Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. Embodiments of the present invention will be described below with reference to the drawings. An image providing apparatus (image providing system) according to embodiment 1 of the present invention will be described with reference to fig. 1. Fig. 1 is a perspective view illustrating an example of a mode of use of the image forming apparatus.

The image forming apparatus (image forming system) 1000 includes a cartridge 200 as a printing object holding member, a printing apparatus 1, and a heating device 500. The cartridge 200 of the printing apparatus 1 is detachable, and an image is printed on a cloth 400 as a printing object (printing target member) held by the cartridge 200. The heating device 500 may house the cartridge 200, and heat the cloth 400 to fix the image after the cartridge 200 holding the cloth 400 is entirely housed.

The printing apparatus 1 and the heating apparatus 500 of the image forming apparatus 1000 are separated and independent from each other, and may be used in such a manner that the printing apparatus 1 and the heating apparatus 500 are arranged in parallel or the printing apparatus 1 and the heating apparatus 500 are superposed. In addition, the printing apparatus 1 and the heating apparatus 500 may be disposed at separate positions. By providing the printing apparatus 1 and the heating apparatus 500 in an overlapping manner, the installation area can be made efficient.

When an image is applied to the cloth 400 by the image application apparatus 1000, the cartridge 200 holding the cloth 400 is set (attached) to the printing apparatus 1, and the image is printed on the cloth 400 by the printing apparatus 1.

When the printing apparatus 1 finishes printing the image on the cloth 400, the cartridge 200 holding the cloth 400 is taken out from the printing apparatus 1. Then, the front door (front cover, front door) 502, which is a door member of the heating device 500, is opened, the cartridge 200, which is the printed cloth 400, is stored in the heating device 500, the front door 502 is closed, and the cloth 400 is heated by the heating device 500 together with the cartridge 200. By heating cloth 400, the image printed on cloth 400 is fixed to cloth 400.

Thus, the cartridge 200 serving as the printing object holding member can be shared by both the printing apparatus 1 and the heating apparatus 500. Accordingly, the printed cloth 400 can be set in the heating device 500 while being kept in the state during printing, and even if the cloth 400 is conveyed, the printed surface is not disturbed due to the wrinkles being deviated or partially overlapped, and the operability of applying an image to the cloth 400 is improved.

Next, an example of the printing apparatus will be described with reference to fig. 2 to 4. Fig. 2 is an external perspective explanatory view of the printing apparatus when the cartridge is pulled out, fig. 3 is an explanatory perspective view of the entire configuration of the mechanism section of the printing apparatus, and fig. 4 is an explanatory perspective view seen from a direction different from that of fig. 3.

The printing apparatus includes a stage 111 as a receiving member for detachably holding a cartridge 200 holding a cloth 400 therein and moving forward and backward, and a printing mechanism 112 for printing the cloth 400 (fig. 1) held in the cartridge 200 held by the stage 111, in an apparatus main body 100.

Here, the cloth 400 may be formed not only of one piece of cloth such as a handkerchief or a towel, but also of a part of products such as a T-shirt, a training clothes, and a handbag.

The stage 111 is provided on a conveyance structure 113 that is held to be movable in the arrow Y direction (conveyance direction) with respect to the apparatus main body 100.

Here, a conveyance guide member 115 is disposed in the direction of arrow Y in the bottom frame portion 114 of the apparatus main body 100, and the slide portion 116 of the conveyance structure 113 is held movably by the conveyance guide member 115.

The printing mechanism 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 held movably by a guide member 123 provided along the direction of the arrow X, and is reciprocated in the direction of the arrow X by a scanning mechanism portion such as a timing belt 125 by a drive motor 124. The head 122 performs image formation by ejecting ink onto the surface of the fabric using a liquid ejection head, but the present invention is not limited thereto.

In the printing apparatus 1, the cartridge 200 is mounted on the stage 111 in the apparatus main body 100 and held in a state where the cloth 400 is placed on the platen member 300 of the cartridge 200. Then, 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, a desired image is printed on the cloth 400.

In this case, the stage 111 may be raised and lowered in the direction of the arrow Z, and the stage 111 may be raised and lowered according to the thickness of the cloth 400, so that the distance between the cloth 400 and the head 122 may be adjusted to a predetermined distance. In addition, the printing mechanism 112 may be raised and lowered.

Next, an example of the cartridge will be described with reference to fig. 5 to 7. Fig. 5 is a perspective explanatory view of the cartridge, fig. 6 is a perspective explanatory view of a state in which an outer peripheral cover of the cartridge is opened, and fig. 7 is a schematic sectional explanatory view of a state in which the cartridge is different in a longitudinal direction along a section corresponding to a surface S1 of fig. 5.

The cartridge 200 includes a base member 201 and a platen member 300 that holds a printed portion of the cloth 400 in a flat state.

Platen member 300 includes a platen structure 302 and a heat insulating member 301 that constitutes a surface for holding cloth 400 in a flat state. The heat insulating member 301 has heat resistance to heating by the heating device 500.

Then, in the base member 201, one end portion of the outer peripheral cover member 202 is rotatably mounted on the hinge 203, and the outer peripheral cover member 202 is openable and closable in the arrow direction with respect to the base member 201.

The outer peripheral cover member 202 has a frame portion 202b having an opening portion 202a in a portion corresponding to the platen member 300, and presses the cloth 400 between the frame portion 202b and the flange portion 300a in the outer peripheral portion of the platen member 300.

The platen member 300 is supported by the support portions 311(311A, 311B) with respect to the base member 201, and a housing space 312 in which the remaining portion 400a of the cloth 400 can be housed is formed between the platen member 300 and the base member 201. The remaining portion 400a corresponds to two sleeves, a neckline, a hem, and the like when printing is performed on the front surface of a T-shirt, for example.

Here, the platen member 300 is formed to be detachable and replaceable from the base member 201. This makes it possible to prepare a plurality of platen members 300, set clothes on another platen member 300 in advance during a printing operation, and after printing and fixing are completed, it is possible to quickly start printing of the next cloth by merely replacing the platen member 300.

When the cloth 400 is placed on the cartridge 200, the outer circumferential cover member 202 is opened to place (hold) the cloth 400 on the platen member 300, as shown in fig. 6. At this time, as shown in fig. 7, the outer circumferential cover member 202 is closed as shown in fig. 5 in a state where an excess portion (remaining portion) 400a of the cloth 400 is accommodated in the accommodation space 312.

Then, when printing on the cloth 400, the cartridge 200 on which the cloth 400 is placed is mounted (set) on the stage 111 of the apparatus main body 100 of the printing apparatus 1.

In this way, since the cloth 400 to be printed can be placed on the platen member 300 in a state where the entire cartridge 200 is removed from the apparatus main body 100, the placing operation of the cloth 400 can be easily performed on the platen member 300.

Such a cartridge 200 is placed (moved) into the heating device 500 as it is with the cloth 400 after the printing is completed by the printing device 1, and heats and fixes the cloth 400 on which the image is printed.

In the cartridge 200, the platen member 300 is supported by the base member 201 by the

support portions

311A and 311B. The support portion 311A is disposed on the front side in the direction of insertion and removal of the cartridge 200 into and from the printing apparatus 1, and the support portion 311B is disposed on the rear side in the direction of insertion and removal of the cartridge 200 into and from the printing apparatus 1. Two

support portions

311A and 311B are disposed in a direction perpendicular to the direction in which the cartridge 200 is inserted into and removed from the printing apparatus 1.

The support portion 311A includes a hollow support portion 231A on the base member 201 side, a hollow support portion 331A on the platen member 300 side movably fitted to the hollow support portion 231A, and a compression spring 313A disposed between the hollow support portion 231A and the hollow support portion 331A.

The support portion 311B includes a hollow support portion 231B on the base member 201 side, a hollow support portion 331B on the platen member 300 side movably fitted to the hollow support portion 231B, and a compression spring 313B disposed between the hollow support portion 231B and the hollow support portion 331B.

Here, the hollow support portion 331A of the support portion 311A on the platen member 300 side is configured to be separable from the platen member 300, and the front side of the platen member 300 can be separated from the hollow support portion 331A and lifted up.

Specifically, as shown in fig. 7(B), the support portion 311B fixes the hollow support portion 331B and the platen member 300, and the hollow support portion 231 is not fixed to the base member 201 and is held rotatably when the front side of the platen member 300 is lifted.

The hollow support portion 331A of the support portion 311A is not fixed to the platen member 300, the hollow support portion 231A is fixed to the base member 201, and the platen member 300 is configured to be placed on the support portion 311A.

This raises the front side of the platen member 300, separates it from the support portion 311A, and forms a gap (clearance)340 between it and the support portion 311A through which a printing target can pass.

Further, the platen member 300 is supported to be displaceable with respect to the base member 201.

Further, a locking claw member 204a is provided on the outer peripheral cover member 202. The locking claw member 204a is disposed on the side opposite to the side where the outer peripheral cover member 202 is held by the hinge 203 so as to be openable and closable with respect to the base member 201.

On the other hand, the base member 201 is provided with a locking claw holding member 204b that holds the locking claw member 204a or releases the holding of the locking claw member 204 a.

The lock mechanism 204 is constituted by the lock claw members 204a and the lock claw holding members 204b, and the height of the outer peripheral cover member 202 covering the peripheral portion of the platen member 300 with respect to the base member 201 is restricted.

With this configuration, when the thickness of cloth 400 changes, platen member 300 falls against the restoring force of spring 313, and then the distance from base member 201 changes, so that it is possible to cope with cloths 400 having different thicknesses.

Then, since the platen member 300 is always pressed against the outer peripheral cover member 202 with a constant force, the cloth 400 is less likely to be displaced even when the cartridge 200 is conveyed.

In addition, even when the thickness of cloth 400 is changed, since a gap between platen member 300 and outer peripheral cover member 202 is secured by lowering platen member 300, the height of outer peripheral cover member 202 with respect to base member 201 does not change even if the thickness of cloth 400 is changed.

Next, the operation of placing the cylindrical member in the cartridge will be described with reference to fig. 8 to 12. Fig. 8 is a front explanatory view of a main part of a fabric to be printed, and fig. 9 to 12 are sectional explanatory views for explaining a process when a cuff of the fabric is set on a platen member of a cartridge.

The fabric 400 to be printed is a T-shirt, and a sleeve 401, which is a cylindrical portion (cylindrical member), has a sewing stitch (stitch leg) 402 on the back surface of the sleeve 401, in the structure of the shirt. When the front and back surfaces of the sleeve 401 are placed on the platen member 300, the portion of the sewing stitch 402 becomes thick, and the portion of the sewing stitch 402 becomes a convex portion and protrudes from the printing surface, and wrinkles occur or interference with the printing mechanism occurs, and thus good printing may not be performed. Further, the front body 403 also has a sewing stitch 402 at an end portion thereof.

When this cartridge 200 is used, the sleeve 401 is fitted into the platen member 300 while avoiding the sewing stitches 402 of the sleeve 401, and only one surface of the sleeve 401 is placed on the platen member 300.

Specifically, as shown in fig. 9, in a state where the outer peripheral cover member 202 is opened, as shown in fig. 10, the platen member 300 is separated from the support portion 311A by lifting the near side of the platen member 300, and a gap 340 capable of passing through the sleeve portion 401 on the side of the sewing stitch 402 is formed between the hollow support portion 331A and the platen member 300.

Then, as shown in fig. 10, the sleeve portion 401 is fitted into the outer peripheral surface of the platen member 300, and as shown in fig. 11, the sewing needle surface 402 of the sleeve portion 401 is placed on the back surface side of the platen member 300 so that the sewing needle surface 402 is not exposed from the surface of the platen member 300.

Then, as shown in fig. 12, by closing the outer circumferential cover member 202, the sleeve 401 can be placed on the platen member 300 in a flat state while suppressing the occurrence of wrinkles, and the print quality can be improved.

Next, an example of the heating device will be described with reference to fig. 13 to 17. Fig. 13 is an external perspective explanatory view of the heating device, and fig. 14 is a perspective explanatory view of a state in which a front door of the heating device is opened. Fig. 15 is a schematic cross-sectional explanatory view along the longitudinal direction of the heating device (the direction in which the cartridge moves in and out), and fig. 16 is a schematic cross-sectional explanatory view along the longitudinal direction (the direction in which the cartridge is pulled out and pushed in) for explaining the mode of use of the heating device. Fig. 17 is a schematic cross-sectional view of the heating device in the short-side direction (direction perpendicular to the cartridge drawing-in and drawing-out direction).

The heating device 500 includes a device main body 501, and a front door (front cover) 502 provided on the front side of the device main body 501 as a door member that opens and closes an opening 511 of the device main body 501 into and out of which the cartridge 200 is drawn and pushed.

The front door 502 is openable and closable in the arrow direction shown in fig. 15, and is provided to be openable and closable and laid down as shown in fig. 14. By opening the front door 502, the cartridge 200 holding the cloth 400 as a heating target (also a printing target) can be pulled out and pushed into the apparatus main body 501 through the opening 511.

A receiving member (table) 503 capable of holding the cartridge 200 in a state of being pulled out and pushed in is disposed inside the apparatus main body 501 (inside the apparatus main body), and the cartridge 200 is a printing object holding member for detachably holding the cloth 400.

The receiving member 503 may be configured by a member that holds the cartridge 200 detachably, or a table that simply holds the cartridge 200 by placing it thereon, as in the stage 111 of the printing apparatus 1. Here, the table is constituted.

Then, a heating mechanism 504 for heating the cloth 400 held in the cartridge 200 is disposed above the receiving member 503.

The heating mechanism 504 includes a heater 542 as a heat generating mechanism facing the cloth 400 held in the cartridge 200, and a heat insulating member 543 for insulating heat from the side of the heater 542 opposite to the receiving member 503. A space 506 is provided between the heat insulating member 543 and the inner wall surface of the apparatus main body 501.

The facing surfaces of the heater 542 and the receiving member 503 are configured to be substantially parallel to the exposed surface of the cloth 400, and the cloth 400 is held by the cartridge 200 provided in the apparatus main body 501. The heating range (heating region) of the heater 542 is set to a length L1 in the longitudinal direction and a width W1 in the lateral direction.

Further, a planar member made of a material having excellent thermal conductivity such as aluminum may be provided on the receiving member 503 side of the heater 542, and the surface temperature may be made substantially uniform by heat generation of the heater 542. Thus, heating can be performed at almost the same temperature in the plane regardless of the heating position of heater 542.

The heating mechanism 504 is held by a holding member 508 on the opening 511 side of the apparatus main body 501. In the present embodiment, below the holding member 508 is an insertion opening 512 of the insertion cartridge 200. However, when the upper end of the opening 511 of the apparatus main body 501 is located below the lower end of the holding member 508, the opening 511 is the insertion opening 512.

The receiving member 503 is held by a vertical movement mechanism (position switching mechanism) 507, and is arranged to be relatively movable in three stages in the vertical direction (direction in which the relative distance changes) with respect to the heating mechanism 504.

By moving the operating lever 558 of the vertical movement mechanism 507 in the neutral position, the arrow a direction, and the arrow B direction in fig. 13, the receiving member 503 can be moved vertically.

Here, the relative position of the receiving member 503 with respect to the heating mechanism 504 is a standby position (1 st position) shown in fig. 15 when the operation lever 558 is located at the neutral position, a non-contact heating position (2 nd position) shown in fig. 16(a) when the operation lever 558 is rotationally operated in the arrow a direction, and a contact heating position (3 rd position) shown in fig. 16(B) when the operation lever 558 is rotationally operated in the arrow B direction.

The standby position of fig. 15 is a position when the cartridge 200 is pulled out and pushed in. The non-contact heating position in fig. 16(a) is a heating position when the cloth 400 is heated by the heating mechanism 504 in a non-contact manner. The contact heating position in fig. 16 b is a heating position (pressing position) where the cloth 400 is heated by contacting the heating mechanism 504.

Referring to fig. 13, the operation panel 520 is provided with a self-illuminated warm-up start key (button) 521a for instructing the start of the warm-up operation, a stop key 521b for instructing the stop of the warm-up operation, a warm-up display unit 521c for displaying the warm-up operation, and the like.

In the above embodiment, the support portion on the front side in the drawing/pushing direction of the cartridge (printing target holding member) with respect to the printing apparatus is described as an example of a configuration that can be separated from the platen member, but the present invention is not limited thereto. For example, the support portion on the back side of the cartridge (printing object holding member) in the drawing/pushing direction with respect to the printing apparatus may be configured to be separable from the platen member. In the case where a plurality of support portions are arranged in a direction perpendicular to the pull-in and push-out direction of the cartridge (printing object holding member) with respect to the printing apparatus, the plurality of support portions on one side or the other side may be configured to be separable from the platen member in the direction perpendicular to the pull-in and push-out direction.

In the above embodiment, the case where the printing object is a cloth was described, but the present invention is not limited to this. The present invention can be similarly applied to a case where printing is performed by placing a printing object other than a cloth on a platen member.
