Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a process control method, and is particularly applicable to a seven-step manufacturing system in which a product is placed on a transport jig and transported, processed, assembled, or inspected. , a process control method that manages information such as manufacturing specifications, work processes, and work results% type It is manufactured by flowing. However, the specifications for manufacturing differ for each product, and as the number of products increases, the amount of information will continue to increase. Management is becoming increasingly complicated.

[Conventional technology]

In conventional process control methods, each piece of equipment had a file containing processing conditions and programs related to the target product.

For example, as shown in Figure 3, the product to be manufactured 1 (product A) is manufactured by each facility] 0, that is, processing equipment X1, assembly equipment Y, and inspection equipment Z.
When the process goes through the steps in the order of
Processing conditions 'P(X.

A) is stored in file 11 together with the processing conditions of other products, and assembly equipment Y stores the assembly program P(Y, A) for product A.
) in file 12 along with other product assembly programs,
In inspection equipment Z, inspection conditions P(Z, A) for product A are
They were kept in File 3 along with the inspection conditions for other products, and were read out and used by product personnel when they started work on each piece of equipment.

In addition, the inspection results R (Z, A) from the inspection equipment Z were output to a file 8 such as a floppy disk.

In order to manage the progress of the products, K attached a control form 9 to each product he was distributing, instructing the order of the process and writing in the work history such as work date and time.

[Problem that the invention seeks to solve]

In the conventional process management method described above, as the number of types of products increases, the capacity of work condition files and program files for each piece of equipment becomes insufficient. In particular, when the file is a 70-piece disk, the disk rack must be changed for each product, which is a major hindrance to automation and unmanned operation. Furthermore, when changing the conditions or programs for a product, if there are many identical pieces of equipment, it is necessary to change each piece of equipment one by one, which requires a huge amount of effort and time.

Process instructions that rely on control sheets are a major obstacle to automatic transportation from equipment to equipment.

Also, in order to manage the progress of the product, the data written on the control form must be input into a separate EDP system.
The management and the number of crabs brought in for this purpose were not to be underestimated.

Furthermore, since each manufacturing facility outputs a separate file for each product, it takes a lot of time and effort to aggregate the work results and manage the files.

[Means for solving problems]

The process control system of the present invention includes a manufacturing specification management device that writes manufacturing specifications, process procedures, and logs for equipment necessary for production on a readable/writable portable memory card; 7+) - A transport device that reads the process steps written on the card and transports the product to be manufactured and the transport jig on which the portable memory card is mounted to the next process, and a transport device that reads the process steps written on the card and transfers the manufacturing specifications and equipment specifications from the portable memory card. The present invention is characterized in that it includes manufacturing equipment that has a function of reading programs and writing work results to the portable memory card.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a simple embodiment of the present invention,
It shows the overall structure and flow.

First, manufacturing specification data for all equipment corresponding to the product to be manufactured is written into the portable memory card 2 by the manufacturing specification management device 4.

Here, what is written by the manufacturing specification management device 4 is:
The order number 3]1 product code 32, current process number 33, process number 34, equipment group code 35, specification section pointer 36, and specification storage section 22 shown in FIG.

The portable memory card 2 with necessary information written thereon, together with the product to be manufactured 1, is placed on a transport jig 3 such as a tray or pallet and begins to flow through the manufacturing process. The conveyance device 7 reads the current process number 33, the corresponding process number 34, and equipment group code 35 from the memory card 2 via the portable memory card reader/writer 6, determines the next process, and selects one manufacturing equipment for the next process. Transport to.

Each manufacturing equipment 5 reads the memory card 2 through a portable memory card reader/writer 6, obtains manufacturing specifications for the corresponding process, and performs the work. What is read by each piece of equipment is the order number 31, product code 32, current process number 33, process number 34, equipment group code 35, specification section pointer 36, and specification storage section 22 indicated by the specification section pointer. . After the work is completed, the work results information is stored in the memory card 2 via the portable memory card reader/writer 6.
After writing the result information, the product to be manufactured 1 and the transport oil tool 3 are delivered to the transport device 7. What is written by each manufacturing equipment 5 is the current process number 33, actual equipment code 37,
Actual date 38 and result data storage section 23.

When all processes are completed, the portable memory card is handed over to an external management system for aggregation, and the aggregation work is done.

FIG. 2 shows an example of a data formatter written to the portable memory card 2 of the embodiment.

The data to be written is roughly divided into four types: a basic section 20, a process description section 21, a specification storage section 22, and a result data storage section 230. The basic part 20 includes the portable memory card 2
The order number 31 is the identification code of the manufactured order product.

The process to be performed from now on is determined by the product code 32 and current process number 33.

The process description section 21 is composed of basic information regarding each work process, and exists as many times as there are processes.

The code for identifying the process is the process number 34, the equipment group code 35 is the identification code for the equipment group to be worked on in that process, and the manufacturing specification section pointer 36 is the identification code for the equipment group to be worked on in that process. A pointer is pointing to the specification storage section 22 where manufacturing specifications are stored.

The remaining actual equipment code 37 and actual date 38 in the process description section 21 are the code of the equipment that actually performed the work and the date of the work.

The specification storage unit 22 stores detailed manufacturing specifications, manufacturing parameters, and programs to be performed in each process.

In Figure 3, which shows the conventional method, processing conditions P(X, A),
This corresponds to the assembly program P(Y, A) and inspection conditions P(Z, A).

In the result data section 23, the results of actual work performed by the equipment are written in various data formats. In FIG. 3 showing the conventional method, the inspection result R(Z, A) corresponds to this.

〔Effect of the invention〕

The process control method of the present invention synchronizes the original meaning of objects and information by managing information related to production, that is, information such as manufacturing specifications, process procedures, work results, etc., using a readable and writable portable memory card as a medium. Since the portable memory card brings the manufacturing specifications and operation program with the product, there is no need to manage each equipment with its own specifications and programs.

Furthermore, by reading a portable memory card included with the product to be manufactured, the transport device can determine by itself where to transport the product to be manufactured, and unmanned transport between processes becomes possible.

Furthermore, since work results can be collected on a portable memory card, the effort and man-hours required for track record management can be significantly reduced.
