first_imgA new ship unloader has been installed in a coke bunker plant on the site of Salzgitter Flachstahl in Salzgitter, Germany. The bunker is being loaded either from ship stowages on the canal site or from train wagons on the land side. It is divided into several bunker bins, whose volume can now be determined by 3D laser technology.In order to determine the exact bunker volume contact-less measuring systems by LASE have been applied. They are highly suitable because of their high accuracy, high reproducibility and the robust design. Two 2D laser scanners of the LASE 2000D-11x Series are mounted on the main girder of the ship unloader, such that their scan planes are projected vertically downwards and parallel to the main girder. Both laser scanners deliver 2D profiles where the cross section of the bunker below them is shown.The laser measurement system starts measuring automatically at crane travel and being actuated by a SPS. During crane travel the created 2D profiles are collected and converted into a 3D volume model by the discharging position. Thus the volume of totally eight bunkers is updated permanently and the calculated result is displayed on screen. For the determination of the exact volume even the separating walls or other objects can be excluded from the calculation through suppression areas.The system can be operated intuitively due to user-oriented dialogue control and configuration wizards for simple commissioning. The application has great versatility and can be used for volume and profile measurements in several bunker plant types. This specific software derives from the product line CEWS Bulk Volume Module and distinguishes oneself in the use within rough industrial environments.last_img read more
