Furthermore, by incorporating the solenoid valve control circuit and the serial/parallel signal conversion circuit into a block controller, maintenance management becomes even easier.

[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 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,
Fluid supply hole 16 and fluid discharge hole 18, 1 of one adjacent manifold block 10
8, the insertion conduit 20 and the insertion conduits 22, 22.
It can be connected to the other manifold block 10 by fitting it. In addition, in FIG. 2, the fluid supply hole 16 and fluid discharge holes 18, 18 of the manifold block 10e located at the end end are connected to a fluid supply system 24 and a fluid discharge system 26, 26, respectively. I'll keep it.

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 to 10e, and 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 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 connects the solenoid valve 12

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, 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 section 56 including a plurality of protruding terminals 54, and the other side wall is provided with a terminal section 56 including a plurality of protruding terminals 54. A terminal receiving portion 58 is provided in which a terminal 54 provided on the bus line connecting portion 50 is fitted and received. Also,

A first receiving portion 64 is provided on the rear surface of the box-like body 52 to receive a pair of first terminals 62, 62 protruding from one side of the manifold portion 14. A second pair of terminals 66, 66 are further provided on the upper surface of the manifold portion 14, and a receiving portion 68 is provided on the bottom of the electromagnetic valve portion 12 in correspondence with these terminals 66, 66. controller 28
is mounted and fixed on the upper surface of the manifold section 14. Inside the controller 28, a power supply circuit 36, a serial signal/parallel signal conversion circuit 38, and a solenoid valve control circuit 40 are arranged as in the previous embodiment. The power supply circuit 36 and the conversion circuit 38 have a conductor 3 connected to a terminal on the side wall of the controller 28.
Necessary power and control signals are supplied via the power supply circuit 2 and 34, while each electromagnetic valve drive current from the power supply circuit 36 and the parallelized control signal from the electromagnetic valve control circuit 40 are supplied via a built-in bus line 46. Connection part 7

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 terminal 62,
62, and then the second terminals 66, 66 are fitted into the receiving portion 68 of the solenoid valve portion 12, and in this way, the required number of manifold blocks 10 can be installed in series.

Therefore, the address setting switch 60 is used to energize an address setting circuit (described later) in the bus line connection section 50, and the address of the solenoid valve forming the manifold block 10 is specified.

The electric circuit of the bus line connection section 50 including the address setting circuit described above will be explained in FIG.

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 supplies address signals and control signals, that is, data signals, for each solenoid valve. 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 is supplied with the address signal. Only incoming control signals are accepted.
This is transmitted to the driver 76, and the driver 76 is energized based on the control signal, thereby controlling the opening and closing of the solenoid valve 78. Furthermore, the control state of the electromagnetic valve 78 is supplied to the electromagnetic valve control circuit 40 from the data signal transmission/reception circuit 86 together 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.
Moreover, control signals for individual solenoid valves are transmitted via the bus line 4.
A terminal 92 instead of 6 is directly connected to each electromagnetic valve by a conductor 94. 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 conductive wires 32 and 34, the manifold section 14 is configured to be somewhat large, the optical signal/electrical signal conversion circuit 100 is added, and the number of drivers 76 corresponding to the number of electromagnetic valves 78 is increased. were arranged and configured all at once. This is to stabilize operation using optical signals.

[Effects of the Invention] As described above, the present invention includes a solenoid valve block body, a manifold block body, and a controller block body, and the controller block body controls the individual solenoid valves therein. It has a serial/parallel signal conversion circuit that converts a serial control signal to a parallel control signal, and a control circuit that energizes and deenergizes each of the electromagnetic valves.

Therefore, by connecting the blocks to each other, the occupied space can be reduced, the space can be used effectively, and the assembly work can be simplified. Moreover, since the serial/parallel signal conversion circuit for the electromagnetic valves is provided in the controller block, the wiring for the individual electromagnetic valves will not be mixed up, and the risk of malfunction of the electromagnetic valves will be reduced. Furthermore, specific effects such as easier maintenance management can be obtained.
