Description

토너 공급장치 {SUPPLYING DEVICE FOR TONER IN ELECTROPHOTOGRAPHIC PROCESSOR}Toner Feeder {SUPPLYING DEVICE FOR TONER IN ELECTROPHOTOGRAPHIC PROCESSOR}

본 고안은 토너 공급장치에 관한 것으로, 특히 현상 카트리지(cartridge)내에서 호퍼의 회전반경밖의 토너를 일종의 진동판을 호퍼의 회전반경 끝단에 설치하여 진동판의 진동에 의해 잔류된 토너를 원활하게 공급하는 토너 공급장치에 관한 것이다.The present invention relates to a toner supply apparatus. In particular, a toner outside the hopper rotation radius in a developing cartridge is provided with a kind of diaphragm at the end of the rotator radius of the hopper to smoothly supply the toner remaining by vibration of the diaphragm. It relates to a supply device.

일반적으로, 현상 카트리지에 있어서 토너를 공급 또는 이송하는 장치는 일정한 회전반경을 가진 호퍼내의 교반기에 의해 공급되는데 대개는 시스템(system)의 공간적인 제약등의 이유로 호퍼의 회전반경보다 큰 토너통의 구조를 가진다. 즉, 회전반경밖의 토너가 자유낙하에 의해 호퍼내로 보급이 되도록 유도하는 구조의 토너 공급장치가 대부분이다. 따라서, 호퍼 회전반경밖의 토너는 자유낙하에 의해 호퍼 회전반경내로 보급이 유도되어지나 현상 카트리지의 구조에서 토너 입사각이 완만한 경우 또는 토너의 물성자체가 흐림이 안좋은 경우 예를들면 비자성 토너등은 토너 공급이 안되는 문제가 발생한다. 또한 호퍼 회전반경밖의 토너는 토너의 물성상 계속 다져지게 되는데 이 다져진 부분을 긁어 내리는 구조가 부가적으로 필요하게 된다.In general, in the developing cartridge, a device for supplying or conveying toner is supplied by an agitator in a hopper having a constant rotation radius. The structure of the toner container is larger than the rotation radius of the hopper, usually due to space constraints of the system. Has That is, most toner supply apparatuses are constructed so as to induce toner to be supplied out of the rotation radius into the hopper by free fall. Therefore, when toner outside the hopper rotation radius is introduced into the hopper rotation radius by free fall, but the toner incidence angle is slow in the structure of the developing cartridge, or when the physical property of the toner is not cloudy, for example, non-magnetic toner, etc. Problems with toner supply occur. In addition, the toner outside the hopper rotation radius is continuously compacted due to the properties of the toner, which additionally requires a structure to scrape off the compacted portion.

본 고안의 목적은 토너통내에 잔존하는 토너를 물리적으로 긁어 내리는 부재를 부착하여 원가 및 생산성 측면을 고려하여 가장 단순하면서도 기능을 십분 발휘할 수 있는 토너 공급 장치를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a toner supply apparatus capable of exhibiting the simplest and most functional function in consideration of cost and productivity by attaching a member that physically scrapes the toner remaining in the toner container.

본 고안의 다른 목적은 호퍼 회전반경밖의 토너를 일종의 진동판을 이용하여 호퍼 회전반경 끝단에 설치하여 호퍼 회전시 회전력으로 상호 접촉을 통하여 인한 간섭에 의해 토너를 공급하는 토너 공급 장치를 제공함에 있다.Another object of the present invention is to provide a toner supply apparatus for supplying toner by interference caused by mutual contact with rotational force during rotation of the hopper by installing a toner outside the hopper rotation radius using a kind of diaphragm at the end of the hopper rotation radius.

상기한 목적들을 달성하기 위한 본 고안의 기술적 사상에 따르면, 일정 주속으로 회전하면서 토너를 교반시켜 공급롤러로 공급하는 호퍼를 구비한 카트리지내의 토너 공급장치에 있어서, 상기 카트리지의 내측에 일단이 지지되며, 타단은 상기 호퍼의 회전에 의한 간섭을 받기 위하여 호퍼의 회전반경내에 위치하도록 하여, 상기 호퍼의 회전력을 이용하여 상하 및 좌우로 진동하면서 호퍼 회전반경밖의 토너를 보급하는 토너 공급보조부를 구비함을 특징으로 한다.According to the technical idea of the present invention for achieving the above objects, in the toner supply apparatus in a cartridge having a hopper for stirring and supplying the toner to a feed roller while rotating at a constant circumferential speed, one end is supported inside the cartridge. And, the other end is located in the radius of rotation of the hopper to receive interference by the rotation of the hopper, by using the rotational force of the hopper vibrating up and down and left and right while having a toner supply assistant for supplying the toner outside the rotation radius of the hopper. It features.

도 1은 본 고안의 일실시예에 따른 카트리지내의 토너 공급장치를 보여주는 단면도.1 is a cross-sectional view showing a toner supply apparatus in a cartridge according to an embodiment of the present invention.

도 1은 본 발명의 일실시예에 따른 토너 공급 장치를 보이는 단면도이다. 도 1을 참조하면, 현상 카트리지 10내에 토너 교반을 위한 호퍼 30과, 현상 카트리지에 진동판으로 형성되어 부착되며 일끝단이 호퍼와 소정 부분 맞닿게 형성되는 토너 공급보조부 20과, 상기 호퍼 30을 통하여 공급되는 토너를 내부로 이송하기 위한 공급롤러 40으로 구성된다. 여기서 토너 공급보조부 20은 진동을 가지는 필름(film)으로 형성된다. 따라서, 호퍼 30의 회전시 호퍼 30이 현상 카트리지 10 측벽에 부착된 토너 공급보조부 20 예를들면 진동판의 가장자리를 치게 되는데 이때의 충격에 의한 힘으로 상기 진동판은 일정한 장력(tention)을 가지게 된다. 이에 따라 진동판이 상하로 진동되면서 근방에 쌓인 토너를 흩날리면서 호퍼 반경내로 토너를 공급한다. 따라서 호퍼 반경내로 공급된 토너는 호퍼 30에 의해 공급롤러 40으로 공급되게 된다.1 is a cross-sectional view showing a toner supply apparatus according to an embodiment of the present invention. Referring to FIG. 1, a hopper 30 for toner agitation in a developing cartridge 10, a toner supply auxiliary unit 20 formed as a diaphragm attached to a developing cartridge, and one end of which is in contact with a predetermined portion of the hopper, is supplied through the hopper 30. It consists of a feed roller 40 for conveying the toner to be inside. The toner supply auxiliary unit 20 is formed of a film having a vibration. Accordingly, when the hopper 30 is rotated, the hopper 30 hits the edge of the toner supply auxiliary part 20 attached to the development cartridge 10 sidewall, for example, the diaphragm, and the diaphragm has a constant tension due to the force caused by the impact. As a result, the diaphragm vibrates up and down, while scattering the toner accumulated in the vicinity, and supplying the toner within the radius of the hopper. Therefore, the toner supplied into the hopper radius is supplied to the supply roller 40 by the hopper 30.

상기한 본 고안의 토너 공급장치에 따르면, 현상 카트리지내의 토너잔량을 최소화하여 최소의 토너주입으로 현상 카트리지의 보증수면을 달성함으로써 원가 절감 및 환경 개선을 가져오는 효과가 있다.According to the toner supply apparatus of the present invention, by minimizing the amount of toner remaining in the developing cartridge to achieve a guaranteed sleep of the developing cartridge with a minimum amount of toner injection, there is an effect of reducing costs and improving the environment.
