Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for simultaneously controlling and managing a plurality of welding machines.

Conventionally, this type of group management method did not exist, and a welding machine control device was attached to each welding machine, and each welding machine was individually controlled and managed.

Therefore, conventionally, when controlling and managing multiple welding machines, it was necessary to operate the welding machines sequentially and to have as many workers as necessary operate each welding machine sequentially. It was hot. That is, there is a drawback that multiple operators and multiple welding machines are required to operate continuously.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and it is a group of welding machines that can control and manage multiple welding machines at the same time by data linking the welding machine control device and the host computer. The purpose is to provide a management method.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of this invention,
In the same figure, 1 is a welding machine, 2 is a plurality of welding machines 1
This is a welding machine control device that controls the 3 is a host computer that controls and manages these plural welding machine control devices. The host computer 3 and the welding machine control device 2 are connected by a data link transmission line 4.

FIG. 2 shows the configuration of the host computer 3 and the welding machine control device 2. Upper computer 3
calculates the welding conditions (arc voltage of the welding machine) from the welding information (material, dimensions, etc. of the workpiece) input from the input device 21 and the man-machine interface 23 to which the input device 21 and display/printing device 22 are connected. There is also a search unit 24 that detects current, welding wire feeding speed, welding torch oscillation rate, etc.).
Welding conditions are stored in welding condition memory 25. Welding condition data 4 sent from the welding machine control device 2 is passed through the data editing section 28 and displayed and recorded on the display and printing device 22. Interfacing between the host computer 3 and the data link transmission path 4 is performed by a data link interface 26. The data link interface 26 is controlled by a data link control section 27.

On the other hand, the welding machine control device 2 is interfaced with a data link transmission path 4 and a data link interface 31. The data link interface 31 is controlled by a data link control section 32. The welding condition setting values received through the data link interface 31 are stored in the data memory 35 and then calculated in the control pattern calculation section 33 and sent to the input/output interface 3.
6 and then the welding machine 1 by the welding control servo mechanism 37.
control.

Raw data of welding conditions from the welding machine 1 is stored in the data memory 35 via the input/output interface 36 and transmitted to the host computer 3 via the data link interface 31.

FIG. 3 shows items of transmission data and control signals between the host computer 3 and the welding machine control device 2, and items of control signals between the welding machine control device 2 and the welding machine 1.

Next, the operation of this embodiment will be explained based on the data link timing diagram between the host computer and each welding machine control device shown in FIG. 4. Note that n welding machine control devices #1 to #n are connected to the host computer 3 via a data link transmission line 4.

That is, when the host computer 3 receives the welding end signal 41 from #1 of the welding machine control device 2, the host computer 3 sends the welding condition setting value 42 to #1, and upon completion of the transmission, sends the welding start command 43 to #1. Send to. Thereafter, unless the host computer 3 receives a welding end signal from the welding machine control devices #1 to #n, the host computer 3 receives the raw data 45 of the welding conditions from the welding machine control devices #1 to #n, and the data After editing, the display and printing device 22 performs display, recording, and other management.

The welding machine control device 2 which has received the welding condition setting values from the host computer 3 starts controlling the welding machine 1 connected to itself after receiving the welding start command from the host computer 3. An example of welding conditions for welding machine control is shown in FIG.

As described above, according to the present invention, a host computer and a plurality of welding machine control devices are connected by a data link transmission path, and the host computer has a database of welding conditions, and the welding conditions are determined based on welding information. Since it is possible to perform online search for welding conditions and perform welding control and group management based on the results, it is possible to control and manage multiple welding machines at the same time without requiring multiple operators for each welding machine. Can be done.
