Description

【０００１】
【発明の属する技術分野】
本発明はペーパー切断機用切断刃の昇降装置に関する。
よリ詳細には、リンク装置と圧力シリンダーとをもって切断刃を昇降できるようにすることによって、切断機の作動の際に必要なエネルギー費用を低減し、しかも切断刃の切断圧力を高めると共に、切断刃の作動範囲を正確に制御できるようにしたペーパー切断機用切断刃の昇降装置に関するものである。
【０００２】
【従来の技術】
従来のペーパー切断機は切断刃を複雑なギア装置を利用して昇降させており、切断機の作動にかなりのエネルギー消耗があっただけではなく、自動化のためにかなり複雑な機械構成が要求され、費用と時間が多く消耗されており、ペーパーの切断時、ギアによリ昇降される切断刃はギアの公差によリ正確な作動範囲を制御することができないので、切断刃の下降時に棚と刃の接触により刃や棚が傷付きやすく、刃の切断力を減少させ、切断刃の頻煩な交換により機械維持費用が増加するという問題点があった。
【０００３】
【発明が解決しようとする課題】
本発明はこのような従来の問題点を解決するためになしたもので、切断刃の一側下部に油圧などの圧力シリンダーを設置し、このシリンダーと切断刃をリンク装置により連結し、シリンダーの作動により切断刃を昇降させるようにすることによって、切断圧力の増加と切断刃の正確な作動範囲の制御が可能なペーパー切断機用切断刃の昇降装置を提供することを課題とする。
【０００４】
【課題を解決するための手段】
上記課題を解決するために、本発明は、棚９に対して固定したガイド１０２に沿って昇降する切断刃１をもって、棚９に載置したペーパーを切断するペーパー切断機において、切断刃１の一側下方に油圧などの圧力シリンダー２を設置し、中間の折曲部３ｂを回転軸３ａで枢支させた下部回転体３の一端部を、シリンダーロッド２ａ端部に枢着し、下部回転体３の他端部を連結アーム４の一端部に枢着し、連結アーム４の他端部を、下部回転体３と連繋する回動制御具５の一端部と共に固定具８ｂに枢着し、一方、下部回転体３の上方には一端部を回転軸７ａで枢支させた上部回転体７の別の一端部を、切断刃１の側部に枢着した連結体６の他端部に枢着し、さらに上部回転体７の他端部を、作動レバー８に枢着し、上記固定具８ｂと作動レバー８は連結したガイド棒８ａに対していずれを嵌合すると共に、固定具８ｂと作動レバー８とをスプリング８ｃを介在させて連結した構成を有してなるペーパー切断機用切断刃の昇降装置を構成したことを特徴とする。

【０００５】
上記構成において、上部回転体７は、一端部を切断刃１の側部に連繋させると共に、他端部をリンク機構の連結部材、例えば作動レバー８に枢着し、これら枢軸２点に対して三角点となる他の一端部を切断刃支持用のガイド１０２端部などに回転軸７ａにより軸止させることができる。

【０００６】
【発明の実施の形態】
本発明の一実施の形態を添付図面によって説明する。
本発明のペーパー切断機用切断刃の昇降装置は、切断刃１の一側下部に設置された油圧シリンダー２を作動させ、油圧シリンダー２と切断刃１を連結するリンク装置を介して切断刃１を昇降させ、ペーパーを切断するようにしてある。
すなわち、本装置は、装置本体に固定されたペーパー受台としての棚９に対してガイド１０２を固定し、このガイドに沿って切断刃１が昇降するように配設してある。
切断刃１の一側下方には、油圧などの圧力シリンダー２を設置し、ヘの字状の下部回転体３の中間の折曲部３ｂを回転軸３ａで装置側に枢支し、この下部回転体３の一端部を、シリンダー２のシリンダーロッド２ａ端部に枢着し、他端部を連結アーム４の一端部に枢着し、連結アーム４の他端部を回動制御具５の一端部と共に、下部回転体３の上側に配置した固定具８ｂに枢着し、回転制御具５は他端側で下部回転体３の中間部下側を挟持させ、固定具８ｂはガイド棒８ａの下部に昇降可能に嵌合してある。
【０００７】
また、下部回転体３の上方には上部回転体７を配設し、上部回転体７は三角形状のプレートとし、その一端部をガイド１０２の下部に回転軸７ａで枢支させ、、別の一端部を、切断刃１の側部に枢着した連結体６の他端部に枢着し、上部回転体７の他端部を、作動レバー８に枢着してあり、作動レバー８には下方に延びたガイド棒８ａの上端部を固定し、ガイド棒８ａにはコイルスプリング８ｃを遊嵌し、ガイド棒下部に上記固定具８ｂを嵌合し、スプリング８ｃの両端をそれぞれ作動レバー８と固定具８ｂに固定して、両者８，８ｂを連結することにより、切断刃１の昇降距離を制御できるようにしてある。
【０００８】
つまり、図３から図４のごとく、油圧シリダー２のシリンダーロッド２ａが上昇すると、シリンダーロッド２ａに一端が枢着された下部回転体３が、回転軸３ａを中心として回転しながら他端部に軸連結された連結アーム４を引くが、シリンダーロッド２ａの上下動に伴う連結アームの上下移動は、連結アーム４の連結部５ｂに枢着され、かつ他端部で下部回転体３の中間部を挟持した回転制御具５によって安定した一定の反復運動となることができる。
連結アーム４は固定具８ｂを引っ張り、連結された作動レバー８を引っ張る。作動レバー８の移動は上部回転体７を回転させ、上部回転体７の他端部に軸連結された連結体６を引き、切断刃１を引き、切断刃１が下降し、ペーパーが切断される。
【０００９】
この際、回動制御具５が作動レバー８の作動範囲を制御し、安定した上下動を実現させるので、各連結部材の連動に伴うリンク機構は正確な動作を遂行することができ、切断刃１は両側部のガイド１０２に沿って上下動しながら棚９に載置されたペーパーを切断することになる。スプリング８ｃは緩衝作用を果たす。
このように、油圧などの圧力シリンダー２とリンク機構とを利用するとシリンダ２の可動範囲を調整することにより切断刃１の作動範囲を正確に制御し得るため、ペーパーを切断するために切断刃１が下降すべき最低点を正確に制御できるので相当精密なペーパー切断が可能になるだけではなく、このような精密制御により刃と棚９の食い込み接触を防止するので刃の損傷を未然に予防して切断刃１の寿命を長くすることができる。
【００１０】
【発明の効果】
上述した通り、本発明によれば、切断刃の作動範囲を正確に制御することによって刃が棚に食い込み接触して発生する損傷を予防し、切断刃の寿命を長くし、無理な作用を防止してエネルギーが節減されるペーパー切断機となるとともに、切断刃の破損等による交換や購入費用等を低減することができ、生産性を高める効果がある。

[0005]
In the above configuration, the upper rotating body 7 has one end connected to the side of the cutting blade 1 and the other end pivotally connected to a connecting member of the link mechanism, for example, the operating lever 8. The other end serving as a triangular point can be fixed to the end of the guide 102 for supporting the cutting blade by the rotating shaft 7a.

[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the accompanying drawings.
The lifting device for a cutting blade for a paper cutting machine according to the present invention operates a hydraulic cylinder 2 installed at a lower portion of one side of the cutting blade 1, and connects the cutting blade 1 via a link device connecting the hydraulic cylinder 2 and the cutting blade 1. Is raised and lowered to cut the paper.
That is, in the present apparatus, the guide 102 is fixed to the shelf 9 as a paper receiving table fixed to the apparatus main body, and the cutting blade 1 is arranged to move up and down along the guide.
A pressure cylinder 2 such as a hydraulic pressure is installed below one side of the cutting blade 1, and an intermediate bent portion 3 b of a lower U-shaped lower rotating body 3 is pivotally supported by a rotating shaft 3 a to the apparatus side. One end of the rotating body 3 is pivotally connected to the end of the cylinder rod 2a of the cylinder 2, the other end is pivotally connected to one end of the connecting arm 4, and the other end of the connecting arm 4 is Along with one end, it is pivotally attached to a fixture 8b disposed above the lower rotating body 3, the rotation control tool 5 clamps the lower end of the lower rotating body 3 at the other end, and the fixing tool 8b is connected to the guide rod 8a. The lower part is fitted to be able to move up and down.
[0007]
An upper rotator 7 is disposed above the lower rotator 3. The upper rotator 7 is a triangular plate. One end of the upper rotator 7 is pivotally supported at the lower portion of the guide 102 by a rotation shaft 7a. One end is pivotally connected to the other end of the connector 6 pivotally connected to the side of the cutting blade 1, and the other end of the upper rotating body 7 is pivotally connected to the operating lever 8. Is fixed to the upper end of the guide rod 8a extending downward, the coil spring 8c is loosely fitted to the guide rod 8a, the fixing tool 8b is fitted to the lower part of the guide rod, and both ends of the spring 8c are respectively actuated by the operating levers 8. And the fixture 8b, and by connecting the two 8, 8b, the up-and-down distance of the cutting blade 1 can be controlled.
[0008]
That is, as shown in FIGS. 3 and 4, when the cylinder rod 2a of the hydraulic cylinder 2 rises, the lower rotating body 3 having one end pivotally connected to the cylinder rod 2a rotates around the rotating shaft 3a to the other end. The connecting arm 4 connected to the shaft is pulled, but the vertical movement of the connecting arm caused by the vertical movement of the cylinder rod 2a is pivotally attached to the connecting portion 5b of the connecting arm 4 and the other end is located at the intermediate portion of the lower rotating body 3. By means of the rotation control tool 5 holding the, a stable and constant repetitive motion can be achieved.
The connecting arm 4 pulls the fixture 8b and pulls the connected operating lever 8. The movement of the operating lever 8 rotates the upper rotating body 7, pulls the connecting body 6 connected to the other end of the upper rotating body 7, pulls the cutting blade 1, the cutting blade 1 descends, and the paper is cut. You.
[0009]
At this time, since the rotation control tool 5 controls the operation range of the operation lever 8 and realizes a stable vertical movement, the link mechanism associated with the interlocking of each connecting member can perform an accurate operation, and the cutting blade 1 cuts the paper placed on the shelf 9 while moving up and down along the guides 102 on both sides. The spring 8c has a buffer function.
As described above, when the pressure cylinder 2 such as a hydraulic pressure and the link mechanism are used, the operating range of the cutting blade 1 can be accurately controlled by adjusting the movable range of the cylinder 2. In addition to being able to precisely control the lowest point at which the blade should descend, not only can the paper be cut quite precisely, but such precise control prevents biting contact between the blade and the shelf 9, thereby preventing damage to the blade. Thus, the life of the cutting blade 1 can be extended.
[0010]
【The invention's effect】
As described above, according to the present invention, by accurately controlling the operating range of the cutting blade, it is possible to prevent the damage caused by the blade biting into and contacting the shelf, prolong the life of the cutting blade, and prevent unreasonable action. As a result, an energy-saving paper cutting machine can be obtained, and replacement and purchase costs due to breakage of the cutting blade can be reduced, thereby improving productivity.
