Description

[Technical field]

[0001] The present invention relates to a recording device for drying a recording liquid on a recording medium. [Background technology]

[0002] It is desirable for a liquid ejection type recording device, such as an inkjet recording device, to have the ability to print high-quality images on a recording medium even in a low-temperature or high-temperature surrounding environment. However, for example, in a low-temperature environment, so-called water-based ink, which is used as a recording liquid, is difficult to dry on the recording medium after ejection, which may adversely affect print quality. In recent years, in response to such print quality problems, it has been proposed to install a print zone blowing mechanism for drying the ink on the recording medium (Patent Document 1). The print zone blowing mechanism blows air onto the recording medium, thereby promoting the drying of the ink immediately after the ink is dropped onto the recording medium. This makes it possible to suppress deterioration of print quality. [Prior art documents] [Patent documents]

[0004] However, parts such as pinch rollers are mounted between the printing area and the air blowing nozzles, and if the surfaces of these parts are uneven or have holes, the air blowing may be disturbed, causing the air blowing to become less uniform. If the air blowing becomes less uniform, the drying of the recording medium may differ depending on the location, causing uneven drying and deteriorating image quality.

[0005] An object of the present invention is to provide a technique that enables uniform drying of a recording liquid on a recording medium. [Means for solving the problem]

[0009] Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings. The dimensions, materials, shapes, and relative positions of the components described in the embodiment may be changed as appropriate depending on the configuration of the device to which the invention is applied and various conditions. In other words, the scope of the present invention is not limited to the following embodiment.

[0010] First Embodiment An overview of the entire recording apparatus according to the first embodiment of the present invention will be described with reference to Figures 1 and 2. Here, as an example of the recording apparatus 1 according to the first embodiment of the present invention, a liquid ejection type recording apparatus (inkjet recording apparatus) that ejects ink as a recording liquid onto a recording medium to record an image or the like on the recording medium will be described.

[0011] Fig. 1 is a schematic perspective view showing the general configuration of the recording unit and its periphery in a recording device according to this embodiment. Fig. 2 is a schematic cross-sectional view of Fig. 1 taken along a direction (Y direction and Z direction) perpendicular to an X direction parallel to a main scanning direction in a recording operation. First, a configuration common to all the embodiments will be described.

[0012] In addition, in Fig. 1, Fig. 2, Fig. 3 and the following figures, the X direction is the direction along the main scanning direction (the direction of reciprocating movement of the recording head) in the recording operation, as described above, and is the width direction of the recording medium. The Y direction is the direction along which the recording medium is transported, i.e., the sub-scanning direction. Furthermore, the Z direction is the direction along the vertical direction (the direction of gravity), and is the direction perpendicular to the recording surface of the recording medium. The arrangement of the recording device 1 in each figure is based on the assumption that the device is installed on an installation surface that is horizontal to the vertical direction, which is the normal usage state of the device.

[0013] 1 and 2, the recording device 1 is equipped with a roll-shaped recording medium (roll sheet) 2. The recording medium 2 is fed onto an upstream platen 12 by a feeding means (not shown), and then sandwiched between a conveying roller 5 and a pinch roller (roller) 6, which are a pair of conveying members constituting the conveying means. The pinch roller 6, which serves as both a conveying member and a pressing member, holds the recording medium 2 by pressing the recording medium 2 toward the conveying roller 5 by receiving the biasing force of a spring (not shown).

[0014] From the viewpoint of moldability, it is difficult to manufacture the pinch roller 6 as a single member having a size corresponding to the width of the recording medium 2 along the main scanning direction, so a configuration is adopted in which the pinch roller 6 is divided into multiple parts and arranged in the main scanning direction. That is, multiple pinch rollers 6 as pressing members are provided lined up in the main scanning direction, and each pinch roller 6 is supported by a pinch roller holder 7 so as to be rotatable about a rotation axis along the main scanning direction. Multiple pinch roller holders 7 as supporting members are also provided lined up in the main scanning direction corresponding to the pinch rollers 6. Therefore, gaps in the main scanning direction are generated between the multiple pinch rollers 6 and the multiple pinch roller holders 7 arranged lined up in the main scanning direction.

[0015] The pinch roller holder 7 is provided so as to extend from the upstream side in the transport direction of the recording medium 2 toward the recording area where the recording head 3 and the recording medium 2 supported by the platen 11 face each other, and rotatably supports the pinch roller 6 at its tip end. The pinch roller holder 7 has a rotation shaft 7c aligned in the direction and is configured to be swingable around the rotation shaft 7c. The pinch roller holder 7 can move the pinch roller 6 toward and away from the conveying roller 5 by swinging around the rotation shaft 7c.

[0016] The recording medium 2 is sandwiched between the transport roller 5 and the pinch roller 6, and as the transport roller 5 rotates, the recording medium 2 is transported onto the platen 11 (in the direction of arrow A) by frictional force generated in the portion sandwiched between the transport roller 5 and the pinch roller 6. Since the recording medium 2 is transported by being sandwiched between the transport roller 5 and the pinch roller 6, the length of the recording medium 2 in the width direction (X direction) (the length in the direction intersecting the transport direction) needs to be equal to or less than the width of the transport roller 5 and the pinch roller 6.

[0017] A recording head 3 and a carriage 4 that holds the recording head 3 are provided above the platen 11. The carriage 4 is supported by a frame 10, a main rail 8, and a sub-rail 9, each of which is provided to extend in the X direction. The carriage 4 is also connected to a carriage motor 21 (see FIG. 6) via a belt 16. The carriage 4 is pulled by the connected belt 16 as the carriage motor 21 rotates in the forward and reverse directions, and reciprocates over the platen 11 along the main rail 8, which serves as a guide rail (in the direction of arrow B).

[0018] The recording medium 2 transported onto the platen 11 is recorded on by ink ejected from an ejection port array formed on an ejection port surface 3a of a recording head 3 mounted on a carriage 4 as the carriage 4 moves back and forth over the recording medium 2. When recording is performed, air is blown onto the recording medium 2 transported onto the platen 11 from an air blowing unit 100 as an air blowing means, accelerating the drying of the ink recorded on the recording medium 2.

[0019] The air blowing unit 100 is composed of an air blowing fan 101, an air blowing duct 103, an air blowing nozzle 104, and an air blowing guide plate 105. The air generated by the air blowing fan 101 as an air blowing source passes through an air passage formed by the air blowing duct 103 as an air passage member and the air blowing nozzle 104 connected to the air blowing duct 103. With this configuration, the air blowing unit 100 supplies air to the recording medium 2 (recording area) (arrow C). In addition, in order to further promote drying of the ink, a heater 102 is provided downstream of the air blowing fan 101, which makes it possible to add heat to the air supplied from the air blowing fan 101, and the air supplied to the recording medium 2 can be made into warm air.

[0020] The air blowing nozzle 104 is provided above the pinch roller holder 7 and the upstream platen 12 as support members for the pinch roller 6, and below the main rail 8 and the frame 10. An exhaust port (air blowing port) 104c of the air blowing nozzle 104 is disposed downstream of the main rail 8 and upstream of the transport roller 5 and the pinch roller 6 in the transport direction (arrow A direction or Y direction) of the recording medium 2. The air blowing nozzle 104 is provided with a shape that faces downward as it proceeds downstream in the transport direction, in order to blow air mainly to the portion of the recording medium 2 supported by the platen 11 (supported region 2a, see FIG. 3, etc.). As a result, the air blowing from the air blowing port 104c is configured to face the transport direction of the recording medium 2 supported by the platen 11.

[0021] 1, the air blowing nozzles 104 are arranged at equal intervals along the reciprocating direction (arrow B direction, X direction) of the recording head 3 (carriage 4). Depending on the reciprocating position of the recording head 3, some of the air blowing nozzles 104 face the recording head 3 (carriage 4) in the transport direction A (Y direction) of the recording medium 2.

[0022] After the recording and drying are completed, the recording medium 2 is conveyed by the conveying rollers 5. The wafer is then transported to the downstream platen 13 and discharged outside the apparatus.

[0023] FIG. 6 is a block diagram for explaining an example of the configuration of a control system in the recording device 1. The CPU 42 controls each part of the recording device 1, including the carriage motor 21, the paper feed motor 22, and the transport motor 23, according to a control program stored in the ROM 41. Various setting information such as the type and width of the recording medium 2 and the set temperature of the heater 102 is input to the CPU 42 from the operation panel 30 via the input interface 31. The CPU 42 also writes and reads information related to the recording medium 2 to the RAM 40. The carriage motor 21, the paper feed motor 22, the transport motor 23, the recording head 3, the blower fan 101, and the heater 102 are output-controlled by the CPU 42 based on the temperature detected by the heater temperature sensor 24 and the specified value written in the ROM 41. That is, the CPU 42 controls the scanning of the carriage 4, the transport of the recording medium 2, and the driving of the heater 102 and the blower fan 101.

[0024] The configuration around the blower nozzle 104 of the recording apparatus 1 of this embodiment will be described in more detail with reference to Fig. 3(a) to Fig. 3(c). Fig. 3(a) to Fig. 3(c) are diagrams showing the configuration around the blower nozzle 104 in the recording apparatus 1 according to the first embodiment of the present invention. Fig. 3(a) is a schematic cross-sectional view showing an enlarged view of the periphery of the blower nozzle 104. Fig. 3(b) is a schematic top view of the periphery of the blower nozzle 104 as viewed from a direction perpendicular to the transport direction (Y direction) of the recording medium 2. Fig. 3(c) is a schematic cross-sectional view of the position indicated by the dashed line D in Fig. 3(b) as viewed in the opposite direction to the transport direction (Y direction) of the recording medium 2.

[0025] 3A, the recording apparatus 1 of this embodiment includes an air blowing guide plate 105 as an air blowing guide member on the air blowing nozzle 104. In this embodiment, the air blowing nozzle 104 is disposed above the pinch roller holder 7, and the air blowing guide plate 105 is a plate-shaped member that separates a space facing the air blowing port 104c of the air blowing nozzle 104 from the pinch roller holder 7 into upper and lower spaces. The air blowing guide plate 105 guides the air flowing out of the air blowing port 104c of the air blowing nozzle 104 toward a supported region 2a supported by the platen 11 on the recording medium 2 while restricting the air flowing out of the air blowing port 104c from flowing toward the side (downward) where the pinch roller holder 7 is disposed.

[0026] The air blowing guide plate 105 is provided above the pinch roller holder 7 and downstream of the air blowing nozzle 104 in the air passage formed by the air blowing unit 100. More specifically, the air blowing guide plate 105 is fixed to a portion of the opening edge of the air blowing port 104c of the air blowing nozzle 104 adjacent to the pinch roller holder 7 so as to be continuous with the air blowing port 104c and extend from the air blowing port 104c toward the supported area 2a.

[0027] As shown in FIG. 3(b) and FIG. 3(c), the airflow guide plate 105 is installed so as to cover the holes (through holes) 7a in the pinch roller holder 7 and the gaps 7b between the pinch roller holders 7. The upper surface of the airflow guide plate 105, which is the surface on the space side facing the airflow port 104c, is a smooth flat surface. In addition to the through holes 7a, each pinch roller holder 7 may be provided with, for example, a hollowed-out recess shape, and the surface (upper surface) of the pinch roller holder 7 facing the space side facing the airflow port 104c may not be composed of only a flat surface but may include various uneven shapes. If such uneven shapes are exposed to the flow path of the air flowing from the airflow port 104c, the flow of the air may be disturbed, and there is a concern that the air may hit the supported area 2a of the recording medium 2 unevenly. The airflow guide plate 105 separates the pinch roller holder 7 from the flow path, thereby preventing the airflow generated by the airflow fan 101 from being disturbed by the shape of the pinch roller holder 7, and enabling the airflow to be uniformly directed at the ink ejected onto the recording medium 2 on the platen 11.

[0028] The airflow guide plate 105 is divided into a plurality of parts in the width direction of the recording medium 2 along the main scanning direction. 3(c), each divided air blow guide plate 105 is disposed so that at least a portion of the divided air blow guide plate 105 overlaps with an adjacent air blow guide plate 105 in the width direction (X direction) of the recording medium 2. A collection of a plurality of air blow guide plates 105 aligned in the width direction of the recording medium 2 is configured to form a shape like a single plate that is long in the same direction.

[0029] That is, the air blowing guide plate 105 has a first connecting portion 105a extending in the width direction of the recording medium 2 from the space side (upper surface side) facing the air blowing port 104c at the end surface in the width direction at a connecting portion with the air blowing guide plate 105 adjacent to one side in the width direction of the recording medium 2. Also, the air blowing guide plate 105 has a second connecting portion 105b extending in the width direction of the recording medium 2 from the side (lower surface side) where the pinch roller holder 7 is arranged at the end surface in the width direction at a connecting portion with the air blowing guide plate 105 adjacent to the other side in the width direction of the recording medium 2. Two adjacent air blowing guide plates 105 are connected so that the first connecting portion 105a of one air blowing guide plate 105 and the second connecting portion 105b of the other air blowing guide plate 105 overlap each other when viewed in a direction (Z direction) intersecting with each of the conveying direction and the width direction of the recording medium 2. That is, the two adjacent air blowing guide plates 105 are connected so as to overlap in the width direction of the recording medium 2.

[0030] In this way, the multiple air blowing guide plates 105 are connected so that adjacent air blowing guide plates 105 have overlapping portions, thereby eliminating gaps between adjacent air blowing guide plates 105. This makes it possible to effectively prevent turbulence in the air blowing, and allows the air to be blown evenly onto the printed surface (recorded surface) of the recording medium 2 that has been printed on the platen 11.

[0031] In this embodiment, the division intervals of the multiple air blowing guide plates 105 are configured to substantially correspond to the intervals at which the air blowing ports 104c of the multiple air blowing nozzles 104 are arranged, but they may be divided in a manner that does not correspond to the intervals. Also, the air blowing guide plate 105 may be configured as a single plate that is not divided in the main scanning direction.

[0032] The airflow guide member is configured such that at least the surface (guide surface) exposed to the flow path of the air flowing out of the airflow port 104c of the airflow nozzle 104 is a smooth flat surface. In other words, components other than the guide surface that guides the airflow are not limited to a specific configuration, and for example, the surface facing the pinch roller holder 7 may be provided with an uneven shape (for example, an uneven shape corresponding to the unevenness of the pinch roller holder 7). Therefore, the form of the airflow guide member is not limited to a plate-like member such as the airflow guide plate 105 of this embodiment.

[0033] The printing apparatus according to this embodiment is a printing apparatus equipped with a so-called serial type print head that prints while scanning the print medium, however, the present invention can also be applied to a printing apparatus equipped with a so-called line type print head that has a plurality of ejection ports with a length corresponding to the width of the print medium.

[0034] <Second embodiment> In the first embodiment, a configuration in which the air blow guide plate 105 is fixed integrally to the air blow nozzle 104 has been described. In the second embodiment, a configuration in which the air blow guide plate 105 is fixed integrally to the pinch roller holder 7 will be described. Here, the second embodiment will be mainly described in terms of differences from the first embodiment, and the configurations in the second embodiment that are common to the first embodiment will be given the same reference numerals and will not be described. The configurations of the second embodiment that are not specifically described here are similar to those of the first embodiment.

[0035] The configuration around the blower nozzle 104 of the recording apparatus according to the second embodiment of the present invention will be described with reference to Figures 4(a) and 4(b). Figure 4(a) is a schematic cross-sectional view showing the configuration around the blower nozzle 104 in the recording apparatus according to this embodiment, showing the state when blowing air. Figure 4(b) is a schematic cross-sectional view showing the configuration around the blower nozzle 104 in the recording apparatus according to this embodiment. 5 shows how the recording medium 2 is set.

[0036] As shown in Fig. 4(a), in the recording apparatus of this embodiment, the air blow guide plate 105 is fixed to the upper surface of the pinch roller holder 7, i.e., to the surface of the pinch roller holder 7 facing the space facing the air blowing port 104c of the air blowing nozzle 104. Therefore, when the pinch roller holder 7 swings, the air blow guide plate 105 can move integrally with the pinch roller holder 7, as shown in Fig. 4(b). The pinch roller holder 7 may be operated to provide a gap between the transport roller 5 and the pinch roller 6, for example, when the recording medium 2 is set on the platen 11.

[0037] By providing the air blowing guide plate 105 on the pinch roller holder 7, the height of the air blowing guide plate 105 can be made closer to the platen 11. Therefore, the air blowing direction C from the air blowing nozzle 104 can be directed toward the supported area 2a of the recording medium 2 that is supported on the platen 11. Therefore, the drying efficiency of the ink ejected onto the recording medium 2 can be improved.

[0038] The air blowing guide plate 105 can be disposed so that at least a portion of the air blowing nozzle 104 having the air blowing port 104c overlaps with the tip of the air blowing nozzle 104 in the transport direction. That is, when viewed in a direction perpendicular to the air blowing path (approximately the Z direction), the tip side portion of the air blowing nozzle 104 and the air blowing guide plate 105 may be configured to have a portion where they overlap (overlapping portion). This can reduce the gap between the air blowing nozzle 104 and the air blowing guide plate 105, and further reduce turbulence in the air blow, allowing the air blow to be applied uniformly to the recording medium 2 printed on the platen 11.

[0039] <Third embodiment> In the third embodiment of the present invention, yet another configuration example will be described regarding the configuration in which the air blower guide plate 105 is fixed integrally to the pinch roller holder 7. Here, the differences between the third embodiment and the first and second embodiments will be mainly described, and the configurations in the third embodiment that are common to the first and second embodiments will be given the same reference numerals and will not be described. The configurations of the third embodiment that are not specifically described here are similar to those of the first and second embodiments.

[0040] With reference to Figs. 5(a) to 5(c), the configuration around the air blowing nozzle 104 of the recording apparatus according to the third embodiment of the present invention will be described. Fig. 5(a) is a schematic cross-sectional view showing the configuration around the air blowing nozzle 104 in the recording apparatus according to this embodiment, showing the state when air is being blown. Fig. 5(b) is a schematic cross-sectional view showing the configuration around the air blowing nozzle 104 in the recording apparatus according to this embodiment, showing the state when the recording medium 2 is set. Fig. 5(c) is a schematic cross-sectional view showing the configuration around the air blowing nozzle 104 in the recording apparatus according to this embodiment, showing the state in which the air blowing guide plate 105 is biased by a biasing means.

[0041] The blower unit 100 is composed of a blower fan 101 as an air source, and a blower duct 103 and a blower nozzle 104 as air passage members that form an air passage (see FIG. 2).

[0042] As shown in FIG. 5(a), in this embodiment, the blower nozzle 104 connected to the downstream side of the air passage relative to the air duct 103 is composed of an air blower nozzle fixed part 104a as a fixed air passage member and an air blower nozzle movable part 104b as a movable air passage member. The air blower nozzle fixed part 104a is connected to the downstream side of the air passage relative to the air blower duct 103. The air blower nozzle movable part 104b is connected to the downstream side of the air passage relative to the air blower nozzle fixed part 104a, forms an air passage integrally with the air blower nozzle fixed part 104a, and has an air outlet 104c downstream of the air passage. The air blower nozzle movable part 104b is also connected to the downstream end of the air passage of the air blower nozzle fixed part 104a via a rotating shaft 104d aligned in the main scanning direction, and rotates in the main scanning direction relative to the air blower nozzle fixed part 104a. The support member is configured to be swingable about a rotation axis along the direction of the support member.

[0043] The rear end side of the airflow guide plate 105, which is on the upstream side of the airflow path, is fixed to the underside of the airflow nozzle movable part 104b (the surface facing the pinch roller holder 7). The front end side of the airflow guide plate 105, which is on the downstream side of the airflow path, extends toward the supported area 2a of the recording medium so as to be connected to the airflow port 104c of the airflow nozzle movable part 104b. The airflow guide plate 105 is fixed to the airflow nozzle movable part 104b so that at least a part of its underside can come into contact with the pinch roller holder 7.

[0044] 5(b), when the pinch roller holder 7 swings, the air blowing nozzle movable part 104b and the air blowing guide plate 105 can move (swing in response to) the swinging of the pinch roller holder 7 due to contact between the air blowing guide plate 105 and the pinch roller holder 7. The pinch roller holder 7 may be operated to provide a gap between the transport roller 5 and the pinch roller 6, for example, when the recording medium 2 is set on the platen 11.

[0045] By providing the air blowing guide plate 105 on the pinch roller holder 7, the height of the air blowing guide plate 105 can be made closer to the platen 11. Therefore, the air blowing direction C from the air blowing nozzle movable part 104b can be directed toward the supported area 2a of the recording medium 2 that is supported on the platen 11. Therefore, the drying efficiency of the ink ejected onto the recording medium 2 can be improved.

[0046] As shown in FIG. 5(c), the air blowing nozzle movable part 104b and the air blowing guide plate 105 may be configured to follow the pinch roller holder 7 by a torsion coil spring 106 as a biasing means. That is, when the air blowing guide plate 105 is in contact (abutment) with the pinch roller holder 7, the torsion coil spring 106 biases the air blowing guide plate 105 toward the pinch roller holder 7 so that the contact state (abutment state) is maintained. The biasing force F generated by the torsion coil spring 106 enables the air blowing guide plate 105 to more reliably follow the operation of the pinch roller holder 7. For example, depending on the conveyance state of the recording medium 2, the pinch roller 6 may be momentarily lifted, causing the pinch roller holder 7 to suddenly rise, and the air blowing guide plate 105 may be jumped up by the impact. In such a case, there is a concern that the air blowing guide plate 105 may be lifted away from the pinch roller holder 7 and collide with, for example, the carriage 4. According to this embodiment, the force of the torsion coil spring 106 prevents the air guide plate 105 from being lifted up away from the pinch roller holder 7, thereby reducing the risk of the air guide plate 105 colliding with the carriage 4.

[0047] In the example shown in FIG. 5(c), a torsion coil spring 106 is illustrated as the biasing means, but the specific configuration of the biasing means is not limited to this, and may be, for example, a compression spring or a rubber member.
