Description

[0001]
BACKGROUND OF THE INVENTION
According to the present invention, an ink jet recording head that prints on a recording medium by ejecting ink droplets from a nozzle opening based on printing data, and a nozzle forming surface of the recording head on which the nozzle opening is formed are in sliding contact. The present invention relates to an ink jet recording apparatus including a wiping unit that performs cleaning.
[0002]
[Prior art]
For example, a serial printing type ink jet recording apparatus transports a recording paper as a recording medium in an ink jet recording head that is mounted on a carriage and reciprocates in a main scanning direction, and a sub scanning direction orthogonal to the main scanning direction. Paper feeding means is provided, and printing is performed on the recording paper by ejecting ink droplets from the recording head based on the print data.
[0003]
The recording head described above performs printing by ejecting ink pressurized in the pressure generating chamber as ink droplets from the nozzle opening onto the recording paper, and therefore, the ink viscosity increases due to evaporation of the ink solvent from the nozzle opening. In addition, there is a problem that printing failure occurs due to solidification of ink, adhesion of dust, and mixing of bubbles.
[0004]
For this purpose, the ink jet recording apparatus includes a capping unit for sealing the nozzle opening of the recording head during non-printing and a wiping member for cleaning the nozzle forming surface. The capping unit described above not only functions as a lid for preventing the ink in the nozzle opening from drying when printing is suspended, but also seals the nozzle forming surface with the capping unit when the nozzle opening is clogged. In addition, the negative pressure from the suction pump causes the ink to be sucked and discharged from the nozzle opening to eliminate clogging due to solidification of the ink at the nozzle opening and ejection failure of ink droplets due to air bubbles entering the ink flow path. I have.
[0005]
The forcible suction and discharge process of ink that is performed to eliminate clogging of the recording head and the mixing state of bubbles in the ink flow path is called a cleaning operation, and printing is performed after a long pause of the device. This process is executed when resuming or when the user recognizes that the quality of the recorded image has deteriorated and operates the cleaning switch or the like. Then, after the ink is discharged from the recording head by the negative pressure by the above-described capping means, the nozzle formation surface is wiped (wiped) by a wiping member formed of, for example, a rubber material or the like, thereby forming the nozzle. An operation of scraping off ink adhering to the surface is accompanied.
[0006]
In this case, at the start of the cleaning operation described above, it is necessary to remove the accumulation of ink adhering to the nozzle forming surface of the recording head in a thickened or solidified state. It is difficult to effectively remove the deposited deposit. In view of this, for example, a means has been proposed that includes a wiping member made of a felt material or the like and thereby removes the accumulated matter of ink adhering to the nozzle formation surface. The above-described wiping member made of a rubber material or the like is called a blade material, and the wiping member made of a felt material or the like is called a rubbing material.
[0007]
[Problems to be solved by the invention]
By the way, in the wiping means provided with the aforementioned blade material and rubbing material, both are formed in a flat plate shape (strip shape), and this is configured to be attached to the wiper holding member. However, since the above-mentioned blade material and rubbing material are small in size and difficult to handle and assemble, both are previously bonded with an adhesive, and the bonded wiping member is used as a wiper holding member. A built-in assembly procedure is adopted.
[0008]
However, the man-hours for bonding both of the above with an adhesive and the countermeasures against the volatilization of the solvent in this bonding process, and further problems such as adhesion of the adhesive to an unexpected part occur, and countermeasures are also necessary. It becomes. In addition, the sliding contact pressure (reaction force) of the bonded wiping member fluctuates due to the selection of the adhesive or the variation of the thickness of the adhesive layer, and it is difficult to ensure a predetermined design value range. It will also have problems such as becoming.
[0009]
  The present invention has been made by paying attention to the above-mentioned problems, and it is possible to attach both the blade material and the rubbing material together with no bonding means.SuperpositionThe present invention is intended to provide an assembly configuration in which these can be easily attached to the wiper holding member without causing a positional shift between them, thereby eliminating the conventional problems as described above. It is an object of the present invention to provide an ink jet recording apparatus that can be used.
[0010]

Further, the one wiping member is preferably formed with a plurality of convex portions constituting the positioning means, and the tip portions of the respective convex portions are formed so as to face each other, and the other wiping member is formed. In this configuration, a plurality of through-holes that are fitted into the respective convex portions and constitute positioning means are formed.
[0013]
  On the other hand, in a preferred embodiment, the wiper holding member is formed in a U shape,Overlapping stateAt least one of the first and second wiping members is housed and held in the central groove.
[0014]
In this case, the wiper locking means formed on the wiper holding member is preferably constituted by a protrusion protruding into the central groove, and is engaged with at least one of the first and second wiping members by the protrusion. The recessed part or through-hole to be stopped is formed. Furthermore, in this case, it is desirable that an inclined surface whose height gradually increases along the insertion direction of the wiping member is formed at the tip of the protrusion.
[0015]
In addition, the wiper locking means formed on the wiper holding member may be constituted by a concave portion or a through hole formed on one side surface of the folded wiper holding member formed in a U-shape. A convex portion formed on at least one of the first and second wiping members is configured to fit into the concave portion or the through hole of the wiper holding member.
[0017]
Further, the blade material constituting the first wiping member is disposed on the capping means side capable of sealing the nozzle forming surface of the recording head, and the rubbing material constituting the second wiping member is disposed on the printing region side. It is desirable that they are arranged.
[0018]
  According to the recording apparatus including the wiping means having the above-described configuration, the bonding means is formed by using the positioning means formed on the first and second wiping members, for example, by a combination of a convex portion and a concave portion (or a through hole). Without using the, without causing a shift in the positional relationship between the two,Overlapping stateCan be.
[0019]
  AndOverlapping stateBy accommodating at least one of the first and second wiping members made in the above in the central groove portion in the U-shaped wiper holding member,Overlapped stateThe wiping means having a configuration in which the first and second wiping members are held by the wiper holding member can be obtained. In this case, by applying wiper locking means to the wiper holding member,Overlapped stateThe first and second wiping members can be easily assembled to the wiper holding member using the wiper locking means.
[0020]
Therefore, according to the above-described configuration, the wiping means can be easily assembled, and the adhesive can be eliminated in the assembling process. Moreover, the variation in the sliding contact pressure caused by the wiping member caused by using the adhesive can be effectively suppressed.
