Description

종이 빨대의 제조 시스템에 구비된 기름도포부{oil coating section of paper straw manufacturing system}Oil coating section of paper straw manufacturing system

본 발명은, 종이 빨대의 제조 시스템에 구비된 기름도포부에 관한 것으로서, 보다 상세하게는 히팅부와 맨드릴 사이에 배치되어 히팅부에서 맨드릴로 이송되는 상 종이띠의 윗면에 기름을 도포하는 기름도포부에 관한 것이다.The present invention relates to an oil application unit provided in a system for manufacturing paper straws, and more particularly, an oil for applying oil to the upper surface of the paper strip that is disposed between the heating unit and the mandrel and transferred from the heating unit to the mandrel. It's about aspirations.

종래의 빨대는 플라스틱 소재로 형성되는 경우가 많았다. 플라스틱 소재의 빨대는 가공이 용이하고 제조 비용이 낮으며, 무게가 가볍고, 사용시 음료에 다른 성분이 섞일 문제가 발생하지 않는다는 장점이 있다. 하지만 물질 특성상 버려진 이후 분해되는데 상당히 오랜 시간이 소요되며, 인체에도 유해하므로 이를 대체해야 한다는 목소리가 커지고 있다.Conventional straws were often formed of a plastic material. Plastic straws are easy to process, low in manufacturing cost, light in weight, and have advantages in that there is no problem of mixing other ingredients into beverages when used. However, due to the nature of the material, it takes a long time to decompose after being discarded, and it is also harmful to the human body, so there are growing calls to replace it.

이러한 요구에 대한 해결책으로 제조한 빨대를 재사용하는 방법, 또는 빨대의 성분 자체를 친환경적인 소재로 대체하는 방안에 대해 지속적으로 개발이 이루어지고 있다. 예를 들어 재사용 가능한 플라스틱 또는 금속으로 제조된 빨대 등이 제안된다. 하지만 빨대는 업소용으로 사용되는 경우가 많으며, 이 경우 빨대를 재사용하여 사용하는 것은 위생이나 각 업소의 인프라 구조상 한계가 있다.As a solution to these needs, a method of reusing the manufactured straw or a method of replacing the straw itself with an eco-friendly material is continuously being developed. For example, straws made of reusable plastic or metal are proposed. However, straws are often used for businesses, and in this case, reuse of straws has limitations in terms of hygiene or the infrastructure of each establishment.

이러한 이유로 최근에는 종이 소재로 구성된 일회용 빨대가 제안되고 있다. 종이 소재로 구성된 일회용 빨대는 인체에 무해할 뿐만 아니라 환경 오염을 최소화한다는 점에서 종래의 플라스틱 소재의 빨대를 대체하기에 충분한 가치가 있다.For this reason, recently, disposable straws made of paper have been proposed. Disposable straws made of paper material are not only harmless to the human body, but also have sufficient value to replace conventional plastic straws in that they minimize environmental pollution.

종이 빨대는 종이띠가 사선 방향으로 복수회 감겨 고정되는 방식으로 제조된다. 그런데 종래의 종이 빨대는 종이띠를 감은 이후에 풀을 발라 경화시켜 형상이 고정된다.Paper straws are manufactured in such a way that a paper strip is wound and fixed a plurality of times in an oblique direction. However, the conventional paper straws are fixed in shape by applying glue after winding the paper strips to harden them.

하지만 이러한 풀 접착 방식의 종이 빨대는 제조 과정 중간에 건조 과정을 거쳐야 한다는 점에서 시간적, 공간적 비효율성을 가져온다. 뿐만 아니라 건조 과정에서 이물질이 붙어 함께 굳어버리는 경우도 있다. 나아가 생산된 종이 빨대가 음료에 투입되어 사용될 때 고형화된 풀이 다시 녹아 음료의 성분을 변질시킬 수도 있다. 또 풀이 쉽게 녹음으로 인해 빨대의 종이에 음료가 쉽게 스며들 우려가 있으며, 이는 빨대 형상을 망가뜨려 제 기능을 수행할 수 없게 만든다.However, these glue-adhesive paper straws bring time and space inefficiency in that they have to go through a drying process in the middle of the manufacturing process. In addition, there are cases in which foreign substances adhere to and harden together during the drying process. Furthermore, when the produced paper straws are put into beverages and used, the solidified grass may melt again and deteriorate the components of the beverages. In addition, there is a risk that beverages may easily seep into the paper of the straw due to the easy melting of the grass, which destroys the shape of the straw and makes it impossible to perform its function.

이러한 문제점을 해결하기 위한 종이 빨대 제조 시스템이 한국등록 특허 제2197630호에 개시되어 있다.A paper straw manufacturing system for solving this problem is disclosed in Korean Patent No. 2197630.

상기 개시된 종이 빨대 제조 시스템은, 적어도 일면에 열접착 코팅 물질이 구비된 상/중/하 종이띠를 구비하는 롤; 롤에서 풀린 상/중/하 종이띠가 외주면에 감기는 맨드릴; 상기 상/중/하 종이띠의 열접착 코팅 물질을 가열하는 히팅부; 상기 맨드릴에 상/중/하 종이띠를 꼬아 예비 빨대를 형성하는 벨트; 및 상기 벨트에 의해 공급된 예비 빨대를 절단하여 빨대를 형성하는 절단부를 포함하는 것으로 되어 있다.The disclosed paper straw manufacturing system includes: a roll having an upper/middle/lower paper strip provided with a heat-adhesive coating material on at least one surface; A mandrel in which upper/middle/lower paper strips unwound from a roll are wound around the outer periphery; a heating unit for heating the heat-adhesive coating material of the upper/middle/lower paper strip; a belt for forming a preliminary straw by twisting upper/middle/lower paper strips on the mandrel; And it is to include a cutting portion for forming a straw by cutting the preliminary straw supplied by the belt.

또한, 상기 개시된 종이 빨대 제조 시스템은, 상/중/하 종이띠 중 상 종이띠가 맨드릴에 붙는 현상을 방지하기 위해, 상/중/하 종이띠에 코팅된 열접착 코팅 물질을 가열하는 히팅부의 입구 측에 배치되어, 상 종이띠의 윗면에 기름을 작은 기름방울로서 자연낙하시켜 도포하는 기름도포부를 구비하고 있다. In addition, in the disclosed paper straw manufacturing system, in order to prevent the upper paper strip from sticking to the mandrel among the upper/middle/lower paper strip, the inlet of the heating unit for heating the thermal adhesive coating material coated on the upper/middle/lower paper strip It is disposed on the side, and has an oil application unit for applying oil by naturally falling as small oil droplets on the upper surface of the upper paper strip.

하지만, 상기 개시된 기름도포부는, 히팅부의 입구 측에 배치되어 있기 때문에, 상 종이띠의 밑면에 코팅된 열접착 코팅층 위에 작은 기름방울로서 낙하된 기름이 히팅부에 들어가게 되면, 열접착 코팅층이 용융되게 되어 매끈한 면으로 되지 않아, 열접착 코팅층 위에 적하된 기름이 열접착 코팅층 위에 미끄러지면서 전반적으로 퍼질 수가 없어, 결국 국소적으로 열접착 코팅층 위에 기름이 존재하게 될 뿐만 아니라, 도포된 기름이 히팅부의 열풍에 의해 가열되어 증발하기 때문에 윤활성이 저하되어, 맨드릴에서 나선형으로 제조되는 빨대가 맨드릴의 길이방향으로 이동하는 데 저항이 발생하여, 상/중/하 종이띠가 맨드릴에서 빨대로서 제대로 감겨지지 않는다고 하는 문제점을 가진다.However, since the disclosed oil application part is disposed on the inlet side of the heating part, when the oil dropped as a small oil drop on the thermal adhesive coating layer coated on the bottom of the upper paper strip enters the heating part, the thermal adhesive coating layer is melted It does not become a smooth surface, and the oil dripped on the heat-adhesive coating layer slides on the heat-adhesive coating layer and cannot spread overall. Eventually, not only does the oil exist on the heat-adhesive coating layer, but also the applied oil As it is heated and evaporated by the hot air, the lubricity is lowered, and resistance occurs in the movement of the straw made in a spiral from the mandrel in the longitudinal direction of the mandrel, so that the upper/middle/lower paper strip is not properly wound as a straw in the mandrel. has a problem that

이러한 문제점을 해결하기 위해, 기름도포부를 히팅부와 맨드릴 사이에 배치하는 방안이 고려될 수 있지만, 상 종이띠의 윗면에 코팅된 열접착 코팅층이 히팅부를 통과하면서 가열 용융되어서 거친면으로 되기 때문에, 기름도포부에 의해 거친면을 가진 열접착 코팅층 위에 작은 기름방울이 자연낙하게 되면, 열접착 코팅층 위에서 기름의 이동성(미끄럼성)이 낮아져 열접착 코팅층 위에 기름이 전체적으로 균일하게 그리고 균일한 뚜께로 도포되지 않아, 이 역시 맨드릴에서 나선형으로 제조되는 빨대가 맨드릴의 길이방향으로 이동하는 데 저항이 발생하여, 상/중/하 종이띠가 맨드릴에서 빨대로서 제대로 감겨지지 않는다고 하는 문제점을 가진다.In order to solve this problem, a method of disposing the oil-applied part between the heating part and the mandrel may be considered, but the thermal adhesive coating layer coated on the upper surface of the upper paper strip is heated and melted while passing through the heating part to become a rough surface. , When small oil droplets fall naturally on the heat-adhesive coating layer with a rough surface by the oil-applied part, the mobility (slidability) of the oil on the heat-adhesive coating layer is lowered, so that the oil is applied uniformly and with a uniform thickness on the heat-adhesive coating layer. This also has a problem that the upper/middle/lower paper strip is not properly wound as a straw in the mandrel because resistance occurs in moving the straw manufactured in a spiral in the mandrel in the longitudinal direction of the mandrel.

본 발명은 상기된 문제점을 해결하는 것에 과제를 가진다.The present invention has a problem in solving the above problems.

본 발명은, 기름도포부를 히팅부와 맨드릴 사이에 배치시키되, 작은 기름방울을 자연낙하시키는 액적공급부; 액적공급부에서 낙하하는 액적을 받아내는 액적수용부; 및 상기 액적수용부에 유통하게 접속되어 상기 액적수용부에 저장된 기름에 적시어져서 상기 상 종이띠의 윗면에 접촉하여 기름을 도포하는 붓수단을 기름도포부가 포함하게 함으로써 상기 과제를 해결할 수 있다.The present invention, doedoe disposing the oil application part between the heating part and the mandrel, a droplet supply part for naturally falling small drops of oil; a drop receiving unit for receiving a drop falling from the droplet supply unit; And it is possible to solve the above problem by including a brush means for applying oil in contact with the upper surface of the paper strip while being circulated in the droplet receiving section and soaked in the oil stored in the droplet receiving section to include the oil applying section.

본 발명은, 기름도포부를 히팅부와 맨드릴 사이에 배치되고 그리고 상 종이띠의 윗면에 코팅된 열접착 코팅층이 히팅부를 통과하면서 가열 용융되어서 거친면으로 되어도, 기름도포부에 의해 거친면을 가진 열접착 코팅층 위에 기름을 전체적으로 균일하게 그리고 균일한 두께로 붓칠하여 도포할 수 있기 때문에, 맨드릴에서 나선형으로 제조되는 빨대가 맨드릴의 길이방향으로 이동하는 데 저항이 없이, 상/중/하 종이띠가 맨드릴에서 빨대로서 제대로 감겨지게 할 수 있다.In the present invention, the oil-applied part is disposed between the heating part and the mandrel and the heat-adhesive coating layer coated on the upper surface of the upper paper strip is heated and melted while passing through the heating part to become a rough surface, Since oil can be applied uniformly and evenly on the heat-adhesive coating layer as a whole, there is no resistance to the movement of the straw made spirally from the mandrel in the longitudinal direction of the mandrel, and the upper/middle/lower paper strips A straw on the mandrel allows it to be properly wound.
