Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for treating immature edamame and single edamame that are defective products,
This invention relates to an edamame sorting device that can select good quality multi-grain edamame and can process a large amount of edamame continuously.

[Conventional technology]

The applicant has proposed Utility Model Application Publication No. 59-184981, in which green soybeans are fed onto a sorting table with a large number of sorting bodies arranged side by side, and the sorting table is swung back and forth to allow defective green soybeans to fall from between the sorting bodies. Although an edamame sorting device disclosed in the publication was devised, this sorting method has not yet been able to demonstrate excellent practicality because even if the beans are ripe, there are some edamame beans that are defective.

There is also a known sorting method, as in Utility Model Publication No. 60-1478, in which flat plates are simply lined up to create a sorting gap and single grains of edamame fall between the plates; however, with this method, multiple grains of edamame may also fall. However, if the sorting gap is narrowed to prevent this erroneous falling effect, one grain of edamame may be mistakenly transferred, resulting in the drawback that accurate sorting cannot always be carried out.

[Problem to be solved by the invention]

Single-grain edamame, which is treated as a defective product, and multi-grain edamame, which is treated as a good product, are not uniform in size or length, and are transported in various states.
The applicant has developed various sorting devices, and has completed the present invention which can accurately prevent multi-grain edamame from being accidentally dropped and can eliminate and sort single-grain edamame by making further improvements.

[Means to solve the problem]

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

An edamame transporting body 2 for transporting edamame is provided with a swinging mechanism for forwarding the edamame, and the edamame is fitted into the edamame transporting body 2 in the longitudinal direction to form a concave strip 1' which is moved forward by the swinging. 1 are arranged side by side, and a gap S is provided at the bottom of the parallel grooves 1' in which the thin immature edamame and the pod part a' of the single edamame a fall and hang;
A sorting gap l is provided at the end of the edamame conveyor 2, and a sorting body 3 is attached thereto, and an edamame receiving part 4 with a falling guide plate 3'' hanging downward from the first edge 4' of the sorting body 3 is arranged in the conveying direction. The sorting gap l is provided between the edamame receiving part 4 and the end edge of the conveyance guide 1, and a single edamame a falls through the width of the sorting gap 1, but a multi-grain edamame b falls across the width of the sorting gap 1. A partition guide 22 is set to have a width that can be overcome, and a partition guide 22 is arranged in parallel above the sorting gap 1 to maintain the conveyance posture of the multi-grain edamame b in the longitudinal direction and in series with the concave strip 1' of the conveyance guide 1. This relates to an edamame sorting device.

Further, the present invention relates to an edamame sorting device according to claim 1, wherein a distribution plate 12 for distributing the edamame beans to the edamame carriers 2 on an average basis is disposed on the starting end side of the edamame carriers 2.

[Effect]

The edamame beans move forward while being aligned between the conveyance guides 1 while moving slightly due to the rocking of the edamame carrier 2. Since the edamame beans are aligned in the longitudinal direction, the center of gravity of the edamame leaves the end portion 2' of the edamame carrier 2. When it protrudes to the position,
Due to the weight of the edamame itself, the terminal end 2' of the edamame carrier 2
This means that it will fall downwards.

However, if the sorting body 3 is attached to the terminal end 2' of the edamame transporter 2 with a predetermined sorting gap, the tall multi-grain edamame b will be separated from the end 2' of the edamame transporter 2 before its center of gravity separates from the end 2' of the edamame transporter 2. Then, the tip of the edamame reaches the edamame receiving part 4 of the sorting body 3, and it is bridged from the terminal end 2' of the edamame conveyor 2 to the sorting body 3, crosses the sorting gap l, and rides on the sorting body 3 side. It is moved and transported.

On the other hand, for a single edamame (a) that is short, its center of gravity moves away from the terminal end 2' of the edamame transporter 2 before its tip reaches the sorter 3, and the gap S between the transport guides 1 The pod part a' hangs downward from the pod part a', and this hanging pod part a' is the falling guide plate 3'' of the single edamame a.
By hitting the edamame, they are prevented from crossing the sorting gap 1, and fall directly below the terminal end 2' of the edamame carrier 2 to be sorted.

In addition, when the pod part of the multi-grain edamame b curves downward and tries to get over the sorting gap l, if the sorting body 3 is simply a flat plate as in the conventional example, it will crawl under the flat plate, making it impossible to get over the sorting gap l. However, even in such a case, the falling guide plate 3'' will be lifted upward by the inclined surface near the top and will be accurately transferred to the sorting body 3 side.

At this time, since the partition guides 22 erected in accordance with the conveyance guide 1 are arranged in parallel so as to correctly control the conveyance posture of the multi-grain edamame b in the longitudinal direction, the multi-grain edamame b is placed in the left and right partition guides 22, 22. The multi-grain edamame (b) is always conveyed while maintaining the correct longitudinal conveyance posture, and when it crosses the sorting gap l, it does not have a bad conveyance posture that is oblique to the forward direction. Transferring to the side will definitely protect you.

〔Example〕

An example of the illustrated implementation will be described in detail.

A belt conveyor 6 is provided at the bottom of a hopper 5 into which green soybeans are thrown.

An impeller 7 is provided diagonally above the end of the belt conveyor 6 to prevent the edamame from piling up all at once and falling down, and the impeller 7' comes into contact with the edamame that is about to overlap and fall, creating a kicking effect. This makes the average fall better.

The belt conveyor 6 is driven by a motor 8 for intermittent movement via a ratchet mechanism 9, and the illustration shows a case in which the motor 8 also rotates an impeller 7.

Reference numeral 10 in the figure is a belt tension adjustment mechanism.

The green soybeans that are evenly dropped from the belt conveyor 6 are introduced by a lower guide swash plate 11 onto a distribution plate 12 that is placed in a stacked state on the first end side of the green soybean conveyor 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 its rod 16. At this time, the edamame also moves slightly up and down. It moves forward little by little while sliding on the distribution plate 12 and the edamame carrier 2.

At the end of the distribution plate 12, rod-shaped guides 31 are protruded in a staggered manner.
When the edamame becomes horizontally long and collides with the edamame, the edamame is tilted to either the left or right, and the orientation is corrected so that the edamame is always conveyed in the longitudinal direction, and the edamame is sent to the edamame conveyor 2.

Since the edamame conveyor 2 is provided with ridge-shaped conveyance guides 1, the edamame are fitted in the grooves 1' between the conveyance guides 1 in the longitudinal direction, and are conveyed while sliding forward. .

In the figure, reference numeral 17 is a drive motor for the edamame transporter 2, 18 is a support column for the transport guide 1, 19 is a guide mounting portion, and 20 is a guide mounting frame.

A sorting body 3 is provided with a predetermined sorting gap l between the edamame transporter 2 and the multi-grain edamame b at a height where the multi-grain edamame b transfers over in a substantially horizontal state. An edamame receiving part 4 is provided with a hanging guide plate 3'' for guiding the fall of a single edamame (a) onto which the pod part a' of the edamame falls, and a sorting top (corresponding to the first edge 4') with a rear guide 3' arranged in a chevron shape is provided. ), this edamame receiving part 4 is disposed so as to cross the edamame conveying direction, and the sorting gap 1 is formed so that the edamame is separated from the first edge 4' of the sorting body 3 forming the sorting top. A case where the distance (width) to the terminal end 2' of the carrier 2 is shown is shown.

Moreover, a partition guide is arranged in parallel above the sorting gap to maintain the conveying posture of the multi-grain edamame in the longitudinal direction and in the serial direction with the concave stripes of the conveying guide.

In the figure, reference numeral 21 is a sorting box for single edamame a installed below the terminal end 2' of the edamame transporter 2, 22 is a partition guide plate installed for each transport guide 1, and 23 is a mounting whose height can be adjusted. 24 is a support plate, 25 is a long window for adjusting the sorting gap l, and 26 is an adjusting bolt for adjusting the sorting gap l so that a single edamame a does not cross over the sorting gap l.

In addition, a gap S is also provided between the conveyance guides 1 of the edamame conveyor 2, so that the thin immature edamame c falls and the pod part a' of the single edamame a hangs down.
A sorting box 27 for immature edamame c is provided below the edamame carrier 2.

At this time, the gap S is gradually widened toward the end, and if a single edamame a has a pod part a', the pod part a' hangs down from the gap S. The gap S is set to a width that does not allow the edamame beans b to fall.

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

In the present invention, a sorter 3 may be attached to an edamame carrier 2 attached to an edamame peeling machine 30 as shown in FIG.

In this edamame sorting device, the ripe multi-grain edamame b accurately crosses the sorting gap 1 and transfers from the edamame carrier 2 to the sorting body 3 and is conveyed by the above-mentioned sorting action, but the ripe single-grain edamame a Since the pod part a, hanging down from the gap S, hits the fall guide plate 3'', it is prevented from crossing the sorting gap l, and is dropped from the sorting gap l to be sorted.

〔Effect of the invention〕

Since the present invention is configured as described above, single edamame beans cannot cross the sorting gap between the edamame transporter and the sorting body, and are transported to the left and right by the falling guide plate vertically installed on the first edge of the sorting body. The pod of a single edamame that hangs down from between the guides is prevented from hitting and transferring to the sorting body, and the single edamame is dropped from the sorting gap and is sorted. On the other hand, the multi-grain edamame is transferred onto the sorting body through the edamame receiving part provided at the first edge of the sorting body in a direction transverse to the conveying direction of the edamame, and the pods of the multi-grain edamame are transferred onto the sorting body, with the pods of the multi-grain edamame facing downward. Even in a curved state, the upper part of the fall guide plate lifts the multi-grain edamame upwards and promotes the overcoming action accurately.

In addition, at this time, partition guides that control the transport posture of the edamame in the correct longitudinal direction are installed in parallel over the sorting gap in line with the transport guide, so the edamame are always held between the left and right partition guides and the transport posture is always correct in the longitudinal direction. This is a practically excellent edamame sorting device in which the multi-grain edamame is held in place and does not have a bad conveyance position where the edamame is slanted over the sorting gap, so the sorting action of overcoming the sorting gap of the multi-grain edamame is more reliably accomplished. becomes.

In addition, the distribution plate provided at the beginning of the edamame carrier allows the edamame to be evenly distributed to the edamame carrier, resulting in an excellent edamame sorting device that makes the above-mentioned sorting action even more accurate.
