Abstract

PURPOSE: To provide a selecting apparatus which can carry out selection of floricultural products while satisfying both the length and weight for floricultural products, e.g. flowers. CONSTITUTION: In the case where a flower P is detected by a first touch-type sensor 12A, a slider 16 is transported from an upper stage guide rail 20 to a lower stage guide rail 21A and then weighing is carried out by a first weighing means 30A and in the case that the flower P has enough weight to satisfy a set weight, the flower P is dropped in a first recovery part. In the case where a flower P is not detected by the first touch-type sensor 12A and does not have the weight to satisfy the set weight of the first weighing means 30A, the flower is put in a lower class and selection for the flower is carried out in the same way by a second touch-type sensor 12B and a second weighing means 30B. In this way, while selecting gradually in the lower classes, selection is carried out, so that selection can be carried out while satisfying both required length and weight.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural product sorter for sorting by combining length and weight.

[0002]

2. Description of the Related Art A sorting machine has been proposed which is capable of sorting the length and weight of a flower (Saikaihei 4-78974).
Issue). This sensor has length sensors 42a to 42c (reference numerals are used in the same publication, which are length detection means) on the conveyance path of the chrysanthemum K.
The same shall apply hereinafter) and a weight scale 46 is provided behind the length sensors 42a to 42c. The chrysanthemum K is first sorted by the length sensors 42a to 42c by length, and then the weight K is measured. The scale 46 is used to sort by weight.

FIG. 6 illustrates the sorting method of the above-mentioned conventional means in a simplified and easy-to-understand manner. When the chrysanthemum K is detected by the first length sensor 42a, the support rod 33 moves from the first rail 34 to the lower second rail 35 (arrow N).
1), the weighing boxes 46 provided in the middle of the second rail 35 are weighed.
b, 41c (arrows N11, N12, N1
3). Therefore, the first input box 41a is long and heavy (long and heavy), the second input box 41b is long and medium-weight (long and medium weight), and the third input box 41c is long and heavy. Light (long and light) chrysanthemum K is collected.

The chrysanthemum K, which is not detected by the first length sensor 42a, further moves to the left on the first rail 34 (arrow N2), and when detected by the second length sensor 42b. The first rail 34 moves to the lower second rail 35. While moving to the left on the second rail 35,
The weight is weighed by a weight scale 46 provided on the way, and the heaviest ones are sequentially dropped into the input boxes 41d, 41e, 41f. Therefore, the fourth loading box 41d is medium / heavy (medium in length and heavy), the fifth loading box 41e is medium / medium in weight (medium in length and medium in weight), and the sixth Medium and light (medium length and light weight) chrysanthemums K are collected in the input box 41f.
Further, although omitted in FIG. 6, the short / heavy and short / similar cases are similarly applied to the input boxes 41g, 41h, and 41i further downstream.
Medium-heavy, short and light chrysanthemum K are collected respectively.

[0005]

By the way, flowers such as chrysanthemums are marketed to the market in three stages: first grade (long / heavy), second grade (medium / medium heavy), and third grade (short / light). In many cases, they are shipped in different classes. That is, in FIG. 6 described above,
The one dropped into the first input box 41a is the first grade (long / heavy)
However, those falling into the second charging box 41b and the third charging box 41c satisfy the length but not the weight, and are therefore not the first grade but the second grade or lower. Therefore, in the above-mentioned conventional sorting machine, the flowers dropped in the second input box 41b and the third input box 41c are weighed again to be the second or third grade.
There was a problem in that it had to be re-sorted into classes, which would be an extremely heavy labor burden for farmers. Of course, it is sorted by the second length sensor 42b and the
Dropped into the input boxes 41d, 41e, 41f, or sorted by the third length sensor 42c, the seventh, eighth, and ninth boxes.
The same applies to those dropped into the input boxes 41g, 41h, and 41i, and the sorting of these must be performed again.

In other words, in this type of flower sorting machine, only those satisfying both length and weight are sorted into a predetermined class, and those satisfying only one of them are: It will be dropped to a lower class.
Therefore, an object of the present invention is to provide a sorter for agricultural products which can collect only those satisfying both the length and the weight in a predetermined collecting part, and therefore does not need to perform the sorting again.

Next, referring to FIG. 2, the first weighing means 3
0A will be described. The first weighing means 30A includes a rotary rod 31
And a weight 32, and the rotary rod 31 has a frame 33.
Is rotatably supported by the pin 34 in the vertical direction. The tip portion 311a of the rotary rod 31 is at a position that complements the cutout portion of the lower guide rail 21A (see also FIG. 3). When the weight of the flower P is heavier than the weight set by the weight 32 with the slider 16 transferred onto the tip portion 311a, the rotary rod 3
1 rotates downward about the pin 34, and the tip portion 311a descends. Then, the slider 16 cannot be transferred to the next lower guide rail 21A from the terminal end of the tip 311a and falls (see arrow N2 in FIG. 3). Then, as described above, the support 4 rotates downward, and the flower P falls. The other weighing means 30B and 30C also have the same structure, and as shown in FIGS. 2 and 3, the tip end portions 312a and 3a of the rotary rods 31 respectively.
Reference numeral 13a complements the cutout portions of the lower guide rails 22A and 23A. That is, the weighing means 30A, 30B, 30
C is a drop means for dropping the agricultural product P downward. Further, as shown in FIG. 3, each of the tip end portions 311a and 312 is
a, 313a below the collecting portion 13A, 13B, 13C
Is provided.

The flower sorter is constructed as described above, and the sorting operation will be described below. In FIG. 1, the flowers P on the supply table 10 are laid one by one on the support 4 and conveyed to the right. As shown in FIG. 2, the slider 16 on the side of the support 4 on which the flower P is placed is
Slide on the upper guide rail 20 to the left. The first touch type sensor 12 is provided on the conveyance path by the upper guide rail 20.
The lever 12a of A is hanging down. When the flower P hits the lever 12a, since the flower P has a predetermined length, the solenoid 43 of the first opening / closing section 40A is actuated, and the guide body 41A retreats sideways. This moving out operation is shown in FIG.
And as described with reference to FIG. Then, the slider 16 falls and moves onto the first lower guide rail 21A (see arrow N1 in FIG. 3).

Next, the slider 16 slides to the left in FIG. 3, and the tip portion 3 of the rotary rod 31 of the first weighing means 30A.
Transfer to 11a. If the flower P is heavier than the weight set by the weight 32, the tip 311a is lowered, the slider 16 is dropped (arrow N2), the support 4 is rotated downward, and the flower P is the first recovery part. It falls to 13A. That is, the first collection unit 13A collects the long / heavy, that is, the long and heavy first-class flower PA.

Now, in FIG. 3, the flower P is the lever 12a.
If it does not hit, the slider 16 drops from the end portion of the upper guide rail 20 onto the inclined guide rail 21B as shown by the arrow N3, and moves to the upper guide rail 21C. Further, when the flower P is lighter than the weight set by the first weighing means 30A, the slider 16 moves leftward as shown by an arrow N4, and moves from the inclined guide rail 21B to the upper guide rail C. That is, the first touch sensor 12A and the first weighing means 30A are for selecting the first-class flower PA that satisfies both the length and the weight, and the flower P that is not satisfied by either one is , Arrow N
As indicated by reference numerals 3 and N4, the second touch type sensor 12B for selecting the next second-class flower arrangement P and the second weighing means 30B are sent to the second touch type sensor 12B, and the classification is performed by dropping the class by one rank.

The lever 12b of the second touch type sensor 12B is vertically provided on the conveying path of the flower P by the upper guide rail 21C, and the same operation as described above is repeated. That is, when the flower P hits the lever 12b, the arrow N5
As shown by, the slider 16 falls and moves onto the lower guide rail 22A and slides to the left. When the weight is set by the second weighing means 30B, the arrow N6
As shown by, it falls into the second recovery unit 13B. If the flower P does not hit the lever 12b, the slider 16 falls from the upper guide rail 21C to the inclined guide rail 22B as shown by an arrow N7, and the next upper guide rail 22C is reached.
Move to. When the flower P is lighter than the weight set by the second weighing means 30B, the inclined guide rail 22B to the upper guide rail 22C are indicated by the arrow N8.
Move to. Therefore, in the second recovery unit 13B, the length is long or medium, and the weight is medium (that is, long / medium weight and medium / medium).
(Nakaju) Flower PB is collected. That is, the second touch type sensor 12B and the second weighing means 30B are for selecting the second-class flower PB, and the flower P that is not satisfied by either one is as shown by arrows N7 and N8. , The third touch type sensor 12C for selecting the next third-class flower P and the third weighing means 30C.

The same operation is repeated thereafter, and the flower PC with medium or short length and light weight is collected in the third collecting section 13C. In addition, any of the collection units 13
The flower P that has not been collected by A, 13B, 13C is a flower that is extremely short or extremely light, and is collected by the fourth collection unit 13D (FIG. 1) as a defective flower PD. It As described above, this sorter performs sorting while gradually dropping the class into the first grade, the second grade, and the third grade.

As described above, only the long / heavy (that is, first grade) flower PA is collected in the first collecting portion 13A.
Further, only the long / medium weight and medium / medium weight (that is, second grade) flower PB is collected in the second collecting portion 13B. Further, only medium / light and short / light (that is, third grade) flower PCs are collected in the third collecting unit 13C.

Since the second collecting section 13B contains the long / medium heavy flower PB, this is the second collecting section 1B.
Remove from 3B and cut the stems and trim the length.
In addition, since the third collecting unit 13C contains medium / light flower PC, this is also taken out from the third collecting unit 13C and the stems are cut to make the lengths short. If the flower PA collected in the first collecting unit 13A also contains an abnormally long flower PA that is out of the standard, the stems are cut to make the length uniform.

Further, the sorting machine according to the present invention can be used in various ways. That is, for example, in FIG. 3, the switches of all the touch sensors 12A, 12B, 12C are turned off, or the levers 12a, 12b, 12 are turned on.
In order to prevent the length selection from functioning, for example, by removing c, the slider 16 is inevitably moved from the upper guide rail to the lower guide rail 21 as indicated by arrows N1, N5 and N8.
By shifting to A, 22A, and 23A, it is possible to perform only weight selection without performing length selection. Alternatively, in FIG. 3, before selecting the length of the flower P with the lever 12a of the most upstream touch-type sensor 12A, a non-standard flower P (for example, a flower having an excessive weight) is excluded in advance,
Only the flower P within the standard can be the target of the above-mentioned selection.

The present invention is not limited to the above-mentioned embodiment. For example, contrary to the above-mentioned embodiment, the upper guide rails 20, 21C, 22C are provided with weighing means 30A, 30.
B and 30C are provided, and the lower guide rails 21A, 22A,
23A may be provided with opening / closing sections 40A, 40B, 40C that operate by detecting the lengths of the touch sensors 12A, 12B, 12C, and the length may be detected after weighing with the weighing means 30A, 30B, 30C. It is a thing. Further, in the above embodiment, the case of selecting the first, second, and third classes has been described as an example, but the flower may be selected in any class. Further, although the above embodiment has been described by taking the case of selecting flowers as an example, the present invention is not limited to flowers and can also be applied to a bar-shaped agricultural product sorter such as burdock, dried radish, sweet potato, and cucumber.
