Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking device using a computer.

[0002]

2. Description of the Related Art Conventionally, a so-called paper pattern has been mainly used for manufacturing articles such as clothes and the like from cloth, leather, etc., and serves as a design drawing. In order to form one solid from a flat material such as cloth or leather, a normal clothing item is composed of a plurality of parts. For example, the skirt of FIG. 12 has five parts, a front skirt, a back skirt, a front belt cloth, a front lining skirt and a back skirt, as shown in FIG. 11A, and accessories such as a belt core and a fastener. Are sewn together.

When making a garment using a fabric with a pattern, it is preferable to use the fabric so that the pattern will continue when stitched together with respect to the eye-marking position. For this reason,
When using a fabric with a pattern, a special marking operation called pattern matching may be performed.

This has conventionally been done while arranging the parts on the actual fabric. Taking the case of marking the above-mentioned skirt on the material of the lattice pattern as an example, the procedure of pattern matching marking will be described based on FIG. 11. First, the pattern of the front skirt is placed on the cloth. At this time, if there is a pattern instructing instruction such as "the center of the lattice should be on the skirt hem", place it according to it. Next, a line such as A is written in order to mark the position of the reference pattern on the front skirt paper pattern (see FIG. 11B). After that, the pattern of the front skirt and the pattern of the back skirt are butted against each other to find the position of the back skirt that is connected to the position of the front skirt that was previously marked, and write the line A of the mark on the pattern of the back skirt (Fig. 11 ( See c)). Next, the pattern of the front skirt is returned to the original position on the cloth, and the pattern of the back skirt is placed at a position where the marked position is the same as the pattern of the marking position of the front skirt (FIG. 11 (d)). reference). In this way, pattern alignment marking was performed by repeating the work of placing the parts by marking the positions where the patterns match while observing the positions of the patterns on the parts placed in front.

The same applies when pattern matching marking is performed using CAD. Put each part on the cloth, put a mark (pattern matching point) at the position where the standard pattern will come, and arrange it so that the pattern that is temporarily generated on the CAD and the pattern matching point will match. It was a thing. The work of selecting the pattern matching points and marking them will be decided while tentatively arranging them on the fabric as in the case of marking by hand.

[0006]

However, according to the above-mentioned prior art, it is necessary to select in advance a point which is a guideline for pattern matching, and the work of arranging parts based on this point is required. However, there is a problem that the work is troublesome and requires skill.

However, the present invention has been made in order to solve the above-mentioned problems, and it is possible to perform pattern matching marking without having to preselect a point which is a standard for pattern matching. Is intended to provide.

[0008]

In order to achieve this object, the marking device of the present invention comprises a connection information storage means for storing the relationship between parts when they are sewn together,
A connection position determination means for determining a connection position between a plurality of parts from the data of the connection information storage means, and a pattern matching mark at a position where the connection position determined by the connection position determination means and the pattern match Pattern matching marker generating means for displaying the marker on the display means, pattern matching position storing means for storing the position where the pattern matching marker is displayed, and pattern matching position stored in the pattern matching position storing means And pattern matching determination means for determining whether or not the pattern and the pattern match.

[0009]

In the marking device of the present invention having the above construction, the connecting position determining means determines the connecting position between the thrown part and the placed part from the information stored in the connecting information storage means. Then, the pattern matching marker generating means generates a pattern matching marker at the connecting position. When the arrangement is instructed, the pattern matching determination means determines whether the pattern matching marker position matches the pattern.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing the configuration of an embodiment in which the present invention is embodied on a workstation as an apparel CAD system.

In addition to the main body 1, the workstation is connected with a keyboard 6, a mouse 7, a digitizer 8, a hard disk 9 as a storage device, a display 10 as a display means, and a plotter 11 as an input device. Further, the workstation body 1 is mainly composed of a CPU.
2, ROM 3, RAM 4, and interface 5, and controls the entire apparel CAD system including marking processing.

The ROM 3 stores a system program 31 for controlling the apparel CAD system. In the RAM 4, the X pattern pitch information table 41,
Y pattern pitch information table 42, parts placement information table 43, pattern matching direction flag table 44, throwing part number table 45, connecting line segment table 46, pattern matching mark table 47, placement parts counter table 48.
A work area 49 and the like are provided. The pattern alignment mark table 47 constitutes pattern alignment position storage means for storing the position where the pattern alignment marker is displayed.

The interface 5 is for communicating with various peripheral devices, and connects the CPU 2 with various external devices such as the display 10. The keyboard 6 and the mouse 7 are for performing operations such as instructing the CPU 2 for marking work. The digitizer 8 is for inputting the pattern shape. The hard disk 9 stores pattern data such as the shape information table 91 and the connection information table 92. The display 10 displays the shape of the template based on the data, and the plotter 11 prints the shape of the template based on the data.

In the shape information table 91, the shape information of FIG. 3 (a) is entered for all points constituting each part. The coordinate information is determined based on the reference axis for each part. The point data are arranged continuously according to the order of forming the line.

The connection information table 92 constitutes a connection information storage means for storing the relationship between the parts to be sewn together, and all the points forming each part are connected as shown in FIG. 3 (b). Information is filled in.
The connecting cords here are indicated by attaching the same symbols to the points which are at the same position when assembled in a solid. The data of the constituent points are arranged in the same order as the shape information table 91.

In this apparel CAD system,
The area of the cloth for marking simulation is called a marker sheet. As shown in FIG. 10, when the patterns are repeated at a certain interval, the pattern is simulated on the marker sheet by designating the pattern intervals in the ground eye direction (X direction) and the direction orthogonal to the ground eyes (Y direction). You can display specific patterns. The pitches of the patterns are X pattern pitch information 41, respectively, as an array of pattern intervals in the X and Y directions.
(Called GX) and Y pattern pitch information 42 (called GY).

The parts already placed on the marker sheet are called placement parts. The information regarding the positions of the parts arranged on the marker sheet is stored in the parts arrangement information table 4 as an array of the parts arrangement information in FIG.
It is held at 3. A part that is moving and whose position on the marker sheet has not been determined is called a throwing part. If there is a thrown-in part, the thrown-in part number is held in the area 45 on the RAM. The placement of the throwing parts is performed as it is at the position designated by the user.

This embodiment is constructed as described above.

The operation based on the above configuration will be described below.

First, the flow of processing in marking will be described with reference to FIGS. 3 to 9 while following the operation procedure.

Consider a case where another part is about to be placed on the place where one part is placed on the marker sheet. As an example, FIG. 5 shows the state of the screen when the rear skirt is thrown into the place where the front skirt is arranged. The operation during the parts throwing will be described along with this.

While the throwing parts are being moved, a pattern matching position display is performed to show the relationship of the pattern matching positions between the placement parts and the throwing parts. A state in which this display is performed is shown in FIG. For the pattern matching position, a pattern matching mark is generated at one of the intersections of the line segment connecting the arranged parts and the throwing parts and the pattern, and the straight line connecting the two is displayed as a guide. Here, when the user gives a pattern matching position changing instruction, as shown in FIG.
It can be moved to another one of the intersections of the connecting line segment and the pattern. Also, if you give a pattern change direction change instruction,
The direction in which the pattern matching point is obtained is changed from the X direction to the Y direction in FIG. 5D. When the placement instruction is given, a placement process such as matching check between the pattern alignment mark and the pattern is performed (FIG. 5C).

The processing for this operation is shown in FIG. If the instruction issued by the user during the throwing operation is the placement operation instruction (S101 and S indicate steps, the same applies hereinafter), placement processing is performed (S108). On the other hand, if it is not the placement operation instruction but the pattern matching point change instruction (S10
2) Then, the next pattern matching point is searched (S103) and the pattern matching position is displayed (S107). If it is not a pattern matching point changing instruction but a pattern matching direction changing instruction (S10).
4), change the pattern matching direction flag 44 (S105),
The pattern matching position is displayed (S107). If it is a mere movement instruction, the thrown parts are moved (S106) and the pattern alignment position is displayed (S107).

Now, the contents of the pattern matching position display processing will be described with reference to the flowchart of FIG. First, a connection line segment between the thrown-in part 45 and the part located at the placement part counter 48 (P in the flow chart) on the part placement information table 43 is given as a connection information table 92.
Is searched for and set, and is set in the connecting line segment table 46 (S112). According to the pattern matching direction flag 44, a coincident point between the connecting line segment and the pattern is obtained, and a pattern matching marker is displayed on the arranged parts (S113). Next, the pattern alignment marker is also displayed at the position on the throwing part corresponding to the pattern alignment marker (S114). Then, a straight line is displayed between the corresponding pattern matching markers (S115).
This process is repeated by changing the placement part counter 48 from 0 to the end of the placed parts (S11).
1).

The processing steps of S113 and S114 function as a marker generating means for displaying a pattern matching marker as a pattern matching mark on the display 10 at a position where the connecting position and the pattern match.

The contents of the processing for obtaining the connecting line segment between one placement part and the throwing-in part are shown in the flowchart of FIG. The connecting line segment table 46 is held in the form of an array of connecting line segment data as shown in FIG. In the connecting line segment data, a set of a constituent point number of a placement part and a constituent point number of a throwing part are arranged in a row. First, the connection information of the throwing parts 45 is read from the connection information table 92 into the array TB of the work area 49 (S12).
1). Similarly, the connection information of the placement parts whose connection state is to be checked is read into the array T (S122). Further, a new data area is added to the connection line segment table 46 (S12).
3). B is the component point data counter in the throw-in part,
Let C be the configuration point data counter in the placement part. The B-th concatenation code of the array TB and the C-th concatenation code of the array T are compared (S126), and if the concatenation codes match, the constituent point number is added to the concatenation line segment data (S127). B
And C are changed, the points of the placement parts are compared and compared with the respective points of the thrown parts, and the connecting line segment table 46 is created.

The processing step of S126 functions as a connecting position determining means for obtaining a connecting position between a plurality of parts.

Next, the process for obtaining the pattern coincidence point will be described with reference to the flowchart of FIG. If there is no pattern matching mark data (S131), the pattern matching data closest to the starting point is calculated. Parts placement information table 43
Then, the arrangement position of the part P on the marker sheet is read and set to X and Y (S132). Further, the connecting line segment data of the part P and the thrown-in parts is read from the connecting line segment table 46, and the constituent point number of the starting point is set to PO (S133). Then, the coordinates of the points of the part P and the component point number PO are read from the shape information table 91,
Coordinates X and Y on the PO marker sheet are calculated (S134). From these, the pattern closest to the starting point of this line segment is calculated (S135) and set in the pattern alignment mark table 47 (S138). If the pattern alignment mark data already exists, it is read (S13
6) The position corresponding to the pattern line next to the current pattern number is calculated and obtained (S137) and set in the pattern alignment mark table 47 (S138).

Finally, the processing when an instruction to place the thrown parts is given will be described with reference to the flowchart of FIG. First, it is checked whether the pattern alignment mark position of the thrown-in part matches the pattern on the marker sheet (S141). If they do not match, an error message is displayed (S142), and if the user gives a forced instruction (S143), the placement is executed (S144).

The processing step of S141 functions as a pattern matching determining means for determining whether or not the pattern matching position stored in the pattern matching mark table 47 and the pattern match.

In this embodiment, the pseudo pattern is displayed on the marker sheet, but it need not be displayed.

[0033]

As is apparent from the above description, the marking device of the present invention holds connection information between parts in advance and displays a pattern matching marker which is a standard for pattern matching when throwing parts, At the time of arrangement, since it is determined whether the pattern alignment marker position matches the pattern, pattern alignment marking can be performed quickly and easily.
