ものが知られている。2. Description of the Related Art Conventionally, as a fluid pressure cylinder device of this type, as disclosed in Japanese Utility Model Publication No. 1-17723, a fluid pressure cylinder device in which a piston rod is fixed and a tube side is reciprocated is disclosed. , A pair of sprockets are attached to the front and rear ends of the tube, and an endless chain is laid over it, and one of them is fixed to a fixing member such as a frame, and the half circumference of the fixing point is parallel to the axis of movement of the cylinder. It is known that the driven member is connected to a driven member that is freely movable along the guide, and the driven member is moved with a stroke that is twice the stroke of the tube.

If only a double operating speed is obtained and the driven member is to be operated at a high speed, the tube must also be driven at a correspondingly high speed. When driving the tube at high speed,
In particular, the piston ring and the seal ring between the end cover of the tube and the rod are easily worn at an early stage, and further improvement has been desired from the viewpoint of durability.

く長いストローク２ｎＬで駆動されることとなる。When the moving side member, which is one of the tube and the piston, moves due to the supply and discharge of the pressurized fluid to and from the fluid pressure cylinder, the movable pulley attached to the moving side member moves the same distance, and the wire moves accordingly. The driven member is pulled and driven along the guide. At that time, the ratio of the pulling length of the wire to the moving distance of the moving side member of the cylinder is equal to the number of wires wound around the movable pulley and extending in the moving axis direction of the cylinder. Being an individual,
Since there are two wires extending for each, the total becomes 2n times. As a result, when the moving member of the cylinder moves with the stroke L, the driven member is driven with the stroke 2nL which is significantly longer than that.

きる効果がある。According to the present invention, the driven member can be operated with a long stroke, in other words, at a high speed, by slightly moving the moving side member of the fluid pressure cylinder.
The fact that the cylinder side can be driven with a short stroke, that is, at a low speed, reduces the wear of the cylinder seal parts, which can significantly extend the service life, and also makes the cylinder itself compact. There is an effect that can be done.

When the cylinder tube 2 is moved leftward by a distance L / 2 as shown by the chain line in the figure, by supplying pressurized air to and discharging the air from the right piston chamber 9,
Left and right movable pulleys 22a, 22b attached to it
The groups respectively move in the same direction by the same distance, the connecting end of the right side wire 24b with the table 15 is pulled rightward, and the connecting end of the left side wire 24a with the table 15 is extended in the same direction. 15 is driven rightward along the guide bar 13.

Since the number of the movable pulleys 22b and 22a is five, each of which is wound around 22a and extends in the moving direction of the cylinder tube 2, and each of which has two movable pulleys 22b and 22a.
× 2 = 10 times, and the moving distance of the table 15 is (L

The connection end with 15 is extended in the same direction, and the table 1
5 moves 5L to the left.

実現される。That is, when the cylinder tube 2 reciprocates left and right with the stroke L, the table 15 moves to its 10th position.
It is driven with a double stroke 10L, and 10 times higher speed operation is realized.

着したシールリング３１は長寿命となる。As described above, the table 15 operates at a high speed, but the cylinder tube 2 moves at a low speed for a short distance. Therefore, the piston ring 30 fitted to the outer periphery of the piston 3 and the center of the end cover 5 of the tube 2 are moved. The seal ring 31 fitted in the hole 6 has a long life.
