【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

この考案は、輪状物品の保持装置と、この保持装置を有したオーバーヘッド型 物品搬送装置とに関する。 The present invention relates to a ring-shaped article holding device and an overhead-type article conveying device having the holding device.

【0002】[0002]

【従来の技術】[Prior art]

従来、この種オーバーヘッド型物品搬送装置として以下の如きものは知られて いる。即ち、上方軌道と、この上方軌道に沿って走行する走行車と、この走行車 に昇降自在に設けられた昇降枠と、この昇降枠に設けられた、タイヤ等の輪状物 品を保持するための保持装置とを有したオーバーヘッド型の物品搬送装置である 。上記保持装置は、相互に離隔・近接自在な一対のハンド片を有しており、これ らハンド片を、相互近接させた状態で輪状物品の中央孔内へ差し入れ、次に相互 離隔させることで、上記中央孔の開口縁に両外側へ向く押圧力を発生させ、これ によって輪状物品の保持力が得られるようにしてある。 Conventionally, the following types of overhead type article conveying devices have been known. That is, in order to hold an upper track, a traveling vehicle traveling along the upper track, an elevating frame provided on the traveling car so as to be able to move up and down, and a ring-shaped object such as a tire provided on the elevating frame. Is an overhead-type article transporting device having a holding device. The holding device has a pair of hand pieces that can be separated and approached to each other, and these hand pieces are inserted into the central hole of the ring-shaped article in a state of being brought close to each other and then separated from each other. A pressing force is generated at the opening edge of the central hole toward both outsides, whereby a holding force for the ring-shaped article is obtained.

【0003】 ところで、上記保持装置は、輪状物品を保持するにあたり、ハンド片を相互離 隔させながら、その途中で離隔動に所定の抵抗が加わったのを検知することによ り、両ハンド片が、輪状物品における中央孔の開口縁に押圧力を発生させたこと (輪状物品の保持が行われたこと)を判断するようになっている。By the way, when holding the ring-shaped article, the above holding device separates the hand pieces from each other, and detects that a predetermined resistance is applied to the separating movement in the middle of the two hand pieces. However, it is determined that the pressing force is generated at the opening edge of the central hole in the ring-shaped article (that the ring-shaped article is held).

【0004】[0004]

【従来技術の欠点】[Disadvantages of the prior art]

従来のオーバーヘッド型物品搬送装置には、保持装置に関して以下の如き欠点 があった。即ち、輪状物品の中央孔における開口縁のうち、両ハンド片が押圧す る箇所の相互は、中央孔の中心を介した対向位置関係を有するようになされてい る。しかし、保持前の輪状物品が位置ズレを起こしていた場合などでは、ハンド 片相互による押圧箇所が中央孔の中心から偏心することがあった。輪状物品がタ イヤ等のゴム製のものであると、中央孔の開口縁に一旦ハンド片が接触した後は 、これら両者間に滑りが生じ難くなるため、偏心状態が矯正されないまま、両ハ ンド片の離隔動に所定の抵抗が加わり、従って、その離隔動が途中で停止するよ うになっていた。それ故、オーバーヘッド型物品搬送装置として、搬送後におけ る輪状物品の位置付けが不正確になったり、或いは搬送途中に輪状物品を落下し たりする欠点があった。 The conventional overhead type article conveying device has the following drawbacks with respect to the holding device. That is, among the opening edges in the central hole of the ring-shaped article, the positions pressed by both hand pieces have an opposing positional relationship via the center of the central hole. However, in the case where the ring-shaped article before being held was misaligned, the points pressed by the hand pieces were sometimes eccentric from the center of the central hole. If the ring-shaped article is made of rubber such as tire, once the hand piece comes into contact with the opening edge of the central hole, slippage between them does not easily occur, so that the eccentricity is not corrected and A certain amount of resistance was added to the separating movement of the handpiece, so that the separating movement stopped halfway. Therefore, the overhead-type article transporting device has a drawback that the positioning of the ring-shaped article after the transportation becomes inaccurate, or the ring-shaped article is dropped during the transportation.

【0005】[0005]

【前記欠点を解消するための手段】[Means for eliminating the above drawbacks]

この考案は前記欠点を解消するために、オーバーヘッド型物品搬送装置の主要 部分である保持装置につき、以下の如き手段を採用した。 即ち、基枠に、輪状物品の中央孔内へ差し込み可能な相互離隔・近接自在とな された一対の垂下保持棒が設けられ、これら垂下保持棒の各外向き部分に、輪状 物品の中央孔の開口縁と接触する水平回転自在な求心用ローラが設けられている ものである。 In order to solve the above-mentioned drawbacks, the present invention adopts the following means for the holding device which is the main part of the overhead type article conveying device. That is, the base frame is provided with a pair of hanging holding rods which can be inserted into the central hole of the ring-shaped article and which can be spaced apart from each other and can be brought close to each other. It is provided with a centering roller that is horizontally rotatable and is in contact with the opening edge of the.

【0006】[0006]

【考案の作用】[Function of the device]

この考案は以下の如き作用をなすものである。 輪状物品の中央孔内へ相互近接させた垂下保持棒を差し込み、相互離隔させる と、中央孔の開口縁には、その相反する箇所に求心用ローラが当接するようにな る。このとき、開口縁に対する求心用ローラの相互の当接箇所が、中央孔の中心 から偏心していても、各求心用ローラが離隔動するのに伴って当該求心用ローラ が水平回転を起こすため、輪状物品は位置的な矯正移動を誘発されるようになる 。そのため、求心用ローラ相互は、常に、中央孔の中心を介した対向位置関係を 有して開口縁を押圧した状態で、輪状物品を保持するようになる。 This device has the following actions. When the hanging holding rods that are close to each other are inserted into the central hole of the ring-shaped article and are separated from each other, the centripetal roller comes into contact with the opposite edges of the opening edge of the central hole. At this time, even if the mutual contact points of the centering rollers with respect to the opening edge are eccentric from the center of the central hole, the centering rollers cause horizontal rotation as the centering rollers move away from each other. The ring-shaped article becomes prone to positional corrective movement. Therefore, the centripetal rollers always hold the annular article in a state of having a facing positional relationship via the center of the central hole and pressing the opening edge.

【実施例の作用】[Operation of the embodiment]

次に実施例装置の作用について説明する。 図1の如く、保持装置Fは、双方の垂下保持棒10,10を相互近接させた状 態で待機している。この状態で、搬送コンベヤ等の物品載置ステーション6上に 置かれた輪状物品Tに対して、走行車2による所定の位置決めと、昇降枠4によ る下降とが行われ、上記両垂下保持棒10,10が、輪状物品Tの中央孔29内 へ差し込まれる(図2及び図5(a)参照)。このときの差し込み深さは、物品 係止片11の上面が、中央孔29の上側の開口縁30より低いレベルとなるよう に調節される。なお、物品載置ステーション6の上面に、輪状物品Tの中央孔2 9に対応する開口部(図示略)を形成したような場合であれば、物品係止片11 の上面が、中央孔29の下側の開口縁30より更に低いレベル(輪状物品Tの下 側)となるまで、昇降枠4を下降させればよい。 Next, the operation of the embodiment apparatus will be described. As shown in FIG. 1, the holding device F stands by in a state in which both of the hanging holding rods 10, 10 are close to each other. In this state, a predetermined position by the traveling vehicle 2 and a lowering by the elevating frame 4 are performed on the ring-shaped article T placed on the article placement station 6 such as a conveyer conveyor, and the above-mentioned drooping holding is performed. The rods 10, 10 are inserted into the central hole 29 of the ring-shaped article T (see FIGS. 2 and 5 (a)). The insertion depth at this time is adjusted so that the upper surface of the article locking piece 11 is at a level lower than the upper opening edge 30 of the central hole 29. In the case where an opening (not shown) corresponding to the central hole 29 of the ring-shaped article T is formed on the upper surface of the article placing station 6, the upper surface of the article locking piece 11 is the central hole 29. It is sufficient to lower the elevating frame 4 until the level becomes lower than the lower opening edge 30 on the lower side (the lower side of the ring-shaped article T).

【0012】 次に、保持装置Fは、垂下保持棒10,10を相互離隔させて、各求心用ロー ラ15,15を、開口縁30の相反する箇所へ当接させるようにする。もし、こ のとき、開口縁30に対する求心用ローラ15,15の相互の当接箇所が、図6 の如く中央孔29の中心Pから偏心していた場合には、各求心用ローラ15,1 5が離隔動しようとする力を受けて、当該求心用ローラ15が開口縁30に沿っ て転がるように水平回転を起こす。そのため、輪状物品Tが、位置的な矯正移動 を誘発されるようになる。結局、求心用ローラ15相互は、常に、中央孔29の 中心を介した対向位置関係を有して開口縁30を押圧した状態となる(図5(b )参照)。Next, the holding device F separates the hanging holding rods 10 from each other so that the centripetal rollers 15 are brought into contact with the opposite positions of the opening edge 30. At this time, if the mutual contact points of the centering rollers 15, 15 with respect to the opening edge 30 are eccentric from the center P of the central hole 29 as shown in FIG. Receives a force to move away from each other, the centering roller 15 horizontally rotates so as to roll along the opening edge 30. Therefore, the ring-shaped article T is triggered to undergo the positional corrective movement. After all, the centripetal rollers 15 are always in a state of facing each other through the center of the central hole 29 and pressing the opening edge 30 (see FIG. 5B).

【0013】 上記のような保持装置Fによる輪状物品Tの保持動作が終わると、昇降枠4が 上昇して輪状物品Tを持ち上げるようになるが、このとき、輪状物品Tの重量を 、物品係止片11によって補助的に支承できるようにしておくのが好ましい。When the holding operation of the ring-shaped article T by the holding device F as described above ends, the elevating frame 4 rises to lift the ring-shaped article T. At this time, the weight of the ring-shaped article T is It is preferable that the stopper 11 can be used for supporting the support.

【0014】 ところで、この考案においては、保持装置Fにつき、垂下保持棒10を備えな い構成とすることも可能である。すなわち、前記した前後動台12(図3参照) と同様に、相互離隔・近接自在となされた一対の移動片(図示略)を設け、これ ら移動片に対し、直接的に、回転軸心を上下方向へ向けるようにして求心用ロー ラ15を設けるようにするのである。なお、上記移動片を相互離隔・近接自在に 移動させる構造としては、上記前後動台12の場合と同様なものでもよいし、上 下方向へ向けた揺動軸を中心として股開き自在となされたフィンガータイプのも のを用いてもよい。By the way, in the present invention, the holding device F may be configured without the hanging holding rod 10. That is, as in the case of the front-rear moving table 12 (see FIG. 3), a pair of movable pieces (not shown) that are freely separated from each other and provided close to each other are provided, and the rotary shaft center is directly attached to the movable pieces. The centripetal roller 15 is provided by orienting the vertical direction. Incidentally, the structure for moving the moving pieces so that they can be separated and approached to each other may be the same as that of the front-rear moving table 12 or can be crotch-opened about an oscillating shaft directed upward and downward. A finger type may be used.

【0015】 また、保持装置Fによる輪状物品Tの保持は、中央孔29の開口縁30を、求 心用ローラ15により相反する方向へ押圧する力により行うものに限らず、物品 係止片11によって輪状物品Tの重量を全面的に支承する如く、吊持させるよう にしてもよい。Further, the holding of the ring-shaped article T by the holding device F is not limited to holding the opening edge 30 of the central hole 29 by the force of pressing the centering roller 15 in opposite directions. The weight of the ring-shaped article T may be suspended so that the entire weight of the ring-shaped article T is supported.

【考案の効果】[Effect of device]

この考案は、前記した如き構成によって以下の如き効果を奏するものである。 輪状物品が位置ズレを起こして載置されていた場合でも、中央孔の開口縁に対 して、その相反する箇所を求心用ローラが両外側へ押圧してゆく過程で、輪状物 品が位置的な矯正移動を誘発されるようになる。そのため、求心用ローラ相互は 、常に、中央孔の中心を介した対向位置関係を有して開口縁を押圧した状態で、 輪状物品を保持するから、確実な保持ができる。 この保持装置を有するオーバーヘッド型物品搬送装置では、搬送後における輪 状物品の位置付けを正確にでき、搬送途中に輪状物品が落下することもない。 The present invention has the following effects due to the above-described configuration. Even if the ring-shaped article is placed with a positional deviation, the ring-shaped article is positioned in the process of the centering roller pressing the opposite points against the opening edge of the central hole toward both outsides. Will be induced to corrective movement. Therefore, the centripetal rollers always hold the ring-shaped article in a state of facing each other through the center of the central hole and pressing the opening edge, so that reliable holding can be performed. In the overhead type article conveying device having this holding device, the annular article can be accurately positioned after being conveyed, and the annular article does not drop during conveyance.
