DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated management method for a die casting machine and its peripheral devices.
The present invention relates to a die-casting machine capable of coping with different types of peripheral devices depending on factories and products and facilitating overall management of a casting process, and a method for overall management of peripheral devices thereof.

[0002]

2. Description of the Related Art Since the production process of die casting and important management items in the production process differ depending on the product, incidental facilities are also changed according to the casting product. Therefore, conventionally, the die casting machine and its peripheral devices are managed independently for each elemental technology unit, or the die casting machine and its peripheral devices are managed by a fixed integrated management system constructed according to the casting product. Was.

[0003]

However, in the method for managing the die casting machine and its peripheral devices for each elemental technology unit, for example, a mold temperature control, an exhaust system, a melting and hot water supply system, an injection monitor control system for a die casting machine, and the like. Since the peripheral devices are managed and operated independently of each other, not only must the operator manage multiple systems, but the management of each peripheral device also differs depending on the cast product, which makes management work complicated and There is a problem that an increase in the burden on the user causes a mistake.

[0004] In the method of management by a fixed integrated management system, the connection of each peripheral device is fixed, and its dependency, execution order, and priority cannot be changed. There is a problem that the system must be rebuilt. Further, even with the same cast product, there is a problem that it is necessary to modify the integrated management system in order to add a newly developed peripheral device or to improve an existing peripheral device, which is costly. Further, the control theory (software) of the die casting machine and peripheral devices is supplied in ROM, and is fixed to the system and hardware. To change the control theory, it is necessary to replace a ROM in which the program has been rewritten. However, there is a problem in that the content of software can be changed only by the maker of the apparatus, and thus costs are high.

The control performed by the peripheral device is performed on the input value of the device, and cannot utilize the data of another device. For example, in the mold temperature control device, in order to perform appropriate control, in addition to the mold temperature, the operation state of the die casting machine and the temperature of the molten metal in the hot water furnace are required. These data cannot be received from the control unit. To receive data, it is necessary to add a dedicated input function. However, since such an input function is provided in the control device of the die casting machine, if the mold temperature control device is provided with the same input function, there is a waste of duplication of equipment.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the related art, and can easily construct a system for managing a casting process of die casting for each casting product, and can add or modify peripheral devices. It is an object of the present invention to provide a die-casting machine and a method for managing and managing peripheral devices thereof, which can easily cope with the problem and further reduce the cost.

[0007]

In order to achieve the above object, according to the present invention, there is provided a plurality of child programs in which individual processes or highly relevant processes in a casting process control routine repeated for each casting shot are collected. Prepare, select the necessary child program from the plurality of child programs according to the casting product, create a configuration file that specifies the execution order of the selected child program, and select the child file selected in the configuration file. The system management computer controls the control of the die casting machine and its peripheral devices in the casting process according to the main program independent of the plurality of sub programs that execute the program in the specified execution order, and the selected sub program and main program Common data accessible from both sides Providing centralized management method of the die casting machine and its peripheral devices provided with data area.

Further, in the present invention, a user selects a plurality of prepared child programs for individually monitoring and controlling a die casting machine and its peripheral devices used in a die casting manufacturing process in accordance with a desired casting process. An integrated management method for a die casting machine and its peripheral devices, characterized in that an execution order of a selected child program in a routine is set.

[0009]

According to the present invention, the control of the die casting machine and the peripheral devices is controlled and managed by using an independent system management computer, and individual processes or highly relevant processes in a routine work repeated for each casting cycle are summarized. These are child programs independent of the main program. Since all processes related to hardware (peripheral devices and interfaces between the peripheral devices and the computer) are independent of the main body program and are supplied as child programs corresponding to the respective peripheral devices, the user can select and execute these child programs in the order of execution. By setting, it is possible to respond to the rearrangement of peripheral devices that differ depending on the factory or product,
Overall control of the casting process can be easily performed.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a hardware environment to which the present invention is applied. As shown in FIG. 1, the die casting machine 1 includes a plurality of peripheral devices 2A to 2A.
M is connected, and each peripheral device is connected to the system management computer 4 via the corresponding interface 3A to 3M. A RAM 5, a ROM 6, a hard disk 7, and a display 8 are mutually connected to the system management computer 4 via a bus such as a data bus. Here, the peripheral devices include a melting and hot water supply device,
Measuring device for measuring various data, mold temperature control device,
Robots for removing burrs or palletizing products to be sequentially placed on a pallet are included. These peripheral devices include those that control the die-casting machine itself and those that control auxiliary equipment of the die-casting machine such as a melting furnace. Some peripheral devices have a data input unit, a control unit, and a storage unit inside.

FIG. 2 is a diagram conceptually showing a storage area of the RAM 5 connected to the system management computer 4. As shown in the figure, the RAM 5 secures a child program storage area for storing child programs, a main program storage area for storing main programs independent of the child programs, and a common data area. In the common data area, various setting values (target value, upper limit value, lower limit value), measured value,
Comparison data and the like are stored. These data are used for controlling the flow in the measurement and control routine of the casting process according to the situation, and for comparing measured data with set values. The data stored in the common data area is accessible from both the child program and the main program.

The child program is a collection of individual processing or highly relevant processing in the main program that is repeated for each casting shot. The child programs include a control program of the mold temperature control device shown in FIGS. 4 to 9, a trigger program, a program for performing processing when the casting machine is stopped, a data collection program, a data processing program, a comparison program, and a determination result. There are an alarm output program for outputting the alarm data to the alarm device, a data storage program for storing the measurement data on the specified disk, a screen display program for displaying the data on the display screen, and the like. Can be additionally stored.

FIG. 3 shows a measurement as a main program,
FIG. 10 shows a setting example in which a small program is specifically set. The main body program is stored in the hard disk 7, but is controlled to be resident in the RAM 5 when the system management computer 4 is started. The measurement and control routines can be broadly divided into a casting process control routine and a task routine. In the casting process control routine, the child programs are sequentially executed in accordance with the settings, and the flow is controlled and the subroutine function of the main body program is performed in response to a request from the child program.

Next, a measurement and control routine will be described with reference to FIG. When the main program starts, a main menu is displayed on the display 8.
Various items including “casting process control” are written in the main menu, and the measurement and control routine shown in FIG. 3 is executed by selecting “casting process control” from the main menu. Symbol Si (i = 31, 31, 3)
3. . . ) Is each step.

When the measurement and control routine is started, it is determined whether or not conditions necessary for executing the routine are satisfied (S31). The necessary conditions are that necessary peripheral devices are connected and further necessary programs are prepared. If it is determined that all of these conditions are satisfied (S31: Yes), the process proceeds to S33. If it is determined that the necessary conditions are not satisfied (S31: N
o) Loop out to the main menu (S32).
If it is determined that the necessary conditions are satisfied (S31: Ye
s), the task counter indicating the processing number of the task (work) is set to zero (S33). As will be described later, child programs pre-selected according to the casting product are written in the configuration file in the order of execution.
The execution order of the child program corresponds to the processing number of the task.

Next, initialization is performed on the flag group FLAG_TASK which is valid only in the casting process control routine.
That is, FLAG_ROUTIN is turned off (S34). FLAG_ROUT
IN is a 16-bit flag group, and can store 16 binary states. FLGA_ROUTIN includes, for example, a TRG flag for instructing output of an injection start signal, a STOP flag for instructing output of a casting machine stop signal, and the like. These flags are stored in the common data area of the RAM 5. In S34, all these 16 flags are reset. Next, initialization is performed on the flag group FLG_TASK which is valid only within the task routine. That is, FLGA_TAS
K is turned off (S35). FLAG_TASK contains LO that instructs to exit the measurement and control routines and return to the main menu.
OP_OUT flag, CONTINUE flag to indicate that the return loop should be continued at the beginning of the measurement and control routine, RETU to indicate that the return loop should be continued at the beginning of the task routine
An RN flag and the like are included, and these flags are also stored in the common data area of the RAM 5.

Next, the TASK-th child process in the configuration is executed (S36). Since the count value of the task counter is currently set to TASK = 0 in S33, the 0th (head) TASK in the configuration file is executed. In the example of the configuration file shown in FIG. 10, the control program of the first mold temperature control device is executed. The control program is stored in the hard disk 7, and the system management computer 4 reads out the control program from the child program storage area of the hard disk 7 to the child program area of the RAM 5 and executes it. The contents of the control program of the mold temperature control device are shown in FIG. 4, and the following processing is performed.

When the control program of the mold temperature control device starts, the target value, upper limit value and lower limit value of the mold temperature set in the mold temperature control device as a peripheral device are read out by the system management computer 4. (S40
1) The read value is compared with the set value on the system management computer 4 side (S402). If the two set values match (S402: No), the control program is immediately terminated. If the two set values do not match (S402: Yes), the set value of the system management computer 4 is sent to the mold temperature control device, and the data set in the mold temperature control device is transmitted to the system management computer. The data is rewritten to the data on the fourth side (S403). That is, in the present embodiment, the setting data of the system management computer 4 has priority over the setting data of the peripheral device. Next, by sending the rewritten data from the mold temperature control device to the system management computer 4, the system management computer 4 confirms that the data rewrite has been completed (S404), and controls the mold temperature control device. Quit the program. The input of the set value on the system management computer 4 side is executed by selecting a corresponding item in the main menu.

As described above, when the control program of the mold temperature control device corresponding to TASK = 0 is completed, the process returns to the measurement and control routine shown in FIG. 3 to determine whether or not L00P_OUT is true (set). (S37). This is a determination as to whether the LOOP_OUT flag included in FLG_TASK is set or reset. The LOOP_OUT flag is a sign indicating whether to exit the measurement and control routine and return to the main menu. FLG_TASK including the LOOP_OUT flag is initially reset (S35), and the mold temperature corresponding to TASK = 0 Since the LOOP_OUT flag has not been set in the control program of the control device, the LOOP_OUT flag remains reset (S37: No). Therefore, the process proceeds to the next process, and it is determined whether or not CONTINUE is true (ON) (S38). If the LOOP_OUT flag is set during the execution of another child process (S37: Yes), the process loops out to the main menu (S32).

Determination of whether CONTINEU is true (S38)
Is a determination as to whether the CONTINUE flag included in FLG_TASK is set or reset. The CONTINEU flag returns to S34 of the measurement and control routine, and is an indicator indicating whether or not to continue the loop. FLG_TASK including the CONTINUE flag is initially reset (S35).
Since this CONTINUE flag is not set in the control program of the mold temperature control device corresponding to TASK = 0, CONTINE
The flag is in the reset state (S38: No). Therefore, the process proceeds to the next processing to determine whether RETURN is true (set) (S39). If the CONTINUE flag is set during the execution of another child process (S37: Ye
s) Returning to S34, S35, S36 and S37 are repeatedly executed. That is, the program corresponding to TASK = 0 is executed again.

The determination as to whether RETURN is true (S38)
This is to determine whether the RETURN flag included in FLG_TASK is set or reset. The RETURN flag is an indicator that indicates whether to return to the beginning of the task routine and continue the loop, and is set in the child program when it is desired to execute a certain function of the main program. FLG_TASK including the RETURN flag is initially reset (S35). In the execution program shown in FIG. 10, since this RETURN flag is not set in the control program of the mold temperature control device corresponding to TASK = 0, the RETURN flag is in a reset state (S39: N
o), and proceed to S41. If the RETURN flag is set during the execution of another child process (S39: Yes), a subroutine in the main program corresponding to the input key code is executed (S40). The programs executed here include a data screen display program for displaying measurement and control results on the display 8, a storage capacity remaining amount check program for a storage medium such as a hard disk, and the like.
There is a program for changing display conditions on the display 8 and the like. When the execution of the subroutine ends, the process returns to the beginning of the task routine (S35), and the program corresponding to TASK = 0 is executed again.

If it is determined that the RETURN flag is in the reset state (S39: No), the task counter indicating the processing number of the task is incremented to TASK = 1 (S4).
1). Next, the incremented count value of the task counter is compared with a preset maximum value MAX. If the count value of the task counter has not yet reached the maximum value MAX (S42: No), the beginning of the task routine, that is, It returns to S35. If the count value of the task counter has reached the maximum value MAX (S42: Yes), the process returns to the beginning of the casting process control routine, that is, S33. In the case of the execution program shown in FIG. 10, MAX = 8 is set. Here, the casting process control routine refers to processing for one-shot work in die casting, and the task routine refers to processing of each of a plurality of child programs executed in one shot. Therefore, when a predetermined child program is sequentially executed and a round of the casting process control routine is completed, one-shot work is completed. To manufacture a plurality of identical cast products, the casting process control routine is repeatedly executed. .

If the count value of the task counter is incremented to TASK = 1 and the count value of the task counter has not reached the maximum value MAX, the task routine is repeatedly executed. After turning off FLG_TASK (S3
5) Execute the child program corresponding to TASK = 1 (S3
6). In the case of the execution program shown in FIG.
The child program corresponding to = 1 is a trigger program and is executed. The trigger program is also stored in the hard disk 7, and the system management computer 4
Reads the control program from the hard disk 7 and executes it. The trigger program is a program for controlling hardware, and determines whether or not a trigger signal serving as a starting point of processing such as a start of a casting cycle or a stop of the die casting machine 1 has been output, and execution of a subsequent child program or main body program. It gives timing. The contents of the trigger program are shown in FIG. 5, and the following processing is performed.

When the trigger program starts, the start address of the common data area is received from the main program, and the common data area can be accessed during execution of the trigger program (S501). Next, it is determined whether the trigger signal is on (S502). When an injection signal generated at the time of injection of the die casting machine 1 is used as a trigger signal, it is determined whether or not the injection signal has been output. By detecting that the injection signal has been output, it is possible to know that the casting cycle has started. When the trigger signal is on (S502:
Yes), sets the TRG flag included in FLG_ROUTIN (S503), and ends the trigger program. When the trigger signal is not output (S502: No), it is determined whether or not the stop signal output when the casting machine is stopped is on (S504). If neither the trigger signal nor the stop signal is output and there is no key input (S506: No), the trigger signal or the stop signal is detected, or S5 is performed until there is any key input.
02, S504 and S506 are repeatedly executed. If the die casting machine 1 is operating normally, a trigger signal (injection signal) should be output at predetermined time intervals. It is determined that the die casting machine 1 has stopped. Therefore, the STOP flag included in FLG_ROUTIN is set (S505), and the trigger program ends.

If it is determined that a key input has been made in a situation where neither the trigger signal nor the stop signal has been output (S
506: Yes), if it is a key input that requires processing (S507: Yes), it is determined whether it is a key input for interrupting the measurement (S508). If it is determined that the input is a key input for interrupting the measurement (S50)
8: Yes), the LOOP_OUT flag of FLG_TASK is set, and the trigger program ends. If the key input is not a key input for interrupting measurement (S508: No), FL
The RETURN flag of G_TASK is set (S510), and the trigger program ends. For convenience of explanation, it is assumed that the TRG flag is set during the execution of the trigger program in the execution program shown in FIG. 10 (S50).
3).

When the trigger program ends, the process returns to the measurement and control routine shown in FIG. If the LOOP_OUT flag is set during the execution of the trigger program (S
49), when the execution of the trigger program ends and the process returns to the measurement and control routine, the determination in S37 becomes Yes, the measurement and control routine ends, and the process returns to the main menu. CONTIN if the LOOP_OUT flag is not set
Although it is determined whether the UE flag is set (S38), since this flag is not set in the trigger program, it is next determined whether the RETURN flag is set (S39). If the RETURN flag is set during the execution of the trigger program (S
510), the determination in S39 becomes Yes, and the process returns to the beginning of the task routine after executing the process of S40. RETURN
If the flag has not been set, the task counter indicating the processing number of the task is incremented to TASK = 2 (S41). Next, the incremented count value of the task counter is compared with a preset maximum value MAX. If the count value of the task counter has not yet reached the maximum value MAX (S42: No), the beginning of the task routine, that is, It returns to S35.

The task routine is repeatedly executed as described above. In the next task routine, a child program corresponding to TASK = 3 is executed. In the case of the execution program shown in FIG. 10, the child program corresponding to TASK = 3 is a processing program when the die casting machine is stopped, and functions when the die casting machine 1 has an abnormality. The contents of the processing program when the casting machine is stopped are shown in FIG. 6, and the following processing is performed.

When the processing program for stopping the casting machine is started, first, it is determined whether or not a STOP flag, which is included in FLG_ROUTIN and indicates a state in which a stop signal of the casting machine is being output, is set (S601). If the STOP flag is not set, the program immediately ends because the casting machine is operating normally. If the STOP flag is set in S505 of the trigger program shown in FIG. 5, a stop signal is sent to the mold temperature control device (S602). The mold temperature controller receives the stop signal,
The mold temperature controller stops the mold temperature control. next,
While monitoring the operation signal of the casting machine 1, it is determined whether or not the stop signal is turned off (S603). Turning off the stop signal means that the operation of the casting machine has been restored. When the operation of the casting machine is restored (S603: Yes), a re-operation signal is sent to the mold temperature control device (S60).
4) Restart the temperature control of the mold and end the program. During execution of the trigger program shown in FIG. 5, it is assumed that the trigger flag TRG is set,
Since the flag is not set, the process for the mold temperature control device is not performed, and the process proceeds to the next step.

In the next task routine, a child program corresponding to TASK = 4 is executed. In the case of the execution program shown in FIG. 10, the child program corresponding to TASK = 4 is a data collection program, which is executed. The data collection program receives communication from the peripheral devices 2A to 2M, time-series sensor input from devices connected to the system management computer 4, and data processed in the peripheral device, and stores them in the common data area of the RAM 5. For the purpose. The contents of the data collection program are shown in FIG. 7, and the following processing is performed.

The data collected by executing the data collection program includes the injection speed of the die casting machine 1, the casting pressure, the gas pressure in the cavity, and the stroke when a local piston is separately applied to the local portion of the cavity by a piston. included. These data can be obtained from various sensors attached to the die casting machine 1, but usually require data for several seconds from injection to filling of the molten metal. When the data collection program starts, the start address of the common data area is received from the main program,
The data stored in the common data area can be read or written during execution of the data collection program (S701). The same processing as in S501 is performed. Next, a data request signal is transmitted, and data to be collected is input in time series (S702). The input data is stored in the common data area of the RAM 5 (S70).
3) A routine flag indicating the completion of data collection is set (S704), and the program ends.

In the next task routine, a child program corresponding to TASK = 5 is executed. In the case of the execution program shown in FIG. 10, the child program corresponding to TASK = 5 is a data processing program, which is executed. The data processing program is executed by a peripheral device or a system management computer 4.
This is a program for processing and processing the time-series data collected from the devices connected to the RAM 5 and storing the results in a common data area of the RAM 5, and is not hardware-dependent. The contents of the data processing program are shown in FIG. 8, and the following processing is performed.

When the data processing program starts,
The head address of the common data area is received from the main program (S801). Next, data processing is performed (S802). Necessary data is read from the common data area, and in the present embodiment, necessary data such as the temperature at the time of injection of the mold temperature, the maximum temperature, the minimum temperature, and the like are obtained. Then, a flag indicating that the data processing has been completed is set (S80).
3) End the program.

In the next task routine, a child program corresponding to TASK = 6 is executed. In the case of the execution program shown in FIG. 10, the child program corresponding to TASK = 6 is a data comparison program, which is executed. The data comparison program is a program for mainly performing a pass / fail judgment, comparing preset data and measured data, and storing the judgment result in a common data area of the RAM 5. The contents of the data comparison program are shown in FIG. 9 and the following processing is performed.

When the data comparison program starts,
Set the address of the data in the common data area,
The data stored in the common data area can be read during execution of the data comparison program (S901).
Then, the set values such as the target value, the upper limit value, and the lower limit value of the mold temperature set by the system management computer 4 and the measured values obtained by executing the data processing program shown in FIG. Is performed (S902). The result of the comparison process is written in the common data area of the RAM 5, and the program ends.

Hereinafter, similarly, TASK = 7, TASK = 8 and TASK = 8
The child program corresponding to SK = 9 is executed. In the case of the execution program shown in FIG. 10, the child program corresponding to TASK = 7 is an alarm output program. As a result of executing the data comparison program, for example, when the lower limit of the mold temperature is lower than the set value, Raise an alarm. Based on the alert,
Processing such as moving the product to the defective tray or marking the product is performed. The child program corresponding to TASK = 8 is a data storage program, and performs processing for storing one cycle of data on a hard disk, a floppy disk, or the like. The child program corresponding to TASK = 9 is a screen display program, and performs processing for displaying processing data, data comparison results, and the like.

As described above, there are two types of child programs, those directly related to hardware and those that only perform data processing, from the processing contents. The former is prepared corresponding to each hardware (peripheral device, interface between the peripheral device and the system management computer 4). The latter is supplied according to the hardware control method. As a child program independent of hardware, in addition to the above, a control program that converts input data collected from peripheral devices and devices connected to a system management computer into a control output according to a predetermined algorithm and stores it in a predetermined memory There are an output operation program, a data storage program for storing a data group in a previously specified area in a specified storage medium in a specified format, and a composite program having a plurality of functions of these programs.
When a compound program is more efficient due to the problem of time lag caused by dividing the functions of multiple programs and due to the nature of peripheral devices, the processing is fixed and the possibility of change is low. Used in some cases.

[0037]

As described above, according to the present invention,
The processes in the casting process control routine are all divided into child programs for each device and function, and the user can freely design the processes in the routine by selecting a prepared child program. Therefore, it is easy to cope with different management methods depending on products, and it is possible to realize overall management of the casting process. The dependence of the main program on the hardware (device) is low, and the child programs are divided according to functions, so that it is possible to easily respond to hardware upgrades and partially improve software.

Further, in the present invention, the control of the die casting machine and the peripheral devices is comprehensively managed by using an independent system management computer, and individual processing or highly relevant processing in a routine work repeated for each casting cycle is performed. The summary is a child program independent of the main program. Since all processes related to hardware (peripheral devices and interfaces between the peripheral devices and the computer) are independent of the main body program and are supplied as child programs corresponding to the respective peripheral devices, the user can select and execute these child programs in the order of execution. By setting, it is possible to cope with rearrangement of peripheral devices that differ depending on factories and products, and it is possible to easily perform overall management of the casting process. Therefore, it is possible to simplify the conventional checking operation. For example, when an error occurs and the casting machine stops, a method for communicating to workers, a method for storing data when an error occurs, a method for marking products when an error occurs, and a control signal to peripheral devices when an error occurs The hardware and specifications to be used differ depending on the factory or product, such as the transmission of data. Since the software (child programs) for controlling the hardware is separated for each function, the user can freely design the casting process control routine by combining the child programs. Further, the control flow in the routine can realize control corresponding to a situation change such as a trouble by the presence of a control flag (common data area) accessible from each of the main program and the child program.

In the present invention, since all processes relating to the hardware (peripheral devices and the like) are independent of the main program, when upgrading the hardware or adding a new peripheral device to the process, the child process is modified. Or
It can be dealt with simply by adding it, and its resources can be used without changing the main program.

Further, in the present invention, since the control theory (software) corresponding to each peripheral device is supplied as a child program independent of hardware, the control theory can be upgraded only by updating the child program. However,
If it is better to have a control function independently among peripheral devices (so that manual operation can be performed when the system management computer fails), incorporate a control function into the peripheral device.
Only the input data and the control result are stored in the common data area.

Since the child program has a common data area which can be accessed mutually, input data obtained by the function of each peripheral device can be used for controlling other peripheral devices.
