A conveying apparatus that increases the conveying speed of a conveyance object, and improves reliability and conveyance efficiency at low cost. Acceleration/deceleration sections, each of which includes a plurality of variable-speed conveyance sections, are provided among constant-speed conveyance sections. The conveying speed of a conveyance object is continuously accelerated or decelerated while the conveyance object passes through the acceleration/deceleration sections. This changes the conveying speed from the conveying speed of the upstream constant-speed conveyance section to the conveying speed of the downstream constant-speed conveyance section. Thus, it is controlled that the conveying speed and the conveyance acceleration/deceleration is identical between the upstream conveyance section and the downstream conveyance section when the conveyance object is transferred from the upstream conveyance section to the downstream conveyance section.

A storage facility for semiconductor containers is provided. The storage structure has partitioning walls including a side wall portion extending along a vertical direction, and holding space partitioned off from exterior space by the partitioning walls. Inactive gas enriched air, which contains higher concentration of inactive gas than concentration of inactive gas contained in air in the exterior space, is supplied to the holding space. And a first opening for allowing containers being carried into and out of the storage structure to be moved through the side wall portion is formed in the side wall portion. A first inlet opening is located at a position which is in the exterior space and is adjacent an edge of the first opening. And a first drawing-in device is provided in the storage structure to discharge air drawn in through the first inlet opening into discharge space which is outside the holding space and is divided off from the exterior space.

A sub-path is connected to a first main path and a second main path along which an article transport vehicle travels in a direction opposite to that of the first main path. The sub-path includes an intersection portion, a first upstream path connected to the first main path and the intersection portion, a second upstream path connected to the second main path and the intersection portion, a first downstream path connected to the intersection portion and the second main path, and a second downstream path connected to the intersection portion and the first main path. In the intersection portion, a first connection path that connects the first upstream path and the first downstream path, and a second connection path that connects the second upstream path and the second downstream path are provided so as to be located at the same height and to intersect each other.

An article transport facility includes an engaging member capable of being moved to an engaging position at which the engaging member is in engagement with a movable guide portion and with a fixed guide portion to hold the movable guide portion in the guiding position, and to a releasing position at which the engaging member is not in engagement with at least one of the movable guide portion and the fixed guide portion wherein the engaging member supports the movable guide portion from below when in the engaging position; an urging member for urging the engaging member; a holding device for generating an operating force with electric power supplied from an electric power supply to hold the engaging member in the engaging position against an urging force of the urging member; and a power-supply controller for controlling the operation of the electric power supply. The power-supply controller maintains electric power supply in an electric power supplying state while fire information is not outputted from a fire detector and switches the electric power supply to an electric power non-supplying state if fire information is outputted from the fire detector.

A conveying-traveling-body-utilizing conveying device links conveying traveling bodies to each other where load bars are continuous to each other. A linked part is provided at one end of the load bar, and a linking hook is provided at the other end which can engage with and disengage from the linked part. The linking hook is pivotally supported and is vertically movable between a pre-engagement orientation separated upward from the linked part, with respect to an engaged orientation of covering the linked part from above, and a standby orientation tilted to a lowering limit from the engaged orientation by an urging force. When the linking hook is in the standby orientation, longitudinally adjacent conveying traveling bodies can approach each other to a connected state, where the respective load bars are abutted against each other, without the linking hook in the standby orientation and the linked part contacting each other.

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.
