BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abnormality handling support device that allows an operator to quickly and accurately release an interlock when the device cannot be started due to an interlock.

0002

2. Description of the Related Art With the recent progress in automation technology, automobile production factories and the like are being automated using various automatic assembly devices, robots, and the like.

[0003] In general, in such automated equipment (hereinafter referred to as automatic equipment), in order to ensure accurate operation, to prevent interference with movable parts of adjacent equipment,
For the purpose of safety for operators and workers, a so-called interlock is applied to the control so that the automatic machine will not operate unless certain conditions are met.

For example, there is a conventional screw tightening device as shown in FIG. 6, so interlocking will be explained using this as an example. The illustrated screw tightening device is configured such that after positioning a workpiece 2 conveyed by a conveyor 1 using a positioning device 3, screws are attached to the workpiece 2 by a screw tightening machine 4. The operation of the device 3 and the screw tightening machine 4 is controlled by a control device 5.

The control device 5 includes a sensor A that detects that the work 2 has been transported to the positioning position of the positioning device 3, and a sensor B that detects that the positioning device 3 has positioned the work 2. , a sensor C that detects that the positioning device 3 has released the work 2, a sensor D that detects that the screw tightening machine 4 has descended and finished the screw tightening operation, and a sensor C that detects that the screw tightening machine 4 has moved up and finished the screw tightening operation. A sensor E is connected to detect the completion of the operation, and these sensors make it possible to recognize the operating state of the screw tightening device main body 6 consisting of the conveyor 1, positioning device 3, and screw tightening machine 4. ing.

Furthermore, an operation switch unit 15 in which various operation switches 10 to 14 are arranged is connected to the control device 5, and when the operator operates these switches, the control device 5 can be operated, for example. The operation of the screw tightening device main body 6 is controlled as follows.

[0007] The operator turns on the power switch 10 shown in the figure.
Then, change the changeover switch 11 to automatic, and turn the start switch 1
2 (hereinafter referred to as initial setting), the control device 5 operates the conveyor 1 to convey the workpiece 2 on the condition that the sensors C and E are turned on. (hereinafter referred to as work loading operation). Further, when the sensor A is turned on, the control device 5 operates the positioning device 3 to position the workpiece 2 (hereinafter referred to as positioning operation). When the positioning device 3 positions the workpiece 2 and the sensor B turns on, the control device 5 controls the screw tightening machine 4 until the sensor D turns on.
to tighten the screws to workpiece 2 by lowering the
The following is called screw tightening operation. ). Next, the control device 5
When the sensor D turns on, the screw tightening device 4 is raised and released from the workpiece 2 until the sensor E is turned on (hereinafter referred to as escape operation). Furthermore, the control device 5
When it is determined that the escape operation is completed by turning on sensor E, the positioning device 3 is operated to release the work 2 (hereinafter referred to as work release operation), and sensor A is turned off. By operating the conveyor 1 until then, the workpiece 2 is carried out (hereinafter referred to as the workpiece carrying-out operation).

The control device 5 that performs such operation control is provided with interlocks as shown in FIG. 7, for example, corresponding to each operation. As shown in the figure, when the operation shifts from the initial setting to the work loading operation, the power switch 10 is turned on, the changeover switch 11 is set to automatic,
The operation of the screw tightening device main body 6 does not proceed to the next workpiece loading operation unless the condition (2) in which the start switch 12 is turned on and the sensors C and E are turned on is met. In other words, the condition (2) is an interlock, and if this does not hold true if an abnormality occurs in the operation of the operation switch (for example, when the changeover switch is not switched automatically) or an abnormality occurs in the screw tightening device main body 6 (for example, the positioning device 3 or screw tightening machine 4 is out of order and sensor C or sensor E is not ON), the conveyor 1 does not operate without proceeding to the next workpiece loading operation.

As shown in the drawings below, in order to shift from the workpiece loading operation to the workpiece positioning operation, the sensor A is
The condition (■) for sensor B to turn on is the condition (■) for sensor B to turn on in order to transition from the workpiece positioning operation to the screw tightening operation, and the condition (■) for sensor D to be turned on to transition from the screw tightening operation to the escape operation. In order to shift from the escape operation to the workpiece release operation, the condition (■) for which sensor E turns on is the transition from the workpiece release operation to the workpiece release operation.
In order to shift to the workpiece unloading operation, the sensor C is ON, and in order to repeat the above operation, the sensor A is OFF to shift from the workpiece unloading operation to the workpiece loading operation.
The condition for F is set as an interlock.

[0010] Furthermore, by interlocking in this way, the control device 5 can operate the screw tightening device when the operation is stopped due to an abnormality in the screw tightening device main body 6 or when the emergency stop switch 14 is turned on. When the operation of the main body 6 is brought to an emergency stop, the control device 5
After the operator has dealt with such an abnormality, the screw tightening device main body 6 is controlled to be restarted.

At the time of restarting, the operator turns on the reset switch 13 to cancel the stoppage of operation, and then moves the selector switch 11 to manual and performs appropriate processing for the abnormality by manual operation or the like. and then
By setting the changeover switch 11 to automatic and turning on the startup switch 12, the control device 5 restarts the screw tightening device main body 6. That is, in the event of an abnormality, for example, as shown in FIG. 8, the reset switch 13
The counter C1 that remembers that the changeover switch 11 has been turned on turns on, the counter C2 that remembers that the changeover switch 11 has been set to manual is turned on, and the changeover switch 11 is set to automatic.
The condition (2) in which the start switch 12 is turned on is set as an interlock, and the control device 5 resumes automatic operation only when the operator performs the operations in the above order.

[0012] As described above, since conventional automatic machines and the like are controlled with interlocks corresponding to each operation, there is no possibility that the operator may make an erroneous operation or that an abnormality occurs in the machine. The system also automatically stops operating to prevent malfunctions.

[0013]

[Problems to be Solved by the Invention] However, in cases where such interlocks are complicated and incorporated, for example, there are many operating members that operate, and a large number of interlocks are required to prevent these operations from interfering with each other. In cases where an interlock is set, etc., when the device is automatically stopped due to an abnormality in the device as described above, it is possible to restart the device after dealing with the abnormality manually. If there are operating members whose interlocks have not been released even after this operation, that is, if each operating member is not in a state where it can be activated, the device will not be able to be activated.

Conventionally, the contents of the interlock are as follows:
In the above case, because it was written in the operation manual etc. that explained the operation contents and control contents,
The operator should carefully read the operation manual, understand the conditions under which the interlock will not be released (sensor input status, etc.), and set the appropriate interface based on this.
You will have to work to unlock it. Specifically, if the condition (2) shown in the initial settings in FIG. Have the child do the action.

[0015] Conventionally, when the device does not start even after the start-up operation is performed, the state of the interlocks is ascertained based on the operation manual, and if there is an interlock that has not been released, the operation is started. The work to release this was done based on the work procedure described in the manual, but in this way, the interface was not released based on the operation manual.
Ascertaining the lock status is extremely complicated as it requires searching for the appropriate interlock conditions depending on the equipment status, which can result in time-consuming equipment recovery, reduced productivity, etc. There was a problem.

[0016] Furthermore, if the operator is inexperienced or inexperienced, he or she may not be able to release the interlock based on the operation manual as described above, or it may be extremely difficult to do so. Conventionally, in order to speed up recovery, there has been a tendency to have as skilled a person as possible perform the operations, and as a result, the number of devices that can be operated by one operator is small. There were also problems such as the operator's work ability becoming lower.

[0017] The present invention has been made to solve these conventional problems, and allows the operator to quickly release the interlock when the device cannot be started due to the interlock. It is an object of the present invention to provide an abnormality handling support device that can handle errors accurately.

[0018]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an operating switch operated by an operator, an operating means for performing a predetermined operation set in advance according to the operating state of the operating switch, A detection means for detecting the operating state of the actuating means, and control for controlling the actuating means to perform a preset operation according to the operating state of the operation switch while checking the operating state of the actuating means based on the detecting means. An abnormality handling support device provided in a device having means,
Storage means for storing activation data indicating the operating state of the operating switch that is a condition for releasing the control interlock performed by the controlling means and the operating state of the operating means detected by the detecting means, and the operating switch that is input to the controlling means. and the current operating state, which is the operating state of the actuating means detected by the detection means, are sequentially stored in accordance with the operation of the operating switch and the operation of the actuating means to create operating state history data;
When a starting operation is performed to start the actuating means using the operating switch, the current operating state is compared with the operating state indicated by the starting data in the storage means, and if the respective operating states do not match, the interlock is released. an instruction content output means for outputting a preset instruction content to match the respective operating states based on the operating state history data when the instruction content is not matched; The invention is characterized in that it has a recognition means for recognizing the information.

[0019]

[Operation] The abnormality handling support device of the present invention configured as described above operates as follows. When the operator operates the operating switch, the control means operates the operating means in accordance with the operating state of the operating switch while confirming the operating state of the operating means using the detection means. At the same time, the instruction content output means inputs the operating state of the operating switch input to the control means and the current operating state that is the current operating state of the operating means detected by the detection means, and inputs the operating state of the operating switch and the operating state of the operating means detected by the detection means. The data is stored sequentially according to the operation to create operating state history data. Then, when the operator performs a starting operation to start the actuating means using the operation switch, for example, when turning on the starting switch, the instruction content output means outputs the current operating state last stored as operating state history data; In other words, the operating state of the operating switch and the operating means at the time of the starting operation is stored in the starting date stored in the storage means.
Compare with the operating status indicated by the data. As a result, if these operating states do not match, for example, if the operator makes a mistake in operating the operating switch or if the operating means is not in a state where it can be started, the instruction content output means will change the working state. Pre-set instruction contents to match each operating state based on history data, that is, instruction contents to make the operation switch operate normally or instructions to make the actuating means ready for activation. Output the content to the recognition means. The recognition means allows the operator to recognize the input instruction contents visually, audibly, or the like. Therefore, if the device does not start because the operator makes a mistake or the actuating means is not in a state where it can be started, the operator does not have to perform the troublesome work that is done in the past. The interlock can be released according to the instruction content recognized by the recognition means, and the device can be restarted quickly and reliably. In addition, since the recognition means allows the operator to understand the instructions for releasing the interlock, it is possible for the operator to quickly and easily release the interlock regardless of the level of experience. The operator can be an inexperienced person or an inexperienced person, and even if a single operator is operating many devices, it will be easier to understand when an abnormality occurs. Recovery will no longer be delayed as in the past.

FIG. 1 is a schematic configuration diagram of an abnormality handling support device of the present invention, and FIG. 2 is a diagram showing startup data stored in the storage device shown in FIG. 1. 3 and 4 are diagrams showing operation state history data stored in the memory of the instruction content output device shown in FIG. 1, and FIG. 5 is a diagram showing the operation flow of the abnormality handling support device of the present invention. It's a chart. In this embodiment, a case is illustrated in which the abnormality handling support device of the present invention is attached to the screw tightening device described in the conventional technology, but the abnormality handling support device of the present invention is not limited to this and can be applied to other so-called automatic Of course, it can be applied to machines. Further, since the illustrated screw tightening device has the same device configuration and operation as described in the related art, the description thereof will be omitted here.

As shown in FIG. 1, the abnormality handling support apparatus of the present invention includes a storage device 20 as the storage means, an instruction content output device 21 as the instruction content output means, a display device 22 as the recognition means, and It is composed of a speaker 23.

As shown in FIG. 2, the storage device 20 stores startup data corresponding to conditions for releasing the interlock when the screw tightening device main body 6 is started. This start-up data is stored in each switch of the operation switch unit 15 that satisfies the conditions shown in FIGS. This shows the operating state of the counter C2, which stores the fact that the changeover switch 11 is set to manual.

As the conditions for releasing the interlock when starting the screw tightening device main body 6, the conditions shown in FIG. 7 and FIG. The normal startup data corresponding to ■ and the abnormal recovery startup data corresponding to ■ are respectively data.
It is digitized and memorized. In addition, "0" in Figures 2 to 4
indicates an OFF state, and "1" indicates an ON state.

The storage device 20 also stores, for each switch, the contents of instructions to be given to the operator when the operator makes a mistake and performs an abnormal operation. Specifically, the storage device 20 includes a changeover switch 11.
"Please set the selector switch to automatic."
The contents of instructions for operating each switch, such as "Please set the changeover switch to manual" and "Please turn on the start switch" corresponding to the start switch 12, are converted into data and stored. has been done. For the counter C1, since the counter C1 remembers that the reset switch 13 has been turned on, the contents of the instruction such as "Please turn on the reset switch" are sent to the counter C1 in response to this.
Regarding 2, the counter C2 remembers that the changeover switch 11 was set to manual, so please set the changeover switch to manual once. After dealing with the following abnormality, set the changeover switch to automatic and turn on the start switch. Please.”
The contents of the instructions are stored in the storage device 20, respectively.

Furthermore, the storage device 20 stores the contents of instructions for performing work and operations for bringing the screw tightening device main body 6 into a startable state in correspondence with each sensor in the form of data. Specifically, the memory device 20 stores information such as "Sensor A is ON. Please remove the workpiece" for sensor A, and "Sensor B is ON for sensor B." Instructions such as "Please have the positioning device perform the operation to release the workpiece" or "Sensor D is ON. Please raise the screwdriver" in response to sensor D. is converted into data and stored.

Then, the contents of these instructions are displayed on the display device 22.
The instruction content output device 21 that controls output to the speaker 23 is equipped with an output control section 30 and a memory 31.

The output control section 30 records the operating states of each switch of the operation switch unit 15 input to the control device 5 and the counters C1 and C2 in the control device 5 every time one of the switches is turned on. The data is digitized and sequentially stored in the memory 31 as shown in FIG. 3 to create operation state history data of the operation switches.

The output control unit 30 also inputs the operating states of the sensors A to E via the control device 5, and similarly converts these into data each time one of the sensors A to E operates. As shown in FIG. 4, the data is sequentially stored in the memory 31 to create sensor operating state history data. In other words, the output control unit 30 controls the current operating states of the respective switches and sensors A to E of the operation switch unit 15 that are input to the control device 5, that is, the current operating states according to the operations of the respective switches and sensors A to E. By sequentially storing the data in the memory 31, the operating state history data is created in the memory 31.

When the start switch 12 of the operation switch unit 15 is turned on, the output control section 30 compares its current operating state with the start data in the storage device 20. The output control unit 30 determines whether the current time is normal startup or abnormal recovery startup depending on whether the counter C1 or C2 is ON. , the current operating state is stored in the storage device 20
The current operating state is compared with the operating state indicated by the normal startup data in the storage device 20, and if it is an abnormal recovery startup, the current operating state is compared with the operating state indicated by the abnormal recovery startup data in the storage device 20.

As a result, if the compared operating states do not match, the output control unit 30 determines that the interlock has not been released and cannot be activated, and stores the information in the memory 31. The content of the instruction for matching the current operating state to the operating state indicated by the activation data is read out from the storage device 20 based on the respective operating state history data, and is converted into an image signal and an audio signal and displayed. Device 2
2 and a speaker 23. In other words, if the compared operating states do not match, the output control unit 30 sends an instruction to the display device 22 and the speaker to make the compared operating states match, that is, to release the interlock. - It is designed to be output from the 23. Specifically, when the operating state of the operation switch among the current operating states does not match the operating state indicated by the startup data, the output control unit 30 stores the instruction content to make them match in the storage device 20. , and converts it into an image signal and an audio signal, which are output to the display device 22 and speaker 23. In addition, if the current operating state of the sensor does not match the operating state indicated by the startup data, the output control unit 30 outputs the instruction content to make them match as operating state history data. are read out from the storage device 20 in descending order of memory, converted into image signals and audio signals, and outputted to the display device 22 and speaker 23.

On the other hand, if the compared operating states match, the output control unit 30 determines that the operation performed by the operator is appropriate and that the screw tightening device main body 6 is ready to start, and issues an instruction. The content is not output. That is, when the starting switch 12 is turned on, the output control unit 30 compares the current operating state with the operating state indicated by the starting data in the storage device 20, and if the respective operating states do not match, the interlock is released. Only when this is not the case, a preset instruction to match the respective operating states based on the operating state history data is output to the display device 22 and the speaker 23.

The display device 22 is constructed of a so-called CRT or the like, and is adapted to display the above-mentioned instructions, such as characters, based on an input image signal. Further, the speaker 23 is adapted to output the instruction content in the form of voice based on the input voice signal.

The abnormality handling support device of the present invention configured as described above operates based on the flowchart shown in FIG. The output control unit 30 operates simultaneously with the operation of the control device 5 when the operator turns on the power switch 10 of the operation switch unit 15, and outputs an input to the control device 5 every time one of the operation switches is turned on. The operating states of all the operating switches of the operating switch unit 15 are converted into data and sequentially stored in the memory 31 to create operating state history data of the operating switches (steps 1 and 2).

Next, the output control unit 30 converts the operating states of all the sensors into data each time any one of the sensors A to E operates and sequentially stores the data in the memory 31. (steps 3 and 4).

Then, the output control section 30 repeats the above operation until the starting switch 12 of the operation switch unit 15 is turned on (step 5).
2 is turned on, the current operating state is compared with the operating state indicated by the corresponding startup data in the storage device 20 (step 6).
.

If the compared operating states match, the output control unit 30 proceeds to step 9; if they do not match, the output control unit 30 determines that the interlock has not been released (step 7). , the instructions corresponding to the switches and sensors that do not match are read out from the storage device 20 based on the respective operating state history data stored in the memory 31, converted into image signals and audio signals, and displayed. device 22
and output to the speaker 23. Then, the display device 22 displays the characters etc. of the instruction content based on the input image signal,
The speaker 23 outputs the instruction content based on the input audio signal as a voice (step 8).

The output control device 30 is connected to the screw tightening device main body 6.
The operations from step 1 to step 8 are repeated until one cycle of operation is completed, that is, until the operation from the initial setting to the workpiece unloading operation is completed (step 9).

Here, for example, the screw tightening device main body 6 stops due to an abnormal operation during the screw tightening operation, and the operator tries to recover from the abnormal stop, but turns on the reset switch 13 by mistake. Just press the start switch 12
The specific operation of this abnormality handling support device will be explained by taking as an example a case where the abnormality handling support device is turned on. In addition, the screw tightening device main body 6
It is assumed that normal initial settings have been made in advance, with sensors C and E turned on and sensor A turned off.

First, when the operator turns on the power switch 10 of the operation switch unit 15, the output control section 30 of the instruction content output device 21 changes the operating state of each operation switch as shown at A0 in FIG. It is stored in the memory 31 (steps 1 and 2).

[0040] The output control section 30 also controls the power switch 10.
Since sensors C and E turn on at the same time as , the operating states of the respective sensors are stored in B0 of the memory 31 as shown in FIG. 4 (steps 3 and 4).

At this point, the start switch 12 has not been turned on and one cycle of operation has not been completed, so the process returns to step 1 via steps 5 and 9.

Next, when the operator turns on the start switch 12, the output control section 30 stores the operating state of each operation switch in A1 of the memory 31 as shown in FIG. ).

[0043] At the time when the start switch 12 is turned on, none of the sensors has been activated yet, so the output control section 30 proceeds to step 6 via steps 3 and 5, and records the current operating state, that is, the memory. 31 A1 and B
The operating states of the operation switches and the respective sensors stored at 0 are compared with the operating states indicated by the normal startup data in the storage device 20 shown in FIG. 2 (step 6). At this point, the compared operating states match, so the output control unit 30
returns to step 1 via step 9 (step 7)
.

Furthermore, the output control section 30 performs step 3,
4 is repeated, and the operating states of the respective sensors are sequentially stored in the memory 31 according to the operation of the screw tightening device main body 6, as shown in B1 to B3 of FIG. Then, when the screw tightening device main body 6 stops due to an abnormal operation during the screw tightening operation, and the operator turns on the reset switch 13 to recover from the abnormal stop, the output control section 30 operates as shown in FIG. The operating status of each operation switch is stored in A2 of the memory 31.
(steps 3 and 4). At this time, counter C1
is also turned on, so remember this as well.

Next, when the operator turns on the start switch 12 by mistake, the output control section 30
As shown in FIG. 3, the operation state of each operation switch is stored in A3 of the memory 31 (steps 1 and 2).

Then, the output control section 30 proceeds to step 6, and determines the current operating state, that is, the operating state of each operation switch and each sensor stored in A3 and B3 of the memory 31, if there is an abnormality in the storage device 20 shown in FIG. It is compared with the operating state indicated by the recovery activation data (step 6).

As a result, the output control unit 30 first reads out the instruction contents corresponding to the counter C2 that do not match from the storage device 20 in order to make the compared operating states match. , converts this into an image signal and an audio signal and sends it to the display device 22 and speaker 23.
Output to. Further, the output control unit 30 sorts the instruction contents corresponding to the sensors A, B, and D that do not match in the order of shallowness in memory as the sensor operating state history data in FIG. The instruction content, the instruction content corresponding to sensor B, and the instruction content corresponding to sensor A are read out from the storage device 20 in this order, and these are converted into image signals and audio signals and sequentially output to the display device 22 and the speaker 23. .

Then, the display device 22 and the speaker 23 sequentially display messages based on the input image signal and audio signal saying, ``Please set the changeover switch to manual once. After dealing with the following abnormality, set the changeover switch to automatic.'' and turn the start switch to O.
Please N. Sensor D is ON. Raise the screw driver. Sensor B is ON. Make the positioning device perform the operation to release the work. Sensor A is ON. Please remove the work. " is output in text and voice (steps 7 and 8).

Therefore, the operator can restart the screw tightening device main body 6 by following the above instructions outputted from the display device 22 and the speaker 23.

[0050] In this way, the output control unit 30 compares the current operating state and the operating state indicated by the start-up data, and if these operating states do not match, makes the respective operating states match. The display device 22 displays preset instruction contents such as
Since the operator is made aware of this by the speaker 23, if the operator makes a mistake in the operation or the screw tightening device main body 6 is not in a state where it can be started, and it does not start, the operator does not have to worry about the hassles of the conventional method. The interlock can be released according to the instructions recognized by the display device 22 and the speaker 23 without having to do any additional work.
The device can be started up quickly and reliably, and the screw tightening device can be quickly restored.

In addition, the display device 22 and the speaker 23 allow the operator to understand the instructions for the work of releasing the interlock, and the operator can easily understand the interlock regardless of his or her level of experience. Since the work to release the lock can be quickly and accurately grasped, one person can operate multiple devices regardless of the operator's experience, and the work ability of the operator can be improved. become.

[0052] In this embodiment, an example is given in which the operator is made to recognize the operation instruction to release the interlock for starting the screw tightening device main body 6 during automatic operation, but the invention is not limited to this. When the respective devices of the tightening device main body 6, that is, the conveyor 1, the positioning device 3, and the screw tightening machine 4, are interlocked during manual operation, the operator instructs the operator to release these interlocks. Of course, it is also possible to make the user recognize the information. Further, the means for making the operator aware of the instruction contents are not limited to the display device 22 and the speaker 23, but it is also possible to make the operator recognize the contents visually, audibly, etc. Of course, it's fine if it's something.

[0053]

[Effects of the Invention] As is clear from the above explanation, the present invention has the following effects. The instruction content output means compares the current operating state with the operating state indicated by the startup data,
If these operating states do not match, the recognition means makes the operator recognize a preset instruction to match each operating state based on the operating state history data. If the device does not start due to a mistake in operation or the activation means is not in a state where it can be activated, the system can be used to perform an interface operation according to the instructions recognized by the recognition means, without having to perform the complicated work required in the past. -By performing the work of releasing the lock, the device can be started up quickly and reliably, and the device can be restored quickly.

[0054] Furthermore, since the recognition means allows the operator to understand the instructions for the work of releasing the interlock, one person can operate a large number of devices regardless of the operator's experience. This makes it possible to improve the operator's work ability.
