Abstract
Official abstract text for this publication.
The present disclosure relates to a suction device configured for a laser processing machine with a laser processing head which can be moved over a workpiece holder, with a fan and several flaps which are to be opened selectively to generate an air flow and which are in communication with the fan, and with a control configured to detect the position and operating state of the laser processing head and to control the flaps as a function of the detected position and the operating state of the laser processing head.
First claim
Opening claim text (preview).
The invention claimed is: 1. A laser processing machine with a laser processing head which is moved in a processing space over a workpiece holder, the laser processing machine comprising: at least one air supply opening for supplying air into a chamber, a fan and several flaps for exhausting air from the chamber which are to be opened selectively in order to generate an air flow and which are in communication with the fan, a control configured to detect a future position of the laser processing head and to control the flaps as a function of the detected position of the laser processing head, and wherein the control is configured to detect the operating state of the laser processing head and to control the flaps as a function of the future position and the operating state of the laser processing head corresponding to the future position, and wherein the flaps open before the start of the processing operating statem, in the region of the process operating state for an optimum air flow or a volume flow, wherein the control is further configured to determine a future position and the operating state of the laser processing head corresponding to this position on the basis of a processing plan, and wherein the processing space is further configured to receive a workpiece to be machined. 2. The laser processing machine according to claim 1 , further comprising: at least one sensor configured to detect contamination of air in the processing space, and wherein the control is further configured to use sensor data of the sensor for controlling the flaps. 3. The laser processing machine according to claim 2 , wherein the control is configured to control an opening of a protection door of the processing space as a function of the sensor data. 4. The laser processing machine according to claim 2 wherein the control is further configured to use the sensor data for determining a maintenance state of the laser processing machine. 5. The laser processing machine according to claim 2 , wherein the control is further configured to control a suction volume of the fan as a function of the sensor data. 6. The laser processing machine according to claim 4 , wherein the flaps are arranged in at least one of a lower region of the processing space, an upper region, and a central region. 7. The laser processing machine according to claim 1 , wherein the laser processing machine is a laser cutting machine. 8. The laser processing machine according to claim 1 , wherein the laser processing head is a laser cutting head.
