In another aspect of the present disclosure, there is provided an image applier that includes a cloth holder, a printer, and the heating apparatus. The cloth holder holds a cloth. The printer prints an image on the cloth held by the cloth holder. The heating apparatus heats the cloth on which the image has been printed by the printer, with the cloth being held by the cloth holder.
In still another aspect of the present disclosure, there is provided an image applying method that includes holding a cloth on a cloth holder, printing an image on the cloth with the cloth being held by the cloth holder, holding the cloth holder with the cloth being held by the cloth holder, and heating the cloth with the cloth holder being held on the receiver of the heating apparatus.
A more complete appreciation of the disclosure and many of the attendant advantages and features thereof can be readily obtained and understood from the following detailed description with reference to the accompanying drawings, wherein:
The accompanying drawings are intended to depict embodiments of the present disclosure and should not be interpreted to limit the scope thereof. The accompanying drawings are not to be considered as drawn to scale unless explicitly noted.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In describing embodiments illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the disclosure of this specification is not intended to be limited to the specific terminology so selected and it is to be understood that each specific element includes all technical equivalents that have a similar function, operate in a similar manner, and achieve a similar result.
Hereinafter, embodiments of the present disclosure are described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and redundant description thereof are simplified or omitted as appropriate.
Below, embodiments of the present disclosure are described with reference to the accompanying drawings. An image applier (image applying system) according to a first embodiment of the present disclosure is described with reference to
The image applier (image applying system) 1000 of
The printer 1 and the heating apparatus 500 of the image applier 1000 are separate bodies and can be used in a form in which the printer 1 and the heating apparatus 500 are arranged side by side or in a form in which the printer 1 and the heating apparatus 500 are stacked one on the other. In some embodiments, the printer 1 may be spaced apart from the heating apparatus 500. If the printer 1 is stacked on the heating apparatus 500 or the heating apparatus 500 is stacked on the printer 1, the image applier 1000 decreases the area occupied by the printer 1 and the heating apparatus 500.
In order to cause the image applier 1000 to apply an image to the cloth 400, the user sets or attaches the cassette 200 to a stage 111 inside the printer 1 so that the printer 1 prints the image on the cloth 400.
When the printer 1 finishes printing the image on the cloth 400, the user removes the cassette 200 mounting the cloth 400 from the printer 1. The user opens a front door (front cover) 502 that is a door member of the heating apparatus 500 and accommodates the cassette 200 holding the printed cloth 400 in the heating apparatus 500. The user then closes the front door 502 and heats the cloth 400 together with the cassette 200 by the heating apparatus 500. As the heating apparatus 500 heats the cloth 400, the heating apparatus 500 fixes the image printed on the cloth 400.
In other words, the step of holding the cloth 400, to which an image is to be applied, in the cassette 200 being a cloth holder, the step of printing the image on the cloth 400 with the cloth 400 held on the cassette 200, and the step of holding the cassette 200 holding the cloth 400 in a receiver 503 (see
Thus, the cassette 200 serving as a cloth holder is used in both the printer 1 and the heating apparatus 500. Such a configuration allows the cassette 200 to be set in the heating apparatus 500 while holding the printed cloth 400 in the same state as when the image is printed on the printed cloth 400. Even if the user carries the cassette 200 mounting the cloth 400, the cloth 400 is immune from creasing or partial overlapping that might degrade the print face of the cloth 400, enhancing the operability for the user in applying the image to the cloth 400.
Next, an example of the printer is described with reference to
The printer 1 includes the stage 111 and a printing device 112 in a body 100. The stage 111 is a receiving member to move back and forth and removably hold the cassette 200, which is a cloth holder to hold the cloth 400 also being a member to be printed. The printing device 112 performs printing on the cloth 400 held by the cassette 200, which is held by the stage 111.
The cloth 400 is, for example, a piece of cloth, such as a handkerchief or towel, a fabric manufactured as clothing, such as a T-shirt or a sweatshirt, or a fabric used as a part of a product, such as a tote bag.
The stage 111 is disposed to be movable in a direction (feed direction, which is also referred to as Y direction) indicated by arrow Y in
The printing device 112 includes a carriage 121 that moves in a direction (main scanning direction, which is also referred to as X direction) indicated by arrow X with respect to the stage 111. A liquid discharge head is mounted on the carriage 121. That is, the printer 1 is an apparatus for forming an image by an inkjet recording system. Note that, in some embodiments, the printer 1 may employ any other recording system.
In the printer 1, with the cloth 400 set on a platen 300 of the cassette 200, the cassette 200 is attached and held on the stage 111 in the body 100. As the movement of the stage 111 in the Y direction and the reciprocal movement of the printing device 112 (the carriage 121) in the X direction are repeated, a desired image is printed on the cloth 400.
Here, the stage 111 can also be raised and lowered in a direction (Z direction) indicated by arrow Z in
In the printing operation, printing may be performed while moving the stage 111, on which the cassette 200 is attached, from the position in
Next, an outline of the cassette is described with reference also to
The cassette 200 includes a base 201 and a platen 300 that holds a portion of the cloth 400 to be printed in a flat state.
As illustrated in
One end portion of an outer peripheral cover member 202 is rotatably attached to the base 201 by a hinge 203. The outer peripheral cover member 202 is openable and closable along a direction indicated by arrow R1 relative to the base 201.
The outer peripheral cover member 202 includes a frame portion 202b that has an opening portion 202a at a portion corresponding to the platen 300. The outer peripheral cover member 202 holds the cloth 400 between the frame portion 202b and a flange portion 300a being an outer peripheral portion of the platen 300.
The platen 300 is supported by supports 311 with respect to the base 201. An accommodation chamber 312 is formed between the platen 300 and the base 201 to accommodate a surplus portion 400a of the cloth 400. For example, when an image is printed on the front surface of a T-shirt, the surplus portion 400a may be a sleeve, a neck, a hem, or the like of the T-shirt.
Here, the platen 300 is detachable from the base 201 to be exchangeable with a new one. Such a configuration allows a plurality of platens 300 to be prepared so that, during printing operation, a cloth is wound around one platen 300 and another cloth is wound around another platen 300. Thus, printing of the next cloth can be promptly started by simply replacing the platen 300 after printing and fixing.
When setting the cloth 400 in the cassette 200, as illustrated in
When printing is performed on the cloth 400, the cassette 200 on which the cloth 400 is set is attached (set) on the stage 111 of the body 100 of the printer 1.
As described above, with the cassette 200 entirely detached from the body 100, the user can set the cloth being a print target on the platen 300, thus facilitating setting operation of the cloth 400 to the platen 300.
After the printer 1 finishes printing, the cassette 200 is set (transferred) to the heating apparatus 500 while holding the cloth 400. The cloth 400 on which the image is printed is heated and fixed by the heating apparatus 500.
In the cassette 200, the support 311 supporting the platen 300 includes a hollow columnar portion 231 on the base 201 side, a hollow columnar portion 331 on the platen 300 side, and a compression spring 313 between the hollow columnar portion 231 and the hollow columnar portion 331. The hollow columnar portion 331 is movably fitted to the hollow columnar portion 231.
Accordingly, the platen 300 is supported displaceably with respect to the base 201 being the base member.
The outer peripheral cover member 202 includes lock claws 204a. Each of the lock claws 204a is disposed on a first side of the outer peripheral cover member 202 opposite to a second side of the outer peripheral cover member 202 that is held by the hinge 203 to be openable and closable with respect to the base 201.
On the other hand, the base 201 includes lock claw holders 204b to hold the lock claws 204a or releases holding of the lock claws 204a.
The lock claws 204a and the lock claw holders 204b constitute at least part of locks 204 to regulate the height of the outer peripheral cover member 202 covering the peripheral portion of the platen 300 with respect to the base 201.
With such a structure, when the thickness of the cloth 400 changes, the platen 300 descends against the restoring force of the compression spring 313, the distance to the base 201 changes, and the cloth 400 having a different thickness can also be handled.
The platen 300 is continuously pressed against the outer peripheral cover member 202 with a constant force. Accordingly, even when the cassette 200 is carried, the cloth 400 is unlikely to shift.
Even when the thickness of the cloth 400 changes, the platen 300 descends to ensure a gap between the platen 300 and the outer peripheral cover member 202. Accordingly, even if the thickness of the cloth 400 is changed, the height of the outer peripheral cover member 202 with respect to the base 201 is maintained.
In other words, the height of the cloth 400 held by the platen 300 is determined based on the height of the outer peripheral cover member 202 with respect to the base 201.
Such a configuration can fix the lock position at which the outer peripheral cover member 202 is locked with respect to the base 201 by the locks 204, thus simplifying the configuration of the cassette 200. Since the lock position does not change, the user can readily operate the cassette 200.
Further, when the liquid discharge head is used for the printing device 112, image quality can be obtained with higher accuracy as the distance between the liquid discharge head and the surface of a print target to which liquid is applied is narrower.
In such a case, the platen 300 is held in a displaceable state and the peripheral portion of the platen 300 is pressed against the outer peripheral cover member 202. Accordingly, even if the thickness of the cloth 400 changes, the height of the surface of the cloth 400 is regulated by the outer peripheral cover member 202, thus enhancing image quality.
For the configuration in which the platen 300 is displaceable, the supports 311 are preferably held on the peripheral portion side of the platen 300 to secure the parallelism of the surface of the platen 300 with respect to a moving plane of the liquid discharge head of the printing device 112. However, for such a configuration, the supports 311 might hamper the accommodation chamber 312 from accommodating the surplus portion 400a of the cloth 400.
By contrast, by defining the height of the surface of the cloth 400 held by the platen 300 with the height of the outer peripheral cover member 202, the supports 311 can be disposed inside the platen 300. Thus, the number of the supports 311 can also be reduced. Such a configuration can readily accommodate the surplus portion 400a of the cloth 400 in the accommodation chamber 312.
Next, the heating apparatus according to a first embodiment of the present disclosure is described with reference to
In the present embodiment, the heating apparatus 500 is a heating apparatus to heat the cloth and includes an apparatus body 501 and a front door (front cover) 502. The front door 502 is disposed on the front side of the apparatus body 501, to open and close an opening 511 through which the cassette 200 is inserted into and removed from the apparatus body 501.
The front door 502 is openable and closable in the directions indicated by arrow R2 in
A receiver (table) 503 is disposed inside the apparatus body 501. The receiver 503 holds the cassette 200 to be insertable or removable relative to the apparatus body 501. As described above, the cassette 200 serves as a cloth holder to removably hold the cloth 400 that is a heating target.
Similarly with the stage 111 of the printer 1 illustrated in
A heating device 504 is disposed above the receiver 503, to face the cloth 400 held by the cassette 200 and heat the cloth 400. The heating device 504 includes, for example, a heater that is a heat generator.
The surface of the heating device 504 facing the receiver 503 is configured to be positioned substantially parallel to an exposed surface of the cloth 400 held by the cassette 200 that is set on the apparatus body 501.
Note that a planar member made of a material having excellent heat conductivity, such as aluminum, is disposed on the side of the receiver 503 of the heating device 504, to heat the heating device 504 so that the surface temperature becomes substantially uniform by heat generation of the heating device 504. Such a configuration allows the cloth 400 to be heated at substantially the same temperature in the plane, regardless of the heating position.
The receiver 503 is held by a lift (position switching mechanism) 507 that is an elevating device. The receiver 503 is relatively movable in three steps in the vertical direction (a direction in which the relative distance changes) with respect to the heating device 504.
The lift 507 includes an operation lever 558 being a position switching lever. When the operation lever 558 is moved in a direction indicated by arrow R3 or R4 in
Here, the relative positions of the receiver 503 with respect to the heating device 504 include a standby position (first position) illustrated in
The standby position illustrated in
As illustrated in
As illustrated in
Further, in the present embodiment, the heating device 504 is supported by the partition 603 via support members 604. In some embodiments, the heating device 504 may be held by the apparatus body 501.
In addition, side walls 501b on both sides of the apparatus body 501 include ventilation ports 605 as ventilation paths on lateral sides of the first space 601. For example, a fan may be disposed in the ventilation port 605.
In the heating apparatus 500, for example, the cassette 200 holding the cloth 400 to which liquid is applied is held by the receiver 503, and the heating device 504 generates heat to heat the cloth 400 in non-contact with the cloth 400. Note that the heating device 504 may generate heat to heat the cloth 400 in contact with the cloth 400.
Here, the heat generated from the heating device 504 heats the opposing cloth 400 and also heats the upper space 600 opposite to the cloth 400.
At this time, since the upper space 600 of the heating device 504 is partitioned into the first space 601 and the second space 602 by the partition 603, the temperature of the second space 602 on the side of the upper surface portion 501a of the apparatus body 501 does not immediately change due to convection while the temperature of the first space 601 on the side of the heating device 504 rises.
In such a case, some heat is transmitted to the second space 602 via the partition 603. However, since the second space 602 functions as a heat insulating portion, the temperature rise of the upper surface portion 501a of the apparatus body 501 is suppressed.
Further, using a heat reflecting material (heat shield) such as aluminum or the like as the partition 603 can further reduce the transfer of heat to the second space 602.
Further, since the ventilation ports 605 communicating with the outside of the apparatus body 501 is disposed at lateral sides of the first space 601, for example, air of the first space 601 whose temperature has been increased by the heating device 504 is exchanged with the outside air by natural convection.
As a result, the temperature rise of the first space 601 immediately above the heating device 504 is suppressed, and the temperature rise of the upper surface portion 501a and the second space 602 on the side of the upper surface portion 501a is also suppressed.
In addition, the ventilation ports 605 are disposed to face the first space 601 immediately above the heating device 504. Such a configuration can suppress the temperature rise of the receiver 503 side of the heating device 504 (the cloth 400 side at heating) while suppressing the temperature rise of the first space 601.
Thus, the temperature rise of the upper surface portion 501a of the apparatus body 501 can be suppressed without lowering the heating function.
Next, the heating apparatus according to a second embodiment of the present disclosure is described with reference to
In the present embodiment, ducts 611 connecting the first space 601 and the ventilation ports 605 are provided, and ventilation paths are formed by the ventilation ports 605 and the ducts 611. In the vertical direction, the duct 611 includes upper duct members 612 supporting the partition 603 and lower duct members 613 opposed to the upper duct members 612.
As described above, connecting the first space 601 to the ventilation ports 605 by the ducts 611 can effectively dissipate the heat of the first space 601 and further reduce a temperature fall of the receiver 503 side of the heating device 504 (the cloth 400 side at heating).
In such a case, a fan may be disposed at the ventilation port 605, and the duct 611 enhances the intake and exhaust efficiencies of the fan.
A part of the duct 611, for example, the lower duct member 613 may be formed of metal, for example, a sheet metal such as SECC (electro-galvanized steel plate). Such a configuration can more effectively release heat to the outside of the apparatus body by heat conduction of the sheet metal itself in addition to air convection, thus allowing more effective suppression of the temperature rise in the first space 601.
Next, the heating apparatus according to a third embodiment of the present disclosure is described with reference to
In the present embodiment, each of the ventilation ports 605 of the apparatus body 501 has a cross-sectional shape that widens from the inside to the outside of the apparatus body 501. The duct 611 also has a cross-sectional shape that widens from the first space 601 toward the ventilation port 605.
Thus, the cross-sectional shape of each of the ventilation port 605 and the duct 611 widening toward the outside can effectively dissipate the internal heat to the outside.
Next, the heating apparatus according to a fourth embodiment of the present disclosure is described with reference to
In the present embodiment, in the configuration of the second embodiment (or another embodiment), a protective cover 615 is disposed on the receiver 503 side of the lower duct member 613 of the duct 611.
Thus, when the lower duct member 613 is formed of, e.g., a sheet metal, the heat transmitted to the lower duct member 613 can be prevented from further leaking to the receiver 503 side. The protective cover 615 is preferably made of a resin material from the viewpoint of thermal conductivity.
Next, the heating apparatus according to a fifth embodiment of the present disclosure is described with reference to
In the present embodiment, in the configuration of the fourth embodiment (or another embodiment), a heat insulator 616 is disposed on the upper surface side of the second space 602, in this case, the inner surface side of the upper surface portion 501a of the apparatus body 501.
Such a configuration can suppress the temperature rise of the upper surface portion 501a of the apparatus body 501 even when the temperature of the second space 602 rises.
The shape of the “cloth holder” in an embodiment of the present disclosure is not limited to a box shape of, e.g., the cassette of the above-described embodiments if the cloth holder has a structure that can be attached to and detached from a printer, a heating apparatus, or a fixing device. For example, the cloth holder may be a single plate-shaped platen member that is insertable into the printer and the heating apparatus.
Further, for further enhancement of the workability, the cloth holder with a cloth (e.g., T-shirt) already set may be used to obviate the step of an operator's setting the cloth on a tray every time for printing. In such a case, the cloth holder is collected after use and the cloth holder with another cloth already set is supplied.
Alternatively, to attain similar advantages, a platen member, which is attachable to and detachable from the cloth holder, with a cloth (e.g., T-shirt) already set may be used. In the case of using the platen member with the already-set cloth, the platen member with the already-set cloth is directly mounted on the cloth holder. After completion of printing and fixing, the platen member is removed from the cloth holder. Then, another platen member with an already-set cloth is mounted on the cloth holder, and printing and fixing are performed on the already-set cloth. In such a case, the platen member is collected after use, and the platen member with another cloth already set is supplied.
Such a configuration can obviate an operator's setting of a cloth (e.g., T-shirt) every time, facilitate continuous processing of a plurality of clothes, and automate continuous processing of a plurality of clothes.
In the above-described embodiments, the case in which the cloth is a T-shirt or the like is described. However, the present disclosure can be similarly applied to a case in which an object to be heated is a medium including, for example, a cloth. In such a case, the cloth used in the above-described embodiments serves as the medium. Furthermore, the present disclosure can also be applied to a heating apparatus that heats heating target members, such as foods, other than clothes and media.
Numerous additional modifications and variations are possible in light of the above teachings. It is therefore to be understood that, within the scope of the above teachings, embodiments of the present disclosure may be practiced otherwise than as specifically described herein. With some embodiments having thus been described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the scope of the present disclosure and appended claims, and all such modifications are intended to be included within the scope of the present disclosure and appended claims.
