FIG. 1 is a perspective explanatory view when a cassette is attached to the printing device of the image imparting device, and FIG. 2 is a perspective explanatory view when the cassette is removed and inserted into the heating device after printing by the printing device is completed.

The image giving device (image giving system) 1000 includes a cassette 200 which is a holding member), a printing device 1, and a heating device 500. The cassette 200 is a cloth holding member that holds a printed portion of the cloth 400, which is a printing object, in a flat state, and is shared by both the printing device 1 and the heating device 500.

The printing device 1 has a removable cassette 200 and prints an image on the cloth 400 held in the cassette 200. In the heating device 500, the cassette 200 is removable, and the printed fabric 400 is heated together with the cassette 200 to fix the image.

Although the printing device 1 is shown here in a state where the printing device 1 is placed on the heating device 500, the printing device 1 and the heating device 500 are separate bodies and may be arranged side by side or separated from each other. It can also be placed in a position.

When an image is given to the cloth 400 by the image giving device 1000, as shown in FIG. 1, the cassette 200 holding the cloth 400 is set (mounted) on the stage 111 of the printing device 1, and the printing device 1 sets (mounts) the cassette 200 on the cloth 400. Print the image.

When the printing of the image on the cloth 400 by the printing device 1 is completed, the front door 502 of the heating device 500 is opened, the cassette 200 holding the cloth 400 is taken out from the printing device 1, and as it is, as shown in FIG. The cassette 200 is inserted into the heating device 500. Then, after the cassette 200 is housed in the heating device 500, the front door 502 of the heating device 500 is closed, and the heating device 500 heats the fabric 400 together with the cassette 200. By heating the cloth 400, the image printed on the cloth 400 is fixed on the cloth 400.

As described above, the cassette 200, which is a fabric holding member, can be shared by both the printing device 1 and the heating device 500.

As a result, the printed fabric 400 can be held in the state at the time of printing and set in the heating device 500, and even if the fabric 400 is carried, wrinkles may occur or parts of the fabric 400 may overlap and the printed surface may be disturbed. However, the workability of imparting an image to the fabric 400 is improved.

Next, an example of the printing apparatus will be described with reference to FIGS. 3 and 4. FIG. 3 is a perspective explanatory view for explaining the overall configuration of the mechanical portion of the printing apparatus, and FIG. 4 is a perspective explanatory view which is also viewed from a direction different from that of FIG.

The printing apparatus 1 has a stage 111, which is a receiving member that detachably holds a cassette 200 holding the fabric 400 and moves back and forth in the apparatus main body 100, and a fabric held by the cassette 200 held by the stage 111. It is provided with a printing means 112 for printing on the 400.

Here, the cloth 400 is not only a piece of cloth such as a handkerchief or a towel, but also a part of a product such as a cloth processed as clothes such as a T-shirt or a trainer, or a tote bag. You can also use the existing fabric.

The stage 111 is provided on the transport structure 113 held so as to be reciprocally movable in the arrow Y direction (feed direction) with respect to the apparatus main body 100.

Here, the transport guide member 115 is arranged on the bottom housing portion 114 of the apparatus main body 100 along the arrow Y direction, and the slider portion 116 of the transport structure 113 is movably held by the transport guide member 115.

The printing means 112 includes a carriage 121 that moves in the direction of arrow X (main scanning direction) with respect to the stage 111, and a head 122 mounted on the carriage 121.

The carriage 121 is movably held by a guide member 123 arranged along the arrow X direction, and is reciprocated in the arrow X direction by a drive motor 124 via a scanning mechanism such as a timing belt 125. The head 122 uses a liquid ejection head to eject ink onto the surface of the fabric to form an image, but the head 122 is not limited to this.

In the printing apparatus 1, the cassette 200 is mounted and held on the stage 111 in the apparatus main body 100 in a state where the fabric 400 is set on the platen member 300 of the cassette 200. Then, the required image is printed on the fabric 400 by repeating the movement of the stage 111 in the arrow Y direction and the reciprocating movement of the head 122 in the arrow X direction.

In this case, the stage 111 can be raised and lowered in the direction of arrow Z, and the gap between the cloth 400 and the head 122 can be adjusted to a predetermined gap by raising and lowering the stage 111 according to the thickness of the cloth 400. The printing means 112 can also be raised and lowered.

Next, an example of the heating device will be described with reference to FIGS. 5 and 6. FIG. 5 is a cross-sectional explanatory view along the longitudinal direction (cassette loading / unloading direction) of the heating device, and FIG. 6 is a cross-sectional explanatory view along the lateral direction (direction orthogonal to the cassette loading / unloading direction) of the heating device.

The heating device 500 is held in the receiving member 503 to which the cassette 200 holding the cloth 400 to which the image is attached is detachably attached (meaning including simple mounting) and the cassette 200 inside the device main body 501. A heater 504, which is a heating means for heating the cloth 400, is arranged.

The heater 504 faces the platen member 300 of the cassette 200 and heats the fabric 400 held on the platen member 300 in a non-contact manner.

A flat member made of a material having excellent thermal conductivity such as aluminum is provided on the cassette 200 side of the heater 504, and the heater 504 heats the heat so that the surface temperature becomes substantially uniform. You can also. By doing so, it is possible to heat at substantially the same temperature in the plane regardless of the heating position of the heater 504.

Next, the cassette which is a cloth holding member will be described with reference to FIGS. 7 to 9. 72 is an external perspective view of the cassette, FIG. 8 is a perspective explanatory view of the cassette with the outer peripheral cover member open, and FIG. 9 is a schematic cross-sectional explanatory view of the cassette along the lateral direction.

The cassette 200 includes a base member 201, a platen member 300 that holds a portion of the fabric 400 to be printed in a flat state, and an outer peripheral cover member 202 that sandwiches the fabric 400 between the platen members 300. ..

The platen member 300 is composed of a platen structure 302 and a heat insulating member 301 constituting a surface (holding surface) 300a for holding the fabric 400 in a flat state. The heat insulating member 301 has heat resistance to heating by the heating device 500.

The outer peripheral cover member 202 has a frame portion 202b forming an opening 202a through which the platen member 300 is exposed. The outer peripheral cover member 202 is provided so as to be openable and closable with respect to the base member 201 by a hinge 203 or the like. The outer peripheral cover member 202 sandwiches and presses the fabric 400 with the flange portion 300b of the peripheral portion of the platen member 300.

The platen member 300 is supported by the support portion 311 with respect to the base member 201, and a storage space 312 capable of accommodating the surplus portion 400a of the fabric 400 is formed between the platen member 300 and the base member 201. The surplus portion 400a corresponds to both sleeves, a collar opening, a hem, and the like, for example, when printing is performed on the front surface of a T-shirt.

Further, the support portion 311 that supports the platen member 300 includes a hollow strut portion 231 on the base member 201 side, a hollow strut portion 331 on the platen member 300 side that is movably fitted to the hollow strut portion 231 and a hollow strut portion 231. It is provided with a compression spring 332 arranged between the hollow column portion 331 and the hollow support portion 331.

As a result, the platen member 300 is displaceably supported with respect to the base member 201. Therefore, when the thickness of the fabric 400 changes, the platen member 300 descends against the restoring force of the spring 332 to change the distance from the base member 201, and it is possible to cope with the fabric 400 having a different thickness.

Here, the platen member 300 is removable from the base member 201 and is formed to be replaceable. As a result, a plurality of platen members 300 can be prepared, and clothing can be wrapped around another platen member 300 during the printing operation. After printing and fixing are completed, the platen member 300 can be replaced to quickly print the next fabric. You can start.

When the fabric 400 is held in the cassette 200 for printing, first, the outer peripheral cover member 202 is opened, and the printing portion of the fabric 400 is placed on the platen member 300. After that, the extra portion (surplus portion) 400a of the fabric 400 is pushed into the accommodation space 312 from the direction of the arrow, and the excess portion 400a is accommodated in the accommodation space 312. Then, the outer peripheral cover member 202 is closed.

As a result, the printed portion of the fabric 400 is held in a flat state by the platen member 300, and the surplus portion 400a is housed in the cassette 200 without protruding to the outside.

Then, when printing on the fabric 400, the cassette 200 in which the fabric 400 is set is mounted (set) on the stage 111 of the apparatus main body 100 of the printing apparatus 1. At this time, since the cassette 200 can be mounted on the stage 111 from the moving direction of the stage 111, the entire stage 111 can be moved out of the apparatus main body 100 as compared with the configuration in which the cassette 200 is mounted on the stage 111 from directly above the stage 111. There is no need to expose it, and the device can be downsized.

As described above, since the cloth 400 to be printed can be set on the platen member 300 with the entire cassette 200 taken out from the apparatus main body 100, the work of setting the cloth 400 on the platen member 300 can be easily performed. Become.

Next, the first embodiment of the present invention will be described with reference to FIGS. 10 to 12. 10 is a schematic explanatory view of the printing apparatus according to the embodiment, FIG. 11 is an explanatory diagram of a stage elevating mechanism of the printing apparatus, and FIG. 12 is an explanatory diagram for explaining the stage height detecting means.

As described above, the printing apparatus 1 includes a stage 111 as a receiving member for detachably mounting the cassette 200 in the apparatus main body 100.

The stage 111 is arranged on the slider portion 116 of the transport structure 113. Here, the slider portion 116 can be reciprocated in the Y direction by the drive mechanism 130. The drive mechanism 130 includes a timing belt 133 hung between the pulleys 131 and 132, and a motor 134 for rotationally driving the pulley 131.

Therefore, by driving the motor 134, the cassette 200 mounted on the stage 111 and the fabric 400 held by the cassette 200 are reciprocated in the Y direction via the drive mechanism 130, the slider portion 116, and the stage 111. Can be done.

That is, the reciprocating moving means for reciprocating the cassette 200 holding the fabric 400 with respect to the printing means 112 between the attachment / detachment position and the standby position by the stage 111, the transport structure 113 including the slider portion 116, the drive mechanism 130, and the like. It constitutes 110.

A linear encoder is configured by an encoder scale 136 arranged along the reciprocating movement range of the stage 111 and an encoder sensor 135 provided in the slider unit 116 (or stage 111) for reading the encoder scale 136 provided in the slider unit 116. , The Y-direction position of the stage 111 is detected.

Further, the stage 111 is provided so as to be able to move up and down with respect to the slider portion 116 of the transport structure 113.

For example, as shown in FIG. 11, a trapezoidal screw 142 rotationally driven by a motor 141 is provided in the slider portion 116 of the transport structure 113 in the vertical direction, and the trapezoidal screw 142 meshes with a nut 143 fixed to the stage 111. ..

With this configuration, the trapezoidal screw 142 rotates forward or reverse by rotationally driving the motor 141, and the stage 111 relatively moves up and down (up and down) with respect to the slider portion 116. Therefore, the fabric 400 held in the cassette 200 can be moved to a predetermined height with respect to the head 122.

Here, the fact that the height of the cassette 200 (the height of the fabric 400) has reached a predetermined height means that, for example, as shown in FIG. 12, the light emitting means 153A and the light receiving means 153B provided on the side plates 151 and 152 It is detected by a transmissive photo sensor (cassette height detecting means) composed of.

Further, the stage 111 is provided with a cassette presence / absence sensor 161 for detecting that the cassette 200 is mounted. As the cassette presence / absence sensor 161, for example, a push-type sensor that reacts by being pushed by the cassette 200 when the cassette 200 is mounted on the stage 111 may be used.

Next, the outline of the control unit of this printing apparatus will be described with reference to FIG. FIG. 13 is a block explanatory diagram of the control unit.

The control unit 700 includes a CPU 701 that controls the entire apparatus, a program that includes a program for causing the CPU 701 to execute control such as a printing operation including the control according to the present invention, a ROM 702 that stores other fixed data, and an image. It includes a main control unit 700A that also serves as a control means according to the present invention, including a RAM 703 that temporarily stores data and the like.

The control unit 700 includes a non-volatile memory (NVRAM) 704 for holding data even while the power of the device is cut off. Further, the control unit 700 includes an ASIC 705 that processes image processing that performs various signal processing for print data and other input / output signals for controlling the entire device.

The control unit 700 includes an I / F 706 for transmitting and receiving data and signals used when receiving print data from the external print data creation device 800.

The print data creation device 800 is a device that creates print data such as an image to be printed on the fabric 400, and is composed of an information processing device such as a personal computer.

The control unit 700 includes an I / O 707 for capturing detection signals of various sensors.

The control unit 700 includes a head drive control unit 708 that drives and controls the head 122.

The control unit 700 includes a motor drive unit 711 that drives the carriage movement motor 124 that moves the carriage 121 in the X direction, a motor drive unit 712 that drives the stage movement motor 134 that moves the stage 111 in the Y direction, and a stage 111. It includes a motor drive unit 713 that drives the stage elevating motor 141 that elevates and elevates in the Z direction.

The I / O 707 of the control unit 700 includes a detection signal such as a temperature / humidity sensor 560 that detects temperature and humidity as environmental conditions of the device, an output of a light receiving means 153B constituting the stage height detecting means, and a cassette presence / absence sensor 161. The detection signal, the detection output of the encoder sensor 135, and the detection signals of other sensors are input.

An operation panel 722 for inputting and displaying information necessary for this device is connected to the control unit 700.

The control unit 700 receives print data from the print data creation device 800, scans the carriage 121 in the X direction, intermittently moves the stage 111 in the Y direction, and heads according to the image data created from the print data. The drive control unit 708 drives the head 122 to discharge the liquid, and controls printing of a required image on the fabric 400 held in the cassette 200.

Next, the control of superposition printing by the printing apparatus will be described with reference to the flow chart of FIG. 14 and the schematic explanatory diagram of FIGS. 15 to 19.

With reference to FIG. 10, as described above, the user holds the fabric 400, which is the object to be printed, on the cassette 200, attaches the cassette 200 to the stage 111 of the apparatus main body 100 in a detachable manner, and then attaches the printing apparatus to the printing apparatus. A print instruction is given to 1.

When the start of printing is instructed with reference to FIG. 14 (step S101, hereinafter simply referred to as “S101”), the cassette 200 is mounted on the stage 111 by the cassette presence / absence sensor 161 (with cassette). ) Or not (S102).

At this time, if there is a cassette, the stage 111 is moved in the Y2 direction as shown in FIG. 15A, and the cassette 200 is moved below the head 122 as shown in FIG. 15B. Stop (S103).

Next, as shown in FIG. 16A, the stage 111 is raised in the Z1 direction to a predetermined height (S104), and then, as shown in FIG. 16B, the stage 111 is moved again in the Y2 direction. Then, the stage 111 is set to the standby position (S105).

The standby position is a movement start position at which the cassette 200 starts moving in the Y1 direction (opposite to the Y2 direction) in order to print on the fabric 400, and is also referred to as a writing position, an initial position, or the like. In the present embodiment, the attachment / detachment position and the standby position of the holding member (cassette 200) with respect to the receiving member (stage 111) have an opposite positional relationship in the reciprocating movement direction of the holding member. Therefore, the holding member mounted on the receiving member is moved from the attachment / detachment position to the printing operation start position (standby position), and then printing is started.

After that, as shown in FIG. 17A, the stage 111 is moved from the standby position in the Y1 direction to move the cassette 200 in the Y1 direction, and the liquid is discharged from the head 122 and held in the cassette 200. The first printing (preceding printing) is performed on the existing fabric 400 (S106).

Here, when the first printing is completed, the stage 111 is moved in the Y1 direction until the stage 111 reaches the attachment / detachment position for attaching / detaching the cassette 200 to / from the stage 111 as shown in FIG. 17B.

Then, it is determined whether or not the first printing is completed (S107), and whether or not there is a second printing (printing of the subsequent line) after the first printing is completed (S108).

At this time, if there is no second printing, the printing operation is finished, and the user removes the cassette 200 from the stage 111 and sets it in the heating device 500, so that the heating step is performed.

On the other hand, when there is a second print, as shown in FIG. 18A, the stage 111 is moved in the Y2 direction to return the cassette 200 to the standby position (S109).

Then, after returning the cassette 200 to the standby position and stopping the movement, it is determined whether or not the predetermined time has elapsed, and the cassette 200 is waited until the predetermined time elapses (S110). That is, the movement of the cassette 200, which is a holding member, is stopped for a predetermined time after the first printing and before the second printing.

Specifically, after the cassette 200 returns to the standby position, the motor drive unit 712 stops driving the stage moving motor 134. Then, when the counter 730 included in the control unit 700 starts counting and counts a predetermined number (count value) corresponding to a predetermined time stored in the ROM 72, the motor drive unit 712 drives the stage moving motor 134.

Further, the frequency counter measures the time after the cassette 200 returns to the standby position, and when the predetermined time stored in the ROM 72 is reached, the motor drive unit 712 drives the stage moving motor 134. You can also do it.

Then, after the predetermined time has elapsed, as shown in FIG. 18B, the stage 111 is moved in the Y1 direction to move the cassette 200 in the Y1 direction, and the liquid is discharged from the head 122 to discharge the cassette 200. The second printing (printing of the subsequent line) is performed on the fabric 400 held in (S111).

Here, when the second printing is completed, the stage 111 is moved in the Y1 direction until the stage 111 reaches the attachment / detachment position for attaching / detaching the cassette 200 to / from the stage 111 as shown in FIG.

It is determined whether or not the second printing is completed (S112), and when the second printing is completed, this process is terminated. Then, after the second printing is completed, the cassette 200 is removed from the stage 111, and the process proceeds to the heating step by the heating device 500 as described above.

As described above, the process of detachably attaching the cassette 200 holding the fabric 400 to the stage 111 in the printing apparatus main body 100 and the stage 111 at the standby position opposite to the attachment / detachment position of attaching / detaching the cassette 200 to / from the stage 111. A step of moving the stage 111 toward the attachment / detachment position side after moving the stage 111 to perform preceding printing, and a step of returning the stage 111 to the standby position after the preceding printing is completed and stopping the stage 111 at the standby position for a predetermined time. After a lapse of a predetermined time, the stage 111 is moved toward the attachment / detachment position side to perform the preceding printing, and the overlay printing is performed on the fabric 400.

Here, by making the data used for the preceding printing and the data used for the subsequent printing the same, it is possible to increase the density by superimposing and printing. Further, the data used for the preceding printing and the data used for the subsequent printing may be different from each other, such as the printing of the background processing and the printing of the target image.

In addition, although the example of performing printing twice is described here, it is also possible to perform superposition printing three times or more.

In this way, when overlay printing is performed on the print target by printing a plurality of times, the holding member that holds the print target is moved in advance before printing the subsequent line to be overlaid on the preceding print. By controlling the time stop, it is possible to start printing of the subsequent line after the vibration or the like caused by the movement of the holding member is attenuated, the misalignment of multiple printings is reduced, and the printing quality is improved.

That is, in the present embodiment, after the first printing is completed, the stage 111 is moved from the attachment / detachment position to the standby position, and then the second printing is performed. Since printing is not performed when the stage 111 is moved from the attachment / detachment position to the standby position, the stage 111 is moved at a speed faster than the movement speed of the stage 111 at the time of printing. Therefore, when the stage 111 returns to the standby position, the cassette 200 mounted on the stage 111 vibrates.

Therefore, after the stage 111 returns to the standby position, the movement of the stage 111 is stopped until the vibration of the cassette 200 is attenuated so that the print of the subsequent line does not shift in position with respect to the print of the preceding print.

In the present embodiment, the cloth 400 is not directly held by the stage 111, but is held by the cassette 200 detachably held by the stage 111. Since vibration is likely to occur in the cassette 200 due to the movement of the stage 111, it is particularly effective to stop the movement of the stage 111 for a predetermined time until the vibration is attenuated.

Next, the control of superposition printing of the printing apparatus according to the second embodiment of the present invention will be described with reference to the flow chart of FIG.

In the present embodiment, in steps S201 to S206, the same processing as in steps S101 to 106 of the first embodiment is performed to perform the first printing, and it is determined whether or not the first printing is completed (. S207).

Here, when the first printing (preceding printing) is completed, it is determined whether or not the state in which the cassette presence / absence sensor 161 has detected the cassette 200 continues (S209).

Here, when the state in which the cassette 200 is detected continues, the process proceeds to the determination (S209) of whether or not the second printing is performed, and if the second printing is performed, the first embodiment is described. Similarly, the operation proceeds to the second printing (printing of the subsequent line) (S210 to S213).

On the other hand, when the state in which the cassette 200 is detected does not continue, that is, when the cassette presence / absence sensor 161 detects that the cassette 200 does not exist even once, the printing operation is terminated as it is, and the second time. Does not shift to printing.

That is, if the cassette 200 is removed from the stage 111 even once after the first printing is completed, even if the cassette 200 is mounted on the stage 111 again, the cassette 200 and the stage 111 are the same as when the first printing is performed. There is a risk that the positional relationship will shift.

Therefore, when the state in which the cassette 200 is not present is detected even once, the process does not shift to the second printing.

Next, the control of superposition printing of the printing apparatus according to the third embodiment of the present invention will be described with reference to the flow chart of FIG.

In the first embodiment, after the first printing is completed, the stage 111 is moved in the Y2 direction, the cassette 200 is returned to the standby position, and then the second printing is performed. As a result, vibration is generated as the cassette 200 moves to the standby position. Therefore, in the first embodiment, the movement of the stage 111 is stopped for a predetermined time.

On the other hand, in the present embodiment, in steps S301 to S308, the same processing as in steps S101 to 108 of the first embodiment is performed to perform the first printing. Then, after the first printing is completed, it is determined whether or not there is a second printing. ((

Here, when there is a second printing, the cassette 200 is moved in the Y2 direction to perform the second printing (S309). Then, it is determined whether or not the second printing is completed (S310), and when the second printing is completed, the cassette 200 is moved in the Y1 direction and returned to the initial position (S311).

That is, unlike the first embodiment, the stage 111 is directed from the attachment / detachment position to the standby position without stopping the movement of the cassette 200 for a predetermined time after the first printing and before the second printing. The second printing is performed while intermittently moving in the Y2 direction (see FIG. 18A).

Here, since the stage 111 is intermittently moved during the printing operation, the cassette 200 is in a state in which substantially no vibration is generated when the cassette 200 is moved to the attachment / detachment position after the first printing is completed. .. Therefore, in order to attenuate the vibration, the second printing can be performed without stopping the movement of the cassette 200 for a predetermined time.

Since the cassette 200 has been moved to the standby position at the end of the second printing, the cassette 200 is moved to the detachable position after the second printing is completed.

In the above embodiment, the case where the print target is a cloth such as a T-shirt is described, but the present invention is similarly applied to the case where the print target is a medium including the cloth, for example. Can be applied.
