The present invention relates to a device for transmitting power and signals to each other, and more particularly, to a device for supplying power and signals to a logistics pallet receiving power by rolling contact with a power supply rail.

PDP 생산 공정에서 PDP 패널은 통상 연속생산라인(Continuous Production line) 상을 이동하며 순차적으로 제조되는 바, 에이징 공정도 연속생산라인상에서 이루어지게 된다.In the PDP production process, PDP panels are typically manufactured sequentially while moving on a continuous production line, and thus an aging process is performed on the continuous production line.

에이징 공정 전에는 상,하판 내부에 불순가스가 제거되고 진공이 형성되며 방전가스(Ne+Ar, Ne+Xe)가 주입된다. 에이징 공정은 초기방전을 통하여 전자소자 및 패널 내부 벽면물질을 안정화시키며 광학적, 전기적 성능을 유지하는 목적으로 장시간 동안 수행되는 필수공정이다.Before the aging process, impurity gas is removed from the upper and lower plates, a vacuum is formed, and discharge gas (Ne + Ar, Ne + Xe) is injected. The aging process is an essential process that is performed for a long time for the purpose of stabilizing the electronic material and the inner wall material of the panel through the initial discharge and to maintain the optical and electrical performance.

이때 전원 및 신호인가 목적으로 전원공급레일로부터 전원을 인가받는 전원및 신호인가장치(electric brush)가 설치된다. 종래의 전원 및 신호인가장치는 도 1의 (a)와 같은 미끄럼접촉 방식과 (b)와 같은 스프링 접촉방식을 사용하였다. 미끄럼접촉 방식은 접촉부(2)를 휨 탄성력으로 전원공급레일(5)에 접촉시키는 방법이고, 스프링 접촉방식은 접촉부(2')를 코일스프링(3)의 반발력으로 전원공급레일(5)에 접촉시키는 방법이다.At this time, a power and a signal applying device (electric brush) receiving power from the power supply rail for power and signal application purposes are installed. In the conventional power supply and signal application device, a sliding contact method such as (a) of FIG. 1 and a spring contact method of (b) are used. The sliding contact method is a method of contacting the contact part 2 to the power supply rail 5 with a bending elastic force, and the spring contact method is to contact the power supply rail 5 with the contact part 2 'by the repulsive force of the coil spring 3. This is how you do it.

그러나 이러한 방식들은 접촉부(2,2')에서 전기스파크가 발생하고, 전기스파크에 의한 끄을음 오염이 발생되고, 고착된 오염물을 제거하기 위한 청소작업이 요구되었다. 따라서 통전의 불량으로 에이징 공정의 수율을 저하시키는 요인으로 작용하였다.However, these methods require electric sparks at the contacts 2, 2 ', trailing contamination by the electric sparks, and cleaning operations to remove the contaminated contaminants. Therefore, it was a factor that lowers the yield of the aging process due to poor current supply.

따라서 본 발명은 상기와 같은 사정을 감안하여 창출된 것으로, 전원공급레일에 구름 접촉하여 전원을 인가받아 물류 파렛트(Pallet)에 공급토록 함으로써 스파크 발생이 없고 통전효율이 향상되도록 한 피.디.피 에이징 팰릿의 전원 및 신호인가장치를 제공함에 그 목적이 있다.Therefore, the present invention was created in view of the above circumstances, and by supplying power to the logistics pallet by contacting the power supply rail with a cloud, it is possible to improve the efficiency of electricity supply without sparking.

본 발명은 도 2와 같이 전원공급레일(5)에 접촉하여 인가받은 전원을 이송되는 파렛트(100)에 공급하는 전원 및 신호인가장치(10)를 제공한다.The present invention provides a power supply and signal applying device 10 for supplying the applied power to the pallet 100 to be transferred to contact the power supply rail (5) as shown in FIG.

전원 및 신호인가장치(10)는 도2 내지 도 4와 같이 파렛트(100)측에 설치되는 통전몸체(12)가 구비된다. 통전몸체(12)는 전도성 몸체로서 일예로, 동합금으로 제작될 수 있다. 통전몸체(12)에는 팰릿(100)측에 장착되기 위해 조립용 나사구멍(12a)이 형성되어 있고, 나사구멍(12a)의 양쪽으로 고정용 핀홀(12b)이 형성되어 있다.Power supply and signal applying device 10 is provided with an energizing body 12 is installed on the pallet 100 side as shown in FIG. The energizing body 12 may be made of, for example, a copper alloy as the conductive body. In the energizing body 12, an assembling screw hole 12a is formed to be mounted on the pallet 100 side, and fixing pinholes 12b are formed at both sides of the screw hole 12a.

통전몸체(12)에는 지지축(14)이 강제 삽입되어 있다. 지지축(14)은 통전몸체(12)에 모따기가 이루어진 모서리측 라운드 홈(11)에 설치되어 있다. 지지축(14)에는 회전 가능하게 삽입되어 상기 전원공급레일(5)에 구름 접촉되는 롤링수단으로 베어링(16)이 라운드 홈(11)에 위치되어 있다.The support shaft 14 is forcibly inserted into the energizing body 12. The support shaft 14 is provided in the corner side round groove 11 in which the chamfer was made to the electricity supply body 12. As shown in FIG. The bearing 16 is located in the round groove 11 by a rolling means rotatably inserted into the support shaft 14 and rolling contact with the power supply rail 5.

롤링수단은 외륜과 내륜을 포함하는 베어링(16)으로 구성되거나 다른 예로, 원형단면의 롤러로 구성될 수 있다. 이때 롤러와 베어링(16)은 통전 소재로 제작되 며, 롤러와 베어링(16)의 내,외륜은 통전율을 향상시키기 위해 코팅이 이루어질 수 있다.The rolling means may consist of a bearing 16 comprising an outer ring and an inner ring, or in another example, a roller of circular cross section. At this time, the roller and the bearing 16 is made of a conductive material, the inner and outer rings of the roller and the bearing 16 may be coated to improve the electrical conductivity.

통전몸체(12)에는 도선(30)을 연결하기 위해 접속수단이 구비된다. 접속수단은 예로, 볼트나 잭이 될 수 있다.The energizing body 12 is provided with connecting means for connecting the conductive wire 30. The connecting means can be, for example, bolts or jacks.

본 실시예에서 접속수단은 통전몸체(12)에 간섭제거용 안전바(20)를 고정하기 위한 볼트(18)로 대체하였다. 간섭제거용 안전바(20)는 전원인가장치(10)의 이동 간섭을 없애기 위한 것이다.In this embodiment, the connecting means has been replaced by a bolt 18 for fixing the safety bar 20 for removing interference to the energizing body (12). The safety bar 20 for removing interference is for removing the moving interference of the power applying device 10.

이와 같이 구성된 전원 및 신호인가장치(10)는 도 2와 같이 파렛트(100)측에 나사(미도시)를 통해 장착되고, 베어링(16)은 그 외주면이 전원공급레일(5)에 선접촉된다.The power supply and signal applying device 10 configured as described above is mounted on the pallet 100 side with screws (not shown) as shown in FIG. 2, and the bearing 16 has its outer circumferential surface in line contact with the power supply rail 5. .

이 상태에서 팰릿(100)이 이송기구에 의해 화살표(F) 방향으로 이송되어지면 베어링(16)의 외륜이 전원공급레일(5)에 선접촉 상태에서 구름운동을 하게 된다. 따라서 전원공급레일(5)로부터 베어링(16), 통전몸체(12), 도선(30)의 순으로 전원을 인가받게 된다.In this state, when the pallet 100 is transferred in the direction of the arrow F by the transfer mechanism, the outer ring of the bearing 16 performs rolling motion in the line contact state with the power supply rail 5. Therefore, power is applied from the power supply rail 5 to the bearing 16, the energizing body 12, and the conducting wire 30 in this order.

이같이 베어링(16)은 미끄럼접촉이 아닌 구름접촉으로 전원 및 신호를 인가받아 스파크가 발생되지 않는다. 따라서 종래와 같이 그을음의 오염이 없고 이로 인한 청소 작업이 불필요해진다. 또한, 원활한 통전으로 에이징 공정의 품질이 향상되는 것이다.As such, the bearing 16 receives the power and the signal through the rolling contact, not the sliding contact, and does not generate the spark. Therefore, there is no soot contamination as in the prior art, and thus the cleaning operation is unnecessary. In addition, the quality of the aging process is improved by smooth energization.

또한 교류와 직류 등 전원 수급과 시그날(SIGNAL)의 송수신용으로 적용할 수 있어 PDP 패널의 규격변경이나 표준 변경시에도 대응이 가능하여 부품 변경없이 활 용할 수 있다.In addition, it can be used for supplying and receiving signals such as AC and DC and transmitting / receiving signals, so it can be used even when changing specifications or standards of PDP panels, and can be utilized without changing parts.

이때 통전몸체(12)의 설치위치는 이동 동작 방향에 따라 수직, 수평 구조도 가능하고, 통전몸체(12)의 형상은 현장 설비의 상황에 능동적으로 대응이 가능하도록 할 수 있다.At this time, the installation position of the energizing body 12 may be vertically and horizontally structured according to the movement direction, and the shape of the energizing body 12 may enable active response to the situation of the field equipment.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
