Description
[Technical field]
[0001] The present disclosure relates to a fire detector inspection device used for inspecting a fire detector. [Background technology]
[0002] Conventionally, automatic fire alarm systems have been used that detect the occurrence of a fire using fire detectors and issue an alarm. Fire detectors detect the occurrence of a fire by heat and smoke. In buildings such as apartment buildings and public facilities, automatic fire alarm systems that receive the detection results from the fire detectors to a receiver and issue an alarm from the alarm are installed, and regular inspection of each device is mandatory. Fire detector inspections are performed by actually generating heat and smoke using a test device that is placed close to the fire detector. For example, Patent Document 1 discloses an inspection device that inspects fire detectors installed on the ceiling by attaching a smoke-applying test device to the tip of a support rod.

[0023] Hereinafter, an embodiment of a fire detector inspection device according to the present disclosure will be described with reference to the accompanying drawings. The type of fire detector to be inspected by the fire detector inspection device is not particularly limited, but the inspection targets include fire detectors that detect smoke and fire detectors that detect heat. Since the method of inspecting fire detectors is conventionally known, detailed explanations will be omitted. However, the inspection of a smoke-detecting fire detector is performed by covering the fire detector with a smoke tester and generating smoke inside. The inspection of a heat-detecting fire detector is performed by covering the fire detector with a heating tester and heating the inside. Hereinafter, the inspection equipment that generates smoke, heat, etc. will be referred to as a "tester" to distinguish it from the fire detector inspection device.
[0024] [Embodiment 1] 1 is a diagram for explaining an overview of a fire detector inspection device 1 according to embodiment 1. The fire detector inspection device 1 includes a main body 10, a tape body 100 that is fed out and stored from the main body 10, and a tester 200 that is detachably fixed to a base 110 at the tip of the tape body 100.
[0025] Fig. 1 shows three-dimensional coordinate axes that are orthogonal to each other. Some of the other figures also show coordinate axes to show the relationship between the components shown in each figure. The XY plane shows the horizontal plane, and the Z axis shows the up-down direction. The Y axis shows the width direction of the tape body 100.
[0026] The fire detector inspection device 1 can move the tester 200 vertically by unwinding and rewinding the tape body 100 using a tape measure mechanism. Unwinding the tape body 100 outside the device and storing the tape body 100 inside the device causes the tester 200 to move linearly back and forth vertically. The tape body 100 is unwound upward from the main body 10 of the fire detector inspection device 1, and the tester 200 is raised to the installation position of the fire detector 2, thereby inspecting the fire detector 2. Hereinafter, the fire detector inspection device will be referred to as the "inspection device" and the fire detector will be referred to as the "detector" for the remainder of the explanation.
[0027] As shown in Fig. 1, a plurality of wheels 20 are attached to the bottom surface of the main body 10 of the inspection device 1, so that the inspection device 1 can be moved along the floor surface. The wheels 20 are provided with a locking mechanism (not shown), and when the wheels 20 are locked by the locking mechanism, the position of the main body 10 on the floor surface is fixed. However, the main body 10 is not limited to having the wheels 20, and the main body 10 without the wheels 20 may be lifted up and transported, or may be moved on a dolly or the like.
[0028] The main body 10 is provided with an operation unit 31. A user of the inspection device 1 can operate the operation unit 31 to raise the tester 200 by unwinding the tape body 100 upward from the main body 10. A user can operate the operation unit 31 to lower the tester 200 by winding and storing the tape body 100 inside the main body 10. The operation unit 31 may be a mechanical operator such as a push button, or may be a touch panel type liquid crystal operator.
[0029] The main body 10 may be provided with a display unit 32 that displays information regarding the use of the inspection device 1. For example, before starting an inspection operation, information instructing the unwinding and retracting directions of the tape body 100 to be vertical is displayed on the display unit 32. A liquid crystal display device may be provided on the upper surface of the main body 10 and used as the display unit 32, or a touch panel type liquid crystal display device may be used as the operation unit 31 and the display unit 32.
[0030] The main body 10 may be provided with a notification unit 33 that notifies information regarding the use of the inspection device 1. For example, when a user operates the operation unit 31 to raise the tester 200, if the unwinding direction and storage direction of the tape body 100 deviate from the vertical direction, the notification unit 33 notifies the user of this. The notification may be performed by emitting a sound or by changing the light emission state. The angles between the unwinding direction and storage direction of the tape body 100 and the vertical direction may be detected using a conventionally known sensor. Instead of or in addition to the notification by the notification unit 33, the notification may be performed by displaying predetermined information on the display unit 32.
[0031] The tape body 100 is composed of a plurality of long plates 100a, 100b (see FIG. 6(a)). Each of the long plates 100a, 100b has a curved cross-sectional shape in which a thin band-shaped metal plate is curved in an arc shape in the width direction (Y-axis direction). For example, the long plates 100a, 100b are made of stainless steel such as SUS304 having a thickness of 0.3 mm and a width of about 50 mm, and curved to a width of about 30 to 35 mm. The two long plates 100a, 100b are arranged in a positional relationship in which the convex surfaces face each other at the approximate center in the width direction of the curved shape, and are used as the tape body 100. However, as long as the tape body 100 can be unwound and stored as described in this embodiment, the material, dimensions, and shape of the tape body 100 are not particularly limited.
[0032] A base 110 for mounting a tester 200 is fixed to the tip of the tape body 100. The tester 200 is detachably fixed to the base 110 to inspect the detector 2.
[0033] 2 is a diagram for explaining how to use the tester 200. As shown in FIG. 2(a), a plurality of types of testers 200, such as a smoke-type tester 200 and a heat-type tester 200, can be attached to the base 110. Depending on the type of detector 2 and the purpose of inspection, the tester 200 on the base 110 is changed to inspect the detector 2. As shown in FIG. 1, even after the tester 200 is fixed to the base 110, the main body 220 of the tester 200 can rotate around the axis 201.
[0034] 2(a), a detachable part 240 is provided on the bottom surface of a support part 230 that rotatably supports the main body part 220, and the detachable part 240 is detachably fixed to the base part 110. As long as the support part 230 can be fixed to the base part 110, the method of detachment is not particularly limited. Attachment and detachment may be performed by a conventionally known method such as a screw type, a snap fit type, a magnet type, a ratchet type, or a fitting type.
[0035] The tester 200 is supported by the support 230 with its upper surface horizontal. As shown in FIG. 2(b), when the detector 2 is installed at an angle, when the tape body 100 is paid out from the main body 10 of the inspection device 1 to raise the detector 200, only a part of the upper surface of the main body 220 first comes into contact with the ceiling surface. When the tester 200 is further raised, the main body 220 starts to rotate around the axis 201 and tilt. As a result, as shown in FIG. 2(c), the detector 2 can be inspected by bringing almost the entire upper surface of the main body 220 of the tester 200 into contact with the tilted ceiling surface and placing the detector 2 inside the main body 220.
[0036] Aiming device 210 (210a, 210b) is provided on the upper part of main body 220 of tester 200. As shown by the dashed line in Fig. 1, aiming device 210 projects marks 250 (250a, 250b) on the ceiling surface so that a position corresponding to the central axis of main body 220 having a cylindrical shape can be identified.
[0037] FIG. 3 is a diagram for explaining an example of the aiming device 210. The aiming device 210 includes a plurality of laser devices 210a, 210b. The laser devices 210a, 210b are line marker type irradiation devices that irradiate linear laser light. Each of the laser devices 210a, 210b is fixed to the main body 220 by adjusting the position so that the linear line marks 250a, 250b projected on the ceiling surface pass through the central axis of the main body 220 of the tester 200. The intersection of the multiple line marks 250a, 250b projected on the ceiling surface from each of the laser devices 210a, 210b specifies the position corresponding to the tester 200, i.e., the position corresponding to the central axis of the main body 220 of the tester 200.
[0038] In the example shown in FIG. 3, two laser devices 210a and 210b are fixed to the main body 220 so that one of them projects a line mark 250a in the Y-axis direction and the other projects a line mark 250b in the X-axis direction, and the two line marks 250a and 250b are perpendicular to each other. As shown in FIG. 1, even if the tester 200 is far below the ceiling surface, the aiming device 210 projects a mark 250 that can identify the position corresponding to the tester 200 onto the ceiling surface. The user can move the inspection device 1 while checking the mark 250 on the ceiling surface. As shown in FIG. 3, the user moves the inspection device 1 to adjust the position of the tester 200 so that the position corresponding to the central axis of the main body 220 of the tester 200 shown on the ceiling surface by the multiple line marks 250a and 250b overlaps with the center position of the sensor 2, and then operates the operation unit 31 to raise the tester 200 and inspect the sensor 2.
[0039] 4 is a block diagram showing an example of a functional configuration of the inspection device 1. The inspection device 1 includes a storage unit 40, a control unit 50, a driving unit 60, and an inclination sensor 70 in addition to the components shown in FIGS.
[0040] The memory unit 40 is a non-volatile storage device that stores programs and data necessary for the operation of the inspection device 1. The drive unit 60 is an actuator such as a motor that drives the tape measure mechanism to pay out and store the tape body 100. The tilt sensor 70 is a sensor that can detect the tilt direction and tilt angle, and is fixed to the inspection device 1 for use in detecting whether the payout direction and storage direction of the tape body 100 coincide with the vertical direction.
[0041] The control unit 50 controls each unit constituting the inspection device 1. The control unit 50 includes a vertical detection unit 50a, a notification control unit 50b, and a payout / storage control unit 50c. For example, programs corresponding to these are pre-stored in the storage unit 40, and the functions and operations of the control unit 50 are realized by hardware such as a CPU executing the programs.
[0042] The vertical detection unit 50a judges whether the payout direction and storage direction of the tape body 100 are vertical or not based on the detection result by the inclination sensor 70. The notification control unit 50b executes notification processing based on the judgment result of the vertical detection unit 50a. For example, when the payout direction and storage direction of the tape body 100 deviate from the vertical direction beyond a predetermined error range, notification processing for notifying the user of this is executed using the display unit 32 and / or the notification unit 33. When the payout direction and storage direction of the tape body 100 deviate from the vertical direction beyond a predetermined threshold, the user is notified by sound, light, information display, etc.
[0043] The payout / storage control section 50c controls the drive section 60 based on the operation performed by the operation section 31 to pay out the tape body 100 from the main body section 10 and store the tape body 100 in the main body section 10.
[0044] Fig. 5 is a diagram for explaining an example of the internal configuration of the inspection device 1. Fig. 5(a) is a schematic diagram showing an example of the configuration of the inspection device 1. Fig. 5(b) is a diagram showing an example of the external appearance of the inspection device 1. The components shown in Fig. 5(a) are housed inside the main body 10 as shown in Fig. 5(b). In Fig. 5(b), some of the components 300, 301 shown in Fig. 5(a) are indicated by dashed lines.
[0045] As shown in FIG. 5(a), a tape measure unit 300 including a tape measure mechanism for unwinding and storing the tape body 100 is provided with an inclination sensor 70 and a drive unit 60 (60a, 60b) for unwinding and storing the tape body 100. The tape measure unit 300 is fixed to a table 90 via moving mechanisms 81, 82 for moving the position of the tape measure unit 300. The tape measure unit 300 is fixed so that the unwinding and storing directions of the tape body 100 are vertical when the table 90 is in a horizontal state. The inclination sensor 70 detects deviations of the unwinding and storing directions of the tape body 100 from the vertical direction, i.e., deviations of the table 90 from the horizontal state. The location where the inclination sensor 70 is provided is not particularly limited, and the inclination sensor 70 may be provided on the table 90.
[0046] Height adjustment screws 91-93 for changing the position of the table 90 in the height direction at each location are spaced apart from one another at multiple locations on the table 90. The number of adjustment screws is not particularly limited, but in the example shown in Fig. 5(a), height adjustment screws 91-93 are provided at three ends corresponding to the vertices of the table 90 having a substantially triangular flat plate shape. The horizontal mechanism including the table 90 and the height adjustment screws 91-93 can change the horizontal state of the table 90, i.e., the inclination of the tape measure unit 300 fixed to the table 90 with respect to the horizontal plane.
[0047] When the height adjustment screws 91-93 are tightened, the table 90 rises, and when the height adjustment screws 91-93 are loosened, the table 90 falls. Dials 191-193 are fixed to the height adjustment screws 91-93. As shown in FIG. 5(b), the dials 191-193 are arranged so that at least a portion thereof is exposed to the outside of the main body 10. A user can perform a leveling operation by rotating the dials 191-193 forward or backward to change the inclination of the table 90 and make it horizontal. When the table 90 is horizontal after leveling, the payout direction and storage direction of the tape body 100 become vertical.
[0048] The table 90 is provided with a moving mechanism 81 that moves the tape measure unit 300 in a first horizontal axis direction on the leveled table 90, and a moving mechanism 82 that moves the tape measure unit 300 in a second horizontal axis direction perpendicular to the first horizontal axis. The moving mechanisms 81 and 82 are ball screw type moving mechanisms including a screw shaft and moving tables 281 and 282 that move in the axial direction of the screw shaft as the screw shaft rotates. The moving mechanism 82 is fixed to the moving table 281 of the moving mechanism 81, and the tape measure unit 300 is fixed to the moving table 282 of the moving mechanism 82. When the screw shaft of the moving mechanism 81 is rotated forward, the moving table 281 and the moving mechanism 82 fixed to the moving table 281 move forward along the screw shaft, and when the screw shaft is rotated backward, the moving table 281 moves backward along the screw shaft. When the screw shaft of the moving mechanism 82 is rotated in the forward direction, the moving table 282 and the tape measure unit 300 fixed to the moving table 282 move in the forward direction along the screw shaft, and when the screw shaft is rotated in the reverse direction, the tape measure unit 300 moves in the reverse direction along the screw shaft.
[0049] In the example shown in Figure 5(a), after table 90 is made horizontal, when the screw shaft of moving mechanism 81 is rotated, moving mechanism 82 and tape measure unit 300 move in the Y-axis direction, and when the screw shaft of moving mechanism 82 is rotated, tape measure unit 300 moves in the X-axis direction.
[0050] Handles 181, 182 for rotating the screw shaft are provided on one end of the screw shaft of each of the moving mechanisms 81, 82. As shown in Fig. 5(b), the handles 181, 182 are exposed to the outside of the main body 10 of the inspection device 1. The user can change the position of the tape measure unit 300 by rotating the handles 181, 182 forward and backward.
[0051] As shown by the dashed line in Fig. 5(b), the components below the tape measure unit 300 shown in Fig. 5(a) are housed inside the box-shaped main body 10 with at least a part of the dials 191-193 and the handles 181, 182 exposed from the main body 10. The lower ends of the height adjustment screws 91-93 are rotatably fixed to the inside bottom surface of the box-shaped main body 10 to restrict the horizontal movement of the table 90, while the inclination of the table 90 can be changed by rotating the dials 191-193 to perform leveling. Note that the dials 191-193 and the handles 181, 182 are omitted from Fig. 1 and other figures.
[0052] As shown in FIG. 5(b), the main body 10 has a cylindrical neck 10a formed on the upper surface. The components shown in FIG. 5(a) are fixed inside the main body 10 so that the payout opening 301 can move in the X-axis direction and the Y-axis direction inside the neck 10a. For example, the payout opening 301 can move about 20 to 30 mm in the X-axis direction and the Y-axis direction inside the neck 10a. This allows the position of the tape measure part 300 including the payout opening 301, i.e., the position of the tape body 100 paid out upward, to be changed while the position of the main body 10 is fixed on the floor surface.
[0053] Fig. 6 is a diagram showing an example of the configuration of the tape measure unit 300. Fig. 6(a) is a diagram showing an example of the internal configuration of the tape measure unit 300. Fig. 6(b) is a diagram for explaining a method of driving the tape measure unit 300 that realizes a tape measure mechanism.
[0054] The tape measure section 300 includes a reeling outlet 301 for the tape body 100. As shown in the cross-sectional view of FIG. 6(a), the reeling outlet 301 has a shape obtained by hollowing out a cylinder to match the cross-sectional shapes of the long plates 100a and 100b that are arranged facing each other so that the convex surfaces of the curved shapes are aligned. For example, the reeling outlet 301 has a shape in which a through hole with an approximately X-shaped upper surface is formed in the axial direction of a cylindrical hard resin having a cylindrical shape to match the cross-sectional shape of the tape body 100. The reeling outlet 301 can support the curved long plates 100a and 100b along their shapes by the inner side surface 301a that extends in the vertical direction (Z-axis direction) and forms the through hole. The reeling outlet 301 can regulate the reeling positions of the long plates 100a and 100b in a horizontal plane by the inner side surface 301a. When the table 90 is placed in a horizontal position, the payout opening 301 can regulate the payout and retraction directions of the long plates 100a, 100b in the vertical direction by the inner surface 301a.
[0055] As shown in Fig. 6(a), the tape measure unit 300 contains a pair of storage units 320 (320a, 320b) for storing the long plates 100a, 100b that make up the tape body 100, and a pair of rollers 310 (310a, 310b) for unwinding and storing the tape body 100. The rollers 310a and 310b have the same structure. The storage units 320a and 320b have the same structure.
[0056] The storage units 320a, 320b wind up the long plates 100a, 100b in a tape measure shape and store them. Each storage unit 320a, 320b includes a drum having one end of the long plates 100a, 100b fixed to the base unit 110 and the other end fixed to the outer circumferential surface. The storage units 320a, 320b rotate the drum to wind up the long plates 100a, 100b in a spiral shape around the outer periphery of the drum and store them. When the long plates 100a, 100b are paid out from the payout opening 301, they return to a shape curved in the width direction, and when they are taken up on the drum, they are taken up in a substantially flat shape.
[0057] As shown in Fig. 6(a), the rollers 310a, 310b are arranged facing each other with the long plates 100a, 100b sandwiched therebetween. As shown in Fig. 6(b), the rotation shafts 311a, 311b of the rollers 310a, 310b are arranged apart in the X-axis direction with their axial directions parallel to the Y-axis. The rotation shafts 311a, 311b are supported by the tape measure unit 300 so as to be rotatable with the outer circumferential surfaces of the rollers 310a, 310b pressed against the long plates 100a, 100b from both outsides. When one of the two rollers 310a, 310b is rotated, the long plates 100b, 100a move due to frictional force, and the other roller rotates accordingly.
[0058] The rotating shaft 311a of the roller 310a is connected to a rotation sensor such as a rotary encoder. The payout / storage control unit 50c can determine the payout amount of the tape body 100 based on the amount of rotation of the roller 310a detected by the rotation sensor and the outer diameter of the roller 310a. The payout / storage control unit 50c can stop the payout of the tape body 100 when the payout amount of the tape body 100 reaches a preset value. For example, the payout / storage control unit 50c can automatically stop the payout of the tape body 100 at a payout amount that requires the attachment of an auxiliary tool, which will be described later.
[0059] The rotation sensor is also used to control the storage of the tape body 100. When storing the tape body 100 that has been unwound from the storage section 320, the tape body 100 is wound onto the drum of the storage section 320, and the bottom surface of the base section 110 fixed to the upper end of the tape body 100 comes into contact with the upper surface of the pay-out opening 301, so that the tape body 100 cannot move and the rotation of the roller 310 stops. By detecting this with the rotation sensor, the pay-out / storage control section 50c can determine that storage of the tape body 100 is complete and stop storing the tape body 100. The pay-out / storage control section 50c may use the rotation sensor to detect the pay-out and take-up amounts of the tape body 100, and stop storing the tape body 100 by the drive sections 60a, 60b based on the fact that the take-up amount of the tape body 100 matches the pay-out amount.
[0060] As shown in Fig. 6(a), the driving unit 60a provided near the roller 310b rotates the rotating shaft 311b to rotate the roller 310b. When the driving unit 60a rotates the roller 310b, the long plates 100a and 100b, which are pressed against the outer circumferential surfaces of the rollers, move between the rollers 310b and 310a. As the long plate 100a moves, the roller 310a rotates in the opposite direction to the roller 310b. That is, by receiving the driving force from the driving unit 60a, the rollers 310a and 310b rotate in the opposite directions at the same rotational speed.
[0061] 6(b), when the driving unit 60a rotates the roller 310b clockwise, the roller 310a rotates counterclockwise at the same rotational speed, and the tape body 100 made up of the two long plates 100a, 100b is paid out upward from the pay-out opening 301. When the driving unit 60a rotates the roller 310b counterclockwise, the roller 310a rotates clockwise at the same rotational speed, and the tape body 100 is rewound from the pay-out opening 301 and stored in the storage unit 320.
[0062] As shown in FIG. 6(b), a pair of gears 330 (330a, 330b) are fixed to the rotating shafts 321a, 321b of the drums that wind the long plates 100a, 100b in the respective storage sections 320a, 320b. The gears 330a and 330b have the same structure. The rotating shafts 321a, 321b are arranged apart in the X-axis direction with their axial directions parallel to the Y-axis. The rotation of the gears 330a, 330b rotates the drums of the respective storage sections 320a, 320b. Note that the present invention is not limited to an embodiment in which the drum and the gear 330 are separate structures, and the gear 330 may constitute the drum. For example, a bobbin-shaped drum having a body portion between two gears 330a spaced apart in the Y-axis direction, and a bobbin-shaped drum having a body portion between two gears 330b may be used, and the long plates 100a, 100b may be wound around the body portions of each drum.
[0063] As shown in FIG. 6(a), when the driving unit 60b provided near the storage unit 320b drives and rotates the rotating shaft 321b, the drum of the storage unit 320b fixed on the shaft rotates. When the gear 330b fixed to the rotating shaft 321b rotates, the gear 330a rotates in the opposite direction at the same rotation speed as the gear 330b. With the rotation of the gear 330a, the drum of the storage unit 320a fixed to the same rotating shaft 321a also rotates. That is, by receiving the driving force from the driving unit 60b, the drum that feeds and winds the long plate 100a in the storage unit 320a and the drum that feeds and winds the long plate 100b in the storage unit 320b rotate in the opposite directions at the same rotation speed.
[0064] As shown by the arrows in Fig. 6(b), when the driving unit 60b rotates the drum of the storage unit 320b clockwise, the drum of the storage unit 320a rotates counterclockwise at the same rotational speed, and each of the long plates 100a, 100b is paid out from the storage units 320a, 320b. When the driving unit 60b rotates the drum of the storage unit 320b counterclockwise, the drum of the storage unit 320a rotates clockwise at the same rotational speed, and each of the long plates 100a, 100b is stored in the storage units 320a, 320b.
[0065] When the tape body 100 is paid out from the tape measure unit 300, the payout / storage control unit 50c controls the two drive units 60a, 60b so that the payout speed of the tape body 100 by the roller 310 is the same as the payout speed of the long plates 100a, 100b by the storage unit 320. When the tape body 100 is stored in the tape measure unit 300, the payout / storage control unit 50c controls the two drive units 60a, 60b so that the storage speed of the tape body 100 by the roller 310 is the same as the storage speed of the long plates 100a, 100b by the storage unit 320.
[0066] The tape measure unit 300 can reliably unwind and store the tape body 100 by forcibly rotating the rollers 310a, 310b and the drums of the storage units 320a, 320b in synchronism with each other. When using thick metal long plates 100a, 100b, the long plates 100a, 100b may not be wound around the drums well using only the restoring force of a spiral spring as in the conventional tape measure mechanism. The tape measure unit 300 can reliably wind the long plates 100a, 100b around the drums and store them in the storage units 320a, 320b by forcibly rotating the drums. The present invention is not limited to a mode in which the driving unit 60a for the rollers 310 and the driving unit 60b for the drums of the storage unit 320 are provided separately, and may be a mode in which one driving unit 60 rotates both the rollers 310 and the gear 330 using a gear mechanism that transmits driving force to the rollers 310 and the gear 330.
[0067] 7 is a diagram showing an example of rollers 310a, 310b used for feeding and storing the tape body 100. The rollers 310a, 310b include metallic inner peripheral parts 313a, 313b including rotating shafts 311a, 311b, and non-metallic outer peripheral parts 314a, 314b fixed to the outer peripheral surfaces of the inner peripheral parts 313a, 313b. The outer peripheral parts 314a, 314b made of a high friction material such as resin or rubber are fixed to the metallic inner peripheral parts 313a, 313b having high strength and durability. For example, by using the rollers 310a, 310b with the outer peripheral parts 314a, 314b made of urethane, slippage is prevented between the long plates 100a, 100b and the rollers 310a, 310b. By utilizing the outer peripheral portions 314a, 314b made of an elastic material, the roller 310, which is arranged opposite the long plates 100a, 100b with its outer peripheral surface pressed against them, can rotate while deforming its outer peripheral surface to conform to the long plates 100a, 100b, as shown in the upper diagram of Figure 7.
[0068] Here, an example of how a user uses the inspection device 1 will be described. First, the user attaches the tester 200 to the base 110 fixed to the tip of the tape body 100, i.e., the tips of the multiple long plates 100a, 100b, as described in Fig. 2. The user turns on the power of the aiming device 210, and projects the aiming mark 250 onto the ceiling surface on which the detector 2 is installed, as described in Fig. 3. The user moves the inspection device 1 on the floor surface so that the position of the central axis of the tester 200 indicated by the mark 250 projected onto the ceiling surface as shown in Fig. 1 coincides with the center position of the detector 2, and then locks the wheels 20 to fix the position of the inspection device 1.
[0069] As described in FIG. 5, the user operates the dials 191 to 193 to adjust the level of the table 90. For example, if the table 90 is not level, that is, if the payout direction and the storage direction of the tape body 100 are not vertical, this is detected by the inclination sensor 70 and the display unit 32 and / or the notification unit 33 notify the user by sound, light, information display, or the like. Based on this notification, the user can turn the dials 191 to 193 to adjust the level. A level may be provided on the upper surface of the main body 10 of the inspection device 1, and the user may turn the dials 191 to 193 while checking the level to adjust the level. The vertical detection unit 50a may display information indicating the inclination state of the table 90 on the display unit 32 based on the output value of the inclination sensor 70, and the user may adjust the level by referring to the display on the display unit 32.
[0070] After completing the leveling, the user checks again the positional relationship between the mark 250 projected onto the ceiling surface and the detector 2, and fine-tunes the position of the tester 200 as necessary. As explained in Fig. 5, the user can adjust the position of the tester 200 by turning the handles 181 and 182. Although the wheels 20 are locked and the position of the main body 10 is fixed, the user can fine-tune the position of the tester 200, i.e., the payout position of the tape body 100, by turning the handles 181 and 182 and moving the position of the tape measure part 300 within the main body 10.
[0071] After completing the position adjustment, the user operates the operation unit 31 to raise the tester 200. As described in Fig. 6, the payout / storage control unit 50c controls the drive unit 60 in response to the operation performed on the operation unit 31, whereby the tape body 100 is paid out from the tape measure unit 300 and the tester 200 is raised.
[0072] When the user performs an operation to raise the tester 200, the vertical detection unit 50a judges whether the payout direction and the storage direction of the tape body 100 are vertical or not by using the inclination sensor 70. If the payout direction and the storage direction of the tape body 100 deviate from the vertical direction, the vertical detection unit 50a notifies this by the notification unit 33. Even if the user forgets to perform the leveling work and the payout direction and the storage direction of the tape body 100 deviate from the vertical direction, the user notices this by receiving the notification by the notification unit 33 and can perform the leveling work. By setting the payout direction and the storage direction of the tape body 100 to the vertical direction before raising the tester 200 to a high position, it is possible to prevent the tester 200 from rising obliquely upward and the tape body 100 from buckling.
[0073] Before the payout / storage control unit 50c operates the drive unit 60 in response to a user's operation, the vertical detection unit 50a may execute a determination process, and if it determines that the payout direction and storage direction of the tape body 100 deviate from the vertical direction, the payout / storage control unit 50c may not operate the drive unit 60. Until the vertical detection unit 50a determines that the payout direction and storage direction of the tape body 100 are vertical, the drive unit 60 is not driven even if the operating unit 31 is operated, and the tester 200 is not raised, thereby reliably preventing buckling of the tape body 100.
[0074] The user raises the tester 200 and inspects the detector 2. After completing the inspection, the user again operates the operation unit 31 to lower the tester 200 and finish the inspection work.
[0075] The inspection device 1 is capable of using an auxiliary tool to prevent buckling of the tape body 100. Fig. 8 is a diagram for explaining how to use the auxiliary tool 401. Fig. 8(a) shows how to attach the auxiliary tool 401 to the inspection device 1, and Fig. 8(b) shows the auxiliary tool 401 after attachment.
[0076] As shown in FIG. 8(a), the auxiliary tool 401 is composed of two members 401a and 401b. A plurality of convex portions 404a are formed on one member 401a, and concave portions 404b having shapes corresponding to the convex portions 404a are formed on the other member 401b at positions corresponding to the convex portions 404a. The convex portions 404a and the concave portions 404b are formed on the mating surfaces when the two members 401a and 401b are assembled. As long as the two members 401a and 401b can be positioned and assembled detachably, the shapes, materials, dimensions, and numbers of the convex portions 404a and the concave portions 404b are not particularly limited. For example, a cylindrical pin may be the convex portion 404a, and a hole that fits the pin may be the concave portion 404b. The convex portions 404a and the concave portions 404b may be slid vertically to realize a dovetail-shaped fitting mode. The convex portion 404a and the concave portion 404b may be of a type that realizes a fitting manner such as a screw type, a snap fit type, a magnet type, or a ratchet type.
[0077] As shown by the arrows in Fig. 8(a), the two members 401a, 401b are positioned and fixed together by inserting each of the convex portions 404a into the corresponding concave portions 404b so as to sandwich the tape body 100, as shown in Fig. 8(a). The neck portion 10a of the main body 10 is inserted into the lower end portion 403 (403a, 403b) of the auxiliary tool 401, which has been integrated into a substantially cylindrical shape. As a result, the auxiliary tool 401 is positioned and fixed with respect to the main body 10, as shown in Fig. 8(b).
[0078] 9 is a diagram showing a configuration example of the auxiliary tool 401. As shown in FIG. 9(a), support surfaces 412 (412a, 412b) and 413 (413a, 413b) are formed on the upper end portions 402 (402a, 402b) of the two members 401a and 401b, respectively, to match the shape of the tape body 100. When the convex portion 404a of the member 401a is inserted into the concave portion 404b of the member 401b and integrated as shown in FIG. 9(b), the support surfaces 412a and 412b form inner surfaces extending in the vertical direction (Z-axis direction) to match the cross-sectional curved shape of the long plates 100a and 100b. The support surfaces 412a and 412b extending in the vertical direction support the long plates 100a and 100b from both outer sides along the cross-sectional curved shape. The support surfaces 413 (413a, 413b) extending in the up-down direction form inner surfaces that restrict the movement of the long plates 100a, 100b in the width direction (Y-axis direction) from both outsides.
[0079] The upper end 402 can support the long plates 100a, 100b curved in the width direction (Y-axis direction) inside an axial through hole having inner surfaces that function as support surfaces 412, 413. The upper end 402 can regulate the extension positions of the long plates 100a, 100b in a horizontal plane with the inner surfaces. The upper end 402 can regulate the extension and retraction directions of the long plates 100a, 100b in the vertical direction with the inner surfaces.
[0080] Note that the present invention is not limited to a configuration in which the tape body 100 is supported only by the upper end portion 402, but the auxiliary tool 401 may support the tape body 100 over substantially the entire axial direction of the auxiliary tool 401 except for the lower end portion 403 into which the neck portion 10a is inserted, as shown in the cross-sectional view of Figure 9(b).
[0081] As shown in FIG. 9(b), the upper end 402 of the auxiliary tool 401, which is integrated by assembling two members 401a and 401b, has a stepped cylindrical shape. Specifically, the upper end 402 has a stepped shape in which the outer diameter is the same as the outer diameter of the neck 10a of the main body 10 in a part of the region from the upper end in the axial direction (Z-axis direction), and the outer diameter is enlarged in at least a part of the region below the part. In other words, the upper part of the upper end 402 has a stepped shape that reproduces the shape from the upper surface of the main body 10 to the neck 10a. This allows the upper end 402, which reproduces the neck 10a, to be inserted into the lower end 403 of another auxiliary tool 401 and connected. The other auxiliary tool 401 connected from above is stopped and fixed at the stepped portion formed in the upper end 402 of the lower auxiliary tool 401.
[0082] 10 is a diagram for explaining a method of connecting auxiliary tools 401 and 411. Although different reference numerals are used to simplify the explanation, auxiliary tool 401 and auxiliary tool 411 are the same product. Hereinafter, when there is no need to distinguish between them, they will be referred to as auxiliary tool 401.
[0083] As shown in Fig. 10(a), the auxiliary tool 401 attached to the neck part 10a of the main body 10 as shown in Fig. 8(b) is slid upward as shown in Fig. 10(a). Since the auxiliary tool 401 has a tubular shape through which the tape body 100 is inserted, the auxiliary tool 401 can be slid upward as it is without being divided into two members 401a and 401b.
[0084] With the auxiliary tool 401 retracted upward, another auxiliary tool 411 is attached as shown in Fig. 10(a). The auxiliary tool 411 is fixed to the main body 10 by assembling two members 411a, 411b with the tape body 100 sandwiched therebetween, in the same manner as in assembling the auxiliary tool 401, and inserting the neck portion 10a into the lower end portion 403.
[0085] After the auxiliary tool 411 is fixed to the main body 10, the auxiliary tool 401, which has been retracted upward, is slid downward as shown in Fig. 10(b). The upper end 402 of the auxiliary tool 411 on the lower side is inserted into the lower end 403 of the auxiliary tool 401 on the upper side, whereby the auxiliary tool 401 and the auxiliary tool 411 are connected and fixed.
[0086] Fig. 11 is a schematic cross-sectional view for explaining a method for connecting auxiliary tools 401 and 411. Fig. 11(a) corresponds to Fig. 8, and Fig. 11(b) corresponds to Fig. 10. Note that Fig. 11 omits illustration of convex portion 404 and the like, and shows the configuration necessary for explaining the connecting method.
[0087] As shown in the left figure of Figure 11(a), when the neck portion 10a of the main body portion 10 is inserted into the lower end portion 403 of the integrated auxiliary device 401, the auxiliary device 401 is fixed to the upper surface of the main body portion 10, as shown in the right figure of Figure 11(a).
[0088] As shown in the left diagram of Fig. 11(b), the auxiliary tool 401 fixed to the main body part 10 is once slid upward, and then another auxiliary tool 411 is fixed to the upper surface of the main body part 10 in the same manner as the auxiliary tool 401. As shown in the right diagram of Fig. 11(b), the auxiliary tool 401 that has been retracted upward is slid downward, and the upper end part 402 of the auxiliary tool 411, which has the same shape as the neck part 10a, is inserted into the lower end part 403 of the auxiliary tool 401, whereby the auxiliary tool 401 and the auxiliary tool 411 are connected and fixed.
[0089] Fig. 11 is a view from the X-axis direction, so the entire width of tape body 100 is visible, but as explained in Fig. 9, tape body 100 is supported from both outsides in the X-axis direction by at least the inner side surfaces formed on the upper ends 402 of each of auxiliary tools 401, 411. For example, tape body 100 is supported by inner side surfaces formed in a region from the upper end of each of auxiliary tools 401, 411 to the lower end of an outer diameter enlarged region that forms a stepped shape. The inner side surfaces of auxiliary tools 401, 411 also restrict movement of tape body 100 in the Y-axis direction, so that the payout direction and retraction direction of tape body 100 are vertical.
[0090] The upper end 402 of each auxiliary tool 401, 411 supports the tape body 100 in the same manner as the payout opening 301 of the tape measure unit 300 described in Fig. 6. By attaching the auxiliary tools 401, 411, it is possible to obtain the same effect as moving the payout opening 301 upward. For example, attaching the auxiliary tool 401 having an axial length of 1 m creates the same situation as moving the main body 10 to a height of 1 m from the floor and paying out the tape body 100 at this position.
[0091] For example, if tape body 100 can be unwound to a height of 5 m without buckling, then attaching a 1 m auxiliary tool 401 will allow tape body 100 to be unwound to a height of 6 m. By connecting multiple auxiliary tools 401, tape body 100 can be unwound to an even higher position.
[0092] [Embodiment 2] 4 and 5 in the first embodiment, an example has been described in which the leveling of the table 90 and the movement of the tape measure unit 300 are performed manually, but these may be performed automatically. In the first embodiment, an example has been described in which the mark 250 projected onto the ceiling surface by the aiming device 210 is visually confirmed, but the inspection device 1 may be equipped with a camera that captures an image of the mark 250, and the mark 250 may be confirmed using the image captured by the camera.
[0093] In the second embodiment, an example of an inspection device 1 will be described that is equipped with a camera and automatically performs leveling of the table 90 and position adjustment of the tape measure unit 300. Below, the same components as those in the inspection device 1 of the first embodiment are given the same reference numerals, and the following mainly describes the points that are different from the inspection device 1 of the first embodiment.
[0094] Fig. 12 is a block diagram showing an example of a functional configuration of the inspection device 1 according to embodiment 2. In addition to the configuration shown in Fig. 4, the inspection device 1 shown in Fig. 12 includes a camera 75, a communication unit 80, a horizontal mechanism driving unit 83, and a movement mechanism driving unit 85. In addition to the configuration shown in Fig. 4, the control unit 50 shown in Fig. 12 includes a camera control unit 50d, a horizontal control unit 50e, and a position control unit 50f.
[0095] The camera 75 captures the mark 250 projected onto the ceiling surface by the aiming device 210 and the surrounding area. The communication unit 80 is used for wireless or wired communication with the camera 75 and an external device. The external device includes a communication terminal such as a smartphone or tablet equipped with a touch panel type liquid crystal display device.
[0096] Fig. 13 is a diagram showing an example of the internal configuration of the inspection device 1 according to embodiment 2. The inspection device 1 shown in Fig. 13 differs from the configuration shown in Fig. 5 in that it includes a camera 75, that it includes horizontal mechanism driving units 83 (83a-83c) instead of the dials 191-193, and that it includes movement mechanism driving units 85 (85a, 85b) instead of the handles 181, 182.
[0097] 13, camera 75 is provided in main body 220 of tester 200, similar to laser devices 210a and 210b constituting aiming device 210. Horizontal mechanism driving units 83a to 83c are provided corresponding to height adjustment screws 91 to 93, and are actuators such as motors that rotate each of height adjustment screws 91 to 93 forward and reverse. Movement mechanism driving units 85a and 85b are provided corresponding to movement mechanisms 81 and 82, and are actuators such as motors that rotate the screw shafts of each movement mechanism.
[0098] The camera control unit 50d performs wireless communication with the camera 75 having a wireless communication function via the communication unit 80, and acquires an image captured by the camera 75. The camera control unit 50d can display the image captured by the camera 75 on the display unit 32.
[0099] The camera control unit 50d can perform wireless communication with an external device via the communication unit 80 to display an image captured by the camera 75 on a display unit of the external device. For example, the camera control unit 50d can perform wireless communication with a communication terminal such as a smartphone or a tablet to display an image captured by the camera 75 on the screen of the communication terminal.
[0100] The user can check the positional relationship between the mark 250 captured by the camera 75 and the detector 2 on the display unit 32 or the display screen of an external device, and adjust the position of the main body 10 and the position of the pay-out outlet 301, i.e., the pay-out position of the tape body 100.
[0101] The horizontal control unit 50e controls the horizontal mechanism driving unit 83 based on the detection result of the inclination sensor 70 to level the table 90. When the vertical detection unit 50a determines based on the detection result of the inclination sensor 70 that the payout direction and the storage direction of the tape body 100 deviate from the vertical direction, the horizontal control unit 50e executes the leveling. The horizontal control unit 50e controls the horizontal mechanism driving units 83a to 83c to rotate the height adjustment screws 91 to 93 to perform the leveling. The horizontal control unit 50e calculates the rotation direction and the rotation amount of the height adjustment screws 91 to 93 based on the output value of the inclination sensor 70, and controls the horizontal mechanism driving units 83a to 83c based on the calculation result, so that the table 90 is automatically leveled, and the payout direction and the storage direction of the tape body 100 are adjusted to the vertical direction.
[0102] The position control unit 50f analyzes the image captured by the camera 75 to identify the positional relationship between the mark 250 and the detector 2, and controls the movement mechanism driving unit 85 based on the identification result. The position control unit 50f controls the movement mechanism driving unit 85 so that the center position of the tester 200 indicated by the mark 250, i.e., the payout position of the tape body 100, coincides with the center position of the detector 2.
[0103] Specifically, the position control unit 50f first rotates the screw shafts of the moving mechanisms 81 and 82 by a predetermined amount in a predetermined direction using the moving mechanism driving units 85a and 85b to specify the moving direction and amount of movement of the mark 250 on the captured image of the camera 75. The position control unit 50f calculates the rotation direction and amount of rotation of each screw shaft for moving the center position of the mark 250 to the center position of the sensor 2 based on the specified moving direction and amount of movement of the mark 250 and the direction and distance from the center position of the mark 250 on the captured image to the center position of the sensor 2. The position control unit 50f controls the moving mechanism driving units 85a and 85b based on the calculation result to move the tape measure unit 300, thereby automatically performing position adjustment to match the center position of the mark 250 with the center position of the sensor 2. The position control unit 50f may automatically perform position adjustment by feedback control that controls the moving mechanism driving units 85a and 85b while checking the captured image by the camera 75.
[0104] For example, when a user aligns the approximate position of the inspection device 1 with the sensor 2, locks the wheels 20, and performs a predetermined operation with the operation unit 31, the horizontal control unit 50e automatically performs the leveling of the table 90 as described above. After the table 90 becomes horizontal, that is, after the payout direction and retraction direction of the tape body 100 become vertical, the position control unit 50f then automatically performs the position adjustment of the tape measure unit 300 as described above.
[0105] After the table 90 is automatically adjusted to a horizontal state, the notification control unit 50b notifies the completion of leveling by the notification unit 33. After the position of the tape measure unit 300 is automatically adjusted by the position control unit 50f, the notification control unit 50b notifies the completion of position adjustment by the notification unit 33. The notification is performed by the notification unit 33 emitting a sound, emitting a light, or changing the light emission state. The completion of each process is notified to the user by emitting a different sound or emitting a different color light after the completion of leveling and after the completion of position adjustment.
[0106] For example, an illuminant such as an LED included in the notification unit 33 lights up red at first, changes to yellow after the leveling is completed, and changes to blue after the position adjustment is completed. When the color of the notification unit 33 turns blue, the user recognizes that the adjustment of the inspection device 1 is completed and can start the inspection work. Note that instead of or in addition to the notification by the notification unit 33, the notification may be made by displaying predetermined information on the display unit 32 or the display unit of a communication terminal connected for communication via the communication unit 80.
[0107] FIG. 14 is a flow chart showing an example of the flow of automatic processing executed by the inspection device 1 according to the second embodiment. The inspection device 1 judges the horizontal state of the table 90 (step S1). If the table 90 is not in a horizontal state (step S1; No), the inspection device 1 automatically adjusts the horizontal state (step S2). If the table 90 becomes horizontal (step S1; Yes), the inspection device 1 then judges whether or not the position of the tester 200, i.e., the payout position of the tape body 100, needs to be adjusted (step S3). The judgment is made by analyzing the captured image of the mark 250 and the detector 2 captured by the camera 75. If the position of the tester 200 needs to be adjusted (step S3; No), the inspection device 1 automatically adjusts the position (step S4). If there is no problem with the position of the tester 200 (step S3; Yes), the inspection device 1 ends the automatic processing.
[0108] Fig. 15 is a diagram for explaining a usage example of the inspection device 1 according to embodiment 2. In the example shown in Fig. 15, the main body 10 of the inspection device 1 has a case shape equipped with wheels 20 and a handle 11 like a suitcase, and an operation terminal 600, which is a tablet-type communication terminal, and a plurality of auxiliary tools 401 can be stored inside the case.
[0109] As shown in Fig. 15(a), the user holds the handle 11 and pulls the main body 10 to move to the inspection location of the detector 2. When the user arrives at the inspection location, he or she removes the operation terminal 600 and the assisting device 401 from the main body 10, as shown in Fig. 15(b). An image 620 captured by the camera 75 is displayed on a screen 610 of the operation terminal 600. While checking the screen of the operation terminal 600, the user aligns the approximate position of the main body 10 with the detector 2, and then locks the wheels 20 to fix the position of the main body 10 on the floor.
[0110] When the user performs a predetermined operation on the operation terminal 600, as described above, leveling of the table 90 is automatically performed inside the main body 10, and information 630 indicating completion of leveling is displayed on the screen 610. After that, position adjustment of the tape measure unit 300 is automatically performed inside the main body 10, and information 630 indicating completion of position adjustment is displayed on the screen 610.
[0111] Once leveling and position adjustment are complete, it becomes possible to operate buttons 640 on screen 610 of operation terminal 600 for raising and lowering tester 200. The user operates button 640 for raising tester 200 to inspect detector 2. After completing inspection, the user operates button 640 for lowering tester 200 to finish the inspection work.
[0112] During the inspection, the user attaches the auxiliary tool 401 to the tape body 100 as necessary. As described in FIG. 6, the payout / storage control unit 50c can calculate the payout amount of the tape body 100 when the drive unit 60 pays out the tape body 100. When the payout amount of the tape body 100 reaches a predetermined threshold, the notification control unit 50b notifies the user by displaying information indicating this on the screen of the operation terminal 600. Upon receiving the notification, the user can interrupt the lifting of the tester 200, attach the auxiliary tool 401, and then resume the lifting of the tester 200 to perform the inspection. For example, if there is a possibility that the tape body 100 will buckle when the payout amount reaches 5 m, the threshold can be set to 4 m to prompt the user to attach the auxiliary tool 401.
[0113] When the payout amount of tape body 100 reaches a predetermined threshold, the notification control unit 50b may issue a warning instructing the user to wear the assisting tool 401 to ensure safety. At the time of the warning, even if the user is operating the ascent button 640, the payout / storage control unit 50c may stop the payout of tape body 100 by the drive unit 60 and may not pay out tape body 100 until the user performs a predetermined operation to cancel the warning. After receiving the warning, the user can resume inspection by putting on the assisting tool 401 and canceling the warning.
[0114] Even after the auxiliary tool 401 is attached and the inspection is resumed, a notification or warning is issued to inform the user that additional auxiliary tool 401 needs to be attached, based on the payout amount of the tape body 100. For example, if there is a possibility that the tape body 100 will buckle when the payout amount reaches 5 m, a notification or warning is issued when the payout amount reaches 4 m, and after the user attaches 1 meter of the auxiliary tool 401, a notification or warning is issued again when the payout amount reaches 5 m. Each time a notification or warning is received, the user can add an auxiliary tool 401, connect it to the already attached auxiliary tool 401, and resume the inspection.
[0115] [Embodiment 3] The inspection device 1 may be an autonomous robot device that can move by itself to the installation location of the detector 2 and automatically performs the inspection. If the inspection can be performed automatically, even if multiple detectors 2 are installed in a building, each detector 2 can be easily inspected.
[0116] In the third embodiment, an example of an inspection device 1 that automatically performs inspection while moving autonomously will be described. Below, the same components as those in the inspection device 1 of the first and second embodiments are given the same reference numerals, and the following mainly describes the differences from the inspection device 1 of the second embodiment.
[0117] Fig. 16 is a block diagram showing a configuration example of the inspection device 1 according to embodiment 3. The inspection device 1 shown in Fig. 16 includes a traveling mechanism drive unit 87 in addition to the configuration shown in Fig. 12. The control unit 50 shown in Fig. 16 includes a traveling mechanism control unit 50g in addition to the configuration shown in Fig. 12.
[0118] The traveling mechanism drive unit 87 drives a traveling mechanism including a plurality of wheels 20 provided on the bottom surface of the main body 10, and rotates and drives at least one of the wheels 20 to move the inspection device 1 on its own. The traveling mechanism also includes a mechanism for changing the moving direction of the inspection device 1, and the traveling mechanism drive unit 87 can also change the moving direction of the inspection device 1. The traveling mechanism control unit 50g controls the traveling mechanism drive unit 87 to control the direction and amount of self-propelled movement of the inspection device 1.
[0119] 17 is a flowchart showing an example of the flow of automatic processing executed by the inspection device 1 according to the third embodiment. For example, when coordinate information indicating the installation positions of the multiple sensors 2 is registered in the storage unit 40, the inspection device 1 moves autonomously to the installation locations of the sensors 2 based on the coordinate information (step S11). The traveling mechanism control unit 50g controls the traveling mechanism driving unit 87 based on the coordinate information, whereby the inspection device 1 moves autonomously.
[0120] When the inspection device 1 arrives at the installation location of the detector 2, in steps S12 to S15, it automatically performs leveling of the table 90 and position adjustment of the tape measure unit 300. These processes are performed in the same manner as steps S1 to S4 described in FIG.
[0121] After completing the leveling of the table 90 and the position adjustment of the tape measure unit 300, the inspection device 1 raises the tester 200 to inspect the detector 2 (step S16). The payout / storage control unit 50c controls the drive unit 60 to raise the tester 200, thereby performing the inspection.
[0122] For example, the aiming device 210 may be provided with a laser device for measuring the distance to the ceiling surface in addition to the laser device for the mark 250, and the distance from the upper surface of the tester 200 to the ceiling surface may be measured, and the pay-out / storage control unit 50c may pay out the tape body 100 based on the measurement result, raise the tester 200, and perform the inspection. A pressure sensor capable of wireless communication via the communication unit 80 may be provided on the upper surface of the tester 200, and the pay-out / storage control unit 50c may detect that the tester 200 has come into contact with the ceiling surface based on the output value of the pressure sensor, stop the lifting of the tester 200, and perform the inspection. Information regarding the installation height of each detector 2 may be registered in the memory unit 40, and the pay-out / storage control unit 50c may pay out the tape body 100 based on the registered installation height.
[0123] When the inspection of the tester 200 is completed, the payout storage control unit 50c controls the drive unit 60 to lower the tester 200. If a detector 2 to be inspected remains (step S17; No), the travel mechanism control unit 50g controls the travel mechanism drive unit 87 based on the coordinate information of the next detector 2 registered in the storage unit 40, and the inspection device 1 travels by itself to the installation location of the next detector 2 (step S18). In this way, by repeating the processes of steps S12 to S18, the inspection device 1 sequentially inspects a plurality of detectors 2 while traveling by itself.
[0124] When the inspection of all the sensors 2 whose installation locations are registered in the memory unit 40 is completed (step S17; Yes), the inspection device 1 ends the process. For example, the inspection device 1 returns to the standby location before the start of the inspection and waits until the next inspection.
[0125] [Variations] 2, an example has been described in which the targeting device 210 is provided on the main body 220 of the tester 200 rotatably supported on the support 230, and the tester 200 is attached to and detached from the base 110 using the detachable part 240 on the bottom surface of the support 230, thereby changing the type of the tester 200. The method of changing the tester 200 is not limited to this. For example, as shown in FIG. 18, the type of the tester 200 may be changed by fixing the support 230, which rotatably supports the frame 260 provided with the targeting device 210, to the base 110, and attaching and detaching the tester 200 (200a, 200b) to and from the frame 260.
[0126] In FIG. 6, an example is described in which the drums are rotated in both of the two storage sections 320a, 320b, while among the rollers 310a, 310b, only one of the rollers 310b, 310b, is rotated. However, it is also possible to have an embodiment in which both rollers 310a, 310b are rotated.
[0127] For example, as shown in FIG. 19, a pair of gears 315 (315a, 315b) may be provided on the rotation shafts 311a, 311b of the rollers 310a, 310b, and both rollers 310a, 310b may be rotated by the driving unit 60a. When the rotation shaft 311b of the gear 315b is rotated by the driving unit 60a, the roller 310b and the gear 315b fixed on the shaft rotate. With the rotation of the gear 315b, the gear 315a rotates in the opposite direction at the same rotation speed as the gear 315b, and the roller 310a fixed to the rotation shaft 311a of the gear 315a rotates. That is, the rollers 310a and 310b rotate in the opposite directions at the same rotation speed by receiving the driving force from the driving unit 60a.
[0128] If the payout / storage control unit 50c controls the drive units 60a, 60b so that the feed speed of the long plates 100a, 100b by the roller 310 and the feed speed of the long plates 100a, 100b by the drum of the storage unit 320 are the same, and drives the roller 310 and the drum of the storage unit 320 to rotate, the tape body 100 can be paid out and stored more reliably.
[0129] Since both rollers 310a, 310b are driven to rotate, there is a possibility that the roller 310a continues to rotate even after the base 110 comes into contact with the pay-out opening 301 when storing the tape body 100, and the contact of the base 110 with the pay-out opening 301 cannot be detected by the stop of rotation of the roller 310a. In this case, for example, a sensor (not shown) may be provided to detect the load on the drive units 60a, 60b when the rollers 310a, 310b are driven to rotate, and the sensor may detect that the base 110 has come into contact with the pay-out opening 301 based on an increase in the load on the drive units 60a, 60b resulting in an overloaded state, and the drive units 60a, 60b may stop storing the tape body 100. For example, a rotation sensor provided on the rotating shaft 311a may be used to detect the pay-out and wind-up amounts of the tape body 100, and the drive units 60a, 60b may stop storing the tape body 100 based on the wind-up amount of the tape body 100 matching the pay-out amount.
[0130] Although an example has been described in which the drum of the storage section 320 is rotationally driven to store the long plates 100a, 100b, this does not exclude the use of a tape measure mechanism that uses an elastic member such as a spiral spring to store the long plates 100a, 100b as in the past. If the tape body 100 can be stored by the restoring force in the winding direction of the long plates 100a, 100b that an elastic member exerts on the drum as in the past, a conventional drum may be used without driving the drum by the driving section 60b. A drum that uses an elastic member such as a spiral spring may be rotationally driven by the driving section 60b as described above while utilizing the restoring force of the elastic member.
[0131] 8 to 11, an example has been described in which two members 401a and 401b having a substantially semi-cylindrical shape are assembled and integrated to form the assisting tool 401, but the configuration of the assisting tool 401 is not limited to this. For example, as shown in Fig. 20, the assisting tool may be realized by using a pipe 510 and a connector 501 (501a, 501b).
[0132] As shown in Fig. 20(a), two members 501a and 501b constituting the connector 501 include shafts 502a and 502b that can be inserted into the pipe 510 at both ends in the vertical direction. As with the auxiliary tool 401, as shown in Fig. 20(b), the members 501a and 501b are formed with a convex portion 504a and a concave portion 504b that are used for positioning and fixing.
[0133] As shown in Fig. 20(b), the upper and lower shafts 502a, 502b of the two members 501a, 501b are inserted into the pipe 510, and the convex portion 504a is inserted into the concave portion 504b to integrate them, thereby realizing an auxiliary tool for supporting the tape body 100. If the cylindrical pipe 510 is used, as shown in Fig. 20(c), the outer circumferential surface of the pipe 510 can be brought into contact with approximately the center in the width direction of the long plates 100a, 100b curved in the width direction (Y-axis direction), thereby supporting the long plates 100a, 100b.
[0134] For example, the auxiliary tool can be realized inexpensively and easily by selecting the outer diameter of a resin pipe 510 according to the curved shape of the long plates 100a, 100b and preparing a connector 501 having an axis 502 that matches the inner diameter of the pipe 510. A plurality of pipes 510 can also be used by connecting them in the vertical direction via the connector 501.
[0135] For example, as shown in FIG. 21, the neck 10a of the main body 10 can be shaped to include a cylindrical shaft 302 (302a, 302b) that is matched to the inner diameter of the pipe 510, and the shaft 302 can be inserted into the pipe 510 to be used as an auxiliary tool.
[0136] As shown in Fig. 21(a), the lower side of shaft 502 of connector 501, which has been assembled and integrated by sandwiching tape body 100, is inserted from the upper end of pipe 510. As shown in Fig. 21(b), by inserting the upper side of shaft 502 of connector 501 into another pipe 510 and connecting and fixing multiple pipes 510, the auxiliary tool can be easily extended upward.
[0137] 8 to 11, an example of the assisting tool 401 in which two members 401a, 401b are assembled and integrated has been described, but the two members 401a, 401b may be rotatably connected by a hinge-type connecting member 450 as shown in Fig. 22(a). Similarly, the connecting tool 501 constituting the assisting tool shown in Figs. 20 and 21 may be rotatably connected by a hinge-type connecting member 550 as shown in Fig. 22(b). By using the connecting members 450, 550, the work of attaching and detaching the assisting tool can be easily performed.
[0138] 6 and the like, an example in which the tape body 100 is composed of two long plates 100a, 100b has been described, but the tape body 100 may be composed of three or more long plates. For example, as shown in Fig. 23(a), both widthwise ends of three curved long plates 100a to 100c may be brought into contact with the widthwise ends of the adjacent long plates to be used as the tape body 100.
[0139] Three rollers 340 for feeding and storing are arranged corresponding to each of the long plates 100a to 100c. Three rollers 350 are arranged facing each roller 350 with the long plates 100a to 100c in between. A pair of rollers 340, 350 are arranged facing each other with their respective rotation axes 341, 351 parallel to each other on the same horizontal plane. By driving each roller 340 to rotate, the long plates 100a to 100c against which the outer circumferential surface of the roller is pressed can be fed and stored. By pressing the outer circumferential surface of the roller 340 against the long plates 100a to 100c and receiving it with the roller 350 arranged opposite to it, when the roller 340 is driven to rotate, the long plates 100a to 100c can be fed and stored while the roller 350 is rotated.
[0140] The rollers 340, 350 may be configured to include an outer periphery made of rubber or resin, similar to the roller 310 described in FIG. 7, and may rotate while deforming the outer periphery pressed against the long plates 100a-100c into a shape that conforms to the long plates 100a-100c. However, the rollers 340, 350 are not limited to having a rectangular outer shape as viewed from the top-bottom direction (Z-axis direction). For example, as shown in FIG. 23(b), the outer shape of the roller 340 may be a barrel shape that matches the curved cross-sectional shape of the long plates 100a-100c. The outer shape of the roller 350 may be a drum shape that matches the curved cross-sectional shape of the long plates 100a-100c.
[0141] When using a tape body 100 consisting of three long plates 100a to 100c as shown in FIG. 23, an auxiliary tool as shown in FIG. 24 may be used. The shape of the inner surface of the upper end 402 supporting the tape body 100 is made to match one long plate 100a at one upper end 402a, and to match two long plates 100b and 100c at the other upper end 402b, as shown in FIG. 24(a). This allows the long plates 100a to 100c to be supported from the outside along their respective curved shapes when the convex portion 404a is inserted into the concave portion 404b and integrated as shown in FIG. 24(b). The through hole of the payout port 301 described in FIG. 6(a) may also be made to have a triangular shape with each side curved inward, as in the shape shown in FIG. 24(b), so that the inner surface 301a of the payout port 301 supports each of the three long plates 100a to 100c from the outside along their respective curved shapes.
[0142] In this specification, a number of embodiments of the inspection device 1 have been described, but the contents described in each embodiment are not excluded from being realized in other embodiments. For example, the notification, warning, and removal work of the auxiliary tool 401 described in each embodiment may be performed by the inspection device 1 of other embodiments.
