Description

【０００１】
【発明の属する技術分野】
本発明は、枚葉紙にホログラム等の光学的視認変化素子（オプティカル・バリアブル・デバイス（ＯＶＤ））を形成した箔を箔押しする箔押し機に関する。
【０００２】
【従来の技術】
近年、最もセキュリティ性が要求される銀行券、有価証券、パスポート等の貴重印刷物には、例えば、ユーロ券にも代表されるように、ホログラムが箔押しされている。また、各種クレジットカード、ＩＣカード、商品券や入場券等にもホログラムが箔押しされるようになり、ホログラム箔押し利用製品は多岐に渡る。これら多くの貴重製品にホログラムが利用される理由として、ホログラムには、視認角度を変えるとその画像や色が顕著に変化する特性があるため、誰にでも容易に真偽判別が可能で、且つ、偽造が難しいという利点があるためである。
【０００３】
また、ホログラムは、箔表層の回折格子を工夫し、光学的な変化をより一層ダイナミックにしたり、隠し情報を付与する等の技術も開発されている。一方では、図７に示すような、ホログラム等の光学的に視認変化する偽造防止情報図柄が形成された金属箔からなる図柄箔Ｃと、この図柄箔Ｃに対応して設けられ、その位置を指定するためのレジスタマーク（又はタイミングマーク）Ｂとを一対に形成し、これらを一定間隔隔てて形成した箔貼着フィルムロールＡを用いて箔押しする箔押し機があり、このような箔押し機は、図１１に示すように、レジスタマークＢを光学センサーで読み取り、読み取ったタイミングに合わせて、箔押し機のプレス部で図柄箔Ｃのみを紙やカード等の基材に箔押しすることにより、図柄箔Ｃを常に一定の位置に箔押しできるという利点がある。
【０００４】
前記箔押し機の主な機構は、図１１に示すように、給紙部２、箔押し部３、排紙部４、箔送り（搬送）部５からなる。具体的には、まず、給紙部２で基材となる用紙６等が積層されたものから用紙６を１枚つづ取り出し、箔押し部３に搬送する。一方、箔送り（搬送）部５では、箔貼着フィルムロールＡを箔投入部５ａに取り付け、この箔が搬送されて箔押し部３を通過した後、箔再巻取り部５ｂで巻き取られる。箔押し部３では、前記給紙部２から搬送された用紙６と前記箔投入部５ａ搬送された箔とが対峙し、これらの上側に設置された固定板３ａには凸状の刻印が形成され、且つ高温で加熱され、これらの下側に設置された加圧板３ｂが上下移動動作を繰り返し、これが上に移動した時に、用紙６と箔の、特に、ホログラム図柄Ｃ部分を加熱圧着することにより、用紙６に箔図柄が貼付され、箔図柄が貼付された用紙６は排紙部４に順次排出、積層される。一方、箔図柄が箔押しされた後の箔は、箔再巻取り部５ｂに巻き取られる。
【０００５】
一方、箔押し機によっては、前記のような箔の位置を指定するためのレジスタマーク（又はタイミングマーク）Ｂを設けずに、図柄箔を箔押しするタイプの箔押し機もある。
従来、箔押し機で箔が貼付された用紙の品質を確認するには、排紙部４に排出された用紙を抜取り、人手による目視検査して貼付品質を確認していた。このような人手による貼付品質検査を改善するために、箔貼付機に箔貼付検査機構を設ける方法又は装置（例えば、特開平２００２−３９７２９号公報参照。）が提案されている。しかし、この方法又は装置は、図１０に示すように、箔押しした後の残箔の図柄箔Ｃが抜けた部分に光を照射して抜け落ちた部分の面積を測定し、その面積が所定範囲以内であるか否かにより、箔押しが確実に行われたどうかを判断するため、図８に示すように、図柄箔Ｄの領域及びその他の領域り全面に箔が蒸着される蒸着フィルムＧ（以下、全面箔貼着フィルムという。）の場合には対応できるが、図９に示す、図柄箔Ｄ及びレジスタマークＥをベースフィルムＦ上に部分的に蒸着し、その他の領域（透明部Ｆ）を透明にした蒸着フィルムＧ（以下、部分箔貼着フィルムという。）においては、刻印Ｈの大きさで箔押しした場合、下部又は上部から光を透過させても、図柄箔Ｄが抜け落ちた領域とそれと隣接する領域（透明部Ｆ）とが透明であるため、図柄箔Ｄが抜け落ちた部分の面積を測定することができないため、箔押しの検査できないという問題があった。更に、前記箔貼付方法又は装置は、箔押し機にカメラを増設するため、箔押し機にこれを収納するためのスペースに余裕がないと取付けが不可能であり、また、これら従来の箔押し機においては、箔押しの数量管理が行われていない、という問題点があった。
【０００６】
【発明が解決しようとする課題】
本発明は前記問題点を解消するもので、本発明の目的は、全面箔貼着フィルム又は部分箔貼着フィルムの何れを使用した場合にも、夫々の枚葉紙に図柄箔が箔押しされているか否かの箔押し状態判定及び箔押し前の箔貼着フィルムに図柄箔及びレジスタマークが存在するか否かの箔検査を確実に行うと共に、箔押し状態判定良好の数、箔押し部に供給されるレジスタマークと箔図柄の数量、箔押し後の箔抜けした箔図柄と対応するレジスタマークの数量等の数量管理を確実に行うことである。

本発明は、枚葉紙に偽造防止画像情報となるホログラム等の光学的視認変化素子（オプティカル・バリアブル・デバイス（ＯＶＤ））を形成した図柄箔を箔押しする箔押し機に関するものであり、箔押し機１は、図１に示すように、給紙部２、箔押し部３、排紙部４、箔搬送部５からなる主な機構に、箔押し状態判定機構８Ａと、箔検査機構８Ｂと、箔押し状態良好の数、箔押し前、後のレジスタマーク及び図柄箔の数、を夫々計数する計数手段と、前記箔押し状態判定情報、箔検査情報及び前記各種計数情報をロット毎に収集管理するデータ収集管理機構８Ｃとを具備する検査・管理部８が付加したものである。
【００２２】

【００２５】

【００２６】

【００２７】
本発明の箔押し機１は、箔押し状態判定機構８Ａと、箔検査機構８Ｂと、箔押し状態良好の数、箔押し前、後のレジスタマーク及び図柄箔の数、を夫々計数する計数手段と、前記箔押し状態判定情報、箔検査情報及び前記各種計数情報をロット毎に収集管理するデータ収集管理機構８Ｃとを具備する検査・管理部８を設けた点に特徴を有するものである。
【００２８】
先ず、箔押し状態判定機構８Ａについて説明する。
箔押し状態判定機構８Ａは箔押し部において箔押しが確実に行われたか否かを判定するもので、図４に示すように、箔押し部３で箔押しされた後（以下、箔押し後という。）の箔貼着フィルムＧにレジスタマークＥが存在するか否かを光センサーＳ３及びレベル判定回路８ａからなる箔押し後レジスタマーク検出手段で検出すると共に、箔押し後の箔貼着フィルムＧに図柄箔Ｄが存在するか否かを光センサーＳ４及びレベル判定回路８ａからなる箔押し後図柄箔検出手段で検出し、箔押し後レジスタマーク検出手段がレジスタマークの存在（例えば、ＮＯＴ回路出力が「１」）を、前記箔押し後図柄箔検出手段が図柄箔Ｄの不存在（レベル判定回路８ａの出力が「１」）を、夫々検出した（例えば、ＡＮＤ回路出力「１」の）場合に、枚葉紙の所定の位置に図柄箔が箔押しされたものと判定し、このような箔押し状態が良好の場合には、箔押し動作及び箔搬送動作を継続する。一方、レジスタマークの不存在又は図柄箔Ｄの存在を検出した（ＡＮＤ回路出力「０」）場合は、箔は不良であると判定して機械（箔搬送動作及び箔押し動作）を停止する。
【００２９】
箔押し後レジスタマーク検出手段は、箔押し後の箔貼着フィルムＧのレジスタマークＥの位置に光を照射するレジスタマーク用光源Ｌ３と、レジスタマークＥの位置で透過又は反射したレジスタマーク用光源Ｌ３からの光を検出するレジスタマーク用光センサーＳ３とからなり、箔押し動作が正常に行われた場合には、箔押し後もレジスタマークＥはそのまま存在するので、レジスタマーク用光センサーＳ３の出力は透過光の場合は低出力、反射光の場合は高出力となる。
【００３０】
箔押し後図柄箔検出手段は、箔押し後の箔貼着フィルムＧの図柄箔Ｄの位置に光を照射する図柄箔用光源Ｌ４と、図柄箔Ｄの位置で透過又は反射した図柄箔用光源Ｌ４からの光を検出する図柄箔用光センサーＳ４とからなり、箔押し動作が正常に行われた場合には、箔押しにより図柄箔Ｄは箔抜けするので、箔押し後は図柄箔Ｄは存在しないので、図柄箔用光センサーＳ４の出力は透過光の場合は高出力、反射光の場合は低出力となる。
【００３１】
次に、前記本発明の特徴である箔検査機構について説明する。箔検査機構８Ｂは箔押し前の箔貼着フィルムＧの所定の位置にレジスタマークＥ及び図柄箔Ｄが存在するか否かを検査するもので、図４に示すように、箔押し部に搬送される箔押し前の箔貼着フィルムＧのレジスタマークＥの存在を検出する光センサーＳ１及びレベル判定回路８ａからなる箔押し前レジスタマーク検出手段と、箔押し部に搬送される箔押し前の箔貼着フィルムＧの図柄箔Ｄの存在を検出する光センサーＳ２及びレベル判定回路８ａからなる箔押し前図柄箔検出手段とからなり、前記箔押し前レジスタマーク検出手段がレジスタマークＥの存在（ＮＯＴ回路出力が「１」）を、前記箔押し前図柄箔検出手段が図柄箔Ｄの存在（ＮＯＴ回路出力が「１」）を夫々検出した場合（ＡＮＤ回路出力「１」）は、箔は良好であると判定して箔搬送動作を継続し、何れか一方が不存在（ＡＮＤ回路出力「０」）の場合は、箔は不良であると判定して、機械（箔搬送動作及び箔押し動作）を停止する。
【００３２】
前記箔押し前レジスタマーク検出手段は、箔押し前の箔貼着フィルムＧのレジスタマークＥの位置に光を照射するレジスタマーク用光源Ｌ１と、レジスタマークＥの位置で透過又は反射したレジスタマーク用光源Ｌ１からの光を検出するレジスタマーク用光センサーＳ１とからなり、箔貼着フィルムＧが正常である場合には、レジスタマークＥは存在するので、レジスタマーク用光センサーＳ１の出力は透過光の場合は低出力、反射光の場合は高出力となる。
【００３３】
前記箔押し前図柄箔検出手段は、箔押し前の箔貼着フィルムＧの図柄箔Ｄの位置に光を照射する図柄箔用光源Ｌ２と、図柄箔Ｄの位置で透過又は反射した図柄箔用光源Ｌ２からの光を検出する図柄箔用光センサーＳ２とからなり、箔貼着フィルムＧが正常である場合には、図柄箔Ｄは存在するので、図柄箔用光センサーＳ２の出力は透過光の場合は低出力、反射光の場合は高出力となる。
【００３４】
前記光源Ｌ１〜Ｌ４として、白熱管、蛍光管、各種放電管、発光ダーオード、レーザー光源、赤外線光源等を、前記光センサーＳ１〜Ｓ４として、光電管、フォトダイオード、フォトトランジスタ等を用いることができる。
【００３５】
前記箔押し状態判定機構８Ａの他の実施例を以下に示す。図５に示すように、箔押し部３に投入前（以下、箔押し前という。）の箔貼着フィルムＧに図柄箔Ｄが存在するか否かを、箔押し前の図柄箔Ｄの位置で透過（又は反射）した図柄箔用光源Ｌ２からの光を図柄箔用光センサーＳ２からなる箔押し前図柄箔検出手段（図示省略。）で検出し、前記箔押し部３で箔押しされた後（以下、箔押し後という。）の箔貼着フィルムＧに図柄箔Ｄが存在するか否かを、箔押し後の図柄箔Ｄの位置で透過（又は反射）した図柄箔用光源Ｌ４からの光を図柄箔用光センサーＳ４からなる箔押し後（第２の）図柄箔検出手段（図示省略。）で検出し、箔押し前の図柄箔検出手段が図柄箔Ｄの存在を、箔押し後図柄箔検出手段が図柄箔Ｄの不存在を、夫々検出した時に、枚葉紙６の所定の位置に図柄箔Ｄが箔押し（貼着）されたものと判定する。光センサーＳ２の出力の高低をレベル判定回路８ａでレベル判定（透過光では、低出力の場合は「０」、高出力の場合は「１」）し、レベル判定出力をＮＯＴ回路で反転させた後、これを遅延回路８ｃで遅延させて光センサーＳ２の出力と揃える。そして、光センサーＳ３の出力の高低をレベル判定回路８ａでレベル判定（透過光では、低出力の場合は「０」、高出力の場合は「１」）し、この光センサーＳ３のレベル判定出力信号と前記光センサーＳ２のレベル判定出力を反転、遅延させた出力信号をＡＮＤ回路８ｄで論理演算することにより、箔押し前の図柄箔Ｄからの透過光を受光した光センサーＳ２のレベル判定出力が低出力「０」で、箔押し後の図柄箔Ｄからの透過光を受光した光センサーＳ４のレベル判定出力が高出力「１」の場合にのみ、箔押し状態は「良好」と判定する。
【００３６】
なお、図５に示す箔押し状態判定機構の変形例を図６に示す。この箔押し状態判定機構８Ａは、光センサーＳ３のレベル判定回路出力信号と、光センサーＳ４のレベル判定回路出力信号とを夫々レジスタ８ｃ’等の一時保持手段に保持した後、図５の箔押し状態判定機構と同様にＡＮＤ回路８ｄで論理演算して判定するものである。
【００３７】
本発明の検査・管理部８においては、図４に示すように、箔押し前レジスタマーク（存在の）の検出信号である光センサーＳ１のレベル判定回路出力信号、箔押し前図柄箔（存在の）の検出信号である光センサーＳ２のレベル判定回路出力信号、箔押し後レジスタマーク（存在の）の検出信号である光センサーＳ３のレベル判定回路出力信号、箔押し後図柄箔（不存在の）の検出信号である光センサーＳ４のレベル判定回路出力信号及び箔押し状態判定機構８Ａにより箔押し状態「良好」の信号を、夫々計数回路８ｅで計数して、箔押し前、後でのレジスタマーク及び図柄箔の数及び箔押し状態「良好」の数を夫々計数回路８ｅで算出し、これら計数値、箔押し状態判定機構８Ａの判定情報及び箔検査機構８Ｂの箔検査情報等をロット毎にデータ収集・管理機構８Ｃで、収集管理して、必要に応じて、表示部９に表示又はプリントアウトする。なお、この表示部９は、操作卓上の表示部と兼用させてもよいし、独立して設けてもよい。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a foil stamping machine for stamping a foil having an optically variable device (OVD) such as a hologram formed on a sheet of paper.
[0002]
[Prior art]
2. Description of the Related Art In recent years, holograms are stamped on valuable printed matter such as banknotes, securities, passports, etc., which require the most security, as represented by, for example, euro notes. Also, holograms are now stamped on various credit cards, IC cards, gift certificates, admission tickets, and the like, and there are a wide variety of hologram foil stamping products. The reason why holograms are used in many of these valuable products is that holograms have the property that their images and colors change significantly when the viewing angle is changed, so that anyone can easily determine the authenticity, and This is because there is an advantage that forgery is difficult.
[0003]
For holograms, techniques have also been developed in which the diffraction grating on the foil surface layer is devised to make the optical change more dynamic and to provide hidden information. On the other hand, as shown in FIG. 7, a symbol foil C made of a metal foil on which a forgery prevention information symbol such as a hologram that is visually visually changed is provided, and the symbol foil C is provided corresponding to the symbol foil C, and the position thereof is set. There is a foil stamping machine for forming a pair of register marks (or timing marks) B for designation and for foil stamping using a foil sticking film roll A formed at a certain interval. As shown in FIG. 11, the register mark B is read by an optical sensor, and only the design foil C is pressed on a base material such as paper or card by a press section of a foil press machine in accordance with the read timing, whereby the design foil C is obtained. Has the advantage that it can always be stamped in a fixed position.
[0004]
As shown in FIG. 11, the main mechanism of the foil pressing machine includes a paper feeding unit 2, a foil pressing unit 3, a paper discharging unit 4, and a foil feeding (conveying) unit 5. Specifically, first, the papers 6 are taken out one by one from the stack of the papers 6 and the like serving as the base material in the paper feeding unit 2 and transported to the foil stamping unit 3. On the other hand, in the foil feeding (conveying) section 5, the foil sticking film roll A is attached to the foil input section 5a, and after the foil is conveyed and passed through the foil pressing section 3, it is wound by the foil rewinding section 5b. In the foil pressing unit 3, the paper 6 transported from the paper feed unit 2 and the foil transported by the foil loading unit 5a face each other, and a convex engraving is formed on the fixing plate 3a installed above these. The heating plate is heated at a high temperature, and the pressurizing plate 3b disposed below these members repeats a vertical movement operation. When the pressing plate 3b moves upward, the paper 6 and the foil, in particular, the hologram design C portion are heated and pressed. Then, the foil design is affixed to the paper 6, and the paper 6 to which the foil design is affixed is sequentially discharged and stacked on the paper discharge unit 4. On the other hand, the foil after the foil design has been pressed is wound up by the foil rewinding section 5b.
[0005]
On the other hand, there is a foil-pressing machine of the type which presses a design foil without providing a register mark (or timing mark) B for designating the position of the foil as described above.
Conventionally, in order to check the quality of the paper to which the foil has been attached by the foil pressing machine, the paper discharged to the paper output unit 4 has been extracted and visually inspected by hand to confirm the adhesion quality. In order to improve such a sticking quality inspection by hand, a method or an apparatus for providing a foil sticking inspection mechanism in a foil sticking machine (for example, see JP-A-2002-39729) has been proposed. However, as shown in FIG. 10, this method or apparatus measures the area of the part where the design foil C of the remaining foil after the foil pressing has fallen off by irradiating light, and measures the area within a predetermined range. In order to determine whether or not the foil pressing has been performed reliably, as shown in FIG. 8, as shown in FIG. In this case, the design foil D and the register mark E shown in FIG. 9 are partially deposited on the base film F, and the other areas (the transparent portions F) are transparent. In the case of the vapor-deposited film G (hereinafter, referred to as a partial foil sticking film), when the foil is pressed by the size of the stamp H, even if light is transmitted from the lower part or the upper part, the area where the design foil D falls off and adjacent thereto. Area (transparent part F) Because it is, it is not possible to measure the area of a portion symbol foil D fell out, there is a problem that can not be inspected for foil stamping. Furthermore, since the above-mentioned foil sticking method or apparatus adds a camera to the foil stamping machine, it is impossible to mount the foil stamping machine if there is not enough space for accommodating the camera, and in these conventional foil stamping machines, However, there is a problem that the quantity control of the foil stamping is not performed.

When the foil-pressing operation is performed normally, the design foil D is removed by the foil-pressing operation, and the design foil D does not exist after the foil-pressing. The output of the foil light sensor S4 is high in the case of transmitted light and low in the case of reflected light.
[0031]
Next, the foil inspection mechanism which is a feature of the present invention will be described. The foil inspection mechanism 8B inspects whether or not the register mark E and the design foil D are present at predetermined positions of the foil bonding film G before the foil pressing, and is conveyed to the foil pressing portion as shown in FIG. The pre-foil-register register mark detecting means including the optical sensor S1 for detecting the presence of the register mark E of the foil-bonded film G before the foil pressing and the level determination circuit 8a, It consists of a pre-foil stamping pattern foil detecting means comprising an optical sensor S2 for detecting the presence of the pattern foil D and a level judging circuit 8a, wherein the register mark detecting means before the foil pressing has the register mark E (NOT circuit output is "1").

The light from the pattern foil light source L4 transmitted (or reflected) at the position of the pattern foil D after the foil pressing is determined as to whether or not the pattern foil D is present in the foil sticking film G). After the foil pressing in step S4, the (second) pattern foil detecting means (not shown) detects the pattern foil, the pattern foil detecting means before the foil pressing detects the presence of the pattern foil D, and the pattern foil detecting means after the foil pressing causes the pattern foil D not to be detected. When the presence is detected respectively, the design foil D is pressed at a predetermined position of the sheet 6 ( Judged to have been deposited). The level of the output of the optical sensor S2 is determined by the level determination circuit 8a ("0" for transmitted light, "1" for low output, and "1" for high output) of the transmitted light, and the level determination output is inverted by the NOT circuit. Thereafter, this is delayed by the delay circuit 8c to make it equal to the output of the optical sensor S2. The level of the output of the optical sensor S3 is determined by the level determination circuit 8a ("0" for transmitted light, "1" for low output, and "1" for high output) with the level determination circuit 8a. By performing a logical operation on the signal and the output signal obtained by inverting and delaying the level determination output of the optical sensor S2 in the AND circuit 8d, the level determination output of the optical sensor S2 that has received the transmitted light from the design foil D before the foil pressing is obtained. The foil pressing state is determined to be "good" only when the level determination output of the optical sensor S4 that has received the transmitted light from the design foil D after the foil pressing at low output "0" is high output "1".
