Description

[Detailed explanation of the invention] [Industrial application field] Control panels and display panels are called mosaic panels, and as shown in Fig. 9, individual squares of a panel frame B having a large number of squares A and A are used. Attach tile C to A and create the board surface.
There are known devices that constitute the display surface.

The present invention relates to a display device in which three displays can be freely changed in such a mosaic panel.

[Conventional technology]

As a mosaic panel that changes the display, it is known that a large number of light emitting diodes are incorporated inside the tile to display the operating status of equipment and the like by changing colors. However, for example, the lines of piping and wiring connecting equipment were usually simply marked with paint on the surface of the mosaic panel and could not be easily changed.

In addition, as a method to change the display according to the situation, including equipment display and line display, a cathode ray tube is installed in the panel, and changes in the operating status of lines and equipment are displayed in images using colors, shapes, flashes, etc. This is also being done. In this case, since the size of the cathode ray tube is limited, a method is used in which the entire flow is displayed on a mosaic panel and only a portion of it is displayed on the cathode ray tube.

As a general method of changing the display,
As shown in No. 115511, an electromagnet and a ferrite magnet with different markings on two surfaces are combined,
A method is known in which the display is changed by inverting the polarity of an electromagnet.

[Problem that the invention attempts to solve]

Conventional mosaic panels that only change the display of equipment according to operating conditions and do not change the display of lines have a weak ability to alert operators and supervisors. In addition, when using a mosaic panel display and a cathode ray tube display together,
The disadvantage is that each display gives a different impression, making it easy to misunderstand.

It is conceivable that the line display could be illuminated with light emitting diodes, similar to the display of equipment, but
It is difficult to provide a large number of illumination means capable of changing as many as three types of display at a high density. Even if possible, this display device would be expensive and
Power consumption is also large, and other problems such as heat generation due to internal resistance of light emitting diodes and the like arise.

A reversible type that combines an electromagnet and a ferrite magnet has a simple structure and reliable operation, but
The conventional display cannot perform three types of display changes.

In view of the above-mentioned drawbacks of the prior art, the present invention has devised a display device for a mosaic panel that has a relatively simple structure and can perform three types of display changes.

[Means for solving problems]

As shown in Figure 1, a shaft 3 parallel to the surface of the tile body is provided behind the window 2 provided on the surface (front) of the tile body, and the tile rotates within a certain angle range around this shaft 3. , an inverter 4 is provided in which one of three display surfaces 4a, 4b, 4c faces the window 2 depending on the rotational position. In order to select and display a desired display surface among the three display surfaces of the inverter, two drive sections, the first drive section 5 and the second drive section 8, are installed at different positions on the shaft 3. establish.

The first drive unit 5 is fixed to the rear of the reversing body 4, includes an electromagnet 6 whose polarity can be changed with one end of the magnetic core facing the direction of the reversing body 4, and is fixed to the reversing body 4 facing the electromagnet 6, and is fixed to the reversing body 4 in the direction of rotation. It is composed of a ferrite magnet 7 having magnetic poles at both ends.

On the other hand, the second drive section 8 is composed of an electromagnet 9 fixed behind the reversing body 4 and a ferrite magnet 10 fixed to the reversing body 4, and by exciting the electromagnet 9, the reversing body 4 Display surface 4b at the intermediate position of
Assume that the ferrite magnet 10 is attracted to a position facing the window 2.

[Effect]

In the first drive unit 5, when a current in a certain direction is applied to the electromagnet 6, the magnetic core facing the inverter is excited to either N or S, and attracts one pole of the ferrite magnet 7 in front of the magnetic core. The other pole is repulsed to generate rotational force in the inverter 4, and the display surface 4
Either a or 4c is displayed on window 2 of the tile body. When the polarity of the electromagnet 6 is changed, that is, the direction of energization is changed, the direction of attraction and repulsion of the ferrite magnet 7 becomes opposite to that in the above case, and the inverting body rotates in the opposite direction, causing either the display surface 4a or 4c to move toward the other side. is displayed in window 2 of the tile body. In any of these cases, when the current to the electromagnet is cut off after changing the display, the magnetic force of the ferrite magnet attracts the magnetic core of the electromagnet, and the changed display is maintained as it is.

When the electromagnet 9 of the second drive section is excited with the power supply to the first drive section stopped, the electromagnet 9 and the ferrite magnet 10 are attracted, and the reversing body 4 is moved to the intermediate position of rotation, that is, the display surface 4b is moved to the window 2. and then stop. Thereafter, when the current of the electromagnet is cut off, the display on the display surface 4b is maintained by the magnetic force of the ferrite magnet 10.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a front view, and FIG. 2 is a sectional view taken along the line -- in FIG. 1. A rectangular window 2 is provided on the surface (front) of the square tile body 1, and a horizontal axis 3 is provided behind it, and the axis 3 has a fixed angle around this, a range of 120 degrees on the drawing. An inverter 4 is provided which can rotate to select any one of the three display surfaces 4a, 4b, and 4c to face the window 2. In other words, the inverter 4 has a hexagonal tube divided into two parts, and the three surfaces are used as display surfaces 4a to 4c.
The display surface can be changed by rotating every 60 degrees. However, the shape of the reversing body 4 (the angle between the surfaces) can be changed to change the display by changing the rotation angle of less than 180 degrees.

Two drive sections are provided to change the display surface, of which the first drive section 5 selects the display surfaces 4a and 4c, which are rotational positions at both ends of the reversing body 4, and the second drive section Section 8 is for selecting the display surface 4b.

As shown in FIGS. 3 to 5, the first drive unit 5 has a polarity-changeable electromagnet 6 with one end of the magnetic core provided behind the reversal body 4 facing the direction of the reversal body, and the electromagnet 6 faces the electromagnet 6. ferrite magnets 7 (permanent magnets) that are fixed to the inverter 4 and have magnetic poles at both ends in the rotating direction, that is, are arranged vertically. For example, as shown in FIG.
The magnetic core 6a and the ferrite magnet 7 directly face each other, and by energizing the electromagnet 6, one magnetic pole of the ferrite magnet 7 is attracted and the other is repelled, thereby rotating the inverting body. By changing the polarity of the electromagnet 6, one of the display surfaces 4a and 4c of the inverter is selected as shown in FIGS. 4 and 5.

As shown in FIG. 2, the ferrite magnet 10 constituting the second drive unit 8 is fixed to the inverter 4 and has magnetic poles at both ends in the rotation direction, and the electromagnet 9 connects both poles of the magnetic core to the ferrite magnet 10. It is placed close to both poles of. Display surface 4a or 4c is window 2
When the electromagnet 9 is excited while facing the ferrite magnet 10, the electromagnet 9 attracts the ferrite magnet 10 and the inverting body 4
is rotated to a position where the intermediate display surface 4b faces the window 2. In other words, the electromagnet 9 has a constant polarity and does not change its polarity like the electromagnet 6 of the first driving section. In the illustrated embodiment, as can be understood from FIGS. 2 and 8, the overall shape of the magnetic core is approximately U-shaped,
A ferrite magnet 10 is positioned between the two poles. Although the ferrite magnet 10 has an arcuate shape, this is to more accurately determine the stopping position of the display surface 4b, and other shapes may also be used.

In the drawing, reference numerals 11 and 12 are stoppers of the reversing body, which prevent the reversing body from over-rotating when displaying on the display surfaces 4a and 4c.

Next, the order of operation for changing the display is shown in Figures 6 to 8.
This will be explained based on the diagram.

FIG. 6a shows the display state of the display surface 4a, when the R and C terminals of the electromagnet 6 are energized, the ferrite magnet 7
When the magnetic core 6a of the electromagnet 6 facing the ferrite magnet 6 is excited to the N pole, the N pole of the ferrite magnet 7 is repelled and the S pole is attracted, and as a result, rotational force is generated in the inverter 4, and the state shown in FIG. 6b is passed. Then, it stops in the display state of the display surface 4c shown in FIG. 6c.

At this time, when the electromagnet 6 is de-energized and excitation is stopped, the S pole of the ferrite magnet attracts the magnetic core 6a to maintain the state shown in FIG. 6c.

The display change from the display surface 4a to 4c is performed in a completely reverse order to the above case.

In the display state of the display surface 4c shown in FIG. 7a, the C and G terminals of the electromagnet 6 are energized to excite the magnetic core 6a to the S pole. Then, a rotating force is generated in the opposite direction to that shown in FIG. 6, and the device passes through the state shown in FIG. 7b and stops in the state shown in FIG. 7c. When the power supply is stopped in this state, the N pole of the ferrite magnet 7 attracts the magnetic core 6a of the electromagnet 6, and the display state of the display surface 4c shown in FIG. 7c is maintained.

The display change from the display surface 4a or 4c to the display surface 4b is performed by exciting the electromagnet 9 of the second drive section 8. FIG. 8a shows the display state of the display surface 4a. When the electromagnet 9 is energized and N and S poles are generated at both ends thereof, the S and S poles of the ferrite magnet 10 and S poles of the electromagnet 9 and S poles of the ferrite magnet 10 and The N pole is attracted and generates rotational force, and the display surface 4 shown in FIG. 8b
It balances and stops at the display state b. If the electromagnet 9 is de-energized in this state, the ferrite magnet 10 will be
The pole and south pole each attract opposite ends of the electromagnet's magnetic core and maintain that state.

At this time, since the center of the ferrite magnet 7 of the first drive section 5 directly faces the magnetic core 6a of the electromagnet 6, no turning force is generated, and the display surface 4b is generated by the magnetic force of the ferrite magnet 10 of the second drive section 8. display is maintained.

When displaying lines of wiring or piping as shown in FIG. 9, the display devices of the present invention are arranged as adjacent blocks.

[Effect of idea]

According to the three-sided reversing display device for a mosaic panel of the present invention, the display device that can change the display on three sides has a relatively simple structure and the entire device is small compared to the display size, and the blocks of the mosaic panel can be It can be accommodated in a limited space. Also,
The display screen can be changed only by excitation of the electromagnet for a short time, and after the excitation is cut off, the previous display is reliably maintained, and there is no risk of display errors. This means that power consumption is lower than that of displays using light emitting diodes, and there is no problem of heat generation. Therefore, the present invention is effective when displaying a variable display using a large number of devices, such as a pipeline monitoring control panel.

Note that in a display device using a light emitting diode, the colors that can be used are limited, but in the present invention, any color or pattern can be displayed on each of the three display surfaces of the inverter.
