Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called punching machine, and more particularly to a panel punching technique for reflecting a design on a panel.

In general, a panel is one of building materials,
Used for balconies, fences, etc. When a panel is used as a building material, it has a large surface area and is likely to be exposed to the human eye. Therefore, consideration for decorativeness is more important than other building materials. In particular, with the enhancement of social capital in recent years, aesthetics are also required for buildings used by the private sector. Due to such social demands, higher decorativeness is required for the panel. Therefore, a technology for freely forming a design on a panel is required.

[0003]

2. Description of the Related Art Conventionally, in order to enhance the decorativeness of a panel, a panel punching device has been used to provide a regular array of holes on the surface of the panel.

FIG. 20 shows how the conventional panel is manufactured. The panel P ₀ is made of a flat plate such as an iron material having a predetermined thickness. The mold 101 plays an important role in determining the pattern to be provided on the panel P ₀ . A plurality of punches 102 are provided on the punching surface of the die 101. The punching operation for the panel P ₀ is performed by pressing the die 101 in which a plurality of punches 102 are regularly arranged with a predetermined pressure. When the width of the panel P ₀ is wider than that of the mold 101, the operation of feeding a predetermined amount of the panel P ₀ for each pressing operation is repeated to form a hole in the entire panel P ₀ .

The panel feeding device 105 outputs a control signal for feeding the panel P ₀ . This control signal is, for example, frequency information, and is converted into the number of revolutions by the motor 104. The motor 104 is directly connected to the roller 103,
A torque is generated by the control signal to convey the panel 100 by a constant amount. In many cases, the panel feeding operation also serves as the panel material rolling operation.

Therefore, in reality, only one type of mold was to be manufactured. This means that only the types of panels that can be mass-produced can be produced, and the conventional panel punching device is not suitable for producing a large number of small-volume panels.

Further, according to the conventional panel punching device,
Even if the holes are arranged in a pattern within the range of the die-cutting area, the panel is usually manufactured by alternately repeating the feeding operation and the punching operation. It was undeniable that the holes were simply repeated according to the above design, and that the panel pattern was monotonous as a whole.

(I) First Example The first example is an application of the invention described in claims 1 to 11. Description of Configuration i) System Configuration FIG. 1 shows the overall configuration of an embodiment of the present invention.

As shown in FIG. 1, the entire system comprises a punching information generating device 100 for generating punching information, a punching device 200 for performing a punching operation, and a panel feeding device 300 for conveying a panel. The following is a description of each device.

The panel is not limited to a metal panel, but can be changed to synthetic resin, glass, plastic, rubber or the like. ii) Drilling Information Generating Device As shown in FIG. 1, the drilling information generating device 100 is mainly composed of the microcomputer 10. The microcomputer 10 uses an image generation circuit 20 that captures an image from an external device and processes the image, a memory 21 that is a temporary image storage area, and hole array information for actually punching the generated image data. And an array allocation circuit 22 for conversion. The scanner 24 reads a design from an arbitrary sheet and uses it as image data.

The microcomputer 10 performs the image generating operation and the array allocating operation, which will be described below, by a program, but they may be configured by hardware. The keyboard 25 transmits a user's operation command to the microcomputer 10. The mouse 26 is used not only for transmitting a user's operation command to the microcomputer 10 but also as an input means when creating an image. The disk 27 is a storage medium for storing images and punching information at another place, and for reading data created at another place by a microcomputer connected to the punching device. The hard disk 28 stores a program and also stores a large amount of image data. The monitor 29 displays image information. The adapter board 30 includes a large-diameter hole port 31 for switching a large-open hole (hereinafter referred to as a large-diameter hole) and a small-diameter hole port 32 for switching a small-open hole (hereinafter referred to as a small-diameter hole). Has two output ports.

In the present embodiment, the adapter board 30 is used by being inserted into a so-called expansion slot of the main body of the microcomputer 10, but it may be provided at the input stage of the main body of the punch device 200. Each port is provided with terminals for the required number of punches (for example, 100 for each).

The microcomputer 10 is a punch device 2
The position information supplied by the reciprocating motion control circuit 70 of 00 is input to the external interrupt terminal. The following modifications can be made to the punching information generating device.

A camera can be used as the image input means. In other words, if a video camera is used as the input source and is input to the image generation circuit via a video signal-to-pixel signal converter, if it is a normal landscape, a person, etc. Can be reflected.

As the array allocation circuit, instead of arranging a fixed pattern in each area, an arbitrary pattern having an appropriate aperture area ratio may be automatically generated according to the magnitude of luminance information or color information. . This eliminates the need for array allocation operation and facilitates the panelization of multivalued images.

Iii) Punching device The punching device 200 roughly includes a reciprocating motion control system that controls the reciprocating motion of the entire punch, and an air pressure control system that controls whether the punch is valid or invalid.

The reciprocating operation control system includes a reciprocating operation control circuit 70 for controlling the reciprocating operation and a wire 72 with a weight 71.

By adjusting the length of each punch so that the panel P is punched only when the punch is in the extruded state when pressed, it is possible to control whether or not to punch the hole only by controlling the switch signal. The control mechanism for these punches is a known technique.

The punch rows are not limited to two rows, and one row, three rows, four rows, and more rows may be provided depending on the amount of punching information that can be simultaneously supplied by the punching information generating means. You may provide the number. By adjusting the die pitch by making the punch diameter of each row different, holes having different opening diameters can be provided on the same or different rows of the panel.
Further, as shown in FIG. 1, a punch and its driving means may be provided on the entire surface of the die so that all punching information can be reflected at one time.

The switch is not limited to the control by the solenoid valve, and other valve means such as an electric switch may be used as long as the push-out / pull-in of the cylinder can be controlled. As the medium, water pressure or hydraulic pressure can be used in addition to air pressure. That is, any information that can reflect the electrical switch information as valid / invalid of punching can be used.

The punching device is not limited to the punch, but any device capable of making a hole in the panel, such as drilling, electric discharge machining, laser beam machining, electrolytic machining, etc., can be applied. When these processing tools are used, instead of providing the perforation means in a single horizontal row, the table on which the panel is placed is configured to be movable in the X or Y direction along with the scanning of the perforation information.

A device that drives an O circuit can be considered.

In addition to the stepping motor, any other motor can be used as a driving servo motor as long as it has excellent response characteristics, large output, high rotatability, maintainability, and life. For example, a DC control motor may be used, and the motor driver 84 may perform frequency-amplitude conversion and drive. Although the interrupt signal is used as the output timing, a timer may be provided inside the function generating circuit 82. The control characteristics are not limited to triangular drive and trapezoidal drive, and can be appropriately changed by designating a function suitable for control.

The image generation circuit 20 displays a menu or the like on the monitor 29 (for example, a display example is shown in the upper part of FIG. 8A). When the user sets the design of "Kamome" on the scanner 24 and selects "I / O" on the menu screen to specify the scanner input (step S30: YES), the image generation circuit 20 reads the image from the scanner 24 ( Step S31).

If the scanner 24 generates pixel information corresponding to the luminance, the design of the "seagull" shown on the paper is binarized or further multivalued according to the luminance distribution, and read. It is stored in the memory 21. Scanner 24
If is corresponding to the color information, the color information is also stored in the memory 21 in accordance with the color distribution of the design. This work is
It acts in the same way that the regionalization circuit 22 works. When the pattern is read in multiple gradations (for example, 16 gradations, 256 gradations, etc.), the gradation of the gradation is reduced by the image processing program (for example, it is decreased to 2 gradations, 4 gradations, etc.). Processing may be performed.

When processing the read image data (step S33: YES), the user selects "correction" from the menu. As image processing, known image processing is used to enlarge / reduce / rotate / reverse / move the original image.

You can also draw using. Here, the user
4 color bars (areas A _{1 to} A ₄ ) under the design of "Kamome"
Shall be drawn.

As a result of the above operation, it is assumed that the image as shown in FIG. 8A is read and processed. Here, the design is quaternarized and regions A _{1 to} A ₄ having four shades are formed. Furthermore, when inputting characters (step S3
2: YES) "OP" (option) is selected, and the user can input characters from the keyboard 25.

Next, the pattern of the array of holes to be actually used for panel processing is determined. When creating a completely new pattern (step S35: YES), the user selects "mode" from the menu and sets a new pattern with the mouse 26 or the like. If a preset pattern is used, the pattern number may be selected. When a new pattern is created (step S37: YES)
Is registered in the pattern (step S38). In this embodiment, two types of holes, a large-diameter hole with a large opening and a small-diameter hole with a small opening, are used, so that at least 2 ² = 4 types of patterns of simple arrangement can be obtained. The pattern is further increased by making the hole array periodic. Here, the user allocates in accordance with the four shade areas of the existing four pattern designs.

FIG. 8B shows the result of this operation.
The display of the allocated perforation information is shown in place of the original image of (A). In the display example shown in FIG. 8B, one having a large dot diameter corresponds to a large diameter hole, and one having a small dot diameter corresponds to one small diameter hole. A pattern having a large opening area due to holes is arranged in a portion having low brightness, and a pattern having a small opening area is arranged in a portion having high brightness. As a result, FIG.
As shown in (B), four patterns (D _{1 to} D ₄ ) are arranged.

I of the disk 27, the hard disk 28, etc.
When it is desired to register the original image data or the like in the I / O device (step S39: YES), the data is output to the corresponding I / O device and the data is saved.

When the processing is to be ended (step S41: Y
ES) ends the program. When the process is not completed (step S41: NO), the menu is awaited. To perform punching operation, select "I / O" from the menu and specify port output.

Ii) Punching process When the user selects "I / O" from the menu and sets punch output, the punching process starts. Hereinafter, description will be given based on the flowchart of FIG. Usually, image production and actual panel production are performed in different sites. It is also conceivable that the image data input and drawn at the production site is temporarily stored in the disk 27, and the same data is read out again to another microcomputer at the panel production site for use (step S4). When the image data and the punching information data stored in the disk 27 are read (step S4: YES),
The data is read from the disk 27 (step S
5).

In the captured image data, the aspect ratio of all data does not necessarily match the aspect ratio of the panel. for that reason,
The image is divided in the division mode, and punching information is output to the panel for each divided unit, or a window is set inside the image data and only the range of the window W is output to the panel. A window is used here. Step S6
Then, the window W is used to specify the range to be actually punched for the read punching information. In FIG. 8 (B), the window W is set for the perforation information display of the design of "Seagull".

In step S7, parameters are set according to the environment actually used. An example of this parameter setting is shown below. [Parameter setting example] Item name Input numerical value example Number of X-direction punches 200 Number of Y-direction punches 200 Number of X-direction punch pitches [mm] 5.000 Number of Y-direction punch pitches [mm] 5.000 Number of X-direction divisions 3 Number of Y-direction divisions 3 Punch diameter (large diameter hole) [mm] 10.0 Punch diameter (small diameter hole) [mm] 5.0 Material length X [mm] 1000 Material length Y [mm] 1000 Division mode 0 Punch mode 3 With the above parameters The panel material insertion direction is defined as the X direction, and the extending direction of the rows of punches at right angles thereto is defined as the Y direction. The number of punches is the maximum number of punches, the punch pitch is the distance between holes, the number of divisions is how many the whole pattern is divided, the punch diameter is the diameter of the punch, that is, the opening diameter of the hole. The material length is a dimension of the material, the division mode is a division method for division, and the punch mode is a selection column of a registered pattern to be reflected in each area. These parameters can be appropriately selected by selecting "mode" from the menu of the punching information generation program of the microcomputer 10. With the above settings,
You can set the holes to be used and the arrangement state. In the present embodiment, the pitch between the large diameter holes and the pitch between the small diameter holes are made equal. The row of large diameter holes and the row of small diameter holes are offset by half the pitch.

In step S8, the punch device 20
0, the power of the panel feeding device 300 is turned on, and the user turns on the power of the entire system to start the system operation.

At step S9, the microcomputer 1
0 waits for a feed signal to be input as an interrupt signal from the punch device 200. The punch device 200 can provide information according to the posture when the entire punch row is reciprocated. For example, the state in which the panel row is most raised is set to 0 °, and the state in which the panel row is most lowered is set to 180 °, and the angle state in each operation can be encoded and output. Stable arbitrary angle condition (for example, 240 °) with the punch completely pulled out from the panel
Then, it is also possible to set to output a predetermined pulse signal. The latter method is chosen here. The pulse signal is sent to the punching information generating device 100 and the panel feeding device 300, and is used as a timing signal (feed signal) for punch control.

When an interruption is caused by the feed signal (step S9: YES), punch control is performed. At the same time, in the panel feeding process of the panel feeding device 300, which will be described later, the panel P has a predetermined amount (half the punch pitch)
Only in the X direction.

Therefore, the drilling information generation device 1 is larger than the small diameter port 32.
Column ahead of the information sent to the diameter hole port 31 by the relative distance D
Need to supply information.

The punching information generating device 1 makes the information in the window W serial information column by column and the adapter board 3
Supply 0. Each port in the adapter board 30 latches this serial information and outputs it as parallel switch information. It may combine a shift register and a buffer. In addition, a PIO (parallel I / O LSI) for a microcomputer is used for each port, and I / O
You may output. Further, the punching information may be sent to the punching device as serial data or code data and distributed to each solenoid valve by an adapter provided at the input stage of the punching device.

Now, the adapter board 30 sends one line of data to the small diameter hole port 32 (step S10). For example, from (r ₁ , l ₆ ) to (r ₁₃ ,
Data up to l ₆ ) are sent. When the holes in the corresponding row are valid in the small diameter hole port 32 (step S11: Y
(ES) The bit is turned on (step S12). 1
When the data of all the lines have not been rewritten (step S13: NO), the next hole is checked (step S14).

When the data of one line is completed (step S13: YES), the information of one line of the large diameter hole is loaded (step S15). As described above, the punching is performed with the large-diameter hole delayed by the distance D with respect to the small-diameter hole. Therefore, in the example of FIG. 9, (R ₁ , L ₂ ) to (R ₁₄ , L ₂ ) in the second row are punched.
The data up to is sent to the large hole port 31. When the 1-line information of the large-diameter hole is completed by reflecting the same on the 1-line information of the small-diameter hole (step S18), all terminals are loaded (step S20), and output information is output to each solenoid valve of the punch device 200. Sent to. Each solenoid valve performs a cam pushing-out operation and a pulling-in operation according to ON / OFF information of the corresponding terminal, and new punching information is reflected in the punching-in pulling operation. The punching device 200 punches under the control of the reciprocating motion control circuit 70, and the panel P is provided with holes corresponding to the small diameter hole information on the sixth row and the large diameter hole information on the second row at the same time.

After the boring operation is completed, the flywheel of the control circuit
When 73 returns to the 240 ° position, the reciprocating motion control circuit 7
0 makes the sending signal valid (for example, L level). Drilling
The information generation device 100 receives this by an interrupt and restarts.
Repeat the steps from step S9. The next action is

The operation from step 10 to step 21 is repeated
It

When the line for the large diameter hole in the 15th row is finished (step S21: YES), the punching operation is finished. iii) Description of Drilling Information FIG. 10A shows drilling information of the small-diameter hole on the sixth row and the large-diameter hole on the second row described above. FIG.
(B) shows the drilling information for the small diameter hole on the seventh row and the large diameter hole on the third row to be loaded in the next punch. In each case, the upper row is drilling information loaded into the large diameter hole port 31, and the lower row is drilling information loaded into the small diameter hole port 32. The numbers are the numbers of bits (terminals), that is, the order of punching.

In FIG. 9, small-diameter holes are arranged all over the window W. Therefore, the dot information of the columns l ₆ and l ₇ of the small diameter holes in the _6th and _7th rows are all turned on. FIG.
Also in 0 (A) and (B), all bits are “ON”.

In FIG. 9, the large diameter holes in the second row are designated to be drilled from (R ₆ , L ₂ ) to (R ₁₁ , L ₂ ). FIG.
In 0 (A), bits 6 to 11 are "ON"
And the rest are "OFF". As a result, only the punches in the sixth to eleventh rows are valid.

The large diameter holes in the third row are designated to be drilled from (R ₃ , L ₃ ) to (R ₈ , L ₃ ). FIG.
In 0 (B), bits 3 to 8 are “ON”. As a result, only the punches from the third row to the eighth row are effective.

FIG. 11 shows punching information output when punching the _four patterns P _{1 to} P ₄ shown in the lower part of FIG. 8B. As shown in FIG. 11, in the pattern P ₁ , both the large diameter hole and the small diameter hole are “ON”. In the pattern P ₄ , both lines are “OFF”. In the pattern of P ₃ , only the small diameter hole is effective, and r ₇ to r _{10 in the} 1st row are “ON” and the R row is “OFF”. In the pattern of P ₄ , only the large diameter hole is effective, and only R _{11 to} R ₁₃ of the R row are “O”.
N ”and l lines are“ OFF ”.

The drilling information is not limited to the two types of holes having large diameters and small diameters, and holes having different diameters may be prepared. For example, if 3 types of holes are provided, 2 ³ = 8 types of patterns can be created. Further, by enabling every other punch, providing punches having different opening diameters in the same punch row, and the like, it is possible to generate abundant patterns regardless of the kinds of holes.

In addition, the punching information for two rows is read out simultaneously to the punch rows that carry holes having different opening diameters, and one row, three rows, and four rows are also read.
The punching information may be simultaneously supplied according to the number of rows that the punch device can handle, such as the number of rows and the number of rows greater than that. As shown in FIG. 1, all punching information may be supplied to all punch driving means (electromagnetic valves, etc.) as long as the punching device is capable of punching the entire surface of the die at one time. In addition to shifting the pitch for punching holes having different opening diameters as described above, it is also possible to change the parameters and patterns so that holes of punch rows having different opening diameters are provided in the same row.

Iv) Panel feeding process The panel feeding device 300 starts the panel feeding process in response to the feed signal supplied from the reciprocating motion control circuit 70 of the punch device 200.

FIG. 12 shows a flowchart of the panel feeding process. FIG. 13A shows the target function when the triangular drive is performed, and the step shape of the broken line is the actual output frequency. FIG. 13B shows an actual output pulse of each part. Similarly, FIG. 14 shows the target function and the output frequency when the trapezoidal drive is performed, and FIG. 14B shows the state of the actual output pulse of each part.

The function generating circuit 82 operates by loading a program for panel feed control into a general microcomputer. In step S50, the user uses the keyboard 81 and the like while looking at the monitor 80 to set the control characteristics of the motor as function information. The control characteristic is that the motor to be driven is driven in a triangular shape (see FIG. 13A).
It is known that the driving method (see FIG. 14) or the trapezoidal driving method (see FIG. 14A) can obtain a preferable result when the inertia of the apparatus is also taken into consideration. The setting contents include a fixed period (for example,
The function generating circuit 8 uses the frequency value in each cycle of the “triangle” or the “trapezoid” that changes every 1 [ms]) as a function table.
Store in 2. Alternatively, the user can specify the rising or falling characteristics of the'triangle 'or'trapezoid', the characteristics of the short side of the'trapezoid 'as a simple linear function, or the'triangle'or'trapezoid'. A method of designating the vertex portion as simple coordinates with the starting point as the origin may be considered. The function generating circuit 82 may generate necessary output frequency information as a code in advance based on these linear functions or coordinates, store it in a predetermined function table, and use it. The user specifies the control characteristics suitable for the number of pitches to be conveyed, the panel mass, etc. in the function generating circuit 82.

When the panel operation is started in step 51, the function generating circuit 82 waits for a sending signal to be input as an interrupt signal (step S52). When one punching operation of the punching device 200 is completed and a feed signal is supplied (step S52: YES), the function generating circuit 82
Outputs the initial value as a code. For example, in FIG.
When the triangular drive of (A) is selected, the first code "1" is output. The code is directly connected to the frequency information, and the programmable oscillator 83 oscillates a control signal pulse of frequency 1 [kHz] corresponding to the code. At the same time, the programmable oscillator 83 operates a timer based on an internal clock. The motor driver 84 power-amplifies the oscillated control signal to generate a motor 8 which is a stepping motor.
5 starts rotating at the number of rotations corresponding to the frequency, and the conveyance of the panel P starts.

The programmable oscillator 83 outputs an interrupt signal to the function generating circuit 82 when a predetermined time (for example, 1 [ms]) elapses by a timer. Function generation circuit 8
When the output timing is reached by the interrupt signal of 2 (step S54: YES), the next data is read from the function table or directly calculated by the function information, and the next code "2" is output (step S56). ). The programmable oscillator 83 generates a control signal having a corresponding frequency of 2 [kHz], and the motor 85 is rotated at a higher rotation speed via the motor driver 84.

When the function value to be output next time is not zero in step S57 (step S57: YES)
Repeats the function output (steps S54 to S56). By this repetitive operation, FIG. 13A or FIG.
The motor is driven close to the target characteristics as indicated by the solid line. When the function value becomes zero (step S57: N
O), and one panel conveyance is completed.

In step S58, it is inspected whether all punching operations have been completed. When the punching operation is continued (step S58: NO), it waits for a new feed signal to be supplied from the punching device 200 (step S52), and steps S53 to S57 are repeated. If the punching operation is to be ended (step S58: YES), the panel feeding step is ended. Characteristics of First Example As described above, various characteristics according to this example are shown.

FIGS. 15 and 16 exemplify panels produced by the panel punching device of this embodiment. FIG. 15A shows a panel in which image data of a “person's face” is captured by a scanner and quantized into four values. FIG. 15B shows a panel in which the image data of the “person's face” is captured and then negative / positive is inverted by the image generation circuit 5.

As can be seen from FIG. 15, even complicated patterns / designs and photographic information which could not be created conventionally can be easily panelized. Figure 16 shows that after capturing the design of "Ginkgo leaf" with a scanner, it is divided into 5 in "Division mode", and the panel is manufactured separately based on each divided image data, It is a connection.

Ii) Drilling information generating apparatus According to the drilling information generating apparatus of the present embodiment, arbitrary drilling information can be generated in addition to the data input with the normal image processing. Not only photos and designs, but also word information can be easily reflected in the punching information using a word processor. Even if the size of the original image and the panel to be printed do not match, enlargement, reduction, etc. can be performed.

Further, the user can freely set the control characteristics, and the degree of freedom of control is very high. (II) Second Embodiment The second embodiment relates to a panel punching device to which the invention described in claims 12 to 14 is applied. Configuration of Second Embodiment i) System Configuration FIG. 18 shows an overall configuration diagram of the panel punching device of the second embodiment.

A drilling information generating device 100 ',
N for making a hole in the panel P based on the numerical control information
C machine tool 400.

Ii) Drilling information generating device The drilling information generating device 100 'of this embodiment is the same as the drilling information generating device 100 of the first embodiment.
It is composed by adding.

Similar to the first embodiment, the scanner 24, the keyboard 25, and the mouse 26 input image information and operation commands, and the disk 27 and hard disk 28 store and read various information. The monitor 29 displays image information.

The microcomputer 10 'is composed of an image generation circuit 20, a memory 21, an array allocation circuit 22 and a command data conversion circuit 23. The image generation circuit 20,
The memory 21 and the array allocation circuit 22 operate in the same manner as in the first embodiment, and output punching information. That is, the image generation circuit 20 multi-values the input image data while using the memory 21, based on the brightness, hue, saturation, and the like. The array allocation circuit 22 allocates an array pattern of holes, which is a combination of large and small holes, to each of a plurality of regions divided by multi-value quantization.

Further, in the present embodiment, the hole pitch is not fixed to the die of the punch device, and the hole position can be controlled in millimeter units. Therefore, the array allocation circuit 22
Alternatively, the punching information may be created by performing image processing such as contour line extraction of image data and arranging holes along the extracted contour lines.

The command data conversion circuit 23 corresponds to the information conversion means in claim 13. The command data conversion circuit 23 converts the perforation information including the position of the hole to be formed in the panel P and the size of the opening to N.
C Converts to command data used to control machine tools.

Although each circuit described above acts as an independent functional block when the microcomputer 10 'operates according to a program, each circuit may be configured by hardware.

Iii) NC machine tool The NC machine tool is a general term for a machining machine capable of precise and flexible control by controlling using numerical data. In this embodiment, of the NC machine tools, a so-called turret punch device is used, in which punches having a plurality of opening diameters are mounted on a rotary table and punching operations can be performed while switching a plurality of types of punches according to command data. Examples of the turret punch device having such characteristics include "COMA" series and "PEGA" series manufactured by Amada.

However, the NC machine tool is not limited to the turret punch device, and another device may be used as long as it is an NC machine tool capable of punching operation by NC control. The NC machine tool 400 of this embodiment is
By inputting the command data, it is possible to make an arbitrary hole in the mounted panel P.

The NC control circuit 90 analyzes the inputted numerical control information, that is, command data, and drives various driving means by the operation amount corresponding to this. The punch selection gear 92 is
The turret 93 is rotated by a designated amount according to a command from the NC control device. Then, the target punch is selected together with the selection operation of the striker 94 in the radial direction of the turret 93.

The turret 93 has a plurality of punches continuously arranged on one or a plurality of concentric circles on the turret. Then, one concentric circle is selected by the operation of the striker 94 in the radial direction of the turret, and one punch is selected from the punches mounted on the concentric circle selected by the rotation of the punch selection gear 92.

The striker 94 performs a punch selecting operation in the radial direction of the turret 93 in response to a command from the NC control circuit 90, and further strikes out a selected punch in a direction perpendicular to the turret disk according to a strike command, and the panel P
Punch out.

The carriage base 95 is equipped with a stepping motor and transfers the panel P gripped by an amount designated by the NC control means in the X-axis direction. The side table 96 is also equipped with a stepping motor, and transfers the panel P in the Y-axis direction by an amount designated by the NC control means.

The NC machine tool 400 has a drilling information generating device 100 'and a communication line (for example, RS-232C).
In addition to the above connection, the information once stored on the disk or tape may be read and operated by the loader 91 that reads information from the disk or paper tape. Description of Operation Next, the operation will be described.

Since the punching information which is the basis of the punching operation by the NC machine tool 400 is generated by the same punching information generating step as that of the first embodiment, detailed description thereof will be omitted.
Now, the image generation circuit 20 and the array allocation circuit 22 generate the punching information as shown in FIG. 8B from the original image shown in FIG. 8A by the same operation as that of the first embodiment. And

The user sets the window W on the screen displayed on the monitor 29 as in the first embodiment. The array allocation circuit 22 transfers the punching information regarding the set window W to the command data conversion circuit 23.

Normally, the NC machine tool sets one of the corners of the panel P to be machined as the origin, and adjusts the punch position based on the absolute coordinates or relative coordinates from the origin.

The command data conversion circuit 23 converts the work content for each hole into command data for the NC machine tool based on the supplied drilling information regarding the window W. The command data can be appropriately changed according to the specifications of the NC machine tool. For example, it is possible to use programming languages such as EIA code and JIS code as the generally used command data.

In the programming language, coordinates, tools to be used, etc. can be set for each machining. For example, characters such as "X" are used to set the X coordinate, "Y" to set the Y coordinate, and "T" to specify the tool. For example, 300 mm from the origin of the panel in the X-axis direction and 200 in the Y-axis direction.
[Mm], when using the punch of tool number 201, it can be expressed as G90 X300 Y200 T201. G90 is the command data of the work content to perform the punching operation with the absolute coordinates from the origin.

The command data conversion circuit 23 recognizes the relative coordinates of the corner of the window W designated in the coordinates on the panel P, and then individually recognizes the position information of the hole included in the drilling information and the relative coordinates of the window. Recognize the coordinates of the hole in. Further, the number of the tool (punch) to be used is specified from the information on the type of hole (size of the opening) included in the drilling information. Then, a programming language is generated as a character code from the drilling information for each hole, and the programming language for all the generated holes is set as N control information.
Output to C machine tool 400.

FIG. 19 shows an explanation of drilling in the NC machine tool. When punching the design of "Seagull" shown in FIG. 8B, a large diameter hole and a small diameter hole are required. For example,
When the punch tool number for punching a large diameter hole is 210 and the tool number for punching a small diameter hole is 309, the programming language for punching a small diameter hole H ₁ in FIG. 9 is G90 X60 Y60 T309. In the following, when the machining is performed in the order of H ₂ , H ₃ , H ₁₁ , H ₁₂ , H ₁₃ , and H ₁₄ , the programming language is as follows.

[Example of Position Control Information] G91 X60 T309 (Regarding H ₂ ) X60 (Regarding H ₃ ) G90 X90 Y120 (Regarding H ₁₁ ) G91 X60 T210 (Regarding H ₁₂ ) X60 (Regarding H ₁₃ ) X60 (H ₁₄ ) Regarding Note) In the above list, G91 is command data for designating movement by relative coordinates.

The command data conversion circuit 23 collectively transfers the created numerical control information for each hole, each column, or all the holes of the window W via the communication line of the NC machine tool.
When the panel production site is far away, the numerical control information is temporarily stored in the disk, and the loader 91 is used at the production site.
It may be configured to transfer to the C machine tool 400.

The NC control circuit 90 analyzes the transferred numerical control information and processes the specified contents for each hole. That is, in the numerical control information, the stepping motor in the carriage base 95 is driven by the distance designated by the "X" code, and the stepping motor in the side table 96 is driven by the distance designated by the "Y" code. When the tool number "T" is designated, the punch selection gear 92 is driven to rotate the turret 93, and the striker 94 is driven in the radial direction of the turret 93 to select the corresponding punch. Then, the panel P is punched out by this punch.

In this way, holes corresponding to the drilling information are generated at arbitrary positions on the panel P. Some NC machine tools can form continuous holes in the diagonal direction of the coordinate system or can form holes on a predetermined arc. When using such an NC machine tool, the array allocation circuit 22 generates drilling information including a row of these holes, and the command data conversion circuit 23 uses "I", "J", "K", etc. as a programming language. If you specify the code of, you can punch diagonally and punch in an arc. Effects of Second Embodiment As described above, according to the second embodiment, the command data conversion circuit 23 sequentially translates the punching information into the programming language for NC, so that, for example, on the panel P, ,
It is possible to reflect the design of the'seagull 'as in this embodiment.

In particular, if the turret punching device is used, not only large-diameter holes and small-diameter holes can be punched, but a large number of types of openings can be punched, so that holes having different openings can be arranged in a row. If the NC machine tool is compatible, holes can be provided diagonally and a row of holes can be provided on an arc.

[0129]

According to the invention described in claims 1 and 4, since the perforation information is generated from an arbitrary pattern and each hole is provided in the panel in association with each other, it is possible to capture and create as image data. All possible data, such as line drawings, photographs, characters, video images, etc., can be panelized.

According to the second and fifth aspects of the invention, since the holes are punched for each row, it is possible to reflect an arbitrary design on a large panel. This is a preferable method for a punching device.

According to the third and sixth aspects of the present invention, since an arbitrary array of holes is generated and a pattern is assigned according to the luminance information or color information of the original image, an arbitrary pattern is assigned to each area. It can be distributed to create panels.

According to the invention described in claim 7, since the punch can be individually controlled by the punch driving means,
By supplying the punching information that changes arbitrarily to each punch driving means, a panel having an arbitrary design can be created.

According to the invention described in claims 8 and 9, the control motor can be easily controlled by further converting the code obtained by the user setting the function condition into the frequency. Therefore, it is possible to economically provide the panel feeding device using a personal computer or the like. Further, since the user can freely set / change the function condition, the degree of freedom of control is high.

According to the tenth aspect of the invention, the punching operation of the punching device and the punching driving operation based on the punching information can be alternately repeated without conflict, so that a suitable panel punching device can be provided.

According to the eleventh aspect of the present invention, the punching operation of the punching device, the punching driving operation based on the punching information, and the panel feeding operation are performed in synchronization with each other. An opening device can be provided.

According to the twelfth to fourteenth aspects of the invention, since the numerically controlled machine tool faithfully makes a hole based on the hole making information made from the original image, a panel having an arbitrary pattern is made. it can. In particular, according to the present invention, it is possible to easily perform automatic programming for creating a design even for a conventional numerically controlled machine device in which it is difficult to create a complicated design and the programming language itself is also difficult. . Therefore, even if the user has little knowledge about numerical control, it is possible to create a complicated design on the panel by using the numerical control machine tool.
