Abstract
Description
本発明は、シート材を所定の形状に切断するカッティング装置に関する。 The present invention relates to a cutting device that cuts a sheet material into a predetermined shape.
従来より、合成樹脂製フィルム、薄紙または厚紙等のシート材から、展開した箱等の所定形状打抜片を打ち抜くために、打抜機が用いられている。従来の打抜機は、抜型と、これに相対向する面板とからなり、シート材が載置された面板に抜型を圧接することにより当該シート材を打ち抜くものである（特許文献１等参照）。 2. Description of the Related Art Conventionally, a punching machine has been used to punch a punched piece of a predetermined shape such as a developed box from a sheet material such as a synthetic resin film, thin paper, or cardboard. A conventional punching machine includes a punching die and a face plate opposed to the die, and punches the sheet material by press-contacting the punching die to the face plate on which the sheet material is placed (see Patent Document 1, etc.).
このような打抜機では、カウンタプレート上に、合成樹脂フィルム、薄紙、厚紙等のシート材を載置し、受け面に切断刃を圧接することにより、シート材を所望の形状に打ち抜くことができるが、切断刃が受け面に圧接されるので、打ち抜きを繰り返すことによって、切断不良が発生するという問題がある。特に、フィルム、薄紙などの打ち抜きでは切断不良が生じ易い。 In such a punching machine, a sheet material such as a synthetic resin film, thin paper, or thick paper is placed on the counter plate, and a cutting blade is pressed against the receiving surface, whereby the sheet material can be punched into a desired shape. However, since the cutting blade is pressed against the receiving surface, there is a problem in that cutting failure occurs due to repeated punching. In particular, when a film, thin paper, or the like is punched, cutting failure is likely to occur.
また、切断刃が受け面に均一に圧接されなければならないので、打ち抜き開始前には、むら取り作業を行う必要があり、多大な作業時間を要するという問題がある。 Further, since the cutting blade must be uniformly pressed against the receiving surface, it is necessary to perform unevenness work before punching is started, and there is a problem that it takes a lot of work time.
本発明は上記状況に鑑み、従来の打抜機とは異なり、特にフィルムや薄紙の切断に好適なカッティング装置を提供することを目的とする。 In view of the above situation, an object of the present invention is to provide a cutting device particularly suitable for cutting a film or thin paper, unlike a conventional punching machine.
前記目的を達成する本発明の第１の態様は、シート材を切断する切断刃を固定した切断型と、前記シート材を載置する受け型とを具備するカッティング装置であって、前記切断刃は、切断方向に突出する山部と、当該山部に挟まれた谷部とからなる刃部を具備し、前記受け型は、前記切断刃に対応する領域に当該切断刃の刃部が挿入される凹部を有することを特徴とするカッティング装置にある。 A first aspect of the present invention that achieves the above object is a cutting apparatus comprising: a cutting die that fixes a cutting blade that cuts a sheet material; and a receiving die that mounts the sheet material, the cutting blade Comprises a blade part composed of a peak part projecting in the cutting direction and a valley part sandwiched between the peak parts, and the receiving mold has the blade part of the cutting blade inserted in a region corresponding to the cutting blade. A cutting apparatus having a recessed portion.
本発明の第２の態様は、第１の態様において、前記切断刃の刃部の側面視形状が、鋸歯形状、三角波形状又は波形形状であることを特徴とするカッティング装置にある。 According to a second aspect of the present invention, in the first aspect, the cutting device is characterized in that a side view shape of the blade portion of the cutting blade is a sawtooth shape, a triangular wave shape, or a corrugated shape.
本発明の第３の態様は、第１又は２の態様において、前記切断刃の厚さ方向両側には、押さえ部材が設けられていることを特徴とするカッティング装置にある。 A third aspect of the present invention is the cutting apparatus according to the first or second aspect, wherein pressing members are provided on both sides in the thickness direction of the cutting blade.
本発明の第４の態様は、第１〜３の何れか一つの態様において、前記凹部が溝又は貫通穴であることを特徴とするカッティング装置にある。 A fourth aspect of the present invention is the cutting apparatus according to any one of the first to third aspects, wherein the concave portion is a groove or a through hole.
本発明によれば、切断刃の山部の先端でシート材に穴が形成され、山部及びこれに連続する谷部に形成された刃先によりシート材がカッティングされ、所定の形状に切断されるが、切断刃の刃部は受け型に形成された凹部に入り込み、受け面に当接することがないので、刃潰れなどによる切断不良が生じないという効果を奏する。 According to the present invention, a hole is formed in the sheet material at the tip of the crest portion of the cutting blade, and the sheet material is cut by the cutting edge formed in the crest portion and a trough portion continuous therewith, and cut into a predetermined shape. However, since the blade portion of the cutting blade enters the recess formed in the receiving mold and does not contact the receiving surface, there is an effect that cutting failure due to crushing of the blade does not occur.
以下に、本発明を実施形態に基づいて詳細に説明する。 Hereinafter, the present invention will be described in detail based on embodiments.

In FIG. 1, the schematic cross section of the cutting apparatus of this invention is shown.
図１に示すように、カッティング装置１００は、上部定盤１０１及び下部定盤１０２を有し、固定された上部定盤１０１に対して下部定盤１０２が駆動装置（図示せず）によって接近離反方向に駆動されるようになっている。上部定盤１０１の下面には、チェース１０３が取り付けられると共に、下部定盤１０２の上面にはデッドプレート１０４が取り付けられる。ここで、チェース１０３は、カッティング装置１００の上部定盤１０１に精度良く位置決め固定される汎用治具の一つであり、デッドプレート１０４は、下部定盤１０２に精度良く位置決め固定される汎用治具の一つである。 As shown in FIG. 1, the cutting device 100 has an upper surface plate 101 and a lower surface plate 102, and the lower surface plate 102 is moved closer to and away from the fixed upper surface plate 101 by a driving device (not shown). It is driven in the direction. A chase 103 is attached to the lower surface of the upper surface plate 101, and a dead plate 104 is attached to the upper surface of the lower surface plate 102. Here, the chase 103 is one of general-purpose jigs that are accurately positioned and fixed to the upper surface plate 101 of the cutting apparatus 100, and the dead plate 104 is a general-purpose jig that is accurately positioned and fixed to the lower surface plate 102. one of.
上部定盤１０１に固定されている切断型１０は、ダイボード１１に切断刃１２が固定されたものである。ダイボード１１は、通常ベニヤ板、樹脂板あるいは金属板からなり、ダイボード１１には、一般にはレーザ加工により固定溝１４が形成されている。一方、切断刃１２は帯状の板材を所定の長さに切断後、屈曲したものであり、ダイボード１１に形成された固定溝１４に挿入固定されている。また、切断刃１２の厚さ方向両側には、ゴム、発泡ゴム、エラストマーなどの弾性部材からなる押さえ部材１５が設けられている。なお、押さえ部材１５の先端は、切断刃１２の先端より図中下方に突出しており、当該押さえ部材１５が押圧方向に弾性変形することにより、切断刃１２の先端が押さえ部材１５より突出するようになっている。 The cutting die 10 fixed to the upper surface plate 101 is obtained by fixing a cutting blade 12 to a die board 11. The die board 11 is usually made of a veneer plate, a resin plate, or a metal plate, and a fixing groove 14 is generally formed in the die board 11 by laser processing. On the other hand, the cutting blade 12 is obtained by cutting a strip-shaped plate material into a predetermined length and then bending it, and is inserted and fixed in a fixing groove 14 formed in the die board 11. Further, on both sides of the cutting blade 12 in the thickness direction, pressing members 15 made of an elastic member such as rubber, foam rubber, or elastomer are provided. Note that the tip of the pressing member 15 protrudes downward in the drawing from the tip of the cutting blade 12, and the tip of the cutting blade 12 protrudes from the pressing member 15 when the pressing member 15 is elastically deformed in the pressing direction. It has become.
一方、デッドプレート１０４上に固定されて面板２０は、約１〜１．５ｍｍ厚の金属板材からなり、切断刃１２に対応する部分に、凹部となる凹溝２１が形成されており、他の部分は平面状の受け面２２となっている。 On the other hand, the face plate 20 fixed on the dead plate 104 is made of a metal plate material having a thickness of about 1 to 1.5 mm, and a groove 21 serving as a recess is formed in a portion corresponding to the cutting blade 12. The portion is a flat receiving surface 22.
ここで、切断刃１２は、厚さ方向の側面から見た側面視を表す図２に示すように、先端に、切断方向に突出する山部１３ａと、当該山部１３ａに挟まれた谷部１３ｂ（図２参照）とからなる刃部１３を具備する。すなわち、切断刃１２の先端は、側面視形状が、鋸歯形状、三角波形状又は波形形状である。切断刃１２は、鋼、ステンレス鋼、軟鋼、鉄など金属製の他、樹脂製であってもよい。 Here, as shown in FIG. 2 representing a side view as viewed from the side surface in the thickness direction, the cutting blade 12 has a peak portion 13a protruding in the cutting direction at the tip, and a valley portion sandwiched between the peak portions 13a. The blade part 13 which consists of 13b (refer FIG. 2) is comprised. That is, the tip of the cutting blade 12 has a sawtooth shape, a triangular wave shape, or a wave shape when viewed from the side. The cutting blade 12 may be made of resin in addition to metal such as steel, stainless steel, mild steel, and iron.
また、切断刃１２の保持方法は、上述したものに限定されず、貫通しない溝に保持する方法などでもよい。 Moreover, the holding method of the cutting blade 12 is not limited to what was mentioned above, The method etc. which hold | maintain in the groove | channel which does not penetrate may be sufficient.
また、図示する切断刃１２は、厚さ方向両側に刃を設けた両刃となっているが、片方のみに刃を設けた片刃であってもよい。 The illustrated cutting blade 12 is a double-edged blade provided on both sides in the thickness direction, but may be a single-edged blade provided on only one side.
図２（ａ）は、鋸歯形状又は三角波形状であり、山部１３ａ及び谷部１３ｂは左右対称となっている。 FIG. 2A shows a sawtooth shape or a triangular wave shape, and the crest portion 13a and the trough portion 13b are symmetrical.
図２（ｂ）は、鋸歯形状又は三角波形状であり、山部１３ａ及び谷部１３ｂは左右非対称となっている。 FIG. 2B shows a sawtooth shape or a triangular wave shape, and the crest 13a and the trough 13b are asymmetrical.
図２（ｃ）は、波形形状であり、山部１３ａ及び谷部１３ｂが左右対称となる例を示したが、非対称であってもよい。 Although FIG.2 (c) showed the waveform shape and showed the example from which the peak part 13a and the trough part 13b are left-right symmetric, it may be asymmetrical.
このようなカッティング装置１００により、カッティングを行う状態を図３を参照しながら説明する。 A state in which cutting is performed by such a cutting apparatus 100 will be described with reference to FIG.
まず、図３（ａ）に示すように、面板２０上に被切断物であるシート材３０を載置し、図３での図示は省略する、固定された上部定盤１０１に対して下部定盤１０２が駆動装置（図示せず）によって接近方向に駆動する。これにより、図３（ｂ）に示すように、まず、押さえ部材１５がシート材３０に当接して押さえつけ、弾性変形していく。次に、図３（ｃ）に示すように、切断刃１２の山部１３ａの先端がシート材３０に当接し、内部に進入し（図３（ｄ））、山部１３ａの刃と谷部１３ｂ（図２参照）の刃によりシート材３０が切断される（図３（ｅ））。このとき、切断刃１２の先端は凹溝２１内に存在する。 First, as shown in FIG. 3A, a sheet material 30 as an object to be cut is placed on the face plate 20, and the lower plate is fixed with respect to the fixed upper platen 101, which is not shown in FIG. The board 102 is driven in the approaching direction by a driving device (not shown). As a result, as shown in FIG. 3B, first, the pressing member 15 contacts and presses against the sheet material 30, and is elastically deformed. Next, as shown in FIG. 3C, the tip of the crest 13a of the cutting blade 12 abuts on the sheet material 30 and enters the inside (FIG. 3D), and the crest and trough of the crest 13a. The sheet material 30 is cut by the blade 13b (see FIG. 2) (FIG. 3E). At this time, the tip of the cutting blade 12 exists in the concave groove 21.
このように、上述したカッティング装置１００での切断は、従来の打抜や剪断加工とは全く異なる機構によるものであり、特に、薄い樹脂製などのフィルム、シート、薄い紙などの被切断物のカッティングに効果的であり、刃潰れなどによる切断不良の心配もない。 As described above, the cutting with the above-described cutting apparatus 100 is based on a mechanism that is completely different from conventional punching and shearing processes, and in particular, a cut object such as a thin resin film, sheet, thin paper, or the like. It is effective for cutting and there is no fear of cutting failure due to crushing of the blade.
また、装置セッティング時におけるムラ取りなどの作業も不要となるという利点もある。 In addition, there is an advantage that work such as unevenness removal at the time of device setting is not required.
