Formed on fabric. At this time, since the entire embroidery pattern is larger than the embroidery frame, it is necessary to re-hold the cloth in the embroidery frame in the process of forming the plurality of divided patterns. In this way, even when sewing is interrupted between adjacent divided patterns, the boundaries are formed in a saw-tooth shape in accordance with the divided pattern data. Comparing the case where the pattern is formed with such a shape and the case where the pattern is not formed (for example, the case where the boundary is a shape along the boundary line), the latter shows that the boundary is linear and the joint is relatively clear. However, in the former case, since the boundary is saw-toothed, the boundary is stitched around and the occurrence of a clear seam is suppressed. In the case where the seam of the divided pattern is along the boundary of the adjacent divided pattern, the boundary may be separated by the seam, so that the shape does not need to be formed into a sawtooth shape.

[0031]
(Operation control means: embroidery pattern data)
The embroidery pattern data usually includes image data for displaying the form of the embroidery pattern on the liquid crystal display 51 and drive data for the frame moving means 18 for sewing the embroidery pattern on a cloth.
On the other hand, the embroidery pattern data of the embroidery pattern which is large in the whole image of the single pattern and does not fit in the embroidery frame 17 has a characteristic structure different from the above-mentioned normal pattern. The embroidery pattern data includes divided pattern data for each of the two divided patterns B1 and B2 obtained by dividing the embroidery pattern into two pieces at an intermediate portion of the pattern so as to fit in the embroidery frame 17. FIG. 3 shows the divided pattern B1, FIG. 4 shows the divided pattern B2, and FIG. 5 is an explanatory diagram showing the data structure of the divided pattern data D of the divided pattern B1. Note that the data structure of the divided pattern data of the divided pattern B2 is the same except for specific set values and the like, and therefore, the divided pattern data D of the divided pattern B1 will be mainly described.
[0032]
As shown in FIG. 5, the divided pattern data D includes control data M used for controlling the embroidery sewing operation and image data G for displaying the divided pattern B1 on the liquid crystal display 51.
The control data M is mainly a data group indicating countless needle drop positions for forming the divided pattern B1 on the cloth by embroidery sewing, that is, in order from the initial position of the sewing needle for the cloth held in the embroidery frame 17. The movement amount data group indicates the movement amount of each of the X-axis motor 26 and the Y-axis motor 28 of the frame moving means 18 for positioning the sewing needle 14 at the next needle drop position. In other words, by lowering the sewing needles 14 at predetermined positions with respect to the cloth according to the movement amount data group, countless stitches are formed, which form a plane area of a predetermined shape, and finally, the divided pattern B1 is formed. Will be done.
[0033]
Here, the shapes of the divided patterns B1 and B2 will be described. Originally, the entire shape of the embroidery pattern was a ring shape, and each of the divided patterns B1 and B2 obtained by bisecting the embroidery pattern was a half ring shape. Each of the divided patterns B1 and B2 has an overlapping area B3, B4, B5, and B6 at the boundary with the other divided pattern, and the overlapping area among the overlapping areas B3, B4, B5, and B6. In the overlapping area where the stitch direction of the embroidery formed on B3, B4, B5, and B6 intersects with the direction along the boundary (the vertical direction in FIGS. 3 and 4), the tip is directed to the other divided pattern side. It is set in a sawtooth shape. FIG. 6 is an enlarged view of an overlapping area B5 of a divided pattern B1 formed by embroidery sewing, and FIG. 7 is an enlarged view of an overlapping area B6 of a divided pattern B2 formed by embroidery sewing. As shown in the figure, in each of the divided patterns B1 and B2, the stitches are formed along the horizontal direction in the overlapping areas B5 and B6 (not shown, but the same applies to the overlapping areas B3 and B4). Intersect. Therefore, each of the overlapping regions B3, B4, B5, and B6 has a sawtooth-shaped portion.
Further, each of the divided patterns B1 and B2 is composed of first to ninth parts as a plurality of color regions partitioned for different colors. That is, each of the divided patterns B1 and B2 is composed of nine colors. Incidentally, although the tenth part is shown in the structure of the divided pattern data shown in FIG. 5, it does not form a color area but forms an alignment mark described later.
[0034]
In the movement amount data group of the control data M, the sewing needle 14 is positioned anywhere on the cloth by the movement of the embroidery frame 17 to form the divided pattern B1 in the above-described form. As described above, each of the divided patterns B1 and B2 is composed of the first to ninth parts, which are a plurality of color areas, but the number of replacements of colored embroidery threads is not increased. It is desirable to perform embroidery sewing for each color, that is, for each part. Therefore, the movement amount data group of the control data M is also divided for each part. The order in which the data processing is performed is set in advance according to the color. In the present embodiment, the processing is performed in the order of the first to ninth parts. In addition, within the division of each part
Stop command data is included for each of the sections. Such stop command data is processed after processing of all the movement amount data in the section. That is, the CPU 81, which performs control as a frame position control unit described later, processes all the movement amount data in one part, controls the operation of the frame movement unit 18, and sewes one color region of the divided pattern B1 by embroidery. Thereafter, the stop command data is processed, whereby the respective driving means involved in the embroidery sewing operation are stopped. Then, the stop can provide a user of the sewing machine with an opportunity to replace the embroidery thread used so far with an embroidery thread of a new color. Then, when the S / S switch 20 is pressed, the embroidery sewing operation is restarted again, and the operation control of the frame moving means 18 is performed based on the moving amount data of the next part.
[0035]
In addition, the processing order of the divided pattern data of each of the divided patterns B1 and B2 described above is set in advance. Here, the divided pattern data D of the divided pattern B1 is processed first. By setting the order in this manner, the respective overlapping areas B4 and B6 of the divided pattern B2 are formed so as to be stacked on the respective overlapping areas B3 and B5 of the divided pattern B1. At this time, in the overlapping area, in B6, there is an area B8 of one block separated from the color area of the ninth part so as to straddle the boundary between the divided patterns B1 and B2. Has a structure in which all the movement amount data forming the area B8 is included in the divided pattern data of the divided pattern B2 to be processed later. For this reason, the area B8 can be formed by embroidery sewing last through each of the divided areas B1 and B2, and the occurrence of chipping due to another area being overlaid on the area B8 is prevented.
[0036]
The image data G of the divided pattern data D causes the liquid crystal display 51 to display the divided pattern B1 by the processing of the CPU 81. The image data G is also divided into first to ninth parts having image data for displaying each color region, and tenth parts having image data of the alignment marks I1 and I2. It is also possible to display each part.
The alignment marks I1 and I2 are displayed while always maintaining a fixed positional relationship with the divided patterns B1 and B2. Then, the alignment marks I1 and I2 are displayed in the same position and overlapping arrangement when the divided patterns B1 and B2 are normally arranged adjacent to each other. The alignment marks I1 and I2 are formed by four dots arranged with one stitch at each vertex when the square is obliquely arranged, and the size thereof is a portion corresponding to one piece of the square. Is set to be substantially equal to the minimum stitch length, and may be a polygon such as a triangle, a pentagon, or a circle. In addition, since the alignment marks I1 and I2 are present for visually aligning the divided patterns B1 and B2, only the image data is functionally sufficient. In the present embodiment, movement amount data indicating four points is provided in the tenth part of the control data M. The movement amount data of the alignment mark I1 is set so that the processing is performed after all the movement amount data forming the divided pattern B1 have been processed. Therefore, when the embroidery sewing of the embroidery pattern is completed, a small stitch is formed at the center portion so as to connect the four points of the alignment marks I1 and I2. However, the stitch by the alignment mark I1 and the alignment mark I2 are formed. If the stitches overlap with each other without deviation, it indicates that the embroidery sewing has been performed in a state where the divided patterns B1 and B2 are also properly connected. Therefore, the embroidery sewing is performed on the alignment marks I1 and I2 for confirmation. You may go. Also, since only four stitches are sewn, removal is easy.
[0037]
Note that the control data M described above has a structure having data indicating the amount of movement of the X-axis and Y-axis motors as data indicating the needle drop position. An XY coordinate system may be set and a structure having coordinate data indicating a target needle drop position may be adopted. In that case, it is desirable to set the origin at the same position for all the divided patterns B1 and B2 and also to set the same XY coordinate system. This makes it unnecessary to visually locate and connect the divided patterns and to control the divided patterns. However, in this case, when the position of the cloth with respect to the embroidery frame 17 described later is changed, conversion processing according to the cloth position change amount is required for all coordinate data processed after the change.
[0038]
(Operation control means: CPU)
The CPU 81 uses various signals and data input based on the control program and control data written in the ROM 82 or the control data in the ROM card 84 a to perform embroidery sewing operations and various display processes on the operation panel 50. Is to be controlled.
Input signals include ON / OFF signals from an S / S switch 20, a reverse stitching switch 21 and a thread trimming switch 22, a set speed signal from a slide volume 23, a sewing machine motor 24 and a frame of the needle driving means 15 through various interfaces. The detected rotation angle signals of the encoders 29, 30, 31 provided on the X-axis / Y-axis motors 26, 28 of the moving means 18, the input position signal from the touch panel 52, and the like.
[0039]
Further, the CPU 81 stitches the embroidery frame 17 with the X-axis motor 26 and the Y-axis motor 28 of the frame moving means 18 based on the movement amount data group constituting the control data of each of the divided pattern data according to the control program. Control is performed as frame position control means for performing operation control for moving the needle to a predetermined needle drop position for each reciprocation of the up and down movement of the fourteenth movement.
Further, since the above-described divided pattern data has a structure in which the processing order is specified, the CPU 81 processes each divided pattern data in accordance with the predetermined order and controls the operation of the frame moving means 18. . Therefore, it is possible to preliminarily precede and follow the order in which the patterns are formed between the divided patterns. For example, even when a superimposed pattern is present in the overlapping area, a pattern to be sewn from the top of the pattern may be used. It is possible to avoid a situation in which the appearance is impaired by being stacked.
[0040]
In the case of sewing an embroidery pattern larger than the embroidery frame 17 described above, after forming one divided pattern B1, before embroidering the next divided pattern B2, the holding position of the cloth by the embroidery frame 17 is changed. In order to change it, it is necessary to perform re-holding. In such a case, the embroidery frame 17 is manually operated so that the temporary marking previously attached to the cloth is located immediately below the sewing needle 14, and the embroidery frame 17 is provided on the output shaft of the X-axis and Y-axis motors 26 and 28 at that time. The detected values of the encoders 30 and 31 are stored in the RAM 83, and the detected values of the encoders 30 and 31 obtained by positioning the sewing needle 14 on the temporary marking after the cloth is again held are stored in the RAM 83. The CPU 81 performs a process of storing the output values of the encoders 30 and 31 before and after the re-holding of the cloth, performs a comparison operation between the previously stored detected value before the re-holding and the detected value after the re-holding, Control is performed as a change amount calculating means for calculating a position change amount of the cloth with respect to the embroidery frame 17 caused by re-holding the cloth.
Further, in this case, the CPU 81 performs control as first position data correction means for correcting the divided pattern data of the divided pattern B2 to be subjected to embroidery sewing on the basis of the detected position change amount. Correction of the divided pattern data in this case refers to correction of preset origin position data included in the control data. Further, as described above, when coordinate data is stored in place of the movement amount data as the data indicating the needle drop position, the correction for the position change amount is performed on all the coordinate data.
Therefore, an embroidery pattern larger than the embroidery frame 17 can be easily performed by changing the holding position of the cloth and dividing the pattern into divided patterns and performing embroidery sewing.
[0041]
Further, as will be described later, the CPU 81 corrects the position of the image of each divided pattern B1 and B2 by an external operation on the display image of each divided pattern B1 and B2 displayed on the liquid crystal display 51 by the control program. Control is performed as second position data correction means for correcting each divided pattern data based on the relative positional relationship between the divided patterns B1 and B2 displayed on the liquid crystal display 51 by the correction. Correction of the divided pattern data in this case refers to correction of preset origin position data included in the control data. Further, as described above, when coordinate data is stored in place of the movement amount data as the data indicating the needle drop position, the correction for the position change amount is performed on all the coordinate data.
The image position correcting means for correcting the position of the image of each of the divided patterns B1 and B2 is realized by the multi-directional arrow keys and the touch panel 52 displayed together with each of the divided patterns B1 and B2 on the liquid crystal display 51. .
With the above configuration, it is possible to visually connect the divided patterns B1 and B2 with high accuracy.
In addition, the CPU 81 also performs control as a display control unit that can increase the display magnification of the display image of each of the divided patterns B1 and B2 based on the image data of each of the divided pattern data on the liquid crystal display 51. Therefore, it becomes possible to perform the positioning of each divided pattern more precisely.
[0042]
(Operation explanation of embroidery sewing machine)
Next, a sewing method for sewing an embroidery pattern of a size that does not fit in the embroidery frame 17 in the sewing machine 10 will be described. 8 and 9 are operation flowcharts of the sewing machine 10, and FIGS. 10 to 29 are display examples of the operation panel 50.
[0043]
First, in order to embroider an embroidery pattern of a size that does not fit in the embroidery frame 17, when a switch for switching to the large embroidery pattern embroidery mode is input on an operation screen (not shown) displayed on the liquid crystal display 51, the flag F is set. The process of resetting both the part counter C and the counter C to 0 is performed by the operation control means 80 (step S1).
[0044]
Next, the operation control means 80 displays the large connecting pattern selection screens P1 and P2 (FIGS. 10 and 11) on the operation panel 50 (step S2). On the large connecting pattern selection screens P1 and P2, images of the divided patterns B1 and B2 obtained by dividing the large connecting pattern in the middle area in the vertical direction are displayed. Each of the display images of the divided patterns B1 and B2 is a switch on the touch panel 52, and can be selected in order.
FIG. 10 shows a case where the divided pattern B1 is selected, in which case the selected divided pattern R is displayed in the upper part of the screen. FIG. 11 shows a case where the divided pattern B2 is selected next. In this case, the selected divided image L is displayed adjacent to the right of the divided image R in the upper part of the screen.
The operation control means 80 performs the display control and stores which divided pattern is to be subjected to the embroidery sewing by the selection operation (step S3).
[0045]
Next, the operation control means 80 displays the embroidery frame selection screen P3 (FIG. 12) on the operation panel 50 (step S4). On the embroidery frame selection screen P3, a large, medium, and small embroidery frame selection switch W1 is displayed in the middle right area in the vertical direction, and the operation control unit 80 recognizes the selected embroidery frame via the touch panel 52. In the middle left area of the embroidery frame selection screen P3, the divided patterns B1 and B2 are displayed within the embroidery range of the selected embroidery frame, and the embroidery range and the size of each of the divided patterns B1 and B2 are displayed. This allows comparison and encourages the selection of an accurate embroidery frame. In the case where there are two divided patterns, as shown in the figure, one of the divided patterns is displayed as a silhouette, and the size of each divided pattern and the size of the embroidery frame can be compared while overlappingly displayed. If the number of divided patterns is larger, a silhouette display of a different color may be displayed for each divided pattern.
Then, the operation control means 80 is in a state of waiting for selection of an embroidery frame, and when selection and confirmation are input, stores which embroidery frame is selected (step S5). The embroidery frame may be determined by switching the confirmation switch after the embroidery frame selection switch W1 is input, or by re-entering the same embroidery frame of the embroidery frame selection switch W1. Is also good.
[0046]
Next, the operation control unit 80 displays the editing screen P4 (FIGS. 13, 14, and 15) on the operation panel 50 (step S6). In the editing screen P4, the divided patterns B1 and B2 are displayed in the middle left area in the vertical direction, and the divided pattern moving operation keys W4, the display magnification selection switch W3, and the editing switch W2 are displayed in the middle left area in the vertical direction from the top. Is provided.
The user of the embroidery sewing machine 10 moves one of the divided patterns B1 and B2 with the divided pattern moving operation key W4 while observing the divided patterns B1 and B2 displayed on the display section of the editing screen P4. It is possible to perform an operation of overlapping the respective alignment marks on the display unit (step S7). At this time, the interval L between the alignment marks I1 and I2 is detected by the operation control means 80. The display screen of the display unit can be enlarged and displayed by the display magnification selection switch W3 as needed (step S8), and the magnification can be selected from 1, 2, 4, and 8 times. . The operation control 80 waits for the input of the display magnification selection switch W3. If there is no input, the process returns to step S7 to return to the state of accepting the positioning operation, and if there is an input of the display magnification selection switch W3, it responds to the selected magnification. An enlarged display control is performed (step S9).
[0047]
FIGS. 14 and 15 show a state where the alignment marks I1 and I2 are visually displayed by selecting the enlarged display of 8 times, and FIG. 15 further shows each alignment mark I1 by operating the division pattern moving operation key W4. , I2 are superimposed. When the user of the sewing machine 10 inputs the confirmation of the positioning, the operation control unit 80 calculates the interval L between the respective positioning marks I1 and I2 from the positions of the positioning marks I1 and I2 on the screen. Are stored in the RAM 83 (step S10).
[0048]
Next, the operation control means 80 displays a sewing pattern selection screen P5 (FIG. 16) on the operation panel 50 (step S11). On the sewing pattern selection screen P5, the divided patterns B1 and B2 and the virtual embroidery frame E are displayed in the middle left area in the vertical direction, and divided by the embroidery frame moving operation key W5 provided in the middle left area in the vertical direction. The selection of the patterns B1 and B2 is accepted (step S12). The user of the sewing machine 10 moves the virtual embroidery frame E using the embroidery frame moving operation key W5 and positions the virtual embroidery frame E to the divided pattern to be selected. In this case, the division pattern B1 is selected. Then, the OK switch H is input. At this time, it is convenient for the user to display on the screen a description and an image for instructing the divided pattern for moving the embroidery frame to be B1.
[0049]
When the selection of the divided pattern B1 is completed, the operation control means 80 displays the cloth holding command screen P6 (FIG. 17) on the operation panel 50 (step S13). In response, the user of the sewing machine 10 sets the cloth on the embroidery frame 17. At this time, a cross line is previously written on the cloth as temporary marking with chalk or the like. At this time, the intersection of the crosshairs is arranged to be closer to the other divided pattern B2 with respect to the selected divided pattern B1. A cloth is set and held on the embroidery frame at the position where the divided pattern B1 is sewn on the crosshair. When the embroidery frame 17 is mounted on the frame moving means 18, the user of the sewing machine 10 inputs an OK switch G.
[0050]
Next, the operation control means 80 displays the embroidery frame origin input acceptance screen P7 (FIGS. 18, 19, 20) on the operation panel 50 (step S14). On the embroidery frame origin input acceptance screen P7, the user of the sewing machine 10 inputs the origin position to the operation control means 80 using the intersection of the crosshairs attached to the cloth as the origin. Therefore, any two points along the vertical line of the cross hair are positioned on the sewing needle 14, and any one point along the horizontal line is positioned on the sewing needle 14.
[0051]
On the embroidery frame origin input reception screen P7, an input instruction screen is displayed in the upper part of the vertical direction, the selected divided pattern B1 is displayed in the middle left part of the vertical direction, and the embroidery frame is displayed in the middle left part of the vertical direction from the top. An embroidery frame moving operation key W6 for moving the cursor 17 and a decision switch W7 for inputting which of three points with respect to the cross line the positioning has been performed are provided. Further, FIG. 18 shows an embroidery frame origin input accepting screen P7 when inputting the first point along the vertical line of the crosshair, and FIG. 19 shows the input screen for inputting the second point along the vertical line of the crosshair. FIG. 20 shows the embroidery frame origin input reception screen P7 when the first point along the horizontal line of the cross hair is input.
[0052]
The user of the sewing machine moves the embroidery frame 17 with respect to the sewing needle 14 using the embroidery frame moving operation key W6, sequentially positions three points with respect to the cross line, and selects and inputs the decision switch W7.
On the other hand, the operation control means 80 detects the outputs of the encoders 30 and 31 when the embroidery frame 17 is positioned with respect to the sewing needle 14 and stores the outputs in the RAM 83. Further, the three positions of the three points are obtained from the outputs of the encoders 30 and 31 at the recorded points, and the intersection position of the cross line (the origin of the embroidery frame) is calculated from these positions and stored in the RAM 83 (step S15). .
[0053]
Next, the operation control means 80 displays the sewing screen P8 (FIG. 21) on the operation panel 50 (step S16). In the sewing screen P8, the entire image of the currently selected divided pattern B1 is displayed on the uppermost leftmost and middle left sides in the vertical direction. In the second and subsequent parts from the upper left side in the vertical direction, three parts are displayed side by side in the order in which embroidery sewing will be performed. On the left side of the middle part, the time for the sewing place and the type of the selected embroidery frame are displayed.
[0054]
In the state where the sewing screen P8 is displayed, the operation control means 80 detects the presence or absence of an input of the S / S switch 23 (step S17). If there is no input, the detection is continued, and the user of the sewing machine 10 proceeds to step S17. When the / S switch 23 is input, 1 is added to the parts counter C (step S18).
Further, it is confirmed whether or not the flag F is 1 (step S19). If F = 1, the embroidery frame origin position is corrected for the interval L between the two alignment marks I1 and I2 stored in step 10 (step S20). However, since the flag F is not added unless the embroidery sewing is completed for one divided pattern B1, the origin position correction is performed when the embroidery sewing shifts from the divided pattern B1 to the divided pattern B2.
[0055]
If the flag F is not 1, the operation control means 80 starts embroidery sewing according to the order of parts (step S21). That is, with the origin position of the embroidery frame 17 calculated in step S15 as a start position, the moving amount data in the first part of the control data of the divided pattern data of the divided pattern B1 is sequentially processed, and operation control is performed based on this. The means 80 constantly positions the sewing needle at a predetermined needle drop position by controlling the operation of the frame moving means 18 in accordance with the vertical movement of the sewing needle 14, and processes all the movement amount data of the first part. Then, the drive of the frame moving means 18 and the sewing machine motor 24 is stopped by the stop command data, and the thread trimming solenoid 19 is driven to cut the embroidery thread (step S22).
[0056]
The operation control means 80 checks whether or not the parts counter C = 10. With this confirmation, it is determined whether or not all the parts of the divided pattern B1 have been sewn (step S23). When the parts counter C is less than 10, the operation control means 80 updates the next three parts images in the upper and lower stages of the sewing screen P8 on which embroidery sewing is to be performed (step S24). Then, the process returns to step S17, and enters an input waiting state of the S / S switch 20. During this time, the user of the sewing machine 10 changes the embroidery thread and inputs the S / S switch 20. Thus, the processing of steps S17 to S23 is repeated until the embroidery sewing of all parts is completed.
[0057]
FIG. 22 shows a sewing screen P8 in a state where the embroidery sewing of each part is almost completed for the divided pattern B1. Thereafter, embroidery sewing of all parts is completed. If it is determined in step S23 that the parts counter C is 10, the embroidery sewing of the divided pattern B1 is completed, and 1 is added to the flag F. Further, the parts counter is reset to 0 (step S25).
[0058]
Next, the operation control means 80 displays a continuation instruction input screen (not shown) on the liquid crystal display 51, and waits for an input as to whether or not to shift the processing to the next divided pattern (step S26). At this time, if it is selected not to shift the processing, the operation control means 80 displays a confirmation screen as to whether or not to end the processing on the liquid crystal display 51, and waits for an input as to whether or not to end the processing (step S27). If "end" is selected, all the processing is ended, and if "do not end" is selected, the process returns to step S25 to wait again for input as to whether or not to shift the processing to the next divided pattern.
[0059]
Further, in step S25, when the selection to shift the processing to the next divided pattern is performed, the process returns to step S11, and the sewing pattern selection screen P5 (FIG. 23) is displayed. When the user of the sewing machine 10 selects the divided pattern B2 (Step S12), the cloth holding command screen P6 (FIG. 24) is displayed (Step S13). Then, when the cloth is held again in the embroidery frame 17, the embroidery frame origin input acceptance screen P7 (FIGS. 25, 26, 27) is displayed. The user of the sewing machine again performs the positioning of the three points with respect to the initial crosshair, and the operation control means 80 calculates and stores the origin position of the crosshair (steps S14 and S15).
[0060]
Then, the sewing screen P8 (FIG. 28) is displayed (Step S16), and when the user of the sewing machine 10 inputs the S / S switch (Step S17), 1 is added to the parts counter C (Step S18). . Then, it is confirmed whether or not the flag F is 1 (step S19). At this time, since F = 1 has already been added for the processing of the divided pattern B2, the origin position corresponding to the interval L between the alignment marks I1 and I2 stored in step S10 is corrected (step S20). . If the positioning of the positioning marks I1 and I2 has been performed with sufficient accuracy in step S7, L is almost zero, and the origin position of the embroidery frame 17 is hardly corrected.
[0061]
Then, the operation control means 80 starts embroidery sewing according to the order of the parts (step S21). The drive is stopped every time one part is completed (step S22), thread replacement is performed, and the sewing screen P8 shifts from the state of FIG. 28 to the state of FIG. 29 as the sewing of each part progresses. When the embroidery sewing of all the parts is completed (step S23), the parts counter is reset (step S25), and it is confirmed whether or not the next divided pattern is selected (step S26). After confirmation (step S27), the entire process is completed.
[0062]
As described above, the operation control of the sewing machine 10 is performed, and various data are processed, so that the joint embroidery can be favorably performed on an embroidery pattern having a size that does not fit in the embroidery frame 17. That is, an overlapping area provided at both boundaries of the two divided patterns obtained by dividing the embroidery pattern into two, and an overlapping area where the seam of the overlapping area intersects with the boundary line is divided into the other divided areas. Since the operation control means 80 of the sewing machine 10 controls the operation of the frame moving means 18 based on the divided pattern data having a saw-toothed data structure with the tip directed to the pattern side, each divided pattern after embroidery sewing is sewn. The borders are serrated along the seam, and no seams cross the seam. Therefore, even in the case of performing joint embroidery for each divided pattern for an embroidery pattern of a size that does not fit in the embroidery frame, embroidery sewing of a good finish is performed, which is comparable to the case where embroidery is performed integrally. It becomes possible.
[0063]
In addition, the case where the size of the single embroidery pattern is larger than the size of the embroidery frame has been described. However, the present invention is not limited to this. For example, even when the embroidery pattern is a combination of two or more small patterns and the pattern is larger than the embroidery frame, one or more small patterns are associated with the pattern. In the middle part, all of the patterns may be divided into a size that can be accommodated in the embroidery frame, and a plurality of divided patterns may be formed.
[0064]
