Description

압축공기를 이용한 실링장치{SEALING APPARATUS USING COMPRESSED AIR}Sealing device using compressed air {SEALING APPARATUS USING COMPRESSED AIR}

본 발명은 압축공기를 이용한 실링장치에 관한 것으로서, 보다 상세하게는 유지비용이 적게 들고, 수리가 용이하도록 개선된 압축공기를 이용한 실링장치에관한 것이다.The present invention relates to a sealing apparatus using compressed air, and more particularly, to a sealing apparatus using compressed air, which is improved in order to reduce maintenance costs and to facilitate repair.

도 1에 도시된 바와 같이, 전동모터(11)를 이용한 스월 실링(swirl sealing)장치는, 전동모터(11)가 자장에 의해 베어링(12)을 이용하여 전동모터(11) 안쪽의 커플러(coupler)(13)를 회전시키면 튜브(tube)(14)가 베어링(15)에 접촉되어 커플러(13) 내경 편심을 따라 선회함으로써 팁(tip)(16) 중심축이 이동되어 도포되는 실러(sealer)가 회전하는 방식이다.As shown in FIG. 1, in the swirl sealing apparatus using the electric motor 11, the coupler inside the electric motor 11 uses the bearing 12 by the magnetic field of the electric motor 11. Rotating the (13) causes the tube (14) to contact the bearing (15) and pivot along the inner diameter eccentric of the coupler (13) to move and apply the seal (center) of the tip (16) central axis. Is the way to rotate.

그런데, 상기와 같이 서보모터를 이용하는 종래의 스월 실링장치는, 고가이고, 회전시 발열에 의한 소손방지를 위해 브러시가 없고, 최대 회전수가 20,000rpm인 특수모터를 사용함으로써 고장시 보수가 어려워 교체해야 하므로 유지비용이 과다하게 소요되는 문제점이 있다.However, the conventional swirl sealing apparatus using the servo motor as described above is expensive, and it is difficult to repair it by using a special motor with no brush and a maximum rotational speed of 20,000 rpm to prevent burnout by heat generation during rotation. Therefore, there is a problem that takes too much maintenance cost.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 유지비용이 적게 들고, 수리가 용이하도록 한 압축공기를 이용한 실링장치를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a sealing device using compressed air which is low in maintenance cost and easy to repair.
