Description

  The present invention relates to a machining information management system.

  Conventionally, a processing information management system for producing products and semi-finished products manufactured in factories is known. In the processing information management system, products and semi-finished products are processed as necessary in each process while moving through several processes, and completed as products.

FIG. 4 is a schematic configuration diagram showing an example of a conventional machining information management system 90.
The processing information management system 90 includes a user / application 91, a process A system 92, a process B system 93, a process C system 94, and a product / semi-finished product 95.

  The user / application 91 collects information related to product processing by the user or application. The system 92 of the process A, the system 93 of the process B, and the system 94 of the process C respectively indicate one process for completing the product / semi-finished product 95 as a product. The process 92 system 92 includes a database 96A, a management system 97A, and a machining system 98A. Similarly, the system 93 of the process B includes a database 96B, a management system 97B, and a processing system 98B. The process C system 94 includes a database 96C, a management system 97C, and a machining system 98C. The process A system 92 will be described below as a representative.

  The database 96A stores processing information in the process A. The management system 97A has a function of managing processing in each process. The processing system 98A has a function of issuing a specific processing instruction to a processing apparatus (not shown).

Next, operations executed by the machining information management system 90 in FIG. 4 will be described.
First, the product / semi-finished product 95 is processed by the system 92 of the process A. At this time, the machining information in the process A is stored in the database 96A by the management system 97A and the machining system 98A. The product / semi-finished product 95 is then transferred to the process B system and processed by the process B system 92. At this time, the processing information in the process B is stored in the database 96B by the management system 97B and the processing system 98B. Hereinafter, the same processing operation is performed in the processes after the process C. That is, the machining information management system 90 has a database built for each process.

Further, a production system using a product agent that is provided in one-to-one correspondence with a product and has a recipe that describes the manufacturing procedure of the product is known. , See Patent Document 1).
Japanese Patent No. 3704698

However, in the machining information management system 90 of FIG. 4, a database is constructed for each process, and a unified database is not constructed for the whole (across processes). In this case, when collecting all the processing information of a certain product, it is necessary to collect necessary information by individually making an inquiry to the database of each process. In addition, since the interface and configuration of each process system are different, it is difficult to gather information by matching the interface to each process system.

Even if the system of each process can be interfaced, collecting the processing information about one product across multiple processes is different in the information management system of each product in each process. It was difficult to see if there was information I needed. This made it difficult to actually build a query against the database.

In addition, when products are processed not only in one factory but also in a plurality of factories, it is difficult to exchange information between the factories.

Also, in the process of processing a single product, when the process is divided into two parts, or when combining products / semi-products that have been processed in multiple processes, it is difficult to correlate those information. .

In addition, as a means for adding traceability information to a finished product, it was only possible to find necessary information from a plurality of systems and add it later.

Therefore, an object of the present invention is to realize a processing information management system capable of acquiring processing information for each individual product and ensuring traceability for each individual product.

In order to solve the above problems, the processing information management system of the invention according to claim 1 is:

  According to the first aspect of the present invention, processing information for each individual product can be acquired by an agent provided one-on-one with the product. Thereby, since processing information can be collected across processes for one product, traceability for each individual product can be ensured.

  According to the second aspect of the present invention, the plurality of control devices acquire the agent ID corresponding to the product ID of the processed product from the directory service unit, and the processed device is processed by the agent having the acquired agent ID.

Hereinafter, the system 12 of the process A will be described as a representative, and the system 13 of the process B and the system 14 of the process C are assumed to have the same configuration.

  The database 17A stores processing information in the process A. Here, the processing information refers to work information, parts information, facility information, and time information. The work information refers to information about what work has been performed on the product. The part information is information about what kind of part is used. Facility information refers to information indicating the status of facilities during product processing. The time information refers to information related to the date and time when processing is performed. The processing apparatus 20A is an apparatus for processing the product / semi-finished product 15.

The control device 21A issues an instruction for performing processing to the processing apparatus 20A. The control device 21A includes a management system 18A and a processing system 19A.
The management system 18A has a function of managing the processing in the process A. The processing system 19A has a function of issuing a specific processing instruction to the processing apparatus 20A.

The agent 16 is generated by a program. The generated agent 16 is provided in one-to-one correspondence with one product / semi-finished product 15. The agent 16 is responsible for collecting the processing information of the product / semi-finished product 15 provided (assigned) in a one-to-one correspondence. Details of the agent 16 will be described later.

Next, the operation executed in the machining information management system 1 in FIG. 1 will be described.
First, an agent 16 is assigned to one product / semi-finished product 15 when processing of the product / semi-finished product 15 is started. Then, the product / semi-finished product 15 assigned to the agent 16 is processed by the system 12 in the process A. When processing is completed by the system 12 in the process A, the management system 18A and the processing system 19A communicate with the agent 16 and notify the agent 16 of processing information.

The agent 16 saves the machining information acquired from the management system 18A and the machining system 19A in a machining information database (not shown) or holds it by the agent 16 itself. The processing information database will be described later. Thereafter, the same processing is performed for the system 13 after the process B.

Next, a specific configuration of the machining information management system 1 will be described with reference to FIG.
The processing information management system 1 shown in FIG. 2 includes an overall control system 30, an agent management system 40, a directory service 50, a process-specific system 100, and a network N. Here, the overall control system 30, the agent management system 40, and the directory service 50 correspond to the control computer 11 of FIG. The process-specific system 100 corresponds to the system 12 of process A in FIG. As shown in the system 12 of the process A, the system 13 of the process B, and the system 14 of the process C shown in FIG.

  The overall control system 30 is a system that performs production management of the entire processing information management system 1. The overall control system 30 includes an overall process management function unit 31, an agent generation function unit 32, and a machining information database 33.

  The overall process management function unit 31 notifies the process management function unit 101 in the process-specific system 100 of information necessary for product processing work. Further, the agent generation function unit 32 is used to generate the agent 16 in charge of each product in the agent management system 40.

  When the agent 16 is generated, the overall process management function unit 31 notifies information regarding what process the product in charge performs in which process. In addition, the overall process management function unit 31 may notify the process management function unit 101 described later of the start of work.

  The overall process management function unit 31 receives a notification of work completion of the product in charge from the agent 16 and manages the machining information database 33.

  The agent generation function unit 32 receives the request from the overall process management function unit 31, generates an agent 16 for each product to be managed, and operates it on the agent management system 40. Each of the agents 16 has an “agent ID”, and a processing target product 106 described later has a “product ID”. The agent generation function unit 32 registers information for taking the correspondence between the product ID and the agent ID in the directory service 50.

  The processing information database 33 is a database that holds management data for the entire process and data that extends over a plurality of processes.

  The agent management system 40 includes an agent 16 and an agent operation function unit 42.

  The agent 16 is generated by the agent generation function unit 32 and an agent ID is assigned to each agent 16. The agent 16 has information on the process in which the product in charge is processed, and collects processing information of the product in charge across the processes. The processing information to be collected is received from the process management function unit 101 or the processing apparatus control function unit 102.

  The agent 16 holds the collected machining information by the agent 16 itself or stores it in the machining information database 33 through the overall process management function unit 31. Further, when the processing of the product in charge is completed, all the processing information collected so far is stored in the processing information database 33, and the overall process management function unit 31 is notified of the end of the processing operation.

  The agent operation function unit 42 operates on the agent management system 40 and has a function for operating the agent 16. In addition, the agent 16 provides a function for communicating with other software.

  The directory service unit 50 has correspondence information between product IDs and agent IDs. When the agent generation function unit 32 generates the overall process management function unit 31, this information is determined and registered in the directory service unit 50.

  The network N connects the overall control system 30, the agent management system 40, the directory service unit 50, and the process-specific system 100. Each function and subsystem in each system can communicate with each other through the network N. Usually, an IP network is assumed.

  The process-specific system 100 is a system constructed by process. The process-specific system 100 includes a process management function unit 101, a processing device control function unit 102, a process database 103, a processing device 104, and an ID reading device 105.

  The process management function unit 101 has a function of managing processing in each process. The process management function unit 101 corresponds to the management system 18A of FIG. In addition, the process management function unit 101 receives a production instruction from the overall control system 30 on the upper side or the agent 16 and issues a specific processing instruction to the processing apparatus control function unit 102 in the process-specific system 100.

The process management function unit 101 stores necessary processing information in the process database 103. Further, when the work in the process is completed, the corresponding agent 16 is notified of the work completion in the process.

In response to an instruction from the process management function unit 101, the processing device control function unit 102 actually controls the processing device 104 to perform processing. The processing apparatus control function unit 102 corresponds to the processing system 19A of FIG. The processing device control function unit 102 is also connected to the ID reading device 105, receives the product ID of the processing target read by the ID reading device 105, and confirms the processing target product 106. Further, the processing apparatus control function unit 102 notifies the process management function unit 101 when the processing of the processing target product 106 is completed.

  The process database 103 is a database for storing processing information in the process. The process database 103 connects the process management function unit 101 and the processing apparatus control function unit 102. The process database 103 corresponds to the database 17A in FIG.

  The processing device 104 is a device that receives an instruction from the processing device control function unit 102 and actually processes the product to be processed. The processing device 104 corresponds to the processing device 20A in FIG.

  The ID reading device 105 is a device that reads the ID of the product currently being processed from the product ID device 107 attached to the processing target product 106. The reading result is notified to the processing apparatus control function unit 102.

  The product to be processed 106 is a product to be actually processed. The product to be processed corresponds to the product / semi-finished product 15 in FIG.

  The product ID device 107 is attached to the processing target product 106 and has information indicating which product the processing target product 106 is. Specifically, the information of the processing target product 106 is stored by an RFID (Radio Frequency Identification) tag, a barcode, or the like.

Next, operations performed in the machining information management system 1 of FIG. 2 with reference to FIG. 2 will be described.
First, the overall process management function unit 31 in the overall control system 30 determines a product to be produced in the future in accordance with a manufacturing plan owned by itself. The overall process management function unit 31 uses the agent generation function unit 32 to create a corresponding agent 16 in the agent management system 40 for each product. The agent 16 is informed of manufacturing information of the product in charge by the agent generation function unit 32. Here, the manufacturing information means products, product IDs, processing steps, delivery dates, information for processing, and the like.

  Further, the agent generation function unit 32 assigns an agent ID when generating the agent 16 and registers the correspondence between the agent ID and the product ID in the directory service unit 50. At this time, the overall process management function unit 31 also notifies manufacturing information for each process to the process management function unit 101 of the process-specific system 100.

  Next, the process management function unit 101 passes information (including the product ID) necessary for specific processing from the held manufacturing information to the processing device control function unit 102 or stores manufacturing information. The processing database control function unit 102 is notified of the location of the process database 103.

  The processing device control function unit 102 reads the product ID from the product ID device 107 through the ID reading device 105 when the product to be processed reaches its own process, and uses the product ID as a key to give any processing instructions. Find out what has been done. If a processing instruction has not been received yet, specific processing instruction information is received from the process management function unit 101. A processing method is determined in accordance with a processing instruction corresponding to the read product ID, and the processing device 104 is controlled to process the processing target product 106 to be processed. At this time, the process management function unit 101 finds the agent ID in charge of the product from the directory service unit 50 using the product ID as a key, reports the product ID and its own process to the agent 16 having the agent ID, and the agent 16 May be instructed to the processing apparatus control function unit 102 via the process management function unit 101.

  Next, when the processing of the processing target product 106 is completed, the processing apparatus control function unit 102 stores processing information based on the results in the process database 103 and notifies the process management function unit 101 of the end of processing. At this time, the process management function unit 101 also stores necessary processing information in the process database 103, and notifies the agent 16 corresponding to the processed product of the processing end and processing information. When communicating with the agent 16, the agent ID of the corresponding agent 16 is acquired from the directory service unit 50 using the product ID as a key, and a communication path is set up using the agent ID as a key. At this time, when an instruction is directly received from the agent 16 to the machining apparatus control function unit 102, a communication path with the agent 16 can be established without making an inquiry to the directory service unit 50.

  Next, the agent 16 that has received the machining information holds the machining information by itself or stores it in the machining information database 33 via the overall process management function unit 31.

  When the agent 16 finishes processing the product in charge in all processes, the agent 16 notifies the overall process management function unit 31 of the end of production of the corresponding product, and all of the products related to the corresponding product held at that time. The machining information is stored in the machining information database 33 via the overall process management function unit 31.

  When the product processing steps are separated, the agent 16 requests the entire process management function unit 31 to divide the agent 16. The overall process management function unit 31 uses the agent generation function unit 32 to create a copy of the agent 16 having information on the product in charge on the agent management system 40. At this time, the agent ID and product ID information are registered in the directory service unit 50. In this case, the information possessed by each agent 16 is the same information. In some cases, information may be divided so that each agent 16 has only necessary information. Each agent 16 continuously collects processing information after separation.

  When the product processing steps merge, the agent 16 requests the overall process management function unit 31 to collect the agents 16 together. The overall process management function unit 31 combines the corresponding agents of the agent generation function unit 32 into one. In this case, the finally collected agents have all the processing information that each agent has.

  Next, with reference to FIG. 3, a case where the processing information management system 1 of the present invention is used when a factory for processing a product is different will be described.

  The processing information management system 1A shown in FIG. 3 includes a factory 61, a factory 62, a factory 63, an agent 64, and a control computer 65.

  The factories 61, 62, and 63 include respective processes 66 for processing products at each factory. In the example of FIG. 3, it is shown that the process of processing the product extends over a plurality of factories 61, 62, 63. The agent 64 holds processing information of one product across factories. The control computer 65 has an application for managing processing information and the like of products manufactured across a plurality of factories.

Next, an operation executed in the machining information management system 1A of FIG. 3 will be described.
First, a product is processed at the factory 61. At this time, the agent 64 holds processing information for each product. For example, when the process extends from the factory 61 to the factory 62, it is only necessary to pass the information held by the agent 64 to the factory B. In the processes after the factory B, similar machining operations are executed.

  As described above, according to the present embodiment, processing information for each individual product can be acquired by an agent provided one-on-one with the product. Thereby, since processing information can be collected across processes for one product, traceability for each individual product can be ensured. For example, the traceability of a product can be ensured by writing processing information on an ID tag or the like and shipping it together with the product.

  Further, the plurality of control devices 18A to 18C acquire an agent ID corresponding to the product ID of the processed product from the directory service unit 50, and process information on the processed product to the agent 16 having the acquired agent ID. Can be sent.

  The manufacturing information may include at least one piece of information for product ID, product processing step, delivery date, and product processing.

  In addition, at least one piece of work information related to work performed on the product, part information related to the used parts, equipment information indicating equipment status during product processing, and time information related to the date and time when the processing was performed can be included.

  Further, even when the factories that process the products are different, it is possible to hold the processing information for each product across the factories.

  In addition, since the agent 16 in charge of the product collects processing information for each product, the load on the overall process management function unit 31 can be reduced.

  In addition, even if a failure occurs in the overall control system in which the overall process management function unit 31 operates, the agent management system in which the agent 16 operates continues to operate, thereby improving reliability without causing the entire system to stop. can do.

  Moreover, even if the process is branched or merged, information can be collected in one product unit.

  Further, when an existing system has already been completed as the process-specific system 100, an intermediary agent or an intermediary Web service function is arranged as software on the process-specific system 100 side, so that the agent 16 and the existing system are arranged. Communication and information exchange.

  In addition, the detailed structure and detailed operation of the machining information management system 1 in the present embodiment can be changed as appropriate without departing from the spirit of the present invention.
