Description

本発明は、製本の丁合工程における乱丁検出用マークの検出方法およびその方法が搭載されたマーク検出装置に関するものであり、さらに詳細には、刷本の端辺の所定の位置に施された乱丁検出用マークの有無を検出し、装架員(人手)の乗せ違いによる乱丁を事前に防止するための丁合工程における乱丁検出用マークの検出方法およびその装置に関するものである。   The present invention relates to a method for detecting an irregularity detection mark in a bookbinding collation process and a mark detection apparatus equipped with the method, and more specifically, applied to a predetermined position on the edge of a book. The present invention relates to a detection method and apparatus for detecting a disorderly mark in a collation process for detecting the presence or absence of a disorderly detection mark and preventing in advance a disorder due to a mounting person (manual hand) misplacement.

上記製本とは、印刷された刷本を順序に従ってとりまとめ、読みやすいように互いに接合して本とすることで、この製本の作業工程に同一の刷本(以下折り丁という))を揃えて積み重ね、積み重ねられた複数の折り丁群から順序に従って丁合する丁合工程がある。この同一の折り丁を揃えて積み重ね、丁合機に乗せる作業は装架員(人手)でなされ、この丁合機に積み重ねられた複数の刷本群から順序に従って丁合する丁合工程において、前記の丁合機に乗せる装架員(人手)の乗せ違い(別種の刷本群を乗せる)があると、一部に乱丁(本のページが乱れていることで、折り丁が順序不同に入り乱れて丁合されているもの)が発生することになる。   The above bookbinding means that the printed booklets are collected according to the order and joined together so that they are easy to read, and the same booklet (hereinafter referred to as the signature) is aligned and stacked in the bookbinding process. There is a collation process for collating according to an order from a plurality of stacked signature groups. The same signatures are stacked and stacked, and the work of putting them on the collating machine is done by a workman (manual), and in the collating process of collating according to the order from a plurality of print book groups stacked on this collating machine, If there is a misplacement of the crew member (manual) to be put on the collating machine (loading a different kind of printing book group), some of the books are out of order (the pages of the book are disturbed, so the signatures are out of order) Will occur).

従来、上記のような乱丁現象を事前に防止する対策の一つとして、例えば、図6(a)の概略斜視図に示すように、印刷された折り丁(10)の端辺に乱丁検出マーク(30)が施されていて、この乱丁検出マーク(30)が施された折り丁(10)が、図6(b)の側面図に示すように、装架員(人手)によって揃えられ、丁合機に積み重ねられて折り丁群(100)とするもので、このような折り丁群(100)を、側面から見ると、乱丁検出用マーク(30)が一定の位置に揃っているように施してある。   Conventionally, as one of the countermeasures for preventing the above-described disorder phenomenon in advance, for example, as shown in the schematic perspective view of FIG. 6A, a disorder detection mark is formed on the edge of the printed signature (10). As shown in the side view of FIG. 6 (b), the signature (10) to which (30) has been applied and this irregularity detection mark (30) has been aligned by a layman (manual), The signatures are stacked on the collating machine to form a signature group (100). When the signature group (100) is viewed from the side, the disorder detection marks (30) appear to be aligned at a certain position. It is given to.

このような折り丁群(100)が本の頁数に応じた複数の印刷柄が異なる折り丁群(100)として丁合機にセットされるが、このセット(折り丁(10)を乗せること)の際、例えば図6(c)の側面図に示すように、装架員(人手)の乗せ違い(別種の折り丁群(101)を乗せる)により、側面から見ると、乱丁検出用マーク(30)が一定の位置に揃っているもの(正常な状態)に対し、他の位置に乱丁検出用マーク(30)が見えるようになる。このように乱丁検出用マーク(30)が所定の位置にあるか否かを自動的に検出する乱丁検出マークの検出方法で、折り丁群(100)の下から30mm程度で長さ(N)が15mm程度の乱丁検出用マーク(30)が施されている所定の位置に、赤色LEDの直径3mm程度のスポット状ビーム(40)を照射し、その反射光量をセンサーで捉え、乱丁検出用マーク(30)の有無で検出する方法である。そこで、例えば図6(c)に示すように、装架員の乗せ違いにより別種の折り丁群(101)が混じった場合、折り丁群(100)の最下部にある折り丁(10)から丁合され、折り丁群(100)全体が下がってくると、底面からの高さ(H)30mm程度の位置に固定されているスポット状ビーム(40)が別種の折り丁群(101)にさしかかると、乱丁検出用マーク(30)が無いと判別され、丁合機が停止し、オペレーターがその旨を確認の上、別種の折り丁群(101)を取り除くようにする方法である。   Such a signature group (100) is set as a signature group (100) in which a plurality of printed patterns corresponding to the number of pages of the book are different, and this set (the signature (10) is placed) ), For example, as shown in the side view of FIG. 6 (c), the mark for detecting disorder will be detected when viewed from the side due to the wrong placement of the clerk (manual) (with another kind of signature group (101)). Where (30) is aligned at a certain position (normal state), the disorderly detection mark (30) can be seen at other positions. In this way, the detection method of the disorder detection mark that automatically detects whether or not the disorder detection mark (30) is in a predetermined position, the length (N) is about 30 mm from the bottom of the signature group (100). A spot-like beam (40) having a diameter of about 3 mm of a red LED is irradiated to a predetermined position where a mark for detecting disorder (30) of about 15 mm is applied, and the amount of reflected light is captured by a sensor. This is a method of detecting by the presence or absence of (30). Therefore, for example, as shown in FIG. 6 (c), when a different kind of signature group (101) is mixed due to a difference in placement of the clerk, the signature (10) at the bottom of the signature group (100) is removed. When collated and the entire signature group (100) is lowered, the spot beam (40) fixed at a position of about 30 mm in height (H) from the bottom surface becomes another kind of signature group (101). When this happens, it is determined that there is no irregularity detection mark (30), the collating machine is stopped, and the operator confirms that and then removes another type of signature group (101).

しかしながら、上記の赤色LEDのスポット状ビーム(40)の照射による乱丁検出用マーク(30)の検出方法では、例えば図4(a)の正面図に示すように、オフセット輪転印刷機による8頁(表裏16頁)の折り丁(12)の場合では、折り機で折られた折り丁が正常に確実に折られるようにするため、中央の折り目(12a)の部分に切り穴(パーフォレーション(14))を刻設し、この穴から中の空気が抜けるようにするが、このパーフォレーション(14)を乱丁検出用マーク(30)の真ん中に刻設するようになる
ので、これを折り目(12a)にしたがって折られた折り丁(12)は、図4(b)の正面図に示すように、このパーフォレーション(14)があるため、図6(c)に示す直径が3mm程度の小さいスポット状ビーム(40)では、長さ(N)が15mm程度と長い乱丁検出用マーク(30)に照射するようになるので、この乱丁検出用マーク(30)が無いと誤検知され、丁合機が停止するという問題点があり、この誤検知の度に微調整(センサーの感度を下げる)を行うため、検査(マークの検出)の信頼性が損なわれるという問題点があった。
However, in the detection method of the irregularity detection mark (30) by the irradiation of the red LED spot beam (40), for example, as shown in the front view of FIG. In the case of the signature (12) on the front and back pages 16), a cut hole (perforation (14)) is formed in the central fold (12a) in order to ensure that the signature folded by the folding machine is normally folded correctly. ) So that the air in the hole escapes from the hole, but this perforation (14) is engraved in the middle of the irregularity detection mark (30). Therefore, since the folded signature (12) has this perforation (14) as shown in the front view of FIG. 4 (b), a small spot having a diameter of about 3 mm shown in FIG. 6 (c). In the beam (40), the irregularity detection mark (30) having a length (N) as long as about 15 mm is irradiated, so that it is erroneously detected that the irregularity detection mark (30) is not present, and the collator is activated. There is a problem of stopping, and since fine adjustment (decreasing the sensitivity of the sensor) is performed each time this erroneous detection is performed, the reliability of inspection (mark detection) is impaired.

さらにまた、上記スポット状ビームの照射による乱丁検出用マークの検出方法では、スポット状ビームの反射光量(現在値)と感度(閾値)との差の把握ができず、さらに赤色LEDのスポット状ビーム及びそのセンサーの劣化(光量の低下等)の判別が困難というこのセンサーの保守管理の難かしさに問題点があった。   Furthermore, in the above-described detection method of the mark for detecting irregularity by the irradiation of the spot-like beam, the difference between the reflected light amount (current value) and the sensitivity (threshold value) of the spot-like beam cannot be grasped. In addition, there is a problem in the difficulty of the maintenance and management of the sensor, in which it is difficult to determine the deterioration of the sensor (a decrease in the amount of light, etc.).

本発明は、かかる従来技術の問題点を解決するものであり、その課題とするところは、製本の丁合工程における乱丁検出用マークの検出方法およびその方法が搭載されたマーク検出装置であって、折り丁の端辺の所定の位置に施された乱丁検出用マークの有無を検出し、装架員の乗せ違いによる乱丁を事前に防止するための丁合工程における乱丁検出用マークの検出方法およびその装置において、たとえ折り丁の折り目部分に施された乱丁検出用マークにパーフォレーションが刻設されていても、誤検知されることがなく確実に乱丁検出用マークを検出することができ、さらに該乱丁検出用マークに照射するビームの反射光量と感度の差が把握でき、かつビームとそのセンサーの劣化の判別が容易な、すなわち保守管理が容易な丁合工程における乱丁検出用マークの検出方法およびその装置を提供することにある。   The present invention solves the problems of the prior art, and the object of the present invention is a method for detecting a mark for detecting disorder in a bookbinding collation process and a mark detection apparatus equipped with the method. The detection method of the mark detection mark in the collation process for detecting the presence or absence of the mark detection mark applied at a predetermined position on the edge of the signature, and preventing in advance the error due to misplacement of the mounter And in the apparatus, even if the perforation is engraved on the mark for detecting the disorder on the crease part of the signature, it is possible to reliably detect the mark for detecting the disorder without being erroneously detected. In the collating process, the difference between the reflected light quantity and sensitivity of the beam irradiating the irregularity detection mark can be grasped, and the deterioration of the beam and its sensor can be easily distinguished, that is, maintenance management is easy.

従って本発明は、製本の乱丁を事前に防止する技術として、上記の如く丁合工程における乱丁検出用マークの検出方法およびその装置の提供は、優れた実用上の効果を発揮するものである。   Therefore, according to the present invention, as a technique for preventing bookbinding disorder in advance, the provision of a method for detecting a disorderly detection mark and a device therefor in the collation process as described above exhibit excellent practical effects.

以下本発明を実施するための最良の形態を図面を用いて詳細に説明する。   The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

本発明は、例えば図1の概略側面図に示すように、製本の作業工程に同一の折り丁(10)を揃えて積み重ね、積み重ねられた複数の折り丁群(100)から最下の折り丁(10)を順序に従って丁合する丁合工程において、この複数の折り丁群(100)から折り丁(10)の端辺の所定の位置に施された乱丁検出用マーク(30)の有無を検出し、装架員(人手)の折り丁(10)の積み重ね(乗せ)違いによる乱丁を事前に防止するための丁合工程における乱丁検出用マークの検出方法およびその装置に関するものである。   As shown in the schematic side view of FIG. 1, for example, the present invention arranges and stacks the same signatures (10) in the bookbinding process, and the lowermost signature from a plurality of folded signature groups (100). In the collating process of collating (10) according to the order, whether or not there is a disorder detection mark (30) applied to a predetermined position on the edge of the signature (10) from the plurality of signature groups (100). The present invention relates to a detection method and an apparatus for detecting a disorderly detection mark in a collation process for detecting in advance a disorder due to a difference in stacking (mounting) of signatures (10) of a crew member (manual).

そこで、上記請求項1に係る発明は、例えば図2(a)に示すように、端辺に乱丁検出用マーク(30)が施されている同一柄の折り丁(10)が積み重ねられた折り丁群(100)から乱丁検出用マーク(30)が所定の位置に在るか否かの検出を、図2(a)およびこの側面を表す図2(b)に示すように、横長の線形状レーザービーム(50)の照射とその反射光量を読み取るエリアタイプレーザーセンサー(52)によってなされる丁合工程における乱丁検出用マークの検出方法である。   Therefore, the invention according to claim 1 is a fold in which signatures (10) having the same pattern having the irregularity detection mark (30) on the end are stacked as shown in FIG. 2 (a), for example. As shown in FIG. 2 (a) and FIG. 2 (b) showing this side surface, the detection of whether or not the disorderly detection mark (30) is located at a predetermined position from the group (100) is a horizontally long line. This is a method for detecting an irregularity detection mark in a collation process performed by an area type laser sensor (52) that reads an irradiation of a shaped laser beam (50) and the amount of reflected light.

上記発明によれば、図2(a)に示すように、例えば13mm×0.8mmの横長の線形状レーザービーム(50)の照射で、15mm×2.0mmの横長の乱丁検出用マーク(30)全体を照射するようになるので、例えば図4(a)および図4(b)に示すような、たとえオフセット輪転印刷機による8頁(表裏16頁)の折り丁(12)の場合のように、この折り丁(12)の折り目(12a)部分に施された乱丁検出用マーク(30)
にパーフォレーション(14)が刻設されていても、図2(a)、(b)に示す上記のような横長の線形状レーザービーム(50)の照射とその反射光量により、誤検知されることがなくかつ感度の微調整をも必要とせず確実に乱丁検出用マーク(30)を検出することができる。
According to the above-described invention, as shown in FIG. 2A, for example, when a horizontally long laser beam (50) of 13 mm × 0.8 mm is irradiated, a 15 mm × 2.0 mm horizontally long irregular mark detection mark (30 ) Since the entire surface is irradiated, for example, as shown in FIGS. 4 (a) and 4 (b), the page (front and back 16 pages) signature (12) by an offset rotary printing press is used. In addition, the disorder detection mark (30) applied to the fold (12a) portion of the signature (12)
Even if the perforation (14) is engraved on the surface, it is erroneously detected by the irradiation of the horizontally long linear laser beam (50) as shown in FIGS. 2 (a) and 2 (b) and the amount of reflected light. In addition, the irregularity detection mark (30) can be reliably detected without requiring fine adjustment of sensitivity.

上記折り丁群(100)とエリアタイプレーザーセンサー(52)との距離(L)は、図2(a)に示すように、40mm程度が好ましく、その角度は0°から45°の範囲が好ましい。   As shown in FIG. 2A, the distance (L) between the signature group (100) and the area type laser sensor (52) is preferably about 40 mm, and the angle is preferably in the range of 0 ° to 45 °. .

上記乱丁検出用マーク(30)のサイズとしては、長さ×幅が15mm×2.0mm程度の黒色または黒褐色系の濃色系の目立つ色でなるものが好ましい。   The size of the irregularity detection mark (30) is preferably a black or black-brown dark color conspicuous color having a length x width of about 15 mm x 2.0 mm.

また、上記横長の線形状レーザービーム(50)のサイズとしては、13mm×0.5mmから13mm×2.4mmの範囲が好ましく、特にその長さは、乱丁検出用マーク(30)の長さ(N)近傍の13mm程度で、その幅は0.8mmに近い方が精度等の点からより好ましい。   In addition, the size of the horizontally long linear laser beam (50) is preferably in the range of 13 mm × 0.5 mm to 13 mm × 2.4 mm, and the length is particularly the length of the disorderly detection mark (30) ( N) About 13 mm in the vicinity, and the width is preferably closer to 0.8 mm from the viewpoint of accuracy and the like.

上記乱丁検出用マークの検出方法によれば、例えば図2(c)に示すように、折り丁群(100)に、装架員の乗せ違いにより別種の折り丁群(101)が混じった場合の丁合工程で、この折り丁群(100)の最下部にある折り丁(10)から丁合され、折り丁群(100)全体が下がってくると、一定の位置に固定されている横長の線形状レーザービーム(50)が乗せ違いによる別種の折り丁群(101)にさしかかると、乱丁検出用マーク(30)が無いと判別され、丁合機が停止し、オペレーターがその旨を確認の上、別種の折り丁群(101)を取り除くようにする方法であり、正常な位置に乱丁検出用マーク(30)が設けられている折り丁群(100)に横長の線形状レーザービーム(50)を照射している時に、乱丁検出用マーク(30)の部分にパーフォレーション(図示せず)があった場合でも、容易に確実に乱丁検出用マーク(30)が有ると判別できるようにした乱丁検出用マークの検出方法とすることができる。   According to the above-described method of detecting a mark for detecting disorder, for example, as shown in FIG. 2 (c), when the signature group (100) is mixed with another type of signature group (101) due to a difference in the placement of the mounter. In the collating process, when the signature group (100) at the bottom of the signature group (100) is collated, and the entire signature group (100) is lowered, it is fixed in a fixed position. When the line-shaped laser beam (50) reaches another type of signature group (101) due to misplacement, it is determined that there is no irregularity detection mark (30), the collator stops, and the operator confirms that fact. In addition, another type of signature group (101) is removed, and a horizontally long linear laser beam (100) is placed on the signature group (100) provided with a disorder detection mark (30) at a normal position. 50) Irradiation detection when irradiating Even when there is perforation (not shown) in the mark (30) portion, it is possible to provide a method for detecting a tampering detection mark so that it can be easily and reliably determined that the tampering detection mark (30) is present. .
