DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of the present invention, and FIG. 1 is a diagram showing the schematic structure of the device of the present invention. This automatic fusing device
The bogie (3) is mounted on the pair of left and right guide rails (2) arranged so as to sandwich the cutting surface plate (1) so that the bogie (3) can reciprocate, and the left and right bogies (3) )
(4) is mounted and the fusing torch support member is attached to the garter member (4).
(5) is arranged so that it can run, and the fusing torch support member
The fusing torch (6) is supported on (5) so that it can be moved up and down, and the movement of the carriage (3), the fusing torch support member (5), and the fusing torch (6) is controlled by the traveling control device (7). The configured cutting device, and the linear scanner (8) arranged on the garter member (4) so as to cover the entire width of the cutting surface plate (1),
Image processing arithmetic unit (10) for processing scan data from the linear scanner (8) into graphic data that can be displayed on the display unit (9).
And a storage device (11) for storing the data of the cut parts in advance,
And a scanning mechanism including a processing device (12) for correcting the cut part data.

In the linear scanner (8), a plurality of CCD cameras are arranged in a line and arranged on the garter member (4) of the cutting device, so that the movement of the garter member (4) causes the entire length of the cutting surface plate (1). So that it can be scanned. The image signal from each CCD camera is input to the image processing arithmetic unit (10) and converted into image data with the cutting surface plate (1) as one screen, and this image data is sent to the display unit (9).

The display device (9) displays the shape of the carried-in steel material detected by the linear scanner (8) and also displays a storage device.
The graphic data stored in advance in (11) is called up and displayed by superimposing it on the shape of the incoming steel material. At this time,
If the steel material carried into the cutting surface plate (1) is scrap,
Since the external shape of the carried-in steel material is various,
The information obtained by scanning the placed steel material with a scanner is kept as it is, and the memory figure (cutting part shape) is stored for the steel material figure.
By rotating and moving to display, nesting is performed on the incoming steel material corresponding figure. By doing so, the parts can be arranged according to the actual shape. Then, the displacement amount of the stored figure at the time of this nesting is input to the data correction processing device (12), the cutting data of the part is corrected by the data correction processing device (12), and the corrected cutting data of the cutting device is input. It is sent to the traveling control device (7) and parts are cut out from the incoming steel material based on the corrected cutting data.

In the above-mentioned embodiment, the non-shaped steel material called "mill ends" was explained in mind as the carried-in steel material. However, even if the shaped steel material is called a standard length material, the standard X- of the cutting surface plate (1) is used. Since it is extremely difficult to place the incoming steel material in line with the Y axis, the figure of the cut part is displaced on the display device, and the cut data is corrected based on this displaced position. It is possible to accurately cut out and improve nesting efficiency.

Further, even in the case where the irregularly shaped part is groove-processed, the original machining pattern is rotated so that the predetermined pattern is superposed on the posture of the steel material that has been carried in, and the machining data is corrected. By processing, accurate groove processing can be performed at an accurate position. further,
It is also possible to inspect the cut-out parts by rescanning the cut-out steel material and overlapping it with the original figure.

In the above-mentioned embodiment, the linear scanner (8) has been described as the device arranged on the garter member (4) of the fusing device, but as shown in FIG. Separately, a carriage is arranged, and a linear scanner (8) is arranged on this carriage so as to be movable in the moving direction of the garter member (4) above the cutting surface plate (1).
You may make it comprise so that (8) may evacuate from an operation area. If the support mechanism of the linear scanner (8) is configured separately from the fusing device, the linear scanner (8) is less likely to be affected by gas and heat at the time of cutting, and the detection accuracy can be kept high for a long period of time. You can do it.

As the fusing device, an NC control type automatic fusing device such as a gas fusing device or a plasma fusing device can be used.
