本発明は、計測対象の農作物を受止め支持する水平姿勢と前記農作物を放出対象箇所に向けて放出する傾斜姿勢とにわたり水平軸芯周りで揺動自在に載置部が支持され、前記載置部に受止め支持されている状態で前記農作物の重量が重量計測装置により計測されるように構成された農作物計測用の受止め支持装置に関する。   In the present invention, the mounting portion is supported so as to be swingable around a horizontal axis between a horizontal posture for receiving and supporting the crop to be measured and an inclined posture for discharging the crop toward the discharge target location. The present invention relates to a receiving and supporting device for measuring crops configured such that the weight of the crop is measured by a weight measuring device while being received and supported by a portion.

上記農作物計測用の受止め支持装置の従来構成として、次のように構成されたものがあった。つまり、搬送コンベアにおける農作物載置用のものとして構成されており、前記載置部に相当するバケットが傾動部材を介して水平軸芯周りで揺動自在に支持され、傾動部材が、係止具にて係止保持されることにより水平姿勢に維持され、係止具による係止保持を解除すると自重で傾斜姿勢に切り換わり、バケットに載置している農作物を外部に放出させるように構成され、又、傾動部材に対して上下方向に沿って所定範囲内で移動自在にバケットが支持され、このバケットに受止め支持されている状態で農作物の重量を重量計測装置により計測することができるように構成されたものがあった。   As a conventional configuration of the above-described receiving and supporting device for measuring crops, there is one configured as follows. That is, it is configured for placing crops on a conveyor, and a bucket corresponding to the above-described placement unit is supported to be swingable around a horizontal axis via a tilting member, and the tilting member is a locking tool. Is held in a horizontal position by being held in place, and when it is released from the holding state by the locking tool, it is switched to an inclined position by its own weight, and the crops placed in the bucket are discharged to the outside.

There was something configured.

特開２００１−２７８４３１号公報JP 2001-278431 A

上記従来構成では、係止具による係止保持を解除すると自重で載置部が傾斜姿勢に切り換わり、受止め支持している農作物を外部に放出させるように構成されるものであり、例えば、計測作業を長期にわたり実行すると、経年変化により傾動部材の揺動枢支部の摩擦抵抗が大きくなり揺動操作が円滑に行えないものとなり、傾動部材を傾斜姿勢へ切り換えて農作物を外部に放出させる作業が良好に行えなくなるおそれがあった。   In the above conventional configuration, when the holding by the locking tool is released, the placing portion switches to an inclined posture by its own weight, and is configured to discharge the crop that is received and supported to the outside. If measurement work is performed over a long period of time, the frictional resistance of the pivoting support part of the tilting member will increase due to secular change, and the swinging operation will not be able to be performed smoothly. There was a possibility that it could not be performed well.

又、上記従来構成では、搬送コンベアにおける農作物載置用のものとして構成されており、搬送コンベアが移送するに伴って、重量計測装置による重量計測箇所を通過する際に、傾動部材に対してバケットを相対的に上方に移動するように案内しながら重量を計測することは可能であるが、例えば、このような受止め支持装置を、重量計測箇所に対して位置固定状態で設け、計測が終了したのち、計測が終了した農作物を例えば搬送コンベア上に放出させるような構成のものに適用すると、この構成では、重量計測装置による重量計測箇所と搬送コンベアにおける農作物載置箇所との間には所定の間隔を設ける必要があり、上述したような載置部が自重で傾斜姿勢に切り換わるものでは、農作物を搬送コンベア上に放出させることを良好に行えないおそれがある。   Moreover, in the said conventional structure, it is comprised as a thing for crop mounting in a conveyance conveyor, and when a conveyance conveyor transfers, when passing the weight measurement location by a weight measurement apparatus, it is a bucket with respect to a tilting member. Although it is possible to measure the weight while guiding it to move relatively upward, for example, such a receiving support device is provided in a fixed position with respect to the weight measurement location, and the measurement is completed. After that, when applied to a configuration in which the measured crop is discharged onto, for example, a transport conveyor, in this configuration, there is a predetermined distance between the weight measurement location by the weight measurement device and the crop placement location on the transport conveyor. In the case where the mounting unit as described above switches to an inclined posture due to its own weight, it is preferable to discharge the crop onto the conveyor. There is no fear.

本発明の目的は、載置部に受止め支持されている状態で農作物の重量を良好に計測することができるものでありながら、農作物の放出対象箇所への放出を良好に行えるようにすることが可能な農作物計測用の受止め支持装置を提供する点にある。   An object of the present invention is to allow the weight of a crop to be favorably measured in a state where it is received and supported by the mounting portion, and to allow the crop to be discharged to a target location. It is in the point which provides the receiving support apparatus for the crop measurement which can do.

本発明に係る農作物計測用の受止め支持装置は、計測対象の農作物を受止め支持する水平姿勢と前記農作物を放出対象箇所に向けて放出する傾斜姿勢とにわたり水平軸芯周りで揺動自在に載置部が支持され、前記載置部に受止め支持されている状態で前記農作物の重量が重量計測装置により計測されるように構成されたものであって、その第１特徴構成は、前記受止め支持装置が、前記重量計測装置に対して位置固定状態で備えられ、前記載置部が、計測対象の農作物を受止め支持可能で且つ前記水平姿勢にて前記重量計測装置の計測作用部に接当作用する作物受け部材と、その作物受け部材を保持しながら前記水平姿勢と前記傾斜姿勢とにわたり前記水平軸芯周りで揺動自在に設けられた揺動保持部材と、前記作物受け部材を前記水平姿勢にて前記揺動保持部材に対して所定範囲内で上下方向に相対移動自在に保持する融通部とを備えて構成され、前記揺動保持部材を前記水平姿勢と前記傾斜姿勢とにわたって揺動操作すべく駆動操作自在な姿勢変更操作手段が備えられている点にある。 The receiving support apparatus for measuring crops according to the present invention is swingable around a horizontal axis between a horizontal posture for receiving and supporting the crop to be measured and an inclined posture for discharging the crop toward the discharge target location. The placing portion is supported, and the weight of the crop is measured by the weight measuring device in a state where the placing portion is received and supported by the placing portion. receiving the support device, provided with respect to the weight measuring device in position fixed state, the mounting section is measured effect of the weight measuring apparatus by the support possible and the horizontal position receiving the crop to be measured A crop receiving member that comes into contact with a portion, a swing holding member that is swingable around the horizontal axis around the horizontal posture and the inclined posture while holding the crop receiving member, and the crop receiver The horizontal position of the member The swing holding member is configured to be swingable between the horizontal posture and the inclined posture. Accordingly, there is provided a posture changing operation means that can be driven and operated as much as possible.

第１特徴構成によれば、計測対象の農作物が作物受け部材によって受止め支持され、この作物受け部材を保持する揺動保持部材が水平姿勢と傾斜姿勢とにわたり水平軸芯周りで揺動自在に設けられ、且つ、作物受け部材を水平姿勢にて揺動保持部材に対して所定範囲内で上下方向に相対移動自在に保持する融通部が設けられるから、揺動保持部材が水平姿勢にあるときに作物受け部材に計測対象の農作物を受止め支持している状態で、作物受け部材が重量計測装置の計測作用部に接当作用して農作物の重量を計測することができ、姿勢変更操作手段によって駆動操作することによって、揺動保持部材を傾斜姿勢に切り換えて計測処理が終了した農作物を放出対象箇所に向けて放出させることができる。   According to the first characteristic configuration, the crop to be measured is received and supported by the crop receiving member, and the swing holding member that holds the crop receiving member can swing around the horizontal axis between the horizontal posture and the inclined posture. When the swinging holding member is in the horizontal position, the interchangeable part is provided to hold the crop receiving member in the horizontal position so as to be relatively movable in the vertical direction within a predetermined range with respect to the swinging holding member. With the crop receiving member receiving and supporting the crop to be measured, the crop receiving member can contact the measuring action portion of the weight measuring device to measure the weight of the crop, and the posture changing operation means As a result of the drive operation, the swing holding member can be switched to the tilted posture, and the crops for which the measurement process has been completed can be discharged toward the discharge target location.

そして、作物受け部材が揺動保持部材に対して所定範囲内で上下方向に相対移動自在であるから、揺動保持部材が水平姿勢であり且つ作物受け部材に農作物を受止められている状態で、作物受け部材を重量計測装置の計測作用部に接当作用して農作物の重量を計測するときに、作物受け部材が揺動保持部材に対して相対的に上方に移動させた状態にすることで、作物受け部材と揺動保持部材との上下方向での縁を切ることができ、揺動保持部材による影響を受け難い状態で適正に農作物の重量を計測することが可能となる。   Since the crop receiving member is movable relative to the swing holding member in the vertical direction within a predetermined range, the swing holding member is in a horizontal posture and the crop receiving member receives the crop. When the crop receiving member is brought into contact with the measuring action part of the weight measuring device to measure the weight of the crop, the crop receiving member is moved upward relative to the swing holding member. Thus, the vertical edges of the crop receiving member and the swing holding member can be cut, and the weight of the crop can be appropriately measured without being affected by the swing holding member.

上述したように、作物受け部材は重量計測装置に対して接当作用する構成であり、作物受け部材は重量計測装置から分離した状態で備えることが可能であり、又、揺動保持部材は重量計測装置と分離した状態で設けられるので、本装置を、既存の重量計測装置に対して特別な構造改良を加えることなく後付けで装着させることが可能である。   As described above, the crop receiving member is configured to abut against the weight measuring device, the crop receiving member can be provided in a state separated from the weight measuring device, and the swing holding member is weighted. Since it is provided in a state separated from the measuring device, the present device can be attached later without adding a special structure to the existing weight measuring device.

そして、揺動保持部材が姿勢変更操作手段によって駆動操作されるので、長期の使用による経年変化により揺動保持部材が揺動し難い状態になることがあっても、姿勢変更操作手段の駆動力によって良好に姿勢変更させることができる。しかも、姿勢変更操作手段の駆動力によって姿勢変更させるものであるから、自重で揺動させるもののように揺動支点位置について特に制約を受けることがなく、例えば、揺動支点位置を横一側箇所に位置させて、揺動保持部材を傾斜姿勢に切り換える際に、大きく外方側に張り出すように姿勢変更させることも可能であり、受止め支持装置と放出対象箇所との間が離間していても、計測処理が終了した農作物を放出対象箇所に向けて良好に放出させることが可能となる。   Since the swing holding member is driven by the posture changing operation means, the driving force of the posture changing operation means even if the swing holding member is difficult to swing due to secular change due to long-term use. Can change the posture well. In addition, since the posture is changed by the driving force of the posture changing operation means, the swing fulcrum position is not particularly restricted as in the case of swinging by its own weight. When the swing holding member is switched to the tilted position, the posture can be changed so as to protrude largely outward, and the receiving support device and the discharge target portion are separated from each other. However, it is possible to favorably release the crops for which the measurement process has been completed toward the release target location.

従って、載置部に受止め支持されている状態で農作物の重量を良好に計測することができるものでありながら、農作物の放出対象箇所への放出を良好に行えるようにすることが可能な農作物計測用の受止め支持装置を提供できるに至った。
本発明の第２特徴構成は、円状の挿通孔を前記揺動保持部材に備え、前記挿通孔よりも小径で円状の小径部分を前記作物受け部材に備えて、前記作物受け部材の小径部分を前記揺動保持部材の挿通孔に位置させることにより、前記融通部を構成している。 Therefore, a crop that can measure the weight of the crop in a state where it is received by and supported by the mounting portion, and can release the crop to the target location. It has become possible to provide a receiving support device for measurement.
The second characteristic configuration of the present invention includes a circular insertion hole in the swing holding member, a small diameter portion having a smaller diameter than the insertion hole and a circular shape in the crop receiving member, and a small diameter of the crop receiving member. The interchangeable portion is configured by positioning the portion in the insertion hole of the swing holding member.

本発明の第３特徴構成は、前記水平姿勢の前記揺動保持部材の下端が受止め規制されるように前記姿勢変更操作手段による操作範囲が設定されている点にある。 A third characteristic configuration of the present invention is that an operation range by the posture changing operation means is set so that a lower end of the swing holding member in the horizontal posture is received and restricted.

第３特徴構成によれば、揺動保持部材は、姿勢変更操作手段によって駆動操作されることにより、水平姿勢と傾斜姿勢とにわたって水平軸芯周りで揺動するが、水平姿勢にあるときは揺動保持部材の下端が受止め規制されることになる。 According to the third characteristic configuration , the swing holding member swings around the horizontal axis between the horizontal posture and the inclined posture by being driven by the posture changing operation means. The lower end of the moving holding member is received and restricted.

そして、作物受け部材は水平姿勢にて揺動保持部材に対して所定範囲内で上下方向に相対移動自在に保持されるので、揺動保持部材の下端が受止め規制されている状態で、作物受け部材が重量計測装置の計測作用部に接当作用するとき、その接当作用によって下端が受止め規制されている揺動保持部材に対して、作物受け部材が上方に持ち上がった状態となるように位置を設定しておくと、揺動保持部材による影響を受けない状態で農作物の重量を精度よく計測することができる。   The crop receiving member is held in a horizontal posture so as to be relatively movable in the vertical direction within a predetermined range with respect to the swing holding member, so that the crop receiving member is received and regulated at the lower end of the swing holding member. When the receiving member comes into contact with the measuring action portion of the weight measuring device, the crop receiving member is lifted upward with respect to the swinging holding member whose lower end is received and restricted by the contact action. If the position is set in advance, the weight of the crop can be accurately measured without being affected by the swing holding member.

本発明の第４特徴構成は、前記作物受け部材における農作物排出箇所に、前記農作物を前記放出対象箇所に向けて載置案内する案内体が延長形成されている点にある。 The 4th characteristic structure of this invention exists in the point which the guide body which mounts and guides the said crop toward the said discharge | release target location is extendedly formed in the crop discharge location in the said crop receiving member.

第４特徴構成によれば、揺動保持部材を傾斜姿勢に切り換えて、農作物を放出対象箇所に向けて放出させるときには、作物受け部材における農作物排出箇所に延長形成されている案内体により農作物が放出対象箇所に向けて載置案内されるので、農作物を傷つけるおそれの少ない状態で農作物の放出対象箇所への放出を良好に行うことができる。 According to the fourth characteristic configuration , when the swing holding member is switched to the inclined posture and the crop is discharged toward the discharge target location, the crop is released by the guide body that is extended to the crop discharge location in the crop receiving member. Since it is placed and guided toward the target location, it is possible to favorably release the crop to the target location with little risk of damaging the crop.

つまり、上部側部材２４Ａと大径部分２４Ｂ２との間の上下間隔分だけ底板部分３１に対して上下方向に相対移動自在で、且つ、抜け外れが阻止される状態で、底板部分３１に保持される構成となっており、このような作物受け部材２４の底板部分３１に対する支持構造により、上部側及び下部側部材２４Ａ，２４Ｂと底板部分３１との間に融通部２６が構成されている。   That is, it is held by the bottom plate portion 31 in such a manner that it can move in the vertical direction relative to the bottom plate portion 31 by the vertical distance between the upper side member 24A and the large diameter portion 24B2 and is prevented from coming off. With such a support structure for the bottom plate portion 31 of the crop receiving member 24, the interchangeable portion 26 is configured between the upper and lower side members 24 </ b> A and 24 </ b> B and the bottom plate portion 31.

又、揺動保持部材２５の内面側及び作物受け部材２４の上部載置面には、夫々、農作物Ｎが損傷しないように例えばスポンジ等からなる軟質のクッション材４０を備えている。   Further, on the inner surface side of the swing holding member 25 and the upper placement surface of the crop receiving member 24, a soft cushion material 40 made of, for example, a sponge is provided so that the crop N is not damaged.

図４及び図５に示すように、幅広の傾斜板部分２９ａの外周面側における上部側箇所から外方に延設した一対の支持アーム３３が、計測装置１７の収納ケース１８に設けられた一対の固定ブラケット３４に対して水平軸Ｐ３周りで揺動自在に枢支連結される構成となっている。又、操作アーム２８は、帯板をＬ形に折り曲げたアングル材からなり、幅広の傾斜板部分２９ａの外周面側における下部側箇所に固着されて、その幅広の傾斜板部分２９ａの板面方向に沿って外方に延びる状態で設けられている。この操作アーム２８の延出側端部２８ａには、揺動保持部材２５を水平姿勢と傾斜姿勢とにわたって揺動操作すべく駆動操作自在な姿勢変更操作手段としてのエアーシリンダ３５が枢支連結されている。   As shown in FIGS. 4 and 5, a pair of support arms 33 extending outward from the upper side portion on the outer peripheral surface side of the wide inclined plate portion 29 a are provided in the storage case 18 of the measuring device 17. The fixed bracket 34 is pivotally connected so as to be swingable around the horizontal axis P3. Further, the operation arm 28 is made of an angle material obtained by bending the belt plate into an L shape, and is fixed to a lower side portion on the outer peripheral surface side of the wide inclined plate portion 29a, and the plate surface direction of the wide inclined plate portion 29a Is provided in a state extending outward along the line. An air cylinder 35 is pivotally connected to the extended end portion 28a of the operation arm 28 as a posture changing operation means that can be driven to swing the swing holding member 25 in a horizontal posture and an inclined posture. ing.

エアーシリンダ３５は２台の計測装置１７の夫々に各別に備えられるが、図１に示すように、各計測装置１７の操作アーム２８が互いに近づくように延設されており、２つのエアーシリンダ３５を近接させた状態で配備する構成となっている。このようにして、駆動用のエアー配管を短くしてエアーシリンダ３５の駆動構成を簡素化することが可能な配置構成としている。又、エアーシリンダ３５が伸縮作動する箇所は、上方側を側面視円弧状のカバー体３６にて覆ってある。   The air cylinders 35 are provided separately for each of the two measuring devices 17. However, as shown in FIG. 1, the operation arms 28 of the measuring devices 17 are extended so as to approach each other, and the two air cylinders 35 are provided. It is the composition which is deployed in the state where it is brought close to. In this manner, the driving air piping is shortened to simplify the driving configuration of the air cylinder 35. Further, the portion where the air cylinder 35 is expanded and contracted is covered with a cover body 36 having an arc shape in a side view.

エアーシリンダ３５を伸縮操作することにより、揺動保持部材２５を水平姿勢（図５参照）と傾斜姿勢（図７参照）とにわたって水平軸芯Ｐ３周りで揺動操作することができるのであり、揺動保持部材２５を水平姿勢にしている状態で、計測対象の農作物Ｎを受止め支持して、農作物Ｎの重量及び糖酸度を計測することができる。 By extending and contracting operation of the air cylinder 35, and as it can you to swung in the horizontal axis P3 around over the swing support member 25 and a horizontal position (see FIG. 5) and inclined position (see FIG. 7), In a state where the swing holding member 25 is in the horizontal posture, the crop N to be measured is received and supported, and the weight and sugar acidity of the crop N can be measured.

そして、水平姿勢の揺動保持部材２５の下端が受止め規制されるように、エアーシリンダ３５による操作範囲が設定されている。
説明を加えると、図５〜図７に示すように、収納ケース１８の天板３７に、計測用ヘッド部２３が上方に向けて露出するように上下に挿通する円形の挿通孔３８が形成され、天板３７の上面における挿通孔３８の外周部に周方向に沿って円環状のゴム板３９が設けられ、水平姿勢に切り換えられた揺動保持部材２５をこのゴム板３９により受止めてそれ以上の移動を規制するように構成されている。尚、このとき、揺動保持部材２５における平面視矩形状の支持枠部２７における四隅の角部だけがゴム板３９に接当作用して水平姿勢の揺動保持部材２５の下端が受止め規制されることになる。 An operation range by the air cylinder 35 is set so that the lower end of the swing holding member 25 in the horizontal posture is received and restricted.
In other words, as shown in FIGS. 5 to 7, a circular insertion hole 38 is formed in the top plate 37 of the storage case 18 so that the measurement head portion 23 is vertically exposed so as to be exposed upward. An annular rubber plate 39 is provided along the circumferential direction on the outer peripheral portion of the insertion hole 38 on the upper surface of the top plate 37, and the swing holding member 25 switched to the horizontal posture is received by the rubber plate 39. It is comprised so that the above movement may be controlled. At this time, only the corners of the four corners of the support frame portion 27 having a rectangular shape in plan view in the swing holding member 25 are brought into contact with the rubber plate 39, and the lower end of the swing support member 25 in the horizontal posture is prevented from receiving. Will be.

水平姿勢の揺動保持部材２５の下端が受止め規制されても、作物受け部材２４は融通部２６にて許容されている所定範囲内で上下方向に相対移動することが可能であり、挿通孔３８を挿通する状態で計測用ヘッド部２３に直接に接当作用することができ、揺動保持部材２５による影響を受けない状態で農作物Ｎの重量を精度よく計測することができる。   Even if the lower end of the swing holding member 25 in the horizontal posture is restricted from being received, the crop receiving member 24 can be relatively moved in the vertical direction within a predetermined range allowed by the accommodation portion 26, and the insertion hole 38 can be directly contacted with the measurement head portion 23 in a state of being inserted, and the weight of the crop N can be accurately measured without being affected by the swing holding member 25.

すなわち、図５に示すように、水平姿勢の揺動保持部材２５の下端が受止め規制され、さらに、作物受け部材２４の上部側部材２４Ａが計測用ヘッド部２３の上端に接当作用している状態で、上部側部材２４Ａと底板部分３１との間に所定の間隔で隙間が形成され、且つ、下部側部材２４Ｂの大径部分２４Ｂ２と底板部分３１との間にも所定の間隔で隙間が形成されるように、エアーシリンダ３５による操作範囲の下限位置、すなわち、揺動保持部材２５の下限操作位置が設定されている。   That is, as shown in FIG. 5, the lower end of the swing holding member 25 in the horizontal posture is received and restricted, and the upper side member 24 </ b> A of the crop receiving member 24 is brought into contact with the upper end of the measurement head portion 23. In this state, a gap is formed at a predetermined interval between the upper side member 24A and the bottom plate portion 31, and a gap is also formed at a predetermined interval between the large diameter portion 24B2 and the bottom plate portion 31 of the lower side member 24B. The lower limit position of the operation range by the air cylinder 35, that is, the lower limit operation position of the swing holding member 25 is set.

図７に示すように、エアーシリンダ３５を伸長操作させて揺動保持部材２５を傾斜姿勢に切り換えると、作物受け部材２４に載置支持されている農作物Ｎを搬送コンベア２の放出対象位置に位置する載置部材１０に向けて放出させることができる。   As shown in FIG. 7, when the air cylinder 35 is extended and the swing holding member 25 is switched to the inclined posture, the crop N placed and supported on the crop receiving member 24 is positioned at the discharge target position of the transport conveyor 2. It can discharge | release toward the mounting member 10 to do.

このように農作物Ｎを搬送コンベア２に向けて放出させるとき、上述したように、支持枠部２７における農作物Ｎの排出箇所に幅広の傾斜板部分２９ａが延長形成されていることから、揺動保持部材２５と載置部材１０との間の隙間を狭くすることができ、それらの隙間に農作物Ｎが挟まれて損傷する等の不利を回避できる。   In this way, when the crop N is discharged toward the transport conveyor 2, as described above, the wide inclined plate portion 29a is formed to extend at the discharge portion of the crop N in the support frame portion 27. The gap between the member 25 and the mounting member 10 can be narrowed, and disadvantages such as damage caused by the crop N being sandwiched between the gaps can be avoided.

計測部１は、農作物Ｎの重量や糖酸度を計測するものであるが、農作物Ｎの重量の計測は、計測用ヘッド部２３に上方側から荷重がかかると、その荷重の大きさをロードセル１９によって計測することができるように構成され、又、図示はしないが、計測用ヘッド部２３には、載置される農作物Ｎに向けて赤外光を照射するための照射部や内部を透過した光や反射した光を受光する受光部等が設けられ、受光部の受光情報に基づいて糖酸度測定器２０が周知の計測手法である分光分析手法によって糖度や酸度を計測する構成となっている。   The measuring unit 1 measures the weight and sugar acidity of the crop N. When measuring the weight of the crop N when a load is applied to the measuring head unit 23 from above, the load cell 19 determines the magnitude of the load. Although not shown, the measurement head unit 23 is transmitted through an irradiation unit for irradiating infrared light toward the mounted crop N and the inside thereof, although not illustrated. A light receiving unit or the like that receives light or reflected light is provided, and the sugar acidity measuring device 20 is configured to measure sugar content and acidity by a spectral analysis method that is a well-known measurement method based on light reception information of the light receiving unit. .

作物受け部材２４の上部側部材２４Ａには、計測対象となる農作物Ｎに対して赤外光を照射したり、透過光や反射光を受光するために、光通過用の通過孔４１が形成されており、又、小径の農作物Ｎであっても適正に重量計測や糖酸度計測が行えるように支持する保持部４２が設けられている。   The upper side member 24A of the crop receiving member 24 is formed with a passage hole 41 for passing light in order to irradiate the crop N to be measured with infrared light and to receive transmitted light and reflected light. In addition, a holding unit 42 is provided to support the weight N and the sugar acidity appropriately even if the crop N has a small diameter.

この農作物選別用設備には、計測部１の計測情報や搬送コンベア２の移動距離情報等に基づいて、搬送する農作物Ｎのランクを搬送位置と関連付けて管理して、計測が終了した農作物Ｎを搬送コンベア２により搬送しながら該当するランクの回収容器３に回収して収集するように、エアーシリンダ３５、各ソレノイド１６等の作動を制御する制御部（図示せず）が備えられている。   In this crop sorting facility, the rank of the crop N to be transported is managed in association with the transport position based on the measurement information of the measuring unit 1 and the movement distance information of the transport conveyor 2, and the crop N for which measurement has been completed is managed. A control unit (not shown) for controlling the operation of the air cylinder 35, each solenoid 16 and the like is provided so as to be collected and collected in the collection container 3 of the corresponding rank while being transported by the transport conveyor 2.

この農作物選別用設備における農作物Ｎの選別処理について説明する。
先ず、外部からコンテナ等により貯留された多量の農作物Ｎが載置台４３に載置される。そして、作業者が手作業により１個ずつ農作物Ｎを計測装置１７における作物受け部材２４上に載置させると、制御部は、ロードセル１９の検出結果から農作物Ｎが載置されたことが判るので、すぐに、その計測対象となる農作物Ｎについて重量と糖酸度を計測する。そして、その計測結果からいずれのランクに相当するかが判定される。図示はしないが、このとき、計測装置１７の操作パネル部１７Ａに計測結果（ランク）や計測が終了したことが表示される。 The sorting process of the crop N in this crop sorting equipment will be described.
First, a large amount of the crop N stored by a container or the like from the outside is placed on the placing table 43. When the worker manually places the crops N one by one on the crop receiving member 24 in the measuring device 17, the control unit knows that the crops N are placed from the detection result of the load cell 19. Immediately, the weight and sugar acidity of the crop N to be measured are measured. Then, it is determined which rank corresponds to the measurement result. Although not shown, at this time, the measurement result (rank) and the completion of measurement are displayed on the operation panel unit 17A of the measurement device 17.

計測が終了すると、エアーシリンダ３５を伸長操作させて計測済みの農作物Ｎを搬送コンベア２の載置部材１０に向けて放出する。このとき、搬送コンベア２における電動モータ６の回転状態をロータリーエンコーダ４４にて計測して、農作物Ｎを載置してからの載置部材１０の移動距離を管理するようになっており、計測装置１７にて計測されたランクに対応する回収容器３に農作物Ｎが到達したことを判別すると、その箇所におけるソレノイド１６を作動させて係止部材１２を傾斜姿勢に切り換えて、農作物Ｎを載置している載置部材１０を傾斜姿勢に姿勢変更させて、農作物Ｎを回収容器３に放出させるのである。
このような選別回収作業を繰り返して実行することにより、多数の農作物Ｎを複数のランク毎に仕分けて収集することができる。 When the measurement is completed, the air cylinder 35 is extended to release the measured crop N toward the placement member 10 of the conveyor 2. At this time, the rotation state of the electric motor 6 in the conveyor 2 is measured by the rotary encoder 44, and the moving distance of the placing member 10 after the crop N is placed is managed. When it is determined that the crop N has reached the collection container 3 corresponding to the rank measured in 17, the solenoid 16 at that location is operated to switch the locking member 12 to the inclined posture, and the crop N is placed. The posture of the mounting member 10 is changed to an inclined posture, and the crop N is discharged into the collection container 3.
By repeatedly executing such sorting and collecting operations, a large number of crops N can be sorted and collected for each of a plurality of ranks.
