Adaptable Rotary Lid Feeding for Overcapper Changeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cup filling machines are difficult to set up and maintain due to their inability to efficiently handle and switch between different shapes of lids, such as round, rectangular, and scround, as they require shape-specific dispensing methods and setups.
Innovation Solution
An adaptable apparatus with adjustable magazine lanes, side guides, and a universal throat plate that can accommodate various lid sizes and shapes, allowing for easy conversion between different lid configurations and facilitating the use of multiple lid styles on the same machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated dispensing system is used for each lid shape (round, rectangular, scround), then the dispensing reliability for each specific shape is improved, but the device complexity and setup difficulty increase significantly
Solution Approach 1:
The patent implements a universal magazine and dispensing system that can handle multiple lid shapes (round, rectangular, scround) through a single apparatus. The magazine is designed with adjustable components including side guides that can be repositioned laterally and rotatably to accommodate different lid geometries, eliminating the need for separate dedicated dispensing systems for each lid type while maintaining reliable dispensing performance
2Manufacturing precision
If shape-specific dispensing methods are used for different lid types, then the manufacturing precision for each lid shape is improved, but the ease of operation and changeover time worsen
Solution Approach 1:
The patent employs dynamic and adjustable components within the magazine system, including side guides that can be laterally repositioned and rotatably adjusted, allowing the apparatus to adapt its configuration for different lid shapes. This dynamic adjustability enables precise dispensing for each lid type while significantly reducing setup complexity and changeover time compared to fixed, shape-specific systems
Solution Approach 2:
The magazine system is segmented into independently adjustable components, particularly the side guides that can be repositioned and rotated separately. This segmentation allows each component to be optimized for specific lid shapes while maintaining overall system precision, and enables easier setup by adjusting individual segments rather than reconfiguring the entire dispensing system
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 apparatus enables efficient and reliable dispensing of multiple lid shapes on the same machine with minimal changeover, improving operational efficiency and reliability of the overcapping function, and allowing for easy switching between lid styles.
Implementation Method 1
a pair of rollers for carrying the lids thereon

AI summary
An apparatus for dispensing lids has at least one magazine lane including an entrance end, an exit end, and a longitudinal length defined therebetween. The at least one magazine lane further includes a plurality of side guides along the longitudinal length for guiding the lids therebetween and a pair of rollers for carrying the lids thereon. The apparatus further has a throat plate at or near the exit end, the throat plate including an opening. At least one of the throat plate, the side guides, or the rollers is adaptable so as to accommodate different sizes and/or shapes of lids.
