Patent attributes
An article transport facility comprises storage sections, a transport device, a controller, and a learning module. The transport device has a transfer device having a support portion, and a light-emitter-receiver. The controller is caused to store information that indicates a second target position at which the transfer device is located when transferring an article, and information that indicates a first target position to which the support portion is moved. Each of a plurality of storage sections is provided with a reflector. A learning control performed by the controller is a control in which a first target position and a second target position are learned based on information of an image of the reflector captured by the imaging device of the learning module and pre-learning position information. Each reflector has a first area which forms the periphery of the reflector, and a second area in the first area. The relationship between the reflectance and the wave length of the reflected light is different between the first area and the second area.
