Double-Inclined Packaging Separation Machine for Cylindrical Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging separation machines struggle to effectively separate closely packed pharmaceutical packagings, particularly cylindrical ones, and require complex and costly additional systems to correct errors, while existing solutions are not mechanically simple or cost-effective.
Innovation Solution
A transport belt system with longitudinal and lateral inclinations, featuring flights with specific dimensions and a movable base wall, ensures precise separation of packagings by aligning and sliding them into a row, suitable for both cylindrical and non-cylindrical shapes, using a cascading belt configuration with asynchronous control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a planar transport belt is used to separate packagings, then the structure is simple, but the separation effectiveness is poor especially for closely packed or cylindrical packagings
Solution Approach 1:
The transport belt is given a double inclination: a first inclination angle (α) between 30°-45° in the longitudinal direction to prevent friction-based pushing, and a second inclination angle (β) between 5°-15° in the transverse direction to promote lateral alignment. This two-dimensional inclination approach enables effective separation of closely packed and cylindrical packagings without complex mechanisms.
2Manufacturing precision
If the longitudinal inclination angle is increased to prevent packaging sliding, then separation effectiveness improves, but cylindrical packagings may roll on the belt
Solution Approach 1:
The flights are designed with specific local characteristics: their transverse dimension is at least equal to the radius of the greatest cylindrical container to be transported, and their height is slightly less than the minimum dimension of the box to be moved. This localized adaptation allows cylindrical packagings to be effectively separated without rolling, while maintaining the longitudinal inclination angle (α) between 30°-45° for preventing friction-based pushing.
3Reliability
If additional systems like vision systems are added to correct separation errors, then separation reliability improves, but device complexity and cost increase
Solution Approach 1:
The transport belt with double inclination and specifically dimensioned flights creates a self-aligning system where packagings automatically line up in a row in the region of the second longitudinal side during transport. The lateral inclination (β) causes packagings to slide laterally and slowly, enabling self-correction of positioning without requiring external vision systems or complex control mechanisms.
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
The system achieves effective separation of packagings, including cylindrical ones, with reduced installation and maintenance costs, by aligning and sliding them into a row, ensuring minimal overlap and efficient transfer to subsequent processing stations.
Implementation Method 1
The lateral inclination promotes an alignment of the packagings in a row, in the region of the second longitudinal side
Implementation Method 2
the inclination is sufficient to prevent packagings from being able to be pushed on the transport belt simply by friction on a support plane of the transport belt

AI summary
A machine for separating packagings includes a transport belt which is inclined longitudinally at a first angle and laterally at a second angle so that a first longitudinal side is positioned higher than a second longitudinal side. The transport belt is further provided with a plurality of flights which are arranged near the second longitudinal side.
