GRAND RAPIDS — Dematic, supplier of logistics systems for the factory, warehouse and distribution center, has introduced Automatic Speed Control, a new control system that automatically adjusts the speed of the entire sortation system from merge through the sorter take-away conveyors to accommodate actual throughput volume.
Automatically adjusting the sorter speed reduces energy use, wear on equipment, sound levels and maintenance requirements. Automatic Speed Control extends the life of the sorter and conveyors, improves package control, while reducing the cost to operate.
The sorter automatically adjusts to the throughput demand as it changes throughout the day. If there is a surge or decline in flow, the sorter automatically speeds up or slows down to efficiently accommodate the variable rate. With Automatic Speed Control, the sorter does not run continuously at full speed throughout each shift of operation since actual demand vacillates in most warehouse operation. This is how the energy savings is accomplished while allowing less stress on the conveyors and sorter. In a typical system, the speed will vary from 250 feet per minute up to 540 feet per minute depending on the rate of carton flow.
According to Ken Ruehrdanz, Distribution and Warehousing Market Manager, “there are multiple applications for Automatic Speed Control in most operations. In a typical configuration, electronic sensors on the upstream conveyor network detect inbound volume. For a shipping application, electronic sensing monitors downstream availability. If the shipping operation is waiting for more truck trailers or is temporarily under staffed, the sorter can slow down to accommodate”. In this example, the Automatic Speed Control functionality allows the system to refrain from sorting high volumes of throughput to shipping when only a moderate flow can be accepted.
