본 고안은 자동판매개에서 제품 미인출시 추가동작에 의해 제품이 다시 인출되지 않도록 방지하는 회로에 관한 것이다.The present invention relates to a circuit for preventing a product from being pulled out again by an additional operation when the product is not drawn out from the automatic vending machine.
종래의 자동판매기에서는 사용자가 여러개의 제품을 구입하기 위해 그에 해당하는 금액을 넣고서 연속해서 제품을 꺼내는 경우에 버튼을 누르고 제품을 꺼내지 않은 상태에서 다시 버튼을 누름으로써 제품이 겹쳐 망실되는 결점이 있었다.In a conventional vending machine, when a user inputs a corresponding amount to purchase a plurality of products and continuously takes out products, the user presses a button and then presses a button again without removing the product.
따라서 본 고안의 목적은 자동판매기의 사용자가 실수함을 방지하기 위해서, 제1도에 도시한 바와 같이 자동판매기의 제품 인출부에 발광다이오드(PD)와 수광트랜지스터(PT)를 장착시켜서 제품의 미인출을 감지하게하여 미인출시 다시 버튼을 눌러도 제품이 인출되지 않도록 하는 회로를 제공하는 데 있다.Therefore, the object of the present invention is to install the light emitting diode (PD) and the light receiving transistor (PT) in the product outlet of the vending machine, as shown in FIG. It is to provide a circuit that makes it possible to detect the outgoing so that the product is not drawn out even if the button is pressed again when not drawn out.
이하 제2도에 도시한 본 고안의 회로도에 의한 실시예를 상세히 설명한다.Hereinafter, an embodiment according to the circuit diagram of the present invention shown in FIG. 2 will be described in detail.
제2도에 있어, 저항(R1, R2)을 각각 거친 전원(Vcc)이 발광다이오드(PD)와 수광트랜지스터(PT)는 제품인출부에 연결하고, 이 발광다이오드(PD)에서의 빛을 수광하여 도통되는 수광트랜지스터(PT)의 콜렉터신호는 저항(R3)을 거쳐서 트랜지스터(Q1)를 도통시키도록 연결하며, 이 트랜지스터(Q1)의 콜렉터에는 저항(R4)을 거친 전원(Vcc)을 인가함과 동시에 릴레이(RLY)와 연결되어 있고, 이 릴레이(RLY)가 구동됨에 따라 연동으로 전환되는 스위치(SW1,SW2)는 제어되며 또한 램프(LP)가 구동된다.In FIG. 2 , the power supply Vcc, which has passed through the resistors R 1 and R 2 , respectively, connects the light emitting diode PD and the light receiving transistor PT to the product outlet, and the light from the light emitting diode PD collector signals of the light-receiving transistor (PT) to be conductive by receiving the and connected to via a resistor (R 3) continuity of the transistor (Q 1), the collector, the resistance (R 4) of the transistor (Q 1) via the power (Vcc) is connected to the relay (RLY) at the same time, the switch (SW 1 , SW 2 ) which is switched in conjunction with the relay (RLY) is controlled and the lamp (LP) is driven.
먼저, 자동판매기의 인출부에 제품유무를 감지하는 광다이오드(PD)의 수광트랜지스터(PT)를 설치하여서 릴레이(RLY)를 구동한다.First, the light receiving transistor PT of the photodiode PD for detecting the presence or absence of a product is installed in the outlet of the vending machine to drive the relay RLY.
만일 , 자동판매기내에 제품이 방치되어 있는 경우에는 발광다이오드(PD)의 빛을 수광트랜지스터(PT)가 수광하지 못하기 때문에 도통되지 않는다.If the product is left in the vending machine, the light is not turned on because the light receiving transistor PT cannot receive the light of the light emitting diode PD.
이때, 수광트랜지스터(PT)의 콜렉터신호는 하이전압으로서 트랜지스터(Q1)를 도통시키고, 이에따라 릴레이(RLY)는 전류가 흐르지 않아 오프된다.At this time, the collector signal of the light receiving transistor PT conducts the transistor Q 1 as a high voltage, whereby the relay RLY is turned off because no current flows.
따라서, 제품인출 구동장치로 공급되는 전원이 차단되기 때문에 사용자가 버튼 스위치를 누르더라도 제품이 인출되지 않는다.Therefore, since the power supplied to the product take-out driving device is cut off, the product is not withdrawn even if the user presses the button switch.
그리고, 릴레이(RLY)의 접점(a)은 온되어서 사용자가 버튼을 누를 때마다 램프(LP)가 점등되어 제품이 방치된 상태임을 알려준다.In addition, the contact point a of the relay RLY is turned on, and the lamp LP is turned on every time the user presses a button, thereby informing that the product is left unattended.
그러나, 자동판매기에 제품이 방치되어 있지 않은 상태에서는 수광트랜지스터(Q1)가 도통됨에 따라 릴레이 구동용 트랜지스터(Q1)는 도통되지 않는다.However, the relay driving transistor Q 1 does not conduct as the light receiving transistor Q 1 conducts in the state where the product is not left in the vending machine.
이때, 트랜지스터(RLY)의 콜렉터에 나타나는 하이전압은 릴레이(RLY)를 온 상태로 구동시켜 사용자가 버튼을 누를시에 제품인출구동장치가 동작되게하고, 또한 램프(LP)는 버튼조작에 관계없이 소등상태가 된다.At this time, the high voltage appearing on the collector of the transistor RLY drives the relay RLY to the on state so that the product take-out driving device is operated when the user presses the button, and the lamp LP is independent of the button operation. It goes out.
따라서, 본 고안에 의하면 사용자가 제품을 꺼내지 않은 상태에서 연속하여 버튼을 누르더라도 다음 제품이 인출되지 않게 되므로 제품이 겹쳐 망실됨을 방지한다.Therefore, according to the present invention, even if the user presses the button continuously without taking out the product, the next product is not drawn out, thereby preventing the product from being lost.
