Then, the drive motor 823 is rotated forward to rotate both the rotating shafts 810 by 90 degrees in the forward rotation direction.

As the rotating shafts 810 are rotated by 90 degrees in the normal rotation direction, the plate P passing through the engaging groove 812 is lifted up on the large-diameter shaft portion 811 of the rotating shafts 810 and becomes the third The trays are retracted from the conveyor 503, and the above operations are sequentially repeated, and the dishes P sent via the recovery path are sequentially stacked on the large-diameter shaft portions 811 of the two rotating shafts 810. It can be temporarily evacuated.

On the other hand, as described above, both rotating shafts 810
From the state in which a plurality of dishes P are sequentially stacked on the large-diameter shaft portion 811 and temporarily retracted, the dishes P stored in the loading port 21 are washed by the dish washing device 20 and are put thereinto. When the number of dishes P stored in the mouth 21 becomes equal to or less than a predetermined number, an off operation signal is output from the first dish detection device 901 to the controller 900, and accordingly, the controller 90
0 indicates that the second dish detecting device 902 has not detected the dish P for a certain period of time based on the OFF operation signal and the detection signal of the dish P by the second dish detecting device 902, and the third conveyor 503 has a lower portion of the rotating shaft 810 below. When the plate does not come to the position, the drive motor 823 is rotated in the reverse direction to rotate both rotating shafts 810 in the normal rotation direction by 90 degrees. Along with this, in a plurality of plates P stacked on the large-diameter shaft portion 811,
The plate P located on the large diameter shaft portion 811 at the lowest position
After the edge of the plate P has entered the engagement grooves 812 of the rotating shafts 41, the plate P is placed on the third conveyor 503 at the stage where the engagement grooves 812 are rotated to the position where they face each other, and the dish washing device It is conveyed toward 20.

Therefore, in the above-described dish collecting apparatus, the amount of the dish P sent into the dish washing apparatus 20 from the collection path is temporarily reduced, for example, during lunch or dinner, when the shop is crowded with customers. Even if the cleaning capacity of the device 20 can be exceeded,
The dish retreating device 800 can temporarily retreat the dish P on the collection path, so that the dish P stays in the dish inlet 21 of the dish washer 20 and the operation of the entire apparatus is confused. It can be prevented before it happens.
