According to the present invention, there is provided an apparatus for transferring / returning a moving tank, which comprises an air-floating cart loaded with a moving tank mounted with the moving tank, via a turntable, a carriage moving / retracting means, and an angle opening / closing means. It can freely turn and move around a turntable to a target station among a large number of stations arranged on its outer circumference with a minimum space with a small force, and Since all operations are completed in the same tank, there is no need to worry about contamination, etc., as a whole, the equipment is lighter and the equipment is compact, so investment costs are reduced, and more stations can be easily installed. It is also possible to increase production.
In addition, as mentioned above, the space for the air-floating trolley to turn and move is minimal, so it greatly contributes to the effective use of factory land, and further, changes in product brands, increases and decreases in production volume, etc. Can quickly follow, so that it can sufficiently cope with multi-variable production that is expected in the future.
