Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above printing apparatus, depending on the type of cloth, when ink is applied, the cloth may shrink. Then, the position where the ink discharged thereafter adheres to the cloth may deviate from the desired position of the cloth.

[0005] An object of the present invention is to provide a platen and a printing apparatus capable of reducing the possibility that the position where the discharged ink adheres to the fabric deviates from the desired position of the fabric.

Means for Solving the Problems

[0006] The platen according to the first aspect of the present invention is a platen that supports a fabric on which ink is discharged by an inkjet head, and includes a plurality of protruding portions that protrude upward from the upper surface of the platen, and the tip of the protruding portion has a shape that hooks the fluff or fibers of the fabric.

[0007] In the first embodiment, the tip of the protruding part of the platen catches the fluff or fibers of the fabric, thus reducing the amount of shrinkage of the fabric due to the ink. Therefore, the possibility that the position where the ejected ink adheres to the fabric will be off from the desired position on the fabric can be reduced.

[0008] The platen extends in a first direction perpendicular to the vertical direction, and in a second direction perpendicular to the vertical direction and the first direction, and the plurality of protrusions may project outward from the upper surface of the platen upward and in the first and second directions.

[0009] In this case, the platen can reduce the amount of shrinkage of the fabric that tends to shrink inward towards the platen due to the protrusions.

[0010] The multiple protrusions may, on their outer side, protrude in the removal direction in which the fabric is removed from the platen.

[0011] When the user removes the fabric from the platen in the removal direction, the protruding part extends upward and in the removal direction, thus reducing the likelihood of the fabric being removed getting caught on the protruding part.

[0012] The platen supports the garment as the fabric, and a positioning portion for positioning the collar of the garment is provided at one end of the platen in the first direction, and the plurality of protrusions may protrude upward and toward the one end.

[0013] When a user removes clothing from the platen towards one end, the protrusion extends upward and toward the end, reducing the likelihood of the clothing being removed getting caught on the protrusion.

[0014] Multiple of the aforementioned protrusions may be provided across the entire surface of the upper surface.

[0015] In this case, the platen can reduce the amount of fabric shrinkage caused by the ink compared to a case where a protrusion is provided on part of the upper surface.

[0016] The printing apparatus according to the second aspect of the present invention includes an inkjet head that discharges ink onto a fabric, and a platen that supports the fabric. The platen includes a plurality of protruding portions that protrude upward from the upper surface, and the tip of the protruding portion has a shape that catches the fluff or fibers of the fabric.

[0017] The printing apparatus of the second aspect can achieve the same effects as the first aspect.

[0018] The inkjet head may include a base inkjet head that discharges base ink, and a color inkjet head that discharges color ink on top of the base ink.

[0019] Since the printing apparatus reduces the amount of shrinkage of the fabric by the base ink, it can reduce the possibility that the position where the discharged color ink adheres to the fabric is shifted from the position where the base ink adheres to the fabric.

MODE FOR CARRYING OUT THE INVENTION

[0021] The printer 1 and the platen 5 according to an embodiment of the present invention will be described with reference to the drawings. The printer 1 shown in FIG. 1 is an inkjet printer that performs printing by ejecting ink onto a fabric as a printing medium. The fabric is, for example, cloth, felt, etc., and in this embodiment, it is a T-shirt 90. The upper, lower, lower left, upper right, lower right, and upper left in FIG. 1 are the upper, lower, front, rear, right, and left of the printer 1 and the platen 5, respectively. In this embodiment, the mechanical elements in the drawings indicate the actual scale.

[0022]

[0023] The conveyance unit 6 is provided below the opening 21 and conveys the platen support member 3 in the front-rear direction. In detail, the transport unit 6 includes a pair of rails 12 as shown in Figure 2. The pair of rails 12 are aligned horizontally and extend in the front-to-back direction. The platen support member 3 is located above the transport unit 6 and is supported by the pair of rails 12. A sub-scanning motor (not shown) is provided at the bottom of the platen support member 3. The platen support member 3 can move in the front-to-back direction along the pair of rails 12 by being driven by the sub-scanning motor.

[0024] The platen 5 is positioned inside the opening 21 when viewed from the front. The platen 5 is supported by the platen support member 3 and moves in the front-rear direction between the printing position and the attachment / detachment position together with the platen support member 3. That is, the front-rear direction of the printer 1 is the sub-scanning direction. The printing position is the position where the platen 5 faces the heads 100 and 200, which will be described later, inside the housing 2. The attachment / detachment position is in front of the printing position and is the position shown in Figure 1. When the platen 5 is in the attachment / detachment position, the platen support member 3 and the platen 5 reach the front end of the pair of rails 12, and the platen support member 3 is positioned outside the housing 2. Details of the structure of the platen 5 will be described later. A T-shirt 90 is placed on the top surface of the platen 5 as an example of fabric.

[0025] As shown in Figure 2, the printer 1 is housed in a housing 2 as shown in Figure 1 and includes rails 11, a guide shaft 9, a carriage 20, and heads 100 and 200. The rails 11 are located at the upper rear of the printer 1 and extend in the left-right direction. The guide shaft 9 is located in front of the rails 11 and extends in the left-right direction. The carriage 20 is located between the rails 11 and the guide shaft 9 in the front-rear direction and is supported by the rails 11 and the guide shaft 9. A main scanning motor 19 is located to the right of the right end of the guide shaft 9. The carriage 20 can move left-right along the rails 11 and the guide shaft 9 by the drive of the main scanning motor 19.

[0026] Heads 100 and 200 are positioned front to back and mounted on carriage 20, and move laterally together with carriage 20. Head 100 is positioned behind head 200. Print heads 100 and 200 each have nozzles (not shown) at the bottom, and ink is ejected downwards from these nozzles.

[0027] Printer 1 can print color images on a printing medium using five inks: white, black, yellow, cyan, and magenta. Hereinafter, the white ink will be referred to as "white ink," and the four inks of black, cyan, yellow, and magenta will be collectively referred to as "color inks." When referring to both white ink and color inks collectively, or when neither is specified, the term "ink" will be used. White ink is used in printing to represent the white areas of an image or as a base for other colored inks. Color inks are ejected onto the white ink base and used to print color images.

[0028] Printhead 100 ejects white ink from its nozzles. Printhead 200 ejects colored ink from its nozzles.

[0029] Referring to Figures 3 and 4, the detailed structure of the platen 5 will be described. The platen 5 comprises a plate 50, an adhesive material 8, and a sheet 7. The plate 50 extends in the front-to-back and left-to-right directions, and in plan view it is a rectangle that is longer in the front-to-back direction, and is made of, for example, metal. The adhesive material 8 and the sheet 7 are laminated on the upper surface of the plate 50 from the bottom up. The adhesive material 8 is, for example, double-sided tape, and fixes the plate 50 and the sheet 7. As shown in Figure 3, the sheet 7 covers the entire upper surface of the plate 50 in plan view. Therefore, in plan view the platen 5 has the same shape as the plate 50, and is a rectangle in plan view with its long side in the front-to-back direction and its short side in the left-to-right direction.

[0030] As shown in Figure 4, multiple protrusions 71 are provided on the entire upper surface 70 of the sheet 7, arranged at predetermined intervals. The protrusions 71 project upward and forward from the upper surface 70 of the sheet 7, for example. The multiple protrusions 71 are, for example, the hook-shaped napped side members of a hook-and-loop fastener. The protrusions 71 taper from the base to the tip. The height of the protrusions 71 is, for example, 1.7 mm. As shown in Figure 6, the tip catches the fibers 92 of the T-shirt 90 when the T-shirt 90 is set on the platen 5. Also, since the protrusions 71 project upward and forward from the upper surface 70 of the sheet 7, when the T-shirt 90 is pulled forward and removed from the platen 5, snagging between the removed T-shirt 90 and the protrusions 71 is reduced.

[0031] As shown in Figure 3, a positioning portion 51 is provided at the front end 53 of the platen 5. The positioning portion 51 is a rod-shaped member that extends forward from both the left and right sides toward the center in a plan view. The rear end of the positioning portion 51 is fastened to the plate 50 by fastening members (not shown) through a plurality of holes 52 that penetrate vertically through the right front and left front parts of the plate 50.

[0032] Referring to Figures 1, 2, 5, and 6, the overview of printing in printer 1 will be explained. First, the user operates the input unit 46 to move the platen 5 to the attachment / detachment position shown in Figure 1. The user holds the hem of the T-shirt 90 with the collar 91 facing forward and the length in the front-to-back direction, and moves the T-shirt 90 backward from the hem side so as to cover the platen 5. At this time, the T-shirt 90 is moved while separated upward from the sheet 7.

[0033] As shown in Figure 5, the collar 91 contacts the positioning part 51, completing the positioning of the T-shirt 90 relative to the platen 5. The user places the T-shirt 90 on the sheet 7 and sets it on the platen 5. At this time, as shown in Figure 6, the tip of the protrusion 71 hooks the fibers 92 of the T-shirt 90 set on the platen 5. The user operates the input unit 46 to move the platen 5 with the T-shirt 90 set on it from the attachment / detachment position to the printing position.

[0034] Printer 1 scans the carriage 20 from side to side, ejecting white ink from head 100 and color ink from head 200. Once the ink ejection for one scan is complete, Printer 1 moves the platen 5 forward and again scans the carriage 20 from side to side, ejecting ink from heads 100 and 200. Since head 100 is located behind head 200, the color ink is ejected on top of the white ink. In other words, the white ink is used as a base for the color ink.

[0035] If the white ink ejected from the head 100 as a base coat adheres to the T-shirt 90, the white ink may cause the T-shirt 90 to shrink. If the T-shirt 90 shrinks, the position where the subsequent color ink adheres to the T-shirt 90 may be shifted from the position where the white ink adhered. The platen 5 has a protruding tip 71 that catches the fibers 92 of the T-shirt 90, thus reducing the amount of shrinkage caused by the white ink. Therefore, the possibility of the color ink adhering to the T-shirt 90 being misaligned from the position where the white ink is applied to the T-shirt 90 is reduced, and the desired printing result can be obtained.

[0036] Once the printer 1 has finished printing on the T-shirt 90, it moves the platen 5 to the attachment / detachment position shown in Figure 1. The user holds the collar 91 and pulls the T-shirt 90 forward to remove it from the platen 5. At this time, the T-shirt 90 slides on the sheet 7. Since the protrusions 71 protrude upward and forward from the upper surface 70 of the sheet 7, the T-shirt 90 sliding on the sheet 7 is removed from the platen 5 without getting caught on the protrusions 71.

[0037] As described above, the platen 5 comprises a board 50, an adhesive material 8, and a sheet 7. The adhesive material 8 and the sheet 7 are stacked on the upper surface of the board 50 in order from the bottom. The sheet 7 has a plurality of protrusions 71 arranged at predetermined intervals. The protrusions 71 protrude upward and forward from the upper surface 70 of the sheet 7. As shown in Figure 6, the tips of the protrusions 71 catch the fibers 92 of the T-shirt 90 set on the platen 5. This reduces the amount of shrinkage of the T-shirt 90 due to the ink. Therefore, the platen 5 can reduce the possibility that the position where the ejected ink adheres to the T-shirt 90 is off from the desired position on the T-shirt 90.

[0038] Multiple protrusions 71 are provided on the entire upper surface 70 of the sheet 7, arranged at predetermined intervals. In this case, the platen 5 can reduce the amount of shrinkage of the T-shirt 90 due to the ink compared to the case where the protrusions 71 are provided on only a part of the upper surface 70 of the sheet 7.

[0039] The platen 5 extends in the front-to-back and left-to-right directions, and the protrusion 71 protrudes upward and forward from the upper surface 70 of the sheet 7. When the user pulls the T-shirt 90 forward to remove it from the platen 5, the likelihood of the removed T-shirt 90 getting caught on the protrusion 71 is reduced.

[0040] A positioning portion 51 for positioning the collar 91 of the T-shirt 90 is provided at the front end 53 of the platen 5. The protruding portion 71 protrudes upward and forward. That is, the protruding portion 71 protrudes toward the front end 53 of the platen 5. This reduces the likelihood of the T-shirt 90 being caught on the protruding portion 71 when the user removes the T-shirt 90 from the platen 5 while holding the collar 91 and pulling the T-shirt 90 forward.

[0041] Printer 1 comprises print heads 100 and 200 that eject ink onto the T-shirt 90, and a platen 5 that supports the T-shirt 90. The tip of the protruding part 71 of the platen 5 catches the fibers 92 of the T-shirt 90, thus reducing the amount of shrinkage of the T-shirt 90 due to the ink. Therefore, printer 1 can reduce the possibility that the position where the ejected ink adheres to the T-shirt 90 is off from the desired position on the T-shirt 90.

[0042] Printer 1 has a head 100 that ejects white ink used as a base coat for printing, and a head 200 that ejects color ink on top of the white ink. Printer 1 reduces the amount of shrinkage of the T-shirt 90 due to the white ink, thus reducing the possibility that the position where the ejected color ink adheres to the T-shirt 90 will be different from the position where the white ink adheres to the fabric.

[0043] In the above embodiment, heads 100 and 200 correspond to the "inkjet heads" of the present invention. T-shirt 90 corresponds to the "fabric" or "clothing" of the present invention. Printer 1 corresponds to the "printing device" of the present invention. White ink corresponds to the "undercoat ink" of the present invention. Head 100 corresponds to the "undercoat inkjet head" of the present invention. Head 200 corresponds to the "color inkjet head" of the present invention. Plate 50 extends in a first direction and a second direction. An example of the first direction is the front-to-back direction, and an example of the second direction is the left-to-right direction. T-shirt 90 is pulled forward and removed from platen 5. An example of the removal direction is the forward direction. The upper surface 70 of the sheet 7 is an example of the "upper surface" of the present invention. The front end portion 53 of the platen 5 is an example of the "end portion" of the present invention.

[0044] The present invention can be modified in various ways from the above embodiments. The various modifications described below can be combined in any way, as long as they do not create contradictions. For example, the present invention can be applied to printers of a different type than the inkjet type described in the above embodiments.

[0045] In the above embodiment, a T-shirt 90 was used as an example of the fabric, but it is not limited to this. The fabric may be, for example, various shirts such as dress shirts, trousers, skirts, handkerchiefs, or the fabric itself. The fabric is not limited to woven fabrics, but may also be nonwoven fabrics such as felt. The tip of the protrusion 71 is not limited to the fibers of the fabric, but may also catch lint. When printing on nonwoven fabric, the tip of the protrusion 71 reduces the amount of shrinkage of the nonwoven fabric due to the ink. Therefore, the platen 5 can reduce the possibility that the position where the ejected ink adheres to the nonwoven fabric is shifted from the desired position on the nonwoven fabric.

[0046] In the above embodiment, the protrusion 71 protrudes upward and forward from the upper surface of the platen 5, but the direction in which the protrusion 71 protrudes is not limited to this. For example, as shown in Figure 7(A), the protrusion 71 protrudes upward. The protrusion 71 may also protrude radially outward from the center of the platen 5 in the front-to-back and left-to-right directions. The T-shirt 90 set on the platen 5 often has an image printed at a position corresponding to the center of the upper surface of the platen 5, and the ink tends to cause it to shrink inward in the front-to-back and left-to-right directions. Since the protrusion 71 protrudes in the directions described above, the tip of the protrusion 71 is likely to catch on the fluff or fibers of the fabric. Therefore, the platen 5 can reduce the amount of shrinkage of the T-shirt 90 that tends to shrink inward.

[0047] Furthermore, as shown in Figure 7(B), the protrusion 71 may not protrude from the center of the platen 5, but rather from the center of the rear end of the platen 5 in the left-right direction. In this case, the platen 5 can reduce the amount of shrinkage of the T-shirt 90, which tends to shrink inward, while also reducing snagging between the T-shirt 90, which is pulled forward and removed, and the protrusion 71.

[0048] The shape of the protrusion may be changed as appropriate. The shape of the protrusion should be such that its tip catches the fluff or fibers of the fabric. A shape in which the tip of the protrusion catches the fluff or fibers of the fabric is, for example, a shape in which the tip of the protrusion protrudes forward, backward, left, and right relative to the base. The protrusion is preferably a hook shape that extends upward from the base and protrudes from there in at least one of the directions forward, backward, left, and right, with a tip that is not curved but has corners. Such a shaped member is provided, for example, on the hook-shaped napped side of a hook fastener. The protrusion may also be a fibrous material found in clothing brushes, etc. The fibrous material as the protrusion only needs to protrude a few millimeters upward from the upper surface 70 of the sheet 7. The protrusion is preferably upward and protrudes in at least one of the directions forward, backward, left, and right, and among these, it is preferable that it protrudes forward, which is the direction in which the T-shirt 90 is removed.

[0049] As shown in Figure 8, the protrusion 72, which is the first modified example of the protrusion, is inverted J-shaped, and in a right-side view, it tapers from the base to the tip as it extends upward, then curves and extends forward. The protrusion 72 firmly holds the fluff or fibers of the fabric it catches, so even in the first modified example, the amount of shrinkage of the fabric due to the ink is reduced.

[0050] Furthermore, the second modified form of the protrusion, protrusion 73, is the so-called mushroom shape in hook-and-loop fasteners. After extending upward from the base, the upper end protrudes forward and backward as shown in Figure 9, and although not shown, it also protrudes to the left and right in the same way as forward and backward. The protrusion 73 has no directionality in the front-to-back and left-to-right directions. Like the protrusion 72, the protrusion 73 firmly holds the fluff or fibers of the fabric it catches, so the amount of fabric shrinkage due to ink is reduced in the second modified form as well. The protrusion 73 only needs to protrude forward and backward, and to the left and right.

[0051] Furthermore, as shown in Figure 10, the third modified example of the protrusion, the protrusion 74, has an inverted trapezoidal shape in a right-side view, with the tip wider than the base. Since the protrusion 74 has a simple structure that can catch the fluff or fibers of the fabric, the amount of fabric shrinkage caused by the ink is reduced even in this third modified example.

[0052] Furthermore, as shown in Figures 11 and 12, the fourth modified example of the protrusion, the protrusion 75, is needle-shaped and extends vertically. The platen 5 is provided with a plurality of grooves 76 that are recessed downward from the upper surface 54 of the plate 50 and extend in the front-rear and left-right directions. The protrusion 75 is provided at the intersection of the groove 76 extending in the front-rear direction and the groove 76 extending in the left-right direction. The tip of the protrusion 75 protrudes above the upper surface 54 of the plate 50. The tip of the protrusion 75 pierces and hooks the fabric placed on the platen 5. Therefore, even in the fourth modified example, the amount of shrinkage of the fabric due to ink is reduced. In the fourth modified example, the upper surface 54 of the plate 50 is an example of the "upper surface" of the present invention.

[0053] The shape of the protrusions may be such that the tips catch on the fluff or fibers of the fabric, as shown in the modified example above. Sheet 7 may be provided with a combination of protrusions of different shapes. For example, sheet 7 may have protrusions 71 and protrusions 73 arranged alternately in the left-right direction.

[0054] The protrusions 71-75 may be provided only on a portion of the upper surface of the platen 5. For example, the protrusions 71-75 may be provided only on the upper surface of the platen 5 corresponding to a position on the T-shirt 90 that is frequently printed (for example, the center of the T-shirt 90).

[0055] In the above embodiment, the platen 5 and plate 50 are rectangular in shape, with the front-to-back direction being the longitudinal direction and the left-to-right direction being the short direction in a plan view, but are not limited to this. The platen 5 and plate 50 may be rectangular in shape, with the left-to-right direction being the longitudinal direction and the front-to-back direction being the short direction in a plan view, or they may be square. When the T-shirt 90 is removed to the left or right, or when a positioning part 51 is provided at the right end or left end of the platen 5, an example of the first direction is the left-to-right direction, and an example of the second direction is the front-to-back direction.

[0056] In the above embodiment, the adhesive material 8 was exemplified as double-sided tape, but it is not limited to this. For example, an adhesive such as glue may be used. Also, the board 50 and the sheet 7 may be fixed by means other than the adhesive material 8. For example, the sheet 7 may be fixed by sandwiching the sheet 7 between a frame portion that covers the edge of the upper surface of the board 50 and the board 50. Alternatively, the sheet 7 may be fixed to the upper surface of the board 50 by both the adhesive material 8 and the frame portion.

[0057] The configuration of the positioning section 51 may be changed as appropriate. For example, a marker for positioning the collar 91 of the T-shirt 90 may be provided on the front end of the upper surface of the plate 50, and this may be used as the positioning section 51. Also, the positioning section 51 may not be provided on the platen 5.

[0058] For example, printer 1 may be configured to move the platen 5 in the main scanning direction without moving the heads 100 and 200. In other words, printer 1 only needs to move the heads 100 and 200 and the platen 5 relative to each other.

[0059] The carriage 20 only needs to be equipped with at least one of the print heads 100 or 200. For example, the carriage 20 may be equipped with only the print head 200. The ink ejected by print heads 100 and 200 may be changed as appropriate.

[0060] In the above embodiment, the platen 5 moves in the front-rear direction between the attachment / detachment position and the printing position, but the positions to which the platen 5 moves are not limited to these. For example, the platen 5 may move to the mounting position, the printing position, and the removal position. The mounting position is the same position as the attachment / detachment position shown in Figure 1. The removal position is a position behind the printing position. When the platen 5 is in the removal position, the platen support member 3 and the platen 5 reach the rear end of the pair of rails 12.

[0061] The user places the fabric on the platen 5, which is in the mounting position. The printer 1 moves the platen 5 to the printing position and prints on the fabric. Once printing is complete, the printer 1 moves the platen 5 to the removal position. The user pulls the fabric backward and removes it from the platen 5. In this modified example, since the fabric is pulled backward and removed from the platen 5, it is desirable that the protruding portion 71 protrudes upward and backward from the top surface of the platen 5.
