Bombay Sorters are typically found in distribution centers that do a lot of direct to consumer operations. The Bombay Sorter handles similar items and operates in the same way that a tilt tray or cross belt sorter would. Bombay Sorters typically have hundreds of sort location making these sorters rather long. However, they do make good use of space with sort location as close to each other as 18” center to center.
These sorters can be engineered to have curves and designed to fit tight warehouse spaces. On all three of these sorters the item being sorted can either have an operator manually place items on the sorter or have an automated induction system that handles getting the items on the sorter.
Once the items are on the sorter they are then scanned and assigned a location to be sorted to. Unlike the Tilt Tray Sorter and the Cross Belt Sorter the Bombay Sorter items fall through a trap door to arrive at its sorted location, hence the name. The items can be sorted into a chute for further processing or dropped directly into a carton or tote ready to ship to its customer.
