A method for separating blanks includes continuous conveying of a sheet metal strip in a transport direction to a laser cutting station, concurrent cutting of the sheet metal strip by at least one cutting laser, wherein a cut sheet metal strip is formed from successive sections of the same cutting geometry, transporting the cut sheet metal strip on a first conveyor belt in the transport direction, taking over the cut sheet metal strip from the first conveyor belt, transporting the cut sheet metal strip in the transport direction, separately ejecting the at least one residual blank of each section, transporting the at least one blank of each section into overlap with a second conveyor belt and ejecting the at least one blank from the suction conveyor, and transporting the blanks ejected one after the other from the suction conveyor horizontally in the transport direction to a collecting station.

Method and apparatus for separating blanks

The invention relates to a method for cutting a sheet metal blank from a sheet metal strip () continuously conveyed in a transport direction (T), by means of at least one laser cutting device (), having the following steps:

A method and a device for producing bipolar plates for fuel cells. A bipolar plate is formed by joining an anode plate to a cathode plate, wherein the anode plate and the cathode plate are formed by forming a substrate plate. In order to provide a cost-effective and automated method, it is proposed that a plate already provided with a reactive coating or catalyst coating, which is transported, automatically driven, via a transport device from the forming device to the joining device, is used as substrate plate.

In a method for setting bending of at least one straightening roller in a roller straightening machine, the straightening roller is supported by a plurality of supporting roller devices arranged beside one another in the axial direction, wherein each supporting roller device can be adjusted by an actuating device such that stresses are produced in the straightening roller. To control the actuating device, a control system is provided, by which the adjustment of the supporting roller device can be set manually. Limiting values (vMA, vMI) with respect to the stresses produced in the straightening roller are stored in the control system. In the event of adjustment of one of the supporting roller devices, maxima (MA) and minima (MI) of the stresses produced in the straightening roller are calculated and it is checked whether the maxima (MA) and minima (MI) lie within the limiting values (vMA, vMI).

A device for cutting sheet metal plates out of a sheet metal strip includes a laser cutting device moving back and forth in a transport direction of the sheet metal strip and a y-direction running perpendicular to the transport direction, a first conveyor belt having first end moving back and forth together with the laser cutting device in the transport direction, a second conveyor belt having a second end opposite the first end and moving back and forth in the transport direction. The first and second ends are moved such that a laser beam generated by the laser cutting device is directed towards a gap formed between the first and second ends and extending in the y-direction. In order to avoid adhesions to an underside of the sheet metal strip, at least one support strip and/or the dust discharge shaft is provided with a ventilation device for ventilating the gap.

Device for cutting sheet metal plates out of a sheet metal strip

An apparatus for cutting metal plates out of a metal strip includes a laser cutting apparatus that is movable back and forth in a transport direction of the metal strip, and a support device for supporting the metal strip to be cut. The support device includes a first support device having a first support strip and a second support device having a second support strip located opposite the first support strip, wherein the first and the second support strip are moved concurrently with the laser cutting apparatus such that a laser beam of the laser cutting apparatus is always oriented towards a gap formed between the first and the second support strip. A dust discharging device is arranged downstream of the support strips in a discharging direction directed away from the laser cutting apparatus. The support strip and/or the dust discharge shaft includes a ventilation device for ventilating the gap.

The invention relates to a method for correcting a predetermined cutting path for cutting a metal blank from a metal strip continuously transported in a transport direction x with the following steps: Simultaneously determining a first x coordinate xand a first y coordinate yof a point on a surface of the metal strip with respect to an x and a y reference; Determining a second coordinate yof the point with respect to the y reference at precisely the time when the metal strip has been moved in the transport direction x by a predetermined first distance dxwith respect to the first x coordinate x Determining a first y correction value Kby taking the difference between the first y coordinate yand the second y coordinate y; and Using the first y correction value Kto correct the cutting path coordinates describing the predetermined cutting path.
