In this way, while returning to the original position, the pressing piece 5 provided on the lower side of one end of the transport frame 4
comes into contact with the article that is inverted at the _Z1 position, but due to this contact, the pressing piece 5 moves in the direction of the arrow E with the support shaft 5a as a fulcrum.
Since the transport frame 4 can swing in the direction, the transport frame 4 can be moved over the article A existing at the _Z1 position, and the return of the transport frame 4 can be ensured.

Hereafter, the above operation is repeated. Therefore, X
Article A transported from position to Y position in an upright state
This is possible when the article A is subjected to a prescribed work that is possible while standing upright at the Y position, and is in an inverted state after being conveyed inverted and is inverted at the _Z1 position. A prescribed work is performed.

In the above embodiment, the article mounting table 2 is placed at the X position.
However, the present invention is not limited to this arrangement; for example, the article A may be held in a hanging bucket. Moreover, if the pressing piece 5 is changed, the article A
may be conveyed in the opposite direction to that in this embodiment.

As explained above, although this invention allows articles to be continuously reversed and conveyed at a predetermined pitch, the operating means that is the power source for reverse conveyance is entrusted to a single cylinder. Because of this, it has advantages such as simple structure, proper operation, and improved workability.
