【発明の属する技術分野】
本発明は、紙切断装置、更に詳しくは各種印刷装置等の機器に装着され印字記録後に給送されてくる縦長の記録紙をカッタ刃に当接させて更に移動させることにより記録紙を切断する紙切断装置に関する。
【0002】
【従来の技術】
この種の従来の紙切断装置を図4乃至図6に示す。図6(a)は従来技術の印刷装置に配置されたカッタ部の平面図であり、図6(b)はカッタ刃の詳細図である。図5は従来の紙切断装置のカッタ取付部の代表例の断面説明図、図4はカッタ刃の詳細図である。
【0003】
紙切断装置は、プリンター等の各種印刷機器3の出口部に配置されており、カッタ刃7はカッタ取付フレーム2に取付けられその刃部が切断位置の上流側の搬送経路と略平行となるように配置されている。カッタ刃7は、図4に示すように、刃部の形状はノコギリ刃状の刃高Hおよび等ピッチPで形成され、且つその刃先の先端部ウは直線上に多数並んでいるものである。
【0004】
上記構成のものにおいては、印刷機器3から送り出されたレシート6は、アから上方の矢印イ方向へ搬送され、カット時にオペレータにより矢印オ方向へ引っ張られ、カッタ7の先端部ウに当接して切断される。この場合、カッタの刃部面7aと切断位置の上流側のレシート6とのなす曲げ角度θ1は大きいほど、また引っ張り角度θ2は小さいほど切れ味は向上するものである。
【0005】
また、他の従来例として例えば、実開平2ー65561号公報記載のように、カッタの刃先の形状を両端部と中央部とで変えているものがあった。この何れもが、その刃先の先端が直線上に配置されているものであり、全て刃先が記録紙と同時に当接可能に構成されて記録紙の出口に配置されているものであった。
【0006】
【発明が解決しようとする課題】
しかしながら、従来の紙切断装置では、全紙幅に多数の刃先が当接していることから、切断するに大きな力を要することから、オペレーターは刃部に対してレシートを一方の端から切断しようと斜めに当接させる。その結果、レシートは一方の端が刃部から外れて全幅がカットされず紙の端部がちぎれてしまうという課題があった。レシート6と刃先部ウとのいつきが悪い場合はレシート6が幅方向に移動して刃部から外れる量が多くなり、切断品質は大変悪いものであった。
【0007】
又、この従来例の課題を防止するために、切断時のレシートが刃部付近で幅方向に移動しないように常時レシートと当接するように構成されるものもあったがその場合は、レシートの搬送時、特にはレシートの挿入時にレシートが刃部と当接して紙ジャム(紙詰まり)の原因となった。
【0008】
本発明の目的は、上述の欠点を除去し、カッタの記録紙切断時に紙の全幅がカットされ端部のちぎれを防止する切れ味性能の向上および、搬送される記録紙のカッタ刃への引っかかりによる紙ジャムの防止の両立をはかった信頼性の高い紙切断装置を提供することにある。
【0009】
【課題を解決するための手段】
本発明の紙切断装置は、各種印刷装置内部から給送されてくる記録紙をカッタ刃に当接させて切断する手動式の紙切断装置において、
前記カッタ刃は、前記記録紙とは記録紙幅の両端から当接するように刃の先端部が湾曲を形成する鋸歯状に形成され、
前記鋸歯状の刃先の高さは両端部の範囲のものは中央部の範囲のものよりも高く形成されると共に、刃先角度は、両端部の範囲の刃先角度が中央部の範囲の刃先角度よりも小さく形成されていることを特徴とする。
【0010】
上記構成にすることにより、カッタ刃にたいして記録紙が幅方向に所望する位置から多少離れた位置に搬送されたとしても、切断時に記録紙をカッタ側に移動すると刃の先端部が湾曲に形成されているので、記録紙の必ず両端から当接して切断され、記録紙がいったん切断し始めると切断しやすくなる応力集中効果から切れ味は向上する。
また、上記構成にすることにより、切断時に記録紙とは複数の刃先が当接するので相対移動を防ぎ切れ味は向上する。
また、上記構成にすることにより、カッタ刃は、中央部に比して両端側の刃先が鋭利で且つ突出しているので、更に両端側から切断されやすくなると共に、切断時の力を少なくすることができるのでより切れ味が向上する。
【0015】
また更には、カッタ刃の上流側に記録紙の搬送路の一部を形成する案内部であって、記録紙の幅方向にカッタ刃側を底部とし両端側が突出する略凹形状曲面の案内部を備えていることを特徴とする。
【0016】
上記構成にすることにより、記録紙の直進性が向上するのでカッタ刃と記録紙の幅方向の相対位置は大きく変化しないので記録紙の幅に対しカッタ刃の幅を大きくとる必要がなく小型化できる。
【0017】
従って、本発明によれば、カッタの記録紙切断の切れ味性能(ロール紙切断性能)が向上し、かつ送り出される記録紙の刃先への引っかかりによるジャム(紙詰まり)の発生がなくなる。
【0018】
【発明の実施の形態】
以下、本発明の一実施形態の一例を、図面に基づいて説明する。
【0019】
図1(A)は、本発明の一実施例のカッタの全体の形状を示す正面図、同図(B)はその側面図である。
【0020】
図1において、10はシート材を切断するカッタであり、11はカッタ10の下部に開孔した一対の取付用孔である。また、10−1,10ー2はカッタ10の刃先の両端部、10ー3はその刃先の残り中央部、θ1はカッタ10の曲げ角度、H1、H2は刃先の高さ、P1、P2は刃先のピッチ、Z1、Z2は刃先角度、Rは刃先端ウの全体形状の曲率半径である。
【0021】
図1のように本願発明のカッタ刃10は、刃先端ウが曲率Rの軌跡上にあって、且つ、その高さは両端部10−1,10ー2の範囲のものは、中央部10−3の範囲のものよりも高く形成されている。
【0022】
更に、カッタ刃10の刃先角度は、両端部10ー1,10ー2の範囲の刃先角度Z1が中央部10ー3の範囲の刃先角度Z2よりも、安全性に支障のない程度まで小さく形成されている。
【0023】
従って、実施例のカッタ刃10は、図示のようにわん曲形状となり、カッタ刃両端部分は刃先が鋭角で刃高が高い細目ノコギリ刃状となり、カッタ刃中央部分は刃先角度が少し広く刃高が低い太目ノコギリ刃状となる。そして、両端の細目部分および中央の太目部分の各刃先をつなぐと、中央部分が低いわん曲形状をもったカッタとなる。
【0024】
図2は、図1のカッタ刃10を取付けた本発明の紙切断装置の構成例を示す。
【0025】
従来例の図5とはカッタ刃が本願のカッタ刃10に置き換わったものであり、従来と同じもしくは同等の部品には同符号を付した。
【0026】
次に、レシートの切断状況を説明する。プリンター等の機器3のアの位置から矢印イ方向へ送り出されたレシートは、カット時にオペレータにより矢印オ方向へ引っ張られ、カッタ刃10の先端部ウに当接する。カッタ刃10の先端部ウは、中央部10−3がわん曲により後退していること、及び両端部10−1,10−2が中央部10−3より高いことより、当接初期において、レシート6はその両端部のみががカッタ刃10と当接する。
【0027】
レシート6を更に矢印オ方向へ引っ張って移動させると、レシート6は、その両端部から切断されて中央部も切断される。
【0028】
特に、本願は、カッタ刃10の両端部分に鋭角の刃先を配置したことにより、レシート6との食いつきが良好で、レシート6幅方向に移動しにくいものである。例え、移動したとしても、刃の先端部が湾曲形状となっていることから中央部に移動されるので、レシート6がカッタ刃10から外れることはなく、従って、カットされないでちぎれてしまうことは無く、切断品質は大きく向上するものとなる。
【0029】
更に、カッタ刃10による切れ味は、カッタ刃10の先端部ウにおいて、案内部である刃部面10aと切断位置の上流側のレシート6とのなす曲げ角度θ1を大きくした方がよくなる。
【0030】
上ケース4とカッタ刃10の先端部ウまでの寸法カは近い方がより引っ張り角度θ2を小さく設定できる。レシート6の切断時は、カッタ刃10の刃の先端部に対するレシートの引っ張り角度θ2が鋭角なほど、切断性能が向上する。
【0031】
尚、本実施例では、カッタ刃10の中央部を引くし刃先角度も大きくすることにより、手に怪我をしてしまう等の危険性が大きく低下させることができた。
【0032】
次に、本願実施の形態の第2例を図3を用いて説明する。
【0033】
さらに、図3は、カッタの平面図であり、前述の第1例との異なる点は、第1例の案内部の刃部面10aが平面であるのに対し第2例の案内部である刃部面10bは、その面の中央部がレシート6から離れるような凹面に形成した点である。
【0034】
このことにより、レシート6の両端部のくいつきがより向上すると共に、当接する記録紙も凹形状となって記録紙の剛性がましてその直進性が大きく向上する。従って、レシートを手切りカットするときの力の方向が、多少変わってもその進行方向に与える影響が少なくなることことから、記録紙の幅に対しカッタ刃の幅を大きくとる必要がなく小型化できる。
【0035】
また、操作からみると右手を使って右側から、左手を使って左側からというように、左右どちらからでも円滑にカットすることができる。
【0036】
また、紙案内の出口の形状をわん曲形状にして記録紙に曲面形状をつける構造にすると、更にカット性能が向上する。
【0037】
上述の本実施例は、人の手など外部からの力によってレシートをカッタの刃に押し当てて切断する紙切断装置に関するものであり、外力の方向には図2に示すような矢印オ方向を中心にしてある程度のバラツキがあるので、比較的良好な切れ味を実現する上では、図2に示したθ2の角度をより鋭角にするよう、上ケースとの距離カおよび上ケースに突起物のない形状等を心がけることが大切である。
【0038】
【発明の効果】
以上述べたように本発明によれば、カッタの先端を曲げて接触角度を大きくするのではなく全体の曲げ角度を大きくして、レシートの送り出しを円滑にすると供に、カッタ刃にわん曲形状をつけ両端部を高くすることにより引っ張り角度をできるだけ小さくしてよりレシートの接触をよくしている。またカッタ刃先の形状も両端を刃先角度の鋭角な、刃高の高い細目ノコギリ刃状に形成し、残りの中央部の刃先を刃高の低い刃先角度の広い、ピッチの広い太目ノコギリ刃状に形成したので、レシートの端部がちぎれることなくカットできることとなりレシートの切れ味を向上させ、尚かつ安全面にも配慮したカッタ刃にすることができた。さらに、中央部が低い曲面形状のカッタ刃を使えば、レシートの中央部に向かって曲面が付いているので、手切りカットするとき力の方向に刃が向いているため、左右どちらからでも滑らかにカットすることができる。また、印字後の記録紙に紙案内にわん曲形状をつけることにより、カッタが通常のものでも両端部の接触がよくなり滑らかにカットすることができる。従って本発明によれば、カッタのレシート切断の切れ味性能(シート切断性能)が向上し、かつ送り出されるレシートのカッタ刃先への引っかかりによる紙ジャム(紙詰り)の発生がなくなる。また、手切りカットの操作性の向上がみこまれる。
【0039】
よって、本発明によれば、レシートの切断性能、操作性能を大幅に改善し、レシートの発行等による切断手段を、簡単な構成で尚かつ極めて低コストで提供できる大きな効果がある。

BACKGROUND OF THE INVENTION
The present invention cuts a recording paper by contacting a cutter blade with a vertically long recording paper that is mounted on a paper cutting device, more specifically, various printing devices, and is fed after printing and recording. The present invention relates to a paper cutting device.
[0002]
[Prior art]
A conventional paper cutting apparatus of this type is shown in FIGS. FIG. 6A is a plan view of a cutter unit arranged in a conventional printing apparatus, and FIG. 6B is a detailed view of a cutter blade. FIG. 5 is a cross-sectional explanatory view of a typical example of a cutter mounting portion of a conventional paper cutting device, and FIG. 4 is a detailed view of a cutter blade.
[0003]
The paper cutting device is disposed at the exit of various printing devices 3 such as a printer, and the cutter blade 7 is attached to the cutter mounting frame 2 so that the blade is substantially parallel to the conveyance path on the upstream side of the cutting position. Is arranged. As shown in FIG. 4, the cutter blade 7 is formed with a saw blade-shaped blade height H and an equal pitch P, and a large number of tips C of the blade tip are arranged in a straight line. .
[0004]
In the above configuration, the receipt 6 sent out from the printing device 3 is conveyed in the direction indicated by the arrow A above from A, pulled by the operator in the direction indicated by the arrow O at the time of cutting, and brought into contact with the distal end portion C of the cutter 7. Disconnected. In this case, the sharpness improves as the bending angle θ1 formed by the cutter blade surface 7a and the receipt 6 upstream of the cutting position increases and as the pulling angle θ2 decreases.
[0005]
Further, as another conventional example, for example, as described in Japanese Utility Model Laid-Open No. 2-65561, there is one in which the shape of the cutting edge of the cutter is changed between the both end portions and the central portion. In either case, the tip of the blade edge is arranged on a straight line, and all the blade edges are arranged so as to be able to contact simultaneously with the recording paper and are arranged at the outlet of the recording paper.
[0006]
[Problems to be solved by the invention]
However, in the conventional paper cutting device, since a large number of cutting edges are in contact with the entire paper width, a large force is required for cutting. Therefore, the operator is inclined to cut the receipt from one end with respect to the blade portion. Abut. As a result, there was a problem that one end of the receipt was detached from the blade portion and the entire width was not cut and the end portion of the paper was torn off. When the contact between the receipt 6 and the blade edge portion c was bad, the amount of the receipt 6 moving in the width direction and coming off from the blade portion increased, and the cutting quality was very bad.
[0007]
In addition, in order to prevent the problems of this conventional example, there are some which are configured to always contact the receipt so that the receipt at the time of cutting does not move in the width direction near the blade portion. When transporting, especially when inserting a receipt, the receipt abuts against the blade, causing a paper jam (paper jam).
[0008]
The object of the present invention is to eliminate the above-mentioned drawbacks, improve the sharpness performance of cutting the entire width of the paper when cutting the recording paper of the cutter and prevent the tearing of the edge, and catching the conveyed recording paper on the cutter blade It is an object of the present invention to provide a highly reliable paper cutting device that achieves both paper jam prevention.
[0009]
[Means for Solving the Problems]
The paper cutting device of the present invention is a manual paper cutting device that cuts recording paper fed from the inside of various printing devices in contact with a cutter blade,
The cutter blade is formed in a sawtooth shape in which the tip of the blade forms a curve so as to come into contact with the recording paper from both ends of the recording paper width ,
The height of the serrated blade edge is formed higher in the range of both ends than in the range of the central portion, and the blade edge angle is larger than the blade edge angle in the range of the central portion. characterized that you are also formed small.
[0010]
With the above configuration, even if the recording paper is conveyed to a position slightly apart from the desired position in the width direction with respect to the cutter blade, when the recording paper is moved to the cutter side during cutting, the tip of the blade is formed in a curved shape. Therefore, the sharpness of the recording paper is improved by the stress concentration effect that makes it easy to cut once the recording paper starts to cut.
Further, with the above configuration, a plurality of cutting edges come into contact with the recording paper at the time of cutting, so that relative movement is prevented and sharpness is improved.
In addition, with the above configuration, the cutter blade has a sharper and more protruding edge than the center portion, so that it is easier to be cut from both ends and the force at the time of cutting is reduced. Can improve the sharpness.
[0015]
Still further, a guide portion that forms a part of the recording paper conveyance path upstream of the cutter blade, the guide portion having a substantially concave curved surface that protrudes from the cutter blade side at the bottom in the width direction of the recording paper. It is characterized by having.
[0016]
By adopting the above configuration, the straightness of the recording paper is improved, so the relative position in the width direction of the cutter blade and the recording paper does not change greatly, so it is not necessary to make the cutter blade wider than the width of the recording paper and downsizing it can.
[0017]
Therefore, according to the present invention, the cutting performance (roll paper cutting performance) of the recording paper of the cutter is improved, and jamming (paper jam) due to catching of the fed recording paper on the blade edge is eliminated.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
[0019]
FIG. 1A is a front view showing the overall shape of a cutter according to an embodiment of the present invention, and FIG. 1B is a side view thereof.
[0020]
In FIG. 1, reference numeral 10 denotes a cutter that cuts the sheet material, and reference numeral 11 denotes a pair of mounting holes opened in the lower part of the cutter 10. Further, 10-1 and 10-2 are both end portions of the cutting edge of the cutter 10, 10-3 is a remaining central portion of the cutting edge, θ1 is a bending angle of the cutter 10, H1 and H2 are heights of the cutting edge, and P1 and P2 are The pitch of the cutting edge, Z1 and Z2 are the cutting edge angle, and R is the curvature radius of the entire shape of the blade tip c.
[0021]
As shown in FIG. 1, the cutter blade 10 of the present invention has a blade tip C on the locus of curvature R and a height in the range of both end portions 10-1 and 10-2 is the center portion 10. It is formed higher than the range of -3.
[0022]
Further, the cutting edge angle of the cutter blade 10 is formed to be smaller to the extent that the cutting edge angle Z1 in the range of both end portions 10-1 and 10-2 does not hinder the safety than the cutting edge angle Z2 in the range of the central portion 10-3. Has been.
[0023]
Therefore, the cutter blade 10 according to the embodiment has a curved shape as shown in the drawing, the cutter blade both ends have a fine saw blade shape with a sharp edge and a high blade height, and the cutter blade has a slightly wider blade angle at the blade edge angle. Is a low-profile saw blade. When the cutting edges of the fine portions at both ends and the thick portions at the center are connected, a cutter having a curved shape with a low central portion is obtained.
[0024]
FIG. 2 shows a configuration example of the paper cutting device of the present invention to which the cutter blade 10 of FIG. 1 is attached.
[0025]
In FIG. 5 of the conventional example, the cutter blade is replaced with the cutter blade 10 of the present application, and the same reference numerals are given to the same or equivalent parts as the conventional one.
[0026]
Next, the cutting state of the receipt will be described. The receipt sent in the direction of the arrow A from the position of the device 3 such as a printer is pulled in the direction of the arrow E by the operator at the time of cutting, and comes into contact with the distal end c of the cutter blade 10. At the initial stage of contact, the front end portion c of the cutter blade 10 has the central portion 10-3 retracted due to bending and both end portions 10-1 and 10-2 are higher than the central portion 10-3. Only the both ends of the receipt 6 abut against the cutter blade 10.
[0027]
When the receipt 6 is further pulled and moved in the direction of arrow E, the receipt 6 is cut from both ends thereof, and the central portion is also cut.
[0028]
In particular, according to the present application, the cutting edge with the acute angle is disposed at both end portions of the cutter blade 10 so that the biting with the receipt 6 is good and the movement in the width direction of the receipt 6 is difficult. Even if it moves, since the tip of the blade has a curved shape and is moved to the center, the receipt 6 will not come off from the cutter blade 10, and therefore it will be cut without being cut. In this case, the cutting quality is greatly improved.
[0029]
Further, the sharpness of the cutter blade 10 is preferably improved by increasing the bending angle θ1 between the blade surface 10a serving as a guide and the receipt 6 on the upstream side of the cutting position at the tip end c of the cutter blade 10.
[0030]
The closer the distance between the upper case 4 and the tip of the cutter blade 10 is, the smaller the pulling angle θ2 can be set. When cutting the receipt 6, the cutting performance improves as the receipt pull angle θ2 with respect to the tip of the cutter blade 10 becomes sharper.
[0031]
In the present embodiment, by pulling the center portion of the cutter blade 10 and increasing the blade edge angle, the risk of injury to the hand could be greatly reduced.
[0032]
Next, a second example of the present embodiment will be described with reference to FIG.
[0033]
Further, FIG. 3 is a plan view of the cutter. The difference from the first example described above is the guide part of the second example, whereas the blade part surface 10a of the guide part of the first example is flat. The blade surface 10b is a point formed in a concave surface such that the central portion of the surface is separated from the receipt 6.
[0034]
As a result, the clinging of the both ends of the receipt 6 is further improved, and the recording paper that comes into contact also becomes concave, which increases the rigidity of the recording paper and greatly improves its straightness. Therefore, even if the direction of force when manually cutting the receipt is slightly changed, the effect on the direction of travel is reduced, so there is no need to increase the width of the cutter blade relative to the width of the recording paper. it can.
[0035]
From the viewpoint of operation, the right hand can be used to cut from the right side, and the left hand to use the left side.
[0036]
In addition, when the shape of the exit of the paper guide is curved and the recording paper is curved, the cutting performance is further improved.
[0037]
The above-described embodiment relates to a paper cutting device that presses a receipt against a cutter blade by an external force such as a human hand, and cuts the direction of an arrow O as shown in FIG. Since there is some variation at the center, in order to achieve a relatively good sharpness, there is no protrusion on the distance from the upper case and the upper case so that the angle θ2 shown in FIG. It is important to keep in mind the shape.
[0038]
【The invention's effect】
As described above, according to the present invention, the cutting edge is bent to increase the overall bending angle rather than bend the tip of the cutter to make the receipt smooth, and the cutter blade is curved. The height of both ends is increased by making the pulling angle as small as possible to improve the contact of the receipt. The cutter edge also has a sharp edge with a sharp edge and a fine saw blade shape with a high blade height. Since it was formed, the end portion of the receipt could be cut without tearing, and the sharpness of the receipt could be improved, and a cutter blade that also considered safety could be obtained. In addition, if you use a cutter blade with a curved surface at the center, the curved surface is attached toward the center of the receipt. Can be cut. Further, by forming a curved shape in the paper guide on the recording paper after printing, even if the cutter is a normal one, the contact at both ends is improved and the paper can be cut smoothly. Therefore, according to the present invention, the cutting performance (sheet cutting performance) of the receipt cutting of the cutter is improved, and the occurrence of paper jam (paper jam) due to catching of the delivered receipt on the cutter blade edge is eliminated. Moreover, the improvement of the operability of the hand cut is seen.
[0039]
Therefore, according to the present invention, there is a great effect that the cutting performance and operating performance of the receipt are greatly improved, and a cutting means by issuing a receipt or the like can be provided with a simple configuration and at an extremely low cost.
