  By the way, since the solenoid valve manifold of Patent Document 1 has a substantially rectangular parallelepiped shape in which each block is connected in one direction, if the number of valve blocks is increased in order to increase the number of fluid pressure devices to be controlled, It is inevitable that the valve manifold will increase in size in the connecting direction. As a result, for example, when the solenoid valve manifold is installed on the mounting table in a posture in which the connecting direction is parallel to the mounting surface, the installation area of the solenoid valve manifold increases due to the addition of the valve block. There is a possibility that a problem arises that the arrangement of other devices on the table must be changed.

Thus, in the conventional configuration, since the degree of freedom of the outer shape of the solenoid valve manifold is low, it is difficult to say that the installation property is sufficiently high, and there is still room for improvement in this respect.

Here, as described above, since the intermediate air supply flow path 81 and the intermediate exhaust flow path 82 are formed at positions facing the valve air supply flow path 34 and the valve exhaust flow path 35, the intermediate block 15 is connected to the electrical block 13.

As shown in FIG. 1, the solenoid valve manifold 1 (block group 2 a) is fixed on the mounting table 3 by inserting installation screws 66 and 74 through brackets 67 and 75.

Next, the operation of the solenoid valve manifold of this embodiment will be described.
In the solenoid valve manifold 1, there is a case where it is desired to increase the number of valve blocks 11 in order to increase the number of fluid pressure devices to be controlled. In such a case, for example, as shown in FIG. 10, a new valve block 11 is added to the block group 2b, and the position of the intermediate block 15 in the block group 2a is replaced with the valve block 11 adjacent to one end in the connecting direction. As a result, the valve block 11 can be expanded while the dimensions in the connecting direction of the block group 2a, that is, the installation area of the solenoid valve manifold 1 is the same as before the expansion. Even if a new block group is added as the valve block 11 is added, the valve block 11 can be added while the installation area of the solenoid valve manifold 1 is kept the same as before the extension.

  For example, when a new device (not shown) is separately installed on the mounting table 3, it may be desired to secure the installation area of the device by reducing the installation area of the solenoid valve manifold 1. In such a case, for example, as shown in FIG. 11, one of the valve blocks 11 on one end side in the connecting direction of the intermediate block 15 in the block group 2a is moved to the block group 2b, and the other valve block 11 is moved to the intermediate block 15 By moving to the other end side in the connecting direction, the dimension in the connecting direction of the block group 2a is reduced without changing the total number of valve blocks 11 of the solenoid valve manifold 1. That is, the installation area of the solenoid valve manifold 1 can be reduced. Even if a new block group is added and the valve block 11 of the block group 2a is moved to the block group, the solenoid valve manifold 1 can be installed without changing the total number of valve blocks 11 of the solenoid valve manifold 1. The area can be reduced.

As described above, according to the present embodiment, the following operational effects can be achieved.
(1) An intermediate laminated hole 89 extending in an orthogonal direction perpendicular to the connecting direction is formed in the intermediate block 15, the block groups 2 a and 2 b are laminated in the orthogonal direction, and the laminated rod 18 is inserted into the intermediate laminated hole 89. Connected to each other.

  According to the above configuration, by increasing or decreasing the number of valve blocks 11 included in the block groups 2a and 2b, the dimensions in the connecting direction of the block groups 2a and 2b change, and the number of block groups stacked in the orthogonal direction is increased or decreased. As a result, the dimension in the orthogonal direction changes, so that the outer shape of the solenoid valve manifold 1 can be changed to various shapes. Therefore, as described above, the valve block 11 is added without increasing the installation area, or the installation area is reduced without changing the total number of valve blocks 11 (without changing the number of controllable fluid pressure devices). be able to.

  (2) An end laminated hole 76 extending in the orthogonal direction is formed in the end block 14 provided in the block group 2a, 2b, and the block group 2a, 2b is added to the intermediate laminated hole 89, and a laminated rod is added to the end laminated hole 76. Since they are connected to each other by inserting 18, the block groups 2 a and 2 b can be firmly connected to each other, and the block group 2 b can be stably supported.

  (3) The intermediate block 15 includes an air supply communication channel 84 that communicates with the intermediate air supply channel 81 and penetrates in the orthogonal direction, and an exhaust communication channel 85 that communicates with the intermediate exhaust channel 82 and penetrates in the orthogonal direction. Formed. Then, the intermediate air supply flow path 81 and the intermediate exhaust flow path 82 of the intermediate block 15 of the block group 2a and the intermediate air supply flow path 81 and the intermediate exhaust flow path 82 of the intermediate block 15 of the block group 2b are connected to the air supply communication flow path 84. And the exhaust communication channel 85 to communicate with each other. Therefore, it is not necessary to provide the supply / exhaust block 12 for each of the block groups 2a and 2b, and the configuration of the solenoid valve manifold 1 can be simplified.
