일반적으로 문서세단기는 사무실이나 은행 등에서 보안을 요하는 문서나 거래명세서 및 마이크로 필름 등을 잘게 절단하거나, 골판지 박스나 폐문서 등을 재활용할 목적으로 잘게 절단하는 기기를 말한다.In general, a document shredder is a machine that finely cuts documents, transaction specifications and microfilms that require security in offices or banks, or cuts them for the purpose of recycling corrugated cardboard boxes or waste documents.

최근에 기술이 발달함으로 인해서 문서보안을 철저히 하는데 관심이 많아지고, 특히 사용 후에 폐기되는 폐문서를 잘게 절단하여 보안성을 높이고 있다.Due to recent developments in technology, there is a growing interest in thoroughly document security, and in particular, the waste documents that are discarded after use are severed to improve security.

종래의 문서세단기는 도 1과 같이, 상단에 문서투입구(11)가 형성되고, 전방하단에 도어가 형성된 박스형상의 케이스(10)와; 상기 케이스(10)의 내부 상단에 다수개의 절단칼날이 한 쌍의 커터축에 고정되어 구동모터에 의해 상호 교차 회전하면서 문서투입구(11)를 통해 인입되는 폐문서를 잘게 절단하는 절단장치(20)와; 상기 절단장치(20)의 하단에 형성되고, 절단장치(20)에 의해 절단된 폐문서칩이 쌓일 수 있도록 한 폐문서함(30)이 형성된다.1, a conventional document separator includes a box-shaped case 10 having a document inlet 11 formed at an upper end thereof and a door formed at a lower end thereof; A plurality of cutting blades are fixed to a pair of cutter shafts at an inner upper end of the case 10 and are cut by a cutting device 20 for finely cutting a waste document drawn through the document inlet 11 while cross- Wow; A waste paper tray 30 is formed at the lower end of the cutting apparatus 20 so that waste paper chips cut by the cutting apparatus 20 can be stacked.

종래의 문서세단기는 대한민국특허청 등록특허공보 제0660647호, 등록실용신안공보 제0228707호, 제0885048호 등에 개시된 바 있다.A conventional document separator has been disclosed in Korean Patent Registration No. 0660647, Registered Utility Model No. 0228707, No. 0885048, and the like.

최근에는 문서폐기에 대한 의식이 높아져서 많은 양의 폐문서를 한꺼번에 처리할 수 있도록 대형으로도 많이 개발되고 있다.In recent years, awareness of document disposal has increased, and large-scale development has been made so that a large amount of waste documents can be processed at a time.

그러나, 종래의 대형 문서세단기용 절단칼날은 다음과 같은 문제점이 있었다. However, the conventional cutting knife for a large-sized document cutting machine has the following problems.

*(1) 절단칼날이 상호 교차회전하면서 사이를 통과하는 폐문서를 절단할 때 절단칼날의 칼날팁의 끝단에 폐문서가 전체적으로 접촉하여 끊어내기 때문에 소음이 크다.* (1) When cutting a waste paper passing between the cutting blades crossing each other, the waste paper is entirely brought into contact with the tip of the blade tip of the cutting blade and cut off, resulting in a large noise.

(2) 폐문서가 절단칼날의 칼날팁의 끝단과 전체적으로 접촉하여 끊어내기 때문에 모터의 부하가 커서 내구성이 떨어진다.(2) Since the waste paper is entirely in contact with the tip of the blade tip of the cutting blade and cut off, the load of the motor is large, and durability is deteriorated.

상기한 문제점을 해결하기 위해서, 본 발명은 원통형의 박판의 가운데에 축삽입홀이 형성되고, 상기 몸체의 주연부에 돌출되는 칼날팁이 형성되는 일반적인 문서세단기용 절단칼날에 있어서,In order to solve the above problems, the present invention provides a cutting blade for a general document shredder, in which a shaft insertion hole is formed in the center of a cylindrical thin plate, and a blade tip protruding from the periphery of the body is formed,

상기 칼날팁의 끝단의 측면에 경사부가 형성된 것을 특징으로 한다.And an inclined portion is formed on a side surface of an end of the blade tip.

본 발명의 문서세단기용 절단칼날에 의하면 다음과 같은 효과가 발생한다.According to the cutting blade for a document separator of the present invention, the following effects are produced.

(1) 절단칼날이 상호 교차회전하면서 사이를 통과하는 폐문서를 절단할 때 절단칼날의 칼날팁의 끝단이 폐문서에 점접촉 한 후 경사면을 따라 연속하여 찢어지기 때문에 소음이 작다.(1) The noise is small because the end of the blade tip of the cutting blade makes a point contact with the closed document and then tears continuously along the inclined plane when cutting the cut paper passing through the cutting blade while mutually crossing the cutting blade.

(2) 폐문서가 절단칼날의 칼날팁의 끝단에 점접촉하여 연속하여 찢어지기 때문에 모터의 부하를 줄여서 내구성이 증가한다.(2) Since the waste paper is torn continuously by point contact with the tip of the blade tip of the cutting blade, the load of the motor is reduced and the durability is increased.

본 발명은 원통형의 박판의 가운데에 축삽입홀(110)이 형성되고, 몸체(100)의 주연부에 돌출되는 칼날팁(120)이 형성되는 일반적인 문서세단기용 절단칼날(150)에 있어서,The present invention is a cutting blade 150 for a general document shredder in which a shaft insertion hole 110 is formed in the center of a cylindrical thin plate and a blade tip 120 protruding from the periphery of the body 100 is formed,

상기 칼날팁(120)의 끝단의 측면에 경사부(122)가 형성된다.An inclined portion 122 is formed on a side surface of an end of the blade tip 120.

상기 절단칼날은 칼날팁(120)의 개수에 따라서 폐문서칩의 크기가 결정되는데, 보안도에 따라서 칼날팁(120)을 형성한다. The cutting blade determines the size of the closed document chip according to the number of the blade tips 120, and forms the blade tip 120 according to the degree of security.

상기 칼날팁(120)은 회전방향으로 기울어져 형성되는데, 회전방향에서 살펴볼 때, 후면에 문서의 배출이 용이하도록 유선형의 배출부(121)가 형성된다. The blade tip 120 is formed to be inclined in the rotating direction. When viewed in the rotating direction, a streamlined discharge portion 121 is formed on the rear surface to facilitate the discharge of the document.

상기 칼날팁(120)의 회전방향에서 살펴볼 때 전면에는 유선형으로 형성된 칩배출부(123)이 형성된다. A chip discharging part 123 formed in a streamlined shape is formed on the front surface when viewed from the rotating direction of the blade tip 120.

상기 칼날팁(120)의 회전방향에서 살펴볼 때 측면으로 깎여진 경사부(122)가 형성된다. The sloped portion 122 is formed by side cutting when viewed from the rotating direction of the blade tip 120.

상기 경사부(122)는 회전하면서 칼날팁(120)이 폐문서의 단면에 최초 접촉할 때 점접촉할 수 있도록 일측으로 뾰족할 수 있도록 형성된다.The slope portion 122 is formed to be pointed to one side so that the blade tip 120 can be point-contacted when the blade tip 120 first contacts the end surface of the closed document.

본 발명의 다른 실시예로 형성된 절단칼날(150)은 칼날팁(120)의 개수가 적고 폭이 넓게 형성되는데, 각 칼날팁(120)에는 경사부(122)가 형성되고, 각각의 칼날팁(120)과 칼날팁(120)의 사이에는 널링홈(105)이 형성된다. The cutting blade 150 formed in another embodiment of the present invention has a small number of blade tips 120 and a wide width. Each blade tip 120 has an inclined portion 122, And a knurled groove 105 is formed between the blade tip 120 and the blade tip 120.

상기 널링홈(105)는 폐문서가 절단될 때 절단칼날(150)의 사이에서 미끌어지지 않도록 하기 위해서 형성된다.The knurled grooves 105 are formed so as not to slip between the cutting knives 150 when the closed documents are cut.

이하, 본 발명의 바람직한 실시예로 형성된 문서세단기용 절단칼날의 작동 및 작용을 설명하면 다음과 같다. Hereinafter, the operation and operation of the cutting blade for a document separator formed as a preferred embodiment of the present invention will be described.

문서세단기에 본 발명의 바람직한 실시예로 형성된 절단칼날(150)을 설치하고, 폐문서를 절단한다. A cutting blade 150 formed as a preferred embodiment of the present invention is installed in the document separator, and the closed document is cut.

폐문서를 투입하면 한 쌍의 커터축이 상호회전하여 절단칼날(150)의 절단팁(120)이 서로 마주보는 방향으로 회전한다. When a closed document is inserted, a pair of cutter shafts rotate with each other, and the cutting tips 120 of the cutting blade 150 rotate in directions opposite to each other.

서로 대응되는 절단칼날(150)의 사이에 폐문서가 인입되면, 절단팁(120)의 끝단이 정면으로 폐문서에 닿게 되는데, 이때, 경사부(122)를 제외한 뾰족한 부분부터 닿은 상태에서 경사부(122)의 일면을 따라서 폐문서가 찢어지게 된다. The distal end of the cutting tip 120 is brought into contact with the closed document at the front side. At this time, when the closed end of the cutting tip 120 touches the closed document except the inclined portion 122, The closed document is torn along one side of the paper 122.

즉, 절단팁(120)과 폐문서가 최초로 닿는 것이 점접촉으로 이루어지기 때문에 소음이 최소화된다.That is, since the first contact of the cutting tip 120 with the closed document is made by point contact, noise is minimized.

특히, 폐문서가 절단팁(120)에 의해서 뜯어지지 않고, 잘라지는 형태로 부드럽게 잘라지기 때문에 다수개의 절단칼날에 받는 부하를 모두 계산했을 때에는 모터에 가해지는 부하가 매우 적게 된다.In particular, since the closed document is not cut by the cutting tip 120 but smoothly cut in a cut form, the load applied to the motor becomes very small when the loads applied to the plurality of cutting blades are all calculated.

본 발명의 문서세단기용 절단칼날에 의하면 절단칼날이 상호 교차회전하면서 사이를 통과하는 폐문서를 절단할 때 절단칼날의 칼날팁의 끝단이 폐문서에 점접촉 한 후 경사면을 따라 연속하여 찢어지기 때문에 소음이 작고, 폐문서가 절단칼날의 칼날팁의 끝단에 점접촉하여 연속하여 찢어지기 때문에 모터의 부하를 줄여서 내구성이 증가하는 등의 효과가 발생한다.According to the cutting blade for a document separator according to the present invention, when cutting a closed document passing between the cutting blades while crossing each other, the end of the blade tip of the cutting blade is touched continuously along the inclined surface after making point contact with the closed document The noise is small and the closed document is torn continuously by point contact with the tip of the blade tip of the cutting blade so that the load of the motor is reduced and the durability is increased.

본 발명은 첨부된 도면을 참조하여 바람직한 실시예를 중심으로 기술되었지만 당업자라면 이러한 기재로부터 후술하는 특허청구범위에 의해 포괄되는 본 발명의 범주를 벗어남이 없이 다양한 변형이 가능하다는 것은 명백하다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention as defined by the appended claims.
