Description

[Technical Field]

[0001] The present invention relates to a mobile body cleaning system for cleaning a mobile body. [Background technology]

[0002] Conventionally, in article transport facilities that transport articles using moving bodies such as transport vehicles, the transport vehicles are periodically cleaned. For example, in the facility disclosed in JP 2013-184762 A (Patent Document 1), the transport vehicles (3) are cleaned by a cleaning device installed at the end of the travel path of the transport vehicles (3). This cleaning is performed by removing dust adhering to the transport vehicles (3) with air sprayed from a nozzle (20). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-184762 Summary of the Invention [Problem to be solved by the invention]

[0004] One of the causes of dust adhesion to a moving object is static electricity. When dust adheres to a moving object due to static electricity, it takes a certain amount of time to remove the dust by spraying air from a nozzle alone. For this reason, conventional cleaning devices perform cleaning while the moving object is stopped. However, when using such a cleaning device, idle time occurs due to stopping the moving object, which can reduce the operating rate of the moving object.

[0005] In view of the above circumstances, it is desirable to realize a mobile body cleaning system that can properly remove dust adhering to a mobile body and can suppress a decrease in the operating rate of the mobile body. [Means for solving the problem]

[0006] A mobile body cleaning system for cleaning a mobile body, a cleaning device disposed in a specific section set on a movement path of the moving body; The cleaning device is a cover disposed so as to surround a movement trajectory of the moving object passing through the specific section at a position that does not interfere with the movement trajectory; a static eliminator that is disposed in a position that does not interfere with the movement path in the space within the cover and that removes static electricity from the moving body; a dust removal device that is disposed in a position that does not interfere with the movement path in the space within the cover and removes dust adhering to the moving body; Equipped with The static eliminator and the dust remover are activated at least while the moving body is moving through the specific section.

[0007] According to this configuration, dust adhering to a moving body can be removed while removing static electricity while the moving body is moving. Therefore, dust adhering to the moving body can be efficiently removed. Furthermore, since dust adhering to the moving body can be properly removed and the cover placed in the specific section is configured not to interfere with the movement trajectory of the moving body passing through the specific section, the moving body does not have to be stopped when removing dust. Therefore, the operating rate of the moving body can be prevented from decreasing. As described above, according to this configuration, dust adhering to a moving body can be properly removed and a decrease in the operating rate of the moving body can be suppressed.

[0008] Further features and advantages of the techniques according to the present disclosure will become more apparent from the following description of exemplary and non-limiting embodiments, which proceeds with reference to the drawings. [Brief explanation of the drawings]

[0009] [Figure 1] Plan view of a transport facility equipped with a mobile cleaning system [Figure 2] Perspective view of a moving object [Figure 3] Side view of cleaning device [Figure 4]Front view of the cleaning device [Figure 5] Mobile cleaning system configuration diagram DETAILED DESCRIPTION OF THE INVENTION

[0010] A mobile body cleaning system is a system for cleaning a mobile body. The mobile body cleaning system can be used, for example, in an article transport facility that transports articles. Below, an embodiment of the mobile body cleaning system will be described, taking as an example a case where the mobile body cleaning system is applied to an article transport facility.

[0011] As shown in FIG. 1, the article conveying facility F is provided with a movement path 9 for a moving body 1. The moving body 1 is configured to move along the movement path 9. In this embodiment, the moving body 1 is configured as a transport vehicle that transports an article (not shown). The movement path 9 is configured using rails 90 installed along the extension direction of the movement path 9 (see also FIG. 2). In this example, the rails 90 are installed near the ceiling. The moving body 1 that moves along these rails 90 is configured as a so-called ceiling transport vehicle.

[0012] Various items are handled by the item transport facility F. In this example, the item transport facility F is used in a semiconductor manufacturing factory. Therefore, the items include substrate containers (so-called FOUPs: Front Opening Unified Pods) that store substrates (wafers, panels, etc.) and reticle containers (so-called reticle pods) that store reticles. In this case, the movable body 1 transports items such as substrate containers and reticle containers between processes along the movement path 9.

[0013] In this embodiment, the item transport equipment F has a plurality of bays 7. A plurality of transfer target locations 8 are provided in each bay 7. The transfer target locations 8 are locations to which items are to be transferred. In other words, the transfer of items is carried out by the moving body 1 at the transfer target locations 8. In this example, the movement path 9 includes an intra-bay path 91 provided in each bay 7 and an inter-bay path 92 connecting the plurality of bays 7.

[0014] In this embodiment, the transfer target location 8 includes a processing device 80 that processes the article, and a mounting table 81 that is arranged adjacent to the processing device 80. "Processing the article" refers to processing of the object (substrate or reticle) contained in the article serving as a container. The mobile body 1 receives from the mounting table 81 an article that has been processed by the processing device 80, or delivers to the mounting table 81 an article that has not yet been processed by the processing device 80. The processing device 80 performs various processes, such as thin film formation, photolithography, and etching.

[0015] The article transport facility F includes a plurality of moving bodies 1 and a host control device Ct (see FIG. 5) that manages the plurality of moving bodies 1. Each of the plurality of moving bodies 1 is configured to receive a transport command from the host control device Ct and execute a task according to the transport command. For example, the transport command includes information on the origin and destination of the article. Upon receiving the transport command, the moving body 1 transports the article from the origin to the destination. The origin and destination include the transfer target location 8 described above.

[0016] As shown in FIG. 2, in this embodiment, the moving body 1 includes a traveling unit 10 having wheels 101 that roll on rails 90, and a vehicle body 11 that is suspended and supported by the traveling unit 10.

[0017] The traveling unit 10 includes a motor 102. The wheels 101 are configured to rotate when driven by the motor 102. Although detailed illustration is omitted, in this example, a power supply line is arranged along the rail 90, and the traveling unit 10 is configured to obtain power by receiving power from the power supply line in a non-contact manner. In the example shown, the moving body 1 further includes an upper guide roller 103 used to change the direction of travel, and a lower guide roller 104 for stabilizing the posture during movement. The wheels 101 and the lower guide roller 104 roll on the rail 90 as the moving body 1 moves. The upper guide roller 103 rolls on a guide rail (not shown) as the moving body 1 moves.

[0018] Here, dust can be generated due to wear of the wheels 101, the upper guide rollers 103, the lower guide rollers 104, etc. Some of the generated dust may adhere to the moving body 1, so the moving body 1 needs to be cleaned periodically. In particular, in facilities that require a clean environment, such as semiconductor manufacturing plants, the allowable amount of dust (particles) that can be present per cubic meter is determined by ISO standards and the like, and cleaning of the moving body 1 is highly necessary. Furthermore, the inventors' diligent research has revealed that dust adheres to the moving body 1 due to static electricity.

[0019] 1, a mobile body cleaning system 100 according to the present disclosure includes a cleaning device 2 arranged in a specific section S set on a moving path 9 of a mobile body 1. By arranging the cleaning device 2 in the specific section S of the moving path 9, the mobile body 1 passing through the specific section S can be cleaned in a relatively short time span. This will be described in detail below.

[0020] 3 and 4 show the cleaning device 2. In this specification, the direction along the movement path 9 is defined as the movement direction D, one side of the movement direction D is defined as the movement direction first side D1, and the other side of the movement direction D is defined as the movement direction second side D2. Here, the moving body 1 is configured to move from the movement direction first side D1 toward the movement direction second side D2.

[0021] As shown in FIGS. 3 and 4, the cleaning device 2 includes a cover 20 disposed so as to surround the movement trajectory T1 of the moving object 1 passing through the specific section S at a position that does not interfere with the movement trajectory T1.

[0022] The cover 20 is arranged so as to cover at least both sides of the movement trajectory T1 of the moving body 1 (both left and right sides based on the traveling direction of the moving body 1). In this embodiment, the cover 20 is arranged so as to cover both sides and below the movement trajectory T1 of the moving body 1. An internal cover space Is is formed in the space covered by the cover 20, and an external space Es is formed outside the cover 20. In other words, the cover 20 separates the internal cover space Is from the external space Es.

[0023] A first opening 201 is provided at an end of the cover 20 on the first side D1 in the movement direction. A second opening 202 is provided at an end of the cover 20 on the second side D2 in the movement direction. The moving body 1 is configured to enter the space within the cover Is through the first opening 201 and exit the space within the cover Is through the second opening 202. In other words, the moving body 1 is configured to pass through the space within the cover Is by moving through the specific section S from the first side D1 in the movement direction toward the second side D2 in the movement direction. In this example, the first opening 201 and the second opening 202 are always open.

[0024] The cleaning device 2 includes a static eliminator 21 that removes static electricity from the moving object 1, and a dust remover 22 that removes dust adhering to the moving object 1. The static eliminator 21 and the dust remover 22 are configured to operate at least while the moving object 1 is moving through the specific section S. In this embodiment, a cleaning control unit C2, which will be described later, operates the static eliminator 21 and the dust remover 22 while the moving object 1 is moving through the specific section S, based on the recognition result by the moving object recognition unit 3 (see FIG. 5). This makes it possible to remove dust adhering to the moving object 1 while removing static electricity from the moving object 1. This makes it possible to efficiently remove dust adhering to the moving object 1.

[0025] Furthermore, the static eliminator 21 and the dust remover 22 are disposed at positions that do not interfere with the movement trajectory T1 in the in-cover space Is covered by the cover 20. This prevents the static eliminator 21 and the dust remover 22 from coming into contact with the moving body 1 moving in the in-cover space Is. Therefore, the moving body 1 can pass through the in-cover space Is smoothly without stopping.

[0026] In this embodiment, the dust removal device 22 is configured to inject air from above onto the vehicle body 11 of the movable body 1. As described above, the movable body 1 according to this embodiment is an overhead transport vehicle, and dust is likely to be generated from the traveling units 10 arranged above the rails 90. Therefore, dust generated in the traveling units 10 is likely to adhere to the vehicle body 11, which is suspended and supported below the rails 90. However, with the above configuration, the dust removal device 22 injects air from above onto the vehicle body 11 of the movable body 1, thereby efficiently removing dust that has adhered to the vehicle body 11 from above.

[0027] In this embodiment, an air injection type ionizer IN is provided that injects air containing ions toward the movement trajectory T1 in the space Is within the cover. The ionizer IN serves as both the static eliminator 21 and the dust removal device 22. By using the ionizer IN as a single device for the static eliminator 21 and the dust removal device 22, it is easier to achieve a reduction in size of the entire cleaning device 2 than by using the static eliminator 21 and the dust removal device 22 separately. Note that various types of ionizer IN can be used, such as a corona discharge type, a soft X-ray type, a radiation type, or an ultraviolet type.

[0028] In this embodiment, the specific section S includes a processing section Sp, which is a section where the static eliminator 21 and the dust removal device 22 are arranged, and a buffer section Sb, which is not arranged with the static eliminator 21 or the dust removal device 22. Thus, the specific section S where the cover 20 is arranged includes two types of sections: the processing section Sp and the buffer section Sb. Although the cover 20 is configured to include these two types of sections, it is arranged continuously throughout the entire specific section S in the movement direction D.

[0029] The buffer section Sb includes at least one of a first buffer section Sb1 disposed on a first side D1 in the movement direction relative to the processing section Sp and a second buffer section Sb2 disposed on a second side D2 in the movement direction relative to the processing section Sp. In this embodiment, the buffer section Sb includes both the first buffer section Sb1 and the second buffer section Sb2. That is, in this embodiment, the processing section Sp, where dust removal is performed, is sandwiched between the first buffer section Sb1 and the second buffer section Sb2 in the movement direction D. With this configuration, dust scattered during the removal work in the processing section Sp will not scatter from the first opening 201 or the second opening 202 into the external space Es unless it passes through the first buffer section Sb1 or the second buffer section Sb2. That is, the first buffer section Sb1 and the second buffer section Sb2 function as barriers to prevent dust from leaking from the internal space Is to the external space Es.

[0030] The buffer section Sb is provided with an exhaust device 23 that forms an air flow from the cover interior space Is toward the external space Es outside the cover 20, and a filter 24 that adsorbs dust contained in the air exhausted by the exhaust device 23 from the cover interior space Is to the external space Es. This allows dust removed from the moving body 1 to be captured in the cover interior space Is to prevent it from scattering into the external space Es. Clean air from which dust has been removed is exhausted to the external space Es. The exhaust device 23 is configured using, for example, a fan. However, the exhaust device 23 may also be configured using a negative pressure device or the like.

[0031] In this embodiment, a fan filter unit FFU, in which the exhaust device 23 and the filter 24 are integrated, is provided in the buffer section Sb. In the example shown in the figure, a fan filter unit FFU is provided in all of the buffer sections Sb. That is, a fan filter unit FFU is provided in each of the first buffer section Sb1 and the second buffer section Sb2.

[0032] Furthermore, in this embodiment, an exhaust device 23 that forms an air flow from the cover intra-space Is to the external space Es outside the cover 20 is attached to the bottom 203 of the cover 20 that covers the movement trajectory T1 of the movable body 1 from below. Dust contained in the air exhausted from the cover intra-space Is to the external space Es by the exhaust device 23 is adsorbed by the filter 24. In this example, a fan filter unit FFU, in which the exhaust device 23 and the filter 24 are integrated, is provided on the bottom 203 of the cover 20. With the above-mentioned configuration, a downward air current can be generated in the cover intra-space Is, and dust that has fallen to the bottom by the air jet from the dust removal device 22 can be efficiently sucked in and captured by the filter 24.

[0033] As described above, the moving object 1 is configured to enter the in-cover space Is through the first opening 201 and exit the in-cover space Is through the second opening 202. Therefore, when the moving object 1 exits the in-cover space Is through the second opening 202, an airflow is generated from the second opening 202 toward the external space Es, and dust may be carried by the airflow and scattered into the external space Es.

[0034] Therefore, in this embodiment, an air curtain 202a that restricts the flow of air in the movement direction D that passes through the second opening 202 is provided at the second opening 202, which serves as an exit for the moving object 1. As described above, the "flow of air in the movement direction D that passes through the second opening 202" refers to the airflow that flows from the second opening 202 toward the external space Es. With this configuration, when the moving object 1 exits from the internal space Is of the cover, it is possible to prevent dust removed in the internal space Is from moving together with the moving object 1 and scattering from the second opening 202 into the external space Es.

[0035] As described above, the mobile body cleaning system 100 according to the present disclosure makes it possible to clean the mobile body 1 without stopping the mobile body 1. Therefore, while the mobile body 1 is cleaning, the movement of other mobile bodies 1 is not restricted. Therefore, the location where the specific section S is set, in other words, the location where the cleaning device 2 is installed, may be anywhere on the travel route 9.

[0036] Preferably, the specific section S is set in a section of the moving path 9 where the number of moving objects 1 passing through per unit time is equal to or greater than a predetermined threshold. This can relatively increase the frequency at which the moving objects 1 pass through the specific section S, thereby increasing the frequency at which the moving objects 1 are cleaned. This makes it easier to achieve a cleaner environment. In the example shown in FIG. 1 , the specific section S is set in the inter-bay path 92, which the moving objects 1 pass through more frequently than the intra-bay path 91. As shown in the figure, the specific section S may be set at multiple locations on the moving path 9. This can further increase the frequency at which the moving objects 1 are cleaned. Furthermore, from the perspective of the frequency at which the moving objects 1 pass through, when the moving path 9 includes both straight and curved paths, it is preferable to set the specific section S in a straight path, which is likely to result in a higher moving speed and a higher frequency of passing through. Furthermore, the specific section S may be set in an area where a temporary storage area for temporarily storing items is provided near the moving path 9. This is because the frequency at which the moving objects 1 pass through such areas is also relatively high.

[0037] FIG. 5 shows a system configuration diagram of the mobile cleaning system 100.

[0038] 5, the mobile body cleaning system 100 includes a host control device Ct that manages multiple mobile bodies 1 present in an article transport facility F, and a cleaning device 2. In this example, the host control device Ct and the mobile bodies 1 are configured to be able to communicate with each other. The host control device Ct and the cleaning device 2 are also configured to be able to communicate with each other.

[0039] The cleaning device 2 includes a cleaning control unit C2 that controls each functional unit of the cleaning device 2. In this embodiment, the cleaning control unit C2 is configured to control the ionizer IN and the fan filter unit FFU.

[0040] In this embodiment, the moving body cleaning system 100 includes a moving body recognition unit 3 that recognizes a moving body 1 entering a specific section S. In this example, the moving body recognition unit 3 is a component of the cleaning device 2. The moving body recognition unit 3 is configured using a sensor (e.g., an optical sensor) that detects the moving body 1. In this example, the moving body recognition unit 3 is configured to recognize the moving body 1 before it enters the specific section S. Therefore, for example, the sensor configured as the moving body recognition unit 3 may be arranged on the first side D1 in the movement direction relative to the specific section S.

[0041] In this embodiment, the operation of the static eliminator 21 and the dust removal device 22 is started based on the recognition of the moving object 1 by the moving object recognition unit 3. That is, the cleaning control unit C2 starts the operation of the static eliminator 21 and the dust removal device 22 (ionizer IN in this example) when the moving object recognition unit 3 recognizes the moving object 1. The start of the operation of the static eliminator 21 and the dust removal device 22 may be performed simultaneously with the recognition of the moving object 1 by the moving object recognition unit 3, or may be performed after the recognition by the moving object recognition unit 3. In either case, it is preferable that the operation of the static eliminator 21 and the dust removal device 22 be started at a timing before the moving object 1 enters the specific section S.

[0042] In this embodiment, the operation of the static eliminator 21 and the dust removal device 22 is terminated based on the recognition of the moving object 1 by the moving object recognition unit 3. That is, the cleaning control unit C2 terminates the operation of the static eliminator 21 and the dust removal device 22 (the ionizer IN in this example) when the moving object recognition unit 3 recognizes the moving object 1. In this example, the cleaning control unit C2 terminates the operation of the static eliminator 21 and the dust removal device 22 after a predetermined set period has elapsed since the moving object recognition unit 3 recognized the moving object 1. This set period may be determined based on the time required for the moving object 1 to exit the in-cover space Is.

[0043] With the above configuration, the de-ionization device 21 and the dust removal device 22 can be operated in accordance with the entry of the moving body 1 into the specific section S, thereby improving the energy efficiency of the moving body cleaning system 100 compared to when these devices are operated continuously regardless of the entry of the moving body 1.

[0044] On the other hand, there may be a large time lag between when the exhaust device 23 starts operating and when it reaches an output that actually performs the exhaust function. Also, the power consumption of the exhaust device 23 during operation is generally lower than that of the ionizer IN. For these reasons, in this embodiment, the exhaust device 23 is operated continuously. The exhaust device 23 is operated for at least a period of time longer than the operation time of the ionizer IN. For example, it is possible to keep the exhaust device 23 operating at all times while the article conveying equipment F is in operation.

[0045] Other Embodiments Next, other embodiments will be described.

[0046] (1) In the above embodiment, an example has been described in which the cover 20 is arranged to cover both sides and below the movement trajectory T1 of the moving body 1. However, without being limited to this example, the area that the cover 20 covers along the movement trajectory T1 of the moving body 1 can be changed as appropriate depending on the type of the moving body 1. For example, if the moving body 1 is an AGV that travels on a floor, there is a floor, so the cover 20 does not need to cover below the movement trajectory T1 of the moving body 1. On the other hand, it is preferable that the cover 20 cover above the movement trajectory T1 of the moving body 1 (AGV).

[0047] (2) In the above embodiment, an example has been described in which the first opening 201 and the second opening 202 are always open. However, the present invention is not limited to such an example, and an automatic door may be provided at one or both of the first opening 201 and the second opening 202, and may be configured to open when the moving object 1 passes through the specific section S.

[0048] (3) In the above embodiment, an example has been described in which the moving object recognition unit 3 is configured using a sensor. However, without being limited to such an example, the moving object recognition unit 3 may be configured as a software functional unit. In this case, for example, the moving object recognition unit 3 may be configured to recognize the moving object 1 by acquiring current position information of the moving object 1 on the movement route 9 from the upper control device Ct. Note that, as another example in which the moving object recognition unit 3 is configured as a software functional unit, the moving object recognition unit 3 may be a component of the upper control device Ct rather than a component of the cleaning device 2.

[0049] (4) In the above embodiment, an example has been described in which the exhaust device 23 and the filter 24 are integrated to form the fan filter unit FFU. However, the present invention is not limited to this example, and the exhaust device 23 and the filter 24 may be provided independently. In this case, a common filter 24 may be provided for multiple exhaust devices 23. In this case, for example, multiple pipes through which air discharged by the multiple exhaust devices 23 passes may be provided, and the filter 24 may be provided in a confluence path where the multiple pipes join together.

[0050] (5) In the above embodiment, an example has been described in which the moving body 1 is configured as a so-called overhead transport vehicle. However, the moving body 1 is not limited to such an example, and may be an AMR (Autonomous Mobile Robot), an AGV (Automatic Guide Vehicle), a tracked vehicle, a drone, or the like.

[0051] (6) The configurations disclosed in the above-described embodiments may be combined with configurations disclosed in other embodiments as long as no contradictions arise. Regarding other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications may be made as appropriate within the scope of the present disclosure.

[0052] [Summary of this embodiment] The summary of this embodiment will be described below.

[0053] A mobile body cleaning system for cleaning a mobile body, a cleaning device disposed in a specific section set on a movement path of the moving body; The cleaning device is a cover disposed so as to surround a movement trajectory of the moving object passing through the specific section at a position that does not interfere with the movement trajectory; a static eliminator that is disposed in a position that does not interfere with the movement path in the space within the cover and that removes static electricity from the moving body; a dust removal device that is disposed in a position that does not interfere with the movement path in the space within the cover and removes dust adhering to the moving body; Equipped with The static eliminator and the dust remover are activated at least while the moving body is moving through the specific section.

[0054] According to this configuration, dust adhering to a moving body can be removed while removing static electricity while the moving body is moving. Therefore, dust adhering to the moving body can be efficiently removed. Furthermore, since dust adhering to the moving body can be properly removed and the cover placed in the specific section is configured not to interfere with the movement trajectory of the moving body passing through the specific section, the moving body does not have to be stopped when removing dust. Therefore, the operating rate of the moving body can be prevented from decreasing. As described above, according to this configuration, dust adhering to a moving body can be properly removed and a decrease in the operating rate of the moving body can be suppressed.

[0055] A direction along the movement path is defined as a movement direction, one side of the movement direction is defined as a movement direction first side, and the other side of the movement direction is defined as a movement direction second side, the specific section includes a processing section in which the static eliminator and the dust removal device are disposed, and a buffer section in which the static eliminator and the dust removal device are not disposed, the buffer section includes at least one of a first buffer section arranged on a first side of the processing section in the movement direction and a second buffer section arranged on a second side of the processing section in the movement direction, Preferably, the cover is disposed continuously over the entire specific section in the moving direction.

[0056] According to this configuration, the buffer section allows the distance between the end of the cover and the processing section in the direction of movement to be increased. The cover is also continuously disposed throughout the specific section, including the processing section and the buffer section. This makes it easier to prevent dust from scattering outside the cover.

[0057] The buffer section includes: an exhaust device that forms an air flow from the space inside the cover toward an external space outside the cover; a filter that absorbs dust contained in the air exhausted from the cover interior space to the exterior space by the exhaust device; It is preferable that the following is provided.

[0058] According to this configuration, dust removed from the moving body can be captured in the space inside the cover so that it does not scatter into the external space outside the cover.

[0059] an air injection type ionizer that injects air containing ions toward the movement trajectory in the space within the cover; Preferably, the ionizer serves as both the static eliminator and the dust remover.

[0060] With this configuration, the air injection ionizer can simultaneously remove static electricity from the moving object and remove dust adhering to the moving object. This reduces the installation space for the static eliminator and dust remover, making it easier to downsize the cleaning device and perform efficient cleaning.

[0061] a moving object recognition unit that recognizes the moving object entering the specific section, It is preferable that the static eliminator and the dust removing device start operating based on the recognition of the moving object by the moving object recognition unit.

[0062] According to this configuration, the de-ionization device and dust removal device can be operated in accordance with the entry of a moving object into a specific section, thereby improving the energy efficiency of the moving object cleaning system compared to when these devices are operated continuously regardless of the entry of the moving object.

[0063] It is preferable that the specific section be set to a section on the travel route where the number of passing mobile objects per unit time is equal to or greater than a predetermined threshold value.

[0064] According to this configuration, the number of times the moving body passes through the specific section can be increased, which increases the frequency with which the moving body is cleaned, and ultimately makes it easier to keep the moving body clean.

[0065] the movement path is configured using rails installed along an extension direction of the movement path, the moving body comprises a traveling unit having wheels that roll on the rails, and a vehicle body suspended and supported by the traveling unit; the dust removal device is configured to inject air onto the vehicle body from above, an exhaust device that forms an air flow from the space inside the cover to an external space outside the cover is attached to a bottom portion of the cover that covers the movement locus from below, It is preferable that the exhaust device is configured so that dust contained in the air exhausted from the space within the cover to the external space is adsorbed by a filter.

[0066] In this configuration, due to the relative positioning of the wheels and the vehicle body, dust generated by wheel wear is likely to adhere to the vehicle body. However, with this configuration, the dust removal device injects air onto the vehicle body from above, so dust adhering to the vehicle body can be efficiently removed. Furthermore, with this configuration, an exhaust device is attached to the bottom of the cover, so a downward air current can be generated in the space within the cover, and dust that falls to the bottom due to the air injection from the dust removal device can be efficiently sucked in and absorbed by the filter. Therefore, the amount of dust removed from the vehicle that scatters outside the space within the cover can be reduced. [Industrial Applicability]

[0067] The technology according to the present disclosure can be used in a mobile body cleaning system that cleans a mobile body. [Explanation of symbols]
