Automated Package Processing System [APPS] Update February 23, 2006
Agenda n System Description n Deployment Status n Bundle Processing – Address Visibility – Bundle Integrity n APPS Singulator Design
APPS System Description Dual Induction, 100 Output
APPS System Description Mail Characteristics Maximum weight = 25 lbs
APPS Deployment Status n Phase n First I - 74 Machines, 62 sites Article Test completed May 2004 n Deployment from Aug 2004 to Aug 2006 – Currently have 55 machines in operation
Bundle Processing Address Visibility Optical Character Recognition (OCR) – Reads both Optional Endorsement Line (OEL) and address block information to sort the mail – Current read rates for OEL bundles is around 80% – Read failures occur due to: – Address block obscured by opaque strapping material – Address block is obscured by opaque shrink wrap
Image Capture Gray Scale Image – 5, 807 Kb OCR decodes Binary Image – 201 Kb
APPS Images n Opaque Material n Address Block Location
Clear Strapping
APPS Image - Polywrap n Poly weld seam through address block n Image captured at semi-auto induct station n Piece was rejected by video coding operator
Address Visibility Rule n DMM Change - Address visible and readable to the naked eye n Where the label WILL be covered – If practical - move the address to one of the four quadrants – Clear smooth strapping (recommend less than 70% haze – ASTM D 1003) – Clear shrinkwrap (recommend less than 70% haze – ASTM D 1003) Effective – April 30 th, 2006
Bundle Processing on APPS Bundle Integrity n Automatic Singulation – Bulk input to single bundle output – Designed for wide variation in frictional characteristics – Destacking produces tumbling
Bundle Processing on APPS Bundle Integrity n Shrinkwrap no longer required on bundles on BMC pallets (Implemented in 2005) n Two straps on all non-shrinkwrapped bundles (Tentative effective date April 30) n Information sharing – Bundle Blitzes – The Perfect Bundle – Recommended quality test for bundles – Electronic Mail Improvement Report (E-MIR)
Bundle Processing on APPS Bundle Integrity – USPS/Mailer Study n Define characteristics of bundles n Design an experiment to measure bundle performance on APPS – Greensboro P&DC test site – Preliminary meeting in early February – March 2006 data collection
Bundle Processing on APPS Bundle Integrity n Singulator Design Study – Engineering task to evaluate destack module – Assess feasibility of reconfiguration to reduce tumbling – Findings in 6 months
Questions? The Perfect Bundle A secure bundle with a fully visible address is a thing of beauty
