Abstract

<P>PROBLEM TO BE SOLVED: To provide a cutting blade capable of preventing a rise in temperature of the cutting blade on a cutting part and preventing adhesion of laminated sheet materials. <P>SOLUTION: The cutting blade 1 is equipped with a groove 10 on a body 5. The groove 10 has a part 11 with a constant depth, which opens on the other side of the blade 1, that is, on the backside thereof, and an upper end 12 and a lower end 13 with their depths varying on both sides. Since a material is cut while the material to be cut is fixed onto a cutting table by sucking the material from under the table for mounting the material in an automatic cutting machine, the suction air passes through the groove 10 for efficient cooling. Since the groove 10 opens on the backside of the cutting blade 1, it does not come in contact with the material to be cut, thereby securing a passage of the suction air. By providing the groove 10 on the backside of the cutting blade 1, a heat releasing area of the blade 10 increases, a distance between a heat dissipating surface and a heat generating part is shortened, and efficient cooling can be performed. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、シート材を積層状態で裁断する自動裁断機などに使用する裁断刃に関する。   The present invention relates to a cutting blade used in an automatic cutting machine or the like that cuts sheet materials in a laminated state.

従来から、裁断テーブル上に積層状態のシート材を保持しながら、予め設定されるデータに従ってシート材を裁断する自動裁断機には、上下動させる裁断刃を備える形式のものが広く使用されている（たとえば、特許文献１参照。）。裁断刃は、裁断テーブルの表面に沿って二次元的に移動可能な裁断ヘッドから垂下して、積層状態のシート材を貫通しながら、楔形断面形状の一側方に設けられる刃先側でシート材を裁断する。裁断刃の刃先や、刃先に隣接する側面は、シート材に密着する状態で上下動し、摩擦熱を発生する。摩擦熱の発生量が多くなると、裁断刃の周囲のシート材の温度が上昇する。シート材として、ナイロンやポリエステル等の合成繊維材料や、糊付の芯地などが使用される場合、裁断箇所が溶着するおそれがある。裁断箇所が溶着すると、積層状態のシート材を、個々のシート材に分離することが困難になったり、さらには不可能になったりする。 2. Description of the Related Art Conventionally, an automatic cutting machine that cuts a sheet material in accordance with preset data while holding a laminated sheet material on a cutting table has been widely used in a type having a cutting blade that moves up and down. (For example, refer to Patent Document 1). The cutting blade hangs down from the cutting head that can move two-dimensionally along the surface of the cutting table and penetrates the laminated sheet material, while the sheet material is provided on one side of the wedge-shaped cross-section. Is cut. The cutting edge and the side surface adjacent to the cutting edge move up and down in close contact with the sheet material and generate frictional heat. When the amount of generated frictional heat increases, the temperature of the sheet material around the cutting blade increases. When a synthetic fiber material such as nylon or polyester, a glued interlining, or the like is used as the sheet material, the cut portion may be welded. When the cut portion is welded, it becomes difficult or even impossible to separate the laminated sheet material into individual sheet materials.

特許文献１に開示されている裁断刃は、刃先が両側に平面状の切刃面を伴う裁断刃先頭部となり、大略的に楔形の断面形状を有する。断面形状の側面には、切刃面と本体部分との間で、凹部が形成される。凹部を設けることによって、裁断刃の剛性を低下させることなく、被研磨部の体積を小さくして、研磨時間の短縮や裁断時の抵抗の緩和を図ることができる。裁断中のシート材を保持するための吸引作用を受けて、凹部を通って外部からの空気が流入し、裁断の際に摩擦で発熱する部分を冷却し、シート材同士の溶着を防ぐような効果を有することが期待される旨も記載されている。 The cutting blade disclosed in Patent Document 1 has a cutting edge leading portion with a flat cutting edge surface on both sides, and has a substantially wedge-shaped cross-sectional shape. A recess is formed on the side surface of the cross-sectional shape between the cutting edge surface and the main body portion. By providing the concave portion, the volume of the portion to be polished can be reduced without reducing the rigidity of the cutting blade, so that the polishing time can be shortened and the resistance during cutting can be reduced. Under the suction action to hold the sheet material being cut, air from the outside flows through the recess, cools the part that generates heat due to friction during cutting, and prevents welding of the sheet materials It is also described that it is expected to have an effect.

裁断刃となる衝撃カッタを支持する支持部材内に冷却路を設けて、冷却路に冷風を導入して衝撃カッタおよび支持部材を冷却する扁平材料用裁断機も開示されている（たとえば、特許文献２参照。）。また、裁断刃を中空に形成し、側面に中空部分に連通する孔を設けて、中空部分に冷気を供給して孔から放出させ、裁断部分を冷却する布地裁断中空多孔刃も開示されている（たとえば、特許文献３参照。）。さらに、布裁断ナイフの側面に凹凸部を設ける技術も開示されている（たとえば、特許文献４参照。）。特許文献４の明細書には、往復動に伴う空気の流れで、生地と接触しなくなって溶着が生じなくなる旨も記載されている。
特開平５−８４６９３号公報 特開昭６２−２１３９９４号公報 特開２０００−４２９９２号公報 実開平２−１０７４８７号公報 A flat material cutting machine is also disclosed in which a cooling path is provided in a support member that supports an impact cutter serving as a cutting blade, and cool air is introduced into the cooling path to cool the impact cutter and the support member (for example, Patent Documents). 2). Also disclosed is a fabric-cut hollow perforated blade in which a cutting blade is formed hollow, a hole communicating with the hollow portion is provided on a side surface, cool air is supplied to the hollow portion and discharged from the hole, and the cutting portion is cooled. (For example, see Patent Document 3). Furthermore, the technique which provides an uneven | corrugated | grooved part in the side surface of the cloth cutting knife is also disclosed (for example, refer patent document 4). The specification of Patent Document 4 also describes that welding does not occur due to the flow of air accompanying the reciprocating motion and no longer in contact with the fabric.

特許文献１のように、切刃面から本体部の間に凹部を設ける構成では、被研磨部の体積を小さくして研磨時間を短縮し、裁断時の抵抗を緩和する効果は充分にあるけれども、凹部を通る空気による冷却は充分ではない。特に、特許文献１の図７に示すように、裁断刃が被裁断材に突入して上下動しながら進行すれば、切り裂いた被裁断材の生地面が裁断刃の凹部を含む斜面に沿って密着するので、凹部からの空気の流入は少なくなる。凹部を大きくすれば、空気の流入を多くすることができるけれども、裁断刃としての剛性が低下するので、限界がある。   As in Patent Document 1, the configuration in which the concave portion is provided between the cutting edge surface and the main body has a sufficient effect of reducing the polishing time by reducing the volume of the portion to be polished and reducing the resistance at the time of cutting. Cooling with air passing through the recess is not sufficient. In particular, as shown in FIG. 7 of Patent Document 1, if the cutting blade enters the material to be cut and moves while moving up and down, the material surface of the material to be cut along the slope including the concave portion of the cutting blade. Since it adheres, the inflow of air from a recessed part decreases. If the recess is made larger, the inflow of air can be increased, but there is a limit because the rigidity as the cutting blade is lowered.

特許文献２では、裁断刃を支持部材で支持する部分を冷却することはできても、被裁断材である積層されたシート材の上方での冷却となり、被裁断材の内部や裁断刃先端部の裁断部分へは冷風を流すことはできない。特許文献３のように、裁断刃を中空に形成することは、加工が困難で製造コストが上昇してしまう。特許文献４のように、空気の流れを発生させるための凹凸を側面に形成する布裁断ナイフも、凹部を形成する場合は剛性が低下し、凸部を形成する場合は加工が困難で製造コストが上昇してしまうと考えられる。 In Patent Document 2, although the portion of the cutting blade that is supported by the support member can be cooled, cooling is performed above the laminated sheet material that is the material to be cut, and the inside of the material to be cut and the tip of the cutting blade Cold air cannot flow to the cut part of As in Patent Document 3, it is difficult to form the cutting blade in a hollow state, and the manufacturing cost increases. As in Patent Document 4, the cloth cutting knife for forming the unevenness for generating the air flow on the side surface also has a reduced rigidity when forming the concave portion, and is difficult to process when forming the convex portion, resulting in a manufacturing cost. Will rise.

本発明の目的は、裁断部分での裁断刃の温度上昇を抑え、積層されたシート材の溶着を防止することが可能な裁断刃を提供することである。   The objective of this invention is providing the cutting blade which can suppress the temperature rise of the cutting blade in a cutting part, and can prevent the welding of the laminated | stacked sheet | seat material.

本発明は、楔形断面を有する直刀状で、テーブル上に載置される積層されたシート材に上方から貫通させ、往復動しながら楔形断面の一側方に形成される刃先でシート材を裁断する裁断刃において、
該楔形断面の他側方に開口する溝を、該刃先でシート材を裁断する部分の範囲内で、該楔形断面の内部に有することを特徴とする裁断刃である。 The present invention is a straight blade having a wedge-shaped cross section, penetrates a laminated sheet material placed on a table from above, and uses a blade edge formed on one side of the wedge-shaped cross section while reciprocating. In the cutting blade to cut,
A cutting blade characterized in that a groove opening on the other side of the wedge-shaped cross section is provided inside the wedge-shaped cross section within a range of a portion where the sheet material is cut by the blade edge.

また本発明で、前記楔形断面は、前記他側方側に、厚みが一定の部分を有し、
前記溝は、該厚みが一定の部分内に形成されていることを特徴とする。 In the present invention, the wedge-shaped cross section has a portion having a constant thickness on the other side,
The groove is formed in a portion having a constant thickness.

また本発明で、前記溝は、前記往復動しながらシート材を裁断する部分の範囲が一定の深さに形成され、該範囲の上端では深さが該範囲から離れるに伴って深さが減少するように形成されていることを特徴とする。   In the present invention, the groove is formed to have a constant depth in a portion where the sheet material is cut while reciprocating, and the depth decreases at the upper end of the range as the depth moves away from the range. It is formed so that it may do.

本発明によれば、楔形断面の一側方に形成される刃先でシート材を裁断する裁断刃の楔形断面の内部に、他側方に開口する溝を有するので、溝に空気などが流れれば、裁断刃を楔形断面の内部から冷却することができる。溝は、少なくとも裁断刃がシート材を裁断する部分の範囲内に有するので、溝を流れる空気で裁断刃の楔形断面の内部から冷却し、裁断刃の温度を低下させて、裁断部分での積層されたシート材への溶着を防止することができる。溝は、楔形断面の他側方に開口しているので、裁断刃の他側方からの切削加工などで、容易に形成することができる。 According to the present invention, since the wedge-shaped cross section of the cutting blade that cuts the sheet material with the blade edge formed on one side of the wedge-shaped cross section has the groove that opens to the other side, air or the like flows through the groove. For example, the cutting blade can be cooled from the inside of the wedge-shaped cross section. Since the groove has at least the range of the part where the cutting blade cuts the sheet material, the air flowing through the groove is cooled from the inside of the wedge-shaped section of the cutting blade, the temperature of the cutting blade is lowered, and the lamination at the cutting part It is possible to prevent welding to the sheet material. Since the groove opens to the other side of the wedge-shaped cross section, it can be easily formed by cutting from the other side of the cutting blade.

また本発明によれば、溝は楔形断面で厚みが一定の部分の内部に形成されるので、楔形断面の一側方の刃先部分を研磨しても、溝は研磨に影響しないようにすることができる。 Further, according to the present invention, since the groove is formed inside the portion having a constant wedge-shaped cross section, the groove does not affect the polishing even if the cutting edge portion on one side of the wedge-shaped cross section is polished. Can do.

また本発明によれば、溝は、往復動しながらシート材を裁断する範囲の上端は深さが範囲から離れるに伴って減少するように形成されているので、裁断刃の強度が急変することはなく、裁断くずの抜けも良くすることができる。往復動でシート材を裁断する部分の範囲では、溝は一定の深さに形成されるので、範囲外で溝に流入させた空気を円滑に流通させ、溝の内壁を通して裁断刃の表面で発生する熱を除去することができる。溝は、一定の深さのみに形成するよりも、少なくとも上端では深さが減少するように形成する方が加工も容易となる。 Further, according to the present invention, the groove is formed so that the upper end of the range where the sheet material is cut while reciprocating decreases as the depth goes away from the range, so that the strength of the cutting blade changes abruptly. There is no, and the omission of cutting waste can be improved. In the range of the part where the sheet material is cut by reciprocating motion, the groove is formed at a certain depth, so the air that has flowed into the groove outside the range flows smoothly and is generated on the surface of the cutting blade through the inner wall of the groove Heat to be removed. Rather than forming the groove only at a certain depth, it is easier to process the groove so that the depth is reduced at least at the upper end.

図１は、本発明の実施の一形態としての裁断刃１の基本的な構成を示す。裁断刃１は、直刃状で、先端には押切刃２を有し、一側方に裁断刃先頭部３を有する。押切刃２は、被裁断材の表面から突刺すために使用する。被裁断材に突刺した後は、裁断刃先頭部３が上下動して被裁断材を裁断する。裁断刃先頭部３を頂部とする裁断刃１の両側面には、切刃面４がそれぞれ設けられる。裁断刃１で、裁断刃先頭部３の峰側は、本体部５となっている。本体部５と切刃面４との間には、特許文献１に記載されているような凹部６が設けられる。ここまでの裁断刃１の構成は、特許文献１に記載されている裁断刃と同等である。なお、裁断刃１の上部は記載を省略しているけれども、上下駆動を行う機構への連結部分が形成される。   FIG. 1 shows a basic configuration of a cutting blade 1 as an embodiment of the present invention. The cutting blade 1 has a straight blade shape, has a cutting blade 2 at the tip, and has a cutting blade leading portion 3 on one side. The pressing blade 2 is used for piercing from the surface of the material to be cut. After piercing the material to be cut, the cutting blade head 3 moves up and down to cut the material to be cut. Cutting blade surfaces 4 are provided on both side surfaces of the cutting blade 1 with the cutting blade leading portion 3 as the top. In the cutting blade 1, the ridge side of the cutting blade leading portion 3 is a main body portion 5. A recess 6 as described in Patent Document 1 is provided between the main body 5 and the cutting edge surface 4. The structure of the cutting blade 1 so far is equivalent to the cutting blade described in Patent Document 1. In addition, although description is abbreviate | omitted for the upper part of the cutting blade 1, the connection part to the mechanism which performs an up-down drive is formed.

図１の裁断刃１には、本体部５に、溝１０が設けられる。溝１０は、裁断刃１の他側方、すなわち峰側に開口し、深さが一定である深さ一定部１１と、その両端で深さが変化する上端部１２および下端部１３とを有する。深さ一定部１１は、裁断刃先頭部３および切刃面４のうち、上下方向の往復動で被裁断材を実際に裁断する範囲に対応して設けられている。上端部１２および下端部１３のような深さの変化は、溝１０をディスク状の切削具で切削して形成する場合に、容易に付加することができる。深さ一定部１１を下端まで延長して、下端部１３を設けないようにすることもできる。 The cutting blade 1 of FIG. 1 is provided with a groove 10 in the main body 5. The groove 10 has a constant depth portion 11 that opens to the other side of the cutting blade 1, that is, the peak side, and has a constant depth, and an upper end portion 12 and a lower end portion 13 that change in depth at both ends thereof. . The constant depth portion 11 is provided corresponding to a range in which the material to be cut is actually cut by the reciprocating motion in the vertical direction in the cutting blade leading portion 3 and the cutting blade surface 4. Changes in depth such as the upper end 12 and the lower end 13 can be easily added when the groove 10 is formed by cutting with a disk-shaped cutting tool. The constant depth portion 11 can be extended to the lower end so that the lower end portion 13 is not provided.

図２は、図１の裁断刃１および他の実施形態の裁断刃２１の断面形状を示す。図２（ａ）および（ｄ）は、溝１０の深さ一定部１１が形成されている部分の断面形状を示す。裁断刃１、２１の断面形状は、大略的に裁断刃先頭部３を頂部とする楔形形状であり、本体部５は一定の幅ｔを有する。本体部５と裁断刃先頭部３との間の両切刃面４は、裁断部先頭部３側で対向する間隔が狭まるように傾斜している。裁断刃１，２１の裁断刃先頭部３と本体部５の背面との間隔Ｌは、５〜１０ｍｍ程度である。本体部５の幅ｔは、２〜３ｍｍ程度である。本体部５の高さＡは、２〜４ｍｍ程度であり、幅ｔよりは大きくする。深さ一定部１１での溝の深さは、たとえば本体部５の高さＡの６０〜８０％程度とする。溝１０の幅は、本体部５の幅ｔの３０〜５０％程度とする。溝の幅および深さを、本体部５の幅ｔおよび高さＡに比較して小さくするのは、本体部５の剛性を保つためである。 FIG. 2 shows a cross-sectional shape of the cutting blade 1 of FIG. 1 and the cutting blade 21 of another embodiment. 2A and 2D show a cross-sectional shape of a portion where the constant depth portion 11 of the groove 10 is formed. The cross-sectional shapes of the cutting blades 1 and 21 are generally wedge-shaped with the cutting blade leading portion 3 as the top, and the main body portion 5 has a constant width t. Both cutting blade surfaces 4 between the main body 5 and the cutting blade leading portion 3 are inclined so that the distance between them facing the cutting portion leading portion 3 is narrowed. The distance L between the cutting blade leading portion 3 of the cutting blades 1 and 21 and the back surface of the main body portion 5 is about 5 to 10 mm. The width t of the main body 5 is about 2 to 3 mm. The height A of the main body 5 is about 2 to 4 mm and is larger than the width t. The depth of the groove in the constant depth portion 11 is, for example, about 60 to 80% of the height A of the main body portion 5. The width of the groove 10 is about 30 to 50% of the width t of the main body 5. The reason why the width and depth of the groove are made smaller than the width t and height A of the main body 5 is to maintain the rigidity of the main body 5.

図２（ａ）に示すように、裁断刃１の本体部５には、その高さＡのたとえば７０％程度の深さとなり、幅が本体部５の幅ｔの４０％程度となるよう溝１０の深さ一定部１１が形成される。 As shown in FIG. 2A, the main body 5 of the cutting blade 1 has a groove that has a depth of, for example, about 70% of the height A and a width of about 40% of the width t of the main body 5. Ten constant depth portions 11 are formed.

図２（ｂ）に斜線を施して示すように、裁断刃１は、切刃面４を研磨し、切れ味を維持しながら使用される。溝の深さ一定部１１は、研磨によって破線で示すように切刃面４が後退しても、裁断刃１の剛性が低下しない範囲に形成される。すなわち、図２（ｃ）に示すように、裁断刃１の本体部５は、ナイフガイド２０による支持および案内を受けながら上下動するけれども、ナイフガイド２０によって挟まれる部分には充分な剛性が必要となる。 As shown by hatching in FIG. 2B, the cutting blade 1 is used while polishing the cutting edge surface 4 and maintaining the sharpness. The groove depth constant portion 11 is formed in a range in which the rigidity of the cutting blade 1 does not decrease even when the cutting blade surface 4 is retracted as shown by a broken line by polishing. That is, as shown in FIG. 2C, the main body 5 of the cutting blade 1 moves up and down while being supported and guided by the knife guide 20, but a portion sandwiched by the knife guide 20 needs to have sufficient rigidity. It becomes.

図２（ｄ）は、本発明の実施の他の形態としての裁断刃２１の断面形状を示す。裁断刃２１は、裁断刃１よりも被裁断材の厚みが薄い場合に使用され、本体部５の幅ｔは、裁断刃１の幅ｔよりも若干小さくなる。切刃面４と本体部５との間には、凹部６が設けられる。溝の深さ一定部１１の深さは、本体部５の高さＡに対して、裁断刃２１は裁断刃１と同等であるけれども、深さ一定部１１の幅は、たとえば０．３５ｔ程度と、本体部５の幅ｔを基準として、裁断刃１の深さ一定部１１の幅よりも、さらに小さくしておく。 FIG.2 (d) shows the cross-sectional shape of the cutting blade 21 as another form of implementation of this invention. The cutting blade 21 is used when the material to be cut is thinner than the cutting blade 1, and the width t of the main body 5 is slightly smaller than the width t of the cutting blade 1. A recess 6 is provided between the cutting edge surface 4 and the main body 5. The depth of the constant groove depth portion 11 is equal to the height A of the main body 5 while the cutting blade 21 is equivalent to the cutting blade 1, but the width of the constant depth portion 11 is, for example, about 0.35 t. Then, the width t of the main body 5 is used as a reference, and the width is made smaller than the width of the constant depth portion 11 of the cutting blade 1.

図３は、裁断刃１，２１を自動裁断機の裁断ヘッド３０に装着している状態を簡略化して示す。裁断刃１，２１は、図示を省略している裁断ヘッド３０の上部側に設けられる駆動機構で上下動し、図は最下位置付近まで下降している状態を示す。裁断ヘッド３０の下端には、プレッサフット３１が設けられ、被裁断材となる生地３２の表面を押える。被裁断材は、布帛などのシート材の生地３２を複数枚積層させ、表面を非通気性シートで覆った状態で裁断テーブル上に載置され、裁断テーブルの下方から吸引して固定する。裁断テーブルの表面は、ブラシ３３で形成され、ブラシ３３中に裁断刃１，２１が侵入すると、ブラシ３３の剛毛は部分的に退避する。裁断刃１，２１は、積層状態の生地３２を、裁断刃１，２１を高速で上下動させながら裁断する。裁断ヘッド３０は、裁断テーブルの表面に沿う二次元的な移動と、裁断テーブル表面に対して接近または離反する移動とが可能である。裁断ヘッド３０内には、裁断刃１，２１を、図の上下方向の軸のまわりに回転させて、裁断の向きを変える機構も搭載されている。自動裁断機では、予め設定される裁断データに従って、裁断ヘッド３０の移動と裁断刃１，２１の向きを制御しながら、生地３２の裁断を行う。 FIG. 3 shows a simplified state where the cutting blades 1 and 21 are mounted on the cutting head 30 of the automatic cutting machine. The cutting blades 1 and 21 are moved up and down by a drive mechanism provided on the upper side of the cutting head 30 (not shown), and the drawing shows a state where the cutting blades 1 and 21 are lowered to the vicinity of the lowest position. A presser foot 31 is provided at the lower end of the cutting head 30 and presses the surface of the fabric 32 that is to be cut. The material to be cut is placed on a cutting table in a state where a plurality of sheet materials 32 such as cloth are stacked and the surface is covered with a non-breathable sheet, and is fixed by sucking from below the cutting table. The surface of the cutting table is formed by a brush 33, and when the cutting blades 1 and 21 enter the brush 33, the bristles of the brush 33 partially retract. The cutting blades 1 and 21 cut the laminated fabric 32 while moving the cutting blades 1 and 21 up and down at high speed. The cutting head 30 can move two-dimensionally along the surface of the cutting table and move toward or away from the cutting table surface. The cutting head 30 is also equipped with a mechanism for changing the cutting direction by rotating the cutting blades 1 and 21 around the vertical axis in the figure. In the automatic cutting machine, the fabric 32 is cut while controlling the movement of the cutting head 30 and the direction of the cutting blades 1 and 21 according to preset cutting data.

プレッサフット３１の上方の裁断ヘッド３０の内部には、裁断刃１，２１を支持しながら上下動するように案内するナイフガイド２０とともに、刃先の研磨を行う研磨ローラ３４も設けられる。研磨ローラ３４による研磨は、一定距離の裁断毎や一定時間毎など、予め設定される条件で、裁断刃１，２１を被裁断材から引抜いている状態で、裁断刃１，２１を上下動させ、研磨ローラ３４の作用を裁断範囲が均一に受けるようにしながら行われる。 Inside the cutting head 30 above the presser foot 31, there is also provided a polishing roller 34 for polishing the cutting edge together with a knife guide 20 for guiding the cutting blades 1 and 21 to move up and down while supporting them. Polishing by the polishing roller 34 is performed by moving the cutting blades 1 and 21 up and down in a state where the cutting blades 1 and 21 are pulled out from the material to be cut under predetermined conditions such as cutting at a certain distance and every predetermined time. The operation is performed while the cutting range is uniformly received by the action of the polishing roller 34.

図４は、裁断刃１での溝１０の有無による生地の溶着性の比較の一例を示す。シート材の生地３２として、合成皮革を２０枚積層し、自動裁断機として、株式会社島精機製作所の製品名Ｐ−ＣＡＭ１８２を使用すると、被裁断材として吸引時厚さは１５ｍｍとなるものを使用している。裁断刃１は、図の櫛形の図形を裁断するために、一旦被裁断材に突刺した状態を維持して、一筆書きのように、左下の起点から時計回り方向に一周させた。櫛形の図形全体の幅Ｗは２００ｍｍであり、全体の高さＨは１０５ｍｍであり、櫛の歯部分の幅ｗは１３ｍｍであり、櫛の歯部分の高さｈは９７ｍｍである。裁断ヘッドの移動速度である裁断速度１６ｍ／ｍｉｎで、裁断刃を毎分約２０００回上下動させる裁断条件で、裁断刃１を使用すれば、（ａ）に示すように、全パターンを良好に裁断することができた。溝１０を設けない裁断刃では、（ｂ）に示すように、裁断の途中で溶着を生じていることが確認された。溝１０が設けられていなくても、見かけ上、裁断パターンを一周させることはできる。しかしながら、「×」印の裁断箇所では、積層されたシート材が上下で溶着して分離が困難ないし不可能となり、「△」印の裁断箇所では、分離は可能な程度の溶着が生じている。溝１０の有無による溶着無し裁断可能距離は、溝１０有りの（ａ）で１９６３ｍｍとなるのに対し、溝無しの（ｂ）では６５５ｍｍとなり、溝１０を設ける効果が確認された。 FIG. 4 shows an example of the comparison of the weldability of the dough depending on the presence or absence of the groove 10 in the cutting blade 1. 20 sheets of synthetic leather are laminated as the sheet material 32, and when the product name P-CAM182 of Shima Seiki Seisakusho Co., Ltd. is used as an automatic cutting machine, a material with a suction thickness of 15 mm is used. is doing. In order to cut the comb-shaped figure in the figure, the cutting blade 1 was once pierced into the material to be cut and made a round in the clockwise direction from the lower left starting point as in a single stroke. The overall width W of the comb-shaped figure is 200 mm, the overall height H is 105 mm, the width w of the comb teeth is 13 mm, and the height h of the comb teeth is 97 mm. If the cutting blade 1 is used under the cutting conditions in which the cutting blade is moved up and down approximately 2000 times per minute at a cutting speed of 16 m / min, which is the moving speed of the cutting head, as shown in FIG. I was able to cut. It was confirmed that the cutting blade not provided with the groove 10 was welded during the cutting as shown in (b). Even if the groove 10 is not provided, the cutting pattern can be made to make one turn. However, it is difficult or impossible to separate the laminated sheet material at the cutting position marked “×”, and separation is difficult or impossible at the cutting position marked “△”. . The possible cutting distance without welding depending on the presence or absence of the groove 10 is 1963 mm when (a) with the groove 10 is 655 mm when (b) without the groove, and the effect of providing the groove 10 is confirmed.

図５は、裁断刃１での溝１０の有無による生地の溶着性の比較の他の例を示す。図４よりも裁断速度を低下させて１２ｍ／ｍｉｎとし、裁断刃を毎分約３０００回上下動させる裁断条件で裁断刃１を使用すれば、（ａ）に「○」印で示す範囲を溶着無しで裁断することが可能であると確認された。この溶着無し裁断可能距離は４３５ｍｍである。（ｂ）に示すように、溝無しでは、溶着無し裁断可能距離は２１０ｍｍに短縮される。このような溶着無し裁断可能距離の長短は、裁断の生産性に影響する。溶着無し裁断可能距離が短いと、生地３２の積層厚さ（枚数）を減らしたり、冷却のために裁断刃を生地３２から引上げるナイフアップを行う必要があり、裁断に要する時間が長くなってしまう。 FIG. 5 shows another example of the comparison of the fabric weldability depending on the presence or absence of the groove 10 in the cutting blade 1. If the cutting blade 1 is used under a cutting condition in which the cutting speed is 12 m / min lower than that in FIG. 4 and the cutting blade is moved up and down approximately 3000 times per minute, the range indicated by “◯” in (a) is welded. It was confirmed that it was possible to cut without any. The possible cutting distance without welding is 435 mm. As shown in (b), without a groove, the possible cutting distance without welding is shortened to 210 mm. The length of the possible cutting distance without welding affects the productivity of cutting. If the possible cutting distance without welding is short, it is necessary to reduce the stacking thickness (number of sheets) of the fabric 32 or to raise the cutting blade from the fabric 32 for cooling, which increases the time required for cutting. End up.

図４および図５に示すように、裁断刃１では、背面側に溝１０を設けているので、溝１０内を流通する空気によって裁断刃１が冷却され、被裁断材が溶着を生じるまでの温度上昇が抑制される。図２（ｄ）に示す裁断刃２１でも同様であると期待される。自動裁断機では、被裁断材を載置する裁断テーブルの下方から吸引して被裁断材を裁断テーブル上に固定する状態で裁断が行われるので、溝１０を吸気が通過し、冷却が効率よく行われる。溝１０が開口するのは、裁断刃１，２１の背面側であるので、特許文献１の図７に示されているように、被裁断材との接触はなく、吸気の通路は確保される。裁断刃１、２１の背面側に溝１０を設けることによって、裁断刃１０，２１の放熱面積が増加し、放熱面と発熱部との距離も短縮され、効率的な冷却が可能になる。 As shown in FIG. 4 and FIG. 5, the cutting blade 1 is provided with the groove 10 on the back side, so that the cutting blade 1 is cooled by the air flowing through the groove 10 until the material to be cut is welded. Temperature rise is suppressed. The same is expected for the cutting blade 21 shown in FIG. In the automatic cutting machine, since cutting is performed in a state in which the material to be cut is sucked from below the cutting table on which the material to be cut is placed and the material to be cut is fixed on the cutting table, the intake air passes through the groove 10 and cooling is efficiently performed. Done. Since the groove 10 opens on the back side of the cutting blades 1 and 21, as shown in FIG. 7 of Patent Document 1, there is no contact with the material to be cut and an intake passage is secured. . By providing the groove 10 on the back side of the cutting blades 1 and 21, the heat dissipating area of the cutting blades 10 and 21 is increased, the distance between the heat dissipating surface and the heat generating portion is shortened, and efficient cooling becomes possible.

なお、以上では、裁断刃１，２１の本体部５に設ける溝１０が角溝である場合を示しているけれども、溝１０の断面は、Ｖ溝のように底部で幅が減少したり、Ｕ溝のように底面が曲面であってもよい。これらの断面形状は、切削工具の刃先形状に応じて変化させることができる。 In addition, although the case where the groove | channel 10 provided in the main-body part 5 of the cutting blades 1 and 21 is a square groove | channel is shown above, the cross section of the groove | channel 10 reduces a width | variety at a bottom part like a V groove, or U The bottom surface may be a curved surface like a groove. These cross-sectional shapes can be changed according to the cutting edge shape of the cutting tool.
