Sensor-Guided Conveyor Zoning for Even Parcel Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mail/package sorting systems experience uneven parcel distribution on conveyor belts, leading to backups, loss, and damage due to sporadic batch input, resulting in uneven density and saturation issues.
Innovation Solution
An automated parcel distribution system with a plurality of independently controlled conveyor belts and sensors that adjust speed based on parcel volume measurements to evenly distribute parcels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mail/packages are deposited onto conveyors in sporadic batches, then the input process is simple and flexible, but the parcel distribution becomes uneven causing backups and excessive build-up
Solution Approach 1:
The system dynamically adjusts the speed of individual conveyor belts based on real-time sensor data about parcel distribution. The processor controls each conveyor belt's speed independently to actively respond to varying parcel volumes and maintain even distribution throughout the system.
Solution Approach 2:
Sensors are arranged on lateral sides of conveyor belts to detect parcel presence and volume. The processor receives this feedback data and uses it to adjust conveyor speeds, creating a closed-loop control system that continuously monitors and corrects distribution imbalances.
2Productivity
If a large volume of parcels is output at once from the conveyor, then the throughput increases, but the unloading process becomes overwhelmed causing parcels to fall, get lost, or be damaged
Solution Approach 1:
The system performs preliminary distribution actions by evenly spacing parcels along the conveyor belts before they reach the output point. This prevents overwhelming the unloading process by ensuring parcels are released at a manageable, steady rate rather than in concentrated bursts.
Solution Approach 2:
The conveyor belt speeds are dynamically adjusted based on parcel volume detection. When high volumes are detected, the system slows down conveyors to prevent overload at the output, while maintaining higher speeds when volumes are lower, thus balancing throughput with safe handling capacity.
3Ease of operation
If conventional conveyor belts are used with fixed speeds, then the system is simple to operate, but the parcel distribution remains uneven leading to backups and inefficiencies
Solution Approach 1:
The system uses sensors to automatically detect parcel distribution conditions and adjusts conveyor speeds without human intervention. The processor independently controls each conveyor belt based on sensor feedback, allowing the system to self-regulate and optimize parcel distribution automatically.
Solution Approach 2:
The system changes the operational parameters (speeds) of individual conveyor belts based on detected parcel volumes. By dynamically adjusting these parameters rather than using fixed speeds, the system optimizes distribution efficiency while maintaining ease of operation through automatic control.

AI summary
An automated parcel distribution system includes a plurality of operatively connected individual conveyor belts arranged in zones; a set of sensors arranged on lateral sides of the conveyor belts and at the boundaries between adjacent conveyor belts; and a processor configured to adjust the speed of individual conveyor belts based on sensor data to evenly distribute parcels on the conveyor belts. The processor may receive the data from the set of sensors and determine the volume of parcels in each zone based on width and length measurements of the parcels obtained from the sensors. The processor may slow down, speed up, or maintain a speed of the conveyor belts for a predetermined period in order to evenly distribute the parcels on the conveyor belts. The set of sensors may be arranged on lateral sides and at the boundary between two adjacent conveyor belts.
