Definitions
- the present invention relates to a droplet discharge device that performs printing by discharging a discharge liquid (ink).
- a print head and an ink tank are usually connected by a dedicated flow path, and ink stored in the ink tank via this flow path is connected to the print head. Supplied.
- the supplied ink is pushed out as an ink droplet from the nozzle hole by a pressure wave generated by a pressure generating device installed in the print head (for example, an actuator such as a heater or a piezoelectric element in an on-demand type ink jet head).
- a pressure generating device installed in the print head (for example, an actuator such as a heater or a piezoelectric element in an on-demand type ink jet head).
- the ink meniscus (ink surface state) of the nozzle holes when the print head is not operating needs to be held stably.
- the ink In order to maintain the meniscus, the ink must be given a force that opposes the force when the ink drop naturally falls by gravity.
- the above-described on-demand print head has a mechanism for ejecting droplets, it has no mechanism for preventing ink from leaking through the print head when the print head is not operating. Not. Therefore, a method of applying a pressure (back pressure) so that ink does not leak is used.
- the minimum control range of the back pressure required in the ink jet discharge apparatus is about 10 mmH 2 O or less, and the difference from the pressure of the external atmosphere is extremely small. For this reason, it is difficult to accurately adjust this pressure region in a system using a conventional vacuum pump or the like.
- Patent Document 5 As another method for providing back pressure, there is an example in which the porous body as described above is not used (see Patent Document 5 below).
- a movable lid that can be raised and lowered is provided at a gas-liquid interface portion of the stored ink, and a negative pressure is generated at the lid portion to directly hold the ink.
- this method requires a separate spring mechanism that pushes up the movable lid to maintain the negative pressure, and there is a concern that it may be a restriction on the apparatus configuration.
- the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a technique capable of accurately controlling the back pressure in the ink tank.
- the present invention has a discharge head, an ink tank, and a valve device.
- the valve device When the valve device is opened, the discharge head is connected to the ink tank and the valve device is closed.
- the discharge head is cut off from the ink tank, and a suction member having a porous body is disposed in the ink tank, and in the liquid storage state where ink is stored in the ink tank.
- the at least part of the suction member is in contact with the inner wall surface of the ink tank, fixed to the ink tank by a static frictional force, and configured to rise by the capillary force to the middle of the porous body. It is a discharge device.
- the present invention is an ejection device, wherein the ejection head is provided with an ejection port at a position below the ink tank, and when the valve device is opened, the ink in the ink tank passes through the valve device.
- the height at which the ink in the porous body moves to the ejection head and rises is smaller than when the valve device is closed, and a suction force that pulls the ink upward is generated.
- the ejection device is configured to prevent the ink from leaking. When the amount of the ink in the ink tank is constant, the suction member is stopped by the static friction force, and the amount of the ink in the ink tank is reduced by a certain amount or more.
- the suction force is larger than the static friction force, and the suction member moves downward.
- the present invention is a discharge device, wherein the ink tank is provided with an external connection port that connects an internal space of the ink tank to an external atmosphere where the discharge port is exposed.
- the back pressure in the ink tank can be controlled with a minimum control pressure range of 1 mmH 2 O. Since the back pressure is accurately controlled, ink leakage from the ejection port is prevented, and the meniscus is stabilized. Since the meniscus is stabilized, the droplet discharge state such as the droplet discharge amount from the discharge port and the landing position accuracy is also stabilized. Since the amount of ink in contact with the porous body is small, the ink component is not easily altered.

Abstract
Description
本発明は吐出装置であって、前記吐出ヘッドには前記インクタンクよりも下方位置に吐出口が設けられ、前記弁装置を開けた時には、前記インクタンク内の前記インクが前記弁装置を通って前記吐出ヘッドへ移動し、前記多孔質体内の前記インクが上昇した高さは、前記弁装置を閉じた状態よりも小さくなって前記インクを上方に引き上げる吸引力が発生し、前記吐出口から、前記インクが漏れないようにされた吐出装置である。
本発明は吐出装置であって、前記インクタンク内の前記インクの量が一定の時には、前記吸引部材は前記静止摩擦力により静止し、前記インクタンク内の前記インクの量が一定量以上減少すると、前記吸引力が前記静止摩擦力よりも大きくなり、前記吸引部材が下方に移動する吐出装置である。
本発明は吐出装置であって、前記インクタンクには、前記インクタンクの内部空間を、前記吐出口が露出する外部雰囲気に接続する外部接続口が設けられた吐出装置である。
台7の側方にはレール37が延設されており、可動腕8は不図示の移動手段によってレール37の延設方向に沿って往復移動する。図1(a)では、レール37と、可動腕8と、可動腕8がレール37上に乗るための装置は省略してある。
インクタンク11の天井には外部接続口47が設けられ、底面には導入口45と導出口46がそれぞれ設けられている。外部接続口47と、導入口45と、導出口46には、それぞれ配管等の流路9、12、13の一端が接続されている。
導入口45に接続された流路9の他端はメインタンク4に接続され、導出口46に接続された流路12の他端は吐出ヘッド3に接続されており、これらの流路9、12の途中にはコック(弁装置)17、18が設けられている。
また、吸引部材15の側面(ここではシール部材16)とインクタンク11内壁面も、インク21に対する濡れ性が高くされ、吸引部材15の側面とインクタンク11内壁面との間の隙間19は毛細管力によりインク21が上昇する程狭くされている。従って、インクタンク11に蓄液されたインク21は多孔質体10の内部と、吸引部材15とインクタンク11内壁面との間の隙間19に、毛細管力で吸い上げることができる。
上記理論式(1)中、hは水頭差(m)、Tはインクの表面張力(N/m)、θはインクの多孔質体10に対する接触角、ρはインク密度(kg/m3)、gは重力加速度(m/s2)、rは毛細管の半径(m)である。
吸引部材15の側面の一部はインクタンク11の内壁面に接触し、多孔質体10は静止摩擦力でインクタンク11に固定されている。吸引部材15の長さ(多孔質体10両底面間の距離)は、インクタンク11の底面から天井までの高さよりも短くされている。水頭差h1、h2が上記理論式(1)で求められる理論値に達した後もインク21の供給を続け、インク21の圧力が静止摩擦力と吸引部材15の重量の合計を超えると、吸引部材15が押し上げられる。
このとき、メインタンク4からインクタンク11にインクは補充されないから、蓄液空間41のインク21の液面Hが下降し、毛細管力で多孔質体10に吸引されたインク21には、一緒に下降しようとする力が働く。
