Description

  The present invention relates to a liquid ejecting apparatus.

  2. Description of the Related Art Conventionally, ink jet recording apparatuses (hereinafter referred to as printers) are widely known as liquid ejecting apparatuses that eject liquid from a liquid ejecting head to a target. Such a printer has a so-called cleaning operation that sucks ink and bubbles with high viscosity in the nozzles by sucking ink from the nozzles of the recording head as a liquid jet head so that printing is performed satisfactorily. To be done.

  Incidentally, in recent years, it has been known that a printer uses inks of a plurality of colors such as cyan, magenta, yellow, and black in order to enable color printing. In such a printer, by performing the above-described cleaning operation, ink is sucked from nozzle rows that are not clogged, and unnecessary ink is consumed. In view of this, a cap has been proposed in which a plurality of box portions are formed by dividing the internal space of the cap by a wall portion, and each box portion receives each ink individually (for example, Patent Documents). 1).

  According to Patent Document 1, each box portion seals a different nozzle row among a plurality of nozzle rows. Each box portion is provided with an ink absorber, and the ink absorber receives the ink discharged from the corresponding nozzle row and feeds it to the suction pump side. As a result, ink is selectively absorbed, and waste of ink is prevented.

  Some printers eject reactive ink from a recording head in addition to normal color ink in order to improve the color developability and glossiness of a printed image. Specifically, the reactive ink is composed of clear ink or the like, and improves color developability and glossiness by aggregating reaction with the color ink on the recording medium.

In such a printer, by performing the above-described cleaning operation, there is a possibility that the color ink and the reactive ink cause an agglomeration reaction in the cap or the like, thereby reducing the function of the cleaning mechanism. Therefore, even in such a printer, by adopting a cap divided into a plurality of box portions as in Patent Document 1, it is possible to prevent agglomeration reaction and prevent the function of the cleaning device from deteriorating. It is like that.

  However, in the cap as described above, a regulating member that regulates the movement of the ink absorbing material disposed in the box part is provided for each box part. Also, the valve mechanism provided in the cap is provided for each box part. For this reason, the cap has a problem that the structure thereof is complicated and the number of parts is increased.

  An object of the present invention is to provide a liquid ejecting apparatus having a cleaning device that is simple in structure and has a small number of parts.

  The present invention includes a liquid ejecting head in which a plurality of nozzles are formed on a nozzle forming surface, and a liquid ejecting head that ejects liquid to a target through the nozzles, and an outer peripheral wall that forms an opening toward the nozzle forming surface, In the liquid ejecting apparatus including a cap capable of covering the nozzle by bringing a wall into contact with the nozzle forming surface, the cap divides a space in the cap into a plurality of divided chambers. When dividing walls are provided, an absorbent material that absorbs liquid ejected from the liquid ejecting head is provided in each of the divided chambers, and when the outer peripheral wall is in contact with the nozzle forming surface, A notch portion communicating with the dividing chamber was formed, and a regulating member for restricting the movement of the absorbent provided in each dividing chamber was provided across the notch portion.

  According to this, the space in the cap is divided into a plurality of divided chambers by the dividing wall. Each of the plurality of divided chambers is provided with an absorbing material that absorbs the liquid ejected from the liquid ejecting head. Furthermore, in order to regulate the movement of the absorbent material, a regulating member is provided across the notch formed in the dividing wall. For this reason, each division | segmentation chamber can share one control member mutually through a notch part. As a result, the cleaning device can have a simple structure, and the number of parts can be reduced.

In the liquid ejecting apparatus, the dividing wall is formed to be lower than a height position of the regulating member.
According to this, the upper end part of a division wall will always be located below rather than the height position of a control member. For this reason, a regulating member can be provided more easily across the dividing wall. Therefore, the cleaning device can have a simple structure, and the number of parts can be reduced.

  In the liquid ejecting apparatus, a suction unit that transfers the liquid inside the cap to the outside of the cap and an air communication unit that opens the division chamber to the atmosphere are provided in one of the division chambers.

  According to this, each division chamber can share one regulation member mutually through the notch part formed in the division wall. Further, one means for communicating with the atmosphere can be shared as means for communicating with the atmosphere. Therefore, the cleaning device can have a simple structure, and the number of parts can be reduced.

And a regulating member that regulates the movement of the absorbent material provided in each of the dividing chambers across the dividing wall.

Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1, a printer 10 as a liquid ejecting apparatus according to this embodiment includes a frame 11.

  A platen 24 is installed on the frame 11 in the main scanning direction (X-axis direction), and a printing paper P as a recording medium is placed on the platen 24 by a paper feed mechanism (not shown) in the sub-scanning direction (Y-axis direction). The paper is fed into the printer. A waste liquid tank 25 is provided below the platen 24. As shown in FIG. 3, the waste liquid tank 25 is formed in a box shape whose upper surface is open. Further, the waste liquid tank 25 is provided with a wall portion 26 at the center position, and the waste liquid tank 25 is formed with two divided chambers 25a and 25b. In the two divided rooms 25a and 25b, a plurality of waste liquid absorbers 27 made of a porous material are stacked.

  A guide member 13 is installed on the frame 11 in parallel with the platen 24. A carriage 15 is inserted into and supported by the guide member 13 so as to be movable. The carriage 15 is connected to the carriage motor 18 via the timing belt 16, and is reciprocated along the direction along the guide member 13, that is, along the main scanning direction X, by driving the carriage motor 18.

  A color ink cartridge 22 and a reactive ink cartridge 23 are mounted on the carriage 15 as shown in FIG. The color ink cartridge 22 contains ink as liquids of four colors (cyan, magenta, yellow, and black). The reactive ink cartridge 23 contains reactive ink as a liquid for achieving color development and glossiness of the printed image. Both cartridges 22 and 23 are detachably attached to the carriage 15.

  A recording head 20 is mounted below the carriage 15, and a nozzle forming surface 20a is formed on the lower surface of the recording head 20 as shown in FIG. The nozzle forming surface 20a has four nozzle rows 21a to 21d corresponding to the four color inks of the color ink cartridge 22 in the left half portion in FIG. 2, and the right half portion in FIG. One nozzle row 21e corresponding to the reactive ink of the reactive ink cartridge 23 is formed in the portion.

  Then, when a piezoelectric element (not shown) is driven in the recording head 20, each ink supplied from each cartridge 22, 23 becomes an ink droplet on the printing paper P from each nozzle row 21 a to 21 e of the recording head 20. It comes to discharge.

Then, when the piezoelectric element is driven based on the print data while reciprocating along the guide member 13 with the carriage 15 facing the print paper P, the recording head 20 applies the print paper P to the print paper P. Ink is ejected and printing is performed. In the present embodiment, after the ink droplets of the color ink are ejected, the reactive ink is ejected onto the ink droplets of the color ink attached to the printing paper P. The reactive ink adheres to the color ink, so that it reacts with the color ink on the printing paper P to enhance the color developability and glossiness of the color ink. As a result, an image with improved coloring and gloss is printed on the printing paper P.

As shown in FIG. 1, a cleaning device 30 is provided in a non-printing area (home position) at the right end of the printer 10. The cleaning device 30 cleans the recording head 20 in order to prevent printing defects. As shown in FIG. 3, the cleaning device 30 includes a cap 32, suction tubes 37 and 38 constituting suction means connected to the cap 32, and suction means provided in the middle of the suction tubes 37 and 38. And a suction pump 39.

  FIG. 4 is an overall perspective view of the cap 32 of the cleaning device 30. The cap 32 is provided so as to be reciprocally movable in a vertical direction (Z-axis direction) by a known lifting means (not shown). The surface 20a is sealed. As shown in FIGS. 5 and 6, the cap 32 includes a substantially rectangular bottom surface 33, and an outer peripheral wall 41 formed in a square frame shape standing along the outer periphery of the bottom surface 33. It is formed in a substantially box shape whose side is open. In the present embodiment, it is assumed that the size of the bottom surface 33 is slightly smaller than the nozzle forming surface 20a (see FIG. 2) of the recording head 20.

  Further, the cap 32 includes a dividing wall 42 erected so as to be along the sub-scanning direction at the center of the bottom surface 33. The partition wall 42 divides the space formed by the bottom surface 33 of the cap 32 and the outer peripheral wall 41 into two to form a first partition chamber 44 and a second partition chamber 45. That is, the cap 32 is formed by the bottom surface 33, the outer peripheral wall 41, and the dividing wall 42 so that the first dividing chamber 44 and the second dividing chamber 45 have substantially the same volume. In the present embodiment, the dividing wall 42 has a notch 43 formed at the upper end thereof. The notch 43 is formed by notching the upper end of the dividing wall 42 to the full width in the vertical direction and the vicinity of both ends 42a in the sub-scanning direction (see FIG. 5).

  In addition, the dividing wall 42 is formed such that the height of both end portions 42 a excluding the notch portion 43 is the same as the height of the outer peripheral wall 41. Therefore, when the outer peripheral wall 41 seals the nozzle forming surface 20 a of the recording head 20, the first and second divided chambers 44 and 45 are communicated with each other by the notch 43.

  As shown in FIG. 4, first and second ink absorbing materials 47 and 48 are accommodated in the first and second divided chambers 44 and 45, respectively. The first and second ink absorbing materials 47 and 48 are both the same material and have the same thickness, and the upper surface thereof is substantially at the same height as the upper end portion of the cutout portion 43 of the dividing wall 42. .

  As shown in FIGS. 5 and 6, seven substantially cylindrical support members 46 project from the bottom surfaces 33 of the first and second divided chambers 44 and 45, respectively. When the first and second ink absorbing materials 47 and 48 are accommodated in the first and second divided chambers 44 and 45, respectively, the penetrations formed in the first and second ink absorbing materials 47 and 48 are provided. When the support 46 passes through the hole, the first and second ink absorbing materials 47 and 48 are positioned inside the first and second divided chambers 44 and 45, respectively.

As shown in FIG. 4, the upper surfaces of the first and second ink absorbing materials 47 and 48 supported and fixed to the support 46 are used to restrict the swelling of the first and second ink absorbing materials 47 and 48. The regulating member 49 is laid in the first and second dividing chambers 44 and 45 across the notch 43 of the dividing wall 42.

  The restricting member 49 is made of metal, and is provided in a rectangular frame portion 49a disposed on the top surfaces of the first and second ink absorbing materials 47 and 48, and in each corner and in the middle of the frame portion 49a. And a circular portion 49b. Further, the regulating member 49 includes an intersecting portion 49c that intersects in a substantially cross shape within the frame portion 49a, thereby improving the strength of the regulating member 49. The restricting member 49 includes a bridge portion 49d as a portion connecting the frame portions 49a arranged on the upper surfaces of the first and second ink absorbing materials 47 and 48 across the cutout portion 43 of the dividing wall 42. The restricting member 49 is connected to and fixed to the upper ends of the supporting bodies 46 whose circular portions 49b protrude from the upper surfaces of the first and second ink absorbing materials 47 and 48, whereby the first and second circular members 49b are connected. The swelling of the ink absorbing materials 47 and 48 is regulated.

  In addition, as shown in FIG. 7, the cap 32 according to the present embodiment serves as a close contact portion formed of an elastic material such as an elastomer with respect to a resin portion 51 as a core portion formed of a resin such as plastic. The elastic material portion 52 is integrally formed by two-color molding or the like. The elastic material portion 52 is an upper end portion of the outer peripheral wall 41 and an upper end portion of both end portions 42a of the dividing wall 42, and is in close contact with the nozzle forming surface 20a of the recording head 20, thereby improving the airtightness of the space in the cap 32. It comes to secure.

  When the cap 32 and the nozzle forming surface 20a come into contact with each other, in this embodiment, the nozzle rows 21a to 21d of the nozzle forming surface 20a are covered with the first division chamber 44, and the nozzle row 21e is in the second division. The chamber 45 is covered. Accordingly, the color inks ejected from the nozzle rows 21a to 21d are received by the first ink absorbing material 47 of the first division chamber 44, and the reactive ink ejected from the nozzle row 21e is the second division chamber. It is received by 45 second ink absorbing material 48.

  As shown in FIGS. 6 and 7, a first discharge port 34 and a second discharge port 35 are formed through the bottom surfaces 33 of the first and second divided chambers 44 and 45, respectively. One end of the suction tube 37 is connected to the first discharge port 34. The second discharge port 35 is connected to one end of the suction tube 38. The suction tubes 37 and 38 are both made of a flexible material such as silicon rubber. As shown in FIG. 3, the other ends of the suction tubes 37 and 38 are respectively disposed in two divided chambers 25 a and 25 b formed in the internal space of the waste liquid tank 25. Accordingly, the inside of the first and second divided chambers 44 and 45 of the cap 32 and the waste liquid tank 25 are individually connected via the suction tubes 37 and 38, respectively.

  A suction pump 39 is provided in the middle of the flow path of the suction tubes 37 and 38, and when driven by a driving means (not shown), the upstream side of the suction tubes 37 and 38 can be decompressed. Yes. Therefore, when the suction pump 39 is driven in a state where the nozzle forming surface 20a of the recording head 20 is sealed by the cap 32, the space formed by the recording head 20 and the cap 32 is decompressed.

Further, as shown in FIGS. 6 and 7, an atmosphere communication port 36 is formed through the bottom surface 33 of the first division chamber 44 of the cap 32, and an atmosphere communication means 60 is configured in the atmosphere communication port 36. An atmospheric communication tube 40 is connected. The atmosphere communication tube 40 is formed of a flexible material such as silicon rubber, and the atmosphere communication tube 40 is provided with an atmosphere communication valve 55 that constitutes the atmosphere communication means 60. Therefore, when the atmospheric communication valve 55 is opened with the cap 32 sealing the nozzle forming surface 20a of the recording head 20, the first divided chamber 44 is at atmospheric pressure. At this time, since the second division chamber 45 communicates with the cutout portion 43 of the division wall 42, the second division chamber 45 also becomes atmospheric pressure.

Next, an operation during the cleaning operation of the printer 10 configured as described above will be described.
As shown in FIGS. 1 and 3, during the cleaning operation, first, the carriage 15 is moved to the hoe position, and the cap 32 is raised by the elevating means. As a result, the nozzle forming surface 20a of the recording head 20 of the carriage 15 and the cap 32 come into contact with each other.

  As described above, the nozzle rows 21 a to 21 d of the nozzle forming surface 20 a are covered by the first division chamber 44 of the cap 32, and the nozzle row 21 e is covered by the second division chamber 45 of the cap 32. .

  At this time, as shown in FIG. 7, the outer peripheral wall 41 of the cap 32 and both end portions 42a of the dividing wall abut against the nozzle forming surface 20a. Specifically, in the present embodiment, since the notched portion 43 is formed in the dividing wall 42, only the portion of both end portions 42 a excluding the notched portion 43 forms the nozzle together with the outer peripheral wall 41. It will contact | abut with respect to the surface 20a.

  When the suction pump 39 is driven in this state, the space formed by the recording head 20 and the outer peripheral wall 41 is decompressed. As a result, the color ink and the reactive ink are sucked from the nozzle rows 21a to 21e on the nozzle forming surface 20a of the recording head 20, respectively.

  At this time, the first divided chamber 44 and the second divided chamber 45 communicate with each other through the cutout portion 43 of the dividing wall 42, so that the inside of the first divided chamber 44 and the second divided chamber 45. The magnitude of the reduced pressure is equal. Accordingly, substantially the same amount of ink is sucked from each of the nozzle rows 21a to 21e on the nozzle forming surface 20a of the recording head 20.

  The first and second ink absorbers 47 and 48 accommodated in the first and second divided chambers 44 and 45 absorb the ink discharged from the nozzle forming surface 20a. The upward movement, that is, swelling is restricted.

  Then, among the sucked inks, the colored ink is discharged to the divided chamber 25 a formed in the waste liquid tank 25 through the first divided chamber 44 and the suction tube 37. In addition, among the sucked inks, the reactive ink is discharged to the divided chamber 25 b formed in the waste liquid tank 25 through the second divided chamber 45 and the suction tube 38.

  With the above cleaning operation, the agglomeration reaction between the colored ink and the reactive ink can be prevented in the cap 32 and the like, and the function of the cleaning device 30 can be prevented from being deteriorated. Also, in the waste liquid tank 25, the color ink and the reactive ink are separately discharged into the two divided chambers 25a and 25b, so that the aggregation reaction does not occur in the waste liquid tank 25, and the waste liquid is absorbed. It is possible to prevent the absorption efficiency of the material 27 from being lowered.

  In addition, the air communication valve 55 that was in the closed state during the cleaning operation is opened by a driving device (not shown) after the cleaning operation is completed. At this time, the first divided chamber 44 and the second divided chamber 45 that have been decompressed communicate with each other through a notch 43 formed in the dividing wall 42, so that the interior of the first divided chamber 44 is exposed to the atmosphere. Simultaneously with the communication, the second divided chamber 45 is also at atmospheric pressure. Thereafter, the cap 32 is separated from the recording head 20. As described above, the ink droplet ejection capability of the recording head 20 is recovered.

According to the above embodiment, the following effects can be obtained.
(1) In the above embodiment, the first and second ink absorbing materials 47 and 48 respectively accommodated in the first and second divided chambers 44 and 45 formed by the dividing wall 42 are used as one regulating member 49. Fixed. Therefore, the number of components of the cleaning device 30 can be reduced.

In addition, the restriction member 49 can fix the first and second ink absorbing materials 47 and 48 with a simple configuration in which the notch 43 is formed in the dividing wall 42.
(2) In the above-described embodiment, the first and second divided chambers 44 and 45 communicate with each other with a simple configuration in which the notch 43 is formed in the dividing wall 42.

  Thereby, it is not necessary to provide the atmospheric communication means for each of the first and second divided chambers 44 and 45, and only the atmospheric communication means 60 is provided in the first divided chamber 44. 44 and 45 can be communicated with the atmosphere. Therefore, since the number of valve mechanisms can be reduced, the number of components of the cleaning device 30 can be reduced.

  (3) In the above embodiment, in the cap 32, the color ink and the reactive ink are respectively applied to the first ink absorbing material 47 of the first dividing chamber 44 and the second ink absorbing material 48 of the second dividing chamber 45. Are discharged individually. As a result, the color ink and the reactive ink are mixed in the cap 32 to cause an agglomeration reaction, thereby suppressing a decrease in the absorption capacity of the first and second ink absorbing materials 47 and 48. it can.

  (4) In the above embodiment, the ink discharged into the first and second divided chambers 44 and 45 is individually supplied to the divided chambers 25a and 25b formed in the waste liquid tank 25 through the suction tubes 37 and 38, respectively. Is discharged. Thereby, in the waste liquid tank 25, it can suppress that the fall of the absorption capability of the waste-liquid absorber 27, etc. arise by mixing color ink and the reactive ink and causing aggregation reaction.

  (5) In the above embodiment, the notch 43 is formed in the dividing wall 42 so that the first and second dividing chambers 44 and 45 communicate with each other. Thereby, the magnitude | size of the pressure reduction inside the 1st and 2nd division | segmentation chambers 44 and 45 can be equalized at the time of cleaning operation | movement. Accordingly, substantially the same amount of ink is sucked from each of the nozzle rows 21 a to 21 e on the nozzle forming surface 20 a of the recording head 20. As a result, it is possible to prevent an extreme gap between the remaining amounts of ink in the cartridges 22 and 23.

  Further, since the notch 43 is formed at the upper end of the dividing wall 42, when the cap 32 is in contact with the nozzle forming surface 20a, the area where the dividing wall 42 and the nozzle forming surface 20a are in contact is inevitable. Becomes smaller. Accordingly, the ratio of the outer peripheral wall 41 to the area of the portion where the cap 32 and the nozzle forming surface 20a come into contact increases, and the outer peripheral wall 41 can come into contact with the nozzle forming surface 20a with a correspondingly large stress. . Thereby, the sealing performance of the outer peripheral wall 41 and the nozzle formation surface 20a can be improved, and the pressure inside the cap 32 can be reduced sufficiently. Accordingly, the drive energy of the cap 32 can be suppressed, and an increase in cost can be suppressed.

  (6) In the above embodiment, the outer peripheral wall 41 and the dividing wall 42 are configured by the resin portion 51 and the elastic material portion 52. And when the cap 32 contact | abutted with respect to the nozzle formation surface 20a, the elastic material part 52 was made to contact | abut with respect to the nozzle formation surface 20a. Thereby, the sealing performance between the cap 32 and the nozzle formation surface 20a can be improved. Accordingly, the drive energy of the cap 32 can be suppressed, and an increase in cost can be suppressed.

In addition, you may change the said embodiment as follows.
In the above embodiment, the first and second dividing chambers 44 and 45 span the notch portion 43 formed in the dividing wall 42, and the regulating member 49 is attached to the first and second ink absorbing materials 47 and 45. 48 was laid on the upper surface. Instead of this, the dividing wall 42 may be provided with a communication port through which the bridge portion 49d, which is a constituent part of the regulating member 49, can be inserted. As a result, the first and second ink absorbing materials 47 and 48 are restricted by the restricting member 49 from moving upward due to swelling or the like. Therefore, the number of components of the cleaning device 30 can be reduced.

  In the above embodiment, the notch 43 is formed in the dividing wall 42 so that the first and second dividing chambers 44 and 45 communicate with the atmosphere. Instead of this, the dividing wall 42 itself may be formed so as to be lower than the upper end portion of the outer peripheral wall 41. Accordingly, the first and second divided chambers 44 and 45 can be more easily communicated with the atmosphere without particularly forming the notch 43. Therefore, the cleaning device can have a simple structure, and the number of parts can be reduced.

In the above embodiment, the atmosphere communication means 60 is provided in the first division chamber 44. Instead, the atmospheric communication means 60 may be provided on the second division chamber 45 side.
In the above embodiment, the cap 32 is embodied so as to have only one dividing wall 42 and the inner space is divided into two. This may be embodied in such a manner that two or more dividing walls 42 are provided and the internal space is divided into three or more rooms, that is, three or more dividing chambers are formed. In such a case, it is only necessary to form the dividing walls 42 such that the dividing chambers communicate with each other, and to provide one atmospheric communication means 60 in any of the dividing chambers. Thereby, if the atmosphere communication valve 55 which comprises the atmosphere communication means 60 is made into an open state, all the three or more division chambers formed in the cap 32 can communicate with the atmosphere.

  In the above embodiment, the first and second divided chambers 44 and 45 of the cap 32 correspond to the combination of the color ink and the reactive ink, respectively. It is good also as a thing corresponding to. For example, the first division chamber 44 may correspond to pigment-based ink, and the second division chamber 45 may correspond to dye-based ink. Further, for example, the ink that hardly pseudo-aggregates with the reactive ink may correspond to the second divided chamber 45 together with the reactive ink.

  In the above-described embodiment, the printer 10 (printing apparatus including a facsimile, a copier, etc.) that ejects ink has been described as the liquid ejecting apparatus. However, a liquid ejecting apparatus that ejects another liquid may be used. For example, liquid ejecting devices for ejecting liquids such as electrode materials and color materials used for tax layers of liquid crystal displays, EL displays and surface-emitting displays, liquid ejecting devices for ejecting bioorganic substances used for biochip manufacturing, precision pipettes The material injection device may be used.
