  On the back side of the inclined plate 26 (left side in FIG. 3), a guide plate 32 is provided below the tray collecting hole 24 of the inclined plate 26 so as to guide the collected plate 16 to the collecting unit outside.

  In this example, the guide plate 32 is also a flat plate, similar to the inclined plate 26, and is inclined to the recovery portion at the lower outer side and is fixed to the support frame 28.

  In addition, in order to prevent the dish 16 supplied with the food and drink 14 from being dropped and dropped off from the inclined plate 26, the dish 16 is provided above the inclined plate 26 and the dish guide plate 30. Guide bars 34 for guiding and supporting both ends in the width direction are arranged.

  In this example, the guide bar 34 is a long round bar, the upper part is bent outward and upward, one is closer to the center of the inclined plate 26 in the width direction, and the other is in the width direction of the inclined plate 26. It arrange | positions on the other side, respectively, and it has distribute | arranged so that the both ends of the dish 16 may be located between a pair of guide bars 34. FIG.

  In the figure, 36 is a collection plate support plate disposed on the other side edge in the width direction of the plate collection hole 24, 38 is a collection container as a collection unit, 40 is a hopper, 42 is a dust box, and 44 is a collection unit housing case. Show.

  The process of separating dishes from food and drink using this mechanism will be described in detail below.

  First, the dish 16 on which the food and drink 14 having deteriorated freshness is arranged is supplied from the upper part of the inclined plate 26.

  The supply of the dish 16 on which the food 14 having deteriorated freshness is arranged on the inclined plate 26 is discharged from the conveying path 18 to the collecting path 22 through the discharging means 20, and is moved to the upper part of the inclined plate 26 by the collecting path 22. And transport and supply.

  At this time, the detection of the dish 16 on which the food and drink 14 having deteriorated freshness is arranged is performed by detecting the identification ID given to the dish 16 by the detecting means.

  Next, the dish 16 on which the food and drink 14 are arranged descends rapidly toward the dish guide plate 30 due to the inclination of the inclined plate 26.

  At this time, both ends of the dish 16 on which the food and drink 14 are arranged are guided by the guide bar 34 disposed on the outside of the inclined plate 26 and the dish guide plate 30, so that the dish 16 is dropped or dropped from the inclined plate 26. Can be prevented.

  In addition, the food and drink 14 is forcibly separated from the dish 16 by the impact with the food guide 14 and the dish guide plate 30 due to the load and acceleration of the dish 16 and dropped and discarded to the lower front part.

  The food and drink 14 is disposed in the dust box 42 via the hopper 40.

  Next, only the dish 16 from which the food and drink 14 has been separated moves toward the dish collection hole 24 along the inclined surface of the dish guide plate 30 toward the lower end of the dish collection hole 24.

  Next, when the dish 16 reaches the dish collection hole 24 side, the dish 16 passes through the dish collection hole 24 and tilts toward the back side of the inclined plate 26.

  Next, the tilted plate 16 is dumped into the collection container 38 as a collection unit by the guide plate 32 on the back side of the inclined plate 26, and the collection is completed.
