The display area AR1 is an area in which the sewing lines are sequentially displayed in sewing line units in accordance with the sewing order. SSk and SEk (k = 1, 2,...) In the figure are the start and end points of each sewing line, respectively. The sewing device 20 starts sewing from a start point, and cuts a sewing thread at an end point to sew one sewing line. SS0 is a sewing start point. In particular, when the distinction is not necessary, the start point and the end point are respectively referred to as SS and SE. The solid line between SSk and SEk indicates a sewing line, and the actual sewing line includes a plurality of needle drop points. An alternate long and short dash line is a virtual line indicating a movement locus when the position of the needle drop point moves without the sewing needle of the sewing machine being stuck in the cloth. Hereinafter, a screen constituted by the menu bar, the command bar, the display area AR1 and the like will be referred to as a main screen. The positions of the arrangement of the menu bar, the command bar, and the display area AR1 may be arbitrary.

  In the example of FIG. 3, the display unit 14 superimposes and displays the sewing order display screen on the main screen. Specifically, the sewing order display screen is displayed near the right end in the display area AR1. In the example of FIG. 3, the sewing order display screen arranges the first sewing order reproduction button RSB1 at the lower left portion, and arranges the first progress bar PB1 at the right side of the first sewing order reproduction button RSB1. The first sewing order reproduction button RSB1 is a button for sequentially displaying the sewing lines in the sewing area in the display area AR1 in accordance with the sewing order specified by the sewing data. The first progress bar PB1 moves in accordance with the display of the sewing line. As in the example of FIG. 3, for example, when the number of sewing lines is six, six movements are performed in synchronization with the progress of the display of the sewing lines to reach the final position on the right from the start position on the left.

<Automatic sewing order setting screen AS>
FIG. 4 is an example of the automatic sewing order setting screen AS. As shown in FIG. 4, the automatic stitching order setting screen AS includes a field of "sewing method", a field of "distance", and a field of "angle". Each "sewing method" is associated with "distance" and "angle" respectively. The "sewing method" is the name of each algorithm for setting the sewing order. The “distance” indicates the sum of the movement distance L (unit: mm) of the optimum sewing order calculated by the corresponding algorithm. "Angle" indicates the sum of the movement angle θ (unit: rad) of the optimum sewing order calculated by the corresponding algorithm, and displays a value obtained by converting the sum of the calculated movement angle θ into a frequency. The automatic sewing order setting screen AS arranges the second sewing order reproduction button RSB2 and the second progress bar PB2 on the lower side, and the continuation button B1 on the lower side of the second sewing order reproduction button RSB2 and the second progress bar PB2.

Button. The second progress bar PB2 moves in accordance with the display of the sewing line. As in the example of FIG. 3, for example, when the number of sewing lines is six, six movements are performed in synchronization with the progress of the display of the sewing lines to reach the final position on the right from the start position on the left. The continue button B1 is a button for reflecting the sewing order of the selected sewing method on the sewing data. For example, when the operator selects the first overall (fixed) sewing method and selects the continue button B1, the CPU 11 changes the sewing order of the sewing data to the first overall (fixed) sewing order. The cancel button B2 is a button selected when the sewing order designated by the sewing data is not changed.

<Movement angle θ>
The movement angle θ will be described with reference to FIG. The movement angle θ (0 ≦ θ ≦ π) is a virtual line (dotted line in the figure) obtained by extending from the end point SE1 a line connecting one hand before the end point SE1 and the end point SE1 among the sewing lines from the start point SS1 to the end point SE1. , An angle formed by a line segment (dashed-dotted line in the drawing) connecting the end point SE1 and the start point SS2 of the next sewing line. That is, the movement angle θ is a change amount of the movement direction of the feed mechanism of the sewing device 20 when the sewing device 20 moves to the start point SS2 after sewing the end point SE1.

<Setting the sewing order of the sewing method>
The sewing method is an algorithm for setting the sewing order as described above, and is a condition for setting the sewing order. An algorithm corresponding to each sewing method will be described. In order to simplify the explanation, the sewing lines are made into three stitch lines a, b and c, and each algorithm is described. (A, b, c) means processing in the order of sewing lines a, b, c. The movement angle θ of the sewing lines a and b is referred to as θ (a, b). The sewing method of this specific example is: distance priority (fixed), distance priority (start stitch line change), angle priority (fixed), angle priority (start stitch line change), first general (fixed), first general (start) Sewing line change), second total (fixed), second total (head stitch line change).

<Distance priority (fixed)>
In the distance priority (fixed), the sewing order of the first sewing line a specified by the sewing data is fixed. The CPU 11 sets a sewing line having a starting point SS at which the moving distance L between the sewing line b and the respective starting points SSb and SSc of the sewing line c is minimum from the end point SEa of the sewing line a to the next sewing line. For example, when the movement distance L (a, c) from the end point SEa to the start point SSc 迄 is shorter than the movement distance L (a, b) from the end point SEa to the start point SSb 迄, the CPU 11 sews the next sewing order of the sewing line a. Set sewing line c as a line. At this time, the sewing order is (a, c, b). The movement distance L (a, b) can be obtained by the following calculation formula (Equation 1). Na in the equation is the needle drop point of the sewing line a. xa (Na-1) and ya (Na-1) are the x-coordinate and y-coordinate, respectively, of the end point SEa of the sewing line a. xb (0) and yb (0) are the x-coordinate and y-coordinate, respectively, of the start point SSb of the sewing line b. The movement distance L (a, c) or the like can be similarly calculated by the calculation formula.

  At this time, the CPU 11 sets (a, c, b) as the distance priority (fixed) sewing order, and the “distance” corresponding to the distance priority (fixed) in the “sewing method” of the automatic sewing order setting screen AS. The total of the movement distance L in the sewing order (a, c, b) is displayed in the field. The sum of the movement distances L is the sum of the movement distances L (a, c) and the movement distances L (c, b). The CPU 11 calculates the sum of the movement angles θ of the set sewing order (a, c, b), and in the “angle” column corresponding to the distance priority (fixed) in the “sewing method” of the automatic sewing order setting screen AS. The sum of the calculated movement angles θ may be displayed. The sum of the movement angles θ is the sum of the movement angles θ (a, c) and the movement angles θ (c, b). When the operator selects distance priority (fixed), the CPU 11 sets the sewing order of the shortest movement distance L without changing the first sewing line. Therefore, since the time taken for the sewing process of the sewing device 20 can be shortened, the operation efficiency of the sewing device 20 is improved.

<Depth priority (leading stitch line change)>
In the distance priority (leading sewing line change), the sewing order of the first sewing line a designated by the sewing data can be changed. The CPU 11 sets each sewing line a, b, c as the first sewing line, and finds a sewing order in which the total of the movement distance L is the smallest. The CPU 11 sets a sewing order in which the total movement distance L is the smallest among the determined sewing orders. For example, the sum of the movement distances L when the sewing sequence with the smallest sum of the movement distances L when the sewing line a is the first sewing line is (a, c, b) and the sewing line b is the first sewing line Assume that the sewing order with the smallest sewing order is (b, c, a) and the total of the movement distances L when the sewing line c is the first sewing line is (c, a, b). At this time, the CPU 11 sets a sewing order in which the sum of the movement distances L is the smallest among the three sewing orders in the sewing order of the distance priority (leading stitch line change). The CPU 11 displays the sum of the movement distance L of the set sewing order in the "distance" column corresponding to the distance priority (top stitching line change) in the "sewing method" of the automatic sewing order setting screen AS. The CPU 11 calculates the sum of the movement angles θ of the set sewing order, and the calculated movement in the “angle” column corresponding to the distance priority (top sewing line change) in the “sewing method” of the automatic sewing order setting screen AS. The sum of the angles θ may be displayed.

  When the operator selects distance priority (leading stitch line change), the CPU 11 sets the sewing order of the shortest movement distance L in a state where the sewing order can change the first sewing line. The movement distance L may be shorter than the distance priority (fixed) depending on the sewing order. Therefore, since the time taken for the sewing process of the sewing device 20 can be further shortened, the operation efficiency of the sewing device 20 is further improved.

<Angle priority (fixed)>
In the angle priority (fixed), the sewing order of the first sewing line a specified by the sewing data is fixed. Among the sewing lines a, the virtual line obtained by extending the end point SEa from the end point SEa, and the start point SSb of the sewing line b and the start point SSc of the sewing line c from the end point SEa The movement angles θ (a, b) and θ (a, c) with the connecting line segment are calculated respectively. The CPU 11 sets the sewing line having the smaller movement angle θ as the next sewing line among the movement angles θ (a, b) and θ (a, c). For example, when the movement angle θ (a, b) is smaller than the movement angle θ (a, c), the CPU 11 sets the sewing line b as the next sewing line. At this time, the sewing order is (a, b, c). The movement angle θ (a, b) can be obtained by the following calculation formula (Equation 2). The movement angle θ (a, c) or the like can be calculated by the same calculation formula.

  At this time, the CPU 11 sets (a, b, c) as the angle priority (fixed) sewing order, and the “angle” corresponding to the angle priority (fixed) in the “sewing method” of the automatic sewing order setting screen AS. In the column, the total of the movement angles θ of the sewing order (a, b, c) is displayed. The sum of the movement angles θ is the sum of the movement angles θ (a, b) and the movement angles θ (b, c). The CPU 11 calculates the sum of the moving distances L of the set sewing order (a, b, c), and in the "distance" column corresponding to the angle priority (fixed) in the "sewing method" of the automatic sewing order setting screen AS. The sum of the calculated movement distances L may be displayed. When the operator selects angle priority (fixed), the CPU 11 sets the sewing order of the shortest movement angle θ without changing the first sewing line. Therefore, since the load applied to the feed mechanism (in particular, the feed motor) can be reduced when the moving direction of the feed mechanism changes, the durability of the sewing device 20 is improved.

<Angle priority (start stitch line change)>
In the angle priority (start stitch line change), the sewing order of the first sewing line a designated by the sewing data can be changed. The CPU 11 sets each sewing line a, b, c as a first sewing line, and finds a sewing order in which the sum of the movement angles θ is the smallest. The CPU 11 sets a sewing order in which the sum of the movement angles θ is the smallest among the determined sewing orders. For example, the sum of the movement angles θ when the sewing sequence with the smallest sum of the movement angles θ when the sewing line a is the first sewing line is (a, c, b) and the sewing line b is the first sewing line Assume that the smallest sewing order is (b, a, c), and the total sewing angle θ when the sewing line c is the first sewing line is (c, a, b). At this time, the CPU 11 sets a sewing order in which the sum of the movement angles θ is the smallest among the three sewing orders in the sewing order of the angle priority (leading stitch line change). The CPU 11 displays the total of the set movement angles θ of the sewing order in the “angle” column corresponding to the angle priority (head stitch line change) in the “sewing method” of the automatic sewing order setting screen AS. The CPU 11 calculates the sum of the movement distance L of the set sewing order, and calculates the movement distance calculated in the "distance" column corresponding to the angle priority (start stitch line change) in the "sewing method" of the automatic sewing order setting screen AS. You may display the sum of L.

  When the operator selects the angle priority (leading sewing line change), the CPU 11 sets the sewing order of the shortest movement angle θ in a state where the first sewing line can be changed. The movement angle θ may be smaller than the angle priority (fixed) depending on the sewing order. Therefore, since the load applied to the feed mechanism (in particular, the feed motor) can be further reduced when the moving direction of the feed mechanism changes, the durability of the sewing device 20 is further improved.

<First comprehensive (fixed)>
In the first overall (fixed), the sewing order of the first sewing line a specified by the sewing data is fixed. The CPU 11 calculates movement distances L (a, b), L (a, c), movement angles θ (a, b), θ (a, c), respectively. The CPU 11 sets a sewing line having a smaller value Lθ1 obtained by the following calculation formula (Equation 3) in the next sewing order. "0.1" in the equation is a weight. If there is no weight, when the sum of the movement angles θ is 0, the calculation result is “0” no matter how long the movement distance L is. In this case, Lθ1 is smaller than in the case where the total movement angle θ is larger than 0 but the movement distance L is short. Therefore, since the CPU 11 sets the next sewing order regardless of the movement distance L when the total movement angle θ is zero, it is not possible to set an appropriate sewing order. The weight may not be "0.1", and may be a small value so as not to cancel out the influence of the difference of the sum of the movement angles θ. Lθ 1 (a, c) and the like can also be calculated by the same calculation formula.

  For example, when the value of Lθ 1 (a, c) is smaller than L θ 1 (a, b), the CPU 11 sets the sewing order (a, c, b) as the first total (fixed) sewing order . The CPU 11 displays the sum of the movement distance L of the set sewing order and the sum of the movement angle θ in the corresponding "distance" column and the "angle" column in the "sewing method" of the automatic sewing order setting screen AS. . When the operator selects the first total (fixed), the CPU 11 sets an optimal sewing order in consideration of both the movement distance L and the movement angle θ without changing the first sewing line. Therefore, both the operation efficiency and the durability of the sewing device 20 can be improved because the time required for the sewing process can be shortened and the load applied to the feed mechanism (especially the feed motor) can be reduced when the moving direction of the feed mechanism changes. .

<First overall (leading sewing line change)>
In the first total (leading sewing line change), the sewing order of the first sewing line a designated by the sewing data can be changed. The CPU 11 sets each sewing line a, b, c as the first sewing line, calculates the movement angle θ and the movement distance L, respectively, and sews the next sewing line for which the value Lθ1 is smaller according to the formula 3 As the order, each sets the sewing order. For example, when the set sewing order is (a, c, b), (b, c, a), (c, a, b), the CPU 11 sets Lθ 1 (a, c, b) and Lθ 1 (b, c). , A) and Lθ 1 (c, a, b), the sewing order having the smallest value is set to the sewing order of the first general (leading stitch line change). The CPU 11 displays the sum of the movement distance L of the set sewing order and the sum of the movement angle θ in the corresponding "distance" column and the "angle" column in the "sewing method" of the automatic sewing order setting screen AS. . Lθ1 (a, c, b) = Lθ1 (a, c) + Lθ1 (c, b).

  When the operator selects the first synthesis (leading stitch line change), the CPU 11 sets an optimum sewing order in consideration of both the movement distance L and the movement angle θ in a state where the first sewing line can be changed. . The value calculated from the movement distance L and the movement angle θ may be optimized more than the first total (fixed) depending on the sewing order. Therefore, the time taken for the sewing process of the sewing device 20 can be further shortened, and the load applied to the feed mechanism (particularly the feed motor) can be further reduced when the moving direction of the feed mechanism changes, so the operating efficiency and durability of the sewing device 20 Both improve further.

<Second comprehensive (fixed)>
In the second overall (fixed), the sewing order of the first sewing line a specified by the sewing data is fixed. The CPU 11 calculates movement distances L (a, b), L (a, c), movement angles θ (a, b), θ (a, c), respectively. The CPU 11 sets a sewing line having a smaller value Lθ2 obtained by the following calculation formula (Equation 4) in the next sewing order. T (θ ₀ ) and t (L ₀ ) in the equation respectively indicate the time (s) required for moving the moving angle θ of the reference value m and the time (s) required for moving the moving distance L for the reference value m . Lθ 2 (a, c) and the like can also be calculated by the same calculation formula.

  For example, when the value of Lθ 2 (a, b) is smaller than L θ 1 (a, c), the CPU 11 sets the sewing order (a, b, c) as the second total (fixed) sewing order . The CPU 11 displays the sum of the movement distance L of the set sewing order and the sum of the movement angle θ in the corresponding "distance" column and the "angle" column in the "sewing method" of the automatic sewing order setting screen AS. . When the operator selects the second total (fixed), the CPU 11 sets the optimum sewing order in consideration of both the movement distance L and the movement angle θ without changing the first sewing line. Therefore, since the time taken for the sewing process can be shortened and the load on the feed motor can be reduced, both the operating efficiency and the durability of the sewing device 20 are improved.

<2nd general (start stitch line change)>
In the second total (leading sewing line change), the sewing order of the first sewing line a designated by the sewing data can be changed. The CPU 11 sets each sewing line a, b, c as the first sewing line, calculates the movement angle θ and the movement distance L, respectively, and sews the next sewing line for which the value Lθ2 is smaller according to the formula 4 As the order, each sets the sewing order. For example, when the set sewing order is (a, c, b), (b, c, a), (c, b, a), the CPU 11 sets Lθ 2 (a, c, b) and Lθ 2 (b, c). , A) and Lθ 2 (c, b, a), the sewing order having the smallest value is set to the second synthetic (leading stitch line change) sewing order. The CPU 11 displays the sum of the movement distance L of the set sewing order and the sum of the movement angle θ in the corresponding "distance" column and the "angle" column in the "sewing method" of the automatic sewing order setting screen AS. . Lθ2 (a, c, b) = Lθ2 (a, c) + Lθ2 (c, b).

  When the operator selects the second total (start sewing line change), the CPU 11 sets an optimum sewing order in consideration of both the movement distance L and the movement angle θ in a state where the first sewing line can be changed. . There are cases where the value calculated from the movement distance L and the movement angle θ can be optimized more than the second total (fixed) by the sewing order. Therefore, the time taken for the sewing process of the sewing device 20 can be further shortened, and the load applied to the feed mechanism (particularly the feed motor) can be further reduced when the moving direction of the feed mechanism changes, so the operating efficiency and durability of the sewing device 20 Both improve further.

<Change of start point SS and end point SE>
When the operator checks the start point / end point change frame BX of the sewing order display screen, the start point SS and the end point SE of each sewing line can be changed. When the operator checks the start point / end point change frame BX, the CPU 11 sets the sewing order in consideration of replacement of the start point SS and the end point SE. For example, at the time of distance priority (fixed), the CPU 11 sets L (a, b), L (a, c), L (-a, b), L (-a, c), L (a,-b) , L (a, -c), L (-a, -b) and L (-a, -c) are respectively calculated. "-" Indicates that the start point SS and the end point SE are interchanged. For example, when L (-a, -c) is the smallest value, the CPU 11 sets a sewing line starting from SEa to SSa as an end point as the first sewing order, and starting from SEc to SEc as a start point to sewing lines The next sewing order is used. The CPU 11 calculates L (−c, b) and L (−c, −b) respectively, and for example, when L (−c, b) is smaller than L (−c, −b), SSb Set the sewing line starting from and ending with SEb as the third sewing line.

  When the operator checks the start point / end point change frame BX, the CPU 11 sets (−a, −c, b) as a distance priority (fixed) sewing order in this specific example. The CPU 11 displays the total of the moving distances L in the corresponding "distance" column in the "sewing method" of the automatic stitching order setting screen AS. When the operator checks the start point / end point change frame BX and selects distance priority (fixed), the CPU 11 does not change the first sewing line, and the start point SS and the end point SE can be exchanged. The sewing order of the movement distance L is set. Therefore, the movement distance L is shorter than in the state where the start point / end point change frame BX is not checked, and the time required for the sewing process can be further shortened, so that the operation efficiency is further improved.

  When the operator checks the start point / end point change frame BX and selects distance priority (start stitch line change), the CPU 11 can change the first sewing line, and can switch the start point SS and the end point SE. In the state, the sewing order of the shortest movement distance L is set. The movement distance L is shorter than in the state where the start point / end point change frame BX is not checked. Therefore, since the time taken for the sewing process of the sewing device 20 can be further shortened, the operation efficiency of the sewing device 20 is further improved.

  When the operator checks the start point / end point change frame BX and selects angle priority (fixed), the CPU 11 does not change the first sewing line, and it is the shortest in a state where the start point SS and the end point SE can be exchanged. The sewing order of the movement angle θ is set. Therefore, it becomes smaller than the state where the start point / end point change frame BX is not checked. Therefore, since the load applied to the feed mechanism (in particular, the feed motor) can be further reduced when the moving direction of the feed mechanism changes, the durability of the sewing device 20 is further improved.

  When the operator puts a check in the start point / end point change frame BX and selects the angle priority (start stitch line change), the CPU 11 can change the first sewing line, and can switch the start point SS and the end point SE. In the state, the sewing order of the shortest movement angle θ is set. The movement angle θ is smaller than in the state where the start point / end point change frame BX is not checked. Therefore, since the load applied to the feed mechanism (in particular, the feed motor) can be further reduced when the moving direction of the feed mechanism changes, the durability of the sewing device 20 is further improved.

  The operator checks the start point / end point change frame BX and selects the first total (fixed) or the second total (fixed). The CPU 11 sets an optimal sewing order in consideration of both the movement distance L and the movement angle θ in a state in which the first sewing line is not changed and in which the start point SS and the end point SE can be switched. The value calculated from the movement distance L and the movement angle θ can be optimized more than the state where the start point / end point change frame BX is not checked. Therefore, the time taken for the sewing process of the sewing device 20 can be further shortened, and the load applied to the feed mechanism (particularly the feed motor) can be further reduced when the moving direction of the feed mechanism changes, so the operating efficiency and durability of the sewing device 20 Both improve further.

  The operator puts a check in the start point / end point change frame BX, and selects the first total (start stitch line change) or the second total (start stitch line change). The CPU 11 sets an optimum sewing order in consideration of both the movement distance L and the movement angle θ in a state in which the first sewing line can be changed and in which the start point SS and the end point SE can be switched. The value calculated from the movement distance L and the movement angle θ can be optimized more than the state where the start point / end point change frame BX is not checked. Therefore, the time taken for the sewing process of the sewing device 20 can be further shortened, and the load applied to the feed mechanism (particularly the feed motor) can be further reduced when the moving direction of the feed mechanism changes, so the operating efficiency and durability of the sewing device 20 Both improve further.

  FIG. 6 shows an example of a screen during reproduction when the operator selects a sewing method and selects the second sewing order reproduction button RSB2. FIG. 6 shows an example in which the next sewing line of the sewing line of the start point SS1 and the end point SE1 is changed to the sewing line of the start point SS6 and the end point SE6. The first sewing order reproduction button RSB1 and the second sewing order reproduction button RSB2 both change to the stop buttons RSB1 and RSB2. As shown in FIG. 6, the sewing lines of the start point SS6 and the end point SE6 are the sewing lines of the current sewing order, and in this example, are surrounded by a rectangular frame. The sewing order display area AR2 highlights the number indicating the current sewing order (in this case, the second sewing line "No. 2") in the list of sewing lines. By encircling the sewing lines in a rectangle and highlighting them in the list of sewing lines in the sewing order display area AR2, it is possible to highlight the sewing lines of the current sewing order so that the operator does not misjudge them. Since the operator does not have to repeat the reproduction many times, the operator can shorten the confirmation time of the sewing order. Therefore, the work efficiency of the operator is improved. The method of enclosing the sewing line of the current sewing order in a rectangle is only an example of a method of emphasizing the sewing line of the current sewing order, changing the color of the sewing line or thickening the sewing line The sewing line may be surrounded by a frame other than a rectangular shape, or the boxed area may be further marked. In this manner, when the operator selects the sewing method on the automatic sewing order setting screen AS and selects the second sewing order reproduction button RSB2, the display unit 14 sews the sewing line unit in accordance with the sewing order set in the selected sewing method. Is sequentially displayed in the display area AR1, and the sewing lines in the current sewing order are displayed emphatically.

  The above is the method of sewing order reproduction when the operator selects the second sewing order reproduction button RSB2. Besides selecting the second sewing order reproduction button RSB2, the operator can move the second progress bar PB2 to execute sewing order reproduction. For example, when the operator selects the same sewing method and moves the second progress bar PB2 to the second position corresponding to the sewing order, the display unit 14 displays the screen shown in FIG. The display unit 14 simultaneously displays the first and second sewing lines and highlights the second sewing line. Thereafter, the display unit 14 displays the sewing lines in the third and subsequent sewing orders in accordance with the above-described method. When the second progress bar PB2 has been moved to the position corresponding to the first, third, fourth,...

<Automatic sewing order setting process>
The flow of the automatic sewing order setting process according to the present embodiment will be described with reference to FIGS. 7 and 8. The CPU 11 reads the program stored in the storage unit 12 and executes the automatic sewing order process. The automatic sewing order setting process is triggered by selection of the automatic sewing order button ASB on the sewing order display screen shown in FIG. 6 as a trigger. At this time, the display area AR1 displays all the sewing lines in accordance with the sewing order specified by the sewing data.

  The CPU 11 determines whether the operator has selected the automatic sewing order button ASB (S11). When it is determined that the operator does not select the automatic sewing order button ASB (S11: NO), the CPU 11 repeats S11. When it is determined that the operator has selected the automatic sewing order button ASB (S11: YES), the CPU 11 sets candidates for the optimum sewing order of each sewing method (S12). At this time, the CPU 11 determines whether or not there is a check in the start point / end point change frame BX. If there is a check, candidates for the optimum sewing order of each sewing method can be changed in a state where the start point and end point of each sewing line can be changed. Set each one. When there is no check, the CPU 11 sets candidates for the optimum sewing order of each sewing method without changing the start point SS and the end point SE of each sewing line specified by the sewing data.

  The CPU 11 displays the automatic sewing order setting screen AS (S13). The automatic sewing order setting screen AS reflects and displays the contents set in S12 in the “sewing method” column, the “distance” column, and the “angle” column. The CPU 11 determines whether the operator has selected the sewing method on the automatic sewing order setting screen AS (S14). When it is determined that the operator has not selected the sewing method (S14: NO), the CPU 11 determines whether the operator has selected the cancel button B2 on the automatic sewing order setting screen AS (S15). When it is determined that the operator selects the cancel button B2 (S15: YES), the CPU 11 ends the automatic sewing order setting process.

  When it is determined that the operator has not selected the cancel button B2 (S15: NO), the CPU 11 returns to S14. When it is determined that the operator has selected the sewing method (S14: YES), the CPU 11 displays all the sewing lines in the display area AR1 of the main screen in accordance with the sewing order of the selected sewing method (S16). The CPU 11 determines whether the operator has selected the second sewing order reproduction button RSB2 of the automatic sewing order setting screen AS or moved the second progress bar PB2 (S18).

  When the CPU 11 determines that the operator has neither selected the second sewing order reproduction button RSB2 of the automatic sewing order setting screen AS nor moved the second progress bar PB2 (S18: NO), the CPU 11 proceeds to S110. When it is determined that the operator has selected the second sewing order reproduction button RSB2 of the automatic sewing order setting screen AS or moved the second progress bar PB2 (S18: YES), the CPU 11 executes the sewing order reproduction process (S19). ). The sewing order reproduction process will be described later.

  The CPU 11 determines whether the operator has selected the sewing method on the automatic sewing order setting screen AS (S110). The process of S110 is similar to the process of S14. When the CPU 11 determines that the operator has selected the sewing method (S110: YES), the process returns to S16. When it is determined that the sewing method has not been selected (S110: NO), the CPU 11 determines whether the operator has selected the continue button B1 on the automatic sewing order setting screen AS (S111). When determining that the operator has not selected the continue button B1 (S111: NO), the CPU 11 determines whether the operator has selected the cancel button B2 on the automatic stitching order setting screen AS (S112).

  When it is determined that the operator has not selected the cancel button B2 (S112: NO), the CPU 11 returns to S18. When it is determined that the operator has selected the cancel button B2 (S112: YES), the CPU 11 displays all the sewing lines in the display area AR1 of the main screen according to the original sewing order (sewing order instructed by the sewing data) (S113). The CPU 11 ends the automatic sewing order setting process.

  When it is determined that the operator selects the continue button B1 (S111: YES), the CPU 11 reflects the sewing order corresponding to the sewing method selected in S14 or S110 in the sewing data (S114). At this time, the CPU 11 individually displays the sewing lines in the sewing order display area AR2 in accordance with the sewing order, and displays all the sewing lines in the display area AR1 of the main screen in accordance with the sewing order. The CPU 11 ends the automatic sewing order setting process.

<Sew order reproduction processing>
The flow of the sewing order reproduction process of the present embodiment will be described with reference to FIG. The lock stitch order reproduction process is a process corresponding to S19 of the automatic sewing order setting process.

  The CPU 11 determines whether the operator has selected the second sewing order reproduction button RSB2 (S21). When it is determined that the operator does not select the second sewing order reproduction button RSB2 (S21: NO), the CPU 11 determines whether the operator has moved the second progress bar PB2 (S22). When it is determined that the operator has not moved the second progress bar PB2 (S22: NO), the CPU 11 returns to S21 and repeats the above-described processing.

  When it is determined that the operator has selected the second sewing order reproduction button RSB2 (S21: YES), the CPU 11 controls the display unit 14 to change the second sewing order reproduction button RSB2 to the stop button RSB2 ( S23). The CPU 11 hides the display area AR1 of the main screen except the sewing start point SS0 (S24).

  The CPU 11 sequentially displays sewing lines at a predetermined time interval in sewing line units in the display area AR1 in accordance with the sewing order (S25). The CPU 11 determines whether all the sewing lines have been displayed in the display area AR1 (S26). When it is determined that all the sewing lines have been displayed (S26: YES), the CPU 11 ends the sewing order reproduction process. When the CPU 11 determines that all the sewing lines are not displayed (S26: NO), the CPU 11 determines whether the operator has selected the stop button RSB2 (S27). When the CPU 11 determines that the operator has not selected the stop button RSB2 (S27: NO), it determines whether the operator has moved the second progress bar PB2 (S28).

  When determining that the operator has moved the second progress bar PB2 (S28: YES), the CPU 11 proceeds to S211 described later. When the CPU 11 determines that the operator has not moved the second progress bar PB2 (S28: NO), the process returns to S25. In S27, when the CPU 11 determines that the operator selects the stop button RSB2 (S7: YES), the sewing order reproduction is stopped and all the sewing lines are displayed in the display area AR1 (S29). The CPU 11 changes the stop button RSB2 to the second sewing order reproduction button RSB2 and returns the second progress bar PB2 to the initial position (S210). The CPU 11 ends the sewing order reproduction process.

  In S22 or S28, when the CPU 11 determines that the operator has moved the second progress bar PB2 (S22: YES), a sewing line 縫 い in the sewing order corresponding to the movement position of the second progress bar PB2 is simultaneously displayed Display in the area AR1 (S211). The CPU 11 sequentially displays the next and subsequent sewing orders of the sewing order corresponding to the movement position of the second progress bar PB2 at predetermined time intervals in sewing line units (S212). The CPU 11 proceeds to S26 and executes the above-described processing (S26 to S210).

<Main effects>
The terminal device 10 changes the sewing order of the sewing data to a candidate of the sewing order of the sewing method selected from the list of sewing methods of the automatic sewing order setting screen AS by the operator. Therefore, the operator can select a sewing order that meets the operator's needs from among various needs.

  The terminal device 10 sets a sewing order optimal for each sewing method as the sewing order corresponding to each sewing method. Therefore, when the operator selects a sewing method that meets the needs, the sewing device 20 can perform the sewing process in accordance with the optimum sewing order for the selected sewing method.

  When the operator selects the automatic sewing order button ASB, the terminal device 10 sets candidates for the optimum sewing order of each sewing method. Therefore, when the operator selects the sewing method, the terminal device 10 can immediately display all the plurality of sewing lines in accordance with the sewing order candidates of the selected sewing method.

  The terminal device 10 sequentially displays sewing lines in a sewing line unit in accordance with the sewing order. Therefore, the operator can indicate the sewing order earlier than the conventional slow display, and the operator's work efficiency is improved. The terminal device 10 highlights the sewing line corresponding to the current sewing order. For example, even in the situation where a large number of sewing lines are displayed on the display unit 14, the operator can easily understand the sewing order of the sewing lines, and miss the sewing lines corresponding to the current sewing order. The possibility can be reduced. Therefore, since the operator does not have to repeat the reproduction, the work efficiency of the operator is improved.

  When the operator moves the second progress bar PB2, the terminal device 10 simultaneously displays the sewing line tack in the sewing order corresponding to the moved position in the display area AR1, and the subsequent sewing lines are performed according to the sewing order Display sequentially in sewing line units. For example, even if the operator misinterprets the sewing order of the sewing lines, the terminal device 10 can start reproduction from any sewing order with the second progress bar PB2. Therefore, since the operator does not have to reproduce the sewing order from the beginning, the work efficiency of the operator is improved.

<Modification>
In the above embodiment, the terminal device 10 displays the sewing order display screen superimposed on the main screen. However, the present invention is not limited to this, and both may be displayed on one screen. Sewing methods are: distance priority (fixed), distance priority (start stitch line change), angle priority (fixed), angle priority (start stitch line change), first general (fixed), first general (start stitch line change) , The second total (fixed), the second total (start stitch line change) may not be included, or may be only a part.

  In the above embodiment, when the automatic sewing order button ASB is selected, the CPU 11 sets the candidate for the sewing order optimal for each sewing method. For example, when the operator selects a sewing method from the list of sewing methods in the automatic sewing order setting screen AS, the CPU 11 may set only the candidate for the sewing order of the selected sewing method. good. FIG. 10 is a part of a flowchart of an automatic sewing order setting process when setting only sewing order candidates of the selected sewing method. The difference is that the process of S31 is added instead of the process of S12, and the others are the same as the automatic sewing order setting process of the embodiment described above. Since the CPU 11 sets only the sewing order candidate of the sewing method selected by the operator, the processing load on the CPU 11 can be reduced.

  A program or the like for executing the automatic sewing order setting process may be stored in a disk device or the like included in a server device on the Internet, and the terminal device 10 may download various programs.
