다단계식 문서세단기{MULTI STAGE TYPE PAPER SHREDDER}Multi-level document shredder {MULTI STAGE TYPE PAPER SHREDDER}

본 발명은 다단계식 문서세단기에 관한 것으로, 더욱 상세하게는 두껍고 파쇄하기 힘든 폐문서뭉치를 여러단계를 나누어서 절단할 수 있도록 다단계로 형성하고, 절단된 폐문서칩을 압축하여 자동으로 포장되도록 한 문서세단기에 관한 것이다. The present invention relates to a multi-stage document shredder, and more specifically, to form a thick and difficult to shred a bunch of waste documents divided into several stages to cut, multi-step document, the document to be automatically packed by compressing the cut waste paper chip It's about a sedan.

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 for finely cutting documents, transaction statements, and microfilm that require security in an office or a bank, or for finely cutting cardboard boxes or waste paper for recycling.

종래의 문서세단기는 도 3과 같이 상단에 문서투입구가 형성되고, 전방하단에 도어가 형성된 박스형상의 케이스(10)와; 상기 케이스(10)의 내부 상단에 다수개의 절단칼날(25)이 한 쌍의 커터축(23)에 고정되어 구동모터(28)에 의해 상호교차되면서 문서투입구(15)를 통해 인입되는 폐문서를 잘게 절단하는 절단장치(20)와; 상기 절단장치(20)의 하단에 형성되고 절단장치(20)에 의해 절단된 폐문서(이하, 폐문서칩이라 함)가 쌓이는 폐문서함(30)이 구성된다.The conventional document shredder has a box-shaped case 10 having a document inlet formed at an upper end thereof as shown in FIG. A plurality of cutting blades 25 are fixed to a pair of cutter shafts 23 on the inner upper end of the case 10 to cross closed by the driving motor 28, and the documents to be inserted through the document inlet 15 are opened. Cutting device 20 for cutting finely; The closed document box 30 is formed at the lower end of the cutting device 20 and accumulates the closed document (hereinafter referred to as a closed document chip) cut by the cutting device 20.

그러나, 상기 종래의 문서세단기는 다음과 같은 문제점이 있었다.However, the conventional document shredder has the following problems.

상기 문서투입대(100)는 폐문서뭉치(500)를 작업자가 직접 쌓아두고, 1차컨베이어(200)의 상단으로 밀어넣도록 형성된다. The document input table 100 is formed so that the operator stacks the waste document stack 500 directly, and pushed to the top of the primary conveyor (200).

상기 1차컨베이어(210)는 표면에 다수개의 돌기가 형성되어 1차세단기(300)의 상단에 형성된 투입구(305)의 상단으로 폐문서뭉치(500)가 이동한다.The primary conveyor 210 has a plurality of protrusions formed on the surface of the closed document stack 500 is moved to the top of the inlet 305 formed on the upper end of the primary shredder (300).

상기 1차세단기(300), 2차세단기(310) 및 최종세단기(400)에는 동일하게 투입구(305,315,405)가 각각 형성되는데, 상기 각각의 투입구(305,315,405)는 각각의 절단장치(306,316,406)의 상단에 유도되는 호퍼로 폐문서뭉치(500) 혹은 폐문서칩(510)이 투입되는 곳이다. Inlet 305, 315 and 405 are formed in the first and second breakers 310, 310 and 405, respectively, and the inlets 305, 315 and 405 are respectively formed on top of the respective cutting devices 306, 316 and 406. The waste paper bundle 500 or the waste paper chip 510 is introduced into the hopper to be guided.

상기 각각의 투입구(305,315,405)의 일측에서 경사져서 작업자가 호퍼의 내부를 관망할 수 있도록 각각 반사거울(307,317,407)이 형성되고, 센서(포토센서 또는 자기장센서)가 장착되어 호퍼가 폐문서뭉치(500) 혹은 폐문서칩(510)으로 가득찼을 경우에는 1,2,최종컨베이어(200,210,220)가 멈출 수 있도록 형성된다. Reflecting mirrors 307, 317, and 407 are formed to be inclined at one side of each of the inlets 305, 315, and 405 so that an operator can view the inside of the hopper, and a sensor (photo sensor or magnetic field sensor) is mounted so that the hopper is a closed document stack 500 ) Or when the document document 510 is full, the 1,2, the final conveyor (200, 210, 220) is formed to stop.

상기 각각의 절단장치(306,316,406)는 종래와 같이 절단칼날이 상호교차하도록 형성되어 모터에 의해 회전되면서 폐문서뭉치(500)를 절단할 수 있도록 형성되되, 1차세단기(300)의 절단장치(306)의 절단칼날의 정밀도(절단칼날의 폭과 날의 수)가 2차세단기(310)의 절단장치(316)의 절단칼날의 정밀도 보다 크고, 2차세단기(310)의 절단장치(316)의 절단칼날의 정밀도 보다 최종세단기(400)의 절단장 치(406)의 정밀도보다 크도록 형성된다. Each cutting device (306, 316, 406) is formed so that the cutting blades to cross each other as in the prior art is formed to cut the closed document stack 500 while being rotated by a motor, cutting device 306 of the primary shredder (300) Of the cutting device 316 of the secondary cutting machine 310 is larger than the precision of the cutting blade of the cutting device 316 of the secondary cutting machine 310. It is formed to be greater than the precision of the cutting device 406 of the final cutter 400 than the precision of the cutting blade.

상기 1,2차세단기(300,310) 이외에 최종세단기(400)의 사이에는 다수개의 세단기가 더 많이 설치될 수 있는데, 각각의 세단기는 컨베이어로 연결된다.In addition to the first and second terminators 300 and 310, a plurality of sewers may be installed between the final terminators 400, each of which is connected to a conveyor.

상기 최종세단기(400)의 하단에는 압축장치(450)가 형성되는데, 상기 압축장치(450)는 유압실린더(451)가 압축판(452)를 밀어서 최종세단기(400)의 하단에 쌓이는 폐문서칩(510)을 압축한다.A compression device 450 is formed at the lower end of the final shredder 400, wherein the compression device 450 is a hydraulic document stacking the hydraulic cylinder 451 by pushing the compression plate 452 at the bottom of the final shredder 400. 510 is compressed.

상기 압축장치(450)의 전방에 비닐봉투 등을 마련하여 폐문서칩뭉치를 배출한다. A plastic bag or the like is provided in front of the compression device 450 to discharge the waste paper chip bundle.

이하, 본 발명의 바람직한 실시예로 형성된 다단계식 문서세단기의 사용방법을 설명하면 다음과 같다. Hereinafter, a method of using the multi-stage document shredder formed by the preferred embodiment of the present invention will be described.

문서투입대(100)의 작업대(110)의 상단에 폐문서뭉치(500)를 올려놓고, 1차컨베이어(200)에 올려놓으면, 폐문서뭉치(500)가 1차컨베이어(200)를 따라 이송되다가 1차세단기(300)의 투입구(305)에 이르러 호퍼로 떨어진다.Put the waste document stack 500 on the top of the work table 110 of the document input table 100, and put it on the primary conveyor 200, the waste document stack 500 is transported along the primary conveyor 200 After reaching the inlet 305 of the primary separator 300, it falls into the hopper.

호퍼로 떨어진 폐문서뭉치(500)는 절단장치(306)에 의해서 절단되어 2차컨베이어(210)에 폐문서칩(510)으로 절단되어 떨어지게 되고, 상기 폐문서칩(510)은 2차컨베이어(210)를 따라서 2차세단기(310)의 투입구(315)에 이르러 호퍼로 떨어져서 절단장치(316)에 의해서 더욱 잘게 절단된다. The waste document bundle 500 dropped into the hopper is cut by the cutting device 306 to be cut off by the waste document chip 510 in the secondary conveyor 210, and the waste document chip 510 is separated from the secondary conveyor ( Along the 210, the inlet 315 of the secondary breaker 310 is dropped into the hopper and is more finely cut by the cutting device 316.

이러한 과정을 계속적으로 수행하여 원하는 크기의 폐문서칩(510)이 생기는 전단계에서 최종컨베이어(220)에 이르게 하고, 상기 최종컨베이어(220)에 떨어진 폐문서칩(510)은 최종세단기(400)의 절단장치(406)에 의해서 절단되어 공간부(455)에 떨어지게 된다 This process is continuously performed to reach the final conveyor 220 at the previous stage in which the waste paper chip 510 of the desired size is produced, and the waste paper chip 510 dropped to the final conveyor 220 is formed of the final shredder 400. It is cut by the cutting device 406 to fall to the space portion 455

상기와 같이 공간부(455)에 떨어진 폐문서칩(510)이 일정한 양 이상으로 쌓이게 되면, 압축판(452)이 유압실린더(451)에 의해서 일측으로 밀어서 압축한다. When the closed document chip 510 dropped to the space 455 as described above is stacked in a predetermined amount or more, the compression plate 452 is pushed to one side by the hydraulic cylinder 451 to compress.

상기 압축판(452)에 의해서 압출된 폐문서칩뭉치는 일정한 크기에 도달하면 일측으로 배출된다. The waste paper chip bundle extruded by the compression plate 452 is discharged to one side when reaching a predetermined size.
