Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described transport equipment, if the position of the power supply line support member (52) is deviated from the proper position, depending on the shape and structure of the power supply line support member (52), it may interfere with the transport vehicle. Similarly, if the power supply line (58) is positioned deviated from the proper position, it may interfere with the transport vehicle. Therefore, it is necessary to inspect whether the power supply line (58) and the power supply line support member (52) are positioned in the proper positions. However, the inspection trolley (2) described above can inspect the slack of the power supply line (58), but it cannot inspect whether the power supply line (58) is in the proper position in directions other than slack, or whether the power supply line support member (52) is in the proper position. Furthermore, if the distance over which the power supply line (58) and the power supply line support member (52) are positioned is long, the effort required to inspect the positions of the power supply line (58) and the power supply line support member (52) increases, so there is a need to make such inspections possible with less effort.

[0005] Therefore, there is a need for an inspection device that can check whether both the power supply line and the power supply line support member are in the correct position, and that can perform this inspection with minimal effort. [Means for solving the problem]

The inspection unit is configured to detect the first power supply line inspection unit and the second support member inspection unit, and the positions of both the second power supply line inspection unit and the second support member inspection unit relative to the trolley are fixed. The first inspection unit includes a first inspection body whose position relative to the trolley is fixed. The first power supply line inspection unit is configured such that, when the trolley is driven along the rail, the first power supply line passes without interference if the relative position of the first power supply line with respect to the rail is within the first reference range, and interferes if the relative position of the first power supply line with respect to the rail is outside the first reference range. The first groove is a through groove, and the first support member inspection unit is configured to inspect the arrangement of the first target portion formed in the first power supply line support member so as to be continuous in the direction of travel, and when the trolley is run along the rail, if the relative position of the first target portion with respect to the rail is within the second reference range, the first target portion passes through without interference, and if the relative position of the first target portion with respect to the rail is outside the second reference range, the first target portion interferes, the second inspection unit is configured to inspect the arrangement of the first target portion formed in the first inspection body so as to be continuous in the direction of travel, and the second inspection unit is configured to inspect the arrangement of the first target portion formed in the first inspection body so as to be continuous in the direction of travel, and when the trolley is run along the rail, if the relative position of the first target portion with respect to the rail is outside the second reference range, the first target portion interferes, the second groove is formed in the first inspection body so as to be continuous in the direction of travel, and the second inspection unit is configured to inspect the arrangement of the first target portion formed in the first inspection body so as to be continuous in the direction of travel, and when the trolley is run along the rail, if the relative position of the first target portion with respect to the rail is within the second reference range, the first target portion passes through without interference, and the second inspection unit is configured to inspect the arrangement of the first target portion formed in the first inspection body so as to be continuous in the direction of travel, and the second groove is a through groove formed in the first inspection body so as to be continuous in the direction of travelThe second inspection body is fixed in position relative to the trolley, and the second power supply line inspection section is a third groove formed in the second inspection body that penetrates in the direction of travel, such that when the trolley is run along the rail, the second power supply line passes through without interference if its relative position to the rail is within the first reference range, and interferes if its relative position to the rail is outside the first reference range.

[0007] In this configuration, the positions of both the power supply line inspection section and the support member inspection section are fixed to a trolley, which is positioned vertically relative to the rail by running wheels and horizontally relative to the rail by guide wheels. Therefore, while the trolley is moving in the direction of travel, the relative positions of the power supply line inspection section and the support member inspection section with respect to the rail are maintained within a certain range at each position in the direction of travel. Thus, by moving the inspection device's trolley along the rail, it is possible to continuously inspect whether the relative positions of both the power supply line and the power supply line support member with respect to the rail are within the appropriate range at each position in the direction of travel. Consequently, the effort required to inspect the relative positions of the power supply line and the power supply line support member with respect to the rail can be reduced. Furthermore, with this configuration, when a pair of left and right power supply lines are arranged along the rail, and each power supply line is supported by a power supply line support member, it is possible to simultaneously inspect whether the relative positions of both the left and right power supply lines and the power supply line support members with respect to the rail are within the appropriate range by running the trolley along the rail. Therefore, even when a pair of left and right power supply lines are arranged along the rail, the effort required to inspect the relative positions of the pair of power supply lines and power supply line support members with respect to the rail can be reduced. In addition, with this configuration, it is possible to easily inspect whether the relative positions of both the power supply lines and power supply line support members with respect to the rail are within the appropriate range by checking for interference between the first and second inspection objects and the target parts of the power supply lines and power supply line support members when the trolley is running along the rail. Therefore, the effort required to inspect the relative positions of the power supply lines and power supply line support members with respect to the rail can be reduced.

[0009] The following describes an embodiment of the inspection device for conveying equipment with reference to the drawings.

[0010] In the following description, the inspection device 30 of the transport equipment 20 according to the embodiment will be explained with reference to the drawings. Figure 1 is a front view of the rails 21 and transport vehicle 11 of the transport equipment 20. The transport equipment 20 is equipped with rails 21 that guide the movement of the transport vehicle 11. The transport equipment 20 is also equipped with a first power supply line 22a arranged along the rails 21 that supplies power to the transport vehicle 11. In this embodiment, the transport vehicle 11 is an overhead transport vehicle, and the rails 21 are fixed to, for example, a beam 19. The transport vehicle 11 is also an electrically powered unmanned transport vehicle. In this embodiment, the transport equipment 20 is installed indoors, for example, in a clean room. The transport equipment 20 is, for example, a transport equipment that transports a container containing multiple glass substrates for displays as an item W.

[0011] Here, the vertical direction is defined as the up-and-down direction Z. The direction in which the transport vehicle 11 travels is defined as the travel direction X. The travel direction X is the same as the direction in which the trolley 32 of the inspection device 30, which will be described later, travels. The direction perpendicular to the travel direction X when viewed from above is defined as the width direction Y. One side of the width direction Y is defined as the first width direction Y1, and the other side of the width direction Y is defined as the second width direction Y2. The aforementioned first power supply line 22a corresponds to the power supply line. The first power supply line support member 23a, described later, corresponds to the power supply line support member, the first inspection unit 40a corresponds to the inspection unit, the first power supply line inspection section 41a corresponds to the power supply line inspection section, and the first support member inspection section 42a corresponds to the support member inspection section.

[0012] The rail 21 has a running surface 21u facing upward and a guide surface 21s facing in the width direction Y. In this embodiment, the rail 21 comprises a first rail body 21a and a second rail body 21b arranged spaced apart in the width direction Y. The first rail body 21a is positioned on the first side Y1 in the width direction, and the second rail body 21b is positioned on the second side Y2 in the width direction. In the illustrated example, the cross-sections of the first rail body 21a and the second rail body 21b are L-shaped. Furthermore, the upper surface of the lower L-shaped portion of the cross-section of the first rail body 21a and the second rail body 21b is the running surface 21u, and the side surface of the higher L-shaped portion is the guide surface 21s. Furthermore, the lower L-shaped portion of the cross-section of the first rail body 21a is positioned on the second side Y2 in the width direction than the higher portion, and the lower L-shaped portion of the cross-section of the second rail body 21b is positioned on the first side Y1 in the width direction than the higher portion.

[0013] In this embodiment, the first power supply line 22a is positioned on the first side Y1 in the width direction relative to the first rail body 21a. The first power supply line support member 23a, which supports the first power supply line 22a, is also positioned on the first side Y1 in the width direction relative to the first rail body 21a. In this embodiment, the second power supply line 22b is positioned on the second side Y2 in the width direction relative to the second rail body 21b. The second power supply line support member 23b, which supports the second power supply line 22b, is also positioned on the second side Y2 in the width direction relative to the second rail body 21b.

[0014] The transport vehicle 11 comprises a running section 12 and a holding section 13 for holding the article W. The holding section 13 for holding the article W is supported by the running section 12 on its upper side. The running section 12 is equipped with running wheels 15 that roll on a running surface 21u. The running section 12 is also equipped with guide wheels (16c, 16d) that roll on a guide surface 21s.

[0015] In this embodiment, the guide wheels (16c, 16d) are repositionable between a contact position where they can contact the guide surface 21s and a non-contact position where they cannot contact the guide surface 21s. The guide wheels (16c, 16d) guide the transport vehicle 11 along the guide surface 21s of the rail 21 by contacting the guide surface 21s of the rail 21, for example, at a branching point of the rail 21. The guide wheels (16c, 16d) include a first guide wheel 16c that contacts the rail 21 from a first side Y1 in the width direction and a second guide wheel 16d that contacts the rail 21 from a second side Y2 in the width direction.

[0016] In this embodiment, the transport vehicle 11 is equipped with a power receiving unit 17 that receives power from the first power supply line 22a of the transport equipment 20 in a non-contact manner. In the illustrated example, the power receiving unit 17 is provided on both sides of the transport vehicle 11 in the width direction Y so that the transport vehicle 11 can receive power from the first power supply line 22a and the second power supply line 22b. The power received by the power receiving unit 17 is supplied to various devices mounted on the transport vehicle 11, such as the drive unit for the traveling wheels 15, the transfer device for the goods W, the control device, the transmitting and receiving device, the detection device, and the energy storage device. In this embodiment, at least two first power supply lines 22a are provided and are arranged to sandwich the power receiving unit 17 in the vertical direction Z. Also, at least two second power supply lines 22b are provided and are arranged to sandwich the power receiving unit 17 in the vertical direction Z.

[0017] FIG. 2 is a perspective view of the first power supply line 22a and the first power supply line support member 23a of the conveying facility 20. The conveying facility 20 includes a first power supply line support member 23a that supports the first power supply line 22a such that the relative position of the first power supply line 22a with respect to the rail 21 is fixed. In the present embodiment, the conveying facility 20 includes a first power supply line position adjustment mechanism 25a that can change and fix the relative position of the first power supply line 22a with respect to the rail 21.

[0018] In the present embodiment, the first power supply line support member 23a is supported by a first fixing member 24a whose relative position with respect to the rail 21 is fixed. Further, the first power supply line position adjustment mechanism 25a is configured to be able to change the position of the first power supply line support member 23a with respect to the first fixing member 24a. In this way, by changing the relative position of the first power supply line support member 23a with respect to the first fixing member 24a by the first power supply line position adjustment mechanism 25a, the position of the first power supply line 22a can be adjusted. In the illustrated example, the first power supply line support member 23a is supported by a first fixing member 24a whose relative position with respect to the first rail body 21a is fixed. Further, the first power supply line position adjustment mechanism 25a is used, for example, by a working entity performing inspection by the inspection device 30 to adjust the position of the first power supply line 22a or the first power supply line support member 23a. In this way, while the inspection device 30 travels along the rail 21, inspection by the inspection device 30 and adjustment by the first power supply line position adjustment mechanism 25a can be performed, and after adjustment, there is no need for the inspection device 30 to travel again along the entire rail 21 of the travel path for inspection, and the number of travel times of the inspection device 30 can be reduced. Note that the "working entity" is, for example, one or both of an operator and a working device. The working device includes at least one of a traveling device that travels the inspection device 30 and a determination device that determines the inspection result by the inspection device 30.

[0019] In this embodiment, the first power supply line position adjustment mechanism 25a has an elongated hole 25c provided on one side of the first power supply line support member 23a and the first fixing member 24a, and a fastening member 25d inserted through the elongated hole 25c, and is configured to change the relative position of the first power supply line support member 23a in the vertical direction Z with respect to the first fixing member 24a. The first power supply line position adjustment mechanism 25a also includes an adjustment member 25e that can adjust the relative position of the first power supply line support member 23a and the first fixing member 24a in the vertical direction Z. In the illustrated example, the fastening member 25d is a mounting bolt. The adjustment member 25e is a push bolt that presses the first power supply line support member 23a upward. In this way, by providing the adjustment member 25e, excessive load is not applied to the fastening member 25d, so that the position adjustment work of the first power supply line 22a can be performed easily and with high precision, and bending of the fastening member 25d is less likely to occur.

[0020] In this embodiment, the transport equipment 20 is equipped with a second power supply line position adjustment mechanism 25b that can change and fix the relative position of the second power supply line 22b with respect to the rail 21. In this embodiment, the second power supply line support member 23b is supported by a second fixing member 24b whose relative position with respect to the rail 21 is fixed. The second power supply line position adjustment mechanism 25b has the same structure as the first power supply line position adjustment mechanism 25a described above.

[0021] FIG. 3 is a front view showing the rail 21 of the conveying equipment 20 and the inspection device 30. FIG. 4 is an enlarged front view of the rail 21 of the conveying equipment 20 and the inspection device 30. The conveying equipment 20 includes an inspection device 30. The inspection device 30 includes a carriage 32 that travels along the rail 21, a traveling wheel 33 supported by the carriage 32, and a guide wheel 34 supported by the carriage 32. The traveling wheel 33 is configured to position the carriage 32 in the vertical direction Z with respect to the rail 21 by rolling on a traveling surface 21u facing the upper side of the rail 21. The guide wheel 34 is configured to position the carriage 32 in the width direction Y with respect to the rail 21 by rolling on a guide surface 21s facing the width direction Y of the rail 21. Further, the inspection device 30 includes a first inspection unit 40a. In the present embodiment, the first inspection unit 40a includes a first inspection body 43a whose position with respect to the carriage 32 is fixed.

[0022] The first inspection unit 40a includes a first power supply line inspection unit 41a that inspects the arrangement of the first power supply line 22a. The first power supply line inspection unit 41a is configured to detect whether or not the relative position of the first power supply line 22a with respect to the rail 21 is within a predetermined first reference range D1. In the present embodiment, when the carriage 32 is caused to travel along the rail 21, if the relative position of the first power supply line 22a with respect to the rail 21 is within the first reference range D1, the first power supply line 22a passes without interference, and if the relative position of the first power supply line 22a with respect to the rail 21 is outside the first reference range D1, the first power supply line 22a interferes. It is a first concave groove penetrating in the traveling direction X formed in the first inspection body 43a. In the illustrated example, the first concave groove, which is the first power supply line inspection unit 41a, is formed so as to have a bottom portion on the second side Y2 in the width direction.

[0023] Furthermore, the first inspection unit 40a includes a first support member inspection unit 42a for inspecting the arrangement of the first power supply line support member 23a. The first support member inspection unit 42a is configured to detect whether the relative position of the first power supply line support member 23a with respect to the rail 21 is within a predetermined second reference range D2. In this embodiment, the first support member inspection unit 42a is configured to inspect the arrangement of the first target portion 90a (described later) formed in the first power supply line support member 23a so as to be continuous with the running direction X. Furthermore, the first support member inspection section 42a is a second groove formed in the first inspection body 43a that penetrates in the direction of travel X, such that when the trolley 32 is run along the rail 21, the first target section 90a passes through without interference if its relative position to the rail 21 is within the second reference range D2, and interferes if its relative position to the rail 21 is outside the second reference range D2. In the illustrated example, the second groove, which is the first support member inspection section 42a, is formed to have a bottom facing upward.

[0024] In this embodiment, the predetermined first reference range D1 for the relative position of the first power supply line 22a with respect to the rail 21 is a predetermined range for the relative position of the first power supply line 22a with respect to the running surface 21u of the first rail body 21a in the vertical direction Z, and for the relative position of the first power supply line 22a with respect to the guide surface 21s of the first rail body 21a in the width direction Y. In this embodiment, detection of whether or not the position is within the above first reference range D1 is performed by checking for contact between the first power supply line 22a and the first power supply line inspection unit 41a, or by detection by the operator (for example, by visual inspection by the operator). In the example shown in Figure 4, only the range in the vertical direction Z of the first reference range D1 is shown.

[0025] In this embodiment, the predetermined second reference range D2 for the relative position of the first power supply line support member 23a with respect to the rail 21 is a predetermined range for the relative position of the first power supply line support member 23a with respect to the running surface 21u of the first rail body 21a in the vertical direction Z, and for the relative position of the first power supply line support member 23a with respect to the guide surface 21s of the first rail body 21a in the width direction Y. In this embodiment, detection of whether or not the position is within the above second reference range D2 is performed by checking for contact between the first power supply line support member 23a and the first support member inspection unit 42a, or by detection by the operator (for example, by visual inspection by the operator). In the example shown in Figure 4, only the width direction Y range in the second reference range D2 is shown.

[0026] In this embodiment, the positions of both the first power supply line inspection unit 41a and the first support member inspection unit 42a with respect to the trolley 32 are fixed. This allows the relative positions of the first power supply line inspection unit 41a and the first support member inspection unit 42a with respect to the rail 21 to be kept constant while the trolley 32 of the inspection device 30 is in motion.

[0027] In this embodiment, the transport equipment 20 is positioned on the second side Y2 in the width direction relative to the second rail body 21b and includes a second power supply line 22b that supplies power to the transport vehicle 11. The transport equipment 20 also includes a second power supply line support member 23b positioned on the second side Y2 in the width direction relative to the second rail body 21b and supports the second power supply line 22b so that the relative position of the second power supply line 22b with respect to the rail 21 is fixed. In the illustrated example, the second power supply line support member 23b supports the second power supply line 22b so that the relative position of the second power supply line 22b with respect to the second rail body 21b is fixed.

[0028] In this embodiment, the inspection device 30 further comprises a second inspection unit 40b. The second inspection unit 40b comprises a second inspection body 43b whose position is fixed relative to the trolley 32. In this embodiment, the second inspection unit 40b is supported by the trolley 32.

[0029] In this embodiment, the second inspection unit 40b includes a second power supply line inspection section 41b for inspecting the arrangement of the second power supply line 22b. The second power supply line inspection section 41b is configured to detect whether the relative position of the second power supply line 22b with respect to the rail 21 is within a first reference range D1. In this embodiment, the second power supply line inspection section 41b is a third groove formed in the second inspection body 43b that penetrates in the direction of travel X, such that when the trolley 32 is run along the rail 21, the second power supply line 22b passes through without interference if its relative position with respect to the rail 21 is within the first reference range D1, and interferes if its relative position with respect to the rail 21 is outside the first reference range D1. In the illustrated example, the third groove, which is the second power supply line inspection section 41b, is formed to have a bottom on the first side Y1 in the width direction.

[0030] In this embodiment, the second inspection unit 40b includes a second support member inspection unit 42b for inspecting the arrangement of the second power supply line support member 23b. The second support member inspection unit 42b is configured to detect whether the relative position of the second power supply line support member 23b with respect to the rail 21 is within the second reference range D2. In addition, in this embodiment, the second support member inspection unit 42b is configured to inspect the arrangement of the second target portion 90b (described later) formed in the second power supply line support member 23b so as to be continuous with the running direction X. Furthermore, the second support member inspection section 42b is a fourth groove formed in the second inspection body 43b that penetrates in the direction of travel X, such that when the trolley 32 is run along the rail 21, the second target section 90b passes through without interference if its relative position to the rail 21 is within the second reference range D2, and interferes if its relative position to the rail 21 is outside the second reference range D2. In the illustrated example, the fourth groove, which is the second support member inspection section 42b, is formed to have a bottom facing upward.

[0031] In this embodiment, the first reference range D1, which is a predetermined range for the relative position of the second power supply line 22b with respect to the rail 21, is a predetermined range for the relative position of the second power supply line 22b with respect to the running surface 21u of the second rail body 21b in the vertical direction Z, and for the relative position of the second power supply line 22b with respect to the guide surface 21s of the second rail body 21b in the width direction Y. In this embodiment, detection of whether or not the position is within the first reference range D1 is performed by checking for contact between the second power supply line 22b and the second power supply line inspection unit 41b, or by detection by the operator (for example, by visual inspection by the operator).

[0064] [Summary of the above embodiment] The inspection equipment for the conveying equipment described above will be explained below.

[0065] The inspection device for transport equipment according to the present disclosure comprises: a rail for guiding the movement of a transport vehicle; a power supply line arranged along the rail for supplying power to the transport vehicle; and a power supply line support member that supports the power supply line so as to fix the relative position of the power supply line with respect to the rail, wherein the inspection device comprises: a trolley that travels along the rail; running wheels supported on the trolley; guide wheels supported on the trolley; and an inspection unit, wherein the direction in which the trolley travels is defined as the travel direction, and the direction perpendicular to the travel direction in an up-and-down view is defined as the width direction, and the running wheels are configured to position the trolley vertically with respect to the rail by rolling on a running surface facing the upper side of the rail, and the present invention The inner ring is configured to position the trolley in the width direction relative to the rail by rolling on a guide surface of the rail facing the width direction, and the inspection unit comprises a power supply line inspection unit for inspecting the arrangement of the power supply line and a support member inspection unit for inspecting the arrangement of the power supply line support member, the power supply line inspection unit is configured to detect whether the relative position of the power supply line with respect to the rail is within a predetermined first reference range, and the support member inspection unit is configured to detect whether the relative position of the power supply line support member with respect to the rail is within a predetermined second reference range, and the positions of both the power supply line inspection unit and the support member inspection unit with respect to the trolley are fixed.

[0066] In this configuration, the positions of both the power supply line inspection section and the support member inspection section are fixed to a trolley, which is positioned vertically relative to the rail by running wheels and horizontally relative to the rail by guide wheels. Therefore, while the trolley is moving in the direction of travel, the relative positions of the power supply line inspection section and the support member inspection section with respect to the rail are maintained within a certain range at each position in the direction of travel. Thus, by moving the inspection device's trolley along the rail, it is possible to continuously inspect whether the relative positions of both the power supply line and the power supply line support member with respect to the rail are within the appropriate range at each position in the direction of travel. Consequently, the effort required to inspect the relative positions of the power supply line and the power supply line support member with respect to the rail can be reduced.

[0067] In one embodiment, the power supply line is designated as the first power supply line, the power supply line support member as the first power supply line support member, the inspection unit as the first inspection unit, the power supply line inspection section as the first power supply line inspection section, the support member inspection section as the first support member inspection section, with one side in the width direction designated as the first side in the width direction and the other side in the width direction designated as the second side in the width direction, the first power supply line and the first power supply line support member are arranged on the first side in the width direction with respect to the rail, and the transport equipment is arranged on the second side in the width direction with respect to the rail, and includes a second power supply line that supplies power to the transport vehicle and a second power supply line that supports the second power supply line so as to fix the relative position of the second power supply line with respect to the rail. Preferably, the trolley comprises a support member, the trolley further supports a second inspection unit, the second inspection unit comprises a second power supply line inspection unit for inspecting the arrangement of the second power supply line, and a second support member inspection unit for inspecting the arrangement of the second power supply line support member, the second power supply line inspection unit is configured to detect whether the relative position of the second power supply line with respect to the rail is within the first reference range, the second support member inspection unit is configured to detect whether the relative position of the second power supply line support member with respect to the rail is within the second reference range, and the positions of both the second power supply line inspection unit and the second support member inspection unit with respect to the trolley are fixed.

[0068] According to this configuration, when a pair of left and right power supply lines are arranged along the rail and each power supply line is supported by a power supply line support member, it is possible to simultaneously inspect whether the relative positions of both the left and right power supply lines and the power supply line support members with respect to the rail are within the appropriate range by running the trolley along the rail. Therefore, even when a pair of left and right power supply lines are arranged along the rail, the effort required to inspect the relative positions of the pair of power supply lines and power supply line support members with respect to the rail can be reduced.

[0069] In one embodiment, the first inspection unit comprises a first inspection body whose position relative to the trolley is fixed, the first power supply line inspection section is a first groove formed in the first inspection body that penetrates in the direction of travel, such that when the trolley is traveled along the rail, the first power supply line passes through without interference if the relative position of the first power supply line with respect to the rail is within a first reference range, and the first power supply line interferes if the relative position of the first power supply line with respect to the rail is outside the first reference range, the first support member inspection section is configured to inspect the arrangement of a first target portion formed in the first power supply line support member to be continuous in the direction of travel, and is a second groove formed in the first inspection body that penetrates in the direction of travel, such that when the trolley is traveled along the rail, the first target portion passes through without interference if the relative position of the first target portion with respect to the rail is within a second reference range, and the first target portion interferes if the relative position of the first target portion with respect to the rail is outside the second reference range, The second inspection unit preferably comprises a second inspection body whose position relative to the trolley is fixed, and the second power supply line inspection section is a third groove formed in the second inspection body that penetrates in the direction of travel, such that when the trolley is run along the rail, the second power supply line passes through without interference if the relative position of the second power supply line with respect to the rail is within the first reference range, and the second power supply line interferes if the relative position of the second power supply line with respect to the rail is outside the first reference range, and the second support member inspection section is configured to inspect the arrangement of a second target portion formed in the second power supply line support member to be continuous in the direction of travel, and is a fourth groove formed in the second inspection body that penetrates in the direction of travel, such that when the trolley is run along the rail, the second target portion passes through without interference if the relative position of the second target portion with respect to the rail is within the second reference range, and the second target portion interferes if the relative position of the second target portion with respect to the rail is outside the second reference range.

[0070] With this configuration, it is possible to easily check whether the relative positions of both the power supply line and the power supply line support member with respect to the rail are within the appropriate range by checking for interference between the first and second inspection bodies and the target parts of the power supply line and power supply line support member when the trolley is run along the rail. Therefore, the effort required to check the relative positions of the power supply line and power supply line support member with respect to the rail can be reduced.

[0072] With this configuration, when an optical transmission device is positioned along a rail, it is possible to inspect whether the optical transmission device is positioned within the appropriate range simultaneously with the inspection of the power supply line and power supply line support members. Therefore, the effort required to inspect the relative positions of the power supply line, power supply line support members, and optical transmission device with respect to the rail can be reduced.

[0073] In one embodiment, the rail comprises a first rail body and a second rail body arranged spaced apart in the width direction, and further comprises a rail spacing measuring device supported by the trolley for measuring the distance between the first rail body and the second rail body.

[0074] With this configuration, by running the trolley along the rails, it is possible to continuously inspect whether the widthwise spacing of a pair of rail bodies constituting the rails is within the appropriate range, simultaneously with the inspection of the power supply lines and power supply line support members, at each position in the direction of travel. Therefore, the effort required to inspect the widthwise spacing of a pair of rail bodies can be reduced.

[0075] In one embodiment, the guide wheel preferably includes a first guide wheel that contacts the rail from a first widthwise side, which is one side in the widthwise direction, and a second guide wheel that contacts the rail from a second widthwise side, which is the other side in the widthwise direction, and is supported by the trolley and further comprises a widthwise adjustment mechanism for moving the position in the widthwise direction of at least one of the first guide wheel and the second guide wheel.
