2. Description of the Related Art Generally, simulation has been one of the important applications since the early days of computer utilization. Describe complex or uncertain systems,
Various simulations are considered as a method for predicting and calculating the future results of the system. Among them, various evaluations are being performed on production systems and factory lines by simulation without using actual machines and materials. As a method for modeling and evaluating such a production system, a discrete system simulation targeting a discrete event system is known.

The discrete event system is a system in which the state changes by the occurrence of an event called a state change of the system at a specific time point, and the analysis of the discrete event system is congested in various meanings. It is an analysis of the phenomenon.

Corresponding to discrete events are continuous events,
A continuous event is a model that can be described by a differential equation.

A simulation of a discrete event system is a discrete system simulation, and this discrete system simulation is used for simulation of production facilities, physical distribution systems and the like. The most frequently used simulation of this production equipment, logistics system, etc. is the simulation based on the queuing model.

The central concept of the discrete system simulation is a mechanism for managing what kind of events occur in what order and is called an event list. The procedure for executing the events scheduled in the event list in order from the earliest is called event processing logic.

For example, if a work (workpiece) flows at a constant interval in a machining cell, there are events such as the arrival of the work in the machining cell, the event that the work is set in the machining machine, and the event of machining start. These will be registered in the event list, and these events will be executed in the order in which they were registered in the event list.

A discrete system simulation can show the flow of things, the control logic of the system, and the dynamic behavior of the system. Even with a deterministic system without stochastic fluctuations, it is often difficult to look hundreds of steps ahead, and simulation is effective in this case. In particular, in a system including uncertain factors, various situations can be evaluated by trying stochastic fluctuations on simulations.

The discrete system simulator is a device in which a model is prepared for limiting a problem area and performing a discrete system simulation for a specific purpose. For example, in the production process simulator, element models of a processing machine and a conveyor are prepared in advance in order to model a processing and assembly line in a factory, and a simulation model can be easily created. By using this discrete system simulator, the development period of the simulation model can be shortened.

In addition, the production process simulator has a function of expressing an actual motion by animation, so that the validity of the model and the error of the simulation program can be intuitively detected. This animation function is effective for shortening simulation verification.

As a language for describing such a simulation, there are GPSS, SLAM and the like, and for a discrete system simulator, there are WITNESS and the like, which are described in "Measurement and Control" Vol. 30, No. Two
1991, p101-114.

In the production process simulator, it is extremely important that the simulation is easy to carry out.
In the case of the factory line, the test using the actual product
Evaluation is possible. Therefore, this kind of simulation needs to be much cheaper than the actual one, and to collect and evaluate data quickly and accurately. In addition, it is required that the model can be easily modified. Since the cost of simulation can be considered as the amount of risk avoidance and the improvement of design performance, investment must be limited.
Therefore, in many system designs, simulators
It remains an auxiliary tool.

The simulation method enables verification in advance at the time of designing, and enables systematic design that relies on intuition and experience up to now to have objectively backed design, which enables optimum designing of production systems and Effective for operational improvement. In order to increase the operating rate of the production system, it is necessary to construct a system that operates by taking into account all information from the entire factory and from the order received to the delivery.

[0014]

By the way, there are various kinds of equipment constituting the production system depending on the type of industry, process, and product. Most of the facilities are automatic machines and are controlled by the sequence controller. Such a general-purpose control device is called a programmable controller. Programmable controllers are widely used as dedicated computers suitable for controlling discrete production systems.

As the production system becomes complicated, it becomes necessary to manage the abnormality detection of the equipment, the output information of the product and the like as a whole system in addition to the control of the equipment.

There is also a demand for a flexible automated production system in which a single product represented by a mixed flow production system is used to flow one product of various types.

New problems in the production system are also emerging. For example, from factory productivity such as cost and operating rate, it is required to tackle issues such as waste, environmental impact, and product recycling throughout manufacturing activities. In order to cope with this new cost, it is strongly required to examine the whole system using detailed quantification and model simulation at the planning stage.

Therefore, it is necessary that the simulation result of the entire production system can be efficiently reflected in the mounting of the control device of each equipment.

However, the conventional system technology of this type has the following problems. 1) Since the simulation model of the whole production system and the model of the actualized equipment are different, it is not possible to design by directly using the simulation information, and only limited parameter values can be used. In addition, there is no way to design a complicated control system such as a mixed flow production system with a consistent model from basic to detailed. 2) The simulation model of the entire production system is
The more detailed it becomes, the more complicated it becomes, and the more likely it is that the programming design is only for simulation. The simulation program is completely different from the facility control program and needs to be recreated. 3) Since the simulation model of the entire production system and the actual embodied equipment model are different, when the actual equipment program is changed, the simulation program cannot be changed one-to-one. 4) In a system design in which a host computer and equipment machines are connected by a network, a language and model that equipment designers and information processing system designers can see in common are required. Since there is no such thing, simulation has stopped solving individual issues that differ from position to position.

Therefore, the present invention provides a model in which a control model of the equipment to be controlled and the control device and a simulation model capable of simulating the entire factory are integrated.
It aims to provide an extremely efficient environment for designing, operating, maintaining and renewing production equipment.

FIG. 3 shows details of the component insertion section 20 shown in FIG. In FIG. 3, the component insertion portion 20
Is a loading conveyor 21, an automated guided vehicle 22, a component insertion line 23, mounting machines 24-1 to 24-4, and a unloading conveyor 25.
It is configured to include.

Here, the loading conveyor 21 carries in the printed circuit board before component insertion.
1 carries in a printed circuit board in lot units.

The automatic carrier 22 receives the printed circuit board carried in by the loading conveyor 21 and automatically conveys the printed circuit board along the component insertion line 23 according to a predetermined route, thereby mounting machines 24-1 to 24-24. -4, the printed board on which the component is mounted is discharged to the carry-out conveyor 25.

The mounting machines 24-1 to 24-4 are arranged along the component insertion line 23, and mount the components on the printed circuit boards conveyed by the automatic conveyance vehicle 22, respectively. Here, in this embodiment, four mounting machines 24-1 to 24-4, that is, the mounting machines A to D, are arranged, and different components are respectively inserted into the printed circuit board.

And is subjected to soldering processing.

The transportation route of the automatic guided vehicle 22 is determined for each product. For example, the product of product number 1 is
The mounters 24-1 to 24-4 are passed in the order of A-C-B-D, and the mounters 24-1 to 24-4 mount the components.

A production simulator for simulating the entire production system is realized by a personal computer having the configuration shown in FIG.

In FIG. 4, the personal computer comprises a central processing unit (CPU) 41 and a main storage unit 4.
2, the keyboard 43, the mouse 44, and the image memory 45 are connected to the internal bus 47.
Is connected to the display 46.

Here, the personal computer shown in FIG. 4 functions as a production simulator by the CPU 41 executing a predetermined simulation program stored in the main storage unit 42 and commands and data input by the keyboard 43 and the mouse 44. Operate. And
The simulation by the production simulator is displayed on the display 46 via the image memory 45.

The models prepared in the production simulator as the model classes are workpieces, supply ports, discharge ports, processing machines, buffers, automatic guided vehicles, conveyors, and the like.

The procedure for modeling the production line shown in FIGS. 2 and 3 by the discrete system simulator having such a production model is as follows. 1) The mounting machines 24-1 to 24-4 are represented by processing machines which are classes of models prepared in advance. 2) These models are placed in the virtual factory space for simulation at the same scale as the actual scale. This will be the same as the actual factory layout. Here, the operation of arranging each model is interactively performed using the mouse 44 on the screen of the display 46. 3) Define the product flow that indicates the order in which the workpieces are to be flown to the model placed in 2). Here, it is the message signal that actually flows between the models, and the model knows that the work is brought by receiving this message. 4) Give parameters to the model. If the model is, for example, a conveyor, the parameters are the total length, the transport speed, and the like. 5) Describe the operation logic for the model. The logic of this operation describes, for example, a procedure for determining an output destination in a conveyor according to conditions such as other buffers. In other words, this procedure is described according to the situation, such as selecting the output with the least work accumulated in the buffer. 6) Set the simulation execution time, display interval, etc., and start the simulation.

With the above procedure, the production system shown in FIGS. 2 and 3 can be modeled and simulated on the display 46 of the personal computer shown in FIG.

Here, if the parameters of each model are set correctly, the flow and movement of the work, the processing machine, the carrier, etc. can be confirmed by animation. However, if the parameter settings of each model are incorrect, an error will occur.

As described above, the simulation of the production system shown in FIGS. 2 and 3 is started, whereby the operating time of this production system, the average residence time of the work, the maximum waiting time of the work, etc. are calculated. , Output the calculation result.

As a result, it is possible to know whether this production system has sufficient equipment for the expected production amount and which bottleneck is present. Therefore, this production simulation can be used for the basic design of the production line.

FIG. 5 shows an example of the data structure of the parameters representing the above model. The data structure shown in FIG. 5 shows the data structure of the processing machine, and the mounting machine shown in FIG. 3 can be represented by the model of the processing machine shown in FIG.

FIG. 6 is a flow chart showing the dynamic control of the above model. That is, FIG. 6 shows the dynamic control of the model of the carry-out conveyor 25 shown in FIG. 3. First, when a work is input from the control point (step 101), the work is conveyed at the set speed. (Step 102), the work is output to the output (1) or the output (2) according to a predetermined route logic (Step 103). Then, it has the next work (step 104) and returns to step 101.

Such a control logic is finally expressed in the form of a language and can be executed on the above-mentioned production simulator.

Although the production simulator has been described in the above description, the facility operation simulator will be described next.

The equipment operation simulator is also realized by the personal computer shown in FIG. However, this equipment operation simulator is different from the model of the discrete system simulator such as the production simulator described above, and describes the operation of each machine to perform the operation simulation.

The movement of each machine in the equipment operation simulator is such that the equipment machine in the virtual space (three-dimensional space) moves between designated points. Further, in this equipment operation simulator, in addition to the movement of each machine, chemical reactions and temperature changes in each machine are modeled and expressed.

The procedure of modeling in the facility operation simulator is as follows. 7) The processing machine etc. that is the target of the equipment operation simulator is divided into parts and created by CAD. Here, the part is created as a unit in which the processing machine moves. In order to express the movement of things in the simulator, shape elements are defined by the movement unit,
The joint structure of the moving parts must be defined. A device is defined as a single moving object in which parts are connected by joints. Here, the joint has parameter information regarding motion, velocity, and the like. Also, there are two types of joints, a rotation axis and a parallel movement axis. For example, a 6-axis robot arm has at least 7
It can be expressed by one part and six joint parameters.
The processing machine is composed of one or more devices. 8) Define and describe physical states such as part movements and temperature changes. In the simulation, the three-dimensional movement is represented by geometrical coordinate conversion. 9) By giving initial values, joint parameters and time, the moving position of the part is determined. 10) Define a controller that controls this machine. For example, the controller that controls this machine is defined as a programmable controller. 11) Define input sensors and output actuators (eg, motors) of the controller. 12) Define input / output of the controller. That is, the meaning of input / output of the controller is described.

Here, a specific example of modeling of the equipment operation simulator will be described by taking the carry-out conveyor 25 shown in FIG. 3 as an example.

FIG. 7 is a CAD drawing of the carry-out conveyor 25 shown in FIG. In FIG. 7, the shape of each component is represented by a three-dimensional graphic. In FIG. 7, the sensor (sensor 1) 203-1 is a substrate (workpiece).
It is to detect that 205 has arrived at the position of the conveyor belt 204.

Further, the sensor (sensor 2) 203-2 is
It is to detect that the substrate (work) 205 has been passed from the conveyor belt 204 to the next step.

The motor (motor M) 202 drives the conveyor belt 204, and rotates while the substrate (work) 205 is on the conveyor belt 204, and rotates when the substrate (work) 205 disappears from the conveyor belt 204. To stop.

The carry-out conveyor 25 is controlled by the programmable controller 201. Here, the sensor (sensor 1) 203-1 and the sensor (sensor 2) 20
3-2 is an input to the programmable controller 201, and the motor (motor M) 202 is set to an output from the programmable controller 201.

The operation of the carry-out conveyor 25 is set so that the conveyor belt 204 moves at a constant speed while the motor (motor M) 202 is rotating.

FIG. 8 is an I / O table that defines the inputs of the programmable controller 201.
Is an I / O table that defines the output of the programmable controller 201.

As shown in FIG. 8, the programmable controller 201 defines a sensor (sensor 1) 203-1 and a sensor (sensor 2) 203-2 as inputs, and defines their signal names as S1 and S2.

Further, as shown in FIG. 9, the programmable controller 201 defines the motor (motor M) 20 as an output, and defines its signal name as M.

Programmable controller 20 described above
The operation No. 1 is described as a dynamic state of the programmable controller 201 in the form of language or chart.

FIG. 10 shows an example in which the operation of the programmable controller 201 described above is described in the form of a chart.

As is apparent from FIG. 10, when the substrate (workpiece) 205 is detected by the sensor (sensor 1) 203-1, the signal S1 rises, whereby the signal M rises (ON) and the motor (motor M). ) 202 starts rotating, the conveyor belt 204 starts moving, and the substrate (work) 205 is conveyed in the direction of the arrow in FIG. 7. When the substrate (workpiece) 205 is detected by the sensor (sensor 2) 203-2, the signal S2 rises (O
FF), which causes the signal M to fall, the motor (motor M) 202 to stop rotating, and the conveyor belt 204 to stop moving.

By the way, in this embodiment, the simulation of the entire production system is executed by linking the facility operation model with the production simulator model.

For example, the carry-out conveyor 25 is converted into a production simulator model and incorporated as a part of one production line. The board loading occurs from the production simulator side and executes the operation described in the equipment operation model. When the board moves from the carry-out conveyor 25 to the next step, the production simulator is notified of the event.

Although the carry-out conveyor 25 has been described in the above description, the other equipments are similarly modeled and the simulation is executed.

With such a configuration, it is possible to easily execute a production simulation including detailed equipment operation.

By the procedure up to this point, data (static description) and procedure (dynamic description) of the controlled object and controller
Will be created in two simulators, a production simulator and an equipment operation simulator. The transition moves to the stage of detailed design and implementation of individual equipment.

FIG. 11 shows an example of a system configuration used at the stage of detailed designing and mounting of individual devices.

In FIG. 11, this system includes a personal computer 30 having a display 303-1.
3 is used to connect the facility control target 302 to the personal computer 303 via the programmable controller 301, and is necessary for performing detailed design and implementation of individual devices on the personal computer 303. A database 304 for storing data is connected and configured.

In the system shown in FIG. 11,
The information necessary for the detailed design of control of individual equipment is extracted from the simulator model and converted into electric circuits and control programs.

The procedure will be described below. 13) Output the control flow of the target device in SFC (sequential function chart) format. 14) Refine this output SFC. 15) Convert this detailed SFC into a ladder language that can be executed by a programmable controller.

FIG. 12 shows the carry-out conveyor 25 shown in FIG.
2 shows an example of SFC describing the control of the above. The SFC shown in FIG. 12 is converted into the ladder chart shown in FIG.

The actual machine adjustment and actual machine operation are performed by the control program converted and generated as described above.

By the way, in this embodiment, after the actual machine is operated, the design data and the design knowledge are reused by the following procedure. 16) The created electric circuit and control program are reused as a template.

In order to reuse the created electric circuit or control program as a template, the simulation model, the description of the dynamic state, the SFC in the middle, and the final ladder chart are associated with each other and the data is stored in the database.

FIG. 14 shows an example of the data structure of the template thus constructed.

In the template shown in FIG. 14, when the simulation parameters are changed, the relevant ladder language portion is rewritten.

For example, when the speed of the conveyor in the model is changed, the parameter of the rotation speed of the motor can be obtained by calculation in the actual machine. As the number of templates increases, only the difference between the template and the new model needs to be newly programmed, so that design changes can be made efficiently.

Here, the greater the number of reused parts, the more automatically the program can be generated, and as a result, the design efficiency is further improved.

Further, according to this embodiment, the simulator of the design tool and the mechanical, electrical, and control CAD can be integrated to efficiently execute the design and maintenance.

Also, since the movement on the simulation and the movement of the actual equipment can be made exactly the same, the operating rate and the production plan of the factory are predicted on the display, and the production line exactly the same as the model is produced in the factory. You will be able to do that easily.

Furthermore, in operation, scheduling and planning can be performed by the production simulator.

As described above, in the above embodiment, by performing the steps 1) to 16), the model of the entire production facility and the model of the individual equipment can be integrated to perform the simulation. This makes it possible to efficiently design, operate, and update control programs for individual equipment, as well as design, operate, and maintain production equipment.
It can provide an extremely efficient environment for renewal.

[0105]

As described above, according to the production equipment design and operation support apparatus and method of the present invention, the production simulator models the entire production equipment to perform simulation, and the equipment operation simulator allows individual equipment to be simulated. Since the equipment is modeled and simulated while communicating with the production simulator, and the control program for each equipment is created and maintained according to the simulation result of the equipment operation simulator, the production equipment is designed, It is possible to provide an extremely efficient environment for operation, maintenance and renewal.

Further, the present invention has various effects as described below. 1) Efficient control program design can be performed by simulating with the integrated model. A control program can be generated by converting the simulation internal information. 2) By creating the created control program as a template and registering it in the database, it can be associated with the production simulation data, and can be reused for improving the system and can be efficiently reused. 3) As a man-machine interface, it is possible to design using animation, and by programming the movement of the animation, it is possible to generate data and programs that make the actual machine operate in the same way. 4) When the parameters of the actual machine are changed, they can be reflected in a one-to-one correspondence with the model of the production simulation, so the error that the actual equipment has can be incorporated into the simulation model and corrected easily. 5) Detailed program design and creation are possible even when there is no actual control target, and the creation program can be easily transferred to actual equipment.
