Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a solenoid valve manifold.

[0002]

[Prior art]

 Conventionally, for the purpose of high integration and space saving, a solenoid valve manifold in which a plurality of solenoid valves are attached to a manifold base having a fluid supply passage inside is used. The wiring cord of each solenoid valve of this solenoid valve manifold is connected to a centralized connector provided in a connector block fixed to the manifold base. Then, a connection cable is connected to this centralized connector from a program controller or the like, and each solenoid valve of the solenoid valve manifold is driven. D-sub connectors and flat cable connectors are used as this centralized connector.

When the solenoid valve manifold is installed in various devices, the installation state such as the position and direction of the manifold varies. Therefore, the connection direction that can connect the connection cable to the solenoid valve manifold without any trouble depends on the installation state of the solenoid valve manifold, and the direction of the centralized connector is required to be in that connection direction. For this reason, the direction of the centralized connector of the solenoid valve manifold was prepared in the vertical direction and the horizontal direction. Then, the vertical type and the horizontal type were used properly according to the connection direction according to the installation state of the solenoid valve manifold.

[0004]

[Problems to be solved by the device]

 However, once the solenoid valve manifold provided with the vertical type or horizontal type centralized connector is installed, the surroundings of the installation space may be changed. And, due to this change, the orientation of the centralized connector of the installed solenoid valve manifold may be incorrect. In this case, in order to set the centralized connector in an appropriate direction, it was necessary to replace the centralized connector for each electromagnetic manifold with an appropriate direction. As a result, extra man-hours and costs required for the change were generated.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a solenoid valve manifold capable of changing the direction of a centralized connector in an installed state.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a plurality of supply / discharge ports and corresponding supply / discharge ports for controlling the supply of fluid from the supply / discharge ports. A solenoid valve manifold body provided with a solenoid valve provided and a supply passage for supplying fluid to each supply / discharge port was provided with a centralized connector for connecting a wiring cord connected to each solenoid valve. The gist of the solenoid valve manifold is that the direction of the centralized connector can be changed.

According to the second aspect of the present invention, the connector block is fixed to the solenoid valve manifold, and the connector housing holding the centralized connector is rotatably supported on the connector block.

[0008]

[Action]

 Therefore, according to the first aspect of the invention, the solenoid valve provided with the supply passage for supplying the fluid and the plurality of supply ports and provided corresponding to each supply port is connected from the supply passage to each supply port. The wiring cord connected to each solenoid valve of the solenoid valve manifold that controls the supply of the fluid is connected to the centralized connector. When the direction of this centralized connector is changed, the direction of the centralized connector changes with the solenoid valve manifold installed.

According to the second aspect of the invention, the connector block is fixed to the solenoid valve manifold main body, and when the connector housing supported by this connector block is rotated, the orientation of the connector main body changes. . Therefore, when the connector housing is rotated with the solenoid valve manifold body installed, the orientation of the centralized connector changes.

Further, a part of the supply air sent to the supply port 6 is supplied as pilot pressure from the pilot pressure supply passage 10 of the supply / exhaust block 1 to the pilot pressure supply passage 16 of each valve block 2. Has become.

When each pilot valve portion 18 a, 18 b of each valve block 2 is actuated, a pilot pressure supplied from the pilot pressure supply passage 16 operates a spool (not shown) so that the supply passage 14 and one Air is supplied by communicating with the cylinder port 21. At the same time, the other cylinder port 21 and the exhaust passage 15 are communicated with each other to perform exhaust, and the exhaust is conducted from the exhaust port 7 to the outside through the exhaust passage 9.

Next, the operation of the solenoid valve manifold configured as described above will be described. When the solenoid valve manifold is installed in the device, the direction of connecting the connection cable C from the program controller to the D sub-connector 24 of the connector block 3 is vertical or horizontal with respect to the solenoid valve manifold. consider.

When it is determined that it is preferable to connect the connection cable C vertically to the solenoid valve manifold, the screw 31 of the connector block 3 is loosened, and the connector housing 23 is set as shown in FIGS. Then, the D-sub connector 24 is rotated so as to face the vertical direction. Then, when the screw 31 is tightened in this state, the connector housing 23 is fixed. In this case, the connection cable C can be vertically connected to the installed solenoid valve manifold.

Then, the solenoid valve manifold can be driven in a state in which the connection cable C is connected to the installed solenoid valve manifold in a reasonable connection direction without interfering with surrounding devices.

In this case, the connection cable C can be connected to the installed solenoid valve manifold from the horizontal direction.

As described above, according to the solenoid valve manifold of the present embodiment, the orientation of the D sub connector 24 can be changed by rotating the connector housing 23. Therefore, it is possible to set the orientation of the D sub-connector 24 to any suitable orientation of the vertical direction or the horizontal direction according to the optimal connection direction of the connection cable C which differs depending on the installation state of the solenoid valve manifold.

Furthermore, according to the solenoid valve manifold of the present embodiment, even after the solenoid valve manifold is installed, even if the constraint on the connection cable C in the installation space changes and the optimum connection direction for the solenoid valve manifold changes. The orientation of the D sub-connector 24 can be changed to the vertical or horizontal orientation, whichever is appropriate, without the need to replace parts.

Further, since the solenoid valve manifold can be installed without any restriction on the connecting direction of the connecting cable C, the installation space and the degree of freedom of position are increased. The present invention is not limited to the above embodiment, and may be configured as follows, for example, without departing from the spirit of the invention.
