  • Patent number: 10056281
    Abstract: 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.

  • Patent number: 9758177
    Abstract: 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.

  • Patent number: 9583370
    Abstract: An article transport facility includes a connecting actuator device for moving an eject portion of an inactive gas supplying device relative to a support portion of a ceiling transport vehicle in order to change the positional relationship between the support portion and the eject portion between a connecting positional relationship and a separating positional relationship. The inactive gas supplying device is configured to eject the inactive gas from the eject portion with the connection between the eject portion and the container maintained after the positional relationship between the support portion and the eject portion is changed to the connecting positional relationship.
