[Technical field to which the invention belongs]

本考案は、段ボール紙を打抜き加工する段ボール打抜き型に取り付ける罫線の改良に関する。 The present invention relates to an improvement of a ruled line attached to a cardboard punching die for punching corrugated paper.

【０００２】[0002]

[Prior art]

従来から知られているこの種の段ボール打抜き型用の罫線Ａ’は図６に例示したように直線である。 A conventionally known ruled line A 'for a cardboard punching die of this type is a straight line as illustrated in FIG.

【０００３】[0003]

[Problems to be solved by the invention]

従って、段ボール打抜き時に段ボール紙Ｃのライナー２に押し込まれると、ライナー２には直線的に同一方向の力がその押し込み方向に集中して掛かる。そのために、従来では図７に例示したように罫線Ａ’が段ボール紙Ｂのライナー２を突き抜けてしまうと言った割れ（破れ）が発生してしまうものであった。又、従来では段ボール打抜き時にライナー２への押し込み量を小さくしたり、罫線（溝）を入れるその周りのライナー２を押し潰して割れの発生を防ぐなどの工夫を施しいたが、この様に罫線を入れるその周りを潰してしまうと、罫線を入れた部分の折曲げ強度が顧客の要求する数値まで行かなかったりなどの新たな問題が起きていた。因みに、罫線の先端部の縦断面形状は球面形（Ｒ形）、角形、Ｖ字形、或いは厚さ方向中央に溝を入れた溝形などの種々の形状に加工されている。 Therefore, when the liner 2 is pushed into the liner 2 of the corrugated cardboard C at the time of punching out the corrugated cardboard, a force in the same direction is linearly concentrated on the liner 2 in the pushing direction. For this reason, conventionally, as shown in FIG. 7, cracks (breaks) occur in which the ruled line A 'penetrates through the liner 2 of the cardboard paper B. In the past, measures were taken to reduce the amount of press into the liner 2 when punching corrugated cardboard, and to crush the liner 2 around the crease (groove) to prevent the occurrence of cracks. If the area around the line is crushed, new problems such as the bending strength of the part with the ruled line failing to reach the value required by the customer have arisen. Incidentally, the vertical cross-sectional shape of the tip of the ruled line is processed into various shapes such as a spherical shape (R shape), a square shape, a V-shape, or a groove shape having a groove in the center in the thickness direction.

【０００４】本考案はこの様な従来事情に鑑みてなされたもので、その目的とする処は、割れ等を発生させることなく、しかも、折曲げ強度を損なうことなく段ボール紙に罫線（溝）を入れることができるように改良した段ボール打抜き型用罫線を提供することにある。[0004] The present invention has been made in view of such a conventional situation, and its purpose is to create a ruled line (groove) on corrugated paper without causing cracks or the like and without impairing bending strength. The present invention provides an improved corrugated cardboard punching crease so that a crease can be inserted.

【課題を達成するための手段】上記目的を達成するために本考案は、段ボール打抜き型に取り付ける罫線に於いて、段ボール紙に押し込まれる先端部を含めた先端側を少なくとも横断面波形に形成してなることを要旨とする。又、上記波形先端部の内側頂点が罫線の長手方向に同一線上に位置していることを要旨とする。そして、波形先端部の外側頂点から内側頂点（波形に連設する山から谷）に至るピッチが２mm〜10mmであり、一側面側の外側頂点から他側面側の外側頂点までの幅が２mm〜10mmであり、更に罫線の加工幅、つまり罫線の厚さが 1.0mm〜 3.0mmであり、これらの寸法は段ボール紙の材質や段種などにより決定されるものである。Means for Achieving the Object In order to achieve the above object, the present invention provides a ruled line attached to a corrugated cardboard punching die, in which at least the leading end including the leading end pushed into the corrugated cardboard is formed into a cross-sectional waveform. The gist is that The gist is that the inside apex of the waveform tip is located on the same line in the longitudinal direction of the ruled line. The pitch from the outer vertex of the waveform tip to the inner vertex (peak to valley connected to the waveform) is 2 mm to 10 mm, and the width from the outer vertex on one side to the outer vertex on the other side is 2 mm to The width of the ruled line, that is, the thickness of the ruled line is 1.0 mm to 3.0 mm, and these dimensions are determined by the material and type of corrugated paper.

[Embodiment of the invention]

本考案の実施の形態を図面に基づいて以下説明する。図１は段ボール打抜き型Ｂに取り付けられる本考案波形罫線Ａの実施の一例を示し、所要の長さと幅（高さ）を有する帯板状（プレート状）を成し、その先端部を含めた先端側を横断面波形に形成する。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of the implementation of the corrugated crease A of the present invention attached to a corrugated cardboard punching die B. The corrugated crease A has a strip shape (plate shape) having a required length and width (height). The tip side is formed into a cross-sectional waveform.

【０００７】波形先端部１は、波形罫線Ａの先端から少なくとも４mmの範囲Ｌ₁で、しかも、図１（ロ）の拡大図に図示したように、各内側頂点1-1 …が罫線Ａの長手方向に同一線上Ｘに位置するように折曲げ形成してなる。そして、外側頂点1-2 から内側頂点1-1 （波形に連設する山から谷）に至るピッチを２mm〜10mmの範囲Ｌ₂で、一側面側の外側頂点1-2 から他側面側の外側頂点1-2 までの幅を２mm〜10mmの範囲Ｌ₃で、更に罫線（溝）の加工幅、つまり波形罫線Ａの厚さを 1.0mm〜 3.0mmの範囲Ｌ₄で設定する事が好ましく、これらの寸法は段ボール紙Ｃの材質や段種などにより決定されるものである。又、波形先端部１の縦断面形状は例えば球面形（Ｒ形）（図１（ハ）参照）、角形（図１（ニ）参照）等の任意の形状に加工してなる。The waveform tip 1 has a range L ₁ of at least 4 mm from the tip of the waveform ruled line A. Further, as shown in the enlarged view of FIG. It is formed by bending so as to be located on the same line X in the longitudinal direction. The pitch from the outer vertex 1-2 to the inner vertex 1-1 (peak to valley connected to the waveform) is L2 in the range of ₂ mm to 10 mm. setting the width to the side of the outer vertex 1-2 range L ₃ of 2 mm to 10 mm, further processing width of the ruled line (groove), that is, the thickness of the wave-shaped border a range L ₄ of 1.0 mm to 3.0 mm These dimensions are preferably determined by the material and the type of the corrugated paper C. Further, the longitudinal cross-sectional shape of the corrugated tip portion 1 is processed into an arbitrary shape such as, for example, a spherical shape (R shape) (see FIG. 1 (c)) and a square shape (see FIG. 1 (d)).

【０００８】而して、以上の如く構成した本実施例の波形罫線Ａによれば、段ボール打抜き時に段ボール紙Ｃのライナー２にその波形先端部１が押し込まれると（図２の状態から図３の状態）、ライナー２には図４に示した各方向、詳しくは波形先端部１の波線に対して夫々略直交する各分散された方向の力がその押し込み方向に掛かり、ライナー２には罫線（溝）３が加工される（図３及び図５の状態）。従って、波形先端部１による押し込み方向の力が分散されることによって、ライナー２が割れることはない。又、波形先端部１を波形罫線Ａの先端から少なくとも４mmの範囲Ｌ₁で形成して該波形罫線Ａの櫛形加工を可能にしてなることから、リング状形態での使用が可能となる（図１（イ）の二点鎖線の状態）。それにより、平形、ロータリー等の段ボール打抜き機械全てに対応させる事ができる。According to the corrugated ruled line A of the present embodiment configured as described above, when the corrugated tip 1 is pushed into the liner 2 of corrugated paper C at the time of punching corrugated cardboard (from the state of FIG. 2 to FIG. 2). 3), a force is applied to the liner 2 in each of the directions shown in FIG. 4, more specifically, in each of the dispersed directions substantially orthogonal to the wavy line of the wave-shaped front end portion 1 in the pushing direction. In the figure, the ruled line (groove) 3 is processed (the state of FIGS. 3 and 5). Accordingly, the liner 2 does not break due to the dispersion of the force in the pushing direction by the corrugated tip 1. Further, since the corrugated tip ₁ is formed in a range L1 of at least 4 mm from the tip of the corrugated ruled line A to enable the comb-shaped processing of the corrugated ruled line A, it can be used in a ring form. (The state of the two-dot chain line in FIG. 1A). As a result, it is possible to correspond to all cardboard punching machines such as flat type and rotary type.

【０００９】尚、波形罫線Ａの先端部の横断面形状は波形に限らず、段ボール打抜き時に段ボール紙Ｃのライナー２に押し込まれた際、該ライナー２に直線的に同一方向の力がその押し込み方向に集中して掛からないように、力を分散する形状であれば良く、例えば角のないジグザグ形状等任意である。The cross-sectional shape of the leading end of the corrugated ruled line A is not limited to a corrugated shape. Any shape may be used as long as it disperses the force so that the force is not concentrated in the pushing direction.

【００１０】[0010]

[Effect of the invention]

本考案の段ボール打抜き型用波形罫線は叙上の如く構成してなるから、下記の作用効果を奏する。段ボール紙に押し込まれる波形罫線の先端部を含めた先端側を少なくとも横断面波形に形成して、段ボール打抜き時に段ボール紙のライナーに押し込まれた際、波形先端部の波線に対して夫々略直交する各分散された方向の力がその押し込み方向に掛かるように形成してなることから、従来のように直線的に同一方向の力がその押し込み方向に集中して掛かることにより発生していたライナーの割れを防ぐ事ができる。 The corrugated cardboard punching type corrugated ruled line of the present invention is configured as described above, and has the following operational effects. At least the cross-section waveform is formed at the tip end including the tip of the corrugated ruled line pushed into the corrugated paper, and when it is pushed into the liner of corrugated paper at the time of punching out corrugated cardboard, it is almost perpendicular to the wavy line of the corrugated tip. Since the forces in each of the dispersed directions are formed so as to be applied in the pushing direction, the force is generated by the force in the same direction being concentrated linearly in the pushing direction as in the past. The breakage of the liner can be prevented.

【００１１】従って、本考案の波形罫線によれば、割れの発生のない分散型押し込みにより段ボール紙のライナーに罫線を加工することができる。しかも、従来のように、割れを防ぐために、罫線の加工高さそのものを低くしたり、罫線の周りを潰すなどの余計なことが一切不要となることから、折曲げ強度を損なうこともなく、顧客の要望に応えた折曲げ強度にて段ボール紙のライナーに罫線を加工することができる。Therefore, according to the corrugated ruled line of the present invention, it is possible to process the ruled line on the liner of corrugated cardboard by the decentralized indentation without crack generation. Moreover, unlike the conventional method, there is no need to reduce the processing height of the ruled line itself or crush the area around the ruled line in order to prevent cracking. Ruled lines can be formed on corrugated cardboard liners with a bending strength that meets customer demands.
