JP 2004-276319 A JP 2007-31888 A

  However, in Patent Document 1, when setting the clothing (T-shirt) on the platen, the one end of the platen is set so as to protrude from the clothing (T-shirt), and the other end of the platen is taken from the clothing (T-shirt). The configuration was set so as not to protrude. In other words, the alignment is performed only on one end side of the platen and not on the other end side. Therefore, there is a possibility that the clothes (T-shirt) may be inclined with respect to the platen.

  Moreover, in patent document 2, since it was the structure which inserts the said T-shirt extending | stretching tool in T-shirt, it was difficult to match | combine the center of a T-shirt with the center of a T-shirt extending | stretching tool. In addition, in the state where the T-shirt stretcher is expanded to the left and right after the insertion, the T-shirt stretching tool may be uneven, and the T-shirt surface may be uneven.

  The present invention has been made in view of such a situation, and its problem is to determine the state of the surface of the fabric in addition to the position and inclination of the fabric with respect to the support portion when the fabric is placed on the support portion. It is to provide an inkjet printing apparatus that takes into consideration.

  In order to achieve the above object, an inkjet printing apparatus according to a first aspect of the present invention includes a support unit that supports a fabric, and a discharge unit that discharges ink to the fabric supported by the support unit. The support portion is configured to include a reference portion for alignment that protrudes at least partially outside an outline of the supported fabric for alignment of the fabric with respect to the support portion.

According to this aspect, when the fabric is set on the support portion, a relative positional relationship between the support portion and the fabric can be determined by the positioning reference portion. That is, the position of the fabric can be easily aligned with the center of the support portion as compared with the case where the alignment reference portion is not provided in the support portion. In addition, it is possible to reduce the possibility that the fabric is inclined with respect to the support portion. As a result, it is possible to execute printing at a desired position and orientation on the fabric. Here, “textile printing” refers to printing and dyeing a pattern on a fabric with ink.
For example, textile printing can be performed on the center of the fabric.
The alignment reference portion may be provided with a mark.
Moreover, since it is only necessary to provide the alignment reference portion, the support portion can be provided smoothly, and the surface state of the fabric can be made flat.

According to a second aspect of the present invention, in the first aspect, the alignment reference portion protrudes outward from both sides of the fabric in at least one direction.
According to this aspect, in addition to the same effect as the first aspect, the user can adjust the amount of protrusion of the alignment reference portion that protrudes from both sides of the fabric to be substantially the same. Thereby, the position of the fabric can be easily aligned with the center in the one direction.

According to a third aspect of the present invention, in the first or second aspect, the shape of the edge of the support portion is a shape having an edge parallel to the outline of the fabric in a range of more than half. To do.
According to this aspect, in addition to the same effects as those of the first or second aspect, the user adjusts the amount of protrusion of the alignment reference portion that protrudes from the fabric in the parallel portion to make it substantially equal. Can do. Thereby, compared with the case where it is the structure which does not have a parallel edge, a fabric can be set to the position of the center of the said support part still more easily.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the support portion includes a reference portion that supports a central portion inside the outline of the fabric, and an outer side than the reference portion. A movable portion that is a portion from a location supporting the fabric to an end portion of the support portion on the inner side of the outline of the fabric, and the movable portion supports the fabric on the same plane as the reference portion. It is characterized in that it can swing from the position to the reference portion with respect to the reference portion side to the opposite side of the fabric side with respect to the movable portion.

According to this aspect, in addition to the same effects as in any one of the first to third aspects, the step of the fabric due to the crease or the thick part on the movable part is kept away from the discharge head of the discharge unit. Can do. As a result, it is possible to prevent so-called head rubbing between the fabric and the ejection head.
It is also possible to extend the folds and folds of the fabric supported by the reference portion.

According to a fifth aspect of the present invention, in any one of the first to third aspects, the support portion includes a reference portion that supports a central portion inside the outline of the fabric, and an outer side than the reference portion. A movable portion that is a portion from a location supporting the fabric to an end portion of the support portion on the inner side of the outline of the fabric, and the movable portion supports the fabric on the same plane as the reference portion. It is the structure which can bend | curve from the position to the cloth side on the basis of this movable part to the opposite side.
According to this aspect, in addition to the same effects as any one of the first to third aspects, the same effects as the fourth aspect can be obtained.

According to a sixth aspect of the present invention, in the fourth or fifth aspect, the dynamic friction coefficient of a portion of the movable portion that contacts the fabric is higher than the static friction coefficient of the portion of the reference portion that contacts the fabric. It is characterized by that.
According to this aspect, in addition to the same effects as the fourth or fifth aspect, when the movable part is bent, the fabric itself supported by the reference part has an appropriate tension that does not completely stretch. The folds and folds of the fabric supported by the reference portion can be reliably extended. As a result, when the textile printed fabric is moved from the support portion to another location, and the pulling force is not applied to the fabric, the characters and designs printed on the textile are distorted. It is possible to reduce the problem.

(A)-(C) are front sectional drawing which shows a mode that the collar of a T-shirt is extended moderately.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a side view showing an outline of the ink jet textile printing apparatus 1 of the present embodiment.
As shown in FIG. 1, the ink jet textile printing apparatus 1 of this embodiment includes a discharge unit 2, a support unit 11, and a feeding unit 6. Among these, the ejection unit 2 includes a carriage 3, an ejection head 4, and a nozzle 5. For example, the carriage 3 is configured to be movable in a width direction X with respect to the feed direction Y of the support portion 11 by a known moving means (not shown). For example, it can move while being guided by a guide shaft under the power of a motor controlled by a control unit (not shown). Further, the ejection head 4 is provided on the carriage 3. A nozzle 5 for discharging ink is formed on the surface of the discharge head 4 on the support portion 11 side. Needless to say, the ejection of ink is controlled by the controller.

Moreover, the support part 11 is provided in the position which can oppose the discharge part 2, and can support T-shirt C which is an example of a fabric.
Furthermore, the feeding means 6 is configured to move the support portion 11 in the feeding direction Y. As an example, the feeding means 6 includes a support base 10, a guide portion 9, a pulley 7, and a belt 8.

  Among these, the support base 10 is comprised so that the support part 11 may be attached. Further, the guide portion 9 can guide the support base 10 in the feed direction Y. Furthermore, a belt 8 is wound around the pulley 7. One of the plurality of pulleys 7 is configured to be driven by the power of a motor (not shown). Further, a part of the belt 8 is locked to a part of the support base 10.

Therefore, the power of the motor is transmitted to the support base 10 and the support portion 11 moves in the feed direction Y.
The T-shirt C can be printed by moving the carriage 3 in the width direction X while ejecting ink while intermittently moving the support portion 11 in the feed direction Y. Here, “textile printing” refers to printing and dyeing a pattern on a fabric with ink.
The Z-axis direction is the vertical direction.

Then, the support part 11 of a present Example is demonstrated in detail.
2A and 2B are perspective views showing the support portion 11 of the present embodiment. 2A shows a state in which the movable portion 14 is not bent with respect to the reference portion 13. On the other hand, FIG. 2B shows a state in which the movable portion 14 is bent downward in the vertical direction with respect to the reference portion 13.

3A and 3B are perspective views showing a state in which the T-shirt C is placed on the support portion 11 of the present embodiment. 3A shows a state in which the movable part 14 is not bent with respect to the reference part 13. On the other hand, FIG. 3B shows a state in which the movable part 14 is bent vertically downward with respect to the reference part 13.
4A and 4B are plan views showing a state in which the T-shirt C is placed on the support portion 11 of the present embodiment. 4A shows a state in which the movable portion 14 is not bent with respect to the reference portion 13. On the other hand, FIG. 4B shows a state in which the movable part 14 is bent vertically downward with respect to the reference part 13.

As shown in FIGS. 2 to 4, as described above, the support portion 11 of this embodiment can support the T-shirt C that is an example of the fabric. Specifically, the support portion 11 includes a reference portion 13 and a movable portion 14. Among these, the reference | standard part 13 is a part fixed with respect to the support stand 10 mentioned above. On the other hand, the movable portion 14 is provided outside the reference portion 13, and is provided so as to be swingable in a direction away from the ejection head 4 (downward in the vertical direction) with respect to the reference portion 13 around the connection portion with the reference portion 13. It has been.
Note that the swinging mechanism may be configured such that the movable portion 14 swings by providing a hinge portion 15 (see FIGS. 5A to 5C) at a connection location with the reference portion 13. Alternatively, the movable portion 14 may be configured to swing when the thickness of the connection portion with the reference portion 13 is reduced and the connection portion is bent.

Moreover, the support part 11 has a shape similar to the shape of the T-shirt C which is an example of the fabric to support.
Here, the “similar shape” refers to a shape having an edge parallel to the outline of the fabric (T-shirt C) in a range of more than half.
Furthermore, the support part 11 has an alignment reference part 12 in which at least a part of the support part 11 protrudes outside the outline C6 of the T-shirt C which is an example of the fabric (FIG. 3A). And FIG. 4 (A)).

The alignment reference portion 12 is configured to protrude from both sides of a T-shirt C, which is an example of a fabric, in at least one direction. That is, the alignment reference portion 12 of the support portion 11 is provided in accordance with the shape and size of the T-shirt C that is the object to be printed.
When the user sets the T-shirt C on the support portion 11, the user adjusts the amount of the alignment reference portion 12 protruding from both sides of the T-shirt C in one direction so as to be substantially the same.

Thereby, the position of the T-shirt C can be easily aligned with the center of the support portion 11 in one direction.
The amount of protrusion is desirably about 2 to 4 cm. If the protruding amount is too large, it is difficult to make the protruding amounts substantially the same on both sides, and it is difficult to match the center. Similarly, if the amount of protrusion is too small, it is difficult to determine whether or not it protrudes on both sides, and it is difficult to adjust to the center.

In this embodiment, the alignment reference portion 12 is provided so as to protrude from both sides of the T-shirt C in each of the feed direction Y and the width direction X of the T-shirt C. Thereby, the position of the T-shirt C can be easily aligned with the center of the support portion 11 in each of the feed direction Y and the width direction X of the T-shirt C.
In the present embodiment, the alignment reference portion 12 protrudes outward from both sides of the T-shirt C, but is not limited thereto. In one direction, it may be configured to protrude outward from one of the two sides. This is because the technical idea is that the T-shirt C is set so that the alignment reference portion 12 protrudes and the position of the T-shirt C with respect to the support portion 11 can be aligned. For example, you may comprise so that the color of the reference | standard part 12 for alignment may differ from the color of another part so that it may be distinguished from another part easily. Further, a mark may be attached to the alignment reference portion 12. Furthermore, a mark such as a line may be attached to the boundary between the alignment reference portion 12 and other portions. This is because the position of the T-shirt C can be easily aligned with the center of the support portion 11.

Further, the movable portion 14 is provided outside the reference portion 13 and is provided so as to support the T-shirt C5 (C) on the inner side of the outline C6 of the T-shirt C. That is, the movable portion 14 has the alignment reference portion 12.
Furthermore, a cloth tape 16 as an example of a friction member is attached to the movable portion 14 as will be described in detail later. As a result, when the movable portion 14 supporting the T-shirt C is bent downward from the state shown in FIGS. 3A and 4A as shown in FIGS. 3B and 4B. The collar W (see FIG. 5A) of the T-shirt C4 supported by the reference portion 13 can be extended.

  Then, after aligning the position of the T-shirt C with respect to the support portion 11, the user moves the movable portion 14 supporting the T-shirt C from the state of FIGS. 3A and 4A to FIG. B) and bend downward in the vertical direction as shown in FIG. Thereby, the thicker portions of the fabric such as the collar portion C3, the folded portion C1 of the sleeve fabric, the folded portion C2 of the hem fabric, and the like, are lower in the vertical direction than the thickness of the fabric portion supported by the reference portion 13. Can be moved to.

As a result, when printing is performed by the discharge unit 2, the discharge head 4 comes into contact with a thick portion of the fabric such as the collar portion C3, the folded portion C1 of the sleeve fabric, the folded portion C2 of the hem fabric, and so-called head rubbing. Can be prevented from occurring.
After the textile printing by the discharge unit 2 is completed, the movable part 14 is returned from the state shown in FIGS. 3B and 4B to the state shown in FIGS. 3A and 4A. Then, the T-shirt C is lowered from the support portion 11 and the next T-shirt C is set.

Then, the effect of the cloth tape 16 which is an example of a friction member is demonstrated.
FIGS. 5A to 5C are front cross-sectional views showing how the heel W of the T-shirt C is stretched moderately.
As shown in FIG. 5A, there is a case where there is a heel W on the T-shirt C at a place supported by the reference portion 13. The reason for this is that when the user places the T-shirt C on the support 11 and aligns the center, the heel is stretched by hand, but there is a possibility that it cannot be fully stretched. Moreover, it is because there is a possibility that small wrinkles W may not be noticed.

  Then, as shown in FIG. 5 (B), the movable portion 14 is gradually bent downward in the vertical direction from the state of FIG. 5 (A). Here, the dynamic friction coefficient between the T-shirt C and the fabric tape 16 is configured to be higher than the static friction coefficient of the reference portion 13 where the T-shirt C is in contact with the T-shirt C. Further, the coefficient of dynamic friction between the T-shirt C5 (C) and the fabric tape 16 can extend the heel W of the T-shirt C4 on the reference portion 13 by the movement of the movable portion 14, and can be on the reference portion 13. It is provided in a “moderate” size so as not to stretch the T-shirt C4. Not only the dynamic friction coefficient between the T-shirt C5 (C) and the cloth tape 16, but also the static friction coefficient between the T-shirt C5 (C) and the cloth tape 16 is the same.

  As a technical idea, the dynamic friction coefficient of the portion that contacts the T-shirt C5 (C) in the movable portion 14 is higher than the static friction coefficient of the portion that contacts the T-shirt C4 (C) in the reference portion 13. And it should just be the “moderate” size. Therefore, even if the cloth tape 16 is not affixed to the movable part 14, the surface of the movable part 14 that is in contact with the T-shirt C5 (C) may be relatively processed so as to increase the dynamic friction coefficient. . Moreover, you may give the process in which the said static friction coefficient becomes low relatively to the surface of the location which contacts T-shirt C4 (C) in the reference | standard part 13. FIG.

  Therefore, by gradually bending the movable portion 14 downward in the vertical direction, the location C5 supported by the movable portion 14 in the T-shirt C tends to move together with the movable portion 14. At this time, the movable part 14 acts so as to “reasonably” pull the portion C5 supported by the movable part 14 in the T-shirt C via the cloth tape 16 to the outside. As a result, the portion C4 supported by the reference portion 13 in the T-shirt C is pulled “moderately” to the outside on the movable portion 14 side, and the heel of the portion C4 supported by the reference portion 13 in the T-shirt C W is extended.

  As shown in FIG. 5C, the movable portion 14 is further bent downward in the vertical direction from the state of FIG. At this time, the portion C4 supported by the reference portion 13 in the T-shirt C is already “moderately” stretched to such an extent that the heel W is stretched. The static friction coefficient and the dynamic friction coefficient between the T-shirt C5 (C) and the cloth tape 16 are set to “moderate” sizes as described above. Therefore, the location C5 supported by the movable part 14 in the T-shirt C moves so as to slide relative to the movable part 14.

  At this time, there is no possibility that the T-shirt C4 on the reference portion 13 is stretched. As a result, when printing by the discharge unit 2 is executed, it is possible to execute printing by discharging ink to the portion C4 supported by the reference portion 13 of the appropriately stretched T-shirt C. That is, when the T-shirt C is lowered from the support portion 11 after discharge, there is no possibility that the T-shirt C is shrunk and the printed characters and designs are distorted.

In addition, as for the bending of the movable part 14, it is desirable to bend both sides at the same timing. This is because there is a possibility that the position of the T-shirt C with respect to the support portion 11 may be shifted if it is bent one by one.
Alternatively, the T-shirt C5 on the movable part 14 may be lightly sandwiched between the movable parts 14 so that the movable part 14 acts so as to be “moderately” pulled when the movable part 14 is swung downward. Good. This is because the heel W of the portion C4 supported by the reference portion 13 of the T-shirt C can be extended as in the above embodiment.

  Moreover, in the state of FIG. 2 (A), FIG. 3 (A), FIG. 4 (A), and FIG. 5 (A), the movable part 14 is configured to be flush with the reference part 13 as an example. It does not have to be the same plane. As a technical idea, it is sufficient that the movable part 14 acts so as to be “moderately” pulled outward as described above by moving (bending) downward in the vertical direction. Therefore, the movable portion 14 may be slightly inclined with respect to the reference portion 13 in the states of FIGS. 2 (A), 3 (A), 4 (A), and 5 (A).

  The inkjet textile printing apparatus 1 of the present embodiment includes a support unit 11 that supports a T-shirt C that is an example of a fabric, and a discharge unit 2 that discharges ink to the T-shirt C supported by the support unit 11. The support portion 11 includes a reference portion 12 for alignment that protrudes at least partially outside the outline C6 of the supported T-shirt C for the alignment of the T-shirt C with respect to the support portion 11. It is characterized by being.

Further, in this embodiment, the alignment reference portion 12 is configured to protrude outward from both sides of the T-shirt C in at least one direction.
Furthermore, in this embodiment, the shape of the edge of the support portion 11 is a shape having an edge parallel to the outline C6 of the T-shirt C in a range of more than half.

  Further, in the present embodiment, the support portion 11 is a reference portion 13 that supports the center portion C4 inside the outline C6 of the T-shirt C, and is outside the reference portion 13 and inside the outline C6 of the T-shirt C. The movable portion 14 is a portion from a portion that supports the T-shirt C5 (C) to the end portion of the support portion 11, and the movable portion 14 has the same surface as the reference portion 13 and the T-shirt C. It is characterized in that it can swing from the supporting position to the side opposite to the T-shirt C side with the movable part 14 as a reference with respect to the reference part 13 as a center.

  Furthermore, in this embodiment, the dynamic friction coefficient of the portion that contacts the T-shirt C5 (C) in the movable portion 14 is higher than the static friction coefficient of the portion that contacts the T-shirt C4 (C) in the reference portion 13. It is characterized by that.

[Other embodiments]
In the above-described embodiment, the movable portion 14 is bent and swung with respect to the reference portion 13 downward in the vertical direction with the connection portion between the reference portion 13 and the movable portion 14 as the center. However, the present invention is not limited to this.
As a technical idea, it suffices that the T-shirt C4 on the reference portion 13 can be stretched outward by “moderate” force by moving a part of the movable portion (14) downward in the vertical direction. Further, it is only necessary to move a portion where the fabric is thick, such as the collar portion C3, the folded portion C1 of the sleeve fabric, and the folded portion C2 of the hem fabric to a position where it does not contact the discharge head 4.

Accordingly, the movable portion (14) may be bent downward in the vertical direction with respect to the reference portion 13 at or near the connection portion between the reference portion 13 and the movable portion (14). Further, in the state before the movable part (14) is bent downward in the vertical direction, as described above, the reference part 13 and the movable part (14) may not be on the same plane.
In addition, the same code | symbol is used about the member similar to the Example mentioned above, The description is abbreviate | omitted.

  In another embodiment, the support portion 11 includes a reference portion 13 that supports a central portion C4 inside the outline C6 of the T-shirt C, an outside of the reference portion 13, and an inside of the outline C6 of the T-shirt C.
