Carousel Parcel Sorting with Multi-Pass Receptacle Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parcel sorting installations require manual intervention and are not efficiently centralized, leading to inefficiencies in sorting and delivery, especially when handling a large number of destinations.
Innovation Solution
A carousel sorting conveyor system with a monitoring and control unit that performs multi-pass sorting, utilizing high-capacity receptacles for initial bulk sorting and smaller-capacity receptacles for final delivery rounds, along with shuttle robots and OCR for automated address recognition and parcel injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-pass sorting with different receptacle capacities is implemented, then sorting efficiency and automation are improved, but device complexity increases
Solution Approach 1:
The sorting process is divided into multiple passes with different functions: first pass uses high-capacity receptacles for bulk sorting by delivery round, second pass uses smaller receptacles for final destination sorting. This segmentation allows each pass to be optimized for its specific purpose, improving overall sorting efficiency while managing complexity through functional division.
Solution Approach 2:
The system dynamically switches between different receptacle types based on the sorting pass. The monitoring and control unit coordinates the transition between high-capacity receptacles for bulk sorting and smaller receptacles for precision sorting, allowing the system to adapt its configuration to the specific sorting stage requirements.
2Adaptability or versatility
If a large number of sorting outlets are accommodated, then the system can handle more destinations, but the installation footprint increases
Solution Approach 1:
The system nests multiple sorting passes within a compact carousel structure. The carousel conveyor循环 transports bins through multiple sorting outlets in sequence, allowing many destinations to be served within a small physical footprint by reusing the same physical space multiple times in each rotation cycle.
Solution Approach 2:
Instead of arranging all sorting outlets in a single linear array that would require large space, the system uses a circular carousel layout that adds a temporal dimension to the sorting process. Multiple outlets are accessed sequentially as bins rotate through the loop, converting a spatial problem into a temporal solution.
3Ease of operation
If manual sorting intervention is used, then flexibility is maintained, but productivity and automation are reduced
Solution Approach 1:
The monitoring and control unit automatically manages the entire sorting process including bin opening timing, receptacle selection, and multi-pass coordination. The system serves itself by using OCR or barcode scanning to automatically identify parcel destinations and route them through the appropriate passes, eliminating the need for manual intervention while maintaining flexibility through programmable sorting logic.

AI summary
An installation for sorting postal parcels or packets, has a carousel sorting conveyor having transport bins that are moved around a closed loop over a plurality of sorting outlets formed by respective storage receptacles, a feed magazine in which bulk stored parcels are put into series and then injected into the transport bins of the conveyor while it is moving, and a monitoring and control unit that acts on the bins of the sorting conveyor so as to open each of them over a receptacle that corresponds to a delivery address of the article following a sorting plan, includes a first sorting pass to sort parcels into first receptacles that are of high bulk storage capacity, and a subsequent sorting pass where the parcels are sorted into second receptacles that are smaller than the first receptacles.
