Description

本願発明は、例えば柑橘類、イチゴ、桃、梨、リンゴ、メロンといった農産物を選別仕分けする選別装置に用いられる受け皿に関するものである。   The present invention relates to a saucer used in a sorting device for sorting and sorting agricultural products such as citrus fruits, strawberries, peaches, pears, apples and melons.

従来、農産物の内部品質を非破壊で計測し検査するにおいて、農産物に光を照射し農産物を透過した透過光を検出及び解析するものがよく知られている（例えば特許文献１等参照）。農産物載置用の受け皿としては一般にフリートレイ式のものが採用される。この場合、上向きに開口した受け皿の側周壁には光通過用の切り欠き部を形成している。   Conventionally, in measuring and inspecting the internal quality of agricultural products in a non-destructive manner, it is well known to detect and analyze transmitted light that has been irradiated with light and transmitted through the agricultural product (see, for example, Patent Document 1). In general, a free tray type tray is adopted as a tray for placing agricultural products. In this case, a notch for passing light is formed on the side peripheral wall of the tray that opens upward.

また、この種の受け皿の下面側には、農産物の内部品質の検査の際に受け皿を所定姿勢に揃える（受け皿の向きを一定に揃える）ための凹み部を形成することもある。例えば特許文献２の構成では、搬送コンベヤ上の受け皿を回転ベルトとガイド部材とで挟み、回転ベルトで受け皿を水平回転させながら、受け皿の下面に形成した凹み部を搬送コンベヤの上面に設けた凸条部に嵌め合わせることによって、受け皿の向きを揃えている。   In addition, a concave portion may be formed on the lower surface side of this type of saucer for aligning the saucer in a predetermined posture (the orientation of the saucer is kept constant) during the inspection of the internal quality of agricultural products. For example, in the configuration of Patent Document 2, a concave portion formed on the lower surface of the tray is provided on the upper surface of the conveyor while the tray on the conveyor is sandwiched between the rotating belt and the guide member and the tray is horizontally rotated by the rotating belt. The direction of the saucer is aligned by fitting the strip.

以下に、本願発明を具体化した実施形態を図面に基づいて説明する。なお、本願において「農産物」とは、本願発明の受け皿に載置可能なあらゆる果実及び野菜を含む概念であり、例えばイチゴやミカン等の小型のもの、桃、梨又はリンゴ等の中型のもの、メロンやスイカといった大型のものが挙げられる。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, in this application, "agricultural products" are concepts including all fruits and vegetables that can be placed on the saucer of the present invention, for example, small items such as strawberries and mandarin oranges, medium items such as peaches, pears or apples, There are large melons and watermelons.

まず、図１〜図８及び図１３〜図１８を参照しながら、農産物Ａを選別仕分けする選別装置に用いられる受け皿１１の構造について説明する。実施形態の受け皿１１は、側周壁１４と底壁１５とを有して上向きに開口した受け皿本体１２と、受け皿本体１２における底壁１５の下面側に取り付く台座体１３とを備えている。受け皿１１全体としては、上面側が下向きに凹んだ有底筒形状になっている。   First, with reference to FIGS. 1 to 8 and FIGS. 13 to 18, the structure of the tray 11 used in the sorting device that sorts and sorts the produce A will be described. The saucer 11 according to the embodiment includes a saucer body 12 that has a side peripheral wall 14 and a bottom wall 15 and opens upward, and a pedestal body 13 that is attached to the lower surface side of the bottom wall 15 of the saucer body 12. As a whole, the tray 11 has a bottomed cylindrical shape whose upper surface is recessed downward.

受け皿本体１２と台座体１３とは合成樹脂材製の射出成形品である。受け皿本体１２は上向きに開口した円筒状に構成し、台座体１３は中実の円盤状に構成している。受け皿本体１２における底壁１５の中央部には、受け皿本体１２内に収容される農産物Ａの外径より小さい穴径で且つ上下方向に貫通する本体貫通穴１６を形成している。受け皿本体１２の側周壁１４には切り欠き部１７を形成している。   The saucer body 12 and the pedestal 13 are injection molded products made of a synthetic resin material. The saucer body 12 is configured in a cylindrical shape that opens upward, and the pedestal 13 is configured in a solid disk shape. In the central portion of the bottom wall 15 in the saucer body 12, a body through-hole 16 is formed that has a hole diameter smaller than the outer diameter of the produce A accommodated in the saucer body 12 and penetrates in the vertical direction. A cutout portion 17 is formed in the side peripheral wall 14 of the tray body 12.

台座体１３の直径は、受け皿本体１２のそれとほぼ同程度に設定している。台座体１３の中央部には、受け皿本体１２の本体貫通穴１６に連通して上下方向に貫通する台座貫通穴１８を形成している。受け皿本体１２の底壁１５の下面側に台座体１３を取り付けた状態では、受け皿本体１２の本体貫通穴１６と台座体１３の台座貫通穴１８とが同心状に上下に並んで連通する。台座体１３の外周下部には、円盤の外周角部を切り落として断面逆Ｌ字状に凹ませたような形態の凹み部１９を形成している。詳細は後述するが、台座体１３の凹み部１９は、搬送路としての整列コンベヤ３３上での受け皿１１の搬送姿勢を規定するためのものである。   The diameter of the pedestal 13 is set to be approximately the same as that of the tray body 12. A pedestal through hole 18 communicating with the main body through hole 16 of the tray main body 12 and penetrating in the vertical direction is formed at the center of the base body 13. In a state where the pedestal 13 is attached to the lower surface side of the bottom wall 15 of the saucer body 12, the body through-hole 16 of the saucer body 12 and the pedestal through-hole 18 of the pedestal 13 communicate with each other side by side in a concentric manner. A dent 19 is formed in the lower part of the outer periphery of the pedestal 13 so that the outer peripheral corner of the disk is cut off and recessed into an inverted L-shaped cross section. Although the details will be described later, the recessed portion 19 of the pedestal 13 is for defining the conveying posture of the tray 11 on the alignment conveyor 33 as a conveying path.

受け皿本体１２と台座体１３とには、互いの取り付け位相が変更可能なように両者１２，１３を連結する連結部２０を設けている。この場合、受け皿本体１２の下面（底壁１５の下面）と台座体１３の上面とのうちいずれか一方に、周方向に沿った等間隔に並ぶ複数の嵌合凹所２１を形成し、残る他方に、各嵌合凹所２１に嵌まる嵌合突起２２を形成している。実施形態では、受け皿本体１２の下面（底壁１５の下面）に嵌合凹所２１群を形成している。台座体１３の上面に嵌合突起２２群を形成している。受け皿本体１２の底壁１５の下面には、底面視で本体貫通穴１６を中心として１２０°間隔で並ぶ３つの嵌合凹所２１を形成している。台座体の上面には、平面視で台座貫通穴１８を中心として１２０°間隔で並ぶ３つの嵌合突起２２を形成している。嵌合凹所２１群と嵌合突起２２群との組合せが連結部２０を構成している。   The saucer body 12 and the pedestal body 13 are provided with a connecting portion 20 that connects the both 12 and 13 so that the mounting phase of each can be changed. In this case, a plurality of fitting recesses 21 arranged at equal intervals along the circumferential direction are formed on any one of the lower surface of the tray body 12 (the lower surface of the bottom wall 15) and the upper surface of the pedestal body 13. On the other hand, fitting protrusions 22 that fit into the respective fitting recesses 21 are formed. In the embodiment, the fitting recess 21 group is formed on the lower surface of the tray body 12 (the lower surface of the bottom wall 15). A group of fitting protrusions 22 are formed on the upper surface of the base body 13. Three fitting recesses 21 are formed on the lower surface of the bottom wall 15 of the saucer body 12 so as to be arranged at intervals of 120 ° with the body through hole 16 as the center in the bottom view. On the upper surface of the pedestal body, three fitting protrusions 22 are formed that are arranged at intervals of 120 ° with the pedestal through hole 18 as the center in plan view. A combination of the fitting recess 21 group and the fitting protrusion 22 group constitutes the connecting portion 20.

嵌合凹所２１群と嵌合突起２２群との嵌合関係を変更することによって、受け皿本体１２と台座体１３との取り付け位相が変更される。この場合、受け皿本体１２と台座体１３との取り付け位相は、嵌合凹所２１群や嵌合突起２２群の数と同じで３パターンある。図５及び図７から分かるように平面視で切り欠き部１７から右斜め方向に凹み部１９を位置させるパターンと、図１４に示すように平面視で切り欠き部１７から左斜め方向に凹み部１９を位置させるパターンと、図１６に示すように平面視で切り欠き部１７の直下に凹み部１９を位置させるパターンとがある。受け皿本体１２と台座体１３との取り付け位相を変更することによって、これら３パターンの切り欠き部１７と凹み部１９との位置関係を選択できる。   By changing the fitting relationship between the fitting recess 21 group and the fitting protrusion 22 group, the attachment phase between the tray body 12 and the pedestal body 13 is changed. In this case, the attachment phase between the tray body 12 and the base body 13 is the same as the number of the fitting recesses 21 group and the fitting protrusions 22 group, and there are three patterns. As shown in FIGS. 5 and 7, the pattern in which the recess 19 is positioned in the right oblique direction from the notch 17 in plan view and the recess in the left oblique direction from the notch 17 in plan view as shown in FIG. 14. There are a pattern for positioning 19 and a pattern for positioning the recess 19 directly below the notch 17 in plan view as shown in FIG. By changing the mounting phase between the tray main body 12 and the pedestal 13, the positional relationship between the three patterns of the notches 17 and the recesses 19 can be selected.

上記のように構成すると、連結部２０によって互いの取り付け位相を変更して受け皿本体１２と台座体１３とを連結でき、切り欠き部１７と凹み部１９との位置関係を簡単に変更できる。従って、受け皿製造用の金型を新たに作り直したりすることなく、受け皿１１において切り欠き部１７と凹み部１９との位置関係を変更して、農産物Ａを選別仕分けする選別装置の様々なレイアウトに対して１種類の受け皿１１で柔軟に対処することが可能になる。受け皿１１の融通性を向上できる。   If comprised as mentioned above, a mutual attachment phase can be changed by the connection part 20, the saucer main body 12 and the base body 13 can be connected, and the positional relationship of the notch part 17 and the recessed part 19 can be changed easily. Accordingly, the layout of the sorting apparatus for sorting and sorting the produce A can be changed by changing the positional relationship between the notch portion 17 and the recess portion 19 in the tray 11 without recreating a mold for manufacturing the tray. On the other hand, it is possible to flexibly cope with one type of tray 11. The flexibility of the tray 11 can be improved.

もちろん、嵌合凹所２１や嵌合突起２２の並び間隔は１２０°間隔に限定するものではなく、図１８に示すように９０°間隔（嵌合凹所２１及び嵌合突起２２の組が４組）でもよいし、３０°間隔（嵌合凹所２１及び嵌合突起２２の組が１２組）や４５°間隔（嵌合凹所２１及び嵌合突起２２の組が８組）等、様々な角度間隔を採用してもよい。また、台座体１３を中空状に構成し、内部にカウンタウェイトを収容することも可能である。   Of course, the interval between the mating recesses 21 and the mating projections 22 is not limited to 120 ° intervals, but as shown in FIG. Set), 30 ° intervals (12 sets of fitting recesses 21 and fitting projections 22), 45 ° intervals (eight sets of fitting recesses 21 and fitting projections 22), etc. Various angular intervals may be employed. It is also possible to configure the pedestal 13 so as to be hollow and accommodate the counterweight therein.

更に、図１７及び図１８に示すように、台座体１３を上下複数に分離構成して、各台座体１３の外周部に搬送姿勢変更用の凹み部１９を形成してもよい。この場合、最上段の台座体１３と受け皿本体１２とに連結部２０を設けると共に、隣り合う台座体１３同士にも連結部２０を設けることになる。このように構成すると、受け皿１１において切り欠き部１７と複数の凹み部１９との位置関係を変更できるから、受け皿１１の搬送姿勢を複数回変更するような選別装置のレイアウトに対しても、１種類の受け皿１１で簡単に対処でき、受け皿１１の融通性をより一層向上できる。   Further, as shown in FIGS. 17 and 18, the base body 13 may be divided into a plurality of upper and lower parts, and a recess 19 for changing the conveying posture may be formed on the outer peripheral part of each base body 13. In this case, the connecting portion 20 is provided on the uppermost pedestal body 13 and the tray body 12, and the connecting portions 20 are also provided on the adjacent pedestal bodies 13. If comprised in this way, since the positional relationship of the notch part 17 and the several dent part 19 can be changed in the saucer 11, also with respect to the layout of the sorter which changes the conveyance attitude | position of the saucer 11 in multiple times, it is 1 The type of tray 11 can easily cope with it, and the flexibility of the tray 11 can be further improved.

次に、図９〜図１２を参照しながら、農産物Ａを選別仕分けする選別装置の構造について説明する。搬送コンベヤ５０の送り下流側には、等級（外観、糖度等の品質）や階級（サイズ）といった所定区分の農産物Ａを認識して取り出す認識センサ３１、選別シリンダ３２及び整列コンベヤ３３の組合せを複数組備えている。各整列コンベヤ３３は、受け皿１１を搬送しながら所定姿勢に揃えるためのものである。   Next, the structure of a sorting apparatus for sorting and sorting the produce A will be described with reference to FIGS. On the downstream side of the transport conveyor 50, there are a plurality of combinations of the recognition sensor 31, the sorting cylinder 32, and the alignment conveyor 33 that recognize and take out the agricultural products A of a predetermined category such as grade (quality such as appearance and sugar content) and class (size). Has a set. Each alignment conveyor 33 is for aligning in a predetermined posture while conveying the tray 11.

各整列コンベヤ３３におけるコンベヤベルト３４の幅方向一側（コンベヤベルト３４を挟んで一側方）には、受け皿１１の一側部分を他側部分よりも減速させるための速度減衰板３５を配置している。実施形態の速度減衰板３５は、摩擦係数の大きいゴム等の素材からなる板状のものであり、コンベヤベルト３５に沿って長く延びている。なお、速度減衰板３５のうち摩擦係数の大きい部分は、少なくとも受け皿１１が乗り上げる上面側であればよく、速度減衰板３５全体の摩擦係数を大きくしておく必要はない。   On one side in the width direction of the conveyor belt 34 in each alignment conveyor 33 (one side across the conveyor belt 34), a speed attenuating plate 35 for decelerating one side portion of the tray 11 relative to the other side portion is disposed. ing. The speed attenuating plate 35 of the embodiment is a plate made of a material such as rubber having a large friction coefficient, and extends long along the conveyor belt 35. Note that the portion of the speed damping plate 35 having a large friction coefficient may be at least the upper surface side on which the tray 11 rides, and it is not necessary to increase the friction coefficient of the entire speed damping plate 35.

速度減衰板３５の上面のうち搬送コンベヤ３０寄りの送り始端側は、搬送下流側に行くに従って高くなる傾斜案内面３５ａに構成している。また、傾斜案内面３５ａより搬送下流側は摩擦平坦面３５ｂに構成している。図１１及び図１２に示す実施形態では、コンベヤベルト３４の上面から速度減衰板３５の摩擦平坦面３５ｂまでの高さＨよりも、各受け皿１１における凹み部１９の上下凹み高さＨｔを高くしている。このため、図１２に示すように、受け皿１１の凹み部１９を、速度減衰板３５（特に摩擦平坦面３５ｂ）におけるコンベヤベルト３４寄りの角部３４ｃに被せて嵌め合わせた状態では、凹み部１９の横平坦面１９ｂと速度減衰板３５の摩擦平坦面３５ｂとは接触しないことになる。   Of the upper surface of the speed attenuating plate 35, the feed start end side near the conveyor 30 is configured as an inclined guide surface 35a that becomes higher as it goes downstream. Further, a downstream side of the conveyance from the inclined guide surface 35a is formed as a friction flat surface 35b. In the embodiment shown in FIG. 11 and FIG. 12, the height Ht of the upper and lower dents 19 of each recess 11 is made higher than the height H from the upper surface of the conveyor belt 34 to the friction flat surface 35 b of the speed damping plate 35. ing. For this reason, as shown in FIG. 12, in a state where the recessed portion 19 of the tray 11 is fitted on the corner portion 34c near the conveyor belt 34 in the speed damping plate 35 (particularly the friction flat surface 35b), the recessed portion 19 is fitted. The horizontal flat surface 19b and the friction flat surface 35b of the speed damping plate 35 are not in contact with each other.

コンベヤベルト３４を挟んで速度減衰板３５の反対側（他側方）には、各受け皿１１の側面に当接して凹み部１９の縦平坦面１９ａを速度減衰板３５の角部３５ｃ側に寄せるためのガイド部材３６（ガイドレール）を配置している。実施形態のガイド部材３６は、コンベヤベルト３４に沿って長く延びた形態になっているが、少なくともコンベヤベルト３４の送り終端側にあればよい。但し、コンベヤベルト３４の送り下流側において、速度減衰板３５の角部３５ｃからガイド部材３６の当接面までの距離Ｗは、各受け皿１１における凹み部１９の縦平坦面１９ａから中心を通って反対側の外周面までの幅寸法Ｗｔとほぼ同程度にしている。   On the opposite side (the other side) of the speed attenuating plate 35 across the conveyor belt 34, the vertical flat surface 19a of the recessed portion 19 is brought close to the corner 35c side of the speed attenuating plate 35 by contacting the side surface of each tray 11. For this purpose, a guide member 36 (guide rail) is disposed. Although the guide member 36 of the embodiment is configured to extend long along the conveyor belt 34, it may be at least on the feed end side of the conveyor belt 34. However, on the downstream side of the conveyor belt 34, the distance W from the corner 35 c of the speed attenuating plate 35 to the contact surface of the guide member 36 passes through the center from the vertical flat surface 19 a of the recess 19 in each tray 11. The width is approximately the same as the width dimension Wt to the outer peripheral surface on the opposite side.

各整列コンベヤ３３上の送り下流側には、各整列コンベヤ３３に送り込まれた受け皿１１の搬送を規制する（受け皿１１を一時的に堰き止める）規制部材として、例えば回動式のような可動式のストッパー３７を設けている。各ストッパー３７を規制姿勢にしておくことによって、各整列コンベヤ３３で搬送される受け皿１１を停止させ、停止した先行の受け皿１１に後続の受け皿１１を次々と追突させる。その結果、各整列コンベヤ３３上に、仕分後の受け皿１１が所定個数ずつ集積される（滞留する）。各整列コンベヤ３３上に滞留させた各受け皿１１の農産物Ａは、例えばオペレータの手作業によって透明合成樹脂製の包装パックや段ボール箱等の包装用容器にパッキング（箱詰め）される。   On the downstream side of the feeding on each alignment conveyor 33, as a regulating member that regulates the conveyance of the trays 11 sent to the respective alignment conveyors 33 (temporarily dams the trays 11), for example, a movable type such as a rotary type is movable. The stopper 37 is provided. By setting the stoppers 37 in the restricting posture, the trays 11 transported by the alignment conveyors 33 are stopped, and the succeeding trays 11 are successively bumped into the stopped preceding trays 11 one after another. As a result, a predetermined number of sorted trays 11 are accumulated (retained) on each alignment conveyor 33. The produce A in each tray 11 retained on each alignment conveyor 33 is packed (packed) into a packaging container such as a transparent synthetic resin packaging pack or cardboard box, for example, by an operator's manual operation.

以上の構成において、農産物Ａは、受け皿１１に載置し状態で選別コンベヤ３０から各整列コンベヤ３３に送られる。選別コンベヤ３０から各整列コンベヤ３３に受け皿１１を送る際は、コンベヤベルト３４と速度減衰板３５（傾斜案内面３５ａ）とに受け皿１１を跨らせる。そうすると、受け皿１１と速度減衰板３５との接触部分間には、コンベヤベルト３４による受け皿１１の搬送方向と逆向きの摩擦力が作用するので、受け皿１１の接触部分側が急激に減速する。このため、受け皿１１は、前記接触部分側を支点にして図９の反時計方向に回転しながら、コンベヤベルト３４によって搬送される。   In the above configuration, the produce A is sent from the sorting conveyor 30 to each alignment conveyor 33 while being placed on the tray 11. When the tray 11 is sent from the sorting conveyor 30 to each of the alignment conveyors 33, the tray 11 is placed over the conveyor belt 34 and the speed attenuating plate 35 (inclined guide surface 35a). Then, a frictional force opposite to the conveying direction of the tray 11 by the conveyor belt 34 acts between the contact portions of the tray 11 and the speed attenuating plate 35, so that the contact portion side of the tray 11 is decelerated rapidly. Therefore, the tray 11 is conveyed by the conveyor belt 34 while rotating counterclockwise in FIG. 9 with the contact portion side as a fulcrum.

そして、受け皿１１がガイド部材３６で速度減衰板３５寄りに案内されながら、図９の反時計方向への回転を進ませていくと、速度減衰板３５に乗り上げていた受け皿１１のうち凹み部１９を除く平坦な下面が底度減衰板３５から落ちて、コンベヤベルト３４の上面に密着する。この状態では、受け皿１１の凹み部１９と、速度減衰板３５（特に摩擦平坦面３５ｂ）の角部３５ｃとが上下方向でほぼ重なり合うため、受け皿１１の凹み部１９が速度減衰板３５の角部３５ｃに被さって嵌ることになる。その結果、受け皿１１が凹み部１９を速度減衰板３５の角部３５ｃに被せて嵌めた姿勢に揃えられて搬送される。コンベヤベルト３４とこれに並設した速度減衰板３５とに受け皿１１を跨らせて搬送するという極めて簡単な構成でありながら、受け皿１１の姿勢が的確に揃えられるのである。   Then, when the tray 11 is guided toward the speed attenuation plate 35 by the guide member 36 and is rotated in the counterclockwise direction of FIG. 9, the concave portion 19 of the tray 11 riding on the speed attenuation plate 35 is advanced. The flat lower surface excluding the bottom falls from the bottom attenuation plate 35 and comes into close contact with the upper surface of the conveyor belt 34. In this state, since the recessed portion 19 of the tray 11 and the corner portion 35c of the speed damping plate 35 (particularly the friction flat surface 35b) substantially overlap in the vertical direction, the recessed portion 19 of the tray 11 is the corner portion of the speed damping plate 35. It will fit over 35c. As a result, the tray 11 is conveyed while being aligned in a posture in which the recessed portion 19 is fitted over the corner portion 35c of the speed damping plate 35. While the conveyor belt 34 and the speed attenuating plate 35 provided in parallel with the conveyor belt 34 are transported across the tray 11, the posture of the tray 11 is precisely aligned.
