Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a process organizing device used for organizing a process for assembling printed circuit boards, for example.

(Prior Art) In the manufacturing process of a product, especially in a process that mainly involves manual labor, the organization of the process affects the production efficiency of the product. For example, in the manufacturing process of printed circuit boards, in order to mount parts such as resistors and capacitors on the printed circuit board, the workers who assemble these parts are assigned to the optimal process according to their skill level, etc. The process is organized to be highly efficient. In this case, the printed circuit board manufacturing process involves assembling a wide variety of parts, not just the ones mentioned above.
Every time the parts change, it is required to organize the optimal process in a short time.

However, in actual process organization, the process is organized based on the experience and intuition of the operator, and as a result, the process organization results vary depending on the operator, and operators have to repeatedly discuss process organization with each other, which takes time. The reality is that the final process is determined by

Therefore, it takes a long time to organize the process, and the result of the process organization is not necessarily optimal. Moreover,
Process organization cannot follow frequent changes in parts, which causes waiting in the manufacturing process and reduces production efficiency.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a process organization device that allows even a person other than a process organization expert to organize a process with high production efficiency in a short time.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a parts grouping means for grouping each part constituting a product into parts having the same attribute based on information regarding these parts, and a part grouping means for assembling the product. parts distribution means for distributing each part grouped by the parts grouping means to each worker based on information about each worker; and a parts distribution means for distributing each part to each worker based on information about each worker; The above-mentioned method is provided with a worker arrangement means for determining the arrangement and a means for assembling parts for determining the order of assembly of each worker distributed by the parts distribution means based on information on these parts. This is a process organization device that aims to achieve the following.

(Function) By providing such a means, each part constituting the product is grouped into parts with the same attribute by the parts grouping means, and each of these grouped parts is grouped based on information about the worker. The parts are distributed to each worker by the parts distribution means.

Then, each worker is assigned to each manufacturing process of the product by the worker placement means based on the information about each worker, and the assembly of each part by each worker is determined in the order in which the parts are assembled by the means. Determined based on part information.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a process organization device, and FIG. 2 is an external view of the device. In the same figure] is a mouse, 9 is a board, and these are the mouse 1 and the keyboard 2.
are both connected to the input/output interface 3. or,
4 is a display, and 5 is a printer, both of which are connected to the input/output interface 3. On the other hand, 6 is a processing engine, and this processing engine 6 is connected to the human output interface 3. Further, a database 7 and a rule base 8 are connected to the processing engine 6, and among these, the database 7 is connected to the human output interface 3.

As shown in FIG. 3, the database 7 stores information on boards, parts to be mounted on the boards, and operators.

For example, information about a board includes size, component parts, and production quantity, and information about assembly as a part includes shape and type.

Characteristic 1 Assembly is position and working time 1 Furthermore, Rating 1 is the difficulty of the work, and information for the worker is skill level, strengths/weaknesses, and margin for work. Further, as shown in FIG. 4, the rule base 8 stores parts grouping rules, parts allocation rules, work arrangement rules, and assembly order rules. However, by executing processing according to each rule stored in the rule base 8, the processing engine 6 has the following functions.

In other words, by executing the parts group grouping rule, each assembly functions as a parts grouping that groups parts into parts with the same attributes based on information about these parts, and information about each worker who assembles the product. Function as a parts distribution means to distribute each part grouped by the parts grouping function to each worker based on the parts grouping function, and work to assign each worker to each manufacturing process of the product based on information about each worker It also functions as a means for assembling parts that determines the order of assembling parts distributed to each worker based on information on these parts distributed by the parts distribution function. Further, a process evaluation section 9 is provided and connected to the database 7 and the human output interface 3. This process evaluation unit 9 receives the process organization result obtained by executing each rule of the processing engine 6, and from this process organization result, determines the operation rate, lead time, number of work in process, number of production, waiting time, etc. of the process and organizes it. It has the function of evaluating the processes that have been carried out.

Next, the operation of the apparatus constructed as described above will be explained with reference to the knitting process diagram shown in FIG. First, information regarding the board and assembly components constituting the product is entered manually from the keyboard 2. That is, the size of the board, the component parts, and the production number are manually entered from the keyboard 2, and for assembly, one type of part shape, one characteristic, the position, the working time, etc. are entered from the keyboard 2. Each piece of information entered manually is stored in the database 7 through the input/output interface 3. Further, information regarding the worker, that is, skill level, good/bad manual work, and margin rate are entered from the keyboard 2 and stored in the database 7.

Here, as shown in FIG. 5, each part is Pl. P2...
Pn represents each worker, and each worker is represented by Wl, W2...Wj.
It is expressed as

When each piece of information is thus stored in the database 7 and a grouping processing instruction is input from the mouse 1, the processing engine 6 executes the parts group grouping rules stored in the rule base 8 and performs assembly. Group parts by the same attributes. For example, the processing engine 6 is the database 7
The information of each component PI, P2...Pn stored in is read and the polarity group consisting of the type group of IC (integrated circuit), resistor, capacitor, presence or absence of polarity and its direction, etc., and the assembly to the board are determined. Divide into each group, such as a direction group consisting of the presence or absence of a direction and the direction. By this grouping, each component is divided into groups PCI, P
It is divided into G2...PGm.

Note that information on each of these grouped parts is stored in the database 7. The grouped results are then sent to the display 4 through the input/output interface 3 and displayed.

Next, when a component distribution instruction is input from the mouse 1, the processing engine 6 executes the component distribution rules stored in the rule base 8. That is, the processing engine 6 retrieves each grouped parts PCI, PC2, and PC2 from the database 7.
. . PGm information and information regarding each worker Wl, W2, . . . Wj are read out and each worker 1W1. W2...Wj
For each part PI.

P2...Distribute Pn. In this case, each part P1゜P
2...Pn is such that each worker's work time is distributed according to the work time of each part distributed to each worker so that the work time does not exceed a predetermined pitch time, and for example, the assembly of parts is The parts that each worker is good at are allocated to each worker based on the information on their strengths/weaknesses. As a result of this distribution,
Each worker Wl.

As shown in FIG. 5, W2...Wm each have, for example, each part PIG, P29. P3 is distributed. Note that the results of this distribution of parts are stored in the database 7 and displayed on the display 4.

Next, when an instruction for worker placement is input from the mouse 1, the processing engine 6 executes the worker placement rules of the rule base 8. That is, the processing engine 6 processes each worker Wl, W2.
. . . By reading the skill level of Wj, for example, a worker with a high skill level is placed at the back of a certain process, or a work H with a high level of skill and a job H with a low level of skill are placed alternately. In this way, each worker, for example worker W8. as shown in FIG.
They are arranged in the order of W5°W21...

Next, when an assembly order instruction is input from the mouse 1, the processing engine 6 executes the assembly order rule of the rule base 8. That is, the processing engine 6 processes each worker W8. W5
．． The assembly order of each part distributed to W21... is determined. For example, the order of assembly is from smallest to largest, and for example, the order of assembly by worker W8 is P12. P 8, P 45.
P 34. P2... is determined.

Incidentally, the order of this assembly may be determined from the lowest height of the parts to the highest height of the parts. As a result of the above, a process organization result is obtained, stored in the database 7, and displayed on the display 4.

By the way, as described above, process organization is obtained by executing each rule, and each of these rules is given a priority. Here, to explain the parts grouping rule as an example, as shown in FIG. 6, the groups are divided into type groups as described above.

When divided into polar groups and direction groups, for example, the parts group belonging to the type group are the parts group A1 which belongs only to the type group, the parts group B1 which belongs across the polarity group and the direction group, respectively.

B2, and a component group C that belongs to both the polarity group and the direction group. Therefore, when giving priority, the rule that determines parts group A has the highest priority, followed by parts group B1. The rules for determining B2 are followed by the rules for determining component group C. Therefore, rules are used in order of priority.

Next, when a process evaluation instruction is input manually from the mouse 1, the process evaluation section 9 reads the process organization results from the database 7 and obtains the operating rate, lead time, number of work in progress, number of production, waiting time, etc. of this process. .

Then, the process organization results and process evaluation results are sent to the printer 5.
It will be sent to and printed out.

In this way, in the above embodiment, each part PI, P2
. . . Pn is grouped by the same attribute, and each of the grouped parts is assigned to each worker Wl.

Distribute to W2...Wj, then each worker Wl, W2...
- Determine the placement of Wj in each process and each worker Wl.

Since the order of assembly of each part for each W2...Wj is determined, even a beginner in process organization can organize an optimal process in a short time. In this case, the organized processes can be organized to have high production efficiency based on the relationship between each part and each worker. Furthermore, even if parts are changed, the optimal process can be reorganized in a short time taking into account the changed parts, and no waiting will occur in the manufacturing process.

Note that the present invention is not limited to the above-mentioned embodiment, and may be modified without departing from the spirit thereof.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a process organization device that can organize a process with high production efficiency in a short time even without the consideration of a specialist in process organization.
