Abstract

PURPOSE:To reduce the number of push buttons, by counting the number of control push buttons, by counting the number of times of turn-on of a push button so that addition of a counted number of times of turn-on of the push button within a predetermined time is carried out and then the result thereof is delivered to a machine control device. CONSTITUTION:In the case of advance of an apparatus, a push-button is depressed three times within a predetermined time TOUT. A control circuit starts a timer, simultaneously with the first time of depression, and sets a depression number counter to one (1). Subsequently, the number of depressions on the counter is increased by one (1) each time the push button is depressed, and the number of depressions is counted. At the time 4-4 at which the predetermined time TOUT has elapsed, the apparatus 1-12 which corresponds to the number (3) of depressions of the push button counted by the counter is driven.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a machine control operation panel.

Machines such as machine tools and industrial machinery are usually equipped with multiple attached devices, and in order to operate these devices fully manually and independently, the control panel requires the same number of pushbuttons as the devices.

Therefore, conventionally, as shown in FIG. 6, a select switch 6-1 for selecting the device and a start valve button 6-2 are provided on the operation panel to operate the device.

First, a method was adopted in which a corresponding device was selected using a select switch 6-1, and then a starting valve button 6-2 was pressed.

However, even with the above method, a select switch 6-1 is required in place of the start valve button 6-2, and it is impossible to reduce the number of switches of this kind on the control panel.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a machine control operation panel that can operate a plurality of devices with one pushbutton and can reduce the number of operation pushbuttons.

In order to achieve all of the above objectives, the present invention provides means for detecting the ON and OFF states of the button switch when the 0N-OFF press is pressed, means for counting the ON times, and means for counting the ON times within a predetermined time. Add the number of times.

This and the means for outputting to the machine control device constitute a machine control operation panel according to the present invention, which is characterized by its features.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a plan view of a cylindrical grinder as an example of a numerically controlled machine tool, Fig. 2 is a block diagram showing the configuration of the control device of the cylindrical grinder, and Fig. 3 is a side view of the attached equipment of the cylindrical grinder. 4 is an explanatory diagram of the principle of the present invention, and FIG. 5 is a program flowchart for implementing the method shown in FIG. 4.

In the cylindrical grinder shown in FIG. 1, a grindstone 1-2, which is a processing tool, rotates at a circumferential speed vG on a machine main body 1-1.
The grindstone 1-2 is configured to be movable via a numerically controlled tool cutting motor 1-3 and a tool cutting feed mechanism 1-4.

On the other hand, as shown in the figure, the workpiece 1-9 is supported at both ends by the workpiece support center 1-7, 1-8, and the workpiece 1-9 is rotating at a circumferential speed Vw. , this is a numerically controlled motor 1-5 for moving the workpiece and a feed mechanism 1-6.
It is configured to be movable.

In addition, %1-a, 1-b, 1-c in FIG. 1 are the processed parts 'PJr? of the workpiece 1-9. l: indicates, 1-10.1
-11°1-12 indicates attached equipment.

By the way, as shown in FIG. 2, the operation of the cylindrical grinding machine is controlled by a control device #2-2 interposed between the machine body 1-1 and the machining data input/output device 2-1.

As shown in the figure, this control device 2-2 includes a central processing unit (CPU) 2-3. System path 2-4. Processing data input/output device interface 2-5. System control program storage memory (ROM) 2-6. Machining data program storage memory (RAM) 2-7. It is composed of an interface 2-8 for machine control signal output (SOUT) and an interface 2-9 for machine control signal human input (SIN).

Fig. 3 shows the attached equipment 1-10゜1- shown in Fig. 1.
11. r-12 details M[l-shown, these attached equipment 1
-10.1-11.1-12 is a fixed size r-gear for measuring the diameter of the workpiece 1-9, and the workpiece parts 1-a, 1-b, 1- For the measurement of c, instruments 1-12.1-11.1-10 are used, respectively.

By the way, in Fig. 3, 3-1 is the measuring part of each device, and this is the part that converts the total diameter of the workpiece 1-9 into the displacement of the arm 3-3 (1111). Reference numeral 2 denotes a driving section, which moves the measuring section 3-1 forward as shown by the chain line in the figure during measurement, but normally it moves the workpiece 1-1 forward.
In order to avoid interference with 9, it is retreated as shown by the solid line in the figure.

Below are multiple of the above attached equipment 1-10.1-11゜1-1
2, the method by which the operator operates the operation panel F (forward and backward) will be fully explained.

FIG. 4 shows the state of the device operation push buttons.

, normally the pushbutton is in the 0FF4-0 state. still.

The attached devices 1-10.1-11.1-12 to be operated are numbered 1 and 2.3, respectively, for identification.

Now consider the case where the third device 1-12' is moved forward. The operator presses 'I'otr' for a certain period of time as shown in Figure 4.
Press the push button all three times within r. The control circuit starts the T'out timer at the same time as the first button press (4-1 in Figure 4), sets the valve number counter to 1,
After that, each time the push button is pressed, the number of valves on the counter changes? ! Calantulate the number of valves by increasing by -1. And 'I'
At time point 4-4 when the o'r time has elapsed, the device (device 1-12 in this example) corresponding to the number of push button valves counted by the counter (3 in this example) is fully driven.

The method mentioned above? The program flowchart for expressing +1 is shown in Fig. 5, and according to this, the first
Waiting for the second button press, if it turns on, the next process 5-2
Move to. In step 5-2, after starting the 'rotrr timer, the initial value of the valve number counter is set to 1, and thereafter the value of this counter is increased by 1 each time the button is pressed to count the number of valves. Then, in the fifth step 5-3, the button waits for OFF, loops while the button is ON, and then the button is OFF.
Then, the process moves to the next process 5-4. In 5-4, press the push button again and check that the TOUT time has elapsed, and 'I'ou'r
If methane is pressed again within the time, the process jumps to 5-5, and if the Totrr time has elapsed, the process moves to 5-6, and devices corresponding to the number of push button valves (counter value) are driven. In addition, at 5-5, the press counter is increased by 1, and from then on, it is 5-3.
Return to

As described above, according to the present invention, equipment can be selected and started with one pushbutton, so the number of operation pushbuttons etc. on the machine control operation panel can be significantly reduced, and the operation panel can be made compact. It can be made into something.
