Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to an NC device, and particularly to an NC machine suitable for processing specific workpieces in large quantities efficiently, such as a dedicated machine tool or a transfer machine.
The present invention relates to a control device.

0002

BACKGROUND OF THE INVENTION Conventionally, NC devices have been characterized by being programmable, and because of this, they have been widely adopted as control devices for general-purpose machines such as machining centers and NC lathes that process many types of workpieces.

For example, as seen in Japanese Utility Model Publication No. 2-3422, the operation panel of an NC device includes a group of keys for inputting and outputting NC programs and data, a group of switches and lamp displays for controlling various devices, and a group of switches for turning on the power. /OFF switch etc. are provided. Workers use this operation panel to create NC programs and perform normal machining operations. Therefore, a certain level of NC knowledge was required.

[0004] However, recently, NCs have been adopted in transfer machines and special-purpose machines, and the control panels have been equipped with keys and displays for entering NC data, requiring extremely complicated operations for workers. It was. However, in transfer machines and special-purpose machines, once the modification and adjustment work of the NC program is completed, keys, selector switches, etc. that were necessary for this are completely unnecessary. Furthermore, for workers who are not familiar with NC, these many keys are not only complicated, but also pose a risk of accidentally changing data in the NC program. Another problem was that in an emergency, necessary button operations were delayed.

On the other hand, in the initial NC adjustment work, since the position of the operation panel installed in the processing machine or each station is far from the position of the tool, it is difficult to check for interference between the tool and jig and check for tool damage. In addition to the operator who performs the operations, an operator who operates the control panel is required.

[0006]

[Object of the Invention] Therefore, an object of the present invention is to clearly distinguish between emergency stop switches for machine operators and keys for software NC adjusters, thereby improving operability for machine operators and NC adjusters. The objective is to improve the performance of the system, prevent erroneous operations, and simplify the operation section.

[0007]

Solution to the Invention In view of the above object, the present invention incorporates only an emergency stop switch and a selector for operation commands necessary for normal machine operation and automatic operation into a normal operation operation panel, and
A key group for data reference and input and a data display section are incorporated into the NC adjustment device, and this NC adjustment device is provided with functions necessary for NC operation.

[0008] Incidentally, the NC adjustment device for the NC adjustment person is constructed as a small device for ease of portability.
It is difficult to incorporate a plurality of emergency stop switches necessary for NC operation, and it is also difficult to simultaneously display display items necessary for NC operation on a small display.

Therefore, the present invention stores a plurality of modes necessary for NC operation and display items for each mode in the built-in memory of the NC device, and in response to a call from the NC adjustment device, the display of the NC adjustment device is It is possible to display them sequentially using a menu in the department.
