본 고안은 프린터나 전자복사기 등에 내장되어 있는 감광체위의 잔류토우너를 제거하기 위한 클리이닝 장치에 관한 것이다.The present invention relates to a cleaning device for removing residual toner on a photosensitive member embedded in a printer or an electronic copying machine.
종래의 감광체의 클리이닝 장치는, 예로 일본국 특공소 55-49313호 공보에 기재되어 있다.The cleaning apparatus of the conventional photosensitive member is described in Unexamined-Japanese-Patent No. 55-49313, for example.
이 공보에 기재되어 있는 클리이닝 장치는, 전자복사기의 회전드럼의 외주면에 대향하여 접하는 토우너 긁어 내림용 브레이드와, 상기한 드럼축과 평행으로 연장하는 지지축과, 이 지지축위에 회동이 자재롭게 유동가능하게 끼워지지된 안내판 유지부재와 이 유지부재에 보호 유지된 그 상단 가장자리가 상기한 브레이드보다 하방으로 상기한 드럼의 외주면에 대향하여 접하는 토우너 안내판과, 상기한 지지축에 의하여 상기한 토우너 안내판에 충격을 가하기 위한 충격인가 기구로 되는 것을 특징으로 한 것이었다.The cleaning apparatus described in this publication includes a toner scraping braid which faces the outer circumferential surface of a rotating drum of an electronic copying machine, a support shaft extending in parallel with the drum shaft, and a rotational movement on the support shaft. A guide plate holding member which is fitted to be able to flow smoothly, a top edge of which is protected and held by the holding member, the toner guide plate which faces the outer circumferential surface of the drum in a lower direction than the braid; It was characterized by being an impact application mechanism for impacting the toner guide plate.
상술한 바와같이, 종래의 기술에서는, 토우너 안내판에 충격이 가하여지는 것인바, 이 토우너 안내판에 충격이 가하여지면, 이 충격이 감광체에도 전달된다.As described above, in the prior art, an impact is applied to the toner guide plate. When an impact is applied to the toner guide plate, the impact is transmitted to the photosensitive member.
그러면, 감광체의 표면도 반복하여 충격을 받아 이 충격에 의하여 감광체가 열화하여, 그 수명이 단축될 염려가 있었다.As a result, the surface of the photoconductor was repeatedly impacted, and thus the photoconductor was deteriorated by the impact, and the life of the photoconductor was shortened.
본 고안은, 상기한 문제점을 해결하기 위하여, 자유단부가 감광체의 표면에 미끄러지도록 접하여 감광체위의 토우너를 제거하는 클리이닝 브레이드와, 이 클리이닝 브레이트의 하방에 구비되어, 감광체에서 제거된 토우너를 토우너 수납부에 안내하는 안내 브레이드와, 상기 토우너 수납부에 설치된 토우너 배출용의 스크루 콘베이어가 구비되어 있는 클리이닝 장치에 있어서, 상기한 안내브레이드의 내측에 부착한 토우너를 상기 토우너 수납부에 낙하시켜기 위한 상기 스크루베이어의 스쿠루에 맞닿고, 이 스크루콘베이어의 회전에 따라 상기 안내브레이드 근방위치에서 상하방향으로 요동이 일어나는 토우너 긁어 내림부재가 장착되어 있는 것을 특징으로 하는 감광체의 클리이닝 장치이다.The present invention, in order to solve the above problems, a cleaning braid for removing the toner on the photosensitive member by contacting the free end to slide on the surface of the photosensitive member, and a toner provided below the cleaning plate and removed from the photosensitive member A cleaning device comprising a guide braid for guiding a toner storage unit and a screw conveyor for discharging toners provided in the toner storage unit, wherein the toner attached to the inside of the guide blade is the number of toners. A toner scraping member is mounted, which is brought into contact with the screw of the screw conveyor for dropping to a soldering section, and which has a toner scraping member which swings up and down in the vicinity of the guide blade according to the rotation of the screw conveyor. It is a cleaning device.
본 고안에서는 안내브레이드의 내측에 토우너 긁어 내림부재가 요동이 자재하게 장착되어 있으므로, 이 토우너 긁어 내림부재를 요동시키면 안내브레이드의 내측에 부착하여 있는 잔류토우너가 긁어내림되어 토우너 수납부에 수납된다.In the present invention, since the toner scraping member is rocked on the inside of the guide blade, the swinging of the toner scraping member causes the residual toner attached to the inside of the guide blade to be scraped off to the toner storage unit. It is stored.
본 고안의 실시예를 첨부도면에 의거하여 상세히 설명한다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
(1)은 플라스틱제의 바구리체로 그 개구(2)에 대향하는 부위에, 감광체 드럼(3)이 위치하고 있다 (제1도 참조).(1) is a plastic basket and the photosensitive drum 3 is located in the site | part which opposes the opening 2 (refer FIG. 1).
전기한 개구(2)의 중앙부에는, 감광체드럼(3)의 회전축선의 긴방향과 평행인 방향으로 길게 존재하는 공지의 클리이닝 브레이드(4)가 구비되어 있다.In the center part of the opening 2 mentioned above, the well-known cleaning braid 4 which exists long in the direction parallel to the longitudinal direction of the rotation axis of the photosensitive body drum 3 is provided.
상기한 바구니체(1)의 내부 바닥에는 통형상의 폐토우너 수납부(5)가 형성되어 있으며, 이 폐토우너 수납부로(5)내에 상기한 클리이닝 브레이드(4)의 긴방향과 평행인 방향으로 폐토우너(6)을 이송하기 위한 스크루 콘베이어(screw conveyor)(7)이 구비되어 있다.The inner bottom of the basket body 1 is formed with a cylindrical waste toner storage portion 5, and the longitudinal direction of the cleaning braid 4 described above in the waste toner storage passage 5 A screw conveyor 7 for transporting the waste toner 6 in the parallel direction is provided.
폐토우너 수납부(5)의, 감광체드럼(3)측의 측벽(8)의 외면에는, 상기한 클리이닝브레이드(4)의 긴방향과 평행인 방향으로 길게 존재하는 안내브레이드(9)가 고착되어 있다.On the outer surface of the side wall 8 of the photoconductor drum 3 side of the waste toner accommodating part 5, the guide blade 9 which exists long in the direction parallel to the longitudinal direction of the said cleaning blade 4 is present. It is stuck.
이 안내브레이드(9)는, 클리이닝브레이드(4)에 의하여 감광체 드럼(3)에서 제거된 폐토우너(잔류토우너)(6)을 폐토우너 수납부(5)내부에 안내하기 위한 것이다.This guide blade 9 is for guiding the waste toner (residual toner) 6 removed from the photosensitive drum 3 by the cleaning blade 4 into the waste toner storage 5. .
또, 폐토우너 수납부(5)의 감광체드럼(3)과 반대측의 어깨부분에는 제2도에 표시한 바와같은, 다수의 절곡단부(10)이 상방으로 절곡된 빗형상의 토우너 긁어내림부재(11)의 기부가 고착되어 있다.In addition, a comb-shaped toner scraping, in which a plurality of bent ends 10 are bent upwards, as shown in FIG. 2, is disposed on the shoulder portion opposite to the photosensitive drum 3 of the waste toner storage portion 5. The base of the member 11 is fixed.
이 토우너 긁어내림 부재(11)의 각 절곡단부(10)은 상기한 안내브레이드(9)의 내측의 근방에까지 길게 나와있으며 그 각 수평걸이부(12)는 상기한 스크루 콘베이어(7)의 스크루(13)에 맞닿아 있다.Each bent end 10 of the toner scraping member 11 extends out to the inner side of the guide blade 9 described above, and each of the horizontal hangers 12 is a screw of the screw conveyor 7 described above. (13) abuts.
이 스크루(13)의 핏치는 상기한 각 수평걸이부(12)의 핏치보다도 길게 형성되어 있으며, 스크루콘베이어(7)이 회전하면, 각각 수평걸이부(12)는 피아노의 건반과 같이 상하 방향으로 요동한다.The pitch of the screw 13 is formed longer than the pitch of the above-described horizontal hook portions 12. When the screw conveyor 7 rotates, the horizontal hook portions 12 each move upward and downward like the keyboard of the piano. Swings.
상기한 토우너 긁어내림부재(11)는, 두께가 0.2 내지 0.3㎜의 폴리에스테르 필름 또는 인 청동판으로 형성되어 있다.The toner scraping member 11 is formed of a polyester film or phosphor bronze plate having a thickness of 0.2 to 0.3 mm.
그리고, 제1도에 있어서, 감광체드럼(3)이 시계방향(화살표 방향)으로 회전하면, 융지에 전사 되지 않고 감광체 드럼(3)에 잔류하는 폐토우너(6)은 클리이닝 브레이드(4)에 의하여 낙하되어 제거된다.In FIG. 1, when the photosensitive drum 3 rotates clockwise (arrow direction), the waste toner 6 remaining on the photosensitive drum 3 without being transferred to the molten paper is cleaned by the cleaning braid 4. It is dropped by and removed.
이와같이 하여서 제거된 폐토우너(6)은 안내브레이드(9)위를 미그러져 내려서 폐토우너 수납부(5)내에 저장되며, 저장된 폐토우너(6)은 스크루콘베이어(7)에 의하여 외부에 배출된다.The waste toner 6 removed in this way is slid down on the guide blade 9 to be stored in the waste toner container 5, and the stored waste toner 6 is stored outside by the screw conveyor 7. Discharged.
그런데, 상기한 스크루콘베이어(7)이 회전하면, 상술한 바와같이 토우너긁어 내림부재(11)의 각 절곡단부(10)이 각각 상하방향으로 요동함으로, 안내 브레이드(9)의 내측에 부착한 폐토우너(6)은 상기한 절곡단부(10)으로 긁어내려 폐토우너 수납부(5)내에 수납된다.However, when the screw conveyor 7 is rotated, each bending end portion 10 of the toner scraping member 11 swings in the vertical direction as described above, and thus is attached to the inside of the guide braid 9. The waste toner 6 is scraped off by the bent end 10 and stored in the waste toner storage 5.
본 고안에서는, 안내브레이드의 내측에, 토우너 긁어내리부재가 요동이 자재롭게 장착되어 있으므로, 이 토우너 긁어내림부재를 요동시키면, 안내브레이드의 내측에 부착하고 있는 잔류 토우너가 낙하되며, 토우너 수납부에 수납된다.In the present invention, since the toner scraping member is freely attached to the inner side of the guide blade, when the toner scraping member is rocked, the remaining toner attached to the inner side of the guide blade falls, and the toner It is stored in a storage unit.
따라서, 안내브레이드에 폐토우너가 퇴적하며, 이 퇴적된 폐토우너가 외부에 낙하하여서 용지를 더럽히는 일이 없다.Therefore, the waste toner is deposited on the guide blades, and the accumulated waste toner does not fall to the outside and soil the paper.
또 안내브레이드에는 충격이 가하여 지지 않으므로 감광체가 손상을 받지않아 긴 수명화에 기여할수 있는 것이다.In addition, because the guide blade is not subjected to impact, the photoconductor is not damaged, which may contribute to a long service life.
