Description
Technical field
The present invention relates to clean the method and the ink jet recording device of ink gun.The present invention is specifically related to be used for effectively to remove the ink residue on the surface that is formed with the inkjet mouth of ink gun (below be also referred to as record head or abbreviate head as) attached thereto (below be also referred to as jeting surface) etc. to clean this surperficial technology.
Background technology
Cleaning (cleaning) technology that is used for ink jet print head is an important factors of ink jet recording method, because this method is wherein to adopt liquid ink input image data to be converted to the system of output image as media.Subject matter in the needs cleaning has briefly been described below.
Ink jet print head directly is ejected into recording medium by fine nozzle (unless otherwise, these be called as jet, the fluid passage that is communicated with it jointly and be used to produce be used for the element of energy of ink-jet) with ink.Therefore, the ink that is ejected impacts on recording medium and bounce-back, and except when the ink-jet in record the related main ink, tiny ink droplet (adjunct) is injected in the atmosphere and drift therein in some cases.Then, these ink droplets become ink mist, and in some cases, are attached to around the inkjet mouth of record head.In addition, the dust that drifts about in air is attached on it sometimes.Subsequently, the main ink droplet that is ejected can be attracted by these attachment materials, makes inkjet direction skew thus, has hindered in some cases promptly that main ink droplet is straight to advance.
As the clean technologies that are used to address this problem, adopt the device be called as wiper to remove attachment material in ink jet recording device.This device with predetermined timing by by the elastomeric material jeting surface of Wiping member (wiper) the wiping record head made of rubber for example.
Simultaneously, the packing density of the material that writes down in order to improve, resistance to water, light resistance etc. have been used to comprise the ink (pigmented inks) of pigment component as colorant recently in many cases.By being dispersed in, colorant makes pigmented inks in the water, and by on surface of pigments, introducing dispersant or functional group, solid-state thereby described colorant is initially.Therefore, compare from the dry stickum of the dye-based ink that on molecular level, dissolves, by making the water evaporates that is arranged in the ink on the jeting surface and the more badly damaged jeting surface of dry matter of the dry paint ink that forms with colorant wherein.Also recognize such feature, the macromolecular compound that promptly is used for pigment is dispersed in the solvent is adsorbed on the jeting surface easily.Even reaction liquid is being joined in the ink so that in the ink except pigmented inks, also this problem can occur in the situation of the viscosity of control ink, thereby is improving light resistance and caused in ink, occurring macromolecular compound in addition.
In order to address these problems, in patent documentation 1 and 2, disclosed by with the ink gun of non-volatile solvents with liquid be applied on the jeting surface with the wearing and tearing that reduce wiper and in the wiping record head dissolving be accumulated in the technology that ink residue on the record head removes accumulated substance.And, by forming on the record head on ink gun prevents that with fluid film impurity is attached to record head, and improve the wiping convenience by these.Adopt the wherein employed ink gun structure of liquid storage in printer main body in these wipings.
In patent documentation 3, disclosed and after the ink gun that will be made of non-volatile solvents is applied on the wiper with liquid, on the record head jeting surface, carried out wiping operation.
In addition, in patent documentation 4, disclosed and to have dissolved liquid and be injected on the jeting surface, and used wiper to remove thus attached to the insoluble matter on the jeting surface.
In addition, in patent documentation 5, disclosed by will the ink residue on record head being dissolved in the non-volatile ink solvent that remains on the wiper and carried out wiping operation.
The inventor is applied on the jeting surface non-volatile solvent to check the effect of this cleaning course by the method disclosed in the patent documentation in the above.Find then that some composition materials of record head or some inks cause and fully to carry out by making the dissolving of ink residue remove the accumulation material or jeting surface is carried out the target cleaning, and new problem occurs.More particularly, find that the macromolecular compound component in the ink residue is dissolved with liquid by ink gun, but after the macromolecular compound of dissolving more equably on the surface attached to record head, thereby cause record head intrinsic surface characteristic change.In other words, this is because the film that is made of macromolecular compound is formed on the whole jeting surface, and thus macromolecular compound Characteristics Control the surface characteristic of record head.In general, the performance of the jeting surface of record head is by the form decision (whether comprising repellency or hydrophily etc.) that is applicable to employed ink, and therefore surface property changes inkjet performance self variation that causes record head.
In other words, can dissolve the shortcoming that ink residue on the jeting surface suppresses the ink residue build-up with liquid by ink gun is provided.But, can not fully remove wherein by ink gun and stay state on the jeting surface with the ink residue of liquid dissolving.In this state, can not keep the desired surface property of jeting surface.

The specific embodiment
The present invention is described in detail with reference to these accompanying drawings below.
(basic design of the present invention)
Illustrate that at first the performance of wiping ink residue changes with the relation between the surface tension of liquid according to the surface tension of jeting surface, the surface tension and the ink gun of ink.
Figure 1A, 1B and 2 demonstrate the behavior of the ink on jeting surface when carrying out wiping by a wiping scraper plate in the capillary situation that surface tension at ink is higher than jeting surface.Shown in Figure 1A, be higher than in the capillary situation of jeting surface 11 in the surface tension of ink, ink residue 1104 drops on jeting surface and jeting surface 11 keep relative higher contact angle.Therefore, even when not providing ink gun to use liquid, also can carry out gratifying relatively wiping along moving by wiping scraper plate 9 by the direction shown in the arrow shown in Figure 1B.
But when comprising pigment, high molecular polymer etc. in ink, as shown in Figure 2, the wiping residue 1104 ' of pigment and high molecular polymer can be stayed on the jeting surface 11.Specifically, attached to ink residue 1104 evaporation dryings on the jeting surface 11 time, the wiping residue appears easily.
Therefore, when staying the wiping residue, the pigment and the high molecular polymer that are included in the wiping residue 1104 ' deposit gradually.Then, pigment condenses in the material that is deposited.Therefore, this is accumulated on the jeting surface.By carrying out pigment material (pigment) that wiping will condense in this state once more when peeling off, the pigment material scratch of condensing that jeting surface 11 can have been peeled off with particle diameter of increase.Therefore, the scratch of jeting surface makes the surface property of jeting surface change, thereby causes in some cases jet performance being caused negative effect.
Therefore, use liquid with the ink residue on the dissolving jeting surface, can suppress to occur the shortcoming of ink residue build-up by ink gun is provided.But, as mentioned above, when the macromolecular compound film that is dissolved with liquid by ink gun forms and has the viscosity of increase, be very difficult to carry out wiping by wiping scraper plate 9.And, change the surface property of jeting surface by film, and damaged the jet performance of record head thus.
In order to address these problems, thereby the present invention can remove the ink residue by suitably stipulating jeting surface, ink and ink gun effectively reliably with the relativeness between the surface tension of liquid from jeting surface.Therefore, the inventor finds, change (comprising damage) even when using paint ink, also can remove effectively with the surface property that suppresses jeting surface, can realize sufficient cleaning by satisfying following relation thus attached to the ink residue on the printhead:
F γ s＜I γ s, F γ s＜R γ s (1) simultaneously
Wherein R γ s is the surface tension of ink gun with liquid, and F γ s is the surface tension of jeting surface, and I γ s is the surface tension of ink.
In addition, the inventor finds the more preferably following relation of regulation:
Fγs＜Iγs＜Rγs (2)。
Fig. 3 A and 3B demonstrate regulation jeting surface, ink and ink gun as shown in Equation (1) with the situation of the relativeness between the surface tension of liquid in when carrying out wiping by a wiping scraper plate ink residue on jeting surface and ink gun with the behavior of liquid.When satisfying this regulation, both are present on the jeting surface 11 with relative low wetting state as shown in Figure 3A with liquid 16 for ink residue 1104 and ink gun, and ink gun moves in the pushing that is subjected to wiping scraper plate 9 smoothly with liquid 16.When ink gun contacted ink residues 1104 with liquid 16, the ink residue was dissolved in ink gun with in the liquid.In this respect, because ink and ink gun are higher than the surface tension of jeting surface with the surface tension of liquid, the ink gun that then wherein is dissolved with the ink residue reduces with respect to jeting surface with the wetability of liquid, and ink gun moves in the pushing that is subjected to wiping scraper plate 9 smoothly with liquid shown in Fig. 3 B thus.
Specifically, when carrying out regulation as shown in Equation (2), have ink residue than low surface tension with respect to ink gun with liquid and be dissolved in and have higher capillary ink gun with in the liquid.In other words, the ink residue becomes and has higher capillary material, thereby causes having lower wetability with respect to jeting surface, and when surrounding with liquid by ink gun by 9 pushings of wiping scraper plate with motion smoothly.
On the other hand, when not satisfying concerning shown in the formula (1), for example in the situation of I γ s＜F γ s, the ink residue trends towards becoming wetting with respect to jeting surface, can not carry out the pushing of wiping scraper plate 9 smoothly thus, and occur the wiping residue as shown in Figure 2 easily.In the situation of R γ s＜F γ s, the ink gun that wherein is dissolved with the ink residue with the wiping residue of liquid self since same cause also stay.The shortcoming that is produced when staying these wiping residues as mentioned above.
Satisfy the jeting surface, ink of relation of formula (1) preferred formula (2) and ink gun by suitably regulation as implied above with the relativeness between the surface tension of liquid, can suppress the variation (comprising damage) of the surface property of jeting surface, can realize abundant cleaning.It is to be noted, will describe embodiment more specifically below.

Fig. 9 is a schematic side elevation, demonstrates related to the present invention and from the embodiment of the cleaning device seen by the direction shown in the arrow of Fig. 4.
By elastic component for example the wiping scraper plate 9A and the 9B that make such as rubber be fixed on the wiper support 10.Wiper support 10 can be along the left and right directions shown in the figure (direction vertical with the main scanning direction of record head 1, and inkjet mouth is arranged along this direction) motion. Wiping scraper plate 9A and 9B in height differ from one another.Therefore, when the jeting surface 11 of sliding-contact record head 1, the former bending is relatively large, therefore make its sidepiece contact jeting surface 11, and latter's bending is less relatively, therefore makes head portion contact jeting surface 11.
In clean operation, at first,, the wiping scraper plate transmits ink gun liquid by being contacted with feeding mechanism 12 making record head 1 wait in the state in the position of departing from original position or before record head 1 moves to original position.Then, make the position of wiper support 10 shown in turning back in the figure, and record head is arranged in the original position, and make wiper support 10 afterwards again along moving by the direction shown in the arrow.In this motion process, begin relatively long wiping scraper plate 9A and contacts jeting surface 11 at first slidably, and following than short wiping scraper plate 9B relatively and moving.
Figure 10 is the key diagram of this process.Wiping scraper plate 9A bending is relatively large, and therefore its sidepiece (belly) sliding-contact jeting surface 11 with effectively with ink gun with liquid 16 transmission and be applied on the jeting surface 11.Even exist on the jeting surface 11 under the situation of ink residue 1104, with liquid 16 ink residue 1104 is dissolved by applying ink gun.The amount that is applied is preferably in the scope of wiping operation 0.05 to 0.5mg each time.Then, the head portion of wiping scraper plate 9B (edge) contacts jeting surface 11 so that effectively the dissolved substance of ink residue is wiped off in this state.Therefore, record head is cleaned.At this moment, the surface characteristic of wiping scraper plate 9B is set at the surface tension (its wettability with respect to ink is set at the wettability that is higher than jeting surface) that is higher than jeting surface 11.Thus, the dissolved substance of ink residue trends towards moving to wiping scraper plate 9B from jeting surface 11, thereby enables to get on except that the dissolved substance of ink residue from jeting surface effectively.
It is to be noted that because wiping, the dissolved substance of ink residue is attached on the wiping scraper plate 9B.It under the gravity effect along the wiping scraper plate when dirty, the position that can be provided at the wiper support 10 shown in being lower than receives its member.
But, be preferably in be provided for contacting wiping scraper plate 9A and 9B near the feeding mechanism 12 device (sponge, strigil etc.) to receive dissolved substance on one's own initiative from wiping scraper plate or top process, clean wiping scraper plate thus.If ink gun in that wiping scraper plate 9A and 9B are transmitted after being in the state of cleaning, then can be prepared wiping operation next time with liquid immediately.
Keep ink gun to be used to carry out above-mentioned cleaning equally with the structure optimization of the performance of liquid.This is owing to following reason.The material of wiping scraper plate 9A, shape, size and should be so definite with respect to the position of sliding-contact target, thereby along with obtaining desired conveying capacity with feeding mechanism 12 and jeting surface 11 sliding-contacts.In this respect, conveying capacity is for sending the amount of wiping scraper plate to from feeding mechanism 12 and sending the amount of jeting surface 11 from wiping scraper plate 9A to.On the contrary, when the ink gun that is caused by environmental change changes greatly with liquid weight and physical property, can not obtain desired conveying capacity, may occur clean-up performance thus and reduce.
(relation between regulation of the present invention and wiping scraper plate)
In the present invention, be defined in jeting surface, ink and ink gun and satisfy above-mentioned formula (1), the preferred in addition relation that satisfies top formula (2) with the relativeness between the surface tension of liquid.
This makes ink gun can be applied to reliably on the jeting surface 11 with liquid, and mixes with the ink residue and stir.Therefore, can be easy to remove the ink residue of firm attachment on jeting surface etc.And, after having carried out repeatedly wiping operation, also can keep the initial surface property (for example, hydrophobic performance) of jeting surface even this effect makes, and can keep stable record performance for a long time thus.In addition, because even the ink that comprises high molecular polymer in use is when disperseing pigment as colorant or used when comprising dyestuff as the ink of colorant and also can realize the cleaning of record head under the situation that does not stay the wiping residue, so can realize effect of the present invention.Thus, improved the stability of record performance.
Relation between the structure of regulation of the present invention and employed wiping scraper plate has been described here.
The optimum condition of wiping scraper plate at first has gratifying wettability with respect to ink.Secondly, has preferred to a certain extent wettability with liquid, when as shown in Figure 3A and 3B the quantity of wiping scraper plate being set at one, to remove liquid from jeting surface 11 with respect to ink gun.The 3rd condition is used for such situation, wherein used two wiping scraper plates as shown in figure 10, and the wiping scraper plate 9A of front applies ink gun liquid, and the operation of swiping of wiping scraper plate 9B subsequently.That is to say that this is the situation that function is separated.In this case, wiping scraper plate 9A preferably has lower wettability with respect to ink gun with liquid, thereby a large amount of ink guns are stayed on the jeting surface 11 with liquid, and wiping scraper plate 9B preferably has higher wettability with respect to the ink gun that wherein is dissolved with the ink residue with liquid (ink residue mixed solution).
When having used two wiping scraper plates as shown in figure 10, satisfy the regulation of formula (1), need simultaneously only to select and the material of ink gun with the relevant wiping scraper plate 9A of liquid, and the material of the selection wiping scraper plate 9B relevant with ink residue mixed solution.
Simultaneously, when shown in Fig. 3 A and 3B, the quantity of wiping scraper plate being set at 1, make ink residue mixed solution be higher than the surface tension in the independent situation of ink residue and in addition select the material of the wiping scraper plate 9 relevant just enough with ink residue mixed solution with respect to the surface tension of jeting surface by the regulation that satisfies formula (2).In other words, ink residue mixed solution has higher surface tension with comparing in the independent situation of ink residue, thereby causes and compare in the situation of individual ink residue, has bigger surface tension difference with jeting surface.Specifically, become lower, thereby making that ink residue mixed solution is easier moves on jeting surface with respect to the wetting of jeting surface.Therefore, when 9 motions of wiping scraper plate, can be easy to from jeting surface 11, ink residue mixed solution be removed.
In other words, in the present invention, even used therein in the structure of a wiping scraper plate,, make and compare the ink residue that has than low surface tension with ink gun with liquid and be dissolved in and have higher capillary ink gun with in the liquid by the relation of regulation formula (2).Like this, by obtaining to have higher capillary ink residue mixed solution, reduced wetability with respect to jeting surface.Ink residue mixed solution moves in the pushing that is subjected to wiping scraper plate 9 smoothly.Therefore, even when use comprises the ink of pigment, high molecular polymer etc., also can clean fully to jeting surface.In addition, by making the surface property of wiping scraper plate 9 be higher than the surface tension of jeting surface 11 (the feasible wettability that is higher than jeting surface with respect to the wettability of ink), then the dissolved substance of ink residue trends towards from jeting surface 11 to 9 motions of wiping scraper plate.Thus, can from jeting surface the dissolved substance of ink residue be removed effectively.
To illustrate by way of example that below more specific embodiment and comparing embodiment verify effect of the present invention.
