Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an operation control device for a processing machine.

(Prior Art) In a conventional operation control device, for example, an operation control device of a section steel working machine for processing an angle material or a channel material, a manual button for switching to a manual mode is pressed to perform a manual operation, and then a plus operation is performed. The push button for moving in the direction or the push button for moving in the minus direction was pressed, and the stopper was moved manually. In order to select the operation mode, the user must first press the automatic button to switch to the automatic mode and then press the start button to position the stopper. Was needed.

As described above, in general, the provision of the mode changeover switch separates each operation mode such as the origin mode, the storage mode, the manual mode, and the automatic mode into other modes, entrusts the operation contents to a predetermined sequence, and ensures each operation. This is to make it easier.

(Problems to be Solved by the Invention) However, the conventional operation control device as described above requires push buttons (or key switches) for switching to each operation mode, and the number of push switches on the NC operation panel is limited. It was felt that the operation method was difficult in appearance. In order to make the operation procedure as simple as possible, it is necessary to save time and effort for mode switching.

In particular, in the case of a section steel working machine, when it is necessary to provide an operation switch for process editing on a small operation panel, there is a demand for reducing the number of buttons or keys as much as possible.

Therefore, an object of the present invention is to provide an operation control device of a processing machine in which the number of operation switches is reduced and operability is good.

[Structure of the Invention] (Means for Solving the Problems) The operation control device for a processing machine according to the present invention for solving the above problems has an origin mode C1, a storage mode C2, a manual mode as shown in FIG. Equipped with a plurality of operation modes such as mode C3 and automatic mode C4, the operation control device of the processing machine that enables each operation mode while interlocking with other modes has dedicated mode switching means for switching each operation mode. Instead, multiple operation switches C5 used in each operation mode
And a mode setting means C6 for automatically setting the current operation mode based on the operation status of these operation switches 5, interlocking the other modes, and enabling operation in a predetermined operation mode. And

(Operation) In the present invention, the operability is improved by eliminating the pushbuttons and key switches for mode switching that have been operated when switching modes in the related art. For example, if the origin return button is pressed, the stopper starts the origin return, and the manual operation is started by pressing the manual button. One step, program,
If the user presses the storage button or the like, the mode is changed to the storage mode, and the data input state is set. By pressing the start button, positioning can be performed at the set data.

(Example) Hereinafter, an example of the present invention is described using an example of a section steel processing machine.

Referring to FIG. 2, FIG. 3, and FIG. 4, the section steel working machine 1 includes a general body frame 5 in which left and right side frames 3R and 3L of a C-shape are integrally assembled. . The main body frame 5 is provided with a fixed table 7 for supporting a long work W such as an angle iron or the like.

On the right side of the table 7, a material feeding table 9 for supporting the work W and feeding the material in the direction of the table 7 is provided. The left end side of the channel-shaped support frame 11 for supporting the material feeding table 9 is fixed to the table 7, and the right end side is a column.
13 is supported. A roller stand for supporting a long work W at one end side is further to the right of the material feeding table 9.
15 are erected.

On the other hand, a sizing table 17 corresponding to the material feeding table 9 is disposed on the left side of the table 7. The sizing table 17 is for supporting one end of the work W and positioning the one end, and is a channel-shaped sizing frame 19 extending in the left-right direction.
It is supported by. This fixed frame 19 has a plurality of columns 21
Supported by.

Table 7, support frame 11, roller stand 1
5. A cantilevered support roller 23 that supports the work W at an appropriate interval is supported on the fixed-size frame 19 with its height adjusted to a horizontal plane.

The sizing table 17 is provided with a sizing device 27 having a stopper 25 for positioning the work W on the left end side of the work W so as to be freely positionable in the left-right direction (X direction). The sizing device 27 is movable in the X direction by driving a DC servo motor 29, and the stopper 25 can be positioned at an arbitrary position on the X axis.

A turret table 33 having a plurality of molds 31 for performing shearing, punching, or bend processing on the work W is mounted on the main body frame 5 so as to be rotatable and movable back and forth (Y direction). To move the turret table 33 back and forth, a handle 37 is provided on a part of an operation panel 35 attached to the front of the table 7. Therefore, the turret table 33 can be operated in the Y direction by rotating the handle 37 clockwise or counterclockwise.

Further, an upper frame is provided on the upper part of the main body frame 5.
39 is supported by the side frames 3R and 3L. The upper frame 39 has a ram for pressing the mold 31 indexed and positioned at a predetermined position for processing the workpiece W.
41 is mounted to be able to move up and down freely. The ram 41 is moved up and down by a hydraulic cylinder or a crank mechanism. Knobs 43 and 45 are arranged on the right side of the operation panel 35 to adjust the ram speed and the ram pressing force of the ram 41.

For example, the side frame 3R in the main body frame 5
A cable duct 47 is erected at a position close to, and an NC control panel 49 is provided above the cable duct 47,
On the upper frame 39 close to the NC control panel 49, a name plate 51 showing an outline of an operation procedure is attached.

In the steel shaping machine having the above configuration, the work W
When the material is fed onto the support roller 23 from the side, one end thereof is positioned in contact with the tip of the stopper 25, and a predetermined X is set based on the operation of the ram 4 and the mold attached to the turret table 33. Shear, punch, or bend processing is performed at the position. The Y-axis position is appropriately adjusted by the handle 37.

Therefore, the operator first creates a program for machining the workpiece by operating the NC control panel 49, that is, a process program for positioning the sizing device 27, and numerically controls the servomotor 29 to sequentially execute the program. While abutting one end of the workpiece W against the stopper 25 whose position is changed for each process,
A predetermined processing operation is performed.

FIG. 5 is an explanatory view of an operation surface of the NC control panel 49, and FIG. 6 is an explanatory view of an operation procedure written on a nameplate 51 attached close to the NC control panel 49.

In FIG. 5, on the operation surface of the NC control panel 49, buttons or switches and indicators for program editing and / or execution, including an LED lamp for notifying an alarm or completion of positioning, are appropriately displayed using pictograms. It is arranged in order. "One process""Program""Sher""Punch""Bend""Dimensions(memory)" Pitch "Number"
"Manual (←, →)""Homereturn""Start""On"
The "off" and "stop" switches have a built-in lamp so that they can be turned on or off as appropriate.

 The general operation procedure is as shown in FIG.

That is, first, the no-fuse breaker on the back side of the electric box is turned on, the operation circuit key switch of the operation section is turned on, the oil pressure is turned on, and the home return button is pressed, the sizing device 27 is turned on beforehand. Home position return is performed automatically.

Next, if you press the "one step" or "program" button, in the "one step" you can select the desired processing mode from shear, punch, bend, input the dimensions,
By pressing the start button, one-step processing can be performed.

In this case, the NC device incorporated in the NC control panel performs positioning of the sizing device 27 to position the workpiece W at the input position, and various actuators and sensors, for example, shots for fixing the turret table 33. A process of inputting a pin fitting signal, turning on a predetermined LED lamp in a preset sequence, and enabling a transition to the next operation is performed.

On the other hand, when the "program" button is pressed, the lamp inside the sketch is turned on, and the input of the program number is prompted. Therefore, when the operator inputs a program number, a predetermined program processing can be performed in a predetermined processing mode by the already edited program or by the program to be edited.

As for the cutting (single size) work, it is shown that pressing the "shear" button, inputting a numerical value, and pressing the "start" button positions the stopper.

As for the punch (end face input) work, it is shown that the stopper is positioned by pressing the "punch" button, inputting the numerical value of the hole position, and pressing the "start" button.

As for the punching (pitch input) work, pressing the "punch" button, inputting numerical values of the hole position and the pitch, and pressing the "start" button indicates that the stopper is positioned.

As for the cutting (lot processing) work, pressing the "shear" button, inputting the dimensions and the number of cuts, and pressing the "start" button indicates that the stopper is positioned.

It should be noted that it is noted that the notation of the “start” and “stop” buttons can be turned off by moving the stopper 25 with a manual command button during notch processing. The Y-axis positioning during drilling is a Y-axis handle.
At 37 it is shown to do.

 FIG. 7 shows a block diagram of the operation mode transition method.

The operation modes of this example are four types: an origin mode, a storage mode, an automatic mode, and a manual mode.

The origin mode is divided into "return to origin", "pause", and "end to return" operations.

The automatic mode is divided into “automatic operation” and “automatic stop”.

The manual mode is divided into "manual button on (axis moving)" and "manual button off (axis stop)".

Therefore, in this example, after defining each operation in each mode as described above, the transition from each operation to each operation can be performed only in one direction as indicated by an arrow, and the necessary transition is It is designed to be migrated automatically.

As an example, first, when the origin return button is pressed for the operation of origin return, the “origin” button flashes and the mode becomes the origin return mode. So, "start" or "stop"
"One process""Program""Manual""Number""Pitch"
Press the button to stop temporarily. Also, after a pause,
Press the "Origin" button to return to origin operation. In each of these cases, the "origin" button is blinking since all are in the origin mode.

Next, after the return to origin is completed, "Dimensions (memory)""Oneprocess"
When the “program” and “number” buttons are pressed, the mode shifts to the storage mode.

In the storage mode, one-step operation and program input operation can be performed, and the operation can be shifted to the automatic mode by turning on the start button, and can be shifted to the manual mode by turning on the manual button.

In the manual mode, it is possible to shift to the storage mode by turning on the pitch, one process, program, size, and number buttons.

In the automatic mode, the mode can be shifted to the storage mode by operating the buttons for the pitch, one process, program, and number of programs.

As described above, in this example, it is possible to shift to a desired mode by operating an operation button related to the mode without providing a special mode selection operation button, and a required operation can be performed with a small number of operation buttons. You can do it.

 Next, a specific example of the operation will be described.

FIG. 8 is a flowchart showing an operation procedure of one process.

First, when "one step" is selected, the "one step" button is turned on. At the same time, in order to select the desired machining mode,
The "Sher", "Punch", and "Bend" buttons light up together, prompting you to make a selection.

Therefore, if the operator selects, for example, "shear", only that continues to be turned on, and the buttons for other processes are turned off.

Therefore, when a dimension is input using the numeric keypad, an "input" key is pressed, and a "start" button is pressed, the "start" button is turned on, and one-step work is started.

On the other hand, if the user presses the "start" button without pressing the "input" key after inputting the dimensions using the numeric keypad, it will be an alarm.

On the other hand, if you press the numeric key after selecting one process, the "Sher", "Punch", and "Bend" buttons for each processing mode go out. Even if you press the start button here, it will be an alarm, but then press the "Enter" key. When the user presses the start key, the "start" button is turned on, and the stopper 25 can be positioned. If the "delete" key is pressed in the middle, it is possible to return to the position of the intended machining mode selection command. These operations are effective when the stopper 25 simply needs to be moved once.

FIG. 9 is a flowchart of the program input operation method.

First, when the "program" button is turned on, the "program" blinks.

For new entry, use the numeric keys to enter the program number,
For example, when "7" is input, this value is displayed on the 7-segment display, the LED lamp provided above "set value" is turned on, and the button indicating each processing mode blinks.

Therefore, when the machining mode is selected, the dimension (memory) key blinks. Therefore, when data is input and the start button is pressed, "start" lights up, and the data of the first process is displayed on the set value display section. .

On the other hand, when recalling a stored program, after inputting a program number, for example, "5", using the numeric keypad, the stored setting data for one step of the machining mode is displayed. Then, the blinking program button changes to lighting, and the stopper 25 is positioned at the set value of the first process. When the input key is pressed before the start button is pressed and the process moving key is operated, the process shifts to the next or previous process.

In short, in this example, by turning on, blinking, or turning off the LED lamp with the switch or the LED lamp, it is possible to guide one operation after another, and to easily perform one-step input and input to the program.

The parameter setting method is to press the decimal point key while pressing the input key when the “dimension (memory)” button is blinking. Then, a blank is displayed on the program number display, a parameter number is displayed on the process number display, and a parameter value is displayed on the set value display. Pressing the decimal point key while pressing the input key again displays the process number set value in the program number before the parameter screen is displayed.

When returning from the parameter mode, it is not necessary for the dimension (memory) button to be blinking, and it is possible to return by pressing the decimal point key while pressing the input key at any time.

In this example, a push button or a key switch for mode switching is eliminated, and the operation system switches to the mode when a button belonging to the mode is pressed in principle. That is, for example, when it is desired to manually move the stopper 25, the user manually presses a button for moving in the plus (+) direction or a button for moving in the minus (-) direction.
Immediately, the stopper 25 moves manually. If the conditions for performing the automatic operation are satisfied by directly pressing the start button, the stopper 25 can automatically operate and perform the positioning. When the user wants to input data, the user enters the storage mode by pressing a program button or the like.

Further, the operation can be performed extremely smoothly, for example, the mode can be shifted to the storage mode by a program button, and the process can be edited.

The present invention is not limited to the above embodiments, but can be implemented in an appropriate mode by making appropriate design changes.

[Effects of the Invention] As described above, the present invention is an operation control device for a processing machine as described in the claims, so that the number of operation switches is reduced and operability is good.
