When conveyance of the transfer material 5 is started from the supply roller 32 and the transfer material conveyance roller 36, the recording section 7 records a reversed image on the ink receiving layer 53 (see FIG. 2(a)) of the transfer material 5. At this time, markings are also printed. The recorded transfer material 5 is conveyed toward the peeling section 34 along the conveyance path R1. The marking on the transfer material 5 is detected by the transfer material position sensor Se6, and the conveyance of the transfer material 5 is stopped.

On the other hand, recording materials 55 are sent out one by one from the supply section 3 to the conveyance path R2 in accordance with the recording operation in the recording section 7 (see FIG. 6). The recording material 55 temporarily stops when the leading edge position is detected by the recording material position sensor Se2. The recording material 55 sent out to the conveyance path R2 is placed on the ink-receiving layer 53 of the transfer material 5 immediately before entering between the heat roller 33 and the platen roller 63 so that the leading edge of the recording material 55 matches the position of the transfer material 5. It overlaps the surface and enters between the heat roller 33 and the platen roller 63 (see FIG. 7). A laminate 155 (see FIG. 2B) consisting of the transfer material 5 and the recording material 55 is heat-pressed between the heat roller 33 and the platen roller 63.

In the laminate 155 in which the recording material 55 and the transfer material 5 are bonded under heat and pressure, the base material 50 and the unillustrated release layer constituting the transfer material 5 are peeled off at the first peeling section 34 (see FIG. 9). ). After a portion of the leading end side of the recording material 55 in the first direction D1 is peeled off, the rotation of the supply roller 32 is reversed. After that, the remaining transfer material 5 is peeled off from the leading end side of the recording material 55 in the second direction D2 by the second peeling section 44, and the base material 50 and the peeling layer are wound up by the winding roller 31 (see FIG. 10). ). By peeling the base material 50 from the laminate 155, the recorded matter 10 is formed, and the recorded matter 10 is delivered to the rotating section 20 along the conveyance path R2. By rotating the rotating section 20 by a predetermined angle, the recorded material 10 is conveyed along the conveyance path R3 and is discharged to the discharge section 4 (see FIG. 11). Further, as another configuration of the discharge section 4, it is also possible to discharge the base material 50 after it is peeled from the laminate 155 to the discharge section 4A provided at the position shown in FIG.

[Control configuration]
Next, the control configuration of the inkjet recording apparatus 1 will be explained using FIG. 4. FIG. 4 is a block diagram showing a schematic configuration of a control system that controls the operation of the inkjet recording apparatus 1. As shown in FIG. As shown in FIG. 4, the inkjet recording apparatus 1 is provided with a control section 100. The control unit 100 is provided with a CPU 101 that executes processing such as calculation, judgment, and control according to a control program stored in a program ROM 104.

The control unit 100 is provided with an interface controller 102 that controls the exchange of signals between the host device 120 and the CPU 101, an image memory 106, a RAM 108, and the like. Recording data transmitted from the host device 120 or the like is stored in the image memory 106 as bitmap data. The RAM 108 stores various data in a readable manner and is used as a work area when the CPU 101 executes processing.

The CPU 101 includes an operation panel 110 for inputting data, a recording section 7 for performing a recording operation using an inkjet recording method, a transfer material conveying section 30 for conveying the transfer material 5, and an adhesive for transferring the transfer material 5 onto a recording material 55. 2, a supply section 3 that supplies the recording material 55, a rotating section 20 that switches the conveyance path of the recording material 55, a transport section 60 that transports the recording material 55, and the like are connected. In addition, a sensor section 8 including various sensors Se1 to Se8 for detecting the positions of the transfer material 5, the recording material 55, and the rotating section 20 is also connected. The recording section 7 is provided with a plurality of recording heads 70C, 70M, 70Y, and 70K corresponding to multiple colors of ink, as well as an electric heat source provided in each nozzle of each of the recording heads 70C, 70M, 70Y, and 70K. A drive circuit and the like that drive the conversion element are provided. That is, the control section 100 controls the transfer material conveyance section 30, the recording head 70, and the adhesive section 2.

In the control system configured as described above, recording data and commands sent from the host device 120 are received by the CPU 101 via the interface controller 102. The CPU 101 receives recording data from the recording section 7 , performs recording operations, drives the transfer material conveyance section 30 , heats the heat roller 33 in the adhesive section 2 , feeds the recording material 55 by the supply section 3 , and performs printing operations by the conveyance section 60 . It performs general control such as conveyance of the recording material 55.

After analyzing the received command, the CPU 101 develops the image data of each color component of the recording data into the image memory 106 as a bitmap. Thereafter, the CPU 101 transports the transfer material 5, and sequentially reads the recording data of the corresponding color from the image memory 106 in synchronization with the transport operation, and based on the read data, prints the recording heads 70C, 70M, 70Y, The ejection energy generating element provided in each nozzle of 70K is driven. Droplets of ink are ejected from each nozzle by driving the ejection energy generating element. The ejected ink lands on the ink receiving layer 53 of the transfer material 5 at a position facing the recording head 70, forming dots. A desired image is formed on the ink receiving layer 53 of the transfer material 5 by this collection of dots.

[Control flow of inkjet recording device]
Next, the control operation of the inkjet recording apparatus 1 executed by the control unit 100 will be explained according to the flowchart shown in FIG. The CPU 101 determines whether recording data transmitted from the host device 120 has been received (step S101). If the CPU 101 determines that the recording data has been received (YES in step S101), the CPU 101 stores the recording data in the image memory 106 (step S102), and starts heating the heat roller 33 provided on the adhesive part 2 ( Step S103). The CPU 101 determines whether the temperature of the heat roller 33 has reached a predetermined temperature (step S104). If the CPU 101 determines that the temperature of the heat roller 33 has reached the predetermined temperature (YES in step S104), the CPU 101 drives the transfer material conveying section 30 to start conveying the transfer material 5 (step S105). The CPU 101 drives the supply section 3 and the conveyance section 60 at a predetermined timing according to the conveyance operation of the transfer material 5, and starts feeding and conveying the recording material 55 (step S106).

When the recording position of the transfer material 5 reaches the recording unit 7, the CPU 101 controls the drive circuit of the recording head 70 based on the recording data read from the image memory 106, and causes the recording head 70 to eject ink. As a result, an image is recorded on the ink receiving layer 53 of the transfer material 5 (step S107). The transfer material 5 and the recording material 55 on which the image has been recorded are once stopped at a predetermined position, and thereby their respective positions are aligned (step S108).

Due to this positioning, the ink receiving layer 53 of the transfer material 5 overlaps the recording material 55 and is sent between the heat roller 33 and the platen roller 63. While passing between the heat roller 33 and the platen roller 63, the recording material 55 and the transfer material 5 are heated and pressed together to form a laminate 155. This laminate 155 is transported to the first peeling unit 34, and as a first peeling process, a part of the base material 50 is peeled off by a predetermined amount from the tip of the recording material 55 on the first direction D1 side (step S109 ). That is, in the first peeling process, the entire base material 50 of the recording material 55 is not peeled off.

The laminate 155 is reversely conveyed in the second direction D2 and conveyed to the second peeling section 44, and as a second peeling process, the entire base material 50 is peeled off from the tip of the recording material 55 on the second direction D2 side. Ru. As a result, the peeling of the recording material 55 is completed, resulting in a recording material 10 (final recording material), which is stacked on the discharge section 4 (step S110).

The CPU 101 determines whether the number of recorded materials 10 manufactured as described above has reached a predetermined number (step S111). If the CPU 101 determines that the number of recorded objects 10 has not reached the predetermined number (NO in step S111), it repeats the operations from steps S107 to S111. If the CPU 101 determines that the number of recorded materials 10 has reached the predetermined number (YES in step S111), it stops heating the heat roller 33 (step S112), and also stops the transfer material conveyance section 30, the supply section 3, Then, the driving of the conveyance section 60 is stopped (step S113). With the above steps, the production of the recorded material 10 is completed.

[Processing executed by the inkjet recording device]
Next, the processing executed by the inkjet recording apparatus 1 will be explained in more detail using FIGS. 6 to 11. Here, each process of pre-transfer preparation, thermocompression bonding, first peeling, second peeling, and discharge will be explained.

[Pre-transfer preparation]
First, the pre-transfer preparation step will be explained using FIG. 6. FIG. 6 is a diagram showing a stage before the transfer material 5 and the recording material 55 are bonded under heat and pressure by the adhesive section 2. As shown in FIG. The transfer material position sensor Se6 detects the position of the transfer material 5 in order to synchronize with the operation of the recording section 7, and the CPU 101 controls each section based on the detection result. The transfer material position sensor Se6 includes, for example, a reflective or transmissive optical sensor, and detects markings recorded on the transfer material 5. Note that other position sensors have similar configurations. The transfer material 5 is conveyed in the direction of the arrow in FIG. 6 from the supply roller 32 and the transfer material transport roller 36 (step S106 in FIG. 5), and when the marking recorded on the transfer material 5 is detected by the transfer material position sensor Se6, the transfer material 5 has reached the recording position, and the image is recorded by the recording unit 7 (step S107 in FIG. 5).

The transfer material position sensor Se<b>5 detects the position of the transfer material 5 in order to synchronize the operation of the conveyance section 60 . The transfer material 5 on which the image has been recorded by the recording unit 7 is further conveyed in the direction of the arrow in the figure, and when the marking recorded on the transfer material 5 is detected by the transfer material position sensor Se5, the transfer material 5 has reached the pre-transfer position. Then, the drive of the transfer material conveying section 30 is stopped, and the conveyance of the transfer material 5 is stopped (step S108 in FIG. 5). During this time, since the heat roller 33 is in a position apart from the platen roller 63, the heat and pressure bonding process is not performed on the transfer material 5.

On the other hand, the recording materials 55 are sent out one by one to the conveyance path R2 by a pickup roller 66 and a pair of cleaning rollers 61 and 62. The recorded material position sensor Se1 detects whether or not the recorded material 55 has been sent out from the supply section 3. When the recording material position sensor Se1 detects the leading edge of the recording material 55, it drives the pair of transport rollers 22, 23 and the pair of transport rollers 24, 25 of the rotating section 20 to further transport the recording material 55, and also drives the pickup roller 66. Stops driving. At this time, since a clutch (not shown) is incorporated in the pickup roller 66 and rotates along with the direction in which the recording material 55 is pulled out, resistance to conveyance of the recording material 55 is reduced.

The recorded material position sensor Se2 detects the position of the recorded material 55 in order to synchronize the operations of the transfer material conveyance section 30 and the adhesive section 2. When the recording material position sensor Se2 detects the leading edge of the recording material 55, driving of the pair of cleaning rollers 61, 62, the pair of transport rollers 22, 23, and the pair of transport rollers 24, 25 is stopped (step S108 in FIG. 5). However, the transport roller pair 22, 23 and the transport roller pair 24, 25 do not necessarily need to stop driving, and can be transported to the bonding section 2 as they are.

[Heat pressure bonding]
Next, the process of heat-pressing the transfer material 5 and the recording material 55 will be described with reference to FIGS. 7 and 8. The transfer material 5 is stopped at the position where the marking is detected by the transfer material position sensor Se5, and the recording material 55 is in a state where the leading edge position of the recording material 55 is detected by the recording material position sensor Se2. ing. Here, as shown in FIG. 7, the heat roller 33 is moved to a position where the heat roller 33 contacts the platen roller 63 via the transfer material 5. When the transfer material 5 is transported in the direction of the arrow in FIG. 7 by the transfer material transport roller 36, the transport roller pair 22, 23 and the transport roller pair 24, 25 are driven in synchronization to transport the recording material 55. The recording material 55 that has entered the conveyance path R1 overlaps the surface of the ink receiving layer 53 of the transfer material 5, and enters between the heat roller 33 and the platen roller 63. The laminate 155 composed of the transfer material 5 and the recording material 55 is heat-pressed between the heat roller 33 and the platen roller 63 (step S109 in FIG. 5).

When the recording material position sensor Se2 detects the rear end of the recording material 55 in the first direction D1, the transport roller pair 22, 23 and the transport roller pair 24, 25 stop driving. As shown in FIG. 8, after the transfer material 5 and the recording material 55 are conveyed for a predetermined amount until the rear end of the recording material 55 passes between the heat roller 33 and the platen roller 63, the transfer material is conveyed. The driving of the unit 30 is stopped, and the heat roller 33 is moved to a position separated from the platen roller 63.

[Peeling]
Here, in the conventional technology (see Patent Document 1), when peeling the base material 50 from the laminate 155, the ink receiving layer 53 on the rear end side in the conveyance direction (for example, the second direction D2) of the laminate 155 is removed. could not be cut cleanly along the edge of the recording material 55, and there was a possibility that defective peeling would occur. This is because when peeling the base material 50, the peeling is performed in one direction (for example, the second direction D2), and the tip side in the second direction D2, which is the transport direction of the laminate 155, This is because, while a breaking force occurs in the ink receiving layer 53 along the edge of the recording material 55, no breaking force occurs in the ink receiving layer 53 at the rear end of the laminate 155 in the second direction D2. It is thought that Therefore, in this embodiment, the base material 50 can be stably peeled off from the laminate 155 by performing peeling at each of the leading and trailing ends of the laminate 155, and the ink-receiving layer can be removed along the edge of the recording material 55. 53 to be able to cut cleanly.

[First peeling]
The first peeling step of peeling off the base material 50 constituting the transfer material 5 will be described using FIG. 9. The transfer material 5 is transported by driving the supply roller 32, the transfer material transport roller 36, and the take-up roller 31 in the direction of the arrow in FIG. At this time, the recording material 55 is conveyed together with the transfer material 5 while being adhered to the transfer material 5 . When the leading edge in the first direction D1 of the laminate 155 in which the recording material 55 and the transfer material 5 are bonded under heat and pressure passes through the first peeling section 34, the base material 50 constituting the transfer material 5 and the unillustrated peeling are removed. The layer is peeled off, and the base material 50 and the peeling layer are temporarily wound onto the supply roller 32 side (step S109 in FIG. 5). When the laminated body 155 is conveyed a predetermined distance shorter than the length of the recording material 55 after the peeling is started, the conveyance is stopped.

[Second peeling]
Next, the second peeling process of peeling off the base material 50 constituting the transfer material 5 will be explained using FIG. 10. The transfer material 5 is transported by driving the supply roller 32, the transfer material transport roller 36, and the take-up roller 31 in the direction of the arrow in FIG. At this time, the recording material 55 is conveyed together with the transfer material 5 while being adhered to the transfer material 5 . When the leading end in the second direction D2 of the laminate 155 in which the recording material 55 and the transfer material 5 are bonded under heat and pressure passes through the second peeling section 44, the base material 50 constituting the transfer material 5 and the unillustrated peeling are removed. The layers are peeled off, and the base material 50 and peeling layer are wound up on the take-up roller 31 (step S110 in FIG. 5). By peeling the base material 50 from the laminate 155, the recorded matter 10 is formed. When the leading edge of the recorded object 10 in the second direction D2 is detected by the recorded object position sensor Se2, the conveying roller pair 22, 23 and the conveying roller pair 24, 25 are driven, and the rotating section 20 receives the recorded object 10. On the other hand, the transfer material 5 wound up by the take-up roller 31 stops being conveyed when the marking is detected by the transfer material position sensor Se5.

As described above, in the present embodiment, the control unit 100 adheres and transfers the transfer material 5 to the recording material 55 by the adhesive unit 2 to form the laminate 155, and then transports it in the first direction D1 to transfer the transfer material 5 to the recording material 55. A part of the base material 50 is peeled off from the downstream end of the laminate 155 by the first peeling section 34, and then transported in the second direction D2, and the second peeling section 44 peels off a part of the base material 50 from the downstream end of the laminate 155. All remaining base materials 50 are peeled off. However, the order is not limited to this, and the control unit 100 adheres and transfers the transfer material 5 to the recording material 55 using the adhesive unit 2 to form the laminate 155, and then transfers the transfer material 5 in the first direction D1 and the second direction. D2 (for example, second direction D2), and one of the first and second peeling parts 34 and 44 (for example, second peeling part 44) removes the layered product 155 from the downstream end. After peeling off the base material 50 of the section, it is conveyed in the other of the first direction D1 and the second direction D2 (for example, the first direction D1), and the other of the first peeling section 34 and the second peeling section 44 ( For example, all remaining base materials 50 may be peeled off from the upstream end of the laminate 155 in the opposite direction to the downstream end by the first peeling section 34).

Up to this point, it has been explained that the recording process is performed on one side of the recording material 55, but the recording process can also be performed on the other side. In this case, the rotary unit 20 is rotated 180 degrees to turn the recording material 55 upside down, and then the transport roller pair 22, 23 and the transport roller pair 24, 25 are driven, and the recording material position sensor Se2 detects the tip of the recording material 55. to stop at the detected position. On the other hand, the image on the second side is recorded on the transfer material 5 in the same operation as the image on the first side was recorded on the transfer material 5, synchronized with the recording material 55, and the same processing such as heat-pressing and peeling is performed. This makes it possible to record on both sides of the recording material 55.

[Emission]
Next, the process of discharging the recorded material 10 to the discharging section 4 will be explained using FIG. 11. As described above, the recorded material 10 is in a state of being delivered to the rotating section 20. The rotating part 20 rotates in the direction of the arrow in FIG. 11, and stops when a detected part (not shown) of the rotating part 20 is detected by the rotational position sensor Se8. The position of the rotational position sensor Se8 is set to match the conveyance path R3 through which the recorded material 10 can be discharged to the discharge section 4. Thereafter, the pair of conveyance rollers 22 and 23 and the pair of conveyance rollers 24 and 25 are driven to convey the recorded material 10 toward the discharge section 4. When the rear end of the recorded object 10 is detected by the ejection position sensor Se4, the recorded object 10 is ejected to the ejecting section 4, and the driving of the conveying roller pair 22, 23 and the conveying roller pair 24, 25 is stopped (see FIG. 5). Step S110). The rotating part 20 rotates in the direction opposite to the arrow in FIG. 10, and when the detected part is detected by the rotational position sensor Se7, it stops and prepares for the next operation. The position of the rotational position sensor Se7 is set so that the conveyance path of the recording material 55 coincides with the conveyance path R2 and the conveyance path R1.

As described above, according to the inkjet recording apparatus 1 of the present embodiment, the control unit 100 adheres and transfers the transfer material 5 to the recording material 55 using the adhesive unit 2 to form the laminate 155, and then transfers the transfer material 5 in the first direction. D1, a portion of the base material 50 is peeled off from the downstream end of the laminate 155 by the first peeling section 34, and then conveyed in the second direction D2, where the second peeling section 44 peels off the laminate 155. All remaining base materials 50 are peeled off from the downstream end of the body 155. Therefore, by performing peeling at each of the leading and trailing ends of the laminate 155, the base material 50 can be stably peeled from the laminate 155, and the ink receiving layer 53 can be neatly peeled off along the edge of the recording material 55. By making it possible to cut the base material 50, it is possible to suppress defective peeling when peeling the base material 50 from the laminate 155.

Further, according to the inkjet recording apparatus 1 of the present embodiment, the first peeling section 34 and the second peeling section 44 have a simple configuration using rollers, so an increase in the cost of the apparatus can be suppressed.

Here, as a reference example, conveyance rollers for conveying the recording material 55 are arranged before and after heat-pressing the transfer material 5 and the recording material 55, and the recording material 55 is always held between the conveyance rollers. A configuration is known in which transportation is carried out in the state of However, in such a configuration, the recording material 55 cannot be transported unless it is always held between one of the transport rollers, so it is necessary to set the distance between the transport rollers to be shorter than the minimum size length of the recording material 55. There is. Therefore, the number of conveying rollers increases, which complicates the configuration and leads to increased costs. Therefore, in this embodiment, by conveying the recording material 55 in a state in which it is adhered to the transfer material 5, it is possible to convey the recording material 55 over a distance longer than the minimum size length of the recording material 55 without using a conveyance roller. It is said that This makes it possible to stably transport the recording material 55 with an inexpensive configuration without providing a transport roller after passing through the heat roller.

Note that in the inkjet recording apparatus 1 of this embodiment, a case has been described in which the discharge section 4 is disposed below the supply section 3, but the present invention is not limited to this. For example, the discharge section 4 may be provided below the opposite side of the supply section 3 across the transport path R1. In this case, as shown in FIG. 12, a pair of conveyance rollers 64, 65 and a position sensor Se3 are provided on the left side of the first peeling section 34 in the figure, and the recorded matter 10 after transfer is transferred using the pair of conveyance rollers 64, 65. Alternatively, the materials may be discharged to the left side of the apparatus in the figure, and loaded onto a discharge section 4A provided below. When the rear end of the recorded object 10 is detected by the position sensor Se3, the conveyance of the recorded object 10 is stopped and preparations are made for the next operation. Also in this case, by peeling off both the front end side and the rear end side of the laminate 155, it is possible to suppress peeling defects when the base material 50 is peeled from the laminate 155.

<Second embodiment>
Next, a second embodiment of the present invention will be described in detail with reference to FIG. 13. This embodiment differs in configuration from the first embodiment in that the adhesive process by the adhesive section 2 is performed on both the tip end and the tip end of the laminate 155. However, other configurations, especially mechanical configurations, are the same as those in the first embodiment, so the reference numerals are the same and detailed explanations are omitted.

As described in the first embodiment, in the conventional technology (see Patent Document 1), when peeling the base material 50 from the laminate 155, The ink-receiving layer 53 on the rear end side could not be cut cleanly along the edge of the recording material 55, and there was a possibility that defective peeling would occur. This is due to the fact that heat and pressure are applied in one direction (the conveyance direction of the laminate) when the transfer material 5 and the recording material 55 are bonded together in the adhesive section 2. The leading end in the direction is nipped by hitting the nip between the heat roller 33 and the platen roller 63, whereas the trailing end in the conveying direction of the stacked body 155 is only released from the nipped state. It is thought that this is due to the fact that the pressure applied to the rear end is weaker than that of the front end, and that the adhesive is not sufficiently bonded. In this embodiment, attention is paid to this, and the front end side and the rear end side of the stacked body 155 are brought into contact with the nip portion, respectively, to increase the amount of pressure applied.

[Control flow of inkjet recording device]
The processing procedure in this embodiment will be explained according to the flowchart shown in FIG. In this embodiment as well, steps S101 to S108 up to just before the heat-press bonding process and steps S111 to S113 after the completion of printing one sheet are the same processes as in the first embodiment, so the same reference numerals are used to explain the details. Further explanations will be omitted. Note that in this embodiment, when peeling the base material 50 from the laminate 155, unlike the first embodiment, the first peeling part 34 is not used, but only the second peeling part 44, which is an example of a peeling part, is used. Is going. That is, in this embodiment, the first peeling part 34 may not be provided. However, the present invention is not limited to this, and both the first peeling section 34 and the second peeling section 44 may be used similarly to the first embodiment.

The transfer material 5 and the recording material 55 on which the image has been recorded are once stopped at a predetermined position, and thereby their respective positions are aligned (step S108). Due to this positioning, the ink receiving layer 53 of the transfer material 5 overlaps the recording material 55, is conveyed in the first direction D1, and is fed into the nip formed by the heat roller 33 and the platen roller 63. While the recording material 55 and the transfer material 5 pass between the heat roller 33 and the platen roller 63, the recording material 55 and the transfer material 5 are heated and pressed together to form a laminate 155 (step S114, heat and pressure bonding step). , adhesive treatment). More specifically, when the recording material position sensor Se2 detects the rear end of the recording material 55, the transport roller pair 22, 23 and the transport roller pair 24, 25 stop driving. After conveying the transfer material 5 and the recording material 55 for a predetermined amount until the rear end of the recording material 55 passes between the heat roller 33 and the platen roller 63, the driving of the transfer material conveying section 30 is stopped, and the heat The roller 33 is moved to a position separated from the platen roller 63.

The recording material 55 is stopped at a position where the rear end passes between the heat roller 33 and the platen roller 63, and the recording material 55 is in a state of being adhered to the transfer material 5. Further, the heat roller 33 is in a stopped state at a position separated from the platen roller 63. Here, the heat roller 33 contacts the platen roller 63 via the transfer material 5. In the above-mentioned heat-press bonding process, the heat roller 33 is separated from the platen roller 63 after heat-press bonding, but the present invention is not limited to this. You may re-heat and press-bond as is.

When the transfer material 5 is reversely conveyed in the second direction D2 by the transfer material conveying roller 36, together with the recording material 55 adhered to the transfer material 5, the rear end side of the recording material 55 opposite to the heat and pressure bonding process (see FIG. The middle right side) enters the nip between the heat roller 33 and the platen roller 63 first. At this time, the end portion on the opposite side from the first time enters the nip portion, so that a pressurizing process is performed in which the tip portion of the recording material 55 in the second direction D2 is pressed by the nip portion of the adhesive portion 2. While the recording material 55 and the transfer material 5 pass between the heat roller 33 and the platen roller 63, the recording material 55 and the transfer material 5 are heated and pressed again (step S115, reheating and pressing step). After the recording material 55 is stopped at a position where it has been moved by a predetermined amount and does not exceed the second peeling section 44, driving of the transfer material conveying section 30 is stopped and the heat roller 33 is moved to a position where the heat roller 33 is separated from the platen roller 63. Move to. At this time, the operation is stopped for a predetermined time in order to cool the recording material 55 and the transfer material 5 (step S116). Thereafter, the transfer material 5 starts to be conveyed in the second direction D2, and the laminate 155 is conveyed to the second peeling section 44, where the base material 50 is peeled off to become a recorded object 10 (final recorded object), and the stacked body 155 is conveyed to the second peeling section 44, where the base material 50 is peeled off to become a recorded object 10 (final recorded object), 4 (step S117).

The conditions for heat compression bonding and reheat compression bonding may be the same or may be different. In this embodiment, the adhesive part 2 includes a temperature control means (not shown) that controls the temperature of the heat roller 33 and a pressure control means (not shown) that controls the pressure generated by the contact between the heat roller 33 and the platen roller 63. It is equipped with Further, the transfer material conveyance section 30 includes a speed control means (not shown) that controls the conveyance speed of the transfer material 5. Therefore, using these control means, various conditions during the reheating and pressing process may be changed with respect to those during the heating and pressing process. For example, the pressure applied to the recording material 55 and the transfer material 5 due to the contact between the heat roller 33 and the platen roller 63 during reheating and pressure bonding is smaller than that during heat and pressure bonding because a predetermined pressure has already been applied during heat and pressure bonding. It becomes possible to crimp with. That is, the control unit 100 can set the pressure applied by the adhesive part 2 during the pressure treatment to the second pressure, which is lower than the first pressure that is the pressure applied during the adhesive treatment. Further, the control unit 100 can set the heating temperature by the adhesive part 2 during the pressure treatment to a second temperature lower than the first temperature, which is the heating temperature during the adhesive treatment. Further, the control unit 100 can set the conveyance speed of the transfer material 5 in the pressure treatment to a second speed that is faster than the first speed, which is the conveyance speed in the adhesion treatment.

In the present embodiment, the control unit 100 causes the transfer material conveyance unit 30 to transport the transfer material 5 and the recording material 55 in a stacked manner in the first direction D1, and causes the transfer material 5 and the recording material 55 to A laminate 155 is formed by performing an adhesion process. After the formed laminate 155 passes through the adhesive section 2, the laminate 155 is reversely conveyed in the second direction D2 by the transfer material conveyance section 30, and the leading end of the laminate 155 in the second direction D2 is A pressurizing process is performed in which the adhesive enters the nip portion of the adhesive portion 2 and pressurizes it. Further, in the present embodiment, the control unit 100 causes the tip end of the laminate 155 in the second direction D2 to enter the nip portion of the adhesive portion 2, and then the entire laminate 155 moves into the nip portion. The roller pair 2a of the heat roller 33 and the platen roller 63 is separated from each other before passing through. Further, in the pressurizing process, after separating the roller pair 2a from each other, the control unit 100 waits for a predetermined time and cools the roller pair.

As described above, according to the inkjet recording apparatus 1 of the present embodiment, the control section 100 causes the transfer material conveying section 30 to transport the laminate 155 in the second direction D2 after the laminate 155 passes through the adhesive section 2. Then, a pressurizing process is performed in which the tip of the laminate 155 in the second direction D2 enters the nip portion of the adhesive portion 2 and pressurizes it. Therefore, the rear end portion of the recording material 55 in the first direction D1 is brought into contact with the nip portion of the roller pair 2a, so that the edge portion of the rear end portion can be sufficiently pressed. Thereby, sufficient adhesive force can be ensured without changing the basic configuration of the inkjet recording apparatus 1, and peeling failures when peeling the base material 50 from the laminate 155 can be suppressed.
