A size of a conveyance device is reduced. A conveyance device includes: a carriage configured to travel along a track; and a transfer mechanism hung from the carriage so as to be capable of being raised and lowered. The transfer mechanism includes a plurality of chucks each of which is configured to revolve about a rotation center provided in the transfer mechanism.

Conveyance device

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

An article transport facility comprises a travel rail installed along a travel path, and a travel vehicle which is guided along the travel path with a travel wheel rolling on a travel surface of the travel rail. The travel vehicle has a distance measuring device for measuring a distance to the travel surface. And the distance measuring device includes a pair of distance sensors spaced apart from each other along a travel direction of the travel vehicle.
