LaseAFM - Automatic Freight Measurement

Published in Freight Logistics

The system LaseAFM-4 (Automatic Freight Measurement) for the automatic and multi-dimensional freight measurement delivers highly accurate measurement data for freight forwarders and ensures higher transperency as well assaving of time in transshipment stations. By the automatic detection of the volume, dimension, weight, freight-ID and image data, manual measurements and transcription errors are excluded within the freight documentation process.

The measurement sequence - easy and accurate:

  1. Freight is placed in measuring station
  2. Freight-ID is scanned by hand-held scanner
  3. Automatic initiation of the measurement process
  4. Freight volume measurement by 3D laser scanners
  5. Freight weight measurement by weighing system
  6. Imaga data acquisition by HD camera
  7. Data transfer to WMS-/ERP-System

With the use of state-of-the-art 3D-Laser scanners (mounted at the four portal corners) LaseAFM-4 measures all dimensions with highest accuracy. The measurement process starts at the push of a button at the operator terminal or by scanning the freight-ID (if Module I - Ident is applied). Even during the 3D-Laser measurement also HD pictures of the freight object are taken for comprehensive consignment information. The complete freight measurement procedure only takes a few seconds and all detected freight information is forwarded to the warehouse management system (WMS). A further module for the generation of weight measurement data (Module W - Weight) can be added optionally.

The accurate and automatic 3D-Laser volume measurement combined with the freight weight generate reliable freight data and avoid wrong freight rating. Nowadays false data or faulty transcriptions of manually recorded freight data cause significant financial losses. By using our accurate and automatic measurement system LaseAFM-4 the consignor and carrier stay toghether as business partners without burdening their good relation through faulty freight data.

Exact 3D scrap volume measurement and material selection at Lech-Stahlwerke GmbH

Published in News

 

07.12.2016 // Scrap on demand – exact 3D volume measurement and material selection at Lech-Stahlwerke GmbH

LASE provides an exact steel scrap measurement system in two different operation areas for Lech Stahlwerke GmbH (LSW) in Meitingen, Germany. The laser measurement systems by LASE determine the volumes of different steel scrap materials both in the storage area and in the scrap ferries permanently. For this reason the dosing of recycled steel scrap can be improved and even the quantity of each material sort in the storage area can be determined, too. LSW produces high quality steel products from recycled raw materials and belongs to the division “Steel & Production” within Max Aicher Group.

Scrap storage measurement

In the storage area scrap materials are stocked according to their sort in totally 32 parcels, which are actuated by two crane systems. For the measurement of the scrap area two 2D laser scanners from the LASE 2000D-11x-Series are mounted on the main crane girder. Their scan planes are vertically downwards as well as parallel to the crane and deliver so called 2D profile data. Each single profile shows a cross section of the scrap pile, which are located under the laser scanner. For the measurement of the scrap volume a measuring drive is executed, which is initiated by telegram from the PLC control. A further evaluation unit from LASE (LCU – LASE Control Unit) collects the incoming 2D profiles and converts the values together with the crane position data into a 3D volume model. Separating walls for the segmentation of the storage area are filtered out by the measuring software and are excluded from the volume determination.
By the additional crane position measurement the storage management system always knows from which of the 32 parcels any material has been removed. Due to the knowledge of the exact volume for each single scrap material type LSW is able to manage the storage area and also to plan the disposition appropriately.

Scrap ferry measurement

After the steel scrap has been loaded from the storage area into a scrap bucket by crane, it is transported by a ferry to the electric air furnace. The measurement starts when an empty scrap ferry drives through the scan plane of the 2D laser scanner (LASE 2000D-11x-Series), which is mounted on the ceiling. The measuring procedure is triggered automatically just as the software detects the ferry in a predefined height. The collected profile data of the ferry are filtered by specific algorithms of the LASE-Software, with the result that associated parts of the ferry are not calculated mistakenly. By the help of a specially developed bucket edge detection function the bucket can be extracted precisely. The process is divided into an empty profile (reference measurement with zero volume) and a full profile measurement, where the fully loaded bucket is moving through the measurement system. The volume of the scrap material is determined by the difference of the empty and full profile.

 All in all both installed laser measurement systems help LSW optimizing storage and production processes by the exact determination of the steel scrap quantities. In order to measure volumes laser measurement systems by LASE are highly suitable due to their high accuracy, high reproducibility and high robustness. The 2D laser scanners from the LASE 2000D-Series are versatile and also be applied for positioning and anticollision tasks.

31.10.2016 // German steel producer Salzgitter Flachstahl AG operates with bunker volume measurement system LaseBVB

A new ship unloader has been installed in a coke bunker plant on the site of Salzgitter Flachstahl GmbH in Salzgitter, Germany. The bunker is being loaded either from ship stowages on the canal site and from train wagons on the land side. It is divided into several bunker bins, whose volume can be determined by 3D laser technology now.

In order to determine the exact bunker volume contact-less measuring systems by LASE have been applied, which are highly suitable because of their high accuracy, high reproducibility and the robust design. Two 2D laser scanners out of the LASE 2000D-11x Series are mounted on the main girder of the ship unloader, such that their scan planes is 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 a high 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.

27.07.2016 // Implementation of Truck Volume Measurement system (LaseTVM) together with Russian partner 000 Fest in the plant of Keramzit in Nizhnekamsk, Russia. Within this project not only a plain volume acquisition has been applied, but also data handling of license plates or photographs of empty trucks. For this reason the whole process is unified into one solution and helps to improve the process chain in bulk material handling.

The application LaseTVM - Truck Volume Measurement is a highly precise three-dimensional measurement system especially developed for measurements of truck loading volumes. Two 3D laser scanners from the LASE 3000D-C2-11x series are installed over the entry of the loading area and measure the volume of trucks, which drive into and out of the plant. After arriving, the trucks have to stop under this 3D measurement system in order to determine the volume of the empty trailer. After being loaded with bulk material, the trucks have to stop again under the 3D laser scanners in order to determine the fully loaded trailer as well.

It also doesn't matter if the trucks have a single or double trailer. Both volume measurements (empty and full) are forwarded to the application software LaseTVM, which operates with specific software algorithms. The differential value out of the current loading quantity and the empty profile amounts to the loading volume.  The 3D laser scanners are installed in a height of 5,50 m and in a distance of 8,00 m to each other - wide enough to cover the whole truck-trailer length with their scan planes.

Further system functionalities in this implementation are the recognition of the correct truck position within the 3D laser measurement area with light signals, data reception from license plate recognition and empty truck photographs, too. Due to system implementation in winter time, it was able to proof its robustness under rugged outdoor conditions immediately!

The application has a high versatility and can be used for volume and profile measurements of all different materials - such as ore, stones, sand or even wood chips - which are transported as bulk material on trucks. It elimates faulty weight measurements by e.g. humidity within conversion (up to 20% of the volume) and can exclude weight manipulations. This highly exact laser measurement system has an accuracy of approx. 2% and ensures a comfortable resource planning for the customer.

21.07.2016 // Further two reclaimers have been equipped with 3D laser measurement system at ADANI ports in Mundra, India. The system also includes a specific manager application, where a segmentation of multiple piles is shown as well as volume and weight information. A high reusability for further projects was concluded.

The system for heap volume measurement determines information like e.g. volume, 3D profile, peaks by using 3D laser scanners from the LASE 3000D-S-13x Series, which are installed on top of a stacker/reclaimer machine. In total two machines have been equipped with laser scanners at Adani, whereof three piles can be measured simultaneously. The laser data information from both machines are shown within a manager application. Here all different heaps/piles are displayed clearly and a segmentation of the material is possible, too. Due to fulfil specific customer needs, weight measurement data will be also recognized within the manager application.

Depending on the heap-size, one (or more) 3D-laser scanner is installed on a machine for the realisation. This scanner is „looking“ above from the machine on the heap and scans the heap profile. In connection with the current stacker position a 3-dimensional image of the whole heap profile can be developed and compared to a „0-profile“within the application software, which has been taken during the calibration. Out of the obtained data the LASE CEWS application software calculates the profile and the volume of the heap precisely. The current filling level of each single field is transferred to the process control system, which recognises the removal/supply of material automatically.

Increasing numbers of customers need to automate their stackers and reclaimers within the raw material stockyards. In order to drive the machines automatically, it is necessary to know the profile of the piles on both sides of each machine. For this purpose 3D laser measurement technology is the most suitable technology.

The system can be operated intuitively due to user-oriented dialogue control and configuration wizards for simple commissioning. The software analyses the raw data and divides the measured volume into a grid pattern. Then the current filling level of each single field is transferred to the process control system. By this information the process control system recognises the removal/supply of material automatically. Important state messages are logged and clearly displayed for additional documentation purposes. For integration in production plants all common interfaces are available, too.

The application has a high versatility and can be used for volume and profile measurements in several types of bulk material storages. This specific software derives from the product line CEWS Bulk Volume Module.

Fall pipe and bulk measurements on Jan De Nuls "Subsea Rock Installation Vessel"

Published in News

While the Bavarians are happy about winning the Triple, LASE installs even FOUR applications on one vessel! Dredging specialist and operator Jan De Nul utilizes laser scan and bulk measurement solutions by LASE for the Joseph Plateau - a "Subsea Rock Installation Vessel".

The world leader in dredging works, land reclamation and cable- or pipelaying on the global oceans orders four different measurement systems for its latest ship Joseph Plateau. Our proven laser technology is used on a 191 m long vessel for precise rock dumping in a depth of up to 2.000 m for the protection and stabilization of subsea pipelines. The system for the assembly of the fall pipe is extremely advanced and operates fully automatically. Due to the repeated successful collaboration with the company Jan De Nul, LASE was able to distinguish oneself in the area of intelligent laser measuring technology through its expertise in this huge project.


The complete turnkey solutions are divided into the following four applications:

1. LaseFPM - Fall Pipe Position Measurement  

2. LaseFDM - Fall Pipe Distance Measurement

3. LaseBVB - Bulk Volume Bunker

4. LaseBPC - Bulk Profile Conveyor


 

1. LaseFPM - Fall Pipe Position Measurement

On this special vessel fall pipes are used for covering undersea cables with filling material which are stuffed on board. These fall pipe consists of several single pieces which are put into each other by a robot.  Due to the state of the sea the fall pipe moves in a scope of about 2 m. For the assembly of the fall pipe it is important to determine relative position between the pipe in the water and the next pipe which has to be attached. The position will be profiled and detected in an average time of 12 msec with an accuracy of +/- 10 mm at a distance of about 5 m.

2. LaseFDM - Fall Pipe Distance Measurement

The second fall pipe measurement system was created to determinate the distance of a top-flange and the bottom-flange of a new pipe from a pipe string to reduce the impact at contact. For the mounting operation four laser scanners have to be installed which are also able to detect the vertical scan area at rough sea and the resulting vibrations of the pipe. In the case of dismounting only one laser scanner needs to be used due to a higher position of the pipe removal. With a pipe diameter of 1.000 mm the scan planes are in a distance of 800 mm to each other. In total the hardware equipment in this application consists of five 2D-scanners and one specific LASE processing unit for evaluation operations.

  • Exact flange distance detection out of 2D profile data
  • Applicable for mounting & dismounting operations of the fall pipe
  • Suppression of ropes & pipes inside the scan range
  • Accuracy of 50 mm for pipe distance measurements

3. LaseBVB - Bulk Volume Bunker

At this system solution out of the bulk measurement range, four 3D laser scanners are installed above both bunkers. At each bunker two scanners are „looking“ down on the bunker and scan its volume and profile. Out of the raw data a 3-dimensional image of both bunker profiles will be developed and compared to a so called „0-profile“ which was taken during the commissioning at the beginning. Out of the obtained data from the LASE CEWS application the software calculates the profiles and the volumes of both bunkers parallel and precise. Additionally it is also possible to extract mechanical parts (e.g. excavators in the middle of the bunker) from the scan/profile data due to special filter technology. Because of the accurate volume measurement a continuous inventory can be processed and provides a basis for material disposal.

http://www.lase.de/en/applications/volume.html



4. LaseBPC - Bulk Profile Conveyor

In this application out of our Bulk Logistics range up to four 2D-laser scanners are installed above the two conveyor belts of the vessel. At each conveyor belt a scan level across the conveying direction of the belt is projected. A two-dimensional image of the bulk material will be developed and compared to a so called „zero-profile“ which was taken during the commissioning at the beginning. Out of the obtained data the software calculates the volume and mass flow rate of both conveyor belts parallel. By the use of high performance laser scanners with a scan ratio of up to 300 scans per second, the material is recorded reliably even at a high transportation speed (see fig. 8). Special algorithms for the adjustment and calibration ensure a high accuracy. The LASE measuring system allows a safe operation even under raw environmental conditions.

LaseWVI - Waste Volume Incinerator

Published in Waste Logistics

Bunker filling level and profile measurement in waste incineration plants: The system by LASE gives high dynamic feedback of the filling level to the control system.

System features:

  • Optimal charging and debris mining in the storage area
  • Exact illustration of the mound profile
  • Large range (80 m)
  • Several crane installations can be equipped in parallel
  • Multi-shelf-life
  • Rugged construction type

Short description:

A 2D-laser scanner is attached to the portal of the crane and the data from the laser scanner is supplied to a LASE Control Unit (LCU). A 2-dimensional profile of the bunker is built up by the laser scanner and in connection with the position of the crane a three-dimensional profile of the bunker will be generated. The bunker is divided into fields similar to a chessboard and the measuring system then provides the min., max. or average value of the height in each chessboard field. It is also possible that several crane installations in the same bunker can also work together whereby each crane is equipped with a laser scanner.

In total the software can accommodate up to 4 bunkers and it is also possible to implicate a Bunker-Management software for the organisation of waste bunkers. Furthermore an additional collision avoidance system is also available in order to contribute to decreased risks of crane failure while (automated) operation and improved safety for personnel and equipment.

Published in Mining Volume

Measurements of profiles and volumes of bulk material are a typical job for our laser technology: LASE also establishes systems for heavy industry environments. 

System features:

  • Exact volume measurement
  • Continuous inventory
  • Planning base
  • Simple installation
  • Low investment costs
  • Quality covering and –improvement
  • Process optimization
  • Documentation
  • Basis for process automation

Short description:
