Embodiment 1

The front view of Fig. 1 summary during from the printer of this embodiment of forward observation for expression.As shown in Figure 1, from the beginning 1 to the printing ink of paper 3 injections as liquid, and said paper 3 is as the medium that is supported and be transferred from the below by platen 2.Paper 3 is transferred forward, and from the beginning printing ink 1 sprayed towards the below, thereby on paper 3, form image or literal.1 is the line head greater than the width on the left and right directions of paper 3.Omitted the mechanism that paper 3 is carried.

On printer, be mounted with four main jars 6 that store printing ink with the mode that can change.In main jar 6, black Bk, magenta M, blue-green C, these four kinds of printing ink of yellow Y are incorporated in respectively in different main jar 6.Though be provided with four kinds of printing ink in this application, both can be provided with more than five kinds, also can be provided with below three kinds.In addition, the printing ink of same color also can be provided with more than two.In addition, main jar 6 and secondary jar 10 are set up on the equal height in vertical direction along left and right directions.That is, be set on the direction that the throughput direction with paper 3 intersects.

On each main jar 6, be connected with an end that flows into runner 8.The other end that flows into runner 8 is connected to secondary jar 10.The printing ink of every kind of color from main jar of 6 sides via flowing into runner 8 to secondary jar 10 side flow, supply.In Fig. 1, expression flows into the single line of runner 8 and representes pipe.In addition, the arrow of the other end of inflow runner 8 is represented the flow direction of printing ink.

Also be connected with an end that flows out runner 20 on secondary jar 10.The other end that flows out runner 20 is connected to 1.Printing ink 1 flows from secondary jar 10 via flowing out runner 20 headward.That is, secondary jar 10,1 and flow out runner 20 and be communicated with.In addition, 1 and main jar 6 between secondary jar 10 of configuration.In Fig. 1, the single line of expression outflow runner 20 is represented pipe.In addition, the arrow labeled of the other end of outflow runner 20 is represented the flow direction of printing ink.Flow out valve 22 disposing of outflow runner 20 midway.Flow out valve 22 through pipe is pushed, thereby forbid, through pipe not being pushed, thereby allow flowing from secondary jar 10 printing ink from the flowing of secondary jar 10 printing ink.Flowing out valve 22 also can push four pipes simultaneously.Omitted the mechanism that pipe is pushed.

1 also is connected through guiding in channel 21 with secondary jar 10.Dispose pump 25 midway at guiding in channel 21.Through this pump 25, from the beginning printing ink 1 flowed towards secondary jar 10.In Fig. 1, the single line of expression guiding in channel 21 is represented pipe.In addition, the arrow labeled of the end of guiding in channel 21 is represented the flow direction of printing ink.As an example, pump 25 has adopted on one side pipe has been pushed the peristaltic pump of rotation on one side.Peristaltic pump pushes rotation on one side to four pipes on one side simultaneously.Also can adopt membrane pump as another example.

In flowing out runner 20, can make the atmosphere passage 30 that flows out runner 20 and atmosphere in flowing out to be connected with between valve 22 and 1.One end of atmosphere passage 30 is connected the other end and atmosphere with outflow runner 20.Atmosphere passage 30 have atmos-valve 31 midway, said atmos-valve 31 is allowed or is forbidden flowing out being communicated with of runner 20 and atmosphere.In Fig. 1, the single line of expression atmosphere passage 30 is represented pipe.Atmos-valve 31 is through pushing pipe, thereby forbids and being communicated with of atmosphere, and through pipe not being pushed, thereby allows and being communicated with of atmosphere.Flowing out valve 22 and atmos-valve 31 can be through the identical parts of use, and simultaneously pipe is pushed, thereby allows respectively or forbid.

As shown in Figure 1, secondary jar 10 be configured in position that 1 compares by the below on.Like hereinafter narration, secondary jar 10 and atmosphere.Since with 1 be communicated with secondary jar 10 be positioned at the position of comparing by the below with 1, therefore the printing ink in 1 becomes less than atmospheric negative pressure state.Be negative pressure in 1 through making, thereby can control the droplets of ink of injection exactly.When printing ink is consumed in 1, printing ink will 1 flow from secondary jar 10 via flowing out runner 20 headward.At this moment, flow out the pipe that valve 22 not convection current go out runner 20 and push, thereby allow flowing from secondary jar 10 printing ink.In addition, the pipe of 31 pairs of atmosphere passages 30 of atmos-valve pushes, thereby forbids flowing out runner 20 and atmosphere.Because printing ink 1 flows from secondary jar 10 naturally headward, therefore do not possess the pump that is used to make ink flow flowing out on the runner 20.

In addition, main jar 6 is configured on the position of comparing by the top with secondary jar 10.Printing ink in main jar 6 flows to secondary jar 10 via flowing into runner 8 through the pressure that is caused by head difference.Because printing ink flows because of head pressure, therefore do not have to main jar 6 pressing mechanism and what flow into runner 8 and do not possess pump midway.In secondary jar 10, possesses the supply control valve 23 that back literary composition narration is arranged.Supply with the amount of control valve 23 according to the printing ink in secondary jar 10, thus allow or forbid printing ink from main jar 6 to secondary jar 10 flow.

Pump 25 is driven when from the beginning discharging printing ink in 1.For example, suppose to be in from printer and take off a situation of 1, or prevent for a long time not from the beginning 1 ink jet, thereby printing ink is in the situation of 1 inner drying or deposition.At this moment; The pipe that goes out runner 20 through 22 convection current of outflow valve pushes; Thereby forbid that printing ink flows from secondary jar 10, and atmos-valve 31 is not pushed the pipe of atmosphere passage 30, thereby under the state that flows out runner 20 and atmosphere, pump 25 is driven.So; Owing to introduce air from the top of atmosphere passage 30; Therefore through to circulation passage 20 and atmosphere passage 30 between connecting portion compare in the outflow runner 20 of something or somebody to fall back on side more, supply atmosphere in 1, in the guiding in channel 21; Thereby printing ink and air are replaced, and then printing ink is discharged to secondary jar 10.Flowing into runner 8, guiding in channel 21 and flowing out in the runner 20, only on guiding in channel 21, possesses pump 25.

Fig. 2, Fig. 3 represent about main jar 6, secondary jar 10 of a kind of color, 1 and each runner.As shown in Figure 1, every kind of color is furnished with master's jar 6, secondary jar 10, inflow runner 8, outflow runner 20, guiding in channel 21 and 30, four kinds of colors of atmosphere passage respectively and is provided with a stature 1 altogether.But, 1 within it portion be nozzle and the runner that every kind of color is provided with ink jet.In addition, will with main jar 6, flow into runner 8, secondary jar 10 and flow out runner 20 and be called feed unit as one group unit, said feed unit be the set of the parts of 1 supply printing ink headward.Have a plurality of (four) feed unit in this application, each feed unit is connected in 1.

Main jar 6, secondary jar 10 shape is all identical for shades of colour.Employed pipe both can be made as equal length based on shades of colour in each runner, also can change length based on the position component that is connected.Preferably forms for secondary jar 10 so that the printing ink that can Visual Confirmation stored and the parts of inside by transparent component.

In Fig. 2, main jar 6 ink receptive body 7 with the flexibility that is used to take in printing ink.On main jar 6, be connected with an end that flows into runner 8.Has the valve 9 of inflow midway what flow into runner 8.Main jar 6 o'clock are being installed, and the pipe that runner 8 is gone in the 9 not convection current of inflow valve pushes, thereby allows the mobile of next autonomous jar 6 printing ink.Be not mounted main jar 6 o'clock, flow into the pipe that valve 9 goes into runner 8 through convection current and push, thereby forbid flowing into moving of printing ink in the runner 8.The other end that flows into runner 8 is connected in secondary jar 10 inflow connecting portion 11.Thus, make master's jar 6, secondary jar 10 and 8 connections of inflow runner.

Secondary jar 10 is the roughly rectangular shape of hollow, and have upside be opening peristome.Peristome partes tegmentalis 26 covers.Cap 26 is a writing board shape, and its one side side has groove 27, and the another side side has the hole of running through from groove 27.The groove 27 of cap 26 is capped through sealing 28.Sealing 28 has air connectivity hole 29.Secondary jar of 10 hole, groove 27 and air connectivity hole 29 via cap 26 and and atmosphere.

Have for secondary jar 10 and be connected in the inflow connecting portion 11 that flows into runner 8.Flowing into connecting portion 11 does, the projection outstanding from the inside of pair jar 10 towards the outside, and it has the inside and outside through hole that is communicated with secondary jar 10.Printing ink is positioned at secondary jar 10 private side from this through hole inflow entrance 12 flows into to secondary jar 10 inside.The printing ink that flows into is stored in secondary jar 10.Main jar 6 is connected by flowing into runner 8 with inflow entrance 12.

Secondary jar of 10 internal configurations float part 35 is arranged, said float part 35 is can being that the mode that rotate at the center is supported with fulcrum 36.Float part 35 is the parts floating with respect to printing ink.

In secondary jar 10, have the control valve 23 of supply, this supplys control valve 23 is that rotate at the center with the fulcrum in secondary jar 10.Supply with the sealing that has ring-type on the control valve 23, when supplying with control valve 23 through force application spring 24 and by the application of force, sealing will be close to inflow entrance 12 around.In this way, forbidden that printing ink flows in secondary jar 10 from inflow entrance 12.Compare more and lean on the position of top owing to be positioned at for main jar 6, so printing ink flows from main jar 6 to secondary jar 10 because of head difference naturally with secondary jar 10.If the flowing of printing ink to secondary jar 10 continues always, then secondary jar 10 interior will being full of by printing ink, thus printing ink will overflow from air connectivity hole 29.Through stoping printing ink mobile in secondary jar 10, thereby prevented above-mentioned situation by supplying with control valve 23.

And when printing ink is consumed 1, thereby the printing ink that stores in secondary jar 10 reduces, and the liquid level of printing ink is when descending, and float part 35 will be that rotate downwards at the center with fulcrum 36.And, as shown in Figure 3, when printing ink reduces, float part 35 will with the bar portion butt of supplying with control valve 23, and overcome the application of force of force application spring 24, supply with control valve 23 and rotate and make.Rotate when supplying with control valve 23 so that sealing remove to around the inflow entrance 12 be close to state the time, printing ink will flow into from inflow entrance 12.

In this way,, and the position of float part 35 is changed, and according to its position, allow or forbid printing ink passing through from inflow entrance 12 by supplying with control valve 23 according to the amount of the printing ink in secondary jar 10 and the height of liquid level.That is, supplying with 23 pairs of printing ink of control valve controls from main jar 6 inflow to secondary jar 10.In addition, through the action of supplying with control valve 23 printing ink being flowed into is also stored in secondary jar 10.

Have for secondary jar 10 and be connected with the outflow connecting portion 13 that flows out runner 20.Flowing out connecting portion 13 does, from the projection that give prominence to the outside inside of pair jar 10, it has the inside and outside through hole that is communicated with secondary jar 10.Printing ink is positioned at secondary jar 10 private side from this through hole flow export 14 flows out.

Flowing out runner 20 is connected with 1 supply port 1b.Thus, secondary jar 10 with 1 quilt is connected via flowing out runner 20.Printing ink goes out towards an effluent from secondary jar 10 flow export 14.1 also is connected through flowing out runner 20 with flow export 14.Has the valve 22 of outflow midway what flow out runner 20.

Flowing out runner 20 is connected with atmosphere passage 30 flowing out between valve 22 and 1.In other words, in flowing out runner 20, with the connecting portion of atmosphere passage 30 and flow export 14 between dispose outflow valve 22.In Fig. 2, flow out runner 20 and become one with atmosphere passage 30.But also can use joint to wait connects.Atmosphere passage 30 has gas permeation portion 32 at the opposition side that flows out runner 20.Gas permeation portion 32 does, have a plurality of gases can through but the parts in the small hole that liquid can't pass through.Thus, prevented the situation that printing ink spills from gas permeation portion 32.In Fig. 2, though gas permeation portion 32 sides of atmosphere passage 30 are not limited thereto towards the below, it all can towards any direction in addition.In addition, also gas permeation portion 32 can be set.At this moment, because the top of pipe is open, therefore the top of preferred pipe is towards the top.Make printing ink be difficult for leaking thus.

1 sprays the printing ink of supplying with from supply port 1b from nozzle 1a.1 has outlet 1c.Be connected with guiding in channel 21 on the outlet 1c.

Has the importing connecting portion 15 that is connected with guiding in channel 21 for secondary jar 10.Importing connecting portion 15 does, the projection outstanding from the inside of pair jar 10 towards the outside, and it has the inside and outside through hole that is communicated with secondary jar 10.Printing ink is positioned at secondary jar 10 private side from this through hole introducing port 16 is imported into.1 is connected through guiding in channel 21 with introducing port 16.

Has pump 25 midway at guiding in channel 21.Thereby through pump 25 is driven make printing ink in guiding in channel 21 from the beginning 1 side flow towards secondary jar of 10 inside.

Here, place the state that flows of allowing, atmos-valve 31 is placed the state that is communicated with of forbidding flowing out runner 20 and atmosphere, and pump 25 is driven from secondary jar 10 printing ink with flowing out valve 22.At this moment because printing ink flows through secondary jar 10 successively, flows out runner 20,1, guiding in channel 21, secondary jar 10, thereby formed circulation.Thus, thereby the composition deposition that has prevented to store the printing ink in pair jar 10 produces the situation of the concentration difference of printing ink, thereby has prevented that perhaps the 1 interior printing ink from evaporating the situation of the viscosity increase of printing ink.

In addition, place the state of forbidding from the printing ink of pair jar 10 that flows, atmos-valve 31 is placed the state that allows to flow out runner 20 and atmosphere, and pump 25 is driven flowing out valve 22.At this moment, the gas permeation portion 32 from atmosphere passage 30 introduces atmosphere.Therefore, flow out that the connecting portion with atmosphere passage 30 in the runner 20 plays the printing ink in the printing ink in the outflow runner 20 till 1,1, the printing ink in the guiding in channel 21 will be replaced with the atmosphere that is introduced into, thereby printing ink is discharged to secondary jar 10.In this application, " discharging printing ink to secondary jar 10 " is meant, printing ink by the state of air displacement, be that ink flow is to the state that exhausts.

As shown in Figure 2, in secondary jar 10, store under the state of printing ink, have in the secondary jar 10 as the float part 35 and the supply control valve 23 that constitute secondary jar parts, and in the part except that printing ink, have spatial portion 19.

When pump 25 is driven, thereby when discharging printing ink for secondary jar 10, the volume of spatial portion 19 is greater than the volume of the printing ink that is discharged from.Thus, discharge printing ink, also the situation that printing ink spills from air connectivity hole 29 can not occur even when beginning pump 25 driven, in secondary jar 10, store under the state of liquid to secondary jar 10.

In addition, when pump 25 is driven, and when discharging printing ink for secondary jar 10, if the printing ink in the guiding in channel 21 are all discharged, then after air will be mobile in secondary jar 10.Because the air that flows in secondary jar 10 flows out from air connectivity hole 29, therefore can not store in secondary jar 10.

In secondary jar 10, do not have the wall outstanding etc. from the bottom.Be not set at through this wall secondary jar 10 inside is separated.

Here, air connectivity hole 29 is communicated with via groove 27 with in secondary jar 10.Through groove 27 is set at wide 1 to 2mm and the degree of depth be 1 to 2mm than sulculus, thereby in the printing ink evaporation that prevents to store in secondary jar 10, make secondary jar 10 interior and atmosphere.Though the state during not shown shape of observing groove 27 from the top, its shape both can be made as linearity, made the elongated meander-like of distance thereby also can be made as bending.

In addition, when in secondary jar 10, discharging air, for example in Fig. 2, because introducing port 16 is positioned at the below of liquid level, so air will pass through from the inside of printing ink, occur the situation of generation bubble thus sometimes.Therefore, in introducing port 16, inflow entrance 12, flow export 14, with introducing port 16 be configured in the position of the top, promptly on the highest in vertical direction position.In two position relations, introducing port 16 is positioned at the position that is higher than introducing port 12 in vertical direction, and introducing port 16 is positioned at the position that is higher than flow export 14 in vertical direction.Thus, even in secondary jar 10, discharge air,, thereby can reduce the possibility of formation bubble also owing to shortened the distance that air passes through in printing ink.

In addition, though printing ink flows into from inflow entrance 12, the possibility that air flows into is lower.Therefore, also no problem even inflow entrance 12 is positioned at the position that is lower than introducing port 16 in vertical direction.In addition, be preferably, the position of flow export 14 is positioned at position minimum on the vertical direction in flow export 14, introducing port 16 and inflow entrance 12.Through making flow export 14 minimum, thereby be easy to farthest consume the printing ink in secondary jar 10.

In Fig. 2, Fig. 3, flow export 14, introducing port 16 and inflow entrance 12 all are set on secondary jar 10 the side of main part 18.But, be not limited thereto, only need to guarantee the described height relationships of preamble, then also can be arranged on bottom surface side.

In Fig. 2, in 1 downside, with the mode of surrounding nozzle 1a dispose can with a lid of 1 butt 4.Lid 41 during not to paper 3 ink jets with 1 butt, thereby prevent the phenomenon of printing ink from nozzle 1a evaporation.

As previously discussed, in this application, every kind of color has respectively: master's jar 6 as shown in Figure 2, inflow runner 8, secondary jar 10, outflow runner 20, guiding in channel 21.Here, when will flow into runner 8 for every kind of color, flow out runner 20, when guiding in channel 21 is set at a pipe, line as shown in fig. 1 is such, form situation about mixing complicatedly.Can think, for example the time can occur mistaken and pipe is inserted in the situation on different secondary jar 10 in assembling.All the time, for main jar 6 of not making that the user changes misplug into, and be pasted with the label that identifies color etc.But the pipe of secondary jar 10 and each runner is not taked this measure.

Therefore, in this application, with pair jars 10, flow into runner 8, flow out runner 20 and guiding in channel 21 forms, flow with portion within it or the color of ink that stores is the color of similar color.That is, pair jar 10, inflow runner 8, outflow runner 20 and guiding in channel 21 are set at the parts of black, magenta, blue-green, yellow four kinds of colors.But secondary jar 10 is formed by harder resin, and the rubber or the elastomer of managing by flexibility form.These parts and color of ink are unified into comparatively difficulty of identical color.In this application, the color of similar color is meant, when assembling, can be identified as the color of same color through Visual Confirmation.For example, even secondary jar 10 of the magenta that flows is red with pipe, but, therefore can be identified as similar color owing to be the color approaching with magenta.

Above-mentioned parts also can adopt and can be identified as and other color various colors through Visual Confirmation.Black, magenta, blue-green, yellow printing ink have been used in this application.According to resin or rubber etc., exist these colors to be difficult for adhering to or being difficult for the situation of identification sometimes.Therefore, also can not adopt with printing ink is the color of similar color, and adopts colourless or white.Originally when assembling, the printing ink of in secondary jar 10 and pipe, not packing into.Therefore, need not to make the solid colour of color of ink and secondary jar 10 and pipe.In same feed unit, only need secondary jar 10 to be similar color with the color of each pipe, can be connected to each other according to similar color.Between different feed units, only need to judge to get final product with the different of other feed units.

In addition, the length of pipe also becomes the key element of discerning.For example, on the long runner of the length between main jar 6 and secondary jar 10, can't connect short pipe.Therefore, carry out paintedly, and, can discern and connect as long as only on secondary jar 10, be attached with color even runner 8 is gone in not convection current.In this application, only needing on secondary jar 10, to be attached with color at least gets final product.And secondary jar 10 has cap 26 and main part 18.At this moment, both can on the both sides of cap 26 and main part 18, adhere to color, also can adhere to color on a certain side.If on cap 26, be attached with color, then from above can discern when observing.If on main part 18, be attached with color, then flow into connecting portion 11, flow out connecting portion 13, import connecting portion skilful last time and can discern in that pipe is connected.

In addition, as shown in Figure 1, from the secondary jar 10 outflow runner 20 till 1, the length of its pipe is according to color and difference.Therefore, flowing out runner 20 also can non-cohesive color.But, being the color of similar color if on outflow runner 20, adhere to secondary jar 10, then can under the condition of not observing length, connect.Guiding in channel 21 is same situation, and guiding in channel 21 both can adhere to secondary jar 10 and is the color of similar color, also can non-cohesive color.In addition, though not shown, when outflow runner 20 has carried out cutting apart via attaching parts halfway, be preferably, attaching parts are similar color with flowing out runner 20 also.

In addition; Even the length of pipe is identical, but owing on main jar 6, have the sign that every kind of color is discerned usually, even therefore only on secondary jar 10, adhere to color; And on inflow runner 8, do not adhere to color, also can the main jar 6 of similar color be connected with secondary jar 10.

In addition, the utility model is not limited to above-mentioned embodiment, also can be to various changes or the improvement etc. in addition of above-mentioned embodiment.Below narrate changing example.

Change example 1

Fig. 4 is the front view of example 1 related printer for a change.

Change example 1 and be secondary jar 10 height with the difference of embodiment 1.Because in addition changing example 1 be identical structure with embodiment 1, so only different points is described, and the explanation of omission repetition.

In this change example 1, four secondary jar 10 height in vertical direction is different.As shown in Figure 4, black is minimum, and magenta is identical height with blue-green, and yellow is the highest.Of preamble and since 1 with secondary jar 10 head difference, become negative pressure thereby make in 1.In addition, through from the beginning 1 spraying and consume printing ink, thereby printing ink 1 is flowed headward from secondary jar 10.When in printing ink is flowing out runner 20, flowing, flow passage resistance force of waterproof (dynamic pressure) will be according to the length of outflow runner 20 and difference.The longer then flow passage resistance force of waterproof of length that flows out runner 20 increases more.When flow passage resistance force of waterproof increases, printing ink become be difficult in flowing out runner 20 mobile, thereby can't control injection exactly from 1 printing ink.In Fig. 4, the distance of the outflow runner 20 till 1 is the longest to the end from secondary jar 10 of yellow, below is followed successively by blue-green, magenta and black by the length order.

In this change routine 1, the long secondary jar 10 of length that flows out runner 20 is configured in, and the secondary jar 10 short with flowing out runner 20 compared higher position.When adopting this mode,, increased negative pressure through reducing 1 with the head difference of secondary jar 10, thereby made printing ink be easier to flow though the size of flow passage resistance force of waterproof does not change.

In Fig. 4, make the height of black, magenta and blue-green, yellow three kinds different.But, both can change all height of secondary jar 10 of four kinds, also can for example change height according to black and magenta, blue-green and yellow these two kinds.
