Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic processing apparatus for processing a graphic created using a CAD function, and more particularly to a graphic processing apparatus capable of improving the processing quality by changing the processing order. The present invention relates to a processing method and an apparatus.

[0002]

2. Description of the Related Art In the production of a paper container or the like, graphic data designed by CAD is transferred to a processing device such as a plotter, a laser, a cutting die or the like, and processed into a final product shape. In this case, conventionally, graphic data designed by CAD has been passed to the processing apparatus in the same order. Therefore, if processing is performed in this order, useless positioning operation of the processing tool frequently occurs, resulting in poor processing efficiency. In order to solve this problem, the present applicant has proposed a graphic processing apparatus which changes the order of data so as to minimize the positioning operation of a processing tool as disclosed in Japanese Patent Application Laid-Open No. 6-242814.

[0003]

However, in the above-mentioned figure processing apparatus, since the processing order was changed only for the purpose of improving the processing efficiency, it was not satisfactory in terms of quality. The actual processing is performed by the processing equipment
This is performed in a state where the paper is fixed by a plurality of vacuums, that is, an air suction method using suction holes. For this reason,
If the outer side is cut first, suction of the portion that is no longer cut by vacuum will not be performed, and the suction area will be reduced, so that the displacement of the sheet will increase. The present invention has been made in consideration of the feature of the shift due to such a processing step, and by changing the processing order of the graphic data created by CAD, processing from the inner data is performed. It is an object of the present invention to provide a graphic processing method and apparatus capable of improving processing quality.

[0004]

In order to solve the above-mentioned problems, the invention according to claims 1 and 4 of the present application extracts graphic data necessary for processing and classifies the extracted graphic data for each processing type. The data of the same processing type is rearranged so that the outer data is processed later, and the data format is converted for the processing apparatus. According to the first and fourth aspects of the present invention, since the outer data is processed later for each processing type, the deviation is small, and as a result, a product with high processing accuracy is obtained.

According to a second aspect of the present invention, the step of rearranging data of the same processing type according to the first aspect of the present invention so that outer data is processed later is performed by using a pattern closest to the reference point. Searching the figure data starting from a point on the data and rearranging the outer data, and searching for the figure data starting from the point on the figure data closest to the end point of the outer data as the new starting point Rearranging the
It is realized by a process of reversing the processing order of all graphic data of the same processing type and exchanging the start point and the end point. According to the second aspect of the invention, the outermost graphic data is rearranged first, and then the inner graphic data is rearranged in order to set the point closest to the reference point as the search start point. Thus, by simply reversing the order of the processed data, the data can be rearranged so as to be processed easily from the inside.

A third aspect of the present invention is characterized in that, in the first aspect of the present invention, a step of extracting unnecessary graphic data after extracting graphic data necessary for processing is provided. According to the third aspect of the present invention, unnecessary data is removed before the change of the processing order, so that unnecessary data is not included in the processing of the change of the processing order. Can be manufactured.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram showing an embodiment of the graphic processing apparatus of the present invention. The figure processing apparatus shown in FIG. 1 is a figure creating apparatus 1 having a CAD function.
Arithmetic means 2 for receiving the graphic data created in step (1), processing the data and passing it to the processing device 4, and graphic data storage means for storing the graphic data created by the graphic creating device 1 and the graphic data processed by the arithmetic means 2 3 and a processing device 4 for performing processing according to the data processed by the arithmetic means 2.

The arithmetic means 2 is, in detail, a figure creating device 1
Alternatively, a graphic data extracting means 21 for extracting graphic data to be processed from the graphic data storage means 2, and a data deleting means 2 for deleting unnecessary data from the extracted graphic data.
2. To improve the quality, there are a data changing means 23 for integrating graphic data and changing the order, and a data converting means 24 for converting a data format for processing means.

More specifically, the arithmetic means 2 comprises a CPU and a memory of a personal computer, and each means 21 to 24 in the arithmetic means 2 functions according to a dedicated program stored in the memory. The graphic data storage means 3 is constituted by an external storage device such as a hard disk connected to a computer. As the processing device 4, a plotter, a laser processing device, a data output device to a punching die, or the like is used according to a use form.

Next, the processing operation of the figure processing apparatus will be described with reference to the flowchart of FIG. First, the graphic data extracting means 21 extracts graphic data from the graphic data storage means 3 in step S1. Subsequently, the graphic data extracting means 21 extracts data necessary for processing from the extracted graphic data, and stores the data in a work area of a memory (not shown) in the arithmetic means 2. Here, of the figure data,
The data required for processing is data for performing sewing, cutting, pen, and pressing, and the data not required for processing is data such as character strings and dimension lines. FIG. 3 shows the figure extracted at this time and its figure data. In the figure at the top of FIG. 3, a solid line indicates a cut and a dotted line indicates a pressed rule. Arrows are provided for convenience of explanation and are not attached to actual graphic data. This arrow indicates the direction of the graphic data, and the arrow side is the end point. The data in the lower part of FIG. 3 corresponds to the upper figure, and the leftmost serial number is given for convenience in order to correspond to the upper figure and identify the processing order. 2 from left
The data in the column indicates the type of processing, and includes a sewing machine for processing, a cut for cutting with a cutter, a pen for writing a line with a ballpoint pen, etc., and a ruled line for making a mark for bending. There are types. In this example, for convenience of description, there are two types of cutting and pressing. The third and fourth columns are the X and Y coordinate values of the start point of the line segment, respectively, and the fifth and sixth columns are the X and Y coordinate values of the end point of the line segment, respectively. In FIG. 3, the origin is defined at the lower left of the figure, and the horizontal axis is the X axis and the vertical axis is the Y axis.

Next, in step S2, the data deleting means 22
Deletes unnecessary data from the extracted data.
The data to be deleted is determined based on its length, and those below the set value are deleted. If the setting value is set to “5”,
Since the data of the processing order (14) shown in FIG.
Will be deleted. In the process of creating a graphic by CAD, unnecessary data may be left by mistakenly adding an extra point or intentionally making a mark for a mark in the process. Data can be deleted. In this example, the set value is set to “5” in this coordinate system. However, since it is actually aimed at deleting a minute point, when output to paper or the like, 0.001 m
The setting is made so that the thing less than about m is deleted.

When the unnecessary data is deleted, in step S3, the data changing means 23 rearranges each line segment data according to the processing type. Here, only sorting by processing type is performed, and sorting is not performed within data of the same processing type. Therefore, the data is simply rearranged in the order of the cut data and the pressed data. FIG. 4 shows the state after the sorting. Compared to FIG. 3 before sorting, the processing order (4), (1
The data of the pressed rule that was 0) is in the processing order (12), (13).

Next, in step S4, the data changing means 2
3 integrates the line segments that can be integrated. The line segments that can be integrated are line segments that are on the same straight line. In FIG. 4, the line segments in the processing order (2), (4), (9) parallel to the X axis,
Similarly, the processing segments (3), (8), and (10) which are parallel to the X axis correspond to the line segments. The processing order (2), (4), (9) line segments are integrated into one,
It becomes the line segment of the processing order (2). The direction of the line segment in the processing order (2) after integration is the same direction as the line segment in the processing order (2) before integration.
Similarly, the line segments in the processing order (3), (8), and (10) are integrated as the line segment in the processing order (3). FIG. 5 shows the figure after the integration.

In step S5, the data changing means 23
In order to minimize the movement of the processing tool, the processing order is changed so that data connected to each other can be processed by one-stroke movement. Details of the processing in step S5 are shown in the flowchart of FIG. Step S5 in FIG.
In step 1, the data change means 23 detects the start point.
At this point, since the graphic data is arranged for each processing tool as shown in FIG. 5, the work is performed from the “cut” arranged first. First, a point closest to the reference point, that is, the point at the coordinates (0,0) is searched for in the data of “cut”. Then, point A (100, 100) is detected as a processing point.

Next, in step S52, a line segment is selected. A line segment having the detected processing point as an end point is selected as data in the next arrangement order. If there are two or more line segments having processing points, priorities are determined in advance, and processing is performed according to the priorities. For example, in this example, the one having the smallest difference between the X-coordinate of the processing point and the other end point of each line segment is selected.
In the example of FIG. 5, the line segment having the point A as the end point has two types of data of the processing order (1) and the data of the processing order (3). The data in the processing order (1) with the smaller difference is selected. Alternatively, a setting may be made so that the one with the lower processing order number is simply selected with priority.

Next, in step S53, an end point of the selected line segment is set as a processing point, and another line segment having this processing point as an end point is searched. If there is a corresponding line segment, the process returns to step S52 to perform a line segment selection process. If there is no corresponding line segment, it means that there is no longer any line segment that can be moved with one stroke, and the process proceeds to step S54. In the example of FIG. 5, if the end point (100, 160) of the data in the processing order (1) is a processing point, there is only one line segment having the processing point as an end point, and thus there is only one data in the processing order (2). The data of the processing order (2) is selected. However, the starting point is (100, 160)
Therefore, the end point is (220, 160), and the direction of the line segment is reversed. In this way, the processing order (7), the processing order (3)
Is selected, and the graphic data is rearranged as shown in FIG.

When the data of the processing order (4) in FIG. 7 is selected, the processing point is the point A (0,0) which is the end point, but the processing order is a line segment having the processing point A as an end point. (1)
And the data of the processing order (4) have already been selected, so that there is no other line segment to be connected, and step S5
Proceed to 4. In step S54, it is searched whether there is unselected data with the same type of processing tool. Here, if there is no unselected data, the processing for changing the processing order in step S5 ends. If unselected data remains, the process returns to step S51, where the point closest to the end point of the data that was last selected is selected as a new start point, and change processing is performed on the remaining data. . In the example of FIG. 7, the point B (140, 115) closest to the end point A is selected as a new start point from the remaining data of the processing orders (5), (6), and (7). Thereafter, the processing of steps S52 and S53 is repeated in the same manner as when processing is performed from the start point A, and the data of the processing order (5), (6), and (7) is changed as shown in FIG. Since there is no new data having the end point B of the data in the processing order (7) as an end point, the process proceeds from step S53 to step S54 to search whether there is unselected data with the same type of processing tool. Since no data of the same type of processing tool “cut” remains, step S5 is ended.

When the processing for the data of the processing tool "cut" is completed, it is checked in step S6 in FIG. 2 whether or not the processing for all the processing types of data has been completed. Here, since the data of “pressed rule” remains, the process returns to step S4 to perform the integration process for the line segments that can be integrated.
In this example, as shown in FIG. 8, there is no "pressed rule" data that can be integrated, so the process proceeds to step S5, and processing for changing the processing order is performed. In step S51 of the flowchart in FIG. 6, the point C closest to the reference point is detected as a start point. Since the line segment having the start point C as the end point is only the data in the processing order (8), the selection is made with the start point and the end point reversed. FIG. 9 shows the state of the graphic data at this time. Since there is no data having the end point of the data of the processing order (8) as an end point, step S
Proceed to 54. Since unprocessed "pressed rule" data still remains, the process returns to step S51 to detect the start point D.
The line segment starting from the point D is selected as it is as the data of the processing order (9). Since there is no other line segment having the end point of the data in the processing order (9) as an end point, and there is no unprocessed "pressed ruled" data, step S5 is ended.

Returning to the flowchart of FIG. 2, since there is no processing tool data other than "cut" and "pressed rule" in this example, the process proceeds to step S7. In step S7, with the data of all the processing tools included, the processing order of the graphic data is reversed, and the start point and end point of each line segment data are reversed. FIG. 10 shows the state of the graphic data in which the processing order is finally changed in this way. Step S8
Then, this graphic data is stored in the graphic data storage means 3,
In step S9, the graphic data is converted by the data conversion means 24 into a format suitable for the processing device 4. In step S10, the converted graphic data is transferred to the processing device 4 to process the product.

In step S10, the processing apparatus 4 shown in FIG.
In the case of processing the data shown in (1) as a product, first, the data is processed in accordance with the data in the processing order (1) and the data in the processing order (2) using the processing tool “press rule”. Next, a cutting process is performed according to the data of the processing order (3), (4), and (5), instead of the processing tool being “cutter”. Subsequently, a cutting process is performed by the processing tool “cutter” in accordance with the data of the processing order (6), (7), (8), and (9). As shown in the example of FIG.
After processing (3), (4), (5) of the same processing tool, (6),
In order to process (7), (8), and (9), that is, after processing the inner data, the outer data is processed, so that the displacement of the paper is small, and as a result, the quality is improved.

[0021]

According to the present invention, graphic data necessary for processing is extracted, the extracted graphic data is classified for each processing type, and data of the same processing type is processed so that outer data is processed later. Since the data format is changed for the rearrangement and the processing apparatus, a product with less deviation and high processing accuracy can be obtained. Furthermore, the step of rearranging data of the same processing type so that the outer data is processed later is performed by searching for graphic data starting from the point on the graphic data closest to the reference point and arranging the outer data. Reordering, reordering the inner data by searching for the graphic data using the point on the graphic data closest to the end point of the outer data as a new starting point, and reversing the processing order of all graphic data of the same processing type And the step of exchanging the start point and the end point is realized, so that the order in which the graphic data can be processed from the outside can be changed.
