In addition, it is possible to accurately measure, and to determine the forward and reverse rotation directions of the blower motor by START LAMP and NG LAMP by the final relay drive.
상기와 같은 목적을 달성하기 위한 본 발명을 첨부한 실시예의 도면에 따라 상세히 설명하면 다음과 같다.When described in detail according to the accompanying drawings of the present invention for achieving the above object is as follows.
제 1 도에 도시한 바와같이 통상의 블로워 모우터(B/M)와 지그(Jig) 및 RPM측정표시부(3), 모우터의 정, 역 방향표시부(4)로 이루어진 측정장치에 있어서, 상기 지그(Jig)에 블로워 모우터(B/M)의 정, 역 회전방향을 감지하는 2개의 근접스위치인 감지센서(Sen1), (Sen2)와 감지센서(Sen1), (Sen2)에 의해 블로워 모우터(B/M)의 회전속도에 따라 RPM을 정확하게 측정해주기 위한 엔코더회로(1)와 블로워 모우터(B/M)의 정, 역 회전방향을 START LAMP 와 NG LAMP를 통해 판정해주기 위한 릴레이구동부(2)로 구성되어 있다.As shown in FIG. 1, in the measuring device comprising a conventional blower motor (B / M), a jig (Jig), an RPM measurement display unit (3), a positive and reverse direction display unit (4) of the motor, Two proximity switches detecting the forward and reverse rotation directions of the blower motor (B / M) on the jig (Sen 1 ), (Sen 2 ), and (Sen 1 ), (Sen 2 ) By using START LAMP and NG LAMP, the direction of forward and reverse rotation of encoder circuit (1) and blower motor (B / M) to accurately measure RPM according to the rotation speed of blower motor (B / M) is determined by It consists of a relay driving part (2).
상기 엔코더회로(1)는 2개의 감지센서(24a)(24b)의 출력단에서 발생하는 2개의 구형파의 위상차를 검출하여 블로워 모우터(10) 출력측(11)의 회전속도 및 회전방향을 검출하는 공지의 회로이며, 릴레이구동부(2)는 2개의 트랜지스터(TR1)(TR2) 및 릴레이(RY) 등으로 구성되어 있다.The encoder circuit 1 detects the phase difference of two square waves generated at the output terminals of the two sensing sensors 24a and 24b to detect the rotational speed and the rotational direction of the output side 11 of the blower motor 10. The relay driver 2 is composed of two transistors TR 1 (TR 2 ), a relay RY, and the like.
상기와 같이 구성된 본 발명의 작용효과를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.If described in detail according to the accompanying effects of the present invention configured as described above are as follows.
먼저 블로워 모우터(B/M)를 지그(Jig)내에 고정되게 삽입시킨 후 블로워 모우터(B/M)에 연결된 플러그(도시생략)를 잭(도시생략)에 접속시키면 블로워 모우터(B/M)는 DC 12V에 의해 회전하게 된다.First, blower motor B / M is fixedly inserted into jig, and when the plug (not shown) connected to blower motor B / M is connected to the jack (not shown), blower motor B / M M) is rotated by DC 12V.
이때 블로워 모우터(B/M)의 회전속도를 2개의 근접스위치인 감지센서(Sen1), (Sen2)에서 감지하게 되는데 2개의 감지센서(24a)(24b)는 물체가 접촉한 것을 무접촉으로 검출하는 근접스위치(proximity switch)로서 리드스위치와 영구 자석을 짜맞춘 자기형 근접스위치 중에서 리드스위치가 봉입되어 있는 콘택트부와 영구자석이 내장되어 있는 마그넷부로 분리된 '분리형'이므로 콘택트부를 고정시켜 두고 마그넷부를 부착한 검출체를 근접시켜 마그넷센터와 스외치센터가 일치하면 자기회로를 형성시켜 리드스위치의 접점이 닫히며, 반대로 마그넷부가 떨어지면 자기 회로가 끊기고 리드스위치의 접점이 열리게 되므로 이에 의하여 2개의 감지센서(24a)(24b)의 출력단에는 위상차를 갖는 구형파가 발생된다.At this time, the rotation speed of the blower motor (B / M) is detected by two proximity switches (Sen1) and (Sen2). The two detection sensors 24a and 24b contactlessly contact an object. It is a proximity switch that detects the contact switch, which is separated from the magnetic type proximity switch where the reed switch and the permanent magnet are combined, the contact part in which the reed switch is sealed and the magnet part in which the permanent magnet is built, so the contact part is fixed. When the magnet center is close to the detector with magnet part, the magnetic center forms a magnetic circuit, and the contact of the reed switch is closed. Square waves having a phase difference are generated at the output terminals of the detection sensors 24a and 24b.
따라서 엔코더회로(30a)는 상기 구형파의 위상차를 검출하여 블로워 모우터(10) 출력측(11)의 회전속도 및 회전방향을 측정하여 RPM 측정표시부(50)를 통해 RPM을 표시하고 릴레이구동부(40)를 거쳐 정, 역 회전방향 표시부(60)에 회전방향을 표시하는 공지의 회로이며, 릴레이구동부(40) 역시 2개의 트랜지스터(TR1)(TR2)와 자기유지릴레이(RY)를 이용하여 구성되는 공지의 회로이다.Therefore, the encoder circuit 30a detects the phase difference of the square wave, measures the rotational speed and the rotational direction of the blower motor 10 output side 11, displays the RPM through the RPM measurement display unit 50, and relay drive unit 40. It is a well-known circuit which displays the rotation direction on the forward and reverse rotation direction display part 60 via the relay drive part 40, The relay drive part 40 is also well-known comprised using two transistors TR1 (TR2) and the magnetic holding relay RY. Is the circuit.
릴에이구동부(40)는 2개의 트랜지스터(TR1)(TR2)와 자기유지릴레이(RY)로 구성되는 공지의 회로이며, 자기유지릴레이란 러칭릴레이 또는 카프릴레이라고도 하며, 상측 동작코일(50), 하측에 복귀코일(44)이 있으며 아마추어 선단의 캠판(43)으로 기계유지를 하는데, 일단 여자되어 동작하면 전자코일의 전류를 끊더라도 그 동작을 유지하여 이를 복귀시키려면 재차 외부에서 전류를 가하도록 되어있다.The relay A driving unit 40 is a well-known circuit composed of two transistors TR 1 (TR 2 ) and a magnetic sustain relay RY. The magnetic sustain relay is also referred to as a latching relay or a capillary, and the upper operating coil 50 ), There is a return coil 44 at the lower side, and the machine is held by the cam plate 43 of the armature tip. Once excited and operated, even if the current of the electronic coil is cut off, the current is maintained again from the outside to maintain the operation. It is supposed to be.
자기유지릴레이는 제 2 도에 도시된 바와같이 동작코일(50)에 전류가 흐르면 동작아마추어(41)가 흡인되어 캠판(42)이 캠판(43)의 단부분에 걸려 동작코일(50)의 여자를 풀더라도 그대로의 상태를 유지하며, 복귀코일(44)에 전류가 흐르면 복귀 아마추어(45)를 흡입캠판(43)이 캠판(42)에서 떨어져 동작아마추어(41)가 원래 위치로 복귀하는 동작을 하게 되며, 상기 2개의 트랜지스터(TR1)(TR2)는 각각 엔코더회로(30)가 정, 역방향을 판별하여 2개 중에서 하나의 트랜지스터의 베이스에 '하이'신호를 입력시키면 트랜지스터(TR1)는 동작코일(50)에 전류를 흘려 가동접점(S1)을 A로 이동시키므로 정, 역방향표시부(60)의 스타트램프(60a)를 점등시키고 트랜지스터(TR2)는 복귀코일(44)에 전류를 흘려 가동접점 B로 복귀시키므로 NG LAMP(60b)를 점등시키게 되므로 다량의 불량 제품을 부저를 통해 판정할 수 있는 것이다.As shown in FIG. 2, when the current flows through the operating coil 50, the self-holding relay is attracted to the operating amateur 41, and the cam plate 42 is caught by the end of the cam plate 43 to excite the operating coil 50. Is maintained even if the air is released, and when the current flows in the return coil 44, the return armature 45 is removed from the cam plate 42, and the armature 41 returns to its original position. In the two transistors TR 1 and TR 2 , the encoder circuit 30 determines whether the encoder circuit 30 is positive or reverse, and inputs a high signal to the base of one of the two transistors TR 1 . Since the current flows through the operating coil 50 to move the movable contact S1 to A, the start lamp 60a of the forward and reverse display unit 60 is turned on and the transistor TR 2 supplies a current to the return coil 44. As it flows back to the movable contact point B, the NG LAMP (60b) is turned on. The product can be judged by the buzzer.
이상에서와 같이 동작되는 본 발명은 간단한 구성에 의하여 작업자가 모우터의 회전부위에 손을 대지 않고서도 2개의 감지센서에 의한 블로워 모우터의 정, 역 회전방향을 감지할 수 있게 하였으며, 또 블로워 모우터의 회전속도에 따라 RPM을 정확하게 측정할 수가 있고, 아울러 블로워 모우터의 정, 역 회전방향을 START LAMP와 NG LAMP를 통해서 판정해주므로써 생산성을 향상시킬 수 있는 효과가 있는 것이다.The present invention operated as described above allows the operator to detect the forward and reverse rotation directions of the blower motor by the two detection sensors without touching the rotating part of the motor by a simple configuration, and the blower RPM can be accurately measured according to the rotational speed of the motor, and the direction of forward and reverse rotation of the blower motor can be determined by START LAMP and NG LAMP, thereby improving productivity.
