Axis positioning.

The operator installs the unworked work 3 on the vertical support plate 16 of the work cradle, abuts against the X-axis positioning 21 and the Y-axis positioning 22 and fixes it with the handle 19. After the processing is completed, the work piece 3 is released by loosening the handle 19.

Next, a work transfer device for supplying a work to the laser beam machine will be described. FIG. 26 is provided separately for supplying the work to the work transfer device shown in FIG. 21 for supplying the work to the laser beam machine. A suction pad unit 23 is fixed to the suction pad fixing frame 24. This suction pad fixing frame 24
Is fixed to a Z support plate 25 that can move vertically and horizontally, and is vertically guided by an LM guide 26, and the LM guide 26 is fixed to a slide frame 27. The slide frame 27 is guided by the upper guide 30 and the lower guide by the upper and lower guide rollers 28, the upper left and right rollers 29a, and the lower left and right rollers 29b, and runs left and right. For left and right traveling, the left and right racks 33a are fixed to the corner guide 32 and traveled by the traveling motor 34 and the pinion 35.

The work transfer device having the structure shown in FIG. 26 is combined with a laser beam machine to suck the work 3 by the suction pad unit 23 and automatically carry it in and out.

[0017]

In the conventional work transfer apparatus as described above, (1) the processed work 3 is always on the upper shelf 8 of the work cradle A2 and always on the lower tier of the work cradle B5. When the work 3 after processing is carried into the upper shelf 8, the scraps, spatters, etc. of the processed work 3 should drop onto the work 3 before processing on the lower shelf 7 because the work 3 is alternately carried in and out. Therefore, there are problems such as defective machining of the work 3 and failure of the laser beam machine 4.

(2) Since it is necessary to operate the loading / unloading mechanism 10 and the up-and-down mechanism 6 every time the work 3 is loaded / unloaded, the laser processing must be stopped, which may be a factor of alienation of automation. there were.

In the conventional work cradle as described above, since the pitches of the supporting grooves 17 of the lateral supporting plate A13 and the lateral supporting plate B14 are shifted and fixed, the vertical supporting plate 16 is supported by the lateral supporting plate A13 and the lateral supporting plate A13. When inserting and fixing in the support groove 17 of the plate B14, there is a problem that the vertical supporting plate 16 must be manually bent and inserted and assembled, which requires a lot of assembly man-hours and requires a lot of labor by the operator. . Also,
When the laser processing operation is performed on the vertical support plate 16, the tip of the vertical support plate 16 may be sagged or welded, so that the vertical support plate 16 needs to be replaced appropriately. In addition to attachment and removal, the vertical support plate 16 has a spring action, so the vertical support plate 16 must be replaced. The work was dangerous.

In the apparatus for positioning, fixing and releasing the work shown in FIGS. 24 and 25 as described above, the positioning, the work fixing and the releasing can be performed by the external setup, but the work 3 can be completely carried in and out. It was impossible to do such automation.

Further, in the work transfer system shown in FIG. 26, since the material of the work 3 is sucked by the suction pad unit 23, the product after the laser processing is completed, the mounting position and the number of the suction pad units 23 depending on the shape to be processed. However, there is a problem that suction cannot be performed well when the machining groove of the product is located at the suction pad unit 23.

Also in the case of using the magnet unit 36, the same problem as in the above-mentioned suction pad unit 23 and the problem that non-metal materials such as aluminum, copper and stainless steel that cannot be attracted by the magnet cannot be conveyed and are limited to the material of the work. There is.
