<Outline of inkjet recording device (Figs. 1 and 2)>
FIG. 1 is a perspective view schematically showing an internal configuration of an inkjet recording device 1 (hereinafter, recording device 1) according to an embodiment. FIG. 2 is a cross-sectional view of the side surface of the recording device 1 of FIG.

The recording device 1 is a device that ejects ink as a liquid to a recording medium 3 as a medium to perform recording. The recording device 1 includes a housing 10, a paper feeding unit 21, a transport roller 22, a pinch roller 23, a platen 24, a recording unit 40, a paper ejection roller 25, and a spur 26 provided in the housing 10.

The paper feeding unit 21 feeds the recording medium 3 into the housing 10. For example, the paper feed unit 21 includes a paper feed cassette 211 capable of loading the recording medium 3 and a paper feed roller 212 for transporting the recording media 3 loaded on the paper feed cassette 211 one by one into the housing 10. ..

The transfer roller 22 and the pinch roller 23 driven by the transfer roller 22 convey the recording medium 3 conveyed by the paper feed roller 212 further downstream. The transport roller 22 and the pinch roller 23 come into contact with each other to form a nip portion. When the recording medium 3 reaches the nip portion, it is further conveyed by the rotational drive of the transfer roller 22 and the gripping of the pinch roller 23. For example, the rotational driving force of the transfer motor (not shown) is transmitted to the transfer roller 22 via the transfer drive row (not shown), so that the transfer roller 22 rotates and the recording medium 3 is conveyed.

The platen 24 supports the recording medium 3 on the lower side of the transport roller 22 on the downstream side in the transport direction. In other words, the platen 24 forms a transport path for the recording medium 3. The platen 24 is provided so as to face the ink ejection surface of the recording head 41. Further, the platen 24 is formed with a plurality of openings 241 through which ink droplets on the upper side of the platen 24 pass under the platen 24.

Further, in the present embodiment, the recording device 1 includes an absorbing member 5 provided on the platen 24 (see FIG. 3). The absorbing member 5 is supported by the platen 24 from below so as to cover the opening 241 formed in the platen 24. The absorbing member 5 is a member capable of absorbing ink droplets ejected from the recording head 41 and not landing on the recording medium 3. For example, the absorbing member 5 absorbs ink droplets ejected to the outside of the recording medium 3 during so-called rimless recording, ink droplets ejected from the recording head 41 during preliminary ejection as a maintenance operation of the recording head 41, and the like. do. Further, for example, the absorbing member 5 may be made of a material capable of absorbing and holding a liquid, such as urethane foam having good ink absorption and permeability.

The ink absorbed by the absorbing member 5 is dropped onto the flow path forming portion 6 through the opening 241 of the platen 24, and passes through the flow path formed by the flow path forming portion 6 to the waste liquid tank 8 (accommodating portion). Moving. These configurations will be described more specifically in <Recovery of Waste Liquid (FIGS. 3 to 6)>.

The recording unit 40 records on the recording medium 3. The recording unit 40 includes a recording head 41 capable of ejecting ink to the recording medium 3 and a carriage 42 capable of reciprocating the recording head 41 in the scanning direction. The scanning direction is a direction orthogonal to the transport direction of the recording medium 3. The recording head 41 can, for example, eject inks of four colors of C (cyan), M (magenta), Y (yellow), and K (black) from the respective nozzle rows. The number of colors of ink ejected by the recording head 41 can be appropriately set. For example, the driving force of a carriage motor (not shown) is transmitted to the carriage 42 via the timing belt 44. When the driving force is transmitted, the carriage 42 reciprocates in the scanning direction while being guided by the carriage rail 43. The recording head 41 may be a line head in which a nozzle row is arranged in an area corresponding to the width of the recording medium 3.

When the recording medium 3 is conveyed to the recording position facing the recording head 41 by the conveying roller 22 and the pinch roller 23, the recording head 41 ejects ink while the carriage 42 is moving in the scanning direction. Images are recorded on the recording medium 3 in the transport direction by repeating the transport of the recording medium 3 by the transport roller 22 and the recording operation by the recording unit 40.

Here, in the case of recording to the edge without leaving a margin on the recording medium 3, that is, in the case of so-called borderless recording, ink is ink from the recording head 41 outside the edge of the recording medium 3 in the paper width direction. Drops will be ejected. The ink droplets ejected to the outside of the recording medium 3 are absorbed by the absorption member 5 described above.

The recording medium 3 recorded by the recording unit 40 is conveyed by the transfer roller 22 and the pinch roller 23 to the paper ejection roller 25 and the spur 26 arranged on the downstream side in the transfer direction of the platen 24.

The spur 26 driven by the paper ejection roller 25 and the paper ejection roller 25 discharges the recording medium 3 to the outside of the housing 10. The paper ejection roller 25 and the spur 26 abut against each other to form a nip portion. When the recording medium 3 reaches the nip portion, it is conveyed to the outside of the housing 10 by the rotational drive of the paper ejection roller 25 and the gripping of the spur 26. For example, the rotational driving force of the transfer motor (not shown) is transmitted through the transfer drive row (not shown), so that the paper ejection roller 25 rotates and the recording medium 3 is conveyed. A paper ejection tray 27 is arranged on the downstream side of the paper ejection roller 25 in the transport direction, and the recording medium 3 for which recording has been completed is ejected and loaded on the paper ejection tray 27.

<Recovery of waste liquid (Figs. 3 to 6)>
The collection of ink discharged from the recording head 41 and not landing on the recording medium 3 (hereinafter, may be referred to as waste liquid or waste ink) will be described. FIG. 3 is a front sectional view for explaining the recovery of the waste liquid. FIG. 4 is a side sectional view taken along the line AA in FIG. 3 for explaining the recovery of the waste liquid. FIG. 5 is a top view for explaining the recovery of the waste liquid. FIG. 6 is an exploded perspective view illustrating the recovery of the waste liquid.

Briefly, the ink that has not landed on the recording medium 3 is absorbed by the absorbing member 5 arranged on the platen 24 as waste ink. After that, the waste ink exuded from the absorbing member 5 is dropped onto the flow path forming portion 6, and is collected by the waste liquid tank 8 for accommodating the waste liquid through the flow path formed by the flow path forming portion 6. Hereinafter, each configuration related to the recovery of waste liquid will be specifically described.

(Absorbent member 5 and platen 24)
The absorbing member 5 is provided on the platen 24 as described above. The absorbing member 5 includes a main body 51 that absorbs waste ink, and a hanging portion 52 that extends downward in the vertical direction from the main body 51. In the present embodiment, the absorbing member 5 is provided so as to pass through the opening 241 of the platen 24 and extend to the lower side of the platen 24. The waste ink absorbed by the main body 51 collects in the hanging portion 52 provided below the main body 51 due to the action of gravity. Then, when an amount of waste ink exceeding the ink holding capacity of the hanging portion 52 is collected in the hanging portion 52, the waste ink seeps out from the lower side in the vertical direction of the hanging portion 52, and the waste ink is dropped to the lower side in the vertical direction. That is, the waste ink moves from the upper side to the lower side of the platen 24 through the opening 241 by the absorbing member 5. The waste ink dropped from the hanging portion 52 is dropped on the flow path forming portion 6 arranged below the platen 24. Further, the opening 241 is formed above the inclined portion 60 of the flow path forming portion 6, which will be described later, and the waste ink dropped from the hanging portion 52 is dropped onto the inclined portion 60.

It is also possible to adopt a configuration in which the absorbing member 5 is not arranged on the platen 24. In this case, the waste ink that has landed on the platen 24 is guided to the opening 241 provided vertically downward with respect to the other portion, and the waste ink is dropped vertically downward through the opening 241. ..

Further, in order to promote the dropping of waste ink, the opening 241 of the platen 24 is located near the end of the recording medium 3 where the ink is likely to land during rimless recording, or near the edge where the preliminary ejection is performed during the maintenance operation of the recording head 41. It may be provided. Further, the number of the hanging portions 52 and the openings 241 can be appropriately set.

It should be noted that a configuration in which the ink droplets are directly supplied to the flow path forming portion 6 without going through the platen 24 can also be adopted. Further, it is also possible to adopt a configuration in which the flow path forming portion 6 is arranged on the platen 24 or in which these are integrated, and in that case, the waste ink may be directly dropped onto the flow path forming portion 6.

(Flow path forming portion 6)
The flow path forming portion 6 defines a flow path of the liquid discharged from the recording head 41 and not landing on the recording medium 3. The flow path forming portion 6 is formed of, for example, a resin material. In the present embodiment, the flow path forming portion 6 is formed integrally with the bottom portion 11 of the housing 10 below the platen 24. However, the flow path forming portion 6 may be formed of a component different from the housing 10 and may be attached to the housing 10. The flow path forming portion 6 includes an inclined portion 60 and an inclined portion 73.

((Inclined portion 60))
The inclined portion 60 is inclined downward toward a predetermined position so as to define a flow path for directing the liquid ink droplet to the predetermined position 65. In the present embodiment, the flow path forming portion 6 includes two inclined portions 60a and 60b. Hereinafter, when the matters common to the inclined portions 60a and 60b are described, these may be collectively referred to as the inclined portion 60. The same applies to the components of the inclined portions 60a and 60b.

The inclined portion 60 defines a flow path 600 as a flow path for directing ink droplets to a predetermined position 65. Further, in the present embodiment, the inclined portion 60 is inclined downward from the outside to the inside (center) of the recording device 1 in the scanning direction. Therefore, the flow path 600 directs the ink droplet to a predetermined position 65 inside in the scanning direction. That is, the flow direction of the flow path 600 includes a component in the width direction of the recording medium 3 orthogonal to the transport direction of the recording medium 3.

Further, in the present embodiment, the inclined portion 60 includes side walls 61 and 62 (both side walls) forming a valley-shaped slope in the width direction of the flow path 600. The side walls 61 and 62 are arranged so as to extend so that the scanning direction of the recording unit 40 is the longitudinal direction, respectively. Further, the side walls 61 and 62 form a valley-shaped slope due to the inclination in the lateral direction. The angle and length of the slope formed by the side walls 61 and 62 can be appropriately set, and may be the same or different from each other. Further, the angle of the slope formed by the side walls 61 and 62 is not constant but may change over the flow direction or the width direction of the flow path 600. Further, the slope formed by the side walls 61 and 62 is not limited to one plane, and may be configured by connecting a plurality of planes or may include a curved surface. Further, in the present embodiment, the side walls 61 and 62 are formed with slopes as a whole, but the side walls 61 and 62 may include a portion forming a horizontal or vertical surface. That is, the shape of the valley-shaped slope formed by the side walls 61 and 62 is not limited, and may be formed so that ink droplets can be collected inside the flow path 600 in the width direction.

Further, in the present embodiment, the inclined portion 60 includes a bottom portion 71 provided so as to connect both lower edges of the side walls 61 and 62. The bottom portion 71 is provided so as to extend in the scanning direction along the longitudinal direction of the side walls 61 and 62. In this embodiment, the bottom portion 71 is formed in the shape of a rectangular groove. The shape of the groove formed by the bottom portion 71 is not limited to a rectangular shape, and may be a U-shape, a semicircular shape, or the like. Further, the bottom portion 71 may connect both lower edge portions of the side walls 61 and 62 substantially horizontally without forming a groove.

In other words, regarding the structure of the side walls 61 and 62, it can be said that the normal of the slope formed by the side walls 61 and 62 has an inclination with respect to the vertical direction. Further, when the slopes formed by the side walls 61 and 62 are virtually extended, it can be said that the line segment connecting the points where they intersect has an inclination with respect to the horizontal direction.

Here, as described above, in the present embodiment, the flow path forming portion 6 includes two inclined portions 60a and 60b. The inclined portion 60a is inclined downward toward the predetermined position 65 so as to define a flow path 600a for directing the ink droplet to the predetermined position 65. Further, the inclined portion 60b is inclined downward toward the predetermined position 65 so as to define a flow path 600b for directing the ink droplet to the predetermined position 65. That is, the inclined portions 60a and 60b define the flow paths 600a and 600b so as to direct the ink droplets to the common predetermined position 65, respectively. In other words, it can be said that the predetermined position 65 is the confluence point of the flow path 600a and the flow path 600b at the predetermined position 65. In the present embodiment, the predetermined position 65, which is the confluence of the flow paths 600a and 600b, is arranged at the center position of the recording device 1 in the width direction of the recording medium 3. Further, the predetermined position 65 is formed in a region surrounded by both lower ends of the side walls 61a and 62a of one inclined portion 60a and both lower ends of the side walls 61b and 62b of the other inclined portion 60b.

Further, the two inclined portions 60a and 60b are arranged so as to face each other with the predetermined position 65 interposed therebetween. More specifically, the inclined portions 60a and 60b are arranged so that the flow paths 600a and 600b formed by them are defined at predetermined positions 65 on the same straight line in the scanning direction. As a result, the inclined portion 60 can be miniaturized in the transport direction.

Further, the side walls 61a and 62a of the inclined portion 60a and the side walls 61b and 62b of the inclined portion 60b are provided so as to intersect at substantially one point of intersection when the slope formed by them is virtually extended. Further, the side walls 61a, 62a, 61b, and 62b are arranged so that the positions closest to the lowermost side in the vertical direction of the slopes formed by the side walls 61a, 62a, 61b, and 62b are the intersections.

(((Inclined portion 73))
The inclined portion 73 is inclined downward toward the waste liquid tank 8 so that the flow path forming portion 6 defines the flow path 730 for directing the liquid from the predetermined position 65 to the waste liquid tank 8 containing the waste liquid. In the present embodiment, the inclined portion 73 is formed in a groove shape having an inclined bottom surface. The waste ink that has passed through the flow path 730 is introduced into the waste liquid tank 8 from the discharge portion 75 at the downstream end of the flow path 730. The groove shape of the inclined portion 73 can be appropriately set.

Further, in the present embodiment, the inclined portion 73 is formed so that the flow direction of the flow path 730 includes a component in the transport direction of the recording medium 3. Further, the inclined portion 73 is formed so that the horizontal component in the flow direction of the flow path 730 is parallel to the transport direction of the recording medium 3. Therefore, the ink droplets that have reached the predetermined position 65 can reach the waste liquid tank 8 in the shortest distance. Therefore, since the inclined portion 73 can be shortened in the transport direction of the recording medium 3 and the height of the inclined portion 73 can be lowered, it is possible to reduce the size of the apparatus and increase the size of the waste liquid tank 8. Further, the waste liquid tank 8 can be arranged near the flow path forming portion 6.

((Waste liquid tank 8))
The waste liquid tank 8 stores waste liquid (waste ink). In the present embodiment, the waste liquid tank 8 is detachably provided with respect to the housing 10 of the recording device 1. Further, the waste liquid tank 8 contains an absorbing member 81 capable of absorbing the liquid. In the present embodiment, since the waste liquid tank 8 is arranged so as to be removable from the rear of the device, it can be easily replaced before absorbing the waste ink exceeding the holding capacity of the absorbing member 81, and the waste ink leaks and the like. It can be suppressed, and the decrease in the life of the recording device 1 can be suppressed.

As described above, according to the present embodiment, the inclined portion 60 forms a valley-shaped slope in the width direction of the flow path 600 by the side walls 61 and 62. Thereby, for example, the inclination angle of each slope can be increased as compared with the case of forming one slope inclined downward in the flow direction of the flow path 600. Therefore, the waste ink can easily go down the slope, and the waste ink can be moved more effectively. Further, since the valley-shaped slope is formed in the width direction of the flow path 600, the slope itself can be ensured even if the slope of the flow path 600 is gentle, so that the flow path forming portion 6 has a height. It is possible to suppress the increase in size in the direction, and it is possible to suppress the increase in size of the device.

Further, in the present embodiment, since the waste ink collects on the center side in the width direction of the flow path 600 due to the valley-shaped slope, the small ink droplets tend to coalesce into large ink droplets. The larger the ink droplets, the greater the influence of the gravity that tries to move the ink droplets down the slope than the influence of the surface tension that tries to keep the ink droplets in place. It can be moved effectively.

Further, according to the present embodiment, by moving the waste ink more effectively, the time for the waste ink to stay in the flow path forming portion 6 is reduced, so that the waste ink leaks and the recording medium 3 is contaminated. It is possible to suppress the occurrence of adhesion of ink. Specifically, when the recording device 1 is tilted for transportation or the like while the waste ink is accumulated on the slope of the flow path forming portion 6, it is retained in the flow path forming portion 6. It is possible to prevent the existing ink from leaking out from a gap or the like on the exterior of the device. Further, when the recording device 1 is tilted, it is possible to prevent the ink staying in the flow path forming portion 6 from adhering to the transport roller 22 or the like and contaminating the recording medium 3 with waste ink. Can be done.

In addition, if the waste ink stays on the slope for a long time, the water content of the ink droplets evaporates and the residual components of the evaporated ink solidify on the slope, and the next small ink droplets discharged also evaporate at the same place. By repeating the above steps, waste ink deposits on the slope gradually accumulated, and there was a possibility that the deposits adhered to the recording medium or the ink deposits leaked from the gaps on the exterior of the device. According to the present embodiment, the valley-shaped slopes formed by the side walls 61 and 62 make it easier for the waste ink to move, so that the time for the waste ink to stay in the flow path forming portion 6 is reduced. It is possible to suppress the generation of ink deposits, the leakage of the deposits to the outside of the device, and the adhesion of the deposits to the recording medium 3.

Further, according to the present embodiment, a bottom portion 71 is provided so as to connect both lower edges of the side walls 61 and 62, and the bottom portion 71 is formed in a groove shape. The groove-like shape makes it easier for ink droplets to collect. Therefore, small ink droplets tend to coalesce into large ink droplets, and the ink droplets are more likely to move on the bottom 71 due to the increased action of gravity.

Further, according to the present embodiment, the flow path forming portion 6 includes two inclined portions 60a and 60b, and the flow paths 600a and 600b thereof are arranged substantially in the center of the flow path forming portion 6. As a result, the flow path 600 can be shortened as compared with the case where the inclined portion 60 is one, and the height of the flow path forming portion 6 can be further suppressed while ensuring the inclined angle of each slope. Further, since the flow path 600 can be formed in a wider range in the width direction, the degree of freedom in arranging the absorbing member 5 can be ensured.

<Other embodiments>
In the above embodiment, the inkjet recording device 1 which is a printer having only a recording function as a liquid discharging device is exemplified, but as another example of the liquid discharging device, a multifunction printer having a copy function, a facsimile function, or the like can be mentioned. Be done. Further, the liquid ejection device is not limited to the one that ejects ink as a liquid, and may be one for ejecting a liquid to a substrate and performing an imprint process.

Further, it is also possible to adopt a configuration in which at least a part of the flow path forming portion 6 is subjected to a water-repellent treatment such as a fluorine coat. This makes it easier for waste ink to move by gravity even on gentle slopes compared to the case where water repellent treatment is not applied, and the height of slopes and grooves can be lowered, making it possible to further reduce the size of the device. Become.
