Automated Mail Tray With Moveable Bottom Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual handling of mail from sortation output pockets is error-prone and inefficient, leading to misplaced or lost items due to human intervention.
Innovation Solution
An automated mail tray system with a moveable bottom plate that elevates to interface with output pockets, allowing for automated transfer of mail into trays without human intervention, using a control system to manage the loading process and prevent errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual handling is used to transfer mail from output pockets to trays, then operational simplicity is maintained, but error rate increases and productivity decreases
Solution Approach 1:
A portable bridge mechanism serves as an intermediary device that connects the output pocket and the tray, enabling automated mail transfer. The bridge includes a bridge ledge that interfaces with the output pocket and a tray interface that interfaces with the tray, eliminating direct manual handling while maintaining system modularity
Solution Approach 2:
The system enables self-service automated transfer where the portable bridge autonomously positions itself between the output pocket and tray, and the mail transfer occurs without human intervention. The bridge can be manually positioned once and then serves multiple transfer cycles automatically
2Productivity
If manual handling is used, then device complexity remains low, but productivity is reduced due to time-consuming operations
Solution Approach 1:
The portable bridge acts as a mediator that enables rapid automated transfer of mail stacks. The bridge ledge receives mail from the output pocket and delivers it to the tray in a single automated motion, significantly increasing transfer speed compared to manual piece-by-piece handling
Solution Approach 2:
The portable bridge is designed to be movable and repositionable, allowing it to dynamically adapt to different output pocket and tray positions. This dynamic capability enables the system to maintain high productivity across multiple transfer locations without requiring a completely fixed automated system
3Manufacturing precision
If manual handling is used, then ease of operation is maintained, but mail order accuracy deteriorates
Solution Approach 1:
The portable bridge serves as a precise intermediary mechanism that maintains the relative positioning between output pocket and tray. This controlled interface ensures that mail stacks are transferred accurately without disruption to their intended order, eliminating the randomness introduced by manual handling
Solution Approach 2:
The system incorporates sensors that detect the presence and position of mail in the output pocket and tray, providing feedback to control the portable bridge's positioning and transfer timing. This feedback mechanism ensures accurate mail order maintenance by preventing premature or misplaced transfers

AI summary
Presently disclosed embodiments are directed to a system and method for loading mail trays in a sorter without human intervention. Specifically, the disclosed embodiments utilize an automated mail tray having a bottom plate that is selectively moveable between an elevated position and a lowered position. The automated mail tray may be positioned on a shelf under a corresponding output pocket of a mail stacker, and the bottom plate may be elevated to receive mail product transferred from the output pocket to the automated mail tray. After receiving the mail product on the elevated bottom plate, the bottom plate of the mail tray may be lowered so that the mail product is transferred from the output pocket to a position fully situated in the automated mail tray. The mail tray filled with mail product may then be removed from the shelf and replaced with an empty automated mail tray.
