On the other hand, on the right side of the machine 2 in Figure 1 is a workpiece conveyor 12.
A conveyor member 12a, such as a belt, is supported on the workpiece conveyor 12 so as to be movable in the direction of the arrow, that is, in the direction away from the machine body 2.

Since the laser processing machine 1 has the above-described configuration, as shown in FIG.
When cutting out the workpiece 13, the workpiece 13 to be machined is first mounted on the workpiece mounting surface 3a of the table 3, and in this state, the table 3 is moved in the direction of arrow A=B by the laser processing head 7.
is suitably moved in the directions of arrows C and D, and further, 1--chi 9 is suitably moved in the directions of arrows E and F. In this way, the torch 9 is connected to the workpiece 13.
When the laser processing head 7 is positioned at the predetermined processing start position above, a laser beam is supplied from a laser oscillator (not shown) to the laser processing head 7, and the beam is emitted from the torch 9 toward the workpiece 13 on the table 3. Assis 1-
The small workpiece 13a is cut out together with the gas.

Note that during laser processing, the arm 10 and cylinder 11 are not driven, and the electromagnet 11b attached to the tip of the piston rod lla is neither protruded nor excited. In addition, the electromagnet 11
Since the lower surface 11c in FIG. 1b of FIG. Therefore, during laser processing, the electromagnet 11b and the workpiece 1

After cutting out one or more small workpieces 13 in this way, in order to carry out the cutout small workpieces 13a out of the machine body 2 of the laser processing machine 1, as shown in FIG. And while the cut-out small workpiece 13a remains mounted on the workpiece mounting surface 3a, the torch 9
is moved in the direction of arrow E in the figure so that the tip of the torch 9 is positioned a predetermined distance above the surface of the workpiece 13 in the figure.

When the tip of the torch 9 is located a predetermined distance above the surface of the workpiece 13, the table 3 is moved again in the directions of arrows A and B, and the laser processing head 7 is moved in the directions of arrows C and D as appropriate, and the piston of the cylinder 11 is moved. The electromagnet 11b attached to the rod lla is a small workpiece 13 cut out.
It is positioned so that it is located approximately at the center of the surface in the figure a (see FIG. 3).

An electromagnet 1 is placed approximately at the center of the surface of the small workpiece 13a in the figure.
1b is located, as shown in FIG. 4, the cylinder 11 is driven by air pressure or the like to move the piston rod

The cylinder 11 is driven again by air pressure, etc., and the electromagnet 1
1b is raised and retreated together with the piston rod 11a in the direction of arrow E in the figure. Then, the iJs object work 13a that is attracted to the electromagnet 11b moves in the E direction with the movement of the electromagnet 11b in the E direction, and separates from the work 13.

When the small workpiece 13a is removed from the workpiece 13, the rod lla is further moved in the E direction to remove the small workpiece 1.
3a is raised to a position higher than the surface of the conveying member 12a of the work conveyor 12 in FIG. In addition,
At this time, approximately the center of the surface of the small workpiece 13a is the electromagnet 1.
Since the small workpiece 13a is attracted to the lower surface of 1b,
will not lose its weight balance and fall away from the lower surface 11c.

When the small workpiece 13a has risen to a position higher than either the workpiece 13 or the workpiece conveyor 12, etc., the sixth
As shown in the figure, the laser processing head 7 is driven to move a predetermined distance in the direction of the arrow.

In addition, at this time, the tips 9a of 1 to 9 and the small workpiece 1
3a are each located a predetermined distance above the surface of the workpiece 13, so that they do not interfere with the workpiece 13 or other parts of the laser processing machine 1, and the laser processing head 7 moves in the direction of the arrow. The movement is smooth.

When the small object=8-work 13a is located at a predetermined position on the workpiece conveying member 12a, the cylinder 11 is driven to project the electromagnet 11b together with the piston rod lla in the direction of arrow F, as shown in FIG. Electromagnet 11
The small workpiece 13a attracted to b is transferred to the workpiece conveying member 12.
close to the surface of a.

When the small workpiece 13a comes close to the surface of the workpiece conveying member 12a, when the electromagnet 11b is demagnetized to eliminate the magnetic force, the small workpiece 13a, which had been attracted to the lower surface 11c of the electromagnet 11b, loses its adsorption force and loses its own weight. As a result, the workpiece leaves the lower surface lie and falls to a predetermined position on the workpiece conveying member 12a, as shown in FIG. Workpiece conveyance member 12a
The small workpiece 13a that has fallen to a predetermined position above is carried out to a machine or the like where the next processing step will be performed by the workpiece conveyance member 12a, which is driven to move in the direction of the arrow.

When the carrying out process of the small workpiece 1.3a is completed, the arm 10, cylinder 11,

Furthermore, it is of course possible to control the series of operations described above using an NC program. Furthermore, in this embodiment, an electromagnet 1 is used as an adsorption member attached to the tip of the cylinder 11.
As mentioned above, the adsorption member is the electromagnet 1
It goes without saying that the method is not limited to 1b, but may also be one that utilizes vacuum suction using pneumatic pressure. When an attraction member that utilizes vacuum suction or the like using air pressure is attached, it is convenient because the workpiece 13 can be made of a non-magnetic material that does not have the property of being attracted to a magnet. Note that the handling device is not limited to the suction function, but is equipped with an appropriate workpiece gripping means, and if there is an appropriate space around the small workpiece, it can grip the small workpiece from above and below or from the left and right sides. It is also possible to carry out the unloading process in the form of
