Description

The ink feeder of printing machine and printing ink removing device

Technical field

The present invention relates to high viscosity fluid is supplied with the device of the surface of revolution, especially ink feeder and printing ink removing device about being applicable to rotary press of offset printing preferably.

Background technology

With full-bodied fluid supply the carrying out ink feeder of the device of the rotating surface of revolution just like the forme that inking is printed.

Figure 24 is the structure chart of facing of the rotary press of offset printing that prints of a kind of no switching regulator ink feeder that is using before utilizing, and it illustrates carries out the wherein example of the part of a kind of color printing.

As shown in figure 24, on the direction identical, disposing inking flat board 12 with axial (width) of duct cylinder 1, outer peripheral face from dull and stereotyped 12 duct cylinder 1 that the inking of certain thickness is being rotated of this inking, this duct cylinder is driven by the motor that separates with the basic machine that prints, can carry out speed control separately, to rotate than basic machine speed speed slow, that can adhere to printing ink.

And be under the state of once setting the gap between this inking dull and stereotyped 12 and duct cylinder 1 surface, to print.

And the inking flat board 12 that on the no switching regulator ink feeder that this high viscosity is used, is being used so far, do not cut apart along the width of duct cylinder 1, can not change ink colors along the width of duct cylinder 1.

For this reason, propose a kind of scheme, that is, a plurality of ink tank cylinders 2 are set, on each width, can both supply with uniform printing ink by the duct cylinder 1 that broad ways separates towards the width of duct cylinder 1 about inking flat board 12.

In Figure 24, the duct cylinder 1 of supplying with printing ink and pushed between driven printing ink handing-over cylinder 3 with basic machine speed, carry out slippage and carry out slippage metering (ス リ ッ プ メ リ Application グ) simultaneously in its part of nipping, printing ink is handed off on the printing ink handing-over cylinder 3.

Then printing ink is supplied with the cylinder group 4 that is made of a plurality of cylinders from printing ink handing-over cylinder 3, be fed to the forme 6 that is bonded on plate cylinder 45 outer peripheral faces through the painting roller 5 in this cylinder group 4.

And under the occasion of carrying out offset printing,, also supply with humidification water by damping device 29 except above-mentioned printing ink is fed on the forme 6.

Like this, the printing ink of supplying with forme 6 through duct cylinder 1, printing ink handing-over cylinder 3, cylinder group 4 backs is to be supplied to after broad ways is formed certain printing ink thickness, is printed on the paper that navigates between the oppositely-arranged rubber cylinder 46 through rubber cylinder 46 from forme.

Therefore, do not have the part of printing, promptly along with the part of printing ink from painting roller 5 supply formes 6, although printing ink is formed certain ink film heavy back and supplies with, owing to printing ink is not consumed, thereby the printing ink thickness on the outer peripheral faces such as printing ink group 4 suitable with this part just thickens.

For this reason, wiping cylinder 7 in striking off scraper 8 and being arranged on cylinder group 4 is contacted, striking off scraper 8 by this strikes off the printing ink of the thickness thickening of cylinder group 5, printing ink on the cylinder group 4 whole widths is all consumed equally, even on the width of cylinder group 4, supply with printing ink equably, also can average out with consumption; Even producing the difference of the local consumption figure that is caused by printing, broad ways also can become uniform printing ink thickness.

In the no switching regulator ink feeder quantity of ink governor motion, that carry out inking that this broad ways is segmented is not set, use full-bodied printing ink as far as possible, become a big problem that will obtain high-quality printed matter.

In the past, the applicant proposed in Japanese patent gazette " is willing to flat 2-8147 number " in fact with " the printing ink dump tank cylinder of the ink feeder of no switching regulator " as the device that solves this problem, realization high quality printing.

This device, illustrated in the bottom of Figure 24, be provided with in the bottom of ink tank cylinder 2 one (below be called impeller 9), and this is installed with and is processed into spiral helicine plate, by the effect of this impeller 9, printing ink is moved to be configured in the part of printing ink suction line 44 openings of the ink pumps 10 of ink tank cylinder 2 bottoms.

Owing to being fed to that water on the forme 6 is transferred to the surface of cylinder group 4 grades or being scraped with the state printing ink of sneaking into from damping device 29 in the printing ink enters into 2 li in ink tank cylinder, therefore, this impeller 9 stirs the water that is blended in the printing ink in ink tank cylinder 2, plays the action that water is mixed with printing ink simultaneously.

This device, again with ink tank cylinder 2 in driven impellers 9 accordingly (as shown in figure 25) CD-ROM drive motor 50 is set individually, this CD-ROM drive motor 50 is configured to parallel with ink tank cylinder 2.

In Figure 24, owing to ink pumps 10 is driven individually by motor 49 and is provided with respectively abreast with ink tank cylinder 2, thereby suck printing ink from ink tank cylinder 2 bottoms with printing ink suction line 44, discharge from inking pipe 11, be fed to the inking flat board.

The printing ink suction line 44 and the inking pipe 11 that carry out this printing ink conveying just form long pipeline together.

And, use the rotary press of offset printing of the ink feeder that is provided with such formation to carry out under the colored printing occasion, often to change color of ink on each page paper configuration, that in traveling process, be printed along rubber cylinder 46 widths.

For this reason, now just carrying out such trial, promptly the ink feeder broad ways is being separated, can both supplied with the printing ink of turn colors on each width of the rubber cylinder 46 that prints each page respectively.

In addition, the situation of the ink pumps mode of employed ink feeder is just like United States Patent (USP) 2 in letterpress, 731, " printing machinery be coated with black mechanism " (INKINGMECHANISM FOR PRI NTING MACHINES) and United States Patent (USP) 3 of No. 914, " printing machinery be coated with black mechanism " (INKING MECHANISM FOR PRINTINGMACHINES) of 366, No. 051 proposes, power that form with Mechanical Driven or motor drives the ink feeder of each page respectively.

Figure 26 is the example being contained in the ink feeder on the rotary press of offset printing before the expression, and this rotary press of offset printing is to use integrally-built no switching regulator ink supply system shown in Figure 24.

Among Figure 24 and Figure 26, above-mentioned rotary press is that printing ink 2a is supplied with by the speed control motor that omits expression among the figure, turns round the duct cylinder 1 that drives with the speed lower slightly than basic machine speed, be adjusted to after the regulation thickness by the gap of dull and stereotyped 12 front ends of inking, from and the portion of nipping of 3 formation of printing ink handing-over cylinder printing ink is fed to printing ink handing-over cylinder 3, the ink roller group 4 in downstream, pass through painting roller 5 again with inking forme 6.Above-mentioned printing ink handing-over cylinder 3 is driven with basic machine speed.

Carrying out generally also humidification water being supplied with forme 6 under the offset printing occasion from damping device 29.After a certain amount of printing ink 2a broad ways is supplied with, again with this part printing ink from be wound onto forme 6 on the plate cylinder 45, by the paper that rubber cylinder 46 is being advanced with supplying with switching, on paper, print.Therefore, do not have the part of printing because printing ink 2a is not consumed thereby thickness attenuate not.

Wiping cylinder 7 is configured in the way of above-mentioned ink roller group, by printing ink 2a being struck off with these wiping cylinder 7 contacted scrapers 8 that strike off, at whole width printing ink is consumed thus, even on width, supply with the balance that printing ink 2a also can form and consume equably.

Even be coated with in the black mechanism at the no switching regulator that is not provided with the quantity of ink governor motion that such broad ways segmented, use full-bodied as far as possible printing ink 2a also still to obtain the essential condition of high quality printing product.

In above-mentioned ink feeder 100, be provided with in the bottom of ink tank cylinder 2 and will be processed into that spiral helicine plate is installed in axle 31 peripheries and the impeller 9 that constitutes stirs printing ink 2a by this impeller 9, and impels printing ink 2a to move to the suction inlet of ink pumps 10.The above-mentioned impeller 9 that is arranged in the ink tank cylinder 10 makes its revolution by CD-ROM drive motor (not having expression among the figure).

In the ink feeder before this, printing ink 2a is fed to inking nozzle 511 from ink pumps 10, carries by the revolution of duct cylinder 1 printing ink is fed to dull and stereotyped 12 ones of inking by inking pipe 11.

Yet carrying out under the occasions such as colored printing, change the color of printing ink 2a on the necessary broad ways in each page, above-mentioned ink feeder 100 is made broad ways be divided into a plurality of groups (for example being divided into the 2-4 group), can respectively the printing ink 2 of different colours be supplied with every page structure for the mechanism that this occasion is used.

Gap between above-mentioned inking dull and stereotyped 12 and duct cylinder 1 surface is maintained under the state of once setting prints, but the inking of the no switching regulator ink feeder that high viscosity is in the past used is redressed and 12 is not cut apart by every page, but along the whole axial formation one of duct cylinder 1.

In Figure 26, usefulness ink pumps 10 after 2 outputs of ink tank cylinder, is supplied with inking pipe 11 by pipe joint 333 with printing ink 2a, is ejected on duct cylinder 1 surface from inking nozzle 511.After this, this printing ink 2a is turned round conveying towards the direction of arrow among Figure 26, is adjusted to certain thickness by the inking flat board 12 that is set with holding specified gap, again towards the part transmission of nipping of printing ink handing-over cylinder 3.

And shift the remaining printing ink in back to be carried by further revolution attached to duct cylinder 1 lip-deep state, strike off by the part 334 that strikes off that is installed in inking nozzle 511 belows.Strike off the residual ink that part 334 and above-mentioned inking flat board 12 strike off by this and fall downwards, be recycled in the ink tank cylinder 2.

The inking nozzle 511 of this ink feeder 100 and dull and stereotyped 12 these two upper members of inking that are fastened on the support 151 all are fixed on the device frame, and the cleaning of inking flat board 12 is the center, swings among Figure 26 and undertaken by the state shown in the chain-dotted line with fulcrum shaft 329 support 151 and flat board 12 when replacing the color of printing ink 2a or during maintenance.

When replacing the color of printing ink 2a, the pipe joint 333 that will be arranged on earlier in the way of inking pipe 11 is separated, replace to after the ink tank cylinder 2 of subsequent processing, aforementioned tube joint 333 is connected, will be contained in the drive source shaft coupling 13 of base side and the shaft coupling 14 that is driven of ink pumps 10 sides then and be connected.Then, drive ink pumps 10 and supply with new printing ink, replace printing ink 2a by printing ink extrusion that will be old.The mixed ink of dirt and detergent remover are recovered in another accumulator tank cylinder that does not have expression among the figure, after official hour, after also being about to new printing ink and replacing it, begin next step printing.

Figure 27, Figure 28 represent that the printing ink of rotary press of offset printing strikes off the schematic configuration of scraper portion.In Figure 27-28, the 3rd, printing ink handing-over cylinder, the 7th, the wiping cylinder, the 8th, with the contacted scraper that strikes off of the periphery of this wiping cylinder 7, the 218th, that supports that this strikes off scraper 8 strikes off the scraper supportive device.

In Figure 24-Figure 28, above-mentioned rotary press of offset printing makes duct cylinder 1 drive with the speed revolution lower slightly than basic machine speed by the speed control motor that does not have expression among the figure, printing ink 2a injection is fed on this duct cylinder 1, by the gap of the front end of inking flat board 12 printing ink is adjusted to after the regulation thickness, the portion of nipping that forms between the printing ink handing-over cylinder 3 that is being driven with inking dull and stereotyped 12 with basic machine speed is fed to the printing ink handing-over cylinder 3 in downstream and accepts the ink roller group 4 of usefulness, through painting roller 5 and with inking forme 6.Stay the surplus printing ink there to be carried after the transfer on the above-mentioned printing ink painting roller 1, strike off by the part 334 that strikes off that is installed in inking nozzle 511 belows further to turn round attached to duct cylinder 1 lip-deep state.Strike off the residual ink that part 334 and inking flat board 12 strike off and fall downwards by above-mentioned, be recycled in the ink tank cylinder 72.

In offset machine, from damping device 29 humidification water is fed on the forme 6 usually.Printing ink 2a after the width supply of printing machine is a certain amount of, is printed from the paper that the 6 pairs of switchings of forme that are wound onto on the plate cylinder 45 are being advanced again by rubber cylinder 46.Therefore do not have printing because printing ink 2a is not consumed, the just not attenuation of printing ink thickness.

As the aforesaid method that becomes the inhomogeneous thickness of printing ink 2a stable such scheme was proposed, promptly, strike off printing ink 2a with the scraper 8 that strikes off that joins with wiping cylinder 7 in the way that is provided in the ink roller group, in the whole zone of width printing ink is reclaimed, even supply with printing ink equably, also can average out with consumption at width.

Yet under the occasion of the colored printing of carrying out on the width changing color, ink feeder 100 is made into along the width of cylinder and is divided into a plurality of groups (for example 2-4 groups), can be respectively the printing ink 2a of different colours be supplied with each page or leaf.Print under the state of once setting in the gap between inking dull and stereotyped 12 and duct cylinder 1 surface.

On the other hand, shown in Figure 27,28, because the above-mentioned scraper 8 that strikes off is axially to be integrally formed into a slice along whole wiping cylinder 7, thereby under the ink colors of each page that the horizontal cross direction along paper prints abreast is identical occasion, can give full play to its function, but this structure is being printed under the occasion along cylinder width, every page of color ground that changes printing ink 2a, and the printing ink of adjacent different colours just mixes mutually, is recovered under dirty state.

In a word, Figure 24,25 and ink feeder shown in Figure 26 and Figure 27 and printing ink removing device shown in Figure 28 the following described problem that will solve is arranged.

(1) about Figure 24 and former ink feeder shown in Figure 25

In the former ink feeder of Figure 24-shown in Figure 25, being arranged on the impeller 9 of ink tank cylinder 2 and the motor drive shaft of ink pumps 10 all is provided with respectively abreast with ink tank cylinder 2, ink tank cylinder 2 and ink pumps 10 form separated structures, and printing ink is attracted to the printing ink suction line 44 of ink pumps 10 and the inking pipe 11 that printing ink is supplied with inking flat board 12 from ink pumps 10 is seemed that all the restriction in length, the configuration makes structure also become complicated from ink tank cylinder 2.

Therefore, it is big that pipe resistance becomes, and especially those must attract as the printing ink suction line 44 of the printing ink of high viscosity fluid elongatedly, cause problems such as inappropriate suction is bad easily.

And in ink tank cylinder 2, the peristome that makes printing ink move to printing ink suction line 44 just must have the drive unit of impeller 9, just need drive the CD-ROM drive motor 49,50 (with reference to Figure 25) of this impeller and above-mentioned ink pumps 10 respectively.

In addition, carrying out with such printing machine under the occasion of colored printing, as mentioned above, sometimes need on each page or leaf that prints along rubber cylinder 46 widths, change color, but, as mentioned above, because dull and stereotyped 12 broad ways of inking are not cut apart, therefore can not realize above-mentioned needs.

And, will cut apart based on the ink feeder broad ways of the inking flat board 12 of present proposition, during to each page change color of width, must replace ink feeder based on ink tank cylinder 2.

But, as mentioned above, because printing ink suction line 44 and inking pipe 11 are longer, 2 CD-ROM drive motors 49,50 are set again, thereby the weight when basic machine unloads ink feeder increases, and must dispose the configuration of electric wire, ink feeder with respect to the dress of basic machine, tear difficulty open, pull down and load onto and need take a long time.

(2) about former ink feeder shown in Figure 26

Ink feeder before shown in Figure 26, owing to be the replacement of carrying out ink colors according to above-mentioned program, thereby when replacing to not by the new ink of dirt, dilution, not only need to spend quite a lot of time, and will form the dirty printing ink of quite a large amount of conducts and discarded printing ink at the replacement initial stage.And in this ink feeder, just be connected after corresponding on the position of engagement of stipulating owing to will make drive source shaft coupling 13 and be driven shaft coupling 14, thereby when replacing printing ink as the initial setting situation is forgotten, the problem that shaft coupling can not be connected will take place.

Because of the inking flat board 12 that axially is integrally formed into that is provided with along whole duct cylinder 1,, will make the significantly reduced problem of printing quality thus again so the printing ink of lateral position just mixes easily mutually on the width of adjacency.In addition, the gap along its length of inking flat board 12 also is difficult the adjustment; Again because hydraulic pressure during inking and the pressure (counter-force) when striking off make gap change on the length direction of cylinder of dull and stereotyped 12 front ends of inking, thereby, have the problem that gradation unequal appears in printing surface along the axially difficult printing ink that forms homogeneous film thickness of supplying with of whole duct cylinder 1.

In addition, also have these problems, promptly, at dress, when tearing ink feeder 100 open, printing ink 2a fall from positions such as inking nozzle 511 and inking dull and stereotyped 12 ones and pipe joints 333 disperse, the problem of polluting device periphery, the installation of pipe joint 333, dismounting need the long duration and problems such as operation is relatively poor and more time-consuming during residual ink on removing members such as above-mentioned inking nozzle 511 and inking flat board 12.

(3) about Figure 27 and former printing ink removing device shown in Figure 28

Offset machine carries out the printing of multipage (for example carrying out 4 pages) sometimes abreast at the horizontal cross direction of 1 group of rubber cylinder upper edge paper, and the mutual conversion of this ink colors ground is printed.Be adopted as in the prior art that printing provides, as Figure 27, the method for striking off, reclaim printing ink 2a shown in Figure 28.In the method, make 1 to strike off scraper 8 and contact with wiping cylinder 7, with as the mechanism that the printing ink 2a of remaining residue on ink roller group surface struck off along axial (width) of whole ink roller.Therefore, in this prior art, can take place to make its dirt, thereby make the significantly reduced problem of quality of the aesthetic of printed matter because the printing ink of adjacency is sneaked into the forme rear flank of another kind of color mutually.

In order to be unlikely to take place such dirt, the mechanism that the printing ink that also proposed to strike off stockpiles, but when using this mechanism because the on-stream printing ink that strikes off accumulated, thereby just makes the ink tank cylinder increase, perhaps needs to replace continually printing ink or discarded printing ink.
