[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for creating a control program for machine tools and peripheral machines suitable for variable quantity production.

[0002]

2. Description of the Related Art In recent years, with the diversification and individualization of market needs, the necessity for high-mix low-volume production is increasing in many processing plants. Therefore, in the past, a system for variable-quantity and variable-quantity production was used in which peripherals such as a loader, robot, and work table were combined with the machine tool body, and these were organically controlled to flexibly respond to changes in the type and quantity of work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The program creating apparatus of the present embodiment creates a program for operating a variable and variable production system, which system includes at least a machine tool body (generally a turning center), a loader (a robot can also be used), It is composed of a work table, a chuck (on the main body side), and a table for the gripper replacement claws in the loader.

As shown in FIG. 1, the program creating apparatus of this embodiment is provided with a machining information input section 1 for inputting machining information of a plurality of types of works. The processing information includes data that is different for each work and data that is common to each work. The former machining information is data that differs depending on the shape of the work, and includes work information such as the work process number and the chuck or loader claw number, a machining program for each work,
It includes point data that specifies the loading or unloading position of the work in the loader or the like. The latter machining information is data of a system operation portion common to each work, and includes, for example, a common program such as a loading program, an unloading program, a work table transfer program, a work replacement program, and a claw replacement program.

Further, the program creating device includes a work information storage unit 2 for storing work information in the input machining information, a machining program storage unit 3 for storing a machining program in the machining information, and a machining information storage unit 3 for storing the machining information in the machining information. A point data storage unit 4 for storing point data and a common program storage unit 5 for storing a program common to each work in the machining information.
And are provided. Each of the storage units 2 to 5 uses a non-volatile memory so that the created data can be reused.

Further, the program creating apparatus is provided with a schedule input section 6 for inputting a schedule for continuously machining each work, for example, a work part number, a process number, the number of machining, and the like. The program creation device includes a continuous machining program creation unit 7 and a storage unit 8, and the continuous machining program creation unit 7 schedules
The workpiece information, the machining program, the point data, and the common program are integrated to create a continuous machining program for continuously machining each workpiece, and the created program is stored in the storage unit 8.

Next, a method of creating a program by the apparatus configured as described above will be described. When creating a variant production program, a common program is first input as processing information. Here, the loading program, the unloading program, the transfer program to the work table, the work exchange program, the claw exchange program, etc.
Except for the table number where the work and claws are set, there is no difference for each work and it is a program that can be used in common, so enter each program with the gripping position and table number as variable names and enter the input data. Are stored in the common program storage unit 5. Further, since these programs can be used for all works, once stored, there is no need to input them thereafter.

Next, work information is input as processing information and stored in the work information storage unit 2. Here, in FIG.
As shown in, the chuck number (or name) of the chuck or loader is set for each part number, process number, and work number. In this way, when a part number or the like is designated during processing, the required nail number is immediately known, so that processing can be started quickly.

Next, a machining program and point data are input as machining information, and these are stored in the machining program storage unit 3 and the point data storage unit 4. here,
The machining program is created by utilizing an automatic programming device, and the point data is taught in-kind by using the control device of the loader as is generally done. Figure 3
Shows an example of a machining program, and FIG. 4 shows an example of point data.

In this way, machining information of a plurality of types of workpieces is input and stored, and subsequently, a continuous machining program is created according to the schedule. Of course, if it is a repeat work that has been processed before, it is not necessary to input it again because the previous data can be used.

The continuous machining program is created by the procedure shown in the flowchart of FIG. First, in step S1, necessary schedule data is input. Here, FIG.
As illustrated in FIG. 2, the part number, the process number (first process, second process, etc.), the number of processed pieces, the table number on which various nails are set, and the table number on which the material is set are input for each work. Next, in step S2, the work information registered in advance based on the part number and the process number is searched, and if there is no corresponding information, the work information is input in step S3 and the data is stored in the schedule of FIG. A guide is displayed in brackets in the input screen. In this way, the nail number to be used and the like can be known, so that reliable preparation can be performed.

In step S4, a continuous machining program corresponding to the input schedule data is created.
Here, as illustrated in FIG. 7, the work number is used as the key data, and the data setting (N002), the calling of the main program and the sub program (N003), and the machining number count (N004) are performed according to the machining order for each work. It is specified continuously. The work number is an item provided to simplify the search process, and an arbitrary number is given to each part number and process number. By doing this, if the work number is searched, the same result as when both the item number and the process number are searched can be easily obtained.

In step S5, a data program for each work is set. Here, the claw numbers of the chuck and the loader hand, the table numbers in which they are set, and the table numbers of the materials are set based on the work number and the process number. By setting these data for each machining type prior to system operation, it is possible to deal with each machining type.

In step S6, the machining program is searched using the work number as key data, and if registered, it is set in step S7. If not registered, it is input and set in step S8. Similarly, point data is retrieved in step S9 and set in steps S10 and S11. Then, step S12
Then, the registered common program is set, and the continuous machining program is completed.

As shown in FIG. 8, the completed continuous machining program is composed of a data program and a main program. The main program controls the entire system and is composed of a chuck claw replacement program, a loader claw replacement program, a work replacement program, and a machining program. Here, the point data of each exchange program and the machining program are necessary for each work number, but the others are common to each work. Therefore, if common data is registered in advance, it can be used as it is in the case of repeat work, and a program for repeat work can be immediately created only by inputting a schedule. Further, even in the case of a new work, the system can be operated by setting the point data and the machining program.

[0020]

As described above in detail, according to the present invention, a program influenced by the shape of the work and a common program not influenced by the shape of the work are separately stored and integrated into the schedule. Since a continuous machining program is created by using it, it is possible to easily create a program for a variable-volume, variable-volume production system, reduce the burden on the programmer, prevent mistakes, and contribute to improving the system operation rate.
