[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a sorting machine for agricultural products, and more particularly to a means for feeding agricultural products one by one to a holder for agricultural products provided in a sorting device.

(Prior Art) As a sorting machine for agricultural products, there is a known machine in which holders for agricultural products are arranged side by side on an endless conveyor, and the agricultural products are sorted while the holders are conveyed by the endless conveyor. Publication No. 60-7979).

(Problem to be solved by the invention) However, in the above-mentioned conventional method, the means for feeding agricultural products to the holder is a conveyor consisting of two rollers arranged in parallel, so the agricultural products are fed one by one to the holder. There was a problem in not being able to provide a good supply.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a sorting machine for agricultural products that is equipped with a feeding means that allows agricultural products to be easily fed one by one to a holder.

(Means for solving the problem) For this purpose, the present invention arranges the holding bodies 21 for agricultural products P in parallel on the endless conveyor 10 with a pitch T2,
A sorting device C that sorts the agricultural products P held on the holder 21 while conveying the holder 21 by the endless conveyor 10, and a supply device B that supplies the agricultural products P to the holder 21. In the sorting machine A, the feeding device B is constructed by arranging a plurality of supporting parts 5 for agricultural products in parallel on the endless conveyor 1 with a pitch T1 smaller than the pitch T2 of the holding body 21. The agricultural products P are transferred to the body 21.

(Function) According to the above configuration, when the agricultural products P are placed on the support section 5 conveyed to the endless conveyor 1, the agricultural products P are conveyed forward as they are, and are transferred from the support section 5 to the holding body 21 of the sorting device C. Transferred one by one.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of the agricultural product sorting machine, and FIG. 2 is a partial side view thereof. The supply device B is configured by arranging a large number of support parts 5 in parallel on which the agricultural products P are loaded one by one on the endless conveyor 1.
Reference numeral 6 denotes a delivery member for the agricultural products P provided in front of the conveyor 1, and when the support portion 5 rotates the conveyor 1, the agricultural products P are placed on this and thrown into the delivery member 6.

The sorting device C consists of an endless conveyor 10 made of an endless chain and a large number of sorting units 12 conveyed by this conveyor 10. 11 is a sprocket that drives the endless chain. As shown in FIG. 1, a plurality of sorting units 12 are arranged in a horizontal row in a direction perpendicular to the conveying direction N, and the sorting units 12, 12, . . . The holding body for the produced produce is adapted to expand at the same time.

3 and 4 are a sectional view and a plan view of the sorting unit 12, which consists of a rectangular plate-shaped base material 20 attached to the conveyor 10, and a base material 20 on this base material 20. It consists of a bowl-shaped agricultural product holder 21 and a donut plate-shaped rotating body 22. The holding body 21 is made up of a plurality of (six in this embodiment) expansion/contraction pieces 21a, the center of which is a sorting hole 19. An extension portion 21b extending horizontally outward is provided at the lower end of the expansion/contraction piece 21a. This extending portion 21b
is slidably attached to a guide member 23 provided radially on the base material 20, and as will be described in detail later, the extending portion 21b is guided by this guide member 23 and slides in the radial direction. As a result, the expansion/contraction piece 21a expands/contracts.

The rotating body 22 has a guide portion 2 consisting of an arc-shaped long hole.
Six guide members 4 are formed at regular intervals, and a guided member 25, which is provided in a rib shape and projects from the extending portion 21b, is fitted into the guide portion 24. 26 are rollers provided at the four corners of the base material 20,
The outer peripheral edge of the rotating body 22 contacts these rollers 26 and rotates horizontally. 30 is a protrusion extending from the rotating body 22, and a rod-shaped interlocking member 31 is pivotally attached to the tip thereof. 35 is a spring material for supporting the rotating body 22; The interlocking member 31 connects the rotating bodies 22 of the sorting units 12 in a horizontal row (see also FIG. 1). In FIG. 4, an arm 32 is connected to the interlocking member 31 at the side end, and a roller 33 is pivotally attached to the tip of the arm 32. Also, along the conveyor 10, the guide section 34
(341 to 345) are arranged in parallel (see FIG. 1), and the roller 33 slides along the guide portions 341 to 345. The guide parts 341 to 345 are
The roller 33 is gradually displaced toward the center from the upstream side to the downstream side, and the roller 33
, the rotating body 22 resists the spring force of the spring member 35 and horizontally rotates in the counterclockwise direction Q in FIG.
4 and move outward A, each expansion/contraction piece 21a
expands.

Reference numerals 37 and 37 are scooping members erected at the rear of the base plate 20, and when the sorting unit 12 rotates the sprocket 11 and moves from the lower transition part to the upper transition part of the conveyor 10, the above-mentioned When the agricultural products P on the delivery member 6 are scooped up and the sorting unit 12 moves to the upper transition section, the agricultural products P are
is put into the holding body 21.

As shown in FIG.
1 is considerably smaller than the juxtaposed pitch T2 of the holder 21.

This agricultural product sorting machine has the above-mentioned configuration, and its operation will be explained next.

In FIG. 2, agricultural products P placed on the support section 5 of the supply device B are transferred to the delivery member 6, scooped up by a scooping material 37, and thrown into the holder 21. The sorting unit 12 is conveyed by the conveyor 10 and conveyed to the left in FIG. 1, while the roller 33 at the tip of the arm 32 slides along the guide portion 34. The roller 33 moves from the first guide section 341 to the second guide section 34
2, the arm 32 rotates slightly counterclockwise in FIG. 4, and the interlocking member 31 moves from the solid line position to the chain line position in the same figure. Then, the rotating body 22 horizontally rotates in the counterclockwise direction Q against the spring force of the spring material 35, and the guided part 25 moves into the guiding part 24.
By sliding the expansion/contraction piece 2 outward along
1a expands outward, the sorting hole 19 expands, and agricultural products P smaller than its diameter fall downward. In this case, since the horizontally arranged rotating bodies 22, 22... are connected by the interlocking member 31, each rotating body 2
2, 22, . . . rotate horizontally at the same time, and therefore, the respective holders 21, 21, . After that, the roller 33 moves to each guide portion 343~
345, the holding body 21 gradually expands in the same manner and falls downward one after another starting with the small agricultural product P.

By the way, it is conceivable that the feeder B be removed and the agricultural product sorter be configured only by the sorter C. In this case, the operator
The user stands at the starting end of the holder 21 and puts the agricultural products P into the holder 21 one by one. However, in this case, if the input of agricultural products P into the holding body 21 is delayed,
The holder 21 moves forward, and the agricultural products P cannot be thrown into the holder 21 even if the user extends his arm. Alternatively, if the input of agricultural products P into the holder 21 is delayed, when the agricultural products P are input into the holder 21, the holder 21 is placed at the first sorting point (in the case of this embodiment, in FIG. 1, the guide portion 341 This means that they have already passed the point where the Therefore, in order to prevent such inconvenience from occurring, the operator should always be near the starting end of the sorting device C, and ensure that the holder 21 is not connected to the sprocket 1.
1 and move to the upper transition part, and when it moves to the upper transition part, quickly move the agricultural product P to the holder 2 without missing the timing.
1, and the workers are forced to work long and harsh hours.

On the other hand, if the feeding device B is arranged as described above, the worker can appropriately load the agricultural products P onto the support section 5 while the support section 5 is moving through the upper transition section of the conveyor 1. Once loaded, the agricultural products P can be automatically put into the holder 21 of the sorting device C one by one. That is, in FIG. 2, three supporting parts 5 are present in a horizontal position at the upper transition part of the conveyor 1, but the operator can move them regardless of the feeding timing of the holding body 21 of the sorting device C. Once the agricultural products P are placed on these supports 5, they are automatically transferred one by one from the supports 5 to the holder 21. Therefore, for example, if the worker places the agricultural products P on three supporting parts 5 at the same time, the time it takes for the subsequent supporting parts 5 to move from the lower transition part to the upper transition part will be shorter than the eye from the feeding device B. It is okay to let go or rest your hand. Moreover, since the pitch T1 of the support part 5 is considerably smaller than the pitch T2 of the holder 21, it is easier to perform each operation by simply extending your arm a little compared to the case where the agricultural products P are directly put into the holder 21. Agricultural products P can be placed on the support part 5. By providing the above-mentioned feeding device B in this manner, the worker can carry out the work of supplying the agricultural products P while taking appropriate breaks between works, and therefore the work of supplying the agricultural products is extremely easy. It will be light work.

(Effects of the Invention) As explained above, according to the present invention, the agricultural products P can be supplied one by one to the holding body 21 of the sorting device C from the feeding device B. Moreover, the worker
Regardless of the feeding timing of the holding body 21 of the sorting device C, it is only necessary to place the agricultural products P on the support section 5 that is conveyed to the endless conveyor 1 of the feeding device B, and in that case, the agricultural products P can be supported by just slightly extending the arm. Since the agricultural products P can be placed on the section 5, the work of supplying the agricultural products P becomes extremely easy and light work, and the worker can carry out the work while taking appropriate breaks.
