Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a machining information processing method in which a plurality of functional subsystems controlling a machining line or a machining factory are collectively controlled by an integrated system.

Generally used for processing equipment and neck inspection.

A processing line consisting of equipment and other necessary equipment, or a processing factory that collects these processing lines, is controlled by a computer, and is equipped with an automatic quality control system, a production volume control system, an automatic diagnosis system, etc. Necessary information is transmitted between each system and the processing line or factory to manage the processing quality and production volume of workpieces, as well as to help discover and repair failures in each equipment. In such a processing control system, each of the systems directly controls the processing line within the scope of its respective functions.
Separate these.

It is not possible to control the relationships among multiple functional systems, which causes the problem that the system as a whole lacks stability. The present invention comprehensively controls a plurality of separated functional subsystems using a comprehensive system, thereby providing processing information that can perform stable functions in maintaining and managing a processing line or factory and guaranteeing product quality. The purpose is to provide a processing method.

In order to achieve this objective, the present invention provides flags for each of a plurality of separated functional subsystems, and the integrated system constantly scans and monitors the status of these flags to communicate with each functional subsystem. It is designed to control the transmission of necessary information.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a schematic diagram for explaining the processing information processing method of the present invention, in which 10 is a processing line, 11 is an automatic quality control system, 12 is a production volume control system, 13 is an automatic diagnosis system, and 14 is a An auxiliary control system, 15 is a comprehensive system, and 16 is an interface. The processing line 10 includes processing equipment M1 with an NC function arranged in the order of steps.
, M2 and detection side devices S1 and S2, processing line 1
The workpieces loaded at 0' are sequentially conveyed to each of these devices by a conveyor device (not shown).

In order to measure the machining dimensions of the workpiece processed by each processing device M1, M2, the necessary measuring devices are installed in each inspection side device SI, S2 corresponding to the processing location of the workpiece, and the measurements are performed by these measuring devices. The measured data is transferred to interface 1.
6 to the automatic quality control system 11. Further, the states of the processing devices M1, M2 and the inspection devices S1, S2 are sequentially transmitted to the automatic diagnosis system 13 via the interface 16. Each device in the processing line 10 is provided with a terminal display panel, and the processing line 1W is further provided with a central display panel that collectively displays the operating status of the entire processing line. The automatic quality control system 11, production volume control system 12, automatic diagnosis system 13, and auxiliary control system 14 are equipped with storage devices corresponding to each function as described below, and their use is explained in each functional system 1.
1 to 14 are autonomously executed to control the processing line 10 by function.

Further, each of the functional systems 11 to 14 is provided with flags 17 to 20, respectively, and each flag is used when each functional system 11 to 14 needs to communicate information with another functional system or the overall system 15. 17 to 20 can be erected individually. The functions of each of the functional subsystems 11 to 14 and the comprehensive system 15 will be explained below. The automatic quality control system 11 complementarily connects the processing devices M1, M2 of the processing line 10 and the inspection devices SI, S2 to provide a process in which processing quality can be assured. Based on the measurement information sent, quality information is sent to each processing machine M1, M in real time.
Give feedback to 2.

In other words, the automatic quality control system 11 includes each inspection device SI,
Based on the workpiece data and mastering data sent from S2, it is determined whether the workpiece is acceptable or not, whether the tool needs to be adjusted or not, and if adjustment is required, instructions on the amount of adjustment and actual adjustment are made. In addition to determining whether or not the detection side has been performed, the detection side apparatus also monitors itself and instructs zero point correction of the measuring equipment. For example, if the measurement data sent from the inspection side device is out of predetermined control conditions, the automatic quality control system 11 transmits a tool position adjustment command to the corresponding processing device, and the terminal of that processing device The tool position adjustment instruction lamp is lit on the display panel, and the amount of adjustment is displayed. The production volume control system 12 controls the amount of workpieces handled on the processing line 10 to economically manage the quantity in accordance with the characteristics of machining. By controlling the input of
Optimally control evaluation functions such as energy consumption and operating rate, and number of products produced per unit time.

The automatic diagnosis system 13 not only grasps and monitors the status of each device in the processing line 10 and is useful for early detection and repair of failures, but also actively controls the conditions of the processing devices M1 and M2.

Such automatic diagnostic system 13 has three main functions as described below. The first function is preventive maintenance, which totals the actual operating time of parts whose lifespans are known in advance and outputs instructions for inspection and replacement when the lifespans are nearing the end. In addition, the lifespan of parts that actually fail is calculated and used to set the next lifespan. The second method is to detect malfunctions and failures by monitoring the sequence of the main processing equipment and measuring the time from the start point to the end point of the operation sequence and from the end point to the start point of the next operation. The third function is condition control. That is,
Some machining equipment has many parameters that set machining conditions, and some of them are variable, so each condition parameter is monitored for the machining equipment, and feedback is given to ensure that the settings do not deviate significantly. will be maintained. Furthermore, the auxiliary control system 14 supplements the control functions lacking in each NC processing equipment of the processing line 10, and aggregates control information such as auxiliary control for the NC processing equipment and function generation for the NC processing equipment having an adaptive control function. Perform processing.

However, since such an auxiliary control system 14 is only something that is lacking in each processing equipment, if each processing equipment itself comes to have the necessary control functions, it can be gradually reduced accordingly and become unnecessary. It is something. The comprehensive system 15 is a system that integrates the four separate functional subsystems 11 to 14 as described above and controls their mutual relationships.

To this end, the comprehensive system 15 constantly scans and monitors the states of flags 17 to 20 provided in each functional subsystem 11 to 14, and when a flag is set in a certain functional subsystem, determines its content. It controls the necessary processing. The content of the processing can be roughly divided into two types: one is information transmission control from one functional subsystem to another, and the other is information transmission control between a certain functional subsystem and the comprehensive system 15. There is. Information transmission control between the functional subsystems and the integrated system 15 is carried out by storing the information of each functional subsystem 11 to 14 in an organized form in a storage device provided in the integrated system 15, or conversely, by storing the stored information in an organized manner in a storage device provided in the integrated system 15. It is provided to the functional subsystems 11 to 14 as necessary.
The comprehensive system 15 includes, as peripheral equipment, a magnetic disk and a disk drive for storing data and programs. It has a grade tape reader for programming, a teletypewriter and line printer for outputting data, and a magnetic tape for backing up data storage, and these are connected to the comprehensive system 15 via an interface 16. FIG. 2 shows an example of information transmission control between the comprehensive system 15 and each functional subsystem 11 to 14, where TI1 and T12 are defective product reject commands, T21 and T
22 is bad quality machine information, T31 and T32 are quality machine information that requires attention, T41 is production information by work type, T42 is parameter information for condition setting, T51 is production information by tool,
T52 indicates a tool maintenance parts replacement command, T61 and T62 program mode commands, T71 and T72 indicate quality machine information requiring attention, and T81 and T82 indicate condition control commands, among which the poor quality machine information T21 and the quality machine information requiring attention T3
1. The production information by work type T41 and the production information by tool T51 are subjected to necessary arithmetic processing in the integrated system 15 and stored in a storage device within the integrated system 15.

Note that the arrows in the figure indicate the directions of transmission of the various information described above, and information transmission to the comprehensive system 15 is performed based on the fluxes 17 to 20 of each functional subsystem 11 to 14, and each functional subsystem 11 The information transmission to . Next, a specific example of the processing information processing method will be explained.

The processing device MI is configured to output tool breakage information, sequence information, tool information, etc. to each functional subsystem 11 to 14, and also outputs machine stop commands, tool exchange commands, tool automatic adjustment commands, and workpiece loading commands. etc. are input from each functional subsystem 11-14. First, a workpiece is carried into the processing apparatus MI based on a workpiece carry-in command issued by the production volume management system 12 according to the status of the workpiece in the processing line 10, and is processed.

Sequence information and tool breakage information from the processing device MI are sent to the automatic diagnosis system 13, and as soon as an abnormality is determined, a machine stop signal is fed back.
A lamp indicating the error is lit on the terminal display panel. Further, the contents of the processing odor information are sent to the production amount management system 12 each time a workpiece is processed. The production amount management system 12 sets a flag 18 every time a certain number of workpieces are processed,
This is determined by the integrated system 15 and the production quantity information T51 for each tool is transferred to the integrated system 15. The information transferred to the integrated system 15 is processed and stored in a storage device within the integrated system 15, and when the stored content reaches a predetermined value, the integrated system 15 interrupts the automatic diagnosis system 13. Transfer the tool change command to the automatic diagnosis system 13. Based on this, the automatic diagnosis system 13 displays a tool exchange command on the terminal display panel. In addition, maintenance parts for the processing equipment MI are registered in advance in the automatic diagnosis system 13, and their usage time limit is set, and the maintenance parts reach their usage time limit by exchanging information with the comprehensive system 15. When it is determined that the automatic diagnosis system 13 has caused an interruption, the comprehensive system 15 transmits the maintenance parts replacement command T52 to the automatic diagnosis system 13, and based on this, the automatic diagnosis system 13
displays a maintenance parts replacement command on the terminal display panel.

The workpiece processed by the processing device MI is subsequently carried into the inspection device SI, and the processed dimensions of the workpiece are measured by a measuring device.

The measurement information from the inspection side device SI is sent to the automatic quality control system 11, and if the measurement information of the workpiece is outside the predetermined control conditions, a command signal to adjust the tool position is sent to the terminal display panel. will be displayed. In addition, when the measurement information of the workpiece is out of the control conditions as described above, the automatic quality control system 11 sets a flag 17 to remove the defective workpiece from the processing line 10 from the inspection device SI, and this 15, and the defective product reject command TII is transferred to the comprehensive system 15.Based on this, the comprehensive system 15 sends the production amount management system 12.
An interrupt is made to transfer the defective product reject command T12 to the production quantity management system 12, and based on this, the production quantity management system 12 controls the flow of the workpieces so as to exclude the defective workpieces from the processing line 10. The workpiece inspected by the inspection-side device SI is then sent to the processing device M2 and the inspection-side device S2, and the same processing as described above is performed. As described above, the present invention provides a comprehensive system that comprehensively controls a plurality of functional subsystems that are separated from each other, such as an automatic quality control system, a production volume control system, and an automatic diagnosis system. By transmitting the necessary information between functional subsystems and between each functional subsystem using the integrated system as an intermediary, multiple functional subsystems that were previously separated are now integrated into an integrated system and related to each other. Therefore, the processing information processing system as a whole can exhibit stable functions.
