Description

本発明は、樹脂材および段ボールを切断して建材等に使用される様々な製品を切り出すための切断刃および切断装置に関する。 The present invention relates to a cutting blade and a cutting device for cutting various products used for building materials and the like by cutting resin materials and corrugated cardboard.

ポリウレタンフォーム、ポリエチレンフォーム、フェノールフォーム等の発泡樹脂は、断熱材として広く使用され、省エネルギー化や建物の居住性向上に欠かせない材料として知られている。しかし、発泡樹脂を切断加工しようとすると、大量の粉じんが発生して作業環境を悪化させ、健康被害も懸念される。また、多くの発泡樹脂は可燃性であるため、これらに引火すると燃焼が拡大する危険性があり、難燃化等の対応策を講じているものの火災事故が未だに報告されている。さらに、発泡樹脂は弾性を有し、摩擦抵抗が大きいため、例えば100mm以上の厚さの発泡樹脂をナイフ状の切断刃を用いて切断しようとすると、切断刃の側面に発泡樹脂の切断面が密着して切り進むことが難しい。 Foaming resins such as polyurethane foam, polyethylene foam, and phenol foam are widely used as heat insulating materials, and are known as indispensable materials for energy saving and improvement of livability of buildings. However, when the foamed resin is cut and processed, a large amount of dust is generated, which deteriorates the working environment and may cause health problems. In addition, since many foamed resins are flammable, there is a risk that combustion will expand if they catch fire, and although measures such as flame retardancy have been taken, fire accidents have still been reported. Further, since the foamed resin has elasticity and high frictional resistance, for example, when trying to cut a foamed resin having a thickness of 100 mm or more using a knife-shaped cutting blade, the cut surface of the foamed resin is formed on the side surface of the cutting blade. It is difficult to get in close contact with each other.

従来から、発泡樹脂を切断する装置として、特許文献1に記載されている電熱線による溶融切断装置や、特許文献2に記載されているループ状の線状刃を有する切断装置や、特許文献3に記載されている直線状の細線を有する切断機がある。 Conventionally, as a device for cutting a foamed resin, a melt cutting device using a heating wire described in Patent Document 1, a cutting device having a loop-shaped linear blade described in Patent Document 2, and Patent Document 3 have been used. There is a cutting machine having a straight thin line described in.

しかしながら、特許文献1~3のような従来の切断装置は、被切断物との接触面積が小さく、摩擦抵抗は少ないものの、電熱線や線状刃の撓み等に起因した加工精度の問題や、切断面の凹凸等の外観の問題があった。また、同様の問題は段ボールシートの切断においてもあった。 However, although the conventional cutting devices such as Patent Documents 1 to 3 have a small contact area with the object to be cut and a small frictional resistance, there are problems in processing accuracy due to bending of the heating wire and the linear blade, and the like. There was a problem of appearance such as unevenness of the cut surface. A similar problem was also found in the cutting of corrugated board sheets.

These explanatory diagrams are schematically drawn by omitting them as appropriate for the sake of clarity.

本発明に係る切断刃1~5は樹脂材または段ボール(以下、被切断物という)Wを切断するためのものである。尚、本発明の切断対象である樹脂材Wとしては、発泡樹脂材、非発泡樹脂材等が考えられる。発泡樹脂材としては、例えば、発泡ポリウレタン、発泡ポリエチレン、発泡ポリプロピレン、フェノールフォーム等が挙げられる。また、樹脂材Wは、発泡樹脂材、非発泡樹脂材等からなる層と石膏等の他の材料からなる層とを積層した複合材も含むものであり、形状については、板状だけでなく、より厚みのある直方体状や、立方体状、球状、楕円形状等、任意である。段ボールWは、紙、プラスチックフィルム等から成り、段ボールシート1枚だけでなく、複数枚のシートが積み重ねられたものでもよい。 The cutting blades 1 to 5 according to the present invention are for cutting a resin material or a corrugated cardboard (hereinafter referred to as a material to be cut) W. As the resin material W to be cut in the present invention, a foamed resin material, a non-foamed resin material, or the like can be considered. Examples of the foamed resin material include polyurethane foam, polyethylene foam, polypropylene foam, phenol foam and the like. Further, the resin material W also includes a composite material in which a layer made of a foamed resin material, a non-foamed resin material, or the like and a layer made of another material such as gypsum are laminated, and the shape is not limited to a plate shape. , Thicker rectangular parallelepiped, cubic, spherical, elliptical, etc. are optional. The corrugated cardboard W is made of paper, a plastic film, or the like, and is not limited to one corrugated cardboard sheet, but may be a stack of a plurality of sheets.

図1、2、6~8に示すように切断刃1~5は、基部10、40と刃部30、60、62とを備えている。尚、切断刃3~5は、実施例2の変形例であるため切断刃2と同じ符号を用いる。基部10、40は、略三角形状の薄板からなる。ここで、本発明において略三角形状とは、3辺に囲まれた厳密な三角形だけでなく、2辺が交わり形成される三角形の3つの頂部のうち少なくとも1つを欠くものも含むものである。例えば、図1のように2つの頂部を欠くものや、図2のように3つの頂部全てを欠くものも含まれる。また、略三角形状には、角が丸みを帯びたものも含まれる。 As shown in FIGS. 1, 2, 6 to 8, the cutting blades 1 to 5 include bases 10, 40 and blades 30, 60, 62. Since the cutting blades 3 to 5 are modifications of the second embodiment, the same reference numerals as those of the cutting blade 2 are used. The bases 10 and 40 are made of a substantially triangular thin plate. Here, in the present invention, the substantially triangular shape includes not only a strict triangle surrounded by three sides but also a triangle lacking at least one of three tops of a triangle formed by intersecting two sides. For example, the one lacking two tops as shown in FIG. 1 and the one lacking all three tops as shown in FIG. 2 are also included. In addition, the substantially triangular shape includes those with rounded corners.

刃部30、60、62は、略三角形状の基部10、40の外端の第一の斜辺12、42および/または第二の斜辺44に、延在するように形成された両刃である。つまり、略三角形状の薄板の輪郭を構成する3辺のうちの1辺である第一の斜辺12のみに、刃部30が形成されている、または、3辺のうちの2辺である第一の斜辺42と第二の斜辺44に、刃部60と刃部62がそれぞれ形成されている。 The blade portions 30, 60, 62 are double-edged blades formed so as to extend to the first hypotenuse 12, 42 and / or the second hypotenuse 44 at the outer end of the substantially triangular base 10, 40. That is, the blade portion 30 is formed only on the first hypotenuse 12, which is one of the three sides constituting the contour of the substantially triangular thin plate, or the second side of the three sides. A blade portion 60 and a blade portion 62 are formed on the first hypotenuse 42 and the second hypotenuse 44, respectively.

切断刃1~5をこのような構成にすることによって、切断の際、被切断物Wをスムーズに切り進むことができ、切断刃1~5の切断能力、加工速度の向上を図ることができる。また、基部10、40が略三角形状であるため、切断の際の刃部30、60、62のたわみを防止し安定して切り進むことができ、加工精度を向上することができ、切断刃1~5の刃先がナイフ状の両刃になっており、被切断物Wを切り裂くことで粉じんの発生を抑制することができる。 By making the cutting blades 1 to 5 have such a configuration, it is possible to smoothly cut the object W to be cut at the time of cutting, and it is possible to improve the cutting ability and the processing speed of the cutting blades 1 to 5. .. Further, since the bases 10 and 40 have a substantially triangular shape, it is possible to prevent the blades 30, 60 and 62 from bending at the time of cutting, to stably cut, and to improve the processing accuracy, and the cutting blade. The cutting edges of 1 to 5 are knife-shaped double-edged blades, and the generation of dust can be suppressed by cutting the object W to be cut.

図2に示すように、切断刃2の基部40は、貫通穴である窓部70を有していてもよい。窓部70は、薄板である基部40の表裏面を貫通した穴であれば、形状、大きさ、位置、数は特に限定されるものではないが、形状は、略三角形状、略台形状、略矩形状、略楕円状、略円状またはそれらを組み合わせた形状等が考えられる。図2、3に示すように、窓部70は刃部60と刃部62に挟まれた、被切断物Wと接触する部分に設けられていることが好ましい。 As shown in FIG. 2, the base 40 of the cutting blade 2 may have a window 70 which is a through hole. The shape, size, position, and number of the window portion 70 are not particularly limited as long as they are holes penetrating the front and back surfaces of the base portion 40 which is a thin plate, but the shape is substantially triangular or substantially trapezoidal. A substantially rectangular shape, a substantially elliptical shape, a substantially circular shape, or a combination thereof can be considered. As shown in FIGS. 2 and 3, the window portion 70 is preferably provided at a portion sandwiched between the blade portion 60 and the blade portion 62 and in contact with the object to be cut W.

また、窓部70は1つであっても、複数個であってもよく、図6~8に示すように窓部70がその一部に架橋部72を備えていることにより複数個に分割されたものであってもよい。架橋部72の形状、配置、大きさは任意であり、図6~8に示すようなものに限定されるものではない。 Further, the window portion 70 may be one or a plurality, and as shown in FIGS. 6 to 8, the window portion 70 is divided into a plurality of portions because the window portion 70 is partially provided with the cross-linking portion 72. It may be the one that has been done. The shape, arrangement, and size of the cross-linking portion 72 are arbitrary, and are not limited to those shown in FIGS. 6 to 8.

切断刃2~5の基部40は、貫通穴である窓部70を有していることによって、切断の際、被切断物Wの切断面と切断刃2~5との接触による抵抗を簡単な構造で低減することが可能となり、被切断物Wをスムーズに切り進むことができる。 Since the base 40 of the cutting blades 2 to 5 has a window portion 70 which is a through hole, resistance due to contact between the cut surface of the object to be cut W and the cutting blades 2 to 5 during cutting is simple. The structure can be reduced, and the object W to be cut can be smoothly cut.

また、切断刃1~5は、基部10、40の厚さが0.80mmを含む0.35mm~1.00mmであることが好ましい。この範囲であれば、切断刃1~5の強度を確保しながら、被切断物Wをスムーズに切り進むことができる。切断刃1~5の基部10、40の厚さは、切断しようとする被切断物Wの種類、厚さにより適宜選択することが好ましい。例えば、樹脂材の場合は0.60mm~0.85mm、段ボールの場合は0.40mm~0.90mmの範囲であることがより好ましい。 Further, the cutting blades 1 to 5 preferably have a thickness of the bases 10 and 40 of 0.35 mm to 1.00 mm including 0.80 mm. Within this range, the object W to be cut can be smoothly cut while ensuring the strength of the cutting blades 1 to 5. It is preferable that the thicknesses of the bases 10 and 40 of the cutting blades 1 to 5 are appropriately selected depending on the type and thickness of the object to be cut W to be cut. For example, in the case of a resin material, it is more preferably in the range of 0.60 mm to 0.85 mm, and in the case of corrugated cardboard, it is more preferably in the range of 0.40 mm to 0.90 mm.

基部10、40は、第一の斜辺12、42および第二の斜辺14、44を含む本体部18、48と、切断刃1~5自体を固定または把持するための、底辺16、46を含む固定部20、50とからなる。図1に示すような本体部18の第一の斜辺12および第二の斜辺14の成す角度α、または、図2に示すような本体部48の第一の斜辺42および第二の斜辺44の各延長線の成す角度βは、80度、90度を含む60度~120度であることが好ましい。 The bases 10 and 40 include body portions 18, 48 including the first hypotenuse 12, 42 and the second hypotenuse 14, 44, and bottoms 16, 46 for fixing or gripping the cutting blades 1 to 5 themselves. It consists of fixing portions 20 and 50. The angle α formed by the first hypotenuse 12 and the second hypotenuse 14 of the main body 18 as shown in FIG. 1, or the first hypotenuse 42 and the second hypotenuse 44 of the main body 48 as shown in FIG. The angle β formed by each extension line is preferably 60 to 120 degrees including 80 degrees and 90 degrees.

基部40の本体部48の外端から窓部70の縁までの幅a、bは20mm~60mmであることが、切断刃2~5の強度を確保する観点から好ましい。尚、基部40の本体部48の外端から窓部70の縁までの幅とは、基部40の本体部48の外端から最も近い窓部70の縁、つまり最も近い貫通穴の端面、までの距離を測定した値である。 The widths a and b from the outer end of the main body 48 of the base 40 to the edge of the window 70 are preferably 20 mm to 60 mm from the viewpoint of ensuring the strength of the cutting blades 2 to 5. The width from the outer end of the main body 48 of the base 40 to the edge of the window 70 is from the outer end of the main body 48 of the base 40 to the edge of the nearest window 70, that is, the end face of the nearest through hole. It is a value measured by the distance of.

基部40の窓部70は略三角形状であることが好ましく、略二等辺三角形状であることが特に好ましい。本体部48および窓部70が共に同形状の略二等辺三角形状である場合、基部40の本体部48の外端から窓部70の縁までの第一の斜辺42側の幅aと第二の斜辺44側の幅bとを等しくすることが好ましい。 The window portion 70 of the base portion 40 preferably has a substantially triangular shape, and particularly preferably has a substantially isosceles triangle shape. When both the main body 48 and the window 70 have a substantially isosceles triangle shape of the same shape, the width a on the first hypotenuse side 42 from the outer end of the main body 48 of the base 40 to the edge of the window 70 and the second It is preferable to make the width b on the hypotenuse 44 side of the above equal to that of.

図2に示すように、切断刃2~5は、基部40の本体部48の第一の斜辺42および第二の斜辺44のそれぞれに刃部60、62を備えていてもよい。2つの刃部60、62を備えた切断刃2~5を用いて被切断物Wを切断する場合、前進した際にも後進した際にも切断することが可能となる。また、前進した際に切断した被切断物Wを動かさずに、切断後に互いに密着した切断面の間を後進してスタート位置に戻ることも可能であるため作業効率が上がる。 As shown in FIG. 2, the cutting blades 2 to 5 may be provided with blade portions 60 and 62 on the first hypotenuse 42 and the second hypotenuse 44 of the main body 48 of the base 40, respectively. When the object W to be cut is cut by using the cutting blades 2 to 5 provided with the two blade portions 60 and 62, it is possible to cut the object W both when moving forward and when moving backward. Further, since it is possible to move backward between the cut surfaces in close contact with each other after cutting without moving the cut object W when moving forward, the work efficiency is improved.

尚、本発明では、切断刃1~5が被切断物Wに向かって、または、被切断物Wが切断刃1~5に向かって、切断するために一定の方向に移動することを前進とし、切断刃1~5または被切断物Wが前進した一定の方向とは反対方向に戻るように移動することを後進とする。 In the present invention, the advance is that the cutting blades 1 to 5 move toward the object W to be cut, or the object W to be cut moves toward the cutting blades 1 to 5 in a certain direction for cutting. The reverse movement is such that the cutting blades 1 to 5 or the object to be cut W move in the direction opposite to the fixed direction in which the cutting blade W has advanced.

切断刃1~5の素材は、高速度工具鋼鋼材、または、炭素工具鋼鋼材であることが好ましい。これにより、被切断物Wの切断に十分な強度を確保することができる。 The material of the cutting blades 1 to 5 is preferably a high-speed tool steel material or a carbon tool steel material. This makes it possible to secure sufficient strength for cutting the object W to be cut.

本発明に係る切断装置100は、上述した本発明に係る切断刃1~5を備えた、樹脂材または段ボールといった被切断物Wを切断するための装置である。図4は、切断刃2が矢印の示す方向に被切断物Wに対して前進することを、図5は、切断刃2が矢印の示す方向に被切断物Wに対して後進することを示している。尚、被切断物Wが移動機構112により移動する場合には、被切断物Wが前進および後進する方向は、それぞれ図4および図5の矢印が示す方向とは反対になる。 The cutting device 100 according to the present invention is a device provided with the above-mentioned cutting blades 1 to 5 according to the present invention for cutting an object W to be cut such as a resin material or corrugated cardboard. FIG. 4 shows that the cutting blade 2 advances with respect to the object W to be cut in the direction indicated by the arrow, and FIG. 5 shows that the cutting blade 2 advances with respect to the object W to be cut in the direction indicated by the arrow. ing. When the object to be cut W is moved by the moving mechanism 112, the directions in which the object to be cut W moves forward and backward are opposite to the directions indicated by the arrows in FIGS. 4 and 5, respectively.

図4および図5に示すように、切断装置100は、上述した切断刃2と、被切断物Wを載置するための加工台110と、切断刃2を被切断物Wに対して前進させる前後進行(往復移動)可能な移動機構112とを備えている。切断装置100は、切断刃2が基部40の本体部48の第一の斜辺42または第二の斜辺44を進行方向に向けて立設されるように、固定部50が移動機構112に保持されている。尚、移動機構112は、切断刃2の代わりに被切断物Wを、切断刃2に対して前後進行させることが可能なものであってもよい。切断装置100は、切断刃1~5が固定された移動機構112を前進または後進させることにより、加工台110に載置した被切断物Wを、スムーズに切り進むことができる。 As shown in FIGS. 4 and 5, the cutting device 100 advances the cutting blade 2 described above, the processing table 110 on which the object W to be cut is placed, and the cutting blade 2 with respect to the object W to be cut. It is equipped with a moving mechanism 112 capable of moving forward and backward (reciprocating movement). In the cutting device 100, the fixing portion 50 is held by the moving mechanism 112 so that the cutting blade 2 is erected with the first hypotenuse 42 or the second hypotenuse 44 of the main body 48 of the base 40 facing the traveling direction. ing. The moving mechanism 112 may be capable of moving the object to be cut W back and forth with respect to the cutting blade 2 instead of the cutting blade 2. The cutting device 100 can smoothly cut the object to be cut W placed on the processing table 110 by moving the moving mechanism 112 to which the cutting blades 1 to 5 are fixed forward or backward.
