Automated Mail Sweeping Mechanism for Sorting Pockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual removal of mail from sortation output pockets is error-prone and inefficient, leading to misplaced or lost items due to the need for manual handling and the use of cumbersome portable bridges.
Innovation Solution
A set of moveable drawers that align one-to-one with output pockets, allowing for seamless transfer of contents into receiving containers with minimal gap, enabling efficient and accurate movement of mail without manual picking, and automated container handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual handling is used to remove mail from output pockets, then flexibility and simplicity are maintained, but operator errors increase and processing efficiency decreases
Solution Approach 1:
A portable bridge is introduced as an intermediary device between the output pockets and receiving containers. This bridge provides a stable surface that allows operators to efficiently transfer mail while maintaining one-to-one mapping between pockets and containers, thereby reducing errors and improving productivity simultaneously
2Productivity
If portable bridges are used to bridge the distance between output pockets and trays, then transfer efficiency improves, but device complexity and operational cumbersome nature increase
Solution Approach 1:
The portable bridge is designed to be movable and reconfigurable, allowing it to be positioned between different sets of output pockets and receiving containers as needed. This dynamic design enables the bridge to adapt to various sorting configurations while maintaining transfer efficiency, and the bridge can be easily transported between different workstations
3Adaptability or versatility
If multiple handling steps are used to transfer mail, then adaptability to different configurations is maintained, but time consumption and error probability increase
Solution Approach 1:
The receiving containers are pre-positioned in receiving racks with one-to-one correspondence to output pockets. The portable bridge is pre-configured to bridge specific pocket-container pairs. This preliminary arrangement eliminates the need for operators to search for or reposition containers during mail transfer, reducing handling time while maintaining adaptability through the ability to reconfigure bridges for different sorting patterns

AI summary
Presently disclosed embodiments are directed to a process and mechanism for reducing human error and manual labor used to sweep pockets on a mail sorting machine. Specifically, the disclosed embodiments utilize a sliding drawer holding a receiving container that can mate in a flush arrangement with an output pocket of a mail sorting machine. Thus, sweeping of mail product from the output pocket to the receiving container can be accomplished in one motion that empties the entire output pocket into the receiving container. This sweeping may be performed by an operator without any errors caused by sweeping to an incorrect receiving container or issues caused by dropping sorted mail product and picking it back up in a different order.
