Description

【0001】
【発明の属する技術分野】
この発明は、例えば多段式立体駐車設備などに使用される横行パレットを有する駐車装置に関する。
【0002】
【従来の技術】
多段式立体駐車設備は、パレット上の車両を下層階から上層階あるいは上層階から下層階に移動させるための昇降機構と、パレットを水平方向に移動させるための横行機構などを備えている。横行機構は、水平方向に延びるレールと、パレットをレールに沿って移動させるモータなどを有している。(例えば下記特許文献1,2参照)。
【0003】
特許文献1の横行機構は、台車(横行パレット)の四隅に配置されたローラのうち2個のローラを、台車の前後方向(台車の長手方向)に延びる駆動軸によって連結し、この駆動軸をモータによって回転させることにより、台車がレール上を走行するようになっている。また、この駆動軸にスプロケットあるいはピニオンを取付け、走行用チェーンあるいはラックに噛合わせることによって、走行中に台車のローラがレール上を滑ることを防いでいる。
【0004】
特許文献2では、横行パレットの四隅の一箇所に駆動ユニットを設け、この駆動ユニットの駆動軸上に位置するスプロケットと床側に固定されるチェーンとにより、横行パレットを駆動するように構成されている。この場合、1個の駆動車輪のみをモータによって回転させるため、駆動軸を短くすることができる。

【特許文献2】
特開平11−36640号公報
【0007】
【発明が解決しようとする課題】
特許文献1の台車(横行パレット)は、図11に示す従来の横行パレット1と同様に、一対のレール2,3に転接する駆動輪4,5が駆動軸6によって連結されている。この駆動軸6が車両の入庫方向に沿って横行パレット1の長手方向に延びているため、駆動軸6がきわめて長くしかも重量が大である。このため横行パレット1が重くかつ製造コストが高くなる要因となり、しかも駆動軸6の長手方向中間部が撓みやすいため、駆動軸6を支持する軸受に大きな荷重が加わる。このため異音が発生したり、軸受の寿命が短くなるなどの問題がある。
【0008】
特許文献2の横行パレットは、モータによって駆動される1個の駆動車輪のみが一方のレールに転接する。このため、駆動車輪および従動車輪が鍔付き車輪の場合に、鍔付き車輪の配置いかんによっては、各鍔付き車輪の鍔部がそれぞれのレールの側面に接することにより異音が発生したり、鍔付き車輪の摩耗が大きいなどの問題が生じる。また、レールの平行度を高精度に施工しないと、鍔付き車輪の鍔部がレールの側面に強く接することがあり、異音が生じやすい。
【0009】
従ってこの発明の目的は、横行パレットがレール上を円滑に走行でき、異音の発生が抑制され、しかも施工が容易な駐車装置を提供することにある。
【0010】
【課題を解決するための手段】
本発明の駐車装置は、互いに平行に配設され水平方向に延びる一対のレールと、車両を乗せるパレット部を有する横行パレットとを具備し、前記横行パレットは、前記一対のレールのうちの一方のレールに転接する鍔付き駆動輪と、前記鍔付き駆動輪を回転させるモータと、前記一方のレールに転接する鍔付き従動輪と、前記一対のレールのうちの他方のレールに転接する第1および第2の鍔無し従動輪とを具備している。
【0011】
この発明の好ましい形態では、前記一方のレールの長手方向に沿って配設された滑り防止部材と、前記モータによって前記鍔付き駆動輪と一体に回転しかつ前記滑り防止部材と係合した状態で該滑り防止部材の長手方向に転動する滑り防止転動体とを具備している。
【0012】
さらにこの発明の好ましい形態では、前記鍔付き駆動輪の直径と、前記滑り防止転動体のピッチ円の直径とを僅かに異ならせることにより、前記横行パレットが移動する際に前記鍔付き駆動輪と前記滑り防止転動体とに周速度差をもたせている。
【0013】
前記滑り防止部材の一例はチェーンであり、前記滑り防止転動体がスプロケットである。あるいは、前記滑り防止部材がラックであり、前記滑り防止転動体が該ラックに噛合うギヤであってもよい。また、前記滑り防止部材が摩擦路であり、前記滑り防止転動体が該摩擦路に転接する摩擦車であってもよい。
【0014】
この発明の好ましい形態では、前記滑り防止部材の一端がレールを支持する支持構造物に固定され、該滑り防止部材の他端が該滑り防止部材に張力を与えるテンション機構を介して前記支持構造物に固定され、該滑り防止部材の長手方向中間部が前記支持構造物に固定せずにフリーな状態としている。
【0015】
【発明の実施の形態】
以下に本発明の一実施形態について、図1〜図8を参照して説明する。
図7に示す多段立体駐車設備において、地上最上段のパレットPと地下最下段のパレットPは、それぞれ昇降機能のみを有しているが、地上1階のパレットPは横行機能を有し、それ以外の中間階のパレットPは昇降機能と横行機能とを有している。これら横行可能なパレットPを、この明細書では横行パレットと称している。
【0016】
図1は横行パレットPを備えた駐車装置10を示している。この駐車装置10は、互いに平行に配設され水平方向に延びる一対のレール11,12と、自動車等の車両13を乗せるパレット部14を有する横行パレットP等を備えている。レール11,12は、梁あるいは床等の支持構造物15,16上に設置されている。
【0017】
横行パレットPは、一対のレール11,12のうちの一方のレール11に転接する鍔付き駆動輪20(図2に示す)と、鍔付き駆動輪20を回転させるモータ21と、該レール11に転接する鍔付き従動輪22(図3,図4に示す)と、他方のレール12に転接する第1および第2の鍔無し従動輪23,24(図5,図6に示す)を備えている。
【0018】
図2に示すように鍔付き駆動輪20は、レール11を挟んでレール11の両側面と向かい合う一対の鍔部30,31を備えている。これら鍔部30,31によって、鍔付き駆動輪20のレール11に対する幅方向の位置が規制される。
【0019】
図4に示すように鍔付き従動輪22もレール11を挟んでレール11の両側面と向かい合う一対の鍔部32,33を備えている。これら鍔部32,33によって、鍔付き従動輪22のレール11に対する幅方向の位置が規制される。
【0020】
図5(A)(B)に示す2つの例では、入庫方向に関して入口側に位置するレール11上に、鍔付き駆動輪20と鍔付き従動輪22を配置し、入口から遠い側に位置するレール12上に、鍔無し従動輪23,24を配置している。この場合、鍔付き駆動輪20と鍔付き従動輪22の位置関係は、図5(A)(B)のいずれであってもよい。
【0021】
図6(A)(B)に示す2つの例では、入庫方向に関して入口側に位置するレール11上に、鍔無し従動輪23,24を配置し、入口から遠い側に位置するレール12上に、鍔付き駆動輪20と鍔付き従動輪22を配置している。この場合も、鍔付き駆動輪20と鍔付き従動輪22の位置関係は、図6(A)(B)のいずれであってもよい。
【0022】
このように、一対のレール11,12のうちのいずれか一方のレールに鍔付き駆動輪20と鍔付き従動輪22を転接させ、他方のレールに鍔無し従動輪23,24を転接させている。これにより、横行パレットPがレール11,12から脱輪することが防止される。
【0023】
また、横行パレットPの四隅のうちの一箇所に設けた鍔付き駆動輪20によって横行パレットPが駆動される際に、横行パレットPのねじれ(ツイスト)が抑制され、1個の鍔付き従動輪20によって横行パレットPを円滑に走行させることが可能となる。
【0024】
これら鍔付き駆動輪20と鍔付き従動輪22とによって、一方のレールに対する幅方向の位置決めがなされるが、鍔無し従動輪23,24は他方のレールに対して幅方向の位置が規制されていない状態となる。このため、レール11,12の平行度が多少悪くても、鍔付き駆動輪20の鍔部30,31とレール11との間、あるいは鍔付き従動輪22の鍔部32,33とレール11との間に過剰な摩擦力が発生することを回避でき、横行パレットPを円滑に移動させることができる。
【0025】
図2に示すように鍔付き駆動輪20の軸40は、パレット部14に設けられた軸受41によって回転自在に支持されている。モータ21の出力軸42に駆動側スプロケット43が取付けられている。軸40に被動側スプロケット44が取付けられている。
【0026】
これらスプロケット43,44間にチェーン等の巻掛け伝動部材45が設けられている。スプロケット43,44と巻掛け伝動部材45等によって、モータ21の回転力を鍔付き駆動輪20に伝達するための動力伝達機構46が構成されている。
【0027】
一方のレール11の側面に沿って滑り防止部材50が配設されている。滑り防止部材50はレール11の長手方向に延びている。滑り防止部材50の一例はチェーンである。
【0028】
図3に示すように、滑り防止部材50の一端50aが支持構造物15に固定されている。滑り防止部材50の他端50bは、滑り防止部材50に張力を与えるテンション機構51を介して支持構造物15に固定されている。この滑り防止部材50は、支持構造物15の上面15aに、支承部材55を介して支持されている。
【0029】
支承部材55の高さに応じて、支持構造物15から滑り防止部材50までの距離H(図2に示す)を所望の寸法に設定することができる。支承部材55の幅W1は、滑り防止部材50の幅W2よりも十分に狭くしている。
【0030】
滑り防止部材50の両端50a,50b以外の長手方向中間部は、支承部材55の上に置かれているだけである。すなわち、滑り防止部材50の長手方向中間部は支持構造物15や支承部材55に固定されることなくフリーの状態である。従って滑り防止部材50は、支持構造物15に対して幅W2方向にある程度移動することができる。
【0031】
前記軸40に、鍔付き駆動輪20と一体に回転する滑り防止転動体60が取付けられている。滑り防止転動体60の一例はスプロケットである。この滑り防止転動体60はモータ21によって鍔付き駆動輪20と一体に回転し、滑り防止部材(例えばチェーン)50と係合した状態で、滑り防止部材50の長手方向に転動するようになっている。
【0032】
図2に示すように鍔付き駆動輪20のレール11との接触箇所の直径をD1とした場合、滑り防止転動体60のピッチ円の直径D2を、D1と僅かに異ならせている。例えばD1をD2よりも数%(例えば0.1〜2%程度)大きくしている。あるいは、D1をD2よりも数%(例えば0.1〜2%程度)小さくしている。
【0033】
こうすることにより、鍔付き駆動輪20のレール11に対する接触箇所の周長と、滑り防止転動体60の滑り防止部材50に対する接触箇所(ピッチ円)の周長とが僅かに異なるため、鍔付き駆動輪20と滑り防止転動体60が一体に回転する際に、鍔付き駆動輪20と滑り防止転動体60との間に僅かに周速度差が生じる。
【0034】
以上説明した軸40と、軸受41と、スプロケット44と、鍔付き駆動輪20と、滑り防止部材60などによって、長尺な駆動軸を必要としないコンパクトで軽量な駆動輪ユニット65が構成される。
【0035】
次に、前記駐車装置10の作用について説明する。
モータ21が回転すると、動力伝達機構46を介して被動側スプロケット44が回転することにより、鍔付き駆動輪20が回転するとともに、滑り防止転動体60も回転する。鍔付き駆動輪20が回転することにより、横行パレットPがレール11,12上を移動する。
【0036】
横行パレットPが移動すると、滑り防止転動体60が滑り防止部材50に係合した状態を保ちながら横行パレットPの移動方向に転動する。このため、鍔付き駆動輪20がレール11上をスリップすることが防止され、レール11上に氷雪や落ち葉等の滑りやすいものがあっても、横行パレットPを確実に移動させることができる。
【0037】
また横行パレットPが移動する際の鍔付き駆動輪20の周速度と、滑り防止転動体60の周速度との間に僅かに差をもたせているため、横行パレットPが移動する際の横行慣性による速度脈動、いわゆる「がた運動」が抑制され、横行パレットPを円滑に移動させることができる。
【0038】
また、滑り防止部材50の下面が支承部材55上に拘束されることなく支持されているため、例えば滑り防止部材50にチェーンが用いられた場合に、チェーンのリンクプレート間に侵入した異物を下方に排出することが容易となり、万一、異物が滑り防止部材50に挟まっても、異物の除去作業を容易に行なうことができる。
【0039】
滑り防止部材50は、その両端50a,50b間にテンションをかけた状態で支持構造物15に両端50a,50bが固定され、滑り防止部材50の長さ方向中間部がフリーな状態となっているため、滑り防止部材50のメンテナンス時になどに、清掃、注油、点検作業などを容易に行なうことができる。
【0040】
また、横行パレットPが移動することに伴い、滑り防止部材50と噛合っている滑り防止転動体60が横行パレットPと同じ方向に移動してゆくため、レール11と滑り防止部材50との平行度が多少悪くても、レール11と滑り防止部材50との間の距離Lがほぼ一定に保たれる。
【0041】
すなわちレール11と滑り防止部材50との間の距離Lが自動調芯されつつ、横行パレットPが移動することになる。このため、レール11と滑り防止部材50との平行度の精度がさほど要求されることなく、レール11と滑り防止部材50を設置する際の工事を容易に行なうことができる。
【0042】
なお図9に示すように、滑り防止部材50の他の例として摩擦路70を採用し、滑り防止転動体60としてゴムタイヤ等の摩擦車71を用いてもよい。この場合には、摩擦車71の外周面が摩擦路70に転接することになる。
【0043】
摩擦車71の中心から摩擦車71と摩擦路70との接触箇所までの距離D2´を、鍔付き駆動輪20の中心からレール11までの距離よりも小さくすることにより、横行パレットPが移動する際に鍔付き駆動輪20の周速度と摩擦車71の周速度との間に数%(例えば0.1〜2%程度)の周速度差をもたせるとよい。
【0044】
なお、滑り防止部材50にラックを用い、滑り防止転動体60にギヤ(ピニオン)を用いてもよい。
【0045】
また図10に示すように、滑り防止部材50を支持構造物15の上面15aに直接乗せるようにしてもよい。この場合も、滑り防止部材50の長さ方向中間部が支持構造物15によって拘束されることなくフリーな状態で支持されるため、滑り防止部材50の下部から異物を排出しやすく、メンテナンスも容易である。
【0046】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a parking device having a horizontal pallet used for, for example, a multi-stage multilevel parking facility.
[0002]
[Prior art]
The multi-stage multi-story parking facility includes an elevating mechanism for moving a vehicle on a pallet from a lower floor to an upper floor or from an upper floor to a lower floor, a traversing mechanism for moving the pallet in a horizontal direction, and the like. The traversing mechanism has a rail extending in the horizontal direction, a motor for moving the pallet along the rail, and the like. (For example, see Patent Documents 1 and 2 below).
[0003]
The traversing mechanism disclosed in Patent Literature 1 connects two rollers among rollers arranged at four corners of a trolley (traversing pallet) by a drive shaft extending in a front-rear direction of the trolley (longitudinal direction of the trolley), and connects the drive shafts. The bogie runs on the rails by being rotated by the motor. Further, a sprocket or a pinion is attached to the drive shaft and meshes with a traveling chain or rack to prevent the rollers of the bogie from slipping on the rail during traveling.
[0004]
In Patent Literature 2, a drive unit is provided at one of the four corners of the traversing pallet, and the pallet is driven by a sprocket located on a drive shaft of the driving unit and a chain fixed to the floor side. I have. In this case, since only one drive wheel is rotated by the motor, the drive shaft can be shortened.
[0005]
[Patent Document 1]
JP-A-9-4260
[Patent Document 2]
JP-A-11-36640 [0007]
[Problems to be solved by the invention]
In a cart (traversing pallet) of Patent Document 1, similarly to the conventional traversing pallet 1 shown in FIG. 11, driving wheels 4 and 5 rollingly connected to a pair of rails 2 and 3 are connected by a driving shaft 6. Since the drive shaft 6 extends in the longitudinal direction of the traversing pallet 1 along the direction of entry of the vehicle, the drive shaft 6 is extremely long and heavy. For this reason, the horizontal pallet 1 is heavy and the manufacturing cost is increased. In addition, since the longitudinal middle portion of the drive shaft 6 is easily bent, a large load is applied to the bearing supporting the drive shaft 6. Therefore, there are problems such as generation of abnormal noise and shortening of the life of the bearing.
[0008]
In the traversing pallet of Patent Document 2, only one drive wheel driven by a motor is in rolling contact with one rail. For this reason, when the driving wheel and the driven wheel are flanged wheels, depending on the arrangement of the flanged wheels, the flange portion of each flanged wheel comes into contact with the side surface of each rail, thereby generating abnormal noise, Problems such as large wear of attached wheels occur. In addition, if the parallelism of the rail is not performed with high accuracy, the flange of the flanged wheel may come into strong contact with the side surface of the rail, and abnormal noise is likely to occur.
[0009]
Accordingly, an object of the present invention is to provide a parking device that allows a traversing pallet to run smoothly on rails, suppresses generation of abnormal noise, and is easy to construct.
[0010]
[Means for Solving the Problems]
The parking device of the present invention includes a pair of rails arranged in parallel to each other and extending in the horizontal direction, and a traversing pallet having a pallet portion on which a vehicle is mounted, wherein the traversing pallet is one of the pair of rails. A flanged drive wheel that rolls on a rail, a motor that rotates the flanged drive wheel, a flanged driven wheel that rolls on the one rail, and first and second wheels that roll on the other of the pair of rails. A second collarless driven wheel.
[0011]
In a preferred embodiment of the present invention, the anti-slip member disposed along the longitudinal direction of the one rail and the motor are rotated integrally with the flanged drive wheel by the motor and engaged with the anti-slip member. An anti-slip rolling element that rolls in the longitudinal direction of the anti-slip member.
[0012]
Further, in a preferred embodiment of the present invention, the diameter of the flanged drive wheel is slightly different from the diameter of the pitch circle of the anti-slip rolling element, so that the flanged drive wheel and the flanged drive wheel move when the transverse pallet moves. A peripheral speed difference is provided between the anti-slip rolling elements.
[0013]
One example of the slip preventing member is a chain, and the slip preventing rolling element is a sprocket. Alternatively, the anti-slip member may be a rack, and the anti-slip rolling element may be a gear that meshes with the rack. Further, the anti-slip member may be a friction path, and the anti-slip rolling element may be a friction wheel rollingly contacting the friction path.
[0014]
In a preferred embodiment of the present invention, one end of the anti-slip member is fixed to a support structure that supports a rail, and the other end of the anti-slip member is connected to the support structure via a tension mechanism that applies tension to the anti-slip member. , And the intermediate portion in the longitudinal direction of the anti-slip member is free from being fixed to the support structure.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION

These pallets P which can be traversed are referred to as traversing pallets in this specification.
[0016]
FIG. 1 shows a parking device 10 provided with a transverse pallet P. The parking device 10 includes a pair of rails 11 and 12 that are arranged in parallel to each other and extend in the horizontal direction, and a transverse pallet P having a pallet portion 14 on which a vehicle 13 such as an automobile is mounted. The rails 11 and 12 are installed on support structures 15 and 16 such as beams or floors.
[0017]
The traversing pallet P includes a flanged drive wheel 20 (shown in FIG. 2) that rolls on one of the rails 11 and 12, a motor 21 that rotates the flanged drive wheel 20, and a rail 21. It is provided with a flanged driven wheel 22 (shown in FIGS. 3 and 4) that rolls and first and second flangeless driven wheels 23 and 24 (shown in FIGS. 5 and 6) that roll contact with the other rail 12. I have.
[0018]
As shown in FIG. 2, the flanged drive wheel 20 includes a pair of flanges 30 and 31 that face both sides of the rail 11 with the rail 11 interposed therebetween. The width direction position of the flanged drive wheel 20 with respect to the rail 11 is regulated by the flange portions 30 and 31.
[0019]
As shown in FIG. 4, the flanged driven wheel 22 also includes a pair of flanges 32 and 33 that face both sides of the rail 11 with the rail 11 interposed therebetween. The positions of the flanged driven wheels 22 in the width direction with respect to the rail 11 are regulated by the flanges 32 and 33.
[0020]
In the two examples shown in FIGS. 5 (A) and 5 (B), a flanged drive wheel 20 and a flanged driven wheel 22 are arranged on the rail 11 located on the entrance side with respect to the entry direction, and are located far from the entrance. Collarless driven wheels 23 and 24 are arranged on the rail 12. In this case, the positional relationship between the flanged drive wheel 20 and the flanged driven wheel 22 may be any of FIGS. 5A and 5B.
[0021]
In the two examples shown in FIGS. 6 (A) and 6 (B), collarless driven wheels 23 and 24 are arranged on the rail 11 located on the entrance side with respect to the entrance direction, and on the rail 12 located on the side far from the entrance. , A flanged drive wheel 20 and a flanged driven wheel 22 are arranged. Also in this case, the positional relationship between the flanged drive wheel 20 and the flanged driven wheel 22 may be any of FIGS. 6A and 6B.
[0022]
Thus, the flanged drive wheel 20 and the flanged driven wheel 22 are rolled on one of the pair of rails 11 and 12, and the flangeless driven wheels 23 and 24 are rolled on the other rail. ing. This prevents the transverse pallet P from derailing from the rails 11 and 12.
[0023]
Further, when the transverse pallet P is driven by the flanged drive wheels 20 provided at one of the four corners of the transverse pallet P, the twist (twist) of the transverse pallet P is suppressed, and one flanged driven wheel is provided. 20 enables the traversing pallet P to run smoothly.
[0024]
The flanged driven wheel 20 and the flanged driven wheel 22 determine the width of one of the rails in the width direction, but the width of the flangeless driven wheels 23 and 24 is regulated relative to the other rail. There is no state. For this reason, even if the parallelism between the rails 11 and 12 is somewhat poor, the flanges 30 and 31 of the flanged drive wheel 20 and the rail 11, or the flanges 32 and 33 of the flanged driven wheel 22 and the rail 11, can be used. Between them can be avoided, and the traversing pallet P can be moved smoothly.
[0025]
As shown in FIG. 2, the shaft 40 of the flanged drive wheel 20 is rotatably supported by a bearing 41 provided on the pallet portion 14. A driving sprocket 43 is attached to an output shaft 42 of the motor 21. A driven sprocket 44 is mounted on the shaft 40.
[0026]
A winding transmission member 45 such as a chain is provided between the sprockets 43 and 44. A power transmission mechanism 46 for transmitting the rotational force of the motor 21 to the flanged drive wheel 20 is constituted by the sprockets 43 and 44 and the wrapping transmission member 45.
[0027]
An anti-slip member 50 is provided along the side surface of one of the rails 11. The anti-slip member 50 extends in the longitudinal direction of the rail 11. One example of the slip prevention member 50 is a chain.
[0028]
As shown in FIG. 3, one end 50 a of the anti-slip member 50 is fixed to the support structure 15. The other end 50b of the slip prevention member 50 is fixed to the support structure 15 via a tension mechanism 51 that applies tension to the slip prevention member 50. The anti-slip member 50 is supported on the upper surface 15 a of the support structure 15 via a support member 55.
[0029]
According to the height of the support member 55, the distance H (shown in FIG. 2) from the support structure 15 to the slip prevention member 50 can be set to a desired size. The width W1 of the support member 55 is sufficiently smaller than the width W2 of the anti-slip member 50.
[0030]
The middle portion in the longitudinal direction other than the both ends 50 a and 50 b of the slip prevention member 50 is merely placed on the bearing member 55. That is, the middle portion in the longitudinal direction of the slip prevention member 50 is free without being fixed to the support structure 15 or the support member 55. Accordingly, the anti-slip member 50 can move to some extent in the width W2 direction with respect to the support structure 15.
[0031]
An anti-slip rolling element 60 that rotates integrally with the flanged drive wheel 20 is attached to the shaft 40. One example of the anti-slip rolling element 60 is a sprocket. The anti-slip rolling element 60 is rotated integrally with the flanged drive wheel 20 by the motor 21, and rolls in the longitudinal direction of the anti-slip member 50 while being engaged with the anti-slip member (for example, a chain) 50. ing.
[0032]
As shown in FIG. 2, when the diameter of the contact portion of the flanged drive wheel 20 with the rail 11 is D1, the diameter D2 of the pitch circle of the anti-slip rolling element 60 is slightly different from D1. For example, D1 is set to be several percent (for example, about 0.1 to 2%) larger than D2. Alternatively, D1 is smaller than D2 by several percent (for example, about 0.1 to 2%).
[0033]
By doing so, the peripheral length of the contact point of the flanged drive wheel 20 with the rail 11 and the peripheral length of the contact point (pitch circle) of the anti-slip rolling element 60 with the anti-slip member 50 are slightly different. When the drive wheel 20 and the anti-slip rolling element 60 rotate integrally, a slight peripheral speed difference occurs between the flanged drive wheel 20 and the anti-slip rolling element 60.
[0034]
The shaft 40, the bearing 41, the sprocket 44, the flanged drive wheel 20, the slip prevention member 60, and the like described above constitute a compact and lightweight drive wheel unit 65 that does not require a long drive shaft. .
[0035]
Next, the operation of the parking device 10 will be described.
When the motor 21 rotates, the driven sprocket 44 rotates via the power transmission mechanism 46, so that the flanged drive wheel 20 rotates and the anti-slip rolling element 60 also rotates. The transverse pallet P moves on the rails 11 and 12 by the rotation of the flanged drive wheel 20.
[0036]
When the traversing pallet P moves, the anti-slip rolling element 60 rolls in the moving direction of the traversing pallet P while maintaining the state of being engaged with the anti-slip member 50. For this reason, the drive wheel 20 with a flange is prevented from slipping on the rail 11, and even if there is a slippery object such as ice and snow or fallen leaves on the rail 11, the traversing pallet P can be reliably moved.
[0037]
In addition, since there is a slight difference between the peripheral speed of the flanged drive wheel 20 when the traversing pallet P moves and the peripheral speed of the anti-slip rolling element 60, the traversing inertia when the traversing pallet P moves is changed. Speed pulsation, that is, the so-called "play" is suppressed, and the traversing pallet P can be moved smoothly.
[0038]
Further, since the lower surface of the anti-slip member 50 is supported without being restrained on the support member 55, for example, when a chain is used as the anti-slip member 50, foreign matter that has entered between the link plates of the chain is lowered. Therefore, even if the foreign matter is caught in the anti-slip member 50, the foreign matter can be easily removed.
[0039]
The both ends 50a and 50b of the anti-slip member 50 are fixed to the support structure 15 in a state where tension is applied between the both ends 50a and 50b, and the middle part in the length direction of the anti-slip member 50 is free. Therefore, at the time of maintenance of the slip prevention member 50, cleaning, lubrication, inspection work, and the like can be easily performed.
[0040]
Further, as the traversing pallet P moves, the anti-slip rolling element 60 meshing with the anti-slip member 50 moves in the same direction as the traversing pallet P, so that the rail 11 and the anti-slip member 50 Even if the degree is slightly worse, the distance L between the rail 11 and the slip prevention member 50 is kept substantially constant.
[0041]
That is, the horizontal pallet P moves while the distance L between the rail 11 and the slip prevention member 50 is automatically aligned. For this reason, the construction at the time of installing the rail 11 and the anti-slip member 50 can be easily performed without requiring much accuracy of the parallelism between the rail 11 and the anti-slip member 50.
[0042]
As shown in FIG. 9, a friction path 70 may be employed as another example of the anti-slip member 50, and a friction wheel 71 such as a rubber tire may be used as the anti-slip rolling element 60. In this case, the outer peripheral surface of the friction wheel 71 comes into rolling contact with the friction path 70.
[0043]
By making the distance D2 'from the center of the friction wheel 71 to the contact point between the friction wheel 71 and the friction path 70 smaller than the distance from the center of the flanged drive wheel 20 to the rail 11, the traversing pallet P moves. At this time, a peripheral speed difference of several percent (for example, about 0.1 to 2%) may be provided between the peripheral speed of the flanged drive wheel 20 and the peripheral speed of the friction wheel 71.
[0044]
Note that a rack may be used as the anti-slip member 50 and a gear (pinion) may be used as the anti-slip rolling element 60.
[0045]
Further, as shown in FIG. 10, the anti-slip member 50 may be placed directly on the upper surface 15 a of the support structure 15. Also in this case, since the middle portion in the length direction of the anti-slip member 50 is supported in a free state without being restrained by the support structure 15, foreign matter is easily discharged from the lower portion of the anti-slip member 50 and maintenance is easy. It is.
[0046]

[0048]
According to the invention described in claim 3, by making the circumference of the flanged drive wheel slightly different from the circumference of the pitch circle of the anti-slip rolling element, speed pulsation due to the transverse inertia of the transverse pallet is suppressed, The traversing pallet can be run more smoothly.

According to the invention as set forth in claims 4, 5, and 6, the use of a chain and a sprocket, a rack and a gear, or a friction path and a friction wheel prevents slippage between the flanged drive wheel and the rail. Thus, the traversing pallet can be reliably driven.
[0050]
According to the invention described in claim 7, both ends of the anti-slip member are supported in a state in which tension is applied to the anti-slip member, and the intermediate portion in the longitudinal direction of the anti-slip member is not restrained, so that the rail and the anti-slip member can be used. Even if the degree of parallelism is somewhat poor, the traversing pallet can be run without any problem, and the parallelism between the rail and the anti-slip member is reduced, thereby facilitating construction. In addition, foreign matter that has entered the anti-slip member can be easily discharged, and maintenance of the anti-slip member is easy.
