Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sorting systems for parcels in logistics require expensive handling devices and robots to handle bulk flows of parcels with varying sizes and shapes, necessitating multiple devices to manage high volumes efficiently.
Innovation Solution
A method involving the use of multiple transport means with varying speeds and angles to transform three-dimensional parcel flows into one-dimensional flows, utilizing conveyors with side guides and defectors to separate and align parcels, reducing the need for multiple handling devices by expanding surface area and creating gaps between parcels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handling devices and robots are used to grip and place individual parcels, then singulation of bulk flows can be achieved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The system allows parcels to self-singulate by utilizing their own weight and the conveyor's motion. Parcels are deposited onto a moving conveyor at an angle, causing them to naturally slide and separate based on their orientation and weight, eliminating the need for active gripping and placement mechanisms
Solution Approach 2:
The patent replaces complex mechanical gripping systems with a simplified conveyor-based system that uses controlled deposition angles and conveyor motion to achieve singulation through physical principles rather than mechanical manipulation
2Productivity
If multiple handling devices are used to manage high parcel volumes, then processing capacity increases, but device complexity and cost increase
Solution Approach 1:
The system transforms the three-dimensional bulk flow of parcels into a two-dimensional spread on the conveyor surface, then into a one-dimensional single-file flow. This dimensional reduction allows high-volume processing with a single conveyor system rather than multiple handling devices
Solution Approach 2:
The conveyor operates dynamically with adjustable speeds and the deposition mechanism varies the release angle based on parcel characteristics, allowing a single system to adaptively handle varying volumes and types of parcels without requiring multiple fixed-capacity devices
3Measurement precision
If sensor systems and grippers are used to detect and handle parcels, then accurate singulation is achieved, but manufacturing cost increases
Solution Approach 1:
The system uses the parcels' own physical properties (weight, shape, orientation) and the conveyor's motion to achieve detection and positioning without external sensors. The deposition angle and conveyor speed work together to naturally orient parcels correctly
Solution Approach 2:
The system achieves precise control by varying physical parameters such as conveyor speed and deposition angle rather than using sensor feedback, reducing manufacturing cost while maintaining effectiveness
4Ease of operation
If conventional sorting systems are used for bulk flows, then individual parcel handling is achieved, but system complexity and cost increase
Solution Approach 1:
The system segments the bulk flow processing into distinct phases: deposition at an angle, spreading on the conveyor surface, and merging into single-file flow. This segmentation allows complex bulk flow handling to be achieved through simple, sequential operations
Solution Approach 2:
A single conveyor system performs multiple functions: it transports parcels, spreads the bulk flow, facilitates singulation, and outputs individual parcels. This multi-functionality eliminates the need for separate handling devices for each operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method effectively singulates parcels from bulk flows into a one-dimensional flow, reducing the complexity and cost of handling by using existing conveyor systems to manage high volumes with increased efficiency and reduced device requirements.
Implementation Method 1
the friction between the packages and the conveyor belt is increased, in particular by means of a rough conveyor belt surface
Implementation Method 2
the rotating body is caused to rotate at high speed, in particular at least 1000 rpm, by friction against a surface which is stationary relative to the movement of the conveyor belt... centrifugal force to separate rotationally symmetric packages

AI summary
The invention relates to a method for the singulation of packages, especially for the singulation of parcels. The invention is based on the assumption that the parcels are initially present as a bulk flow. The packages are transported in the form of a package flow on fifteen different transport means at different transport speeds, whereby the transport direction is deflected at least once by approximately 90°.
