Abstract

본 고안은 합성섬유 방사 시 필라멘트에 오일을 공급하는 장치인 오일급유장치에 관한 것으로서, 보다 상세하게는 필라멘트와의 접촉을 피하도록 하는 동시에 필라멘트의 주행에 의한 압력구배를 이용하여 필라멘트에 오일을 공급하는 압력구배를 이용한 비접촉 오일급유장치에 관한 것이다.The present invention relates to an oil lubrication device that supplies oil to the filament when spun synthetic fibers, and more specifically to avoid contact with the filament and at the same time to supply the oil to the filament by using a pressure gradient due to the filament running It relates to a non-contact oil lubrication device using a pressure gradient.

이를 위하여 삽입공(101)의 내측벽에 오일급유구(103)를 삽입공 내경의 접선방향으로 배치하고 삽입공의 중심은 필라멘트가 고속으로 주행시켜 삽입공 내부에 압력구배를 형성한다. 즉, 삽입공(101)의 중심에는 필라멘트의 고속주행으로 인하여 압력이 강하하게 된다.To this end, the oil lubrication opening 103 is disposed on the inner wall of the insertion hole 101 in the tangential direction of the insertion hole inner diameter, and the center of the insertion hole runs at a high speed to form a pressure gradient inside the insertion hole. In other words, the pressure of the insertion hole 101 is lowered due to the high-speed running of the filament.

이러한 압력구배에 의해 오일급유구(103)에 있던 오일을 필라멘트로 공급하게 되므로 필라멘트가 접촉에 의한 마찰저항을 최소화할 수 있으며, 접촉에 의한 다른 오일급유방식보다 더 넓은 면에 오일을 공급할 수 있다.Since the oil in the oil supply port 103 is supplied to the filament by such a pressure gradient, the filament can minimize the frictional resistance due to contact, and the oil can be supplied to a wider surface than other oil supply methods by contact. .

본 고안은 합성섬유 방사 시 필라멘트에 오일을 공급하는 장치인 오일급유장치에 관한 것으로서, 보다 상세하게는 필라멘트의 접촉을 피하도록 하는 동시에 필라멘트의 주행에 의한 압력구배를 이용하여 필라멘트에 오일을 공급하는 압력구배를 이용한 비접촉 오일급유장치에 관한 것이다.The present invention relates to an oil lubrication device that supplies oil to the filament when spun synthetic fibers, and more specifically to avoid the contact of the filament and at the same time to supply the oil to the filament using a pressure gradient due to the filament running It relates to a non-contact oil lubrication device using a pressure gradient.

일반적으로 합성섬유의 섬유형성(纖維形成) 공정을 방사(紡絲)라 하는데, 이러한 섬유는 물질의 크기가 아주 미세하므로 방사공정에서는 섬유의 절단으로 인한 생산성의 저하가 가장 큰 문제점이라 할 수 있다. 이러한 문제점을 해소하는 방법들이 다양하게 연구되고 있으며, 그 중의 하나로 필라멘트에 오일을 도포함으로써 필라멘트의 표면마찰을 감소시키고 제전성을 부여하여 권취공정에서의 사손상을 감소시키고, 후공정에서의 해사성을 향상시키는 데, 이와 연관된 분야로서 오일(방사유제)의 개발, 오일 급유장치의 설계, 오일확산장치의 설계 등이 있으며, 본 고안은 이 중에서 오일 급유장치의 설계에 관한 것이다.In general, the fiber forming process of synthetic fibers is called spinning, and since these fibers have a very fine material size, the biggest problem is the decrease in productivity due to fiber cutting in the spinning process. . Various methods have been studied to solve this problem, and one of them is applying oil to the filament to reduce the surface friction of the filament and impart antistaticity, thereby reducing the damage in the winding process, and the maritime properties in the post process. In this regard, related fields include the development of oil (radio oil), the design of the oil lubrication device, the design of the oil diffusion device, and the present invention relates to the design of the oil lubrication device.

종래 사용되는 오일 급유장치는 도 1에서 보는 바와 같이 필라멘트가 a부분과 접촉하여 통과함으로써 오일이 공급되는데 오일의 균일부착이 가능하다는 장점이 있으나, 필라멘트가 접촉되는 표면에서 마찰저항이 발생하고 필라멘트에 장력이부과되므로 필라멘트의 가닥수를 늘이거나 권취속도를 높이는 데 제한을 받게 되는 문제점이 있다.The oil lubrication apparatus used in the prior art has the advantage that the oil is supplied by passing the filament in contact with the a part as shown in FIG. 1, but the oil can be uniformly attached, but friction resistance occurs at the surface where the filament is in contact with the filament. Since the tension is applied, there is a problem in that the number of strands of the filament is limited or the winding speed is increased.

도 2는 또 다른 종래 오일 급유장치를 나타내는 사시도로서, 필라멘트가 이송홈을 통해 이송되고, 이송되는 원사가 오일구멍(b)을 통해 공급되는 오일에 의해 오일링되도록 되어 있다. 이 경우 오일급유장치에 의해 필라멘트에 부과되는 장력은 적으나 필라멘트와의 접촉을 통해 오일을 공급하게 되므로 필라멘트의 가닥수를 늘이거나 권취속도를 높이는 데 여전히 제한을 받게 된다.Figure 2 is a perspective view showing another conventional oil lubrication device, the filament is conveyed through the conveying groove, the yarn to be conveyed is to be oiled by the oil supplied through the oil hole (b). In this case, the tension imposed on the filament by the oil lubrication device is small, but the oil is supplied through contact with the filament, it is still limited to increase the number of strands of the filament or to increase the winding speed.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위해, 필라멘트의 접촉을 피하도록 하는 동시에 필라멘트의 주행에 의한 압력구배를 이용하여 필라멘트에 오일을 공급할수 있는 압력구배를 이용한 비접촉 오일급유장치를 제공하는데 그 목적이 있다.The present invention provides a non-contact oil lubrication device using a pressure gradient that can supply oil to the filament using a pressure gradient caused by the filament while avoiding the contact of the filament to solve the conventional problems as described above. The purpose is.

본 고안에 따른 압력구배를 이용한 비접촉 오일급유장치(100)는 전술한 목적을 달성하기 위하여 필라멘트가 접촉되지 않는 크기의 삽입공(101)이 형성되며, 상기 삽입공의 내측벽에는 삽입공 내경의 접선방향으로 오일급유구(103)가 형성되는 것을 그 기술적 구성상의 기본 특징으로 한다.The non-contact oil lubrication device 100 using the pressure gradient according to the present invention is formed in the insertion hole 101 of the size that the filament is not in contact to achieve the above object, the inner wall of the insertion hole of the insertion hole inner diameter The oil lubrication opening 103 is formed in the tangential direction as a basic feature of the technical configuration.

이하 첨부된 도면을 참조하여 본 고안의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 고안에 따른 압력구배를 이용한 비접촉 오일급유장치(100)는 세라믹으로 가공되는 것으로서, 도 3과 도 4를 참조하여 살펴보면 필라멘트가 주행할 수 있는 원형의 삽입공(101)을 필라멘트가 접촉되지 않는 정도의 크기로 형성하고, 삽입공의 내측벽에는 원사유입구(102)와 오일급유구(103)가 형성된다. 오일급유구(103)는 삽입공 내경의 접선방향으로 삽입공(101)과 연통되며, 오일의 원활한 유동을 위하여 점차 넓어지는 형상으로 오일급유공(104)과 연통된다.The non-contact oil lubrication device 100 using the pressure gradient according to the present invention is processed into a ceramic, the filament is not in contact with the circular insertion hole 101 that can be seen with reference to Figures 3 and 4 It is formed to a size of a degree, and the yarn inlet 102 and the oil supply port 103 is formed on the inner wall of the insertion hole. The oil lubrication opening 103 communicates with the insertion hole 101 in the tangential direction of the insertion hole inner diameter, and communicates with the oil lubrication hole 104 in a shape that gradually widens for a smooth flow of oil.

이와 같이 구성되는 본 고안에 따른 압력구배를 이용한 비접촉 오일급유장치(100)는 필라멘트가 삽입공(101)의 중심을 고속으로 주행함으로써 삽입공 내부에 압력구배를 형성하게 된다. 즉, 삽입공(101)의 중심에는 필라멘트의 고속주행으로 인하여 압력이 강하하게 되며, 이러한 압력구배에 의해 주행하는 필라멘트는 삽입공(101)의 중심에 위치하는 상태를 유지하게 되고 오일급유구(103)에 있던 오일은 삽입공 내부로 분무된다. 여기서, 보다 효과적인 압력구배를 위하여 오일급유공(104)에서 오일급유구(103)에 이르는 경로에는 도 3에서 보는 바와 같이 외부공기와 접촉되지 않도록 폐쇄하고 오로지 삽입공과 연통되도록 형성한다.The non-contact oil lubrication device 100 using the pressure gradient according to the present invention configured as described above forms a pressure gradient inside the insertion hole by running the filament at high speed through the center of the insertion hole 101. That is, the pressure of the filament is lowered in the center of the insertion hole 101 due to the high-speed running of the filament, the filament running by this pressure gradient is maintained in the state of the center of the insertion hole 101 and the oil lubrication hole ( The oil in 103 is sprayed into the insertion hole. Here, the path from the oil lubrication hole 104 to the oil lubrication hole 103 is closed so as not to contact external air as shown in FIG. 3 and formed only in communication with the insertion hole for a more effective pressure gradient.

또한, 오일급유구(103)의 방향이 삽입공의 접선방향이므로 오일급유구(103)에서 분무되는 오일은 필라멘트의 고속주행의 영향을 받아 나선형태의 유동으로 필라멘트에 공급된다. 따라서 필라멘트와 삽입공 내측벽과의 접촉을 방지하면서 접촉에 의한 오일급유방식보다 더 넓은 면에 오일을 공급할 수 있다.In addition, since the direction of the oil supply port 103 is the tangential direction of the insertion hole, the oil sprayed from the oil supply port 103 is supplied to the filament in a spiral flow under the influence of the high-speed running of the filament. Therefore, it is possible to supply oil to a wider surface than the oil lubrication method by contact while preventing contact between the filament and the inner wall of the insertion hole.

도 5를 참조하여 살펴본 오일급유장치 고정케이스(200)는 상기 오일급유장치(100)가 끼워 고정될 수 있도록 오일급유장치 고정홈(201)이 형성되고 볼트나 나사 등으로 고정된다.The oil lubrication device fixing case 200 described with reference to FIG. 5 has an oil lubrication device fixing groove 201 formed therein so that the oil lubrication device 100 can be fitted and fixed, and is fixed with a bolt or a screw.

이상에서 살펴본 바와 같이, 본 고안은 필라멘트가 주행하는 삽입공(101)내에 접선방향으로 오일급유구(103)를 형성하여 삽입공(101)내를 주행하는 필라멘트와의 접촉을 방지하면서 넓은 필라멘트면에 오일을 급유할 수 있다. 따라서, 필라멘트의 가닥수를 많게 형성하거나 고속방사의 경우 필라멘트 절단의 문제를 해소하여 생산성을 높일수 있는 효과가 있다.As discussed above, the present invention forms an oil lubrication port 103 in a tangential direction in the insertion hole 101 through which the filament travels, thereby preventing contact with the filament traveling in the insertion hole 101 while maintaining a wide filament surface. You can refuel the oil. Therefore, it is possible to increase the productivity by forming a large number of strands of filament or solving the problem of filament cutting in the case of high-speed spinning.
