  Please refer to FIG. A joint generation system (for example, an automatic programming device) 1 is configured by a computer, and includes a computer main body 2, a display device 3, a keyboard 4, a mouse 5, and the like.

  A laser processing apparatus 6 as an example of a processing machine is connected to the computer main body 2 via a LAN (Local Area Network) 20 so as to be communicable. In this example, a laser processing machine is assumed as the processing machine. However, the present invention can be applied to a processing machine that cuts the workpiece W, such as a turret punch press.

  In the laser processing apparatus 6, a portal frame 8 is erected in the vicinity of the center portion of the bed 7 extending in the X-axis direction (front-rear direction), and the upper frame 9 constituting a part of the portal frame 8 has the above-described structure. It is provided across the upper position of the bed 7. The upper frame 9 is provided with a Y-axis carriage 10 that can be moved and positioned in the Y-axis direction (left and right direction). The Y-axis carriage 10 has a Z-axis carriage that can be moved and positioned in the Z-axis direction (up and down direction). 11 is provided. A thermal processing head 12 is provided at the lower end of the Z-axis carriage 11.

  With the above configuration, the thermal processing head 12 can be moved and positioned at arbitrary positions in the Y-axis direction and the Z-axis direction. The Y-axis carriage 10 and the Z-axis carriage 11 are driven by driving means (not shown) and an NC control unit 18. NC data is transmitted from the computer main body 2 to the NC control device 18, and processing is performed based on the NC data. Note that information related to the processing is displayed on the screen 19.

  A work table 13 is provided on the bed 7 so as to be movable and positionable in the X-axis direction. In other words, the work table 13 includes a table base 16, and an X-axis guide extending in the X-axis direction is provided on the bed upper portion 17, and a traveling portion guided by the X-axis guide is attached to the table base 16. is there.

  With the above configuration, the work table 13 can be moved and positioned in the X-axis direction by being guided by the X-axis guide. Similarly to the Y-axis carriage 10 and the Z-axis carriage 11, the table base 16 is driven by a driving means (not shown) and an NC control device 18.

  A large number of beam members 14 are attached to the work table 13 at appropriate intervals, and a large number of sword-shaped workpiece support members 15 for horizontally supporting the workpiece W are planted on the beam members 14 at appropriate intervals. It is set up. Accordingly, the work W is supported on the whole plate surface on average by the support ends of the multiple sword-shaped work support members 15.

  In the above configuration, when a large number of parts P are processed from the workpiece W supported by the workpiece support member 15, the Y-axis carriage 10 provided with the thermal processing head 13 and the work table 13 that can be moved and positioned in the X-axis direction are provided. By appropriately controlling the movement, it is possible to cut a part having a desired shape from the workpiece W.

  Please refer to FIG. The computer main body 2 of the joint generation system 1 (for example, an automatic programming device or the like) has information on a graphic DB (database) 2A in which graphic shapes of parts to be processed are stored and work support members (Kenyama etc.) 15 of the processing machine. A sword mountain information memory (database) 2B in which (pitch in XY direction, number of arrangements, etc.) are stored, a CPU (Central Processing Unit) 2C, a main memory 2D for storing programs and data, a LAN ( A communication control device 2E for connecting to a (Local Area Network) and an auxiliary storage device (hard disk) 2F are provided. A display device 3, an input device (such as a keyboard) 3, and a pointing device (such as a mouse) 5 are connected to the computer main body 2.

  The joint generation system (automatic programming apparatus or the like) 1 includes a comparison unit that compares the size of the part P and the arrangement mode (for example, pitch) of the work support member 15 and a joint that connects the parts P according to the comparison result. Generating means (first generating means) for generating the part J. Moreover, in order to take out the parts P from the remaining material, a generating means (second generating means) for generating a joint portion J for connecting the parts P to each other is provided.

  The joint portion J is rectangular, and it is desirable that diagonal portions of the rectangle are connected to the parts P and the parts P are integrated. Furthermore, the comparison means calculates the ratio between the X dimension and the Y dimension of the part P and the pitch in the X direction and the Y direction of the work support member, and generates the joint portion J according to the ratio.

  The operation will be described. If the part P to be arranged is selected from the graphic DB (database) 2A and the selected part P is not dropped from the work support member (Kenyama etc.) 15 from the sword mountain information memory 2B, one or more The parts P are connected by the joint portion J so that they do not fall from the work support member 15. The target parts P to be connected can be the same parts P or different parts P, and even joint parts can be carried out by an automatic carry-out device (TK).

  A specific description will be given with reference to FIG. First, in step SA01, the joint generation system 1 (such as an automatic programming device) performs an allocation process. Thereby, the number of parts P to be processed, the arrangement position, and the like are specified.

  In step SA02, parameters are acquired from the sword mountain information memory 2B, and information (pitch, number of arrangements, etc.) of the work support member (for example, sword mountain, skid, etc.) 15 is recognized.

  In step SA03, the joint generation system 1 acquires the graphic information of the part P (size of the outer shape in the X direction, the Y direction, etc.) as part information from the graphic DB (database) 2A.

  In step SA04, the joint generation system 1 obtains the number (X number, Y number) that does not fall from the work support member (Kenyama etc.) 15. For example, it calculates | requires by the following <Formula 1> and <Formula 2>. The calculated value is rounded up after the decimal point.

Parts X dimension ÷ (Kenyama pitch x 2) = X number ... <Formula 1>
Parts Y dimension ÷ (Kenyama pitch x 2) = Y number ・ ・ ・ <Formula 2>
In step SA05, the joint generation system 1 determines whether or not both the X number and the Y number are larger than one. If both are determined to be greater than 1, the process ends. If it is not determined that both are greater than 1, the process proceeds to step SA06.

  Please refer to FIG. It is assumed that a plurality of workpiece support members 15 are arranged at a predetermined pitch PX and pitch PY in the X direction and the Y direction. Here, the parts P1, P2, P3, and P4 are cut from the workpiece W. Then, the X and Y dimensions of the part P1 are compared with the pitches PX and PY. Similarly, the X and Y dimensions of the part P2 are compared with the pitches PX and PY. The X dimension and Y dimension of the part P3 are compared with the pitches PX and PY. The X dimension and Y dimension of the part P4 are compared with the pitches PX and PY.

  In this example, the joint portion is generated as a result of the determination.

  In Step SA06, the joint generation system 1 generates joint portions J1, J2, and J3 in the X direction and the Y direction. These are rectangular (called diamond joints), and the diagonal portions of the rectangle are connected to the parts P1, P2, P3 and P4, and the parts P1, P2, P3 and P4 are integrated.

  This will be described in detail with reference to FIG. Since it is determined that both the X number and the Y number are smaller than 1, this is the case where the joint portions J1, J2, and J3 are generated. That is, the part P4 in the X direction is connected to the part P1 by the joint portion J3. Further, the part P2 in the Y direction is connected to the part P1 by the joint portion J1. On the other hand, since the part P3 falls alone from the work support member 5, it is connected to the part P2 and the joint portion J2. Thereby, the parts P1, P2, P3, and P4 are integrally connected and do not fall from the work support member 15.

  In step SA07, the joint generation system 1 performs a planing process. That is, all the parts to be processed from the workpiece W (including the figure connected in step SA06) are cut off (nesting process).

  In step SA08, when the part does not fall from the workpiece support member 5, the joint generation system 1 performs a process of eliminating the joint portion.

  The present invention is preferably provided by being stored in a storage medium such as an FD or a CD-ROM in a computer system.

  For example, in a joint generation program for generating a joint part in a locus related to processing of a part, the computer compares the part size with the arrangement mode of the workpiece support member, and the parts according to the comparison result A joint generation program is stored in a storage medium.

  In a joint generation program for generating a joint part in a locus related to processing of a part, the computer is caused to function as a generation unit that generates a joint part for connecting the parts together in order to take out the part from the remaining material. The joint generation program is stored in a storage medium.

The present invention is not limited to the embodiments of the invention described above, and can be implemented in other modes by making appropriate modifications.
