Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video educational apparatus for educating required items such as a structure of a processing facility or equipment, an operating method, a maintenance / inspection method, a maintenance / restoration method using video information.

[0002]

2. Description of the Related Art In recent years, various machines have come to be dynamically controlled on a processing cell or line due to the progress of FMS and CIM.

For example, in a sheet metal processing line equipped with an automatic warehouse, a press machine, a material carrying-in / out apparatus, etc., each machine is connected to a local area network (LAN), and the press machine is monitored by a monitoring control room. A plate material (work) to be processed is automatically supplied only by giving a start signal, and a pressed product as a product or a semi-finished product is automatically shipped via an automated warehouse or not.

Here, the operator (operator) located on the processing line is required to make a condition for each machine to operate, that is, a setup work, and perform the setup work while communicating with the monitoring control room. It is necessary to monitor each machine above and perform the next setup work.

Further, when each machine generates an alarm, it is necessary to temporarily stop the other machines, cancel the alarm, and then restart the machine. That is, the worker needs at least the knowledge and skill to start and stop each machine and to release the alarm for a slight alarm.

[0006]

However, in recent years, there has been a shortage of manpower in each industry, particularly called 3K, where workers are not gathered for dangerous, dirty, and hard work. .. Even in each processing industry, there is a lot of leakage, and it is difficult to secure an operator who has acquired the above minimum knowledge.

Incidentally, each processing line has seasonal workers, part-time workers, part-time students, foreign workers, etc.
Many ordinary workers are hired.

On the other hand, the machining lines of recent years are oriented toward FMS, and the control devices of each machine have different arrangements of switches on their operation panels, and their operation methods are also different. , It is a difficult skill to educate the above workers so that they can handle all machines.

On the other hand, in recent years, processing machines have been exported at the world level. However, it is difficult to make various manuals for export machinery so that engineers in the country can understand it in the language of the country. Also, even if the instruction manual is completely created, it is difficult to read the characters in order.

Therefore, in the present invention, in view of the fact that the video education is visual and effective, and the simple education is sufficient, the configuration of each facility in each processing facility or each equipment, the operating method, the maintenance inspection are performed. It is an object of the present invention to provide a video education device that surely teaches necessary items such as methods and maintenance and repair methods by using video information.

[0011]

The present invention for solving the above-mentioned problems constitutes a video education apparatus as set forth in the claims.

[0012]

In the video educational apparatus of the present invention, the video information storage apparatus is divided into educational video information with audio information about required items such as the configuration of each facility or equipment, operation method, maintenance and inspection method, maintenance and repair method. It is possible to project each item and to make a condition determination while inputting output information from the target equipment or device, and provide optimal explanation or work support according to the current state of the equipment or device.

When the target device is a numerical value other control device, if a screen for video projection and switches for giving operation signals for projection processing are provided separately from those of the numerical control device, no mutual relation occurs. So you can use it without confusion.

Further, when the target equipment or device has an alarm generating function and the video information teaches how to deal with this alarm, the projection processing apparatus detects an alarm detecting means for detecting the alarm. And a video information selection means for selecting predetermined video information according to the detected alarm type, and a cue means for automatically cueing the selected video information. Law videos can be automatically projected, and alarm handling can be performed easily and reliably.

In general, a large number of function switches are provided in the operation switches, and one function is called and executed only by operating these switches. Incidentally, the switches with a graphic display shown on the left side of the numeric keypad are used when creating a machining program, and each switch designates the machining of the pattern shown by the graphic. On the screen 43A of the CRT 43, data for supporting the work at the time of creating the NC program is displayed, the current state and the like are displayed during processing, and data necessary for alarm processing is displayed during alarm processing. However, the alarm processing method shown here is based on characters or the like, and is a general method that is difficult to use unless it has some knowledge.

FIG. 6 is an explanatory view showing the external appearance of the video education device 21 according to the embodiment of the present invention. The video education apparatus 21 comprises a television 51 on a television stand 50, and a shelf formed in the stand controls a general VTR device 52 and the VTR device 52 in an interlocking relationship with target equipment or devices. The projection processing device 53 is stored. An IC card 54 as a video control information storage device can be attached to the projection processing device 53. An educational video tape cassette 56 is stored in the door 55 as appropriate. Generally, the cassette 56 is created for each target facility or device.

The television 51 is provided with a CRT screen 57, on which an operator 58 can be located. The orientation of the screen 57 can be appropriately adjusted so that the operator 58 can easily see it and the operator 58 can observe the target facility or equipment while viewing it.
For this reason, casters 59 are attached to the lower side of the base 50 so as to be able to appropriately correspond to the target facility or equipment. A cable (RS2332C) for serial data transmission equipped with a connector 60 is attached to the side of the base 50 and is connected to the serial interface of the target facility or equipment.

The operator 58 carries a remote controller 61 of a wire type, and can wear a headphone set 62 connected to the remote controller 61.

In the above structure, the connector 60 is connected to the serial interface of the target equipment or device, and the cassette 56 created according to the target equipment or device is VT.
The IC card 5 that is attached to the R device 52 and that is compatible with it

FIG. 7 is a block diagram showing the hardware configuration of the projection processing device 53. As shown in the drawing, the projection processing device 53 includes a bus 63, a CPU 64, a ROM 65,
The RAM 66, the SIOs 67, 68, 69, and the Do 70 are connected, and the SIO 67 is connected to the SIO 35 of the NC device 12 via the connector 60. I for SIO68
A C card interface 71 is connected to which the IC card 54 described above can be mounted. SIO69

The R controller 72 is connected to the above-mentioned VTR device 52, the remote controller 61, and the headphone set 62.
LEDs 73 are connected to the Do 70. This L
The ED 73 is provided on the operation surface of the VTR controller 72. In this example, various switches are provided on the remote controller 61, but operation switches can be appropriately provided on the VTR controller 72.

FIG. 8 is an explanatory diagram of data stored in the IC card 54. As shown in the figure, the IC card 54 stores information for displaying a table of contents, video position information, and control information for each item. It also stores the relationship between the items shown in the table of contents (see FIG. 12). These pieces of information are created for each cassette 56, but the IC card 54
Need not be set for each cassette, but information about a plurality of cassettes can be collectively stored. The table-of-contents display information is for displaying the contents of each cassette on the front surface 57 as a table of contents. The code for each item is displayed in this table of contents. The video position information indicates which item is stored in which position in the cassette, and is indicated by the cassette rotation amount count value Pi (i is an item number). The control information for each item is defined for each item, and at a certain position,
Alternatively, under certain conditions, conditions such as temporarily stopping the cassette, jumping to another item, or waiting for a condition such as waiting for a signal are set.

FIG. 9 is an explanatory diagram showing items of video information stored in the cassette 56. Cassette 56 of this example
1 indicates each position Pi (i = i) corresponding to each item code Ti.
1, 2, ...), description of machining line, pre-start inspection method, start method, origin return method, material setting method, mold replacement method, automatic operation method, manual operation method, overtravel processing method, override processing method, ... Many educational video informations are stored. Since these pieces of information are basically used individually, it is better to organize them as much as possible by visual search, but basically various kinds of information may be mixed and stored. The relationship between each item is IC
It is stored in the card 54.

FIG. 10 is a flowchart showing a projection method for general description. VTR in step 1001
When the cassette 56 is inserted into the device 52, step 100
At 2, the tape is rewound. Therefore, the operator 58 uses the remote controller 61 to input the items to be trained.
This is determined in step 1003, and step 1004
In step 1005, the item is displayed, and in step 1005, a projection of the video information is displayed on the screen 57.

Next, step 1006 in which the projection is started.
In step 1007, the NC device 12 and the tape position are monitored until the end is determined in step 1007.
At 08 and 1009, the condition in the control information written on the IC card 54 is determined.

If a tape temporary stop command for waiting for the condition is judged in step 1008, the tape is temporarily stopped at that position. This is a countermeasure in anticipation of a case where the operation of the NC device 12 is instructed and it takes time. The screen may be fixed during this period. After the suspension, wait for the condition in step 1010, then step 1
If the condition inputs are complete in 011, the process moves to step 1006. Step 1009 waits for a time.

Specifically, for example, the starting method (T3)
Then, first select the "origin" in the mode selection on the operation panel surface 48 of the NC device 12, and operate the origin movement keys "+ X" and "+ Y" to select the "X-axis origin" and "Y-axis" on the LED display at the lower left of the panel. Since the mode can be switched to "automatic" after the "origin" lamp is turned on, in order to execute these procedures, a sequential procedure may be displayed on the screen 57 and guidance may be provided by video and voice. The tape can automatically jump to the origin return method (T4). During these times, the CPU 64 monitors the operating state of the NC device via the RAM 66, and the next procedure will be described in accordance with the conditions.

By the above processing, explanation images for various educational items are displayed on the screen 57 shown in FIG. 6, and based on the images, the line configuration, the structure of the punch press machine 9,
It is possible to know each item shown in FIG. 9, such as the pre-start inspection method and the start method. In addition, as educational contents, since it is possible to proceed while observing the explanation subject and while monitoring the operating state, the explanation is easy to understand and video redundancy can be omitted.

FIG. 11 shows educational items for dealing with alarms. This is not to explain the content of the alarm, but to deal with the alarm that actually occurred. An alarm processing method corresponding to each alarm code is stored in each position Pi of the cassette 56-2.

For example, in the override (A2), a part of the work clamp device comes too close to the mold, and if punching is performed as it is, there is a possibility that part of the work clamp device is punched by the mold. Therefore, when this state occurs, an alarm (A2) is generated, and the NC device enters the suspended state. In this state, the operator observes whether or not the work clamp device may actually be punched, and if there is no danger of punching, the start button is pressed to continue the machining. The video about the overriding method explains this using images and teaches how to confirm. During this period, the signal state of the NC device 12 is also confirmed, and either the machining position is skipped to continue the machining, or the work is supported to continue the machining from that position. When asking whether there is any other method than skipping the processing of the position, the stored information of the IC card 54 is queried, and the video network shown in FIG. It is also possible to jump to the video information of. The information shown in FIG. 11 may be mixed in the information of FIG. 9 as described above.

As described above, the operator 58 can carry out the work in accordance with the instruction of the video shown in FIG. 11, and can take appropriate processing for the turret punch press machine 9 and the NC device 12. The same applies to maintenance, inspection and maintenance. In addition to this, desired information can be added to the video 56. In addition, IC card 5
It is also possible to incorporate a high level control information in 4.

FIG. 12 shows a network structure of video information. In FIG. 7, video items Ai, Bj, and Ck are networked so that various kinds of education can be supported by selecting i, j, and k. By combining video information in this way and jumping from information to information as appropriate,
For example, when a certain item is insufficiently explained, a specific contact place is taught, and a small amount of information can be used for a large number of educations.

FIG. 13 shows a screen 57 of the video education device 21.
Is provided on the panel 75 together with the operation switches thereof, and is rotatably provided on the side surface of the NC device 12. The control member of the video education device 21 is stored in the box of the NC device 12. In this example, the remote controller 61 is omitted, and switches for operating the VTR are provided on the panel surface instead of the remote controller 61.

In this example, the panel 75 is always set to the NC device 1.
The video teaching device 21 has an advantage that it does not occupy a space because it coincides with the side wall of 2 and is rotated when not in use so that the screen 57 can be seen easily. Even in this case, it is better not to match the screen 57 with the screen of the CRT 43 of the NC device 12. This is because the video education device 21 of this example is used while the NC device is in operation, and the CRT 43 wants to display the state of the NC device. Further, it is better to provide the switches on the panel 75 separately from those of the NC device 12. This is because, when the NC device 12 is shared with that of the NC device 12, it becomes necessary to further increase the number of switches that are too many in number, which complicates the switch function.

In the above description, the video education device 21 is set to N.
Connected to the C device 12, the turret punch press machine 9 and NC
I trained about device 12, but video education device 2
1 may be used by being connected to another device such as the IMC 16 or the stocker controller 11. In this case, the cassette 56 and the IC card 54 will be replaced accordingly. The IMC 16 can teach how to set a schedule, how to use the automatic programming device 17, and the like. The ISC 11 can teach the explanation of the automatic warehouse 3, the material storage method, the manual operation method, and the like.

In the embodiment shown above, the video education device 2 is used.
Although the remote controller 61 and the headphones 62 are connected to the No. 1 in a wired manner, it is possible to make them wireless properly.

In the above embodiment, the video education device 2 is used.
Although the screen 57 of No. 1 is provided separately from the CRT 43 of the NC device 12, the screen 57 is also used as the CRT 43 by performing only a brief explanation or by appropriately switching to the original display of the CRT 43. It is also possible. However, even in this case, it is better to provide the switches for the video education device separately from that of the NC device. This is because it is not necessary to cause confusion in the operation of the NC device 12. It is also possible to configure the educational video screen within the window of the screen for operating the NC device.

Further, in the above embodiment, the video tape is used for storing the video information, but a CD or other medium may be used. Further, it may be diverted to another device through the LAN 15 or may be transferred from outside the factory via a telephone line.

The present invention is not limited to the above embodiments, but can be carried out in appropriate modes by making appropriate design changes.

As described above, since the present invention is the video education apparatus as described in the claims, it is easy to understand by using the video information for general explanation of the processing equipment or each equipment and work support. be able to. Moreover, the video education device is provided with control information for controlling the video network such as searching the video network appropriately for each education item, and the condition determination is performed while inputting the output information of the target, so that the education according to the target can be appropriately performed. It can be carried out.
