본 고안은 형광체를 도포 공정중 패널 둘레면의 잔여 형광체를 회수하기 위한 장치에 관한 것으로 더욱 상세히는 원심력에 의하여 패널 내면에 적정 두께로 도포되고 난 여분의 형광체를 회수하기 위한 장치에 관한 것이다.The present invention relates to a device for recovering the remaining phosphor on the peripheral surface of the panel during the phosphor coating process, and more particularly, to a device for recovering the extra phosphor that has been applied to the inner surface of the panel by a centrifugal force at an appropriate thickness.

주지하는 바와 같이 칼라음극선관을 제조하기 위하여 3색의 형광체를 도포하여야 하는 것이며, 이를 위하여 형광체를 원심력에 의하여 적정 두께로 도포하고 난 다음 잔여 형광체가 흘러 내리므로 흡수성이 우수한 해면체로 된 롤러를 사용하여 닦아내고 있는 것이며, 이러한 상태를 제1도로 도시하였다.As is well known, in order to manufacture a color cathode ray tube, three colors of phosphors should be applied. For this purpose, after applying the phosphors to an appropriate thickness by centrifugal force, the remaining phosphors flow down to use a sponge made of sponges having excellent absorbency. This state is shown in FIG. 1.

그러나 형광체는 점성이 있는 것이어서 해면체로 된 롤러로 닦아낸 후에도 계속하여 잔류 형광체가 흘러내리는 것이므로 캐리어와 콘베이어등에 묻게 되어 청정 상태가 유지되어야 할 작업장이 오염되는 문제점이 있을 뿐만 아니라 다른 패널을 오염시키게 되어 불량률을 증가시키는 문제점이 있는 것이다.However, since the phosphor is viscous and the residual phosphor continues to flow after wiping with a roller made of spongy bodies, the phosphor and the conveyor will be polluted and contaminate other panels. There is a problem of increasing the defective rate.

또한 3색의 형광체 중에 특히 적색의 형광체는 그 가격이 고가임에도 불구하고 효과적인 회수 수단이 마련되어 있지 않아 그대로 폐기함으로써 경제적인 손실을 입게 되는 문제점이 있는 것이다.In addition, although the red phosphors among the three color phosphors are expensive, there is a problem in that they are economically lost because they are disposed of as they are not provided with an effective recovery means.

상술한 종래의 문제점을 감안하여 본 고안의 목적은 도포공정이 완료된 상태의 패널 내면의 잔여 형광체를 닦아냄과 동시에 세척을 실시하도록 하며 세척수를 회수하여 형광체를 회수할 수 있도록 하는 패널 내측 둘레면 형광체 회수장치를 제공하는 것이다.In view of the above-mentioned conventional problems, an object of the present invention is to wipe the remaining phosphor on the inner surface of the panel in a state where the coating process is completed, and to perform the washing at the same time, and to recover the phosphor by recovering the washing water. It is to provide a recovery device.

상술한 목적을 달성하기 위하여 본 고안은 실린더의 피스톤 로드 작동에 의하여 패널 둘레면에 접하거나 분리되는 습동로드를 갖는 해면체 롤러로 된 공지의 패널 둘레면 닦음 장치에 있어서,In order to achieve the above object, the present invention provides a known panel peripheral surface wiping device of a sponge body roller having a sliding rod in contact with or separated from the panel peripheral surface by a piston rod operation of a cylinder,

습동로드의 일측에 추가로 설치된 승강 실린더와 승강실린더의 피스톤 로드에 의하여 간격유지봉과 흡입노즐 그리고 세척수 공급노즐이 일체로 승강되도록 하고, 이러한 흡입노즐에 스트레이너(STRAINER)와 진공펌프를 설치하여서 된 패널 내측 둘레면 형광체 회수장치를 제안한다.The lifting rod, suction nozzle and washing water supply nozzle are raised and lowered by the lifting cylinder and the piston rod of the lifting cylinder which are installed on one side of the sliding rod. An inner peripheral surface phosphor recovery device is proposed.

상술한 구성에 의하여 본 고안은 형광체가 도포완료된 후 흘러내리는 잔여 형광체와 둘레에 묻은 형광체를 흡입노즐과 해면체로 된 롤러에 의하여 흡입하고 닦아냄은 물론이려니와, 간격유지봉에 의하여 최적 간격을 유지하여 높은 흡입효율을 유지하고, 세척수를 공급하여 형광체의 유동성을 증가시켜 형광체가 더욱 효과적으로 흡입될 수 있도록 하는 것이어서, 패널 내측과 둘레의 잔여 형광체를 거의 완벽하게 흡입하여 관련 설비나 다른 패널을 오염시킴에 따른 불량품의 발생을 방지할 수 있게 되는 것일 뿐만 아니라 고가의 형광체를 회수하여 재활용할 수 있게 됨으로써 경제적인 이득을 얻을 수 있는 유용한 효과를 제공한다.By the above-described configuration, the present invention sucks and wipes the remaining phosphor flowing down after the phosphor is applied and the phosphor deposited on the periphery by the suction nozzle and the spongy roller, and of course, maintaining the optimum interval by the gap retaining rod. It maintains high suction efficiency and supplies washing water to increase the fluidity of the phosphors so that the phosphors can be sucked more effectively.It almost completely inhales the remaining phosphors inside and around the panel to contaminate related equipment or other panels. In addition to being able to prevent the occurrence of defective products, it is possible to recover and recycle expensive phosphors, thereby providing a useful effect of obtaining economic benefits.

이하 첨부된 도면을 참조하여 본 고안을 더욱 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제2도에 본 고안에 의한 형광체 회수장치를 도시하였으며, 이에서 볼 수 있는 바와 같이 본 고안은 기대위에 고정된 프레임에 실린더(1)에 의하여 경사상으로 승강하는 습동로드(3)를 구동하고 습동로드(3)의 선단에는 해면체 롤러(4)를 설치하여서 된 공지의 패널 둘레면 닦음 장치에 있어서,2 shows the phosphor recovery apparatus according to the present invention, and as can be seen from the present invention, the present invention drives a sliding rod 3 that is inclined and lifted by a cylinder 1 to a frame fixed on an expectation. In the well-known panel circumferential surface wiping device which provided the sponge roller 4 at the front-end | tip of the sliding rod 3,

간격유지봉(6)에 인접하여 설치된 흡입노즐(7)과 흡입노즐(7)의 측부에 인접하여 설치된 세척수 공급노즐(14)과, 흡입노즐(7)과 진공펌프(13)사이에 두조의 진공라인(12)과 스트레이너(8,8')와 개폐밸브(9,9')를 선택적으로 개폐할 수 있도록 하여서 된 것이다.Two sets of suction nozzles (7) provided adjacent to the space retaining rod (6) and washing water supply nozzles (14) provided adjacent to the side of the suction nozzle (7), and between the suction nozzle (7) and the vacuum pump (13). The vacuum line 12, the strainers (8, 8 ') and the on-off valves (9, 9') to be opened and closed selectively.

이와 같이 된 본 고안은 먼저 일측 진공라인(12)의 개폐 밸브(9)를 잠그고 타측 진공라인(12')의 개폐 밸브(9')는 열어두어야 하는 것이다.According to the present invention as described above, the on / off valve 9 of one side vacuum line 12 should be locked and the on / off valve 9 'of the other side vacuum line 12' should be left open.

이와 같이 한후 패널(11)이 캐리어 헤드에 척킹된 상태로 모우터에 의하여 회전하고 이때 실린더(1)를 작동시킴으로써 습동로드(3)가 상승하여 롤러(4)가 패널(11)의 둘레면에 닿게 되는 것이다.After this, the panel 11 is rotated by the motor while the panel 11 is chucked to the carrier head. At this time, the sliding rod 3 is raised by operating the cylinder 1 so that the roller 4 is placed on the circumferential surface of the panel 11. Will be reached.

이러한 상태에서 패널(11)이 회전하게 됨에 따라 패널(11)의 둘레면이 닦이게 되는 것이고, 이때 본 고안에서는 승강 실린더(2)가 작동하여 그 피스톤 로드(5)가 하강함으로써 이에 연결된 승강간이 하강하면서 간격유지봉(6)이 먼저 패널(11) 내면에 닿게 되는 것이다.In this state, as the panel 11 rotates, the circumferential surface of the panel 11 is wiped, and in this embodiment, the lifting cylinder 2 is operated so that the piston rod 5 descends so that the lifting leg connected thereto is While falling, the gap retaining rod 6 will first touch the inner surface of the panel 11.

이러한 위치는 흡입노즐(7)과 세척수 공급노즐(14)이 패널(11) 내면과 적당한 간격을 두고 있는 상태이며 이러한 상태에서 흡입노즐(7)에 진공을 가함으로써 흘러내리는 잔여 형광체를 흡입할 수 있는 것이고, 아울러 세척수 공급노즐(14)에 의하여 패널(11) 내면에 세척수를 흐르게 함으로써 형광체의 점도가 저하되고 흡입효율이 향상될 수 있는 것이어서 패널(11) 내면의 형광체가 효과적으로 흡입노즐(7)에 의하여 흡입될 수 있는 것이다.This position allows the suction nozzle 7 and the washing water supply nozzle 14 to be spaced apart from the inner surface of the panel 11 in such a state that the residual phosphor flowing down by applying vacuum to the suction nozzle 7 can be sucked. In addition, by flowing the washing water to the inner surface of the panel 11 by the washing water supply nozzle 14, the viscosity of the phosphor can be lowered and the suction efficiency can be improved, so that the phosphor on the inner surface of the panel 11 is effectively suction nozzle (7) It can be inhaled by.

이와 같이 하여 흡입노즐(7)에 의하여 효과적으로 흡입된 형광체는 먼저 스트레이너(8)를 통과하게 되는바, 스트레이너(8)는 그 내부가 진공라인(12)에 비하여 광대한 상태이므로 압력이 저하되어 중량이 있는 형광체는 낙하하게 되는 것이어서 배출밸브(10)로 배출될 수 있는 것이고, 물과 공기는 출구로 진공펌프(13)에 의하여 흡인되어 외부로 배출될 수 있는 것이다.In this way, the phosphor effectively sucked by the suction nozzle 7 first passes through the strainer 8, and the strainer 8 has a larger pressure than the vacuum line 12 so that the pressure decreases and the weight is reduced. This phosphor is to be dropped to be discharged to the discharge valve 10, water and air is to be sucked by the vacuum pump 13 to the outlet can be discharged to the outside.

이와 같이 하여 본 고안은 패널(11) 내측의 잔여 형광체를 효과적으로 흡입하여 공정 진행중 다른 패널(11)이나 컨베이어등에 묻지 않게 되는 것이어서 오염으로 인한 불량이 없게 되며 이러한 상태로 작업을 진행하다보면 일측 진공라인(12)의 스트레이너(8)에 형광체가 채워지게 되고,In this way, the present invention effectively sucks out the remaining phosphor inside the panel 11 so as not to be stained with the other panel 11 or the conveyor during the process, so that there is no defect due to contamination. The strainer 8 of (12) is filled with phosphors,

이러한 상태가 되면 이번에는 타측 진공라인(12')의 개폐밸브(9')를 열고 일측 진공라인(12)의 개폐밸스(9)를 잠그며 잠긴 측의 스트레이너(8)의 배출밸브(10)를 열어 형광체를 회수함으로써 재활용할 수 있게 되는 것이어서 경제적인 이득을 제공하게 된다.In this state, this time, the open / close valve 9 'of the other vacuum line 12' is opened, the open / close valve 9 of the one vacuum line 12 is locked, and the discharge valve 10 of the strainer 8 of the locked side is closed. It can be recycled by opening and recovering the phosphor, which provides economic benefits.

이러한 과정으로 타측 스트레이너(8')에 형광체가 채워지면 처음의 상태와 같이 일측 진공라인(12)의 개폐밸브(9)를 열고 타측 진공라인(12')의 개폐밸브(9')를 잠근 후 타측 스트레이너(8')의 형광체를 배출시켜 회수하는 과정을 반복함으로써 패널(11)의 잔여 형광체를 흡입하고 회수하는 일련의 공정을 반복할 수 있게 되는 것이다.When the phosphor is filled in the other strainer (8 ') by this process, as shown in the initial state, the on-off valve 9 of one vacuum line 12 is opened and the on / off valve 9' of the other vacuum line 12 'is closed. By repeating the process of discharging and recovering the phosphor of the other strainer 8 ′, a series of processes of sucking and recovering the remaining phosphor of the panel 11 can be repeated.
