The ink forming roller 6 and the printing plate 7 are
Is transferred onto the kneading roller 4 by the ink scraping device 8
Is provided, and the transfer of new ink from the ink fountain is promoted by scraping off the ink in the non-image area. Further, by cooling the ink by using the cooling device 9 in the ink fountain, it is possible to suppress the property change due to the frictional heat of the ink.
Description
【０００１】[0001]
本考案は、凹版インキのような降伏価の高いインキを用いる印刷機において 、インキ を転移させる発明に関するものである。 The present invention relates to an invention for transferring ink in a printing press using an ink having a high yield value, such as an intaglio ink.
【０００２】[0002]
従来のインキ供給装置においては、図１に示すように、ドクターブレード１ と第１ロ ーラ４の間のインキ壷２へインキ３を投入し、第１ローラ４の表面のインキを第 ２ローラ ５で均一に練りならして、第３ローラ６及び凹版版胴７に取り付けられた凹版版 面へと転 移させる。この機構においては、第１ローラ４から第３ローラ６へインキが転移 するとき 、第３ローラ６上にあるインキ皮膜は次の理由により、均一ではない。インキ転 移先であ る凹版版胴７の凹版版面には、画線部と非画線部があり、ローラ上の位置によっ てはイン キが凹版版面へ付着してもその次の転移先である用紙へ転移しない部分が存在す る。この 転移しない部分は第３ローラ６等による練り及び熱等からインキの酸化重合が促 進され乾 燥した状態になり印刷不良の原因となっていた。 In a conventional ink supply apparatus, as shown in FIG. 1, ink 3 is supplied to an ink fountain 2 between a doctor blade 1 and a first roller 4, and ink on the surface of a first roller 4 is supplied to a second roller. The mixture is uniformly kneaded in 5 and transferred to the third roller 6 and the intaglio plate surface attached to the intaglio plate cylinder 7. In this mechanism, when the ink is transferred from the first roller 4 to the third roller 6, the ink film on the third roller 6 is not uniform for the following reasons. The intaglio printing plate surface of the intaglio printing cylinder 7 to which the ink is transferred has an image portion and a non-image portion. Depending on the position on the roller, even if the ink adheres to the intaglio printing plate, the next transfer is performed. There is a part that does not transfer to the destination paper. The non-transferred portion was oxidized and polymerized by the kneading and heat of the third roller 6 or the like to promote the oxidation polymerization of the ink, resulting in a dry state, which resulted in poor printing.
【０００３】[0003]
インキ転移不良による、先刷りのオフセットインキ上への着肉不良、版面上 の非画線 部のインキを拭き取る際の拭き取り不良、印刷物の細い画線の画線切れ（転移不 良）状態 等の改善を図るものである。 Poor ink transfer due to poor ink transfer, poor wiping when wiping off ink on non-image areas on the plate, poor image quality (fine transfer failure) of thin objects on printed matter, etc. It is intended to improve.
【０００４】[0004]
本考案は、ローラ表面に残ったインキのうち、非画線部のインキを掻き取る ことによ りインキ壷から新しいインキの転移を促進し、また掻き取ったインキをインキ壷 へ戻す機 構。さらに、付帯して設けた冷却装置を用いてインキを冷却することによりロー ラ表面の インキの劣化を防ぐものである。 The present invention is a mechanism that promotes the transfer of new ink from the ink fountain by scraping the ink in the non-image area from the ink remaining on the roller surface, and returning the scraped ink to the ink fountain. Furthermore, the ink on the roller surface is prevented from deteriorating by cooling the ink using a cooling device provided in the attachment.

実施例によって本考案を更に詳細に説明するが、本考案はこの実施例によっ てなんら 制限されるものではない。 凹版インキのような降伏価の高いインキを用いる印刷機の本考案のインキ供給 装置は、 図２のように、インキ掻き取り装置８及びインキ冷却装置９が設けており、イン キ壺２に 投入されたインキ３が第１ローラ４及び第２ローラ５で均一に練りならされ第３ ローラ６ に転移し、凹版版胴７の凹版版面に転移する仕組みとなっている。そこで、第１ ローラ４ 上の非画線部に当たる部分に、インキ掻き取り装置８を取り設け、転移しないイ ンキを取 り除くことによりインキを第３ローラ６に供給することができる。一方、インキ 冷却装置 ９をドクターブレード１上に設けることでインキが摩擦熱による性状変化を抑え ることが できる。また、図３に示すように、インキ冷却装置９’は、中空の構造となって おり、水 が絶えず通水し冷却される。 The present invention will be described in more detail with reference to examples, but the present invention is not limited to the examples. As shown in FIG. 2, the ink supply device of the present invention of a printing press using an ink having a high yield value, such as an intaglio ink, is provided with an ink scraping device 8 and an ink cooling device 9 and is put into the ink jar 2. The applied ink 3 is uniformly kneaded by the first roller 4 and the second roller 5 and transferred to the third roller 6, and transferred to the intaglio plate surface of the intaglio plate cylinder 7. Therefore, an ink scraping device 8 is provided at a portion corresponding to the non-image area on the first roller 4, and ink that does not transfer can be removed to supply ink to the third roller 6. On the other hand, by providing the ink cooling device 9 on the doctor blade 1, it is possible to suppress the property change of the ink due to frictional heat. Further, as shown in FIG. 3, the ink cooling device 9 'has a hollow structure, in which water is constantly passed and cooled.
【０００６】[0006]
本考案により、凹版インキの転移向上が図られ、インキの安定供給が行える とともに 先刷りオフセットインキ上への着肉不良、拭き取り不良及び画線切れ等印刷不良 の発生を 防ぐことができる。また、掻き取ったインキがインキ壷へ戻るのでコストの低減 も図れる 。一方、摩擦熱によるインキの性状変化も抑えることができる。 According to the present invention, the transfer of the intaglio ink is improved, the ink can be supplied stably, and the occurrence of poor printing such as poor inking, poor wiping, and broken image on the preprinted offset ink can be prevented. In addition, since the scraped ink returns to the ink fountain, costs can be reduced. On the other hand, a change in the properties of the ink due to frictional heat can also be suppressed.
