TECHNICAL FIELD OF THE INVENTION
The present invention relates to an ink jet recording apparatus, and more particularly, comprises an ink jet recording head mounted on a carriage that moves in the width direction of a recording sheet and ejecting ink droplets from nozzle openings to form an image on a recording medium, The present invention relates to an ink jet recording apparatus in which a flushing area for receiving an ink droplet when a flushing drive signal is supplied to a recording head is arranged outside a print area.
[0002]
[Prior art]
2. Description of the Related Art Ink jet recording apparatuses have been used in many types of printing including color printing in recent years because noise during printing is relatively small and small dots can be formed with high density. Such an ink jet recording apparatus includes an ink jet recording head that receives supply of ink from an ink cartridge, and a paper feeding unit that moves recording paper relative to the recording head, and moves the recording head on a carriage. Recording is performed by ejecting ink droplets onto the recording paper while moving in the width direction of the recording paper. The carriage is equipped with a recording head that can eject black ink and each color ink of yellow, cyan, and magenta, and not only text printing with black ink, but also full-color printing by changing the ejection ratio of each ink. It is possible.
[0003]
Since the ink jet recording head discharges the ink pressurized in the pressure generating chamber from the nozzles as ink droplets onto the recording paper to perform printing, the ink viscosity increases due to evaporation of the solvent from the nozzle opening, and There is a problem that printing is poor due to solidification of the toner, adhesion of dust, and mixing of air bubbles.
[0004]
For this purpose, the ink jet recording apparatus is provided with capping means for sealing the nozzle openings of the recording head during non-printing, and a cleaning device for cleaning the nozzle plate if necessary. This capping means not only functions as a lid for preventing drying of the ink in the nozzle openings when printing is stopped, but also when the nozzle openings are clogged, the nozzle plate is sealed by the capping means, It also has a function of sucking ink from the nozzle openings by the negative pressure from the suction pump to eliminate clogging due to solidification of the ink in the nozzle openings and ink ejection failure due to air bubbles entering the ink flow path.
[0005]
Forcible suction and discharge of ink to eliminate clogged recording heads and air bubbles in the ink flow path is usually called a cleaning operation. Or when the user operates the cleaning switch in order to eliminate the deterioration of the quality of the recorded image, and after the ink is discharged by negative pressure, the wiping member made of an elastic plate such as rubber is used. This is a process that involves a wiping operation on the head surface.
[0006]
It also has a function to apply a drive signal unrelated to printing to the recording head to eject ink droplets.This is usually called a flushing operation, and is performed by wiping or the like during the cleaning operation near the nozzle opening of the recording head. For the purpose of recovering irregular meniscus, discharging and discharging mixed color ink that has flowed backward from the nozzle by wiping, and preventing clogging due to thickening of ink at the nozzle opening where the amount of ink droplets discharged during printing is small. This operation is performed at regular intervals.
[0007]
Next, an outline of the configuration of an ink jet recording apparatus capable of performing the flushing operation and the cleaning operation as described above will be described with reference to FIG.
[0008]
In FIG. 6, reference numeral 1 denotes a carriage, which reciprocates while being guided by a horizontally disposed carriage shaft 4 supported by left and right frames 2 and 3 via a timing belt driven by a carriage motor (not shown). It is configured to be. An ink jet type recording head 5 is mounted on the carriage 1 downward, and a black ink cartridge 6 for supplying ink to the recording head 5 and a color ink cartridge 7 are removably mounted on an upper portion thereof. Have been. A paper guide member 8 is arranged below the recording head 5 corresponding to the scanning direction, and a recording paper 9 as a recording medium is placed on the paper guide member 8, and the recording paper 9 is not shown. It is configured to be moved in a direction perpendicular to the scanning direction of the recording head 5 by a paper feeding unit.
[0009]
Reference numeral 10 in the figure denotes capping means arranged in a non-printing area (home position), which seals a nozzle plate as a nozzle forming surface of the recording head 5 when the recording head 5 moves directly upward. It is configured to be able to. A suction pump 11 for applying a negative pressure to the internal space of the capping unit 10 is disposed below the capping unit 10. The capping means 10 functions as a lid for preventing the nozzle openings of the recording head 5 from drying during the suspension period of the recording apparatus, and also acts on the recording head 5 by applying a negative pressure from the suction pump 11 to remove ink. It also has a function as a suction means.
[0010]
A wiping member 12 made of an elastic plate or the like such as rubber is disposed near the capping unit 10. When the carriage 1 reciprocates toward the capping unit 10, the nozzle forming surface of the recording head 5 is formed. Is configured to perform a wiping operation of wiping.
[0011]
On the other hand, a flushing area 13A is formed in the other non-printing area facing the capping unit 10 via the central printing area. The flushing area 13 is constituted by an opening 13 a formed in the paper guide member 8. An ink absorbing material 14 which is also used as a member for absorbing and holding the ink sucked and discharged by the capping means 10 and the suction pump 11 is arranged at the inner bottom portion (forward) of the opening hole 13a. Reference numeral 14 denotes an ink absorbing material storage case arranged along the paper guide member 8, that is, a waste ink tank 15.
[0012]
[Problems to be solved by the invention]
By the way, in the conventional ink jet apparatus, when a predetermined time elapses during printing, the recording head 5 is moved to the capping unit 10 to perform so-called flushing in which ink is ejected from nozzle openings. .
[0013]
In order to perform this flushing operation, it is necessary to temporarily suspend printing, move the carriage to the capping unit 10, discharge ink, return the carriage to the print suspension position, and resume printing. Therefore, there is a technical problem that the throughput decreases due to the flushing operation and the printing time is increased. In particular, when the flushing operation is performed when the recording head 5 is located in the printing area on the opposite side of the capping unit 10, the carriage must once move to the capping unit 10, and the carriage in the flushing operation is not used. The put drop was remarkable.
[0014]
Further, the ink absorbing material 14 needs to be provided at a position facing the flushing area 13A in order to receive the ejection of ink from the recording head. However, the ink absorbing material 14 faces the flushing area 13A due to the arrangement of other components. It may not be possible. There is also a demand that the ink absorbing material must be made smaller in order to reduce the size of the entire apparatus.
[0015]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned technical problem, and has as its first object to provide an ink jet recording apparatus capable of suppressing a decrease in throughput during a flushing operation.
[0016]
It is a second object of the present invention to provide an ink jet recording apparatus capable of receiving ink ejection from a recording head without providing an ink absorbing material at a position facing a flushing area. is there.
[0017]
[Means for Solving the Problems]
An ink jet recording apparatus according to the present invention, which has been achieved to achieve the above-described object, is mounted on a carriage that moves in the width direction of recording paper, and forms an image on a recording medium by discharging ink droplets from nozzle openings. A flushing area for receiving ink droplets when a flushing drive signal is supplied to the recording head, a non-printing area on the capping unit side sealing the recording head, and a central printing area. And provided in the other non-printing area facing the capping means.
[0018]
As described above, the flushing area for receiving the ink droplets when the flushing drive signal is supplied to the recording head, the non-printing area on the capping unit side sealing the recording head, and the capping unit via the central printing area. When the flushing operation is performed, the carriage can be moved to any closer flushing region to discharge ink when the flushing operation is performed. Further, since the flushing area is provided on the capping unit side, it is not necessary to return to the capping unit and perform flushing. As a result, the throughput in the flushing operation is improved, and the printing time is shortened.
[0019]
Here, it is preferable that the flushing area has an opening formed in the paper guide member and an ink absorbing material disposed in front of the opening. Since the opening holes are provided, the ink ejected from the nozzle openings of the recording head does not scatter, and the ejected ink is absorbed by the ink absorbing material.
[0020]
In addition, one or both of the flushing area of the non-printing area on the side of the capping unit that seals the recording head and the flushing area of the other non-printing area facing the capping unit via the central printing area. It is desirable to form a slope member that guides ink droplets to the ink absorbing material in the region between the opening hole and the ink absorbing material.
[0021]
As described above, by forming the slope member between the opening hole and the ink absorbing material, the ink ejected from the nozzle opening of the recording head once adheres to the slope portion of the slope member, and then becomes the ink absorbing material. Is led to. Therefore, the ink absorbing member does not necessarily need to be provided at a position facing the flushing area, and since it is another, the degree of freedom in arranging other components can be increased.
[0022]
Further, an ink jet recording apparatus according to the present invention, which has been made to achieve the above object, is mounted on a carriage that moves in the width direction of a recording sheet, and ejects ink droplets from nozzle openings to form an image on a recording medium. An ink jet recording head for forming a recording head is provided in at least one of the non-printing area on the capping unit side sealing the recording head and the other non-printing region facing the capping unit via the central printing region. It is desirable to form an inclined surface member that receives the ink droplets when the flushing drive signal is supplied to the recording head and guides the attached ink droplets to the ink absorbing material.
[0023]
As described above, by forming the slope member in at least one of the flushing area of the non-printing area on the capping unit side and the flushing area of the other non-printing area facing the capping unit, the nozzle of the recording head The ink discharged from the opening once adheres to the slope of the slope member, and is then guided to the ink absorbing material. Therefore, the ink absorbing member does not necessarily need to be provided at a position facing the flushing area, and since it is another, the degree of freedom in arranging other components can be increased. In addition, the size of the ink absorbing material can be reduced, and the size of the entire apparatus can be reduced.
[0024]
Here, it is desirable to have an opening hole formed in the paper guide member between the recording head and the slope member for guiding the ink droplets to the ink absorbing material. With such an opening, it is possible to prevent the ink from scattering.
[0025]
Further, it is desirable that the inclination direction of the inclined surface portion of the inclined member is formed parallel or perpendicular to the moving direction of the carriage, or at a predetermined angle.
[0026]
It is preferable that the inclination angle θ of the slope portion of the slope member is in the range of 30 ° <θ <60 °. As the inclination angle θ of the slope becomes closer to 0 °, ink may adhere to the slope and may not fall in the direction of the ink absorbing material. Therefore, the inclination angle θ of the slope is preferably 0 ° or more. Further, as the inclination angle θ of the slope becomes closer to 90 °, the size of the ink absorbing material cannot be reduced, and it is necessary to provide the ink absorbing material at a position facing the flushing region 13. Therefore, the inclination angle θ of the slope is preferably 60 ° or less.
[0027]
Therefore, it is preferable to apply the inclination angle θ of the slope portion of the slope member within the range of 30 ° <θ <60 °.
[0028]
It is preferable that a water-repellent treatment layer is formed on the slope. By forming the water-repellent treatment layer on the slope as described above, the ink attached to the slope is easily dropped in the direction of the ink absorbing material in the form of ink droplets, and the attached ink is solidified on the slope. Can be prevented. Further, by forming the water-repellent treatment layer, the inclination angle θ of the slope portion can be made smaller, and as a result, the size can be further reduced.
[0029]
Further, it is desirable that the size and shape of the opening be larger than the nozzle plate of the recording head. In this way, by forming the size and shape of the opening hole larger than the nozzle plate of the recording head, the ink ejected from the nozzle opening of the recording head does not scatter, but passes through the opening hole and is finally formed. Is absorbed by the ink absorbing material.
[0030]
Further, the recording head is a recording head that discharges a plurality of colors, and a first ink that is discharged from a nozzle opening corresponding to a low position of a slope portion of a slope member is discharged by a nozzle opening corresponding to an upper portion of the slope portion. It is preferable that the second ink has a property that the second ink is more easily deposited on the slope than the second ink.
[0031]
Thus, even if the first ink discharged from the nozzle opening corresponding to the low position of the slope portion has a property of easily depositing on the slope portion, the second ink which is hardly solidified and adheres to the upper portion of the slope portion As a result, the ink drops downward without being solidified and is absorbed by the ink absorbing material. In particular, it is preferable that the first ink is a black ink.
[0032]

It is defined by the hole 13b.
[0035]
The ink absorbing material 14 housed in the waste ink tank 15 is disposed at the front (inner bottom) of the opening 13b. That is, the ink that has been idlely discharged from the recording head in the flushing area 13A and the flushing area 13B is configured to be absorbed by the ink absorbing material 14 contained in the waste ink tank 15.
[0036]
Next, a control circuit of the recording apparatus having the above configuration will be described with reference to FIG.
[0037]
In FIG. 2, reference numeral 30 denotes print control means, which generates bitmap data based on print data from a host computer of the printing apparatus, generates a drive signal by a head drive means 31 based on the data, and performs printing. The ink is ejected from the head 5. The head driving means 31 receives a flushing command signal from the flushing control means 32 and outputs a drive signal for a flushing operation to the recording head 5 in addition to the drive signal based on the print data. Is also configured to be able to perform the ejection of the ink.
[0038]
Reference numeral 33 denotes a cleaning control unit. The pump driving unit 34 is operated by a command from the cleaning control unit 33, and the suction pump 11 is driven and controlled. The cleaning control unit 33 is configured to be supplied with a command signal from the print control unit 30 and the cleaning command detection unit (CL command detection unit) 35. A command switch 36 is connected to the cleaning command detecting means 35. When the user pushes the switch 36, the command detecting means 35 is operated to execute a manual cleaning operation. Have been.
[0039]
A carriage position control means 37 is connected to the flushing control means 32. At the time of a flushing operation, a control signal is sent to the carriage position control means 37, and a carriage motor 38 is driven to be loaded on the carriage 1. The recording head 5 is controlled to be moved to the flushing areas 13A and 13B.
[0040]
At this time, whether the recording head 5 mounted on the carriage 1 is moved to the flushing area 13A or the flushing area 13B is determined in consideration of the distance from the recording head 5 in the printing area or the printing direction. -The flushing control means 32 sends a control signal to the carriage position control means 37 so as to move it to the area where the put does not decrease.
[0041]
Further, a fan drive control means 39 is connected to the flushing control means 32, and sends a control signal to the fan drive control means 39 at the time of a flushing operation to suppress a rise in temperature in the recording apparatus. The driving of the fan motor 40 for driving the exhaust fan (not shown) is controlled so as to be temporarily stopped.
[0042]
As described above, the flushing areas 13A and 13B for receiving the ink droplets when the flushing drive signal is supplied to the recording head 5 include the non-printing area on the capping unit side for sealing the recording head and the central printing area. And the other non-printing area facing the capping means is provided so as to move the recording head 5 to an area that does not reduce the throughput in the flushing operation. Such an adverse effect can be prevented.
[0043]
Next, a second embodiment of the ink jet recording apparatus according to the present invention will be described with reference to FIGS. FIG. 3 shows the configuration of a recording apparatus main body to which the second embodiment according to the present invention is applied, and FIG. 4 is an enlarged view of the flushing area shown in FIG. 3 and 4, the same or corresponding members as those shown in FIG. 6 are denoted by the same reference numerals, and detailed description thereof will be omitted. The control circuit of the device is the same as the control circuit shown in FIG.
[0044]
In the second embodiment, as shown in FIG. 3, the openings 13a and 13b formed in the paper guide member 8 provided in the flushing areas 13A and 13B, and the front of the openings 13a and 13b ( It is characterized in that a slope member 20 having a slope portion 20a inclined toward the print area is formed between the ink absorbing member 14 and the ink absorbing member 14 disposed at the inner bottom portion.
[0045]
That is, by providing a slope member 20 inclined toward the print area between the ink absorbing member 14 disposed at the inner bottom of the opening holes 13a and 13b, the ink ejected from the recording head 5 can pass through the opening holes 13a and 13b. After passing through 13a and 13b, it adheres to the slope portion 20a of the slope member 20. When the ink adheres to the slope 20 to some extent, the ink drops and falls in the direction of the ink absorbing material 14, and the ink is absorbed by the ink absorbing material 14.
[0046]
As described above, the slope member 20 inclined toward the print area is provided between the opening 13a and the ink absorbing member 14 disposed at the front (inner bottom) of the opening 13b, and the ink ejected from the recording head 5 is inclined. Since the ink absorbing member is configured to be guided to the ink absorbing member via the member 20, it is not necessary to provide the ink absorbing member at a position facing the flushing regions 13A and 13B. Therefore, there is little restriction on the arrangement of other components, and the degree of freedom in device design can be increased. Further, the ink absorbing member can be arranged smaller in the center of the apparatus, and the size of the entire apparatus can be reduced.
[0047]
Although FIG. 3 shows an example in which the slope member 20 is formed in both of the flushing areas 13A and 13B, the slope member 20 is not necessarily provided in both, and may be provided in one of the flushing areas.
[0048]
Further, the slope portion may be formed integrally with the opening holes 13a and 13b of the paper guide member 8.
[0049]
The slope angle θ of the slope portion 20a of the slope member 20 can be applied in a range of 0 ° <θ <90 °. However, as the inclination angle θ of the slope 20a approaches 0 °, ink may adhere to the slope 20a and may not fall in the direction of the ink absorbing material 14. Therefore, the inclination angle θ of the slope 20a is preferably 30 ° or more.
[0050]
Further, as the inclination angle θ of the slope 20a approaches 90 °, the size of the ink absorbing material 14 cannot be reduced. Therefore, it is necessary to provide the ink absorbing material 14 at a position facing the flushing regions 13A and 13B. It is preferable to apply the inclination angle θ of the slope portion 20a in the range of 30 ° <θ <60 °.
[0051]
Further, it is preferable that a water repellent such as silicone, fluorine, and Teflon is coated on the slope 20a. By forming the water-repellent treatment layer on the slope 20a in this manner, the ink adhering to the slope 20a tends to drop in the direction of the ink absorbing material 14 in the form of ink droplets. 20a can be prevented from being solidified. Further, since the water-repellent treatment layer is formed on the slope portion 20a, even if the slope angle θ of the slope portion 20a is small, the ink adhering to the slope portion 20a becomes in the form of ink droplets and is directed toward the ink absorbing material 14. Therefore, the ink absorbing material 14 can be made smaller.
[0052]
The inclination direction of the slope portion 20 of the slope member 20 is formed in parallel with the movement direction of the carriage 1 as shown in FIGS. 3 and 4, but, for example, as shown in FIG. (Perpendicular to the plane of FIG. 5), or may be formed at a predetermined angle with the moving direction of the carriage 1.
[0053]
By changing the inclination direction of the slope portion 20a in this manner, the degree of freedom of arrangement of the ink absorbing material can be increased.
[0054]
Further, as shown in FIG. 4, it is preferable that the size and shape l of the opening holes 13a and 13b are larger than the size and shape L of the nozzle plate of the recording head. By making the size and shape l of the opening holes 13a and 13b larger than the nozzle plate 5a of the recording head 5, the ink discharged from the nozzle opening of the recording head 5 does not scatter, and The ink passes through the holes 13a and 13b and is absorbed by the ink absorbing material 14.
[0055]
Further, it is desirable that the recording head 5 is provided at a position corresponding to a low position of the inclined portion 20 with a nozzle opening from which ink that is easy to dry and solidify (having a high viscosity) is discharged. For example, it is desirable to use the nozzle opening 5b or the nozzle opening 5c as a nozzle opening for discharging black ink. In other words, it is desirable to use at least the nozzle openings 5d as yellow, cyan, and magenta nozzle openings other than the black ink.
[0056]
The black ink exemplified above has a higher ratio of the dye component than yellow, cyan, and magenta, has a large increase in viscosity when the solvent is volatilized, and is easily solidified. Therefore, if black ink adheres to a high position on the slope 20a, the black ink may solidify on the slope 20a. On the other hand, even if the black ink adheres to the middle and low positions of the slope portion 20a, the black ink does not solidify due to the fall of the ink attached to a higher position, but falls down the slope portion 20a and absorbs the ink. Absorbed by material 14. The above-described black ink is an example, and may be another ink that is easily dried and solidified (has a high viscosity).
[0057]

Since it is provided in the printing area and the other non-printing area facing the capping means via the central printing area, the throughput in flushing does not decrease and the printing time by the flushing operation takes time. Can be prevented.
[0058]
In addition, the ink jet recording apparatus according to the present invention is provided with a slope member in the flushing area and configured to guide the ink discharged from the recording head to the ink absorber through the slope member.
