Description

本発明は、農作物の品質を測定する農作物品質測定装置に関する。   The present invention relates to a crop quality measuring apparatus for measuring the quality of crops.

従来から、果実や野菜を始めとした農作物に含まれる糖度等を非破壊で測定する装置が知られている。この種の装置は、農作物に赤外光等を照射し、その透過光を分析することによって、当該農作物に含まれる糖度等を測定することができる。特許文献1は、この種の果菜類品質測定装置を開示する。   2. Description of the Related Art Conventionally, there are known devices that measure sugar content and the like contained in agricultural products such as fruits and vegetables in a non-destructive manner. This type of apparatus can measure the sugar content and the like contained in the crop by irradiating the crop with infrared light and analyzing the transmitted light. Patent document 1 discloses this kind of fruit vegetable quality measuring apparatus.

特許文献1が開示する果菜類品質測定装置は、搬送手段と、測定光照射手段と、受光部と、遮光手段と、光分析装置と、を備える。搬送手段は、ベルトコンベア等であり、果菜類を搬送するために用いられる。測定光照射手段は、搬送される果菜類と同等の高さに配置されており、果菜類の側面に測定用の光を照射する。受光部は、搬送される果菜類の上方に配置されており、果菜類を上方へ透過した光を受光する。遮光手段は、農作物を透過せずに受光部に向かう光を遮断する。光分析装置は、受光部によって受光された光を分析して、果菜類の糖度等を検出する。   The fruit and vegetable quality measuring apparatus disclosed in Patent Document 1 includes a conveying unit, a measuring light irradiation unit, a light receiving unit, a light blocking unit, and an optical analyzer. A conveyance means is a belt conveyor etc., and is used in order to convey fruit vegetables. The measuring light irradiation means is arranged at the same height as the fruits and vegetables to be conveyed, and irradiates the side surfaces of the fruits and vegetables with light for measurement. The light receiving unit is disposed above the fruits and vegetables to be transported, and receives light transmitted through the fruits and vegetables. The light blocking means blocks light traveling toward the light receiving unit without passing through the crops. The optical analysis device analyzes the light received by the light receiving unit and detects the sugar content and the like of the fruit vegetables.

これにより、搬送手段によって搬送される果菜類の品質を非破壊で測定することができる。   Thereby, the quality of the fruit vegetables conveyed by a conveyance means can be measured nondestructively.

また、特許文献1に示す遮光手段は、1対の円板状の駆動回転体で構成されている。駆動回転体は、受光部を挟んで向かい合うようにして配置されている。また、駆動回転体の外周部にはブラシ部が形成されている。駆動回転体は、このブラシ部を果菜類の上面に接触させた状態で、搬送手段の搬送速度と同期して回転するように構成されている。   Moreover, the light shielding means shown in Patent Document 1 is composed of a pair of disk-shaped drive rotating bodies. The drive rotator is disposed so as to face each other with the light receiving portion interposed therebetween. Further, a brush portion is formed on the outer peripheral portion of the drive rotating body. The drive rotator is configured to rotate in synchronization with the transport speed of the transport means in a state where the brush portion is in contact with the upper surface of the fruit and vegetables.

この構成により、ブラシ部を果菜類と接触させることで、当該ブラシ部と果菜類との間に隙間が発生することを防止できる。従って、投光部から果菜類を透過せずに受光部へ向かう光を適切に遮ることができる。また、駆動回転体を搬送手段と同期回転させることにより、果菜類がブラシ部に擦られることを防止して、当該果菜類の損傷を抑えることができる。   With this configuration, it is possible to prevent a gap from being generated between the brush portion and the fruits and vegetables by bringing the brush portion into contact with the fruits and vegetables. Accordingly, it is possible to appropriately block the light traveling from the light projecting unit to the light receiving unit without passing through the fruits and vegetables. In addition, by rotating the drive rotator synchronously with the conveying means, it is possible to prevent the fruits and vegetables from being rubbed against the brush portion, and to prevent damage to the fruits and vegetables.

しかし、特許文献1の果菜類品質測定装置では、果菜類にブラシ部が直接接触するため、果菜類の表面に傷が付いたり、果菜類の品質が劣化してしまうことがある。   However, in the fruit vegetable quality measuring apparatus of Patent Document 1, since the brush part is in direct contact with the fruit vegetables, the surface of the fruit vegetables may be damaged or the quality of the fruit vegetables may deteriorate.

また、特許文献1の構成では、駆動回転体を駆動するためのモータが必要になるとともに、このモータを搬送手段と同期させて回転する制御が必要になる。そのため、構成が複雑になってしまい、装置コストが増大してしまう。   Further, in the configuration of Patent Document 1, a motor for driving the drive rotating body is required, and control for rotating the motor in synchronization with the conveying unit is required. This complicates the configuration and increases the device cost.

本発明は以上の事情に鑑みてされたものであり、その主要な目的は、投光部から果菜類を透過せずに受光部へ向かう光を簡単な構成で遮断可能であるとともに、農作物を損傷させない構成の農作物品質測定装置を提供することにある。   The present invention has been made in view of the above circumstances, and its main purpose is to block light traveling from the light projecting unit to the light receiving unit without passing through the fruits and vegetables with a simple configuration, An object of the present invention is to provide a crop quality measuring device having a structure that does not cause damage.

課題を解決するための手段及び効果Means and effects for solving the problems

本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段とその効果を説明する。   The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

本発明の観点によれば、以下の構成の農作物品質測定装置が提供される。即ち、この農作物品質測定装置は、収容容器と、搬送部と、投光部と、受光部と、遮光部と、を備える。前記収容容器は、農作物を入れるためのものである。前記搬送部は、農作物が入れられた前記収容容器を搬送する。前記投光部は、前記搬送部により搬送される前記収容容器内の農作物に照射光を照射する。前記受光部は、前記投光部による照射光が農作物を透過した光であって、前記投光部による照射光と進行方向が異なる光である測定対象光を受光する。前記遮光部は、農作物を透過せずに前記投光部から前記受光部へ向かう光を遮断可能な位置に配置され、前記搬送部により搬送される前記収容容器と接触して当該収容容器から力を受けることによって回転する。前記収容容器の側面には、前記投光部による照射光、又は農作物を透過した測定対象光を通過させるための切欠き部が形成されている。   According to the viewpoint of this invention, the crop quality measuring apparatus of the following structures is provided. That is, this crop quality measuring device includes a storage container, a transport unit, a light projecting unit, a light receiving unit, and a light shielding unit. The container is for containing agricultural products. The said conveyance part conveys the said storage container in which agricultural products were put. The light projecting unit irradiates the crops in the storage container transported by the transport unit with irradiation light. The light receiving unit receives light to be measured, which is light in which the light emitted from the light projecting unit is transmitted through a crop, and the traveling direction is different from the light emitted from the light projecting unit. The light shielding unit is disposed at a position where light from the light projecting unit to the light receiving unit can be blocked without passing through the crops, and is in contact with the storage container transported by the transport unit to force from the storage container. Rotate by receiving. A cutout portion is formed on the side surface of the container to allow the irradiation light from the light projecting unit or the measurement target light transmitted through the crop to pass therethrough.

これにより、収容容器に切欠き部が形成されているので、遮光部と収容容器とが接触している状態においても、この切欠き部を通して農作物に照射光を照射する(又は測定対象光を受光する)ことができる。また、収容容器(パン等)と接触することで遮光部が回転するため、遮光部を回転駆動するモータ等が不要となる。従って、構成を簡素化してコストを低減することができる。また、遮光部と農作物との接触が通常は起こらないため、農作物の損傷を防止できる。   As a result, the cutout portion is formed in the storage container. Therefore, even when the light shielding portion and the storage container are in contact with each other, the crop is irradiated with irradiation light (or the measurement target light is received) through the cutout portion. can do. In addition, since the light shielding portion rotates by contact with the storage container (pan or the like), a motor or the like that rotationally drives the light shielding portion becomes unnecessary. Therefore, the configuration can be simplified and the cost can be reduced. In addition, since the contact between the light-shielding portion and the crop does not normally occur, the crop can be prevented from being damaged.

前記の農作物品質測定装置においては、以下の構成とすることが好ましい。即ち、前記遮光部の少なくとも外周部は遮光性及び弾性を有する素材によって構成されている。前記搬送部による前記収容容器の搬送途中において、前記外周部が前記収容容器から力を受けて潰れるように弾性変形する。   The crop quality measuring apparatus preferably has the following configuration. That is, at least the outer peripheral portion of the light shielding portion is made of a material having light shielding properties and elasticity. During the conveyance of the storage container by the transport unit, the outer peripheral portion is elastically deformed so as to be crushed by receiving a force from the storage container.

これにより、収容容器の形状に個体差がある場合においても、遮光部の外周部の弾性変形によって、この個体差を吸収することができる。従って、例えば収容容器が通常よりも大きい場合でも、収容容器が遮光部に引っ掛かることない。一方、収容容器が通常よりも小さい場合でも、外周部の潰れ量が小さくなるだけであり、遮光部と収容容器との間に隙間が発生しない。また、容易に変形する素材(スポンジ等)で外周部を構成することにより、当該外周部と農作物とが仮に接触しても、当該農作物が損傷することを防止できる。また、切欠き部の形成箇所が外周部に食い込むため、収容容器から遮光部へ力を滑りなく伝達し、遮光部の円滑な回転を実現することができる。   Thereby, even when there is an individual difference in the shape of the container, the individual difference can be absorbed by elastic deformation of the outer peripheral portion of the light shielding portion. Therefore, for example, even when the storage container is larger than usual, the storage container is not caught by the light shielding portion. On the other hand, even when the storage container is smaller than usual, only the crushing amount of the outer peripheral part is reduced, and no gap is generated between the light shielding part and the storage container. In addition, by configuring the outer peripheral portion with a material (sponge or the like) that easily deforms, even if the outer peripheral portion and the crop are in contact with each other, the crop can be prevented from being damaged. In addition, since the notch portion is formed in the outer peripheral portion, the force can be transmitted from the storage container to the light shielding portion without slipping, and the light shielding portion can be smoothly rotated.

前記の農作物品質測定装置においては、以下の構成とすることが好ましい。即ち、この農作物品質測定装置は、互いに向かい合うように配置された2つの前記遮光部を備える。前記投光部又は前記受光部は、2つの前記遮光部の間であって、当該遮光部の端部近傍に配置される。   The crop quality measuring apparatus preferably has the following configuration. That is, this crop quality measuring apparatus includes the two light-shielding portions arranged so as to face each other. The light projecting unit or the light receiving unit is disposed between the two light shielding units and in the vicinity of the end of the light shielding unit.

これにより、農作物の上方に投光部(又は受光部)が配置され、かつ、農作物と同等の高さに複数の受光部(又は投光部)が配置される構成(即ち、農作物品質測定装置に一般的に採用される構成)に、本発明を適用することができる。   Thereby, the structure (namely, crop quality measurement apparatus) by which a light projection part (or light-receiving part) is arrange | positioned above a crop, and a some light-receiving part (or light projection part) is arrange | positioned in the height equivalent to a crop The present invention can be applied to a configuration generally adopted in the above.

前記の農作物品質測定装置においては、2つの前記遮光部は、前記投光部又は前記受光部に近づくに従って、前記遮光部同士が離れるように配置されることが好ましい。   In the said crop quality measuring apparatus, it is preferable that two said light-shielding parts are arrange | positioned so that the said light-shielding parts may leave | separate as it approaches the said light projection part or the said light-receiving part.

これにより、投光部又は受光部を配置するためのスペースを大きく確保することが可能となるので、コンパクトな農作物品質測定装置を実現できる。   Thereby, a large space for arranging the light projecting unit or the light receiving unit can be ensured, so that a compact crop quality measuring device can be realized.

The belt driving unit 32 includes a motor (not shown), and the conveyor belt 31 can be moved by the driving force of the motor. The driving force generated by this motor is first transmitted to the drive shaft 33 shown in FIG. Further, as shown in FIG. 2, a driven shaft 37 is rotatably attached to the wall surface of the belt drive unit 32 and obliquely above the upstream side of the drive shaft 33.

1対のフレーム12の間であって、当該フレーム12の上流側の端部近傍には、従動軸35が回動可能に取り付けられている。一方、1対のフレーム12の間であって、当該フレーム12の下流側の端部近傍には、従動軸34が回動可能に取り付けられている。また、図2に示すように、1対のフレーム12の間であって、ベルト駆動部32のやや上流側には、従動軸36が回動可能に取り付けられている。   A driven shaft 35 is rotatably mounted between the pair of frames 12 and in the vicinity of the upstream end of the frame 12. On the other hand, a driven shaft 34 is rotatably attached between the pair of frames 12 and in the vicinity of the downstream end of the frame 12. As shown in FIG. 2, a driven shaft 36 is rotatably attached between the pair of frames 12 and slightly upstream of the belt drive unit 32.

上記の駆動軸33及び従動軸34〜37には、搬送ベルト31が巻き掛けられる。そして、モータの駆動力によって駆動軸33を図2に示す方向に回転させることにより、パン70及び農作物80を上流側から下流側へ移動させる方向に搬送ベルト31を動かすことができる。   A conveyor belt 31 is wound around the drive shaft 33 and the driven shafts 34 to 37. Then, by rotating the drive shaft 33 in the direction shown in FIG. 2 by the driving force of the motor, the conveyance belt 31 can be moved in the direction in which the bread 70 and the crop 80 are moved from the upstream side to the downstream side.

As shown in FIG. 2, the column portion 24 is a member that extends upward from a horizontal surface 22 c formed inside the housing 22. As shown in FIG. 4, a pair of pillar portions 24 facing each other are arranged in the housing 22, and the upper portions of the pillar portions 24 are connected to each other by a connection plate 25. Further, as shown in FIGS. 3 and 4, a crank-shaped member 27 and a light receiving portion mounting member 29 are respectively attached to the pair of column portions 24. That is, the crop quality measuring device 1 includes two crank-shaped members 27 and two light receiving unit mounting members 29.

接続板25には、図3及び図4に示すように、投光部取付部材26が取り付けられている。投光部取付部材26は、1枚の平板を直角に折り曲げたL字状の部材である。投光部取付部材26は、前記L字の一辺側において、接続板25の中央部に取り付けられている。前記L字状の他辺側には、投光部44が取り付けられている。   As shown in FIGS. 3 and 4, a light projecting portion mounting member 26 is attached to the connection plate 25. The light projecting portion mounting member 26 is an L-shaped member obtained by bending a single flat plate at a right angle. The light projecting portion attaching member 26 is attached to the central portion of the connection plate 25 on one side of the L-shape. A light projecting portion 44 is attached to the other side of the L shape.

クランク状部材27は、図3に示すように、1枚の平板を2箇所折り曲げた断面クランク状の部材である。クランク状部材27は、上側(投光部側)において、柱部24に取り付けられている。また、クランク状部材27には、下側(受光部側)において、遮光円板取付部材28が取り付けられている。   As shown in FIG. 3, the crank-shaped member 27 is a crank-shaped member having a cross section obtained by bending one flat plate at two locations. The crank-shaped member 27 is attached to the column part 24 on the upper side (light projecting part side). The crank-shaped member 27 is attached with a light-shielding disc attachment member 28 on the lower side (light receiving portion side).

遮光円板取付部材28は、1枚の平板を直角に折り曲げたL字状の部材である。遮光円板取付部材28は、前記L字状の一辺側において、前記クランク状部材27に取り付けられている。前記L字状の他辺側には、遮光円板45のシャフト45aが取り付けられている。シャフト45aは、図略のベアリングを介して遮光円板45に接続されているため、遮光円板45はシャフト45aに対して自由に回転することができる。   The light shielding disc mounting member 28 is an L-shaped member obtained by bending a single flat plate at a right angle. The light-shielding disc attachment member 28 is attached to the crank-like member 27 on one side of the L-shape. A shaft 45a of a light shielding disk 45 is attached to the other side of the L shape. Since the shaft 45a is connected to the light shielding disk 45 via a bearing (not shown), the light shielding disk 45 can freely rotate with respect to the shaft 45a.

上述のように筐体22内にはクランク状部材27が2つ配置されており、図4に示すように、それぞれのクランク状部材27に遮光円板取付部材28が取り付けられている。また、2つの遮光円板取付部材28には、それぞれ遮光円板45が取り付けられている。本実施形態では、遮光円板45の回転軸線は水平ではなく傾斜している。また、2つの遮光円板45が有する回転軸線は互いに平行に配置されておらず、この結果、2つの遮光円板45は、上側(投光部側)に向かうにつれて互いの間隔が広がるように配置されている。   As described above, two crank-shaped members 27 are arranged in the housing 22, and a light-shielding disk mounting member 28 is attached to each crank-shaped member 27 as shown in FIG. 4. Further, a light shielding disk 45 is attached to each of the two light shielding disk mounting members 28. In the present embodiment, the rotation axis of the light shielding disc 45 is inclined rather than horizontal. Further, the rotation axes of the two light shielding disks 45 are not arranged in parallel to each other, and as a result, the distance between the two light shielding disks 45 increases toward the upper side (light projecting unit side). Has been placed.

この構成により、遮光円板45の上側の領域を有効に活用することができる。ただし、遮光円板45の向きは任意であり、例えば、2つの遮光円板45の回転軸線同士を一致させるように水平に配置しても良い(図6の変形例を参照)。   With this configuration, the upper region of the light shielding disk 45 can be effectively utilized. However, the direction of the light-shielding disk 45 is arbitrary, and for example, the light-shielding disks 45 may be arranged horizontally so that the rotation axes of the two light-shielding disks 45 coincide with each other (see the modification of FIG. 6).

受光部取付部材29は、1枚の平板を直角に折り曲げたL字状の部材である。受光部取付部材29は、前記L字状の一辺側において、柱部24に取り付けられている。また、前記L字状の他辺側には取付孔が形成されており、この取付孔に受光部46が取り付けられている。   The light receiving portion mounting member 29 is an L-shaped member obtained by bending a single flat plate at a right angle. The light receiving portion attachment member 29 is attached to the column portion 24 on one side of the L shape. A mounting hole is formed on the other side of the L-shape, and a light receiving portion 46 is mounted in this mounting hole.

上述のように筐体22内には受光部取付部材29が2つ配置されており、図4に示すように、それぞれの受光部取付部材29に受光部46が取り付けられている。2つの受光部46は、搬送ベルト31を挟んで同じ高さに配置されている。また、それぞれの受光部46は、搬送ベルト31の載せられたパン70の切欠き部70aと同じ高さが受光箇所となる位置に配置されている。   As described above, the two light receiving portion mounting members 29 are arranged in the housing 22, and the light receiving portions 46 are attached to the respective light receiving portion mounting members 29 as shown in FIG. 4. The two light receiving portions 46 are arranged at the same height with the conveyance belt 31 in between. Each of the light receiving portions 46 is disposed at a position where the same height as the cutout portion 70a of the pan 70 on which the transport belt 31 is placed becomes a light receiving location.

次に、図2から図5までを参照して、筐体22の内部に配置される光学機器について説明する。図5は、搬送されるパン70と遮光円板45とが接触するときの状態を示す側面図である。なお、本実施形態の農作物品質測定装置1において、筐体22内に対で配置される遮光円板45、受光部46等の構成はそれぞれ互いに同等の構成となっているため、以下の説明では、一方のみを代表して説明することがある。   Next, with reference to FIG. 2 to FIG. 5, an optical device arranged inside the housing 22 will be described. FIG. 5 is a side view showing a state when the transported pan 70 and the light-shielding disc 45 are in contact with each other. In addition, in the agricultural product quality measuring apparatus 1 of this embodiment, since the structure of the light shielding disk 45, the light-receiving part 46, etc. which are arrange | positioned in a pair in the housing | casing 22 is mutually equivalent structure, in the following description. Only one of them may be described as a representative.

測定ケース41は、図2に示すように筐体22の底面に設置されており、赤外光を出射可能な光源42と、農作物80を透過した光(透過光)を分析する光分析部48と、を備えた構成となっている。光源42には光ファイバ43が接続されており、この光ファイバ43は、光源42と、筐体22の上端近傍に配置された投光部44と、を接続している。   As shown in FIG. 2, the measurement case 41 is installed on the bottom surface of the housing 22, and a light source 42 capable of emitting infrared light and an optical analysis unit 48 that analyzes light (transmitted light) transmitted through the crop 80. And, it has a configuration comprising. An optical fiber 43 is connected to the light source 42, and the optical fiber 43 connects the light source 42 and a light projecting unit 44 disposed in the vicinity of the upper end of the housing 22.

投光部44は、上述のように、前記投光部取付部材26に取り付けられている。光源42からの光は、この投光部44から下側に向けて出射される。これにより、投光部44の下方を通過するパン70内の農作物80に、光(照射光)を照射することができる。   The light projecting unit 44 is attached to the light projecting unit mounting member 26 as described above. Light from the light source 42 is emitted downward from the light projecting unit 44. Thereby, light (irradiation light) can be irradiated to the crop 80 in the bread | pan 70 which passes under the light projection part 44. FIG.

遮光円板45は、上述のように、遮光円板取付部材28に回転可能に取り付けられている。遮光円板45は、投光部44から出射された光のうち、農作物80の表面で反射した光等が受光部46に入射しないように遮るための部材である。なお、遮光円板45の構成及び動作の詳細については後述する。   The light shielding disk 45 is rotatably attached to the light shielding disk mounting member 28 as described above. The light-shielding disk 45 is a member that shields the light emitted from the light projecting unit 44 from being reflected on the surface of the crop 80 so as not to enter the light receiving unit 46. The details of the configuration and operation of the light shielding disk 45 will be described later.

受光部46は、上述のように受光部取付部材29に取り付けられている。受光部46は、農作物80を透過した光である透過光を受光する。具体的には、図4に示すように、パン70の切欠き部70aを通過した透過光を受光する。また、受光部46は、光ファイバ47を介して、測定ケース41内の光分析部48に接続されている。   The light receiver 46 is attached to the light receiver attachment member 29 as described above. The light receiving unit 46 receives transmitted light that is light transmitted through the crop 80. Specifically, as shown in FIG. 4, the transmitted light that has passed through the notch 70a of the pan 70 is received. The light receiving unit 46 is connected to an optical analysis unit 48 in the measurement case 41 via an optical fiber 47.

光分析部48は、受光部46が受光した透過光を分析することにより、農作物の糖度を測定することができる。具体的には、赤外光のうち所定波長の光はショ糖の濃度に応じて吸収されるため、果実を透過する前後において、この所定波長の光がどの程度吸収されたかを測定することで、果実のショ糖濃度(糖度)を得ることができる。また、遮光円板45の作用により、光分析部48には、農作物80の表面で反射した光や、投光部44から直接的に受光部46へ向かう光等を遮ることができる。従って、農作物80を透過した透過光のみを分析することができるので、農作物80の糖度を精度良く測定することができる。   The light analysis unit 48 can measure the sugar content of the crop by analyzing the transmitted light received by the light receiving unit 46. Specifically, since light of a predetermined wavelength in infrared light is absorbed according to the concentration of sucrose, by measuring how much the light of the predetermined wavelength is absorbed before and after passing through the fruit, The sucrose concentration (sugar content) of the fruit can be obtained. Further, by the action of the light shielding disk 45, the light analyzing unit 48 can block light reflected by the surface of the crop 80, light directed directly from the light projecting unit 44 to the light receiving unit 46, and the like. Therefore, since only the transmitted light that has passed through the crop 80 can be analyzed, the sugar content of the crop 80 can be accurately measured.

遮光円板45は、図3に示すように、円板状に形成されている。遮光円板45は、内側(中心側)から、シャフト45aと、内側回転体45bと、外側回転体(外周部)45cと、で構成される。シャフト45aは、前記遮光円板取付部材28に回転可能に取り付けられる。内側回転体45bは、例えばウレタンゴム製の部材であり、シャフト45aの回転に従って回転する。外側回転体45cは、例えばスポンジ製の部材であり、シャフト45a及び内側回転体45bとともに回転する。   As shown in FIG. 3, the light shielding disk 45 is formed in a disk shape. The light-shielding disk 45 includes a shaft 45a, an inner rotating body 45b, and an outer rotating body (outer peripheral portion) 45c from the inner side (center side). The shaft 45a is rotatably attached to the light shielding disc attachment member 28. The inner rotating body 45b is a member made of urethane rubber, for example, and rotates according to the rotation of the shaft 45a. The outer rotating body 45c is a sponge member, for example, and rotates together with the shaft 45a and the inner rotating body 45b.

また、本実施形態における遮光円板45は、シャフト45aによって回転可能に支持されているだけであって、モータ等によって駆動されるものではない。即ち、遮光円板45は、パン70の接触面70bと接触することにより、当該パン70から力を受けて回転するようになっている。   Further, the light-shielding disc 45 in this embodiment is only supported rotatably by the shaft 45a, and is not driven by a motor or the like. That is, the light-shielding disc 45 is rotated by receiving a force from the pan 70 by contacting the contact surface 70 b of the pan 70.

以下、パン70の搬送に伴う遮光円板45の回転動作を説明する。図5に示すように、本実施形態では、パン70の上端部(即ち接触面70b)よりも、当該遮光円板45の下端部の方が下方になるようなレイアウトとなっている。   Hereinafter, the rotation operation of the light shielding disc 45 accompanying the conveyance of the pan 70 will be described. As shown in FIG. 5, in the present embodiment, the layout is such that the lower end portion of the light-shielding disc 45 is lower than the upper end portion (that is, the contact surface 70 b) of the pan 70.

そのため、図5(a)の状態から搬送ベルト31に沿ってパン70が搬送されていくと、図5(b)に示すように、パン70が外側回転体45cに接触するようになる。この状態でパン70が更に下流側に搬送されることにより、遮光円板45は、パン70から力を受けて、図5(b)に矢印で示す方向に回転する。即ち、遮光円板45は、外側回転体45cと接触面70bとの間に発生する摩擦力によって、パン70の搬送とともに回転する。このように遮光円板45を回転させることにより、パン70と遮光円板45とが擦れること(又は引っ掛かること)を回避できるので、パン70及び遮光円板45が摩耗(又は破損)することを防止できる。また、駆動装置を用いることなく遮光円板45をパン70の搬送に従って回転させることができるので、低コスト化を実現することができる。   Therefore, when the pan 70 is transported along the transport belt 31 from the state of FIG. 5A, the pan 70 comes into contact with the outer rotating body 45c as shown in FIG. 5B. In this state, the pan 70 is further conveyed to the downstream side, so that the light shielding disk 45 receives a force from the pan 70 and rotates in a direction indicated by an arrow in FIG. That is, the light shielding disk 45 rotates with the conveyance of the pan 70 by the frictional force generated between the outer rotating body 45c and the contact surface 70b. Since the pan 70 and the light-shielding disk 45 can be prevented from rubbing (or caught) by rotating the light-shielding disk 45 in this manner, the pan 70 and the light-shielding disk 45 can be worn (or damaged). Can be prevented. Moreover, since the light shielding disk 45 can be rotated according to the conveyance of the pan 70 without using a driving device, cost reduction can be realized.

なお、遮光円板45の外側回転体45cはスポンジ製であるため、パン70が遮光円板45の下方を搬送される過程において、当該外側回転体45cは、図5(b)及び図5(c)に示すように、パン70から力を受けて容易に弾性変形する。このように遮光円板45が接触面70bに対して密着するので、確実な遮光を実現し、糖度を正確に測定することができる。また、パン70の高さに多少の個体差(バラツキ)があった場合でも、外側回転体45cの弾性変形によって当該個体差を吸収して、遮光円板45の適切な回転及び遮光効果を維持することができる。   Since the outer rotating body 45c of the light shielding disk 45 is made of sponge, the outer rotating body 45c is shown in FIGS. 5B and 5 (B) in the process in which the pan 70 is conveyed below the light shielding disk 45. As shown in c), it is easily elastically deformed by receiving a force from the pan 70. Thus, since the light-shielding disk 45 adheres with respect to the contact surface 70b, reliable light-shielding is implement | achieved and sugar content can be measured correctly. Even if there is some individual difference (variation) in the height of the pan 70, the individual difference is absorbed by the elastic deformation of the outer rotating body 45c, and the appropriate rotation and light shielding effect of the light shielding disk 45 is maintained. can do.

図5(c)は、図5(b)に示す状態からパン70が更に下流側に搬送されて、遮光円板45の真下(即ち投光部44の真下)に位置した様子を示している。この図5(c)の状態が図4に対応しており、この状態で糖度の測定が行われる。このときは図5(c)に示すように、遮光円板45の外側回転体45cが切欠き部70aの内部に向けて膨らむように突出しているが、切欠き部70aを完全に塞ぐことはないので、受光部46は、農作物80を透過した光を問題なく受光することができる。   FIG. 5C shows a state where the pan 70 is conveyed further downstream from the state shown in FIG. 5B and is located directly under the light shielding disk 45 (ie, directly under the light projecting portion 44). . The state of FIG. 5 (c) corresponds to FIG. 4, and the sugar content is measured in this state. At this time, as shown in FIG. 5C, the outer rotating body 45c of the light-shielding disk 45 protrudes so as to swell toward the inside of the notch 70a, but the notch 70a is not completely blocked. Therefore, the light receiving unit 46 can receive the light transmitted through the crop 80 without any problem.

また、図5(c)のタイミングにおいては、パン70に形成された切欠き部70aの境界部分が遮光円板45に食い込んでいる。従って、パン70の搬送によって、遮光円板45を滑りなく確実に回転させることができる。   In addition, at the timing of FIG. 5C, the boundary portion of the notch portion 70 a formed in the pan 70 bites into the light shielding disc 45. Therefore, the light shielding disk 45 can be reliably rotated without slipping by the conveyance of the pan 70.

また、図4に示すように、対で配置された遮光円板45の下端部同士の間隔は、円筒状のパン70の外径とほぼ等しくなっており、当該パン70の内径(農作物80の大きさ)よりは若干大きくなっている。従って、通常は、農作物80が遮光円板45に直接接触することはないので(図4を参照)、農作物80の品質を好適に保つことができる。ただし、例えば振動が加わった場合には、農作物80が遮光円板45に接触することも考えられるが、上記のように外側回転体45cが弾性変形可能であるので、当該農作物80の損傷も防止することができる。   As shown in FIG. 4, the distance between the lower ends of the light shielding disks 45 arranged in pairs is substantially equal to the outer diameter of the cylindrical pan 70, and the inner diameter of the pan 70 (the crop 80). It is slightly larger than (size). Therefore, normally, since the crop 80 does not directly contact the light-shielding disk 45 (see FIG. 4), the quality of the crop 80 can be suitably maintained. However, for example, when vibration is applied, the crop 80 may come into contact with the light-shielding disk 45. However, the outer rotating body 45c can be elastically deformed as described above, so that the crop 80 is also prevented from being damaged. can do.

以上に説明したように、本実施形態の農作物品質測定装置1は、パン70と、搬送ベルト31と、投光部44と、受光部46と、遮光円板45と、を備える。パン70は、農作物80を入れるためのものである。搬送ベルト31は、農作物80が入れられたパン70を搬送する。投光部44は、搬送ベルト31により搬送されるパン70内の農作物80に照射光を照射する。受光部46は、投光部44による照射光が農作物80を透過した光であって、投光部44による照射光と進行方向が異なる光である測定対象光を受光する。遮光円板45は、農作物80を透過せずに投光部44から受光部46へ向かう光を遮断可能な位置に配置され、搬送ベルト31により搬送されるパン70と接触して当該パン70から力を受けることによって回転する。パン70の側面には、投光部44による照射光、又は農作物80を透過した測定対象光を通過させるための切欠き部70aが形成されている。   As described above, the crop quality measuring apparatus 1 according to the present embodiment includes the bread 70, the conveyance belt 31, the light projecting unit 44, the light receiving unit 46, and the light shielding disk 45. The bread 70 is for putting the crop 80. The conveyor belt 31 conveys the bread 70 in which the crop 80 is put. The light projecting unit 44 irradiates the crop 80 in the bread 70 conveyed by the conveyance belt 31 with irradiation light. The light receiving unit 46 receives light to be measured, which is light that is emitted from the light projecting unit 44 through the crop 80 and has a traveling direction different from that of the light emitted from the light projecting unit 44. The light shielding disk 45 is disposed at a position where light from the light projecting unit 44 to the light receiving unit 46 can be blocked without passing through the crop 80, and comes into contact with the pan 70 conveyed by the conveyance belt 31. It rotates by receiving force. On the side surface of the pan 70, a notch 70 a for allowing the light irradiated by the light projecting unit 44 or the measurement target light transmitted through the crop 80 to pass therethrough is formed.

これにより、パン70に切欠き部70aが形成されているので、遮光円板45とパン70とが接触している状態においても、この切欠き部70aを通して測定対象光を受光することができる。また、パン70と接触することで遮光円板45が回転するため、遮光円板45を回転駆動するモータ等が不要となる。従って、構成を簡素化してコストを低減することができる。また、遮光円板45と農作物80との接触が通常は起こらないため、農作物80の損傷を防止できる。   Thereby, since the notch part 70a is formed in the pan 70, the measurement target light can be received through the notch part 70a even when the light shielding disc 45 and the pan 70 are in contact with each other. Further, since the light shielding disk 45 rotates by contacting the pan 70, a motor or the like for rotating the light shielding disk 45 becomes unnecessary. Therefore, the configuration can be simplified and the cost can be reduced. Further, since the contact between the light-shielding disc 45 and the crop 80 does not normally occur, the crop 80 can be prevented from being damaged.

また、本実施形態の農作物品質測定装置1においては、遮光円板45の少なくとも外側回転体45cは遮光性及び弾性を有する素材によって構成されている。搬送ベルト31によるパン70の搬送途中において、外側回転体45cがパン70から力を受けて潰れるように弾性変形する。   In the crop quality measuring apparatus 1 of the present embodiment, at least the outer rotating body 45c of the light shielding disk 45 is made of a material having light shielding properties and elasticity. During the conveyance of the pan 70 by the conveyance belt 31, the outer rotating body 45 c is elastically deformed so as to be crushed by receiving a force from the pan 70.

これにより、パン70の形状に個体差がある場合においても、外側回転体45cの弾性変形によって、この個体差を吸収することができる。また、本実施形態では、容易に変形するスポンジで外側回転体45cが構成されているため、当該外側回転体45cと農作物80とが仮に接触しても、当該農作物80が損傷することを防止できる。また、切欠き部70aの搬送方向上流側の端部に外側回転体45cが食い込むため、当該外側回転体45cから遮光円板45へ力を伝達し易くすることができる。   Thereby, even when there is an individual difference in the shape of the pan 70, the individual difference can be absorbed by the elastic deformation of the outer rotating body 45c. Further, in the present embodiment, since the outer rotating body 45c is configured by a sponge that easily deforms, even if the outer rotating body 45c and the crop 80 are in contact with each other, the crop 80 can be prevented from being damaged. . Further, since the outer rotator 45c bites into the upstream end of the notch 70a in the conveying direction, it is possible to easily transmit force from the outer rotator 45c to the light shielding disc 45.

また、本実施形態の農作物品質測定装置1においては、互いに向かい合うように配置された2つの遮光円板45を備える。投光部44は、2つの遮光円板45の間であって、当該遮光円板45の(上側の)端部近傍に配置される。   In addition, the crop quality measuring device 1 of the present embodiment includes two light shielding disks 45 arranged to face each other. The light projecting unit 44 is disposed between the two light shielding disks 45 and in the vicinity of the (upper) end of the light shielding disk 45.

これにより、農作物の上方に投光部44が配置され、かつ、農作物と同等の高さに2つの受光部46が配置された本実施形態の構成(一般的な構成)において、上記の効果を発揮させることができる。   Thereby, in the configuration (general configuration) of the present embodiment in which the light projecting unit 44 is disposed above the crop and the two light receiving units 46 are disposed at the same height as the crop, the above-described effect is obtained. It can be demonstrated.

また、本実施形態の農作物品質測定装置1においては、2つの遮光円板45は、投光部44に近づくに従って、遮光円板45同士が離れるように配置される。   In the crop quality measuring apparatus 1 of the present embodiment, the two light shielding disks 45 are arranged so that the light shielding disks 45 are separated from each other as the light projecting unit 44 is approached.

これにより、投光部44を配置するためのスペースを大きく確保することが可能となるので、コンパクトな農作物品質測定装置1を実現できる。   As a result, a large space for arranging the light projecting unit 44 can be secured, so that the compact agricultural product quality measuring apparatus 1 can be realized.

以上に本発明の好適な実施の形態を説明したが、上記の構成は例えば以下のように変更することができる。   The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

遮光円板45に加え、シャッタ部材を投光部44の下方に配置しても良い。シャッタ部材とは、当該投光部44から出射された光によって農作物80が照射されないように当該光を遮る位置と、投光部44から出射された光によって農作物80が照射されるように退避した位置と、の間で位置を切替可能に構成される部材である。   In addition to the light shielding disk 45, a shutter member may be disposed below the light projecting portion 44. The shutter member is a position that blocks the light so that the crop 80 is not irradiated with the light emitted from the light projecting unit 44, and the shutter member is retracted so that the crop 80 is irradiated with the light emitted from the light projecting unit 44. It is a member configured to be able to switch positions between positions.

内側回転体45b及び外側回転体45cは、遮光性を有する素材であれば、他の素材で構成されていても良い。また、外側回転体45cは、上述の効果(パン70の個体差を吸収すること及び農作物80を損傷させないこと)を発揮させるために、弾性を有するとともに変形し易い素材であることが好ましい。   The inner rotator 45b and the outer rotator 45c may be made of other materials as long as they have a light shielding property. The outer rotating body 45c is preferably made of a material that has elasticity and is easily deformed in order to exhibit the above-described effects (absorbing individual differences of the bread 70 and not damaging the crop 80).

上記実施形態の構成に代えて、例えば、搬送される農作物80と同程度の高さに投光部を配置し、当該農作物80の上方に受光部を配置する構成にしても良い。また、搬送される農作物80と同程度の高さに配置される投光部又は受光部の個数は2個に限られず、1個、又は3個以上とすることができる。   Instead of the configuration of the above-described embodiment, for example, a light projecting unit may be arranged at the same height as the conveyed crop 80 and a light receiving unit may be arranged above the crop 80. Further, the number of light projecting units or light receiving units arranged at the same height as the conveyed crop 80 is not limited to two, and may be one, or three or more.

パン70については、投光部による照射光又は農作物を透過した測定対象光を通過させることが可能な切欠き部が形成されている限り、その形状を任意に変更することができる。   The shape of the pan 70 can be arbitrarily changed as long as a cutout portion capable of transmitting the light irradiated by the light projecting unit or the measurement target light transmitted through the crop is formed.
