Description

[Detailed description of the invention] The present invention relates to a fruit sorting device that is used to sort fruits such as Satsuma mandarin oranges, navels, Iyokan oranges, pears, apples, etc. into multiple sizes according to standards, etc. It is.

Conventionally used sorting equipment has a plurality of rotating drums, each having different sized sorting holes, arranged side by side, and while the fruits are being transferred over the rotating drums, the fruits to be selected are dropped in order from the smallest to the next to be sorted. In this method, a plurality of supporting members are arranged on a flat surface and the falling holes are sequentially expanded during transport, so that the fruits to be selected are dropped in order from the smallest to different positions for sorting. There is something I did.

However, in the former method, the selected fruits are not only rolled on a rotating drum, but also the selected fruits caught in the sorting hole are forcibly thrown up, so an impact force is applied to the selected fruits and the fruits are not picked. It could not be used for sorting high-quality fruits because it would damage the selected fruit.

In addition, the latter type has a structure in which a plurality of supporting members are sequentially expanded during transportation, making the structure extremely complicated and expensive.

Therefore, the present invention stacks a plurality of receiving members in the vertical direction, and each receiving member is provided with a sorting hole whose diameter is larger for the lower receiving member, so that the stacked receiving members are rotated downward in order from the lower receiving member while being transported. The present invention attempts to provide a sorting device which solves the above-mentioned drawbacks at once by having a structure in which selected fruits, etc. are dropped at different positions depending on their size.

An embodiment of the present invention will be described below in detail with reference to the drawings.

Similarly, the third horizontal guide 4C is arranged so as to contact the lower surface of the locking part 6C of the third receiving member 2C and horizontally support the third receiving member 2C in the third section C. 2
C rotates downward due to its own weight at a position past the third section.

Reference numeral 10 denotes an inclined guide, which is in contact with the first receiving member 2a side of the stacked body 2 being transferred in a hanging state at the front end E of the transfer body 3 to guide the stacked body 2 to a horizontal state; It is fixedly provided on the frame 3a and communicates with the front end 4a' of the first horizontal guide 4a.

Reference numeral 11 denotes a chute for supplying fruits to the sorting holes 5 a , 5 b , 5 C of the stack 2 which is horizontally supported and transferred by the first horizontal guide 4 a.

The first belt conveyor 12a is located at the bottom of the first section A.
The conveyor 12b is connected to the third conveyor 1 at the bottom of the second section B.
2C are arranged at the bottom of the third section C, respectively.

A case where fruits are sorted using the sorting device 1 configured as described above will be explained.

Fruit K is supplied to the chute 11.

Then, the fruit K is transferred by the transfer body 3 in the direction of the arrow along the transfer path R while being placed on the stack 2 passing through the lower part of the chute 11 and transferred rearward.

When the stacked body 2 passes through the first horizontal guide 4a, the support of the first receiving member 2a by the first horizontal guide 4a is released, so that the first receiving member 2a rotates downward around the ring 9 due to its own weight. However, the second receiving member 2b is still maintained horizontally by the second horizontal guide 4b.

At this time, S is smaller than the second screening hole 5b of the second receiving member 2b.
A fruit K of the same size falls from the first receiving member 2a, moves onto the first belt conveyor 12a, and transfers to the first belt conveyor 12.

At this time, M is smaller than the third screening hole 5C of the third receiving member 2C.
A fruit K of the same size falls from the second receiving member 2b and moves onto the second belt conveyor 12b, and is transferred to the second belt 1/conveyor 1.
2 b is ejected laterally.

After that, when the stacked body 2 passes through the third horizontal guide 4C, the support of the third receiving member 2C by the third horizontal guide 4C is released, so that the third receiving member 2C rotates downward around the ring 9 due to its own weight. and the L caught in the third sorting hole 5C.
A fruit of size K falls onto the third belt conveyor 12C.
It moves upward and is discharged to the side by the third belt conveyor 12C.

The stacked body 2, all of which has been rotated downward in this manner, is transferred forward via the rear part D of the transfer body 3.

Then, it is guided by the inclined guide 10 at the front part E of the transfer body 3, becomes horizontal again, and moves onto the first horizontal guide 4a.

Thereafter, the subsequent stacked body 2 is sorted by repeating the same operation as above and dropping the fruits K according to the sizes L, M, and S at different positions.

In the embodiment described above, the sorting is carried out only in the transfer section on one of the left and right sides of the transfer body 3, but it is also possible to carry out the sorting both in a reciprocating manner in the transfer sections on both the left and right sides.

In that case, you can not only improve the efficiency of sorting work, but also
It is also possible to sort two types of fruits at the same time.

As shown in the above embodiments, the sorting device of the present invention has a transfer body capable of transferring along a horizontal plane, and a plurality of receiving members for placing objects to be sorted are stacked in the vertical direction to transfer the side part of a certain stacked body. Each receiving member of the stacked body is provided with a selection hole corresponding to the upper and lower sides, the diameter of which is larger in the upper receiving member than the lower receiving member, so that the diameter of the stacked receiving members is Since the structure is such that the lower receiving member having a small sorting hole is rotated downward in order, the objects to be sorted placed in the sorting hole of the laminate can be dropped and sorted at different positions in order from the smallest one. Can be done.

Moreover, since the items to be sorted are placed into the sorting hole of the receiving member and are transferred while stationary, the items can be sorted without actively applying impact force to the items, so even high-quality fruits that are easily perishable can be sorted. Can be used stably.

In addition, the device of the present invention is designed to sort the stacked bodies while transporting them on the same horizontal plane -E, so the entire conveying body can be used effectively from start to finish for sorting, and the empty feeding section of the stacked bodies can be used effectively. Since the amount can be reduced, the sorting efficiency can be further improved.
