A laser processing apparatusincludes: a laser head H; a conveying devicethat conveys a workpiece W; a head driving mechanism that moves the laser head H; a dust collecting boxthat moves below the workpiece W and follows the laser head H such that the dust collecting boxis disposed below the laser head H; an outer support rollerand an inner support rollerthat are provided at an openingof the dust collecting bozand are rotatable around an axis parallel to a width direction orthogonal to a conveying direction Fy; and a counter rollerthat rotates the outer support rollerin synchronization with a conveying operation of the workpiece W by the conveying device. The counter rollertransmits motive power of the conveying deviceas a belt conveyor to the outer support roller

Laser processing apparatus

A laser processing apparatusincludes: a laser head H; a head driving mechanism that moves the laser head H above a workpiece W; and a dust collecting boxthat moves below the workpiece W and follows the laser head H. A non-contact support unitis provided at an openingof the dust collecting box, and the non-contact support unitsuctions a lower surface of the workpiece W toward a suction surfaceand supports the workpiece W without bringing the lower surface of the workpiece W and the suction surfaceinto contact with each other. An outer support rollerand an inner support rollerthat are each rotatable about an axis parallel to a width direction orthogonal or substantially orthogonal to a conveying direction Fy are provided at the opening

Provided are a laser processing method and a laser processing device which prevent a laser irradiation unit from colliding with an edge of a plate material when the laser irradiation unit returns to a portion just above the plate material from an outer part of the portion just above the plate material. The laser processing method for cutting a plate material by laser irradiation, the method including: a plate material end portion holding process of holding a position of an end portion of the plate material at a predetermined position when a laser irradiation unit is present outside a portion just above the plate material; and a laser irradiation unit moving process in which the laser irradiation unit moves from an outer part of the portion just above the plate material to the portion just above the plate material.

Laser processing method and laser processing device

A workpiece support apparatus is provided with a plurality of support members. The support members support a workpiece. Each support member moves along a moving path to a machining position while the support member is held at a first holding position for supporting the workpiece or a second holding position which is spaced apart from the first holding position. At least one support member is displaced from the first holding position to the second holding position or from the second holding position to the first holding position along a machining trajectory, before the support member arrives at the machining position whenever each support member is moved to the machining position.

Workpiece support apparatus

A laser machining apparatus is provided with: a workpiece support unit; a machining head; and a machining head moving unit. The workpiece support unit includes: an end support part that supports a width end of a workpiece; and an inside support part that supports an inside portion of the workpiece in a width direction. The end support part is movable in a longitudinal direction independently from the inside support part in response to a movement of the machining head.

Laser machining apparatus

A conveyor system is provided with a plurality of support members which are erected and spaced apart from each other, a plurality of holding units on which the plurality of support members are held, and a drive unit that moves the holding units in a conveying direction. A supporting plane on which a workpiece is supported and conveyed is formed by distal end portions of the support members. The support members are movable in parallel with respect to the supporting plane.

Conveyor system

A panel inspection apparatus includes a resonant frequency extracting unit for extracting a plurality of resonant frequencies of a panel, a resonant frequency selecting unit for selecting a combination of resonant frequencies consisting of two resonant frequencies A and B with different vibration propagation paths among the extracted plurality of resonant frequencies, a non-defective range generating unit for generating a non-defective range on a coordinate system in which resonant frequencies A and B are taken on coordinate axes by statistically processing a set of the resonant frequencies A and B selected for each of a plurality of non-defective panels determined as non-defective in advance, and a panel quality determining unit for determining whether the quality of the panel to be inspected is good based on comparison between resonant frequencies A and B selected for the panel to be inspected and the non-defective range generated by the non-defective range generating unit.
