본 고안은 유압이나 공압을 작동원으로 이용하여 제작되는 모든 기계장치에서 기계의 작동용으로 사용되는 전자식 솔레노이드 밸브 코일의 단선 유무를 직접 육안으로 확인할 수 있도록 한 검출회로에 관한 것이다.The present invention relates to a detection circuit that enables the naked eye to directly check the disconnection of the electronic solenoid valve coil used for the operation of the machine in all machinery manufactured by using hydraulic pressure or pneumatic pressure.

종래에 다수개의 전자식 솔레노이드 밸브를 설착하여 기계적인 작동을 시키는 경우 기계동작의 불량 원인을 규명하는 데는 별도의 계측기(tester)등을 사용하여 각각의 솔레노이드 밸브 코일을 첵크하여 단선된 솔레노이드 밸브 코일을 인지하여 이를 보수토록 하였으나 이 경우 첵크시 많은 시간이 소요되었고 또한 그 과정이 매우 번거러웠을 뿐만 아니라 보수시까지는 장시간 기계의 정지가 불가피하여 생산 능률이 저하되는 등의 많은 문제점이 있었다.Conventionally, when a plurality of electronic solenoid valves are installed and mechanically operated, the solenoid valve coils are identified by checking each solenoid valve coil using a separate tester, etc. However, in this case, it took a lot of time during the check, and the process was very cumbersome, and there was a lot of problems such as the inevitability of the machine for a long time until the maintenance was inevitable.

본 고안은 전술한 바와 같은 종래의 문제점을 착안하여 저항, 릴레이, 네온램프 및 푸쉬보턴 스위치와 선택용 토글 스위치로서 간단한 검출회로를 구성하여 용이하게 단선 유무를 확인할 수 있도록 안출한 것인바, 본 고안의 요지를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is conceived to make it easy to check the disconnection by configuring a simple detection circuit as a resistor, a relay, a neon lamp and a push button switch and a toggle switch for selection by considering the conventional problems as described above. The gist of the present invention will be described in detail with reference to the accompanying drawings.

교류 전원 입력단(T2, T3)에 토글 스위치(SW1)와 그의 "b"접점(SW1b)을 각각 병렬 연결하되, 입력단(T1, T3)에는 솔레노이드 밸브(SOL1)와 그의 동작 신호접점(SR1)을 직렬 연결하고 그 사이에 릴레이(Ry2)의 "a"접점(Ry2a1)을 병렬 연결하여 입력단(T1, T2)에 직렬 연결되는 네온램프(NL1)와 한류 저항(R1) 및 릴레이(Ry2)의 "a"접점(Ry1a1)사이에 연결하여서 단위 검출회로(A)를 구성하며, 또한 입력단(T1, T3)에 솔레노이드 밸브(SOL2)와 그의 동작 신호접점(SR2)을 직렬 연결하고 그 사이에 릴레이(Ry2)의 "a"접점(Ry2a2)을 병렬 연결하여 입력단(T1, T2)사이에 직렬 연결되는 네온램프(NL2)와 한류 저항(R2) 및 릴레이(Ry2)의 접점(Ry1a2) 사이에 연결하여서 단위 검출회로(An)을 구성하며, 한편 입력단(T1, T2)에 램프 테스트 푸쉬버튼 스위치(BSW1)와 단선검출 푸쉬버튼 스위치(BSW2)를 직렬 연결하되 그의 "b"접점(BSW1b, BSW2b)을 직렬 연결하여서 인터록 회로로 연결되게 하고 그에 릴레이(Ry1, Ry2)를 각각 연결하여서 구성한다.Toggle switch (SW 1 ) and its "b" contact (SW 1 b) are connected in parallel to AC power input (T 2 , T 3 ), but solenoid valve (SOL 1 ) is connected to input (T 1 , T 3 ). Neon lamps connected in series to the input terminals T 1 and T 2 by connecting their operating signal contacts SR 1 in series, and connecting the “a” contacts Ry 2 a 1 of the relay Ry 2 in parallel therebetween. NL 1 ) is connected between the current-limiting resistor R 1 and the “a” contact (Ry 1 a 1 ) of the relay Ry 2 to form a unit detection circuit A, and also the input terminals T 1 , T 3 . a solenoid valve (SOL 2) and connected in series to its operation signal contact (SR 2) and a parallel connection to "a" contact point (Ry 2 a 2) of the relay (Ry 2) between the input terminal (T 1, T 2 ) Is connected between the neon lamp NL 2 connected in series and the current-limiting resistor R 2 and the contact Ry 1 a 2 of the relay Ry 2 to form a unit detection circuit An, while Lamp test pushbutton switch (BSW 1 ) to T 1 , T 2 ) Connect the disconnection detection pushbutton switch (BSW 2 ) in series, and connect their "b" contacts in series (BSW 1 b, BSW 2 b) to the interlock circuit, and connect the relays (Ry 1 and Ry 2 ) to each other. To configure.

이와 같이 구성된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

먼저 솔레노이드 밸브(SV1)(SVn) 코일의 단선 여부를 확인하기 전에 네온 램프(NL1)(NL2)가 점등되는지의 여부를 확인키 위하여는 토글 스위치(SW1)를 "on"하면 마그네트 스타트 인터록 회로에 의하여 "b"접점(SW1b)은 "OFF"가 되기 때문에 솔레노이드 밸브(SOL1, SOL2)를 구동시키는 신호 접점(SR1)(SR2)도 "OFF"된다.To check whether the neon lamp (NL 1 ) (NL 2 ) is lit before checking whether the solenoid valve (SV 1 ) (SVn) coil is disconnected, turn on the toggle switch (SW 1 ) and turn on the magnet. Since the "b" contact SW 1 b becomes "OFF" by the start interlock circuit, the signal contact SR 1 (SR 2 ) for driving the solenoid valves SOL 1 , SOL 2 is also "OFF".

이때 램프 테스트 저령용 푸쉬보턴 스위치(BSW1)을 "on"하면 인터록회로 동작에 의해 "b"접점(BSW1b)은 개방되어 릴레이(Ry2)는 록(LOCK)되어서 동작되지 않음과 동시에 단선 검출 푸쉬버튼 스위치(BSW2)가 접속되면서 릴레이(Ry1)는 여자되어 그 "a"접점(Ry1a1)(Ry1a2)이 "온"되므로 입력단(T2)의 전원이 토글 스위치(SW2)와 네온램프(NL1)(NL2) 및 저항(R1)(R2)과 접점(Ry1a1)(Ry1a2)으로 흐르게 되어 각 네온램프(NL1)(NL2)가 점등됨으로서 테스트하게 된다.At this time, when the lamp test control pushbutton switch BSW 1 is "on", the "b" contact BSW 1 b is opened by the interlock circuit operation, and the relay Ry 2 is locked and is not operated. When disconnection detection pushbutton switch BSW 2 is connected, relay Ry 1 is excited and its "a" contact Ry 1 a1 (Ry 1 a2) is "on", so the power of input terminal T 2 is toggle switch. (SW 2 ) and neon lamps (NL 1 ) (NL 2 ) and resistors (R 1 ) (R 2 ) and contacts (Ry 1 a 1 ) (Ry 1 a 2 ) to flow through each neon lamp (NL 1 ) ( NL 2 ) lights up to test.

이와 같은 과정의 램프 테스트로 네온램프(NL1)(NL2)에 이상이 없을 때는 솔레노이드 밸브 코일의 단선 검출지령 신호인 푸쉬보턴 스위치(BSW2)를 누르게 되면 인터록 회로의 동작에 의해 푸쉬버튼 스위치(BSW1)(BSW2)는 개방되어지고 그의 "b"접점(BSW2bb)(BSW1b)이 접속됨으로써 릴레이(Ry2)은 록(LOCK)되어 동작을 하지 않게 되며 릴레이(Ry1)는 여자되어 그 "a"접점(Ry2a1)(Ry2a2)이 단락되어 네온램프(NL1)(NL2)와 "a"접점(Ry2a1)(Ry2a2)과 솔레노이드 밸브(SOL1)(SOL2)의 회로가 성립하여 네온램프(NL1)(NL2)가 점등되는데 만약 솔레노이드 밸브(SOL1)(SOL2)의 코일이 단선되었다면 그 표시램프(NL1)(NL2)가 점등되지 않기 때문에 이를 즉시 육안으로 확인할 수가 있는 것이다.When the neon lamp NL 1 (NL 2 ) has no problem with the lamp test in this process, when the push button switch (BSW 2 ), which is the disconnection detection command signal of the solenoid valve coil, is pressed, the push button switch is activated by the operation of the interlock circuit. (BSW 1 ) (BSW 2 ) is opened and its "b" contact (BSW 2 bb) (BSW 1 b) is connected so that relay (Ry 2 ) is locked and does not work and relay (Ry 1) ) Is excited and its "a" contact (Ry2a1) (Ry2a2) is short-circuited so that neon lamp NL 1 (NL 2 ) and "a" contact (Ry2a1) (Ry2a2) and solenoid valve (SOL 1 ) (SOL 2 ) Neon lamp (NL 1 ) (NL 2 ) is turned on because the circuit of is established. If the coil of solenoid valve (SOL 1 ) (SOL 2 ) is disconnected, the indicator lamp (NL 1 ) (NL 2 ) is not lit. This can be confirmed immediately with the naked eye.

여기에서 본 고안은 네온램프(NL1)(NL2)와 릴레이(Ry1)의 사이에는 한류 저항(R1)(R2)를 연결시켰기 때문에 릴레이(Ry2)의 "a"접점(Ry2a1)(Ry2a2)와 릴레이(Ry1) 접점(Ry1a1)(Ry1a2) 이상으로 인한 혼촉을 방지할 수 있다.Since the present invention connects the current-limiting resistor R 1 (R 2 ) between the neon lamp NL 1 (NL 2 ) and the relay Ry 1 , the “a” contact (Ry) of the relay Ry 2 . 2 A 1 ) (Ry 2 a 2 ) and the relay (Ry 1 ) contact (Ry 1 a 1 ) (Ry 1 a 2 ) can be prevented from mixing.

또한 릴레이(Ry1)(Ry1)는 푸쉬보턴 스위치(BSw1)(BSW2)에 의하여 동시 동작됨을 방지하기 위하여 램프테스트 푸쉬버튼 스위치(BSW1)를 "온"시키면 그의 "b"접점이 개방되어짐과 동시에 단선검출 푸쉬버튼 스위치(BSW2)는 "온" 되어지고 그의 "b"접점(BSW2b)이 개방되어져 릴레이(Ry2)는 록(LOCK)되어서 동작을 하지 않게 되고 반대로 단선검출 푸쉬버튼 스위치(BSW2)를 누르면 개방되어짐과 동시에 그의 "b"접점(BSW2)과 램프테스트 푸쉬버튼 스위치(BSW1)의 "b"접점(BSW1)이 단락되어지는 인터록(Inter-LocK)회로로 구성되어 있기 때문에 안전하다.In addition, the relay Ry 1 (Ry 1 ) "turns on" the lamp test pushbutton switch BSW 1 to prevent simultaneous operation by the pushbutton switches BSw 1 and BSW 2 . At the same time, the disconnection detection pushbutton switch (BSW 2 ) is "on" and its "b" contact (BSW 2 b) is opened so that the relay (Ry 2 ) is locked and inoperable. pressing the push-button detection switch (BSW 2) open at the same time his doeeojim and "b" contacts (BSW 2) and a lamp test pushbutton switch "b" contact point (BSW 1) which is a short circuit of the interlock (BSW 1) (Inter- It is safe because it consists of LocK) circuit.

그리고 단위 검출 회로(SW1)는 솔레노이드 밸브(Ry1)의 수와 비례하여 연결된다.The unit detection circuit SW 1 is connected in proportion to the number of solenoid valves Ry 1 .

본 고안은 토글 스위치(SW1) 내지는 릴레이(Ry1)(Ry2)를 대신하여 세렉터 스위치를 사용할 수 있으며 또한 네온램프(NL1)(NL2)를 대신하여 D.C 정류회로를 이용한 발광다이오드를 사용할 수도 있다.The present invention can use a selector switch in place of a toggle switch (SW 1 ) or a relay (Ry 1 ) (Ry 2 ) and a light emitting diode using a DC rectifier circuit instead of a neon lamp (NL 1 ) (NL 2 ). You can also use

이상에서와 같이 본 고안은 종래처럼 별도의 계측기를 사용하여 솔레노이드 밸브 코일의 단선 유무를 확인하여야 하는 번거러움이 없으며 또한 간단한 방법으로 첵크할 수 있어 생산의 능률화에 기여할 수 있는 작용 효과가 있다.As described above, the present invention does not have to check the disconnection of the solenoid valve coil using a separate measuring device as in the prior art, and can be checked by a simple method, which has an effect of contributing to the streamlining of production.
