Patent number: 10086475Abstract: Laser processing machines, such as laser cutting machine, including a work table receiving workpiece, and work arm with a laser cutting head. Laser cutting head includes nozzle receiving device and nozzle. Via nozzle laser beam may be directed onto work piece. Machine includes main drives moving work arm and/or the laser cutting head on X-Y-Z axes to process work piece, as well as an alignment unit to adjust laser beam. An adjusting station includes receiving unit fixing nozzle and/or the nozzle receiving device during centering of nozzle. The alignment unit has head element in laser cutting head. Head element receives nozzle and/or the nozzle receiving device and is slidable in X-Y directions, via the main drives. Head element may be fixed in a selected position, within the laser cutting head, via clamping device releasable during nozzle centering at adjusting station.Type: GrantFiled: February 8, 2018Date of Patent: October 2, 2018Assignee: BYSTRONIC LASER AGInventors: Daniel Cathry, Ernest Imboden, Tobias Bugmann, David Broger, Thierry Perrin

Patent number: 6059221Abstract: The apparatus for receiving and forwarding a reserve lap roll employs a trough to receive the lap roll and pivotally mounted arms for pivoting the trough from the reserve position toward the working position. The arms may be pivoted by a piston and cylinder unit. Alternatively, a parallelogram arrangement of guide rods may be used for moving the trough from the reserve position toward the working position. In still another embodiment, pairs of pivotally mounted arms can be used to move the reserve lap roll from the reserve position directly into the working position. In each embodiment, the pivotal elements are spaced apart a distance greater than the length of an empty tube in the working position so that the empty tube can be ejected through the space between the arms to a position below the reserve position.Type: GrantFiled: March 5, 1996Date of Patent: May 9, 2000Assignee: Rieter Machine Works, Ltd.Inventors: David Broger, Heinz Clement
