Description

  The present invention relates to a composite data processing apparatus for processing embroidery data for embroidering an embroidery pattern on a cloth by an embroidery sewing machine and print data for printing by a printer, and in particular, as a pre-stage for embroidering a cloth, By printing in the same color as the thread color in advance, even if the embroidery seams are rough (the thread density is rough) and the background can be seen through, the background can be seen through by printing the same color as the embroidery. It relates to the thing which prevented it.

  Conventionally, using embroidery data composed of a large number of needle drop data (so-called stitch data), not only embroidery is performed on a fabric by an embroidery sewing machine, but recently, the embroidery data is expanded into print data which is bitmap data, The embroidery pattern can be printed with a printer.

For example, the fabric (fabric) processing method described in Patent Document 1 extracts an outline of an embroidery area based on embroidery data created from image data, and further applies the entire embroidery area defined by the outline. By developing the data into bitmap data, print data to be printed on at least a part of the embroidery area is created from the embroidery data, and the embroidery is embroidered on the fabric based on the embroidery data. Thus, there has been disclosed a combined processing technique of embroidery and printing in which printing is performed by overlapping an upper thread embroidered by an ink jet printer so that gloss can be exerted on the entire surface of the embroidery area and expresses the texture of the embroidery.
JP 2004-263350 A (pages 6-7, FIG. 3)

  By the way, when embroidering a fabric with an embroidery sewing machine to form a character pattern or various design patterns, the embroidery pattern has few embroidery patterns consisting only of a linear pattern portion. In many cases, the outline (contour line) includes a curved portion including a bent portion at least partially. In addition, satin stitches are particularly often used as stitches that express the texture of embroidery, and thread density that is stitch density is set in advance in the embroidery data.

  Therefore, depending on the value of the yarn density, the yarn density outside the curved pattern portion (outside in the bending direction) becomes coarser than the yarn density inside the curved pattern portion (inside the bending direction), and the embroidered fabric is You can see through. However, using the composite processing technique described in the above-described fabric (fabric) processing method described in Patent Document 1, the purpose of overprinting from the upper side of the embroidered upper thread is to give gloss in the embroidery area. Therefore, it is not intended to prevent the fabric color different from that of the embroidery thread from being seen through.

  Furthermore, when printing is performed over embroidery, printing and embroidery, such as a technical idea that simplifies the printing process and reduces ink consumption, a technical idea that simplifies (convenience) the embroidery process by the printing process, etc. Since the technical cooperation that gives support relations between each other has not been demonstrated, the time required for the embroidery process and the printing process has not been shortened in cooperation with each other, etc. There's a problem.

  The composite data processing apparatus according to claim 1 includes embroidery data for embroidering an embroidery pattern with an embroidery machine, print data for printing on a printer over at least a part of an embroidery area to be embroidered based on the embroidery data, and And a curved pattern portion detecting means for detecting a curved pattern portion that is curved in the contour of the embroidery pattern embroidered by the embroidery data based on the embroidery data, and detected by the curved pattern portion detecting means. Print data creation means for creating print data for printing in the same color as the embroidery thread color is provided on all or part of the curved pattern portion.

  When a curved pattern portion in which the contour of the embroidery pattern is curved is detected among the embroidery patterns embroidered by the embroidery data, printing is performed for printing on all or part of the curved pattern portion with the same color as the embroidery thread color. Data is created. Therefore, after printing with the created print data, embroidery is performed based on the embroidery data. That is, even when the stitches of the embroidery pattern are coarse, the fabric color is not seen through because the fabric is printed in a solid shape with the same color as the thread color on at least the coarse fabric portion.

  According to a second aspect of the present invention, there is provided the composite data processing apparatus according to the first aspect of the invention, further comprising contour line data creating means for creating contour line data for demarcating the contour of the embroidery pattern based on the embroidery data.

Printing can be used in combination only with a curved pattern portion where the color can be seen through, that is, a necessary minimum amount. Thereby, useless consumption of printing processing and printing ink can be suppressed. Other effects similar to those of the first aspect are obtained.

  According to the invention of claim 4, the print data creation means creates print data in which at least a half or more of the curved outer portion is printed in the curved pattern portion. Since printing is performed only in a region where at least half of the curved outer portion is easy to see colors, the printing time and consumption of printing ink can be kept to a minimum. Other effects similar to those of any one of claims 1 to 3 are provided.

  Next, a data processing control routine executed by the control device of the composite data processing apparatus 1 will be described with reference to the flowchart of FIG. However, the symbol Si (i = 11, 12, 13,...) In the figure is each step.

  When “composite data processing” is selected from the main menu (not shown) displayed on the display 14, for example, as shown in FIG. 7, a “print processing menu” is displayed. Accordingly, when the “curved pattern portion” is selected as the item “print target”, the composite data processing control shown in FIG. 4 is started.

  When this control is started, first, embroidery data selected in advance from a plurality of embroidery data stored in a CD-ROM or hard disk is read and stored in the embroidery data memory of the RAM 23 (S11). Next, based on the embroidery data, an embroidery data analysis process is executed in order to obtain an embroidery area designated by a stitch type and thread color, such as satin stitches and tatami stitches, that is, an outline of an embroidery pattern. (S12).

  The analysis process of the embroidery data will be briefly described. First, each needle drop point (total of n) included in the embroidery data is set to Pi (i = 1, 2,..., N) in the sewing order. . An initial value “1” is set to the variable i, and an orthogonal coordinate system is set with the needle drop point Pi as the origin. As shown in FIGS. 6A and 6B, an X axis is provided in a direction from the needle drop point Pi to the needle drop point Pi + 1, and the X axis is counterclockwise about the needle drop point Pi. The Y axis is provided in the direction rotated 90 °, the coordinates (Xi + 1, 0) of the needle drop point Pi + 1 and the coordinates (Xi + 2, Yi + 2) of the needle drop point Pi + 2 are read, and the coordinates of the RAM 23 are read. Store in memory.

  Next, the values of Xi + 1 and Xi + 2 are compared. If Xi + 1 is larger, the attribute of the needle drop point Pi + 1 is set to the temporary contour, and Xi + 2 ≧ Xi + 1. In the case of, the attribute of the needle entry point Pi + 1 is set as a temporary run. Here, as shown in FIG. 6A, when the needle drop point Pi + 1 is a contour point, the stitches Si and Si + 1 on both sides thereof are folded back. In this case, the value of Xi + 2 is smaller than the value of Xi + 1 (Xi + 2 <Xi + 1).

  Therefore, in this case, if the attribute of the needle drop point Pi + 1 is a temporary contour in the sense that it can be estimated as a contour point, and the needle drop point Pi + 1 is a running point, as shown in FIG. + 2 ≧ Xi + 1. Accordingly, in this case, the attribute of the needle drop point Pi + 1 is assumed to be a temporary run in the sense that it can be estimated as a run point. The needle drop points P1 and Pn are forcibly given a temporary running attribute.

  As described above, when the value of the variable i is sequentially increased, these processes are repeatedly executed. When i + 1 = n, that is, for all the needle drop points Pi + 1 where i + 1 = 2 to n−1. The attribute of provisional contour or provisional running is given. Therefore, the classification of the stitch format is performed as follows. First, while setting 1, 2, 3,... Sequentially to the variable i, it is determined whether or not the provisional contour attribute is given to the needle drop point Pi + 1. If Pi + 1 is a temporary run, the next large value is set in the variable i and the determination is made again.

  On the other hand, when the needle drop point Pi + 1 is a temporary contour, it is determined whether or not the needle drop point Pi + 1 is adjacent to the needle drop point assigned the provisional running attribute, that is, the needle drop point Pi or Pi. Judge whether any of +2 is a temporary run. If it is adjacent to the temporary run, Yi + 2 stored in the loop in which the needle drop point Pi + 1 is given the temporary contour attribute is read.

  If the needle entry point of the temporary contour arranged before and after the needle entry point Pi is different from Yi + 2 stored in the same manner, the stitch attribute of the needle entry point Pi + 1 is temporarily set. In the case of a tatami contour and the same sign, the stitch attribute of the needle entry point Pi + 1 is assumed to be a temporary run.

  On the other hand, when the needle drop point Pi + 1 of the temporary contour is not adjacent to the needle drop point of the temporary run, and the sign of Yi + 2 is alternately replaced with the front and back temporary contours, the needle drop point If Pi + 1 is a temporary satin contour and the signs of Yi + 2 are not alternately changed, the needle drop point Pi + 1 is assumed to be a temporary run.

  Finally, the shape of the needle drop points before and after, the thread density, the tatami pattern, etc. are detected for all the needle drop point data to which the attribute of the temporary tatami outline is given, and the contour of the embroidery pattern is determined based on the detected shape. A process for determining is executed, and a tatami embroidery area for performing tatami stitching is determined.

  Further, for all the needle drop point data to which the attribute of the temporary satin contour is given, the shape of the needle drop points before and after, the thread density, etc. are detected, and the process of determining the contour of the embroidery pattern is executed based on the detected shape. Determine the satin embroidery area for satin sewing.

  Finally, with respect to the data of the remaining needle entry points that have not been established as temporary tatami contours or temporary satin contours, use the needle entry points as running points to confirm according to the stitch pitch and shape, and perform running stitching. Confirm the running embroidery area.

  Next, when the content preset as “print target” by the print processing menu is “curved pattern portion” (S13), print area setting process control (see FIG. 5) is executed (S14). When this control is started, first, a pair of contour portions connecting the needle drop points opposed to both sides on the contour of the embroidery pattern based on the coordinates of the needle drop points defining the contour of the embroidery pattern obtained in S12. The needle drop point interval in one contour portion, that is, the large needle drop point interval is greater than or equal to a predetermined ratio (for example, 1.5 times) with respect to the needle drop point interval in the other contour portion, that is, the small needle drop point interval. Detection processing for detecting an embroidery pattern portion having a length as a curved pattern portion is executed (S31).

  Next, in the curved pattern portion detected in S31, a calculation process for obtaining a printing area which is at least half of the area outside the curved line is executed (S32), and this control is terminated, and the composite data processing control proceeds to S15. Return. In this print area calculation process, for example, when the embroidery pattern is the character pattern “C” shown in FIG. 8, five embroidery pattern portions indicated by reference numerals WM1 to WM5 are detected as curved pattern portions.

  Therefore, in each of the curved pattern portions WM1 to WM5, a fan-shaped embroidery region having a width dimension of more than half of the pattern width dimension from the outer contour portion OL to the inner contour portion IL on the outer contour portion OL side (see FIG. 11).

  Next, in the composite data processing control, print data to be printed in the arc-shaped embroidery area obtained in S32 is created (S15), and this control is finished. In the print data creation process, based on the coordinates of a plurality of needle drop points constituting the outline of the embroidery pattern obtained in S12, an area that is inward by a minute predetermined dimension from the line segment that connects adjacent needle drop points Printing data that fills the inside of the paper is required.

  By the way, since the embroidery data is created for each embroidery area composed of a plurality of blocks divided when creating the embroidery data, the thread color data indicating the thread color of the thread when performing embroidery is for each embroidery area. Has been added. Moreover, each of the curved pattern portions thus obtained is related to the block. Accordingly, the thread color of the print data relating to the curved pattern portion is the same color as the thread color indicated by the embroidery thread color code included in the embroidery data including the curved pattern portion.

  Here, the curved pattern portion detection means is configured from the print area setting process control, particularly S31, and the print data creation means is configured from S15, etc., in the composite data processing control.

  Next, as described above, the embroidery pattern is embroidered based on the embroidery data, and the combined data processing operation is performed in which a part of the curved pattern portion curved at the embroidery pattern outline is printed in the same color as the thread color of the embroidery. The effects will be described.

  First, from the “print processing menu” shown in FIG. 7, when the operator selects the first “curved pattern portion” as the item “print target” with the block cursor K, as shown in FIG. Embroidery data (see FIG. 9) for the pattern “C” is read. In this case, the embroidery data consists of a large number of stitch data set in one or a plurality of embroidery pattern portions, and a thread color code for designating the thread color of the embroidery thread is stored at the head of each embroidery pattern portion. ing.

  Here, as shown in FIG. 8, in the character pattern “C” based on the embroidery data, in particular, in the outer contour portion OL, there are a plurality of portions that can be seen through in white, that is, portions in which the ground color of the fabric W can be seen through. Exists. This is because the thread density in each block set at the time of creating the embroidery data is the same in the inner contour portion IL and the outer contour portion OL, so that the interval between the needle drop points in the outer contour portion OL is large. This is because the embroidery stitches become rough.

  After the analysis process is performed on the embroidery data, a curved pattern portion that is curved in the contour is detected. For example, the stitches based on a part of the embroidery data of the curved pattern portion WM3 shown in FIG. 8 are satin stitches as shown in FIG.

  Therefore, in the contour of the character pattern “C”, a pair of contour portions connecting a needle drop point An that defines the contour of the outer contour portion OL facing each other and a needle drop point Bn that defines the contour of the inner contour portion IL. For example, as shown in FIG. 10, the intervals (A1, A2, A3, A4...) Of the needle drop points (a1, a2, a3, a4...) In the outer contour portion OL are the inner contour portions. The length of the needle drop points (b1, b2, b3, b4...) In IL is a predetermined ratio (for example, 1.5 times) or more with respect to the interval (B1, B2, B3, B4...). The embroidery pattern portion is detected as the curved pattern portion WM3.

  Thereafter, as shown in FIG. 8, the other curved pattern portions WM1, WM2, WM4, and WM5 are detected by the same curved pattern portion detection process. Further, for each of the five curved pattern portions WM1 to WM5 detected in this way, as shown in FIG. 11, in each of the curved pattern portions WM1 to WM5, a pattern extending from the outer contour portion OL to the inner contour portion IL. Of the width dimension D, arc-shaped embroidery areas SH1 to SH5 each having a width dimension Da that is more than half of the outer contour portion OL side are obtained.

  Then, print data for filling each of the embroidery areas SH1 to SH5 in a solid shape is created. This print data includes color information for printing in the same color as the thread color defined by the thread color code included in the embroidery data. Since the print data has been created in this way, as shown in FIG. 12, based on the print data, first, the ink jet printer 3 is applied to the fabric W set in the embroidery frame 5 in each of the five embroidery areas SH1 to SH5. Is printed.

  Thereafter, as shown in FIG. 12, the character pattern “C” is embroidered based on the embroidery data. As described above, the curved pattern portions WM1 to WM5 of the character pattern “C” have coarse stitches, and therefore, the stitches are printed in the same color as the thread color of the embroidery on a part of the curved pattern portions. The fabric W color in the curved pattern portions WM1 to WM5 can be reliably prevented from being seen through, and the texture of the embroidery pattern can be sufficiently exhibited.

  In the above description, an example in which print data for performing print processing on the curved pattern portions WM1 to WM5 has been described. However, not only the curved pattern portions WM1 to WM5 but also the curved pattern portions WM1 to WM5 are included. You may make it produce the print data for performing a printing process with respect to all the embroidery areas of the embroidery pattern which has.

  Next, from the “print processing menu” shown in FIG. 13, the operator selects, for example, “entire embroidery area” as the item “print target” with the block cursor K, and further, the item “thread density condition”. When “Rough thread density” is selected, it is determined in S13 of the composite data processing control described above that the print target is “the entire embroidery area” (S13), and the thread density calculation process is executed (S13). S17).

  Since this thread density calculation process is a well-known technique, a detailed description thereof will be omitted. Briefly, the embroidery data is obtained by dividing the embroidery area corresponding to the embroidery pattern into a plurality of blocks as described above. And it is created for each block. Therefore, in response to the analysis result of the analysis processing in S12, the linear embroidery region portion in which the thread density of the linear embroidery region portion in the embroidery region, that is, the lengths of the outer contour portion OL and the inner contour portion IL are substantially equal. Or the length of the outer contour portion OL and the total number of needle drop points in the outer contour portion OL, or the length of the inner contour portion IL and the inner contour portion. The yarn density is determined based on the total number of needle drop points in the IL.

  However, when there is no linear embroidery region portion, the average value of these two yarn densities is the same for the small difference between the yarn density in the inner contour portion IL and the yarn density in the outer contour portion OL. Adopted as yarn density.

  Next, when the thread density condition set in the print processing menu is “rough thread density” (S18), the embroidery data with the thread density coarsened to 2/3 (2/3) is calculated again. The embroidery data creation process required by the above is executed (S19). Next, based on the embroidery data read in S11, print data for creating a solid print by filling the entire embroidery area embroidered by the embroidery data is created (S15), and this control is terminated.

  Here, the yarn density calculating means is composed of the composite data processing control, particularly S17, and the print data creating means is composed of the composite data processing control, especially S15.

  Next, as described above, the thread density of the embroidery data is changed to embroidery data coarsened to about two-thirds, and the entire embroidery area embroidered with the embroidery data is printed in the same color as the embroidery thread color. The operation and effect of the composite data processing for creating print data to be subjected to will be described.

  First, from the “print processing menu” shown in FIG. 13, the operator selects “whole embroidery area” as the item “print target” with the block cursor K, and “rough thread density” as the item “thread density condition”. As shown in FIG. 14, the embroidery data (see FIG. 9) for the character pattern “C” selected in advance is read.

  Here, as shown in FIG. 14, the thread density of the character pattern “C” embroidered by the embroidery data is “6.0 / mm”, and the character pattern “C” embroidered by the embroidery data is Like the character pattern “C” shown in FIG. 8, there is no white portion that can be seen through, but a long embroidery time is required. Therefore, as shown in FIG. 15, the embroidery data in which the thread density “6.0 / mm” is changed to the thread density “4.0 / mm” of 2/3 roughness is created by calculation.

  Then, as shown in FIG. 16, solid print data for filling the entire embroidery region of the character pattern “C” is created. This print data has color information for printing in the same color as the thread color defined by the thread color code included in the embroidery data. Then, as shown in FIG. 12, based on the print data, first, the fabric W set in the embroidery frame 5 is printed by the inkjet printer 3, and then embroidered by the embroidery data so as to overlap the print. .

  In this way, the thread density of the embroidery data used for embroidery is forcibly corrected to a coarser thread density, and embroidery is performed based on the corrected coarse thread density embroidery data in addition to the printing process. In order to prevent see-through, the printing time required for printing is longer than the embroidery processing time required only for embroidery with fine thread density embroidery data. However, since the thread density is coarse, the embroidery is such that the fabric color can be seen through the seam. By doing so, the embroidery time required for embroidery can be significantly shortened more than the printing time required for printing. As a result, it is possible to reliably prevent the fabric color from being seen through and to shorten the processing time.

  In addition, since technical cooperation is exhibited by providing a support relationship between printing and embroidery, the time required for embroidery processing and printing processing can be effectively shortened while mutually cooperating. In the above description, an example has been described in which a coarse thread density is set for the entire embroidery area, and print data is generated for printing in the same color as the embroidery thread color for the entire embroidery area. The embroidery data is corrected so that the thread density is coarse with respect to a part of the embroidery area, and printing is performed with the same color as the thread color of the embroidery over only a part of the embroidery area or over the entire embroidery area. You may make it produce the printing data for performing.

  When printing processing is performed on the fabric W by the ink jet printer 3 using print data for printing only the region where the coarse yarn density is set, in other words, only the region where the fabric W may be seen through, the entire embroidery region is obtained. On the other hand, the ink consumption can be reduced as compared with the case where the printing process is performed.

  Further, in the above description, when the thread density is set to be coarse, an example in which the thread density is set to 2/3 based on the original embroidery data has been described, but this is exemplified as a thread density that can maintain the texture of the embroidery. However, the yarn density may be set to 2/3 or less.

  Next, from the “print processing menu” shown in FIG. 17, the operator selects, for example, “entire embroidery region” as the item “print target” by the block cursor K, and further, the item “thread density condition”. When “below the predetermined thread density” is selected, it is determined in S13 of the above-described composite data processing control that the object to be printed is “the entire embroidery area” (S13), and the above-described thread density calculation process is executed. (S17).

  Next, when the “thread density condition” set in the print processing menu is “predetermined thread density” (S18), the thread density value obtained in S17 is a predetermined value (for example, 2.5). If it is larger than the book / mm), that is, if the fabric W cannot be seen through the embroidered embroidery stitch (S20: No), this control is terminated. However, when the value of the thread density obtained in S17 is equal to or smaller than a predetermined value, that is, when the fabric W can be seen through the embroidered embroidery stitch (S20: Yes), it is based on the embroidery data read in S11. Thus, the print data for printing the whole embroidery area embroidered by the embroidery data in a solid shape is obtained (S15).

  Here, the yarn density calculating means is composed of the composite data processing control, particularly S17, and the thread density determining means is composed of S20, especially the composite data processing control, and the print data generating means is composed of S15, etc. of the composite data processing control. Is configured.

  Next, as described above, it is determined whether or not the thread density of the embroidery data is a predetermined thread density, and only when the thread density is less than a predetermined value and the fabric color can be seen through the stitches. The operation and effect of composite data processing for creating print data for printing the entire embroidery area embroidered with embroidery data with the same color as the thread color of the embroidery will be described.

  First, from the “print processing menu” shown in FIG. 17, the operator selects “entire embroidery area” as the item “print target” with the block cursor K, and the item “thread density condition” is “predetermined thread density or less”. ”Is read, the embroidery data for the character pattern“ C ”shown in FIG. 14 is read. If the thread density of the embroidery data is“ 5.0 / mm ”, the stitches are clogged. Since the lower fabric color cannot be seen through the embroidery stitch, only embroidery based on the embroidery data is performed.

  However, when the embroidery data for the character pattern “C” shown in FIG. 15 is read and the thread density of the embroidery data is “2.5 / mm”, the lower fabric is passed through the embroidery stitch. Since the color is seen through, as shown in FIG. 16, print data is created that fills the entire embroidery region of the character pattern “C” in a solid shape. This print data includes color information for printing in the same color as the thread color defined by the thread color code included in the embroidery data.

  Then, as shown in FIG. 12, based on the print data, first, solid ink-like printing is applied to the entire embroidery area on the fabric W set in the embroidery frame 5 by the inkjet printer 3. Thereafter, the image is embroidered with the embroidery data so as to overlap the printing.

  In this way, the entire embroidery area on the fabric only when the thread density of the stitch of the embroidery pattern to be embroidered based on the embroidery data is less than a predetermined value and the stitches are so coarse that the fabric color can be seen through. The embroidery is printed in a solid color with the same color as the embroidery thread, so even if the embroidery is applied with coarse thread density stitches, it is possible to ensure that unsightly fabric colors can be translucent with only a very short processing time. Can be prevented.

  In the above description, the thread density of the embroidery area is obtained, and when the thread density is equal to or lower than a predetermined value, print data for printing the entire embroidery area with the same color as the embroidery thread color is created. Although the example has been described, it is determined whether or not there is an area where the thread density is a predetermined value or less in the embroidery area, and when there is an area where the thread density is a predetermined value or less, only the area or the area Printing data for printing the entire embroidery region including the same color as the thread color of the embroidery may be created.

  Here, when printing processing is performed on the fabric W by the inkjet printer 3 using print data for printing only the region, in other words, the region where the fabric W may be seen through, the entire embroidery region is printed. The amount of ink consumed can be reduced compared to the case where the printing process is performed.

  Next, a modified form of the embodiment will be described.

Then, using the contour line data, a curved pattern portion is detected on the basis of the embroidery data and the contour line data in S14, and a print area of about half or more of the curved pattern portion outside the curve is obtained. May be.

  Further, when creating the print data in S15, it may be obtained by calculation based on the contour line data constituting the print area.

  2) In the composite data processing control, the embroidery area is printed and then embroidered. However, the embroidery area may be embroidered first and then printed.

  3] Although the composite data processing apparatus 1 is provided separately from the embroidery sewing machine 2, the control unit 42 of the embroidery sewing machine 2 may be configured to have the composite data processing apparatus 1 as well. In this case, it is not necessary to separately prepare the composite data processing apparatus 1 composed of a personal computer, and the embroidery sewing machine 2 can be used effectively.
