Description

[Detailed Description of the Invention] The present invention automatically sorts agricultural products having a relatively long and narrow length such as cut flowers, burdock, and cucumbers by size, length, thickness, etc., and sorts and stores them into predetermined stockers. This invention relates to a sorting device for an automatic agricultural product sorting machine.

Conventionally, various sorting devices have been disclosed that automatically sort agricultural products, particularly cut flowers, by length, size, etc.

Among these, for example, an automatic sorting machine by the present inventor as shown in Japanese Patent Application No. 53-33328 has been filed and disclosed, but in the present invention, such an automatic sorting machine for agricultural products is capable of sorting. It is an object of the present invention to provide a sorting device for an automatic agricultural product sorting machine that is further simplified, reduces manufacturing costs, and enables reliable sorting with fewer failures during use.

Hereinafter, the details of the sorting device of the automatic agricultural product sorting machine of the present invention will be further illustrated and explained.

FIG. 1 is a schematic explanatory diagram for explaining the sorting device of the automatic agricultural product sorting machine according to the present invention, and what is shown as 1 in the figure is a storage section for storing the sorted agricultural products of the present sorting device. The storage section 1 is constructed by arranging a plurality of upwardly opening stockers 2 in parallel, and above each stocker 2 there are three stockers 2.
A conveying means having a sorting function is provided.

The conveying means 3 having the sorting function is a device for sorting each agricultural product according to its size, length, thickness, etc., and also has a conveying function.

The illustration shows an example of such a sorting device, in which a sheet-like material 5 formed of a sheet, net, string, etc. is stretched endlessly around at least two shafts 4, 4, and is moved. A unit conveyor 6, which is capable of moving one shaft 4 in relation to the means 8 to shorten the distance between the shafts 4, 4, is placed above each stocker 2 and straddles the adjacent stockers 2, 2. It has a facing positional relationship, that is, a positional relationship that has an input end that allows sorted agricultural products to be input into the upper opening of the stocker 2, and a gap between it and the adjacent unit conveyor 6 that is not obstructed when rotating. At least the same number of transport means 3 as the stockers 2 are provided in terms of position.

In addition, the purpose can be achieved if there is a gap of at least 1 mm that does not impede the rotation of each of the unit conveyors 6.

Here, one shaft 4 of a predetermined unit conveyor 6 is moved to shorten the distance between the shafts 4, 4, and the distance between one shaft 4 of the unit conveyor 6 and the other unit conveyor 6 facing the unit conveyor 6 is reduced. A chute space 7 is formed in order to put the sorted agricultural products into a predetermined stocker 2.

That is, this conveyance means 3 has a conveyance function and at the same time has a sorting function as mentioned above, and the sorting is measured by a measuring device shown as 9 in the figure, and each one is controlled by a control device shown as 10. The conveying means 3 performs its respective functions so that the sorted materials can be placed into predetermined stockers 2 set for each type.

In addition, the conveying means 3 first carries each agricultural product supplied to the automatic agricultural product sorting machine as described above onto the conveying means 3 connected to the measuring device 9, and there measures the size, length, thickness, etc. The respective types are stored, and a command is given from the control device 10 to the transport means 3 above each stocker 2 so that the transport means 3 performs a predetermined operation.

The control mechanism related to these can be any other conventional general control mechanism and has no special features, so a detailed explanation will be omitted here.

The conveying means 3 shown in FIG.
Agricultural products are fed from the left side in the figure on each unit conveyor 6 around which a sheet-like material 5 is stretched, and in the process of sequentially moving on each unit conveyor 6, the agricultural products are sorted and placed above a predetermined stocker 2. When positioned, each unit conveyor 6 forms a chute space 7 to the stocker 2 between the adjacent front unit conveyor 6, that is, the right side unit conveyor 6 in FIG. Each agricultural product is sorted and stored in each stocker 2.

Various types of moving means 8 can be considered to form the space 7 for chute of agricultural products between adjacent unit conveyors 6, and the moving means 8 described in this embodiment is a typical example thereof. There is.

FIG. 2 shows how a chute space 7 is formed between such a unit conveyor 6 and another adjacent unit conveyor 6. In order to shorten the distance between the shafts 4 and 4, the rear shaft 4 is moved downward about a fulcrum provided approximately in the center between the shafts 4 and 4, and the space between the front unit conveyor 6 and the rear unit conveyor 6 is moved. The chute space 7 is formed in the
B is the opposite of A, and C is the opposite of A, and instead of moving one shaft 4 downward as in A to shorten the distance between the two shafts 4, 4, it is moved at the rear of the front unit conveyor 6. In each case, the shaft 4 is moved forward to contract the sheet-like material.

That is, the method of forming the chute space 7 between the unit conveyor 6 carrying the sorted agricultural products and the next adjacent unit conveyor 6 in the present invention is as shown in FIG. Since a chute space 7 is formed between each unit conveyor 6 and another adjacent unit conveyor 6 above the predetermined stocker 2 into which the agricultural products are to be input, the agricultural products are input into the respective stockers 2. .

Here, an example of a specific method for the moving means 8 is illustrated in FIG.

FIG. 3 shows an embodiment for implementing the principle of A and B in FIG. 2, in which a sheet-like material 5a is stretched endlessly around two shafts 4a and 4b, and By associating the motor 11 and rotating the front shaft 4a, the sheet-like material 5 is
A is made endlessly rotatable, a fixed shaft 15 is located in the middle of the sheet-like object 5a, and an operating rod 16 is fixedly extended from the rear shaft 4b to the front shaft 4a side, and the end of the operating rod 16 is An endless sheet-like object 5a
A cylinder 18 or a rack and pinion device (not shown) is provided at the end of the rotary rod 17 to rotate the rotary rod 17.

Therefore, by rotating the rotating rod 17, the operating rod 16 fixed thereto moves the rear shaft 4b downward.

At this time, the unit conveyor 6 uses the rotating rod 17 or the fixed shaft 15 located in the endless sheet-like material 5a as a fulcrum, and shortens the distance between its shafts 4a and 4b, as shown by the imaginary line in the figure. A chute space 7 is formed between the rear unit conveyor 6 (not shown) and a rear unit conveyor 6 (not shown).

Furthermore, although each form of the chute space 7 shown in FIG. It suffices to move only a part of the feeder by a certain angle, which has a simple structure, and also allows the agricultural products placed on the rear unit conveyor 6 to be reliably fed into the predetermined stocker 2.

Further, in this embodiment, only a part of the unit conveyor 6 is moved, so not only can the moving means 8 be used even if the power is small, but it also does not require much space for movement. be.

Furthermore, the one indicated by B is similar in principle to A and reliably forms the chute space 7, but
If such a form of the chute space 7 is adopted, the unit conveyor 6 on which the agricultural products are placed is tilted and lowered toward the inside of the stocker 2, so that the agricultural products placed on the unit conveyor 6 are moved into the stocker 2. The input height is reduced, and damage to agricultural products during sorting can be reduced.

Therefore, in the method shown in B, by adjusting the angle of inclination, it is possible to sort and feed agricultural products into the stocker 2 without damaging the agricultural products.

Furthermore, in the method of forming the chute space 7 shown in FIG. 2C, such a mechanism can be achieved by using an elastic material for the sheet-like material, but aging of the sheet-like material over time is a problem. As long as the material is selected to the extent that it does not, instead of the moving means 8 as shown in FIG. This can be achieved simply by providing a pushing means for causing the movement.

In addition, the method for forming the chute space 7 is not limited to each individual method, but a combination of a plurality of methods may be employed as appropriate.

In the sorting device of the automatic agricultural product sorting machine according to the present invention as described above, each unit conveyor 6 and other adjacent unit conveyors 6 and shute the agricultural products whose size, length, thickness, etc. have been sorted by a measuring device or the like. By simply forming the storage space 7, the agricultural products can be sorted and stored in each stocker 2, and this unit conveyor 6 simply conveys the agricultural products to the upper part of the storage section 1 consisting of a large number of stockers 2 arranged side by side. Instead, each conveyor 6 also has the function of sorting the sorted agricultural products, simplifying the device, and each unit conveyor 6 simply stretches the sheet-like materials 5 around the two shafts 4, By simply providing a moving means 8 for rotating and simultaneously forming a chute space 7 between adjacent unit conveyors 6, conveyance and sorting can be carried out, so the manufacturing cost is low, and such a Due to its structure, the device is easy to manufacture, has few failures, and can be reliably sorted.
