Profiled Push Bar for Nested Beverage Container Compaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for compacting cylindrical articles, such as beverage containers, into a nested arrangement are complex, prone to errors, and require intricate structures that are not dirt-resistant, leading to potential malfunctions and increased maintenance needs.
Innovation Solution
A method and device utilizing symmetrically or asymmetrically profiled push bars that move behind the article groups along a tapering transport path, with a profiling that matches the outer contour of the desired compacted arrangement, to shift articles into a nested configuration, reducing gaps and stabilizing the pack through lateral support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If complex conveyor systems with multiple rows and deflection areas are used to achieve nested arrangement, then the articles can be compacted into space-saving configurations, but the device complexity increases and reliability decreases due to collision risks and gap formation
Solution Approach 1:
The patent extracts the essential function of row displacement from complex conveyor deflection systems and implements it through a single profiled push bar that simultaneously engages multiple rows. This removes unnecessary conveyor components and deflection areas while maintaining the nested arrangement capability.
Solution Approach 2:
The profiled push bar serves multiple functions: it displaces multiple rows simultaneously, maintains article spacing, and guides articles into the nested arrangement. This multi-functional element replaces what would otherwise require multiple separate conveyor deflection mechanisms.
2Manufacturing precision
If circulating bars with firmly fixed rollers are used to shift rows of containers, then the desired staggered arrangement can be achieved, but the functionality is restricted and adaptability to different pack variants is reduced
Solution Approach 1:
The push bar is designed with a profile that can be adapted to different pack variants by changing the bar profile itself rather than reconfiguring multiple rollers. The profiled bar dynamically adapts to different container arrangements through profile selection, maintaining precision while improving versatility.
Solution Approach 2:
The invention changes the parameter of the push bar profile to adapt to different pack variants. By selecting different bar profiles (different geometric parameters), the system can handle various container arrangements without mechanical reconfiguration, maintaining manufacturing precision across different variants.
3Adaptability or versatility
If guide plates and disassemblable roller systems are used to enable different pack formats, then adaptability to different pack sizes is improved, but the device complexity increases and dirt-resistance decreases leading to maintenance issues
Solution Approach 1:
The patent removes complex guide plate systems and disassemblable roller mechanisms, replacing them with a single profiled push bar that provides adaptability through profile selection rather than structural complexity. This extraction eliminates dirt-trapping components while maintaining format versatility.
Solution Approach 2:
The push bar profile can be replaced or changed as needed for different pack formats, serving as a simple, easily replaceable component rather than a complex, maintenance-prone system. This approach prioritizes simplicity and ease of replacement over permanent, complex configurations.
