Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery data creating device for creating embroidery data necessary for an embroidery forming operation in a sewing device for forming embroidery of a predetermined pattern such as a picture or a character on a work cloth. .

[0002]

For example, in an embroidery sewing machine that automatically executes embroidery of patterns such as characters and symbols on a work cloth, a needle drop point for forming a stitch (for each stitch). The operation is performed based on embroidery data (stitch data) that specifies the X and Y movement amounts of the work cloth). The creation of embroidery data in such an embroidery sewing machine is executed by an embroidery data creation device which is configured independently of the sewing machine main body or built in the sewing machine main body.

In this embroidery data creation device, basic data for determining the shape of a pattern is stored in advance in a built-in ROM or provided externally by a storage medium such as a memory card, corresponding to a large number (many types) of patterns. It is designed to be used.

In this case, as the basic data, the block data constituted by dividing the contour of the pattern into a plurality of blocks such as a quadrangle continuous in the advancing direction of embroidery and the coordinates of each vertex thereof is used. ing. Then, for example, when the user selects a pattern on the touch panel or the like, the microcomputer reads the block data of the pattern,
The main side portion of each block is equally divided to perform needle development for obtaining a needle drop point (stitch data), thereby creating embroidery data.

The created embroidery data is stored in the embroidery data storage area of the RAM, for example. It should be noted that, for example, embroidery composed by combining a plurality of characters (such as "HAPPY")
If you want to apply to the work cloth, select a plurality of characters sequentially, and after selecting all the characters, specify the enlargement ratio, reduction ratio, or thread density of these combined characters, and then add new embroidery. The data will be created.

Thus, the embroidery formed on the work cloth by one embroidery data has a predetermined size according to the data, and has a predetermined thread density (a thread occupying a certain length in the embroidery advancing direction). Of the number of). On the other hand, particularly when the pattern is, for example, a character, it may be desired to form embroidery having various sizes and thread densities even if the pattern (character) is the same.

For this reason, the embroidery data creating apparatus is provided with editing functions such as enlargement, reduction, and thread density change, and the user specifies the enlargement or reduction rate and thread density for the reference embroidery. As a result, it is possible to create embroidery data corresponding to the data.

By the way, since the data capacity of embroidery data is substantially determined by the number of needle drop points, the data capacity increases as the size increases even if the patterns have the same shape.
Further, the larger the yarn density, the larger the data capacity. Furthermore, for example, regarding the letter pattern of the alphabet,
Since "B", "M", "W", etc. have more needle drop points than "I", "J", etc., the data capacity of embroidery data becomes large.

However, when the embroidery data is created as described above, especially when the pattern is formed by combining a plurality of characters, the following problems occur.

That is, since the embroidery data is created after the operation of selecting the pattern (character), the data capacity of the embroidery data is stored in the RAM depending on the number of selected characters or the shape of the character. The memory capacity was sometimes exceeded. In this case, the creation of the embroidery data becomes impossible on the way, and the user must reselect the character again, which is very inconvenient.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to prevent the creation of embroidery data for a pattern selected by a user from becoming impossible on the way. An embroidery data creation device is provided.

[0012]

In order to achieve the above object, the embroidery data creation apparatus according to claim 1 of the present invention is a basic data storage means for storing basic data for determining the shape of a pattern for a large number of patterns. A selection means for selecting a pattern stored in the basic data storage means, a setting means for setting an embroidery condition with an increase in embroidery data capacity relating to the selected pattern, and a selection by the selection means. Each time it is executed, the maximum data capacity detecting means for determining the maximum data capacity of the embroidery data when the setting means for the selected pattern has the largest data capacity, and the embroidery data are created based on the basic data and the embroidery condition. Embroidery data creating means, embroidery data storing means for storing embroidery data created by the embroidery data creating means, and the maximum data Are provided with a notification means for notifying that related to the pattern selection or embroidery condition set based on the storage capacity of the capacitor and the embroidery data storage means.

In this case, there is provided a comparing means for comparing the integrated value of the maximum data capacity obtained by the maximum data capacity detecting means with the storable capacity of the embroidery data storing means, and the notifying means is the integrating means. When the value exceeds the storable capacity, a notification to that effect can be provided (claim 2), and further, even after the notification by the notification means, the pattern selection operation can be continued. May be configured (claim 3).

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention (corresponding to claims 1 and 2) will be described below with reference to the drawings. In this embodiment, the present invention is applied to a domestic embroidery sewing machine, and this embroidery sewing machine has both a sewing device and an embroidery data creating device according to the present invention.

FIG. 3 schematically shows the outer appearance of the embroidery sewing machine according to this embodiment. The sewing machine main body 1 is constructed by integrally including an arm portion 3 above a sewing machine bed 2. A needle bar 5 having a needle 4 at the tip of the arm portion 3.
And a ring-shaped presser foot 6 through which the needle 4 passes. On the other hand, a needle plate 7 is provided on the upper surface of the sewing machine bed 2 corresponding to the needle bar 5, and a shuttle mechanism (not shown) is provided on the lower surface of the needle plate 7. Although not shown, the needle bar 5, the shuttle mechanism, the presser foot 6 and the like are synchronously driven by a sewing machine motor via a drive mechanism, and thereby perform a sewing operation.

The sewing machine bed 2 is provided with an embroidery frame 8 for holding the work cloth during the embroidery sewing operation, and the embroidery frame 8 and thus the work cloth can be freely moved in the horizontal direction on the sewing machine bed 2. A horizontal movement mechanism 9 is provided for the purpose. In this case, the embroidery frame 8 has a substantially rectangular frame shape, and is composed of an outer frame and an inner frame. By sandwiching the work cloth between them, the work cloth is held in a stretched state inside the frame. It has become.

Although not described in detail, the horizontal movement mechanism 9 causes the embroidery frame 8 to move by a Y-axis motor (not shown).
The movable body 10 configured to move freely in the axial (front-back) direction is configured to move freely in the X-axis (left-right) direction by an X-axis motor (not shown). As a result, the work cloth held by the embroidery frame 8 is moved by the horizontal movement mechanism 9 to an arbitrary position based on the unique XY coordinate system. The embroidery sewing operation is executed by driving the needle bar 5 and the like by the drive mechanism while moving the work cloth by the horizontal movement mechanism 9.

A start / stop key 11 is provided on the front surface of the arm portion 3 on the tip side, and a power switch 12 is provided on the lower portion of the right side wall surface of the sewing machine body 1. In addition to the embroidery, the embroidery sewing machine of the present embodiment can of course perform various types of general practical sewing (straight stitch, zigzag stitch, bleed stitch, etc.). In this case, the cloth presser 6 can be exchanged between the illustrated embroidery sewing and the practical sewing.
Further, the horizontal movement mechanism 9 portion is detachably attached to the sewing machine bed 2, and when the embroidery sewing is not performed, this portion is removed together with the embroidery frame 8 and replaced with a flat table for general sewing. Is able to.

An LCD 13 is provided on the front surface of the arm 3 as a display means for displaying various patterns and messages on the screen. A pattern selection screen (see FIGS. 6 to 8) and an edit screen are displayed on the LCD 13 when the user executes embroidery as described later. Further, a touch panel 14 (illustrated only in FIG. 4) that constitutes a selection operation unit is provided on the surface of the LCD 13. This touch panel 1
As is well known, 4 is configured by arranging transparent electrodes vertically and horizontally, and it is possible to detect a position touched by a user of the touch panel 14 with his / her fingers and to function as a selection unit and a setting unit.

As shown in FIG. 4, a controller 15 for controlling each mechanism is provided in the sewing machine main body 1. The control device 15 is mainly composed of a microcomputer, and includes a CPU 16, a ROM 17, and an RA.
The M18, the controller 19 and the input / output interface 20 are connected to each other via a bus 21. The sewing machine motor (driving mechanism), the X-axis motor, the Y-axis motor, etc. of the horizontal movement mechanism 9 are controlled by the controller 15 via the controller 19. The LCD 13 and the touch panel 14 are connected to the input / output interface 20.

In this embodiment, the external ROM card 22 is detachably connected to the controller 15. The external ROM card 22 stores pattern data (embroidery data, display data, and accompanying data such as color separation) corresponding to a relatively complicated pattern for a large number of patterns. To connect the external ROM card 22 to the control device 15, as shown in FIG. 3, the user detachably inserts the external ROM card 22 into the card insertion hole 23 provided in the right side wall portion of the sewing machine main body 1. It is supposed to be done by.

The ROM 17 includes a control program L for controlling the embroidery sewing operation and the practical sewing operation of the sewing machine.
A control program for display control of the CD 13, a data processing program for performing various data processing such as creation of embroidery data described later, and the like are stored. At the same time, the ROM 17 stores pattern data corresponding to a large number of patterns relating to embroidery sewing. In this case, the pattern data stored in the ROM 17 is, for example, a pattern of characters or symbols such as kana, alphabets, numbers, or a decorative pattern having a relatively simple shape. still,
The ROM 17 also stores display data other than the embroidery pattern, such as display data for teaching.

The pattern data includes basic data necessary for creating embroidery data, display data (for example, bitmap data) necessary for displaying each pattern on the LCD 13, and accompanying data. Here, in order to execute the embroidery sewing operation, finally, X, Y of the work cloth for each stitch is
Embroidery data indicating the amount of movement in the direction (needle drop position) or the like is required, but the data stored in the ROM 17 is basic data (block data) that determines the shape of the pattern. As for this basic data, for example, the pattern A is shown in FIG.
In the case of the letter "Y" shown in 0, the contour of the pattern A has a pair of main side portions 1-3 and 2-4 extending in the advancing direction of embroidery and a pair of sub-side portions 1-2 and 3-4 adjacent thereto. Block data is divided into a plurality of blocks K such as quadrangle surrounded by and (see FIG. 11), and is set as block data composed of a set of coordinates of vertices 1, 2, 3, 4 of each block K obtained. . Therefore, in this embodiment, the ROM 17 functions as a basic data storage means.

Further, in the RAM 18, as shown in FIG. 5, a basic data area 18a for storing basic data relating to the selected pattern, an embroidery condition area 18b for storing specified embroidery conditions, the basic data and the embroidery conditions. An embroidery data area 18c for storing embroidery data obtained by the embroidery data creation program based on the above is provided together with a working area and the like. Therefore, in this embodiment, the RAM 18 (embroidery data area 18a) functions as embroidery data storage means.

Now, as will be described in detail later in the description of the operation, when the user wants to execute the embroidery sewing operation by the software configuration, the control device 15 first displays a pattern on the screen of the LCD 13. Selection screen (Figs. 6-8)
Reference) is displayed. The user can select a desired pattern to embroider by looking at the pattern selection screen and operating the touch panel 14. In this case, not only one pattern can be selected but also a plurality of patterns can be sequentially selected. At this time, the control device 15 reads the basic data relating to the pattern selected by the user from the ROM 17 (or the external ROM card 22) and writes it in the basic data area 18a of the RAM 18.

Further, when the pattern selection is completed, the controller 15 causes the LCD 13 to display an editing screen (not shown). The user looks at this edit screen,
By operating the touch panel 14, the embroidery conditions such as the layout of the pattern, the enlargement / reduction ratio with respect to the reference size, the thread density (how many stitches S cross the center line 1 of the block K per unit length), etc. , Can be set.

Regarding the enlargement / reduction ratio and the yarn density, the upper limit value and the lower limit value suitable for actual use are preset, and any setting can be made within the range. The embroidery condition is the embroidery condition area 18b of the RAM 18.
Is written to.

When the setting of the embroidery condition is completed, the controller 15 creates the embroidery data based on the basic data and the embroidery condition. This embroidery data is created by equally dividing the main sides 1-3 and 2-4 of each block K from the basic data of the pattern A and the specified embroidery conditions, and the needle drop points a to f (see FIG. ) Reference) is calculated. Therefore, in this embodiment, the control device 15 functions as an embroidery data creating unit.

The control device 15 is operated by the user at L level.
When a pattern selection operation is performed on the pattern selection screen (see FIG. 6) of the CD 13, the maximum capacity of embroidery data relating to the pattern is obtained. In this case, when embroidering a combination of a plurality of patterns is applied to the work cloth, first, the plurality of patterns are sequentially selected, but the control device 15 selects each pattern by that time. The maximum data capacity of the embroidery data for all the applied patterns is calculated. Here, the maximum data capacity of the embroidery data means the data capacity of the embroidery data obtained at the maximum enlargement ratio and the maximum thread density for the selected pattern.

Further, the controller 15 compares the maximum data capacity of the embroidery data with the storable capacity of the embroidery data area 18c of the RAM 18, and if the maximum data capacity exceeds the storable capacity of the embroidery data area 18c. , L
Instead of the pattern selection screen displayed on the CD 13, a message that the maximum data capacity has exceeded the storable capacity, in this case, a message "Data capacity has exceeded the limit" is displayed. (See Figure 9). Therefore, the control device 15 functions as the maximum data capacity detecting means and the comparing means in the present invention, and the LCD 13 functions as the notifying means.

Next, the operation of the above configuration will be described with reference to FIGS. 1, 2, 7 and 8. The flow chart of FIG. 1 shows a procedure of processing executed by the control device 15 from pattern selection to sewing. First, referring to FIG.

First, when the power switch 12 of the sewing machine main body 1 is turned on, various initial operations are executed and the LC
An unillustrated initial screen (menu selection screen) is displayed on D13 (step S1). Here, when the user wants to execute the embroidery sewing operation, he / she operates the touch panel 14 to select an item of embroidery pattern selection. Then LCD
The pattern selection screen is displayed on screen 13 (step S
2). FIG. 6 shows one pattern selection screen for selecting a character pattern, in this case, uppercase letters of the alphabet. Here, based on the display data stored in the ROM 17, “A” and “B” are displayed on one screen. , “C” ... 26 alphabets are displayed in a form surrounded by a rectangular frame.

The user looks at the pattern selection screen and selects the character pattern for which embroidery is to be formed (step S3). This selection is made on the screen of the LCD 13 (touch panel 1
This is performed by directly touching the portion of the character pattern desired to be selected in 4) with a finger. Now, the user says "H
When it is desired to apply the embroidery "APPY" to the work cloth, first, the character pattern "H" is selected. When this selection is made (Yes in step S3), as shown in FIG.
"H" is displayed in the upper area of the pattern selection screen displayed in D13 (step S4).

Subsequently, in step S5, the basic data (block data) of the selected pattern is read from the ROM 17 and stored in the basic data area 18a of the RAM 18, and the maximum data capacity of the embroidery data relating to the selected pattern is calculated. It This maximum data capacity calculation process is
As shown in FIG. 10, it is calculated based on the basic data of the pattern “H” and the embroidery condition (in this case, the thread density and the reduction / enlargement ratio), which will be described in detail later.

After the calculation processing of the maximum data capacity, the controller 15 compares the maximum data capacity with the storable capacity of the embroidery data area 18c of the RAM 18, and if the maximum data capacity is less than or equal to the storable capacity ( Yes in step S6), and the pattern selection operation is repeated again (No in step S7).

Here, the flow chart of FIG. 2 shows the details of the process of calculating the maximum data capacity of the embroidery data of the selected pattern in step S5 of FIG. 1, and this process will be described below. This capacity calculation work depends on the basic data of the selected pattern and the data capacity of the embroidery data formed from the embroidery conditions specified in the edit mode, depending on the shape of the pattern, the thread density and the reduction / enlargement ratio. This is performed assuming that the data capacity is the largest. Specifically, it is the data capacity of the embroidery data that is calculated by setting both the enlargement ratio and the thread density to the maximum, and calculating from the enlargement ratio and the thread density and the basic data.

First, in step S21, the basic data of the selected pattern is stored in the basic data area 18a of the RAM 18.
Is stored. Then, the reduction / enlargement ratio and the thread density are set to the maximum values selectable in the edit mode (steps S22 and S23). Then, the needle drop point is obtained by calculation from the basic data and the embroidery condition to create the embroidery data (step S24), and the data capacity of the embroidery data is calculated (step S25). in this case,
When there are multiple patterns to be selected, the above operation is repeated each time the pattern is selected.
The data capacity finally obtained is an integrated value of the maximum data capacities regarding a plurality of patterns.

Returning to the flowchart of FIG. 1, the operation of selecting the letters "A", "P", "P", and "Y" following "H" is repeated according to the above-described selection procedure, and the pattern selection screen is displayed. “HAPPY” is displayed in the upper area (FIG. 8). If the maximum data capacity does not exceed the storable capacity even after the selection up to “Y” is completed (Yes in step S6), the user designates the end of the selection operation. Then, the mode is changed to the edit mode (Yes in step S7).
s), the screen of the LCD 13 is switched to an editing screen (not shown).

Here, when the layout, rotation, enlargement / reduction ratio, etc. of the pattern are designated by the operation of the touch panel 14 by the user (Yes in step S8), the contents are stored in the embroidery condition area 18b of the RAM 18. (Step S9). Similarly, when the thread density of the pattern is designated (Yes in step S10), the content is stored in the embroidery condition area 18b of the RAM 18 (step S11).

Then, the controller 15 controls the RAM 1
8 embroidery conditions stored in the embroidery condition area 18b and R
Embroidery data is formed for all the selected characters based on the basic data stored in the AM 18 (step S12). This embroidery data is stored in the embroidery data area 18c of the RAM 18 (step S13).

At this time, in steps S5 and S6,
The maximum data capacity of embroidery data for the selected pattern is RA
Since it is known that the storage capacity of M18 (embroidery data area 18c) is not exceeded, the entire embroidery data is created and stored without interruption during the creation of the embroidery data.

After creating the embroidery data in this way, the user selects the sewing operation (step S14) and starts the sewing operation (step S15), and the controller 15 stores the embroidery data and the ROM 17 in the ROM 17. Based on the program, each mechanism of the sewing machine is controlled to execute the embroidery sewing operation.

On the other hand, the user may select, for example, "HAPPY BI
I want to embroider the character pattern of "RTHDAY", "B"
It is assumed that when the character "" is selected, the maximum data capacity exceeds the storable capacity as a result of the calculation processing of the maximum data capacity (No in step S6). Then, as shown in FIG. 9, the error message "Data capacity has exceeded the limit" is displayed on the pattern selection screen, and the characters "HAPP" that were displayed in the upper area of the pattern selection screen until then are displayed.
"B" of "YB" is erased (steps S16 and S17).

At this time, the user first asks "HAP
Considering that only the "PY" embroidery is executed, when the "confirm" key displayed on the LCD 13 is pressed together with the error message (Yes in step S18), the error message disappears and the pattern selection screen is displayed again. Then, it is possible to shift to the edit mode as described above by the selection operation by the user (Yes in step S7). At this time, if the user considers changing the embroidery "HAPPY BIRTHDAY" and does not specify the continuation (pressing the "confirm" key), all the characters selected so far are canceled. Then, the process ends (No in step S18).

Therefore, the capacity of the embroidery data is the RAM 18
When there is a possibility of exceeding the storable capacity, it is possible to prevent the embroidery data from being created as it is.

As described above, according to this embodiment, when the basic data is processed based on the embroidery condition and the embroidery data is created, first, all the patterns selected by the user during the pattern selection operation are performed. The maximum value of the embroidery data capacity for the pattern is calculated. This maximum data capacity is calculated assuming that the data capacity of the embroidery data created based on the embroidery data and the basic data becomes the largest when the embroidery condition is set in the edit mode.

Therefore, until the pattern selection operation is completed, L
If no message is displayed on the CD 13, it means that the maximum data capacity of the selected pattern does not exceed the storable capacity of the embroidery data area 18a of the RAM 18. It can also be set in embroidery conditions.

If the maximum data capacity exceeds the storable capacity during the pattern selection operation, the user is notified to that effect, and the user cancels the selected pattern at that time. Perform a different pattern selection, or
First, it is possible to determine whether to create embroidery data for a pattern that has already been selected from among the embroidery desired by the user.
Therefore, since it is possible to create embroidery data for all patterns selected by the user, it becomes clear that it is impossible to create embroidery data when all patterns have been selected, as in the conventional case. The problem that the pattern selection operation must be redone can be prevented in advance.

By the way, in the above description, the case where the data capacity of a combination of a plurality of patterns exceeds the storable capacity is explained. However, even when one pattern is selected, the data capacity of the pattern is selected. When exceeds the storable capacity, the above-mentioned notification is automatically executed. Basically, even if the maximum enlargement ratio and thread density of one pattern does not exceed the storable capacity, as the storable capacity of the embroidery sewing machine becomes more diverse, one pattern The data capacity of may exceed the storable capacity. In addition, since the device for creating embroidery data has started to spread widely, it is desired to share the created pattern data. Data that does not exceed the limit is not always created. On the other hand, if the data is created in accordance with the sewing machine having the smallest storable capacity, the degree of freedom in creating the pattern will be hindered.

As a result, even if one pattern has a large area or a large number of overlapping stitches, it may exceed the storable capacity when the number of needle drop points is large. . Although the length of one stitch is long and the number of needle drop points is small, if the length of one stitch exceeds a predetermined length, for example, the distance less than the predetermined length is 1 byte. Although the data is composed, even if the data representing the distance exceeding the predetermined length is composed of 2 bytes, even one pattern may exceed the storable capacity.
However, with the above-mentioned configuration, since the maximum data capacity is calculated from the time when one pattern is selected,
Before combining the patterns, the operator can know a defect such as the incompatibility.

In the above embodiment, the maximum data capacity is
When the storage capacity of the RAM 18 is exceeded, it is impossible to select the pattern at that time. However, since the user does not always want to set the embroidery condition that maximizes the data capacity of the embroidery data, the embroidery condition that does not increase the data capacity (for example, minimize the thread density) is used. In the case of designating, it may be configured to be able to subsequently shift to the edit mode.

Further, in the present embodiment, the calculation of the maximum data capacity is executed when only one pattern is selected, but it is executed when a certain number of patterns of 2 or more is selected. It may be done.

In addition, the present invention is not limited to the above embodiment, but various expansions and changes can be made. For example, although the present invention is applied to a domestic sewing machine in the above-described embodiments, it may be applied to an industrial sewing machine, and, for example, a personal computer (notebook computer) or the like is used to embroider independently of the sewing machine. It is also possible to apply to a processing device that processes data.

Further, in the above embodiment, the work cloth side is moved with respect to the needle 4 by the embroidery frame 8, but the embroidery pattern is formed while moving the needle (needle bar) side with respect to the work cloth. It can also be applied to things and those that form an embroidery pattern while moving both the needle and the work cloth, without using an embroidery frame,
It can also be applied to those that form embroidery by moving the work cloth back and forth and left and right by needle swing and feed dogs.

Further, the storage means is not limited to the ROM and the external ROM card, but may be ROM only or RAM may be used, and various storage media including readable and writable magnetic disks, optical disks and the like. Can be used as Also, as a display means, L
Not limited to a CD, a CRT display or the like may be used.
Then, a separate switch or keyboard may be used as the selection means, and the display content and the like can be appropriately changed.

[0056]

As is apparent from the above description, according to the embroidery data creation apparatus of claim 1 of the present invention, each time the pattern is selected by the selecting means, the maximum data capacity of the embroidery data relating to the pattern is set. It is determined by the maximum data capacity detection means, and the notification means notifies the user regarding pattern selection or embroidery condition setting based on the maximum data capacity and the storable capacity of the embroidery data storage means. It can be seen that while selecting a pattern, the embroidery data of the selected pattern can be created. Therefore, it becomes impossible to create the embroidery data at the stage of selecting the pattern and subsequently setting the embroidery condition without knowing whether the pattern desired by the user can create the embroidery data as in the conventional case. That problem can be eliminated.

At this time, the integrated value of the maximum data capacity of the embroidery data relating to a plurality of patterns and the storable capacity are compared by the comparing means, and if the integrated value exceeds the storable capacity, the fact is notified. By doing so, the user can surely know that the selection pattern must be changed (claim 2).

Moreover, if it is possible to continue the pattern selection operation even after the notification by the notification means, the user judges that
It is possible to change the pattern, partially correct a plurality of patterns, and the like, and the embroidery sewing operation can be executed only for the pattern selected before being notified by the notification means (claim 3). .
