Ultimate Mistake Prevention Shutter System

The Shutter Assorting System (SAS) is a small-opening sorting system equipped with the newest light modules with shutters. The system is compatible with both put to light and pick to light, and nearly eliminates sorting mistakes in all cases. The system improves accuracy and efficiency, reduces training costs, and can be used to quantify processes.


  • e-commerce and other workplaces where sorting errors are not tolerated
  • FA sites where important safety parts and the like are managed and sorted, and where errors are not tolerated
  • Workplaces where pharmaceutical products are handled
  • High accuracy requirements by shippers/vendors/users
  • Desire to improve operational efficiency by omitting inspections
  • Searching for a revolutionary system that visually facilitates work for operators

SAS solves these types of problems in the field.

It is very simple to use. The operator scans the barcode of an object, inserts the indicated number of items into the opening behind the open shutter, and presses the “input complete” button to close the shutter. The system can be put to use immediately after installation—there is no need to spend time on training. This is an optimal system for e-commerce and sorting by store.

Prominent Features of the Shutter Assorting System (SAS)

  1. Sorting function

    When the barcode of an object is scanned, the light module of the target opening lights up, and the shutter opens. The computer screen shows a progress bar to enable the operator to view the process of operations in real time.

  2. Opening assignment function

    Sort the operation instruction data by number of items per opening, and assign high-volume items to the openings closest to the operator. The assignment results can be confirmed on the screen that shows the list of recipients. This leads to better workability by streamlining the movement of operators.

  3. Output operation results (CSV export)

    Output operation result data into CSV files. Operation result data is added to the end of the operation instruction CSV file.

  4. Re-display function (find lost items)

    This function re-displays completed openings during sorting operations. Any discrepancies between the status on the system and the actual status can be resolved immediately.

  5. Operation data viewing function

    Operation data can be viewed by recipient, item, and operation status (incomplete/complete).

SAS (Shutter Assortment System) can be provided as a turn key system with a packaged software.
The system can be easily introduced onsite with a short lead time because the necessary functions for sorting operations are built in as standard features.

We also propose optimal system configurations and provide customized systems for various customer environments.
