Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an information management system for processing elements.

(Prior Art) Conventionally, for example, processing information such as I, diagonal data, etc. created for NC program data is managed by an automatic programming device in the office, printed out at the time of NC tape creation, and used for on-site work. The work instructions are handed over to the person responsible for the work.

(Problem to be solved by the invention) However, in the conventional method of managing processing information as described above, processing information only serves as a work instruction manual for workers, and in FMS, this information is not organically stored. It could not be used.

That is, for example, in a punch press for turret 1, material (material, plate thickness, size) data is used as processing information.

Clamp position data, machining time data, used mold list 1
However, for example, it is not possible to compare the list of used molds with the machine parameters, and even if the schedule data indicates that the number of materials is 5, processing information such as material type and size cannot be compared. It was not possible to issue this command to automated warehouses without limiting it.

Under the recent trend of FMS, various processing machines are organically connected for the purpose of high-mix, low-volume production, so it would be convenient if processing information could be used organically.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an information management system for a processing line that allows an NC processing machine to organically utilize machining error and input information such as processing information and warehouse information.

[Disadvantage of the invention 1 (Iζth means for solving the problem) As shown in the outline in FIG. 3. In an information management system for a processing line formed with various controllers such as the controller 5 of an automated warehouse, attached information of various controllers such as processing information of an NC processing machine and warehouse information of an automated warehouse is stored in the IC card 7 as a data file. It is characterized by forming a local database using the IC card 7 for storage.

(Function) In the processing line information management system of the present invention, various controllers 1 to 1
The attached information of the rollers 3 and 5 is stored in the IC card 7 as a data file, and a local database is formed in the IC card 7. Therefore, the attached information stored in the IC card 7 is stored in each controller 1-roller 1.3.5. It can be used in a variety of ways on other computers.

(Example) Hereinafter, the present invention will be described in detail by giving an example of the use of processing information.

J shown in Figure 2: Sea urchin, N shown as an example of an NC processing machine
A processing information management device 9a is attached to the controller 3a of the C turret punch press.

A read/writer 11 for the IC card 7 is connected to this processing information management device 9, and inside it, a processing information data file storage section 9a, a data generation product 9a, a comparison section 9b, a data generation section 9c, a data An editing department 9d is provided.

The controller 3a of the turret punch press includes therein a machine parameter storage section 3b, an NC program data storage section 3c, and an input/output section 3d connected thereto. The output horn section 3d is connected to input operation devices such as a keyboard and CRT, and input/output signal lines of a turret punch press, as well as a main controller 1 forming the FMS.
, and is connected to the controller 55 of the automated warehouse via a communication line.

As shown in FIG. 3, material data, clamp position data, machining time data, and used mold data created for the NC program data are read and written as data files in the Canadian program data file storage section 9a. It is remembered in the form of possibility. As shown in the figure, these data can be displayed on the CRT screen 13 as appropriate. In addition, it is possible to print from 1 to 1 as appropriate.

The data generation section 9a extracts NC program data and processing information from the NC program data storage section 3C and processing information delta file storage section 9a, and generates new data.

For example, as shown in FIG.
A delivery request signal Q can be outputted to the roller 5 from the controller 3 (NC device and other control devices) of the processing cell (turret punch press) in the form of material data plus the number of sheets. Thereby, the controller 5 of the automated warehouse 15 can load the predetermined material W onto the material barrel 1 21 in response to the signal Q and unload the material W to the processing cell 19.

The comparing section 9C extracts NC program data or machine parameters and machining information data from the NC program data storage section 3C or machine parameter storage section 3b and the machining information data file storage section 9a before starting machining, and compares the two. This is used to check in advance the processing to be performed.

For example, as shown in FIG. 5, the used mold data and clamp position data owned by the processing information data file storage section 98, and the mold layout and clamp position on the taresito held by the machine parameter storage section 3a are stored. After comparison, if there is a difference, the machining based on the NG program can be automatically stopped, and a message can be displayed on the CRT screen to prompt the operator to replace the mold and change the clamp position.

In the example shown in Fig. 5, in the machining information corresponding to the NC program data, the station T2O1 has a mold x
While it is specified that XX is to be used, the machine parameters actually indicate that the mold ΔΔΔ is moved into the cellar 1 and the machining conditions are different.

Therefore, in such a case, processing can be automatically stopped and a predetermined message can be output.

Note that the turret one-punch press of this example is not equipped with an automatic mold exchange device and an automatic clamp position adjustment device, and the actual mold exchange and clamp position adjustment are performed manually. Therefore, in this example, we decided to output only the message as described above, but by managing processing information as a data file in this way, it will be possible to use it in automatic mold change equipment and automatic clamp position adjustment equipment in the future. It becomes possible to respond.

Furthermore, the comparison section 9C compares NC program data, processing information, etc. for all NC programs called in the schedule program before performing the schedule call operation, By checking the machining process in advance, it is possible to prevent machining errors from occurring.

The data editing section 9d displays mold data and clamp position data on a CRT, as shown in FIGS. 6 and 7, and can edit the data as appropriate to suit the actual machine.

As described above, in the processing information management device of this example, processing information is stored as a data file, so data can be processed by the data generation section 7a, and data can be processed by the comparison section 7b.
A pre-check can be performed with the , and data can be edited with the data editing section 7c.

On the other hand, the controller 5 (see FIG. 1) of the automated warehouse 15 shown in FIG. 4 manages shelf inventory information and history information. At this time, in this example, the warehouse information can be stored in the IC card 7 as a data file, so the IC card 7
By compiling the data into a local database, it can be provided as a warehouse information collection h1, for example.

Furthermore, it is also possible to easily provide the processing information and warehouse information of the IC card 7 to other systems outside the system.

As mentioned above, in the processing line information management system of this example, I
Since the CC node door is used as a medium and the processing line information is stored in the data file, the data can be used organically as described above, and the data can be expanded and expanded in the future.

Furthermore, when used in combination with data communication, data can be exchanged using an IC card as a medium, so it is possible to easily deal with communication failures and the like.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in other appropriate modes by making appropriate design changes.

[Effects of the Invention] As described above, according to the processing line information management system of the present invention, processing information is stored in an IC card as a data file, so it is possible to check processing in advance and to send materials to an automated warehouse. It has the advantage that commands can be issued and various information can be organically used by the NC device and other devices.
