Description
The present invention is mainly about printing machine, relates in particular to a kind of dumping processing solution is applied to modifying device on a kind of lithographic plate.
The design of the lithographic plate that uses on offset press makes the some (for example, will producing desired that part that obtains image) of lithographic plate can adsorb printing ink, and the remaining part of this galley is then made and can be prevented that printing ink is adsorbed onto on its surface.A kind of dumping processing solution (for example water promptly can add the additive as alcohol in the water, also can not add) appends on the flat board, so that the blank parts on this galley soaks, thereby prevents that ink adhesion from going to their surfaces.In order to access best printing effect, must accurately control the interpolation of dumping processing solution on lithographic plate.Because dumping processing solution is too much or deficiency all can make printing quality inferior.
United States Patent (USP) (patent No. is 3163037, and it has authorized Harol P.Dahlgren patent in February 2 nineteen sixty-five) discloses a kind of equipment of wet offset print galley.In this equipment, avoided direct contact the between lithographic plate and the dumping processing solution source.This equipment was applied on the lithographic plate of printing ink dumping processing solution equably, and don't with ink adhesion in edition-0 moistening mechanism.This equipment has used a kind of liquid medicine feed rolls, and it is one smooth that this roller has, the outer surface that the metal finished machined is crossed but also through chemical treatment, thus make this liquid feed rolls have the ability (being hydrophily) of adsorbed water.An inking roller of the liquid feed rolls of this possess hydrophilic property and this printing machine meshes rotationally, so that the dumping processing solution film on this liquid medicine feed rolls is scatter.The part of dumping processing solution film is adsorbed by the ink lay on the inking roller, and this liquid medicine film is transferred to lithographic plate gets on.Another part dumping processing solution film is also stayed on this liquid medicine feed rolls, in order to prevent ink adhesion, has so just prevented that printing ink back is sent in the edition-0 moistening mechanism.
Main purpose of the present invention is a kind of to being the improvement of the dampening device that discloses in 3168037 the United States Patent (USP) in the patent No..Machine of the present invention structurally with on the function has many improvement and advantage.These improve and advantage has been improved the damping operating procedure widely, thereby have also just improved the quality of printing.
Dampening device of the present invention has used a kind of liquid medicine feed rolls of possess hydrophilic property, this feed rolls is directly driven by a variable-speed motor, and this feed rolls also provides a kind of supporting for other roller in this device mobile, and its effect is exactly a kind of center of rotation.Used a kind of dancer rools in the most preferred embodiment of this device, this dancer rools is being driven by the liquid medicine feed rolls, rotate with big slightly a little speed, and this dancer rools and liquid medicine feed rolls also be among the continuous engagement, make relative slip or the fricting movement of generation between them.So, on the liquid medicine feed rolls of possess hydrophilic property, just keep the uniform moisture film or the water layer of the accurate control of one deck.
Dancer rools is bearing on the main supporting suspension bracket, this suspension bracket can rotate around the revolution axial line of hydrophily liquid medicine feed rolls, thereby make this dancer rools in an arc scope that is limited, move, and keep transmission simultaneously and keep roller and the engagement of the liquid medicine of possess hydrophilic property supply roller.
Placing the damping ink roller is to be used to make it to mesh selectively with the liquid medicine feed rolls and the lithographic plate plate cylinder of possess hydrophilic property.This mounting means is realized by means of this damping ink roller is installed on the damping ink roller suspension prejudicially.Damping ink roller suspension is hinged to again on the main supporting suspension bracket.The revolution axial line that is rotationally connected of damping ink roller suspension and the revolution axial line of damping ink roller have a spacing, this spacing make the oscillating motion of damping ink roller suspension produce the damping ink roller and the contact position of hydrophily liquid medicine feed rolls and the arcuate movement of the certain limitation between the non-contacting position.Adjustable limit stops piece is accurately being determined contacting between the liquid medicine feed rolls of damping ink roller and possess hydrophilic property.
By the power transmission that Pneumatic working cylinder, lever arm and toggle constituted, its operation at first makes the motion of damping ink roller suspension, make the damping ink roller contact engagement with hydrophilic liquid medicine supply roller is arranged, subsequently, this power transmission moves main supporting suspension bracket, the damping ink roller is contacted with the lithographic printing-plate cylinder, and this contact engagement is also accurately being controlled by an adjustable stop block.
Cross-over connection roller be installed in it is in and inking roller and damping ink roller between carry out the position of Continuous Contact, one deck printing ink can be applied on the damping ink roller continuously.The damping ink roller is by this cross-over connection roller and plate cylinder transmission, and its velocity of rotation speed more selected than the liquid medicine feed rolls of possess hydrophilic property is littler.
As determined by structural design, when printing machine did not carry out printing operation, the damping ink roller did not promptly contact with the liquid medicine feed rolls of possess hydrophilic property, does not contact with plate cylinder yet.The operation running of actuating unit is to make the damping ink roller contact engagement with the liquid medicine feed rolls of possess hydrophilic property at first, and the speed that relatively rotates between damping ink roller and the hydrophilic liquid medicine feed rolls makes the accurate one deck water controlled of warp or moisture film " roll extrusion " to the damping ink roller.One thinks surely: this water layer or moisture film on the liquid medicine feed rolls of possess hydrophilic property are dispersed, and a part of moisture film wherein is to be left on the liquid medicine feed rolls, in order to preventing printing ink absorption, thereby have prevented that printing ink from entering into the liquid medicine organization of supply and going.
The further action of power transmission makes the damping ink roller contact with plate cylinder, thereby makes that one deck be applied on the lithographic plate through the moisture film of accurately control.The water that is added on the lithographic plate is adsorbed by the blank parts on this forme, thereby makes it to obtain best printing effect.
The various motions of edition-0 moistening mechanism all are the moved in coaxial of the dumping processing solution feed rolls of fixing, possess hydrophilic property of unrolling.Make that like this adjusting of various rollers is very easy, but also make the adjusting of a roller can not have influence on the installation adjusting of other roller.Drive the liquid medicine feed rolls of turning round the possess hydrophilic property on the axial line fixing with a variable-speed motor, the gear installation has been omitted in this measure, is very general in the prior art and gear is installed.
For edition-0 moistening mechanism of the present invention, the important improvement of another one is to require to adjust the position of damping ink roller to the liquid medicine feed rolls of possess hydrophilic property individually with accurate way, and adjusts the installation site of damping ink roller to the lithographic printing-plate cylinder individually with accurate way.
Be at dampening device and manipulate when middle, the toggle that uses in the power transmission moves to the top in centre, has so just avoided because to many problems that compressed-air actuated pressure oscillation produced of pneumatic power transfer device supply.
In addition, in most preferred embodiment, the cross-over connection roller is installed by eccentric bush, thereby has guaranteed the suitable installation site of cross-over connection roller to the damping ink roller, no matter and the damping ink roller is to be not always the case at operating position or at off position.
At last, water is to get on by the liquid medicine feed rolls that multi-strand flow is ejected into possess hydrophilic property, rather than with traditional in water tank the mode of rolling roller.So just guaranteed that those might take up fiber and other chip of coming originally and just be eliminated from water tank before they may enter printing machine.

The function of stop screw 62 is to prevent counterclockwise rotation of suspension 51 and exceed a predetermined limit, and this predetermined limit is determining the off position of damping ink roller 24.Limit stops screw 63 is determining the scope that damping ink roller suspension 51 can move in the clockwise direction, thereby this screw 63 has also just determined damping ink roller 24 and the exact position that contacts engagement that hydrophilic roller 22 is arranged.Also to be described in further detail hereinafter about these.
Referring now to Fig. 3, arrives Fig. 6.A horizontal pivot 64 is bearing between two opposed side edges of frame 12.Long lever arm 65 is installed on the pivot 64 so that lever arm can rotate in the outside of frame 12 again.Articulated linkage 66 couples together the extendible bar 67 of lever arm 65 with pneumatic power conveyer 68.As shown in Figure 1, power transmission 68 can be hinged on the frame 12, and it includes air supply source and exhaust line.
The structure of each component parts and installation are as shown.The withdrawal of pneumatic power conveyer 68 makes roller 22,23 and 24 be in the position shown in Fig. 5.Hydrophilic roller 22 and (just as them contacting the meshing relation of being had in each position of this device) among dancer rools 23 is in rotating engagement are arranged, and damping ink roller 24 then is in roller 22 position contacting that promptly do not contact with plate cylinder 13 also not with possess hydrophilic property.Along with the stretching, extension of pneumatic power transfer device 68, lever arm 65,72 and connecting rod 73 begin to limit the position from (shown in Fig. 5) and have moved to (shown in Fig. 3) another limits the position.At this moment, damping ink roller 24 contacts engagement with the roller 22 of possess hydrophilic property.The degree of this engagement is accurately limited by limit stops screw 63.
When plane confined planes 55 contacted with limit stops screw 63, pneumatic power conveyer 68 was just partly stretching.The further stretching, extension of pneumatic power conveyer 68 makes the unrolling axis of rotation (being the revolution axial line of the roller 22 of possess hydrophilic property) of this suspension bracket of whole main supporting suspension bracket 31 do counterclockwise rotation.And the rotation of the inhour of whole supporting suspension bracket 31 makes damping ink roller 24 contact with the existence of plate cylinder 13 owing to limit stops device 81, will specifically introduce hereinafter about limit stops device 81.
Referring now to Fig. 1, arrives Fig. 3.Limit stops device 81 is made of a L shaped part 82 in addition specifically, and the support straight up of L shaped part 82 in addition is fastened on the side leading supporting suspension bracket 31 (securing member 83 only can be seen in Fig. 1) by means of a suitable fasteners 83.Referring again to Fig. 2, the L shaped horizontal arm end of part 82 in addition has a bolt 84, has an adjustable locking nut on the bolt.Helical spring 85 is installed in the end of bolt 84 and between a groove on the frame 12.
Referring now to Fig. 3.The L shaped horizontal arm end of part 82 in addition has a hexagonal head screw 86, and when pneumatic power transfer device 68 was in wide-spread position, the bottom of hexagonal head screw 86 contacted with frame 12.Hexagonal head screw can be adjusted, so that can determine the contact position of damping ink roller 24 on plate cylinder 13.With a nut 86a hexagonal head screw 86 is locked on the desired position.
Referring now to Fig. 2 and Fig. 3.Cross-over connection roller 25 supports by cross-over connection roller frame 91 at two ends.The 91 hinged installations of cross-over connection roller frame can be moved cross-over connection roller frame 91 around the revolution axle center string pendulum of inking roller 15.Roller frame 91 has an eccentric stent 92, and eccentric stent 92 is provided with dog screw 93 so that the revolution axle center line position of cross-over connection roller 25 is adjusted, thereby guarantee with cross-over connection roller 25 and with the even contact of inking roller 15.
The axial line that cross-over connection roller frame 91 is unrolling inking roller 15 freely rotates, thereby makes cross-over connection roller 25 can both contact with damping ink roller 24 in the whole range of movement of damping ink roller 24, and can keep simultaneously suitable the contacting between cross-over connection roller 25 and the inking roller 15.So, no matter pneumatic power transfer device 68 is in retracted mode or is in extended configuration, cross-over connection roller 25 and inking roller 15 and damping ink roller 24 boths are in continuous suitable contacting among the engagement all the time.
When the running of whole device, under the situation when being in retracted position for pneumatic power transfer device 68, each constitutes other part and is in Fig. 5 and the position shown in Figure 6.Water is sprayed onto on the roller 22 of possess hydrophilic property continuously by feed pipe 42, at this moment dancer rools 23 and the roller 22 of possess hydrophilic property be in rotate contact among, also has the property of smearing motion simultaneously, so that control the thickness of hydrophily roller 22 lip-deep water layers or moisture film equably.In this position, damping ink roller 24 does not contact with hydrophilic roller 22, but keeping with cross-over connection roller 25 between contact.And inking roller 15 does not at this moment contact with plate cylinder 13 as traditional actual conditions yet.Therefore, above-mentioned information slip understands that printing machine 11 is not carry out presswork.
Because lithographic plate is installed on the plate cylinder 13 and (does not represent this installation in the accompanying drawing), the starting of the presswork of printing machine 11 is to be realized by the extended position that pneumatic power transfer device 68 moves to it.During the presswork starting, 24 beginnings of damping ink roller contact with hydrophilic roller 22 according to the mode of above describing, and only contact realizes by adjusting limit stops screw 63.
Contacting with hydrophilic roller 22 before the engagement, damping ink roller 24 by its with the contacting of cross-over connection roller 25 of reciprocally swinging quilt be with and rotated, the result makes has the layer of even ink lay on the surface of damping ink roller 24 again.It is in case engages with hydrophily roller 22, hydrophily roller 22 just with one deck water layer or moisture film " roll extrusion " to the surface of damping ink roller 24, the velocity of rotation of roller 22 is more bigger.After having received one deck water from hydrophily roller 22, damping ink roller 24 contacts with plate cylinder 13 with regard to preparing.The further stretching, extension of pneumatic power transfer device 68 makes damping ink roller 24 enter with plate cylinder 13 in the mode of above having described and contacts that the suitable contact between the two is then realized by the position of adjusting hexagonal head screw 86.When the two contacted, an amount of liquid medicine that damping ink roller 24 is just accurately controlled a warp immediately added on the lithographic plate on the plate cylinder 13.In Fig. 4, show this joint at Fig. 1, also shown the rolling engagement between the lithographic plate on inking roller and the plate cylinder 13 simultaneously.
When pneumatic power conveyer 68 was withdrawn into the non-job position of printing machine, damping ink roller 24 at first disengaged with plate cylinder 13, disengaged with hydrophilic roller 22 again then.
As mentioned above, dampening device of the present invention can be applied to the liquid medicine amount that a warp is accurately controlled on the lithographic plate equably, thereby can obtain good printing quality. Simultaneously, dampening device of the present invention has also avoided not wishing the excessive printing ink that produces and the blending of liquid medicine. The blending of this printing ink and liquid medicine can produce emulsification, thereby printing quality is degenerated.
