Can also be the stacked use of a plurality of flexible porous plates, annulus 1a, 1b do not draw in Fig. 2, inboard flexible porous plate 3a is with harder stainless steel cloth or the metallic porous sheet of many micropores is arranged, the stainless soft polyester webs of flexible porous plate 3b use evaporation in the outside.Supply the printing ink that comes in order to spread from the inside of plate cylinder 4 this moment, and the perforate ratio that preferably makes flexible porous plate is the closer to the body paper outside, the mesh number of porous plate high more (mesh is thin).Fig. 2 is a cutaway view, shows inner press roll 7a behind the inner peripheral surface that touches flexible porous plate 3, follows plate cylinder to rotate and makes the outwards expansion and turn to just relative with cross-arm portion position in turn on its radial direction of flexible porous plate.
Cross-arm portion 2 has certain width on the rotation direction of plate cylinder 4, one side is fixed the top of flexible porous plate 3 with fixture 15 at the rear of this rotation direction.Though the top of flexible porous plate 3 can directly be fixed in the cross-arm portion 2, also can for example fix indirectly with hinge etc.In addition, in Fig. 2, though the top of flexible porous plate 3 is positioned at the downside of cross-arm portion 2, this top also can be fixed on the surface of cross-arm portion 2 or with limit portion and become one continuously.But also can be fixed on cross-arm portion 2 on the periphery of annulus 1 near.Flexible porous plate 3 is reeled along the periphery of annulus 1a, the 1b of matrix, and its terminal flexibly is fixed on the advance side of cross-arm portion 2 rotation directions.As shown in Figure 2, when flexible porous plate 3 was made of multilayer, the rear end part of the flexible porous only rear end part of the flexible porous plate 3b of outermost layer that contacts with body paper of handle flexibly was fixed on the pawl 2a of cross-arm portion 2 by spring members 6.
In Fig. 2, in order to prevent that printing ink from leaking from the terminal of flexible porous plate 3a, 3b, make the outside different with the length of flexible porous plate 3a, the 3b of inboard, and the terminal of the flexible porous plate 3b in the outside is entered under the cross-arm portion 2, make the part of flexible porous plate 3b and the equitant overlay region C of a part of cross-arm portion 2 and be provided with one.
Among Fig. 3, be provided with the ink-feeding device of the supply printing ink in plate cylinder 4.As the inner peripheral surface (being the inner peripheral surface of flexible porous net 3) at plate cylinder 4 rotates by means of the driving of not shown drive unit with the rotation of plate cylinder 4 from the inner press roll 7a of the inside device for exerting, and closing the inner peripheral surface that leaves plate cylinder 4 on the non-image area of cross-arm portion 2, to avoid this part, be provided with doctor roll 7b near inner press roll 7a, it is controlled the ink film thickness on inner press roll 7a surface, and moves with inner press roll 7a one.
Arranged outside counter-pressure cylinder 8 at plate cylinder 4.Counter-pressure cylinder 8 has substantially the external diameter identical with plate cylinder 4, and is the center with an axle 8a parallel with the gyroaxis of plate cylinder 4, and unshowned in the drawings drive unit effect is rotated down or rotated synchronously with plate cylinder 4.On the position of the counter-pressure cylinder 8 corresponding, recess 8b is set with the cross-arm portion 2 of plate cylinder 4.Like this, it just rotates with plate cylinder 4 in the opposite direction synchronously, by paper feed roller the printing P among the 9 minim gap S that deliver between it and the plate cylinder 4 with inner press roll 7a clamping, print on printing and from the left side of Fig. 3 (a), sending to the right by the printing ink transfer printing of body paper.
At this moment, the rotational synchronization of inner press roll 7a and plate cylinder 4, when the printing beginning, make flexible porous plate 3 expansions of the place ahead part of plate cylinder 4 rotation directions, so in the minim gap S shown in Fig. 3 (b), by inner press roll 7a printing P is clipped between plate cylinder 4 and the counter-pressure cylinder 8, printing ink is transferred to paper P goes up and print.
During printing, though can clamp and force the mechanism that sends to the front end of paper P with being located at counter-pressure cylinder 8 lip-deep pawls, but when use handle as shown in Figure 3 just was clipped in the mechanism of printing between plate cylinder 4 and the counter-pressure cylinder 8 with paper P, counter-pressure cylinder was also passable with plate cylinder 4 different big less radiuses.
Fig. 4 represents to remove the state of flexible porous plate 3, on the periphery of doing with annulus 1a, the 1b of the contact-making surface of flexible porous plate 3 projection 11 is set, with this as reducing fricting resistance device.Each projection 11 is a hemispherical, on the periphery of the annulus 1 that whole and flexible porous plate 3 contacts, arrange many projections regularly, as long as it is highly consistent, frictional resistance to the flexible porous plate 3 that contacted is little, can not injure flexible porous plate 3, the shape of projection be Any shape can, but the shape of sphere or roller shape curved surface is arranged preferably, also passable in the rotating structure of the circumferencial direction of annulus 1, its size can be selected as required with density.
Fig. 5 is also the same with Fig. 4 to be to remove the state diagram afterwards of flexible porous plate 3, one or more rib 12 along the circumferential direction is set as the device that reduces frictional resistance on the periphery of the annulus 1 that contacts with flexible porous plate 3.Rib 12 can also play the printing ink that prevents in the plate cylinder 4 from the effect of flexible porous plate 3 with the boundary leakage of annulus 1.The width of rib 12 with can suitably select at interval, and when many ribs 12 were arranged, it was highly preferably consistent, many grooves is set replaces rib 12 also can reduce frictional resistance.In addition, can also on the periphery of annulus 1, paste lubricious material such as teflin tape as slidingsurface.And then, can also carry out smooth treatment such as polytetrafluoroethylene (PTFE) processing to the periphery of annulus 1 itself, also can carry out mirror process.
These are reduced on the edge inner surface that fricting resistance devices are located at the flexible porous plate 3 that contacts with the periphery of annulus 1 also be fine.
Now, flexible porous plate 3b and the cross-arm portion 2 equitant zone C among research Fig. 2.In zone C, produce friction because of stretching of spring members 6 between flexible porous plate 3b and the cross-arm portion 2.In order to reduce this friction, can above-mentioned projection 11 grades be set on the contact-making surface of cross-arm portion 2 and flexible porous plate 3b and reduce fricting resistance device.In this case, at least one side in flexible porous plate 3b or cross-arm portion 2 is provided with the reduction fricting resistance device.
During printing, porous body paper after the plate-making is wrapped on the outer peripheral face of plate cylinder 4, when plate cylinder 4 rotates, inner press roll 7a is along with the rotation of plate cylinder 4, the inner peripheral surface of the flexible porous plate 3 in driving lower edge of unshowned drive unit rotates in the drawings, perhaps does to involve rotation along the inner circumferential surface and the cylinder 4 of plate cylinder 4.The flexible porous plate 3 of plate cylinder 4 is along with the rotation of plate cylinder 4 is pushed by inner press roll 7a and outwards expansion successively from plate cylinder 4 rotation direction front part.
Counter-pressure cylinder 8 rotates with plate cylinder 4 synchronous backwards, it by paper feed roller the printing P among the 9 minim gap S that deliver between it and the plate cylinder 4 with inner press roll 7a clamping, to printing, and the left side from Fig. 3 (a) is sent to the right and is printed the printing ink continuously transfer printing by body paper.
At this, can reduce the reduction fricting resistance device of frictional resistance between the two owing on the contact-making surface of matrix (annulus 1 and cross-arm portion 2) and flexible porous plate 3, be provided with, with inner press roll 7a flexible porous plate 3 is extruded in the time of just successfully realizing the printing beginning.
And, with the rotational synchronization of plate cylinder 4 make inner press roll 7a leave the inner peripheral surface of plate cylinder 4, to avoid the non-image area of closing cross-arm portion 2.In a single day inner press roll 7a leaves the inner peripheral surface of plate cylinder 4, and flexible porous plate 3 just frees from the clamping of inner press roll 7a and counter-pressure cylinder 8.By means of the elastic force of the spring members 6 that is fixed on flexible porous plate 3 rear end parts the flexible porous plate 3 of expansion is pulled back.Now be described in more detail with regard to the frictional resistance that is produced between matrix in the above-mentioned action (ring-shaped article 1a, 1b and cross-arm portion 2) and the flexible porous plate 3.At first, inner press roll 7a contact is on the inner peripheral surface of plate cylinder 4 and with it during to external pressure, and spring members 6 elongations are so just produce frictional resistance between matrix and flexible porous plate 3.
Thereafter, the elongation of spring members 6 remains unchanged during plate cylinder 4 rotates, and the still expansion and not moving to circumferencial direction of flexible porous plate 3 is so the friction that does not produce circumferencial direction between matrix and flexible porous plate 3.
Inner press roll 7a has just eliminated the outside expansion that makes flexible porous plate 3 because of inner press roll 7a face from the moment that plate cylinder 4 inner peripheral surfaces are thrown off, and does not produce frictional resistance between annulus 1a, 1b and flexible porous plate 3.Here it is in the present embodiment, makes inner press roll 7a leave the reason of the inner peripheral surface of plate cylinder 4 near the terminal of flexible porous plate 3a.
Yet, when for example inner press roll 7a is positioned on the position shown in Figure 2, break down or in occasions such as body paper image area ends of a period at printing machine, if this device of control makes this inner press roll 7a leave the inner peripheral surface of plate cylinder 4, then locate at the rear side (left side of inner press roll 7a in Fig. 2) of plate cylinder 4 rotation directions, flexible porous plate returns under the pulling force effect of spring members 6, will produce frictional resistance between the periphery of flexible porous plate and ring-shaped article.
Because at overlay region C, the inner surface side of cross-arm portion 2 contact with flexible porous plate 3, no matter inner press roll 7a leaves the inner peripheral surface of plate cylinder 4 on where, understands generation frictional resistance in the moment of its disengaging on this contact portion.
As described above, when this device contacts with the inner peripheral surface of plate cylinder 4 or breaks away from inner press roll 7a, all can produce frictional resistance in the flexible porous plate 3 and the contact portion between the matrix towards plate cylinder rotation direction rear one side of inner press roll 7a position.
Above-mentioned projection 11 that minimizing contact area between the two uses etc. is set in order to reduce the frictional resistance between flexible porous plate 3 and annulus 1 or the cross-arm portion 2 and forms the gap between the two, because this gap is arranged, printing ink just enters easily.Can be as shown in Figure 6, setting and projection 11 or rib 12 are with high stop part 13, so that the unlikely outside that drains to plate cylinder 4 of printing ink continuously.Under situation about being arranged on the annulus 1, then on the relevant attached near part in center of the gyroaxis of plate cylinder 4, be provided with continuously along its circumferencial direction.
In flexible porous plate 3b and cross-arm portion 2 in the plate cylinder of the overlapping structure shown in Figure 2 of zone C, for preventing to go out printing ink from plate cylinder 4 internal leakages, and as shown in Figure 7, with the stop part 13 that is parallel to rotating shaft and joins with the ora terminalis part 2a inboard of cross-arm portion 2 is set above the rearward end of the overlapping flexible porous plate 3 of cross-arm portion 2 continuously.
In addition, as shown in Fig. 8 (a) and (b),, the projection 14 that is located on annulus 1 periphery is become to prevent that printing ink is from plate cylinder 4 interior shapes to external leakage in order to reduce frictional resistance.In this case, preferably relevant and can prevent the shape that stops the dam that printing ink moves outside the side direction of center with the gyroaxis of plate cylinder 4.
Below understand embodiments of the invention in detail, but scope of the present invention is not limited thereto, concerning those skilled in the art, obviously can realizes various application and modification.
