This routine printing ink discharger is to use the application examples at the ink jet recording device of the discharge of the long size of the horizontal expansion of the posting field of whole paper used for recording P 11.But the present invention is also applicable to the ink jet recording device of serial scan mode,, discharges the writing scan and the action of the paper used for recording of conveying ormal weight on the sub scanning direction that intersects with this main scanning direction of the main scanning direction of head repeatedly that is.
Fig. 2 is the summary pie graph of the ink supply system (liquid delivery system) in the printing ink discharger of Fig. 1.Printing ink in the print cartridge 13 that releasably is provided with are supplied with to discharging 11 by secondary jar 23, so that discharging the spout face (オ リ Off ィ ス face) that forms suitable printing ink on 11 the outlet.The 24th, be used for from the supply pump of print cartridge 13 to secondary jar 23 supply printing ink, the 25th, be used for from secondary jar 23 to discharging a force (forcing) pump of 11 supply printing ink.The 26th, at the valve that resets to return flow path described later when discharging the head pressurization, as to be used to close printing ink.Supply pump 24 also is used for do action described later, and the 27th, when carrying out this do action, be used to select the supply valve of ink path.Do action is the action that the printing ink of discharging when the reset processing of discharging 11 is utilized again, when carrying out this do action, uses the bucket 28 that resets of reset assembly 12.This bucket 28 that resets is arranged on the below of 11 the discharge face (the formation face after the discharge) of discharging, utilize circulating valve 29 switches from this bucket 28 that resets to secondary jar 23 ink path.
According to pattern described later, by the control of being correlated with of 100 pairs of supply pumps 24 of control part (control device), force (forcing) pump 25, the valve 26 that resets, supply valve 27 and circulating valve 29.
Below, just the pattern of the ink supply system in such printing ink discharger describes.
Ink supply system has four patterns such as logging mode, inking pattern, circulation pattern and pattern of pressure.Logging mode is to discharging a pattern of 11 supply printing ink when carrying out picture record, from secondary jar 23; The inking pattern is to secondary jar 23 pattern of supplying with printing ink from print cartridge 13.And circulation pattern is to make printing ink at secondary jar 23 with discharge a pattern that circulates between 11; Pattern of pressure is to the pattern of discharging 11 a forced feed printing ink from secondary jar 23.
When logging mode, by discharging printing ink from discharging 11, these printing ink of discharging in 11 reduce drops in it.And by discharging the capillarity in 11 the nozzle, the printing ink in secondary jar 23 is discharged 11 by the force (forcing) pump 25 and 26 pairs on the valve that resets respectively and is replenished.When the inking pattern, supply pump 24 actions are supplied with printing ink from print cartridge 13 in secondary jar 23.When circulation pattern, by force (forcing) pump 25 make printing ink secondary jar 23 and discharge 11 between circulation.That is, the printing ink in secondary jar 23 is transported to by force (forcing) pump 25 and discharges in 11, and the printing ink in this discharges 11 turn back in the secondary jar 23 by the valve 26 that resets.By the circulation of such printing ink, remove as described later discharge 11 or stream in bubble, can carry out appropriate record.When this circulation pattern,, pass circulating valve 29 by the action of supply pump 24 and turn back to secondary jar 23 from discharging the printing ink that an outlet of 11 is discharged to the bucket 28 that resets.Pattern of pressure as described later, is the pattern of carrying out in order to discharge bubble, tackify printing ink and the foreign matter etc. in 11 the nozzle.When this pattern of pressure, by closing the valve 26 that resets, driving force (forcing) pump 25, forcibly printing ink is transported to from secondary jar 23 and discharges 11, in the bucket 28 that resets, forcibly discharge printing ink from discharging an outlet of 11.
Fig. 3 is the front view that a configuration example of 11 is discharged in explanation, and Fig. 4 is the cutaway view along the IV-IV line of Fig. 3, and Fig. 5 is the expanded view of the V circle portion of Fig. 3.The discharge head of this example has 4 inches record width (length that is equivalent to nozzle rows).
In these figure, the base plate 31 of pottery system supports the heated substrates 32 that is formed by silicon.On heated substrates 32, form as a plurality of electrothermal transformationers (heater) of the exhaust energy producing component of printing ink and be used to form the stream wall of the printing ink stream of corresponding these electrothermal transformationers.By these electrothermal transformationers and printing ink stream, constitute a plurality of nozzle N that can discharge printing ink from outlet.And, on heated substrates 32, also be formed for surrounding the liquid chamber frame of the common liquid chamber 33 that is communicated with each nozzle N.At the sidewall of the nozzle N that forms like this with above the liquid chamber frame, engage and be useful on the top board 34 that forms common liquid chamber 33.Therefore, heated substrates 32 and top board 34 are bonded on the base plate 31 in mutual incorporate state laminated.With elargol (Silver ペ one ス ト) etc. the high adhesive of pyroconductivity carry out laminate adhesive.Utilize PCB (wiring board) 35 after two-sided tape will be installed to be supported on the rear (top among Fig. 4) of the heated substrates 32 on the base plate 31.Each exhaust energy producing component and PCB35 on the heated substrates 32 are by the wire bond 36 formation electrical connections of each wiring of correspondence.
Inking parts (liquid feeding parts) 37 be bonded on top board 34 above.These inking parts 37 are made of inking box (liquid feed cassette) 38 and inking box cover (liquid feed cassette cover) 39.The flow passage groove that on inking box 38, forms liquid chamber and be communicated with in advance with this liquid chamber.Inking box cover 39 forms the stream of tubulose as described later by blocking the top of inking box 38.This example is by the adhesive bond inking box 38 of thermmohardening type and inking box cover 39.Like this, by being formed on the stream in the inking parts 37, supply with printing ink to the access 34A that is formed on the top board 34.
And, first, second and the 3rd totally three filters 40,41,43 are set on inking box 38.The purpose of first filter 40 is foreign matters of removing in the printing ink, the purpose of second filter 41 is bubbles of removing in the main inking chamber (main liquid supply chamber) 42, and the purpose of the 3rd filter 43 is bubbles of removing in the first inking chamber (the first liquid supply chamber) 44.Each filter 40,41,43 forms by stainless steel fibre is woven webbed material with the interval of 8 μ m, is fixed on the liquid feed cassette 38 by the fusion gummed.The specific performance of each filter 40,41,43 as described later.
Fig. 6 is the stereogram at the main position of the discharge 11 in this example.This figure sees from inking box 38 sides to discharge a stereogram of 11, has omitted inking box cover 39 and screw etc. for convenience of explanation.
By secondary jar 23 printing ink of supplying with of printing ink discharger, at first by discharging first coupling opening 45 (ジ ョ ィ ン ト Open ロ) of 11, supplying with to the first inking chamber 44.Printing ink in this first inking chamber 44 is supplied with to main inking chamber 42 by first filter 40.Main inking chamber 42 by up and down the 42A of wall portion, 42B and about and four 42C of wall portion, 42D and 42E, the 42F of front and back form.In the 42A to 42F of these wall portions, the 42F of wall portion is formed on the inking box cover 39, and other wall portions all are formed on the inking box 38.Form on the main inking chamber 42 is arranged to be laminated in the first inking chamber 44, with these main inking chamber 42 adjacency.
The printing ink of supplying with in so main inking chamber 42 arrives nozzle N through the access 34A and the common liquid chamber 33 (with reference to Fig. 5) that are formed on the supply port 42G on the 42E of wall portion and be formed on the top board 34.And, supply to the printing ink of main inking chamber 42, be transported to the second inking chamber (the second liquid supply chamber) 46 by second filter 41, and, turn back to secondary jar 23 through second coupling opening 47.The second liquid supply chamber 46 is arranged to be laminated to form on the main inking chamber 42, with these main inking chamber 42 adjacency.
In the flowing of such printing ink,, must supply with printing ink to nozzle N in order to carry out high-speed record unobstructedly.That is, need reduce the design of the flow path resistance in the printing ink stream as far as possible.Therefore, to shown in Figure 5, the discharge in this example 11 is the connection first inking chamber 44, main inking chamber 42, common liquid chamber 33 and nozzle N directly as Fig. 3.And, first coupling opening 45, the first inking chamber 44 and nozzle N, the top of formation from Fig. 4 is towards the straight line stream of below.And in order to reduce a flow path resistance of discharging in 11, the sectional area that makes stream is with identical as the internal diameter of first coupling opening 45 of the inlet of discharge 11 or greater than this internal diameter.Constantly supply with printing ink thus.This example forms the sectional area more than or equal to φ 3 (diameter is 3mm) on overall flow paths.
And, in order not destroy the supply performance of printing ink, will become the filter formation large tracts of land of discharging a main cause that 11 interior ink pressure are lost.In this example, be equivalent to φ 20 (diameter is 20mm), the pressure loss minimum that this filter 40 is formed by the effective area that makes first filter 40.And, by with the parallel plane plane of the nozzle arrangement that row were positioned at of nozzle N on first filter 40 is set, can exempt from the maximization of the discharge that produces along with the large tracts of landization of this filter 40 11.After obtaining such effect, filter 40 need not parallel fully with the nozzle arrangement plane, can be almost parallel.Therefore, with filter 40 be arranged on the parallel plane plane of nozzle arrangement on, comprise filter 40 is arranged on the plane with nozzle arrangement plane almost parallel.
Because nozzle N is formed between heated substrates 32 and the top board 34, so extend with the above-below direction of mode in Fig. 4 and Fig. 5 along the junction surface of heated substrates 32 and top board 34 on the nozzle arrangement plane.First filter 40 be positioned at the parallel plane plane of this nozzle arrangement on, that is, and on the plane parallel with the paper among Fig. 3.
Greatest problem when on the other hand, adopting the large tracts of land filter as first filter 40 is to remove the bubble that is trapped in this filter upstream portion easily.Problem in this example is to remove the bubble that is trapped in easily in first supply chamber 44.In case bubble remains in this part, then this bubble hinders and supplies with printing ink, can not effectively utilize whole effective areas of filter 40.
Therefore, in this example, by the bypass flow path (バ ィ パ ス stream) 48 that is communicated with the first inking chamber 44 and the second inking chamber 46 is set, and the 3rd filter 43 is set in this bypass flow path 48 solves such problem.The 3rd filter 43 is designed to little area, so that remove the bubble that flows into printing ink from the first inking chamber 44.That is, improve printing ink from the flow velocity of the first inking chamber 44, remove bubble from this first inking chamber 44 by the 3rd filter 43 by the area that dwindles the 3rd filter 43.
But under the too small situation of the area that makes the 3rd filter 43, the flow resistance that flows through printing ink wherein increases, and has printing ink can not flow into the danger of the 3rd filter 43 sides fully, in this case, can not remove the bubble in the first inking chamber 44.On the other hand, under the excessive situation of the area that makes the 3rd filter 43, flow resistance in the 3rd filter 43 is less than the flow resistance in first filter 40, most of printing ink in the first inking chamber 44 flows into the 3rd filter 43 sides, and first filter, 40 sides that might should obtain supplying with can not obtain supplying with.In this example, supply with printing ink to main inking chamber 42 for bubble, the one side that can simultaneously remove the first inking chamber 44 expeditiously by first filter 40, the area that makes the 3rd filter 43 is φ 2 (diameter is 2mm).By changing the density of the 3rd filter 43, can improve flow velocity by the printing ink of the 3rd filter 43.
This routine printing ink discharger needs the heat release energy in order to discharge printing ink.That is, constitute the heat energy that produces by the electrothermal transformationer on the heated substrates 32 printing ink is bubbled, utilize this foaming energy to discharge printing ink from the below of nozzle to Fig. 5.Therefore, carry out in long-time continuous under the situation of operation of recording, heat energy savings in printing ink, the temperature of printing ink rises, being dissolved in gas in this printing ink has and accumulates in the danger of discharging in 11.If do not remove the bubble in this discharge 11, then printing ink can not carry out suitable discharge.In addition, it is not only specific for using the structure of electrothermal transformationer that the exhaust energy that is used to discharge printing ink produces mechanism, can be for example to use piezoelectric element etc. to discharge the arbitrary structures of printing ink yet.
As shown in Figure 4, in the discharge of this example 11,, can be stored in along with the bubble that operation of recording produces in the main inking chamber 42 by each nozzle N, common liquid chamber 33 and main inking chamber 42 directly are communicated with.And, by main inking chamber 42 is formed big capacity liquid chamber, can more bubble be stored into to a certain degree.And, by second filter 41 being set, can removing easily the bubble that is present in the main inking chamber 42.Promptly, make printing ink at secondary jar 23 with when discharging the circulation pattern of circulation between 11 by force (forcing) pump 25, owing to can improve flow velocity by the printing ink of second filter 41, therefore by this second filter 41, can easily remove the bubble in the main inking chamber 42.
Fig. 7 to Figure 10 be discharge 11 and secondary jar 23 between the ideograph of ink supply system, represent the flowing of printing ink in each inking state.
Fig. 7 is the ink flow figure when printing ink is filled in main inking chamber 42.
Printing ink in secondary jar 23 enters the first inking chamber 44 by the action of force (forcing) pump 25 from first coupling opening 45, passes first filter 40 then and flows in the main inking chamber 42.At this moment, the gas in the main inking chamber 42 is discharged from second coupling opening 47 owing to passing second filter 41 and the second inking chamber 46, therefore is full of printing ink in the main inking chamber 42.Fig. 7 represents the pattern of printing ink stream, and in the structure of the discharge of Fig. 3 to Fig. 6 11, the gases in the second inking chamber 46 are discharged by stream L1, L2 and L3.Promptly, gas in the second inking chamber 46 is by the stream L2 that is formed on stream L1 in the inking box 38, formed by slot part and the inking box cover 39 of inking box 38 and be formed on the interior stream L3 of inking box 38 from 47 discharges of second coupling opening.
At this,, preferably will form large tracts of land as first filter 40 of the main cause of discharging the pressure loss in 11 in order to fill printing ink unobstructedly to main inking chamber 42.But, on the other hand, forming large tracts of land by making first filter 40, the flow velocity of the printing ink of its unit are will reduce, and the bubble that therefore is present in the first inking chamber 44 is not easy by first filter 40.Its result, bubble accumulate in first filter 40 upstream side, the danger that hinders ink flow is arranged.Therefore, as mentioned above, form the bypass flow path 48 that connects between the first inking chamber 44 and the second inking chamber 46, the 3rd filter 43 is set in this stream 48.By like this, the bubbles in the first inking chamber 44 can be discharged from second coupling opening 47 through the 3rd filter 43 and the second inking chamber 46.That is,, can remove bubble from the first inking chamber 44 by in the part of the 3rd filter 43, improving the flow velocity of printing ink.Therefore, can fill printing ink by the whole surface of first filter 40 unobstructedly.
Fig. 7 is the stream ideograph of printing ink, in the structure of the discharge of Fig. 3 to Fig. 6 11, is forming the stream 44 that is communicated with between first coupling opening 45 and the first inking chamber 44 on the inking box 38.And, form stream L5 by the slot part and the inking box cover 39 of inking box 38, on inking box 38, form the stream L6 that is communicated with stream L5 and above-mentioned stream L2.Therefore, the bypass flow path among Fig. 7, promptly be communicated with stream between the first and second inking chambers 44,46, form by stream L4, L5, L6, L2 and L1.In a word, bypass flow path 48 can be discharged by the 3rd filter 43 gas in the first inking chamber 44 and be got final product from second coupling opening 47.And, in the structure of the discharge of Fig. 3 to Fig. 6 11, mark off space in the inking box 38 by utilizing first and second filters 40,41, can form first, second inking chamber 44,46 and main inking chamber 42.
Fig. 8 represents to be used to discharge the ink flow when being present in the pressurization of discharging bubble, tackify printing ink and foreign matter etc. in 11 the nozzle and resetting.The action of the ink supply system when this pressurization resets is corresponding with above-mentioned pattern of pressure.
As mentioned above, this routine printing ink discharger is in order to discharge the printing ink energy that need generate heat.Therefore, when writing down, because this heat energy is put aside in printing ink, the temperature of printing ink rises, so the danger of gas accumulation in nozzle that is dissolved in the printing ink is arranged on long-time continuous ground.If do not remove this bubble, then printing ink can not carry out suitable discharge.Therefore, need suitably remove the interior bubble of nozzle N.Printing ink in secondary jar 23 enters in the first inking chamber 44 from first coupling opening 45 by the action of force (forcing) pump 25, passes first filter 40 then and flows in the main inking chamber 42.When this pressurization resetted, owing to closed the valve 26 that resets, therefore the printing ink of supplying with to main inking chamber 42 was forcibly flowed to nozzle N side from common liquid chamber 33.Then, bubble, tackify printing ink and the foreign matter etc. of this printing ink in nozzle N are forcibly discharged from the outlet of discharging a nozzle N of 11.Fig. 8 is the ideograph of printing ink stream, in the structure of the discharge of Fig. 3 to Fig. 6 11, printing ink in the main inking chamber 42 is forcibly discharged from the outlet of nozzle N by being formed on the stream L7 on the inking box 38, the access 34A and the common liquid chamber 33 of top board 34.
Ink flow during Fig. 9 represents to write down.The action of the ink supply system in this record is corresponding with above-mentioned logging mode.
Discharge droplets of ink I by the nozzle N from record, discharge 11 an interior printing ink and reduce drops in it.And by the capillarity in the nozzle N, the printing ink in secondary jar 23 engages by force (forcing) pump 25 and first and opens 45 and replenish to discharging 11.At this moment, also open the valve 26 that resets, printing ink flows into from second coupling opening 47 and discharges in 11.In record, especially, need supply with printing ink to nozzle N in order to keep high-speed record unobstructedly, need to reduce the pressure loss in first filter 40.Therefore, similarly get rid of the bubble in the first inking chamber 44 during with filling printing ink, can effectively utilize the whole surface of first filter 40 and supply with printing ink.That is, by being arranged on the 3rd filter 43 on the bypass flow path 48 of leading to the second inking chamber 46, one side is discharged bubble, in the first inking chamber 44 and 42 is supplied with printing ink towards main inking chamber from the first inking chamber 44.Therefore, do not supply with printing ink even in high-speed record, can not incur loss through delay to nozzle N yet.Fig. 9 also is the stream ideograph of printing ink, in the structure of the discharge of Fig. 3 to Fig. 6 11, printing ink in the main inking chamber 42 by be formed on the stream L7 on the inking box 38, the access 34A and the common liquid chamber 33 of top board 34 supplied with in nozzle N, discharge as droplets of ink I from the outlet of this nozzle N then.
Figure 10 is illustrated in and makes printing ink secondary jar 23 and ink flow when discharging the cycle reset of circulation between 11.By this cycle reset, can remove in record, be created in discharge 11 and stream in bubble, can keep suitable record.The circulation pattern that the action of the ink supply system during this cycle reset is corresponding above-mentioned.
When carrying out cycle reset, the action that pair jar 23 interior printing ink pass through force (forcing) pump 25 flows into the first inking chamber 44 from first coupling opening 45, and passes in the main inking of first filter, the 40 inflows chamber 42.Meanwhile, accumulating in bubbles in the main inking chamber 42 passes second filter 41 and discharges to second coupling opening, 47 sides.The discharge of this example 11 is owing to form big capacity liquid chamber with main inking chamber 42, so the bubble that produces can to a certain extent long-time continuous be write down the time is stored in the main inking chamber 42.Accumulate in the bubble in this main inking chamber 42, can easily remove by second filter 41 by this cycle reset action.
Second embodiment
Figure 11 and Figure 12 are the key diagrams of second embodiment of the present invention.The part identical with above-mentioned embodiment used same symbol and omitted explanation in these figure.
Identical with above-mentioned embodiment, main inking chamber (main liquid give chamber) 42 is formed by the 42A to 42F of wall portion, and the supply port 43G that is communicated with the 42B of wall portion and the common liquid chamber 33 of downside is formed on the left and right directions among Figure 11 abreast.
In the present embodiment, form the inclined plane that tilts with angle θ 1 with respect to horizontal direction on the 42A of wall portion of upside, this inclined plane tilts towards second filter, 41 side direction from first filter, 40 sides.That is, on the 42A of wall portion, form and the gravity direction inclined plane of orthogonal not.By on the 42A of wall portion of upside, forming the inclined plane like this, can make the bubble in the main inking chamber 42 focus on second filter, 41 sides.That is, the bubble by buoyancy force is moved along the 42A of wall portion of upside.By angle θ 1 is set at more than or equal to 4 °, can confirm moving of bubble.Tilt by the 42A of wall portion that makes upside like this, can further improve the elimination efficiency of discharging the bubble in 11, also can shorten and implement the needed time of circulation pattern.1 to 4 ° of angle θ is big more, and the effect that bubble is moved is strong more.But, so be preferably about 20 ° during practical application because angle θ 1 is big more, to discharge a height of 11 also high more.
In this example, the 42A of wall portion of upside and nozzle arrangement plane orthogonal, the inclination face of angulation θ 1 on the 42A of this wall portion.But the 42A of wall portion so long as have is used to facial the getting final product of inclination that the bubbles in the main inking chamber 42 are moved.
The 3rd embodiment
Figure 13 is the key diagram of the 3rd embodiment of the present invention.The part identical with above-mentioned embodiment used same symbol and omitted explanation in Figure 13.
In the present embodiment, the right side in Figure 13 of the 42A of wall portion of upside forms part (inclined plane) 42A-1 that relative horizontal direction tilts with angle θ 1, and this part 42A-1 tilts towards second filter, 41 side direction from first filter, 40 sides.And the part in the left side in Figure 13 of the 42A of wall portion of upside forms part (inclined plane) 42A-2 that relative horizontal direction tilts with angle θ 2, and this part 42A-2 tilts towards first filter, 40 side direction from second filter, 41 sides.By apex (summit) 42A-3 of these parts 42A-1,42A-2 formation between first filter 40 and second filter 41.
Under the residual situation that small bubble arranged, this bubble might hinder in operation of recording and supply with printing ink from second filter 41 near second filter 41 in main inking chamber 42.In this example, form the part 42A-2 of angle θ 2 upwards by on the 42A of wall portion of upside, forming towards first filter, 40 sides, bubble can be accumulated on the apex 42A-3 of the 42A of wall portion of the position of leaving second filter 41 from second filter, 41 sides.Its result, elimination efficiency, the one side that can simultaneously improve bubble make near do not hold the record inking performance in moving of the bubbles that remain in second filter 41 with not hindering inking.
