Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multimedia NC control device capable of displaying a guide image relating to an operating method of a processing machine or its control device and a work processing technique.

[0002]

2. Description of the Related Art In recent years, processing machines have become more sophisticated, and their control devices, such as NC devices, have also become more sophisticated, and the operability of such sophisticated machines or their control devices has become a problem. .. That is, the sophisticated machine and its control device must be operated in accordance with the manual book, and must be familiar with the machine and control device in order to be able to perform efficient operation. Excellent processing technology also requires the operation of the control device.

However, it is a worker who operates the machine,
Specific schooling is required for them to become fully versed in machines and their controls.

Therefore, in order to guide the operation method of the NC device, there is an example in which a guide image of the operation method is displayed on the CRT screen of the NC device. With this device,
Since the video information for operating the NC device created in advance is displayed on the screen of the NC device, even a person unfamiliar with the NC device can operate while referring to the information.

[0005]

However, the video education system in which the operation system is shown on the screen of the NC device as described above has the following various drawbacks and cannot be put to practical use. There was a point.

[0006] Since the screen is shared with the screen of the NC device for competition, there are many restrictions and usability is poor.
That is, the screen of the NC device refers to the screen of the MDi (manual data input) device in a broad sense, but various information must be displayed on this screen for operating the NC device or for editing the NC data. In some cases, the educational image cannot be displayed due to the relationship between the image and the educational image.

Since the educational video is limited to the operation of the NC device, the educational video cannot be fully utilized. In other words, as an educational video, it is necessary to explain the work, the machine and its system, the alarm coping method, the machining procedure, etc., and the motion guide of the person linked with the operation of the NC device.

[0008] Furthermore, since it is basically considered that one video information is manually operated and continuously sent, information corresponding to the operating state of the machine or the NC device cannot be sent, which causes a failure. Perfect. That is, for example, in the alarm coping method, not only automatic cueing is required according to the alarm, but it is necessary to know the current state of the machine even during the coping, and the education content should be changed accordingly. ..

Since the operator has to search for a required image by himself, it is far from practical use. The number of menus is also limited.

Since the screen of the NC device is used as the education screen, it is not possible to receive education unless standing up in front of the board of the NC device, and cannot be used by anyone other than the NC device operator such as a machine operator. That is, for example, when a machine operator is trained in machine operation, he / she must go to the NC device each time. In addition, the screen is too small to be easily seen, which greatly limits its applications.

Therefore, an object of the present invention is to provide a multimedia NC control device including a processing machine and its control device, which can appropriately guide its operation and processing technology.

[0012]

In order to solve the above problems, the present invention comprises a multimedia NC controller as set forth in claims (1) and 1 (2).

[0013]

In the multi-video education device according to claim (1), a large liquid crystal display screen is formed on the surface corresponding to the operator of the processing machine, and various educational video information is displayed on the screen.
Therefore, there is no problem of interaction between this screen and the screen of the NC device, and video information can be flowed while using the NC screen normally. Also, since a large screen is formed on the side of the machine, it is easy for the operator to see and it is not necessary to go to the front of the NC device one by one. The large size means that the size is 14 to 50 inches, and it is a level that a general operator can easily observe while operating.

Further, since the video control device is connected to a control device of a machine such as an NC device, it is possible to provide appropriate guidance according to the state of the machine or the control device.

On the other hand, in claim (2), a text image and a moving image are combined on the same screen, and when necessary, the required image is provided fully automatically without an operator's hand by an appropriate expression method. To do.

As educational multi-video information, in addition to the operation system of the NC device, the handling of the work, the explanation of the configuration of the machine and its control device, the alarm coping method, the configuration of the connection system, the machine operation system, the processing system are explained. It is possible to prepare a desired one. In addition, it is free to display images to improve the environment.
