Description

  The present invention relates to a solenoid valve manifold that is integrally provided with at least three solenoid valves in the width direction of a manifold base.

  A generally known solenoid valve manifold is formed by arranging a large number of solenoid valves in parallel along the length of the manifold base on the manifold base, supplying and discharging pressure fluid into the manifold base, and the manifold base. Alternatively, an output pipe is connected to the solenoid valve itself. However, since the solenoid valve manifold has a large number of solenoid valves arranged in a line, the solenoid valve manifold needs at least a length obtained by multiplying the width of the solenoid valve by the number of solenoid valves. For this reason, when the number of solenoid valves increases, the solenoid valve manifold becomes longer, and further miniaturization of the solenoid valve manifold has been desired.

Patent Document 1 discloses a technology that achieves the intensive mounting of a large number of solenoid valves by improving the manifold base, thereby reducing the size of the solenoid valve manifold. As shown in FIG. 10, the manifold base 80 has a solenoid valve mounting body 82 standing thereon, and includes a solenoid valve mounting surface 83 on the back side surface of the solenoid valve mounting body 82. Each electromagnetic valve mounting surface 83 is formed with a flow passage opening 83a for supplying and discharging pressure fluid. Each opening 83 a communicates with a pipe joint 84 provided on the lower surface of the base 81 through a flow path in the electromagnetic valve mounting body 82. When the electromagnetic valve 85 is attached to each electromagnetic valve attachment surface 83 of the electromagnetic valve attachment body 82, the two electromagnetic valves 85 are juxtaposed in the width direction of the manifold base 80, and a number of electromagnetic valves are arranged in the length direction. 85 are juxtaposed. For this reason, for example, the length of the solenoid valve manifold in the length direction can be halved as compared to the case where a large number of solenoid valves 85 are arranged in a line in the length direction of the manifold base 80.

  A solenoid valve 40 is attached to each solenoid valve mounting surface 22a by screwing. When the length direction of the solenoid valve 40 is the axial direction of the solenoid valve 40, the solenoid valve 40 is attached such that the first end 40 e in the axial direction faces the manifold base 12. In the electromagnetic valve 40, the opposite side of the first end 40e in the axial direction is a second end 40f. In this mounted state, the air supply hole 40a of the electromagnetic valve 40 communicates with the air supply port 22c of the electromagnetic valve mounting surface 22a, and the exhaust hole 40b of the electromagnetic valve 40 communicates with the exhaust port 22d of the electromagnetic valve mounting surface 22a. The output hole 40c of the solenoid valve 40 communicates with the output port 22e of the solenoid valve mounting surface 22a. Four electromagnetic valves 40 are arranged in a row in the width direction of the manifold base 12.

  In the pair of solenoid valves 40 attached to the solenoid valve attachment surface 22a facing the back of each attachment adapter 20, the lead terminals L extending from both solenoid valves 40 are electrically connected to the central connector 30 (see FIG. 2). . The central connector 30 is provided on the upper side of each mounting adapter 20 and is disposed between the second ends 40 f of the pair of solenoid valves 40.

The cover 38 is made of a transparent or semi-transparent material, and the display device 37 can be turned on or off through the cover 38.

  In each electromagnetic valve 40, the valve body 43 slightly moves due to the operation of the plunger 42 that moves by energizing the solenoid coil 41. Then, the air supply hole 40a and the output hole 40c communicate with each other, and either the state in which the exhaust hole 40b is sealed or the state in which the exhaust hole 40b and the output hole 40c communicate with each other and the air supply hole 40a is sealed is selected. Is done.

  That is, when the solenoid coil 41 is excited, the plunger 42 moves, and the valve element 43 slightly moves in the same direction by the urging force of the valve element spring 44. Then, the air supply hole 40a and the output hole 40c are communicated, and the communication of the air supply hole 40a and the output hole 40c with respect to the exhaust hole 40b is blocked. As a result, the air supply port 13 and the output port 15 communicate with each other, and the exhaust port 14 is blocked from the air supply port 13 and the output port 15. In this state, positive pressure air supplied to the air supply port 13 is supplied from the output port 15 to the fluid pressure device.

It will be in a state of communication. In this state, the output port 15 and the exhaust port 14 communicate with each other, and the exhaust pressure discharged from the fluid pressure device to the output port 15 is discharged to the exhaust port 14.

The two air supply ports 22c are shared, and one air supply passage 24 is in communication. That is, the air supply passage 24 that communicates with the air supply hole 40a of each electromagnetic valve 40 is shared by a pair of back-facing electromagnetic valves 40. Accordingly, the positive pressure air that has passed through one air supply passage 24 is branched in two directions toward the electromagnetic valve mounting surface 22a in the electromagnetic valve mounting portion 22, and the air supply holes of the electromagnetic valves 40 are supplied from the respective air supply ports 22c. 40a.

  Further, the solenoid valve mounting portion 22 is formed with an exhaust port 22d that opens to a pair of back facing solenoid valve mounting surfaces 22a.

That is, the exhaust passage 25 communicating with the exhaust hole 40 b of each electromagnetic valve 40 is shared by one between the pair of electromagnetic valves 40 facing backward. Therefore, the exhaust pressure discharged from the exhaust hole 40b of each electromagnetic valve 40 merges into one exhaust passage 25 and is discharged from the exhaust port 14 to the atmosphere via the exhaust passage 25.

Thus, the electromagnetic valve mounting portion 22 can be reduced in size. Therefore, when the same number of solenoid valves 40 are made into manifolds, four solenoid valves 40 are arranged in parallel in the width direction of the manifold base 12, compared to arranging one or two solenoid valves 40 in the width direction. Thus, the length of the manifold base 12 in the length direction can be shortened.

For this reason, compared with the case where the display apparatus 37 is provided concentrating on the electric power feeding block 35, the solenoid valve 40 in an energized state can be visually recognized correctly.

  (5) One supply passage 24 and one exhaust passage 25 formed in the electromagnetic valve mounting portion 22 are provided. For this reason, for example, as compared with the case where two supply passages 24 and two exhaust passages 25 are formed in the electromagnetic valve mounting portion 22, the manufacturing cost of the electromagnetic valve mounting portion 22 and the electromagnetic valve manifold 10 can be reduced.

  (6) Four solenoid valves 40 are arranged in parallel in the width direction of the manifold base 12. The manifold base 12 has a rectangular shape, and the manifold base 12 is integrally provided with an air supply port 13, an exhaust port 14 and an output port 15.
