본 발명은 자동판매기나 동전교환기등에서 사용되는 거스름돈 불출장치에 관한 것으로서 특히, 거스름돈 불출판에 형성된 주화수납구의 밑면에 걸림 돌출턱을 설치하고, 장치내의 ROM내에는 동시 불출 제어프로그램을 기억시켜 거스름돈의 불출작동이 순간적이면서도 정확하게 될수 있도록한 거스름돈 불출장치에 관한 것이다.The present invention relates to a change dispenser used in a vending machine or a coin exchanger. In particular, a jaw projection is provided at the bottom of a coin storage formed in the change dispenser, and a simultaneous dispensing control program is stored in a ROM in the device to change the change. It is about the change dispensing device which makes the dispensing operation instantaneous and accurate.

종래에는 종류별 주화통 밑에 솔레노이드나 모터로 가동되는 가동편을 설치하고, 가동편에는 해당주화의 직경과 동일하거나 약간큰 구멍을 형성하여 가동편의 이동에 의하여 거스름돈을 불출하도록 하고 있으나, 다수개의 구멍을 형성한 가동편이나 하나의 구멍을 형성한 가동편이나 거스름돈의 주화에 개수에 해당되는 횟수만큼을 가동편을 구동하도록 되어있어 불출속도가 늦고, 이에따른 기계적구조의 피로와 마모가 크게되어 불출장치 전체의 사용수명이 짧아지는 단점이 있을뿐 아니라, 가동편밑에 동전의 불출을 제어하기위한 솔레노이드나 솔레노이드편이 부착되어 가동편의 이동시에 가동편과 함께 이동되도록 하고있어 가동편의 구동용 솔레노이드나 모터의 부하용량이 크게되어 자동판매기의 외형 칫수가 점점작고 슬림(Slim)화되는 추세에 비추어볼때 그 설치가 어렵게 되는 단점이 있다.Conventionally, a movable piece that is operated by a solenoid or a motor is installed under a coin box of each type, and the movable piece is formed to have a hole equal to or slightly larger than the diameter of the corresponding coin so as to discharge change by moving the movable piece. The moving piece is driven as many times as the number of moving pieces or moving pieces formed with one hole or change coins, so that the discharging speed is slow and the fatigue and abrasion of the mechanical structure is increased. In addition to the shortening of the service life of the whole, a solenoid or solenoid piece for controlling coin dispensing under the movable piece is attached to move together with the movable piece when the movable piece moves. As the capacity increases, the external dimension of the vending machine becomes smaller and slim. I see that the light has the disadvantage that the installation is difficult.

본 발명은 이러한 종래의 단점을 해결하기 위하여 불출장치에 내장된 제어부의 ROM내에는 동시 불출 제어프로그램을 기억시켜 거스름돈 불출판이 되는 가동편의 가동횟수를 크게줄여, 불출장치의 기계적구도의 피로와 마모의 발생을 극력억제 하므로서 불출장치의 전체사용수명을 연장시키며, 또한 가동편만이 가동되도록하여 가동편 구동용 모터의 용량을 작게할수 있어 슬림화추세에 발맞출수 있는 거스름돈 불출장치를 제공하는것을 목적으로하며, 이하 첨부된 도면을 참조하면서 본 발명장치를 더욱 상세히 설명하면 다음과 같다.In order to solve the above disadvantages, the present invention stores a simultaneous dispensing control program in the ROM of the control unit built in the dispensing apparatus, thereby greatly reducing the number of times of operation of the movable piece that becomes the change dispensing plate. Its purpose is to provide a change dispensing device that can keep up with the trend of slimming by prolonging the entire service life of the dispensing device by restraining the occurrence of power, and by reducing the capacity of the moving piece driving motor by allowing only the movable pieces to operate. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

If there is a 10 won coin, check whether the balance is more than 10 won (S ₁₄ ), and if the balance is more than 10 won, subtract 10 won from the balance (S ₁₅ ), 1 After increasing the coefficient of the zero-counter by one (S ₁₆ ), it is checked whether there is a ten-won auxiliary yuan 10 won coin (S ₁₇ ), and if the 10-won coin is not in the auxiliary box, the process returns to step (14), and the 10-won coin is subsidized If it is in the container, check whether the balance is more than 10 won (S ₁₈ ), if the balance is more than 10 won, subtract 10 won from the balance (S ₁₉ ), and then increase the coefficient of the auxiliary 10-counter counter (S ₁₄ ).

우선, 마이크로 컴퓨터내에는 판매프로그램이 기억되어 있는데 이러한 판매 프로그램은 공지의 사항이므로 여기에서는 별도로 상세한 설명은 명세서의 간결화를 위해 생략한다.First, a sales program is stored in the microcomputer. Since the sales program is a well-known matter, a detailed description is omitted here for the sake of brevity of the specification.

다만, 판매프로그램내에는 각각의 액면에 해당되는 주화가 주화튜브내에 14개 이하인 경우에는 주화가 없는 것으로 판단하고 판매중지 즉 투입된 주화는 직접 반환구로 되돌려 보낸다.However, if there are 14 coins or less in each coin tube in the sales program, it is determined that there are no coins, and the coins which have been discontinued, that is, are returned to the return port directly.

평상시에는 제3도에서와 같이 가동판이 배출위치에 있으나, 구멍(A-E)에 끼워진 주화는 돌기(1)와 가동돌기(5)에 의하여 지지되고 있으므로 구멍(A-E)상의 주화는 배출되지 못하는 상태가 된다.Normally, as in FIG. 3, the movable plate is in the discharge position, but since the coin inserted in the hole AE is supported by the protrusion 1 and the movable protrusion 5, the coin on the hole AE cannot be discharged. do.

이 상태는 제2a도에서와 같다. 이러한 상태에서 주화 배출용 솔레노이드(6)가 작동되어 제2b도에서와 같이 가동돌기(5)를 화살표 (가)방향으로 이동시키게 되므로 가동돌기(5)는 더 이상 주화(M)를 지지하지 못하므로 주화(M)는 화살표 (나)와 같이 호형 궤적을 그리며 배출된다. 여기에서 솔레노이드(6)의 작동시간은 주화(M)가 충분히 떨어질수 있도록 대략 250μ초 정도로 한다.This state is the same as in FIG. 2A. In this state, the coin discharging solenoid 6 is operated to move the movable protrusion 5 in the direction of the arrow (a) as shown in FIG. 2b, so that the movable protrusion 5 can no longer support the coin M. Therefore, the coin (M) is discharged by drawing an arc trajectory as shown by the arrow (b). Here, the operation time of the solenoid 6 is approximately 250 μs so that the coin M can fall sufficiently.

이후 모터(7)가 반회전하면 제2d도와같이 가동판(2)이 주화튜브(L) 밑으로 이동되어 가동판(2)의 구멍(A-E)에는 주화튜브(L)내의 주화(M)가 구멍(A-E)내로 삽입되는데 가동판(2)의 두께 (2A)는 주화(M)의 두께보다 약간 얇게되어 있어 가동판(2)의 구멍(A-E)내에는 하나의 주화만 위치된다.Then, when the motor 7 rotates halfway, the movable plate 2 is moved under the coin tube L as shown in FIG. 2D, and the coin M in the coin tube L is inserted into the hole AE of the movable plate 2. Inserted into the hole AE, the thickness 2A of the movable plate 2 is slightly thinner than the thickness of the coin M, so that only one coin is located in the hole AE of the movable plate 2.

물론 이때에도 구멍(A-E)밑부분에는 가동돌기(5)가 위치되어 주화(M)가 밑으로 빠지는 것을 방지한다.Of course, even at this time, the movable projection 5 is positioned at the bottom of the hole A-E to prevent the coin M from falling out.

제2c도에서는 가동돌기(5)가 후진된 상태에서 가동판(2)의 구동모터(7)가 반회전되어 있는 경우가 도시되어 있는데 이때에는 가동돌기(5)가 완전히 후진되어(제2c도에서 좌측방향) 연속주화를 배출할수 있는 경우가 도시되어 있다. 이러한 경우는 본 발명의 범위내에 속하는 다른 실시적인 예시도이다.2c shows a case in which the driving motor 7 of the movable plate 2 is half rotated while the movable protrusion 5 is reversed. In this case, the movable protrusion 5 is completely reversed (FIG. In the left direction) is shown a case where the continuous coin can be ejected. This case is another exemplary illustration within the scope of the present invention.

또한 제4도를 참조하면 본 발명 장치에 의하면 가동판(2)의 1회 작동에는 가동판(2)에 형성된 주화구멍(A-E)마다 주화가 전부 차있는 상태이므로 예를들어 170원을 거스르는 경우나 670원을 거스르는 경우에는 가동판(2)의 1회작동과 각해당 액면 솔레노이드가 작동되는 것으로 완결될수 있음을 알수 있다.Referring to FIG. 4, according to the apparatus of the present invention, the coin is filled with every coin hole AE formed in the movable plate 2 in one operation of the movable plate 2, for example, when it goes against 170 won. (B) if it goes against 670 won, it can be concluded that the movable plate (2) is operated once and the corresponding liquid solenoid is activated.

즉, 거스름돈이 170원인 경우에는 100원동전 1개, 50원동전 1개, 10원동전 2개가 되고, 670원인 경우에는 500원 동전 1개 100원동전 1개, 50원동전 1개, 10원 동전 2개의 동전이 불출되면 되는 것이므로 가동판(2)의 1회 작동과 각 솔레노이드(6)가 1회씩 작동으로 불출작동이 완료된다. 여기에서 구멍(A-E)은 각각 500원주화, 100원주화, 50원주화, 10원주화×2용이다.That is, if the change is 170 won, one 100 won, one 50 won, and two 10 won coins, and for 670 won, one 500 won coin, one 100 won coin, one 50 won coin, and 10 won Coins Since two coins are to be dispensed, the dispensing operation is completed by one operation of the movable plate 2 and one operation of each solenoid 6 once. The holes A-E are used for 500, 100, 50, and 10 × 2, respectively.

따라서 제2a-d도를 참조한 설명에서 알수 있는 바와같이 본 발명 장치에서는 가동판(2)만이 모터(7)의 구동력으로 이동되므로 모터(7)의 용량이 작아도 되는 것이며, 제4도를 참조한 설명에서와 같이 가동판(2)의 작동횟수를 대폭 감소시킬수 있어 장치의 수명을 크게 연장할수 있고, 더욱이 슬림화에 적합한 것이다.Therefore, as can be seen from the description with reference to Figs. 2a-d, in the present invention, only the movable plate 2 is moved by the driving force of the motor 7, so that the capacity of the motor 7 may be small. As can be greatly reduced the number of operations of the movable plate (2) can greatly extend the life of the device, it is more suitable for slimming.

If the coefficient of the 50 won counter is '0', it is checked whether the coefficient of the 10 won counter is '0' (S _24). ), 10 won total Checking the applied coefficient is "0", 10 won the zero coefficient of the secondary counters of the group, and (S _25), if the zero coefficient of 10 won the secondary counter kkeutnaemyeo all of the steps (S _26), step (S ₂₂ -S ₂₅ ) If the coefficient is not '0', the driving motor 7 is operated once (S ₂₇ ) 500 won After checking whether the coefficient of the counter is '0' (S ₂₈ ), 500 won in which the modulus of the counter is not '0' 1 reduces the coefficient of US $ 0.50, the counter, and then (S _29), sikimyeo 500 won operation once the coin solenoid (S _30), step (S ₂₈₎ the coefficient of US $ 0.50 counters in After one-time operation of '0' or 500 won coin solenoid, it is checked whether the count of 100 won counter is '0' (S ₃₁ ), and if the count of 100 won counter is not '0', After subtracting 1 '(S ₃₂ ), the 100-won coin solenoid is operated once (S ₃₃ ), and in step (S ₃₁ ), the coefficient of the 100-won counter is'0' or the 100-won coin solenoid is operated once. Then 50 The modulus of the counter check for applying "0" and (S _34), or the coefficients are zero and 50 won counter was reduced to '1' the count of 50 won counter (S _35), 50 won the coin solenoid 1 Cycles operating sikimyeo (S _36), or a factor of 50 won counter in step 34, "0" after it is running once the 50 won coin solenoid checks the application of zero coefficients of the 10 won counter and (S ₃₇ ), If the coefficient of the 10-member counter is not '0', subtract 1 from the coefficient of the 10-member counter (S ₃₈ ), then operate the 10-element coin solenoid once (S ₃₉ ), and the coefficient is increased in step 37. If it is '0' or once the 10-element coin solenoid is operated, it is checked whether the coefficient of the secondary 10-counter counter is '0' (S ₄₀ ). after subtracting 1 in the counting of the counter (S _41), the auxiliary operation once the solenoid 10 won and (S _42), the coefficients in the step (S ₄₀₎ '0' or the secondary solenoid 10 won once the The change dispensing apparatus by storing the program goes back to the step 21 after the same time.
