Description

以下に、上記した実施の形態における作用を説明する。
【００４５】
図１の仮想線、図９に示されるように、一定経路５中で乾燥炉９の部分を除いた所定経路部分では、受動面２５に当接している送りローラ９２をインダクションモータ９１により駆動回転させることで、摩擦式送り装置９０により移動体２０に移動力（走行力）を付与することになって、この移動体２０を送り移動し得る。すなわち、摩擦式送り装置９０による移動体２０の移動は、その送りローラ９２を、端部被案内装置５０の受動面２５、前部フレーム体２２の受動面２５、中間部フレーム体２３の受動面２５、後部フレーム体２４の受動面２５、ならびに端部被案内装置５０の受動面２５へと順次作用させることで行われる。
【００４６】
その際に、送りローラ９２が前部フレーム体２２側に作用しているとき、中間部フレーム体２３や後部フレーム体２４などは縦方向軸体２７を介して引っ張り移動され、また中間部フレーム体２３に作用しているとき、前部フレーム体２２側は縦方向軸体２７を介して押し移動されるとともに後部フレーム体２４側は縦方向軸体２７を介して引っ張り移動され、さらに後部フレーム体２４側に作用しているとき、中間部フレーム体２３と前部フレーム体２２側は縦方向軸体２７を介して押し移動されることになる。
【００４７】
このような移動（走行）の際に各被案内装置３０，５０は、各被支持ローラ３３，５３を介してレール装置１１の両レール１２に支持案内され、そして各被ガイドローラ３５，５５がガイド部１２ａに当接して案内される。その際に、中間部被案内装置３０のトロリ本体３１が、縦方向軸体２７の下位軸部２７ｄに連結したブラケット４０の下位二股部４０ａに、左右方向軸４１を介して相対回動自在に連結されていることで、その連結部分にガタが発生し難い構成となる。
【００４８】
したがって、たとえ被搬送物Ｗとして大形（幅広や背高）で偏荷重のものを搬送するときでも、支持部６０、すなわち被搬送物Ｗの傾きを減少（小さく）し得、搬送を安定して行えるとともに、被搬送物Ｗに対する各種作業や被搬送物Ｗの積み降ろしは、常に正確に行える。しかも、下位二股部４０ａにトロリ本体３１を嵌合させる中間部被案内装置３０は小形かつ安価となり、以て全体を安価に構成し得る。
【００４９】
上述した移動体２０の移動は、摩擦式送り装置９０の配設ピッチＰの置きに間欠的に行われ、その際に、下手の摩擦式送り装置９０の部分が空状態のときに間欠的な送りが行われるように、適宜の検出手段などによる検出に基づいて自動制御されている。そして摩擦式送り装置９０の位置において、送りローラ９２の非回転により移動体２０を停止させるとともに適宜の位置決め手段によって位置決めを行った状態で、床１上の作業者や本体２１上に乗り移った作業者が、支持部６０に支持されている被搬送物Ｗに対して各種の作業を遂行する。
【００５０】
前記移動体２０の移動は、左右方向でのカーブ経路部５ｂでも同様にして行われる。その際にカーブ経路部５ｂでは、図１０に示されるように、各フレーム体２２，２３，２４は縦方向軸体２７を介して左右方向で相対的に屈折した姿勢で移動される。さらに端部被案内装置５０は、縦方向ピン５８を介して前後のフレーム体２２，２４に対して左右方向で相対的に屈折した姿勢で移動されることになる。
【００５１】
このようなカーブ経路部５ｂでの移動時において中間部被案内装置３０は、図１０に示されるように、各被支持ローラ３３を介してレール装置１１の両レール１２に支持案内され、そして各被ガイドローラ３５がガイド部１２ａに当接して案内されることにより、本体２１側に対して縦方向軸体２７とともに回動する。これにより中間部被案内装置３０は、レール１２に対して引っ掛かることなく、ガタ付くことなく支持案内されることになり、以てカーブ経路部５ｂにおける移動体２０の移動を常に円滑に行えることになる。
【００５２】
このとき図１０の仮想線に示されるように、縦方向軸体２７に連結されたローラ支持体６８も一体に回動することになって、遊転輪６６を支持する軸６９の軸心をカーブ半径方向に沿った（合致させた）方向とし得、以て遊転輪６６を、スリップ（摩擦抵抗）を伴うことなく円滑に回転し得る。したがってローラ支持体６８は、ガイドレール６に対して引っ掛かることなく、ガタ付くことなく支持案内されることになり、以て被搬送物Ｗを支持している移動体２０のカーブ経路部５ｂにおける移動を、常に安定して円滑に行えることになる。
【００５３】
さらにカーブ経路部５ｂにおけるガイドレール６の構成、配置（取り合い）を直線状経路部５ａと同様にし得、以てカーブ経路部５ｂにおけるガイドレール６を簡単かつ安価に配設し得る。
【００５４】
なお、ガイドレール６の据え付け精度などによって、このガイドレール６とレール装置１１との上下間隔に変化が生じたとき、上位軸部２７ａに対して筒部材６７が昇降することで、その差を吸収し得、以て常に安定した支持案内を行える。
【００５５】
またカーブ経路部５ｂでの移動時において、端部被案内装置５０は、前後一対の被ガイドローラ５５がガイド部１２ａに案内されることで、前後のフレーム体２２，２４の長さ方向に対して縦方向ピン５８の回りに相対回転している。その際に、前後の被ガイドローラ５５間の１箇所に設けられている左右一対の被支持ローラ５３は、前後の被ガイドローラ５５を取り付けた縦方向ピン５４の軸心間を結ぶ線に対して平行状に向いており、すなわち、フレーム体２２，２４の移動方向に対して傾斜した方向に向いており、したがって被支持ローラ５３は、スリップ（摩擦抵抗）を伴いながらの摩擦回転となる。
【００５６】
しかし、摩擦回転は前後の１箇所でかつ左右一対の合計２箇所であることによって、さほど影響のないものとなり、したがって端部被案内装置５０は、レール１２に対して引っ掛かることなく、ガタ付くことなく支持案内されることになり、以てカーブ経路部５ｂにおける移動体２０の移動を常に円滑に行えることになる。
【００５７】
このようにして、カーブ経路部５ｂを移動した移動体２０は乾燥炉９の入口部に達し、その受動体３６を無端回動式送り装置７０の作用経路に突入させて停止させる。ここで乾燥炉９の部分では無端回動式送り装置７０が作動されている。
【００５８】
すなわち、駆動装置７３により各歯輪７１，７２を介してチェーン７４が移動されている。そして、チェーン７４と一体移動される伝動体８２は、作用経路の始端部分から受動体３６に向って移動し、まず惰走防止体３８のカム面３８ｄに当接して、この惰走防止体３８を、図８の仮想線に示すように横ピン３９の周りに上方へ揺動させ、以て伝動体８２は惰走防止体３８の部分を通過する。そして伝動体８２は、図５に示すように受動体３６の受動面３６ａに当接し、これにより移動体２０を一体状に移動させる。
【００５９】
このようにして移動体２０を乾燥炉９内で移動させながら、支持部６０で支持している被搬送物Ｗに対して、乾燥手段（図示せず。）により乾燥作業を遂行する。その際に無端回動式送り装置７０は、乾燥炉９内でチェーン７４のみが移動することから、熱などに強い送り構成とし得、以て長期に亘っての安定した動作を期待し得る。なお、伝動体８２を受動体３６の受動面３６ａに当接させての移動体２０の移動中に、この移動体２０が惰走（暴走）しようとしたとき、惰走防止体３８の惰走防止面３８ａが伝動体８２に当接して、その惰走を防止し得る。
【００６０】
移動体２０が乾燥炉９の出口部分に達すると、たとえばチェーンガイド装置１４のレール１５を下降傾斜状に形成することにより、受動体３６に対して伝動体８２が下降動し、以て受動体３６に対する伝動体８２の係合が外れる。これにより、無端回動式送り装置７０による送り力が開放され、それ以降は、前述した摩擦式送り装置９０により移動力が付与される。
【００６１】
なお、乾燥炉９の部分から出たのち適宜の箇所において、作業済みの被搬送物Ｗが支持部６０から降ろされるとともに、支持部６０に新たな被搬送物Ｗが積み込まれる。このようにして移動体２０は、一定経路５上において、循環移動される。
【００６２】
このような循環移動において、被搬送物Ｗや支持部６０の荷重の全ては、前後の縦方向軸体２７を介して両中間部被案内装置３０に直接に伝達され、そしてトロリ本体３１に前後に振り分けて設けられた被支持ローラ３３を介してレール装置１１側に支持されることになり、以て移動体２０の移動は、荷重の有無、荷重の大小に関係なく、常に安定して行える。
【００６３】
さらに一定経路５中に、側面視における上下方向への昇降経路部５ｃが形成されている場合、まず、前の端部被案内装置５０が円弧部から傾斜部へと移動する際には、図１２（ａ）に示されるように、前部フレーム体２２が左右方向ピン２２Ｄを介して上方向に屈曲動される。次いで、前の中間部被案内装置３０が円弧部から傾斜部へと移動する際には、図１２（ｂ）に示されるように、縦方向軸体２７側のブラケット４０に対して前後の中間部被案内装置３０が、それぞれ左右方向軸４１の周りに相対回動される。そして、後の端部被案内装置５０が円弧部から傾斜部へと移動する際には、図１２（ｃ）に示されるように、後部フレーム体２４が左右方向ピン２４Ｄを介して上方向に屈曲動される。
【００６４】
これにより移動体２０は、昇降経路部５ｃにおけるレール１２の傾斜に応じて、端部被案内装置５０や中間部被案内装置３０の向き（上下角度）を自動的に変更しながら昇降経路部５ｃに入り込み、そして図１１に示されるように、昇降経路部５ｃにおいて円滑に上昇移動される。なお、昇降経路部５ｃから出て行くときには、屈曲動の方向を逆として同様に移動される。また、昇降経路部５ｃが下りの場合も同様に移動される。
【００６５】
このような移動の際に、昇降経路部５ｃにおける昇降傾斜角度θを、前後の端部被案内装置５０における被支持ローラ５３間の距離Ｌαが長いほど小さくして設定したことで、上りや下りの昇降経路部５ｃにおける移動体２０の入りや出を、左右方向ピン２４Ｄや左右方向軸４１の周りに無理なく屈曲動させて常に円滑に行える。
【００６６】
上述した実施の形態において、各被案内装置３０，５０を支持案内するレール装置１１のレール１２は、その上縁部に被ガイドローラ３５，５５の案内を行うガイド部１２ａが上方へ曲げ成形されていることで、ガイド部を有するレールを容易に構成し得る。
【００６７】

【００６８】
上記した実施の形態では、直線状経路部５ａにおいて、前後端間に隙間を生じる状態で移動体２０を移動させる形式を示しているが、これは、直線状経路部５ａの上手側に前記摩擦式送り装置９０を設けるとともに、下手側に前記受動面２５に作用して移動体２０に制動力を付与する制動装置を設けた形式としたときには、摩擦式送り装置９０から制動装置の間で、複数台の移動体２０を、そのトロリ本体５１の前端をトロリ本体５１の後端に相当接させながら、前後端間に隙間を生じめることなく密な後押し状態で整列させて移動し得る。
【００６９】
上記した実施の形態では、無端回動式送り装置７０と摩擦式送り装置９０とにより移動体２０を移動させる形式を示しているが、これは、いずれか一方のみにより移動体２０を移動させる形式などであってもよい。
【００７０】
上記した実施の形態では、本体２１の一側面に受動面２５を形成し、この受動面２５に作用する摩擦式送り装置９０を設けた形式を示しているが、これは本体２１の他側面に作用される受けローラを設けて、本体２１を両側から挟みつけて強い摩擦力を得、以て充分な移動力を与え得る形式などであってもよい。
【００７１】
上記した実施の形態では、移動体２０の本体２１として、３本のフレーム体２２，２３，２４からなる形式を示したが、これは前部フレーム体２２の前方や後方、後部フレーム体２４の前方や後方に単数または複数のフレーム体を連結した３本以上の形式や、中間部フレーム体２３を複数本とした３本以上の形式などであってもよい。さらに１本のフレーム体形式とし、その前後端に被案内装置３０を配設した形式などであってもよい。
【００７２】
上記した実施の形態では、フレーム体２２，２３，２４の連結を行う縦方向軸体２７間に支持部６０を設けた形式を示したが、これは中間部フレーム体２３に支持部６０を設けた形式であってもよく、この場合には、カーブ経路などの円滑な移動のために、中間部フレーム体２３として伸縮構造が採用される。
【００７３】
上記した実施の形態では、端部被案内装置５０として前後方向の１箇所に被支持ローラ５３を設けた形式を示したが、これは中間部被案内装置３０と同様に、前後方向の２箇所に被支持ローラを設け、そして下位二股部を有するブラケットや縦方向軸体などを介して本体側に連結させた形式などであってもよい。
【００７４】
上記した実施の形態では、床１側からの機枠１０にレール装置１１やチェーンガイド装置１４などを配設しているが、これは床面下のピット内にレール装置１１やチェーンガイド装置１４などを配設した構成であってもよい。これによると、移動体２０を含めた全体の高さを低く形成できる。
【００７５】
上記した実施の形態では、床１側を移動自在な移動体２０を示したが、これは天井側に配設したレール装置に支持案内されて移動自在な移動体であってもよい。
【００７６】
上記した実施の形態では、レール１２にガイド部１２ａが曲げ成形された構成を示しているが、これはチャンネル状のレールとし、そして開放部側の上縁部に、被ガイドローラ３５，５５を案内するためのガイドフレーム体が固定された形式であってもよい。
【００７７】
【発明の効果】
上記した本発明の請求項１によると、移動体に移動力を付与しての移動の際に、各被案内装置を、各被支持ローラを介してレール装置で支持案内でき、このとき支持部側の荷重（大きな負荷）を、被支持ローラを振り分けて設けた強固な構成の被案内装置によって常に安定して支持できる。そして移動体の移動は、左右方向へのカーブ経路部でも同様にして行うことができ、その際に被案内装置が縦方向軸体とともに回動することで、レール装置の左右方向のカーブに沿って向きを自動的に変更でき、以てカーブ経路部での移動体の移動を円滑に行うことができる。また一定経路中に、上下方向へのカーブ経路部が形成されている場合は、縦方向軸体側に対して被案内装置が左右方向軸の周りに相対回動することで、レール装置の上下方向のカーブに沿って向きを自動的に変更しながら常に円滑に移動できる。
【００７８】
このような移動の際に、縦方向軸体に連結したローラ支持体も一体に回動することになって、左右一対のガイドローラを支持する軸の軸心を一定経路に対して直交状の方向に沿った（合致させた）方向にでき、以てガイドローラを、スリップ（摩擦抵抗）を伴うことなく円滑に回転できる。したがってローラ支持体を、ガイド体に対して引っ掛かることなく、ガタ付くことなく支持案内できることになり、以て被搬送物を支持している移動体の移動を常に安定して円滑に行うことができる。さらに一定経路の全長におけるガイド体の構成、配置（取り合い）を全長に亘って同様にでき、以てガイド体を簡単かつ安価に配設できる。
【００７９】
また上記した本発明の請求項２によると、移動体が一定経路上で移動する際に、各フレーム体は、縦方向軸体を介して左右方向で相対的に屈折した姿勢で移動できる。
【００８０】
そして上記した本発明の請求項３によると、カーブ経路部では、縦方向軸体に連結したローラ支持体も一体に回動することになって、左右一対のガイドローラを支持する軸の軸心をカーブ半径方向に沿った（合致させた）方向にでき、以てガイドローラを、スリップ（摩擦抵抗）を伴うことなく円滑に回転できて、被搬送物を支持している移動体のカーブ経路部における移動を、常に安定して円滑に行うことができる。しかも、カーブ経路部におけるガイド体の構成、配置（取り合い）を直線状経路部と同様にでき、以てカーブ経路部におけるガイド体を簡単かつ安価に配設できる。
【００８１】
さらに上記した本発明の請求項４によると、被搬送物や支持部の荷重の全てを、前後の縦方向軸体を介して被案内装置に直接に伝達でき、さらにトロリ本体に前後に振り分けて設けた被支持ローラを介してレール装置側で支持することができ、以て移動体の移動は、荷重の有無、荷重の大小に関係なく、常に安定して行うことができる。

The present invention has a rail device and a movable body supported and guided by the rail device and movable on a fixed path, and a transport facility using a movable body that supports and transports an object to be transported by the movable body. It is about.
[0002]
[Prior art]
Conventionally, the following configuration has been provided as this type of transfer equipment. That is, the main body of a movable body (movable body) supported and guided by the rail and movable on a fixed path is formed by three frame bodies which are relatively rotatably connected via a connecting device. The frame body is formed of a rectangular body that is long in the direction of the fixed path, and the side surface is formed on the passive surface. The intermediate frame body is provided with an object support portion and a guided device supported and guided by rails, and the front and rear end frame bodies are provided with guided devices supported and guided by rails. Has been.
[0003]
At this time, all the (four) guided devices are rotatably mounted on the end frame body provided on the corresponding frame body, and a vertical pin is rotatably mounted on the lower end of the vertical pin via a left and right direction pin. A trolley body that is movably connected, a total of four supported rollers attached to a pair of front and rear sides on each side of the trolley body, and a total of four guided rollers attached to the top and bottom of the trolley body respectively And a trolley format. An idler wheel is attached to a lower portion of the transported object support portion, and a pair of guide rails for supporting the idler wheel from below are arranged along a fixed path.
[0004]
According to such a conventional type, a driving type in which a plurality of moving bodies are arranged and driven in a tightly pushed state without a gap between the front and rear ends thereof between the feeding device and the braking device can be used. . At this time, the moving body is moved on a fixed path by the supported roller group of each guided device being supported and guided by the rail, and the guided roller group being guided by the guide frame body. Further, since the idler wheels are supported and guided by the guide rails, the load on the transported object support portion side can be supported (for example, see Patent Document 1).
[0005]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 7-25441 (Page 3, Page 5, FIG. 1-3, FIG. 12-13)
[0006]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, the idle wheel group is fixedly disposed in a fixed posture (orientation) with respect to the transported object support portion. Therefore, in the curve path in the left-right direction in a plan view, the axis connecting the left and right idler wheels is oriented parallel to the curve radius, that is, the idler wheel group moves with respect to the curve locus of the guide rail. It is directed in an inclined direction, whereby the idler wheel group undergoes friction rotation with slip (frictional resistance), so that the friction rotation at a plurality of places may not move smoothly. For this reason, the transported object support portion may be supported and guided in the form of being hooked or rattling with respect to the guide rail, so that the moving body may not move smoothly on a curved path. In addition, the configuration and arrangement (arrangement) of the guide rails on the curved path are different from those of the straight path, and thus the arrangement of the guide rails on the curved path is complicated and expensive.
[0007]
Therefore, the invention according to claim 1 of the present invention provides a transfer facility using a moving body, which can always smoothly support the support portion even on a curved path portion and can easily and inexpensively arrange guide rails. It is intended for that purpose.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, a transfer facility using a moving body according to claim 1 of the present invention has a rail device and a moving body supported and guided by the rail device and movable on a fixed path. On the main body side of the moving body, a support portion for the transferred object is provided, and guided devices supported and guided by the rail device corresponding to the front and rear ends thereof are connected, and these guided devices are The lower part of the vertical shaft body from the main body side is connected to the lower part of the vertical shaft body via a left-right axis so as to be relatively rotatable, and a roller support in the left-right direction is connected to the vertical shaft body. Is provided with a guide roller which is supported and guided by a guide body disposed at a predetermined position in a predetermined path.
[0009]
Therefore, according to the first aspect of the invention, each guided device is supported and guided by the rail device at the time of moving while applying a moving force to the moving body, and at this time, the load (large load) on the supporting portion side is guided. May be supported by the device. The movement of the moving body can be performed in the same manner also in the curve path portion in the left and right direction. At that time, the guided device is rotated along with the vertical shaft body, so as to follow the left and right curve of the rail device. You can move while changing the direction automatically. When a curved path portion in the up-down direction is formed, the guided device relatively rotates around the left-right axis with respect to the vertical shaft body side, so that the guided device follows the up-down curve of the rail device. You can move while changing the direction automatically.
[0010]
In such a movement, the roller support connected to the vertical shaft also rotates integrally, so that the axes of the shafts supporting the pair of left and right guide rollers are orthogonal to a certain path. And the guide roller can be smoothly rotated without slip (frictional resistance). Further, the configuration and arrangement (arrangement) of the guide members over the entire length of the fixed path can be made the same over the entire length.
[0011]
According to a second aspect of the present invention, there is provided a transporting facility using a moving body, wherein the three main bodies of the moving body are relatively rotatably connected to each other via a vertical shaft. Guided devices are connected to the main body side corresponding to the front and rear ends of each frame body, and at least the guided device in the middle portion is located on the lower side of the vertical shaft body on the left and right sides. It is characterized by being relatively rotatably connected via a directional shaft.
[0012]
Therefore, according to the second aspect of the present invention, when the moving body moves on a fixed path, each frame body can move in a relatively bent posture in the left-right direction via the vertical shaft body.
[0013]
According to a third aspect of the present invention, there is provided a transfer facility using a moving body, wherein the guide body is provided on a curved path portion in a fixed path in the configuration according to the first or second aspect. Things.
[0014]
Therefore, according to the third aspect of the present invention, in the curved path portion, the roller support connected to the vertical shaft is also rotated integrally, so that the axis of the shaft supporting the pair of left and right guide rollers is curved. It may be in a radial (matched) direction, so that the guide roller can rotate smoothly without slip (frictional resistance). Moreover, the configuration and arrangement (arrangement) of the guide members in the curved path portion can be made the same as in the straight path portion.
[0015]
Further, in the transport equipment using a moving body according to claim 4 of the present invention, in the configuration according to any one of the above-described claims 1 to 3, a supporting portion is provided between upper portions of the vertical shaft body. It is a characteristic.
[0016]
Therefore, according to the invention of claim 4, all of the load of the transported object and the support portion can be directly transmitted to the intermediate guided device via the front and rear vertical shafts, and can be distributed to the trolley body back and forth.

I have. A pair of guide rails (an example of a guide body) 6 for supporting and guiding the idler wheel 66 from below are provided at predetermined locations in the fixed path 5, that is, at predetermined locations in the linear path section 5a and the curved path section 5b. It is arranged along.
[0035]
Note that the guide rail 6 may be provided along the entire length of the fixed path 5, or may be provided mainly at a desired position where the work is supported while supporting the transferred object W. Further, a cover body 7 is provided on the guide rail 6, and the idler wheel 66 may be supported and guided from below by the cover body (another example of the guide body) 7.

[0036]
In the fixed path 5, for example, one straight path section 5 a is penetrated through a drying furnace (an example of a processing section) 9 of the transferred object W. An endless rotary feeder 70 is provided corresponding to the drying furnace 9 to apply a moving force to the moving body 20 by engaging a transmitting body with the passive body 36.
[0037]
That is, the endless rotary feed device 70 is linked with the driving tooth wheel 71 provided at the outlet portion of the drying furnace 9, the driven tooth wheel 72 group provided at the inlet portion of the drying furnace 9, and the like. One example is constituted by the driving device 73 thus wound, the chain 74 wound between the two tooth wheels 71 and 72, and the like. Here, the chain 74 is formed in an endless manner by alternately connecting a pair of upper and lower link bodies 75 and a pair of left and right link bodies 76 by a chain pin body 77, and the connection by the chain pin body 77 is as follows.

Further, a transmission 82 that can be engaged with the passive body 36 is provided between the right and left link bodies 76 at appropriate positions, and the transmission 82 is configured to protrude upward in a higher-order path portion.
[0039]
A chain guide device 14 is provided below the rail device 11 in order to support and guide the chain 74 moved on the upper route portion. In other words, the chain guide device 14 is configured by arranging a pair of left and right channel-shaped rails 15 at the lower portion of the machine frame 10 with their open portions facing each other. An example of the endless rotary feeder 70 is configured by the above 14, 15, 71 to 82 and the like.
[0040]
In a predetermined path portion of the fixed path 5, there is provided a friction-type feeding device 90 that abuts and rotates on the passive surface 25 to apply a moving force to the moving body 20. The friction-type feeding device 90 includes an induction motor 91 with a speed reducer, which is an example of a rotary drive unit, and a feed roller 92 attached to an output shaft that is taken out of the induction motor 91 in a vertical direction. The feed roller 92 has, for example, an outer peripheral portion made of urethane. An example of the friction-type feeding device 90 is configured by the above-described components 91 and 92.
[0041]
The friction-type feeding device 90 can apply a moving force to the moving body 20 by causing a feed roller 92 driven and rotated to abut on the passive surface 25. At this time, the friction-type feeding device 90 may be a stationary type, or in order to obtain a more sufficient contact force, for example, the feed roller 92 is urged against the passive surface 25 by an elastic repulsive force of a compression spring. It may be in a form to obtain. The friction feeders 90 are disposed at predetermined intervals on a predetermined path portion of the fixed path 5, and the arrangement pitch P is shorter than the entire length L of the moving body 20, that is, P <L. Is set.
[0042]
As shown in FIG. 11, an ascending / descending route portion (ascending route portion or descending route portion) 5c is formed in the fixed route 5 as needed. Here, the ascending / descending inclination angle θ in the ascending / descending path portion 5c is set to be smaller as the distance Lα between the supported rollers 53 in the front and rear end guided devices 50 is longer.
[0043]
That is, as shown in Table 1, for example, when the distance Lα between the supported rollers 53 is “4200”, the elevation inclination angle θ can be set to around “30 °”, and the distance between the supported rollers 53 When Lα is “5200”, the elevation tilt angle θ can be set from “15 °” to a value close to “20 °”.
[0044]
[Table 1]

The operation of the above embodiment will be described below.
[0045]
As shown in the imaginary line in FIG. 1 and FIG. 9, in a predetermined path portion excluding the drying furnace 9 in the fixed path 5, the feed roller 92 in contact with the passive surface 25 is driven and rotated by the induction motor 91. By doing so, a moving force (running force) is applied to the moving body 20 by the friction-type feeding device 90, and the moving body 20 can be fed and moved. That is, the movement of the moving body 20 by the friction-type feeding device 90 causes the feeding roller 92 to move the driven surface 25 of the end guided device 50, the passive surface 25 of the front frame body 22, and the passive surface of the intermediate frame body 23. 25, the passive surface 25 of the rear frame body 24 and the passive surface 25 of the end guided device 50 are sequentially acted on.
[0046]
At this time, when the feed roller 92 is acting on the front frame body 22 side, the intermediate frame body 23 and the rear frame body 24 are pulled and moved via the vertical shaft 27, and the intermediate frame body When acting on the front frame body 23, the front frame body 22 side is pushed and moved through the vertical shaft body 27, and the rear frame body 24 side is pulled and moved through the vertical shaft body 27, and further the rear frame body When acting on the side 24, the intermediate frame body 23 and the front frame body 22 are pushed and moved via the vertical shaft 27.
[0047]
During such movement (running), the guided devices 30 and 50 are supported and guided by the two rails 12 of the rail device 11 via the supported rollers 33 and 53, and the guided rollers 35 and 55 are moved. It is guided in contact with the guide portion 12a. At that time, the trolley body 31 of the intermediate guided device 30 is relatively rotatable to the lower forked portion 40 a of the bracket 40 connected to the lower shaft 27 d of the vertical shaft 27 via the left-right shaft 41. Due to the connection, a play is hardly generated at the connection portion.
[0048]
Therefore, even when a large (wide or tall) object to be transported having an eccentric load is conveyed, the inclination of the support portion 60, that is, the object to be conveyed W can be reduced (small), and the conveyance is stabilized. In addition, various operations on the transferred object W and loading and unloading of the transferred object W can always be performed accurately. Moreover, the intermediate guided device 30 for fitting the trolley body 31 to the lower forked portion 40a is small and inexpensive, and thus the whole can be configured at low cost.
[0049]
The above-described movement of the moving body 20 is performed intermittently at the arrangement pitch P of the friction-type feeding device 90. At this time, when the part of the lower friction-type feeding device 90 is empty, the movement is intermittent. Automatic control is performed based on detection by an appropriate detection unit or the like so that feeding is performed. Then, at the position of the friction-type feeding device 90, the moving body 20 is stopped by the non-rotation of the feeding roller 92 and the worker moves on the floor 1 or the main body 21 in a state where the positioning is performed by appropriate positioning means. The user performs various operations on the transferred object W supported by the support unit 60.
[0050]
The movement of the moving body 20 is performed in the same manner in the curved path section 5b in the left-right direction. At this time, in the curve path section 5b, as shown in FIG. 10, the respective frame bodies 22, 23, 24 are moved via the vertical shaft body 27 in a relatively bent posture in the left-right direction. Further, the end guided device 50 is moved in a posture that is relatively bent in the left-right direction with respect to the front and rear frame bodies 22 and 24 via the vertical pins 58.
[0051]
As shown in FIG. 10, the intermediate guided device 30 is supported and guided by the two rails 12 of the rail device 11 via the supported rollers 33 during the movement on the curved path portion 5 b. When the guided roller 35 comes into contact with the guide portion 12a and is guided, the guided roller 35 rotates together with the vertical shaft 27 with respect to the main body 21 side. As a result, the intermediate guided device 30 is supported and guided without being caught on the rail 12 and without rattling, whereby the movement of the moving body 20 on the curved path portion 5b can be always performed smoothly. Become.
[0052]
At this time, as shown by the imaginary line in FIG. 10, the roller support 68 connected to the longitudinal shaft 27 also rotates together, and the axis of the shaft 69 that supports the idler wheel 66 is moved. The direction may be along (matched with) the radius of the curve, so that the idler wheel 66 may rotate smoothly without slip (frictional resistance). Therefore, the roller support 68 is supported and guided without being caught on the guide rail 6 and without rattling, and accordingly, the movement of the moving body 20 supporting the transported object W in the curved path portion 5b. Can always be performed stably and smoothly.
[0053]
Further, the configuration and arrangement (arrangement) of the guide rails 6 in the curved path section 5b can be made the same as those of the linear path section 5a, so that the guide rails 6 in the curved path section 5b can be arranged simply and inexpensively.
[0054]
When the vertical distance between the guide rail 6 and the rail device 11 changes due to the installation accuracy of the guide rail 6, the cylindrical member 67 moves up and down with respect to the upper shaft portion 27a to absorb the difference. Therefore, stable support guidance can always be performed.
[0055]
Further, at the time of movement on the curved path portion 5b, the end guided device 50 is configured such that the pair of front and rear guided rollers 55 is guided by the guide portion 12a, so that the front and rear frame members 22 and 24 can be moved in the longitudinal direction. And relative rotation about the vertical pin 58. At this time, the pair of left and right supported rollers 53 provided at one location between the front and rear guided rollers 55 is positioned with respect to a line connecting the axes of the vertical pins 54 to which the front and rear guided rollers 55 are attached. The supporting roller 53 is rotated in a frictional manner with a slip (frictional resistance).
[0056]
However, since the friction rotation is performed at one place before and after and at a total of two places of a pair of right and left, the influence is not so much affected, and therefore the end guided device 50 does not rattle without being caught on the rail 12. Therefore, the moving body 20 can always be smoothly moved on the curved path portion 5b.
[0057]
In this manner, the moving body 20 that has moved along the curved path section 5b reaches the entrance of the drying furnace 9, and causes the passive body 36 to enter the working path of the endless rotary feeder 70 and stop. Here, in the drying furnace 9, the endless rotary feeder 70 is operated.
[0058]
That is, the chain 74 is moved by the driving device 73 via the tooth wheels 71 and 72. Then, the transmission 82 that is integrally moved with the chain 74 moves from the start end of the action path toward the passive body 36, and first contacts the cam surface 38 d of the coasting prevention body 38. Is swung upward around the horizontal pin 39 as shown by the imaginary line in FIG. 8, so that the transmission 82 passes through the portion of the coast preventing body 38. The transmission 82 contacts the passive surface 36a of the passive body 36 as shown in FIG. 5, thereby moving the moving body 20 integrally.
[0059]
While moving the moving body 20 in the drying furnace 9 in this manner, the drying operation (not shown) is performed on the transferred object W supported by the support unit 60 by the drying unit (not shown). At that time, since only the chain 74 moves in the drying furnace 9, the endless rotary feed device 70 can be configured to be feed resistant to heat and the like, and thus stable operation over a long period of time can be expected. When the moving body 20 tries to coast (runaway) while the moving body 82 is in contact with the passive surface 36 a of the passive body 36, the coasting prevention body 38 coasts. The prevention surface 38a abuts on the transmission 82 to prevent its coasting.
[0060]
When the moving body 20 reaches the outlet of the drying furnace 9, for example, by forming the rail 15 of the chain guide device 14 in a downwardly inclined shape, the transmission body 82 moves downward with respect to the passive body 36, thereby The engagement of the transmission 82 with the transmission 36 is released. As a result, the feed force of the endless rotary feed device 70 is released, and thereafter, the moving force is applied by the friction type feed device 90 described above.
[0061]
At an appropriate place after exiting the drying furnace 9, the work to be transferred W is lowered from the support unit 60, and a new transfer object W is loaded on the support unit 60. In this way, the moving body 20 is circulated on the fixed path 5.
[0062]
In such a circulating movement, all of the load of the transported object W and the support portion 60 is directly transmitted to both the intermediate portion guided devices 30 via the front and rear vertical shafts 27, and then transmitted to the trolley body 31. Therefore, the moving body 20 can be constantly moved irrespective of the presence or absence of the load and the magnitude of the load, by being supported by the rail device 11 via the supported roller 33 provided separately. .
[0063]
Further, in the case where the vertical path 5c in the vertical direction when viewed from the side is formed in the fixed path 5, first, when the front end guided device 50 moves from the circular arc portion to the inclined portion, FIG. As shown in FIG. 12A, the front frame body 22 is bent upward by the left and right direction pins 22D. Next, when the front intermediate guided device 30 moves from the arc portion to the inclined portion, as shown in FIG. The partially guided devices 30 are relatively rotated around the left and right direction shafts 41, respectively. Then, when the rear end guided device 50 moves from the arc portion to the inclined portion, as shown in FIG. 12C, the rear frame body 24 is moved upward through the left and right direction pins 24D. It is bent and moved.
[0064]
Thus, the moving body 20 automatically changes the direction (up-down angle) of the end guided device 50 or the intermediate guided device 30 in accordance with the inclination of the rail 12 in the elevating route portion 5c, while moving the elevating route portion 5c. As shown in FIG. 11, it is smoothly moved up and down in the elevating path section 5c. When going out of the ascending / descending route section 5c, the direction of the bending motion is reversed, and the same movement is performed. Also, when the ascending / descending route section 5c is going down, it is similarly moved.
[0065]
In such a movement, the ascending / descending inclination angle θ in the ascending / descending path portion 5c is set to be smaller as the distance Lα between the supported rollers 53 in the front and rear end guided devices 50 is longer, so that the ascending and descending is performed. The moving body 20 can be smoothly moved in and out of the vertical moving path 5c around the left and right direction pins 24D and the left and right direction shafts 41 at all times.
[0066]
In the above-described embodiment, the rail 12 of the rail device 11 that supports and guides each of the guided devices 30 and 50 has a guide portion 12a that guides the guided rollers 35 and 55 formed on an upper edge thereof, and is bent upward. By doing so, a rail having a guide portion can be easily configured.
[0067]
In the above-described embodiment, the friction-type feeding devices 90 are disposed at predetermined intervals with the arrangement pitch P set to be shorter than the entire length L of the moving body 20, that is, P <L. May be set with P ≒ L or with P> L.
[0068]
In the above-described embodiment, the form in which the moving body 20 is moved in a state where a gap is formed between the front and rear ends in the linear path portion 5a is shown.

【The invention's effect】
According to the first aspect of the present invention, each guided device can be supported and guided by the rail device via each supported roller at the time of movement by applying a moving force to the moving body. The load (large load) on the side can always be stably supported by the guided device having a strong configuration provided with the supported rollers distributed. The movement of the moving body can also be performed in the same manner in the curved path portion in the left-right direction. At this time, the guided device rotates along with the vertical shaft body, and follows the left-right curve of the rail device. The direction can be changed automatically, so that the moving body can smoothly move on the curved path. In addition, when a curved path portion in the vertical direction is formed in the fixed path, the guided device is relatively rotated around the left-right axis with respect to the vertical shaft body side, so that the vertical direction of the rail device is changed. It can always move smoothly while automatically changing the direction along the curve.
[0078]
At the time of such a movement, the roller support connected to the vertical shaft body also rotates integrally, so that the axes of the shafts supporting the pair of left and right guide rollers are orthogonal to a certain path. The guide roller can be rotated in a direction along (aligned with) the direction, so that the guide roller can be smoothly rotated without slip (frictional resistance). Therefore, the roller supporting member can be supported and guided without being caught on the guide member and without rattling, whereby the moving member supporting the transported object can always be moved stably and smoothly. . Further, the configuration and arrangement (arrangement) of the guides over the entire length of the fixed path can be made the same over the entire length, so that the guides can be easily and inexpensively arranged.
[0079]
According to the above-described second aspect of the present invention, when the moving body moves on a fixed path, each frame body can move in a posture that is relatively bent in the left-right direction via the vertical shaft body.
[0080]
According to the third aspect of the present invention, in the curved path portion, the roller support connected to the vertical shaft is also rotated integrally, so that the axis of the shaft supporting the pair of left and right guide rollers is rotated. In the direction along (coincident with) the radius of the curve, so that the guide roller can rotate smoothly without slip (frictional resistance), and the curved path of the moving body supporting the transferred object. The movement in the section can be always performed stably and smoothly. In addition, the configuration and arrangement (arrangement) of the guides in the curved path can be the same as those in the linear path, so that the guides in the curved path can be arranged simply and inexpensively.
[0081]
Furthermore, according to the above-described claim 4 of the present invention, all of the load of the transported object and the support portion can be directly transmitted to the guided device via the front and rear vertical shafts, and further distributed to the trolley body back and forth. It can be supported on the rail device side via the provided supported roller, so that the moving body can always be stably moved regardless of the presence or absence of the load and the magnitude of the load.
[0082]
Further, according to the fifth aspect of the present invention, when the movable body is moved by applying a moving force, each guided device can be supported and guided by the rail device via each supported roller, and each guided device can be supported. The guide can be guided by the rail device via the guide roller, so that the moving body can be stably moved without rattling or falling down. When the moving body moves along the curved path, the guided device is guided by the pair of front and rear guided rollers by the rail device, so that the guided device can be rotated together with the vertical shaft body and is caught by the rail device. Therefore, the moving body can be moved while automatically changing the direction along the left-right curve of the rail device.
