On paper, then, the performance of the latest sorters is impressive.
Realising the expected levels of throughput demands a full analysis of the complete material flow, taking into account factors such as the types of products to be handled, fluctuations in throughput levels, how the products will be inducted, whether the handling systems at the input/exit points can match the speed of the sorter and whether product grouping can avoid unnecessary delays in delivery procedures and simplify point-of-sale stocking operations.

With all the relevant data collected and evaluated, simulation can be used to test various alternatives and identify potential bottlenecks. Eventually a schematic layout can be produced, showing information such as flow rates. Only then, should equipment be selected to provide the most effective solution.

While this article has tended to focus on the top-end of the performance scale, it is equally important to stress that it is possible to justify the introduction of a new sorter system for throughputs of just a few hundred items per hour, using simple pneumatic pushers/pullers.

Whatever the scale of the application, the best approach is always to identify the requirements of the system, then select the right sorter for the job.
