  FIG. 5 is a flowchart of the operation control operation by the operation control system shown in FIG. 4, and FIG. 6 is an explanatory diagram of the operation control operation by the operation control system shown in FIG.

  First, in step 101 of FIG. 5, before the machining operation mode starts, the position of the simple operation control panel 11 for each bending process of the machining operation is registered.

  That is, since the operator's standing position is predicted in advance for each bending step of the machining operation to be performed, the position of the simple operation control panel 11 that is easy to operate at the operator's standing position based on the operator's standing position. Servo control is set so that the simple operation control panel 11 moves.

  The setting of the servo control is performed by the operator via the input display unit 18 of the operation control board 9, and the CPU 17 of the operation control board 9 sends the servo control setting to the CPU 29 of the simple operation control board 11 and the Ethan device. The CPU 29 of the simple operation control board 11 controls the motor 13d of the belt transport mechanism 13 based on the setting of the servo control, and moves the simple operation control board 11 to the set position.

  Next, in step 103, when the machining operation mode is set, the operation shifts to the bending operation of the workpiece W based on the control of the CPU 17 of the operation control panel 9.

  Here, the CPU 17 of the operation control panel 9 uses punch and die data, product shape data, and workpiece material (work W) data in the database 19 in accordance with settings and instructions from the operator via the input display unit 11. At the same time, an input and set bending operation is performed using the RAM 15 in accordance with a computer program from the ROM 14.

  In step 105, each time the process moves to each bending step, the CPU 29 of the simple operation control board 11 is set at the position of the simple operation control board 11 which is set as described above and is easy to operate at the standing position of the operator. The simple operation control panel 11 is moved by the control.

  That is, the CPU 29 recognizes the current position of the simple operation control board 11 based on the information from the rotary encoder 13e, and the simple operation control board 11 moves to the position of the simple operation control board 11 set as described above. The motor 13d is controlled as follows.

  As described above, the simple operation control panel 11 is moved to a position where the operator can easily operate at the standing position set as described above for each bending step of the machining operation. Even when the operator who is working from the panel 9 is far away, the operator can easily confirm the shape and orientation G of the workpiece W in the bending process and adjust operations such as stroke adjustment via the simple operation control panel 11. Will be able to do.

  Further, as shown in FIG. 6, the simple operation control panel 11 is provided with a display unit 11a, and the display unit 11a displays the shape and orientation G of the workpiece W to be bent. Therefore, the operator confirms the shape and orientation G of the workpiece W actually carried in while referring to the shape and orientation G of the workpiece W displayed on the simple operation control panel 11 at hand. Can do.

  Here, when the simple operation control panel 11 is moved to a preset position in a certain bending process, the simple operation control panel 11 is difficult to operate or obstructs depending on how the operator works. May be frustrated.

  Therefore, in step 107, it is determined by the operator whether or not the setting position of the simple operation control panel 11 needs to be corrected.

  When it is necessary to correct the setting position of the simple operation control panel 11 in step 107, the position of the simple operation control board 11 is corrected in step 109.

  That is, when the simple operation control panel 11 is difficult to operate or gets in the way depending on how the operator works, the operator presses the slide switches 11d and 11e on the left or right side of the simple operation control panel 11, The slide mechanism of the simple operation control panel 11 is operated, the simple operation control board 11 is slid rightward or leftward, and the position of the simple operation control board 11 is corrected to the position where it is most easily operated.

  That is, for example, when the simple operation control panel 11 is slid and moved in the right direction by a predetermined distance, the operator first presses the left slide switch 11d while pressing the enable switch 11f. When the left slide switch 11d is pressed, the CPU 29 sends a clockwise drive signal to the motor 13d by a signal from the enable switch 11f and the left slide switch 11d, whereby the motor 13d rotates clockwise. When the belt 13a is rotated clockwise, the simple operation control panel 11 is moved in the right direction and the slide switch 11d is released, the rotation of the motor 13d is stopped, and the movement of the simple operation control board 11 is also stopped.

  As a result, the set position of the simple operation control panel 11 is corrected, which makes it easier for the operator to operate the simple operation control board 11.

  Next, in step 111, correction of the setting position of the simple operation control panel 11 is registered.

  That is, the CPU 17 of the operation control panel 9 recognizes the current position of the simplified operation control panel 11 after the position correction based on information from the rotary encoder 13e, and updates the set position information with the corrected position information.

  As a result, the setting position of the simple operation control panel 11 is updated, so that when the same processing is performed, the simple operation control board 11 can be automatically moved to the correction position.

  Next, in step 113, the stroke adjustment by the simple operation control panel 11 after the bending process is performed by the operator.

  That is, here, as shown in FIG. 3, the angle measuring device 12 provided in the simple operation control panel 11 measures the angle of the bent workpiece W, and the measured angle is determined by infrared communication by infrared communication. The CPU 29 of the simplified operation control panel 11 controls the display unit 11a to display the measurement angle and the target angle.

  Thereby, the operator refers to the measurement angle and the target angle displayed on the display unit 11a, operates the stroke adjustment unit (wheel) 11b, and adjusts the stroke of the punch 7b by the operation. That is, the CPU 29 of the simple operation control panel 11 sends the stroke adjustment value input via the stroke adjustment unit 11 b to the CPU 17 of the operation control panel 9 via the Ethan devices 20 and 31, and the CPU 17 of the operation control panel 9. Adjusts the stroke of the punch 7b via the driver 23 based on the stroke adjustment value.

  The stroke adjustment value is registered in storage means such as the RAM 15 in association with the bending process, and is used at the same bending process.

  As described above, in this embodiment, the simple operation control panel 11 is moved to a position where it can be easily operated at the standing position of the operator for each bending step of the machining operation. Even in a far position, the operator can easily perform adjustment operations such as confirmation of the shape and orientation G of the workpiece W in bend machining and stroke adjustment via the simple operation control panel 11.

  Since the position of the simple operation control panel 11 can be further corrected after the automatic operation control panel 11 is automatically adjusted, the simple operation control panel 11 may be difficult to operate depending on how the operator works. Even if it gets in the way, the operator can move the simplified operation control panel 11 to a position where it can be operated more easily.

  The present invention is not limited to the embodiment of the invention described above, and can be implemented in other modes by making appropriate modifications as follows.

  In the above-described embodiment, the measurement angle and the target angle measured by the angle measuring device 12 are displayed on the display unit 11a of the simple operation control panel 11. However, the difference angle between the measurement angle and the target angle is displayed. Alternatively, the angle of the difference may be displayed or sent to the CPU 17 of the operation control board 9 via the Ethan devices 20 and 31 so that the CPU 17 of the operation control board 9 automatically controls the stroke adjustment.
