Description

Detailed Description of the Invention The present invention relates to a solenoid valve manifold, and more specifically, in a solenoid valve manifold in which a plurality of solenoid valves are arranged in series, a control terminal for energizing and deenergizing each solenoid valve. is attached to the solenoid valve manifold, and the width, length, height, etc. of each solenoid valve, manifold block, and control terminal are connected as close to the same dimensions as possible to ensure uniformity in shape and easy attachment and detachment. This invention relates to a solenoid valve Mayubold with a control terminal configured to ensure safety.

In fluid control systems, when a large number of solenoid valves are used in a device or machine, it is often done to construct a manifold 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 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. 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 21 arranged in series as shown in FIG.
Not only do the wiring get mixed up between the controller and the control device (not shown), but the wiring also occupies a large space.If the wiring becomes long, external signals can cause various problems such as malfunction of the solenoid valve. or existed.

Therefore, as a result of intensive research and ingenuity, the inventors of the present invention constructed a structure in which solenoid valves, manifolds, terminals for control l-rolls, etc. were made into blocks so that they could be connected to each other.
Moreover, if each device is configured to be connected to each other using a lotus conductor with a shack, a solenoid valve manifold that occupies a small area and is free from malfunctions and is also extremely easy to maintain can be obtained. It was found that the inconvenience was eliminated.

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

To achieve the above object, the present invention includes a plurality of solenoid valves, a manifold in which the solenoid valves are arranged in series, and a controller coupled to the solenoid valves or manifolds, and the controller is configured to control each solenoid valve. It is characterized by including a control circuit that energizes and deenergizes the.

Next, a preferred embodiment 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, 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, FIG. 2 shows manifold blocks 10a to 10e), and therefore,
Fluid supply hole 16 on one side of the manifold part 14
Insertion conduits 2o and insertion conduits 22.22 are fitted into the fluid discharge holes 18.18, 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 Mayu Bold block 10, it is connected to the other manifold block 1o. can do. 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 26.26, respectively. I'll keep it.

Next, the manifold block 10a is connected to the controller 2.
Connect to 8. As can be understood from the figure, this controller 28 is approximately the same in width, thickness, and height as each of the 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 controller 28 are securely engaged with each other by suitable fitting means.

By the way, there is a terminal 3 on the upper 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 conductive wire 34 sends individual control signals for the solenoid valve 12 from a main controller (not shown) to the controller 28 as a serial signal, and the conversion circuit 38 converts this serial signal into a parallel signal and sends it to the controller 28. It is sent to the built-in solenoid valve control circuit 40. The electric key valve control circuit 40 sends parallelized electromagnetic valve control signals from a bus terminal 42 attached to the side wall of the controller 28 to path terminals 44a to 44e of each electromagnetic valve via a bus line 46. In this case, the bus line 46 also supplies power for driving the solenoid valves 12a to 12e.

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 other embodiments 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.

Therefore, in this embodiment, each manifold block 1
At the same time, the helical wire connection part 50 is attached to the manifold part 14 constituting the

Inside the controller 28, a power supply circuit 36, a serial signal/parallel signal conversion circuit 3, and a solenoid valve control circuit 4o are arranged as in the previous embodiment. The power supply circuit 36 and the ml conversion circuit 38 are supplied with necessary power and control signals via conductors 32, 34 connected to terminals on the side wall of the controller 28, while each electromagnetic valve from the power supply circuit 36 is supplied with the necessary power and control signals. The drive current and the parallelized control signal from the electromagnetic valve control circuit 40 are sent to the bus line connection 56 on the manifold block side via the connection 70 containing the path line 46. That is, the output sides of the power supply circuit 36 and the electromagnetic valve control circuit 40 are connected to the helical wire 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 portion 56 is fitted into the receiving portion 72, the first terminal 62, 62 is fitted into the first receiving portion 64 of the bus line connection portion 50 having the terminal portion 56, and the receiving portion of the solenoid valve portion 12 is further fitted.

On the other hand, the path 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, and the address signal supply system 80 is connected to the address signal selection circuit 82.
The data signal supply system 82 is also connected to a data signal transmission/reception circuit 86 . The address signal selection circuit 84 is connected to the address setting circuit 88 and is also provided with a memory circuit 90, and an output example thereof is as follows.
