【Example】
Embodiments of the present invention will be described below with reference to the drawings.
In FIG. 1, the pattern data storage means 1 includes stitch data for forming a plurality of patterns, display data for displaying the patterns on the display means 6, and a necessary lower thread amount Hk required for sewing the patterns. Is remembered. This pattern can be selected by the pattern selection means 2, and is configured so that one or a plurality of patterns can be selected.
A pattern code is attached to each pattern, and the pattern can be recognized by the code. When the pattern itself is formed from a plurality of small patterns, a pattern code is attached to each small pattern as shown in the drawing, and stitch data, display data, and necessary lower thread amount Hk are stored in each pattern.
The display data of the pattern selected by the pattern selection means 2 is sent to the display control means 5 and displayed on the display means 6. Further, the stitch data of the pattern is sent to the stitch formation mechanism control means 3, and the embroidery stitch of the pattern is executed by the stitch formation mechanism 4.
The display control means 5 is connected to a color designation means 10 so that the user can designate the color of the selected pattern. It is also possible to determine the color of the pattern in advance and store it in the pattern data storage means 1 together with the pattern data.
Information on color designation by the color designation means 10 is also sent to the sewable pattern detection means 9.
[0006]
The necessary lower thread amount Hk in the pattern data storage means 1 is sent to the sewable pattern detection means 9.
In this embodiment, the necessary lower thread amount Hk is stored in the pattern data storage means 1, but the present invention is not limited to this and may be provided separately as the necessary lower thread amount data giving means.
It is also possible to store the number of stitches of the pattern without directly storing the necessary lower thread amount, and to calculate and output the necessary lower thread amount from here. That is, it is also possible to determine the necessary amount of bobbin thread required for one stitch in advance and multiply this by the number of stitches for calculation. Further, it is also possible to obtain a sewing distance by accumulating the relative movement amount of the stitch data and multiplying this by a predetermined constant to obtain the required amount of lower thread.
[0007]
The remaining amount of the currently installed lower thread in the stitch formation mechanism 4 is detected by the lower thread remaining amount detecting means 8. In this embodiment, the lower thread remaining amount detecting means 8 detects the remaining amount of the lower thread attached to the bobbin of the stitch forming mechanism 4 and is disclosed in the above-mentioned Japanese Patent Laid-Open No. 1-126996. Are using things.
[0008]
The sewable pattern detection means 9 compares the necessary lower thread amount Hk in the pattern data storage means 1 with the lower thread remaining amount from the lower thread remaining amount detection means 8 and is detected by the lower thread remaining amount detection means 8. It is determined whether the pattern selected by the remaining amount of the lower thread can be sewn, and the sewn pattern is detected.
If the colors of the selected patterns are different at this time, it is determined whether or not sewing is possible according to the order of the colors specified by the determination color order assigning means 7.
[0009]
The judgment color order assigning means 7 may be, for example, an operation means that can be operated by the user to specify an arbitrary color order, or a predetermined color order according to the color of the selected pattern. May be provided by the judgment color order providing means 7. For example, it is possible to detect the necessary lower thread amount for each color, and to give the order of the color with the smaller necessary lower thread amount or the color order with the larger necessary lower thread amount.
The determination color order assigning means 7 can also specify a determination order between patterns of the same color, and can specify a user's arbitrary order or a predetermined order. For example, a priority order can be determined according to the required lower thread amount Hk, such as a pattern having a larger required lower thread amount Hk within the same color pattern, and this priority order can be sewn according to the selected pattern. You may make it instruct | indicate to the pattern detection means 9. FIG. It is also possible to instruct the pattern arrangement order and the sewing order as the judgment order. Further, any other order such as the order stored in the pattern data storage means 1 can be designated.
[0010]
The display control means 5 attaches a sewable display to the sewable pattern detected by the sewable pattern detection means 9 and displays it on the display means 6. For example, a sewn pattern can be displayed in a specific color different from the color of the pattern, or can be displayed by a change in brightness, blinking, diagonal lines, or the like.
[0011]
With reference to FIG. 5, a specific example will be described with respect to the designation of the judgment color order by the judgment color order assigning means 7 and the detection and display of the sewable pattern by the sewable pattern detection means 9.
For example, it is assumed that five patterns with red, white and yellow are selected as shown in FIG. The required lower thread amount Hk of each pattern is set in the order of size.
As shown in (B), when the judgment color order giving means 7 gives an instruction to judge in order of decreasing required thread amount Hk within the same color in the order of yellow, red and white. , (1) → (5), the sewable pattern detecting means 9 determines whether or not sewing is possible. That is, first, it is determined whether or not sewing is possible from the amount of remaining lower thread for the small yellow, and if possible, the large yellow is determined next. At this time, the amount obtained by subtracting the amount of lower thread used for the small yellow from the amount of remaining lower thread is compared with the required amount Yk of the large yellow thread. Next, compare in the order of small red, large red, and white. In the case of (B), yellow small, large and red small sewing is possible, but red large sewing can only be performed halfway, and the sewable pattern detecting means 9 is yellow small, large sewing. Only the small red and red are judged to be sewn, and these patterns are displayed with diagonal lines.
When sewing is possible halfway like a large red, the halfway possible sewing range may be displayed with diagonal lines or the like as shown, or may not be displayed at all.
[0012]
In the example of (C), the case where the judgment color order giving means 7 instructs to judge from the order of white, red, yellow, and the large required lower thread amount Hk is shown. Red large and small can be sewn, and these three patterns are indicated by diagonal lines. The large white can be sewed partway and displayed halfway or not displayed at all.
Note that the above shows an example of determination and display, and other determinations and display are naturally possible within the scope of the present invention.
In addition, the display of the pattern that can be sewn can adopt various forms such as a figure such as a diagonal line, a pattern, or a dot, or a display shade or color-coded paint, a change in brightness, or blinking.

The pattern selection button 22 and the color designation button 27 are operated, the pattern is selected and the color is designated, the pattern is displayed (steps S1 and S2), the sewing pattern display selection button 29 is operated (step S3), and sewing is performed. When the judgment order is instructed from the in-color judgment order selection button 35 and the possible pattern judgment color order selection button 33 (step S4), the central processing unit 20 follows the program of the sewable pattern judgment ordering program storage device 34. The selected patterns are ordered, and pattern numbers k = 1 to N are assigned according to the order. Then, the order is stored in the temporary storage device 31 (step S5). Next, the detection value of the remaining amount of lower thread by the lower thread remaining amount detection sensor 28 is input (step S6), the selected number of patterns N is stored (step S7), and the accumulated necessary lower thread amount Hs is set to zero. (Step S8). Further, k is set to 1 (step S9).
Then, for the first pattern, k = 1, the necessary lower thread amount Hk stored in the pattern data storage means 21 is compared with the remaining lower thread amount (step S10). If the remaining amount of the lower thread is larger than the required lower thread amount, the pattern is displayed in the temporary storage device 31 while being sewn-displayable, such as hatched lines, and the pattern code is stored in the temporary storage device 31 (step S11). Then, the necessary lower thread amount Hk of the pattern is accumulated in the accumulated necessary lower thread amount Hs (step S12), and it is determined whether k = N (step S13). If the remaining amount of the lower thread is smaller than the necessary lower thread amount Hk in Step 10, or if k is less than N in Step 12, 1 is added to k (Step S15), and the necessary lower thread amount Hk is sewn up to now. The accumulated value Hs of the necessary lower thread amount of the pattern that is made possible is added (step S16), and the process returns to step 9.
