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.

A mail singulator system determines a position of an optical panel to automatically adjust a loading conveyor speed to prevent stacked and overlapped mailpieces in the singulator and large gaps between mailpieces. The optical panel is configured between the front mailpiece of a mail stack on the loading conveyor and the optical sensor. The optical panel changes position with the pressure exerted by the mail stack and provides signals to the controller to adjust the conveyor speed. An optical sensor may detect a far threshold position or limit distance to increase the speed of the conveyor and may detect a near threshold position of limit distance to reduce the speed of the conveyor. The optical panel may have a low friction surface to allow the mail to slide into the conveyor and an optical surface to allow reliable optical sensor detection of the optical panel position.

A mail hazard screening machine is configured to compress mail pieces or envelops through compression rollers and draw out this air and any hazard that may have been contained in the envelope. The system may be able to detect a wide range of hazards such as chemical, biological, radioactive, nuclear, explosive and drugs, abbreviated CBRNE+D. The sample air, the air drawn out from the hazard screening system, may be directed to one or more analysis devices and the mail processing machine may be stopped if any hazard is detected. The mail piece containing the hazard can then be found and further inspected safely.

A mail feeder system may be configured to deliver mail pieces to the hazard screening system without compression of the mail pieces or envelopes

A mail processing system utilizes a conveyor to shingle or de-shingle mailpieces as they move through the processing system and utilizes belts to move the mailpieces. A first shingling conveyor moves a first mailpiece to overlap with a second mailpiece to create shingled mailpieces. A second shingling conveyor moves a first mailpiece away from a second mailpiece to de-shingle them to create singulated mailpieces. A camera takes images of the mailpieces in the conveyor and image analysis software is used to determine dimensional aspects of the mailpieces that are used to control the belt speeds to move mailpieces with respect to each other. A mail processing system may include a mail processing station that scans addresses, applies postage and/or weighs the mailpieces. Mail may be de-shingled prior to being weighed and then re-shingled for subsequent processing, or mail may shingled prior to passing through a scale if weighing is not necessary.
