Abstract: Parcel processing systems and methods. A parcel processing system includes a parcel singulation transport configured to transport a stream of singulated parcels. The parcel processing system includes a parcel sorter configured to sort individual parcels in the stream of singulated parcels into a plurality of buffers. Multiple buffers comprise a set of buffers corresponding to a single load builder, and each buffer accumulates and buffers sorted parcels before transfer to the load builder. The parcel processing system includes a parcel flow merge configured to selectively receive buffered parcels from each of the buffers in the set and feed the received parcels to the load builder. The parcel processing system includes the load builder, configured to receive the parcels from the parcel flow merge and build successive stacks of parcels on a parcel pallet.

Abstract: A sorting system and method. A method includes receiving a plurality of items to be sorted. The method includes assigning a sort criterion to each of a plurality of bins and measuring and storing at least a thickness of each of the items. The method includes assigning each of the items to a bin based on the sort criterion assigned to the respective bins. The method includes transporting each of the items to a respective bin based on the assignments. The method includes determining that the items being transported to a first bin will cause the first bin to reach a capacity threshold based on the stored thicknesses or volume of the items being transported to the first bin. The method includes, in response to determining that the items being transported to the first bin will cause the first bin to reach the capacity threshold, assigning the first criterion to a second bin.

Abstract: A sorting system for postal mail has a plurality of input sections capable of operating in parallel, each including a feeder that takes in mail pieces one at a time and a scanner that scans each mail piece for destination indicia. The system further includes a plurality of stackers each comprising at least one row of pockets in which mail is stacked, and a routing section or switch network effective to route mail in accordance with a sort scheme from any input section to any pocket of a stacker. The routing section uses diverts and merges so that mail can be conveyed to each stacker in accordance with a sort scheme implemented by a control system.
