そして、きゅうり１の撮影画像データがビデオカメラ１０から選別コントローラ１２に入力される（Ｓ２）。また、バケット５のマーカー読取りデータがバケットセンサ１１から選別コントローラ１２に入力される（Ｓ３）。   The captured image data of the cucumber 1 is input from the video camera 10 to the sorting controller 12 (S2). Further, marker reading data of the bucket 5 is input from the bucket sensor 11 to the sorting controller 12 (S3).

選別コントローラ１２では、ビデオカメラ１０からのきゅうり１の撮影画像データに基づき、きゅうり１の形状（長さ、太さ、形）を画像処理にて演算して、Ａ級品のきゅうり１、Ｂ級品のきゅうり１、Ｃ級品のきゅうり１、及びそれ以外の等級外のきゅうり１に選別する。Ａ級品のきゅうり１、Ｂ級品のきゅうり１、Ｃ級品のきゅうり１の形状データの基準値は、選別コントローラ１２のメモリに予め記憶させている。きゅうり１の撮影画像データと、きゅうり１の形状データの基準値とを対比して、きゅうり１が、Ａ級品であるか、Ｂ級品であるか、Ｃ級品であるか、またはそれ以外の等級外のいずれであるかを判定され、自動的に選別される。   The sorting controller 12 calculates the shape (length, thickness, shape) of the cucumber 1 based on the imaged image data of the cucumber 1 from the video camera 10 by image processing, and class A cucumbers 1 and B Sorted into cucumber 1 of the product, cucumber 1 of the C-class product, and cucumber 1 of the other grade. The reference values of the shape data of the A-class cucumber 1, the B-class cucumber 1, and the C-class cucumber 1 are stored in the memory of the selection controller 12 in advance. By comparing the cucumber 1 photographed image data with the reference value of the cucumber 1 shape data, the cucumber 1 is a class A product, a class B product, a class C product, or otherwise. It is judged whether it is out of the grade, and it is automatically selected.

また、選別コントローラ１２では、選別部８において自動的に選別されたきゅうり１が、選別部８から各引出コンベヤ３ａ，３ｂ，３ｃの仕分け部１３，１４，１５に到達するのに必要な落下位置到達時間を演算する（Ｓ４）。選別されたきゅうり１の落下位置到達時間は、バケット５の移動速度と、選別部８と仕分け部１３，１４，１５との間のバケット５の移動距離Ｌとから算出される。   Further, in the sorting controller 12, the cucumber 1 automatically sorted by the sorting unit 8 is a drop position necessary for reaching from the sorting unit 8 to the sorting units 13, 14, and 15 of the drawer conveyors 3a, 3b, and 3c. The arrival time is calculated (S4). The drop position arrival time of the selected cucumber 1 is calculated from the moving speed of the bucket 5 and the moving distance L of the bucket 5 between the selecting unit 8 and the sorting units 13, 14, 15.

各引出コンベヤ３ａ，３ｂ，３ｃの仕分け部１３，１４，１５に、該当する等級品のきゅうり１を載せたバケット５が到達したとき（Ｓ５：ｙｅｓ）、即ちバケット５の移動速度と移動距離Ｌから演算された落下位置到達時間より若干手前の時期になったときに、前記バケット５識別データと等級別データとの対のデータに基づき、該当するＡ級品用またはＢ級品用またはＣ級品用のいずれかの引出コンベヤモータ２０，２１，２２を始動させて、各引出コンベヤ３ａ，３ｂ，３ｃのいずれかを作動させる（Ｓ６）。そして、Ｔ１時間（引出コンベヤモータ２０，２１，２２の始動から、引出コンベヤ３ａ，３ｂ，３ｃの搬送速度が選別コンベヤ２の搬送速度と等しくなるまでに要する時間）が経過した場合（Ｓ７：ｙｅｓ）、バケット５上のきゅうり１に該当するＡ級品用またはＢ級品用またはＣ級品用のいずれかの落下機構１６，１７，１８が作動し、バケット５上のきゅうり１を、バケット５と略等しい移動速度のエンドレス平ベルト１９の上面に落下させる。このように、選別されたきゅうり１の落下位置到達時間を予測して、そのきゅうり１に該当する引出コンベヤモータ２０，２１，２２を、きゅうり１が落下位置に到達する前に始動させ、選別されたきゅうり１が落下位置に到達する直前に、バケット５の移動速度と、エンドレス平ベルト１９の移動速度とが略等しくなるように制御し、バケット５とエンドレス平ベルト１９の移動速度差を殆どなくしてきゅうり１の落下衝撃を低減させる。   When the bucket 5 carrying the cucumber 1 of the corresponding grade product arrives at the sorting sections 13, 14, 15 of each of the drawer conveyors 3a, 3b, 3c (S5: yes), that is, the moving speed and moving distance L of the bucket 5 Based on the paired data of the bucket 5 identification data and the grade-specific data at the time slightly before the drop position arrival time calculated from the above, for the corresponding Class A product, Class B product, or Class C Any of the drawer conveyor motors 20, 21, 22 for the product is started to operate any of the drawer conveyors 3a, 3b, 3c (S6). And when T1 time (time required for the conveyance speed of the drawer conveyors 3a, 3b, 3c to become equal to the conveyance speed of the sorting conveyor 2 from the start of the drawer conveyor motors 20, 21, 22) has elapsed (S7: yes) ) Any of the drop mechanisms 16, 17, 18 for class A products, class B products or class C products corresponding to the cucumber 1 on the bucket 5 is operated, and the cucumber 1 on the bucket 5 is Is dropped onto the upper surface of the endless flat belt 19 having a moving speed substantially equal to the above. Thus, the drop position arrival time of the selected cucumber 1 is predicted, and the drawer conveyor motors 20, 21, and 22 corresponding to the cucumber 1 are started before the cucumber 1 reaches the drop position. Immediately before the cucumber 1 reaches the drop position, the moving speed of the bucket 5 and the moving speed of the endless flat belt 19 are controlled to be substantially equal, and the moving speed difference between the bucket 5 and the endless flat belt 19 is almost eliminated. The drop impact of the cucumber 1 is reduced.

同じ仕分け部１３，１４，１５において、その仕分け部１３，１４，１５に該当する等級品のきゅうり１を載せたバケット５が連続して到達する場合（Ｓ８：ｙｅｓ）、上述したステップ５に戻ってエンドレス平ベルト１９を連続して移動させ、次のバケット５からきゅうり１が落下したときに、そのきゅうり１がエンドレス平ベルト１９上のきゅうり１に衝突するのを防止する。   In the same sorting unit 13, 14, 15, when the bucket 5 on which the cucumber 1 of the grade corresponding to the sorting unit 13, 14, 15 is continuously reached (S8: yes), the process returns to the above-described step 5 The endless flat belt 19 is continuously moved, and when the cucumber 1 falls from the next bucket 5, the cucumber 1 is prevented from colliding with the cucumber 1 on the endless flat belt 19.

一方、同じ仕分け部１３，１４，１５において、その仕分け部１３，１４，１５に該当する等級品のきゅうり１を載せたバケット５が連続して到達しない場合（Ｓ８：ｎｏ）、その仕分け部１３，１４，１５に該当する引出コンベヤモータ２０，２１，２２をＯＦＦにして引出コンベヤ３ａ，３ｂ，３ｃを停止させる（Ｓ９）。このように、各仕分け部１，１４，１５において、所定の等級のきゅうり１を落下排出する時間間隔が短かいときには、引出コンベヤ３ａ，３ｂ，３ｃを連続して作動させる一方、その時間間隔が長いときには、次のきゅうり１が落下排出される直前まで前記引出コンベヤ３ａ，３ｂ，３ｃを停止させる。したがって、同じ等級品の複数本のきゅうり１を、これに該当する引出コンベヤ３ａ，３ｂ，３ｃのエンドレス平ベルト１９上に短い略等間隔に整列させて一時的に保管することができる。エンドレス平ベルト１９の上面を、同じ等級品のきゅうり１の一時的な貯蔵場所として利用できる。   On the other hand, in the same sorting unit 13, 14, 15, when the bucket 5 on which the cucumber 1 of the grade corresponding to the sorting unit 13, 14, 15 is not continuously reached (S 8: no), the sorting unit 13 , 14 and 15 are turned off, and the drawer conveyors 3a, 3b and 3c are stopped (S9). Thus, when the time intervals for dropping and discharging the cucumbers 1 of a predetermined grade are short in the sorting sections 1, 14, and 15, the drawer conveyors 3a, 3b, and 3c are continuously operated, while the time intervals are When it is long, the drawer conveyors 3a, 3b, 3c are stopped until immediately before the next cucumber 1 is dropped and discharged. Therefore, a plurality of cucumbers 1 of the same grade can be temporarily stored on the endless flat belt 19 of the corresponding drawer conveyors 3a, 3b, 3c in a short and substantially equal interval. The upper surface of the endless flat belt 19 can be used as a temporary storage place for cucumbers 1 of the same grade.
