Abstract

PURPOSE:To obtain a device which controls the inversion of an output through the operation of one light illumination type push button and does not change in output state even when the push button is pressed in a power-off state, by performing the inversion control under which a keep relay is energized and reset repeatedly. CONSTITUTION:One switch, two relays, and one keep relay are provided for the inversion control where the keep relay is operated and reset repeatedly every time when the switch is turned on or off while the keep relay is reset. For example, when the switch 1 is turned on while the keep relay 3 is reset, a relay 6 is energized to put the keep relay 3 in operation. When the switch 1 is operated at said point of time, the relay 6 is turned off and when the switch 1 is turned on again successively, a relay 7 operates to reset the keep relay 3. Then, lamps 4 and 5 are turned on the contact of the keep relay 3 to display an output state.

SUMMARY OF THE INVENTION Aiming to provide an unchanging sequence itj control device, the present invention consists of one switch, two relays and one keep relay, the switch is activated and the keep relay is in the reset state. By operating the switch, the relay that is not self-operating among the two operates when it is not activated, and the self-holding relay drives the operating coil of the keep relay,
When the keep relay is in operation, the above relay operates when the switch is not in operation, and the other self-holding relay resets the keep relay, so the keep relay operates and resets each time the switch is turned on and off. It is characterized by performing reversal control that repeats.

Assuming that the keep relay 3 is currently in the reset state in FIG. The coil of the relay 6 is excited through the b contact 3hl and the b contact 7bl of the relay 7, and the relay 6 operates, and the a contact 6al of the relay 6 is self-holding. When the relay 6 operates, the a slave point 6a2 of the relay 6 turns on, and the operating coil 30 of the keep relay 3 is energized.
works. When keep relay 3 operates, keep relay 3's b contact 3b1 turns off, but relay 6's a
Since a self-hold circuit is formed by the contact 6al, the relay 6 is in the on state up to 1'. When the keep relay 3 operates, the a contact 3al is turned on, but since the relay 6 is self-holding, the b contact 6bl of the relay 6 is turned off, and the relay 7 is not activated.

ルドがかかる。If the switch 1 is turned off at this point, the relay 6 will be in a non-excited, shut-off state. Therefore, the a contact 6a2 of the relay 6 connected to the operating coil 30 of the keep relay 3 is also turned off, but the operating state is maintained because it is a keep relay. When the switch 1 is turned on again while the keep relay 3 is in operation, the relay 7 is energized via the a contact 3al of the keep relay 3 and the b contact 6bl of the relay 6, and the relay 7 is activated. Self-hold is applied at 7al.

When the keep relay 3 is reset, the a contact 3ai of the keep relay 3 is turned off, but since a self-hold circuit is formed by the afd point 7al of the relay 7, the relay 7 is connected to the on state. The output status is 8 contacts 332, b of keep relay 3.
The display is performed by lighting the lamps 4 and 5 through the contact 3b2.

−３とも現状維持となる。By combining the relay hold circuit and the keep relay circuit as described above, it is possible to perform inversion control with a single switch, but this can be done using control that takes advantage of the non-zero operation time of the relay, as shown in Figure 3. The operation will be explained using the time chart. Here, we assume that the relays are standard, and the contacts of relays 6 and 7 are on at 20m5 and off at 10m5, and the contacts of keep relay 3 are both on and off at 20m5. do. In other words, even if the operating time changes a little, as long as it is not zero, this circuit will normally produce HIij1. If the switch is turned on when the keep relay is on, 20.
At 7718, the contact point of v-, 6 turns on, the boiled fish of relay 6 turns off, and after 20n1S, the contact force of keep relay 3 becomes 9.
Operate. In other words, in Figure 2, relay 6 operates and 7
After a self-hold circuit is formed at the suction point 6ai of 3, the l) contact of the keep relay 3: 3! y 1 turns off 0
When the switch 1 is then turned off, the contact point of the relay 6 is turned off, but at this point, both the relay 7 and the relay 3 remain in their current state.

Effects of the Invention -1+'As described above, if this device is used, it is possible to reduce the size of the operation panel because it eliminates the inversion operation of the -C output with a single switch, and it is also possible to reduce the size of the operation panel compared to conventional machines. The shortcoming of the push-button switch, which reverses automatically, is to prevent erroneous operation at the time of Ichihara's disconnection.
