以下本発明の実施の形態を図面に基づき説明する。まず、図1~図4において、ワーク反転装置は、ワークを水平軸心周りに90度反転可能な水平反転部1と、水平反転部1により反転されたワークを垂直軸心周りに反転可能な垂直反転部2とを隣接して備えている。水平反転部1と垂直反転部2は、共通の基台3に設けられている。 The following describes an embodiment of the present invention with reference to the drawings. First, in Figs. 1 to 4, the workpiece inversion device includes a horizontal inversion unit 1 capable of inverting a workpiece by 90 degrees around a horizontal axis, and a vertical inversion unit 2 adjacent to each other, capable of inverting a workpiece inverted by the horizontal inversion unit 1 around a vertical axis. The horizontal inversion unit 1 and the vertical inversion unit 2 are mounted on a common base 3.

水平反転部1は、互いに直交するワーク当接面4を水平状態と垂直状態とに位置変更可能に有する。水平反転部1は、基台3に水平軸心周り回動自在に設けられた回転体5を有する。この回転体5にワーク当接面4が設けられている。 The horizontal inversion unit 1 has mutually orthogonal workpiece contact surfaces 4 that can be changed between a horizontal state and a vertical state. The horizontal inversion unit 1 has a rotating body 5 that is mounted on the base 3 so as to be freely rotatable about a horizontal axis. The workpiece contact surface 4 is provided on this rotating body 5.

図1に示すように、ワーク当接面4は、第1面4aと第2面4bがL形に設けられている。第1面4aと第2面4bは同形の正方形に形成されているが、このような形状に限定されるものではない。第1面4aが水平状態のとき、第2面4bは垂直状態である。 As shown in FIG. 1, the workpiece contact surface 4 has a first surface 4a and a second surface 4b that are L-shaped. The first surface 4a and the second surface 4b are formed into identical square shapes, but are not limited to this shape. When the first surface 4a is horizontal, the second surface 4b is vertical.

回転体5は、第1面4aと第2面4bを支持している。回転体5は、その外周面が円弧面に形成されている。この円弧面の下面を支持する支承ローラ(図示省略)が基台3に設けられている。 The rotating body 5 supports the first surface 4a and the second surface 4b. The outer peripheral surface of the rotating body 5 is formed into an arcuate surface. A bearing roller (not shown) that supports the underside of this arcuate surface is provided on the base 3.

図2及び図4に示すように、回転体5は、左右一対設けられてワーク当接面4を支持する。この回転体5を水平軸心周りに回動させる駆動装置(図示省略)が基台3に設けられている。 As shown in Figures 2 and 4, a pair of rotating bodies 5 are provided on the left and right sides to support the workpiece contact surface 4. A drive device (not shown) that rotates the rotating bodies 5 around a horizontal axis is provided on the base 3.

図1の第1面4aが水平状態から、駆動装置により、回転体5を水平軸心周りに90度回転させると、第1面4aは垂直状態となり、第2面4bが水平状態となる。 When the drive unit rotates the rotor 5 90 degrees around the horizontal axis from the horizontal state of the first surface 4a in FIG. 1, the first surface 4a becomes vertical and the second surface 4b becomes horizontal.

ワーク当接面4の第2面4bが水平状態において、垂直反転部2は、ワーク当接面4bに接続される水平状態のワーク載置面6を有する。ワーク載置面6は基台3に固定されている。ワーク載置面6は、第1面4aまたは第2面4bとほぼ同じ大きさとされている。 When the second surface 4b of the workpiece contact surface 4 is in a horizontal state, the vertical inversion unit 2 has a horizontal workpiece placement surface 6 connected to the workpiece contact surface 4b. The workpiece placement surface 6 is fixed to the base 3. The workpiece placement surface 6 is approximately the same size as the first surface 4a or the second surface 4b.

垂直反転部2は水平状態の第2面4bに連接するように設けられているが、水平状態の第1面4aに連接するように設けられていても良い。垂直反転部2は水平反転部1の片側に設けたものに限らず、両側に設けられていても良い。 The vertical inversion section 2 is provided so as to be connected to the second surface 4b in the horizontal state, but it may also be provided so as to be connected to the first surface 4a in the horizontal state. The vertical inversion section 2 is not limited to being provided on one side of the horizontal inversion section 1, and may also be provided on both sides.

基台3は一体構造に限らず、水平反転部1と垂直反転部2とを個々に設けた別体構造であっても良い。 The base 3 is not limited to an integrated structure, and may be a separate structure in which the horizontal inversion section 1 and the vertical inversion section 2 are provided separately.

図5~図8において、上記ワーク反転装置を用いてワークWを反転させる方法を説明する。図5に示すように、ワークWをクレーン等で吊り持ちして、水平反転部1のワーク当接面4の第1面4a上に下ろす。ワークWは、その上面に凹部7が形成された直方体である。ワークWの下面を第1面4aに当接させ、ワークWの右側面を第2面4bに当接させる。この状態で、回転体5を90度矢印方向に回転させる。以上の工程を「第1反転工程」という。 Figures 5 to 8 explain a method for inverting a workpiece W using the above-mentioned workpiece inversion device. As shown in Figure 5, the workpiece W is suspended by a crane or the like and lowered onto the first surface 4a of the workpiece contact surface 4 of the horizontal inversion unit 1. The workpiece W is a rectangular parallelepiped with a recess 7 formed on its upper surface. The lower surface of the workpiece W is brought into contact with the first surface 4a, and the right side surface of the workpiece W is brought into contact with the second surface 4b. In this state, the rotating body 5 is rotated 90 degrees in the direction of the arrow. The above process is referred to as the "first inversion process."

図6に示すように、90度反転後、ワークWを垂直反転部2のワーク載置面6上に移動させる。この移動は、手動で行っても良く、クレーン等の持ち上げ装置を利用して移動させても良い。手動で移動可能な軽量物の場合、ワーク当接面4とワーク載置面6は同一水平面上に位置するのが良いが、重量物でクレーン等の移動装置を用いる場合は、両者間に段差があってもよい。 As shown in FIG. 6, after the 90-degree inversion, the workpiece W is moved onto the workpiece placement surface 6 of the vertical inversion unit 2. This movement may be done manually or by using a lifting device such as a crane. In the case of a lightweight object that can be moved manually, it is preferable that the workpiece contact surface 4 and the workpiece placement surface 6 are located on the same horizontal plane, but in the case of a heavy object and a moving device such as a crane is used, there may be a step between the two.

ワークWを垂直反転部2において垂直軸心周りに180度反転させる。この反転は、軽量物の場合は手動で行い、重量物の場合は、クレーン等で吊り下げた状態で行われる。以上の工程を「第2反転工程」という。 The workpiece W is inverted 180 degrees around the vertical axis in the vertical inversion section 2. This inversion is done manually for light weight objects, and is done while suspended by a crane or similar for heavy weight objects. The above process is called the "second inversion process."

図7に示すように、垂直反転部2で180度反転されたワークWを水平反転部1に移動させる。ワークWの凹部7を有する面を、第1面4aに当接させる。この状態で、図示矢印方向に水平反転部1を90度回転させる。 As shown in FIG. 7, the workpiece W that has been inverted 180 degrees by the vertical inversion unit 2 is moved to the horizontal inversion unit 1. The surface of the workpiece W that has the recess 7 is brought into contact with the first surface 4a. In this state, the horizontal inversion unit 1 is rotated 90 degrees in the direction of the arrow in the figure.

図8に示すように、この90度回転により、第1面4aは最初の水平状態に戻り、この第1面4aにワークWの凹部7を有する面が載置された状態になる。すなわち、ワークWは、図5に示す凹部7が上方を向いた状態から180度反転して凹部7が下方を向いた状態になる。以上の工程を「第3反転工程」という。 As shown in Figure 8, this 90-degree rotation returns the first surface 4a to its initial horizontal state, and the surface of the workpiece W having the recess 7 is placed on this first surface 4a. In other words, the workpiece W is inverted 180 degrees from the state in which the recess 7 faces upward as shown in Figure 5, so that the recess 7 faces downward. The above process is called the "third inversion process."

しかして、この実施の形態では、90度反転装置を用いてワークを180度反転させることができる。 In this embodiment, the workpiece can be rotated 180 degrees using a 90-degree rotation device.

なお、前記第2反転工程でワークWを垂直軸心周りに180度反転させたが、90度反転でもよい。90度反転の場合は、第5図におけるワークWの前面又は後面が、第3反転工程の後に、図8において、下面側になる。 In the second inversion step, the workpiece W is inverted 180 degrees around the vertical axis, but it may be inverted 90 degrees. In the case of a 90-degree inversion, the front or rear surface of the workpiece W in FIG. 5 becomes the lower surface in FIG. 8 after the third inversion step.

第5図におけるワークWの前面又は後面が下面になるようワークの姿勢を変更しようとする場合、クレーンで吊り下げてひっくり返す危険な作業を行うことなく、90度反転装置を用いて安全に姿勢変更することができる。 When changing the position of the workpiece W in Figure 5 so that its front or back surface faces downward, the position can be changed safely using a 90-degree inversion device without the risk of hanging it with a crane and flipping it over.

図9、図10に示すものは、本発明の他の実施の形態である。垂直反転部2において、ワーク載置面6内に回転テーブル8が設けられている。この回転テーブル8は垂直軸心周りに回転するものである。この回転テーブル8は、昇降装置9により昇降自在とされている。回転テーブル8の上面がワーク載置面6より上方に移動可能とされている。回転テーブル8は、駆動式又は遊転式の何れであっても良い。 Figures 9 and 10 show another embodiment of the present invention. In the vertical inversion section 2, a rotating table 8 is provided within the workpiece mounting surface 6. This rotating table 8 rotates around a vertical axis. This rotating table 8 can be raised and lowered freely by a lifting device 9. The upper surface of the rotating table 8 can be moved above the workpiece mounting surface 6. The rotating table 8 may be either a driven type or a free-rotating type.

水平反転部1のワーク当接面4から垂直反転部2のワーク載置面6上に移動されたワークWは、回転テーブル8の上昇及び回転によりその姿勢を90度又は180度変更自在とされている。姿勢変更後、回転テーブル8は下降し、ワークWをワーク載置面6に下ろす。その後、ワークWは水平反転部1のワーク当接面4上に移動させられる。 The workpiece W, which has been moved from the workpiece contact surface 4 of the horizontal inversion unit 1 onto the workpiece placement surface 6 of the vertical inversion unit 2, can freely change its position by 90 degrees or 180 degrees by raising and rotating the rotating table 8. After changing the position, the rotating table 8 lowers and places the workpiece W onto the workpiece placement surface 6. The workpiece W is then moved onto the workpiece contact surface 4 of the horizontal inversion unit 1.

なお、図示省略するが、ワーク載置面6にフリーローラが配置されたものであっても良い。フリーローラによりワークWの水平移動および垂直軸周りの回転を容易とする。 Although not shown, free rollers may be arranged on the workpiece mounting surface 6. The free rollers facilitate the horizontal movement and rotation of the workpiece W around the vertical axis.

今回開示された実施の形態はすべての点で例示であって制限的なものではない。 The embodiments disclosed herein are illustrative in all respects and are not limiting.
