Nozzle changer and laser processing machine

Abstract

The invention relates to a nozzle changer (1) for receiving a plurality of nozzles and for mounting and / or dismounting nozzles (2) on a processing head (3) of a laser processing machine (4), wherein a plurality of nozzle holders (5) are rotatably arranged in the nozzle changer (1), and the nozzle holders (5) are configured to each receive at least one nozzle (2), wherein the nozzle holders (5) are coupled to one another by means of gear-engaged tooth geometries (6) such that a rotation of one nozzle holder (5) causes a rotation of at least one further nozzle holder (5), preferably a plurality of nozzle holders (5), particularly preferably all further nozzle holders (5) in the nozzle changer (1), and wherein at least one of the nozzle holders (5a) can be driven in both directions of rotation by a motor (7) without the motor (7) being in engagement with the tooth geometry (6) of the driven nozzle holder (5a).
