Description

本発明は、例えば、パイナップルに生じる黒目病など外観からは判別が困難で、かつ、青果物内部において部分的に生じる内部品質を非破壊で検査するための内部品質検査装置に関する。 The present invention relates to an internal quality inspection device for non-destructively inspecting the internal quality partially generated inside fruits and vegetables, which is difficult to distinguish from the appearance such as black eye disease occurring in pineapple.

従来、果実や野菜などの青果物の内部品質を非破壊的に検査する方法として、近赤外分光法が知られている。
近赤外分光法は、例えば、特許文献1,2に開示されるように、青果物に対して近赤外光の波長帯域を含む光を照射し、青果物を透過した透過光及び/又は青果物を反射した反射光を受光することによって、青果物による光強度の減少(光の吸収)に基づいて、その青果物の品質(特性)を測定するものである。
Conventionally, near-infrared spectroscopy has been known as a method for non-destructively inspecting the internal quality of fruits and vegetables such as fruits and vegetables.
In near-infrared spectroscopy, for example, as disclosed in Patent Documents 1 and 2, fruits and vegetables are irradiated with light including a wavelength band of near-infrared light, and transmitted light and / or fruits and vegetables transmitted through the fruits and vegetables are emitted. By receiving the reflected reflected light, the quality (characteristics) of the fruits and vegetables is measured based on the decrease in light intensity (light absorption) caused by the fruits and vegetables.

内部品質の有無に応じて、光強度の減少が生じる波長やその大小が異なっているため、青果物の内部品質を検査するために、近赤外分光法を用いることで、簡単かつ正確に、青果物の内部品質の有無を検査することができる。 Since the wavelength and magnitude of the decrease in light intensity differ depending on the presence or absence of internal quality, near-infrared spectroscopy can be used to easily and accurately inspect the internal quality of fruits and vegetables. Can be inspected for internal quality.

特に、空洞果など青果物の内部において、局所的に発生する内部品質を検出するためには、特許文献2〜5に開示されるように、複数の光源から近赤外光を照射するとともに、複数の受光部により青果物を透過した透過光を検出することによって、検出漏れを無くすようにしている。 In particular, in order to detect the internal quality locally generated inside fruits and vegetables such as hollow fruits, as disclosed in Patent Documents 2 to 5, near-infrared light is irradiated from a plurality of light sources and a plurality of sources are irradiated. By detecting the transmitted light transmitted through the fruits and vegetables by the light receiving part of the above, the detection omission is eliminated.

特開2014−174030号公報Japanese Unexamined Patent Publication No. 2014-174030 特開2006−98106号公報Japanese Unexamined Patent Publication No. 2006-98106 特開平6−288903号公報Japanese Unexamined Patent Publication No. 6-288903 国際公開第01/022062号International Publication No. 01/022062 国際公開第05/108956号International Publication No. 05/108956

しかしながら、特許文献2〜5に開示されるような複数の光源を用いた場合であっても、受光部により検出された透過光は、青果物全体の平均値に対応するものであった。このため、青果物の糖度や酸度などや、例えば、長物、楕円球状の青果物の内部に生じる空洞など、特定箇所に生じる内部障害については検出することができていたが、青果物内部において局所的に生じる、例えば、パイナップルの黒目病などの内部障害を検出することは困難であった。 However, even when a plurality of light sources as disclosed in Patent Documents 2 to 5 are used, the transmitted light detected by the light receiving unit corresponds to the average value of all fruits and vegetables. For this reason, it was possible to detect the sugar content and acidity of fruits and vegetables, and internal disorders that occur in specific places such as long objects and cavities that occur inside elliptical spherical fruits and vegetables, but they occur locally inside fruits and vegetables. For example, it has been difficult to detect internal disorders such as pineapple black eye disease.

本発明では、このような現状に鑑み、例えば、パイナップルに生じる黒目病など、青果物内部において、不特定箇所に生じる内部障害を含む、青果物の内部品質を非破壊で検査することができる内部品質検査装置を提供することを目的とする。 In view of this situation, the present invention allows non-destructive inspection of the internal quality of fruits and vegetables, including internal disorders that occur in unspecified places inside the fruits and vegetables, such as black eye disease that occurs in pineapple. The purpose is to provide the device.

以下、本発明の実施の形態(実施例)を図面に基づいて、より詳細に説明する。
図1は、本実施形態の内部品質検査装置の構成を示す平面図、図2は、図1のA−A線における断面図である。
Hereinafter, embodiments (examples) of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a plan view showing the configuration of the internal quality inspection device of the present embodiment, and FIG. 2 is a cross-sectional view taken along the line AA of FIG.

図1,2に示すように、本実施形態の内部品質検査装置10は、青果物Tを所定方向に搬送する搬送手段12と、搬送手段12の側方及び上方に略円環状に設けられた複数の投光手段14a〜14hと、搬送手段12の下方に設けられた受光手段16と、受光手段16により受光した光強度に基づき青果物Tの検査処理を行う演算処理手段18と、を備えている。 As shown in FIGS. 1 and 2, the internal quality inspection device 10 of the present embodiment includes a transport means 12 for transporting fruits and vegetables T in a predetermined direction, and a plurality of transport means 12 provided in a substantially annular shape on the side and above of the transport means 12. The light projecting means 14a to 14h, the light receiving means 16 provided below the transporting means 12, and the arithmetic processing means 18 for inspecting the fruits and vegetables T based on the light intensity received by the light receiving means 16. ..

搬送手段12は、青果物Tを所定方向に搬送可能なものであって、搬送手段12の下方に設けられた受光手段16に、青果物Tを透過した検査光(透過光)が受光可能なように構成されている。このような搬送手段12として、本実施形態では、図2に示すような、穴あきトレー12aを用いたトレーコンベアを用いているが、これに限らず、例えば、青果物Tの大きさよりも小さい幅だけ離間して配置された2条のベルトコンベアであってもよい。 The transporting means 12 is capable of transporting the fruits and vegetables T in a predetermined direction so that the light receiving means 16 provided below the transporting means 12 can receive the inspection light (transmitted light) transmitted through the fruits and vegetables T. It is configured. As such a transporting means 12, in the present embodiment, a tray conveyor using a perforated tray 12a as shown in FIG. 2 is used, but the present invention is not limited to this, and for example, a width smaller than the size of the fruit and vegetable T is used. It may be a two-row belt conveyor arranged only apart from each other.

投光手段14a〜14hはそれぞれ、青果物Tに対して照射形状が略方形となるように整形された検査光を照射するように構成される。そして、略円環状に配置された投光手段14a〜14hから検査光を照射することによって、図2,3に示すように、青果物Tの略半周に亘って、検査光が照射(検査光の照射領域M)されることとなる。 Each of the light projecting means 14a to 14h is configured to irradiate the fruits and vegetables T with inspection light shaped so that the irradiation shape is substantially square. Then, by irradiating the inspection light from the light projecting means 14a to 14h arranged in a substantially annular shape, the inspection light is irradiated (inspection light) over substantially half of the circumference of the fruit and vegetable T as shown in FIGS. Irradiation area M) will be applied.

本実施形態では、複数の投光手段14a〜14hを用いて青果物Tの略半周に亘って、検査光を照射するようにしているが、例えば、LEDアレイなどからなる1つの投光手段によって照射するようにしても構わない。 In the present embodiment, a plurality of light projecting means 14a to 14h are used to irradiate the inspection light over substantially half of the circumference of the fruit and vegetable T. For example, the light projecting means is irradiated by one light projecting means including an LED array or the like. You may try to do it.

投光手段14a〜14hとしては、検査光として、400〜1700nmの波長を含む光、より好ましくは、500〜1100nmの波長を含む光を照射することができるものであれば、特に限定されるものではないが、光源として、例えば、ハロゲンランプ、ナトリウムランプ、蛍光管、ネオン管、LED(Light Emitting Diode)、レーザー光源などを用いることができ、また、波長可変光源を用いてもよい。 The light projecting means 14a to 14h are particularly limited as long as they can irradiate light having a wavelength of 400 to 1700 nm, more preferably light having a wavelength of 500 to 1100 nm, as inspection light. However, as the light source, for example, a halogen lamp, a sodium lamp, a fluorescent tube, a neon tube, an LED (Light Emitting Diode), a laser light source, or the like can be used, or a variable wavelength light source may be used.

投光手段14a〜14hの光源として、ハロゲンランプなど光束が拡散する光源を用いる場合には、スリットやコリメーターなどの光学系(図示せず)によって、光束を整形し、照射形状が、搬送方向における青果物Tの幅よりも細い帯状となるように調整するように構成される。 When a light source such as a halogen lamp that diffuses a luminous flux is used as the light source of the light projecting means 14a to 14h, the luminous flux is shaped by an optical system (not shown) such as a slit or a collimator, and the irradiation shape is changed in the transport direction. It is configured to be adjusted so as to have a band shape narrower than the width of the fruit and vegetable T in the above.

受光手段16としては、このような検査光を受光可能なものであれば、特に限定されるものではなく、例えば、Si、InGaAs、Ge、PbSなどのフォトダイオードであってもよいし、また、これらのフォトダイオードを用いたエリアカメラ、ラインカメラ、分光器、イメージング分光器、マルチバンドカメラなどを用いることができる。 The light receiving means 16 is not particularly limited as long as it can receive such inspection light, and may be, for example, a photodiode such as Si, InGaAs, Ge, or PbS. Area cameras, line cameras, spectroscopes, imaging spectroscopes, multi-band cameras and the like using these photodiodes can be used.

演算処理手段18は、投光手段14a〜14h及び受光手段16の動作を制御するとともに、受光手段16によって取得された測定値に基づき、青果物Tの検査を行う。このような演算処理手段18としては、例えば、演算手段、記憶手段、通信手段などを有するコンピュータとすることができ、パーソナルコンピュータ、ワークステーション、汎用サーバなどであってもよいし、マイクロコントローラなどの形態とすることもできる。 The arithmetic processing means 18 controls the operations of the light emitting means 14a to 14h and the light receiving means 16, and inspects the fruits and vegetables T based on the measured values acquired by the light receiving means 16. The arithmetic processing means 18 may be, for example, a computer having an arithmetic means, a storage means, a communication means, or the like, and may be a personal computer, a workstation, a general-purpose server, or the like, or a microcontroller or the like. It can also be in the form.

なお、演算処理手段18は、受光手段16によって取得された測定値、すなわち、透過光の光量値をそのまま用いて検査を行ってもよいし、例えば、受光手段16として分光機能を有するものを用いている場合には、透過光のスペクトルを測定値として用いることもできる。もしくは、投光手段14a〜14hから受光手段16に直接検査光を照射した際に受光手段16によって受光した直接光のスペクトルと、透過光のスペクトルとに基づき算出される吸光度スペクトルを測定値としてもよいし、この吸光度スペクトルを波長に対して2次微分したデータを測定値としてもよい。すなわち、青果物Tの検査内容に応じて、測定値を適宜変換させることで、検査内容に対して最適な測定値を用いることが好ましい。 The arithmetic processing means 18 may perform the inspection using the measured value acquired by the light receiving means 16, that is, the light amount value of the transmitted light as it is, and for example, a light receiving means 16 having a spectral function may be used. If so, the spectrum of transmitted light can also be used as the measured value. Alternatively, the absorbance spectrum calculated based on the spectrum of the direct light received by the light receiving means 16 when the light receiving means 16 is directly irradiated with the inspection light from the light projecting means 14a to 14h and the spectrum of the transmitted light can be used as the measured value. Alternatively, the measured value may be data obtained by second-order differentiation of this absorbance spectrum with respect to the wavelength. That is, it is preferable to use the optimum measured value for the inspection content by appropriately converting the measured value according to the inspection content of the fruit and vegetable T.

このように構成される本実施形態の内部品質検査装置10では、演算処理手段18において、測定値に基づき、例えば、青果物Tの糖度、酸度、熟度、内部障害などの内部品質を検査することができる。コンピュータにより扱いやすくするため、内部品質は数値化し、品質値とすることが好ましい。また、品質値として異常の有無を検査する場合には、ブール型(Boolean datatype)のデータとすることもできる。なお、このような内部品質の検査方法としては、従来公知の方法を用いることができる。 In the internal quality inspection device 10 of the present embodiment configured as described above, the arithmetic processing means 18 inspects the internal quality of fruits and vegetables T, for example, sugar content, acidity, ripeness, internal damage, etc., based on the measured values. Can be done. In order to make it easier to handle by a computer, it is preferable to quantify the internal quality and use it as a quality value. In addition, when inspecting the presence or absence of abnormality as a quality value, Boolean datatype data can be used. As such an internal quality inspection method, a conventionally known method can be used.

なお具体的には、本実施形態の内部品質検査装置10では、以下のようにして、青果物Tの内部品質の検査を行うことができる。
搬送手段12の穴あきトレー12aに青果物Tを載置した状態で、所定方向に一定速度で搬送する。図4(a)に示すように、青果物Tが検査光の照射領域に到達すると、投光手段14a〜14hから青果物Tに対して検査光を照射するとともに、受光手段16によって青果物Tを透過した検査光(透過光)を受光する。
Specifically, the internal quality inspection device 10 of the present embodiment can inspect the internal quality of fruits and vegetables T as follows.
With the fruits and vegetables T placed on the perforated tray 12a of the transport means 12, the fruits and vegetables T are transported in a predetermined direction at a constant speed. As shown in FIG. 4A, when the fruits and vegetables T reached the irradiation area of the inspection light, the fruits and vegetables T were irradiated with the inspection light from the light projecting means 14a to 14h, and the fruits and vegetables T were transmitted by the light receiving means 16. Receives inspection light (transmitted light).

演算処理手段18は、受光手段16によって取得された測定値に基づき、青果物Tにおける検査光の照射領域(青果物Tの第1領域M1)の内部品質を検査する。 The arithmetic processing means 18 inspects the internal quality of the irradiation region of the inspection light (the first region M 1 of the fruits and vegetables T) in the fruits and vegetables T based on the measured values acquired by the light receiving means 16.

搬送手段12により青果物Tを搬送するに伴い、図4(b)、(c)に示すように、青果物Tにおける検査光の照射領域が、第M領域MM、第N領域MNと移動する(M,Nは自然数であり、M<N。)。受光手段16は、このように検査光の照射領域を移動させながら、照射領域における測定値を順次取得し、これに基づき、演算処理手段18は、各照射領域における内部品質を順次検査する。青果物Tに対する照射領域をいくつに分割するかは、青果物Tの種類や大きさに応じて適宜決定することができる。 As the fruits and vegetables T are transported by the transport means 12, as shown in FIGS. 4 (b) and 4 (c), the irradiation region of the inspection light in the fruits and vegetables T moves to the M region MM and the N region MN. (M and N are natural numbers, and M <N.). The light receiving means 16 sequentially acquires the measured values in the irradiation region while moving the irradiation region of the inspection light in this way, and based on this, the arithmetic processing means 18 sequentially inspects the internal quality in each irradiation region. The number of areas to be irradiated with the fruits and vegetables T can be appropriately determined according to the type and size of the fruits and vegetables T.

このように、青果物Tの略半周に亘って検査光を照射するとともに、青果物Tを複数の領域に分割して、内部品質を検査することによって、青果物Tにおいて検査光が透過しない箇所が生じることなく、また、青果物Tの分割された領域毎に内部品質を検査しているため、例えば、パイナップルに生じる黒目病など、青果物内部において、不特定箇所に生じる内部障害であっても、精度良く発見することができる。 In this way, by irradiating the inspection light over approximately half the circumference of the fruit and vegetable T, dividing the fruit and vegetable T into a plurality of regions, and inspecting the internal quality, there are places in the fruit and vegetable T where the inspection light does not pass. In addition, since the internal quality is inspected for each divided area of the fruit and vegetable T, even if it is an internal disorder that occurs in an unspecified place inside the fruit or vegetable, such as black eye disease that occurs in pineapple, it can be detected accurately. can do.

なお、青果物Tに対する検査光の照射領域は、例えば、搬送手段12の穴あきトレー12aの位置を、リニアエンコーダーなどを用いて検出することによって把握するように構成することができる。 The irradiation region of the inspection light for the fruits and vegetables T can be configured to be grasped by detecting, for example, the position of the perforated tray 12a of the transport means 12 using a linear encoder or the like.

図1〜4に示す内部品質検査装置10では、穴あきトレー12aに載置した青果物Tを搬送手段12によって搬送することで、青果物Tに対する検査光の照射領域を移動させていたが、本実施形態の内部品質検査装置10では、青果物Tは載置台52に載置した状態で、投光手段14a〜14hを移動機構54によって移動させることで、青果物Tに対する検査光の照射領域を移動させる。 In the internal quality inspection apparatus 10 shown in FIGS. 1 to 4, the fruit and vegetable T placed on the perforated tray 12a is transported by the transport means 12, and the irradiation region of the inspection light on the fruit and vegetable T is moved. In the internal quality inspection device 10 of the form, the fruit and vegetable T is placed on the mounting table 52, and the light projecting means 14a to 14h are moved by the moving mechanism 54 to move the irradiation region of the inspection light on the fruit and vegetable T.

このように構成した場合であっても、図1〜4に示す内部品質検査装置10と同様に内部品質の検査を行うことが可能となる。
すなわち、青果物Tと投光手段14a〜14hとを相対的に移動させることで、青果物Tに対する検査光の照射領域を移動させ、青果物Tを複数の領域に分割して、内部品質を検査することができる。
Even with such a configuration, it is possible to inspect the internal quality in the same manner as the internal quality inspection apparatus 10 shown in FIGS. 1 to 4.
That is, by relatively moving the fruits and vegetables T and the light projecting means 14a to 14h, the irradiation area of the inspection light for the fruits and vegetables T is moved, the fruits and vegetables T is divided into a plurality of areas, and the internal quality is inspected. Can be done.
