Description
본 발명은 곡물건조장치 내에 에어를 안내하는 에어웨이파이프의 제조방법에 관한 것으로서, 더욱 상세하게는 철판에 다수의 에어안내공을 타공한 후 양단을 원통형으로 롤 성형 용접함으로써, 제작단가를 낮추고 제작성을 향상시켜 제조원가를 절감할 수 있는 에어웨이파이프의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing an airway pipe for guiding air in a grain drying apparatus, and more specifically, by drilling a plurality of air guide holes on a steel plate, roll forming and welding both ends in a cylindrical shape, lowering the manufacturing cost and manufacturability It relates to a method for manufacturing an airway pipe that can reduce the manufacturing cost by improving the.
일반적으로, 산지에서 수확한 벼, 보리 등의 곡물류는 소비자에게 도달하기 까지의 보관 및 운송을 위해서 건조가 필수적이다. 왜냐하면, 산지에서 수확한 벼, 보리 등의 곡물류는 손상없이 보관 및 운송을 하기에는 지나치게 많은 수분 함량을 갖고 있기 때문이다. 즉, 산지에서 수확한 벼, 보리 등의 곡물류는 약 20~30%의 수분 함량을 갖는데, 이러한 수분 함량을 갖는 곡물류는 저장을 위한 보관시에 쉽게 변질되기 때문에 보관이 어렵다.In general, grains such as rice and barley harvested from the mountain region are required to be dried for storage and transportation until reaching the consumer. This is because grains such as rice and barley harvested from the mountain region have too much moisture to be stored and transported without damage. That is, grains such as rice and barley harvested from the mountain region have a water content of about 20 to 30%, and grains having such water content are difficult to store because they are easily deteriorated during storage for storage.
벼, 보리 등의 곡물류가 함유하는 수분 함량은 식미(食味)를 좌우하는 중요한 요소 중 하나이고, 품질의 유지 및 벌레의 발생을 방지하는데 있어서도 매우 중요하다. 그런데, 원하는 수치이상의 수분 함량을 갖는 벼나 보리로 밥을 지으면 내부 전분질이 용출되고 밥알의 원형을 그대로 유지하지 못하므로 식미가 크게 저하된다. 따라서, 산지에서 수확한 벼, 보리 등의 곡물류는 소비자에게 전달하기 전에 안전한 저장과 운송 및 식미의 보존을 위해서 약 14~15.5%의 수분 함량을 갖도록 건조되어야 한다.The moisture content of grains such as rice and barley is one of the important factors that influence the taste, and is also very important in maintaining the quality and preventing the occurrence of insects. However, when rice is cooked with rice or barley having a moisture content of more than the desired value, the internal starch is eluted and the original shape of the rice grains is not retained as it is, and the taste is greatly reduced. Therefore, grains such as rice and barley harvested from mountain areas should be dried to have a moisture content of about 14 to 15.5% for safe storage, transportation and preservation of food before delivery to consumers.
이와 같이 알맞은 식미 보존을 위해서 최근에는 다양한 형태의 곡물건조장치가 널리 사용되고 있다. 이러한 곡물건조장치 원통형 본체, 원통형 본체의 개방된 상부를 덮는 지붕 구조물, 원통형 본체의 내측 하부에 배치된 곡물 배출 스크루장치, 원통형 본체 외부에 수직하게 배치된 버킷 엘리베이터 및 버킷 엘리베이터 하부에 배치된 바닥형 곡물 투입장치를 포함한다. 또한, 곡물건조장치는 원통형 본체의 상부에 배치된 곡물 투입 스크루장치, 배분기, 곡물을 저장하기 위한 건조저장실, 건조 열풍을 발생시키기 위한 보조열원 및 송풍장치, 건조저장실 내에 저장된 곡물을 교반하기 위한 교반장치 및 곡물저장장치의 전체적인 작동을 제어하기 위한 제어장치를 포함한다. 이때, 건조저장실의 하측에는 타공망으로 형성된 바닥판이 배치되며, 바닥판의 가장자리에는 일정간격을 유지하면서 방사상으로 배치되는 다수의 에어웨이파이프가 설치된다. 이러한 에어웨이파이프에는 다수의 에어안내공이 형성되면서 고정고리에 의해서 본체의 벽면에 고정된다. 전술한 에어웨이파이프를 제조하기 위해서는 백관 파이프 25A 2.3t를 구매하여 적절하게 절단하고 마구리부는 프레싱(pressing)하여 공기의 배출을 막으며 파이프 좌, 우에 피치 30 간격으로 직경 2.2의 에어안내공을 천공하였다.Recently, various types of grain drying apparatuses have been widely used for proper food preservation. The grain drying apparatus cylindrical body, the roof structure covering the open top of the cylindrical body, the grain discharge screw device disposed on the inner lower portion of the cylindrical body, the bucket elevator vertically disposed outside the cylindrical body and the bottom type disposed below the bucket elevator Includes grain feeders. In addition, the grain drying apparatus is a grain input screw device disposed on the upper portion of the cylindrical body, the distributor, a dry storage room for storing grain, an auxiliary heat source and blower for generating dry hot air, agitating for stirring the grain stored in the dry storage room A control device for controlling the overall operation of the device and the grain storage device. At this time, a bottom plate formed of a perforated network is disposed below the dry storage chamber, and a plurality of airway pipes disposed radially while maintaining a predetermined interval are installed at the edge of the bottom plate. The airway pipe is fixed to the wall surface of the body by a fixing ring while a plurality of air guide holes are formed. In order to manufacture the above airway pipe, 2.3t of white pipe 25A was purchased and cut appropriately, and the copper part was pressed to prevent the discharge of air, and the air guide hole having a diameter of 2.2 was drilled at intervals of 30 pitches on the left and right sides of the pipe. .
그러나 전술한 에어웨이파이프에 에어안내공의 직경이 너무 작아서 다축드릴을 사용하지 못하여 작업자가 일일이 수동 드릴을 이용하여 드릴작업을 하기 때문에 제작시간이 많이 소요될 뿐만 아니라 제작단가가 상승하는 문제점이 있었으며, 또한 드릴작업시 드릴이 자주 파손되는 문제점이 있었다.However, since the diameter of the air guide hole is too small in the above-described airway pipe, the operator cannot drill the drill using a manual drill.

이하, 본 발명의 바람직한 일 실시예에 따른 에어웨이파이프의 제조방법에 대해 설명한다.Hereinafter, a method of manufacturing an airway pipe according to an exemplary embodiment of the present invention will be described.
곡물건조장치(도시되지 않음) 내의 곡물저장실의 바닥면 가장자리에 방사상으로 다수가 배치되어 곡물저장실의 내부와 외부 기온차에 의한 결로현상을 방지하하도록 에어를 안내하는 에어웨이파이프를 제조하기 위해서는 권취된 철판을 언코일러에 장착한다(단계 S1). 이때, 권취된 철판은 두께 2.3t, 폭 82.5㎜의 용융아연도금강판(Gi)을 채택한다.In order to produce airway pipes that guide air to prevent condensation caused by temperature differences between the interior and exterior of the grain storage room, a plurality of radially disposed at the bottom edge of the grain storage room in the grain drying apparatus (not shown) Is mounted on the uncoiler (step S1). At this time, the wound iron sheet adopts a hot dip galvanized steel sheet Gi having a thickness of 2.3t and a width of 82.5mm.
이와 같이 권취된 철판이 언코일러에 장착되면(단계 S1), 철판을 벗겨내면서 고속 타공 프레스 측으로 이송시킨 후(단계 S2), 고속 타공 프레스를 작동시켜 다수의 에어안내공을 형성한다(단계 S3). 이때, 에어안내공의 직경은 2,2㎜이며, 에어안내공의 중심은 철판의 일단 및 타단측에서 내측으로 20.625㎜에 위치하면서 피치 30㎜ 간격으로 연속되게 형성된다. 즉, 에어안내공은 철판을 따라서 복수의 열(列)을 가지며 형성된다.When the wound iron plate is mounted on the uncoiler (step S1), the iron plate is peeled off and transferred to the high speed punching press side (step S2), and then the high speed punching press is operated to form a plurality of air guide holes (step S3). . At this time, the diameter of the air guide hole is 2,2mm, the center of the air guide hole is formed continuously at intervals of 30mm pitch while being located at 20.625mm inward from one end and the other end side of the iron plate. That is, the air guide hole is formed with a plurality of rows along the iron plate.
전술한 바와 같이 철판에 다수의 에어안내공이 형성되면(단계 S3), 에어안내공이 형성된 철판을 다시 권취한다(단계 S4). 이렇게 권취된 철판은 다시 언코일러에 장착한 상태 하에서 원형 롤 성형기 측으로 이송시킨 후(단계 S5), 원형 롤 성형기를 작동시켜 철판의 양단을 서로 용접 고정시킨다(단계 S6). 이때, 철판의 양단이 용접 고정됨에 따라서 철판은 원통형상을 가지게 되며, 복수의 열(列)로 타공된 에어안내공은 방사상 서로 마주보도록 배치된다.As described above, when a plurality of air guide holes are formed in the iron plate (step S3), the iron plate on which the air guide holes are formed is wound again (step S4). The iron plate thus wound is transferred to the circular roll forming machine side under the state of being mounted on the uncoiler again (step S5), and then the two ends of the iron plates are welded and fixed to each other by operating the circular roll forming machine (step S6). At this time, as both ends of the iron plate is welded and fixed, the iron plate has a cylindrical shape, and the air guide holes perforated in a plurality of rows are disposed to face each other in a radial direction.
이렇게 철판의 양단이 용접 고정되면 원통형상을 가지게 되면(단계 S6), 원형 롤 성형기에서 배출되는 원통형 철판을 5.4~6.0m로 1차 절단한 후(단계 S7), 다시 5.4~6.0m의 원통형 철판을 2.7m 또는 3.0m로 2차 절단한다(단계 S8). 이와 같이 2차 절단된 원통형 철판의 일단은 공기 누출을 방지할 수 있도록 가압 프레스로 가압하여 에어웨이파이프를 완성한다(단계 S9).When both ends of the iron plate are welded and fixed, the cylindrical plate (step S6) is first cut to the cylindrical iron plate discharged from the circular roll forming machine to 5.4 to 6.0 m (step S7), and then again to the 5.4 to 6.0 m cylindrical iron plate. Is cut second to 2.7 m or 3.0 m (step S8). One end of the secondary cut cylindrical iron plate in this way is pressurized with a pressure press to prevent air leakage to complete the airway pipe (step S9).
전술한 바와 같이, 본 발명에 따른 에어웨이파이프는 종래에 에어안내공을 형성하기 위해서 필수적으로 사용하던 드릴작업을 고속 타공 프레스를 이용하여 형성함으로써, 작업자의 안전사고를 방지할 수 있을 뿐만 아니라 가공시간 및 제조원가를 절감할 수 있는 잇점이 있다.As described above, the airway pipe according to the present invention by using a high-speed punching press to form a drill operation, which is essential to the conventional air guide hole, it is possible to prevent the safety accident of the operator as well as processing time And there is an advantage that can reduce the manufacturing cost.
상기에서는 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 해당기술 분야의 숙련된 당업자는 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터벗어나지 않는 범위내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art can variously modify and change the present invention without departing from the spirit and scope of the invention described in the claims. You will understand.
