이하, 첨부된 도면에 의거하여 본 발명을 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

제2도는 상기 담배적재장치(1)의 구동회로도를 나타낸 것으로, 본 발명에 따른 제어방법을 내부 메모리에 저장하여 각종 제어를 수행하는 원칩 마이크로 컴퓨터(20)(이하 마이콤이라 함)의 포트(Pa1∼Pan)에는 저항(Ra1∼Ran), 트랜지스터(Qa1∼Qan), 다이오드(Da1∼Dan), 콘덴서(Ca1∼Can), 담배투출용 모터(M1∼Mn), 써미스터(PTC) 및 콘덴서(C0)로 이루어진 투출용 모터구동부(30)가 접속되어 상기 마이콤(20)의 일정출력으로 각 모터(M1∼Mn)를 구동하게 되는데, 일례로 모터(M1)를 구동하기 위하여 마이콤(20)이 포트(Pa1)로 로우신호를 출력하면 트랜지스터(Qa1)가 턴온되어 써미스터(PTC)의 일단에 걸려있던 전원(VCC)가 모터(M1)에 인가되어 모터(M1)는 구동회전 한다.2 shows a driving circuit diagram of the cigarette loading device 1, which stores a control method according to the present invention in an internal memory and performs various controls to control a port P of a one-chip microcomputer 20 (hereinafter referred to as a microcomputer). ~P an a1), the resistor (R a1 ~R an), the transistor (Q a1 ~Q an), a diode (D ~D an a1), a capacitor (C a1 ~C an), cigarette-to-chulyong motor (M 1 ~ A discharging motor driver 30 composed of M n ), a thermistor (PTC) and a condenser (C 0 ) is connected to drive each motor (M 1 to M n ) with a constant output of the microcomputer 20. When the microcomputer 20 outputs a low signal to the port P a1 in order to drive the low motor M 1 , the transistor Q a1 is turned on so that the power supply V CC that is applied to one end of the thermistor PTC is the motor. It is applied to (M 1) the motor (M 1) is rotationally driven.

또한, 마이콤(20)의 다른 포트(Pb1∼Pbn)에는 저항(Rb1∼Rbn), 검출스위치(SW1∼SWn)로 구성된 모터구동검지부(40)가 접속되게 되는데 상기 검출스위치(SW1∼SWn)는 각각 제1도에 도시된 바와 같이, 상기 투출용 모터구동부(30)의 각 모터(M1∼Mn)들 중 해당코터에 각기 대응하여 설치되어 마이콤(20)의 제어에 의해 해당모터가 구동되어 이동부(9)가 좌우로 이동될 경우 연결구(7)에 마련된 감지대(8)에 의해 온·오프되도록 설치된다. 즉, 모터(M1∼Mn)의 구동에 따라 그에 대응되는 해당 검출스위치(SW1∼SWn)가 온·오프하게 되어 있다.In addition, the motor drive detection unit 40 composed of the resistors R b1 to R bn and the detection switches SW1 to SW n is connected to the other ports P b1 to P bn of the microcomputer 20. SW 1 to SW n are respectively installed to correspond to the corresponding coater among the motors M 1 to M n of the discharging motor driving unit 30 as shown in FIG. When the motor is driven by the control and the moving unit 9 is moved left and right, it is installed to be turned on and off by the sensing table 8 provided in the connector 7. In other words, the motor (M 1 ~M n) the detection switches (SW 1 ~SW n) which in accordance with the driving of the corresponding to on-off.

따라서, 마이콤(20)은 상기 검출스위치(SW1∼SWn)의 온·오프에 따른 입력포트(Pb1∼Pbn)로의 로우 및 하이신호 입력에 따라 이를 인식하여 모터(M1∼Mn) 구동정지명령 또는 후술하는 투출불량현상을 검출하게 되고, 투출불량부위에 따른 일정코드표시 및 매진처리표시를 통상의 표시부(50)로 출력하여 준다.Therefore, the microcomputer 20 recognizes the low and high signal inputs to the input ports P b1 to P bn according to the on / off of the detection switches SW 1 to SW n to recognize the motors M 1 to M n. The drive stop command or a discharge failure phenomenon to be described later is detected, and a constant code display and a sold out process display corresponding to the discharge failure portion are output to the normal display unit 50.

이하 제3도에 제어흐름도를 통해 본 발명의 구체적인 제어방법을 설명한다.Hereinafter, a detailed control method of the present invention will be described with reference to FIG. 3.

본 발명을 실현하기 위한 제2도와 같은 회로에 전원(VCC)이 인가되고 미도시된 키이입력수단을 통해 특정칼럼의 상품이 선택되어져 그 신호가 입력되면 담배자동판매기의 주제어루틴에서 본 발명에 따른 판매 및 에러체크루틴으로 프로그램은 전환된다.When a power source V CC is applied to a circuit as shown in FIG. 2 for realizing the present invention and a product of a specific column is selected through a key input means (not shown), and a signal thereof is input, the main routine of the cigarette vending machine is applied to the present invention. The program is switched to the sales and error checkouts that follow.

우선, 이러한 판매개시시 마이콤(20)은 선택된 칼럼의 검출스위치(SW)가 온(ON)인가를 판단하여 초기상태인 오프(OFF)가 아닐 경우 해당칼럼 검출스위치(SW)가 단락(SHORT)(클로우즈형 스위치인 경우에는 단선(OPEN))된 불량상태로 판단함으로써 해당칼럼을 매진처리하기 위해 표시부(50)로 매진램프점등신호를 출력하고, 동시에 해당칼럼 검출스위치(SW) 불량에 따른 특정코드신호를 숫자표시용 LED로 출력한다.First of all, at the start of the sale, the microcomputer 20 determines whether the detection switch SW of the selected column is ON and if the initial detection state is not OFF, the corresponding column detection switch SW is shorted. (In case of close type switch, it is disconnected), it outputs the sold out lamp lighting signal to the display unit 50 to process the column sold out by judging it as the defective state, and at the same time, it is specified by the corresponding column detection switch SW. Output code signal to LED for number display.

상기 판단과정(S1)에서 검출스위치(SW)가 정상일 경우 선택된 칼럼의 모터(M)를 구동시키기 위하여 모터구동신호를 출력하여 담배투출운전이 시작되면, 모터구동 후 1.2초가 경과되었는가를 판단하게 되는데 여기서 1.2초의 시간은 모터(M)가 구동하여 이동부(9)가 움직이고 감지대(8)가 이동하여 검출스위치(SW)를 온시킬 수 있는 최대한의 시간으로 보통, 모터구동 후 0.9초면 검출스위치(SW)는 온되게 된다.When the detection switch SW is normal in the determination process S 1 , when the cigarette discharge operation is started by outputting a motor driving signal to drive the motor M of the selected column, it is determined whether 1.2 seconds have elapsed after the motor driving. The time of 1.2 seconds is the maximum time that the motor (M) is driven to move the moving unit (9) and the sensing table (8) to turn on the detection switch (SW), usually 0.9 seconds after the motor is detected The switch SW is turned on.

따라서 이러한 1.2초내에 검출스위치(SW)가 온되지 아니한다면 그것은 검출스위치(SW) 자체의 고장 또는 모터의 고장으로 감지대(8)가 이동되지 못한 것으로 판단하여 모터정지신호를 출력함과 동시에 해당칼럼 매진신호와 상기 검출스위치(SW) 및 모터(M) 불량에 따른 특정코드표시를 표시부(50)로 출력한다.Therefore, if the detection switch SW is not turned on within such 1.2 seconds, it is determined that the detection stand 8 has not moved due to a failure of the detection switch SW itself or a motor failure, and then outputs a motor stop signal. A column sold signal and a specific code display according to the detection switch SW and the motor M are output to the display unit 50.

또한, 상기 판단과정(S2)에서 검출스위치(SW)가 정상적으로 눌리어 온 신호가 검출되면, 차후 검출스위치(SW)가 오프되는 시점에서 모터(M)를 정지하여 담배투출을 완료하고 정상판매 상태로 진행하나 모터구동 후 2.4초가 경과되도록 검출스위치(SW)가 온상태를 유지하게 되면 담배(3)의 적재불량(어긋남)으로 기인된 투출불량현상으로 모터(M)가 구동함에도 밀대(4)가 담배(3)를 밖으로 투출시키지 못하여 검출스위치(SW)가 오프되지 못하는 것으로 판단하여 해당칼럼의 매진표시 및 상기 원인에 따른 불량을 특정코드표시로 하여 표시부(50)로 출력하고, 투입된 금액을 반환하여 준다.In addition, if the detection switch SW is normally pressed in the determination process (S 2 ), when the on-signal is detected, the motor (M) is stopped at the time when the detection switch (SW) is turned off later to complete the cigarette discharge and sell normally. If the detection switch SW is kept on for 2.4 seconds after the motor is driven, the pusher can be operated even when the motor M is driven due to a discharge failure caused by a loading failure (deviation) of the cigarette 3. ) Is determined that the detection switch (SW) cannot be turned off because the cigarette (3) cannot be discharged out, and the sold out of the corresponding column and the defect according to the cause are output to the display unit (50) by displaying a specific code. Return the amount.

또한, 상기 2.4초의 시간은 검출스위치(SW)가 디시 오프로 초기화되는 최대한의 시간으로 보통, 오프→온→오프되는 총시간은 1.8초 정도이다.In addition, the time of 2.4 seconds is the maximum time that the detection switch (SW) is initialized to the dish off, usually, the total time off → on → off is about 1.8 seconds.

이상에서와 같이 본 발명은 담배자동판매기의 담배투출불량시 고장난 부위를 정확히 외부로 알려줌으로써 신속하게 그 부위를 판단할 수 있어 수리시 용이한 이점이 있다.As described above, the present invention can be quickly determined by informing the outside of a broken part of a cigarette dispensing machine of a cigarette vending machine, so that the part can be quickly determined for repair.
