JPS6092100A - Main operation board of press - Google Patents

Abstract

PURPOSE:To provide a main operation board of a press which enables various displays, deals quickly with trouble and prevents decrease in working efficiency by using a cold cathode ray tube as a display means of said board. CONSTITUTION:Various ets of information are fed from a main body 7 of a press to a control circuit 8 and are displayed on a CRT2 via an interface 9. Kinds of displays are selected by push buttons 5; for example, trouble, preparatory plan, working efficiency and load rate can be selected. If the trouble is selected, a fault, prediction and time over can be further selected. More specifically, the content of the fault, the point of the fault, the method of processing the fault, the content of the prediction, the predicted point, the processing method for prediction, etc. are displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a main operation panel having display means for displaying various malfunctions during operation of a press.

The press machine is equipped with a main operation panel, and the main operation panel has display means such as the interlong display of the press, troubleshooting methods, and instructions on the location of reprints of the fourth edition, which is different from conventional display means. was performed by many display burns.

However, if there was a problem caused by this conventional display, it was difficult to tell where the extra issue was or what the problem was, and it was not possible to deal with it quickly, which ultimately led to a decline in the operating rate of the press.

The present invention has been made in consideration of these points, and it is possible to display any kind of information, and it is easy to understand the content of the trouble, and the trouble can be dealt with quickly. An object of the present invention is to provide a main operation panel having a display means that can also display production management information.

The present invention is characterized in that a cold cathode ray tube (CRT) is used as the first display stage.

As is well known, a CRT can display numbers such as 0, 0, and so on, making a variety of displays possible.

In the present invention, the interlong, electrical equipment extra edition location, l/ruble processing, display or operation of the operating system, etc./V table 4<,
Displays heli angle, predictive diagnosis, failure diagnosis, timetable, 1ζ, crank angle, etc.

Next, preferred embodiments of the present invention will be described. FIG. 1 is a front view of the main operation panel, and l is the operation panel that can be expanded with various parts.It can be opened and closed by a hinge 3. A CRT 2 is provided at one end of the knob 1, a switch and a pushbutton 5 are provided on the door side, and a stop button 6 is provided at the end. Note that 4 in the figure indicates that the main operation panel 1 is fixed 1. It is a screw to keep it in place.

FIG. 2 is an overall block diagram, in which various information is sent from the press body 7 to the control circuit 8 and displayed on the CRT 2 via the Inter 2Ace 9. The type of display is selected by pushbuttons 5, and in the embodiment, trouble 1
1, setup 12, operation rate 13, and load rate 14 can be selected (Fig. 3).

If you select Trouble 11, you can further select Failure 11a, Prediction 11b, and Time Over+1c. location, predictive processing method,
Also, display the time over content, time over point, and time over handling method. Also, when setup 12 is selected, Bolster landing, Bolster person, Bolster landing, Bolster clamp, Safety guard lowering, Slide lowering, Slide bottom dead center, Upper mold clamp, Slide "-lift",
In addition to displaying the slide positioning values sequentially, the number of pieces produced,
The data contents of 11 of die-hyde, transfer feed dimension, and feed bar are displayed simultaneously. Further, when the operating rate 13 is selected, the operating rate is displayed in %, and when the load factor 14 is selected, the percentage of the press capacity used is displayed.

The control device 8 has a CPU 15 as shown in FIG.
The information is manually calculated via the interface 17 and the results are displayed on the CRT 2. CPU15
Enter various information and data on keyboard 1 to + + F4.
Let's do it manually from 0.

These operations, especially the interlong, will be explained based on the flowcharts shown in FIG. 5 and subsequent figures. FIG. 5 shows the operating mode. After starting, adjust the slide, run the moving bolster, clamp the upper mold, and start press operation. Each operation is displayed on the CRT 2, and the interlocks 18 provided for each are displayed.
The respective operations will be monitored on 19.20.21. The flowchart of the interlock described above is as shown in FIGS. 6 to 9.

The subroutine of the interlock 18 for the operation of sliding and f-adjustment is shown in FIG. 6, in which the lubricating oil, balance pressure, and press bottom dead center are checked, and if there is a problem with any of them, that fact is displayed on the GRT 2. The interlock 19 subroutine for moving bolster travel is shown in FIG. 7, and similarly to the above, the operating oil pressure, press localization value, feeder midpoint, feet per joint unramp, and pad lower limit are checked and displayed. The subroutine of the interlock 20 of the upper die clamper is shown in FIG. 8, in which the localization value of the moving bolster (MB), press bottom dead center, and operation selector off are checked and displayed. The interlock 21 subroutine for the final press operation is shown in Figure 9, which checks the inter-gliding oil pressure, clutch air pressure, balance air pressure, moving bolster positioning value, foot barge joint clamp, upper mold clamp, and safety coupling, respectively. and display each on GRT 2.

In this way, in the present invention, the type of trouble, the location of the trouble, and even the treatment method (can be displayed on RT, so the trouble can be dealt with very easily. Not only troubles,
In the present invention, it is possible to display predictive diagnosis, failure diagnosis, time over, etc., as well as production management such as operation rate and load rate, thereby increasing the efficiency of press operation.
