Ink cartridge 3 stores the ink 20 being supplied to ink gun 2.The ink 20 that ink blowoff 1 uses is such as pigment system ink, comprises metallic (electrode material, i.e. Au, Ag, Cu, Pd, Ni) or the ink of electroconductive particle, and in liquid, be dispersed with particle components (pigment, metallic etc.).In addition, ink 20, except metallic etc., can also comprise pottery, resin etc.Further, the viscosity of preferred ink 20 is the low viscosity of below 40mPas, is more preferably the viscosity of 10mPas ~ 25mPas.The capacity of ink cartridge 3 is such as 50mL.
Fig. 2 is the schematic diagram of the structure example of the ink cartridge 3 represented involved by embodiments of the present invention.As shown in Figure 2, ink cartridge 3 comprises: cylindrical shell 5, pipeline 4 and tubing pump (circulation portions) 6.In addition, in the bottom of cylindrical shell 5, the supply port 7 of the entrance as stream ink 20 being supplied to ink gun 2 is provided with.Cylindrical shell 5 is formed as circular, and from leading to the part that the direction of flowing along the ink 20 shown in arrow near the stream leading to open and close valve 33,34 near the stream of ink gun 2 cuts off about 1/4.The inner pipeline 4 by ink 20 as cylindrical shell 5 a part and be connected with the part cut off.Using the connecting portion towards the cylindrical shell 5 near the stream of ink gun 2 and pipeline 4 as an end 42, cylindrical shell 5 near the stream leading to open and close valve 33,34 is positioned at than the position of another end 41 closer to below as end 42,41, one, another end with the connecting portion of pipeline 4.In this case, the length of the circulating path of ink 20 and the annulus length of ink cartridge 3 roughly equal.In addition, when circulating path is circular, the delay of the particle components of ink 20 can also be suppressed.
Cylindrical shell 5 is formed by polypropylene, SUS, glass etc.In addition, pipeline 4 is pipelines of silicon class, as long as and the pipeline of the material of being out of shape according to the pressing force from outside, be not particularly limited.In the present embodiment, the internal diameter of pipeline 4 is set to such as 3mm.
In the centre of pipeline 4, possess the circulation portions of tubing pump 6 as the ink 20 sent in pipeline 4.The action of tubing pump 6 is controlled by control device 37.Fig. 3 is the schematic diagram of the structure example of the tubing pump 6 of the ink cartridge 3 represented involved by embodiments of the present invention.
In tubing pump 6, be that the inner circumferential of the framework 63 of circular is configured with and has flexible pipeline 4 along inner circumferential, and utilize a pair roller bearing 62 on the position respect to one another being arranged on the rotor 61 rotated along the direction identical with the flow direction of ink 20 to press pipeline 4.By the rotation of rotor 61, a pair roller bearing 62 is moved along pipeline 4 in the mode contacted with pipeline 4, sent the ink 20 in pipeline 4 by pressing pipeline 4.In the example of fig. 3, because rotor 61 is rotated in a clockwise direction, therefore ink 20 aspirates from an end 42 of pipeline 4 and sends to another end 41.
After a pair roller bearing 62 passes through, the part that pipeline 4 is pressed and is out of shape reverts to original state because of restoring force, and volume restores to the original state.Because the volume of pipeline 4 restores to the original state, therefore ink 20 can be aspirated from an end 42 continuously.
Because tubing pump 6 does not use valve, be therefore suitable for transporting the such sticking liquid of tool of ink 20, as long as and replace unique running stores and pipeline 4, thus there is higher maintenance.Certainly, be not limited to the tubing pump 6 of structure shown in Fig. 3, as long as can press pipeline 4 from the outside of deformable pipeline 4 thus make the actuator that ink 20 circulates be used as circulation portions.
As in the embodiment described in, utilize cylindrical shell 5 and pipeline 4 that the circulating path of ink 20 is formed as closed loop shape, and press pipeline 4 from the outside of deformable pipeline 4 thus ink 20 is circulated, if this structure, the possibility producing pollutant in ink 20 is also less.
Be back to Fig. 1, be connected with the air on the top for aspirating cylindrical shell 5 on the top of the cylindrical shell 5 of ink cartridge 3 and make the inside of ink cartridge 3 produce the free-air path 31 of negative pressure state (1 ~ 3kPa) and the gas supplying path 32 for supplying compressed air (Compressed Gas).All the time do not drip from nozzle 21 for making ink 20, possess the pump orifice 30 of the air on the top of the cylindrical shell 5 of suction ink cartridge 3 on the top of the cylindrical shell 5 of airtight ink cartridge 3, make the top of cylindrical shell 5 be in negative pressure state by the air on the top of aspirating cylindrical shell 5 from pump orifice 30.Thus, by stopping supplying ink 20 to ink gun 2 in negative pressure state, and ink 20 continuous circulation in ink cartridge 3 can be made until eliminate the sedimentation etc. of the particle components of the ink 20 in ink cartridge 3 bottom.
On the other hand, when delivery ratio prints from nozzle 21 spray amount more ink 20 (during removing), by closing the negative pressure open and close valve 33 be arranged on free-air path 31, and open the compressed air open and close valve 34 be arranged on gas supplying path 32, compressed air is supplied in ink cartridge 3.By being supplied to by compressed air in ink cartridge 3, the ink 20 in ink cartridge 3 can be extruded from the opening portion 22 of nozzle 21, and can delivery ratio printing time the ink 20 (removing action) of amount more that sprays from nozzle 21.In addition, negative pressure open and close valve 33 is connected to vavuum pump 35 via pressure-regulating valve.In addition, compressed air open and close valve 34 is connected to compressed air supply source 36 via pressure-regulating valve.Further, the opening and closing of negative pressure open and close valve 33 and compressed air open and close valve 34 is controlled by control device 37.
