Automated Picking with A-frame

Interpharm, a pharmaceutical wholesale company in the Netherlands, developed a smart concept for two of their warehouses. They are able to reach a exceptionally high level of warehouse productivity.

The company has done well in the past years and the operation has outgrown itself. This triggered a full analysis of the logistics. After comparing the options of having one central distribution center versus several DC's, it was decided to maintain the current (decentralized) operation.


As for most companies, flexibility and speed are crucial components in Interpharm's logistics. They supply their clients (pharmacies) two times each day, usually 2-4 hours after the order has been placed. The logistical challenge is great!

KNAPP supplied the automated picking systems, which enable the warehouses to pick about 15,000 lines per day with a failure rate lower than 0.2%. Each warehouse has a so called A-frame (see picture) and fully automated and integrated conveyor systems.

The A-frame is designed for the automatic picking of items with a high or very high turnover rate. It automatically picks fast moving products onto a central belt, which transports the products to a container on a different conveyor belt. Other products are picked in the same container, which is then delivered to the customer. The timing of the picking by the machine and the moment the container is filled with the picked products is coordinated to increase picking productivity.

The main advantages of the A-frame: manpower can be reduced significantly, extremely high productivity, high reliability and accuracy and gentle handling of products.
