Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an inkjet recording apparatus that performs recording by ejecting ink from an ejection port of a printhead, and in particular, relates to an inkjet printing apparatus that performs printing by ejecting ink from an ejection port of a printhead. The present invention relates to an inkjet recording apparatus including a moving means for moving a cleaning member for removing foreign matter.

[Prior Art] In a conventional inkjet recording apparatus, a recording head for ejecting ink from an ejection port is formed with an ejection port surface on which a plurality of ejection ports are arranged in a row. The ejection port surface is contaminated with foreign matter such as ink and dust that bounced off the recording medium during recording, so as a means to remove them, the ink is rubbed relative to the ejection port surface. A cleaning member made of an elastic body is provided to remove dirt and foreign matter. Further, a moving means is provided for reciprocating the cleaning member between two stop positions when the cleaning member removes the ink and foreign matter.

Here, an example of the conventional cleaning member and moving means will be explained.

FIG. 6(a) is a front view of the moving means provided in a conventional inkjet recording apparatus, and FIG. 6(b) is a right side view thereof.

A carriage 52 on which the recording head 51 is mounted is slidably fitted to a guide shaft 53.
It is reciprocated by a driving means (not shown) along a recording medium (not shown) (located on the left side of the figure in FIG. 6(b)) that is conveyed so as to face the ejection port surface 51a of No. 1.

The recording head 51 is configured to perform recording on the recording medium by ejecting ink from its ejection openings while being moved along the recording medium.

Of the movement path of the recording head 51, the recording head 51
The cleaning member 54 and the moving means 55 are disposed at appropriate positions outside the recording area where recording is performed on the recording medium.

To explain the moving means 55, the holder 56 that holds the cleaning member 54 has its first cylindrical portion 56a.
The second cylindrical portion 56b is slidably fitted into a guide hole 57a bored in the base box 57, and is movable back and forth in a direction perpendicular to the moving direction of the recording head. It is always urged in the direction of arrow A due to tensile force. One end of a five-shaped lever 58 rotatably supported on a shaft 57d provided in a base box 57 is connected to the second cylindrical portion 56b of the halter 56, and the other end of the five-shaped lever 58 is connected to an output shaft 59a of a solenoid 59 attached to the base box 57.

The moving means 55 moves the cleaning member 54 to one of two stopping positions (the tip of the cleaning member 54 or a position protruding onto the movement path of the ejection port surface 51a of the recording head 51). Move it to that point and stop.

The action at the second time is similar to the one at the end. When the solenoid 59 is energized, its output l1illI59a contracts in the direction of arrow B, and this movement is transmitted to the halter 56 via the L-shaped groove 58, and the halter 56 moves in the opposite direction to the direction of arrow A. be done. The halter 56 has its first cylindrical portion 5

By rubbing the tip end of the recording head 51 against the ejection port surface 51a of the recording head 51 that has moved on the movement path, ink and foreign matter adhering to the ejection port surface 51a are removed.

When the removal of ink or foreign matter is not performed, the moving means 55 moves the cleaning member 54 to the retracted position, which is the other of the two stop positions (the tip of the cleaning member 54 is located above the recording head 51). Discharge port surface 5
(a position away from the movement path of 1a), then move and stop. The operation at this time is as follows. When the solenoid 59 is de-energized, the holter 56 is moved in the six directions of arrows by the tensile force of the spring 60. The halter 56 is stopped when the circumferential surface of the second cylindrical portion 56b comes into contact with the second fixing surface 57c of the guide hole 57a, and the cleaning member 54 is stopped at the retracted position.

The following conventional examples other than the cleaning member 54 and moving means 55 described above are also available.

The recording head stops at a predetermined position on its movement path outside the range of the recording area, and the moving means moves the cleaning member to a first stop position (an appropriate position on one end side of the ejection port surface of the stopped recording head). ) to a second stop position (an appropriate position on the other end side of the discharge port surface) and stop, and then
The cleaning member is moved from the second stop position to the first stop position and then stopped, and the tip of the cleaning member rubs against the discharge port surface during the reciprocating movement.
Ink and foreign matter adhering to the ejection port surface are removed.

The moving means is also configured to restlessly stop the cleaning link member at the first stop position and the second stop position by coming into contact with either a moving part or a stationary part of the moving means.

In the conventional example shown in FIGS. 6(a) and 6(b), the circumferential surface of the first cylindrical portion 56a of the bolter 56 (the moving part) and the first fixed surface 57b of the guide hole 57a (the stationary part) are in contact with each other. When in contact with the second cylindrical portion 5
When the peripheral surface of the kite 6b (moving part) and the second fixed surface 57C of the kite hole 57a (non-moving part) come into contact with each other, a contact sound is generated.

If both the moving and stationary parts are rigid bodies, there is a problem in that a large contact noise is generated, which goes against the recent demands for noise reduction in office equipment.

In addition, as a measure to reduce contact noise, is there a way to reduce contact noise by arranging a cushioning material such as rubber as a separate part at the contact part of the moving or non-moving parts? Providing the above-mentioned cushioning material in a small-sized transportation means has the problem that it takes time and effort to manufacture and increases the manufacturing cost.

The configuration is such that ink is ejected from the ejection ports to perform recording on the recording medium.

If the ejection ports of the recording head 1 become clogged with foreign matter such as thickened ink or dust, or if air bubbles enter the ink inside the recording head 1, ink ejection failure may occur. There is. As a means to recover from this ink ejection failure, the head recovery device 11 or an appropriate position (hereinafter referred to as " (referred to as "recovery position") is arranged corresponding to P (see Fig. 2).

The holder 6 has a structure in which the first cylindrical part 6a and the second cylindrical part 6b are slidably fitted into the guide hole 7b, so that the holder 6 can reciprocate in the direction of the arrow and in the opposite direction. It is constantly biased in the direction of the arrow by the tensile force of a spring 10 whose both ends are applied to the protruding bottle and a pin protruding from the side wall 7a. Further, a snap ring 6C is fitted into a portion of the first cylindrical portion 6a of the holter 6 that protrudes inside the base box 7 to prevent the holter 6 from coming off from the kite hole 7b.

A connecting pin 6d is protruded from the end surface of the second cylindrical portion 6b of the holder 6 that protrudes inside the base box 7.
The connecting pin 6d is loosely fitted into a hole 8a at one end of an L-shaped bar 8 rotatably supported by a shaft 7c provided on the side wall 7a. The output shaft 9 of a solenoid 9 attached to the base box 7 is inserted into the hole 8b at the other end of the L-shaped lever 8.
A connecting pin 9b press-fitted into a is loosely fitted.

At this point, the cleaning member 4 will be explained.

A plate-shaped cleaning member 4 made of an elastic material such as silicone rubber, urethane rubber, or HNBR rubber is attached to the holder 6.
Furthermore, the two fixing protrusions 6e and 6f protruding from the inner surface of the holder 6 are fitted into the two holes 4a and 4b bored in the cleaning member 4. , the cleaning member 4 is positioned and fixed (see FIGS. 1 and 3).

A rectangular first protrusion 4C is integrally formed on the surface of the cleaning member 4 on the base box 7 side, and the first protrusion 4C moves in the same direction as the moving direction of the recording head 1. It protrudes into the base box 7 through a hole bored in the holter 6 and a guide hole 7b in the side wall 7a. A first stopper surface 4d facing in the opposite direction to the arrow direction of the first protrusion 4C serves as a first stopper portion.

A portion of the inner wall of the guide hole 7b that faces the first stopper 4d serves as a first fixing surface 7d, and a portion of the side wall 7a that forms the first fixing surface 7d serves as the first fixing member.

On the other hand, two second protrusions 4e and 4f are provided at both ends of the surface of the cleaning member 4 facing in the direction of the arrow (see FIG. 1).
are formed integrally with each other, and each of the second protrusions 4
E and 4f respectively pass through two holes formed in the holter 6 in the direction of the arrow and protrude to the outside from the holter 6 by an appropriate length. each of the second protrusions 4e;
The second stopper, which is the end face facing in the direction of the arrow of 4f, is 4g.
, 4h respectively serve as second stopper portions.

On both sides of the kite hole 7b of the side wall 7a, there are two second fixing members 7e, 7f integrally formed in a rib shape, each having second fixing surfaces 7g, 7h facing the respective second stopper surfaces 4g, 4h. It is fidgety.

Next, the moving means 5 moves the cleaning member 4 between a cleaning position (a position where the leading end of the cleaning member 4 protrudes onto the moving path of the ejection port surface 1a of the recording head 1) and a retracted position. The operation of reciprocating the recording head 1 to and from a position remote from the movement path of the ejection opening surface 1a of the recording head 1 will be described (see FIG. 1).

When moving the cleaning member 4 to the cleaning position, the solenoid 9 is energized and output @9a or arrow E
This movement is transmitted to the halter 6 via the L-shaped bar 8, and the halter 6 is moved in the opposite direction to the arrow direction. The cleaning member 4 held by the holter 6 comes into contact with the first stopper surface 4d of the cleaning member 4 or the first fixing surface 7d of the guide hole 7b.
It is configured to stop at the cleaning position.

The distal end of the cleaning member 4 that has stopped at the cleaning position rubs against the ejection port surface 1a of the recording head 1 that has moved in the direction of arrow F from the recovery position P on the movement path, thereby reducing the ejection of the recording head 1. Exit side! Ink and foreign matter X adhering to a (including those adhering as marks on the rubber cap 11a during operation of the head recovery device 11).
is removed (see Figure 2, μ-tei).

When the moving means 5 moves the cleaning member 4 to the retracted position, the solenoid 9 is de-energized and the holder 6 is moved in the direction indicated by the arrow by the tensile force of the spring 10. The cleaning member 4 held by the holder 6 is
The cleaning member 4 is stopped at the retracted position by coming into contact with the second stopper surfaces 4g and 4h of the cleaning member 4 and the second fixing surfaces 7g and 7h of the second fixing members 7e and 7f, respectively. At this time, as in the conventional moving means, the lower end (as shown in the figure) of the circumferential surface of the second cylindrical portion 6b and the inner wall of the guide hole 7b (
Figure 1).

To describe the effects of this embodiment, when the first stopper surface 4d formed integrally with the cleaning member 4 made of an elastic body comes into contact with the first fixing surface 7d, and when each Second stopper surface 4g, 4h
comes into contact with each of the second fixed surfaces 7g and 7h,
The first stopper surface 4d and each second stopper surface 4g, 4h
acts as a buffer material to soften the impact of each contact, so
The contact noise generated from the moving means 5 is reduced. As a result, the recording device can be made quieter.

In addition, instead of providing a new cushioning material as a separate part to reduce contact noise, the shape of the cleaning member made of an elastic body is changed and used as a cushioning material, and the side wall of the moving means is adjusted accordingly. Since the shape can be changed, the increase in manufacturing costs can also be kept to a minimum.

At this point, a second embodiment will be explained.

In FIG. 4, a carriage 22 on which a recording head 21 is mounted has a structure similar to that of the first embodiment.
It is reciprocated in a direction perpendicular to the paper plane of the figure along a recording medium (not shown) that is conveyed so as to face the ejection port surface 21a of No. 1. The recording head 21 is configured to perform recording on the recording medium by ejecting ink from its ejection openings while being moved along the recording medium, and covers a recording area on the moving path. It is shown that the vehicle is stopped at a predetermined position outside the range of .

A holter 26 that clamps a cleaning member 24, which will be described later, has a first stop position S on one end side of the ejection port surface 21a of the recording head 21 stopped at the predetermined position and a second stop position T on the other end side. The cleaning member 24 is attached to a known moving means (not shown) that linearly reciprocates the cleaning member 24 in a direction parallel to the discharge port surface 21a (in the direction of the arrow G).

The cleaning member 24 is a plate-shaped member made of an elastic body similar to that of the first embodiment, and has a rectangular first protrusion 24a and a second protrusion 24c integrally formed on both sides thereof. ing. The first protrusion 24a passes through a hole bored in the holster 26 in the same direction as the direction from the second stop position T to the first stop position S, and protrudes outward from the holster 26 by an appropriate length. The first stopper surface 24b, which is the protruding end surface, serves as a first stopper portion. The second protrusion 24c moves from the first stop position S to the second
The second stopper surface 2 is a second stopper surface 2 that passes through a hole drilled in the holter 26 and protrudes outside the holter 26 by an appropriate length in the same direction as the direction toward the stop position T of the holster 26 .
4d is a second stopper portion.

The first fixing member 27 and the second fixing member 28 are fixed to the main body (not shown) of the recording apparatus, and are respectively positioned at appropriate positions on both ends of the ejection port surface 21a of the recording head 21 stopped at the predetermined position. are doing. Said first fixing member 2
7 is formed with a first fixing surface 27a that faces the first stopper surface 24b of the cleaning member 24, and the second
A second fixing surface 28a facing the second stopper surface 24d of the cleaning member 24 is formed on the fixing member 28.

To explain the operation when the cleaning member 24 is reciprocated by the moving means, the cleaning member 24 is moved to the first stop position S by the moving means and the first stop surface 24b of the cleaning member 24 is moved.
and the first fixing surface 27a of the first fixing member 27 come into contact with each other, so that the cleaning member 24 is stopped at the first stop position S, and is moved by the moving means to the second stop position T, and the second fixing member 24 is moved to the second stop position T. When the stopper surface 24d and the second fixing surface 28a of the second fixing member 28 come into contact with each other, the second fixing member 28 is stopped at the second stop position T.

During the reciprocating movement between the first stop position S and the second stop position T, the tip of the cleaning member 24 rubs against the ejection port surface 21a of the recording head 21, thereby cleaning the ejection port surface 21a. Ink and foreign matter adhering to the paper are removed.

The moving means of this embodiment is for linearly reciprocating the cleaning member 24 in the direction of arrow G between the first stop position S and the second stop position T. Alternatively, the cleaning member may be configured to rotate along an arc of an appropriate radius.

Further, a cleaning member having a first and second stopper portion, a first fixing member, a second fixing member, and a moving means having the same configuration as in this embodiment are arranged such that an ejection port is formed over the entire width of the recording area of the recording medium. The present invention may also be applied to a recording apparatus equipped with a full-line type recording head.

In each of the cleaning members shown in the above-mentioned embodiments, the first protruding part and the second protruding part are formed respectively, and one surface thereof is used as the first stopper part and the second stopper part, respectively. There is no need to form a protrusion,
The first stopper part may be formed in an appropriate shape to correspond to the first fixing member, and the second stopper part may be formed in an appropriate shape to correspond to the second fixing member. The material of the cleaning member may be an elastic material or a porous material capable of absorbing ink.

An example of a recording head equipped with an electrothermal converter used in each of the above embodiments will now be described. As shown in FIG. 5, the recording head 41 has an electrothermal transducer 41c that is supplied with an applied voltage and generates a thermal energy key in order to eject ink from a plurality of ejection ports 41b provided in a row.
are arranged for each liquid path. By applying a drive signal, the electrothermal converter 41c generates thermal energy to cause film boiling and form bubbles in the liquid path. As the bubbles grow, each of the discharge ports 41b
The structure is such that ink is ejected from the ink.

The present invention brings about excellent effects particularly in inkjet recording systems, such as Hubble-shot force type recording heads and recording apparatuses proposed by Canon Corporation.

As for typical configurations and principles thereof, it is preferable to use the basic principles disclosed in, for example, US Pat. No. 4,723,129 and US Pat. No. 4,740,796. Is this method applicable to the so-called on-demand type and continuous type chairs? In particular, in the case of the on-demand type, is it compatible with the sheet holding the liquid (ink) and the liquid path? By applying at least one drive signal that corresponds to recorded information and causes a rapid temperature rise exceeding nucleate boiling to the disposed electrothermal transducer, the electrothermal transducer generates a thermal energy key, and the recording is performed. This method is effective because it causes film boiling on the heat acting surface of the head, resulting in the formation of bubbles in the liquid (ink) in one-to-one correspondence with this drive signal. The growth and contraction of the bubble causes liquid (ink) to be ejected through the ejection opening to form at least three droplets. It is more preferable to use this drive signal in a pulse form, since the growth and contraction of bubbles can be carried out immediately and appropriately, and liquid (ink) can be ejected with particularly excellent responsiveness. Suitable pulse-shaped drive signals include those described in U.S. Pat. No. 4,463,359 and U.S. Pat. No. 4,345,262. Incidentally, U.S. Patent No. 431 for the invention regarding the temperature increase rate of the heat acting surface
If the conditions described in specification No. 3124 are adopted,
It is possible to make even better records.

The configuration of the recording head includes, in addition to the combined configuration of ejection ports, liquid paths, and electrothermal converters (straight liquid flow path or right-angled liquid flow path) as disclosed in the above-mentioned specifications, a heat acting section. US Pat. No. 4,558,333 and US Pat. No. 4,459,600 disclose a configuration in which the
The present invention is also effective in a structure using the specification of the above specification.

In addition, Japanese Patent Application Laid-open No. 123670 of 1982 discloses a configuration in which a common slit is used as a discharge part for a plurality of electrothermal converters, and a hole that absorbs pressure waves of thermal energy is disclosed. The present invention is also effective as a configuration based on Japanese Patent Application Laid-Open No. 138461 of 1981, which discloses a configuration in which the discharge portion corresponds to the discharge portion.

Furthermore, as a full-line type recording head whose length corresponds to the width of the maximum recording medium that can be recorded by the recording device, the length can be increased by combining multiple recording heads as disclosed in the above-mentioned specification. The present invention can more effectively exhibit the above-mentioned effects, regardless of whether the configuration satisfies the above requirements or the configuration is configured as a single recording head formed integrally.

In addition, a replaceable chip-type recording head that is attached to the recording device body enables electrical connection to the recording device body and ink supply from the recording device body, or a chip-type recording head that is attached to the recording head itself. The present invention is also effective when a cartridge type recording head is used.

Further, it is preferable to add a recovery means, a preliminary auxiliary means, etc. for the recording head, which are provided as a configuration of the recording apparatus of the present invention, since this further stabilizes the effects of the present invention. Specifically, these include means for pressurizing the recording head, preheating means using an electrothermal transducer or a separate heating element, or a combination thereof, and a preliminary ejection other than recording. Using ejection mode is also effective for stable recording.

Furthermore, the recording mode of the recording device is not limited to a recording mode for only mainstream colors such as black, but may also include a recording head that is configured integrally or a combination of multiple heads, multiple colors of different colors, or a mixture of colors. The present invention is also extremely effective for recording apparatuses equipped with at least one full color image.

In each of the embodiments of the present invention described above, the ink is explained as a liquid, but it is an ink that solidifies at room temperature or lower, and is softened or liquid at room temperature, or in the above-mentioned inkjet, the ink itself is heated at 30°C. Since it is common to adjust the temperature within the range of 70°C or less so that the viscosity of the ink is within the stable ejection range,
Any material may be used as long as it is in an ink or liquid state when the recording signal is applied. In addition, it is possible to actively prevent temperature rise due to thermal energy by using it as energy to transform the ink from a solid state to a liquid state, or to use ink that solidifies when left in order to prevent ink evaporation. In any case, ink may be liquefied by applying thermal energy in response to a recording signal and ejected as liquid ink, or it may already begin to solidify by the time it reaches the recording medium. The use of ink that is liquefied only by energy is also applicable to the present invention. In such a case, the ink is held in a liquid or solid state in the recesses or through holes of the porous sheet, as described in JP-A-54-56847 or JP-A-60-71260. It may also be in a form that faces the electrothermal converter. In the present invention, the most effective method for each of the above-mentioned inks is to implement the above-mentioned film boiling method.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

The first stopper part and the second stopper part, which are integrally formed on the cleaning member made of an elastic body, have the function of cushioning material to soften the impact of each contact when abutting against the first fixing member and the second fixing member, respectively. Therefore, the contact noise generated from the moving means is reduced, and as a result, the inkjet recording apparatus can be made quieter.

Further, the first stopper part and the second stopper part are not newly provided as separate parts, but are formed integrally with the cleaning member, taking into account that the cleaning member is made of an elastic body. Compared to the example, the configuration is simpler and the increase in manufacturing costs can be kept to a minimum.
