Japanese Patent No. 4429923

  The above prior art employs a heat conduction method by heating a supporting member that supports the recording medium, and therefore, the rise in temperature is slow or the temperature distribution becomes non-uniform due to poor contact with the recording medium. There is. Further, in the heat conduction method, heating is performed from the back side opposite to the recording surface of the recording medium, so that the amount of heat to be supplied must be varied depending on the thickness of the recording medium.

  Therefore, it is conceivable to adopt a method using an infrared heater that heats the recording surface uniformly and quickly by directly irradiating the recording surface with infrared rays instead of from the back side of the recording medium. However, this method rapidly heats the recording surface side, which may cause problems such as undulation (so-called cockling) of the recording medium due to the influence of thermal expansion.

  In the preheating device that heats the recording medium in a state where it is not sufficiently warmed, there is a problem that the above-described adverse effect is likely to occur and it is difficult to adopt a method using an infrared heater.

The recording medium is preheated on the second support surface. As a result, the infrared radiation energy scattered as diffused light can be used, and power saving can be achieved by not installing an infrared heater separately for preheating, and the number of parts can be reduced and space can be saved by combining the combined functions of drying and preheating. .

In the present invention, the infrared heater employs a configuration that irradiates infrared rays obliquely toward the first support surface from the downstream side of the recording head in the transport direction.

  The recording unit 3 includes an ink jet head (recording head) 31 that ejects ink onto the medium M to be transported, and a carriage 32 that is mounted with the ink jet head 31 and can reciprocate in the width direction (vertical direction in FIG. 1). And have. The inkjet head 31 includes a plurality of nozzles, and is configured to eject ink that is selected in relation to the medium M and that requires permeation drying or evaporation drying.

The heating unit 4 is configured to quickly dry and fix the ink on the medium M by heating the medium M, thereby preventing bleeding and blurring and improving the image quality.
The heating unit 4 includes a preheater unit 41 that preheats the medium M on the upstream side in the transport direction from the position where the recording unit 3 is provided, a platen heater unit 42 that heats the medium M at a position facing the recording unit 3, And an after heater 43 that heats the medium M on the downstream side in the transport direction from the position where the recording unit 3 is provided.

  In the present embodiment, the heating temperature of the heater 41a in the pre-heater unit 41 is set to 40 ° C. In the present embodiment, the heating temperature of the heater 42a in the platen heater section 42 is set to 40 ° C. (target temperature), similarly to the heater 41a. Moreover, in this embodiment, the heating temperature of the heater 43a in the after-heater part 43 is set to 50 degreeC higher than the heaters 41a and 42a.

The pre-heater unit 41 is configured to promptly dry the ink M after landing by gradually raising the temperature of the medium M from the normal temperature toward the target temperature (the temperature in the platen heater unit 42).
The platen heater 42 is configured to cause the medium M to receive ink landing while maintaining the target temperature, and to promptly dry the ink from landing.

  Further, the after-heater unit 43 raises the temperature of the medium M to a temperature higher than the target temperature, quickly dries the ink that has landed on the medium M, which has not yet been dried, and at least before winding it with the roll 22. In this configuration, the landed ink is completely dried and fixed on the medium M.

Then, the characteristic structure in the heating part 4 of this embodiment is demonstrated.
FIG. 2 is a configuration diagram showing the heating unit 4 in the embodiment of the present invention. In FIG. 2, the part concerning the pre-heater part 41 and the platen heater part 42 among the heating parts 4 is shown typically.

  As illustrated in FIG. 2, the platen heater unit 42 includes a first support member 51 (platen) including a first support surface 50 that supports the medium M. The first support member 51 is a flat plate made of metal, and is provided so as to extend in the width direction (perpendicular to the paper surface in FIG. 2) perpendicular to the conveyance direction of the medium M. The first support member 51 has a width larger than the width of the medium M in order to support the medium M in the width direction.

  A heater 42 a is wired on the surface 52 opposite to the first support surface 50 of the first support member 51. The heater 42a is a tube heater and is affixed to the opposite surface 52 via an aluminum tape (not shown). Therefore, the heater 42a heats and heats the first support member 51 from the opposite surface 52 by heat conduction, and indirectly heats the medium M supported on the first support surface 50 from the back side. It has a configuration.

  An infrared heater 53 is provided at a position facing the first support surface 50 of the first support member 51. The infrared heater 53 is provided at a predetermined distance from the first support surface 50 and extends in the width direction of the first support member 51. Accordingly, the infrared heater 53 directly irradiates the first support surface 50 with infrared energy to radiately heat the first support member 51, and the medium M is supported on the first support surface 50. In this case, the recording surface side of the medium M is directly radiantly heated.

  The infrared heater 53 is configured to irradiate an electromagnetic wave having a wavelength in which the main part of the peak of the radiation spectrum includes a region of 2 μm to 4 μm. As a result, the infrared heater 53 can vibrate the water molecules contained in the ink without promptly increasing the temperature of the surrounding constituent members that do not contain water molecules, and promptly promote the drying by the frictional heat. Therefore, most of the infrared energy can be absorbed by the ink, and the ink landed on the recording surface can be heated intensively.

  The infrared heater 53 includes a reflecting plate 54 and is configured to irradiate infrared rays obliquely toward the first support surface 50 from the downstream side in the transport direction with respect to the inkjet head 31 (indicated by a dotted line in FIG. 2). Show). The infrared irradiation range by the infrared heater 53 is set on the first support surface 50, includes a print area by the inkjet head 31, and is configured to immediately heat ink landed on the recording surface. The reflection plate 54 of the present embodiment has a substantially arc shape in cross section and is disposed on the back side opposite to the infrared irradiation direction. The reflection plate 54 is made of a metal material such as an Al material or a SUS material, and is formed by mirror-finishing the inner surface thereof.

  The pre-heater unit 41 includes a second support member 61 including a second support surface 60 that supports the medium M on the upstream side in the transport direction from the first support member 51. The second support member 61 is a metal plate material formed with a bend, and has a shape in which the second support surface 60 side has a substantially curved convex shape as a whole. The second support member 61 is also provided with the same width as the first support member 51 and extending in the width direction. The first support surface 50 and the second support surface 60 cooperate with each other to form a transport path for the medium M.

  A heater 41 a is wired on the surface 62 opposite to the second support surface 60 of the second support member 61. The heater 41a is a tube heater and is affixed to the opposite surface 62 via an aluminum tape (not shown). Accordingly, the heater 41a heats and heats the second support member 61 from the opposite surface 62 by heat conduction, and indirectly heats the media M supported on the second support surface 60 from the back side. It has a configuration.

  A reflective plate 63 is provided at a position facing the second support surface 60 of the second support member 61. The reflecting plate 63 is provided with a predetermined distance from the second support surface 60 and extending across the width direction of the second support member 61. The reflecting plate 54 of this embodiment has a substantially arc shape in cross section. The reflection plate 63 is made of a metal material such as an Al material or a SUS material, and is formed by mirror-finishing the inner surface thereof.

  The reflection plate 63 is configured to reflect at least a part of the infrared rays that have deviated from the first support surface 50 toward the second support surface 60. That is, the reflecting plate 63 is disposed in a shape and an orientation in which the reflecting surface faces both the second support surface 60 and the infrared heater 53. Therefore, when the medium M is supported on the second support surface 60, the reflection plate 63 reflects the diffused light of the infrared heater 53 that has come off from the first support surface 50, and the recording surface of the medium M The energy can contribute to preheating.

  The reflection plate 63 is provided on the upstream side in the transport direction from the transport roller 23 that transports the medium M between the first support member 51 and the second support member 61. The conveyance roller 23 includes a driving roller 23a and a driven roller 23b. The drive roller 23a is connected to a drive source such as a motor (not shown) and is configured to rotate. On the other hand, the driven roller 23b is configured to rotate following the rotational driving of the driving roller 23a.

  The driven roller 23 b is supported by the holder 70. The holder 70 is rotatable around a rotation shaft 70a extending in the width direction, and is biased downward (counterclockwise in FIG. 2) by a spring member (not shown). The holder 70 is disposed on a straight path (indicated by a symbol L) connecting the infrared heater 53 and the reflection plate 63. The holder 70 has at least one (both in the present embodiment) of an opening 71 for opening at least a part of the straight path L and a notch 72 (see FIG. 3 described later).

FIG. 3 is a perspective view showing the holder 70 in the embodiment of the present invention.
A plurality of driven rollers 23 b of this embodiment are provided, and these driven rollers 23 b are supported by a plurality of holders 70. The holder 70 is provided side by side in the width direction orthogonal to the transport direction. An opening 71 is formed at the center of the holder 70, and notches 72 are formed on both sides of the opening 71 in the width direction. The notch 72 is configured to form a large gap in cooperation with the notch 72 of the holder 70 adjacent in the width direction.

  The opening 71 and the notch 72 are formed at positions corresponding to the straight path L connecting the infrared heater 53 and the reflection plate 63. The opening 71 of the present embodiment is rectangular, but may be a square, another polygon, a circle, an ellipse, or the like as long as at least a part of the straight path L is opened. The same applies to the shape of the notch 72. Also, the number may be plural instead of singular, and for example, at least a part of the holder 70 may be formed of a net-like body such as punching metal or expanded metal.

Next, the operation and action during printing in the heating unit 4 having the above configuration will be described.
When the medium M is conveyed to the printing area on the first support surface 50, printing is started by the inkjet head 31. In the platen heater section 42, the first support member 51 is at a predetermined temperature (40 ° C. in the present embodiment) by the heater 42a. The inkjet head 31 is mounted on the carriage 32 and performs printing while reciprocating in the width direction.

  As shown in FIG. 2, the infrared heater 53 irradiates infrared rays toward a predetermined infrared irradiation range set on the first support surface 50. Since the infrared irradiation range includes a print area by the ink jet head 31, when the carriage 32 is retracted from the area of the recording surface on which the ink has landed, the main portion of the peak of the radiation spectrum is 2 μm to 4 μm. It is directly radiantly heated at a wavelength including this region. Then, the water molecules contained in the landed ink vibrate, and the frictional heat promotes evaporation and drying, so that the ink is fixed without causing bleeding or the like to the media M.

  By the way, although the infrared rays irradiated from the infrared heater 53 define the irradiation range, irradiation direction, and the like by the reflecting plate 54, there are those that deviate from the first support surface 50 due to radiation diffusion. The reflection plate 63 reflects at least a part of the infrared rays deviating from the first support surface 50 toward the second support surface 60 disposed on the upstream side in the transport direction, and supports the second support surface 60. The medium M is made to reach the recording surface of the medium M, and the medium M is preheated. Thereby, the infrared radiation energy scattered as diffuse scattered light by the infrared heater 53, that is, waste heat, can be used for preheating.

  Depending on the design of the reflector 54, it is possible to include not only the first support surface 50 but also the second support surface 60 in the infrared irradiation range, but drying by increasing the power of the infrared heater 53 and expanding the irradiation range. In this embodiment, the infrared radiation energy scattered as a diffused light is used because an adverse effect on the capability can be considered. As a result, the infrared radiation energy scattered as diffused light can be used, and power saving can be achieved by not installing an infrared heater separately for preheating, and the number of parts can be reduced and space can be saved by combining the combined functions of drying and preheating. .

  Further, in the pre-heater unit 41 that heats the medium M in a state where it is not sufficiently warmed, the recording surface side can be heated rapidly by infrared irradiation, which may cause problems such as undulation of the medium M (so-called cockling). Infrared rays that reach the recording surface are diffusely scattered light and the energy thereof is relatively small. Therefore, such an adverse effect cannot occur. Further, since the medium M in the pre-heater unit 41 is conductively heated from the back side by the heater 41a, the difference in thermal expansion between the recording surface side and the back side where the infrared rays reach is reduced. No negative effects can occur.

  Further, the infrared heater 53 is configured to irradiate infrared rays obliquely toward the first support surface 50 from the downstream side in the transport direction with respect to the ink jet head 31. Most of them diffuse toward the upstream side in the transport direction. Therefore, it becomes easier to utilize diffused light for preheating. And the infrared rays diffused upstream of the conveyance roller 23 in the conveyance direction are used for preheating. Here, the holder 70 that supports the driven roller 23 b constituting the transport roller 23 is disposed on a straight path connecting the infrared heater 53 and the reflection plate 63.

  The holder 70 of the present embodiment has both an opening 71 and a notch 72 that open at least a part of the straight path L. Therefore, the infrared rays from the infrared heater 53 that has deviated from the first support surface 50 reach the reflector 63 through the opening 71 and the notch 72 without being blocked by the holder 70, and are used as preheating. The Thus, in this embodiment, even if the holder 70 is arranged on the straight path L by providing the opening 71 and the notch 72 in the holder 70 of the transport roller 23, the infrared heater 53. It is possible to sufficiently supply the diffused infrared radiant energy to the medium M on the second support surface 60 so that the linear path L that connects the reflector 63 and the reflector 63 is not thermally blocked.

Therefore, according to the above-described embodiment, the transport unit 2 that transports the medium M, the first support member 51 that includes the first support surface 50 that supports the medium M, and the first support surface 50. An inkjet head 31 that ejects ink, an infrared heater 53 that irradiates infrared rays toward the first support surface 50, and a second support that supports the medium M upstream of the first support member 51 in the transport direction. A printer 1 having a second support member 61 having a surface 60 and a reflecting plate 63 that reflects at least a part of the infrared rays deviated from the first support surface 50 toward the second support surface 60 is employed. Thus, the printer 1 that performs recording by ejecting fluid onto the medium M on the first support surface 50 of the first support member 51 and drying and fixing by irradiating the ejected fluid with infrared rays. In this case, the diffused light of the infrared heater 53 deviated from the first support surface 50 is reflected by the reflection plate 63, and the second support member 61 of the second support member 61 on the upstream side in the transport direction from the first support member 51. It is possible to reach the second support surface 60 and preheat the medium M on the second support surface 60. As a result, the infrared radiation energy scattered as diffused light can be used, and power saving can be achieved by not installing the infrared heater 53 separately for preheating, and the number of parts can be reduced and the space can be saved by combining the combined functions of drying and preheating. Become.
Therefore, in the present embodiment, the printer 1 that can efficiently preheat the medium M with power saving is obtained.

  As mentioned above, although preferred embodiment of this invention was described referring drawings, this invention is not limited to the said embodiment. Various shapes, combinations, and the like of the constituent members shown in the above-described embodiments are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

  For example, in the above-described embodiment, the holder 70 includes the opening 71 and the cutting portion that open at least a part of the linear path L so as not to thermally block the linear path L connecting the infrared heater 53 and the reflector 63. Although described as having at least one of the notches 72, the present invention is not limited to this configuration.

For example, at least one holder 70 among the plurality of holders 70 arranged on the straight path L connecting the infrared heater 53 and the reflector 63 is, as shown in FIG. In FIG. 4, a configuration may be adopted in which the holder 70 is arranged at a distance from each other in the horizontal direction of the drawing.
According to this configuration, by thinning the holder 70 to such an extent that the conveyance of the medium M is not hindered, a gap can be formed between the holders 70 without particularly forming the opening 71 or the notch 72. . The gap prevents the linear path L connecting the infrared heater 53 and the reflection plate 63 from being thermally blocked, and the diffused infrared radiation energy can be sufficiently supplied to the medium M on the second support surface 60. Can be made.

The holder 70 may be configured to be thinned at equal intervals, for example, every other one or two. However, as shown in FIG. 4, the thinning interval is devised, and the interval between the holders 70 is increased toward both ends in the transport direction. A configuration may be adopted.
For example, when the intervals between the holders 70 are equal, the medium M on the second support surface 60 can be heated substantially uniformly in the width direction, but the end of the medium M is easier to dissipate than the center. Due to the heat dissipation characteristics, temperature distribution tends to occur. Therefore, as shown in FIG. 4, by increasing the distance between the holders 70 toward both ends in the transport direction, more infrared radiation energy can be supplied to the end of the medium M, thereby reducing the temperature distribution. Can do. That is, since the media M can be preheated substantially uniformly in the pre-heater unit 41, it is possible to make it more difficult to cause adverse effects such as undulation of the media M.

Moreover, as shown in FIG. 5, you may employ | adopt the structure of having the adjustment apparatus 80 which adjusts the space | interval with the adjacent holder 70. FIG. The adjusting device 80 includes a plate-like guide 81 extending in the width direction, and a slider 82 provided integrally with each of the plurality of holders 70. The slider 82 has a claw shape that engages with the guide 81, and is provided so as to reciprocate in the width direction along the guide 81.
According to this configuration, it is possible to easily control the preheating by adjusting the gap between the holders 70 as described above. For example, the gap between the holders 70 can be easily adjusted according to the type, shape, width, etc. of the medium M.

Further, for example, as shown in FIG. 6, the holder 70 may be formed of a transparent member that transmits infrared rays.
According to this configuration, the infrared ray is transmitted without passing through the linear path L without forming the opening 71 or the cutout portion 72 or by thinning the holder 70 so that the linear path L is not thermally blocked. Energy can be sufficiently supplied to the medium M on the second support surface 60. As this transparent member, it is preferable to employ an infrared transmitting resin such as a methacrylic resin. Moreover, transparent glass etc. may be sufficient.
Needless to say, the above-described formation of the opening 71 and the notch 72, thinning out of the holder 70, and formation from the transparent member can be applied in an appropriate combination.

  For example, in the above-described embodiment, the case where the recording apparatus is the printer 1 has been described as an example. However, the recording apparatus is not limited to the printer, and may be an apparatus such as a copying machine or a facsimile.

  Further, as the recording apparatus, a recording apparatus that ejects or discharges fluid other than ink may be employed. The present invention can be applied to various recording apparatuses including, for example, a recording head that discharges a minute amount of liquid droplets. The droplet means a state of the liquid ejected from the recording apparatus, and includes a liquid having a granular shape, a tear shape, or a thread shape. The liquid here may be any material that can be ejected by the recording apparatus. For example, it may be in a state in which the substance is in a liquid phase, such as a liquid with high or low viscosity, sol, gel water, other inorganic solvents, organic solvents, solutions, liquid resins, liquid metals (metal melts ) And a liquid as one state of a substance, as well as a material in which particles of a functional material made of a solid such as a pigment or metal particles are dissolved, dispersed or mixed in a solvent. A typical example of the liquid is ink as described in the above embodiment. Here, the ink includes general water-based inks and oil-based inks, and various liquid compositions such as gel inks and hot melt inks. The recording medium includes paper, functional paper, synthetic paper, a substrate, a metal plate, and the like in addition to plastic films such as polyvinyl chloride and pet film.
