Description

  The present invention relates to an embroidery data generation apparatus and an embroidery sewing machine.

  In recent years, embroidery devices that perform embroidery mechanically and those that have a function of causing a sewing machine to perform embroidery stitching have become widespread.

The problem to be solved is that when embroidery is mechanically performed by such an apparatus, the embroidery range is limited to the mechanical movable range of the embroidery apparatus. That is, it is impossible to embroidery in a range that is greater than the movable range of the mechanism that moves the cloth that is the embroidery object. Therefore, when embroidering a large number of patterns or large patterns that exceed the embroidery range, It is necessary to change the position of the cloth and repeat the embroidery several times.
Such a limit is particularly problematic in an embroidery machine. In other words, the movable range is limited to a very narrow range due to the rising portion of the sewing machine, so that the embroidery frame that supports the cloth becomes small and the number of embroidery to be combined is limited.
In order to solve this drawback, it is possible to sew a large number of patterns by changing the cloth to the embroidery frame, but it is usually necessary to change the embroidery frame by the number of patterns, and the work is difficult. is there. In addition, when replacing the embroidery frame, a completed embroidery pattern template is necessary to accurately match the embroidery seam, and a special device or the like must be used for alignment.
The present invention aims to remedy the drawbacks of the prior art described above.

To achieve the above objective,
The present invention relates to an apparatus for generating embroidery data for an embroidery sewing apparatus comprising a mechanism for holding an object to be embroidered and a sewing mechanism for executing embroidery sewing by moving relative to the holding mechanism. And means for storing a plurality of pattern data comprising stitch data for sewing the embroidery pattern and display data for displaying the embroidery pattern, Means for selecting arbitrary pattern data; means for displaying a pattern of the selected pattern data; means for setting positions between the plurality of displayed patterns; and a plurality of patterns When the position between the patterns is displayed and the positions between the patterns are set, the means for determining whether or not the plurality of patterns are within the embroidery range by the holding mechanism and the positions between the plurality of patterns are set. Depending on the setting of the means, Means for notifying the user when it is determined that the means for cutting is not within the embroidery range, and for correcting the stitch data of the pattern based on one reference position. The problem was solved by using an embroidery data generation device characterized by this.
In addition, the present invention has solved the problem by providing an embroidery data generation device in which means for displaying an embroidery possible range based on the movable range of a mechanism to be held is displayed together with a pattern.
The present invention also provides an embroidery data generating apparatus, wherein the holding mechanism has a frame for holding the cloth, embroidery sewing is executed in the frame, and the display means displays the frame shape as an embroidery range. This solved the problem.
In addition, the present invention solves the problem by using an embroidery sewing machine equipped with the above-described embroidery data generation device.

  According to the data generating apparatus and the sewing machine capable of embroidering according to the present invention, when a large number of patterns are selected, the position can be adjusted so that the pattern can be accommodated in a single embroidery range. The number of times can be reduced. In particular, the user can arbitrarily set the position of the pattern M. The determination device 7 is set with a plurality of patterns, and when the patterns M1 and M2 are brought closer to each other, the determination device 7 determines that the patterns fall within the same frame W1, and notifies the user accordingly. Embroidery can be performed within a range where embroidery can be performed once without changing the frame 40.

  When embroidering a large number of patterns or large patterns that exceed the embroidery range when performing embroidery sewing, even if a large number of patterns are selected, the position is set by means for setting the positions between the patterns. By adjusting the position, it is determined that it is within the embroidery range and is notified to the user so that the embroidery can be within the embroidery range at one time.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an embodiment in which a data generating apparatus of the present invention is incorporated in a sewing machine main body A capable of embroidery sewing.
The CPU 1 controls the entire sewing machine main body A in accordance with the program stored in the program storage device 2, operates the motor 31 via the sewing machine motor drive circuit 30, and causes the stitch forming mechanism 32 to execute sewing. The stitch forming mechanism 32 is provided with a needle 41 shown in FIG. The sewing speed is controlled by the rotational speed command device 38. 33 is a sensor, and 34 is a timing signal generator.
Further, the XY motor drive circuit 35 controls the XY motor 36, and the XY movement mechanism 37 is operated to perform embroidery sewing. Embroidery sewing and normal sewing can be selected by a sewing mode selection button 12. The XY movement mechanism 37 includes the embroidery frame 40 shown in FIG. 2, and the embroidery frame 40 holds the cloth as an embroidery object and moves it in the XY direction to perform embroidery sewing. ing. The movement of the embroidery frame 40 is limited by the movable range of the XY movement mechanism 37 and physical restrictions around the embroidery frame 40. That is, in the sewing machine main body A, there are no obstacles in the front-rear direction, but there is a rising portion B in the horizontal direction, and the horizontal movement of the embroidery frame 40 is restricted by this rising portion B. Therefore, only a relatively small embroidery frame 40 can be used.

The pattern data storage device 3 stores a plurality of pattern data, and includes stitch data for sewing each pattern and display data for the pattern, the embroidery frame, and the reference mark, and these are displayed. . The user selects a pattern with the pattern selection button 13, and the selected pattern is displayed on the display device 11 via the display control device 10.
FIG. 3 shows an example of display. Here, a pattern M1 and a pattern M2 are selected, and a frame W having the same shape and size and a cross C as a reference mark are displayed together with each pattern M.

The position of each pattern M can be set and corrected by the pattern position button 14, and the user can place the pattern M at a preferred position while looking at the display device 11.
The synthesis of these patterns M and the correction of the position setting are performed by the display data synthesis / correction device 6.

The cross C has a cross shape as shown in FIG. 3, and the crossing point is set as a reference point G, and an arrow D is provided at one end of the cross.
The frame W is rectangular and the upper left corner is the frame origin W0.
The position (Kx, Ky) of the reference point G from the frame origin W0 is the same in all the frames W1,2. Further, the direction of the arrow D is the same in all the frames W, and in this example, is parallel to the vertical short side of the frame W.

As described above, the user can arbitrarily set the position of the pattern M by operating the pattern position button 14. When the positions of a plurality of patterns are set, the determination device 7 is configured to determine whether or not the patterns are within the embroidery range. Since the embroidery possible range is the frame W in this embodiment, it is determined whether or not the embroidery range fits in the frame W. In the example of FIG. 3, since the patterns M1 and M2 do not fit in the same frame W, the determination device 7 determines to that effect. As shown in FIG. 4, when the patterns M1 and M2 are brought closer, the determination device 7 determines that the patterns M1 and M2 fit within the same frame W1, and changes the display of the frame W2, the cross C2, and the arrow D2 of the pattern M2 to that effect. The user is notified. The display of the frame W2, the cross C2, and the arrow D2 can take various forms such as changing the shape and color. In FIG. 4, the display of the frame W2 is displayed by a two-dot chain line. The display may be turned off. In FIG. 4, the display of the cross C2 and the arrow D2 is turned off. Moreover, it is also possible to perform text display and voice notification to the effect that it is stored.
The display data synthesizer / corrector 6 changes the display of the frame W2.

Simultaneously with the change of the display described above, the stitch data of the pattern is corrected by the stitch data correcting device 8. In this embodiment, the pattern M1 is left as it is, and only the stitch data of the pattern M2 is corrected. That is, since the positional relationship between the pattern M1 and the frame W1 does not change in this example, there is no need to correct the stitch data. On the other hand, since the coordinates of the stitch data of the pattern M2 were originally specified by the positional relationship in the frame W2, it is necessary to correct the coordinate to the positional relationship with the frame W1. In this embodiment, the stitch data is specified based on the reference point G, and the stitch data of the pattern M2 is corrected to the stitch data based on the reference point G1.
As described above, the pattern M1 and the pattern M2 are accommodated in the same frame W1, and embroidery can be performed once without changing the embroidery frame 40.

As shown in FIG. 3, when the distance does not fit in the same frame W, the distance calculation unit 4 between the reference points calculates the distance between the reference points G, and the distance display data generation apparatus 5 between the reference points displays the calculation result. The distance display data is generated based on the information and displayed on the display device 11.
In the example of FIG. 3, the distance between X and Y between the reference points G is displayed. For example, the distance between the reference point G1 and the reference point G2 is displayed as X1 = 50 and Y1 = 40.
By changing the cloth to the frame W according to the distance between the reference points G, the user can embroidery the pattern M1 and the pattern M2 on the cloth as displayed in two steps.

  It is also possible to provide the cross C at a position overlapping the frame W. For example, the frame origin W0 and the reference point G may be matched.

  The print command button 18 is operated when the user needs an actual size printed matter of the display content. By this operation, the print data generating device 19 generates the actual size print data of the content displayed on the display device 11. The printing apparatus 20 is configured to print. Since the printed matter output from the printing apparatus 20 is an actual size, it can be used as it is as a template.

The operation will be described with reference to FIG.
When the pattern is selected (step S1), the display data of the pattern is extracted from the pattern data storage device 3 and temporarily stored in the temporary storage device 9 (step S2). This is repeated until all patterns are selected (step S3). When there are a plurality of patterns (step S4), when the pattern position is set or corrected (step S5), the display data is corrected accordingly (step S6).
Then, the determination device 7 determines whether or not a plurality of patterns are within the embroidery possible range (step S7), and if so, displays that the frame W is accommodated (step S8).
If not, the distance between the reference points G is calculated by the distance calculation device 4 between the reference points (step S9), further distance display data is generated (step S10), and these display data are combined with display data / It is synthesized by the correction device 6 (step S11) and displayed on the display device 11 (step S12).
When a print command is issued by the print command button 18 (step S13), print data is generated by the print data generation device 19 (step S14), and the display contents are printed in actual size by the print device 20. (Step S15).

  When embroidering with an embroidery device that performs embroidery mechanically or with a function that allows the sewing machine to perform embroidery sewing, when embroidering many patterns or large patterns that exceed the embroidery range, Even if it is selected, it can be applied to an application in which the position can be adjusted within a range that can be embroidered once by adjusting the position.
