도면의 설명중 미설명 부호 Vcc는 전원이다.In the description of the drawings, reference numeral Vcc denotes a power supply.

이와같이 구성된 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above in detail.

타이머(20)에 기어(90)의 정방향 및 역방향의 회전시간을 세팅(Seting) 시카고 전원(Vcc)을 인가하면 정전압 집적회로(110)(110')에서 일정 전압으로 되어 브리지정류기(B.D)와 트랜스(TS)를 통해 직류전류를 출력시켜 모터(80)를 구동시키면 기어(90)는 정방향으로 회전하며 이때 타이머(20)에 연결된 펄스발생기(130)가 작동하여 구형파 펄스를 생성하여 7번핀을 통해 타이머(20)에 인가하면 기어(90) 일측에 형성된 센서(30')는 스타트신호를 리미트스위치(S3) 단자(C)(O)를 통해 카운터(100)와 비씨디회로(40')의 9번핀에 연결시켜 카운터(100)에서 기어(90)의 회전방향 및 회전수를 기억하여 가감시키고 상기 비씨디회로(40')에서 입력된 10진숫자를 2진수로 바꾸어 11번핀을 통해 래치회로(70)에 기어(90)의 회전상태를 저장한다.Setting the rotational time of the forward and reverse directions of the gear 90 to the timer 20. When the Chicago power supply Vcc is applied, the constant voltage is constant in the constant voltage integrated circuits 110 and 110 '. When the motor 80 is driven by outputting a DC current through the transformer TS, the gear 90 rotates in the forward direction. At this time, the pulse generator 130 connected to the timer 20 operates to generate a square wave pulse to generate pin 7 When applied to the timer 20, the sensor 30 ′ formed at one side of the gear 90 transmits a start signal to the counter 100 and the BC circuit 40 ′ through the limit switch S 3 terminal C and O. 9 is connected to pin 9 of the counter to store and decelerate the rotational direction and the number of rotations of the gear 90 in the counter 100, and converts the decimal number inputted from the BC circuit 40 'into a binary number through pin 11 The rotation state of the gear 90 is stored in the latch circuit 70.

따라서 기어(90)가 정방향으로 회전하여 센서(30)까지 도달하면 센서(30')는 기어(90)에서 이탈되고 따라서 센서(30)에 감지된 신호는 리미트스위치(S2)단자(C)(O)를 통해 비씨디회로(40") 1번핀에 인가되고 이때 펄스발생기(130)의 구형파 펄스는 타이머(20')를 통해 비씨디회로(40)의 2번핀에 로우(low) 신호로 입력되므로 비씨디회로(40)(40")에서 하이 신호(high signal)로 바뀌어 비씨디회로(40)(40") 3번핀을 통해 래치회로(70) 5번핀과 래치회로(70') 11번 핀을 통해 저장되고 저장된 센서(30) 신호를 래치회로(70) 1번핀과 래치회로(70')9,13번 핀을 통해 출력되어 앤드게이트(120')으 각 입력단에 인가함과 동시에 래치회로(70)(70')의 5번핀과 9번핀을 통해 출력되어 앤드게이트(120') 출력단에 하이(high)신호가 출력되어 판정회로(60)의 6번핀을 통해 입력되어 기어(90)의 상태에서 정상이면 판정회로(60)의 1번핀에 연결된 발광다이오드(D1)가 점등되어 정상상태임을 알리고 기어(90)가 불량 상태이면 2번핀에 연결된 인버터(IN2)(IN3)를 통해 직류를 교류로 역반환시켜 발광다이오드(D3)를 점등시켜 기어(90)가 불량상태임을 알린다.Therefore, when the gear 90 rotates in the forward direction to reach the sensor 30, the sensor 30 'is separated from the gear 90, and thus the signal sensed by the sensor 30 is the limit switch S 2 terminal C. (0) is applied to pin 1 of the BC circuit 40 ", and the square wave pulse of the pulse generator 130 is a low signal to pin 2 of the BC circuit 40 through the timer 20 '. Since it is inputted, it is changed to a high signal from the BC circuits 40 and 40 ", and the latch circuit 70 and the pin 5 and the latch circuit 70'11 The sensor 30 signal stored and stored through pin 1 is outputted through pin 1 and latch circuits 70 'and pins 9 and 13 of the latch circuit 70, and the AND gate 120' is applied to each input terminal. It is output through pins 5 and 9 of the latch circuits 70 and 70 ', and a high signal is output to the output terminal of the end gate 120' and is input through pin 6 of the determination circuit 60. In the state of) If the decision is a light emitting diode (D 1) connected to the first pin of the circuit 60 is steady flow of direct current through the inverter (IN 2) (IN 3) coupled to a steady state second pin inform gear 90 is equal bad condition that The light emitting diode D 3 is turned on by the reverse return to indicate that the gear 90 is in a bad state.

또한 기어(90)가 역방향으로 회전할 때 센서(30)신호는 리미트스위치(S2) 단자(O)를 통해 비씨디회로(40") 1번핀에 인가되어 3번핀을 통해 래치회로(70')에 저장한후 기어(90)가 회전하여 센서(30')에 도달하면 센서(30') 신호를 리미트스위치(D3)를 통해 카운터(100)에 인가하는 한편 비씨디회로(40')를 거쳐 래치회로(70)에 저장하여 상기 래치회로(70)(70')에 저장된 신호를 앤드게이트(120') 입력단에 인가함과 동시에 래치회로(70)(70')를 인에이블 시키면 앤드게이트(120') 출력단에 하이(high) 신호가 출력되어 판정회로(60)의 5번핀을 통해 입력되어 정상이면 1번핀에 연결된 발광다이오드(D1)가 점등되어 정상임을 알리고 불량이면 2번핀에 연결된 발광다이오드(D2)를 점등시켜 불량상태임을 표시하여 사용자가 쉽게 알 수 있게 한다.In addition, when the gear 90 rotates in the reverse direction, the sensor 30 signal is applied to pin 1 of the BC circuit 40 "through the limit switch S 2 terminal O, and the latch circuit 70 'through pin 3. After the gear 90 rotates to reach the sensor 30 ', the sensor 30' signal is applied to the counter 100 through the limit switch D 3 while the BC circuit 40 'is applied. After the signal is stored in the latch circuit 70 and the signals stored in the latch circuits 70 and 70 'are applied to the input terminal of the AND gate 120' and the latch circuits 70 and 70 'are enabled, the AND gate is enabled. A high signal is output to the (120 ') output terminal and is input through pin 5 of the determination circuit 60. If it is normal, the light emitting diode D 1 connected to pin 1 is lit to indicate that it is normal. The light emitting diode D 2 is turned on to indicate that it is in a bad state so that the user can easily see it.

이상에서 상술한 바와같이 기어는 각종 산업분야에서 빼놓을 수 없을 만큼 여러분야에서 사용되므로 기어회전수를 카운터를 통해 판정회로에 입력되게 하여 모터를 정지시켜 기어의 마모상태를 사전에 파악하여 보다 정밀한 제품을 양산해낼 수 있는 효과를 가지는 유용한 고안인 것이다.As described above, the gear is used in the field as much as it can not be missed in various industrial fields, so that the gear rotation speed is input to the determination circuit through the counter to stop the motor to grasp the wear state of the gear in advance, so that the more precise product It is a useful design having the effect of mass production.
