Abstract
Description
しかしながら、特許文献2の物品搬送設備では、車輪が第1連結部より後方に位置している。そのため、図13に示すように、走行経路に水平部分r1と傾斜部分r2とがある場合において、例えば、搬送台車が傾斜部分r2と水平部分r1との接続部を通過するときに、搬送台車1aの第1連結部10aは、水平部分r1を走行するときの位置(図13にて仮想線で示す位置)よりも一旦低くなる(図13にて実線で示す位置)ため、搬送台車が安定よく走行できないという不具合がある。
前記車輪が、前記台車本体の前端部に設けられ、前記車輪と前記第1連結部の前記台車揺動軸心とが、台車横幅方向視で重複する。
また、第1連結部の台車揺動軸心は、台車横幅方向視で車輪と重複しており、例えば、走行経路に水平部分と傾斜部分とがある場合において、台車本体が水平部分と傾斜部分との接続部を通過するときに、車輪が接続部を通過するタイミングと第1連結部の台車揺動軸心が接続部を通過するタイミングとを近づけることができるため、第1連結部が走行面に対して上下動し難くなり、搬送台車を安定よく走行させることができる。
そして、キャスター枠に支持された車輪は、直進走行状態では車輪揺動軸心より後方に車輪回転軸心が位置するが、このような車輪と台車揺動軸心とを、台車横幅方向視で重複させることで、第1連結部が走行面に対して上下動し難くなり、搬送台車を安定よく走行させることができる。
そこで、台車本体の前端部を、台車横幅方向の中央部が両端部より後方に位置する凹入形状に形成し、キャスター枠を、台車本体における台車横幅方向の両端部の夫々に設け、第1連結部を、台車本体における台車横幅方向の中央部に備えることで、車輪と第1連結部の台車揺動軸心とを、台車横幅方向視で重複させ易くできる。
そして、規制体は、揺動重複箇所と回転重複箇所とに位置を変更自在であるため、走行レールが台車横幅方向に細い等により車輪が走行レールから脱輪し易い場合は、規制体の位置を揺動重複箇所に変更し、規制体が案内レールの上端近くに位置している等により規制体が案内レールから離脱しやすい場合は、規制体の位置を回転重複箇所に変更するというように、規制体の位置を走行レールや案内レールの形状に応じた位置に変更することができる。
特に、ループ状の台車列を形成させた場合において、製作誤差や据え付け誤差等により、台車列の長さがループ状の搬送経路に応じた長さより長い場合や短い場合があるが、上述の如く台車列の長さを調節することで台車列の長さを搬送経路の長さに応じた長さにすることができる。
図1に示すように、物品搬送設備には、ループ状に形成された走行経路Rに沿って移動自在な搬送台車1を走行経路Rに沿って複数台連結した台車列Tと、搬送台車1に物品を受け渡す第1搬送部2と、搬送台車1から物品を受け取る第2搬送部3と、が設けられている。ちなみに、本実施形態では、物品は、スーツケースや旅行かばん等の大小様々な手荷物であり、物品搬送設備は、空港に設置されている。
第2搬送部3は、走行経路Rに向けて上り傾斜する傾斜面を備えたスロープ又はローラコンベヤにて構成されており、物品をその自重により図中矢印で示す方向に移動させて第2搬送部3に隣接して位置する搬送台車1から受け取った物品を図外に向けて搬送するように構成されている。
第1搬送部2及び第2搬送部3の夫々は、走行経路Rに沿って複数設けられている。
そして、物品搬送設備は、複数の第1搬送部2のいずれかにて搬送された物品を、複数の搬送台車1のいずれかに受け渡し、物品を受け取った搬送台車1は、走行経路Rに沿って移動して、複数の第2搬送部3のいずれかに物品を受け渡すように構成されている。
また、図1上で上側に位置する直線経路が図1上で下側に位置する直線経路より高い位置に設定されている。そして、搬送台車1は図1上で走行経路Rを反時計回りに走行するため、図1上で右側に位置する曲線傾斜部分R2は上り傾斜、図1上で左側に位置する曲線傾斜部分R2は下り傾斜となっている。
ちなみに、搬送台車1の走行方向に沿う方向を台車前後方向Xとし、その台車前後方向Xと直交する水平方向を台車横幅方向Yとして説明する。尚、搬送台車1の台車前後方向Xの前端部や台車前後方向Xの後端部の夫々を単に前端部や後端部と称する場合や、搬送台車1の台車横幅方向Yの両端部や台車横幅方向Yの中央部の夫々を単に両端部や中央部と称する場合がある等、台車前後方向Xや台車横幅方向Yを省略して説明する場合がある。
図3に示すように、載置台7は、姿勢切換用モータ12の駆動により、支持用姿勢(実線で示す姿勢)と、支持用姿勢から台車前後方向Xに沿う軸心周りに揺動させた受渡用姿勢(仮想線で示す姿勢)と、に切換自在に構成されている。支持用姿勢は、載置台7上に物品を保持できる姿勢であり、搬送台車1は、載置台7を支持用姿勢とした状態で第1搬送部2から物品を受け取るようになっている。また、受渡用姿勢は、物品の自重により載置台7上で台車横幅方向Yに移動するように傾けた姿勢であり、搬送台車1は、載置台7を受渡用姿勢に切り換えて載置台7上の物品を第2搬送部3に受け渡すようになっている。
図4に示すように、台車本体6は、台車横幅方向Yに沿う姿勢の横枠14と、台車前後方向Xに沿う姿勢の前後枠15と、を備えて構成されている。すなわち、横枠14は、台車横幅方向Yに延びるように形成され、前後枠15は、台車前後方向Xに延びるように形成されている。横枠14は、台車本体6における台車前後方向Xの前端部に備えられており、その横枠14の台車横幅方向Yの中央部と前後枠15の台車前後方向Xの前端部とが連結されている。つまり、台車本体6は、横枠14と前後枠15とで平面視形状がT字状に形成されている。
このように横枠14を形成することで、台車本体6の前端部は、台車横幅方向Yの中央部が両端部より後方に位置する凹入形状に形成されている。
図5及び図6に示すように、搬送台車1には、台車前後方向Xに並ぶ状態で複数個の磁石(永久磁石)17が設けられており、地上側には、リニアモータ18が設けられている。台車列Tを走行経路Rに沿って移動させる駆動装置4は、これら複数個の磁石17とリニアモータ18とで構成されている。ちなみに、リニアモータ18として、リニア同期モータが設けられている。
そして、図6に示すように、複数個の磁石17は、一列に並べた状態で長尺状のタッププレート19に固着されており、そのタッププレート19を台車前後方向Xに沿う姿勢で台車本体6の下面部に取り付けることで、台車本体6の下方に台車前後方向Xに一列に並ぶ状態で取り付けられている。
プレート用蟻溝20aは、下方に開口する状態で台車本体6に形成されている。連結具用蟻溝20bは、プレート用蟻溝20aの上側に形成されており、プレート用蟻溝20aと連通する状態で台車本体6に形成されている。
そして、プレート用蟻溝20aにタッププレート19を挿入し、連結具用蟻溝20bに挿入した連結具21を用いてタッププレート19を台車本体6に固定するようになっている。
搬送台車1は、前側に隣接する別の搬送台車1、及び、後側に隣接する別の搬送台車1とは、連結ユニット24にて連結されている。この連結ユニット24は、搬送台車1の前端部に連結する第1連結部10と、搬送台車1の後端部に連結する第2連結部11と、で構成されている。
つまり、自車の前端部に連結ユニット24の第1連結部10を連結し、且つ、前側に隣接する別の搬送台車1の後端部に連結ユニット24の第2連結部11を連結することで、自車を前側に隣接する別の搬送台車1と連結するようになっている。また、自車の後端部に連結ユニット24の第2連結部11を連結し、且つ、後側に隣接する別の搬送台車1の前端部に連結ユニット24の第1連結部10を連結することで、自車を後側に隣接する別の搬送台車1と連結するようになっている。
また、第2連結部11は、台車本体6における台車横幅方向Yの中央部で且つ台車前後方向Xの後端部に備えられており、前後枠15における後面に連結されている。
説明を加えると、連結ユニット24の第1連結部10には、ボルトやナット等を用いて台車本体6の前端部に連結するときに用いる連結孔(図示せず)が形成されている。この連結孔は、第1台車揺動軸心P1に対して台車前後方向Xにずれた位置に形成されている。具体的には、第1台車揺動軸心P1に対して、連結孔の中心が台車前後方向Xに0.5mmずれている。
搬送台車1は、搬送台車1が水平姿勢である状態(直線水平部分R1に位置している状態)において上下方向に沿う車輪揺動軸心P3周りに回転自在に、台車本体6に連結されたキャスター枠25を備えている。そして、キャスター枠25が、車輪8の回転軸心である車輪回転軸心P4が車輪揺動軸心P3に対して水平方向に異なる位置となる状態で車輪8を回転自在に支持している。このように、車輪8の車輪回転軸心P4が車輪揺動軸心P3に対して水平方向に異なる位置としているため、搬送台車1の平面視での走行方向が直線水平部分R1と曲線傾斜部分R2とで変わるに伴って、車輪8の向きが変更されるようになっている。
このようにキャスター枠25及び車輪8は台車本体6に一対設けられており、車輪8が転動する走行レール26も、一対の車輪8に対応して一対設けられている。一対の走行レール26の夫々は、走行経路Rに沿って設けられており、走行レール26の上面にて、車輪8が転動する走行面26aが形成されている。
搬送台車1には、走行レール26に接触して搬送台車1の台車横幅方向Yへの移動を規制する規制体9が設けられている。
この規制体9は、上下方向に沿う規制回転軸心P5周りに回転自在な回転体にて構成されており、走行レール26における台車横幅方向Yの内側の面に接触する状態で設けられている。なお、走行レール26は、走行経路Rに沿って設けられた案内レールに相当する。
規制体9は、上下方向に沿う規制体回転軸心P5周りに回転自在に設けられている。
また、図10に示すように、規制体9を回転重複箇所に取り付けることで、搬送台車1が直線水平部分R1と曲線傾斜部分R2との接続部を走行するときに、車輪8が接続部を通過するタイミングと規制体9が接続部を通過するタイミングとを合わせることができるため、規制体9が走行面26aに対して上下動し難くなり、規制体9が走行レール26から上下方向に離脱し難くなる。
(1)上記実施形態では、車輪回転軸心P4の延長線上に第1台車揺動軸心P1が位置するようにして、第1台車揺動軸心P1と車輪8とを、台車横幅方向視で重複させたが、車輪回転軸心P4を第1台車揺動軸心P1より台車前後方向Xで後方側に位置させながら、第1台車揺動軸心P1と車輪8とを、台車横幅方向視で重複させてもよく、また、車輪回転軸心P4を第1台車揺動軸心P1より台車前後方向Xで前方側に位置させながら、第1台車揺動軸心P1と車輪8とを、台車横幅方向視で重複させてもよい。
つまり、車輪8は、第1台車揺動軸心P1と台車横幅方向視で重複するように設ければよく、具体的には、車輪8の半径を50mmと仮定すれば、車輪回転軸心P4と第1台車揺動軸心P1との台車前後方向Xでのずれ量は50mm以下に抑えればよい。また、台車列Tにおける台車前後方向Xでの車輪8のピッチ(本例では1200mm)を考慮すれば、車輪回転軸心P4と第1台車揺動軸心P1との台車前後方向Xでのずれ量は20mm以下に抑えることが望ましい。
この場合、第1連結部10を後方寄りに設けることで、車輪8と第1台車揺動軸心P1とを台車横幅方向視で重複させてもよく、また、車輪8を前方寄りに設けることで、車輪8と第1台車揺動軸心P1とを台車横幅方向視で重複させてもよい。
また、上記実施形態では、走行経路Rを直線部分と曲線部分とを組み合わせて構成したが、走行経路Rをループ状とした場合には曲線部分のみにて構成してもよく、走行経路Rを有端状とした場合には直線部分のみにて構成してもよい。
要するに、上記実施形態では、直線水平部分R1と曲線傾斜部分R2とを組み合わせて走行経路Rを形成したが、直線水平部分R1、曲線傾斜部分R2、搬送台車1の走行方向に水平で且つ平面視で曲線に設定された曲線水平部分、及び、搬送台車1の走行方向に傾斜し且つ平面視で直線に設定された直線傾斜部分、を適宜組み合わせて走行経路Rを形成してもよい。
また、上記実施形態では、走行レール26の側面に規制体9を接触させるようにして、走行レール26を案内レールに兼用させたが、走行レール26とは別に案内レールを設けてもよい。
また、上記実施形態では、第1連結部10の台車本体6の前端部に対する連結位置の調整量を1mmとしたが、この調整量は、例えば、0.1mm~10mmの範囲内で適宜設定すればよく、第1連結部10の連結位置を調整することで、前記車輪と前記台車揺動軸心とが台車横幅方向視で重複する範囲から外れない調整量であればよい。
