Logistics management system

For the storage of up to 14.000 components we assisted a customer from the field of machine engineering to realize an optically controlled high rack system. Size, type and article description of the objects need to be recorded as well as their weight, so the boards can be optimally loaded and the linked ERP system updated respectively.

    To take a picture of the board several cameras incl. optics are installed on the ceiling of each compartment. Like this, we are able to get a complete image of the respective storage area in the end.
  • User interface

    The clear user interface enables the operater to select the required storage area easily and quickly. The application can e.g. be used with a tablet.

    Due to lack of space every camera only takes one part of the picture. In the following the single images are put back together using stitching algorithms.

Using a separate camera-based scanning system with 3D volume measurement, barcode and character recognition as well as the option of classification, every new component is first added to the inventory management system or the database with its specific values. A system based on four cameras generates point clouds from different perspectives to determine the external dimensions in 3D and thus calculate the volume. The trained objects can be recognized or distinguished by similarities without using OCR or barcodes/2D codes. To register the object to be newly stored the operater provides it to the scanner integrated to the rack, before the part is then stocked.

To not exceed the specified maximum mass for the boards the rack manufacturer performs weight measurements to keep the total load updated at all times. For the additional capture of objects as well as of free storage space on the boards, a second image processing system is installed. The components used for the optical inspection are integrated into the high racks. During the stocking process the multiple camera system saves images of the current state of load. Free storage space is measured in volume on each board. Both loading status and volume of free space are added to the database together with the still loadable weight.

The operator can then call up this information, review it and choose a board suitable for storing the next component easily with a click. After stocking the respective parts, a new image is taken and saved again to always remain up to date. At the same time the stored objects are identified once again at the image acquisition using matching algorithms. Thus, the storage of the products is always conducted in coordination with the ERP system.

The system is designed completely modular. Every single function is executable on its own and can be extended by the other features. A scanner for capturing goods in the ERP system can be used as an individual system as well as the storage system itself. In the present case a complete integration into the internal system was implemented to merge all components and information the best way possible.
