Description
Technical field
The present invention relates to a kind of have a plurality of inking mechanisms (Farbwerk)-the comprise printing equipment of plate cylinder, blanket cylinder and printing cylinder and the printing machine of a turning device (Wende-einrichtung), wherein at least one printing cylinder is arranged on after described at least one turning device as the printing cylinder (Nachwende-Druckzylinder) that overturns again, and is supporting a cylinder-packing (Aufzug) or a structure coloured surface (Struktur-chromoberflaeche).
Background technology
DE 201 07 183 U1 disclose the printing machine of the above-mentioned type.This printing machine has one and has a printing machine that is arranged on the turning device printing cylinder that overturns again afterwards.This printing cylinder that overturns is again supporting a cylinder-packing that adhesively is arranged on the lip-deep coating of being made by molybdenum of supporting material by a kind of flexible supporting material and.A sealant of being made by polysiloxanes family (Polyorganosiloxane) adhesively is arranged on the surface of this coating.This cylinder-packing has a surface section of being made by the taper that has cavetto section circular arch towards printing material.Coating also can be made by tungsten carbide/cobalt in another embodiment.Employing be provided with a kind of like this cylinder-packing overturn again printing cylinder in order that front seal and reverse side India and China prevent after upset printing ink or paint from first emaciated face of paper from descending.
Printing cylinder with structure coloured surface also can be used as the printing cylinder that overturns again.
In order to clean the printing cylinder of upset again with a kind of like this surface, what adopt up to now is the method for describing in DE 40 13 465 A1.Printing cylinder is sent to the device location of rubber printing cylinder when clean operation, therefore utilizes disclosed blanket cleaning device both can clean blanket, also can clean printing cylinder.In this method on the one hand frame for movement must and to be used for the printing feeding of printing material thickness balance suitable, clean blanket cylinder on the other hand and printing cylinder is time-consuming, and partly also must manual cleaning again.
DE 199 31 305 A1 disclose a kind of printing equipment that is used for a rotary press, especially for the wiper mechanism of a printing cylinder, wherein, with a cylinder that is coated with brush as the purging system setting.Disclosed wiper mechanism is used to clean the printing cylinder of no cylinder-packing or structure coloured surface in the document.
In DE 203 08 645 U1, show and described a kind of printing machine, wherein on blanket cylinder and printing cylinder, be provided with the wiper mechanism that separates.Yet illustrated printing machine does not have turning device and the printing cylinder that overturns again in this piece document.
Summary of the invention
Task of the present invention is to provide a kind of printing cylinder that overturns again to the guiding printing material to carry out the printing machine that protectiveness is cleaned.Described in addition task also is, need not carry out craft when printing cylinder is overturn in cleaning again and clean, and scavenging period is the shortest.
The invention provides a kind of printing machine with a plurality of printing equipments and a turning device, described printing equipment comprises inking mechanism, forme blanket cylinder and printing cylinder, wherein, be arranged on the back of described at least one turning device as at least one printing cylinder of the printing cylinder that overturns again, and supporting a cylinder-packing or a structure coloured surface, it is characterized in that described at least one printing cylinder that overturns again has the printing cylinder of a upset again wiper mechanism that separates with the blanket wiper mechanism of affiliated blanket cylinder.
This task is finished by following measure according to the present invention: described at least one printing cylinder that overturns again has the printing cylinder of a upset again wiper mechanism that separates with the blanket wiper mechanism of affiliated blanket cylinder.
Advantage according to the solution of the present invention is can effectively clean in the shortest scavenging period, and need not manual cleaning again.In addition, for blanket cylinder and the printing cylinder that overturns again, can use different cleansing mediums.In addition can be advantageously upgrade the sealing that the sealant by applying liquid carries out by the printing cylinder wiper mechanism that overturns again that separates.
The present invention gives favourable improvement project.Particularly advantageous is as the printing cylinder of the upset again wiper mechanism that separates with a brush wiper mechanism.This wiper mechanism special protection ground cleans the printing cylinder that overturns again, and on the structure of brush and can be suitable with the lip-deep specific (special) requirements of the printing cylinder that overturns again on the cleaning procedure structure.The structure of the section of the printing cylinder that overturns again of protecting especially of brush is that the free end of the mane of brush splits into a plurality of mane points that reduced mane point thickness that have at least in part.In addition advantageously, affiliated blanket roller is provided with the blanket wiper mechanism of cloth wiper mechanism form, because this cleaning way is fit to blanket cylinder.Another favourable improvement project is that the printing cylinder under the situation that does not have cylinder-packing or structure coloured surface also is provided with separative printing cylinder wiper mechanism.Such wiper mechanism can be brush wiper mechanism or cloth wiper mechanism preferably.Preferably by can reducing scavenging period further for the wiper mechanism that separation also is set in the inking mechanism of blanket cylinder or printing cylinder of attaching troops to a unit.In addition proof advantageously, printing machine be provided with one both controlled the printing cylinder wiper mechanism, again overturn the printing cylinder wiper mechanism, also control the wiper mechanism controller of blanket cylinder wiper mechanism and inking mechanism wiper mechanism.So just can carry out can be correspondingly and the suitable unified cleaning procedure of dirty degree.So just can realize reducing further scavenging period.Advantageously control above-mentioned wiper mechanism-be that they move simultaneously if so, then reduce scavenging period especially bigly.A particularly advantageous form of implementation according to printing machine of the present invention is that the wiper mechanism controller is also additionally controlled the feed mechanism and the power supply of the washing agent of wiper mechanism.So just can realize the automatic washing of whole printing machine.
Description of drawings
Unique Fig. 1 represents one embodiment of the present of invention.Below embodiments of the invention are described in detail.
Fig. 1: according to the diagrammatic side views of printing machine of the present invention.
The specific embodiment
Have eight printing equipments 1 and two ink devices 2 at the paper offset press shown in Fig. 1.Be provided with a turning device 3 in a back of four printing equipments 1, the paper that this turning device upset is carried through four printing equipments 1 from feeder 4 is so that can print another side.
Each printing equipment 1 has a unshowned inking mechanism and a unshowned edition-0 moistening mechanism.Also have a printing plate cylinder 5 and a blanket cylinder 6 to belong to each printing equipment 1 in addition.Front at turning device 3 is provided with printing cylinder 7 in each printing equipment 1.Printing cylinder 7 can have a smooth coloured surface.Yet they do not have cylinder-packing not have the structure coloured surface yet.The printing cylinder that belongs to each printing equipment 1 in turning device 3 back has a cylinder-packing or a structure coloured surface as the so-called printing cylinder 8 that overturns again.
