[Prior Art] In fluid control systems, when a large number of solenoid valves are used in equipment or machinery, it is common practice to construct a manifold into blocks in order to simplify piping work and reduce installation space. be exposed. In this case, if you try to incorporate a conduit type or grommet type terminal that connects to the wiring of the power system and control system into the manifold that connects the solenoid valve, the base that supports the manifold will become extremely large and occupy a large area. growing.

[Problems to be Solved by the Invention] As described above, since the manifold itself is intended to effectively utilize a narrow space, such an expansion of the occupied area does not meet the purpose of the manifold. On the other hand, as shown in FIG. 1, when a pair of control conductors 4 are to be connected to each of a plurality of solenoid valves 2a to 21 that are arranged in series, there is a gap between the solenoid valves 2a to 21 and a control device (not shown). Not only do the wiring become jumbled, but the wiring occupies a large space, and if the wiring becomes long, there are various problems such as malfunction of the solenoid valve due to external signals.

Therefore, an object of the present invention is to provide a solenoid valve manifold that can be easily miniaturized, has fewer failures, and is easy to handle.

[Means for Solving the Problems] In order to solve the above problems, the present invention comprises a solenoid valve manifold block including a plurality of solenoid valves and a manifold in which the solenoid valves are arranged in series, and the solenoid valves are connected to each other. The solenoid valve manifold block is characterized in that a plurality of manifold blocks are arranged in series, and the electromagnetic valve manifold blocks are electrically connected to each other by a centrally wired and compatible connection part.

``Function'' The solenoid valve, manifold, connection part, etc. are divided into blocks, and each block is connected to each other by the centrally wired connection part, so it occupies less space and is free from malfunctions, and is also extremely easy to maintain. A solenoid valve manifold is obtained.

[Embodiments] Next, preferred embodiments of the solenoid valve manifold according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 2, reference numeral 1O indicates a solenoid valve manifold block, and this manifold block 10 can be divided into a solenoid valve section 12 and a manifold section 14. Although not shown, the solenoid valve section 12 includes a valve body and a solenoid constituting each solenoid valve, while the manifold section 14 has a fluid supply hole 16 and holes on both sides thereof. It includes a pair of fluid evacuation holes 18.18. The required number of manifold blocks 10 can be arbitrarily arranged in series (for example, manifold blocks 10a to 10e are shown in FIG. 2), and for this reason, one side of the manifold section 14 for fluid supply Hole 1
6 and the fluid evacuation hole 18.18 are fitted with an insertion conduit 20 and an insertion conduit 22.22, respectively. That is, by fitting the insertion conduit 20 and the insertion conduit 22.22 into the fluid supply hole 16 and the fluid discharge hole 18.18 of one adjacent manifold block 10, it is connected to the other manifold block 10. be able to. In addition, in FIG. 2, the fluid supply hole 16 and the fluid discharge hole 18.18 of the manifold block 10e located at the end end are connected to the fluid supply system 24 and the fluid discharge system 26.2G, respectively. I'll keep it.

Next, the manifold block lOa is connected to the controller 2
Connect to 8. As can be understood from the figure, this controller 28 is in the same width, thickness and height as the respective manifold blocks 10a to 10e,
Therefore, these manifold blocks and the controller can define a uniform surface with respect to each other.

In this case, although not shown, the manifold block 10a and the controller 28 are securely engaged with each other by suitable fitting means.

By the way, there is a terminal 3 on the clay wall of the controller 28.
0 is fixedly installed, and a conducting wire 32 relating to a power supply system and a conducting wire 34 relating to a control signal supply system are connected to this terminal 30. Each of the conductive wires 32 and 34 is connected to a power supply circuit 36 and a serial signal/parallel signal conversion circuit 38 built into the controller 28. That is, the conductor 34 sends individual control signals for the solenoid valves 12 from a main controller (not shown) to the controller 28 in the form of serial signals, and the conversion circuit 38 converts the serial signals into parallel signals and sends them to the controller 28. Solenoid valve control circuit 4 built in

Power for driving the electromagnetic valves 12a to 12e is also supplied via this bus line 46.

Further, each of the electromagnetic valves 12a to 12e may include an address signal recognition circuit.

That is, when the solenoid valve control circuit 40 sends control signals to each of the solenoid valves 12a to 12e with an address attached, each solenoid valve 12a to 12e selects and utilizes only the control signal corresponding to its own address. becomes possible. Therefore, the signal transmission circuit can be simplified.

Furthermore, when considering another embodiment of the conducting wire 34, it is also possible to replace this conducting wire 34 with an optical fiber. In this case, it goes without saying that a separate optical signal/electrical signal conversion circuit must be provided inside the controller 28.

On the other hand, the bus line 46 for deriving the output of the solenoid valve control circuit 40 is divided into an address signal supply system 80 and a data signal supply system 82, and the address signal supply system 80 is connected to the address signal selection circuit 8.
