[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manifold solenoid valve in which a plurality of solenoid valves are mounted on a manifold block having a supply port and an exhaust port.

[0002]

2. Description of the Related Art In general, a manifold solenoid valve is provided with a plurality of solenoid valves mounted on a manifold block having an air supply port and an exhaust port, and supplies fluid pressure to each solenoid valve and exhausts fluid pressure. This is an electromagnetic valve of a type that is operated by a common air supply port and an exhaust port formed in a manifold block. However, a type of manifold solenoid valve in which only the air supply port is formed in the manifold block and exhaust from each solenoid valve is directly performed from the solenoid valve has been developed.

[0003] Since such a manifold solenoid valve can centrally control a plurality of pneumatic actuators, it is frequently used when a large number of pneumatic actuators are used as in an assembly line for parts or products. I have.

[0004]

The connection between a plurality of solenoid valves mounted on a manifold block and a pneumatic actuator such as a pneumatic cylinder is performed in a manifold piping system in which a manifold block is provided, and in each of the solenoid valves. There is a valve piping system. The valve piping method has the advantage that the solenoid valve can be replaced with a single valve, and the manifold piping method has the advantage that the solenoid valve can be replaced without removing the piping.

[0005] Which method is selected is determined according to the place where the manifold solenoid valve is used. However, once one is selected, the method cannot be easily changed later. When the specification is changed to another type, it is necessary to replace the manifold solenoid valve with another type.

SUMMARY OF THE INVENTION An object of the present invention is to provide a manifold solenoid valve in which the piping system of the manifold solenoid valve can be changed to any of the above-described manifold piping system and valve piping system.

[0007] The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

As shown in FIG. 2A, the solenoid valve 2 is fastened to the manifold block 1 by two screw members 26. The other solenoid valves 3 to 5 are similarly fastened to the manifold block 1 by two screw members 26.

FIG. 3 shows that the closing member 31 is fastened to the valve body 6 of the solenoid valve 2 by a screw member 27, and the connecting member 41 is fastened to the manifold block 1 by the screw member 27 corresponding to the solenoid valve 2. The state is shown. The closing member 31 and the connecting member 41 are detachable, and the closing member 31 and the connecting member 41 can be exchanged.

As shown in FIGS. 4A and 4B, the closing member 31 is formed of a substantially rectangular plate 32, and an inner surface of the plate 32 has a respective valve-side output port. A seal material 33 for sealing the output ports 24 and 25 or the manifold side output ports 24 and 25 is attached, a screw hole 34 for the screw member 27 to penetrate is formed, and the solenoid valve 2 is connected to the manifold block 1. A notch 35 is formed to avoid interference with the screw member 26 for fastening.

For example, in the case shown in the figure, each connection member 41 is provided with two pipe members 43, but if a connection member 41 having only one pipe member 43 is prepared, a single-acting type Fluid pressure can also be supplied to the cylinder. Although the illustrated solenoid valve is a 5-port solenoid valve, the number of ports is not limited to this, and a 3-port solenoid valve may be mounted. Further, the manifold block 1 has an air supply port 2 in the illustrated case.
