に、回動自在に取り付けられている。FIG. 1 is a side view of an opening / closing mechanism according to the present invention, and FIG. 2 is a front view thereof. A drive shaft 2, which is connected to a drive body 1 such as a motor and rotates, is rotatably supported by a bearing base 4 fixed to the upper surface of a can body 3. A driven shaft 5 is further supported on the bearing base 4 above the drive shaft 2, and the driven shaft 5 is provided in parallel with the drive shaft 2. Further, one ends of the drive arms 6, 6 are rotatably attached to both ends of the drive shaft 2, and the other ends are rotatably attached to pedestals 9, 9 on the left and right side peripheral portions of the can lid 7 facing each other. Has been. Similarly, one end of each of the driven arms 8 and 8 is rotatably attached to both ends of the driven shaft 5, and the other ends of the pedestals 9 and 9 are fixed to the peripheral portions of the left and right side surfaces of the can lid 7 facing each other. It is rotatably mounted at a position above the mounting position of the drive arm 6 and above the center of gravity of the can lid 7.
上記駆動アーム６と従動アーム８は同一平面上にあるた

に回転力を付与する。A weight 10 is integrally connected to one end of the driven shaft 5 outside the driven arm 8 via a support column 11. This is almost the same as the weight of the can lid 7.
When the opening of the can body 3 is closed, the support column 11 is fixed in a state of vertically extending. Therefore, in such a state, the weight 10 applies a rotational force to the driven shaft 5. Does not work. On the other hand, when the drive shaft 2 rotates to move the can lid 7 while being supported by the drive arm 6 and the driven arm 8, the support column 11 is inclined, as will be described later. , The rotation force is applied to the driven shaft 5 through the driven arms 8 in the direction of lifting the can lid 7.
以下、缶蓋７の開閉作動について説明する。The opening / closing operation of the can lid 7 will be described below.
先ず缶蓋７が缶本体３の開口部に嵌合し、これを閉じて

従動軸５が矢印Ｃ方向に回転すると、ウェイト10が缶本

蓋７を吊り上げる方向に回転力を付与するようになる。
したがって、缶蓋７を吊り上げる駆動体１は、僅かな力
で缶蓋７を吊り上げることができ、非常に効率的であ
る。First, when the can lid 7 is fitted into the opening of the can main body 3 and is closed, the drive arms 6 and 6 and the driven arms 8 and 8 are, as shown in FIG. 2 and below the driven shaft. When the drive shaft 2 is rotated by the drive body 1 in the direction of arrow A, and the drive arms 6, 6 start turning in the direction of arrow B accordingly, the can lid 7 is separated from the opening, and the driven arm 8, 8 also turns with this. These drive arms 6, 6 and driven arm 8,
Each of the eight turns in a trajectory as shown in FIG. 1,
When the can lid 7 reaches the driven shaft 5 above the can body 3, the turning is stopped and the can lid 7 is opened. in this case,
When the driven shaft 5 rotates in the direction of the arrow C, the weight 10 gradually inclines rearward of the can body 3, and the weight 10 applies a rotational force to the driven shaft 5 in the direction of lifting the can lid 7.
Therefore, the driving body 1 that hoists the can lid 7 can hoist the can lid 7 with a small force, which is very efficient.
反対に、缶蓋７を閉じる、即ち原位置に復帰させる場合
には、ウェイト10の重量が、従動軸５及び従動アーム
８、８を介して、缶蓋７の移動方向とは反対の方向に作
用するので、旋回中における駆動アーム６、６、駆動軸
２、及び駆動体１に対する缶蓋７の重量負荷を大幅に軽
減することができる。On the contrary, when the can lid 7 is closed, that is, when the can lid 7 is returned to the original position, the weight of the weight 10 passes through the driven shaft 5 and the driven arms 8 and 8 in the direction opposite to the moving direction of the can lid 7. Since it acts, the weight load of the can lid 7 on the drive arms 6, 6, the drive shaft 2, and the drive body 1 during the turning can be significantly reduced.
したがって、本開閉機構では、駆動体１、駆動軸２、又
は駆動アーム６、６等の耐久性が向上し、それらの破損
や劣化による缶蓋７の落下を有効に防止することがで
き、さらには、缶蓋７の開閉が僅かな力で行なえ、作動
中の缶蓋７の姿勢も安定し揺動が生じにくいので操作が
容易である。Therefore, in the present opening / closing mechanism, the durability of the driving body 1, the driving shaft 2, the driving arms 6, 6, etc. is improved, and the can lid 7 can be effectively prevented from dropping due to damage or deterioration thereof. The can lid 7 can be opened and closed with a small force, the posture of the can lid 7 during operation is stable, and swinging is unlikely to occur, so that the operation is easy.
また万一、上記駆動アーム６、６が破損し、これが缶蓋

を維持することができる。Even if the drive arms 6 and 6 are damaged and cannot support the can lid 7, they are supported by the weight 10, the driven shaft 5 and the driven arms 8 and 8, and thus the can lid 7 is supported.
Does not fall, and further, since they support the upper part of the center of gravity of the can lid 7, the can lid 7 which is not supported by the drive arms 6, 6 rotates in the direction of arrow D, It is also possible to prevent an accident. That is, the can lid 7 can maintain its posture due to its own weight even if the drive arms 6 and 6 are unsupported.

きる。[Effects of the Invention] As described above, the present invention is connected to a drive shaft that is rotated by a driving body, suspends and swivels a can lid, and reciprocates the can lid in the vertical direction of the can body to open the can. A driving arm for opening and closing the portion, a driven arm that is coaxially connected, supports the can lid above the center of gravity of the can lid, and swivels as the drive arm swivels, and the driven shaft. When the lid body is closing the opening of the can body, the lid body is erected vertically and does not apply a rotational force to the driven shaft, and when the drive shaft rotates and the lid body moves. Since the weight that gives a rotational force to the driven shaft is provided in the direction in which the lid is tilted and the lid is lifted, the drive shaft and the drive arm are assisted by the weight, the driven shaft, and the driven arm, and the durability is greatly improved. It also has the effect of ensuring sufficient safety.
Further, according to the present invention, since the pivotally attached portion of the driven arm to the lid body is the outer side portion above the center of gravity of the lid body, the posture of the lid body that opens and closes the opening formed in the lateral direction of the can body. Therefore, it is possible to prevent the collision accident to the operator which may occur when the lid body is rotated with respect to the driven arm and is inverted, for example, because it can be suspended and held without changing.
