본 고안은 회전식 선반대의 구동회로에 관한것으로서, 보다 상세하게는 영구자석과 전자석에서 발생하는 자계에 의해 선반을 회전하는 로타(Rotor)방식의 선반대 구동회로에 관한 것이다.The present invention relates to a drive circuit of a rotary shelf, and more particularly, to a rotor type drive circuit of a rotor type that rotates a shelf by a magnetic field generated from a permanent magnet and an electromagnet.

일반적으로 백화점이나 상점등의 쇼인도에 설치되어 구도 또는 안경 등을 회전시켜서 소비자 및 관람자들의 시선집중을 유도하여 구매의욕을 높이는데 사용도는 회전식 선반대는, 선반을 회전시키는 회전력을 발생하는 모터와 이모터의 회전속도를 일정하게 감속하여 상기 선반을 회전시키도록 되어있는데, 이 회전식 선반대 구동회로는 AC전원이나 밧테리에 충전된 DC전원을 사용하여 모터를 구동한다.In general, it is installed in a show in a department store or a store, and rotates a composition or glasses to induce the attention of consumers and viewers to increase purchase intention. A rotating shelf is a motor that generates rotational power to rotate a shelf and The rotation speed of this motor is decelerated at a constant speed to rotate the shelf. The rotary shelf drive circuit drives the motor using an AC power source or a DC power source charged in a battery.

이와같이 AC전원을 이용한 회전식 선반대의 구동회로 AC를 DC로 콘버팅시켜 모터에 공급하기 때문에 회로 구성이 복잡함과 동시에 제조단가가 상승하고, AC라인을 선반대 설치 장소까지 노출시켜야 하므로 외관미를 저하한다는 문제점이 있었다. 그리고 밧테리에 충전되어있는 DC전원을 이용한 회전식 선반대의 구동회는 모터 사프트에 선반이 기계적으로 접속되어 선반위에 놓인 물건을 회전시키기 때문에 선반위에 놓인 물건의 무게가 일정치 이상일때 모터에 과부하가 걸려 모터가 파괴되는 문제점과 모터 자체의 소비전력이 많아 밧테리를 자주 갈아주어야하는 불편한점이 있었다.As the drive circuit AC of the rotary shelf using AC power is converted to DC and supplied to the motor, the circuit configuration is complicated, the manufacturing cost increases, and the AC line must be exposed to the shelf installation location. There was a problem. In addition, the driving circuit of the rotary shelf using the DC power charged in the battery rotates the object placed on the shelf by mechanically connecting the shelf to the motor shaft, so when the weight of the object placed on the shelf exceeds a certain level, the motor is overloaded. There was a problem of breaking and a lot of power consumption of the motor itself had to change the battery frequently.

따라서 본 고안은 상기와 같은 제반결점을 해소하고자 이루어진것으로서, 본고안의 목적은 밧테리에 충전되어 있는 DC전원에 의해 자력을 발생하는 전자석과 회전자인 영구자석간의 자계에 의해 회전자가 회전하는 로타(ROTOR)방식으로 선반위에 놓인 물건을 회전시키는 회전식 선반대의 구동회로를 제공하는데 있다.Therefore, the present invention was made to solve the above-mentioned shortcomings, and the purpose of this paper is to rotate the rotor by the magnetic field between the electromagnet that generates the magnetic force by the DC power charged in the battery and the permanent magnet which is the rotor. It is to provide a drive circuit of a rotary shelf for rotating the objects placed on the shelf in a manner.

상기의 목적을 달성하기 위하여 본고안의 회전식 선반대의 구동회로는 선반을 회전시키는 회전력을 발생하는 회전자와 이 회전자와 서로 대향되게 설치되어 회전자를 자계로 회전시키는 전자석과, 밧테리에서 출력되는 DC를 받아 일정한 레벨을 갖는 펄스를 출력하여 상기 전자석에 공급하는 펄스발생부로 구성됨을 특징으로 한다.In order to achieve the above object, the driving circuit of the rotary shelf of the present invention is provided with a rotor that generates rotational force for rotating the shelf, an electromagnet for rotating the rotor in a magnetic field, and a DC output from the battery. It is characterized in that it consists of a pulse generator for supplying the electromagnet by outputting a pulse having a constant level.

이하, 예시된 도면을 통하여 본고안을 더욱 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the illustrated drawings.

본고안에 따른 회전식 선반대의 구동회로는 제2도 및 제3도에 도시된 바와같은 실시예를 가진다.The driving circuit of the rotary shelf according to the present invention has an embodiment as shown in FIGS. 2 and 3.

제2도에 의하면 회전식 선반대의 구동회로는 밧테리에서 출력되는 DC전원을 "온" 또는 "오프"하는 전원스위치(10)의 작동에 따라 공급되는 DC전류를 입력으로 하여 일정한 레벨을 갖는 펄스를 발생하도록 멀티바이브레이터로 구성된 제1펄스발생부(20)와, 상기 제1펄스발생부(20)에서 출력되는 펄스에 의해 자력을 발생하는 제1전자석(30)과, 상기 전원스위치(10)의 작동에 따라 공급되는 DC전류를 입력으로하여 제1펄스발생부(20)에서 출력되는 펄스와 레벨이 서로 반대인 펄스를 출력하도록 멀티바이 브레이터로 구성된 제2펄스발생부(40)와, 상기 제2펄스발생부(40)에서 출력되는 펄스에 의해 자력을 발생하는 제2전자석(50)과, 상기 제1, 2전자석(30)(50)과 서로 대향되게 설치되어 자계에 의해 회전하는 회전자(60)으로 구성된다.According to FIG. 2, the driving circuit of the rotary shelf generates a pulse having a constant level by inputting the DC current supplied according to the operation of the power switch 10 for turning on or off the DC power output from the battery. The first pulse generator 20 configured as a multivibrator, the first electromagnet 30 for generating magnetic force by a pulse output from the first pulse generator 20, and the operation of the power switch 10. A second pulse generator 40 configured as a multivibrator to output a pulse having a level opposite to that of the pulse output from the first pulse generator 20 by inputting a DC current supplied according to The second electromagnet 50, which generates magnetic force by the pulse output from the two-pulse generator 40, and the first and second electromagnets 30, 50, which are installed to face each other and rotate by a magnetic field. It consists of 60.

한편, 제3도에 도시된 회전식 선반대의 구동회로는 제1펄스발생부(20)에서 출력되는 펄스와, 이 펄스의 레벨을 반전시키는 인버터(20A)의 출력펄스를 제1, 2 전자석(30)(50)에 공급하여 회전자(60)을 회전시키도록 되어 있다.On the other hand, the driving circuit of the rotary shelf shown in FIG. 3 uses the first and second electromagnets 30 to output the pulses output from the first pulse generator 20 and the output pulses of the inverter 20A for inverting the levels of the pulses. The rotor 60 is rotated by supplying it to the head 50.

상기 회전자(60)는 그 상측단이 긴고정홈에 회전자유롭게 삽입되어 있는 축(60D)에 중심이 삽입고정된 제1, 2 영구자석(60A)(60B)과, 상기 제2영구자석(60B)과 극성이 같고 일면이 고정된 제3영구자석(60C)의 중심홈에 상기 축(60D)의 하측단을 안착시켜 구성된다.The rotor 60 has first and second permanent magnets 60A and 60B whose center is inserted into and fixed to a shaft 60D, the upper end of which is freely inserted into the long fixing groove, and the second permanent magnet ( 60B) is configured by seating the lower end of the shaft (60D) in the center groove of the third permanent magnet (60C) of the same polarity and fixed one surface.

상기한 바와같은 구성을 가진 회전식 선반대 구동회로의 작동관계를 전체적으로 설명하면 다음과 같다.Referring to the overall operation of the rotary shelf drive circuit having the configuration as described above are as follows.

제1도는 본고안을 채용한 회전식 선반대의 전체사시도이고, 제2도 및 제3도는 본고안에 따른 회전식 선반대 구동회로의 실시예시도이다.1 is an overall perspective view of a rotary shelf according to the present invention, and FIGS. 2 and 3 are exemplary views of a rotary shelf driving circuit according to the present invention.

제2도에 도시되어 있는 전원스위치(10)를 사용자가 "온"하면 밧테리(도면에 도시되지않음)에서 출력되는 DC전류가 전원스위치(10)를 통해 제1, 2 펄스발생부(20)(40)에 각각 공급된다.When the user "on" the power switch 10 shown in FIG. 2, the DC current output from the battery (not shown) is first and second pulse generators 20 through the power switch 10. 40 is supplied to each.

상기 제1, 2 펄스발생부(20)(40)는 멀티바이브 레이터로 구성되어 있으며 그 출력단은 서로다른 트랜지스터의 콜렉터단자가 된다.The first and second pulse generators 20 and 40 are configured as multivibrators, and their output terminals are collector terminals of different transistors.

따라서 제1, 2 펄스발생부(20)(40)의 DC전류가 공급되면 상기 제1, 2 펄스발생부(20)(40)의 출력신호는 서로 다른 레벨을 가진 펄스가 되어 제1,2 전자석(30)(50)에 공급되므로 제1전자석(30)과 제2전자석(50)에서 발생하는 N, S 자력은 서로교번으로 발생되기 때문에 회전자(60)는 회전하게 된다.Therefore, when the DC current of the first and second pulse generators 20 and 40 is supplied, the output signals of the first and second pulse generators 20 and 40 become pulses having different levels, and thus, the first and second pulse generators 20 and 40 are provided. Since the N and S magnetic forces generated in the first electromagnet 30 and the second electromagnet 50 are alternately generated because they are supplied to the electromagnets 30 and 50, the rotor 60 rotates.

이와같이 회전자(60)가 회전하게 되면 중심축(60D)에 벨트(도면에 도시되지 않음)로 결합된 풀리와 기어(도면에 생략)가 구동되어 이와 치합된 제1도의 선반(A)이 회전하게 된다.When the rotor 60 rotates in this way, the pulley and gear (not shown) coupled to the central shaft 60D by a belt (not shown) are driven to rotate the lathe A of FIG. Done.

상술한 바와같이 작동하는 본고안에 의하면 밧테리에 충전되어 있는 DC전류를 이용하여 물건을 회전시키는 선반을 장시간 회전시킬수 있는 장점이 있다.According to the present invention operating as described above there is an advantage that can be rotated for a long time the shelf for rotating the object by using the DC current charged in the battery.
