[Diagram 2] FIG. 2 is a perspective view showing an example of a lighting fixture to be mounted by the lighting fixture mounting device. [Diagram 3] 4 is a flowchart illustrating the operation of installing a lighting fixture by the lighting fixture mounting device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment will be described with reference to the drawings.

[0009] FIG. 1 shows a schematic side view of the lighting fixture mounting device 10, and FIG. 2 shows a perspective view of an example of a lighting fixture 11 mounted by the lighting fixture mounting device 10.

[0010] An attachment portion 13 for attaching the lighting fixture 11 is provided on the ceiling surface 12, which is the installation surface. An example of the attachment portion 13 is a pair of suspension bolts 14 protruding from the ceiling surface 12, and the lighting fixture 11 is attached to the pair of suspension bolts 14. The lighting fixture 11 is an example of a high ceiling lighting fixture that is installed in a place with a high ceiling height, but is not limited to this, and may be other lighting fixtures including, for example, base lights that can be installed on the ceiling side.

[0011] As shown in FIG. 2, the lighting fixture 11 includes a light source unit 20 having a light source, a power supply unit 21 that supplies lighting power to the light source of the light source unit 20 to light it, and an arm 22 that supports the light source unit 20 and the power supply unit 21.

[0012] An attachment portion 23 is provided on the upper surface of the arm 22 for attachment to the pair of hanging bolts 14. The attachment portion 23 is provided with a pair of attachment holes 24 through which the pair of hanging bolts 14 are inserted. The lighting fixture 11 is attached to the ceiling surface 12 by screwing a nut, via a washer, onto the tip side of the hanging bolt 14 inserted into the attachment hole 24 and tightening it.

[0013] Then, as shown in FIG. 1, the lighting fixture mounting device 10 automatically mounts the lighting fixture 11 on the pair of suspension bolts 14.

[0014] The lighting fixture mounting device 10 comprises a main body 30, a lifting section 31 that rises and falls relative to the main body 30, a position adjustment section 32 that adjusts the horizontal position of the lifting section 31 relative to the main body 30, and a fixture holding section 33, a fixture mounting section 34, an imaging section 35, an image recognition section 36, and a control section 37 provided on the lifting section 31.

[0015] The main body 30 has a plurality of wheels 40 on its underside, and these wheels 40 enable the main body 30 to travel on a floor surface 41. A battery for supplying power is disposed in the main body 30.

[0016] The main body 30 may be moved by human power, or may be self-propelled using a drive source such as a motor. When the main body 30 is self-propelled, the traveling may be controlled by a remote control or an operation unit, or the main body 30 may travel autonomously. When traveling autonomously, the main body 30 may travel while recognizing markers or the like installed on the floor, or may move to an attachment location directly below the hanging bolt 14 to which the lighting fixture 11 is attached, based on the positions of the hanging bolt 14 on the ceiling side and the installed lighting fixture 11, which are imaged by the imaging unit 35. When traveling autonomously, the main body 30 may recognize an obstacle using an image-capturing unit for traveling that captures an image in the traveling direction, or may detect an obstacle using a radar that irradiates radio waves or light in the traveling direction, in order to avoid obstacles in the traveling direction or prevent collisions.

[0017] The lifting / lowering unit 31 is installed on the position adjustment unit 32 arranged on the upper surface of the main body 30. The lifting / lowering unit 31 is raised and lowered while maintaining a horizontal posture by a lifting mechanism 44, such as an extendable pantograph structure or a slide structure. The lifting / lowering unit 31 and the lifting mechanism 44 constitute a lifting unit. Electric wires are wired between the lifting / lowering unit 31 and the main body 30 side to electrically connect them regardless of whether the lifting / lowering unit 31 is raised or lowered. The electric wires include a power supply line that supplies power from the main body 30 to the lifting / lowering unit 31 and a signal line for control between the main body 30 and the position adjustment unit 32.

[0018] Moreover, the position adjustment unit 32 moves the lifting / lowering unit 31 in the horizontal direction relative to the main body 30 to adjust the horizontal position of the lifting / lowering unit 31. The position adjustment unit 32 can adjust the position by sliding the lifting / lowering unit 31 along the X-axis and Y-axis which are orthogonal to each other in the horizontal direction. Furthermore, the position adjustment unit 32 may rotate the lifting / lowering unit 31 to adjust the orientation.

[0019] The lighting fixture 11 to be mounted is placed on the upper surface of the fixture holding part 33. The fixture holding part 33 grasps the placed lighting fixture 11 from all sides, thereby positioning and holding it at a predetermined mounting position. The position of the mounting part 23 of the lighting fixture 11 held by the fixture holding part 33, i.e., the positions of the pair of mounting holes 24, is positioned at a mounting reference position for the pair of suspension bolts 14 set in the lighting fixture mounting device 10.

[0020] The fixture mounting section 34 also has a working arm that attaches the mounting section 23 of the lighting fixture 11 to the pair of hanging bolts 14. The working arm holds a washer and a nut, and inserts the washer into the tip side of the hanging bolt 14 that has passed through the mounting hole 24 of the mounting section 23 while rotating and screwing the nut, and further tightens the nut with a predetermined tightening torque to attach the mounting section 23 to the hanging bolt 14. The fixture mounting section 34 also makes it possible to remove the nut and the washer from the hanging bolt and remove the lighting fixture 11 from the hanging bolt 14.

[0021] Moreover, the imaging unit 35 includes an imaging element, a lens that focuses light onto the imaging element, etc. The imaging unit 35 is installed on the upper surface of the lifting / lowering unit 31 at a side position of the fixture holding unit 33, with the imaging direction facing the ceiling side. The imaging unit 35 images the suspension bolt 14 when the suspension bolt 14 is located within the imaging angle, and further images the mounting area between the suspension bolt 14 and the mounting unit 23 of the lighting fixture 11 when the lifting / lowering unit 31 is raised to a mounting height (raised position) near the ceiling surface 12, making it possible to image that the suspension bolt 14 has been inserted into the mounting hole 24 of the mounting unit 23.

[0022] In addition, the image processing unit 36 ​​acquires image data captured by the imaging unit 35, and processes the acquired images to determine the positions of the pair of hanging bolts 14 on the ceiling surface 12 and the positional relationship between the pair of hanging bolts 14 and the pair of mounting holes 24 of the mounting unit 23, and sends the image processing data to the control unit 37.

[0023] The control unit 37 also controls the mounting operation of the lighting fixture 11 by the lighting fixture mounting device 10. The control unit 37 recognizes the positions of the pair of suspension bolts 14 on the ceiling surface 12 and the positional relationship between the pair of suspension bolts 14 and the mounting unit 23 of the lighting fixture 11 from image processing data captured by the imaging unit 35 and processed by the image processing unit 36, and controls the lifting and lowering of the lifting unit 31 and the operations of the position adjustment unit 32, the fixture holding unit 33, and the fixture mounting unit 34.

[0024] Next, the operation of installing the lighting fixture 11 by the control unit 37 of the lighting fixture mounting device 10 will be described with reference to the flowchart of FIG.

[0025] The lighting fixture mounting device 10 moves so that the fixture holding part 33 is positioned at the mounting location directly below the suspension bolt 14 to which the lighting fixture 11 is attached. The lighting fixture mounting device 10 may be moved manually or autonomously.

[0026] The pair of suspension bolts 14 on the ceiling surface 12 is imaged by the imaging unit 35 from above the lifting unit 31 in the lowered position, and the positions of the pair of suspension bolts 14 are recognized by image processing of the image data (step S1).

[0027] If the recognized positions of the pair of suspension bolts 14 deviate from the mounting reference positions for the pair of suspension bolts 14 set in the lighting fixture mounting device 10 (the same positions as the positions of the pair of mounting holes 24 of the mounting part 23 when the lighting fixture 11 is held by the fixture holding part 33), the position adjustment part 32 adjusts the horizontal position of the lifting part 31 so that they match (step S2). If the position is beyond the range where the position can be adjusted by the position adjustment part 32, a notification to that effect may be issued to prompt the main body 30 to be moved manually, or the main body 30 may travel autonomously to fall within the range where the position can be adjusted by the position adjustment part 32.

[0028] After the adjustment, the worker places the lighting fixture 11 on the fixture holder 33 (step S3).

[0029] The lighting fixture 11 placed on the fixture holding section 33 is positioned and held at a predetermined mounting position by gripping it from all sides. The position of the mounting section 23 of the lighting fixture 11 held by the fixture holding section 33, i.e., the positions of the pair of mounting holes 24, is positioned at a mounting reference position relative to the pair of suspension bolts 14 set in the lighting fixture mounting device 10. After holding the lighting fixture 11, the lifting section 31 rises to the mounting height relative to the suspension bolts 14 (step S4).

[0030] Even while the lifting section 31 is rising, the position of the pair of suspension bolts 14 imaged by the imaging section 35 is recognized, and if the mounting reference position for the pair of suspension bolts 14 set on the lighting fixture mounting device 10 is misaligned, the position adjustment section 32 adjusts the horizontal position of the lifting section 31 to match it (step S5).

[0031] When the lifting / lowering unit 31 is raised to the mounting height near the ceiling surface 12, an image of the mounting area between the hanging bolts 14 and the mounting portion 23 of the lighting fixture 11 is captured, and it is confirmed whether the positions of the pair of hanging bolts 14 and the mounting portion 23 of the lighting fixture 11, i.e., the pair of mounting holes 24, are correct (step S6). That is, it is confirmed whether the pair of hanging bolts 14 are inserted into the mounting holes 24 of the mounting portion 23. If the positions of the pair of hanging bolts 14 and the pair of mounting holes 24 are incorrect, that is, if the pair of hanging bolts 14 are not inserted into the pair of mounting holes 24, in step S5, the position adjustment unit 32 adjusts the horizontal position of the lifting / lowering unit 31 so that the pair of hanging bolts 14 are inserted into the pair of mounting holes 24.

[0032] Once the pair of hanging bolts 14 have been inserted into the pair of mounting holes 24, the fixture mounting unit 34 performs a mounting operation to attach the mounting unit 23 of the lighting fixture 11 to the pair of hanging bolts 14 (step S7). For example, a washer and a nut are held by the working arm of the fixture mounting unit 34, and the washer is inserted into the tip side of the hanging bolt 14 inserted into the mounting hole 24 of the mounting unit 23, and the nut is rotated and screwed to tighten. Furthermore, once the tightening torque for tightening the nut reaches or exceeds a predetermined set value (step S8), the mounting operation by the working arm of the fixture mounting unit 34 is completed.

[0033] Thereafter, the fixture holding unit 33 releases the lighting fixture 11 from its hold (step S9), and the lifting unit 31 descends to the lowered position (step S10). Since the lighting fixture 11 is attached to the suspension bolt 14, only the lifting unit 31 descends.

[0034] As described above, it is possible to provide the lighting fixture mounting device 10 capable of mounting the lighting fixture 11.

[0035] Therefore, when installing the lighting fixture 11, there is no need to assemble scaffolding or prepare a high-altitude work vehicle, and the worker does not need to move to a high place to perform the work, so the installation work of the lighting fixture 11 is not time-consuming and the time required for the installation work can be reduced.

[0036] Furthermore, if the main body 30 is self-propelled on the floor surface, it can be self-propelled to the mounting location directly below the hanging bolt 14, improving workability.

[0037] The lighting fixture mounting device 10 also enables removal of the lighting fixture 11. The lighting fixture 11 to be removed is identified based on the image captured by the imaging unit 35, and the positions of the suspension bolts 14 and nuts are identified, allowing the lighting fixture 11 to be removed from the suspension bolts 14 and lowered by performing the reverse operation to that performed during the installation described above.

[0038] The mounting portion 13 installed on the ceiling surface 12 is not limited to the pair of hanging bolts 14, and may be, for example, a hook-on ceiling body. In the case of a hook-on ceiling body, by rotatably providing an attachment unit including a pair of connecting blades that can be attached to the hook-on ceiling body on the attachment portion 23 of the lighting fixture 11, it becomes possible to rotate the attachment unit by the fixture attachment portion 34 and attach it to the hook-on ceiling body when installing the lighting fixture 11.

[0039] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
