Split tray sorter with automatic infeed

With the increasing amount of parcels and rising pressure on delivery times the need for automation has never been higher for CPE, 3PL and e-commerce companies. This is reflected in a growing demand for automatic infeeds. Automatic or semi-automatic infeeds enable a higher throughput and improved accuracy without the need to upscale personnell.

Our solution used at GLS Spain includes a split tray sorter in wide oval layout, combined with roll container tipper, conveyor belt, pocket belt, scanners and auto infeed. Inbound items are transported in roll containers and leave the premises in large postal bags. Due to the station layout with large bags and the limited available space, the infeed had to be placed on a raised platform. To supply the operators with a continous flow of items and maintain their productivity, the conveyor belt is used as a induction buffer.


  1. Roll containers
    Items arrive in roll containers. These containers are transported towards the sorter for further handling.
  2. Conveyor belt
    The roll containers are emptied and items are put on the conveyor belt. This conveyor moves the items to the raised platform, supplying the operators with a continuous flow of items. The process of emptying the roll container can be further automated by using roll container tippers. This reduces the physical load of operators and offers a more ergonomic and efficient solution.
  3. Pocket belt
    Operators on top of the platform only need to correctly position the items on the pocket belt. This greatly increases their productivity and with it the throughput of the sorter.
  4. Identification and scanning
    The  integrated  scanning  system  reduces  human  error  by employing accurate and fail-safe scanning. After the pocket belts the barcodes will be scanned on 2 sides: top and bottom. The identification can be expanded with other integrations such as dimensioning, weighing and scanning (DWS) or Optical Character Recognition (OCR).
  5. Infeed
    The automatic infeed system ensures the parcels are correctly  induced  in  the  sorter  system.  By  automating  this  task,  the  amount  of  errors  can  be  drastically reduced. This specific split tray installation with wide oval layout can handle over 12.000 parcels per hour.
  6. Split tray sorter
    In this example we have included a split tray (bomb bay) sorter. However, the automatic infeed is not limited to this installation and can be integrated for all our sorters.
