- the work holder 40 can hold the end portion of the plate member P where the undulation is generated at a predetermined position (first predetermined position or second predetermined position). In position.
- the position of the end portion of the plate material P is set to a predetermined position (first predetermined position or second predetermined position) above the plate material P in the vertical direction.
- the laser nozzle 31 of the laser irradiation unit 30 can be prevented from colliding with the edge of the plate material P when the laser irradiation unit 30 is moved from directly above the plate material P to directly above.
- the workpiece holder 40 is disposed closer to the laser irradiation unit 30 than the first workpiece holder 41 and the first workpiece holder 41, and has a second clearance smaller than that of the first workpiece holder 41. And a work holder 42.
- FIG. 4 is a front view showing the laser irradiation unit 30 and the work holder 40A of the laser processing apparatus 1A according to the second embodiment of the present invention.
- the first work holder 41A constituting the work holder 40A does not have the cap 414. For this reason, the plurality of hairs are not bundled similarly to the second work holder 42. With this configuration, the first workpiece holder 41 can be easily manufactured, and the configuration of the first workpiece holder 41A can be simplified.
- each part of the laser processing apparatus is not limited to the configuration of each part of the laser processing apparatus in the present embodiment.
- the laser irradiation unit, the drive unit, the workpiece holder, the plate material conveying device, the leveler device, and the like are configured in the laser irradiation unit 30, the driving unit 60, the workpiece holder 40, the plate material conveying device 20, and the leveler device 10 in this embodiment. It is not limited to such a configuration.

Abstract
Description
図1は、本発明の第一実施形態に係るレーザー加工装置1を示す側方概略図である。図2は、本発明の第一実施形態に係るレーザー加工装置1のレーザー照射部30及びワーク保持具40が移動している様子を示す正面図である。図3は、本発明の第一実施形態に係るレーザー加工装置1のレーザー照射部30が板材Pの直上部外に移動した様子を示す平面図である。
レーザー加工方法では、先ず、コイル材Cから送り出され平坦に延ばされて、レベラ装置10によってくせ取りが行われた板材Pが、レーザー照射部30の位置に至るまで送り出される。次に、駆動部60によりレーザー照射部30、ワーク保持具40、及び、支持部材62を、主にX軸レール61に沿った方向へ移動させて、レーザー照射部30を板材Pの直上で移動させる。この際、ワーク保持具40の第2ワーク保持具42のブラシ部421の複数の毛の下端部は、板材Pの上面に当接し、鉛直方向において、第2ワーク保持具42は、レーザー照射部30のレーザーノズル31の下端と板材Pとの距離が、第2所定の値の範囲内で離間する状態となる第2所定位置に、板材Pを保持する。この状態を維持したまま、駆動部60によりレーザー照射部30、ワーク保持具40、及び、支持部材62を主にX軸レール61に沿った方向へ移動させながら、レーザー照射部30のレーザーノズル31から板材Pに対してレーザーを照射して、板材Pを切断してゆく。この際、ワーク保持具40の第2ワーク保持具42のブラシ部421の複数の毛の下端部は、板材Pの上面に当接しておらず、板材Pの上面から離間している。
本実施形態では、レーザー加工方法において、板材Pをレーザー照射することにより切断する。レーザー加工方法は、板材Pの直上部外にレーザー照射部30があるときに板材Pの端部の位置を所定位置に保持する板材端部保持工程と、レーザー照射部30が板材Pの直上部外から直上に移動するレーザー照射部移動工程と、を有する。
