본 고안은 생산라인에서 콤베어 시스템등을 채용하여 자동적으로 시퀀스 동작을 수행하는데 필요로 하는 신호출력을 온, 오프 제어하는 일방향성 리미트 스위치에 있어, 일반적인 리미트스위치 또는 마이크로 스위치를 사용하여서도 일방향성 리미트(One Way Limit) 스위치의 기능을 수행할 수 있도록한 스위치회로에 관한 것이다.The present invention is a one-way limit switch that controls the signal output required to automatically perform the sequence operation by adopting a conveyor system in the production line, and it is one-way even using a general limit switch or a micro switch. The present invention relates to a switch circuit capable of performing a function of a limit switch.

종래에는 제1도에 도시한 바와같이 일방향성 리미트스위치(SW1)의 손잡이를 시계방향으로 동작시키게 되면 릴레이(Xo)가 구동되어 그의 a접점(Xo1)접속되므로서 신호를 출력하게 되고, 한편 스위치(SW1)를 반시계 방향으로 동작시키게 되면 릴레이(Xo)가 구동되지 않아 그의 a접점(Xo1)이 개방되므로서 신호출력이 나타나지 않도록 구성되어져 있어 사용중 일방향성 리미트 스위치의 고장으로 인하여 이를 교환해야만할 경우에는 고가이며 부품수배가 용이하지 못하여 장시간동안 고장난 상태로 방치하여야 하는 문제점이 있었다.Conventionally, as shown in FIG. 1 , when the knob of the one-way limit switch SW 1 is operated in the clockwise direction, the relay Xo is driven to output a signal by being connected to the a contact Xo 1 thereof . On the other hand, when the switch SW 1 is operated in the counterclockwise direction, the relay Xo is not driven so that the contact point Xo 1 is opened so that the signal output does not appear. If it has to be replaced, there is a problem in that it is expensive and the arrangement of parts is not easy, so it must be left in a broken state for a long time.

본 고안은 이와같은 점을 감안하여 일반적인 리미트스위치나 마이크로 스위치를 사용하여도 손쉽게 일방향성 리미트스위치와 동일한 기능을 수 행할수 있도록 하여 상기한 종래의 문제점을 해결할 수가 있는 것으로, 이하첨부 도면에 의하여 상술하면 다음과 같다.The present invention can solve the above-mentioned problems by allowing the same function as the one-way limit switch to be easily performed even by using a general limit switch or a micro switch. Is as follows.

제2도에서와 같이 일반적인 리미트스위치 또는 마이크로 스위치(SW2)에 각각 병렬접속된 릴레이(R3)의 b접점(3b1), 릴레이(R1)의 a접점(1a1)과 릴레이(R3)의 a접점(3a1), 릴레이(R2)의 a접점(2a1)를 각각 릴레이(R2)의 b접점(2b1)과 릴레이(R1)의 b접점(1b1)을 통하여 릴레이(R1), (R2)에 각각 연결시키고, 병렬접속된 릴레이(R1)의 a접점(1a2), 릴레이(R3)의 a접점(3a2)을 릴레이(R2)의 b접점(2b2)과 직렬 연결하여 릴레이(R3)에 연결시키며, 릴레이(R1)의 a접점(1a3)을 릴레이(Xo)에 연결시켜서 그의 a접점(Xo1)에서 신호 출력이 나타나도록 연결구성한다.The typical limit switch or micro-switch (SW 2), each connected in parallel to the relay (R 3) of the b-contact (3b 1), the relay (R 1) of a contact (1a 1) and relays (R in, as shown in Figure 2 3 ) contact a (3a 1 ) of the relay (R 2 ), contact a (2a 1 ) of the relay (R 2 ) and contact b (2b 1 ) of the relay (R 2 ) and contact b (1b 1 ) of the relay (R 1 ), respectively. through the relay (R 1), each connected to a and (R 2), the parallel connection of the relay (R 1) of a contact (1a 2), the relay (R 3) of a contact (3a 2) a relay (R 2) Connects to relay (R 3 ) in series with contact b (2b 2 ) of, connects contact a (1a 3 ) of relay (R 1 ) to relay (Xo) and outputs the signal at contact a (Xo 1 ). Configure the connection so that it appears.

미설명 부호 a접점을 릴레이 구동시온되고, b접점을 릴레이 구동시오프되는 접점이다.Reference numeral a indicates that the contact a is turned on when the relay is driven, and the contact b is turned off when the relay is driven.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

제2도에서 일반적인 리미트스위치 또는 마이크로스위치(SW2)의 손잡이를 시계방향으로 동작시키면 릴레이(R3), (R2)는 구동상태가 아니므로 그의 b접점(3b1, 2b1)은 접속 상태이어서 릴레이(R1)가 구동하게 되어 그의 a접점(1a1)에 의하여 자기유지되고,In FIG. 2 , when the knob of the general limit switch or the micro switch SW 2 is operated in the clockwise direction, the relays R 3 and R 2 are not driven, and thus their contact b 3b 1 and 2b 1 are connected. State that the relay R 1 is driven and is self-maintained by its a contact 1a 1 ,

한편 a접점(1a3)도 접속되므로 인하여 릴레이(Xo)를 구동시켜 그의 a접점(Xo1)이 온 상태로 되면 신호출력이 나타나게 되며 릴레이(R3)는 a접점(3a2)에 의하여 자기 유지상태가 된다.On the other hand, since contact a (1a 3 ) is also connected, drive relay (Xo) and its a contact (Xo 1 ) is turned on, signal output appears and relay (R 3 ) is a magnetic contact by contact a (3a 2 ). It becomes a maintenance state.

한편 리미트스위치 또는 마이크로스위치(SW2)를 반시계 방향으로 동작시키게 되면 릴레이(R3)는 구동상태이므로 그의 a접점(3a1)은 온 상태이어서 릴레이(R2)를 구동시키고, 그의 b접점(3b1)은 오프되어 릴레이(R1)를 오프시키므로 그의 a접점(1a3)도 오프되어 릴레이(Xo)가 오프상태가 되므로 신호출력이 나타나지 않게 된다.On the other hand, when the limit switch or the micro switch SW 2 is operated in the counterclockwise direction, the relay R 3 is in a driving state, and thus, the contact a 3a 1 thereof is in an on state to drive the relay R 2 and the contact b thereof. Since 3b 1 is turned off to turn off the relay R 1 , the a contact 1a 3 is also turned off so that the relay Xo is turned off so that the signal output does not appear.

이때 릴레이(R2)가 온 상태이므로 그의 b접점(2b2)에 의해 릴레이(R3)가 오프되며 결국 모든 릴레이는 초기상태인 오프상태로 된다.At this time, since the relay R 2 is on, the relay R 3 is turned off by the b contact 2b 2 , and eventually all relays are turned off.

이상에서와 같이 본 고안은 공지한 리미트스위치 또는 마이크로스위치를 사용하여도 고가이며 수배가 용이하지 못한 일방향성 리미트 스위치의 역할을 수행할 수 있도록 하여 사용중 고장으로 인한 종래의 결점을 손쉽게 해결할 수가 있고, 또한 원가 절감의 효과도 꾀할수가 있는 것이다.As described above, the present invention makes it possible to perform the role of a one-way limit switch that is expensive and not easy to be used even by using a known limit switch or a micro switch, and thus can easily solve the conventional defects caused by a failure in use. In addition, cost savings can be achieved.
