[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for classifying seeds by size, and for accurately and efficiently sorting seeds into good and defective seeds based on weight, color, and shape. This invention relates to a sorting device.

[Prior Art] A so-called manual sieve is conventionally known as a means for sorting seeds.

[Problems to be Solved by the Invention] However, the conventional method has the following problems.

(i) Although relatively large seeds can be roughly sorted, it has been difficult to sort fine seeds such as flower seeds.

(ii) It was inefficient because a large amount of seeds could not be processed in a short time.

(iii) Although it was possible to sort out the seeds by size, it was not possible to sort out defective seeds in other respects, such as weight (seeds without fruits are light), color, and shape.

In order to solve the above-mentioned problems, the present invention is designed to accurately sort and remove defective seeds and garbage based on not only the size of the seeds but also their weight, color, and shape, and to efficiently sort out good seeds. The purpose of the present invention is to provide a seed sorting device that can be used to sort seeds.

The device (iii) is a combination of the device (i) and the device (ii) in series in a line.

[Example] Hereinafter, a preferred example of the seed sorting device according to the present invention will be described with reference to the drawings.

First, FIG. 1 shows a first embodiment of the apparatus according to the present invention.
This will be explained with reference to FIG. FIG. 1 shows a side view of the apparatus, in which a sieve set 1 is provided on a base 4 with a plate 3 interposed therebetween.

The sieve set 1 includes a first sieve 1a, a second sieve 1b, a third sieve 1c, and a fourth sieve 1d, which are stacked in the order of top to bottom, each having a different mesh size ( (The lower the sieve, the finer the mesh), and the garbage receiving box 1e is placed at the bottom.

This garbage receiving box 1e is placed on the plate 3 and fixed to the plate 3 as necessary. A vibration generator 2 is attached to the plate 3 and has a function of pre-vibrating the sieve set 1.

In this embodiment, the vibration generator 2 is placed next to the stacked sieve set 1, but it may be placed above the vibration generator 2.

Next to the sieve cells i~1, a chute 5 (corresponding to the chute A) having a receiving part 5a and a passage part 5b, which sends the seeds sorted by the sieve set 1, is arranged in the direction of the arrow in FIG. ), and is connected via a stay 6 to a vibration generator 7 that applies vibration to the chute 5. This vibration sends the seeds in the direction of travel under their own weight.

Above the passage section 5b of the chute 5, there is a light
Seed weight processing means 8 is provided for sucking up and processing dust and defective seeds. Since the seed weight processing means 8 does not suck up heavy seeds with fruit, good seeds proceed as they are.

To sort seeds with the seed sorting device of this example,
First, seeds are placed on the top sieve 1a of sieve set 1. Next, the vibration generator a2 is driven to sieve for a certain period of time. As a result, seeds are sorted by the number of sieves depending on their size.

Small garbage is stored in the lowest garbage receiving box 1e.

Next, the seeds that have been sorted and sorted according to size are placed on a slightly wider seed receiver 5a at the end of the chute 5, either manually or automatically by a conveyor (not shown).

The seeds carried to the chute 5 are sent to the chute 5 by a vibration generator 7.
As a result, the chute 5 moves in the inclined direction.

A seed mold ff provided in the middle of the passage portion 5b
1ffi processing means 8 sucks up and disposes of large, light garbage and defective seeds (light because there are no fruits), so that only good seeds with so-called bulges are sorted into the sorting seed box 9. I can do it.

Incidentally, it is preferable to use a transvector (described later) as the seed weight processing means 8 because the device can be simplified and it is economical.

The seed sorting device described above allows for efficient sorting of good seeds.

Next, a second embodiment will be described with reference to FIGS. 3 and 4.

This seed sorting device is a device that can further carefully select good seeds sorted in the first embodiment to seeds with fewer defects.

10 is a barrel, and in front of the barrel 10 is a chute 11 (corresponding to the chute B) (may be a conveyor)
are connected. A color identification means 11 (described in 1) for identifying good or bad seeds according to the color of the seeds from above the chute in the traveling direction of the seeds on the chute 17 (direction of the arrow in FIG. 3); A color defective seed extracting means 12 is provided for extracting color defective seeds identified by reference numeral 11.

Furthermore, in the next step, a shape identifying means 13 is applied to the shoot 17 surface, also from above, to identify whether the shape of the seeds is good or bad.
(described later) is provided, and a defective-shaped seed extracting means 14 for extracting defective-shaped seeds identified by the shape discriminating means 13 is provided near the shape discriminating means 13.

A seed receiving box 15 is installed below the tip of the shoot 17 to receive the selected good seeds.

Next, in order to sort out good seeds and defective seeds using the seed sorting apparatus of the second embodiment, seeds that are not to be sorted are first loaded into the barrel 10 which is being driven.

The seeds charged into the barrel 10 are aligned in a line by the barrel 10 and moved on the chute 17.

The transferred seeds are distinguished from good seeds by color identification means 11 located in the middle of chute 17, and defective seeds are automatically removed by color defective seed extracting means 12, and good seeds are distinguished from good seeds in terms of color. Only the seeds flow on the shoot 17 in a line. Furthermore, in the next step, the shape identifying means 13 identifies whether the shape of the seed is good or bad, and the shapeless seeds are automatically removed by the shapeless seed extracting means 14. As a result, good quality seeds from which defective seeds in terms of color and shape have been removed are finally secured in the seed receiving box 15. It is desirable to use a transvector (described below) for the defective color seed extracting means 12 and the defective shape seed extracting means 14.

FIG. 5 shows the seed weight processing means 8 of the first embodiment and the second
1 to lance vectors which are desirable for use as the defective color seed extracting means 12 and the defective shape seed extracting means 14 of the embodiment are shown.

The principle is that compressed air 29 is regulated by an air valve 28, enters through an inlet 21, and enters a high pressure chamber 22 having a ring-shaped nozzle hole. This ring-shaped nozzle hole restricts the compressed air, and when the primary air pressure passes through the nozzle hole, it is throttled down to atmospheric pressure, the velocity reaches the speed of sound, and the primary air 2
6 is bent toward the discharge port by a small lip on the ring-shaped suction port body, and flows out along the inner surface of the container. Small particles of high-speed secondary air collide with stationary particles around the suction port, give speed to the stationary gas particles, amplify them, and then decelerate, sucking and amplifying 25 air, and passing through the throat. carried to the duct. This suction power is used to dispose of defective seeds.

Color identification means 1 for identifying good and bad colored seeds according to the second embodiment
As an example of 1, a camera device that receives light from target seeds;
It consists of a color identification sensor connected to this and a computer in which the color range of non-defective products is stored in advance. The seeds captured by the camera are sent to a sensor to measure the color range. The measured data is sent to a computer, and compared with pre-stored data, a signal indicating whether it is a good product or a defective product is sent to the color defective seed extracting means 12 (preferably a transvector or an air jet) to determine whether the defective product is defective. Seeds are extracted.

The shape identification means 13 of the second embodiment also includes a front) small camera,
Senna, using a device consisting of a computer. However, the data stored in the computer is shape data.

If one computer is provided with a function of storing color identification data and shape identification data and performing arithmetic processing at the same time, it is possible to combine both means for identifying seeds with defective color and seeds with defective shape into one computer.

Next, a third embodiment (not shown) will be described.

In the third embodiment, the first embodiment shown in FIGS. 1 and 2 and the second embodiment shown in FIGS. 3 and 4 are connected in series in a line, and the apparatus of the second embodiment is It must be connected so that it is on the downstream side. If you explain based on Figures 1 to 4,
The chute 5 of the first embodiment shown in FIG. 1 is extended, and the barrel 10 of the second embodiment shown in FIG. It is directly connected to.

According to the third embodiment, which is a combination of these two embodiments, the grains are uniform, there is no dust mixed in, and the overlapping, color, and shape are good, that is, the size and lff1 points are good. However, it is possible to accurately and efficiently select good seeds in terms of color and shape.
