題がある。However, with a structure using such a coil spring, when adjusting a machine equipped with a cam mechanism, or when you want to move only the part that is moved by the lever of the cam mechanism without moving the entire machine, the cam is used. There was a problem that the adjustment work was complicated. Also, in the case of a coil spring, if you try to increase the displacement of the cam follower, the length of the coil spring must be several times the amount of displacement in order to keep the cam follower pressed against the cam surface with a constant force. However, there is a problem in that a large installation space requires a large installation space.

A chamber 15 on one side of the piston 14 of the air cylinder 11, that is, a chamber 15 on the piston rod side in this embodiment, and a chamber 16 on the opposite side are connected to a control valve 20 via speed controllers 17 and 18, respectively. . A relief valve 19 is also connected to the chamber 15, and is configured to release the air pressure when the air pressure in the chamber becomes higher than a predetermined pressure. The control valve 20 is connected to an air pressure source 23 via a regulator 21 and a filter 22.

に接続されたロッド８を介して他の装置に伝えられる。In the above configuration, when the cam mechanism is activated, the cylinder 11
One of the chambers 15 is connected to an air pressure source 23 via a control valve 20 (when the control valve is not energized), and a constant air pressure is introduced into the chamber 15. Therefore, one end of the lever is always pressed toward the cam by air pressure, and the cam follower 7 is also pressed against the cam surface 4. When the cam is rotated in the direction of the arrow under such conditions, the cam follower 7 rolls in contact with the cam surface, but the cam follower 7 rolls in contact with the cam surface.
When moving from a to the trough 3b, the piston 14 is pushed by the air pressure acting on the cylinder 11 and follows the cam surface. Conversely, when the cam follower 7 moves from the valley to the peak, the piston 14 moves in the opposite direction due to the action of the cam, and the pressure in the chamber 15 increases, or the pressure
It is released by the J IJ valve 19 and does not interfere with the operation of the cam. In this way, due to the rotation of the cam, the lever 5
rotates around a fulcrum 6, and its movement is transmitted to other devices via a rod 8 connected to the other end of the lever.

カムフォロアがカムから離れる方向に移動する。If you want to operate only the lever 5 for machine adjustment, etc., rotate the cam so that the cam follower 7 is at the trough 3b of the cam, operate the control valve 20 at that position, and then move the cylinder 11. When the chamber 16 on the other side is connected to the nitrogen source 23 and air pressure is introduced into the chamber 16, one end of the lever 5 moves in the direction in which the cam follower moves away from the cam.
