본 고안은 브라운관 펀넬의 내장흑연 건조장치의 개량에 관한 것이다.The present invention relates to an improvement of the built-in graphite drying apparatus of CRT.

제 1 도에 도시된 바와 같이 펀넬(funnel : F)의 후면에 도포되는 내장흑연막(C)은 아노드(A)에서 인가되는 전압을 네크(N)에 수납되는 전자총(도시안됨)과 함께 콘덴서(capacitor)의 기능을 하게 된다.As shown in FIG. 1, the built-in graphite C coated on the rear surface of the funnel F has an electron gun (not shown) that receives the voltage applied from the anode A in the neck N. It will function as a capacitor.

이러한 내장흑연막을 형성하는 방법은 흑연을 적절한 바인더등과 혼합하여 된 흑연도료를 소요부위에 도포하여 건조시키는 방법인데, 이와 같은 내장흑연을 건조시키는 장치의 종래의 일례를 제 2 도에 보였다.A method of forming such a built-in graphite film is a method of applying a graphite paint obtained by mixing graphite with an appropriate binder and the like to a required portion and drying it. An example of a conventional apparatus for drying the built-in graphite is shown in FIG.

이것은 복수의 가열수단, 예를 들어 적외선등(燈)(3)이 그 측벽에 배열된 건조로(1')의 내부로 컨베이어(5)에 의해 행거(6)에 거치된 펀넬(F)을 통과시킴으로써 건조를 행하였다.This allows the funnel F mounted on the hanger 6 by the conveyor 5 to the interior of the drying furnace 1 ′ in which a plurality of heating means, for example infrared light 3, is arranged on its side wall. It dried by letting it pass.

여기서 흑연이 도포된 펀넬(F)은 도시된 바와 같이 그 개방부측을 상방으로 하여 행거(6)에 거치되는데, 이와 같은 방식은 도포된 흑연으로부터 발생되는 증기나 유기 용제등의 발산이 용이하므로 건조효율이 증진되는 잇점이 있으나, 컨베이어(5)와 건조로(1')간의 개구부(4)등 상부로부터 먼지나 이물질이 떨어져 내장흑연막에 부착되는 문제점이 있었다.Here, the funnel F coated with graphite is mounted on the hanger 6 with its open side upward, as shown in the figure. In this manner, it is easy to dissipate vapor or organic solvent generated from the coated graphite and dry it. Although there is an advantage that the efficiency is improved, there is a problem that dust or foreign matter is dropped from the upper portion such as the opening 4 between the conveyor 5 and the drying furnace 1 'and attached to the embedded graphite film.

이와 같은 내장흑연의 오염은 브라운관의 완성후 부분적 소작(燒灼)등의 문제를 야기하므로 이물질이 부착된 펀넬은 불량으로 처리할 수 밖에 없었다.Such contamination of the built-in graphite causes problems such as partial cauterization after completion of the CRT, so the funnel with foreign matters was inevitably treated as defective.

이와 같은 문제를 피하기 위해 네크부를 상방으로 하여 펀넬(F)을 거치시키는 방안도 고려될 수 있으나, 이 경우 건조효율이 낮을 뿐 아니라 도포된 흑연에서 발생되는 증기 또는 유기용제가 네크(N)의 좁은 관로로 집중되면서 그 내경부에 물방울을 형성하고, 이것이 흘러 내리면서 흑연의 흡착력을 저하시켜 이를 부분적으로 탈락시킴으로써 불량을 야기하는 다른 문제점을 유발하였다.In order to avoid such a problem, a method of mounting the funnel F with the neck upward may be considered, but in this case, the drying efficiency is low and the vapor or organic solvent generated from the coated graphite is narrow in the neck (N). Concentrating in the pipeline, water droplets were formed in the inner diameter, and as it flowed down, the adsorption force of the graphite was lowered, thereby partially dropping it, causing another problem causing the defect.

본 고안은 상술한 종래 기술들의 문제점을 해결하고자 창출된 것으로, 건조효율이 높으며 이물질의 오염이나 흑연의 부분적 탈락이 없는 브라운관 펀넬의 내장흑연 건조장치를 제공하는 것을 그 목적으로 한다.The present invention was created to solve the problems of the above-described prior arts, and has an object of providing a built-in graphite drying apparatus of a CRT which has a high drying efficiency and no contamination of foreign substances or partial dropout of graphite.

이와 같은 목적을 달성하기 위해 본 고안에 따른 건조장치는 각각 흑연이 도포된 하나 또는 복수의 펀넬을 거치하는 행거와, 그 내부에 복수의 가열수단이 설치된 건조로와, 상기 행거를 상기 건조로의 내부로 이송시키는 컨베이어를 구비하여 된 브라운관 펀넬의 내장흑연 건조장치에 있어서, 상기 펀넬이 그 네크측이 상방을 향하도록 상기 행거에 거치되며, 상기 건조로의 바닥면에는 상기 펀넬의 내면에 대해 기류를 제공하는 기류공급수단이 설치되어 된 것을 특징으로 한다.In order to achieve the above object, a drying apparatus according to the present invention includes a hanger for mounting one or a plurality of funnels each coated with graphite, a drying furnace provided with a plurality of heating means therein, and the hanger into the drying furnace. In the built-in graphite drying apparatus of the CRT funnel provided with a conveyor for conveying, the funnel is mounted to the hanger so that the neck side is upward, the bottom surface of the drying furnace to provide air flow to the inner surface of the funnel It is characterized in that the air flow supply means is installed.

본 고안의 다른 특징이나 이점들은 다음의 첨부된 도면을 참조로 한 바람직한 실시예의 설명에서 더욱 명확해질 것이다.Other features or advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

제 3 도 및 제 4 도에 도시된 본 고안에 따른 건조장치는 펀넬(F)을 지지하는 행거(6)가 매달린 컨베이어(5)가 설치되고, 천정(1a) 및 내벽(1b)에 가열수단으로서 복수의 적외선등(3)이 설치된 건조로(1)가 그 주위를 감싸고 있으며, 건조로(1)의 바닥면(7)에는 기류공급수단으로서 복수의 노즐(8)군(群)이 열설(列設)된 분배관(9)이 설치된다. 이 분배관(9)은 도시되지 않은 고압가스공급관에 연결되어 있으며, 부호 10은 이 분배관(9)을 건조로(1)의바닥면(7)에 지지하는 브라켓이다.The drying apparatus according to the present invention shown in FIGS. 3 and 4 is provided with a conveyor 5 on which a hanger 6 supporting the funnel F is mounted, and heating means on the ceiling 1a and the inner wall 1b. The drying furnace 1 provided with a plurality of infrared lamps 3 surrounds the surroundings, and a plurality of nozzles 8 groups are installed on the bottom surface 7 of the drying furnace 1 as an airflow supply means. (Iii) a distribution pipe 9 is provided. This distribution pipe 9 is connected to a high-pressure gas supply pipe not shown, and reference numeral 10 denotes a bracket for supporting the distribution pipe 9 on the bottom surface 7 of the drying furnace 1.

여기서 컨베이어(5)는 펀넬의 연속생산 라인의 일부인 것이 바람직하며, 건조로(1)의 천정(1a)은 기류의 원활한 배출을 위해 그 중심을 향해 상향으로 경사되도록 설치되는 것이 바람직하다.The conveyor 5 is preferably part of the continuous production line of the funnel, the ceiling (1a) of the drying furnace 1 is preferably installed to be inclined upward toward the center for the smooth discharge of the air flow.

여기서 행거(6)는 하나 또는 복수의 펀넬(F)을 그 네크(N)측을 상방으로 하여 거치할 수 있도록 구성되는 것이 바람직하며, 분배관(9)에 열설된 노즐(8)은 수직 상방으로 행거(6)에 거치된 펀넬(F)의 내면을 향해 적절한 압력의 기류, 바람직하기로는 건조공기를 분사해 주도록 구성되는 것이 바람직하다.The hanger 6 is preferably configured to mount one or a plurality of funnels (F) to the neck (N) side upward, the nozzle (8) opened in the distribution pipe (9) is vertically upward Therefore, it is preferable that the air flow at an appropriate pressure, preferably dry air, is sprayed toward the inner surface of the funnel F mounted on the hanger 6.

이와 같이 구성된 본 고안에 따른 건조장치의 작동은 다음과 같다.Operation of the drying apparatus according to the present invention configured as described above is as follows.

먼저 흑연이 도포된 펀넬(F)이 그 네크(N)측을 상방으로 하여 행거(6)에 거치된 채 컨베이어(5)에 의해 건조로(1)의 내부로 진입하게 된다.First, the funnel F coated with graphite enters the interior of the drying furnace 1 by the conveyor 5 while being mounted on the hanger 6 with its neck N side upward.

이때 건조로(1)의 내부에 설치된 적외선등(3)의 가열에 의해 도포된 흑연에 포함되어 있던 증기와 유기 용매등이 발생되면 이 증기등은 노즐(8)군에서 분사되는 기류에 의해 네크(N)를 통과하여 상방으로 배출된다.At this time, if the vapor and organic solvent contained in the graphite applied by the heating of the infrared lamp 3 installed in the drying furnace 1 are generated, the vapor lamp is necked by the airflow injected from the nozzle 8 group. It passes through (N) and is discharged upwards.

이에 따라 상술한 증기등이 발생즉시 배출되므로 물방울의 형성이나 이에 따른 문제점이 발생되지 않을 뿐아니라, 공급되는 기류에 의해 건조가 촉진되어 건조시간이 단축되고 완전한 건조가 이뤄지게 된다.Accordingly, the above-described steam is discharged immediately, so that the formation of water droplets and the problems thereof are not generated, and the drying is accelerated by the supplied airflow, thereby shortening the drying time and achieving complete drying.

이와 같이 본 고안에 따른 건조장치는 이물의 부착이 없도록 펀넬을 패널측을 상방으로 하여 건조하면서도 이에 따른 문제점을 제거함으로서 신속하고 완전한 건조를 행하여, 건조된 펀넬의 품질을 향상시키고 불량률을 감소시키는 장점이 있다.As described above, the drying apparatus according to the present invention performs the fast and complete drying by removing the problem while drying the funnel upwards to the panel side so that there is no foreign matter, thereby improving the quality of the dried funnel and reducing the defective rate. There is this.
