Injection of the drop of ink from ink gun 40.
With reference to 2~Fig. 7 of figure, ink-jet apparatus is illustrated from sequence of the supply ink until spraying ink.
As shown in Fig. 2, storing ink 70 in main tank 21.Control device 60 controls open and close valve 35,55 and becomes pass
Closed state.At this point, ink gun 40 is in halted state.Control device 60 makes pump 22,23 work.Ink in main tank 21 as a result,
70 are flowed into surge tank 30 via pump 22.If ink 70 continues to flow into surge tank 30, the liquid level in surge tank 30 can be gradual
Rise.
As shown in figure 3, after the liquid level in surge tank 30 reaches the horizontal position of outflux 32, open and close valve 35 is opened.
Whether reach the horizontal position of outflux 32 as liquid level, can be judged according to the measurement result of level transducer 36.
If open and close valve 35 remains off, after liquid level reaches the horizontal position of outflux 32, ink 70 can pass through
Outflux 32 flows out from surge tank 30 and is supplied to ink gun 40.If however, opening open and close valve 35, ink 70 will not flow out,
Liquid level continues to rise more than the horizontal position of outflux 32.
As shown in figure 4, if the liquid level in surge tank 30 reaches the position higher than the horizontal position of outflux 32, dress is controlled
Set 60 closing open and close valves 35.Here, outflux can be compared to detect that liquid level reaches according to the measurement result of level transducer 36
The case where high position in 32 horizontal position.If closing open and close valve 35, the liquid level in surge tank 30 stops rising, and ink 70 is logical
Outflux 32 is crossed to begin to flow out.
If as shown in figure 5, closing open and close valve 35, ink 70 is supplied to ink gun 40 via surge tank 30.If ink gun
40 are filled by ink 70, then the ink 70 flowed out from ink gun 40 is flowed into surge tank 50 by inflow entrance 51.
As shown in fig. 6, after the liquid level in surge tank 50 reaches the horizontal position of outflux 52, control device 60 is opened
Open and close valve 55.Whether reach the horizontal position of outflux 52 as liquid level, can according to the measurement result of level transducer 56 come
Judged.If opening open and close valve 55, the liquid level in surge tank 50 continues to rise more than the horizontal position of outflux 52.
As shown in fig. 7, if the liquid level in surge tank 50 reaches the position higher than the horizontal position of outflux 52, dress is controlled
Set 60 closing open and close valves 55.After closing open and close valve 55, the ink 70 in surge tank 50 is flowed out by outflux 52.From buffering
The ink 70 that tank 50 flows out is recovered to main tank 21 via pump 23.
As shown in figure 8, in the state of closing open and close valve 35,55, ink 70 is recycled in circulating path 20.At this
Under state, control device 60 makes ink gun 40 work.As a result, ink is sprayed from the nozzle bore 41 of ink gun 40 towards substrate 43
Drop.
With the pulsation of the ink flux ejected from pump 22, the liquid level in surge tank 30 can upper and lower displacement.Similarly, with
The pulsation of the ink flux sucked by pump 23, the liquid level in surge tank 50 also can upper and lower displacement.By in surge tank 30 and 50
Liquid level upper and lower displacement, the pulsation of ink flux generated in pump 22,23 absorbed.Therefore, it is flowed into ink gun 40
The pulsation of ink flux and the ink flux flowed out from ink gun 40 reduces.As a result, it is possible to steadily be sprayed from ink gun 40
Penetrate ink.
Then, by being compared with comparative example shown in Fig. 9, the excellent effect of above-described embodiment is illustrated.
The skeleton diagram of ink-jet apparatus based on comparative example is shown in Fig. 9.In a comparative example, in surge tank 30,50 simultaneously
It is not installed with open and close valve 35,55 (Fig. 1) and level transducer 36,56 (Fig. 1).
In a comparative example, after the liquid level in surge tank 30 reaches the horizontal position of outflux 32, if ink is flowed into
Surge tank 30, the then ink for being equivalent to influx are flowed out by outflux 32.Similarly, the liquid level in surge tank 50 reaches stream
After the horizontal position of outlet 52, if ink is flowed into surge tank 50, the ink for being equivalent to influx is flowed by outflux 52
Go out.
Therefore, the liquid level in surge tank 30 maintains the horizontal position almost the same with the horizontal position of outflux 32, and
The upper and lower displacement near the horizontal position.If liquid level becomes to set low than the horizontal position of outflux 32, surge tank 30 can be caused
Interior air is supplied to ink gun 40 by outflux 32.As a result, the ink injection of ink gun 40 becomes unstable.
Similarly, the liquid level in surge tank 50 maintains the horizontal position almost the same with the horizontal position of outflux 52,
And the upper and lower displacement near the horizontal position.By the displacement of liquid level, air in surge tank 50 by outflux 52 with
Ink flows out together.Bubble can be mixed into the ink recycled in circulating path 20 as a result,.If the bubble being mixed into ink is logical
It crosses circulating path 20 and reaches ink gun 40, then the ink injection of ink gun 40 will become unstable.
In the above-described embodiments, as shown in figure 8, the liquid level in surge tank 30 maintain it is higher than the horizontal position of outflux 32
Position.Due to liquid level upper and lower displacement near the position higher than the horizontal position of outflux 32, outflux 32 is always
Positioned at the position than liquid level more on the lower.Therefore, it is possible to prevent the air in surge tank 30 from entering cycle by outflux 32
Path 20.Similarly, it can prevent the air in surge tank 50 from being entered in circulating path 20 by outflux 52.
It, preferably will be from the horizontal position of outflux 32 to liquid level in order to improve the effect for preventing air from entering circulating path 20
The height until liquid level when dropping to minimum is set as more sufficiently large than the displacement amplitude of liquid level.For example, it is preferable to will be from outflux 32
Horizontal position to liquid level when liquid level drops to minimum until height be set as liquid level displacement amplitude 2 times or more.
In the case where ink gun 40 works, if inflow entrance 31 exposes in the top of liquid level, in ink from inflow entrance 31
Bubble is easy tod produce when being fallen towards liquid level in ink.The generation of bubble in order to prevent, preferably by the horizontal position of inflow entrance 31
It is set as identical or lower than it as the horizontal position of outflux 32.Similarly, in surge tank 50, it is also preferred that by the water of inflow entrance 51
It is identical or lower than it as the horizontal position of outflux 52 that prosposition, which installs,.
In the above-described embodiments, open and close valve 35 is closed when as shown in Fig. 2, being initially supplied ink.Later, as shown in figure 3,
Liquid level in surge tank 30 opens open and close valve 35 after reaching the horizontal position of outflux 32.As other methods, also may be used
To open open and close valve 35 from being initially supplied ink.In this case, as shown in figure 4, the liquid level in surge tank 30 is more than
Open and close valve 35 is closed when the horizontal position of outflux 32.It is equally possible that opening opening and closing from being initially supplied ink
Valve 55.
Then, circulating path 20, pump 22,23, the cleaning method of surge tank 30,50 and ink gun 40 are carried out with reference to figure 10
Explanation.
The skeleton diagram of ink-jet apparatus when cleaning is shown in Figure 10.The ink in main tank 21 is discarded before washing.
Moreover, by making pump 22,23 work, the ink in circulating path 20 is recovered to main tank 21 and is discarded.Remain on buffering
Ink in tank 30,50 is then discarded by opening drain valve 37,57.
After ink in discarded main tank 21 and circulating path 20, cleaning solution 71 is filled in main tank 21.In main tank
It is filled in 21 after cleaning solution 71, pump 22,23 is made to work.Cleaning solution 71 is recycled in circulating path 20 as a result,.Buffering
The liquid level of cleaning solution 71 in tank 30 maintains the high position of liquid level of the ink 70 when being sprayed than ink shown in Fig. 8.It is this
State can by postpone closing open and close valve shown in Fig. 4 35 at the time of by realize.Similarly, the cleaning solution 71 in surge tank 50
Liquid level be also maintained at the high position of liquid level of the ink 70 when being sprayed than ink shown in Fig. 8.
If the liquid level of the cleaning solution 71 in surge tank 30,50 is set as higher, flow is transmitted in the inhibition of surge tank 30,50
The function of pulsation will reduce.Therefore, the pulsation of the cleaning solution flow generated in pump 22,23 can be transmitted to ink gun 40.It is logical
The pulsation of over cleaning flow quantity can improve the cleaning performance of ink gun 40.
Moreover, the liquid level of the ink 70 (Fig. 8) when the liquid level of the cleaning solution 71 in surge tank 30,50 is sprayed than ink is high.
Therefore, it is possible to the ink residue being effectively removed on the wall surface being attached near the liquid level of ink 70.
In the above-described embodiments, the liquid level in surge tank 30 is measured using level transducer 36 (Fig. 1).Also, according to this
At the time of measurement result is come at the time of determining unlatching open and close valve 35 shown in Fig. 3 and closing open and close valve 35 shown in Fig. 4.However,
Elapsed time infer liquid level after can also being started to work according to pump 22,23, with replace with level transducer 36 come
Measure liquid level.
For example, it is also possible to when have passed through the preset 1st from the time of ink 70 begins to flow into surge tank 30
Between at the time of carry out it is shown in Fig. 3 open open and close valve 35 control.Furthermore, it is possible to from the time of opening open and close valve 35 by
The control shown in Fig. 4 for closing open and close valve 35 is carried out at the time of preset 2 time.It is determined according to by the time
In the case of the open and close control moment of open and close valve 35, it is convenient to omit level transducer 36.
The liquid level of surge tank 50 can also be inferred according to elapsed time after 22,23 start-up operation of pump.Therefore, also may be used
To carry out the open and close control to open and close valve 55 according to elapsed time after 22,23 start-up operation of pump.
Then, the ink-jet apparatus based on another embodiment is illustrated with reference to figure 11.Hereinafter, pair with Fig. 1 shown in
