The invention provides a versatile offset or flexographic printing machine for guiding sheets that is simple to adjust and cost-effective to produce, as a result of the fact that, in the guiding position for the sheets, the feed claw is completely enclosed by the cylinder which is defined by the circumferential surface of the impression cylinder.
Description
Technical field
The present invention relates to a kind of sheet-fed press (sheet-processing printing press), this printing machine has at least one flexible cylinder or blanket cylinder, and at least one has the impression cylinder of at least one paper feeding clamper.
Technical background
Generally speaking, people have known four kinds of different printing processes.At first, known have a letterpress method, and the feature of this method is the inking part projection of forme, but not printing depression.Lithographic printing also is known, and wherein the inking of forme part and non-printing (in fact) are in one plane.Intaglio printing is common printing process, and especially for newspaper printing, wherein the inking of forme is partly caved in.At last, so-called screen painting or method for printing screen also are known, and wherein on the position of need printing, pigment is delivered on the need materials printed by the hole of the mesh-like of forme.
Except type printing, the letterpress method also comprises so-called flexible printing or aniline printing, and wherein forme is flexible.
At present, traditional offset printing drops in the lithographic category.By suitable processing, can make the part that will print become oil absorption, that is to say that when at last China ink, these branches of Printing Department draw (oiliness) printing ink, the part that need not to print is then scolded oiliness, that is to say it is to repel printing ink.
At sheet-fed press or open under the situation of page or leaf printing machine, each page or leaf is many Di to take out from pile, and is passed to one and the printing cylinder impression or the idler pulley that lean by conveying roller.In this process, the printing ink that is coated in advance on the printing cylinder can be transferred on the page or leaf.
The sheet-fed flexibility that can buy on the open market or the printing cylinder of offset machine have the groove that at least one extends vertically, promptly so-called printing forme mounting groove.Flexible printing forme is installed in printing forme and installs between two adjacent grooves of cylinder.
Open page or leaf in order to transmit, impression cylinder has a clamper usually, and this clamper is made up of a clamping limb and a gripper pad.Clamper also is arranged in the groove of impression cylinder.In transmission and clamping process, the side that faces toward gripper pad of opening page or leaf that needs to transmit is placed on the impression cylinder.Clamping limb is forced on the side that deviates from gripper pad of a page or leaf.When impression cylinder rotates, remain on clamper between gripper pad and the clamping limb by opening page or leaf, just can transmit a page or leaf.
In order to print as much as possible to an edge of opening page or leaf, and obtain higher alignment precision, traditional sheet-fed offset printing or flexible printing machine all will note allowing a page or leaf folding.For this reason, beyond the clamping limb that on the side that deviates from impression cylinder of opening page or leaf it is carried out clamping must the outline at impression cylinder.Yet, along with printing cylinder and impression cylinder mutually directly against, clamper also protrudes into the outline of printing cylinder inevitably.This is not a shortcoming for traditional flexibility and offset printing sheet-fed press, because as described in the quoted passage, printing cylinder or printing forme are installed cylinder and had the groove that is printing forme mounting groove form, and the clamper that protrudes on impression cylinder just in time can insert this groove.
Opposite with sheet-fed press is that web press is provided with the printing cylinder that does not have groove.Owing under the situation of web press, needn't clamp sheet-fed, thereby can omit the clamper on supporting or the impression cylinder.Owing to there is not the part of clamper to protrude from the outline of impression cylinder, thereby can installs at printing forme groove is not set on the cylinder.Under the situation of web press, replace aforesaid installation printing forme, can adopt a so-called sleeve with closed circular post shapes.Under this mode, for example can print continuously roll web.
Yet, known sheet-fed offset printing and flexible printing machine have such shortcoming: on the one hand, flexible printing forme must be installed on the cylinder at printing forme and regulate individually, on the other hand, the known offset printing and the impression cylinder of flexible sheet-fed press can not be used for other printing process, because on resting position, clamping limb convexedly stretches on the impression cylinder outline, and printing cylinder must be provided with unalterable groove.Yet for example in intaglio printing, such groove is acceptable, because printing cylinder is immersed in the printing ink in the case, but so just must " cleaning " unnecessary printing ink.
Summary of the invention
Therefore, the objective of the invention is to, a kind of general, that be convenient to regulate, cheap for manufacturing cost sheet-fed offset printing or flexible printing machine are provided.
According to the present invention, this purpose is to solve like this, that is, clamper is arranged in the cylinder that outer peripheral face limited by impression cylinder fully.
At this, should be understood as the outer peripheral face of impression cylinder roughly is the surface portion that leans with printing cylinder of impression cylinder.Optionally, impression cylinder can be provided with one and have the zone of minor radius slightly, speaks by the book, and the outer peripheral face of impression cylinder defines a cylinder with small radii in this zone.
Because clamper is arranged in the profile scope of impression cylinder, that is to say not protrude out on the groove, if desired, can omit the groove in the printing cylinder or claim the printing forme mounting groove.Therefore, as web press, can adopt a sleeve to replace flexible printing forme.Yet, it should be noted that the outer printing surface of sleeve can not all be used, between each page or leaf, must maintain a gap, so that cooperate clamping limb to transmit a page or leaf.So this sleeve also must be provided with a non-printing zone.Therefore, in the method for flexible printing, be necessary for the special manufacturing of sheet-fed printing and use sleeve at least.
This advantage that is used for the new clamper configuration of offset printing and flexible printing is, also this impression cylinder can be used for other printing process, for example intaglio printing.Therefore, for example can change a flexible cylinder or a blanket cylinder that is used for photogravure roller simply, needn't on the sheet-fed press structure, do other any variation.
Can be used for roll web and sheet-fed press according to impression cylinder of the present invention.In addition, if desired, can apace sheet-fed press be transformed into web press, vice versa.Preferably, clamper of the present invention is being used under the situation of web press, being used in the impression cylinder admits the groove of clamper to be installed sealing to improve the printing area on the roll web by one at least in part, and described device also can match with clamping limb.
On the lower position that clamper is arranged in radially, (that is to say at a fringe region of opening page or leaf) in clamping zone to have a spot of page or leaf bending.Yet, have found that unexpectedly, this bending can't have any influence to alignment precision.In addition, under this mode, a margin edge that can not be printed must have some expansions.
Because according to layout of the present invention, compare radially inside further by the paper feeding action that clamper carries out with so-called printing zone (just opening the zone that page or leaf is printed), when the structure printing machine, must consider that present printing zone has different rotating speeds with the paper feeding zone under unequal angular velocity.Therefore, be necessary for paper feeding and print drum (printing periphery) usually two independent driver (for example gear drive) are set.
Open page or leaf for clamping fast and reliably, advantageously, clamper is made of a clamping limb and a gripper pad, and wherein at least one clamping limb can move with respect to gripper pad.For example, also clamping limb can be arranged to and pivot around a pivot.When a page or leaf was positioned on the gripper pad, clamping limb was rocked on the gripper pad, will open page or leaf and be clamped between gripper pad and the clamping limb.When printing cylinder and impression cylinder with unequal angular velocity, when opposite turning to rotated, open page or leaf and between printing cylinder and impression cylinder, advance by clamper, be printed simultaneously.
Perhaps, be clear that,, clamping limb can be installed in a fixed manner, and gripper pad be arranged to removable the specific occasion.Optionally, gripper pad and clamping limb is to guarantee that it also is favourable clamping moving of a page or leaf.
To some occasion, advantageously, at least one printing cylinder is arranged in a top in page or leaf path.Under this mode, can touch printing cylinder at an easy rate, thereby make change printing forme or corresponding sleeve become easy.
It is desirable especially that such an embodiment is arranged, and wherein at least one flexible printing cylinder or blanket cylinder (optionally having ink feeder) can be replaced with the photogravure roller that has ink feeder.According to the application, printing machine is changed as required.Therefore, several flexible printing cylinders or corresponding blanket cylinder, or even photogravure roller also can be arranged one by one selectively, and have corresponding drying device.Photogravure roller and flexible printing cylinder can be combined in the hybrid printing machine of so-called sheet-fed as required.Combine intaglio printing and cheaply the hybrid printing machine of sheet-fed of the various advantages of flexibility or offset printing can on basis of the present invention, implement easily.
For specific requirement, advantageously, clamper or corresponding gripper pad are adjustable, and like this, clamping limb can be arranged in the radially inner side or the radial outside of outline according to the occasion location.Under this mode, what can guarantee is when a printing forme installation cylinder with groove or printing forme mounting groove is used as printing cylinder, clamper can be arranged to make the page or leaf in the clamping zone not bend or bending.This adopt unusual rigidity open page or leaf the time advantageous particularly.In the case, printing machine preferably is provided with at least one adjustable impression cylinder, gap between itself and the adjacent conveying roller can change in specific limited field at least, thereby the peripheral speed of paper feeding can be complementary with the peripheral speed of print drum periphery.
Description of drawings
The application's other advantage, feature and application possibility can be by becoming clear below in conjunction with accompanying drawing to the description of a preferred embodiment.In the accompanying drawing:
Fig. 1 shows one according to clamper configuration of the present invention; And
Fig. 2 shows another page or leaf of clamper and supplies with the position.
The specific embodiment
In Fig. 1, the outline of dotted line 1 expression impression cylinder.The outline of dotted line 2 expression printing cylinders.Give open page or leaf 3 be sandwiched in as shown in the figure on the position between gripper pad 4 and the clamping limb 5.Clamper that is to say that gripper pad 4 and clamping limb 5 are connected in impression cylinder.When printing cylinder 2 and impression cylinder 1 with identical peripheral speed when direction shown in the arrow moves, open page or leaf 3 and between printing cylinder and impression cylinder, pass through, be printed simultaneously.Can be clear that clamping limb is that be arranged to can be radially inside in the outline scope of impression cylinder 1.Under this mode, clearly visible from accompanying drawing, opening page or leaf must the slight curving or bending of edge region.Test shows many times, this slight bending of opening page or leaf can not cause the problem aspect any aligning location when flexible printing or offset printing.
As described in the text, be more favourable when gripper pad being made in the time of to regulate.As shown in Figure 2, on the paper feeding position of clamper, gripper pad is radially outwards moved.This position corresponds essentially to the position of the clamper in traditional sheet-fed press.Obviously, clamping limb in impression cylinder, convexedly stretch in groove above.On this position, open the fringe region minimum that can not print on the page or leaf.
Compare with position shown in Figure 1, the advantage of this position is that a page or leaf needn't be in its fringe region bending.Yet, have only when corresponding printing cylinder has a groove 6 (a for example printing forme mounting groove 6), just clamper so may be arranged.Like this, as long as regulate, just clamper can be set on the best position according to used printing cylinder.
By the present invention, can improve the flexibility of sheet-fed flexible printing machine and sheet-fed offset machine greatly.Therefore, for example all known printing processes can be combined in the printing machine as required.As mentioned above, in a particular embodiment, can arbitrarily change printing cylinder.Under this mode, can in modular mode each print steps be made one's options according to required printing process (no matter being intaglio printing, flexible printing or offset printing).
