Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an operating mechanism of a panel-mounted controller.

[Conventional technology]

FIG. 4 is a partially cutaway perspective view showing an example of a conventional panel mounting type controller. In the figure, 1 is an instrument case, 2 is a panel mounting surface operating section, and 3 is an internal unit provided with this panel mounting surface operating section 2. Thus, the instrument case 1 can be pulled out and stored. 4 is a process value display, 5 is a set value display, 6 is a manipulated variable display, 7 is an operation switch,
The process value display 4, the set value display 5, the manipulated variable display 6 and the operation switch 7 are incorporated in the panel mounting surface operation unit 2, respectively. A printed circuit board 8 for controlling the main body is provided in the internal unit 3. Reference numeral 9 is a numerical display for displaying numerical data for program processing, 10 is a numerical operation switch for reading and writing numerical data, and these numerical display 9 and numerical operation switch 10 are respectively provided in the internal unit 3. It is provided on the side surface and is connected to the main body control printed circuit board 8.

Next, the operation will be described.

A normal operation is performed by the panel mounting surface operation unit 2, and the set value display 5 and the manipulated variable display 6 are changed by the operation switch 7 while observing the process value display 4. When changing the adjustment method or reading or writing numerical data during program processing, the internal unit 3 is pulled out from the instrument case 1, and the numerical display 9 and numerical operation switch connected to the main body control printed circuit board 8 are used. 10 and 10 are operated from the side surface of the internal unit 3.

[Problems to be solved by the invention]

Since the conventional panel-mounted controller is configured as described above, when the internal unit 3 is pulled out, it is necessary to operate while looking at the front panel and the side surface, and the operation unit and the display unit are on the same surface. There is a problem that it is difficult to operate because it is not. Further, since the main body control printed circuit board 8 that is not directly related to the adjustment, reading, and writing operations is pulled out together when the internal unit 3 is pulled out, there is a problem that the internal unit becomes large and the weight becomes large.

The present invention has been made to solve the above-mentioned problems, and makes it easy to change the adjustment method and read or write numerical data in the middle of program processing, and at the same time reduce the size and weight of the internal unit. The purpose is to obtain a simplified panel-mounted controller.

[Means for solving problems]

The panel-mounted controller according to the present invention has a structure in which the side operation portion of the internal unit is rotatable so as to be a surface substantially parallel to the panel attachment surface operation portion, and the main body control printed circuit board is not incorporated in the internal unit. It is structured.

[Action]

The side operation part in this invention is rotatably supported by a hinge mechanism, and can be operated by rotating the side operation part on the same surface as the panel mounting surface.

[Example of device]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an embodiment of the present invention,
In FIG. 1, the same or equivalent components as those in FIG. 4 are designated by the same reference numerals, and duplicate description will be omitted. In FIG. 1, reference numeral 11 is a side surface operation section rotatably supported by a panel mounting surface operation section 2 by a hinge pin 13, and numeral 12 is a numerical display 9 for displaying numerical data for program processing and reading of the numerical data. A side operation unit printed circuit board to which a numerical operation switch 10 for writing and writing is connected.
Installed on. The side operating portion printed circuit board 12 is connected to the main body control printed circuit board 8 provided in the instrument case 1. It is needless to say that a mechanism (not shown) for locking the side surface operating part 11 in a state where the side surface operating part 11 is rotated so as to be substantially parallel to the panel mounting surface operating part 2 is provided.

Next, the operation will be described.

The normal operation is performed by the panel mounting surface operation unit 2, and the set value display 5 and the manipulated variable display 6 are changed by the operation switch 7 while observing the process value display 4. When changing the adjustment method or reading or writing numerical data during program processing, the internal unit 3 from the instrument case 1
Is pulled out to the panel surface side, the side surface operating portion 11 mounted on the side surface of the internal unit 3 is rotated about 90 ° about the hinge pin 13 so that the side surface operating portion 11 is located on a surface parallel to the panel mounting surface operating portion 2, and the process value While watching the display 4, the set value display 5, the manipulated variable display 6 and the numerical display 9, the numerical operation switch 10 is operated.

In the above embodiment, the hinge pin 13 allows the internal unit 3
And the side operating part 11 are movably supported, but the side operating part 11 is also located substantially on the same plane as the panel mounting surface operating part 2 by the link arm 14 shown in FIG. 2 and the spring 15 shown in FIG. May be rotated.

In this case, it is a matter of course that a configuration is provided in which the side surface operating portion 11 is locked at that position when the side surface operating portion 11 is pulled out so as to be substantially parallel to the panel mounting surface operating portion 2. Further, in the above-mentioned embodiment, the controller having the vertically long display attached to the panel mounting surface operation unit 2 has been described, but the display may be a controller of any display / operation mode such as a numerical display, The same effect as that of the above embodiment is obtained.

[Effect of device]

As described above, according to the present invention, the side operation unit has the side operation unit printed circuit board in which the numerical display unit and each of the numerical operation switches are electrically connected to the side unit of the internal unit that can be pulled out from the instrument case. Since the portion is configured to be pivotally supported so as to be openable and closable in a folding position into the internal unit and in a deployed position substantially parallel to the panel mounting surface operating portion, after pulling out the internal unit from the instrument case, By opening and rotating the side surface operating portion from the side surface portion of the internal unit, the side surface operating portion can be deployed at a position substantially parallel to the panel mounting surface operating portion, and therefore,
While facing the panel mounting surface operating section, the numerical display, numerical operation switch, etc. of the side operating section can be easily and conveniently operated, and the operability is improved. Further, since the printed circuit board for controlling the main body is attached to the instrument case side, there is an effect that the internal unit can be downsized.
