Description

  The present invention relates to an ink jet recording apparatus.

  Conventionally, an ink jet recording apparatus including a wiper blade is known. The wiper blade cleans the ink discharge surface of the recording head. The ink ejection surface is a surface provided with nozzles for ejecting ink in the recording head. The ink jet recording apparatus moves the wiper blade while pressing the wiper blade against the ink discharge surface, thereby wiping off ink adhering to the ink discharge surface (hereinafter sometimes referred to as “wiping”).

  The ink wiped off during wiping adheres to the tip of the wiper blade. Therefore, the image forming apparatus described in Patent Literature 1 includes a guide member (contact member) and a wiper cleaner (fiber member). The wiper blade which has finished wiping off the ink is sandwiched between the guide members via the wiper cleaner. As a result, ink adhering to the top surface of the wiper blade is absorbed.

JP 2001-71513 A

  However, in the image forming apparatus described in Patent Document 1, there is a possibility that ink adhering to the wiper blade is absorbed by the wiper cleaner and further passes through the wiper cleaner and adheres to the guide member. When the wiper blade comes into contact with the guide member via the wiper cleaner, the ink attached to the guide member may adhere to the wiper blade again. Therefore, the wiper blade may be contaminated, and the accuracy of ink wiping may be reduced.

  The present invention has been made in view of the above problems, and provides an ink jet recording apparatus that suppresses ink from adhering to an abutting member that abuts against a fiber member while cleaning ink adhering to a wiper blade. It is an object.

  An ink jet recording apparatus according to an aspect of the present invention includes a recording head, a wiper blade, and a cleaning mechanism. The recording head ejects ink onto the recording medium. The wiper blade cleans the ink ejection surface of the recording head. The cleaning mechanism cleans the wiper blade. The cleaning mechanism includes a fiber member and a contact member. The fiber member has a band shape, and includes a first surface against which the wiper blade is pressed and a second surface opposite to the first surface. The contact member is disposed to face the second surface of the fiber member, and contacts the fiber member when the wiper blade is pressed against the fiber member. The mass per unit area of the second surface of the fiber member is greater than the mass per unit area of the first surface of the fiber member.

  According to the present invention, while adhering to the wiper blade, the ink is prevented from adhering to the contact member that contacts the fiber member while cleaning the ink.

The wiper unit 60 uses the wiper blade 20 to wipe off the ink adhering to the head unit 3 (wiping). For example, when the wiper blade 20 performs wiping, the control unit 50 first lowers the first transport unit 205. Then, the control unit 50 horizontally moves the wiper unit 60 so as to be positioned at a standby position below the head unit 3 (a position between the head unit 3 and the first transport unit 205). Thereafter, the control unit 50 raises the wiper unit 60 to wipe the head unit 3. Details of the wiper unit 60 will be described later.

  The cap unit 290 is disposed below the second transport unit 212 and above the wiper unit 60. The cap unit 290 is attached to the head unit 3 when the head unit 3 is not used for a certain period of time. Thereby, drying of the ink in the head part 3 is prevented. For example, when the cap unit 290 is attached to the head unit 3, the control unit 50 lowers the first transport unit 205. Then, the control unit 50 horizontally moves the cap unit 290 to be positioned at a standby position below the head unit 3. Thereafter, the control unit 50 raises the cap unit 290 and attaches the cap unit 290 to the head unit 3. The cap unit 290 is detachably attached to the head unit 3. Details of the cap unit 290 will be described later.

  Next, the configuration of the head unit 3 and the recording head 10 will be described in detail with reference to FIGS. FIG. 2 is a perspective view of the head unit 3 according to the embodiment. The head unit 3 further includes a head housing 18. A plurality of types of line heads 10Y, 10M, 10C, and 10K are held by the head housing 18. The line head 10Y is a yellow line head. The line head 10M is a magenta line head. The line head 10C is a cyan line head. The line head 10K is a black color line head.

  The line heads 10Y, 10M, 10C, and 10K are arranged in the order of the line head 10K, the line head 10C, the line head 10M, and the line head 10Y from the upstream side to the downstream side in the transport direction D0 of the paper P. In the present embodiment, each of the line heads 10Y, 10M, 10C, and 10K includes three recording heads 10 that are arranged in a staggered manner along a direction orthogonal to the transport direction D0 (the X-axis direction in the present embodiment). Including. Each of the three recording heads 10 of the line head 10Y ejects yellow ink. Each of the three recording heads 10 of the line head 10M ejects magenta ink. Each of the three recording heads 10 of the line head 10C ejects cyan ink. Each of the three recording heads 10 of the line head 10K ejects black ink.

  FIG. 3 is a side view of the recording head 10. The recording head 10 includes a plurality of nozzles 11, an ink inlet 13, and an ink outlet 15. The surface on which the plurality of nozzles 11 are provided in the recording head 10 is an ink ejection surface 17. The plurality of nozzles 11 are arranged, for example, at the center of the ink ejection surface 17. The nozzle 11 ejects ink for forming an image on the paper P. Further, the nozzle 11 discharges ink together with unnecessary matter in the recording head 10 in the purge process.

  Next, the wiper unit 60 will be described with reference to FIG. FIG. 4 is a configuration diagram of the wiper unit 60. The wiper unit 60 further includes a moving mechanism 30. In FIG. 4, only one wiper blade 20 is shown for convenience of explanation, but actually, the wiper unit 60 includes a plurality of wiper blades 20 corresponding to the plurality of recording heads 10, respectively. One wiper blade 20 of the plurality of wiper blades 20 wipes the ink ejection surface 17 of the corresponding recording head 10. The wiper blade 20 has elasticity. The wiper blade 20 is made of, for example, an elastic member, specifically, synthetic rubber or synthetic resin.

  Ink discharged or discharged by the nozzles 11 during image formation or purge processing flows into the recording head 10 via an ink inlet 13 from an ink tank (not shown). Ink in the ink tank is prevented from evaporating its volatile components. Accordingly, the ink ejected or discharged from the nozzle 11 is a fresh ink (fresh ink) Nf that has not been thickened.

  The moving mechanism 30 moves the wiper blade 20 in accordance with an instruction from the control unit 50. In the present embodiment, the moving mechanism 30 can move the wiper blade 20 in the wiping direction D1, the ascending direction D3, and the descending direction D4 opposite to the ascending direction D3. The wiping direction D1 is a direction along the X axis, that is, a direction along the ink discharge surface 17. The ascending direction D3 and the descending direction D4 are directions along the Z axis.

  The wiping of the ink discharge surface 17 performed by the wiper unit 60 will be described. First, the control unit 50 causes the recording head 10 to perform a purge process, and causes the ink discharge surface 17 to discharge fresh ink Nf. Next, the control unit 50 controls the moving mechanism 30 to move the wiper blade 20 in the ascending direction D3 and press the wiper blade 20 against the ink ejection surface 17 so that the wiper blade 20 is bent. Then, the control unit 50 controls the moving mechanism 30 to move the wiper blade 20 in the wiping direction D1 while pressing the wiper blade 20 against the ink ejection surface 17. As a result, the wiper blade 20 can wipe the ink on the ink ejection surface 17.

  Wiping off the ink adhering to the ink ejection surface 17 means that the ink ejection surface 17 is cleaned. That is, the wiper blade 20 wipes the ink and fresh ink Nf on the ink ejection surface 17 and wipes unnecessary matter (for example, dust and dirt) adhering to the ink ejection surface 17 to clean the ink ejection surface 17.

  Next, the cap unit 290 will be described with reference to FIGS. 1, 2, 5, and 6. FIG. 5 is a perspective view showing the cap unit 290 from below. The cap unit 290 includes a cap portion 291 and a plurality of cleaning mechanisms 80. The cap part 291 includes an attachment surface 290 a that faces the wiper part 60.

  The plurality of cleaning mechanisms 80 are attached to the attachment surface 290 a of the cap portion 291 corresponding to each of the plurality of recording heads 10. That is, each of the plurality of cleaning mechanisms 80 is attached to the attachment surface 290a in a staggered manner along a direction orthogonal to the transport direction D0 (X-axis direction in the present embodiment). According to the present embodiment, the space for arranging the cleaning mechanism 80 and the cap unit 290 can be omitted as compared with the case where the cleaning mechanism 80 and the cap unit 290 are arranged separately. The cleaning mechanism 80 is screwed to the attachment surface 290a, for example.

  FIG. 6 is a side view showing the cleaning mechanism 80. The cleaning mechanism 80 cleans the wiper blade 20 that is disposed corresponding to each of the plurality of recording heads 10. The cleaning mechanism 80 includes a main body 81, a fiber member 83, a contact member 91, a support member 93, a feed roller 87, a take-up roller 85, a shaft 85 a, and a pair of guide rollers 89.

  The fiber member 83 has a strip shape. The fiber member 83 includes a first surface F1 against which the wiper blade 20 is pressed, and a second surface F2 facing the first surface F1. The mass per unit area of the second surface F2 of the fiber member 83 is larger than the mass per unit area of the first surface F1 of the fiber member 83.

  The fiber member 83 is a synthetic resin having thermoplasticity. The fiber member 83 is, for example, nylon or rayon. In the present embodiment, the fiber member 83 attached to the main body 81 is preheated. Specifically, among the fiber members 83 attached to the main body 81, the first surface F1 is heated at a low temperature, and the second surface F2 is heated at a high temperature. For example, the first surface F1 is heated at 30 ° C., and the second surface F2 is heated at 120 ° C. Accordingly, the first surface F1 heated at a low temperature is fluffed with fibers, and the second surface F2 heated at a high temperature is in close contact with the fibers. That is, the mass per unit area of the second surface F2 of the fiber member 83 is larger than the mass per unit area of the first surface F1 of the fiber member 83. As a result, the liquid absorbency of the second surface F2 of the fiber member 83 is suppressed while the liquid absorbency of the first surface F1 of the fiber member 83 is maintained.

  In the present embodiment, the high temperature is, for example, a temperature that is equal to or higher than the softening point of the fiber member 83 and lower than the melting point. On the other hand, the low temperature is, for example, a temperature lower than the softening point of the fiber member 83. Therefore, according to the material of the fiber member 83, the temperature which heats the 1st surface F1 of the fiber member 83, and the temperature which heats the 2nd surface F2 are each changed.

  Further, the fiber member 83 is previously compressed. For example, the fiber member 83 may be heated and compressed through a nip formed by a roller heated to a low temperature and a roller heated to a high temperature. In this case, the fiber member 83 passes through the nip so that the first surface F1 faces the roller heated to a low temperature and the second surface F2 faces the roller heated to a high temperature. As a result, while the fiber member 83 is compressed, the first surface F1 is heated at a low temperature and the second surface F2 is heated at a high temperature.

  One end of the fiber member 83 is wound around the feed roller 87. The other end of the fiber member 83 is wound around a winding roller 85. The shaft 85a supports the winding roller 85. In the present embodiment, a motor (not shown) is connected to the shaft 85a. Accordingly, when the driving force is transmitted from the motor to the shaft 85a, the winding roller 85 rotates. In the present embodiment, the winding roller 85 rotates counterclockwise. As a result, the take-up roller 85 takes up the fiber member 83, and the feed roller 87 sends out the fiber member 83 taken up by the take-up roller 85. The moving direction of the fiber member 83 is a direction in which the winding roller 85 winds the fiber member 83.

  The pair of guide rollers 89 is pressed against the second surface F <b> 2 of the fiber member 83 between the feed roller 87 and the take-up roller 85. Therefore, the guide roller 89 applies tension (tension) to the fiber member 83. The fiber member 83 is moved by the rotation of the feed roller 87 and the take-up roller 85, and the pair of guide rollers 89 are driven by the fiber member 83 to rotate.

  The contact member 91 and the support member 93 are disposed so as to face the second surface F <b> 2 of the fiber member 83. The contact member 91 and the support member 93 support the fiber member 83. The contact member 91 and the support member 93 have elasticity. That is, the contact member 91 and the support member 93 are formed of an elastic material such as sponge, rubber, or rubber sponge (foam rubber), for example. The contact member 91 is disposed so as to be located upstream of the support member 93 with respect to the moving direction of the fiber member 83.

  The contact member 91 and the support member 93 may be disposed in contact with the second surface F2 of the fiber member 83, or may be disposed at a predetermined interval from the second surface F2 of the fiber member 83. Good. When the contact member 91 and the support member 93 are arranged at a predetermined interval from the second surface F2 of the fiber member 83, when the wiper blade 20 is pressed against the fiber member 83, the contact member 91 and The support member 93 contacts the second surface F2 of the fiber member 83.

  Next, cleaning of the wiper blade 20 will be described with reference to FIG. FIG. 7A shows the wiper blade 20 pressed against the first region L <b> 1 of the fiber member 83. The first surface F1 of the fiber member 83 includes a first region L1 and a second region L2. In the present specification, a portion of the first surface F1 of the fiber member 83 between the contact member 91 and the support member 93 is defined as a first region L1, and a portion facing the contact member 91 is a second region. It is defined as L2. First, the wiper blade 20 to which ink is attached is pressed against the fiber member 83 a plurality of times so as to come into contact with the first region L1 of the fiber member 83. Therefore, the ink adhering to the wiper blade 20 is absorbed by the first region L1 of the fiber member 83.

  The first region L1 is supported by the contact member 91, the support member 93, and the wiper blade 20. Therefore, a predetermined tension is evenly applied to the first region L1 of the fiber member 83, and the extension of the fiber member 83 due to the contact of the wiper blade 20 is suppressed. As a result, the ink adhering to the wiper blade 20 is efficiently absorbed by the fiber member 83. In addition, since the tip of the wiper blade 20 contacts the fiber member 83 uniformly, the tip of the wiper blade 20 is uniformly cleaned.

  FIG. 7B shows the wiper blade 20 pressed against the second region L <b> 2 of the fiber member 83. After the wiper blade 20 is pressed against the first region L1 a plurality of times, the wiper blade 20 is pressed against the fiber member 83 a plurality of times so as to contact the second region L2 of the fiber member 83. Accordingly, the ink adhering to the wiper blade 20 is absorbed and cleaned by the second region L2 of the fiber member 83. As a result, in the second region L2, ink remaining in the wiper blade 20 that is not absorbed in the first region L1 is wiped off.

  If the force for pressing the wiper blade 20 against the contact member 91 via the fiber member 83 is too strong, the wiper blade 20 may buckle. Therefore, it is preferable that the force for pressing the wiper blade 20 against the fiber member 83 is a magnitude that does not cause the wiper blade 20 to buckle.

  After the wiper blade 20 is pressed against the second region L2 a plurality of times, the take-up roller 85 rotates and the fiber member 83 is taken up. The wiper blade 20 comes into contact with the second region L2 of the fiber member 83 after the ink is substantially removed by contacting the first region L1 of the fiber member 83. That is, a small amount of ink is absorbed in the second region L2 of the fiber member 83. Therefore, for example, the fiber member 83 is wound so that the portion of the fiber member 83 located in the second region L2 is located in the first region L1. Therefore, the first region L1 of the fiber member 83 that has absorbed a small amount of ink absorbs most of the ink adhering to the wiper blade 20, and the second region L2 of the fiber member 83 that has not absorbed ink absorbs the wiper blade 20. The ink remaining in the ink is absorbed. As a result, the usage amount of the fiber member 83 is reduced. As a result, the replacement frequency of the fiber member 83 by the user can be reduced.

  According to this embodiment, after the ink adhering to the wiper blade 20 is absorbed in the first region L1, the ink remaining on the wiper blade 20 is further absorbed in the second region L2. As a result, the efficiency of absorbing ink adhering to the wiper blade 20 is improved.

  Further, according to the present embodiment, the wiper blade 20 is repeatedly pressed against the fiber member 83 a plurality of times. As a result, the efficiency of absorbing ink adhering to the wiper blade 20 is further improved.

  Furthermore, according to the present embodiment, the mass per unit area of the second surface F2 of the fiber member 83 is larger than the mass per unit area of the first surface F1 of the fiber member 83. Therefore, the liquid absorption property of the first surface F1 of the fiber member 83 is high, and the liquid absorption property of the second surface F2 of the fiber member 83 is low. As a result, while the ink adhering to the wiper blade 20 is absorbed by the first surface F1 of the fiber member 83, the absorption to the second surface F2 of the fiber member 83 is suppressed, and the ink adhering to the wiper blade 20 is reduced The adhesion to the contact member 91 through 83 can be suppressed. As a result, the contamination of the wiper blade 20 due to the contamination of the contact member 91 is suppressed.

  Furthermore, according to the present embodiment, the contact member 91 is disposed to face the second region L2 of the fiber member 83. Therefore, the expansion of the fiber member 83 due to the wiper blade 20 being pressed against the fiber member 83 is suppressed. As a result, the fiber member 83 efficiently absorbs ink attached to the wiper blade 20.

  Furthermore, according to the present embodiment, the contact member 91 is disposed to face the second region L2 of the fiber member 83. Accordingly, the tip of the wiper blade 20 is pressed so as to bite into the fiber member 83. As a result, when the tip of the wiper blade 20 has irregularities, the fiber member 83 efficiently absorbs ink attached to the irregularities of the wiper blade 20.

  Furthermore, according to the present embodiment, the wiper blade 20 is pressed so as to bite into the second region L <b> 2 of the fiber member 83 where the contact member 91 is disposed to face the wiper blade 20. Accordingly, the ink adhering to the side surface of the wiper blade 20 is absorbed by the fiber member 83. As a result, when the wiper blade 20 wipes the ink discharge surface 17, it is possible to suppress the ink attached to the wiper blade 20 from attaching to the ink discharge surface 17.

  Furthermore, according to this embodiment, the fiber member 83 is compressed. As a result, the cleaning mechanism 80 can be reduced in size.

  As described above with reference to FIGS. 1 to 7, according to the present embodiment, the mass per unit volume of the second surface F <b> 2 of the fiber member 83 is the unit volume of the first surface F <b> 1 of the fiber member 83. Greater than hit weight. Accordingly, the liquid absorbency of the second surface F2 of the fiber member 83 is suppressed while maintaining the liquid absorbency of the first surface F1 of the fiber member 83. As a result, it is possible to suppress the ink from adhering to the contact member 91 via the second surface F2 of the fiber member 83 while cleaning the ink adhering to the wiper blade 20. As a result, contamination of the wiper blade 20 due to contamination of the contact member 91 is suppressed.
