BACKGROUND OF THE INVENTION
  The present invention relates to an embroidery data processing apparatus capable of creating sewing data for performing under-sewing on an embroidery area, and a computer-readable recording embroidery data processing program for operating the embroidery data processing apparatus The present invention relates to a recording medium.
[0002]
[Prior art]
  Conventionally, sewing data for sewing an embroidery pattern has been created by an expert by determining the position coordinates of a needle drop point for each stitch, but in recent years, the shape, position, size, An embroidery data processing apparatus has been developed and widely used which can automatically create sewing data for an embroidery pattern to some extent by demarcating an embroidery body that defines the direction of stitches, thread density, and the like.
[0003]
  In particular, when embroidering to fill the inside of a closed area with seams, sewing data for under-stitching is created for the purpose of giving a three-dimensional effect and preventing the work cloth from shrinking as the embroidery progresses. Or processing devices have been devised and commonly used.
[0004]
  Regarding the method of creating the sewing data for performing the under-sewing, generally, the under-sewing area outline that defines the shape of the area to be sewn inside the closed area surrounded by the outline that defines the shape of the embroidery area There is known a method of creating sewing data for performing under-sewing based on the outline of the under-sewing area, and in particular, Japanese Patent Application Laid-Open No. 4-314490 filed earlier by the present applicant. Discloses a data generation method that takes into account the case where the outlines of the lower sewing area self-intersect. In the method disclosed here, when the outline of the lower sewing area self-intersects, the lower sewing area is divided into a plurality of partial lower sewing areas with the self-intersecting part as a boundary. This is a method of creating sewing data. However, in the data creation method disclosed in Japanese Patent Application Laid-Open No. 4-314490, there is no mention of a creation method of under-sewing data for connecting a plurality of partial under-sewing areas. There is a problem in that the connecting thread connecting the partial under-sewing areas protrudes outside the embroidery area.
[0005]
  In order to solve this problem, the present applicant has proposed an embroidery data processing apparatus shown in Japanese Patent Application No. 8-341554 filed earlier. In this proposed embroidery data processing apparatus, means for creating auxiliary under-sewing data for connecting a plurality of partial under-sewing areas is provided. The under-sewing data that does not protrude outside the area can be automatically created.
[0006]
[Problems to be solved by the invention]
  However, in the proposed embroidery data processing apparatus, for example, as shown in FIG. 5, the partial under-sewing area P <b> 2 that protrudes from the embroidery area G is the same as the partial under-sewing area P <b> 1 that does not protrude from the embroidery area G. Auxiliary under-sewing data for connecting the partial under-sewing area P2 can be created, but the partial under-sewing area P4 that also protrudes from the embroidery area G is not connected to other partial under-sewing areas. There is a problem that normal under-sewing data cannot be created because normal partial under-sewing data or auxiliary under-sewing data cannot be created.
[0007]
  The present invention has been made in order to solve the above-described problems. The purpose of the present invention is to prevent the transition thread connecting the partial lower stitch areas and the stitches of the lower stitch from protruding outside the embroidery area.

[0024]
  Further, in the embroidery data processing apparatus, a keyboard 16 on which operation keys for a user to select and execute processing are arranged, and an outline representing an embroidery shape is created and selected. Mouse 17 as a pointing device is provided, and an input interface is provided.-It is connected to the CPU 11 through the memory 15.
[0025]
  A communication line 20 is connected to the embroidery data processing apparatus via the output interface 18, and the created embroidery data is sent to the embroidery sewing machine 25 via the communication line 20. It is configured.
[0026]
  Next, the operation of the embroidery data processing apparatus according to this embodiment configured as described above will be described with reference to the flowchart of FIG. In the present embodiment, it is assumed that under-sewing data and main-sewing data are created for the embroidery region G shown in FIG.
[0027]
  When a program for creating embroidery data stored in the ROM 12 is started, first, in step S1, an outline for defining a lower stitch area is created. Specifically, as shown in FIG. 5, the outline of the under-sewing area (shown by a broken line in the figure) is located at a position that is inside by a predetermined distance from the outline that defines the shape of the embroidery area G. Is created.
[0028]
  In step S2, it is determined whether or not the underlining area created in step S1 intersects itself. Here, since the underline of the under stitch region created previously intersects itself, it is determined as YES and the process proceeds to step S3. If it is determined as NO, the process proceeds to step S5.
[0029]
  In step S3, the lower sewing area outline that self-intersects at three points A, B, and C is divided into a plurality of partial lower sewing area outlines in order to eliminate the self-intersection. Specifically, as shown in FIG. 5, the outline of the lower sewing area is divided into a plurality of partial lower sewing area groups that do not self-intersect with the self-intersecting part as a boundary. Partial partial sewing areas defined by the outlines of the partial lower sewing areas divided by the division processing here are shown as P1 to P4 in FIG.
[0030]
  In step S4, the self-intersections A, B, and C are set as the partial lower sewing start point or the partial lower sewing end point for the partial lower sewing areas P1 to P4. Here, the processing method for determining which self-intersection is set as the partial lower sewing start point or partial lower sewing end point of which partial lower sewing area is, for example, in the example shown in FIG. , P3, and P4 are determined in advance so as to be sewn in order of the self-intersection A, which is a connection point between the partial lower sewing area P1 and the partial lower sewing area P2, and the partial lower sewing area P1. The sewing end point and the partial lower sewing area P2 are determined as the partial lower sewing start point, and the self-intersection B, which is the connection point between the partial lower sewing area P2 and the partial lower sewing area P3, is set to the partial lower sewing area P2 and the partial lower sewing area P2. The self-intersection C, which is the connection point between the partial bottom stitching area P3 and the partial bottom stitching area P4, is determined as the partial bottom stitching end point and the partial bottom stitching of the partial bottom stitching area P3. Region P It is to determine the partial underlying stitch start point.
[0031]
  In step S5, the value of the total number N of partial under-sewing areas is set. Here, since there are four partial lower stitch areas P1 to P4, 4 is set to N.
[0032]
  In the subsequent step S6, the value of the partial under stitching area counter n is initialized to zero.
[0033]
  In step S7, a process of determining the type of partial under-sewing is performed for the first partial under-sewing area P1. Here, the process of step S7 will be described with reference to the flowchart of FIG.
[0034]
  In step S71, it is determined whether or not the partial under-sewing area P1 protrudes from the embroidery area G. Here, since the partial lower stitch region P1 does not protrude from the embroidery region G, it is determined as NO and the process proceeds to step S75.
[0035]
  In step S75, it is determined to perform normal partial undersewing for the partial undersewing region P1, and the process proceeds to step S8 in FIG.
[0036]
  In step S8, based on the determination in step S7, as shown in step S4, the self-intersection A is used as the partial lower stitching end point, and the partial lower stitching data for filling the interior of the partial lower stitching area P1 with the seam is created. To do. The partial lower stitch here is formed as a relatively coarse stitch that fills the interior of the partial lower stitch area P1.
[0037]
  In the following step S9, the value of the under stitching area counter n is incremented (n = 1), and in step S10, it is determined that n (= 1) is not equal to N (= 4) (S10, NO). The process returns to S7.
[0038]
  Next, in step S7, a process of determining the type of partial under stitching for the partial under stitch area P2 is performed.
[0039]
  That is, first, in step S71 in the flowchart shown in FIG. 4, it is determined whether or not the partial lower stitch area P2 protrudes from the embroidery area G. Here, since the partial under-sewing area P2 protrudes from the embroidery area G, it is determined YES and the process proceeds to step S72.
[0040]
  In step S72, it is determined whether or not the partial lower stitch region P2 connects partial lower stitch regions that do not protrude from other plural embroidery regions G. Here, the partial lower stitch area P2 is determined to be YES because it connects the two partial lower stitch areas P1 and P3 which do not protrude from the embroidery area G, and the process of step S74 is performed. Proceed to In the present embodiment, the partial lower sewing area P1 and the partial lower sewing area P3 are connected only through the partial lower sewing area P2, that is, the partial lower sewing area P2 is connected to the partial lower sewing area P2. P1 and the partial lower sewing area P3 are directly connected. For example, the partial lower sewing area P1 and the partial lower sewing area P3 are connected via a plurality of partial lower sewing areas including the partial lower sewing area P2. Even in a case where the partial lower stitching area P2 is indirectly connected to the partial lower stitching area P1 and the partial lower stitching area P3, in this step S72, the partial lower stitching area P2 is It is determined that the two partial lower stitch areas P1 and P3, which do not protrude from the embroidery area G, are connected, that is, YES.
[0041]
  In step S74, with respect to the partial lower stitch region P2, it is decided to perform auxiliary lower stitches for connecting the partial lower stitch region P1 and the partial lower stitch region P3 connected via P2, and the step shown in FIG. The process proceeds to S8.
[0042]
  In step S8, based on the determination in step S7, as set in step S4, the self-intersection A is the partial under-sewing start point, the self-intersection B is the partial under-sewing end point, and the partial under-sewing area P2 Auxiliary lower stitch data for connecting P1 and the partial lower stitch area P3 is created. The auxiliary lower stitching data here can be created as running stitching data at an arbitrary pitch that starts from the self-intersection A and ends at the self-intersection B and does not protrude from the embroidery region G, for example.
[0043]
  In the following step S9, the value of the under stitching area counter n is incremented (n = 2), and in step S10, it is determined that n (= 2) is not equal to N (= 4), and the process returns to step S7. .
[0044]
  Next, in step S7, a process of determining the type of partial under stitching for the partial under stitch region P3 is performed.
[0045]
  That is, first, in step S71 in the flowchart shown in FIG. 4, it is determined whether or not the partial lower stitch region P3 protrudes from the embroidery region G. Here, since the partial lower stitch region P3 does not protrude from the embroidery region G, it is determined as NO and the process proceeds to step S75.
[0046]
  In step S75, it is determined that normal partial undersewing is performed for the partial undersewing area P3, and the process proceeds to step S8 in FIG.
[0047]
  In step S8, based on the determination in step S7, as set in step S4, the self-intersection B is set as the partial lower stitch start point and the self-intersection C is set as the partial lower stitch end point. Create partial underlay data that fills with stitches.
[0048]
  In the subsequent step S9, the value of the under stitching area counter n is incremented (n = 3), and in step S10, it is determined that n (= 3) is not equal to N (= 4) (S10, NO). The process returns to S7.
[0049]
  Next, in step S7, a process of determining the type of partial under stitching for the partial under stitch region P4 is performed.
[0050]
  That is, first, in step S71 in the flowchart shown in FIG. 4, it is determined whether or not the partial lower stitch area P4 protrudes from the embroidery area G. Here, since the partial under-sewing area P4 protrudes from the embroidery area G, the determination is YES and the process proceeds to step S72.
[0051]
  In step S72, it is determined whether or not the partial lower stitch region P4 connects partial lower stitch regions that do not protrude from other plural embroidery regions G. Here, since the partial lower stitch area P4 is connected only to the partial lower stitch area P3 that does not protrude from the embroidery area G, it is determined NO, and the process proceeds to step S73.
[0052]
  In step S73, it is determined to exclude the partial lower stitch region P4 from the lower stitch target region, and the process proceeds to step S8 in FIG. The determination process in step S73 is performed based on the fact that it is not always necessary to perform under-sewing for a relatively thin area at the end of the embroidery area.
[0053]
  In step S8, based on the determination in step S7, the process proceeds to step S9 without creating partial lower stitch data for the partial lower stitch area P4, that is, without performing any process.
[0054]
  In step S9, the value of the bottom stitch area counter n is incremented (n = 4), and in step S10, it is determined that n (= 4) is equal to N (= 4) (S10, YES). Proceed to processing. Note that FIG. 6 schematically shows the state of sewing the under-sewing data created by the processing so far. The broken line in the figure represents the seam of the lower stitch.
[0055]
  In step S11, main sewing data for filling the inside of the embroidery region G is created. Since the method for creating the main sewing data here can be the same as the data creation method used in the conventional embroidery data creation processing apparatus and the like, detailed description thereof will be omitted.
[0056]
  The sewing data for performing the under stitching and the main sewing created as described above is sent to the embroidery sewing machine 25 via the output interface 18 and the communication line 20 shown in FIG. Sewing based on this is performed.
[0057]
  As described above, with respect to the partial lower stitch area where normal partial lower stitch data cannot be created, in the process of step S8, running sewing data as auxiliary lower stitch data is created, or in step S8. In processing, unnecessary under-sewing data is not created, so the user can easily obtain the necessary and sufficient under-sewing data without the crossover thread connecting the partial under-sewing areas protruding from the embroidery area. Can be created.
