## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The entire disclosure of Japanese Patent Application No. 2012-098463, filed Apr. 24, 2012 is expressly incorporated by reference herein.
BACKGROUND
1. Technical Field
The present invention relates to a tray which is used when setting a fabric, that is, a material to be printed, an ink jet textile printing apparatus including the tray, and a method of manufacturing printed matter.
2. Related Art
In the related art, an ink jet textile printing apparatus has been developed and widely used, which prints a desired image by ejecting ink of each color from an ink ejecting head towards the surface of a material to be printed on, such as a T-shirt or a like fabric.
When placing a target material (on which printing is performed) with respect to such an ink jet textile printing apparatus, a tray is used. The target material is supported by a transporting unit which can perform transporting of the target material toward a textile printing execution region in which an ink ejecting head is present.
In the tray, a long shaft fixed positioning portion is provided with respect to a support unit of the transporting unit so as to protrude to the side of the support unit as disclosed in JP-A-2004-284305 which is described below.
However, as described above, when a long shaft fixed positioning portion is provided in the tray, it is difficult to horizontally place the tray because the tray is disturbed by the long shaft portion even when attempting to place the tray on a flat table by detaching the tray from the support unit since the long shaft portion is in the way.
In addition, it is actually difficult to perform setting work even when trying to set a fabric in the tray which is placed on the table in such an unstable inclined posture. Accordingly, in the related art, it took a long time to set the fabric, since a setting work of resetting a new fabric each time the printing finishes in a state in which the tray is fixed to the support unit has been performed in a setting area of the ink jet textile printing apparatus.

A tray 3A according to a first embodiment (hereinafter, described as trays 3A, 3B, and 3C, respectively when classifying each of embodiments 1 to 3) includes a main body 65 which has a setting surface 23 on which the material to be printed T is set. As a first protrusion portion, the tray 3A also includes a positioning pin 67 is provided in a protruding manner at a mounting surface 24, which is the opposite side to the setting surface 23 of the main body 65. The positioning pin is used when mounting the main body 65 to the support unit 31. The tray 3A also includes a leg portion 71 which is provided in a protruding manner on the mounting surface 24 of the main body 65, and which leg portion 71 has a protruding dimension that is longer than the positioning pin 67.
That is, the tray 3A includes the leg portion 71 which horizontally supports the main body 65 in a state in which a tip end 67a of the positioning pin 67 does not come into contact with a planar portion 69 (FIG. 6, such as a table), when the main body 65 is horizontally placed on the planar portion 69.
In addition, the tray 3A is detachably provided with respect to the support unit 31 of the apparatus main body 2.
In addition, as illustrated in FIG. 3, according to the embodiment, the main body 65 is a member which is formed in a rectangular flat shape of which corner portions are processed to be rounded. The peripheral four sides of the main body 65 are formed with an edge portion 7 which is formed to be thinner than a main body portion 5 at the center, and is formed in an outer flange shape which is projected outward in the horizontal direction.
In addition, a top face of the main body portion 5 of the main body 65 is set as the setting surface 23 where the second surface 11 of the material to be printed T is supported from below, and the lower surface of the main body portion 5 is set as the mounting surface 24 on which the attachment unit 47 (which will be described later) is mounted.
In addition, according to the embodiment, it is configured such that the edge portion 7 of the main body 65 is attached with a fitted-in frame 25 as illustrated in FIG. 3, which fixes the material to be printed T on the main body 65 in a state in which the material to be printed is positioned at a predetermined set position.
A squared window portion 57 (towards which the main body portion 5 of the main body 65 is positioned) is formed in the frame 25. That is, the frame 25 is configured by a member having a rectangular frame shape of which peripheral four sides in which the window portion 57 is formed at the center are surrounded by four frame elements 26 having L-shaped cross sections.
In addition, in the four frame elements 26, a step portion 59 is provided having an inner flange shape which faces the top face of the edge portion 7 of the above described main body 65. Further, a side plate portion 61 is provided which faces the side surface of the edge portion 7 of the above described main body 65.
In addition, two holes 68 for attaching the positioning pin 67 (which will be described later) are formed at the center of the main body 65. In the vicinity of two sides of the main body 65 on left and right in the width direction B, attaching holes 77 (which are used when attaching the leg portion unit 70 which will be described later) are formed by 4 on the left and right sides by being slid in line by two.
The leg portion unit 70 in FIG. 3 is in a state in which the unit is not yet attached to the main body 65.
The positioning pin 67 which is provided with respect to the mounting surface 24 of the main body 65 is a shaft member of which the tip end 67a has a circular cross-sectional shape which is processed in a spherical shape so as to be rounded, and of which a diameter is thick.
In addition, the outer flange portion 67b is formed in the middle of the positioning pin 67. A portion (on the base end side from the outer flange portion 67b) is embedded in the hole 68 which is formed at the center of the main body 65. In addition, the outer flange portion 67b may not be provided.
The leg portion 71 is configured by a flat member having a triangular shape when viewed from the side, and is located at the inner side of one end portion 66 of the main body 65. In addition, the leg portion 71 has an inclined surface 71a which retreats toward the inside from the end portion 66 of the main body 65. That is, the outer surface of the leg portion 71 becomes the inclined surface 71a which is able to guide a movement of the material to be printed T which is mounted from the end portion 66.
As illustrated in FIGS. 4 and 6, since the inclined surfaces 71a are provided at antero-posterior sides in the tray movement direction, it is possible to obtain an effect of reducing influence of air when moving, compared to a structure which vertically extends in the vertical direction.
The leg portion 71 is provided between the end portion 66 and the positioning pin 67 in the tray moving direction (transport direction A).
In addition, according to the embodiment, a square bar-shaped member is formed toward the inside from the inner inclined surface of the leg portion 71. The square bar-shaped member is configured so as to function as a grip portion 73 which is used when a user carries the tray 3A by taking the portion using hands.
In addition, as illustrated in FIG. 6, in a state in which the tray 3A is horizontally placed on the planar portion 69 (such as a table), the space S (where hands of a worker enter) is formed between the grip portion 73 and the planar portion 69.
In addition, in the state in which the tray 3A to which the fixing frame 25 is attached is horizontally placed on the planar portion 69, a base 73a of the grip portion 73 is located at the planar portion 69 side (the lower side) of a base 25a of the fixing frame 25.
In addition, it is configured such that the base 73a side of the grip portion 73 is positioned on the planar portion 69 side rather than the base 25a side of the frame 25 in a state in which the tray 3A (which is attached to the frame 25) is horizontally placed on the planar portion 69.
Further, a screw aperture is provided on the top face side of the leg portion unit 70 in which the leg portion 71 and the grip portion 73 are integrally formed.
In addition, the screw aperture is screwed with a fixing screw 79 which is inserted from the upper part of the attaching hole 77 which is formed in the vicinity of two sides on the left and right of the above described main body 65 in the width direction B, and four sets of the leg portion unit 70 are attached to a predetermined position of the mounting surface 24 of the main body 65 in bilateral symmetry.
In addition, an attaching position (with respect to the mounting surface 24 of the main body 65 of the leg portion unit 70) can be appropriately changed to attaching modes which are illustrated in FIGS. 7A to 7C.
FIG. 7A illustrates an attaching mode in which, in a state in which the tray 3A is mounted on the support unit 31, a leg portion unit 70A (which is arranged at the front side as a side to which a worker access), and a leg portion unit 70B (which is arranged at the rear side) are connected in the tray 3A.
FIG. 7B illustrates an attaching mode in which the leg portion unit 70A (which is arranged at the front side), and a leg portion unit 70B (which is arranged at the rear side) are separated. Here, “connected” means that at least a part of an end portion of the leg portion unit 70A on the rear side comes into contact with at least a part of an end portion of the leg portion unit 70B on the front side.
In addition, FIG. 7C illustrates an attaching mode in which a part of the leg portion unit 70A (which is arranged at the front side) is overlapped with a part of the leg portion unit 70B (which is arranged at the rear side). It is possible to appropriately select these attaching modes by switching thereof according to a size or the like of the main body 65 to be used.
In FIG. 7, it is preferable that the positioning pin 67 and the grip portion 73 are arranged by being overlapped with each other in the width direction. In addition, at least a part thereof may be overlapped with each other. In this manner, it is possible to reduce a concern that user's hands, or a printed matter may come into contact with the positioning pin 67. The grip portion 73 functions as a bulwark.
It is also possible to use two leg portions on one side with respect to the plurality of trays of which sizes are different. In this case, it is preferable that the length of the leg portion unit 70 (one leg portion 71 and one grip portion 73) in the front-back direction (transport direction A) as the first direction is the length of a minimum-sized tray or less, and the shortest distance between positioning pin 67 and the end portion 66 in a maximum-sized tray, or more.
Due to this, it is easy to use the leg portion unit, since the leg portion unit 70 (one leg portion 71 and one grip portion 73) does not protrude from the minimum-sized tray (first tray) in the first direction. In addition, it is possible to reduce a concern that the user's hands, or the printed matter may come into contact with the positioning pin 67, since the positioning pin 67 is in a state of being covered with the leg portion unit 70 (one leg portion 71 and one grip portion 73).
In addition, the shortest distance is the shortest distance between the positioning pin 67 and the end portion 66 which is closest from each positioning pin 67 in the front-back direction (transport direction A). The distance may be a distance from the center of the positioning pin 67, or may be a distance from a portion which is the farthest from a point of the end portion 66 as a target between the positioning pin 67 and the outer flange portion 67b. 
A shape of the main body 65 of the tray 3 is not limited to the rectangular shape which is illustrated in the embodiment. It is also possible to apply the embodiment of the present invention to a pentagon, a hexagon, a heptagon, an octagon, or the like.
In addition, as illustrated in FIG. 5, the attachment unit 47 (which is used for attaching the tray 3 to the support unit 31 of the apparatus main body 2) includes an attaching plate 49. The attaching plate 49 has a hole 48 to be fitted with the positioning pin 67 of the tray 3. The attaching plate 49 further has a positioning shaft portion 51 which protrudes to the support unit 31 side of the apparatus main body 2 from a center of the attaching plate 49.
In addition, in the illustrated embodiment, four positioning pins 53 (three positioning pin 53A and one positioning pin 53B) in total are provided at positions in the periphery of the positioning shaft portion 51, and in the vicinity of a central front end. The attachment unit 47 is attached to the support unit 31 through the connection mechanism 33 using these four positioning pins 53, and the positioning shaft portion 51.
The attaching plate 49 is a rectangular planar member which is smaller than the main body 65 of the tray 3, and for example, is formed by appropriately folding a metal flat plate material.
The attaching plate 49 is attached with bearing members 81A and 81B for supporting two positioning pins 67A and 67B (two positioning pins 67 are classified by being attached with A and B) which protrude from the mounting surface 24 of the tray 3A, on the top face side on which the tray 3A is mounted. Inclined surfaces 81a and 81a (which become narrower in the downward direction) and guide insertion of the positioning pins 67A and 67B are formed at an opening portion on the insertion side of these bearing members 81A and 81B (two bearing members 81 are classified by being associated with suffixes A and B). In addition, the holes 48 and 48 are formed in a penetrating state from the lower end portion of these inclined surfaces 81a and 81a to the base of the attaching plate 49.
The above described positioning shaft portion 51 (which has a long circular cross-sectional shape, and of which the diameter is thick) is provided (so as to be protruded on the support unit 31 side) at the center of the base of the attaching plate 49 which is attached to the support unit 31.
A base end portion of the positioning shaft portion 51 is supported by the bearing member 83 (FIG. 5) which is accommodated in the attaching plate 49. The positioning shaft portion is attached to the attaching plate 49 by tightening a fixing bolt which is inserted from a hole 55 which is formed at the center of the attaching plate 49 on the top face side.
In addition, the three positioning pins 53A which are provided in the periphery of the positioning shaft portion 51 are short round rod-shaped members of which diameters are smaller than that of the positioning shaft portion 51, and a tip end 53a of the positioning pin 53A is processed to be spherical. On the other hand, the positioning pin 53B (which is close to the front end of the attaching plate 49) is a long round rod-shaped member of which a diameter is small, and a tip end 53b is processed to be chamfered.
Subsequently, operations of the tray 3A will be described according to a flow of operations from a setting operation of the material to be printed T which is performed using the above described tray 3A and the attachment unit 47 to mounting of the tray 3A with respect to the apparatus main body 2.
1. When Performing Setting Operation
The setting operation of the material to be printed T in the tray 3A is performed by placing the tray 3A on a planar portion 69 (FIG. 6) on a table, or the like. According to the embodiment, in this case, the above described attachment unit 47 is provided with the positioning shaft portion 51, thus excluding the long positioning shaft portion 51 from the configuration of the tray 3A. In addition, the tray 3A is provided with the above described leg portion unit 70. In this manner, it is possible to place the tray 3A on the planar portion 69 in a state in which the main body 65 is horizontally supported.
Accordingly, it is not necessary to set the material to be printed T in an unstable posture in which the main body 65 is inclined, and it is possible to set the material to be printed T in a stable posture in which the main body 65 is horizontally supported. Accordingly, it is possible to perform an efficient setting work of the material to be printed T, and to reduce a labor of a worker.
In addition, the material to be printed T (which is set with respect to the setting surface 23 of the tray 3A in this manner is positioned at a predetermined setting position), is inserted between the step portion 59 and the side plate portion 61 of the frame 25 and the edge portion 7 of the tray 3A by inserting the frame 25 from above, the frame 25 being further fixed to the tray 3A.
In addition, prior to the ink jet printing, it is possible to finish setting work of a plurality of pieces of materials to be printed T in advance. Thus may be done by preparing a plurality of trays 3A (which are configured as above). In such a case, the setting work of the material to be printed T, and a fixing work using the frame 25 are repeatedly performed by the number of necessary pieces.
In addition, according to the embodiment, it is possible to treat an end portion of the material to be printed T (which protrudes to the outside of the setting surface 23 when performing the setting work which is performed in the periphery of the leg portion 71) without being hindered by the presence of the leg portion 71. This is because the leg portion 71 is provided inside the end edge portion 66 of the tray 3A, and because the inclined surface 71a is formed at the outside of the leg portion 71.
In addition, when the material to be printed T (such as a T-shirt, or the like) is set so as to be put on the main body 65 in a state in which the tray 3A is arranged at the support unit 31 of the ink jet textile printing apparatus, a concern that the material to be printed may be caught by the leg portion 71 when causing the material to be printed to be put on is reduced, and workability is improved.
In addition, according to the embodiment, it is possible to correspond to main bodies 65 with various sizes using leg portion units 70 having the same configuration. This may be done by attaching the leg portion unit 70 by changing an attaching position with respect to trays with different sizes. Accordingly, by communizing the leg portion unit 70, it is possible to reduce cost of components, and a problem of false mounting of the leg portion unit 70 (which is caused when providing the plurality of leg portion units 70) is reduced.
2. When Carrying
When the tray 3A in which the material to be printed T is set in this manner is used as is, the tray 3A is carried to the support unit 31 of the ink jet textile printing apparatus 1. When the tray is temporarily stored in a storing space or the like, the tray is carried to the storing space.
When the tray 3A is carried, hands are put into the space S which is formed between the grip portions 73 and 73 on the left and right sides and the planar portion 69 (FIG. 6) from the outside, and the grip portions 73 and 73 on the left and right sides are raised upward by being grabbed.
In addition, according to the embodiment, at this time, since it is configured such that the base 73a side of the grip portion 73 is located at the planar portion 69 side rather than the base 25a of the frame 25, a concern that only the frame 25 may be carelessly held up by hands which act first on the base 25a of the frame 25 is reduced.
In addition, by providing such a grip portion 73, it is possible to easily carry the tray 3A, and to carry the tray 3A to a desired position by reliably holding the tray 3A.
3. Mounting onto Support Unit
The tray 3A (which is carried to the support unit 31 of the ink jet textile printing apparatus 1 in this manner) is mounted on the attachment unit 47 (which is attached to the support unit 31) in the following manner.
The tray 3A (which is carried to the support unit 31 which is present in a setting area by being held at the grip portion 73) causes the two positioning pins 67 and 67 (which protrude from the mounting surface 24 of the main body 65) to be fitted into the fitting holes 48 and 48, by being inserted, which are formed on the attaching plate 49 while being guided to the inclined surfaces 81a and 81a of the bearing members 81 and 81 which are attached to the top face of the attaching plate 49 of the attachment unit 47.
In addition, positioning of the tray 3A with respect to the attachment unit 47 is performed when the two positioning pins 67 and 67 are fitted into the two fitting holes 48 and 48, and a fixing state of the tray 3A with respect to the attachment unit 47 is settled due to the own weight of the tray 3A, since the tray 3A itself has a corresponding weight.
Accordingly, the fixing state is also maintained with respect to a movement of transport unit 17 of the ink jet textile printing apparatus 1, and ink jet printing by the printing unit 19 is performed.
Second Embodiment
Refer to FIGS. 8 and 9
In a tray 3B according to a second embodiment, only a part of configurations in a main body 65 is different from the tray 3A according to the first embodiment, and other configurations than that are the same as those in the first embodiment.
Accordingly, here, descriptions of the same configurations as those in the first embodiment are omitted. A configuration of the tray 3B according to the second embodiment, a form of use, and the operation which are executed when using the tray 3B will be described mainly based on the configuration of the main body 65 which is different from that in the first embodiment.
That is, according to the embodiment, as illustrated in FIG. 8, four concave portions 87 (at which a leg portion 71 of another tray 3B which is accumulated on the tray 3B is arranged) are formed corresponding to the number of leg portions 71 and positions on a setting surface 23 of the main body 65. Here, it is preferable that the shape of the concave portion 87 is formed in a shallow and smooth concave plane so as not to decrease the same smoothness as the setting surface 23 of the main body 65 (in FIG. 8, concave portion 87 is largely illustrated for easy understanding).
The concave portion 87 has the depth in which a tip end portion 71b of the leg portion 71 can be accommodated, and is formed by a concave portion which has the same shape as the tip end portion 71b of the leg portion 71, and is slightly larger than the tip end portion 71b. 
It is preferable that the depth of the concave portion 87 has the thickness of the main body 65 or less, since the concave portion is formed on the surface of the tray. In addition, it is preferable that the depth of the concave portion 87 is 1⁄2 of the thickness of the main body 65 or less, when considering deterioration in strength of the main body 65. In addition, since there is a concern that both of the tip end portion 71b of the leg portion 71 and the concave portion 87 may be sharpened due to a contact with each other (depending on the material), the concave portion may be a through hole which penetrates the base of the main body 65. It is preferable to form the concave portions 87 on the outer side of a printing region.
In addition, when using the tray 3B configured in this manner, since the tip end portion 71b of the leg portion 71 of the upper tray 3B is arranged at the concave portion 87 which is formed on the setting surface 23 of the lower tray 3B when the plurality of sets of tray 3B are accumulated as illustrated in FIG. 9, the accumulated state of the tray 3B becomes strong, and position aberration of the tray 3B in each step, or a collapse of the tray 3B is suppressed.
In addition, a storing efficiency of the tray 3B is improved compared to a structure in which accumulation is not possible, by accumulating the plurality of sets of tray 3B. Here, the storing efficiency means the number of trays per unit area.
Third Embodiment
Refer to FIG. 10
In a tray 3C according to a third embodiment, configurations of a main body 65, a leg portion 71C (reference numeral C is attached in order to distinguish from that in first embodiment), and a grip portion 73C (reference numeral C is attached in order to distinguish from that in first embodiment) are different from the tray 3A according to the first embodiment, and other configurations than those are the same as those in the first embodiment.
Accordingly, here, descriptions of the same configurations as those in the first embodiment are omitted. A configuration of the tray 3B according to the third embodiment, and operation thereof will be described mainly based on the configurations of the main body 65, the leg portion 71C, and the grip portion 73C which are different from those in the first embodiment.
That is, according to the embodiment, as illustrated in FIG. 10, the grip portion 73C and the leg portion 71C are configured by separate members. The main body 65 of the tray 3 is provided with a long hole 89 which can adjust an attaching position of the leg portion 71C in a predetermined range in the front-back direction instead of the attaching hole 77 which is provided according to the first embodiment.
Specifically, the leg portion 71C is configured by a planar member which is triangular when viewed from the side, and screw apertures are formed on the top face of the leg portion 71C by two.
The grip portion 73C is configured by a handle-like member in which a rod member (which is bent in a gate shape) is protruded toward the lower part from the mounting surface 24 of the main body 65, and is bent toward the outside on the side.
In addition, the main body 65 is formed with an attaching hole 91 (for attaching the grip portion 73C to the mounting surface 24 of the main body 65), and the leg portion 71C and the grip portion 73C are attached to a predetermined position on the mounting surface 24 of the main body 65 using a fixed screw 79.
In addition, the same effect as that in the tray 3A according to the first embodiment is exerted when the tray 3C which is configured in this manner is used. Also, according to the embodiment, it is possible to adjust an attaching position of the leg portion 71C at a position where a worker comfortably works, and the carrying of the tray 3C becomes easy, since the grip portion 73C becomes easy to grab.
Other Embodiments
The tray, the ink jet textile printing apparatus, and the manufacturing method of a printed matter according to the embodiment of the invention are basically configured as described above. However, as a matter of course, it is also possible to perform partial changes in the configuration, omissions, or the like, without departing from the scope of the invention.
For example, the shape, the material, the numbers, and the like of the leg portion 71 are not limited to the configurations which are illustrated in the embodiments 1 to 3, and it is possible to adopt various configurations. It is possible to adopt a leg portion 71 of a rectangular block shape, a circular truncated cone shape, a truncated pyramid shape, a columnar shape, a prismatic shape, or the like. In addition, as a material, it is also possible to adopt various materials such as synthetic resin, wood, a gummy elastic material.
In addition, the number of leg portions 71 is not limited to four, and may be three, or it is possible to provide five or more leg portions. The attaching position of the leg portion 71 is not limited to a peripheral edge portion of the mounting surface 24 of the main body 65, and it is also possible to provide the leg portion 71 inside the peripheral edge portion.
(1) Number of Leg Portion
For example, the number of leg portions may be adjusted according to a tray size. Specifically, the leg portion is assumed to be increased according to an increase in size of the tray, for example, two for small size, three for medium size, four for large size. When the leg portions are two, a lower end of the leg portion is formed in a planar surface shape so as to be stably raised even with two leg portions. When the tray size increases, the weight of the tray increases according thereto. In such a case, when the tray is neglected for a long time, there is a concern that the tray may be deformed due to its own weight. Therefore, it is possible to suppress the deformation of the tray by increasing the leg portion according to the tray size.
When the tray size is small, there is a little concern of deforming of the tray compared to a large tray, since the small tray has a short distance between a center point and an end portion. Accordingly, a small leg portion is provided to a small tray in order to reduce cost, and to prevent an increase in weight.
(2) Attaching Position of Leg Portion
In addition, in the tray, the deformation of the tray due to its own weight becomes serious at the four corner portions, which are distant from the center point. Accordingly, by arranging the leg portion at a position which is closer to the corner, it is possible to suppress the deformation of the tray.
(3) Attaching Method of Leg Portion
According to the above described embodiments, the leg portion 71 is provided in a protruding manner in the same direction as the positioning pin 67 from the mounting surface 24 of the main body 65. However, for example, there may be a configuration in which the leg portion 71 protrudes from the side surface of the main body 65, that is, the leg portion 71 is screwed to the side surface of the main body 65, and is protruded in the same direction as the positioning pin 67 from the side surface of the main body 65.
In addition, as a material of the main body 65, for example, it is possible to use a transparent synthetic resin flat plate material such as an acrylic plate. However, it is also possible to use an opaque synthetic resin flat material, wood, aluminum flat plate material, or the like. In addition, it is also possible to configure the main body 65 using a composite material in which a strengthened frame of aluminum, or stainless steel is provided in the periphery of the acrylic synthetic resin flat plate, or the like.
In addition, when the weight of the tray 3 is light, it is also possible to provide a locking unit of a screw type, or a clamp type which fixes the tray 3 on the attachment unit 47 after placing the tray 3 on the attachment unit 47, in order to prevent the tray 3 in the middle of printing from being lifted.
In addition, according to the embodiments, a fabric is used as the material to be printed, however, paper or wood, a medium such as a film, or the like may be used.
