Field of the Invention The present invention has an operation switch capable of selecting and specifying an object to be controlled and its control contents, and operating the operation switch to input an operation signal through a programmable controller (PC). The present invention relates to a running operation control device for equipment capable of executing a predetermined sequence control for a corresponding control target.

[0002]

2. Description of the Related Art Conventionally, a programmable controller (P
C) or FA controlled in sequence by a relay circuit
Chemical conversion equipment is known. Then, in the equipment adjustment stage, there is a step of performing a running operation for each function unit or each device unit constituting the function to confirm and guarantee each function. When performing this running operation, it is necessary to repeatedly operate each operation button of the operation panel for the required number of times of running.

[0003] For example, when it is desired to advance and retreat the loader 20 times, the loader is first advanced by pressing a button for instructing the loader to advance. Then, after confirming that the vehicle has moved forward to the predetermined position, the user presses a button for instructing retraction of the loader, and retreats the loader. After confirming that the loader has retreated to its original position, press the loader advance button again. In this manner, the running operation was performed by repeating the same operation 20 times.

[0004]

However, it is necessary for a worker to press the button every time during a running operation to give an instruction. The more the number of times of the running operation, the more labor is required and the lower the work efficiency. Will be. On the other hand, when creating a program in advance,
It is known that a running operation circuit considered to be necessary is incorporated, a program for executing the running operation is created, and a running operation program is called by an operation of an operation panel and executed.

[0005] According to this method, the number of operations that must be performed by the operator during the actual running operation can be reduced.
Creating a running operation execution program in the design stage of the control circuit in advance causes an increase in design time, and it may not be possible to incorporate the program depending on the program capacity.

[0006] Furthermore, only a running operation can be performed by a pre-registered running program, and it is impossible for an operator to freely set a running pattern.
Therefore, a desired running operation may not be performed. Therefore, the present invention has an object to solve the above-mentioned problems. In particular, even a general worker who does not have specialized knowledge can easily construct and execute a desired running operation sequence, and furthermore, the operation work can be simplified. It is an object of the present invention to provide a running operation control device for equipment which can be operated at a high speed.

[0007]

In order to achieve the above object, the present invention has the following structure as means for solving the problems. That is, as illustrated in FIG. 1, there is provided an operation switch capable of selecting and specifying a control target and its control content,
Switching between a running operation sequence registration mode and a running operation execution mode in equipment capable of executing a predetermined sequence control for a corresponding control target via a programmable controller (PC) by an operation signal input by operating the operation switch. A possible changeover switch,
And steerable operation completion instruction means an operation completion, when the operation signal is inputted in the registration mode, before the control object is actuated, leave temporarily storing I / O status data of the PC, Operation completed by the above operation completion instruction means
Is instructed, the I / O state data at the time of completion of the operation is compared with the pre-operation data to extract changed data, and the changed data is stored at the time of completion of the operation corresponding to the operation signal. Operation completion data storage means for storing as data, and the order of the operation signal input in the registration mode state, and running data consisting of the input number of times of running are stored in association with a predetermined registration number. When the registration number is designated in the running mode state, the operation signal is read out in accordance with the order stored in the running data storage means, output to the PC, and activated by the operation signal. The I / O status data corresponding to the control target to be
If the input I / O state data matches the I / O state data at the time of completion of the operation, the next operation signal is output, whereby the running data storage means is output. Running operation control means for repeatedly executing a series of running operations corresponding to a series of operation signals stored in the storage device for the stored number of times of running. This is the gist.

[0008]

According to the running operation control apparatus of the present invention having the above-mentioned configuration, first, the operation mode is set to the registration mode, and the operation switch is operated so that the desired control target and the control contents are changed according to the operation order. I will enter as. that time,
Each time the operation completion registration means receives one operation signal,
The I / O status data of the PC before the corresponding control target is activated is temporarily stored, and the operation completion instructing means is used.
When the operation completion is instructed, the I / O state data at the time of completion of the operation is compared with the pre-operation data to extract changed data, and the changed data is used when the operation corresponding to the operation signal is completed. Is stored as data.

On the other hand, the order / count registering means stores the order of the operation signals input in the registration mode state and the number of runnings input by, for example, a numeric keypad in association with a predetermined registration number. When the registration is completed, the state is set to the execution mode state and the registration number is designated. When the registration number is designated, the running operation control means reads out an operation signal in accordance with the order stored in the order / number registration means and outputs the operation signal to the PC. O status data is input, and the input I / O status data is
When the state data matches, a series of running operations corresponding to a series of operation signals stored in the order / number registration means are stored while outputting the next order of operation signals. Run repeatedly for the number of runs.

[0010] Therefore, when registering the running operation sequence, the operator operates the operation switch to input a desired control target and its control contents in accordance with the operation order.
Then, it is only necessary to instruct the completion of the operation via the operation completion instructing means. In order to execute the running operation, it is sufficient to simply specify the registration number first.

In addition, it is not necessary to incorporate a running circuit in the control circuit design stage in advance, which increases the design time,
And increase in the amount of programs is prevented. Furthermore, while the free running operation sequence can be set, the setting operation is simple as described above, and does not require specialized programming knowledge. Thus, in particular in no general operator expertise can Rukoto to build and run easily desired running operation sequence.

The control target section 1 is composed of a loading section, a component supply section, a processing section, an unloading section, and the like. FIG. 3 schematically shows the configuration of the loading unit. The loader 11 is advanced / retracted by a pneumatic cylinder (not shown), and position confirmation sensors LS1 and LS2 are provided at predetermined advance and retreat positions for confirming the operation position of the loader 11, respectively. I have. On / off signals from the position confirmation sensors LS1 and LS2 are transmitted to an input / output interface module (not shown) of the PC 3 (not shown).
It is called an / O module. ). In addition, as the operation of the loading section, in addition to the forward / backward movement of the loader, there are ascending / descending, chucking / unchucking of the work W placed on the work table 13, and the like.

Next, the operation panel 5 will be described. Operation panel 5
Is provided with a display unit 21 using a liquid crystal display, a numeric keypad 23 for inputting numbers, and the like, and is connected to a control unit 25 described later. A transparent touch key panel (hereinafter, referred to as a touch key) 27 is mounted on the display unit 21, and the touch key 27 is used instead of a mechanical operation button switch.

The control unit 25 of the operation panel 5 includes a CPU 2
5a and a memory 25b.
Display interface 2 for outputting display signals to
5c, a touch key interface 25 provided for inputting signals from the touch keys 27 and the ten keys 23
d, a ten-key interface 25e, an external registration device 50 described later, an external device interface 25f for mutually inputting / outputting with the PC 3, and a PC interface 25g are alternately connected via an address data bus 25h. .

The display unit 21 is divided into an appropriate number of push buttons (six in this embodiment), each of which can display an operation name composed of a combination of a control target and its control content. This operation name is registered in the memory 25b in advance. For example, as the operation name for the loading unit, as shown in FIG.
The configuration is such that six types of “up / down” and “chuck / unchuck” are respectively displayed on the display screen.

Further, the display unit 21 has the display shown in FIGS.
5C, a registration / execution selection screen P1, an individual operation screen P2, a procedure registration confirmation screen P3, and FIG.
A registration number selection screen P4 shown in (b) and (c), respectively.
The screen P5 during the running operation can be displayed.
Each of these screens P1 to P5 will be described later in detail.

Then, by pressing the vicinity of the displayed switch name from above the touch key 27, the control unit 25 can determine which button has been selected. An operation signal corresponding to the selected operation name is output from PC interface 25g to PC3. When the operation signal is input, the PC 3 performs sequence control on a control target corresponding to the operation signal in accordance with a predetermined sequence program, and executes operation steps. Of course, the operation steps are interlocked so as not to interfere with each other.

The display section 21 is not limited to a liquid crystal display, but may use other display means such as a CRT display. The touch keys 27 may be mechanical operation button switches. The numeric keypad 23 can be replaced by a digital switch.

Next, the operation of the present embodiment will be described by taking as an example a case where the loader 11 is repeatedly run forward and backward to perform a running operation. First, the operation procedure of the operator when registering the running operation sequence and the operation of the running operation control device will be described with reference to the flowcharts of FIGS.

First, the control target unit 1 is set in a state where it can be operated individually. Then, the operator changes the screen of the display unit 21 to the registration / execution selection screen P of the running operation shown in FIG.
The registration mode is set by pressing the part displayed as "Registration" from the touch key 27.

In the registration mode, the control unit 2
At 5, the registration order N is set to 1 (Step 100, hereinafter simply referred to as S100, the same applies hereinafter), and the process waits until each individual operation button is pressed (S110). The operator selects the individual operation screen P2 according to the control target to perform the running operation. FIG. 4B shows an operation screen P2 in the case of a loader unit. To perform a running operation in which the loader 11 repeats forward / backward movement, the “loader forward” button is first pressed.

Then, the control section 25 refers to the individual operation completion registration table T1 shown in FIG. 9 and determines whether operation completion data corresponding to the pressed operation button has been created (S120). If it has not been created (S120: NO), all I / Os of the PC 3 before the operation are performed.
After the state data is temporarily stored in the memory 25b (S13
0), an operation signal corresponding to the pressed operation button is transmitted to PC3.
(S140). On the other hand, when the operation completion data has been created (S120: YES), the process of S130 is skipped and the process proceeds to S140.

The PC 3 to which the operation signal has been input performs sequence control on the control target corresponding to the operation signal according to a predetermined sequence program, and executes the operation steps. In this case, since the “loader advance” button has been pressed, the loader 11 is advanced and stopped at a predetermined advance position.

At this time, a procedure registration confirmation screen P3 shown in FIG. 4C is displayed on the display unit 21.
When it is confirmed that the loader 11 has moved to the predetermined forward position, the operation completion confirmation button is pressed. Control unit 25
Determines that the operation completion confirmation button has been pressed (S1).
50: YES), referring to the individual operation completion registration table T1, it is determined whether or not the operation completion data corresponding to the pressed operation button has been created (S160). In this case, since it has not been created (S160: NO), the PC
3 is temporarily stored in the memory 25b (S170).

Then, all the I / O state data (O / O) of the PC 3 before and after the operation temporarily stored in the memory 25b.
(N or OFF), the changed I / O state data is extracted, and the I / O state data after the operation is registered as operation completion data in the individual operation completion registration table T1 (S180). Further, the pressed operation button is registered in the N-th (in this case, the first) of the running order registration table T2 corresponding to the registration number 1 (S190).

For example, when the loader advances, the input from the forward position detecting sensor LS1 is "OFF" and the retracting position detecting sensor LS2 is "ON" before the forward operation of the loader 11. It is. When the vehicle is stopped at a predetermined forward position under the control of the PC 3, the position confirmation sensor LS1 at the forward position is "ON" and the position confirmation sensor LS2 at the backward position is "OFF". Therefore, the data after the operation of the changed I / O state data, that is, LS1 is “ON”, LS2
Registers "OFF" in the individual operation completion registration table T1 as operation completion data.

On the other hand, if the operation completion data has been created in S160, the processing in S170 and S180 is skipped, and the flow proceeds to the processing in S190. When the process of S190 ends, the registration order N is incremented (S200). And
It is determined whether the procedure registration completion button shown on the procedure registration confirmation screen P3 in FIG. 4C has been pressed (S210). If not, it is determined whether the procedure registration continuation button has been pressed (S220). .

In this case, the operator wants to register the retraction of the loader 11 next, and presses the procedure registration continuation button. When this procedure registration continue button is pressed (S220: YE
S), the individual operation screen P2 is displayed again on the display screen 21, and the process returns to S110 to wait for the operation button to be pressed (S110).

Then, when the "loader retreat" button is pressed (S110: YES), it is determined whether or not the corresponding operation completion data has been created, as in the case of the "loader advance" button described above (S120). If not created, all I / O status data of PC 3 before operation is stored in memory 25b.
(S130). Thereafter, an operation signal is output to the PC 3 (S140), and the loader 11 is retracted,
Stop at a predetermined retreat position.

When the operator confirms that the loader 11 has moved to the predetermined retreat position, the operator presses the operation completion confirmation button. When the operation completion confirmation button is pressed (S150: YES), the control unit 25 determines whether or not operation completion data has been created by referring to the individual operation completion registration table T1 (S160). Not so
All the I / O state data of the PC 3 after the operation is temporarily stored in the memory 25b (S170).

Then, all I / Os of the PC 3 before and after the operation are performed.
The O state data is compared, and the operated I / O state data of the changed I / O state data is registered in the individual operation completion registration table T1 as operation completion data for "loader retreat" (S180). Further, the "loader retreat" operation button is registered in the Nth (in this case, the second) in the running order registration table T2 (S190).

[0033] After this, when the procedure completion of the registration button is pressed, (in the case of this registration rank third) running order of the registration table T2 (N + 1) th writes "END" to. Then, when the operator inputs the number of running times from the numeric keypad 23, the control unit 25 registers the input number of running times (in this case, 20 times) in the running order registration table T2, and once ends the main registration process.

The running operation for moving the loader 11 forward / backward is registered in the running order registration table T2 of the registration number 1; however, other running operations, for example, ascent / descent of the loader 11, or loader 11 It is possible to register the operation in the desired running order, which is an arbitrary combination of six types of operations of 11 "forward / backward", "up / down", and "chuck / unchuck", corresponding to each registration number. It is.

The above-mentioned operation is performed by the external registration device 50.
, And via the external device interface 25f,
The individual operation completion registration table T1 and the running order registration table T2 in the memory 25b can be registered. At this time, the index name of the registration number selection screen P4 is created and registered by the external registration device 50.

Next, the operation for executing the running operation will be described with reference to the flowchart of FIG. First, the control target unit 1 is set in a state in which each unit can be operated. Then, the operator sets the screen of the display unit 21 to the registration / execution selection screen P1 shown in FIG. 5A, and presses a portion displayed as “execute” from the touch key 27 to enter the execution mode state. Then, a registration number selection screen P4 shown in FIG. 5B is displayed. The operator selects a registration number to be executed on the registration number selection screen P4, and presses the execution button after the selection. When this execution button is pressed on the registration number selection screen P4, the running operation execution processing is started.

First, the control section 25 sets the reading registration order N = 1 and the running number counter C = 0 (S300). Then, among the running order registration tables T2 stored in the memory 25b, the N-th operation button (in this case, the first “loader advance”) registered from the table of the selected registration number is read, and
The corresponding operation signal is output to PC3 (S310).

The control unit 25 outputs the "loader advance" output to the PC 3 from the individual operation completion registration table T1.
Are extracted and temporarily stored (S320). On the other hand, PC3 to which the operation signal has been input
Sequence control is performed on the loader 11 in accordance with a predetermined sequence program to execute a forward operation step. When the loader 11 is advanced in this way, the control unit 25 fetches the corresponding I / O state data from the PC 3 (S330), and determines whether or not it matches the operation completion data corresponding to the above-mentioned “loader advance”. Is determined (S340), and the processes of S330 and S340 are repeated until they match.

When the loader 11 moves forward and stops at a predetermined forward position, and the I / O state data from the PC 3 matches the operation completion data (S340: YE
S), the read registration order N is incremented (S35).
0), it is determined whether it is the last step of the running (S3).
60). Whether or not this is the final step is determined by checking whether or not “END” is written at the position of the incremented registration order.

In this case, there is no “END” at the incremented registration order, that is, at the position of N = 2 (S36).
0: NO), unless the forced end button is pressed (S370: NO), return to S310 and repeat the following processing. With reference to the running order registration table T2,
The second operation button (loader retreat) registered is read, and the corresponding operation signal is output to PC3 (S31).
0), operation completion data corresponding to “loader retreat” output to the PC 3 is extracted from the individual operation completion registration table T1, and temporarily stored (S320).

When the PC 3 is executing the loader retreat operation step, the control unit 25 fetches the corresponding I / O state data from the PC 3 (S330).
It is determined whether the data matches the operation completion data corresponding to the above-mentioned “loader retreat” (S340).
Steps 330 and S340 are repeated.

When the loader 11 stops at the predetermined retreat position and the I / O state data from the PC 3 matches the operation completion data (S340: YES), the reading registration order N is incremented (S340: YES). (S350), it is determined whether or not it is the last step of the running (S360).

In this case, since “END” is written in the incremented registration order, that is, at the position of N = 3 (S360: YES), the running operation has been completed once, and the read registration order N = 1. The running number counter C is incremented (S380). This means that one running operation has been completed.

Then, it is determined whether or not the value of the counter C is equal to the number of running times (in this case, 20 times) registered in the running order registration table T2 (S390). Unless the end button is pressed (S370: NO), the process returns to S310 and repeats the following processing.

In this way, the "loader advance" and "loader retreat" are repeated, and when the value of the counter C incremented in S380 becomes C = 20, it is equal to the registered number of running times (S390: YE
S), the running operation execution process ends.

During the running operation, a running operation screen P5 shown in FIG. 5C is displayed, and the registration number and name of the running operation being executed and the current number of times of running are displayed. When the forced termination button is pressed during the running operation (S370: YE
S), the process is terminated without returning to S310.

The execution of the processing of the memory 25b, particularly, the individual operation completion registration tables T1 and S110 to S180 functions as operation completion data storage means, and the memory 25b, particularly the running order registration tables T2 and S190 to S230.
Execution of the processing of (1) works as running data storage means.
The execution of the running operation execution processing shown in FIG. 8 functions as running operation control means.

As described above, according to the present running control apparatus, first, the apparatus is set to the registration mode, and a desired control object and its control contents are input as operation signals according to the order of operation. At that time, every time one operation signal is input, the I / O of the PC 3 before the corresponding control target operates.
The state data is temporarily stored, and when the controlled object completes the operation in response to the operation signal, the I / O state data at the time of the operation completion is compared with the pre-operation data to extract changed data. The changed data is stored in the individual operation completion registration table T1 as operation completion data corresponding to the operation signal.

On the other hand, the order of the operation signals input in the registration mode state and the number of runnings input by the ten keys 21 are stored in the running order registration table T2 in correspondence with a predetermined registration number. When the registration is completed, the state is set to the execution mode, the registration number is designated, and the execution button is pressed. Then, the running order registration table T
2 reads out the operation signals in the order stored in PC 2
3 to operate the control target and input I / O state data from the PC 3, and when the input I / O state data matches the I / O state data at the time of completion of the operation, the next While outputting the operation signal of the order, a series of running operations stored in the running order registration table T2 are repeatedly executed by the registered number of times of running.

Therefore, when registering the running operation sequence, the operator only has to operate the desired operation buttons on the individual operation screen P2 and input in order according to the desired running operation. When the running operation is performed, it is sufficient to simply specify the registration number first.

Further, it is not necessary to incorporate a running operation circuit in the design stage of the control circuit in advance.
And increase in the amount of programs is prevented. Furthermore, while the free running operation sequence can be set, the setting operation is simple as described above, and does not require specialized programming knowledge. Therefore, even a general worker having no special knowledge can easily construct and execute a desired running operation sequence.

As described above, the present invention is not limited to such embodiments at all, and can be implemented in various modes without departing from the gist of the present invention.

[0053]

As described in detail above, according to the running operation control apparatus of the present invention, when registering the running operation sequence, the operator operates the operation switch to control the desired control target and its control. Enter the contents according to the order of operation
Then, it is only necessary to instruct the completion of the operation via the operation completion instructing means. In order to execute the running operation, it is sufficient to simply specify the registration number first.

Also, it is not necessary to incorporate a running operation circuit in the control circuit design stage in advance, which increases the design time,
And increase in the amount of programs is prevented. Furthermore, while the free running operation sequence can be set, the setting operation is simple as described above, and does not require specialized programming knowledge. Thus, in particular in no general operator expertise, an effect that it is Rukoto easily be executed to build the desired running operation sequence.
