Definitions
- the present invention relates to a head cleaning device and an ink jet printer.
- the ink jet printer has a plurality of nozzles that eject ink. There are cases where dirt such as ink adheres to the ejection surface provided with the nozzle. For example, an ink jet printer that removes dirt on the discharge surface by a wiping member such as a wiper is known.
- the dirt on the wiper is removed by other members, for example.
- stains such as ink with increased viscosity may remain on the wiper.
- An example of a problem to be solved by the present invention is to provide a head cleaning device and an ink jet printer that can effectively clean a wiping member.
- a head cleaning device includes a storage tank, a wiping unit, and a cleaning unit.
- a cleaning liquid for cleaning the wiping unit is stored in the storage tank.
- the wiping unit has a wiping member for wiping the discharge surface. The cleaning unit cleans the wiping member in the cleaning liquid of the storage tank.
- the cleaning unit cleans the wiping member that wipes the ejection surface of the inkjet head using the cleaning liquid in the storage tank. Dirt adhering to the wiping member is taken into a large amount of cleaning liquid in the storage tank. As a result, the wiping member is effectively cleaned, and the dirt remaining on the wiping member is suppressed from adhering to the ejection surface of the inkjet head.
- the cleaning unit In the head cleaning apparatus, at least a part of the cleaning unit is immersed in the cleaning liquid in the storage tank, and the discharge surface and the wiping member come into contact with the discharge surface of the inkjet head and the wiping member. It is preferable to have a cleaning member for cleaning.
- the cleaning member cleans the ejection surface of the inkjet head and the wiping member. Thereby, the discharge surface and the wiping member are more effectively cleaned. If the discharge surface is wiped using a wiping member (for example, a wiper) while dirt such as ink remains attached to the discharge surface, the dirt may be pushed into the nozzle on the discharge surface, causing nozzle clogging. There is. Therefore, by cleaning the ejection surface of the ink jet head with the cleaning member, it is possible to suppress the occurrence of nozzle clogging due to dirt such as ink entering the nozzle. Furthermore, since one cleaning member cleans the ejection surface and the wiping member, the number of parts of the head cleaning device is reduced and the head cleaning device is saved in space.
- a wiping member for example, a wiper
- the wiping member has a contact portion that contacts the ejection surface of the inkjet head, and the contact portion is removed from the cleaning liquid in the storage tank when the wiping member wipes the ejection surface. It is preferably exposed and immersed in the cleaning liquid in the storage tank when the cleaning unit cleans the wiping member.
- the contact portion of the wiping member is immersed in the cleaning liquid in the storage tank when the cleaning unit cleans the wiping member. Thereby, the dirt adhering to the wiping member is taken into a large amount of cleaning liquid in the storage tank, and the wiping member is more effectively cleaned. Further, the contact portion of the wiping member is exposed from the cleaning liquid when the wiping member wipes the ejection surface of the inkjet head.
- the wiping member from which such dirt has been cleaned wipes the discharge surface, whereby the cleaning liquid remaining on the discharge surface cleaned by the cleaning unit is wiped off, and the discharge surface is easily dried. Thereby, the workability of cleaning the discharge surface is improved.
- the head cleaning device further includes an automatic level adjusting mechanism capable of changing the position of the liquid level of the cleaning liquid in the storage tank.
- the automatic level adjustment mechanism By changing the position of the liquid level of the cleaning liquid in the storage tank by the automatic level adjustment mechanism, when cleaning the discharge surface with the cleaning member, the contact position between the discharge surface and the cleaning member can be immersed in the cleaning liquid. Thereby, the discharge surface can be cleaned in the cleaning liquid, and the cleaning efficiency can be improved. Further, when wiping the discharge surface with the wiping member, the discharge surface can be reliably wiped by positioning the liquid surface of the cleaning liquid below the discharge surface. As described above, the position of the liquid surface of the cleaning liquid in the storage tank is changed by the automatic level adjustment mechanism, so that the cleaning of the discharge surface of the inkjet head using the cleaning member and the wiping member is performed more reliably. can do.
- the wiping unit includes a first position where the contact portion is exposed from the cleaning liquid in the storage tank, and a second position where the contact section is immersed in the cleaning liquid in the storage tank. It is preferable to have a first drive mechanism for moving the wiping member between the two.
- the first drive mechanism moves the wiping member between a first position where the contact portion is exposed from the cleaning liquid in the storage tank and a second position where the contact section is immersed in the cleaning liquid in the storage tank. Accordingly, the contact portion of the wiping member is immersed in the cleaning liquid without controlling the liquid level of the cleaning liquid. Furthermore, since the contact portion is moved to the second position by the first drive mechanism, the contact portion inadvertently contacts the ejection surface before being cleaned by the cleaning member, and the dirt remaining on the contact portion is inkjet. Adhering to the ejection surface of the head is suppressed.
- the head cleaning device further includes a control unit that controls the wiping unit so as to wipe the discharge surface after the cleaning member cleans the discharge surface.
- the cleaning surface and the dirt remaining on the discharge surface are removed by wiping the discharge surface with a wiping unit, thereby improving the cleaning effect of the discharge surface and making it easy to dry.
- the cleaning unit has a second drive mechanism that rotates or vibrates the cleaning member.
- the second drive mechanism rotates or vibrates the cleaning member.
- the discharge surface of the inkjet head and the wiping member are more effectively cleaned.
- the cleaning member at least partially immersed in the cleaning liquid in the storage tank rotates or vibrates, dirt transferred from the discharge surface and the wiping member to the cleaning member is taken into the cleaning liquid, and the cleaning member is cleaned.
- the second driving mechanism is magnetically coupled to the cleaning member via the wall of the storage tank and rotates or vibrates the cleaning member.
- the second drive mechanism is magnetically coupled to the cleaning member via the storage tank wall, and rotates or vibrates the cleaning member. For this reason, the cleaning member is rotated or vibrated without providing the second drive mechanism inside the storage tank or providing a member penetrating the wall of the storage tank. Therefore, the storage tank can be reduced in size, and the cleaning liquid can be prevented from leaking from the storage tank.
- An inkjet printer includes an inkjet head and the head cleaning device.
- the ink jet printer further includes a support member that supports the ink jet head and extends along a scanning direction.
- the ink jet head includes a scanning portion that ejects ink along the support member, and a scanning portion that is separated from the scanning portion. It is preferable that the head cleaning device cleans the ejection surface of the ink jet head located at the extension.
- the head cleaning device cleans the ejection surface of the inkjet head located at an extended portion that is out of the scanning portion that ejects ink. For this reason, the empty space of an inkjet printer is used effectively and an inkjet printer is reduced in size.
- the wiping member can be effectively cleaned.

- a motor or a solenoid valve included in the maintenance station 15 via a driver circuit, thereby replacing the cleaning liquid stored in the cap, or wiping the ejection surface 26 of the inkjet head 11 with a wiper.
- the wiper control unit 104 controls the second motor 88 of the wiping unit 81 via the driver circuit 118. That is, the wiper control unit 104 causes the driver circuit 118 to drive the second motor 88 to swing the wiper 83 between the exposure position P1 and the immersion position P2.
- the brush control unit 105 controls the first motor 61 via the driver circuit 62.
- the brush control unit 105 rotates the brush 51 as described above by causing the driver circuit 62 to drive the first motor 61.
- the storage tank position control unit 107 controls the actuator 45 via the driver circuit 114.
- the actuator 45 moves the storage tank 41 in the direction along the Z axis. That is, the storage tank position control unit 107 controls the position of the storage tank 41 in the Z direction.
- the controller 19 the head position control unit 101, the discharge control unit 102, the maintenance control unit 103, the wiper control unit 104, the brush control unit 105, the storage tank position control unit 107, and the like included therein are an arithmetic device, a memory, and the like Hardware and programs that realize these predetermined functions.
- FIG. 5 is a flowchart illustrating an example of the operation of the inkjet printer 10.
- the operation of the inkjet printer 10 described below is executed by, for example, a predetermined program.
- the inkjet printer 10 performs printing on the medium M in accordance with, for example, a print command from an external personal computer or an operation unit provided in the inkjet printer 10. That is, the inkjet printer 10 moves the carriage 12 and the bar 13 in the sub-scanning direction and the main scanning direction based on the print command.
- the inkjet head 11 ejects ink from the nozzles 23 to the medium M, whereby an image is formed on the medium M.
- the carriage 12 moves between the scanning part A1 and the extension parts A2 and A3 along the bar 13 during the printing.
- the carriage 12 moves from one extension portion A2 through the scanning portion A1 to the other extension portion A3.
- the carriage 12 that has reached the other extension portion A3 returns to the original extension portion A2 (standby position). That is, the carriage 12 reverses the moving direction at the extended portions A2 and A3.
- the maintenance station 15 and the cleaning station 16 face the ink jet head 11 located in empty spaces (extended portions A2 and A3) necessary for the reversal of the carriage 12, respectively. For this reason, the ink jet printer 10 can be reduced in size.
- the controller 19 determines whether or not it is time to clean the inkjet head 11 while the inkjet printer 10 is operating as during printing (step S11). For example, the controller 19 counts time with a timer, and when the counted time reaches a predetermined period, it determines that it is time to clean the inkjet head 11 (step S11: Yes). The period is, for example, half a day or a time when ink precipitation or condensation occurs. When it is determined that it is time to clean the inkjet head 11, the timer time count is reset.
- the controller 19 determines that it is time to perform the cleaning.
- cleans the inkjet head 11 is not restricted to this.
- the head position control unit 101 of the controller 19 controls the moving mechanism 112 to move the carriage 12 to the extended portion A3. In other words, the carriage 12 is moved onto the cleaning station 16 (step S12).
- the storage tank position control unit 107 controls the actuator 45 to raise the storage tank 41. Thereby, as shown in FIG. 3, the discharge surface 26 of the inkjet head 11 contacts the bristles 55 of the brush 51 (step S13).
- FIG. 6 is a cross-sectional view showing the inkjet head 11 and the cleaning station 16 in the brush cleaning process. As shown in FIG. 6, the hair 55 of the brush 51 contacts the ejection surface 26 of the moving inkjet head 11.
- the brush control unit 105 controls the brush drive mechanism 43 and the brush 51 is rotated.
- the brush 51 may be rotated only in the forward rotation direction, or may be rotated in the forward / reverse rotation direction by reversing the rotation direction at a predetermined cycle.
- the bristles 55 of the rotating brush 51 remove the dirt adhering to the ejection surface 26 of the inkjet head 11 (step S14).
- the portion exposed from the cleaning liquid L of the brush 51 rubs and cleans the ejection surface 26 of the inkjet head 11.
- the brush 51 winds up the cleaning liquid L by rotating. Thereby, the cleaning liquid L is bathed on the discharge surface 26 and the discharge surface 26 is cleaned. Furthermore, since a part of the brush 51 is immersed in the cleaning liquid L, the many hairs 55 of the brush 51 include the cleaning liquid L.
- the bristles 55 of the brush 51 containing the cleaning liquid L rub against the discharge surface 26 of the inkjet head 11, so that the discharge surface 26 is effectively cleaned.
- the discharge surface 26 may be immersed in the cleaning liquid L.
- the concentration of ink attached to the discharge surface 26 is reduced.
- the brush 51 effectively rubs the discharge surface 26 by rubbing the discharge surface 26 while being immersed in the cleaning liquid L.
- the wiper 83 is basically disposed at the immersion position P2. For this reason, the bristles 55 of the rotating brush 51 rub the tip 83b of the wiper 83 in the cleaning liquid L to remove the dirt adhering to the tip 83b. Dirt on other parts of the wiper 83 is also removed by the cleaning liquid L. Further, the wiper 83 does not contact the moving inkjet head 11. Thus, when the brush 51 cleans the wiper 83, the wiper 83 is immersed in the cleaning liquid L in the storage tank 41.
- the dirt on the ejection surface 26 of the inkjet head 11 and the dirt on the tip 83b of the wiper 83 removed by the brush 51 are taken into the cleaning liquid L. That is, even if dirt adheres to the hair 55 of the brush 51, the brush 51 rotates in the cleaning liquid L, so that the dirt on the hair 55 is removed by the cleaning liquid L.
- FIG. 7 is a bottom view showing the carriage 12 and the brush 51.
- the entire ejection surface 26 can be cleaned by making the length of the brush 51 (the dimension along the X axis) larger than the length of the inkjet head 11.
- the width (diameter, dimension along the Y axis) of the brush 51 may be smaller than the width of the inkjet head 11 and can be reduced in size.
- the length of the wiper 83 the dimension along the X axis
- the width of the wiper 83 (the dimension along the Y axis) may be smaller than the width of the inkjet head 11 and can be downsized.
- FIG. 8 is a cross-sectional view showing the inkjet head 11 and the cleaning station 16 in the wiping process.
- the wiper control unit 104 controls the second motor 88 to move the wiper 83 to the exposure position P1.
- the tip 83b of the wiper 83 is exposed from the surface of the cleaning liquid L.
- the head position control unit 101 controls the moving mechanism 112 to move the inkjet head 11 in the direction along the Y axis.
- the tip 83b of the wiper 83 contacts the ejection surface 26 of the moving inkjet head 11.
- the tip 83b of the wiper 83 removes the cleaning liquid L and dirt remaining on the ejection surface 26 by wiping the ejection surface 26 of the moving inkjet head 11 (step S16). Thereby, the discharge surface 26 is cleaned and easily dried.
- the controller 19 controls the head position control unit 101 and the wiper control unit 104 to thereby control the discharge surface 26 by the wiper 83. Control is performed to perform wiping (step S16).
- the controller 19 is an example of a control unit.
- the head position control unit 101 controls the moving mechanism 112 to move the carriage 12 to the extension portion A2 (standby position) (step S17).
- the cleaning of the inkjet head 11 by the cleaning station 16 is completed.
- step S11 determines whether it is time to perform maintenance of the inkjet head 11 (step S18). For example, the controller 19 counts time with another timer, and when the counted time reaches a predetermined period, it determines that it is time to perform maintenance of the inkjet head 11 (step S18: Yes). The period is shorter than the period for determining the timing for cleaning the inkjet head 11. If it is determined that it is time to perform maintenance of the inkjet head 11, the timer count is reset.
- the controller 19 may determine that it is time to perform maintenance of the inkjet head 11 when it is determined that the viscosity of the ink inside the inkjet head 11 has reached a predetermined viscosity of about 20 millipascal seconds or less.
- standard judged that it is a timing which performs the maintenance of the inkjet head 11 is not restricted to this.
- the ejection control unit 102 of the controller 19 controls the drive element 24 in a state where the carriage 12 is in the extended portion A ⁇ b> 2 (standby position). Is vibrated slightly (step S19).
- the driving element 24 raises or lowers the pressure of the ink in the pressure chamber 22, but the ink is not ejected from the nozzle 23. Due to the minute vibration, the ink meniscus in the nozzle 23 vibrates, and the drying and viscosity increase of the ink in the vicinity of the nozzle 23 are suppressed.
- the minute vibration of the drive element 24 is not limited to during maintenance, but may be always performed during operation of the inkjet printer 10.
- the ejection control unit 102 controls the drive element 24 to perform flushing for ejecting ink from the nozzles 23 (step S20).
- the ink is discharged from the nozzle 23 to the cleaning liquid for the cap of the maintenance station 15.
- ink whose viscosity has increased due to drying in the vicinity of the nozzle 23 is discharged, and clogging of the nozzle 23 and flying bending of ink droplets are suppressed.
- the maintenance control unit 103 wipes the ejection surface 26 of the inkjet head 11 with the wiper of the maintenance station 15 (step S21). Thereby, dirt such as ink and dust attached to the ejection surface 26 is removed.
- the maintenance station 15 may select and perform at least one of micro vibration (step S19), flushing (step S20), and wiping (step S21).
- the maintenance station 15 may suck the cleaning liquid for the cap from the nozzle 23 on the ejection surface 26 of the inkjet head 11 covered with the cap. As a result, ink and stains with increased viscosity inside the inkjet head 11 are removed.
- the controller 19 repeats the cleaning (steps S11 to S17) and the maintenance (steps S18 to S21) of the inkjet head 11 until the operation of the inkjet printer 10 is completed (step S22). Thereby, the inkjet head 11 is kept clean and maintains the printing quality.
- the precipitation of the ink pigment in the ink tube is performed by providing an annular flow path between the damper 31 and the ink tank to circulate the ink. It is suppressed. The occurrence of contamination in the damper 31 is suppressed by flushing (step S20) in the maintenance station 15.
- Occurrence of contamination on the ejection surface 26 of the inkjet head 11 is suppressed by brush cleaning (step S14) in the cleaning station 16.
- the thickening of the ink meniscus at the nozzle 23 is suppressed by flushing at the maintenance station 15 (step S20).
- the occurrence of dirt or the like that may cause a printing failure of the inkjet head 11 is suppressed by the maintenance station 15 and the cleaning station 16.
- the ink jet head 11 is effectively maintained by combining the maintenance station 15 and the cleaning station 16.
- the cleaning unit 42 uses the cleaning liquid L in the storage tank 41 to clean the wiper 83 that wipes the ejection surface 26 of the inkjet head 11.
- the dirt adhering to the wiper 83 is taken into a large amount of the cleaning liquid L in the storage tank 41.
- the wiper 83 is effectively cleaned, and dirt remaining on the wiper 83 is suppressed from adhering to the ejection surface 26 of the inkjet head 11.
- the brush 51 may be vibrated by the brush drive mechanism 43.
- the brush 51 rubs and cleans the ejection surface 26 of the inkjet head 11 by vibrating.
- the method of cleaning by bringing the brush 51 into contact with the ejection surface 26 as in the first embodiment described above is particularly effective when either emulsion ink or ultraviolet curable ink is ejected from the ejection surface 26 as ink.
- Emulsion ink and ultraviolet curable ink once cured, have high weather resistance and are difficult to remove by subsequent washing.
- the ink is not sufficiently cleaned on the discharge surface of the ink jet head and is cured while adhering to the discharge surface, it is difficult to remove the ink from the discharge surface even by subsequent cleaning. Therefore, it is important that the cleaning of the ejection surface of the inkjet head is performed properly at an appropriate time.
