Abstract

The present invention relates to a uniform cutting type cutting device for a document shredder, and more specifically, to a uniform cutting type cutting device for a document shredder, which forms the position of a cutting blade tip of a cutting blade formed in the cutting device in a W arrangement or a zigzag arrangement, so that waste documents can be inserted while simultaneously being torn all over the place, thereby significantly reducing the noise as well as reducing the load on a motor. According to the uniform cutting type cutting device for a document shredder formed as a preferred embodiment of the present invention, since the position of the cutting blade tip of the cutting blade is arranged in a W shape or a zigzag shape in the axial direction, incoming waste documents are cut sequentially over the entire surface. Therefore, in addition to reducing noise, the waste documents are not concentrated, so that the load is not added to the motor. Since the waste documents are not cut while being pushed to one side, the force applied to a cutting blade shaft is uniformly exerted. Thus, the cutting blade shaft does not bend. A paper guide is formed where the last cutting blade of the cutting blade shaft is formed to prevent waste document chips from intervening so that no load on the motor is generated. Since the waste documents are cut entirely or symmetrically from the bottom thereof, the waste documents are not skewed to one side, uncut parts are not generated, and thus security is achieved.

본 발명은 문서세단기용 균일절단방식 절단장치에 관한 것으로, 더욱 상세하게는 절단장치에 형성되는 절단칼날의 절단칼날팁의 위치를 W배열 또는 지그재그배열로 형성하여 폐문서가 투입될 때 전면적으로 동시에 찢어지면서 투입될 수 있도록 하여 모터에 부하를 줄일 수 있을 뿐만 아니라 소음도 현저히 줄일 수 있는 문서세단기용 균일절단방식 절단장치에 관한 것이다.The present invention relates to a uniform cutting-type cutting device for a document shredder, and more specifically, the position of the cutting blade tip of the cutting blade formed in the cutting device is formed in a W arrangement or a zigzag arrangement, and when the waste document is input, it is simultaneously The present invention relates to a uniform cutting method cutting device for a document shredder that can reduce the load on the motor and significantly reduce noise by allowing it to be input while being torn.

문서세단기는 사무실이나 은행 등에서 보안을 요하는 문서나 거래명세서 및 마이크로 필름 등을 잘게 절단하거나, 골판지 박스나 폐지 등의 재활용을 목적으로 잘게 절단하는 기기를 말한다.A document shredder is a device that finely cuts documents, transaction statements, micro films, etc. that require security in an office or bank, or finely cuts them for recycling such as cardboard boxes or waste paper.

종래의 문서세단기는 상단에 문서투입구가 형성되고, 전방하단에 도어가 형성된 박스형상의 본체와; 상기 본체의 내부 상단에 다수개의 절단칼날이 한 쌍의 절단칼날축에 고정되어 구동모터에 의해 상호교차되면서 문서투입구를 통해 인입되는 폐문서를 잘게 절단하는 절단장치와; 상기 절단장치의 하단에 형성되고 절단장치에 의해 절단된 폐문서(이하, 폐문서칩이라 함)가 쌓이는 폐문서함이 구성된다.Conventional document shredder is a document-shaped opening is formed at the top, and a box-shaped body having a door at the bottom of the front; A cutting device for finely cutting a waste document input through a document inlet while a plurality of cutting blades are fixed to a pair of cutting blade shafts at the top of the inside of the main body and cross each other by a driving motor; A waste document box is formed at the bottom of the cutting device and stacks waste documents (hereinafter referred to as waste document chips) cut by the cutting device.

상기 문서세단기의 절단장치에는 한 쌍의 축이 서로 대응하여 회전할 수 있도록 동력전달구가 형성되는데, 상기 동력전달구는 일반적으로 맞물려서 회전할 수 있는 기어로 형성되고, 일측의 기어에는 스프로켓이나 또 다른 기어가 형성되어 체인 등을 통해서 모터로부터 공급되는 동력을 전달받는다.In the cutting device of the document shredder, a power transmission port is formed so that a pair of axes can rotate in correspondence with each other, and the power transmission port is generally formed of a gear that can be engaged and rotated, and a sprocket or another on one side of the gear. Gears are formed to receive power supplied from the motor through a chain or the like.

상기 절단장치의 한 쌍의 절단칼날축에는 다수개의 절단칼날과 절단칼날가이드가 번갈아가면서 결합되어, 절단칼날축의 각각의 절단칼날이 서로 상호교차회전 할 수 있도록 즉, 하나의 절단칼날축의 절단칼날은 다른 절단칼날축의 절단칼날가이드와 대응하도록 형성되어 절단칼날끼리는 서로 상호교차회전 할 수 있도록 형성된다.A plurality of cutting blades and a cutting blade guide are alternately coupled to a pair of cutting blade shafts of the cutting device so that the cutting blades of the cutting blade shafts can alternately rotate with each other, that is, the cutting blades of one cutting blade shaft It is formed to correspond to the cutting blade guides of different cutting blade shafts so that the cutting blades can rotate with each other.

도 1은 종래의 절단칼날(20)과 절단칼날축(10) 및 절단칼날가이드(30)의 설치 단면도를 나타낸 것으로, 절단칼날가이드(30)를 고정하는 절단칼날가이드축(40)이 형성된다.1 shows a conventional cross-sectional view of the cutting blade 20, the cutting blade shaft 10 and the cutting blade guide 30, the cutting blade guide shaft 40 for fixing the cutting blade guide 30 is formed .

이러한 문서세단기의 절단장치에 관한 기술은 대한민국 등록실용신안공보 제0370537호에 개시된 바 있다. A technique for cutting the document shredder has been disclosed in Korean Registered Utility Model Publication No. 0370537.

그러나, 종래의 문서세단기용 절단장치는 다음과 같은 문제점이 있었다. However, the conventional cutting device for a document shredder has the following problems.

(1) 절단칼날의 절단칼날팁의 위치 설정이 축방향으로 가운데로 몰리는 'V'자 형태 또는 일방향 나선형으로 형성되어 폐문서가 인입될 때 절단칼날팁이 폐문서를 한쪽으로 이동시키면서 절단, 즉 폐문서가 절단되면서 절단칼날팁의 위치가 이동함에 따라서 이동하기 때문에 결국 한쪽으로 몰려서 절단되어 모터에 부하가 많이 걸린다. (1) When the position of the cutting blade tip of the cutting blade is formed in a'V' shape or unidirectional spiral driven toward the center in the axial direction, the cutting blade tip moves the waste document to one side while cutting, i.e. As the position of the cutting blade tip moves as the waste document is cut, it is eventually swung to one side and severely loaded on the motor.

(2) 폐문서가 한쪽으로 밀리면서 절단되어 절단칼날축이 바깥방향으로 밀려나면서 휘는 현상이 발생한다. (2) The waste document is cut while being pushed to one side, and the cutting blade shaft is pushed outward, resulting in bending.

(3) 절단칼날축의 마지막 절단칼날이 형성된 곳 쪽으로 폐문서칩이 모이게 되어 폐문서칩이 축의 끝단에 쌓이게 되므로 이것이 마찰을 증가시켜 모터의 부하를 증가시킨다.(3) Since the waste document chip accumulates toward the end of the cutting blade shaft, the waste document chip accumulates at the end of the shaft, which increases friction and increases the motor load.

(4) (2)번과 같이 폐문서가 축의 끝단으로 이동되어 절단되면, 폐문서의 일부분이 미절단되는 현상이 발생하여 보안상 위험하다.(4) When the closed document is moved to the end of the shaft and cut as shown in (2), a part of the closed document is uncut, which is dangerous for security.

상기한 문제점을 해결하기 위해서, 본 발명은 좌우측면판이 형성되고, 좌우측면판의 가운데를 가로지르는 격판이 형성되는 몸체와; 상기 몸체의 격판의 후방에 부착되는 모터; 상기 격판의 전방에 형성되고, 좌,우측면판을 가로질러서 삽입되는 한 쌍의 절단칼날축이 형성되며, 상기 각 절단칼날축에는 다수개의 절단칼날과 절단칼날가이드가 번갈아가면서 삽입되어 각 절단칼날축의 절단칼날이 상호교차회전할 수 있도록 형성되는 칼날부와;In order to solve the above problems, the present invention is a left and right side plate is formed, the body is formed with a plate across the center of the left and right side plate; A motor attached to the rear of the plate of the body; A pair of cutting blade shafts formed on the front side of the plate and inserted across the left and right side plates are formed, and a plurality of cutting blades and cutting blade guides are alternately inserted into each cutting blade shaft so that each cutting blade shaft A cutting edge portion formed so that the cutting blades can cross each other;

상기 우측면판의 측면에 형성되고, 모터와 각 절단칼날축을 상호 대향하게 회전할 수 있도록 형성되는 동력전달구로 구성되는 일반적인 문서세단기용 절단장치에 있어서,In the cutting device for a general document shredder, which is formed on the side of the right side plate, and is composed of a power transmission tool formed to rotate the motor and each cutting blade shaft to face each other,

상기 절단칼날은 육각형태의 축삽입홀이 형성되고, 상기 축삽입홀에는 반원형상의 인디케이터공간부가 형성되되,The cutting blade has a hexagonal shaft insertion hole, and the shaft insertion hole is formed with a semi-circular indicator space.

상기 절단칼날은 절단칼날팁의 위치를 연속되는 절단칼날의 절단칼날팁의 위치를 회전방향으로 조금씩 회전시켜 배치하여, 축방향으로 절단칼날팁이 'W'자 또는 지그재그 형태로 배열되도록 형성된다.The cutting blade is formed by rotating the position of the cutting blade tip by rotating the position of the cutting blade tip of the continuous cutting blade little by little in the rotational direction, so that the cutting blade tip is arranged in the form of'W' or zigzag in the axial direction.

본 발명에서 균일절단방식이라 함은 절단칼날팁의 배치가 폐문서가 절단되는 위치가 좌,우측이 균일하게 절단되도록 형성된다는 의미이다.In the present invention, the uniform cutting method means that the arrangement of the cutting blade tip is formed so that the left and right positions of the waste document are cut uniformly.

본 발명의 바람직한 실시예로 형성된 문서세단기용 균일절단방식 절단장치에 의하면 다음과 같은 효과가 발생한다.According to the uniform cutting method cutting device for a document shredder formed in a preferred embodiment of the present invention has the following effects.

(1) 절단칼날의 절단칼날팁의 위치 설정이 축방향으로 'W'자 형상 또는 지그재그형상으로 배치되기 때문에 인입되는 폐문서의 전면에 걸쳐서 차례로 절단되기 때문에 소음이 줄어들뿐만 아니라 몰리지 않기 때문에 모터에 부하가 가중되지 않는다.(1) Since the positioning of the cutting blade tip of the cutting blade is arranged in a'W' shape or a zigzag shape in the axial direction, it is cut in turn over the entire front of the incoming document, so noise is not only reduced, but also does not drive the motor. No load is applied.

(2) 폐문서가 한쪽으로 밀리면서 절단되지 않기 때문에 절단칼날축에 가해지는 힘이 균일하게 미쳐서 절단칼날축이 휘는 현상이 발생하지 않는다.(2) Since the waste document is not cut while being pushed to one side, the force applied to the cutting blade shaft is uniformly insane, so that the cutting blade shaft does not bend.

(3) 절단칼날축의 마지막 절단칼날이 형성된 곳에 종이가이드가 형성되어 폐문서칩이 끼어들지 못하도록 하여 모터의 부하를 발생하지 않는다.(3) A paper guide is formed where the last cutting edge of the cutting blade shaft is formed, so that the waste document chip is not inserted, so that the motor load is not generated.

(4) 폐문서의 하단부터 전체적 또는 대칭적으로 균일하게 절단되므로 한쪽으로 치우쳐지지 않아서 미절단부분이 발생하지 않아서 철저한 보안이 이루어진다.(4) Since the entire document is cut evenly or symmetrically from the bottom of the waste document, it is not biased to one side, so that an uncut portion does not occur, thus ensuring thorough security.

상기 격판(101c)의 전방에 형성되고, 좌,우측면판(101a,101b)을 가로질러서 삽입되는 한 쌍의 절단칼날축(150)이 형성되며, 상기 각 절단칼날축(150)에는 다수개의 절단칼날(120)과 절단칼날가이드(130)가 번갈아가면서 삽입되어 각 절단칼날축(150)의 절단칼날(120)이 상호교차회전할 수 있도록 형성되는 칼날부(112)와;A pair of cutting blade shafts 150 formed on the front of the plate 101c and inserted across the left and right side plates 101a and 101b are formed, and each cutting blade shaft 150 has a plurality of cuts. A blade unit 112 and a cutting blade guide 130, which are alternately inserted and formed so that the cutting blades 120 of each cutting blade shaft 150 can rotate with each other;

상기 우측면판(101b)의 측면에 형성되고, 모터(111)와 각 절단칼날축(150)을 상호 대향하게 회전할 수 있도록 형성되는 동력전달구(115)로 구성되는 일반적인 문서세단기용 절단장치(100)에 있어서,A cutting device for a general document shredder formed on a side surface of the right side plate 101b and composed of a power transmission port 115 formed to rotate the motor 111 and each cutting blade shaft 150 to face each other ( In 100),

상기 절단칼날(120)은 육각형태의 축삽입홀(123)이 형성되고, 상기 축삽입홀(123)에는 반원형상의 인디케이터공간부(125)가 형성되되,The cutting blade 120 has a hexagonal shaft insertion hole 123 is formed, the shaft insertion hole 123 is formed with a semi-circular indicator space portion 125,

상기 절단칼날(120)은 절단칼날팁(121)의 위치를 연속되는 절단칼날(120)의 절단칼날팁(121)의 위치를 회전방향으로 조금씩 회전시켜 배치하여, 절단칼날(120)이 교차하는 부분을 기준으로 'W'자 또는 지그재그 형태로 배열되도록 형성된다.The cutting blade 120 is arranged by rotating the position of the cutting blade tip 121 of the cutting blade 120 in the rotation direction little by little by rotating the position of the cutting blade tip 121, so that the cutting blade 120 intersects It is formed to be arranged in a'W' shape or a zigzag form based on the part.

상기 몸체(101)의 좌,우측면판(101a, 101b)에는 문서세단기의 내부 상단에 고정되도록 다수개의 플랜지가 형성된다. A plurality of flanges are formed on the left and right side plates 101a and 101b of the body 101 so as to be fixed to the inner top of the document shredder.

상기 칼날부(112)에는 한 쌍의 절단칼날축(150)이 나란하게 형성되는데, 좌우측면판(101a, 101b)의 내측면과 만나는 부분에는 각각 가이드링(108)이 형성되고, 상기 가이드링(108)의 상부에 종이가이드(180)가 고정된다. A pair of cutting blade shafts 150 are formed side by side in the blade part 112, and guide rings 108 are formed at portions of the left and right side plates 101a and 101b, respectively, and the guide rings ( 108) the paper guide 180 is fixed on the top.

상기 종이가이드(180)는 하단에 쐐기형상의 가이드링안착부(181)가 형성되고, 상단으로 돌출되어 좌측면판(101a) 또는 우측면판(101b)의 상단까지 돌출되는 돌출몸체(182)가 형성되며, 상기 돌출몸체(182)는 좌측면판(101a) 또는 우측면판(101b)에 고정된다.The paper guide 180 is formed with a wedge-shaped guide ring seating portion 181 at the bottom, and a protruding body 182 protruding to the top and protruding to the top of the left side plate 101a or the right side plate 101b is formed. The protruding body 182 is fixed to the left side plate 101a or the right side plate 101b.

상기 칼날부(112)에는 각 절단칼날축(150)에 절단칼날(120)과 절단칼날가이드(130)가 번갈아가면서 삽입된다. The cutting part 120 and the cutting blade guide 130 are alternately inserted into the cutting part 112 in each cutting blade shaft 150.

상기 절단칼날(120)은 육각형태의 축삽입홀(123)이 형성되고, 상기 축삽입홀(123)에는 반원형상의 인디케이터공간부(125)가 형성된다. The cutting blade 120 is formed with a hexagonal shaft insertion hole 123, and a semi-circular indicator space 125 is formed in the shaft insertion hole 123.

상기 절단칼날(120)과 인접하는 절단칼날(120)을 삽입할 때 인디케이터공간부(125)를 확인하면서 절단칼날팁(121)의 회전방향으로의 위치를 잡을 수 있다. When inserting the cutting blade 120 adjacent to the cutting blade 120, while checking the indicator space 125, the cutting blade tip 121 can be positioned in the rotational direction.

즉, 회전방향으로 절단칼날팁(121)은 종이를 절단하도록 형성되는데, 회전하는 방향으로 절단칼날팁(121)의 끝단의 위치가 도 4의 A,B와 축방향으로 배열될 수 있다.That is, the cutting blade tip 121 in the rotation direction is formed to cut the paper, the position of the end of the cutting blade tip 121 in the rotating direction may be arranged in the axial direction with A, B of FIG. 4.

상기와 같이 절단칼날팁(121)은 폐문서가 인입될 때 가로로 절단하는 부분이고, 절단칼날(120)의 폭방향은 세로로 절단하는 부분이므로, 가로로 절단하는 부분의 끝단이 골고루 퍼져 있을 경우에 폐문서가 투입되면 균일하게 절단될 수 있다.As described above, the cutting blade tip 121 is a part that is cut horizontally when a waste document is received, and the width direction of the cutting blade 120 is a part that is cut vertically, so that the ends of the cut parts are spread evenly. In this case, if the waste document is input, it can be cut evenly.

즉, 종래의 절단칼날팁(121)의 배치는 도 4와 같이 'V'자 형태로 배치되거나, 빗금형태로 배치되었는데, 'V'자 형상으로 배치되면 폐문서가 절단되면서 가운데로 모이게 되고, 빅금형태로 배치되면 폐문서가 절단되면서 일방향으로 밀리게 되어 모터에 부하가 많이 걸리게 된다.That is, the arrangement of the conventional cutting blade tip 121 is arranged in a'V' shape as shown in FIG. 4 or is arranged in a hatched shape. When disposed in a'V' shape, the waste documents are cut and gathered in the middle, When placed in the form of a big gold, the waste documents are cut and pushed in one direction, which puts a lot of load on the motor.

상기 절단칼날(120)은 절단칼날팁(121)의 위치를 연속되는 절단칼날팁(121)의 위치를 회전방향으로 다르게 배치하여, 축방향으로 절단칼날팁(121)이 'W'자 또는 지그재그 형태로 배열되도록 형성된다.In the cutting blade 120, the position of the cutting blade tip 121 is continuously arranged differently in the rotational direction, so that the cutting blade tip 121 is'W' or zigzag in the axial direction. It is formed to be arranged in a shape.

본 발명의 바람직한 실시예로 형성된 문서세단기용 균일절단방식 절단장치에 의하면 절단칼날의 절단칼날팁의 위치 설정이 축방향으로 'W'자 형상 또는 지그재그형상으로 배치되기 때문에 인입되는 폐문서의 전면에 걸쳐서 차례로 절단되기 때문에 소음이 줄어들뿐만 아니라 몰리지 않기 때문에 모터에 부하가 가중되지 않고, 폐문서가 한쪽으로 밀리면서 절단되지 않기 때문에 절단칼날축에 가해지는 힘이 균일하게 미쳐서 절단칼날축이 휘는 현상이 발생하지 않으며, 절단칼날축의 마지막 절단칼날이 형성된 곳에 종이가이드가 형성되어 폐문서칩이 끼어들지 못하도록 하여 모터의 부하를 발생하지 않고, 폐문서의 하단부터 전체적 또는 대칭적으로 균일하게 절단되므로 한쪽으로 치우쳐지지 않아서 미절단부분이 발생하지 않아서 철저한 보안이 이루어진다.According to a uniform cutting method cutting device for a document shredder formed in a preferred embodiment of the present invention, since the positioning of the cutting blade tip of the cutting blade is arranged in an ``W'' shape or a zigzag shape in the axial direction, it is placed on the front of the incoming document. Since it is cut sequentially, the noise is not only reduced, but the load is not applied to the motor because it is not driven, and the force applied to the cutting blade axis is uniformly insane because the waste document is not cut while being pushed to one side. It does not occur, and the paper guide is formed where the last cutting edge of the cutting blade shaft is formed, so that the waste document chip does not get in and does not generate a load on the motor. Because it is not skewed, the uncut part does not occur, so thorough security is achieved.
