従来から、ベニヤ合板や金属板などの基板に、切れ目線用やミシン目線用の打 抜刃と折り目線用の罫線部材とを設けて、この打抜刃の刃先の両側面に、スポン ジ体を近接して位置させた紙箱などの打抜型が広く用いられているものである。 すなわち、図２に示すように、押圧鉄板(50)が下降して、板紙など(40)に切れ目 線やミシン目線や折り目線を設ける打抜き動作時に、打抜刃(20,20)の刃先が板 紙など(40)に鋭く食込むものであって、続いて押圧鉄板(50)が上昇して、切れ目 線やミシン目線や折り目線を設けた板紙など(40)を排出する紙送り動作時に、板 紙など(40)に鋭く食込んだ打抜刃(20,20)の刃先を抜取る必要があって、押圧反 発性が優れたスポンジゴムシートなどの、厚さ１０〜１５mmのスポンジ体(30,30 ,30,30)を基板(10)に接着して、この打抜刃(20,20)の刃先の両側面の１０〜３０ mm幅の部分に、スポンジ体(30,30,30,30)を近接して位置させているものである 。なお、罫線部材(21,21)については、打抜き動作時に板紙など(40)に食込まな いものであって、スポンジ体(30)を位置させる必要がないものである。 Conventionally, a board such as plywood or metal plate is provided with punching blades for cutting lines and perforation lines and crease line rule members, and sponge bodies are attached to both sides of the cutting edge of the punching blades. A punching die such as a paper box in which the two are positioned close to each other is widely used. That is, as shown in FIG. 2, when the pressing iron plate (50) descends to make a cut line, a perforation line or a crease line on the board (40), etc., the cutting edge of the punching blade (20, 20) is It is something that sharply digs into the board (40), etc., and then the pressing iron plate (50) rises and ejects the board (40) with cut lines, perforation lines or fold lines. A sponge with a thickness of 10 to 15 mm, such as a sponge rubber sheet that has excellent pressure resilience, because it is necessary to remove the cutting edge of the punching blade (20, 20) that has sharply cut into the board (40). The body (30,30,30,30) is adhered to the substrate (10), and the sponge body (30,30,30) is attached to both sides of the cutting edge of the punching blade (20,20) with a width of 10 to 30 mm. , 30,30) are located close to each other. Note that the ruled line members (21, 21) do not bite into the board (40) or the like during the punching operation, and it is not necessary to position the sponge body (30).
【０００３】[0003]
図３は、前述した従来の紙箱などの打抜型において、板紙やプラスチックシー トなどが基板へ密着した状態を示す部分断面図である。すなわち、前述したよう に、板紙など(40)に鋭く食込んだ打抜刃(20,20)の刃先を抜取る必要があって、 この打抜刃(20,20)の刃先の両側面に、スポンジ体(30,30,30,30)を近接して位置 させたことによって、押圧鉄板(50)が上昇した紙送り動作時に、押圧反発性が優 れたスポンジ体(30,30,30,30)が急激に膨張して板紙など(40)を押上げるために 、その反動で、基板(10)のスポンジ体(30,30)で囲まれた部分と板紙など(40)と の間の空間が減圧されて、一時的に、板紙など(40)が基板(10)へ密着した状態を 示したものである。 FIG. 3 is a partial cross-sectional view showing a state in which a paperboard, a plastic sheet, or the like is in close contact with the substrate in the above-mentioned conventional punching die such as a paper box. That is, as described above, it is necessary to remove the cutting edge of the punching blade (20, 20) that has sharply cut into the board (40), etc. , The sponge body (30,30,30,30) is located close to the sponge body (30,30,30), which is excellent in the press repulsion property during the paper feeding operation in which the pressing iron plate (50) is raised. , 30) rapidly expands and pushes up the board (40), etc., so that the reaction between the part surrounded by the sponge body (30, 30) of the board (10) and the board (40). The space is decompressed, and the board (40) or the like (40) is temporarily brought into close contact with the substrate (10).
【０００４】 最近の、打抜工程の自動化,高速化にともなって、たとえ一時的であっても、 板紙など(40)が基板(10)へ密着した状態を示すことが問題であって、前述した切 れ目線やミシン目線や折り目線を設けた板紙など(40)を排出することが困難にな って、また排出した板紙など(40)が揃わないものであって、この打抜刃(20,20) の刃先の両側面に加えて、基板(10)のスポンジ体(30,30)で囲まれた部分(すなわ ち、打抜刃(20,20)で囲まれた部分)と板紙など(40)との間の空間全体に、押圧反 発性が優れたスポンジ体(30)を位置させる必要があるものであった。With the recent automation and speeding up of the punching process, it has been a problem that the board (40) or the like shows a state in which the board (40) adheres to the substrate (10) even temporarily. It is difficult to eject the paperboard (40) with cut lines, perforation lines or fold lines, and the ejected paperboard (40) is not aligned. In addition to both sides of the cutting edge of (20, 20), the part surrounded by the sponge body (30, 30) of the substrate (10) (that is, the part surrounded by the punching blades (20, 20)) It was necessary to position the sponge body (30) having excellent pressing resilience in the entire space between the board (40) and the like.
【０００５】 なお、前述した板紙など(40)が基板(10)へ密着した状態を示す問題を解決する ために、例えば、実開昭56-8426号公報(木型における抜型刃の保持溝)において は、基板(10)と打抜刃(20)との間に、波状の空気抜き隙間を設けた考案が開示さ れているものであって、また例えば、実開昭58-4400号公報(厚紙等の平面打抜き 機に於ける打抜き型用刃)においては、打抜刃(20)の刃先の直下部に、空気抜き 窓孔を設けた考案が開示されているものである。しかしながら、この打抜刃(20, 20)の刃先の両側面に、スポンジ体(30,30,30,30)を近接して位置させたことによ って、いずれも空気抜き効果が不充分であって、板紙など(40)が基板(10)へ密着 した状態を示す問題を解決できなかった。In order to solve the above-mentioned problem that the paper board (40) is in close contact with the substrate (10), for example, Japanese Utility Model Laid-Open No. 56-8426 (holding groove for a die-cutting blade in a wooden mold) Discloses a device in which a corrugated air bleeding gap is provided between the substrate (10) and the punching blade (20), and, for example, in Japanese Utility Model Laid-Open No. 58-4400. For a die for a punching die in a plane punching machine such as a cardboard, there is disclosed a device in which an air vent window is provided directly below the cutting edge of the punching blade (20). However, since the sponge bodies (30, 30, 30, 30) were positioned close to both sides of the cutting edge of the punching blades (20, 20), the air bleeding effect was insufficient in all cases. Therefore, the problem that the board (40) and the like (40) adhere to the substrate (10) could not be solved.
