Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tray for loading and transporting agricultural products in an agricultural product sorting apparatus for sorting agricultural products such as tomatoes, peaches, pears, apples, melons, and rice cakes.
[0002]
[Prior art]
2. Description of the Related Art There is provided a type of agricultural product sorting apparatus that transports agricultural products one by one on a receiving tray, and measures and sorts agricultural products on the receiving tray with a measuring unit arranged in the middle of the transportation. As a saucer used in such an agricultural product sorter, many things are proposed according to various purposes.
[0003]
As one of the conventional trays, it is formed in a mortar shape having an inclined surface whose inner diameter gradually decreases toward the bottom, which is made of a flexible elastic material on which agricultural products placed inside the tray body are placed. ) In which the sloped surface is inflated inwardly to form a morning glory type or a trumpet type, and when the agricultural product is placed in the container, the swelled portion is moderately formed by the weight of the agricultural product. By flexing, the contact area with the inclined surface is increased and the fit is improved to prevent the swinging movement of agricultural products (for example, see Patent Document 1).
[0004]
As another conventional saucer, there has been proposed one in which a plurality of fin-like elastic projections having flexibility are formed in the horizontal direction on the inclined surface of a mortar-shaped receiving part formed on the inner periphery of the saucer body. And when the agricultural product is placed on the receiving portion, the plurality of fin-like elastic projections bend so that the tip ends hang downward along the surface shape of the agricultural product placed on the receiving portion. The agricultural product is stably placed by contacting and pressing and supporting the agricultural product on the side surfaces of the plurality of fin-like elastic protrusions (see, for example, Patent Document 2).
[0005]
All of the conventional saucers described above are formed in a mortar shape on which the agricultural products are placed, so that a single saucer can be used to produce agricultural products such as fruits with large outer diameters such as potatoes and agricultural products with small outer diameters such as tomatoes. The saucer described in Patent Document 1 is closed at the bottom of the saucer, so that, for example, the agricultural products are illuminated from the outside, and the transmitted light is photographed with a camera, for example, sugar content. It cannot be used for an agricultural product sorting apparatus equipped with a measuring device that measures the amount of food.
[0006]
Moreover, in the saucer of patent document 2, the ground contact height of the agricultural product with respect to a mounting part falls, so that an agricultural product becomes small, as a result, the upper part of a small diameter agricultural product protrudes slightly from the upper edge of a saucer, or a saucer. The position is lower than the upper edge of the field, and the agricultural products cannot be illuminated with a sufficient amount of light, and transmitted light cannot be photographed.
[0007]
Then, the following things are proposed as a saucer corresponding to the recent agricultural product sorter which uses the transmitted light measuring device as the sorting element and uses the internal quality of the produce.
[0008]
As one of the conventional saucers capable of measuring transmitted light, it has a through hole for measuring transmitted light and has a slope inclined downward toward the through hole around the through hole. A receiving seat disposed inside the saucer body and an elastic support member having an elastic fin-like piece that supports the side of the produce are provided on the upper edge of the saucer body facing the front and rear in the transport direction, and The thing of the structure which provided the elastic protrusion formed in the fin shape which has many flexibility on the slope is proposed. And for small-diameter agricultural products, it is possible to secure the light shielding performance during the measurement of transmitted light by the receiving seat and the elastic projection of the receiving seat, and to prevent the posture change during transportation.
[0009]
In addition, for a medium-diameter agricultural product, it is placed at the seat, and the upper end of the upper elastic support member is formed by the outer peripheral surface of the agricultural product among the upper and lower elastic support members. While being pushed and bent downward, it is expanded outward in the radial direction, so that the tip of the upper elastic support member abuts elastically to prevent a change in posture during conveyance.
[0010]
Furthermore, for large-diameter agricultural products, they are placed at the seats and supported with the elastic deformation of the elastic support members having two upper and lower tiers, and prevent posture changes during transportation. (Patent Document 3).

[0012]
[Problems to be solved by the invention]
The saucer described in Patent Document 3 described above can be placed stably by a large number of flexible fin-shaped elastic protrusions formed on the slope of the seat even for agricultural products having different sizes in outer diameter. In the measurement of transmitted light, there is an excellent effect that a sufficient light shielding property against disturbance light can be obtained.
[0013]
By the way, when the agricultural product is placed on the receiving tray, if the gravity center of the agricultural product is at a high position, the stability at the time of transportation deteriorates. Therefore, the seat is preferably as low as possible.
[0014]
However, in the case of agricultural products of small or medium diameter, there are few parts that sink completely in the saucer or are exposed upward from the upper end of the saucer. Therefore, the left and right outer peripheries of the upper part of the saucer are notched greatly so that the illumination light from the light source can be sufficiently applied to the produce, but the shape of the saucer is complicated.
[0015]
On the other hand, even when a small-diameter agricultural product is placed on the receiving seat, the horizontal length of the upper elastic supporting member is increased or the receiving portion is extended so that the elastic supporting member can support the agricultural product in the horizontal direction as much as possible. The distance in the vertical direction between the seat and the upper elastic support member is shortened, but this also has a limit. In this way, when trying to support and stabilize a small-diameter agricultural product, when a large-diameter agricultural product is placed on a tray, the position where the upper elastic support member abuts against the agricultural product is supported at the bottom of the agricultural product. It is considered that the position is likely to be close and the agricultural product during the transportation by the elastic support member cannot be sufficiently supported.
[0016]
In addition, in order to irradiate the agricultural product with the irradiation light from the light source from the direction orthogonal to the conveying direction, the elastic support member is provided back and forth along the conveying direction, and thus the agricultural product swings in the direction orthogonal to the conveying direction. It is also conceivable that prevention cannot be performed sufficiently.
[0017]
Furthermore, in order to align the direction of the saucer in the direction in which the irradiation light is not blocked as described above when measuring the transmitted light, it is necessary to devise both the saucer and the agricultural product sorting device to align the orientation of the saucer. .
[0018]
The object of the present invention has been made in view of such conventional problems, and an object of the present invention is to provide a tray for an agricultural product sorting apparatus capable of stably placing agricultural products of various sizes.
[0019]
It is another object of the present invention to provide a tray for an agricultural product sorting apparatus that is excellent in light shielding properties and can prevent the incidence of ambient light while ensuring the stability of placing agricultural products.
[0020]
[Means for Solving the Problems]
  As for 1st invention, in the saucer for agricultural product sorting apparatuses with which agricultural products are mounted and conveyed along the conveyance path of agricultural products sorting device as described in claim 1,
  A cylindrical saucer body with an open top;
  A receiving member forming a mounting surface of the agricultural product disposed in the tray body;
  A first produce anti-sway member that is formed in a flat plate shape by an elastic member such as rubber that can be flexibly elastically deformed, and that is disposed at the top of the saucer body having a first opening at the center;
  It is formed in a flat plate shape by an elastic member such as rubber that can be flexibly elastically deformed, and has a second opening having a smaller diameter than the first opening at the center.And in the vertical directionThe receiving memberAnd the first agricultural product anti-sway memberA second agricultural product anti-sway member disposed on the

A cylindrical body,
Have
  In a size in which the agricultural product is not larger than the predetermined weight and the second opening is expanded and placed on the receiving member, the second agricultural product anti-sway member is a flexible member formed by the expansion of the second opening. By elastically supporting the outer periphery of the agricultural product over the entire circumference elastically from the side,
  When the agricultural product is larger than the predetermined weight and the first opening is expanded and placed on the receiving member, the second agricultural product anti-sway member moves downward due to the shrinkage of the cylindrical body and The first agricultural product anti-sway member is deformed flexibly and elastically in accordance with the contact surface with the agricultural product, and the outer periphery of the agricultural product is located on the substantially entire circumference side by the flexible elastic deformation generated by the expansion of the first opening. More elastic thanIt is characterized by supporting.
[0021]
  In the first invention, if the agricultural product to be placed on the tray is a small diameter, the second agricultural product anti-sway member is flexibly elastically deformed and placed on the receiving member. At that time, the second agricultural product dedicated to the small-diameter agricultural product is shaken. The stop member prevents the small-diameter agricultural product from shaking. This second agricultural product anti-sway memberPerimeterIs supported from the side over substantially the entire circumference, so that in the agricultural product sorting apparatus, the posture of the agricultural product can be conveyed on the saucer without changing or falling down due to vibration or the like.
[0022]
In addition, even if the small-diameter agricultural product is placed on the receiving member, the receiving member itself does not sink downward, and the distance between the receiving member and the upper surface of the receiving tray is such that the upper part of the small-diameter agricultural product is exposed, When the measuring device provided in the agricultural product sorting device is a transmitted light measuring device, it is possible to sufficiently irradiate the agricultural product with illumination light from the light source with the agricultural product placed on the receiving member.
[0023]
  Furthermore, when the produce to be placed on the saucer has a medium diameter or more, the produce is placed on the receiving member by moving the cylindrical body downward while flexibly elastically deforming the second produce-stabilizing member. The agricultural product swinging member will not get in the way. At that time, the first agricultural product anti-sway memberAroundIt is supported from the side over almost the entire circumference.
[0024]
  In addition, both the first agricultural product anti-sway member and the second agricultural product anti-sway member arePerimeterIs supported from the side over substantially the entire circumference, so that the mounting direction of the tray is not limited with respect to the agricultural product sorting device.
[0025]
In this way, regardless of the size of the agricultural product (weight according to the size), the agricultural product to be placed can be stably supported and transported only by placing the agricultural product on the tray.
[0026]
  According to a second aspect of the present invention, as described in the second aspect, in the first aspect described above, the cylindrical body integrally includes the receiving member,More than the predetermined weightWhen the agricultural product is placed, the receiving member also moves downward as the cylindrical body contracts.

According to the second invention, since the receiving member and the second agricultural product shaking preventing member are integrally provided in the cylindrical body, the number of parts of the receiving tray can be reduced, and the structure of the receiving tray can be further simplified. it can.
[0028]
Further, when a heavy agricultural product is placed, the receiving member sinks, so that the gravity center position of the heavy (large diameter) agricultural product is lowered, and the large diameter (heavy) agricultural product can be placed more stably.
[0029]
A third invention is the above-described first invention, wherein the cylindrical body and the receiving member are separate structures.
[0030]
In the third invention, the role of the receiving member and the role of the cylindrical body can be separated, the structure of the receiving member and the cylindrical body can be simplified, and the design of the receiving member and the cylindrical body can be simplified. More freedom.
[0031]
According to a fourth aspect of the present invention, as described in the fourth aspect, in any one of the above-described aspects, the receiving member is formed with a through hole for transmitted light measurement.
[0032]
In 4th invention, when the transmitted light measuring device is used as a measuring device of the agricultural product sorting device, when the agricultural product placed on the receiving tray is irradiated with illumination light from the upper side, the transmitted light measuring penetration provided in the receiving member The transmitted light is emitted from the hole, and the transmitted light is received by the light receiving means, whereby the sugar content, maturity, etc. of the agricultural product can be measured.
[0033]
According to a fifth aspect of the present invention, as described in the fifth aspect, in any one of the above-described inventions, the receiving member and the cylindrical body have a light shielding property.
[0034]
In the fifth invention, when the transmitted light measuring device is used as the measuring device of the agricultural product sorting device, disturbance light does not enter the transmitted light emitted from the agricultural product, so the sugar content, maturity, etc. of the agricultural product can be accurately determined. It can be measured.
[0035]
A sixth invention is any one of the above inventions, wherein the cylindrical body is formed in a bellows structure.
[0036]
In the sixth invention, since the cylindrical body has a bellows structure, the spring constant when the cylindrical body is elastically expanded and contracted in the vertical direction can be easily managed, and the expansion and contraction of the cylindrical body is permitted. Can be obtained.
[0037]
The seventh invention is the sixth invention as described in the seventh aspect, wherein the vertical deformation stress in the bellows-structured tubular body is greater than the bending stress of the second produce stabilization member. Is also large.
[0038]
In the seventh invention, when a heavy agricultural product is placed on the second agricultural product stabilizing member, the cylindrical product is deformed while flexibly elastically deforming the second agricultural product stabilizing member until the agricultural product is placed on the receiving member. Since it shrinks, when placing a heavy agricultural product having a medium diameter or larger on the receiving tray, the second agricultural product anti-sway member and the cylindrical body do not get in the way even when the agricultural product is placed on the receiving member.

[0041]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the drawings.
(First embodiment)
1 to 4 show a first embodiment of the present invention. 1 is a longitudinal sectional view of the saucer, FIG. 2 is a top view of FIG. 1, FIG. 3 is a longitudinal sectional view showing a state where a small-diameter agricultural product is placed on the saucer of FIG. 1, and FIG. It is a longitudinal cross-sectional view which shows the state which mounted the agricultural product.
[0042]
In FIG. 1, the saucer 1 of the present embodiment includes a cylindrical saucer body 2 in which a hole 2 a suitable for transmitted light measurement is formed at the center of the bottom wall part, and an outer peripheral wall part 2 b of the saucer body 2. The disc-shaped produce anti-swaying member 3 that is sandwiched and held at the upper edge and opened at the center, and the produce that is sandwiched and held at the inner periphery of the center hole 2a of the tray body 2 are As shown in FIG. 1, the receiving seat 4 is formed with a hole portion 4a for measuring transmitted light coaxially with the axis of the hole portion 2a of the saucer body 2 as shown in FIG. ing.
[0043]
The saucer body 2 is formed of an opaque resin material, and the upper end of the outer peripheral wall 2b is aligned at the same height. Around the hole 2a of the tray body 2, a flange-shaped mounting seat 2c to which the lower portion of the seat 4 is attached is formed. The tray body 2 is formed by combining a plurality of members. However, the combination of these members is not particularly related to the present invention, so that it is illustrated as a single member and the description thereof is omitted. To do. Of course, it may be formed by one member by an injection molding method or the like.
[0044]
In addition, since the classification of the agricultural products as a result of measurement by the measuring device is managed by the computer for each agricultural product, the outer peripheral wall portion 2b of the receiving tray body 2 is obtained in order to obtain specific information about the receiving tray on which the agricultural products are placed. A bar code or a magnetic recording portion is formed on the outer surface of the substrate, and a microchip or the like is embedded therein.
[0045]
Furthermore, the saucer body 2 is made opaque so that external disturbance light is shielded so as not to affect the measurement transmitted light emitted from the agricultural products placed on the saucer 1.
[0046]
The agricultural product anti-sway member 3 is made of an elastic material such as rubber that can be flexibly elastically deformed. As shown in FIG. 2, four pieces are provided at regular intervals from the opening 3a formed in the central portion toward the outside in the radial direction. Slits 3b are formed, and support pieces 3c are formed between the slits 3b. Each support piece 3c is substantially horizontal on the back surface side, inclined on the front surface side toward the inner peripheral side, and gradually decreases in thickness toward the inner peripheral side.
[0047]
In the present embodiment, it is assumed that the agricultural product anti-sway member 3 performs anti-swaying on the agricultural product A1 having a large outer diameter from the agricultural product A2 having a medium outer diameter (for example, L-sized melon) A2. In the agricultural product A2 having a medium outer diameter, it is curved so as to push the tip of the support piece 3c downward, and for the agricultural product A1 having a large outer diameter, it is generally downward from the root side. The support pieces 3c are easily elastically deformed by providing the slits 3b. And the four support pieces 3c which elastically deformed contact | abut to the perimeter of an agricultural product, and apply substantially equal pressing force toward the center side, and an agricultural product is supported. At that time, a large pressing force is applied to the large-diameter agricultural product A1, a weak pressing force is applied to the medium-diameter agricultural product, and sufficient horizontal direction is applied to the heavy (large-diameter) agricultural product. Holding power is obtained.
[0048]
Further, a concave groove 3 d is formed along the circumferential direction on the outer peripheral portion of the agricultural product steadying member 3, and the concave groove 3 d is sandwiched and fixed by the upper edge portion of the outer peripheral wall portion 2 b of the tray body 2. .
[0049]
In addition, although the agricultural product steadying member 3 divides the disk portion into four support pieces 3c by four slits 3b, the number of divisions is not limited to this, and is divided into three, five or more. However, if the number of divisions increases too much, the pressing force per support piece is reduced, and the holding power of agricultural products is reduced. Therefore, about 3 to 6 pieces are desirable.
[0050]
The receiving seat 4 has a cylindrical body 4b that is formed in a bellows shape and can be vertically expanded and contracted, and a disk-shaped receiving member 4c that forms a flat placement surface for agricultural products is integrally formed in the cylindrical body 4b. Is formed. In addition, a disc-shaped small-diameter agricultural product rocking-preventing member 4d having an open central portion is integrally formed at the uppermost portion of the cylindrical body 4b. The seat 4 of the present embodiment is composed of an elastic member such as opaque rubber.
[0051]
The cylindrical body 4b has a configuration in which six indirect portions for expanding and contracting in the vertical direction are provided, and a receiving member 4c is provided in the third indirect portion from the bottom. Since the receiving member 4c is formed in a disk shape extending in the center direction from the inner periphery of the cylindrical body 4b, the load of the agricultural product placed on the receiving member 4c is the third point from the bottom of the cylindrical body 4b. Since it does not have a structure in which slits are formed in the radial direction from the central opening as in the agricultural product anti-sway member 3, the strength in the receiving member 4c itself and the cylindrical body 4b itself are added to the entire circumference of the indirect part evenly. By taking into account the strength in the above, even if the agricultural product is placed on the receiving member 4c, the receiving member 4c is not greatly bent and the placing of the agricultural product is not disabled. However, in the present embodiment, by reducing the thickness of the inner peripheral portion 4e of the receiving member 4c, flexible elastic deformation caused by rubber is caused by the load of the agricultural product to be mounted, thereby achieving mounting stability.
[0052]
On the other hand, the cylindrical body 4b of the receiving seat 4 is set to a spring constant such that the lower indirect portion is bent from the receiving member 4c and the cylindrical body 4b is contracted to the extent that the small-diameter (light) agricultural product A3 is placed. The height of the receiving member 4c is hardly changed from the height of the agricultural product in the non-mounting state.
[0053]
For this reason, the upper part of the small-diameter agricultural product placed on the receiving member 4c protrudes above the agricultural product anti-swaying member 3 fixed to the upper part of the outer peripheral wall 2b of the receiving tray body 2, and is transported by the agricultural product sorting device. In the measurement part in the conveyor, the irradiation light emitted from the light source arranged on the side perpendicular to the conveying direction is sufficiently irradiated to the agricultural products.
[0054]
Further, even when the medium-diameter agricultural product A2 is placed, the spring constant of the cylindrical body 4b is such that the height of the receiving member 4c is hardly changed from the height of the agricultural product in the non-placing state, similarly to the small-diameter agricultural product. Is set. In this case, as shown in FIG. 1, the medium-diameter agricultural product A2 is elastically held by the four support pieces 3c so that the tip end side of the support piece 3c of the produce-stabilizing member 3 is bent downward. However, since the center position of the medium-diameter produce A2 in the mounted state is not so high, the support piece 3c of the produce-stabilizing member 3 is sufficiently held in the horizontal direction (the tray conveying direction in the produce sorting device). .
[0055]
Furthermore, when the large-diameter (heavy) agricultural product A1 is placed on the tubular body 4b of the seat 4, the indirect part of the bellows is bent and the tubular body 4b is generally contracted downward. The spring constant is set, and the height of the receiving member 4c is lower than the height of the agricultural product in the non-mounting state, and the center of the large-diameter agricultural product A1 is lowered to improve the mounting stability. The horizontal support stability by the support piece 3c of the anti-sway member 3 is also improved.
[0056]
As described above, the horizontal shaking for the agricultural products having a medium diameter or larger is performed by the agricultural produce rocking member 3 provided at the upper end of the outer peripheral wall 2b of the saucer body 2 separately from the receiving seat 4. However, the small-diameter agricultural product A3 is prevented from shaking in the horizontal direction by the small-diameter agricultural product rocking-preventing member 4d provided on the upper portion of the cylindrical body 4b. When the small-diameter agricultural product A3 is placed on the receiving member 4c of the cylindrical body 4b, the small-diameter agricultural product rocking | fluctuation prevention is carried out so that the opening 4f formed in the center of the small-diameter agricultural product rocking | fluctuation-preventing member 4d with the dead weight of the small-diameter agricultural product A3 may expand. The member 4d needs to be elastically deformed flexibly.
[0057]
Therefore, in the present embodiment, the slits 4g are formed at equal intervals from the opening 4f of the small-diameter agricultural product swaying member 4d to the outer side in the radial direction, and the small-diameter agricultural product support pieces 4h are formed between the slits 4g. Thus, each small-diameter agricultural product support piece 4h is flexibly elastically deformed downward so that the opening 4f can be expanded, and the thickness of the small-diameter agricultural product anti-sway member 4d is gradually reduced from the outer peripheral side toward the inner peripheral side. Thus, the bending strength of the small-diameter agricultural product support piece 4h is made weaker than the expansion / contraction deformation strength of the cylindrical body 4b of the seat 4.
[0058]
Therefore, when the small-diameter agricultural product A3 is placed on the receiving seat 4, the four small-diameter agricultural product support pieces 4h constituting the small-diameter agricultural product rocking member 4d of the cylindrical body 4b are bent and deformed downward by the weight of the small-diameter agricultural product A3. Then, the opening 4f is expanded, and the small-diameter agricultural product A3 is placed on the receiving member 4c without contracting the cylindrical body 4b. The small-diameter agricultural product A3 is supported by the four small-diameter agricultural product support pieces 4h that flexibly and elastically deform downward.
[0059]
Next, a case where agricultural products are placed on the saucer having the above-described configuration will be described.
[0060]
When the produce placed on the saucer 1 has a small diameter as shown in FIG. 3, the small-diameter produce A3 pushes down the tip of the small-diameter produce-stabilizing member 4d of the receiving seat 4 downwardly to widen the opening 4f. It is placed so as to fit into the central opening of 4c. At that time, the cylindrical body 4b hardly shrinks downward with the weight of the agricultural product having a small diameter. The small-diameter agricultural product A3 is placed on the receiving member 4c with the upper part of the small-diameter agricultural product A3 exposed upward from the upper part of the cylindrical body material 4b, and is flexibly elastically deformed at the time of placement. Horizontal support is performed by the small-diameter agricultural product support piece 4h provided in the upper part.
[0061]
A tray 1 on which a small-diameter agricultural product is placed is directed toward the measurement unit on the conveyor of the agricultural product sorting device, and illumination light is irradiated from the side by a light source (not shown) in the measurement unit, and the transmitted light is a hole for measurement. The light is guided to a light receiving unit (not shown) through 4a and 2a. At that time, since the inner peripheral part 4e of the receiving member 4c is flexibly elastically deformed downward and closely contacts the outer peripheral surface of the small-diameter agricultural product A3 along the circumferential direction, disturbance light is generated on the outer surface of the small-diameter agricultural product A3 and the receiving member 4c. It does not enter through the gap.
[0062]
Even if the small-diameter agricultural product A3 is swayed in any direction with respect to the horizontal direction during transportation, the small-diameter agricultural product A3 is supported at a high position by the small-diameter agricultural product support piece 4h. It can be supported and transported without changing the posture of the small-diameter agricultural product or falling down.
[0063]
The medium-diameter agricultural product A2 having a medium-diameter size agricultural product placed on the saucer 1 and not heavy enough to shrink the receiving seat 4 is a support piece for the produce-stabilizing member 3 provided on the upper part of the saucer body 2. 3c and the support 4h for small-diameter agricultural products formed on the cylindrical body 4b of the receiving seat 4 are pushed down downward in a curved state in accordance with the outer peripheral surface of the medium-diameter agricultural product A2, and the agricultural product anti-sway member 3 is placed on the receiving member 4c in a state where the horizontal support is elastically performed by the support pieces 3c.
[0064]
In addition, as shown in FIG. 4, when the agricultural product placed on the saucer 1 has a large diameter, the large-diameter agricultural product A <b> 1 has the support piece 3 c of the agricultural product anti-sway member 3 provided on the upper part of the saucer body 2 at its root. It is pushed down in a curved state according to the outer peripheral surface of the large-diameter agricultural product A1 that comes into contact with the side, and further, the cylindrical body 4b of the receiving seat 4 is folded downward by its own weight and directed downward. The large-diameter agricultural product A1 is placed on the receiving member 4c that is shrunk and lowered to a low position, and the placement stability of the large-diameter agricultural product A1 is achieved. At that time, the small-diameter agricultural product support piece 4h formed on the cylindrical body 4b of the receiving seat 4 is pushed downward in a curved state in accordance with the outer peripheral surface of the large-diameter agricultural product A1 that comes into contact with it, thereby blocking ambient light.
[0065]
As described above, according to the present embodiment, if the agricultural product placed on the saucer 1 has a small diameter, the anti-swaying member 4d for the small-diameter agricultural product of the receiving seat 4 can surely perform the anti-swaying, so that the agricultural product has a medium diameter or larger. For example, the rocks are reliably prevented by the support pieces 3c of the agricultural product rocking member 3 provided on the upper part of the tray body 2. Such an anti-swaying effect can be obtained by simply placing the produce on the tray 1 regardless of the size of the produce.
[0066]
The cylindrical seat 4c can be expanded and contracted in the vertical direction in the receiving seat 4, and it contracts in the vertical direction with respect to a heavy agricultural product (generally a large-diameter agricultural product) A1, and the receiving member 4c is By lowering, the gravity center position of the large-diameter agricultural product A1 is also lowered, and the shaking of the heavy and large agricultural product A1 can be surely stopped.
[0067]
In addition, the small-diameter agricultural product anti-sway member 4d for anti-swaying the small-diameter agricultural product A3 and the anti-swaying member 3 for anti-swaying the medium-sized or larger agricultural product are configured to abut over the entire circumference of the agricultural product. There is no need to restrict the direction of the conveyance direction as in the past, and it is necessary to provide a structure for regulating the direction of the conveyance direction on the tray, and to provide a structure for making the tray a predetermined direction on the agricultural product sorting apparatus side There is no.
(Second Embodiment)
FIG. 5 shows a second embodiment of the present invention. In this embodiment, the same elements as those shown in the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and the description thereof is omitted.
[0068]
In the first embodiment described above, the receiving member 4c on which the agricultural product is placed is integrally provided on the cylindrical body 4b having the bellows structure. However, in this embodiment, the small-diameter agricultural product shakes. A cylindrical body 14 having a bellows structure provided with a stopper member 4d and a cylindrical receiving seat 15 on which agricultural products are placed are formed as separate structures, and the inner periphery of the mounting seat 2'c of the tray body 2 The lower part of the seat 15 is mounted on the side, and the lower part of the cylindrical body 14 is mounted on the outer periphery of the mounting seat 2'c. As shown in FIG. 15 is arranged.
[0069]
The cylindrical body 14 and the receiving seat 15 are both formed of an elastic member such as rubber, and the flat upper surface of the receiving seat 15 is used as a product mounting surface. The upper surface of the receiving seat 15 is the upper surface of the cylindrical body 14. It is located below the small-diameter agricultural product swaying member 4d. The size of the bellows of the cylindrical body 14 is the same as that of the cylindrical body 4b in the first embodiment shown in FIG. 1, and the four support pieces are formed by dividing the small-diameter agricultural product anti-sway member 4d into four parts. The height of 14h is provided at the same height as the support piece 4h provided on the cylindrical body 4b shown in FIG.
[0070]
In addition, the receiving member 15 c forming the agricultural product placement surface, which is the upper surface of the receiving seat 15, is set to a height that matches the third indirect position from the bottom of the cylindrical body 14. Therefore, the height of the receiving member 15c and the support piece 14h which form the mounting surface of the receiving seat 15 is the same as the height of the receiving member 4c and the support piece 4h shown in FIG.
[0071]
In the tray 11 having such a configuration, when the agricultural product placed on the tray 11 is a small-diameter agricultural product, the inner peripheral portion 15e of the receiving member 15c of the receiving seat 15 is directed downward along the outer peripheral surface of the agricultural product. It is flexibly elastically deformed to block ambient light. In addition, the small-diameter agricultural product placed on the seat 15 is supported at a substantially middle position as shown in FIG. 3 by the small-diameter agricultural product rocking member 4d positioned above, and prevents the small-diameter agricultural product from shaking. Can fully fulfill. At that time, since the receiving seat 15 does not shrink downward, the upper portion of the small-diameter agricultural product can be exposed above the receiving tray 11 to reliably irradiate illumination light for measurement.
[0072]
On the other hand, as for the receiving seat 15, even if a heavy agricultural product is placed, the receiving member 15c does not fall downward as in the first embodiment. However, since the lower part of the agricultural product is fitted into the central opening of the receiving member 15c of the receiving seat 15 and the inner peripheral portion 15e of the receiving member 15c is flexibly elastically deformed as described above, the agricultural product sinks downward accordingly. The center of gravity is lowered, and heavy and large-diameter agricultural products can be placed stably.
[0073]
As described above, in the present embodiment, since the seat 15 and the cylindrical body 14 are separate structures, the cylindrical body 14 does not need a function as a seat as in the first embodiment. Yes, it is only necessary to perform the function of preventing the small-diameter agricultural product from shaking, and the configuration of the cylindrical body 14 can be simplified.
[0074]
And, since the agricultural products having a medium diameter or larger are prevented from shaking by the separately provided agricultural product rocking member 3c, the small-diameter agricultural product rocking member 4d provided on the upper portion of the cylindrical body 14 has an intermediate diameter or larger agricultural product. However, the cylindrical body 14 is formed in an accordion shape and is shrunk downward by an agricultural product having a weight of about a medium diameter or more, so it is an obstacle to the placement on the seat 15. It will never be. Rather, since the four support pieces 14h constituting the small-diameter agricultural product swaying prevention member 4d are brought into contact with the outer peripheral surface of the agricultural product, an effect of shielding disturbance light can be obtained.
(Third embodiment)
FIG. 6 shows a third embodiment of the present invention. In this embodiment, the same elements as those shown in the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and the description thereof is omitted.
[0075]
This embodiment shows a modification of the first embodiment shown in FIGS.
[0076]
In the present embodiment, the structure in which the receiving member 4c on which the agricultural product is placed is integrally provided on the cylindrical body 24b having the bellows structure is used as the receiving seat 24, is the receiving structure in the first embodiment shown in FIG. Although it is the same structure as the seat 4, it differs in the point which provided one more indirect number in the bellows structure of the cylindrical body 24b than the cylindrical body 4b in 1st Embodiment.
[0077]
In the present embodiment, the cylindrical body 24b is provided with a receiving member 4c that is the fourth indirectly from the bottom, and when a heavy agricultural product is placed on the receiving member 4c that forms the placing surface of the agricultural product, the receiving member 4c Since the stroke that can sink is longer than that of the cylindrical body 4b of the first embodiment, the cylindrical body 24b sinks positively when a heavy agricultural product is placed, and is placed more stably. Is done.
[0078]
Moreover, although the height of the outer peripheral wall part 2b of the saucer main body 2 is made high according to the part to which the cylindrical body 24b became long, 4d of the small-diameter agricultural product rocking prevention member 4d provided in the upper part of the cylindrical body 24b Since the distance between the receiving member 4c and the cylindrical body 4b of the first embodiment is the same as that of the cylindrical body 4b of the first embodiment, the effect of preventing the small-diameter agricultural product from shaking by the four support pieces 4h constituting the small-diameter agricultural product shaking-preventing member 4d is the first. It is obtained in the same manner as in the embodiment.
[0079]
【The invention's effect】
According to the first aspect of the invention, if the agricultural product to be placed on the saucer has a small diameter, the second agricultural product anti-sway member is flexibly elastically deformed and placed on the receiving member. The small-diameter agricultural products are prevented from shaking by the two agricultural products shaking-preventing members. Since this second agricultural product anti-sway member supports the circumferential direction of the agricultural product from the side substantially over the entire circumference, in the agricultural product sorting device, the attitude of the agricultural product changes or falls on the saucer due to vibration etc. Can be transported without any problem.
[0080]
In addition, even if the small-diameter agricultural product is placed on the receiving member, the receiving member itself does not sink downward, and the distance between the receiving member and the upper surface of the receiving tray is such that the upper part of the small-diameter agricultural product is exposed, When the measuring device provided in the agricultural product sorting device is a transmitted light measuring device, it is possible to sufficiently irradiate the agricultural product with illumination light from the light source with the agricultural product placed on the receiving member.
[0081]
Furthermore, when the produce to be placed on the saucer has a medium diameter or more, the produce is placed on the receiving member by moving the cylindrical body downward while flexibly elastically deforming the second produce-stabilizing member. The agricultural product swinging member will not get in the way. In that case, it supports from the side over the circumferential direction substantially the perimeter of agricultural products by the 1st agricultural product rocking | fluctuation prevention member.
[0082]
Moreover, since both the 1st agricultural product anti-sway member and the 2nd agricultural product anti-sway member support the circumferential direction of agricultural products from the side over substantially the entire circumference, the mounting direction of the tray is limited with respect to the agricultural product sorting device. There is nothing.
[0083]
In this way, regardless of the size of the agricultural product (weight according to the size), the agricultural product to be placed can be stably supported and transported only by placing the agricultural product on the tray.

According to the invention which concerns on Claim 3, the role of a receiving member and the role of a cylindrical body can be made separate, the simplification of the structure of a receiving member and a cylindrical body can be achieved, and a receiving member and a cylindrical shape Increased freedom of body design.
[0087]
According to the invention which concerns on Claim 4, when the transmitted light measuring device is used as the measuring device of the agricultural product sorting device, when the agricultural product placed on the tray is irradiated with illumination light from the upper side, the transmitted light provided on the receiving member The transmitted light is emitted from the measurement through-hole, and the transmitted light is received by the light receiving means, whereby the sugar content, the maturity, etc. of the agricultural product can be measured.
[0088]
According to the invention according to claim 5, when the transmitted light measuring device is used as the measuring device of the agricultural product sorting device, disturbance light does not enter the transmitted light emitted from the agricultural product, so the sugar content of the agricultural product with high accuracy, Maturity etc. can be measured.
[0089]
According to the invention of claim 6, since the cylindrical body has a bellows structure, the spring constant can be easily managed when the cylindrical body is elastically expanded and contracted in the vertical direction, and the cylindrical body can be expanded and contracted. Sufficient light shielding property can be obtained while allowing.
[0090]
According to the seventh aspect of the present invention, when a heavy agricultural product is placed on the second agricultural product anti-sway member, the second agricultural product anti-sway member is flexibly elastically deformed until the agricultural product is placed on the receiving member. When the heavy product of medium diameter or larger is placed on the receiving tray, the second produce anti-sway member and the cylindrical member become an obstacle to placing the agricultural product on the receiving member. There is no.
[0091]
