Description

本発明は、往復移動刃物で板状部材を切断する板状部材用カッターに関する。 The present invention relates to a plate member cutter for cutting a plate member with a reciprocating cutter.

シート状又はテープ状で厚さがあまり厚くない平面的な板状部材を切断するカッターとして、図３に示すものが知られている。この種のカッターは、移動刃物１０と、この移動刃物１０と協同して板状部材Ｗを切断する固定刃物２０とを有している。 A cutter shown in FIG. 3 is known as a cutter that cuts a planar plate-like member that is sheet-like or tape-like and is not so thick. This type of cutter has a movable blade 10 and a fixed blade 20 that cuts the plate member W in cooperation with the movable blade 10.

移動刃物１０の刃先１１は、切り始め側１２側が切り終り側１３側より固定刃物２０側になるように傾斜して形成されている。これにより、板状部材Ｗを切り始め側１２から切り終り側１３に向かって順次切断することができ、切断が容易に行える。また移動刃物１０の刃先１１と固定刃物２０の刃先２１とのクリアランスが生じないように、移動刃物１０の切り始め側１２側の固定刃物２０には、移動刃物１０をガイドするガイド部２２が設けられている。 The cutting edge 11 of the movable blade 10 is formed so as to be inclined so that the cutting start side 12 side is closer to the fixed cutting tool 20 side than the cutting end side 13 side. Thereby, the plate-shaped member W can be cut | disconnected sequentially from the cutting start side 12 toward the cutting end side 13, and it can cut | disconnect easily. In addition, a guide portion 22 for guiding the movable blade 10 is provided on the fixed blade 20 on the cutting start side 12 side of the movable blade 10 so that the clearance between the blade edge 11 of the movable blade 10 and the blade edge 21 of the fixed blade 20 does not occur. It has been.

移動刃物１０の上方の側方には、支軸１４、１４が設けられており、支軸１４、１４は、図示しない駆動手段で上下駆動される移動ベース３０に回転自在に支承されている。そして、移動刃物１０の切り始め側１２側の刃先がガイド部２２に圧接するように、移動刃物１０と移動ベース３０間にはスプリング３１が配設されている。なお、図において、θ１は移動刃物１０の逃げ角、θ２は固定刃物２０の逃げ角を示す。
この種のカッターに関連するものとして、例えば特許文献１が挙げられる。
特開２００７−１０５８０８号公報 Support shafts 14 and 14 are provided on the upper side of the movable blade 10, and the support shafts 14 and 14 are rotatably supported by a moving base 30 that is driven up and down by a driving means (not shown). A spring 31 is disposed between the moving blade 10 and the moving base 30 so that the cutting edge on the cutting start side 12 side of the moving blade 10 is in pressure contact with the guide portion 22. In the figure, θ1 represents the clearance angle of the movable blade 10, and θ2 represents the clearance angle of the fixed blade 20.

JP 2007-105808 A

移動刃物１０の刃先１１と固定刃物２０の刃先２１のクリアランスを０で両刃物１０、２０を切り始めより切り終りまで順番に当てるためには、通常図３（ａ）、（ｃ）に示すように、刃先１１と２１が平行ではなく、刃先１１の切り終り側１３を固定刃物２０側に傾けている。これにより、両刃物１０、２０のクリアランスが０に保たれ、綺麗に切断できる。しかし、この構造であると、図４（ｂ）に示すように、送りローラ４０、４１と押さえローラ４２、４３で板状部材Ｗの切断部の両側部分をきちんと押さえて切断しないと、板状部材Ｗが曲がるという問題があった。これに対して、刃先１１と２１を平行にすると、通常は製作誤差によりクリアランスを０に保つことができない。 In order to apply the clearance between the blade edge 11 of the movable blade 10 and the blade edge 21 of the fixed blade 20 to 0 in order from the start to the end of cutting both the blades 10 and 20, as shown in FIGS. 3 (a) and 3 (c). Further, the cutting edges 11 and 21 are not parallel, and the cutting end side 13 of the cutting edge 11 is inclined to the fixed blade 20 side. Thereby, the clearance of both the blades 10 and 20 is maintained at 0, and can be cut cleanly. However, with this structure, as shown in FIG. 4 (b), if the feed rollers 40 and 41 and the pressing rollers 42 and 43 are not pressed by cutting both sides of the cutting portion of the plate-like member W properly, There was a problem that the member W bends. On the other hand, if the cutting edges 11 and 21 are made parallel, the clearance cannot normally be kept at 0 due to a manufacturing error.

このように、板状部材Ｗの切断部の両側部分をきちんと押さえていないと、板状部材Ｗが刃先１１と２１の間に引き込まれて斜めにカーブを描いて切断される。また非常に軟らかい板状部材Ｗでは、押さえローラ４２、４３で押さえていても切断終了間際は引き込まれる。この原因は、移動刃物１０が固定刃物２０と平行でないため、僅かに動き、そのために引き込み力が発生するために起こる。 Thus, if the both sides of the cutting part of the plate-like member W are not pressed down properly, the plate-like member W is drawn between the blade edges 11 and 21 and cut in an oblique curve. Further, the very soft plate-like member W is pulled in just before the end of cutting even if it is pressed by the pressing rollers 42 and 43. This cause occurs because the moving blade 10 is not parallel to the fixed blade 20 and moves slightly, and therefore a pulling force is generated.

本発明の課題は、切断部の両側をきちんと押さえなくても、綺麗に切断することができる板状部材用カッターを提供することにある。 The subject of this invention is providing the cutter for plate-shaped members which can be cut | disconnected neatly, without pressing down both sides of a cutting part properly.

上記課題を解決するための本発明の請求項１は、相対向して配設され、一方の刃物の刃先は、他方の刃物の刃先に対して傾斜して形成され、相対的に移動して板状部材を切断する２個の刃物を有する板状部材用カッターにおいて、２個のいずれかの刃物には、切り始め側及び切り終り側にそれぞれ対応する刃物側に伸びて該刃物をガイドするガイド部が設けられており、ガイド部を有しない刃物は、刃先がガイド部に圧接するように弾性部材で付勢されていることを特徴とする。 According to a first aspect of the present invention for solving the above-mentioned problem, the blade edge of one of the blades is formed to be inclined with respect to the blade edge of the other blade and moved relatively. In a plate member cutter having two blades for cutting a plate member, each of the two blades extends to the blade side corresponding to the cutting start side and the cutting end side and guides the blade. A cutting tool that is provided with a guide part and does not have a guide part is characterized in that it is urged by an elastic member so that the cutting edge comes into pressure contact with the guide part.

一方の刃物には、他方の刃物の切り始め側及び切り終り側に該刃物をガイドするガイド部が設けられている。これにより、両刃物の刃先は平行に保持される。このため、例えば押さえローラが無くても板状部材を引っ込む力が発生しなく、真っ直ぐに切断できる。また特に、板状部材が軟質材で従来では押さえても切り終り側が真っ直ぐにならないものに対して効果絶大である。 One blade is provided with a guide portion for guiding the blade on the cutting start side and the cutting end side of the other blade. As a result, the cutting edges of both blades are held in parallel. For this reason, for example, even if there is no pressing roller, a force for retracting the plate-like member is not generated, and it can be cut straight. Further, the effect is particularly great for a plate-like member that is a soft material and does not become straight at the end of cutting even if it is conventionally pressed.

本発明の板状部材用カッターの一実施の形態を図１により説明する。なお、図３と同じ又は相当部材には同一符号を付し、その詳細な説明は省略する。固定刃物２０には、移動刃物１０の切り終り側１３側にもガイド部２３が設けられている。 One embodiment of the cutter for plate-like members of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same or equivalent member as FIG. The fixed blade 20 is also provided with a guide portion 23 on the cutting end side 13 side of the movable blade 10.

このように、固定刃物２０には、移動刃物１０の切り始め側１２及び切り終り側１３に移動刃物１０をガイドするガイド部２２、２３が設けられていると共に、従来と同様に、移動刃物１０及び固定刃物２０には逃げ角θ１及びθ２が設けられている。即ち、ガイド部２２、２３と両刃物１０、２０に逃げ角θ１、θ２を有することにより、刃先１１と２１とは平行に保持され、かつクリアランスが０に保たれる。このため、図４（ａ）に示すように押さえローラ４２、４３が無くても板状部材Ｗを引っ込む力が発生しなく、真っ直ぐに切断できる。即ち、図４（ｂ）に示すように、押さえローラ４２、４３を設けてもよいが、単に送りローラ４０、４１のみでもよい。特に、本実施の形態においては、板状部材Ｗが軟質材で従来では押さえても切り終り側１３が真っ直ぐにならないものに対して効果絶大である。 As described above, the fixed blade 20 is provided with the guide portions 22 and 23 for guiding the moving blade 10 on the cutting start side 12 and the cutting end side 13 of the moving blade 10, and the moving blade 10 is provided in the same manner as in the prior art. The fixed blade 20 has clearance angles θ1 and θ2. That is, since the guide portions 22 and 23 and the two blades 10 and 20 have clearance angles θ1 and θ2, the blade edges 11 and 21 are held in parallel and the clearance is kept at zero. For this reason, as shown in FIG. 4A, a force for retracting the plate-like member W does not occur even if the pressing rollers 42 and 43 are not provided, and can be cut straight. That is, as shown in FIG. 4B, the pressing rollers 42 and 43 may be provided, but only the feeding rollers 40 and 41 may be provided. In particular, in the present embodiment, the effect is tremendous for the plate-like member W that is a soft material and does not become straight at the cutting end side 13 even if it is conventionally pressed.

図２は本発明の板状部材用カッターの他の実施の形態を示す。前記実施の形態においては、固定刃物２０にガイド部２２、２３を設けたが、本実施の形態は、移動刃物１０にガイド部１５、１６を設けた。このように構成しても、前記実施の形態と同様に、刃先１１と２１とは平行に保持されるので、前記実施の形態と同様の効果が得られる。 FIG. 2 shows another embodiment of the cutter for plate-like member of the present invention. In the embodiment described above, the guide portions 22 and 23 are provided on the fixed blade 20, but in the present embodiment, the guide portions 15 and 16 are provided on the movable blade 10. Even if comprised in this way, since the blade edge | tips 11 and 21 are hold | maintained in parallel like the said embodiment, the effect similar to the said embodiment is acquired.

上記実施の形態においては、ガイド部２２、２３は固定刃物２０に設けたが、固定刃物２０が固定された図示しないベース板部に固定してもよい。また傾斜した刃先１１が形成された移動刃物１０を移動させ、水平な刃先２１が形成された固定刃物２０を固定した場合について説明したが、傾斜した刃先１１が形成された移動刃物１０を固定し、水平な刃先２１が形成された固定刃物２０を移動させてもよい。要は、相対向して配設された第１刃物と第２刃物を相対的に移動させる構造であればよい。 In the above embodiment, the guide portions 22 and 23 are provided on the fixed blade 20, but may be fixed to a base plate (not shown) to which the fixed blade 20 is fixed. Moreover, although the case where the movable blade 10 with the inclined blade edge 11 is moved and the fixed blade 20 with the horizontal blade edge 21 is fixed has been described, the movable blade 10 with the inclined blade edge 11 is fixed. The fixed blade 20 on which the horizontal blade edge 21 is formed may be moved. In short, any structure may be used as long as the first cutter and the second cutter arranged to face each other are relatively moved.
