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.

A dip coating system having at least one dip-coating tank, which can be filled with a treatment fluid. A conveying system displaces the articles to the dip-coating tank, into the interior of the dip-coating tank, out of the dip-coating tank, and away therefrom. This conveying system has at least one trolley which has a fastening device for the article, which can be rotated around an axis of rotation. The trolley is drawn by at least one driven traction chain extending parallel to its movement direction. A rotating device having at least one sprocket or gear wheel that can be connected to the fastening device in a rotation-locking manner, that is arranged coaxial to the rotational axis of the fastening device, and at least one rotation chain or rotation gear rack, which extends parallel to the movement direction of the trolley, with which the sprocket or gear wheel cams.
