Since the agricultural products are configured to be supplied to the starting end of the sorting conveyor by dropping the agricultural products onto a bucket of the sorting conveyor via a transfer guide (chute) or directly, there are the following problems. I have.

[0005] That is, when agricultural products are supplied to the sorting conveyor, the agricultural products may fluctuate or shake on the receiving tray to change the attitude thereof to the state at the time of the pitching conveyor, and the agricultural products may jump out of the receiving tray. Produces can easily harm agricultural products, as they may protrude. In addition, due to the change in the attitude of the agricultural products on the sorting conveyor or the jumping out of the agricultural products, it is necessary to manually correct the attitude and the like of the agricultural products, which makes it difficult to automatically save labor in the sorting and packaging of the agricultural products. Furthermore, it is necessary to secure a predetermined distance between the starting end of the sorting conveyor and the measuring device downstream from the sorting conveyor so that the swing of the agricultural products supplied on the sorting conveyor can be eliminated. The length of the machine is lengthened, so that the installation space of the sorting and packaging facility is wasted and the cost is likely to increase.

Further, when the agricultural product protrudes (is deviated) from the mounting position (approximately central portion) on the tray, for example, the angle of view and the brightness of the illumination related to the imaging of the camera of the measuring device arranged at a predetermined position of the sorting conveyor are reduced. In some cases, it is difficult to capture an accurate image, which may have an adverse effect on the measurement accuracy of the grade, weight, or internal quality of agricultural products.For example, measurement on a sorting conveyor to improve the efficiency of sorting work When agricultural products are supplied to the apparatus at a high speed, the sway of the agricultural products is further increased, and the recent sensor technology cannot cope with the fluctuations, which makes it difficult to speed up the sorting conveyor.

On the other hand, it is conceivable to form the tray of the sorting conveyor in a deep shape so as to prevent the agricultural products from jumping out when supplied, as much as possible. In addition, there is a problem that the exposed portion of the agricultural product is reduced, the imaging field of view is narrowed, and the sorting accuracy is deteriorated.
In other words, in this type of sorting conveyor, in order to supply produce to the saucer in a stable posture, the saucer may be of a deep type, but in order to capture an image with an optical sensor, the contact surface between the saucer and the produce is required. There is a need for a contradictory function regarding the setting of the tray of the sorting conveyor to minimize the (exposed part) as much as possible and widen the measurable imaging field of view. Currently, there is a supply device that satisfies such a function. In fact, it is hoped that they will appear.
