Automated control of on-edge envelope stacking

A system for providing autonomous on-edge stacking of mailpieces, the system comprising:

• an on-edge stacker module configured to sequentially receive a plurality of incoming mailpieces in a flat position and reorient each mailpiece to an on-edge position and stack the plurality of on-edge mailpieces face-to-face in a given stack on a stack accumulating belt, wherein the on-edge stacker module comprises:
• at least a first sensor configured to measure a thickness of an incoming mailpiece;
• and
• a second sensor configured to measure a pressure of a given stack of on-edge mailpieces into which the incoming mailpiece is to be inserted upon being reoriented into an on-edge position;
• wherein the first sensor is configured to measure the thickness of the incoming mailpiece as it passes into the stacker module toward a belt turn-up assembly for reorienting incoming mailpiece from the flat position to the on-edge position;
• and
• a controller configured to communicate and exchange data with the on-edge stacker module, the controller comprising a hardware processor coupled to non-transitory, computer-readable memory containing instructions executable by the processor to cause the controller to:
• receive and process data from one or more sensors of the on-edge stacking module;
• and
• autonomously control movement of at least the stack accumulating belt based, at least in part, on the processing of data to thereby maintain a constant ideal stack pressure of a given stack of on-edge mailpieces as each incoming mailpiece is received, reoriented, and subsequently inserted into the given stack.
