Cleaning fluid supply nozzle 34,34 is positioned at the top of executing ink roller 1, cleaning roller 1,2 o'clock, the cleaning fluid of ormal weight with link to each other by the cleaning fluid feeding mechanism (not shown) of spraying or drippage scatters.
In addition, dispose the dilution supply nozzle 7,7 that is positioned at not with the position of airtight box body 3 collisions in the both end sides of aforementioned printing ink storage part 11.
Above-mentioned cleaning fluid, dilution and the dilution of spraying out from aforementioned mist injection nozzle 21,21 are running water in the present embodiment.Self-evident, also can add additive, and can adopt and the corresponding liquid of ink characteristics it.
Aforementioned sliding driving device 25 makes airtight box body 3 slide along printing ink storage part 11, as this example of structure, can consider to adopt structure shown in Figure 8.Wherein, above two rollers 1,2 track 26 is set along printing ink storage part 11, the roller 27,27,27,27 that will be connected with airtight box body 3 embeds in the track 26.Airtight box body 3 moves along track 26.In addition, as previously described, the lifting drive 32 that is installed on the airtight box body 3 makes nozzle installing plate 33 liftings (with reference to Fig. 1).
Sliding driving device 25 at least can be described in the back printing ink reclaim between cleaning fluid take-back model and two patterns of printing ink circulation pattern and change.Printing ink during color replacement reclaims under the cleaning fluid take-back model, makes airtight box body 3 move back and forth one or many across the whole length of printing ink storage part 11, so that reclaim printing ink and cleaning fluid.Its action is shown in Fig. 4 A to Fig. 4 C.The printing ink circulation pattern is the pattern in the print run, and it moves shown in Fig. 3 A to Fig. 3 D.
Below, the printing ink circulation pattern of this printing machine, each action that printing ink reclaims the cleaning fluid take-back model are described.
(the printing ink supply of printing ink circulation pattern)
Fig. 3 A to Fig. 3 D is the key diagram that the printing ink supply attracts nozzle 4 actions in the explanation printing ink circulation pattern, from the upstream side of paper supply, promptly observe printing machine Fig. 1 from the F direction.For the ease of diagram, omitted lid 6 and waste liquid and reclaimed nozzle 5.
When supply printing ink in the printing ink storage part 11 of sky, Yi Bian airtight box body 3 is slided along printing ink storage part 11, Yi Bian attract nozzle 4 supply printing ink from the printing ink supply that is assemblied on the airtight box body 3.At this moment, make and execute ink roller 1 and compression roller 2 rotations, be attached on the roller 1,2, simultaneously, printing ink is stirred at the boundary line that prevents the printing ink liquid level.
Liquid level as if printing ink being supplied to setting then stops the supply of printing ink by the action of liquid level sensor, airtight box body 3 once had been back to the central authorities (Fig. 3 A) of printing ink storage part 11.At this moment, attract nozzle 4 to be immersed in the printing ink storage part 11 the printing ink supply, the printing ink of being supplied is approximately 2 liters.Then, keep making the state of two rollers, 1,2 rotations, the beginning print run.
In above-mentioned printing ink supply and print run, spray diluent liquid and cover the surface of compression roller 2 from mist injection nozzle 21,21 with the molecule of diluent liquid, moistening to carry out energetically, simultaneously, make in the spray chamber 60 to be full of mist.
When printing ink dilutions such as directly making water drops onto in the printing ink storage part 11, because the characteristic (proportion, viscosity etc.) of dilution and printing ink is different, so diluent liquid can be not directly and the printing ink affinity, so be difficult to mixing.Yet in this example, the molecule of the diluted liquid of side face of compression roller 2 is moistening, and this moistening rotation by roller 2 is brought in the printing ink storage part 11.Whereby, the moisture on compression roller 2 surfaces and the direct affinity of printing ink in the printing ink storage part 11, and mix well, so the viscosity of printing ink can not produce inhomogeneous.
As present embodiment, by below compression roller 2 towards this roller 2 than the sloped-end in distally configuration mist injection nozzle 21,21, can produce energetically moistening effect is carried out on compression roller 2 surfaces.That is, because the jet length of mist injection nozzle 21,21 is long, so can make mist carry out moistening to the relative broad range of compression roller 2.
In addition, because the mist that spills from the narrow and small outlet 66 of compression roller 2 tops of spray chamber 60 forms high humidity temperature atomizing atmosphere mist of oil storage part 11 near, so suppressed the water evaporates of printing ink storage part 11 and prevented the viscosity rising of printing ink.
In addition, the purpose that is full of by mist of the inside that makes the lid 6 that includes compression roller 2 is openly reported in flat 6-947 number in Japan's special permission and is disclosed.Yet in the present embodiment, mist injection nozzle 21,21 is configured in the below of compression roller 2, and by the rotation of compression roller, the molecule that covers the dilution on roller surface is sent in the printing ink storage part 11.Therefore, even the top board 65 of compression roller 2 and lid 6 is approaching, also can dilute printing ink effectively.
(printing ink circulation)
Operate the guidance panel (not shown) of printing machine as the user, when setting the program of printing ink circulation, the printing ink supply attracts nozzle 4 in the position shown in Fig. 3 A, supplies about 6 seconds printing ink with the state that rises to lifting position by lifting drive 32 in the print cartridge 31 of airtight box body 3.In addition, when printing operation, also can set the program of printing ink circulation consistently.
After this, shown in Fig. 3 B, airtight box body 3 moves to an end of printing ink storage part 11.The printing ink supply attracts nozzle 4 to drop to the centre position at its place, shift position, in the printing ink of printing ink supply attraction nozzle 4 immersion printing ink storage parts 11 (state shown in Fig. 3 B solid line).After printing ink being recovered in the airtight box body 3 with about 2 seconds time, move the zone of regulation on one side to the center side of printing ink storage part 11 from this position, move about 50cm in an embodiment, Yi Bian attract the printing ink (position shown in the line of Fig. 3 B kind single-point) of printing ink storage part 11.This zone becomes first recovery zone.
When the printing ink supply attracted nozzle 4 to attract printing ink in first recovery zone of printing ink storage part 11, the liquid level of this recovery zone descended, and from the center side of printing ink storage part 11 to the first recovery zone moving ink, thereby printing ink produces and flows.
The moving ink supply attracts nozzle 4 in first recovery zone, has the effect that stirs printing ink with this.
Then, stop the attraction of printing ink, from printing ink, promote the front end that the printing ink supply attracts nozzle 4, airtight box body 3 is moved to the end of the opposition side of printing ink storage part 11.At its place, shift position the printing ink supply is attracted in nozzle 4 declines and the immersion printing ink (position shown in the solid line in by Fig. 3 C).The same with the situation of in first recovery zone, being carried out, after in airtight box body 3, reclaiming printing ink with about 2 seconds, only in zone as hereinbefore, make airtight box body 3 and printing ink supply attract nozzle 4 to move on one side, Yi Bian attract printing ink (by the position shown in the single-point line of Fig. 3 C) to the center side of printing ink storage part 11.With aforementioned the same, the liquid level of this recovery zone (being called second recovery zone) descends and from the center side moving ink of printing ink storage part 11, produces flowing of printing ink in printing ink storage part 11.
Secondly, attract under the state of printing ink stopping, from printing ink storage part 11) promote the printing ink supply and attract nozzle 4) front end, airtight box body 3 is positioned at and leaves the position that attracts the position, turns back to printing ink storage part 11 in the present embodiment) central portion.In this position, the printing ink supply attracts nozzle 4 still to be in lifting position, to printing ink storage part 11 supply printing ink.By utilizing aforesaid liquid level sensor to control, liquid level can not rise to more than the height of setting.
In print run, carry out above-mentioned circulation repeatedly, printing ink is circulated between printing ink storage part 11 and print cartridge 31.
Airtight box body 3) when the printing ink circulation pattern finishes, at printing ink storage part 11) central portion be in holding state.
In addition, in print run, supply an amount of diluent liquid from the diluent liquid supply nozzle 7,7 of printing ink storage part 11 both end sides and the diluent liquid supply nozzle (70) that is assemblied on the airtight box body 3.
As mentioned above, in print run,, printing ink is stirred by carrying out in printing ink storage part 11, to produce continuous ink flow repeatedly in the attraction of printing ink storage part 11 both end sides printing ink with at the inking of printing ink storage part 11 central portions.Particularly, because printing ink flows,, increased mixing effect between the both end sides of printing ink storage part 11 so displacement becomes greatly.
And the printing ink supply attracts nozzle 4 to move with the airtight box body 3 that stores printing ink, thereby the path that printing ink flows through is shorter, needn't need very long circulating path as before, thereby can prevent that ink viscosity from rising.
If surplus is left in the lower end of the following end distance printing ink storage part 11 of nozzle 4, then also can move it making the printing ink supply attract nozzle 4 to be immersed under the state in the printing ink storage part 11.
Supplying the position of diluent liquid with rare liquid supply nozzle 7,7,70 that falls, ink viscosity descends.Yet, by attracting the ink flow that produces by printing ink in two recovery zones that attract nozzle 4 in above-mentioned printing ink supply and replenish the ink flow that the printing ink that uses in the printing machine and reduce causes, can prevent that ink viscosity from rising and prevent the ink viscosity inequality.
Especially, in embodiment, utilize the printing ink supply to attract nozzle 4, make, thereby can obtain to regulate the effect of the interior ink viscosity of print cartridge 31 because of the supply from the diluent liquid of diluent liquid supply nozzle 7,7 is recycled in the print cartridge 31 printing ink at the temporarily-depressed position of ink viscosity.
(printing ink reclaims the cleaning fluid take-back model)
After the printing of ormal weight finishes, must carry out color of ink corresponding to subsequent printings and change.At this moment, wash attached to the printing ink on the roller 1,2.
Fig. 4 A to Fig. 4 C is that the waste liquid of explanation printing ink recovery cleaning fluid take-back model reclaims the key diagram of the action of nozzle 5.
When carrying out the printing ink replacing, the rotation of stop roller 1,2 utilizes lifting drive 32 to make the printing ink supply attract nozzle 4 and waste liquid to reclaim the down position (Fig. 4 A) that nozzle 5 is reduced to printing ink storage part 11.The suction tube 51 that links to each other with waste liquid recovery nozzle 5 is flexible, does not hinder waste liquid to reclaim the decline of nozzle 5.
The printing ink that makes airtight box body 3 slide and utilize the printing ink supply that is assemblied on this box body 3 to attract nozzle 4 to attract in the printing ink storage part 11.At this moment, do not attract waste liquid to reclaim nozzle 5.
As among the embodiment, if adopt the mode utilize vacuum suction printing ink, make the printing ink supply attract nozzle 4 across the total length of printing ink storage part 11 with carry out one, twice reciprocating motion, then can attract nearly all printing ink in the printing ink storage part 11.
Then, make the printing ink supply attract nozzle 4 and waste liquid to reclaim nozzle 5 and rise, roller 1,2 is rotated, airtight box body 3 is slided and from cleaning fluid supply nozzle 34 to executing the cleaning fluid (Fig. 4 B) that constitutes by water that ink roller 1 scatters about 100cc.
To be the film shape attached to executing printing ink on the ink roller 1 almost by flush away, scrub raffinate is retained in the printing ink storage part 11.Being the film shape is micro-attached to the printing ink of executing on the ink roller 1, and printing ink is water-based, thereby the amount of cleaning required cleaning fluid seldom.
The rotation of stop roller 1,2 makes the printing ink supply attract nozzle 4 and waste liquid to reclaim the down position place that nozzle 5 drops to printing ink storage part 11.Stop the attraction that the printing ink supply attracts nozzle 4.In this state, the airtight box body 3 that slides also only attracts waste liquid to reclaim nozzle 5, so that waste liquid is attracted in the recycling can 50.
If carry out the attraction of recycling can 50, the tap 81 to the fishplate bar parts 8 at printing ink storage part 11 two ends also acts on attraction simultaneously, then also will clean waste liquid from baffle component 8 and be recovered to (Fig. 4 C) the recycling can 50.The same when reclaiming printing ink, if make waste liquid reclaim nozzle 5 across the total length of printing ink storage part 11 with reciprocal one, twice back and forth, then can attract nearly all cleaning fluids in the printing ink storage part 11.After reclaiming, sealing box body 3 is in holding state at the central portion of the length direction of printing ink storage part 11.
As previously described, when printing ink is changed, can almost can't harm lost territory recovered oil China ink, accompany therewith, the consumption of the cleaning fluid that cleaning roller is required seldom, and the concentration of cleaning waste liquid is also very low.Therefore, the processing of cleaning waste liquid does not need very big equipment, thereby can reduce the operating cost of liquid waste processing.
For colour changing, take off, change the print cartridge 31 in the airtight box body 3.
Then, two nozzles 4,5 are risen, make roller 1,2 rotations, attract nozzle 4 from the printing ink supply) the new printing ink of supply.
In this case, the printing ink supply attracts nozzle 4 laterally not move, and still is positioned at position of readiness.And, help carrying out the attraction of recycling can 50.
Shown in Fig. 5 A, the ink I that flows out from nozzle 4 in the bottom of printing ink storage part 11 to baffle component 8 side flow.Do not leave a small amount of cleaning fluid H that is reclaimed nozzle 5 recovery by waste liquid in the bottom of printing ink storage part 11.Yet, to the flowing of baffle component 8 sides, promote residue waste liquid H by ink I and flow by ink I.
Because proterties such as the proportion of the flow tendency of ink I and waste liquid and printing ink, viscosity are different, therefore, waste liquid H mixes hardly with ink I, is pushed to flow to baffle component 8.
Shown in Fig. 5 B, ink I and waste liquid H are near baffle component, and the height of liquid level rises simultaneously.
At tap 81 places of baffle component 8,, therefore, the waste liquid of the tap 81 that is extruded baffle component 8 is attracted in the recycling can 50 owing to acted on the attraction of aforementioned recycling can 50.
Described as described above, flow to baffle component 8 sides by promoting waste liquid, the liquid level of waste liquid raises gradually, is blocked the opening of printing ink storage part 11 sides of tap 81 by liquid level.Therefore, can prevent that air from spilling from tap 81, thereby can attract waste liquid with very strong attraction.
Printing ink be recovered to from tap 81 recycling can 50 will finish before in, stop the attraction of recycling can 50.Measure and flow to the time of printing ink storage part 11 ends in advance by the printing ink that timer is set the central portion be supplied to printing ink storage part 11, perhaps, can realize aforementioned operation with this at the liquid matter detector of the end of printing ink storage part 11 configuration detection waste liquid and printing ink liquid matter difference.In fact, the about maintenance of described waste liquid recovery is 40 seconds.
As mentioned above, can reclaim whole cleaning waste liquids basically.As the waste liquid that the wall of moistening printing ink storage part 11 left behind, the waste liquid that perhaps is not recovered all is micro-, even thereby mix also with new printing ink and can not influence color of ink.
In this example, be provided with two printing ink supplies and attract nozzle 4,4, in two recovery zones, immerse in the printing ink and also move.Replace, can consider to increase the printing ink supply and attract the number of nozzle 4 and, under the state that does not make the printing ink supply attract nozzle 4 to slide, attract printing ink along the length direction configuration of printing ink storage part 11.Yet, in this case, relatively poor to the mixing effect of printing ink.
And in the present embodiment, the central portion supply printing ink to printing ink storage part 11 attracts in the end.Replace, also can attract at central portion at the end of printing ink storage part 11 supply printing ink.
In addition, in the above-described embodiments, execute the extruder member of the printing ink on the ink roller 1,, be not limited to this though adopt compression roller 2 as extruding.For example, as shown in Figure 6, also can be with respect to executing the total length pressurization contact band-like plate 22 of ink roller 1 across this roller 1, between forms printing ink storage part 11.
Under the situation of Fig. 6, band-like plate 22 is towards the direction opposite with the rotation of executing ink roller 1, and the back-up block 23 that supports band-like plate 22 constitutes the wall of printing ink storage part 11, and band-like plate 22 is also used as the bottom of printing ink storage part 11.
In the above-described embodiments, to the printing ink supply of printing ink storage part 11, to reclaim be to be undertaken by pressurization airtight box body 3 in and decompression, the recovery of cleaning waste liquid is to be undertaken by the decompression of recycling can (50).Yet, also can adopt tubing pump to carry out oil supplying, recovery, clean the recovery of waste liquid.
In the above-described embodiments, shown in Fig. 5 A, 5B, when utilization is supplied to the ink I of printing ink storage part 11 that residue waste liquid H is expressed to the end of printing ink storage part 11, reclaim remaining waste liquid by recovery tube 52 from the tap 81 of baffle component 8.Yet, be not limited thereto, baffle component 8 is separated with the end face of roller 1,2, reclaim the waste liquid that flows down from the end of printing ink storage part 11.
The invention is not restricted to water color ink, the glycols printing ink low for viscosity, that rate of drying is good also can be implemented.
