  The present invention relates to a program conversion device, a plate material processing system, and a plate material processing method.

  As a plate material processing system for processing a plate material such as a workpiece, a composite processing machine including a plurality of processing machines such as a punch press machine and a laser processing machine is known (for example, see Patent Document 1 below). The punch press machine positions a processing target area of a workpiece with respect to a punch position, and performs drilling or forming. The laser processing machine performs cutting processing of the workpiece by irradiating the workpiece with the laser from the laser head while relatively moving the laser head and the workpiece. Each of the punch press machine and the laser beam machine is numerically controlled based on a machining program. The coordinate system used for numerical control is a unique coordinate system of each processing machine, and the position of the origin may be different among a plurality of processing machines, and the axis direction may be different between a plurality of processing machines. Therefore, it is necessary for the user (operator) to create a machining program in consideration of the difference in the coordinate system of the plurality of processing machines, which places a burden on the user. Therefore, there is a technique for setting the origin position by sharing the origin position of one processing machine and the origin position of another processing machine when the origin of the coordinate system is different but the axial direction is the same for a plurality of processing machines. It has been proposed (see, for example, Patent Document 2 below).

  FIG. 2 is a block diagram illustrating an example of the plate material processing system 1 according to the embodiment. The plate material processing system 1 includes, for example, an automatic programming device 31, a program conversion device 7, a numerical control unit 6, and servo amplifiers 32 to 35. In the plate material processing system 1, the program conversion device 7 converts the processing program according to each processing unit, and the numerical control unit 6 numerically controls each processing unit based on the converted processing program.

  The automatic programming device 31 generates a machining program. The machining program is, for example, NC data (numerical control data), and includes information defining a relative position, a relative speed, and the like between a tool for machining the workpiece W and the workpiece W. For example, the machining program includes information that defines the position in the X direction, the position in the Y direction, the speed in the X direction, and the speed in the Y direction of the laser head 11 (tool) when performing laser machining. Further, the machining program includes information defining the positions of the tool 22 and the tool 23 in the X direction and the position of the workpiece W in the Y direction when punching. The machining program includes information that defines the position of the tool 26 in the X direction and the position of the workpiece W in the Y direction when tapping.

  For example, the automatic programming device 31 represents the positions of the workpiece W in the X direction, the Y direction, and the Z direction with coordinates in a single coordinate system with the workpiece W as a reference. This coordinate system is a coordinate system having a predetermined position on the workpiece W as an origin. For example, the direction parallel to one side of the workpiece W is the X direction, the direction parallel to the other side of the workpiece is the Y direction, This is a coordinate system in which the thickness direction is the Z direction. The origin of this coordinate system is determined according to the position of the corner of the workpiece W, for example. The automatic programming device 31 is communicably connected to the program conversion device 7 by wire or wireless. The automatic programming device 31 supplies the generated machining program to the program conversion device 7.

  Note that the program conversion device 7 may acquire the machining program from the storage medium 37. The storage medium 37 is, for example, a USB memory or a flash memory. The machining program stored in the storage medium 37 is the same as that generated by the automatic programming device 31. This machining program may be automatically generated by the automatic programming device 31, or may be manually generated by a user, for example. In this case, the plate material processing system 1 may not include the automatic programming device 31.

  The program conversion device 7 converts a machining program supplied from an external device (for example, the automatic programming device 31 or the storage medium 37) according to a machining unit in charge of machining. The program conversion device 7 is provided, for example, in an HMI (Human Machine Interface) such as a panel computer. The program conversion device 7 includes an input unit 41, a processing determination unit 42, a coordinate conversion unit 43, a storage unit 44, and an output unit 45.

  The input unit 41 is, for example, a communication port or a USB port, and receives a machining program from the automatic programming device 31 or the storage medium 37. The processing determination unit 42 determines processing to be allocated to each of a plurality of processing units (laser processing unit 2, punch processing unit 3, tap processing unit 4) based on the processing program. The coordinate conversion unit 43 converts the coordinates of the processing target area on the workpiece W into coordinates corresponding to the processing unit that processes the processing target area based on the determination result of the processing determination unit 42.

  The coordinate conversion unit 43 generates a converted machining program. The output unit 45 outputs the converted machining program generated by the coordinate conversion unit 43 to an external device (for example, the numerical control unit 6). The storage unit 44 stores, for example, the machining program received by the input unit 41, information necessary for processing of the program conversion device 7, the converted machining program generated by the coordinate conversion unit 43, and the like.

  Here, the processing of the program conversion device 7 will be described with reference to FIGS. 3 and 4. FIG. 3A is a conceptual diagram of the machining program PR1. In FIG. 3A, reference numeral A1 is a region (processing target region) in which the laser processing unit 2 takes charge of processing in the workpiece W. The processing target area A1 is represented by, for example, the position of the start point P1 and the end point P2 of the cutting line. The position of the start point P1 and the position of the end point P2 are each represented by coordinates in the coordinate system (XW-YW coordinate system) on the workpiece W. Here, the position of the start point P1 is represented by coordinates (XW1, YW1), and the position of the end point P2 is represented by coordinates (XW2, YW2).

  Reference numeral A <b> 2 is a region (processing target region) in which the punch processing unit 3 takes charge of processing in the workpiece W. The processing target area A2 is represented by, for example, a tool number (eg, ID) corresponding to the position and diameter of the center P3. The position of the center P3 is represented by coordinates in the coordinate system (XW-YW coordinate system) on the workpiece W. Here, the position of the center P3 is represented by coordinates (XW3, YW3).

  Reference numeral A <b> 3 is a region (processing target region) in which the tap processing unit 4 is in charge of processing in the workpiece W. The processing target area A3 to be tapped is subjected to processing such as forming a pilot hole in advance. The processing target area A3 is represented by, for example, the position of the center P4, and the tool number (eg, ID) corresponding to the diameter and pitch. The position of the center P4 is represented by coordinates in a coordinate system (XW-YW coordinate system) on the workpiece W. Here, the position of the center P4 is represented by coordinates (XW4, YW4).

  FIG. 3B is a conceptual diagram showing processing for the processing target area A <b> 1 of the laser processing unit 2. The machining determination unit 42 extracts, for example, the machining target area A1 assigned to the laser machining unit 2 from the machining program PR1 in FIG. The coordinate conversion unit 43 converts the coordinates of the processing target area A1 on the workpiece W into coordinates corresponding to the laser processing unit 2. The coordinate conversion unit 43 converts the coordinates of the processing target area A1 on the workpiece W into coordinates of a coordinate system (XL-YL coordinate system) used by the numerical control unit 6 for numerical control of the laser processing unit 2. For example, the coordinate conversion unit 43 represents the position of the start point P1 by coordinates (XL1, YL1) and the position of the end point P2 by coordinates (XL2, YL2) in the XL-YL coordinate system. Here, the coordinate system (XL-YL coordinate system) used for numerical control of the laser processing unit 2 has the same origin and direction of each axis as the XW-YW coordinate system on the workpiece W, and (XL1, YL1) = (XW1, YW1), (XL2, YL2) = (XW2, YW2).

  FIG. 3C is a conceptual diagram showing processing for the processing target area A2 of the punching unit 3. The machining determination unit 42 extracts, for example, the machining target area A2 assigned to the punch machining unit 3 from the machining program PR1 in FIG. In addition, the coordinate conversion unit 43 converts the coordinates of the processing target area A2 on the workpiece W into coordinates corresponding to the punch processing unit 3. The coordinate conversion unit 43 converts the coordinates of the processing target area A1 on the workpiece W into coordinates of a coordinate system (XP-YP coordinate system) used by the numerical control unit 6 for numerical control of the punching unit 3. The XP-YP coordinate system is parallel to the XW-YW coordinate system in the direction of each axis, but the position of the origin is shifted.

  The XP-YP coordinate system is offset by ΔXP in the X direction and by ΔYP in the Y direction with respect to the XW-YW coordinate system. This offset amount is unique information of the punching unit 3 and is stored in the storage unit 44 in advance. The coordinate conversion unit 43 reads the offset amount from the storage unit 44 and converts the coordinates using the offset amount. The coordinate conversion unit 43 represents, for example, the center P3 of the processing target area A2 with coordinates (XP3, YP3). XP3 is represented by XP3 = XW3 + ΔXP, and YP3 is represented by YP3 = YW3 + ΔYP.

  FIG. 3D is a conceptual diagram showing processing for the processing target area A <b> 3 of the tap processing unit 4. For example, the machining determination unit 42 extracts the machining target area A3 allocated to the tap machining unit 4 from the machining program PR1 in FIG. The coordinate conversion unit 43 converts the coordinates of the processing target area A3 on the workpiece W into coordinates corresponding to the tap processing unit 4. The coordinate conversion unit 43 converts the coordinates of the processing target area A1 on the workpiece W into coordinates of a coordinate system (XT-YP coordinate system) used by the numerical control unit 6 for numerical control of the tap processing unit 4. The XT-YP coordinate system is parallel to the XW-YW coordinate system in the direction of each axis, but the origin position is deviated.

  The XT-YP coordinate system is offset by ΔXT in the X direction and ΔYP in the Y direction with respect to the XW-YW coordinate system. This offset amount is unique information of the tap processing unit 4 and is stored in the storage unit 44 in advance. The coordinate conversion unit 43 reads the offset amount from the storage unit 44 and converts the coordinates using the offset amount. For example, the coordinate conversion unit 43 represents the center P4 of the processing target area A3 with coordinates (XT4, YT4). XT4 is represented by XT4 = XW4 + ΔXT, and YT4 is represented by YT4 = YW4 + ΔYP.

  The program conversion device 7 (for example, the coordinate conversion unit 43) converts the coordinates as described above, and generates a converted machining program. FIG. 4 is a conceptual diagram showing the machining program PR1 before conversion and the machining program PR2 after conversion. The processing program PR1 includes codes (eg, G code, E code, M code, T code) corresponding to the operations of the plurality of processing parts (laser processing part 2, punch processing part 3, tap processing part 4). .

  For example, the coordinate conversion unit 43 determines the processing to be assigned to each processing unit based on a code included in the processing program PR1. For example, the E code is a code according to the processing conditions, and the T code is a code indicating a tool or the like (including the laser head 11) used for processing. These E codes and T codes are also dedicated codes for one processing portion among the laser processing portion 2, the punch processing portion 3, and the tap processing portion 4.

  When a dedicated code is specified in the machining program PR1, it is possible to determine the machining portion corresponding to this dedicated code. In addition, the machining program PR1 may include a code and a command for changing and specifying the drive axis. In this case, the processing unit corresponding to the code can be determined by specifying the processing unit corresponding to the axis driven according to the code. For example, when the axis to be driven is specified, the offset amount between the origin of this axis and the origin of the coordinate system on the workpiece W can be known, so that the coordinates can be converted based on the offset amount. For example, the processing determination unit 42 refers to related information (eg, table data) that associates a code with a processing unit or a driven axis, and determines which processing unit performs processing corresponding to the code. To do. The related information is stored in, for example, the storage unit 44, and the processing determination unit 42 specifies a processing unit to which each processing is assigned based on the related information read from the storage unit 44 and the processing program PR1.

  The processing program PR1 in FIG. 4 has blocks such as a laser processing mode, a punch processing mode, and a tap processing mode. In each machining mode, the coordinates are expressed in the XW-YW coordinate system on the workpiece W. For example, in the laser processing (XW_YW_ZW), the position of the processing target area A1 by the laser processing unit 2 is designated by three-dimensional coordinates in the XW-YW coordinate system. The coordinate conversion unit 43 converts the position of the processing target area A1 by the laser head 11 into the coordinates of the XL-YL coordinate system corresponding to the laser processing unit 2, and this processing is performed by laser processing in the converted processing program PR2. XL_YL_ZL).

  In the punching process (XW_YW_T1), the position of the processing target area A2 by the punching unit 3 is specified by two-dimensional coordinates in the XW-YW coordinate system, and the tool type is specified by T1. The coordinate conversion unit 43 converts the position of the region A2 to be processed by the punching unit 3 into the coordinates of the XP-YP coordinate system corresponding to the punching unit 3, and this processing is performed by laser processing in the converted processing program PR2. This is expressed as (XP_YP_T1). In the tap processing (XW_YW_T2), the position of the processing target area A3 by the tap processing unit 4 is specified by two-dimensional coordinates in the XW-YW coordinate system, and the tool type is specified by T2. The coordinate conversion unit 43 converts the position of the processing target area A2 by the tap processing unit 4 into the coordinates of the XT-YP coordinate system corresponding to the tap processing unit 4, and performs the laser processing in the converted processing program PR2. This is expressed as (XT_YP_T2). In this way, the program conversion device 7 generates the converted machining program PR2.

  Returning to the description of FIG. 2, the program conversion device 7 stores the converted machining program PR <b> 2 in the storage unit 44, for example. The output unit 45 outputs the converted machining program PR2 to an external device. For example, the output unit 45 is communicably connected to the numerical control unit 6, and outputs the converted machining program to the numerical control unit 6. The output unit 45 may output the converted processing program to a storage medium such as a USB memory or a flash memory. For example, the user may supply the numerical control unit 6 with the converted machining program output to the storage unit.

  In the present embodiment, the numerical control unit 6 is provided in the laser processing unit 2. The numerical controller 6 supplies a control value (eg, coordinate value) defined in the converted machining program PR2 to the servo amplifier 32. The servo amplifier 32 controls the XL axis drive unit 12 and the YL axis drive unit 13 based on the control value supplied from the numerical control unit 6. Here, the numerical control unit 6 also performs numerical control of each of the punch processing unit 3, the tap processing unit 4, and the transport unit 5. Note that the punching unit 3, the tap processing unit 4, and the transport unit 5 may each include a numerical control unit, or at least of the punching unit 3, the tap processing unit 4, and the transport unit 5. A common numerical control unit may be provided for the two.

  The numerical controller 6 supplies a control value (for example, a coordinate value in the XP coordinate system) defined in the converted machining program PR2 to the servo amplifier 33 of the punch machining unit 3. The servo amplifier 33 controls the XP axis driving unit 24 based on the control value supplied from the numerical control unit 6. Further, the numerical control unit 6 supplies a control value (for example, a coordinate value in the XT coordinate system) defined in the converted machining program PR2 to the servo amplifier 34 of the tap machining unit 4. The servo amplifier 34 controls the XT axis drive unit 27 based on the control value supplied from the numerical control unit 6. Further, the numerical control unit 6 supplies control values (eg, coordinate values in the YP coordinate system) defined in the converted processing program PR2 to the servo amplifier 35 of the punch processing unit 3. The servo amplifier 35 controls the YP axis driving unit 36 based on the control value supplied from the numerical control unit 6.

  Next, the plate material processing method according to the present embodiment will be described based on the configuration of the plate material processing system 1 described above. FIG. 5 is a flowchart showing an example of the plate material processing method according to the present embodiment. In step S1, the plate material processing system 1 acquires a processing program. For example, the automatic programming device 31 generates a machining program using an XW-YW coordinate system based on the workpiece W based on CAD data or the like. In addition, the program conversion device 7 acquires a machining program via the input unit 41. In step S2, the plate material processing system 1 determines processing to be assigned to each processing. For example, the machining determination unit 42 analyzes the machining program PR1 and identifies a machining unit that performs each machining or an axis that is driven when this machining is performed.

  In step S3, the plate material processing system 1 converts the coordinates of the processing target area on the workpiece into coordinates corresponding to the corresponding processing unit. For example, the coordinate conversion unit 43 converts the coordinates of the XW-YW coordinate system based on the workpiece W into the coordinates of the XP-YP coordinate system corresponding to the punch processing unit 3 with respect to the processing performed by the punch processing unit 3. For example, the coordinate conversion unit 43 reads information indicating the offset amount of the origin between coordinate systems from the storage unit 44, and converts coordinates using this information. In step S4, the plate material processing system 1 controls a processing unit (eg, laser processing unit 2, punch processing unit 3, tap processing unit 4) according to the converted processing program to process the workpiece.

  In the above-described embodiment, the program conversion device 7 includes, for example, a computer system. The program conversion device 7 reads a program stored in a storage device (not shown) and executes various processes according to the program. This program is, for example, based on a machining program for causing a plurality of machining units to machine a workpiece, determining a machining assigned to each of the plurality of machining units, and based on a determination result of the determination unit. The coordinates of the upper processing target area are converted into coordinates corresponding to a processing unit that processes the processing target area. This program may be provided by being recorded on a computer-readable storage medium.
