が望まれる。(Prior Art) A shredder is provided for shredding documents to prevent leakage of confidential information at companies, etc., but there are cases where a shredder is required even in an ordinary household or a self-employed business. Therefore, it is desired that the shredder be as small as possible and take up less installation space.
従来のシュレッダのカッター装置（カッタ刃）は、第９

６同志を重ね合せて回転接触させている。The conventional shredder cutter device (cutter blade)
As shown in the figure, a large number of rotary blades 1 form an edge 17.
6, and the rotary blades 1 are arranged so that their edges 17 slide together.
Six comrades are stacked on top of each other and rotated into contact.
そして紙の細断は、第１０図に示すように回転刃１６を
矢印Ａ方向に回転して紙１８を噛み込捷せて細断する。Then, the paper is shredded by rotating the rotary blade 16 in the direction of arrow A to bite and twist the paper 18 as shown in FIG. 10.
すなわち、差し込筐れた紙１８の引き込み力は回転刃１
６の外周１９同志が交るイの部分によって与えられると
同時にエッチ１７の摺シ合せ部で紙は剪断力によシ細断
される。In other words, the pulling force of the inserted paper 18 is the same as that of the rotary blade 1.
The paper is shredded by shearing force applied by the portion A where the outer peripheries 19 of 6 intersect, and at the same time at the sliding seam portion of the etch 17.

という問題がある。(Problem to be Solved by the Invention) The conventional shredder cutter device described above shreds paper using the shearing force generated by sliding the workpieces 17 together, so it requires a considerably large shearing force to shred the paper. requires a rotary blade 16
Since it takes a large amount of torque to rotate the shredder, there are problems in that the drive device is large and the shredder itself becomes large.
本発明は、細断の方式を従来の剪断方式に代えて紙を刃

体の周速度よ）も速くしたものである。(Means for Solving the Problems) A means according to the present invention for solving the above problems is to provide a large number of rotary blades with blades at the tips of the outer circumferential parts, and to insert a shaft into the center of the rotary blades to form a laminated body. A cylindrical body provided with a large number of annular grooves is provided, and the tip of the outer periphery of the laminated and integrated rotary blade is inserted into the annular groove of the cylindrical body, so that the cylindrical body and the laminated and integrated rotary blade can be rotated. The circumferential speed of the rotary blade is also faster than that of the cylindrical body.

で切断される。(Function) With this structure, the inserted paper is placed between the annular grooves along the outer circumferential surface of the cylindrical body, and the paper that is inserted into the annular groove is placed between the annular grooves. Since the central part of the cylinder is pressed with a rotating blade, the paper is pressed against the outer circumferential surface of the cylinder. This pressing force causes the paper to be pulled in. Also, the paper is passed through the annular groove of the cylindrical body, and the central part is pushed by the rotating blade, so the pressing of the adjacent rotating blades is done by force, and the paper is stretched between the annular grooves. Become. The paper stretched in the annular groove is then cut by a rotating blade.

細断と引き込みとが有機的に関連して、紙は効率よ〈細
断される。By making the circumferential speed of the rotary blade faster than the circumferential speed of the cylindrical body, a frictional force is generated between the paper and the outer circumferential surface of the cylindrical body in the paper drawing direction, and the rotary blade pulls the paper. At the moment of shredding, it is the same as if the paper were stretched between the annular grooves and fixed in the drawing direction. As a result, paper shredding and drawing are organically related, and paper is efficiently shredded.
（実施例） 以下本発明の一実施例について詳Ｍｉに説明する。(Example) An embodiment of the present invention will be described in detail below.

じ部１０にナタト１１を螺合して締め付けることにより
行なわれる。In FIG. 1, rotary blades 8 made of thin steel plates are stacked with spacers 9 in between. In this embodiment, as shown in FIG.
This is done by inserting the spacer 9 alternately, positioning the spacer 9 at the end of the stack, and screwing the nut 11 into the threaded part 10 and tightening it.

又は７ランジの役目を１−１細断された紙の曲シを拘束
する。The operation of this embodiment configured in this way will be explained next. Paper p#-i inserted into the paper insertion slot 3, the cylindrical body 15 first
, and then the cutting edge of the rotary blade 8 to begin cutting and retraction. This state occurs at position A in FIG. 6, and when cutting starts, the cut end P' of the cut paper is cut into a circular shape by the rotary blade 8, as shown in FIGS. 5 and 6. It is bent into the groove 12 and is pressed against both sides of the rotary blade 8 due to the elasticity of the paper, and at the same time is pressed against the outer peripheral surface of the cylindrical body 13. Since the circumferential speed vlFi of the rotary blade 8 is faster than the circumferential speed v2 of the cylindrical body, the cut end i of the cut paper is pressed against both sides of the rotary blade 8 = the outer peripheral surface of the cylindrical body 13 while being squeezed downward. 150 rotations of the cylindrical body which rotates a little later than the rotary blade 8 generates a retraction force and is retracted. Further, the cut end of the cut paper is bent into the annular groove 12 by the rotary blade 8, so that the cut end P' is a kind of rib or 7 of the shredded paper, as shown in FIG. The role of the lunge is to restrain the bent sheet of shredded paper.
これによう細断された紙は曲ることなく伸びた状態で、
回転刃８と円柱体１３との間を通過し廃山される。The paper shredded like this is stretched without bending,
It passes between the rotary blade 8 and the cylindrical body 13 and is discarded.
一方回転刃８による切断は、円柱体１３の環状溝１２に
掛は渡された紙の中央を、相隣接する回転刃８で押すの
で、円柱体１３の外周面に紙を押し付けるようにして紙
を環状溝１２に張ることになる。On the other hand, when cutting with the rotary blade 8, the center of the paper passed through the annular groove 12 of the cylindrical body 13 is pushed by the adjacent rotary blades 8, so the paper is pressed against the outer peripheral surface of the cylindrical body 13. is applied to the annular groove 12.
そして、このように環状溝１２に張られた中央を回転刃
８で切断するので、紙の細断は効率よく行なわれる。そ
してこの細断は、従来のような剪断力による細断ではな
く、回転刃８による切断であるので、細断に要するトル
クは小さくなる。Since the rotary blade 8 cuts the center of the annular groove 12 in this way, the paper can be efficiently shredded. Since this shredding is not done by shearing force as in the conventional art, but by the rotary blade 8, the torque required for shredding is reduced.
又、円柱体１３は、紙の細断には全く関係しないので、
半永久的に取替えなくてもよい。そして、積層した回転
刃８を取シ替えることも可能である。Moreover, since the cylindrical body 13 is not involved in shredding paper at all,
There is no need to replace it semi-permanently. It is also possible to replace the stacked rotary blades 8.
第７図には回転刃の他の実施例を示す。この回転刃８′
は、スペーサを用いないで積層し、かつ刃先２０は、三
角形状になっている。FIG. 7 shows another embodiment of the rotary blade. This rotating blade 8'
are laminated without using a spacer, and the cutting edge 20 has a triangular shape.
この回転刃８′によるときも同様に、切断端ｙは回転刃
８′によシ環状溝１２側に曲げられる。Similarly, when the rotary blade 8' is used, the cut end y is bent toward the annular groove 12 by the rotary blade 8'.
そして曲げられた切断端Ｐ′は、刃先２０の側面２１と
弾性体で作られた円柱体１３０角部とで挾持され、強い
引き込み力が生ずる。そして、刃先２０の周速度を切断
端ｙの挟持部周速度と円柱体１３０周速度とが略等しく
なるように選択することによシ、細断された紙の引き込
み力に要する回転トルクは最小限になる。Then, the bent cut end P' is held between the side surface 21 of the cutting edge 20 and the corner of the cylindrical body 130 made of an elastic body, and a strong retracting force is generated. By selecting the circumferential speed of the cutting edge 20 so that the circumferential speed of the clamping part of the cutting end y and the circumferential speed of the cylindrical body 130 are approximately equal, the rotational torque required to pull in the shredded paper is minimized. limited.
その他の作用については、先に説明した実施例と同じで
あるので、ここでの説明は省略する。Other functions are the same as those in the previously described embodiment, so their explanation will be omitted here.

I decided to shred the paper, so
Compared to conventional shredding using shearing force, the torque of the rotary blade required for paper shredding can be significantly reduced, and the pulling force of the shredded paper is sufficient to reduce the torque of the rotary blade with low rotational torque. use, and the drive device can be downsized.
