Description

本発明は、果実の果柄を切断する果実の果柄切断機および果柄切断方法、並びに果柄切断装置に関する。   The present invention relates to a fruit pattern cutting machine, a fruit pattern cutting method, and a fruit pattern cutting device for cutting a fruit pattern.

従来、イチゴ、トマト、きゅうり等のように、果柄を介して実が吊下される果実の収穫においては、果実を傷めないために人手による収穫が主であった。しかし近年、農業における労働力不足に加えて、果実の収穫は過酷な作業環境下で長時間労働を強いられることから、作業効率の向上、労働負荷の軽減を目的として収穫作業の機械化に対する要望が高まってきている。   Conventionally, in harvesting fruits such as strawberries, tomatoes, cucumbers, etc., where fruits are suspended through a fruit handle, the harvesting has been mainly performed manually so as not to damage the fruits. However, in recent years, in addition to the labor shortage in agriculture, fruit harvesting has been forced to work for a long time in a harsh working environment, so there is a demand for mechanization of harvesting work for the purpose of improving work efficiency and reducing workload. It is increasing.

このような要望を受けて、画像処理技術やマニピュレーション制御技術などといったロボット技術を活用した果実収穫装置が開発、実用化されている。具体的に果実収穫装置は、主に、果実の位置を検出する画像処理部と、画像処理部で検出された位置に合わせてアームにより把持ハンドを接近させ、把持ハンドで果実を把持、収穫して搬送トレイへ置くマニピュレータとで構成されている。   In response to such demands, fruit harvesting devices utilizing robot technology such as image processing technology and manipulation control technology have been developed and put into practical use. Specifically, the fruit harvesting apparatus mainly includes an image processing unit that detects the position of the fruit, and a gripping hand that approaches the position detected by the image processing unit, and grips and harvests the fruit with the gripping hand. And a manipulator placed on the transfer tray.

果実収穫装置として、例えば特許文献１（特開２００８−２０６４３８号公報）には、果実群の下方と正面から果実をそれぞれ撮像する撮像装置を備え、これらの撮像装置で撮像した画像から果実の三次元位置を特定し、この位置に合わせてマニピュレータを作動させて果実を収穫する構成が開示されている。さらにこのマニピュレータは、果実群に向かって左右に並列配置されており、果実との距離に合わせて水平旋回して果実を把持するようになっている。   As a fruit harvesting device, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2008-206438) includes an imaging device that images the fruit from below and in front of the fruit group, and from the images captured by these imaging devices, the third order of the fruit A configuration is disclosed in which the original position is specified and the manipulator is operated in accordance with this position to harvest the fruit. Furthermore, this manipulator is arranged in parallel on the left and right sides toward the fruit group, and is adapted to horizontally hold the fruit in accordance with the distance from the fruit.

こういった果実収穫装置においては、果実を切断する際に、果実の損傷を防ぐために把持ハンドで果実の直上の茎をつかみ、さらにつかんだ部分の上側で茎を切り取るようになっていた。しかし、結果として、切り取られた果実に余分な茎が残ることとなる。一般に、出荷される果実は、パック等に詰めた際に茎が他の果実に当たって果肉を傷つけないように、あるいは見栄え等の観点から余分な茎は除去されることが望ましい。そこで従来は、余分な茎、すなわち果柄を手作業で切り取っていた。   In such a fruit harvesting apparatus, when a fruit is cut, in order to prevent damage to the fruit, the stem immediately above the fruit is grasped with a gripping hand, and the stem is further cut off above the grasped part. However, as a result, extra stems remain in the cut fruit. In general, it is desirable to remove excess stems from the viewpoint of appearance or the like so that the fruits to be shipped do not damage the flesh when the stems hit other fruits when packed in a pack or the like. Therefore, conventionally, an extra stem, that is, a fruit handle was manually cut off.

このように、ロボット技術を用いて収穫作業を自動化しても、結果的に新たな手作業が増えてしまい、収穫自動化による効率向上が相殺されてしまうという問題があった。
そこで、特許文献２（特開２００８−１１８１９号公報）には、果柄が果実から露出しないように果柄を切断することができる果柄切断装置が開示されている。この装置は、空気または電気などの駆動源により駆動する駆動機構と、該駆動機構に接続された可動刃保持部および可動刃と、可動刃に対向した固定刃とを備える。そして、固定刃と可動刃の間に果柄を挿入し、駆動機構を駆動させて可動刃を固定刃方向へスライドさせて果柄を切断する。 As described above, even if the harvesting work is automated using the robot technology, there is a problem that new manual work increases as a result, and the efficiency improvement by the harvesting automation is offset.
Therefore, Patent Document 2 (Japanese Patent Laid-Open No. 2008-11819) discloses a fruit pattern cutting device that can cut a fruit pattern so that the fruit pattern is not exposed from the fruit. This apparatus includes a drive mechanism that is driven by a drive source such as air or electricity, a movable blade holding portion and a movable blade that are connected to the drive mechanism, and a fixed blade that faces the movable blade. Then, a fruit handle is inserted between the fixed blade and the movable blade, the drive mechanism is driven, and the movable blade is slid in the direction of the fixed blade to cut the fruit handle.

特開２００８−２０６４３８号公報JP 2008-206438 A 特開２００８−１１８１９号公報JP 2008-11819 A

しかしながら、特許文献２に記載される果柄切断装置は、駆動機構で可動刃を駆動させる構成となっており、駆動機構を内蔵するため装置が大型化し、また駆動機構の動力エネルギが必要となることからランニングコストが嵩むという問題があった。さらに、可動刃を保持する可動刃ガイドが果実に接触しない位置に配置される構成としており、可動刃と固定刃の間に挿入する果実の位置調整が難しく、所望の長さの果柄が残るように果柄を切断することは困難であった。   However, the pattern cutting device described in Patent Document 2 has a configuration in which the movable blade is driven by the drive mechanism, and since the drive mechanism is built in, the device becomes large and the power energy of the drive mechanism is required. Therefore, there was a problem that the running cost increased. Furthermore, the movable blade guide that holds the movable blade is arranged at a position where it does not come into contact with the fruit, and it is difficult to adjust the position of the fruit inserted between the movable blade and the fixed blade, so that a handle with a desired length remains. It was difficult to cut the fruit handle.

本発明はかかる従来技術の課題に鑑み、駆動源を必要としない簡単な構成を有し、果実を傷つけることなく確実に果柄を切断可能な果実の果柄切断機および果柄切断方法、並びに果柄切断装置を提供することを目的とする。   In view of the problems of the prior art, the present invention has a simple configuration that does not require a drive source, a fruit pattern cutting machine and a fruit pattern cutting method capable of reliably cutting a fruit pattern without damaging the fruit, and An object is to provide a fruit pattern cutting device.

上記の課題を解決するために、本発明に係る果実の果柄切断機は、果実の果柄を切断する果実の果柄切断機であって、平行な一対の支軸を中心に回動し、刃先が互いに対向して配置された一対の刃部と、前記一対の刃部の下方に配置され、前記刃先の下側可動範囲を決定する下側ストッパ部と、前記一対の刃部の上方に配置され、前記刃先の上側可動範囲を決定する上側ストッパ部とを備え、前記下側ストッパ部は、一対の刃先間の開口幅が前記果実の肩幅より小さく且つ果柄径より大きくなる位置で前記刃先を支持するように配置されており、前記下側ストッパ部により支持された前記一対の刃先間に前記果柄が挿入され、前記果柄が上方に引き上げられることにより前記果実の肩部と接触する前記一対の刃部が上方に回動して前記果柄を切断するようにしたことを特徴とする。   In order to solve the above-mentioned problems, a fruit fruit cutting machine according to the present invention is a fruit fruit cutting machine for cutting a fruit fruit pattern, which rotates around a pair of parallel spindles. A pair of blade portions whose blade edges are arranged to face each other; a lower stopper portion that is disposed below the pair of blade portions and determines a lower movable range of the blade edges; and above the pair of blade portions An upper stopper portion that determines an upper movable range of the blade edge, and the lower stopper portion is located at a position where an opening width between a pair of blade edges is smaller than a shoulder width of the fruit and larger than a fruit handle diameter. It is arranged so as to support the cutting edge, the fruit handle is inserted between the pair of cutting edges supported by the lower stopper portion, and the fruit handle is pulled upward to The pair of blade portions that come into contact with each other rotate upward to Characterized by being adapted to cross.

この果柄切断機によれば、果実の肩部で一対の刃部を押し上げ、これにより刃部を回動させて果柄を切断するようにしたので、刃部を駆動する駆動機構を設けずに済み、装置の小型化が可能で、且つ油圧や空気圧等の駆動源を不要とすることができる。ここで、果柄に近い果実の肩部は、一般に果肉の中でもっとも硬い部分であり、本構成では刃部を押し上げる力しかかからないので、果実を傷めることはない。
また、下側ストッパ部は、一対の刃先間の開口幅が果実の肩幅より小さく且つ果柄径より大きくなる位置で刃先を支持するように配置されているため、刃部の回動により果実が挟まれて果実に傷がつくことを防止できる。
さらに、上側ストッパ部により上側可動範囲を決定する構成としているため、刃部が必要以上に上方に回動することを防止できる。なお、本発明において果柄とは、果実の柄になっている部分のことをいう。また、果実の肩部とは、果実が吊下された状態で果実の鉛直方向の部位と果柄との間の部分のことをいう。 According to this fruit cutting machine, the pair of blades are pushed up by the shoulder of the fruit, and the blade part is rotated by this to cut the fruit handle, so there is no drive mechanism for driving the blade part. Thus, the apparatus can be miniaturized and a driving source such as hydraulic pressure or pneumatic pressure can be dispensed with. Here, the shoulder part of the fruit close to the fruit handle is generally the hardest part in the pulp, and in this configuration, only the force for pushing up the blade part is applied, so that the fruit is not damaged.
Further, the lower stopper portion is arranged so as to support the blade edge at a position where the opening width between the pair of blade edges is smaller than the shoulder width of the fruit and larger than the fruit handle diameter. It can prevent the fruit from being scratched.
Further, since the upper movable range is determined by the upper stopper portion, it is possible to prevent the blade portion from rotating more than necessary. In addition, in this invention, a fruit handle means the part used as the handle of a fruit. Moreover, the shoulder part of a fruit means the part between the site | part of the vertical direction of a fruit, and a fruit handle in the state where the fruit was suspended.

また、上記果柄切断機において、前記一対の刃部は、これらの刃先がそれぞれ前記支軸と同一高さのときに刃先端が互いに一致するように構成され、前記上側ストッパ部は、前記刃先が前記支軸より上方へ回動することを規制するように配置されていてもよい。   Further, in the above pattern cutting machine, the pair of blade portions are configured such that the tips of the blades coincide with each other when the blade tips are the same height as the spindle, and the upper stopper portion includes the blade tips. May be arranged so as to restrict the pivoting upward from the support shaft.

刃先端が一致する位置が支軸の高さより下側であると、下側ストッパ部で支持される刃先端の位置もより下側に移動する。そうすると、果実の肩部が刃部に接触するとき、刃先がより大きな角度をもって果実の肩部に接触することとなり、果実を傷つける可能性が出てくる。したがって、本構成のように、刃先がそれぞれ支軸と同一高さのときに刃先端が互いに一致するように構成されることにより、下側ストッパ部で支持される刃部をより水平に近い角度とすることができ、刃先で果実が傷つくことを防ぐことができる。   If the position where the blade tip coincides is below the height of the support shaft, the position of the blade tip supported by the lower stopper portion also moves downward. If it does so, when the shoulder part of a fruit contacts a blade part, a blade edge | tip will contact the shoulder part of a fruit with a larger angle, and the possibility of damaging a fruit will come out. Therefore, as in this configuration, when the blade tips are the same height as the support shaft, the blade tips are configured to coincide with each other, so that the blade portion supported by the lower stopper portion is closer to the horizontal angle. And the fruit can be prevented from being damaged by the blade edge.

また、上記果柄切断機において、前記一対の支軸にそれぞれ連結して前記一対の刃部の回動を左右対称で同期させる機構、例えばギヤ部をさらに備える構成としてもよい。
このように、ギヤ部により一対の刃部の回動を左右対称で同期させることにより、対向する刃先端を正確に一致させることができ、果柄を確実に切断することが可能となる。 The fruit pattern cutting machine may further include a mechanism that is coupled to the pair of support shafts and synchronizes the rotation of the pair of blade portions symmetrically, for example, a gear portion.
Thus, by synchronizing the rotation of the pair of blade portions symmetrically with the gear portion, the opposing blade tips can be accurately matched, and the fruit pattern can be cut reliably.

さらに、上記果柄切断機において、前記果実の種類に応じて、前記刃部の前記果実との接触部位から刃先端までの前記刃部の肉厚方向の高さを調整する調整手段をさらに備える構成としてもよい。   The fruit pattern cutting machine further includes adjusting means for adjusting a height of the blade portion in a thickness direction from a contact portion of the blade portion with the fruit to a blade tip in accordance with the type of the fruit. It is good also as a structure.

このように、刃部の果実との接触部位から刃先端までの刃部の肉厚方向の高さを調整する調整手段を備えることにより、果柄切断後の果柄の長さを自在に設定可能となる。通常、果実はその種類に応じて、出荷時に残しておくべき果柄の長さがおおよそ決まっている。したがって、上記したような調整手段を備えることにより、適切な長さの果柄を残すことができ、果実の商品価値を高くすることができる。   In this way, the length of the fruit pattern after cutting the fruit pattern can be freely set by providing an adjusting means that adjusts the height in the thickness direction of the blade part from the contact part with the fruit of the blade part to the tip of the blade. It becomes possible. Usually, depending on the type of fruit, the length of the fruit pattern to be left at the time of shipment is roughly determined. Therefore, by providing the adjusting means as described above, it is possible to leave a fruit with an appropriate length and increase the commercial value of the fruit.

本発明に係る果実の果柄切断方法は、果実の果柄を切断する果実の果柄切断方法であって、平行な一対の支軸を中心に回動する一対の刃部が用いられ、前記一対の刃部の各刃先が下側ストッパで支持された状態で、これらの刃先間の隙間に前記果柄が挿入される工程と、前記果柄が上方に引き上げられるに従って前記果実の肩部で前記刃部が押されて上方に回動し、前記果柄を切断する工程とを有することを特徴とする。   The fruit stalk cutting method according to the present invention is a fruit stalk cutting method for cutting a fruit stalk, wherein a pair of blade parts rotating around a pair of parallel spindles are used, In a state where each blade edge of the pair of blade portions is supported by a lower stopper, the step of inserting the fruit handle into the gap between these blade edges, and the shoulder portion of the fruit as the fruit handle is pulled upward And a step of cutting the fruit handle by pressing the blade portion and turning upward.

この果柄切断方法によれば、果実の肩部で一対の刃部を押し上げ、これにより刃部を回動させて果柄を切断するようにしたので、果柄の切断動作を少ない工程で行うことができ、収穫作業の時間の短縮化が図れる。また、駆動機構を用いる必要がないため、果柄切断作業の簡易化が可能となる。   According to this pattern cutting method, the pair of blades are pushed up by the shoulder of the fruit, and the blade is rotated by this to cut the pattern. Therefore, the pattern cutting operation is performed in a small number of steps. This shortens the harvesting time. In addition, since it is not necessary to use a drive mechanism, it is possible to simplify the fruit cutting operation.

また、本発明に係る果実の果柄切断装置は、果実の果柄を切断する果実の果柄切断装置であって、前記果実の果柄を把持し、前記果実ごと前記果柄を移動させる把持部と、平行な一対の支軸を中心に回動し、刃先が互いに対向して配置された一対の刃部と、前記一対の刃部の下方に配置され、前記刃先の下側可動範囲を決定する下側ストッパ部と、前記一対の刃部の上方に配置され、前記刃先の上側可動範囲を決定する上側ストッパ部とを備え、前記下側ストッパ部は、一対の刃先間の開口幅が前記果実の肩幅より小さく且つ果柄径より大きくなる位置で前記刃先を支持するように配置されており、前記下側ストッパ部により支持された前記一対の刃先間に前記把持部で把持した前記果柄を挿入し、前記把持部により前記果柄を上方に引き上げることにより前記果実の肩部と接触する前記一対の刃部が上方に回動して前記果柄を切断するようにしたことを特徴とする。   Further, the fruit pattern cutting device according to the present invention is a fruit pattern cutting device for cutting a fruit pattern, and holds the fruit pattern and moves the fruit pattern together with the fruit. And a pair of blades that rotate around a pair of parallel support shafts and the blade edges are opposed to each other, and are disposed below the pair of blade parts, and the lower movable range of the blade edges A lower stopper portion to be determined, and an upper stopper portion that is disposed above the pair of blade portions and determines an upper movable range of the blade edge, and the lower stopper portion has an opening width between the pair of blade edges. The fruit that is arranged to support the blade edge at a position that is smaller than the shoulder width of the fruit and larger than the fruit handle diameter, and is gripped by the grip portion between the pair of blade edges supported by the lower stopper portion. Insert the handle and pull the fruit handle upward by the grip Wherein the pair of blade portions in contact with the shoulder of the fruit by Rukoto is so pivoted upwardly to cut the peduncles.

この果柄切断装置によれば、果実の肩部で一対の刃部を押し上げ、これにより刃部を回動させて果柄を切断するようにしたので、刃部を駆動する駆動機構を設けずに済み、装置の小型化が可能で、且つ油圧や空気圧等の駆動源を不要とすることができる。
また、下側ストッパ部は、一対の刃先間の開口幅が果実の肩幅より小さく且つ果柄径より大きくなる位置で刃先を支持するように配置されているため、刃部の回動により果実が挟まれて果実に傷がつくことを防止できる。
さらに、上側ストッパ部により上側可動範囲を決定する構成としているため、刃部が必要以上に上方に回動することを防止できる。なお、本発明において把持部は、油圧または空気圧、あるいは電気等により駆動するように構成されていてもよい。 According to this pattern cutting device, since the pair of blades are pushed up by the shoulder of the fruit and the blade is rotated thereby to cut the pattern, no drive mechanism for driving the blade is provided. Thus, the apparatus can be miniaturized and a driving source such as hydraulic pressure or pneumatic pressure can be dispensed with.
Further, the lower stopper portion is arranged so as to support the blade edge at a position where the opening width between the pair of blade edges is smaller than the shoulder width of the fruit and larger than the fruit handle diameter. It can prevent the fruit from being scratched.
Further, since the upper movable range is determined by the upper stopper portion, it is possible to prevent the blade portion from rotating more than necessary. In the present invention, the grip portion may be configured to be driven by hydraulic pressure, pneumatic pressure, electricity, or the like.

以上記載のように本発明によれば、果実の肩部で一対の刃部を押し上げ、これにより刃部を回動させて果柄を切断するようにしたので、刃部を駆動する駆動機構を設けずに済み、装置の小型化が可能で、且つ油圧や空気圧等の駆動源を不要とすることができる。
また、下側ストッパ部は、一対の刃先間の開口幅が果実の肩幅より小さく且つ果柄径より大きくなる位置で刃先を支持するように配置されているため、刃部の回動により果実が挟まれて果実に傷がつくことを防止できる。
さらに、上側ストッパ部により上側可動範囲を決定する構成としているため、刃部が必要以上に上方に回動することを防止できる。 As described above, according to the present invention, the pair of blade portions are pushed up by the shoulder portion of the fruit, and the blade portion is thereby rotated to cut the fruit handle. It is not necessary to provide the device, the apparatus can be downsized, and a driving source such as hydraulic pressure or pneumatic pressure can be omitted.
Further, the lower stopper portion is arranged so as to support the blade edge at a position where the opening width between the pair of blade edges is smaller than the shoulder width of the fruit and larger than the fruit handle diameter. It can prevent the fruit from being scratched.
Further, since the upper movable range is determined by the upper stopper portion, it is possible to prevent the blade portion from rotating more than necessary.

However, as long as there is no specific description, the dimensions, materials, shapes, relative arrangements, and the like of the component parts described in this embodiment are not intended to limit the scope of the present invention, but are merely illustrative examples. Absent.

図１および図２を参照して、本発明の実施形態に係る果柄切断機を説明する。ここで、図１は本発明の実施形態に係る果柄切断機の一例を示す斜視図で、図２は図１に示した果柄切断機の側面図である。
本実施形態の果柄切断機１は、果実の果柄を切断するものである。なお、本実施形態の果柄切断機１が適用できる果実は、イチゴ、ぶどう、さくらんぼ、トマト、きゅうり、ピーマン等のように、果柄を介して実が茎に吊下される果実である。このとき、果実は、果物や野菜（あるいは分類方法により果菜類）を含むものである。また、果柄とは、果実の柄になっている部分のことをいう。 A fruit cutting machine according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. Here, FIG. 1 is a perspective view showing an example of a fruit cutting machine according to an embodiment of the present invention, and FIG. 2 is a side view of the fruit cutting machine shown in FIG.
The fruit pattern cutting machine 1 of this embodiment cuts the fruit pattern. In addition, the fruit which can apply the fruit cutting machine 1 of this embodiment is a fruit by which a fruit is hung on a stem through a fruit pattern like a strawberry, a grape, a cherry, a tomato, a cucumber, a bell pepper. At this time, the fruits include fruits and vegetables (or fruits and vegetables depending on the classification method). Moreover, a fruit pattern means the part used as the pattern of a fruit.

この果柄切断機１は、一対の刃部２と、刃部２の下方に配置される下側ストッパ部３と、刃部２の上方に配置される上側ストッパ部４とを備える。
一対の刃部２は、フレーム５に取り付けられた一対の支軸２０を中心に、それぞれ自在に回動するようになっている。これらの刃部２の刃先２２は、互いに対向して配置されている。そして、支軸２０に対して刃先２２が所定の角度に位置するときに、一対の刃先端２２ａが互いに一致するようになっている。好適には、一対の刃部２は、これらの刃先２２がそれぞれ支軸２０と同一高さのとき、すなわち刃部２の刃面２１が水平になったときに、刃先端２２ａが互いに一致するように構成されるとよい。ここで、「刃先端２２ａが一致する」とは、２つの刃先端２２ａが接する状態、および果柄径より小さい間隙を存して非接触で近接する状態を含む。また、刃部２は、板状で且つ刃先端２２ａが直線状である直線刃を用いることが好ましい。ここで、支軸２０には、例えばヒンジ等が用いられる。 The fruit pattern cutting machine 1 includes a pair of blade portions 2, a lower stopper portion 3 disposed below the blade portion 2, and an upper stopper portion 4 disposed above the blade portion 2.
The pair of blade portions 2 are configured to freely rotate around a pair of support shafts 20 attached to the frame 5. The blade edges 22 of these blade portions 2 are arranged to face each other. When the blade edge 22 is positioned at a predetermined angle with respect to the support shaft 20, the pair of blade tips 22a are configured to coincide with each other. Preferably, the pair of blade portions 2 have their blade tips 22a coincide with each other when the blade edges 22 are at the same height as the support shaft 20, that is, when the blade surface 21 of the blade portion 2 is horizontal. It is good to be configured as follows. Here, “the blade tips 22a match” includes a state where the two blade tips 22a are in contact with each other and a state where the blade tips 22a are close to each other with a gap smaller than the fruit handle diameter. Moreover, it is preferable that the blade part 2 uses the straight blade which is plate shape and the blade front-end | tip 22a is linear. Here, for example, a hinge or the like is used for the support shaft 20.

通常、一対の刃部２は、初期状態において重力により刃先２２が下方に位置して、後述する下側ストッパ部３で支持されるようになっているが、確実に刃先２２が下方に位置するように、バネ部材７等の弾性部材を設けてもよい。例えば、バネ部材７は刃部２の下面とフレーム５との間に張架され、刃先２２に対して下向きの力を強制的に加えるようになっている。   Usually, the pair of blade parts 2 are configured such that the blade edge 22 is positioned downward by gravity in the initial state and is supported by the lower stopper 3 described later, but the blade edge 22 is reliably positioned below. As described above, an elastic member such as the spring member 7 may be provided. For example, the spring member 7 is stretched between the lower surface of the blade portion 2 and the frame 5, and a downward force is forcibly applied to the blade edge 22.

下側ストッパ部３は、刃先２２の下側可動範囲を決定するものである。具体的には、下側ストッパ部３は、一対の刃先２２間の開口幅が果実の肩幅より小さく且つ果柄径より大きくなる位置で刃先２２を支持するように、一対の刃部２の下方にそれぞれ配置されている。なお、果実の肩部とは、果実が吊下された状態で果実の鉛直方向の部位と果柄との間の部分のことをいう。
上側ストッパ部４は、刃先２２の上側可動範囲を決定するものであり、刃先２２が支軸２０より上方、すなわち水平方向より上方へ回動することを規制するように配置する。この上側ストッパ部４は、一対の刃部２のそれぞれに個別に設けてもよいし、一対の刃部２の両方を規制するように一つだけ設けてもよい。 The lower stopper portion 3 determines the lower movable range of the blade edge 22. Specifically, the lower stopper portion 3 is positioned below the pair of blade portions 2 so as to support the blade edge 22 at a position where the opening width between the pair of blade edges 22 is smaller than the shoulder width of the fruit and larger than the fruit handle diameter. Respectively. In addition, the shoulder part of a fruit means the part between the site | part of the vertical direction of a fruit, and a fruit handle in the state where the fruit was suspended.
The upper stopper portion 4 determines the upper movable range of the blade edge 22 and is disposed so as to restrict the blade edge 22 from rotating upward from the support shaft 20, that is, from the horizontal direction. This upper stopper portion 4 may be provided individually for each of the pair of blade portions 2, or only one may be provided so as to regulate both of the pair of blade portions 2.

また、本発明の実施形態に係る果柄切断装置は、上記した果実切断機１に加えて、果実の果柄を把持し、果実ごと果柄を移動させる把持部１０（図３参照）をさらに備えている。把持部１０は、果実の果柄を掴んで一対の刃先２２間に果柄を挿入する位置に移動し、その後果柄を上方に引き上げる動作を行う。この把持部１０は、油圧または空気圧、あるいは電気等を用いた駆動機構により上記動作を実行するようにしてもよい。   Moreover, in addition to the fruit cutting machine 1 described above, the fruit cutting apparatus according to the embodiment of the present invention further includes a gripping unit 10 (see FIG. 3) that grips the fruit fruit and moves the fruit together with the fruit. I have. The gripping part 10 grasps the fruit pattern and moves to a position where the fruit pattern is inserted between the pair of blades 22, and then pulls the fruit pattern upward. The gripping unit 10 may perform the above operation by a drive mechanism using hydraulic pressure, pneumatic pressure, electricity, or the like.

次に、図３を用いて、本実施形態に係る果柄切断機の作用を、果柄切断方法とともに説明する。
果柄切断機１の最初の状態は、重力により刃部２の刃先２２が下方に位置し、下側ストッパ部３により支持されている。
図３（Ａ）に示すように果柄挿入工程において、把持部１０は、果柄３２を把持した状態で刃部２まで移動し、果柄３２を刃先２２間に挿入する。
次いで、図３（Ｂ）に示すように果柄切断工程において、把持部１０は果柄３２を上方に引き上げる。これにより果実３０の肩部３３で刃部２が押されて上方に回動する。一対の刃部２が同時に回動し、これに伴い一対の刃先端２２ａ間の開口幅が減少し、水平位置に近くなると刃先端２２ａが果柄３２に切り込み、刃部２の刃面２１がほぼ水平になる位置で果実３０を切断する。 Next, the operation of the fruit cutting machine according to the present embodiment will be described together with the fruit cutting method using FIG.
In the initial state of the fruit pattern cutting machine 1, the cutting edge 22 of the blade portion 2 is positioned below due to gravity and is supported by the lower stopper portion 3.
As shown in FIG. 3A, in the fruit pattern insertion step, the gripping part 10 moves to the blade part 2 while gripping the fruit pattern 32 and inserts the fruit pattern 32 between the blade edges 22.
Next, as shown in FIG. 3B, in the fruit pattern cutting step, the gripping part 10 pulls up the fruit pattern 32 upward. Thereby, the blade part 2 is pushed by the shoulder part 33 of the fruit 30, and rotates upwards. The pair of blade portions 2 rotate simultaneously, and accordingly, the opening width between the pair of blade tips 22a decreases, and when approaching the horizontal position, the blade tips 22a cut into the fruit handle 32, and the blade surface 21 of the blade portion 2 Cut the fruit 30 at a position that is approximately horizontal.

そして、図３（Ｃ）に示すように、果実３０の果肉部分３１から果柄３２を切り離す。切り離された果実３０を受ける収納ケース内には、緩衝部材を敷設しておくことが好ましい。
なお、果柄切断機１を長時間稼働し、刃先２２がなまってしまい果柄３２を完全に切断できなかった場合、最終的には果柄３２を引き切ることになるが、その際に引く力が加わるのは一対の刃部２に挟まれた果柄３２の部分であり、果肉３１には無理な力が働かないので果肉３１を傷めることはない。 And as shown in FIG.3 (C), the fruit handle 32 is cut | disconnected from the pulp part 31 of the fruit 30. FIG. It is preferable to lay a buffer member in the storage case that receives the separated fruit 30.
In addition, when the fruit pattern cutting machine 1 is operated for a long time and the cutting edge 22 is distorted and the fruit pattern 32 cannot be completely cut, the fruit pattern 32 is finally pulled, but at that time The force is applied to the portion of the fruit handle 32 sandwiched between the pair of blade portions 2, and no excessive force is applied to the pulp 31, so that the pulp 31 is not damaged.

上記した果柄切断機１は、果実３０を主茎から自動で収穫する果実収穫装置とともに設置し、これらの装置間で把持部１０を共通化してもよい。具体的には、果実収穫装置と収納ケースとの間に果柄切断機１を設置する。そして、果実収穫装置にて果実３０を収穫した後、把持部１０で果柄３２をつかんだ状態のまま果柄切断機１に移動し、果柄切断機１で果柄３２を切断して収納ケースに果実を収納する。このような一連の作業の流れとすることで、果柄切断機１を設置しない場合と比べても、収穫から収納までの動作時間にほとんど影響を与えずに収穫作業を行うことが可能となる。   The fruit pattern cutting machine 1 described above may be installed together with a fruit harvesting device that automatically harvests the fruit 30 from the main stem, and the gripping unit 10 may be shared between these devices. Specifically, the fruit pattern cutting machine 1 is installed between the fruit harvesting device and the storage case. And after harvesting the fruit 30 with the fruit harvesting apparatus, it moves to the fruit pattern cutting machine 1 while holding the fruit pattern 32 with the gripping part 10, and cuts and stores the fruit pattern 32 with the fruit pattern cutting machine 1. Store the fruit in the case. By adopting such a series of work flows, it is possible to carry out the harvesting work with almost no influence on the operation time from harvesting to storage compared to the case where the fruit pattern cutting machine 1 is not installed. .

本実施形態の果柄切断機１によれば、果実３０の肩部３３で一対の刃部２を押し上げ、これにより刃部２を回動させて果柄３２を切断するようにしたので、刃部２を駆動する駆動機構を設けずに済み、装置の小型化が可能で、且つ油圧や空気圧等の駆動源を不要とすることができる。なお、果柄３２に近い果実３０の肩部３３は、一般に果肉３１の中でもっとも硬い部分であり、本構成では刃部２を押し上げる力しかかからないので、果実３０を傷めることはない。
また、下側ストッパ部３は、一対の刃先２２間の開口幅が果実３０の肩幅３３より小さく且つ果柄径より大きくなる位置で刃先２２を支持するように配置されているため、刃部２の回動により果実３０が挟まれて果肉３１に傷がつくことを防止できる。
さらに、上側ストッパ部４により上側可動範囲を決定する構成としているため、刃部２が必要以上に上方に回動することを防止できる。 According to the fruit pattern cutting machine 1 of the present embodiment, the pair of blade parts 2 are pushed up by the shoulder part 33 of the fruit 30, and the blade part 2 is thereby rotated to cut the fruit pattern 32. It is not necessary to provide a drive mechanism for driving the unit 2, the apparatus can be downsized, and a drive source such as hydraulic pressure or air pressure can be dispensed with. Note that the shoulder 33 of the fruit 30 close to the fruit handle 32 is generally the hardest part of the pulp 31, and in this configuration, only the force that pushes up the blade part 2 is applied, so the fruit 30 is not damaged.
Further, the lower stopper portion 3 is disposed so as to support the blade edge 22 at a position where the opening width between the pair of blade edges 22 is smaller than the shoulder width 33 of the fruit 30 and larger than the fruit handle diameter. It is possible to prevent the fruit 30 from being pinched by the rotation of and the flesh 31 from being damaged.
Furthermore, since it is set as the structure which determines an upper side movable range with the upper side stopper part 4, it can prevent that the blade part 2 rotates upwards more than necessary.

さらに、上記果柄切断機１において、一対の刃部２は、これらの刃先２２がそれぞれ支軸２０と同一高さのときに刃先端２２ａが互いに一致するように構成され、上側ストッパ部４は、刃先２２が支軸２０より上方へ回動することを規制するように配置されていてもよい。
刃先端２２ａが一致する位置が支軸２０の高さより下側であると、下側ストッパ部３で支持される刃先端２２ａの位置もより下側に移動する。そうすると、果実３０の肩部３３が刃部２に接触するとき、刃先２２がより大きな角度をもって果実３０の肩部３３に接触することとなり、果肉３１を傷つける可能性が出てくる。したがって、本構成のように、刃先２２がそれぞれ支軸２０と同一高さのときに刃先端２２ａが互いに一致するように構成されることにより、下側ストッパ部３で支持される刃部２をより水平に近い角度とすることができ、刃先２２で果肉３１が傷つくことを防ぐことができる。 Further, in the above pattern cutting machine 1, the pair of blade portions 2 are configured such that the blade tips 22a coincide with each other when the blade edges 22 are at the same height as the support shaft 20, respectively. The blade edge 22 may be disposed so as to be restricted from rotating upward from the support shaft 20.
If the position where the blade tip 22a coincides is below the height of the support shaft 20, the position of the blade tip 22a supported by the lower stopper portion 3 also moves downward. If it does so, when the shoulder part 33 of the fruit 30 will contact the blade part 2, the blade edge | tip 22 will contact the shoulder part 33 of the fruit 30 with a larger angle, and the possibility of damaging the pulp 31 will come out. Therefore, as in the present configuration, the blade tip 2 supported by the lower stopper portion 3 is configured by the blade tips 22a being configured to coincide with each other when the blade edges 22 are at the same height as the support shaft 20, respectively. It is possible to make the angle closer to horizontal, and it is possible to prevent the pulp 31 from being damaged by the blade edge 22.

ここで、図４および図５を参照して、本発明の実施形態に係る果柄切断機の変形例について説明する。   Here, with reference to FIG. 4 and FIG. 5, the modification of the fruit pattern cutting machine which concerns on embodiment of this invention is demonstrated.

図４に示す果柄切断機１は、果柄切断後に果実３０に残される果柄３２の長さを調整可能な調整手段を備えた構成となっている。この調整手段は、刃部２の果実３０との接触部位から刃先端２２ａまでの刃部２の肉厚方向の高さを調整するものである。
通常、果実３０はその種類に応じて、出荷時に残しておくべき果柄３２の長さがおおよそ決まっている。そこで、以下に示す調整手段を備えることによって、適切な長さの果柄３２を残すことができ、果実３０の商品価値を高くすることができる。
ここで、上記した図１乃至図３においては、刃先２２の切削面である傾斜面を果実３０と接しない方向（上側）に設置しているため、茎の根元で果柄３２を切断することができ、果柄３２はほとんど果実３０に残らない。 The fruit pattern cutting machine 1 shown in FIG. 4 is configured to include an adjusting means capable of adjusting the length of the fruit pattern 32 left on the fruit 30 after the fruit pattern is cut. This adjustment means adjusts the height in the thickness direction of the blade portion 2 from the contact portion of the blade portion 2 with the fruit 30 to the blade tip 22a.
Usually, the length of the fruit handle 32 to be left at the time of shipment is roughly determined according to the type of the fruit 30. Therefore, by providing the adjusting means shown below, it is possible to leave the fruit handle 32 of an appropriate length and increase the commercial value of the fruit 30.
Here, in FIG. 1 thru | or FIG. 3 mentioned above, since the inclined surface which is the cutting surface of the blade edge | tip 22 is installed in the direction (upper side) which does not contact with the fruit 30, cutting the fruit handle 32 at the root of a stem. The fruit pattern 32 hardly remains on the fruit 30.

図４（Ａ）に示す刃部２は、刃先２２の切削面である傾斜面２２ｂを果実３０と接する方向（下側）に設置している。なお、この傾斜面２２ｂは平面状に形成されている。
これにより果実３０に少しの果柄３２を残すことができる。
図４（Ｂ）に示す刃部２は、図４（Ａ）と同様に、刃先２２の切削面を果実３０と接する方向に設置している。さらにこの切削面を、果実３０の表面に沿って湾曲させた湾曲面２２ｃとしている。これにより果実３０と刃部２の接触面積を増大し、果実３０の肩部３３に加えられる力を分散することができる。 The blade portion 2 shown in FIG. 4A has an inclined surface 22b, which is a cutting surface of the blade edge 22, installed in a direction (lower side) in contact with the fruit 30. The inclined surface 22b is formed in a flat shape.
Thereby, a little fruit pattern 32 can be left on the fruit 30.
The blade portion 2 shown in FIG. 4B is installed in a direction in which the cutting surface of the blade edge 22 is in contact with the fruit 30 as in FIG. Further, the cutting surface is a curved surface 22 c that is curved along the surface of the fruit 30. Thereby, the contact area of the fruit 30 and the blade part 2 can be increased, and the force applied to the shoulder part 33 of the fruit 30 can be disperse | distributed.

図４（Ｃ）に示す刃部２は、刃部２の肉厚を厚くし、刃先２２に段差部２２ｄを設けている。そして、段差部２２ｄの上部に刃先端２２ａを形成し、段差部２２ｄの最下面に果実３０の肩部３３が接触するようになっている。この段差部２２ｄの高さＤを調整することにより、果実３０に残す果柄３２の長さを調整可能となっている。
図４（Ｄ）に示す刃部２は、刃部２の下面に着脱自在な調整部材２２ｅを備えた構成となっている。調整部材２２ｅを取り付けた刃部２において、調整部材２２ｅの下面が果実３０の肩部３３に接触するようになっている。このように、必要に応じて調整手段２２ｅを取り付けることにより、果実３０に残す果柄３２の長さを調整可能となっている。なお、調整部材２２ｅは高さが異なるものを複数用意しておくことで、複数段階の果柄長さ調整が可能となる。 In the blade part 2 shown in FIG. 4C, the blade part 2 is thickened and a step part 22 d is provided on the blade edge 22. And the blade tip 22a is formed in the upper part of the level | step-difference part 22d, and the shoulder part 33 of the fruit 30 contacts the lowermost surface of the level | step-difference part 22d. By adjusting the height D of the stepped portion 22d, the length of the fruit pattern 32 left on the fruit 30 can be adjusted.
The blade portion 2 shown in FIG. 4 (D) has a configuration in which a detachable adjustment member 22 e is provided on the lower surface of the blade portion 2. In the blade portion 2 to which the adjusting member 22e is attached, the lower surface of the adjusting member 22e is in contact with the shoulder portion 33 of the fruit 30. Thus, the length of the fruit pattern 32 left on the fruit 30 can be adjusted by attaching the adjusting means 22e as necessary. In addition, by preparing a plurality of adjusting members 22e having different heights, it is possible to adjust the pattern length in a plurality of stages.

図５に示す果柄切断機１は、上記した構成に加えて、一対の刃部２の回動を左右対称で同期させるギヤ部４０を備えた構成となっている。ギヤ部４０は、端部ギヤ４１と中間ギヤと４２を有する。端部ギヤ４１は、一対の支軸２０にそれぞれ連結して該支軸２０と同時に回転する。この２つの端部ギヤ４１間には、偶数個の中間ギヤ４２が設けられている。端部ギヤ４１と中間ギヤ４２とは互いに噛み合うように配置され、これにより一対の刃部２の回動を左右対称で同期させるようになっている。
また、中間ギヤ４２を設けない構成としてもよく、この場合、端部ギヤ４１同士を互いに噛み合わせて左右対称に同期させるようにする。
このように、ギヤ部４０により一対の刃部２の回動を左右対称で同期させることにより、対向する刃先端２２ａを正確に一致させることができ、果柄３２を確実に切断することが可能となる。 The fruit pattern cutting machine 1 shown in FIG. 5 has a configuration including a gear portion 40 that synchronizes the rotation of the pair of blade portions 2 symmetrically in addition to the above-described configuration. The gear unit 40 includes an end gear 41 and an intermediate gear 42. The end gear 41 is connected to the pair of support shafts 20 and rotates simultaneously with the support shafts 20. An even number of intermediate gears 42 are provided between the two end gears 41. The end gear 41 and the intermediate gear 42 are arranged so as to mesh with each other, thereby synchronizing the rotation of the pair of blade portions 2 symmetrically.
Further, the intermediate gear 42 may be omitted. In this case, the end gears 41 are meshed with each other so as to be synchronized symmetrically.
Thus, by synchronizing the rotation of the pair of blade parts 2 symmetrically by the gear part 40, the opposing blade tips 22a can be accurately matched, and the fruit handle 32 can be cut reliably. It becomes.
