Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a agricultural product sorter, and more particularly to a means for accurately selecting large and small agricultural products, particularly small or spherical small agricultural products.

(Prior art) As a sorter for agricultural products such as mandarin oranges and apples, a plurality of drums with a large number of circular openings are arranged side by side, and while rotating these drums, the agricultural products put on it are It is known to sort large and small.

(Problems to be Solved by the Invention) However, since the above-mentioned conventional device sorts while rotating the drum, the agricultural products stuck in the openings formed in the drum during the sorting are not separated from the adjacent drums. There is a problem that the bridge is easily damaged by being bitten by the bridge plate arranged between them. Further, although the above-mentioned conventional apparatus is suitable for selection of relatively large agricultural products such as mandarin oranges and apples, there is a problem that it is difficult to apply to the selection of small agricultural products such as cherry tomatoes and plums.

Therefore, an object of the present invention is to provide an apparatus capable of accurately and smallly sorting agricultural products, particularly spherical or substantially spherical small agricultural products such as cherry tomatoes and plums, without damaging them.

(Means for Solving the Problem) For this purpose, the present invention uses a pair of left and right rollers 10a, 10b as a set of roller portions 10, and gradually increases the interval t from the upstream side to the downstream side. And a plurality of sliding members 6 are provided side by side and are slid from the upstream side to the downstream side on the roller portion 10 by being driven by the moving means 1 including the motor 5, and the upstream side of the roller portion 10 is provided. The agricultural products P supplied to the above are pushed down to the downstream side by the sliding member 6, and the agricultural products P are dropped from the interval t to be selected.

Further, the rollers 10a and 10b of the roller portion 10 are driven by the motors 14 and 18 so as to rotate in the direction of pushing up the agricultural product P located between the roller portions 10 and 10.

(Operation) In the above configuration, the agricultural product P supplied on the roller portion 10
Is driven to the downstream side by the sliding member 6 which is driven by the motor 5 and slides on the roller portion 10.
Are arranged side by side with the interval t gradually increasing from the upstream side to the downstream side, so that the agricultural products P are dropped and sorted downward from the interval t in order of relatively small size.

Further, by rotating the rollers 10a and 10b in the direction of pushing up the agricultural product P, the agricultural product P is rotated by the roller portion 10 and the roller portion 10.
You can prevent it from being forcibly pushed in between and being damaged.

(Embodiment 1) Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of the agricultural product sorter, in which reference numeral 1 denotes an endless belt conveyor, which is belted with pulleys 2 and 3. 5
Is a drive motor. On the surface of the endless belt conveyor 1, a plurality of brush bodies 6 serving as sliding members are provided at a pitch, and the brush bodies 6 rotate integrally with the conveyor 1. The shape and material of the sliding member can be freely set according to the agricultural products to be selected, especially small agricultural products, and for example, instead of the above brush body, a slightly elastic rubber sheet or the like can be used. You may use. Reference numeral 24 denotes a plate-shaped supply table for supplying the agricultural product P onto the conveyor 1, which is obliquely installed at a downward slope in the transport direction (a).

As shown in FIG. 1, the upper traveling portion of the conveyor 1 is a monitoring area E in which a worker removes defective products such as scratches from the conveyor 1 prior to size selection, and the lower traveling portion is an agricultural product P.
Is a sorting area F for sorting by size, and a chute 7 is provided at the end of the monitoring area E. In this way, the upper traveling part of the conveyor 1 is set to the monitoring area E.
This makes it easier to find defective products. On the upstream side of the selection area F, a plurality of brush rollers 8 driven by a motor (not shown) and rotated are arranged in parallel. Agricultural products P that have slid down the chute 7 and are supplied onto the brush rollers 8 are simultaneously swept away by the brush rollers 6 while being swept away by the brush bodies 6 toward the downstream side.

Reference numeral 10 denotes a pair of roller portions composed of a pair of right and left rollers 10a and 10b.
Adjacent to, gradually increasing the distance t from the upstream side to the downstream side.
(T1, t1, t2, t2 ... tn, tn) are enlarged and a plurality of them are arranged side by side, and the sliding members 6 are the endless belt conveyors 1.
Thus, it slides on the brush roller 8 and the roller portion 10 in parallel with them. That is, the endless belt conveyor 1 driven by the motor 5 serves as a moving unit that moves the sliding member 6 from the upstream side to the downstream side. Regarding the interval t, two parts having the same pitch are provided adjacent to each other in order to prevent selection omission (see also FIG. 2).

In FIG. 3, reference numeral 17 denotes an endless chain wound around one side of the roller 10a, which is driven by a motor 14 via a chain 15, a sprocket 16 coaxially mounted on the roller 10a, and the like. . Reference numeral 21 is an endless chain wound around the other side of the roller 10b, and is driven by a motor 18 via a chain 19, a sprocket 20 coaxially mounted on the roller 10b, and the like.

As shown in FIG. 4, each roller 10a rotates counterclockwise by driving the chain 17, and each roller 10b rotates clockwise by driving the chain 21. As described above, the rollers 10a and 10b are driven by the motors 14 and 18 to rotate in the direction in which the agricultural products P located between the roller portions 10 and 10 are pushed up.
This prevents the agricultural product P swept away by the force from being forcibly pushed into the space t between the roller portions 10 and damaged as shown by the chain line in FIG. Further, since the rotation of the agricultural product P itself is also prevented, it is possible to prevent the surface of the agricultural product P from being unnecessarily slidably contacting the rollers 10a and 10b and being damaged. Reference numeral 25 denotes a recovery unit composed of a box body arranged below the interval t, and recovers the agricultural products P of which size is selected (see FIGS. 1 and 2).

This sorter has the above-mentioned configuration, and the overall operation will be described below.

In FIG. 1, the agricultural product P is supplied from the supply table 24 onto the endless belt conveyor 1 and conveyed rightward. At this time, defective products such as scratches are removed from the line. When the other agricultural products P reach the end portion of the endless belt conveyor 1, they slide down the chute 7 and are supplied onto the brush roller 8. The agricultural product P supplied onto the brush roller 8 is washed away by the brush body 6 to the left.
Is polished by the brush roller 8 in a rotating state.
After that, the agricultural product P is further swept away by the brush body 6 and moves on the roller portion 10 toward the downstream side, and the roller portion 10 and the roller portion which are gradually set larger from the upstream side toward the downstream side.
From the intervals t1 to tn of 10, relatively small-sized ones are sorted in order of size, fall downward, and are collected by the collecting unit 25.

As described above, according to the present apparatus, it is possible to sort agricultural products, in particular, small-sized agricultural products having a spherical shape or a substantially spherical shape, in order from the smallest one with high accuracy and without damage.

(Embodiment 2) In FIG. 5, reference numeral 26 denotes an endless rotating chain, which is wound around sprockets 27 and 28. A plurality of brush bodies 6 are attached to the endless rotating chain 26 at a pitch. Has been done. Below the chain 26, a plurality of rollers 10 are arranged side by side, as in the first embodiment.
30 is arranged on the right side.

Agricultural product P supplied from the supply table 30 onto the roller unit 10
Is pushed down by the brush body 6 to the roller portion 10
While moving on the top, the smaller ones are dropped and sorted in order. Therefore, this is also similar to the first embodiment,
Agricultural products, especially spherical or nearly spherical small agricultural products, can be sorted according to size with high accuracy and without damage.

(Effect of the Invention) As described above, according to the present invention, it is possible to accurately select small and large agricultural products, particularly small or spherical spherical agricultural products. Further, since the rollers 10a and 10b of the roller unit 10 are driven by the motors 14 and 18 to rotate in the direction of pushing up the agricultural products P located between the roller units 10 and 10, the agricultural products P are It is possible to prevent the roller parts (10) from being forcibly pushed between the roller parts (10) and damaged.
