Description

本発明は、例えば包装覆いの紙やビニールシートの取り去り、及び、雑誌、新聞等の切り抜きや切断等を行う際に、カッター刃先の微細突出量変更を容易で安全に行なう紙切カッターに関する。 The present invention relates to a paper cutting cutter that can easily and safely change a fine protrusion amount of a cutter blade edge when, for example, removing a paper or vinyl sheet for packaging and cutting or cutting a magazine or a newspaper.

従来の刃先突出量を変更するカッターでは、ケース体から外方に直接刃先を伸縮調節する形態が多く、変更調節量が大雑把であり、また、非使用時にはカッター刃先が外方に突出したままで、安全上に問題が残っていた。 In conventional cutters that change the protrusion amount of the blade edge, there are many forms in which the blade edge is extended and retracted directly from the case body, the change adjustment amount is rough, and the cutter blade edge protrudes outward when not in use. There were still safety issues.

実開昭６０−１７９２８０号公報Japanese Utility Model Publication No. 60-179280 特開平１０−９４６８３号公報Japanese Patent Laid-Open No. 10-94683 特開平１０−１５６０６１号公報Japanese Patent Laid-Open No. 10-156061

特許文献１に示す技術は、刃先突出量を変更するのに、止めネジ（１０）を緩めて長孔（３）に沿って動かしネジ固定すると、刃先の突出量が変わるものであるが、刃先が常時外方に突出したままとなり、安全上問題を生じている。
特許文献２に示す技術においては、本発明との具体的構成内容差については後に詳述するが、刃体を収納する取付体（３）を、操作体（６）の楔片（３６）で直接的に強制押圧して取付体（３）を変形させ、刃先（３１）部を本体（２）から外方に飛び出させる事で、被切断物を切断するものである。 In the technique shown in Patent Document 1, the amount of protrusion of the blade edge is changed by loosening the set screw (10), moving along the elongated hole (3) and fixing the screw by changing the blade edge protrusion amount. Always protrudes outward, causing a safety problem.
In the technique shown in Patent Document 2, a specific configuration content difference from the present invention will be described in detail later, but the attachment body (3) for housing the blade body is a wedge piece (36) of the operation body (6). The object to be cut is cut by forcibly pressing it directly to deform the attachment body (3) and let the blade edge (31) part jump out of the main body (2).

この特許文献２でも、操作体（６）の楔片（３６）位置をそのままにしておくと、刃先（３１）は常時外方に突出したままであり、やはり安全上の問題を生じている。
特許文献３に示す技術は、特許文献１や特許文献２に示した、非使用時の刃先安全上の欠点を改良するものであった。
それは、切断刃の外周囲に本体押圧で弾性移動する押圧弾片なる保護具を設け、非使用時には刃物の突出を防止して安全性を向上し、使用時には刃先部を相手に押し付けることで、押圧弾片が凹んで逃げ、それに伴なって刃物が押し出され相手を切断すると言うものである。 Even in this Patent Document 2, if the position of the wedge piece (36) of the operating body (6) is left as it is, the blade edge (31) always protrudes outward, which also causes a safety problem.
The technique shown in Patent Document 3 has improved the disadvantages of cutting edge safety when not in use as shown in Patent Document 1 and Patent Document 2.
It is equipped with a protector that is a pressing bullet that elastically moves by pressing the main body around the outer periphery of the cutting blade, prevents the projection of the blade when not in use, improves safety, and presses the blade tip against the other when in use, It is said that the pressing bullet dents and escapes, and the blade is pushed out along with it to cut the opponent.

しかし、この技術においては刃物先端の突出量長さを、製作時点で固定取付けしているので切断深さが一定であり、対象物の厚薄および、加工公差内での寸法変動により、一枚切となったり、二枚切りとなったり、切断深さが安定し難かった。
それは、浅く切るには押圧弾片を固くして刃先を出難くしたり、軽い荷重を与えて刃先位置を浅くして薄切を行い、刃先の全量を出すには押圧荷重を大きくするか、押圧弾片を柔らかくして押し出し易くする等の操作が必要であるが、公差分の寸法バラ付きにより、更に面倒であった。 However, in this technique, the length of the protrusion at the tip of the blade is fixedly attached at the time of manufacture, so the cutting depth is constant, and due to the thickness of the object and dimensional fluctuations within the processing tolerance, one piece can be cut. It was difficult to stabilize the cutting depth.
It is hard to get the cutting edge harder by pressing the pressure piece to cut shallower, thin the cutting edge position by applying a light load, or increase the pressing load to get the full amount of the cutting edge, An operation such as softening the pressing bullet piece to make it easy to extrude is necessary, but it is more troublesome due to the tolerance of the difference in tolerance.

そして、押圧弾片が柔らか過ぎると、ポケット内などで擦れにより刃先が出るので、柔らかさの程度にも制限を要した。
そこで、本発明は、切断深さを、容易且つ精密に、有段階で正確に変更でき、しかもカッター非操作時には、刃先を保護具で覆うことで安全性も更に向上させようとする紙切カッターを提供しようとするものである。 If the pressed bullet is too soft, the cutting edge comes out due to rubbing in a pocket or the like, so the degree of softness is also limited.
Accordingly, the present invention provides a paper cutter capable of changing the cutting depth easily and precisely in a stepped manner and further improving safety by covering the blade edge with a protective tool when the cutter is not operated. Is to provide.

そして、刃先（７ａ）対応の保護アーム（８）部に刃が通過するためのスリット（１４）を開口しており、保護アーム（８）の一側部側に上動の荷重が作用すると、保護アーム（８）は、刃体（７）に非接触状態で本体下縁（１３）に接当するまで上動し、保護アーム（８）が上動した分、刃先（７ａ）の突出先端部（７ｂ）が外方に突出する。
（１５）は逃げ溝であって、スリット（１４）の上側に設けた、刃体収納箱（５）下端間との干渉防止溝である。
操作部（９）が、矢印イ方向へと実線から仮想線の間の動きで、連結具（１１）が上動し、スリット（１４）から下方突出する刃体（７）の突出先端部（７ｂ）が小さくなることに伴ない、カッター刃としての切断深さが浅くなる。 And when the slit (14) for a blade to pass to the protection arm (8) part corresponding to a blade edge (7a) is opened and a load of upward movement acts on one side of the protection arm (8), The protective arm (8) moves up until it comes into contact with the lower edge (13) of the main body in a non-contact state with the blade body (7), and the protruding tip of the blade edge (7a) is moved by the amount the protective arm (8) is moved upward. The part (7b) protrudes outward .
(15) is a relief groove, which is an interference prevention groove provided between the lower ends of the blade body storage box (5) and provided above the slit (14).
The operating portion (9) moves in the direction of the arrow a between the solid line and the imaginary line, the connecting tool (11) moves up, and the projecting tip of the blade body (7) projects downward from the slit (14) ( As 7b) becomes smaller, the cutting depth as the cutter blade becomes shallower.

図例では、揺動規制部（１０）に５〜１０段の位置調節を設けており、紙切カッターの紙切断深さを、言い換えると、保護アーム（８）下縁からの突出量を、最小０ｍｍ（ミリメートル、以下同じ。）から最大０．５mm程度の突出深さ変更位置段階としているから、保護アーム（８）押圧時に対する刃体（７）の突出先端部（７ｂ）寸法も、非突出とした安全係止位置から０．０５mm乃至０．１mmの１０〜５段の位置調節としている。 In the illustrated example, the rocking restricting portion (10) is provided with 5 to 10 stages of position adjustment, and the paper cutting depth of the paper cutting cutter, in other words, the amount of protrusion from the lower edge of the protective arm (8), Since the protrusion depth change position stage is from 0 mm (millimeter, the same applies hereinafter) to 0.5 mm at the maximum, the protrusion tip (7b) dimension of the blade body (7) when the protective arm (8) is pressed is also non- The position is adjusted in 10 to 5 steps from 0.05 mm to 0.1 mm from the protruding safety locking position.

このように図例の紙切カッターによれば、刃先（７ａ）の突出先端部（７ｂ）が，保護アーム（８）のスリット（１４）から外部に突出する量を０．０５mm乃至０．１mm刻みに調節可能としている。
そこで切断する相手の紙厚一枚に応じて、事前に刃体収納箱（５）の摺動高さ位置を、操作部（９）の移動角度位置や、刃体収納箱（５）下係止面（５）の間隙空間（Ｋ）への出入量等を目視して、予測判断しておくことができる。 As described above, according to the paper cutting cutter of the illustrated example, the protruding tip portion (7b) of the blade edge (7a) protrudes from the slit (14) of the protective arm (8) to the outside by 0.05 mm to 0.1 mm. Adjustable in increments.
Therefore, depending on the sheet thickness of the other party to be cut, the sliding height position of the blade body storage box (5) is set in advance, the moving angle position of the operation unit (9), and the blade body storage box (5) subordinate. The amount of entry / exit of the stop surface (5) into / from the gap space (K) can be visually predicted.

身の回りの紙類を手近な物から挙げると、薄いと感じるテイッシュペーパーで０．０４mm、財布に入れて邪魔になるレシートで０．０５mm、週刊誌では、カラー刷りのアート紙部分が０．０４〜０．０５mm、紙用紙部が０．０７mm、表紙部が０．１４mmであり、厚目に感じる名刺で０．２mm程度である。
また、新聞紙は０．０６mm、コピー用紙０．０８mm、封筒０．１mm程度と、夫々、微妙に異なっている。（全て、実測定値。） If you pick up the papers around you, 0.04mm for the texture paper that you feel is thin, 0.05mm for the receipt that gets in your wallet, and in the weekly magazine, the color art paper part is 0.04 ~ It is 0.05 mm, the paper sheet part is 0.07 mm, the cover part is 0.14 mm, and it is about 0.2 mm with a thick business card.
Newspaper is slightly different from 0.06mm, copy paper 0.08mm, and envelope 0.1mm. (All are actual measured values.)

これ等の、微差のある紙厚に対し、刃体（７）製作時の機械公差が０．０５mm乃至０．１mm程度あるので、保護アーム（８）下縁から突出量「０mm」で製作したとしても、公差範囲内での突出や凹みを防止できないが、１段当たり０．０５mm乃至０．１mmの刃体（７）突出先端部（７ｂ）の寸法調節を、１０段乃至５段の位置調節として、寸法公差精度を２倍程度向上可能な合成樹脂材の揺動規制部（１０）で調節可能としているので、充分な刃先突出入調節を行なえる。 The machine tolerance when manufacturing the blade (7) is about 0.05mm to 0.1mm for these slightly different paper thicknesses, so it can be manufactured with a protrusion of "0mm" from the lower edge of the protective arm (8). Even if it does, the protrusion and the dent within the tolerance range cannot be prevented, but the dimensional adjustment of the blade body (7) protruding tip (7b) of 0.05 mm to 0.1 mm per step can be performed by 10 steps to 5 steps. As the position adjustment, since it is possible to adjust by the swing restricting portion (10) of the synthetic resin material capable of improving the dimensional tolerance accuracy by about 2 times, sufficient blade edge protrusion adjustment can be performed.

即ち、新聞紙を一枚切り抜きたい場合厚み０．０６mm程度なので、刃先（７ａ）の突出先端部（７b）を０．０５ｍｍ突出可能（公差により開始基準端は、ズレている。）に調節している時は、ケース握持部（１）を強く新聞紙に押し付けて切断し、刃先（７ａ）の突出先端部（７b）を０．１ｍｍ突出可能に調節している時は、ケース握持部（１）を軽く弱く新聞紙に押し付けて切断すれば良い。 That is, when it is desired to cut out a piece of newspaper, the thickness is about 0.06 mm, so the protruding tip end (7b) of the blade edge (7a) is adjusted to be able to protrude 0.05 mm (the start reference end is displaced due to tolerance). When the case gripping part (1) is strongly pressed against the newspaper and cut, and when the protruding tip part (7b) of the blade edge (7a) is adjusted to be able to protrude 0.1 mm, the case gripping part ( It is only necessary to press 1) lightly and weakly against newspaper and cut it.

そして、揺動アーム（３）の長手方向遠方側にある操作部（９）の大きな斜方向の揺動動きを、揺動アーム（３）の長手方向基部側に連結した連結具（１１）の小さな上下方向揺動移動量に変換できるから、刃体収納箱（５）と刃先（７ａ）も連結具（１１）を介して小さな直線方向動きとなり、精密な刃先突出先端部（７ｂ）の突出量変更ができる。
また、保護アーム（８）の突出内端には荷重逃げ凹部（１６）が設けられ、該荷重逃げ凹部（１６）を設けることで、常に保護アーム（８）は肉厚の薄い凹部（１６）で容易に撓みながら、他の、保護アーム（８）全体形状の変化を小さくしているから、切断操作調節が楽に行なえる。 Then, the connecting tool (11) connected to the longitudinal base side of the swing arm (3) is connected with the large swinging motion of the operating portion (9) on the far side in the longitudinal direction of the swing arm (3). Since it can be converted into a small amount of swinging movement in the vertical direction, the blade body storage box (5) and the blade edge (7a) also move in a small linear direction via the connector (11), and the protrusion of the precise blade edge protruding tip (7b) The amount can be changed.
Further, a load escape recess (16) is provided at the protruding inner end of the protection arm (8), and the protection arm (8) is always provided with a thin recess (16) by providing the load escape recess (16). Since the change in the overall shape of the other protective arm (8) is made small while being easily bent, the cutting operation can be easily adjusted.

さらに、ケース握持部（１）は、正面視で縦長の略矩形状とし、ケース一方側に支点軸（２）や揺動アーム（３）、及び、案内レール（６）や刃体収納箱（５）等の主要部を偏在配置し、ケース他方側を外面の平坦部または内面空間部（Ｈ）としているので、ケース他方側の平坦部に広告宣伝文や社名を記載したシール紙を貼り付けたり、ケース空間部（Ｈ）を透明または半透明の材料とすることで、空間部に広告宣伝文や社名を記載したシール紙を挿入または貼り付けて、物品や会社名等の使用法や宣伝を容易に行なえる。 Further, the case gripping portion (1) is a substantially rectangular shape that is vertically long when viewed from the front. The fulcrum shaft (2), the swing arm (3), the guide rail (6), and the blade body storage box are provided on one side of the case. (5) Since the main parts such as 5 are unevenly distributed and the other side of the case is the outer flat part or the inner space part (H), sticker paper with advertising text and company name is pasted on the flat part on the other side of the case Or by using a transparent or translucent material for the case space (H), inserting or pasting sticker paper with advertising text or company name into the space, Promote easily.
