刷物における継目の検知装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for detecting seams in printed matter that has a function of distinguishing between seams in printed matter and printed color marks, eye marks, etc.
インスタント食品、冷凍食品、或いはその他の
物品等の包装袋となる印刷物を印刷するにおいて

を施すことにより個々の包装品を製造することに
なる。 When printing printed matter that will be used as packaging bags for instant foods, frozen foods, or other goods, multiple sheets of web-like raw film are joined together with adhesive tape to form a roll, which is then mounted on a rotary printing machine. After the printing is finished, the paper is rolled up to form a rolled printed matter, which is then shipped as a product from a printing company to a food company or the like. Food companies and the like manufacture individual packaged products by loading printed matter onto a packaging machine, unwinding it one after another, and subjecting it to processing such as folding, filling, heat-sealing, and cutting.
このとき、巻取り印刷物の継目の部分にも印刷
が施されており、従つて、包装機に装填する前に
この部分を除去しなければ包装品に継目部分の印
刷物が混入することになる。 At this time, the seam portion of the rolled printed matter is also printed, and therefore, unless this portion is removed before loading into the packaging machine, the printed matter at the seam portion will be mixed into the packaged product.
これを防止するために、一般的に印刷終了後の
巻取り印刷物を巻返し機にて巻返し、巻返し過程
で各種検査を行うとともに継目部分を探し出し、
この部分をカツターナイフ等で切り取つて除去し
た後、その前後の印刷物を絵柄の繰り返しパター
ンが崩れないように絵柄と絵柄の間の余白部にて
接着テープでつなぎ合わせている。 In order to prevent this, generally after printing is completed, the rolled printed material is rewound using a rewinding machine, various inspections are performed during the rewinding process, and seams are detected.
After removing this part by cutting it out with a cutter knife or the like, the prints before and after it are joined together with adhesive tape in the margins between the pictures so that the repeating pattern of the picture does not collapse.
これにより、包装機での包装工程の際に直接包
装品の絵柄部分に継目が混入することをなくする
ことができるが、上記の如く、継目を有する巻き
取り印刷物から継目部分を除去するためには、ま
ず継目を検出することが必要となる。 This makes it possible to prevent the seam from getting mixed directly into the pattern of the packaged product during the packaging process in the packaging machine, but as mentioned above, it is possible to eliminate the seam from the rolled printed matter that has the seam. First, it is necessary to detect the seams.
これを自動的に行わしめるには巻返し機等で走
行している印刷物に光を照射し、継目部分の接着

量の差を読み取つて継目を検知する装置が考えら
れる。 To do this automatically, a rewinding machine or the like illuminates the running printed matter and detects the seam by reading the difference in the amount of reflected or transmitted light between the adhesive tape at the seam and the underlying film. A device can be considered.

巻取り印刷物の継目を検知することができる装置
を提供するものである。 However, if printing is done on film etc.
There is a printed pattern in the middle of the film, and eye marks, color marks, etc. are also printed on the side edges of the film, so a detection device that simply uses a photoelectric converter cannot detect the presence of the printed pattern. Even if you use the side edge of the film that does not have an eye mark, just like adhesive tape,
It also detects color marks and the like, so it cannot be used as a device for detecting seams in printed matter. The present invention has been made in view of the above-mentioned points, and includes a device for detecting seams of a rolled-up printed matter that is printed after joining a plurality of original films with an adhesive tape. , a device comprising means for distinguishing a printed mark such as an eye mark from a base film, and a means for distinguishing the adhesive tape from the printed mark, and capable of detecting a seam in a rolled printed matter by detecting the adhesive tape. This is what we provide.

ある。 When the printed matter 1 fed from the feeder section passes the third guide roller 4, the printed matter 1 is scanned by the photoelectric converter 8 and the pattern is converted into an electrical signal.
After the electric signal is amplified by the amplification circuit 9, the base film portion of the printed matter 1 is converted to H by the binarization circuit 10.
On the level, portions such as adhesive tapes and eye marks whose reflectance is lower than a certain appropriate amount than the base film are binarized into L level. In the binary signal, the L level portion corresponding to the tape is , and the L level portion corresponding to the eye mark is .

できる。 When the photoelectric converter 8 detects an adhesive tape, an eye mark, etc., the output of the edge detection circuit 11 becomes L level for several microseconds like a load signal, and the data output of the counter 12 becomes the preset switch 1.
The value set in step 3 will be used. The counter 12 counts the pulses of the clock signal only while the binarized signal is at the L level, and when it counts down from the value set by the preset switch 13 and reaches 0, the detection signal is equal to half a pulse of the clock signal. It becomes L level. The display circuit 14 outputs a signal to drive the alarm 15 when the detection signal becomes L level,
Alert the worker. By the way, the width of the adhesive tape and the eye mark is usually wide, so
For example, if the L level portion of the above binary signal is equivalent to 20 pulses of the clock signal, and the same is equivalent to 10 pulses, and the preset switch 13 is set to a value of 15, the detection signal output from the counter 12 will be The alarm 15 can be activated only when the adhesive tape is detected, because it is at the L level for half a pulse of the clock signal only during the counting period and remains at the H level during the counting period.
なお、ロータリーエンコーダー７で印刷物１の

事はない。 Note that since the speed of the printed matter 1 is indirectly measured by the rotary encoder 7, there will be no malfunction due to speed changes between the beginning and the end of winding the printed material 1.
このようにロータリーエンコーダー７を使用す
