The structure of the outer peripheral face 1a of the existing cylinder 1 of following simple declaration.Figure 13 is the cut-away view of platemaking equipment in the past.Figure 14 is the expansion Local map of the outer peripheral face 1a of cylinder 1 shown in Figure 13.
In Figure 13, chain-dotted line L

3Expression is formed on the adsorption tank on the outer peripheral face 1a of cylinder 1.In Figure 13, X1, X2(are diagram, total length for cylinder 1) corresponding to the length direction of cylinder 11, Y1, Y2 are axial corresponding to cylinder 11, wherein, zone X1(Y1+Y2) be the zone of the galley 2 of coiling minimum dimension, regional X2(Y1+Y2) be the reel zone of maximum sized galley 2 and regional X2(Y1+Y2) only show the part.
As shown in figure 13, on the cylinder outer peripheral face 1a of existing platemaking equipment, at L

2, L
3Position and the L of intersection
3Figure in the bottom be formed with a plurality of adsorption holes 23.At regional X1(Y1+Y2) and regional X2(Y1+Y2) (wherein, except regional X1(Y1+Y2)) all be formed with a plurality of adsorption holes 23.
The cylinder outer peripheral face 11a of this platemaking equipment has, and the feature that the cylinder outer peripheral face 1a of existing platemaking equipment does not have is mainly following (1) and (2).
(1) the regional X1(Y1+Y2 of the galley 2 of coiling minimum dimension) and the regional X2(Y1+Y2 of the maximum sized galley 2 of reeling) (wherein, except regional X1(Y1+Y2)) in adsorption tank L
1, L
2, L
3Density all become greatly, namely increased the density of adsorption hole, and regional X1(Y1+Y2) in the density of adsorption hole 23 increase than regional X2(Y1+Y2) (wherein, except regional X1(Y1+Y2)) and in the density of adsorption hole large.
Thus, although the power output of air blast 41 diminishes, but owing to increased the density of adsorption hole, in the situation of the galley 2 of using the size less than maximum size, although air can never be printed the adsorption hole 23a(leak holes that version 2 covers) enter in the cylinder 11, but the density of leak holes is less than the adsorption hole 23 that is printed version 2 coverings, the density of 23a, so suppress the amount of the air that enters few, and the inner and outer air pressure that can guarantee cylinder 11 is poor large, guarantees galley 2 is adsorbed in the intensity of outer peripheral face 11a.
(2) at the regional X2(Y1+Y2 of maximum sized galley 2 that reels) (wherein, except regional X1(Y1+Y2)), with the regional X1(Y1+Y2 of the galley 2 of coiling minimum dimension) compare, be provided with the little adsorption hole 23a of diameter.That is, if at regional X1(Y1+Y2) in adsorption hole 23 with the diameter that equated in the past is set, then at regional X2(Y1+Y2) (wherein, except regional X1(Y1+Y2)) in the little adsorption hole 23a of diameter than in the past is set.
Thus, in the situation of using the galley 2 of little size than full-size, although air never is printed the adsorption hole 23a(leak holes that version 2 covers) enter in the cylinder 11, because the diameter of leak holes is less than in the past, so can suppress the air capacity that enters few.Therefore, even use power output than in the past little air blast 41, also can guarantee greatly with the inner and outer air pressure of cylinder 11 is poor, guarantee galley 2 is adsorbed in the intensity of outer peripheral face 11a.
In this galley adsorbing mechanism, owing to have simultaneously the feature of above-mentioned (1) and (2), even because used the galley 2 of the size less than full-size, although used power output than in the past little air blast 41, also can guarantee enough absorption affinities.As a result, in having used the cylinder outer surface sweep type platemaking equipment of this mechanism, when making cylinder 11 High Rotation Speed, galley 2 absorption are fixed on the outer peripheral face 11a of cylinder.
At this, Fig. 8 is arranged on regional X1(Y1+Y2 shown in Figure 2) in the structure example (top view and cutaway view) of adsorption hole 23.Fig. 9 is arranged on regional X2(Y1+Y2 shown in Figure 2) (wherein, except regional X1(Y1+Y2)) in adsorption hole 23a, namely form the structure example (top view and cutaway view) of the adsorption hole 23a of leak holes.In Fig. 8, the diameter of adsorption hole 23 and adsorption tank L
1, L
2, L
3Width about equally.In Fig. 9, the diameter of adsorption hole 23a is less than adsorption tank L
1, L
2, L
3Width (for example, be roughly adsorption tank L
1, L
2, L
3Half of width).
More than, the platemaking equipment of the galley adsorbing mechanism that has simultaneously above-mentioned (1) and (2) these 2 features has been described, even but only have wherein 1 feature, just can be than in the past stronger absorption affinity, obtain to reduce the effect of the danger that galley comes off.
In addition, in the above description, feature about above-mentioned (2), only put down in writing at regional X2(Y1+Y2) (wherein, except regional X1(Y1+Y2)) in diameter is set than regional X1(Y1+Y2) in the little adsorption hole 23a of diameter, show the structure example of these two kinds of adsorption holes 23,23a at Fig. 8 and Fig. 9, but the shape of adsorption hole 23,23a is not limited only to this example.
That is, in the example of Fig. 8 and Fig. 9, adsorption hole 23,23a are cylindric, also can form the stupefied post shapes such as four stupefied posts or six stupefied posts.But, the amount of the air that enters from adsorption hole 23 is mainly determined by the cross-sectional area of adsorption hole 23, thereby adsorption hole 23 formed stupefied column especially, the such columned adsorption hole 23 of Fig. 8 and Fig. 9,23a because only utilize bores etc. and just can form in cylinder outer peripheral face 11a boring, thereby can reduce cost.
But in the situation of utilizing the such adsorption hole 23a of brill Fig. 4, the diameter in hole is the smaller the better, and in addition, Kong Yueshen is better, needs elongated brill, thereby the damaged danger of brill becomes greatly.For fear of such danger, for example shown in Figure 10, for being arranged on regional X2(Y1+Y2) (wherein, except regional X1(Y1+Y2)) interior adsorption hole 23a, with the hole dimidiation, the diameter of the column part 23aA of outer side face 11a is large (for example, with adsorption tank L with the degree of depth of regulation
1, L
2, L
3Width about equally), (for example, be roughly adsorption tank L by the diameter of the column part 23aB of the inner peripheral surface opposite with outer peripheral face 11a one side is little
1, L
2, L
3Half of width).
Form Figure 10 such with the poor hole of ladder the time, as long as at first utilize large diameter brill to be bored into the degree of depth of regulation from outer peripheral face, then, the brill that utilizes minor diameter is bored into the inner peripheral surface position again from the lower surface in this hole.And, at this moment, compare with the adsorption hole 23a of Fig. 9, although the little part of diameter is short, the amount of the air that enters from adsorption hole 23 does not almost have difference.This is because the amount of the air that enters from adsorption hole 23 is only decided by minimum sectional area.
As mentioned above, according to present embodiment, even the attraction of air blast 41 is less than in the past, but because little than in the past of adsorption hole 23,23a, also can guarantee greatly with the inner and outer air pressure of cylinder 1 is poor, and guarantee that galley 2 is adsorbed in the intensity of the outer peripheral face 1a of cylinder.As a result, when making cylinder 1 High Rotation Speed, guarantee that galley 2 is attached to the outer peripheral face 11a of cylinder reliably.
