Turret Cutout Groove for Clean Container Member Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container member supply devices, such as lid supply devices in seaming devices, have complex structures that are costly and difficult to disassemble and wash, and they can cause damage or abrasion powder issues during the lid separation process.
Innovation Solution
A container member supply device with a container member separation unit that includes a cutout groove integrally provided on the upper outer periphery of the container member conveyance turret, which engages with the flange of a container member, allowing for simplified structure and reduced risk of damage or abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a three-screw type lid supply device is used, then the lid separation function is achieved, but the device structure becomes complicated and costly
Solution Approach 1:
The patent combines the lid separation function and the conveyance function into a single integrated structure. The conveyance turret itself has a cutout groove formed on its outer periphery, eliminating the need for separate cutout rolls. This merging of functions reduces the number of components from three cutout rolls to one integrated turret structure, simplifying the overall device while maintaining reliable lid separation.
Solution Approach 2:
The conveyance turret is designed to serve multiple functions: it conveys lids to the seaming position and simultaneously performs the lid separation function through its cutout groove. This multi-functional design replaces the dedicated three-cutout-roll separation mechanism, reducing structural complexity while achieving the same separation reliability.
2Reliability
If a three-screw type lid supply device is used, then the lid separation function is achieved, but the device weight increases making disassembly and washing difficult
Solution Approach 1:
By merging the separation function into the conveyance turret, the patent eliminates the need for three separate cutout rolls and their associated mounting structures. This integration significantly reduces the overall device weight, making the conveyance turret lighter and easier to disassemble for washing and maintenance while preserving the lid separation capability.
3Device complexity
If a one-screw type lid supply device is used, then the structure is simplified, but the lid flange becomes damaged and abrasion powder is generated
Solution Approach 1:
The patent applies local quality by designing the cutout groove with specific geometric characteristics on the conveyance turret. The groove has a controlled depth and width that allows it to engage only the lower end of the stacked lids for separation, while the flange engagement portion maintains proper contact without excessive pressure. This localized precision in the cutout groove design prevents flange damage and abrasion powder generation while maintaining structural simplicity.
4Reliability
If conventional lid supply devices are used, then lid separation is achieved, but the total device cost increases
Solution Approach 1:
The patent merges the separation function into the conveyance turret, eliminating the need for three separate cutout rolls, their motors, and control mechanisms. This integration reduces the total component count and assembly requirements, leading to lower manufacturing costs while maintaining reliable lid separation functionality.
