【Example】
Hereinafter, the present invention will be described in detail with reference to the drawings.
The appearance of the embroidery sewing data creation device of the present invention is shown in FIG. 10 and is the same as the conventional one . First, the hardware configuration of the embroidery sewing data creation device will be described with reference to FIG.
[0014]
In the figure, reference numeral 20 denotes an image scanner as an example of an image reading device. Reference numeral 30 denotes an original picture on which arbitrary designs, characters, and the like are drawn. 40 is a central processing unit (hereinafter abbreviated as CPU), 44 is embroidery sewing data storage means, 45 is each data storage means (RAM), and 46 is program storage means (ROM). Next, 25 is a liquid crystal display unit, and 48 is a display unit control means. A data bus 47 electrically connects the above-described devices to one another. The embroidery sewing data storage means 44 corresponds to the RAM card 18 in FIG.
[0015]
Next, FIG. 4 shows a functional block diagram illustrating main operations of FIG.
[0016]
In the figure, 41 is image data storage means, 42 is data processing means, 43 is processing data storage means, and 43a is embroidery data conversion means.
[0017]
Further, the image data storage unit 41 and the processed data storage unit 43 in FIG. 4 correspond to each data storage unit 45 in FIG. The data processing unit 42 and the embroidery data conversion unit 43a in FIG. 4 correspond to the processing program of the program storage unit 46 and the CPU 40 in FIG. 3 and 4 in the following drawings are the same or equivalent.
[0018]
The present invention is characterized in that the function of the embroidery data conversion means 43a is improved, and an embodiment will be described below in detail. FIG. 1 is a functional block diagram for explaining the function of the embroidery data conversion means 43a.
[0019]
In the drawing, reference numeral 1 denotes a mode selecting means for selecting once sewing or block sewing, 2 a block sewing determining means, and 3 a block number counting means. 4 is a stitch data inclination determining means, 5 is image data → stitch data converting means, 5a is a conversion end signal sent from the image data → stitch data converting means 5 to the counting means 3 and the stitch data inclination determining means 4. is there. Reference numeral 6 denotes a stitch data storage unit, which corresponds to the embroidery data storage unit 44.
[0020]
Next, a schematic operation of the embroidery sewing data creating device 24 having the above-described configuration will be described with reference to a flowchart of FIG. Note that Sn (n = 1, 2, 3,..., 16) in FIG. 2 indicates a step of each processing.
[0021]
First, the RAM card 18 is inserted into the card writer section 27 (see FIG. 10) of the embroidery sewing data creation device 24, and the mode is selected by the operation key section 26 (step S1). Next, when the block sewing is selected (Yes at Step S2), the counters T1 and T2 of the block number counting means 3 are cleared (Step S4). Note that when step S2 is negative, the process once proceeds to the sewing process (step S3), but since this is not related to the present invention, the description is omitted.
[0022]
Here, the block sewing means reading an original pattern of one pattern for each block composed of one or a plurality of pattern elements constituting the original pattern, so that the blocks can be sewn independently. For example, in the tulip pattern of FIG. 7, stitch data of each block of three petals, stems, leaves, and the like can be separately created, and the color of the embroidery thread can be changed for each of these blocks to sew. .
[0023]
In response to an input from the operation key unit 26, the embroidery sewing data creation device 24 enters the input mode, and a message such as "Press the reading start button of the image scanner." Is displayed on the liquid crystal display unit 25, for example.
[0024]
Thereafter, image reading is performed while pressing the reading start button 22 of the image scanner 20 (step S5). With this operation, the read image data is stored in the image data storage unit 41 (step S6). When this reading is completed, the reading of one block of the original image pattern is completed, so that the block number counting means 3 (see FIG. 1) counts one block of the image data (step S7).
[0025]
Next, it is determined whether reading of all blocks of the original image pattern has been completed (step S8). When the reading is completed (Yes at Step S8), the process proceeds to Step S9. If the reading is not completed (No at Step S8), the process returns to Step S5, and the process up to Step S8 is repeated until the result at Step S8 becomes affirmative, and the original image is read and the number of blocks is measured.
[0026]
When the reading is completed, the inclination of the stitch is initialized to θ = θ O (step S9). Next, the reference axis for creating the stitch data is inclined by θ O with respect to the X axis (step S10). After the above processing, the image data is converted into stitch data by the conversion means 5 (step S11), and the stitch data is stored (step S12). At this time, the block counting means 3 counts up by one (step S13).
[0027]
Next, it is determined whether or not the sewing data conversion has been completed (step S14). This determination is affirmative when the counter values T1 and T2 become equal, and the process proceeds to step S16. When step S14 is negative, the process proceeds to step S15. Note that the counter T2 may not be used, and the counter value T1 may be decremented by one in step S13, and if the counter value becomes 0 in step S14, the process may proceed to step S16.
[0028]
In the step S15, the seam data inclination determining means 4 adds a constant value θA to the stitch inclination θ (step S15). Thereafter, the process returns to step S10, and repeats until step S14 becomes affirmative.
[0029]
When the conversion of the stitch data is completed, the stitch data is stored and registered in the stitch data storage means 6 (step S16).
[0030]
With the step S16, the general operation of the embroidery sewing data creation device 24 completes one cycle and ends.
[0031]
As described above, the RAM card 18 in which the embroidery stitch data is stored and registered by the embroidery sewing data creating device 24 is inserted into the data reading card reader unit 15 (see FIG. 11) of the embroidery sewing machine 10, and the RAM card 18 The data is read, and the embroidery sewing machine 10 is operated.
[0032]
FIG. 11 is a perspective view of an embroidery sewing machine that uses data created by the embroidery sewing data creation device of the present invention. In the figure, 11 is a start / stop key for starting and stopping the embroidery sewing machine, 12 is a liquid crystal display, 16 is an embroidery frame for holding an embroidery cloth, and 17 is a front panel of the embroidery sewing machine.
[0033]
In the above-described embodiment, the fixed angle θA is added in step S15. However, the present invention is not limited to this, and a different angle may be added for each block, or the seam may be added in advance. May be prepared in advance, and these may be sequentially used.
[0034]
Next, a description will be given of a specific example in which the present invention is applied to an original image pattern having four blocks obtained by dividing a circular pattern into four as shown in FIGS. Here, FIG. 5 shows an embroidery pattern obtained by the method of the present invention, and FIG. 6 shows an embroidery pattern in the conventional method.
[0035]
In FIG. 5, reference numeral 70 denotes a pattern element to be embroidered, and reference numerals 71a, 72a, 73a, and 74a denote pattern elements divided for each block. Reference numerals 71b, 72b, 73b and 74b are embroidery eyes of the pattern element. 75 is a boundary. θ1, θ2, and θ3 are the inclination angles of the stitches added for each element. Therefore, assuming that the inclination of the stitch of the pattern element 71a is θ (= 0 °), the inclination of the stitch of the pattern element 72a is θ + θ1, and the inclination of the stitch of the pattern elements 73a and 74a are θ + θ1 + θ2 and θ + θ1 + θ2 + θ3.
[0036]
On the other hand, the inclination angles of the conventional embroidery stitches 61a, 62a, 63a, 64a are all the same θ. Here, 61a, 62a, 63a, and 64a are pattern elements divided for each block, and 65 is a boundary.
[0037]
As is clear from the above description, in the embroidery pattern of FIG. 5, since the inclination angle of the stitch differs for each block, the boundaries of the pattern elements become clear and the pattern has a three-dimensional effect. On the other hand, in the embroidery pattern shown in FIG. 6, since the pattern elements are sewn in the same direction, the boundary 65 is not clear, so that the appearance of the sewn up is not very good and the three-dimensional appearance is poor.
[0038]
Next, the embroidery pattern of the tulip pattern element 80 created according to the present invention will be described with reference to FIG.
[0039]
In the figure, 81a, 82a, 83a and 84a are pattern elements divided into blocks, respectively. 81b, 82b, 83b and 84b are embroidery eyes of the pattern element.
[0040]
Here, the inclination of the first embroidery stitch 81b is the initial value θ of the inclination determination means 4 of the stitch. The inclination of the second, third, and fourth embroidery stitches 82b, 83b, 84b is the inclination obtained by adding θA to the inclination θ of the embroidery stitch 81b.
[0041]
As is clear from each of the above application examples, the embroidery pattern obtained by applying the present invention is inclined by a certain angle for each block. As a result, the boundary of the pattern where the pattern elements are continuous is clear, and the appearance of the finished sewing is improved. Also, the sewn pattern gives a three-dimensional effect.
[0042]
Although the embroidery sewing data creation device 24 of the above embodiment has an independent configuration, the embroidery sewing data creation device 24 may be built in the embroidery sewing machine main body 10 (see FIG. 11).
[0043]
【The invention's effect】
As is clear from the above description, according to the present invention, when block sewing is selected, an embroidery pattern whose direction changes automatically for each block can be obtained. As a result, there is an effect that the boundary of the pattern where the pattern elements are continuous is clear, the appearance of the finished sewing is improved, and the finished sewing pattern has a three-dimensional effect.
