Description

[Technical field]

[0001] The present invention relates to an article transport vehicle that transports articles. [Background technology]

[0002] For example, Japanese Patent Application Laid-Open No. 2018-118809 (Patent Document 1) discloses a technology related to an article transport vehicle. In the following description of the background art, the reference numerals in parentheses refer to those in Patent Document 1.

[0003] The article transport vehicle of Patent Document 1 includes a running section (running body 9) that runs along a running direction (forward / rearward direction FR), and a vehicle body (transport vehicle main body 10) that is supported by being suspended from the running section and forms a storage section for storing articles (articles 90). The vehicle body includes body covers (30) that are arranged on both outer sides in the running direction with respect to the storage section. The body cover (30) is formed with a storage space (equipment storage space E) that stores electric equipment (50) including a control device.

[Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-118809 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the article transport vehicle of Patent Document 1, a plate-shaped bracket (equipment support frame 33) is arranged in the storage space. Different electrical equipment (50) can be attached to both sides of the bracket (the side facing the base member and the side facing the cover). The bracket also has through holes (35) formed therein, and the electrical equipment (50) attached to each side of the bracket can be connected to each other by inserting a cable through the through holes (35).

[0006] Incidentally, a plurality of cables are accommodated in the above-mentioned accommodation space. When a large number of cables are accommodated or when each cable is relatively long, the arrangement of the cables in the accommodation space is likely to become complicated, and there is room for improvement in terms of the efficiency of space utilization in the accommodation space and the efficiency of wiring work. In addition, if the plurality of cables are not properly held, when the cover is not attached, the plurality of cables are likely to bend so as to protrude outside the accommodation space, which is likely to interfere with the work of attaching the cover after wiring work or the maintenance work on the control device in the accommodation space.

[0007] It is therefore desirable to have an article transport vehicle with a vehicle body that can adequately accommodate the cables and control devices. [Means for solving the problem]

[0008] The article transport vehicle according to the present disclosure is an article transport vehicle that transports articles, A vehicle body is supported by the running part and forms a storage part for storing the article. The vehicle body includes a target wall portion that constitutes at least a part of a wall facing the storage portion, the target wall portion includes a base member, a cover attached to the base member to form an accommodation space for accommodating a control device between the cover and the base member, and a bracket attached to the base member and disposed in the accommodation space, The control device is attached to at least one of the base member and the bracket, With the control device accommodated in the accommodation space, a wiring space is formed between the bracket and the base member in which a portion of the cable accommodated in the accommodation space is disposed.

[0009] According to this configuration, the control device and the cable can be appropriately accommodated within the accommodation space between the base member and the cover in the target wall portion of the vehicle body. Furthermore, with this configuration, a wiring space in which cables are arranged is formed between the bracket and the base member within the housing space, so that multiple cables can be stored in the wiring space between the bracket and the base member and the cables can be prevented from protruding out towards the cover, which makes it easy to perform tasks such as wiring the cables and assembling the cover to the base member after the wiring task.

[0010] Further features and advantages of the article transport vehicle will become apparent from the following description of exemplary, non-limiting embodiments which are given with reference to the drawings, in which: FIG. [Brief description of the drawings]

[0012] Hereinafter, an embodiment of the article transport vehicle will be described with reference to the drawings. As shown in FIG. 1, an article transport vehicle 1 for transporting an article W includes a running section 4 having wheels 3, and a vehicle body 2 supported by the running section 4 and forming a storage section 9 for storing the article W. In this embodiment, the article transport vehicle 1 is configured to transport the article W along a preset travel path. In this example, the article W is a container (FOUP: Front Opening Unified Pod) for storing a semiconductor substrate. The article transport vehicle 1 transports the article W to a processing device that processes the semiconductor substrate. The article transport vehicle 1 may also transport the article W to a storage shelf or the like that stores the article W. The article W may be a reticle storage container (so-called reticle pod) for storing a reticle, other than a FOUP.

[0013] As shown in FIG. 1 and FIG. 2, the traveling unit 4 includes a plurality of wheels 3. The wheels 3 roll on a traveling rail R1 provided along a traveling path. The traveling unit 4 includes a traveling motor M1 for rotating the wheels 3. At least one of the plurality of wheels 3 is driven to rotate by the traveling motor M1, so that the traveling unit 4 travels along the traveling rail R1. In this example, the traveling rail R1 is supported by being suspended from the ceiling C, and the traveling path is formed along the ceiling C. That is, in this example, the article transport vehicle 1 is a ceiling transport vehicle. Note that the article transport vehicle 1 may be a transport vehicle other than a ceiling transport vehicle (for example, a transport vehicle that travels autonomously on the floor surface, a transport vehicle that travels while being guided by rails or the like provided on the floor surface, an automatic sorting cart that sorts articles while traveling in an automated warehouse, a stacker crane, etc.).

[0014] In the example of FIG. 1 and FIG. 2, a pair of running rails R1 are provided. The running unit 4 further includes a guide wheel 41 and a guide auxiliary wheel 42. The guide auxiliary wheel 42 abuts against the inner side surface of the pair of running rails R1. The guide wheel 41 abuts against a guide rail R2 suspended from a ceiling C. The guide rail R2 is disposed in a branching section or a merging section of the running route. The guide wheel 41 is configured to be movable between a right guide position where the guide rail R2 abuts from the right side and a left guide position where the guide rail R2 abuts from the left side. The running unit 4 travels along an arbitrary running route in a branching section or a merging section by moving the guide wheel 41 to either the right guide position or the left guide position.

[0015] The vehicle body 2 is supported by being suspended from the traveling section 4. In this example, the vehicle body 2 is disposed below the traveling rail R1 (below the traveling section 4 across the traveling rail R1). The vehicle body 2 holds the article W and transfers the article W to the transport location. In this embodiment, the vehicle body 2 is provided with a holding section 8 that holds the article W. The holding section 8 supports the article W by suspending it. The holding section 8 is configured to be able to rise and fall relative to the traveling section 4. When the traveling section 4 is traveling, the holding section 8 is disposed in an elevated position. When the article W is transferred to the transport location, the holding section 8 is disposed in a lowered position. The elevated position is a position where the article W held by the holding section 8 is stored in the storage section 9. The lowered position is a position below the elevated position, where the holding section 8 receives the article W placed at the transport location and delivers the article W to the transport location. In this example, the vehicle body 2 is provided with a lifting section 16. The lifting unit 16 includes a drum, a belt wound around the drum and connected to the holding unit 8 at its tip, and a lifting motor M2 (FIG. 1) that rotates the drum to drive the belt. The lifting unit 16 lifts and lowers the holding unit 8 between the raised position and the lowered position as described above by rotating the drum by driving the lifting motor M2.

[0016] In the following, the width direction of the body 2 of the article transport vehicle 1 (the direction in which the pair of traveling rails R1 are aligned) is referred to as the first direction X, the up-down direction along the up-down direction is referred to as the second direction Z, and the direction perpendicular to the width direction when viewed in the up-down direction, i.e., the front-to-rear direction of the body of the article transport vehicle 1, is referred to as the third direction Y. Furthermore, one side of the first direction X is referred to as the first direction first side X1, the other side of the first direction X is referred to as the first direction second side X2, the rear side of the body 2 in the third direction Y is referred to as the third direction first side Y1, and the opposite side (the front side of the body 2) is referred to as the third direction second side Y2.

[0017] As shown in Figs. 1 to 3, the vehicle body 2 has a target wall portion 10 which is a portion constituting at least a part of the wall facing the storage section 9. In this embodiment, the target wall portion 10 is provided adjacent to one side of the storage section 9 in the third direction Y. The target wall portion 10 is also arranged so as to cover the storage section 9 from one side in the third direction Y. In this example, the target wall portion 10 is arranged on the third direction first side Y1 (the rear side of the vehicle body 2) with respect to the storage section 9. Then, when an item W is stored in the storage section 9, the target wall portion 10 overlaps with the item W when viewed in the third direction Y.

[0018] 1 to 3, the car body 2 is provided with a cover portion 14. The cover portion 14 is provided so as to cover the storage portion 9 from both sides in the third direction Y and from above. The cover portion 14 is also provided so as to cover the lifting portion 16 and the holding portion 8 in the raised position. In this example, the cover portion 14 is disposed below the traveling rail R1.

[0019] The cover portion 14 includes a first cover portion 14a disposed on a first side Y1 in the third direction (rear side of the vehicle body 2) with respect to the storage portion 9, a second cover portion 14b disposed on a second side Y2 in the third direction (front side of the vehicle body 2) with respect to the storage portion 9, and a connecting portion 20 connecting the first cover portion 14a and the second cover portion 14b. The connecting portion 20 connects an upper end portion of the first cover portion 14a to an upper end portion of the second cover portion 14b. In the illustrated example, the connecting portion 20 is a member formed in a rectangular shape when viewed in the up-down direction. In this example, the first cover portion 14a covers the storage portion 9 from the first side Y1 in the third direction, the second cover portion 14b covers the storage portion 9 from the second side Y2 in the third direction, and the connecting portion 20 covers the storage portion 9 from above. In this example, the cover portions 14 are not arranged on either outer side of the storage portion 9 in the first direction X (the width direction of the vehicle body 2) (FIGS. 2 and 3).

[0020] As shown in FIG. 1 to FIG. 6, the target wall portion 10 includes a base member 11, a cover 12 attached to the base member 11 to form a storage space S for storing a control device H between the base member 11 and the cover 12, and a bracket 5 attached to the base member 11 and disposed in the storage space S. The control device H controls the operation of the article transport vehicle 1 (traveling operation, transferring operation of the article W, etc.). In this embodiment, the target wall portion 10 is a first cover portion 14a that covers the storage portion 9 from the third direction first side Y1 (the rear side of the vehicle body 2). Therefore, the first cover portion 14a includes the base member 11, the cover 12, and the bracket 5. The target wall portion 10 further includes a bottom portion 17 that connects the lower end of the base member 11 and the lower end of the cover 12.

[0021] As shown in Figs. 3 to 5, the base member 11 is formed in a plate shape and is arranged to extend in the second direction Z (vertical direction) and the first direction X (width direction) perpendicular to the second direction Z. The base member 11 of the target wall portion 10 (here, the first cover portion 14a) is arranged to cover the storage portion 9 from the third direction first side Y1. The base member 11 is also arranged to face the surface of the article W stored in the storage portion 9 facing the third direction first side Y1. In this example, as shown in Figs. 3 to 6, the base member 11 has a step portion 15. The step portion 15 is a step portion of the base member 11 along the second direction Z (vertical direction). Due to this step portion 15, the region of the base member 11 from the step portion 15 to the first direction first side X1 is arranged on the third direction first side Y1 with respect to the region of the step portion 15 to the first direction second side X2. In the illustrated example, the base member 11 is formed in a rectangular shape when viewed in the third direction Y. The step portion 15 is formed closer to the first direction first side X1 than the center of the base member 11 in the first direction X. The upper end portion of the base member 11 is connected to the connecting portion 20. More specifically, the upper end portion of the base member 11 is fixed to the end portion of the connecting portion 20 on the third direction first side Y1.

[0022] As shown in FIG. 2, the cover 12 is disposed so as to cover the base member 11 from the third direction first side Y1. The cover 12 is configured to be detachable from the base member 11. In this example, the cover 12 is attached to both ends of the base member 11 in the first direction X and to the bottom 17 so as to be detachable. The storage space S is a space surrounded by the cover 12, the base member 11, and the bottom 17 in a state in which the cover 12 is attached. Various electrical devices and devices including the control device H can be stored in this storage space S. In the example of FIG. 2 and FIG. 6, the cover 12 is formed in a curved shape so as to bulge toward the third direction first side Y1. The bottom 17 is also formed in a curved shape so as to bulge toward the third direction first side Y1 so as to correspond to the shape of the cover 12.

[0023] As shown in FIG. 3, FIG. 4, and FIG. 6, the bracket 5 includes a plate-shaped portion 21 and an attachment portion 23 attached to the base member 11, and the plate-shaped portion 21 is disposed along the base member 11. The bracket 5 also includes a third fixing portion 26 fixed to the base member 11. In this example, the plate-shaped portion 21 is formed along the second direction Z (vertical direction) and the first direction X (width direction) in a state in which the bracket 5 is attached to the base member 11, so that the plate-shaped portion 21 is disposed parallel to a surface facing the front side (third direction first side Y1) of the base member 11. In this embodiment, the plate-shaped portion 21 is disposed so as to be spaced apart from the base member 11 on the third direction first side Y1 (the side where the cover 12 is disposed). The plate-shaped portion 21 is disposed so as to overlap the step portion 15 of the base member 11 when viewed in the third direction Y. The mounting portion 23 is a portion that is bent with respect to the plate-shaped portion 21 and attached to the base member 11. In this example, as shown in FIG. 6, the mounting portion 23 is bent from an end portion of the plate-shaped portion 21 on the first side X1 in the first direction toward the second side Y2 in the third direction (the side on which the base member 11 is disposed). Here, the mounting portion 23 is attached to the base member 11 via the third fixing portion 26. Note that the plate-shaped portion 21 does not have to be disposed parallel to the base member 11 as described above, and may be disposed in an attitude that is inclined with respect to the base member 11. Also, the plate-shaped portion 21 may be formed, for example, in a shape that bulges toward the first side Y1 in the third direction. In this way, the attitude and shape of the plate-shaped portion 21 can be changed as necessary. Note that the plate-shaped portion 21 may be a mesh-shaped member, and in this case, a configuration in which a control device or the like is attached to the mesh-shaped member can also be used. In addition, it is also possible to use the mesh portion to support one or more cables 7 on the mesh member (plate-shaped portion 21) with a cable tie or the like.

[0024] In this embodiment, as shown in FIG. 4 and FIG. 6, the third fixing portion 26 is provided at the end of the bracket 5 on the first side X1 in the first direction. The third fixing portion 26 is a portion that is bent from the mounting portion 23 and fixed to the base member 11. In this example, the third fixing portion 26 is formed by bending from the end of the mounting portion 23 on the second side Y2 in the third direction to the first side X1 in the first direction. The third fixing portion 26 is a member formed in a plate shape along a surface facing the front side (first side Y1 in the third direction) of the base member 11. The third fixing portion 26 is fixed by a fastening member in a state of abutting against the surface facing the front side of the base member 11. In the example of FIG. 4, the third fixing portion 26 is provided in a plurality of parts in the second direction Z (vertical direction). In the illustrated example, the plate-shaped portion 21, the mounting portion 23, and the third fixing portion 26 are integrally formed, but they do not necessarily have to be integrally formed.

[0025] Here, the control device H is attached to at least one of the base member 11 and the bracket 5. In this embodiment, as shown in Figs. 3 to 6, the control device H is attached to both the base member 11 and the bracket 5. The control device H also includes at least one control device. In this example, the control device H includes a plurality of control devices (in the illustrated example, the first control device H1 to the third control device H3). In this embodiment, the control devices are attached to at least one of the face (the plate-shaped part second face 21b) on the side of the base member 11 in the plate-shaped part 21 and the base member 11. Here, the first control device H1 is attached to the base member 11, and the second control device H2 and the third control device H3 are attached to the bracket 5. More specifically, the first control device H1 is fixed to an area of ​​the first direction second side X2 with respect to the step part 15 on the face of the base member 11 facing the third direction first side Y1. The first control device H1 is disposed on the second side X2 in the first direction relative to the bracket 5 (here, the plate-shaped portion 21). The second control device H2 is fixed to a surface (plate-shaped portion second surface 21b) of the plate-shaped portion 21 facing the second side Y2 in the third direction. The second control device H2 is disposed in a gap between the plate-shaped portion 21 and the base member 11 so as to be spaced apart in the third direction Y from the base member 11. The third control device H3 is fixed to a surface (plate-shaped portion first surface 21a) of the plate-shaped portion 21 facing the first side Y1 in the third direction. In this way, in this example, a plurality of control devices can be attached to each of the surface of the base member 11 facing the first side Y1 in the third direction, the plate-shaped portion first surface 21a, and the plate-shaped portion second surface 21b. The control devices include a control unit that controls the travel motor M1 and the lift motor M2 of the article transport vehicle 1, control boards of various sensors, a motor driver, a sensor driver, and the like. In addition, in this example, three control devices are arranged, but the number of control devices may be one or two, or may be three or more. Also, one control device may be fixed to both the base member 11 and the bracket 5. In the illustrated example, in addition to the third control device H3, other devices 31 different from the control devices are also fixed to the plate-shaped portion first surface 21a.

[0026] As shown in Figs. 3, 4, and 6, in this embodiment, the target wall portion 10 further includes a bridge member 6 arranged to extend along the first direction X. The bridge member 6 is arranged adjacent to the bracket 5 on the first direction second side X2, and connects an end of the bracket 5 (specifically, the plate-shaped portion 21) on the first direction second side X2 to an end of the base member 11 on the first direction second side X2. The bridge member 6 is also arranged to be spaced apart from the base member 11 in the third direction Y (Fig. 6). In this example, the bridge member 6 connects an upper end (end on one side in the second direction Z) of the plate-shaped portion 21 and an end of the first direction second side X2 to an end of the base member 11 on the first direction second side X2.

[0027] As shown in Figs. 4 and 6, the bridge member 6 includes a first fixing portion 24 fixed to the bracket 5 and a second fixing portion 25 fixed to the base member 11. The first fixing portion 24 and the second fixing portion 25 are disposed apart from each other in the first direction X. The second fixing portion 25 is disposed on the second side X2 in the first direction with respect to the first fixing portion 24. In this example, the bridge member 6 further includes a bridge main body 33, a bridge inclined portion 34, a bridge rib portion 35, and a bridge mounting portion 32. The bridge member 6 is formed in a strip shape (plate shape) that is long in the first direction X by connecting the bridge main body 33 and the bridge inclined portion 34 side by side along the first direction X.

[0028] The first fixing portion 24 is formed continuously from the end of the bridge body 33 on the first direction first side X1, and connects the end of the plate-shaped portion 21 on the first direction second side X2 to the bridge body 33. In the illustrated example, the first fixing portion 24 is bent from the end of the bridge body 33 on the first direction first side X1, and is fixed to the plate-shaped portion 21 via a fastening member. Here, the bridge body 33 is a strip-shaped member extending in the first direction X, and is arranged parallel to the surface of the base member 11 facing the third direction first side Y1. The bridge inclined portion 34 is formed continuously from the end of the bridge body 33 on the first direction second side X2. The bridge inclined portion 34 is a strip-shaped member that inclines toward the third direction second side Y2 (the side of the base member 11) as it approaches the first direction second side X2. The bridge mounting portion 32 is formed continuously from the end of the bridge inclined portion 34 on the first direction second side X2. In the illustrated example, the bridge body 33 is formed with a plurality of openings 37 penetrating in the third direction Y. Further, at the upper end of each opening 37, a plurality of first grooves 36 cut out in an arc shape are formed.

[0029] The second fixing portion 25 is formed continuously from the end of the bridge inclined portion 34 on the second side X2 in the first direction, and connects the bridge inclined portion 34 to the end of the base member 11 on the second side X2 in the first direction. In the illustrated example, the second fixing portion 25 is bent from the end of the bridge inclined portion 34 on the second side X2 in the first direction so as to follow the base member 11. The second fixing portion 25 is fixed by a fastening member in a state of abutting against a surface of the base member 11 facing the second side Y2 in the third direction. In this example, the bridge main body 33 and the bridge inclined portion 34 overlap the first control device H1 when viewed in the third direction Y, and are arranged apart from the first control device H1 in the third direction Y (FIG. 4).

[0030] The bridge rib portion 35 is bent from the upper end of the bridge body 33 toward the first side Y1 in the third direction (the side of the cover 12). The bridge rib portion 35 is formed with second groove portions 38 cut out in the up-down direction and on the first side Y1 in the third direction. In the illustrated example, the bridge rib portion 35 is formed in a plate shape that is long in the first direction X. A plurality of second groove portions 38 are formed so as to be aligned in the first direction X.

[0031] As shown in FIG. 4 to FIG. 6, when the control device H is accommodated in the accommodation space S, a wiring space E in which a part of the cable 7 accommodated in the accommodation space S is arranged is formed between the bracket 5 and the base member 11. Here, the cable 7 is connected to the control device H. The cable 7 is, for example, a communication cable or a power supply cable. In this embodiment, at least a part of the wiring space E is formed in an area surrounded by the plate-shaped part 21, the base member 11, and the control device. Note that the "enclosed area" is not limited to an area completely surrounded (covered) by such members, etc., and also includes an area that is not partially surrounded. In this example, the wiring space E is a space (gap) formed between the plate-shaped part 21 and the base member 11. In addition, the wiring space E is a space surrounded by the plate-shaped part second surface 21b, the step part 15 of the base member 11 and the surface facing the third direction first side Y1, and the first control device H1 fixed to the base member 11. Also, when the second control device H2 is attached to the plate-shaped portion second surface 21b, the wiring space E is a space formed between the second control device H2 and the base member 11. Therefore, in this case, at least a part of the wiring space E is a space surrounded by the second control device H2 in addition to the above. In the example of Fig. 5 and Fig. 6, the wiring space E can be said to be a space formed between the step portion 15 and the first control device H1. As shown in Fig. 5 and Fig. 6, the wiring space E can accommodate one or more cables 7. For example, the end of the wiring space E on the first direction second side X2 is not completely surrounded by the first control device H1 and opens in the first direction X. Therefore, in the wiring space E, the multiple cables 7 (two-dot chain line) connected in line in the second direction Z (up and down direction) in the first control device H1 can be accommodated by utilizing such an opening. When accommodating a plurality of cables 7 wired from the first control device H1, the bottom end of the wiring space E can be positioned corresponding to the bottom end of the first control device H1.

[0032] In this example, a plurality of spaces (first space F1 to fourth space F4) separate from the wiring space E are formed in the storage space S surrounded by the base member 11, the cover 12, and the bottom portion 17. As shown in Figs. 5 and 6, the first space F1 is formed between the first control device H1 and the bridge member 6. Here, the first space F1 is a space surrounded by the wiring space E and a third space F3 and a fourth space F4, which will be described later.

[0033] The second space F2 is formed between the plate-shaped portion second surface 21b and a region of the base member 11 on the first side X1 in the first direction with respect to the step portion 15. The second space F2 is a space adjacent to the wiring space E on the first side X1 in the first direction. The third space F3 is formed between the upper end of the base member 11 and the upper end of the cover 12. The third space F3 is a space above the wiring space E, the second space F2, and a fourth space F4 described later. In the example of FIG. 3 to FIG. 5, the target wall portion 10 (here, the first cover portion 14a) further includes a support plate 13. The support plate 13 is a plate-shaped member along a horizontal plane. The support plate 13 is fixed in a cantilever state to the base member 11 at a position above the bracket 5 and the first control device H1. In the illustrated example, the third space F3 is a space above the support plate 13 in the accommodation space S.

[0034] The fourth space F4 is formed on the first side Y1 in the third direction with respect to the bracket 5 and the bridge member 6 in the accommodation space S. In the illustrated example, the fourth space F4 is a space surrounded by the bracket 5, the bridge member 6, the bottom 17, and the support plate 13.

[0035] In this example, one or more cables 7 can be accommodated in the wiring space E along the second direction Z (vertical direction), and the accommodated cables 7 can be supported by the support plate 13. Specifically, a connector 43 (FIG. 5) can be arranged on the support plate 13 and connected to the wiring arranged in the third space F3. Therefore, for example, by collectively accommodating a plurality of cables 7 connected to the control boards of the control devices (here, the first control device H1 to the third control device H3) in the wiring space E and connecting each cable 7 to the corresponding connector 43 attached to the support plate 13, it is possible to easily prevent the cables 7 from interfering with the control devices and to easily prevent the plurality of wirings connected via the connectors 43 from entangling with each other. In addition, by accommodating a plurality of cables 7 in the wiring space E, it is possible to prevent these cables 7 from protruding beyond the plate-shaped portion 21 of the bracket 5 to the side of the cover 12. Furthermore, since the step portion 15 can be utilized to store the cables 7, it is easier to prevent some of the multiple cables 7 from moving over the step portion 15 into the second space F2 while the goods transport vehicle 1 is traveling, and as a result, it is less likely that these cables 7 will be arranged in a messy manner.

[0036] In addition, for example, by wiring the cable 7 connected to the third control device H3 attached to the first surface 21a of the plate-shaped portion or other devices 31 along the bridge member 6, it is possible to easily avoid the cable 7 interfering with, for example, the first control device H1 or entangling with other cables 7 connected to the first control device H1 or the second control device H2. When wiring the cable 7 to the bridge member 6, the opening 37, the first groove 36 formed in the bridge body 33, and the second groove 38 formed in the bridge rib portion 35 can be used. Specifically, when tying the cable 7 together with the bridge body 33 with a cable tie or the like while arranging the cable 7 along the bridge body 33, the cable tie can be passed through the opening 37 and hooked on the first groove 36 and the second groove 38, thereby firmly fixing the cable 7 to the bridge member 6. Therefore, it is possible to prevent the cable 7 arranged along the bridge member 6 from bending and protruding to the side of the cover 12. An end portion of the cable 7 arranged along the bridge member 6 may be arranged on the side of the support plate 13 for connection to, for example, a connector 43 attached to the support plate 13 .

[0037] Also, one or more cables 7 can be accommodated in the second space F2. For example, by accommodating in the second space F2 a type of cable 7 (such as a cable 7 connected to a different control device) different from the cable 7 accommodated in the wiring space E, the cables 7 that are less related to each other can be accommodated separately. Furthermore, since the stepped portion 15 is provided, for example, it is easy to prevent the cables 7 accommodated in the second space F2 and the wiring space E from moving and becoming entangled with each other while the article transport vehicle 1 is traveling. Also, one or more cables 7 can be accommodated in the first space F1. In this case, the bridge member 6 can prevent the cable 7 arranged in the first space F1 from jumping out beyond the bridge member 6 to the side of the cover 12. Here, in the example of FIG. 3 and FIG. 4, a connection member 27 is provided that connects the lower end of the plate-shaped portion 21 and the end on the second side X2 in the first direction to the end on the second side X2 in the first direction of the base member 11. The connection member 27 is disposed along the first direction X and parallel to the bridge member 6. The connection member 27 is also spaced apart from the first control device H1 in the third direction Y. Therefore, by using the connection member 27 as a pressing member in addition to the bridge member 6, it is possible to more effectively prevent the cable 7 accommodated in the first space F1 from jumping out beyond the bridge member 6 (and the connection member 27) to the side of the cover 12.

[0038] In addition, the third space F3 can accommodate other cables to be connected to the cable 7 wired from each control device (first control device H1 to third control device H3). In addition, these cables can be prevented from going beyond the support plate 13 and protruding into the wiring space E or the first space F1. In addition to the cables and control device H, the first space F1 to the fourth space F4 can also be used to place other necessary devices as appropriate.

[0039] As shown in Figs. 2 and 3, in this example, the second cover portion 14b is also configured to include a base member 11, a cover 12, and a bottom portion 17, similar to the first cover portion 14a (Figs. 2 and 3). Meanwhile, in this example, the second cover portion 14b is not configured as the target wall portion 10, and therefore does not include the bracket 5 or the bridge member 6 described above. However, the second cover portion 14b can also be configured as the target wall portion 10, and in this case, the second cover portion 14b can also be configured in the same manner as the first cover portion 14a described above. Also, the connecting portion 20 can be configured as the target wall portion 10. Furthermore, a plurality of target walls 10 may be arranged. For example, each of the connecting portion 20, the first cover portion 14a, and the second cover portion 14b can be configured as the target wall portion 10.

[0040] Other embodiments Next, other embodiments of the article transport vehicle 1 will be described.
