【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall side view of the agricultural product sorting apparatus, which has a sorting section A and a supply section B. The sorting unit A is configured by mounting a large number of substantially container-shaped receivers 2 for loading the agricultural products P on the endless conveyor 1 composed of an endless rotary chain at a pitch, and the agricultural products (carrots in this embodiment). While the receiver 2 charged with is transported in the direction of the arrow, the weight is weighed by the weighing means 3 provided in the transport path. When the weight is more than the set weight, the receiver 2 is rotated downward to The carrots P placed are dropped into the collection unit 4 and collected by weight. Reference numeral 6 is a sprocket in which the endless conveyor 1 is banded, and 5 is a motor for rotating the sprocket 6. The sorting unit A is the same as that disclosed in Japanese Utility Model Laid-Open No. 2-120420 and Japanese Utility Model Laid-Open No. 1-151883, and a description of the structure of the weighing means 3 and the like will be omitted.

Next, the supply unit B will be described with reference to FIG. The supply section B is composed of a first conveyor 11 and a second conveyor 21. The first conveyer 11 is a roller conveyer, and is constituted by attaching a roller 13 at a pitch to an endless chain 12 banded on a sprocket 14, and on the conveyer 11, the nin in the hopper 10 Gin P is randomly introduced.

The second conveyor 21 comprises a sprocket 22 and an endless chain 23. The chain 7 is arranged on the sprocket 6 of the sorting section A and the sprocket 22 of the second conveyor 21, and the chain 8 is arranged on the sprocket 22 of the second conveyor 21 and the sprocket 14 of the first conveyor 11. Has been done. Therefore, the three conveyors 1, 11, 21 are driven by the same motor 5 to rotate. A carrot P fall prevention plate 27 is obliquely provided along the upper traveling portion of the second conveyor 21, and a gutter-shaped collecting portion 28 is disposed below the upper end portion of the fall prevention plate 27. Has been done.

FIG. 2 is a perspective view of the second conveyor 21, and FIG. 3 is a plan view. An endless chain 23 is banded on the left and right sprockets 22, and long plate-shaped loading bodies 24 (24A, 24B, 24C ...) Are erected at a pitch on the endless chain 23. Both ends of the loading body 24 are attached to the endless chain 23 by bolts 25. Further, five pin-shaped protrusions 26 are erected on a straight line on the upper surface of the loading body 24.

As shown in particular in FIG. 3, the protrusion 26 of the loading body 24A is provided on the left side, and the protrusion 26 of the next loading body 24B is provided on the right side. The protrusion 26 of 24C is provided on the left side. That is, the projecting elements 26 of the loading bodies 24A, 24B, 24C, ... Which lie one behind the other are projectingly provided by alternately shifting the positions to the left and right.

The array length D1 of the protrusions 26 is such that one carrot P having a standard size can be locked, but two carrots P cannot be locked at the same time. Therefore, as shown in FIG. 3, when two or more carrots P1 and P2 are loaded from the first conveyor 11 onto the protrusion 26 of the loading body 24B, the carrot P1 on the right side is locked to the protrusion 26. Then, the carrot P2 is conveyed obliquely upward toward the sorting section A, but the excess carrot P2 on the left side slides downward from the gap D2 on the left side of the protrusion 26 as shown by an arrow N1, and The loading body 24C is engaged with the protrusion 26 of the loading body 24C, and is transported obliquely upward toward the selecting section A by the loading body 24C.

Further, in FIG. 3, the depth W of the loading body 24 has a size capable of supporting one carrot P having a standard size, and cannot support two or more carrots P. Therefore, as shown in the figure, when two carrots PA and PB are vertically stacked and loaded on the load 24A, when the carrots PB are conveyed to the upper end of the fall prevention plate 27, the upper carrot PB is indicated by the arrow N2. As shown in (3), it falls from the fall prevention plate 27 to the collecting section 28 (see also FIGS. 1 and 2).

As described above, when two or more carrots P1 and P2 are loaded on the left and right sides of the loading body 24, the second conveyor 21 places one carrot P2 on the succeeding loading body 24C. When two or more carrots PA and PB are inserted vertically, the carrot PB on the upper side can be dropped into the recovery unit 28. Therefore, finally, only one carrot P is loaded on each loading body 24, and the carrots P can be automatically loaded into the receiving body 2 of the sorting unit A one by one. In this embodiment, the collecting part 28 is a trough, and by providing a gradient to the collecting part 28, the carrot P dropped on the collecting part 28 is shot on the collecting part 28 and discharged laterally. However, the collecting unit may be another system such as a belt conveyor.

This sorting apparatus has the above-mentioned configuration, and the overall operation will be described below. In FIG. 1, the carrots P randomly placed on the hopper 10 are transferred onto the first conveyor 11 at random. Then, the carrot P is conveyed obliquely upward by the conveyor 11 and drops onto the lower end portion of the second conveyor 21. In this case, one carrot P is not always loaded on each loading body 24, and two or more carrots P are likely to be loaded simultaneously. In this case, as described with reference to FIG. 3, the excess carrots (carrots indicated by the symbols P2 and PB) fall from the gap D2 and the fall prevention plate 27, and finally each load On the 24, one carrot P is loaded.

When the loading body 24 rotates along the sprocket 22, the carrot P falls into the receiving body 2 of the sorting section A as indicated by an arrow N3. Then, while being loaded on the receiving body 2 and being transported through the transport path, the weighing means 3 weighs it, and when it has a set weight or more, the receiving body 2 rotates downward and the carrots P are collected by weight in the collecting section 4. To be done.

The present invention is not limited to the above-described embodiment, and for example, the object to be sorted may be potato, sweet potato or the like. Moreover, the hopper 10 and the first conveyor 11 are not always necessary, and the worker may directly and randomly supply the agricultural products P onto the lower end portion of the second conveyor 21. The shape structure of the child 26 is not limited to the above-mentioned embodiment, and any structure having a standard size of agricultural products can be loaded.

[0017]

[Effect of device]

 As described above, according to the present invention, when the agricultural products P are randomly placed on the conveyor 21, the excessive agricultural products P are automatically dropped and only one agricultural product P remains on the loading body 24. Therefore, the agricultural products P can be supplied one by one to the receiver 2 of the sorting unit A and can be weighed one by one by the weighing means 3.
