In step S1, print information is received. The control unit 1 receives and stores the input of print data for printing an image on the medium 95 from the input device 6 and print information including the type and print mode of the medium 95 in the storage unit 4.

In step S2, the elevating device 92 is lowered. The control unit 1 controls the elevating device 92 to lower the rod 92a of the elevating device 92 (air cylinder). As a result, the medium 95
Is pressed against the transport belt 23 by the heating pressing portion 61.

In step S3, the heater 61a is operated based on the width of the medium 95. Step S1
The print information received in the above includes information on the cloth width of the medium 95 and the edge processing of the cloth. The control unit 1 changes the temperature for each of the plurality of heaters 61a according to the cloth width. For example, when a medium 95 having a fabric width narrower than the width of the transport belt 23 is used, the temperature of the heater 61a provided at a position where the medium 95 is not placed is lowered or the operation is stopped. This will result in
The power consumption of the printing apparatus 100 can be reduced. Further, since the adhesive 29 in the portion where the medium 95 is not placed is not heated and the adhesive strength remains low, it is possible to reduce the adhesion of dust in this portion.

Further, since the end portion of the medium 95 in the crossing direction is easily dissipated, the heat from the heating pressing portion 61 is difficult to be transferred to the adhesive 29 of the transport belt 23 via the medium 95. When the end portion of the medium 95 is folded back, it becomes more difficult for heat to be transferred to the pressure-sensitive adhesive 29. Therefore, the control unit 1 abuts the temperature of the heater 61a provided at the abutting position where the heating pressing portion 61 abuts on the end portion of the medium 95, depending on the width of the medium 95 and the information on the end portion processing. The temperature is higher than the temperature of the heater 61a provided at a position other than the position. As a result, heat is suitably transferred from the heating pressing portion 61 to the pressure-sensitive adhesive 29, so that the medium 95 easily adheres to the transport belt 23 via the pressure-sensitive adhesive 29.

In step S4, the temperature of the heating pressing portion 61 is changed based on the type of the medium 95. The print information received in step S1 includes information on the fabric type and fabric thickness of the medium 95.
Further, in the storage unit 4, a table showing the relationship between the dough type and the dough thickness and the temperature of the heating pressing unit 61 is stored in the storage unit 4 in advance. In the storage unit 4, in addition to the cotton fabric type exemplified in FIG. 8, similar tables are stored for each fabric type such as silk, wool, and polyester.

The control unit 1 changes the temperature of the heating pressing unit 61 with reference to the table stored in the storage unit 4 based on the type of the medium including the information on the dough type and the dough thickness of the received medium 95. Specifically, the control unit 1 is, for example, when the medium 95 is "fabric type: cotton" and "fabric thickness: medium".
The temperature of the heating pressing unit 61 is set to "medium", and the voltage applied to the heater 61a is controlled based on the temperature detected by the temperature detecting unit 69a. As a result, media with different fabric types and thicknesses 95
Even when the above is used, heat is transferred to the pressure-sensitive adhesive 29 without damaging the texture of the medium 95, so that the medium 95 can be suitably brought into close contact with the transport belt 23. When the medium 95 is "dough type: cotton" and "dough thickness: thick", the temperature of the heating pressing portion 61 is set to "high". This is because when the medium 95 is thick, a large amount of energy is required for heating. When the medium 95 is "dough type: cotton" and "dough thickness: thin", the temperature of the heating pressing portion 61 is set to "low". This is because when the medium 95 is thin, the energy required for heating is small.

In step S5, the moving speed of the heating pressing portion 61 is set. The control unit 1 is a heating pressing unit 6.
The speed at which 1 is moved is set to a predetermined moving speed, and the moving mechanism 62 is controlled to control the heating pressing unit 61.
Is swung at a predetermined moving speed within the moving range L1. For convenience of explanation, steps S2 to S5 have been described in different steps, but steps S2 to S have been described.
5 is performed substantially at the same time.

In step S6, printing is performed. The control unit 1 controls the head unit 42 and the carriage moving unit 45 based on the print data received in step S1 to move the head unit 42 while ejecting ink from the ejection head, and the belt drive roller 25. The sub-scanning in which the medium 95 is conveyed in the conveying direction by controlling the above is alternately repeated. By this printing operation, an image or the like is printed on the medium 95. The medium 95 is intermittently conveyed during the printing operation, and the transfer is stopped during the main scanning. Even when the transport of the medium 95 is stopped, the heating pressing portion 61 repeatedly moves (swings) in the transport direction, so that the heat marks on the medium 95 are suppressed.

In step S7, the heater 61a and the moving mechanism 62 are stopped. When the printing in step S6 is completed, the control unit 1 stops driving the heater 61a and the moving mechanism 62.

In step S8, the elevating device 92 is raised. When the printing operation is stopped, the control unit 1 controls the elevating device 92 (air cylinder) to raise the rod 92a, and the heating pressing unit 6
1 is separated from the medium 95. As a result, it is possible to prevent the medium 95 from having heating marks. Although steps S7 and S8 have been described in different steps for convenience of explanation, steps S7 and S8 are performed substantially at the same time.

As described above, according to the printing apparatus 100 according to the present embodiment, the following effects can be obtained.
The printing apparatus 100 includes a heating pressing portion 61 that heats the medium 95 and presses it against the transport belt 23.
It has a control unit 1 that moves the heating pressing unit 61 along the transport direction. Even when the transport of the medium 95 is stopped, the heating pressing unit 61 repeatedly moves (swings) in the transport direction by the moving mechanism 62 controlled by the control unit 1. As a result, the medium 95 is marked with heating marks, and the medium 95 is formed.
It is possible to prevent the texture of the material from being impaired.

The transport belt 23 of the printing apparatus 100 is coated with an adhesive 29 whose adhesiveness increases by heating. The pressure-sensitive adhesive 29 is heated by the heat from the heating pressing portion 61 swinging in the transport direction, and the medium 95 is pressed against the pressure-sensitive adhesive 29 on the transport belt 23 by the heating pressing portion 61, so that the medium 95 is pressed against the transport belt 23. It can be suitably attached.
The printing apparatus 100 includes a contact portion 69 that indirectly contacts the heating pressing portion 61 via the transport belt 23 at a position including the moving range L1 of the heating pressing portion 61. As a result, even when the heating pressing portion 61 is moved (swinged) in the transport direction, the medium 95, the transport belt 23, and the adhesive 29 are suitably heated between the heating pressing portion 61 and the contact portion 69. Can be pressed.

The printing apparatus 100 includes a temperature detection unit 69a that detects the temperature of the transport belt 23.
By controlling the heater 61a based on the temperature detected by the temperature detection unit 69a, the control unit 1 can keep the transfer belt 23 at a predetermined temperature.
The control unit 1 changes the temperature of the heating pressing unit 61 based on the type of the medium 95 (dough type, dough thickness). As a result, heat is transferred to the adhesive 29 without damaging the texture of the medium 95, so that the medium 95 can be suitably brought into close contact with the transport belt 23.

The heating pressing portion 61 is provided with a plurality of heaters 61a. The control unit 1 is, for example,
Since the number and temperature of the heaters 61a to be operated are changed according to the width of the medium 95, the printing apparatus 1
The power consumption of 00 can be reduced.
Further, in the control unit 1, the heating pressing unit 61 is the medium 9 according to the information on the width of the medium 95 and the end processing.
The temperature of the heater 61a provided at the contact position in contact with the end portion of 5 is set higher than the temperature of the heater 61a provided at a position other than the contact position. As a result, heat is suitably transferred from the heating pressing portion 61 to the pressure-sensitive adhesive 29, so that the medium 95 easily adheres to the transport belt 23.
When the control unit 1 stops the printing operation, the elevating device 92 is raised to separate the heating pressing unit 61 from the medium 95, so that it is possible to suppress the formation of heating marks on the medium 95.

The present invention is not limited to the above-described embodiment, and various changes and improvements can be made to the above-mentioned embodiment. A modification example is described below.

(Modification 1)
FIG. 9 is a flowchart illustrating a printing method of the printing apparatus according to the first modification. FIG. 10
Is a table showing the relationship between the dough type and the dough thickness and the moving speed of the heating pressing portion. The printing method of the printing apparatus 100 described in this modification is different from the embodiment in that the moving speed of the heating medium portion 61 is changed according to the type (dough type) of the medium 95 and the thickness of the dough.
Hereinafter, the printing method of the printing apparatus 100 according to the first modification will be described with reference to FIGS. 9 and 10. Since the configuration of the printing apparatus 100 is the same as that of the embodiment, the description thereof will be omitted. Further, in the flowchart shown in FIG. 9, steps S101 to S103 are the same as steps S1 to S3 described in the embodiment, and steps S106 to S1
Since 08 is the same as steps S6 to S8 described in the embodiment, the description thereof will be omitted.

In step S104, the temperature of the heating pressing portion 61 is set. The control unit 1 is a heating pressing unit 6.
The temperature for heating 1 is set to a predetermined temperature, and the voltage applied to the heater 61a is controlled based on the temperature detected by the temperature detection unit 69a. As a result, the heating pressing portion 61 is heated to a predetermined temperature, and that temperature is maintained.

In step S105, the moving speed of the heating pressing portion 61 is changed based on the type of the medium 95. The print information received in step S101 includes information on the fabric type and fabric thickness of the medium 95. Further, in the storage unit 4, a table showing the relationship between the dough type and the dough thickness and the moving speed when the heating pressing unit 61 is shaken is stored in the storage unit 4 in advance. FIG. 1 is stored in the storage unit 4.
In addition to the cotton fabric types exemplified in 0, similar tables are stored for each fabric type such as silk, wool, and polyester.

The control unit 1 changes the moving speed of the heating pressing unit 61 with reference to the table stored in the storage unit 4 based on the type of the medium including the information on the dough type and the dough thickness of the received medium 95. Specifically, when the medium 95 is, for example, "fabric type: cotton" and "fabric thickness: medium", the control unit 1 sets the moving speed of the heating pressing unit 61 to "medium" and sets the moving mechanism 62. Controlled heating pressing unit 6
1 is swung at a "medium" movement speed within the movement range L1. As a result, heat is transferred to the adhesive 29 without damaging the texture of the medium 95, so that the medium 95 can be suitably brought into close contact with the transport belt 23. In addition, the medium 95 is "fabric type: cotton", "fabric thickness: thick".
In the case of, the moving speed of the heating pressing portion 61 is set to “slow”. This is because when the medium 95 is thick, a large amount of energy is required for heating, so that the contact time between the medium 95 and the heating pressing portion 61 is lengthened. When the medium 95 is "fabric type: cotton" and "fabric thickness: thin", the moving speed of the heating pressing portion 61 is set to "slow". If the medium 95 is thin, wrinkles and the like are likely to occur and transportation becomes difficult. Therefore, the transport amount of the medium 95 per unit time tends to be small (the transport speed becomes slow). Therefore, the moving speed of the heating pressing portion 61 is slowed down. However, if the medium 95 is thin but easy to transport and the transport amount of the medium 95 per unit time can be large (fast transport speed), the heating pressing portion 61 can be used in the case of "fabric thickness: thin". The movement speed may be set to "fast".

(Modification 2)
FIG. 11 is a flowchart illustrating a printing method of the printing apparatus according to the second modification. Figure 1
Reference numeral 2 is a table showing the relationship between the fabric type and the printing mode and the temperature of the heating pressing portion. The printing method of the printing apparatus 100 described in this modification is the type (fabric type) of the medium 95 and the printing mode (
It is different from the embodiment in that the temperature of the heating medium unit 61 is changed according to the printing speed).
Hereinafter, the printing method of the printing apparatus 100 according to the second modification will be described with reference to FIGS. 11 and 12. Since the configuration of the printing apparatus 100 is the same as that of the embodiment, the description thereof will be omitted.
Further, in the flowchart shown in FIG. 11, steps S201 to S203 are the same as steps S1 to S3 described in the embodiment, and steps S205 to S208 are the same as steps S5 to S8 described in the embodiment. Since there is, the explanation is omitted.

In step S204, the temperature of the heating pressing portion 61 is changed based on the printing speed. The print mode (print information) received in step S201 includes information on the printing speed to be printed by the printing unit 40. Further, in the storage unit 4, a table showing the relationship between the fabric type and the printing mode and the temperature of the heating pressing unit 61 is stored in the storage unit 4 in advance. In the storage unit 4, in addition to the cotton fabric type exemplified in FIG. 12, similar tables are stored for each fabric type such as silk, wool, and polyester.

The control unit 1 changes the temperature of the heating pressing unit 61 with reference to the table stored in the storage unit 4 based on the received information on the fabric type of the medium 95 and the printing speed included in the printing mode.
The printing speed is set to the medium 95 in one sub-scan in the sub-scan in which the medium 95 is conveyed in the transport direction.
Corresponds to the amount of transportation. That is, the printing speed is the transport amount (transport speed) per unit time. When the print mode is "super high image quality", the printing speed is slower than "high image quality" (the amount of transport per unit time is small), and when the print mode is "fast", the printing speed is "high image quality". It means that it is faster than (the amount of transportation per unit time is large).
Specifically, in the control unit 1, for example, the medium 95 is "fabric type: cotton", "printing mode::
In the case of "high image quality", the temperature of the heating pressing unit 61 is set to "medium", and the voltage applied to the heater 61a is controlled based on the temperature detected by the temperature detecting unit 69a. As a result, heat is transferred to the adhesive 29 without damaging the texture of the medium 95, so that the medium 95 can be suitably brought into close contact with the transport belt 23. When the medium 95 is "fabric type: cotton" and "printing mode: ultra-high image quality", the temperature of the heating pressing portion 61 is set to "low". When the printing mode is "ultra-high image quality", the printing speed is slow and the contact time between the medium 95 and the heating pressing portion 61 becomes long.
This is because sufficient heating can be performed even if the temperature of the heating pressing portion 61 is low. Further, the medium 95 is "
In the case of "fabric type: cotton" and "printing mode: fast", the temperature of the heating pressing portion 61 is set to "high". When the print mode is "fast", the print speed is high, and the medium 95 and the heating pressing portion 61 are used.
This is because it is preferable to raise the temperature of the heating pressing portion 61 in order to perform sufficient heating because the contact time with the heating is shortened.

(Modification 3)
FIG. 13 is a flowchart illustrating a printing method of the printing apparatus according to the modified example 3. Figure 1
Reference numeral 4 is a table showing the relationship between the fabric type and the printing mode and the moving speed of the heating pressing portion.

In step S304, the temperature of the heating pressing portion 61 is set. The control unit 1 is a heating pressing unit 6.
The temperature for heating 1 is set to a predetermined temperature, and the voltage applied to the heater 61a is controlled based on the temperature detected by the temperature detection unit 69a. As a result, the heating pressing portion 61 is heated to a predetermined temperature, and that temperature is maintained.

In step S305, the moving speed of the heating pressing unit 61 is changed based on the printing speed. The print mode (print information) received in step S301 includes information on the printing speed to be printed by the printing unit 40. Here, the relationship between the print mode and the print speed is the same as that of the second modification. Further, in the storage unit 4, a table showing the relationship between the fabric type and the printing mode and the moving speed when the heating pressing unit 61 is shaken is stored in the storage unit 4 in advance. In the storage unit 4,
In addition to the cotton fabric types exemplified in FIG. 14, similar tables are stored for each fabric type such as silk, wool, and polyester.

The control unit 1 changes the moving speed of the heating pressing unit 61 with reference to the table stored in the storage unit 4 based on the received information on the fabric type of the medium 95 and the printing speed included in the printing mode. Specifically, when the medium 95 is, for example, "fabric type: cotton" and "printing mode: high image quality", the control unit 1 sets the moving speed of the heating pressing unit 61 to "medium", and the moving mechanism 62. Is controlled to swing the heating pressing portion 61 at a moving speed of "medium" within the moving range L1. As a result, heat is transferred to the adhesive 29 without damaging the texture of the medium 95, so that the medium 95 can be suitably brought into close contact with the transport belt 23. In addition, the medium 95 is "fabric type: cotton",
In the case of "print mode: ultra-high image quality", the moving speed of the heating pressing unit 61 is set to "slow".
When the printing mode is "ultra-high image quality", the printing speed is slow and the contact time between the medium 95 and the heating pressing portion 61 is long, so that sufficient heating can be performed even if the moving speed of the heating pressing portion 61 is slow. be. When the medium 95 is "fabric type: cotton" and "printing mode: fast", the moving speed of the heating pressing portion 61 is set to "fast". When the printing mode is "fast", the printing speed is high and the contact time between the medium 95 and the heating pressing portion 61 is short. Therefore, in order to perform sufficient heating, the moving speed of the heating pressing portion 61 may be increased. This is preferable.

(Modification example 4)
FIG. 15 is a flowchart illustrating a printing method of the printing apparatus according to the modified example 4. Figure 1
Reference numeral 6 is a table showing the relationship between the fabric type and the printing mode and the moving range of the heating pressing portion. The printing method of the printing apparatus 100 described in this modification is different from the embodiment in that the moving range of the heating medium unit 61 is changed according to the type (fabric type) of the medium 95 and the printing mode (printing speed).
Hereinafter, the printing method of the printing apparatus 100 according to the modified example 4 will be described with reference to FIGS. 15 and 16. Since the configuration of the printing apparatus 100 is the same as that of the embodiment, the description thereof will be omitted.
Further, in the flowchart shown in FIG. 15, steps S401 to S403 are the same as steps S1 to S3 described in the embodiment, and steps S406 to S408 are the same as steps S6 to S8 described in the embodiment. Since there is, the explanation is omitted.

In step S404, the temperature of the heating pressing portion 61 is set. The control unit 1 is a heating pressing unit 6.
The temperature for heating 1 is set to a predetermined temperature, and the voltage applied to the heater 61a is controlled based on the temperature detected by the temperature detection unit 69a. As a result, the heating pressing portion 61 is heated to a predetermined temperature, and that temperature is maintained.

In step S405, the moving range of the heating pressing portion 61 is changed based on the printing speed. The print mode (print information) received in step S401 includes information on the printing speed to be printed by the printing unit 40. Here, the relationship between the print mode and the print speed is the same as that of the second modification. Further, in the storage unit 4, a table showing the relationship between the fabric type and the printing mode and the moving range when the heating pressing unit 61 is shaken is stored in the storage unit 4 in advance. In the storage unit 4,
In addition to the cotton fabric types exemplified in FIG. 16, similar tables are stored for each fabric type such as silk, wool, and polyester.

Based on the received information on the fabric type of the medium 95 and the printing speed included in the printing mode, the control unit 1 refers to the table stored in the storage unit 4 and changes the moving range of the heating pressing unit 61 in the transport direction. do. Specifically, in the control unit 1, for example, the medium 95 is "fabric type: cotton", "
In the case of "print mode: high image quality", the moving range of the heating pressing portion 61 is set to "medium", and the moving mechanism 6 is set.
2 is controlled to swing the heating pressing portion 61 within the "middle" movement range. As a result, heat is transferred to the adhesive 29 without damaging the texture of the medium 95, so that the medium 95 can be suitably brought into close contact with the transport belt 23. Further, when the medium 95 is "fabric type: cotton" and "printing mode: ultrahigh image quality", the moving range of the heating pressing portion 61 is set to "narrow". This is because when the print mode is "ultra-high image quality", the amount of heat transported per unit time is small, and it is preferable that the moving range of the heating pressing portion 61 is narrowed accordingly. When the medium 95 is "fabric type: cotton" and "printing mode: fast", the moving range of the heating pressing portion 61 is set to "wide". This is because when the print mode is "ultra-high image quality", the amount of heat transported per unit time is large, and it is preferable that the moving range of the heating pressing portion 61 is widened accordingly.
