Abstract

PURPOSE:To shorten the system stop time by constituting a system so that the condition of each device is automatically informed through a telephone line at the time of the stop of the automatic operation system. CONSTITUTION:Device such a such as a working machine 1a and a robot 1b constituting an automatic operation system 1, a vision sensor if, and an automatic informing device 3 are coupled with signal lines, and the condition of each device is sent from a control board 10 to the automatic report device 3. If the system 1 is stopped by some cause, for example, earthquake detection of an earthquake detector 1e, the state at this time is automatically transmitted to a reception equipment. A reception equipment 3b in the division in charge of maintenance confirms reception by a reception confirmation control panel 2a, and the equipment 3b individually restarts each device by a restart control panel 2b to finally restart the whole of the system if necessary. Thus, a monitor for the automatic operation system is unnecessary and the system stop time is shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic failure reporting system when a failure occurs in an automatic driving system such as an industrial robot system.

[Conventional technology]

When an automatic driving system malfunctions and stops, it is common for an operator or supervisor who is familiar with the automatic driving system to check the status of each device in detail and request repair from the maintenance department.

In addition, recent robot systems are increasingly operating 24 hours a day, and especially at night, there are only patrol monitors who are not familiar with robot systems.
In this case, if the robot stops for some reason, the maintenance service contractor is contacted to the effect that it has stopped anyway, so come and fix it. Since maintenance service providers differ in the parts, instruments, etc. they buy and bring with them depending on the outage situation, in the case of the above-mentioned contact, a person with general knowledge will be dispatched to conduct an on-site investigation, and the results will determine the quality and quality of the person who can respond. This creates a double burden of determining and re-arranging the parts, instruments, etc. to be brought, which is not only inefficient for the maintenance service provider but also results in longer downtime for the user, which is a disadvantage for both parties.

[Problem to be solved by the invention]

As mentioned above, in conventional automated driving systems, 1) In order to investigate the status of a stopped system, personnel who are familiar with the system are required, and a series of investigations and notifications to the maintenance department are required. Downtime becomes longer.

2) It is difficult for the maintenance staff in general to obtain accurate and sufficient information, so a person who understands the entire system is dispatched, and the appropriate personnel and parts, instruments, etc. are re-arranged. There was a problem that the stoppage time became long.

Therefore, this invention has been made in view of the above points, and its first object is to provide a failure reporting device for an automatic driving system that can quickly report the situation when the automatic driving system stops. .

A second object of the present invention is to provide a failure notification device for an automatic driving system that can quickly restart the system when the system is stopped.

[Means to solve the problem]

In order to achieve the first object, the present invention is equipped with an automatic reporting system that reports the status of each device of the automatic driving system via a telephone line when the automatic driving system according to the present invention stops.

In addition, in order to achieve the above-mentioned second objective, in the failure reporting system for an automatic driving system according to the present invention, the maintenance department is provided with a restart control system to control the restart of the stopped automatic driving system via a telephone line. It is equipped with a starting operation panel.

[Effect]

In the first invention, when the automatic driving system malfunctions and stops, the automatic notification system is activated and automatically reports the status of each device to the maintenance department via the telephone line.

Further, in the second invention, the control panel of the automatic driving system is controlled to restart via a telephone line by a restart operation panel provided between the maintenance departments.

〔Example〕

Hereinafter, an embodiment according to the first and second inventions will be described based on the drawings. In the embodiment shown in FIG. 1, (1) is a processing machine (la), a robot (lb), a hand (lc), a reception confirmation operation panel (2a), and a restart operation panel (2a) for the automatic operation system (1). 2b) and a work supply device (1d), etc., and controls the above-mentioned devices to stop when an earthquake is detected by an earthquake detector (1e). In addition, (i
f) is a vision sensor that monitors each device. Also,
(2) is the department in charge of maintenance, (3) is the automatic notification device (3a) provided on the automatic driving system side, the receiving device (3b) provided on the department in charge of maintenance side, and the automatic notification device and the receiving device are combined. This is an automatic reporting system consisting of telephone lines (3C). In addition, the control panel of the automatic driving system (1) (
IC) and the restart operation panel (2b) of the maintenance department (2) are also connected by a telephone line (3C).

In the above configuration, the automatic operation system (1) includes a processing machine (1a), a robot (lb), a hand (lc),
Each device such as the work supply device (1e), the vision sensor (1g), and the automatic notification device (3) are connected by signal lines, and the status of each device is automatically reported from the control panel (10) from time to time. If the automatic driving system (1) is stopped by the control panel (1e) for some reason, for example, when an earthquake is detected by the earthquake detector (1e), the situation at that time is automatically sent to the receiving device. (In addition, communication means such as telephone lines are to be used only when the automatic driving system is stopped.)

The contents of the automatic report include (a) robot error code number (ro), program step number (c), hand gripping status (ii), workpiece supply status (e), processing machine status (e), vision sensor image, etc., and the maintenance department ( 2) The receiving device reads the above information using the built-in display device or printer, performs a reception confirmation operation using the reception confirmation operation panel (2a), makes a comprehensive judgment based on the above information, and reboots if necessary. Each device is restarted individually using the operation panel (2b), and finally the entire system is restarted.

That is, Figure 2 shows the main configuration of the control panel (le) of the automatic driving system (1), and the robot (lb
), and each control means (10
a) and (10b) current storage means (10c) for storing the current status of the robot (1b) and peripheral equipment (contents to be automatically reported) when an earthquake is detected by the earthquake detector (1e);
, Similarly, an abnormal stop means (10d) for abnormally stopping the robot (1b) and peripheral equipment when an earthquake is detected;
Activation means (10e) for activating the automatic notification device (3a) of the automatic notification system (3), notification confirmation means (10)
f) and a restart means (10g) for controlling the restart of the robot (1b) and peripheral devices when the restart operation panel (2b) of the maintenance department (2) is operated, and a person connected to these. Output boat (10h), CPt1
(10i), RAM (10j) and ROM (10k
) equipped with a computer system.

FIG. 3 shows an operation flowchart of the CPU (loi) in the above configuration, and shows that when an earthquake is detected by the earthquake detector (le), the robot (1b) and peripheral devices are abnormally stopped (step S1), and the current status of each device is stored. At the same time, the automatic reporting system (3) is automatically activated to automatically report (steps 52 to S4). When the report is completed (step S5), press the reception confirmation operation panel (2) of the maintenance department (2).
After confirming the completion of reception from a) (step S6), the maintenance department (2) remotely confirms the status of the automatic driving system (1) (step S7), and then confirms the restart operation panel (2b).
) to restart the robot and peripheral devices based on the remote restart operation signal (step S8).

Therefore, from the maintenance department's point of view, accurate information is available, accurate responses tailored to the situation can be made in a timely manner, and systems can be restarted without dispatching personnel. Can be centrally managed.

Although this embodiment shows an example in which the system is stopped due to the ground M sensor, the same effect can be obtained in cases such as a failure of the workpiece chuck of the hand or a workpiece supply failure.

Further, in this embodiment, an example of a system centered on a robot is shown, but similar effects can be obtained even with an automatic driving system composed of a dedicated machine or the like.

However, in the event that peripheral equipment is severely damaged due to a runaway robot, etc., the appropriate worker can be dispatched in a timely manner to restart the system by looking at the vision sensor screen.

Note that the automatic driving system of this embodiment uses robots, hands,
Although the present invention is made up of a processing machine and a work supply device, the same effect can be obtained in an automatic operation system that does not include a robot or hand, but the robot and hand consist of a dedicated loader or the like. In addition, the maintenance department refers to a maintenance company that centrally manages a large number of robots and has dispatched personnel stationed at all times, but in the case of large companies, it may also be referred to as an in-house maintenance department. In any case, it refers to a place where countermeasures personnel are permanently stationed.

〔Effect of the invention〕

As described above, according to the first invention, when the automatic driving system malfunctions, the status of each device is automatically reported to the maintenance department at the same time as the failure, so there is no need for a supervisor for the automatic driving system.
In addition, sufficient reporting information allows for prompt and efficient response, which reduces system downtime.

Furthermore, according to the second aspect of the invention, since the system is restarted by remote control from the maintenance department, the downtime of the system can be shortened and the operating rate of the system can be improved.
