Description

인쇄기의 클리닝장치{Cleaning apparatus for printer}Cleaning apparatus for printer

본 고안은 인쇄기의 클리닝 장치에 관한 것으로서, 상세하게는 기록지에 전사되지 않고 감광매체에 잔류된 현상물질을 제거하면서 수거하는 인쇄기의 클리닝 장치에 관한 것이다.The present invention relates to a cleaning apparatus of a printing press, and more particularly, to a cleaning apparatus of a printing press which is collected while removing a developer remaining on a photosensitive medium without being transferred to a recording sheet.

일반적으로 레이저 프린터나 복사기와 같은 전자사진방식 인쇄기는 노광에 의해 정전 잠상이 형성되어 있는 감광매체에 고체상태의 현상물질인 토너 또는 액체상태의 잉크를 분사시켜 화상을 형성시킨 후, 그 감광 매체와 접촉되어 회전하는 롤러 사이로 기록용지를 통과시킴으로써 원하는 화상을 인쇄할 수 있도록 되어있다.In general, an electrophotographic printing machine such as a laser printer or a copier forms an image by spraying a toner or a liquid ink in a solid developing material on a photosensitive medium on which an electrostatic latent image is formed by exposure, and then forming an image. It is possible to print a desired image by passing the recording paper between the rollers which come into contact and rotate.

이와 같은 인쇄기는 감광매체의 순환에 의해 계속적인 인쇄가 가능하기 위해서는 구현하고자 하는 화상에 대응되어 현상장치에 의해 감광매체에 도포된 현상물질이 전사과정에서 기록용지 또는 기록용지로의 화상전이를 중계하는 매개체로의 100%전이가 이루져야만 한다.In order to enable continuous printing by the circulation of the photosensitive medium, such a printer corresponds to the image to be implemented, and the developing material applied to the photosensitive medium by the developing apparatus relays the image transfer to the recording paper or the recording paper during the transfer process. 100% transition to the medium must be made.

그러나, 전사과정에서 기록용지 또는 상기 매개체로 현상물질의 100%전이는 실질적으로 어렵고, 전사과정이후에도 정도의 차이는 있지만 소량의 현상물질이 감광매체에 잔류하게 된다.However, 100% transfer of the developing material to the recording paper or the medium during the transfer process is substantially difficult, and even after the transfer process, a small amount of the developing material remains on the photosensitive medium.

제거되지 않는 잔류 현상물질을 이후 계속적인 인쇄횟수에 비례하여 누적되어 인쇄화상의 질을 떨어뜨리게 된다. 이와 같은 문제점을 해결하기 위해 종래에는 도 1에 도시된 바와 같이 흡착부재(3)가 그 표면에 마련되어 있는 클리닝봉(2)을 감광매체인 감광드럼(1)에 접촉시켜 잔류현상물질을 제거하였다. 그러나, 감광드럼에 부착된 잔류현상물질의 고착력정도에 따라 다단계로 그 가압력을 조절할 수 없는 단점이 있다.Residual developer that cannot be removed is accumulated in proportion to subsequent prints, resulting in poor print quality. In order to solve such a problem, conventionally, as shown in FIG. 1, the residual member is removed by contacting the cleaning rod 2 provided on the surface of the adsorption member 3 to the photosensitive drum 1 as a photosensitive medium. . However, there is a disadvantage in that the pressing force cannot be adjusted in multiple stages depending on the degree of adhesion of the residual developing material attached to the photosensitive drum.

본 고안은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 감광매체상에 가압유지시키는 가압력을 다단계로 조절하여 현상물질의 고착력 정도에 따라 제거능력을 조절할 수 있도록 하는 인쇄기의 클리닝장치를 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems, and provides a cleaning apparatus of a printing press that can adjust the removal ability according to the degree of adhesion of the developer by adjusting the pressing force held on the photosensitive medium in multiple stages. The purpose is.

이하, 첨부된 도면을 참조하여 본 고안의 바람직한 일 실시예에 따른 전자사진방식 인쇄기의 클리닝 장치를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a cleaning apparatus of an electrophotographic printing press according to an embodiment of the present invention.

도 2는 본 고안의 일실시에 따른 전자사진방식 인쇄기의 클리닝장치를 나타내 보인 단면도이다.2 is a cross-sectional view showing a cleaning apparatus of an electrophotographic printing press according to one embodiment of the present invention.

도면을 참조하면, 인쇄기는 감광드럼(11) 주위의 순환궤도상에 순차적으로 광을 주사하는 광주사유니트(12)와 염료를 분사하는 현상기(13), 그리고 감광드럼(11)에 형성된 화상을 전사시켜 기록용지(14)에 인쇄하는 정착기(15), 그리고 본 발명의 특징부인 클리닝 장치(20)가 마련되어 있다.Referring to the drawings, the printing machine displays images formed on the photoreceptor unit 12 that sequentially scans light on the circular orbit around the photosensitive drum 11, the developer 13 that sprays the dye, and the photosensitive drum 11. A fixing unit 15 which transfers and prints on the recording paper 14 and a cleaning device 20 which is a feature of the present invention are provided.

컬러구현용 인쇄기에서는 색상별로 현상기(13) 및 광주사유니트(12)가 구비되고, 감광드럼(11) 대신에 감광벨트(미도시)가 이용되기도 한다.In the printer for color implementation, a developing device 13 and a photowangsa unit 12 are provided for each color, and a photosensitive belt (not shown) may be used instead of the photosensitive drum 11.

정착기(15)와 광주사유니트(12) 사이에 위치된 클리닝 장치(20)는 블레이드(21)와, 블레이드(21) 상, 하측에서 각각 결합되어 있는 압전소재판(22)(23)과, 압전소재판(22)(23) 각각의 신축을 제어하기 위해 전위(v1)(v2)를 가변인가시킬 수 있는 전원공급제어부(24)를 구비한다. 지지대(26)는 압전소재판(22)(23)의 일측을 고정지지시키기 위한 것이다.The cleaning device 20 located between the fixing unit 15 and the photoreceptor unit 12 includes a blade 21 and piezoelectric material plates 22 and 23 coupled to each other on and below the blade 21, In order to control the expansion and contraction of each of the piezoelectric material plates 22 and 23, a power supply control unit 24 capable of varying the potentials v1 and v2 is provided. The support 26 is for fixing and supporting one side of the piezoelectric material plates 22 and 23.

그리고, 감광드럼(11)에 접촉된 블레이드(21)에 의해 제거되어 떨어지는 잔류 현상물질을 수거하기 위한 수거용기(25)가 마련되어 있다.Then, a collecting container 25 is provided for collecting the residual developing material that is removed and dropped by the blade 21 in contact with the photosensitive drum 11.

그 동작을 살펴보면, 상시에는 전원공급제어부(24)가 각 압전소재판(22)(23)에 전위(v1)(v2)가 인가되지 않도록 전원공급을 차단 또는 해제시킴으로서 블레이드(21)는 그 선단이 감광드럼(11)으로부터 일정거리 이격되어 위치된다. 그리고, 잔류현상물질 제거시에는 전원공급제어부(24)가 어느 한 측 또는 양측의 압전소재판(22)(23)에 전위(v1)(v2)를 인가하게 되는데 이때, 압전소재판(22)(23)의 수축 또는 팽창에 의해 블레이드(21)는 휘어지면서 그 선단이 감광드럼(11)에 접촉된다. 예컨대 상측 압전소재판(23)에는 전위(v2)를 인가하지 않고, 블레이드(21) 하측에 있는 압전소재판(22)에 양(+)의 전위(v1)를 인가하게 되면 하측 압전소재판(22)은 팽창하게 되고, 이 팽창거리에 대응하여 결합된 블레이드(21)는 위쪽으로 휘게 된다. 반대의 경우로서, 하측 압전소재판(22)에는 전위(v1)를 인가하지 않고, 상측 압전소재판(23)에 음(-)의 전위(v2)를 인가하게 되면 상측 압전소재판(23)은 수축하게 되고, 이 수축거리에 대응하여 결합된 블레이드(21)는 위쪽으로 휘게 된다.Looking at the operation, the blade 21 is always the power supply control unit 24 by cutting off or releasing the power supply so that the potential (v1) (v2) is not applied to each piezoelectric material plate (22) (23). The photosensitive drum 11 is positioned at a predetermined distance apart. When the residual developer is removed, the power supply control unit 24 applies the potentials v1 and v2 to the piezoelectric material plates 22 and 23 on either or both sides. In this case, the piezoelectric material plate 22 is applied. By the contraction or expansion of 23, the blade 21 is bent and its tip contacts the photosensitive drum 11. For example, without applying a potential v2 to the upper piezoelectric material plate 23 and applying a positive potential v1 to the piezoelectric material plate 22 under the blade 21, the lower piezoelectric material plate ( 22 is expanded, and the corresponding blade 21 is bent upward in response to this expansion distance. On the contrary, when the potential (v2) is applied to the upper piezoelectric material plate 23 without applying the potential v1 to the lower piezoelectric material plate 22, the upper piezoelectric material plate 23 is applied. Is contracted, and the corresponding blade 21 is bent upward in response to this contraction distance.

따라서, 블레이드(21)의 한측에만 전계인가 유무에 따라 수축 이완 가능한 압전소재판(22)(23)을 결합시키고, 상기 압전소재판(22)(23)에 인가하는 전위를 제어하도록 구성하여도 된다.Therefore, the piezoelectric material plates 22 and 23 that can be contracted and relaxed in accordance with the presence or absence of an electric field are coupled to only one side of the blade 21, and the electric potential applied to the piezoelectric material plates 22 and 23 is controlled. do.

한편, 양측 모두의 압전소재판(22)(23)에 전위(v1)(v2)를 인가하되, 하측에 있는 압전소재판(22)에 양(+)의 전위(v1)를 인가하고, 상측 압전소재판(23)에 음(-)의 전위(v2)를 인가하게 되면 상측 압전소재판(23)의 수축과 하측 압전소재판(22)의 팽창에 의해 블레이드(21)의 휨제어를 강화시킬 수 있다. 특히, 압전소재판(22)(23)은 그 수축 및 팽창길이가 인가되는 전위(v1)(v2)에 대응하기 때문에 블레이드(21)의 힘에 의한 그 선단 위치이동거리를 다단계로 제어할 수 있어 감광드럼(11)에 차등된 가압력을 제공하기가 대단히 용이하다. 통상적인 압전소재판(22)(23)은 인가전위(v1)(v2)변동에 따라 수나노미터 내지 수마이크로미터 단위까지 수축 팽창제어가 가능하기 때문에 접촉에 의한 다단계의 가압력 제어가 용이하게 이루어 질수 있다.On the other hand, the potentials v1 (v2) are applied to the piezoelectric material plates 22 and 23 on both sides, but the positive potential v1 is applied to the piezoelectric material plate 22 on the lower side, and the upper side is applied. When the negative potential (v2) is applied to the piezoelectric material plate 23, the bending control of the blade 21 is enhanced by the contraction of the upper piezoelectric material plate 23 and the expansion of the lower piezoelectric material plate 22. You can. In particular, since the piezoelectric material plates 22 and 23 correspond to the potentials v1 and v2 to which the contraction and expansion lengths are applied, the tip position moving distance due to the force of the blade 21 can be controlled in multiple stages. It is thus very easy to provide a differential pressing force on the photosensitive drum 11. Conventional piezoelectric material plates (22) and (23) can easily control the expansion and contraction of the pressure from several nanometers to several micrometers according to the applied potential (v1) (v2) change, thereby making it easy to control the multi-stage pressing force by contact. I can't.

이를 이용한 효과적인 사용방법으로서는 현상물질 도포 영역에 해당하는 감광드럼(11)의 위치를 판단할 수 있는 별도의 제어기의 도움을 받아 감광드럼(11) 회전시 해당 잔류 현상물질 분포영역이 통과될 때만 블레이드(21)를 접촉시키도록 구동제어하고, 잔류 현상물질 제거를 위한 블레이드(21) 접촉횟수가 설정된 값이 되면 압전소재판(22)(23)에 인가하는 전위(v1)(v2)를 상승시켜 보다 강화된 블레이드(21)의 가압력에 의해 보다 강력한 제거구동을 반복적으로 행하도록 한다.As an effective method of using the blade, only when the residual developer distribution area passes through the rotation of the photosensitive drum 11 with the help of a separate controller that can determine the position of the photosensitive drum 11 corresponding to the developer application region. Drive control to make contact with (21), and the potential (v1) (v2) applied to the piezoelectric material plates (22) and (23) is raised by increasing the contact number of the blade (21) for removing residual developer. The more powerful removal drive is repeatedly performed by the pressing force of the stronger blade 21.

그리고, 반복적인 사용에 의한 블레이드(21)의 마모를 고려하여 압전소재판(22)(23)에 인가하는 전위(v1)(v2)를 증가시킬 수 있기 때문에 일정한 가압력을 유지시킬 수 있다.In addition, since the potentials v1 and v2 applied to the piezoelectric material plates 22 and 23 can be increased in consideration of wear of the blade 21 due to repeated use, a constant pressing force can be maintained.

도 3은 본 고안의 다른 실시예에 따른 전자사진방식 인쇄기의 클리닝장치를 나타내보인 단면도이다.3 is a cross-sectional view showing a cleaning apparatus of an electrophotographic printing press according to another embodiment of the present invention.

도면을 참조하면, 클리닝 장치는 블레이드(31)가 바이메탈판(34)에 결합되어 있고, 상기 바이메탈판(34)에 열을 가할 수 있는 히터(35)가 마련되어 있다. 바이메탈판(34)은 그 일측이 지지대(38)에 고정지지되어 있다. 도 1과 동일기능을 하는 요소는 동일참조부호로 표기되어있다.Referring to the figure, the cleaning device is provided with a heater 35 which is coupled to the bimetal plate 34, the blade 31 is applied to the bimetal plate 34. One side of the bimetal plate 34 is fixed to the support 38. Elements that have the same function as in Fig. 1 are denoted by the same reference numerals.

이와 같은 클리닝장치는 히터(35)에 가하는 전위(v3)의 가변에 의해 바이메탈판(34)의 휨정도 즉, 블레이드(31) 선단의 초기위치로부터 그 선단의 위치이동거리를 제어할 수 있다. 상기 바이메탈판(34)에서 상측금속판(32)은 하측 금속판(33)에 대해 열팽창계수가 작은 물질로 되어 있어 열이 가해지게되면 열팽창계수차이에 의해 휘게된다. 참조부호 37은 제거된 잔류 현상물질 수거용기이다.Such a cleaning apparatus can control the degree of warpage of the bimetal plate 34, that is, the position movement distance of the tip from the initial position of the tip of the blade 31, by varying the potential v3 applied to the heater 35. In the bimetal plate 34, the upper metal plate 32 is made of a material having a small thermal expansion coefficient with respect to the lower metal plate 33, and is bent due to a difference in thermal expansion coefficient when heat is applied. Reference numeral 37 is the residual developer container removed.

바이메탈판(34)을 이용한 블레이드(31)의 제어는 압전소재판(22)(23)( 도 1)보다 응답속도가 떨어지지만, 감광드럼(36)에 접촉되어야 길이가 긴 블레이드(31)를 요구할 경우에는 경제적인 측면에서 우수한 장점을 갖고 있다.The control of the blade 31 using the bimetal plate 34 is slower in response speed than the piezoelectric material plates 22 and 23 (FIG. 1). However, the blade 31 has to be in contact with the photosensitive drum 36 to provide a longer blade 31. If you demand it, you have a good economic advantage.

본 고안에 따른 인쇄기의 클리닝 장치가 제공됨으로써 블레이드의 접촉 및 분리 제어가 용이함은 물론, 접촉상태에서도 차등화된 가압력제어가 가능하여 잔류 현상물질과 같은 이물질 제거를 효과적으로 할 수 있다.Since the cleaning apparatus of the printing machine according to the present invention is provided, it is easy to control the contact and separation of the blades, and the differential pressure control is possible even in the contact state, thereby effectively removing foreign substances such as residual developer.
