Abstract

A laser processing machine includes a work head, a plate-like work working table for processing a plate-like work, a rod-like work working table including a rod-like work holder for processing a rod-like work, and a work area in which the work head is movably provided. The plate-like work working table is provided movably from one side of the work area into the work area. The rod-like work working table is provided movably from another side of the work area into the work area that is opposite side of the one side. According to the laser processing machine, when switching over between a processing of a plate-like work and a processing of a rod-like work, it is needed only to move/evacuate the plate-like work working table and the rod-like work working table to/from the work area, so that the switching-over operation can be easily done.

First claim

The invention claimed is:

1. A laser processing machine comprising:
a work head;
a plate-like work working table for processing a plate-like work;
a rod-like work working table including a rod-like work holder for processing a rod-like work; and
a work area in which the work head is movably provided, wherein
the plate-like work working table is provided movably from one side of the work area into the work area, and
the rod-like work working table is provided movably from another side of the work area into the work area, the other side being opposite side of the one side.

2. The laser processing machine according to claim 1 , wherein
the rod-like work holder is provided with a rod-like work insertion hole into which the rod-like work can be inserted along a movable direction of the rod-like work working table.

3. The laser processing machine according to claim 1 or 2 , wherein
the rod-like work holder includes a first holder for holding the rod-like work, and a second holder movable on the rod-like work working table along a movable direction of the rod-like work working table.

4. The laser processing machine according to claim 3 , wherein
the second holder is configured to be movable integrally with the work head along the movable direction.

5. The laser processing machine according to claim 1 , wherein
the work head is supported by a head support portion movable along a movable direction of the rod-like work working table, and
the rod-like work working table is configured to be coupled with the head support portion, and is moved by a drive source of the head support portion when moved along the movable direction in a state where coupled with the head support portion.

6. The laser processing machine according to claim 1 , wherein
the plate-like work working table includes a carrying-out/in support plate for carrying-out/in the rod-like work from/to the rod-like work working table located at the work area.

7. The laser processing machine according to claim 3 , wherein
the first holder is configured to hold the rod-like work fixedly and be rotatable together with the rod-like work held fixedly, and
the second holder is configured to hold the rod-like work slidably in the movable direction.

8. The laser processing machine according to claim 7 , wherein
the second holder includes a first roller group including two rollers that are oppositely disposed so that a distance to each other can be changed, and a second roller group including two rollers that are oppositely disposed so that a distance to each other can be changed, and
an opposite direction of the rollers of the first roller group and an opposite direction of the rollers of the second roller group are perpendicular to each other.

9. A laser processing method, wherein
a plate-like work working table is provided movably from one side of an work area in which a work head is provided into the work area, and
a rod-like work working table including a rod-like work holder is provided movably from another side of the work area into the work area, the other side being opposite side of the one side,
the method comprising;
when processing a rod-like work, evacuating the plate-like work working table outside the work area, and moving the rod-like work working table to the work area,
carrying-in the rod-like work on the rod-like work working table moved to the work area,
processing the rod-like work on the rod-like work working table, and
carrying-out the processed rod-like work to a carrying-out/in support plate placed on the plate-like work working table.

10. The laser processing method according to claim 9 , wherein,
when processing a plate-like work, evacuating the rod-like work working table outside the work area, and moving the plate-like work working table to the work area,
carrying-in the plate-like work on the plate-like work working table moved to the work area, and
processing the plate-like work on the plate-like work working table.
