なお、空の製品箱１３は、プールコンベア３の先端部上方で、プールコンベア３を横切るように配置した空箱搬送コンベア１４により搬送され、作業者Ｗがこの空箱搬送コンベア１４から空の製品箱１３を取り出して空いている昇降台１１、１２に載置する。 In addition, the empty product box 13 is conveyed by the empty box conveyance conveyor 14 arrange | positioned so that the pool conveyor 3 may be crossed above the front-end | tip part of the pool conveyor 3, and the operator W is empty product from this empty box conveyance conveyor 14 The box 13 is taken out and placed on the empty lifts 11 and 12.

次に、農産物の箱詰め送り出し装置を図２から図４を参照して以下に説明する。 Next, an agricultural product boxing and feeding apparatus will be described below with reference to FIGS.

上記した昇降台装置１０は、装置本体１５を矩形フレーム形状に形成し、長さ方向の前後に第１昇降台シャフト部１７と第２昇降台シャフト部１８を設け、第１昇降台シャフト部１７内に第１昇降台１１を第１昇降機構１９により昇降可能とし、また第２昇降台シャフト部１８内に第２昇降台１２を第２昇降機構２０により昇降可能としている。 The above-described lifting platform device 10 has a device body 15 formed in a rectangular frame shape, and is provided with a first lifting platform shaft portion 17 and a second lifting platform shaft portion 18 in the longitudinal direction, and the first lifting platform shaft portion 17. The first lifting platform 11 can be lifted and lowered by the first lifting mechanism 19, and the second lifting platform 12 can be lifted and lowered by the second lifting mechanism 20 in the second lifting shaft portion 18.

第１昇降台シャフト部１７と第２昇降台シャフト部１８とはプールコンベア３の搬送方向に沿って前後に配置した縦列配置構成であり、第２昇降台シャフト部１８の下端にはローラコンベア構造の製品箱送り出しコンベア２１の搬送始端側が位置し、製品箱送り出しコンベア２１は選別コンベア１側を前方方向として駆動される。 The first lifting / lowering shaft portion 17 and the second lifting / lowering shaft portion 18 are arranged in tandem along the transport direction of the pool conveyor 3, and a roller conveyor structure is provided at the lower end of the second lifting / lowering shaft portion 18. The product box delivery conveyor 21 is positioned at the conveyance start end side, and the product box delivery conveyor 21 is driven with the sorting conveyor 1 side as the forward direction.

製品箱送り出しコンベア２１の搬送先端部にはストッパ２２が配置され、このストッパ２２よりも搬送方向下流側には、製品箱送り出しコンベア２１の搬送速度よりも高速駆動される高速送り出しローラ２３を設け、ストッパ２２による製品箱の停止を解除すると、この高速送り出しローラ２３により増速された搬送速度で製品搬送コンベア２４に製品箱が合流する。製品搬送コンベア２４はプールコンベア３を横切るようにして配置されている。 A stopper 22 is disposed at the conveyance tip of the product box delivery conveyor 21, and a high-speed delivery roller 23 that is driven at a higher speed than the conveyance speed of the product box delivery conveyor 21 is provided downstream of the stopper 22 in the conveyance direction. When the stop of the product box by the stopper 22 is released, the product box joins the product transport conveyor 24 at the transport speed increased by the high-speed feed roller 23. The product conveying conveyor 24 is arranged so as to cross the pool conveyor 3.

第１昇降台１１は、フレーム部１１ａの上部に複数のローラ１１ｂを前後方向並列に配置した送り出しローラコンベアを構成しており、該複数のローラ１１ｂからなる送り出しローラコンベアは製品箱送り出しコンベア２１の搬送方向と同方向に製品箱を送り出し可能としている。すなわち、第１昇降台１１に設けた送り出しローラコンベアは、製品箱送り出しコンベア２１の一部を構成するとも言え、また第１昇降台１１に載置した製品箱１３を製品箱送り出しコンベア２１に移載する移載手段をなすものとも言える。 The first elevator 11 constitutes a delivery roller conveyor in which a plurality of rollers 11b are arranged in parallel in the front-rear direction on the upper portion of the frame portion 11a, and the delivery roller conveyor composed of the plurality of rollers 11b is the product box delivery conveyor 21. The product box can be sent out in the same direction as the transport direction. That is, it can be said that the delivery roller conveyor provided on the first elevator 11 constitutes a part of the product box delivery conveyor 21, and the product box 13 placed on the first elevator 11 is transferred to the product box delivery conveyor 21. It can be said that it constitutes a transfer means for loading.

第１昇降台１１を昇降駆動する第１昇降機構１９は、矩形フレーム形状に形成された装置本体１５の後端フレーム部１５ａに取り付けられ、この昇降台１１を片持ち支持状態で昇降駆動する。第１昇降機構１９は、後端フレーム部１５ａの上下方向に取り付けられた左右一対のガイド軸１９ａと、左右一対のガイド軸１９ａの間に配置された例えばエアー駆動式のロッドレスシリンダ１９ｂとにより構成されている。第１昇降台１１のフレーム部１１ａの後端には、左右一対のガイド軸１９ａに外装される軸受部１１ｃが左右に設けられている。 The first elevating mechanism 19 for raising and lowering the first elevating platform 11 is attached to the rear end frame portion 15a of the apparatus main body 15 formed in a rectangular frame shape, and elevates and drives the elevating platform 11 in a cantilever supported state. The first elevating mechanism 19 includes a pair of left and right guide shafts 19a attached in the vertical direction of the rear end frame portion 15a and, for example, an air-driven rodless cylinder 19b disposed between the pair of left and right guide shafts 19a. It is configured. At the rear end of the frame portion 11 a of the first lifting platform 11, bearing portions 11 c are provided on the left and right sides that are covered by a pair of left and right guide shafts 19 a.

エアー駆動式のロッドレスシリンダ１９ｂは、装置本体１５の後端フレーム部１５ａの上下端間に取り付けられたシリンダ本体１９ｃに対して移動体１９ｄが移動可能に取り付けられ、シリンダ本体１９ｃに圧縮空気を供給し、供給経路を切り替えることにより、移動体１９ｄを装置本体１５の上下方向に移動可能とすると共に、上端位置から所定ピッチで複数段にわたり降下可能としている。そして、この移動体１９ｄに第１昇降台載置台１１のフレーム部１１ａを取り付けている。 In the air-driven rodless cylinder 19b, a movable body 19d is movably attached to a cylinder body 19c attached between the upper and lower ends of the rear end frame portion 15a of the apparatus body 15, and compressed air is supplied to the cylinder body 19c. By supplying and switching the supply path, the movable body 19d can be moved in the vertical direction of the apparatus main body 15, and can be lowered over a plurality of stages at a predetermined pitch from the upper end position. And the frame part 11a of the 1st lifting stand mounting base 11 is attached to this moving body 19d.

なお、第２昇降台１２の第２昇降機構２０も第１昇降機構１９と同様の構成を有し、第２昇降機構２０が装置本体１５の後端フレーム部１５ａに取り付けられているのに対し、第２昇降機構２０は装置本体１５の横側フレーム部１５ｂに取り付けている点が異なるだけなので、第２昇降機構２０の各構成部材は第１昇降機構１９の各構成部材と同じ符号を付してその説明を省略する。 The second lifting mechanism 20 of the second lifting platform 12 has the same configuration as the first lifting mechanism 19, whereas the second lifting mechanism 20 is attached to the rear end frame portion 15 a of the apparatus body 15. The second elevating mechanism 20 is different only in that the second elevating mechanism 20 is attached to the lateral frame portion 15b of the apparatus main body 15. Therefore, the description is omitted.

また、第１昇降台１１が下端の送り出し位置に降下した状態で、ローラ１１ｂは送り出しコンベア２１のローラと同一面となる。この状態で、装置本体１５の第１昇降台シャフト部１７の下端部に設けられた回転駆動する伝動ローラ（不図示）にローラ１１ｂが連結されて駆動力が伝達され、複数のローラ１１ｂにより製品箱を送り出しコンベア２１に向けて搬送する。 In addition, the roller 11b is flush with the rollers of the delivery conveyor 21 in a state where the first elevator 11 is lowered to the delivery position at the lower end. In this state, the roller 11b is coupled to a rotationally driven transmission roller (not shown) provided at the lower end of the first lifting / lowering shaft portion 17 of the apparatus main body 15, and the driving force is transmitted to the product by the plurality of rollers 11b. The box is conveyed toward the delivery conveyor 21.

第１昇降台１１には、製品箱１３が載置され、農産物Ｖの箱詰めを行うが、一箱の箱詰めが終了すると、その上に空箱を積み農産物Ｖの箱詰めを行う。第１段目の空の製品箱１３を第１昇降台１１に載置した状態において、装置本体１５の上端面に空の製品箱１３の上端が一致するようにロッドレスシリンダ１９ｂの上端停止位置（箱詰め位置）を設定している。そして、２段目、３段目と空の製品箱１３を載せる際に、第１昇降台シャフト部１７に対応した装置本体１５の上端に設けた起動スイッチ２５ａをオンすると、所定の距離だけ降下して停止し、２段目、３段目の空の製品箱１３の上端を装置本体１５の上端と同じレベルに一致させる。ロッドレスシリンダ１９ｂの降下する段数は段数セレクタ２５ｂにより選択可能としている。また一度に降下する距離も調節できるようになっている。本実施例では最大積載段数を３段に設定している。なお、停止スイッチボタン２５ｄをオンすると、第１昇降台１１の昇降動作を停止できるようにしている。 A product box 13 is placed on the first lifting platform 11 and boxes the agricultural products V. When the boxing of one box is completed, empty boxes are stacked on the boxes to pack the agricultural products V. In a state in which the first-stage empty product box 13 is placed on the first lifting platform 11, the upper end stop position of the rodless cylinder 19b so that the upper end of the empty product box 13 coincides with the upper end surface of the apparatus body 15. (Boxing position) is set. When the second and third stages and the empty product box 13 are placed, if the start switch 25a provided on the upper end of the apparatus body 15 corresponding to the first lifting / lowering shaft portion 17 is turned on, it is lowered by a predetermined distance. Then, the upper ends of the second and third empty product boxes 13 are made to coincide with the upper end of the apparatus main body 15. The number of steps that the rodless cylinder 19b descends can be selected by the step number selector 25b. You can also adjust the distance to descend at once. In this embodiment, the maximum number of loading stages is set to three. When the stop switch button 25d is turned on, the lifting operation of the first lifting platform 11 can be stopped.

また、装置本体１５の上端部には、第１昇降台シャフト部１７および第２昇降台シャフト部１８に対応して製品箱１３の側面に箱詰めする農産物の階級、等級を印字する印字装置２６が設けられ、印字スイッチボタン２５ｃをオンすると、印字装置２６により製品箱１３の側面に階級、等級が印字される。 In addition, a printing device 26 for printing the class and grade of agricultural products to be boxed on the side surface of the product box 13 corresponding to the first lifting platform shaft portion 17 and the second lifting platform shaft portion 18 is provided at the upper end portion of the apparatus body 15. When the printing switch button 25c is turned on, the class and grade are printed on the side surface of the product box 13 by the printing device 26.

図４に示すように、第２昇降台１２は、複数の爪部材１２ａで構成される水平フォーク１２ｂをその基部側で第２昇降機構２０のロッドレスシリンダ１９ｂに対して昇降する移動体１９ｄに取り付け、水平フォーク１２ｂの基部側の前後に設けた軸受部１２ｃが第２昇降機構２０のガイド軸１９ａにそれぞれ外装している。 As shown in FIG. 4, the second lifting platform 12 is a moving body 19d that moves up and down a horizontal fork 12b composed of a plurality of claw members 12a with respect to the rodless cylinder 19b of the second lifting mechanism 20 on its base side. The bearings 12c provided at the front and rear of the base fork of the horizontal fork 12b are mounted on the guide shaft 19a of the second lifting mechanism 20 respectively.

水平フォーク１２ｂを構成する爪部材１２ａは、製品箱送り出しコンベア２１のローラ２１ａと平行に延びており、図３に示すように、製品箱送り出しコンベア２１のローラの間に設けた凹部２１ｂ内に爪部材１２ａを没入可能とし、第２昇降台１２が最下位の送り出し位置に降下した状態で爪部材１２ａの上面が製品箱送り出しコンベア２１の搬送面よりも下方になる。したがって、第２昇降台１２上に載置した製品箱は、第２昇降台１２が最下位の位置まで降下すると、第２昇降台１２上の製品箱１３は製品箱送り出しコンベア２１の搬送面に移載されることになり、製品箱送り出しコンベア２１により製品搬送コンベア２４に向けて送り出される。すなわち、第２昇降台１２の載置面をなす水平フォーク１２ｂは、第２昇降台１２に載置する製品箱１３を製品箱送り出しコンベア２１に移載する移載手段と言える。 The claw member 12a constituting the horizontal fork 12b extends in parallel with the roller 21a of the product box delivery conveyor 21. As shown in FIG. 3, the claw member 12a is inserted into the recess 21b provided between the rollers of the product box delivery conveyor 21. The member 12a can be immersed, and the upper surface of the claw member 12a is lower than the conveying surface of the product box delivery conveyor 21 in a state where the second lifting platform 12 is lowered to the lowest delivery position. Therefore, the product box placed on the second lifting platform 12 is moved to the transport surface of the product box delivery conveyor 21 when the second lifting platform 12 is lowered to the lowest position. The product is transferred and sent out by the product box delivery conveyor 21 toward the product conveyance conveyor 24. That is, it can be said that the horizontal fork 12 b forming the mounting surface of the second lifting platform 12 is a transfer means for transferring the product box 13 mounted on the second lifting platform 12 to the product box delivery conveyor 21.

本実施例において、第１昇降台１１および第２昇降台１２にそれぞれ積載できる製品箱１３の最大積載段数を３段に設定し、第１昇降台１１および第２昇降台１２に載置する製品箱１３は区別せずに共通のものを使用している。 In this embodiment, the maximum number of loading stages of the product boxes 13 that can be loaded on the first lifting platform 11 and the second lifting platform 12 is set to three, and the products placed on the first lifting platform 11 and the second lifting platform 12 are set. A common box 13 is used without distinction.

図３に示す箱詰め送り出しの状態は、第１昇降台１１では１段目の箱詰めを行い、第２昇降台１２では３段目の箱詰めを行っている。製品箱１３を最大の３段に積載した状態で第２昇降台１２と送り出しコンベア２１の搬送面との間には、製品箱を３段に積載した最大段積高さよりも高い高さを確保している。 In the state of boxed delivery shown in FIG. 3, the first lifting / lowering table 11 performs the first-stage boxing, and the second lifting / lowering table 12 performs the third-stage packing. With the product boxes 13 stacked in the maximum three stages, a height higher than the maximum stack height in which the product boxes are stacked in three stages is secured between the second lifting platform 12 and the transfer surface of the delivery conveyor 21. is doing.

このため、第１昇降台１１において製品箱１３を３段に積んでの箱詰め作業が終了し、第１昇降台１１を最下位の送り出し位置まで降下させ、第１昇降台１１の上部に設けている複数のローラ１１ｂの駆動により３段重ねの製品箱１３を送り出しコンベア２１に向けて送り出しても、第２昇降台１２の下方には３段重ねの製品箱１３を通過可能とする高さが確保されているので、第１昇降台１１から送り出された３段重ねの製品箱１３は、第２昇降台１２上での農産物Ｖの箱詰め作業が支障となることなく製品搬送コンベア２４へと搬送できる。 For this reason, the boxing operation in which the product boxes 13 are stacked in three stages on the first lifting platform 11 is finished, the first lifting platform 11 is lowered to the lowest delivery position, and is provided on the upper portion of the first lifting platform 11. Even when the three-tiered product boxes 13 are sent out toward the conveyor 21 by driving the plurality of rollers 11b, the height that allows the three-tiered product boxes 13 to pass under the second lifting platform 12 is low. As a result, the three-tiered product box 13 delivered from the first lifting platform 11 is transported to the product transporting conveyor 24 without hindering the boxing operation of the agricultural products V on the second lifting platform 12. it can.

なお、第１昇降台１１から送り出された製品箱１３が第２昇降台１２の真下を通過している場合に、第２昇降台１２用の起動スイッチ２５ａをオンとしても、第１昇降台１１から送り出された製品箱１３の通過をセンサ（不図示）が検知した後に第２昇降台１２の降下を開始させる。 In addition, when the product box 13 sent out from the first lifting platform 11 passes right under the second lifting platform 12, the first lifting platform 11 can be turned on even if the start switch 25a for the second lifting platform 12 is turned on. After the sensor (not shown) detects the passage of the product box 13 sent out from, the lowering of the second lifting platform 12 is started.

このように、一つの製品箱送り出しコンベア２１に対し、製品箱送り出しコンベア２１の搬送方向に沿って第１昇降台１１と第２昇降台１２を縦列配置しても、搬送方向上流側に位置する第１昇降台１１で農産物Ｖを箱詰めした製品箱１３を搬送方向下流側に位置する第２昇降台１２の箱詰め作業中でも製品搬送コンベア２４に向けて送り出すことができる。 Thus, even if the 1st raising / lowering stand 11 and the 2nd raising / lowering stand 12 are arranged in a line along the conveyance direction of the product box delivery conveyor 21 with respect to one product box delivery conveyor 21, it is located in the conveyance direction upstream. The product box 13 in which the agricultural products V are packed in the first lifting platform 11 can be sent out toward the product transporting conveyor 24 even during the boxing operation of the second lifting platform 12 located on the downstream side in the transport direction.

ここで、従来では１条のプールコンベアの側方に一つの昇降台を配置しかできず、また受皿リターンコンベアを必要とすることから、一箇所の箱詰め作業部に対し、１条のプールコンベアの幅＋１条の受皿リターンコンベアの幅＋昇降台の幅を最低限必要とし、２つのプールコンベアによる箱詰めを行うには、この倍の幅を必要としていた。 Here, conventionally, only one lifting platform can be arranged on the side of the single pool conveyor, and a tray return conveyor is required. The width + the width of the tray return conveyor + the width of the lifting platform is required at a minimum, and this double width is necessary for boxing by two pool conveyors.

これに対し、本実施例では、一箇所の箱詰め作業部６において２つのプールコンベアに対する箱詰めを行うことができ、これに要する箱詰め作業部６の幅は、２条のプールコンベアの幅＋１条の受皿リターンコンベアの幅＋昇降台の幅で済む。 On the other hand, in the present embodiment, it is possible to perform boxing for two pool conveyors in one boxing operation unit 6, and the width of the boxing operation unit 6 required for this is the width of the two pool conveyors + 1. The width of the tray return conveyor + the width of the lifting platform is sufficient.

したがって、本実施例の箱詰め送り出し装置を採用することで、２つのプールコンベアに対する箱詰め送り出しに要する幅は、従来よりもリターンコンベアの幅と昇降台の幅の和だけ狭くて済む。 Therefore, by adopting the boxing and feeding device of the present embodiment, the width required for boxing and feeding to the two pool conveyors can be made smaller by the sum of the width of the return conveyor and the width of the lifting platform.

農産物の選別箱詰め装置を備えた施設では、多数条のプールコンベアが設けられているので、本実施例によれば選別コンベアの搬送方向の長さを短くすることができる。 In a facility equipped with a sorting box device for agricultural products, a large number of pool conveyors are provided, and according to this embodiment, the length of the sorting conveyor in the transport direction can be shortened.

なお、本実施例において、第１昇降機構１９は装置本体１５の後端フレーム部に取り付けているが、第２昇降機構２０と同様に装置本体１５の横側フレーム部１５ｂに設けても良く、第１昇降台１１を第２昇降台１２と同様にフォーク形状としても良い。この場合、製品箱送り出しコンベア２１の搬送始端部を第１昇降台シャフト部１７から開始させる。この場合、フォークの爪部材がローラの間に没入できるようにする。 In the present embodiment, the first elevating mechanism 19 is attached to the rear end frame portion of the apparatus main body 15. However, like the second elevating mechanism 20, the first elevating mechanism 19 may be provided on the side frame section 15b of the apparatus main body 15. The first lifting platform 11 may have a fork shape similar to the second lifting platform 12. In this case, the conveyance start end portion of the product box delivery conveyor 21 is started from the first lifting platform shaft portion 17. In this case, the claw member of the fork can be immersed between the rollers.

第２実施例
図５は本発明の第２実施例を示す。 Second Embodiment FIG. 5 shows a second embodiment of the present invention.

上記した第１実施例の箱詰め送り出し装置は、２条のプールコンベア３に対応して第１昇降台１１と第２昇降台１２との２つの昇降台を送り出しコンベア２１の搬送方向に沿って縦列配置しているが、本実施例では、３条のプールコンベア３に対応して、第２昇降台１２の前に第３昇降台２７を設け、３つの昇降台を送り出しコンベア２１の送り出し方向に沿って縦列配置している。 The boxing and feeding device according to the first embodiment described above corresponds to two pool conveyors 3, and the two lifting platforms, the first lifting platform 11 and the second lifting platform 12, are arranged vertically along the conveying direction of the delivery conveyor 21. In this embodiment, a third elevator 27 is provided in front of the second elevator 12 corresponding to the three pool conveyors 3, and the three elevators are arranged in the delivery direction of the delivery conveyor 21. It is arranged in tandem along.

本実施例では、第１昇降台１１の第１昇降機構１９と、第２昇降台１２の第２昇降機構２０は第１実施例と同様とし、第３昇降台２７は第２昇降台１２と同様のフォーク形状とし、第３昇降台２７を昇降駆動する第３昇降機構（不図示）は第２昇降機構２０と同じ機構を用いている。 In this embodiment, the first lifting mechanism 19 of the first lifting platform 11 and the second lifting mechanism 20 of the second lifting platform 12 are the same as in the first embodiment, and the third lifting platform 27 is the same as the second lifting platform 12. A third elevating mechanism (not shown) that has the same fork shape and drives the third elevating platform 27 to move up and down uses the same mechanism as the second elevating mechanism 20.

また、第１実施例では、一つの箱詰め部を等級別に分けているが、本実施例では階級別に分けており、図５に示す箱詰め部９は例えば等級「秀」を取り扱い、この箱詰め部９における右側の箱詰め作業部６は、３条のプールコンベア３が階級「Ｍ」「Ｌ」「２Ｌ」の農産物Ｖがそれぞれ仕分け排出され、第１昇降台１１上の製品箱１３には階級「Ｍ」の農産物Ｖを１８玉、第２昇降台１２上の製品箱１３には階級「Ｌ」の農産物Ｖを１２玉、第３昇降台２７上の製品箱１３には階級「２Ｌ」の農産物Ｖを１０玉箱詰めする。なお、第３昇降台２７上の製品箱１３に等級「秀」、階級「２Ｌ」の印字を行う印字装置（不図示）を設けるのも第１実施例と同様である。 Further, in the first embodiment, one boxing portion is divided by grade, but in this embodiment, it is divided by rank, and the boxing portion 9 shown in FIG. In the right boxing work section 6, the three pool conveyors 3 respectively sort and discharge the farm products V of the classes “M”, “L” and “2L”, and the product box 13 on the first lifting platform 11 has a class “M” 18 products, the product box 13 on the second lifting platform 12 has 12 products of the class “L”, and the product box 13 on the third lifting platform 27 has the products V of the class “2L”. 10 boxes. As in the first embodiment, a printing device (not shown) for printing the grades “excellent” and class “2L” is provided on the product box 13 on the third lifting platform 27.

本実施例の場合でも、第２昇降台１２と第３昇降台２７とは共に最大積載段数を３段とし、第３昇降台２７が製品箱１３を３段に重ねた位置で農産物の箱詰め作業を行っている状態で、第１昇降台１１および第２昇降台１２に積み重ねられた３段の製品箱１３が製品箱送り出しコンベア２１に乗って第３昇降台２７の真下を通過可能としている。 Even in the case of the present embodiment, both the second lifting platform 12 and the third lifting platform 27 have a maximum number of loading stages of 3, and the third lifting platform 27 is packed with agricultural products at a position where the product boxes 13 are stacked in three stages. In this state, the three-stage product boxes 13 stacked on the first elevator platform 11 and the second elevator platform 12 can ride on the product box delivery conveyor 21 and pass directly under the third elevator platform 27.

このように、３つの昇降台を縦列配置しても、１条の製品箱送り出しコンベア２１を用いて各昇降台に載置している農産物が箱詰めされた製品箱１３を製品搬送コンベア２４に送り出すことができる。 In this way, even if the three elevators are arranged in tandem, the product boxes 13 in which the agricultural products placed on the elevators are boxed are sent to the product conveyor 24 using the single product box delivery conveyor 21. be able to.

なお、上記した第１実施例および第２実施例において、各箱詰め作業部６におけるプールコンベア３の条数を同じ条数とする必要はなく、２条と３条とを混在させても良い。 In the first embodiment and the second embodiment described above, it is not necessary that the number of the pool conveyors 3 in each boxing work section 6 is the same number, and two and three may be mixed.

また、一箇所の箱詰め作業部６において、プールコンベア３の条数を３条とし、昇降台を２台縦列配置し、例えば仕分け個数の少ない農産物Ｖを３条のプールコンベアの一つに仕分けるようにし、このプールコンベア３に箱詰め個数の農産物Ｖがプールされると、２台の昇降台に空の製品箱１３を載せ、そこに仕分け個数の少ない農産物Ｖを箱詰めし、印字装置を用いるかあるいはスタンプなどを用いて手作業で等級と階級を製品箱の側面に印字するようにしても良い。 Moreover, in the boxing operation part 6 in one place, the number of strips of the pool conveyor 3 is three, and two lifting platforms are arranged in tandem so that, for example, the farm products V with a small number of sorting are sorted into one of the three strip conveyors. When the agricultural products V of the boxed quantity are pooled on the pool conveyor 3, empty product boxes 13 are placed on the two elevators, and the agricultural products V with a small number of sorts are boxed, and a printing device is used. You may make it print a grade and a class on the side of a product box by hand using a stamp.

あるいは、仕分け個数の多い農産物Ｖを３条のプールコンベア３の内、２条のプールコンベア３にプールさせるようにしても良い。この場合、縦列配置した２台の昇降台上の製品箱１３に同じ等階級の農産物Ｖを箱詰めし、大量に仕分けられた農産物の箱詰め効率を高めるようにしても良い。勿論、プールコンベア３の条数よりも縦列配置する昇降台の数を多くして予備の昇降台を用意しても良く、選別作業中においてプールコンベア３に排出する仕分け区分を一時的に変更する場合、今までの箱詰め送り出し作業を中断し、変更後の仕分け区分の農産物を予備の昇降台に載せた製品箱に箱詰めし、この割り込ませた仕分け区分の農産物の箱詰め送り出しが終了すると、再び元の仕分け区分による選別に戻り、箱詰め送り出しを再開する。 Or you may make it pool the agricultural product V with many sorting numbers on the two pool conveyors 3 among the three pool conveyors 3. FIG. In this case, the product boxes 13 on the two elevators arranged in tandem may be packed with agricultural products V of the same class so as to increase the packaging efficiency of the agricultural products sorted in large quantities. Of course, it is also possible to prepare a spare lifting platform by increasing the number of lifting platforms arranged in tandem rather than the number of strips of the pool conveyor 3, and temporarily change the sorting category discharged to the pool conveyor 3 during the sorting operation.
