Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a mold piece arranging device for arranging a plurality of mold pieces on a material having a handle so that the required scale becomes small. For example clothing, which assembles pieces
This can be applied to industrial fields such as shoes.

(Prior Art) Conventionally, a program for minimizing the loss rate is stored in advance in a computer, and the loss rate is minimized based on the area of a certain area and the shape and size of the required number of mold pieces. A mold piece arrangement method in which the mold piece arrangement is determined by repeating calculation processing is known, for example, as described in US Pat. No. 3,596,063.

However, according to the method for arranging mold pieces, there is the disadvantage that it takes a long time to determine the arrangement of mold pieces with the minimum loss rate, and it takes an even longer time when the width of the certain area is determined.

In addition, when the width of a certain area is determined, even if the arrangement of mold pieces with the minimum loss rate is determined, the ratio (required scale ratio) between the required length for arranging the mold pieces and the input required length is It's not always the minimum.

Therefore, the applicant of the present invention previously submitted a mold piece arranging device (Japanese Patent Application No. 104784/1984) which eliminates such inconveniences.

The mold piece arrangement device includes an input means for inputting data regarding the mold piece assembly, a plurality of mold piece patterns, and a plurality of mold piece patterns obtained by grading the mold piece patterns according to predetermined rules. For each of various combinations of the mold piece pattern storage means, the number of mold pieces, and the shape and size classification of the mold piece assembly, the required scale is used to arrange the mold piece patterns within a certain area. A creation procedure storage means for storing a plurality of creation procedures to be created so as to minimize the number of mold pieces; and when data is output from the input means, a plurality of mold piece patterns corresponding to the output are extracted from the mold piece pattern storage means. A first extraction means and a creation procedure for a combination of the number of mold pieces corresponding to the output when data is output from the input means, and the shape and size classification of the mold piece assembly from the creation procedure storage means. A second extraction means extracts, and a plurality of mold piece patterns extracted by the first extraction means are arranged in a certain area based on the creation procedure extracted by the second extraction means, and the essential size of the result of the arrangement is When is smaller than the input essential length, output the array of mold piece patterns as a marker, and when all the essential lengths of the array of mold piece patterns extracted from multiple creation steps are larger than the input essential length, output the array of mold piece patterns as markers. The present invention is characterized by comprising a selection output means for outputting, as a marker, an arrangement of mold piece patterns that is closest to the specified required length.

(Problem to be Solved by the Invention) When creating a garment by sewing patterned pattern pieces such as the front piece, side pocket lids, back, collar, etc. When this happens, the two handles must match each other, but with the above-mentioned proposed device, it is not possible to determine the arrangement of the mold pieces so as to reduce the required scale while considering such points.

The present invention relates to an improvement of the proposed device described above, and is capable of arranging a plurality of mold pieces with patterns on a material to be cut so that the patterns match each other and the required scale ratio is small. It is an object of the present invention to provide a mold piece arranging device that can arrange a plurality of mold pieces on a material to be cut without causing any trouble even when the material is cut with deviations in size.

(Means for solving the problems) In order to achieve the above-mentioned object, the present invention has the following features:
As shown in the figure, there is an input means for inputting data regarding the mold piece assembly and pattern data of the material to be cut, and a plurality of mold piece patterns and a plurality of mold piece patterns graded according to predetermined rules. A mold piece pattern storage means for storing each mold piece pattern, and a creation procedure for arranging the mold piece patterns in a certain area so that the required scale ratio is minimized, the number of mold pieces and the mold piece assembly. When data regarding a mold piece assembly is inputted from the input means, a plurality of mold piece patterns corresponding to the data are stored as a mold piece pattern. a mold piece pattern extracting means for extracting the mold piece pattern from the storage means and correcting the mold piece pattern with a clearance amount corresponding to a deviation in pattern dimensions due to expansion and contraction of the material to be cut to obtain an apparent mold piece pattern; and a mold piece assembly. Correct the size of the mold piece assembly among the data related to the clearance amount, and create a creation procedure for the number of mold pieces and the combination of shape and size classification of the mold piece assembly corresponding to the corrected data. A creation procedure extracting means extracts from the storage means and a pattern is created in a certain area using the pattern data of the material to be cut inputted from the input means, and the pattern of the certain area and the predetermined pattern of each mold piece are added to the certain area. Arrange multiple apparent mold piece patterns based on the pattern matching with the matching points and the extracted creation procedure, and if the essential length of the arrangement result is smaller than the input essential length, then the mold piece pattern at that time is Outputs the array as a marker, and if the results of arranging multiple apparent mold piece patterns based on the extracted multiple creation procedures are all larger than the input essential length, then the result will be one that is even close to the input essential length. an array output means for outputting the array of the mold piece pattern as a marker, representing the pattern matching point of the mold piece in the mold piece pattern output from the array output means in absolute coordinates,
It is characterized in that the pattern matching point is used as the starting point of a machine such as a cutter.

(Function) When creating a garment by sewing multiple molded pieces with patterns, such as the front piece, side pocket lids, back, collar, etc., for example, to make the patterns of the front piece and side pocket lids, such as stripes, match each other. For example, as shown in the second figure, stripe matching points G are set at specific positions on the front piece F, and these stripe matching points G are aligned with the striped lines H of the fabric.

In addition, when the material to be cut, such as cloth, expands and contracts when handled, for example, the stripes H should be at regular intervals as shown in the second figure, but the intervals between the striped lines H are irregular as shown in the third figure. In this case, a certain area as shown in the second diagram corresponding to the fabric, that is,
Marker area J displayed on the display device
When the arrangement of a plurality of mold pieces is determined so that the striped line H displayed in the marker area matches the stripe matching point G of the mold piece and the required scale ratio is minimized, this determined plurality Layer the array of mold pieces on the fabric K shown in the third figure, and check the stripe matching point G of the pattern pieces shifted as shown in the same figure.
When trying to match the striped line H of the fabric K with the striped line H of the fabric K, it is not possible to do so because there is not enough room in the fabric K.

Therefore, the amount of clearance is determined in advance based on past statistical data, and a certain area J is set as shown in Figure 4.
A plurality of mold pieces are arranged so that the required scale ratio is minimized with a margin of this clearance amount L.

Based on the above considerations, we can explain the effect of this proposal.
When data related to the mold piece assembly, such as the dimensions of the person being measured, such as the bust, waist, and hips, and the material to be cut, such as the pattern dimensions of the fabric, are entered using the input means,
The mold piece pattern extraction means extracts from the mold piece pattern storage means a plurality of mold piece patterns, such as the front part, side pocket lid, back, collar, etc., corresponding to the data regarding the mold piece assembly, and the dimensions of the mold piece pattern are extracted from the mold piece pattern storage means. The above-mentioned clearance amount is added to obtain an apparent mold piece pattern that takes the above-mentioned clearance amount into consideration, and the creation procedure extraction means extracts the size of the mold piece assembly from the data regarding the mold piece assembly by the above-mentioned clearance amount. The production procedure for the combination of the number of mold pieces and the shape and size classification of the mold piece assembly corresponding to the modified data is extracted from the production procedure storage means. Then, by the array output means, stripes of the stripe data of the material to be cut inputted from the input means are created in a certain area, and in the certain area,
Based on the extracted creation procedure, stripes in the area are matched with predetermined stripe matching points on each mold piece, and a plurality of apparent mold piece patterns are arranged. If the essential length of the arrangement result is smaller than the predetermined essential length, the arrangement of the mold piece patterns at that time is output as a marker. If all of the extracted key lengths from the plurality of production procedures are larger than the input key length, the arrangement of mold pieces that is closest to the input key length among them is output as a marker.

Here, since the stripe matching point on the mold piece is expressed as an absolute coordinate, the starting point of a machine such as a cutter can be positioned at the stripe matching point based on this output.

(Example) Examples of the present invention will be described below with reference to the accompanying drawings.

FIG. 5 shows a block diagram of one embodiment of the invention.

In the figure, 1 is a mold piece coordinate reading device, 2 is a mark reader, 3 is a CPU, 4 is a memory, 5 is a display device, and 6 is an automatic drafting device or an automatic cutting device.

The mold piece coordinate reading device 1 places predetermined mold pieces to be arranged in a marker area, which is a fixed area, on a coordinate reading table and digitizes the shape of the mold pieces as coordinate values.This output is sent to the interface and CPU
3 and stored in the memory 4. When an offline system is adopted, it is composed of the coordinate reading table, a card puncher, and a card reading device. A commercially available coordinate reading device 1 is used.

The memory 4 consists of a magnetic disk, magnetic tape, or other suitable data storage device, and the display device 5 consists of a cathode ray tube (CRT), both of which are commercially available.

Both the mold piece pattern storage means and the mold piece array creation procedure storage means described in the claims correspond to the memory 4 in the configuration shown in FIG.

The memory 4 stores, for example, the body shape of the person to be measured (body A,
B-type, AB-type, etc.), each master pattern (mold piece pattern) is graded according to certain rules (the master pattern is modified to suit the purpose of various sizes). grading pattern (mold piece pattern)
are converted into coordinates and stored, so that when an input means, for example, a mark reader 2 inputs measurement data of a person to be measured, a master pattern or a grading pattern corresponding to the measurement data is read out.

Since the method of grading a master pattern according to certain rules is not particularly different from the conventional method, its explanation will be omitted (see, for example, Japanese Patent Publication No. 4147/1983).

In addition, the memory 4 stores the arrangement of mold pieces to be arranged within a certain area for each of various combinations of the number of mold pieces and the shape and size classification of the mold piece assembly so that the required scale is minimized. Memorize multiple steps to create.

For example, the names of men's clothing, such as top and bottom, with a zipper, or with a spare (corresponding to the number of mold pieces such as sleeves and collars), the body shape of the person being measured (body A, body B, etc., and the shape of the mold piece assembly) For each of the various combinations of bust size categories of the person to be measured (e.g. bust 80-90 cm, corresponding to the size category of the mold piece assembly), apply the mold piece to a certain area of fabric. A plurality of creation procedures (creation programs) for creating an array so that its required scale is minimized are stored.

One of the creation programs has the following contents, for example.

(1) Place the mold piece A near the lower left corner of the marker area 7, which is a fixed area displayed on the display device 5, as shown in the sixth diagram.

(2) Place mold piece B on top of mold piece A and close to the left side of marker area 7, and move it in the Y direction (vertical direction in the figure) until it contacts mold piece A.

(3) Move the mold piece C to the left side of the marker area 7 and place it below the vertical width W of the marker area.

(4) Place the mold piece D on the right side of the mold piece C and below the vertical width of the marker area 7, and move it in the X direction until it contacts the mold piece C.

(5) Place the mold piece E below the mold piece D and to the left of its right side, and move it in the Y direction until it contacts the mold piece D.

When placing the mold pieces A to D in the marker area 7 as described in (1) to (5) above, in order to minimize the required scale of the arrangement of the mold pieces, adjust the vertical or horizontal inversion. Let's do it.

At the time of (3) above, when mold pieces B and C overlap in the Y direction, this production program is stopped and another extracted production program is executed.

FIGS. 7A, 7B, and 7C show examples of arrangement of mold piece patterns in a certain area by a plurality of creation programs for one extracted combination.

This creation program uses a computer to transfer the mold piece pattern created in the grading process onto the display device 5, and the operator uses a tablet or the like to randomly display the pattern in the marker area 7.
Create a marker by moving etc. with , and write the position of each mold piece obtained from this marker, the positional balance with adjacent mold pieces, the upward direction of movement, etc., and more detailed manual work etc. in a mold piece arrangement programming language. Convert and create.

FIG. 8 shows a flowchart from inputting measurement data to obtaining markers for arranging mold pieces in a certain area using the above creation program.

Measurement data, i.e. dimensions (bust, waist,
Hips, etc.) silhouette (inter, conti), product name (with spare, top and bottom, etc.), design (Benz, etc.)
When inputting the fabric (width, required length, pattern size, i.e. lattice width or stripe width) into the computer using the mark reader 2, the input will be, for example, silhouette: inter, product name: top and bottom, body shape: A-body, etc. If the design is a vent-shaped design, the fabric is sorted to see if it has a pattern (stripes or lattice) after going through steps ~, and the apparent bust size is determined by adding the above-mentioned clearance amount to the bust size measured at the step. Assuming that the bust size is between 80cm and 90cm, a program is created to create an array of mold pieces that corresponds to the combination of the silhouette, product name, body design, and bust size of 80cm to 90cm. select.

On the other hand, although not shown, the mold piece M to be subjected to stripe matching is widened by the clearance amount L in the direction perpendicular to the stripe line as shown by the dashed line in FIG.
Create M′. Of course, such corrections are not made for mold pieces that do not require stripe matching. In the case of a checkered pattern, as shown by the two-dot chain line in FIG. 9, the clearance amount L' is also expanded in the vertical direction of the figure.

In addition, a striped state is created in the above-mentioned certain area according to the input striped dimensions of the fabric.

The apparent mold pieces created as described above and the mold pieces that are not to be matched with stripes are arranged in the certain area according to the above-mentioned mold piece array creation program, and the apparent mold pieces are matched with the stripes. Match the points to the stripes in a certain area (step).

Next, the required length for the arrangement of both mold piece patterns is compared with the required length input into the computer (step), and if the required length is shorter than the input required length, the arrangement of this mold piece pattern is marked with a marker (1). (next marker), and draw it using an automatic drafting machine or automatic cutting machine at the actual size (or an appropriate enlarged or scaled size), or directly cut the clothing material at the actual size. Create data (step) Here, the shape of each mold piece is expressed in relative coordinates, and the stripe matching points are expressed in absolute coordinates. The stripe matching point shall be the starting point of the automatic drafting machine or automatic cutting machine.

When the resulting length of the mold piece pattern array created by executing the creation program is larger than the input length (when the required scale ratio is greater than 1), the mold piece pattern is created again using the remaining selected programs. Repeat the array (step).

When it is found that the resulting length of the mold piece pattern array obtained by executing the remaining creation program is smaller than the input required length, the mold piece pattern array at that time is output as a marker.

When the remaining programs are executed the number of times (set number of times) and all the lengths are larger than the input length, the one closest to the input length is used as a marker (primary marker) and displayed along with the length on the display device 5.
(Figure 10).

Then, using a doublet or the like, the operator moves one or more mold piece patterns in the primary marker area to another display area of the display device 5 and places them, so that the arrangement of the mold piece patterns is correct. The secondary marker is made to fit within the input required length of the secondary marker area, and a secondary marker is obtained (step). Using this marker, data to be supplied to an automatic drawing machine or an automatic cutting machine is created in the same manner as described above (step).

(Effects of the Invention) As explained above, according to the present invention, mold piece patterns are formed within a certain area for each of various combinations of the number of mold pieces and the shape and size classification of the mold piece assembly. A plurality of creation procedures are prepared to create an array such that the required scale ratio is minimized, and when data regarding the mold piece assembly and pattern data of the material to be cut are input, it corresponds to the data regarding the mold piece assembly. A plurality of mold piece patterns are extracted, and the mold piece patterns are corrected with a clearance amount corresponding to the deviation in pattern dimensions due to expansion and contraction of the material to be cut to obtain an apparent mold piece pattern. The size of the mold piece assembly in the data is corrected by the clearance amount, and the creation procedure for the number of mold pieces and the combination of the shape and size classification of the mold piece assembly corresponding to the corrected data is extracted. , in a certain area where the pattern of the material to be cut has been created, pattern matching is performed between the pattern of the certain area and the predetermined pattern matching points of each mold piece, and a plurality of apparent shapes are created based on the extracted creation procedure. Arrange mold piece patterns, and if the essential length of the array result is smaller than the input essential length, output the array of mold piece patterns at that time as a marker, and create an apparent mold piece based on the extracted multiple creation steps. When the results of arranging each pattern are all larger than the input key length, the array of mold piece patterns that is closest to the input key length is output as a marker, so patterned mold pieces can be mutually patterned. They can be arranged on the material to be cut so that they match and the required scale ratio is small, and also have the effect that there is no problem in arranging a plurality of mold pieces of the material to be cut, which may have misaligned pattern dimensions due to expansion and contraction. .
