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 technique for punching a panel to reflect a design on a panel.

[0002] Generally, a panel is a kind of building material.
Used for balconies, fences, etc. When a panel is used as a building material, consideration for decorativeness is more important than other building materials because the surface area is large and the possibility of being exposed to human eyes is high. In particular, with the enhancement of social capital in recent years, aesthetics have been required for buildings used in the private sector. Due to such social demands, higher decorativeness is required for panels. Therefore, a technique for freely forming a pattern on a panel is required.

[0003]

2. Description of the Related Art Heretofore, in order to enhance the decorativeness of a panel, a regular hole array has been provided on the surface of the panel by a panel punching device.

FIG. 20 shows how the conventional panel is manufactured. Panel P ₀ consists of a flat plate of iron or the like having a predetermined thickness. Mold 101 plays an important role to determine the pattern provided to the panel P _0. A plurality of punches 102 are provided on a punching surface of the mold 101. Punching operation for the panel P ₀ is the mold 101 in which a plurality of punches 102 regularly carried out by pressing with a predetermined pressure. When the width of the panel P ₀ is wider than the mold 101, the operation of feeding the panel P ₀ by a predetermined amount for each pressing operation is repeated, and holes are provided in the entire panel P ₀ .

[0005] panel feeder 105 outputs a control signal for sending the panel P _0. This control signal is, for example, frequency information, and is converted into a rotation speed by the motor 104. The motor 104 is directly connected to the roller 103,
A torque is generated by the control signal, and the panel 100 is transported by a fixed amount. In many cases, the panel feeding operation also serves as a panel material rolling operation.

[0006]

However, the above-mentioned conventional panel punching apparatus cannot form various patterns on the panel. Further, the conventional panel feeder has problems that the motor control device is very expensive and the user cannot freely control the characteristics.

[0007] The above-mentioned problem will be specifically described. First, in a panel punching device, a pattern that can be provided on a panel is defined by a mold. Therefore, in order to form a plurality of different patterns, it is necessary to provide a mold for each pattern. But,
In general, dies are very expensive, so that dies are usually produced only for mass production, and dies are not produced for one-off products. Also,
Even if a plurality of dies are manufactured, the apparatus must be stopped once to replace the dies, and changing the dies requires labor and time. Therefore, only one type of mold was actually manufactured. In this case, only a panel of a type that can be mass-produced can be manufactured, and the conventional panel punching apparatus is not suitable for manufacturing small-quantity, multi-product panels.

Further, according to the conventional panel punching device,
Even if the pattern of holes is devised within the range of the punching area of the mold, the panel is usually manufactured by alternately repeating the feeding operation and the punching operation. It was merely a repetition of the arrangement of holes according to the design described above, and it was undeniable that the overall pattern became a monotonous panel.

On the other hand, in the conventional panel feeder, since the panel feed operation is controlled with optimal transport characteristics for all materials, the panel feeder has abundant functions but is very expensive as a whole. Had become. Further, even if a user attempts to set the optimum servo characteristics of the machine tool and tries to set an optimum one, fine optimization cannot be performed because the function is limited to several types of function characteristics stored in the apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the method and apparatus for punching a panel, a punching apparatus, and a method and apparatus for controlling panel feed according to the present invention will be described with reference to the drawings. (I) First Embodiment The first embodiment 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 . 4 , the entire system includes 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 transporting a panel. The following describes each device.

The panel is not limited to a metal panel, but may be changed to a synthetic resin, glass, plastic, rubber or the like. ii) Drilling Information Generating Device As shown in FIG. 4 , the drilling information generating device 100 is mainly configured by a microcomputer 10. The microcomputer 10 includes an image generation circuit 20 that takes in an image from an external device and processes the image, a memory 21 that is a temporary image storage area, and array information of holes for actually punching the generated image data. And an array assignment circuit 22 for conversion. The scanner 24 reads a design from an arbitrary sheet and sets it as image data.

The microcomputer 10 performs an image generating operation and an array allocating operation described below by a program, but these may be constituted by hardware. The keyboard 25 transmits a user 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 for creating an image. The disk 27 is a storage medium for storing images and punching information at another location and for reading data created at another location by a microcomputer connected to the punching device. The hard disk 28 stores a large amount of image data in addition to storing programs. The monitor 29 displays image information. The adapter board 30 includes a large-diameter hole port 31 that performs switching of a large-opening hole (hereinafter, referred to as a large-diameter hole) and a small-diameter hole port 32 that performs switching of a small-opening 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 may be provided at an input stage of the main body of the punching device 200. Each port is provided with a required number of punch terminals (for example, 100 terminals).

The microcomputer 10 includes the punch device 2
The position information supplied by the reciprocating operation control circuit 70 is input to an external interrupt terminal. The following modifications are possible for the perforation information generation device.

As an image input means, a camera can be input. In other words, if a video camera is used as an input source and input to the image generation circuit via a video signal-pixel signal converter, a normal image such as a landscape or a person can be taken as a still image on a panel as long as it can be taken by the camera. Can be reflected.

Instead of arranging fixed patterns in each area, the arrangement allocating circuit may automatically generate an arbitrary pattern having an appropriate aperture area ratio according to the magnitude of luminance information or color information. . This eliminates the necessity of the operation of allocating the array, and facilitates the panelization of the multi-valued image.

Iii) Punching Apparatus The punching apparatus 200 has a reciprocating operation control system for controlling the entire reciprocating operation of the punch, and a pneumatic control system for controlling the validity / invalidity of the punch.

The reciprocating operation control system includes a reciprocating operation control circuit 70 for controlling the reciprocating operation, and a wire 72 having a weight 71.
And a flywheel and a motor 74 for reciprocating a punch row including a die.

The air pressure control system includes a compressor 40 including a tank for generating compressed air and a valve 41.
A regulator 42 for adjusting the air pressure to a constant pressure;
The air output from the regulator 42 is supplied to a large-diameter hole punch row L for performing a large-diameter hole punching operation and a small-diameter hole punch row l for performing a small-diameter hole punching operation.

The large-diameter hole punch row L and the small-diameter hole punch row 1 have the same configuration except for the difference in the hole diameter of the punch, and are suspended by the wire 72 and reciprocate as a whole. Each row supplies compressed air from the regulator 42 to two pipes in accordance with a switch signal supplied from a large-diameter hole port 31 (small-diameter hole port 32; hereinafter, the notation in parentheses indicates a symbol related to the small-diameter hole port 1). Solenoid valves 50, 51 (60, 61) for selecting and supplying one pipe from among them, and cylinders 52, 53 (62, 63) to be pushed or retracted by the flow of air selected by each solenoid valve. And the cams 54 and 55 (6
4, 65). The mold 58 is in an extruded state (ie, an effective state) or a retracted state (ie, in a retracted state) according to the movement of each cam.
The punches 56, 57 (66, 67) in the invalid state are held so as to be able to reciprocate.

FIG. 5 shows the mechanism of the punch portion actually installed in the mold. The reference numerals in FIG. 5 correspond to the reference numerals of both punch rows in FIG. As shown in FIG. 5, both punch rows are provided so as to face each other, and a die 58 includes a punch 56 for a large-diameter hole and a punch 66 for a small-diameter hole. In the figure, an ON (“ON”) signal is supplied to the solenoid valve 50 from the large-diameter hole port 31. Regulator 42
Is supplied to the rear port of the cylinder 52, and the cam 54 is pushed out. Since the cam has a shape as shown in FIG. 5, the punch 56 is in an extruded state. On the contrary,
The solenoid valve 60 is turned off from the small-diameter hole port 32 (“OF
F ") signal is provided. Therefore, the air is
The cam is supplied to the air on the front side of 2 and the cam is in the retracted state, and the punch 66 is also in the retracted state. When the punch is pressed, if the length of each punch is adjusted so as to punch the panel P only when the punch is in the extruded state, it is possible to control whether or not to punch the hole only by controlling the switch signal. The control mechanism of these punches is a known technique.

The number of punch rows is not limited to two, but may be one row, three rows, four rows, or more rows depending on the amount of punch information that can be simultaneously supplied by the punch information generating means. A number may be provided. By adjusting the pitch of the mold 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 mold to reflect all the punching information at a time.

The switch is not limited to the control by the solenoid valve, but any other valve means, for example, an electric switch, may be used as long as it can control the pushing and pulling of the cylinder. As the medium, water pressure and hydraulic pressure can be used in addition to air pressure. That is, any information that can reflect the electrical switch information as the validity / invalidity of drilling may be used.

The punching device is not limited to a punch, but may be any device capable of punching a panel, such as drilling, electric discharge machining, laser beam machining, and electrolytic machining. When using these processing tools, instead of providing drilling means in a horizontal row, the table on which the panel is mounted is structured to be movable in the X direction or Y direction along with the scanning of the drilling information. It is preferable to make holes one by one with the scanning.

Iv) Panel feeder The panel feeder 300 finally feeds the panel P by rotating the roller 86.

A general microcomputer can be used as the function generation circuit 82. The user performs setting / change of a function from the keyboard 81 while watching the monitor 80. The programmable oscillator 83 outputs a control signal having a frequency corresponding to the code output from the function generation computer 82,
Function generation computer 8 interrupts at predetermined timing
Multiply by 2. The programmable oscillator 83 is set in an expansion slot or the like of the computer. Motor driver 84
Amplifies the power of the control signal so that the motor can be driven,
The motor 85 is rotated.

As the programmable oscillator 83, one that directly opens and closes an analog switch by a code to change the time constant of the oscillator, and one that once D / A converts a code and
A device that drives an O circuit is conceivable.

In addition to the stepping motor, any other motor can be used as long as it has excellent response characteristics, large output, high rotation, maintainability, long life, etc. as a driving servomotor. For example, using a DC control motor, 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 generation 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. Description of Operation Next, the operation of the embodiment will be described. A description will be given in order from the punching information generation step to the punching step, and a detailed operation related to the panel feed step will be described later. A case in which a flying "gull" pattern is formed on a panel will be described as an example.

FIG. 6 is a flowchart conceptually showing the operation of the entire system, and FIG. 7 is a flowchart of a program actually operating in the microcomputer 10. i) Drilling Information Generation Step When starting the operation, a drilling information generation step according to steps S1 to S3 in FIG. 6 is performed.

Hereinafter, description will be made with reference to the flowchart of FIG. The microcomputer 10 includes the hard disk 2
By starting the drilling information generating program stored in the storage device 8 or the like, the drilling information generating device 100 starts to operate. 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 “gull” on the scanner 24 and selects “I / O” on the menu screen to designate a scanner input (step S30: YES), the image generation circuit 20 reads an image from the scanner 24 (step S30: YES). Step S31).

If the scanner 24 generates pixel information in accordance with the luminance, the pattern of "Kamome" shown on the paper is read after being binarized or further multi-valued according to the luminance distribution. Stored in the memory 21. Scanner 24
Is stored in the memory 21 including the color information according to the color distribution of the design. This work is
It works in the same way that the area conversion circuit 22 works. If the design is read in multiple gradations (for example, 16 gradations, 256 gradations, etc.), the gradation is reduced by an image processing program (for example, 2 gradations, 4 gradations, etc.). Processing may be performed.

If the read image data is to be processed (step S33: YES), the user selects "correction" from the menu. Image processing uses known image processing to enlarge, reduce, rotate, flip, move,
Copying can be performed arbitrarily, and a mouse 26, a keyboard 25
You can also draw using. Here, the user
Design bar below into four colors of the "gull" (area A ₁ to A ₄₎
Shall be drawn.

It is assumed that an image as shown in FIG. 8A is read and processed as a result of the above operation. Here, design is made an area A ₁ to A ₄ having four gray are four values. Furthermore, when entering characters (step S3
2: YES) “OP” (optional) is selected, and the user can input characters from the keyboard 25.

Next, a pattern of an arrangement 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 using 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 (step S38). In this embodiment, since two types of large-diameter holes having a large opening and small-diameter holes having a small opening are used, at least 2 ² = 4 types of patterns in a simple arrangement can be obtained. The pattern is further increased by making the hole arrangement periodic. Here, the user assigns the four patterns according to the existing four patterns.

FIG. 8B shows this operation.
The display of the perforated hole information is shown in place of the original image of FIG. In the display example shown in FIG. 8 (B), 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 a low luminance, and a pattern having a small opening area is arranged in a portion having a high luminance. As a result, FIG.
Four patterns as shown in _{(B) (D 1 ~D 4} ) is arranged.

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

When ending the processing (step S41: Y
ES) ends the program. If the process is not to be terminated (step S41: NO), the process waits for menu input. When performing a punching operation, "I / O" is selected from the menu and a port output is designated.

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

In the captured image data, the aspect ratio of all data does not always match the aspect ratio of the panel. for that reason,
The image is divided in the division mode, and perforation information is printed on the panel for each divided unit, or a window is set inside the image data and only the range of the window W is printed on the panel. Here, a window is used. Step S6
Then, the window W is used to specify the range in which the punching information is actually read. In FIG. 8B, a window W is set for the hole information display of the design of “Kamome”.

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 Example of input numerical value X-direction punch number 200 Y-direction punch number 200 X-direction punch pitch [mm] 5.000 Y-direction punch pitch [mm] 5.000 X-direction division number 3 Y-direction division number 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 The direction in which the panel material is inserted is defined as the X direction, and the extending direction of the row of punches perpendicular to the X direction 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 the number of divisions of the entire design, and 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 method of dividing, and the punch mode is a selection field of a registered pattern to be reflected in each area. These parameters can be appropriately selected by selecting “mode” from the menu of the drilling information generation program of the microcomputer 10. With the above settings,
The holes to be used and the arrangement state can be set. In this embodiment, the pitch between the large-diameter holes is equal to the pitch between the small-diameter holes. The row of large diameter holes and the row of small diameter holes are shifted 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 starts the system operation by turning on the power of the entire system.

At step S9, the microcomputer 1
0 waits for a feed signal to be input from the punching device 200 as an interrupt signal. When reciprocating the entire punch row, the punch device 200 can provide information according to the posture. For example, an angle state in each operation can be encoded and output, with the state where the panel row rises most at 0 ° and the state where the panel row falls most at 180 °. Any angle condition where the punch is completely pulled out of the panel and is stable (for example, 240 °)
It is also possible to set so as to output a predetermined pulse signal. Here, we choose the latter method. The pulse signal is sent to the perforation information generating device 100 and the panel feed device 300, and is used as a punch control timing signal (hereinafter, referred to as a feed signal).

If there is an interruption due to the feed signal (step S9: YES), punch control is performed. At the same time, in a panel feeding process of the panel feeding device 300 described later, the panel P is moved by a predetermined amount (a distance of 1/2 of the punch pitch)
Only in the X direction.

FIG. 9 shows the window W range in FIG.
It is shown enlarged. In the window W of FIG. 9, the coordinates of the large-diameter hole
To uppercase (R_n, L_m), Small hole coordinates
(R_n, L _m). n and m are the origin at the upper left of the drawing
(R₁, L₁), (R₁, L₁)

A row of punches for holes is opposed at a fixed distance d. Figure
When the panel is conveyed in the direction indicated by the large arrow in FIG.
The row of punches is punched first. The actual pitch d on the mold is
The display in FIG. 9 corresponds to the pitch D. In FIG.
Is set to be sent from bottom to top
Therefore, the drilling information generation device 1 is configured to
A row ahead of the information sent to the bore port 31 by the relative distance D
It is necessary to supply the information of.

The drilling information generating device 1 converts the information in the window W into serial information line by line,
Supply 0. Each port in the adapter board 30 latches this serial information and outputs it as parallel switch information. This may combine a shift register and a buffer. In addition, a PIO (Parallel I / O LSI) for microcomputer is used for each port, and I / O
It may be 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.

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 ,
l ₆₎ until the data is 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
If the data of the entire line has 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 one-line information of the large-diameter hole is loaded (step S15). Since the punch and the large-diameter hole distance D delay with respect to the small-diameter hole as is done in the example of FIG. 9 in the second row (R _1, L ₂₎ from (R _14, L ₂₎
Are sent to the large diameter port 31. When the one-line information of the large-diameter hole is reflected in the port similarly to the one-line information of the small-diameter hole (step S18), all the terminals are loaded (step S20), and the output information is transmitted to each solenoid valve of the punching device 200. Sent to Each solenoid valve performs a cam push-out operation and a pull-in operation in accordance with the ON / OFF information of the corresponding terminal, and new punching information is reflected in the punch-out pull-in operation of the punch. The punching device 200 performs punching under the control of the reciprocating operation control circuit 70, and holes corresponding to the small-diameter hole information in the sixth row and the large-diameter hole information in the second row are simultaneously provided in the panel P.

When the drilling operation is completed, the flywheel of the control circuit
When 73 returns to the position of 240 °, the reciprocating operation control circuit 7
A value of 0 indicates that the sending signal is valid (for example, L level). Drilling
The information generation device 100 receives this by interruption, and
The steps from step S9 are repeated. The next action is:
The small-diameter hole column (r₁, L₇) To (r₁₃,
l ₇), The third row of large-diameter hole columns (R₁, L
_Three) To (R₁₄, L_Three) Is loaded and the
The operation from step 10 to step 21 is repeated
You.

When the fifteenth line of the large-diameter hole ends (step S21: YES), the punching operation ends. iii) Description of drilling information FIG. 10A shows drilling information of the small-diameter hole in the sixth row and the large-diameter hole in the second row described above. FIG.
(B) shows drilling information of the small-diameter hole in the seventh row and the large-diameter hole in the third row that are loaded in the next punch. In each case, the upper row is the drilling information loaded into the large-diameter hole port 31, and the lower row is the drilling information loaded into the small-diameter hole port 32. The number is the bit (terminal) number, that is, the order of punching.

In FIG. 9, small holes are arranged over the entire surface of the window W. Accordingly, the dot information in the small-diameter hole columns l ₆ and l _{7 in} the _sixth and _seventh 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 is “OFF”. Thus, only the punches in the sixth to eleventh rows are valid.

In the large-diameter holes in the third row, holes from (R ₃ , L ₃ ) to (R ₈ , L ₃ ) are designated to be drilled. FIG.
At 0 (B), bits 3 to 8 are "ON". As a result, only the punches in the third to eighth rows are valid.

FIG. 11 shows drilling 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, both the large-diameter hole and the small-diameter hole is "ON" in the pattern P _1. In the pattern of P ₄ both of the line is "OFF". Only the small-diameter hole is effective in pattern P _3, until r ₇ ~r ₁₀ l of rows is "ON", R rows "OFF". The pattern of P ₄ is effective only large-diameter hole, only the R ₁₁ to R ₁₃ of R rows "O
N ”and l rows are“ OFF ”.

Note that the drilling information is not limited to the two types of large-diameter hole and small-diameter hole, and holes having different diameters may be prepared. For example, if three types of holes are provided, it is possible to create as many as 2 ³ = 8 types of patterns. Further, by making punches effective every other punch, providing punches having different opening diameters in the same punch row, and the like, the types of holes are not limited, and a richer pattern can be generated.

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

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

FIG. 12 shows a flowchart of the panel feeding step. FIG. 13A shows a target function when the triangular drive is performed, and the step shape indicated by the broken line is the actual output frequency. FIG. 13B shows the actual state of the output pulse from each unit. Similarly, FIG. 14 shows a target function and an output frequency when performing trapezoidal driving, and FIG. 14B shows actual states of output pulses of each unit.

The function generating circuit 82 operates by loading a program for controlling panel feed into a general microcomputer. In step S50, the user sets the motor control characteristics as function information using the keyboard 81 or the like while watching the monitor 80. As the control characteristics, the motor to be driven is driven in a triangular shape (FIG. 13A).
It is known that a device which drives by a trapezoidal drive (see FIG. 14A) or a trapezoidal drive obtains a preferable result in consideration of the inertia of the device. The setting content is a fixed period (for example,
1 [ms]), a frequency value in each cycle of a “triangle” or a “trapezoid” that changes every one [ms] is used as a function table, and the function generation circuit 8
Store it in 2. Other methods include the user specifying the rising or falling characteristics of the 'triangle' or 'trapezoid', the characteristics of the short side of the 'trapezoid' as a simple linear function, the 'triangle' or 'trapezoid' A method of designating the vertex 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, and store the code in a predetermined function table for use. The user specifies control characteristics suitable for the number of pitches to be conveyed, panel mass, and the like to the function generation circuit 82.

When the panel operation starts in step 51, the function generating circuit 82 waits for the input of a sending signal 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, FIG.
When the triangular drive of (A) is selected, the first code “1” is output. The code is directly connected to the frequency information as it is, and the programmable oscillator 83 oscillates a control signal pulse having a frequency of 1 [kHz] corresponding to the code. At the same time, the programmable oscillator 83 operates a timer based on the internal clock. The motor driver 84 power-amplifies the oscillated control signal, and outputs the motor 8 as a stepping motor.
5 starts rotating at the number of rotations corresponding to the frequency, and the transport of the panel P starts.

The programmable oscillator 83 outputs an interrupt signal to the function generation circuit 82 when a predetermined time (for example, 1 [ms]) has elapsed by the timer. Function generation circuit 8
When the output timing comes due to the interrupt signal No. 2 (step S54: YES), the next code "2" is output by reading the next data from the function table or directly calculating the function information (step S56). ). The programmable oscillator 83 generates a control signal having a corresponding frequency of 2 [kHz], and the motor 85 rotates at a higher rotation speed via the motor driver 84.

In step S57, when the function value to be output next time is not zero (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 characteristic as shown by the solid line. When the function value becomes zero (step S57: N
O), one panel transfer ends.

In step S58, it is checked whether all the punching operations have been completed. If the punching operation is continued (step S58: NO), the process waits for a feed signal to be newly supplied from the punching device 200 (step S52), and repeats steps S53 to S57. If the punching operation is to be ended (step S58: YES), the panel feeding step ends. Characteristics of the First Embodiment As described above, various characteristics according to the present embodiment are shown.

FIGS. 15 and 16 exemplify panels produced by the panel punching apparatus of this embodiment. FIG. 15A is a diagram in which image data of a 'person's face' is captured by a scanner, quaternized, and formed into a panel. FIG. 15B shows a panel obtained by capturing image data of a “person's face” and inverting the image by a negative / positive in the image generation circuit 5.

As can be seen from FIG. 15, even a complicated pattern / design or photo information which could not be created conventionally can be easily made into a panel. FIG. 16 shows a pattern of “Ginkgo leaves” captured by a scanner, divided into five parts in a “division mode”, and separately manufactured panels based on each divided image data, and then combined into one.

Ii) Drilling Information Generating Apparatus According to the drilling information generating apparatus of the present embodiment, arbitrary punching information can be generated by freely adding data obtained by inputting normal image processing. In addition to photos and designs, word information can be easily reflected in the perforation information by a word processor. Even when the size of the original image does not match the size of the panel to be embossed, enlargement and reduction can be performed. The image data created in the past can be read out and combined with new image data to create punching information freely. Since the hole arrangement can be set for each luminance area and each color area,
Hole information can be created with any gradation and arrangement pattern.

Iii) Punching device According to the punching device of this embodiment, an arbitrary hole can be provided in the panel by supplying a different switch state for each punch to a plurality of solenoid valves. The perforation information may be a fixed value that can be changed by switch means or the like. In this case, a simple pattern such as a striped pattern can be drawn on the panel.

Iv) Panel Feeding Device According to the panel feeding device of this embodiment, a normal personal computer can be used, so that the cost is greatly reduced as compared with the conventional control device. In addition, the user can freely set control characteristics, and the degree of control freedom is very high. (II) Second Embodiment The second embodiment relates to a panel punching apparatus to which the inventions of claims 12 to 14 are applied. Configuration i of Second Embodiment i) System Configuration FIG. 18 shows an overall configuration diagram of a panel punching device of a second embodiment.

Drilling information generation device 100 ′
N to perform a punching operation on panel P based on numerical control information
C machine tool 400.

Ii) Drilling information generating device The drilling information generating device 100 'of the present embodiment is equivalent to the command data conversion circuit 23 for the drilling information generating device 100 of the first embodiment.
It is composed by adding

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

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

In this embodiment, the pitch of the holes is not fixed to the die of the punch device, and the position of the holes can be controlled in units of millimeters. Therefore, the array assignment circuit 22
Alternatively, hole processing may be performed by performing image processing such as contour extraction of image data and arranging holes along the extracted contour.

The command data conversion circuit 23 corresponds to the information conversion means in claim 13. The command data conversion circuit 23 converts the hole punching information including the information on the position of the hole to be drilled in the panel P and the size of the opening into N
C Converts to command data used for controlling the machine tool.

Each of the circuits described above functions as an independent function block when the microcomputer 10 'operates according to a program, but each circuit may be constituted by hardware.

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

However, as long as it is an NC machine tool capable of performing a punching operation by NC control, it is not limited to the turret punch device, but may be another device. The NC machine tool 400 according to the present embodiment includes:
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 input numerical control information, that is, the command data, and drives various driving means with the corresponding operation amounts. The punch selection gear 92 is
The turret 93 is rotated by a specified amount according to a command from the NC control device. Then, the target punch is selected together with the selection operation of the turret 93 of the striker 94 in the radial direction.

In the turret 93, a plurality of types of punches are continuously provided 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 selection operation in the radial direction of the turret 93 in accordance with a command from the NC control circuit 90, and further strikes the selected punch in a direction perpendicular to the turret disk in accordance with a strike command.
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 specified by the NC control means.

The NC machine tool 400 has a communication line (for example, RS-232C) with the drilling information generation device 100 '.
Alternatively, the information may be read from a disk or tape and operated by a loader 91 that reads information from a disk or paper tape. Description of Operation Next, the operation will be described.

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

The user sets the window W on the screen displayed on the monitor 29 in the same manner as in the first embodiment. The array assignment circuit 22 transfers the perforated information on the set window W to the command data conversion circuit 23.

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

The command data conversion circuit 23 converts the machining contents of each hole into command data for an NC machine tool based on the supplied drilling information on 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 a programming language such as an EIA code or a JIS code as generally used command data.

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

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

FIG. 19 shows a description of drilling in an NC machine tool. When punching the "gull" design shown in FIG. 8B, a large hole and a small hole are required. For example,
210 the tool number of a punch for striking a large-diameter hole, when the tool number for hitting the small-diameter hole 309, a programming language for hitting the small-diameter hole H ₁ in FIG. 9 is a G90 X60 Y60 T309. Hereinafter, the case of performing the work in the order of _{H 2, H 3, H 11} , H 12, H 13, H 14, programming language, as follows.

[0124] (with respect to H ₂₎ [position control information of the Example] G91 X60 T309 X60 (with respect to H ₃₎ G90 X90 Y120 (with respect to H ₁₁₎ G91 X60 T210 (with respect to H ₁₂₎ X60 (with respect to H ₁₃₎ X60 (H ₁₄ Note that in the above list, G91 is instruction data for designating movement by relative coordinates.

The command data conversion circuit 23 transfers the created numerical control information collectively for each hole, for each column, or for all holes in the window W via the communication line of the NC machine tool.
If the production site of the panel is far away, the numerical control information is temporarily stored on the disk, and the
You may comprise so that it may transfer to C machine tool 400.

The NC control circuit 90 analyzes the numerical control information to be transferred, and processes the contents specified for each hole. That is, of the numerical control information, the stepping motor in the carriage base 95 is driven by the distance specified by the “X” code, and the stepping motor in the side table 96 is driven by the distance specified 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 a corresponding punch. Then, the panel P is punched by the punch.

In this way, holes corresponding to the perforation information are generated at arbitrary positions on panel P. Some NC machine tools can create a continuous hole in a diagonal direction of the coordinate system, or can provide the hole on a predetermined arc. When such an NC machine tool is used, the array assignment 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. With this code, punching in an oblique direction and punching on an arc can be performed. Effects of the Second Embodiment As described above, according to the second embodiment, the command data conversion circuit 23 sequentially translates the perforated information into the programming language for NC, so that, for example, ,
As in the present embodiment, the design of 'gull' can be reflected.

In particular, if a turret punch device is used, not only large-diameter holes and small-diameter holes, but also many types of openings can be punched, so that holes with different openings can be consecutively arranged in a row. Also, if the NC machine tool can cope, holes can be provided diagonally and holes can be provided on an arc.
