본 발명은 오일 균등 분사장치에 관한 것으로, 보다 상세하게는 스트립 표면에 녹방지를 위해 오일을 도포할 때에 압축에어를 이용하여 균등하게 분사토록 하여 도포불량을 없애 도포품위를 높일 수 있도록 한 오일 균등 분사장치에 관한 것이다.The present invention relates to an oil equalizing device, and more particularly, to uniformly spray oil using a compressed air when applying oil to prevent rust on the surface of the strip to remove coating defects and to improve the coating quality. It relates to an injection device.

일반적으로, 산업용으로 사용되는 모든 강판은 녹 방지를 위해 스트립 표면에 오일을 도포하여 유막을 형성하고 있다.In general, all steel sheets used for industrial use are coated with oil on the strip surface to prevent rust, thereby forming an oil film.

이러한 유막은 내식성을 강화시켜 외부환경으로부터 스트립을 보호하고, 추후 프레스 등 별도의 가공시 윤활성을 향상시켜 강판의 균열을 방지하게 된다.The oil film enhances the corrosion resistance to protect the strip from the external environment, and to improve the lubricity during further processing such as press to prevent cracking of the steel sheet.

이와 같은 오일 도포를 위해 종래에는 도 1의 예시와 같은 오일 도포장치가 사용되었다.In order to apply such oil, conventionally, an oil coating device such as the example of FIG. 1 is used.

예컨대, 도 1에서와 같이, 냉연 스트립(S)이 통과되는 오일도포롤(1)의 상부에 오일공급라인(2)이 배관되고, 상기 오일공급라인(2)에는 다수개의 노즐(3)이 설치되어 이를 통해 공급된 오일(4)이 오일도포롤(1)의 표면에 묻게 되고, 오일도포롤(1)의 회전에 의해 표면에 묻어 있던 오일(4)이 냉연 스트립(S) 표면으로 전도되어 도포되도록 동작하였다.For example, as shown in FIG. 1, an oil supply line 2 is piped on an oil coating roll 1 through which a cold rolled strip S passes, and a plurality of nozzles 3 are provided on the oil supply line 2. The oil (4) installed through this is buried on the surface of the oil coating roll (1), the oil (4) buried on the surface by the rotation of the oil coating roll (1) is conducted to the cold rolled strip (S) surface. To operate.

여기에서, 설명의 편의상 스트립(S) 상부에 배치된 오일도포롤을 중심으로 설명하였으나 하부에 배치된 오일도포롤도 마찬가지이다.Here, for the sake of convenience of explanation, the description will be made based on the oil coating roll disposed above the strip S, but the same also applies to the oil coating roll disposed below.

그런데, 공급된 오일(4)은 노즐(3)이 일정개소에 고정된 상태로 설치되어 있기 때문에 항상 동일지점의 오일도포롤(1) 표면에 떨어지게 되고, 이로 인해 오일도포롤(1)이 해당 위치에는 오일찌꺼기가 누적되게 되며, 이 상태에서 지속적으로 오일 도포를 행하게 되면 예시된 바와 같은 줄무늬 결함(5)이 유발되게 된다.However, since the supplied oil 4 is installed in a state where the nozzle 3 is fixed at a predetermined position, the oil 4 always falls on the surface of the oil coating roll 1 at the same point, and thus the oil coating roll 1 is applied. Oil residues accumulate in the position, and continuous application of oil in this state causes streaked defects 5 as illustrated.

결국, 이러한 줄무늬 결함(5)은 불균일한 오일 도포상태를 유발하게 되고, 이는 스트립(S) 표면의 내식성, 윤활성에 커다란 영향을 미치게 된다.As a result, such stripe defects 5 cause an uneven oil coating state, which greatly affects the corrosion resistance and lubricity of the surface of the strip S.

뿐만 아니라, 다수개의 노즐(3)중 어느 하나가 막히게 되면 어느 노즐(3)이 막혔는지 쉽게 파악할 수 없을 뿐더러 그로 인한 오일 도포 불균일은 연속적으로 발생하게 되어 그 파급효과가 지대하게 된다.In addition, when any one of the plurality of nozzles (3) is clogged, it is not easy to determine which nozzle (3) is clogged, and the oil coating non-uniformity caused by it occurs continuously, the ripple effect is large.

본 발명은 상술한 바와 같은 종래 기술상의 한계점을 감안하여 이를 해결하고자 창출한 것으로, 오일도포롤의 표면에 좌우 교대되게 이동되면서 압축분사 방식의 오일 공급을 통해 오일찌꺼기의 누적을 없애고 균등한 오일공급이 가능토록 하여 보다 균일한 오일 도포를 가능하게 함으로써 오일의 도포품위를 급신장시킬 수 있도록 한 오일 균등 분사장치를 제공함에 그 주된 목적이 있다.The present invention was created in view of the limitations of the prior art as described above, while moving left and right alternately on the surface of the oil coating roll to eliminate the accumulation of oil residues through the oil supply of the compression injection method and to supply the oil evenly The main object of the present invention is to provide an even oil spray device which enables a more uniform oil coating so as to make it possible to rapidly expand an oil coating product.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

오일도포롤(1)로 오일을 공급하기 위해 구동모터(140)를 구동시키면 그와 연결된 스크류샤프트(110)가 회전되게 된다.When the driving motor 140 is driven to supply oil to the oil coating roll 1, the screw shaft 110 connected thereto is rotated.

이때, 상기 스크류샤프트(110)의 단부에는 구동베벨기어(112)와, 종동베벨기어(114)가 종동축(116)에 의해 한쌍의 스크류샤프트가 모두 연결되어 회전구동되게 된다.At this time, the end of the screw shaft 110, the driving bevel gear 112, and the driven bevel gear 114 is a pair of screw shafts are all connected by the driven shaft 116 is rotated to drive.

따라서, 한쌍의 분사노즐몸체(300)는 서로 반대방향으로 동시에 이동가능하게 된다.Thus, the pair of injection nozzle bodies 300 can be moved simultaneously in opposite directions.

즉, 스크류샤프트(110)에 맞물린 스크류결합구(210)에 의해 분사노즐몸체(300)는 이동되게 되고, 동시에 피니언(230)은 래크(130)와 맞물리 상태로 회전되면서 2개의 분사노즐(310)도 교대로 반복회전되게 된다.That is, the injection nozzle body 300 is moved by the screw coupling member 210 engaged with the screw shaft 110, and at the same time, the pinion 230 is rotated in engagement with the rack 130 and the two injection nozzles ( 310 is also repeatedly rotated alternately.

동시에, 오일공급관(420)을 통해 공급된 오일은 분사노즐(310)을 거쳐 오일도포롤(1)의 표면에 분사되게 된다.At the same time, the oil supplied through the oil supply pipe 420 is sprayed onto the surface of the oil coating roll 1 via the spray nozzle 310.

이때, 상기 오일은 압축공기에 의해 고압분사되게 되므로 노즐 막힘현상을 최소화하면서 균일한 공급이 가능하게 된다.At this time, since the oil is high-pressure sprayed by the compressed air it is possible to uniformly supply the nozzle while minimizing nozzle clogging.

이렇게 하여, 분사노즐몸체(300)가 오일도포롤(1)의 에지부까지 이동되게 되면, 바퀴(550)가 방향전환부재(170)를 타고 올라가게 되고, 그 과정에서 터치편(506)이 리미트스위치(180)를 터치하게 된다.In this way, when the injection nozzle body 300 is moved to the edge of the oil coating roll (1), the wheel 550 rides up the turning member 170, the touch piece 506 in the process The limit switch 180 is touched.

리미트스위치(180)가 터치되면 동시에 구동모터(140)는 역회전되게 되고, 이에 따라 분사노즐몸체(300)는 진행방향 반대로 진행을 계속하면서 오일을 상술한 바와 같은 방법으로 똑같이 공급하게 된다.At the same time when the limit switch 180 is touched, the driving motor 140 is reversely rotated. Accordingly, the injection nozzle body 300 supplies oil in the same manner as described above while continuing to move in the opposite direction of the traveling direction.

이 과정에서, 상기 바퀴(550)가 방향전환부재(170)를 타고 올라가면서 천공핀(500)은 전진하여 분사노즐(310)의 내부 공간을 뚫게 된다.In this process, as the wheel 550 climbs up the turning member 170, the drilling pin 500 moves forward to pierce the internal space of the injection nozzle 310.

이때, 상기 방향전환부재(170)가 설치된 부분과 대응되는 위치의 래크(130)상에는 기어가 형성되어 있지 않아 상기 천공핀(500)의 상승시에는 피니언(230)이 회전되지 않도록 함이 바람직하다.At this time, since the gear is not formed on the rack 130 at a position corresponding to the portion where the direction switching member 170 is installed, the pinion 230 is preferably not rotated when the punching pin 500 is raised.

이와 같은 과정을 반복하여 수행함으로써 오일 도포를 위한 오일도포롤(1)로의 오일 공급을 균일하고 정확하며 노즐 막힘없이 수행할 수 있게 된다.By repeating such a process, the oil supply to the oil coating roll 1 for oil application can be performed uniformly, accurately and without clogging the nozzle.

이상에서 상세히 설명한 바와 같이, 본 발명은 오일도포롤 표면으로 공급되는 오일이 동일지점에 연속하여 묻혀지는 것이 아니라 이동되면서 묻혀지는 지점이 가변되도록 하여 오일찌꺼기의 누적을 방지하고, 그로 인해 오일 도포품위를 향상시킴은 물론 압축공기를 사용하여 오일을 분사 공급하기 때문에 노즐 막힘이 없어 그 사용수명도 연장하는 효과를 제공한다.As described in detail above, the present invention is to prevent the accumulation of oil residues by varying the point to be buried while moving the oil supplied to the surface of the oil coating roll is not buried continuously at the same point, thereby the oil coating product In addition to improving the flow rate, the air is sprayed and supplied using compressed air, thereby providing the effect of prolonging the service life since there is no nozzle clogging.
