In the case where a transport vehicle has received both a first passage permission and a second passage permission and is to pass through a second passing point, when the travel distance of the transport vehicle from a first stopping point reaches a first set distance, the transport vehicle issues, to a zone control device, a first occupation revocation request for revoking permission to occupy a first passing point, and when the travel distance of the transport vehicle from the first stopping point reaches a second set distance, the transport vehicle issues, to the zone control device, a second occupation revocation request for revoking permission to occupy the second passing point.

Article transport facility

Provided is an inspection system that can reduce the burden of inspecting a detector provided on a transport vehicle that travels on a preset transport path. An inspection systemincludes a projection surfaceF that is disposed at a position located within a detection range IE of a detectorin a state in which a transport vehicleis present at an inspection location IP set on a transport path R, and onto which detection light IL projected by the detectoris projected, an image capturing device C that captures an image of the projection surfaceF, and a determination unit that determines at least one state selected from a position, a shape, and a light intensity of the detection light IL projected onto the projection surfaceF, based on an image captured by the image capturing device C.

Inspection system

A vehicle includes one or more travel portions each configured to travel along a rail track, a travel controller configured to perform an image recognition to determine a shape of a portion of the rail track based on an image captured by an imaging device supported by the vehicle and to control the one or more travel portions based on a result of the image recognition, an information obtaining portion configured to obtain position information of each of a plurality of locations that the vehicle travels past as a result of traveling along the rail track, and to obtain the order in which the vehicle travels past such plurality of locations, and memory configured to store information obtained by the information obtaining portion.

Vehicle

Regarding a transfer system that includes a plurality of transfer vehicles that transfer articles, the present invention realizes technology that can alleviate congestion that is caused due to the travel speed of a specific vehicle that performs a specific task being lower than that of the transfer vehicles. The transfer system includes a plurality of transfer vehicles that travel on a transfer path to transfer articles, and the transfer system further includes: a specific vehicle that performs a specific task while travelling on the transfer path at a speed lower than that of the transfer vehicles; and a congestion determination unit that determines whether or not there is congestion behind the specific vehicle. Upon the congestion determination unit determining that there is congestion, the specific vehicle suspends the task and performs evacuation travel to evacuate from a task point at which the specific vehicle was performing the task.

Transfer system

A transport apparatus transports a container that includes a flow hole forming portion in which a flow hole through which gas can flow between the outside and the inside of the container is formed. A connecting portion that has a flow path through which gas can flow and a filling gas supply source that allows a filling gas to flow through the flow path are provided in the transport apparatus. The connecting portion is configured to be switchable between a non-connected state in which the connecting portion is retracted to the outside of a moving region of the container that moves along a transport path and a connected state in which the connecting portion enters the inside of the moving region and is connected to the flow hole forming portion of the container.

Container transport facility

First travel rail pair provided along a first path has a first discontinuous section. And second travel rail pair provided along a second path has a second discontinuous section. First guide members allow movement of guided members along a travel direction and restrict vertical movement of one or more of the guided member when the article transport vehicle travels through a crossing portion along the first path. Second guide members allow movement of the guided members along the travel direction and restrict vertical movement of one or more of the guided members when the article transport vehicle travels through a crossing portion along the second path.

An intermediate transfer device is located upwardly of an article delivering and receiving portion and downwardly of a ceiling transport vehicle. A transfer device grip is provided such that the intermediate transfer device is in vertical alignment with the ceiling transport vehicle and the article delivering and receiving portion and is capable of traveling, while guided and supported by a guiding support, to and among a transfer position for the delivering and receiving portion, a transfer position for the intermediate rack, a transfer-time retracted position, and a temporary-storage-time retracted. The guiding support is configured to form a space through which the grip portion and an article can pass in the vertical direction when the ceiling transport vehicle transfers the article.

Article transport facility with intermediate rack

An article transport facility in which reduction in the transport capacity can be prevented while simplifying the structure and making the facility less expensive is provided. The facility includes, as travel paths, a first travel path and a second travel path which straddles the first travel path from one side to the other side in a lateral direction of the first travel path. In a straddling portion, which is a part of the second travel path that straddles the first travel path, the second travel path is provided at a different height from the first travel path in a vertical direction, and is configured such that travel of the article transport vehicle along the first travel path and travel of the article transport vehicle along the second travel path are mutually allowed.

Article transport facility with intermediate transfer device

An article transport facility in which driving electric power can be supplied from an electricity supply line to an article transport vehicle so that it can travel through a crossing portion properly regardless of whether it is traveling along a first path or a second path. The switching device of the article transport facility is configured to switch a position change rail to a first position and a second position. The electricity supply line is supported by a first travel rail such that electric power can be supplied to the article transport vehicle traveling along the first travel rail and along the position change rail in the first position and is supported by the second travel rail such that electric power can be supplied to the article transport vehicle traveling along the second travel rail and along the position change rail in the second position.

A travel guide member which forms travel paths for an article transport vehicle is provided on a ceiling side. The travel guide member defines a plurality of travel paths along which the article transport vehicle travels in the same direction such that the travel paths are spaced apart from each other in a path lateral direction and defines a first diverging path and a second diverging path for connecting with each other a first travel path that is one of a pair of adjacent travel paths among the plurality of the travel paths and a second travel path that is the other of the pair of the adjacent travel paths. The first diverging path and the second diverging path are formed such that both extend in directions that are slanted with respect to the travel path in plan view and such that they intersect each other in plan view.
