Laser processing machines
A laser processing machine includes a workpiece support, a movement unit that is movable relative to the workpiece support, the movement unit being configured to move a laser processing head over the workpiece support, and a switch cabinet in which one or more control components of the laser processing machine are provided. An arrangement of the switch cabinet provides a free movement space disposed underneath at least a portion of the switch cabinet, wherein at least a portion of the movement unit is disposed within the free movement space.
1. A laser processing machine, comprising:
a workpiece support;
a movement unit comprising a transverse carrier that extends above and across the workpiece support and a line guiding device provided as an energy guide chain that is movably coupled to the transverse carrier;
a laser processing head that is movably coupled to the transverse carrier such that the laser processing head can be guided along the transverse carrier in a longitudinal direction thereof;
a bearing structure that extends along at least one side of the workpiece support and perpendicularly relative to the transverse carrier, the bearing structure supporting the transverse carrier such that the transverse carrier, together with the laser processing head, can move along the bearing structure and along the workpiece support; and
a switch cabinet in which one or more control components of the laser processing machine are provided,
wherein the transverse carrier and the bearing structure are disposed below the switch cabinet, and
wherein the switch cabinet provides a free movement space disposed thereunderneath and above the transverse carrier and the bearing structure, such that at least a portion of the transverse carrier and at least a portion of the bearing structure are disposed within the free movement space, and such that the transverse carrier is movable within the free movement space along the bearing structure and along the workpiece support, and wherein at least a portion of the line guiding device is disposed within the free movement space.
2. The laser processing machine according to claim 1 , wherein the bearing structure separates at least a portion of the free movement space from an operating space of the laser processing machine extending over the workpiece support.
3. The laser processing machine according to claim 1 , wherein the switch cabinet forms a portion of a side wall of the laser processing machine.
4. The laser processing machine according to claim 3 , further comprising an enclosure that includes the side wall, and wherein the switch cabinet forms a portion of the enclosure.
5. The laser processing machine according to claim 1 , wherein the switch cabinet comprises a carrier platform.
6. The laser processing machine according to claim 5 , wherein the bearing structure is supported on a floor of the laser processing machine, and wherein the carrier platform is supported on the floor independently from the bearing structure.
7. The laser processing machine according to claim 5 , wherein the bearing structure is supported on a floor of the laser processing machine, and wherein the carrier platform is supportable on the floor independently from or by the bearing structure.
8. The laser processing machine according to claim 5 , wherein the carrier platform is supported on a floor of the laser processing machine by at least two support arrangements that define at least a portion of the free movement space.
9. The laser processing machine according to claim 5 , wherein the carrier platform comprises at least one cable duct and/or at least one ventilation duct.
10. The laser processing machine according to claim 9 , wherein the carrier platform comprises at least one ventilation duct through which an inner space of the switch cabinet can be supplied with cooling air via supply openings.
11. The laser processing machine according to claim 10 , wherein the supply openings are nozzle-shaped.
12. The laser processing machine according to claim 10 , further comprising a controllable actuation drive that is operable to open and close the supply openings individually.
13. The laser processing machine according to claim 5 , wherein the carrier platform comprises a plurality of longitudinal struts, and wherein at least one of the longitudinal struts forms a partition wall between two longitudinal channels of the carrier platform.
14. The laser processing machine according to claim 5 , wherein the carrier platform comprises at least one profile member that extends in a longitudinal direction of the switch cabinet, and wherein at least one longitudinal surface portion of the profile member forms a longitudinal strut that acts as a partition wall between two longitudinal channels of the carrier platform.
15. The laser processing machine according to claim 14 , wherein the longitudinal strut formed by the at least one longitudinal surface portion of the profile member is configured to stiffen the carrier platform.
16. The laser processing machine according to claim 1 , wherein the transverse carrier is formed as an extension arm.
