Above-mentioned cleaning fluid, dilution and be running water in the present embodiment from the dilution that aforementioned mist injection nozzle (21) (21) is sprayed out.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, in two rollers (1) (2) top 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) lifting (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) action 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) rotation, 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) rotation, 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.
Spray chamber (60) utilizes the high humility of mist maintenance near saturation state.Thereby the molecule that utilizes the rotation of compression roller (2) will cover the dilution on roller surface is transported to printing ink storage part (11) continuously.
When printing ink dilutions such as directly making water drops onto printing ink storage part (11) and plants, 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) surface 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 in the below of compression roller (2) towards this roller (2) than hectare oblique configuration mist injection nozzle (21) (21) in the end in distally, can produce energetically moistening effect is carried out on compression roller (2) surface.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 the narrow and small outlet (66) above the compression roller (2) of spray chamber (60) spills forms high humility atomizing atmosphere near mist of oil storage part (11), therefore suppressed the water evaporates of printing ink storage part (11) and prevented that the viscosity of printing ink from rising.
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 part (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, on one side from this position to the zone that the center side of printing ink storage part (11) moves regulation, 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) decline 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 the mobile of printing ink in printing ink storage part (11).
Secondly, attract under the state of printing ink stopping, promoting the front end that the printing ink supply attracts nozzle (4) from printing ink storage part (11), airtight box body (3) is positioned at and leaves the position that attracts the position, turns back to the central portion of printing ink storage part (11) in the present embodiment.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).
When airtight box body (3) finishes at the printing ink circulation pattern, be in holding state at the central portion of printing ink storage part (11).
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, by carrying out in printing ink storage part (11), to produce continuous ink flow repeatedly, printing ink is stirred 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 portion.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).
In the position with diluent liquid supply nozzle (7) (7) (70) supply diluent liquid, 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 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, thereby can obtain to regulate the effect of the ink viscosity in the print cartridge (31).
(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).
Make airtight box body (3) slip and utilize the printing ink supply that is assemblied on this box body (3) to attract nozzle (4) to attract the interior printing ink of 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 of utilizing 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, making the printing ink supply attract nozzle (4) and waste liquid to reclaim nozzle (5) rises, roller (1) (2) is rotated, airtight box body (3) is slided and from cleaning fluid supply nozzle (34) to the cleaning fluid (Fig. 4 B) that constitutes by water of executing the about 100cc of ink roller (1) distribution.
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 fluid 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) rotation, attract the new printing ink of nozzle (4) supply from the printing ink 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) side, 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.
Tap (81) in baffle component (8) is located, owing to acted on the attraction of aforementioned recycling can (50), therefore, the waste liquid of the tap (81) that is extruded baffle component (8) is attracted in the recycling can (50).
Described as described above, flow to baffle component (8) side by promoting waste liquid, the liquid level of waste liquid raises gradually, is blocked the opening of printing ink storage part (11) side 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) end 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 that the printing ink supply attracts the number of nozzle (4) and along the length direction configuration of printing ink storage part (11), do not make the printing ink supply attract state that nozzle (4) slides attraction printing ink down.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) towards with the opposite direction of rotation of executing ink roller (1), the back-up block (23) that supports band-like plate (22) constitutes the wall of printing ink storage part (11), 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.
