The cleaning space 10C communicates with the clean area so that the air in the clean space 10C does not flow into the clean area.

If the conveyed material cannot be cleaned even by cleaning the cleaning space 10C with the cleaning device 13 (when the amount of contaminants detected by the contaminant detection means 16 is equal to or more than a specified value), the cleaning device 13 If the amount of contaminants is still higher than the specified value after re-cleaning,
The control device 40 is configured to reversely rotate the transport rotator 20 and return the transport rotator 20 to the contaminated area as shown in FIG. 7 which is a conceptual diagram. At this time, since the transport rotator 20 is returned by two sections, the section corresponding to the storage opening 10A returns to the area (washing space 10G) symmetrically located with the washing space 10C, and the area is contaminated. If such a situation is repeated, the section contaminated in the area may reach the carry-out opening, and contaminants may leak into the clean space.
Since this area is the cleaning space 10G, this can be avoided by cleaning the corresponding section. In addition, by using the cleaning space 10G, it is possible to rotate the transport rotator 20 in the direction opposite to the above-described direction and carry out the article.

In the above configuration example, the transport rotary body is configured to rotate on a vertical rotary shaft, but is not limited to this, and may be configured to rotate on a horizontal rotary axis. is there.

[0031]

As described above, according to the article unloading apparatus of the present invention, articles are continuously unloaded from the contaminated area to the clean area without being contaminated by the rotation of the transport rotating body. It is possible to carry out extremely rational transport.

Further, based on the detection information from the detection means provided in the cleaning area, the control device reverses the transport rotating body when the contaminated state of the conveyed material after cleaning in the cleaning area is equal to or more than a specified value, and the conveyed material is reversed. Is returned to the contaminated area open position, so that contaminated articles that have been insufficiently cleaned and contaminated can be prevented from being transported to the clean area.
