Description
ちなみに、特許文献1では、下流コンベヤとして本流コンベヤ12と分岐側コンベヤ13とが設けられており、これら本流コンベヤ12と分岐側コンベヤ13とは、搬送方向が互いに30°異なっている。そして、特許文献1に記載の搬送コンベヤ(ベルトジャンクションコンベヤ10)は、物品を本流コンベヤ12に受け渡すことができる第1搬送状態や、物品を分岐側コンベヤ13に受け渡すことができる第2搬送状態に切り換え自在に構成して、搬送方向が異なる本流コンベヤ12と分岐側コンベヤ13との両方に物品を適切に搬送できるようになっている。
そして、搬送コンベヤを、第一方向側に下流コンベヤが位置する状態で設け、第1搬送状態から、第1搬送用巻回体を縦軸心周りに時計回りに30°揺動させ、その第1搬送用巻回体の揺動により生じた無端ベルトにおける搬送部分の伸縮を、第1中継用巻回体を縦軸心周りに反時計回りに30°揺動させることで吸収して、第2搬送状態に切り換えるように構成されている。
前記複数の巻回体として、前記無端ベルトにおける前記搬送面を形成する搬送部分の搬送方向の一方側である第一方向側の端部に位置する第1搬送用巻回体と、前記搬送部分の搬送方向の他方側である第二方向側の端部に位置する第2搬送用巻回体と、前記第1搬送用巻回体及び前記第2搬送用巻回体より下方に位置し且つ搬送方向において前記第1搬送用巻回体と前記第2搬送用巻回体との間に位置する第1中継用巻回体と、前記第1搬送用巻回体及び前記第2搬送用巻回体より下方に位置し且つ搬送方向において前記第1中継用巻回体より前記第二方向側に位置する第2中継用巻回体と、が設けられ、前記無端ベルトは、前記第1搬送用巻回体、前記第2搬送用巻回体、前記第1中継用巻回体、前記第2中継用巻回体、前記第1搬送用巻回体の順に巻回され、前記第2搬送用巻回体、前記第1中継用巻回体及び前記第2中継用巻回体が、前記第二方向側の端部に位置する上下方向に沿う縦軸心周りに揺動自在に支持され、前記第2搬送用巻回体と前記第2中継用巻回体とを前記縦軸心周りに一体的に揺動させ且つ前記第2搬送用巻回体及び前記第2中継用巻回体が揺動する方向にこれら前記第2搬送用巻回体及び前記第2中継用巻回体の揺動量より多く前記第1中継用巻回体を前記縦軸心周りに揺動させるべく、前記第2搬送用巻回体と前記第1中継用巻回体と前記第2中継用巻回体とを連動揺動させる連動機構が設けられている。
また、第1中継用巻回体を、第2搬送用巻回体及び第2中継用巻回体が揺動する方向にこれら第2搬送用巻回体及び第2中継用巻回体の揺動量に対して所望の揺動量だけ多く縦軸心周りに揺動させることで、第2搬送用巻回体及び第2中継用巻回体を縦軸心周りに揺動させることで生じた無端ベルトにおける搬送部分の伸縮を吸収して、ベルト幅方向での各位置での巻回経路長の変化を抑制できる。特に、第1中継用巻回体の揺動量を、第2搬送用巻回体及び第2中継用巻回体の揺動量の2倍に設定することで、ベルト幅方向での各位置での巻回経路長の変化を適切に抑制できる。
従って、下流側に設けられた下流コンベヤの搬送方向が自身の搬送方向とは異なる場合でも対応できながら横幅方向にコンパクトに構成できる搬送コンベヤを提供することができるに至った。
前記搬送コンベヤに対して前記第二方向側に隣接する隣接コンベヤが設けられ、前記連動機構が、前記隣接コンベヤと前記第2搬送用巻回体及び前記第2中継用巻回体とを前記縦軸心周りに一体的に揺動させるべく、前記隣接コンベヤと前記第2搬送用巻回体と前記第2中継用巻回体とを連動揺動させるように構成されている点にある。
そして、隣接コンベヤが縦軸心周りに揺動することで、例えば、隣接コンベヤの第二方向側(搬送方向における搬送コンベヤとは反対側)に一対の下流コンベヤを横幅方向に並ぶ状態で複数設けた場合に、それら一対の下流コンベヤの夫々に対して物品を受け渡すことができる。
また、隣接コンベヤは、搬送コンベヤのような複数の巻回体のうちの一部の巻回体を揺動させるような特殊なコンベヤに構成する必要がないため、搬送コンベヤにおける第1中継用巻回体や第2中継用巻回体に相当するものを備える必要がなく、これにより隣接コンベヤの上下方向での幅を搬送コンベヤよりコンパクトで且つ軽量に構成し易い。また、隣接コンベヤの上下方向での幅を搬送コンベヤよりコンパクトに構成することで、隣接コンベヤの下方に連動機構を配置することができ、搬送ユニット全体での平面視での大きさをコンパクトに構成することができる。さらに、第2搬送用巻回体、第1中継用巻回体、第2中継用巻回体及び隣接コンベヤの前記縦軸心周りでの回転方向が、すべて同じ方向となるため、これらを揺動操作する構成の簡素化を図り易くなる。
また、上下方向での幅がコンパクトに構成されている隣接コンベヤの下方空間を利用して第1連動部材及び第3連動部材を設けることで、これら第1連動部材及び第3連動部材を搬送コンベヤや隣接コンベヤの横側方に設ける場合に比べて、搬送ユニットを平面視でコンパクトに構成することができる。
そして、第1連動部材と第3連動部材とを移動させて、第1連結箇所及び第2連結箇所を縦軸心周りに同じ方向で且つ直線距離で同じ距離移動させることで、第2支持枠及び隣接コンベヤが揺動する方向にこれら第2支持枠及び隣接コンベヤに対して所望の揺動量だけ多く第1支持枠を縦軸心周りに揺動させることができる。
このように、第2支持枠及び隣接コンベヤが揺動する方向にこれら第2支持枠及び隣接コンベヤの揺動量より多く(例えば当該揺動量の2倍だけ)第1支持枠を縦軸心周りに揺動させるときに、第1連動部材により移動させる第1連結箇所の揺動方向及び移動距離と、第3連動部材により移動させる第2連結箇所の揺動方向と移動距離とが同じであるため、これら第1連動部材及び第3連動部材を備えた連動機構を設計し易くなる。
ちなみに、上述の如く、第1連結箇所及び第2連結箇所を直線距離(弦長)で同じ距離移動させて、第1支持枠をθ1、第2支持枠及び隣接コンベヤをθ2で揺動させる場合、縦軸心から第1連結箇所までの距離である第1揺動半径r1と、縦軸心から第2連結箇所までの距離である第2揺動半径r2との関係は、
2・r1・sin(θ1/2)=2・r2・sin(θ2/2)
となる。なお、角度の単位はラジアンである。

尚、本実施形態では、分岐用下流コンベヤ3bの搬送方向(分岐方向)は、上流コンベヤ2及び直進用下流コンベヤ3aの搬送方向(直進方向)に対して、平面視で反時計回りに30°傾いている。また、直進方向に対して直交する水平方向を横幅方向と称して説明する場合がある。
図3~図5に示すように、受入コンベヤ5には、複数の巻回体としての回転体8~11(第1搬送用回転体8、第2搬送用回転体9、第1中継用回転体10、第2中継用回転体11)と駆動用回転体12とテンション用回転体13とに亘って巻回された無端ベルトとしての受入用無端ベルト14と、駆動用回転体12を回転駆動させる搬送用駆動装置としての受入搬送用モータ15と、が設けられている。そして、受入コンベヤ5は、駆動用回転体12が受入搬送用モータ15にて回転駆動されて受入用無端ベルト14がその長手方向に移動することで、受入用無端ベルト14における上方を向く搬送面に載置された物品を搬送方向(直進方向)に沿って搬送するように構成されている。
また、第1中継用回転体10は、第1搬送用回転体8及び第2搬送用回転体9より下方に位置し且つ搬送方向において第1搬送用回転体8と第2搬送用回転体9との間に位置するように設けられている。第2中継用回転体11は、第1搬送用回転体8及び第2搬送用回転体9より下方に位置し且つ第1中継用回転体10より搬送下流側に位置するように設けられている。本実施形態では、第2中継用回転体11は、第2搬送用回転体9の直下(平面視で同じ位置)に位置している。駆動用回転体12は、搬送方向において第1搬送用回転体8と第1中継用回転体10との間に設けられている。テンション用回転体13は、搬送方向において駆動用回転体12より搬送上流側に位置するように設けられており、具体的には、搬送方向において第1搬送用回転体8と駆動用回転体12との間に設けられている。
また、第1搬送用回転体8と第2搬送用回転体9とは同じ高さに位置し、第1中継用回転体10と駆動用回転体12とは同じ高さに位置し、第2中継用回転体11とテンション用回転体13とは同じ高さに位置している。
このようにして、第2搬送用回転体9、第1中継用回転体10及び第2中継用回転体11が、受入コンベヤ5における搬送方向の下流側端部に位置する第1軸心X1周りに揺動自在に支持されている。
ちなみに、第1軸心X1は、平面視において受入用無端ベルト14の横幅方向の中央に位置し且つ第2搬送用回転体9より搬送方向下流側に位置しており、第1軸心X1と第2搬送用回転体9とは、第2搬送用回転体9の直径より短い半径程度だけ搬送方向にずれている。
スイングコンベヤ6には、上流側回転体22、下流側回転体23、駆動回転体24、テンション回転体25、これらの回転体22~25に巻回されたスイング用無端ベルト26、及び、スイング搬送用モータ27が設けられている。そして、スイング搬送用モータ27にて駆動回転体24が回転駆動されることで、スイング用無端ベルト26の搬送面を形成する部分が搬送方向に移動するように構成されている。また、搬送面が水平となる状態でスイングコンベヤ6が設置され且つ分岐コンベヤ1が直進状態に切り換えられている状態では、上流側回転体22、下流側回転体23、駆動回転体24、テンション回転体25の夫々は、回転軸心が横幅方向に沿っており、これらの回転体22~25の回転軸心方向が互いに平行となる状態となっている。
ちなみに、スイングコンベヤ6は、分岐コンベヤ1が分岐状態に切り換えられたときに、スイングコンベヤ6の搬送下流側の端部が直進状態での分岐コンベヤ1のスイング用無端ベルト26の横幅内から横側方に外れる長さに構成されている。
図4及び図5に示すように、分岐コンベヤ1(受入コンベヤ5)には、第1支持枠18と第2支持枠19と枠体28とを連動させる連動機構33(図3参照)が設けられている。
この連動機構33は、第2支持枠19及び枠体28が第1軸心X1周りに揺動するに伴って第1支持枠18を第1軸心X1周りに第2支持枠19の揺動方向と同じ方向で且つ第2支持枠19が揺動する揺動量より多く(本実施形態では2倍)揺動させるべく、第1支持枠18と第2支持枠19と枠体28とを連動させている。
連動機構33には、揺動用駆動装置としての揺動用モータ34にて上下方向に沿う第2軸心X2周りに回転駆動される連結部材38と、基端部が連結部材38に連結され且つ先端部が第1支持枠18に連結された第1リンク体35と、基端部が連結部材38に連結され且つ先端部が枠体28に連結された第2リンク体36と、を備えて構成されている。尚、第1中継用回転体10を揺動用モータ34に連動させる第1連動部材aは、第1リンク体35と第1支持枠18とで構成されており、スイングコンベヤ6を揺動用モータ34に連動させる第3連動部材cは、第2リンク体36にて構成されている。また、第2搬送用回転体9及び第2中継用回転体11を揺動用モータ34に連動させる第2連動部材bは、第2リンク体36と枠体28(スイングコンベヤ6)と第2支持枠19とで構成されている。
ちなみに、図4及び図5で示すように、第1連結箇所P1及び第2連結箇所P2を直線距離(弦長)で同じ距離移動させて、第1支持枠18を60°、第2支持枠19及び枠体28を30°揺動させる場合では、第1軸心X1から第1連結箇所P1の平面視での直線距離(第1揺動半径r1)と、第1軸心X1から第2連結箇所P2の平面視での直線距離(第2揺動半径r2)との関係は、
2・r1・sin(60/2)=2・r2・sin(30/2)
となる。なお、角度の単位(上記の式中の“60”や“30”の単位)は度である。
第1揺動半径r1と第2揺動半径r2とをこのような関係とすることで、第1連結箇所P1及び第2連結箇所P2を直線距離で同じ距離移動させながら、第1支持枠18の揺動量を第2支持枠19及び枠体28の揺動量の2倍とすることができ、分岐コンベヤ1の姿勢を切り換えたときの、ベルト幅方向での各位置での巻回経路長の変化を抑制することができる。
また、図4及び図5に示すように、第1リンク体35は、第2リンク体36より長く形成されている。
また、揺動用モータ34及び連結部材38は、受入用無端ベルト14やスイング用無端ベルト26に対して横幅方向の他方側(分岐用下流コンベヤ3bが位置する側)に位置している。
また、第1連結箇所P1は、第1軸心X1よりも搬送下流側に位置しており、第2連結箇所P2は、第1連結箇所P1よりもさらに搬送下流側に位置している。そして、搬送方向において第1連結箇所P1と第2連結箇所P2との間に少なくとも一部が位置するように、揺動用モータ34及び連結部材38が設けられている。
また、図3に示すように、第1リンク体35及び第2リンク体36は、上下方向において基台20と枠体28との間に位置しており、枠体28(スイングコンベヤ6)の下方に配設されている。そして、第1リンク体35、第2リンク体36及び枠体28は、受入コンベヤ5の上下幅内(受入用無端ベルト14の上下方向での巻回幅内)に配設されている。
同様に、分岐コンベヤ1を直進状態に切り換えたときの第2連結箇所P2、分岐コンベヤ1を分岐状態に切り換えたときの第2連結箇所P2、分岐コンベヤ1を直進状態に切り換えたときの第4連結箇所P4、分岐コンベヤ1を分岐状態に切り換えたときの第4連結箇所P4、及び第2軸心X2が、平面視で一直線上に並ぶようになっている。また、直進状態と分岐状態との中間の状態(直進状態から枠体28を反時計回りに15°揺動させた状態)において、第1軸心X1と第2連結箇所P2とを結ぶ線分と第2連結箇所P2と第4連結箇所P4とを結ぶ線分とが平面視で直交するようになっている。
そして、連動機構33は、第1軸心X1の位置、第2軸心X2の位置、第1リンク体35の連結部材38や第1支持枠18との連結位置、及び第2リンク体36の連結部材38や枠体28との連結位置等の関係から、揺動用モータ34の駆動により連結部材38を第2軸心X2周りに揺動させて第1リンク体35及び第2リンク体36を動かすことで、第1連結箇所P1及び第2連結箇所P2を第1軸心X1周りに同じ方向で且つ直線距離で同じ距離移動させて、第2支持枠19及び枠体28が揺動する方向に第2支持枠19及び枠体28の揺動量の2倍だけ第1支持枠18を第1軸心X1周りに揺動させるように構成されている。
具体的には、連動機構33は、図4に示す状態から図5に示す状態に、連結部材38が180°回転することで、第1連結箇所P1及び第2連結箇所P2を第1軸心X1周りに反時計回りに弦長が同じ距離となるように移動させて、枠体28(スイングコンベヤ6)及びこれに連結されている第2支持枠19(第2搬送用回転体9及び第2中継用回転体11)を反時計回りに30°揺動させるとともに、第1支持枠18(第1中継用回転体10)を反時計回りに60°揺動させるように構成されている。
この蛇行防止機構41は、受入用無端ベルト14の横幅方向の両端部の夫々に対して設けられており、このように設けられた一対の蛇行防止機構41は、受入用無端ベルト14の長手方向に沿って複数組設けられている。尚、搬送部分14aの搬送下流側端部に対して設けられている蛇行防止機構41については、一対の蛇行防止機構41のうちの横幅方向の一方側(分岐用下流コンベヤ3bが位置する側とは反対側)の蛇行防止機構41のみが設けられており、受入コンベヤ5を分岐状態に切り換えたときに第1支持枠18と蛇行防止機構41とが干渉しないようになっている。
連動機構33により、第2搬送用回転体9と第2中継用回転体11とを第1軸心X1周りに一体的に揺動させ且つ第2搬送用回転体9及び第2中継用回転体11が揺動する方向に第2搬送用回転体9及び第2中継用回転体11の揺動量の2倍だけ第1中継用回転体10を第1軸心X1周りに揺動させるべく、第2搬送用回転体9と第1中継用回転体10と第2中継用回転体11とが連動揺動されている。
そして、第1軸心X1が、第2搬送用回転体9が設けられている搬送方向の下流側端部に位置しているため、第2搬送用回転体9の揺動半径が小さくなり、第2搬送用回転体9を小さなスペースで揺動させることができる。
(1)上記実施形態では、上流コンベヤ2と下流コンベヤ3との間に、分岐コンベヤ1を1台設けたが、上流コンベヤ2と下流コンベヤ3との間に、これらの上流コンベヤ2及び下流コンベヤ3の台数に応じて分岐コンベヤ1を複数台設けてもよい。
つまり、例えば、図7及び8に示すように、上流コンベヤ2を1台設け、下流コンベヤ3を2台設ける場合では、上流コンベヤ2の搬送下流側に隣接する状態で第1の分岐コンベヤ1を設け、直進用下流コンベヤ3aの搬送上流側に隣接する状態で第2の分岐コンベヤ1を設け、分岐用下流コンベヤ3bの搬送下流側に隣接する状態で第3の分岐コンベヤ1を設けてもよい。
ちなみに、第1~第3の分岐コンベヤ1は、スイングコンベヤ6の搬送方向での長さが短い以外は、上記実施形態の分岐コンベヤ1と同様に構成されている。
このように搬送設備を構成することで、スイングコンベヤ6の搬送方向での長さを短くすることができる。
つまり、連動機構33を次のように構成してもよい。
図9~図11に示すように、枠体28に、この枠体28と第1軸心X1周りに一体回転する扇形ギヤ45を設け、第1支持枠18に、ギヤ部分46を形成する。そして、扇形ギヤ45に噛合する小径ギヤ47と、この小径ギヤ47より大径で且つギヤ部分46に噛合する大径ギヤ48とを、一体回転する状態で設ける。
このような扇形ギヤ45、ギヤ部分46、小径ギヤ47、及び大径ギヤ48を備えて連動機構33を構成し、作業者が手作業でスイングコンベヤ6を第1軸心X1周りに回転操作することで、小径ギヤ47及び大径ギヤ48が回転して、第1支持枠18が、スイングコンベヤ6を揺動させた方向と同じ方向に揺動するとともに、スイングコンベヤ6が揺動した揺動量の倍の揺動量だけ揺動するように構成されている。また、第2支持枠19は、スイングコンベヤ6を揺動させた方向と同じ方向にスイングコンベヤ6の揺動量と同じ量だけ揺動する。
つまり、図14に示すように、図外の揺動用モータ34にて第2軸心X2周りに回転駆動される出力ギヤ51に反転用中継ギヤ52を咬合させ、反転用中継ギヤ52に第1揺動用回転ギヤ53を噛合させ、出力ギヤ51に第2揺動用回転ギヤ54を噛合させる。そして、第1リンク体35の基端部を第1揺動用回転ギヤ53に連結し、第2リンク体36の基端部を第2揺動用回転ギヤ54に連結させて、連動機構33を構成してもよい。
図14(a)に示すように分岐コンベヤ1を直進状態に切り換えた状態から、揺動用モータ34にて出力ギヤ51及び反転用中継ギヤ52を所定量だけ回転駆動させることで、第1揺動用回転ギヤ53が反時計回りに回転し、第2揺動用回転ギヤ54が時計回りに回転する。これにより、連動機構33は、第1リンク体35及び第2リンク体36が移動して、第1連結箇所P1及び第2連結箇所P2が第1軸心X1周りに反時計回りに弦長が同じ距離となるように移動し、枠体28(スイングコンベヤ6)及びこれに連結されている第2支持枠19(第2搬送用回転体9及び第2中継用回転体11)を反時計回りに30°揺動させるとともに、第1支持枠18(第1中継用回転体10)を反時計回りに60°揺動させて、図14(b)に示すように分岐コンベヤ1を分岐状態に切り換えるように構成されている。
また、上記実施形態では、揺動用駆動装置を設けて、揺動用駆動装置の駆動力により、第1支持枠18及び第2支持枠19を揺動させたが、作業者の手作業により、これら第1支持枠18及び第2支持枠19を揺動させてもよい。
具体例を挙げると、上記した別実施形態(2)において、シリンダ等の揺動用駆動装置にてスイングコンベヤ6を第1軸心X1周りに揺動させることで、連動機構33にて連動連結された第1支持枠18及び第2支持枠19を揺動させてもよく、また、作業者の手作業でスイングコンベヤ6を第1軸心X1周りに揺動させることで、連動機構33にて連動連結された第1支持枠18及び第2支持枠19を揺動させてもよい。
具体的には、例えば、下流コンベヤ3として分岐用下流コンベヤ3bのみを設けて、分岐コンベヤ1を分岐状態に切り換えた状態で設置してもよく、また、下流コンベヤ3として直進用下流コンベヤ3aのみ設けて、分岐コンベヤ1を直進状態に切り換えた状態で設置してもよい。
また、上記実施形態では、分岐コンベヤ1を直進状態に切り換えられている状態から第2支持枠19を一方側に揺動(反時計回りに揺動)させて分岐状態に切り換えたが、この分岐状態に加えて又は代えて、分岐コンベヤ1を直進状態に切り換えられている状態から第2支持枠19を他方側に揺動(時計回りに揺動)させて分岐状態に切り換えるようにしてもよい。
また、受入用無端ベルト14が横幅方向の一方側のみに受入用無端ベルト14の蛇行が想定される場合は、受入用無端ベルト14の横幅方向における蛇行が想定される方向とは反対側の端部に対してのみ蛇行防止機構41を設けてもよい。ちなみに、例えば、受入コンベヤ5を次のように構成することで受入用無端ベルト14の蛇行を一方側のみに設定することが考えられる。すなわち、分岐コンベヤ1を直進状態に切り換えた状態において、受入コンベヤ5に設けられている巻回体の一部(例えば、第1中継用回転体10)の姿勢を、他の巻回体に対して上下軸心又は左右軸心周りに傾けた姿勢とすることで、蛇行の方向を設定することが考えられる。
