Further, when the playback switch 3 and the knob switch 5 are turned on, an alarm for starting the playback function operation is issued, and an alarm is issued at the end of the playback work. Therefore,
The operator does not waste work or waste time.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a work automation device for a construction machine, particularly a hydraulic power shovel.

[0002]

[Prior art]

 The system of a conventional work automation device for a hydraulic power shovel is as shown in FIG. The monitor 1 is provided with a teaching switch 2 for selecting the teaching mode and a playback switch 3 for selecting the playback mode, and the electric lever 4 for operating the working machine operated by the operator is taught only while the switch is ON. Also, a knob switch 5 for activating the playback function is provided. The electric lever and each switch are connected to a controller 10, and the controller 10 is connected to an actuator 13 such as a working machine or a turning device via an electro-hydraulic conversion system 12.

Next, the operation will be described. To perform the teaching operation, turn on the teaching switch 2 of the monitor 1 to select the teaching mode, turn on the knob switch 5 of the electric lever 4 and operate the electric lever 4, and the controller 10 operates the electric lever 4. A signal corresponding to the amount is transmitted to the electro-hydraulic conversion system 12, and the electro-hydraulic conversion system 12 converts the electric signal into hydraulic pressure to operate the actuator 13, thereby operating the working machine, the turning device, or the like. At the same time, the teaching operation is performed and the controller 10 stores the operation amount of the electric lever 4. When the knob switch 5 is turned off, the teaching operation ends.

To perform a playback operation, the playback switch 3 is turned on to select the playback mode, and the knob switch 5 is turned on. Then, the controller 10 outputs a signal of the operation amount of the electric lever 4 stored by the teaching operation. A playback operation is performed in which the output is performed and the same working machine operation as that performed in the teaching mode is performed via the electro-hydraulic conversion system 12. When the knob switch 5 is turned off, the playback work ends.

[0005]

[Problems to be solved by the device]

 According to the above configuration, after the teaching or playback selection switch is turned ON, the knob switch is turned ON to perform each operation. Therefore, the teaching mode does not enter the teaching mode due to an input error of the knob switch during teaching, and even if the teaching operation is not performed, the operator does not notice and continues the electrical lever operation as it is, resulting in unnecessary work. There is a problem.

In addition, when playing back, it is not clear when the playback starts and when it ends, so it is wasted time by waiting for the operator to wait or until the playback work is completely confirmed. There's a problem.

The present invention has been made in view of the above problems, and makes it possible to clarify the start and end points of the operation of each mode, and to perform automatic work without performing unnecessary work or wasting time. It is an object of the present invention to provide an alarm device for an electronic device.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, in the first invention of the alarm device of the work automation device according to the present invention, the operation amount of the operator's work machine is stored in the teaching mode, and the operation amount stored in the playback mode is output. In a work automation device for a construction machine that causes a working machine to perform a playback operation, an alarm device is provided to notify that the teaching function and the playback function are in operation. In the third invention, the alarm device issues an alarm when the teaching function is activated and when a predetermined time has elapsed after the activation of the teaching function. In the third invention, the alarm device is played back. The feature is that an alarm is issued at the start of function operation and at the end of playback work.

[0009]

With the above configuration, an alarm is issued when the operation of the teaching function is started and when a predetermined time has elapsed after the operation is started, and when the operation of the playback function is started and when the playback work is completed. Since the alarm device for issuing an alarm is provided, the operator can know that the teaching function has started to operate and that the predetermined time (the time limit determined by the storage capacity) has been reached. Also, it is possible to know the start time of the playback function and the end time of the playback work.

[0010]

【Example】

 An embodiment of an alarm device of a work automation device according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a system of the present invention, and a difference from the conventional system shown in FIG. 2 is that a buzzer 11 is provided and connected to a controller 10.

The buzzer 11 turns on the teaching switch 2 of the monitor 1, turns on the knob switch 5 of the electric lever 4, and issues an alarm when the operation of the teaching function is started, and outputs a warning for a predetermined time, that is, a storage capacity. It is set to issue an alarm when the time limit determined by is reached.

Further, the buzzer 11 turns on the playback switch 3 and turns on the knob switch 5 to give an alarm when the operation of the playback function is started, and the reproduction of the memorized portion is finished, and the playback work is completed. Is set to issue an alarm when is completed.

Therefore, the operator can know the operation start timing of the teaching function, the time when the time limit is reached due to the storage capacity of the teaching function, the operation start timing of the playback function, and the completion time of the playback operation of the memory. .

[0014]

[Effect of device]

 As described above, the present invention is applied to the teaching of a construction machine, the operation method of a playback type work automation device, when the teaching function is activated, when the time limit is reached due to the teaching memory capacity, when the playback function is activated, and when the memory portion is played Since the operator has an alarm device that issues an alarm when the work is completed, the operator can know the exact time, and the alarm of the work automation device that does not waste work or waste time. The device is obtained.
