JP-A-8-207247

しかしながら、印刷直後でインキがまだ用紙に十分馴染んでいない状態で印刷された用紙を乾燥させると、印刷面の光沢が出にくく、印刷物としての仕上がりに問題があった。   However, when the printed paper is dried immediately after printing in a state where the ink is not sufficiently familiar with the paper, the printed surface is less glossy and there is a problem in the finished product.

本発明は前述の問題に鑑み、乾燥部を有する印刷機において、乾燥部による乾燥により印刷物の光沢に影響を与えることがなく、良好な仕上がりの印刷物を得ることのできる印刷機を提供することをその課題とする。   In view of the above-mentioned problems, the present invention provides a printing machine having a drying unit that can obtain a printed material with a good finish without affecting the gloss of the printed material by drying by the drying unit. Let that be the issue.

前記課題を解決するために、本発明は、給紙部Ａと、インキローラー群４から供給されるインキを版胴１を介してゴム胴２に転写し、該ゴム胴２と共に該給紙部Ａから搬送導入される用紙Ｐを挟持して搬送する圧胴３とを有する印刷部Ｂと、該印刷部Ｂで印刷された用紙Ｐを乾燥させる乾燥部Ｔとを有する印刷機において、該印刷部Ｂと該乾燥部Ｔとの間に用紙Ｐの印刷面が当接する少なくとも１つのならし胴２０を設けたことを特徴としている。   In order to solve the above-described problems, the present invention transfers the ink supplied from the paper feeding unit A and the ink roller group 4 to the rubber cylinder 2 through the plate cylinder 1, and the paper feeding unit together with the rubber cylinder 2. In a printing machine having a printing unit B having an impression cylinder 3 that sandwiches and conveys a sheet P conveyed from A, and a drying unit T that dries the sheet P printed by the printing unit B. Between the part B and the drying part T, at least one leveling cylinder 20 with which the printing surface of the paper P abuts is provided.

本発明の請求項１記載の印刷機によれば、印刷部と乾燥部との間には用紙の印刷面が当接する少なくとも１つのならし胴を設けたので、乾燥部による乾燥により印刷物の光沢に影響を与えることがなく、良好な仕上がりの印刷物を得ることのできる印刷機を実現することができる。   According to the printing machine of the first aspect of the present invention, since at least one leveling cylinder with which the printing surface of the paper abuts is provided between the printing unit and the drying unit, the gloss of the printed matter is obtained by drying by the drying unit. Thus, it is possible to realize a printing machine that can obtain a printed matter with a good finish without affecting the quality.

本発明の実施形態による印刷機について図１〜３に基づき説明する。図１の概略全体図に示す通り、本実施例に係る印刷機は枚葉オフセット印刷機である。この印刷機は、紙積み台からフィーダ装置や用紙分離装置等により一枚ずつ印刷用紙としての枚葉紙Ｐを送り出すための給紙部Ａと、この給紙部Ａからの枚葉紙Ｐに印刷を行うための印刷部Ｂと、枚葉紙Ｐを排紙するための排紙部Ｃを備えている。ここで印刷部Ｂは、５色の印刷が行えるように５台の印刷ユニット５を備えた印刷部Ｂとしているが、５色以外の色、つまり１色又は２色以上の印刷が行える印刷部であってもよい。又、前記排紙部Ｃは、グリッパを備えるチェーン搬送装置１２にて構成しているが、この排紙部Ｃのない印刷機であってもよいし、又、印刷機を構成する各部の具体的な構成は図に示されるものに限定されるものではない。   A printing press according to an embodiment of the present invention will be described with reference to FIGS. As shown in the schematic overall view of FIG. 1, the printing press according to this embodiment is a sheet-fed offset printing press. The printing machine includes a sheet feeding unit A for sending out sheets P as printing sheets one by one from a sheet stacking unit by a feeder device, a sheet separating device, and the like, and a sheet P from the sheet feeding unit A. A printing unit B for printing and a paper discharge unit C for discharging the sheet P are provided. Here, the printing unit B is a printing unit B including five printing units 5 so that five colors can be printed. However, the printing unit can print colors other than five colors, that is, one color or two or more colors. It may be. Further, although the paper discharge unit C is constituted by the chain conveying device 12 having a gripper, the paper discharge unit C may be a printing machine without the paper discharge unit C, or the specifics of each part constituting the printing machine. The specific configuration is not limited to that shown in the figure.

前記印刷ユニット５は、版胴１とゴム胴２とインキローラー群４、そして圧胴３と渡し胴６とを備えている。図示していないが、前記胴３、６のそれぞれには、送り出されてきた枚葉紙Ｐを爪台と爪とで把持するグリッパを円周方向の２箇所（１箇所又は３箇所以上でもよい）に備えている。符号７は給紙胴であり、フィーダーボード８、口板９上を搬送される枚葉紙Ｐをスイングアーム１０から受け取り、圧胴３に渡す役割を果たす。給紙胴７、スイングアーム１０にも前記の爪台と爪が設けられている。   The printing unit 5 includes a plate cylinder 1, a rubber cylinder 2, an ink roller group 4, an impression cylinder 3, and a transfer cylinder 6. Although not shown, each of the cylinders 3 and 6 has two grippers (one or three or more in the circumferential direction) for gripping the fed sheet P with the claw base and the claw. ) Reference numeral 7 denotes a paper feed cylinder which plays a role of receiving the sheet P conveyed on the feeder board 8 and the mouth plate 9 from the swing arm 10 and transferring it to the impression cylinder 3. The feeding cylinder 7 and the swing arm 10 are also provided with the claw base and the claw.

印刷部の最終印刷ユニット５と排紙部Ｃとの間には乾燥部と、本発明に関するならし胴とが設けられている。すなわち、最終印刷ユニット５の圧胴３により搬送された枚葉紙Ｐはならし胴２０に受け渡される。ならし胴２０は円筒形状で、枚葉紙Ｐの印刷された印刷面がその円筒面に当接するよう構成されている。よって、枚葉紙Ｐの印刷された印刷面はならし胴２０に当接することとなり、インキが用紙に十分に馴染むこととなる。このインキが馴染んだ状態の枚葉紙Ｐはならし胴２０から乾燥用圧胴１１に受け渡される。乾燥用圧胴１１の上部には乾燥部Ｔが設けられている。   Between the final printing unit 5 of the printing unit and the paper discharge unit C, a drying unit and a leveling cylinder related to the present invention are provided. That is, the sheet P conveyed by the impression cylinder 3 of the final printing unit 5 is delivered to the leveling cylinder 20. The leveling cylinder 20 has a cylindrical shape and is configured such that the printing surface on which the sheet P is printed comes into contact with the cylindrical surface. Therefore, the printing surface on which the sheet P is printed comes into contact with the leveling cylinder 20, and the ink becomes sufficiently familiar with the paper. The sheet P in a state in which the ink is familiar is transferred from the leveling cylinder 20 to the drying impression cylinder 11. A drying section T is provided on the top of the drying impression cylinder 11.

乾燥部Ｔは具体的には紫外線照射部であり、図２にも示すように、乾燥用圧胴１１の表面にほぼ直交する方向に照射軸を有する多数の発光ダイオード２１を備え、それら発光ダイオード２１が乾燥用圧胴１１の上方に配置されている。これら多数の発光ダイオード２１は基板２２に備えられており、枚葉紙Ｐの幅方向に多数配置されている。   Specifically, the drying unit T is an ultraviolet irradiation unit, and as shown in FIG. 2, the drying unit T includes a plurality of light emitting diodes 21 having irradiation axes in a direction substantially orthogonal to the surface of the drying impression cylinder 11. 21 is disposed above the drying impression cylinder 11. A large number of these light emitting diodes 21 are provided on the substrate 22 and are arranged in the width direction of the sheet P.

印刷部Ｂにて印刷された枚葉紙Ｐは最終印刷ユニット５の圧胴３からならし胴２０に渡され、枚葉紙Ｐの印刷面がならし胴２０に当接してインキが用紙に十分馴染むこととなる。そしてならし胴２０から乾燥用圧胴１１に受け渡された枚葉紙Ｐは乾燥部Ｔにて乾燥され、排紙部Ｃのチェーン搬送装置１２に受け渡される。このようにして印刷される枚葉紙Ｐは光沢を損なうことがなく、良好な仕上がりとなる。   The sheet P printed by the printing unit B is transferred from the impression cylinder 3 of the final printing unit 5 to the leveling cylinder 20, and the printing surface of the sheet P contacts the leveling cylinder 20 so that the ink is applied to the sheet. You will become familiar with it. The sheet P delivered from the leveling cylinder 20 to the drying impression cylinder 11 is dried by the drying unit T and delivered to the chain conveying device 12 of the paper discharge unit C. The sheet P printed in this way has a good finish without impairing the gloss.

図３は本発明の他の実施例を示す枚葉オフセット印刷機の概略側面図である。本実施例では、最終印刷ユニット５ｅの圧胴３に乾燥部Ｔが近接している。この場合、最終印刷ユニット５ｅのゴム胴２を胴抜きすることにより、最終印刷ユニット５ｅでは印刷を行わないように設定する。すると、印刷ユニット５ｄが最終印刷ユニットとなり、印刷ユニット５ｄと印刷ユニット５ｅにそれぞれ設けられた渡し胴２０がならし胴としての機能を奏することとなる。   FIG. 3 is a schematic side view of a sheet-fed offset printing press showing another embodiment of the present invention. In this embodiment, the drying unit T is close to the impression cylinder 3 of the final printing unit 5e. In this case, the final printing unit 5e is set not to perform printing by removing the rubber cylinder 2 of the final printing unit 5e. Then, the printing unit 5d becomes the final printing unit, and the transfer cylinder 20 provided in each of the printing unit 5d and the printing unit 5e functions as a leveling cylinder.

本発明にかかる印刷機のならし胴は、上述した実施の形態に限定されず、特許請求の範囲で記載した範囲で種々の変形や改良が可能である。例えば、前述の実施例では、枚葉オフセット印刷機であったが、これに限定されず、輪転紙オフセット式印刷機やインクジェット式印刷機、またフレキソ印刷機のようなものであってもよい。   The leveling cylinder of the printing press according to the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope described in the claims. For example, in the above-described embodiment, the sheet-fed offset printing machine is used. However, the present invention is not limited to this, and a rotary paper offset printing machine, an ink jet printing machine, or a flexographic printing machine may be used.

本発明に係る印刷機は、乾燥部を有する印刷機において極めて有用である。   The printing press according to the present invention is extremely useful in a printing press having a drying section.
