Description

  The present invention relates to a coating material drying apparatus and a recording apparatus.

In recent years, as an image recording apparatus capable of recording an image at a high speed, simply and inexpensively compared with a printing system that requires plate making such as a gravure printing system or a flexographic printing system, an image recording apparatus using an inkjet recording system, that is, Inkjet recording apparatuses are widely used.
The ink jet recording apparatus employs a method of recording an image on a recording medium by ejecting ink from the recording head and landing on the recording medium. The image recording method is characterized in that image recording can be performed on a recording medium having poor ink absorbability, such as a resin film or metal, which is difficult to record.

These recording media are usually transported on a support plate called a platen, and ink is ejected from a recording head thereabove. The ink (coated material) applied on the recording medium is dried by a drying device in a later process and fixed on the recording medium. When the coating is dried, unevenness in drying may occur, which may adversely affect the coating properties.
Therefore, Patent Document 1 discloses that a vertical wind drying zone in which the air flow is parallel to the coating film transport direction and parallel to the coating film surface, and the air flow is perpendicular to the coating film transport direction, and Further, there is disclosed a coated product manufacturing apparatus in which a cross wind drying zone parallel to the coating surface is sequentially arranged in the transport direction of the coating film.

On the lower surface (nozzle formation surface) of the recording head 36, a large number of ink discharge nozzles are arranged in the medium width direction (X direction). The recording head 36 performs printing by ejecting ink supplied from the valve unit 37 from the ink discharge nozzle toward the continuous paper 12 on the platen 28.
Note that the recording head 36 may have a plurality of ink discharge nozzle arrays. In this case, when performing color printing of 4 colors or 6 colors, if ink is assigned to each ink discharge nozzle row for each color type, a single recording head 36 can eject a plurality of colors of ink. Become.

  In the printing chamber 22A, an area on the platen 28 is a printing area R where printing is performed on the continuous paper 12 by ink ejection from the ink discharge nozzles. The continuous paper 12 is intermittently conveyed by the supply conveyance system and the discharge conveyance system described above. Specifically, the continuous paper 12 having a length corresponding to the printing region R is loaded onto the platen 28 every time printing is performed, and is sent to the discharge conveyance system after the printing process.

  As shown in FIGS. 1 and 2, the guide shaft 35 extending into the printing chamber 22 </ b> A extends to the outside in the medium transport direction from the printing region R. Thereby, the carriage 35a can be moved to an area outside the printing area R. A first maintenance area R1 is provided on the upstream side (−Y side) in the medium conveyance direction of the printing area R, and a second maintenance area R2 is provided on the downstream side (+ Y side) in the medium conveyance direction.

A maintenance unit 60 is provided in the first maintenance region R1.

By disposing the carriage 35a in the second maintenance region R2, the nozzle forming surface of the recording head 36 can be exposed in the work space, and the operator can clean the nozzle forming surface, replace the recording head 36, and the like. It becomes possible.

  In the printer 11 having the above-described configuration, the continuous paper 12 is intermittently fed out along the conveyance direction from the roll body 120 supported by the winding shaft 18 by the supply conveyance system, and the continuous paper 12 conveyed on the platen 28. The printing operation by the recording head 36 is sequentially executed on the predetermined recording area (printing area), and a predetermined liquid is applied to the surface 12 a of the continuous paper 12.

  The continuous paper 12 coated with the coating material is intermittently conveyed to the drying device 10 by the supply conveyance system, and is sequentially dried for each recording area. More specifically, as shown in FIG. 3, hot air is supplied from the supply device 8 to the supply space 62 in the drying device 10 and flows toward the −X side. In the supply space 62, the downstream side of the hot air is throttled by the protruding wall 65, so that the air pressure rises, and the first hot air W <b> 1 enters the drying space 61 from each nozzle hole 64 toward the surface 12 a of the continuous paper 12 in the Z direction. Along the way.

On the other hand, part of the hot air supplied to the supply space 62 flows through the supply flow path 70 and is supplied from the nozzle hole 69 to the drying space 61 along the X direction as the second hot air W2.
At this time, the opening area of each nozzle hole 64 is set smaller than the opening area of the nozzle hole 69, and the supply speed of the first hot air W <b> 1 supplied from each nozzle hole 64 is supplied from the nozzle hole 69. Therefore, the first hot air W1 becomes the main flow, and the second hot air W2 becomes the sub flow.

  FIG. 5 is an enlarged view in which the continuous paper 12 supplied with the first and second hot air W1 and W2 is sectioned along the Y direction. As shown in this figure, since the distance between the plurality of nozzle holes 64 and the surface 12a of the continuous paper 12 is constant, the portion directly spraying the supplied first hot air W1 is uniformly dried. However, for example, stagnation may occur in the region facing the gap between the nozzle holes 64 adjacent in the Y direction, and the vapor pressure may increase. Here, since the second hot air is supplied from the side in an area where stagnation may occur, stagnation is eliminated and drying is performed under the same drying conditions as those where the first hot air W1 directly blows.

  In addition, in the gap region facing the gap portion between the nozzle holes 64 adjacent in the X direction, which is the flow direction of the second hot air W2, the first hot air W1 on the upstream side directly becomes the second as a barrier. Although the hot air W2 is not supplied, as shown in FIG. 4, since this region has a negative pressure compared to the region where the first hot air W1 is directly supplied, the second hot air W2 flows to the + X side. It flows in a route that is drawn in and detoured in the process. Therefore, the recording area on the surface 12a of the continuous paper 12 is uniformly dried with similar drying characteristics without causing distribution.

  The first and second hot air W1 and W2 used for drying the continuous paper 12 in the drying space 61 are exhausted through the exhaust port 71 by the operation of the exhaust device.

  As described above, in the present embodiment, hot air is supplied to one drying space 61 in both a direction substantially orthogonal to the surface 12a of the continuous paper 12 and a direction substantially parallel to the surface 12a. It is possible to uniformly dry the continuous paper 12 without causing an increase in size and without causing stagnation, thereby suppressing the occurrence of uneven drying. In the present embodiment, since the flow rate of the first hot air W1 is larger than the flow rate of the second hot air W2, the distance to the continuous paper 12 is constant in the plurality of nozzle holes 64 and drying is performed between the nozzle holes 64. The first hot air W1 that does not cause a difference in characteristics can be used as the main flow, and drying unevenness can be further suppressed. In particular, in the present embodiment, since the drying process is performed on the continuous paper 12 that is intermittently transported and stopped, it is possible to effectively dry even in a situation where stagnation is likely to occur.

  Further, in the present embodiment, since a part of the hot air supplied to the supply space 62 is used for the second hot air W2, there is no need to separately provide a second hot air supply mechanism, and the apparatus can be reduced in size and cost. Can contribute.

  As described above, the preferred embodiments according to the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the examples. Various shapes, combinations, and the like of the constituent members shown in the above-described examples 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 configuration in which the supply sources of the first hot air W1 and the second hot air W2 are shared is shown, but the present invention is not limited to this, and the configuration in which the hot air supply source is provided individually. May be.

Moreover, in the said embodiment, although it was set as the structure which has arrange | positioned the nozzle holes 64 in a grid | lattice form, as shown in FIG. 6, the nozzle holes 64 arranged with a gap in the Y direction as shown in FIG. The arrangement of the rows may be arranged in a staggered arrangement that is shifted by a half pitch between rows adjacent in the X direction.
In the configuration shown in FIG. 4, there is a difference in flow length between the second hot air W2 that passes through the position where the nozzle hole 64 does not exist and the second hot air W2 that bypasses the position where the nozzle hole 64 exists in the Y direction. However, in the configuration in which the staggered arrangement is adopted, almost all the second hot air W2 flows in a path that similarly detours, so that the continuous paper 12 can be dried with more uniform drying characteristics.

  In the above embodiment, the configuration in which the continuous paper 12 is intermittently conveyed is illustrated, but the present invention is not limited to this, and the continuous paper 12 is continuously conveyed to perform the recording process and the drying process. May be. When the continuous paper 12 is dried while being conveyed continuously, the relative velocity of the second hot air W2 with respect to the continuous paper 12 is increased by supplying the second hot air W2 from the upstream side to the downstream side in the conveyance direction. It can be suppressed that the flow of the first hot air W1 of the main flow becomes large and becomes obstructed.

  Furthermore, the base material to which the coating material is applied is not limited to continuous paper, and can be applied to a configuration in which recording processing and drying processing are performed for each sheet.

  Moreover, in the said embodiment, although the coating material drying apparatus 10 which concerns on this invention showed the structure provided in the printer 11, it is not restricted to this, What dried the thing by which the coating material was apply | coated on the base material As widely applicable.

  In the above-described embodiment, the recording apparatus that ejects a liquid such as ink has been described as an example of the recording apparatus. However, the present invention can be applied to a recording apparatus that ejects or discharges liquid other than ink. . The liquid that can be ejected by the recording apparatus includes a liquid material in which particles of a functional material are dispersed or dissolved, and a gel-like fluid.

  In the above-described embodiment, as the liquid ejected from the recording apparatus, not only ink but also a liquid corresponding to a specific application can be applied. The recording apparatus is provided with an ejecting head capable of ejecting a liquid corresponding to the specific application, ejecting the liquid corresponding to the specific application from the ejecting head, and attaching the liquid to a predetermined object. This device can be manufactured. For example, the recording apparatus disperses (dissolves) a material such as an electrode material or a color material used for manufacturing a liquid crystal display, an EL (electroluminescence) display, and a surface emitting display (FED) in a predetermined dispersion medium (solvent). The present invention can be applied to a recording apparatus that ejects a liquid (liquid material).

The recording apparatus may be a recording apparatus that ejects a bio-organic material used for biochip manufacturing, or a recording apparatus that ejects a liquid serving as a sample that is used as a precision pipette.
