a cantilever support structure may be adopted in which only one end or a middle portion of the support frame is supported by a support arm.
