Abstract: An article transport facility includes an article transport vehicle, a storage rack configured to store articles, and a for-rack transport device. The article transport vehicle is configured to travel along one or more rails suspended from, and supported by, a ceiling. The storage rack is suspended from, and supported by, the ceiling. The for-rack transport device is located on an opposite side from the one or more rails with respect to the storage rack.

Abstract: A rail inspection device comprises a carriage having wheels, a first roller in contact with a side surface of a first rail, a second roller in contact with a side surface of a second rail, a first position sensor configured to detect a position of a side surface of the first rail or an outer surface of the first roller, a second position sensor configured to detect a position of a side surface of the second rail or an outer surface of the second roller, and at least one rotation sensor each configured to detect a rotation angle of a wheel, the first roller, or the second roller.

Abstract: An article transport facility includes a transport device which has a connecting portion connected to the storage device, and which is configured to transport an article. The connecting portion is located on the first side with respect to the first path whereas a subject path is located on the second side with respect to the first path. The transporting path of an article by the transport device is so located to cross the first path in plan view and to extend at least from the connecting portion and to the second side with respect to the first path. A first transfer portion to or from which an article is transferred by a transport vehicle traveling along the subject path is set in a portion of the transporting path that is located on the second side with respect to the first path.

Abstract: An article transport facility includes an article transport vehicle which is suspended from and supported by one or more travel rails supported by a ceiling, and is configured to suspend and support an article, and to transport the article from a support platform that serves as a transport origin to another support platform that serves as a transport destination. This article transport facility has an adjusting-purpose support platform which includes an adjusting-purpose support surface on which an adjusting-purpose device, which is used for a purpose of adjusting transporting-purpose profile information, can be placed in the same manner in which an article is placed on a support platform. The adjusting-purpose support surface is capable of being moved such that a height thereof can be varied continuously between an upper limit height and a lower limit height specified in advance.

Abstract: An article transport facility is provided with a first control device that controls an article transport vehicle in a first area in which articles are transported, and a second control device that controls the article transport vehicle in a second area in which adjustment of the article transport vehicle is performed. Based on a withdrawal instruction from the first control device, an operation control portion of an article transport vehicle that needs adjustment causes the article transport vehicle to enter the second area, and a communication control portion that can perform exclusive wireless communication with the first control device and the second control device changes the communication destination to the second control device.

Abstract: A transport device is configured to transport different kinds of articles which have different lengths from the held portion or a position corresponding to the held portion to one end portion along the fore and aft direction. There are provided an article detection device for detecting an article, end detection device for detecting the one end portion, along the fore and aft direction, of the article detected by the article detecting device, and a determination device for determining the kind of the article based on detected information from the article detecting device and detected information from the end detection device.
