液体吐出装置１０００は、インク等の液体を後述するタンクと液体吐出ヘッド３との間で循環させる形態の液体吐出装置である。その循環の形態は、液体吐出ヘッド３の下流側で２つの循環ポンプ（高圧用、低圧用）を稼動することで循環させる、比較例としての循環形態と、液体吐出ヘッド３の上流側で２つの循環ポンプ（高圧用、低圧用）を稼動することで循環させる本発明の循環形態（第一循環形態）とがある。以下、それぞれの循環形態について説明する。 The liquid ejection device 1000 is a liquid ejection device in a form in which a liquid such as ink is circulated between a tank described below and the liquid ejection head 3. The circulation form is a circulation form as a comparative example in which two circulation pumps (for high pressure and low pressure) are operated on the downstream side of the liquid discharge head 3 to circulate, and the circulation form is two on the upstream side of the liquid discharge head 3. There is a circulation mode (first circulation mode) of the present invention in which two circulation pumps (for high pressure and low pressure) are operated to circulate. Hereinafter, each circulation form will be described.
第２循環ポンプ１００４としては、液体吐出ヘッド３の駆動時に使用するインク循環流量の範囲において、一定圧以上の揚程圧を有するものであればよく、ターボ型ポンプや容積型ポンプなどを使用できる。具体的には、ダイヤフラムポンプ等が適用可能である。また第２循環ポンプ１００４の代わりに、例えば圧力制御ユニット２３０に対してある一定の水頭差をもって配置された水頭タンクでも適用可能である。図２に示したように圧力制御ユニット２３０は、それぞれが互いに異なる制御圧が設定された２つの圧力調整機構を備えている。２つの圧力調整機構の内、相対的に高圧設定側（図２でＨと記載）、相対的に低圧設定側（図２でＬと記載）は、それぞれ、液体供給ユニット２２０内を経由して、液体吐出ユニット３００内の共通供給流路２１１、共通回収流路２１２に接続されている。液体吐出ユニット３００には、共通供給流路２１１、共通回収流路２１２、各記録素子基板と連通する個別流路２１５（個別供給流路２１３、個別回収流路２１４）が設けられている。共通供給流路２１１には、圧力調整機構Ｈが、共通回収流路２１２には圧力調整機構Ｌが接続されており、２つの共通流路間に差圧が生じている。個別流路２１５は、一対の共通流路のうち一方の共通供給流路２１１と他方の共通回収流路２１２とを接続し、記録素子基板１０の吐出口１３と連通している。かかる構成により、液体の一部が、共通供給流路２１１から記録素子基板１０の内部流路を通過して共通回収流路２１２へと流れる流れ（図２の矢印）が発生する。 As the second circulating pump 1004, a pump having a head pressure equal to or higher than a certain pressure within a range of the ink circulation flow rate used when driving the liquid ejection head 3 may be used, and a turbo pump or a positive displacement pump may be used. Specifically, a diaphragm pump or the like is applicable. Further, instead of the second circulation pump 1004, for example, a head tank arranged with a certain head difference with respect to the pressure control unit 230 can be applied. As shown in FIG. 2, the pressure control unit 230 includes two pressure adjusting mechanisms, each of which has a different control pressure. Of the two pressure adjusting mechanisms, the relatively high pressure setting side (denoted by H in FIG. 2) and the relatively low pressure setting side (denoted by L in FIG. 2) are each passed through the liquid supply unit 220. Are connected to a common supply channel 211 and a common recovery channel 212 in the liquid discharge unit 300. The liquid discharge unit 300 is provided with a common supply channel 211, a common recovery channel 212, and individual channels 215 (individual supply channels 213 and individual recovery channels 214) that communicate with each printing element substrate. A pressure adjusting mechanism H is connected to the common supply channel 211, and a pressure adjusting mechanism L is connected to the common recovery channel 212, and a differential pressure is generated between the two common channels. The individual flow path 215 connects one common supply flow path 211 and the other common recovery flow path 212 of the pair of common flow paths, and communicates with the discharge port 13 of the printing element substrate 10. With such a configuration, a flow (arrow in FIG. 2) occurs in which a part of the liquid flows from the common supply channel 211 to the common recovery channel 212 through the internal channel of the recording element substrate 10.
第１循環形態では、メインタンク１００６内のインクは、補充ポンプ１００５によってバッファタンク１００３に供給される。その後インクは２つの流路に分けられ、液体吐出ヘッド３に設けられた圧力制御ユニット２３０の作用で高圧側と低圧側の２つの流路で循環する。高圧側と低圧側の２つの流路に分けられたインクは、第１循環ポンプ（高圧側）１００１および第１循環ポンプ（低圧側）１００２の作用で液体接続部１１１を介して液体吐出ヘッド３に供給される。その後、第１循環ポンプ（高圧側）１００１および第１循環ポンプ（低圧側）１００２の作用で液体吐出ヘッド内を循環したインクは、圧力制御ユニット２３０を経て、液体接続部１１１を介して液体吐出ヘッド３から排出される。排出されたインクは、第２循環ポンプ１００４によってバッファタンク１００３に戻される。 In the first circulation mode, the ink in the main tank 1006 is supplied to the buffer tank 1003 by the refill pump 1005. Thereafter, the ink is divided into two flow paths, and circulates in two flow paths on the high-pressure side and the low-pressure side by the operation of the pressure control unit 230 provided in the liquid ejection head 3. The ink divided into two flow paths of the high pressure side and the low pressure side is supplied to the liquid ejection head 3 via the liquid connection part 111 by the operation of the first circulation pump (high pressure side) 1001 and the first circulation pump (low pressure side) 1002. Supplied to Thereafter, the ink circulated in the liquid discharge head by the operation of the first circulating pump (high pressure side) 1001 and the first circulating pump (low pressure side) 1002 passes through the pressure control unit 230, and is discharged through the liquid connection unit 111. It is discharged from the head 3. The discharged ink is returned to the buffer tank 1003 by the second circulation pump 1004.
第１循環形態で圧力制御ユニット２３０は、単位面積あたりの吐出量の変化によって生じる流量の変動があっても、圧力制御ユニット２３０の上流側（即ち液体吐出ユニット３００側）の圧力変動を予め設定された圧力を中心として一定範囲内に安定させる。圧力制御ユニット２３０を構成する２つの圧力調整機構としては、圧力制御ユニット２３０よりも上流側の圧力を、所望の制御圧を中心とした一定範囲以下の変動で制御できるものであれば、どのような圧力調整機構を用いてもよい。一例としては所謂「背圧弁・背圧レギュレータ」と呼ばれる背圧型圧力調整弁機構を採用することができる。本実施形態の循環流路では、第２循環ポンプ１００４によって、液体供給ユニット２２０を介して圧力制御ユニット２３０の下流側を加圧している。このようにすると液体吐出ヘッド３に対するバッファタンク１００３の水頭圧の影響を抑制できるので、液体吐出装置１０００におけるバッファタンク１００３のレイアウトの選択幅を広げることができる。第２循環ポンプ１００４の代わりに、例えば圧力制御ユニット２３０に対して所定の水頭差をもって配置された水頭タンクであっても適用可能である。第１循環形態は図２の循環形態と同様に、圧力制御ユニット２３０は、それぞれが互いに異なる制御圧が設定された２つの圧力調整機構を備えている。２つの圧力調整機構の内、高圧設定側（図３で２３０Ｈと記載）、低圧設定側（図３で２３０Ｌと記載）はそれぞれ、液体供給ユニット２２０内を経由して、液体吐出ユニット３００内の共通供給流路２１１および共通回収流路２１２に接続されている。２つの圧力調整機構により、共通供給流路２１１の圧力を共通回収流路２１２の圧力より相対的に高くすることで、共通供給流路２１１から個別流路２１５および各記録素子基板１０の内部流路を介して共通回収流路２１２へと流れるインク流れが発生する。 In the first circulation mode, the pressure control unit 230 presets the pressure fluctuation upstream of the pressure control unit 230 (that is, the liquid discharge unit 300 side) even if there is a flow rate fluctuation caused by a change in the discharge amount per unit area. The pressure is stabilized within a certain range around the applied pressure. As the two pressure adjusting mechanisms constituting the pressure control unit 230, any pressure adjusting mechanism that can control the pressure on the upstream side of the pressure control unit 230 with a fluctuation within a certain range around a desired control pressure can be used. A simple pressure adjusting mechanism may be used. As an example, a so-called "back-pressure valve / back-pressure regulator" can be employed. In the circulation flow channel of the present embodiment, the second circulation pump 1004 pressurizes the downstream side of the pressure control unit 230 via the liquid supply unit 220. In this way, the influence of the head pressure of the buffer tank 1003 on the liquid ejection head 3 can be suppressed, so that the selection range of the layout of the buffer tank 1003 in the liquid ejection device 1000 can be expanded. Instead of the second circulation pump 1004, for example, a water head tank arranged with a predetermined head difference with respect to the pressure control unit 230 can be applied. In the first circulation mode, similarly to the circulation mode of FIG. 2, the pressure control unit 230 includes two pressure adjusting mechanisms, each of which has a different control pressure. Of the two pressure adjustment mechanisms, the high pressure setting side (denoted as 230H in FIG. 3) and the low pressure setting side (denoted as 230L in FIG. 3) each pass through the inside of the liquid supply unit 220 and the inside of the liquid ejection unit 300. The common supply channel 211 and the common recovery channel 212 are connected. By making the pressure of the common supply flow path 211 relatively higher than the pressure of the common recovery flow path 212 by the two pressure adjusting mechanisms, the flow from the common supply flow path 211 to the individual flow paths 215 and the internal flow An ink flow that flows to the common recovery channel 212 via the path is generated.
