This invention relates to a solenoid valve manifold with a control terminal configured to ensure the following.

In fluid control systems, when a large number of solenoid valves are used in a device or machine, a manifold is often constructed into blocks in order to simplify piping work and reduce the installation space. in this case,
If you try to incorporate a conduit type or grommet type terminal that connects the power supply system and control system wiring into a manifold that connects a solenoid valve, the base that supports the manifold will become extremely large and occupy a large area. Become. As mentioned above, since the manifold itself is intended to make effective use of a narrow space, such an expansion of the occupied area does not meet the purpose of the manifold.
On the other hand, when trying to connect a pair of control conductors 4 to each of a plurality of solenoid valves 2a to 2i arranged in series as shown in FIG. 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, as a result of intensive research and ingenuity, the inventors of the present invention constructed a structure in which the solenoid valves, manifolds, control terminals, etc., were made into blocks so that they could be connected to each other, and each device was connected to each other using conductive wires that formed a bus. If the configuration is such that the jack is attached and connected, it occupies less space and is free from malfunctions.
Furthermore, it has been found that a solenoid valve manifold which is extremely easy to maintain and manage is obtained, and the above-mentioned disadvantages are eliminated.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a solenoid valve manifold with a control terminal that can be easily miniaturized, has fewer failures, and is easy to handle.

In order to achieve the above object, the present invention includes a plurality of solenoid valves, a manifold connected to each of the solenoid valves, and a controller coupled to the solenoid valve or manifold, and the controller has a plurality of solenoid valves connected to each solenoid valve. It includes a control circuit that energizes and deenergizes the solenoid valve, and the controller is configured in a box shape, so that when the solenoid valve, manifold, and controller are integrally combined, it has a substantially rectangular or rectangular parallelepiped shape. Select the height, length, and width of each solenoid valve, manifold, and controller so that It is characterized in that it is sequentially connected to bus line terminals and a plurality of signal lines for controlling the electromagnetic valves are led out from the controller.

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 10 indicates a solenoid valve manifold block, which includes a solenoid valve section 12 and a manifold section 14.
It can be divided into Although not shown, the solenoid valve section 12 includes a valve body and a solenoid constituting each solenoid valve, while the manifold section 14 includes:
Each includes a fluid supply hole 16 and a pair of fluid discharge holes 18, 18 bored on both sides thereof. 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 An insertion conduit 20 and an insertion conduit 22, 22 are fitted into the hole 16 and the fluid discharge holes 18, 18, respectively. That is,
By fitting the insertion conduit 20 and the insertion conduits 22, 22 into the fluid supply hole 16 and the fluid discharge hole 18, 18 of one adjacent manifold block 10, the other manifold block 1
Can be combined with 0. In addition, in FIG. 2, the manifold block 10 located at the end
Fluid supply hole 16 and fluid discharge hole 1 of e
8 and 18 are connected to a fluid supply system 24 and a fluid discharge system 26 and 26, respectively.

Manifold block 10a then connects to controller 28. As can be seen, this controller 28 is similar in width, thickness and height to the respective manifold blocks 10.

a and the controller 28 are firmly attached to each other by suitable fitting means.

By the way, a terminal 30 is fixedly installed on the upper wall of the controller 28, and a conducting wire 32 related to the power supply system and a conducting wire 34 related to the 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 supplies individual control signals for the solenoid valve 12 from a main controller (not shown) to the controller 28 as a serial signal, and
8 converts this serial signal into a parallel signal and sends it to a solenoid valve control circuit 40 built in the controller 28. The solenoid valve control circuit 40 sends the parallelized solenoid valve control signals to the controller 2.
8 is supplied to the bus terminals 44a to 44e of each electromagnetic valve via a bus line 46. In this case, the power source for driving the solenoid valves 12a to 12e is also connected to this bus line 46.

Furthermore, when considering other embodiments of the conductor 34, it is also possible to replace this conductor 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.

Therefore, in this embodiment, the bus line connecting part 50 is attached to the manifold part 14 constituting each manifold block 10, and the electromagnetic valve part 12 is attached to the manifold part 14.

That is, the bus line connection section 50 is made of a box-shaped body 52, and one side wall of the box-shaped body 52 is provided with a terminal portion 56 including a plurality of protruding terminals 54, and the other side wall is provided with a terminal portion 56 including a plurality of protruding terminals 54.

Necessary power and control signals are supplied to the power supply circuit 36 and the conversion circuit 38 via conductive wires 32 and 34 connected to terminals on the side wall of the controller 28, and on the other hand, the power supply circuit 36 and the conversion circuit 38 are supplied with necessary power and control signals to drive each electromagnetic valve. The current and parallelized control signals from the solenoid valve control circuit 40 are fed via a connection 70 containing the bus line 46 to the bus line connection 56 on the manifold block side. That is, the output sides of the power supply circuit 36 and the electromagnetic valve control circuit 40 are connected to the bus line 46, and a receiving portion 72 similar to the terminal receiving portion 58 is provided on one side of the connecting portion 70. . Therefore, the terminal part 56 is fitted into the receiving part 72, and the first receiving part 6 of the bus line connection part 50 having this terminal part 56 is inserted into the receiving part 72.

A power supply conductor 74 in 6 is directly connected to a driver 76, and a solenoid valve 78 is energized and deenergized by this driver 76. On the other hand, the bus line 46 that derives 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.
The data signal supply system 82 is also connected to a data signal transmission/reception circuit 86 . The address signal selection circuit 84 includes an address setting circuit 88
A storage circuit 90 is also provided, the output side of which is connected to the data signal transmitting/receiving circuit 86 on the one hand.

Therefore, the operation of the electric circuit configured as described above will be explained.

The address setting switch 60 is energized to set the address of a predetermined solenoid valve 78 via the address setting circuit 88. This address is temporarily stored in the memory circuit 90 via the address signal selection circuit 84, and is also transmitted to the solenoid valve control circuit 40 via the address signal supply system 80 and stored therein. Therefore, the solenoid valve control circuit 40 sends address signals and control signals, that is, data signals, to the individual solenoid valves. The address signal is sent from an address signal supply system 80, and a data signal supply system 8
When a control signal is sent from 2, the address signal selection circuit 84 selects only the address signal related to its own electromagnetic valve given from the storage circuit 90, and at the same time, the data signal transmission/reception circuit 86 sends the address signal together with the address signal. Only incoming control signals are accepted.

Furthermore, the control state of the solenoid valve 78 is sent from the data signal transmitting/receiving circuit 86 to the solenoid valve control circuit 40 along with the address signal of the address signal selection circuit 84 via the bus line 46 and stored therein.

FIG. 5 shows another embodiment of the invention. In this embodiment, the address setting switch 60 is not attached to the solenoid valve manifold block 10, but is integrated and separated from the block 10.

Furthermore, control signals for individual solenoid valves are transmitted directly from the terminal 92 to the conductor 94 instead of the bus line 46.
is connected to each solenoid valve. In the case of such a structure, manufacturing costs can be further reduced.

FIG. 6 shows yet another embodiment of the present invention.

In this embodiment, control of the solenoid valve is performed by optical signals. Therefore, optical fibers 96 and 98 are used in place of the conductors 32 and 34, and the manifold section 14 is constructed to be somewhat large to accommodate optical signals/
An electric signal conversion circuit 100 was added, and drivers 76 corresponding to the number of electromagnetic valves 78 were collectively arranged. This is to stabilize operation using optical signals.
