It is driven by a motor. Further, Patent Document 1 proposes that a printing plate having a plate cylinder driven by a dedicated motor performs a so-called cantilever support type exchange of a printing plate (fliegenden Druckplattenwechsel).
特許文献2は、枚葉紙印刷機の印刷装置において片持支承式で印刷プレートの交換を行うための特別な実施形態に関する。この枚葉紙印刷機の版胴は、枚葉紙印刷機の主駆動部から連結解除された上で個別駆動部または直接駆動部によって駆動される。このように、特許文献2では、片持支承式で印刷プレートの交換を行うために、対応の印刷装置のインキ装置および湿し装置をプレート胴から連結解除させ、その後静止させる、ということが提案されている。 Patent document 2 relates to a special embodiment for exchanging printing plates in a cantilevered manner in a printing apparatus of a sheet-fed printing machine. The plate cylinder of the sheet printing machine is driven by the individual driving unit or the direct driving unit after being disconnected from the main driving unit of the sheet printing machine. Thus, in Patent Document 2, in order to replace the printing plate in a cantilevered manner, it is proposed that the inking device and the dampening device of the corresponding printing device are disconnected from the plate cylinder and then stopped. Has been.
片持支承式で印刷プレートの交換が行われている間にインキ装置を静止させる際に、印刷インキがインキ装置のローラ上で乾燥するおそれがある、という問題が生じる。このことは、印刷条件を変化させ、かつ、印刷プレートの交換が行われた後に通常損紙印刷が行われるため、不利である。さらに、特許文献2に記載されている方法においては、交換すべき印刷プレートも対応のゴム胴のゴムブランケットも洗浄することができない。これによって、片持支承式で印刷プレートの交換を行うことが困難になり、その結果、印刷される損紙の量が増加することとなる。
以上のような事情に鑑みて、本発明の課題は、印刷機を運転するための新規な方法を提供することである。 In view of the circumstances as described above, an object of the present invention is to provide a novel method for operating a printing press.
この課題は、本発明の第1の態様によると、請求項1に係る印刷機を運転するための方法によって解決される。この第1の態様によると、印刷プレートの交換が行われている1つのまたは各印刷装置では、インキ装置および場合によっては湿し装置が、主駆動部によって引き続き駆動されるか、または、各印刷装置の版胴に対応させて設けられている個別駆動部もしくは直接駆動部によって駆動されるようになる。 According to a first aspect of the invention, this problem is solved by a method for operating a printing press according to claim 1. According to this first aspect, in one or each printing device in which the printing plate has been replaced, the inking device and possibly the dampening device are either continuously driven by the main drive or each printing device It is driven by an individual drive unit or a direct drive unit provided corresponding to the plate cylinder of the apparatus.
本発明の第2の態様によると、上記課題は、請求項10に係る印刷機を運転するための方法によって解決される。この第2の態様によると、連続印刷運転されている印刷装置において続いて印刷プレートの交換が行われることになっている場合、インキ装置のインキ着けローラを版胴から離間させ、その際、版胴上に配置されている印刷版を洗浄するために、かつ、版胴と協働する前記ゴム胴上に配置されているゴムブランケットを洗浄するために、印刷装置の版胴およびゴム胴が、所定時間の間または胴が所定の回数分回転する間、連続印刷位置に留まる。 According to a second aspect of the present invention, the above problem is solved by a method for operating a printing press according to claim 10. According to the second aspect, in the case where the printing plate is to be replaced subsequently in the printing apparatus that is continuously printing, the inking roller of the inking apparatus is separated from the plate cylinder, In order to clean the printing plate disposed on the cylinder and to clean the rubber blanket disposed on the rubber cylinder cooperating with the plate cylinder, the printing cylinder and the rubber cylinder of the printing apparatus are It stays in the continuous printing position for a predetermined time or while the cylinder rotates a predetermined number of times.
上記の2つの態様は、単独でまたは組み合わせた上で印刷機において適用され得る。 The above two aspects can be applied in a printing press alone or in combination.
本発明のさらなる構成は、従属請求項および以下の説明から明らかになる。本発明の実施例を以下に詳細に説明するが、本発明はそれに限定されない。 Further configurations of the invention emerge from the dependent claims and the following description. Examples of the present invention will be described in detail below, but the present invention is not limited thereto.
本発明は、印刷機を運転するための方法、すなわち、枚葉紙印刷機の他の印刷装置が連続印刷運転されている間に枚葉紙印刷機の少なくとも1つの印刷装置において片持支承式で印刷プレートの交換を行うための方法に関する。 The present invention is a method for operating a printing press, i.e., cantilevered in at least one printing device of a sheet-fed printing press while the other printing devices of the sheet-fed printing press are in continuous printing operation. Relates to a method for replacing a printing plate.
枚葉紙印刷機は複数の印刷装置を備える。これら印刷装置のそれぞれにおいて、印刷枚葉紙に部分画線部が塗布される。印刷装置はそれぞれ、圧胴と、圧胴に対して回転するゴム胴と、ゴム胴に対して回転する版胴と、を有する。この場合、ゴム胴上にはゴムブランケットが配置されており、版胴上には印刷版が配置されている。さらに、印刷装置はそれぞれ、インキ装置と、好適な実施形態においてはさらに湿し装置と、を有する。インキ装置によって、版胴上に配置されている印刷版に印刷インキが塗布される。湿し装置によって、版胴上に配置されている印刷版に湿し剤(Feuchtmittel)が塗布される。 A sheet-fed printing press includes a plurality of printing devices. In each of these printing apparatuses, a partial image portion is applied to a printed sheet. Each printing apparatus includes an impression cylinder, a rubber cylinder that rotates relative to the impression cylinder, and a plate cylinder that rotates relative to the rubber cylinder. In this case, a rubber blanket is disposed on the rubber cylinder, and a printing plate is disposed on the plate cylinder. Furthermore, each printing device has an inking device and, in a preferred embodiment, a dampening device. Printing ink is applied to the printing plate disposed on the plate cylinder by the inking device. A dampening agent (Feuchtmittel) is applied to the printing plate arranged on the plate cylinder by the dampening device.
印刷インキは、版胴からゴム胴に転移され、ゴム胴から印刷枚葉紙に転移される。この印刷枚葉紙は、ゴム胴と版胴との間に形成されたスリットを通過して搬送される。印刷すべき印刷枚葉紙は、いわゆる渡し胴によって印刷装置間を移動させられる。 The printing ink is transferred from the plate cylinder to the rubber cylinder and from the rubber cylinder to the printing sheet. The printed sheet is conveyed through a slit formed between the rubber cylinder and the plate cylinder. A printing sheet to be printed is moved between printing apparatuses by a so-called transfer cylinder.
この種の印刷機においては、いわゆる連続印刷中には渡し胴が枚葉紙印刷機の主駆動部によって駆動され、また、印刷装置の領域では、圧胴と、ゴム胴と、インキ装置と、湿し装置とが、枚葉紙印刷機の主駆動部によって駆動される。以下の記載においては、印刷装置の版胴またはプレート胴に個別駆動部または直接駆動部が対応させて設けられており、これらの個別駆動または直接駆動部によって、版胴は、連続印刷中には主駆動部から連結解除されているがこの主駆動部と同期するような状態で駆動される、ということを前提とする。 In this type of printing machine, during so-called continuous printing, the transfer cylinder is driven by the main drive unit of the sheet-fed printing machine, and in the area of the printing apparatus, an impression cylinder, a rubber cylinder, an inking device, The dampening device is driven by the main drive of the sheet printing machine. In the following description, an individual drive unit or a direct drive unit is provided corresponding to a plate cylinder or a plate cylinder of a printing apparatus, and the plate cylinder is provided during continuous printing by these individual drive unit or direct drive unit. It is assumed that the main drive unit is disconnected but is driven in a state of being synchronized with the main drive unit.
このように、他の印刷装置を連続印刷運転している間に印刷機の印刷装置において片持支承式で印刷プレートの交換を行うことになっている場合には、第1のステップにおいて、まだ連続印刷運転されているがその後片持支承式で印刷プレートの交換が行われることになっている印刷装置において、インキ装置のインキ着けローラは各印刷装置の版胴から離間させるが、湿し装置の湿し着けローラはさしあたって版胴に接触させたままにする。版胴およびゴム胴は当接位置に留まる。インキ着けローラを版胴から離間させた後、所定の第1の時間の間または印刷機もしくは胴が所定の第1の回数分回転する間、湿し着けローラも版胴から離間させるが、版胴およびゴム胴は引き続き当接位置に留まる。これに続いて、本発明による方法のさらなるステップにおいて、湿し着けローラを版胴から離間させた後、所定の第2の時間の間または印刷機もしくは胴が所定の第2の回数分回転する間、版胴およびゴム胴を離接位置に移動させる。 As described above, when the printing plate is to be replaced by the cantilever support type in the printing apparatus of the printing press while the other printing apparatus is continuously printing, the first step is not yet performed. In a printing apparatus that is operated continuously but is then cantilevered and the printing plate is to be replaced, the inking roller of the inking device is separated from the plate cylinder of each printing device. For the time being, the dampening roller is kept in contact with the plate cylinder. The plate cylinder and the rubber cylinder remain in the contact position. After the ink form roller is separated from the plate cylinder, the dampening roller is also separated from the plate cylinder for a predetermined first time or while the printing press or cylinder is rotated a predetermined first number of times. The cylinder and the rubber cylinder remain in the contact position. Following this, in a further step of the method according to the invention, after separating the wetting roller from the plate cylinder, the printing press or cylinder rotates for a predetermined second number of times or for a predetermined second number of times. Meanwhile, the plate cylinder and the rubber cylinder are moved to the separation position.
所定の第1および第2の時間の間または胴が所定の第1および第2の回数分回転する間、片持支承式で印刷プレートの交換が行われることになっている印刷装置の版胴およびゴム胴が当接位置に留まることになっているが、その間に、ゴム胴上に装着されたゴムブランケットと、版胴上に装着された印刷プレートとを、印刷プレートおよびゴム胴上に存在する印刷インキを印刷枚葉紙に転写して、いわゆる損紙印刷を行っている間に洗浄することができる。この場合、印刷プレートの交換が行われず、よって引き続き連続印刷運転されることになっている印刷装置の領域において、版胴およびゴム胴が一時的に離接位置におかれ、それにより、損紙印刷が行われている間または印刷プレートの交換が行われている印刷装置が洗浄されている間に、これらの印刷装置において印刷インキおよび湿し剤を節約することが好ましい。 A plate cylinder of a printing apparatus in which the printing plate is to be exchanged in a cantilevered manner during a predetermined first and second time or while the cylinder rotates for a predetermined first and second number of times. And the rubber cylinder is supposed to remain in the contact position, and in the meantime, the rubber blanket mounted on the rubber cylinder and the printing plate mounted on the plate cylinder exist on the printing plate and the rubber cylinder. The printing ink to be transferred can be transferred to a printing sheet and washed while performing so-called broken paper printing. In this case, the plate cylinder and the rubber cylinder are temporarily placed in the contact and disengagement position in the area of the printing apparatus where the printing plate is not exchanged and is therefore continuously operated for continuous printing. It is preferred to save printing ink and dampening agent in these printing devices while printing is taking place or while the printing device being replaced is being cleaned.
印刷プレートの交換が行われることになっている印刷装置の版胴およびゴム胴を離接位置に移動させた後、本発明による方法のさらなるステップでは、この印刷装置において片持支承式で印刷プレートの交換が行われる。印刷プレートの交換が行われることになっている印刷装置の版胴およびゴム胴を離接位置に移動させるのとほぼ同時に、引き続き連続印刷運転されることになっている印刷装置の版胴およびゴム胴であって、離接位置に既に移動されている版胴およびゴム胴を、再び当接位置に移動させる。続いて、連続印刷の間、印刷プレートの交換が行われることになっている印刷装置において、片持支承式で印刷プレートの交換が行われる。その際、印刷装置のインキ装置および湿し装置は、引き続き主駆動部によって駆動されるか、または、対応の版胴の個別駆動部によって駆動される。 After moving the printing cylinder and the rubber cylinder of the printing device to be replaced, the printing plate is further mounted in a cantilevered manner in this printing device in a further step of the method according to the invention. Is exchanged. The plate cylinder and rubber of the printing apparatus that are to be continuously operated at substantially the same time as the plate cylinder and rubber cylinder of the printing apparatus to be replaced are moved to the separating position. The plate cylinder and the rubber cylinder, which have already been moved to the separation position, are moved again to the contact position. Subsequently, in a printing apparatus in which the printing plate is to be replaced during continuous printing, the printing plate is replaced in a cantilevered manner. In that case, the inking device and the dampening device of the printing device are either continuously driven by the main drive unit or driven by the individual drive unit of the corresponding plate cylinder.
印刷プレートの交換を行っている間、印刷プレートの交換が行われることになっている印刷装置のインキ装置および湿し装置が主駆動部によって駆動される場合には、インキ装置に追加の印刷インキが供給されて印刷インキがインキ装置内で滞留することがないように、インキ装置を印刷インキつぼから離すことが好ましい。このために、すべてのインキゾーン調整部材(Farbzonenstellelemente)が閉じられるか、または、インキ装置のインキ移しローラ(Heberwalze)もしくはフィルムローラ(Filmwalze)が停止させられる。この場合、各印刷装置のインキ装置および湿し装置は、枚葉紙印刷機の主駆動部に連結されたままである。 While the printing plate is being replaced, if the inking device and dampening device of the printing device that is to be replaced is driven by the main drive, additional printing ink is added to the inking device. Is preferably separated from the printing ink fountain so that printing ink does not stay in the inking device. For this purpose, all the ink zone adjusting elements (Farbzonenstellelemente) are closed, or the ink transfer roller (Heberwalze) or film roller (Filmwalze) of the inking device is stopped. In this case, the inking device and the dampening device of each printing device remain connected to the main drive of the sheet-fed printing machine.
片持支承式で印刷プレートの交換が行われている間に、印刷プレートの交換が行われることになっている印刷装置のインキ装置および湿し装置が、対応の印刷装置のプレート胴の個別駆動部または直接駆動部によって駆動される場合には、インキ装置および湿し装置は、主駆動部から連結解除されて版胴または版胴の個別駆動部に連結される。すると、この場合、インキ装置および湿し装置は、主駆動部によって設定された回転数よりも明らかに少ない回転数で駆動されるので、インキ装置が印刷インキつぼから離されていない状態であっても最適な連続印刷条件を維持し続けることができる。 While the printing plate is being replaced in a cantilevered manner, the printing device's inking device and dampening device are individually driven by the corresponding printing device's plate cylinder. When driven by a direct drive or a direct drive, the inking device and the dampening device are disconnected from the main drive and connected to the plate cylinder or the individual drive of the plate cylinder. Then, in this case, since the inking device and the dampening device are driven at a rotational speed that is clearly less than the rotational speed set by the main drive unit, the inking device is not separated from the printing ink fountain. Even the optimum continuous printing conditions can be maintained.
印刷プレートの交換が行われた後で、インキ装置のインキ着けローラおよび湿し装置の湿し着けローラを、新しい印刷プレートを配した版胴に接触させ、それにより、印刷プレートに対してプレインキング(Voreinfaerbung)を行うようにする。プレインキングの際、ゴム胴および版胴は引き続き離接位置に留まる。 After the printing plate is replaced, the inking roller of the inking device and the dampening roller of the dampening device are brought into contact with the plate cylinder on which the new printing plate is arranged, thereby preinking against the printing plate Do (Voreinfaerbung). During pre-inking, the rubber cylinder and the plate cylinder remain in the separation position.
このようにプレインキングを行った後、印刷装置の版胴およびゴム胴を当接位置に移動させ、それにより、これら版胴およびゴム胴が再び連続印刷モードになるようスイッチを入れる。このことは、第1の変更形態ではただちに行うことができる。 After pre-inking in this way, the plate cylinder and rubber cylinder of the printing apparatus are moved to the contact position, thereby switching on the plate cylinder and rubber cylinder again in the continuous printing mode. This can be done immediately in the first variant.
第2の変更形態によると、他の印刷装置に続いてすぐに片持支承式で印刷プレートの交換を行うことになっている場合にも、他の印刷装置に続いて印刷プレートの交換が行われることになっている印刷装置を、ゴム胴および版胴を洗浄することによって印刷プレートの交換を行うべくまず準備する。 According to the second modification, even when the printing plate is to be replaced in a cantilevered manner immediately after the other printing apparatus, the printing plate is replaced after the other printing apparatus. The printing device to be printed is first prepared to replace the printing plate by cleaning the rubber cylinder and the plate cylinder.
上述した本発明による方法は、他の印刷装置の連続印刷中に印刷機の複数の印刷装置において片持支承式で印刷プレートの交換を行うことになっている場合にも、もちろん行うことができる。 The method according to the invention described above can of course also be carried out when the printing plates are to be replaced in a cantilevered manner in a plurality of printing devices of the printing press during the continuous printing of other printing devices. .
本発明による方法によって、印刷損紙を最低限に抑えつつ、特に効率良く片持支承式で印刷プレートの交換を行うことができるようになる。
The method according to the invention makes it possible to exchange printing plates in a particularly efficient cantilevered manner while minimizing printing waste.
