  Hereinafter, a family operation control data creation device and method according to an embodiment will be described with reference to the accompanying drawings.

  First, the overall configuration of a bending system provided with a bending machine and a carry in / out robot will be described using FIG. 1. In FIG. 1, a multi-joint loading and unloading robot 20 is installed in front of the bending machine 10. Although the installation position is fixed in FIG. 1, the loading and unloading robot 20 may be configured to be movable along a guide rail.

  The bending machine 10 has an upper table T1 movable in the vertical direction and a lower table T2 fixed. A punch die Tp is attached to the upper table T1, and a die die Td is attached to the lower table T2. The bending machine 10 is mounted with an operation pendant 312 connected to an NC device 3 (shown in FIG. 3) described later.

  In the vicinity of the loading / unloading robot 20, a plate placement table 30, a partition plate placement table 40, and pallets 51, 52 are installed. The pallets 51 and 52 are an example of a product loading device. Instead of the pallets 51 and 52, a belt conveyor may be used as a product loading device. The number of pallets may be one, and the number is arbitrary.

  In the plate placement table 30, metal plates 301 to 303 are placed as materials for manufacturing a product. A partition plate 401 is disposed on the partition plate placement table 40. The partition plate 401 may be made of any material such as metal, wood, or plastic.

  The loading and unloading robot 20 selectively grips the plate members 301 and 302 and transfers the plate members 301 and 302 between the punch die Tp and the die die Td of the bending machine 10. The bending machine 10 lowers the upper table T1 based on control by the NC device 3 and bends the plates 301 to 303 with the punch die Tp and the die die Td.

  In the present embodiment, the bending machine 10 does not bend the plate member 303. In some cases, the bending machine 10 bends all the plates disposed on the plate placement table 30. The bending machine 10 may generate a plurality of parts by bending at least a part of the plurality of plate members.

  The loading and unloading robot 20 unloads the bent part onto any one of the pallets 51 and 52. The loading and unloading robot 20 unloads the plate member 303 onto one of the pallets 51 and 52.

  On the pallets 51 and 52, virtual holding areas 501 and 502 for setting the products are set within the movable range of the grip portion of the tip end of the loading and unloading robot 20. In the example shown in FIG. 1, the entire loading surface of the pallets 51 and 52 is a bottom surface, and a rectangular parallelepiped area having a predetermined height from the loading surface is an arrangement area 501 and 502.

  The loading / unloading robot 20 arranges each component (or plate material) constituting an assembly, which will be described later, in the arrangement area 501 or 502 based on control by the NC device 3.

It is assumed that parts A and B shown in FIG. 2 are manufactured by bending plate members 301 and 302. The plate member 303 is not bent but is referred to as a part C. Parts A, B and C are parts for constructing the assembly 300 shown in FIG. By assembling the components A~C as shown in FIG. 3, the assembly 300 is fabricated.

  As shown in FIG. 4, the server 2, the NC device 3, the display unit 11, and the operation unit 12 are connected to the CAM 1. The operation unit 12 may be a touch panel disposed on the display unit 11, or may be an operation button separate from the display unit 11.

  The CAM 1 has a display control unit 1a, an assembly creating unit 1b, and a loading pattern creating unit 1c as a functional internal configuration. The display control unit 1a, the assembly creating unit 1b, and the loading pattern creating unit 1c can be configured by software modules.

  The CAM 1 configures a family operation control data creation device of the present embodiment. The family operation control data creation method of the present embodiment is executed by the CAM 1.

  The CAM 1, the server 2, the bending machine 10, the loading and unloading robot 20, the display unit 31, and the operation unit 32 are connected to the NC device 3. The operation unit 32 may be a touch panel disposed on the display unit 31, or may be an operation button separate from the display unit 31. The display unit 31 and the operation unit 32 constitute the operation pendant 312 of FIG.

  As shown in FIG. 5, the server 2 stores plate data representing plate members 301 to 303 and component data indicating components A, B, and C generated by CAD (not shown). The CAM 1 generates bending processing data (bending processing program) for manufacturing the parts A, B, and C based on the plate members 301 to 303 and causes the server 2 to store the bending processing data.

  The CAM 1 causes the server 2 to store assembly data created by the assembly creation unit 1 b as described later. The CAM 1 causes the server 2 to store loading pattern data created by the loading pattern creation unit 1 c as described later.

  Next, how the assembly creating unit 1 b creates assembly data will be described. When the operator operates the operation unit 12 to display the family operation loading setting screen, the display control unit 1a causes the display unit 11 to display a family operation loading setting screen as shown in FIG.

  As shown in FIG. 6, the family operation loading setting screen includes an arrangement area 61 corresponding to the arrangement areas 501 and 502 shown in FIG. 1 and a pallet switching button 62. To the right of the pallet switching button 62, "1" is written, which indicates that the pallet 51 is selected.

  When the pallet switching button 62 is provided, different assembly data can be set in the arrangement area 501 of the pallet 51 and the arrangement area 502 of the pallet 52. In addition, it is possible to create different loading pattern data with the same assembly data or to create different loading pattern data with different assembly data.

  The family operation loading setting screen includes an assembly creation button 63, an assembly addition button 64, a set registration button 65, a set addition button 66, a partition plate addition button 67, a registration button 68, and a cancel button 69.

  When the operator operates (presses down) the assembly creation button 63, the display control unit 1a causes the display unit 11 to display an assembly creation screen as shown in FIG.

  As shown in FIG. 7, the assembly creation screen includes a component selection button 71 for selecting the components A to C, a component display area 72 for displaying the selected component, and a component displayed in the component display area 72. It includes cursor buttons 73U, 73D, 73L, 73R to be rotated.

  The assembly creation screen includes an assembly combination area 75, an add button 74 for adding a part to the assembly combination area 75, a determination button 76, and a cancel button 77.

  When the worker selects, for example, the part A by the part selection button 71, the display control unit 1a causes the part display area 72 to display an image of the part A. The operator operates the cursor buttons 73U, 73D, 73L, 73R to determine which side of the part A is to be directed to the loading surface of the pallets 51, 52.

  When the screen is shifted to the assembly creation screen, the top part (here, the part A) of the parts displayed on the part selection button 71 may be automatically selected.

  After the orientation of the part A is determined, the operator operates the addition button 74. Then, the image of the part A is placed on the virtual loading surface 751 in the assembly combination area 75.

  Similarly, the operator selects the part B to determine the orientation as shown in FIG. 8 and operates the add button 74 to place the image of the part B on the loading surface 751 (or on the part A). At this time, the operator operates the operation unit 12 to determine how to combine the part B with the part A.

  Subsequently, the operator selects the part C to determine the orientation as shown in FIG. 9, and places the image of the part C on the loading surface 751 (or on the parts A and B) by operating the add button 74. . At this time, the operator operates the operation unit 12 to determine how to combine the part C with the parts A and B.

  In FIG. 9, when the operator operates the determination button 76, the assembly generation unit 1b registers the parts A to C combined as illustrated on the loading surface 751 as one assembly. The CAM 1 registers assembly data indicating the assembly created by the assembly creation unit 1 b in the server 2.

  When the assembly is created as described above, the display control unit 1a causes the display unit 11 to display the family operation loading setting screen shown in FIG. 6 again. When two or more assemblies are created, the above operation is repeated.

  When the operator operates the assembly addition button 64 shown in FIG. 6, the display control unit 1a causes the display unit 11 to display an assembly installation surface setting screen as shown in FIG. The mounting surface is a surface of the plurality of surfaces of the assembly opposite to the loading surface.

  As shown in FIG. 10, the assembly installation surface setting screen rotates the assembly displayed in the assembly display area 102 and the assembly display area 102 in which the assembly selection button 101 for selecting an assembly, the selected assembly is displayed, and the like. It includes upper, lower, left, and right cursor buttons 103U, 103D, 103L, and 103R.

  Since only one assembly is created here, only one assembly is displayed on the assembly selection button 101. When a plurality of assemblies are created, the assembly selection button 101 displays a plurality of assemblies.

  The assembly installation surface setting screen includes a next button 104 for shifting to the next screen, and a cancel button 105.

  When the operator selects an assembly by the assembly selection button 101, the display control unit 1a causes the assembly display area 102 to display an image of the assembly. The operator operates the cursor buttons 103U, 103D, 103L, and 103R to determine which side of the assembly is to be set as the mounting surface to be opposed to the loading surface.

  The assembly may be automatically displayed in the assembly display area 102 when transitioning to the assembly installation surface setting screen.

  After the orientation of the assembly is determined, the operator operates the next button 104. Then, the display control unit 1a causes the display unit 11 to display an assembly installation pattern setting screen as shown in FIG.

  As shown in FIG. 11, in the assembly installation pattern setting screen, a virtual loading surface 111 corresponding to the pallets 51 and 52 seen from above, an add button 112, an add four corners button 113, and a register button 114. And a cancel button 115.

  In FIG. 11, the loading surface 111 is divided into three rows and three columns by broken lines in the horizontal direction and the vertical direction. Since the size of the assembly is known, the display control unit 1a can divide the loading surface 111 into a plurality of areas in accordance with the size of the assembly.

  When the operator operates the add button 112, the display control unit 1a causes the image of the assembly to be displayed on the loading surface 111. The operator can move the display position of the image of the assembly by operating the operation unit 12.

  When the operator further operates the add button 112, the display control unit 1a can add an image of an assembly to be displayed on the loading surface 111.

  When the operator operates the four-corner addition button 113, the display control unit 1a can display an image of the assembly at four corners of the loading surface 111, as shown in FIG. Here, the case where the assembly is arranged at the four corners of the loading surface 111, that is, the loading surfaces of the pallets 51 and 52 is taken as an example.

  In FIG. 12, when the operator operates the registration button 114, the display control unit 1a causes the display unit 11 to display a family operation loading setting screen as shown in FIG.

  The family operation loading setting screen shown in FIG. 13 is a perspective view showing a state in which images of four assemblies shown in FIG. 12 are arranged in the arrangement area 61 in FIG. When the operator operates the set registration button 65, four assemblies shown in FIG. 13 are registered as a set.

  In FIG. 13, when the operator operates the partition plate addition button 67, the display control unit 1a displays an image in a state where the partition plate 401 is placed on the four assemblies as shown in FIG.

  In FIG. 14, when the operator operates the set addition button 66, as shown in FIG. 15, the display control unit 1a displays an image in a state in which the set of four assemblies registered in FIG. Display.

  From the above, the number and arrangement of assemblies to be arranged in the arrangement areas 501 and 502 are determined.

  When the operator operates the registration button 68, the loading pattern creating unit 1 c creates loading pattern data of the assembly and the partition plate 401 arranged as shown in FIG. 15 and registers the loading pattern data in the server 2.

  A group of a plurality of assemblies and partition plates 401 arranged in the arrangement area 501, 502 (arrangement area 61) is treated as one family. It is not essential to arrange the partition plates 401 between the adjacent stages, but it is preferable to arrange the assembly set in the case of loading in multiple stages in the direction orthogonal to the loading surface of the placement area 501, 502.

  Note that there may be a case where only one set of the assembly is arranged in the arrangement areas 501 and 502. The loading pattern data includes pattern data in the case where only one set of assembly is arranged.

  The assembly data created by the assembly creating unit 1b and the loading pattern data created by the loading pattern creating unit 1c constitute family operation control data.

  The procedure for creating family operation control data will be described again using the flowchart shown in FIG. In FIG. 16, the CAM 1 (assembly creation unit 1b) creates assembly data for forming an assembly in which a plurality of parts are combined in step S1.

  In step S2, the CAM 1 (loading pattern creation unit 1c) creates loading pattern data indicating how to load a plurality of assemblies in the placement area. The loading pattern data may include arrangement data for arranging partition plates between adjacent stages.

  A procedure in which the NC device 3 controls the bending machine 10 and the loading and unloading robot 20 based on the family operation control data will be described using the flowchart shown in FIG. In FIG. 17, a case where the parts A to C are manufactured by the plate members 301 to 303 to form the assembly 300 illustrated in FIG. 3 is taken as an example.

  The NC device 3 reads family operation control data of bending processing data, assembly data and loading pattern data from the server 2. The operation unit 32 sets how many families are to be manufactured.

  When the process is started, the NC device 3 causes the loading and unloading robot 20 to transfer the plate material 301 to the bending machine 10 in step S11. In step S12, the NC device 3 determines whether or not the processing of the plate material 301 by the bending machine 10 is completed. If it is not completed (NO), the process of step S12 is repeated.

  If completed (YES), in step S13, the NC device 3 causes the loading and unloading robot 20 to place the part A in the pallet placement area designated according to the family operation control data.

  In step S14, the NC device 3 causes the loading and unloading robot 20 to transfer the plate material 302 to the bending machine 10. In step S15, the NC apparatus 3 determines whether or not the processing of the plate material 302 by the bending machine 10 is completed. If it is not completed (NO), the process of step S15 is repeated.

  If it is completed (YES), in step S16, the NC apparatus 3 causes the loading and unloading robot 20 to place the part B in the placement area according to the family operation control data.

  In step S17, the NC device 3 causes the loading and unloading robot 20 to place the component C (plate material 303) in the placement area according to the family operation control data.

  In step S18, the NC unit 3 determines whether the arrangement of the one-stage assembly is completed. If not completed (NO), the NC apparatus 3 repeats the processing of steps S11 to S18. If it is completed (YES), the NC apparatus 3 shifts the process to step S19.

  In step S19, the NC unit 3 determines whether there is a stage higher than the stage of the set of the assembly completed in step S18 based on the family operation control data. If there is an upper level (YES), the NC device 3 arranges the partition plate 401 by the loading and unloading robot 20 in step S20, and returns the process to step S11. The NC device 3 repeats the processes of steps S11 to S19.

  If there is no upper step (NO), the NC unit 3 determines in step S21 whether or not machining of all the families is completed. If the process has not been completed (NO), the NC apparatus 3 returns the process to step S11, and repeats the processes after step S11. If it is completed (YES), the NC apparatus 3 ends the process.

  Using the family operation control data generated by the family operation control data generation device and method of the present embodiment, a group of a plurality of assemblies are collectively arranged as a family within the arrangement area set in the product loading device. Thus, efficient transport to the post process is possible, and it becomes easy to manufacture the assembly in the post process.

  The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the scope of the present invention.
