Description

The present invention particularly relates to a sublimation transfer type inkjet recording apparatus and an inkjet recording method.

Conventionally, a sublimation transfer type inkjet recording method has been proposed in Patent Document 1 and the like.

The sublimation transfer inkjet recording method attaches sublimation ink to an intermediate transfer medium, evaporates the moisture in the ink by heating, concentrates it, and then presses the intermediate transfer medium against the recording medium for transfer. This prevents ink from bleeding or penetrating into the recording medium.

In particular, when the recording medium is cloth, applying ink directly with an inkjet head will cause smearing on the cloth, so a sublimation transfer type inkjet recording device is superior to such a direct type. I can say that there is.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram of an inkjet recording apparatus according to an embodiment of the present invention.

The inkjet recording apparatus 100 includes a printing section 110 having an inkjet head 111, an intermediate transfer belt 120 as a carrier, a heating roller 131, and a pressure belt 141.

The printing unit 110 includes an inkjet head 111 and a drive unit (not shown) that drives the inkjet head 111. The inkjet head 111 discharges sublimable ink to form a printed image on the intermediate transfer belt 120. In the case of the present embodiment, the printing unit 110 is of a shuttle type in which the inkjet head 111 is driven for main scanning in a direction perpendicular to the conveyance direction of the intermediate transfer belt 120 (direction of arrow a in the figure). However, the printing unit 110 is not limited to the shuttle type, but may also be a line type.

The transfer surface side of the intermediate transfer belt 120 (that is, the surface facing the inkjet head 111) is subjected to a blasting process by, for example, polishing. This makes it difficult for the sublimable ink to spread on the belt surface. As a result, image quality deterioration on the intermediate transfer belt 120 is suppressed.

The intermediate transfer belt 120 is an endless belt, and spans between a heating roller 131 and a driving roller 161. The intermediate transfer belt 120 is conveyed in the direction of arrow a in the figure by rotationally driving the drive roller 161.

The inkjet recording apparatus 100 includes a recording medium transport section 150. The recording medium transport unit 150 includes a feed roller 151 , a take-up roller 152 , and a press roller 153 , and the take-up roller 152 takes up the recording medium 1 that is wound around the feed roller 151 .

In the case of this embodiment, the recording medium 1 is cloth. More specifically, the recording medium 1 is a polyester fiber.

The recording medium 1 is introduced between the intermediate transfer belt 120 wrapped around a predetermined area of the heating roller 131 and the pressure belt 141 . Thereby, the recording medium 1 is conveyed in the same direction as the conveyance direction of the intermediate transfer belt 120 while being pressurized and heated in the direction of the intermediate transfer belt 120 .

In the inkjet recording apparatus 100 of this embodiment, the heating roller 131 and the intermediate transfer belt are connected from the position where the intermediate transfer belt 120 starts wrapping around the heating roller 131 to the position where the recording medium 1 starts contacting the intermediate transfer belt 120. The area 120 functions as a drying section 130.

In addition, in the inkjet recording apparatus 100 of the present embodiment, the heating roller 131, the intermediate The areas of the transfer belt 120 and the pressure belt 141 function as a transfer section 140.

The drying section 130 dries the sublimable ink adhered to the surface of the intermediate transfer belt 120 using heat from the heating roller 131 before sublimation transfer onto the recording medium 1 . This makes it possible to suppress ink bleeding and the like during sublimation transfer.

The winding length of the intermediate transfer belt 120 around the heating roller 131 in the drying section 130, that is, the drying distance is preferably 1/4 or more and 1/2 or less of the circumferential length of the heating roller 131. Here, by making it 1/4 or more of the peripheral length, the distance for heating and drying can be increased. This also contributes to miniaturization of the heating roller 131. Further, by setting the circumference to 1/2 or less, the transfer unit 140 sharing the heating roller 131 is sufficient to sublimate and transfer the sublimable ink attached to the surface of the intermediate transfer belt 120 onto the recording medium 1. A safe distance can be maintained.

In the transfer unit 140, the winding length of the pressure belt 141 and the intermediate transfer belt 120 around the heating roller 131 is preferably 1/4 or more and 1/2 or less of the circumferential length of the heating roller 131. Here, by setting the winding length to 1/4 or more of the circumferential length, it is possible to increase the distance over which the sublimable ink attached to the surface of the intermediate transfer belt 120 is sublimated and transferred by heating and pressurizing it. . This also contributes to miniaturization of the heating roller 131. Further, by setting the circumferential length to 1/2 or less, a sufficient distance can be secured for the drying section 130 that shares the heating roller 131 to dry the sublimable ink.

Incidentally, in the example of FIG. 1, the pressure belt 141 of the transfer section 140 is suspended between four rollers 141a to 141d. The two rollers 141a and 141b are provided facing the heating roller 131. The winding length of the pressure belt 141 around the heating roller 131 is determined by the arrangement of the two rollers 141a and 141b. It is preferable that one of the rollers 141a and 141b is a tension roller. Thereby, by controlling the tension of the tension roller, it becomes possible to change the pressing force at the transfer section 140.

The heating roller 131 has a heating source inside, and this heating source is controlled so that the surface temperature of the heating roller 131 is in the range of 150°C to 230°C.

The inkjet recording apparatus 100 has a workbench 154. The workbench 154 is arranged at a position immediately before the recording medium 1 is introduced into the transfer section 140. Thereby, for example, an operator can use the workbench 154 to perform a cutting operation of cutting the recording medium 1, which is a cloth, into a desired size.

The inkjet recording apparatus 100 includes a belt cleaning section 170 downstream of the transfer section 140 and upstream of the printing section 110 with respect to the conveyance direction of the intermediate transfer belt 120 . The belt cleaning section 170 has a cleaning blade 171, and the cleaning blade 171 presses the intermediate transfer belt 120 in the direction of the drive roller 161 to remove sublimable ink remaining on the surface of the intermediate transfer belt 120.

In the above configuration, first, sublimable ink is ejected from the inkjet head 111 and adheres to the recording medium 1, thereby forming a printed image on the intermediate transfer belt 120.

Next, the sublimable ink deposited on the intermediate transfer belt 120 is dried in the drying section 130 by the heat of the heating roller 131.

Next, the dried intermediate transfer belt 120 and the recording medium 1 are conveyed to the transfer section 140. Specifically, the intermediate transfer belt 120 and the recording medium 1 after drying are conveyed so as to pass between the heating roller 131 and the pressure belt 141. Thereby, in the transfer section 140, the intermediate transfer belt 120 and the recording medium 1 are heated and pressurized, so that the sublimable ink on the intermediate transfer belt 120 is sublimated and transferred to the recording medium 1.

As described above, according to the present embodiment, the inkjet recording apparatus 100 includes the printing section 110 that discharges sublimable ink from the inkjet head 111 to form a printed image on the intermediate transfer belt 120, and the printing section 110 that forms a printed image on the intermediate transfer belt 120. By having a drying section 130 that dries the sublimable ink adhering to the intermediate transfer belt 120 and a transfer section 140 that transfers the sublimable ink after drying on the intermediate transfer belt 120 to the recording medium 1, it has a compact configuration. First, it is possible to realize an inkjet recording apparatus that can perform high-quality sublimation transfer. In other words, according to the configuration of the present embodiment, compared to the case where the drying section and the transfer section are implemented as separate devices, the intermediate transfer belt 120 is interposed to form, dry, and print images. Since sublimation transfer can be performed continuously, it becomes possible to integrate the device into one unit, making it possible to compactly achieve everything from inkjet printing to smear-free sublimation transfer with one device. Become.

Incidentally, in conventional sublimation transfer using paper as a carrier, a drying device and a transfer-fixing device are generally provided separately. Specifically, when paper coated with sublimable ink by an inkjet head is dried by a drying device, it is once taken out from the drying device and then inserted into a transfer device. Therefore, there is a drawback that the overall device configuration becomes large. In contrast, in the configuration of this embodiment, the drying section 130 and the transfer section 140 are configured as one unit, and drying and sublimation transfer can be performed with a very compact configuration. In addition, since the intermediate transfer belt 120 is used, there is an advantage that no waste is generated compared to the case where paper is used.

Further, the inkjet recording apparatus 100 of this embodiment performs drying in the drying section 130 and sublimation transfer in the transfer section 140 using the same heating roller 131. In other words, heating is shared. Thereby, the configuration for heating can be simplified. Furthermore, temperature control can be simplified by controlling the heat source that makes up the drying section 130 and the heat source that makes up the transfer section 140 by the same temperature control section.

Further, the inkjet recording apparatus 100 of the present embodiment further includes a recording medium conveying section 150 that conveys the recording medium 1 to the transfer section 140, and the recording medium conveying section 150 is connected to the intermediate transfer belt 120 on which the printed image is formed. The recording medium 1 is fed into the transfer section 140 in synchronization with the timing at which the recording medium 1 reaches the transfer section 140. Thereby, the printed image on the intermediate transfer belt 120 can be sublimated and transferred to a predetermined position on the recording medium 1.

The embodiments described above are merely examples of implementation of the present invention, and the technical scope of the present invention should not be construed as limited by these embodiments. That is, the present invention can be implemented in various forms without departing from its gist or main features.

(1) The printing section 110 may change printing conditions depending on the type of recording medium 1. For example, when the recording medium 1 is a fabric, the ejection amount of the sublimable ink may be changed depending on the thickness of the fabric. For example, the thicker the fabric, the greater the amount of sublimable ink ejected.

(2) A wrapping amount changing section may be further provided to change the amount of wrapping of the intermediate transfer belt 120 around the heating roller 131 in the transfer section 140 and/or the drying section 130 based on the conveyance speed of the intermediate transfer belt 120. For example, as the conveyance speed of the intermediate transfer belt 120 increases, the amount of wrapping of the intermediate transfer belt 120 around the heating roller 131 in the transfer section 140 and/or the drying section 130 increases. By doing so, even when the conveyance speed of the intermediate transfer belt 120 changes, uniform transfer performance and drying performance can be obtained.

In order to change the amount of wrapping of the intermediate transfer belt 120 at the transfer section 140, for example, the rollers 141a and 141b may be moved in the circumferential direction of the heating roller 131. In addition, in order to change the amount of winding of the intermediate transfer belt 120 in the drying section 130, for example, as shown in FIGS. , and move the movable roller 201 in the circumferential direction of the heating roller 131.

FIG. 2A shows an example in which a movable roller 201 is provided on the printing surface side of the intermediate transfer belt 120. In this case, if the movable roller 201 directly presses the printing surface, it will cause disturbances because the image is not yet dry, so the movable roller 201 will come into contact only with both ends of the intermediate transfer belt 120, which are non-printing (drawing) areas. ing.

FIG. 2B shows an example in which a movable roller 201 is provided on the side of the intermediate transfer belt 120 opposite to the printing side. In this case, since the movable roller 201 contacts the intermediate transfer belt 120 from the side opposite to the printing surface, the movable roller 201 may contact the intermediate transfer belt 120 over the entire width of the belt without disturbing the image. In this case, a roller is provided between the inkjet head 111 and the movable roller 201 that contacts only the ends of the non-printing (drawing) area to keep the distance between the inkjet head 111 and the intermediate transfer belt 120 constant. It's okay.

(3) A wrapping amount changing section may be further provided to change the amount of wrapping of the intermediate transfer belt 120 around the heating roller 131 in the transfer section 140 and/or the drying section 130 based on the temperature of the heating roller 131. For example, the lower the temperature of the heating roller 131, the greater the amount of wrapping of the intermediate transfer belt 120 around the heating roller 131 in the transfer section 140 and/or the drying section 130. By doing so, even when the temperature of the heating roller 131 changes, uniform transfer performance and drying performance can be obtained.

(4) A wrapping amount changing unit that changes the amount of wrapping of the intermediate transfer belt 120 around the heating roller 131 in the transfer unit 140 and/or the drying unit 130 based on the amount of sublimable ink ejected from the inkjet head 111; It may be provided. For example, as the amount of sublimable ink that is ejected increases, the amount by which the intermediate transfer belt 120 is wrapped around the heating roller 131 in the transfer section 140 and/or the drying section 130 is increased. By doing so, even when the amount of ink changes, uniform transfer performance and drying performance can be obtained.

(5) As shown in FIG. 3, a temperature detection section that detects the temperature of the intermediate transfer belt 120 is located downstream of the transfer section 140 and upstream of the printing section 110 with respect to the conveyance direction of the intermediate transfer belt 120. 202 may be further provided. By doing so, it becomes possible to accurately grasp the temperature of the intermediate transfer belt 120 after sublimation transfer, and temperature control suitable for drying and transfer can be performed. That is, the temperature of the intermediate transfer belt 120 fluctuates greatly due to heat transfer due to sublimation transfer of the sublimable ink to the recording medium 1 in the transfer section 140. Therefore, if the sublimation transfer continues, the surface temperature of the intermediate transfer belt 120 becomes non-uniform, and if the temperature is controlled only by temperature detection by the heating roller 131, an undesirable temperature that deviates from the actual surface temperature of the intermediate transfer belt 120 is generated. It may become a control. By providing the temperature detection unit 202 and controlling the temperature of the heating roller 131 based on the detected temperature, inconveniences caused by heat transfer due to sublimation transfer can be avoided.

(6) In addition to the embodiments described above, printing by the printing unit 110 may be started after detecting that the surface temperature of the entire intermediate transfer belt 120 has reached a predetermined temperature. By doing this, drying of the sublimable ink and sublimation transfer are performed after the temperatures of the heating roller 131, pressure belt 141, and intermediate transfer belt 120 are stabilized at a uniform temperature. It becomes possible to obtain drying performance and sublimation transfer performance.

(7) Alternatively, the intermediate transfer belt 120 may be rotated idly without printing until the surface temperature of the entire intermediate transfer belt 120 reaches a predetermined temperature. As a result, the intermediate transfer belt 120 is rotated idly until the temperatures of the transfer section 140 and the intermediate transfer belt 120 become uniform, so that the temperature increase of the transfer section 140 is promoted and the warm-up time can be shortened.

(8) Furthermore, the inkjet head 111 may be retracted from the intermediate transfer belt 120 until the heating roller 131 or the intermediate transfer belt 120 reaches a predetermined temperature (that is, during warm-up). As a result, the inkjet head 111 is not heated by the heat from the intermediate transfer belt 120 during warm-up, so thickening of the ink can be avoided.

(9) In addition to the embodiments described above, any one or more of the rollers 141a to 141d on which the pressure belt 141 is suspended may have a heating function to heat the pressure belt 141. In this way, the intermediate transfer belt 120 and the recording medium 1 can be heated by both the heating roller 131 and the pressure belt 141, and the performance of sublimation transfer can be improved. This is particularly effective when a thick cloth is used as the recording medium 1.

(10) The cleaning liquid used in the belt cleaning section 170 may be cooled, and the surface of the intermediate transfer belt 120 may be cooled by cleaning. By doing so, it is possible to suppress an increase in the temperature of the inkjet head 111 due to heat from the intermediate transfer belt 120, and it is possible to avoid thickening of the ink. Of course, the method for cooling the intermediate transfer belt 120 is not limited to this, and the intermediate transfer belt 120 may be cooled by, for example, blowing air from a blower.

(11) In addition to the above-described embodiment, as shown in FIG. A material application section 203 may be provided. The pretreatment application section 203 applies an image receiving liquid (pretreatment material) to the surface of the intermediate transfer belt 120 (the surface on which a printed image is formed). This makes it difficult for the sublimable ink to spread on the belt surface, and deterioration of the image quality of the printed image on the intermediate transfer belt 120 is suppressed. Furthermore, if a flexo (letterpress) printing method is adopted in the pretreatment material application section 203, the amount of pretreatment material to be applied can be reduced, and the pretreatment material can be applied accurately to the position where a printed image is to be formed.

(12) In addition to the embodiments described above, the printing unit 110 includes a position detection unit (encoder) that detects the conveyance position of the intermediate transfer belt 120 and a storage unit that stores information from the position detection unit. The printed image position is stored as position information from the position detection unit from the timing when printing starts, and the recording medium transport unit 150 determines the timing to start transporting the recording medium 1 to the transfer unit 140 based on the position information from the position detection unit. It may be decided. In this way, for example, when the recording medium 1 is cut fabric, the print position on the cut fabric can be aligned.

(13) In the above-described embodiment, a case was described in which cloth was used as the recording medium 1, but the recording medium 1 is not limited to this, and may be paper, for example. However, in the embodiment described above, the pressure belt 141 is wound around the heating roller 131 within a range of 1/4 or more and 1/2 or less of the circumferential length of the heating roller 131, and the heating roller 131 and the pressure belt 141 are Since the recording medium 1 is heated and pressurized between the two, when the recording medium 1 is cloth, it is possible to obtain the effect that the wrinkles of the cloth can be smoothed out and the transfer can be performed reliably.

(14) In the above-described embodiment, the intermediate transfer belt 120 is used as a carrier for sublimable ink, but the carrier may be paper, for example. However, the use of the intermediate transfer belt 120 has the advantage that it can be used repeatedly compared to the case of using paper, so there is no waste, and running costs can be reduced.

INDUSTRIAL APPLICATION This invention is widely applicable as a technique of transferring the image by sublimation ink to recording media, such as a cloth.
