A large number of gates are provided laterally, and a U-shaped cargo receiving conveyor 2 is provided for each gate.

The producer or organization stores the picked mandarin oranges in a predetermined case and transports them to the fruit-picking area, and first selects a predetermined gate and sets the receipt card 3 received in advance into the card reader 4 of the gate. The carried-in oranges are sent in their cases to the receiving side 2a of the receiving conveyor 2.

The receiving conveyor 2 is driven in the direction of the arrow, and the cases fed thereto are weighed as they are when passing over a weighing device 5 installed on the way, and then the cases are transferred to each receiving conveyor by an overturning guide device 6. The mandarin oranges are placed sideways on the side of the introduction conveyor I, which is arranged in parallel every second, and their bottoms are lifted upwards, and the stored mandarin oranges are received by the introduction conveyor 7. Thrown out at 17a.

The empty case is directly returned to the delivery side 2b by the receiving conveyor 2.

Each introduction conveyor 7 is arranged horizontally behind the receiving conveyor 2, and the oranges received by this introduction conveyor 7 are gradually arranged in rows and sent to the delivery side 7b of each introduction conveyor 7. It will be done.

A first fruit-picking conveyor 8 is disposed in parallel below each introduction conveyor 7, and the receiving side 8a of the first fruit-picking conveyor 8 is arranged in parallel with the lower part of the delivery side 7b of the introduction conveyor 7. Yes, oranges are on the delivery side 7 of the introduction conveyor T.
The fruit falls downward from b, enters the receiving side of the fruit picking conveyor 8, and is sent in the opposite direction on the first fruit picking conveyor 8.

Detectors 9, 9 for automatically sorting the color and size of the oranges are installed on each fruit-picking conveyor 8 at a plurality of locations (six locations in this example) at a required interval from each other along its longitudinal direction. When the oranges pass through these detectors 9, 9, the size and color of the oranges are classified as (excellent), the size and color of the oranges are (excellent), and the size and color of the oranges are (good). It is automatically evaluated in six stages according to the order of products, products for processing, etc.

For example, as shown in FIG. 5, the detector 9 irradiates measurement light from a light source 9a onto the loss conveyor 8, and detects the reflected light from the sent oranges with a light receiver 9b to measure the size. Another similarly configured light receiver 9b for measuring color was used in a front and back arrangement, and was installed at a predetermined position on the sorting conveyor 8 by selection signals from these horizontal hangers 9.9. The distributor 10 is operated to cause predetermined sorting to fall onto the conveyor 11 according to the grade.

The distributor 10 has an operating plate 12 pivoted above the sorting conveyor 8 as shown in FIG.
3a and 13b are rotated alternately, and by the rotation of the operating plate 12, the oranges on the waste conveyor 8 are swept off to the side, and the sorted oranges are caused to fall onto the conveyor 11.

For sorting, a plurality of conveyors 11 (six in the embodiment) are installed in common with each fruit-picking conveyor 8 in a direction perpendicular to the fruit-picking conveyor 8. The sorted items are sent to the delivery side of the conveyor 11.

In this way, each orange on the returning conveyor 8 is automatically evaluated and sorted into each grade.
Receiving card 3 dynamically displays the ratio of size, equal edge, defective products, and non-standard products for each grade, as well as the initial receiving weight and force.
printed and returned to the producer.

The mandarin oranges brought in by each producer are handled using conveyor lines for each producer, from the gate, receiving conveyor 2, introduction conveyor 7, and fruit sorting conveyor 8. From now on, the separated mandarin oranges will be handled together, regardless of producer.

For each sort, the oranges that have reached the delivery side of the conveyor 11 are stored in a storage case 14 disposed at the terminal thereof, and are sent out onto the seasonal conveyor 15.

The storage case 14 is arranged such that each grade is distributed to each conveyor 11 by a box supply conveyor 16, and each time the storage case 14 at the tangerine receiving position becomes full and is sent onto the conveyor 15. The next new housing case is set at the orange receiving position.

When the number of storage boxes on the timing conveyor 15 reaches a predetermined number, the detector that detects this issues a signal to the self-propelled transport vehicle 17.
