Description

本発明は、印刷技術の分野に関するもので、特に、枚葉式フレキソ印刷機に関する。   The present invention relates to the field of printing technology, and more particularly to a sheet-fed flexographic printing machine.

既存のフレキソ印刷機、特に両面フレキソ印刷機の場合は、生産性向上の要求に適応させるために、毎回印刷直後に、印刷面へのインクの乾燥硬化をを行う必要があり、それにより次の段階または次の面の印刷作業が行われることができる。既存の印刷物の高速乾燥技術の大部分は、熱風、赤外線また紫外線による乾燥硬化等の原理を採用して、印刷物の高速乾燥を実現している。前記乾燥方法は、すべての印刷物の表面に熱影響を与える可能性があり、軽い場合は、印刷物のある一側の表面の温度の上昇に伴いやや浮き上がる現象を引き起こし、酷い場合は、印刷物の顕著な変形を引き起し、特殊な場合には、印刷物のコークスまたは燃焼を引き起こす可能性がある。なお、印刷生産品質に対する要求が改善し続けていくに従って、使用者により、印刷装置へのオンライン品質検査システムの配置に対しての要求が提案されており、既存のフレキソ印刷機は、まだ印刷物の品質のオンライン検査システムの配置上では、依然として不十分である。   In the case of existing flexographic printing machines, especially double-sided flexographic printing machines, it is necessary to dry and cure the ink on the printing surface immediately after printing in order to adapt to the demand for productivity improvement. A stage or next side printing operation can be performed. Most of the existing high-speed drying techniques for printed materials employ a principle such as drying and curing by hot air, infrared rays or ultraviolet rays to achieve high-speed drying of printed materials. The drying method may have a thermal effect on the surface of all printed materials, and if it is light, it causes a phenomenon that it slightly floats as the temperature of one surface of the printed material increases. In some special cases and can cause coke or burning of the print. In addition, as the demand for print production quality continues to improve, the demand for the placement of the online quality inspection system in the printing device has been proposed by the user. The placement of quality online inspection systems is still insufficient.

図４は、既存の両面フレキソ印刷機のフローチャートであり、当該フローチャートにおいて、印刷物の両面に対応する二つの印刷のカラーグループは順次に接続されている。ここで、第１面（Ａ面）の印刷を完成するとともに乾燥装置でインク乾燥硬化を行ってから、すぐ他面（Ｂ面）の印刷及び乾燥硬化を行い、そして検査ローラー内でそれぞれ二つの印刷面の品質検査を行い、当該印刷構造には、印刷物の連続的な乾燥で熱の蓄積の問題が存在し、また印刷物の過熱によって引き起こされる変形などの問題は、印刷品質に影響を与え、また印刷物をきちんと収集されることに役立たない。なお、当該流れを採用した印刷機の機械構造において、印刷物の両面のオンライン検査は、二回の印刷のすべてが終わってから行われ、このように第１面の印刷で発生された品質問題は、第２面の印刷を完了した後にフィードバックされ、品質制御への適時性は十分ではない。   FIG. 4 is a flowchart of an existing double-sided flexographic printing machine, in which two printing color groups corresponding to both sides of the printed material are sequentially connected. Here, after the printing on the first side (A side) is completed and the ink is dry-cured with a drying device, the other side (B-side) is printed and dried and cured, and each of the two in the inspection roller. Inspecting the quality of the printed surface, the print structure has a problem of heat accumulation due to continuous drying of the printed matter, and problems such as deformation caused by overheating of the printed matter affect the print quality, Also, it does not help to properly collect printed matter. In the mechanical structure of a printing machine that employs this flow, the online inspection of both sides of the printed material is performed after all of the two printings are finished. Thus, the quality problem that has occurred in the printing of the first surface is as follows. The feedback is made after the printing of the second side is completed, and the timeliness for quality control is not sufficient.

図５は、既存の両面フレキソ印刷機の印刷ユニットローラーの配列構造の模式図であり、当該印刷ユニットローラーの配列構造は図４で示される印刷の流れに適応され、当該フレキソ印刷機は、印刷物の両面に連続的に印刷する方法を使用したため、生産過程において、前記熱の蓄積の問題及び印刷物の品質制御への適時性の問題が存在する。   FIG. 5 is a schematic diagram of an arrangement structure of printing unit rollers of an existing double-sided flexographic printing machine, and the arrangement structure of the printing unit rollers is adapted to the flow of printing shown in FIG. In the production process, there is a problem of heat accumulation and a problem of timeliness for quality control of printed matter.

図２で示されるように、リンティングストックは、まず印刷用用紙搬送ローラーから第１圧胴１に伝送し、順次に第１フレキソ印刷用ローラー９及びフレキソ印刷ローラー１７を通過して、印刷物の第１面の２色のオーバープリンティングを完成し、そして第１印刷インク乾燥硬化装置１３でインクの乾燥硬化を行い、また第１印刷用用紙搬送ローラーI２で冷却処理を行い、第１印刷用用紙搬送ローラーII３により第２圧胴４に伝送され、他面の２色のオーバープリンティングを完成し、第２印刷インク乾燥硬化装置１４で当該面のインク乾燥硬化を完成し、そして第２印刷用用紙搬送ローラーI５及び第２印刷用用紙搬送ローラーII６により冷却させ、、最後に紙を出して印刷を完成させる。こと過程において、両面印刷は、それぞれ第１検査装置７及び第２検査装置８等を通過して品質検査及び制御を行うことによって、印刷物の品質を保障することができる。また、第１印刷ユニットの印刷工程の上流には、給紙装置１５が設置され、第２印刷ユニットの印刷工程の下流には、多列型紙集積装置１６が設置されている。給紙装置１５及び多列型紙集積装置１６を設置することによって、便利に大量の紙に印刷を行うことができる。 As shown in FIG. 2, the linting stock is first transmitted from the printing paper transport roller to the first impression cylinder 1, and then sequentially passes through the first flexographic printing roller 9 and the flexographic printing roller 17. The two-color overprinting on the first surface is completed, the ink is dried and cured by the first printing ink drying and curing device 13, and the cooling process is performed by the first printing paper transport roller I 2. It is transmitted to the second impression cylinder 4 by the transport roller II3, completes the two-color overprinting of the other surface, completes the ink drying and curing of the surface by the second printing ink drying and curing device 14, and the second printing paper Cooling is performed by the transport roller I5 and the second printing paper transport roller II6, and finally the paper is taken out to complete printing. In this process, the double-sided printing can guarantee the quality of the printed matter by performing quality inspection and control through the first inspection device 7 and the second inspection device 8, respectively. Further, a paper feeding device 15 is installed upstream of the printing process of the first printing unit, and a multi-row paper stacking device 16 is installed downstream of the printing process of the second printing unit. By installing the paper feeding device 15 and the multi-row paper stacking device 16, it is possible to print on a large amount of paper conveniently.
