Description

この発明は、新聞紙や雑誌等の古紙（ＮＰ）を用い、該古紙に含まれる繊維質を分断せずに、繊維の長手方向に沿って、古紙を細長に破砕する古紙破砕装置に関するものである。 The present invention relates to a used paper crushing device that uses used paper (NP) such as newspapers and magazines and crushes used paper into long and narrow pieces along the longitudinal direction of the fibers without dividing the fiber contained in the used paper. .

従来、プライバシーの保護や情報の漏洩防止の為に、使用されている古紙破砕機は、回転刃を使用して古紙を細断することが、一般的である。この場合、古紙は細片化することが可能であるが、繊維が短く切断されており、紙の強度低下を招いたり、製造段階で繊維の流出を招くため、再生紙の原料として利用されずに、そのまま焼却処分されることが多い。 Conventionally, in order to protect privacy and prevent information leakage, the used paper crusher is generally shredded using a rotary blade. In this case, the waste paper can be cut into small pieces, but the fibers are cut short, leading to a decrease in the strength of the paper, and outflow of the fibers in the manufacturing stage, so it is not used as a raw material for recycled paper. In many cases, they are incinerated.

そこで、上記問題を解決する為、紙中に含有する繊維質を分断せずに有効的に残す為、安全・安価で、誰もが簡単に効率良く、縦長形状に細断可能な古紙破砕装置を早期に開発することが望まれている。 Therefore, in order to solve the above problems, the fiber contained in the paper is effectively left without being cut, so it is safe and inexpensive, and anyone can easily and efficiently shred the paper into a vertically long shape. It is hoped that early development will be possible.

これまでに、出願されている古紙破砕装置に関する特許文献を参考のため、紹介する（特許文献１〜３参照）。

そして、ケース本体（１）の背面平板（１ｂ）の内面左上には、駆動軸側が後方側に突出するようにして駆動用電動モートル等の駆動手段（ＭＯ）を軸着して設け、且つ、駆動軸部には、二列歯付スプロケット（４ｄ）を嵌着して設け、且つ、該ケース本体（１）の下方左右には、ローラー・チェーン（９）（１０）で従動連結した従動軸部（３ａ）（３ｃ），（３ａ）（３ｃ）をそれぞれ軸着し、該従動軸部（３ａ）（３ｃ）は前面平板（１ａ）と背面平板（１ｂ）の表面側に螺着した軸受部（２）（２），（２）（２）にそれぞれ嵌挿して設けられている。 And, on the upper left of the inner surface of the back plate (1b) of the case body (1), driving means (MO) such as an electric motor for driving is pivotally mounted so that the driving shaft side protrudes rearward, and The drive shaft is provided with a double-row toothed sprocket (4d) fitted therein, and a driven shaft that is driven by a roller chain (9) (10) on the lower left and right sides of the case body (1). Bearings in which the parts (3a) (3c), (3a) and (3c) are axially attached, and the driven shaft parts (3a) and (3c) are screwed to the surface side of the front flat plate (1a) and the rear flat plate (1b). The parts (2), (2), (2) and (2) are respectively inserted and provided.

又、図２・図３に示すように、ケース本体（１）の左右両端部の前後水平方向には６枚の連接回転刃（７）を従動軸部（３ｃ）にそれぞれ軸着し、駆動軸（ＭＯ'）と従動軸（３ａ）をそれぞれ連結するローラー・チェーン（９）（１０）の外側に外接させて、従動軸（３ａ）の回転方向（下向き方向）と反対方向（上向き方向）に回転するように軸支されている。 As shown in FIGS. 2 and 3, six articulated rotating blades (7) are respectively attached to the driven shaft portion (3c) in the front-rear horizontal direction of the left and right ends of the case body (1) and driven. The outer side of the roller chain (9) (10) connecting the shaft (MO ') and the driven shaft (3a) is circumscribed, and the direction opposite to the rotational direction (downward direction) of the driven shaft (3a) (upward direction) It is pivotally supported so as to rotate.

又、図５・図６に示すように、ケース本体（１）の下方部に位置し、且つ、左右水平方向に、所定間隔（Ｐ）で前後方向に刃付チェーン（１２）を七列並設して設け、該刃付チェーンの回転方向は、前面側から上向き・下向きの順に、交互に回転するように構成されている。そして、刃付チェーン（１２）の下方中央には、アジャスター（８ａ）と、スプリング（８ｂ）と、ワッシャー（８ｃ）と、ナット（８ｄ）を組み合せたチェーン張り調整装置（８）をそれぞれ設けている。そして、更に、刃付チェーン（１２）の上部下面と、下部上面を、１４枚の刃付チェーンガイド（１８）（１９）でガイドして、刃付チェーン（１２）が円滑に回転するよう配慮されている。 Further, as shown in FIGS. 5 and 6, seven chains of blades (12) are located in the lower part of the case body (1) and arranged in the front-rear direction at a predetermined interval (P) in the left-right horizontal direction.

First, used paper (NP) is introduced in a horizontal direction from a used paper inlet (1a ′) provided on the front surface of the case body (1), and a pressing device ( Set between Y) and bladed chain (12). When the power button is pressed, the driving electric motor (MO) is activated, the bladed chain (12) and the articulated rotary blade (7) rotate, and at the same time the inner case traction device of the pressing device (Y) is released. The force of the spring (13) in the pressing device (Y) works downward, and the set used paper (NP) is pressed downward and pressed against the chain (12) with blades to start crushing. At the same time, the connected rotary blades (7) provided at the left and right ends rotate in the center direction of the apparatus, so that the thick portions of the creases at both ends of the used paper are crushed. And while the crushing device is moving, in order to prevent the crushed waste paper (NP) from wrapping around the articulated rotary blade (7), the electric control device (X) rotates the driving electric motor (MO). Is configured to rotate alternately forward and reverse periodically. Then, the crushed waste paper (NP) is discharged downward from the lower part of the articulated rotary blades (7) at both the left and right ends, the crushing of a certain amount of waste paper is finished, and the inner case (14) of the pressing device (Y) ) When the tip reaches near the upper surface of the bladed chain (12), the limit switch (LS) is actuated to stop the driving electric motor (MO), and the bladed chain (12) and the articulated rotary blade (7 ) Respectively stop rotating, and at the same time, the inner case traction device of the pressing device (Y) is operated to raise the inner case (14) and stop at the top.
