Dynamic Divider Sorting System for Parallel Stack Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current industrial sorting systems face inefficiencies in processing large volumes of items, leading to significant time losses as sorted collections occupy collection areas, hindering further sorting processes.
Innovation Solution
A system comprising a pocket, a sorter, a divider, and a controller, where items are injected into a pocket to form stacks, and a divider is dynamically extended to separate stacks, allowing for the removal of one stack while continuing to sort and receive new items, enabling simultaneous processing and allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sorted collections of items are removed from collection areas after sorting, then the same collection areas can be reused for further sorting processes, but this sequential removal and processing approach leads to significant time losses and processing inefficiencies
Solution Approach 1:
The system maintains continuous sorting operations by enabling multiple pockets to be filled simultaneously. While one pocket is being processed for removal, other pockets continue to receive and sort items, eliminating idle time and ensuring the sorting system operates continuously without interruption.
Solution Approach 2:
The collection area is divided into multiple independent pockets that can operate in parallel. Each pocket can be filled, processed, and removed independently, allowing the system to segment the sorting process into concurrent operations rather than sequential steps, thereby reducing total processing time.
2Productivity
If a single collection area is used for sorting items, then the system structure is simple, but the collection area must be emptied and reused sequentially, reducing processing throughput
Solution Approach 1:
The collection area is segmented into multiple pockets arranged in parallel. Each pocket functions as an independent collection zone that can be filled and processed separately. This segmentation enables multiple sorting operations to occur simultaneously, increasing throughput while maintaining a relatively simple overall system structure.
Solution Approach 2:
Each pocket is designed to be multi-functional: it can receive items, hold sorted collections, and be independently processed for removal. The pockets can be reused cyclically, with each pocket serving multiple sorting cycles, thereby increasing productivity without requiring a proportional increase in total system complexity.

AI summary
Sorting systems and methods for large quantities of items in industrial processes are described. The systems, devices and methods are for receiving, sorting and removing items dynamically. A first group of items, such as letters or other mail pieces, are injected by a belt into a pocket to a form a first stack, and a divider is extended near the first stack. The divider allows for a second group of items to either be injected to form a second stack behind the divider, or to be diverted and injected into another pocket. The first stack can be removed while the second group is being injected.
