Description

Knit design device, design method, and design program {KNIT DESIGN DEVICE, DESIGN METHOD, AND DESIGN PROGRAM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to knit design, and more particularly, to conversion from pattern data (paper data) to knitting data and the like.

Patent document 1 discloses generating external shape data (data of a tissue) of a knitted fabric based on pattern data of the knitted fabric, and inputting design data such as intarsia or jacquard therein. Doing. The pattern data is vector data, the unit of which is length, which is data for each part of the knitted fabric. By the way, in order to convert the pattern data into the number of stitches, data such as the degree of deformation of the knitted fabric by the stretching ratio, the self weight, and the like in finishing processing is required in addition to the size of the stitches. Do. In this regard, Patent Document 2 discloses measuring the longitudinal and horizontal sizes of the stitches after finishing, and converting the pattern data into the number of stitches based thereon. However, even when using the method of patent document 2, considerable skill is required in order to convert pattern data into the number of stitches. For example, a knitted fabric is deformed by its own weight. For example, a neck hole tends to be widened laterally by the weight of a sleeve, and a thin knitted fabric such as a sleeve is easily stretched. have.

When the pattern data is converted into the number of stitches, it is necessary to form molding lines for realizing increase and decrease as the next step. Here, it is necessary to arrange the fashion mark in accordance with the increase and decrease so as to look regularly and beautifully, and also to adjust the silhouette of the part. In addition, the molding line needs to be easily determined for knitting in consideration of the burden on the yarn and the like so that the knitting line can be efficiently knitted in a flat knitting machine. Therefore, considerable skill is required in creating a forming line. For this reason, division of labor is generally performed by a designer creating pattern data and a knit technician converting the number of stitches.

Japanese Patent Laid-Open No. 7-70891 Japanese Patent 2676182

The basic problem of this invention is to make it possible to easily generate data in units of stitches from pattern data.

A further problem in the present invention is to support the selection of a suitable molding line.

Another further object of this invention is to make it possible to feed back the data of the created stitch unit to a later design.

The knit design apparatus of this invention is a knit design apparatus which converts the pattern data of a knit fabric into the data of a stitch unit,

First pattern data generating means for receiving an input of the completed size of each part of the knitted fabric, and generating first pattern data of each part representing the size inputted as vector data;

Second pattern data generating means for converting the first pattern data of each part into second pattern data indicating a size proportional to the number of stitches as vector data;

By converting the second pattern data of each part into the number of stitches and generating a forming line at the side end of the part, raster data representing each part in stitch units is generated. And raster data generating means for performing the same.

In the knit design method of the present invention, in the method of converting the pattern data of the knitted fabric into the data of the stitch unit using a knit design device,

A step for accepting an input of the completed size of each part of the knitted fabric by the knit design device and generating first pattern data of each part representing the size input as vector data;

Converting, by the knit design device, first pattern data of each part into second pattern data representing a size proportional to the number of stitches as vector data;

And a step for generating raster data representing each part in stitch units by converting the second pattern data of each part into the number of stitches by the knit design device and generating a forming line at the side end of the part. It features.

In the knit design program of the present invention, in the program for converting the pattern data of the knitted fabric into data in stitch units using a knit design device,

On the knit design device,

A step for accepting an input of the completed size of each part of the knitted fabric and generating first pattern data of each part indicating the size inputted as vector data,

Converting the first pattern data of each part into second pattern data representing a size proportional to the number of stitches as vector data;

By converting the second pattern data of each part to the number of stitches and generating a forming line at the side end of the part, a step for generating raster data representing each part in stitch units is executed.

In the present invention, first pattern data is first generated as vector data. This data expresses the finished size (indicative dimension) of the part, and it is not necessary to consider the size of the stitch in the longitudinal and lateral directions, and the stretching in finishing after knitting. As described above, the first pattern data need not consider problems specific to knits, such as stretching and deformation of the knitted fabric, by data representing what shape parts are required. Next, the first pattern data is converted into second pattern data representing a size proportional to the number of stitches as vector data. In this way, the problem of not being the size according to the indicated dimension is solved in the process of converting the first pattern data into the second pattern data. Then, the second pattern data is converted into the number of stitches of the part, and a molding line is generated at the side end of the part, thereby converting the part into raster data (data in stitch units) representing the stitches. And in a knit design device, or other design system, raster data is converted into knit data. As a result, when a designer designs the first pattern data, it is possible to simply convert it into raster data and to generate a molding line which is regular and easy to knit.

Preferably, the raster data is converted into knitted data by the converting means.

Preferably, in the state where the raster data and the second pattern data are superimposed on the monitor, editing means for accepting the editing of the raster data and changing the forming line is further provided. In this case, when there are a plurality of forming lines corresponding to the second pattern data, an appropriate forming line can be easily selected.

Also preferably, inverse conversion means for inversely converting the raster data into the second pattern data is further provided. In this way, the second pattern data for the design which is well evaluated in the market can be obtained, which can be used as a reference for later design and can be used as data of which molding line is to be generated from the second pattern data.

[Example]

1-10, the knit design apparatus 2 of an Example, a knit design method, and a knit design program are shown. In Fig. 1, 4 is a bus, 6 is a CPU, and 8 and 10 are memories. The memory 8 stores a program such as a knit design program, and the memory 10 stores data such as design data and knitting data. 12 and 16 are interfaces. 12 denotes an interface with external memory, which performs input / output with an external memory 14 such as a CD-ROM, a USB memory, etc., and the network interface 16 performs a connection with the Internet. The knit design program is stored in the external memory 14 and stored in the memory 8.

18 is a color monitor, 20 is a mouse, 22 is a keyboard, and 24 is a color printer. The knit design device 2 uses the bus 4 to the color printer 24 as a computer to realize the pattern data creation unit 26 to inverse conversion unit 38 for fabric. The pattern data preparation part 26 for textiles produces the pattern data of each part of a knitted fabric, for example, a part of a front body, a back body, a sleeve, etc. as vector data. For example, a pattern data (first pattern data) for fabric is created by the designer inputting the part's instruction dimension, part attribute, type, and the like from the keyboard 22 or the like. The attributes of the part include the type of the part such as the front torso, the back torso, the sleeve, and the like, and the parts in the part such as the arm hole, the neck hole, the hem rubber, and the like. Pattern data for woven fabric represents each part by, for example, actual dimensions.

In parallel with the creation of the pattern data for the fabric, for example, data such as the material of the yarn such as the type and thickness of the yarn to be used, the gauge of the flat knitting machine, the type of the finish, and the like are input. Moreover, you may input these data at the time of converting the pattern data for textiles into the pattern data (second pattern data) for knits.

The pattern data creation unit 28 for knit converts the pattern data for fabric into the pattern data for knit (second pattern data) which is vector data which shows the number of stitches. The macro memory unit 30 is used for this conversion, and the macro memory unit 30 stores, for example, an expansion ratio (shrinkage ratio) and strain for each part due to finishing after knitting. The shrinkage ratio may be stored for each combination of material and finish, or may simply be stored for each kind of finish. As the deformation for each part, the neck hole may be easily extended laterally by being attracted to the sleeve, and the elongated knitted fabric such as the sleeve may be easily expanded as the deformation for each kind of part. The macro storage unit 30 stores the correction ratios for these. Moreover, which part of a part is a neck hole, etc. are described as an attribute of a part.

Preferably, for one standard pointing dimension, a large number of data are generated by the size of the knitted fabric and by the body shape. When the size of the knitted fabric is changed, it is not enough to merely deform the standard pattern data, and the macro storage unit 30 stores data on how to change the length and width of the part. In addition, the macro storage unit 30 also stores data of which parts of which parts are to be changed at any ratio according to the body shape. And the pattern data creation part 28 for knit knits the pattern data for textiles by the macro which the macro memory | storage part 30 memorize | stores using the attribute and size (indication dimension) in the pattern data for textiles. Convert to dragon pattern data. In addition, a database may be used instead of the macro storage unit 30.

The raster data generation unit 32 converts the pattern data for knit into the number of stitches in the longitudinal direction and the width direction, and generates forming lines at the side ends of the parts. Let's do it. For the conversion of the number of stitches, for example, the keyboard 22 or the like is input at any stage in the length and width of the stitches, or the number of stitches per unit length and per unit width. When the vertical and horizontal sizes of the stitches are applied to the pattern data for knits, the number of stitches of the part, that is, the number of stitches in each course in which the stitches are laterally arranged and the number of courses in the longitudinal direction are determined. And once the number of stitches is determined, it is determined in which course how many stitches to increase or decrease. The molding line may increase or decrease inside the part by a line of increase and decrease and may decrease or increase at the end of the part. If an increase or a reduction is made inside the part, a fashion mark appears in that place. Whether to increase or decrease on the inside of the part or to increase or decrease on the end is input at any stage with the keyboard 22 or the like. The raster data generation unit 32 generates a forming line corresponding to the shape (generally straight line) of the side end portion in the pattern data for knit. The forming line is connected by short line segments and the appearance is curved. And a fashion mark appears regularly, the knitting in the flat knitting machine is easy, and the silhouette of a part is beautiful, and the raster data generation part 32 produces | generates the molding line according to the rule based on experience. Data representing the shape of the part in stitch units is raster data.

In general, there are a plurality of candidates for the molding line, and even when there is only one candidate, it cannot be said that an optimal candidate is generated from the beginning. The combining unit 34 superimposes the raster data and the pattern data for knit on the color monitor 18. The editing unit 35 allows the designer to edit the molding line by the mouse 20, the keyboard 22, or the like from this state.

36 is a knitting data creating unit that converts raster data into knitting data. The knitting data indicates the type of stitches in addition to the data that can directly drive the flat knitting machine (negotiation knitting data), and data that can be converted into knitting data for editing and consultation in the knit design device 2 or the like (broad knitting data) ). The inverse transform unit 38 inversely converts the knitting data or the raster data which is the basis thereof into pattern data for knits. For example, a combination of knit pattern data and raster data is added to the macro storage unit 30 or the like in accordance with a designer's input.

2 and 3 show the conversion from pattern data for fabric to raster data. In step 1 of Fig. 2, pattern data for fabric is input. This data indicates the size of the part as vector data, and the pattern data for the fabric is obtained by the designer inputting the indicated dimensions of each part, the attribute of the part, the type of the part, the size of the part, the material, the gauge of the knitting machine, and the like. It is generated by the creation unit 26. The pattern data for knits is obtained by converting this data by taking into account the shrinkage rate for each part or part and knitting tissue, and deformation after knitting in the neck hole, sleeve, and the like (step 2). The pattern data for knit is vector data and shows the size proportional to the number of stitches. In the case of developing a plurality of design data for each size and body shape, the pattern data for a plurality of knits is developed in consideration of the correction of the length and width. For these processes, the macro stored in the macro storage unit 30 is used, and the pattern data creation unit 28 for knit is executed.

Enter the number of stitches per knitting length, the number of stitches per knitting width, or the length and width of the stitches. In addition, the raster data generation unit 32 converts the pattern data for knit into the number of stitches in the longitudinal direction and the width direction, and approximates the outline of the pattern data for knit to the forming line. In this way, the raster data generation part 32 generates raster data (step 3). This data is the data in stitch units, and in step 4, the raster data and the pattern data for knit are superimposed so that the designer can correct the raster data.

If there are additional design data such as intersha and jacquard, these data are added (step 5). Then, raster data is converted into knitted data (step 6). According to the knitting data obtained as described above, the knitted fabric is knitted by knitting the parts individually or by joining the parts to each other, and finishing the knitted fabric.

It is convenient to be able to feed the well-received design into the future design work. In step 7 of Fig. 3, the knitting data of the favorable design is converted into raster data. If raster data is stored, step 7 may be omitted. In step 8, raster data is converted into pattern data for knit. Then, a color monitor or the like is superimposed with the pattern data for the original knit, for example (step 9). In this way, it is possible to know what is preferable as the pattern data for knits, and to refer to a later design. In the macro storage unit 30 or the raster data generation unit 32, the preferred example of the pattern data for knit is stored (step 10), which is used as a reference when converting the pattern data for knit, or as raster data. You can refer to it when converting.

4 to 9 show the process of design. Fig. 4 shows the pattern data 40 for the fabric, where 41 is the front torso, 42 is the torso, respectively, and the torso of the torso, respectively, 43 is the sleeve. This data is converted into the pattern data 50 for knits in Fig. 5, where 51 is the front body, 52 is the rear body, and 53 is the sleeve. In the pattern data 50 for knit of FIG. 5, the shape of a torso, the shape of an arm hole, the shape of a neck hole, etc. are changed.

6 shows a part of pattern data for knit. The pattern data 60 for knit is comprised by connecting a vector in order. In addition, the scale of the figure has shown the magnitude | size corresponding to a stitch.

Fig. 7 shows the generation of the forming lines 71 and 72 from the pattern data 70 for knit, in which two forming lines 71 and 72 are shown as candidates. The designer selects and edits the desired one from the displayed molding line.

The mark 80 on the left side of FIG. 8 is a mark omitting a grid indicating stitches, and a mark indicating stitches is added to the mark 82 on the right side. 84 is pattern data for knits, and is linear data, and the candidate of a shaping line to this is 86. Although the pattern data 84 is generally linear data, it is not possible to execute the increase or decrease in the flat knitting machine as it is. The pattern data can have any slope, but the slope that can be used as a forming line is limited. For this reason, the molding line 86 is slightly different from the pattern data 84. The forming line 86 is generated in accordance with the empirical rules stored by the raster data generator 32 so that the increase or decrease is made in a regular and easy-to-organize manner so that the knitting is efficient and a beautiful silhouette. The designer can edit the forming line 86 from the marks 80, 82 of FIG. 8.

Fig. 9 shows an example of the design, in which, on the left side, an example in which the knit technician manually generated the molding line was performed on the same pattern data for the knit. Is shown on the right. In the examples, a forming line with smoother and less bumpyness is obtained.

It is convenient if the knitting in the market is good for the reference of future design. For knitted fabrics that have been well evaluated in the market, knitting data is inversely converted into raster data, and raster data is inversely converted into pattern data for knits. 10, 100 is original pattern data for knits, and 102 is pattern data for knits inversely converted from raster data. In this way, it can be seen that it is preferable to design from the beginning like the pattern data 102 instead of the pattern data 100. In addition, it is understood that during the conversion from the pattern data for knit to the raster data, it is preferable to convert the raster data after converting it once as in the pattern data 102. These rules are stored in the macro storage unit 30 or the raster data generation unit 32 here.

According to the Example, the following effects can be acquired.

(1) The part can be designed as pattern data for fabric without considering the properties such as knit stretching and site-specific deformation. Once the design of the part is obtained, raster data can be generated via the pattern data for knit.

(2) In the conversion to the raster data, the molding line can be edited in a state of being superimposed with the pattern data for knit.

(3) Cases which are preferable as pattern data for knit can be accumulated about the design which the market evaluation was good.
