Description

この発明は、例えばリンゴ、ナシ、桃、柿、ミカン等の農作物、農産物、物品が収納された容器を反転して、該容器に収納された物品を排出する作業に用いられる容器反転排出装置に関する。 The present invention relates to a container reversing and discharging apparatus used for the work of inverting a container in which crops such as apples, pears, peaches, strawberries, mandarin oranges, agricultural products, and articles are stored and discharging the articles stored in the containers. .

従来、上述例のような多数の物品が収納された容器を上下反転して、容器に収納された物品を排出する場合、容器内部に対して物品が略一杯に収納された状態でないと、上下反転した際に物品が容器内部で移動又は転動しやすく、物品が互いに当接したり、傷付けあったりする等して、物品の品質及び鮮度、商品価値が損なわれてしまう。例えばミカン等の果物に多少の衝撃が付与されても、果物自身の強度が高く、外面を覆っている表皮が強いため、傷付きにくいが、リンゴ等の強度が低いものは、小さな衝撃が付与されるだけでも、傷付きやすく、品質及び鮮度、商品価値が損なわれるのを無くすため、現状では人為的な手作業で取り出している。 Conventionally, when a container that contains a large number of articles as in the above example is turned upside down and the articles stored in the container are discharged, When inverted, the article easily moves or rolls inside the container, and the articles are brought into contact with each other or damaged, thereby deteriorating the quality, freshness, and commercial value of the article. For example, even if some impact is given to fruits such as mandarin oranges, the strength of the fruits themselves is high and the outer skin is strong, so the skin is hard to be damaged, but apples and other fruits with low strength are given small impacts. In order to eliminate damage to quality, freshness, and commercial value, it is currently taken out by hand by hand.

また、容器に収納された物品を吸着ハンドやチャック等で保持して取り出す場合、多数の物品を容器内部に整列して配置又は収納する等して、容器に収納するときに要する手間を省くため、或いは、既存の採取にも対応するため、取り出しが容易に行えるような工夫が必要である。 In addition, when an article stored in a container is held and taken out with a suction hand or a chuck, etc., it is necessary to arrange and store a large number of articles in the container in order to save the labor required for storing in the container. Or, in order to cope with existing collection, it is necessary to devise such that it can be easily taken out.

上述の容器を上下反転する際に物品の移動や転動を少なくする装置としては、例えば容器を搬送ベルトと搬送部との間に送り込んで搬送しながら上下反転するとき、その搬送ベルトの外面に取り付けた複数の可動押圧棒を、エアチューブにより外方へ突出して容器内に挿入し、容器内に収納された物品を押え付ける特許文献１の容器反転排出装置がある。 As an apparatus for reducing the movement and rolling of articles when the container is turned upside down, for example, when the container is turned upside down while being fed and transported between the transport belt and the transport unit, the outer surface of the transport belt is There is a container reversing / discharging device of Patent Document 1 in which a plurality of attached movable pressing rods are protruded outward by an air tube and inserted into a container to press an article stored in the container.

しかし、可動押圧棒は、略容器内幅と対応する長さを有しているので、物品が偏った状態に収納されていると、可動押圧棒が一部の物品に対して密着又は押し付けられず、物品の移動や転動を防ぐことができない。また、可動押圧棒による押圧範囲が狭く、取り付けピンの長さが予め定められているので、容器内部に形成される空間の大きさに限界がある。また、搬送ベルトに取り付けた可動押圧棒を容器内に挿入するためには、反転コンベアの始端側に容器を送り込むため水平部を設けなければならず、また、搬送ベルトの内側内周に可動押圧棒を取り付ける等の構造が複雑となるような数々の問題点を有している。 However, since the movable pressing rod has a length corresponding to the inner width of the container, when the article is stored in a biased state, the movable pressing bar is in close contact with or pressed against a part of the article. Therefore, the movement and rolling of the article cannot be prevented. Moreover, since the pressing range by the movable pressing rod is narrow and the length of the mounting pin is determined in advance, there is a limit to the size of the space formed inside the container. In addition, in order to insert the movable pressing rod attached to the conveyor belt into the container, a horizontal portion must be provided to feed the container to the starting end side of the reversing conveyor, and the movable pressing rod is movable to the inner inner periphery of the conveyor belt. It has a number of problems that make the structure of attaching a rod complicated.

この発明の一実施の形態を以下図面に基づいて詳述する。
図面は、多数の物品が収納された容器を上下反転して、容器に収納された物品を排出する容器反転排出装置を示し、図１に於いて、この容器反転排出装置１は、多数の物品Ａ…が収納され上面が開口された容器Ｂ…を、略半円上を周回するように回転体２と反転コンベア３との対向面間に形成された搬送路内を周回搬送しながら上下反転して、容器Ｂに収容された物品Ａ…を排出する。 An embodiment of the present invention will be described below in detail with reference to the drawings.
The drawing shows a container reversing / discharging device that inverts a container in which a large number of articles are stored, and discharges the articles stored in the container. In FIG. The container B with the A stored therein and the upper surface opened is turned upside down while being orbitably conveyed in the conveyance path formed between the opposing surfaces of the rotating body 2 and the reversing conveyor 3 so as to circulate substantially in a semicircle. Then, the articles A contained in the container B are discharged.

上述の搬送路は、回転軸２ａを中心として回転可能に設けた回転体２と、その回転体２の略半周面と対向して架設した反転コンベア３との対向面間に形成している。 The above-mentioned conveyance path is formed between the opposing surfaces of the rotating body 2 provided to be rotatable around the rotating shaft 2a and the reversing conveyor 3 installed facing the substantially half-circumferential surface of the rotating body 2.

前述の回転体２は、側面から見て略円形又は略円筒形となるようなドラム型に形成され、回転体２の外周面（軸方向の幅）を、容器Ｂよりも幅広に形成すると共に、反転コンベア３の受けベルト３ａと略同一又は幅広となる寸法に形成している。また、回転体２の回転中心に軸支した回転軸２ａを中心として回転可能に設けると共に、上述の搬送路に沿って周回搬送される容器Ｂの搬送速度に合わせて、後述する反転コンベア３の搬送速度と略同期してモータ(図示省略)で搬送方向に回転される。 The above-described rotating body 2 is formed in a drum shape that is substantially circular or substantially cylindrical when viewed from the side, and the outer peripheral surface (width in the axial direction) of the rotating body 2 is formed wider than the container B. The size is substantially the same as or wider than the receiving belt 3 a of the reversing conveyor 3. In addition, the reversing conveyor 3 described later is provided in accordance with the conveyance speed of the container B that is circularly conveyed along the above-described conveyance path, while being provided to be rotatable around the rotation shaft 2a that is pivotally supported by the rotation center of the rotator 2. It is rotated in the transport direction by a motor (not shown) substantially in synchronization with the transport speed.

且つ、後述する収縮状態の袋状部材４が収納許容される凹部２ｂ…を、回転体２の外周面に対して径方向に向けて開口した形状に形成すると共に、上述の搬送路に沿って周回搬送される容器Ｂ…と略対向する間隔又は角度（例えば略４５度）に隔てて円周方向に対して所定間隔に隔てて複数設けている。且つ、後述するエアー供給排出装置６に接続された筒状の連通部２ｃ…を、凹部２ｂ…内の底面中央部にそれぞれ設け、例えばスポンジやウレタンゴム等の柔軟性を有する弾性体２ｄを、後述する反転コンベア３の搬送面と対向して凹部２ｂ…を除く回転体２の略外周面全体に装着している。 And the recessed part 2b ... in which the bag-shaped member 4 of the shrink state mentioned later is accommodated is formed in the shape opened toward the radial direction with respect to the outer peripheral surface of the rotary body 2, and along the above-mentioned conveyance path. A plurality are provided at predetermined intervals in the circumferential direction at intervals or angles (for example, approximately 45 degrees) substantially opposite to the containers B. Further, cylindrical communication portions 2c connected to an air supply / discharge device 6 to be described later are provided at the center of the bottom surface in the recesses 2b, respectively, and an elastic body 2d having flexibility such as sponge or urethane rubber is provided. The rotating body 2 is mounted on substantially the entire outer peripheral surface except for the recesses 2b.

上述の袋状部材４は、図２、図３にも示すように、側面から見て略蛇腹状となるような風船形態に形成され、柔軟性及び伸縮性を有する合成ゴムでゴム風船のように膨張可能に形成している。且つ、袋状部材４の開口側周縁部を、凹部２ｂの底面外周縁部に対して気密状態に密着固定し、袋状部材４の開口側周縁部よりも内側であって、袋状部材４内部と連通させて凹部２ｂの略底面中央部に設けた連通部２ｃを、袋状部材４内部にエアーＧを供給したり、袋状部材４内部からエアーＧを排出したりするエアー供給排出装置６に接続している。 As shown in FIGS. 2 and 3, the bag-like member 4 is formed in a balloon shape so as to be substantially bellows when viewed from the side, and is a synthetic rubber having flexibility and stretchability, like a rubber balloon. It is formed to be expandable. And the opening side peripheral part of the bag-like member 4 is tightly fixed in an airtight state with respect to the outer peripheral peripheral part of the bottom surface of the concave portion 2 b, and is inside the opening-side peripheral part of the bag-like member 4. An air supply / discharge device that communicates with the inside and supplies the air G to the inside of the bag-like member 4 or discharges the air G from the inside of the bag-like member 4 through the communicating portion 2c provided at the substantially bottom center portion of the recess 2b. 6 is connected.

且つ、袋状部材４の物品Ａの押え面４ａは、容器Ｂの内側壁面に沿って挿入される大きさ及び形状に形成すると共に、その容器Ｂに収納された上層側の物品Ａ…外面に沿う状態に変形可能に設けている。また、例えばスポンジやウレタンゴム等の柔軟性を有するクッション材４ｂを、後述する規制部材５上面と対向して袋状部材４の押え側内面に装着している。 Further, the pressing surface 4a of the article A of the bag-like member 4 is formed in a size and a shape to be inserted along the inner wall surface of the container B, and the upper article A stored in the container B is formed on the outer surface. It is provided so that it can be deformed along the line. Further, for example, a cushioning material 4b having flexibility such as sponge or urethane rubber is mounted on the inner surface of the presser side of the bag-like member 4 so as to face the upper surface of the regulating member 5 described later.

つまり、袋状部材４内部のエアーＧをエアー供給排出装置６で排出すると、凹部２ｂの開口側周縁部よりも内側に収納される収縮状態に袋状部材４が収縮する。また、袋状部材４内部にエアーＧをエアー供給排出装置６で供給すると、凹部２ｂの開口側周縁部よりも外側に向けて径方向に突出すると共に、容器Ｂ内部に挿入及び容器Ｂの開口が閉塞される膨張状態に袋状部材４が膨張する。要するに、袋状部材４を、容器Ｂの大きさ及び物品Ａ…の収納量に略応じて、容器Ｂに収納された上層側の物品Ａ…外面に対して押し付けられる状態に膨張させるので、容器Ｂ内部に形成される空間の大きさに略対応させることが可能である。 That is, when the air G inside the bag-shaped member 4 is discharged by the air supply / discharge device 6, the bag-shaped member 4 contracts into a contracted state that is accommodated inside the opening side peripheral edge of the recess 2b. Further, when air G is supplied into the bag-like member 4 by the air supply / discharge device 6, it protrudes radially outward from the opening side peripheral edge of the recess 2b, and is inserted into the container B and opened in the container B. The bag-like member 4 expands in an expanded state where the is closed. In short, the bag-like member 4 is expanded in a state where it is pressed against the outer surface of the article A on the upper layer side stored in the container B in accordance with the size of the container B and the storage amount of the article A. It is possible to substantially correspond to the size of the space formed inside B.

また、袋状部材４内部に供給されるエアーＧの圧力を徐々に高くするか、エアーＧの供給量を徐々に増加させる等して、袋状部材４の押え面４ａを、容器Ｂに収納された上層側の物品Ａ…外面に対してソフトに押し付け、物品Ａが押し潰されたり、変形したりしないように、物品Ａの硬さに応じて適度な圧力で押圧して、移動及び転動しないように保持することもできる。 Further, the holding surface 4a of the bag-like member 4 is stored in the container B by gradually increasing the pressure of the air G supplied into the bag-like member 4 or gradually increasing the supply amount of the air G. The upper layer side article A is softly pressed against the outer surface, and the article A is pressed with an appropriate pressure according to the hardness of the article A so that the article A is not crushed or deformed. It can also be held so as not to move.

上述の規制部材５は、図４にも示すように、上述の搬送路に沿って周回搬送される容器Ｂ…と略対向して回転体２の凹部２ｂ…にそれぞれ設けられ、板状又は棒状の縦部材５ａ…と横部材５ｂ…とを複数組み合わせて、袋状部材４の押え面４ａが回転体２の外周面と略同じ又は略同等となる収縮高さに規制されるような形状及び構造に形成され、エアーＧの排出及び供給が許容されるエアー通過部５ｃ…を規制部材５全体に複数形成すると共に、その規制状態を維持するのに必要な強度及び剛性に形成している。 As shown in FIG. 4, the above-described regulating member 5 is provided in each of the concave portions 2 b of the rotating body 2 so as to be substantially opposed to the containers B that are circulated and conveyed along the above-described conveyance path.

且つ、縦部材５ａ…及び横部材５ｂ…の下端を、袋状部材４の開口側周縁部よりも内側であって、凹部２ｂの底面中央部に設けた連通部２ｃよりも外側底面部に固定している。つまり、袋状部材４が凹部２ｂに収縮収納されるとき、その袋状部材４の押え面４ａを、回転体２の外周面と略同じ又は略同等となる高さに規制するとともに、膨張するときは容器Ｂ内部に向けて略まっすぐに挿入されるように径方向に向けてガイドする。 Further, the lower ends of the vertical members 5a and the horizontal members 5b are fixed to the inner bottom surface of the opening-like peripheral edge portion of the bag-like member 4 and to the outer bottom surface portion than the communication portion 2c provided at the center of the bottom surface of the recess 2b. is doing. That is, when the bag-like member 4 is retracted and accommodated in the recess 2b, the pressing surface 4a of the bag-like member 4 is restricted to a height that is substantially the same as or substantially equal to the outer peripheral surface of the rotating body 2 and expands. Sometimes the guide is directed in the radial direction so as to be inserted substantially straight into the container B.

前述の反転コンベア３は、前述の回転体２の略半周面と対向して張架した受けベルト３ａの搬送幅を、上述の搬送路に沿って周回搬送される容器Ｂよりも幅広に形成すると共に、回転体２外周面の横幅（軸方向の幅）と略同一又は回転体２外周面よりも幅広となる寸法に形成している。且つ、搬送路に沿って周回搬送される容器Ｂの搬送速度に合わせて、回転体２の回転速度と略同期してモータ（図示省略）で搬送方向に回転される。 The above-described reversing conveyor 3 forms the conveying width of the receiving belt 3a stretched opposite to the substantially half-circumferential surface of the above-described rotating body 2 so as to be wider than the container B that is circularly conveyed along the above-described conveying path. At the same time, the width of the outer peripheral surface of the rotating body 2 (the width in the axial direction) is substantially the same as the width of the outer peripheral surface of the rotating body 2. And according to the conveyance speed of the container B circulated around the conveyance path, it is rotated in the conveyance direction by a motor (not shown) substantially in synchronization with the rotation speed of the rotating body 2.

且つ、容器Ｂの底部側後端面に係止される凸状の係止部３ｂを受けベルト３ａの載置面上に突設すると共に、その係止部３ｂ…を、回転体２外周面に形成した凹部２ｂ…と略対向する位置に容器Ｂ…が位置規制される前後間隔に隔てて受けベルト３ａの全長に対して多数設けている。また、ベルトコンベア型の反転コンベア３に代えて、例えばローラコンベアやチェーンコンベア、スラストコンベア等の搬送装置で構成することもできる。 Further, the convex locking portion 3b locked to the bottom side rear end surface of the container B is projected on the mounting surface of the belt 3a, and the locking portion 3b. A large number of the receiving belts 3a are provided with respect to the entire length of the receiving belt 3a at a position substantially opposite to the formed recesses 2b. Moreover, it can replace with the belt conveyor type inversion conveyor 3, and can also be comprised with conveying apparatuses, such as a roller conveyor, a chain conveyor, a thrust conveyor, for example.

次に、ａ点通過時点で、袋状部材４内部と連通するエアー室６ａが負圧室６ｃから加圧室６ｂへ切換わり、図２にも示すように、袋状部材４を、容器Ｂの開口全体が閉塞される膨張状態に膨張させながら、その袋状部材４の押え面４ａを容器Ｂの内側壁面に沿って挿入し、容器Ｂに収納された上層側の物品Ａ…上面に沿う状態に変形させるようにして密着させ、全物品Ａ…を、袋状部材４の膨張によりソフトに押え込んで、移動や転動しないように押え込む。 Next, when the point a is passed, the air chamber 6a communicating with the inside of the bag-shaped member 4 is switched from the negative pressure chamber 6c to the pressure chamber 6b, and as shown in FIG. The presser surface 4a of the bag-like member 4 is inserted along the inner wall surface of the container B while being inflated so that the entire opening of the container is closed. The articles A are brought into close contact with each other in a deformed state, and the entire article A is pressed softly by the expansion of the bag-like member 4 so as not to move or roll.

次に、図５にも示すように、容器Ｂに収納された全物品Ａ…を袋状部材４で押え込んだまま、ｂ点、ｃ点、ｄ点の順に周回移動させ、ｄ点を通過後に、上下反転（略１８０度）された容器Ｂ内部の全物品Ａ…を押圧保持する袋状部材４内部と連通する。エアー室６ａが加圧室６ｂから負圧室６ｃに切換わって、袋状部材４内部のエアーＧをエアー吸引源（図示省略）で吸引するか、大気側に開放する等して排出し、袋状部材４を、エアーＧの排出及び物品Ａ…の重量を利用して徐々に収縮させ、全物品Ａ…の押え込みを解除する。 Next, as shown in FIG. 5, all the articles A contained in the container B are moved in the order of b point, c point, and d point while being held down by the bag-like member 4 and pass through the d point. After that, it communicates with the inside of the bag-like member 4 that presses and holds all articles A in the container B that is turned upside down (approximately 180 degrees). The air chamber 6a is switched from the pressurizing chamber 6b to the negative pressure chamber 6c, and the air G inside the bag-like member 4 is sucked by an air suction source (not shown) or discharged to the atmosphere side or the like, The bag-like member 4 is gradually shrunk using the discharge of the air G and the weight of the articles A to release the pressing of all the articles A.

次に、図３にも示すように、袋状部材４を容器Ｂ内部から抜き取りながら、回転体２の凹部２ｂ内部に向けて収納される収縮状態に収縮させ、袋状部材４の上面側押え面４ａを、回転体２外周面と略同じ又は略同等となる高さに規制部材５で支持する。 Next, as shown in FIG. 3, while the bag-like member 4 is pulled out from the inside of the container B, the bag-like member 4 is contracted into a contracted state stored toward the inside of the concave portion 2 b of the rotating body 2. The surface 4a is supported by the regulating member 5 at a height that is substantially the same or substantially the same as the outer peripheral surface of the rotating body 2.

Further, since it is regulated by the regulating member 5, there is almost no step between the pressing surface 4 a of the bag-like member 4 and the outer peripheral surface of the rotating body 2, and the impact applied at the time of transfer is reduced, and it is discharged smoothly without being damaged. And can be released.

また、衝撃に弱い果物（リンゴや梨、トマト等）を容器Ｂから排出するための装置として使用でき、ランダムに排出することができる。また、既存の人為的な排出作業を省力化して、作業の能率アップも図ることができる。 Moreover, it can use as an apparatus for discharging | emitting the fruit (an apple, a pear, a tomato, etc.) weak to an impact from the container B, and can discharge | emit at random. In addition, the efficiency of work can be improved by saving the labor of the existing artificial discharge work.

他の実施例としては、容器Ｂから排出される物品Ａ…を受け止める受け部は、一体の風船のように膨張する袋状部材４で構成しているが、例えば複数に分割した風船、スポンジ等の柔軟物を容器Ｂ内部に出し入れしてもよく、袋状部材４を容器Ｂ内部に挿入して、全物品Ａ…を押え込むものであれば、実施例の袋状部材４のみに限定されるものではない。 As another embodiment, the receiving portion for receiving the article A ... discharged from the container B is composed of a bag-like member 4 that expands like an integral balloon. The flexible material may be taken in and out of the container B, and is limited to the bag-like member 4 of the embodiment as long as the bag-like member 4 is inserted into the container B and all the articles A are pressed. It is not something.

また、袋状部材４内部に対するエアーＧの供給及び排出の制御は、エアー室６ａの加圧室６ｂ及び負圧室６ｃと、エアー供給源及びエアー吸引源との間に設けた連通孔６ｈ…の相対的な回転位置の変化による穴径で制御しているが、これも流量計等の別手段で制御することもできる。 Further, the control of the supply and discharge of the air G to and from the bag-like member 4 is performed by a communication hole 6h provided between the pressurizing chamber 6b and the negative pressure chamber 6c of the air chamber 6a and the air supply source and the air suction source.
