In addition, this failure detector 100 also comprises in addition: presser unit 77, and the compression chamber 3 (first compression chamber) that is used for to liquid container 1 carries forced air; Operating portion 79 is used for input fault detection order; And display part 81, show the fault detect result.
Here, to describing as the liquid container 1 of checking object.
As shown in Figure 2, liquid container 1 comprises: container body 5, divide the compression chamber 3 of the presser unit pressurization that is formed with pressurized unit 77 or inkjet recording device; Ink bag (liquid containing chamber) 7, storage ink also is accommodated in the compression chamber 3, and discharges stored ink by the pressurization of compression chamber 3 from outlet (liquid outlet) 7a; Ink supply port (supply opening) 9 is used for to the printhead supply ink as the inkjet recording device of outside liquid consumer; Ink detection portion 11 between ink bag 7 and ink supply port 9, is used to detect the ink surplus; And switch valve mechanism 12, be configured between ink bag 7 and the ink detection portion 11, and ink capable of blocking is from the inflow of ink bag 7 to ink detection portion 11.
Container body 5 comprises: the compression chamber 3 that is in air-tight state; As the pressurization mouth 13 of gas-pressurized injection portion, as shown by arrow A, this pressurization mouth 3 is used for not shown presser unit and carries forced airs to this compression chamber 3; And the space 44 (second compression chamber) that is in the atmosphere opening state.
This compression chamber 3 is applied in the pressure of gas-pressurized of the presser unit supply of the presser unit 77 of failure detector 100 or inkjet recording device.Thereby the two works comparably to being contained in ink bag 7 in the compression chamber 3 and ink detection portion 11 by presser unit institute applied pressure.
Ink bag 7 is that the outlet 7b with tubular is attached to the distolateral and form of flexible bag 7a, wherein, described flexible bag 7a is by will covering aluminium plural layers edge part each other bonding formation mutually what have that stacked aluminium lamination forms on the flexible resin thin film layer, and described tubular outlet 7b is connected with ink inflow entrance (liquid inflow entrance) 11a of ink detection portion 11.This ink bag 7 covers the aluminium plural layers by use guarantees high gas barrier property.
Ink bag 7 and ink detection portion 11 are by forming interconnective state with chimeric being connected of ink inflow entrance 11a on the outlet 7b.That is, by removing the chimeric of outlet 7b and ink inflow entrance 11a, can be separated from one another.
In addition, be equipped with the encapsulation that is used between ink inflow entrance 11a, carrying out the air-tightness connection on the outlet 7b.Before connecting ink detection portion 11, in ink bag 7, be pre-charged with the ink that is adjusted to high degassing degree state.
Ink detection portion 11 comprises: test section housing 19 has the concave shaped space 19a that ink inflow entrance 11a that is connected with the outlet 7b of ink bag 7 and ink flow export (liquid flowing outlet) 11a that is connected with ink supply port 9 are communicated with; Fexible film 23, the opening of sealing concave shaped space 19a forms transducer room (liquid sensing chamber) 21 thereby divide; Pressure detecting portion 25 is installed on the bottom 19b of concave shaped space 19a; Compression plate (moving-member) 27 relatively is fixed on the fexible film 23 with described pressure detecting portion 25; And compression helical spring (pushing unit) 29, be fitted between described compression plate 27 and the bottom 19b, and compression plate 27 and fexible film 23 are pushed to the direction elasticity of the volume expansion of transducer room 21.
Transducer room 21 preferably constitutes by the opening by fexible film 23 sealing concave shaped space 19a, and wherein said concave shaped space 19a is arranged on the parts that form described transducer room 21, is on the test section housing 19.Fexible film 23 plays the effect that under the pressure of the ink in being fed to transducer room 21 compression plate 27 is applied the barrier film of displacement.In order to improve accuracy of detection, enable to detect the small pressure of ink and change, fexible film 23 preferably has enough flexibilities.By said structure, can form transducer room 21 by the so simple manufacturing process of opening, thereby can easily make the transducer room 21 of high seal with fexible film 23 hot welds sealing concave shaped space 19a.
In test section housing 19, be integrally formed therewith ink discharge outlet 11c at an end of the perisporium that divide to form concave shaped space 19a, and on the perisporium relative, run through and formed the ink flow export 11b that is communicated with ink supply port 9 with this ink discharge outlet 11c.Though do not illustrate among the figure, in ink supply port 9, valve system is installed, when on the box installation portion that print cartridge is installed to inkjet recording device, this valve system is opened stream by the insertion that is installed in the ink supply pin on the box installation portion.
Pressure detecting portion 25 in the ink detection portion 11 comprises: base plate 31, and in the time can supplying ink in transducer room 21 from ink bag 7, compression plate 27 leaves this base plate 31 under the effect of the pushing force of compression helical spring 29; Ink path of navigation 33, it is formed in the recess on the base plate 31; And piezo-type sensor (piezo-electric type detecting unit) 35, when applying vibration for ink path of navigation 33, detect the state of the free vibration that produces along with described vibration.
Whether this piezo-type sensor 35 can be covered the state (amplitude of residual vibration or the variation of frequency) that detects different free vibration by compression plate 27 by ink path of navigation 33.
Therefore, the state that for example is arranged on the free vibration that the control part in the inkjet recording device detected according to piezo-type sensor 35 detects the distortion of the fexible film 23 of supporting compression plate 27, the volume-variation in thus can detecting sensor chamber 21.That is, as the ink detection portion 11 of detecting unit by be arranged on inkjet recording device on checkout gear be connected and bring into play function as the part of checkout gear.
The press direction of compression helical spring 29 of pushing compression plate 27 be the direction that enlarges of the volume of transducer room 21 as described above (with the side of configuration piezo-type sensor 35 in the opposite direction).(when the ink of ink bag 7 does not also exhaust) thereby under normal conditions, compression plate 27 and base plate 31 are kept the state of leaving as shown in Figure 2.
And,,, also keep the described state that leaves even the pressure of presser unit is applied in the compression chamber 3 when surplus when enough ink surpluses are arranged in ink bag 7.That is, compression helical spring 29 has a pushing force, and the ink feed pressure from ink bag flow sensor chambers 21 7 matches this pushing force with depressing in adding of presser unit, the opposing presser unit pressure and make compression plate 27 leave the bottom 19b.
On the other hand, as shown in Figure 3, when the ink of ink bag 7 is in spent condition and stops to flow into inks from ink bag 7, perhaps when the time from ink supply port 9 attraction inks, under the effect of the negative pressure in transducer room 21, compression plate 27 is resisted the pushing force of compression helical springs 29 and is moved, and closely contacts with base plate 31.
As shown in Figure 3, under compression plate 27 and base plate 31 tight state of contact, be formed on recess on the base plate 31, be that ink path of navigation 33 matches with compression plate 27 and divides to form and detect the space, when compression plate 27 was in the state that leaves base plate 31 as shown in Figure 2, this ink path of navigation 33 was opened to transducer room 21.Compression plate 27 has in the zone relative with the vibration plane of piezo-type sensor 35 and the substantially parallel face of described vibration plane.
In ink detection portion 11, when the forced air of supplied with pressurized chamber 3 to the effect of the pressurization of ink bag 7 under and from ink bag 7 during to transducer room 21 supply inks, the ink feed pressure matches with the pushing force of compression helical spring 29 and makes fexible film 23 dilatancy upward.Because compression plate 27 leaves base plate 31, ink path of navigation 33 is in to transducer room 21 opened state, and supplies ink from ink supply port 9 to the first side of record by transducer room 21 simultaneously.
Even compression chamber 3 is in the pressurized state of regulation,, then be supplied to the quantity of ink of transducer room 21 also can reduce from ink bag 7 if the ink that is contained in the ink bag 7 reduces.Thus, because the pressure in the transducer room 21 reduces, therefore, compression plate 27 moves closer to the base plate 31 with ink path of navigation 33.
Promptly, when the liquid capacity in the transducer room 21 when ormal weight is following, compression plate 27 matches with ink path of navigation 33 as the vibration zone of action and divides and form to detect the space, therefore, the variation of the free vibration state that piezo-type sensor 35 is detected becomes significantly, thereby can be correctly and detect the moment or the state that liquid capacity in the transducer room 21 arrives prescribed level reliably.In the present embodiment, compression plate 27 closely contact with base plate 31 because of the pressure in the transducer room 21 reduce, and match with ink path of navigation 33 and divide the depleted state of ink that the moment that forms the detection space is set at ink bag 7.
Switch valve mechanism 12 is configured between ink bag 7 and the ink detection portion 11, can block ink from the inflow of ink bag 7 to ink detection portion 11.Inflow entrance 37 is communicated with ink bag 7 via ink inflow entrance 11a.Switch valve mechanism 12 has the valve chamber 41 that inflow entrance 37 and flow export 39 are communicated with, and wherein said inflow entrance 37 is connected with ink bag 7, and described flow export 39 is connected with transducer room 21.Inflow entrance 37 is communicated with ink bag 7 via ink inflow entrance 11a.Flow export 39 is communicated with transducer room 21 via ink drain passageway 11c.
Valve chamber 41 is to constitute by the opening that seals recess 43 with barrier film 45, and wherein said recess 43 is arranged on the parts that form valve chamber 41, is on the test section housing 19.By said structure, can be by forming valve chamber 41 with barrier film 45 hot welds and this simple manufacturing process of opening that seals recess 43, thus can easily make the valve chamber 41 of high seal.
Barrier film 45 is formed by deformable film (compliant member).Can come inaccessible flow export 39 by the distortion (closely contact) of barrier film 45 to valve chamber 41 openings.The configuration space pressurized chambers 3 44 and the next door 46 of barrier film 45 separate.This space 44 is communicated with atmosphere via peristome 48.
In the present embodiment, the negative pressure of the valve chamber 41 that produces from ink supply port 9 attraction inks makes barrier film 45 produce distortion, comes the flow export 39 of obturation to valve chamber 41 openings by this distortion.That is, the ink of the transducer room 21 that attracts from ink supply port 9 makes the valve chamber 41 that is communicated with transducer room 21 via flow export 39 become negative pressure, makes barrier film 45 distortion under the effect of this negative pressure, thereby can export 39 by choking flow.
That is, can under the situation that the mechanism that applies external force is set on the barrier film 45, not constitute switch valve mechanism 12 simply in addition.
Thereby as shown in Figure 4,, make valve chamber 41 become negative pressure and come choking flow outlet 39, just the ink of having blocked from ink bag 7 flows into if by attracting ink from ink supply port 9.If under this state, further attract ink, then compression plate 27 is moved by the mode near base plate 31, and final closely contact is on base plate 31 owing to the pressure in the transducer room 21 reduces from ink supply port 9.
That is,, can make ink bag 7 be in virtual ink spent condition by being communicated with between switch valve mechanism 12 blocking-up and the ink bag 7.Afterwards, when pressurizeed in compression chamber 3, switch valve mechanism 12 opens under the effect from the pressure of ink bag 7, and transducer room 21 turns back to the state of ink.
In this liquid container 1, when the ink capacity in the transducer room 21 (liquid capacity) reaches ormal weight when following, compression plate 27 and ink path of navigation 33 match incompatible division formation as the detection space that vibrates the zone of action, thereby the frequency corresponding to the acoustic resistance of ink path of navigation 33 occurs.The frequency of the acoustic resistance when this frequency ratio compression plate 27 leaves base plate 31 is low, its significant difference.Therefore, the variation of the free vibration state that piezo-type sensor 35 detects also becomes significantly, thereby can be correctly and detect the moment or the state that ink capacity in the transducer room 21 reaches prescribed level reliably.
Promptly, liquid residue detection method according to present embodiment, ink detection portion 11 can attract the ink of transducer rooms 21 under by the state of closing switch valve mechanism 12, promptly carry out under the state that vacuum attraction shrinks at the volume of transducer room 21 from ink supply port 9, and under the state opened of switch valve mechanism 12, above-mentioned liquid container 1 is carried out detecting operation.
By closing switch valve mechanism 12, the blocking-up ink carries out vacuum attraction under the state of ink bag 7 inflows, and transducer room 21 is in virtual ink spent condition.
Therefore, even its type for the liquid container 1 that simultaneously ink bag 7 and transducer room 21 is pressurizeed in, also can be by in the use of inkjet recording device, on one side making liquid container 1 be in virtual ink spent condition, by the volume-variation of ink detection portion 11 detecting sensor chambers 21 confirm the malfunction of this ink detection portion 11 on one side.
Promptly, by close switch valve mechanism 12 and carry out attracting from supply opening transducer room 21 ink vacuum attraction state and open the volume of detecting sensor chamber 21 under the state of switch valve mechanism 12, the having or not and the malfunction of ink detection portion 11 of ink that can detecting sensor chamber 21.
For example, under the state of opening switch valve mechanism 12, detect the signal of ink, and when under the state of closing switch valve mechanism 12, detecting the signal of no ink, in ink bag 7, ink is arranged.
Under the state of opening switch valve mechanism 12, detect the signal of no ink, and when under the state of closing switch valve mechanism 12, also detecting the signal of no ink, in ink bag 7, do not have ink.
Under the state of opening switch valve mechanism 12, detect no ink signal or ink signal is arranged, and when under the state of closing switch valve mechanism 12, having detected ink signal, piezo-type sensor 35 malfunctions.
When liquid container 1 was installed on the failure detector 100, as shown in Figure 1, space 44 was communicated with locking unit 71 via peristome 48.
For example can with the actuator of carrying forced air as the blocking mechanism of closing switch valve mechanism 12, be locking unit 71.Thereby when by locking unit 71 during to space 44 pressurised air, barrier film 45 to be being subjected to displacement with modes that recess 43 closely contact, and can block liquid from ink bag flow sensor chambers 21 7 by sealing flow export 39.
The structure of blocking mechanism of closing switch valve mechanism 12 is as follows: attract mechanism 73 to attract inks and the negative pressure of the valve chamber 41 that produces makes barrier film 45 distortion from ink supply port 9, and thus can inaccessible flow export 39 to valve chamber 41 openings.At this moment, can omit the locking unit 71 of failure detector 100.
Control part 75 can use the computer of for example being furnished with CPU.Control part 75 is except the action of control locking unit 71, attraction mechanism 73, can also will make comparisons, thereby the quality of carrying out ink detection portion 11 is judged at detection signal and the setting of controlling locking unit 71, return from the piezo-type sensor 35 of ink detection portion 11 when attracting mechanism 73.
Promptly, in the fault detect that failure detector 100 is carried out, close switch valve mechanism 12 by locking unit 71, and under the state of blocking-up, carry out vacuum attraction, make transducer room 21 be in virtual ink spent condition thus by attraction mechanism 73 from the ink inflow of ink bag 7.Therefore, even its type for the liquid container 1 that simultaneously ink bag 7 and transducer room 21 is pressurizeed in, shrink by the volume that under virtual ink spent condition, makes transducer room 21, and judge from the detected value of ink detection portion 11 75 pairs of this moments by control part, also can detect ink detection portion 11 feeds back to liquid when liquid is depleted maloperation.
Specify the order of the fault detection method of 100 pairs of ink detection portions 11 of failure detector below.
Fig. 5 is the sequential flowchart that the fault detection method of failure detector shown in Figure 1 100 is shown.
When the fault of the ink detection portion 11 in the tracer liquid container 1, at first come latch switch valve system 12 (S1) by locking unit 71.
Then by attracting mechanism 73 to carry out vacuum attraction (S2) from supply opening 9.
When further carrying out vacuum attraction, the pushing force of opposing compression helical spring 29 under the effect of the negative pressure of compression plate 27 in transducer room 21 and moving and closely contacts with base plate 31.Thus, as shown in Figure 4, the volume of transducer room 21 shrinks (S3).
At this moment, control part 75 detects the detection signal (S4) that returns from the piezo-type sensor 35 of ink detection portion 11.
Test section 75 is judged according to this detected value and is had or not ink (S5), at this moment, if return the detection signal that does not have ink from ink detection portion 11, judges that then ink detection portion 11 is good (S6).
On the other hand, if the detection signal that returns ink from ink detection portion 11 is then judged ink detection portion 11 bad (S7).
That is, when carrying out vacuum attraction, transducer room 21 is in virtual ink spent condition, returns the detection signal of ink from ink detection portion 11 if ignore above-mentioned situation, judges that then ink detection portion 11 is for bad.
Control part 75 is presented at (S8) on the display part 81 according to described judged result with the fault detect result.
