Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edamame sorting apparatus capable of sorting defective one-grain edamame and non-defective one-grain edamame.

[0002]

2. Description of the Related Art Applicants send edamame onto a sorting table having a large number of sorting bodies arranged side by side and swing the sorting table in the front-back direction to drop and sort defective green soybeans from between the sorting bodies. Sho 59
Although the edamame sorting apparatus disclosed in Japanese Patent No. 184981 was devised, even if the beans were ripe, there was a single grain that was a defective product, so that this sorting method could not yet exhibit excellent practicability.

Further, there is also known a sorting method in which flat plates are simply arranged to form a sorting gap and one grain edamame is dropped between the flat plates, as in Japanese Utility Model Publication No. 60-1478. When the tip of the pod hits the edge of the flat plate, and the tip of the pod, which is often curved, is located below the edge of the flat plate, it cannot be transferred onto the flat plate.
Will fall. If the selection gap is narrowed in order to prevent this erroneous dropping action, one edamame bean may be accidentally transferred, and there is a drawback that accurate selection is not always performed.

[0004]

The one edamame, which is treated as a defective product, is not constant in size or length, and is transported in various states. The applicant has developed various sorters, but after further improvement, he completed the present invention for accurately eliminating and sorting one edamame.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

[0006] A edamame carrier 2 in which a conveyance guide 1 for conveying edamame in the longitudinal direction is arranged side by side, and a sorting body 3 for receiving and transporting only the multi-grain edamame b is provided with a sorting gap in which one grain soybean a falls. The edamame sorting machine is characterized in that when the pod portion b'of the compound edamame b hits the first edge 4'of the sorting body 3, a lifting surface 4 "is formed to convey the compound edamame b upward. It is related to.

[0007]

The green soybeans, which are finely moved by the swinging movement of the green soybean carrier 2 and are aligned between the transport guides 1 and transported, are aligned in the longitudinal direction, so that the center of gravity of the green soybeans is at the end portion of the green soybean carrier 2. When protruding to a position away from 2 ', it becomes the reason that the weight of the green soybean itself causes the green soybeans to drop downward from the terminal end 2'of the green soybean carrier 2.

However, when the sorting body 3 is provided side by side with the predetermined sorting gap L at the end portion 2'of the soybean carrier 2, the tall compound grain soybean b has its center of gravity at the end portion 2 of the soybean carrier 2. '
As shown in FIG. 5, the tip of the pod part b ′ of the composite grain edamame b reaches the first edge 4 ′ of the sorting body 3 before being separated from the end portion 2 ′ of the edamame carrier 2 as shown in FIG. In the state of being bridged to the body 3, the selection gap L is overcome, and the pod portion b ′ of the multi-grained soybean b is curved downward and the initial edge 4 ′ of the selection body 3 is temporarily curved.
As shown in FIG. 7, when the vehicle is positioned on the lower side and is advanced as it is, even if it is impossible to transfer to the sorting body 3 as shown in FIG. Is lifted upward, and is transferred to the sorting body 3 side.

On the other hand, one grain green soybean a, which is short,
Since the center of gravity of the edamame carrier 2 deviates from the terminal end 2 ′ of the edamame carrier 2 before the tip reaches the end of the edamame carrier 2, it cannot be prevented from getting over the sorting gap L and directly below the terminal end 2 ′ of the edamame carrier 2. Be dropped and sorted.

[0010]

EXAMPLE An example of the illustrated embodiment will be described in detail.

A belt conveyor 6 is provided at the bottom of the hopper 5 into which edamame is put.

A rotary impeller 7 is provided diagonally above the end of the belt conveyor 6 to prevent the edamame from overlapping and dropping all at once. Will be exhibited and the average fall will be improved.

The belt conveyor 6 is driven by a motor 8 via a ratchet mechanism 9 so as to be intermittently moved, and the motor 8 is also used to rotate the impeller 7. Reference numeral 10 in the drawing is a belt tension adjusting mechanism. The green soybeans that are dropped from the belt conveyor 6 on average are introduced by a lower guide swash plate 11 onto a distribution plate 12 placed in a superposed state on the initial end side of the green soybean carrier 2.

The distribution plate 12 and the edamame carrier 2 are supported by a link mechanism 13 and a spring mechanism 14, and are swung back and forth by an eccentric mechanism 15 and a rod 16 thereof, and at the same time, they are slightly moved up and down. The green soybeans slide on the distribution plate 12 and the green soybean carrier 2 and gradually move forward.

Since the bar-shaped guides 31 project in a staggered manner at the end of the distribution plate 12, when the edamame hits the bar-shaped guides 31 in a horizontally long position, the edamame is inclined to the left or right and the edamame is always conveyed in the longitudinal direction. Correct the direction as described, and then soybean carrier 2
Send it to.

The edamame carrier 2 has a ridge-shaped carrier guide 1.
Since the soybeans are arranged side by side, the soybeans are fitted between the conveying guides 1 in the longitudinal direction, and are moved in a sliding motion to be conveyed.

In the figure, reference numeral 17 is a drive motor for the edamame carrier 2, 18 is a support pillar for the carrier guide 1, 19 is a guide mounting portion, 20
Is a guide mounting frame.

A sorting body 3 is provided at a predetermined sorting gap L from the edamame carrier 2 at a height at which the multi-grain edamame b is transferred in a substantially horizontal state. The pod portion b ′ of the grain edamame b hits and the edamame receiving portion 4 is formed by the front guide plate 3 ″ provided with the lifting surface 4 ″ for lifting the compound edamame b upward and the rear guide plate 3 ′. An example of an embodiment in which the top of the edamame receiving portion 4 is formed at the first end edge 4'is shown, and the edamame receiving portion 4 (sorting top portion) is arranged so as to cross the edamame transport direction, and the sorting gap L is First edge 4'of sorting body 3
It shows a case where the distance (width) from the end portion 2'of the soybean carrier 2 is set.

In FIG. 6, the line YY indicates the forward position of the lower edge of the compound edamame, and the line Y'-Y 'indicates the center line in the lengthwise direction of the compound edamame. When the tip of the pod b'is curved downward and is positioned below the first end edge 4'of the sorting body 3 and is advanced as it is, it is impossible to transfer to the sorting body 3 as shown in FIG. However, it is lifted upward as shown in FIG. 7 by the lifting surface 4 ″ formed on the first end edge 4 ′ of the sorting body 3 and transferred to the sorting body 3 side.

In the figure, reference numeral 21 is a sorting box for one grain edamame a, which is installed below the terminal end 2'of the edamame carrier 2, and 22 is the transport guide 1.
Partition guide plates that are erected for each, 23 is a mounting portion whose mounting height can be adjusted, 24 is a support plate, 25 is a long window that adjusts the selection gap L,
26 is an adjusting bolt for adjusting the selection gap L so that one grain soybean a does not get over the selection gap L.

A gap S is also provided between the transport guides 1 of the green soybean carrier 2 so that the thin unripe green soybeans c may fall.
A selection box 27 for the immature edamame c is provided below the edamame carrier 2.

At this time, the gap S is formed so that it gradually becomes wider toward the end, and in the case where the pod portion a ′ of one grain soybean a exists, the pod portion a ′ hangs down from the gap S, but a ripe one grain edamame a
The gap S is set to a width such that or the soybean beans b does not fall.

Further, a downflow gutter 28 is provided on the side of the sorting body 3, and a sorting box 29 for the compound grain edamame b is provided below it.

In the present invention, the sorting body 3 may be attached to the edamame carrier 2 attached to the edamame scraping machine 30 as shown in FIG.

In this edamame sorting device, the compound edamame b that has been ripe by the above-mentioned sorting operation is accurately transported over the sorting gap L and transferred from the edamame transporting body 2 to the sorting body 3.
The ripe single edamame a hits the guide plate 3 ″ on the front side of the sorting body 3 in a state where the pod portion a ′ hangs down from the spacing S, so that it does not get over the sorting gap L, and is dropped and sorted from the sorting gap L. ..

[0026]

Since the present invention is configured as described above, one grain edamame can not get over the sorting gap between the edamame carrier and the sorting body, and falls and is sorted from the sorting gap. On the other hand, the multi-grain edamame is transferred to the sorting body over the sorting gap through the edamame receiving part provided at the first end edge of the sorting body in a direction transverse to the edamame transport direction, and the tip of the pod portion of the multi-grain edamame is transferred. Since it is curved downwards, it is positioned below the sorting body and if it moves forward as it is, even if it is not possible to transfer to the sorting body, it is lifted upward by the lifting surface formed on the sorting body and conveyed, so it is reliable It becomes a practically excellent green soybean sorting device that forces you to transfer to the green soybeans and sorts them without accidentally dropping them.
