Anti-abrasion assembly for mailpiece stacking assembly

摘要

A stacking assembly is operative to protect stacked mailpieces (14) from damage due to abrasion. The stacking assembly includes a support blade moveably mounted to a bin for accepting a stack (14S) of mailpieces (14) and an ingestion assembly (90) including a Leading Edge (LE) urge roller (84) and Trailing Edge (TE) alignment device. The LE urge roller (84) is operative to accept mailpieces (14) from a supply of mailpieces, and urge a leading edge portion thereof toward a sidewall of the stacking bin. The TE alignment device includes a first cam (100) driven about an axis of rotation by a digital rotary positioning device which cam (100) defines a surface operative to urge the trailing edge portion of each mailpiece (14) into parallel alignment with the support blade. The stacking assembly also includes an anti-abrasion assembly (200) responsive to rotation of the digital rotary positioning device to forcibly displace a surface of the stacked mailpieces (14) away from a moving surface of the ingestion assembly (90).
