[Cleaning device]
Next, the configuration of the cleaning device 30 will be explained. FIG. 4 is a perspective view showing the cleaning device 30. FIG. 5 is a block diagram showing the electrical configuration of the cleaning device 30. As shown in FIG. 6 and 7 are front views showing how the inkjet head 12 slides.

The cleaning device 30 according to the present embodiment includes a feeding section 33 that feeds out a band-shaped wiping member 32, a winding section 34 that winds up the wiping member 32, and a winding section 34 that feeds out the wiping member 32 containing cleaning liquid. A pressing part 35 that presses against the nozzle surface 12F of the inkjet head 12 between the supporting body 31 that supports the feeding part 33, the winding part 34, and the pressing part 35, and the inkjet head 12. A slide mechanism 41 that slides in a direction along the direction, a cleaning liquid supply section 37 that supplies cleaning liquid to the wiping member 32 on the upstream side of the pressing section 35 in the direction in which the wiping member 32 is fed, and between the pressing section 35 and the winding section 34. A cleaning liquid collecting section 51 is provided, which collects the cleaning liquid from the wiping member 32 and supplies the collected cleaning liquid to the wiping member 32 between the feeding section 33 and the pressing section 35. Specifically, it is as follows.

One cleaning device 30 is provided for each inkjet head 12. As shown in FIG. 4, when cleaning the inkjet head 12, it is necessary to arrange the cleaning device 30 below the inkjet head 12. It is required that the cleaning of the inkjet head 12 can be performed at any time, for example, when the operating time of the inkjet recording apparatus 1 after the previous cleaning reaches a predetermined time, or when a decrease in image quality is observed. However, a platen 7 (see FIG. 1) is provided below the image forming unit 6. A configuration in which the cleaning device 30 is moved to the space below the image forming unit 6 by moving the platen 7 forward, backward, left, right, or downward may also be considered, but cleaning may be performed while the sheet S is stopped on the platen 7. When it becomes necessary, it becomes necessary to remove the sheet S. However, since it is inefficient to remove the sheet S every time cleaning is performed, it is desirable to be able to clean the sheet S without removing it.

An example of a configuration in which cleaning can be performed without removing the sheet S is to provide a cleaning device 30 on the left or right side of the platen 7 and a mechanism that slides the image forming unit 6 above the cleaning device 30. is possible. Alternatively, the cleaning device 30 may be provided on either the front, rear, left or right sides of the image forming unit 6, and a mechanism for raising and lowering the image forming unit 6 and a mechanism for sliding the cleaning device 30 below the raised image forming unit 6 may be provided.

The cleaning device 30 includes a rectangular parallelepiped-shaped support 31 whose longitudinal direction is the left-right direction. A portion corresponding to the upper surface of the rectangular parallelepiped is open. The support body 31 is provided with a feeding section 33, a winding section 34, a pressing section 35, and a cleaning liquid recovery section 51. The support body 31 is a frame-shaped member that surrounds the lower part and the sides of the feeding part 33 and the like. Since the support body 31 has a frame shape, the possibility that the cleaning liquid will scatter to other parts of the inkjet recording apparatus 1 can be reduced. Further, since volatilization of the cleaning liquid from the wiping member 32 is suppressed, the amount of cleaning liquid contained in the wiping member 32 can be maintained at an appropriate level.

[Feeding part, wiping member]
The feeding portion 33 is provided at the lower right portion of the support body 31. The feeding portion 33 includes a shaft 33S whose axial direction is the front-rear direction.

The shaft 34S is provided with a drive unit (not shown) including a motor, a reduction gear, and the like. The wiping member 32 fed out from the feeding section 33 is wound around the shaft 34S.

[Press part]
The pressing section 35 is provided above the support body 31 and to the left of the winding section 34 . The pressing part 35 is a driven roller whose front and rear ends are supported by the support body 31. The pressing portion 35 includes a shaft and an elastic layer formed around the shaft using silicone rubber or the like. The upper part of the elastic layer is exposed from the support 31. The pressing portion 35 is pressed against the nozzle surface 12F by being biased upward by, for example, a compression coil spring (not shown).

[Slide mechanism]
The slide mechanism 41 (see FIG. 5) slides the support 31 or the image forming unit 6 along the nozzle surface 12F in the longitudinal direction (horizontal direction) of the nozzle surface 12F. Specifically, as described above, the cleaning device 30 may be provided on the left or right side of the platen 7, and the slide mechanism 41 for sliding the image forming unit 6 above the cleaning device 30 may be provided. Alternatively, the cleaning device 30 is provided on either the front, rear, left or right sides of the image forming unit 6, and a mechanism for raising and lowering the image forming unit 6 and a slide mechanism 41 for sliding the cleaning device 30 below the raised image forming unit 6 are provided. You can. Regarding the latter, the 12 cleaning devices 30 may be formed into a unit, but the four head units 11 may be arranged at intervals, and the three cleaning devices 30 may be formed into a unit before or after each head unit 11. They may be placed next to each other. As the slide mechanism 41, for example, a mechanism in which an endless belt is driven by a pulley, a rack and pinion, a feed screw, a ball screw, or the like is used.

[Cleaning liquid recovery section]
The cleaning liquid recovery section 51 is provided at the lower left of the winding section 34. The cleaning liquid recovery section 51 includes a pair of rollers 52 facing each other in the vertical direction. The position of one roller of the roller pair 52 is fixed, and the other roller is biased toward the one roller with a predetermined load by a compression coil spring (not shown) or the like. The cleaning liquid recovery section 51 squeezes out the mixture of cleaning liquid and residual ink contained in the wiping member 32.

[guide roller]
The guide rollers 45, 46, and 47 are provided on the lower left side of the support body 31, on the left side of the pressing part 35, and on the right side of the pressing part 35, respectively. The wiping member 32 fed out from the feeding part 33 is wound around a guide roller 45, a guide roller 46, a pressing part 35, a guide roller 47, a cleaning liquid recovery part 51 in this order, and finally wound up by a winding part 34.

The cleaning liquid recovery section 51 is arranged on the lower right side of the guide roller 47. Therefore, the path 53 of the wiping member 32 from the upstream side in the feeding direction of the wiping member 32 to the cleaning liquid recovery section 51 has a downward slope. Further, the cleaning liquid recovery section 51 is arranged at the lower left of the winding section 34. Therefore, the path 54 of the wiping member 32 from the cleaning liquid recovery section 51 to the downstream side in the feeding direction of the wiping member 32 has an upward slope.

[Cleaning liquid supply section]
Either one of the guide rollers 45 and 46 also serves as the cleaning liquid supply section 37. Specifically, the cleaning liquid supply unit 37 is, for example, a driven roller, has a hollow structure, and is provided with a large number of fine holes penetrating in the radial direction (not shown). The inside of the cleaning liquid supply section 37 is filled with cleaning liquid. As the wiping member 32 is drawn out, the cleaning liquid supply section 37 rotates, and the cleaning liquid seeping out from the hole permeates into the wiping member 32. When the ink is a water-based ink, the main component of the cleaning liquid is water. A surfactant or the like may be added to the cleaning liquid.

Next, the operation of the cleaning device 30 will be explained (see FIGS. 6 and 7). The control section 2 controls the feeding section 33, the winding section 34, and the slide mechanism 41 to execute the following processing. Note that, as described above, the slide mechanism 41 slides the support body 31 or the image forming unit 6, but here, as an example, the cleaning device 30 is provided on the right side or the right side of the platen 7, and the image forming unit 6 The case of sliding in the left and right direction will be explained. Note that since the 12 inkjet heads 12 included in the image forming unit 6 slide together, only one inkjet head 12 is illustrated here, and the image forming unit 6 can be read as the inkjet head 12. explain.

First, the control section 2 operates the feeding section 33 and the winding section 34 to feed out the unused portion of the wiping member 32 by a predetermined length. At this time, the cleaning liquid is supplied from the cleaning liquid supply section 37 to the wiping member 32 .

Next, the control unit 2 operates the slide mechanism 41 to slide the inkjet head 12 located above the platen 7 above the cleaning device 30 (see FIG. 6). The control section 2 stops the slide when the left end of the nozzle surface 12F reaches the pressing section 35 (see FIG. 7). By this sliding action, the pressing portion 35 wipes off the residual ink that the cleaning liquid has permeated from the nozzle surface 12F. At this time, the drawing out of the wiping member 32 may be stopped, but the drawing out of the wiping member 32 may be continued. However, if the sliding speed of the inkjet head 12 and the feeding speed of the wiping member 32 are equal, wiping cannot be performed, so it is necessary to make the sliding speed and feeding speed different.

Finally, the control unit 2 slides the inkjet head 12 above the platen 7. Since the residual ink is removed from the nozzle surface 12F, disturbances in ink ejection are suppressed, and a high-quality image is formed.

The wiping member 32 is fed out at the above-mentioned timing, and in that case, the cleaning liquid collection section 51 collects the cleaning liquid containing the residual ink from the wiping member 32. The collected cleaning liquid falls onto the wiping member 32 below the cleaning liquid recovery section 51 and is absorbed by the wiping member 32.

According to the cleaning device 30 according to the present embodiment described above, the feeding section 33 that feeds out the strip-shaped wiping member 32, the winding section 34 that winds up the wiping member 32, and the feeding section 33 that feeds out the wiping member 32 containing cleaning liquid. A pressing part 35 that presses against the nozzle surface 12F of the inkjet head 12 between the winding part 34 and the supporting body 31 that supports the feeding part 33, the winding part 34, and the pressing part 35, and the inkjet head 12. A slide mechanism 41 that slides the cleaning liquid in the direction along the nozzle surface 12F, a cleaning liquid supply section 37 that supplies cleaning liquid to the wiping member 32 on the upstream side of the pressing section 35 in the feeding direction of the wiping member 32, and a cleaning liquid supplying section 37 that supplies cleaning liquid to the wiping member 32 from the pressing section 35 and the winding mechanism. A cleaning liquid recovery section 51 is provided, which collects the cleaning liquid from the wiping member 32 between the feeding section 33 and the pressing section 35 and supplies the recovered cleaning liquid to the wiping member 32 between the feeding section 33 and the pressing section 35 . According to this configuration, since the used cleaning liquid is reused, the consumption amount of the cleaning liquid can be suppressed.

Further, according to the cleaning device 30 according to the present embodiment, the cleaning liquid recovery unit 51 is provided above the wiping member 32 between the feeding unit 33 and the pressing unit 35, and drops the collected cleaning liquid onto the wiping member 32. . According to this configuration, the collected cleaning liquid can be supplied to the wiping member 32 with a simple configuration. Moreover, energy consumption can be suppressed.

Further, according to the cleaning device 30 according to the present embodiment, the cleaning liquid recovery section 51 includes a pair of rollers 52 that sandwich the wiping member 32 and squeeze out the cleaning liquid. According to this configuration, the cleaning liquid can be recovered with a simple configuration.

Moreover, according to the cleaning device 30 according to the present embodiment, the path 53 of the wiping member 32 from the upstream side in the feeding direction of the wiping member 32 to the cleaning liquid recovery section 51 has a downward slope. According to this configuration, it is possible to prevent the collected cleaning liquid from seeping into the upstream portion of the wiping member 32.

Further, according to the cleaning device 30 according to the present embodiment, the path 54 of the wiping member 32 from the cleaning liquid recovery section 51 to the downstream side in the direction of delivery of the wiping member 32 has an upward slope. According to this configuration, it is possible to prevent the collected cleaning liquid from seeping into the downstream portion of the wiping member 32.

The above embodiment may be modified as follows.

FIG. 8 is a front view showing a cleaning device 30 according to a modification of the above embodiment. The cleaning device 30 includes a water tank 57 below the cleaning liquid recovery section 51 , and a path 58 of the wiping member 32 between the feeding section 33 and the pressing section 35 passes through the inside of the water tank 57 . According to this configuration, the cleaning liquid F that was not completely absorbed by the wiping member 32 after falling onto the wiping member 32 can be stored and reused.

Further, the cleaning liquid recovery section 51 cannot recover all of the cleaning liquid F contained in the wiping member 32, and it is considered that some cleaning liquid F remains in the wiping member 32 after the cleaning liquid F has been collected. By storing a predetermined amount of cleaning liquid F in the water tank 57 in advance, the stored cleaning liquid F is supplied to the wiping member 32. According to this configuration, the cleaning liquid F remaining on the wiping member 32 after the cleaning liquid F has been collected can be supplemented. In this case, since the water tank 57 also has the function of the cleaning liquid supply section 37, the cleaning liquid supply section 37 shown in the above embodiment may not be provided.

In addition to the configuration of the above embodiment, the inkjet recording apparatus 1 may include a wipe unit that scrapes off residual ink by sliding a resin blade pressed against the nozzle surface 12F (not shown). By using this configuration together with wiping by the wiping member 32 shown in the above embodiment, residual ink can be removed more reliably. Alternatively, since the blade has lower frictional resistance against the nozzle surface 12F than the wiping member 32, the residual ink can be scraped off with the blade after the cleaning liquid has penetrated into the residual ink using the procedure of the above embodiment. It can extend the lifespan.

In the embodiment described above, an example is shown in which the driving section is provided in the feeding section 33, but a torque limiter (not shown) may be provided instead of the driving section. With this configuration as well, the wiping member 32 can be fed out while maintaining tension.

In the above embodiment, an example is shown in which the pressing part 35 is a driven roller, but the pressing part 35 may be a member that does not rotate.

In the above embodiment, as an example of the cleaning liquid supply section 37, a configuration in which the cleaning liquid oozes out from the hole of the driven roller is shown, but the cleaning liquid supply section 37 is provided between the feeding section 33 and the pressing section 35 to the wiping member 32. The cleaning liquid may be configured to drip from above. Alternatively, the cleaning liquid supply section 37 may be configured to spray the cleaning liquid onto the wiping member 32 between the feeding section 33 and the pressing section 35. Alternatively, the cleaning liquid supply unit 37 may be configured to immerse the wiping member 32 in a water tank in which cleaning liquid is stored between the feeding unit 33 and the pressing unit 35. Alternatively, the cleaning liquid supply unit 37 may be configured to immerse the lower part of the wiping member 32 wound around the feeding unit 33 in a water tank storing cleaning liquid (both are not shown).

In the above embodiment, an example of the inkjet recording apparatus 1 that prints on a roll sheet S is shown, but the present invention may be applied to an inkjet recording apparatus that prints on a single sheet.
