Description

[0001]
[Industrial applications]
The present invention relates to a graphic processing apparatus, and more particularly, to a graphic processing apparatus for processing a product based on graphic data of a product (for example, a paper container) designed by CAD or the like.
Today, with the spread of CAD, anyone can easily design products. However, there are many cases where the quality of a design cannot be determined without actually processing and outputting a product. Therefore, it is desired to provide a graphic processing apparatus capable of easily processing and outputting a product designed by CAD or a prototype thereof.
[0002]
[Prior art]
Conventionally, graphic data designed by CAD or the like has been translated into control data of a processing machine in the same order and added to the processing machine. However, since the CAD graphic data does not take the actual processing order into consideration, if the data is added to the processing machine in the same order, useless positioning operations of the processing tool frequently occur. In addition, many products require multiple types of processing (for example, cutting, ballpoint pen, pressing, etc.). If processing is performed according to graphic data that does not take such points into consideration, processing tools will be changed at random and processing efficiency will increase. Is significantly reduced.
Conventionally, an operator has redesigned control data of a processing machine based on CAD design data. However, this work requires knowledge of machining, requires a great deal of time and effort, and may cause a design error.
[0003]
[Problems to be solved by the invention]
As described above, conventionally, the graphic data designed by CAD was added to the processing machine in the same order, or the operator redesigned the processing control data separately, resulting in extremely low processing efficiency and error. There was also a possibility.
An object of the present invention is to provide a graphic processing apparatus capable of easily and efficiently processing and outputting a product or a prototype based on graphic data designed by CAD or the like.
[0004]

[0005]
[Action]
In the graphic processing apparatus according to the present invention, the input means inputs graphic data of a product designed by CAD or the like. The creating means creates the graphic data for processing so as to minimize the positioning operation of the processing tool by an operation for changing the arrangement of the input graphic data. Preferably, the creating means performs an operation of changing the arrangement of input graphic data collectively for each type of processing tool such as cutting, ballpoint pen, and pressing. Then, the conversion means converts the created processing graphic data into control data of the processing apparatus. Therefore, for example, graphic data of a product assembled in an arbitrary order for the sake of design is changed to efficient graphic data for processing in consideration of a processing tool and a processing order, thereby improving processing efficiency.
[0006]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a block diagram of a graphic processing system according to an embodiment. In the figure, reference numeral 1 denotes a graphic creation / editing apparatus (for example, CAD) connected to the outside; 2 denotes a graphic processing apparatus of the embodiment; Is a data storage device for storing graphic data and the like of a product designed by CAD1.
[0007]
Reference numeral 5 denotes an arithmetic unit constituted by a memory and a CPU (not shown), and realizes the following various functional blocks. That is, reference numeral 6 denotes input means for reading graphic data to be processed from the data storage device 4. Reference numeral 7 denotes an extracting means for extracting graphic data necessary for processing a product from the read graphic data. Numeral 8 denotes a creating means for creating the graphic data for processing so as to minimize the positioning operation of the processing tool by changing the arrangement of the extracted graphic data. Reference numeral 9 denotes a conversion unit that converts the created graphic data for processing into control data for the processing apparatus 10. Reference numeral 10 denotes a product processing apparatus using a laser, a cutting die, or the like. Hereinafter, the processing output processing of the product based on the design drawing data of the CAD 1 will be described in detail.
[0008]
FIG. 2 is a flowchart of the graphic processing according to the embodiment.
In step S1, the input means 6 reads out the corresponding design drawing data from the data storage device 4 and stores it in a work area (not shown) in the arithmetic unit 5. In step S2, the extracting means 7 extracts graphic data necessary for processing the product from the design drawing data stored in the work area.
This extraction process will be described with a simple example of FIG. In FIG. 4A, graphic data necessary for processing a product out of the design drawing data stored in the work area is composed of line segment data (a) to (g). Data (character string “100”) is attached. 4B shows an example of storing the design drawing data of FIG. 4A. From left, “L” in column 1 is a line segment, “C” is a character, and “1” in column 2 is “1”. Indicates a graphic line, "2" indicates a dimension line, "1" in column 3 indicates a solid line, and "2" indicates a broken line. Further, column 4 represents the number of subsequent data. For example, when column 1 is a line segment L, the subsequent four data represent the XY coordinates of the start point and end point of the line segment, respectively. When the column 1 is a character C, the following eight data represent the XY coordinates of the start point of the character, the height, the width, the space between characters, the rotation angle, the number of characters, and the character code. Then, the extracting means 7 extracts the graphic data (a) to (g) of the column 2 = 1 (graphic line) from the design drawing data stored in the work area, thereby extracting the graphic data necessary for processing the product. I do.
[0009]
Next, in step S3, the creating means 8 first determines whether or not there is a type of processing. The type of processing refers to the type of processing method (processing tool) such as, for example, ballpoint pen, pressing, and cutting. In this embodiment, column 3 = 1 (solid line) of the graphic data is used for cutting, and column 3 = 2. (Dashed line) corresponds to the press working, and column 3 = 3 corresponds to the ball-point pen working.
The creation unit 8 automatically determines whether or not there is a type of processing by basically checking the contents of the column 3 of all the graphic data extracted by the extraction unit 7. Therefore, the graphic data (a) to (g) of FIG. 4B includes two types of graphic data, column 3 = 1 (cut) and column 3 = 2 (push). No. 8 determines that there is a type of processing, and the flow proceeds to step S4. In step S4, for example, first, graphic data of column 3 = 3 (ballpoint pen) is collected in the arrangement order, and these are set in the work area. In this example, since there is no graphic data of the ballpoint pen, graphic data (g) of the next column 3 = 2 (push) is collected and set in the work area.
Instead of the above, the operator may forcibly specify whether or not there is a type of machining from CAD1. In this case, if the operator specifies that there is no type of processing, the creating unit 8 determines that there is no type of processing regardless of the contents of the column 3 in the graphic data. Accordingly, the flow proceeds to step S5, and all the graphic data (a) to (g) extracted by the extraction means 7 are set as processing target data in the processing described later in the same arrangement order.
[0010]
FIG. 5 shows an example of setting graphic data according to the presence or absence of a processing type. FIG. 5A shows a case where there is no machining type from CAD1, and all the graphic data (a) to (g) are set in the same arrangement order. FIG. 5B shows a case in which the creation means 8 determines that there is a type of processing. In this case, first, the figure data (g) of the pressing is set, and the processing after step S6 is performed. Thereafter, the graphic data (a) to (f) of the cut are set, and the processing after step S6 is performed.
Returning to FIG. 2, in step S6, the creating means 8 performs necessary pre-processing on the previously set graphic data in order to facilitate the rearrangement processing described later.
Some examples of this preprocessing are shown in FIG. In FIG. 6A, when a plurality of line segment data of the same processing type has an overlapping portion with each other, the overlapping portion is separated, and one line segment data of the overlapping portion is deleted. The same applies to a case where a plurality of pieces of curve data of the same processing type have overlapping portions. However, if the line segment data or the curve data of different processing types (for example, cutting and pressing) have overlapping portions, the above processing is not performed. Thereafter, in FIG. 6B, when a plurality of line segment data of the same processing type can be combined into one line segment data, these are combined into one line segment data. The same applies to a plurality of curve data of the same processing type. However, line segment data or curve data of different processing types are not combined. By performing the preprocessing described above, graphic data is unified in advance so that each processing tool does not perform useless overlapping processing.
[0011]
Returning to FIG. 2, in step S7, the creating means 8 creates processing graphic data such that the positioning operation of the processing tool is minimized by an operation of changing the arrangement of the graphic data subjected to the preprocessing.
FIG. 3 is a flowchart illustrating details of the rearrangement process according to the embodiment.
In step S21, the starting point of the processing is determined. The start point is determined, for example, by selecting one of graphic data having an end point at a position closest to the current position of the processing tool. In step S22, the first graphic data is stored in the direction from the start point. In step S23, it is determined whether there is unprocessed graphic data. If there is no unprocessed graphic data, the process ends and the process returns to the main routine of FIG. If there is unprocessed graphic data, it is determined in step S24 whether the end point of the currently processed graphic data has graphic data to which the start point or the end point can be connected. When there is no connectable graphic data, it is necessary to exchange a processing tool or perform a positioning operation, and the process returns to step S21 to determine a new processing start point. If there is graphic data that can be connected, it is determined in step S25 whether there is a plurality of graphic data that can be connected. If it is singular, the process returns to step S22 to set the current position as the starting point and store the graphic data in the direction from the starting point. If there is more than one, branch processing is performed in step S26. That is, in this branching process, for example, when there is no further branch ahead of a plurality of connectable graphic data, the shortest graphic data among the plurality of graphic data is selected and the current point is set as the starting point. If there is a further branch ahead of the plurality of graphic data, the shortest graphic data is selected from the plurality of graphic data and the current point is set as the starting point. In this way, by selecting the shortest graphic data first, the return (positioning) of the processing tool that occurs later can be minimized.
[0012]
Returning to FIG. 2, in step S8, the processing graphic data created by the rearrangement operation is stored in the work area. In step S9, it is determined whether there is a machining type. If there is a processing type, it is determined in step S10 whether or not the above processing has been completed for all processing types. If not completed, the process returns to step S4 to set graphic data of the next processing type and create graphic data for the processing. As described above, when there are machining types, machining graphic data that minimizes the positioning operation of the machining tool is collectively created for each machining type, thereby improving machining efficiency.
[0013]
FIG. 7 is a diagram showing a specific example of the above-described rearrangement processing. FIG. 7A shows a case where no machining type is used from CAD1. For example, assuming that the initial coordinates of the processing tool are (0, 0), the line segment data having the closest end point to them is (c) and (f). Therefore, for example, when the line segment data (c) is selected, the start point coordinates are (100, 130) and the end point coordinates are (100, 180). Next, since there is only (e) the line segment data which can be connected to the end point coordinates (100, 180), the line segment data (e) is arranged next to the line segment data (c), and the start point coordinates are (100, 180). 180) and the end point coordinates are (120, 200). Hereinafter, line segment data (a), (d), and (b) are similarly rearranged. With respect to the line segment data (f), the direction in which the processing tool is moved is reversed if the line segment data (f) remains as it is. 130). In this example, since there is no machining type, the line segment data (g) of the push follows the determination with a new start point.
FIG. 7B shows a case where it is determined that there is a machining type. In this case, the graphic data processed in the route of the first steps S4 to S8 in FIG. 2 is only the pressed line segment data (g). The graphic data processed in the route of the next steps S4 to S8 are line segment data (a) to (f) of the cut. Since the coordinates of the end point of the processing tool at the time of processing the line segment data (g) are (200, 170), the line segment data (b), ( d) and (f) exist. Therefore, for example, (b) is selected as line segment data that satisfies the condition that both end points are close to the coordinates (200, 170). The direction in which the processing tool is moved may be any direction, but in this example, the direction-(b) is selected. As a result, the first line segment data (b) is rearranged to-(b), that is, the start point coordinates are rearranged to (200, 150) and the end point coordinates are rearranged to (200, 190). Next, the line segment data that can be connected to the end point coordinates (200, 190) is (d), and the direction in which the machining tool is moved is reversed, so that the line segment data (d) follows the line segment data- (b). ) Are arranged, and the start point coordinates are rearranged to (200, 190) and the end point coordinates are rearranged to (190, 200). Hereinafter, the line data is similarly rearranged in the order of-(a),-(e),-(c). Since the line segment data (f) is the same as the direction in which the machining tool is moved, it is arranged as it is after the line segment data- (c).
[0014]
Returning to FIG. 2, in step S11, control data for controlling the processing apparatus 10 is created based on the rearranged processing graphic data.
This processing example will be specifically described with reference to FIG. FIG. 8A shows a case where the machining type is eliminated by CAD1. When the conversion means 9 reads the first graphic data (c) in FIG. 7A, the conversion means 9 first detects the column 3 = 1 (cut) and converts it into an instruction to set the corresponding tool (TOOL) 1. I do. Further, the command is converted into a command for positioning (MOVE) the tool 1 at the start point coordinates (100, 130) of the graphic data (c), and then a command for cutting (DRAW) the tool 1 to the end point coordinates (100, 180) is provided. Convert. Next, when the second graphic data (e) is read out, it is converted into an instruction to cut and move the tool 1 to the end point coordinates (120, 200) as it is. Thereafter, the conversion is performed in the same manner, and when the sixth graphic data (f) is read out, the command is converted into an instruction to cut and move the tool 1 to the end point coordinates (100, 130). Finally, when the seventh graphic data (g) is read, it is converted into an instruction to set the corresponding tool (TOOL) 2 because the column 3 has changed to 2 (push). Further, it is converted into a command for positioning the tool 2 at the start point coordinates (100, 170), and then converted to a command for pushing and moving the tool 2 to the end point coordinates (200, 170). FIG. 8B shows a case where it is determined that there is a machining type, and the conversion algorithm is the same as described above.
[0015]
Returning to FIG. 2, in step S12, the processing machine control data obtained as described above is added to the processing device 10, and a product corresponding to the graphic data for processing is processed and output.
As described above, according to the present embodiment, efficient processing can be performed without unnecessary positioning of the processing tool. Moreover, the graphic data of CAD1 does not need to be specially created for processing, and the graphic data of the product at the time of design can be used as it is. Further, since no modification is made to the original design data of CAD1, the original design data is not affected at all. Thus, a product designed by CAD1 or its prototype can be easily processed and output.
[0016]
【The invention's effect】
As described above, according to the graphic processing apparatus of the present invention, since the processing data is created directly from the graphic data designed by CAD or the like, the operator does not need to redesign and input the processing data. Therefore, no error occurs. In addition, since a product is automatically processed and output using a cutting plotter or the like based on the obtained processing data, useless operation is reduced, and processing time can be reduced and efficiency can be improved.
