Mail processing system and method with increased processing speed
First Claim
1. A mail singulator system comprising:
- a) a loading conveyor configured to advance a mail stack comprising a plurality of mailpieces having a front mailpiece;
b) a controller;
c) an optical panel apparatus comprising;
i) an optical panel;
ii) a mail contact surface;
iii) a planar optical surface that is a fixed color and sheen to allow reliable position determination by an optical sensor; and
iv) a position adjustment feature that adjusts an amount of force required to change a gap distance between the optical panel and said optical sensor;
said force exerted on the optical panel by a front mailpiece;
wherein the optical panel is a flexible sheet of material;
d) said optical sensor that determines a position of the optical panel with respect to the optical sensor;
wherein the optical panel is configured between the front mailpiece and the optical sensor;
wherein the controller changes a loading conveyor speed based on the position of the optical panel.

Abstract
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.
