Abstract

PURPOSE:To flexibly cope with the change of a electromagnetic valve configuration with a miniaturized and light weight equipment by arranging a serial/ parallel converting means in a space necessarily generated due to the linkage between the electromagnetic valve, and a manifold, and connector-connecting the means with the electromagnetic valve. CONSTITUTION:A serial/parallel converting means reception (receiving unit) 4 is housed in a space 7 necessarily generated by linking a manifold 5 to an electromagnetic valve 6, and it is directly connected with the electromagnetic valve 6 on a connector-connector basis. A serial signal transmitted from a transmitting unit 2 is converted and amplified to a parallel signal before a transmission according to a rule fixed in the receiving unit 4, and outputted to an electromagnetic wave connector 8. The electromagnetic connector 8 is arranged at the mounting position of the electromagnetic valve 6 on the receiving unit 4, and it can be automatically and instantaneously connected by mounting the electromagnetic valve 6 on the manifold 5. Thus the wiring of cables is utterly unnecessary, and can flexibly cope with the configuration change of the electromagnetic valve with the miniaturized equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a wiring-saving system device for electrical wiring between a programmable controller (hereinafter referred to as PC) and a solenoid valve.

BACKGROUND OF THE INVENTION In recent years, a serial transmission-to-parallel conversion method has been used as a method for connecting a solenoid valve from a PC with the aim of reducing wiring, improving reliability, and improving maintenance of production equipment. A typical conventional example is shown in Drama 5, Figure 6.

In conventional examples 1 and 2 shown in FIGS. 5 and 6, ll is P
C512 is a parallel-to-serial conversion and transfer means (hereinafter referred to as a transmission unit); 13 is a signal transmission means consisting of a serial transmission cable; 14 is a serial-to-parallel conversion means (hereinafter referred to as a reception unit); 15 is a multiple manifold. , 16 are pneumatic solenoid valves.

Problems to be Solved by the Invention A conventional solenoid valve wiring-saving system configured as described above will be described. First, in conventional example 1 shown in FIG. 5, the wiring from the transmitting unit 12 to the receiving unit 14 is connected by one serial transmission cable 13, which saves wiring, but the wiring from the receiving unit 14 to the solenoid valve 16 is The number of solenoid valves required is equal to the number of solenoid valves, and there are problems with wiring assembly man-hours, reliability, appearance, etc.

Furthermore, in the conventional example 2 shown in FIG. 6, the manifold 1
5 with a receiving unit 14 fixed on the top.

It is composed of an attached solenoid valve 16, and is similar to the conventional example 1.
The wiring between the receiving unit 14 and the electromagnetic valve 16, which is a problem in the above, is done within the manifold, which is effective in reducing the number of wiring steps and improving the appearance. However, due to its structure, electrical wiring between the receiving unit 14 and the solenoid valve 16 is required.
Significant problems remain in terms of reliability and cost. Furthermore, the size of the receiving unit is larger than that of the solenoid valve 16 and manifold 15, and precision automatic machines are becoming increasingly smaller in size (making it difficult to put them to heavy use).

In addition, in the case of Conventional Example 1 and Conventional Example 2, if the determined solenoid valve configuration is later changed or added, it is necessary to change the electrical wiring or change the address of the solenoid valve managed by the PC program. Therefore, it was very time consuming. (?Ef solenoid valve configurations include differences in the number of solenoid valves used and types such as single solenoid valves or double solenoid valves.) In view of the above problems, the present invention has been developed to completely reduce wiring,
The present invention also provides a solenoid valve wiring-saving system device that is small and lightweight and can flexibly respond to changes in the solenoid valve configuration.

Means for Solving the Problems The solenoid valve wiring-saving system device of the present invention includes a transfer means for converting a predetermined number of parallel output signals into serial signals and transmitting the same, a means for transmitting the serial signals, and a transmission means for transmitting the serial signals. Serial - converts the signal back to the parallel signal
The device comprises a parallel conversion means, a manifold used in pneumatic control, and a solenoid valve for transmitting driving force, and the serial-to-parallel conversion means is arranged in a space created by coupling the manifold and the solenoid valve. , is characterized by being connected to a solenoid valve using a connector.

According to the above structure of the present invention, by arranging the serial-parallel converting means in the space inevitably generated by combining the solenoid valve and the manifold and connecting the solenoid valve with a connector, the wiring assembly man-hours and the appearance are reduced. It is excellent, compact, and can flexibly respond to changes in the solenoid valve configuration.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIG. 1, 1 is a programmable controller, 2
3 is a transmission cable as a serial signal means, and 4 is a transmission cable for converting and transmitting a predetermined number of parallel output signals into serial signals. Serial-to-parallel converting means (hereinafter referred to as a receiving unit) for converting into the original parallel signal, 5 is a multiple manifold, and 6 is a solenoid valve.

In FIGS. 2(a) and 2(b), 7 is a space inevitably created by connecting the manifold 5 and the solenoid valve 6. As shown in FIGS. 1 and 3, the receiving unit 4 is housed in this space 7, and is directly connected to the solenoid valve 6 by a connector. This eliminates the need for all wiring using electric wires, making it compact and flexibly responding to changes in the configuration of the solenoid valve.

FIG. 3 shows the specific configuration of this solenoid valve wiring-saving system.

In FIG. 3, 8 is a connector for connecting the receiving unit 4 and the solenoid valve 6, 9 is a connector for connecting the receiving unit 4 and the transmitting unit 2 by the transmission cable 3, and 10 is a connector for connecting the receiving unit 4 and the solenoid valve 6.
When you want to further increase the number of solenoid valves 6 (in the example in Figure 3, the number of solenoid valves is 8, but when you want to control 9 or more), you can add more receiving units 4 to increase the number of solenoid valves 6 (in reality). is limited by the 110 points of the PC and the current capacity limit,
11 is a cover for protecting the receiving unit 4.

The operation of the solenoid valve wiring saving system configured as above will be described below.

First, a serial signal transmitted from the transmitting unit 2 in FIG. 1 is guided to the receiving connector 9 via the transmission cable 3. The serial signal guided to the receiving unit 4 is converted into a parallel signal before being transferred according to rules established within the receiving unit 4. The converted parallel signal is amplified within the receiving unit 4 and output to a solenoid valve connecting connector 8 fixed to the upper part of the printed circuit board of the receiving unit 4.

The receiving unit 4 is not limited to printed circuit boards, but also hybrid I.
It goes without saying that similar effects can be obtained with other circuit configurations such as C. The solenoid valve connecting connector 8 is placed on the receiving unit 4 at the position where the solenoid valve 6 is attached, and by attaching the solenoid valve 6 to the manifold 5,
Moreover, they are mechanically and electrically connected in an instant. The solenoid valve connecting connector 8 can be used to connect a double solenoid valve by connecting two parallel output signals using a connector with three or more poles, but when connecting a single solenoid valve, two of the poles ( Parallel output signal 2
You can use one of the books. By constantly assigning two outputs to one solenoid valve in this way, the configuration of the solenoid valve (double or single) can be freely changed.

As shown in Figure 3 (since the receiving unit 4 is assembled in a configuration in which it is built into the lower manifold 5 of the solenoid valve 6, the external dimensions after assembly are almost the same as those in a configuration consisting of a normal manifold and a solenoid valve). This makes it possible to save space for solenoid valve equipment.

In the above embodiment, the receiving unit 4 is housed in the manifold 5 through the cover 11, but as shown in FIG. Not only can the same effects as in the example be obtained, but also the receiving unit 4 can be easily installed and removed after assembling the solenoid valve, improving maintainability.

Effects of the Invention As described above, the present invention improves wiring assembly man-hours and appearance by arranging the serial conversion means in the space inevitably created by combining the solenoid valve and the manifold, and connecting the solenoid valve with a connector. A wiring-saving system that is compact and can flexibly respond to changes in the configuration of solenoid valves can be realized, and its practical effects are significant.
