Description
- The present invention relates to an inkjet printing device.
- Hitherto, an inkjet printing device for performing printing by ejecting ink onto a print object, such as fabric, has been proposed. In this inkjet printing device, ink is ejected from the nozzles of the print head. When ink remains in the nozzles and dries, the viscosity of the ink remaining in the nozzles increases, possibly causing clogging in the nozzles. In order to remove ink having an increased viscosity from the nozzles of the print head, a so-called blank ejection operation, in which the ink in the nozzles is forcibly removed with a suction pump or the like, is regularly performed (e.g., Patent Document 1).
-
- Patent Document 1:
JP7-246710A - The ink ejected by means of the above-mentioned blank ejection operation, etc., is discarded without being used; such unused ink is needlessly wasted. In view of this problem, an object of the present invention is to provide an inkjet printing device capable of effectively using unused ink ejected by means of a blank ejection operation, etc.
- The inkjet printing device according to the present invention performs printing by ejecting ink onto a print object. The printing device according to the present invention includes a first ink tank for storing ink, a second ink tank for storing the ink supplied from the first ink tank, a print head provided with nozzles for ejecting the ink supplied from the second ink tank onto a print object, a deaerating means for removing air bubbles from the ink, the deaerating means being disposed between the second ink tank and the print head, and a recycle flow path for returning unused ink ejected from the nozzles of the print head back to the second ink tank.
- The above-described inkjet printing device is provided with a recycle flow path for returning, back to the second ink tank, unused ink ejected by means of a blank ejection operation or the like from the nozzles of the print head. The blank ejection operation is performed for preventing the nozzles from clogging. The unused ink ejected by means of the blank ejection operation or the like can thereby be effectively used. The ink recycled in the above manner sometimes includes air bubbles, etc.; however, because a deaerating means is disposed between the second ink tank and the print head of the present invention, ink with no air bubbles can be supplied to the print head. Further, because a deaerating means is disposed between the second ink tank and the print head, the second ink tank may be an open tank such that the ink is in contact with the air.
- The above-described inkjet printing device can have a variety of configurations. For example, the pressure loss of ink in the deaerating means is preferably 0.1 kPa or less. The resistance from the second ink tank to the print head is thereby reduced, achieving smooth ink supply by means of the hydraulic head system. For the same reason as above, the deaerating means is preferably an external perfusion type.
- The first ink tank, the second ink tank, and the deaerating means may be connected in line in this order. Due to this configuration, the first ink tank may also be an open tank.
- It is preferable that an ink booster pump be further provided for supplying pressurized ink to the nozzles of the print head. This ink booster pump forcibly discharges ink from the nozzles of the print head, reliably preventing the nozzles from clogging.
- It is also preferable to provide a suction pump for suctioning the ink from the nozzles of the print head, in order to forcibly discharge the ink from the nozzles of the print head.
- The inkjet printing device according to the present invention can effectively use unused ink ejected by means of blank ejection operation or the like.

Figure 1 schematically illustrates one embodiment of the inkjet printing device of the present invention. -
Figure 2 is a partial sectional view of one embodiment of the deaerating module of the present invention. - Embodiments of the inkjet printing device of the present invention are described below with reference to the drawings.
- As illustrated in
Fig. 1 , in aninkjet printing device 1, ink stored in afirst ink tank 2 is supplied to asecond ink tank 3 to be temporarily stored in thesecond ink tank 3. After the ink in thesecond ink tank 3 is deaerated with adeaerating module 4, the ink is supplied to aprint head 5. Theprint head 5 then ejects the ink onto a print object to perform printing. Theinkjet printing device 1 further includes asuction pad 6, a suction pump P1, and an ink booster pump P2, which serve as clogging prevention means for preventing the nozzles of theprint head 5 from clogging. Afilter unit 7 is also provided for removing dust, etc., from unused ink ejected by means of a blank ejection operation from theprint head 5 by using the clogging prevention means. - The
first ink tank 2 is an open tank for storing ink to be supplied to thesecond ink tank 3. When the ink in thefirst ink tank 2 is consumed, thetank 2 is replaced with a newfirst ink tank 2. Alternatively, it is also possible to refill thefirst ink tank 2 with ink. Although thefirst ink tank 2 is an open tank, it may be a closed tank, which does not allow the ink to be in contact with the air. The capacity of thefirst ink tank 2 is not limited, and is generally about 5 to 10 L. - The
second ink tank 3 is connected to thefirst ink tank 2 via an ink feed pump P3 and a three-way valve V1. Thesecond ink tank 3 is an open ink tank for temporarily storing ink supplied from thefirst ink tank 2 and ink ejected by means of a blank ejection operation. Thesecond ink tank 3 supplies the ink to theprint head 5 by means of the hydraulic head system. Thesecond ink tank 3 is provided with a liquidsurface detection sensor 31 for detecting the liquid surface of the ink to control the hydraulic head. When the liquidsurface detection sensor 31 detects that the liquid surface of the ink stored in thesecond ink tank 3 is lowered to below the set value while printing is performed, the ink feed pump P3 is operated to supply ink from thefirst ink tank 2 to thesecond ink tank 3. Although thesecond ink tank 3 is an open tank, it may also be a closed tank. The capacity of thesecond ink tank 3 is smaller than that of thefirst ink tank 2, and is generally about 70 to 100 mL. - The
deaerating module 4 is located between thesecond ink tank 3 and theprint head 5. The deaeratingmodule 4 is a unit for removing air bubbles from the ink fed from thesecond ink tank 3 to theprint head 5. More specifically, as shown inFig. 2 , the deaeratingmodule 4 is an external perfusion type, and a plurality ofhollow strings 42 are housed in a hollow tube-like body 41. To reduce the pressure inside eachhollow string 42, at least one of the upper or lower end of eachhollow string 42 is connected to a vacuum pump P4. In the deaeratingmodule 4, the ink fed to the tube-like body 41 flows outside thehollow strings 42 so as to be deaerated. Specifically, the ink fed from thesecond ink tank 3 to the tube-like body 41 through asupply port 43 is sent to the center of the tube-like body 41; while being directed radially outwardly, the ink is brought into contact with the outer surface of eachhollow string 42, and air bubbles in the ink are thereby absorbed into the inside of eachhollow string 42. The deaerated ink is then fed to theprint head 5 from the tube-like body 41 via theoutlet 44. The pressure loss of the ink in the deaeratingmodule 4 is preferably 0.1 kPa or less. The vacuum pump P4 corresponds to a pressure-reducing means of the present invention. - The
print head 5 ejects the ink supplied from thesecond ink tank 3 via thedeaerating module 4 onto a print object. A known print head having a plurality of nozzles can be used. Between theprint head 5 and deaeratingmodule 4, two three-way valves V2 and V3, a pinch valve V4 provided between the three-way valves V2 and V3, and an ink booster pump P2 are disposed. The ink booster pump P2 is connected, via the three-way valves V2 and V3, to the flow path connecting to thedeaerating module 4 and theprint head 5. When printing is performed, the pinch valve V4 is in an open state, and the ink from thesecond ink tank 3 is supplied to theprint head 5 via the three-way valves V2 and V3, and the pinch valve V4, without passing through the ink booster pump P2. In contrast, in the event that the pressurized ink is supplied to the nozzles of theprint head 5 to prevent the nozzles of theprint head 5 from clogging, the pinch valve V4 is set to a closed state. Thereby, the ink from thesecond ink tank 3 is sent to the ink booster pump P2, via the three-way valves V2 and V3, which allows high-pressure ink to be supplied to the nozzles of theprint head 5 to forcibly discharge the ink from the nozzles, preventing the nozzles from clogging. The ink from the ink booster pump P2 is discharged to thesuction pad 6 described later. - As a means for eliminating clogging of the nozzles of the
print head 5, thesuction pad 6 and the suction pump P1 are provided. Thesuction pad 6 is provided so as to hermitically seal the nozzle portion of theprint head 5. When the suction pump P1 is operated while the nozzle portion of theprint head 5 is hermetically sealed with thesuction pad 6, the ink in the nozzles of theprint head 5 is forcibly suctioned to be discharged to thesuction pad 6. Thesuction pad 6 is removed from theprint head 5 when printing is performed. Because thesuction pad 6 covers the nozzles of theprint head 5, it also functions as a cap, preventing the ink within the nozzles from drying. Thesuction pad 6 is attached to an ink-dischargingtube 61. When an opening and closing means (not shown), such as an opening and closing valve, provided with the ink-dischargingtube 61 is set to a closed state, the ink within the nozzles of theprint head 5 is suctioned as described above. When the opening and closing means is set to an open state, only the ink within thesuction pad 6 is suctioned, while the ink within the nozzles of theprint head 5 is not suctioned. The flow path from thesuction pad 6 to thesecond ink tank 3 corresponds to the recycle flow path of the present invention. - The ink discharged to the
suction pad 6 is returned to thesecond ink tank 3 via afilter unit 7, a check valve V5, and the three-way valve V1. As the ink passes through thefilter unit 7, dust, etc., is removed from the ink. The check valve V5 is provided to prevent the ink from flowing in reverse. The check valve V5 prevents the ink fed from thefirst ink tank 2 to thesecond ink tank 3 from flowing into thefilter unit 7. When returning the ink discharged to thesuction pad 6 back to thesecond ink tank 3, the ink feed pump P3 is stopped. - The embodiments of the present invention are described above. However, the present invention is not limited thereto, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiments, two clogging prevention means, i.e., a suction means consisting of a
suction pad 6 and a suction pump P1, and a booster means consisting of an ink booster pump P2, are used as clogging prevention means of the nozzles of theprint head 5; however, it is possible for only one of the means to be used. -
