Description

화이버 드럼{FIBER DRUM}Fiber Drums {FIBER DRUM}

본 발명은 산업분야에서 제품이나 자재를 수납 보관하는데 사용되는 화이버 드럼에 있어서, 금속밴드를 사용하지 않는 순후지제 화이버 드럼에 관한 것으로, 더욱 자세하게는 화이버 드럼의 구조를 개선하여 자체의 강도를 향상시키고 사용 후 폐기되는 화이버 드럼의 파쇄 및 해섬작업성을 높여 재생지의 생산성을 향상시킬 수 있게 한 화이버 드럼에 관한 것이다.
The present invention relates to a fiber drum made of pure fuji which does not use a metal band in a fiber drum used for storing and storing a product or material in an industrial field, and more particularly, to improve its strength by improving the structure of the fiber drum. The present invention relates to a fiber drum capable of improving the productivity of recycled paper by increasing the crushing and seam workability of the fiber drum which is discarded after use.

통상의 화이버 드럼은 공개특허공보 제10-2015-0128100호에 개시된 바와 같이, 드럼 본체의 하단에 밑판을 대고 금속밴드를 둘러씌워 컬링하고, 드럼 본체의 상단에는 별도의 금속밴드를 둘러씌워 컬링하여 드럼 본체의 상단과 하단을 보강한 것이다.A conventional fiber drum is curled by covering a metal band with a bottom plate on the bottom of the drum body as disclosed in Korean Patent Laid-Open Publication No. 10-2015-0128100, and curling by covering a separate metal band on the top of the drum body. The top and bottom of the drum body is reinforced.

다시 말해서 종래의 화이버 드럼의 구조는 몸체는 후지재질로 제작한 지관이고, 드럼 몸체의 상단과 하단은 별도의 금속밴드를 결합하여 일체로 사용하도록 구성한 것이다. In other words, the structure of a conventional fiber drum is a body made of Fuji material, the top and bottom of the drum body is configured to be used in combination by combining a separate metal band.

내용물을 다 비운 화이버 드럼은 폐기한다. 폐화이버 드럼을 재생하려면 위 아래 금속밴드를 제거해야 한다. 위아래 금속밴드는 바로 밑 또는 바로 윗부분의 화이버 드럼 부분을 톱이나 전동식 절단휠로 절단하여 분리해 제거하는 데, 절단과정에서 종이가루가 날려 분리작업장 주변을 오염시키고 작업자의 건강도 해친다.Discard the fiber drum after emptying its contents. To regenerate the waste fiber drums, the top and bottom metal bands must be removed. The upper and lower metal bands are separated and removed by cutting the fiber drum part directly below or above with a saw or an electric cutting wheel.

또, 금속밴드를 분리하는 과정에서 상부 금속밴드는 하단이 그리고 하부 금속밴드는 상단이 톱날이나 절단휠의 연마립에 긁힌 금속가루가 화이버 드럼 본체의 절단면 쪽으로 옮겨 묻어 박히기도 하고 화이버 드럼의 표면에 달라 붙어 오염시키기도 하는 데, 화이버 드럼의 절단면과 표면에서 제거하기가 쉽지 않다. 금속가루가 섞인 채로 화이버 드럼을 해섬하면 생산한 재생지의 품질이 저하된다.Also, in the process of separating the metal band, the upper metal band is at the bottom and the lower metal band is at the top, and the metal powder scratched by the abrasive grain of the saw blade or the cutting wheel is transferred to the cutting surface of the fiber drum body, and the surface of the fiber drum is embedded. It also sticks to and contaminates, making it difficult to remove from the cutting surface and surface of the fiber drum. Degrading fiber drums with mixed metal deteriorates the quality of recycled paper.

게다가, 화이버 드럼 본체는 종이를 여러 겹 겹쳐서 둥글게 말아 접합한 후지이기 때문에 절단이 용이치 않고, 절단도 오래 걸린다.In addition, since the fiber drum main body is Fuji, which is rolled up by laminating a plurality of sheets of paper together, it is not easy to cut and takes a long time.

이 때문에 화이버 드럼 수거업체는 낮은 재생수익성이란 이유를 들어 빈 화이버 드럼의 수거를 매우 꺼려하기 때문에 사용자측에서는 하는 수 없이 그냥 폐기하게 된다. 화이버 드럼 본체의 재생 경제성이 높음에도 어쩔 수 없이 폐기하는 건 자원낭비가 아닐 수 없다. 폐금속밴드의 처리도 문제다.As a result, fiber drum collectors are very reluctant to collect empty fiber drums for reasons of low reproducibility. Despite the high economical efficiency of the fiber drum body, it is a waste of resources. The treatment of waste metal bands is also a problem.

한편, 일반 화이버 드럼에서, 하단 금속밴드는 화이버 드럼 본체의 하단 속으로 삽입한 바닥판의 가장자리를 턱걸림시켜 위로 밀려 올라가지 못하게 저지하는 환상 요홈턱이 형성되어 있다. 이 환상 요홈턱은 하단 금속밴드의 상단에 형성된 내향 환상 플렌지가 걸려 밑빠짐되지 않게 하는 그루브(환상 요홈턱)를 가공할 때 형성되는 것이다. On the other hand, in the general fiber drum, the lower metal band is formed in the annular groove jaw to stop the pushing up the edge of the bottom plate inserted into the lower end of the fiber drum body. This annular groove jaw is formed when processing a groove (annular groove jaw) which prevents the inward annular flange formed on the upper end of the lower metal band from being caught.

그루브는 하단 금속밴드 상단의 환상 플렌지의 두께보다도 높다. 화이버 드럼 본체의 하단으로 바닥판을 삽입하고, 화이버 드럼 본체의 하단에 하단 금속밴드를 둘러 씌워 바닥판이 밑빠짐되지 않도록 했을 때 상기 내향테는 그루브의 하단에 걸리고, 내향 환상 플렌지가 차지하고 남은 그루브의 윗부분은 여백으로 남는다. 문제는 이 여백 부분이다. 화이버 드럼을 적층하면 상층 화이버 드럼의 무게가 하층 화이버 드럼에 그대로 재하되어 상기 그루브의 여백 부분이 주저앉고 변형된다.The groove is higher than the thickness of the annular flange on the top of the bottom metal band. When the bottom plate is inserted into the bottom of the fiber drum body and the bottom metal band is wrapped around the bottom of the fiber drum body to prevent the bottom plate from falling out, the inward frame is caught by the bottom of the groove, and the inward annular flange occupies the remaining groove. The top part is left blank. The problem is this margin. When the fiber drums are stacked, the weight of the upper fiber drum is loaded on the lower fiber drum as it is, so that the margin part of the groove falls and deforms.

화이버 드럼의 적층수가 증가할수록 이런 현상이 두드러지며, 심한 경우에는 상층 화이버 드럼이 눈에 띌 정도로 기울어져 적층상태가 와해될 수 있다.
This phenomenon becomes more pronounced as the number of fiber drums is increased, and in severe cases, the upper fiber drums may be noticeably tilted and the stacking state may be degraded.

본 발명의 목적은 금속 밴드를 전혀 사용하지 않고 순수 후지(종이)재질로 제작되는 화이버 드럼을 제공하는 것이다. An object of the present invention is to provide a fiber drum made of pure Fuji (paper) material without using any metal band.

본 발명의 다른 목적은 화이버 드럼의 상단 및 하단에 설치하던 금속밴드를 대신하여 드럼 본체의 상단 및 하단 컬링부로 대체한 새로운 구조의 화이버 드럼으로서, 적층하중에도 화이버 드럼의 하단부에 주어진 바닥판 윗빠짐방지용으로서 외형상으론 그루브형인 내향 요홈턱과 버팀형 직벽부에 의해서 주저앉지 않는 튼튼한 화이버 드럼을 제공하는 데 있다.
Another object of the present invention is a fiber drum having a new structure in which the upper and lower curling portions of the drum body are replaced with metal bands installed on the upper and lower ends of the fiber drum, and a bottom plate is provided on the lower end of the fiber drum even in a laminated load. As a preventive aspect, the present invention provides a sturdy fiber drum which does not sit down by the grooved inward groove jaw and the brace-shaped straight wall portion.

상기 목적을 달성하기 위해서 본 발명은, 화이버 드럼 본체에서 상단 및 하단 금속밴드를 배제하여 폐기시 절단 및 파쇄를 용이토록 하고, 특히 화이버 드럼 본체의 하단으로 삽입한 밑판이 윗빠짐되지 않도록 저지하는 내향 요홈턱을 방사상으로 형성하되, 내향 요홈턱 사이마다 직벽부를 형성하여 내향 요홈턱에 대하여 지주역할을 해 상대적인 개념인 그루브를 보호하는 버팀기둥으로 작용하도록 하여 적층하중에도 화이버 드럼의 그루브(=내향 요홈턱)가 주저앉지 못하도록 방지하는데 탁월한 효과가 있다.
In order to achieve the above object, the present invention excludes the upper and lower metal bands from the fiber drum body to facilitate cutting and shredding during disposal, and particularly to prevent the bottom plate inserted into the lower end of the fiber drum body from falling out. The grooved jaw is formed radially, but a straight wall is formed between each inward grooved jaw to act as a support pillar to protect the groove, which is a relative concept, and act as a support pillar to protect the groove, which is a relative concept. Groove jaw) has an excellent effect to prevent sitting.

본 발명의 순후지제 화이버 드럼은 상단은 물론 하단 보강용 금속밴드까지 배제되고 이들 금속밴드의 기능이 상단 및 하단 컬링부로 대체됨으로써 화이버 드럼의 생산성이 제고되고, 제조원가는 대폭 경감되며, 폐화이버 드럼에서 금속밴드를 제거하는 노력과 비용이 절감되는 것과 함께, 내용물이 담긴 화이버 드럼을 종렬로 적층했을 때 화이버 드럼의 하단에 집중되는 적층하중을 내향 요홈턱 사이의 버팀형 직벽 부분이 감당하여 내향 요홈턱에 상대적 개념인 그루브가 주저앉지 않게 됨으로써 화이버 드럼의 하단부측 그루브의 변형이 방지된다.
The fiber fiber drum of the present invention is excluded from the top as well as the bottom reinforcing metal bands, and the functions of these metal bands are replaced by the upper and lower curling parts, thereby improving the productivity of the fiber drums, and reducing the manufacturing cost significantly. In addition to reducing the effort and cost of removing the metal bands in the system, when the fiber drums containing the contents are stacked in a row, the brace-type straight wall portion between the inward grooves bears the lamination load concentrated at the bottom of the fiber drums. Since the grooves, which are a concept relative to the grooves, do not sit down, deformation of the grooves on the lower end side of the fiber drum is prevented.

도 1은 본 발명에 의한 화이버 드럼(1)의 정면도이고, 도 2는 동 평면도이다. 이들 그림에서, 화이버 드럼(1)은 상단 컬링부(2)와 하단 컬링부(3)를 갖는다. 상단 컬링부(2)와 하단 컬링부(3)는 각 단부를 내향 절곡하여 각(角)부의 강도를 높인 것으로, 종래의 상부 및 하부 금속밴드 대용이다.1 is a front view of a fiber drum 1 according to the present invention, and FIG. 2 is a plan view of the same. In these figures, the fiber drum 1 has a top curling part 2 and a bottom curling part 3. The upper curling section 2 and the lower curling section 3 bend each end inward to increase the strength of each section, and are substituted for the conventional upper and lower metal bands.

하단 컬링부(3)의 바로 윗 부분에는 외형상으론 오목한 그루브형태이고 위에서 내려다보면 화이버 드럼 본체(1)의 내측을 향하여 향심방향으로 튀어나온 형태의 내향 요홈턱(4)이 형성되어 있다. 이 내향 요홈턱(4)은 화이버 드럼 본체(1)의 원주를 수 등분한 곳마다 하나씩 형성하여 바닥판의 가장자리가 확실히 윗걸림되도록 해 설계치 이상으로 삽입되지 못하게 저지하는 것으로, 종래의 환상 그루브와 이에 의해 형성되는 바닥판용 걸림턱을 갈음하는 듯 보일 수 있지만, 비환상 그루브-걸림턱인 점이 특징이다.The inward groove jaw 4 of the lower curling part 3 is formed in a concave groove shape and protrudes inwardly toward the inner side of the fiber drum body 1 when viewed from above. The inward groove jaw 4 is formed by circumferentially circumferentially the fiber drum body 1 so that the edge of the bottom plate is securely caught so as to prevent insertion beyond the design value. Although it may seem to replace the locking jaw for the bottom plate formed by this, it is characterized by a non-cyclic groove-hanging jaw.

도 3 및 도 4에서와 같이, 상기 내향 요홈턱(4)은 하단 컬링부(3)의 경계인 수평부(5)를 천정으로 하여 바닥판의 삽입깊이를 결정하고, 바닥판의 끝단을 물어서 잡아주는 포?(공간)을 형성한다.3 and 4, the inward groove jaw 4 determines the insertion depth of the bottom plate with the horizontal portion 5, which is the boundary of the lower curling portion 3, as a ceiling, and bites the end of the bottom plate. The state forms a pore.

이 수평부(5)의 내측단에서 위쪽을 향해 외측으로 구배진 경사벽(6)을 두어 상기 수평부(5)가 원형을 유지하도록 돕는다.An inclined wall 6 that is sloped outward from the inner end of the horizontal part 5 upwards helps the horizontal part 5 to maintain a circular shape.

일정한 크기로 형성된 상기 내향 요홈턱(4) 사이마다 직벽부(7)가 형성되며, 이 직벽부(7)는 화이버 드럼 본체(1)의 외형대로 남겨 상기 내향 요홈턱(4), 특히 경사벽(6)이 주저앉지 못하게 지지하는 기둥 역할을 하도록 한다.A straight wall portion 7 is formed between each of the inwardly recessed recesses 4 formed in a predetermined size, and the straight wall portion 7 is left in the shape of the fiber drum body 1 and the inwardly recessed recess 4, in particular, an inclined wall. Make it a pillar to support (6).

밑판(8)은 가장자리를 아래로 직각되게 접은 테(9)의 외주면이 하단 컬링부(3)로 가공하기 이전의 화이버 드럼 본체의 하단을 통해 올려 끼우고, 상기 테(9)를 하단 컬링부(3)와 함께 내향 절곡하여 화이버 드럼을 구성한다. 기밀성 유지와 함께 결합강도를 높이려면 하단 컬링부(3)를 컬링하기 전에 화이버 드럼 본체의 하단 내주면 또는 상기 테(9)의 외주면에 접착제를 도포하여 접합한다.The bottom plate 8 is fitted with the outer circumferential surface of the rim (9) folded at its right angles downward through the lower end of the fiber drum body before being processed into the lower curling portion (3), and the rim (9) is lower curled portion. Bending inward with (3) constitutes a fiber drum. In order to increase the bonding strength with airtightness, the adhesive is applied to the lower inner circumferential surface of the fiber drum body or the outer circumferential surface of the frame 9 before the lower curling portion 3 is curled.

참고로, 하단 컬링부(3)의 내측에 밑판(8)의 테(9)가 함께 컬링된 상태에서 테(9)는 하단 컬링부(3)를 보강하는 심(芯)의 역할을 한다. 하단 컬링부(3)의 단부가 닿은 밑판(8) 부위에 접착제를 도포하여 기밀성을 강화할 수도 있다. 다만, 상단 컬링부(2)는 내용물을 정량 장입하여 포장한 후 덮개를 씌워야 하므로 덮개 없이 그대로 단순히 컬링하여 상단을 보강하는 것으로 마감한다.For reference, in the state in which the rims 9 of the bottom plate 8 are curled together inside the lower curling portion 3, the rim 9 serves as a shim to reinforce the lower curling portion 3. An airtightness can also be strengthened by applying an adhesive to the bottom plate 8 part where the end of the lower curling part 3 has touched. However, the top curling portion (2) is closed by reinforcing the top by simply curling as it is without a cover, so that the cover must be covered after packing the contents into a fixed amount.

이렇게 완성한 화이버 드럼에 내용물을 정량 장입하고, 상단에 도시하지 아니한 후지제 덮개를 씌운 다음에 금속제 탈착형 환상 클램프 등의 결속수단을 둘러씌우고 잠가서 포장상태를 안정시키는 것은 종래의 금속밴드 장착형 화이버 드럼과 같다. It is a conventional metal band-mounted fiber drum to stabilize the packaging by quantitatively loading contents into the completed fiber drum, putting a Fuji cover (not shown) on the top, and enclosing the binding means such as a metal detachable annular clamp. Same as

화이버 드럼(1)의 하단에서 보강용 금속밴드가 화이버 드럼 본체의 하단 컬링부(3)로 대체되고, 하단 컬링부(3)의 바로 윗 부분에 화이버 드럼 본체의 원주를 등분한 곳마다 주어진 외형상으론 그루브형이고 내측 형상적으로는 내향 요홈턱(4)에 있어서 수평부(5)는 바닥판의 삽입깊이를 확실하게 결정하는 받침 역할을 하고, 그 경사벽(6)은 상기 내향 요홈턱(4)의 형상이 유지되도록 하는 동시에 내향 요홈턱(4) 사이의 직벽부(7)는 내향 요홈턱(4)에 대하여 지주역할을 하도록 구성한 본 발명의 화이버 드럼(1)은 상단은 물론 하단 보강용 금속밴드까지 배제되고 이들 금속밴드의 기능이 상단 및 하단 컬링부로 대체되어 화이버 드럼의 생산성 제고와 함께 제조원가 절감효과가 명확하고, 게다가 폐화이버 드럼을 재활용하기 위해서 금속밴드를 제거하는 노력과 비용을 절감하는 데다, 내용물이 담긴 화이버 드럼을 종렬로 적층했을 때 화이버 드럼의 하단에 집중되는 적층하중을 내향 요홈턱 사이의 직벽 부분과 외형상 그루브 형태인 상기 내향 요홈턱이 주저앉지 못하게 저지하는 함으로써 화이버 드럼의 요홈턱, 요홈턱의 외형인 그루브의 변형이 방지된다.In the lower part of the fiber drum 1, a reinforcing metal band is replaced by the lower curling part 3 of the fiber drum body, and the shape is given wherever the circumference of the fiber drum body is equally divided into the upper part of the lower curling part 3. In the groove-shaped and inner shape, the inward groove jaw 4 has a horizontal portion 5 as a support to reliably determine the insertion depth of the bottom plate, and the inclined wall 6 is the inward groove jaw ( While maintaining the shape of 4), the straight wall portion 7 between the inward groove jaw 4 serves as a support for the inward groove jaw 4, the fiber drum 1 of the present invention is reinforced as well as the top The use of metal bands is eliminated and the functions of these metal bands are replaced by upper and lower curling parts, which increases the productivity of the fiber drum and reduces the manufacturing cost. In addition, efforts are made to remove the metal band to recycle waste fiber drums. In addition to reducing costs, when the fiber drums containing the contents are stacked in a row, the stacking load concentrated at the lower end of the fiber drum is prevented from falling down between the straight wall portion between the inward groove and the inward groove. By doing so, deformation of the grooves, which are the contours of the grooved jaw of the fiber drum and the grooved jaw, is prevented.
